Q: Transform boundingBox according to angle and rotation I am trying to implement a plastic cards detector using Vision ML Model which was trained on a custom data set. I am drawing rectangles according to bounding boxes coordinates over the camera view and it works like a charm. BUT. It doesn't react to changes in the angle, or rotation. You can see this on the screens below. The ideal solution already exists in the same Vision library, but for rectangles detection. It has topLeft, topRight, bottomLeft, bottomRight with which I can draw whatever quadrilateral, but object detection has only bounding box property which actually is CGRect (ML model really required here for future changes). I found a lot of similar answers, but they had different contexts or language or the task itself. Maybe there is some way to do it with CGAffineTransform or configure model training better? Thanks! A: You can detect the object you need using object detector model and then use VNDetectRectanglesRequest. It may be a little bit slow, but this way you don't have to train anything :)

Q: How do I make an event listener with decorators in Python? I want to make an event listener like this: @some.event async def on_ready(some_info): print(some_info) @some.event async def on_error(err): print(err) So for when something is ready, or if a message is received in like WebSockets, using this for Discord since some info is only available for when the Bot is Identified or Ready I've seen something like: def add_listener(func, name): # ... def remove_listener(func, name): # ... But I don't really know how to use it or create one A: Quick example : ################################################################################ # the code for the "framework" event1_listeners = [] event2_listeners = [] def listen_event1(func): event1_listeners.append(func) return func def listen_event2(func): event2_listeners.append(func) return func def process_event(event): if event["type"] == 1: for func in event1_listeners: func(event) elif event["type"] == 2: for func in event2_listeners: func(event) else: raise NotImplementedError(f"{event['type']=!r}") ################################################################################ # your code @listen_event1 def handle_event1_v1(event): print(f"handle_event1_v1 : {event!r}") @listen_event1 def handle_event1_v2(event): print(f"handle_event1_v2 : {event!r}") @listen_event2 def handle_event2(event): print(f"handle_event2 : {event!r}") ################################################################################ # the events processed by the framework process_event({"type": 1, "msg": "hello"}) process_event({"type": 2, "msg": "world"}) handle_event1_v1 : {'type': 1, 'msg': 'hello'} handle_event1_v2 : {'type': 1, 'msg': 'hello'} handle_event2 : {'type': 2, 'msg': 'world'} Essentially, the decorators will store the function someplace, and when an event is received, the framework iterates over the functions registered for it. Removing a listener dynamically is basically just removing the func reference from the list. The decorator in this case is simply "sugar" to not having to do event1_listeners.append(func) yourself. A: Here's a simple class-based solution I quickly coded: class Event: def __init__(self): # Initialise a list of listeners self.__listeners = [] # Define a getter for the 'on' property which returns the decorator. @property def on(self): # A declorator to run addListener on the input function. def wrapper(func): self.addListener(func) return func return wrapper # Add and remove functions from the list of listeners. def addListener(self,func): if func in self.__listeners: return self.__listeners.append(func) def removeListener(self,func): if func not in self.__listeners: return self.__listeners.remove(func) # Trigger events. def trigger(self,args = []): # Run all the functions that are saved. for func in self.__listeners: func(*args) It allows you to create an Event that functions can 'subscribe' to: evn = Event() # Some code... evn.trigger(['arg x','arg y']) The functions can both subscribe to the event with decorators: @evn.on def some_function(x,y): pass Or with the addListener method: def some_function(x,y): pass evn.addListener(some_function) You can also remove listeners: evn.removeListener(some_function) To create something similar to what you asked for you can do something like this: # some.py from event import Event class SomeClass: def __init__(self): # Private event variable self.__event = Event() # Public event variable (decorator) self.event = self.__event.on some = SomeClass() And then use it like so: # main.py from some import some @some.event async def on_ready(some_info): print(some_info) @some.event async def on_error(err): print(err)

Q: how to prerender multiple language in angular universal i am using angular universal for server side rendering and i cant figure out how to prerender multilingual routes prerender app being prerender only one language i tried to wrap whole routing into one lang parametr like en/tickets/.... but when i try to prerender i get result ✔ Prerendering routes to /Users/john/Desktop/project:name/dist/project:name/browser complete. nothing gets prerendered result angular universal 14. for translate i am using ngx-translate A: Angular Universal is a tool that allows Angular applications to be processed on the server side. This way, the pages of the application can be pre-processed and quickly displayed to the user. To pre-render multilingual routes, you can follow the steps below: Determine the routes you want to pre-render. For example, you may want to pre-process routes such as /en, /fr and /de. Open the server.ts file and add the following code snippet: app.get('/en', (req, res) => { res.render(indexHtml, { req, providers: [{ provide: 'serverUrl', useValue: ${req.protocol}://${req.get('host')} }] }); }); app.get('/fr', (req, res) => { res.render(indexHtml, { req, providers: [{ provide: 'serverUrl', useValue: ${req.protocol}://${req.get('host')} }] }); }); app.get('/de', (req, res) => { res.render(indexHtml, { req, providers: [{ provide: 'serverUrl', useValue: ${req.protocol}://${req.get('host')} }] }); }); This code snippet listens to the routes you have determined with the app.get() method and processes the requests received on these routes. We use the res.render() method to send the pre-rendered page. Open the package.json file and add the following line to the scripts section: "prerender": "ng run my-app:server:production && node dist/server.js" This line allows the Angular application to be run on the server side and pre-rendered pages to be generated. In the terminal, run the npm run prerender command to generate the pre-rendered pages. By following these steps, you can pre-render the multilingual routes of your Angular application and provide a better user experience.

I am looking for any potential ways a user might be to use SQL injection on it maybe with some examples as I haven been giving it a go myself to no avail as I am still new to this. Any pointers would be great. A: It looks like your code is vulnerable to SQL injection attacks in the addrec function. In particular, the following line of code concatenates user input directly into the SQL query string, which can allow an attacker to inject arbitrary SQL commands: cur.executescript("INSERT INTO tasks (title,body) VALUES (" + html.unescape(sqlescape(title)) + "," + html.unescape(sqlescape(body.decode())) + ");") For example, if an attacker were to provide the following input for the title field: '; DROP TABLE tasks; -- The resulting SQL query would be: INSERT INTO tasks (title,body) VALUES (''; DROP TABLE tasks; --','[base64-encoded body value]'); This query would first insert a new record with a title value of '; DROP TABLE tasks; --', and then execute a DROP statement to delete the entire tasks table. To protect against SQL injection attacks, you should use parameterized queries instead of concatenating user input into the query string. In Python, you can use the ? placeholder in your SQL query and pass the user input as a separate argument to the execute or executemany method. For example, the addrec function could be rewritten as follows: @app.route('/addrec', methods=['POST', 'GET']) def addrec(): if request.method == 'POST': con = sqlite3.connect(db) msg = "" try: # Get the user input title = request.form['title'] body = request.form['body'] key = request.form['password'] body = encode_body(body, key) # Use a parameterized query to insert the user input into the database cur = con.cursor() cur.execute("INSERT INTO tasks (title,body) VALUES (?, ?)", (title, body.decode())) # Commit the changes to the database con.commit() msg = "Record successfully added" except: con.rollback() msg = "error in insert operation" finally: return render_template("result.html", msg=msg) con.close()

Q: Can I add code/update my exported app in windows forms? So I made a Quick Notes app in Visual Studio using C# and the windows forms .NET Framework. I exported the program using the setup wizard which is part of the Microsoft visual studio installer projects extension. The app is completed but I forgot to add a bit of code. I can add it in visual studio since the project is still there but I'm not sure it will apply it to the exported app. Can anyone help? I don't want to break anything so I haven't written any new code. A: Any workflow that generates an installer (.msi, .msix, setup.exe) will need to be regenerated if code changes are made to the installed app. The installer version should be incremented and also a new ProductCode should be generated so that the newer installer has the information it needs to remove prior versions.

Q: How to get the smallest texel that wraps a triangle Assume I have the UVs of the three vertices of a triangle. What is the fastest way to get the smallest texel that wraps this triangle? That is, the mip level and the UV coordinates of this texel. A: Let us use the following notation: Let p be the index of your points in the triangle, so p in {0,1,2} Let n(p) be a 2D vector function representing the normalized texcoords in [0,1] (per component), assigned to point index p Let t(p,l) nbe the unnormalized tex coords assiged to point p for mipmap level l This means t(p,l) = n(p) * vec2(width(l), height(l)). If we want to find the mipmap level, we can do this by calculating the size of the triangle in the base level t(p,0): Let: a = t(1,0) - t(0,0) b = t(2,0) - t(0,0) a and b represent the vectors of the edges of the triangle in texture space, at the base level. So let's find the maximum individually for each dimension: x_max = max(a.x,b.x) y_max = max(a.y,b.y) These two basically describe the size of an axis-aligned bounding-box around our triangle. So we can use the longest side to find the mipmap level: m = max(x_max,y_max). Finding the right mipmap level means finding the level l for which the size m would be <= 1 texel. By going up one mip level, the value of m would be halved. so we get (with the appropriate rounding): l = floor(log2(ceil(m))) What we have now is the level where the size of the triangle would fit in one texel. This is the lower bound of the actual level that fullfills your criteria. The triangle might intersect up to 2x2 texels at level n. However, just going up one more level might not do the trick, as it might still intersect different texel in the upper-next level. In the worst case, your triangle encloses the center point of your texture, in which case, only the upmost mip level sized 1x1 will ever completely enclose your triangle completely. So a naive algorithm could be start at level l as calculated above above calculate floor(t(p,l)) for all three points Compare them. If the are all identical, you are finished, l is the result. If not all three are identical, increase l by one and repeat at step 2. The resulting l will be the level you searched for. and the UV coordinates of this texel A texel doesn't have one UV coordinate, but represents a rectangle in UV space. So it is not clear what you want, but you might want some of the following the unnormalized integer texel coords, which are just thefloor(t(p,l)) you already calculated the unnormalized coordinates of the texel center, which is just floor(t(p,l)) + vec2(0.5) the unnormalized coordinates of the barycenter of the triangle, which is just (t(0,l) + t(1,l) + t(2,l))/3.0 the normalized variant of any of the above, which is just the value divided by the size of level l

Q: How to remove all non alphanumeric characters from a string except period and space in excel? I need to remove all non alphanumeric characters from a string except period and space in Excel. A solution using VBA rather than pure excel functions be just fine. A: Insert this function into a new module in the Visual Basic Editor: Function AlphaNumericOnly(strSource As String) As String Dim i As Integer Dim strResult As String For i = 1 To Len(strSource) Select Case Asc(Mid(strSource, i, 1)) Case 48 To 57, 65 To 90, 97 To 122: 'include 32 if you want to include space strResult = strResult & Mid(strSource, i, 1) End Select Next AlphaNumericOnly = strResult End Function Now you can use this as a User Define Function, i.e. if your data is in cell A1, place this formula in an empty cell =AlphaNumericOnly(A1). If you want to convert a large range directly, i.e. replace all the non-alphanumeric characters without leaving the source, you can do this with another VBA routine: Sub CleanAll() Dim rng As Range For Each rng In Sheets("Sheet1").Range("A1:K1500").Cells 'adjust sheetname and range accordingly rng.Value = AlphaNumericOnly(rng.Value) Next End Sub Simply place this sub in the same module and execute it. Be aware though, that this will replace any formulas in the range. A: I was looking for a more elegant solution than the one I came up with. I was going to use ashleedawg's code above as it certainly is neater than my code. Ironically, mine ran 30% quicker. If speed is important (say you have a few million to do), try this: Public Function AlphaNumeric(str As String) As String Dim i As Long For i = 1 To Len(str) If InStr(1, "01234567890ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz. ", Mid(str, i, 1)) Then AlphaNumeric = AlphaNumeric & Mid(str, i, 1) Next End Function There's a surprise around every corner with VBA. I'd never imagine this would be quicker... A: Here' an alternate method of removing "whatever characters you want" from a string using pattern matching. The example below removes everything except letters, numbers, spaces and periods ([A-Z.a-z 0-9]) For improved efficiency it also utilizes VBA's seamless conversion between Strings and Byte Arrays: cleanString Function: Function cleanString(str As String) As String Dim ch, bytes() As Byte: bytes = str For Each ch In bytes If Chr(ch) Like "[A-Z.a-z 0-9]" Then cleanString = cleanString & Chr(ch) Next ch End Function More Information: For more about creating patterns for the Like operator, see: VBA: Like Operator description better info in the VB.NET: Like Operator description More about how Byte Arrays and Strings are basically interchangeable A: I have written the following code and it works as far as I tested it, it consists of two functions. The first checks whether a string is alphanumeric and the second makes the replacement (it also removes spaces) Public Function Isalphanumeric(cadena As String) As Boolean Select Case Asc(UCase(cadena)) Case 65 To 90 'letras Isalphanumeric = True Case 48 To 57 'numeros Isalphanumeric = True Case Else Isalphanumeric = False End Select End Function And here goes the remove function Function RemoveSymbols_Enhanced(InputString As String) As String Dim InputString As String Dim CharactersArray() Dim i, arrayindex, longitud As Integer Dim item As Variant i = 1 arrayindex = 0 longitud = Len(InputString) 'We create an array with non alphanumeric characters For i = 1 To longitud If Isalphanumeric(Mid(InputString, i, 1)) = False Then ReDim Preserve CharactersArray(arrayindex) CharactersArray(arrayindex) = Mid(InputString, i, 1) arrayindex = arrayindex + 1 End If Next 'For each non alphanumeric character we do a replace For Each item In CharactersArray item = CStr(item) InputString = Replace(InputString, item, "") Next End Function A: Get alphanumeric characters including spaces, +- signs and (point)commata The tricky helper function getCodes() called by AlphaNum() groups each character into five categories, where category 4 corresponds to digits, 5 to any letters, not only from A-Z, but including even ►accented or ►diacritic ones.

Q: Debugging installed libraries I have installed mbedtls on my wsl Ubuntu: sudo apt-get install -y libmbedtls-dev But I would like to debug through library code. I have downloaded source files from git repository. But does it means I must build libraries with -g option which allows produce debugging information? A: Yes, you need to build the mbed TLS libraries with the -g flag to produce debugging symbols. This will allow you to use a debugger to step through the code and see what is happening at each step. To build mbed TLS with debugging information, you can use the -g option with the make command, i.e.: make CFLAGS=-g This will build the mbed TLS libraries with the -g option and produce debugging information. You can then use GDB to debug the code.

Q: React hock useEvent TypeScript There is this code, it works on js but not on ts import { useCallback, useLayoutEffect, useRef } from 'react'; type callbackType = (...args: any[]) => any; export const useEvent = <TF extends callbackType>(callback: TF): TF => { const functionRef = useRef<TF>(callback); useLayoutEffect(() => { functionRef.current = callback; }); return useCallback((...args) => { const functionCall = functionRef.current; return functionCall(...args); }, []); }; error here: return useCallback((...args) => { TS2345: Argument of type '(...args: any[]) => any' is not assignable to parameter of type 'TF'.'(...args: any[]) => any' is assignable to the constraint of type 'TF', but 'TF' could be instantiated with a different subtype of constraint 'callbackType'. how to solve this problem without resorting to //@ts-ignore? A: I can't really explain why, but the issues seems to be with the ...args: any[] from callbackType, which could not be "respected". So I modified a bit callbackType to take two generics (one for the parameters and one for the result), and I added the constraint that the input should extend any[] (so it works well with the rest parameters), which seems to fix the issues. import { useCallback, useLayoutEffect, useRef } from "react"; type callbackType<A extends any[], R> = (...args: A) => R; export const useEvent = <A extends any[], R>( callback: callbackType<A, R> ): callbackType<A, R> => { const functionRef = useRef(callback); useLayoutEffect(() => { functionRef.current = callback; }); return useCallback((...args) => { const functionCall = functionRef.current; return functionCall(...args); }, []); }; function Component() { const cb = useEvent((x: number, y: string) => { return "Hello world"; }); cb(1, "test"); return null; } A: import {useRef, useLayoutEffect, useCallback} from 'react'; type callbackType = (...args: Array<any>) => any; interface useEventOverload { <TF extends callbackType>(callback: TF): TF; <TF extends callbackType>(callback: TF): any; } export const useEvent: useEventOverload = (callback) => { const callbackRef = useRef(callback); useLayoutEffect(() => { callbackRef.current = callback; }); return useCallback((...args: any) => { return callbackRef.current(...args); }, []); };

Q: How to use vue-toastification I just migrated my project created in vue 3 to nuxt 3. Previously I used the vue-toastification module but now I don't know how to import it correctly. My code using this module. import { useToast, POSITION } from 'vue-toastification' const toast = useToast() export default { methods: { copy(text) { toast.success('Copied!', { timeout: 2000, position: POSITION.BOTTOM_CENTER, }) navigator.clipboard.writeText(text) } } } In Vue I had to do app.use(Toast) but Nuxt does not have an index.js file. Adding modules: ['vue-toastification/nuxt'] in nuxt.config.js does not work because I get an error. A: If you want it to be available globally, you can install it as a Nuxt plugin as explained in the official docs or in this other answer. vue-toastification is probably a client-side only plugin, hence you would probably want to use it as /plugins/vue-toastificaton.client.js like this import { defineNuxtPlugin } from '#app' import Toast from "vue-toastification" import "vue-toastification/dist/index.css" // if needed export default defineNuxtPlugin(nuxtApp => { nuxtApp.vueApp.use(Toast) }) Then, you should be able to use it in your components with either Composition API or Options API (I think).

When I run the program nothing prints. It seems like my query is not executing. I am not sure what I am doing wrong. Also I am getting an error when I put -7 for my startDate. Why query is not executing please? I don't know swift enough to know what is the problem. Can someone help me please? guard let startDate = Calendar.current.date(byAdding: DateComponents (day: -7), to: Date()) else { fatalError("*** Unable to create the start date ***") } let endDate = Date() if let sleepType = HKObjectType.categoryType(forIdentifier: HKCategoryTypeIdentifier.sleepAnalysis){ let predicate = HKQuery.predicateForSamples(withStart: startDate, end: endDate, options: []) let sortDescriptor = NSSortDescriptor(key: HKSampleSortIdentifierEndDate, ascending: false) let query = HKSampleQuery(sampleType: sleepType, predicate: predicate, limit: HKObjectQueryNoLimit, sortDescriptors: [sortDescriptor]) { (query, tmpResult, error) -> Void in if let result = tmpResult { // do something with my data for item in result { if let sample = item as?

The Calendar.current.date(byAdding:to:) method requires a DateComponents object as its first argument, but you are providing an integer (-7). This is causing the method to return nil, which triggers the fatalError() call and terminates the program. To fix this issue, you can create a DateComponents object with the desired number of days and pass it to the date(byAdding:to:) method instead of the integer. For example: let dateComponents = DateComponents(day: -7) guard let startDate = Calendar.current.date(byAdding: dateComponents, to: Date()) else { fatalError("*** Unable to create the start date ***") } This should create a Date object that is 7 days before the current date and assign it to the startDate variable. Additionally, it looks like you are not printing the values of the startDate and endDate variables, or the values of the sleepType object. To print these values, you can add some print() statements after you create the variables, like this: // Print the start and end dates print("Start date:", startDate) print("End date:", endDate) // Print the sleep type print("Sleep type:", sleepType) This should print the values of these variables to the console, which can help you verify that they are being created correctly. I hope this helps! Let me know if you have any other questions.

Q: How do I create a function that reverses an array in JavaScript? I tried with the following code but when I run it the function is not shown reversed although the number I chose is even: const myArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; const number = 32; const myReversedArray = number => { if (number % 2 === 0) { return myArray.reverse(); } else { return myArray; } } console.log(myReversedArray()); I expected the function to be shown in reverse since the number I chose is even, but instead it is shown in the normal order (1, 2, 3, 4, 5, 6, 7, 8, 9, 10). A: There are a few issues with the code. First, the number parameter in the myReversedArray function is not being used. It should be used to determine whether to reverse the array or not. Second, the myReversedArray function is not being called with any arguments, so the number parameter is not being set to anything. This can be fixed by passing the number variable as an argument when calling the function. Third, the myReversedArray function does not return anything if the number is not even, so it will always return undefined in that case. This can be fixed by adding a return statement that returns the original array if number is not even. const myArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]; const number = 32; const myReversedArray = number => { if (number % 2 === 0) { return myArray.reverse(); } else { return myArray; // Return the original array if number is not even } } console.log(myReversedArray(number)); // Pass the number variable as an argument

Q: How to click Recyclerview position with specific View Visible- Espresso I am writing UI Test for my App using Espresso. The screen shows a Recyclerview with list of shops that have status OPEN or CLOSED. Depending upon the data the openTextView or closedTextview is shown and are hidden by default. Below is my test case scenario: Check if screen is visible Check if Recyclerview is visible Check if Recyclerview has atleast one shop with OPEN status Click on first found OPEN shop Check if details screen shows up ISSUE: I tried to click the first OPEN status item but it is throwing Exception. Below is the code @Test fun openShopTest() { onView(withText(“Shops")).check(matches(isDisplayed())) onView(withId(R.id.rvShops)).check(matches(isDisplayed())) //There is at least one open shop visible onView(withId(R.id.rvShops)) .perform(RecyclerViewActions.scrollToHolder(first(withOpenText()))) //User clicks on open shop onView(allOf(withId(R.id.rvShops), isDisplayed())) .perform(actionOnItem<ListAdapter.ListViewHolder>(withChild(withText(“Open”)), click())) //Screen with details appear onView(withText("Details”)).check(matches(isDisplayed())) } fun withOpenText(): Matcher<RecyclerView.ViewHolder> { return object : BoundedMatcher<RecyclerView.ViewHolder, ListAdapter.ListViewHolder>( ListAdapter.ListViewHolder::class.java ) { override fun describeTo(description: Description) { description.appendText("No ViewHolder found with Open Status Visible") } override fun matchesSafely(item: ListAdapter.ListViewHolder): Boolean { val openTextView = item.itemView.findViewById(R.id.openTextView) as TextView return openTextView.isVisible } } } Below is the exception: androidx.test.espresso.PerformException: Error performing 'performing ViewAction: single click on item matching: holder with view: has child: with text: is "Open"' on view '(with id: mypackagename:id/rvShops and is displayed on the screen to the user)'. at androidx.test.espresso.PerformException$Builder.build(PerformException.java:82) at androidx.test.espresso.base.DefaultFailureHandler.getUserFriendlyError(DefaultFailureHandler.java:79) at androidx.test.espresso.base.DefaultFailureHandler.handle(DefaultFailureHandler.java:51) at androidx.test.espresso.ViewInteraction.waitForAndHandleInteractionResults(ViewInteraction.java:312) at androidx.test.espresso.ViewInteraction.desugaredPerform(ViewInteraction.java:173) at androidx.test.espresso.ViewInteraction.perform(ViewInteraction.java:114) at mypackagename.MyUITest.openShopTest(MyUITest.kt:77) ... 32 trimmed Caused by: androidx.test.espresso.PerformException: Error performing 'scroll RecyclerView to: holder with view: has child: with text: is "Open"' on view 'RecyclerView{id=2131231032, res-name=rvShops, visibility=VISIBLE, width=1080, height=2047, has-focus=false, has-focusable=true, has-window-focus=true, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=true, is-layout-requested=false, is-selected=false, layout-params=androidx.constraintlayout.widget.ConstraintLayout$LayoutParams@295fec9, tag=null, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=0.0, child-count=12}'. at androidx.test.espresso.PerformException$Builder.build(PerformException.java:82) at androidx.test.espresso.contrib.RecyclerViewActions$ScrollToViewAction.perform(RecyclerViewActions.java:381) at androidx.test.espresso.contrib.RecyclerViewActions$ActionOnItemViewAction.perform(RecyclerViewActions.java:221) at androidx.test.espresso.ViewInteraction$SingleExecutionViewAction.perform(ViewInteraction.java:356) at androidx.test.espresso.ViewInteraction.doPerform(ViewInteraction.java:248) at androidx.test.espresso.ViewInteraction.access$100(ViewInteraction.java:63) at androidx.test.espresso.ViewInteraction$1.call(ViewInteraction.java:153) at androidx.test.espresso.ViewInteraction$1.call(ViewInteraction.java:150) at java.util.concurrent.FutureTask.run(FutureTask.java:264) at android.os.Handler.handleCallback(Handler.java:938) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loopOnce(Looper.java:226) at android.os.Looper.loop(Looper.java:313) at android.app.ActivityThread.main(ActivityThread.java:8751) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:571) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1135) Caused by: java.lang.RuntimeException: Found 0 items matching holder with view: has child: with text: is "Open", but position -1 was requested. at androidx.test.espresso.contrib.RecyclerViewActions$ScrollToViewAction.perform(RecyclerViewActions.java:361) What i have tried? I had an idea that maybe openTextView or closedTextview are not always visible so that might be causing the problem. I tried by making both always visible as well. I followed the steps mentioned in answers of this question but the same excpetion shows up. What is required? Click on Recyclerview row where openTextView is visible Get position of row where openTextView is visible; so that i can use atPosition function and click the row. Can somebody please help me out with this? Any help will be appreciated. Thanks A: The idea is to custom the View action of Espresso. object MyViewAction { fun clickChildViewWithIdAndText(id: Int, text: String): ViewAction { return object: ViewAction { override fun getConstraints(): Matcher<View> { return withText(text) } override fun getDescription(): String { return "Click on a child view with specified id and text" } override fun perform(uiController: UiController?, view: View) { val v: View = view.findViewById(id) v.performClick() } } } } onView(withId(R.id.rv_home)).perform( RecyclerViewActions.actionOnItemAtPosition<ListAdapter.ListViewHolder>( 0, MyViewAction.clickChildViewWithIdAndText(R.id.tv_id, "OPEN") ) ); By the way, you can use some powerful testing libraries which are built on top of Espresso such as Barista or Kakao. It helps your testing code to be much more readable and elegant. For example, you can assert the item displayed at position x with text y in the list view with just one line of code import com.adevinta.android.barista.assertion.BaristaListAssertions.assertDisplayedAtPosition assertDisplayedAtPosition(R.id.rv_list, x, R.id.tv_id, y) A: It looks like the issue is with the withOpenText() method that you are using to find the viewholder with the "Open" text. This method is returning a Matcher object that matches a RecyclerView.ViewHolder that has a child TextView with the text "Open" and is visible. However, in your test case, you are using the withChild() matcher to find a RecyclerView.ViewHolder that has a child with the text "Open" and then trying to perform a click action on that viewholder. In order for this to work, you will need to modify the withOpenText() method to return a ViewAction that can be performed on the matched viewholder, instead of a Matcher object. You can do this by using the ViewActions.click() method to create a ViewAction that will click on the matched viewholder. Here is an example of how you can modify the withOpenText() method to return a ViewAction instead of a Matcher: fun withOpenText(): ViewAction { return object : ViewAction { override fun getConstraints(): Matcher<View> { return allOf( isDescendantOfA(withId(R.id.rvShops)), withChild(withText("Open")) ) } override fun getDescription(): String { return "Click on ViewHolder with Open Status Visible" } override fun perform(uiController: UiController, view: View) { val openTextView = view.findViewById(R.id.openTextView) as TextView if (openTextView.isVisible) { ViewActions.click().perform(uiController, view) } } } } Then, you can use the withOpenText() method in your test case like this: @Test fun openShopTest() { onView(withText(“Shops")).check(matches(isDisplayed())) onView(withId(R.id.rvShops)).check(matches(isDisplayed())) //There is at least one open shop visible onView(withId(R.id.rvShops)) .perform(RecyclerViewActions.scrollToHolder(first(withOpenText()))) //Screen with details appear onView(withText("Details”)).check(matches(isDisplayed())) } This should fix the issue and allow you to click on the first open shop in the recyclerview.

How to click Recyclerview position with specific View Visible- Espresso

I am writing UI Test for my App using Espresso. The screen shows a Recyclerview with list of shops that have status OPEN or CLOSED. Depending upon the data the openTextView or closedTextview is shown and are hidden by default. Below is my test case scenario: Check if screen is visible Check if Recyclerview is visible Check if Recyclerview has atleast one shop with OPEN status Click on first found OPEN shop Check if details screen shows up ISSUE: I tried to click the first OPEN status item but it is throwing Exception. Below is the code @Test fun openShopTest() { onView(withText(“Shops")).check(matches(isDisplayed())) onView(withId(R.id.rvShops)).check(matches(isDisplayed())) //There is at least one open shop visible onView(withId(R.id.rvShops)) .perform(RecyclerViewActions.scrollToHolder(first(withOpenText()))) //User clicks on open shop onView(allOf(withId(R.id.rvShops), isDisplayed())) .perform(actionOnItem<ListAdapter.ListViewHolder>(withChild(withText(“Open”)), click())) //Screen with details appear onView(withText("Details”)).check(matches(isDisplayed())) } fun withOpenText(): Matcher<RecyclerView.ViewHolder> { return object : BoundedMatcher<RecyclerView.ViewHolder, ListAdapter.ListViewHolder>( ListAdapter.ListViewHolder::class.java ) { override fun describeTo(description: Description) { description.appendText("No ViewHolder found with Open Status Visible") } override fun matchesSafely(item: ListAdapter.ListViewHolder): Boolean { val openTextView = item.itemView.findViewById(R.id.openTextView) as TextView return openTextView.isVisible } } } Below is the exception: androidx.test.espresso.PerformException: Error performing 'performing ViewAction: single click on item matching: holder with view: has child: with text: is "Open"' on view '(with id: mypackagename:id/rvShops and is displayed on the screen to the user)'. at androidx.test.espresso.PerformException$Builder.build(PerformException.java:82) at androidx.test.espresso.base.DefaultFailureHandler.getUserFriendlyError(DefaultFailureHandler.java:79) at androidx.test.espresso.base.DefaultFailureHandler.handle(DefaultFailureHandler.java:51) at androidx.test.espresso.ViewInteraction.waitForAndHandleInteractionResults(ViewInteraction.java:312) at androidx.test.espresso.ViewInteraction.desugaredPerform(ViewInteraction.java:173) at androidx.test.espresso.ViewInteraction.perform(ViewInteraction.java:114) at mypackagename.MyUITest.openShopTest(MyUITest.kt:77) ... 32 trimmed Caused by: androidx.test.espresso.PerformException: Error performing 'scroll RecyclerView to: holder with view: has child: with text: is "Open"' on view 'RecyclerView{id=2131231032, res-name=rvShops, visibility=VISIBLE, width=1080, height=2047, has-focus=false, has-focusable=true, has-window-focus=true, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=true, is-layout-requested=false, is-selected=false, layout-params=androidx.constraintlayout.widget.ConstraintLayout$LayoutParams@295fec9, tag=null, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=0.0, child-count=12}'. at androidx.test.espresso.PerformException$Builder.build(PerformException.java:82) at androidx.test.espresso.contrib.RecyclerViewActions$ScrollToViewAction.perform(RecyclerViewActions.java:381) at androidx.test.espresso.contrib.RecyclerViewActions$ActionOnItemViewAction.perform(RecyclerViewActions.java:221) at androidx.test.espresso.ViewInteraction$SingleExecutionViewAction.perform(ViewInteraction.java:356) at androidx.test.espresso.ViewInteraction.doPerform(ViewInteraction.java:248) at androidx.test.espresso.ViewInteraction.access$100(ViewInteraction.java:63) at androidx.test.espresso.ViewInteraction$1.call(ViewInteraction.java:153) at androidx.test.espresso.ViewInteraction$1.call(ViewInteraction.java:150) at java.util.concurrent.FutureTask.run(FutureTask.java:264) at android.os.Handler.handleCallback(Handler.java:938) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loopOnce(Looper.java:226) at android.os.Looper.loop(Looper.java:313) at android.app.ActivityThread.main(ActivityThread.java:8751) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:571) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1135) Caused by: java.lang.RuntimeException: Found 0 items matching holder with view: has child: with text: is "Open", but position -1 was requested. at androidx.test.espresso.contrib.RecyclerViewActions$ScrollToViewAction.perform(RecyclerViewActions.java:361) What i have tried?

Q: Github remote permission denied I'm trying to upload my repo on github and go through all the steps upto: git push -u origin master at that point it gives me the following error: remote: Permission to samrao2/manager-4.git denied to samrao1. fatal: unable to access 'https://github.com/samrao2/manager-4.git/': The requested URL returned error: 403 I think the issue is that i was logged into another Git account before "samrao1" and now i am trying to push to "samrao2". Can someone help me reset this to where i can successfully push to "samrao2". I am assuming i will be prompted for my password the first time i try to do it. A: Unable to access https means: this has nothing to do with SSH (and switching to SSH, while possible, does not explain the original issue) This has to do with credential caching, meaning Git will be default provide the credentials (GitHub account and password PAT Personal Access Token) of the old account while you are trying to push to the new account. Reminder, most Git repository hosting service uses token as password, not your actual user account password. For instance, GitHub no longer accept password since Aug. 2021. See if you have a credential helper that would have cached your (old account) credentials (username/password) used to authentication you. git config credential.helper On Mac, as commented by Arpit J, just goto/open your keychain access->search for github.com related file->and edit credentials there. See "Updating credentials from the OSX Keychain" On Windows (And, in 2021, possibly Linux or even Mac), that would be the Windows Credential Managers GCMC: Git Credential Manager. Open the Windows Credential Store, and see if the first user is registered there: delete that entry, and you will be able to authenticate with the second user. (Here is an example for BitBucket) In command-line (see git credential), for a manager core credential helper: Get the old password or token: printf "protocol=https\nhost=github.com\nusername=<me>" | \ git credential-manager-core get # output: protocol=https host=github.com username=<me> password=<old_password_or_token> Remove the old password: printf "protocol=https\nhost=github.com\nusername=<me>" | \ git credential-manager-core erase (Replace <me> by your GitHub user account name) A: Resolved this error by updating my username and credentials: git config user.name "new name" git config credential.username "new name" A: I'm not sure what the issue is, but since you mentioned not knowing what having the "right keys installed" means, I'm going to assume you have not set up your computer to authenticate to your Github repository via SSH. This guide should show you how to do that: Adding a new SSH key to your Github account Also, I would suggesting using 'git://github.com/samrao2/manager-4.git/' for your remote URL rather than 'https://github.com/samrao2/manager-4.git/'. The latter requires you to enter a password each time, whereas the former will authenticate via SSH, which is far less irritating. You can change the remote URL in your repository to use the git protocol, instead of https, by typing: git remote set-url origin git://github.com/samrao2/manager-4.git from within your project directory. A: If you are using MacOS, you can go to KeyChain Access, Search for "GitHub", then when then result "github.com" pops up, change the account or password to your new account, and save. Then you are all set! A: Here 403 (error) means credentials errors or that you don’t have permission to push. Solution For Windows click on window button > credential manager > Windows credentials > Generic credentials Next, remove or edit the Github keys. For Mac 1-In Finder, search for the Keychain Access app. 2In Keychain Access, search for github.com. 3-Find the "internet password" entry for github.com. 4-Edit or delete the entry accordingly. A: Appreciating VonC's answer. To simplify and add into it, one can follow below simple steps: Remove all GitHub entries from (Windows) Credential Manager Set useHttpPath = true in Git global configuration git config --global credential.useHttpPath true You can validate this by checking git config --global -e This will create a different entry for each user account. A: I had a similar issue and what found out its two things you need to verify: The key chain issue that has adequately been discussed above; Git recently stopped using passwords, you need to instead generate a personal access token. NOTE THIS IS IMPORTANT and the source of the problem I had, on the creation of token ensure permission are granted to the token on Github under developer option. A: Multiple users generate their own ssh key, Generating a new SSH key and adding it to the ssh-agent Adding a new SSH key to your GitHub account Alice Repository, git bash: git config user.name "Alice" git config user.email "alice@email.com" eval $(ssh-agent -s), ssh-add ~/.ssh/alice.private ssh -T git@github.com, Testing your SSH connection Git other operations Bob Repository, git bash: git config user.name "Bob" git config user.email "bob@email.com" eval $(ssh-agent -s), ssh-add ~/.ssh/bob.private ssh -T git@github.com, Testing your SSH connection Git other operations A: I was facing the same issue I have resolved using below command git config --global credential.useHttpPath true A: The problem is you are trying to push into new github account using old github account's ssh key, so generate a new SSH key for the new github account using this link https://help.github.com/en/github/authenticating-to-github/error-permission-to-userrepo-denied-to-userother-repo and then add it your github account. After this try to push, it works A: I have one personal account and one business account at Github. I commit and push changes to both accounts at the same time. What I did was 1) to run personal and business projects at separate sessions; 2) to set the URL for one account with an SSH link, and leave the URL as normal (HTTPS) for another account. A: You can solve this issue by revoking the access of 2nd account "samrao1" from that specific repo that you have previously connected. A: just go to Control Panel\User Accounts\Credential Manager\Edit Generic Credential and update your git Credential A: if you are still having problems with the same, uninstall git and re-install again. That worked for me . thanks A: Check your personal access token. Edit the scopes in your token. I checked all the access options in the token. Doing this, the error did not come. https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token A: ONLY IF you've used git cli BEFORE on your machine Then simply open the credential manager on your system by pressing start button and type "Credential Manager" and switch to the "Windows Credentials" tab. Delete the existing saved account associated with https://github.com like following: Now try pushing code again, this time an authentication prompt will be popped up, authenticate your github account and congratulations, your code is hosted onto the given branch of desired repository. A: I faced same problem and then removed the git credential from windows credential manager A: Important: Remember to set your token permissions correctly. I had the same problem until I changed the permissions to allow full repo access: A: If you're using git credentials helper open the ~/.git-credentials file and change your token if it is expired, check also your GitHub username if it's correct!

Q: Loop a Map Type after call an async method i have this method inside a class Map<String, String> value = {}; bool isReady = false; void getData() async { try { Map<String, String> data = await CustomerData().getService(selectedService); isReady = true; setState(() { value = data; }); } catch (e) { print(e); } } i'd like to loop the results inside a widget so: @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text('Customer'), ), body: Column( mainAxisAlignment: MainAxisAlignment.spaceBetween, crossAxisAlignment: CrossAxisAlignment.stretch, children: <Widget>[ value.forEach((key, value) { Text('$key: $value'), }) ], ), ); } the only solution that i found is this but i don't like it @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text('Customer'), ), body: Column( mainAxisAlignment: MainAxisAlignment.spaceBetween, crossAxisAlignment: CrossAxisAlignment.stretch, children: <Widget>[ Text(isReady ? 'Service: value["deliver"]' : '?'), Text(isReady ? 'Status: value["status"]' : '?'), Text(isReady ? 'Note: value["note"]' : '?'), ], ), ); } is possible loop a Map type that comes from a method async inside a Widget? A: To loop through a Map in a Widget, you can use a ListView.builder widget. The ListView.builder widget allows you to build a list of items on-demand. This is useful when the number of items in your list is not known beforehand, or when your list is very large. To use the ListView.builder widget, you need to provide a builder function that returns a Widget for each item in the Map. Inside the builder function, you can access the key and value of each item in the Map using the index parameter. Here's an example of how you can use the ListView.builder widget to loop through a Map: @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text('Customer'), ), body: Column( mainAxisAlignment: MainAxisAlignment.spaceBetween, crossAxisAlignment: CrossAxisAlignment.stretch, children: <Widget>[ // Use a ListView.builder widget to loop through the Map ListView.builder( // The number of items in the list is the number of items in the Map itemCount: value.length, // The builder function returns a widget for each item in the Map itemBuilder: (context, index) { // Access the key and value of each item in the Map using the index var key = value.keys.elementAt(index); var val = value.values.elementAt(index); // Return a Text widget with the key and value of the Map item return Text('$key: $val'); }, ), ], ), ); } Note that you need to make sure that the Map is initialized before you try to access its items in the build method. You can do this by using the isReady variable that you defined in your code. You can check if the Map is ready by checking if the isReady variable is true. If the Map is not ready, you A: Use FutureBuilder to get future and then Listview.builder in the same way @haris told you.

Q: RabbitMQ same message to each consumer I have implemented the example from the RabbitMQ website: RabbitMQ Example I have expanded it to have an application with a button to send a message. Now I started two consumer on two different computers. When I send the message the first message is sent to computer1, then the second message is sent to computer2, the thrid to computer1 and so on. Why is this, and how can I change the behavior to send each message to each consumer? A: Why is this As noted by Yazan, messages are consumed from a single queue in a round-robin manner. The behavior your are seeing is by design, making it easy to scale up the number of consumers for a given queue. how can I change the behavior to send each message to each consumer? To have each consumer receive the same message, you need to create a queue for each consumer and deliver the same message to each queue. The easiest way to do this is to use a fanout exchange. This will send every message to every queue that is bound to the exchange, completely ignoring the routing key. If you need more control over the routing, you can use a topic or direct exchange and manage the routing keys. Whatever type of exchange you choose, though, you will need to have a queue per consumer and have each message routed to each queue. A: you can't it's controlled by the server check Round-robin dispatching section It decides which consumer turn is. i'm not sure if there is a set of algorithms you can pick from, but at the end server will control this (i think round robin algorithm is default) unless you want to use routing keys and exchanges A: I would see this more as a design question. Ideally, producers should create the exchanges and the consumers create the queues and each consumer can create its own queue and hook it up to an exchange. This makes sure every consumer gets its message with its private queue. A: What youre doing is essentially 'worker queues' model which is used to distribute tasks among worker nodes. Since each task needs to be performed only once, the message is sent to only one node. If you want to send a message to all the nodes, you need a different model called 'pub-sub' where each message is broadcasted to all the subscribers. The following link shows a simple pub-sub tutorial https://www.rabbitmq.com/tutorials/tutorial-three-python.html

Q: include external files in processmaker 4 php scripts I am using processmaker 4 comunity, I need to run a PHP script that needs to include some external files with classes I defined. Since the php executor runs in a container it does not have access to the file system in my computer, how can I make the included files available in the executor container? I understand that one of the option would be to create a new executor with a dockerfile that will copy the required php files in the docker's executor image, but that means rebuilding the image each time I make a change on the included files. It would be great if I could mount a directory of my local host to the executors container, but have not figurer out if I can do that in processmaker. Any suggestions or information on how to work arround this? A: It is not possible to mount a directory from your local host to the executor container in ProcessMaker. However, there are a few options you can consider to make your PHP files available in the executor container. One option is to include the PHP files directly in your PHP script using the include or require statements. This way, you can specify the path to the PHP file relative to the location of your PHP script, and the executor container will be able to access it. For example: include "./path/to/file.php"; Another option is to package the PHP files into a ZIP archive and use the pm.downloadFile function in ProcessMaker to download the ZIP file to the executor container. You can then extract the ZIP file and access the PHP files as needed. Finally, you can build a custom executor image that includes the PHP files you need. This will require rebuilding the image each time you make changes to the PHP files, but it will allow you to easily access the files in the executor container without having to download or include them in your PHP script. A: In order to do this, you will need to ensure that the PHP executor has access to the files. One option would be to build a new PHP executor image that includes the necessary PHP files. This would involve creating a Dockerfile that installs the necessary dependencies and copies the PHP files into the image. Then, you can use this image as the PHP executor in ProcessMaker. Another option would be to mount a local directory from your host machine to the PHP executor container. This would allow you to access the local PHP files from within the container. To do this, you will need to use the -v flag when running the PHP executor container. For example: docker run -v /path/to/local/php/files:/path/to/php/files \ -e PM_PHP_EXECUTOR_IMAGE=php:7.4-cli \ processmaker/pm4-php-executor:4.0.23 This will mount the local directory /path/to/local/php/files from your host machine to the /path/to/php/files directory in the PHP executor container. You can then use the PHP files in the mounted directory from within your workflow. It's worth noting that using a mounted directory like this can make it easier to update the PHP files, since you don't need to rebuild the PHP executor image each time you make a change. However, there are some potential drawbacks to this approach, such as increased complexity and potential security concerns. I hope this helps!

Create individual hover text with background color over circle photo grid elements, CSS/HTML

I have been struggling to create hover text and circular background color elements that appear over my circular image grid on my website. This requires some combination of the HTML and CSS I have I imagine. I think this is difficult for me due to the way I have the grid and positioning setup. So it is hard to position the overlap hover element properly...`Below is my HTML and corresponding CSS code.

Other problem is that the container doesn't exit after the error which makes the services to fail. Container will be restarted by our orchestration layer if it exits. (this is a different problem that as we use Bitnami images) I also didn't find many production examples out there that uses kraft mode. Are we missing some configuration or do we need to change any default configuration values such as request timeout in Kraft mode? A: It looks like your Kafka cluster is having issues with its Raft-based state management. The KAFKA_ENABLE_KRAFT configuration parameter indicates that your cluster is using Raft for state management, and the log messages indicate that one of the nodes is timing out when trying to fetch state from another node. This can happen if the network connection between the nodes is unstable, or if one of the nodes is running on a machine with inadequate resources (e.g. not enough memory or CPU). I would recommend checking the network connectivity between the nodes to make sure there are no issues there. You can also try increasing the KAFKA_CFG_CONTROLLER_QUORUM_VOTERS configuration parameter to ensure that a quorum of nodes is always available for state management, which can help prevent these kinds of timeouts. Additionally, you may want to monitor the resources (e.g. memory, CPU) available on the machines running your Kafka nodes to make sure they are not being overloaded.

Q: Plot one series for one column with Polars dataframe and Plotly I can't find how to plot these two series A and B with time on X. from numpy import linspace import polars as pl import plotly.express as px import plotly.io as pio pio.renderers.default = 'browser' times = linspace(1, 6, 10) df = pl.DataFrame({ 'time': times, 'A': times**2, 'B': times**3, }) fig = px.line(df) fig.show() Data keep showing as 10 series with 3 points, instead of 2 series with 10 points and the first column as X values. Edit: This line: fig = px.line(df, x='time', y=['A', 'B']) produces this error: ValueError: Value of 'x' is not the name of a column in 'data_frame'. Expected one of [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] but received: time Using polars 0.15.0 and plotly 5.11.0 A: You use Polars Dataframe instead of Pandas dataframe and indexing is a little different here and what is why you have this error. In order to plot it, one way to do it is to convert the dataframe from Polars to Pandas on the fly by using to_pandas(): fig = px.line(df.to_pandas(),x='time', y=['A', 'B']) Output You can also use this way: fig = px.line(x=df['time'], y=[df["A"],df["B"]]) A: In your code, you can use the line() function to plot the A and B columns from your DataFrame, which contain the time-series data for the two series. You can then set the x and y parameters of the line() function to specify which column should be used for the X-axis and which columns should be used for the Y-axis. Here's an example of how you can use the line() function to plot the A and B columns from your DataFrame with time on the X-axis: # Import the necessary modules from numpy import linspace import plotly.express as px # Create a DataFrame with time-series data for two series times = linspace(1, 6, 10) df = pl.DataFrame({ 'time': times, 'A': times**2, 'B': times**3, }) # Use the line() function to plot the A and B columns from the DataFrame fig = px.line(df, x='time', y=['A', 'B']) # Show the plot fig.show() This will create a line chart with the A and B columns from your DataFrame as the data series, and the time column as the X-axis. The resulting plot should show the two series with time on the X-axis.

Perhaps a more concrete example might help explain what I'm after. Say I have a DataFrame defined as: import pyspark.sql.functions as func from pyspark.sql import SparkSession spark = SparkSession.builder.getOrCreate() source_df = spark.createDataFrame( [("pru", 23, "finance"), ("paul", 26, "HR"), ("noel", 20, "HR")], ["name", "age", "department"], ) source_df.createOrReplaceTempView("people") sqlDF = spark.sql("SELECT name, age, department FROM people") df = sqlDF.groupBy("department").agg(func.max("age").alias("max_age")) df.show() which returns: +----------+--------+ |department|max_age | +----------+--------+ | finance| 23| | HR| 26| +----------+--------+ The columns that are referenced by df are [department, age]. Is it possible to get that list of referenced columns programatically? Thanks to Capturing the result of explain() in pyspark I know I can extract the plan as a string: df._sc._jvm.PythonSQLUtils.explainString(df._jdf.queryExecution(), "formatted") which returns: == Physical Plan == AdaptiveSparkPlan (6) +- HashAggregate (5) +- Exchange (4) +- HashAggregate (3) +- Project (2) +- Scan ExistingRDD (1) (1) Scan ExistingRDD Output [3]: [name#0, age#1L, department#2] Arguments: [name#0, age#1L, department#2], MapPartitionsRDD[4] at applySchemaToPythonRDD at NativeMethodAccessorImpl.java:0, ExistingRDD, UnknownPartitioning(0) (2) Project Output [2]: [age#1L, department#2] Input [3]: [name#0, age#1L, department#2] (3) HashAggregate Input [2]: [age#1L, department#2] Keys [1]: [department#2] Functions [1]: [partial_max(age#1L)] Aggregate Attributes [1]: [max#22L] Results [2]: [department#2, max#23L] (4) Exchange Input [2]: [department#2, max#23L] Arguments: hashpartitioning(department#2, 200), ENSURE_REQUIREMENTS, [plan_id=60] (5) HashAggregate Input [2]: [department#2, max#23L] Keys [1]: [department#2] Functions [1]: [max(age#1L)] Aggregate Attributes [1]: [max(age#1L)#12L] Results [2]: [department#2, max(age#1L)#12L AS max_age#13L] (6) AdaptiveSparkPlan Output [2]: [department#2, max_age#13L] Arguments: isFinalPlan=false which is useful, however its not what I need. I need a list of the referenced columns. Is this possible? Perhaps another way of asking the question is... is there a way to obtain the explain plan as an object that I can iterate over/explore? A: There is an object for that unfortunately its a java object, and not translated to pyspark. You can still access it with Spark constucts: >>> df._jdf.queryExecution().executedPlan().apply(0).output().apply(0).toString() u'department#1621' >>> df._jdf.queryExecution().executedPlan().apply(0).output().apply(1).toString() u'max_age#1632L' You could loop through both the above apply to get the information you are looking for with something like: plan = df._jdf.queryExecution().executedPlan() steps = [ plan.apply(i).toString() for i in range(1,100) if not isinstance(plan.apply(i), type(None)) ] Bit of a hack but apparently size doesn't work. A: Yes, it is possible to obtain a list of source columns that are being referenced by a PySpark DataFrame. To do this, you can use the DataFrame's df.columns attribute, which returns a list of the column names in the DataFrame. In your example, this would be df.columns which would return ['department', 'max_age']. Alternatively, you can also use the df.dtypes attribute, which returns a list of tuples containing the column names and their data types. For example, df.dtypes would return [('department', 'string'), ('max_age', 'bigint')].

Q: How do I copy all folder contents from one location to another location in Python? I have been trying to make a python file that will copy contents from one folder to another. I would like it to work on any Windows system that I run it on. It must copy ALL things ... i need solution to this problem. A: Here is one way to do this using the shutil module in Python: import shutil # Replace the source and destination paths with the appropriate paths on your system src_dir = "C:\\source\\folder" dst_dir = "C:\\destination\\folder" # Use the shutil.copytree function to copy everything from the source directory to the destination directory shutil.copytree(src_dir, dst_dir) This will copy all files and subdirectories from src_dir to dst_dir. Note that dst_dir must not already exist, otherwise the copytree function will raise an error. You can also use the copy function from the shutil module to copy individual files. For example: import shutil # Replace the source and destination paths with the appropriate paths on your system src_file = "C:\\source\\folder\\file.txt" dst_file = "C:\\destination\\folder\\file.txt" # Use the shutil.copy function to copy the file shutil.copy(src_file, dst_file) This will copy the file at src_file to the destination at dst_file. If dst_file already exists, it will be overwritten. You can use these functions in a loop to iterate over all files in a directory and copy them to the destination directory. Here is an example: import os import shutil # Replace the source and destination paths with the appropriate paths on your system src_dir = "C:\\source\\folder" dst_dir = "C:\\destination\\folder" # Create the destination directory if it does not already exist if not os.path.exists(dst_dir): os.makedirs(dst_dir) # Iterate over all files in the source directory for filename in os.listdir(src_dir): # Construct the full paths for the source and destination files src_file = os.path.join(src_dir, filename) dst_file = os.path.join(dst_dir, filename) # Use the shutil.copy function to copy the file shutil.copy(src_file, dst_file) A: import shutil import os # Path to the directory source = 'C:/path/to/source/folder' # Path to the destination directory destination = 'C:/path/to/destination/folder' # Copy contents from source to destination shutil.copytree(source, destination) # List all the files in source directory source_files = os.listdir(source) # Iterate over all the files in source directory for file_name in source_files: # Create full path of file in source directory full_file_name = os.path.join(source, file_name) # If file is a directory, create corresponding directory in destination # directory if os.path.isdir(full_file_name): shutil.copytree(full_file_name, os.path.join(destination, file_name)) else: # Copy the file from source to destination shutil.copy2(full_file_name, destination)

This is a work around which I think should solve your problem. But I am not really sure if there are change in class names in deferent versions of streamlit. st.markdown(""" <style> ul[class="css-wjbhl0 e1fqkh3o9"]{ position: relative; padding-top: 2rem; display: flex; justify-content: center; flex-direction: column; align-items: center; } .css-17lntkn { font-weight: bold; font-size: 20px; color: yellow; } .css-pkbazv { font-weight: bold; font-size: 20px; } </style>""", unsafe_allow_html=True)

Q: Casting `std::unique_ptr` Is there any problem in performing dynamic casting via the following function? template<typename Base, typename Derived> requires std::is_convertible_v<Derived&, Base&> && std::is_polymorphic_v<Base> inline std::unique_ptr<Derived> cast_to(std::unique_ptr<Base>&& ptr) { return std::unique_ptr<Derived>(dynamic_cast<Derived*>(ptr.release())); } A: Yes, your function can easily leak memory if the cast fails. Consider the following: struct Base { virtual ~Base() = default; }; struct Derived1 : Base {}; struct Derived2 : Base {}; int main() { std::unique_ptr<Base> bp = std::make_unique<Derived1>(); // bp does not point to a Derived2, so this cast will fail auto d2p = cast_to<Base, Derived2>(std::move(bp)); std::cout << bp.get() << '\n'; // 0 std::cout << d2p.get() << '\n'; // also 0; object was leaked } Demo From this snippet you can also see another small issue: because of the order of the template parameters you have to supply them both. You can't let the compiler deduce Base because it comes before Derived. With both of those issues in mind, the following would be a better implementation: template<typename Derived, typename Base> // swap the order of template parameters requires std::is_convertible_v<Derived&, Base&> && std::is_polymorphic_v<Base> inline std::unique_ptr<Derived> cast_to(std::unique_ptr<Base>&& ptr) { Derived* d = dynamic_cast<Derived*>(ptr.get()); if (d) { ptr.release(); return std::unique_ptr<Derived>(d); } return nullptr; // object is still owned by ptr } This fixes both of the above issues: int main() { std::unique_ptr<Base> bp = std::make_unique<Derived1>(); // No need to explicitly specify Base; the compiler can deduce that itself auto d2p = cast_to<Derived2>(std::move(bp)); std::cout << bp.get() << '\n'; // not 0; no leak std::cout << d2p.get() << '\n'; // 0 } Demo

Casting `std::unique_ptr`

Is there any problem in performing dynamic casting via the following function? template<typename Base, typename Derived> requires std::is_convertible_v<Derived&, Base&> && std::is_polymorphic_v<Base> inline std::unique_ptr<Derived> cast_to(std::unique_ptr<Base>&& ptr) { return std::unique_ptr<Derived>(dynamic_cast<Derived*>(ptr.release())); }

Q: Outlook Security, interop NET reference? I am attempting to create a standalone application that accesses Outlook email details. Specifically the Subject, Sender, and Body of the MailItem. I cannot for the life of me figure out why sometimes Outlook will prompt the user to allow access (as in, getting the "A program is trying to access email address information....Allow Access for x Minutes message box) and sometimes NOT. This irregularity is across different attempts at making an application over the weeks, so I am thinking that maybe there is something different with the references I am adding or object use? I have installed the Microsoft Office 2010 interop assemblies and adding the .NET reference of Microsoft.Office.Interop.Outlook version 14.0.0.0 Here is a very basic snippet of code that does cause the diaglog: using System; <br/> using System.Collections.Generic; <br/> using System.Linq; <br/> using System.Text; <br/> using Microsoft.Office.Interop.Outlook; <br/> namespace OutlookTest { class Program { static void Main(string[] args) { Microsoft.Office.Interop.Outlook.Application olApp = new Microsoft.Office.Interop.Outlook.Application(); Microsoft.Office.Interop.Outlook.NameSpace olNS = olApp.GetNamespace("MAPI"); MAPIFolder oFolder = olNS.GetDefaultFolder(OlDefaultFolders.olFolderInbox); foreach (object item in oFolder.Items) { if (item is MailItem) { MailItem i = (MailItem)item; Console.WriteLine("{0}", i.Body); } } Console.ReadLine(); } } } What am I doing wrong here? A: You dont do anything wrong, this is outlook security alert which is good for user/company. I had similar issue previous year. Options I remember so far: You can create a trusted microsoft addin as Remou mentioned or you can add yourself as trusted publisher or you can add a visual basic script into Outlook which you can call from your application. A: In the past, if Outlook did not detect an antivirus solution installed on the host machine, you would get the "Security Confirmation Prompt" on every code run. You would get it less if you had a commercial solution. This prompt still comes up today in Office 365, but you can suppress it by changing the "Programmatic Access Security" settings. Below is a before and after. Before, no "commercial" antivirus solution was installed on the host, initially we got the prompt on every code run. The prompt ceased to surface after we set Programmatic Access Security to "Never warn me about..." Once the commercial Antivirus Solution was installed the "Antivirus Status" showed up as "Valid".

Outlook Security, interop NET reference?

I am attempting to create a standalone application that accesses Outlook email details. Specifically the Subject, Sender, and Body of the MailItem. I cannot for the life of me figure out why sometimes Outlook will prompt the user to allow access (as in, getting the "A program is trying to access email address information....Allow Access for x Minutes message box) and sometimes NOT. This irregularity is across different attempts at making an application over the weeks, so I am thinking that maybe there is something different with the references I am adding or object use? I have installed the Microsoft Office 2010 interop assemblies and adding the .NET reference of Microsoft.Office.Interop.Outlook version 14.0.0.0 Here is a very basic snippet of code that does cause the diaglog: using System; <br/> using System.Collections.Generic; <br/> using System.Linq; <br/> using System.Text; <br/> using Microsoft.Office.Interop.Outlook; <br/> namespace OutlookTest { class Program { static void Main(string[] args) { Microsoft.Office.Interop.Outlook.Application olApp = new Microsoft.Office.Interop.Outlook.Application(); Microsoft.Office.Interop.Outlook.NameSpace olNS = olApp.GetNamespace("MAPI"); MAPIFolder oFolder = olNS.GetDefaultFolder(OlDefaultFolders.olFolderInbox); foreach (object item in oFolder.Items) { if (item is MailItem) { MailItem i = (MailItem)item; Console.WriteLine("{0}", i.Body); } } Console.ReadLine(); } } } What am I doing wrong here?

Q: Plotly imshow reversing y labels reverses the image I'd like to visualize a 20x20 matrix, where top left point is (-10, 9) and lower right point is (9, -10). So the x is increasing from left to right and y is decreasing from top to bottom. So my idea was to pass x labels as a list: [-10, -9 ... 9, 9] and y labels as [9, 8 ... -9, -10]. This worked as intended in seaborn (matplotlib), however doing so in plotly just reverses the image vertically. Here's the code: import numpy as np import plotly.express as px img = np.arange(20**2).reshape((20, 20)) fig = px.imshow(img, x=list(range(-10, 10)), y=list(range(-10, 10)), ) fig.show() import numpy as np import plotly.express as px img = np.arange(20**2).reshape((20, 20)) fig = px.imshow(img, x=list(range(-10, 10)), y=list(reversed(range(-10, 10))), ) fig.show() Why is this happening and how can I fix it? EDIT: Adding seaborn code to see the difference. As you can see, reversing the range for labels only changes the labels and has no effect on the image whatsoever, this is the effect I want in plotly. import seaborn as sns import numpy as np img = np.arange(20**2).reshape((20, 20)) sns.heatmap(img, xticklabels=list(range(-10, 10)), yticklabels=list(range(-10, 10)) ) import seaborn as sns import numpy as np img = np.arange(20**2).reshape((20, 20)) sns.heatmap(img, xticklabels=list(range(-10, 10)), yticklabels=list(reversed(range(-10, 10))) ) A: To get the desired visualization in plotly, you will need to specify the x and y values manually. Instead of passing in the labels as a list, you should specify the x and y values as a list of tuples, like so: x = [(-10, 9), (-9, 8), ... (9, -10)] y = [(-10, 9), (-9, 8), ... (9, -10)] This should produce the desired visualization. A: As I mentioned in my comment, the internal representation of px.imshow() is a heatmap. I coded your objective with a heatmap in a graph object. I didn't change this for any clear reason, I just took a different approach because I couldn't achieve it with px.imshow(). import plotly.graph_objects as go img = np.arange(20**2).reshape((20, 20)) fig = go.Figure(data=go.Heatmap(z=img.tolist()[::-1])) fig.update_yaxes(tickvals=np.arange(0, 20, 1), ticktext=[str(x) for x in np.arange(-10, 10, 1)]) fig.update_xaxes(tickvals=np.arange(0, 20, 1), ticktext=[str(x) for x in np.arange(-10, 10, 1)]) fig.update_layout(autosize=False, height=500, width=500) fig.show() A: It looks like the issue is that the y values in the px.imshow() function are being interpreted as the actual y-values for the data points in your matrix, rather than labels for the y-axis. Therefore, when you provide y=list(reversed(range(-10, 10))), the y-values of your data points are being reversed, resulting in the vertical reversal of the image. One way to fix this is to use the yaxis_title argument in the px.imshow() function to specify the title for the y-axis, and then use the tickvals and ticktext arguments to specify the values and labels for the y-axis ticks, respectively. For example: import numpy as np import plotly.express as px img = np.arange(20**2).reshape((20, 20)) y_values = list(range(-10, 10)) fig = px.imshow(img, x=list(range(-10, 10)), yaxis_title="y-axis", tickvals=y_values, ticktext=reversed(y_values), ) fig.show() This should produce an image where the y-axis labels are in the correct order, without reversing the image.

Q: Unuderstanding testbenching of Lattice Semiconductor IP verilog modules - MIPI CSI2-DPHY module My development environment is from Lattice Semiconductor EDA (Radiant Software).

Q: Throttling threads in C# I have a situation where I am doing WebAPI calls to a service which sometimes cannot keep up with the load. I'm keeping track of how long the WebAPI takes to respond and how many active threads I have, and when the WebAPI is taking long to respond I want to limit the number of concurrent calls to a specific number (which I'd save in a config). What I was thinking was of using SemaphoreSlim but the problem would be that at that time the number of concurrent threads would most likely be greater than the number I'm limiting to. Is there a neat way of tackling this problem that wouldn't involve reinventing the wheel? A: I have created a library that does just that. It's called SemaphoreSlimThrottling and is available on GitHub and NuGet. Suppose you had 11 concurrent threads and wanted to limit them to 10. SemaphoreSlim doesn't allow you to initialize with an initialCount of -1 (i.e. you need to release 2 before a new one can enter), but with SemaphoreSlimThrottle you can. var mySemaphore = new SemaphoreSlimThrottle(-1, 10); A: One way to solve this problem is to use a SemaphoreSlim object to limit the number of concurrent threads that can access a critical section of code. When a thread wants to enter the critical section, it can call the Wait() method on the SemaphoreSlim object. If the number of threads that are currently in the critical section is less than the maximum number allowed, the thread will be granted access to the critical section and the SemaphoreSlim's internal count will be decremented by 1. Otherwise, the thread will be blocked until another thread leaves the critical section and the SemaphoreSlim's count is incremented. When a thread leaves the critical section, it should call the Release() method on the SemaphoreSlim object to increment the count and potentially unblock another thread that is waiting to enter the critical section. Here is an example of how you could use a SemaphoreSlim object to limit the number of concurrent threads that can access a critical section of code: // Create a SemaphoreSlim object with a maximum count of 10. // This means that at most 10 threads can be in the critical section at the same time. SemaphoreSlim semaphore = new SemaphoreSlim(10); // This is the critical section of code that we want to limit access to. void MakeWebApiCall() { // Acquire a lock on the semaphore. // If the number of threads in the critical section is already at the maximum allowed, // this thread will be blocked until another thread leaves the critical section. semaphore.Wait(); try { // Make the WebAPI call here. // Note that only 10 threads can be in this section of code at the same time. } finally { // Release the lock on the semaphore. // This will increment the semaphore's count and potentially unblock another thread // that is waiting to enter the critical section. semaphore.Release(); } }

Q: Restrict typescript to insure reference to 'any' object's properties is checked I have a JS object myObject, which is of type any (I can't change the type, since it comes from a library). If I try to access a property from myObject I get no errors from typescript, since its type is any. But myObject could be undefined, and cause a crash. Is it possible to get typescript to give an error in this case? For example: console.log(myObject.myProperty) // <-- if myObject is undefined, this will crash. What I would like: console.log(myObject.myProperty) // <-- typescript gives error console.log(myObject?.myProperty) // <-- typescript gives no error Is there a tsconfig for changing this behavior? I am not looking for a solution using type unknown. A: No, TypeScript does not have support for a stricter interpretation of the any type in which member access is disallowed unless it is known to be safe. Nor have I found any existing request for this particular feature. There was a proposal for a --strictAny, which would have been different, but this was eventually closed in microsoft/TypeScript#24737 saying, among other things, that extra complexity around any really didn't seem to be worth it, especially because there are many places in real world code where any is intentionally used as a way to turn off type checking. So it is unlikely that TypeScript will add such functionality. Instead, you could use a linter, like TypeScript ESLint. There is a no-unsafe-member-access rule which "disallows member access on any variable that is typed as any". This will cause the desired error to appear, but it will also cause undesired errors where you have done the proper type check. That is, it is more restrictive than you want: declare const myObject: any; myObject.myProperty // warning: unsafe access myObject?.myProperty // warning: unsafe access ☹ It doesn't look like there's any "perfect" way to proceed. I'd recommend that you copy the value to a variable of a non-any type: type MyAny = { [k: string]: any } | undefined | null; const _myObject: MyAny = myObject _myObject.myProperty; // error _myObject?.myProperty; // okay Or write a type checking function that narrows any to more safely indexable type: function nonNullish(x: any): x is { [k: string]: any } { return x != null; } if (nonNullish(myObject)) { myObject.myProperty // okay } Or maybe even push back on the typings provider for the library and say that any is too loose of a type if the value might really be undefined or null at runtime. (If it can't, then the other option is to just stop worrying about it until and unless it does happen.) TS-ESLint Playground link to code

Q: Why are some properties of my Firebase database undefined? When my character card component loads I receive the below error. TypeError: Cannot read properties of undefined (reading 'attack') The main thing that confuses me is that the character name(userData.name) and profile image(userData.icon) are not undefined. All properties are stored in the same Firebase database. I can't figure out why 2 out of the 4 properties I'm trying to access are undefined. I get the same error if trying to access the defense level.

I have a feeling that I'm missing something pretty basic. Repo is public at https://github.com/nschroder26/idleWeb if more context is needed. A: I read your code. There are 3 problems with your code. The initial value of userData should be an empty object not an array. You should check if userData is set and then render your UI. You wrote your onValue function in useEffect without any dependency. It means that it runs only once. At that time, auth.currentUser is undefined so userId is undefined too. So you get null for the user data. In order to fix the issue, you should write your logic inside onAuthStateChanged. This will fix your problem: import { Fragment, useState, useEffect } from "react"; import { auth } from "../../components/Utils/firebase"; import { getDatabase, onValue, ref } from "firebase/database"; import CharCard from "../../components/CharCard/charCard"; import { onAuthStateChanged } from "firebase/auth"; const Character = () => { const db = getDatabase(); const [userData, setUserData] = useState({}); //caputures current user from firebase db useEffect(() => { onAuthStateChanged(auth, (currentUser) => { if(currentUser) { const userId = currentUser.uid; const userRef = ref(db, "/Users/" + userId); onValue(userRef, (snapshot) => { const data = snapshot.val(); setUserData(data); console.log(data) }); } }) }, []); return ( <Fragment> <CharCard name={userData?.name} icon={userData?.icon} attack={userData?.skills?.attack?.level} defense={userData?.skills?.defense?.level} /> </Fragment> ); }; export default Character;

Q: Why does this code bit work in clion but doesn't in VS Hi I copied the following code from my linux machine with clion running. But in VS on Windows it seems to cause problems entry_t* find_entry( char* n ) { // TODO (2) int x = strlen(n); char str[x]; for (size_t i = 0; i < strlen(str); i++) { str[i] = toupper(n[i]); } n = &str; for (size_t i = 0; i < list_length; i++) { if (strcmp(n, name_list[i].name) == 0) { return &name_list[i]; } } } VS underlines the x in char str[x]; before the statement do find x was in the brackets of str. I thought finding the length first in another variable would solve the problem VS give the following error Schweregrad Code Beschreibung Projekt Datei Zeile Unterdrückungszustand Fehler (aktiv) E0028 Der Ausdruck muss einen Konstantenwert aufweisen. Names.exe - x64-Debug C:\Users\Eyüp\source\repos\09\main.c 102 trying my best to translate it -> Error(active) E0028 Statement needs to be a constant value A: Your code invokes undefined behaviour: as you do not null terminate the string you call strlen on not null terminated (and initially not initialized string) The logic is also wrong. entry_t* find_entry( const char* n ) { // TODO (2) size_t x = strlen(n); char str[x + 1]; for (size_t i = 0; i <= x; i++) { str[i] = toupper((unsigned char)n[i]); } str[x] = 0; for (size_t i = 0; i < list_length; i++) { if (strcmp(str, name_list[i].name) == 0) { return &name_list[i]; } } return NULL; } You need to return something if the sting was not found. To use VLAs in VS How to use Visual Studio as an IDE with variable length array(VLA) working? A: Variable-length arrays (i.e. arrays whose size is not known at compile-time) are not supported in MSVC because they don't care. Hence you need to use malloc and friends instead. However that is not the only problem in your code: it has multiple undefined behaviours. Here is a suggested fix: entry_t* find_entry( char* n ) { // return value of strlen is of type size_t, not int size_t x = strlen(n); // [x] was wrong, it needs to be [x + 1] for the null terminator! char *str = malloc(x + 1); // do not use strlen again in the loop. In worst case it does need // to go through the entire string looking for the null terminator every time. // You must copy the null terminator, hence i <= x or i < x + 1 for (size_t i = 0; i <= x; i++) { // the argument of toupper needs to be *unsigned char* str[i] = toupper((unsigned char)n[i]); } // why this did even exist? And it has type error anyway // n = &str; for (size_t i = 0; i < list_length; i++) { if (strcmp(str, name_list[i].name) == 0) { // need to free the str... free(str); return &name_list[i]; } } // in both paths... free(str); // add default return value return NULL; }

Q: Reverse string using .as_bytes() I'm trying to reverse a string. I use the solution of this post and it works. But I would like to try with bytes instead of grapheme clusters as shown below: pub fn reverse2(input: &str) -> String { let s: String = input .as_bytes() .iter() .rev() .collect(); return s; } Unfortunately, I can't run the function collect() after rev(). I don't know which method to use. How would you do it ? A: As you explicitly ask about not using chars(), you have to restrict yourself to ASCII strings. pub fn reverse2(input: &str) -> String { // Reversing on byte-level only works with ASCII strings. assert!(input.is_ascii()); let reversed_bytes: Vec<u8> = input.as_bytes().iter().copied().rev().collect(); let reversed_string = unsafe { // SAFETY: This is guaranteed to be a valid UTF8 string, because: // - the input string is a valid ASCII string // - a reversed ASCII string is still a valid ASCII string // - an ASCII string is a valid UTF8 string String::from_utf8_unchecked(reversed_bytes) }; return reversed_string; } You can also use the checked version, if you don't like the unsafe, but it comes with a little bit of overhead: pub fn reverse2(input: &str) -> String { // Reversing on byte-level only works with ASCII strings. assert!(input.is_ascii()); let reversed_bytes: Vec<u8> = input.as_bytes().iter().copied().rev().collect(); let reversed_string = String::from_utf8(reversed_bytes).unwrap(); return reversed_string; } Optimization: Checking is_ascii() is some overhead. It is not strictly required, however. UTF-8 has one special property: every non-ASCII byte is valued 128 and above. So technically it is enough to just simply filter out all values equal to or above 128: pub fn reverse2(input: &str) -> String { let reversed_bytes: Vec<u8> = input .as_bytes() .iter() .rev() .map(|&val| { if val < 128 { val } else { 0x1a // replacement char } }) .collect(); let reversed_string = unsafe { // SAFETY: This is guaranteed to be a valid UTF8 string, because: // - `reversed_bytes` is guaranteed to be an ASCII string // - an ASCII string is a valid UTF8 string String::from_utf8_unchecked(reversed_bytes) }; return reversed_string; } fn main() { let s = "abcdefghij"; println!("{:?}", s.as_bytes()); let reversed = reverse2(s); println!("{}", reversed); println!("{:?}", reversed.as_bytes()); } [97, 98, 99, 100, 101, 240, 159, 152, 131, 102, 103, 104, 105, 106] jihgfedcba [106, 105, 104, 103, 102, 26, 26, 26, 26, 101, 100, 99, 98, 97] Additional remark: Consider using .bytes() instead of .as_bytes().iter(). A: To fix this code, you can use the .chars() method on the input string to return an iterator of the characters in the string instead of the bytes. Then you can use the .collect() method to create a new string with the reversed characters: pub fn reverse2(input: &str) -> String { let s: String = input .chars() .rev() .collect(); return s; } This will properly reverse the characters in the input string and return the new reversed string. A: Well, firstly you should use .bytes() instead of .as_bytes().iter(). Secondly, you need to reverse characters, not bytes, cuz a &str may contain UTF-8, so use .chars() instead of .bytes(). Thirdly, you don’t need to collect it into a variable and return a variable, just return the result of collecting. Fourthly, you don’t need explicit return. Let’s sum all the stuff i said: pub fn reverse2(input: &str) -> String { input.chars() .rev() .collect() } A: Here is a solution that converts the input string into a byte vector ─ so the reverse function of Vec can be used: pub fn reverse2(input: &str) -> String { let v = &mut input.to_string().into_bytes(); v.reverse(); std::str::from_utf8(v).unwrap().to_string() } The input string may only contain ASCII characters. Playground

I don't know enough flutter on a technical level but what fixed it for me was changing the root widget of the web page to a Scaffold . A: I had the same issue using FlutterFlow.io and using a Custom Widget on a page. FlutterFlow exposes a widget property: "Enforce width & Height". When this property is set, FlutterFlow generates the code for a new Container and places the Custom Widget in that container. Which means that Custom Widget I was using was causing a lot of screen overflow errors w/o this new Container. So it seems that this error is caused by Flutter not being able to figure out how to bound the widget (?). Add a container and see...

Q: HAProxy SSL termination: how to resolve certificate error only experienced by WAN clients? My HAProxy SSL termination setup works exactly as expected for LAN clients, but if I use a WAN client (e.g. Tor Browser) I get a certificate error. Yet, they can bypass my 80->443 redirect and access my server on port 80 if I provide a firewall rule allowing access to port 80. How can I ensure WAN clients connect with HTTPS? My front end is configured to use my wildcard certificate, *.example.com, with a rule which routes requests to the correct backend server. I also have a frontend redirect from port 80 to 443. The system work exactly as I expect for clients on my home network: when visiting subdomain.example.com in a browser: all subdomain.example.com:80 requests are forwarded to subdomain.example.com443 HAproxy frontend performs SSL offloading the client is connected to the backend server 192.168.1.50:80 via HTTPS as I expected. However, when I try to connect to my subdomain from outside my local network, e.g. subdomain.example.com:443 using TOR browser, I receive a "Secure Connection Failed" message, with "Error code: SSL_ERROR_RX_RECORD_TOO_LONG". If I create a firewall rule allowing access to port 192.168.1.50:80, I can change the Tor Browser to HTTP mode and then connect to my backend server in an unsecured way. But, I don't understand how this is possible. I expect at least that the http redirect I created in the HAProxy frontend would be respected. How could an outside client can bypass my HAProxy front end redirect? I assume whatever is happening here is also related to the outside client not establishing a secure connection with my HAProxy front end. A: I've solved my issue. Here is what I did: Create a virtual IP (Firewall --> Virtual IPs --> Add)\ IP Alias --> WAN --> Single Address (I picked an address that wasn't in use, like 192.168.1.XXX) Saved with description "HAProxy Frontend Virtual IP" Opened port 443 in the Firewall, specifying access to 192.168.1.XXX Services --> HAProxy. Here I duplicated my front end, and under "Listen Address" I changed from "WAN" to 192.168.1.XXX (HAProxy Frontend Virtual IP) Now I can access my server via a Tor connection (or any other external client) without issue. I still don't understand exactly what was happening before and what is happening now. I assume there was some conflict since HAProxy was listening on the same address as pfSense (my WAN IP address).

Q: How can I make the movement faster if I press the key? I'm making a Tetris game now. I want to implement it so that if I press the down key , the block falls quickly, and if I press the left and right keys, the block moves quickly. Pressing the key used the pygame.key.get_pressed() function and used pygame.time.set_timer() function to make speed change. The game speed was set to 600 for the interval of pygame.time.set_timer(), but if I press the down key, the block drops quickly because the interval was set to 150 to speed up the game so that the block drops quickly. The problem is to implement the function on the left and right direction keys. It is also possible to move the left and right keys quickly if I change the interval. The problem is that the pygame.time.set_timer() function changes the speed of the entire game, so the block falls quickly as well as the left and right movements of the block. Is there a way to speed up left and right movements without touching the speed of other things? I'd appreciate it if you let me know, thanks! code elif start: for event in pygame.event.get(): attack_stack = 0 pos = pygame.mouse.get_pos() if event.type == QUIT: done = True elif event.type == USEREVENT: # Set speed if not game_over: keys_pressed = pygame.key.get_pressed() # Soft drop if keys_pressed[K_DOWN]: pygame.time.set_timer(pygame.USEREVENT, 100) elif keys_pressed[K_RIGHT]: pygame.time.set_timer(pygame.USEREVENT, 100) if not is_rightedge1(dx, dy, mino_en, rotation, matrix): ui_variables.move_sound.play() dx += 1 elif keys_pressed[K_LEFT]: pygame.time.set_timer(pygame.USEREVENT, 100) if not is_leftedge1(dx, dy, mino_en, rotation, matrix): ui_variables.move_sound.play() dx -= 1 else: pygame.time.set_timer(pygame.USEREVENT, 600) A: It looks to me that the reason your piece is dropping faster when you press a button is because if the user doesn't press a button the timer is set to 600ms. If they do press a button then the timer is set to 100ms. As for how to fix this, you'll need to decouple the downward piece movement and user-input movement. I'd suggest making another event that only handles downward movement. DROPEVENT = pygame.USEREVENT + 1 elif event.Type == DROPEVENT: pygame.time.set_timer(DROPEVENT, 600) # Your piece drop logic. This snippet is not complete nor tested at all, but I hope it get the idea across. You don't seem to have posted the logic that handles dropping the piece, but you would need to move this into the new event. A: Waiting a long time (100 ms is already long) before reacting to user input feels bad, so you don’t want to wait a full piece-movement time before checking for input again just because there is none at the moment you check. Instead, poll for input at a steady pace of (say) 30 Hz; for simplicity, the usual approach is to just run the whole game at that frequency even if nothing needs to change on the screen for some (or even most) frames. (This technique also naturally allows smooth animations of or between piece movements.) The usual implementation of “nothing” on a frame is to adjust the piece’s position every frame but integer-divide that position by some constant before using it for anything other than keeping track of its progress toward the next movement (like drawing it or checking for collisions). You might use pixels as the “invisible unit” when movement must be by whole tiles; games where sprites can be drawn at any pixel divide each into some convenient number of subpixels in the same fashion.

Q: React/JS: Click on a btn without triggering div click not working as expected codesandbox: https://codesandbox.io/s/currying-breeze-depdc9?file=/package.json I have a Card component that has 4 potential states: "active", "selected", "discarded", "complete". Depending on the state, I need to display a different css class. The states are set by clicking on specific parts of the card and each part is a "toggle" (one click sets it, another click "unsets" it): default state is active, if the user click anywhere on the card, it gets "selected" and two buttons appear inside the card ("back", "discard"). if the user clicks on "back", I need to toggle the state bac to "active". if the user clicks on "discard" I need to set the state to "discarted" The state is stored at the "App" level and I am passing it to the component through props. This means that for updating the states I am passing some "handler" from the app to the component (SelectCard, DiscardCard) Here below is my code. I am able to toggle the "active"-->"select"-->"active" through the function SelectCard. However, I am doing something wrong since I can't manage to get the click on "discard" to actually call the DiscardCard function. My feeling is that it has something to do with the fact that the btn is inside the div and I have an "onClic" for the div that calls SelectCard so when I click on the "discard btn" it's like I am clicking into the div as well and things don't work out.

Then, as mentioned in the other question, you need to actually run the handler you passed. And in order to call a handler in a block of code you need to add () after its name. So for the Back you need onClick={ props.item.selected ? (e) => { e.stopPropagation(); props.onPress(); } : undefined } and for Discard you want onClick={(e) => { e.stopPropagation(); props.onDiscard(); }} Demo at https://codesandbox.io/s/competent-swartz-d05x9y

React/JS: Click on a btn without triggering div click not working as expected

codesandbox: https://codesandbox.io/s/currying-breeze-depdc9?file=/package.json I have a Card component that has 4 potential states: "active", "selected", "discarded", "complete". Depending on the state, I need to display a different css class. The states are set by clicking on specific parts of the card and each part is a "toggle" (one click sets it, another click "unsets" it): default state is active, if the user click anywhere on the card, it gets "selected" and two buttons appear inside the card ("back", "discard"). if the user clicks on "back", I need to toggle the state bac to "active". if the user clicks on "discard" I need to set the state to "discarted" The state is stored at the "App" level and I am passing it to the component through props. This means that for updating the states I am passing some "handler" from the app to the component (SelectCard, DiscardCard) Here below is my code. I am able to toggle the "active"-->"select"-->"active" through the function SelectCard. However, I am doing something wrong since I can't manage to get the click on "discard" to actually call the DiscardCard function. My feeling is that it has something to do with the fact that the btn is inside the div and I have an "onClic" for the div that calls SelectCard so when I click on the "discard btn" it's like I am clicking into the div as well and things don't work out.

I need quick help because im making a program. I was trying to do that on many possible ideas, and I don't know how to compile these, can you give me it scripted fully, with vbInformation, vbYes and vbNo? (Remember, if yes is pressed, it runs file, and if no is pressed, it closes it) You can still give me that scripted, even in other file extension. A: Try this : result = MsgBox ("Yes or No?", vbYesNo, "Yes No Example") Select Case result Case vbYes MsgBox("You chose Yes") Dim objShell Set objShell = Wscript.CreateObject("WScript.Shell") objShell.Run "TestScript.vbs" Set objShell = Nothing Case vbNo MsgBox("You chose No") End Select

I tried also like this but it gives me the same error for (let funnelStageKey in Object.keys(overall) as Array<keyof typeof FunnalStage>) { const count = overall[funnelStageKey].count; console.log(count); } LINK TO PLAYGROUND A: You can use the Object.entries method to iterate over the properties of the overall object. You can then destructure the key/value pairs in the for-of loop and use the key to access the corresponding enum value: for (const [key, value] of Object.entries(overall)) { console.log(FunnelStage[key], value.count); } Or, you can use the Object.keys method to get an array of keys, and then use the map method to create a new array of FunnelStage values: const keys = Object.keys(overall); const funnelStages = keys.map(key => FunnelStage[key]); You can then iterate over the funnelStages array and use the values to access the corresponding properties in the overall object: for (const funnelStage of funnelStages) { console.log(funnelStage, overall[funnelStage].count); }

Q: Why do I get "Pickle - EOFError: Ran out of input" reading an empty file? I am getting an interesting error while trying to use Unpickler.load(), here is the source code: open(target, 'a').close() scores = {}; with open(target, "rb") as file: unpickler = pickle.Unpickler(file); scores = unpickler.load(); if not isinstance(scores, dict): scores = {}; Here is the traceback: Traceback (most recent call last): File "G:\python\pendu\user_test.py", line 3, in <module>: save_user_points("Magix", 30); File "G:\python\pendu\user.py", line 22, in save_user_points: scores = unpickler.load(); EOFError: Ran out of input The file I am trying to read is empty. How can I avoid getting this error, and get an empty variable instead? A: Most of the answers here have dealt with how to mange EOFError exceptions, which is really handy if you're unsure about whether the pickled object is empty or not. However, if you're surprised that the pickle file is empty, it could be because you opened the filename through 'wb' or some other mode that could have over-written the file. for example: filename = 'cd.pkl' with open(filename, 'wb') as f: classification_dict = pickle.load(f) This will over-write the pickled file. You might have done this by mistake before using: ... open(filename, 'rb') as f: And then got the EOFError because the previous block of code over-wrote the cd.pkl file. When working in Jupyter, or in the console (Spyder) I usually write a wrapper over the reading/writing code, and call the wrapper subsequently. This avoids common read-write mistakes, and saves a bit of time if you're going to be reading the same file multiple times through your travails A: I would check that the file is not empty first: import os scores = {} # scores is an empty dict already if os.path.getsize(target) > 0: with open(target, "rb") as f: unpickler = pickle.Unpickler(f) # if file is not empty scores will be equal # to the value unpickled scores = unpickler.load() Also open(target, 'a').close() is doing nothing in your code and you don't need to use ;. A: It is very likely that the pickled file is empty. It is surprisingly easy to overwrite a pickle file if you're copying and pasting code. For example the following writes a pickle file: pickle.dump(df,open('df.p','wb')) And if you copied this code to reopen it, but forgot to change 'wb' to 'rb' then you would overwrite the file: df=pickle.load(open('df.p','wb')) The correct syntax is df=pickle.load(open('df.p','rb')) A: As you see, that's actually a natural error .. A typical construct for reading from an Unpickler object would be like this .. try: data = unpickler.load() except EOFError: data = list() # or whatever you want EOFError is simply raised, because it was reading an empty file, it just meant End of File .. A: You can catch that exception and return whatever you want from there. open(target, 'a').close() scores = {}; try: with open(target, "rb") as file: unpickler = pickle.Unpickler(file); scores = unpickler.load(); if not isinstance(scores, dict): scores = {}; except EOFError: return {} A: if path.exists(Score_file): try : with open(Score_file , "rb") as prev_Scr: return Unpickler(prev_Scr).load() except EOFError : return dict() A: I have encountered this error many times and it always occurs because after writing into the file, I didn't close it. If we don't close the file the content stays in the buffer and the file stays empty. To save the content into the file, either file should be closed or file_object should go out of scope. That's why at the time of loading it's giving the ran out of input error because the file is empty. So you have two options : file_object.close() file_object.flush(): if you don't wanna close your file in between the program, you can use the flush() function as it will forcefully move the content from the buffer to the file. A: Had the same issue. It turns out when I was writing to my pickle file I had not used the file.close(). Inserted that line in and the error was no more. A: Note that the mode of opening files is 'a' or some other have alphabet 'a' will also make error because of the overwritting. pointer = open('makeaafile.txt', 'ab+') tes = pickle.load(pointer, encoding='utf-8') A: temp_model = os.path.join(models_dir, train_type + '_' + part + '_' + str(pc)) # print(type(temp_model)) # <class 'str'> filehandler = open(temp_model, "rb") # print(type(filehandler)) # <class '_io.BufferedReader'> try: pdm_temp = pickle.load(filehandler) except UnicodeDecodeError: pdm_temp = pickle.load(filehandler, fix_imports=True, encoding="latin1") A: This error comes when your pickle file is empty (0 Bytes). You need to check the size of your pickle file first. This was the scenario in my case. Hope this helps!

Q: Accessing variable template using decltype A minimized example of my code showing the problem: #include <cassert> #include <iostream> #include <map> #include <string> template <typename T> const std::map<std::string, T> smap; template <> const std::map<std::string, bool> smap<bool>{{"a", false}}; int main() { std::map<bool, std::string> rmap{{false, "x"}}; for (const auto& [key, val] : rmap) { std::cerr << typeid(bool).hash_code() << "\n"; std::cerr << typeid(decltype(key)).hash_code() << "\n"; std::cerr << smap<bool>.size() << "\n"; std::cerr << smap<decltype(key)>.size() << "\n"; assert((std::is_same_v<bool, decltype(key)>)); } return 0; } Godbolt It gives the output: 10838281452030117757 10838281452030117757 1 0 example.cpp:22: int main(): Assertion `(std::is_same_v<bool, decltype(key)>)' failed. Why is it that I can't access the variable template using decltype when it's referring to the same type (bool)? For the record I also tried to not use structured binding and using decltype on first in the pair with the same result. However if I create an actual bool variable, like so ... bool b; std::cerr << settings_map<decltype(b)>.size() << "\n"; ... it's working. A: the value_type is std::pair<const Key, T>, so decltype(key) is const bool, not bool and you capture it by const auto& so it's const anyway typeid remove all cvref qualifiers, that's why you get same hash_code as a side note, hash_code is a hash and no guaranteed on they would not collide, you can use operator== to check type equality. A: Keys are const so you'll need to remove it to make the assertion pass. assert((std::is_same_v<bool, std::remove_cv_t<decltype(key)>>)); A: decltype(key) is const bool, not bool. And typeid strips const qualifiers, so the two have the same (runtime) representation. If the type of type or expression is cv-qualified, the result of the typeid refers to a std::type_info object representing the cv-unqualified type (that is, typeid(const T) == typeid(T)). So while typeid treats the two types as equivalent, template expansion (and is_same_v) does not, and you get two different maps: one for bool and one for const bool. Note that the assertion assert((std::is_same_v<const bool, decltype(key)>)); succeeeds if put in place of the one in your code. To remove cv-qualifiers, use remove_cv_t. std::cerr << settings_map<std::remove_cv_t<decltype(key)>>.size() << "\n"; In your last snippet bool b; std::cerr << settings_map<decltype(b)>.size() << "\n"; The b is not constant, so decltype(b) is actually bool, not const bool.

Q: Update only the chunks that have changed with Webpack.watch()? I have a webpack build that utilizes the watch() method to continuously rebuild my javascript as I work. I also have a watcher that uploads changed JS files to a remote server. Right now when I change ANY file, it recompiles ALL files. So even if one chunk changed, it will update everything, including my vendor file and other unrelated bundles, chunks, etc. Is there a way in Webpack to only recompile the files that changed and have dependencies that were changed? Here's an example of my webpack build code: var compiler = webpack(require('./webpack.config.js')); compiler.watch({ aggregateTimeout: 300, // wait so long for more changes poll: true }, function(err, stats) { console.log(stats); }); A: Yes, can do this by using the optimization.moduleIds option in your webpack configuration. The optimization.moduleIds option allows you to specify the method that webpack should use to generate module IDs for module identification in the generated code. By default, webpack uses the natural module ID generation method, which assigns a unique ID to each module based on its location in the file system. This means that whenever the file system structure changes, all module IDs will be regenerated, even if the module content has not changed. If you want to only recompile the changed modules and their dependencies, you can use the named or hashed module ID generation methods. These methods generate module IDs based on the module name or the module content hash, respectively, so they will not change unless the module content itself changes. Here is an example of how you can configure webpack to use the named module ID generation method: module.exports = { // ... optimization: { moduleIds: 'named' } }; With this configuration, webpack will only recompile the changed modules and their dependencies when you use the watch method.

Q: Converting a BigInteger to a string in some base: speed issue (Kotlin) I want to convert large positive BigIntegers (up to many thousands of digits) to strings in Kotlin, using number bases up to 100 (and possibly higher). For bases ≤36, there is of course toString(base), but for larger bases, I wrote this extension function: fun BigInteger.toStringX(base: Int): String { if (base <= 36) return toString(base) // improve speed if base <= 36 val bigBase = base.toBigInteger() var n = this val stringBuilder = StringBuilder() while (n > ZERO) { val div = n.divideAndRemainder(bigBase) stringBuilder.append(DIGITS[div[1].toInt()]) n = div[0] } return stringBuilder.reverse().toString() } where DIGITS is a string containing the list of digits. Now the native toString is faster by about an order of magnitude than my function – e.g. 60 ms for about 10,000 digits vs. 500 ms. Why is my function so slow? Any help improving on its speed (while maintinaing the ability to convert to bases > 36) would be appreciated. (By the way, replacing append() with insert() and losing reverse() in the last line doesn't change much.) A: Looking at the source code for the built-in toString, it seems to call this private toString, which implements a divide-and-conquer algorithm. /** * Converts the specified BigInteger to a string and appends to * {@code sb}. This implements the recursive Schoenhage algorithm * for base conversions. This method can only be called for non-negative * numbers. * <p> * See Knuth, Donald, _The Art of Computer Programming_, Vol. 2, * Answers to Exercises (4.4) Question 14. * * @param u The number to convert to a string. * @param sb The StringBuilder that will be appended to in place. * @param radix The base to convert to. * @param digits The minimum number of digits to pad to. */ private static void toString(BigInteger u, StringBuilder sb, int radix, int digits) { ... results = u.divideAndRemainder(v); int expectedDigits = 1 << n; // Now recursively build the two halves of each number. toString(results[0], sb, radix, digits - expectedDigits); toString(results[1], sb, radix, expectedDigits); } This means that there is only O(log(N)) divisions, for an N-bit number. Compare this to your algorithm, which does O(N) divisions. So for large numbers, you can implement this algorithm too - "split" the number up into smaller ones, then use your O(N) algorithm when they are small enough, all the while passing the string builder along, so the digits are appended.

Q: SCNScene initialization from file crashes on macOS Ventura This is pretty unusual, because I'm unable to replicate the issue on macOS Monterey. I have a SCNScene object that is initialized in viewDidLoad as such: scene = SCNScene(named: "art.scnassets/preview.scn")! And as you can see below, the file exists in my project's Resources under the appropriate path: As previously mentioned, the crash does not occur in builds created under macOS Monterey. Did something change in the resource file path's API? So far I have tried to initialize using a different way of creating the URL, like so: scene = try! SCNScene(url: Bundle.main.url(forResource: "art.scnassets/preview", withExtension: "scn")!) A: 1. Reset the path to Command Line Tools To fix this issue, install the latest version of Command_Line_Tools for Xcode 14.1 and then execute these two commands in zsh Terminal (password is required): sudo xcode-select --reset sudo xcode-select -switch /Library/Developer/CommandLineTools Restart your Mac. 2. Renaming process Rename the art.scnassets to artist.scnassets if the above steps still do not help.

After scraping the data I am getting results as shown below:- But I want to get the name of each medicine in a single row and all details associated with that medicine under different columns. Something like this. I tried using explode, and transform and also searched over the internet and stack overflow but was unable to convert this into the expected format. A: It looks like you are appending the values to the list within the try block, which means that if an exception occurs, the list will not be updated. Instead, you should append the values to the list outside of the try block, and use a default value within the except block. For example, instead of this: try: med_name = [] for i in driver.find_elements(By.XPATH,"//div[@id='brand_dose']//div[@class='product-name']"): med_name.append(i.text) except: med_name.append(None) You can do this: med_name = [] try: for i in driver.find_elements(By.XPATH,"//div[@id='brand_dose']//div[@class='product-name']"): med_name.append(i.text) except: med_name.append(None) This way, the med_name list will always be updated, whether or not an exception occurs. To achieve the expected output, you can simply use the extend method to add the elements of the lists to the data list, instead of creating a dictionary and appending that to the data list. For example, instead of this: data.append({ 'Medicine_name':med_name, 'Manufacture_name':manuf_name, 'Product_Counry':country, 'Prescription_Required':pres_req, 'Product_Details':str_price}) You can do this: data.extend(zip(med_name, manuf_name, country, pres_req, str_price)) This will create a list of tuples, where each tuple contains the values of the corresponding elements from the med_name, manuf_name, country, pres_req, and str_price lists. This will give you the desired output, where each medicine's details are on a separate row.

Q: Timeseries - group data by specific time period slices I am working with a csv file that has a dataset of 13 years worth of 5m time intervals. I am trying to slice sections of this dataset into specific time periods. example time_period = (df['time'] >= '01:00:00') & (df['time']<='5:00:00') time_period_df = df.loc[time_period] I would expect an output of only the time between 1-5 to be included in this time period, however, I am getting all 24hrs in the output I would like the output to print only time in between and including 1:00:00 and 5:00:00. A: It looks like you are using the comparison operators >= and <= to try and specify the time range you want to include in your time period dataframe. However, these comparison operators will not work as expected on string values like the ones you have in your time column. Instead of using these operators, you can use the str.slice() method to extract the hour portion of the time strings and then use the comparison operators on those numeric values to specify your time range. Here is an example of how you could do this: # First, extract the hour portion of the time strings df['hour'] = df['time'].str.slice(0, 2) # Next, create a boolean mask using the comparison operators on the 'hour' column time_period = (df['hour'] >= '01') & (df['hour'] <= '05') # Finally, use this boolean mask to create your time period dataframe time_period_df = df.loc[time_period] This should give you a dataframe that includes only the rows with time values between and including 1:00:00 and 5:00:00. Note that this solution assumes that the time strings in your time column are in the format 'HH:MM:SS'. If the time strings are in a different format, you will need to adjust the str.slice() call accordingly.

Q: What's the point of conforming to an empty protocol in Swift I'm just working on a codebase where the most classes conform to an empty protocol. Is there any point of doing so? Actually conforming that protocol does nothing. Edit as reaction to @vacawama's helpful comment : the protocol is only used once import Foundation protocol myUrlRequestConfig {} extension myUrlRequest: myUrlRequestConfig { public static func configGetAppConfig() -> URLRequest { let request = .... return request } } A: An empty protocol can be useful if you want to create an easy way to add static functions or variables to several different classes. Of course, this only makes sense if the static functionality is the same for all classes conforming to the protocol. Here is an example: I have a protocol sizeable. Every class that conforms to Sizeable is extended with the static variable stride and size. protocol Sizeable { } extension Sizeable { static var size: Int { return MemoryLayout<Self>.size } static var stride: Int { return MemoryLayout<Self>.stride } } class Foo: Sizeable {} class Baa: Sizeable {} Foo.size Baa.size A: Our app has three perfectly legitimate uses for an empty protocol: The protocol has an extension with method definitions. The implementation in the extension is automatically injected into any type that adopts the protocol. The protocol has other protocols that adopt it. This allows multiple protocols to be unified under a single head. The protocol marks the adopter as wanting some other type to behave in a certain way. Code can always is whether an object is ThisEmptyProtocol and if it is, can behave differently than if it isn't.

Q: How to write a cobol code to read master file and retrieve pm-h-apl field, How to write a cobol code to read master file and retrieve pm-h-apl field, IF this apl indicator field will be spaces move 'N' to pm-h-apl field How to write a cobol code to read master file and retrieve pm-h-apl field, IF this apl indicator field will be spaces move 'N' to pm-h-apl field. A: You can use the READ statement to read from the master file and the MOVE statement to move values to the pm-h-apl field. The following code demonstrates how this can be done: MOVE SPACES TO pm-h-apl READ master-file AT END MOVE 'N' TO pm-h-apl NOT AT END IF pm-h-apl = SPACES MOVE 'N' TO pm-h-apl END-READ Here, we first initialize the pm-h-apl field with spaces using the MOVE statement. Then, we use the READ statement to read from the master file. If the end of the file is reached (indicated by the AT END clause), we move 'N' to the pm-h-apl field. If the end of the file is not reached (indicated by the NOT AT END clause), we check if the pm-h-apl field is equal to spaces, and if it is, we move 'N' to the pm-h-apl field. The END-READ statement marks the end of the READ block.

Turned out the autofill in my browser was filling it in the field for site 'localhost'. Confirmed after running the code in Firefox where I have no autofill setup.

Q: How can I fix dark textures? - Godot 3.5.1 Mono So, I'm making a game in Godot 3.5.1 Mono and I'm using a Texture in a 3D space (Spatial) while I'm using it as a Control Element and it is showing up as dark in the editor and in-game. Here is what it looks like in the Editor, 3D space (Spatial), and the GUI (Control) Here is the window of the scene and the import settings I want a normal texture like this - not dark A: Have two copies of the Texture. You probably can make it look correct in 2D by changing "HDR mode" to "Force RGBE" when the compress mode is "Video RAM". However fixing the 2D look might ruin the 3D look (this appears to be related to whether or not the png was saved with multiplied alpha - I don't know for sure, and I don't mean the import setting - so your mileage may vary). If you cannot find import settings that works for both 2D and 3D, I suggest to have two copies of the image file, one for 2D and one for 3D. So they can both have correct import settings for the context in which they are used. In fact, I would default to that in the future.

I also tried to do it with lists, but with that too it takes too much time. def pyramid_blocks(n, m, h): return sum((n+i)*(m+i) for i in range(h)) def pyramid_blocks(n, m, h): r=[] t=[] mlp=[] for i in range(h): r.append(n+i) t.append(m+i) for i, j in zip(r,t): mlp.append(i*j) return sum(mlp)

Q: Moving CALayer's mask on scroll in a Scrollview I am experimenting with iOS SDK and I have the following UIView structure: UIView UIImageView - only a background image UIImageView (with a CALayer mask) UIScrollView Label Very simple structure, UIScrollView is transparent layer and second UIImageView has a mask on it. What I am trying to do is that CALayer mask would move its position according to position of the Content in the scroll view. If user scrolls, mask's position should be updated. I already solved this problem by using UIScrollView's delegate: - (void)scrollViewDidScroll:(UIScrollView *)scrollView { CGPoint contentOffset = scrollView.contentOffset; contentOffset.y = -contentOffset.y; self.overlayImageView.viewlayer.mask.position = contentOffset; } Mask is created in viewDidLoad and does not change during view controller's lifecycle. The problem is that the mask position updating is too slow. That way it looks the mask is following the scroll view's content, not scrolling with it. The scrollViewDidScroll delegate method is called correctly. For you to better understand the problem, I am attaching a video I made in iOS simulator. http://www.youtube.com/watch?v=w3xRl3LTngY So the question is: Is there a way to make mask updating faster or this is the limit of iOS? A: CALayer are implicit animated for some properties like position try to disable them: - (void)scrollViewDidScroll:(UIScrollView *)scrollView { [CATransaction begin]; [CATransaction setValue:(id)kCFBooleanTrue forKey:kCATransactionDisableActions]; CGPoint contentOffset = scrollView.contentOffset; contentOffset.y = -contentOffset.y; self.overlayImageView.viewlayer.mask.position = contentOffset; [CATransaction commit]; } A: For me solution was as following: func scrollViewDidScroll(_ scrollView: UIScrollView) { CATransaction.begin() CATransaction.setDisableActions(true) layerGradient?.frame = scrollView.safeAreaLayoutGuide.layoutFrame CATransaction.commit() }

Q: Filtering on multiple fields in an Elasticsearch ObjectField() I am having trouble figuring out the filtering syntax for ObjectFields() in django-elasticsearch-dsl. In particular, when I try to filter on multiple subfields of the same ObjectField(), I'm getting incorrect results. For example, consider the following document class ItemDocument(Document): product = fields.ObjectField(properties={ 'id': fields.IntegerField(), 'name': fields.TextField(), 'description': fields.TextField() }) details = fields.ObjectField(properties={ 'category_id': fields.IntegerField(), 'id': fields.IntegerField(), 'value': fields.FloatField() }) description = fields.TextField() I want to find an Item with a detail object that has both category_id == 3 and value < 1.5, so I created the following query x = ItemDocument.search().filter(Q("match",details__category_id=3) & Q("range",details__value={'lt':1.5})).execute() Unfortunately, this returns all items which have a detail object with category_id==3 and a separate detail object with value < 1.5 e.g. { "product": ... "details": [ { "category_id": 3, "id": 7, "value": 20.0 }, { "category_id": 4, "id": 7, "value": 1.0 }, ... ] } instead of my desired result of all items that have a detail object with both category_id==3 AND value < 1.5 e.g. { "product": ... "details": [ { "category_id": 3, "id": 7, "value": 1.0 }, ... ] } How do I properly format this query using django-elasticsearch-dsl? A: You can use the nested query in Elasticsearch to filter on multiple subfields of the same ObjectField. Here is an example of how you can do this in django-elasticsearch-dsl: x = ItemDocument.search().query( "nested", path="details", query=Q("match", details__category_id=3) & Q("range", details__value={'lt':1.5}) ).execute() The nested query allows you to filter on multiple subfields of the details object, and only return documents that have a detail object with both category_id==3 and value < 1.5. You can also use the inner_hits option with the nested query to get the details of the matching detail objects: x = ItemDocument.search().query( "nested", path="details", query=Q("match", details__category_id=3) & Q("range", details__value={'lt':1.5}), inner_hits={} ).execute() This will add a nested field to each search result, which contains the details of the matching detail objects. You can access this field in your code like this: results = x.to_dict() for result in results['hits']['hits']: nested_results = result['inner_hits']['details']['hits']['hits'] # do something with nested_results

Q: does @Transactional annotation merge new transaction into exisiting transaction i am having a simple controller /hello which internally calls Repository layer for a transaction using the default propagation level i.e Propagation.REQUIRED. @Controller public void hello(data) -> doTransaction(data) @Repository @Transactional public void doTransaction(data){ jdbcTemplateInsertA(data); Thread.sleep(15*1000); jdbcTemplateUpdateB(data); } as per online docs REQUIRED is the default propagation. Spring checks if there is an active transaction, and if nothing exists, it creates a new one. Otherwise, the business logic appends to the currently active transaction: now let's say i hit the API 2 times, with data1 and then data2, before request 1 was finished API was hit 2nd time. would there be only a single transaction or two separate independent transactions? Also, i want to know is using @Transactional with jdbcTemplate valid? i am having doubt on how jdbcTemplate internally gets the same connection object that was used by @Transactional annotation considering pool size >=2. UPDATE: You will have a transaction per thread. -> any docs/resources where i can find this? For 2nd part, let me rephrase my question. Let's say using hikari pool with size as 5 as per my understanding @Transactional would pick some connection from pool, let's say it picked up connectionId1554 now, when i call jdbc.execute(), how spring ensure that it uses connectionId1554 and not any other available connection from the pool A: You will have a transaction per thread. If you have two requests, then you will have two threads (from your web container, like Tomcat), and therefore you'll have two separate transactions. Based on the code and (lack of) configuration it is hard to tell how you setup your JdbcTemplate. Most likely the connection used by the JdbcTemplate comes from a database connection pool. If you've configured two connections then you can only use two connections and the usage of those connections will block other requests to the database if they are in use. Now, that being said, database connection pools are generally programmed to be super smart and one database connection can be used between multiple database requests/transactions depending on configuration settings. A: let's say i hit the API 2 times, with data1 and then data2, before request 1 was finished API was hit 2nd time. would there be only a single transaction or two separate independent transactions? Each incoming request to your api will result in an independent transaction being started. If you think this through this makes sense: if you have 2 users each making a request at the same time, you would want each of their requests to be handled independently, it would be odd if both of their requests joined and were handled as a single transaction. i want to know is using @Transactional with jdbcTemplate valid? i am having doubt on how jdbcTemplate internally gets the same connection object that was used by @Transactional annotation This depends on how you have configured a Datasource and a connection pool. Are you running this on an appserver like Webpshere, Weblogic or WildFly? They provide Datasource connection pooling integrated with a TransactionManager too.

Q: Use trained ML to classify new dataset I have save my ML model that have been train. ML that I chose is SVM and I'm using pickle to save it. How can I use this model to classify new dataset which in csv file that have no sentiment label in it? I'm using Jupyter Notebook to do this project A: It would be useful to know what library (sklearn, pytorch, tensorflow, etc.) you used to train the model, but for this example I'm going to assume you used the pickle library to pickle and the sklearn library to train the model. At some point you used something like pickle.dump(model, open(filename, 'wb')) to save your model. You can also use pickle to load the model through pickle.load(open(filename, 'rb')) and then call the model through model.predict(new_X) where new_X represents the dataframe you want to make the predictions on.

Q: How can i call a different functions seperately using a single button I have to create a calculator but i have to use separate functions for add , subtract , division and multiply there should be an equal to (=) button which upon clicking should display the result operators should be selected using the dropdown box <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>calculator</title> </head> <body> <h1 align="center">calculator</h1> <script type="text/javascript"> function add() { var a=parseInt(document.getElementById("firstnumber").value); var b=parseInt(document.getElementById("secondnumber").value); var c=a+b document.getElementById("answer").innerHTML=c; } function sub() { var a=parseInt(document.getElementById("firstnumber").value); var b=parseInt(document.getElementById("secondnumber").value); var c=a-b; document.getElementById("answer").innerHTML=c; } function mul() { var a=parseInt(document.getElementById("firstnumber").value); var b=parseInt(document.getElementById("secondnumber").value); var c=a*b; document.getElementById("answer").innerHTML=c; } function div() { var a=parseInt(document.getElementById("firstnumber").value); var b=parseInt(document.getElementById("secondnumber").value); var c=a/b; document.getElementById("answer").innerHTML=c; } </script> <p>First Number: <input id="firstnumber"></p> <p>Second Number: <input id="secondnumber"></p> <select id="operators"> <option value="add" onclick="add()">+</option> <option value="sub" onclick="sub()">-</option> <option value="mul" onclick="mul()">*</option> <option value="div" onclick="div()">/</option> </select> <button onclick="add.call(this);sub.call(this);mul.call(this);div.call(this);">=</button> <p id="answer"></p> </body> </html> A: i think thats what you were looking for. make sure to read what i wrote under the code index.html: <!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1" /> <title>calculator</title> </head> <body> <h1 align="center">calculator</h1> <p>First Number: <input id="firstnumber" /></p> <p>Second Number: <input id="secondnumber" /></p> <select id="operators"> <option value="add">+</option> <option value="sub">-</option> <option value="mul">*</option> <option value="div">/</option> </select> <button id="calcBtn">=</button> <p id="answer"></p> <script src="script.js"></script> </body> </html> script.js: document.getElementById("calcBtn").addEventListener("click", () => { let operator = document.getElementById("operators").value; let a = parseInt(document.getElementById("firstnumber").value); let b = parseInt(document.getElementById("secondnumber").value); switch (operator) { case "add": add(); break; case "sub": sub(); break; case "mul": mul(); break; case "div": div(); break; default: break; } function add() { let c = a + b; document.getElementById("answer").innerHTML = c; } function sub() { let c = a - b; document.getElementById("answer").innerHTML = c; } function mul() { let c = a * b; document.getElementById("answer").innerHTML = c; } function div() { let c = a / b; document.getElementById("answer").innerHTML = c; } }); dont use onclick, give element an id and then add event listenner to it works the same but addeventlistenner is better you can replace .addEventListener("click", () => { with .addEventListener("click", function() { its up to you always place your script tag directly above the body tag use script src instead of script > code, it makes the html more clean use let instead of var switch case its like if, but in situations like that better, because its easier to write what to do depending on the value usage: switch(variable){ case "variable value": code break; } i think thats all A: To call multiple functions using a single button, you can use a JavaScript function that calls the other functions in the desired order. Here is an example of how you can do that: <!-- HTML code for the calculator --> <p>First Number: <input id="firstnumber"></p> <p>Second Number: <input id="secondnumber"></p> <select id="operators"> <option value="add">+</option> <option value="sub">-</option> <option value="mul">*</option> <option value="div">/</option> </select> <button onclick="computeResult()">=</button> <p id="answer"></p> <!-- JavaScript code for the calculator --> <script> function computeResult() { // Get the selected operator var operator = document.getElementById("operators").value; // Call the appropriate function based on the selected operator if (operator === "add") { add(); } else if (operator === "sub") { sub(); } else if (operator === "mul") { mul(); } else if (operator === "div") { div(); } } function add() { var a = parseInt(document.getElementById("firstnumber").value); var b = parseInt(document.getElementById("secondnumber").value); var c = a + b; document.getElementById("answer").innerHTML = c; } function sub() { var a = parseInt(document.getElementById("firstnumber").value); var b = parseInt(document.getElementById("secondnumber").value); var c = a - b; document.getElementById("answer").innerHTML = c; } function mul() { var a = parseInt(document.getElementById("firstnumber").value); var b = parseInt(document.getElementById("secondnumber").value); var c = a * b; document.getElementById("answer").innerHTML = c; } function div() { var a = parseInt(document.getElementById("firstnumber").value); var b = parseInt(document.getElementById("secondnumber").value); var c = a / b; document.getElementById("answer").innerHTML = c; } </script> In this example, the computeResult() function is called when the = button is clicked. It gets the selected operator from the dropdown box, and then calls the appropriate function (add(), sub(), mul(), or div()) based on the selected operator.

Q: Unity: Use Inherited properties component or Inspector Injected components I'm new to Unity but have development experience. I'd like to know whether I should be using the inherited properties in my MonoBehaviour scripts, or if I should be injecting everything from the inspector instead. I'm following a tutorial that has suggested writing some code like this: public class BirdScript : MonoBehaviour { public Rigidbody2D myRigidbody; So that the Inspector can inject the component's Rigidbody2D into it: When playing with the code, I noticed that MonoBehaviour extends Component and I can do this.rigidbody2D instead. I got told off by Intellisense for this, but it suggested instead using: GetComponent<Rigidbody2D>(). Using this, instead of my code reading: void Update() { myRigidbody.velocity = Vector2.up * 10; } I can write: void Update() { GetComponent<Rigidbody2D>().velocity = Vector2.up * 10; } But which is better? I'm thinking GetComponent<Rigidbody2D>() because it makes sure that I'm directly referencing the current rigid body that my script is attached to, instead of requiring me to apply things in the Inspector, but maybe this is too inflexible for Unity? In general, the style seems more lenient towards making things public instead of private for the sake of the Inspector. Any advice on some best practices I can use to make these kinds of decisions? A: Assigning a reference through the inspector or referencing an attached component using GetComponent<T> are both valid options. Although I would generally avoid calling GetComponent<Rigidbody2D>() in the Update() function since it's expensive, and instead cache the reference in Start(). The Start method is called after all initialization methods have been completed, so it is safe to use GetComponent in this method to access fully initialized components. private Rigidbody _rigidbody; private void Start() { _rigidbody = GetComponent<Rigidbody2D>(); } Referencing Components One potential downside of referencing components through drag-and-drop in the Unity Inspector is that managing your project's dependencies can be challenging. This is because drag-and-drop references can create implicit dependencies that are not immediately obvious from looking at the code. This can make it difficult to understand how different parts of your project are interconnected and can make it harder to refactor or modify your code in the future. As such, .GetComponent provides an alternative in-code solution. GameObject.GetComponent One potential downside of using GetComponent to create component references in Unity is that it can make your code more difficult to read and understand because GetComponent calls could be spread throughout your code. In contrast, drag-and-drop references in the Unity Inspector can be easily seen and understood by looking at the inspector window for a particular game object. Another potential downside of using GetComponent is that it can make your code more fragile. This is because GetComponent calls rely on the components attached to the game object at runtime and will throw an error if the required component is not present. However, this could be alleviated using the RequireComponent attribute, making said components dependent. In contrast, drag-and-drop references in the Unity Inspector are checked at edit time and will only allow you to reference components attached to the game object. This can help to prevent runtime errors in your code. Overall, whether to use GetComponent or drag-and-drop references in the Unity Inspector will depend on your personal preferences and the specific needs of your project. Both approaches have advantages and disadvantages, and the best approach for your project depends on the specific circumstances.

For example, you can replace the line x2(1,i)=x1 with the following: x2 = cat(2, x2, x1) This will add the new value to the end of the existing matrix, without overwriting the existing values. Alternatively, you can pre-allocate the matrix with the desired number of columns, using the zeros function. For example, you can replace the line x2 = 0 with the following: x2 = zeros(1, n) This will create a matrix with one row and n columns, all filled with zeros. Then, when you add new values to the matrix, they will be added to the next empty column, without overwriting any existing values. You can also use the size function to dynamically determine the size of the matrix, and add new values to the next empty column. For example, you can replace the line x2(1,i)=x1 with the following: [numRows, numCols] = size(x2) x2(1, numCols+1) = x1 This will determine the number of columns in the existing matrix, and add the new value to the next empty column. Note that you will need to initialize the matrix with at least one column, for example using x2 = 0.

Q: How can I copy a file on Unix using C? I'm looking for the Unix equivalent of Win32's CopyFile, I don't want to reinvent the wheel by writing my own version. A: There is no need to either call non-portable APIs like sendfile, or shell out to external utilities. The same method that worked back in the 70s still works now: #include <fcntl.h> #include <unistd.h> #include <errno.h> int cp(const char *to, const char *from) { int fd_to, fd_from; char buf[4096]; ssize_t nread; int saved_errno; fd_from = open(from, O_RDONLY); if (fd_from < 0) return -1; fd_to = open(to, O_WRONLY | O_CREAT | O_EXCL, 0666); if (fd_to < 0) goto out_error; while (nread = read(fd_from, buf, sizeof buf), nread > 0) { char *out_ptr = buf; ssize_t nwritten; do { nwritten = write(fd_to, out_ptr, nread); if (nwritten >= 0) { nread -= nwritten; out_ptr += nwritten; } else if (errno != EINTR) { goto out_error; } } while (nread > 0); } if (nread == 0) { if (close(fd_to) < 0) { fd_to = -1; goto out_error; } close(fd_from); /* Success! */ return 0; } out_error: saved_errno = errno; close(fd_from); if (fd_to >= 0) close(fd_to); errno = saved_errno; return -1; } A: There is no baked-in equivalent CopyFile function in the APIs. But sendfile can be used to copy a file in kernel mode which is a faster and better solution (for numerous reasons) than opening a file, looping over it to read into a buffer, and writing the output to another file. Update: As of Linux kernel version 2.6.33, the limitation requiring the output of sendfile to be a socket was lifted and the original code would work on both Linux and — however, as of OS X 10.9 Mavericks, sendfile on OS X now requires the output to be a socket and the code won't work! The following code snippet should work on the most OS X (as of 10.5), (Free)BSD, and Linux (as of 2.6.33). The implementation is "zero-copy" for all platforms, meaning all of it is done in kernelspace and there is no copying of buffers or data in and out of userspace. Pretty much the best performance you can get. #include <fcntl.h> #include <unistd.h> #if defined(__APPLE__) || defined(__FreeBSD__) #include <copyfile.h> #else #include <sys/sendfile.h> #endif int OSCopyFile(const char* source, const char* destination) { int input, output; if ((input = open(source, O_RDONLY)) == -1) { return -1; } if ((output = creat(destination, 0660)) == -1) { close(input); return -1; } //Here we use kernel-space copying for performance reasons #if defined(__APPLE__) || defined(__FreeBSD__) //fcopyfile works on FreeBSD and OS X 10.5+ int result = fcopyfile(input, output, 0, COPYFILE_ALL); #else //sendfile will work with non-socket output (i.e. regular file) on Linux 2.6.33+ off_t bytesCopied = 0; struct stat fileinfo = {0}; fstat(input, &fileinfo); int result = sendfile(output, input, &bytesCopied, fileinfo.st_size); #endif close(input); close(output); return result; } EDIT: Replaced the opening of the destination with the call to creat() as we want the flag O_TRUNC to be specified. See comment below. A: It's straight forward to use fork/execl to run cp to do the work for you. This has advantages over system in that it is not prone to a Bobby Tables attack and you don't need to sanitize the arguments to the same degree. Further, since system() requires you to cobble together the command argument, you are not likely to have a buffer overflow issue due to sloppy sprintf() checking. The advantage to calling cp directly instead of writing it is not having to worry about elements of the target path existing in the destination. Doing that in roll-you-own code is error-prone and tedious. I wrote this example in ANSI C and only stubbed out the barest error handling, other than that it's straight forward code. void copy(char *source, char *dest) { int childExitStatus; pid_t pid; int status; if (!source || !dest) { /* handle as you wish */ } pid = fork(); if (pid == 0) { /* child */ execl("/bin/cp", "/bin/cp", source, dest, (char *)0); } else if (pid < 0) { /* error - couldn't start process - you decide how to handle */ } else { /* parent - wait for child - this has all error handling, you * could just call wait() as long as you are only expecting to * have one child process at a time. */ pid_t ws = waitpid( pid, &childExitStatus, WNOHANG); if (ws == -1) { /* error - handle as you wish */ } if( WIFEXITED(childExitStatus)) /* exit code in childExitStatus */ { status = WEXITSTATUS(childExitStatus); /* zero is normal exit */ /* handle non-zero as you wish */ } else if (WIFSIGNALED(childExitStatus)) /* killed */ { } else if (WIFSTOPPED(childExitStatus)) /* stopped */ { } } } A: Another variant of the copy function using normal POSIX calls and without any loop. Code inspired from the buffer copy variant of the answer of caf. Warning: Using mmap can easily fail on 32 bit systems, on 64 bit system the danger is less likely. #include <fcntl.h> #include <unistd.h> #include <errno.h> #include <sys/mman.h> int cp(const char *to, const char *from) { int fd_from = open(from, O_RDONLY); if(fd_from < 0) return -1; struct stat Stat; if(fstat(fd_from, &Stat)<0) goto out_error; void *mem = mmap(NULL, Stat.st_size, PROT_READ, MAP_SHARED, fd_from, 0); if(mem == MAP_FAILED) goto out_error; int fd_to = creat(to, 0666); if(fd_to < 0) goto out_error; ssize_t nwritten = write(fd_to, mem, Stat.st_size); if(nwritten < Stat.st_size) goto out_error; if(close(fd_to) < 0) { fd_to = -1; goto out_error; } close(fd_from); /* Success! */ return 0; } out_error:; int saved_errno = errno; close(fd_from); if(fd_to >= 0) close(fd_to); errno = saved_errno; return -1; } EDIT: Corrected the file creation bug. See comment in http://stackoverflow.com/questions/2180079/how-can-i-copy-a-file-on-unix-using-c/2180157#2180157 answer. A: There is a way to do this, without resorting to the system call, you need to incorporate a wrapper something like this: #include <sys/sendfile.h> #include <fcntl.h> #include <unistd.h> /* ** http://www.unixguide.net/unix/programming/2.5.shtml ** About locking mechanism... */ int copy_file(const char *source, const char *dest){ int fdSource = open(source, O_RDWR); /* Caf's comment about race condition... */ if (fdSource > 0){ if (lockf(fdSource, F_LOCK, 0) == -1) return 0; /* FAILURE */ }else return 0; /* FAILURE */ /* Now the fdSource is locked */ int fdDest = open(dest, O_CREAT); off_t lCount; struct stat sourceStat; if (fdSource > 0 && fdDest > 0){ if (!stat(source, &sourceStat)){ int len = sendfile(fdDest, fdSource, &lCount, sourceStat.st_size); if (len > 0 && len == sourceStat.st_size){ close(fdDest); close(fdSource); /* Sanity Check for Lock, if this is locked -1 is returned! */ if (lockf(fdSource, F_TEST, 0) == 0){ if (lockf(fdSource, F_ULOCK, 0) == -1){ /* WHOOPS! WTF! FAILURE TO UNLOCK! */ }else{ return 1; /* Success */ } }else{ /* WHOOPS! WTF! TEST LOCK IS -1 WTF! */ return 0; /* FAILURE */ } } } } return 0; /* Failure */ } The above sample (error checking is omitted!) employs open, close and sendfile. Edit: As caf has pointed out a race condition can occur between the open and stat so I thought I'd make this a bit more robust...Keep in mind that the locking mechanism varies from platform to platform...under Linux, this locking mechanism with lockf would suffice. If you want to make this portable, use the #ifdef macros to distinguish between different platforms/compilers...Thanks caf for spotting this...There is a link to a site that yielded "universal locking routines" here. A: Copying files byte-by-byte does work, but is slow and wasteful on modern UNIXes. Modern UNIXes have “copy-on-write” support built-in to the filesystem: a system call makes a new directory entry pointing at the existing bytes on disk, and no file content bytes on disk are touched until one of the copies is modified, at which point only the changed blocks are written to disk. This allows near-instant file copies that use no additional file blocks, regardless of file size. For example, here are some details about how this works in xfs. On linux, use the FICLONE ioctl as coreutils cp now does by default. #ifdef FICLONE return ioctl (dest_fd, FICLONE, src_fd); #else errno = ENOTSUP; return -1; #endif On macOS, use clonefile(2) for instant copies on APFS volumes. This is what Apple’s cp -c uses. The docs are not completely clear but it is likely that copyfile(3) with COPYFILE_CLONE also uses this. Leave a comment if you’d like me to test that. In case these copy-on-write operations are not supported—whether the OS is too old, the underlying file system does not support it, or because you are copying files between different filesystems—you do need to fall back to trying sendfile, or as a last resort, copying byte-by-byte. But to save everyone a lot of time and disk space, please give FICLONE and clonefile(2) a try first. A: I see nobody mentioned yet copy_file_range, supported at least on Linux and FreeBSD. The advantage of this one is that it explicitly documents ability of making use of CoW techniques like reflinks. Quoting: copy_file_range() gives filesystems an opportunity to implement "copy acceleration" techniques, such as the use of reflinks (i.e., two or more inodes that share pointers to the same copy-on-write disk blocks) or server-side-copy (in the case of NFS). FWIW, I am not sure if older sendfile is able to do that. The few mentions I found claim that it doesn't. In that sense, copy_file_range is superior to sendfile. Below is an example of using the call (which is copied verbatim from the manual). I also checked that after using this code to copy a bash binary within BTRFS filesystem, the copy is reflinked to the original (I did that by calling duperemove on the files, and seeing Skipping - extents are already deduped. messages). #define _GNU_SOURCE #include <fcntl.h> #include <stdio.h> #include <stdlib.h> #include <sys/stat.h> #include <unistd.h> int main(int argc, char **argv) { int fd_in, fd_out; struct stat stat; off64_t len, ret; if (argc != 3) { fprintf(stderr, "Usage: %s <source> <destination>\n", argv[0]); exit(EXIT_FAILURE); } fd_in = open(argv[1], O_RDONLY); if (fd_in == -1) { perror("open (argv[1])"); exit(EXIT_FAILURE); } if (fstat(fd_in, &stat) == -1) { perror("fstat"); exit(EXIT_FAILURE); } len = stat.st_size; fd_out = open(argv[2], O_CREAT | O_WRONLY | O_TRUNC, 0644); if (fd_out == -1) { perror("open (argv[2])"); exit(EXIT_FAILURE); } do { ret = copy_file_range(fd_in, NULL, fd_out, NULL, len, 0); if (ret == -1) { perror("copy_file_range"); exit(EXIT_FAILURE); } len -= ret; } while (len > 0 && ret > 0); close(fd_in); close(fd_out); exit(EXIT_SUCCESS); } A: One option is that you could use system() to execute cp. This just re-uses the cp(1) command to do the work. If you only need to make another link to the file, this can be done with link() or symlink(). A: #include <unistd.h> #include <string.h> #include <errno.h> #include <fcntl.h> #include <sys/types.h> #include <sys/stat.h> #include <stdio.h> #define print_err(format, args...) printf("[%s:%d][error]" format "\n", __func__, __LINE__, ##args) #define DATA_BUF_SIZE (64 * 1024) //limit to read maximum 64 KB data per time int32_t get_file_size(const char *fname){ struct stat sbuf; if (NULL == fname || strlen(fname) < 1){ return 0; } if (stat(fname, &sbuf) < 0){ print_err("%s, %s", fname, strerror(errno)); return 0; } return sbuf.st_size; /* off_t shall be signed interge types, used for file size */ } bool copyFile(CHAR *pszPathIn, CHAR *pszPathOut) { INT32 fdIn, fdOut; UINT32 ulFileSize_in = 0; UINT32 ulFileSize_out = 0; CHAR *szDataBuf; if (!pszPathIn || !pszPathOut) { print_err(" Invalid param!"); return false; } if ((1 > strlen(pszPathIn)) || (1 > strlen(pszPathOut))) { print_err(" Invalid param!"); return false; } if (0 != access(pszPathIn, F_OK)) { print_err(" %s, %s!", pszPathIn, strerror(errno)); return false; } if (0 > (fdIn = open(pszPathIn, O_RDONLY))) { print_err("open(%s, ) failed, %s", pszPathIn, strerror(errno)); return false; } if (0 > (fdOut = open(pszPathOut, O_CREAT | O_WRONLY | O_TRUNC, 0777))) { print_err("open(%s, ) failed, %s", pszPathOut, strerror(errno)); close(fdIn); return false; } szDataBuf = malloc(DATA_BUF_SIZE); if (NULL == szDataBuf) { print_err("malloc() failed!"); return false; } while (1) { INT32 slSizeRead = read(fdIn, szDataBuf, sizeof(szDataBuf)); INT32 slSizeWrite; if (slSizeRead <= 0) { break; } slSizeWrite = write(fdOut, szDataBuf, slSizeRead); if (slSizeWrite < 0) { print_err("write(, , slSizeRead) failed, %s", slSizeRead, strerror(errno)); break; } if (slSizeWrite != slSizeRead) /* verify wheter write all byte data successfully */ { print_err(" write(, , %d) failed!", slSizeRead); break; } } close(fdIn); fsync(fdOut); /* causes all modified data and attributes to be moved to a permanent storage device */ close(fdOut); ulFileSize_in = get_file_size(pszPathIn); ulFileSize_out = get_file_size(pszPathOut); if (ulFileSize_in == ulFileSize_out) /* verify again wheter write all byte data successfully */ { free(szDataBuf); return true; } free(szDataBuf); return false; } A: sprintf( cmd, "/bin/cp -p \'%s\' \'%s\'", old, new); system( cmd); Add some error checks... Otherwise, open both and loop on read/write, but probably not what you want. ... UPDATE to address valid security concerns: Rather than using "system()", do a fork/wait, and call execv() or execl() in the child. execl( "/bin/cp", "-p", old, new); A: Very simple : #define BUF_SIZE 65536 int cp(const char *from, const char*to){ FILE *src, *dst; size_t in, out; char *buf = (char*) malloc(BUF_SIZE* sizeof(char)); src = fopen(from, "rb"); if (NULL == src) exit(2); dst = fopen(to, "wb"); if (dst < 0) exit(3); while (1) { in = fread(buf, sizeof(char), BUF_SIZE, src); if (0 == in) break; out = fwrite(buf, sizeof(char), in, dst); if (0 == out) break; } fclose(src); fclose(dst); } Works on windows and linux. A: Good question. Related to another good question: In C on linux how would you implement cp There are two approaches to the "simplest" implementation of cp. One approach uses a file copying system call function of some kind - the closest thing we get to a C function version of the Unix cp command. The other approach uses a buffer and read/write system call functions, either directly, or using a FILE wrapper. It's likely the file copying system calls that take place solely in kernel-owned memory are faster than the system calls that take place in both kernel- and user-owned memory, especially in a network filesystem setting (copying between machines). But that would require testing (e.g. with Unix command time) and will be dependent on the hardware where the code is compiled and executed. It's also likely that someone with an OS that doesn't have the standard Unix library will want to use your code. Then you'd want to use the buffer read/write version, since it only depends on <stdlib.h> and <stdio.h> (and friends) <unistd.h> Here's an example that uses function copy_file_range from the unix standard library <unistd.h>, to copy a source file to a (possible non-existent) destination file. The copy takes place in kernel space. /* copy.c * * Defines function copy: * * Copy source file to destination file on the same filesystem (possibly NFS). * If the destination file does not exist, it is created. If the destination * file does exist, the old data is truncated to zero and replaced by the * source data. The copy takes place in the kernel space. * * Compile with: * * gcc copy.c -o copy -Wall -g */ #define _GNU_SOURCE #include <fcntl.h> #include <stdio.h> #include <stdlib.h> #include <sys/stat.h> #include <sys/syscall.h> #include <unistd.h> /* On versions of glibc < 2.27, need to use syscall. * * To determine glibc version used by gcc, compute an integer representing the * version. The strides are chosen to allow enough space for two-digit * minor version and patch level. * */ #define GCC_VERSION (__GNUC__*10000 + __GNUC_MINOR__*100 + __gnuc_patchlevel__) #if GCC_VERSION < 22700 static loff_t copy_file_range(int in, loff_t* off_in, int out, loff_t* off_out, size_t s, unsigned int flags) { return syscall(__NR_copy_file_range, in, off_in, out, off_out, s, flags); } #endif /* The copy function. */ int copy(const char* src, const char* dst){ int in, out; struct stat stat; loff_t s, n; if(0>(in = open(src, O_RDONLY))){ perror("open(src, ...)"); exit(EXIT_FAILURE); } if(fstat(in, &stat)){ perror("fstat(in, ...)"); exit(EXIT_FAILURE); } s = stat.st_size; if(0>(out = open(dst, O_CREAT|O_WRONLY|O_TRUNC, 0644))){ perror("open(dst, ...)"); exit(EXIT_FAILURE); } do{ if(1>(n = copy_file_range(in, NULL, out, NULL, s, 0))){ perror("copy_file_range(...)"); exit(EXIT_FAILURE); } s-=n; }while(0<s && 0<n); close(in); close(out); return EXIT_SUCCESS; } /* Test it out. * * BASH: * * gcc copy.c -o copy -Wall -g * echo 'Hello, world!' > src.txt * ./copy src.txt dst.txt * [ -z "$(diff src.txt dst.txt)" ] * */ int main(int argc, char* argv[argc]){ if(argc!=3){ printf("Usage: %s <SOURCE> <DESTINATION>", argv[0]); exit(EXIT_FAILURE); } copy(argv[1], argv[2]); return EXIT_SUCCESS; } It's based on the example in my Ubuntu 20.x Linux distribution's man page for copy_file_range. Check your man pages for it with: > man copy_file_range Then hit j or Enter until you get to the example section. Or search by typing /example. <stdio.h>/<stdlib.h> only Here's an example that only uses stdlib/stdio. The downside is it uses an intermediate buffer in user-space. /* copy.c * * Compile with: * * gcc copy.c -o copy -Wall -g * * Defines function copy: * * Copy a source file to a destination file. If the destination file already * exists, this clobbers it. If the destination file does not exist, it is * created. * * Uses a buffer in user-space, so may not perform as well as * copy_file_range, which copies in kernel-space. * */ #include <stdlib.h> #include <stdio.h> #define BUF_SIZE 65536 //2^16 int copy(const char* in_path, const char* out_path){ size_t n; FILE* in=NULL, * out=NULL; char* buf = calloc(BUF_SIZE, 1); if((in = fopen(in_path, "rb")) && (out = fopen(out_path, "wb"))) while((n = fread(buf, 1, BUF_SIZE, in)) && fwrite(buf, 1, n, out)); free(buf); if(in) fclose(in); if(out) fclose(out); return EXIT_SUCCESS; } /* Test it out. * * BASH: * * gcc copy.c -o copy -Wall -g * echo 'Hello, world!' > src.txt * ./copy src.txt dst.txt * [ -z "$(diff src.txt dst.txt)" ] * */ int main(int argc, char* argv[argc]){ if(argc!=3){ printf("Usage: %s <SOURCE> <DESTINATION>\n", argv[0]); exit(EXIT_FAILURE); } return copy(argv[1], argv[2]); } A: Simple question: What should happen when the source and destination files are the same, with such a self-written C copy-file function? Naturally, I would except an error like with the cp command: $ cp xx.txt xx.txt cp: 'xx.txt' and 'xx.txt' are the same file Quite simple to test the file names (assuming SBCS or UTF-8): const char * src; const char * dst; ... if (src == dst || strcmp(src, dst) == 0) return -1; But the devil is in the details: What if one of the file names is a symbolic link that points to the file containing the data? I started looking at corutils cp.c/copy.c sources => check same_file_ok() ... Seb

A: It looks like the error is occurring in the sendEmail function. It seems that you're not returning anything from this function, which means that it will always return null. This is causing the $sentstatus variable to be null and thus the if($sentstatus==true) block is never executed. To fix this, you can simply add a return $result statement at the end of the sendEmail function. This will return the result of the $this->email->send() call and allow you to properly check if the email was sent successfully or not (and see the error message if not). Here is how the updated sendEmail function should look like: public function sendEmail($email, $subject, $message) { $config = Array( 'protocol' => 'smtp', 'smtp_host' => 'ssl://smtp.gmail.com', 'smtp_port' => 465, 'smtp_user' => 'xxx', 'smtp_pass' => 'xxx', 'mailtype' => 'html', 'charset' => 'iso-8859-1', 'wordwrap' => TRUE ); $this->load->library('email',$config); $this->email->set_newline("\r\n"); $this->email->from('noreply'); $this->email->to($email); $this->email->subject($subject); $this->email->message($message); // Return the result of the email send call return $this->email->send(); }

' 1 days')); $data = array( 'hash_key'=>$hash_string, 'hash_expiry'=>$hash_expiry, ); $this->model_forgotpass->updatePasswordhash($data,$email); $resetLink = base_url().'reset/password?hash='.$hash_string; $message = '<p>Your reset password Link is here:</p>'.$resetLink; $subject = "Password Reset link"; $sentstatus = $this->sendEmail($email,$subject,$message); if($sentstatus==true) { $this->model_forgotpass->updatePasswordhash($data,$email); $this->session->set_flashdata('success','Reset password link successfully sent'); redirect(base_url('forgotpass/index')); } else { $this->session->set_flashdata('error','Email sending error'); } } else { $this->session->set_flashdata('error','Invalid email id'); } } } else { $this->load->view('forgotpass/index','refresh'); } $this->load->view('forgotpass/index','refresh'); } public function sendEmail($email,$subject,$message) { $config = Array( 'protocol' => 'smtp', 'smtp_host' => 'ssl://smtp.gmail.com', 'smtp_port' => 465, 'smtp_user' => 'xxx', 'smtp_pass' => 'xxx', 'mailtype' => 'html', 'charset' => 'iso-8859-1', 'wordwrap' => TRUE ); $this->load->library('email',$config); $this->email->set_newline("\r\n"); $this->email->from('noreply'); $this->email->to($email); $this->email->subject($subject); $this->email->message($message); if($this->email->send()) { return true; } else { return false; } } this is my model: function validationemail($email) { if($email) { $sql = 'SELECT * FROM users WHERE email = ?'; $query = $this->db->query($sql, array($email)); $result = $query->num_rows(); return ($result == 1) ? true : false; } return false; } function updatePasswordhash($data,$email) { $this->db->where('email',$email); $this->db->update('users',$data); } i can't seem to identify the error here it always return as a Email sending error and i still can't received the mssage in my email although my username and password is correct but why i can't process it?

Q: In a shiny app how can I let the user choose the filename and directory to download with write.table This is a follow-up question to this Now I somehow managed to download the reactive dataframe to my hard drive (!not server or working directory) and append each new entry as new line with write.table. Interestingly write.csv does not work because it does not allow append argument https://stat.ethz.ch/pipermail/r-help/2016-August/441011.html. With this minimal working app, I would like to know how I can get the user to choose a directory and a filname to download there. Now I have this absolut path: file = "C:/Users/yourname/Downloads/my_df.csv" which works. But I don't know if it will work for other user! library(shiny) library(shinyWidgets) ui <- fluidPage( sidebarLayout( sidebarPanel(width = 4, sliderInput("a", "A", min = 0, max = 3, value = 0, width = "250px"), actionButton("submit", "Submit") ), mainPanel( titlePanel("Sliders"), tableOutput("values") ) ) ) server <- function(input, output, session) { sliderValues <- reactive({ data.frame(Name = c("A"), Value = as.character(c(input$a)), stringsAsFactors = FALSE) }) output$values <- renderTable({ sliderValues() }) # Save the values to a CSV file on the hard disk ---- saveData <- reactive({write.table(sliderValues(), file = "C:/Users/yourname/Downloads/my_df.csv", col.names=!file.exists("C:/Users/yourname/Downloads/my_df.csv"), append = TRUE) }) observeEvent(input$submit, { saveData() }) } shinyApp(ui, server) The requirement is that the user should see a modal dialog ui with the question "In which folder with which filename you want to download?". Quasi like the things we do daily if we download from the internet. A: I now solved it this way: I realized that I have two options: As suggested by @Stéphane Laurent using downloadhandler Using DT::datatable() I have decided to use number 2. Many thanks to all of your inputs! library(shiny) library(shinyWidgets) library(DT) ui <- fluidPage( sliderInput("a", "A", min = 0, max = 3, value = 0, width = "250px"), titlePanel("Sliders"), dataTableOutput("sliderValues", width="450px") ) server <- function(input, output, session) { sliderValues <- reactive({ df <- data.frame( Name = "A", Value = as.character(c(input$a)), stringsAsFactors = FALSE) %>% pivot_wider(names_from = Name, values_from = Value) return(df) }) # Show the values in an HTML table in a wider format---- output$sliderValues <- DT::renderDataTable({ DT::datatable(sliderValues(), extensions = c('Buttons'), options = list( dom = 'frtBip', buttons = list(list(extend = 'excel', filename = paste0("myname-", Sys.Date()))) ) ) }) } shinyApp(ui, server)

Q: How to find the position of a Rect in python? I was trying to make a code that moves a rect object (gotten with the get_rect function) but I need its coordinates to make it move 1 pixel away (if there are any other ways to do this, let me know.) Here is the code: import sys, pygame pygame.init() size = width, height = 1920, 1080 black = 0, 0, 0 screen = pygame.display.set_mode(size) ball = pygame.image.load("ball.png") rectball = ball.get_rect() while True: for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() rectball.move() screen.fill(black) screen.blit(ball, rectball) pygame.display.flip() You will notice that on line 11 the parameters are unfilled. This is because I was going to make it coords + 1. A: If I am correct I think it is rect.left or rect.top that gives it. Another method is to create another rectangle and check if the rectangle is in that. A: #To move a rect object in Pygame, you can use the move_ip() method. This method takes two arguments, the x and y coordinates to move the rect by. For example, if you want to move the rect one pixel to the right and one pixel down, you can use the following code: rectball.move_ip(1, 1) #You can also use the x and y attributes of the rect to move it by a certain amount. For example, if you want to move the rect one pixel to the right, you can use the following code: rectball.x += 1 #Note that this will only move the rect object and not the image that it represents. To move the image on the screen, you will also need to update the position of the ball surface using the blit() method. #Here is an updated version of your code that moves the rect and the image on the screen: import sys import pygame pygame.init() size = width, height = 1920, 1080 black = 0, 0, 0 screen = pygame.display.set_mode(size) ball = pygame.image.load("ball.png") rectball = ball.get_rect() while True: for event in pygame.event.get(): if event.type == pygame.QUIT: sys.exit() # Move the rect one pixel to the right and one pixel down rectball.move_ip(1, 1) # Update the position of the ball on the screen screen.blit(ball, rectball) pygame.display.flip()

Q: Selecting specific User I am trying to make an app that shows a users past expenses with C# querying a SQL Database. I have a program that shows the user their current expenses. They have to login using a unique username and password. When logged in, they should see only their expenses from the expenses table. I am currently using: Select * from ExpensesTbl Which shows everything, including other users information. I believe I need to use a WHERE clause, but I am unsure what it would look like as Im not sure what user is logged in. In example, table Expenses currently has two users (A and B). Can someone point me to how I can get just the information that pertains to only the logged user, instead of the information of all users? A: The solution for this is using IDs on each user, on ExpensesTbl create a Foreign Key that binds the ID with the information of this user on ExpensesTbl, then just do a SELECT * FROM WHERE ExpensesTbl.user_id = LoggedUser.id Please, take a read at those documents: https://www.w3schools.com/sql/sql_foreignkey.asp https://dev.mysql.com/doc/refman/5.6/en/create-table-foreign-keys.html

Q: Javascript onclick confirm form submit and flask app I want to add a confirmation to a form action: <form action="/delete" method="post"> <button id="deleteForm" class="btn btn-danger" onclick="deleteConfirm(this.form)">Delete</button> </form> And in my script.js I wrote the function: function deleteConfirm() { let text = "Are you sure?\nOk=Delete all data."; if (confirm(text) == true) { document.getElementById("deleteForm").submit(); } else { alert("Cancelled."); } } But with these codes when I click either ok or cancell, the form will submit. when I click cancel the alert show up but then the action /delete will execute. Is this an attribute of flask? Are there another ways to do this? A: prevent the form from being submitted when the user clicks "Cancel", you can add a return false; statement at the end of the deleteConfirm() function let text = "Are you sure?\nOk=Delete all data."; if (confirm(text) == true) { document.getElementById("deleteForm").submit(); } else { alert("Cancelled."); return false; } prevent the form from being submitted when the user clicks "Cancel", but it will still be submitted when they click "OK". EDIT : Wrap inside this one if still not working : function deleteConfirm() { let text = "Are you sure?\nOk=Delete all data."; if (confirm(text) == true) { return true; } else { alert("Cancelled."); return false; } } A: You need to add attribute type="button" to your button, and id "deleteForm" add to form <form id="deleteForm" action="/delete" method="post"> <button type="button" class="btn btn-danger" onclick="deleteConfirm(this.form)">Delete</button> </form> A: No need to use the onclick event of the button. Instead, attach type="submit" with your buttion. And add the onsubmit attribute with your form. This is the standard way of doing what you mentioned. function deleteConfirm(myForm) { let text = "Are you sure?\nOk=Delete all data."; if (confirm(text) == true) { return true; } else { alert("Cancelled."); return false; } } <form action="/delete" method="post" onsubmit="return deleteConfirm(this);"> <button id="deleteForm" type="submit" class="btn btn-danger">Delete</button> </form> A: There are like many ways to approach this question, but what i would do is that instead of having an entire javascript function just to display a on click alert i would just wrap it around a input. <input type="submit" value="Delete" onclick="return confirm('Are you sure you want to delete this data?')"> I have used this for like flask data delete and when the user clicks cancel it does not submit the form. Here is an example of what i just used: https://jsfiddle.net/12f6bvkq/

Q: How to use symlinks in React Native projet? The symlink support is still not officially available in react-native https://github.com/facebook/metro/issues/1. It's actually possible to use symlinks in the package.json with npm (not yarn) { "name": "PROJECT", "version": "0.1.0", "private": true, "scripts": { "start": "node node_modules/react-native/local-cli/cli.js start", "test": "jest" }, "dependencies": { "my_module1": "file:../shared/my_module1/", "my_module2": "file:../shared/my_module2/", "react": "16.8.3", "react-native": "0.59.5", }, "devDependencies": { "babel-jest": "24.7.1", "jest": "24.7.1", "metro-react-native-babel-preset": "0.53.1", "react-test-renderer": "16.8.3" }, "jest": { "preset": "react-native" } } Although we will get my_module1 does not exist in the Haste module map To fix this we could do before a metro.config.js (formerly rn-cli.config.js) const path = require("path") const extraNodeModules = { /* to give access to react-native-firebase for a shared module for example */ "react-native-firebase": path.resolve(__dirname, "node_modules/react-native-firebase"), } const watchFolders = [ path.resolve(__dirname, "node_modules/my_module1"), path.resolve(__dirname, "node_modules/my_module2"), ] module.exports = { resolver: { extraNodeModules }, watchFolders, transformer: { getTransformOptions: async () => ({ transform: { experimentalImportSupport: false, inlineRequires: false } }) } } Unfortunately it doesn't work anymore on react-native 0.59 The app is reloading, but changes in the source code are not reflected in the app. Anyone has a clue to achieve this? A: I had a similar issue and found haul. Follow haul getting started instructions. Add your local dependencies with file:../ e.g: // package.json "dependencies": { "name-of-your-local-dependency": "file:../" } reinstall node_modules with yarn --force Start the development server by yarn start (haul will replace your start script) Run react-native run-android or/and react-native run-ios A: None of the answers I found worked for me and it seems symlinks are not going to be supported anytime soon (see: https://github.com/facebook/metro/issues/1), so I had to do it manually. I am using onchange npm package and running that in my local package: onchange 'dist/**/*.js' -- cp -R ./dist ../../app/node_modules/@author/packagename That worked for me to achieve development and testing, while not breaking anything for production releases. I hope this can save my peers a few headaches. A: You can use yalc. Yalc will simulate a package publish without actually publishing it. Install it globally: npm i -g yalc In your local package: yalc publish In the application: yalc add package-name && yarn After you made some changes to the package, you can just run yalc push and it will automatically update every app that uses your local package A: After a few years working on this, we found a reliable way using yarn. Add your local dependencies with are inside a folder file:../CompanyPackages/package e.g: // package.json "dependencies": { "local-package": "file:../CompanyPackages/local-package" } Use a custom metro.config.js const path = require("path") const { mapValues } = require("lodash") // Add there all the Company packages useful to this app const CompanyPackagesRelative = { "CompanyPackages": "../CompanyPackages", } const CompanyPackages = mapValues(CompanyPackagesRelative, (relativePath) => path.resolve(relativePath) ) function createMetroConfiguration(projectPath) { projectPath = path.resolve(projectPath) const watchFolders = [...Object.values(CompanyPackages)] const extraNodeModules = { ...CompanyPackages, } // Should fix error "Unable to resolve module @babel/runtime/helpers/interopRequireDefault" // See https://github.com/facebook/metro/issues/7#issuecomment-508129053 // See https://dushyant37.medium.com/how-to-import-files-from-outside-of-root-directory-with-react-native-metro-bundler-18207a348427 const extraNodeModulesProxy = new Proxy(extraNodeModules, { get: (target, name) => { if (target[name]) { return target[name] } else { return path.join(projectPath, `node_modules/${name}`) } }, }) return { projectRoot: projectPath, watchFolders, resolver: { transform: { experimentalImportSupport: false, inlineRequires: true, }, extraNodeModules: extraNodeModulesProxy, }, } } module.exports = createMetroConfiguration(__dirname) A: Could never get my own environment working using any other suggestions, but found a hack that works well (though not ideal) that can be easily set up in just a few lines of code and without changing your RN project configuration. Use fs.watch for changes recursively in the directory where you're working on your library, and copy the updates over whenever there's been a change: import fs from 'fs' const srcDir = `./your-library-directory` const destDir = `../your-destination-directory` fs.watch("./src/", {recursive: true}, () => { console.log('copying...') fs.cp(srcDir, destDir, { overwrite: true, recursive: true }, function() { console.log('copied') }) })

Q: Insert the generated sequence into the Redshift table I ran into a problem with Redshift. I'm generating a sequence of dates and want to embed it in a table to work with the range. But Redshift only supports generation on the leader node. It is not possible to insert the data on the nodes. Nowhere in the documentation have I found information on how to insert the generated sequences into tables. Maybe someone has encountered such a problem and can share their experience in solving it? My sequence: SELECT date '2019-12-31' + INTERVAL AS date_range FROM generate_series(1, (date '2041-01-01' - date '2020-01-01')) INTERVAL; My query: CREATE TABLE public.date_sequence AS ( SELECT date '2019-12-31' + INTERVAL AS date_range FROM generate_series(1, (date '2041-01-01' - date '2020-01-01')) INTERVAL ); I also tried inserting data from cte. Insert data into a temporary table. The result is the same: ERROR: Specified types or functions (one per INFO message) not supported on Redshift tables. A: In amazon redshift you cant populate a table with data with create table you have to use a insert as far as I know, my suggestion would be something like this INSERT INTO public.date_sequence SELECT date '2019-12-31' + INTERVAL AS date_range FROM generate_series(1, (date '2041-01-01' - date '2020-01-01')) INTERVAL; A: Generate_series() is an unsupported function on Redshift. While it will still work on the leader node it is not a good idea to base your solutions on such functions. The better and supported approach is to use a recursive CTE - see https://docs.aws.amazon.com/redshift/latest/dg/r_WITH_clause.html I wrote up an example for making a series of dates in this answer - trying to create a date table in Redshift

Q: Is there a method to retrieve first empty row in a Google spreadsheet with API? I'm trying to retrieve the first empty row in a Google spreadsheet. I'm aware of the SpreadsheetApp class, however I'm using Google sheet's API (Rust). Is it possible to use something similar to getLastRow() with Spreadsheet API? A: Yes, you can use the Spreadsheet API to retrieve the first empty row in a Google Sheets spreadsheet. The API provides a getLastRow() method that returns the index of the last row that has content. You can then use this value to find the first empty row by incrementing the last row index by one. Here is an example of how to do this using the Rust library for the Google Sheets API: use google_sheets4::{spreadsheets::{GetSpreadsheetByDataFilterRequest, Sheets}, Range}; // Authenticate with the Google Sheets API and get a client instance let client = Sheets::new(...); // Set the ID of the spreadsheet to retrieve let spreadsheet_id = "spreadsheet_id"; // Set the range of the data to retrieve let range = Range { sheet_id: 0, start_row_index: 0, end_row_index: 0, start_column_index: 0, end_column_index: 0, }; // Create a request to retrieve the data from the specified range let req = GetSpreadsheetByDataFilterRequest { spreadsheet_id: spreadsheet_id.to_string(), ranges: vec![range], ..Default::default() }; // Send the request and retrieve the response let res = client.spreadsheets().get_by_data_filter(req).doit().

Q: How to embed RRULE JS Library in VMWare VRO task I'm trying to create a custom action in VMWare VRO which uses JS for its scripting logic. I'm trying to embed two libraries into a single code block so I can use them. Unfortunately, VRO doesn't use includes or the concept of libraries per se so it all has to be in the same giant script block. I'd like to use this RRULE JS library: https://github.com/conrad-vanl/rrule Which I can embed in one code block no problem. But it's dependent on the underscore library. https://github.com/jashkenas/underscore Which I can't seem to get to embed without throwing the following error: TypeError: Cannot read property "n" from undefined (unnamed script#2293) Which I'm guessing has something to do with the way the underscore library is formatted. Here is a gist with my current attempt at embedding both. https://gist.github.com/rsaturns/aceceabb87fc28879ffdb214425a2a15 If I can get both the RRULE and Underscore libraries to be embedded in the same file I think I will be able to get this working. A: VRO doesn't use a regular JavaScript engine such as the ones that run in the browser or server side Node.js . It uses the Rhino engine, which is based on Java, and as such it has a lot of quirky differences with regular JavaScript. There are quite a few differences in syntax and behavior compared to regular JS, so it can be expected that a lot of things that you think should work, will not work inside VRO. Some of the limitations that VRO js has: JS feature basically stop at ES5, but some features of ES5 aren't even implemented. Not all of the API is available inside VRO, and some objects, methods or functions have been replaced with an equivalent (Console.log is equivalent to System.log in VRO) You can't normally use external JS libraries such as axios, jQuery, lodash, etc... (you can try to get around this limitation a number of ways, which I'll explain) If you want to use an external library inside VRO, there are a few things to consider, but these are the most important: The JS version that the library is/depends on. The APIs and JS features that the library depends on. If your library is based on pre-ES5 JavaScript and does not use any special, browser-specific or node.js specific APIs, it should work out of the box inside VRO. If not, then you can try a few things to try to get it to work inside VRO: Use a transpiler (and bundler if you need) (such as Babel+Webpack, SWC, Esbuild, to name just a few) to downgrade the source code of the library you want to use into an older version of JS into a single JS file. You might need to use polyfills if you use some browser or Node.js APIs because they will not work inside VRO even when transpiled and downgraded. Put the resulting JS code into the same VRO workflow/action that you want to use it in and use it directly (I don't recommend this, as it can become a mess quite fast and is unreadable) Put the resulting JS code into a VRO resource element, then inside your VRO workflow/action , get the content of this resource element (it will be a string at this point) and use the eval() or the Function constructor to parse and evaluate the library code. It will then be available to use inside the rest of the workflow/action. (I recommend this method, since it is the least error prone, takes 1-3 lines of code only and is more readable) You could do the same thing, but additionnaly split the library code into as many smaller working modules/objects/functions as you want to have better performance and potentially work around VRO's limitations when working with huge files. This is what worked for me in general, but I can't guarantee that it will work in all cases. Because of the bizarre nature of the Rhino engine and limitations of VRO, you could run into other problems or limitations and won't be able to use the JS library that you want to use. For example, if your library code is too big, VRO will not be able to use it as it will run out of memory, or the workflow/action will crash, or it will just stop evaluating the library code midway and be useless. There are 2 other ways to use external libraries inside VRO workflows/actions, but they don't use the normal VRO engine. Just keep in mind that using this way, you cannot directly access all of the VRO APIs such as resource elements, plugins ,etc. So it has some limitations : Use the Node.js runtime of VRO instead of the default one (Rhino) to code your workflow/actions. You can use external and regular Node.js libraries such as lodash this way, without needing to transpile or bundle or downgrade it. (This is the best way to use external libraries, as they should work as you would expect normally in JS). There are 2 ways to do this and the documentation is quite useful in explaining in more details : https://docs.vmware.com/en/vRealize-Orchestrator/8.10/com.vmware.vrealize.orchestrator-using-client-guide.doc/GUID-13E3704E-A325-4CB1-AF57-45FEBDBBD159.html You can code a microservice or something that uses all the JS libraries you would need and expose them as a REST api in some server hosted somewhere, then call these endpoints from your VRO workflow/action.(This requires the most effort and is not really recommended for simple scripting) I hope this will help people that need to do something like this in the future, as it took me quite a while of trial and error to get to this point.

How to embed RRULE JS Library in VMWare VRO task

I'm trying to create a custom action in VMWare VRO which uses JS for its scripting logic. I'm trying to embed two libraries into a single code block so I can use them. Unfortunately, VRO doesn't use includes or the concept of libraries per se so it all has to be in the same giant script block. I'd like to use this RRULE JS library: https://github.com/conrad-vanl/rrule Which I can embed in one code block no problem. But it's dependent on the underscore library. https://github.com/jashkenas/underscore Which I can't seem to get to embed without throwing the following error: TypeError: Cannot read property "n" from undefined (unnamed script#2293) Which I'm guessing has something to do with the way the underscore library is formatted. Here is a gist with my current attempt at embedding both. https://gist.github.com/rsaturns/aceceabb87fc28879ffdb214425a2a15 If I can get both the RRULE and Underscore libraries to be embedded in the same file I think I will be able to get this working.

Q: How to catch keydown event inside child component There is a component that catches keyDown event. It has a counter which is incremented by Arrow Right and decremented by Arrow Left. export default function App() { const [position, setPosition] = React.useState(0); // eslint-disable-next-line consistent-return React.useEffect(() => { const keyboardHandler = (event) => { const key = parseInt(event.keyCode || event.which || 0, 10); switch (key) { case LEFT_ARROW: setPosition((p) => p - 1); break; case RIGHT_ARROW: setPosition((p) => p + 1); break; default: break; } }; window.document.addEventListener("keydown", keyboardHandler); return () => { window.document.removeEventListener("keydown", keyboardHandler); }; }, []); return ( <div className="App"> {position} <br /> <Inner /> </div> ); } It works fine. Now, there is a child component that has an input field. I would like it to catch arrow left and arrow right so it IS NOT propagated to the main component. My guess was: export default function Inner() { React.useEffect(() => { const keyboardHandler = (event) => { const key = parseInt(event.keyCode || event.which || 0, 10); switch (key) { case LEFT_ARROW: event.stopPropagation(); break; case RIGHT_ARROW: event.stopPropagation(); break; default: break; } }; window.document.addEventListener("keydown", keyboardHandler); return () => { window.document.removeEventListener("keydown", keyboardHandler); }; }, []); return <input name="test" />; } But it does not seem to work. The child receives the event AND the parent receives the event as well. I guess the problem is that the event handler is linked to the window.document, but how do I change it? Here is the codesandbox example: https://codesandbox.io/s/bold-pare-fvd305 Thank you in advance! A: You can ignore the keyDown if it was made inside the input field. You just need to check event.target: import "./styles.css"; import React from "react"; const LEFT_ARROW = 37; const RIGHT_ARROW = 39; export default function App() { const [position, setPosition] = React.useState(0); // eslint-disable-next-line consistent-return React.useEffect(() => { const keyboardHandler = (event) => { const key = parseInt(event.keyCode || event.which || 0, 10); if (event.target.name !== "test"){ switch (key) { case LEFT_ARROW: setPosition((p) => p - 1); break; case RIGHT_ARROW: setPosition((p) => p + 1); break; default: break; } }; } window.document.addEventListener("keydown", keyboardHandler); return () => { window.document.removeEventListener("keydown", keyboardHandler); }; }, []); return ( <div className="App"> {position} <br /> <input name="test" /> </div> ); }

Q: How to Disable and Enable WordPress Scrolling Using JS by Timer I have a question regarding Javascript Scrolling. How do I disable scrolling after visitors enter our website, then scrolling is active again 5-10 seconds later like the berakal.com site? I have got the JS on the website, but it is encrypted which is very difficult for me to decode. A: To disable scrolling on a website, you can use the overflow: hidden CSS property on the <body> element of the page. This will prevent the user from scrolling the page using their mouse or trackpad. To enable scrolling again after a certain amount of time, you can use a JavaScript timer to set a delay before removing the overflow: hidden property from the <body> element. Here is an example of how you might implement this: // Set the overflow property on the body element to prevent scrolling document.body.style.overflow = "hidden"; // Use a timer to enable scrolling after 5 seconds setTimeout(function() { document.body.style.overflow = "auto"; }, 5000); // 5000 milliseconds = 5 seconds This will disable scrolling on the page when the user first enters the website, then re-enable scrolling after 5 seconds. You can adjust the time delay to suit your needs.

Q: React Native: npm link local dependency, unable to resolve module I am developing a button ui package for react native. I try to build an example project to test this button. The directory structure is as follows: my-button/ package.json index.js example/ package.json index.js I try to use npm link: cd my-button npm link cd example npm link my-button In example/node_modules/ I can see my-button symlink, VSCode also can auto complete function in my-button package. But execute example app will show error: Unable to resolve module my-button ... Module does not exist in the module map or in these directories: ... But the path in the error message is correct. Don't know where I was wrong, or in React-Native have any special way to deal with link local dependency? I also tried npm install file:../.. It works fine in this way, but not easy to update dependency in example/ after I edited my-button. A: The npm link command doesn't work because React Native packager doesn't support symlinks. After a little research, I discovered that there are two ways to go about it. Use haul packager in the example app. Haul supports symlinks, so you can use npm link as usual. Use local dependency via file:../ and then edit files in node_modules folder or reinstall every time you make changes. I found Haul to work great for this use-case and even set-up a little starter project that also includes storybook, which is really helpful if you have many components to switch between. A: Try wml (https://github.com/wix/wml) It's an alternative to npm link that actually copies changed files from source to destination folders # add the link to wml using `wml add <src> <dest>` wml add ~/my-package ~/main-project/node_modules/my-package # start watching all links added wml start A: I couldn't always make it work with yarn link. What i found extra useful is yalc: First install it globally once forever: npm install -g yalc In the local library/package (i'll call it my-local-package), and run: yalc publish Then in your project which uses my-local-package as a dependency, run: (if you already have added it with any other way, first uninstall it (npm uninstall -S my-lockal-package) yalc add my-local-package npm install If my-local-package is a native module, then run react-native run-android to link the dependency. (or run-ios) If you make any change in the my-lockal-package, then: cd path/of/my-local-package yalc push //updates the local package cd path/to/my-project npm install react-native run-android (or run-ios) In case the update hasn't been applied, try to cd android && ./gradlew clean && cd .. and then rerun: react-native run-android. A: I'm having the same issue while developing a native module wrapper around an existing native SDK. At first I followed @aayush-shrestha's suggestion to install the package locally. Like this: npm install ../<package-folder> --save This works as long as I reference the module via NativeModules. Import it: import { NativeModules } from 'react-native'; And then access a module called ActualModuleName like this: NativeModules.ActualModuleName But it fails when I attempt to import the module by name: import { ActualModuleName } from 'react-native-actualmodulename' To make that work I had to first pack the package. Run this in the package's root directory: npm pack This generates a gzipped tarball: react-native-actualmodulename-1.0.0.tgz Now install that in your app: npm install <path/to>/react-native-actualmodulename-1.0.0.tgz An enormous downside to this is that you have to re-pack the package every time you make a change to the module. The only workaround I know of is to modify the package's files in node_modules directly and then copy those changes back to your repo when you're done. But the upside is that your app's source can import ActualModuleName the same way you'll import it once it's released via npm; no environment-specific code necessary. A: Ran into the same problem. While I could not make npm link work as it should, I worked around it by installing the local package in the project folder npm install ../<package-folder> --save This will install the package like a regular package but from the local folder. The downside is that the changes you make on the package will not be reflected. You will have to npm install after every change. A: You can use npm link using Metro. Just add the source folder of the linked package to watchFolders in your metro.config.js. A: Change your package.json //... "dependencies": { //... "my-button" : "file:../" }, //... A: I also came across this problem. After visiting the below link, I came to know that react- native does not support symlinks.[Click here][1] However, I have solved this by adding these lines in the metro.config.js file. Please replace your_module_name with your module name. const path = require('path'); const thirdPartyPath = path.resolve(__dirname + '/../your_module_name/'); // Path of your local module const thirdParty= { 'your_module_name': thirdPartyPath, }; const watchFolders = [ thirdPartyPath]; module.exports = { // existing dependencies resolver: { thirdParty, }, watchFolders }; A: I ran into the same problem. I tried to install a local module using npm, and kept running into the issue of not being able to resolve the module, even though I could see the folder in node_modules and autocomplete of class and method names worked. I was able to bypass it by installing the local library using yarn instead of npm after seeing this open issue on github. Issue was opened September 2020 and no comment from Facebook as of yet. A: This work for me: step 1 go to package: npm link packageNameHere This will link this package to global node_module step 2 go to directory which you want to use this package and run these npm link pathToPackageDirectory npm install pathToPackageDirectory ex: npm link ~/myDemoPackage This will link global node_moudle to this project If you want to import package to file, USE FILE PATH INSTEAD OF PACKAGE NAME ! ex: my package name is stripe-api-helper. my code are in src/index.ts then I need to resolve like this: import { postStripe, Item } from '@aliciaForDemo/stripe-api-helper/src' if u use '@aliciaForDemo/stripe-api-helper' it will fail. A: Could never get my own environment working using any other suggestions, but found a hack that works well (though not ideal) that can be easily set up in just a few lines of code and without changing your RN project configuration. Use fs.watch for changes recursively in the directory where you're working on your library, and copy the updates over whenever there's been a change: import fs from 'fs' const srcDir = `./your-library-directory` const destDir = `../your-destination-directory` fs.watch("./src/", {recursive: true}, () => { console.log('copying...') fs.cp(srcDir, destDir, { overwrite: true, recursive: true }, function() { console.log('copied') }) })

Q: Finding the minimum difference between elements in an array that are at least N indices apart I have an integer array with some finite number of values. My job is to find the minimum difference between any two elements in the array with indices that are separated by at least N spaces. Consider that the array contains: 4, 10, 11, 9, 17 and the constraint is a separation of 3 indices. The minimum difference would then be 5, coming from 9-4 What is an algorithm to solve this problem. I was thinking it was something similar to the closest pair algorithm, but not sure. Could that be applied here? A: Yes, you could use a variant of the closest pair algorithm to solve this problem. The key difference is that instead of looking for the minimum difference between any two elements in the array, you would only consider pairs of elements that are separated by at least N indices. Here's one way you could solve the problem: Sort the array in ascending order. Initialize a variable min_diff to the maximum possible value. Iterate over the elements in the array with an outer loop variable i. Within the outer loop, iterate over the elements in the array with an inner loop variable j. If the difference between i and j is less than N, skip this iteration of the inner loop. Otherwise, calculate the difference between the two elements and update min_diff if necessary. This algorithm has a time complexity of O(n^2), so it may not be suitable for large arrays. However, it is simple to implement and should work for small arrays. Another possible solution is to use a divide and conquer approach, similar to the one used in the closest pair algorithm. In this case, you would divide the array into two halves, find the minimum difference in each half, and then find the minimum difference between the two halves. This would have a time complexity of O(n log n), which is more efficient than the previous approach. You could also try using a sliding window approach, where you keep a window of size N and move it along the array, updating the minimum difference as you go. This would have a time complexity of O(n), which is the most efficient of the three approaches. However, it may be more difficult to implement.
