Stackoverflow Stackexchange Q: Can I manually set the value of a field annotated by @LastModifiedDate in java - spring? I have a java class that has a modifiedDate field which is annotated by @LastModifiedDate . In a particular case , I want to set the field of the "modifiedDate" manually , using the corresponding setter of that field before saving it into a mongo collection (using the org.springframework.data.repository.CrudRepository#save(java.lang.Object) ) I tried it by setting it using the corresponding setter but it did not work. I cannot further remove this annotation as in all other cases , this annotation is extremely helpful. Note : Please refer : http://ufasoli.blogspot.in/2017/01/spring-data-force-version-and.html . Here , using auditingHandler they are marking an object as modified even though it is not. I want it to be marked unmodified even if it is.

Stackoverflow Stackexchange Q: Spring boot JPA filter by join table I cant find something concrete in the docs (https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#jpa.query-methods.query-creation) and no satisfying answere in several blogs. so here my question. I have table Entity like: @Entity @Table(name = "workstation") public class Workstation { @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "userid", nullable = false) public User user; } And the user table Entity: public class user { @Id @GeneratedValue(strategy = IDENTITY) @Column(name = "ID", unique = true, nullable = false) public Integer id; @Column(name = "age", nullable = false) public int age } Now I would like to have a query in my Repository like this: public interface WorkstationRepo extends CrudRepository<Workstation, Long> { findByUserAgeLesserThan(int maxAge); } Means I want to find all user who are under a certain age through my Workstation Entity. And is it possible without a @Query annotation? Or/And how should it look like? A: Try this List<Workstation> findByUserAgeLessThan(int maxAge); Alternatively you can also write your query @Query("Select w from Workstation w where w.user.age < :maxAge") List<Workstation> findByUserAgeLesserThan(@Param("maxAge") int maxAge);

Stackoverflow Stackexchange Q: How to get the handle of curves plotted by contour3 in MATLAB? When I want to rotate the lines ploted using contour3, it seems like the graphic handles of the lines are already deleted. How can I get the handle of the contour lines? Or is it possible to rotate the lines with the contour matrix C? >> x = -2:0.25:2; x = -2:0.25:2; >> [X,Y] = meshgrid(x); >> Z = X.*exp(-X.^2-Y.^2); >> C=contour3(X,Y,Z,10,'m'); >> hd=gca; >> rotate(hd,[0 1 0],90,[0 0 0]); The lines did't move after entering the last command. (I'm using MATLAB 2016a.) A: You need to get the second output from contour3, which is the handle to the Contour graphics object: [C, h] = contour3(...); Unfortunately, this won't help you with your rotation problem. From the documentation for rotate: rotate(h,direction,alpha) rotates the graphics object h by alpha degrees. Specify h as a surface, patch, line, text, or image object. ... Note that rotate won't work on axes or Contour objects. Instead, you'll need to alter the camera view with view.

Stackoverflow Stackexchange Q: Computing training score using cross_val_score I am using cross_val_score to compute the mean score for a regressor. Here's a small snippet. from sklearn.linear_model import LinearRegression from sklearn.model_selection import cross_val_score cross_val_score(LinearRegression(), X, y_reg, cv = 5) Using this I get an array of scores. I would like to know how the scores on the validation set (as returned in the array above) differ from those on the training set, to understand whether my model is over-fitting or under-fitting. Is there a way of doing this with the cross_val_score object? A: You can use cross_validate instead of cross_val_score according to doc: The cross_validate function differs from cross_val_score in two ways - * *It allows specifying multiple metrics for evaluation. *It returns a dict containing training scores, fit-times and score-times in addition to the test score.

A: Why would you want that? cross_val_score(cv=5) does that for you as it splits your train data 10 times and verifies accuracy scores on 5 test subsets. This method already serves as a way to prevent your model from over-fitting. Anyway, if you are eager to verify accuracy on your validation data, then you have to fit your LinearRegression first on X and y_reg.

Stackoverflow Stackexchange Q: Remove duplicate items from list in C#, according to one of their properties I have list of class of type: public class MyClass { public SomeOtherClass classObj; public string BillId; } public List<MyClass> myClassObject; Sample Values: BillId = "123",classObj = {}, BillId = "999",classObj = {}, BillId = "777",classObj = {}, BillId = "123",classObj = {} So in above example, we have duplicate values for BillId. I would like to remove all the duplicate values (Not Distinct) so the result would contain only 999 & 777 value. One way to achieve this to * *Loop through all items *Get count of unique BillId *If count is greater than 1, store that BillId in another variable *Loop again and remove item based on BillId Is there any straightforward way to achieve this?

A: You can also do this, var result = myClassObject.GroupBy(x => x.BillId) .Where(x => !x.Skip(1).Any()) .Select(x => x.First()); FIDDLE A: I think this would work: var result = myClassObject.GroupBy(x => x.BillId) .Where(x => x.Count() == 1) .Select(x => x.First()); Fiddle here A: This may help. var result = myClassObject .GroupBy(x => x.BillId) .Where(x => x.Count()==1) .Select(x => x.FirstOrDefault()); A: The .Where(x => x.Count()==1) wasn't good for me. You can try: .GroupBy(x => x.codeLigne).Select(x => x.First()).ToList() A: Try this. var distinctList = myClassObject.GroupBy(m => m.BillId) .Where(x => x.Count() == 1) .SelectMany(x => x.ToList()) .ToList(); A: You've asked for a straightforward solution to the problem, and the GroupBy+Where+Select solutions satisfy perfectly this requirement, but you might also be interested for a highly performant and memory-efficient solution. Below is an implementation that uses all the tools that are currently available (.NET 6+) for maximum efficiency: /// <summary> /// Returns a sequence of elements that appear exactly once in the source sequence, /// according to a specified key selector function. /// </summary> public static IEnumerable<TSource> UniqueBy<TSource, TKey>( this IEnumerable<TSource> source, Func<TSource, TKey> keySelector, IEqualityComparer<TKey> comparer = default) { ArgumentNullException.ThrowIfNull(source); ArgumentNullException.ThrowIfNull(keySelector); Dictionary<TKey, (TSource Item, bool Unique)> dictionary = new(comparer); if (source.TryGetNonEnumeratedCount(out int count)) dictionary.EnsureCapacity(count); // Assume that most items are unique foreach (TSource item in source) CollectionsMarshal.GetValueRefOrAddDefault(dictionary, keySelector(item), out bool exists) = exists ? default : (item, true); foreach ((TSource item, bool unique) in dictionary.Values) if (unique) yield return item; } The TryGetNonEnumeratedCount+EnsureCapacity combination can have a significant impact on the amount of memory allocated during the enumeration of the source, in case the source is a type with well known size, like a List<T>. The CollectionsMarshal.GetValueRefOrAddDefault ensures that each key will be hashed only once, which can be impactful in case the keys have expensive GetHashCode implementations. Usage example: List<MyClass> unique = myClassObject.UniqueBy(x => x.BillId).ToList(); Online demo. The difference of the above UniqueBy from the built-in DistinctBy LINQ operator, is that the former eliminates completely the duplicates altogether, while the later preserves the first instance of each duplicate element.

Stackoverflow Stackexchange Q: How to join wagtail and django sitemaps? I'm using wagtail app in my Django project. Is it possible to join django sitemaps (https://docs.djangoproject.com/en/1.11/ref/contrib/sitemaps/) with wagtail sitemaps (wagtail.contrib.wagtailsitemaps)? Tried using django sitemap indexes, but it divide only django sitemap, how I can include wagtail sitemap? A: Wagtail uses the Django sitemap framework since version 1.10. This should allow you to easily combine regular Django sitemaps with Wagtail sitemaps. There is a small catch however; because wagtail supports multiple sites the sitemap should know for which site the sitemap is generated. For this reason wagtail provides it's own sitemap views (index and sitemap). These views extend the Django sitemap views in order to propagate the site object. So instead of importing the sitemap views from django: from django.contrib.sitemaps import views as sitemap_views Use the wagtail versions: from wagtail.contrib.wagtailsitemaps import views as sitemaps_views And then use the Django approach to map the urls to the views: from wagtail.contrib.wagtailsitemaps import Sitemap urlpatterns = [ # ... url(r'^sitemap\.xml$', sitemaps_views.index, { 'sitemaps': { 'pages': Sitemap }, 'sitemap_url_name': 'sitemap', }), url(r'^sitemap-(?P<section>.+)\.xml$', sitemaps_views.sitemap, name='sitemap'), # ... ] For a complete example you can see the code in the tests: https://github.com/wagtail/wagtail/blob/911009473bc51e30ff751fda0ea5d2fa1d2b450f/wagtail/tests/urls.py#L36

The exe file is 4577 kB which is almost 5Mb. How can I reduce its size or exclude some auto-bundled libraries? A: The .exe file you create using pyinstaller includes the python interpreter and all modules included in your script.Maybe, the modules you are using have a big library themselves. You can however try using py2exe but it might not work for all projects.The other way to get it smaller is to use a compression program as like, compress the executable using UPX (have a look at this:http://htmlpreview.github.io/?https://github.com/pyinstaller/pyinstaller/blob/v2.0/doc/Manual.html#a-note-on-using-upx). You can also try excluding some items too but at the discretion that removing such items doesn't interfere with the functionality of your .exe.

Create a virtual environment just for build purpose and install the packages you need in this environment. in your cmd execute these to create a virtual enviornment python -m venv build_env cd build_env C:\build_env\Scripts\Activate you will see this >>(build_env) C:\build_env Install all the packages you need for your script, start with pyinstaller pip install pyinstaller Once you are all installed, build the exe as before. The exe built using the virtual environment will be faster and smaller in size!! For more details check https://python-forum.io/Thread-pyinstaller-exe-size A: I had a similar problem and found a solution. I used Windows terminal preview. This program allows creation of various virtual environments like Windows Power Shell (btw. Linux Ubuntu too. Also, worth noting: you can have many terminals in this program installed and, even, open a few at once. Very cool stuff). Inside Windows Power Shell in Windows terminal preview I installed all the necessary libraries (like pandas etc.), then I opened the path to my file and tried to use this command: pyinstaller --onefile -w 'filename.py' ...but, the output exe didn't work. For some reason, the console said that there is a lack of one library (which I had installed earlier). I've found the solution in mimic the auto-py-to-exe library. The command used by this GUI is: pyinstaller --noconfirm --onedir --console "C:/Users/something/filename.py" And this one works well. I reduced the size of my output exe program from 911MB to 82,9MB!!! BTW: 911MB was the size of output made by auto-py-to-exe. I wonder how is it possible that no one yet has created a compressor that reads the code, checks what libraries are part of the code, then putting only them inside the compression. In my case, auto-py-to-exe probably loaded all libraries that I ever installed. That would explain the size of this compressed folder. Some suggest using https://virtualenv.pypa.io/en/stable/ but in my opinion, this library is very difficult, at least for me.

I've tried using mysqldump but each time I get ERROR 1227 (42000) at line 18: Access denied; you need (at least one of) the SUPER privilege(s) for this operation That because my root user that I use for this operation does not have SUPER privilege and I don't have access to change this. Is there a solution to do this without using mysqldump? Keep in mind that it's a pretty big database with over one hundred tables. A: You have to grant privilegies to the user: GRANT ALL PRIVILEGES ON database_name.* TO 'username'@'yourhost'; if you want to do it for all databases: GRANT SELECT ON *.* TO 'username'@'yourhost'; FLUSH PRIVILEGES;

A: I've made a bit more general function for this, because it's part of EDA protocol (Zuur et al., 2010). This article from Ariel Muldoon helped me. plotlist <- function(data, resp, efflist) { require(ggplot2) require(purrr) y <- enquo(resp) map(efflist, function(x) ggplot(data, aes(!!sym(x), !!y)) + geom_point(alpha = 0.25, color = "darkgreen") + ylab(NULL) ) } where: * *data is your dataframe *resp is response variable *efflist is a char of effects (independent variables) Of course, you may change the geom and/or aesthetics as it needs. The function returns a list of plots which you can pass to e.g. cowplot or gridExtra as in example: library(gridExtra) library(dplyr) # just for pipes plotlist(mtcars, hp, c("mpg","cyl","disp")) %>% grid.arrange(grobs = ., left = "HP")

A: this has happened to me before and I think what I did was literally go find the package's folder from file explorer on my computer and manually delete it A: I had the same trouble, so I try to delete packages by hand, but found I haven't root authority. Then I close R, and start it with sudo, try to remove packages again. However, it worked for me. A: Possible causes There could be many reasons as to why it is happening. In my case, remove.packages("somepackagehere") was not working because the current system user that I am using doesn't have write privileges to the packages I want to uninstall. So, this is a possible reason for computers/machines with multiple users using R. Checking the location of packages This can be checked by issuing the statement in the R console: .libPaths() output [1] "/Library/Frameworks/R.framework/Versions/4.0/Resources/library" The directory output may vary per R installation. This is just for my case. The directory output is where the installed packages were stored. It may look different for Windows systems. Checking privileges In Mac and Linux, the privileges can be checked by: cd /Library/Frameworks/R.framework/Versions/4.0/Resources/library ls -la output drwxrwxr-x 422 root admin 13504 Apr 21 19:13 . drwxrwxr-x 18 root admin 576 Jul 16 2020 .. drwxr-xr-x 3 mario admin 96 Jun 17 2021 RODBC drwxr-xr-x 3 mario admin 96 Jun 17 2021 dplyr In this case, it was mario who installed the packages. Since I --luigi-- was currently using the machine, I can not remove those packages. It is only mario that can do it. In Windows, I have no clue as to how it can be checked. Granting privileges cd /Library/Frameworks/R.framework/Versions/4.0/Resources/library sudo chown -R luigi:admin . OR cd /Library/Frameworks/R.framework/Versions/4.0/Resources/library sudo chmod -R o+w . In Windows, I have no clue as to how privileges can be granted. Removing packages Finally, with the correct privileges, you can now remove the packages like so: remove.packages("RODBC") A: Also had problems with remove.packages so deleting the folders as suggested by @sweetmusicality worked for me: #e.g. remove packages associated with tidyverse pkremove <- tools::package_dependencies("tidyverse", db = installed.packages())$tidyverse lapply(pkremove, function(x) { unlink(paste0(.libPaths()[1], "/", x), recursive = TRUE) })

Stackoverflow Stackexchange Q: Transfer Data From Apple Watch To iPhone in Swift I have been trying for multiple hours to find a way to send a global variable from the Apple Watch to the iPhone. There are a lot of questions abut transferring data from iPhone to Apple Watch but not vice versa in Swift 3. This is not a duplicate because I want to transfer data from the Apple Watch to iPhone, not vice Versa. How can I do this? A: Transferring data from Apple Watch to iPhone is very similar to vice versa. For global variable you probably should use updateApplicationContext() of WCSession: let session = WCSession.default() if session.activationState == .activated { session.updateApplicationContext(["my_global": g_myGlobal]) } On the iPhone you should assign delegate to the default WCSession and activate it. In the WCSessionDelegate, implement the following method: func session(_ session: WCSession, didReceiveApplicationContext applicationContext: [String : Any]) { let receivedGlobal = applicationContext["my_global"] as? TypeOfTheGlobal } Alternatively you can use sendMessage(_:replyHandler:errorHandler:) but this will require iPhone to be reachable. In general I would recommend you to follow Zak Kautz advice and read about WatchConnectivity. This is the most common way to communicate between watch and phone.

To achieve what you're trying, you'll need to first assign the result of split() to a variable you can then reference: var mydate = new Date(), myarr = mydate.toLocaleTimeString().split(':'); myarr.pop(); console.log(myarr.join(':')); A: if all you want to achieve is hours:minutes, you can just simply do this var mydate = new Date(); console.log(mydate.getHours() + ':' + mydate.getMinutes()); A: You are trying to use method chaining where next method in the chain uses the output of the previously executed method. Reason it's not working is because "join()" method is a prototype of an array but "pop()" returns an array element which doesn't aforementioned method that's why the error. refactor your code as below: var myDate = new Date(), myDateArr = myDate.toLocaleTimeString().split(':'); myDateArr.pop(); // Remove the seconds myDate = myDateArr.join(':'); // Returns string console.log(myDate); Hope this helps.

The suggestions themselves render ok, showing the groupName and groupDescription properties correctly, but after selection my input is just rendering the object rather than the 'groupName' field like I was hoping the [field] attribute would instruct. <p-autoComplete [(ngModel)]="groupSearchText" [suggestions]="groupResults" (completeMethod)="search($event)" [field]="groupName" [size]="30" [minLength]="3"> <template let-group pTemplate="item"> <div class="ui-helper-clearfix" style="border-bottom:1px solid #D5D5D5"> <div style="font-size:18px;margin:10px 10px 0 0">{{group.groupName}}</div> <div style="font-size:10px;margin:10px 10px 0 0">{{group.groupDescription}}</div> </div> </template> </p-autoComplete> A: Change [field]="groupName" to field="groupName" If you look at PrimeNG's doc, they dont use [] for field either.

Stackoverflow Stackexchange Q: How to quickly get the last line from a .csv file over a network drive? I store thousands of time series in .csv files on a network drive. Before I update the files, I first get the last line of the file to see the timestamp and then I update with data after that timestamp. How can I quickly get the last line of a .csv file over a network drive so that I don't have to load the entire huge .csv file only to use the last line? A: There is a nifty reversed tool for this, assuming you are using the built-in csv module: how to read a csv file in reverse order in python In short: import csv with open('some_file.csv', 'r') as f: for row in reversed(list(csv.reader(f))): print(', '.join(row)) In my test file of: 1: test, 1 2: test, 2 3: test, 3 This outputs: test, 3 test, 2 test, 1

A: Ensure that input string is UTF8. $var = "N°X"; print mb_detect_encoding($var); If you don't get UTF-8 out of this, convert it: $var = mb_convert_encoding($var, 'UTF-8'); And then your str_replace will work as intended. Another tool that might help you with encoding issues is xxd. php -r '$var = "N°X"; echo $var;' | xxd should return 00000000: 4ec2 b058 N..X which reveals the middle character is encoded as C2B0 hex, which is Unicode Character 'DEGREE SIGN' (U+00B0). fileformat.info comes handy now.

Stackoverflow Stackexchange Q: Add default collation to existing mongodb collection I'm trying to add a default collation to my mongodb collections. It's simple to create a new collection with a collation: db.createCollection(name, {collation:{locale:"en",strength:1}}) Unfortunately I looked through the docs and didn't see any db.updateCollection function. How am I supposed to add a collation without destroying and recreating all my documents in a new collection? A: From the collation specifications, After the initial release of server version 3.4, many users will want to apply Collations to all operations on an existing collection. Such users will have to supply the Collation option to each operation explicitly; however, eventually the majority of users wishing to use Collations on all operations on a collection will create a collection with a server-side default. We chose to favor user verbosity right now over abstracting the feature for short-term gains. So you know its not a option just yet.

A: There's one other option that works for my production needs: Execute mongodump on a collection mongodump --host hostname --port 32017 --username usr --password pwd --out c:\backup --db my_database --collection my_collection That will generate two files and one of them named my_collection.metadata.json. Open this file and modify options property according to MongoDB docs. { "options": { "collation": { "locale": "en", "strength": 1 } } ... } And then restore using mongorestore mongorestore --host hostname --port 32017 --username usr --password pwd --db contactstore c:\backup\my_database --drop From then on, any index you create will use that specific collation by default. Unfortunately, this requires a downtime window, so make sure you get one.

Stackoverflow Stackexchange Q: Common Lisp: relative path to absolute May be it is a really dumb question, but after playing around with all built-in pathname-family functions and cl-fad/pathname-utils packages I still can't figure out how to convert a relative path to absolute (with respect to $PWD): ; let PWD be "/very/long/way" (abspath "../road/home"); -> "/very/long/road/home" Where the hypothetical function abspath works just like os.path.abspath() in Python. A: The variable *DEFAULT-PATHNAME-DEFAULTS* usually contains your initial working directory, you can merge the pathname with that; (defun abspath (pathname) (merge-pathnames pathname *default-pathname-defaults*)) And since this is the default for the second argument to merge-pathnames, you can simply write: (defun abspath (pathname) (merge-pathnames pathname))

One of the many functions defined in the library is uiop:parse-unix-namestring, which understands the syntax of Unix filenames without checking if the path designates an existing file or directory. However the double-dot is parsed as :back or :up which is not necessarily supported by your implementation. With SBCL, it is the case and the path is simplified. Note that pathnames allows to use both :back and :up components; :back can be simplified easily by looking at the pathname only (it is a syntactic up directory), whereas :up is the semantic up directory, meaning that it depends on the actual file system. You have a better chance to obtain a canonical file name if the file name exists. Truename You can also call TRUENAME, which will probably get rid of the ".." components in your path. See also 20.1.3 Truenames which explains that you can point to the same file by using different pathnames, but that there is generally one "canonical" name. A: Here's the final solution (based on the previous two answers): (defun abspath (path-string) (uiop:unix-namestring (uiop:merge-pathnames* (uiop:parse-unix-namestring path-string)))) uiop:parse-unix-namestring converts the string argument to a pathname, replacing . and .. references; uiop:merge-pathnames* translates a relative pathname to absolute; uiop:unix-namestring converts the pathname back to a string. Also, if you know for sure what kind of file the path points to, you can use either: (uiop:unix-namestring (uiop:file-exists-p path)) or (uiop:unix-namestring (uiop:directory-exists-p path)) because both file-exists-p and directory-exists-p return absolute pathnames (or nil, if file does not exist). UPDATE: Apparently in some implementations (like ManKai Common Lisp) uiop:merge-pathnames* does not prepend the directory part if the given pathname lacks ./ prefix (for example if you feed it #P"main.c" rather than #P"./main.c"). So the safer solution is: (defun abspath (path-string &optional (dir-name (uiop:getcwd))) (uiop:unix-namestring (uiop:ensure-absolute-pathname (uiop:merge-pathnames* (uiop:parse-unix-namestring path-string)) dir-name)))

Stackoverflow Stackexchange Q: Static imports in swift In java you can do import static MyClass and you'll be able to access the static methods of MyClass without having to prepend them with the class name: myMethod() instead of MyClass.myMethod() Is there a way to do this in swift? A: I don´t think you can import a static class like Java, it´s a traditional static in Swift where you call it by class name + variable/function. class MyClass { static let baseURL = "someURl" static func myMethod() { } } MyClass.baseURL or MyClass. myMethod. What you can do is to add a typealias to make an alias for your Static class. private typealias M = MyClass And then use the following: M.baseURL or M.myMethod.

Stackoverflow Stackexchange Q: ngIf - else vs two ngIf conditions Consider the following code sample: <div *ngIf="condition; else elseBlock"> <!-- markup here --> </div> <ng-template #elseBlock> <div> <!-- additional markup here --> </div> </ng-template> Another way I can achieve the same functionality is: <div *ngIf="condition"> <!-- markup here --> </div> <div *ngIf="!condition"> <!-- additional markup here --> </div> I want to know specific reasons for which of these two ways should be used and why? A: The first solution is better. Although both achieve the same thing, the first is cleaner and easier to follow logically. You only do one check with the first solution. This is a good solution because: * *It takes time to evaluate a condition. *By using else, you only have to check once. In your second solution you check if a condition is met (which takes time), and then you check if the not of the same condition is met. *Using else allows you to have an action to do in the case that somehow neither of the conditions are met. EDIT: See @toazaburo's answer, which addresses unsafeness.

EDIT: See @toazaburo's answer, which addresses unsafeness. A: Using else lets you avoid writing the condition twice, which could be a source of bugs, so I would use that preferentially. You can also put the else template down at the bottom of your template if you so choose, which can make the template easier to read. If you are unwrapping an observable with the async pipe, then it is much easier to write <div *ngIf="myItems$ | async as myItems; else noItemsYet"> than to add another <div *ngIf="!(myitems | async)">, which would also force Angular to create another internal subscription. Those voting to close this question as a matter of opinion are misguided. The fact that people might have different opinions on something does not mean that there are not valid points that are worth putting forward. If using else was a matter of mere preference, I doubt the Angular developers would have prioritized it for Angular 4 as they did. As @Ishnark points out, there may be performance implications as well.

Stackoverflow Stackexchange Q: How to use tag in Android I need to know how to use layout tag in android xml file. I know it is used for data binding but I do not have complete knowledge on this. Please let me know if anyone can help me in same. Thanks in Advance !! A: The <layout> tag must be the root tag when you are using DataBinding. Doing so you are telling the compiler that you are using DataBinding and your layout will have special tags like <variable> or <import>, so you have to embed your layout within that tag. In short, you need to use the <layout> tag whenever you are using DataBinding for the compiler to understand the special tags and generate the DataBinding class with the right variables and methods. If you have a layout like this (layout_data_binding.xml): <layout xmlns:android="http://schemas.android.com/apk/res/android"> <data> <variable name="user" type="com.example.User"/> </data> <LinearLayout android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@{user.firstName}"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@{user.lastName}"/> </LinearLayout> </layout> It is based on what is inside the <layout> tag to create the LayoutDataBinding class (auto-generated) with the User variable and its getters and setters.

Stackoverflow Stackexchange Q: Is it possible to use Metal shader code in an iPad Swift Playground? Is it possible to use custom Metal shader code in an iPad Swift Playground? If so, how does one get the *.metal file or code (or its pre-compiled object) onto an iPad to use with a Playground and Swift code? Is the use of Xcode on a Mac required to help? (this question is not about using the built-in performance shaders, or about running stuff in a Playground on a Mac) A: You have two options: either create an iOS playground in Xcode and send it to your iPad but then you are not allowed to edit the .metal file, just read it, like in this example; or you can create your shaders file as a multiline string (now possible in Swift 4 and Xcode 9 beta) and create your library from that string. A more cumbersome way is to concatenate string lines in Xcode 8/Swift 3 like in this example.

I tried using the integrated code coverage plugin of IntelliJ, Emma, and JaCoCo, but none of them give me any results. I have already searched on StackOverflow, but all results I get are either with third-party tools, changing some configuration with my tomcat server + maven (I don't know much about these topics) and again JaCoCo (which doesn't work for me).

The steps I take are: source activate myenv conda install ipython ipython When I am in ipython interactive shell, it calls python from the anaconda root bin. (~/anaconda2/bin') Is there anything I can do to change the python path to ~/anaconda2/envs/myenv/bin and import packages from myenv? I see few solutions to making env work in jupyter when I search the web, but no answer on making it work on the interactive shell. A: This is likely due to your $PATH variable being messed up. THe easiest way to make sure you get IPython from within an env is to use $ python -m IPython <rest of the options> to start IPython. This works for many of the Python installable application; like pytest, pip and other.

Stackoverflow Stackexchange Q: How to run unit tests against an app using an embedded framework without x86_x64 We need to integrate into our iOS app a framework that doesn't target x86_x64. We don't have access to that framework source code and we've been informed that they would release it for that architecture in a couple of months. Meanwhile our unit test target doesn't compile with the following linker error: ld: framework not found FrameworkName for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) I've tried adding an linker flag for Any iOS Simulator SDK with the value -weak_framework FrameworkName. By doing so we can run the app on simulator but the test target crash with the same linker error. Any idea how to setup the build settings/phase so that we can run our unit test suite? Thanks! Also note that we need to add that framework as an embedded binaries.

I still confuse with how to implement k-fold cross validation in my neural network. I wish you guys can help me out. My code is as follow: import numpy as np from sklearn.model_selection import KFold from sklearn.neural_network import MLPClassifier f = open("seeds_dataset.txt") data = np.loadtxt(f) X=data[:,0:] y=data[:,-1] kf = KFold(n_splits=10) X_train, X_test, y_train, y_test = X[train], X[test], y[train], y[test] clf = MLPClassifier(solver='lbfgs', alpha=1e-5, hidden_layer_sizes=(5, 2), random_state=1) clf.fit(X, y) MLPClassifier(activation='relu', alpha=1e-05, batch_size='auto', beta_1=0.9, beta_2=0.999, early_stopping=False, epsilon=1e-08, hidden_layer_sizes=(5, 2), learning_rate='constant', learning_rate_init=0.001, max_iter=200, momentum=0.9, nesterovs_momentum=True, power_t=0.5, random_state=1, shuffle=True, solver='lbfgs', tol=0.0001, validation_fraction=0.1, verbose=False, warm_start=False) A: In case you are looking for already built in method to do this, you can take a look at cross_validate. from sklearn.model_selection import cross_validate model = MLPClassifier() cv_results = cross_validate(model, X, Y, cv=10, return_train_score=False, scoring=model.score) print("Fit scores: {}".format(cv_results['test_score'])) The thing I like about this approach is it gives you access to the fit_time, score_time, and test_score. It also allows you to supply your choice of scoring metrics and cross-validation generator/iterable (i.e. Kfold). Another good resource is Cross Validation.

It also allows you to supply your choice of scoring metrics and cross-validation generator/iterable (i.e. Kfold). Another good resource is Cross Validation. A: Kudos to @COLDSPEED's answer. If you'd like to have the prediction of n fold cross-validation, cross_val_predict() is the way to go. # Scamble and subset data frame into train + validation(80%) and test(10%) df = df.sample(frac=1).reset_index(drop=True) train_index = 0.8 df_train = df[ : len(df) * train_index] # convert dataframe to ndarray, since kf.split returns nparray as index feature = df_train.iloc[:, 0: -1].values target = df_train.iloc[:, -1].values solver = MLPClassifier(activation='relu', solver='adam', alpha=1e-5, hidden_layer_sizes=(5, 2), random_state=1, verbose=True) y_pred = cross_val_predict(solver, feature, target, cv = 10) Basically, the option cv indicates how many cross-validation you'd like to do in the training. y_pred is the same size as target. A: Do not split your data into train and test. This is automatically handled by the KFold cross-validation. from sklearn.model_selection import KFold kf = KFold(n_splits=10) clf = MLPClassifier(solver='lbfgs', alpha=1e-5, hidden_layer_sizes=(5, 2), random_state=1) for train_indices, test_indices in kf.split(X): clf.fit(X[train_indices], y[train_indices]) print(clf.score(X[test_indices], y[test_indices])) KFold validation partitions your dataset into n equal, fair portions. Each portion is then split into test and train. With this, you get a fairly accurate measure of the accuracy of your model since it is tested on small portions of fairly distributed data.

Stackoverflow Stackexchange Q: use docker for google cloud data flow dependencies I am interested in using Google cloud Dataflow to parallel process videos. My job uses both OpenCV and tensorflow. Is it possible to just run the workers inside a docker instance, rather than installing all the dependencies from source as described: https://cloud.google.com/dataflow/pipelines/dependencies-python I would have expected a flag for a docker container, which is already sitting in google container engine. A: 2021 update Dataflow now supports custom docker containers. You can create your own container by following these instructions: https://cloud.google.com/dataflow/docs/guides/using-custom-containers The short answer is that Beam publishes containers under dockerhub.io/apache/beam_${language}_sdk:${version}. In your Dockerfile you would use one of them as base: FROM apache/beam_python3.8_sdk:2.30.0 # Add your customizations and dependencies Then you would upload this image to a container registry like GCR or Dockerhub, and then you would specify the following option: --worker_harness_container_image=$IMAGE_URI And bing! you have a customer container. It is not possible to modify or switch the default Dataflow worker container. You need to install the dependencies according to the documentation.

It is not possible to modify or switch the default Dataflow worker container. You need to install the dependencies according to the documentation. A: If you have a large number of videos you will have to incur the large startup cost regardless. Thus is the nature of Grid Computing in general. The other side of this is that you could use larger machines under the job than the n1-standard-1 machines, thus amortizing the cost of the download across less machines that could potentially process more videos at once if the processing was coded correctly. A: One solution is to issue the pip install commands through the setup.py option listed for Non-Python Dependencies. Doing this will download the manylinux wheel instead of the source distribution that the requirements file processing will stage.

Stackoverflow Stackexchange Q: how to Change font size, Without changing the size of button in CSS In the following code I want to change just inner font size not the button size. <html> <head> <style> .sm { font-size:x-small; } </style> </head> <body> <button class="sm">submit</button> </body> </html> A: To change the text size without changing the button size, you would need to fix the size of the button. This can be done using height and width in CSS. That way you can change the font-size without having it affect the button size. Take a look at my code below. As you can see, with the height and width changed, the button is now a fixed size. This is proven by the text being larger than the button. CSS button { font-size: 30px; height: 60px; width: 60px; } HTML <button> Hello </button>

A: Another method to achieve this would be to take advantage of the 3rd dimension. This method does not require you to fix the size of your button and allows it to still adapt to the content size. It would also scale any svg or other content you put in the button to provide a nice hover pop effect. HTML <button> <div> Button Text </div> </button> CSS button div { -webkit-transition: -webkit-transform 0.14s ease; } button:hover div { -webkit-transform: perspective(100px) scale(1.05); } button:active div { -webkit-transform: perspective(100px) scale(1.08); } I am not sure this is what your trying to achieve but I think its a neat solution and I thought I'd share it in case anyone else want to try it.

Stackoverflow Stackexchange Q: Equating symbolic coefficients I would like to seek y particular of ODE y'' - y' - 2y = 4x^2 I made the following script: syms x A0 A1 A2 ypa = A2*x^2+A1*x+A0; % y_p assume cyp = diff(ypa,2) - diff(ypa) - 2*ypa % according to ODE P1 = 4*x^2; P2 = cyp ; % Equating P1 and P2 C = coeffs(P1 - P2,x); A0 = solve(C(1),A0) A1 = solve(C(2),A1) A2 = solve(C(3),A2) I got the correct answer for A2 = -2. But I did not get for A0 (should be -3) and A1 (should be 2). How to get them automatically? P.S I'm using MATLAB R2013a. A: Instead of calling solve 3 times, once on each equation of C, you should call it once on the entire system of equations so that the proper substitutions are done to give you a numeric result for each variable: >> [A0, A1, A2] = solve(C) A0 = -3 A1 = 2 A2 = -2

Stackoverflow Stackexchange Q: reserve array memory in advance in Julia How can we reserve memory (or allocate memory without initialization) in Julia? In C++, a common pattern is to call reserve before calling push_back several times to avoid having to call on malloc more than once. Is there an equivalent in Julia? A: I think you are looking for sizehint! help?> sizehint! search: sizehint! sizehint!(s, n) Suggest that collection s reserve capacity for at least n elements. This can improve performance.

Stackoverflow Stackexchange Q: Why would one want to use string.Format with only one parameter? I encountered the following code string in a project's code: var result = string.Format(source); with variable 'source' being a string I can't understand what useful this line is doing. As I always thought, we need at least two parameters for string.Format method to have some useful output. ReSharper is not highlighting this as a something redundant so it seems that this line might have some purpose which I can't grasp at the moment. (Or maybe ReSharper just doesn't handle this case specifically) Why would one want to use string.Format with only one parameter? A: Perhaps the overloaded function public static string Format(string format, params object[] args); is allowing that code to compile. I cann't imagine that string.Format(source) would be helping in any meaningful way.

Object { "Check 1": Object { "valid": false }, "Check 2": Object { "valid": false } } I am not sure if there is a syntax error in this code. I tried selecting all the presets in babeljs but it does't compile properly. A: Object spread is stage 4 proposal and isn't part of existing specifications. Stage 3 preset should be enabled in Babel, namely, transform-object-rest-spread. There are syntax errors in the code above that will prevent it from being compiled properly even with required presets. It should be let checks = checkList .reduce((acc, check) => ({...acc, [check]: {valid: false}}), {});

There are syntax errors in the code above that will prevent it from being compiled properly even with required presets. It should be let checks = checkList .reduce((acc, check) => ({...acc, [check]: {valid: false}}), {}); A: First of all you don't have wrap the properties in an extra object (unless you also want to use the spread operator on that). So {...acc, {[check]: {valid: false}}} can become {...acc, [check]: {valid: false}} This means you're adding an object to accumulator. The key of this object is the name you assigned it (Check[n]) and the values are the ones you set ({valid...}). Secondly, as far I know, you cannot use the spread operator without explicitly a new value. So you should either write your state on a new line like: let checks = checkList.reduce((acc, check) => { return {...acc, [check]: {valid: false}} }, {}) Or wrap it in extra parentheses: let checks = checkList.reduce((acc, check) => ({...acc, [check]: {valid: false}}) , {})

A: Fetch from your upstream, checkout to that branch, then force push to that branch on your fork. git fetch upstream git checkout <target branch> git push -f origin <target branch> Disclaimer: I haven't tested this. A: First you need to configure a remote for a the original repo. $ git remote add upstream https://github.com/ORIGINAL_OWNER/ORIGINAL_REPOSITORY.git $ git fetch upstream Now you can use any git command with any branch from the original repo. $ git checkout master $ git pull upstream master Of course, you can checkout any other branch than master. $ git checkout my-radical-new-feature $ git pull upstream master Typically I pull directly to my local master branch as shown here and then merge the local master into other branches where I am working. $ git checkout master $ git pull upstream master $ git checkout my-radical-new-feature $ git merge master See the GitHub docs for more details

A reduced version of my data: aa <- data.frame(a=c(1:4),b=c("Fisheries, Fisheries, Geography, Marine Biology", "Fisheries", "Marine Biology, Marine Biology, Fisheries, Zoology", "Geography")) I want to convert column b into a unique list of elements, i.e., remove the duplicates, so that the end result is a b 1 Fisheries, Geography, Marine Biology 2 Fisheries 3 Marine Biology, Fisheries, Zoology 4 Geography I am able to do this for individual elements of the list, for example, using unique(unlist(strsplit(aa[1]))) BUT only on individual elements, not the entire column (otherwise it returns a single unique list for the entire column). I can’t figure out how to do this for the entire list, one element at a time. Maybe with lapply and write my own function for *unique(unlist(strsplit()))? Many thanks!

Stackoverflow Stackexchange Q: Is there a way to get F#'s constructor-parameters-are-automatically-immutable-private-members feature in C#? In F#, the constructor parameters are automatically saved as immutable fields in the class without having to write the declaration of the field or the copying of the constructor parameter to the field in the constructor. Is there any way to mimic this functionality in C#? Is there a reason why a future version of C# couldn't have this feature (i.e. is there some fundamental limitation of the existing language that conflicts with this feature)? A: The C# equivalent will be records. These are currently earmarked for C# 8, but there's no guarantees (especially as they were proposed for C# 6 & 7 too and were delayed in both cases).

If I right-click on any of the outgoing links, and select "open link" or "open in new window", the links will open. I've also created a handler for navigation requests using "decide-policy" signal and "create" signal, in the hopes of retrieving the uri, however in request object the uri is blank. This seems to be a problem with webview and gmail/inbox in general as discussed here. The previous question hasn't been solved, therefore I'm asking again but in the context of Python.

Is that cause the issue? A: I have built a demo to test it, but it didn't occur. So I rechecked my code and found I put some work in DispatchQueue.main.async which block the UI and cause the problem.

A: I performed test especially for you and following code works for me: override func viewDidLoad() { super.viewDidLoad() DispatchQueue.main.async { MBProgressHUD.showAdded(to: self.navigationController!.view, animated: true) } } so the problem is somewhere else located A: The root UIView geometry is not being calculated(viewDidLayoutSubviews is not called) at the point of viewDidLoad. I'd recommend putting your code into viewDidAppear. Also, no need to explicitly call it inside DispatchAsync.main, as other mentioned it is being called in the UI thread unless you want to call it from the background thread. A: Actually MBProgressHUD works on UI main thread and you are trying to call it in background thread. Try this:- override func viewDidLoad() { super.viewDidLoad() DispatchQueue.main.async { start() } } func start(){ MBProgressHUD.showAdded(to: self.navigationController!.view, animated: true)}

Stackoverflow Stackexchange Q: Is the constructor still needed in React with autobinding and property initializers I am refactoring an es6 class based React component that uses the normal constructor, and then binds methods, and defines state/attributes within that constructor. Something like this: class MySpecialComponent extends React.Component { constructor(props) { super(props) this.state = { thing: true } this.myMethod = this.myMethod.bind(this) this.myAttribute = { amazing: false } } myMethod(e) { this.setState({ thing: e.target.value }) } } I want to refactor this so that I am autobinding the functions, and using property initializers for the state and attributes. Now my code looks something like this: class MySpecialComponent extends React.Component { state = { thing: true } myAttribute = { amazing: false } myMethod = (e) => { this.setState({ thing: e.target.value }) } } My question is, do I still need the constructor? Or are the props also autobound? I would have expected to still need the constructor and included super(props), but my code seems to be working and I'm confused. Thanks A: You don't need an explicitly defined constructor unless you need to reference the props in your initial state object.

Thanks A: You don't need an explicitly defined constructor unless you need to reference the props in your initial state object. A: You don't need to define a constructor explicitly , and then do super(props).You can access the props as in the example below. i.e. 'prop1' class MySpecialComponent extends React.Component { state = { thing: true , prop1:this.props.prop1 } myAttribute = { amazing: false } myMethod = (e) => { this.setState({ thing: e.target.value }) } render(){ console.log(this.state.prop1); return( <div>Hi</div> ); } } ReactDOM.render(<MySpecialComponent prop1={1}/> , mountNode); A: From my understanding, you don't need to type out a constructor at all when using class properties (as in your second code example). The accepted answer states that you do need one if you "need to reference the props in your initial state object," but if you're using said class properties, then you're probably using Babel to transpile it, in which case a constructor is used, it's just being done behind the scenes. Because of this, you don't need to add a constructor yourself, even if you are using props in state. See this aricle for better examples and a better explanation.

Stackoverflow Stackexchange Q: Access to store.dispatch in a saga for use with react router redux I'm currently refactoring a react + redux + saga + react-router 3 application to use the new react-router 4 due to breaking changes. Before I would use browserHistory to direct to an appropriate path based on the results from a saga. Due to react-router 4 changes, I can't use browserHistory any longer. Now I've incorporated react-router-redux to essentially do what browserHistory did. The problem is that react-router-redux only works within a store.dispatch, e.g. store.dispatch(push('/')). I can't seem to find a way to access either the store or it's dispatch function inside my sagas. Any ideas on how to access store.dispatch within a saga? I know you can pass arguments in the root saga but I don't know how to retrieve them in my actual sagas. A: Use redux-saga's put effect, which dispatches redux actions to the store - docs. import { call, put } from 'redux-saga/effects' // ... function* fetchProducts() { const products = yield call(Api.fetch, '/products') // create and yield a dispatch Effect yield put({ type: 'PRODUCTS_RECEIVED', products }) }

Q: Access to store.dispatch in a saga for use with react router redux I'm currently refactoring a react + redux + saga + react-router 3 application to use the new react-router 4 due to breaking changes. Before I would use browserHistory to direct to an appropriate path based on the results from a saga. Due to react-router 4 changes, I can't use browserHistory any longer. Now I've incorporated react-router-redux to essentially do what browserHistory did. The problem is that react-router-redux only works within a store.dispatch, e.g. store.dispatch(push('/')). I can't seem to find a way to access either the store or it's dispatch function inside my sagas. Any ideas on how to access store.dispatch within a saga?

Stackoverflow Stackexchange Q: Boundary points from a set of coordinates I have a set of lat,long points, and from this points I'd like to extract the points that form the boundaries, I've used convexhull, but for my purpouse is not enough as convehull just returns the most distant points that form the polygon where all the points fit, I need ALL the points that form the peremiter, something like the image I've attached. What could I do? Is there some kind of package ready to use instead of implement any spatial algorithm? Thanks A: You must use a package for convex polygons. Here is an example: import alphashape import matplotlib.pyplot as plt points = put your points here (can be array)! alpha = 0.95 * alphashape.optimizealpha(points) hull = alphashape.alphashape(points, alpha) hull_pts = hull.exterior.coords.xy fig, ax = plt.subplots() ax.scatter(hull_pts[0], hull_pts[1], color='red')

Stackoverflow Stackexchange Q: Will go test code only referenced in test files be compiled into the binary? I am wondering what code will be compiled into the go binary if you compile a binary using go build ./... . This will compile a binary that has a cli program. For this cli program, I have test code and non test code. I currently have several flavours of test code: * *foo_test.go in package foo_test *foo_internal_test.go in package foo *testutil.go in package testutil that provides test utility functions No test code is actually referenced in the non test code. The testutil functions are only imported in the test files. If the test code is infact compiled into the binary , how much of a problem is this? A: I believe that if you have an init() function in an otherwise unreachable file, it will still be linked into the executable. _test.go files would be still excluded. This bit us when we had some test helper code that was not in _test files. One had an init() function which ran on the executable startup.

A: A go binary only includes code reachable from its main() entry point. For test binaries main() is the test runner. As to "how much of a problem" it is if it were included... none. It would increase the binary size and compilation time somewhat but otherwise have no impact - code that isn't executed, by definition, does nothing.

Stackoverflow Stackexchange Q: How can i sort semantic versions in pandas? I have a list of software releases as versions. The software follows the semantic version specification, meaning there is a major version, a minor version and patch versions: * *0.1 *0.2 *0.2.1 *0.3 *... *0.10 *0.10.1 Is there a way in pandas to sort these versions so that 0.2 is bigger than 0.1 but smaller than 0.10? A: You can use the standard distutils for this! from distutils.version import StrictVersion versions = ['0.1', '0.10', '0.2.1', '0.2', '0.10.1'] versions.sort(key=StrictVersion) Now it's sorted like this: ['0.1', '0.2', '0.2.1', '0.10', '0.10.1'] Source

So for now there is two sort functions in pandas, sort_values and sort_index, neither of them have a key parameter for us to pass a custom sort function to it. See this github issue. jezrael's answer is very helpful and I'll build my solution based on that. df['ver'] = sorted(df['ver'], key=StrictVersion) is useful only if the verion column is the single column in the DataFrame, otherwise we need to sort the other columns following the version column. jezrael reindex the DataFrame, because the wanted index order can be obtained by the buitin sorted function, who does have a key parameter. But, what if the version is not the index and I don't want to set_index('ver')? We can use apply to map the original version string to a StrictVersion object, then sort_values will sort in the wanted order: from distutils.version import StrictVersion df['ver'] = df['ver'].apply(StrictVersion) df.sort_values(by='ver') A: You can come up with something like that: for module, versions in result.items(): result[module] = sorted( versions, key=lambda x: mixutil.SemVersion(x.version), reverse=True )

I checked the source code and its doing the parsing and stringifing before you get or set respectively.I have not tested it but you should be able to do the following: import { LocalStorageModule } from 'angular-2-local-storage'; @NgModule({ imports: [ LocalStorageModule.withConfig({ prefix: 'my-app', storageType: 'localStorage' }) ], declarations: [ .. ], providers: [ .. ], bootstrap: [AppComponent] }) export class AppModule {} and then in you component you can inject this service as following constructor ( private localStorageService: LocalStorageService ) { } ngOnInit() { this.localStorageService.set(key, value); console.log(this.localStorageService.get(key)); } You dont have to parse or stringify anything. Hope this will help. AGAIN: I have not tested it this code is entirely based on angular-2-local-storage documentation.

My Code: import React, { Component } from 'react' import { AppRegistry, StyleSheet, Text, Button, ScrollView, Dimensions, PanResponder, Animated, View } from 'react-native' import { StackNavigator } from 'react-navigation' export default class Home extends Component{ componentWillMount(){ this.animatedValue = new Animated.ValueXY(); this.panResponder = PanResponder.create({ onStartShouldSetPanResponder: (evt, gestureState) => true, onMoveShouldSetPanResponder: (evt, gestureState) => true, onPanResponderGrant: (e, gestureState) => { }, onPanResponderMove:Animated.event([ null,{dx: this.animatedValue.x , dy:this.animatedValue.y} ]), onPanResponderRelease: (e, gestureState) => { }, }) } render(){ const animatedStyle = { transform:this.animatedValue.getTranslateTransform() } return( <View style={styles.container}> <Animated.View style={[styles.box ,animatedStyle]} {...this.panResponder.panHandlers}> <Text>Home</Text> </Animated.View> </View> ) } } var styles = StyleSheet.create({ container: { flex: 1, marginLeft: 10, marginRight: 10, alignItems: 'stretch', justifyContent: 'center', }, box:{ height:90, width:90, textAlign:'center' } }); A: In my case I got this error because I forgot to change the View into Animated.View. A: Try this out. This will solve your issue. You need to initialize animatedValue in state object to make it work. constructor(props) { super(props); this.state = { animatedValue: new Animated.ValueXY() } } onPanResponderMove:Animated.event([ null,{dx: this.state.animatedValue.x , dy:this.state.animatedValue.y} ]),
