Hi I was facing this Issue when i was using Bootstrap 5 & angular12
<button class="btn btn-secondary dropdown-toggle" data-bs-toggle="dropdown" type="button" id="dropdownMenuButton" aria-haspopup="true" aria-expanded="false">Dropdown button
</button>
**And in angular.js**
"scripts": [
"./node_modules/jquery/dist/jquery.min.js",
"./node_modules/@popperjs/core/dist/umd/popper.min.js",
"./node_modules/bootstrap/dist/js/bootstrap.bundle.min.js"

The kernel I have used is the as a Laplacian kernel, which is commonly used for sharpening images. It enhances the edges and details in the image.
Secondly in the code for the TwoD_convolution I have made the following modifications:
1. I have tried normalizing the kernel, ensuring that the overall intensity of the image remains relatively stable across different regions.
2. I have clipped the values ensuring that no overflow occurs, thus minimizing artifacts like green dots.
I have run this on google colab and it works
```
import numpy as np
from PIL import Image
import matplotlib.pyplot as plt
import requests
def TwoD_convolution(img, kernel):
kernel = kernel[::-1]
for i in range(len(kernel)):
kernel[i] = kernel[i][::-1]
convolve = np.zeros((img.shape[0]+len(kernel)-1, img.shape[1]+len(kernel[0])-1, 3), np.uint8)
midx = len(kernel) // 2
midy = len(kernel[0]) // 2
# HERE I NORMALIZE THE KERNEL
kernel_sum = np.sum(kernel)
if kernel_sum == 0:
kernel_sum = 1
normalized_kernel = kernel / kernel_sum
for i in range(convolve.shape[0]):
for j in range(convolve.shape[1]):
for k in range(3):
cur = 0
for x in range(-midx, midx+1):
for y in range(-midy, midy+1):
if i+x >= 0 and i+x < img.shape[0] and j+y >= 0 and j+y < img.shape[1]:
cur += ((img[i+x][j+y][k]) * (normalized_kernel[midx+x][midy+y]))
convolve[i][j][k] = np.clip(cur, 0, 255) # RANGE CHECKING
return convolve
url = 'https://upload.wikimedia.org/wikipedia/en/7/7d/Lenna_%28test_image%29.png'
image = Image.open(requests.get(url, stream=True).raw)
img_array = np.array(image)
kernel = np.array([[0, -1, 0],
[-1, 5, -1],
[0, -1, 0]])
convolved_img = TwoD_convolution(img_array, kernel)
plt.figure(figsize=(10, 5))
plt.subplot(1, 2, 1)
plt.imshow(img_array)
plt.title('Original Image')
plt.axis('off')
plt.subplot(1, 2, 2)
plt.imshow(convolved_img)
plt.title('Convolved Image')
plt.axis('off')
plt.show()
```

Have a custom live search feature on our wordpress website, which only displays 20 products in the middle of the screen for any given search.
Would like to be able to remove this 20 limit, so that either 50 products, or unlimited products are shown.(Would like to try both options, to see which works best).
So far have come up with the code below for our function.php file, which unfortunately doesn't work:
function search_filter($query) {
if ( !is_admin() && $query->is_main_query() ) {
if ($query->is_wpsc_gc_live_search_pre_get_posts) {
$query->set('posts_per_page', -1);
}
}
}
add_action('pre_get_posts','search_filter');`
Code below from the live search file that may help with the tweaking of the above code:
function wpsc_gc_start_search_query() {
global $wp_query, $wpsc_query;
$product_page_id = wpsc_get_the_post_id_by_shortcode('[productspage]');
$post = get_post( $product_page_id );
$wp_query = new WP_Query( array( 'pagename' => $post->post_name ) );
add_action( 'pre_get_posts', 'wpsc_gc_live_search_pre_get_posts' );
wpsc_start_the_query();
remove_action( 'pre_get_posts', 'wpsc_gc_live_search_pre_get_posts' );
list( $wp_query, $wpsc_query ) = array( $wpsc_query, $wp_query ); // swap the wpsc_query object
$GLOBALS['nzshpcrt_activateshpcrt'] = true;
What we are basically trying to do is set the following:
Number of products per page to show during the live search, at either 50, or unlimited (would like to try both scenarios).
Code below, which relates to the number of products showing per page:
wpsc_products_per_page
Would be great for some help and advise on how we can getting the above filter to work.
Created the above filter for our themes function.php file, which needs tweaking. |

I am observing a strange behaviour where GCC (but not clang) will skip a pointer-reset-after-free expression in the global destruction phase and with certain values of `-O?`. I can reproduce this with every version I tried (7.2.0, 9.4.0, 12.3.0 and 13.2.0) and I'm trying to understand if this is a bug or not.
The phenomenon occurs in the [C++ wrapper for lmdb][1]; here are the functions that are involved directly:
static inline void
lmdb::env_close(MDB_env* const env) noexcept {
delete ::mdb_env_close(env);
}
class lmdb::env {
protected:
MDB_env* _handle{nullptr};
public:
~env() noexcept {
try { close(); } catch (...) {}
}
MDB_env* handle() const noexcept {
return _handle;
}
void close() noexcept {
if (handle()) {
lmdb::env_close(handle());
_handle = nullptr;
// std::cerr << " handle now " << handle();
}
// std::cerr << "\n";
}
I use this wrapper in a class `LMDBHook` of which I create a single, static global variable:
class LMDBHook
{
public:
~LMDBHook()
{
if (s_envExists) {
s_lmdbEnv.close();
s_envExists = false;
delete[] s_lz4CompState;
}
}
static bool init()
{
if (!s_envExists) {
try {
s_lmdbEnv = lmdb::env::create();
//snip
} catch (const lmdb::error &e) {
// as per the documentation: the environment must be closed even if creation failed!
s_lmdbEnv.close();
}
}
return false;
}
//snip
static lmdb::env s_lmdbEnv;
static bool s_envExists;
static char* s_lz4CompState;
static size_t s_mapSize;
};
static LMDBHook LMDB;
lmdb::env LMDBHook::s_lmdbEnv{nullptr};
bool LMDBHook::s_envExists = false;
char *LMDBHook::s_lz4CompState = nullptr;
// set the initial map size to 64Mb
size_t LMDBHook::s_mapSize = 1024UL * 1024UL * 64UL;
I first came across this issue because an application using `LMDBHook` would crash just before exit when built with GCC but not with clang, and initially thought that this was some subtle compiler influence on the order of calling dtors in the global destruction phase. Indeed, allocating `LMDH` *after* initialising the static member variables will not trigger the issue.
But the underlying issue here is that the line `_handle = nullptr;` from `lmdb::env::close()` will be skipped by GCC in the global destruction phase (but not when called e.g. just after `lmdb::env::create()` in `LMDBHook::init()`) and "only" when compiled with -O1, -O2 -O3 or -Ofast (so not with -O0, -Og, -Os or -Oz).
The 2 trace output exprs in `lmdb::env::close()` are mine; if I outcomment them the reset instruction is not skipped.
The fact that it only happens under specific circumstances during global destruction makes me think it is maybe not a bug though if so the behaviour should not depend on the optimisation level.
I have made a self-contained/standalone demonstrator that contains the `lmdb++` headerfile extended with trace output exprs and where the create and close functions simply allocate the `MDB_env` structure with `new` and `delete`, plus the `lmdb` headerfile with an added definition of the `MDB_env` structure (normally it's opaque) : https://github.com/RJVB/gcc_potential_optimiser_bug.git . The README has instructions how to use the Makefile but it should be pretty self-explanatory.
Here's some example output:

EDIT: The above examples are with self-built compilers on Linux but the system compilers show the same behaviour, also on Mac, and the choice of C++ runtime (libc++ or libstdc++) has no influence on either platform.
EDIT2: the demonstrator also has an alternative implementation of `lmdb::env::close()` as I would have written it, which caches the `_handle` ptr in a tmp. variable, resets `_handle` and only then frees the cached pointer. This implementation is not subject to whatever this issue really is.

I have written a code for finding prime numbers using sieve of Eratosthenes algorithm, but the problem is my code works as it tends to be, but for only some numbers. It shows like "entering upto-value infinitely" as the error and for some numbers it works perfectly. As I started recently studying C in-depth I couldn't find what is going wrong. I request the code-ies to help me in this case, and also help me realize what is the mistake, why it happens and how to prevent it.
Here's the code:
```
#include <stdio.h>
int main()
{
int n;
printf("enter number: ");
scanf("%d",&n);
int arr[n],i,pr=2;
for(i=0;pr<=n;i++)
{
arr[i]=pr;
pr++;
}
int j,k;
while(arr[k]<=n)
{
for(j=2;j<n;j++)
{
for(k=0;k<n;k++)
{
if(arr[k]%j==0 && arr[k]>j)
arr[k]=0;
}
}
}
for(i=0;arr[i]<=n;i++)
{
if(arr[i]!=0)
printf(" %d",arr[i]);
}
printf("\n");
return 0;
}

I work with the Spring framework and I encounter problem with mapping set of roles from many-to-many table. Let me show you my classes.
```
public class Role {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
@NonNull
private String authority;
@ManyToMany(mappedBy = "roles", fetch = FetchType.EAGER/*, cascade=CascadeType.MERGE*/)
private Set<AppUser> appUsers;
public Role(@NonNull String authority) {
this.authority = authority;
}
public Role() {
}
}
```
```
public class AppUser implements Serializable {
@Serial
private static final long serialVersionUID = -8357820005040969853L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
// @NonNull
@Column(unique = true)
private /*final*/ String username;
// @NonNull
private /*final*/ String password;
@ManyToMany(fetch = FetchType.EAGER/*, cascade=CascadeType.MERGE*/)
// @NonNull
@JoinTable(name = "users_roles",
joinColumns = @JoinColumn(name = "role_id"/*, referencedColumnName = "id"*/),
inverseJoinColumns = @JoinColumn(name = "user_id"/*, referencedColumnName = "id"*/))
private Set<Role> roles;
}
```
Here is the saving process:
```
@Bean
// @Transactional
public CommandLineRunner run(RoleRepository roleRepository, UserRepository userRepository, PasswordEncoder passwordEncoder) {
return args -> {
if (roleRepository.findByAuthority("ADMIN").isEmpty()) {
Role admin = roleRepository.save(new Role("ADMIN"));
Role user = roleRepository.save(new Role("USER"));
userRepository.save(new AppUser("admin", passwordEncoder.encode("admin"), new HashSet<>() {
{
add(admin);
add(user);
}
}));
}
};
}
```
And here is the moment when I want to retrieve roles for the user:
```
@Component
public class UserInterceptor implements HandlerInterceptor {
private final UserRepository userRepository;
private final RoleRepository roleRepository;
public UserInterceptor(UserRepository userRepository, RoleRepository roleRepository) {
this.userRepository = userRepository;
this.roleRepository = roleRepository;
}
@Override
public void postHandle(@NonNull HttpServletRequest request,
@NonNull HttpServletResponse response,
@NonNull Object handler,
ModelAndView modelAndView) {
if (modelAndView != null) {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
Optional<AppUser> appUser = userRepository.findByUsername(authentication.getName());
if (appUser.isPresent()) {
Set<Role> set = roleRepository.findByAppUsers(new HashSet<>() {
{
add(appUser.get());
}
});
log.info("Roles for user {}: {}", appUser.get().getUsername(), appUser.get().getRoles());
modelAndView.addObject("username", appUser.get().getUsername());
modelAndView.addObject("roles", appUser.get().getRoles());
} else
modelAndView.addObject("username", "anonymous");
}
}
}
```
The most interesting part is that when I login into system as the "admin" with the password "admin", it sees my User in the database and I actually have value inside Optional<AppUser> appUser. After checking presence I create simple set just to check, whether it maps roles for particular users and it does, after that I have set of roles retrieved by User object.
And now comes the magic part: if I try to get roles from the user doing appUser.get().getRoles(), I get EMPTY SET OF ROLES IN THE appUser OBJECT. I mean, I could have tried to get all roles using an extra set created by userRepository.findByUsername, but I feel like it shouldn't work this way. Can anyone help me please, I would appreciate it and it would help me to get Spring framework. Thanks in advance.
P.S. Here is the table from the database and yes, names of columns are messed up, I've fixed it already.

To build a subset of a third-party C++ library like XLA as a static library with headers using Bazel, you need to properly define your BUILD file and ensure that the necessary targets are included. also,
Regarding the absence of the .a or .lo file in your bazel-bin directory, it's possible that Bazel is not actually building the library because it's empty due to having no source files. Since you mentioned you want to compile a dynamic library with some wrapper code, you'll need to add some source files to your my_xla target, even if they're just empty placeholder files.
cc_library(
name = "my_xla",
hdrs = glob(["path/to/xla/client/*.h"]), ### Adjust the path
srcs = ["path/to/emptyfile.cc"], ### Replace Placeholder source file
deps = [
"@xla//xla/client:xla_builder",
"@com_google_absl//absl/strings:str_format",
"@tsl//tsl/platform:logging",
"@tsl//tsl/platform:platform_port",

i am using java big decimal. but still i am not getting expected result..
public class DecimalAdjustEx {
public static void main(String[] args) {
BigDecimal v1 = new BigDecimal("100");
BigDecimal v2 = new BigDecimal("75");
BigDecimal reminder = BigDecimalUtils.divide(v1,v2);
System.out.println("reminder= "+reminder);
BigDecimal v1Result = BigDecimalUtils.multiply(reminder,v2);
System.out.println("v1 Result= "+v1Result);
}
}
Utils class:
public class BigDecimalUtils {
public static final MathContext DEFAULT_MATH_CONTEXT = new MathContext(34, RoundingMode.HALF_UP);
public static BigDecimal multiply(BigDecimal value1, BigDecimal value2) {
return value1.multiply(value2,DEFAULT_MATH_CONTEXT);
}
public static BigDecimal divide(BigDecimal value1, BigDecimal value2) {
return value1.divide(value2,DEFAULT_MATH_CONTEXT);
}
public static BigDecimal add(BigDecimal value1, BigDecimal value2) {
return value1.add(value2,DEFAULT_MATH_CONTEXT);
}
public static BigDecimal subtract(BigDecimal value1, BigDecimal value2) {
return value1.subtract(value2,DEFAULT_MATH_CONTEXT);
}
}
output:

v1 Result= 99.99999999999999999999999999999998
here v1 Result should be 100 right.
but why it is giving wrong one. how to handle these problems.
i cannot use more than 34 digits precision. and i do not want rounding. please suggest a solution..
consider i have huge application, no of arthimatic calculations going on. please suggest a feasible solution.

It depends what you understand as "typical medium enterprise"
AWS offers their own MongoDB, they name it DocumentDB and it is compatible to MongoDB. However, AWS DocumentDB does not provide the full set of features as MongoDB does.
MongoDB Enterprise has two license models. The first model is based on the amount of total amount of RAM you have installed at your MongoDB the data bearing nodes (i.e. `mongos` roters, config server and arbiter node do not cost anything)
The second model I don't remember anymore, either it was based on the amount of data or number of hosts.

The answer in the following link explains it better than I ever could. The answer goes into all the different date/time classes in Java, as well as their relation to sql types.
https://stackoverflow.com/questions/32437550/whats-the-difference-between-instant-and-localdatetime/32443004#32443004
A short summary:
The classes Instant and ZonedDateTime (as well as OffsetDateTime)
represent the same thing: a moment in time. The difference is that
ZonedDateTime and OffsetDateTime offer extra context and functionality
about timezones or time offsets, whereas Instant has no timezone or
offset specified. This can lead to differences especially when Daylight Saving Time is involved. For instance, take the following snippet of code:
ZonedDateTime z1 = ZonedDateTime.of(LocalDateTime.of(2019, 10, 26, 6, 0, 0), ZoneId.of("Europe/Amsterdam"));
Instant i1 = z1.plus(1, ChronoUnit.DAYS).toInstant();
Instant i2 = z1.toInstant().plus(1, ChronoUnit.DAYS);
System.out.println(i1);
System.out.println(i2);
The result will be this:
2019-10-27T05:00:00Z
2019-10-27T04:00:00Z
The difference stems from the fact that in the Amsterdam timezone, the 27th of October has an extra hour. When we convert to Instant the timezone information is lost, so adding a day will add only 24 hours.
LocalDateTime is a different beast alltogether. It represents a date
and time without timezone information. It does *not* represent a
moment in Time. It is useful for writing things such as "Christmas
morning starts at december 25th 00:00:00". This is true regardless of
timezone, and as such a ZonedDateTime or Instant would not be appropriate.

You can approach this by pivoting the dataset to a long format, then summing the rows where the party matches the population, and then pivoting back to wide.
```
library(tidyverse)
df |>
mutate(country=row_number())|>
pivot_longer(cols=-c(PartyA, PartyB, country),names_pattern = "(.*)Pop") |>
group_by(country) |>
mutate(PartyRel=sum(value[name==PartyA|name==PartyB])) |>
pivot_wider(id_cols = c(PartyA, PartyB,country,PartyRel))
# A tibble: 5 × 9
# Groups: country [5]
PartyA PartyB country PartyRel Christian Muslim Jewish Sikh Buddhist
<chr> <chr> <int> <dbl> <dbl> <dbl> <dbl> <dbl> <dbl>
1 Christian Jewish 1 21 12 71 9 0 1
2 Muslim Muslim 2 93 1 93 2 0 0
3 Muslim Christian 3 79 74 5 12 1 2
4 Jewish Muslim 4 86 14 86 0 0 0
5 Sikh Buddhist 5 55 17 13 4 10 45
```
To understand what is happening here have a look at the result after the pivot_longer():
```
# A tibble: 25 × 5
PartyA PartyB country name value
<chr> <chr> <int> <chr> <dbl>
1 Christian Jewish 1 Christian 12
2 Christian Jewish 1 Muslim 71
3 Christian Jewish 1 Jewish 9
4 Christian Jewish 1 Sikh 0
5 Christian Jewish 1 Buddhist 1
6 Muslim Muslim 2 Christian 1
7 Muslim Muslim 2 Muslim 93
8 Muslim Muslim 2 Jewish 2
9 Muslim Muslim 2 Sikh 0
10 Muslim Muslim 2 Buddhist 0
# ℹ 15 more rows
# ℹ Use `print(n = ...)` to see more rows
```
then it's just a case of identifying the correct rows to sum. I think this is neater than a rowwise calculation. |

I am trying to make a CountDownTimer for my Android app, but every time I try to start it using just `timer.start()`, it starts multiple timers. I don't know why.
My code for this is:
```
val timer = object: CountDownTimer(5000, 1000) {
override fun onTick(millisUntilFinished: Long) {
println(millisUntilFinished)
if (new == null) {
skipTimeButton.visibility = View.GONE
exoSkip.visibility = View.VISIBLE
dissappeared = false
return
}
}
override fun onFinish() {
val skip = currentTimeStamp
skipTimeButton.visibility = View.GONE
exoSkip.visibility = View.VISIBLE
disappeared = true
}
}
timer.start()
``` |
Your fairly "verbose" code can be written a lot shorter if you leave out all the repetitions:
<!-- begin snippet:js console:true -->
<!-- language:lang-html -->
A<button id="na">1</button>
B<button id="nb">1</button>
X<button id="nx">1</button>
Y<button id="ny">1</button>
Z<button id="nz">1</button>
<div id="highest"></div>
<!-- language:lang-js -->
const btns=[...document.querySelectorAll("button")],
highest=document.getElementById("highest");
btns.forEach(b=>b.onclick=()=>{
b.textContent=+b.textContent+1;
highest.textContent="The most popular button ID is "+btns.reduce((a,c)=>(+c.textContent>+a.textContent?c:a)).id
});
setInterval(()=>btns[Math.floor(btns.length*Math.random())].click(), 1000);
<!-- end snippet -->
The above snippet does not use local storage as this is not supported on Stackoverflow. If you require this feature, then the local storage command should be included within the `onclick` function definition.
Maybe the expression
```
btns.reduce((a,c)=>(+c.textContent>+a.textContent?c:a)).id
```
deserves a short explanation: it uses the `Array.reduce()` method that loops over all elements of the `btns` array and compares each element's `.textContent` attribute value with the one in the accumulator variable `a`. Tha `a` variable is initially set to the first element of the `btns` array and is assigned the result of the ternary operator expression `(+c.textContent>+a.textContent?c:a)`. So, if the current element's (`c`) value is higher than the one stored in `a` it will be assigned to `a`. At the end of the `.reduce()` loop the element stored in `a` is returned and its attribute `.id` is then used for the outer expression stating the most popular id. |
I think if you just explicitly capture both `chatForView` and `chatUser`, it should work:
```
.fullScreenCover(isPresented: $shouldNavigateToChatView) { [chatUser, charForView] in
if let user = chatUser {
ChatView(oppUser: user)
} else if let chat = chatForView {
ChatView(chat: chat)
} else {
ProgressView()
}
}
```
That said, this is a use case for `fullscreenCover(item:)`, assuming `ChatModel` and `User` are `Identifiable`. This overload presents the full screen cover when `item` is not nil.
```
.fullScreenCover(item: $chatUser) { user in
ChatView(oppUser: user)
}
.fullScreenCover(item: $chatForView) { chat in
ChatView(chat: chat)
}
```
Now you don't need `shouldNavigateToChatView`.
Other notes:
`viewModel` should be `@StateObject`:
```
@StateObject private var viewModel = ChatListViewModel()
```
When setting `chatForView` or `chatUser`, remember to set the other one to `nil`, e.g.
```
chatForView = chat
chatUser = nil // also do this
```
<hr>
If there is a case where `chatForView`/`chatUser` are received later, but you want to show the full screen cover first, it'd better to model the three situations with an enum:
```
enum ChatInfo: Hashable, Identifiable {
case chat(ChatModel)
case user(User)
case loading(SomeInfo)
var id: ChatInfo { self }
}
...
@State chatInfo: ChatInfo?
...
.fullScreenCover(item: $chatInfo) { info in
// ChatView will decide what to do in each case
// e.g. in the case of .loading, display a progress
// indicator and use SomeInfo to fetch things.
ChatView(info)
}

I am trying to connect below spark connectors from Databricks to Snowflake.On the snowflake side i can access the account using "Login via AzureAD" which is my own azure account credentials.
But while trying to provide the same in spark connectors for snowflake is not working.
options = {
"sfUrl": url,
"sfUser": my azure username,
"sfPassword": corresponding pwd,
"sfDatabase": db,
"sfSchema": schema,
"sfWarehouse": warehouse,
"Role":role
}
Please note if i have login using service account details created in snowflake side then that is working.
Any pointer how to connect to snowflake using own credentials from databricks? |

You could rewrite `(?<=^| )` as `(?:\s|^)` and keep that match in the replacement instead of using `\K` which is not supported in JavaScript.
You could write the pattern as:
((?:\s|^)([a-z])\2+)(?=\s|$)|([a-z])(?=\3)
The pattern matches:
- `(` Capture **group 1**
- `(?:\s|^)` Match either a whitespace char or assert the start of the string
- `([a-z])\2+` Capture a single char a-z in **group 2** and repeat matching that same char 1 or more times
- `)` Close group 1
- `(?=\s|$)` Positive lookahead, assert either a whitespace char or the end of the string to the right
- `|` Or
- `([a-z])(?=\3)` Capture a single char a-z in **group 3** while asserting the same character directly to the right

In the realm of computer programming and system administration, efficiency and precision are paramount. Command-line interfaces (CLIs) have long been the go-to tool for professionals seeking to interact with computers at a granular level. At the heart of many CLI operations lie command-line arguments, powerful tools that enable users to tailor program behavior, configure settings, and execute complex tasks with ease. In this comprehensive guide, we will delve deep into the world of command-line arguments, exploring their nuances, syntax, and practical applications.
https://stackoverflow.comhttps://stackoverflow.com/questions/ask#Types of Command-Line Arguments:
Flags or Options:
Flags or options modify the behavior of a program by enabling or disabling certain features or settings. They are preceded by a hyphen (-) or double hyphen (–), followed by a keyword or abbreviation representing the option. For example:
$ ls -l $ git commit -m “Initial commit”
Positional Arguments:
Positional arguments are parameters provided to a program based on their position in the command-line invocation. They are not preceded by flags or options and are instead interpreted based on their order. For example:...........

Fixed it. It works if I create the ```.gitignore``` using Windows Subsystem for Linux (Ubuntu). It does not work if created through Windows 10 VS Code editor. A similar thing is also mentioned in this [solution][1]. It also worked when I created the ```.gitignore``` file using echo in Git Bash which is a Linux environment. Strange indeed! It probably has something to do with the carriage return (CR) and line feed (LF).

I am trying to simulate a web site access via C# code. The flow is
1) HTTP Get the the login Page. This succeeds.
2) HTTP Post to login page. This returns status 302, I disabled auto redirect in HttpClientHandler. Validated the cookie returned, it has the login cookie.
3) HTTP Get the actual content page. Returns success code 200, but the content is always trimmed. This is the same page to which step 2 re-directs.
I have tried by even letting the auto-redirect enabled in the HttpClientHandler. Even then the response is trimmed.
In postman, when I directly do step 2 allowing re-direct. The content comes properly.
This used to work sometime back on the website. It's PHP based website and it's protected by CloudFare. Not sure if the cloudfare is recent thing.
I checked the headers sent via the browser for the same and replicated the same in the code but still it doesn't seems to work.

But this response is truncated. I have enabled automatic de-compression of the data.
Any idea what might be missing.
Interestingly, when posting to login page via Postman without explicitly adding any other header, the login process works and retrieves the re-directed page.

I have two dataframes.
df1
col1 var1 var2 var3
X11 NA (for var3)
X12 NA (for var2)
X13 NA (for var1)
df1 has a few columns (float64 type representing some categories) like var1, var2, var3 with values between 1-5 for each and some missing values for the categories.
I want to fill in the missing values (in each of var1, var2, and var3 columns) using another dataframe, df2 such that df2 has a column with the value for the category.
df2
col1 col2 val col4
X11 var1 3 X11-X21
X12 var3 2 X21-X22
X13 var2 1 X13-X32
col4 is the concatenation of col1 and col2 but it did not help much.
How could I do this?
Since we need to look up on several columns and also because of the structure of df1, I found it complicated to use pivot or melt or even one-hot encoding (produces 5 columns each with _1 to _5 suffixed.
I also though about creating a set but then the pairs must be unique which is not the case.
Same when I thought of using dictionary as I cannot think of unique keys.
How could I solve this issue?
Thanks. |

Is the following of any help? The basic paradigm is to put your read sockets to a list, then do a select and then check which socket has data available and then act on the data.
#!/usr/bin/python3
import time
import socket
import select
import threading
glob_control_read_socket = socket.socket(family=socket.AF_INET, type=socket.SOCK_DGRAM)
glob_control_read_socket.bind(('localhost', 0))
glob_control_write_socket = socket.socket(family=socket.AF_INET, type=socket.SOCK_DGRAM)
glob_control_write_socket.connect(('localhost', glob_control_read_socket.getsockname()[1]))
glob_server_read_socket = socket.socket(family=socket.AF_INET, type=socket.SOCK_DGRAM)
glob_server_read_socket.bind(('localhost', 12000))
print("Server running on port " + str(glob_server_read_socket.getsockname()[1]))
def sockets_shutdown():
glob_control_write_socket.close()
glob_control_read_socket.close()
glob_server_read_socket.close()
print("Graceful shutdown")
def handle_server_read():
read_str = glob_server_read_socket.recv(100).decode("utf-8")
print("Server got: " + read_str.rstrip())
def sockets_thread_main():
read_sockets_list = [glob_control_read_socket, glob_server_read_socket]
while True:
try:
read_sockets,_,_ = select.select(read_sockets_list, [], [])
for ready_socket in read_sockets:
if ready_socket == glob_control_read_socket:
control_bytes = glob_control_read_socket.recv(32)
if control_bytes == b"QUIT":
sockets_shutdown()
return
if ready_socket == glob_server_read_socket:
handle_server_read()
except Exception as e:
print(str(e))
sockets_thread = threading.Thread(target = sockets_thread_main, args = ())
try:
sockets_thread.start()
while True:
time.sleep(100000) # Placeholder, do something real here
except KeyboardInterrupt:
glob_control_write_socket.send(b"QUIT")
sockets_thread.join()

Based on the answer given by phd, I decided to tweak it a bit and write a script that automatically fixes the tab width based on pressing `2<Tab>` for going from 2 to 4 tabs, as well as being able to fix intermingled tab/4-space indentation by pressing `4<Tab`. It makes use of a global variable to prevent the command from running multiple times, but otherwise simply executes the commands given in phd's answer. Pressing a number key and then Tab in normal mode will cause the indentation to be changed from that number to your default tabstop setting.
let g:retab_done = 0
function Retab()
if !v:count || g:retab_done
return
endif
let g:retab_done = 1
let current_width = &tabstop
execute "set noexpandtab tabstop=" . v:count
retab!
execute "set expandtab tabstop=" . current_width
retab
return
endfunction
nmap <Tab> :call Retab()<CR> |
Here is a regex that will match any phone number for every country in the world regardless of the number of digits. It matches formatted and unformatted national and international phone numbers.
```js
// This will match any phone number in a file
const pattern = /(\+)?(\(?\d+\)?)(([\s-]+)?(\d+)){0,}/g
// If you want to match phone numbers line by line consider
// adding '^' at beginning of regex and '$' at end of it
// like below
const pattern = /^(\+)?(\(?\d+\)?)(([\s-]+)?(\d+)){0,}$/g
```
If you want to adjust it to match a certain number of digits,
you can do that easily.

I suspect the reason is that you've defined the 'status' field as text in the index's schema. The text type is used for free-text searches, and as such has the notion of "stop words" - common words that are ignored - and "on" is probably there.
You should use a tag field instead. |
I was trying to run my assembly language program and it is when i try to enter the 2nd input, the cursor freezes and the DOSbox emulator would crash after a few seconds of delay.
I've tried running other assembly language programs and they seem to be working fine. Im not sure of the reason behind this, could it be an error in my code (MASM format) / not enough RAM to run the program? My code is attached below and I had 1.5GB of RAM available while I was running the program.

I am trying to do a transparent background for my MatDialog component. Here is the code:
*parent.component.html*
openDialog(){
const dialogConfig = new MatDialogConfig();
dialogConfig.width = '340px';
dialogConfig.height = '476px';
dialogConfig.autoFocus = false;
dialogConfig.panelClass = "dialogClass";
dialogConfig.data = this.item;
this.dialog.open(ChildComponent, dialogConfig)
}
*styles.css (global file, not the parent component one)*
.dialogClass{
background-color: pink; //pink to see if it works
}
*(changes background for this particular dialog)*
**OR**
mat-dialog-container {
background-color: pink;
}
*(changes background for all dialogs)*
This code works (I can see pink for a second every time I open the dialog), but it gets instantly covered with a white layer. All I have in my ChildComponent is displayed *over* this layer:
**MatDialog background -> White layer -> ChildComponent**
If ChildComponent *.css* and *.html* files are empty, it still appears.
Setting a block with transparent background doesn't help either.
How do I delete this white layer from a dialog?

First make sure you are using the latest version of UMP SDK inside your dependencies and don't rely on the version embedded with `play-services-ads`, that version could be outdated.
```gradle
dependencies {
implementation("com.google.android.gms:play-services-ads:22.6.0")
implementation("com.google.android.ump:user-messaging-platform:2.2.0")
}
```
Second, in my case Android [DataStore][1] was causing preferences reset. The same preferences file is used to store consent from UMP SDK, coincidently they had the same name. It seems that DataStore tries to migrate all preferences when it finds the preferences file, and then deletes it, which causes UMP SDK to lose stored consent info.
```kotlin
companion object {
private const val PREFS_FILE_NAME = "user_prefs"
private val Context.dataStore by preferencesDataStore(
name = PREFS_FILE_NAME,
produceMigrations = {
listOf(SharedPreferencesMigration(it, it.packageName + "_preferences"))
})
}
```
UMP SDK uses `my.package.name_preferences.xml` file by default (can't change it) to store consent info. My old preferences also were stored in the same file, and when I switched to DataStore I had to make a migration from that file.
To resolve the issue, I simply removed the migration since it is not that important for me.

I could do it with possible hack, i don't know its right solution but it works.
I took 4 different radio buttons and HBox
widgets.HBox([radio1,radio2,radio3,radio4])
Then after selecting one radio button i m de-selecting the other radio button which is selected.
Here how i done :
import ipywidgets as widgets
output_radio_selected = widgets.Text()
radio1 = widgets.RadioButtons(options=['Option 1'])
radio2 = widgets.RadioButtons(options=['Option 2'])
radio3 = widgets.RadioButtons(options=['Option 3'])
radio4 = widgets.RadioButtons(options=['Option 4'])
radio1.index = None
radio2.index = None
radio3.index = None
radio4.index = None
def radio1_observer(sender):
#print(sender)
radio2.unobserve(radio2_observer, names=['value'])
radio2.index = None
radio3.unobserve(radio3_observer, names=['value'])
radio3.index = None
radio4.unobserve(radio4_observer, names=['value'])
radio4.index = None
global selected_option
output_radio_selected.value = radio1.value
selected_option = output_radio_selected.value
print('Selected option set to: ' + selected_option)
radio2.observe(radio2_observer, names=['value'])
radio3.observe(radio3_observer, names=['value'])
radio4.observe(radio4_observer, names=['value'])
def radio2_observer(sender):

radio1.index = None
radio3.unobserve(radio3_observer, names=['value'])
radio3.index = None
radio4.unobserve(radio4_observer, names=['value'])
radio4.index = None
global selected_option2
output_radio_selected.value = radio2.value
selected_option2 = output_radio_selected.value
print('Selected option set to: ' + selected_option2)
radio1.observe(radio1_observer, names=['value'])
radio3.observe(radio3_observer, names=['value'])
radio4.observe(radio4_observer, names=['value'])
def radio3_observer(sender):

radio2.index = None
radio4.unobserve(radio4_observer, names=['value'])
radio4.index = None
global selected_option3
output_radio_selected.value = radio3.value
selected_option3 = output_radio_selected.value
print('Selected option set to: ' + selected_option3)
radio1.observe(radio1_observer, names=['value'])
radio2.observe(radio2_observer, names=['value'])
radio4.observe(radio4_observer, names=['value'])
def radio4_observer(sender):

According to the [docs][1], to be on the safe side you should append the absolute path of the image or directory you want to serve.
app.use('/uploads', express.static(__dirname + '/uploads'))

I am trying to make a CountDownTimer for my Android app, but every time I try to start it using just `timer.start()`, it starts multiple timers. I don't know why.
My code for this is:
```
fun DissapearSkip(){
skipTimeButton.visibility = View.VISIBLE
exoSkip.visibility = View.GONE
skipTimeText.text = new.skipType.getType()
skipTimeButton.setOnClickListener {
exoPlayer.seekTo((new.interval.endTime * 1000).toLong())
}
val timer = object: CountDownTimer(5000, 1000) {
override fun onTick(millisUntilFinished: Long) {
println(millisUntilFinished)
if (new == null) {
skipTimeButton.visibility = View.GONE
exoSkip.visibility = View.VISIBLE
dissappeared = false
return
}
}
override fun onFinish() {
val skip = currentTimeStamp
skipTimeButton.visibility = View.GONE
exoSkip.visibility = View.VISIBLE
dissappeared = true
}
}
timer.start()
}
```
also the new variable is for getting the timestamp type and info |
I'm new at ReactJs and trying to learn ContextAPI but I'm having this error. I read titles about this situation but I can't reach to solution. Firstly I tried to re-install react as a old version but it didn't changed. I tried to wrap App inside of app.js instead of index.js but I had same result as it happens right now.
>*App.js*
import React, { Component } from 'react'
import './App.css';

}
export default App;

I'm currently developing my first project, a simple paint application using Java Swing and AWT. While implementing the painting functionality, I encountered an issue with accurately capturing mouse movements, especially when moving the mouse quickly.
I've designed the application to update the drawing coordinates in response to mouse events (mouseDragged and mouseMoved methods in the PaintPanel class), triggering repaints to render the drawings. However, despite my efforts, I've noticed that fast mouse movements sometimes result in skipped points, leading to gaps in the drawn lines.
Here's my PaintPanel class, which manages the painting functionality:
```
public class PaintPanel extends JPanel implements MouseMotionListener{
public Point mouseCoordinates;
boolean painting = false;
public PaintPanel() {
this.setPreferredSize(new Dimension(1000,550));
this.setBackground(Color.white);
this.addMouseMotionListener(this);
}
public void paintComponent(Graphics g) {
Graphics2D g2D = (Graphics2D) g;
g2D.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
if(painting == false) {
super.paintComponent(g2D);
}
if(mouseCoordinates != null) {
g2D.setColor(UtilePanel.col);
g2D.fillOval((int)mouseCoordinates.getX(),(int)mouseCoordinates.getY(),UtilePanel.brushSize, UtilePanel.brushSize);
this.setCursor( this.getToolkit().createCustomCursor(
new BufferedImage( 1, 1, BufferedImage.TYPE_INT_ARGB ),
new Point(),
null ) );
}
}
@Override
public void mouseDragged(MouseEvent e) {
mouseCoordinates = e.getPoint();
painting = true;
repaint();
}
@Override
public void mouseMoved(MouseEvent e) {
mouseCoordinates = e.getPoint();
repaint();
}
}
```
Here's the UtilePanel class if it help :
```
public class UtilePanel extends JPanel {
static Color col=Color.black;
static int brushSize = 5;
public UtilePanel(){
this.setPreferredSize(new Dimension (1000,150));

```
Additionally, I attempted to incorporate a game loop to continuously poll for mouse input, hoping it would improve the accuracy of mouse movement capturing. However, even with the game loop in place, the problem persists.
I'm unsure if my approach to painting by omitting super.paintComponent(g) in paintComponent is the correct way or there's a better way to do it.
Could someone provide insights or suggestions on how to improve the mouse event capturing to guarantee precise rendering, especially during rapid mouse movements?
Your assistance would be greatly appreciated. Thank you!

I am trying to simulate a web site access via C# code. The flow is
1) HTTP Get the the login Page. This succeeds.
2) HTTP Post to login page. This returns status 302, I disabled auto redirect in HttpClientHandler. Validated the cookie returned, it has the login cookie.
3) HTTP Get the actual content page. Returns success code 200, but the content is always trimmed. This is the same page to which step 2 re-directs.
I have tried by even letting the auto-redirect enabled in the HttpClientHandler. Even then the response is trimmed.
In postman, when I directly do step 2 allowing re-direct. The content comes properly.
This used to work sometime back on the website. It's PHP based website and it's protected by CloudFare. Not sure if the cloudfare is recent thing.
I checked the headers sent via the browser for the same and replicated the same in the code but still it doesn't seems to work.

I followed Herb Sutter's [NVI idiom][1] on my class design because of its benefits. My abstract class is as follows in short.
class Communicator {
public:
bool Connect(void) {
// some preoperations
return DoConnect();
}
// 3 more similar public member functions
private:
virtual bool DoConnect(void) = 0
// 3 more similar pure virtual member functions
}
I inject Communicator class to the class I want to test as follows (I found this method from [Google docs][2]) :
template <typename CommunicatorClass> // There will be some constraints
class TestingClass {
public:
TestingClass(std::unique_ptr<CommunicatorClass> comm) : comm_{std::move(comm)} { }
private:
std::unique_ptr<CommunicatorClass> comm_ = nullptr;
}
My Mock class :
class MockCommunicator : public Communicator {
public:
MOCK_METHOD(bool, Connect, ());
// 3 more mocks
}
My Test suite Setup:
// some code ..
auto mock = std::make_unique<MockCommunicator>();
TestingClass<MockCommunicator>(std::move(mock));
As you can guess since I did not override 4 private virtual functions MockCommunicator becomes abstract and the compiler gives error. Options I thought :
1) Overriding virtual functions in MockCommunicator. (It seems ugly, but I am closest to this approach)
2) I could convert pure virtual functions to virtual functions but I am not the only one who owns the code base. I want to force other developers to implement their own implementation.
3) Making MockCommunicator the friend of Communicator class and mock private virtual functions. ( I think this is absolutely wrong. Is it?)
4) Giving up on NVI because of its complexity to the code base
Is there any recommended way of handling this situation?
Note : I use C++20

You can send the token as part of the request body, headers, or query parameters using an HTTPS request.
const express = require('express');
const jwt = require('jsonwebtoken');
const app = express();
const jwtSecret = process.env.JWT_SECRET;
app.post('/fetchElement', (req, res) => {
const token = req.body.token; // Assuming token is sent in the request body
jwt.verify(token, jwtSecret, (err, decoded) => {
if (err) {
return res.status(401).json({ message: 'Unauthorized' });
}
const userId = decoded.user_id; // Extract user_id from decoded token
// Fetch the corresponding element using the user_id
// Example: Element.findOne({ userId: userId }, (err, element) => { ... });
// Respond with the fetched element
res.json({ element: fetchedElement });
});
});
app.listen(3000, () => console.log('Express server running'));
Ensure that both Laravel and Express.js applications have the same JWT secret to encode and decode tokens correctly.

I am discovering the concept of source generators.
In order to execute some logic with a source generator on some files (image files more precisely) based on the folders structure of the targeted/referencing project, I need to:
- Get the path/Directory of the targeted/referencing project.
### First approach
```
namespace SourceGen
{
[Generator]
public class Class1 : IIncrementalGenerator
{
public void Initialize(IncrementalGeneratorInitializationContext context)
{
var projDirectory = context.AnalyzerConfigOptionsProvider
.Select((x, _) => x.GlobalOptions
.TryGetValue("build_property.MSBuildProjectDirectory", out var projectDirectory) ? projectDirectory : null);
File.AppendAllText("\\" + "log.txt", projDirectory );
}
}
}
```
I am logging to a file for debugging purposes (to check the property value I am reading in this case) since I can't find another way to debug this kind of project.
In the log file I get, since `IncrementalValueProvider<string>.ToString()` returns the type and not whatever value is there:
> Microsoft.CodeAnalysis.IncrementalValueProvider`1[System.string].
### Second approach
following https://stackoverflow.com/a/66548212 :
```
var mainSyntaxTree = context.CompilationProvider.Select((x, _) => x.SyntaxTrees.First(x => x.HasCompilationUnitRoot));
var directory = Path.GetDirectoryName(mainSyntaxTree.Select((x, _) => x.FilePath);
```
The same issue `Path.GetDirectoryName()` is complaining that the provided parameter is of type `IncrementalValueProvider<string>` while expecting a `string`.
Not sure how can I get a useful string value (`FilePath`) out of the type `IncrementalValueProvider<string>`.
### Third approach
This time the log file was not written/created at all:
```
var provider = context.AnalyzerConfigOptionsProvider.Select((x, _) =>
{
x.GlobalOptions.TryGetValue("build_property.MSBuildProjectDirectory", out var projectDirectory);
File.AppendAllText("\\" + "log.txt", "testing" + projectDirectory);
return projectDirectory;
});
```
Docs: https://github.com/dotnet/roslyn/blob/main/docs/features/incremental-generators.cookbook.md |
Source generators get the referencing project path - retrieve useful value from IncrementalValueProvider<string> |

In addition to adding code, you can also add a module, user form, or class module. I think the reason for that is that VBA needs one of those four things to determine that a file is a macro-enabled workbook. My guess is that this was done to distinguish between files that contain macros (and therefore have to be enabled) and files that *can* contain macros but do not (e.g. xlsm, xlsb, etc. file with no macros.)
As would be expected, if you later remove the code or modules / userform later and there are no more in the file, Excel will remove your custom name. And the custom name reverts back to VBAProject |

In EF terms it seems like it could just be:
var d = db.Users
.OrderByDescending(u => u.Xp)
.AsEnumerable()
.Select((u, i) => new { Rank=i+1, User = u })
.ToDictionary(at => at.Rank, at=>at.User);
You list all your users out of the DB in order of XP, and you use the overload of `Select((user,index)=>...)` to assign the rank (the index + 1) and for convenience let's put them in a dictionary indexed by rank
Now you have a dictionary where, for any given user you can get the surrounding users by the rank of the user you already know:
var user = d.Values.FirstOrDefault(u => u.Name == "user6");
var prev = d[user.Rank - 1];
var next = d[user.Rank + 1];
Just need some code to prevent a crash if you find the top or bottom ranked user (look at TryGetValue) |

I think this is what `Array.flat` does, but I like to use the spread `...` operator to spread arrays so then I can join them again.

<!-- language: lang-js -->
var arr1 = [{

I am kind of confused on how to find the number of cycles. Although it appears to be pretty simple.
Is it supposed to be number of cycles = (Clock Rate) * (CPI) * (Time)
or
number of cycles = (Clock Rate) * (Time)
[image shows required information ](https://i.stack.imgur.com/vsBTk.png)
This is the question:
**If the processors each execute a program in 100 seconds, find the number of cycles and the number of instructions for each processor**
i saw 2 solutions which made me confused, that's why i need your help |

Karate uses [Gatling][1] under the hood hence you need to compare Gatling versus JMeter, not Karate versus JMeter and the questions you need to answer are:
1. [Network protocols][2] supported. JMeter out of the box supports more and even more protocols are available via [JMeter Plugins project][3]
2. Distributed execution mode. In JMeter it [comes out of the box][4] and for Gatling you will need to [come up with your own implementation][5]
3. Programming language knowledge required. JMeter allows you to create tests using GUI and provides [recording capabilities][6]. With Gatling you will need to write test logic in Scala, Java or Kotlin.

I am playing with Scrapy and I am able to scrape with it data from different URLs. One thing I am trying to obtain, and so far unsuccessfully, is stats data, particularly `finish_reason` and `elapsed_time_seconds`.
My `testspider.py`'s structure looks pretty standard:
class TestSpider(scrapy.Spider):
name = 'testspider'
def parse(self, response):
...
reason = self.crawler.stats.get_value('finish_reason')
print(reason)
print(self.crawler.stats.get_value('elapsed_time_seconds'))
print(self.crawler.stats.get_value('log_count/DEBUG'))
and on the output is the following
...
None # finish_reason
None # elapsed_time_seconds
75 # log_count/DEBUG

I cannot access some fields from the `def parse` method, perhaps because the script is still running? How do I achieve that? I would like to have direct access to the data in `Scrapy stats` and save it "manually" to the database. How do I achieve that? |

## A leaky abstraction
ActiveRecord tries to cross the chasm between the table based world of your database and objects in your application and stumbles like any ORM. `update_all` is one of the methods that operates in the SQL world instead of on objects like `update` does. While it can take a hash and translate it into simple SQL that doesn't apply to structured data types like JSON.
ActiveRecord only somewhat supports JSON columns - the types are supplied by the database drivers which handle conversion to and from the database to Ruby types but you can't work with the data inside with the ActiveRecord query interface as the JSON operators/functions are very vendor specific.
Having accessors in your model doesn't magically let you update the contents of a JSON object in the database world. Even less so when what you have stored isn't actually a JSON object.
## The foot gun
`store` is an old hack from the dark days before RDMBS systems had structured data types such a JSON and JSONB. It stores serialized data as a string (in a text or varchar type column) and then deserializes it in the application when models are hydrated with data from the database.
If you use `store` with a native JSON column you're storing an escaped string instead of JSON objects. So you have potentially shot yourself in the foot by filling the database with garbage.
It comes with the following warning:
> NOTE: If you are using structured database data types (e.g. PostgreSQL
> hstore/json, or MySQL 5.7+ json) there is no need for the
> serialization provided by .store. Simply use .store_accessor instead
> to generate the accessor methods.
**Do not use it outside of legacy applications.**
# The fix
A first step towards fixing your issue would be to fix any existing data in the table and convert the strings stored into actual JSON which you can work with in the database. You can either do this by using `update_all` and the [database JSON functions][1] or by looping through the data in Ruby if performance is not an issue.
IMHO if your data is structured enough that you're creating accessors for it in the model it isn't unstructured enough to warrant the use of JSON. I would just declare columns and fill them by looping through the junk data once. That gives you normalized data that you can work with in a sane way and you're avoiding an anti-pattern.
If you want to stick with putting what should be columns into a JSON column you would need to use the MySQL specific JSON function to update the data.
Model.update_all('model.settings = JSON_MERGE_PATCH(
model.settings, \'{"unit_of_distance": "miles" }\'
)')

The [bash manpage](https://www.gnu.org/software/bash/manual/html_node/Bash-Variables.html) says that the variable **`OSTYPE`** stores the name of the operating system:
> `OSTYPE` Automatically set to a string that describes the operating system on which bash is executing. The default is system-
dependent.
It is set to `linux-gnu` here. |

I am trying to use the POST method to insert some data from a person with JSON. I am using the code from JS to construct, but when i start the transformation, it sends me:
> "ERROR: invalid character ' ' in literal true (expecting 'e')".
Does anyone know how to solve it?

Some columns are already provided with data from previous step (you can see in the images below), that is why i just repeated the column name in the JS code. Just to let you know, the boolean types of data are the columns: send_email, send_sms and deficiencia.
