I feel lucky that there are so many people ready to help. I did find a method that saved the other partitions and enabled the unallocated for a new D: drive with 930GB. It was so easy I'm feeling rather stupid it wasn't found in my initial search. The tool Disk Management was the key.

Please see the documentation on launch.json.
The attribute console defines what console should be used by the debugger, it could be, in particular, non-default integratedTerminal or externalTerminal. I tried those options — both terminals support terminal input.
However, the documentation says: Many debuggers support some of the following attributes. So, strictly speaking, it depends on a particular C/C++ debugger implementation you use, but I hope they all work with the terminals. Please give it a try and let me know if you have problems.

The issue is likely from the name attribute being a number (232323) instead of a string, and this can cause problems with how browsers and password managers interpret form inputs. Browsers typically expect name attributes to be strings.
Also, use the appropriate autocomplete attributes such as autocomplete="username" or autocomplete="password", etc. this helps browsers autofill behavior
Short Answer
No. In a standard mobile web app (including one built on Wix), there is no reliable or supported way to link users directly to the “Location” section of their device’s Settings app (whether on iOS or Android). You can detect if location is off and prompt them, but you cannot “deep-link” straight into those system settings from the browser.
I will suggest you display Instructions / Guides instead.

You can't assume (as you do seem to be assuming) that the data written by one side using a single send() call will be received by the other side in a single recv() call.
Depending on the amount of data and timing of network packet transmission, it's possible that send() will split your buffer into multiple packets, each of which will get received by a separate recv() call on the other side.
In other words, you need to implement some kind of command/response protocol, incorporating some kind of framing, on top of the byte streams that TCP is giving you.
You could alternatively switch from TCP to UDP, and use UDP packet boundaries for framing.
IMO the most natural algorithm would be to keep TCP, and use newline-terminated commands and responses. Ie, the command ends when you see a newline, not necessarily whenever recv() returns.

For those who prefer VSC, Visual Studio Code, and other IDE's with select your entire line, the best I have managed on this program is settings:
LINE START = " ctrl + ; "
SELECT LINE END = " ctrl + L "
This creates something as close to VSC as I could manage with the two keys to create the action next to each other near ' ctrl + L ' which is the vsc command. Very surprised Eclipse does not have this feature.
Also tried setting SELECT LINE END and SELECT LINE HOME to the same key hoping it would execute both commands at once and select the whole line. No luck! Was looking forward to using eclipse but just have spent couple thousand hours in vsc which i love. If anyone finds a workaround, please let us know.

In my case the issue was with the sheet names. I was using different sheet name with no spaces in in it when they had spaces. Please keep in mind that the message "The requested resource doesn't exist" doesn't always mean the id of the file is incorrect buy if the sheet name is incorrect it might also happen.
How I should be able to use Microsoft Power BI API for delete workspaces? When I created a workspaces linked to service entity profile I did so:
public function createWorkspace($accessToken, $profileId, $workspaceName)
{
$response = Http::withHeaders([
'Authorization' => 'Bearer ' . $accessToken,
'X-PowerBI-Profile-Id' => $profileId,
'Content-Type' => 'application/json',
])->post($this->baseUrl . 'groups', [
'name' => $workspaceName,
]);
if ($response->successful()) {
return $response->json();
}
throw new \Exception('Error creating workspace: ' . $response->body());
}
Then I grant access permissions like this:
public function grantAccessPermissions($accessToken, $workspaceId, $profileId)
{
$response = Http::withHeaders([
'Authorization' => 'Bearer ' . $accessToken,
'Content-Type' => 'application/json',
'X-PowerBI-Profile-Id' => $profileId,
])->post($this->baseUrl . 'groups/' . $workspaceId . '/users', [
'groupUserAccessRight' => 'Admin',
'identifier' => '487eabe2-22ea-4419-b8f9-e7f09fa0b875',
'principalType' => 'User',
'emailAddress' => '###@####.onmicrosoft.com'
]);
if ($response->successful()) {
Log::info('Respuesta de grantAccessPermissions: ' . json_encode($response->json()));
return $response->json();
}
throw new \Exception('Error granting access permissions: ' . $response->body());
}
Right here I send the 'emailAddress' parameter in request body which is 'Admin' of premium capacity assigned to service principal. And the workspace is showing in Power BI Service correctly.
But I can't delete the workspace created.
public function deleteWorkspace($accessToken, $workspaceId)
{
if (empty($workspaceId)) {
throw new \Exception('El Workspace ID no puede estar vacío.');
}
Log::info('Workspace ID que llega a deleteWorkspace: ' . $workspaceId);
$response = Http::withHeaders([
'Authorization' => 'Bearer ' . $accessToken,
'Content-Type' => 'application/json',
])->delete($this->baseUrl . 'groups/' . $workspaceId);
if ($response->successful()) {
return $response->json();
}
throw new \Exception('Error deleting workspace: ' . $response->body());
}
I receive this response: PowerBINotAuthorizedException

Yes, this can happen. Just like how prefetching (where email servers/providers pre-load email content before the user has opened the email) can inflate your open rates, links can also be "clicked" by email servers before actually clicked by a user. This is usually a security measure, where the system is checking the link for safety. But these types of clicks can usually be identified by the system, and thus excluded from the open rates they show you.
I have 9 years experience working at companies that allow people to send marketing emails, in roles ranging from tech support to product management, and I have seen instances where the filtering didn't happen as it's supposed to. These have been low-impact bugs, not very common and pretty quickly fixed. Within email campaigns where this happened, I don't recall specific numbers that were seen in terms of normal vs. abnormal click rates.
If you're sending emails and seeing way more clicks than usual, happening almost immediately, this might be the case for you. I'd suggest comparing like-to-like when looking into this, though - a "reset password" email campaign is going to have way more fast clicks than your standard marketing promo campaign, for example, and audience engagement varies. So look at the history for your particular emails and audience to get an idea of what's likely happening for you.

The issue might be a merge conflict caused by working on the project simultaneously on different machines. This happened to me by having the project open on laptop and desktop at the same time.

The trick is correcting duplicate id's of loading resources caused by the merge conflict.

Issue is most likely related to how ARIA attributes interact with focus managment in nested accordions. when expanding accordion or collapsing focus can inadvertenly move to a descendant and cause parent to interpret this as a collapse.
there are few ways of handling this, not sure what is your use case but you can try at least to use any of these methods to suit your needs
import { Component, ElementRef, ViewChild } from '@angular/core';
@Component({
selector: 'app-accordion',
template: `
<button #accordionHeader (click)="toggleAccordion()">Accordion Header</button>
@if (isExpanded) {
<div role="region">
<p>Content here...</p>
</div>
}
`,
})
export class AccordionComponent {
@ViewChild('accordionHeader') accordionHeader!: ElementRef<HTMLButtonElement>;
isExpanded = false;
toggleAccordion() {
this.isExpanded = !this.isExpanded;
this.accordionHeader.nativeElement.focus();
}
}

CQS: It is a programming principle that says you should separate operations that change data (commands) from those that read data (queries). If you have a method, for instance, it should either return something or update something, but not both.
CQRS: By dividing the design of the entire system into two sections, one for managing commands (writing or modifying data) and another for managing queries (reading data), CQRS expands on this idea. Each side can have its own database or model to optimize how they work.
So, CQS is the basic rule, and CQRS is like an advanced version of it used for bigger systems where you want to handle reading and writing differently.
My name is Michel, and I am a Full Stack Developer & DevOps. I know the question was posted some time ago, but it remains relevant. Based on my experience with WordPress, AWS, and large-scale, high-performance projects, as well as frequent contact with smaller projects and questions from other professionals in the field, I can confidently say that the issue is still valid.
My recommendation for hosting a WordPress application on AWS, based on various tests and projects I manage, is to use AWS Elastic Beanstalk to orchestrate EC2 instances, even if it is a project with just one instance. Elastic Beanstalk significantly simplifies infrastructure management, the deployment process, and maintenance, while also offering advanced scalability control. In some projects, I use auto-scaling, which adds or removes EC2 instances as needed, ensuring scalability and cost optimization.
Regarding architecture, it is entirely possible to run WordPress on multiple load-balanced instances. The key lies in implementing a distributed architecture. While EC2 instances process PHP with NGINX, WordPress media files can be stored in EFS (Elastic File System), allowing sharing and synchronization across all instances. For the database, the best approach is to use Amazon RDS with MySQL or Aurora.
Additionally, to improve performance, I recommend using ElastiCache to optimize database queries and AWS CloudFront to efficiently serve static content. By applying appropriate caching rules for different types of files, it is possible to achieve high performance and significantly reduce the page processing load on each request.
This is an overview of the architecture I have been using and refining over the years, with excellent results in content portals, e-commerce sites, and SaaS platforms based on WordPress on AWS.
If you would like to discuss this topic further, I am available. I hope I have helped clarify your question!
If by project you mean an opened folder or repository, then just put different .vscode/settings.json inside of each project and that should be it
Where did you put empty_values=()?
on MYSQL workbench the solution is SELECT idcategoriaespecifica, nombre FROM table ce WHERE MATCH (ce.column1) AGAINST ('VALUE1 VALUES2')
In the against just put the values you want to search but with a space between them
You can use
summary::marker {
content: none;
}
From my testing, it seems that Railway doesn't support hosting WebSocket connections. If you're looking for an alternative, I recommend using Render: https://render.com/
use this IP - http://10.0.2.2/,
instead of http://localhost/ and http://127.0.0.1/
The stage you mentioned, sfc-eu-ds1-9-customer-stage, is an internal Snowflake stage assigned to your account. This endpoint is used in the backend to connect to the cloud storage service Snowflake uses for your account. Clients use it for PUT/GET operations and to fetch persisted or large query results.
Please note that these S3 buckets are not directly accessible, so Snowflake cannot share the credentials for them.
However, you upload and download files from a Snowflake internal/external stage, you must use the following minimum versions of the NodeJS driver:
Version 1.6.2 to upload files (using the PUT command) Version 1.6.6 to download files (using the GET command)

Portable Nucleotide String Compression: Part I, Endian Enigmas
The following is a discussion of some issues that arise when writing portable code in the context of compressing nucleotide text strings and producing the reverse complement of such strings, i.e. the reverse DNA strand.
Portability across both big- and little-endian architectures is required, so before we discuss compression schemes, let's first look at a little code that exposes the issue of "which"-endian:
main()
{
char c[]="acgta";
unsigned int a[2], i;
for(i=0; i<5; i++) printf("address of c[%d] = %X\n", i, &c[i]);
for(i=0; i<2; i++) printf("%X\n",((int *) c)[i]);
a[0] = ((unsigned int *) c)[0] >> 8;
printf("%X\n",a[0]);
printf("%s\n",(char *) a);
}
The code says to print the address of each byte (%X = hex) of the text string acgta. Then cast the address of the c array to an unsigned int and display how the string is stored in two 4-byte words. Then we take the first 4-byte word, shift it to the right by 8 bits, store it in a[0], and look at it again. Finally we cast the address of the unsigned int a array containing that shifted word to be a character pointer, and see what string we get. On a big-endian machine we get
address of c[0] = 7FFF2F00
address of c[1] = 7FFF2F01
address of c[2] = 7FFF2F02
address of c[3] = 7FFF2F03
address of c[4] = 7FFF2F04
61636774
61002F4C
616367
As one might expect, each successive letter of the string occupies the next higher byte of memory. When we examine the string as a word of memory, we see 61636774 as the first word, e.g. acgt where a=0x61, c=0x63, g=0x67, and t=0x74. The second word is 61002F4C, which is an a, the last letter of the string, followed by the string null terminator (0x00) and whatever junk happened to be in the rest of the word (0x2F4C). The last entry, 0x00616367, is the shifted word with 0s filling in from the left. The 0s look like a null terminator so that when we ask to print out the string that (char *) a points to, we get only a newline from the printf statement.
Now let's look at output from the same code on a little-endian machine:
address of c[0] = BFFFFAD0
address of c[1] = BFFFFAD1
address of c[2] = BFFFFAD2
address of c[3] = BFFFFAD3
address of c[4] = BFFFFAD4
74676361
40000061
746763
cgt
Again, each successive letter of the string occupies the next higher byte of memory. When we examine the string as a word of memory, however, we see the letters reversed. This is sometimes explained by saying that the little endian scheme stores the least significant byte of an integer in the lowest address of a word, and the most significant byte of an integer in the highest address of a word. Big endian schemes do just the opposite. Since my computer prints the contents of a memory word (a number) on the screen in English (from left to right), the most significant byte will always on the left, followed by the lesser significant bytes to the right. For the programmer, it is conceptually easier to think of big endian machines as starting their first word of memory on the left and continuing to the right (like English), while little endian machines start their first word of memory on the right and continue to the left (like Hebrew). On a 32-bit machine this looks like:
Big-endian:
|<--------word0-------->|<--------word1-------->|<--etc-->|
byte0 byte1 byte2 byte3 byte4 byte5 byte6 byte7
a c g t a null
Little-endian:
|<--etc-->|<--------word1-------->|<--------word0-------->|
byte7 byte6 byte5 byte4 byte3 byte2 byte1 byte0
null a t g c a
With this scheme in mind, we can now see why word0 prints out the way it does, and we can interpret the rest of the code output on a
little-endian machine. Shifting the first word to the right results in
byte0 falling off the word, instead of byte3 falling off as in a big-endian machine. The result is what we see, 0x00746763. Now when we ask for the string pointed to by (char *) a, we get cgt because the byte0 a fell off the word, and the 0s that filled in from the left became the null terminator.
The above example looked at something that was already in memory, placed there byte-by-byte from a text string. What happens when we want to put some value into a word ourselves? Look at the next code:
main()
{
unsigned int i = 0x00006100;
printf("%X\n", i);
i = i >> 8;
printf("%X\n", i);
printf("%c\n", *((char *)&i));
}
The output on a big endian machine is:
6100 61
The output on a little endian machine is:
6100 61 a
What happened? Lets look at our mental picture when i is declared and assigned:
Big-endian:
|<--etc-->|<--------word0-------->|
byte3 byte2 byte1 byte0
00 00 61 00
Little-endian:
|<--etc-->|<--------word0-------->|
byte3 byte2 byte1 byte0
00 00 61 00
Both architectures print out the same thing for the integer as initially stored, and when the integer is shifted to the right. The difference happens when the address of i is cast to a (char *), dereferenced, and printed as a character. The big-endian machine prints out its byte0, which is null (we get a newline from the printf statement), while the little-endian machine prints out its byte0, which is the letter a.
Code similar to this can be used in portability scenarios if it is important to determine which type endian-ness some application is running on.
Note that I've used unsigned int in these examples. If an int is signed, then 1s will be shifted in from the left if the leftmost bit is a 1, and we want 0s shifted in no matter what bit pattern is in the word. 0s fill in from the right during a left shift no matter if the
variable is signed or unsigned.
As mentioned at the start of this article, these issues are being discussed in the context of encoding nucleotide text strings on different architectures. The nucleotide alphabet consists of only 4 characters, A, C, G, & T. When manipulating strings of these letters, it is desirable to compress the text strings such that each letter occupies only 2 bits in a word instead of 8. Let's look at some compression code for 2-bit encoding of nucleotide text strings on each architecture, and how to produce the reverse complement of a nucleotide string, i.e. the reverse DNA strand.
Portable Nucleotide String Compression: Part II, Shifty Characters
In Part I, we looked at Endian "Enigmas" in the context of bit shifting on different architectures. We did this because we want to be able to compress nucleotide text strings, made up entirely of just the four letters A, C, G, & T, into words containing 2-bit representations of each nucleotide. Thus a 32-bit word will contain 16 nucleotides, and a 64-bit word will contain 32, in both cases a compression factor approaching 4.
The compression is done simply by taking the 2-bit representation for
each 8-bit ascii character and shifting it into its proper position
within a word. If the bit patterns are A=00, C=01, G=11, & T=10, then on a big-endian machine the string acgta looks like:
uncompressed representation
|<--------------word0-------------->|<--------------word1-------------->|
|byte0---|byte1---|byte2---|byte3---|byte4---|byte5---|byte6---|byte7---|
01100001 01100011 01100111 01110100 01100001 00000000 <------8-bit ascii
a c g t a null
compressed representation, 4 letters/byte
|<--------------word0-------------->|<--------------word1-------------->|
|byte0---|byte1---|byte2---|byte3---|byte4---|byte5---|byte6---|byte7---|
00011110 00000000 00000000 00000000 <------ compressed 2-bit string
a c g t a null padded zeros
Each 2-bit representation was shifted to the left on a big-endian machine. On a little-endian machine, we have to shift the other way:
uncompressed representation
|<--------------word1-------------->|<--------------word0-------------->|
|byte7---|byte6---|byte5---|byte4---|byte3---|byte2---|byte1---|byte0---|
8-bit ascii -----> 00000000 01100001 01110100 01100111 01100011 01100001
null a t g c a
compressed representation, 4 letters/byte
|<--------------word1-------------->|<--------------word0-------------->|
|byte7---|byte6---|byte5---|byte4---|byte3---|byte2---|byte1---|byte0---|
compressed 2-bit string ----------> 00000000 00000000 00000000 10110100
padded zeros null a t g c a
Note that in both cases, an a is 00, composed of the same zero bits used to pad the word. Thus when decompressing, one must know the number of letters that were compressed.
The 2-bit representations could have been found with a lookup table that translates each ascii character into its equivalent 2-bit representation, something like:
array[256];
array['A'] = array['a'] = 0x0; <i>/* bit pattern 00 */</i>
array['C'] = array['c'] = 0x1; <i>/* bit pattern 01 */</i>
array['G'] = array['g'] = 0x3; <i>/* bit pattern 11 */</i>
array['T'] = array['t'] = 0x2; <i>/* bit pattern 10 */</i>
Doing it this way is slow, however, having to do a lookup for each 8-bit character. An examination of the 8-bit ascii representations for the characters reveals that the desired 2-bit patterns for each letter are already unique within each ascii representation, and are case insensitive:
A 0100 0001
a 0110 0001
C 0100 0011
c 0110 0011
G 0100 0111
g 0110 0111
T 0101 0100
t 0111 0100
^^
||
these two columns contain the desired 2-bit code
It is much faster to simply mask out the undesired bits and shift the
desired bits to their proper location. If unc is an array of nucleotides in 8-bit ascii, then the following code fragment shows how to create one word of compressed data from 4 words of uncompressed on a big-endian machine, doing everything in the registers without additional load/stores:
mask shift logical "or"
========== ===== ============
compressed[0] = ( (0x06000000 & unc[0]) << 5) |
( (0x00060000 & unc[0]) << 11) |
( (0x00000600 & unc[0]) << 17) |
( (0x00000006 & unc[0]) << 23) |
((unsigned long)(0x06000000 & unc[1]) >> 3) |
( (0x00060000 & unc[1]) << 3) |
( (0x00000600 & unc[1]) << 9) |
( (0x00000006 & unc[1]) << 15) |
((unsigned long)(0x06000000 & unc[2]) >> 11) |
((unsigned long)(0x00060000 & unc[2]) >> 5) |
( (0x00000600 & unc[2]) << 1) |
( (0x00000006 & unc[2]) << 7) |
((unsigned long)(0x06000000 & unc[3]) >> 19) |
((unsigned long)(0x00060000 & unc[3]) >> 13) |
((unsigned long)(0x00000600 & unc[3]) >> 7) |
((unsigned long)(0x00000006 & unc[3]) >> 1);
masking turns bits off, while a logical "or" turns bits on.
The equivalent code on a little-endian machine looks like:
mask shift logical "or"
========== ===== ============
compressed[0] = ((unsigned long)(0x00000006 & unc[0]) >> 1) |
((unsigned long)(0x00000600 & unc[0]) >> 7) |
((unsigned long)(0x00060000 & unc[0]) >> 13) |
((unsigned long)(0x06000000 & unc[0]) >> 19) |
( (0x00000006 & unc[1]) << 7) |
( (0x00000600 & unc[1]) << 1) |
((unsigned long)(0x00060000 & unc[1]) >> 5) |
((unsigned long)(0x06000000 & unc[1]) >> 11) |
( (0x00000006 & unc[2]) << 15) |
( (0x00000600 & unc[2]) << 9) |
( (0x00060000 & unc[2]) << 3) |
((unsigned long)(0x06000000 & unc[2]) >> 3) |
( (0x00000006 & unc[3]) << 23) |
( (0x00000600 & unc[3]) << 17) |
( (0x00060000 & unc[3]) << 11) |
( (0x06000000 & unc[3]) << 5);
Note the mirror symmetry between the two code fragments.
Decompression is a little trickier because the prefix for a T (0101) is different than for the other letters (0100). We can determine T-ness in a register by doing an xor (^: exclusive or) of the 2-bit extraction with the 2-bit representation for T:
A^T = 00^10 = 10
C^T = 01^10 = 11
G^T = 11^10 = 01
T^T = 10^10 = 00
Only T xor T yields a false bool value. Using this fact, the code on a big-endian machine to decode the first 1/4 of a compressed string could look like:
unc[0] = (((0xC0000000 & compressed[0]) ^ 0x80000000)? /* is it a T? */
(((unsigned long)(0xC0000000 & compressed[0]) >> 5) | 0x41000000):
(0x54000000)) /* the letter T */
|
(((0x30000000 & compressed[0]) ^ 0x20000000)? /* is it a T? */
(((unsigned long)(0x30000000 & compressed[0]) >> 11) | 0x00410000):
(0x00540000)) /* the letter T */
|
(((0x0C000000 & compressed[0]) ^ 0x08000000)? /* is it a T? */
(((unsigned long)(0x0C000000 & compressed[0]) >> 17) | 0x00004100):
(0x00005400)) /* the letter T */
|
(((0x03000000 & compressed[0]) ^ 0x02000000)? /* is it a T? */
(((<unsigned long)(0x03000000 & compressed[0]) >> 23) | 0x00000041):
(0x00000054)); /* the letter T */
Each successive 2-bit pair is masked out of the compressed input and xor-ed with 10. If that boolean is true, it is not a T, and we just shift the 2-bits into their proper place and add the remaining common bits. If it is a T, then we just return a T in the proper location. unc[1], unc[2], and unc[3] are similarly computed with the other 3/4 of the compressed word. For a little-endian machine, the same idea prevails with only different masking and shifting.
The same ideas presented above can also be used to do 4-bit and 5-bit compression, where 5-bit covers the entire alphabet.
Finally, note that it is easy to produce the reverse complement of a compressed nucleotide string. Along a double helix of dna, each nucleotide is paired with its complement, A with T, and C with G. A reverse complement string is the original string read backwards, replacing each letter with its complement. Reading backwards is accomplished by reversing the ordering of the 2-bit units within a word, and reversing the ordering of the words. Producing the complement is accomplished by xor-ing each 2-bit pattern with 10, incidentally the same thing we did above to determine T-ness:
A^10 = 00^10 = 10 = T
C^10 = 01^10 = 11 = G
G^10 = 11^10 = 01 = C
T^10 = 10^10 = 00 = A
Code to produce the reverse complement for a string that exactly fills its final word looks like:
for(i=0; i<length; i++)
{
/* reverse and complement */
rc[i] = (((unsigned long)(0xCCCCCCCC & compressed[length-1-i])) >> 2) |
( (0x33333333 & compressed[length-1-i]) << 2);
rc[i] = ( (unsigned long)(0xF0F0F0F0 & rc[i])>>4) | ((0x0F0F0F0F & rc[i])<<4);
rc[i] = ( (unsigned long)(0xFF00FF00 & rc[i])>>8) | ((0x00FF00FF & rc[i])<<8);
rc[i] = (((unsigned long)(dbrc[i]) >> 16) | (rc[i] << 16)) ^ 0xAAAAAAAA;
}
^ 0xAAAAAAAA complements the entire word at once after it has been reversed. Note that this code works for both big- and little-endian machines. Additional architecture dependent shifting must be done for strings that do not exactly fill their final word, see https://github.com/jlong777/cbl and associated links for more "coding to the metal".
When trying to create a minimal reproducible example as suggested by trincot and ggorlen, I took another look at my original code and realized that the cause of the issue was having a helper function invoke the Puppeteer instance methods without binding this when calling them. Whether or not I was using Puppeteer within a module turned out to be irrelevant.
E.g.,
// I was doing this
function callMethod (func, ...args) {
func(...args);
}
callMethod(browser.newPage);
// And what I really needed to do was something like this
function callMethod (obj, method, ...args) {
obj[method].call(obj, ...args);
}
callMethod(browser, 'newPage');
During my original troubleshooting, I replaced the first couple calls to callMethod() with a direct call to the respective Puppeteer instance method but left all of the other calls to callMethod() intact, obscuring the fact that callMethod() was the true culprit all along.
Lesson learned: Always make a minimum reproducible example, no matter how "simple" you believe your existing code is.
I would like to know if you managed to find a solution for this problem. We are experiencing the same challenge of having over 1000 client's ecommerce sites hosted in our single domain and most are asking for Meta's Pixel integration

Someone else's binary: a .dll provided by a 3RD party who intentionally did not want it debugged.
Our own code: C# running in VS in Debug mode so we can step through our own work.
What we do NOT want: to debug the .dll (that is absolutely NOT our need or care).
What we DO want: to leave the .dll as an UNdecompiled UNexamined UNdebugged black box, exactly as its original creator intended.
What we DO want: to debug our OWN C# code withOUT Captain Obvious (Microsoft Visual Studio Debug mode IDE) halting execution by declaring "Symbol file not loaded" or "No symbol file loaded for .dll" or "Binary was not built with debug information"
We will gladly shower praise on anyone who knows of a way to make VS IDE "Shut Up And Proceed Anyway" withOUT attempting to debug the black box .dll which does not want to be debugged.

Ive been having the same problem! did you find any solutions to this?
How about this? https://github.com/dany74q/ctap-keyring-device
This library provides an implementation of a virtual CTAP2 (client-to-authenticator-protocol) device, which uses the keyring library as its backend.
One may use this implementation as a reference for CTAP2-compatible devices, or to use ones host machine as an authenticator, rather than using an external one.
A common use-case would be to use this library as an authenticator for a webauthn flow, storing keys and retrieving assertions on a machine's configured keyring.
Notepad++ has a plugin named "JSON Tools" that will generate a random json document for the schema file in the active document tab. There are not a lot of options, but it does work well in a pinch.
public class Example {
public static void main(String[] args) {

double d = Double. parseDouble(args[1]);
String msg = args[2];
System. out. println(''i='' + i + '' d='' + d + '' msg='' + msg);

I encountered the same problem under Windows 10/11. After a thorough study of the application stack and its interactions, I was able to assume that this is not a JavaFX problem. The path led to the operating system itself - the driver is waiting for a reaction to a long press interaction(?), which is not present on the program side... or it is not present from the Java machine. A quick solution is to disable touch visualization in the touch driver settings. This is on setting the Pen and Touch settings, disable the Show visual feedback option, hit Apply.

Redshift now has VARBYTE type and functions. So you can now convert base64 string to VARBYTE with TO_VARBYTE(str, 'base64'). Then you can do stuff with this VARBYTE, like in my case I needed to see bit 3 of the first byte
SELECT GETBIT(SUBSTRING(TO_VARBYTE(str, 'base64'), 1, 1), 3) FROM ...

the problem was me creating my own sockaddr_un I though I can create my own structure and I was wrong I though that since in the man page there was
The actual structure passed for the addr argument will depend on the address family. The sockaddr structure is defined as something like:
struct sockaddr {
sa_family_t sa_family;
char sa_data[14];
}
The only purpose of this structure is to cast the structure pointer passed in addr in order to avoid compiler warnings. See EXAMPLE below.

This appears to be a navigation menu. In that case, you do not want to use ARIA menu roles. Get rid of all the role="menu" and role="menuitems". ARIA menu roles are only intended to be used in very specific circumstances, primarily when you are trying to recreate a native operating system menu, which a navigation menu is not. Reference: Don't Use ARIA Menu Roles for Site Nav
Implementing a navigation menu is actually much simpler than people make it out to be.
