Laravel Pulse monitor multiple domains
Hello all,
Is Laravel Pulse able to track multiple domains ? I am running Pulse on a Laravel application and this works nice. Seeing slow queries and exceptions (glad not to many :D ).
However I have multiple Laravel applications, can those application report to a single Pulse installation so that I can see all errors / slow queries etc in a single dashoard ? This gives me a single entry for overviewing issues. Or are there other tools that can archive this.
I know that Sentry etc excists, but as above projects are "hobby" projects, I prefer something free / selfhosted on the server. That's why I like Pulse :) submitted by /u/Noaber

Unrecognized options while configuring newlib

Looking at the config.log file, I believe the issue is that the target is set to "x86_64-linux-gnu" in the configure script even though the target passed is "arm-none-eabi". "mno-unaligned-access" is not an option for "x86_64-linux-gnu".

Dive into the Streamlined Directory Structure in Laravel 11
We think you’ll love the fresh skeleton you start with in a Laravel 11 app that is coming out next week! Newcomers will appreciate the minimalism, and experienced developers upgrading will not experience breaking changes in how a typical Laravel application is structured.
If you want to follow along and experiment, you can create a Laravel 10 and Laravel 11 project side by side. We used the following commands to do so:
# Update the installer
composer global update laravel/installer -W
cd path/to/projects
# Create a Laravel 10 app
laravel new laravel-10-app -n --git --pest
# Crate a Laravel 11 app
laravel new laravel-11-app --dev -n --git --pest
On the surface, the project directory structure looks identical:
However, if you start diving into the subdirectories, the file count has dropped from a fresh Laravel 11 installation by ~ 69 files:
# Fresh Laravel v10 app
$ find . -type f -not -path "./vendor/*" | wc -l
=> 217
# Fresh Laravel v11 app (as of 01/29/2024)
$ find . -type f -not -path "./vendor/*" | wc -l
=> 148
Let's review the most significant updates and see how they compare to a Laravel 10 application so you can be ready for the changes coming to fresh Laravel 11 apps.
The app Directory
The app directory has been slimmed down tremendously, moving the nine middleware that ships with Laravel into the framework and out of the project. Typically, these middleware are not heavily customized, and Laravel 11 will provide other methods to customize built-in middleware and add your own middleware.
The app directory in a fresh Laravel 11 app
Middleware changes are done through the bootstrap/app.php file, which is, according to Taylor Otwell, a “lean routes-esque style file for configuring Laravel” that looks like the following:
return Application::configure(basePath: dirname(__DIR__))
->withProviders()
->withRouting(
web: __DIR__.'/../routes/web.php',
// api: __DIR__.'/../routes/api.php',
commands: __DIR__.'/../routes/console.php',
// channels: __DIR__.'/../routes/channels.php',
health: '/up',
)
->withMiddleware(function (Middleware $middleware) {
//
})
->withExceptions(function (Exceptions $exceptions) {
//
})->create();
You could add an application middleware by adding something like the following in the withMiddeware() closure:
$middleware->web(append: \App\Http\Middleware\ExampleMiddleware::class);
The Kernel.php files are no longer in the Laravel project, and these are handled through the framework bootstrap/app.php file.
You might have also noticed that the Controllers directory only includes one Controller class that doesn’t extend from anything. It’s up to you how you’d like to extend your controllers (or not), but it provides a default abstract Controller class.
The config Directory
The biggest shock for you might be the updated config directory, which has…nothing inside of it (other than the .gitkeep file). You will, however, notice that many more configuration options exist in the .env.example file.
If you want to publish any given configuration file from the framework to customize it, you can do so via the config:publish command:
# config/database.php
php artisan config:publish database
# config/logging.php
php artisan config:publish logging
# Or publish all of them
php artisan config:publish
You are free to only extend the configuration values you care about, and they will be merged with the framework’s defaults so you don’t have to keep all published configuration options in a given file.
Suppose you want to look up configuration values in the framework-shipped configuration. In that case, you can use the Artisan config:showcommand, publish the config, or look it up in the config/logging.php file within the Laravel vendor folder:
php artisan config:show logging
cat vendor/laravel/framework/config/logging.php
The database Directory
The database directory is roughly the same. However, you’ll notice that the migration filenames are prefixed in a way that does not represent a given date but keeps them in order as needed. The create_personal_access_tokens.php migration file is no longer in the project. Personal access tokens are only required if you build an API, which we will cover in the routes directory changes.
Also, the database.sqlite file will be installed by default unless you pick a different database option when creating a new Laravel project.
The routes Directory
The routes directory was also slimmed down only to include the web.php and the console.php routes files. If you want to create an API or use the broadcasting functionality, you can install them via artisan:
php artisan install:api
php artisan install:broadcasting
Those commands will bring in the required migrations, JavaScript, and configuration files. What’s nice about this is that applications that don’t need broadcasting or API routes don’t have to worry about these unnecessary files being in the project.
Laravel 11 routes directory
The test Directory
The test/ directory no longer includes the CreatesApplication trait in Laravel 11 projects. If you upgrade your Laravel 10 project, you can remove this trait, as it’s now provided as part of the base TestCase from the framework.
In a Laravel 10 project, the only thing included in the base TestCase class in Laravel 10 is the CreatesApplication trait, which bootstraps the application when creating a fresh application as part of the setup before each test. You can safely remove this trait (and its usage) once you upgrade existing apps to Laravel 11.

Imcremental data import in Power BI Desktop table
Every day, I need to add (import) 600,000 new rows to this fact table inside Power BI desktop from SQL server data warehouse.
My concern is how can I incrementally import these new data and add it to the already existing one in my Power BI Desktop model.
Simply refresh data will read every day all the 10 million rows which will be time consuming.
I tried to modify the M code of the fact table to get new rows after a specific date but this solution completely erase the already 10 million rows of the fact table in Power BI Desktop.
Below my M code
let
Source = Sql.Database("10.Xx.Xx.Xx", "MY_DB"),
dbo_fact_table = Source{[Schema="dbo",Item="fact_table"]}[Data],
filteredRows = Table.SelectRows(dbo_fact_table, each [date] >= StartDate)

How do I fix the health check issue when deploying rails application on Digital Ocean
The build stage is successful:
But it fails when it gets to the deployment stage and there are no details on this error in the logs.
I tried checking the error logs but instead the server appears to be running.
What i have tried so far:
*
Switched between the scheduled HTTP or TCP under health check in digital ocean.
*
Confirmed if the droplet is live:
Used the rails build pack to create a new application in the droplet:
::: Current build pack::::
Custom Build Command v0.1.2
Procfilev 0.0.4
Ruby: v1.244.3
::::::::::::::::::::::::::::::::
Setup the correct environment variables for the app on the digital ocean console.
RAILS_MASTER_KEY=..correct key ommited deliberately..
RACK_ENV=development
RAILS_ENV=development
RAILS_LOG_TO_STDOUT=enabled
RAILS_SERVE_STATIC_FILES=enabled
SECRET_KEY_BASE=key correct ommited deliberately..
In addition,I am currently on the basic plan which should allow me to deploy a rails application and i also tried setting the app level environment variables but they are were overriden by the env i initially setup when creating a new app.
My setup:
*
Ruby and Rails versions:
ruby 3.2.2 (2023-03-30 revision e51014f9c0) [x86_64-darwin20]
Rails 7.1.3
*
platform configs in gemfile:
gem 'tzinfo-data', platforms: %i[mingw mswin x64_mingw jruby]
group :development, :test do
gem 'debug', platforms: %i[mri mingw x64_mingw]
end (edited)
The App Platform Error Code Reference stipulates that this issue is caused by *
the container not responding to health checks. If a health check is
failing, that means that external traffic is not reaching my service
at the expected HTTP route
*.How do ensure external traffic is reaching my service to resolve this if this is the solution?

Synchronised Environment Variables
I currently have about 4 server instances og a Laravel app all running on separate digital ocean droplets.
I've been thinking of a way to cndtaliswd my environment variables and keep it synchronised across all the servers because I've been doing a lot of updates recently and it's very likely to miss one or two servers.
Is this a problem anyone has faced before and how did you go around it? submitted by /u/_1017e_

The current state of Laravel Herd
Is Laravel Herd going open source or are there plans to monetize it?
i've been looking for something like WAMP on MacOS and it seems Herd is the closest one.
However the fact that it's:
* Not open source ( Developer tools are mostly open source, devs like to know that the software running on their machines is validated by the community. Also it can easily be forked when the need arises )
* No clear monetization strategy ( I assume it not being open source means there are plans to monetize it in the future but this has not been communicated)
* Hasn't been updated in 3 months
* No clear roadmap
For the reasons above, I'm skeptical about the longevity of the project. submitted by /u/MobyFreak

How to comprehensively evaluate the performance of an arm CPU?
* Capabilities at the microarchitecture level, such as integer computing capability, floating-point computing capability, etc.
* Higher level capabilities, such as memory access latency, memory bandwidth limits, frequency fluctuations, etc.
* Actual operation situation, typical benchmark operation of computationally intensive or memory intensive workload
I wonder if there are sound and authoritative test suites, workloads, or methodologies for these three aspects?
Force number to text in R

Flutter-When i am changing value in respiratoryRate case and there i applied a setState after that i want to rebuild 'issue' case
switch (cardioVascularWidget.key) {
case 'respiratoryRate':
VitalComponent? respiratoryRate = widget
.cardiovascularFormModel?.cardiovascularAssessment?.respiratoryRate;
return Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
CustomInputTextFormField(
titleText: respiratoryRate?.title ?? "",
hintText: respiratoryRate?.hintText ?? "",
trailingInputUnitText: respiratoryRate?.suffixValue ?? "",
isTitleRequired: true,
isTitleMandatory: true,

}
In the switch case, you can see there I have a case 'respiratoryRate' in which have CustomInputTextFormField it return value inside onValueChange then i apply a
setState(() { _respiratoryRate = value ; });
and other switch case is 'issue' is there, i want to rebuild issues case

Access denied error using move-item to recursively move folders containing files with specific text
I have a folder tree with a root1\yyyy\mm\dd\hh\uniqueid structure and need to move the uniqueid sub folders into a root2\yyyy\mm\dd\hh tree based on content within a specific json file in each uniqueid folder
After several searches I've arrived at the code below which is correctly identifying the folders I need to move, and creating the root2\yyyy\mm\dd\hh folders to hold the moved uniqueid folders, but it gives an access denied error trying to execute the move cmdlet
$root1 = My-Current-Root-Folder
$root2 = My-New-Root-Folder
(Get-ChildItem -Literalpath $root1 -Recurse -Filter *.json) | Select-String -Pattern content-I-am-looking-for | ForEach-Object {
$folderToMove = (Split-Path -Parent $_.Path)
$destinationFolder = $folderToMove.Substring(0, $folderToMove.Length - 33).Replace($root1 , $root2)
write-host $folderToMove #This correctly displays the source folders I need to move
write-host $destinationFolder #This correctly displays the root2 folder structure to hold the moved folders
If(!(Test-Path $destinationFolder)){
New-Item -Path $destinationFolder -ItemType "directory" #This correctly created the root2 folders for the move
}
move-item -path $folderToMove -destination $destinationFolder -Force
}
The error is like this:
move-item : Access to the path '$root1\2023\10\19\01\uniqueid' is denied.
But if I execute a move-item command explicitly specifying one of the uniqueid folders and the associated root2\yyyy\mm\dd\hh destination, the folder is moved without any issue.
All advice greatly appreciated
Tried wrapping the source and destination in double quotes in case that was needed and also specifying [string] on the source and destinations, but that just gives a different error (cannot find a drive F)

But this does not use fast matrix-matrix operations.
I could also do all right hand sides simultaneously, X=solve_triangular(A,B), but this does not take into account the triangular structure in B.
Finally, I could invert A and multiply with B, X=inv(A)@B, but inverting matrices is usually discouraged from.
Laravel Wallet
Hi!
I recently completed the documentation for my Laravel Wallet package and would like to receive feedback on the implementation, if you would be so kind :)
The main objective of this package is to provide a reliable and convenient mechanism for transactions and balances.

Z-Function. String algorithms. Optimize for large strings
Given a string s. For each i from 1 to |s|, find the number of occurrences of its prefix of length i in the string.
Input:
The first line of input contains an integer q (1≤q≤10^5) — the number of datasets in the test.
Each dataset consists of a string s. The length of the string s is from 1 to 10^6 characters. The string consists exclusively of lowercase Latin alphabet letters.
The sum of the lengths of strings s across all q datasets in the test does not exceed 10^6.
Output:
For each dataset, output |s| integers c1, c2, ..., c|s|, where c[i] is the number of occurrences of the prefix of length i in the string s.
Example
Input:
5
abacaba
eeeee
abcdef
ababababa
kekkekkek
Output:
4 2 2 1 1 1 1
5 4 3 2 1
1 1 1 1 1 1
5 4 4 3 3 2 2 1 1
6 3 3 2 2 2 1 1 1
The task must be solved exclusively using the Z-function, and the total time for a string of length 10^6 characters should not exceed 2 seconds.
My solution looks like this:
#include
#include
#include
std::vector ZFunc(const std::string& s) {
const int sz = s.size();
std::vector z(sz, 0);
for (int i = 1, l = 0, r = 0; i != sz; ++i) {
if (r >= i)
z[i] = std::min(z[i - l], r - i + 1);
while (z[i] + i < sz && s[i + z[i]] == s[z[i]])
z[i]++;
if (z[i] > r - i + 1) {
l = i;
r = i + z[i] - 1;
}
}
return z;
}
int main() {
int n;
std::cin >> n;
std::vector res(n);
for (int k = 0; k != n; ++k) {
std::string s;
std::cin >> s;
res[k].resize(s.size(), 1);
std::vector z = ZFunc(s);
for (int i = 1; i != z.size(); ++i) {
while (z[i]--)
res[k][z[i]]++;
}
}
for (const auto& ivec : res) {
for (int i : ivec)

I'm getting an unexpected Tensorflow ResourceExhaustedError when I try to use model.predict() with a Keras Sequential model
I'm training using an NVIDIA GeForce RTX 2070 SUPER with 8Gb of VRAM, and I have 64 Gb of RAM on my PC.
I've used Keras to create a Sequential model to predict POS-tags. I've used the same model format to train models for text in several different languages. The models all trained alright, and when I run model.evaluate(test_data) they all produce a score. Similarly, when I run model.predict(test_data) most models produce the expected results, but there is one model, for one language, which acts differently.
This one model was trained the same as all the other models, so there should be no difference I think. When I run model.predict(test_data) using this model, at first it seems to be working. It starts applying the model to the dataset:
6/152 [=>............................] - ETA: 19s
It even appears to successfully complete this step, though it never gets as far as producing any results:
152/152 [==============================] - 20s 126ms/step
Unfortunately at this point it hangs and produces the following traceback:
2024-01-05 23:08:38.977923: W tensorflow/core/common_runtime/bfc_allocator.cc:479] Allocator (GPU_0_bfc) ran out of memory trying to allocate 2.61GiB (rounded to 2804106240)requested by op ConcatV2
If the cause is memory fragmentation maybe the environment variable 'TF_GPU_ALLOCATOR=cuda_malloc_async' will improve the situation.

I can't work out why it's only happening with this one model, or why there would be a problem with memory allocation when it works for all the other models. It doesn't seem like it's trying to use a lot of memory either. So why am I getting this error message? And, how can I fix it?
I've tried setting memory growth, but it didn't work:
physical_devices = tf.config.list_physical_devices('GPU')
tf.config.experimental.set_memory_growth(physical_devices[0], True)
I've also reduced batch sizes. This didn't help. I've even gone back and retrained the model in case there was something wrong with the model itself. Still have the same problem with the new model. As a last option, I tried splitting the test set into smaller divisions, running model.predict(test_data) on each of these divisions, then recombining the results of each division. It sometimes successfully predicts the first division, but always runs out of memory and gives me the same error by the second division.
Is there anything I can do?
Get parameters for currently running queries in PostgreSQL
The problem is: We dont know the parameters which were given to the query. We can only see the placeholders $1, $2, etc.
Is there any way to get the parameters for a currently running query?
The only workaround could be to enable the query log and parse the parameters from the query log, but this would be a very dirty and slow solution.
Alpine adds a new build to work with Content Security Policies
Caleb Porzio announced that Alpine.js now has a CSP build that will with environments where CSP is required:
In order for Alpine to be able to execute plain strings from HTML attributes as JavaScript expressions, for example x-on:click="console.log()", it needs to rely on utilities that violate the "unsafe-eval" Content Security Policy that some applications may enforce for security purposes.
In order to accommodate environments where this CSP is necessary, Alpine offer's an alternate build that doesn't violate "unsafe-eval", but has a more restrictive syntax.
One thing to note with this new build is you must Alpine.data:
Since Alpine can no longer interpret strings as plain JavaScript, it has to parse and construct JavaScript functions from them manually.
Due to this limitation, you must use Alpine.data to register your x-data objects, and must reference properties and methods from it by key only.
This new build is available as a CDN or an npm install @alpinejs/csp
See the official documentation for complete details and for detailed instructions.
Note: When asked about Livewire support, Caleb says, "Not yet unfortunately because there is one or two places Livewire relies on eval (wire:click="something('one', 'two')") kinda thing"

Localhost for Mail server?
Curious to see what are the options to run email server locally. I believe I had one with Laragon setup on windows but I wonder if there is anything like that for Mac? Like it would setup SMTP or some similar service locally and all your email would show up there. Any free/open source service like that? submitted by /u/TastyInternet

R: Pattern matching one column to a json string stored in another column
This dataframe contains a columns TX_JAN_2019_DF$AREA (type: numeric) and TX_JAN_2019_DF$DEVICE_HOME_AREA (type: character)
TX_JAN_2019_DF$AREA[1] produces:[1] 481210216382
TX_JAN_2019_DF$DEVICE_HOME_AREA[1] produces a sample of the string (for this benefit of this post, this output is greatly reduced):
"{\"481210216382\":307,\"481210216371\":50,\"481210216381\":43,\"481130137213\":35,\"481210216373\":27,\"481130137222\":21,\"481210216154\":21,\"481210216152\":17,\"481210216133\":15,\"481210216372\":4}"
As you can see the json string is a string of values type character. I need to pattern match the first column TX_JAN_2019_DF$DEVICE[1], to see if the second column element TX_JAN_2019_DF$DEVICE_HOME_AREA[1] and the json string stored in that element contains the pattern and if it does, what is the number after the colon (307 for example in the first element).
Then of course do this for all columns TX_JAN_2019_DF$DEVICE_HOME_AREA
I'm at a loss on how to do this as the json adds a complication to normal pattern matching. I've looked at the jsonlite library, but the examples are not much help.
Thank you in advance
Use Model shouldBeStrict when starting a new Laravel app
So you have an idea for a brand new app. You install Laravel, you're ready to get started. What's the first thing you should do?
For me, I open up the app service provider and go down to the boot method and set the global Model::shouldBeStrict():
public function boot(): void
{
Model::shouldBeStrict();
}
With this turned on it does the following:
public static function shouldBeStrict(bool $shouldBeStrict = true)
{
static::preventLazyLoading($shouldBeStrict);
static::preventSilentlyDiscardingAttributes($shouldBeStrict);
static::preventAccessingMissingAttributes($shouldBeStrict);
}
This does three things:
* Prevents lazy loading
* It prevents silently discarding attributes.
* It prevents accessing missing attributes.
Preventing Lazy Loading
Here is an example of lazy loading.
$articles = \App\Models\Article::get();
foreach ($articles as $article) {
echo " * " . $article->user->name . "
\n";
}
If you run this, it will output what you expect. However, it’s lazy loading the user relationship, causing a new query for every loop.
With shouldBeStrict turned on instead of running the code you’ll get an error giving you instant feedback:
Attempted to lazy load [user] on model [App\Models\Article] but lazy loading is disabled.
Prevent Silently Discarding Attributes
Here is an example showing trying to update an attribute that is not fillable:
$user->fill(["remember_token" => "bar"]);
Now this will return an exception:
Add fillable property [remember_token] to allow mass assignment on [App\Models\User].
Prevent Accessing Missing Attributes.
Let’s pretend we are trying to display a property on the User that may not exist:
{{ $user->nonexistant }}
By default, Laravel will just not display anything because the property is not found, but with Strict mode turned on you get:
The attribute [nonexistant] either does not exist or was not retrieved for model [App\Models\User].
This really helps in cases where you might make a spelling mistake like:
{{ $user->emial }}
Now, you’ll get instant feedback you messed up.
Turning on Model::shouldBeStrict() is now the first thing I do on every app, and it helps prevent me from making basic mistakes that could be harmful to the app later on.

Generate PDFs in Laravel from Blade Views
The Laravel PDF package by Spatie provides a simple way to create PDFs in Laravel Apps. It uses Blade views to render HTML and create a PDF from that view using Browsershot. This opens up the ability to use modern CSS tools like Grid and Flexbox, modern CSS frameworks like Tailwind, and even JavaScript code for things like rendering charts.
Here's a basic example of creating a PDF and returning it from a controller, passing variables to the template that you can use to dynamically render the PDF data:
use Spatie\LaravelPdf\Facades\Pdf;
class DownloadInvoiceController
{
public function __invoke(Invoice $invoice)
{
return Pdf::view('pdfs.invoice', ['invoice' => $invoice])
->format('a4')
->name('your-invoice.pdf');
}
}
At launch, the Laravel PDF package supports the following features:
* Render PDFs from Blade templates or an HTML string
* Save a generated PDF to a Laravel disk
* Run JavaScript code when the PDF is created
* PDF testing fake with powerful assertions
* Generate PDFs on Lambda via Laravel Sidecar
* Advanced PDF control with tools like page breaks, Browsershot customization
* And more...
Creating PDFs in Laravel with Blade will make generating beautiful custom PDFs easier and more powerful than ever! To get started, check out the official Laravel PDF documentation. The source code is available on GitHub at spatie/laravel-pdf.

DataSnap - how to change SELECT query to show different data?
ClientDataSet1.CommandText := 'SELECT * from table_name WHERE autoid = 10';
ClientDataSet1.Open;
ClientDataSet1.Refresh;
But when I want to change this, the TDBGrid is not showing different data, it still shows data from my first code:
ClientDataSet1.CommandText := 'SELECT * FROM table_name WHERE autoid = 1';
ClientDataSet1.Open;
ClientDataSet1.Refresh;
How can I fix it?
Is there any way to observe all data attributes in a custom component?
class MyComponent extends HTMLElement {
static get observedAttributes () {
return ["data-one","data-two","data-three",so forth...]
}
}
This component could in theory be assigned an arbitrary number of data attributes, so there's no way to predict exactly how many there would be, yet I need the component to do stuff every time a new data attribute is assigned to it, is there any way to do it? having to put into the array returned by "observedAttributes" the specific name of every attribute seems really restrictive
As a bonus, is there any way to observe attributes that don't have a specific name but follow a certain pattern? (e.g. they match against a regex string or something like that)
And as an extra bonus, is there any way to observe all attributes? (I know they made this not be the default behavior due to performance factors, but still it would be good to be able to enable it if needed)

Laravel SQS DLQ
Hey laravel folks,
We are currently in the process of migrating to AWS and we are thinking about using SQS for the queue driver. We created DLQ for the queues we created but it seems it's not needed since laravel internally stores the failed jobs in the `failed_jobs` table in database? Is my assumption correct and should we just not create DLQ on sqs for the queues?
Thank you! submitted by /u/g00g00li

How to fill out existing PDF?
Hey all. Looking for some help.
I’m building an application that needs to dynamically generate 1099 tax forms for contractors. I’d love to be able to just lay text on top of the existing PDF form from the IRS, even if it’s just by using x and y coordinates to target the specific fields, since the file is not directly editable.
Is there an easy way of doing this? I’m very familiar with the Laravel-dompdf package (
https://github.com/barryvdh/laravel-dompdf), but I don’t believe this is possible.
Should I just build my own version of the IRS form and generate the entire thing from scratch? I’m just not sure if that’s frowned upon by the IRS and/or compliant.
Any direction would be appreciated. Thanks! submitted by /u/brycematheson

i want to create a new order with 2 products and corresponding amount specified. here is how i implement it:
public class OrderEnpoint
{
public static void Map(WebApplication app)
{
app.MapPost("/order", async (DkdbContext db, OrderDto orderRequest, UserManager userManager) =>
{
if (orderRequest == null || string.IsNullOrEmpty(orderRequest.UserId))
return Results.BadRequest();
var user = await userManager.FindByIdAsync(orderRequest.UserId);
var newOrder = new Order
{
UserId = orderRequest.UserId,
CreatedBy = user?.UserName,
UpdatedBy = user?.UserName,
};
await db.Orders.AddAsync(newOrder);
await db.SaveChangesAsync();
var _OrderDetails = orderRequest.ProductOrderList
.Select(e => new OrderDetail
{
OrderId = newOrder.Id,
ProductId = e.ProductId,
Amount = e.Amount,
}).ToList();
await db.OrderDetails.AddRangeAsync(_OrderDetails);
await db.SaveChangesAsync();
return Results.Created();
});
}
}
here is my data transfer object class:
public class OrderDto
{
public string UserId { get; set; } = string.Empty;
public List ProductOrderList { get; set; } = [];
}
public class OrderRequest
{
[Required]
public int ProductId { get; set; }
[Required]
public int Amount { get; set; }
}
When i debug this code, I am able to see order record created in Orders table, but not in OrderDetails. am using postgres as database. here is what the error look like:
---> Npgsql.PostgresException (0x80004005): 23502: null value in column "UserId" of relation "Orders" violates not-null constraint
DETAIL: Failing row contains (15, null, 1, 2024-01-01 14:07:25.091254+00, 2024-01-01 14:07:25.091254+00, null, null).
Exception data:

i expect to be able to create a new Order with associated OrderDetail with amount respectively. I am looking for solutions, am glad if someone can help. thank you.
Compression of randomly ordered non-repeating incremental integers
I know that compressing random numbers is theoretically not possible, but I'm wondering if it's possible for this case since each number only appears once and you basically just need to compress the order of the numbers somehow... Please don't be harsh, I'm not an expert in this field. Also, any tips for python implementations would be greatly appreciated! :)
Thanks in advance.
Does a timer-triggered Azure function execute if an instance of the function is already executing?
Suppose you manually execute the function via the Function Menu Blade -> Code + Test -> Test/Run, as shown at the bottom of this message. What happens if this manual execution of the function is still running when the time specified in the TimerTrigger attribute arrives?
* Will the manual execution be interrupted by the timer-triggered execution?
* Will the manual execution prevent the timer from triggering a new execution of the function?
* Or will a new instance of the function be kicked off when the timer triggers it, running in parallel with the existing manual execution?
Calling different functions of a DLL from different threads simultaneously segfaults or gives a status_stack_buffer_overrun
After implementing a parallel function to analyse multiple deals simultaneously (AnalyseAllPlaysBin, link to the docs) and writing a little test for it, cargo test started failing with:
exit code: 0xc0000409, STATUS_STACK_BUFFER_OVERRUN
or with:
exit code: 0xc0000005, STATUS_ACCESS_VIOLATION
note: test exited abnormally; to see the full output pass --nocapture to the harness.
Segmentation fault
I was a bit surprised and I dug a bit to understand the problem. I found out that the reason for the failure was cargo running the tests in parallel, and I think simultaneous calls mess up with the DLL, making it segfault.
Using cargo t -- --test-threads=1 solves the problem, but since I'm writing a library I hope to use for an application in the future, I would like to understand the problem and solve it in some way. I'm not planning to make multiple simultaneous calls to the DLL but the problem still bothers me.
I cannot provide an MWE but I'll give some code for reference:

I could wrap the DDSAnalyzer in an Arc and then lock it for the duration of the external function call. I think this should work (didn't have time to try it) but I don't know if it is the correct approach.
I would like to ask two things:
* Why I get those errors in a multithreaded situation?
* Would using a Arc work? Is it the correct solution or should I do something different?
Thanks to everyone!
