CUDA Compute SM Throughput improvement for multiple loops

I'm interested in exploring different approaches to enhance the Compute (SM) Throughput of a CUDA code. It would be great to discuss with individuals having a good understanding of CUDA optimizations. To ensure a fruitful exchange and better comprehension, I kindly request that you also share code or algorithm snippets. If you are not familiar with CUDA optimizations, please feel free to disregard this request. Thank you!


First, let me describe the serial code. In the C code provided below, within both the first and second loops, we calculate 655 by 655 independent determinants. We then utilize weighted contributions to perform a summation over the second loop. The determinants are computed using LU decomposition. Ultimately, the objective is to compute the weighted contributions of these determinants.
I want to know which parallelization implementation would be better. That is, if there are multiple for loops, which loop should I consider for block and thread computation for time efficiency?


I have provided the details of these loops in the code below.
read_index(ind, ind_u, ind_d); // generates index for qc, det_store used later
int U=6;

for (it = 1; it < 64; it++) { // first loop, can be serial run
double sum1 = 0.0;
double sum2 = 0.0;

for (ii = 0; ii < 24*24*24; ii++) { // second loop, can be made parallel in blocks; values 24^3, 32^3, 48^3, 96^3}

read_qc(qc); // generates 4D qc array, different with each ii; size 3 * 3 * 4 * 4

int al[U], a[U], ap[U], alp[U]; // U=6
double _Complex A[U][U],AL[U][U],AU[U][U];
double _Complex det_store[655][655];

// every 655*655 has a A[6][6]
// det store [655][655]

int i,j,k,l;
for (i = 0; i < 655; i++) { //idx parallelize no dependency on above

for (k = 0; k < U; k++) { // al[k=U=6][i=655]
al[k] = ind[i][k]; //
a[k] = ind[i][k + U];
}

for (j = 0; j < 655; j++) { //jdx

for (k = 0; k < U; k++) {
alp[k] = ind[j][k];
ap[k] = ind[j][k + U];
}

for (k = 0; k < U; k++) {
for (l = 0; l < U; l++) {
A[k][l] = qc[a[k]][al[k]][ap[l]][alp[l]]; //Assigning the matrix element
}
}

Calculating the determinant using LU decomposition and storing them
LU_Decomposition(A, AL, AU);
det_store[i][j] = calculate_determinant(AU);
}
}

double _Complex temp;
//Uses above compute det
//
for (i = 0; i < 2716; i++) { //
for (j = 0; j < 2716; j++) { //
temp = weight[i]
* weight[j]
* det_store[ind_u[i]][ind_u[j]]
* det_store[ind_d[i]][ind_d[j]]; //combining the stored determinants using info from comb_he4.txt files
sum1 = sum1 + creal(temp);
sum2 = sum2 + cimag(temp);
}
}

}
printf("%d\t%.16E\t%.16E\n", it, sum1, sum2);
}



I am exploring various ideas and code snippets for an efficient implementation with minimal time stamp. If you can suggest improvements to LU_Decomposition functions with some CUDA libraries, that would also be helpful. Here is the LU_Decomposition function
void LU_Decomposition(double _Complex A[U][U], double _Complex L[U][U], double _Complex Up[U][U]) {
for (int i = 0; i < U; i++) {
// Upper Triangular Matrix
for (int k = i; k < U; k++) {
double _Complex sum = 0;
for (int j = 0; j < i; j++) {
sum += (L[i][j] * Up[j][k]);
}
Up[i][k] = A[i][k] - sum;
}

// Lower Triangular Matrix
for (int k = i; k < U; k++) {
if (i == k) {
L[i][i] = 1; // The diagonal elements of L are 1
} else {
double _Complex sum = 0;
for (int j = 0; j < i; j++) {
sum += (L[k][j] * Up[j][i]);
}
L[k][i] = (A[k][i] - sum) / Up[i][i];
}
}
}
}



I have parallelized the code mentioned above using CUDA by implementing a global kernel called gpu_sum. This kernel stores the reduced sum values for each iteration of the second loop, as described in the preceding C code. Below is the CUDA kernel
__global__ void gpu_sum(cuDoubleComplex *d_tqprop,
cuDoubleComplex *d_sum_nxyz,
int *d_deg_ind_up, int *d_deg_ind_down, float *d_deg_ind_weight,

WRN This kernel grid is too small to fill the available resources on this device, resulting in only 0.1 full
waves across all SMs. Look at Launch Statistics for more details.



My grid consists of 64 blocks, with each block containing 64 threads. However, when I increase the grid size, both the compute streaming multiprocessor (SM) throughput decreases and the time taken increases.

Is there a way to use awk to count the number of rows between 2 flags and input that number into a specific field?

I have a set of data that consists of seismic wave travel times and their corresponding information (i.e. source that produced the wave and the time for that wave arriving at each geophone along the spread). I am trying to format the data to fit my code in order to do some tomography using the data, but I'm still relatively new to awk. I am at a point where I need to now insert the number of receivers for each shot/source into the line of shot/source information, but its a variable amount each time. Is there a way to have awk count the number of rows and insert that into the proper field?


My data is formatted like the following.


Each line that documents a source/shot:


s 0.01 0 0 -1 0


Every other line that follows the source/shot information:
r 0.1 0 0 1.218 0.01
r 0.15 0 0 1.214 0.01
r 0.2 0 0 1.213 0.01




I can use the "s" as a flag for the shot lines, and I would like to count the number of "r" lines for each source/shot and insert that number into the corresponding "s" line.


The number of "r" lines for each "s" line varies greatly.


Given this sample input:
s 0.01 0 0 -1 0
r 0.1 0 0 1.218 0.01
r 0.15 0 0 1.214 0.01
r 0.2 0 0 1.213 0.01
s 1.01 0 0 -1 0
r 0.05 0 0 1.159 0.01
r 0.1 0 0 1.127 0.01
r 0.15 0 0 1.106 0.01
r 0.2 0 0 1.115 0.01
r 0.25 0 0 1.107 0.01



The expected output is:
s 0.01 0 3 -1 0
r 0.1 0 0 1.218 0.01
r 0.15 0 0 1.214 0.01
r 0.2 0 0 1.213 0.01
s 1.01 0 5 -1 0
r 0.05 0 0 1.159 0.01
r 0.1 0 0 1.127 0.01
r 0.15 0 0 1.106 0.01
r 0.2 0 0 1.115 0.01
r 0.25 0 0 1.107 0.01



Note the 3 as $4 in the first s line and the 5 as $4 in the second one.


The counted number of rows should be in the 4th column of each "s" line (asterisks here).


My experience with awk is limited to just rearranging/indexing columns, so I don't really know where to begin with this. I've tried googling help with awk, but it's very difficult to find answered awk questions that actually pertain to my specific situation (hence why I have decided to ask it myself).


I'm also new to using stackoverflow, so if I need to include more example data, please let me know. My data consists of approximately 4000 lines.


EDIT: The reason the desired result has slightly different data to the example of my data is because there are hundreds of lines for each "s" line and including that in the question seems excessive. I have cut out the majority of the data for ease of reading.

Disable Jupyter Notebook cell only for whole notebook run

I don't know if it is possible, but I have a Jupyter notebook where I'd like to disable some cells in case of a whole run.
That is, 'Run All' would jump over these cells and not trigger them, but they could still be used if ran alone (e.g. with Ctrl+Enter) without changing the code.


I know %%script false --no-raise-error does the trick, but you need to manually change a constant to re-enable the cells when you need them. Ideally, I'd not have to change anything in the code.

what do you do with model names, etc when the project is not in english?

I'm working on a project to manage specific legal orders in a country where english is not the language.

Although it's possible to translate some names in english, it becomes a little weird in some situations. For example a law requires to compile a form, it's weird if I translate the name of the form from the original language name into english, but it's also weird to have so much code in a language that is not english.

What do you do in these cases? submitted by /u/MobilePenor

cross-table query but filter doesn't works

I have two table,custom(click to show picture) gateway(click to show picture). custom.gateway_id's (pk) value is set as gateway.id
When i give a parameter(ex: 1 )The query is intended to retrieve data from CustomModelSerielPort where CustomModelSerielPort.gateway_id (ex:1)_matches Gateway.id (ex:1), and the data is only returned if Gateway.is_partner_ipc is equal to 1.
def list_serial_port(gateway_id: int, db: Session):
result = {"item_list": []}
serial_ports = (
db.query(CustomModelSerielPort.id, CustomModelSerielPort.path)
.join(Gateway, CustomModelSerielPort.gateway_id == Gateway.id)
.filter(Gateway.id == gateway_id)
.filter(Gateway.is_partner_ipc == 1)
.all()
)



If i give a parameter(ex: 3), i shouldn't get any data because Gateway.is_partner_ipc ==0,
However i still can get data, just like filter doesn't work, and if i change my condition to
.filter(Gateway.is_partner_ipc == 0)



I expect to get data when give a parameter(ex: 3) but no data when give a parameter(ex: 1 ), however both wont get any data, do anyone now what wrong with my code, thank a lot.

Used this (

Is there any good tutorial that is handling that all in the frontend? Any articles to read that you can suggest? Really want to learn to work with jwt in a professional way, and store/use it as an httpOnly cookie if possible. Thanks for your help 😁👍 submitted by /u/IngloriousBastrd7908

How to completely overwrite previous print with a new one? [duplicate]

I have to print a progress status, so update a print with a new one. I read many post that says you have to use "\r", so I tried this: print(string, end="\r", flush=True).


The problem is that when the previous printed string is bigger than the second one, some stuff of old print will reamins in the new print.


Here's the full code:
import time

long_string = "AAAAA"
short_string = "BB"
c = 0
while True:
if c % 2 == 0:
print(long_string, end="\r", flush=True)
else:
print(short_string, end="\r", flush=True)
c += 1
time.sleep(1)




I would expect that in the if it would print "AAAAA" and in the else it would print just "BB", but instead, in the else, it prints "BBAAA" because the "A" remains from previous print. Here's what I mean. I would like it would be just "BB" instead of "BBAAA".


I saw this post answer Python: How to print on same line, clearing previous text? so I tried to use os.sys.stdout.write('\033[K' + long_string + '\r') instead of print, but I still have the same problem and it also print a strange character


How can I completely delete previous clean and make a new one without traces of the old one?


Edit:


@Thierry Lathuille
Here's the full code with the second solution:
import time, os

long_string = "AAAAA"
short_string = "BB"
c = 0
while True:
if c % 2 == 0:
os.sys.stdout.write('\033[K' + long_string + '\r')
else:
os.sys.stdout.write('\033[K' + short_string + '\r')
c += 1
time.sleep(1)



It produces this output





I'm testing it in Windows 10 cmd.


Edit 2:
I said that the solution of "\r" didn't work and you closed my question and said that it has been answered in that thread. Are you kidding me right? Please open it again, that solution doesn't work, I already said it, that thread's answeres doesn't work to me and I explained why.

how would you approach baselining models and all of their relations?

I've been tasked with one of the more challenging things I've had to do in my 18 years+ career and as I try to wrap my head around the best approach to solve this, I thought I would ask here as well to see if I can gain anything from outside perspectives.

Hopefully this is allowed, I know it speaks of a specific problem, but it's also a general problem that others might have to deal with at some point so hoping that this thread could be of some use to others in the future.

In my project I have models who contain many nested relations, all of which themselves contain many nested relations. Including many pivot many-to-many relations. I've been tasked with making it possible to save a snapshot of the top level model, including all of its recursive nested relations. These snapshots, also called baselines or versions, can then be loaded at a later time. They can never be edited however, they are frozen in time.

My first approach was to create a new table for this and save the model and all of its recursive relations as json, with the idea that I could then later hydrate that json back into models and return them via my API. This is proving to be quite tricky as the process of re-hydrating my complex json into models and their relations is cumbersome and feels hacky. The idea with this approach is that I could have my snapshots contained and would not have to pollute my database with tons of "cloned" records.

My second approach would be to create duplicate copies of my models and all their relations whenever a snapshot is created. This feels like it would indeed work, but would result in potentially lots of extra rows, though that in itself shouldn't be much concern.

I was wondering if anyone can think of a better approach to my problem? Or if either of my two above approaches seem sound and valid?

Just thought I would pick some brains! Many thanks for any insight! submitted by /u/spar_x

VSCode IntelliSense autocomplete suddenly stopped working with node modules

I'm trying to make a steam bot with JS, and IntelliSense does not work.





I have my SteamUser object declared:
const SteamUser = require("steam-user");
const client = new SteamUser()



It recognizes the logOn function:





But IntelliSense doesn't work. I tried restarting VSCode, entering command pallete and using the Developer: Reload Window command, but to no avail.


In a discord.js project IntelliSense also doesn't work:





I have run npm install:





Here is my package.json:

EDIT: Just found out that local requires also don't work.


Example:
const config = require("./config.json")






config.json:

Conditionally Assert Throwing An Exception in Pest

---



Pest recently added the throwsUnless() method in Pest v2.24 to conditionally verify an exception if a given boolean expression evaluates to false.





This method is the counterpart to the throwIf() method, which conditionally verifies an exception if a given expression is true:
test('example 1', function () {
// Test that only throws an exception for the mysql driver...
})->throwsIf(DB::getDriverName() === 'mysql', Exception::class, 'MySQL is not supported.');

test('example 2', function () {
// Test that throws unless the db driver is mysql...
})->throwsUnless(DB::getDriverName() === 'mysql', SomeDBException::class);



For example, let's say that you have a PHP package that supports various PHP extensions for manipulating images. Your CI environment might support and test both gd and imagemagick; however, other environments might only support one or the other:
test('gd wrapper can create an image', function () {
$image = imagecreate(width: 200, height: 200);
imagecolorallocate($image, 255, 255, 255);
imagepng($image, '/tmp/new_image_gd.png');

expect(file_exists('/tmp/new_image_gd.png'))->toBeTrue();
})->throwsUnless(extension_loaded('gd'), \Error::class);

test('imagemagic wrapper can create an image', function () {
$image = new Imagick();
// ...

})->throwsUnless(extension_loaded('imagick'), \Error::class);



The throwsIf() and throwsUnless() methods also support callables if you prefer that style or have some custom logic that you want to use to determine if the test should throw an exception:
test('example test with callables', function () {
$image = new Imagick();
// ...
})->throwsUnless(fn () => class_exists(\Imagick::class), 'Class "Imagick" not found');

Write Single Page Applications using Laravel Splade

---



Laravel Splade, created by by Pascal Baljet, is a super easy way to build single-page applications (SPA) using Laravel Blade templates. Splade makes it easy to create modern, dynamic web applications that are a joy to use.





Splade provides useful Blade components that are enhanced with renderless Vue 3 components out of the box, such as the Component component. It provides that SPA-like feeling, but you can use Blade, sprinkled with interactive Vue components when required.


As you can see, in the default installation, the components fetch the page data via XHR and provide that SPA snappy feel without full page reloads.





You can use both Blade and Vue markup. Here's an example from Splade's component. Note the v-show directive and @click listener from Vue, and the Blade-specific component and variable usage {{ }}:

{{ $blog->full_content }}




{{ $blog->excerpt }}
Expand





If you need Custom Vue components, Splade has your back, and you can even utilize Server Side Rendering (SSR) to improve performance in your application.


If you also want to use Laravel Breeze or Laravel Jetstream, Splade provides starter kits for both. Splade also provides useful components out of the box you can use to get started quickly, with or without using the starter kits:



* Forms

* Links

* Events

* Flash

* Modals

* Table

* Teleport

* Toggle

* Transition

* And more!






You can get started with Splade quickly by checking out the homepage and accompanying documentation on splade.dev. You can also dive deeper and learn How Splade works under the hood.

Inertia and React or Vue

Hi just checking your thoughts on whether to learn React or Vue, I want to learn React as it may be better to find work and it has a larger ecosystem but my issue is is there are not a lot of tuts for Laravel and React with Inertia, do you have any recomendations for tuts? Also, what are your guys thoughts on Vue vs React with Laravel?

Here is the Reddit post I read that says they are finding it hard to get jobs with Vue.

Laravel 9 Upgrade: Write Operations Now Overwrite Existing Files

Per the v9 upgrade guide, "write operations such as put, write, and writeStream now overwrite existing files by default."

I'm not exactly sure what "overwriting existing files" means in this context. From what I've observed, Storage::put() operates the same way on both Laravel 8 and 9. That is, if the file exists, then put() replaces that file's contents with what's passed into the $contents argument -- it doesn't append the contents to the file, nor does it delete the original file and create a new one (it modifies the original file).

I'm trying to upgrade our Laravel 8 app to version 9, and this is the last item on the checklist that I have to get through. I was stumped because I'm not noticing any difference in the behavior of Storage::put() between v8 and v9.

Can anyone provide any context, insight, or example to demonstrate? submitted by /u/mattk1017

How do you handle small actions?

If you have a pretty basic web app, you will probably have only CRUD. However, as things start to get bigger, you might have a lot of components and each component might have a lot of actions.

For exemple, a blog post might have a "Publish" button. But you might want to "Unpublish". And then you might want to just update the publication date.

I feel like it starts to get cumbersome if you have to create a route for each small action. In Livewire, this isn't an issue because of the way components work. But in Inertia, I have close to 100 controllers, most being small actions like publishing and unpublishing.

What is the best way to organize these small actions? submitted by /u/AsteroidSnowsuit

Since when did Laravel fill ONLY database fields into a Model?

I recently upgraded a Laravel application and came across some strange bugs. It turns out, the fill() method on models doesn't fill all fields anymore!

Yes, I'm aware of the $fillable and $guarded properties. In my model I don't have fillable set and have guarded set to ['id', 'created_at', 'updated_at']. So it should fill any properties except those three. In the past this worked fine, but now it only fills the fields that explicitly exist in the database. Laravel even runs a separate query to get those fields.

In my case, I had a "location" field with a dropdown and an "other" option to write in freetext. So the form would come with location=other and location_other=customtext. The DB would store "customtext" in the location field. But I can't fill the model and then copy "location_other" over, because the latter doesn't get filled.

When did this change? I never saw this listed anywhere in the documentation. submitted by /u/Disgruntled__Goat

Compiler Not Recognized (GCC for Visual Studio Code)

Despite installing the compiler and adding the path to my user environment variable path, the compiler isn't recognized when I test it by checking the version through terminal on VS or command prompt.








For some reason, the path changes from C:/msys64/ucrt64/bin/ to C:/msys64/mingw64/bin/ after I reopen it.


File location on computer (path that was added to environment variable)

Laravel Breeze with Volt Functional API

---



The Laravel team released the Livewire + Volt functional stack for Breeze. This increases the Breeze offering to six stack variations, offering a tremendous amount of freedom to stacks that are emerging in the Laravel ecosystem:



* Laravel Blade

* Livewire with Volt Class API

* Livewire with Volt Functional API

* Inertia (React)

* Inertia (Vue)

* API-only






Getting Started with a New Project




If you want to install the Breeze + Volt functional API while creating a new Laravel project, all in one go, you can run the following:
laravel new --pest --breeze --git --dark \
--stack=livewire-functional \
breeze-functional-demo



Note: at the time of writing, the installer doesn't support livewire-functional unless you require dev-master. Likely, you can wait for the installer to get a release, or you can run
# Normal update once the release is created
composer global update laravel/installer -W

# For the impatient
composer global require laravel/installer:dev-master -W



If you prefer to install after-the-fact, you can run the following:
laravel new example-project
cd example-project
composer require laravel/breeze
php artisan breeze:install



Then you can follow the prompts to select the stack, include dark mode support, and pick the test suite (Pest or PHPUnit):

R - In a for loop iterating through columns df[[i]] if a data frame, how do I print the name of column df[[i]] for each loop?

I'm trying to use a for-loop to iterate through the columns of a data frame, and for each loop print out the name of the column on each loop before the operation is performed (namely checking if there are missing values for that column).


I have tried all I can think of, but haven't had any luck so far.


This was my best guess, but it just returns NULL for the column name (I'm guessing because once I've extracted the data of the column it's already a nameless vector?).
for (i in seq_along(df)) {
# Print column name
print(colnames(df[[i]]))
# Print sum of missing values for each column
print(sum(is.na(df[[i]])))
# Print NA value rows
}



Output is as follows:
NULL
[1] 70
NULL
[1] 0
NULL
[1] 0
NULL
[1] 0
NULL



What can I do to print the column name for each pass?

AWS Glue Python Shell Upgrade Boto3 Library without Internet Access

The default version is very old and hence all the API's does not work


For eg pause_cluster() and resume_cluster() does not work in AWS Glue Python Shell due to this older version

Similarly for many other product features.


Additionally, we don't have to Glue internet access by security and hence need a solution based on s3 storage libraries

How to create a customized Error using TypeScript and node.js?

I am new to TypeScript and now working on a personal project, developing an API using TypeScript + node.js + Express.
What I want to do is to create a customized Error that contains some extra properties over the built-in Error. For instance, to handle an inexsitent url/endpoint, I implemented the middleware as
const app = express();
//... skip some imports and basic middlewares
app.use("/api/v1/events", eventRouter);
app.use("/api/v1/users", userRouter);

interface IError extends Error {
status: string;
statusCode: number;
}

app.all("*", (req: Request, res: Response, next: NextFunction) => {
const err = new Error(`Can't find ${req.originalUrl}.`);
(err as any).status = "fail";
(err as any).statusCode = 404;
next(err);
});

app.use((err: IError, req: Request, res: Response, next: NextFunction) => {
err.statusCode = err.statusCode || 500;
err.name;
err.status = err.status || "error";
res.status(err.statusCode).json({
status: err.status,
message: err.message,
});
});



I had to cast err to type any because it would raise an error when I added the properties status and statusCode to err since type Error doesn't include these two properties. I am not sure if this is a good practice because I know it is not recommanded to declare or cast a variable to any, which actually is against the purpose of TypeScipt.
Are there any better solutions to it?

Configure and Display a Schedule of Opening Hours in PHP

---



Opening Hours is a PHP package by Spatie to query and format a set of business operating hours. You can use it to present the times per day and include exceptions for things like holidays and other days off on a given year-specific date or recurring (happening each year). The project's readme file has this example to illustrate how you can configure hours:
$openingHours = OpeningHours::create([
'monday' => ['09:00-12:00', '13:00-18:00'],
'tuesday' => ['09:00-12:00', '13:00-18:00'],
'wednesday' => ['09:00-12:00'],
'thursday' => ['09:00-12:00', '13:00-18:00'],
'friday' => ['09:00-12:00', '13:00-20:00'],
'saturday' => ['09:00-12:00', '13:00-16:00'],
'sunday' => [],
'exceptions' => [
'2016-11-11' => ['09:00-12:00'],
'2016-12-25' => [],
'01-01' => [], // Recurring on each 1st of January
'12-25' => ['09:00-12:00'], // Recurring on each 25th of December
],
]);

// This will allow you to display things like:

$now = new DateTime('now');
$range = $openingHours->currentOpenRange($now);

if ($range) {
echo "It's open since ".$range->start()."\n";
echo "It will close at ".$range->end()."\n";
} else {
echo "It's closed since ".$openingHours->previousClose($now)->format('l H:i')."\n";
echo "It will re-open at ".$openingHours->nextOpen($now)->format('l H:i')."\n";
}




This package has tons of configuration options and can be used on any PHP project without any dependencies. While this package isn't a brand-new Spatie package, we've never covered it and think you should check it out! You can get setup instructions and see more API examples on GitHub at spatie/opening-hours.


If you'd like to learn more background information on why this package as created, Freek Van der Herten originally wrote about it on his blog: Managing opening hours with PHP.

searching a list in a list model in flutter

I have been working on a LLM-like very simple project in Flutter. I need to find a string list, for example "what is my lecture score" in a list data. But the order doesn't matter.
If my search finds the "what", "is", "my", "lecture", "score" in one of the sentence list in any order, the result will be true, otherwise false.


Here is my sentence list as a List:
class vaModel {
final int id;
final List stringData;
final String response;

vaModel({
required this.id,
required this.stringData,
required this.response,
});
}



and here is the data of this model:
import "package:flut2deneme/pages/vaModel.dart";

List vaData = [
vaModel(id: 1, stringData: ["what", "my", "score", "lecture"], response: "load1"),
vaModel(id: 2, stringData: ["total", "lectures", "hours", "week"], response: "load2"),
vaModel(id: 3, stringData: ["how", "much", "cost"], response: "load3"),
//other
];



for example, if the user enters "what my score is for this lecture", it will return "load1" in id:1 in the vaData list. Because however the order is different and it has more other words, the desired words (what, my, score, lecture) are found in the data list. As seen, there are other words in the received sentence and the words are not in given order, the result is true, since all required words exist in item 1 (id:1)


It may also be explained in searching a list in a list of List.


Thank you for any support.

Laravel 10.26 Released

---



This week, the Laravel team released v10.26 with a search feature for the Artisan vendor:publish command, array cache expiry updates, more.


This week was a smaller release, but we get an excellent vendor:publish update that makes finding providers and tags a breeze! Laravel also saw some fixes and a few reverts leading us to Laravel 10.26.2. Thanks again for all the contributions from the Laravel team and the community!


Allow Searching on the vendor:publish prompt




Jess Archer contributed filtering the vendor:publish command to quickly search for providers and tags that you would like to publish. You can also select all providers and tags from the dropdown:





Ensure array cache considers milliseconds




In Laravel 10.25, Tim MacDonald contributed an update to ensure that array cache driver values expire at the expiry time; however, there were some testing issues around this update (which was reverted) and now in larval 10.26, those issues are all sorted. We would encourage you to update to the latest Laravel 10.26 version if you noticed any array cache driver flakiness, and thank you to Tim MacDonald for sorting it all out!


See Pull Request #48573 if you're interested in the updates made around that driver to ensure it honors expiry time.

Why I choose Inertia over Livewire

Hi, back when Livewire was first announced I gave it a try. I was excited, but I felt like the way it's hydrated doesn't fulfill my needs. Then I found Inertia and got excited again. Even tho it doesn't allow me to use Laravel's helpers I feel like I have full control and that's what I need.

Now that Livewire v3 came about, it looks much better and I had to try it again, to see if I could use it for my future projects. Wire:navigate is so amazing, but I just tested the very thing that made me leave the first time.

If it's a skill issue on my part, well, I'm a fool, will eat my critique and be happy that I was using Livewire wrong and can start using it properly now.

Let me demonstrate:

Model: class File extends Model { protected $appends = ['rand']; protected $fillable = ['name']; public function getRandAttribute() { return rand(1, 100); } }

Livewire Component: class Test extends Component { public $count = 1; // public $files = []; public function mount() { // $this->files = File::all(); } public function do() { $this->count++; } public function render() { return view('livewire.test')->with([ 'files' => File::all(), ]); } }

Livewire Blade: {{ $count }} @foreach ($files as $file) {{ $file->name }} {{ $file->rand }} @endforeach

I tested both commented and `with()` options, but both had same result. On every click, which only increases the count, the `rand` value changed.

Now you might see what's my problem. If the rand attribute was s3 file getter, I'm paying for every rerender.


https://i.redd.it/46gzkg08t5sb1.gif

So, is this doable in Livewire with different approach, or does it have to be like this? submitted by /u/narrei
