Has anyone used Turbolinks + Laravel to create a native hybrid app?

I really want a simple iOS app for my Laravel project, but I’m not seeing very many recent posts / tutorials/ etc about Turbolinks and Laravel.

Has Turbolinks pretty much become exclusive to Ruby on Rails? Anyone know of alternatives or have RECENT tutorials on using it with Laravel?

Thanks 🙏 submitted by /u/LikeAnElephant

My "Model Required Fields" package

With Model Required Fields package, you can get the required model fields, excluding primary keys, nullable fields, and fields with defaults.

I first needed this information while working on a large project with no tests or factories and many migrations. It was distracting to manually look for each required field.

I created a simple trait to fetch required fields. It was easy in Laravel 11 and 10. Then I realized that most programmers who face this problem are usually using older versions, so I added support for Laravel 9, 8, 7, and 6, and extracted the logic into a package.

I tested the code for each supported Laravel version and each SQL database: SQLite, MySQL, MariaDB, PostgreSQL, and Microsoft SQL Server. I needed to add support for each SQL database because I used the DB facade with raw SQL queries, and there were slight differences each time.

The package is fully tested with PHPUnit and GitHub Actions for every Laravel version and for each database.

The usage and examples are in the readme file.

I hope you like this package, and I welcome any contributions or comments.

How to find ceritain value in multiple section and return other value

How should I write this formula


Find the Square section where Value A at (Gary is in 8 in this case), and get the name " Ocho" from list underneath


then find where is Value B, Put Ocho at highlight place in value B section


Then list the rest clockwise

OpenCV - How to compute 3D points with SfM methods with known fundamental matrix

For a university project, we are working on implementing a basic SfM pipeline, using Middlebury's "temple" dataset. This means that, for each image, the projection matrix for that given image is known. I have done some reading and seen some examples on SfM reconstruction, where, usually, the camera rotation and translation are unknown and PnP algorithms are used to obtain them.
My question is, given we know the projection matrix for any given image, what would the processing pipeline look like? I envision something along the lines of:



* Compute SIFT keypoints and descriptors for each image.

* Pair "adjacent" images (in this case, images with sequential ids from the dataset)

* Find point matches for each pair using KNN or similar matching algorithm.

* Use cv2.triangulatePoints to find the corresponding 3D point for each of the 2d point matches using the known projection matrices.






I understand that, generally, the most difficult aspect of SfM is precisely the step we are skipping over of pose estimation. However, for now we are only aiming for a basic implementation, possibly implementing a "complete" algorithm that includes this step later.


Still, I am unsure as to whether there are any processing steps that would be necessary in order to obtain "good" results.



* Would something like undistortPoints be necessary for this estimation?

* What would be the most efficient way of building the point cloud (for example, building feature tracks and only include points that result from the triangulation of some number of images n)?

* Finally, where and how should we discard pair outliers? Most of the functions offered by OpenCV use RANSAC as part of the pose estimation process, and I don't know if there are functions that would allow us to use the algorithm in our case (if it would even be necessary).






So far, we have implemented a basic SIFT keypoint extractor.
Unsure where to continue from here.

How to resolve a Cors error when trying to get an authentication token using authorisation code grant in Next.js

I have an app where im trying to send a generated pdf to get a signature. Pretty straightforward.
I got the authentication working in postman, but when I try it in code, I get this error:


Access to fetch at '
https://account-d.docusign.com/oauth/token' from origin '
http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.


I can retrieve the oauth code with this:
if (router.asPath !== router.route) {
setOAuthCode(new URLSearchParams(window.location.search).get("code"));
}



but in a seperate use effect, i try to submit this oAuth code, it falls appart:
useEffect(() => {
const getAuthToken = async () => {

const tokenUrl = "
https://account-d.docusign.com/oauth/token"; /> const encodedSecret = btoa(
`${process.env.NEXT_PUBLIC_DOCUSIGN_INTEGRATION_KEY}:${process.env.NEXT_PUBLIC_DOCUSIGN_CLIENT_SECRET}`
);

const headers = {
"Authorization": `Basic ${encodedSecret}`,
"Content-Type": "application/x-www-form-urlencoded",
};
const body = new URLSearchParams({
grant_type: "authorization_code",
code: oAuthCode,
});

const response = await fetch(tokenUrl, {
method: "POST",
headers: headers,
body: body,
});

if (!response.ok) {
throw new Error(
`Failed to get access token: ${response.status} ${response.statusText}`
);
}
const data = await response.json();
setAuthToken(data.access_token);
};
getAuthToken();
}, [oAuthCode]);

.Net 8 XUnit: Use an In-Memory DBConnection for testing as a replacement for the real MySqlConnection

I'm creating tests for my .Net 8 API, and as I want to test with fake self created data (instead of using the real MySql connection) I'm having problems figuring out how to implement that behavior, I mean, using -for example- an In-Memory database.


We use CQRS (Mediator pattern) for the database queries, and on each query handler we inject ICloudStackCoreConnectionFactory which includes (among others) a CreateConnection method that returns a DBConnection (in our case, a MySqlConnection):


ICloudStackCoreConnectionFactory:
public DbConnection CreateConnection(Region region)
{
return (DbConnection)new MySqlConnection(GetConnString(region));
}



I'd like to replace that MySqlConnection implementation by an in-memory connection so I can test with a reduced set of fake data, but I don't know how to do it.


We use a "Lab" to create all stuff needed for the tests, and the Lab includes a create method as follows:
public static Lab Create(ITestOutputHelper output)
{
var appFactory = Vdc.Libs.AspNet.Testing.Setup.Factory(
out var client,
out var authorize,
out var identity,
out var faker,
role: $"{VdcSecurity.Role.Management},{VdcSecurity.Role.ManagementAdmin}",
output: output,
setup: services =>
{
}
);
return new Lab(identity, appFactory, client, authorize, faker);
}



I know I could use Mock library to mock the ICloudStackCoreConnectionFactory interface, but as I debug, when the test starts the real "Program.cs" is launched, so is clear we are using the real hosted services and so I don't know how to replace only that interface with the mocked one.


Then I also don't know how to return a DBConnection In-Memory database with data in the "CreateConnection" method.


Any help?

Pass multiple arguments to single command in custom position xargs

I want execute a command where I have the args as single string but they need to be in a custom position. E.g. in the following example I want the args to be positioned before any fixed args that I have written after the cp comamnd i.e. the path argument /somedir


I want:
echo -n 'file1 file2 file3' | xargs -d ' ' -I{} cp {} /somedir



to behave like:
cp file1 file2 file3 /somedir



but it doesn't...


It also looks like when including the -I{} option, the -d option makes xargs behave differently. It seems like it tries to pass each argument to a separate command call rather than all of them toa single one.


For example, this works:
echo -n 'file1 file2' | xargs -d' ' diff



But this fails
echo -n 'file1 file2' | xargs -d' ' -I{} diff {}



With error:
diff: missing operand after 'file1'
diff: Try 'diff --help' for more information.
diff: missing operand after 'file2'
diff: Try 'diff --help' for more information.



How can I get echo -n 'file1 file2 file3' | xargs -d ' ' -I{} cp {} /somedir to behave as intended

Temporary block when using Credential Manager to Sign in with Google

I'm testing the 'Sign in with Google' flow with Credential Manager by following the indications in the official docs. So far, the process works as intended: it shows a bottom sheet with the available accounts and it allows me to sign in to the selected account.


However, I observed that if I dismiss the bottom sheet 4 times in a row, the bottom sheet doesn't appear anymore and I get the following exception:
androidx.credentials.exceptions.NoCredentialException: During begin sign in, failure response from one tap: 16: [28436] Caller has been temporarily blocked due to too many canceled sign-in prompts.



That exception seems to come from the old 'One Tap' flow. As explained in the One Tap docs, "If a user cancels several prompts in a row, the One Tap client will not prompt the user for the next 24 hours".


Which leads to my question:


If a user who is trying to sign in into my app dismisses the credential prompt 4 times in a row (which I can easily see happening), what should I do? Telling them that they cannot use the app for 24 hours seems a bit excessive. Is there any alternative?


NOTE:


It's important to point out that the old GoogleSignInClient didn't have this limitation.

Laravel Breeze with PrimeVue v4

This is an follow up to my previous post about a "starter kit" I created with Laravel and PrimeVue components.

The project has been updated with the following new changes:

* Upgraded to Laravel 11
* Updated to use Laravel Breeze backend instead of Fortify (for the potential to abstract this project as a fork of laravel/breeze with custom stubs)
* Upgraded PrimeVue to v4 (overhauled theming and light/dark mode)
* Removed PrimeFlex and re-added Tailwind CSS for utility styling




Feedback is welcomed as a GitHub issue or PR, thanks!

Is a back_insert_iterator valid for the lifetime of the container?

I think I know the answer to this, but I'd appreciate a sanity check.


Does iterator invalidation apply to std::back_insert_iterators?
#include
#include
#include

int main() {
auto v = std::vector{ 0, 1, 2 };
auto iter = std::back_inserter(v);
*iter++ = 3;
v.clear(); // invalidates iterators, but
*iter++ = 4; // back_insert_iterator is special?
assert(v.size() == 1 && v[0] == 4);
return 0;
}



This code works for me because the std::back_insert_iterator implementation from my vendor doesn't hold an iterator (or pointer or reference). It simply calls the container's push_back method.


But does the standard require that implementation? Could another vendor's back_insert_iterator hold and maintain a one-past-the-end iterator to use with a call to the container's insert method? It seems that would meet the requirements. This difference, of course, is that it would be vulnerable to invalidation.

---



I know cppreference.com is not authoritative, but it's more accessible than the standard.



[A vector's clear method] [i]nvalidates any ... iterators referring to contained elements. Any past-the-end iterators are also invalidated. [cppreference.com, emphasis added]



A std::back_insert_iterator could be the poster child of a past-the-end iterator.

sorting algorithm in O(n) according a specific condition

Given an array A with n−1 numbers where n = 2k
for some integer k. One of the values appears exactly n/2
another appears exactly n/4, and so on. More formally, for all 1 ≤ k ≤ log n exists a value that appears exactly n/2^k times in the array. Describe an algorithm that sorts A with a run time complexity of Θ(n), and analyze its running time.
example: input: 5,1,2,1,2,2,2
output: 1,1,2,2,2,2,5


some important pointers:
1.the time comlexity should be Worst case
2.using a dictionary is not allowed
3.the solution should use a stack or other basic data structures


i tried using counting sort but it didnt work because the array doesnt contain values starting from 0 and up.
i also thought about using a hash map but the wanred time complexity would be expected and not worst case.

What rector rules do you use?

I have been playing around with Rector to ensure a more consistent codebase and there are a lot of rules to choose from. Additionally there's even a Laravel Rector package with more rules to choose from on top of that.

I am using a few, such as the early return rules and moving the property to the constructor as I think they're niceties but I'm interested in what rules the wider community uses.

All the rules seem like such good ideas but I'm not sure if it is wise to use them all, even if the application is pretty well tested. submitted by /u/TertiaryOrbit

how can i find message window in Quartus

There are no messages window below the code blocks
I'm using Quartus eda tool for fpga jobs with verilog HDL.
For compiling, i need message window to know errors in my code blocks.
But i can't find message window that indicate errors below the code blocks.
I wanted to extend code blocks so i dragged with my mouse and reduced messages window.
I compiled my code blocks but no messages window appeared.
So, I tried to solve problems in two ways but it didn't worked.
First, I tried rebooting the program.
Next, i clicked the window bar but message window didn't appear.
Thanks for reading. Hopes for good answers.
