Automatically tie a UnityEngine.Profiling profiler sample to every method in a class

4 April 2026 @ 4:31 pm

When using UnityEngine.Profiling, we can sample parts of our code in order to understand how much time and space they take up whilst running, like so: using UnityEngine.Profiling; public class MyClass { void MyMethodA() { Profiler.BeginSample("MyClass.MyMethodA"); // Code here Profiler.EndSample(); } void MyMethodB() { Profiler.BeginSample("MyClass.MyMethodB"); // Code here Profiler.EndSample(); } void MyMethodC() { Profiler.BeginSample("MyClass.MyMethodC"); // Code here Profiler.EndSample(); } // ... and so on. } Here, in this class, I've aptly tied Profiler samples to each of my methods so that I can analyze them. Writing Profiler.BeginSample and Profiler.EndSample all the time gets a little tedious in my opinion, once we start to write lots

Why is Spring Boot still used in large-scale systems despite newer backend frameworks?

4 April 2026 @ 4:04 pm

I am learning backend development using Java and Spring Boot and have built REST APIs using it. I noticed that newer technologies like Node.js and Go are becoming popular for backend development. However, many enterprise applications still use Spring Boot. Can someone explain: What advantages Spring Boot provides over newer frameworks? In what scenarios is Spring Boot preferred in production systems? Are there specific features (like dependency injection, ecosystem, etc.) that make it suitable for large-scale applications? Looking for technical explanations or real-world examples.

python-semantic-release + Woodpecker CI: How to support RC builds and keep a grouped changelog for the final release?

4 April 2026 @ 3:19 pm

I’m struggling to design a correct CI/release workflow using python-semantic-release together with Woodpecker CI, and I feel like I’m mixing concepts incorrectly. My goals are: Accumulate multiple commits (feat/fix/chore/etc.) Have them appear under a single grouped version in the changelog (e.g. v2.1.0) Still be able to generate and use versioned RC builds (v2.1.0-rc.1, rc.2, etc.) for testing before release Maintain a clean and predictable CI/CD flow What I tried 1. dev + main with semantic-release on both Feature branches → squash merge into dev Run semantic-release on dev → generates vX.Y.Z-rc.N Then merge de

EMV mode stuck in infinite loop after 6283 warning during block card test case

4 April 2026 @ 2:14 pm

Apologies for the confusion. The test bench itself is not implemented in C; however, the card OS is implemented in C. The issue occurs during the EMV transaction processing on the card side. I can share relevant logs/APDU traces if that would help in diagnosing the problem.

Get a value of non-default-constructible type `T` from a byte array without undefined behavior

4 April 2026 @ 2:02 pm

I'm messing with FFI between Rust and C++ and I happen to know that some particular array of bytes pointed by a std::byte * pointer is a valid C++ object of type T, which can be anything for what concerns this question. How do I get back a valid value of type T from this array of bytes? What does not work: reinterpret_cast does not work because of the strict aliasing rules, apparently: template<typename T> T transmute(std::byte *ptr) { return *reinterpret_cast<T *>(ptr); // UB } memcpy works but requires T to be default constructible. template<typename T> T transmute(std::byte *ptr) { T value; // requires a default constructor memcpy(&value, ptr, sizeof(T)); return value; } the latter is usually suggested (also on the

Why should I learn Javascript if I could just learn jQuery?

4 April 2026 @ 1:31 pm

I'm a beginner web developer, and I'm mostly working on a personal website of mine. I'm trying to learn the basic stuff since I'm still in school and don't have much time to learn additional languages. right now, I'm focused on HTML and CSS. I want to begin making my site dynamic, but I'm not sure whether I should learn Javascript or jQuery. some people say jQuery can conflict with existing frameworks, that it's outdated, while some others say it simplifies Javascript. I tried learning Javascript but unfortunately found it too hard. some people say to learn Angular or React or Vue, and I can't find a solid answer.

VS Code Intelephense shows "Undefined method" on custom Eloquent relationship after Auth::user()

4 April 2026 @ 12:00 pm

Problem Description I am using Laravel 13 and Visual Studio Code with the PHP Intelephense extension. I have defined a HasMany relationship in my User model called task(). However, when I try to call this method via the Auth facade, my IDE marks it as an undefined method. If I try to change the syntax, the error often shifts to the user() method itself. My Code App\Models\User.php: namespace App\Models; use Illuminate\Database\Eloquent\Relations\HasMany; use Illuminate\Foundation\Auth\User as Authenticatable; // ... other imports #[Fillable(['name', 'email', 'password'])] class User extends Authenticatable { // ... factory and casts public function task(): HasMany { return $this->hasMany(Task::class); } } Livewire/TaskList.php /
