One of the best things Microsoft did was add Copilot/ChatGPT, Gemini and Claude to Github.

Google removing the "photoslibrary.readonly" scope from the Google Photos API was one of the worst things for anyone working with the feature.

@estevez Tks!! I was a little disappointed with Serverpod after seeing some benchmarks. 😅

Benchmark:
Axum (Rust): ~150.000 requests by seconds, between 10-50 MB RAM, 50.000 connections concurrent
Swoole (PHP): ~30.000 requests by seconds, between 100-300 MB RAM, 10.000 connections concurrent
NodeJS: ~20.000 requests by seconds, between 200-500 MB RAM, 10.000 connections concurrent
Go-Chi: ~70.000 requests by seconds, between 50-150 MB RAM, 30.000 connections concurrent
Serverpod (Dart): ~10.000 requests by seconds, between 300-500 MB RAM, 5.000 connections concurrent
Symfony (PHP): ~600 requests by seconds, between 300-1024 MB RAM, limited by worker

@fuzzybinary tks! I think Go will be better for automations: CSV, image and video processing.

Some people also recommended React Native for mobile apps and ElectronJS for desktop.

Is it worth learning Dart and, later, Flutter to create mobile and desktop apps and, occasionally, create CLI automations?

I'm not sure whether to learn Dart or GoLang.

The FuelPHP is one of the best PHP frameworks I've ever worked with. I miss it.

@Aron "the people that you write bdd tests for are just not interested in your tests."

I think this is really the problem. I am a front-end and in my opinion I think BDD tests make it easier to integrate between teams (Dev, QA, Product Owner and other members).

@Crell I agree that it is more work. But I think it facilitates integration between teams, especially in front-end testing (e2e)

Why haven't most developers adopted BDD (Behavior-Driven Development) for their tests?

Por que a Polícia Federal conseguiu recuperar o vídeo 'deletado' do Mauro CID?

Entenda como dados apagados em SSDs podem ser recuperados, o papel do comando TRIM, criptografia e técnicas forenses usadas em investigações digitais.

Pensei em usar builders (link), scopes do próprio Laravel ou até mesmo pipelines com filtros, mas acho que pode ficar bastante poluído o código

Enfim, sugestões?
