Since archiving my #RECaptcha package, i haven't receive one single complaint after #Google made it paywalled.
Since then, my #Turnstile package has been downloaded 1,000 times, 89 times less than the aforementioned.
I wonder if downloads will spike on Laravel 13, since there will be no support for it when it lands next february.

After sharing a tip on how I worked around a quirk with MySQL default values in my tests, several people suggested a better approach using Laravel default attribute values. This was a really nice improvement! #php #laravel https://masteringlaravel.io/daily/2025-09-01-using-eloquent-default-attribute-values-instead-of-mysql-default-values

🎯 #StateMachine Pattern in #PHP: Transform Complex Workflows Into Clean, Predictable Code
⚡ Replace tangled if/else statements with explicit states, events & transition rules for order processing, article workflows & business logic
🔒 Built-in safety: Forbidden transitions (like refund before payment) are blocked by design
🧪 Pure, testable logic: Guards decide transitions, actions handle side effects after state changes

Ran the benchmark no was waiting for today: all the different ways to list all files in a local directory in PHP.
- A lot of time is spent on sorting, so providing flags for no sorting is an easy perf win
- scandir with SCANDIR_SORT_NONE is consistently fast
- Glob with sorting (the default) is consistently slow (2x scandir without sort)
- DirectoryIterator is slow for directories with less than 1000 files, but then starts gaining and becomes as fast as scandir at approx. 10000 files

🌐 Novo no blog: Distância entre Dois Pontos na Esfera
Apresento métodos para calcular distâncias entre dois pontos na superfície da Terra usando latitudes e longitudes. Explico a fórmula de Haversine (mais simples e rápida) e comparo com Vincenty, que é mais precisa para elipsoides. Mostro também um exemplo em PHP e referências para aprofundar. Confira: https://danieltak.com.br/posts/algorithms/distancia-dois-pontos-esfera/
