I’m reshaping this account around the OSS/dev tooling work I care about most I’ll be sharing reproducible workstations, AI-native developer workflows, app scaffolding, DevEx, persistent context for coding agents, and V scientific tooling Most of it already lives on my GitHub

🚀 Ulises Jeremias migrated agent-toolkit's canonical CLI from Python to V. The goal: make the binary native, fast, portable, and easy to distribute. Linux startup: `--version` 43ms → 4.7ms inventory 164ms → 8.6ms doctor 735ms → 5.6ms github.com/ulises-jeremias/a…

The V Programming Language@v_languageAug 16
Recently, 12 new V bugs were reported on GitHub. None of them could be reproduced with the new compiler. It simply doesn't have these bugs. That means the new architecture is more robust and better designed. The new compiler is becoming the default on macOS this week.

The V language tried an interesting experiment: what if you start with Go and add all the features the Go team left out to keep things simple? Enums, sum types, unions, pattern matching, attributes, access modifiers, operator overloading, named and default parameters — V has them all. There's even a built-in ORM! 🫠

Bro said, "I'm a backend dev." Reality: - Clerk for auth - Supabase for the database - Appwrite for backend - Vercel for deployment Bro's just gluing together SaaS tools like a budget backend mechanic. That's not backend engineering That's API Lego with typescript

i never thought i'd say this, but coding got boring you write a prompt, wait 10-50 minutes, review the code, ask for fixes, then repeat that's it. that's the job now no more debugging for hours. no more stack overflow rabbit holes just… prompting. reviewing. prompting again

"Users don't care about performance" They do. They just rarely have a choice. Give them to choose between a slow and a fast app and you will be blown away by the results. The problem is that all apps these days are a slow, buggy crap. It's you who don't care. Not them.
