Last year I released the container image I use to compile @CrystalLanguage apps. You can use it to build and test against different version, 1.2, 1.3 or latest 1.5.1 This started a series of experiments on things I'm working on since then... 1/ 🧵

Decided to make public my Alpine-based, Crystal development container image: hydrofoil-crystal github.com/luislavena/hyd… Quick demo of Radix library using it to automatically run specs on changes. Have fun! @CrystalLanguage #crystallang

Sometimes Claude (Opus/Fable) wants me to read its mind: Claude Code: do you approve with this approach? (shows nothing for me to approve) Me: no, show me the plan *thinks* Claude Code: There, do you approve this approach? (there is nothing again in the output) 🙃

"Uncloud Hub is for the day you'd rather ship features than manage and monitor the monitoring stack." Suffered this exact pain more times than I can count. My cluster, my data + reliable monitoring. This is the right balance I have been waiting for.

I'm starting to build the next chapter of Uncloud: Uncloud Hub 🌐 Uncloud made deploying on your own servers easy. But production only really starts when the deploy finishes. Hub is the missing dashboard and observability stack for your clusters so you can see what’s happening

I built an agent skill whose main job is to talk me out of building things. Yup, no more "great idea, here's the architecture." It demands evidence first, and only writes requirements if the idea survives. New video on YouTube:
