Claude Code, Metals, and NVIM While skeptical at first, I've found in the past few months that I've landed on a flow developing Scala that I'm quite happy with that allows me to stay in my comfortable nvim/tmux/terminal environment while benefiting from assistance that still allows me to feel like I'm in control and boosts my productivity.

Minimal Scala Container Images using Nix I was able to reduce the container size from 722 MB to 198 MB. Thanks to Nix, creating a minimal image is really convenient because the build system does the most of the heavy lifting to figure out the necessary packages. Java also has very good tooling to create a minimal JRE, just enough for the application to run. I believe there is still room for improvement to reduce the size, but it is already good enough for my use case. Onur Sahin
