ZigSoftware Zig Software Foundation

Zig is exceptional software: ambitious, practical, independent, and unusually serious about quality. Ghostty exists in large part because Zig made it possible for me to build the kind of software I wanted to build. This is why I support Zig.

I use Vagrant with VMware Fusion, because Fusion is just better than VirtualBox. Fact.

I have no problem with what Bun did, I think Bun is a great project, and I'm not interested in turning this into a Bun post.

The command palette that ships for macOS in Ghostty today is only very lightly modified from what Gemini produced for me in seconds.

AmpSoftware Sourcegraph

I particularly like to combine this with slower, more thoughtful models like Amp's deep mode (which is basically just GPT-5.2-Codex) which can take upwards of 30+ minutes to make small changes. The flip side of that is that it does tend to produce very good results.
