Go 1.25 Release Notes
The latest Go release, version 1.25, arrives in August 2025 , six months after Go 1.24 . Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before.

Writing simple tab-completions for Bash and Zsh
Shell tab-completions can be very handy, but setting them up is complicated by the fact that half your users would be using Bash-on-Linux, while the other half will be using Zsh-on-OSX, each of which has different tab-completion APIs. Furthermore, most users exploring an unfamiliar CLI tool using tab completion…

How attention sinks keep language models stable
We discovered why language models catastrophically fail on long conversations: when old tokens are removed to save memory, models produce complete gibberish. We found models dump massive attention onto the first few tokens as "attention sinks"—places to park unused attention since softmax requires weights to sum to 1…

6 weeks of Claude Code
It is wild to think that it has been only a handful of weeks. Claude Code has considerably changed my relationship to writing and maintaining code at scale. I still write code at the same level of quality, but I feel like I have a new freedom of expression which is hard to fully articulate. Claude Code has decoupled…
