bpftop has a new home. The repo now lives on my personal GitHub account, and v0.8.0 is out as the first release from there.

All existing links redirect, but if you're a distro packager, now's a good time to update your source URLs.

Auto mode is the one feature you should be using. Pair it with /goal and you can step away on a tough problem and come back to a ton done.

People often ask what my biggest tip is for getting the most out of Claude Code.

These days my #1 tip is: use auto mode

Auto mode means no more permission prompts. It is the key building block for multi-clauding: start a session, then while it runs, work on another session in parallel.

Weekend project: use Claude to migrate my Linux gaming rig from Bazzite to NixOS. Then all my home infra will be in a central monorepo.

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

Claude Security is now in public beta for Claude Enterprise customers.

Claude scans your codebase for vulnerabilities, validates each finding to cut false positives, and suggests patches you can review and approve.

Over the past month, some of you reported Claude Code's quality had slipped. We investigated, and published a post-mortem on the three issues we found.

All are fixed in v2.1.116+ and we’ve reset usage limits for all subscribers.

@FrameworkPuter wen 16 pro?

[Jose Fernandez @jrfernandez]

Fighting back the urge to impulse buy this. If they release a 16” version then it will be an instant buy.
