I’ve been working with Claude Code since it was released and have developed a workflow that lets me safely manage multiple streams of work in parallel. This is a deep dive into how it works. At a high level, I: - Parallelize my work streams through extensive use of git worktrees…

Vibe coding is irresponsibly building software through dice rolls, not caring what code is produced What about when engineers at the top of their game use AI tools responsibly to accelerate their work? I propose "vibe engineering"!


I’m enraged by Charlie Kirk’s assassination. Especially so soon after the murder of Iryna Zarutska. As a father of two little girls, having watched both of these videos, it all hits too close to home. I want to squad up, fight back, pick fights, DO SOMETHING to vent that rage.…


100% This

Dear lefties: One of yours just killed Charlie Kirk. What you don't understand is that Charlie was a sweetheart compared to the people who are likely to gain power from the hatred you have sown with his death. No, I don't know who those people are. And I don't expect to like…

Btw, since people don’t seem to know this, you can literally spawn subagents in Claude Code just by asking.

We've reached a major milestone in fully decentralized training: for the first time, we've demonstrated that a large language model can be split and trained across consumer devices connected over the internet - with no loss in speed or performance.

Great post from @tqbf at @flydotio: but you have no idea what the code is Are you a vibe coding Youtuber? Can you not read code? If so: astute point. Otherwise: what the fuck is wrong with you? (link below)

fix the teachers, the grades, the curriculum, teach more practical skills, and let them use AI, and people won't cheat. but after you've done all that, what is left of universities? very possibly, nothing, and THAT's the real reason educators are freaking out


Does pressing K and J move up and down the timeline for anyone else? Apparently GG goes straight to Grok. Cool.


Congratulations! Huge achievement.

Release 410k is now live across the network! This major release delivers the long-anticipated Directed Messaging upgrade for faster, more reliable networking, plus: • Double boot protection • Essential desks • Lagoon (native matrix math) • HTTP streaming • Memory usage…

The idea here is mainly that there exist other models that appear to be smarter than 3.7 Sonnet at this point, but Claude Code + Sonnet (necessarily) is better at banging out the implementation than other tools. x.com/tryfoundergg/s…
