@Hasen_Judi Docker is why I went to Nix. Nix = actually-reproducible declarative deterministic dev and build environments Docker = a space-wasting lucky cache of an imperative accidentally-correct nondeterministic build

@eiselems Claude has been running my nanochat experiments since morning. It writes implementations, debugs them with toy examples, writes tests and makes them fail/pass, launches training runs, babysits them by tailing logs and pulling stats from wandb, keeps a running markdown file of

I was writing some code the new-school way yesterday, prompting gpt-4.1 through aider, and for whatever reason my mind flashed back 50 years and the utter freaking enormity of it all crashed in on me like a tidal wave. And now I want to make you feel that, too. In 1975 I ran

This does feel like the ground moving under our feet, because it is. What used to be a mostly closed system (code, specs, tests, deploy) now has a live, probabilistic co-processor bolted onto it, and we’re all learning how to think with it at the same time. No manual, no stable
I've never felt this much behind as a programmer. The profession is being dramatically refactored as the bits contributed by the programmer are increasingly sparse and between. I have a sense that I could be 10X more powerful if I just properly string together what has become

@RBReich What’s missing from this entire framing is harm. You don’t name any victim, any fraud, any coercion, any theft. Just a big number next to a smaller one to trigger envy. Voluntary contracts approved by shareholders aren’t theft. Wealth created through innovation and trade isn’t

This rings true to my experience in AI art. Experienced artists are curious and want to learn more - they see it as a useful tool to express their ideas. Haters are typically amateurs who don't like that people using AI now have the skills they had to spend time learning.
amateur artists are way more anti-ai than professional artists

I think it’s an apt analogy because it both weakens you and makes you go faster while leaving you in control, so overall you are still far more effective/productive

Steve Jobs said computers are a "bicycle for the mind." As I work here with the latest AI tech on code, I'm coming to believe that this generation of AI will end up being a "motorcycle for the mind". https://t.co/XHm3oO4iZK

Prevent yourself from getting burned by `rm -rf`/`sudo rm -rf` style mistakes by diverting those files to the Trash instead. - pmarreck/rm-safe
@radshaan It’s probably time to move it into its own project, but I have this script here in my dotfiles that I made, `rm-safe`, which will more safely execute `rm` by moving things to the Trash on both Linux and macOS while also adding to a logfile that logs what was moved from where.

What’s the correct response to this?
A US teacher sharing her classroom experience. One of the comments underneath says: "47 years teaching. Just retired this year. The difference between then and now is like night and day. The kids have zero attention span!"

Is talking to an AI, about AI, an implicit epistemic closure?

In a new proof-of-concept study, we’ve trained a GPT-5 Thinking variant to admit whether the model followed instructions. This “confessions” method surfaces hidden failures—guessing, shortcuts, rule-breaking—even when the final answer looks correct. https://t.co/4vgG9wS3SE

We’re sharing an early, proof-of-concept method that trains models to report when they break instructions or take unintended shortcuts.

How do you know something is written in Rust? Don't worry, they'll tell you.
