protip: remember to ALWAYS beg the stochastic machine that it should ABSOLUTELY FOR NO REASON EVER forget to do the thing; there is still a nonzero chance that the stochastic machine WON’T do the thing, but you will feel much better about yourself

Major breakthrough tonight! After several back-and-forth weeks getting the Prism Ruby parser hooked up to the Chicory WASM runtime (AOT compiled to JVM bytecode), I now have a local version of the gem that uses *zero* native libraries. This will allow Prism to work anywhere JRuby does!

The future of social media is human We cannot continue participating in social media platforms which do nothing to stop us being tricked by GenAI and the powerful people/governments that control them.

I’ve been working on something for a while now and I wanted to explain how I got there.

you think you want AGI, but the agent swarm MUST be a swarm of junior devs to be effective; the senior dev would just tell you “I ain't doing that shit, that’s dumb”

so we really are accelerating 100x because I thought it would take them weeks, instead in the last 3 days people have realized that their “enhanced productivity” really is burnout-speedrunning

Humans, notoriously bad at multi-tasking:

“AI makes me so productive: I can do 100x more things in the same time I used to do just one! It’s so exhausting! I’m mentally drained at the end of my day!”

That’s nice, have you thought of just doing the one thing in 1/100th the time?

Right, but I'm thinking the chat UI is actually a cell, and commands would run in cells too

Claude Code, but the UI is a Jupyter Notebook. Has someone already built this? 🤔
