More AI-generated code doesn't make your team faster. It might actually slow you down.

@evanyou @voidzerodev Congrats!!! Great pairing

[Cal Lavicka @CalLavicka]

@FredKSchott @tannerlinsley crazy impressive!

@RhysSullivan Using AsyncLocalStorage, AbortSignals, and promise helpers has been pretty good, and keeps my code compatible with most libraries and LLM code out-of-the-box, but very tempted to switch to effect...

Been burned before by backend API lock-in is why I'm hesitant.

We just moved into our first office in the Mission. My only requirements were that it be a single-story building and formerly a garage

Can a language model learn, end-to-end, what to keep in its own KV cache and what to throw away? Can it learn to forget while it learns to reason?

Deep learning's central lesson: capability emerges from end-to-end optimization, not heuristics/strong inductive biases. But for efficiency, we rely heavily on hand-designed approaches.

🗑️ Introducing Neural Garbage Collection (NGC): we train a language model to jointly reason and manage its own KV cache, using reinforcement learning with outcome-based task reward alone. No SFT, no proxy objectives, no summarization in natural language.

New paper with @jubayer_hamid, Emily Fox, and @noahdgoodman!

idk aws, should I use the "enhanced" builder, or the "advanced" one? tough choices...

[Cal Lavicka @CalLavicka]

@jacobmparis IIRC most thinking traces are passed through another LLM to make them less useful for distillation

@lukaivanovic @Lovable Congrats!

Welcome home Reid, Victor, Christina, and Jeremy! 🫶

The Artemis II astronauts have splashed down at 8:07pm ET (0007 UTC April 11), bringing their historic 10-day mission around the Moon to an end.

@badlogicgames Congrats, loved using libGDX back in the day and glad to hear that pi has a permanent home

We're hosting a happy hour for ~50 developers on Accel's rooftop tonight at 6:30 and have a few spots left. DM me to get added or RSVP at the link in the comments

"Strong preference for software that reduces chaos instead of adding more of it" everyone should strive for this

Products are built by humans, and I'm leaning into that.

Added a new section to the Solo homepage.

@aarondfrancis @dillon_mulroy It’s really revealing to me who actually cared about code quality before

[Kofi @0xKofi]

I've been seeing a lot of folk on the timeline say IDEs are dying. But I don't get it. Are you guys not reviewing the code your agents generate 😅

[Cal Lavicka @CalLavicka]

@dillon_mulroy I feel like i'm taking crazy pills. People are seriously merging this shit into production without looking at it?

[Cal Lavicka @CalLavicka]

@_developit People truly be saying coding is solved and yet we can't get basic focus management right

[Cal Lavicka @CalLavicka]

@mitsuhiko nah opus 5 will fix everything trust me just one more model

[Cal Lavicka @CalLavicka]

When you give every engineer a magic button, it separates the ones who truly care about the craft and the ones who were never going to succeed anyways

[Armin Ronacher ⇌ @mitsuhiko]

The biggest issue for me with agents is that they are hard to resist. But then you can build yourself some shit into the codebase that you get to regret in record time. And no, I don't think you can vibe yourself back to sanity with better models.
