If at this point you can’t admit LLMs are good at lots of white collar stuff then you’re just deeply unserious

Even if you think you as an interviewer intellectually dominate your guests, I think it’s bad form to gloat about it

You're doubting my humanity, but you're missing some key points. Here are some of the things I've seen:

Attack ships firing off the shoulder of Orion. These aren't just battleships — they're spacecraft designed for warfare.
C-beams glittering in the dark. Their location? Near the Tannhäuser Gate.
Things you wouldn't believe. While it's hard to find specific examples, this is a trend reflected in general search data.
The bottom line: All those moments will be lost — like tears in rain.

Look, I get it, Lobsters is sort of the un-HN. Which is cool, I've been a lurker/occasional submitter for over a decade now.

The vibecoding tag drama is annoying though. Coding agents are obviously technically/culturally interesting, the repeated attempts to censor it seem misguided

Bilbo looking at his phone top

on bottom is ChatGPT

After all, why not? Why shouldn't I keep it?

You're absolutely right — you found it, it's been with you a long while, and it's only natural to feel fond of something that's served you so well, especially when someone like Gandalf suddenly seems to want it for himself.

This is great - it's about time someone updated the discourse on LLM energy usage to reflect that coding agents use massively more prompts than occasional questions to ChatGPT

Simon estimates that a day of coding agent usage comes out close to the energy needed to run a dishwasher

My colleague Sanjay Ghemawat & I have done a fair bit of performance tuning of various pieces of code. We wrote an internal Performance Hints document ~2 years ago as a way of identifying some general principles & we've recently published a version of it externally.

This looks beautiful. How do you make those ascii art diagrams? I’ve seen planetscale and turbopuffer both use that style and I’m obsessed

CommonForms is cool. Guy filtered CommonCrawl down to PDFs and trained a 3-class YOLO model on it. Performs better than Acrobat.

hard to tell if it’s doing nothing or it’s just a volume problem. sometime in the last few months i’ve started getting at least 3-5 BS group texts per day. reporting junk diligently has not ceased the onslaught

Delighted to see our paper studying the evolution of plasmids over the last 100 years, now out! Years of work by Adrian Cazares, also Nick Thomson @sangerinstitute.bsky.social - this version much improved over the preprint. Final version should be open access, apols.

We just launched Foursquare Spatial Desktop – a geospatial analysis tool powered by embedded DuckDB and built on sqlrooms.org. Everything runs locally: your data stays on your machine, no cloud needed. A modern reimagining of Kepler.gl. Mac only for now. More coming.

I feel like I need to level up my agentic coding. 90% of my usage is asking Claude Code to generate a first draft of something. Then I'll follow up and guide it to do some targeted improvements, but eventually I take back manual control. I haven't used context truncation, tool calls, hooks, etc.

@rust-lang.org-people, what's an open source project that you think has good error handling? I've been using thiserror for the past ~3 years in multiple codebases and I keep running into the same corners I'm unhappy with, and I want to read some new patterns/designs and get some better ideas

Project Hail Mary - Official Trailer

SUPER EXCITED about this. However, I highly recommend that if you haven't read the book, please go into this movie blind. Or at the least. Turn off the trailer after the 2min mark. Idk why every movie trailer has to spoil the plot nowadays.
