I need to apologize. This post was completely unfair. In order to coordinate a mob the IPv6 people would have to connect to each other somehow

Being highly online and exposed to diverse information streams used to help with creative thinking. Now being online makes you more average and incapable of original thought. Some people have realized this but a lot still haven't.

i'm in the trenches. i'm at war. i'm in the arena. i'm an operator. i'm a killer. i move mountains. we're winning. we're revitalizing. we're reindustrializing. we're the shield of western civilization - guy doing LLMs for procurement

The explicit move semantics is such a nice thing in Rust that I miss whenever I have to work in other languages again

WebSerial is a great addition for device-flashing from browser 🚀

Hold on, there’s a Tailscale client for ESP32 now? Why does nobody tell me these things?

@rustrover.jetbrains.com adding nextest support was great! any chance you have support for rstest test cases on the roadmap? VSCode/Zed have had this since forever and my coworkers are making fun of me

Just burned a couple hours debugging a handheld Pi project, seeing HAT not getting power. Then got out my probe and ran continuity test. "hmm that's weird, why are all of these holes sharing a node..." I ordered stripboard instead of perfboard 🤦

whoops

Friendship with Shapr3D ended, Fusion360 is new best friend

We've been working on a major schema migration at @polarsignals.com that has unlocked some pretty wild improvements. Apart from a 50% (!!) reduction in storage size thanks to logical compression in vortex.dev, there has been a dramatic improvement in query performance.

Best time of year 🌅

Fun 30 minute 3D print project: diffuser that fits on top of cheap target lamp

the future is here

You can in fact just do things

billionaire being interviewed: i havent listened to a single note of music in 27 years. think about it, music was basically invented, what, maybe 50 years ago? interviewer: this is really interesting

To be extra realistic, there is no data for the month of August

It's still hilarious that when I ask Claude to draft up a plan for a complex task, it gives me human-time estimates. "Part 1: Months 1-3. Part 2: Months 4-6" But then you just tell it to go and it finishes everything in a few minutes lol

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

"at least for now"

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

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

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

RUST REFLECTION MVP HAS LANDED github.com/rust-lang/ru... THIS IS NOT A DRILL

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. Doc: abseil.io/fast/hints.h...

CommonForms is cool. Guy filtered CommonCrawl down to PDFs and trained a 3-class YOLO model on it. Performs better than Acrobat. arxiv.org/pdf/2509.16506

TIL ClickHouse is able to optimize queries using information from table constraints, pretty cool! clickhouse.com/blog/whats-n...

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. Thread 1/n

Sneakers deserves a mention as well. RIP to a legend.

Crazy shit happening in the footnotes of this ruling

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. foursquare.com/products/spa...

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

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.
