I'm enjoying using Claude Code, but... why does it use so much CPU time when surely it's essentially just blocked on I/O almost all the time? Is it just doing some really inefficient polling or something?

So excited to finally share what we've been building at CUE Labs! Proud to be on this mission with @mpvl.io, @myitcv.io, @rog.bsky.social, @hylomorphism.bsky.social, and @dominikdm.bsky.social.

Today, I'm proud to officially announce CUE Labs! I co-founded CUE Labs with @mpvl.io to build a Configuration Control Plane, solving config chaos with CUE. Our work also provides the stewardship for the @cuelang.org open source project. Read our launch post: cue.dev/blog/announc...

This heartfelt and meaningful statement by Portland resident and author Cristina Breshears on another social media platform bears reposting here. I don't think the intent is to idealize Portland but to remind all of us what is important and why. (Posted here with permission.)

Just been mostly-vibe coding a PoC. I feel a bit like I feel when I'm on a drag lift up a ski slope: very aware how much work is being done for me. And then I get to play on the downhill after each feature is built. Lots of fun!

Been playing around with @cuelang.org and building a new home automation system to control my lighting and written up first post about the project still loads of other content to write though! Big thanks to @myitcv.io @rog.bsky.social @mvdan.cc for all there help aran.dev/posts/cue/us...

TIL Claude's new code interpreter mode has a /mnt/skills/public/ folder full of prompt instructions and Python utilities for creating and manipulating pdf, docx, pptx, xlsx files - and you can ask Claude for a copy and learn a TON about working with those formats simonwillison.net/2025/Oct/10/...

I swear using @cuelang.org is like having superpowers Just CUE-ified the lexicon for permissioned spaces, so much easier to have consistency and readability. The JSON form is generated into the expected directory. github.com/blebbit/atpr... #atdev #atprotodev @atproto.com

It makes me really happy that this talk is (still!) appreciated. Quite surprising but deeply gratifying. #golang

Some nice languages changes here and in the near future. "error" in particular should be a real QoL improver. #cuelang

@crawshaw.io Half way through my first sketch.dev run. Looking promising so far! One thing I'm really liking is the ability to interject comments while it's thinking and see its trajectory change.

AI newbie question here about practicalities: I've got a Pixel 8, recorded some audio on the Recorder app; how do I get ChatGPT and its app to see and analyze that audio?

At least for #golang, avoid using deps.dev for now. It seems to be reporting security advisories based on outdated information, and the project seems unmaintained, as I reported this two weeks ago but got nothing at all.

📣 We have just released CUE v0.13.0 - culminating a year's worth of work to enable the new evaluator by default 🎉 It also packs in lots of new features, such as support for absolute module packages, dozens of JSON Schema improvements, and a new experimental XML encoding.

Three Trail of Bits engineers audited core Go cryptography for a month and found only one low-sev security issue... in unsupported Go+BoringCrypto! 🍾 Years of efforts on testing, limiting complexity, safe APIs, and readability have paid off! ✨ Yes I am taking a victory lap. No I am not sorry. 🏆

OR alternatively learn many other languages and realise that there are many trade-offs and that Go occupies a tricky-to-attain balance between them, and is a better language for it.

In a fit of sleep-deprived procrastination, I made a generator for Fastmail rules using cuelang.org. Really fun! Exported as JSON, iterated in validation mode until I had a strict Cue definition, added templating to make a DSL, imported generated JSON. Manual export/import "APIs" are underrated.

A reminder for #golang folks joining Bluesky - here's a starter pack of contributors to the Go project!

This is worth being aware of. There are more important battles to fight.

How long before they put it behind an MCP server, hook it up to an LLM and prompt with "Let's play global thermonuclear war"?

📣 We have just released CUE v0.13.0-alpha.4 - with further fixes and optimizations for the new evaluator, and introducing an experimental XML encoding 🎉

Dear #kubernetes folks, can anyone tell me if there's a reliable way of mapping from a resource definition in the K8s OpenAPI spec (e.g. github.com/kubernetes/k...) to the `apiVersion` and `kind` values required for that resource?

worth knowing about

in which chatgpt tells me about it's undocumented hardcoded boundaries and some of the ways it's trained to be intentionally deceptive. (i got here by proving that it had done facial recognition for me in the past, after it denied doing so for a while. once it "remembered," it stopped obfuscating.)

Looks like the evidence for this weird chemical abundance in an exoplanet atmosphere has gotten stronger with new JWST data: www.nytimes.com/2025/04/16/s... Is it really a sign of life? That’s still not clear; lots of analysis left to do. But it’ll be interesting to see how it all pans out! 🧪 🔭

Missed Tuesday's community call? No worries - you can find a recording and the slides here: github.com/cue-lang/cue...

TIL. Also has a useful aside about #golang GOOS and GOARCH.

Something weird up with the bsky app on Android: it prompted me to log in and now it rejects my login with "Incorrect username or password". I can still log in on desktop with that password. wtf is going on?

Ka-ching! Can't believe I haven't read it already. I'll probably start reading it and find out I have, mind.

I had not heard this but it sounds totally plausible and a quick search seems to back it up.

So this is essentially what's going to happen, right? (apologies for the AI-generated image)

Now published to github.com/rogpeppe/ioseq so you can easily try it out. It's not very well tested, so there are almost certainly still bugs! #golang

Speaking of iterators, I just wrote up a little proposal. #golang github.com/golang/go/is...

@mvdan.cc @myitcv.io any chance you could pick one of these up for me? I'd love a copy if one is available (I don't mind much if it's signed or not). I'll pay whatever :)

I am absolutely revelling in #golang iterators these days. An absolute pleasure to use.

Experimenting with functions in the OpenAI API. For an arbitrary first task, I gave it a "get temperature at location" function and the instruction "When should I plant my potatoes?". It tried to call the function with {"lat":37.7749,"long":-122.4194}. Why here?! www.google.co.uk/maps/place/3...

That Adam Roberts is not more widely known and has not won many more awards is the single most mystifying thing to me about the SF genre. In a prolific career of more than 20 years he has produced *the* most varied, thought-provoking, witty and beautifully written body of work. Publishing eh?

An excellent book, well worth acquiring.

@simonwillison.net What's best practice for dealing with rate limits when running llm?

Nice #cuelang success story medium.com/safetycultur...

But it gets even more wild... 🥁 Magpies also use anti-bird spikes for their nest. And this is my favourite... a nest made out of 1500 nasty metal spikes! 👀 It contains 50 meters of stolen anti-bird strips. The ultimate rebels. Look at this incredible build! 🤯

@rog.bsky.social and the CUE Team have published the first curated modules to the registry. #cuelang tip.cuelang.org/docs/draft/c...

If you do want to know how it works—and, specifically, how it can work in the US, here’s a thing I wrote: substack.com/home/post/p-...

If you see this, quote post with a beach photo from your gallery if you have one.

I wonder which ChatGPT content policy I might be breaching. The guardrails are seriously getting in the way here!

Is it possible to make a blueksky feed that excludes any skeets I've seen already?

out on Friday! #celticmusic #celticpiano #folk
