I like to build things.

Helping companies adopt #Nix and #NixOS at https://numtide.com
I love to see PRs like this.

By defining a formatter spec, treefmt keeps its code simple, and slowly pushes the formatter ecosystem in the right direction.

It works surprisingly well.

Make `--write` only write on change by dani0854 · Pull Request #41 · reteps/dockerfmt
Currently, even if there are no changes --write will still write to file, changing its last modified timestamp. This causes a problem for things that monitors file modification by that timestamp. F...

Prediction: one or more languages will emerge, optimised for LLMs to talk to each other.

We'll start seeing Tweets that humans don't understand.

Did anybody use www.citadel.org?

Every few years I run into it, and it has this intriguing set of features and vibe. BBS for the Web.

I'm curious if any businesses are using it.

My wife was happy with her Pixel 4a phone. Last week Google pushed a software update, and now the battery is draining like a sieve. Google doesn't explain why this happeend and how to fix this.

Is anybody using determinate.systems/posts/magic-... ?

Kinda wondering if it's worth rewriting it in TypeScript.

Nix 2.26 is out!

The biggest change is how path sub-flakes are handled. Previously, their input was locked by a hash which led to confusion from users.

With that change, having a `./dev` sub-flake now becomes practical.

Reminder that you can get unfree+redistributable binaries (eg: CUDA, ZeroTier or MongoDB) from the nix-community.cachix.org cache.

I noticed today that this knowledge is not widely available.

Did you ever deploy your NixOS configuration to the wrong host?

It happened to me a few times. Luckily it's easy to revert but it can cause downtime and state folders to be left around.
