Make posix build target paths configurable via env vars by attilagyorffy · Pull Request #5045 · savonet/liquidsoap
Summary
Packagers (e.g. Homebrew) currently need to patch the source with inreplace to override the
hardcoded paths in liquidsoap_paths.posix.ml. For example, the proposed
Homebrew formula does:

Running this as an experiment — #self-hosting my own Bluesky PDS on my #homelab. Custom Prometheus exporter for repo, sequencer, and S3 metrics in Grafana. If this proves stable, I'll migrate my identity here permanently. AT Protocol makes it possible: your DID is yours, switching PDS is first-class
Took ownership of my social identity today. Running my own Bluesky PDS — my posts, my keys, my data, on my own hardware. Your identity is portable, your data travels with you, and no one can take your handle away. This is what decentralised social should feel like. #atproto #bluesky #selfhosted

Took a moment to think about what #opensource actually means in 2026. Not the usual pitch about freedom and community — more about plumbing, Nebraska, and why nobody thinks about #infrastructure until it breaks.

Open Source Is Just Plumbing Now
It's not idealism. It's the infrastructure under every bank, hospital, and government system you depend on.

Redesigned my personal site & consolidated everything — blog posts, essays from scout.engineer, curated tweets, projects — into one place. IBM Plex Mono throughout, five CSS variables for the entire theme, light and dark. No frameworks, no build step. Just HTML, CSS, and enough whitespace to breathe

If a function takes some dodgy raw string, interrogates it, validates it, and only then lets it into polite society as a proper type, that’s not New. That’s Parse. Apparently I now have opinions about Go naming. Tragic.

Stop Naming Your Go Constructors New
Why Parse is better than New when your Go constructor is really parsing a string.

#Protip: Validate LLM responses before caching them. We cached truncated JSON (max_tokens cutoff), then every retry hit the same broken cache. Now: parse into a typed result first — if it fails, don't cache. On cache hit, re-validate; bad entries self-evict and retry fresh. Now our cache self-heals!

#Protip: Model state machines as types. Example: an order goes Draft → Submitted → Paid. Then pay(order) can require a SubmittedOrder, so paying a draft fails at compile time. The compiler blocks invalid transitions before the code ever runs.

Just dug up a blog post I wrote in early 2007 about my first steps with #RubyOnRails. Which apparently means I started on Rails 1.2 — a version so old it ran on steam and optimism. URLs barely had REST, I barely had a beard. Wild times. 🫢

The navigation in Apple Music (formerly iTunes) app on macOS is absolutely terrible. It's no outlier in the swarm of "wanting it all" kind of modern music players that pack way too many things ― podcasts, videos and now even DMs (really Spotify?!) ― into their jammed-up UIs. Absolutely disgusting.

Every few years I try giving @ghost.org another chance as a feature-rich home for my blog… and, like clockwork, it greets me with a fresh slap in the face. Truly a tradition at this point.

As I've turned 40 today, I find myself thinking more about how I can help build a healthier, more public internet. In this article I argue that real freedom means owning your identity, data, and connections — not just spreading them across more servers.

I don’t think I’d ever said ‘it better be worthwhile’ until today — when a colleague asked for a PR review during my lunch break as I was watching a video about cute beavers 🦫 building a dam the mayor sadly said had to be removed.

It’s great to sometimes work from different places, like from a coffee shop. Coding whilst listening to heavy bass music in your headphones. Oh, and it’s a totally new experience when you realise others are looking at you after you’ve dropped a serious bass face. 😅
