Not every open-source project wants more contributors right now, and that's fine. Four shapes maintainers run — walled castle, clique, university, hippie commune — and your `CONTRIBUTING.md` is saying the quiet part out loud. No wrong answer, just an honest one. blog.stdlib.io/do-you-want-...

Geology of the Tour de France@geotdf.bsky.social · 3w agoToday's Tour de France stage ends at Le Lioran, at the top of the Cantal Volcano, Europe's larges stratovolcano. Two years ago, we made this clip there, our favorite :) How volcanism led to the invention of the bicycle! @vanhinsbergen.bsky.social @uugeo.bsky.social

#GOTOpodcast: @rtfeldman.bsky.social and @anjana.dev talk about rewriting the Roc compiler from Rust to Zig during the exact period AI coding tools went from interesting to really useful. 🎧 Listen to the episode: gotopia.tech/podcast
New Elm release today! 🎉 0.19.2 🥳 Incremental builds of 850k lines of Elm in <350ms. Gearing up for a batch of smaller releases as we head towards Elm 1.0. elm-lang.org/news/faster-...
Nice day at @oss-torino.bsky.social setup a new meta oss repo and played with an obsidian vault as a git repo workflow. played with Claude, both from ghostty and with claudian obsidian plugin. Nerd sniped by someone working on mojo python interop to do the same with Nim codeberg.org/pietroppeter...
“We want to like ourselves, not please ourselves” (in this likely wrong translation I am tempted to go with both)
new post: how I develop recently using local models. the tooling is now good enough to do agentic workflows and everyone should give them a try! vickiboykis.com/2026/06/15/r...
Running local models is good now
Local agentic coding has gotten great over the past few months

“The shortest distance is not necessarily the best one, if you want to go to London you do not start walking there, you go on your computer do buy the tickets; same with llm, ask them to write code to do the thing”
I did not know there were so many variations of the “there are only two hard things…”; the last one is killing me 😂 www.martinfowler.com/bliki/TwoHar...
I blinked and it seems Smartboxes are having a come back. Did they make the rounds and become vintage? Addio stress per due!
Dalla mia timeline su X ogni 3 post vedo questo. Non ci passo spesso e non ci faccio troppo caso ma un tale livello di spazzatura è notevole
You come back from a conf, you see a duck and you think @duckdb.org. Mischevious marketing plot! Beware #BigDuck gets in your head!
Era da un po’ di tempo che non mi sorprendeva un ristorante. Ottimo polpo su pappa al pomodoro e spaghetti calamari e canellini (con mollica e piccante)
Timeline cleanse. Take a breath, maybe consider getting out of here (or not). Have a splendid day! ⛰️ 🧘♂️
While listening to this morning keynote at PyCon Italia, my brain made a weird connection between languages, performance and community. Diego was speaking about how the performance was not a problem early on and trade-off was on making compiler code readable and lower complexity. Focus on community
“Sicilia come Persia o Venezuela, diceva Elio Vittorini”. Di questi tempi, speriamo di no…
finally I had some time and mental space (and emotional space) to test claude code. Genuinely impressed with the output and had really fun working with it for a two hours session with only prompting (warning: niche project about logic puzzles and nim language). github.com/pietroppeter...

I have been playing with a new kind of puzzle a word based mini sudoku where you have clues with word to insert (it is basically the seek and spell sudoku found on gmpuzzles minus the arrow and minified). It is fun. My 6 year old also has fun with it. Working name: parloku
