Definitely worth sharing, thanks for bringing it here! I love also how the business case is presented in a careful and effective way

Found this amazing little story from @itsfoss.bsky.social about a small logistics company in Italy migrating to Linux that I think is worth sharing! itsfoss.com/linux-storie... I can see lots of SMEs in Spain that would benefit from similar help... (via @pietroppeter.bsky.social on LinkedIn)

Very forceful statement by Terry Tao about AI and math. terrytao.wordpress.com/2026/09/11/a... Note, he is not claiming the models aren't real and powerful. He's talking about how that power should be used. This, I believe, is what all AI discussions should center.

Ten years ago, I founded QuantStack on a conviction: that we could build a sustainable business by supporting world-class open-source software to advance science. We had no outside funding, no guarantees, just trust in open collaboration. Read the full story: quantstack.net/blogs/Decade...

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-...

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

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

“Luxury is the manifestation of uncivilized wealth that wants to impress those who have remained poor. It reveals giving importance to appearances and a lack of interest in everything that represents cultural elevation. It is the triumph of appearance over substance.” 1/3

Luxury is not a design problem. From an industrial design methodology book. Very interesting book (besides the luxury quote) that seems relevant also for data projects (and now I am wondering what is luxury in that context)
