“The thing we’re doing will destroy really important stuff but don’t worry it’ll eventually get better, probably. Anyway, give us all your money.”

Hier je suis intervenu dans une école, comme depuis maintenant 4 ans. C'est toujours un moment où je reçois autant que je donne, c'était encore le cas hier 🤗. Merci aux étudiant·es présent·es, c'était passionnant 🤩. Mais, car il y a un "mais" ⬇️

I am not rage quitting Open Source reviews, but I am changing: andrew.nerdnetworks.org/blog/2026/10...

Nouvelle vidéo : « Ils ont copié IBM dans le plus grand calme (clean room) » Dans cette vidéo, je vous propose de découvrir la technique de « Clean Room » utilisée et popularisée par Compaq et Phoenix pour réimplémenter le BIOS de l’IBM PC 🔗 youtu.be/epJm1LccK30

J'ai passé un très bon moment avec l'ami @emmanuelbernard.com au studio @devoxx.fr à discuter de Rust, et aussi de plein d'autres choses. Et comme il dit, on aurait pu discuter des heures 😜

The talks at #EuroRust reflect the wide variety of domains where Rust shines: network servers, high performance calculation, including on the GPU and even… Ikea lamps! Well, embedded systems, actually 😛

#EuroRust day 2. Really a great conference with in-depth topics and a great community!

No joke. I think this is the most important video I have ever seen about mobile games. This guy breaks down how this game psychologically profiles you, and makes the game harder or easier in order to show you ads

On my way to Barcelona for #EuroRust !

If you enjoy working with large-scale data processing systems and you want to stay relevant, you have to learn Apache DataFusion. Slowly but surely, it's replacing many other tools. The RAD stack (Rust, Arrow, DataFusion) is the future. One example: www.datadoghq.com/blog/enginee...

I wanted DuckDB on Google Cloud without babysitting a VM, so I built DuckLess 🦆☁️ Run SQL or Python next to your GCS data, then the machine disappears. 📊 100 GB of Parquet: 47s for a few cents 🚀 Open source, v0.4 What would you run with it? 👇 #GoogleCloud @duckdb.org @developers.google.com #data

github.com/lloydmeta/st... My kid wanted to extract the different "stems" from a track (guitar, drum, vocals etc) so she could practise songs she likes, and to be able to slow it down while muting/unmuting different stems that you can download as mp3/wav. [1] #creative-coding #vibecoding #music

Beyond Suno and generative music, the music software scene is flooded with vibecoded plugins. This post starts with a great explanation of AI-assisted coding vs vibecoding. It's all about understanding what you're doing and staying in control.

Quand un mathématicien vous dit que l'IA a ruiné son métier et que vous lui répondez qu'il va pouvoir se concentrer sur d'autres problèmes ou des choses "plus intéressantes", vous n'écoutez pas ce qu'il vous dit. Pareil pour un informaticien, un artiste, un traducteur...

Donc Ecosia abandonne Mistral pour des modèles chinois notamment parce que Mistral consomme de l'électricité nucléaire. Ce délire allemand continue. Plus de division. Imaginez l'argument miroir : "j'utilise pas Ecosia car éoliennes". (Et du gaz et charbon, du coup, après artifice comptable).

Trump is a filthy bastard. His collusion with russia amounts to high treason. While Moscow continues to escalate its massacres of Ukrainians, Trump is offering criminals money. It's a strong incentive for the Ukrainians to bomb russian refineries even more—the Europeans must help them decisively.

I used this trick more than once. Very convenient when you forget your travel adapter!

RIP Margaret Hamilton, the brilliant computer scientist whose contributions to software for the Apollo Guidance Computer were absolutely crucial to the Apollo Moon landings. She also helped shape the discipline of computer engineering while at MIT's Instrumentation Lab: news.mit.edu/2026/margare...

"The model had tried to go beyond its testing environment, but that this was expected and the company was able to prevent it". Nice. This is what doing your job correctly is about. And not "OMG OMG, look how powerful our model is, it hacked random sites on the internet! Stop us or we'll all die!"

A huge increase in Java's FFM allocation performance will appear in JDK28! We've worked hard on this one. Spoiler alert: ~10x speedup on most platforms for a very common use case. inside.java/2026/10/05/c...

It will be interesting to see what the Shelly product line becomes after this acquisition. Shelly is known for a combination of great quality/price ratio for devices that are very open and featured, supporting a wide range of communication protocols.

lol one of our website designers used our organization's entire monthly claude credits yesterday and now half the company doesn't know how to do their jobs. it's october 2nd.

The boom in Linux CVEs lately should get you thinking.

 Surely, given a finite codebase, there are also a finite number of bugs / unintended behavior, thus, a finite amount of vulnerabilities. Theoretically, a “solvable” problem. Right?

 Well…not at all actually.

Si vous commencez le vibe coding, faites tout en Rust. Le compilateur est chiant, contraignant, il vous dit exactement ce qui ne va pas. Et c’est justement pour ça qu’un LLM peut très bien travailler avec. Épisode d’Underscore avec Micode et MatthieuLambda : youtu.be/AiytemqB_F0?...

I will not stop reading code anytime soon. LLMs can generate code that's correct and even performant, but I frequently find it too complex. And I hate accidental complexity - it compounds very quickly and leads to cruft, bugs, and, ultimately, slow and unreliable software.

"5 Corporate Rituals Gen X Refuses to Fake Anymore". Depressingly hilarious and so true! Except that in my case it's more like "always refused to fake" 😜 (via @greenzeebra.bsky.social) www.youtube.com/watch?v=iO8s...

Bon, j’ai regardé le spectacle « historique » donné au Stade de France à l’occasion de la visite du pape. Réaction et analyse d’un show qui développe une vision fantasmée et délirante de l’histoire de France et du catholicisme 1/

My wife caught a germ and has completely lost her voice. She remembered we had kept our kids' Magna Doodle in the basement and uses it to "talk" to me. We didn't expect this toy to be so useful!

It's always DNS. This time it allowed an OpenAI model under test to escape its sandbox. alignment.openai.com/misalignment...

Dear Claude. When I'm asking for a code review, why do you report "plausible" findings that I have to ask you to confirm? Do your job thoroughly, for Token's sake!

Today we're introducing Cloud Sandboxes: same microVM isolation as Docker Sandboxes on your laptop, same CLI, always-on Docker-managed compute. Close your laptop. Keep the agent running. Move between local and cloud with one command. $250 credit for new accounts: docker.com/sbx-promo

Je pense que ça mérite une consultation de l'ensemble de la francophonie. Vous en pensez quoi ? D'autres propositions ? 🤣
