I finally finished a side project, thanks to @GitHubCopilot.
Built a small PWA to manage my gift cards: barcode display, balance tracking, etc.
The trick? Assign issues to Copilot and mention it to rework PRs.

Immense respect pour Olivier qui a fait une super présentation malgré un contexte technique plus que difficile. Bravo et merci ! 👏
Le dieu de la technique était contre nous. Pas de vidéoprojection/slides pendant près de 50% de la keynote, perte de l'audio/micro, je suis resté en mode père castor, au talent 😂😂

Merci tout de même aux attendees et à @devfesttoulouse.fr pour leur attention malgré l'adversité 😅
Allez, on se retrouve tout à l'heure pour la conférence d'ouverture de @devfesttoulouse.fr avec mon talk « Another World, une belle leçon d'architecture logicielle » #DevFestToulouse

Impatient de participer jeudi prochain à #DevFest Toulouse pour la première fois et de montrer comment transformer des QR Codes en œuvres d’art grâce à l’IA.

Et comme dirait le stade: « Qui ne saute pas, n’est pas… » 😉

PSA: tips to protect yourself from scams on Signal.

Every major comms platform has to contend w phishing, impersonation, & scams. Sadly.

Signal is major, and as we've grown we've heard about more of these attacks--scammy people pretending to be something or someone to trick and abuse others. 1/

I recently switched to a MacBook Pro with an M4 Max processor. It's meant for speed and the default energy settings reflect this, being "automatic" even in battery mode. If you care more about your battery life than performance, make sure you select "Low power mode" when running on battery.

Is it just me or has the hype around MCP already faded away? Is it because it hasn't lived up to its promise, or is it already boring tech? What's your point of view?

Nice explanation of efficient vector search using product quantization and inverted index (IVF-PQ). Centroids are produced randomly I guess to keep the article short, wondering if this is a viable solution compared to a more costly k-means clustering. lancedb.com/blog/benchma...

Immutable releases announced at GitHub Universe!

Once tagged, releases can’t be changed. No more worrying about malicious actors swapping out assets or moving tags.

Single-use version tags with signed attestations. This is the supply chain protection open source really needs 🔒
