How AI is reshaping developer choice (and Octoverse data proves it) AI is rewiring developer preferences. Octoverse 2025 reveals how AI compatibility is becoming the new standard for technology choice.

L'IA influence le choix des langages : TypeScript dépasse Python et JavaScript sur GitHub

OK I did copy the code, I got messed with -code that I took to `$this->code`, I though that it would be `-[]` → `-0`, that the answer would be false, cast to string "false", which is obviously not how casting works at all !

I'm standing with the majority of AI 😅

It would be cheating, isn't it ?

Possibly "false" but it's really a pile of what you shouldn't do in php 😅

En effet !

I gave a conference about open-source, mentioning of course this xkcd, but also mentioning the fact that postcss is widely used, but did not made a lot of money about it ! (in french)

A github modal showing the action of open-sourcing of the transi-store/transi-store project.

Here we go again, I just released a new open source project !

A simple and powerful translation system.

For what it's worth, now that I have migrated our mono-repo, colleagues now ask me:

> Can we add knip on <other repo> too?
> I think that it will help me on my futur task.

But yarn.lock removed lines is cheated! It counts for 800 lines on the diff.

Done on a mono-repo in two times.
What's impressive is that there were no false positive!

Date is out, Temporal is in Temporal is the Date system we always wanted in JavaScript. It's extremely close to being available so Mat Marquis thought it would be a good idea to explain exactly what is better about this new JavaScript...

The Inevitable Evolution of the Developer Role For years, being a good developer meant one thing above all else: writing good code.

Je viens de publier un article sur l’évolution du métier de dev, cela fais suites à quelques réflexions que j’ai eu après des discussions sur ce sujet.

But chances are that your talk will be boring. Why? And how can you avoid it everyone actually hear what you have to say?

Cela dit notre banque à eu une giga panne le jour du retour de vacances, donc on prendra peut être une banque avec CB gratuite en backup.

On a prit un crédit Immo avant d'avoir changé pour une banque en ligne, du coup "obligé" d'avoir un compte chez eux.
Au final on est quand même content d'avoir un conseiller stable quand on en a besoin.
Au passage n26 et révolut sont gratuit parce que leurs frais pour commerçants sont plus cher.
