Today I saw an ATM in a bank, that seems real, with a Windows version that needs to be activated! 🤯

You MUST listen to RFC 2119 It turns out you can just pay people to do things.

I've referenced it enough that now it's all I can hear when I read it. Now you have to hear it too 🙉 ericwbailey.website/published/yo...

Il y a des disclaimer sur les versions texte, mais les versions vocales ne mettent pas ça.
(qui plus est je pense que ça va être comme les les messages "boire de l'alcool est mauvais pour la santé" ou "au quotidien prenez les transports en commun")

C'est malheureusement le risque de L'IA : tu es ici sur un point trop spécifique pour qu'il soit pertinent. En plus de ça, il a probablement agrégé des réponses de plein de gens qui se posent la question ou même donne la mauvaise réponse.

I updated #immutablejs documentation to avoid indexing old version, and it starts to work.
Weirdly qwant has indexed the v5 page while Google still index the v3 😒

#immutablejs documentation now have a page about the devtools browsers extension!

mas.to Hello! mas.to is a fast, up-to-date and fun Mastodon server.

Je trouve quel les comptes US ont plus migré sur bsky et du coup j'y trouve plus mon compte dans les gens que je suis pour la veille tech.
J'ai toujours du mal à trouver mon compte sur masto, même si l'ambiance est plus "cozy".

Why timezones are complicated? Just look at this slide and the next one 😅

ITS HAPPENING

Firefox 127 shipped today making it the first browser to support Temporal - the new API for working with Dates, times, timezones + durations

You might want to look at Vivaldi browser : it's chromium based too and has a lot of customization options.

Ça me fait penser aux GPS : les gens ne savent plus se repérer dans une ville sans GPS, et la deuxième fois que l'on revient… on remet le GPS car on n'a pas mémorisé le trajet.
Est-ce que ça va faire pareil avec l'IA ? L'avenir nous le dira 🙃

Clairement on est a la croisée des chemins sur l'IA.
Je n'ai pas encore fait mon article de blog sur mon avis (j'ai juste le titre 😄).
L'IA est un bon outil, je l'utilise aussi pas mal, mais je pense qu'on y pend la connaissance, et parfois revenir au départ permet d'apprendre et de mémoriser !

Two lines of Cross-Document View Transitions code you can use on every website today Arguably, the most profound thing about the web is the ability to link one page to another.

The one where I muse about how this simple bit of code radically changes how the web itself seems to behave…

Immutable.js Object Formatter - Chrome Web Store Makes Immutable JS objects more readable when they are logged to the console.

The #immutablejs browser extension is back!
You can have a human-readable version when you `console.log` an immutable object.
Bonus: it's now available for Firefox too!
For chromium-based : chromewebstore.google.com/detail/immut...
For Firefox : addons.mozilla.org/fr/firefox/a...

Surtout que même les applis de Google mettent ce genre de messages !

Focus on tabs of a browser. Two tabs are grouped under the name "coucou", three tabs have their menu opened on the "add tabs to group".

Firefox released a feature that is great in @vivaldi.com : the possibility to "group" tabs together !

#immutablejs chrome extension doesn't work since chrome requires manifest v3 for extensions.
I am working on releasing a new version soon.
Bonus : it will also be available on Firefox! 🎉

A code snippet showing how to use the new PHP pipe operator from the v3 RFC. function getUsers(): array { return [ new User('root', isAdmin: true), new User('john.doe', isAdmin: false), ]; } function isAdmin(User $user): bool { return $user->isAdmin; } // This is the new syntax. $numberOfAdmins = getUsers() |> fn ($list) => array_filter($list, isAdmin(...)) |> count(...); var_dump($numberOfAdmins); // int(1);

#PHP on a good way to get a pipe operator with: wiki.php.net/rfc/pipe-ope...

A way to chain callable, passing results from left to the first argument on right, like a bash pipe operator.

It eases reading code compared to callbacks, and less error-prone than temp vars.

So cool to see that issues reported for immutable-js now contains playground link!

Oh crap, I haven't blogged since december! I need to write an article soon!

I'm doing the exact same opposite: I accept only people that I've met somewhere else (internet beeing a valid place but somewhere out of LinkedIn)
