No: #qubits are not 0 and 1 at the same time. Let’s dive into #quantum computing to understand that the reality is much more subtle. 🤏 itnext.io/stop-saying-a-qubi…

Like always @blackfireio helped a lot measuring the impact of the new @symfony JsonStreamer component! Serialization's share of the total request fell from 83% to 45% thanks to streaming – achieving an awesome 70% time saving and 50% memory reduction!

Microsoft quietly released an MCP server that converts any Office file (Powerpoint, Word, Excel) to markdown: markitdown-mcp

The french Moutain and Climbing Sport Federation @FFME_officiel just sent an email to report a data breach ☠️. All personal information of their members (present and past) was publicly accessible. I'm not surprised, I warn them about the vulnerability in July 2021 🤷‍♂️ !

La @FFME_officiel vient d'envoyer un email à tous ses adhérants pour les informer que leurs données personnelles ont fuitées ☠️. Je ne suis pas surpris, je leur ai signalé la faille en Juillet 2021 🤷‍♂️ ! Il y a putain de 3 ans et demi 🤬! 🧵détails ⤵️ 1/7

2023, au détour d'une compétition j'échange avec un président d'une des ligues de la fédération. Alarmé par la situation, il me demande de lui faire un email pour qu'il "remonte le problème". Le lendemain je lui envoie un email avec toutes les informations 😒

Depuis, aucune nouvelle... jusqu'au message de la fédération de ce matin 🙄 Je ne vais pas donner de détails sur la faille, car je ne suis même pas sure que c'est bien elle qui a été utilisée, et si la FFME a bien corrigé le soucis. Cela risque de se retourne contre moi 🤕

this project is so cool! next time I need to implement a loop that does nothing 1 billion times, I know where to find the fastest language for this!

More languages, more insights! A few interesting takeaways: * Java and Kotlin are quick! Possible explanation: Google is heavily invested in performance here. * Js is really fast as far as interpreted / jit languages go. * Python is quite slow without things like PyPy.

Replying to @matthieunapoli @brendt_gd
ie. ideal world for me: only « extends » (remove traits & interfaces) and allow multiple inheritance. Much simpler :)

Thanks to a couple contributors, Ghostty has built-in VCS branching characters. Kitty introduced this[1] and I think Ghostty is the second terminal to implement it. The cool detail in this one: for the end markers they're drawn with a true fade (see line 13). [1]: github.com/kovidgoyal/kitty/…
