Year-end donations round, 2025 edition
One more year, one more year-end donations round before reaching the next one. As every year, I highly encourage you to do the same. Please think about organizations that make a difference to you and software that you may use every day. Your contribution may make a difference to them in return.
This year I went with:
Signal because I still use it every day. In reality, I’ve promoted this donation to a monthly recurring one and I’ve been donating throughout all the year, but I’m still mentioning it here.
KDE because I’ve recently switched to it on my personal computer, just to...

I approached this subject rationally, aiming to explain certain metrics I observed in my log files. I began exploring the Hacker News algorithms, along with related posts by other authors and,...

Domains as "Internet Handles"
A little while ago I cam across a post by Dan Abramov, a name that until then didn’t ring a bell, but who appears to be a former Meta employee and member of the React core team. The post links to a website made by Abramov, that addresses the issues of how, quote, every time you sign up for a new social app, you have to rush to claim your username, how, quote, if someone else got there first, too bad and how, quote, that username only works on that one app anyway.
The website goes on:
This is silly. The internet has already solved this problem.
There already...
