Sorting Two Tons of Lego, the Software Side
All the software written for this project is in Python. I’m not an expert python programmer, far from it but the huge number of available libraries and the fact that I can make some sense of it all without having spent a lifetime in Python made this a fairly obvious choice. There is a python distribution called…

Some things have changed in the mean time and I might've phrased a few things differently if I had written this today. But still, what's here below is what I wrote back then. … Continue reading curl is C →

OpenAI bots knew about the RubyGems caching vulnerability
Today Reuters and the Wall Street Journal both reported about rogue AI agents at OpenAI attacking RubyGems.org. https://www.rubyhack.ai/ has an amazing writeup, and you should read it. I just wanted to make a quick post about it because it’s wild. TL;DR: It seems like OpenAI Bots knew about the RubyGems caching…

The insane amount of backward compatibility in Google Maps
I still keep a couple of my favorite old smartphones. Sometimes I use one of them as my primary device for fun. Phones are among the fastest evolving markets, even a year makes a whole lot of differences. One of the biggest challenges with using old phones is the software: they don't run modern software.

Git git git git git
Ever found you’ve accidentally entered too many gits in your terminal and wondered if there’s a solution to it?
