Kurumin Linux, which was a Brazilian distro based on Knoppix. This was back in 2006 or so, and that was my first hands-on experience with Linux.
I don’t fully remember whether everything worked out of the box, I think it connected to the internet no problem (cable), but what amazed me was:
1 - It ran off the CD drive without needing to install anything 2 - It had loads of preinstalled utility software 3 - Less than 700MB
What really annoys me is the endless stream of scam, “earn money fast with 1 simple trick” ads
It’s literally a scam every single time and trying to report those fall into deaf ears (or blind algorithms) because hey, they’re paying to be shown, why should any high ranking executive care? “Oh, I can’t be held responsible, sorry!”
