So I thought about this and I think it is actually

1.32
₁42

And the small 1 before 42 is that 1 you make when you add the tens digit in an addition. However there should not be another tens digit involved, and also 0.32+0.42 is 0.74 and not 0.64, and also I think this started as a multiplication.

Regarding the 1.80, I also thought about this but I got no fucking clue.

You are right, I was a bit too harsh, sorry for that. I saw Linux and then my “information should be open for everybody spidey sense” rang. Of course you are allowed to make money for your work. I am not a very big YouTube fan and I don’t like YouTube posts though.

I agree, not clicking that link. The aim seems not to spread information, but to monetize it. If you wanted a video you could just use PeerTube.

I am a programmer and have a little server that runs Debian. On my desktop PC I run Linux Mint and I absolutely love it. It just works. In 2026 there is no good reason to got with Ubuntu anymore.
