What kind though?

Thanks, ruby was another language I saw in the thread popping a few times, the first one being python. I I was told a few things python can be good for, can you give me a few examples of good uses for ruby just to have a vague idea?

Fediverse. Also I hate that mastodon is seen as the fediverse. I had to explain to someone like they were a 5 years old I was using pleroma and they kept saying that no, I didn't understand, we're on mastodon. He didn't get the concept at all.

If your laptop is on the potato side I would personally avoid kde, it's much lighter now than it used to be but still heavier than other options. Mint looks good in my personal opinion and, again in my opinion, is a better alternative if compared to ubuntu, it's based on it but with some improvements. The default flavor comes with cinnamon, but if your laptop struggles it's also available with xfce, which even older machines should be able to handle.
