I absolutely adore this Dilbert comic, not really strictly Computer Science nor illustrating a concept, but I think it is pretty funny.

Seems that the testimonials from others on here show that he was nothing but lovely, I don't think that making observations like that on a post like this is terribly appropriate though.
Although not exactly like Dwarf Fortress, I've been playing Songs of Syx[1] recently and it's incredibly good. It is made by a single developer and it is super fun. It's more of an Empire building game, and it checks a lot of the boxes I want out of these sorts of games. I can see it becoming even more impressive and as time goes on. Demo is unlimited and free, it's just 3-6 months behind the paid version with features, so if you like it definitely support the dev.
The AUR is the main thing I miss after moving from Arch to Gentoo, the scope of the applications on the AUR is crazy, and for the most part in my experience it's usually up to date and reliable. In my opinion, the AUR alone is enough reason to install Arch or an Arch-Based Distro.
