Well, wasn't I pleased to see Half-Life 2 and its episodes show up in Beta form on my "Linux Games" list? From now on, I need never boot up Windows again! Well, okay, that's an exaggeration, I'll still need it for coding games and playing Portal 2 for the moment, but anyway! Portal 2 definitely can't be far off now!
I'm not sure if this means that the HL2 games are now on a newer engine version, and if so whether that means more or fewer bugs. I'm not going to test it straight away.
Also, for those who have not yet checked them out, I have decided to post my YouTube videos on nuclear physics right here:
They cover protons, neutrons and the nuclei of the first three isotopes of hydrogen.
