Linus Torvalds releases subsurface dive tracking software
Linus Torvalds, the creator and maintainer in chief of the Linux kernel, is also well known for his hobby of scuba diving and – as The H-online reports – he’s has just released subsurface, a dive-tracking program he wrote after discovering that no dive log software worked for him.

Subsurface runs on Linux and uses gtk2 for the GUI. It can process XML dive files or work directly with any dive computer supported by libdivecomputer. It supports import, PDF export and printing, and produces visual dive charts. Subsurface is licensed under the GPL2 and Linus is inviting developers to contribute patches.
