Agile
- Tuleap - sounds too good to be true, probably doesn't work as advertised
Books
- The Electrical experimenter - an archive of 1916-1917 issues of Hugo Gernsback's magazine about amateur radio stuff, electric gadgets, science and other stuff. Fascinating read and so much more detailed than contemporary magazines, although I can't check the facts :P
Debugging
Language
- Master Foreign Numbers - fun exercise, harder than I thought
- Are We Different People in Different Languages?
- The Vatican's Latinist - maybe this was the guy my Latin teacher at school had as an inspiration to tell us the language was not dead
Science
Unicode
Web Development
- urlscan.io - A bit more info that developer console, with the added benefit you don't have to visit the site
