I read a lot of technical papers and books. None are as fun as the comic-esque explainers from Wizardzines. Now, Julia Evans has put everything online, including incomplete comics and single topics such as Sort & Uniq
Wizardzines are wonderful little tutorials that don’t just make good references (or posters) but are more succinct than most technical books.
I'm really thankful for creative smart people like Julia Evans. What a nice contribution to the world.
