Free Geek Books
I’ve talked before about how wonderful Stack Overflow is. I found this great post today listing free books and quick reference cards. There are a lot of out of work geeks out there that could use a refresher or some cross-training.
The largest sources out there seems to be Added Bytes and 37Signals. I hope to compile and publish a list soon too, because I have a bunch of links to documentation on various software packes and languages.
