No Starch Press is teaming up with Humble Bundle again to raise money for the EFF, the Electronic Frontier Foundation. Pay $15.00 to help support the EFF and receive a bundle of thirteen eBook titles.
Some of the titles are: Hacking: The Art of Exploitation, Hacking the XBox, Automate the Boring Stuff with Python, Python Crash Course, Practical Malware and The Linux Command Line.
Any amount gets you four titles and a $15.00 donation gets you all 13. You decide how much goes to EFF, No Starch or Humble Bundle.
