As I have mentioned many times, you should know where to go when you need help in technology. Mercury Magazines and TradePub offer free technical magazines and books, but there is one catch. They ask for your job information — your email, where you work, how big the organization is and what you do. If you are okay giving out personal/job information, take advantage of this offer.

Note that this is not an advertisement, but simply me telling where you can get resources for free.
