I can't believe I forgot to mention the errata! A mentor got so pissed off at Qualcomm one time that he delayed the start of his next contract by a month so he could farm a list of professional electrical engineers working for companies that use Qualcomm chips and developed a relationship with many of them just to create a secret errata sharing network of EEs that were covered under Qualcomm's NDAs. Even a few lawyers at one of the biggest companies who got wind of the idea decided it was worth the risk.

Sadly he passed away before he had the time to really get it off the ground.
