Technology Decisions’ weekly wrap of IT fails, latest tech, new must-have gadgets, ‘computer says no’ moments and more.

If it can happen to him … There must be red faces in the offices of Twitter this week, and none redder that that of the company’s CFO, Anthony Noto, whose Twitter account was hacked.
