Don’t miss

“Silicon Valley” — The sixth — and sadly, final — season of the tech-centric comedy gets off to a hilarious start as an ultra-jittery Richard Hendricks (Thomas Middleditch) finds himself testifying before Congress about the security of user data. Can he hold himself together long enough to make his case for “a new, democratic, decentralized internet”? On another front, megalomaniac tech titan Gavin Belson (Matt Ross) is in desperation mode as his company, Hooli, is about to be swallowed up by Amazon. (10 p.m. Sunday, HBO).
