The first two tips are imo the most important. While everyone wants to try the new syntax, it's best to handle the breaking changes first (mostly codecs), go to production, and leave the fancy new stuff for the next iteration after things have settled down. https://nitter.net/kopaniev

Who says a vacation with a two-year-old has to be about lying on the beach? 😀 Anyway, did anything major happen? I just read about Redis going back to open source and Epic winning against Apple.
