Developers' conference season is upon us. Facebook's F8 kicked it off last week with dating, the Oculus Go and AI, AI, AI. Microsoft's Build 2018 is up next, starting Monday, May 7 at 8:30 AM PT (11:30 AM ET, 16:30 in the UK and 1:30 AM Tuesday Sydney time) with its typical two-day keynotes; you can catch Tuesday's stream at the same time, same place, or jump to Google I/O, which starts that day.

You can watch the keynote livestreams here or on MIcrosoft's site (requires registration).
