Ars is on the scene at Microsoft's biggest developer conference of the year.
We're in a surprisingly warm and pleasant San Francisco for Microsoft's annual developer conference, Build, and we'll be liveblogging the opening keynote.
Festivities start at 8:30 PDT. We're expecting to hear all about the next steps in Windows 10's development, including support for the Xbox One, more HoloLens software to show off Microsoft's augmented reality vision, and according to some last-minute leaks, a new way of running Ubuntu on Windows. We're also hoping to hear just how many people are running Windows 10.
