    I can certainly see a lot of parallels with Oculus / Facebook. Perhaps unusually, I actually wanted FB to impress itself more strongly on Oculus post acquisition because, frankly, …

    My primary concern is for immersive VR media on our Go and Quest platforms, which use Snapdragon 821 and 835 SoC, respectively. The 821 doesn’t support 10 bit on anything, and the …

    I was prepared to blend the edges, but it turned out not to be necessary. If the compression ration was increased enough that there were lots of artifacts in the low res version it…

    I just tried, and while it does decode a 6kx3k 60 fps video, which is very admirable, it doesn't hold 60 fps while doing it. There are probably encoding options to minimize work on…

    Following up on the links you gave me on Twitter. These two fall into the awful pop-sci writing category: http://www.economist.com/blogs/freeexchange/2013/09/working-... “And it se…

    I find these “shorter work weeks are just as effective” articles to be nonsense, at least for knowledge workers with some tactical discretion. I can imagine productivity at an asse…
