As you might be aware, if you follow Haiku's commits, and it was also mentioned here at ICO, Rudolf Cornelissen is back to his Haiku coding ways. After being away for several years, one of the oldies decided to dust off his Haiku code and has already started working on video drivers, both NVidia and VIA. He also cleaned the cobwebs off his website and has posted a status update, detailing what he's been up to.
Along with the already mentioned work on NVidia (how does dualhead support sound like?) and VIA video drivers, he fixed a few issues with the app_server and has been having a look at getting VESA 3 working on Haiku, though that one might prove tricky.
Head over to his site and read the full update, then join me in welcoming Rudolf back... into the hive... :-)
