VDPAU is the Video Decode and Presentation API for Unix [1]. I noticed an error with mplayer “Failed to open VDPAU backend libvdpau_i965.so: cannot open shared object file: No such file or directory“, Googling that turned up Debian Bug #869815 [2] which suggested installing the packages vdpau-va-driver and libvdpau-va-gl1 and setting the environment variable “VDPAU_DRIVER=va_gl” […]

For a while I’ve had a problem with my Thinkpad X1 Carbon Gen 1 [1] where storage pauses for 30 seconds, it’s become more common recently and unfortunately everything seems to depend on storage (ideally a web browser playing a video from the Internet could keep doing so with no disk access, but that’s not […] It’s been over 6 years since my last post comparing 3G data plans in Australia. I’m currently using Aldi Mobile [1]. They have a $15 package which gives 3G of data and unlimited calls and SMS in Australia for 30 days, and a $25 package that gives 20G of data and unlimited international calls to […] The G-Force Wikipedia page says that humans can survive 20G horizontally “eyes in” for up to 10 seconds and 10G for 1 minute. An accelerator of 14G for 10 seconds (well below the level that’s unsafe) gives a speed of mach 4 and an acceleration distance of just under 7km. Launching a 100 metric ton […] Business Insider has an informative article about the way that Google users can get locked out with no apparent reason and no recourse [1]. Something to share with clients when they consider putting everything in “the cloud”. Vice has an interestoing article about people jailbreaking used Teslas after Tesla has stolen software licenses that were […] Version 2.0 of ZFS has been released, it’s now known as OpenZFS and has a unified release for Linux and BSD which is nice. One new feature is persistent L2ARC (which means that when you use SSD or NVMe to cache hard drives that cache will remain after a reboot) is an obvious feature that […] One of my workstations is running Debian/Unstable with KDE and SDDM on an AMD Radeon R7 260X video card. Recently it stopped displaying things correctly after a reboot, all the icons failed to display as well as many of the Qt controls. When I ran a KDE application from the command line I got the […] KDE has a long term problem of excessive CPU time used by the screen locker [1]. Part of it is due to software GL emulation, and part of it is due to the screen locker doing things like flashing the cursor when nothing else is happening. One of my systems has an NVidia card and […] I’ve had a saga of getting 4K monitors to work well. My latest issue has been video playing, the dreaded mplayer error about the system being too slow. My previous post about 4K was about using DisplayPort to get more than 30Hz scan rate at 4K [1]. I now have a nice 60Hz scan rate […] I’ve been investigating the options for tracking system statistics to diagnose performance problems. The idea is to track all sorts of data about the system (network use, disk IO, CPU, etc) and look for correlations at times of performance problems. DataDog is pretty good for this but expensive, it’s apparently based on or inspired by […] |
