I have been doing a lot of soul searching, and an opportunity has come up for me to move out of the IT business completely. I have decided to take the opportunity.
I love open source and I love technology, but the new position allows me to better peoples lives on a very real level.
That said, I imagine there will be very few updates to this blog from here on in. All of this documentation is creative commons licensed, and if you find any of it useful, take it, adapt it, share it.
Ahh the joys of being a Linux admin. Last week the raid array connected to our main file server suffered a hardware fault. Not to worry we have a backup. I NFS mounted the system from the backup box, and expected everything to work … it should have worked.
I am sure we have all seen the XGL demo with the video palyback being wrapped around the cube. I had seen similar things with AIGLX, but for me video playback did not move untill I had finished switching desktops, or moving the player’s window. Now I know this is pointless, and who cares if video wraps around a cube, but if you want to show off to your friends, making it happen is easy.
A Fedora user emailed me asking for help. He had a dead pixel on his LCD display and wanted to know if there was anything he could do.The simple answer is no. A dead pixel is dead, and most vendors won’t honour a warranty agreement for one dead pixel. But it is not always that simple, what if the pixel is only stuck?http://en.wikipedia.org/wiki/Stuck_pixel says:
A stuck pixel is a common pixel defect on LCD screens, where any number of the 3 sub-pixels are faulty, producing (most commonly) permanent red, green and blue pixels on the screen. Similar to (and often falsely labeled as) a dead pixel, whose 3 sub-pixels are permanently off, producing a black pixel. While one is not very noticeable on a high definition screen, stuck pixels tend to occur in groups, and are most easily noticed on dark or black screens.
Wikipedia suggests using UDPixel, which is incorrectly labelled windows only. UDPixel is written in .Net and mono runs it without too many problems. Download the zip file, extract it, and run: mono UDPixel_en.exe. Hopefully if you have a stuck pixel, this should fix it.
