Update: fixed! The recently-released FTL by Subset Games has a problem with the 12.8 AMD Catalyst Drivers, whereby the jump map and enemy ships are not rendered See below) due to an issue with edge detection in anti-aliasing. The fix is to create a custom profile for FTLGame.exe in the Catalyst Control Center to over-ride [...]

This is another case of “should have read the manual”, but there are ways to see previous output in both screen and byobu. In screen: ctrl + a + [ In byobu: F7 These key combinations cause screen/byobu to enter copy mode, where you can navigate using vi keys, can set marks for copying using [...]
The media browser on my LG TV has been acting up recently. Instead of listing the categories set up in Plex it pops up a dialog saying “Warning: Not Found”. It does this despite being able to see the Plex Media Server (going to ‘bowse sources’ or similar brings up the server’s name but selecting [...]
Mousing to the “hot corner” in Cinnamon gives an overview of current workspaces, à la expose. Unfortunately a careless click can close one of those workspaces, as I found out last night. Equally, you may feel that the default 2 workspaces is too few and wish to expand upon that. Now, I think the numvber [...]
http://linux-knowledgebase.com/en/Tipoftheday/February/error23errorwhileparsingnumber saved my server. It wasn’t booting after an upgrade to Debian Squeeze, despite following the upgrade instructions. Connecting to the serial console showed there were problems with finding root (grub error while parsing number, error 23) which was at md1. Changing the first line to root (hd0,0) and adding initrd /boot/initrd.img-2.6.32-5-amd64 allowed the system [...]
Because I keep forgetting, here’s a reminder to myself of the correct way to iterate through files and directories in bash, even considering spaces in filenames, whith a hat-tip to Thomas Howard Uphill: find . -type f|grep .ext$ |while read file do /do/something/to “$file” done Silly rabbit.
I was doing my initial “is it working?” tests after reinstalling mpc, and mpc ls was not giving me any output. ncmpc was also showing no files. What I didn’t appreciate was that the music database is no populated by default- you have to issue an “update” command manually (or semi-manually by running a client [...]
There are a number of ways of showing the progress of a dd copy. The easiest is sending the USER1 signal to the dd process, like: dd if=FILE1 of=FILE2 pkill -USER1 dd But that only gives a current status – eg 12345678 bytes transferred (11.77MB) … [8.56MB/s]. Not that helpful if you want an ongoing [...]
I was using scp to upload some files (as you should!) and maxing out my connection while doing it. It made using ssh problematic! Fortunately there’s an easy switch to use to limit the rate: scp -l 1024 /file1 user@host:/file2 The -l switch limits scp to the specified upload rate in kilobits per second. Handy!
A I may have mentioned, I recently reinstalled Ubuntu (had been using Windows 7 for a few months). Since the reinstall I had changed my common login password for the other computers on the network so of course I updated my user password for the new install. The slight problem came when I used any [...]
