It's useful for example when you are waiting for some server to come online and don't want to keep looking a terminal full of ping timeouts. Remember to check first that the beep command actually causes some noise. text/html 2011-08-28T22:23:33+03:00 http://humdi.net/wiki/tips/configuring-mrxvt?rev=1314559413&do=diff The truth is that I hate terminal emulators that force the use of antialiased fonts. Probably such fonts look nice when the font size is large enough but that usually limits too much how many terminals can be fitted to the screen. I like having space for at least four 80×24 terminals on screen with some extra space around them but that has so far caused antialiased fonts to look blurry and in some way out of focus. Tab support is also the other thing I require from a terminal.

The trick is simple to start fdisk with the following parameters when creating partitions for an empty disk. fdisk -H 224 -S 56 /dev/sdX text/html 2011-08-28T23:50:14+03:00 http://humdi.net/wiki/tips/dokuwiki-with-fixed-width-code-blocks?rev=1314564614&do=diff Code sections should be shown with a fixed width font. However, for some reason DokuWiki (release 2011-05-25a “Rincewind”) didn't do that by default. I tried looking for plugins for solving the problem but the two that I found (xterm and xterm2) were both clearly outdated and buggy. Luckily, the problem can be solved with some simple CCS editing. text/html 2011-08-28T22:51:10+03:00 http://humdi.net/wiki/tips/how-to-disable-ipv6?rev=1314561070&do=diff Current Ubuntu releases have ipv6 enabled by default and in most cases it isn't needed at least yet. Here's a short description for disabling ipv6 but start by checking if it's even enabled currently. ifconfig | grep inet6 If that produced no output then ipv6 is already disabled. Otherwise first open (as root) the file /etc/modprobe.d/aliases and locate the following line: text/html 2011-08-28T22:54:33+03:00 http://humdi.net/wiki/tips/how-to-disable-utf-8-in-console?rev=1314561273&do=diff The purpose of this page is to describe how UTF-8 can be disable in Ubuntu / Debian console. At least Ubuntu releases starting from Dapper have UTF-8 enabled by default after a clean install has been done.

With some fonts, the edge of the font also looks like it has a shadow that isn't gray in color but more like a shade of blue or green. text/html 2011-08-28T22:17:42+03:00 http://humdi.net/wiki/tips/iso-8859-utf-8-and-irssi?rev=1314559062&do=diff This short guide will tell you how to configure irssi so that it will keep showing ISO-8859-15 (or whatever you select) charset letters in terminal no matter what the other users on the channel are using. This way you won't need to worry anymore about UTF-8 junk messing with your terminal that uses ISO-8859-15 or the other way around.

In short, it does what a calendar is supposed to do including reminders and nothing else. However, the preferences dialog is a little bit too simple. Orage doesn't have a setting for selecting if weeks start from Sunday or Monday although the used timezine can still be selected. text/html 2011-08-31T11:10:34+03:00 http://humdi.net/wiki/tips/valgrind-to-xunit-xml-converter?rev=1314778234&do=diff This Python script converts the XML file output of Valgrind to xUnit XML format that can then be used for example in Jenkins.
