Kde4 map windows key to kickoff launcher

KDE’s equivalent to the windows start menu is the kickoff launcher, being a windows user for a long time before I moved to linux some habits just don’t go away. I tried to change the shortcut key associated to kickoff but as it turns out, KDE treats the Win Key as a meta key. That basically means that just like the Shift, Control and the Alt keys it too has no meaning on its own and must be paired with another key to perform some useful function.

Getting MySQL to work on arch linux

I was setting up the LAMP stack on my arch linux installation, I followed the wonderful arch wiki and had no trouble getting apache and php working but there seems to be a problem with MySQL. It installs just fine but the daemon doesn’t start up.

lovelock# rc.d restart mysqld
:: Stopping MySQL Server [FAIL]
:: Starting MySQL ServerĀ  [FAIL]

I tried fixing the ownership and permissions but didn’t have any success. I realized the cause of the problem after running mysqld_safe

lovelock# /etc/rc.d/mysqld
usage: /etc/rc.d/mysqld {start|stop|restart}
lovelock# mysqld_safe
/usr/bin/mysqld_safe: line 531: hostname: command not found
111209 17:06:03 mysqld_safe Logging to '/var/lib/mysql/.err'.
/usr/bin/mysqld_safe: line 608: hostname: command not found
111209 17:06:03 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
111209 17:06:03 mysqld_safe mysqld from pid file /var/lib/mysql/.pid ended

I installed hostname

pacman -S inetutils

But that didn’t solve it either and I had to do this to fix it

rm -rf /var/lib/mysql/*
mysql_install_db --user=mysql --basedir=/usr

This removes the databases and creates a new copy. For me it wasn’t an issue as this is a fresh install but you should be careful when upgrading mysql. Its always handy to back up the databases first.
