ssd on ubuntu

i've got new notebook with ssd on it. so right after fresh ubuntu install had to tweak it to save ssd from worn out.
had to google out tweaks and since i'm doing this second time here is just a relevant link and steps

1. disable swap http://help.ubuntu.ru/wiki/ssd
2. adjust sysctl params
3. adjust ext4 params
3. disable chrome cache http://ubuntuforums.org/showthread.php?t=1277711
