I really appreciate the fact that Ubuntu comes ready to use in multiple languages; the fact that Ubuntu and Linux in general serve an international community is one of my favorite things about the operating system. That being said, I don’t need a lot of the fonts that come in the basic install of Ubuntu, especially the ones with Arabic and Asian characters. While looking for a way to safely and easily remove these unneeded fonts in Ubuntu, I came across this thread at LaunchPad, advising the following command in a terminal: sudo apt-get remove ttf-kochi-mincho ttf-kochi-gothic ttf-arabeyes ttf-arphic-ukai ttf-arphic-uming ttf-baekmuk ttf-bengali-fonts ttf-devanagari-fonts ttf-gentium ttf-gujarati-fonts ttf-indic-fonts ttf-kannada-fonts ttf-kochi-gothic ttf-lao ttf-malayalam-fonts ttf-mgopen ttf-oriya-fonts ttf-punjabi-fonts ttf-tamil-fonts ttf-telugu-fonts ttf-thai-tlwg ttf-unfonts-core ttf-indic-fonts-core ttf-wqy-zenhei This worked excellently as a way to remove unneeded fonts in Ubu...

On Linux, you can setup disk quota using one of the following methods: * File system base disk quota allocation * User or group based disk quota allocation On the user or group based quota, following are three important factors to consider: * Hard limit – For example, if you specify 2GB as hard limit, user will not be able to create new files after 2GB * Soft limit – For example, if you specify 1GB as soft limit, user will get a warning message “disk quota exceeded”, once they reach 1GB limit. But, they’ll still be able to create new files until they reach the hard limit * Grace Period – For example, if you specify 10 days as a grace period, after user reach their hard limit, they would be allowed additional 10 days to create new files. In that time period, they should try to get back to the quota limit. 1. Enable quota check on filesystem First, you should specify which filesystem are allowed for quota check. Modify the /etc/fstab, and add the keyword usrquota and grpqu...
