Tags: linux, ubuntu •
Comments: 4 This document describes how to upgrade from Ubuntu 12.04 to Ubuntu 14.04 LTS. Generally, the Ubuntu .04 versions that get released every 2 years are Long Term Support (LTS) releases, for instance Ubuntu 12.04, 14.04 etc. Effectively, this means that the LTS release comes supported with bug fixes and security updates for as long as 5 years, hence users would not have the privilege of being alerted through popups urging them to install the latest available version.

Linux Quota - installation and configuration on Ubuntu and Debian
Author: Gurujyot_singh •
Tags: linux, debian, ubuntu •
Comments: 5 Quota allows you to specify limits on two aspects of disk storage: the number of inodes a user or a group of users may possess; and the number of disk blocks that may be allocated to a user or a group of users. The idea behind quota is that users are forced to stay under their disk consumption limit, taking away their ability to consume unlimited disk space on a system. Quota is handled on a per user, per file system basis. If there is more than one file system which a user is expected to create files, then quota must be set for each file system separately. Various tools are available for you to administer and automate quota policies on your system.
