An interesting and detailed howto on apt, first posted on linux mint community tutorials

Intro by Wikipedia:

The Advanced Packaging Tool, or APT, is a free user interface that works with core libraries to handle the installation and removal of software on the Debian GNU/Linux distribution and its variants.

Today I present an interesting aritcle on Bad Blocks, first published on http://virtualprivateserver.castlegem.co.uk/

Hardware fails, that is a fact. Nowadays, hard drives are rather reliable, but nevertheless every now and then we will see drives failing or at least having hiccups. Using smartcl/smartd to monitor disks is a good thing, below we will discuss how some lesser issues can be handled without actually having to reboot the system – it is still up to a sys admin’s own discretion to judge circumstances correctly and evaluate whether disk errors encountered are a one time incident or indicative of an entirely failing disk.

citadel

I was searching for lightweight collaboration suite (messaging and groupware) to manage some small websites and while searching around I found Citadel.

Citadel is a complete and feature-rich open source groupware platform.

  • Email, calendaring/scheduling, address books
  • Bulletin boards, mailing list server, instant messaging
  • Multiple domain support
  • An intuitive, attractive AJAX-style web interface

The Citadel system is extremely versatile. It provides numerous front ends to present to users, such as a text-based interface, an AJAX-style web interface, and many popular PIM clients using SMTP/POP/IMAP. All of these can be used simultaneously.

It’s also extremely scalable. Not only can a well-equipped Citadel server support a large number of concurrent users, but you can also build a distributed network of Citadel nodes that share rooms and their content.

Let’s see how to install and configure it on a Debian 7 “wheezy”, most of this guide it’s based on the great linode guide wrote for debian 6.
