For the purpose of writing this article I’m going to use the following definition of “operating system”. There are other definitions and I’m not claiming this is the right one. An operating system is a unit of software that you can install in a computer and will let you use the computer, thought a set of utilities or program in one way or another. (more…)

There’s an excellent article by Don “dons” Stewart called The lambda revolution which explains how to build a Haskell library in way that it is easy to download, compile, install, test, distribute, etc. I believe all those qualities are essential for successfully software. The next logicall step is to make OS-specific packages of it and since today I’ve had a short talk with Ian “Iglo” Lynagh, maintainer of many Haskell packages on Debian, who dissipated all my doubts about how to build a deb package of a Haskell library. Armed with that knowledge I am going to turn Don’s dlist into a beautiful deb package for Debian, Kubuntu or any other deb based operating system and tell you how.

My little article Cleaning up a Debian GNU/Linux was published at Debian Administration where lot’s of people replied with other ways to achieve the same goals. It was very nice to see all the different approaches with all the different pros and cons.
In the end I ended up changing my own approach for one that is faster and cleaner so I wanted to share it with you. Still, go to the Debian Administration version of the article and read the comments, they are very cool (thanks to all those who posted!).

You arrive at a Linux server which has some history of neglect. Let’s suppose someone else neglected it but if your new-year resolution is to stop neglecting your beloved server, this applies as well.
One form of neglect is to install, install, install and never un-install any package. The common utility to perform installation and un-installation of packages is apt-get which adds to the problem because it doesn’t have automatic removal of non-needed dependences.
PHP and ton of other packages. phpMyAdmin was removed when it was no longer needed but Apache, PHP and the ton of packages remain there.
Aptitude to the rescue. Aptitude is another package manager front-end like apt-get but it can keep track of automatically and non-automatically installed packages. That means that when you installed phpMyAdmin it was marked as non-auto while Apache and company was marked as auto. When you remove phpMyAdmin all the non-needed automatically installed packages like Apache would be removed.

This tutorial shows you how to configure BIND9 DNS server to serve an internal network and a external network at the same time with different set of information. To accomplish that goal, a new feature of BIND9 called view is used. As a tutorial it’ll walk you through the whole set up, but initial knowledge of BIND and DNS is required, there are plenty of documents that cover that information on the Internet.
