Linux is not an operating system

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. Continue reading

Encrypted home in Ubuntu 8.10

This article is like a third edition to “Encrypted home in Ubuntu (or Kubuntu… or Debian…)”, although I keep changing the name. It’s the 8.10 edition. Many things changed and I updated the article for those, and the rest should work as well.

Motivation

Every day we put more and more personal information on our computers, and our computers become lighter, smaller, more mobile. In other words, the importance of the information gets higher and the possibility of being loosed or stolen gets higher as well.

Encrypted home in Ubuntu (or Kubuntu… or Xubuntu…)

This article is like a second edition to Encrypted home in Ubuntu (or Kubuntu… or Debian…). Important changes include that I have tested it for Ubuntu 7.04 Feisty Fawn and it works, but the devices are sd instead of hd due to all hard disk being viewed as SCSI (I am not sure why). Also I corrected some text layout problems of the previous article and I am no longer targeting Debian. Since Debian 4.0 Etch encrypting the whole file system (but /boot) is trivial because it is supported on the install, so you are not likely going to need this. Also, it seems more and more Ubuntu is taking a different direction than Debian so we may start to find big differences and I am not going to test this on Debian. Continue reading

Encrypted home in Ubuntu (or Kubuntu… or Debian…)

The explanations you’ll find here have been tested with Ubuntu 6.10 (Edgy Eft) and Kubuntu 6.10 (Edgy Eft), they should work without any problem in other members of the Ubuntu family and with minimal changes in other Debian-based distributions like Debian itself or Mepis. In other distributions it might require even more changes.

The lambda revolution, Episode V, the deb strikes back

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.

Cleaning up a Debian GNU/Linux (or Ubuntu), reprise

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!).
