Linux Game: Legend of Grimrock

Jan 012013

I’ve bought Humble Bundle 7 (still available for 24 hours) and a big positive surprise of this bundle has been Legend of Grimrock.
This is a classic RPG game, you’ll have the control of 4 characters that you can choose between 4 races and 3 classes with these “heroes” you’ll have to walk in a dark dungeon searching to regain your freedom.

The game it’s a slow paced real time RPG, where you have to use your wits and intelligence much more than the muscles of your 4 Heroes, the graphics is really well done and i suggest to play it during night time or without strong lights to have a great game experience.

1 week with Mint Nadia XFCE

On the 21 of December Linux Mint 14 Xfce has been released, codename Nadia.
This release of Mint is based on Ubuntu 12.10 and shipped with the XFCE desktop environemnt as my readers probably know I’ve installed Mint 13 XFCE on my new desktop and so I’ve decided to upgrade my installation to this new release.

As first thing, do I suggest to upgrade to this release ?
Yes and no, Mint 13 is based on Ubuntu 12.04 that is a Long Term Support distribution, this means that like other LTS releases 12.04 will have updates for 3 years, and will include point releases that bundle updates to shorten downloads for users installing the release later in its lifecycle. The point releases and dates are: 12.04.1 (23 August 2012), 12.04.2 (31 January 2013), 12.04.3 (15 August 2013) and 12.04.4 (24 January 2014). There are no further point releases scheduled after the release of Ubuntu 14.04 LTS.

So if you are happy with your software and all your hardware works you have no strong reasons to do this.

On the other hand, if like me you have a D-LINK N 150 aka DWA-125 or some other hardware that don’t work perfectly with your Kernel an update could help you, spoiler: This upgrade helped me in removing all the proprietary drivers in my installation.

Configuring 2 mirrored disks on Ubuntu Linux

Dec 282012

I’ve just recovered 2x 500 GB sata disks from an old installation, so I opened up my new Desktop and connected them to my main Linux machine, these 2 disks have been used for around 3 years on the the other installation, so I prefer to use them in a mirrored configuration, or RAID 1, so everything that is wrote on a disk is copyed automatically also on the the other, and there is no loss of information if 1 of 2 disks broke up.

At the moment I use a Mint 14 XFCE edition, that is totally compatible with Ubuntu 12.10, and in my point of view for some aspects much better, so in this guide I’ll use commands that are compatible for Mint , Ubuntu and Debian, for other distributions you’ll have to search for your packages, but the configurations and commands will be the same.

An introduction to security models in Linux

Today I’m glad to republish an interesting article of Adrian Stolarski first published on Infosec, a great source of information about security.
It’s a good summary of the different type of security models that you can have in a Linux system, focused on SELinux, and if you are interested in this topic, be sure to take a look also at my Introduction to AppArmor

A task of any operating system is to provide software that strongly increases its security. A lot of programs of this type have been created; some are better than others. What does it look like in terms of Linux? Of course, here we have many more choices when it comes to this type of software, but some software is worth recommending. Some people already know what I mean: SELinux. Why choose this solution? Why do I think it is so different from other software of this type? And the last key question: who really should use it?

This system, as the name suggests is Security Enhanced Linux! So I invite you to read this article and learn about this tool.
