This is the second part of my article on my favorite games released for Linux in 2013, this is the list of my personal top 10.

10 Knight of pen and paper +1
9 Shank 2
8 FTL – Faster than Light
7 Defender’s Quest – Valley of the Forgotten
6 Trine 2
5 Legend of Grimrock
4 Dungeons of Dredmor
3 Don’t Starve
2 Let 4 dead 2
1 Crusader Kings II

As you can see from this list I like strategy games and RPGs, but in this list there are also other genres, you will find a description of the games from position 10 to 6 in the first part of this article.

You can find all of these games on Steam, and most of them are available at a discounted price on The Humble Store, I suggest to take a look at both websites as in these days they are doing big sales on these titles with discounts from 25 up to 75% of the listed price.

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.

The sysadvent blog it’s up and running again. In this period of the year you’ll find there 1 great post every day, so keep it in your bookmarks !

This was written by Michael Stahnke last year, but it’s till good to me.

It’s happened. The DevOps term has been picked up by everybody and their brother. From analysts, to marketing firms, to recruiters, the term is everywhere. Beyond it being a very loud echo chamber, it sparks debate. I see tweets and complaints all over the blogosphere about how hiring a ‘DevOps’ team, or being a ‘DevOps’ isn’t the proper adoption of this methodology. That may be true, but arguing about it seems to only be a net-loss from the collective brain-power reading and responding to said internet ramblings rather than solving difficult systems problems.

The push has been largely around culture. DevOps is culture. I’ll agree with that, but it’s not just being rockstar-ninja-superheros operating at web-scale.

I’ll pick up my story in 2007. I had just moved to a new state, new team, new role as a system administrator (mostly doing Unix/Linux). This move was at the exact same company I had worked at since 2002. This move wasn’t a promotion. The Unix team, a seven person team, had had five amazing system admins quit in span of about 60 days. On paper, me taking this job sounded like a horrible idea, so why was it interesting to me? Unlike the rest of $Company, this business unit did things a little bit differently. For some reason, they purchased hardware not on the approved list. They let you run Linux on your desktop. However, the thing that was most interesting to me was the software stack: they ran on Open Source. The most profitable business unit in $Company ran huge amounts of open source software! It was awesome. Rather than drowning in Tivoli, HP, CA and BMC system tools, they had tooling set up with nagios, irc, subversion, cfengine, trac and copious amounts of perl.

This spoke a bit about the culture of the business unit IT department.

vagrantIf you work in IT it’s pretty normal in these days to have a computer with at least 4GB of RAM and if you have bought it in the last year probably it has 8GB, this is fantastic to run modern applications that usually require much more RAM than in the past, but this make the use of Virtual Machine on personal computer much more easy and doable.

This open some interesting options in the development cycle of any application or service as now it’s possible to have a development/test machine on every personal computer, as system administrator I’d like that these VM should be as much similar as possible to the production environment, so what’s a good way to manage and distribute Virtual Machines to the developers ?

For what I’ve found around the best answer at the moment it’s: Vagrant.
In this first part I’ll cover the theorical aspect of Vagrant and in the next one I’ll show you some basic command to setup a running environment with it.

Screencloud is an app that allows you to capture screen under Linux , Mac or Windows and automatically upload the screenshot to an FTP/SFTP server of your choice or a provider in the cloud such as Dropbox, Ubuntu One, Imgur or a cloud service proposed by Screencloud themselves.

Once the file is sent, your clipboard will contain the link to the image.
This could be a good way to quickly share a screen capture without having to do the multiple steps (take/save/change it/upload somewhere/copy the url) that usually you should do to share a simple image.

The software is released under GPL-2.0 and the sources are on github.
