The Linux Game Box


Linux is well known as a poor platform for the hardcore video game user. If you look for the video game market hits you won't find them running under Linux. For that you'd better choose a PC or mostly a last generation game console such as Xbox360, PS3 or the more niche oriented one Nintendo Wii.

The Linux game panorama is not completely bare though. Just for this I want to start this new column to periodically present one Linux game I installed and played with my laptop. The use of a laptop takes a specific role here. Having said that Linux is -at the moment- completely alien to the massively marketed and leading technology games, then to play games on Linux which are playable and enjoyable on a honest average laptop it's something lots of people can be interested in. We're not speaking of a game oriented machine but something that you more likely already use for work or in school.

The machine I will play the games to review is the following:

Packard Bell EasyNote (2005)
Graphic card: Ati Mobility Radeon X1600
CPU: Centrino Duo T2300
RAM: 1Gb
OS: Ubuntu 8.04 Hardy Heron

So, I will periodically look for one game (I already have a bunch of them noted down in tomboy) install it and play it. Then I will write something like a draft review (nothing like an IGN behemot) in this column. I will give my opinion on the basis of the following aspects:

- Installation pain
- Gameplay fun
- Graphical appeal
- Sound delight
- Story enchantment

The choice of the games is completely biased. At first I will start from games do have an appeal to me and then move on from those. Of course you can let me know your suggestions.

I do hope with this work to help sharing the know how of the Linux free and open source (and commercial maybe) scenario as well as paying tribute to those teams of enthusiasts who do such a great job and supply us Linux lovers with wonderful games.

The first review is about AstroMenace so stay tuned folks!

Sightseeing Italy's major cities with Google Street View

On October 29th Google Maps Street View hit three Italian major cities plus the area around Como lake in the northern part of the country.
You can now go and have a stroll down Milan, Rome or Florence streets or the romantic coastline of the Como lake.

Google Maps Street View (together with the other geo apps like Google Earth) is the sightseeing killer application as it gives you the chance to visit places you've always dreamt to go but, for a reason or another, never managed to fulfill. As GMSV expand in coverage and quality the world gets shrinking and shrinking. These geographic apps make me think of the rift information technologies creates between what once were (and by most educators still are) the regular education tools and the resources that are available nowadays, easily and free. Just think of Google Earth, we X-Generation guys and girls used to see something like this (much more rudimentary though) in 80' movies or comics. These systems were usually pictures of high level military resources. Nowadays we used satellite maps to spot our pic-nic place!

Have I already said that I totally confide in technology (and especially in free open source software and open source hardware) for a better world?

The Linux road to heaven

One article by Ed Bott on Zdnet made me think of how Linux enthusiast often underestimate the complexity of the scenario regarding Linux based systems market share and penetration.
Bott reported MSI concerns about their Linux based machines which, they state, suffer from a higher return rate (up to 4 times) from end users than windows based machines. They say they will stick to their effort to manufacture and sell Linux laptops but disclose the problems they must face in offering such machines to the desktop public (e.g. higher costs for software development and support, especially when we speak of low price sub notebooks like those of their Wind line). I can accept this complaint as a general one but in the specific I wonder why the huge success of similar products (Asus EEE PC for one) occurred despite the problems MSI disclosed.
Bott admits he writes about Windows for a living and though we can judge his opinion as biased and MSI example as poorly relevant one, but this is not the point and not certainly the object of my thought.
Up to today there's no competition in the OS market shares, except for an ongoing insurrection from the part of OSX. With OSX we'd better speak of system ascent, but I bet the share of Linux distros altogether is nothing more than a tiny biodiversity in the personal computers world ecosystem. I say this without a solid statistic base given that I haven't really found any statistics I'm comfortable with on the web.
Focusing on the desktop environment and considering the most spread distros I am more than conscious that Linux is a valuable alternative to Microsoft Windows. From the day I migrated to Ubuntu I've always done my best to convert friends and colleagues to a Linux distro. Sometimes I even got close to it. I never succeeded though.
I share Bott's opinion when he talks about habits. Men stick to their habits and they're not prone to invest time end energy in trying different things, especially when these things aren't always full interchangeable. From the many problems which prevent Linux to penetrate the mainstream market I think this is the most relevant one. Microsoft is a colossus and despite all the attacks it suffers from geeks it has indeed been able to create and promote a system in such a massive way that nowadays the mass of people just consider Windows as a standard. More of that, they believe it's a standard! For those people it's just inconceivable to have a PC running an operating system different to the one they're used to see and use. Sometimes when I enthusiastically speak of all the wonders and advantages (which are far from few and irrelevant) of a Linux system to people, they just listen to me with that attitude which says "yes, they also say you can receive broadcast tv with your screw driver"... That's enervating but it's just a normal reaction.
So, how could Linux improve its market share?
Well, I'm no business guru but I have some points about this issue. There are three marketing tricks which I think might give the market a little shake.
First: Focus the target.
Many distros have made (and are constantly making) giant leaps as desktop environment solutions. This is precisely why I took the decision to wipe out XP from my laptop and install Ubuntu. Despite these improvements Linux needs to strike those places where people are obliged to use a system which had been already chosen for them. With this I mean the work places. Let's take Canonical as reference for our example. Say that Canonical propels LUGS or member of LUGS to start an activity to promote Ubuntu distro. Activities could be scheduled to propose small, medium sized and even large companies (in particular those belonging to the public administration) to consider the Linux distro when the desktop stations renewal is scheduled.
Second: Strike carefully
When carefully proposed, with a rational set of elements -an assertive mood and a clear presentation- there are strong reasons for such target companies to switch partially or fully to one Linux based distro. A partially switch is especially advisable as target because it permits to focus on a specific business sector more prone to be converted to Linux. Thinking of the company where I work, I found it difficult to imagine a sudden switch to say Ubuntu in the engineering department where there are mass investments on software running under XP. On the contrary it could be more convenient to convert the machines running in other departments such as administration, planning, warehouse, production, quality, to Linux. In my company the main problem would certainly be the management tool which is commonly used by all these departments and run under XP. Nevertheless a long time schedule conversion to Linux to such kind of departments can indeed offer strong advantages which are so much relevant for an organization to result in money saving and work flow improvement. Let aside the money aspect, two of the basic problems affecting the average company computer network are instability issues and system damages caused by viruses. Many people are illiterate when concerning even the basic aspects of information technology. I personally assisted to a warehouse man who wrongly typed DHL URL and when a nice gurl showed up with the sentence "click me" on her boobs, guess what he did?
Third: Development and development
Big things come out of small things. How can we seriously expect a big company involved in big projects requiring huge investments spread on a pipeline of hundreds of people to release a version of their best seller software for a platform which is to their eyes sterile? In this I strongly agree with those who say that commercial software isn't necessarily evil. Some forms of exploitation of commercial software or some commercial practices are. For this reason the promotion to those small workshops which can produce and release innovative and quality software for Linux is much important. Take games for example. I'm motivated to think that a strongly engaged and highly skilled team of independent people can realise games that are at least for some aspect comparable to the million dollars productions that bust the market nowadays. Don't forget that such a small team would work under completely different organisational and money constraints, especially when the team represent a start up entity for the members. Linux game scenario is today rich of high quality and completely free and open source games being developed by communities of enthusiasts whose main aim is no other than to see their game to grow and flourish. Free tools are also there to help this process. We have Blender which is a 3D modelling tool comparable to the professional ones used in "serious" game productions. Blender is also equipped with an integrated game engine, and we even have more powerful engines like Ogre3D, Crystal Space, and Panda3D which is maintained and used in Disney's commercial game products.
Linux is a great operating system with big capabilities and a vast community of supporters. I do believe that Linux in general is really one tool that can help improve the world we are living in. We just need to be more focused and less dispersive. I know that dispersion is one of the main characteristics of Linux, as highlighted by the multitude of distros, but I'm truly convinced that the success of our cause will pass through unity.
Ubuntu success in achieving a vast public knowledge is there just to witness this concept.

Mac-flavored two-fingers scroll for any Linux touchpad

'm speaking to you, proud possessor of a Ubuntu based laptop. Have you ever been mocked by your Mac pal ‘cause she/he could scroll web pages with an elegant and trendy two-fingered movement on the touchpad? Well, I have just discovered that the same advanced Mac feature is present on the vast majority of the Synaptics touchpads.
My good friend Carlo, of the Italian technology podcast Tecnica Arcana, posted a quick tutorial, in Italian, on his blog Court of Misanthropy. By reading it I've noticed that it's pretty simple to apply the modification needed to activate the two fingers scroll feature. I've followed the tutorial which worked perfectly. I must admit that now when I scroll pages with two fingers my touchpad behaves quite weirdly. Often the page leaps forward of a big amount of lines. Then when the scroll reaches the end of the page it's impossible to scroll up with the two finger gesture because when doing so the page keeps bouncing backwards. By the way this issue is likely to be related to my own touchpad model or to some other configuration. My friend Carlo and other people who followed his tutorial have found no problem with this feature.
Let's start the quick guide. You basically need to add a few lines to your xorg.conf file and install a controller from the repositories. I've done this tutorial on my Packard Bell laptop with distro Ubuntu 8.04 Hardy Heron.
1- let's backup xorg.conf
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.copy
2- open xorg.conf
sudo gedit /etc/X11/xorg.conf
3- go to the section "input synaptics" and add the following three lines at the end of the section (just before "end section")
Option "SHMConfig" "on"
Option "VertTwoFingerScroll" "true"
Option "HorizTwoFingerScroll" "true"
The section will resemble something like this
Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "HorizEdgeScroll" "0"
Option "SHMConfig" "on"
Option "VertTwoFingerScroll" "true"
Option "HorizTwoFingerScroll" "true"
EndSection
4- install gsynaptics from the repositories (you will then found it under system/preferences).

gsynaptics is an application which allow you to adjust the setting for your touchpad. You can also enable the single finger and two fingers tapping which respectively recreate the left mouse button and the press of the mouse scroll wheel (it opens a new tab in firefox)
5- reload X with ctrl+alt+backspace (or restart the system)
If you are an Italian speaker you can watch a youtube video tutorial on Carlo's blog. More than this I strongly recommend you to listen to Tecnica Arcana podcast which is a simply outstanding podcast rich of interesting technological discussion.
Let me know if you found this guide useful!
