Some popular Racing Games available for Ubuntu/Linux

Although, a number of racing games are available but Here is the collection of my Top 3 – favorite racing games that I like to play on Ubuntu (11.10), All are open source and available freely in Software Center. If you have more experience in gaming on Linux desktop then feel free to share your experience (through comment).

1. Trigger Rally : 3D Car Racing Game


Trigger Rally is a fast open source racing game for Linux users. It is a lightweight game and very easy to play. Although, the number of tracks and vehicles available in the game (by default) may  not be sufficient for some users but it’s not difficult to add a new one. The game is based on OpenGL.

Want to try the Game ? First watch this video –

Install Trigger Rally in Ubuntu 11.10/12.04

Open a terminal and execute –

sudo apt-get install trigger-rally


Torcs - racing game

TORCS is an open source 3D racing car simulator game. it uses Open Graphics Library (OpenGL) so you may need a graphics card to play this kind of games on ubuntu. TORCS is one of the most popular racing game for Linux users, that’s why it has been included in Ubuntu package Repository by deafult – so if you want to install the game then just go to Ubuntu Software Center, search for torcs and install! Or execute –

sudo apt-get install torcs

3. SuperTuxKart


Supertuxkart  is a cart Racing game – forked from Tux Kart game. It is one of the most funniest games available for Ubuntu – specially kids love this kind of game (warning!, it’s addictive too). A lot of ccol and funky characters, racing levels/modes makes it a n incredible racing game. To install this game – open a terminal (Ctrl+Alt+t) and execute the command (or you could also install it from Software Center or Synaptic Package Manager (it’s not there in Ubuntu 11.10, by default))

sudo apt-get install supertuxkart

That’s All! Have Fun 🙂


Batch png Optimizer for Ubuntu/Linux

PNG (Portable Network Graphics) is one of the most popular image format used over the web – most of the graphics designers uses png format for designing logo of a website or in computer artwork (because PNG is more suitable for computer generated images). Optimizing image is a good practice in modern web development/work because it will allow the pages to load much faster due to reduced image size. Google also recommends all web masters to use optimized images for faster loading of pages and you may already know that SPEED is one of the most important thing to consider while designing a website or a web application.

Now, you understand the importance of optimize image – but there should be a balance between the quality and the size of an image. Loss-less compression is what most people prefer while compressing/optimizing an image. On Linux based operating systems such as Ubuntu, Linux Mint, Fedora, OpenSuse, PCLinuxOS etc you can also use GIMP with save for web plugin to optimize png images (it also supports other popular image formats such as JPG, GIF etc).

GIMP (with image optimizer plugin) is good when you have few image but what you will do if you want to optimize hundreds of png files because because it doesn’t support batch optimization. That’s where the OptiPNG comes in, a great tool to optimize PNG image.


OptiPNG : Advanced PNG optimizer

OptiPNG is a an open source and cross-platform image compression/optimization tool. It supports batch processing i.e you can optimize bulk of png files in one simple command. It is very powerful application, as it provides you a lot of options such as compression level (1-7) where 1 is minimum and 7 is the maximum compression level. Page Speed (by Google Inc) – one of the most popular website optimization plugin/tool, uses OptiPNG for optimizing png files.

How to install OptiPNG

Ubuntu (11.10/12.04/12.10.. or Linux Mint, it should work with any Debian based distributions) users can install it by executing one simple command from terminal (Ctrl+Alt+t) –

sudo apt-get install optipng

Other user can download it from the official website. Primarily it’s a command line tool but front end for various platforms are also available, pretty useful if you don’t want to get your hands dirty with Terminal.

Optimizing Images using OptiPNG

To optimize image you can just give the file name as argument or specify compression level and other options. Just type optipng at terminal to see the help and options available for this tool.

For single image

optipng file_name.png

it will optimize the image and overrite the existing one, with default speed and compression level.

For Higher Compression (obviously the speed will decrease)

optipng -o7 file_name.png

Optimizing all png images of a directory (at higher compression level 7)

cd path_to_image_directory
optipng -o7 *.png

best graphics card for ubuntu 11.04/10.10

Ubuntu or any Linux based distribution has very bad history regarding the graphics card compatibility and performance (The reason is obvious, driver manufacturers do not provide driver softwares for their graphics card..), but in past few years I’ve noticed some nice changes and improvements which is worth acceptable. Since Ubuntu is the most popular desktop distribution, so now a days, it’s not a difficult task to find a good video card well compatible with Ubuntu 11.04 (Natty Narwhal) or 10.10 (Maverick Meerkat) or 10.04 LTS (alias : Lucid Lynx). Most of the graphics cards will be auto detected by Ubuntu (Just after the installation of Ubuntu 11.04/..).

In this post, you will learn how to select a graphics card for you Ubuntu computer, depending on your need and budget. If you are a normal users and think that I do not need any graphics card, then also you would probably have to purchase a graphics card because of the 3D effects of unity desktop (Although you can use classic desktop instead and turn off the compiz effects to go smoothly). By the way there are other advantages of using Graphics Card – such as better video quality (which in turn means that watching movies will be more Fun!), a lot of funky 3D effects, better system performance (due to dedicated video memory or GPU (Graphics Processing Unit)), and of course – good for video game players because you can play more games in better ways depending on the power of graphics card.

best open source graphics softwares

Open Source Softwares/Applications are now becoming the most appropriate choice for students,designers,programmers,developers and common desktop users, not only due to the reason that most of them are freely available but also due to the fact that – they can customize a open source software, in a better (due tis open nature i.e source code is open to all) way than a closed source(proprietary) software.

Open Source software and technology is specially helpful for beginners (May be a student or a startup (Think for a Minute, if you want to learn how to develop a web apps then(for some designing stuffs) would you like to invest thousands of dollars on Adobe Products(e.g Photoshop) or you will go for some FOSS(free and open source software) alternatives like GIMP) ) because it allows them to complete the task without compromising (sometimes a little might be accepted) with the quality at zero or negligible cost.

Linux based operating systems have a dominant position in web server market (Red Hat Rocks) and now they are approaching well (due to some user friendly Linux distributions like Ubuntu(10.04/10.10 or upcoming version 11.04) and Linux Mint(Latest Stable version -10-LMDE)) towards the desktop market. Most of the open source Applications are cross-platform(available for Linux based Distros,Windows & Mac OS X ) , some of them are very popular like Mozilla Firefox,VLC Player etc, while some are less popular on non Linux platforms.
