Cat is one of the most well know commands of the Linux as well as of Unix systems. It’s mainly use to display the file contents of a small file on the terminal. But scope of the cat commands is not just limited to display, We can use the cat command to create,append and even in the concatenation of the two files. In this post we will learn how to complete these jobs using the same cat command.

I've been recommending Asus computers to friends and clients for some time now. After my recent dealing with the Asus support/repair center I will continue to recommend them for the foreseeable future.

July saw the release of KDE SC 4.7. Like all recent KDE releases, this is a combination of updates to the bundled applications, underlying desktop and associated technologies. Canonical have already pushed 4.7 through to Kubuntu desktops. If you are a 4.6 user who has just upgraded, don’t expect to be aware of major changes the first time you reboot. Some of the core applications have been updated, but most of the work has gone into improving the underlying frameworks. The applications themselves have been shifted to a greater reliance on Akonadi, the PIM storage framework and NEPOMUK, the semantic information database.

Bringing up arguments like "it provides more clarity to contributors, a 'check point' to look at the legal situation and reassurance of legal status to users" or the already-debunked "but it is helps protect the copyrights and handling of disappearing contributors" doesn't convince me that contributors should sign away their code while running the risk TO GET SUED BY THE COMPANY THEY JUST GAVE THEIR CODE TO FOR WRITING IT IN THE FIRST PLACE.

For those that missed it, S2 Games has made their Heroes of Newerth title go free-to-play. No longer does it cost $30 USD to buy the game, but it's free, which is S2's attempt to expand the game's user-base.

After a short delay, Mesa 7.11 has been released. This is the user-space library for providing OpenGL support under Linux for the open-source Intel, ATI/AMD, and NVIDIA drivers, among other hardware and software-based drivers. The Mesa 7.11 release also offers updates to the Gallium3D driver architecture. Here is some of what you can expect to find on Mesa 7.11.

A few minutes ago, August 1st, The Document Foundation company announced the second maintenance release of the LibreOffice 3.4 open source office suite software for Linux, Windows and Macintosh platforms, bringing several bugfixes.

live.linuX-gamers.net is a Linux live distribution: “boot ‘n play”. The idea is for you to be able to carry a decent amount of high-quality Linux games with you where ever you go for purposes of demonstration, gaming or parties. Your computer will remain completely unchanged, as everything will run live.

It's all Hugh's fault. Linus was all set to release the final 3.0 kernel when Hugh Dickins showed up on the list with a little problem: occasionally a full copy of the kernel source tree fails because one of the files found therein vanishes temporarily. What followed was a determined bug-chasing exercise which demonstrates how subtle and tricky some of our core code has become. The problem has been found and squashed, but there may be more.

The purpose is to highlight the most important topics related to setting up ESX/ESXi monitoring as well as applications hosted within managed virtual machines (a MySQL database is used in this tutorial).

After 10 years of full-time linux use, I'm finally content with my newly-discovered ripping program. I can easily create high-quality and reduced-bitrate copies of my music for home and mobile-device listening using Asunder.

Free software evangelists take pride in spreading the news about freedom and open source. They inform those that still feel locked into the old software distribution systems. The days of computer users being bogged down with virus-infested, bloated, and locked down systems are quickly coming to an end.

So, given that the vast majority of users don't actually use an OS as anything more than a launchpad for their word processors, IM clients, games and web browsers, why has Linux failed to make any real impression in the desktop OS space? The problem, in a nut shell, is that the word processors, IM clients and games they use in Windows don't run in Linux. Linux has failed on the desktop because it can't be used to launch the applications everyday users are familiar with (and I don't count Wine or its various commercial incarnations as suitable for everyday users). This is where technologies like Flash, HTML5 and ChromeOS and GeckoOS, and to a lesser extent the variety of tablets that are available today, are starting to level the playing field.

I have recently received a comment on the post about Pardus Linux, which made me think a lot.

The question in comment was:

What is your best favorite KDE distro? Mageia, Pardus, Kubuntu, Mandriva, PC Linux OS, Mint KDE.... which? :) I will use your choice :) thanks too.

In this HowTo I will describe how to prepare a CentOS 6.0 server for OpenVZ. With OpenVZ you can create multiple Virtual Private Servers (VPS) on the same hardware, similar to Xen and the Linux Vserver project. OpenVZ is the open-source branch of Virtuozzo, a commercial virtualization solution used by many providers that offer virtual servers. The OpenVZ kernel patch is licensed under the GPL license, and the user-level tools are under the QPL license.

Procedure to keep in sync Xen 4.1.2-r(X) on Ubuntu Oneiric ( development branch) with tip of Xensource's xen-4.1-testing.hg stable mercurial tree follows bellow, which provides a flexible way to apply the most recent changesets instead of back porting them to Xen 4.1.1 having permanent concern regarding consistency of selected set of CSs.

Writing and running your first app with code executing on the CPU and the GPU

In the time of free wifi and free internet connections in every hotel, bar or cafe you should be sure your connections are secure. In some cases you can’t trust the connection but you need to go online and read some mails or share some documents. In this case some basic tools like SSH and Firefox can help you to build an secure connection to an known computer in the internet you can trust (for example your own root server).

Looks like Mozilla wants to do it all alone and go the whole vertical. From browsers to version games and now looks poised to play Operating Systems giantsMicrosoft and Google Chrome at their own game. That both Microsoft and Chrome have had far too many battles is indeed to Mozilla advantage,
