RAID stands for Redundant Array of Inexpensive Disks, is a process of using multiple hard drives to replicate data. There are different kinds of Raids such as :
Raid 0 stripped set, Raid 1 mirrored set, Raid 5 stripped set with parity and so on. (Source: Wikipedia).
Here is a very cool way of understanding RAID as explained by an enterprising mind. And when I say cool, I mean it.
I recently read a news item which disclosed that Microsoft plans to incorporate anti-piracy technology into the yet to be released Vista OS. This set me thinking. What does this hold for GNU/Linux? Put differently, could this move by Microsoft have any positive effect on the popularity of GNU/Linux ?
Before we jump into talking about Linux and what it stands to gain from this, let us look at the
Apache is one of the most popular web server which is stable and which scales very well. This web server which has been released under a free licence has the honor of powering many of the very high traffic sites, not to speak of the 100s of 1000s of ordinary websites dotting the net landscape.
Usually, when you host a website on a shared server, you are not provided any rights or access to modify
When ever I get to take apart a gadget and look inside, I can’t help but stare in wonder at its working. This is especially true when the said device consists of some moving parts. Sometimes I can’t help thinking that we humans should pick up a thing or two from the gadgets – especially the team work bit. All the small pieces of the gadget come together and work as a single entity – each doing its
Quite often, we speculate about Linux grabbing a major share of the desktop PC market. But it seems the film industry are heavy users of Linux, and applications that run on Linux which include both open source and closed source custom made software. Take the popular hollywood movie ‘Scooby Doo’ for instance. It was created at Rhythm and Hues studio and the whole movie was rendered and touched up
All netizens would by now be aware of Google re-launching its online Spreadsheet and Writely Document products as an integrated product at docs.google.com. This is a first look at what is in store for people who intend to use this Google product. What is interesting is that Google is on a fast trot to integrate all its online services by linking it with a single Google account and this latest
PC-BSD – the FreeBSD clone which was widely touted as the BSD for Desktop users have a new owner now. It has been acquired by iXsystems who are an enterprise-class hardware solution provider. In a previous article I had written my experiences in installing and using PC-BSD. One of its USPs is the click and install method of installing software akin to that found in Windows. Yet another feature is
Linux had always lacked a Open Source virtualisation technology in the same league as Solaris containers or commercial product like Vmware. That was until Xen came into the picture. Xen is an opensource virtual machine monitor for x86 that supports execution of multiple guest operating systems. Xen is released under the GPL and can easily be used to run virtually, OSes as diverse as different
Flash – the technology which allows one to build rich multimedia intensive, user interactive websites and applications was developed by the erstwile Macromedia – now acquired by Adobe. Flash is famed for its flexibility and ease of use in creating multimedia intensive web applications while keeping the size of the resulting application nominal. Lets face it. There is no way we can boycott Flash
Anybody who runs a website will be faced at one time or another to redesign his site. I have myself tried my hand at redesigning this site with varying degrees of success – though you can plainly see that there is a lot of scope for improvement.
But does designing websites require following a series of pre-charted steps ? Or is it a process which require little if any planning – one where you
When you hear the name Slackware, you are at once transported to a world where Linux users feel more at home in setting the configurations by editing ordinary text files. In fact the credo of Slackware is to keep it as simple as possible. In popular speak, it is known by the acronym KISS (Keep It Simple Stupid). When I use the word simple, I mean simple in relation to a person who is already well
PHP, one of the most popular server side scripting languages has become the de facto standard in developing many of the high traffic websites around the world. Not surprisingly, many projects have grown around this language which aids the web developer to integrate more and more third party products by way of maps, imaging applications and more into the website. Flickr is one of the most popular
Firefox ver 2.0 was released a few days back and naturally it is loaded with a host of new features some of them prominent and many more rather subtle. I found this new version to be a huge improvement from the older 1.5.x version which is bundled with most Linux distributions. These are some of the new features in ver 2.0 of Firefox which I found really interesting.

In recent times, if you ask me to name one personality in the free software community who has been as much reviled as being adored, I would say it is Richard M Stallman – the father of GNU. He has been bashed in the media as much for his dedication towards furthering the cause of free software and his firm stand against DRM. I believe that if not for GNU and GPL, the Linux movement would have
In a previous post, I had written about the features of MythTV and listed a number of MythTV sites which provide help in installing MythTV and configuring it to work on ones machine. MythTV is a GPLed software which allows one to watch TV on ones computer. It has capability to intelligently detect commercials in the TV programs and skip through them. The result is an advertisement free program for
There was a time when publishing content online required fairly good technical knowledge even when the data resided in static HTML pages. Then the blogging revolution happened and the rest as they say is history. Now a days it is possible to publish content online even without an iota of knowledge about the HTML elements. The person writing the article can free his mind to fully concentrate on

Consider this scenario… You are interested in installing GNU/Linux on your machine. Assuming you already have the latest version burned on to a CD, it is a simple affair of popping the CD into your CD drive and starting the instalation. But once the installation is done and finished, you will most certainly want to install additional software apart from the ones bundled with the CD. And if you
NC – short form for Netcat is a very useful tool available on all Posix OSes which allow one to transfer data across the network via TCP/UDP with ease. The principle is simple… There is a server mode and a client mode. You run the netcat tool as a server listening to a particular port on the machine which sends the data and you use netcat as a client connecting to that particular port on the
At a time when I was using Red Hat (Fedora), One of my favourite repositories was Dag-wieers not only because the official Red Hat repository was dead slow due to excess traffic but also because dag-wieers contained a number of additional RPM packages which were missing in the official repositories such as those with support for proprietary file formats. That was the culmination of my search for
I recently got hold of a very nice book on Ubuntu called Ubuntu Hacks co-authored by three authors – Kyle Rankin, Jonathan Oxer and Bill Childers. This is the latest of the hack series of books published by O’Reilly. They have made available a rough cut version of the book online ahead of schedule which was how I got hold of the book but as of now you can also buy the book in print. Put in a
Yesterday, I received a strange mail in my mail box. The strangeness was related to the fact that the site in question (reviewme.com) invited bloggers to review products and publish it on their blogs for which reviewme.com paid them money depending on various factors such as site popularity and traffic.

The panel composed of distinguished personalities including Steve Ballmer – the CEO of Microsoft, N.R. Narayana Murthy – Chairman of Infosys Technologies, Ashok
A few months back, I had posted an article related to BIOS which described its functions. A BIOS is an acronym for Basic Input Output System and is the starting point of the boot process in your computer. But one of the disadvantages of the proprietary BIOS which are embedded in most PCs is that there is a good amount of code which is used in it to support legacy operating systems such as DOS
ifconfig – the ubiquitous command bundled with any Unix/Linux OS is used to setup any/all the network interfaces such as ethernet, wireless, modem and so on that are connected to your computer. ifconfig command provides a wealth of knowledge to any person who takes the time to look at its output. Commonly, the ifconfig command is used for the following tasks:

Ever wonder how a CD aka Compact disc is manufactured? There is a whole string of tasks involved in creating the compact disc. It starts by creating an original master disc made of glass. During the process, the glass disc is treated with two chemicals – a primer and a photo resistant coating. Then the photo resistant coating on the glass surface is dried in an oven for 30 minutes. Then the data
With the speed with which advances are made on the technological front, I sometimes wonder if buying an electronic product now is a good decision. Especially since if I choose to wait for a couple more months, I could get an even better product with more features at more or less the same price as the product I intended to buy now. This truism is especially valid while buying a PC. On the one hand,

Anybody who has played games on their PC will be familiar with a classic game called Breakout where you have to bounce a ball with a paddle and smash all the bricks. While this game in its original make does not sport any special features, it has helped spawn a number of breakout clones which provide additional special effects such as power-ups that provide more power to the ball for a short while
We are moving towards an era where the line demarcating a computer and the rest of the electronic devices is at best getting hazy. Take the mobile phones for instance… Now a days, the sheer power and the number of features available in some models of mobile phones rivals those found in a low end PC. Electronic devices are fast morphing into gadgets which are many things for different
