(Dennis MacAlistair Ritchie)dmr - Dennis MacAlistair Ritchie silently left this world on October 12, 2011. Internet fraternity came to know about this sad news through Rob Pike's google+ status. Though, people were still overwhelmed by the Steve-mourning phenomena on different social networking sites. dmr has left a strong and unavoidable legacy of UNIX and C.

After more than two and a half years, very abruptly I am back to the Blogger dashboard. The Dussera holiday began with the hot saffron flavored Jalebies however, there were a sad news of the demise of Steve Jobs.Coincidentally, these days I am reading iWoz by Steve Wozniak and Gina Smith a late-birthday gift by a student turned friend turned colleague Prof. Devji Chhanga.This text reminded me of

It has been unanimously agreed that Computational Grids are proven tool for complex and resource consuming computational challenges. It is evident that these challenges need not to be a routine laboratory experiment always.Today's one of the similar challenge for the human race is to fight against the pandemic Swine Flue or Influenza H1N1.

Though the newer versions of Linux come with a GUI configuration utility (A NetworkManagerApplet) to configure a USB compatible phone to connect to the Internet still, in many contemporary as well as older versions do not have a graphical utility. So, in this post we try to tweak a USB phone by connecting it to the Internet. The Major part of this how-to is inspired from Dave's Blog (http://

Freinds, this time we are talking on something else and no linux, no PI, no supercomputing.On March 19, 2008 around 5.20 pm IST, (GMT +5.5) the orkut server suddenly seemed to have started a double bonanza offer and the number of scaps and fans was doubled. However, this lasted for only 10 minutes and hats off to the google people as the problem was resolved !! Can't beleive?? See the following

It's a very obvious practice to burn the downloaded iso images of linux (in general sense any operating systems) prior to the installation to an optical removable media (CD/DVD). However, for a change we will see how we can install a new linux distribution from an existing linux distribution and without making any copies of iso image of the operating system on a CD/DVD. There are some

Once again we have decided to play with the mysterious ∏. However, this time rather than just merely talk about this mysterious figure we will be implementing a simple algorithm to find an approximate value of the same. The said method as follows:Inscribe a circle in a square Randomly generate points in the square Determine the number of points in the square that are also in the circleLet n be

Most of the Linux users who are using multiple operating systems installations in a single hard drive. Many of them (Especially those of Microsoft's) have to encounter the erasure and re-writing of MBR (Master Boot Record) after re-installing or fresh installing Windows after Linux. This situation is very frustating as despite the Linux partition being intact, one has to reinstall the Linux

The list was published during at the International Supercomputing Conference (ISC ’07) in Dresden, Germany (http://www.supercomp.de) on June 27, 2007.

Continuous implementations in microprocessor and semiconductor technology, interconnections and relatively the never failing Moore's law have always hiked the pick performance of a Supercomputer year by year.

This post in our blog may seem to be slight different from the previous ones. As it concerns with more to social issue rather than the technical ones. Although the Free and Open Source Software has always direct concerns with the society, more specifically liberalised and free society.

The April month of this year proved to be the a milestone in releases of various popular GNU/Linux distros. It started with the release of longly awaited Debian 4.0 (aka Debian etch) http://www.debian.org/releases/stable/ on April 8, 2007. Then there was the turn of CentOS 5.0 http://www.centos.org/ and finally Ubuntu 7.04 (aka Feisty Fawn) http://www.ubuntu.com/ was released on April 19, 2007.

Everyone knows that Linpack (http://www.netlib.org/linpack/) is the de-facto standard for benchmarking a multiecomputer's performance under load conditions caused by complex mathematical computations. Even the official high performance measuring project Top500 (http://www.top500.org) also uses Linpack itself as a yardstick of high performance computing measurement. I also tested and benchmarked

Many times it has been observed that people just refuse to be migrated towards the Free/Open Source software on account of their "so called" less user friendlienss and non portability. Further, it is repeatedly stated that the free software does not fulfill a person's exact requirement.However, in real sense, this is quite opposite as Newton's III'd law!!
