New Applications on!!!

I enabled 7 applications on sometime back. They are not open source softwares, but freewares.

Here is the list of applications and what they do in brief

> ARMS: Spatial Alignment with the RMS (Root Mean Square) method. (fixed pairwise correspondence)
> ASV: Analytical calculation of van der Waals surfaces and volumes.
> CSR: The Combined SDM/RMS Algorithm for spatial alignment of two molecules. (pairwise correspondence computed)
> DOG: Docking Geometrically two molecules. (fixed pairwise correspondence)
> POP: Optimal Partition (classification). The number of classes is computed.
> QCM: Quantitative Chirality Measure of a conformer. (graph automorphisms enumeration included)
> RADI, RADI2: Computation of the Radius and Diameter of a spatial set. (computes also various other geometrical parameters)

The freewares are now shared in the Job Catalog of!

Freemat 3.5 now on!

Freemat 3.5 is now available on - Sun's Grid Compute Utility.

"FreeMat is a free environment for rapid engineering and scientific prototyping and data processing. It is similar to commercial systems such as MATLAB from Mathworks, and IDL from Research Systems, but is Open Source." - is Sun's Compute Utility tool where you can 'rent out' Sun's powerful hardware to run / test your applications.
Visit for more info.

How to run Freemat 3.5 on Sun Grid ?

1) Go to the Job Catalog section in and 'Checkout' the Freemat 3.5 Job. It should now appear in your 'jobs' section.
2) Create your 'Freemat Data Resource' - a zip file containing your input files and file called
3) The should contain the freemat commands to be run. Note that you need to specify only the arguments to the freemat command in the file. "FreeMat -nogui -noX -e" is taken by default.
4) Upload your file and point your Freemat Data Resource to the zip (by editing your Freemat 3.5 job)
5) Save and Run the Job!

A sample file would like


This will run two Freemat commands, viz
FreeMat -nogui -noX -e HermitianOperatorExample1
FreeMat -nogui -noX -e HermitianOperatorExample2

You can also compile Freemat on solaris and run it via SGE (Sun Grid Engine)

Web Developer Summit 2008

Am writing this post from the Web Devloper Summit, Delhi! Am too tired to take my cab after my long presentation and demo on Netbeans!

Sun is organizing the Web Developer Summit across 5 cities in India (Bangalore, Mumbai, Chennai, Hyderabad and today in Delhi). The summit is intented to spread awareness of Sun's technologies amongst ISVs.

The day kicked off with an introduction of Sun and its strategies followed by a presentation on Sun's hardware and software portfolio. Yousuf then spoke on Open Solaris followed by a Netbeans presentation and demo by me.

The ISVs present were attracted by the ZFS and DTrace features in Open Solari and by some cool netbeans editor features and the build in UML, Ruby, SOA and Web Services features of Netbeans!

Do watch out for the 2 day workshop that is going to happen in the same 5 cities where ISVs can get a hands on experience using Solaris, Netbeans and other cool Sun Technologies..

Here's Yousuf presenting on Open Solaris today at the Delhi Summit.

Quake III @ the IEC Open Source Mela

As part of the organizing committee for the IEC Open Source, I was asked to setup a gaming event during the 2 day IEC Open Source Fest!

With the Quake III source code GPL-ed, I compiled Quake III on Open Solaris and used the demo arena to setup a 'LAN Party!' The Open Solaris machines of course needed NVidia cards for better and smoother graphics and hence, I used 5 ultra 20 x86 machines with built in NVidia cards.

To run quake3, compile the GPL licences Quake III code (or you can use the packages available at, use the demo arenas available (place your pak\*.pk3 files in your baseq3 directory) and there you go!!!!

Me, setting up the gaming arcade..

IEC Open Source Mela!

The IEC Open Source Mela was a two day Sun event at Bangalore to create awareness of Open Source and Open Source technologies amongst Sun Employees. The two day event was held on the 25th and 26th of March. It was a packed two days with demos, talks and lightning talks all day, fun events and some gaming too!

Day 1:

After the inaugral and inspirational talk by KNR, IEC engineers were in for a series of talks surrounding open source! It was an excellent opportunity indeed to learn plenty of stuff about open source and more importantly to be aware of the work happening at Sun, India around Open Source!! The talks were around Sun's open source products like Netbeans, how to contribute to open source, etc. Simultaneously, there were demos happening to enlighten Sun fellow engineers on what Open Source Evangelists at IEC are upto!

The 'Gaming Arcade' was opened up post lunch and attracted plenty!!! Everyone tried their hands on 'Quake III' over the LAN! It was fun indeed to see people frag each other!!!

At the end of the day were some fun events followed by prize distribution for a few events that happened before the mela - the caption and logo contest and the acrostic puzzle! (I won the first prize! ;) )

Day 2:

The day kicked off with an excellent talk on the 'Do s and Dont s' in open source communities followed by some more amazing talks around virtualization, virtual desktops. The demos and the gaming arcade were there today too!! At the end of the day was a luck draw amongst those who attended many talks!

The IEC Open Source mela was a huge success indeed and of course sent the message across loud and straight - Open Source is the way of the future!!!!

Here's Swathi and me talking about the 2 day event!

A small quote that was put up during one of the talks - Open Source is a religion. Those who dont follow it go to hell! ;)
