Kerala is called “God’s own Country”. I dismissed that as a mere exaggeration until I got a chance to visit it once a couple of years ago. I was invited to “Renaissance”, an inter-collegeate fest. The visit was also coupled with an official trip for a product demo to an important customer in Tiruvananthapuram. The train journey is one that will remain in memory forever. Kerala has some of the most stunning track side sceneries in the country. I can safely say this since I have also travelled northward up till Himachal by train. Last year as well, there was an invitation for a talk, but I was unable to attend since something else official had come up.
But this year I was informed of the event about 2 months in advance, which allowed me to plan well. I chose to speak on a couple of topics:
1. The history of the PC
2. Linux development tools
My talk was scheduled on the 16th and I took a train from Chennai on the night of 15th. Thrisur is about 10 hours by train. There is no airport in Thrisur and a flight plan was ruled out. The train must have reached by around 7 a.m or so and as I walked towards the exit, there were 3 students from GEC, one holding a plackard. I was then taken to “Ramanilayam”, which Pramode later told me is a guest house for ministers. It is a very simple place with many large rooms.

This is the same place that I stayed the last time I was here. After having a shower and breakfast, I was picked up and taken to the college auditorium where the inaugural function was to take place.
The hospitable students took very good care of me and in a while Pramode walked in. After the event was declared open in the inauguration, first up was Anivar Aravind’s talk on “Free Software Philosophy”. The slides he prepared were just wonderful and concentrated more on general culture rather than on the terse philosophy. I think the point that he was trying to drive home was that humans are just too used to copying, in all forms of art and that should be the case with software as well. I agree with him.

Later, Pramode, Anivar and I visited the FOSS exhibition, where interesting projects were on display. Here are some of them.

Insignia 06 was attended by many school students, which I think is very good for them. On the right you can see an old Wipro computer, to me it looks like a mini.

On the the left you see a student demonstrating PWM using RTAI, or atleast it was the intention. She told Pramode that there was some problem getting an RTAI patched kernel to run on that machine. Still, the concept was conveyed. Pramode has writen an article on the subject. You can read it up here. On to the right you can see wires hooked on to a PC’s paralle port. Many interesting projects were done by using the PC’s parallel port and controlling it from Linux.

The guy on the left demonstrates a Puppy Linux Live CD and on to the right is an openMosix 2 PC cluster. You can find an article I wrote for “Linux for You” on the subjects in the “Articles” section.

Some antiques were on display. Look at the platters of a hard disk and the thr right is the famous M68K CPU.

On to the left is a web cam controlled with a stepper motor. Added to that is Motion, a motion detection software used mostly for security applications. To the right is a Lynx/Lyx stall.

As a kid, I was always enthralled by battery powered toys, especially trains, since you did not have to run behind them. Here is one controlled by the parallel port. The “station” can detect it using a reed relay. You can see the magnet on the train in the picture on the right.

To the left is an electromagnetic Tux and on the right are posters made on Computer Science greats, Pramode and Anivar Aravind look on.
Post lunch talks are challenging. No matter how talented a speaker you may be, keeping the audience awake can be a struggle. The better you are, lesser people sleep. My second talk was dropped since there were not enough “technical” audience.

In the afternoon, I had the chance of attending the “Hack a mobile with Python” workshop by a couple of dudes. It described the capabilities of Nokia’s Python port to the Series 60 Symbian phones. I must say that more than the capabilities of the phone itself, the demo items were very interesting. Almost all the demos were done in association with a Linux PC that had a bluetooth dongle. Then by running programs that both on the PC and the phone, some amusing results were attained.

Start_here:
The “Hack a mobile” workshop guys and the Car demo. The car remote control was hooked up to a PC parallel port. A Nokia mobile was then used to control the car. The Linux PC was equipped with a Bluetooth dongle. A Python program on the mobile communicated with the PC through Bluetooth controlling the car. Confused? goto start_here;
OK, don’t use “goto” other than in kernel code and blogs.

In the evening, Pramode took me to an Altermedia showroom. These guys are pretty interesting. I bought a copy of Stallman’s essays for Rs. 110. I was printed locally, with an introduction by a local guy. Free media surely rocks. It was very nice to see a copyleft notice, that read “Verbatim copying of this work in whole or part is permitted, provided this notice is kept intact”, rather than some notice that warns you are legal action if you even tried to photo copy it!
After dinner, I took a train back to Chennai.
