New Addition to Tabulator

For those of you don't know Tabulator is a RDF data browser originally hacked up by TimBL, and developed over the years by summer interns at DIG.

For the past few weeks, I've been trying to understand and write code for the Tabulator. My task was to provide a justification trace for the annotated transaction log given out by the AIR reasoner. Here's a screen shot of how it looks like now:
If you want to try this out, install the Firefox Extenstion with this latest change, restart Firefox, and navigate to this file.

Overall, my experience with the Tabulator code amazes me as to what javascript is capable of. But however, I've had my share of nightmares debugging the code! Sometimes it was pretty painful, but nevertheless I learnt so many lessons :)

By the way, the Tabulator project is open source, so if you'd like to contribute you are more than welcome to do so.

I've always wanted to do number manipulations in my head. I am no savant, so the best I was able to get to was powering up any 2-digit numbers within my head in less than 20 seconds. It's a very simple trick where you multiply the nearest whole number with the equi-distant number from the number you are actually squaring and adding the power of the distance. For example, if you want 99^2, you do (99+1)*(99-1) + 1^2.

I came across this on Google Video and I find this man to be simply amazing...

Home Page

I finally created my home page!

I've been putting this off for weeks, and I am glad that it is over. I built the site with Apache Forrest.

Girls' Day Out

So, it was one of these long holidays with Veteran's Day falling on Monday. Since I would get awfully bored with 3 days on a row at my apartment alone, I called up Varuni and we planned a day out exploring Cambridge (mostly around MIT).

We first went to the MIT Museum which is very close to where I live (shame on me for not visiting it before!). I was very eager to see the hologram gallery. I was really fascinated to see what laser and few pieces of glass could do! For example, you can see the following "portrait" in 3D!

For some odd reason Varuni was very much intrigued with this "oil bathing machine". I found it quite gross actually :) Anyway, it was very nice to see very cool mechanical things which were just built for fun.

My favorite section was of course the robots! Sometime back I watched a program on Discovery about Kismet - a sociable robot developed at the MIT AI lab. And yesterday, I was looking face to face with this Kismet!

We then explored some parts of MIT. I was of course playing the role of the tour guide - showing what little parts of MIT I knew to Varuni. Here's both of us standing on the lawn in front of the Oval auditorium right next to the Student Center.

Then it was the Charles River... the view was so breath taking. May be it was the lighting condition and the time of the day or even the weather. I don't know what, but somehow, it was so nice.

This is a picture of both of us in front of the river.

Of course you can see the Boston skyline behind. Here's the other part of the skyline .

We also went down to the MIT boat dock yard, and said hello to these cute friends!

All in all, it was a very nice day indeed!

Daylight saving time

This is not any major news.

But the interesting thing is now I am 16 hours behind my brother who lives in Melbourne, Australia!

It used to be 14 hours, but on last Sunday my time here was pushed back by one hour to mark the END of daylight saving, and his time was pushed forward by one hour to mark the START of daylight saving time!

We had to coordinate different calling times, cos either one of us would be either at work/uni or too sleepy to talk :)
