Regula: An annotation-based form-validator written in Javascript

Posted on March 30, 2010March 30, 2010 by vivin

Regula is an annotation-based form-validation framework written in Javascript. There already exist a few frameworks that address form-validation in Javascript, but I have found them to be somewhat lacking. I have thought about writing one of my own for some time, but I honestly had no idea what form it would or should take. I…

A brainfuck interpreter in bAdkOde

Posted on January 23, 2010January 28, 2010 by vivin

A few days before I left India, I started writing a brainfuck interpreter in bAdkOde. I finished implemented all the instructions, excepting for looping. I actually finished the code (and fixed all bugs) while I was in the air, flying from Dubai to Los Angeles. Emirates Airlines has power-plugs for your laptop on the seat….

bAdkOde is Turing Complete

Posted on December 26, 2009December 26, 2009 by vivin

In my previous post, I suggested that bAdkOde might be Turing Complete by writing a quine. One of the ways to actually prove Turing Completeness is to try and write an interpreter for another Turing-Complete language in bAdkOde. Another approach involves providing a direct translation from another Turing-Complete language into bAdkOde. Here, I prove the…

A bAdkOde quine (which suggests that bAdkOde is Turing Complete)

Posted on December 25, 2009January 23, 2010 by vivin

On the bAdkOde project page, I mentioned that I didn’t know whether bAdkOde is Turing Complete (although I suspected it). I also mentioned that if I was able to write a quine in bAdkOde, then it would probably mean that it is Turing Complete. I was able to write one after going through this excellent…

if-else in bAdkOde

Posted on December 16, 2009 by vivin

I was talking to my CSE 200 (my first CS class at ASU) professor Richard Whitehouse about bAdkOde and he (rightly) pointed out that it didn’t have an explicit selection statement. He also said that unless I wanted it to be really ugly I’d need to have a selection statement. However, since I was going…

bAdkOde: An Esoteric Language

Posted on December 13, 2009December 14, 2009 by vivin

I’ve added another project to the projects page. It’s called bAdkOde, an interpreter for an esoteric language that I designed. The very first incarnation of bAdkOde was written in Java and I actually posted it (or made a blog entry about it) over 8 years ago. For some reason I took it down. Probably because…

Sulekha: A text-based Markov-chain generator

Posted on July 5, 2007September 9, 2009 by vivin

I’ve finished work on the projects page. Sometimes I’ll have a passing interest in something that leads me to write some code for fun. Yes, you read right. I like to code… for fun. Anyway, this is something I’ve done ever since I started programming way back in 1991. I’ve written a bunch of cool…

Artificial Life – some preliminary findings

Posted on October 19, 2004September 9, 2009 by vivin

I fnished my artificial life simulator over the weekend, and I have been running simulations on it. There were a few bugs initially that I quickly fixed. My initial simulations gave me some inexplicable “population explosion”. For example, in one cycle I would have 31 creatures and in the next cycle I would suddenly have…

Intel and Artificial Life

Posted on September 17, 2004September 9, 2009 by vivin

This is my fourth day at Intel. I think I will enjoy working here. I haven’t done much yet though, and I still don’t know exactly what it is I am supposed to be doing. I tested some 140 chips yesterday, but that wasn’t too much work. My supervisor is out until Tuesday, so until…

Ecological Simulators and Photo Albums

Posted on September 27, 2002September 4, 2009 by vivin

I finished the “Delete Photos” page on the Photo Album Tools page… which of course, none of you can see, since it’s in the admin section. But anyway… It took me this long, because I had other stuff to take care of… namely CSE 421. I only have the “Update Photos” tool to finish… after…
