Ever since I saw the “Annotated Time Graph” on Google Finance, I wanted to use it in one of my projects. Finally, I got a decent scenario to use the visualization.
BoiledBeans scanner plots all questions ever posted on bb based on their difficulty levels. Check it out here
The backend magic is delivered by SQL and php and front end is of course powered by Google Visualization API.
Please tell me how it is!
A few months ago, I conducted a Kannada quiz for the Sacramento Kannada Sangha. Since people were fond of buzzer rounds, they requested me to have one. I hate buzzer rounds because it is very hard to arbitrate who hit the buzzer first. To solve this problem, I rigged up a micro-controller based Quiz Buzzer which talks directly to a computer via RS232 and clearly displays which team hit the buzzer first! Since we had a huge screen and a projector set up at the location, the entire audience could see the team number as soon as someone hit the buzzer.
I got some overwhelmingly good response for the buzzer and I decided to make it available for download.
KapaLa Moksha — Quiz Buzzer v0.1
Features
Hardware requirements
*n = number of teams < 8
Thats it!
Downloads and implementation instructions
The thing is really nifty and can make audience very happy!
The Name: KapaLa Moksha in kannada stands for “One tight slap”.
We recently posted our 500th question on Boiledbeans and to celebrate, we conducted a Live Quiz Contest.
I built a neat bash like interface for the quiz using Mootools ( and of course, Javascript and HTML ) and people really liked it!
Take a look at it here!

I am planning to make the code public in a while. Since the quiz is still alive, I cannot release it immideately.
Wish you a very happy and prosperous new year!
I was at my friend’s place yesterday for new year celebrations and we needed a random number generator to play bingo. Instead of writing numbers on chits and picking them up, I hacked together a random number generator using Javascript in about 15 minutes, which looked like this:
I used a simple hash to see that numbers did not repeat and It actually worked pretty well. I was delighted at Javascript’s utility at non geek parties!
Here is the code:
<!-- Devadutta Ghat, last piece of code written in 2008 ;) --> <html> <head> <title>Bingo Baby!</title> <script type="text/javascript"> var gblHash=new Array(); function getNewRand() { return (Math.floor(Math.random()*99)+1); } function getRand() { var ilm=getNewRand(); var i=0; while(gblHash[ilm]==1) { i++; ilm=getNewRand(); if(i>=100) { alert("All numbers done!"); return; } } gblHash[ilm]=1; document.getElementById('randomNumber').innerHTML=ilm; document.getElementById('drawnNumbers').innerHTML +=(" "+ilm); } </script> </head> <body> <div id="randomNumber" style="font-size: 150pt;">-1</div> <input type="button" onClick="getRand();" value="Clicky!"> <div id="drawnNumbers"></div> </body> </html>
And here is a demo
Enjoy 2009!
This is an English quiz, written in PHP. You can play this to improve your vocabulary and prepare for tests like the GRE or just to have some fun.
NEW!! Updated to the Barron’s GRE word list!! Has 4816 words in database!
Click on the image to start playing
I had originally coded this in 2005 when I was preparing for the GRE. Although the wordlist I have had (now with Barron’s word list) is not very good, the game is not bad. It did help me in the beginning.
This release is officially version 1.1

This Greasemonkey script encrypts the contents of a text box on a web page using the rot13 cipher at the click of a button.
If there is a clean text box on a page, the e13 button pops up next to it. Click on it and the text inside the box will be rotated by 13.
well, here are some examples of the operation

nodeGravity is a novel way to visualize web-site statistics which I had devised sometime ago.
Each article on this page falls into a category like downloads, news, projects etc. nodeGravity uses the number of visits to that particular category and the number of nodes in that category to render and visualize web stats according to Planck’s black body radiation and Newton’s Law of Universal gravitation.
Here is an example
Simple interpretation of the stats are this
The color is calculated using Plank’s black body radiation laws, which says that the hotter a star is, the lesser the wavelength of the emitted light will be.
Newton’s Law of universal gravitation comes in to associate energy to each node, based on its mass and number of visits.
Hope you enjoy it!

jam mASHtra: Just a minute mastering ashtra ( Asthra in sanskrit means tool)
Last year, for Udbhav at MSRIT, I conducted a Kannada Jam competition. The day before the competition, I was worried that no one will turn up for the competition. I thought it would be a flop. But to my surprise, the event saw a full house audience. I was forced to finish the competition by the admin staff since I had exceeded my time slot, but the audience did not listen and forced me to conduct it for some more time!
It was a thrilling experience.
One of the reasons behind the success of the event was, jam mASHtra.
jam mASHtra: Is an automatic and easy to use jam timer. I coded this the day before the event just to save myself from keeping insane jam logs for each participant.

In a lightning speed hack, I changed the interface to the gallery and it looks surprisingly good. A sneak preview is shown here
You can visit the galley section to check it out.
quot;The dayquot; is here! This update is a part of the celebrations.
