Breaking a simple text based CAPTCHA

It took me about a week of my Dashain vacation to make this simple captcha breaker (5 days to be exact). I had been reading Image Processing in my CS undergrad for some time then, and wanted to put my skills to use, although, I must admit, its not as overly complicated or full of image processing bits as I'd have likely enjoyed.

Handwritten Devanagari Digit Recognition using Neural Network

Neural Network was one of the electives available during my 5th semester, and knowing that it was available, I was certain that I wanted to study it over any other electives.

I, obviously, wanted to study Neural Net and could not convince the college on teaching ANN instead of Cryptography. I was left with no choice but to study both, which I did. A few of us studied both the subjects as an elective. Since the teacher was not available during the weekdays, we took classes on every weekend for 3 hours each.

How to login to a website via Google Script?

Whenever I have to accomplish something these days (in terms of programming that is), the language that I turn to at first is Google Script. I have gotten so used to it, and its interface that I prefer it over any other language, or services. The added bonus of using it is that you can run the script regularly by setting up a timer. No need to meddle with cronjobs and what-not on your server.
