    Just rewrite this small library to generate forms automatically on Android (my latest side project) :)

    In future, probably, I will add more form elements and maybe more form data store to save to sqlite/memory instead of SharedPreferences.

    Below is the github project:

    Android Quickform

    Some quick notes:

  • Fun scraping with casperjs and phantomjs

    Recently, I have been playing around with CasperJS and PhantomJS for web scraping. I always find screen scraping fun and fascinating. I mean there are just so many applications:

    1. We have bills/accounts all over the place in different websites. The scraping tools can be used to develop a program for personal use that can combine the results in a single place.

    2. We want to find and compare the...
