I have been spending my free time getting together the Machine Learning community in Hyderabad and kick start a series of session on the topic. The turn out was great for the first session.



Gestalt Principles

In 1910, psychologist Max Wertheimer had an insight when he observed a series of lights flashing on and off at a railroad crossing. It was similar to how the lights encircling a movie theater marquee flash on and off. To the observer, it appears as if a single light moves around the marquee, traveling from bulb to bulb, when in reality it’s a series of bulbs turning on and off and the lights don’t move it all. This observation led to a set of descriptive principles about how we visually perceive objects.

Prioritizing elements in web pages using Science

This series of posts will be a bit different from most of the random experiences posted in the web log. Most of the following is insipred from pioneers in the field of Design Thinking and Front End Design. Based on the foundations laid out, I will propose a methodology using which a web page can be better structured and orgranzized to improve a users experience. The goal of this series is to understand a web page from an individual perspective and manipulating the design based on his personality pro-actively.

Bring the past to the internet - Digitization of Print

charan puvvala

I was working with a university a year back where I assisted them in digitization of a select collection. This involved careful planning lots of dirty work, one software dev, proof checking and 5 man team working for 45 days to complete it. The end result was immensly satisfying. The 320 books that were digitized were available to the public at the Digital Library of the University. Previously one would have to take prior permissions from a hierachy of people to be able to access these books due to the fragile nature they in and the value they hold.

Build a Device Lab with $4

A device lab is a responsive device holder which eases the process of responsive development or cross-device testing while building apps which are meant to be device agnostic.

Below are a few sample Device Labs.
