Early research on Indian scripts rendering and input in Linux/X

Posted by hooeezit on February 1st, 2010

Hindi_KWhen I was in junior year of college in 1998-99, I worked on a project at the Indian Institute of Information Technology in Hyderabad, India under Dr Rajeev Sangal and Dr Vineet Chaitanya. My programming partner, Naoshad Mehta, and I collaborated on adding support for Devanagari script in X under Linux through ‘rxvt’. We called the modified version ‘rxvt-idev’. The results were so well received, that Naoshad and I received a Department of Electronics, Govt. of India grant to continue the work and add Indian script I/O capability to X in general.

Farmville’s interactivity is far more visual and engaging, so I actually spend time playing Farmville. Here are some thoughts on maximizing your returns from the game. Read the rest of this entry »

Extracting WAV file header information using a Python script

Posted by hooeezit on August 18th, 2009

I am currently working on WAV file playback in an embedded device. To store WAV (PCM) sounds on an embedded device, you need to strip the headers and extract the uncompressed PCM data from the file. My previous post shows how to convert the binary data from the WAV file into a C array that can be included in a project as a source file. In this post, I show you how to figure out where the PCM data lies within the WAV file.

Embedding a binary file as an array in Firmware

In this article, I show you a Python script that can convert any binary file into a C array encoded in hex.

Table Join Operation in Excel

Posted by hooeezit on August 16th, 2009

The interactivity of Excel makes it a very handy tool for data analysis. But Excel excels only at numeric analysis. Unfortunately, tabular/set analysis is not inherently supported in Excel and you have to jump through hoops to do that. I’m posting the source code for a VBA subroutine (Excel Macro) that performs one of the most common tabular operations – a Table Join. The subroutine here takes 2 tables in the form of ranges, and the name of the join field as input and produces a new worksheet with the joined table as output.
