Python contains useful modules to execute file and folder operations. It makes use of the ‘os’ module to carry out file system operations. To illustrate, the python code to get the current working directory is: import os os.getcwd()import os os.getcwd() . On OSX, the output of that is: ‘/Users/vikrambahl/Documents”/Users/vikrambahl/Documents’ . The ‘os’ module makes it easy […]
OpenGL mesh viewer
This application was the first one I created while learning computer graphics at NTU. It parses a .m file, which is nothing but a bunch of numbers representing vertices (x, y, z) in the 3D plane. The resulting 3D model is displayed in the viewport. Options for orthogonal/perspective projection along with various viewing options to […]
Secure Data Sanitization
Published a paper on techniques for shredding data from storage devices. Guttman’s algorithm to DoD to the NSA algorithm were all put to test on a 1GB flash drive. The results were published in this paper.
Signal processing with python
Gave a talk on audio signal processing with python at PyCon Singapore 2013. I started using python to quickly prototype a beat recognition system for my masters dissertation. I realised the power of python in signal processing. The speed at which you can test algorithms is astounding. You can perform a cross FFT on the […]
Develop a simple chrome extension
I almost exclusive use google chrome (unless I need firebug on firefox) for web browsing. It is highly cutomizable, powerful, fast and you can get super cool extensions and apps from the google play store. I use a lot of chrome extensions like xmarks, evernote, google dictionary, mozbar etc., so I had an idea for […]
