Thursday February 19, 2009 Another Sunny Day has Come and Gone Away...
..Let me go home. It has been 2 days now in the Sun Tech Days 2009 - Hyderabad and I'm already feeling worn out. It was my privilege to interact with some 1000+ odd (really odd) crowd. I had my own share of fun, laughter, serious pep talks, being-pushed-out-of-my-pod moments, which in a way is the characteristic of Tech Days and I love every bit of it.

Pic- A strange pod setup that allows the crowd to breath down your neck while you are demo'ing!
I was fortunate enough to meet some brilliant developers from Oracle, Progress, TCS, Infosys and more. Jacob Royal, my pal has an extensive blog entry on the things that we did. Read on.

Wednesday February 11, 2009 Text Juggling with BWT
The most fascinating use case of the BW Transformation is the ability to scramble and recover text data by doing complex block sorting techniques. There are many text compressors already using BWT but there aren't many BWT based text scramblers.I built a simple no-brainer tool based on Swing that can be used for scrambling (muddling) text data. You muddle a block of text using forward BWT to obtain a non-readable text block and a muddling key. You can use this key to do the reverse BWT and get the original block of text.
The above screen shot shows the tool in action. To run this JNLP based application, you need to have the Java browser plug-in.
Launch the Muddler Application
