Cigar and a Drink
I have been sitting on a photo that I took a while back but never got a chance to process and post. I was up late at night with a nice cigar I had bought on a bike ride earlier that day. Oh those Cuban cigars. I could spend an...

The purpose is to implement something similar to Remote Procedure Calls but without having to...
I recently changed my website from a bunch of hand-stiched webpages dynamically

/etc/wicd/encryption/templates/ and add the filename to the active file

Courses I Liked
An introductory course to crypto, drawbacks of old crypto methods, (very) basic
crypto analysis, designing (very) basic crypto. A must especially if Alfred
Menezes is teaching.
