Hey! I'm David, the author of the Real-World Cryptography book. I'm a crypto engineer at O(1) Labs on the Mina cryptocurrency, previously I was the security lead for Diem (formerly Libra) at Novi (Facebook), and a security consultant for the Cryptography Services of NCC Group. This is my blog about cryptography and security and other related topics that I find interesting.

I've open sourced my tournament app posted December 2014

Since I've made my first tournament app in ~2005-2006 I received many request to make an open source version available. Back then I didn't really want to release something badly coded so I just kept it for myself and allowed people to go through my online app to create tournaments.


It caught up, it was translated in 8 different languages (sometimes badly translated though) and used all across Europe in real life and on IRC (I think there was something like 7000 different organizations that got created through the app). One day some dude skyped me and offered me 80€ for the sourcecode. I made 80€.


I then rewrote everything using new technologies I had learn or I wanted to learn. CodeIgniter, Zurb Foundation, jQuery, Sass... It was kind of a mess and I must have scared away all the users it had. Eventually I didn't renew the domain name and people started complaining and asking me to hand them the app.


I was sad that there was so many people asking for a tournament app, and that mine was not out there anymore. So yesterday when someone asked me if he could have the code I uploaded everything on Github. The code is old, and it's a mess. The sass is nowhere to be found. I even wonder if it's really secure. But it works, it's easy to setup, and if it gains traction I might want to get back into it. If there was one project I fell in love with, it was this one.


Well done! You've reached the end of my post. Now you can leave a comment or read something else.
