PyCon Au 2013 started yesterday with miniconferences for Django and OpenStack and snow on Mt Wellington.
The DjangoCon AU miniconference had a capacity audience and an excellent set of presentations, with keynotes from Alex Gaynor and Dylan Jay.
The opening night was devoted to Code Wars (not Cod Wars), with a fiendish set of puzzles to whittle the competing teams down to the eventual winners: team IC. The theme of the night revolved around PRISM, the NSA, conspiracy theories and Geocities-styled web pages. The puzzles were:
- Find a backdoor on a website to access a login page and then convert CSS tags into binary and then ASCII to get the password
- Convert a base64 encoded string into a PNG image, recreate the original image through rotating image tiles (to get an image of a prism) and do some bit manipulation of the image to get another password
- Convert an embedded Midi file into a CSV, decode data in the CSV file to get yet another password (this was the round where desperate people resorted to Ruby and Perl…)
- The creative round for the final showdown: Create a UFO tracker for the Canadian government, with an NSA backdoor
