Finally a contest with more substantial prizes. I can't help feeling that lately virtually all companies have been launching contents to solve (very) difficult problems, but instead offer only rewards that coincidentally, just the persons with the most experience/most qualified, would consider undignified. (like the recent NASA ISS contest or most of the competitions on Kaggle).
they call the url param as supidlink :)
Actually I added that parameter. That page should use a permalink, but unfortunately it doesn't. I tried to submit the post but that url was used by the same event a year ago.
