Every time I've tried comparing cuckoo hashing vs traditional hash algorithms in practice, the time taken to compute the additional hash functions outweighs any gains in performance. Counter-intuitively, I've also noticed in many cases that

One interesting tidbit: the most popular support request we've received since launching is to make the service available in the US and Canada. One natural reason that this situation has gotten worse is that the credit card market has become

Try an iphone app like "Sleep Cycle". It's worked just as well for me as the $150 "SleepTracker Pro" I bought a few years ago. Arguably better since the iphone app provides nice graphs and soothing wakeup music. Does it work? I do feel like
