Nice video that talks about Hamming Codes and gives a hypercube explanation that helps understand Hamming Distance

On sabbatical
I noticed that my e-mail has some CRC queries. I'm on sabbatical through summer 2017, so there might be significant delays before I'm able to respond to e-mails. If you notice something that seems to be a problem please do let me know, but please bear with me until I have time to respond.
(Contrary to what some might think "sabbatical" is usually the opposite of "vacation" for engineering faculty. It is a chance for us to concentrate on a large difficult problem that we can't do during normal semesters because of all the many demands made upon our time.)

Why To Avoid Hash Algorithms If What You Really Need Is A Checksum
Sometimes we hear that someone plans to use a hash function for fault detection instead of a checksum. This is probably not the best idea, b...
