For the past few years, my labor of love has been converting VHS, Betamax, and 8mm camcorder tapes to digital formats so they can be preserved. It's been a tremendous undertaking in my spare time that I hope to share details of in the future. But for now, I want to share one tip.

The Luhn Algorithm

The Luhn Algorithm

Checksums can be very helpful for validating that data is intact and free from simple mistakes. They are extremely fast to calculate, and computing power has made them all but trivial over the past few decades. Because of this, checksums often hide in plain sight. One of these is the Luhn Checksum, which is produced by the Luhn Algorithm. The Luhn Algorithm was invented by Hans Peter Luhn, a scientist at IBM. It's patent was granted in 1960, but has since expired and it is now in the public domain. The best place where you can find its handiwork? Your…
