unusual facts about modulo operation


Link aggregation

;XOR (balance-xor): Transmit network packets based on (source MAC address XOR'd with destination MAC address) modulo NIC slave count.


Hex dump

When hex dumps are intended to be manually entered into a computer, such as was the case with print magazine articles of home computer era a checksum byte (or two) would be added at the end of each row, commonly calculated as simple 256 modulo of sum of all values in the row or a more sophisticated CRC.

Holographic algorithm

Soon after, Valiant found holographic algorithms with reductions to matchgates for #Pl-Rtw-Mon-3CNF and #7Pl-3/2Bip-VC.
