The eternal computer science debate that makes absolutely no sense to normal humans: endianness. On the left, the logical person crying because "end" should refer to what comes last (little-endian should be MSB first). On the right, Danny Cohen smugly enjoying the chaos he created by naming it backwards - where "big end" refers to the most significant byte coming first.
For the uninitiated: endianness determines how multi-byte values are stored in memory. It's like arguing whether to read a number from left-to-right or right-to-left, except we've been fighting about it since the 1980s and nobody will ever surrender.
