    Powers of two are the roundest of numbers.

    They're not round, they're square!

      ITT: People who have never done low level networking.

      Edit: Without some absolutely crazy hacks, the smallest amount of data you can really transfer or compute on is one byte. 256 requires one byte, 257 requires you to DOUBLE the data used to 2 bytes. Multiply this by whatever data they send and the problem remains the same.

      This is the kind of thing that comes up a lot designing custom protocols.

      My experience is that a limit of 256 means they probably are willing to allocate up to 24 bits to send the value over the network:

      0x323536

      People seem to love to pass around their numbers as JSON or similar.

          Numbers guy here, I can confirm 256 is an evenly specific number, and not an oddly specific number.

                      That weird ass explanation with switches and "one of the most important numbers" still sounds absolutely clueless.

                          As a software engineer: actually there is no need for a number of people as a power of 2 unless you need exactly 1 byte to store such information which sounds ridiculous for the size of Whatsapp

                            Unless it's lua, then screw anyone programming with it.

                            Have to use lua for my current project and the 1-based indexing is really screwing with me.

                              I hate this. I love this.

                              If I ever make a game I might put stuff like this in it.

                              Having made a few games back in the day, this isn't something you add on purpose, this is something that you screwed up, are going to "fix later", then realize it's too much hassle to rewrite 45% of your code and you just raise the minimum spec requirements a bit to compensate.

                                It’d make sense at protocol level. Otherwise, yeah, even bit-size database columns end up being stored as a word unless the engine compacts it.
