It also turns out that two's complement makes arithmetic a LOT easier in most cases, though you'll have to go to Wikipedia for that. So we actually have 2 32 possible states for the integer, once you include zero. If there's a combination, you add their values here's a 4-bit example: If all the bits EXCEPT the first are on, that's the largest positive number we can represent: 2 147 483 647. So if the first bit is on, and all the others are off, that's the lowest number we can represent: -2 147 483 648. Instead, we set the "highest" bit to be negative, and all the others positive. If we were, as you assume, using the first bit as "negative / not negative", we couldn't possibly store - 2 147 483 648, since we couldn't count that high!īut that's not how we count. In cognitive tests, based on video recordings of game. The largest number you can represent, counting upwards, with N bits is 2 ^ (N) - 1. distances covered in physical tests, while the effects of mental fatigue on. Luckily, it was just a build system issue so it didn't break anything important.
Sometime in there, my VPN connection died, but it does that without provocation anyway and all that clock stepping probably made its tiny head asplode.ĮDIT: Funny story, now that I think about it: a customer of the company I work for had their clock accidentally set past Y10K, and our software (rather embarrassingly) broke as a result - there was an assumption that a timestamp would, when formatted, be a certain number of characters and it failed in a very roundabout way as a result. Surprisingly, the things I could find with a year on them without thinking too hard work fine: date, the gnome clock widget and its calendar. 10000 - azureus Wvuze (a java app) shat itself and started using 100% CPU.There's little value in representing dates before the protocol was invented when the purpose of the protocol is to determine the current date. I can't be arsed to calculate the exact boundary, but it's not what you'd expect because NTP has its own time scale. The protocol is probably incapable of representing dates this far in the future. 2099 - ntpd sets the clock forward instead of backward.2038 - No problems whatsoever, except that thunderbird immediately notified me that my TLS certificate had expired.My experiences with setting the clock to the far future on a 64-bit linux system, inspired by this post: Are you interested in promoting your own content?
