These are great. It's unfortunate that if there's any minor bugs there's no way to really keep in sync though, for example the security issue mentioned in another comment in these comments. It would be cool if these examples could be wrapped up into some sort of convenient "package" or something like that, such that you could easily know if there are any updates and grab them, as well as just make it easier to grab these functions whenever you need them instead of copy-pasting them...
