As an aside, please, please just use the environment variables and other options the OS or language gives you to get at user directories, don't just construct them and don't make your own subdirectories in there. That's what APPDATA and so are for. Codel like this is why I still have programs using folders on my tiny C: when I've relocated everything to another drive, plus it might break on international versions of windows…

That's … I'm going to go have nightmares now >.>

I think if he's talking about having a bot check things in and out of a repository, VCS is a given?

#3 is what most wikis (at submission) and (distributed) version control systems (at a specifig merge/pull step) do, if you need inspiration.

If you're serving the content /on/ html pages to the authenticated users i think it would come down to checking referrer tags to make sure requests are coming from your site. There's probably more subtleties to it but from what i understand this is the foundation of all anti-hotlinking systems out there…probably?

It also feels related to the way the vast majority of things in computing with a source and a destination/target come in that order by default (screw microsoft symlink tool thing…); at least i see in/out as the same concept.

@ABoschman End of line comments universally refer to the line they're on. I've seen this comment type for simple descriptions of list items hundreds of times…

And since you have it in already, it's not worth the effort of removing, unless it's in a loop or something.

Of particular note, with things like sorting functions, it's much faster (in dev time) and easier to make a dumb simple algo do the right thing in all cases than to get an elegant algo fully functional and bugless. (Tho the only reasons to write a sort algo outside of acadamea are if you're building a library or working on a platform without one…)

Your wording indicates that you throw an exception from isValidDate; that's not what you want from a function with that name. isFunctions should return true/false unless it somehow can't be determined (isFileUtf8 -> true/false/CantOpenFileException?), and the answers below seem to have guessed that's what you intended.

If extended to quasi-planar points in 3d it'd make for a neat "edge ring from point cloud" function. Of course, in either number of dimensions there's plenty of datasets that would be pathological and create a mess, but hey, in actual use of some kinds you have a person eyeballing some data and deciding that some algorithm would be a good fit fbr the shape of it or a subset.

Agreeing with martain; for math-related recursion you need to do something with the return value from the recusive call. Heck, I'd say the two main recursion types are "aggregate a return value" and "do something to all nodes in a tree-like structure", the latter being where you don't care about the returns usually.

@Hurkyl What? How?

You can also monkey-stuff a missing onto an existing dict object of the base class and have it work as expected…
