Pacman: how do the eyes find their way back to the monster hole?
...st compared to any sort of pathfinding.
If you need it to generalise to arbitrary maps, you could use any pathfinding algorithm - breadth-first search is simple to implement, for example - and use that to calculate which directions to encode at each of the corners, before the game is run.

Can I incorporate both SignalR and a RESTful API?
... just use that code for reference.
This implementation is very similar (a bit more polished, includes tests etc.) to what Brad Wilson showed at NDC Oslo - http://vimeo.com/43603472

Calling C++ class methods via a function pointer
...myfunction (arg);.
This kind of thing is fairly common when using the old Win32 APIs, which were originally designed for C rather than C++. Of course in that case, the parameter is normally LPARAM or similar rather than a pointer, and some casting is needed.

HTTPbis adds a bit to this: "Various ad-hoc limitations on request-target length are found in practice. It is RECOMMENDED that all HTTP senders and recipients support request-target lengths of 8000 or more octets." tools.ietf.org/html/…

What is the purpose of XORing a register with itself? [duplicate]
...gister to zero, the compiler will often do it the fastest way it knows. A bit operation like XOR might take only one CPU cycle, whereas a copy (from one register to another) can take a small handful.
Often compiler writers will even have different behaviors given different target CPU architectures...
How to start two threads at “exactly” the same time

@Santa - The Win32 API for example offers different primitives. One useful type is the manual reset event returned when you call CreateEvent. msdn.microsoft.com/en-us/library/ms686364%28VS.85%29.aspx

My environment is Ubuntu 14.04 32-bit; I think I saw this before and after I activated my virtualenv.
UPDATE: even better, use python -m pip install <package>. The benefit of this is, since you are executing the specific version of python that you wan...
How to check what version of jQuery is loaded?
...
This is a bit better, but logging isn't that useful when working on an app. You're better off saving a variable first. let has$ = typeof jQuery === 'function'; console.log('jQuery' + (has$ ? ` version ${jQuery.fn.jquery} loaded.` : ' i...
Detect if a page has a vertical scrollbar?

Thanks. Quite a bit complicated! If you don't want to/need to be backward compatible is there perhaps an easier solution for html5 browsers? I mean perhaps the browser coders/w3c have been nice enough to just tell us if there are scrollbars ...
