In Git, how do I figure out what my current revision is?
...commit with a version number and then use
$ git describe --tags
to identify the current HEAD w.r.t. any tags. If you mean you want to know the hash of the current HEAD, you probably want:
$ git rev-parse HEAD

Internet Explorer 11 disable “display intranet sites in compatibility view” via meta tag not working
...: HTML1122: Internet Explorer is running in Enterprise Mode emulating IE8.
If so you may need to disable enterprise mode (or like this) or turn it off for that website from the Tools menu in IE.

If you want to derive from Foo then you should use the macro WITH_SELF_DERIVED in the following way:
class WITH_SELF_DERIVED(Bar,Foo)

You can even do multiple inheritance with as many base classes as you...
Running multiple async tasks and waiting for them all to complete
...r task2 = DoMoreWorkAsync();
await Task.WhenAll(task1, task2);
The main difference between Task.WaitAll and Task.WhenAll is that the former will block (similar to using Wait on a single task) while the latter will not and can be awaited, yielding control back to the caller until all tasks finish.

Maximum size of an Array in Javascript
..., the maximum length of an array according to the ECMA-262 5th Edition specification is bound by an unsigned 32-bit integer due to the ToUint32 abstract operation, so the longest possible array could have 232-1 = 4,294,967,295 = 4.29 billion elements.

If you need extremely robust fingerprinting, such that affine transformations (scaling, rotation, translation, flipping) are accounted for, you can use a Radon transformation on the image source to produce a normative mapping...

Is it possible for a unit test to assert that a method calls sys.exit()
...
+1, except that if he wants to verify that it calls sys.exit(1) (as opposed to, say, sys.exit(0)) you need to actually assert its code is 1. I guess you could do that with assertRaisesRegexp(SystemExit, '1')?
