How do I get an HttpContext object from HttpContextBase in ASP.NET MVC 1?
...mple illustrates how you can do this. It supposes you have a method called Foo that accepts context as HttpContextBase but then needs to call a method in a third-party assembly (that you may not have the good fortune to modify) that is expecting the context to be typed as HttpContext.

Why use the params keyword?
... allows you to call the method with a single argument.
private static int Foo(params int[] args) {
int retVal = 0;
Array.ForEach(args, (i) => retVal += i);

What is getattr() exactly and how do I use it?
...ethod name.
For example, you cannot do this:
obj = MyObject()
for x in ['foo', 'bar']:
obj.x()
because x is not of the type builtin, but str. However, you CAN do this:
obj = MyObject()
for x in ['foo', 'bar']:
getattr(obj, x)()
It allows you to dynamically connect with objects based o...

Using bitwise OR 0 to floor a number
...and only an integer (as in the Elm source code @dwayne-crooks linked). And foo = foo | 0 could be used to coerce any value to an integer (where 32-bit numbers are truncated and all non-numbers become 0).

cd bar
# edit
git commit -a -m "foo"
git push

Create list of single item repeated N times
... change one of them, they all change because they're all the same object:
foo = [[]] * 4
foo[0].append('x')
foo now returns:
[['x'], ['x'], ['x'], ['x']]
But with immutable objects, you can make it work because you change the reference, not the object:
>>> l = [0] * 4
>>> l[...
