Why does calling a function in the Node.js REPL with )( work?
...changed for 0.11.x, which will just wrap { ... } rather than all input:
if (/^\s*\{/.test(evalCmd) && /\}\s*$/.test(evalCmd)) {
// It's confusing for `{ a : 1 }` to be interpreted as a block
// statement rather than an object literal. So, we first try

How does this giant regex work?

@Peter: try print_r($replacement_string);. I feel dirty now. Basically, it translates to eval(gzinflate(base64_decode(etc))); That etc is a whole mess of php code encoded in base 64. Functions are error-escaped. eval($_POST) everywhere.

What you're asking for is extremely hard. If possible, getting the user to specify the encoding is the best. Preventing an attack shouldn't be much easier or harder that way.

What APIs are used to draw over other apps (like Facebook's Chat Heads)?

Finding the index of elements based on a condition using python list comprehension
...xes for this at all, but just deal with the values—[value for value in a if value > 2]. Usually dealing with indexes means you're not doing something the best way.
If you do need an API similar to Matlab's, you would use numpy, a package for multidimensional arrays and numerical math in Python ...

How exactly does a generator comprehension work?
...
Do you understand list comprehensions? If so, a generator expression is like a list comprehension, but instead of finding all the items you're interested and packing them into list, it waits, and yields each item out of the expression, one by one.
