as fast as Java or C++, threading
sucks, memory usage is higher, etc.
One of the design constraints we face

How to make a flat list out of list of lists?
...sublist in l:
for item in sublist:
flat_list.append(item)
is faster than the shortcuts posted so far. (l is the list to flatten.)

Is floating point math broken?
...able depend on the division method: slow division such as SRT division, or fast division such as Goldschmidt division; each entry is modified according to the division algorithm in an attempt to yield the lowest possible error. In any case, though, all reciprocals are approximations of the actual re...
What's the correct way to communicate between controllers in AngularJS?
.... $broadcast now avoids bubbling over unregistered scopes and runs just as fast as $emit.
So, now you can:
