Twisted has a "non-blocking" event loop.
I understand what a blocking event loop does (sort of, from the Wikipedia page) but can't figure out how a non-blocking one does.

I have always been skeptical of rewriting working code - porting code is no exception to this. However, with the advent of TDD and automated testing it is much more reasonable to rewrite and refactor code.
Does anyone know if there is a TDD tool that can be used for porting old code? Ideally you…

This is very basic question from programming point of view but as I am in learning phase, I thought I would better ask this question rather than having a misunderstanding or narrow knowledge about the topic.
So do excuse me if somehow I mess it up.
Question:
Let's say I have class A,B,C and D…

Is there an accepted general term that subsumes the concepts of variables, class instances and arrays? Basically "any typed thing that needs memory". In C++, such a thing is called an object, but I'm looking for a more language-agnostic term.

A lot of the code I've been working on recently, both professionally (read: at work) and in other spheres (read: at home, for friends/family/etc, or NOT FOR WORK), has been worked on, redesigned and re-implemented several times - where possible/required. This has been in an effort to make things smaller…

As far as I understand, when you write a for-loop similar to this one
for (int i = 0; i < SOME_NUM; i++) {
if (true)
do_something();
else
do_something_else();
}
The time complexity of this operation is mostly affected by the if (true) statement because the for-loop iterations don't…

I have a while loop to show the replies for a post on my website.
The value for parentID used in the query is $post['postID'] which is an array of details for the post being viewed.
As seen below it outputs the following (each subject is a link to view the full post)
$q = $dbc -> prepare("SELECT…

Hi, I'd like to find easier way to write loops inside loops.
Here is example code of 3 levels of 'for' loops:
int level = 0;
int value = 0;
bool next = false;
for (int i0 = 0; i0 < 6; i0++)
{
level = 0;
value = i0;
method();
if (next)
for (int i1 = 0; i1 < 6; i1++)

I have a program to use the IMDB database and am having very slow performance on my query. It appears that it doesn't use my where condition until after it materializes everything. I looked around for hints to use but nothing seems to work. Here is my query:
SELECT *
FROM name as n1
FULL JOIN…
