Does anyone here find the list comprehension syntax awkward?
I like it because it is an expression rather than a series of statements,
but it is a little harder to maintain it seems.
e.g. you could do:
result =
for element in list:
if element == 'blah':

here's another interesting algorithmic exercise, again from part of a
larger program in the previous series.
Here's the original Perl documentation:
=pod
merge($pairings) takes a list of pairs, each pair indicates the
sameness
of the two indexes. Returns a partitioned list of same indexes.

Hello,
So, I need to have double linked, circular list (last element point to the
first one and first one points to the last one). I thought maybe I could
use list container from STL, but unfortunately probably not. I checked it,
and when I increase (++) iterator pointing to the last element the program

Is there a limit to how many items can be in a jump list?
My script worked fine with 126 items, but at 152 items it just doesn't
work. When I select a page from the drop down menu it will only bring
me to one particular Web page among the 152, a page I haven't
selected. It's the same page all the time.
The alternative reason why it...

Hi all,
I am new to the list and I didn't want to seem rude at all so I
wanted to ask if this was okay first.
I have a program I have written in perl which uses a postgresSQL
database as the backend. The program works but the performance is really
bad. I have been reading as much as I can on optimizing performance but
still it isn't very...

When my app starts up, it creates a temporary database. This temp database
is created from a 'model' database that is in the same folder as the
application. Because there is a model, the creation is essentially to just
copy the 'model' database and give it the name of the application with the
extension ".tmp".
Then code opens the temp...

I know the subject line is really bad. Here is the real question: we
have a web application that lists 1200 products. The web page present
only 12 products at once, if you wish to see the next 12 products, click
next page or the page index. This is a very common case.
e.g. (use fixed-width font for the following)

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
