I am using this code:
$page = int(param('page'));
This sometimes results in:
warning: Use of uninitialized value in int
Is this a good solution to resolve this warning, or is better and more succinct code available?
if (defined param('page')) {
$param_page = int(param('page'));
} else ...

I have implemented a basic (naive?) LINQ provider that works ok for my purposes, but there's a number of quirks I'd like to address, but I'm not sure how. For example:
// performing projection with Linq-to-Objects, since Linq-to-Sage won't handle this:
var vendorCodes = context.Vendors.ToList()....
So we have:

I am working on a biometric matching system and I would like to have few suggestions regarding vectorizing the following code:
ref_points=size(tpol,1); %number of rows=number of reference image points
in_points=size(ipol,1); %number of rows=number of input image points
radsize=7*ones(re...
I ran into a problem in my app where under some conditions, a view controller might be loaded more than once before its deinit (where I was previously removing the observer) is ever called. So the notification was being added twice occasionally and causing some problems.
To fix this issue, I ju...
I've made a couple of suggested edits to this question. The first one was rejected because it deviated from he original intent / it edited code. When I looked at the suggested edit, it did look like I had just hacked away at the code, so I wasn't surprised it had been rejected.
I made a second...

Handling HTTP errors
This code seems to be intended to handle 404 Not Found response when downloading a url:
# Grab the page, raising an exception if it doesn't work

if '40' in str(response):
raise Exception('Couldn''t find page!')

I struggled for the last couple days on this question and finally came up with a solution. But it's got so many loops I get dizzy just looking at the code - from recursive functions with loops to loops within loops.
I really expected to find a canned function in a popular XML class to extract al...
I had a complex query in the controller like:

As mentioned in the answers to a very similar question, scribbling over part of an image will destroy the original pixels, assuming that your editor doesn't store any layers or undo history. (Paint doesn't.) There are some things to watch out for, though:
