Python Infinity - Any caveats?
...verflowError: (34, 'Numerical result out of range')
The inf value is considered a very special value with unusual semantics, so it's better to know about an OverflowError straight away through an exception, rather than having an inf value silently injected into your calculations.

When to use Preorder, Postorder, and Inorder Binary Search Tree Traversal strategies
...Post-order (C++):
struct Node{
int data;
Node *left, *right;
};
void preOrderPrint(Node *root)
{
print(root->name); //record root
if (root->left != NULL) preOrderPrint(root->left); //traverse left if exists
if (root->right != NULL) preOrde...
When should I use malloc in C and when don't I?
...
Just to clarify, as much as I like this answer (I did give you +1), you can do the same without malloc() by just using a character array. Something like: char some_memory[] = "Hello"; some_memory[0] = 'W'; will also work.

What are the differences between 'call-template' and 'apply-templates' in XSL?
...
This way you give up a little control to the XSLT processor - not you decide where the program flow goes, but the processor does by finding the most appropriate match for the node it's currently processing.
If multiple templates can match a node, the one with the more specific match expression w...
JSON and XML comparison [closed]
...parsers which will change the details to make what I'm saying not quite valid.
JSON is both more compact and (in my view) more readable - in transmission it can be "faster" simply because less data is transferred.
In parsing, it depends on your parser. A parser turning the code (be it JSON or XML)...
What's the difference between window.location= and window.location.replace()?
... it.
See window.location:
assign(url): Load the document at
the provided URL.
replace(url):Replace the current
document with the one at the provided
URL. The difference from the
assign() method is that after using
replace() the current page will not
be saved in session history,...
Expand Python Search Path to Other Source
... a rather large existing code base. We develop in linux and do not use and IDE. We run through the command line. I'm trying to figure out how to get python to search for the right path when I run project modules. For instance, when I run something like:

Tools for analyzing performance of a Haskell program
...d so I know which part of my haskell-program is slow?
Precisely! GHC provides many excellent tools, including:
runtime statistics
time profiling
heap profiling
thread analysis
core analysis.
comparative benchmarking
GC tuning
A tutorial on using time and space profiling is part of Real World H...
What are the disadvantages of using persistent connection in PDO
