What is stack unwinding?
...
Stack unwinding is usually talked about in connection with exception handling. Here's an example:
void func( int x )
{
char* pleak = new char[1024]; // might be lost => memory leak
std::string s( "hello world" ); // will be properly de...
Performing Breadth First Search recursively
...tion, but I suppose I could imagine some bizarre scenario where you're not allowed any heap space for some reason [some really bad custom memory manager? some bizarre runtime/OS issues?] while you still have access to the stack...)
Breadth-first traversal traditionally uses a queue, not a stack. T...
Fastest Way of Inserting in Entity Framework
...avingChanges (for each
record)..."
That's the worst thing you can do! Calling SaveChanges() for each record slows bulk inserts extremely down. I would do a few simple tests which will very likely improve the performance:
Call SaveChanges() once after ALL records.
Call SaveChanges() after for e...

Functional programming - is immutability expensive? [closed]
...’d like to clarify some points.
The “in-place” quicksort isn’t really in-place (and quicksort is not by definition in-place). It requires additional storage in the form of stack space for the recursive step, which is in the order of O(log n) in the best case, but O(n) in the worst case.
Im...

git checkout -b waldo-svn remotes/waldo
The -svn suffix is to avoid warnings of the ...
How was the first compiler written?

Assembly instructions are (generally) a direct mapping to opcodes, which are (multi-)byte values of machine code that can be directly interpreted by the processor. It is quite possible to write a program in opcodes directly by looking them up from a table (...
