Is there a best practice for generating html with javascript
...nce seen in the first method is likely because the result string must be reallocated 200 times, and memory allocations can be slow. After two iterations you have "testingtesting". After three iterations, that string is thrown away and memory with enough room for "testingtestingtesting" is allocate...
Quickly create large file on a Windows system
...oftware/rdfc/index-en.html
RDFC is probably not the fastest, but it does allocate data blocks. The absolutely fastest would have to use lower level API to just obtain cluster chains and put them into MFT without writing data.
Beware that there's no silver bullet here - if "creation" returns insta...
What is the memory consumption of an object in Java?
... tell you, so long as the program gives the same answers.
It might allocate some temporary Objects on the stack.
It may optimize some variables or method calls totally out of existence replacing them with constants.
It might version methods or loops, i.e. compile two versions of a meth...
How do I concatenate two strings in C?
....h>
char* concat(const char *s1, const char *s2)
{
char *result = malloc(strlen(s1) + strlen(s2) + 1); // +1 for the null-terminator
// in real code you would check for errors in malloc here

What does immutable mean?
...ed in will not be modified. Once you create a string "foo", some memory is allocated to store the value "foo". This memory will not be altered. If you modify the string with, say, substr(1), a new string is created and a different part of memory is allocated which will store "oo". Now you have two s...
iOS: How to get a proper Month name from a number?
...nt monthNumber = 11; //November
NSDateFormatter *df = [[[NSDateFormatter alloc] init] autorelease];
NSString *monthName = [[df monthSymbols] objectAtIndex:(monthNumber-1)];
Note that you'll need to subtract 1 from your 1..12 monthNumber since monthSymbols is zero-based.

Advantages of Binary Search Trees over Hash Tables
... instance, if a hash function has a range R(h) = 0...100, then you need to allocate an array of 100 (pointers-to) elements, even if you are just hashing 20 elements. If you were to use a binary search tree to store the same information, you would only allocate as much space as you needed, as well as...
