How are software license keys generated?
... Additionally, it requires online activation.
The full algorithm is rather complex, but outlined nicely in this (completely legal!) paper, published in Germany.
Of course, no matter what you do, unless you are offering an online service (like World of Warcraft), any type of copy protection is just ...
What's the best way to put a c-struct in an NSArray?
...ort CoreGraphics structures – you can use it for your own too. I would recommend doing so, as the class is probably lighter weight than NSData for simple data structures.
Simply use an expression like the following:
[NSValue valueWithBytes:&p objCType:@encode(Megapoint)];
And to get the va...
Differences between lodash and underscore [closed]
...pport for arrays, strings, objects, and arguments objects1. It has since become a superset of Underscore, providing more consistent API behavior, more features (like AMD support, deep clone, and deep merge), more thorough documentation and unit tests (tests which run in Node, Ringo, Rhino, Narwhal, ...
Regular expression that matches valid IPv6 addresses
...lar expression that matches valid IPv6 addresses, including those in their compressed form (with :: or leading zeros omitted from each byte pair).
...
Declaring variables inside or outside of a loop
...laring it inside the while loop would not be an option, since it would not compile.
So, since str is not used outside the loop, the smallest possible scope for str is within the while loop.
So, the answer is emphatically that str absolutely ought to be declared within the while loop. No ifs, no an...
Do you put unit tests in same project or another project?
...10) isn't a con.
Edit: More Info On Build and Shipping
I would further recommend that any automated build process place production and unit tests into different locations. Ideally, the unit test build process only runs if the production code builds, and copies the product files into the unit test...

Why are private fields private to the type, not the instance?
...
I think one reason it works this way is because access modifiers work at compile time. As such, determining whether or not a given object is also the current object isn't easy to do. For example, consider this code:
public class Foo
{
private int bar;
public void Baz(Foo other)
{

std::string formatting like sprintf
...ave write access to the underlying buffer (until C++11; see Dietrich Epp's comment). You'll have to do it first in a c-string, then copy it into a std::string:
char buff[100];
snprintf(buff, sizeof(buff), "%s", "Hello");
std::string buffAsStdStr = buff;
But I'm not sure why you wouldn't jus...
