Looking for a good world map generation algorithm [closed]
...andom motion vector, and should be capable of determining earthquake zones vs volcanic zones, etc. Each point of land would then end up with an individual vector based off its location in relation to the plate boundaries, and should end up with a fairly realistic simulation to work from.

What's the use of Jade or Handlebars when writing AngularJs apps
... I agree with @NickWiggill. Mentally parsing a JADE template vs. raw HTML requires equal 'wetware' cpu time for me. I won't go so far as to say you're unprofessional if you disagree, but to me it's the same thing. @ Philipp, your analogy of parsing C/C++ to assembly being equal to pa...

Why is SSE scalar sqrt(x) slower than rsqrt(x) * x?
...
This is also true for division. MULSS(a,RCPSS(b)) is way faster than DIVSS(a,b). In fact it's still faster even when you increase its precision with a Newton-Raphson iteration.
Intel and AMD both recommend this technique in their optimisation manuals. In applications which don't require IEEE-...
What is the memory consumption of an object in Java?
...ider a class like this:
public class SingleByte
{
private byte b;
}
vs
public class OneHundredBytes
{
private byte b00, b01, ..., b99;
}
On a 32-bit JVM, I'd expect 100 instances of SingleByte to take 1200 bytes (8 bytes of overhead + 4 bytes for the field due to padding/alignment). I'...

What is the most accurate way to retrieve a user's correct IP address in PHP?
...would take form of forwarded_for.
Also i didnt see anyone address isset() vs !empty() -- its possible to enter nothing for x_forwarded_for yet still trigger isset() truth resulting in blank var, a way to get around is to use && and combine both as conditions. Keep in mind you can spoof word...
