Does a javascript if statement with multiple conditions test all of them?
...bles, each function may take a long time, and not only is it important to know this short circuits, but in what order. For example:

When should you use constexpr capability in C++11?
...t b ) { return a * b; }
const int meaningOfLife = MeaningOfLife( 6, 7 );
Now you have something that can be evaluated down to a constant while maintaining good readability and allowing slightly more complex processing than just setting a constant to a number.
It basically provides a good aid to ma...
Parse usable Street Address, City, State, Zip from a string [closed]
...cademic to write it, there's no weirdness, just lots of string handling.
(Now that you've posted some sample data, I've made some minor changes)
Work backward. Start from the zip code, which will be near the end, and in one of two known formats: XXXXX or XXXXX-XXXX. If this doesn't appear, you ca...
Get Base64 encode file-data from Input Form
...at, but it's here if you want to take a look; it's pretty neat.
What I do now:

SQlite Getting nearest locations (with latitude and longitude)
...w PointF((float) lat, (float) lon);
return newPoint;
}
And now create your query:
PointF center = new PointF(x, y);
final double mult = 1; // mult = 1.1; is more reliable
PointF p1 = calculateDerivedPosition(center, mult * radius, 0);
PointF p2 = calculateDerivedPosition(center, mul...
Why is my variable unaltered after I modify it inside of a function? - Asynchronous code reference
...being assigned or passed as an argument. That is what we call a callback.
Now the question is, when is that callback called?
It depends on the case. Let's try to trace some common behavior again:
img.onload may be called sometime in the future, when (and if) the image has successfully loaded.

Sass or Compass without ruby?

Sass was originally written for Ruby, but now they've created libSass which is a C/C++ port of the Sass engine, which makes it easier to integrate the engine into an IDE or another language. At this point, you can use the Sass engine in Ruby, Node.js, Python, PHP, Ja...
