C++ performance vs. Java/C#
...ters do wonders here.
So depending on what you're writing I would go with one or the other. But if you're writing something that isn't hardware dependent (driver, video game, etc), I wouldn't worry about the performance of C# (again can't speak about Java). It'll do just fine.

You also need to convert that string into a number, this can be done with:
double amount = Double.parseDouble(number);

In this demo, the logic has been moved out of the Activity and into the Fragment. The TitlesFragment actually contains ...
How do you represent a graph in Haskell?
... Knot to get around this, but that makes my brain hurt (because I haven't done much of it yet). I've done more of my substantial programming in Mercury than Haskell so far, and Mercury is strict so knot-tying doesn't help.
Usually when I've run into this before I've just resorted to additional indi...
