Why doesn't Java offer operator overloading?
....
In Java, as in C++, or whatever language, the programmer must respect a minimum of semantics when writing code. This means implementing a add function that adds, and Cloneable implementation method that clones, and a ++ operator than increments.
What's obfuscating anyway?
Now that we know that ...

use 30 min as default for my application.
add a 'minimum distance to last known location' check. without this, your points
will "jump around" when GPS is not available and the location is being triangulated
from the cell towers. or you can check if the new location is outs...
How can I improve my paw detection?
... would be formed, so you have distinct objects. Then, each "object" has a minimum and maximum x and y value, so bounding boxes can be packed neatly around them.
Pseudocode:
(MARK) ALL PIXELS ABOVE (0.5)
(MARK) ALL PIXELS (ADJACENT) TO (MARK) PIXELS
REPEAT (STEP 2) (5) TIMES
SEPARATE EACH TOTAL...
How efficient is locking an unlocked mutex? What is the cost of a mutex?
...
This depends on what you actually call "mutex", OS mode and etc.
At minimum it's a cost of an interlocked memory operation. It's a relatively heavy operation (compared to other primitive assembler commands).
However, that can be very much higher. If what you call "mutex" a kernel object (i.e...

Is there a list of screen resolutions for all Android based phones and tablets? [closed]
...outs, you will need to decide how to handle the odd "in-between" screens.
Minimum "portrait mode" solution is to support 1.3333, which results in unused space at top and bottom, on all the resolutions with larger aspect ratio.
Most likely, you would instead design it to stretch over the 1.333 to 1....

What is the optimal algorithm for the game 2048?
... least once:
2048: 100%
4096: 100%
8192: 100%

The minimum score over all runs was 124024; the maximum score achieved was 794076. The median score is 387222. The AI never failed to obtain the 2048 tile (so it never lost the game even once in 100 games); in fact, it achieved t...

He notes that this operation is optimal (does the minimum number of arithmetic or logical operations) for all b < 15. Also there is no known solution to the general problem of finding an optimal sequence of factors to compute a^b for any b other than an extensive search....
