Localization and internationalization, what's the difference?
...gs to resource files, enabling the use of date, time and currency formats, etc.
When you wish to sell, for example, a Chinese version of your app, you'd then localize it by hiring a translator to build the zh-CN resource files, and use a new date/time/currency format.

How to know if two arrays have the same values
...n compare their joined strings to see if they have the same members in any order-
var array1= [10, 6, 19, 16, 14, 15, 2, 9, 5, 3, 4, 13, 8, 7, 1, 12, 18, 11, 20, 17];
var array2= [12, 18, 20, 11, 19, 14, 6, 7, 8, 16, 9, 3, 1, 13, 5, 4, 15, 10, 2, 17];
if(array1.sort().join(',')=== array2.sort().jo...
Best approach for GPGPU/CUDA/OpenCL in Java?
...re implemented in CUDA and JNI wrapped (FFT, some linear algebra methods.. etc etc..).
On the other hand OpenCL is just an API. OpenCL kernels are plain strings passed to the API so using OpenCL from Java you should be able to specify your own kernels. OpenCL binding for java can be found here htt...

...t always reversing. The docs for for Guid.ToByteArray() call out the byte order as little endian, and say the constructor matches. The spec for GUID is little endian. I would think that should be independent of the machine byte order.

Which would be better for concurrent tasks on node.js? Fibers? Web-workers? or Threads?
... mean that it lacks things. For a synchronous job (where we can decide the order and way of processing), it works as well as multi-threaded parallelism. For a job that comes from outside like requests to a server, it simply is superior.

What is pseudopolynomial time? How does it differ from polynomial time?
...n the array, while in TSP n refers to the number of nodes in the graph. In order to standardize the definition of what "n" actually means in this context, the formal definition of time complexity defines the "size" of a problem as follows:
The size of the input to a problem is the number of bits...
Purpose of memory alignment
... have the vastly smaller width of the cache line size. This will be on the order of 128 bits.
So:
262,144 bits - size of memory
128 bits - size of bus
Misaligned accesses will occasionally overlap two cache lines, and this will require an entirely new cache read in order to obtain the data. ...
