How can I determine whether a 2D Point is within a Polygon?
...at the end has been discussed in the article referred above.
vertx, verty: Arrays containing the x- and y-coordinates of the polygon's vertices.
testx, testy: X- and y-coordinate of the test point.
It's both short and efficient and works both for convex and concave polygons. As suggested before, y...
How to convert number to words in java
...ave a crude mechanism to convert numbers to words (e.g. using a few static arrays) and based on the size of the number translating that into an english text. But we are running into issues for numbers which are huge.

What is an optional value in Swift?
...thod which can return a value or nothing, like searching for a match in an array
A method which can return either a result or get an error and return nothing, like trying to read a file's contents (which normally returns the file's data) but the file doesn't exist

How to generate a random string of a fixed length in Go?
...):
You can use the crypto/rand package that supports reading random byte arrays (from /dev/urandom) and is geared towards cryptographic random generation. see http://golang.org/pkg/crypto/rand/#example_Read . It might be slower than normal pseudo-random number generation though.
Take a random num...

... with one line; grab a reference to the Document folder without ridiculous array spelunking (an app has one docs folder, always in the same place - why all the extra work to "find" it?); use the .Net framework where Cocoa stinks (NSDate, anyone?); use commodity skills for enterprise apps; use proper...

What Every Programmer Should Know About Memory?
...ry other for 256b AVX1/AVX2, which often doesn't slow down looping over an array that wasn't in L1D.
Unaligned load instructions have zero penalty if the address is aligned at runtime, but compilers (especially gcc) make better code when autovectorizing if they know about any alignment guarantees. ...
Fastest way to determine if an integer's square root is an integer
...n-squares quickly. It uses a 64-item table packed in a long, so there's no array access cost (indirection and bounds checks). For a uniformly random long, there's a 81.25% probability of ending here.
The second test catches all numbers having an odd number of twos in their factorization. The method ...
What kinds of patterns could I enforce on the code to make it easier to translate to another program
.... For example, Python has lists and dictionaries, while PHP only has assoc arrays.
The "learner" approach is to build something that works OK for a restricted subset of the language (such as only print statements, simple math, and variable assignment), and then progressively remove limitations. Tha...
