Are Javascript arrays sparse?
... you actually get a dense array if you say something like foo = new Array(10000). However, this is supposed to work: foo = Array.apply(null, {length: 10});.

How to fix java.net.SocketException: Broken pipe?
...In the following case, I create a Socket server that listen at TCP port 10_000 and accept max 200 pending sockets.
new Thread(() -> {
try (ServerSocket serverSocket = new ServerSocket(10_000, 200)) {
logger.info("Server starts listening on TCP port {}", port);
while (true)...
How to convert a string into double and vice versa?
..., because different locales format numbers differently. Some will write "1000" for one thousand, while others will write "1,000" and others "1.000" - which do you get from -[NSString doubleValue]?

What are the differences between the threading and multiprocessing modules?
...h a naive use of thread I halved the speed of my code (starting more than 1000 threads at the same time, each calling an external app.. this saturates the cpu, yet there is a x2 increase in speed). I think managing the thread smartly might really improve the speed of my code..

How to get the mouse position without events (without moving the mouse)?
...age with a div that covers the whole document. Inside that, create (say) 2,000 x 2,000 <a> elements (so that the :hover pseudo-class will work in IE 6, see), each 1 pixel in size. Create a CSS :hover rule for those <a> elements that changes a property (let's say font-family). In your loa...
Collect successive pairs from a stream
...
Now you can limit your stream to the length you want
pairStream.limit(1_000_000).forEach(i -> System.out.println(i));
P.S. I hope there is better solution, something like clojure (partition 2 1 stream)

Is there a rule-of-thumb for how to divide a dataset into training and validation sets?
...going to give you satisfactory variance in your estimates. If you have 100,000 instances, it doesn't really matter whether you choose an 80:20 split or a 90:10 split (indeed you may choose to use less training data if your method is particularly computationally intensive).
Assuming you have enough ...

Very large matrices using Python and NumPy
... I've found that it's capable of handling matrices which are quite large (10000 x 10000) easily, but begins to struggle with anything much larger (trying to create a matrix of 50000 x 50000 fails). Obviously, this is because of the massive memory requirements.

Random color generator

Use getRandomColor() in place of "#0000FF":
function getRandomColor() {
var letters = '0123456789ABCDEF';
var color = '#';
for (var i = 0; i < 6; i++) {
color += letters[Math.floor(Math.random() * 16)];
}
return color;
