How do I call a dynamically-named method in Javascript?
...properties may be accessed as though the object were an associative array, and that all global objects are actually properties of the window host object.
var method_name = "Colours";

What is thread safe or non-thread safe in PHP?
...ncy approaches:
Different web servers implement different techniques for handling incoming HTTP requests in parallel. A pretty popular technique is using threads -- that is, the web server will create/dedicate a single thread for each incoming request. The Apache HTTP web server supports multiple m...
How to understand Locality Sensitive Hashing?
...mmds/ch3a.pdf
Also I recommend the below slide:
http://www.cs.jhu.edu/%7Evandurme/papers/VanDurmeLallACL10-slides.pdf .
The example in the slide helps me a lot in understanding the hashing for cosine similarity.

map function for objects (instead of arrays)
...For that matter I wanted to add another solution that returns a new object and leaves the original object as it is:
var myObject = { 'a': 1, 'b': 2, 'c': 3 };

return Object.k...

Can you make just part of a regex case-insensitive?
...e minus sign will be turned off. E.g. (?i-sm) turns on case insensitivity, and turns off both single-line mode and multi-line mode.
Not all regex flavors support this. JavaScript and Python apply all mode modifiers to the entire regular expression. They don't support the (?-ismx) syntax, since turn...
How to get index of object by its property in JavaScript?
...e array is probably the best way. But I would put it in it's own function, and make it a little more abstract:
function findWithAttr(array, attr, value) {
for(var i = 0; i < array.length; i += 1) {
if(array[i][attr] === value) {
return i;
}
}
return -1;
}
