var regExp = new RegExp(r"(\w+)"); var str = "Parse my string"; Iterable<Match> matches = regExp.allMatches(str); It's a good idea to use "raw strings" (prefix with r) when writing regular expressions so you can use unescaped backslashes in your expression. ...

We have a C library named my_random that produces random numbers from a custom distribution. It provides two functions that we want to use: set_seed(long seed) and rand() (and many more we do not need). In order to use them in Cython we need to define an interface in the .pxd file and call the f...

DataTables has the capability to enable or disable a number of its features, such as paging or searching. To choose these options, simply select them in your initialization: $(document).ready(function() { $('#tableid').DataTable( { "paging": false, //Turn off paging, all r...

Lambdas are meant to provide inline implementation code for single method interfaces and the ability to pass them around as we have been doing with normal variables. We call them Functional Interface. For example, writing a Runnable in anonymous class and starting a Thread looks like: //Old way n...

The factorial of a number (denoted with !, as for instance 9!) is the multiplication of that number with the factorial of one lower. So, for instance, 9! = 9 x 8! = 9 x 8 x 7! = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1. So in code that becomes, using recursion: long Factorial(long x) { if (x < 1...

Event delegation is a process which allow us to avoid adding event listeners to specific nodes; instead, the event listener is added to parent node. This mechanism utilizes the event propagation/bubbling to handle an event at a higher level element/node in the DOM instead of using the element on whi...
