Enables a code to be statically compiled. Its bytecode will be closer to Java's, thus having better performance, though some dynamic features won't be available. @groovy.transform.CompileStatic class ListMath { def countSize(List<String> strings) { strings.collect { it.size() }...

A common mistake for Java beginners is to use the == operator to test if two strings are equal. For example: public class Hello { public static void main(String[] args) { if (args.length > 0) { if (args[0] == "hello") { System.out.println(&q...

In Object Oriented Programming a common task is to compose objects (values). In Functional Programming it is as common task to compose values as well as functions. We are used to compose values from our experience of other programming languages using operators like +, -, *, / and so on. Value co...

If you wish to make a complete backup of a large MySql installation and do not have sufficient local storage, you can dump and compress it directly to an Amazon S3 bucket. It's also a good practice to do this without having the DB password as part of the command: mysqldump -u root -p --host=localho...

CommonJS is a popular modularization pattern that's used in Node.js. The CommonJS system is centered around a require() function that loads other modules and an exports property that lets modules export publicly accessible methods. Here's an example of CommonJS, we'll load Lodash and Node.js' fs m...

In F# there are many options for creating data pipelines, for example: List, Seq and Array. What data pipeline is preferable from memory usage and performance perspective? In order to answer this we'll compare performance and memory usage using different pipelines. Data Pipeline In order to me...

A process can (try to) send a signal to any other process using the kill() function. To do so, the sending process needs to known the receiving process' PID. As, without introducing a race, a process can only be sure of its own PID (and the PIDs of its children) the most simple example to demonstra...

Function composition allows for two functions to operate and be viewed as a single function. Expressed in mathematical terms, given a function f(x) and a function g(x), the function h(x) = f(g(x)). When a function is compiled, it is compiled to a type related to Function1. Scala provides two method...

Inline display elements, usually such as span or a, will include up to one white-space character before and after them in the document. In order to avoid very long lines in the markup (that are hard to read) and unintentional white-space (which affects formatting), the white-space can be commented o...
