For some reason you develop a new version of com.stackoverflow (say version 1.1), then you should: Create folder com/stackoverflow/1.1 on ${WILDFLY_HOME}/modules Put the new jar on last dir Create file module.xml on last dir with the following content <?xml version="1.0" encodin...

By default modules are placed on ${WILDFLY}/modules directory but you can have more directories with modules, just edit your standalone.conf (or standalone.conf.bat if you are on Microsoft Windows) and properly set the variable JBOSS_MODULEPATH For example in Unix/Linux/MacOSX: JBOSS_MODULEPATH=&q...

A common mistake is to forget surrounding compound function arguments with parentheses, leading to type errors. # string_of_int 1+1;; Error: This expression has type string but an expression was expected of type int This is because of the precedence. In fact, the above evaluates to # (string...

The redis-py client provides two classes StrictRedis and Redis to establish a basic connection to a Redis database. The Redis class is provided for backwards compatibility and new projects should use the StrictRedis class. One of the recommended ways to establish a connection, is to define the con...

Note: The output.library and name (in DllPlugin) must be the same. const path = require('path'); const webpack = require('webpack'); const ExtractTextPlugin = require('extract-text-webpack-plugin'); const extractCSS = new ExtractTextPlugin('vendor.css'); const isDevelopment = process.env.NODE_E...

The keyword function can be used to initiate pattern-matching on the the last argument of a function. For example, we can write a function called sum, which computes the sum of a list of integers, this way let rec sum = function | [] -> 0 | h::t -> h + sum t ;; val sum : int list -&...

For this example, we will used 4 bodies and will show only the last 8 bits of the bit masks for simplicity. The 4 bodies are 3 SKSpriteNodes, each with a physics body and a boundary: let edge = frame.insetBy(dx: 0, dy: 0) physicsBody = SKPhysicsBody(edgeLoopFrom: edge) Note that the 'ed...

If you have an Arduino connected to a computer or a Raspberry Pi, and want to send data from the Arduino to the PC you can do the following: Arduino: void setup() { // Opens serial port, sets data rate to 9600 bps: Serial.begin(9600); } void loop() { // Sends a line over serial: Se...

Redis allow you to use the String data type to store floating point numbers. A user can set the float value of a key using the command: SET floatkey 2.0 The set command will create the key if necessary or update it if it already exists. The value of the key can be updated on the server using e...
