Doc is an interface and the Java Print Service API provide a simple implementation called SimpleDoc. Every Doc instance is basically made of two aspects: the print data content itself (an E-mail, an image, a document etc) the print data format, called DocFlavor (MIME type + Representation class...

This example illustrates how Go's type system can be used to implement some unit system. package main import ( "fmt" ) type MetersPerSecond float64 type KilometersPerHour float64 func (mps MetersPerSecond) toKilometersPerHour() KilometersPerHour { return KilometersPer...

We’ll first go over gaze-based interactions. Gaze-based interactions rely on rotating our heads and looking at objects to interact with them. This type of interaction is for headsets without a controller. Even with a rotation-only controller (Daydream, GearVR), the interaction is still similar. Sinc...

To use Processing in Eclipse, start by creating a new Java project. Then, select File > Import and then choose General > File System to locate the core.jar file. It can be found in PATH_TO_PROCESSING/core/library/ for Windows or /Applications/Processing 3.app/Contents/Java/core/library/ for Ma...

If you have: val r = Random(233) infix inline operator fun Int.rem(block: () -> Unit) { if (r.nextInt(100) < this) block() } You can write the following DSL-like code: 20 % { println("The possibility you see this message is 20%") }

Similar to the previous example, here, a sine and a cosine curve are plotted on the same figure using separate plot commands. This is more Pythonic and can be used to get separate handles for each plot. # Plotting tutorials in Python # Adding Multiple plots by superimposition # Good for plots sha...

Fixed-width files are text files in which columns are not separated by any character delimiter, like , or ;, but rather have a fixed character length (width). Data is usually padded with white spaces. An example: Column1 Column2 Column3 Column4Column5 1647 pi 'important' ...

ImageMagick includes a number of command-line utilities for manipulating images. Here we will use compare command-line tool. compare tool is very useful. Suppose you want to test (e.g. layout, color, icons etc.) the difference between your expected design UI HTML file with actual result of JSP...

pry is a powerful tool that can be used to debug any ruby application. Setting up a ruby-on-rails application with this gem is very easy and straightforward. Setup To start debugging your application with pry Add gem 'pry' to the application's Gemfile and bundle it group :development, :test ...

As recently Apple rolled out iOS11 and Xcode-9, we can now debug apps on devices without connecting devices to Xcode through USB. We can take advantage of wireless debugging feature added to this Xcode-9. To enable wireless debugging, we have to configure some steps in Xcode. 1 First connect the ...

In order to trigger a "upgradeneeded" event you need to request the database with version higher than the current version - otherwise the event won't be triggered. function createTable(dbName, dbversion, tableName) { var request = indexedDB.open(dbName, dbversion); request.onupgrade...

This is a more generic solution applicable in system where the user has option to add indexes to the table that he uses: function createTable(dbName, tableName) { var request = indexedDB.open(dbName); request.onsuccess = function (e){ var database = e.target.result; var version = p...

Node js code Sample to start this topic is Node.js server communicating with Arduino via serialport. npm install express --save npm install serialport --save Sample app.js: const express = require('express'); const app = express(); var SerialPort = require("serialport"); var po...

Suppose we have this source file that we would like to split: cat -n sourcefile 1 On the Ning Nang Nong 2 Where the Cows go Bong! 3 and the monkeys all say BOO! 4 There's a Nong Nang Ning 5 Where the trees go Ping! 6 And the tea pots jibber jabber joo. 7 On the Nong Ning Nang Comma...

To install PLY on your machine for python2/3, follow the steps outlined below: Download the source code from here. Unzip the downloaded zip file Navigate into the unzipped ply-3.10 folder Run the following command in your terminal: python setup.py install If you completed all the above, you...

Let's demonstrate the power of PLY with a simple example: this program will take an arithmetic expression as a string input, and attempt to solve it. Open up your favourite editor and copy the following code: from ply import lex import ply.yacc as yacc tokens = ( 'PLUS', 'MINUS', ...

There are two steps that the code from example 1 carried out: one was tokenizing the input, which means it looked for symbols that constitute the arithmetic expression, and the second step was parsing, which involves analysing the extracted tokens and evaluating the result. This section provides a ...

This section explains how the tokenized input from Part 1 is processed - it is done using Context Free Grammars (CFGs). The grammar must be specified, and the tokens are processed according to the grammar. Under the hood, the parser uses an LALR parser. # Yacc example import ply.yacc as yacc ...
