To discovery the default print service, we can use the PrintServiceLookup class. Let's see how:: import javax.print.PrintService; import javax.print.PrintServiceLookup; public class DiscoveringDefaultPrintService { public static void main(String[] args) { discoverDefaultPrintSer...

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...

The cursor builds on top of and depends on the raycaster component. If we want to customize the raycasting pieces of the cursor, we can do by changing the raycaster component properties. Say we want set a max distance, check for intersections less frequently, and set which objects are clickable: &l...

When the active property gets toggled, the component will notify the camera system to change the current camera used by the renderer: var secondCameraEl = document.querySelector('#second-camera'); secondCameraEl.setAttribute('camera', 'active', true);

To fix entities onto the camera such that they stay within view no matter where the user looks, you can attach those entities as a child of the camera. Use cases might be a heads-up display (HUD). <a-entity camera look-controls> <a-entity geometry="primitive: plane; height: 0.2; wi...

To position the camera, set the position on a wrapper . Don’t set the position directly on the camera primitive because controls will quickly override the set position: <a-entity position="0 0 5"> <a-camera></a-camera> </a-entity>

The recommended way is to write a component, and attach it to the scene element. The scene and its children will be initialized before this component. AFRAME.registerComponent('do-something', { init: function () { var sceneEl = this.el; } }); <a-scene do-something></a-scene...

$logger = $container->get('logger'); This will fetch the service with the service ID "logger" from the container, an object that implements Psr\Log\LoggerInterface.

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...

You will need to install node.js - https://nodejs.org/en/ npm install -g @angular/cli - install the CLI by executing this command in the terminal ng new projectname - after executing this command in the terminal, you will create a new sub folder titled projectname in your current folder. cd pro...

In this example, a sine curve and a cosine curve are plotted in the same figure by superimposing the plots on top of each other. # Plotting tutorials in Python # Adding Multiple plots by superimposition # Good for plots sharing similar x, y limits # Using single plot command and legend import...

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...

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...

Given a rod of length n inches and an array of length m of prices that contains prices of all pieces of size smaller than n. We have to find the maximum value obtainable by cutting up the rod and selling the pieces. For example, if length of the rod is 8 and the values of different pieces are given ...

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', ...

Use nic to create a new project Enter this command in your terminal $THEOS/bin/nic.pl NIC 2.0 - New Instance Creator ------------------------------ [1.] iphone/activator_event [2.] iphone/application_modern [3.] iphone/cydget [4.] iphone/flipswitch_switch [5.] iphone/framework ...

You can define the layer parameters in the prototxt by using param_str. Once you've done it, here is an example on how you access these paremeters inside the layer class: def setup(self, bottom, top): params = eval(self.param_str) param1 = params["param1"] param2 = params.g...

The goal of backpropagation is to optimize the weights so that the neural network can learn how to correctly map arbitrary inputs to outputs. Each layer has its own set of weights, and these weights must be tuned to be able to accurately predict the right output given input. A high level overview ...

from urllib.request import urlopen from collections import Counter import re conn = urlopen('http://textfiles.com/100/dodontae.hum') lines = conn.readlines() conn.close() # readlines() returns byte strings data = ''.join([line.decode('utf-8') for line in lines]) # replace non-letters ...

You can use TO_CHAR( date_value, 'D' ) to get the day-of-week. However, this is dependent on the NLS_TERRITORY session parameter: ALTER SESSION SET NLS_TERRITORY = 'AMERICA'; -- First day of week is Sunday SELECT TO_CHAR( DATE '1970-01-01', 'D' ) FROM DUAL; Outputs 5 ALTER SESSION SET ...
