To scale things, we have to stop using local storage on our server, and start using either a dedicated file storage service or implement a horizontal storage layer. The easiest way to get started with scalable file storage is to use a solution like Filepicker.io, which supports S3, Azure, Rackspace,...

The following scripts are for uploading a file from the server filesystem into the server. Mostly for config files and filewatchers. //https://forums.meteor.com/t/read-file-from-the-public-folder/4910/5 // Asynchronous Method. Meteor.startup(function () { console.log('starting up'); ...

Add React to your project: meteor npm install --save react react-dom react-mounter Create the client/helloworld.jsx file to display a simple React component: import React, { Component } from 'react'; import { mount } from 'react-mounter'; // This component only renders a paragraph containin...

We can also use macros for making code easier to read and write. For example we can implement macros for implementing the foreach construct in C for some data structures like singly- and doubly-linked lists, queues, etc. Here is a small example. #include <stdio.h> #include <stdlib.h>...

def arg = [phrase: 'interpolated'] assert "This is $arg.phrase" == 'This is interpolated'

def str = 'old' def interpolated = "I am the ${str} value" assert interpolated == 'I am the old value' str = 'new' assert interpolated == 'I am the old value'

We can have lazy interpolation in Strings. This is different than normal interpolation as the GString can potentially have different values, depending on the closure, whenever it is converted into a String. def str = 'old' def interpolated = "I am the ${ -> str} value" assert interpo...

def str = 'dsl' def interpolated = "Groovy ${str.length() + 1} easy ${str.toUpperCase()}" assert interpolated == 'Groovy 4 easy DSL' str = 'Domain specific language' assert interpolated == 'Groovy 4 easy DSL'

<style name="AppTheme" parent="Theme.AppCompat"> <item name="android:colorEdgeEffect">@color/my_color</item> </style>

5.0 The ripple animation is shown when user presses clickable views. You can use the same ripple color used by your app assigning the ?android:colorControlHighlight in your views. You can customize this color by changing the android:colorControlHighlight attribute in your theme: This effect colo...

This attribute can change the background of the Status Bar icons (at the top of the screen) to white. <style name="AppTheme" parent="Theme.AppCompat"> <item name="android:windowLightStatusBar">true</item> </style>

The navigation bar (at the bottom of the screen) can be transparent. Here is the way to achieve it. <style name="AppTheme" parent="Theme.AppCompat"> <item name="android:windowTranslucentNavigation">true</item> </style> The Status Bar (t...

5.0 This attribute is used to change the navigation bar (one, that contain Back, Home Recent button). Usually it is black, however it's color can be changed. <style name="AppTheme" parent="Theme.AppCompat"> <item name="android:navigationBarColor">@col...

As well as being able to create an array by filtering out nil from the transformed elements of a sequence, there is also a version of flatMap(_:) that expects the transformation closure to return a sequence S. extension SequenceType { public func flatMap<S : SequenceType>(transform: (Sel...

You can retrieve the implementation defined name of a type in runtime by using the .name() member function of the std::type_info object returned by typeid. #include <iostream> #include <typeinfo> int main() { int speed = 110; std::cout << typeid(speed).name() <...

Dart functions may also be declared anonymously or nested. For example, to create a nested function, just open a new function block within an existing function block void outerFunction() { bool innerFunction() { /// Does stuff } } The function innerFunction may now be us...

Just as you're able to bind data from a view to the model, you can also bind props using the same v-bind directive for passing information from parent to child components. JS new Vue({ el: '#example', data: { msg: 'hello world' } }); Vue.component('child', { props:...

Having your scripts call Raycast directly may lead to problems if you need to change the collision matrices in the future, as you'll have to track down every LayerMask field to accommodate the changes. Depending on the size of your project, this may become a huge undertaking. Encapsulating Raycast ...

Lucene is a Java library. If you don't have a Java development environment set up already, see the Java documentation. Download the latest version of Lucene from the Apache website, and unzip it. Add the required jars to your classpath. The following jars will be required by many projects, inclu...
