Answer : Use a binding for the value in your template. value="{{ option.id }}" should be [value]="option.id" And in your selected value use ngModel instead of value . <mat-select [(value)]="selected2"> should be <mat-select [(ngModel)]="selected2"> Complete code: <div> <mat-select [(ngModel)]="selected2"> <mat-option *ngFor="let option of options2" [value]="option.id">{{ option.name }}</mat-option> </mat-select> </div> On a side note as of version 2.0.0-beta.12 the material select now accepts a mat-form-field element as the parent element so it is consistent with the other material input controls. Replace the div element with mat-form-field element after you upgrade. <mat-form-field> <mat-select [(ngModel)]="selected2"> <mat-option *ngFor="let option of options2" [value]="option.id"

Answer : This seems to do the trick: var t = $('html *').contents().map(function() { return (this.type === 'text') ? $(this).text() : ''; }).get().join(' '); console.log(t); Result: One Two Just improved my solution a little bit: var t = $('html *').contents().map(function() { return (this.type === 'text') ? $(this).text()+' ' : ''; }).get().join(''); You can use the TextVersionJS package to generate the plain text version of an html string. You can use it on the browser and in node.js as well. var createTextVersion = require("textversionjs"); var yourHtml = "<h1>Your HTML</h1><ul><li>goes</li><li>here.</li></ul>"; var textVersion = createTextVersion(yourHtml); Download it from npm and require it with Browserify for example. You can use the following function to extract the text from an html separated by a whitespace

Answer : ... a solution for windows: 1) Browse to the VLC folder, e.g. C:\Program Files (x86)\VideoLAN\VLC , and create a new folder called visualizations 2) Download the latest preset_samples of ProjectM, e.g. presets-2.0.0-Source.tar.gz and extract all the .milk files to the visualizations folder created above. 3) In VLC open Preferences from the menu, go to the audio tab and under Output select "Directx audio output" as your Output module. Also make sure that "LibprojectM effect" is selected as your Visualisation. 4) Still in the Preferences menu, click the "All" radiobutton at the bottom left corner. Go to advanced preferences > Audio > Visualizations > projectM and set the "projectM preset path" to C:\Program Files (x86)\VideoLAN\VLC\visualizations 4) Save your preferences, then activate the visualizations by going to the audio menu > visualizations > and select projectM VLC will now begin using random visua

Answer : A great performance improvement can be obtained by declaring the collator object beforehand and using it's compare method. EG: const collator = new Intl.Collator('en', { numeric: true, sensitivity: 'base' }); arrayOfObjects.sort((a, b) => { return collator.compare(a.name, b.name); }); Here's a benchmark script comparing the 3 methods: const arr = []; for (let i = 0; i < 2000; i++) { arr.push(`test-${Math.random()}`); } const arr1 = arr.slice(); const arr2 = arr.slice(); const arr3 = arr.slice(); console.time('#1 - localeCompare'); arr1.sort((a, b) => a.localeCompare( b, undefined, { numeric: true, sensitivity: 'base' } )); console.timeEnd('#1 - localeCompare'); console.time('#2 - collator'); const collator = new Intl.Collator('en', { numeric: true, sensitivity: 'base' }); arr2.sort((a, b) => collator.compare(a, b)); console.timeEnd('#2 - collator'); con

Example: arduino sprintf float // On arduino, sprintf does not support formatting floats, but it can be done // with some simple integer formatting: float f = 3.14; sprintf(str, "Float value: %d.%02d", (int)f, (int)(fabsf(f)*100)%100); // str will now be: "Float value: 3.14"

Answer : You need to also create a ColorStateList for text colors identifying different states. Do the following: Create another XML file in res\color named something like text_color.xml . <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <!-- disabled state --> <item android:state_enabled="false" android:color="#9D9FA2" /> <item android:color="#000"/> </selector> In your style.xml , put a reference to that text_color.xml file as follows: <style name="buttonStyle" parent="@android:style/Widget.Button"> <item name="android:textStyle">bold</item> <item name="android:textColor">@color/text_color</item> <item name="android:textSize">18sp</item> </style> This should resolve your issue. 1.Create a color folder

Answer : Yes you can. Apple provides CloudKit JS, specifically designed for web services. I don't know much about Android, but I'm pretty sure it'll be not a hard challenge to run JavaScript. Also CloudKit WebServices could be interesting for you. EDIT advice and discussion To give you an honest advice: Better use something "own". I currently work with a custom server on an AWS EC2 instance and am really happy. You could, for example, write a really simple server using Node.js and connect a Mongo DB NoSQL database. CloudKit is actually not more than this. This is really a simple task. I did this before and with some JavaScript experience and a few days Node exercises it is absolutely feasible; you'll write really nice servers very quickly. In the end, when dealing with more customers, CloudKit will be more expensive, actually. And if you, why ever, must move to a different service, you will have trouble with CK, because you are not able t

Answer : You can't do clustering with mosquitto. Some other MQTT brokers out there which support clustering, including HiveMQ. HiveMQ has an elastic cluster ability with auto discovery and a distributed masterless architecture and works very well on cloud providers like AWS or Azure. You can see a full list of all brokers which support clustering here. Disclaimer: I'm a developer of HiveMQ, so this answer may be biased. Original source of this answer: Horizontal scaling for brokers. I just added the plugin support. Two functionalities of mosquitto broker combined could be used to setup a n node cluster. Mosquitto bridge support. Plugin support - mosquitto-auth-plug(1) The bridge functionality is used ONLY to synchronize messages between all mosquitto brokers while the mosquitto-auth-plugin could be used to save authorization and ACL in a single database back end. While setting up the bridge, notice the usage of in/out bridge topics to avoid forwarding loop

Answer : Implementation 1 returns the magnitude of the vector that would result from a regular 3D cross product of the input vectors, taking their Z values implicitly as 0 (i.e. treating the 2D space as a plane in the 3D space). The 3D cross product will be perpendicular to that plane, and thus have 0 X & Y components (thus the scalar returned is the Z value of the 3D cross product vector). Note that the magnitude of the vector resulting from 3D cross product is also equal to the area of the parallelogram between the two vectors, which gives Implementation 1 another purpose. In addition, this area is signed and can be used to determine whether rotating from V1 to V2 moves in an counter clockwise or clockwise direction. It should also be noted that implementation 1 is the determinant of the 2x2 matrix built from these two vectors. Implementation 2 returns a vector perpendicular to the input vector still in the same 2D plane. Not a cross product in the classical sense but c

Answer : That division by zero is undefined cannot be proven without math, because it is a mathematical statement. It's like asking "How can you prove that pass interference is a foul without reference to sports?" If you have a definition of "division", then you can ask whether that definition can be applied to zero. For instance, if you define division such that x ÷ y x\div y x ÷ y means "Give the number z z z such that y ⋅ z = x y \cdot z =x y ⋅ z = x ", there is no such number in the standard real number system for y = 0 y=0 y = 0 . If we're required to have that ( x ÷ y ) ⋅ y = x (x\div y) \cdot y=x ( x ÷ y ) ⋅ y = x , then that doesn't work when y y y is equal to zero. In computer languages where x/0 returns an object for which multiplication is defined, you do not have that (x\0)*0 == x . So we can can a class of objects in which we call one of the objects "zero", and have a class method such that "division" by

Answer : Content in md-dialog-content is automatically scrollable. You can manually set the size in the call to MdDialog.open let dialogRef = dialog.open(MyComponent, { height: '400px', width: '600px', }); Further documentation / examples for scrolling and sizing: https://material.angular.io/components/dialog/overview Some colors should be determined by your theme. See here for theming docs: https://material.angular.io/guide/theming If you want to override colors and such, use Elmer's technique of just adding the appropriate css. Note that you must have the HTML 5 <!DOCTYPE html> on your page for the size of your dialog to fit the contents correctly ( https://github.com/angular/material2/issues/2351 ) There are two ways which we can use to change size of your MatDialog component in angular material 1) From Outside Component Which Call Dialog Component import { MatDialog, MatDialogConfig, MatDialogRef } from '@angular/material'
