35,204,803 | Angular2 and TypeScript: error TS2322: Type 'Response' is not assignable to type 'UserStatus' | <p>I'm playing with Angular2 and TypeScript and it's not going well (this would be so easy in AngularJS). I'm writing a little experiment app to get to grips with it all and I have the following component as my main / top level component...</p>
<pre><code>import {Component, OnInit} from 'angular2/core';
import {RouteConfig, ROUTER_DIRECTIVES} from 'angular2/router';
import {UserData} from './services/user-data/UserData';
import {Home} from './components/home/home';
import {UserStatus} from './types/types.ts';
import {Http, Headers, Response} from 'angular2/http';
@Component({
selector: 'app', // <app></app>
providers: [...FORM_PROVIDERS],
directives: [...ROUTER_DIRECTIVES],
template: require('./app.html')
})
@RouteConfig([
{path: '/', component: Home, name: 'Home'},
// more routes here....
])
export class App {
userStatus: UserStatus;
constructor(public http: Http) {
}
ngOnInit() {
// I want to obtain a user Profile as soon as the code is initialised
var headers = new Headers();
headers.append('Content-Type', 'application/json');
this.http.get('/restservice/userstatus', {headers: headers})
.subscribe(
(data: Response) => {
data = JSON.parse(data['_body']);
this.userStatus = data;
},
err => console.log(err), // error
() => console.log('getUserStatus Complete') // complete
);
}
}
</code></pre>
<p>Now when the top level component is bootstrapped / initialised I want to make a call to a phoney REST service (/restservice/userstatus) I set up that returns an object that I have made into a type like so (this is from <code>import {UserStatus} from './types/types.ts'</code>):</p>
<pre><code>export class UserStatus {
constructor (
public appOS?: any , // can be null
public firstName: string,
public formerName?: any, // can be null
public fullPersId: number,
public goldUser: boolean,
public hasProfileImage: boolean,
public hideMoblieNavigationAndFooter: boolean,
public persId: string,
public profileName: string,
public profilePicture: string,
public showAds: boolean,
public siteId: number,
public url: string,
public verified: boolean
) {
}
}
</code></pre>
<p>Now the <code>appOS</code> and <code>formerName</code> properties could potentially be <code>null</code> and when serving up the response in my REST service they are, the JSON object looks like so:</p>
<pre><code>{
appOS: null,
firstName: "Max",
formerName: null,
fullPersId: 123456789,
goldUser: true,
hasProfileImage: true,
hideMoblieNavigationAndFooter: false,
persId: "4RUDIETMD",
profileName: "Max Dietmountaindew",
profilePicture: "http://myurl.com/images/maxdietmountaindew.jpg",
showAds: true,
siteId: 1,
url: "/profile/maxdietmountaindew",
verified: true
}
</code></pre>
<p>So the data structure sent from my phoney service and the Type Object match however when I try to assign the data from the Rest Service to component in the class <code>'this.userStatus = data;'</code> I get the following error.... </p>
<pre><code>"error TS2322: Type 'Response' is not assignable to type 'UserStatus'.
Property 'appOS' is missing in type 'Response'."
</code></pre>
<p>I assume in my Type class I am doing something wrong with the definition where nulls are concerned can anyone see what I am doing wrong or explain why I am getting the error. Thanks in advance.</p>

35,205,092 | .Net Core and NuGet | <p>I <a href="https://dotnet.github.io/getting-started/">installed .net core from this site</a>. Playing with it led to a number of related package management questions:</p>
<ol>
<li>The <code>dotnet restore</code> command proceeded to "install" .net core NuGet packages. Where were those packages "installed"? A new folder was not created.</li>
<li>The <code>dotnet restore</code> for the "hello world" minimal example required about a hundred NuGet packages, where 99% were presumably irrelevant to the "hello world" app. Granted, a .net native build will remove all that is not needed - but I expected that the <code>restore</code> also would have grabbed very little (three or four packages, not a hundred). Why this behavior?</li>
<li>I created a second "hello world" project and again ran <code>dotnet restore</code>. This time no packages were installed at all. It seems all the packages installed the first time-around went into some global location to be shared. I thought .Net Core didn't work that way. I thought .Net Core projects kept all their dependencies locally. The only framework I targeted was <code>dnxcore50</code>. Why this behavior? </li>
<li>I would like to "uninstall" all these global packages, and try again (just for learning purposes). How might that be accomplished? Remember, as stated in question #1, I don't know where all those files were installed.</li>
<li>Almost all of the packages installed via the <code>restore</code> command were listed as beta. Odd. I thought .Net Core was in RC1, not beta. Confused by this. Why this behavior?</li>
</ol>
<p>I'm also curious of what documentation could/would have explained all this to me. I tried googling for each of these questions, and found nothing (perhaps just horrible google-fu?).</p>

35,206,409 | Elasticsearch 2.1: Result window is too large (index.max_result_window) | <p>We retrieve information from Elasticsearch 2.1 and allow the user to page thru the results. When the user requests a high page number we get the following error message:</p>
<blockquote>
<p>Result window is too large, from + size must be less than or equal

</blockquote>
<p>The elastic docu says that this is because of high memory consumption and to use the scrolling api:</p>
<blockquote>
<p>Values higher than can consume significant chunks of heap memory per

<p>This leaves me with some questions: </p>
<p>1) Would the memory consumption really be lower (any if so why) if I use the scrolling api to scroll up to result 10020 (and disregard everything below 10000) instead of doing a "normal" search request for result 10000-10020?</p>
<p>2) It does not seem that the scrolling API is an option for me but that I have to increase "index.max_result_window". Does anyone have any experience with this?</p>
<p>3) Are there any other options to solve my problem?</p>

35,210,007 | Creating publication-quality geometric figures in Python | <p>I am a mathematician. Recently, I became the editor of the puzzles and problems column for a well-known magazine. Occasionally, I need to create a figure to accompany a problem or solution. These figures mostly relate to 2D (occasionally, 3D) euclidean geometry (lines, polygons, circles, plus the occasional ellipse or other conic section). The goal is obtaining figures of very high quality (press-ready), with Computer Modern ("TeX") textual labels. My hope is finding (or perhaps helping write!) a relatively high-level Python library that "knows" euclidean geometry in the sense that natural operations (e.g., drawing a perpendicular line to a given one passing through a given point, bisecting a given angle, or reflecting a figure A on a line L to obtain a new figure A') are already defined in the library. Of course, the ability to create figures after their elements are defined is a crucial goal (e.g., as Encapsulated Postscript).</p>
<p>I know multiple sub-optimal solutions to this problem (some partial), but I don't know of any that is both simple and flexible. Let me explain:</p>
<ul>
<li><a href="http://asymptote.sourceforge.net/" rel="noreferrer">Asymptote</a> (similar to/based on <a href="https://www.tug.org/metapost.html" rel="noreferrer">Metapost</a>) allows creating extremely high-quality figures of great complexity, but knows almost nothing about geometric constructions (it is a rather low-level language) and thus any nontrivial construction requires quite a long script.</li>
<li><a href="http://www.texample.net/tikz/" rel="noreferrer">TikZ</a> with package <a href="https://www.ctan.org/pkg/tkz-euclide" rel="noreferrer">tkz-euclide</a> is high-level, flexible and also generates quality figures, but its syntax is so heavy that I just cry for Python's simplicity in comparison. (Some programs actually export to TikZ---see below.)</li>
<li>Dynamic Geometry programs, of which I'm most familiar with <a href="http://www.geogebra.org/" rel="noreferrer">Geogebra</a>, often have figure-exporting features (EPS, TikZ, etc.), but are meant to be used interactively. Sometimes, what one needs is a figure based on hard specs (e.g., exact side lengths)---defining objects in a script is ultimately more flexible (if correspondingly less convenient).</li>
<li>Two programs, <a href="http://www.eukleides.org/" rel="noreferrer">Eukleides</a> and <a href="http://poincare.matf.bg.ac.rs/~janicic//gclc/" rel="noreferrer">GCLC</a>, are closest to what I'm looking for: They generate figures (EPS format; GCLC also exports to TikZ). Eukleides has the prettiest, simplest syntax of all the options (see the <a href="http://www.eukleides.org/samples.html" rel="noreferrer">examples</a>), but it happens to be written in C (with source available, though I'm not sure about the license), rather limited/non-customizable, and no longer maintained. GCLC is still maintained but it is closed-source, its syntax is significantly worse than Eukleides's, and has certain other unnatural quirks. Besides, it is not available for Mac OS (my laptop is a Mac).</li>
</ul>
<p>Python has:</p>
<ul>
<li><a href="http://matplotlib.org/" rel="noreferrer">Matplotlib</a>, which produces extremely high-quality figures (particularly of functions or numerical data), but does not seem to know about geometric constructions, and</li>
<li><a href="http://www.sympy.org" rel="noreferrer">Sympy</a> has a geometry module which <em>does</em> know about geometric objects and constructions, all accessible in delightful Python syntax, but seems to have no figure-exporting (or even displaying?) capabilities.</li>

<p>Finally, a question: Is there a library, something like "Figures for Sympy/geometry", that uses Python syntax to describe geometric objects and constructions, allowing to generate high-quality figures (primarily for printing, say EPS)?</p>
<p>If a library with such functionality does not exist, I would consider helping to write one (perhaps an extension to Sympy?). I will appreciate pointers.</p>

35,214,678 | Object Mapping for XML - MOXy Alternative | I've been looking for an object mapper that can use XPath to map variables from one object or an XML web service response to another object. Most preferred approach is through annotations.
The closest I've found is MOXy (https://www.eclipse.org/eclipselink/documentation/2.4/moxy/advanced_concepts005.htm). Here's an example:
@XmlPath("node[@name='first-name']/text()")
private String firstName;
However it doesn't support the xpath 'parent' (http://stackoverflow.com/questions/8404134/eclipselink-moxy-xmlpath-support-for-axes-parent/8405140#8405140) or 'child'(http://stackoverflow.com/questions/9582249/eclipselink-moxy-xpath-selecting-all-child-elements-of-the-current-node-or-all) checks.
ie: this is an example of what I want to be able to do:
XML:
<Customer>
<Field>
<Type>Code</Type>
<Value>abc</Value>
</Field>
<Field>
<Type>Name</Type>
<Value>cde</Value>
</Field>
...
</Customer>
Java
@XmlPath("Customer/Field[child::Type='Code']/Value/text()")
private String CustomerCode;
Does anyone know of alternatives to MOXy that offers xpath support for parent/child checks, or a work around to MOXy for parent/child checks?

35,214,962 | HTML5 video background color not matching background color of website -- in some browsers, sometimes | <p>I have a video that the client wants to sit "seamlessly" in the website. The background HEX color of the video matches the HEX background color of the website, and renders as such in some browsers, some versions, some of the time?</p>
<p>What is most curious is Chrome renders the background of the video differently, until you open the color picker. Then they suddenly match. To be clear, it only fixes it once I open the color picker, not the debugger (read: this not a repainting issue). </p>
<p>Firefox renders differently when I first navigate to the site, but if I hit cmd+r, it becomes perfectly seamless.</p>
<p>Take a look at the screenshots - they say more than I can with words.</p>
<p>I'm in the process of convincing the client to change to white background for the video as that will certainly "fix" it, but I'm super curious as to what /why this is happening.</p>

35,223,032 | How to delegate creation of some classes from Guice injector to another factory? | <p>For instance, RESTEasy's ResteasyWebTarget class has a method <code>proxy(Class<T> clazz)</code>, just like Injector's <code>getInstance(Class<T> clazz)</code>. Is there a way to tell Guice that creation of some classes should be delegated to some instance?</p>
<p>My goal is the following behavior of Guice: when the injector is asked for a new instance of class A, try to instantiate it; if instantiation is impossible, ask another object (e. g. ResteasyWebTarget instance) to instantiate the class.</p>
<p>I'd like to write a module like this:</p>
<pre><code>@Override
protected void configure() {
String apiUrl = "https://api.example.com";
Client client = new ResteasyClientBuilder().build();
target = (ResteasyWebTarget) client.target(apiUrl);
onFailureToInstantiateClass(Matchers.annotatedWith(@Path.class)).delegateTo(target);
}
</code></pre>
<p>instead of</p>
<pre><code>@Override
protected void configure() {
String apiUrl = "https://api.example.com";
Client client = new ResteasyClientBuilder().build();
target = (ResteasyWebTarget) client.target(apiUrl);
bind(Service1.class).toProvider(() -> target.proxy(Service1.class);
bind(Service2.class).toProvider(() -> target.proxy(Service2.class);
bind(Service3.class).toProvider(() -> target.proxy(Service3.class);
}
</code></pre>
<p>I've thought about implementing Injector interface and use that implementation as a child injector, but the interface has too much methods.</p>
<p>I <strong>can</strong> write a method enumerating all annotated interfaces in some package and telling Guice to use provider for them, but that's the backup approach.</p>

35,229,412 | SearchView hints not showing for single character typed | <p>I'm working on an Android application written in Scala that uses <code>android.support.v7.widget.SearchView</code> inside the action bar that's overridden by <code>android.support.v7.widget.Toolbar</code>.</p>
<p>In the app, I need to enable search suggestions for that <code>SearchView</code>. So, every time I detect a query change, I check to see if suggestions need to be updated (code below). If the suggestions need to be updated a call is made to the backend and an <code>android.database.MatrixCursor</code> is created that contains the search suggestions and is set on the <code>SearchView</code>s suggestions adapter (code below).</p>
<p>The problem that I'm having with this is that the search hints will not show up when typing a <strong>single</strong> character. Typing two or more characters in the search box works perfectly. </p>
<p>I've tried with <code>android:searchSuggestThreshold</code> set to <code>0</code> and <code>1</code> in my XML config and I get the same result (like that option being ignored): search hints showing for multiple input characters, but not showing for a single character. </p>
<p>Am I missing something in the config/initialisation of the <code>SearchView</code>? Like an option other than <code>android:searchSuggestThreshold</code> which I can set? I've spent the last few hours on looking for alternative options but couldn't find any.</p>
<p>A possible solution that I see would be getting the <code>AutoCompleteTextView</code> backing the <code>SearchView</code>'s input and setting the threshold for it to 1, but it's an ugly (hack-ish) solution as the <code>AutoCompleteTextView</code> is not exposed by the <code>SearchView</code>s API.</p>
<p>Does anyone know an elegant solution for this? </p>
<p>Thank you!</p>
<p><strong>Detecting search term changes:</strong></p>
<pre><code>//this gets called whenever something is changed in the search box. "s" contains the entire search term typed in the search box
def onQueryTextChange(s: String): Boolean = {
//this checks to see if a call should be made to the backend to update suggestions
SearchSuggestionController.query(s)
//return false as we're not consuming the event
false
}
</code></pre>
<p><strong>Updating search suggestions:</strong></p>
<pre><code>def updateSuggestions(suggestions: Array[String]): Unit = {
val cursor = new MatrixCursor(Array(BaseColumns._ID, SearchManager.SUGGEST_COLUMN_TEXT_1), suggestions.length)
for{
i <- suggestions.indices
s = suggestions(i)

35,232,012 | why this code didn't work corectly? | I have a following probleb to resolve, i don't understand why my code didnt work corectly.
Here is the problem to resolve:
Write a JavaScript function that takes as input an array of two numbers (start and end) and prints at the console a HTML table of 3 columns. The first column should hold a number num, changing from start to end. The second column should hold num*num. The third column should hold "yes" if num is Fibonacci number or "no" otherwise. The table should have header cells titled "Num", "Square" and "Fib". See the below examples.
Input
The input data comes as array of two numbers: start and end. The input data will always be valid and in the format described. There is no need to check it explicitly.
Output
Print at the console the above described table in the same format like the examples below. Don't add additional spaces. Whitespace and character casing are important, so please use the same as in the below examples.
Constraints
• The input is passed to the first JavaScript function found in your code as array of 2 elements.
• The numbers start and end are positive integers in the range [1…1 000 000] and start ≤ end.
• Allowed working time for your program: 0.2 seconds.
• Allowed memory: 16 MB.
This code is not the same by the requirement of problem, but the idea is the same I guess.
Here is my code:
<!-- begin snippet: js hide: false -->
<!-- language: lang-js -->
var fib = [];
var a, b, result;
a = 0;
b = 1;
result = b;
for (var i = 1; i < 31; i++) {
result = a + b;
a = b;
b = result;
fib.push(result);
}
console.log("<table>");
console.log("<tr><th>Num</th><th>Square</th><th>Fib</th></tr>");
var start = 2;
var end = 6;
function isFib(start, end) {
for (i = start; i < end; i++) {
fib.forEach(function (element) {
if (i === element) {
return "yes";
}
else
{
return "no";
}
});
}
}
function buildTable() {
for(var j = start; j < end; j++) {
console.log("<tr><td>" + j + "</td><td>" + j * j + "</td><td>" + isFib(start, end) + "</td></tr>");
}
}
buildTable(start, end);
<!-- end snippet -->
This code is not the same by the requirement of problem, but the idea is same i guess.

35,233,291 | Running a node express server using webpack-dev-server | <p>I'm using webpack to run my react frontend successfully using the following config:</p>
<pre><code>{
name: 'client',
entry: './scripts/main.js',
output: {
path: __dirname,
filename: 'bundle.js'
},
module: {
loaders: [
{
test: /.jsx?$/,
loader: 'babel-loader',
exclude: /node_modules/,
query:{
presets: ['es2015', 'react', 'stage-2']
}
}
]
}
}
</code></pre>
<p>I'm trying to put up a node.js express backend as well, and would like to run that through webpack as well, so that I have a single server running both the backend and frontend, and because I want to use babel to transpile my javascript.</p>
<p>I made a quick testserver looking like this:</p>
<pre><code>var express = require('express');
console.log('test');
var app = express();
app.get('/', function(req, res){
res.send("Hello world from Express!!");
});
app.listen(3000, function(){
console.log('Example app listening on port 3000');
});
</code></pre>
<p>If I run this with <code>node index.js</code> and open my browser on <code>localhost:3000</code> it prints "Hello world from Express!!". So far so good. Then I tried creating a web-pack config for it:</p>
<pre><code>var fs = require('fs');
var nodeModules = {};
fs.readdirSync('node_modules')
.filter(function(x) {
return ['.bin'].indexOf(x) === -1;
})
.forEach(function(mod) {
nodeModules[mod] = 'commonjs ' + mod;
});
module.exports = [
{
name: 'server',
target: 'node',
entry: './index.js',
output: {
path: __dirname,
filename: 'bundle.js'
},
externals: nodeModules,
module: {
loaders: [
{
test: /\.js$/,
loaders: [
'babel-loader'
]
},
{
test: /\.json$/,
loader: 'json-loader'
}
]
}
}
</code></pre>
<p>When I run the command <code>webpack-dev-server</code> it starts up successfully (it seems). However, if I go to my browser on <code>localhost:3000</code> now, it just says that the webpage is not available, just as when the server is not running at all.</p>
<p>I'm very new to both node and webpack, so either I have made a small mistake somewhere, or I'm way off ;)</p>

35,233,989 | AutoMapper 4.2 and Ninject 3.2 | <p>I'm updating a project of mine to use AutoMapper 4.2, and I'm running into breaking changes. While I <em>seem</em> to have resolved said changes, I'm not entirely convinced I've done so in the most appropriate way.</p>
<p>In the old code, I have a <code>NinjectConfiguration</code>, and an <code>AutoMapperConfiguration</code> class that are each loaded by WebActivator. In the new version the <code>AutoMapperConfiguration</code> drops out and I instead instance a <code>MapperConfiguration</code> directly in the <code>NinjectConfiguration</code> class where the bindings are happening, like so:</p>
<pre><code>private static void RegisterServices(
IKernel kernel) {
var profiles = AssemblyHelper.GetTypesInheriting<Profile>(Assembly.Load("???.Mappings")).Select(Activator.CreateInstance).Cast<Profile>();
var config = new MapperConfiguration(
c => {
foreach (var profile in profiles) {
c.AddProfile(profile);
}
});
kernel.Bind<MapperConfiguration>().ToMethod(
c =>
config).InSingletonScope();
kernel.Bind<IMapper>().ToMethod(
c =>
config.CreateMapper()).InRequestScope();
RegisterModules(kernel);
}
</code></pre>
<p>So, is this the appropriate way of binding AutoMapper 4.2 using Ninject? It seems to be working so far, but I just want to make sure.</p>
