I have started learning Kitura along the tutorial https://developer.ibm.com/swift/2016/07/06/tutorial-deploying-a-swift-to-do-list-app-to-the-cloud/#comment-2218
I uploaded the files a several time to make the server run (actually the tutorial gave me wrong link for the files)
now it works.
but I saw my Runtime Cost is $289.
[![enter image description here][1]][1]
[![enter image description here][2]][2]
I have not added any support plan
although I have not put my credit card info yet, is that what is going to be charged after Trial or for every month ?
Why am I being charged anyway?
nearly $300 is too high for testing a server.
Would you explain about the Runtime Cost that I am currently being charged please?

<li>Sign up (email, username, password, password_confirmation)</li>
<li>Sign in (email, password)</li>
<li>Sign in using Facebook (automatically sign in if email is exist in db, or create new record then automatically sign in when email is not exist in db)</li>
<li>View articles</li>
<li>Post articles</li>
<li>Edit articles</li>
<li>Delete articles</li>
</ul>
<p>As actions above, <strong>how many services should I break into</strong>? <em>I'm not sure to split every actions in to service like sign-up-service / sign-in-service or group it up as user-service is the right way.</em></p>
<p>An another question, <strong>when I split services separately how can I get articles data with the authors to render on my sites?</strong> <em>Build new broker service which get articles data within article-service then get author data within user-service after that</em>? Or, broker service is no needed, just simply get articles data then author data in my web-application controller.</p>

38,697,656 | Testing Angular2 components that use setInterval or setTimeout | <p>I have a fairly typical, simple ng2 component that calls a service to get some data (carousel items). It also uses setInterval to auto-switch carousel slides in the UI every n seconds. It works just fine, but when running Jasmine tests I get the error: "Cannot use setInterval from within an async test zone".</p>
<p>I tried wrapping the setInterval call in this.zone.runOutsideAngular(() => {...}), but the error remained. I would've thought changing the test to run in fakeAsync zone would solve the problem, but then I get an error saying XHR calls are not allowed from within fakeAsync test zone (which does make sense).</p>
<p>How can I use both the XHR calls made by the service and the interval, while still being able to test the component? I'm using ng2 rc4, project generated by angular-cli. Many thanks in advance.</p>
<p>My code from the component:</p>
<pre><code>constructor(private carouselService: CarouselService) {
}
ngOnInit() {
this.carouselService.getItems().subscribe(items => {
this.items = items;
});
this.interval = setInterval(() => {
this.forward();
}, this.intervalMs);
}
</code></pre>
<p>And from the Jasmine spec: </p>
<pre><code>it('should display carousel items', async(() => {
testComponentBuilder
.overrideProviders(CarouselComponent, [provide(CarouselService, { useClass: CarouselServiceMock })])
.createAsync(CarouselComponent).then((fixture: ComponentFixture<CarouselComponent>) => {
fixture.detectChanges();
let compiled = fixture.debugElement.nativeElement;
// some expectations here;
});
}));

38,700,721 | Reflection with generic syntax fails on a return parameter of an overridden method | <p>To avoid old-fashioned non-generic syntax when searching for attributes of a known type, one usually uses the extension methods in <a href="https://msdn.microsoft.com/en-us/library/system.reflection.customattributeextensions.aspx"><code>System.Reflection.CustomAttributeExtensions</code> class</a> (since .NET 4.5).</p>
<p>However this appears to fail if you search for an attribute on the <em>return parameter</em> of an overridden method (or an accessor of an overridden property/indexer).</p>
<p>I am experiencing this with .NET 4.6.1.</p>
<p>Simple reproduction (complete):</p>
<pre><code>using System;
using System.Reflection;
namespace ReflectionTrouble
{
class B
{
//[return: MyMark("In base class")] // uncommenting does not help
public virtual int M() => 0;
}
class C : B
{
[return: MyMark("In inheriting class")] // commenting away attribute does not help
public override int M() => -1;
}
[AttributeUsage(AttributeTargets.ReturnValue, AllowMultiple = false, Inherited = false)] // commenting away AttributeUsage does not help
sealed class MyMarkAttribute : Attribute
{
public string Descr { get; }
public MyMarkAttribute(string descr)
{
Descr = descr;
}
public override string ToString() => $"MyMark({Descr})";
}
static class Program
{
static void Main()
{
var derivedReturnVal = typeof(C).GetMethod("M").ReturnParameter;
// usual new generic syntax (extension method in System.Refelction namespace):
var attr = derivedReturnVal.GetCustomAttribute<MyMarkAttribute>(); // BLOWS UP HERE, System.IndexOutOfRangeException: Index was outside the bounds of the array.
Console.WriteLine(attr);
// old non-generic syntax without extension method works:
var attr2 = ((MyMarkAttribute[])(derivedReturnVal.GetCustomAttributes(typeof(MyMarkAttribute), false)))[0]; // OK
Console.WriteLine(attr2);
}
}
}
</code></pre>
<p>The code may look "too long to read", but it is really just an overridden method with an attribute on its return parameter and the obvious attempt to retrieve that attribute instance.</p>

<p><a href="https://i.stack.imgur.com/bLkcF.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bLkcF.png" alt="enter image description here"></a></p>
<p>I have an app that is used for clocking in/out. A user goes up to a tablet and selects there name, the data is then inputted into table 'clocktable' as shown above. </p>
<p>What I need to happen is when a user presses their name for a second time (to clock out) it detects that there is already a value in the table with the same employeename value, and moves both clocks to a different table 'oldclocks' so that a record is kept of clocking in/out times. The reason it needs to be in a separate table is I have a web page that displays the 'clocktable' table so we can determine who is in the building.</p>
<p>How can I go about doing this?
I can execute </p>
<pre><code>SELECT DISTINCT EmployeeName, time FROM clocktable ORDER BY EmployeeName
</code></pre>
<p>from within myphp and then execute </p>
<pre><code>INSERT INTO oldclocks SELECT Employeename, Department, time FROM clocktable;
</code></pre>
<p>Afterwards, but I cannot seem to execute them both at the same time in order to get them into a php script. Also is there a way I can delete the select results from the 'clocktable' at the same time? </p>

38,710,904 | How do I resolve the deprecation warning "Method to_hash is deprecated and will be removed in Rails 5.1" | <p>I'm trying to update to Rails 5, I'm getting the following deprecation warning:</p>
<blockquote>
<p>DEPRECATION WARNING: Method to_hash is deprecated and will be removed in Rails 5.1, as <code>ActionController::Parameters</code> no longer inherits from hash. Using this deprecated behavior exposes potential security problems. If you continue to use this method you may be creating a security vulnerability in your app that can be exploited. Instead, consider using one of these documented methods which are not deprecated: <a href="http://api.rubyonrails.org/v5.0.0/classes/ActionController/Parameters.html" rel="noreferrer">http://api.rubyonrails.org/v5.0.0/classes/ActionController/Parameters.html</a> (called from column_header at /Data/Projects/portal/trunk/app/helpers/application_helper.rb:114)</p>
</blockquote>
<p>The line the warning is on looks like this:</p>
<pre><code> link_to(name,
{
action: action_name,
params: params.merge({ order: key, page: nil })
},
{
title: "Sort by this field",
}) +
</code></pre>
<p>As you can see, I'm not calling <code>to_hash</code>. Maybe Rails is. Maybe some other gem is. I have no way to tell, because they didn't think it was worth providing a stack trace. (Pro tip - it usually <em>is</em> worth providing a stack trace!)</p>
<p>So anyway, I followed the link, planning to find a replacement, and <a href="http://api.rubyonrails.org/v5.0.0/classes/ActionController/Parameters.html#method-i-merge" rel="noreferrer">the <code>merge</code> method does not <em>appear</em> to be deprecated</a>, but maybe they simply forgot to document deprecated status, so I can't really be sure.</p>
<p>So what am I supposed to do to clear this?</p>

<pre><code>.EnableSwaggerUi(c =>
{
c.InjectJavaScript(thisAssembly,
typeof(SwaggerConfig).Namespace + ".SwaggerExtensions.custom-js.js");

</code></pre>
<p>The contents of custom-js.js are as follows:</p>
<pre><code>$("#logo").replaceWith("<span id=\"test\">test</span>");
</code></pre>
<p>This works for the most part but the visual is a bit jarring, in that the default swagger header is visible while the page loads and after a brief delay the jquery below kicks and the content of the #logo element is updated</p>
<p>Is there a way to avoid this so that the jquery kicks in as part of the initial load/render and it appears seamless?</p>

38,715,001 | How to make web workers with TypeScript and webpack | <p>I'm having some issues with properly compiling my typescript when I attempt to use web workers. </p>
<p>I have a worker defined like this: </p>
<pre><code>onmessage = (event:MessageEvent) => {
var files:FileList = event.data;
for (var i = 0; i < files.length; i++) {
postMessage(files[i]);
}
};
</code></pre>
<p>In another part of my application i'm using the webpack worker loader to load my worker like this: <code>let Worker = require('worker!../../../workers/uploader/main');</code></p>
<p>I'm however having some issues with making the typescript declarations not yell at me when the application has to be transpiled.
According to my research i have to add another standard lib to my tsconfig file to expose the global variables the worker need access to. These i have specified like so: </p>
<pre><code>{
"compilerOptions": {
"lib": [
"webworker",
"es6",
"dom"
]
}
}
</code></pre>
<p>Now, when i run webpack to have it build everything i get a bunch of errors like these: <code>C:/Users/hanse/Documents/Frontend/node_modules/typescript/lib/lib.webworker.d.ts:1195:13
Subsequent variable declarations must have the same type. Variable 'navigator' must be of type 'Navigator', but here has type 'WorkerNavigator'.</code></p>
<p>So my question is: How do I specify so the webworker uses the lib.webworker.d.ts definitions and everything else follows the normal definitions?</p>

38,716,105 | Angular2 : render a component without its wrapping tag | <p>I am struggling to find a way to do this. In a parent component, the template describes a <code>table</code> and its <code>thead</code> element, but delegates rendering the <code>tbody</code> to another component, like this:</p>
<pre><code><table>
<thead>
<tr>
<th>Name</th>
<th>Time</th>
</tr>
</thead>
<tbody *ngFor="let entry of getEntries()">
<my-result [entry]="entry"></my-result>
</tbody>
</table>
</code></pre>
<p>Each myResult component renders its own <code>tr</code> tag, basically like so:</p>
<pre><code><tr>
<td>{{ entry.name }}</td>
<td>{{ entry.time }}</td>
</tr>
</code></pre>
<p>The reason I'm not putting this directly in the parent component (avoiding the need for a myResult component) is that the myResult component is actually more complicated than shown here, so I want to put its behaviour in a separate component and file.</p>
<p>The resulting DOM looks bad. I believe this is because it is invalid, as <code>tbody</code> can only contain <code>tr</code> elements <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/tbody" rel="noreferrer">(see MDN)</a>, but my generated (simplified) DOM is :</p>
<pre><code><table>
<thead>
<tr>
<th>Name</th>
<th>Time</th>
</tr>
</thead>
<tbody>
<my-result>
<tr>
<td>Bob</td>
<td>128</td>
</tr>
</my-result>
</tbody>
<tbody>
<my-result>
<tr>
<td>Lisa</td>
<td>333</td>
</tr>
</my-result>
</tbody>
</table>
</code></pre>
<p>Is there any way we can get the same thing rendered, but without the wrapping <code><my-result></code> tag, and while still using a component to be sole responsible for rendering a table row ?</p>
<p>I have looked at <code>ng-content</code>, <code>DynamicComponentLoader</code>, the <code>ViewContainerRef</code>, but they don't seem to provide a solution to this as far as I can see.</p>

38,719,887 | How to Do Histogram Equalization in Imagesc's 3 Parameters of Matlab? | Situation: do histogram of the presentation in `imagesc(time,potential,C)` by using `time`, `potetial` and/or `C`; do normalized histogram equalization in the histogram
Proposal: I think `C` is the data for the histogram because `time` and `potential` are just equispaced-equidistant vectors for x- and y-axis, respectively
Code and pseudocode
time=linspace(0,50,100 + 1);
potential=linspace(0,50,100 + 1);
C=gallery('wilk',21); % tridiagonal matrix, eigenvalue problem, Wilkinson 1965
figure, imagesc(time,potential,C);
%% Output: Tridiagonal image
%% Histogram Equalization Pseudocode
% Draw here the histogram of time, potential and/or C
C=histogram_equalization(C,...);
figure, imagesc(time,potential,C);
%% Expected output: tridiagonal image after histogram equalization
Observations
- `C` is not an intensity image because `figure, imhist(C)` returns blank output
- I may need to consider `time` and `potential` also when considering the histogram of `C`. However, they are just equally spaced vectors for the axes so it should not be necessary.
Unsuccessful attempts
- RockTheIT's [code][3] is based on the image handler (`hFig`) or reading .png images. You cannot just put `I=C`, although `I` is a matrix. Why?
- `hist` attempt based on the thread [Difference between hist and imhist][4] gives blank image in `imagesc(x,y,C)` where I am trying to plot all contents of `C` for histogram
C = hist(double(C(:)), 256);
Signal Processing
- Gonzales says the *normalized histogram is given* by $p(r_k) = r_k / M N$, for $k = 0,1,2,...,L-1$ where
- intensity levels ranges in $[0,L-1]$,
- $p(r_k)$ is an estimate of the probability of occurrence of intensity $r_k$ in an image,
- $MN$ is the product of the pixel sizes in `time` and `potential`, respectively
