the zone does not have enough resources available to fulfill the request/ the resource is not ready : <p>I failed to start my instance (through the web browser), it gave me the error: </p>
<blockquote>
<p>"The zone 'projects/XXXXX/zones/europe-west4-b' does not have enough
resources available to fulfill the request. Try a different zone, or
try again later."</p>
</blockquote>
<p>I thought it might be the quota problem at first, after checking my quota, it showed all good. Actually, I listed the available zones, europe-west4-b was available, but I still gave a shot to move the zone. Then I tried <code>"gcloud compute instances move XXXX --zone europe-west4-b --destination-zone europe-west4-c"</code>, however, it still failed, popped up the error: </p>
<blockquote>
<p>"ERROR: (gcloud.compute.instances.move) Instance cannot be moved while
in state: TERMINATED"</p>
</blockquote>
<p>Okay, terminated... then I tried to restart it by <code>"gcloud compute instances reset XXX"</code>, the error showed in the way:</p>
<blockquote>
<p>ERROR: (gcloud.compute.instances.reset) Could not fetch resource:
- The resource 'projects/XXXXX/zones/europe-west4-b/instances/XXX'
is not ready</p>
</blockquote>
<p>I searched the error, some people solved this problem by deleting the disk. While I don't want to wipe the memory, how could I solve this problem?</p>
<p>BTW, I only have one instance, with one persistent disk attached.</p>

Chart.js creating a line graph using dates : <p>I can't seem to get Chart.js to work with dates. I have tried quite a few different methods:</p>
<pre><code>let examChart = document.getElementById("examChart").getContext("2d");
let examLineChart = new Chart(examChart, {
type: "line",
data: [
{ t: new Date("2015-3-15 13:3"), y: 12 },
{ t: new Date("2015-3-25 13:2"), y: 21 },
{ t: new Date("2015-4-25 14:12"), y: 32 }
],
options: {
label: "placeholder"
}
});
</code></pre>
<p>And:</p>
<pre><code>let examChart = document.getElementById("examChart").getContext("2d");
let examLineChart = new Chart(examChart, {
type: "line",
data: [
{ t: "2015-3-15 13:3", y: 12 },
{ t: "2015-3-25 13:2", y: 21 },
{ t: "2015-4-25 14:12", y: 32 }
],
options: {
label: "placeholder"
}
});
</code></pre>
<p>And:</p>
<pre><code>let examChart = document.getElementById("examChart").getContext("2d");
let examLineChart = new Chart(examChart, {
type: "line",
data: [
{ t: "Sun Mar 15 2015 12:03:45 GMT+0000 (GMT Standard Time)", y: 12 },
{ t: "Wed Mar 25 2015 12:02:15 GMT+0000 (GMT Standard Time)", y: 21 },
{ t: "Sat Apr 25 2015 13:12:30 GMT+0100 (GMT Daylight Time)", y: 32 }
],
options: {
label: "placeholder"
}
});
</code></pre>
<p>To cover just a few of my attempts, I just can't seem to get how to set dates properly even after reading the documentation (<a href="http://www.chartjs.org/docs/latest/axes/cartesian/time.html" rel="noreferrer">http://www.chartjs.org/docs/latest/axes/cartesian/time.html</a>) (they don't actually give an example)</p>
<p>The HTML being used:</p>
<pre><code><div class="container">
<canvas id="examChart"></canvas>
</div>
</code></pre>
<p>I just have no idea, although I imagine this is a rather simple problem, any help would be greatly appreciated.</p>

How does one scrape all the products from a random website? : <p>I tried to get all the products from <a href="https://www.richelieu.com/" rel="noreferrer">this website</a> but somehow I don't think I chose the best method because some of them are missing and I can't figure out why. It's not the first time when I get stuck when it comes to this.</p>
<p>The way I'm doing it now is like this:</p>
<ul>
<li>go to the <a href="https://www.richelieu.com/us/en/index" rel="noreferrer">index page</a> of the website</li>
<li>get all the categories from there (A-Z 0-9)</li>
<li>access each of the above category and recursively go through all the subcategories from there until I reach the products page</li>
<li>when I reach the products page, check if the product has more SKUs. If it has, get the links. Otherwise, that's the only SKU.</li>
</ul>
<p>Now, the below code works but it just doesn't get all the products and I don't see any reasons for why it'd skip some. Maybe the way I approached everything is wrong. </p>
<pre><code>from lxml import html
from random import randint
from string import ascii_uppercase
from time import sleep
from requests import Session
INDEX_PAGE = 'https://www.richelieu.com/us/en/index'
session_ = Session()
def retry(link):
wait = randint(0, 10)
try:
return session_.get(link).text
except Exception as e:
print('Retrying product page in {} seconds because: {}'.format(wait, e))
sleep(wait)
return retry(link)
def get_category_sections():
au = list(ascii_uppercase)
au.remove('Q')
au.remove('Y')
au.append('0-9')
return au
def get_categories():
html_ = retry(INDEX_PAGE)

yield link
for link in page.xpath('//*[@id="ts_resultList"]/div/nav/ul/li[last()]/a/@href'):
if link != '#':
yield from dig_up_products(link)
def check_if_more_products(tree):
more_prods = [
all_prod
for all_prod in tree.xpath("//div[@id='pm2_prodTableForm']//tbody/tr/td[1]//a/@href")
]
if not more_prods:
return False
return more_prods
def main():
for category_link in get_categories():
for product_link in dig_up_products(category_link):
product_page = retry(product_link)
product_tree = html.fromstring(product_page)
more_products = check_if_more_products(product_tree)
if not more_products:
print(product_link)
else:
for sku_product_link in more_products:
print(sku_product_link)
if __name__ == '__main__':
main()
</code></pre>
<hr>
<p>Now, the question might be too generic but I wonder if there's a rule of thumb to follow when someone wants to get all the data (products, in this case) from a website. Could someone please walk me through the whole process of discovering what's the best way to approach a scenario like this?</p>

Whats the benefit of passing a CancellationToken as a parameter to Task.Run? : <p>Obviously I realize it enables me to cancel the task, but this code achieves the same effect without having to pass the token into Task.Run</p>

Proper way of testing ASP.NET Core IMemoryCache : <p>I'm writing a simple test case that tests that my controller calls the cache before calling my service. I'm using xUnit and Moq for the task.</p>
<p>I'm facing an issue because <code>GetOrCreateAsync<T></code> is an extension method, and those can't be mocked by the framework. I relied on internal details to figure out I can mock <code>TryGetValue</code> instead and get away with my test (see <a href="https://github.com/aspnet/Caching/blob/c432e5827e4505c05ac7ad8ef1e3bc6bf784520b/src/Microsoft.Extensions.Caching.Abstractions/MemoryCacheExtensions.cs#L116" rel="noreferrer">https://github.com/aspnet/Caching/blob/c432e5827e4505c05ac7ad8ef1e3bc6bf784520b/src/Microsoft.Extensions.Caching.Abstractions/MemoryCacheExtensions.cs#L116</a>)</p>
<pre><code>[Theory, AutoDataMoq]
public async Task GivenPopulatedCacheDoesntCallService(
Mock<IMemoryCache> cache,
SearchRequestViewModel input,
MyViewModel expected)
{
object expectedOut = expected;
cache
.Setup(s => s.TryGetValue(input.Serialized(), out expectedOut))
.Returns(true);
var sut = new MyController(cache.Object, Mock.Of<ISearchService>());
var actual = await sut.Search(input);
Assert.Same(expected, actual);
}
</code></pre>
<p>I can't sleep with the fact that I'm peeking into the MemoryCache implementation details and it can change at any point.</p>
<p>For reference, this is the SUT code:</p>
<pre><code>public async Task<MyViewModel> Search(SearchRequestViewModel request)
{
return await cache.GetOrCreateAsync(request.Serialized(), (e) => search.FindAsync(request));
}
</code></pre>
<p>Would you recommend testing any differently?</p>

Do you use pure or impure functions in your React components? : <p>So i've been getting a little bit more into functional programming and immutability.</p>
<p>What I often do when writing a react component is a helper function that returns something based on props/state.</p>
<p>Currently I write both Pure and Impure functions even though most of them could be pure.</p>
<p>Examples for both cases:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="true">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>//pure function
const posts = this.props.posts;
const postId = this.props.selectedPostId;
const pureFunc = (postId, posts) => (posts.find(post => post.id === postId);
//impure function
const impureFunc = () => (
this.props.posts.find(
post => post.id === this.props.selectedPostId
)
)</code></pre>
</div>
</div>
</p>
<p>Please, let's refrain from commenting on the overall structure and validity of the code.</p>
<p>The main point of comparison is to pass arguments and operate on those OR pass something from <code>this</code> context which is not like a global state, but it does feel a lot less like functional programming.</p>
<p>What do you prefer and think?</p>

Storing injector instance for use in components : <p>Before RC5 I was using appref injector as a service locator like this:</p>
<p>Startup.ts</p>
<pre><code>bootstrap(...)
.then((appRef: any) => {
ServiceLocator.injector = appRef.injector;
});
</code></pre>
<p>ServiceLocator.ts</p>
<pre><code>export class ServiceLocator {
static injector: Injector;
}
</code></pre>
<p>components:</p>
<pre><code>let myServiceInstance = <MyService>ServiceLocator.injector.get(MyService)
</code></pre>
<p>Now doing the same in bootstrapModule().then() doesn't work because components seems to start to execute before the promise. </p>
<p>Is there a way to store the injector instance before components load?</p>
<p>I don't want to use constructor injection because I'm using the injector in a base component which derived by many components and I rather not inject the injector to all of them.</p>

How to check the object type on runtime in TypeScript? : <p>I'm trying to find a way to pass an object to function in and check it type in a runtime. This is a pseudo code:</p>
<pre><code>func(obj:any){
if(typeof obj === "A"){
// do something
}
else if(typeof obj === "B"{
//do something else
}
}
a:A;
b:B;
func(a);
</code></pre>
<p>But typeof is always return "object" and I could not find a way to get the real type of "a" or "b". The instanceof did not work either and return the same.
Any idea how to do it in a TypeScript?</p>
<p>Thank you for your help!!!</p>

Spring File Upload - 'Required request part is not present' : <p>I am trying to send POST request to my controller but cannot pass any parameter in any type unless I decide to use JSON. My goal is to pass a String and a file to my controller but I keep getting <code>Required request part 'xxx' is not present</code> error.</p>
<pre><code>@RestController
public class ConfigurationController {
@PostMapping(value = "/config")
public ResponseEntity<?> saveEnvironmentConfig(@RequestParam("file") MultipartFile uploadfile){

<p>I cannot have file here. Similarly if I try:</p>
<pre><code>@RestController

public ResponseEntity<?> saveEnvironmentConfig(@RequestParam("name") String name){
return ResponseEntity.ok().body(null);
}
}
</code></pre>
<p>same thing I cannot get name here. </p>
<p>I am sending request via Postman as given in following screenshot:</p>

<p><a href="https://i.stack.imgur.com/DYp6L.png" rel="noreferrer"><img src="https://i.stack.imgur.com/DYp6L.png" alt="Postman Request 2"></a></p>
<p>The only header tag is for Authorization. I do not have any Content-Type header, I tried to add <code>multipart/form-data</code> but did not help.</p>
<p>Only way I could pass String parameter is by adding to URL. So following <code>http://localhost:8080/SearchBox/admin/config?name=test</code> works but this is not what I want. I want String and File parameters in Body part. </p>
<p>I also tested via CURL:</p>
<pre><code>curl -X POST -H "Authorization:Bearer myToken" -H "Content-Type:Multipart/form-data" http://localhost:8080/SearchBox/admin/config --data 'pwd=pwd'
curl -X POST -H "Authorization:Bearer myToken"http://localhost:8080/SearchBox/admin/config --data 'pwd=pwd'
curl -H "Authorization:Bearer myToken" -F file=@"/g123.conf" http://localhost:8080/SearchBox/admin/config

RMI blocks until remote method return even when new thread is executing inside : <p>Scenario: I have a server that distributes summation problem to registered calculators. </p>
<p>The problem is that when server starts calculators remotely, he executes them inorder (wait for each one to return) although the calculation inside calculator should be done in a separate thread (thus it should return immediately).</p>
<p>Moreover, when I try to get type of current executing thread inside the calculator by parsing it to my thread type, I get error... and if I executed <em>wait</em> inside that thread, server thread stops instead. </p>
<p>Here is my code:</p>
<p>method inside server that solves a problem (this method is also called remotely by a client but I don't think this is related to what is happening)</p>
<pre><code>@Override
public void solveProblem(Agent a, IClient client) throws RemoteException {
Runnable thread = new Runnable(){
@Override
public void run()
{
//some variable initialization...
for(int i=0;i<calcs.size();i++)
{
try {
calcs.get(i).delegate(a, chosen);
System.out.println("delegate to "+i+" done");
} catch (RemoteException e) {
e.printStackTrace();
}
}
}
};
}
</code></pre>
<p>calculator: delegate method initialises new thread and start calculation</p>
<pre><code>@Override
public void delegate(Agent a, ICalculator original) throws RemoteException {
receivedCount=0;
thread = new CalculationThread(a, original);
thread.run();
}
</code></pre>
<p>CalculationThread is an inner class within CalculatorImpl Class</p>
<pre><code>class CalculationThread extends Thread{
private Agent a;
private ICalculator original;
public String name = "Calculation Thread";
public CalculationThread(Agent a, ICalculator original) {
this.a=a;
this.original=original;
}
@Override
public String toString()
{
return "Original Calculation Thread";
}
@Override

{
//start calculation
System.out.println("----start new query----");
double result = 0;
for(double n=a.lowerBound;n<=a.upperBound;n++)
{
result += Math.pow(-1, n)/(2*n+1);
}
result = result*4;
System.out.println("Finished with result("+a.lowerBound+","+a.upperBound+"):"+result);
}
}

How to debug a Java maven spring-boot app in vs code? : <p>I was able to debug a simple Java hello world. The first step was to "compile" with <code>javac -g</code>. I looked up how I would acomplish the same with maven and found <a href="http://docs.spring.io/spring-boot/docs/current/maven-plugin/examples/run-debug.html" rel="noreferrer">http://docs.spring.io/spring-boot/docs/current/maven-plugin/examples/run-debug.html</a>, but those instructions are for running the application and wait for a debugger to connect.</p>
<p>I also tried to use <code>target/classes</code> for <code>classpath</code> in <code>launch.json</code>. The debugger complains that it cannot find a file in the root directory <code>/</code>, but it runs. Althought the debugger is running, the application is not responding to HTTP requests.</p>
<p>Is there a <code>mvn</code> command to compile the application with <code>javac -g</code> and produce a <code>.class</code> the debugger is able to run successfully?</p>

Loop to generate and execute commands doesn't work in python : I have following code for my pyspark script. I am trying to generate a query and run it every time with different values of i. The query should select nested json elements and calculate the size (i.e. number of occurrences). I am calculating this to help me with unit testing the final table which i am creating separately with "explode" functionality.
for i in range(1,10) :
onerowDF = spark.sql("SELECT items['responses'][i]['id'] as items_response_id,
items['responses'][i]['name'] as responses_name FROM responses")")
onerowDf.select(size("items_response_id"), size("responses_name")).show()
I am getting error when I run this:
>AnalysisException: u"cannot resolve '`i`' given input columns: [hasMore, items, total]; line 1 pos 74;\n'Project [items#1.id AS items_id#149, items#1.responseTime AS items.responseTime#154, items#1.responses['i][id] AS items_response_id#150, items#1.responses['i][name] AS responses_name#151, items#1.responses['i][type] AS responses_type#152, items#1.responses['i][answers] AS responses_answers#153]\n+- SubqueryAlias responses\n +- Relation[hasMore#0,items#1,total#2L] json\n"
I have knowingly removed some elements from the code above to make it simpler which is why the error lists more element than my code here.
So why can't I replace the value of i in each query and run the 2 statements and get results?

How can I write an if statement with multiple conditions using && and ||? : <p>I am making a tic tac toe board game and I need the user to enter any position between 1 to 9 then type in X or O. Some conditions I need include is that I want to restrict the user to enter any number greater than 9 and do not enter any character either than 'X' or 'O'.

My code is compiling out of order : <p>I'm using g++ on a Mac to compile a homework assignment. Any help is appreciated (also this isn't even the homework part of the homework, just the setup for the problem he asked us to complete). In my main.cpp I have </p>

test_list.add(3);
test_list.add(2);
test_list.remove();

However my output is: </p>

boop!
1
End of test1
3
End of test1
2

<p>I don't really understand why the code is compiling out of order- shouldn't the boop be at the end? I also don't understand how the code in my textbook (which is where I got the add and remove functions)works. I don't see how the remove function is repeating since it has no loop.
Here they are for reference: </p>

Returning from a function once an async operation is done : <p>I am trying to make use an existing class which returns the data in the form of callback. The call is like this-</p>
<pre><code>class Validator{
validate(){
DataProvider.getInstance(new DataListener(){
@Override
void onDataReady(String data){
//Do something with data
}
});
}
return //data when the above call is finished
}
</code></pre>
<p>I want a clean way to return the data which should be returned when the async call is completed. Putting a while loop and checking for data is an obvious but un-clean way. Can I achieve this using RxJava?</p>
<p>Note: It's ok for the validate function to wait if the call takes time</p>

How to Make Jquery Validation fire conditionally in this case? : <p>I am using <strong>jquery Validator Framework</strong> for validating form which consists of input type <strong>text</strong> and <strong>file</strong> elements .</p>
<p>Initially when the page is loaded in <strong>edit</strong> mode (the Form will have all values filled in)</p>
<p>So at that time when clicked on <strong>Submit</strong> button , the Jquery validation for the input type file should be skipped (as it has already a value)
and it must be fired only incase user removes the picture and tries to <strong>submit</strong> the form .</p>

Does a running JVM detect a change to the computer's timezone? : <p>I can't find any specific docs to answer this question. </p>
<p>I wrote some simple test code to work out what actually happens on Java 1.8 on OS X 10.12:</p>
<pre><code>public static void main(String[] _args) throws InterruptedException {
while (true) {
int calendarTimezoneOffset = Calendar.getInstance().get(Calendar.ZONE_OFFSET);
System.out.println("calendarTimezoneOffset = " + calendarTimezoneOffset);
ZoneOffset offset = ZonedDateTime.now().getOffset();
System.out.println("offset = " + offset);
Thread.sleep(1000);
}
}
</code></pre>
<p>Both the old way (Calendar) and the new way (Java 8's Date and Time library) do not detect any change I make to the OS's timezone while the JVM is running. I need to stop and start the code to get the changed timezone.</p>
<p>Is this by design? Is this reliable behaviour across JVM implementations and operating systems?</p>

How to tell SwiftUI views to bind to more than one nested ObservableObject : <p>I have two classes nested in another class, which is an observable object in a SwiftUI view. Even though properties in the nested classes are declared as @Published, their values (when they change) do not update in the main view.</p>
<p>A similar question has been asked here, and I could use it to get it to work for one of the two subclasses, but not both.</p>
<p><a href="https://stackoverflow.com/questions/58406287/how-to-tell-swiftui-views-to-bind-to-nested-observableobjects">How to tell SwiftUI views to bind to nested ObservableObjects</a></p>
<p>This is the model:</p>
<pre><code>class Submodel1: ObservableObject {
@Published var count = 0
}
class Submodel2: ObservableObject {
@Published var count = 0
}
class Model: ObservableObject {
@Published var submodel1: Submodel1 = Submodel1()
@Published var submodel2: Submodel2 = Submodel2()
}
</code></pre>
<p>And this is the main view:</p>
<pre><code>struct ContentView: View {
@ObservedObject var model: Model = Model()
var body: some View {
VStack {
Text("Count: \(model.submodel1.count)")
.onTapGesture {
self.model.submodel1.count += 1
}
Text("Count: \(model.submodel2.count)")
.onTapGesture {
self.model.submodel2.count += 1
}
}
}
}
</code></pre>
<p>Adding this to the model class (see previous Stackoverflow question) works for updating on submodel1 changes, but not both:</p>
<pre><code> var anyCancellable: AnyCancellable? = nil
init() {
anyCancellable = submodel1.objectWillChange.sink { (_) in
self.objectWillChange.send()
}
}
</code></pre>
<p>What I'm looking for is some way to pass on changes of both the submodel1 and submodel2 to my view.</p>

Why is my Model object always null on my Razor Page in dotnet core 2.x Razor Page app? : <p>I'm creating a Partial View as a part of my Index.cshtml.
I am following the basics outlined in the Microsoft article => <a href="https://docs.microsoft.com/en-us/aspnet/core/mvc/views/partial?view=aspnetcore-2.1" rel="noreferrer">https://docs.microsoft.com/en-us/aspnet/core/mvc/views/partial?view=aspnetcore-2.1</a></p>
<p>The summary of it is that I'm :
Adding a span to my Index.cshtml file which is actually loaded with the HTML from a Razor Page.
The relevant HTML in Index.cshtml looks like the following:</p>
<pre><code><span id="basicView">
@{
Model.UserName = "IndexUser";
await Html.RenderPartialAsync("BasicPartial", Model);
}
</span>
</code></pre>
<p>I have added public property to my IndexModel named UserName in the RazorPage and it looks like the following:</p>
<pre><code>namespace FirstCore.Pages
{
public class IndexModel : PageModel
{
public string UserName;
public void OnGet()
{
}
}
}
</code></pre>
<p>It is kept very simple for this example.
So, in the HTML in the Index.cshtml you can see that I set the value of that public property to "IndexUser" and then I pass the name of the Razor Page ("BasicPartial" - View) and the Model object to the BasicaPartial Razor Page.</p>
<p>The BasicPartial page is very simple -- was generated from the Visual Studio 2017 template - Add...Razor Page... The entire things looks like:</p>
<pre><code>@page
@model IndexModel
@*
For more information on enabling MVC for empty projects, visit http://go.microsoft.com/fwlink/?LinkID=397860
*@
<div>This is the text and the user name is @(Model.UserName).</div>
</code></pre>
<p>Actually, the only important part is the and the place where I'm reading the property value of UserName out of the passed in Model.
You can see I've also defined the @model as an IndexModel at the top.</p>
<p><strong>The Main Problem - Model is ALWAYS Null</strong></p>
<p>When I run this very simple example. The application tells me that the Model object is null.</p>
<p><a href="https://i.stack.imgur.com/MPEcm.png" rel="noreferrer"><img src="https://i.stack.imgur.com/MPEcm.png" alt="Model is null"></a></p>
<p>You may believe that it is the UserName that is null, but if I put a very simple directive at the top like </p>
<pre><code><div>@Model</div>
</code></pre>
<p>Then it tells me that Model is null, even though I know I'm passing it in.</p>
<p>Do you know why it is null?</p>

Why doesn't F# Compile Currying into Separate Functions? : <p>So I'm trying to learn F# and as I learn new things I like to look at the IL to see what's happening under the covers. I recently read about Currying, an obvious fundamental of the language. </p>
<p>According to <a href="https://fsharpforfunandprofit.com/posts/currying/">F# for fun and Profit</a> when you create the below function:</p>
<pre><code>let addItems x y = x + y
</code></pre>
<p>What is really happening is there are two single argument functions being created.</p>
<pre><code>let addItems x =
let subFunction y =
x + y
subFunction
</code></pre>
<p>and when you invoke the function with addItems 5 6 the order of operations are as follows</p>
<ol>
<li><p>addItems is called with argument 5</p></li>
<li><p>addItems returns subFunction</p></li>
<li>subFunction is called with argument 6</li>
<li>subFunction has argument 5 in scope so it adds and returns the sum of 5 and 6</li>
</ol>
<p>All of this sounds fine on the surface. However, when you look at the IL for this it tells a different story. </p>
<pre><code>.method public static int32 testCurry(int32 x,
int32 y) cil managed
{
.custom instance void [FSharp.Core]Microsoft.FSharp.Core.CompilationArgumentCountsAttribute::.ctor(int32[]) = ( 01 00 02 00 00 00 01 00 00 00 01 00 00 00 00 00 )
// Code size 5 (0x5)
.maxstack 8
IL_0000: nop
IL_0001: ldarg.0
IL_0002: ldarg.1
IL_0003: add
IL_0004: ret
} // end of method Sandbox::testCurry
</code></pre>
<p>We can clearly see in the IL that a single static function that takes two arguments and returns an Int32 is created. </p>
<p>So my question is, why the discrepancy? This isn't the first time I've seen IL that doesn't jive with the documentation either... </p>

Check multiple buttons with same id with javascript : I'm trying to build a website where people can make a reservation, I'm using a database to collect the times and php to display it. It displays all times within 5 days, including the ones that aren't available. They are displayed as buttons, all sharing the same id. I got stuck at the last step, disabling the buttons with unavailable times. Since the only difference between these buttons is their background color (grey for unavailable and green for available) I figured I'd use a javascript function in which it checks the background colors of the boxes in a condition and then the grey ones get disabled and the green ones give a form. However: it'll only check the color of the first button and all buttons give the same result as that one. My page will always display 50 buttons, so I thought I could just use a while loop with an auto-decrement at the end, however I can't seem to find out how to check the next button, it will now only check the same button again and again. Here's a part of the php-code to show the buttons with the right color (I've take some irrelevant parts out):
while($row = $results->fetch_assoc()){
$color = "##8fd6a5";
if (!empty($row['unavailable'])){
$color = "##9b9393";
}
$time= new DateTime($row['time']);
if ($time->format('H') == '08'){
echo '<button id="myBtn" onload="disablebuttons()" class="buttonstyle"
style="background-color: '.$color.'">'.$time>format('m/d H:i').'</button>';
}
This works entirely, but since all buttons have id="myBtn" when disablebuttons() executes, it only looks at the first button, following this code:
function disablebuttons() {
var amountButton = 50;
while (a > 0){
var buttondisable = document.getElementById("myBtn");
if (buttondisable.style.backgroundColor == "rgb(155, 147, 147)"){
document.getElementById("myBtn").disabled = true;
a--;}
}
}
I've tried to delete the variable at the end of the while loop and place the "var buttondisable = document.getElementById("myBtn");" inside the loop, however this did not work. Can somebody help please?

<p>But If I use this i got the error <code>main.cpp|14|error: expected ';' before 'ia'|</code>. So this isn't working. How can I create these template things, to work? Am I misunderstood, here <code>array_appender</code> don't have work as I think, as I wrote?</p>

how to sum results from an argument,that come in array form : i have this fortran 95 do-loop code which return answers in array form, please how do i find the SUM of the answers (fv) without writing them out,because they're iterative and subject to change. thanks
!.......vapor fraction..............
do i=1,6
FV=Z(I)*(K(i)-1)/(VOLD*(K(i)-1)+1)
write(*,99001)FV
END DO

Redirecting domains to local addresses : <p>Clients are connecting to private servers using OpenVPN, currently using raw IPs (<code>172.X.X.X</code>) but I would like to point more user-friendly subdomains (<code>something.ourdomain.com</code>) to those private IPs</p>
<p>Key is to</p>
<ul>
<li><strong>Not make our private topology public</strong>, so binding subdomains to a public DNS is not an option</li>
<li><strong>Be able to push new settings to all clients efficiently</strong>, so modifying local hosts-files whenever a private IP updates could potentially be cumbersome</li>
<li><strong>Not tie the routing to a specific local hardware</strong>, so doing the routing on say e.g. our office router is not really an option</li>
</ul>
<p>Any suggestions how to achieve this considering the above points? Set-up a private DNS? Do the routing in OpenVPN?</p>

findChessboardCorners IS GIVING GARBAGE VALUE IN CORNERS : Here is my code
#include <opencv/cv.h>
#include <opencv/highgui.h>
#include<opencv2/opencv.hpp>
#include<iostream>
//#include<vector>
using namespace cv;
using namespace std;
int main()
{
VideoCapture cap = VideoCapture(0);
int successes = 0;
int numBoards = 0;
int numCornersHor = 6;
int numCornersVer = 4;
int numSquares = (numCornersHor - 1) * (numCornersVer - 1);
Size board_sz = Size(numCornersHor, numCornersVer);
vector<Point2f> corners;
for (;;)
{
Mat img;
cap >> img;
Mat gray;
cvtColor(img, gray, CV_RGB2GRAY);
if (img.empty()) break; // end of video stream
imshow("this is you, smile! :)", gray);
if (waitKey(1) == 27) break; // stop capturing by pressing ESC
bool found = findChessboardCorners(gray, board_sz, corners, CALIB_CB_ADAPTIVE_THRESH);
if (found == 1)
{
cout << corners.size()<<"\n";
cornerSubPix(gray, corners, Size(11, 11), Size(-1, -1), TermCriteria(CV_TERMCRIT_EPS | CV_TERMCRIT_ITER, 30, 0.1));
drawChessboardCorners(gray, board_sz, corners, found);
}
}
cap.release();
waitKey();
return 0;
}
What code is doing is, if "chessBoard" is found during capturing frames from webcam, it will print the corner size (I did it because I was not getting the output of the tutorial code and I wanted to find where the bug is!)
Here is the image of my output:[1]

Adding an element beneath the root based on condition :
I'm reading an xml file using SAX, then I'm comparing the children of the xml file to validation rules that I got from my database in (validateByRules) Now based on the validation, I'm adding to each chilld, a subchild: <DESC><DESC/> . Now What I want is that after iterating all the children of the document, if at least one validation is wrong, in any of the children. Then an element is added beneath the root of name: <error>. For that I created a counter in VALIDATEbYrULES. Bur from there I'm not positively sure on how to continue. Any help?
public void execute() throws Exception {
try{
Document xmlDoc = convertXmlFileToDocument("c:\\TEST.xml");
String xmlType = xmlDoc.getRootElement().getAttributeValue("type");
HashMap<String, HashMap<String, String>> hashValidationRules = getRulesByType(xmlType);
List<Element> childElem = xmlDoc.getRootElement().getChildren();
Element updatedElem = null;
updatedElem = validateByRules(hashValidationRules, childElem.get(j));
xmlDoc.getRootElement().getChildren().remove(j);
xmlDoc.getRootElement().getChildren().add(j, updatedElem);
}
}
private Element validateByRules(HashMap<String, HashMap<String, String>> hashValidationRules, Element element) {
HashMap<String, String> rules = null;
String desc = "";
String value = "";
int counter = 0;
String fileName = null;
for ( String key : hashValidationRules.keySet() ) {
rules = hashValidationRules.get(key);
if(rules.get("mandatory").equals("true") && (element.getChild(key)==null || element.getChild(key).getValue().equals(""))){
counter ++;
desc = "Mandatory Element ("+key+") does not exist";
}
value = element.getChild(key).getValue();
if(value.length()> Integer.parseInt(rules.get("size"))){
counter ++;
desc = "Field "+key+" exceeded max size ("+rules.get("size")+")";
}
}
element.addContent(new Element("DESC").setText(desc));
System.out.println(counter);
return element;
}
private Document convertXmlFileToDocument(String path){
SAXBuilder sb=new SAXBuilder();
File xmlFile = new File(path);
Document doc = null;
try {
doc = sb.build(xmlFile);
} catch (Exception e) {
e.printStackTrace();
}
return doc;

How to make my enum inherit from a class? : Before:
enum EMagicAbility{
Fireball,
IceBolt,
BlackMagic
};
enum EPhysicalAbility{
SwordLance,
FearlessBlow,
RagnarokRage
};
enum ERangedAbility{
Snipe,
RainOfArrows,
CrossbowShot
};
enum EBiologicalAbility{bla,bla,bla};
enum Eblabla{};
enum Eevenmore{};
... There are many more abilities ...
...
//Each EMagicAbility can only have either zero or one Ability value.
Dictionary<EMagicAbility,Ability> myMagicAbilityDictionary;
//Each EPhysicalAbility can only have either zero or one Ability value.
Dictionary<EPhysicalAbility,Ability> myPhysicalAbilityDictionary;
//Each EPhysicalAbility can only have either zero or one Ability value.
Dictionary<ERangedAbility,Ability> myRangedAbilityDictionary;
//Each EBiologicalAbility can only have either zero or one Ability value.
Dictionary<EBiologicalAbility,Ability> myBiologicalAbilityDictionary;
//Each Eblabla can only have either zero or one Ability value.
Dictionary<Eblabla,Ability> myBlablaAbilityDictionary;
//Each Eevenmore can only have either zero or one Ability value.
Dictionary<Eblabla,Ability> myBlablaAbilityDictionary;
... keeps going on...
...
After:
enum class EAbility{}
enum EMagicAbility:EAbility{
Fireball,
IceBolt,
BlackMagic
};
enum EPhysicalAbility:EAbility{
SwordLance,
FearlessBlow,
RagnarokRage
};
enum ERangedAbility:EAbility{
Snipe,
RainOfArrows,
CrossbowShot
};
enum EBiologicalAbility:EAbility{bla,bla,bla};
enum Eblabla:EAbility{};
enum Eevenmore:EAbility{};
... There are many more abilities ...
...
//Each any enum derived from Eability can only have either zero or one Ability value.
Dictionary<EAbility,Ability> myAbilityDictionary;
//I don't have to create another dictionary when I create a new category of Abilities! Yay!
This is probably a super similar to this question:
http://stackoverflow.com/questions/35191235/what-variable-type-should-i-use-to-store-types-of-a-non-sealed-class-or-interfac/35191505#35191505
In which I would use this instead:
//I can remove all enumerations have such a clean, one-line code <3<3
Dictionary<typeof(Ability),Ability> myAbilityDictionary;
EDIT: After doing some more research, I found out that this may be a viable option for me: http://stackoverflow.com/questions/518442/enum-subset-or-subgroup-in-c-sharp The problem with this is that I will have a behemoth amount of lines of code, which I rather find a more sane way to solve this.
Also, an up vote would be really, really helpful since I can't access some features in stackoverflow, thank you.

Cursor overwrite mode in vscode? : <p>I can't seem to find any way to put the cursor into 'overwrite' mode - as in when you press the insert key and newly typed characters overwrite the existing characters inline. I haven't found any reference anywhere online to the omission or inclusion of such a feature in vscode, but it seems to be a fairly commonly used feature. Does this exist?</p>
