Spock Mock method matching objects with placeholders | <p>I need to test a few interactions with an eventbus. I have wrapped all the arguments in Event classes. The issue is that when I want to verify the events I have to create the event objects in my test and provide all the arguments. I would prefer to only specify the arguments that are important to make clear which arguments are important.</p>
<pre><code>def "initial layout should call page events"() {
given: "register for event"
def listener = Mock(Closure)
eventBus.registerForEvent(PageVisibilityChangedEvent, listener)
when: "viewport twice the size of our pages and can fit 2 pages"
worldport.updateScreenSize(new IntSizeImpl(200, 400))
then: "after the initial layout pages 0 and 1 should have become visible"
1 * listener.call(new PageVisibilityChangedEvent(_, 0, _, Visibility.VISIBLE, _))
1 * listener.call(new PageVisibilityChangedEvent(_, 1, _, Visibility.VISIBLE, _))
0 * _

Spring websocket listen to external queue on client side using SockJs | <p>I have an application that is using spring-websockets and here is the use case</p>
<p>1) User sends a normal HTTP request to the controller(server)</p>
<p>2) The server takes the request and converts it into a message and puts it onto a queue(which has replyTo) and it comes back with request validation successful and I show it on the UI</p>
<p>3) The application that listens to the messages on the queue is a separate application and while it processes the message, it puts the output on another queue in ActiveMQ</p>
<p>4) I am trying to listen to this queue using SockJS on the client side and I do not get any messages.</p>
<p>This is because I am subscribing to the queue in SockJS but I am not actually subscribing as when I look at Active MQ it shows the number of subscribers for that queue is 0.</p>
<p>Can you point me in the right direction as to how to approach this scenario? </p> | 3 |
Polymer: Data binding breaking with on-tap handler on a button within a dom-repeat | <p>Ran into an issue here with Polymer's data binding functionality when used in conjunction with dom-repeat. I'm wondering what I'm missing in order to make this work.</p>
<p>Data binding seems to work fine in some cases with the repeat element, e.g. with input boxes. However, using an on-tap event on a button and editing a field on the associated item object doesn't seem to work for some reason.</p>
<p>Here is my SSCCE (Plunker: <a href="http://plnkr.co/edit/Vof1nYdDFR4Jg4ZXL9DI?p=preview" rel="nofollow">http://plnkr.co/edit/Vof1nYdDFR4Jg4ZXL9DI?p=preview</a>):</p>

the_permalink in loop gives the same results | <p>I need to show an archive list post by post. I created plugin with this code:</p>
<pre><code>function posts_by_year() {

'numberposts' => -1,
'orderby' => 'post_date',
'order' => 'ASC',
'post_type' => 'post',
'post_status' => 'publish'
));
// loop through posts, populating $years arrays
foreach($posts as $post) {
$years[date('Y', strtotime($post->post_date))][] = $post;
}
// reverse sort by year
krsort($years);
return $years;
}
?>
<?php function wyswietl_archiwum (){ ob_start(); ?>
<?php foreach(posts_by_year() as $year => $posts) : ?>
<h2><?php echo $year; ?></h2>
<ul>
<?php foreach($posts as $post) : setup_postdata($post); ?>
<li>
<a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>

<?php endforeach; ?>
</ul>
<?php endforeach; ?>
<?php
return ob_get_clean();
} ?>
<?php add_shortcode( 'archiwum', 'wyswietl_archiwum' );

<p>When I put shortcode <code>[archiwum]</code> on any page, I get the list but every one item displays current page title and links to itself.</p>

Run function base on conditional statement | <p>In my WordPress functions file I have used the code </p>
<pre><code>function banners() {
if ( $GLOBALS['theme_settings']['banners'] == false ) {
wp_enqueue_style('banner', get_template_directory_uri().'/css/banners.css', array(), '1.0.0', 'all');
}
}
add_action('admin_enqueue_scripts', 'banners');
</code></pre>
<p>and this works fine, however, I can't help but think there must be a better way because the add_action will sometimes be running with no file to enqueue. I have tried to put the conditional statement outside of the function but that doesn't seem to work.</p> | 3 |
How can I use a for loop in PHP to return mysql data | <p>I am making an app that will list employees by a certain store in a listview. My current function in my DB_Functions.php file is:</p>
<pre><code>public function getEmployeeList($name) {
$stmt = $this->con->prepare("SELECT employee_name FROM employees WHERE name = ?");
$stmt->bind_param('s', $name);
if ($stmt->execute()) {
$employee_list = $stmt->get_result()->fetch_assoc();
$stmt->close();
if (empty($employee_list)) {
return NULL;
} else {
return $employee_list;
}
}
}
</code></pre>
<p>and in my employees.php file I have the following code:</p>
<pre><code><?php
require_once 'include/DB_Functions.php';
$db = new DB_Functions();
$response = array('error' => FALSE);
if (isset($_POST['name'])) {
$name = $_POST['name'];
$employee_list = $db->getEmployeeList($name);
if ($employee_list != false) {
$response['error'] = FALSE;
//EMPLOYEE LIST OBJECT HERE
} else {
$response['error'] = TRUE;
$response['error_msg'] = 'No employees have been added to this profile.';
echo json_encode($response);
}
} else {
$response['error'] = TRUE;
$response['error_msg'] = 'You have not logged in to your store\'s account, please log in first.';
echo json_encode($response);
}
?>
</code></pre>
<p>I would like to have an employee_list object in the commented space above. Something like:</p>
<pre><code>$response['employee_list']['0'] = $employee_list['0'];
$response['employee_list']['1'] = $employee_list['1'];
$response['employee_list']['2'] = $employee_list['2'];
</code></pre>
<p>etc... etc...</p>
<p>After that JSONObject is returned to the android app, the contents will be listed in a listview. I would need a for loop (<em>I think</em>) because the employee number will never be known since each store will be able to add and remove employees as they wish. Can someone point me in the right direction and also advise if I am using the correct approach as far as the rest of the code. Thanks.</p> | 3 |

ES6 play nice.. How to use this.someFunction() inside angular directive without controllerAs? | <p>Take for example this Angular directive that works fine in Chrome & Firefox:</p>
<pre><code>// using Angular v1.4.8
myApp.directive('myDir', function(){
return {
restrict: 'E',
templateUrl: 'directive/myDir/myDir.html',
bindToController: true,
controllerAs: 'mydir',
controller: function($scope){
var thisdir = this;
// Using ES6 arrow functions
thisdir.shoutOut = () => {
console.log("Shouting out!");
}
}
}
});
</code></pre>
<p>Now on IE11 it throws a syntax arrow because the browser does not recognize arrow functions. However, I can still use:</p>
<pre><code>function shoutOut(){
console.log("Shouting out!");
}
</code></pre>
<p>But I want to be able to use <code>var thisdir = this</code> throughout my directives. For cleaniness of code, I also want to avoid using <code>$scope</code> in my directives. Ultimately my directives will depend on eachother in order to create a larger directive/component, which is why i would like to use <code>var thisdir = this</code>.</p>
<p>So how can I achieve this while maintaining syntax compatibility with older browsers? If you see a cleaner way to go about this, please let me know!</p> | 3 |
GUI for plotting data from 3D cell matricies in Matlab | <p>I have a matlab cell matrix in which each cell contains a vector of numbers. I am trying to visualize the cell matrix data and plot various rows with various columns. However, I am still not sure which rows/columns should I pick and whether I should take the average, max or first/second/third.. value from each cell to get the desired output I am looking for.
As I continuously change my plotting parameters, it gets really annoying to change multiple loops and their limits every time I want to try another plot. Trying to extract the correct information you want from a such a jungle becomes really frustrating.</p>
<p><img src="https://i.stack.imgur.com/uWSKU.png" alt="Screenshot of the cell matrix"></p>
<p>I am looking for a software/toolbox/GUI to help me play around and visualize this 3D cell matrix so I can plot whatever I need by some simple clicks and avoid the confusion of several loops inside each other.</p>
<p>Would there be any idea to help me through that?</p> | 3 |
How does LayoutInflater deals with IDs when there are multiple copies of an .xml file? | <p>To make my point easier to explain, I will use an example:</p>
<pre><code><EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/thisIdIsVeryCool"/>
</code></pre>
<p>this is the .xml that I want to inflate and I will call it sublayout.xml</p>
<p>Now imagine that I inflate sublayout.xml in the main_layout.xml three times.</p>
<p>It does not give any error so I run the app on my device.
Now, right in front of my eyes, there are 3 EditText, all of wich with <code>thisIdIsVeryCool</code> as id.
this makes no sense to me...</p>
<p>What if i want to check if <code>thisIdIsVeryCool</code> is empty or not, and 2 of these EditText are indeed empty, but one of them is not?</p>
<p>Ok, it seems like i haven't ever tried to actually write a code like that and i'm lazy, but trust me, i've tried.
Actually, i've tryed a slightly different thing, and it seems that, when in the .java I refer to <code>thisIdIsVeryCool</code>, it affects only the inflated sublayout.xml that was created first.</p>
<p>so... how are called the others EditText?</p>

ControlTemplate working correctly in Blend but not in actual application | <p>I created a custom button, nothing too fancy, just an extension of the mahApps SquareButton with a little colored marker at the left side.</p>
<p><a href="https://i.stack.imgur.com/4oa3d.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/4oa3d.png" alt="enter image description here"></a></p>
<p>I designed it in Blend, and copied the code into my real application in Visual Studio. When starting in Blend it's working just fine, when starting in Visual Studio the marker is not visible and also the Text gets left aligned, the button is looking nearly like a normal SquareButton. What am I doing wrong?</p>

...
</Style>
<Style TargetType="{x:Type view:MarkerButton}" BasedOn="{StaticResource MarkerButtonStyle}"/>
</ResourceDictionary>
</code></pre>
<p>Then I used the button like this:</p>
<pre><code><view:MarkerButton MarkerColor="{Binding Color}" Content="{Binding Name}" MarkerWidth="15" .... />
</code></pre>
<hr>
<p>With Punker76's solution of extending the button I get this:</p>
<p><a href="https://i.stack.imgur.com/QEAI5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QEAI5.png" alt="enter image description here"></a></p>
<p>The positioning is broken, but the xaml seems to be right....</p>
<hr>
<p>Fixed my old solution, the problem was my width: I declared it as uint instead of double. Still, the button appears different to the normal square style (different border, focus rect, text alignment) and I don't know why.</p>

jQuery animate and size settings works only in Chrome | <p>I am trying to get a slider to work on all browsers, but it only works on Chrome.
I wrote it once, then I rewrote it thinking I did some mistake. But it seems that I fail find what causes my code not to work in any browser except Chrome.
Also the responsiveness of how many thumbnails it should show is only working on Chrome.
My best guess is that it's because I am not using selectors right.</p>
<p>I only wrote the code for the right arrow, and stopped at that because I was trying to find out what causes the animation not to work and also the calculations which determine margins and maximum slides.</p>

Java EE Clarification on Workflow for JSP and Servlets | <p>I am attempting to learn Java EE. After struggling through trying to understand the Java stack, it appears that that a basic dynamic web application can be accomplished by focusing on JSP and Servlets so I want to start there.</p>
<p>In Net Beans I have a basic project set up with a tomcat server and when I hit run I can get the web page to generate and display the default index.jsp page. I have added a css file to the project and this jsp page looks like any standard html page now. I then create a new servlet. I was also able to create a link in the index.jsp page so when I click on it, it calls the servlet.</p>
<p>What I don't understand is why when I create the servlet in Net Beans, the processRequest method comes pre-populated with several html print statements. I could easily make this page look like the jsp page I started with, making me wonder why I even need a JSP page. It appears the entire application could be comprised of servlets.</p>
<p>Could someone please explain the proper interaction between the two? It appears the index page can contain links that call various servlets, perhaps to access a database of comments, then do I create the response table in the servlet, or would I pass that information to another JSP page?</p>
<p>Understanding these basic workflows would really help. Thanks</p> | 3 |
Swashbuckle Complex Objects | <p>Given an object parameter such as:</p>

public List<ABC> listABC { get; set; }
}
public class ABC {
public string A { get; set; }
public string B { get; set; }
public string C { get; set; }
}
</code></pre>
<p>I know it is possible to get Swashbuckle to show XYZ.listABC in the UI and then to enter the list in the text box if you use [FromUri(Name="XYZ")] before the parameter. </p>
<p>Is there a way to expose the list object ABC in the UI instead of having a generic text box for XYZ.listABC?</p> | 3 |

<p>Even uglified and compressed the file size is 730 kb which is huge for the little code i have written.</p>
<p>I noticed that if a take out EG:</p>
<pre><code>var NuevoPedido = require('./components/Pages/NuevoPedido.jsx');
Which is a "page wrapper"
</code></pre>
<p>and it's corresponding route</p>
<pre><code><Route path="/pedido/nuevo" component={NuevoPedido} />
</code></pre>
<p>Removing any route and it's component cut's down like 500 kb from the 1.5 mb file, but that's crazy because those components are not any near to be 500kb, so i suspect that there has to be some kind of dependencies duplication, i tried npm dedupe with no luck.</p>

How to animate multiple points (planets) using gnuplot, from a single data file. | <p>I'm trying to make an animation of Jupiter, the sun and an asteroid at the stable Lagrange point L5 as they orbit around their center of mass. I want to do this animation using gnuplot.</p>
<p>I have written a programme which finds their positions at time t/AU. The data I get is below, has columns, time, x position, y position, and has rows, planet, sun, asteroid. I have looked at other solutions to animating in gnuplot but they do not seem to work for me. Please help me understand what I need to type into the gnuplot command line to get an animation of this data please.</p>
<p>Thank you.</p>

Calling external script from Flink | <p>This might seem like a very complex problem to some of you. I want to use Apache Flink to apply some algorithms on data from a SocketStream. However, these algorithms are external executables that I am running using Scala's <code>sys.process</code> package. Here is what I want Flink to do:</p>
<ol>
<li><p>Get individual lines from SocketStream:</p>
<p><code>val text = env.socketTextStream(hostName, port)
val lines = text.flatMap { _.toLowerCase.split("\\n") filter { _.nonEmpty } }</code></p></li>
<li><p>Call my executable algorithm with these lines as command line parameters. Somewhat like this:</p>
<p><code>var op = "./Somefile.py "+lines!</code></p></li>
<li><p>Print the output I get from the executable.</p>
<p><code>op.print()</code></p></li>
</ol>
<p>Obviously this is not the correct way to do what I am trying to do as <code>op</code> unlike <code>lines</code> is not a data sink and thus nothing is getting printed. Is there some way I can achieve this?</p> | 3 |
"Re-opening" DocuSign "Delivered" envelope in embedded view | <p>My question in a nutshell: Using the SOAP API, is there a way to allow the signer to "Re-open" an envelope that is in Delivered Status (Not expired or completed) in an embedded application?</p>
<p>The details: Using the SalesForce SOAP API examples given here <a href="https://github.com/docusign/docusign-soap-sdk" rel="nofollow">https://github.com/docusign/docusign-soap-sdk</a> (thank you to whoever provided these!), I am having great success creating NEW envelopes. However, using the methods provided in the samples, a brand new envelope is created without regard for existing envelopes. I would like to see if there are any unexpired, delivered envelopes and present that before creating a new one. Unfortunately, I'm not seeing any way to fetch an envelope using an Envelope ID (eg: C87908AD-908E-45F6-B4F9-8B6A514XXXXX) and present that to the signer.</p> | 3 |

Google Analytics API calculate internal referrals. | <p>I can find out the traffic sources for a page with a given permalink from the Google Analytics API that return a result like this:</p>
<pre><code>Array(
[direct] => 1
[social] => 0
[3rdparty] => 0
[search] => 0
)
</code></pre>
<p>using a query call like this:</p>
<pre><code>public static function get_traffic_sources( $args ) {
global $post;
$default = array(
'per_days' => 30 ,
'skip' => 0,
'query' => 'traffic_sources',
'path' => Inbound_Google_Connect::get_relative_permalink( $post->ID )
);
$request = array_replace( $default , $args );
return Inbound_Google_Connect::load_data( $request );
}
</code></pre>
<p>But I would like to find out the number of internal referrals. Google does not seem to include this in their traffic_sources query. Any leads on how I could get this extra bit of information?</p> | 3 |
Array data split | <p>I don't know if i am doing the array add by a correct method.</p>
<pre><code>for (var i=0; i < result.length; i++){

var b = Array();
a.push(result[i].data.mentionTotal);
b.push(result[i].profileName);
mentionArr.push(b+a);
}
</code></pre>
<p>The for loop above gave a result like this :</p>
<pre><code>[["orange1494"],["ansontest231403"],["happyboy0"],["babygirl0"]]
</code></pre>
<p>But i want to split the data so i tried to do:</p>
<pre><code>mentionArr.push(b+'","'+a);
</code></pre>
<p>In order to split it but the outcome is like :</p>
<pre><code>["orange\",\"1494","ansontest23\",\"1403","happyboy\",\"0","babygirl\",\"0"]

how is the subclass property "quantity" initialised | <p>I'm trying to learn the concept of inheritance and initialisation in swift and have came up with the following code. "the swift programming language 2.1" states that if a subclass provides implementation of all of its superclass's designated initialiser, the subclass also automatically inherits all of its superclass convenience initialisers too. </p>
<p>Therefore the subclass "<code>RecipeIngredient</code>" should have inherited superclass "<code>Food</code>"'s <code>convenience init(){ self.init(name: "[unnamed]")</code>. But this particular convenience init only initialise the var <code>name</code>, how can it initialise the subclass property <code>quantity</code>? Could someone please explain it to me, how is the subclass property <code>quantity</code> initialised when I create an instance of subclass using the superclass <code>convenience init(){ self.init(name: "[unnamed]")</code>? Thanks in advance for any help!</p>
<pre><code>class Food {
var name: String
init(name: String){
self.name = name
}
convenience init() {
self.init(name: "[unnamed]")
}
}
class RecipeIngredient: Food{
var quantity: Int
init(name: String, quantity: Int){
self.quantity = quantity
super.init(name: name)
}
override convenience init(name: String){
self.init(name: name, quantity: 1)
}
}
let ingredientOne = RecipeIngredient()
ingredientOne.name
ingredientOne.quantity

<li>first the arrow don't look like part of the slider menu which is separate from all the other components.</li>

<li>When I open the slider menu, the upper menu's height get extended with no reason.</li>

Update application layout icon | <p>In my application controller I have a method which I use to set notifications and the notifications icon on the application layout menu. I run this method with before_action:</p>
<pre><code>def set_notifications
if user_signed_in?
@notifications = Notification.where(user_id: current_user.id)
@notifications.each do |n|
if n.read == false
return @icon_path = 'notification-alert-icon'
end
end
@icon_path = 'notification-icon'
end
end
</code></pre>
<p>This works fine as I get the correct notification icon when I have unread notifications:</p>
<pre><code><li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false"><%= image_tag(@icon_path) %></a>
<ul class="dropdown-menu">
<% if @notifications == 0 %>
<li class="text-center" style="color:white;">Você ainda não tem notificações</li>
<% else %>
<% @notifications.each do |n| %>
<li><%= link_to n.question.title, question_path(n.question), class: 'text-center' %></li>
<% end %>
<% end %>
<li role="separator" class="divider"></li>
<li><%= link_to 'Ver todas as notificações', "#" %></li>
</ul>
</li>
</code></pre>
<p>When the user clicks the notification icon, then clicks the question he was notified on, the questions_controller marks that notification as read (inside the show action):</p>
<pre><code>notifications = Notification.where(question_id: question.id) if Notification.exists?(question_id: question.id)
if notifications
notifications.each do |notification|
if notification.user_id == current_user.id
notification.read = true
notification.save
end
end
end
</code></pre>
<p>What I haven't been able to do is: how do I update the @notifications object and the notification icon on the application layout after marking the notification as read? I know I can call the method set_notifications but that alone won't reload application layout and change the icon right?</p> | 3 |
Update Google Play services for an old app | <p>I have an old app which uses Google play services 5.08. Since the app uses kiosk mode, we never updated google play services on the device. Now I have to update the google play services to 8.4. I also want the already existing users to use the app without getting crashes. So how do I support both of 5.08 and 8.4 APIs to support in the app? I see Google doesn't expose the APIs of 5.08 when I use 8.4 in Gradle file. </p> | 3 |

Bash history command, store whole term ignoring any options | <p>I have a script which repeatedly waits for user entered text and then calls another script with the entered text. <a href="https://stackoverflow.com/a/6794304/2102457">SO code credit, 'version 1'.</a></p>
<pre class="lang-bash prettyprint-override"><code>while IFS="" read -r -e -p 'Enter search term: ' -a search_term; do
if [ "$search_term" != "" ]; then
/path/to/script ${search_term[@]}
else
echo "Bye."
exit 0
fi
history -s ${search_term[@]}
done
</code></pre>
<p>It calls the Bash builtin <code>history</code> command to allow scrolling up to previous entries.</p>
<p>The problem is when <code>search_term</code> begins with an option, e.g. <code>-x exclude_this search term</code>. This results in the following error: <code>history: -x: invalid option</code>. How do I force the <code>history</code> command to add the whole of <code>search_term</code> as a history entry and not to process any options that <code>search_term</code> may begin with? i.e. The whole of <code>-x exclude_this search term</code> should be added as a history entry.</p>
<p>Note: This can actually be solved by adding an initial empty string like this <code>history -s "" ${search_term[@]}</code> but each history entry is then prefixed by a space and repeated use adds a space each time pushing the entries further and further right. So this is a rather inelegant solution.</p>
<p>Thanks.</p> | 3 |

PowerShell Set-AuthenticodeSignature - IncludeChain Options Advantages/Disadvantages? | <p>When using <code>Set-AuthenticodeSignature</code>, there is an option called <code>IncludeChain</code>. While there is documentation about what each of the options are, I haven't been able to uncover much guidance surrounding the advantages/disadvantages of each setting (when you would pick one setting over another). </p>
<p>Everywhere I see <code>IncludeChain</code> in examples, it is always set to <code>All</code>. I think <code>All</code> is likely the best answer, but I'd like to understand the benefits and disadvantages of each of the settings. </p>
<ul>
<li><code>Signer</code> </li>
<li><code>NotRoot</code> (default) </li>
<li><code>All</code></li>
</ul>
<p>Other than <code>All</code> making the file quite a bit bigger, what are the specific advantages and disadvantages of each of the settings?</p>

javascript adds body_0$ to ID selector | <p>I am doing a form validation using and the javascript works with just input fields but not Textboxes. I use:</p>
<pre><code> var _firstname;
var box;
try {
box = $("#firstname");
alert("You must enter a first name");
box.focus();
return false;
}catch{
}
</code></pre>
<p>with a front end of :</p>
<pre><code> <div>First Name <span class="required">*</span></div>
<asp:TextBox ID="firstname" name="firstname" runat="server" />
</code></pre>
<p>When I debug the code, it adds a body_0$ to the front of the ID (ie: body_0$firstname), so I'm guessing that's why its always popping up with the "You must enter a first name" alert. Is there a work around?</p> | 3 |
How to modify a two dimensional array passed to a function? | <p>My function is as following</p>
<pre><code>func helper(root: TreeNode?, _ result: [[Int]], _ list: [Int], _ sum: Int, _ total: Int) {
list.append(root!.val)
if(total + root!.val == sum && root?.left == nil && root?.right == nil) {
result.append(list)
}
if(root?.left != nil && sum < total + root!.val) {
helper(root!.left, result, list, sum, total + root!.val)
}
if (root?.right != nil && sum < total + root!.val) {
helper(root!.right, result, list, sum, total + root!.val)
}
}
</code></pre>
<p>When I tried to modify <code>list</code> and <code>result</code> it gave me errors
. I've searched that <code>input</code> keyword can be used to pass parameters by reference, then it can be modified locally as well as externally, but I couldn't make the syntax correct. How can I make it work? Or there is any better way I can modify them?</p> | 3 |
Drag and drop players in a results table inside form to send to PHP (using DragulaJS) | <p>I'm developing the front-end of an app to track tournaments. In one page, the user needs to update the tournament result by dragging a player from a list on the left inside the final results table on the right, that I'll send to a PHP backend for processing (I'm not developing the backend, just need to send the correct data via POST). My requirements are:</p>
<ol>
<li>Have a list of players</li>
<li>Have a results table with fixed positions in each row (one row for 1st, one row for 2nd).</li>
<li>Each position will have 4 related inputs, all named <code>position-1-NAME</code>, in the same row, but different columns</li>
<li>The user should be able to drag players into each position</li>
<li>One player can only be in one position, and each position can only have one player</li>
<li>When a player is placed in the table, he should be removed from the list</li>
</ol>
<p>I've tried several approaches but the one that came close is using the <a href="https://github.com/bevacqua/dragula" rel="nofollow">Dragula JS</a> plugin.</p>
<p>Then, I create the list of players with an <code>ul</code> with the <code>id</code> to make it a container in Dragula:</p>
<pre><code> <ul id="players-container">
<li>
Player 1
</li>
</ul>
</code></pre>
<p>Then, I have a <code>table</code> inside a <code>form</code> tag, and the name of the fields are all named according to the position, like <code>position-1-name-of-the-input</code>:</p>
<pre><code><form method="POST" action="file_to_process_form.php">
<thead>
<th>Position</th>
<th>Player</th>
...
</thead>
<tbody>
<tr>
<td>
1st Position
</td>
<td class="target">
<input type="text" name="position-1-player-name" value="" hidden>
</td>
<td>
...other inputs
</td>
</tr>
</tbody>
</code></pre>
<p>Then, in JavaScript, I made a hack to grab the <code>text()</code> from the <code>li</code> being dragged and put it inside the <code>value</code> attribute of the <code>input</code> of the <code>table</code>, so that I can send the name of the player in the first position to the backend. The code:</p>
<pre><code>dragula([document.querySelector('#players-container'), document.querySelector('.target')], {
isContainer: function(el){
return el.classList.contains('target');
},
revertOnSpill: true
}).on('drop', function(el, target, source, sibling){
elValue = $(el).text();
$(target).find('input').attr('value', elValue);
});
</code></pre>
<p>So far, this is working with some bugs:</p>
<ol>
<li><p>I can drop two players in the same <code>td</code>, and they will show both dragged <code>li</code> in the UI, but the form will only have the value of the last dropped player.</p></li>
<li><p>If I drag the player into all positions, one after another, all inputs will have the value of his name until I drag another player into that position.</p></li>
</ol>
<p>So, I want to accomplish a couple of things:</p>
<ol>
<li><p>Allow only one player inside each <code>td class="target"</code>. I've tried to disable the <code>td</code> by removing the <code>.target</code> class but then I can't move the player again after being dropped.</p></li>
<li><p>Remove the value of the input when I drag the player out.</p></li>
</ol>
<p>I know this is a bit of a hack but I don't have a lot of experience with JS/jQuery and this is the only solution that remotely works so far.</p>
<p>My questions:</p>
<ol>
<li><p>How can I prevent multiple players form being dragged to the same <code>td</code> with Dragula or JS / jQuery code?</p></li>
<li><p>[SOLVED -- see edit] How can I remove the <code>value</code> of the <code>input</code> when I drag a player OUT of the <code>td</code>?</p></li>
<li><p>Do you know a better way to implement these requirements to recommend?</p></li>
</ol>
<p><strong>EDIT</strong></p>
<p>I've managed to solve the question 2 by adding the following code:</p>
<pre><code>dragulaObject.on('drag', function(el, source) {
$(source).find('input').attr('value', '');
});

issue with a variable in javascript | <p>I'm stuck on this little metronome project. It's supposed to flash back and forth between two background colors. It works fine as long as both colors are defined (switch "col" in JS line 12 to any color and it works). However, I'm also trying to make it so I can randomize one of the colors onclick. I can tell (console.log) that my number randomizer is producing a correct hex color value for my variable "col" but I can't get that variable to work. I have tried "col" without quotes.</p>

Remove pattern in first occurence from right to left in file name in bash | <p>Say I have a string file name <code>aa.bb.cc.xx.txt</code>
I would like to remove the first content between . and . (remove .xx) before the .txt to have <code>aa.bb.cc.txt</code>. </p>
<p>I don't want to use rev, cut and rev because this uses 3 commands</p>
<pre><code>echo 'aa.bb.cc.xx.rpm' |rev | cut -d '.' --complement -s -f 2 |rev

<p>Is there any better solution by using bash?

Listen for new urls of ads posted to site | <pre><code>for (var i = 3848450; i > 3848400; i--) {

var datasplit = datastring.toString().split('Sign');
$('#inner-content').append(datasplit[0]);
});
}
</code></pre>
<p>I want to listen for new URLs of ads that are posted without writing some kind of arbitrary code that takes up a lot of memory looping through new URLs, etc. I can do that but it seems redundant and such as my code listed above. Im using noodle.js to get the info from the pages. Now I would like a way to listen for new urls instead of looping through every possible url from a to z. Since I don't know z it's a safe bet I'll be using an if statement but how would one go about incorporating this nth URL without ending up with undefined iterations. Im still learning and find this place has many helpful people. This is simply a fun project I'm doing to learn something new.</p> | 3 |
Android Keyboard - not reachable in cordova app | <p>I am writing a kiosk application for a rooted Android 4.4 tablet. For this I am using <strong>cordova</strong>. This application can only be controlled with a bluetooth remote control. Unfortunetely there is no Touch, Mouse or Keyboard available.</p>
<p>Using the app with the remote control basically is no problem, but unfortunately it is impossible for the user to fill out <code><input></code> -fields!</p>
<p>If the user navigates to an input field, the android-software-keyboard successfully shows up, but it never gets the focus of the remote control. No matter what you press or what you try - you cannot reach it with the remote control. (See attached screenshot)</p>
<p>I have found a <a href="https://github.com/driftyco/ionic-plugin-keyboard" rel="nofollow noreferrer">cordova plugin</a>, but this is mainly for issues when the software-keyboard doesn't show up at all. It doesn't help in my case.</p>
<p><strong>How can I fix this?
How can I focus the keyboard in Java or JavaScript?</strong></p>

Multi-provision, multi-vm Vagrantfile vm filtering | <p>When provisioning for EC2, I only want the 'app' vm. When provisioning locally, I want 'app' and 'pg'. I'm having trouble writing a single Vagrantfile that can cater to both scenarios.</p>
<p>I'd like to invoke this by just using a provider as a way to make it work:</p>
<pre><code>vagrant up --provider=aws
</code></pre>
<p>vs</p>
<pre><code>vagrant up --provider=virtualbox
</code></pre>
<p>AWS would spawn just app. Virtualbox would spawn app and pg.</p>
<p>I'm using vagrant 1.7.2</p>
<p>I have something like the following Vagrantfile:</p>
<pre><code>...
Vagrant.configure(2) do |config|
...
config.vm.define "app" do |app|
# setup app here
...
config.vm.provider :virtualbox do |vbox, override|
# setup virtualbox for app vm here
...
end
...
config.vm.provider :aws do |aws, override|
# setup aws for app vm here
...
end
end
...
config.vm.define "pg" do |pg|
# setup postgres here
...
end
...
end
</code></pre>

JavaFX DataBinding behaves strange | <p>I have a Worker that fills a result list. A ListView is bound to this result list and gets filled with partial results as soon as they are available. Works great!</p>
<p>Then there is a button that works with items in the list. So it should be disabled as long the list is empty. This works for every other list. But not for this one.</p>
<p>I have reduced the sample by stripping the UI components and just using properties. The result is the same. Either there is some kind of bug or I do not understand how the binding works.</p>
<p>I hope for any helping comments on this.</p>
<p>Just put this code into a main() method and you should see the problem. I am using Java 1.8 Update 74.</p>
<pre><code>// a list of items, e.g. in a list view
ReadOnlyObjectWrapper<ObservableList<String>> items = new ReadOnlyObjectWrapper<>(
FXCollections.observableArrayList(new ArrayList<>()));
// a button that is disabled if there are no items
BooleanProperty disabled = new SimpleBooleanProperty();
disabled.bind(Bindings.createBooleanBinding(() -> Boolean.valueOf(items.get().isEmpty()), items));
// a list with results, e.g. from a worker
ReadOnlyObjectWrapper<ObservableList<String>> results = new ReadOnlyObjectWrapper<>(
FXCollections.observableArrayList(new ArrayList<>()));
// the items are bound to the results (the list is showing partial result then)
items.bind(results);
// the button is still disabled
System.out.println(disabled.get()); // expected true !WORKS!
// add a result (should inform the items and the button)
results.get().add("Hello");
// both list should be identical now
System.out.println(results.get()); // expected [Hello] !WORKS!
System.out.println(items.get()); // expected [Hello] !WORKS!
// the button should not be disabled anymore
System.out.println(disabled.get()); // expected false !FALIED!
// try to re-bind the button
disabled.unbind();
disabled.bind(Bindings.createBooleanBinding(() -> Boolean.valueOf(items.get().isEmpty()), items));
System.out.println(disabled.get()); // expected false !WORKS!

No animations/selections in Tabhost | <p>I am trying to implement a tabview with the nice gradual change from one view to another animation and have the current tab highlighted. At current all I can get is the basic tabview that functions, but does instant switching of tabs and no highlighting of selections. Here is my current code:</p>
<pre><code>package com.example.ex.test;
public class MainActivity extends navBar {
private FragmentTabHost mTabHost;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
mTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost);
mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent);
mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("Tab1"),
smithingTable.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab2").setIndicator("Tab2"),
smithingTable2.class, null);
mTabHost.addTab(mTabHost.newTabSpec("tab3").setIndicator("Tab3"),
Map.class, null);
}
}

Bootstrap push/pull questions | <p>I am kind of new to the responsive design and i have some issues working with push pull in bootstrap.</p>
<p>First question is it correct to write rows like that?</p>
<pre><code><div class="row">
<div class="col-xs-12 col-md-6">
<h1>Projects:</h1>
</div>
<div class="col-xs-12 col-md-6">

<textarea class="form-control preventEdit" rows="5" style="min-width: 100%" disabled>DES</textarea>
</div>
</div>
</code></pre>
<p>so at this moment I have something that looks like this at extra small and small devices:</p>
<p>|TEXT1|</p>
<p>|BOX1|</p>
<p>|TEXT2|</p>
<p>|BOX2|</p>
<p>But I need to make the layout look like this at medium and bigger</p>
<p>|TEXT1||TEXT2|</p>
<p>|BOX1 ||BOX2 |</p>
<p>Tried doing it with push and pull but the result is nothing like I wanted. The boxes just flies away.</p>
<p>the code I tried:</p>
<pre><code><div class="row">
<div class="col-xs-12 col-md-6">
<h1>Projects:</h1>
</div>
<div class="col-xs-12 col-md-6 col-md-push-6 ">
<textarea class="form-control preventEdit" rows="5" style="min-width: 100%" disabled>PRO</textarea>
</div>
<div class="col-xs-12 col-md-6 col-md-pull-6">
<h1>Description:</h1>

<div class="col-xs-12 col-md-6">
<textarea class="form-control preventEdit" rows="5" style="min-width: 100%" disabled>DES</textarea>

How to get the timer scheduled tasks done in EJB | <h3>Features I am trying to achieve:</h3>
<ol>
<li>Schedule newsletters to send to customers</li>
<li>I have a JSF page that allows user to trigger the schedule. Once a new schedule is triggered, this schedule information will be added to the progress section in the same page. The progress section is a table, of which each row represents a schedule. Each schedule shows how many emails have already been sent. Upon clicking "refresh" button, the progress table is refreshed to show the current status.</li>
</ol>
<h3>Relavent technologies used</h3>
<ul>
<li>JSF</li>
<li>EJB</li>
</ul>
<h3>Question</h3>
<p>I have already scheduled the emails but <strong>I do not know how to retrieve the status on the JSF page</strong>.</p>
<p>My session bean looks something like this:</p>
<pre><code>@Stateless
public class DefaultEmailScheduleService implements EmailScheduleService {
Queue<String> emailAddresses;
@Resource
TimerService timerService;
@EJB
EmailService emailService;
@PostConstruct
private void postConst() {
}
@Override
public void scheduleEmails(ScheduleExpression se, Collection<String> emailAddresses) {
//set timer
this.emailAddresses = new ConcurrentLinkedQueue<>(emailAddresses);
TimerConfig timerConfig = new TimerConfig();
timerConfig.setPersistent(false);
Timer timer = timerService.createCalendarTimer(se, timerConfig);
//TODO update newsletter/email history
}
@Timeout
public void send(Timer timer) {
if(!emailAddresses.isEmpty()){
Newsletter newsletter = new Newsletter();
newsletter.setTo(emailAddresses.poll());
newsletter.setSubject("Testing");
newsletter.setContent("This is testing newsletter");
emailService.send(newsletter);
System.out.println(newsletter.getFrom() + " --- sent");
}
else {
System.out.println("no more emails");
timer.cancel();
}
}
}
</code></pre>
<h3>My solution</h3>
<p>The somewhat hacking solution I've found so far, which I think would work is that, every time an <code>Newsletter</code> object polled from the queue is sent, I save this <code>Newsletter</code> object to an application scoped bean(like a singleton) so that the newsletters sent can be retrieved by JSF page. When the queue is empty, I clean up the Application bean and update the database. However, I felt like this approach is a smell for some reason.</p>
<p>Any help is greatly appreciated.</p> | 3 |

How can i save this into a variable so that i can save it to a file | <p>I have a bit of code which prints what I want to save but I cant save it as a variable because of the format. Please can you show me how to save this as a variable so that I can save it into a file </p>
<p>It wont let me add a picture but this is what I want to add to a variable (What its printing)</p>

C++ Compile code for all variants of finite number of settings | <p>For example, there is hard logic inside function <code>void Func(long param1, long param2, long param3, long param4, long param5)</code>.</p>
<p>It has a lot of statements inside depends on parameters, different checks, calculations depends on combinations and etc.</p>
<p>And that function is called many million times and takes serious amount of execution time. And I'd like to reduce that time.</p>
<p>All parameters are taken from <code>config.ini</code> file, so, they are unknown at compile time.</p>
<p>But I know, that param1 may be in diapason [1..3], param2 in diapason [0..1] and etc.</p>
<p>So, finally, there is maybe 200 combinations of those parameters.</p>
<p>And I'd like my compiler compile separated 200 combination, and at the beginning of run-time, when <code>config.ini</code> loaded, just choose one of them, and avoid run-time calculation of parameter's dependencies.</p>
<p>Is that possible to achieve in C++98? Or in C++11/14?</p> | 3 |
Tensorflow: Setting an array element with a sequence | <p>I'm trying to train a CNN using my own image dataset, but when passing the batch data and label to the <code>feed_dict</code> I get the error <code>ValueError: setting an array element with a sequence</code> from what I read <a href="https://stackoverflow.com/questions/34156639/tensorflow-python-valueerror-setting-an-array-element-with-a-sequence-in-t">here</a>, this is a dimension issue, and probably coming from my <code>batch_label</code> Tensor, but I couldn't figure out how to make it a one-hot Tensor (what my graph expects).</p>

Google Compute Startup Script PHP Files From Bucket | <p>I'd like to automatically load a folder full of php files from a bucket when an instance starts up. My php files are normally located at <code>/var/www/html</code></p>
<p>How do I write a startup script for this?</p>
<p>I think this would be enormously useful for people such as myself who are trying to deploy autoscaling, but don't want to have to create a new image with their php files every time they want to deploy changes. It would also be useful as a way of keeping a live backup on cloud storage.</p> | 3 |

Oxmetrics, Matrices as input in loglikelihood function (GARCH) | <p>I'm trying to write a program in Oxmetrics that estimates a multivariate GARCH model.
My multivariate GARCH model has the unconditional covariance matrix (should be the X variable) as input, but i'm unsure about how to correctly specify the correct matrix at each iteration.</p>
<p>My program looks as follows for now:</p>
<pre><code>//Global variable; visible also in the likelihood function
decl X;
//Likelihood contributions
garch_likelihood_contributions(likval_t, par)
{
//Local variables
decl covar, lik, H,C,A, i;
//Parameters
C = par[0];
A = par[1];
//conditional covariance sequence
H = constant(.NaN,2,2);
H = C*C'+ exp(-A)*H[0][]+A*exp(-A)*X[0][];
H[][0] = 0; //Initial value
X[][0] = sumc(covar[m])/2071; // Not correct specified yet, should be the sample average of the covariance matrices //
for(decl i=1; i<columns(X); ++i)
{
H[0][i] = C*C'+ exp(-A)*H[i-1][]+A*exp(-A)*X[i-1][];
}
//likelihood contributions
lik = constant(.NaN,columns(X),1);
lik[0] = 0.5*log(determinant(H[][i-1]))+ 0.5*X[1][]*invert(H[][i-1])*X[1][]';
for(decl i=1;i<2071;++i)
{
lik[i] = 0.5*log(determinant(H[][i-1])) + 0.5*X[i-1][]*invert(H[][i-1])*X[i-1][]'; // her stod X[i+1]
}
// adFunc[0] = lik;
// return !ismissing(adFunc[0]);
}
decl likval_t;
//Return vector of likelihood-contributions
likval_t[0] = lik;
//Return success
return 1;
}
//Likelihood function
garch_likelihood(par, likval, avScore, amHessian)
{
//Local variables
decl likval_t;
//Likelihood contributions
garch_likelihood_contributions(&likval_t, par);
//Return likelihood-value
likval[0] = double(sumc(likval_t));
//Return success
return 1;
}
main()
{
//Declare variables
decl data;
decl loglik, par;
decl C, A, covar;
decl vol, r, S_t, K, P;
//Load data:
data = loadmat("covariances.in7")';
P = data[0][0:];
covar = data[0:1][0:];
X = constant(.NaN,2,2);
for (decl i = 0, i < columns(P), i+2 )
{
j[i] = <0,2;0,2>
X[i]= vech(j[i]);
}
//Initial values for parameters
par = 0.1|0.5; //i.e. (omega, alpha, beta). Try out different starting values!
//Settings for likelihood estimation
MaxControlEps(1e-6,1e-4);
MaxControl(20000, 1, 1);
//Maximize likelihood function
print("\n\n","Maximizing likelihood: \n");
MaxBFGS(garch_likelihood, &par, &loglik, 0, 1);
print("%r",{"C","A"}
,"%c",{"MLE"},
par);
println("\nMaximized likelihood: ", loglik);
}
</code></pre>
<p>Inside the main, you should noticed that I have tried to specify the variable X as a 2x2 matrix for each iteration. The idea is that for each i, the loop should allocate the 2 first cloumns and rows from the datasheet "covariances.in7" into X.
The step for the loop should be 2, such that i = 1,3,5,7 ect.</p>
<p>Please post your thoughts, it's really appreciated.</p>
<p>Best regards,</p>

Integrating AWS device farm with Jenkins | <p>I want to integrate my Jenkins build with AWS device farm. So, while creating a project on AWS device farm, it asks to upload the apk to test.

<p>Is this possible?</p> | 3 |
Load an exe file and set a variable from web page | <p>I have recently been making a game in Unity (C#) and at the start a variable is set to a number. The number is a seed which is used to generate a 2d world out of blocks. This means that if the number is 5 then it will generate the same world for everyone using the seed 5.</p>
<p>I would like to upload seeds to my webpage so when a user clicks a button, the compiled unity application (.EXE) opens and the "seed" variable is set to a certain number depending on which button is pressed. For instance I could make a button which loads the program with the seed variable set to '5', or I could load it with the seed variable set to number '8'. </p>
<p>I am wondering if this is possible due to the file being complied and if so how would I do it? I have the code to load a .EXE file here:</p>
<pre><code><a href="file:///C:\\Windows\\notepad.exe">Click me</a>

Fill Excel + populate active x comobo box from Microsoft Sql Management Studio database table | <p>I have an excel file I am trying to pull values in from a Microsoft SQL Database. I am trying to add values from a table using the table's ID and string value associated with that ID. I have run into an invalid argument error. I was able to add the xlVal if i declared the integer value and set the first item = 0, then i could add 1 to the xlVal to make each integer value unique but these values won't allow me to reference the specific row in the database if i want to pull the values back to update the database. Basically i am wondering if there is a way to set the pvargindex value = to my database ID value since i don't have an integer in my database starting with 0. I also tried adding a row (select type..., 0) before the loop ran but i was unable to get this to work either.</p>
<pre><code>Private Sub populateType()

text which loaded from mysql server doesn't appears at list view | <p>I'm trying to build an android app which receive data from MySQL database into android app.
I followed this tutorial :
<a href="http://www.geeks.gallery/simple-json-parsing-example-in-android-part-iii/" rel="nofollow">http://www.geeks.gallery/simple-json-parsing-example-in-android-part-iii/</a></p>
<p>the problem appears as I'm clicking on button which load the data into listview, for some reason the text doesn't appear in that list.
as I followed the code, I acutely saw that the correct data is inserted to the corresponded relevant hash map "oslist".</p>
<p>any suggestions?
thanks,

Rails - Modular many-to-many relations | <p><strong>Context</strong></p>
<p>In the context of a Ruby on Rails application, in a school's project.</p>
<p>Let's consider the context of a team-based game, with many characters to choose from. I want to represent affinities between two characters in different context, which means whether two characters are being teamed-up or are facing each other or even when one is present in the game while the other is missing.</p>
<p>I would then have tables that looks something like this in my database</p>
<ul>
<li>Characters</li>
<li>Ally-Relation</li>
<li>Enemy-Relation</li>
<li>PlayingSingle-Relation</li>
</ul>
<p>Each of these <code><name>-Relation</code> tables represents a many-to-many relation between Characters, with an additional score that represents the strongness of the relation</p>
<p>Of course, relations between character are subject to changes. We might decide for any reason that a relation has become irrelevant, or another relation that we didn't thought of before just appeared.</p>
<p>In terms of display, we want to look for both the best and worst other characters in a specific relation.</p>
<p><strong>Question</strong></p>
<p>I came up with something like this.</p>
<pre><code>class Relation < ActiveRecord::Base
scope :best, ->(character_id) {
Character.find(where(character_left: character_id).order("score desc").limit(5).pluck(:character_right))
}
end
</code></pre>
<p>Where <code>character_left</code> and <code>character_right</code> are the two characters to be considered for in the relation and the score is the strenght of the bond.</p>
<p>However, when fetching data, my teacher thinks it would be best to have scopes in the Characters model to find both the best and worst other character in a specific relation. This, because the teammate that is doing, say, the HTML code don't give a damn about the structure of the Relations when he wants to display characters. He told me about using <code>has_and_belongs_to_many</code> and he sketched me some code he would expects that looks something like <code>Character.best(:relation)</code> to fetch the data.</p>
<p>While I think what I did is better (obviously :) ). Having the scopes that will fetch Characters from within the Relation models, as they subject to appear and disappear keeps the request relation specifics. This prevents us from modifying the Characters model every time we fumble with the Relations.
Having somethings that looks like <code>Relation.best(:hero)</code> seems cleaner to me.</p>
<p>What do you think about it ? What are good practices around this very specific situation. Are there any right way to apply and use modular many-to-many relation s in a Ruby on Rails application ?</p> | 3 |
Header set Content-Security-Policy not handling multiple domains correctly | <p>I'm trying to protect from XSS attacks under Apache setting the following directive:</p>
<pre><code>Header set Content-Security-Policy "default-src 'self' code.jquery.com;"
</code></pre>
<p>to only allow the jquery.com CDN which is quite handy.
However the directive keeps giving me in Firefox the following:</p>
<blockquote>
<p>The page's settings blocked the loading of a resource at self
("script-src <a href="http://www.website.com" rel="nofollow">http://www.website.com</a> <a href="http://code.jquery.com" rel="nofollow">http://code.jquery.com</a>").</p>

Inconsistent behaviour of conf.setLocale() | <p>As per the given <a href="https://stackoverflow.com/a/2900144/5754623">solution</a>, I'm using the following code to change the language programmatically:</p>
<pre><code> DisplayMetrics dm = res.getDisplayMetrics();
Configuration conf = res.getConfiguration();
if (Build.VERSION.SDK_INT >= 17) {
conf.setLocale(newLocale);
} else {
conf.locale = newLocale;
}
res.updateConfiguration(conf, dm);
</code></pre>
<p>I'm calling this in <code>onCreate()</code> in each activity before <code>setContentView()</code> and after <code>super.Oncreate()</code>.</p>
<p><code>conf.setLocale()</code> internally calls <code>setLayoutDirection()</code> and is supposed to change the layout direction according to the specified <code>locale</code>. But it's behaviour is not consistent. The layout direction gets overridden by the system frequently. What should be the workaround for this? </p>
<p>Any help would be greatly appreciated.</p> | 3 |
Inheritance with two abstract classes | <p>Im trying to create an arraylist that contains at least two instances of each class, I need to achieve this using a single arraylist. The problem is the class HourlyWorker and ContractWorker both implement the abstract class Smarty where the Class Hobbit implements the abstract class Simpleton and i cant figure out how to use both in one arraylist.</p>
<pre><code>public class MainClass {
private ArrayList<Smarty> list;
public MainClass() {
list = new ArrayList<Smarty>();
list.add(new HourlyWorker("Bob", 50, 40, 8.0));
list.add(new HourlyWorker("Bill", 70, 50, 12.0));
list.add(new ContractWorker("Jill", 80, 8, 100.0));
list.add(new ContractWorker("Amy", 125, 12, 85.0));
list.add(new Hobbit("Frodo", 12));
list.add(new Hobbit("Merry", 8));
