Add animated jquery fade or slide effect to backgroundimage slider | <p>I would like to change this jQuery background image script so that the images will fade-in and fade-out smooth or by sliding one in or out.</p>
<p>Right now the new image just pops-in what doesn't look good.
Also can't figure out how to make the images load random.</p>
<pre><code>(function ($) {
var count = 0;
var milliseconds = 4000;
var transitionTime = 1500;
var selector = "#target";
setInterval(function () {
var images = ["images/pic1.png", "images/pic2.jpg"];
var tempImage = new Image();
tempImage.src = images[count];
$(tempImage).on("load", function () {
$(selector).css("opacity", "0")
.animate({ opacity: 1 }, { duration: transitionTime });
$(selector).css("background-image", "url(" + tempImage.src + ")");
});
if (count < images.length - 1) {
count++;
}
else {
count = 0;
}
}, milliseconds);
})(jQuery);

Adding punctuation in nested templates | <p>I am trying to add elements with a comma and a space in <code><album></code> if it is not the last <code><album></code> within a parent <code><recording></code>.</p>

Import from execution path | <p>I have a setup like this:</p>
<pre><code>projectpath/__main__.py
projectpath/backend/__init__.py
projectpath/backend/backend1.py
projectpath/backend/backend2.py
</code></pre>
<p>The <code>__main__.py</code> imports and uses both backend files and <code>backend2.py</code> also imports and uses <code>backend1.py</code>. I used to do it like so:</p>
<p><code>__main__.py:</code></p>
<pre><code>import backend.backend1
import backend.backend2
</code></pre>
<p><code>backend2.py:</code></p>
<pre><code>import backend1
</code></pre>
<p>And that worked, but now I am using mypy (Python static type checker), and that one requires all import paths to be relative to the <code>__main__.py</code>, so my backend2.py now looks like this:</p>
<pre><code>import backend.backend1 as backend1
</code></pre>
<p>mypy now says this is fine, but when I try to execute it, I get the following error:</p>
<pre><code>Traceback (most recent call last):
[...]
File "./backend/backend2.py", line 1, in <module>
import backend.backend1 as backend1
</code></pre>
<p>Is there any way to allow imports in that style, so allowing imports from the execution path of <code>__main__.py</code>?</p> | 3 |

Aurelia repeat.for for - some questions | <p>I am attempting to generate a form like this:</p>
<pre><code><div class="col-xs-6" for.repeat="field in ${config.formMain}">
<div class="form-group">
<label>${field.label & oneTime}</label>
<select if.one-time="field.controlType == 'select'" class="form-control">
<option value=""><- Select -></option>
</select>
</div>
</div>
</code></pre>
<p>where config is a variable in my view-model. </p>
<p>A couple questions:</p>
<p>1) I have tried both <code>for.repeat="field in ${config.formMain}"</code> and <code>for.repeat="field in config.formMain"</code> and neither syntax seems to work. How am I meant to access the array from the object?</p>
<p>2) Is there any support for something like <code>for.repeat.one-time="field in ${config.formMain}"</code> where this would cause Aurelia to only execute the loop compilation once (which is useful in my case because the form is not going to chage) but keep the bindings inside the loop as default bindings (i.e. if I have a for.repeat inside of the outer one, it should update itself if the array it is iterating over changes)?</p>
<p>Thanks in advance.</p> | 3 |
Push holidays in users' calendar | <p>In our current environment, our employees book holidays in an SAP portal. There's a separate script that will send these holidays to the users' email calendar (currently Zimbra), so it's already filled in.</p>
<p>Now we're currently migrating to Office 365, and we need to change our script. First glance was good, there's a pretty solid REST API available with methods that will do the job just fine.</p>
<p>Unfortunately, the whole thing requires OAuth2. In our scenario, we won't be having any user interaction, we'd really want to use static credentials.</p>
<p>I've been doing some googling, but to no avail. Is there a proper solution to our use case, without having to do anything dirty?</p>
<p>Side-note: we'd like to use Java to get this done. But I find even less documentation about that. The EWS API looks like a potential solution, but it looks pretty deprecated.</p> | 3 |

AWS : monitoring if service is running | <p>We are using zabbix to monitor our instance, during the the instance creation chef-recipes install and register zabbix. We have modified the zabbix recipe to by-pass registration if it fails, so that the rest of the services are deployed and are functional. Is it possible to set up alarms in AWS to check if zabbix registration is successful ? In other word, how to setup custom monitors for a instance ?</p> | 3 |

MDB concurrent instances not starting | <p>I have a requirement where i need 40 threads to do a certain task (merging) and around 20 threads to do another task(persistence). Merging takes about 5X more time than persistence.
I am using message driven beans to accomplish this concurrency.</p>
<p>I created one MDB RecordMerger with the following configuration</p>
<pre><code>@MessageDriven(activationConfig = {
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
@ActivationConfigProperty(propertyName = "destination", propertyValue = "testing/RecordMerger"),
@ActivationConfigProperty(propertyName = "maxSessions", propertyValue = "40")
})
</code></pre>
<p>and I did similar thing for persistence</p>
<pre><code>@MessageDriven(activationConfig = {
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
@ActivationConfigProperty(propertyName = "destination", propertyValue = "testing/RecordPersistor"),
@ActivationConfigProperty(propertyName = "maxSessions", propertyValue = "20")
})
</code></pre>
<p>My configuration in tomee.xml is as follows</p>
<pre><code> <Container id="MyJmsMdbContainer" ctype="MESSAGE">
ResourceAdapter = MyJmsResourceAdapter
InstanceLimit = 40
</Container>
</code></pre>
<p>The recordmerging queue has a very fast production, so there are always new elements in record merging queue. Record merging queue puts the data in Record Persistence queue.</p>
<p>The problem that i am facing is that when record merger has been configured to use 40 threads, my tomee server does not instantiates record persistence MDB, which results in records being piled up in that queue. If i reduce the maxSession property of record merger to 20, both the MDB's start getting instantiated.</p>
<p>Can any one please guide me what i need to do to ensure that both MDB's are running and record merger is having 40 threads.</p> | 3 |

whats the difference between cache & http cache "reverse proxy" | <p>am having a bit of difficulty understanding the difference between the normal cache "memory,file,db,etc.." and the http caching "reverse proxy".</p>
<p><strong>Example.</strong></p>
<p>lets say i have a page divided into 3 parts.</p>
<ul>
<li>movies</li>
<li>games</li>
<li>apps</li>
</ul>
<p>and when i retrieve those parts from the db, i cache each part in its own key & when a new data is entered to any of those parts i flush the cache and remake it including the new data, so now each part will only update if there is something new was added.</p>
<p>on the other hand the http caching have something call <code>ESI</code> which u can include page partials that have a different cache life span from the main page which is perfect but </p>
<p>why would i need to use it ?
or what is the advantage over the first method ?</p>
<p><strong>Edit</strong> </p>
<blockquote>
<ul>
<li>this is slimier to what i was after but still, why would u use/continue to use the reverse proxy over the below ?</li>
</ul>

Will tarantool helps in OpenVZ? | <p>I have a small OpenVZ container.
2 cores and 4096MB RAM.</p>
<p>I have mysql database (overal size is 80MB InnoDb)</p>
<p>When i do 100 queries like INSERT ON DUPLICATE KEY UPDATE, few of them executes longer than 1 seconds, always</p>
<pre><code>mysql> SHOW PROFILE;
+----------------------+----------+
| Status | Duration |
+----------------------+----------+

7 rows in set (0.00 sec)
</code></pre>
<p>When i turned off binary logging, it helped. So the problem maybe in hard drive. And occurs when binary log is writing during the query executing.</p>
<p>Will it help, if i replace mysql with the tarantool? As i know tarantool also writes binlogs.</p>

Software located on different server as Database | <p>The question I have, is pretty simple, but though I want to know if someone as a better solution.</p>
<p>The problem I have, is putting the MySQL database on a differen Server than the Software itself.
I've heard, that there are security issues when declaring a different host than the "localhost" for the database, so I'm asking If any of you know of an answer or has an idea of how to deal with it.</p>
<p>The Idea behind this task is the following:</p>
<p>If I provide software to a customer, but don't want them to have access to the Source Code (which is pretty simple when the server is in their office), I put it on my own server and give them access to it.
Then the customer says that they don't want us to have access to their data, they store in the database.</p>
<p>So my question now is, how it's possible to have a solution which fits both needs. Mine, and those of the customer.</p>
<p>I hope you can understand what I mean.</p>
<p>Thank you for your help!</p> | 3 |
Posting Quickbooks Online invoice without using CustomerRef | <p>How do I create an invoice in QBO without using the CustomerRef field? Every example just shows:</p>
<pre><code><CustomerRef name="ACME Inc">2</CustomerRef>
</code></pre>
<p>Do I ALWAYS have to look up the Id? Can't I just post to "ACME Inc" without finding the ref # (2)? The older QBXML did this no problem.</p>
<p>Similarly for items, they all have it like this:</p>
<pre><code><ItemRef name="Hours">2</ItemRef>
</code></pre>
<p>How do I just specify "Hours" and have QB look it up for me?</p> | 3 |

Ajax appended content selectors not responding | <p>I have a very peculiar problem where i'm get loading some content through ajax and then appending some more content to the newly added content</p>
<p>I'm going to try an explain the scenario.</p>
<p>First Ajax call</p>
<pre><code> $.ajax({
url: href ,
dataType: 'html',
success: function(data) {
var response = $(data).find('#content').html();
$('#content').append(response)
}
});
</code></pre>
<p>For simplicity sake lets assume that the content appended to the div content is </p>
<pre><code> <div id="wrap"></wrap>
</code></pre>
<p>2nd Ajax Call ( some api )</p>
<pre><code>$.ajax({
url: "https://api.tumblr.com/v2/blog/sometumblr.tumblr.com/posts?api_key=someapikey",
dataType: 'jsonp',
success: function(posts) {
var postings = posts.response.posts,
output = '';
for (var i in postings) {
var p = postings[i];
output += '<div class="p"><div class="photo"><img src=' + p.photos[0].original_size.url + '/></div></div>';
}
$.when($('#wrap').append(output)).then( masonry());
}
});
</code></pre>
<p>Masonry is a function that will be called after the output variable has been appended.</p>
<p>The issue here is, because the div wrap was appended to the DOM i'm not able to select it and then append the new content in the variable content. I'm aware of event delegation and jquery's .on() function but they all require an event to be passed. Unfortunately .prepend or .html() don't need event handlers so it would not work.</p>
<p>I've seen other nifty solutions using jquery's trigger and a custom event however in the masonry() function i need to pass the selector $('#wrap') as well so that solution would not suffice. Is the away to attach newly appended content to the DOM so that they can be used in the normal way.</p>
<p>i.e is append</p>
<pre><code> <div id="wrap"></wrap>
</code></pre>
<p>and can use </p>
<pre><code> $('#wrap).html('some stuff')
</code></pre>
<p>Any pointers would be deeply appreciated.</p> | 3 |

Using htonl/ntohl on a 32 bit integer that will be sent over a socket | <p>When I look up examples for htonl, it always returns a <strong>uint32_t</strong>. However, when I call htonl in VS2015 using Winsock2.h, it returns a <strong>u_long</strong>. </p>
<p>On my machine, when I compile for 32 bit and for 64 bit, I get that the size of a u_long is 4 bytes. I read online, that in a 64 bit architecture a long should be 8 bytes. Will this ever be the case? I am worried that I will have compatibility issues if a u_long is not the same amount of bytes as uint32_t when the data is to be sent over the socket.</p>
<p>TL;DR - Will a u_long always be 4 bytes? If not, how should you reliably send a 32 bit integer over a socket?</p> | 3 |
zeromq 4.0 with openpgm: How can i use "pgm_setsockopt" to change PGM_MULTICAST_LOOP | <p>I try to change a socket option (PGM_MULTICAST_LOOP) in zeromq with openpgm support. There is a dedicated function 'pgm_setsockopt' to do that but its first argument is a pgm_sock_t * and my original socket is a void * obtained by pSubscriber = zsocket_new(_pZmqContext_X, ZMQ_SUB);
If I call 'pgm_setsockopt' by casting pSubscriber to (pgm_sock_t *) it does not work.
The question is: how do I "transform" a zsocket_new result pointer into a pgm_sock_t socket which can be used to call 'pgm_setsockopt' </p>
<p>Thanks</p> | 3 |
Dynamic generation of tests for an ActiveSupport::Concern | <p>I have a Concern defined like this:</p>
<pre><code>module Shared::Injectable
extend ActiveSupport::Concern
module ClassMethods
def injectable_attributes(attributes)
attributes.each do |atr|
define_method "injected_#{atr}" do
...
end
end
end
end
</code></pre>
<p>and a variety of models that use the concern like this:</p>
<pre><code>Class MyThing < ActiveRecord::Base
include Shared::Injectable
...
injectable_attributes [:attr1, :attr2, :attr3, ...]
...
end
</code></pre>
<p>This works as intended, and generates a set of new methods that I can call on an instance of the class:</p>
<pre><code>my_thing_instance.injected_attr1
my_thing_instance.injected_attr2
my_thing_instance.injected_attr3
</code></pre>
<p>My issue comes when I am trying to test the concern. I want to avoid manually creating the tests for every model that uses the concern, since the generated functions all do the same thing. Instead, I thought I could use rspec's <code>shared_example_for</code> and write the tests once, and then just run the tests in the necessary models using rspec's <code>it_should_behave_like</code>. This works nicely, but I am having issues accessing the parameters that I have passed in to the <code>injectable_attributes</code> function.</p>
<p>Currently, I am doing it like this within the shared spec:</p>
<pre><code>shared_examples_for "injectable" do |item|
...
describe "some tests" do
attrs = item.methods.select{|m| m.to_s.include?("injected") and m.to_s.include?("published")}
attrs.each do |a|
it "should do something with #{a}" do
...
end
end
end
end
</code></pre>
<p>This works, but is obviously a horrible way to do this. Is there an easy way to access only the values passed in to the injectable_attributes function, either through an instance of the class or through the class itself, rather than looking at the methods already defined on the class instance?</p> | 3 |
Image change between view templates stopping onclick dropdown menu? | <p>I placed an onclick dropdown menu in my top navigation bar. In the top navigation bar, I wanted to change this image in my <strong>new.html.erb</strong> view template: </p>
<pre><code><li class="navigation-bar-right"> <span class="create"> <%= link_to image_tag("createpost.svg"),new_post_url, method: :get %> </span> </li>

How to filter rows based on criteria | <p>Consider this toy example where I have a very simple SQL table containing some partnumbers, prices and currency. I want to find the lowest price for each item. </p>
<p>Hers is table <code>PRICELIST</code></p>
<pre><code>PartNumber Price Currency
1 19 USD
1 10 CAD
1 18 GBP
2 15 USD
2 14 CAD
2 8 GBP
3 5 USD
3 1 CAD
3 11 GBP
</code></pre>
<p>I want to show the lowest price with the currency. This is the output I want:</p>
<pre><code>PartNumber Price Currency
1 10 CAD
2 8 GBP
3 1 CAD
</code></pre>
<p>if I say <code>select partnumber, min(price) from pricelist group by partnumber</code></p>
<p>the query will execute, but if I specify the currency:</p>
<p><code>select partnumber, min(price),currency from pricelist group by partnumber</code></p>
<p>Then I get an error saying: </p>
<p>An expression starting with "CURRENCY" specified in a SELECT clause, HAVING clause, or ORDER BY clause is not specified in the GROUP BY clause or it is in a SELECT clause, HAVING clause, or ORDER BY clause with a column function and no GROUP BY clause is specified..</p>
<p>I want to display the currency value for the row that has the lowest price. What should I do?</p>
<p>database is DB2. </p>
<p>By the way, this is a highly simplified example, in my actual query I have left joins to create larger sets, if that matters</p> | 3 |

Access - If form maximized then allow scrollbars | <p>I have found this API that checks whether form is maximized :
<a href="https://support.microsoft.com/en-us/kb/210190" rel="nofollow">ACC2000: How to Determine If a Form Is Maximized or Minimized</a></p>
<p>Now I want to use this API to allow Scrollbars on form, If It's maximized. Problem is that when It get's maximized, scrollbars are not visible until I click on some control in detail section. Same way when form is restored - scrollbars don't dissapear until I click on some control. Any way to fix this ?</p>
<p>I tried this (I have to click Field1 after this code, focus not working):</p>
<pre><code>Private Sub Form_Current()
If Maximized = True Then
Me.ScrollBars = 2
Else
Me.ScrollBars = 0
End If
Me.Field1.SetFocus
End Sub

<p>and this (when seting Me.TimerInterval=0 nothing happens, otherwise It's working but keeps triggering timer event):</p>

How to alter the visual behavior of a ListViewItem in UWP? | <p>In UWP, every time a <code>ListViewItem</code> is selected, a storyboard is triggered to give the user the feeling the component is reacting to the pressure of a touch. That storyboard also changes the <code>ListViewItem</code>'s background color until it gets released.</p>
<p>I have designed a <code>UserControl</code> which uses a <code>ListView</code> internally but would like to override this behavior as it doesn't really fit the application's proposed design.</p>
<p>Bellow are the <code>VisualStateGroups</code> I tried to apply both to the <code>ListView</code> through its <code>ControlTemplate</code> and to <code>ListViewItem</code> through its <code>DataTemplate</code> definition as the former attempt failed.</p>
<pre><code><VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal" />
<VisualState x:Name="PointerOver" />
<VisualState x:Name="Pressed" />
<VisualState x:Name="PointerOverPressed" />
<VisualState x:Name="Disabled" />
</VisualStateGroup>
<VisualStateGroup x:Name="FocusStates">
<VisualState x:Name="Focused" />
<VisualState x:Name="UnFocused" />
<VisualState x:Name="PointerFocused" />
</VisualStateGroup>
<VisualStateGroup x:Name="SelectionStates">
<VisualState x:Name="Unselecting" />
<VisualState x:Name="Unselected" />
<VisualState x:Name="UnselectedPointerOver" />
<VisualState x:Name="UnselectedSwiping" />
<VisualState x:Name="Selecting" />
<VisualState x:Name="Selected" />
<VisualState x:Name="SelectedSwiping" />
<VisualState x:Name="SelectedUnfocused" />
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
</code></pre>
<p>One possibility could be to bind the root grid of the <code>DataTemplate</code> to the <code>ItemsContainer</code> so that I could override the default behavior every time an item was selected. But I am not that versed in XAML and couldn't figure out the proper way of doing this by myself. </p> | 3 |
What's the consequence of not adding "@Override"? | <p>Based off of <a href="https://stackoverflow.com/questions/94361/when-do-you-use-javas-override-annotation-and-why">this well loved question</a> I understand that the @Override annotation is a good coding practice so that we know we are actually Overriding the correct method. But, what's the consequence of not doing it, other than coding practice? Is there some underlying thing in Java that needs that annotation there?</p>
<p>I'm asking because I'm generating Java ActiveMQ Message files from XSD files using <a href="https://jaxb.java.net/2.2.4/docs/xjc.html" rel="nofollow noreferrer">XJC</a>. But, in order to add "@Override" without doing hand edits I need to use a separate plug-in from what's available from XJC, which in my case is quite <a href="https://stackoverflow.com/questions/33525642/how-to-use-jaxb2-annotate-plugin-with-xjc-in-command-line">difficult knowing the dependencies</a>. The primary goal is to use XJC and my Ant build.xml to regenerate the Java message files at build time without any hand edits. </p> | 3 |
Dinamic headers in Retrofit (1-2) do not work | <p>I'm trying to make authtoken <strong>GET</strong> request to my server.

@GET("/auth/me/")
Observable<User> me(@Header("Authorization: Token") String token); //this does not work at all!
Observable<User> me();

WordPress wpautop Not Working Inside Wrapper | <h1>Background</h1>
<p>I am extending TinyMCE in the WordPress visual editor, and have added a button to wrap selected content in <code><section></section></code>, which is used on the front-end of my theme for a hero element.</p>
<hr />
<h1>Problem</h1>
<p>When I wrap text inside <code><section></code> tags, wpautop stops running. The <code><p></code> tags aren't added at all, which breaks things when the selection is multiple paragraphs worth.</p>
<h3>Example:</h3>
<p>This text is in the Text editor (not visual editor).</p>
<pre><code><section>This is paragraph one. This is paragraph one.
This is paragraph two. This is paragraph two.</section>
</code></pre>
<p>On the front end of the site, it should become:</p>
<pre><code><section><p>This is paragraph one. This is paragraph one.</p>
<p>This is paragraph two. This is paragraph two.</p></section>
</code></pre>
<p>No <code><p></code> tags are added though.</p>
<h1>What I've Tried:</h1>
<p>I've tried forcing the issue by putting in breaks myself, but they all just get removed.</p>
<pre><code>var output = '<section><article>' + text + '</article></section>';
var output = '<section><article><p>' + text + '</p></article></section>';
var output = '<section><article><br>' + text + '</br></article></section>';

Disabling Table of Contents links in Qualtrics | <p>I'm trying to customize a survey I'm building on Qualtrics so that certain items in the Table of Contents are disabled. Basically I want you to be able to use the TOC to navigate to previous pages, but not to be able to click on subsequent pages. This is not something I can customize just using the Qualtrics menu.</p>
<p>I'm trying to add Javascript to each block to enable this feature, but can't get it to work. I looked into the html elements on my page and under a div labeled "ToC Sidebar", each element of my ToC is there with a unique id (e.g. "FL_34"), and there's an 'onclick' function under this element to go to link's page. I just want to set this to false. Apologies if this is obvious, I'm new to Qualtrics and Javascript.</p>
<p>Here's what I have right now, any thoughts?</p>

TFSBuild Powershell step turning script arguments into strings. How to avoid this? | <p>I've configured the following arguments in a Powershell build step: <code>-protocol:http -portsToOpen 9512,9513,9512</code>.</p>
<p>Once TFSBuild runs the whole script, it throws the following error:</p>
<blockquote>
<p>"System.Int32[]". Error: "Cannot convert
"9512,9513,9515" to "System.Int32"</p>
</blockquote>
<p>The problem is TFSBuild is running the script sorrounding 9512,9513,9515 with quots (i.e. <code>'9512,9513,9515'</code>).</p>
<p>Is there any solution for this? One possible workaround would be running <code>powershell.exe</code> from a Command build step... But I'd like to know if there's some direct solution to this issue.</p> | 3 |
ActorRefs.Nobody being translated by remoting | <p>I'm using Akka.Remote to call from an ASP.NET web application to an actor in my back end (hosted as a Windows Service). As part of the code I'm looking up an actor on the remote system which may or may not exist.</p>
<p>On the client the call is as follows...</p>
<pre><code>var profileActor = await someRemoteActor.Ask<IActorRef>(new LoadProfile("[email protected]"));
if (profileActor != ActorRefs.Nobody)
{
// Now do stuff with the profile
...
}
</code></pre>
<p>On the remote side of things the code is doing this...</p>
<pre><code>Receive<LoadProfile>(rq =>
{
IActorRef child = ActorRefs.Nobody;
if (ProfileExistsInTheDatabase(rq.Username))
{
child = Context.ActorOf<Profile>(rq.Username);
child.Tell(rq);
}
Sender.Tell(child);
};
</code></pre>
<p>This isn't the exact code, but shows the idea that if something is not found on the server side then ActorRefs.Nobody is returned.</p>
<p>Now, the problem is that when ActorRefs.Nobody gets back to the client, it's been converted into a remote actor reference, which I wasn't expecting. I was expecting ActorRefs.Nobody to traverse the remoting layer and turn up as the same thing on the client. </p>
<p>Am I wrong to expect this to work this way? I guess so, given that it doesn't work the way I expected, but some clarification would be nice.</p>
<p>For now I've altered the code to return a message class that includes a flag to indicate whether the remote actor exists, but I'd rather be able to use ActorRefs.Nobody.</p>
<p>Thanks in advance for your assistance. </p> | 3 |

How to pass object into function in JavaScript | <p>I am doing my assignment about ASP.NET MVC and ASP.NET WEB API
I have database like:</p>
<pre><code>ID, FirstName, Middle, LastName, DoB, Gender.

I write a function <em>DoubleClickRow</em> like:</p>
<pre><code><script language="JavaScript">
function *DoubleClickRow*(thisRow)
{
var id = thisRow.ID //Get ID from a row with double click event but it does not shown on table.
location.href="~/Employees/Details/ + "id" //Open a new page to display employee detail with id above.
}
</script>
</code></pre>
<p>And a table like:</p>
<pre><code> <table class="table">

The django-markdown-bootstrap-widget is not showing properly | <p>I am django beginner and I have the following Problem.

<code>name</code> and <code>name2</code> are displayed correctly with the markdown-editor.

C# Unload temp Appdomain while main Appdomain uses MethodInfo from temp | <p>I want to make a reloadable assembly function for scripting.(So i can debug scripts quicker)</p>
<p>The dll generation works and loading too. The main problem is, that I`m using the functions of my temporary AppDomain in my main AppDomain. The dll seems to be linked to my main AppDomain too, because I cant delete it while the program is running.
If I remove all MethodInfo references from my main AppDomain "context" then I have no problems deleting it.</p>
<p>Here you can see how the program works:</p>
<ul>
<li>Generate DLL from external process</li>
<li>Load DLL by (temp AppDomain).DoCallBack(...)</li>
<li>Get Type & MethodInfo and call it.</li>
<li>AppDomain.Unload(temp AppDomain)</li>
</ul>
<p>So if I skip step 3, I have no problems deleten the dll. But I cant check if the return of the Function really shows the updated value (which i edit inside the script). </p>
<p>I have posted the source code for each step here:
1.</p>
<pre><code>//This actually isn`t as important for you
Process assemblyGeneration = new Process();
assemblyGeneration.StartInfo.FileName = AppDomain.CurrentDomain.BaseDirectory + @"lib\AssemblyCompiler.exe";
assemblyGeneration.StartInfo.Arguments = "\"" + AppDomain.CurrentDomain.BaseDirectory + "script.dll\" \"" + source + "\" \"System.dll\"";
assemblyGeneration.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
assemblyGeneration.StartInfo.UseShellExecute = true;
assemblyGeneration.Start();
assemblyGeneration.WaitForExit();
assemblyGeneration.Dispose();
</code></pre>
<p>2.</p>
<pre><code> _appDomain.DoCallBack(() =>
{
byte[] fileContent = File.ReadAllBytes(AppDomain.CurrentDomain.BaseDirectory + "script.dll");
AppDomain.CurrentDomain.Load(fileContent);
});
</code></pre>
<p>3.</p>
<pre><code>MethodInfo info = _compiledScript.GetTypeFrom("LSCT.ScriptClass").GetMethod("DefineX");
var func = (Func<double>) Delegate.CreateDelegate(typeof(Func<double>), info);
double x = func();
Console.WriteLine("Output was : " + x);
</code></pre>
<p>4.</p>
<pre><code>AppDomain.Unload(_appDomain);
</code></pre>
<p>So is there a way to work around the issue, that I cant reload the DLL?</p> | 3 |

How do EGit versions map to Git versions | <p>The Git Source Code Mirror on GitHub (<a href="https://github.com/git/git" rel="nofollow">https://github.com/git/git</a>) says that the most recent version of Git is 2.7.4. I'm using EGit 3.5.2 on Spring Tool Suite (Eclipse Luna SR1), so that version number obviously doesn't correspond to a Git version. Is there any way to trace back what version of Git this version of EGit is based off of? </p>
<p>I checked here, but it only maps versions of EGit to versions of Eclipse...</p>

Django query on child records without getting duplicate rows | <p>I'm trying to write a Django query to find a set of parent records with certain kinds of child records. The problem is that a parent record with two children that match the search will included twice in the results.</p>
<p>How can I get each parent once, even when it has more than one matching child?</p>
<p>I've included a simple example below that demonstrates the problem. <code>Blog</code> is the parent, and <code>Entry</code> is the child. When I search for blogs that contain an entry with "Hello" in the title, I get two copies of Jimmy's blog.</p>
<p>Here are the records I created and the query I tried:</p>
<pre><code> b = Blog(name="Jimmy's Jottings")
b.save()
Entry(blog=b, headline='Hello, World!').save()
Entry(blog=b, headline='Hello Kitty').save()
blog_count = Blog.objects.filter(entries__headline__contains='Hello').count()
assert blog_count == 1, blog_count
</code></pre>
<p>You can see there's only one blog, but the assert fails with a count of two.</p>

Cairo: grabbing the whole drawing as a pattern | <p>I am probably missing something conceptual about <code>cairo</code>. I draw using the following helper class:</p>
<pre><code>struct GroupLock {
GroupLock(Graphics &g) : g_(g) {
cairo_push_group(g_.cr);
}
~GroupLock() {
cairo_pop_group_to_source(g_.cr);
cairo_paint(g_.cr);
cairo_surface_flush(g_.surface);
XFlush(g_.display);
}
private:
Graphics &g_;
};
</code></pre>
<p>All my drawing functions are of the form:</p>
<pre><code>void drawSomething(Graphics &g) {
GroupLock lock{g}; (void)lock;
... // some drawing
}
</code></pre>
<p>Each call to such a drawing function sets the <em>source</em> (by virtue of using <code>GroupLock</code>) and makes the previous <em>source</em> unreachable. How can I modify this code to "concatenate" the <em>source</em>s instead? I would like be able to grab the whole drawing as a pattern by doing:</p>
<pre><code>cairo_pattern_t *p_ = cairo_get_source(g_.cr);
cairo_pattern_reference(p_);

Is specifying a column from a named range more efficient than calculating over a complete column? | <p>Under the hood of <code>Excel</code> do you think if I use named ranges, for say <code>MAX</code> calculations, it will be more efficient e.g. </p>
<p>I have a named range <code>myNmdRang</code> that is <code>A1:Z20000</code> with no data in the remainder of the sheet. Column A contains some numeric values. The named range might get adjusted in length tomorrow to 500k rows or just 100rows.</p>
<p>Taditionally I do this to find the <code>MAX</code> in column 1:</p>
<p><code>Max("A:A")</code> </p>
<p>Is the following more efficient and/or takes up less storage? (can this be proved)</p>
<p><code>Max(index(myNmdRang,0,1))</code></p> | 3 |
How would one go about politely crawling a single website? | <p>I have recently taken an interest in web crawling and am aware of robots.txt guidelines, but I was interested in the specifics of what is considered "polite" in terms of pages processed per second and the number of threads that should be set crawling a single website at any given time. Any general guidelines are greatly appreciated as I don't want to be impolite, destructive, or risk getting blocked by a website.</p>
<p>Also, I realize different websites will experience different amounts of strain based on my crawling, so any advice on how I can properly gauge this and account for it is welcome.</p> | 3 |

<p>I have it in a file called startdev in a folder that is on my PATH variable (I'm on Windows 10), so I can open up a shell from anywhere and type in <code>startdev -g</code> or <code>startdev -g -h</code> to run this.</p>
<p>This all works, wonderfully I might add, when it opens the shell and sends the gulp command, it detects my gulpfile and is able to run the default task on it like I want it to. However, the http-server isn't doing the same thing, it just tells me <code>http-server ./ -p 8111: No such file or directory</code>.</p> | 3 |
Is it possible to use Unsafe.CompareAndSwap with a memory position rather an offset with an object? | <p>Most of the Unsafe operations accept a memory position in order to perform the operation - for example:</p>
<pre><code> Unsafe unsafe = Context.unsafe;
long position = unsafe.allocateMemory(8);
unsafe.putLong(position, 0);
</code></pre>
<p>However, the CAS operations as far a I can see do not offer this - they instead take an Object as one of the arguments:</p>
<pre><code> unsafe.compareAndSwapLong(this, offset, expected, newvalue)
</code></pre>
<p>However, given the long which is at the position "position", how can I perform a CAS operation without it being a field within an object?</p> | 3 |

<p>I have a service</p>
<pre><code>@Injectable()
export class MyService {
doSomething() {
console.log("This is a service, and it's doing stuff");
}
}
</code></pre>
<p>That can be injected into components, like this, without issue:</p>
<pre><code>@Component({
selector: 'parent-component',
template: '<p>This works great!</p>',
providers: [MyService]
})
export class ParentComponent {
constructor(private _myService: MyService) {}
ngOnInit() {
this._myService.doSomething();
}
}
</code></pre>
<p>I have problems, however, when I try to inject the service into nested components, like this:</p>
<pre><code>@Component({
selector: 'nested-component',
template: "<p>This doesn't work. :(</p>",
providers: [MyService]
})
export class NestedComponent {
constructor(private _myService: MyService) {}
ngOnInit() {
this._myService.doSomething();
}
}
</code></pre>
<p>When I try to plug the nested component into the parent component, I get the error up there ^. How can I achieve this.</p>
<pre><code>@Component({
selector: 'parent-component',
template: '<nested-component></nested-component>',
directives: [NestedComponent]
})
export class ParentComponent {
}
</code></pre>
<p>For what it's worth, I still run into that error, even when I include MyService in the bootstrap function of my app:</p>
<pre><code>function main() {
return bootstrap(App, [
// These are dependencies of our App
HTTP_PROVIDERS,
ROUTER_PROVIDERS,
MyService,
ELEMENT_PROBE_PROVIDERS // remove in production
])
.catch(err => console.error(err));
}
document.addEventListener('DOMContentLoaded', main);

Find which file declares bash environment | <p>Use case: adding <a href="https://github.com/bobthecow/git-flow-completion/wiki/Install-Bash-git-completion" rel="nofollow noreferrer">bash-completion</a> to dev-environment playbook.</p>
<p>In OSX, I need to write to either <code>.profile</code> or <code>.bash_profile</code> via Ansible. I need to add some config lines to one of those files and would like to do so to whichever one exists. I need to add those lines to the first of those files that exists since <a href="https://stackoverflow.com/questions/18773051/how-to-make-os-x-to-read-bash-profile-not-profile-file">OSX looks for <code>.bash_profile</code>, <code>.bash_login</code>, then <code>.profile</code> and stops looking when it finds one of them</a>.</p>
<p>Is there an environment variable I can use to determine which file was used to load the bash config?</p>
<p>Is there a way to create a variable in Ansible that tells Ansible which of those files to write to, depending on the first one in the list (<code>.bash_profile</code>, <code>.bash_login</code>, <code>.profile</code>) that exists?</p>
<p>I've tried this in my existing <code>playbook.yml</code>, which does not overwrite my initially stated var of "bash_config":</p>
<pre><code> - hosts: localhost
connection: local
vars:
bash_config: "{{ ansible_user_dir }}/.profile"
tasks:
- stat: path="{{ ansible_user_dir }}/.profile"
register: bash_config

Share websocket data with multiple components in Angular 2 | <p>I have 1 main component. Inside of this component i use WebSockets to receive data from the server. I receive an object with a range of fields inside it. The number of fileds can be from 0 till 10, for example. Each time i receive an object i use <code>forEach()</code> to take all fields. For each field i need to init a component, like this:</p>
<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>self.dcl.loadIntoLocation(StreamComponent, self.elementRef, 'stream');</code></pre>
</div>
</div>
</p>
<p>If a copy of a component for current field of an object already exists, i need to update it with new received data within the view. The main my problem is i don't know how to pass the data from WebSockets to created component. I can create and init it, but i never mind how to pass data to it. Any ideas ?</p> | 3 |
Animate markers | <p>I'm trying to understand how to animate markers when using <code>mapbox-gl</code>. I'm actually using the <code>Xamarin</code> binding of the 3.2.0.3 java library, so the problem might be there.</p>
<p>I'm using the examples that we can find on the GitHub page, and mainly <a href="https://github.com/mapbox/mapbox-gl-native/blob/12fa5679ac5c735d315660fb93a632c53c81b32f/platform/android/MapboxGLAndroidSDKTestApp/src/main/java/com/mapbox/mapboxsdk/testapp/AnimatedMarkerActivity.java" rel="nofollow">this</a> example. This example shows that a simple <code>ValueAnimator</code> modifying the Position of the MarkerOptions object is enough to achieve a movement.</p>
<p>All my attempts to move a marker failed: applying SetPosition on a MarkerOptions object has no effect.</p>
<p>I've tried temporary solutions, like removing all the markers and re-add them. Either in an animator or by making my own logic in the Update event. But of course, markers are flickering because modifications to the map are not perfectly sync'ed with the thread UI.</p>
<p>When reading the <code>mapbox-gl</code> source-code samples on the project page, it seems clear to me that using <code>Animator</code> on MarkerOptions is a good practice, but it just seems to fail no matter what I'm trying to do.</p>
<p>Summary: Invoking <code>_myMarkerOptions.SetPosition(new LatLng(10, 10));</code> on an existing marker just has no effect.</p> | 3 |

<p>I don't really understand if that try should be the first thing in the file (but I tried both version and I have the same result).
What am I missing here?</p>
<p>I looked over <a href="https://stackoverflow.com/questions/29225200/ocaml-unbound-module-core-with-ocamlinit-setup">this question</a>, but my situation isn't like that (I don't get all those errors, only the Unbound module one). </p> | 3 |

TCL; saving multiple list with foreach command | <p>I do the following :</p>
<pre><code>set q [list Phi1 Phi2 Phi3 Phi4 Phi5 Phi6 Phi7 Phi8 Phi9 Phi10 Phi11 Phi12 Phi13 Phi14 Phi15 Phi16 Phi17 Phi18 Phi19 Phi20 Phi21 Phi22 Phi23 Phi24 Phi25 Phi26 Phi27]
</code></pre>
<p>then I define my lists (from Phi1 to Phi27)</p>
<pre><code>foreach l $q {
for {set i 5} {$i<17} {incr i 1} {
set fx1 [nodeEigenvector $i 1 1]
set fy1 [nodeEigenvector $i 1 2]
set frot1 [nodeEigenvector $i 1 3]
lappend $l [list $fx1]
lappend $l [list $fy1]
lappend $l [list $frot1]
}
}

<p>Then I want to save those vector into a single file :</p>
<pre><code>foreach aer $q {
for {set re 1} {$re<27} {incr re 1} {
set Mode $aer
set fo [open Modd.out a]
puts $fo [list get $Mode]
puts [list get $aer]
close $fo
}
}
</code></pre>
<p>This doesn't work. I get a file with a list of "get Phi1" (27 times...) to Phi27...
funny fact, when I type the command <code>puts [list get $Phi1]</code> I do obtain my data as expected at screen. Anyone could help me?
If there is a simpler way to do it I'd like to know too !
(I am simply trying to build, populate, then save a matrix (27 vector)).</p> | 3 |

ServiceStack "Customizable Fields" | <p>We've been using SS Customizable Fields ("fields=" on the query string) and I think we may be missing a configuration somewhere. For us, it seems that the field names are case-sensitive - if they don't match the DTO, they're not returned. However, this is not true for the example that's linked from the AutoQuery GitHub page (changing the casing still results in the correct fields coming back):</p>
<p><a href="http://github.servicestack.net/repos.json?fields=Name,Homepage,Language,Updated_At" rel="nofollow">github.servicestack.net/repos.json?fields=Name,Homepage,Language,Updated_At</a></p>
<p>What are we missing?</p>
<p>Thanks!</p>
<p>Here's a sample that exhibits the behavior we're seeing:</p>
<p>AppHost:</p>
<pre><code>using System.Configuration;
using ServiceStack;
using ServiceStack.Data;
using ServiceStack.OrmLite;
using ServiceStack.Text;
namespace TestSS.Service {
public class AppHost : AppHostBase {
public AppHost()
: base("TestSS Service", typeof(AppHost).Assembly) {
}
public override void Configure(Funq.Container container) {
Plugins.Add(new AutoQueryFeature { EnableUntypedQueries = false });
Plugins.Add(new CorsFeature());
PreRequestFilters.Add((httpReq, httpRes) => {
if (httpReq.Verb == "OPTIONS")
httpRes.EndRequest();
});
container.Register<IDbConnectionFactory>(
new OrmLiteConnectionFactory(ConfigurationManager.ConnectionStrings["TestSS"].ConnectionString, SqlServerDialect.Provider));
JsConfig.DateHandler = DateHandler.ISO8601;
JsConfig.IncludeNullValues = true;
JsConfig.EmitCamelCaseNames = true;
}
}
}
</code></pre>
<p>DTOs:</p>
<pre><code>using ServiceStack.DataAnnotations;
namespace TestSS.DTO {
public class Employee {
[PrimaryKey]
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
[References(typeof(Department))]
public int DepartmentId { get; set; }
[Ignore]
public Department Department { get; set; }
}
public class Department {
[PrimaryKey]
public int Id { get; set; }
public string Name { get; set; }
}
}
</code></pre>
<p>Service:</p>
<pre><code>using ServiceStack;
using TestSS.DTO;
namespace TestSS.Service.Services {
[Route("/employees/{Id}", "GET")]
public class SingleEmployeeRequest : QueryBase<Employee> {
public string Id { get; set; }
}
[Route("/employees", "GET")]
public class FindEmployeesRequest : QueryBase<Employee>, IJoin<Employee, Department> {
}
}
</code></pre>
<p>Try the following routes:</p>
<pre><code>/employees?fields=FirstName,LastName <-- works
/employees?fields=firstname,LastName <-- Only LastName returned
/employees?fields=firstname,lastname <-- All properties returned ?
</code></pre>
<p>Now, remove the <strong>IJoin</strong> from the FindEmployeesRequest in the Employee service and try the routes again.</p>
<pre><code>/employees?fields=FirstName,LastName <-- works
/employees?fields=firstname,LastName <-- works
/employees?fields=firstname,lastname <-- works
</code></pre>
<p>UPDATE:</p>
<p>The casing issue is fixed with 4.0.55 but there seems to be one more odd behavior with this route:</p>
<pre><code>/employees?fields=departmentid
</code></pre>
<p>The response contains both the DepartmentId <strong>AND</strong> Id properties and the ID values are actually the <strong>DepartmentId</strong> values. The same is true for this route:</p>
<pre><code>/employees?fields=id,departmentid
</code></pre> | 3 |

<p>Everything works perfectly but I am using my own icons and I gave them id <strong>leftIcon</strong> and <strong>rightIcon</strong>.</p>
<p>The question is , how I could use jQuery or bootstrap classes to swap images using my own icons not bootstrap icons.</p>
<p>Thanks</p> | 3 |
Pegex grammar design | <p>Need parse text like the following:</p>
<pre><code>optional free text
@somemacro1( optional free text
@somemacro2(SOME TEXT)@ or other optional free text
)@
another free text
</code></pre>
<p>e.g. it is basically very simple:</p>
<ul>
<li>the source is an free text</li>
<li>which could contain some macros in a form <code>@MACRONAME(</code> <em>some content</em> <code>)@</code></li>
<li>the <em>some content</em> is again an free text which could contain some macro - e.g. the macros could be nested (see the above example)</li>
<li>the result of the parsed macro is some string (based on the macro name)</li>
</ul>
<p>I want learn <a href="https://metacpan.org/pod/distribution/Pegex/lib/Pegex.pod" rel="nofollow">Pegex</a> so decided to use it for this task.</p>
<p><strong>The question is: could someone help me with the Pegex-grammar for the above?</strong></p>
<p>Is someone wondering what i already tried, here is my test source - isn't working. :(</p>

When I refresh page, you can see a transition action? | <p>I have a little dilemma here. When I refresh the page in chrome I can see a transition action made by transition-duration on images and on the button on the bottom of the web page. The weird thing is that it does not happening on Firefox.On Mozilla it works without transition when you refresh the page. It works well only when you hover it. How can I fix it for chrome???</p>

Blank page when served from subfolder in production | <p>after creating the project successfully in local i run </p>
<pre><code>ember build --environment=production
</code></pre>
<p>it shows the following message</p>
<pre><code>Build successful - 1766ms.

<p>I copied all the files inside dist folder to a sub folder in my server
the default route index.php works but no other routes are working. Do i
need to copy any other folder to server ?</p> | 3 |
addressing `data` in `geom_line` of ggplot | <p>I am building a barplot with a line connecting two bars in order to show that asterisk refers to the difference between them:</p>
<p><a href="https://i.stack.imgur.com/WSNbf.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/WSNbf.png" alt="sample plot"></a></p>
<p>Most of the plot is built correctly with the following code:</p>
<pre><code>mytbl <- data.frame(
"var" =c("test", "control"),
"mean1" =c(0.019, 0.022),
"sderr"= c(0.001, 0.002)
);
mytbl$var <- relevel(mytbl$var, "test"); # without this will be sorted alphabetically (i.e. 'control', then 'test')
p <-
ggplot(mytbl, aes(x=var, y=mean1)) +
geom_bar(position=position_dodge(), stat="identity") +
geom_errorbar(aes(ymin=mean1-sderr, ymax=mean1+sderr), width=.2)+
scale_y_continuous(labels=percent, expand=c(0,0), limits=c(NA, 1.3*max(mytbl$mean1+mytbl$sderr))) +
geom_text(mapping=aes(x=1.5, y= max(mean1+sderr)+0.005), label='*', size=10)
p
</code></pre>
<p>The only thing missing is the line itself. In my very old code, it was supposedly working with the following:</p>
<pre><code>p +
geom_line(
mapping=aes(x=c(1,1,2,2),
y=c(mean1[1]+sderr[1]+0.001,
max(mean1+sderr) +0.004,
max(mean1+sderr) +0.004,
mean1[2]+sderr[2]+0.001)
)
)
</code></pre>
<p>But when I run this code now, I get an error: <code>Error: Aesthetics must be either length 1 or the same as the data (2): x, y</code>. By trying different things, I came to an awkward workaround: I add <code>data=rbind(mytbl,mytbl),</code> before <code>mapping</code> but I don't understand what really happens here.</p>
<p>P.S. additional little question (I know, I should ask in a separate SO post, sorry for that) - why in <code>scale_y_continuous(..., limits())</code> I can't address data by columns and have to call <code>mytbl$</code> explicitly?</p> | 3 |
