Array Definition Modelling in MongoAlchemy | <p>I try to model my MongoAlchemy class in Flask. Here is my model:</p>
<pre><code>{
"_id" : ObjectId("adfafdasfafag24t24t"),
"name" : "sth."
"surname" : "sth."
"address" : [
{
"city" : "Dublin"
"country" : "Ireland"
}
]
}
</code></pre>
<p>Here is my documents.py class:</p>
<pre><code> class Language_School(db.Document):
name = db.StringField()
surname = db.StringField()
address = db.???
</code></pre>
<p>How can I define this like array model (address) in Flask?</p>
<p><strong>Edit:</strong> I have already tried to my models like before asking question. But I took error like "AttributeError
AttributeError: 'list' object has no attribute 'items'".</p>
<pre><code>class Address(db.Document):
city = db.StringField()
country = db.StringField()
class Language_School(db.Document):
name = db.StringField()
surname = db.StringField()
address = db.DocumentField(Address)

Two ng-clicks on in same div | <p>So I've been looking around for an answer for this but I just couldn't find the answer. So what I have is a ng-repeat of items that are in a particular class="list-items". When I click on each of the item in items, it should execute a function. Within each list I have an remove button which I would like to remove the item when clicked.</p>
<p>So some code for reference:</p>
<pre><code> <div ng-click="executeCallback($index)" class="list-items">
<div class="item-info">
<span>some info here</span>
</div>
<button ng-click="removeItem($index)">X</button>
</div>
</code></pre>
<p>So I did right now, in my CSS, i tried using an position absolute on the button and a z-index of like 10000 to show that it is greater than, but when I click the removeItem button, it still calls the executeCallback function. I don't want it to call the executeCallback function.</p>
<p>Is there a way to have the removeItem function be called only when the remove button is clicked and not the parent class?</p> | 2 |
Firebase snapshot.val() not binding to $scope | <p>I'm using FireBase and trying to do some queries, the results are logging in but are not visible in the HTML <code>$scope</code>. </p>
<pre><code>var shopRef = firebaseDataService.intro;
$scope.shops = [];
var taskRef = shopRef.orderByChild("cat").equalTo("Accomodation");
taskRef.on("value", function(snapshot) {
var snapData = snapshot.val();
console.log(snapData);
$scope.shops.push(snapData);
});
</code></pre>
<p>When I use <code>$scope.$apply()</code>, I manage to get the data updated to shops, but it's still not passing anything to my directive .</p>
<pre><code> <search-card shops="shops"> </search-card>
<p> Shops are {{shops}}</p>
</code></pre>
<p>I got it working somehow with $firebaseArray </p>
<pre><code> $scope.shops = $firebaseArray(taskRef);
</code></pre>
<p>but I`d still like to know what I'm doing wrong and why it's not working with the snapshot.</p> | 2 |
How to use react inside a polymer component? | <p>It seems it could posible to use react inside a polymer web component but I couldn’t find a working example, only <a href="http://codepen.io/mcondon/pen/HKtBq" rel="nofollow">this</a>, but it seems outdated.</p>
<p><strong>HTML</strong></p>
<pre><code><link rel="import" href="http://www.polymer-project.org/components/polymer/polymer.html" />
<polymer-element name="my-polymer" constructor="" attributes="name">
<template>
<P>I AM {{name}}</P>
<div id="reactContainer"></div>
</template>
<script type="text/jsx">
/** @jsx React.DOM **/
Polymer('my-polymer', {
created: function(){},
ready: function(){},
attached: function(){},
domReady: function(){
React.renderComponent(<MyReact name="REACT INSIDE POLYMER"/>, this.$.reactContainer);
},
detached: function(){},
attributeChanged: function(attrName, oldVal, newVal) {}
});
</script>
</polymer-element>
<my-polymer name="POLYMER"></my-polymer>
</code></pre>
<p><strong>JS</strong></p>

var MyReact = React.createClass({
render: function() {
return (
<p>I AM {this.props.name}</p>
);

Bitmap Rotate And Save Image | <p>I would like to rotate and save the rotated image and move it elsewhere within my android device.</p>
<ol>
<li>I am able to rotate my image and set it to image view.</li>
<li>I can copy an UN-ROTATED image to a destination of my choice.</li>
</ol>
<p>The only thing I am unable to do is get the saved rotated image FILE (rotated.jpg)</p>
<p>My code below to rotate: (this does not save rotated file to storage?)</p>
<pre><code> Bitmap bmp = BitmapFactory.decodeFile(filePathLocal);
Matrix matrix = new Matrix();
matrix.postRotate(getImageOrientation(filePathLocal));
rotatedBitmap = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(), bmp.getHeight(), matrix, true);
//Set Image
ImageButton ibProfile = (ImageButton) findViewById(R.id.ibProfile);
ibProfile.setImageBitmap(rotatedBitmap);
</code></pre>
<p>Now the above only rotates temporarily until the activity is ended, now I would like to save this rotated image from above code and move it somehwere before uploading it to server, I already know how to copy/move files and upload so no need to post those codes - all I need is the code for SAVING ROTATED IMAGE, so that I have something like /sdcard/saved_rotated_image.jpg</p> | 2 |
Google geocoder API: Lookup partial postal code (Germany) | <p>I am trying to build an autocomplete where people can start typing a postal code, and get meaningful suggestions before the postal code is complete.</p>
<h3>Existing example</h3>
<p>An existing example can be found here: <a href="https://weisse-liste.de/de/arzt/arztsuche/" rel="nofollow">https://weisse-liste.de/de/arzt/arztsuche/</a></p>
<p>Typing "120" in "Ort oder Postleitzahl" gets a list of suggestions where the postal code starts with "120". I am not affiliated with this site, and don't know if they are even using the Google geocoding API. (The request goes to their own server, then they do something with it.)</p>
<h3>Attempt with Google geocoding API</h3>
<p>The closest I can get with Google API is <a href="http://maps.googleapis.com/maps/api/geocode/json?address=120&sensor=false&components=country:DE" rel="nofollow">http://maps.googleapis.com/maps/api/geocode/json?address=120&sensor=false&components=country:DE</a></p>
<p>But the only result this gives me is the one with "formatted_address" : "Germany", so the entire country.</p>
<h3>EDIT: client-side js vs server-side php / handcrafted request url</h3>
<p>The existing answer proposes client-side javascript. Which is totally valid given the question.</p>
<p>It would still be interesting to see an answer giving a hand-crafted url similar to the one above, which can be used in a server-side request. If this is not possible, no problem. An advantage could be privacy of the visitor, by avoiding a client-side request to Google. I am not even saying this is a good idea, but it could still be useful information.</p> | 2 |

CAShapeLayer path spring animation not 'overshooting' | <p>I'm experimenting with animating CAShapeLayer paths with CASpringAnimation. The expected result is a 'morphing' between shapes that acts 'springy'.</p>
<p>I have a basic code example between a circle and square path as below, however the end result is a spring animation that does not 'overshoot' past the final, larger square path, which is the expected behaviour.</p>
<p><a href="https://i.stack.imgur.com/NTDGp.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/NTDGp.gif" alt="enter image description here"></a></p>
<p>My code is:</p>
<pre><code>let springAnimation = CASpringAnimation(keyPath: "path")
springAnimation.damping = 1
springAnimation.duration = springAnimation.settlingDuration
springAnimation.fromValue = standardCirclePath().cgPath
springAnimation.toValue = standardSquarePath().cgPath
circleLayer.add(springAnimation, forKey: nil) // Where circleLayer (red background) is a sublayer of a basic UIView in the frame (blue background)
</code></pre>
<p>I got my paths <a href="https://stackoverflow.com/questions/24788283/ios-animate-morph-shape-from-circle-to-square">from this answer</a>.</p>
<p>Is there a way with CASpringAnimation to achieve this for a CAShapeLayer path transform? Otherwise, what are the alternatives?</p> | 2 |

action attached to selector in bootstrap table will not fire on page change | <p>This is an issue I have with Wenzhixin's Bootstrap table.</p>
<p>If I have a selector (ie a link) with an action attached (eg <em>on('click', fucntion() {...});</em> ) in any of the cells, that action won't fire when page is changed, sorting is applied search is performed.</p>
<p>Here's a short example: <a href="https://jsfiddle.net/L4h0gs4g/" rel="nofollow">https://jsfiddle.net/L4h0gs4g/</a></p>
<p><strong>HTML</strong>:</p>
<pre><code><table class="table table-striped table-bordered table-hover table-condensed table-responsive"
data-show-toggle="true"
data-show-columns="true"
data-toggle="table"
data-sort-name="device"
data-sort-order="desc"
data-striped="true"
data-pagination="true"
data-search="true">
<thead>
<tr>
<th data-sortable="true" data-field="device">Device</th>
<th data-sortable="true" data-field="assettag">Asset Tag</th>
<th data-sortable="true" data-field="serial">Serial No.</th>
<th data-sortable="false">Service<br />History</th>
</tr>
</thead>
<tbody>
<tr>
<td>RICOH SPC242SF PRINTER</td>
<td>C013991</td>

<tr>
<td>RICOH SPC242SF PRINTER</td>
<td>C013991</td>
<td>T222PB01287</td>
<td class="fleet_machine_actions">
<a href="javascript:void(0);" class="machine_actions" title="Service History">check</a>
</td>
</tr>
</tbody>
</table>
</code></pre>
<p><strong>jQuery</strong>:</p>
<pre><code><script>
$(document).ready(function() {
$(".machine_actions").on('click', function(e){
alert($(this).attr("title"));
});
})
</script>
</code></pre>
<p>The link will trigger the alert box at first, but if you sort the table it will not trigger again. It's like jQuery cannot see that selector once the table's been changed / updated.</p>
<p>Is this a known bug or is there a workaround this at all?</p>
<p>Also posted on <a href="https://github.com/wenzhixin/bootstrap-table/issues/2488" rel="nofollow">https://github.com/wenzhixin/bootstrap-table/issues/2488</a></p> | 2 |
Ruby subclass not inheriting parent method or not able to call parent methods in class body | <p>I'm making a page-object.</p>
<pre><code>require 'watir-webdriver'
class Page
attr_accessor :driver
def initialize
@driver = Watir::Browser.new :phantomjs
@driver.goto(some_arbitrary_url)
end
def element(**attrs)
@driver.element( id: attrs[:id], tag_name: attrs[:tag_name])
end
def elements(**attrs)
@driver.elements( class: attrs[:class], tag_name: attrs[:tag_name])
end
end
</code></pre>
<p>However when I subclass the <code>Page</code> class, I cannot use it's <code>element</code> methods in the class body, unless I put them in a method, like so:</p>
<pre><code>class Home < Page
#throws NoMethodError: undefined method 'element' for Home:Class
some_element = element(id: 'elements_id')
#works
def some_arbitrary_element
element(id: 'elements_id')
end
end
</code></pre>
<p>So far, just tinkering, I've tried doing <code>protected: element, elements</code> as well as <code>self.element(...)</code> both to no avail. So what's going on? I'm not reading anything enlightening in Matz' Ruby book about method inheritance, and usually Ruby is so unsurprising, so it's hard for me to identify where the problem actually is.</p> | 2 |

Does single hive application(job) spawn multiple yarn applications? | <p>Does a single HIVE query that gets submitted to Yarn creates multiple jobs (i.e. multiple YARN applications) ? Here I treat job and application to be the same think in YARN context.</p>
<p>From what I understand -- Yarn creates an Application Master (AM) per 'application'. So here that single HIVE query can be treated as an 'application'. So, the Resource Manager will create container on some node and start AM in that container. That container in turn may create multiple 'tasks' (not applications) i.e. mappers and reducers within other containers reserved for that AM (on the same or different node -- this is immaterial here). Now the collection of all these Application Masters are engaged in solving that single HIVE query that is submitted to YARN. In fact that's why we say that AM is per application. Since we submitted just one HIVE query, from YARN point of view there is only one application. So when I fire the below YARN command, it should show me just one application running:-</p>
<pre><code>yarn application -list
</code></pre>
<p>Is this understanding correct? Or that if we have several mappers and reducers spawned for that one HIVE query, multiple YARN applications are invoked?</p> | 2 |
Pig CSVExcelStorage DoubleQuoted Commas | <p>I am receiving csv formatted files (fields are comma delimited and double-quoted) into HDFS and have developed a pig script which removes the header rows and strips the double quotes before I insert the data into Hive using an HQL script.</p>
<p>This process has been working fine; however, today I discovered a data issue with one of the tables. The files for this table in particular have a string field which can contain multiple commas within the double quotes. This is resulting in the data being incorrectly loaded into the wrong columns in Hive for some of the records.</p>
<p>I cannot change the format of the files at the source.</p>
<p>Currently I am using the PiggyBank CSVExcelStorage to process the csv formatting as follows. Can this be modified to produce the correct result? What other options do I have? I noticed that there is also a CSVLoader now but havent found any examples showing how to use/implement it. <a href="https://pig.apache.org/docs/r0.8.1/api/org/apache/pig/piggybank/storage/CSVLoader.html" rel="nofollow">Pig CSVLoader</a></p>

How can I initialize a list and append objects of any type to it in Python | <p>I am trying to write a Python program that will initialize a list and add objects of any type to the list. I believe that I have initialized the list properly in my <code>__init__</code> method, but I cannot seem to pass any objects to it using the <code>.join()</code> method. I chose the <code>.join()</code> method because the <code>.append()</code> doesn't seem to handle object type <code>str</code>. </p>
<pre><code>class Bag(object):
'''This is where the docstring goes.'''
def __init__(self):
self.contents = []
def put_in_bag(self, contents):
contents.join(contents)
def __str__(self):
return "The bag has: " + str(self.contents)
if __name__ == "__main__":
bag1 = Bag()
bag1.put_in_bag("comb")
bag1.put_in_bag("candy bar")
print bag1
</code></pre>
<p>I receive the following output:</p>
<p><code>The bag has: []</code></p>
<p>This is homework for a college course and I am an inexperienced Python programmer. It seems like it should be pretty straight forward, but I am obviously missing something.</p> | 2 |
Oracle APEX Shuttle Refresh to Display Shuttle Right Values in Session State | <p>I'm using Oracle APEX v4.2 with Oracle 11g R2 DB and IE11 browser.</p>
<p>I have a shuttle item within my page called <code>P1_MY_SHUTTLE</code> that has some values on the left based on a LOV query, which is all good.</p>
<p>What I also have is the ability to let the user enter their value from a separate text field <code>(P1_MY_VALUE)</code> with an "Add" button next to it.</p>
<p>So when the user enters their value and presses the "Add" button, I want this value to be added to the shuttle (right side).</p>
<p>I have a Dynamic Action click happening with the "Add" button that runs the following <code>PL/SQL</code> code:</p>
<pre><code> begin
if :P1_MY_VALUE is null then
:P1_MY_SHUTTLE := :P1_MY_VALUE;
else
:P1_MY_SHUTTLE := :P1_MY_SHUTTLE || ':' || :P1_MY_VALUE;
end if;
end;
</code></pre>
<p>Now, this all works fine as I have the values in session state but my problem is, I need to show these values within my <code>P1_MY_SHUTTLE</code> to the user each time they press the "Add" button.</p>
<p>Unfortunately I can't refresh the shuttle item using a DA Refresh as this doesn't work but if I perform a full page refresh (F5), the results in session are then displayed.</p>
<p>How can I show the results without performing a full page refresh? I basically need to show the values in session state after each click of the "Add" button.</p> | 2 |

Custom index comparator in MongoDB | <p>I'm working with a dataset composed by probabilistic encrypted elements indistinguishable from random samples.

<pre><code>F(h,l,r) = ( SHA256(l | r) + h ) % 3

<p>where the operator | is a standard concatenation function.</p>
<p>I want to execute the following query <strong>in an efficient way</strong>, such as in a collection with some suitable indexing: </p>
<pre><code>db.c.find( { F(h,l,r) :{ $eq: 0 } } )

How to show more details in `seaborn.kdeplot()`? | <p>I have a scatter plot on the left-hand side below, where there are lots of data points, and the figure on the right are corresponding density plot using <code>seaborn.kdeplot()</code>. But unfortunately since the variance of the density is so large that <code>kdeplot</code> fails to capture many details in other low-density area (e.g. there is basically no information about the density distribution on the top right). </p>

How to scrape multiple pages of search results using R | <p>I'd like to scrape a website which lists all the qualifications in South Africa (<a href="http://allqs.saqa.org.za/search.php" rel="nofollow">http://allqs.saqa.org.za/search.php</a>)</p>
<p>When you first go to the link you will note that its a page with search criteria. I want to scrape all the results so I don't enter anything in the search criteria - just click "GO" which then returns the search results which I want to scrape. The results are displayed for 20 records and there are 16521 pages of results. At this stage the URL is still as above.</p>
<p>Is it possible to scrape these results? From the online searching I've been doing I've found solutions to where you the page results search criteria are defined in the URL. However for the site I want to scrape this is not option</p>
<p>Ideally I'd like to use R to do the scraping, however I'm open to other suggestions if its not possible in R</p>
<p>Many thanks

Model persistence in Scikit-Learn? | <p>I am trying to save and load scikit-learn model but facing issues when the save and load are happening on different python versions.
Here what I have tried:</p>
<ol>
<li><p>Using pickle to save a model in python3 and deserialize in python2.This works for some of the models like LR,SVM but it fails for KNN.</p>
<pre><code>>>> pickle.load(open("inPy3.pkl", 'rb')) #KNN model
ValueError: non-string names in Numpy dtype unpickling
</code></pre></li>
<li><p>Also , I tried to serialize and deserialize in json using jsonpickle but getting the following error.</p>
<pre><code>data = jsonpickle.encode(lr) #lr = logisticRegression Model
jsonpickle.decode(data)
AttributeError: 'dict' object has no attribute '__name__'
</code></pre></li>
</ol>
<p>Also, I want to know if there is some utility which I can use to serialize and deserialize scikit-learn model objects to human readable format (json,xml,protobuf etc).</p> | 2 |

WordPress: Move inline JS to be fired after deffered jQuery | <p>Trying to follow Google Page Insights suggestions, I've got the "JS render block" recommendation for and it is related to <code>jQuery</code> main file.</p>
<p>My site use WordPress with some plugins. One of the plugins throw its JS inline. So when I move <code>jQuery</code> to load in the footer, or when I use "defer" mode to load it, I get <code>jQuery is not defined</code> once the inline code fired.</p>
<p>I was trying to find a global solution to 'catch' all inline scripts and delay it after <code>jQuery</code> main file is executed at the end of the document.</p>
<p>I wrote a solution that works great for me. It is very straight forward solution for my specific situation, but I failed to make this as a filter for <code>the_content</code> or widget output. I would like to make this a global solution, so I wouldn't need to worry about any JS firing somewhere.</p>
<p>Any ideas how to make it work? Here my code so far, for this specific case, which runs through a shortcode:</p>
<pre><code>/* Get shortcode HTML */
$widget_shortcode = do_shortcode($shortcode);
/* Take out all scripts into an array */
$delayed_scripts = array();
preg_match_all('#<script(.*?)</script>#is', $widget_shortcode, $match);
foreach ($match as $val){
$delayed_script = '<script '.$val[0].'</script>';
array_push($delayed_scripts, $delayed_script);
}
/* Remove all scripts from HTML */
$widget_shortcode = preg_replace('#<script(.*?)</script>#is', '', $widget_shortcode);
/* Echo filtered HTML */
echo $widget_shortcode;
</code></pre>
<p>And just before the closing <code></body></code> tag:</p>
<pre><code>foreach ($delayed_scripts as $script) {
echo $delayed_script;
}

adjusting tableView height while using self sizing cells and a non scrollable table | <p>The problem I have is that I am using self-sizing cells, and estimated row height. </p>
<p>My tableview is a non scrollable table in a scrollview. I have a variable for the table height which I initially set to 0. </p>
<p>I am trying to update my tables height to be the right size depending on how many cells will fill it and depending on the size those cells will take up. I am trying to use <code>tableview.contentSize.height</code> to get the tables height and set the variable to that size. </p>
<p>I then recall my alignment function to reset the tables height. When I build and run the tables size isn't big enough to show all of the cells that it should. </p>

Reducing CPU usage of navigator.webkitGetUserMedia (Electron: DesktopCapturer) | <p>I'm using <code>navigator.webkitGetUserMedia</code> to capture screenshot of a window once every second by assigning the returned <code>stream</code> to a <code><video></code> and copying it to a <code><canvas></code> and saving the Buffer to file.</p>
<p>The CPU usage in my application is consistently high and I've pinpointed it to this area.</p>
<h1>Code</h1>
<pre><code>// Initialize the video, canvas, and ctx
var localStream,
_video = document.querySelector('#video'),
_canvas = document.querySelector('#canvas'),
_ctx = _canvas.getContext('2d'),
sourceName = 'my-window-id';
// Load the stream from navigator.webkitGetUserMedia
navigator.webkitGetUserMedia({
audio: false,
video: {
mandatory: {
chromeMediaSource: 'desktop',
chromeMediaSourceId: sourceName,
minWidth: 1920,
maxWidth: 1920,
minHeight: 1080,
maxHeight: 1080
}
}
}, gotStream, getUserMediaError);
function gotStream(stream) {
// Use the stream in our <video>
_video.src = window.URL.createObjectURL(stream);
// Reference the stream locally
localStream = stream;
}
function captureState() {
var buffer,
dataURL;
// Draw <video> to <canvas> and convert to buffer (image data)
_ctx.drawImage(_video, 0, 0);
dataURL = _canvas.toDataURL('image/png');
buffer = new Buffer(dataURL.split(",")[1], 'base64');
// Create an image from the data
fs.writeFileSync('screenshot.png', buffer);
}
// Capture state every second
setInterval(function() {
captureState();
}, 1000);
</code></pre>
<p>This code my not run, it's a simplified version of what I have in my code to make it StackOverflow readable.</p>
<h1>Things I've Tried</h1>
<ol>
<li><code>_video.pause()</code> and <code>_video.play()</code> when needed. Didn't seem to change CPU usage.</li>
<li><code>_video.stop()</code>. This means I would have to get the stream again which causes a spike in CPU usage worse than keeping it open.</li>
</ol>
<p>My best lead right now is to change the frame rate by adding:</p>
<pre><code> optional: [
{ minFrameRate: 1 },
{ frameRate: 1 }
]
</code></pre>
<p>Extremely low frame rate would be fine. However, I haven't been able to determine if the <code>frameRate</code> setting works in this case. <a href="https://developer.mozilla.org/en/docs/Web/API/Navigator/getUserMedia" rel="nofollow noreferrer">The docs</a> don't have it listed and I don't have the newer <code>mediaDevices.getUserMedia</code> available.</p>
<p>Is it possible to set extremely low frame rates (or any at all) for <code>navigator.webkitGetUserMedia</code>?</p>
<p>Has anyone been able to reduce CPU usage of the stream in any other way?</p>
<p>Any alternative methods of achieving the same goal (state capture on interval) would also be helpful.</p>
<p>Thanks!</p>
<p><strong>Side Note</strong></p>
<p>This is in an Electron app on Windows using <a href="https://github.com/electron/electron/blob/master/docs/api/desktop-capturer.md" rel="nofollow noreferrer">DesktopCapturer</a> to get the <code>chromeMediaSourceId</code>.</p>
<hr />
<p><strong>Update on CPU Usage</strong></p>
<ol>
<li>Cost of running <code>stream</code>: 6% CPU Usage</li>
<li>Calling <code>captureState</code> every 1000ms: 5% CPU Usage</li>
</ol>
<p>Total Current: 11%</p>
<p>Currently working on reducing #2 based on the recommendations of Csaba Toth so far. I should be able to reduce <code>captureState</code> by changing how the canvas is captured. Will update when that's done.</p>
<p>For #1, if I can't avoid capturing the video stream I'll have to just try to cap the total CPU usage at just over 6% by optimizing #2.</p> | 2 |
gstreamer and QML: Drawing on a QML Window | <p>I have been trying to draw a gstreamer camera output onto a QML object for months now. At least on my ARM system none of the qt-gstreamer qml components really worked with the camera output (I can show the test video source) but never anything from the camera.</p>
<p>So, I went to the old school of rendering onto a regular qt window with the following example:</p>
<pre><code>#include <glib.h>
#include <gst/gst.h>
#include <gst/video/videooverlay.h>
#include <QApplication>
#include <QTimer>
#include <QWidget>
int main(int argc, char *argv[])
{
if (!g_thread_supported ())
g_thread_init (NULL);
gst_init (&argc, &argv);
QApplication app(argc, argv);
app.connect(&app, SIGNAL(lastWindowClosed()), &app, SLOT(quit ()));
// prepare the pipeline
GstElement *pipeline = gst_pipeline_new ("xvoverlay");
GstElement *src = gst_element_factory_make ("v4l2src", NULL);
GstElement *sink = gst_element_factory_make ("xvimagesink", NULL);
gst_bin_add_many (GST_BIN (pipeline), src, sink, NULL);
gst_element_link (src, sink);
// prepare the ui
QWidget window;
window.resize(320, 240);
window.show();
WId xwinid = window.winId();
gst_video_overlay_set_window_handle (GST_VIDEO_OVERLAY (sink), xwinid);
// run the pipeline
GstStateChangeReturn sret = gst_element_set_state (pipeline,
GST_STATE_PLAYING);
if (sret == GST_STATE_CHANGE_FAILURE) {
gst_element_set_state (pipeline, GST_STATE_NULL);
gst_object_unref (pipeline);
// Exit application
QTimer::singleShot(0, QApplication::activeWindow(), SLOT(quit()));
}
int ret = app.exec();
window.hide();
gst_element_set_state (pipeline, GST_STATE_NULL);
gst_object_unref (pipeline);
return ret;
}
</code></pre>
<p>Here I am window ID of the QWidget and overlaying the video in it. This is the only thing that ever worked for me.</p>
<p>However, now I wonder, if it is possible to get the window ID of an underlying qt graphical element. So, for example if I have something like:</p>
<pre><code>ApplicationWindow {
id: rootWindow
objectName: "window"
visible: true
width: 800
height: 480
color: "#FFFFFF"
Rectangle {
width: 100
height: 100
color: "red"
border.color: "black"
border.width: 5
radius: 10
}
}
</code></pre>
<p>Is it possible to get the ID of the underlying graphical window object or does that not exist? is there some component which has its own graphical ID that I can use in QML and then query from my C++ app and use it to overlay the video?</p> | 2 |

How to make Windows Services state to "Manual"? | <p>I'm stopping a windows service currently from my code as shown below:</p>
<pre><code>srvc_status = ControlService(serviceHandle, SERVICE_CONTROL_STOP, (LPSERVICE_STATUS)&status);
</code></pre>
<p>But it is changing the state of service to <strong>Automatic (Delayed Start)</strong>. But I need it to be set to <strong>Manual</strong>. I went through the windows documentation also regarding <strong>ChangeServiceConfig</strong> and didn't found anything which says about the options to explicitly set the state to <strong>Manual</strong>.
Can anyone guide me here towards the correct API call ?</p> | 2 |

<p>Do I need to add onchange() function to the dropdown above?</p> | 2 |
Change url of categories | <p>I created a page listing the categories with this function:</p>
<pre><code>function show_categories_fn(){
return wp_list_categories("echo=0&title_li");
}
add_shortcode('show_categories', 'show_categories_fn');
</code></pre>
<p>But, when I click the category link, I find the list of posts bound to this one, but the url is <code>mysite.com/category/mycategory</code></p>
<p>Yet, I would like to have only <code>mysite.com/mycategory</code>. </p>
<p>Do you know how can it be done?</p>
<p><strong>Edit :</strong> </p>
<p>I am not sure that this answer answers my question. For my posts I want the structure the url / categoryname / postname, but when I click a category I want only the category (url of archive page), without the sub-folder category which corresponds to nothing</p> | 2 |
Struggling to make Bootstrap-select to work | <p>I'm trying to use bootstrap-select (<a href="http://silviomoreto.github.io/bootstrap-select/" rel="nofollow">http://silviomoreto.github.io/bootstrap-select/</a>) and cannot make it load any options. It renders the dropbox but not the options. I'm a little bit lost and not sure if I'm loading the proper dependencies in the proper order or doing something stupid.</p>
<p>I'm starting to learn all that stuff and might be doing something wrong in here. I've created a plunker so I can clearly reproduced the issue.</p>
<p>Appreciate any help!</p>

Shuffle songs in music player | <p>I’m just starting Android development and Java, and this is my first app to get acquainted with Android development. I’m almost done with the app, the only thing left is shuffling songs. I tried many steps to get it right, and I’ve scoured the web and SO for related question, yet I still can’t get it right.</p>
<p>This snippet of code is in my Service class, Playlist is passed from Main Activity:</p>
<pre><code>public void setPlayList(ArrayList<SongModel> playlist) {

list = new ArrayList<Integer>();
for(int i =0; i <= playList.size();i++){
list.add(i);
}
Collections.shuffle(list, new Random(System.nanoTime()));
}
</code></pre>
<p>The code below is how songs are played, this snippet is in configPlayBack() method that plays the song from the song id:</p>
<pre><code>long item = 0;
item = playList.get(MusicPref.isShuffle(this)? list.get(position): position).getSongId();
</code></pre>
<p>the snippet for playing next song is:</p>
<pre><code>public void playNext() {
position++;
if (position >= playList.size()) {
position = 0;
}
configPlayBack();
}
</code></pre>
<p>But the songs are still playing serially.</p>
<p>EDIT:</p>
<pre><code>public void configPlayBack(){
prepared = true;
player.reset();
if ( playList.size()>0){
long item = 0;
item = playList.get(MusicPref.isShuffle(this)? list.get(position):position).getSongId();

Make deeply nested JSON from data frame in R | <p>I'm looking to take a nice tidy data frame and turn it into a deeply nested JSON using R. So far I haven't been able to find any other resources that directly address this task - most seem to be trying to take it in the other direction (un-nesting a JSON). </p>
<p>Here's a small dummy version of the data frame I'm starting with. Imagine a survey was given to two audiences within a company, one for managers and a separate one for employees. The surveys have different sets of questions with different IDs but many questions overlap and I want to compare the responses between the two groups. The end goal is to make a JSON that matches up section IDs, question IDs, and option IDs/text from two surveys in the correct hierarchy. Some questions have subquestions that require a further level of nesting, which is what I’m having difficulty doing. </p>
<pre><code>library(dplyr)
library(tidyr)
library(jsonlite)
dummyDF <- data_frame(sectionId = c(rep(1,9),rep(2,3)),
questionId = c(rep(1,3),rep(2,6),rep(3,3)),
subquestionId = c(rep(NA,3),rep("2a",3),rep("2b",3),rep(NA,3)),
deptManagerQId = c(rep("m1",3),rep("m2",3),rep("m3",3),rep("m4",3)),
deptEmployeeQId = c(rep("e1",3),rep("e3",3),rep("e4",3),rep("e7",3)),
optionId = rep(c(1,2,3),4),
text = rep(c("yes","neutral","no"),4))
</code></pre>
<p>And here’s the end result I’m trying to achieve:</p>
<pre><code>theGoal <- fromJSON('{
"sections": [
{
"sectionId": "1",
"questions": [
{
"questionId": "1",
"deptManagerQId": "m1",

<p>Here are a few approaches I’ve tried using nest from tidyr that end up either only getting me part of the way there or throwing an error message.</p>
<h1>1</h1>
<pre><code>list1 <- dummyDF %>% nest(-sectionId, .key=questions) %>%
mutate(questions = lapply(seq_along(.$questions), function(x) nest(.$questions[[x]], optionId, text, .key = options))) %>%
list(sections = .)
</code></pre>
<h1>2</h1>
<pre><code>nested1 <- dummyDF %>% nest(-sectionId, .key=questions) %>%
mutate(questions = lapply(seq_along(.$questions), function(x) nest(.$questions[[x]], optionId, text, .key = options)))
nested2 <- nested1 %>% mutate(questions = lapply(seq_along(.$questions), function(x) nest(.$questions[[x]], subquestionId, .key = subquestions)))
#Gives this error: cannot group column options, of class 'list'
</code></pre>
<h1>3</h1>
<pre><code>list2 <- dummyDF %>% nest(-sectionId, .key=questions) %>%
mutate(questions = lapply(seq_along(.$questions),
function(x) {ifelse(is.na(.$questions[[x]]$subquestionId),
function(x) {.$questions[[x]] %>% select(-subquestionId) %>% nest(optionId, text, .key = options)},
function(x) {.$questions[[x]] %>% nest(subquestion_id, .key = subquestions)})})) %>%
list(sections = .)
#Gives this error: attempt to replicate an object of type 'closure'
</code></pre>
<p>Any ideas would be greatly appreciated. I’m open to any approaches. I took the issue to a local R user group meet-up but wasn’t able to come up with any solutions so I’ve got my fingers crossed here. I realize R might not be the best tool to accomplish this but it’s the one I know so I’m giving it a shot. Thanks.</p> | 2 |

Change only the label text in Google gantt chart | <p>I'm using Google's gantt chart and I wish to change the text of the label only (Not the the tooltip). For example, one of the labels says "This is a very long label to test the width of the label on a google gantt chart" and I wish it to say on the label "This is a very ...". On the tooltip, I would like it to display the full text. </p>
<p>If I make the change in when adding the row</p>
<pre><code>data.addRows([
['Research', 'This is a very long label to test the width of the label on a google gantt chart'
</code></pre>
<p>It changes both the label and the tooltip. I would just like it to change the label. Please see the <a href="https://jsfiddle.net/ccakn5870/ntectnth/" rel="nofollow noreferrer">jfiddle</a> and the image below. How can this be done?</p>

Gensim Doc2Vec - Pass corpus sentences to Doc2Vec function | <p>I used the <code>MySentences</code> class for extracting sentences from all files in a directory and use this sentences for train a <em>word2vec</em> model.
My dataset is unlabeled.</p>
<pre><code>class MySentences(object):
def __init__(self, dirname):
self.dirname = dirname
def __iter__(self):
for fname in os.listdir(self.dirname):
for line in open(os.path.join(self.dirname, fname)):
yield line.split()
sentences = MySentences('sentences')
model = gensim.models.Word2Vec(sentences)
</code></pre>
<p>Now I want to use that class to make a <em>doc2vec</em> model. I read <a href="https://radimrehurek.com/gensim/models/doc2vec.html" rel="nofollow">Doc2Vec</a> reference page. <code>Doc2Vec()</code> function gets sentences as parameter, but it doesn't accept above sentences variable and return error :</p>
<pre><code>AttributeError: 'list' object has no attribute 'words'
</code></pre>
<p>What is the problem? What is the correct type of that parameter?</p>
<p><strong>Update :</strong></p>
<p>I think, unlabeled data is the problem. It seems doc2vec needs labeled data.</p> | 2 |
Determine programmatically if we're connecting to SharePoint Online or on-premise with CSOM API | <p>I would like to know if there is a way to determine if we're about to connect to a SharePoint Online server or an on-premise one (as the Credentials object type differs). I'm using the CSOM API in C# with a SharePoint 2013 and a SharePoint Online server.</p>
<p>So far, I haven't found anything useful in the <a href="https://msdn.microsoft.com/en-us/library/office/microsoft.sharepoint.client.clientcontext_members.aspx" rel="nofollow">ClientContext</a> object itself so I'm thinking to just check the login that the user to see if it's login is like "DOMAIN\ACCOUNT" or "[email protected]" but I don't know if it's possible to have a Domain\Account login type on SharePoint Online or something else.</p>
<p>If it's impossible to do, I'll just ask the user to tell what type of server it is.</p> | 2 |
Android manifest make apk a launcher app on tablet but normal app on phone | <p>How do you make one apk be a <strong>launcher</strong> app on tablets but just a <strong>normal</strong> app on phones? How do you configure the manifest file for this?</p>
<p>By launcher app I mean it will show up as one of the option when the apk is run on tablets:
<a href="https://i.stack.imgur.com/F3UaA.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/F3UaA.png" alt="Select home picker"></a></p>
<p>If the same apk is run on phones, it will not show the "Select a home app" picker.</p>
<p>In simple terms, this is the behaviour the apk needs to have:</p>
<p><strong>Goal:</strong></p>
<ul>
<li>When I click home on <strong>phones</strong>, I should <strong>not see</strong> the app as one of the
launcher choices. </li>
<li>When I click home on <strong>tablet</strong> then I should <strong>see</strong> the
app as one of the choices.</li>
</ul>
<p>My approach is I have a ChooserActivity.java that determines what kind of device is being run. If it is a tablet it will start TabletMainActivity.java, if it is phone it will start PhoneMainActivity.java. (The code for finding out if it is a tablet or a phone is okay.)</p>
<p>ChooserActivity.java</p>
<pre><code> public class ChooserActivity extends AppCompatActivity {
ImageView tabIndicator;
private static final String TAG = "Chooser";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_chooser);
Log.d(TAG, "onCreate2() Chooser");
finish();
if (findViewById(R.id.tabIndicator)==null){
//PHONE
startActivity(new Intent(this, PhoneMainActivity.class));
}else{
//TABLET
startActivity(new Intent(this, TabletMainActivity.class));
}
}

<p>TabletMainActivity.java has the following launcher manifest settings:</p>
<pre><code><activity android:name=".TabletMainActivity" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<!-- launcher setting -->
<category android:name="android.intent.category.HOME" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
</code></pre>
<p>PhoneMainActivity.java is just a normal activity, has nothing on the manifest. This is on purpose because I want this activity to be a normal activity on phones.</p>
<pre><code><activity android:name=".PhoneActivity">
</activity>
</code></pre>
<p>My ChooserActivity.java is the first activity that gets started when the app gets clicked/opened, it then chooses between the 2.
ChooserActivity manifest entry</p>
<pre><code><activity android:name=".ChooserActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</code></pre>
<p>I tried different variations for the intent-filter for the TabletMainActivity.java but never able to get the correct behaviour. I always see the launcher picker being shown. </p> | 2 |

How to check the Support Library / AppCompat library version at Runtime? | <p>We have an SDK for Android that requires Support Library v4 with targetSdk 23 (meaning that the Support Library should be also 23). For commercial reasons, I have to upgrade the SDK so it should work even if the App is compiled against API 21. </p>
<p>This means that some calls to the Support Library should be done conditionally depending on the current Support Library version of the App (<strong>not the current API level</strong>), so I have 3 options here (ranked by best to worst): </p>
<p>1 - Check the Support Library version before the method call (This is what I have not figured out how to do, (if possible at all)).<br>
2 - Use reflection.<br>
3 - Use Try Catch blocks. </p>
<p>So for the 1st option, is it possible to check the support library version at runtime?</p> | 2 |
Add required to element if radio button is checked | <p>I have a form with radiobuttons and an input field. If any of the three top radio buttons are checked I need to add "required" to the input field.
My code:</p>
<pre><code><ng-form name="addShareholderForm">
<form name="form.addForm" class="form-validation" ng-submit=" $ctrl.addShareholder()" ng-init="$ctrl.setFormScope(this)">
<md-radio-group ng-model="data.group1" ng-required="true">
<md-radio-button value="passport" class="md-primary">Passport number</md-radio-button>
<md-radio-button value="ssn">Social security number(SSN) </md-radio-button>
<md-radio-button value="drivers-license">Drivers license number</md-radio-button>
<md-radio-button value="person-other">Other</md-radio-button>
</md-radio-group>
<input placeholder="Type number" ng-required="data.group1 == 'passport' || data.group1 == 'ssn' || data.group1 == 'drivers-license'">
<md-input-container>
<md-button type="submit" ng-disabled="!addShareholderForm.$valid" class="md-raised md-primary md-no-ink submitshareholder" aria-label="Lägg till">
<i class="material-icons done-button-fab">add_circle</i>Lägg till
</md-button>
</md-input-container>
</code></pre>
<p>
</p>
<p>However this is not working and I don't know what I'm doing wrong? The input field is not set to required.</p>
<p>EDIT: I changed the code according to suggestions below and added the ng-form and the button to the code. The button is supposed to be disabled when the form is invalid but i´t is enabled as soon as I check a radio button without filling out the input. </p> | 2 |
Get Email address of Facebook user from post comments | <p>I am trying to get email address from comments in posts of the Facebook page, but with no luck. I am requesting this URL:</p>
<pre><code>feed?fields=message,id,description,created_time,from,comments{from,email, id,created_time,message},story
</code></pre>
<p>I am using v2.6 of Graph API. Is there any way for getting the mail in single call or I need to send another request where I will call the ID of the Facebook User and then access the email address which will be bad practice if there is a lot of comments and users.</p> | 2 |

RSpec Couldn't find with 'id'= | <p>I'm writing an RSpec controller test and I've run into the following problem.</p>
<p>The relationship is such that Invoices belong to a Purchase, and a Purchase has many invoices. </p>
<p>My controller has:</p>
<pre><code>class InvoicesController < ApplicationController
def index
@invoices = Invoice.all
end
def new
@purchase = Purchase.find(params[:purchase])
@invoice = Invoice.new(:purchase_id => params[:purchase])
end
</code></pre>
<p>My factory has:</p>
<pre><code>FactoryGirl.define do
factory :invoice do |f|
sequence(:id) { |number| number }
f.purchase_id {rand(1..30)}
f.number { FFaker::String.from_regexp(/\A[A-Za-z0-9]+\z/) }
f.terms { FFaker::String.from_regexp(/\A[A-Za-z0-9\s]+\z/) }
f.currency { FFaker::String.from_regexp(/\A[A-Z]+\z/) }
f.total_due {'25000.00'}
f.current_balance {'12500.00'}
f.due_date { FFaker::Time.date }
f.notes { FFaker::HipsterIpsum.paragraph }
f.status {[:open, :paid, :canceled].sample}
purchase
end
factory :invalid_invoice, parent: :invoice do |f|
f.status nil
end
end
</code></pre>
<p>My controller spec (just the problematic part) has:</p>
<pre><code>describe "GET new" do
it "assigns a new invoice to @invoice" do
invoice = FactoryGirl.create(:invoice)
get :new
expect(assigns(:invoice)).to_not eq(invoice)
end
it "renders the :new template" do
get :new
expect(response).to render_template :new
end
end
</code></pre>
<p>In my routes I have:</p>
<pre><code>purchases GET /purchases(.:format) purchases#index
POST /purchases(.:format) purchases#create
new_purchase GET /purchases/new(.:format) purchases#new
edit_purchase GET /purchases/:id/edit(.:format) purchases#edit
purchase GET /purchases/:id(.:format) purchases#show
PATCH /purchases/:id(.:format) purchases#update
PUT /purchases/:id(.:format) purchases#update
DELETE /purchases/:id(.:format) purchases#destroy
invoices GET /invoices(.:format) invoices#index
POST /invoices(.:format) invoices#create
new_invoice GET /invoices/new(.:format) invoices#new
edit_invoice GET /invoices/:id/edit(.:format) invoices#edit
invoice GET /invoices/:id(.:format) invoices#show
PATCH /invoices/:id(.:format) invoices#update
PUT /invoices/:id(.:format) invoices#update
DELETE /invoices/:id(.:format) invoices#destroy
</code></pre>
<p>When I run the test I get this:</p>
<pre><code>1) InvoicesController GET new assigns a new invoice to @invoice

How to keep multiple select in sync onChange using jquery | <p>I'm trying to figure out how to keep in sync two or more selects. I actually created several select elements (I'm not sure if this is the most accurate approach, if there's another way I'd be grateful if someone tells me). </p>
<p>If I select <code>North America</code> in the first one, only the select with <code>id="north"</code> will show automatically and the others will remain hidden, if I change to <code>Central America</code>, the rest will change as well, showing only the select with <code>id="central"</code> and the rest hidden.</p>
<p>This is what I got so far:</p>
<pre><code><select id="continent">
<option value="1">North America</option>
<option value="2">Central America</option>
<option value="3">South America</option>
</select>
<select id="north">
<option value="1">Canada</option>
<option value="2">USA</option>
<option value="3">Mexico</option>
</select>
<select id="central">
<option value="1">Guatemala</option>
<option value="2">Costa Rica</option>
<option value="3">Nicaragua</option>
</select>
<select id="south">
<option value="1">Brazil</option>
<option value="2">Argentina</option>
<option value="3">Chile</option>
</select>
</code></pre>
<p>So far I've only got to sync two selects with same value:</p>
<pre><code>$("#continent").change(function(){
$("#north").val($("#continent").val())
});
</code></pre>
<p>However, this is far from what I need. Could anyone help me figure out the correct approach?</p>
<p>Thanks in advance! </p> | 2 |
Does extension messaging like chrome.runtime.sendMessage internally use JSON.stringify? | <blockquote>
<p>A message can contain any valid JSON object (null, boolean, number, string, array, or object)</p>
</blockquote>
<p>The chrome extension specification indicates that message passed between background and content script can be a Javascript object, which means that we can pass a Javascript object without using JSON.stringify. Does that mean Chrome internally execute JSON.stringify before sending messages? If not, is there a performance gain if I just pass Javascript object without JSONification?</p> | 2 |

Ruby 'cannot load such file --RMagick' | <p>I have a default installation of a jekyll project (created with <code>jekyll new sample</code>) and have included a plugin, <a href="https://github.com/mattvh/JekyllGalleryTag" rel="nofollow">JekyllGalleryTag</a>. </p>
<p>The plugin depends upon ImageMagick and RMagick. I have installed ImageMagick and RMagick successfully on Xubuntu 14.04 using these commands. </p>
<pre><code>sudo apt-get update
sudo apt-get install imagemagick --fix-missing
sudo apt-get install libmagickcore-dev
sudo apt-get install libmagickwand-dev
</code></pre>
<p>ImageMagick commands are functional, eg <code>convert logo.gif logo.jpg</code> works as expected.</p>
<p>I am running ruby-2.3.0 via rvm 1.27.0</p>
<pre><code>gem install rmagick
</code></pre>
<p>RMagick installs without any error messages.</p>
<p>JekyllGalleryTag needs galleries.rb put in /_plugins, which I have done. The first line of galleries.rb reads ...</p>
<pre><code>require 'RMagick'
</code></pre>
<p>The plugin requires some code in _config.yml, which looks like this...</p>
<pre><code>gallerytag:
dir: images/galleries
url: /images/galleries
thumb_width: 150
thumb_height: 150
columns: 4
</code></pre>
<p>My gallery images are located in /images/galleries/dig/</p>
<p>I created an html file with some Liquid code to display the result. Here's the code in dig.html</p>
<pre><code>---
layout: default
title: Dig In Italy
---
{% gallery dig %}
dig/current001.jpg:: A caption goes here!
{% endgallery %}
</code></pre>
<p>When I preview the site, with <code>jekyll serve</code>, I get this error message...</p>
<pre><code>Configuration file: /mnt/hgfs/proj/practice/jekyll/sample/_config.yml
Dependency Error: Yikes! It looks like you don't have /mnt/hgfs/proj/practice/jekyll/sample/_plugins/galleries.rb or one of its dependencies installed.
In order to use Jekyll as currently configured, you'll need to install this gem.

<p>I am new to ruby, jekyll, and linux generally. I have googled and read and experimented for hours searching for a fix. The summarized sequence above is a result of all that research. I have installed every suggested library. </p>
<p>Other fixes I tried and discarded were:</p>
<ul>
<li>including <code>require 'rubygems'</code> as the first line in galleries.rb (in addition to <code>require 'RMagick'</code>)</li>
<li><code>require 'rmagick'</code> instead of <code>require 'RMagick'</code></li>
<li>all 4 combinations of these require statements</li>
</ul>
<p>Additional wrinkles that may be relevant or not;</p>
<ul>
<li>Xubuntu 14.04 is running in VMware Player 7.1.2 </li>
<li>The host OS is Windows 7 Pro 64 bit. </li>
<li>My jekyll files are on the host NTFS filesystem, and I've been editing them with Notepad++ (a windows editor). The files are shared with the guest OS via VMware Player's Shared Folders option. This arrangement works fine for static sites and WordPress sites.</li>
<li>I am using the terminal in the guest OS, Xubuntu, for all command line work. The Xubuntu OS contains the AMP stack, along with rvm and ruby.</li>
<li>Though bundler is installed, I did not use it to install RMagick.</li>
</ul>
<p>How do I fix this?</p>
<p><strong>UPDATE:</strong> </p>
<p>I have verified that RMagick is working properly. I made a couple of small .rb scripts from the code on the RMagick Usage page. Two identical script sets were stored, one in the linux filesystem, and one in the NTFS filesystem. Both execute as expected without errors. This demonstrates that ruby works and can find and use RMagick, and that RMagick can find and use ImageMagick. And that the location of the files doesn't make a difference.</p>
<p>Yet file location does matter. I copied identical sample jekyll projects so there was one on the linux filesystem one on NTFS.
On linux <code>jekyll serve</code> executes but the plugin is not generating the thumbnail file version that jekyll is expecting. The build completes but with errors due to the missing thumbnail file. So the build wont complete when the files reside on NTFS, but will when the files are on linux.</p>
<p>At this point my theories are 1) weirdness caused by VMware Player file sharing (but one that does not affect ruby & gems consistently) or 2) something in the plugin code, which I don't have the skill to assess.</p>

Leaflet with GitHub Pages - not rendering | <p>I have a simple webpage into which I have embedded a basic leaflet map. When I try to publish this via my GitHub Pages website, the leaflet map won't render (everything else is fine).</p>
<p>GitHub Pages spec says it supports JS and this shouldn't be a problem as it's an API. I have tried to use a downloaded version of leaflet (.css and .js files uploaded to my gh-pages repository), but still nothing.</p>
<p>Anyone have any ideas why this isn't working? Is this what GitHub Pages means when it says that it will host "static" webpages (no APIs, no JS interactivity)?</p> | 2 |
Redux actions/reducers vs. directly setting state | <p>I'm new to Redux. I'm having trouble understanding the value of actions and reducers vs. components directly modifying the store. </p>
<p>In Redux, your React components don't change the store directly. Instead they dispatch an action -- sort of like publishing a message. Then a reducer handles the action -- sort of like a message subscriber -- and changes the state (more precisely, creates a new state) in response. </p>
<p>I feel like the pub/sub-like interaction adds layers of indirection that make it harder to understand what a component is actually doing -- why not just allow components to pass new state to the Redux store directly? Would it be a bad thing to inject something like <code>this.props.setReduxState</code> into a React component? </p>
<p>I'm starting to understand the value of why the state itself needs to be immutable (related question -- <a href="https://stackoverflow.com/questions/33424157/isnt-redux-just-glorified-global-state">Isn't Redux just glorified global state?</a>), related to checking for updates to see which component props need to be updated in response to state changes. My question is the extra action/reducer layers vs. manipulating the store directly.</p> | 2 |

<p>1 Date can have 3 time</p>
<p>The user is then able to select if he's available for any date / time</p>
<p>The problem is, since we add another table row for the times, they won't stay in date's column.</p>

Resizing JFrame to fit resized JPanel | <p>I am pretty new with JPanel and JFrame and probably not working with them the way I should. I'm trying to create Pong game and after creating JFrame and adding JPanel to it, I'm able to resize my JPanel but I don't know how to resize my JFrame to fit it. Game class extends JPanel.</p>
<p>main:</p>
<pre><code> public static void main(String[] args) throws InterruptedException {
int height = 500, width =(int) (height*1.56); //height = 500, width = 780;
JFrame frame = new JFrame("Pong");
Game game = new Game();
frame.add(game);
frame.setVisible(true);
game.setSize(width, height);
System.out.println(game.getHeight());
System.out.println(game.getWidth());
game.setBackground(Color.BLACK);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
System.out.println(frame.getHeight());
System.out.println(frame.getWidth());
}
</code></pre>
<p>output:</p>
<pre><code>500
780
39
136
</code></pre>
<p>The output should be somthing like:</p>
<pre><code>500
780
*above* 500
*above* 780
</code></pre>
<p>EDIT:</p>
<pre><code> public static void main(String[] args) throws InterruptedException {
int height = 500, width =(int) (height*1.56); //height = 500, width = 780;
JFrame frame = new JFrame("Pong");
Game game = new Game();
frame.add(game);
frame.setVisible(true);
game.setPreferredSize(new Dimension(width, height));
frame.pack();
System.out.println(game.getHeight());
System.out.println(game.getWidth());
game.setBackground(Color.BLACK);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
System.out.println(frame.getHeight());
System.out.println(frame.getWidth());
}
</code></pre>
<p>Changing the setSize to setPreferredSize and then call pack() for the JFrame fixed it all.</p> | 2 |
Clean Code Book by Robert Cecil Martin | <p>I know this has been asked before but I did not fully understand the answer nor did I feel the question was exactly the same as this one.</p>
<p>In the book Clean Code Book by Robert Cecil Martin, He suggests with regards to methods you should...</p>
<ul>
<li>Prefer to not pass any parameters</li>
<li>If you must pass paramters then pass only one.</li>
<li>An only pass more than this under rare circumstances.</li>
</ul>
<p>This has me confused...</p>
<p>So based on this which is correct?</p>
<p>this class...</p>
<pre><code> class FourNumberAdder
{
public int Num1 { get; }
public int Num2 { get; }
public int Num3 { get; }
public int Num4 { get; }
public FourNumberAdder(int n1, int n2,int n3,int n4 )
{
this.Num1 = n1;
this.Num2 = n2;
this.Num3 = n3;
this.Num4 = n4;
}
}
</code></pre>
<p>with this...</p>
<pre><code>FourNumberAdder FNA = new FourNumberAdder(1,2,3,4);
</code></pre>
<p>Or, This class...</p>
<pre><code>class FourNumberAdder
{
public int Num1 { get; set; }
public int Num2 { get; set; }
public int Num3 { get; set; }
public int Num4 { get; set; }
}
</code></pre>
<p>with this...</p>
<pre><code>public void go()
{
FourNumberAdder FNA = new FourNumberAdder();
FNA.Num1 = 1;
FNA.Num2 = 2;
FNA.Num3 = 3;
FNA.Num4 = 4;
}
</code></pre>
<p>or these 2 classes...</p>
<pre><code>class FourNumberAdder
{
public int Num1 { get; set; }
public int Num2 { get; set; }
public int Num3 { get; set; }
public int Num4 { get; set; }
public FourNumberAdder (FourNumbers fn)
{
this.Num1 = fn.Num1;
this.Num2 = fn.Num2;
this.Num3 = fn.Num3;
this.Num4 = fn.Num4;
}
}
class FourNumbers
{
public int Num1 { get; set; }
public int Num2 { get; set; }
public int Num3 { get; set; }
public int Num4 { get; set; }
}
</code></pre>
<p>with this...</p>
<pre><code>FourNumbers fn = new FourNumbers();
fn.Num1 = 1;
fn.Num2 = 2;
fn.Num3 = 3;
fn.Num4 = 4;
FourNumberAdder FNA = new FourNumberAdder(fn);
</code></pre>
<p>or something else? Please note I thought the last option would be right as it 'bundles up' the 4 parameters in to a new class, but then you end up with the same problem with that class as you have to either pass all the parameters in individually or access them directly via there properties. </p>
<p>Hope this is clear.</p> | 2 |
Breaking SOLID Principles in multiple implementation of an Interface | <p>I am facing a problem with dependency inversion in a <code>factory</code> method and it is also breaking Open Closed principle. My code looks like below codes</p>
<pre><code> public interface IWriter
{
void WriteToStorage(string data);
}
public class FileWriter : IWriter
{
public void WriteToStorage(string data)
{
//write to file
}
}
public class DBWriter : IWriter
{
public void WriteToStorage(string data)
{
//write to DB
}
}
</code></pre>
<p>Now I an using a factory class to solve the object creation. It look like below code</p>
<pre><code>public interface IFactory
{
IWriter GetType(string outputType);
}
public class Factory : IFactory
{
public IWriter GetType(string outputType)
{
IWriter writer = null;
if (outputType.Equels("db"))
{
writer = new FileWriter();
}
else if (outputType.Equels("db"))
{
writer = new DBWriter();
}
}
}
</code></pre>
<p>Now the problem is the <code>Factory</code> class is breaking <strong>Open closed principle</strong> so it also breakes <strong>Dependency Inversion Principle</strong></p>
<p>And then </p>
<pre><code>public interface ISaveDataFlow
{
void SaveData(string data, string outputType);
}
public class SaveDataFlow : ISaveDataFlow
{
private IFactory _writerFactory = null;
public SaveDataFlow(IFactory writerFactory)
{
_writerFactory = writerFactory;
}
public void SaveData(string data, string outputType)
{
IWriter writer = _writerFactory.GetType(outputType);
writer.WriteToStorage(data);
}
}
</code></pre>
<p>As the above factory class is breaking the dependency inversion I remove the <code>Factory</code> class and change the <code>SaveDataFlow</code> class like below</p>
<pre><code>public class SaveDataFlow : ISaveDataFlow
{
private IWriter _dbWriter = null;
private IWriter _fileWriter = null;
public SaveDataFlow([Dependency("DB")]IWriter dbWriter,
[Dependency("FILE")]IWriter fileWriter)
{
_dbWriter = dbWriter;
_fileWriter = fileWriter;
}
public void SaveData(string data, string outputType)
{
if (outputType.Equals("DB"))
{
_dbWriter.WriteToStorage(data);
}
else if (outputType.Equals("FILE"))
{
_fileWriter.WriteToStorage(data);
}
}
}
</code></pre>
<p>And resolved those dependencies using Unity Framework</p>
<pre><code>container.RegisterType<IWriter, DBWriter>("DB");
container.RegisterType<IWriter, FileWriter>("FILE");
</code></pre>
<p>Yet eventually I am ending up breaking <strong>Open Closed Principle</strong>.
I need a better design/solution to solve such a problem yet I must follow SOLID Principles.</p> | 2 |

What triggers Azure Functions to reload the referenced assemblies? | <p>I've been referencing external assemblies trying to work around the issue noted here: <a href="https://stackoverflow.com/questions/38314334/how-do-i-reference-a-portable-net-assembly-from-an-azure-cloud-function">Azure Function Cannot Load Portable Assembly</a>.

How to enable pointer events | <p>I noticed that in my angular app the property </p>

This probably has something to do with the fact that here the <code>pointerEnabled</code> property is <code>undefined</code>.</p>
<p>My question is, how is this property controlled, how can I enabled it?</p> | 2 |
How do I get two different Django projects to communicate? | <p>Like the title says, I have two Django projects. Unlike other SO questions, these are totally different projects, meaning they do not share database, hosting environment, domain name, etc. This is what I want and need, total decoupling between the projects.</p>
<p>However, they have certain models (let's say UserProfile) from one app which I required in both projects. Also, I would like to have only one of the projects to allow sign-in, log-in, forgot/reset password functionality.</p>
<p>My idea is to have RESTful APIs for both of them, but I still have some questions about how to correctly achieve this:</p>
<ul>
<li>what do I do with the duplicate models to keep them in-sync? Do I create endpoints which can be modified by the other project? </li>
<li>how do I proceed with single-sign-on ? Do I need a specialised server for this? I would also like to take advantage of the tools provided by Django, such as having my current user on my request object.</li>
</ul>
<p>I have yet to find a good tutorial or some detailed explanations as to how to achieve all of these, so if anyone has any resources, please let me know.</p>
<p>If my question is not clear enough, please let me know with a comment.</p>
<p>Thank you.</p> | 2 |

<p>The parameters viz., @NewsTitle, @FromDate and @ToDate can either have values or be NULL. If all 3 parameters or NULL, there should be no record selected but if one of them has non-null value, it should select one or more matching records.</p>
<p>If I pass NULL to all 3 parameters, it works as expected i.e., doesn't select any records but it's not working the other way i.e., if one of them one or two of them have non-null values.</p>

</code></pre>
<p>So, for testing purposes, I am trying to bypass those validations. I found some blogs and posts which all drove me to the code snippet below.</p>
<pre><code>/**
Inner class for set a blind TrustManager
**/
public class BlindTrustManager implements X509TrustManager {
public X509Certificate[] getAcceptedIssuers() {
return new X509Certificate[0];
}
public void checkClientTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
}
}
/*Get the port instance of the web service interface created by JAX-WS*/
SolicitarBaixaPortType port = InvoiceWriteOffWebService.getInstance(serviceName, wsdlLocation);
/*set the socket factory*/
SSLContext ctx = SSLContext.getInstance("TLSv1");
ctx.init(null, new TrustManager[] { new BlindTrustManager() }, null);
SSLSocketFactory sslSocketFactory = ctx.getSocketFactory();
((BindingProvider) port).getRequestContext().put(BindingProviderProperties.SSL_SOCKET_FACTORY, sslSocketFactory);
((BindingProvider) port).getRequestContext().put(com.sun.xml.internal.ws.client.BindingProviderProperties.SSL_SOCKET_FACTORY, sslSocketFactory);
/*message is the Object Jax generated*/
response = port.solicitarBaixaOperation(message);
</code></pre>
<p>Although I had set the <em>SSLSocketFactory</em> the <em>CertificateExpiredException</em> is still be throwing. So it raises the following questions:</p>
<ol>
<li>Am I doing it right?</li>
<li>How can I be sure that the connection sees my <em>BlindTrustManager</em> class? For I can't see any mention of it on the log.</li>
<li>How can I be sure of the right String that I need to pass to my <em>BindingProvider</em> request context for it can find my <em>SSLSocketFactory</em>?</li>
<li>Is there some other configuration that I must do in JBoss?</li>
</ol>
<p>Thanks</p> | 2 |

-------- Recommendations -----------------------------------------------------
General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
MySQL started within last 24 hours - recommendations may be inaccurate
Reduce your overall MySQL memory footprint for system stability
Enable the slow query log to troubleshoot bad queries
When making adjustments, make tmp_table_size/max_heap_table_size equal
Reduce your SELECT DISTINCT queries without LIMIT clauses
Variables to adjust:
*** MySQL's maximum memory usage is dangerously high ***
*** Add RAM before increasing MySQL buffer variables ***
tmp_table_size (> 16M)
max_heap_table_size (> 16M)
