100% height div between header and footer | <p>I am trying to create a webpage layout with a header/footer (100% width, 145px height), a 'main area' between the header/footer (100% width, dynamic height), and a container around the content that is a unique background color (860px width, dynamic height but is always 'flush' against the footer). </p>
<p><strong>(<a href="http://jsfiddle.net/qC8z5/164/">See Example for a visual</a>)</strong> </p>
<p>The problem I am having is I can't seem to have the 'content container' always be flush with the footer when there is minimal content. Using a setup like the <strong>(<a href="http://jsfiddle.net/qC8z5/164/">original example</a>)</strong> results in the footer floating over the content if there is a respectable/'normal' amount of content or if the window is resized.</p>
<p>And the Following CSS results in a gap between the content and the footer.</p>
<pre><code>html,body{
margin:0;
padding:0;
height:100%;
background:yellow;
}
.wrap{
min-height:100%;
position:relative;
}
header{
background:blue;
padding:10px;
}
#content{
height:100%;
width: 400px;
margin:0 auto;
background:orange;
padding:30px;
}
footer{
background:blue;
position:absolute;
bottom:0;
width:100%;
height:60px;
}
</code></pre>
<p>How can I make the content container be the full height of the screen when content is minimal and have the footer 'stick' to the bottom of the page, while also being dynamic to resize appropriately if there is a normal amount of content (footer is always at the bottom of the content)?</p>
<p>Thank you!</p> | 0 |
javax.net.ssl.SSLHandshakeException:No appropriate protocol. How to force Java to use TLSv1.2 for sending mail? | <p>I am trying to use JavaMailSender to send mails in spring boot, but I am getting this error:</p>
<pre><code>javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate). Failed messages: javax.mail.MessagingException: Could not convert socket to TLS;
nested exception is:
javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)
</code></pre>
<p>After doing some reading, I found it is because we are using TLSv1 or TLSv1.1 which is outdated, and we should use v1.2 or higher. I tried to add ssl.protocols property in application.yml with value TLSv1.2, but it does not seem to work. Here is my application.yml:</p>
<pre><code>spring:
mail:
host: smtp.gmail.com
port: 587
username: ******@gmail.com
password: *******
protocol: smtp
tls: true
properties.mail.smtp:
auth: true
ssl.trust: smtp.gmail.com
starttls.required: true
starttls.enabled: true
ssl.protocols: TLSv1.2
</code></pre>
<p>and here is the method that sends the mail:</p>
<pre><code>public void sendEmail(String to, String subject, String body) {
logger.info("Sending mail to : " + to);
SimpleMailMessage mail = new SimpleMailMessage();
mail.setTo(to);
mail.setSubject(subject);
mail.setText(body);
try {
javaMailSender.send(mail);
logger.info("Mail sent to " + to);
} catch (Exception e) {
logger.error("Could not send mail to " + to + ". Exception : " + e.getMessage());
}
}
</code></pre>
<p>I updated JavaMailSender version but it didn't fix the issue. The only thing that worked was removing TLSv1 and TLSv1.1 from jdk.tls.disabledAlgorithms as suggested in <a href="https://stackoverflow.com/a/68238768/8198017">this answer</a>, but it is only a temporary fix. How can make the mail sender use TLSv1.2 or higher? Is there anything wrong in the way I am defining the ssl.protocols property in application.yml?</p>

How to provide a password for PostgreSQL's createdb non-interactively? | <p>I have a task in phing where before tests I drop the database if exists and create it. This is run on Jenkins.
I want to do it with createdb like this:</p>
<pre><code><exec command="createdb my_database" />
</code></pre>
<p>The thing is that the createdb is asking me to authenticate and adding -Umy_user parameter is not a problem - the issue is that I cannot specify a password in the createdb command. And I don't want to create a role for the system user ("jenkins" in this case). Is there a solution for that ? </p> | 0 |
How to run Git server on Windows? | <p>How can I share a Git repo on Windows?

Is there a way to create transparent windows with Tkinter? | <p>I'm trying, ultimately, to create "oddly-shaped windows" with Python using the Tkinter module. But for now I will settle for being able to make the background transparent while keeping child widgets fully-visible.</p>
<p>I'm aware this is done with wxPython and some other modules, but I'm inquiring as to the limits of Tkinter.</p>
<p>Can Tkinter create a clear Canvas or Frame? Can it pack UI elements without a canvas or frame? Can individual UI elements be transparent?</p>
<p>Can it pass mouse-click locations back to the system for processing any windows below it in the Z stack?</p> | 0 |

ExecuteReader returns no results, when inspected query does | <p>Consider the following code:</p>
<pre><code> StringBuilder textResults = new StringBuilder();
using(SqlConnection connection = new SqlConnection(GetEntityConnectionString()))
{
connection.Open();
m.Connection = connection;
SqlDataReader results = m.ExecuteReader();
while (results.Read())
{
textResults.Append(String.Format("{0}", results[0]));
}
}
</code></pre>
<p>I used Activity Monitor within Sql Server Mgmt Studio on the database to inspect the exact query that was being sent. I then copied that query text to a query editor window within SSMS, and the query returned the expected results. However, <code>SqlDataReader results</code> is always empty, indicating "The enumeration returned no results."</p>
<p>My suspicion is that somehow the results are not being returned correctly, which makes me think there's something wrong with the code above, and not the query itself being passed.</p>
<p>Is there anything that would cause this in the code above? Or something I've overlooked?</p>
<p><strong>EDIT:</strong></p>
<p>Here is the query as indicated by the SQLCommand object:</p>
<pre><code>SELECT DISTINCT StandardId,Number
FROM vStandardsAndRequirements
WHERE StandardId IN ('@param1','@param2','@param3')
ORDER BY StandardId
</code></pre>
<p>Here is the query as it appears in Activity Monitor:</p>
<pre><code>SELECT DISTINCT StandardId,Number
FROM vStandardsAndRequirements
WHERE StandardId IN ('ABC-001-0','ABC-001-0.1','ABC-001-0')
ORDER BY StandardId
</code></pre>
<p>The query is working against a single view.</p>
<p>When I ran the second query against the database, it returned 3 rows.</p>
<p>The SqlDataReader indicates 0 rows.</p> | 0 |

pandas drops index index on merge in Python? | <p>I am merging two dataframes using <code>merge(..., how='left')</code> since I want to retain only entries that match up with the "left" dataframe. The problem is that the merge operation seems to drop the index of my leftmost dataframe, shown here:</p>
<pre><code>import pandas
df1 = pandas.DataFrame([{"id": 1,
"name": "bob"},
{"id": 10,
"name": "sally"}])
df1 = df1.set_index("id")
df2 = pandas.DataFrame([{"name": "bob",
"age": 10},
{"name": "sally",
"age": 11}])
print "df1 premerge: "
print df1
df1 = df1.merge(df2, on=["name"],
how="left")
print "merged: "
print df1
# This is not "id"
print df1.index
# And there's no "id" field
assert ("id" in df1.columns) == False
</code></pre>
<p>Before the merge, <code>df1</code> was indexed by <code>id</code>. After the merge operation, there's just the default numeric index for the merged dataframe and the <code>id</code> field was dropped. How can I do this kind of merge operation but retain the index of the leftmost dataframe? </p>
<p>To clarify: I want all the columns of <code>df2</code> to be added to every entry in <code>df1</code> that has the matching <code>id</code> value. If an entry in <code>df2</code> has an <code>id</code> value not in <code>df1</code>, then that shouldn't be merged in (hence the <code>how='left'</code>).</p>
<p><strong>edit</strong>: I could as a hack do: <code>df1.reset_index()</code> but merging and then set the index again, but I prefer not to if possible, it seems like merge shouldn't have to drop the index. thanks.</p> | 0 |

Right way to format date with strings like today, yesterday, tomorrow etc | <p>I have a date textview. And my textview holds a date string like 2011.09.17. Well I still do want to have that but I also want to add some more user friendly info for some specific dates like today or yesterday. For example if today is 2011.09.17 I want my textview to have value of yesterday instead 2011.09.16 and today instead 2011.09.17.</p>
<p>well I already managed to do this :), but in the ugly way :(. I do this with a lot of 'if->than' which is really uglly and what ever I want to add some new rule like if the date is older than one year I want to put string like last year or so.... I really need to add ugly logic.</p>
<p>My question is is there a nicer way to do this ? is there something like design pattern for this ? What is the recommended way to do this ? I am sure that many people have encounter this kind of problems</p>
<p>if there some bather approach than thousand of ifs ? if not thanks any way at least I will stop searching for bather solution</p>
<p>any suggestions , snippet or so will be appreciated</p>

Qt: How to resize a window to its new content | <p>I have a window containing a <code>QScrollArea</code> with a couple widgets in it.</p>
<p>Until now, I was creating the <code>QScrollArea</code> and its child widgets in the constructor of my window, and then I was resizing the window vertically to fit its content using <code>resize(400, sizeHint().height())</code>. So far, so good.</p>
<p>Now, I'm adding or removing widgets in the <code>QScrollArea</code> at runtime. What should I do, after having added or removed widgets, to make the window fits its content vertically? Should I call <code>adjustSize()</code>? <code>resize(sizeHint())</code>? Should there be a call to <code>layout->activate()</code> or maybe <code>updateGeometry()</code> first? Which size policies actually matter in this case? The ones of the window, or of the scroll area, or both? I tried to set them all to <code>Expanding</code>.</p>
<p>I'm using Qt 4.6 on Windows.</p> | 0 |
Setting near plane in OpenGL | <p>i have implemented first person camera in OpenGL, but when i get closer to an object it starts to disappear, so i want to set near plane close to zero so i could get closer to the objects. So if anybody can tell me what is the best way to do that.
Thank you. </p> | 0 |
Connecting to telnet server and send/recieve data | <p>So I am trying to connect to my telnet server, which works. It recives the first lot of data from the server which is us being asked to enter password to connect. But when I type in the password it does nothing and nothing that is recieved is printed to my console.</p>
<p>An example of the output is as follows:</p>

Using std::ostream as argument to a print function | <p>I have always used <code>cout</code> to print the statement but now I want learn printing by <code>passing the stream</code>, something like <code>void print(std::ostream&) const;</code> my current print function looks like</p>

How to read from a text file compressed with 7z? | <p>I would like to read (in Python 2.7), line by line, from a csv (text) file, which is 7z compressed. I don't want to decompress the entire (large) file, but to stream the lines.</p>
<p>I tried <code>pylzma.decompressobj()</code> unsuccessfully. I get a data error. Note that this code doesn't yet read line by line:</p>
<pre><code>input_filename = r"testing.csv.7z"
with open(input_filename, 'rb') as infile:
obj = pylzma.decompressobj()
o = open('decompressed.raw', 'wb')
obj = pylzma.decompressobj()
while True:
tmp = infile.read(1)
if not tmp: break
o.write(obj.decompress(tmp))
o.close()

Codeigniter Pagination From Database limit, offset | <p>I started a web application in CI 3.0, everything working smooth, I got my pagination working, but there is a problem wich I cannot figure out...</p>
<p>For example, I have the following URL: <strong>localhost/statistics/api_based</strong>
When navigate, $query results are displayed, links are generated, OK.
But, when I navigate to <strong>page 2</strong> for example, the URL will become:
<strong>localhost/statistics/dll_based/index/2</strong> and <strong>page 3</strong> will become <strong>localhost/statistics/api_based/index/3</strong> , so therefore I am using segments.
Now the problem is the query that is generated:</p>
<pre><code>SELECT * FROM `shield_api` ORDER BY `id` ASC limit 20 offset 2
</code></pre>
<p><strong>offset 2</strong> - is the page number 2, and it should be 20, if I am correct.
I am displaying 20 results per page, so first page is correctly showing results from 1 - 20, but then page 2 will display results from 2 - 21, so you get my point, it`s not OK...</p>
<p>Here is my controller:</p>
<pre><code>function index($offset = 0) {
// Enable SSL?
maintain_ssl ( $this->config->item ( "ssl_enabled" ) );
// Redirect unauthenticated users to signin page
if (! $this->authentication->is_signed_in ()) {
redirect ( 'account/sign_in/?continue=' . urlencode ( base_url () . 'statistics/api_based' ) );
}
if ($this->authentication->is_signed_in ()) {
$data ['account'] = $this->account_model->get_by_id ( $this->session->userdata ( 'account_id' ) );
}
$per_page = 20;
$qry = "SELECT * FROM `shield_api` ORDER BY `id` ASC";
//$offset = ($this->uri->segment ( 4 ) != '' ? $this->uri->segment ( 4 ) : 0);

Using .tupled method when companion object is in class | <p>I am in the process of migrating from Slick to Slick 2, and in Slick 2 you are meant to use the <code>tupled</code> method when projecting onto a case class (as shown here <a href="http://slick.typesafe.com/doc/2.0.0-RC1/migration.html" rel="nofollow noreferrer">http://slick.typesafe.com/doc/2.0.0-RC1/migration.html</a>)</p>
<p>The problem is when the case class has a companion object, i.e. if you have something like this</p>
<pre><code>case class Person(firstName:String, lastName:String) {
}
</code></pre>
<p>Along with a companion object</p>
<pre><code>object Person {
def something = "rawr"
}
</code></pre>
<p>In the same scope, the <code>tupled</code> method no longer works, because its trying to run <code>tupled</code> on the <code>object</code>, instead of the <code>case class</code>.</p>
<p>Is there a way to retrieve the <code>case class</code> of <code>Person</code> rather than the <code>object</code>, so you can call <code>tupled</code> properly?</p> | 0 |
JQuery DatePicker: How to add a custom class | <p>I need to apply a custom style to my datepicker but can't work out how to add a custom class to the datepicker. I am defining my date picker as follows:</p>

showOn: 'button',
buttonImage: '/Content/images/icon-calendar.gif',
buttonImageOnly: true
}, $.datepicker.regional['en-GB']);
</code></pre>
<p>How do I add a custom class to the datepicker div?</p>
<pre><code><div class="ui-datepicker ui-widget ui-widget-content ui-helper-clearfix ui-corner-all ui-helper-hidden-accessible MY_CLASS_GOES_HERE" id="ui-datepicker-div" style="position: absolute; top: 154px; left: 499px; z-index: 1; display: none;">
</code></pre>
<p>I know I can write:</p>
<p><code>$("#ui-datepicker-div).addClass("MY_CLASS_GOES_HERE")</code> </p>
<p>..but can I rely on the datepicker always having an ID of "ui-datepicker-div"?? Is their a more elegant way of doing this?</p>

Google Chart arrayToDataTable formatted value not working | <p>I am followinf the google Chart documentation for <a href="https://google-developers.appspot.com/chart/interactive/docs/datatables_dataviews?hl=en#arraytodatatable" rel="nofollow">arrayToDataTable</a> and the example states that I can use formatted values, like that:</p>
<pre><code>var data = google.visualization.arrayToDataTable([
['Employee Name', 'Salary'],
['Mike', {v:22500, f:'18,500'}],
...
</code></pre>
<p>where <strong>f:'18,500</strong> is the formatted value to show. My code looks identical:</p>
<pre><code>var data = google.visualization.arrayToDataTable([
['Category', 'Amount'],
['Food', {v:5595.819984, f:'5.595,82'}],
['Home', {v:1890.530002, f:'1.890,53'}],
['Mail', {v:8.380000, f:'8,38'}],
['Train', {v:564.899998, f:'564,90'}],
['Photo', {v:959.119995, f:'959,12'}],
['Lego', {v:428.760004, f:'428,76'}],
...
</code></pre>
<p>but the chart does not even shows, crashing. If I take out the formatted data, it works perfectly.
What I am doing wrong? How can I use a better looking version to show the values on the chart? </p> | 0 |

Using Twitter Bootstrap together with Wordpress | <p>How do I use Wordpress together with Twitter Bootstrap? I know how to set up a Wordpress page and I've already worked with Bootstrap, but now I want to use these two together for the first time.</p>
<p>For my Wordpress projects I normally just installed Wordpress and started from scratch with creating a new theme. For my Bootstrap projects I always used Initializr to build a template.</p>
<p>Now using Google I found various "Bootstrap themes" and plugins , do I need one of those? I want to customize the bootstrap look with my own colors etc. using LESS, that's why I am asking. I am just having trouble to understand how these two will work together and I haven't found any good resource for it.</p> | 0 |
java packages: cannot find symbol | <p>I'm having a strange error. I have 2 classes in the same package but they can't find each other. From what I remember, as long as the classes are in the same package, they should be able to call each other's methods. </p>
<p>My code looks similar to this:</p>
<p>in A.java:</p>
<pre><code>package com.mypackage;
public class A{
public static int read(){
//some code
}
}
</code></pre>
<p>in B.java:</p>
<pre><code>package com.mypackage;
public class B{
public static void main(String args[]){
int x = A.read();
}
}
</code></pre>
<p>and it's giving me a <code>cannot find symbol variable A</code> error.</p>
<p>Both of these classes depend on some <code>.jar</code> files, but I've already included the path of those jars to <code>CLASSPATH</code> and <code>A.java</code> compiled fine, but B can't find A for some reasons...</p>
<p>When I remove the <code>package com.mypackage;</code> in both classes then they compile fine. </p> | 0 |

Flutter - Container width and height fit parent | <p>I have a <code>Card</code> widget which includes <code>Column</code> with several other Widgets. One of them is <code>Container</code>.</p>

Get the number of digits in an int | <p>How do I detect the length of an integer? In case I had le: int test(234567545);</p>
<p>How do I know how long the int is? Like telling me there is 9 numbers inside it??? </p>

<pre><code>char buffer_length[100];
// assign directly to a string.
sprintf(buffer_length, "%d\n", 234567545);
string sf = buffer_length;
cout <<sf.length()-1 << endl;

How to move a marker in Google Maps API | <p>I'm using the Google Maps API V3 and I'm trying to make a marker move across the screen. Here's what I have:</p>
<pre><code><!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#map_canvas { height: 100% }
</style>
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?sensor=false">
</script>
<script type="text/javascript">
function initialize() {
var myLatLng = new google.maps.LatLng(50,50);
var myOptions = {
zoom: 4,
center: myLatLng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
image = 'bus.gif';
marker = new google.maps.Marker({position: myLatLng, map: map, icon: image});
marker.setMap(map);
}
function moveBus()
{
// Move Bus

<body onload="initialize()">

moveBus();
</script>
<div id="map_canvas" style="height: 500px; width: 500px;"></div>
</body>
</html>
</code></pre>
<p>Now what I've tried is replacing // Move Bus with</p>
<pre><code>marker.setPosition(new google.maps.LatLng(0,0));
</code></pre>
<p>But that didn't do anything. That's the command I saw on the API reference. I'm also relatively new to Javascript, so it might be a JS error on my part.</p> | 0 |

Cannot understand numpy argpartition output | <p>I am trying to use arpgpartition from numpy, but it seems there is something going wrong and I cannot seem to figure it out. Here is what's happening:</p>
<p>These are first 5 elements of the sorted array <code>norms</code></p>
<pre><code>np.sort(norms)[:5]
array([ 53.64759445, 54.91434479, 60.11617279, 64.09630585, 64.75318909], dtype=float32)
</code></pre>
<p>But when I use <code>indices_sorted = np.argpartition(norms, 5)[:5]</code></p>
<pre><code>norms[indices_sorted]
array([ 60.11617279, 64.09630585, 53.64759445, 54.91434479, 64.75318909], dtype=float32)
</code></pre>
<p>When I think I should get the same result as the sorted array?</p>
<p>It works just fine when I use 3 as the parameter <code>indices_sorted = np.argpartition(norms, 3)[:3]</code></p>
<pre><code>norms[indices_sorted]
array([ 53.64759445, 54.91434479, 60.11617279], dtype=float32)
</code></pre>
<p>This isn't making much sense to me, hoping someone can offer some insight?</p>
<p>EDIT: Rephrasing this question as whether argpartition preserves order of the k partitioned elements makes more sense.</p> | 0 |

Nginx variable for subdomain? | <p>I need a Guru's advice.</p>
<p>On Nginx's <code>conf</code> file, I would like to get the subdomain as a variable in order to redirect accesses as follow.</p>
<ul>
<li>ACCESS: <code>http://userX.example.com/?hoo=bar</code></li>
<li>REDIRECT: <code>http://example.com/userX/?hoo=bar</code></li>
</ul>
<p>But I get</p>
<ul>
<li>REDIRECT: <code>http://example.com/userX.example.com/?hoo=bar</code></li>
</ul>
<p>My current <code>_http.conf</code> settings are like below. So obviously it works so.</p>
<pre><code>## default HTTP
server {
listen 80;
server_name default_server;
return 301 http://example.com/$host$request_uri;
}
</code></pre>
<p>Are there any vaiables or ways to do like below?</p>
<pre><code>## default HTTP
server {
listen 80;
server_name default_server;
return 301 http://example.com/$subdomain$request_uri;
}
</code></pre>
<p>I know if the subdomain part is limited it can be redirected, but I have to add them each time and I want it to keep as simple as possible.</p>
<p>Is there any simple way to do so?</p>
<p><strong>[ENV]</strong>: CentOS:7.3.1611, nginx: nginx/1.13.3, *.example.com is targetted to the same server in NS settings.</p>
<hr>
<h3>Conclusion (2017/12/13)</h3>
<p>Use a regular expression:</p>
<pre><code>server {
listen 80;
server_name ~^(?<subdomain>.+)\.example\.com$;
return 301 http://example.com/$subdomain$request_uri;
}
</code></pre>

Why is the first item in select menu always empty? | <p>Using CakePHP, I created select-option form element with:</p>
<pre><code>echo $form->select('items', $numeration , array('selected' => 0));
</code></pre>
<p>It creates selection box, but the first option is always empty.</p>
<p>How can I get rid of that empty option? I did not manage to do anything with <code>showEmpty</code> option...</p>
<p>please help....
:-((</p>
<p>UPDATED: </p>
<p>cakephp code </p>
<pre><code>echo $form->select('myOptions', array(1 => 'a', 2 => 'b', 3 => 'c'), array('empty'=>false));

<p>creates next html:</p>
<pre><code><select id="myOptions" name="data[myOptions]">
<option selected="selected" value=""></option>
<option value="1">a</option>
<option value="2">b</option>
<option value="3">c</option>

Dialog Box like JOptionPane in JavaFX | <p>I found this article <a href="http://code.makery.ch/blog/javafx-2-dialogs/" rel="nofollow noreferrer">JavaFX 2 Dialogs</a> and I am using it. But this dialog accepts only Stage Object. Is there any option to display dialog box which will accept AnchorPane as its parent. That Is similar to JoptionPane where we can pass any object which are derived from Component for example JPanel, JTitlePane, etc. And the dialog box I am using it is bieng display on task bar of windows also (passing null as parent). I want show a message like this </p>
<p><img src="https://i.stack.imgur.com/sd1vR.png" alt="enter image description here"></p>

$http request before AngularJS app initialises? | <p>In order to determine if a user's session is authenticated, I need to make a $http request to the server before the first route is loaded. Before each route is loaded, an authentication service checks the status of the user and the access level required by the route, and if the user isn't authenticated for that route, it redirects to a login page. When the app is first loaded however, it has no knowledge of the user, so even if they have an authenticated session it will always redirect to the login page. So to fix this I'm trying to make a request to the server for the users status as a part of the app initialisation. The issue is that obviously $http calls are asynchronous, so how would I stop the app running until the request has finished?</p>

How to handle Visual Studio 2010 Not Responding? | <p>First of all, I am not asking the same question here. ( This may be a duplicate post on Stack Overflow.)

<p>And a lot more...</p>
<p>My <strong>CPU</strong> is 4th Generation Intel Core i7 and <strong>memory</strong> capacity is 8 GB. I think it is more than recommended hardware requirements.</p>
<p><strong>Problem:</strong>
My visual studio hangs on these situations.</p>
<ol>
<li>Opening a solution (Hangs for a minute when I open a file from solution explorer)</li>
<li>Running the debugging (Freezes consistently when I click on debug button) and</li>
<li>Stopping the debugging (Freezes immediately after the UI returns to the Developer layout after debugging)</li>
</ol>
<p><strong>I have tried the following steps</strong>:</p>
<ol>
<li>I ensured that I deleted all the breakpoints in the solution.</li>
<li>I ensured that I am not using any resources from network drive. </li>
<li>I ensured Step over properties is enabled.</li>
<li>I ensured Enable .NET Framework source stepping is NOT enabled.</li>
<li>I start visual studio with <code>SafeMode</code> to suppress extensions</li>
<li>I cleared watch window.</li>
<li>I cleaned and rebuilt the solution.</li>
</ol>
<p>Before I encounter this problem, I installed "Install Web Components" Visual Studio Add-In a few weeks ago. May be because of extensions and add-ins?</p>

Redirect C++ std::clog to syslog on Unix | <p>I work on Unix on a C++ program that send messages to syslog.</p>
<p>The current code uses the <strong>syslog</strong> system call that works like printf.</p>
<p>Now I would prefer to use a stream for that purpose instead, typically the built-in <strong>std::clog</strong>. But clog merely redirect output to stderr, not to syslog and that is useless for me as I also use stderr and stdout for other purposes.</p>
<p>I've seen in <a href="https://stackoverflow.com/questions/665509/redirecting-standard-output-to-syslog">another answer</a> that it's quite easy to redirect it to a file using rdbuf() but I see no way to apply that method to call syslog as openlog does not return a file handler I could use to tie a stream on it.</p>
<p>Is there another method to do that ? (looks pretty basic for unix programming) ? </p>
<p><strong>Edit:</strong> I'm looking for a solution that does not use external library. What @Chris is proposing could be a good start but is still a bit vague to become the accepted answer.</p>
<p><strong>Edit</strong>: using Boost.IOStreams is OK as my project already use Boost anyway.</p>
<p>Linking with external library is possible but is also a concern as it's GPL code. Dependencies are also a burden as they may conflict with other components, not be available on my Linux distribution, introduce third-party bugs, etc. If this is the only solution I may consider completely avoiding streams... (a pity).</p> | 0 |

start/play embedded (iframe) youtube-video on click of an image | <p>I'm trying to start playing an embedded youtube video by clicking an image. The idea is to have an image on top of a video, and when the image is clicked it fades out and starts playing the video.</p>
<p>I'm using jquery to fade the image, and was hoping to find a way to play or click the video using jquery as well. </p>
<p>The fading is working fine, but I can't figure out how to trigger the video to play.
I got it to work on a couple of browsers by setting the video to autoplay and hide it, and then fade in the video when the image was clicked. On most browsers the video would autoplay when faded in, but in chrome it started to autoplay even when it was hidden. It didn't work well in iOS either.</p>
<p>Since I'm pretty new at this, I'm not even sure if I'm writing it 100% correct, but I've tried something like this without success:</p>
<pre><code> $('#IMAGE').click(function() { $('#VIDEO').play(); });
</code></pre>
<p>So, how would I go about to make the video play on an image click?
Is there a way to play the video when the image is clicked, just using jquery?</p>

How does the @property decorator work in Python? | <p>I would like to understand how the built-in function <code>property</code> works. What confuses me is that <code>property</code> can also be used as a decorator, but it only takes arguments when used as a built-in function and not when used as a decorator.</p>
<p>This example is from the <a href="http://docs.python.org/3/library/functions.html#property" rel="noreferrer">documentation</a>:</p>
<pre><code>class C:
def __init__(self):
self._x = None
def getx(self):
return self._x
def setx(self, value):
self._x = value
def delx(self):
del self._x
x = property(getx, setx, delx, "I'm the 'x' property.")
</code></pre>
<p><code>property</code>'s arguments are <code>getx</code>, <code>setx</code>, <code>delx</code> and a doc string.</p>
<p>In the code below <code>property</code> is used as a decorator. The object of it is the <code>x</code> function, but in the code above there is no place for an object function in the arguments.</p>
<pre><code>class C:
def __init__(self):
self._x = None
@property
def x(self):
"""I'm the 'x' property."""
return self._x
@x.setter
def x(self, value):
self._x = value
@x.deleter
def x(self):
del self._x
</code></pre>
<p>How are the <code>x.setter</code> and <code>x.deleter</code> decorators created in this case?</p> | 0 |
How Should VSCode Be Configured To Support A Lerna Monorepo? | <p>I have a <a href="https://github.com/lerna/lerna" rel="noreferrer">lerna</a> monorepo containing lots of packages.</p>
<p>I'm trying to achieve the following:</p>
<ol>
<li>Ensure that VSCode provides the correct import suggestions (based on package names, not on relative paths) from one package to another.</li>
<li>Ensure that I can 'Open Definition' of one of these imports and be taken to the src of that file.</li>
</ol>
<p>For 1. I mean that if I am navigating code within package-a and I start to type a function exported by package-b, I get a suggestion that will trigger the adding of an import: `import { example } from 'package-b'.</p>
<p>For 2. I mean that if I alt/click on the name of a function exported by 'package-b' while navigating the file from a different package that has imported it, I am taken to '/packages/namespace/package/b/src/file-that-contains-function.js',</p>
<p>My (lerna) monorepo is structured as standard, for example here is a 'components' package that is published as <code>@namespace/components</code>.</p>
<pre><code>- packages
- components
- package.json
- node_modules
- src
- index.js
- components
- Button
- index.js
- Button.js
- es
- index.js
- components
- Button
- index.js
- Button.js
</code></pre>
<p>Note that each component is represented by a directory so that it can contain other components if necessary. In this example, <code>packages/components/index</code> exports <code>Button</code> as a named export. Files are transpiled to the package's <code>/es/</code> directory.</p>
<p>By default, VSCode provides autosuggestions for imports, but it is confused by this structure and, for if a different package in the monorepo needs to use <code>Button</code> for example, will autosuggest all of the following import paths:</p>
<ul>
<li><code>packages/components/src/index.js</code></li>
<li><code>packages/components/src/Button/index.js</code></li>
<li><code>packages/components/src/Button/Button.js</code></li>
<li><code>packages/components/es/index.js</code></li>
<li><code>packages/components/es/Button/index.js</code></li>
<li><code>packages/components/es/Button/Button.js</code></li>
</ul>
<p>However none of these are the appropriate, because they will be rendered as relative paths from the importing file to the imported file. In this case, the following import is the correct import:</p>
<pre><code>import { Button } from '@namespace/components'
</code></pre>
<p>Adding excludes to the project's <code>jsconfig.json</code> has no effect on the suggested paths, and doesn't even remove the suggestions at <code>/es/*</code>:</p>
<pre><code>{
"compilerOptions": {
"target": "es6",
},
"exclude": [
"**/dist/*",
"**/coverage/*",
"**/lib/*",
"**/public/*",
"**/es/*"
]
}
</code></pre>
<p>Explicitly adding paths using the "compilerOptions" also fails to set up the correct relationship between the files:</p>
<pre><code>{
"compilerOptions": {
"target": "es6",
"baseUrl": ".",
"paths": {
"@namespace/components/*": [
"./packages/namespace-components/src/*.js"
]
}
},
}
</code></pre>
<p>At present Cmd/Clicking on an import from a different package fails to open anything (no definition is found).</p>
<p><strong>How should I configure VSCode so that:</strong></p>
<ol>
<li><strong>VSCode autosuggests imports from other packages in the monorepo using the namespaced package as the import value.</strong></li>
<li><strong>Using 'Open Definition' takes me to the src of that file.</strong></li>
</ol>

<p>However, when I enter that command, from Windows PowerShell, Git Bash, and the Command Prompt, I just get several variations of "command not found".</p>
<p>In response, I uninstalled <em>gh-pages</em> from dev-dependencies and reinstalled it as a normal dependency. No change. At this point, I've exhausted all solutions I can think of, and Google has only pulled up people who didn't include the <em>deploy</em> command in package.json.</p> | 0 |

Jenkins store workspace outside docker container | <p>So I have a Jenkins Master-Slave setup, where the master spins up a docker container (on the slave VM) and builds the job inside that container then it destroys the container after it's done. This is all done via the Jenkins' Docker <a href="https://wiki.jenkins-ci.org/display/JENKINS/Docker+Plugin" rel="nofollow noreferrer">plugin</a>.</p>
<p>Everything is running smoothly, however the only problem is that, after the job is done (failed job) I cannot view the workspace (because the container is gone). I get the following error:</p>
<p><a href="https://i.stack.imgur.com/zjpv0.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/zjpv0.png" alt="No Workspace Error"></a></p>
<p>I've tried attaching a "volume" from the host (slave VM) to the container to store the files outside also (which works because, as shown below, I can see files on the host) and then tried mapping it to the master VM:</p>
<p><a href="https://i.stack.imgur.com/QLuFz.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QLuFz.png" alt="Host files"></a></p>
<p>Here's my settings for that particular docker image template:</p>
<p><a href="https://i.stack.imgur.com/S9gXZ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/S9gXZ.png" alt="Docker template"></a></p>
<p>Any help is greatly appreciated!</p>
<p>EDIT: I've managed to successfully get the workspace to store on the host.. However, when the build is done I still get the same error (Error: no workspace). I have no idea how to make Jenkins look for the files that are on the host rather than the container.</p> | 0 |
How do you read from a memory buffer c++ | <p>I am fairly new at C++ and am trying to understand how memory manipulation works. I am used to Java and Python and haven't really been exposed to this. </p>
<p>I am working on a project that has the following structure that doesn't quite make sense to me. </p>
<pre><code>typedef struct
{
size_t size;
char *data;
} data_buffer;
</code></pre>
<p>This structure basically acts as a buffer, with a pointer to the data stored within the buffer and the size of the buffer to allow the program to know how large the buffer is when reading from it.</p>
<p>An example of how the program uses the buffer:</p>
<pre><code>data_buffer buffer = {0};
//Manipulate data here so it contains pertinent information
CFile oFile;
oFile.Write(buffer.data, buffer.size);
</code></pre>
<p>The program mostly uses 3rd party code to read the data found within the buffer, so I am having trouble finding an example of how this is done. My main question is <strong>how do I read the contents of the buffer, given only a pointer to a character and a size?</strong> However, I would also like to understand how this actually works. From what I understand, memory is written to, with a pointer to where it starts and the size of the memory, so I should be able to just iterate through the memory locations, grabbing each character from memory and tagging it onto whatever structure I choose to use, like a CString or a string. Yet, I don't understand how to iterate through memory. Can someone help me understand this better? Thanks.</p> | 0 |
Calling a function within PowerShell ISE | <p>Could someone tell me why I can not call a function within a PowerShell script? See below my code:</p>
<pre><code>Write-Host "Before calling Function."
testFunction
function testFunction()
{
Write-Host "Function has been called"
}
</code></pre>
<p>When I run the above code I get the following error message:</p>
<pre>testFunction : The term 'testFunction' is not recognized as the name of a cmdlet,
function, script file, or operable program. Check the spelling of the name, or if
a path was included, verify that the path is correct and try again.

+ testFunction
+ ~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (testFunction:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException</pre>
<p>I'm sure that it must be possible to call functions within the same PowerShell script. Can somebody please help?</p> | 0 |
Core Data VS Sqlite or FMDB....? | <p>Now this might look like a duplicate thread, but my question is that I have read a lot of questions like.. <a href="https://stackoverflow.com/questions/523482/core-data-vs-sqlite-3">Core Data vs SQLite 3</a> and others but these are 2-3 years old. I have also read that FMDB was developed as core data was not supported on iOS, So it should not be used any more. And on the other hand I have read that one should not use core data as a database. </p>
<p><strong>So I am seriously confused,whether I should use core data for object storage or not</strong>. I mean on what basis I should decide which to use? Are there any guidelines provided by apple or someone else.. or is it something that will come to me with time.?</p> | 0 |
What is the most pythonic way to check if multiple variables are not None? | <p>If I have a construct like this:</p>
<pre><code>def foo():
a=None
b=None
c=None
#...loop over a config file or command line options...
if a is not None and b is not None and c is not None:
doSomething(a,b,c)
else:
print "A config parameter is missing..."
</code></pre>
<p>What is the preferred syntax in python to check if all variables are set to useful values? Is it as I have written, or another better way?</p>
<p>This is different from this question:
<a href="https://stackoverflow.com/questions/3965104/not-none-test-in-python">not None test in Python</a> ... I am looking for the preferred method for checking if many conditions are not None. The option I have typed seems very long and non-pythonic.</p> | 0 |
Styling of Select2 dropdown select boxes | <p>I'm using Select2 in a project to style some select boxes in a search form. I managed to change the gradient background of the arrow container to a black gradient:</p>
<pre class="lang-css prettyprint-override"><code>.select2-container .select2-choice .select2-arrow {
background-image: -khtml-gradient(linear, left top, left bottom, from(#424242), to(#030303));
background-image: -moz-linear-gradient(top, #424242, #030303);
background-image: -ms-linear-gradient(top, #424242, #030303);
background-image: -webkit-gradient(linear, left top, left bottom, color-stop(0%, #424242), color-stop(100%, #030303));
background-image: -webkit-linear-gradient(top, #424242, #030303);
background-image: -o-linear-gradient(top, #424242, #030303);
background-image: linear-gradient(#424242, #030303);
}
</code></pre>
<p>I would like the arrow to be white, but unfortunately Select2 is using a background image for the different icons instead of font-awesome or something similar, so there's no way to just change the color with CSS.</p>
<p>What would be the easiest way to make the arrow white instead of the default grey? Do I really have to replace the background png (select2.png and select2x2.png) with my own? Or is there an easier method?</p>
<p>Another question I have is how to change the height of the select boxes. I know how to change the height of the dropdown box in opened state, but I want to change the height of the selectbox in closed state. Any ideas?</p> | 0 |

Using the AND and NOT Operator in Python | <p>Here is my custom class that I have that represents a triangle. I'm trying to write code that checks to see if <code>self.a</code>, <code>self.b</code>, and <code>self.c</code> are greater than 0, which would mean that I have Angle, Angle, Angle. </p>
<p>Below you will see the code that checks for A and B, however when I use just <code>self.a != 0</code> then it works fine. I believe I'm not using <code>&</code> correctly. Any ideas? Here is how I am calling it: <code>print myTri.detType()</code></p>
<pre><code>class Triangle:
# Angle A To Angle C Connects Side F
# Angle C to Angle B Connects Side D
# Angle B to Angle A Connects Side E
def __init__(self, a, b, c, d, e, f):
self.a = a
self.b = b
self.c = c
self.d = d
self.e = e
self.f = f
def detType(self):
#Triangle Type AAA
if self.a != 0 & self.b != 0:
return self.a
#If self.a > 10:
#return AAA
#Triangle Type AAS
#elif self.a = 0:
#return AAS
#Triangle Type ASA
#Triangle Type SAS
#Triangle Type SSS
#else:
#return unknown

Regex to match values not surrounded by another char? | <p>This is one of the toughest things I have ever tried to do. Over the years I have searched but I just can’t find a way to do this — match a string not surrounded by a given char, like quotes or greater/less than symbols.</p>
<p>A regex like this could match URLs not in HTML links, SQL table.column values not in quotes, and lots of other things.</p>
<pre><code>Example with quotes:
Match [THIS] and "something with [NOT THIS] followed by" or even [THIS].
Example with <,>, & "
Match [URL] and <a href="[NOT URL]">or [NOT URL]</a>
Example with single quotes:
WHERE [THIS] LIKE '%[NOT THIS]'
</code></pre>
<p>Basically, how do you match a string (THIS) when it is not surrounded by a given char?</p>
<pre><code>\b(?:[^"'])([^"']+)(?:[^"'])\b
</code></pre>
<p>Here is a test pattern: a regex like what I am thinking of would match only the first "quote".</p>
<blockquote>
<p>To quote, "quote me not lest I quote you!"</p>

jQuery load Wordpress pages via ajax | <p>I'm trying to setup a Wordpress theme which loads pages (not posts) with AJAX. I was following <a href="http://www.emanueleferonato.com/2010/04/01/loading-wordpress-posts-with-ajax-and-jquery/" rel="noreferrer">this guide</a> but haven't been able to get the correct pages to load.</p>
<p>The links to the posts are being generated with the post slug</p>
<pre><code>http://local.example.com/slug/
</code></pre>
<p>So I adjusted </p>
<pre><code> jQuery(document).ready(function($){
$.ajaxSetup({cache:false});
$("a.bar").click(function(e){
$('page-loader').show();
var that = $(this).parent();
$('.column').not($(this).parent()).animate({width: 'toggle',opacity:'0.75'}, 700, function() {
});
var post_id = $(this).attr("href");
$("#page-container").load("http://<?php echo $_SERVER[HTTP_HOST]; ?>" + post_id,{id:post_id});
return false;
});
});
</code></pre>
<p>The URL is correct but it doesn't load anything..</p>
<hr>
<pre><code><?php
/*
Template Name: Triqui Ajax Post

?>
<?php
$post = get_post($_POST['id']);

<?php if ($post) : ?>
<?php setup_postdata($post); ?>
