Tablayout+view pager is not displaying the fragment in position 0 | <p>My application has 2 tabs with two different layouts. when i run the application, the fragment which is supposed to be shown in tab1(position 0) displays in tab2, and the fragment which is supposed to be in tab2(position 1) is not displaying. Also when i swipe the screen the tab focus is not changing in the tablayout</p>

How to show buy/sell signals of Amibroker on my webpage? | <p>I want to show the buy/sell signals that Amibroker generates on my website. I tried lot of things but I couldn't find a solution. </p>
<p>It would be even better if I can stream the charts to the website.</p>
<p>The problem is, I don't know how to access the API of Amibroker.(Do they even have it? It is mentioned in their features page, but have not seen any documentation regarding it).</p>
<p>Then, I am not sure how would I connect that to my web server.</p> | 2 |
PHP Soap Server without Soap Client | <p>There are several weeks that I'm trying to create a soap server in php that at first serves a wsdl with authentication header on it and at second it accepts only authenticated users in every request. But I' ve only made it fully working only without authentication. Every search I 've made and every solution I 've found contains a SoapClient,Zend_Soap_Client,nu_soap_client (you name it) and either some kind of wrapper class around my class or only addition of username & password on the client.
But at my solution only the server is in php and client are various programs written in java etc, <strong>not</strong> in php. Here is my code for (I use <a href="https://github.com/zendframework/zend-soap" rel="nofollow">zend</a> here but the idea is the same on plain php) the wsdl generation and the server part:</p>
<pre><code>use Zend\Soap\AutoDiscover as Zend_Soap_AutoDiscover;
use Zend\Soap\Server as Zend_Soap_Server;
if (isset($_GET['wsdl'])) {
$autodiscover = new Zend\Soap\AutoDiscover();
$autodiscover->setClass('MyClass');
$autodiscover->setUri('http://Myclass/path/');
$autodiscover->handle();
exit;
}
$server = new Zend_Soap_Server(null, array(
'uri' => 'http://Myclass/path/',
));
$server->setClass('Myclass');
$server->handle();
</code></pre>
<p>I also used <a href="https://github.com/piotrooo/wsdl-creator" rel="nofollow">piotrooo</a>'s wsdl generator and plain php soap library like this:</p>
<pre><code>use WSDL\WSDLCreator;
// use WSDL\XML\Styles\DocumentLiteralWrapped;
if (isset($_GET['wsdl'])) {
$wsdl = new WSDL\WSDLCreator('Myclass', 'http://Myclass/path/');
$wsdl->setNamespace("http://Myclass/path/");
$wsdl->renderWSDL();
exit;
}
$server = new SoapServer(null, array(
'uri' => 'http://Myclass/path/',
// 'style' => SOAP_DOCUMENT,
// 'use' => SOAP_LITERAL,
));
$server->setClass('Myclass');
$server->handle();
</code></pre>
<p>And my class:</p>
<pre><code>class Myclass
{
public function __construct()
{
/*some db stuff with doctrine*/
}
/**
* @param string $id
* @return object
*/
public function Id($id)
{
/*I'm using doctrine to fetch data from db and then return an object/or array*/
}
}
</code></pre>
<p>At last this is the auto generated wsdl:</p>
<pre><code><definitions name="Myclass" targetNamespace="http://Myclass/path/"><types><xsd:schema targetNamespace="http://Myclass/path/"/></types><portType name="MyclassPort"><operation name="Id"><documentation>Id</documentation><input message="tns:IdIn"/><output message="tns:IdOut"/></operation></portType><binding name="MyclassBinding" type="tns:MyclassPort"><soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/><operation name="Id"><soap:operation soapAction="http://Myclass/path/#Id"/><input><soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://Myclass/path/"/></input><output><soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://Myclass/path/"/></output></operation></binding><service name="MyclassService"><port name="MyclassPort" binding="tns:MyclassBinding"><soap:address location="http://Myclass/path/"/></port></service><message name="IdIn"><part name="id" type="xsd:string"/></message><message name="IdOut"><part name="return" type="xsd:struct"/></message></definitions>
</code></pre>
<p>Annotations vary on each generator.
I also tried nusoap but I was disappointed because of it's pure class method discovery. I must add that I'm testing usage of service with soapui (that's why I don't want php's SoapClient or equivalent examples).
Last I also must say that I tried solutions of adding authentication method inside my class and this worked <strong><em>BUT</em></strong> this didn't prevent unauthenticated user from accessing ws.</p>
<p>A little extra information. As of my research every answer I was found was about SOAPClient for example the $client->__addheader() function etc. Please tell me if I' m wrong or if this can't be done with PHP because I ll have to find someone else to do this for me with another programming language like Java etc.</p>
<p>Thanks in advance</p>

How to can I use custom headers from CloudFront in Apache virtualhost | <p>I have been given a task that I am not really sure how to handle. What I am requested to do is add a custom header to CloudFront and make Apache use this custom header to serve the site. I also need a fallback to normal use when the header is not set. </p>
<p>I have my main website: <strong>www.domain.com</strong> that is setup on CloudFront with the origin set to <strong>prod.domain.com</strong>. The site is setup on the server as <strong>www.domain.com</strong> (this cannot be changed)</p>
<p>What I want to do is set a custom header in CloudFront that will define the site name and use this header in my virtualhost to load the correct site.</p>
<p>For sake of example, I have added the header: <strong>company-host-name</strong> and set the value to <strong>www.domain.com</strong>. CloudFront origin is <strong>prod.domain.com</strong> and have updated the DNS to point to the server IP for this new domain. So far so good but this is now trying to load the <strong>prod.domain.com</strong> from the server. </p>
<p>What I want to do is use the custom header to load the site instead of the default way Apache handles this. Although I still need the fallback if no header is set. I think simply setting this header to the HOST header should suffice.</p>
<p>My Server Specs:</p>
<pre><code># cat /etc/centos-release
CentOS release 6.8 (Final)
# httpd -v
Server version: Apache/2.2.15 (Unix)
Server built: May 11 2016 19:28:33
</code></pre>
<p>I will need to know how to do this in Apache 2.4 also but for now 2.2 is essential.</p>
<p>I have tried playing with the headers and added this to my <code>http.conf</code></p>
<pre><code><IfModule mod_headers.c>
<IfDefine company_host_name>
Header set Host "%{company_host_name}e"
</IfDefine>
</ifModule>
</code></pre>
<p>I was hoping to override the Host header with the custom header value. I think this should suffice but I cannot seem to get this to work.</p>
<p>Perhaps I am over-complicating it and need to take a step back. So I am here asking for help on something I didn't think would be too difficult.</p>
<p>Thanks for any help you can provide.</p>

Adjusting PKG_CONFIG_PATH does not work | <p>I am having problems with installing a package that depends on another package - <code>poppler-glib</code>. I have <code>poppler-glib</code> (newest version) installed with the prefix <code>/home/user/local/poppler-glib</code> with <code>*.pc</code> files present in <code>/home/user/local/poppler-glib/lib/pkgconfig</code>. I have added that path to the <code>PKG_CONFIG_PATH</code> variable (I am on <code>tcsh</code>):</p>
<pre><code>setenv PKG_CONFIG_PATH /home/user/local/poppler-glib/lib/pkgconfig
</code></pre>
<p>Nevertheless, when I try to run the <code>./configure</code> script of the other package, I am getting the following error:</p>
<pre><code>configure: error: Package requirements (poppler-glib >= 0.5.4) were not met:
No package 'poppler-glib' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables POPPLERGLIB_CFLAGS
and POPPLERGLIB_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
</code></pre>
<p>Therefore, question: how can I adjust the <code>PKG_CONFIG_PATH</code> variable to make it visible?</p> | 2 |
Storing large amount of data into Core Data | <p>I'm loading a large amount of data in JSON format (more than 2000 entities) into Core Data whenever user refreshes the page.

Can I resume a Maven lifecycle from an arbritrary phase? | <p>I would like to convince Maven to "continue where it left off". I first do a <code>mvn package</code> to build the package. At a later time I may want to continue the lifecycle to do the integration test etc. by doing a <code>mvn install</code>. In this case I would prefer Maven not to start the lifecycle all over again from the start, but to actually resume at the first phase after <code>package</code> (i.e. <code>pre-integration-test</code>). Is it possible to start the lifecycle at a phase other than the first one?</p> | 2 |

How to cast float to string with no decimal places | <p>I'm using <code>openpyxl</code> to read values from a spreadsheet. These values are being read as floats, I am not entirely sure why.</p>
<pre><code>import openpyxl as opx
wb = opx.load_workbook(SKU_WORKBOOK_PATH, use_iterators=True, data_only=True)
ws = wb.worksheets[0]
for row in ws.iter_rows():
foo = str(int(row[1].internal_value))
</code></pre>
<p>This is throwing the error:</p>
<pre><code>ValueError: invalid literal for int() with base 10: '6978279.0'
</code></pre>
<p>Normally, openpyxl reads in integer values as <code>int</code>, but this time it has read it in a float cast as a string. In the spreadsheet, the value of this cell is <code>6978279</code>.</p>
<p>I am converting this to the string I want with <code>foo = str(int(float(foo)))</code> which results in <code>'6978279'</code> as intended. I could also do <code>foo = foo[:-2]</code>, but this worries me that another cell, which may be read as an <code>int</code> or with more decimal places, would screw things up.</p>
<p>This feels like a terrible, messy way of mashing what I have into what I want. Is there a more pythonic way to do this? Am I reading the <code>xlsx</code> in a way that forces floats? How can I do this without triple casting?</p> | 2 |

How to dynamic deploy for standalone Spring batch using Spring Cloud Task | <p>We are planning to retire the existing legacy java batch applications and recreate it with the latest available batch framework.
Given that we have a large number of batch jobs to be modernised, we are looking for a framework or architecture that would allow us to </p>
<ol>
<li>Develop a batch solution that would allow us to dynamically deploy a new batch as and when they are created, without disturbing the existing deployed applications. - Does Spring cloud Task provide any of this feature. Note: We are looking only to deploy the apps to our local server, and has nothing to do with cloud.</li>
<li>If Spring Batch/Boot can provide us the feature we typically expect from a batch application, what is the special value add to go for Spring Cloud Task? - I wasn't able to completely understand this from the Spring documentation available online.</li>
<li>From the documentation of the Spring Cloud Task, I was able to understand that it allows an application to have many tasks within it. What should I do if each of the tasks have their own library dependencies, which might contradict with the dependencies of other Tasks? So in that case, should each of these tasks moved to a new application or this there a work around for that?</li>

Using collapse/accordion to make a switchable div | <p>In Bootstrap (v3) is it possible to have two divs which are simply switchable, so one div is shown by default, and a button toggles between the two, so one div is always shown?</p>
<p>It feels like "Collapse" and/or "Accordion" should be able to do this but...</p>
<p>"Collapse" doesn't allow for parent elements, to switch between the two and...</p>
<p>"Accordion" allows all of the panels to be hidden.</p>
<p>The same thing can be accomplished with a bit of JQuery but I'm wondering if some use of the data-* attributes may allow me to avoid any JS. Also, I want to use standard Bootstrap classes as much as possible.</p> | 2 |

How to call SuperClass delegate method from SubClass delegate method | <p>I have a <code>SuperClass</code> that implements <code><UIWebViewDelegate></code>, in this class I implemented the method <code>webView:shouldStartLoadWithRequest:navigationType:</code></p>
<pre><code>@interface SuperClass
...
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request1 navigationType:(UIWebViewNavigationType)navigationType {
// SuperClass treatment
}
...
@end
</code></pre>
<p>Then I have a <code>SubClass</code> that extend this <code>SuperClass</code>. the <code>SubClass</code> implements <code><UIWebViewDelegate></code> too, and the method <code>webView:shouldStartLoadWithRequest:navigationType:</code> as well :</p>
<pre><code>@interface SubClass: SuperClass
...
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request1 navigationType:(UIWebViewNavigationType)navigationType {
// SubClass treatment
}
...
@end
</code></pre>
<p>The code works for me, because I need to do a specific treatment for the <code>SubClass</code>.
But in a specific case, I need to call the <code>SuperClass</code> <code>webView:shouldStartLoadWithRequest:navigationType:</code> method. </p>
<p><strong>I need the delegate to execute the <code>SuperClass</code> <code>UIWebViewDelegate</code> methods.</strong></p>
<p>I tried to use <code>super</code> to call the <code>SuperClass</code> method, but with no use!</p>

10 | Jack | 2016-06-17 12:00:08
</code></pre>
<p>and so on. I just want to get a list of all people whose registration date is in the last 7 days. 'registration' column is of DATETIME type </p>
<p>Here's my code in CI model using Query Builder. Already autoload database library</p>
<pre><code> function get_user()
{
$query = $this->db->select('name')
->where('registration','BETWEEN DATE_SUB(NOW(), INTERVAL 7 DAY) AND NOW()')
->get('users');
return $query->result();
}
</code></pre>
<p>It's return empty result without error. Next I try to put query directly like this</p>
<pre><code> function get_user()
{
$query = $this->db>query('SELECT name FROM users WHERE registration BETWEEN DATE_SUB(NOW(), INTERVAL 7 DAY) AND NOW()');
return $query->result();
}
</code></pre>
<p>Also return empty result without error. So out of curiosity I tried to run the same query using native PHP outside Codeigniter. Here's the code :</p>
<pre><code> <?php
$link = mysqli_connect("localhost", "myusername", "mypassword", "mydatabase");
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query = "SELECT name FROM users WHERE registration BETWEEN DATE_SUB(NOW(), INTERVAL 7 DAY) AND NOW()";
$result = mysqli_query($link, $query);
while($row = mysqli_fetch_array($result, MYSQLI_ASSOC)){
echo $row["name"];
echo "<br>";
}
mysqli_free_result($result);
mysqli_close($link);
?>
</code></pre>
<p>And voila...it works and return result as expected. So any idea what's the problem with Codeigniter in this case? Any input will be appreciated. Thanks all</p> | 2 |

Getting the device ID/Handle of a mouse with Raw Input | <p>I'm working on using the raw input api to listen for key presses and mouse clicks. So far I have the keyboard presses working, I'm able to get events to fire for such and read which key was pressed. However, I'm having trouble getting the mouse events to work the same way. </p>
<p>When the message comes in via
<code>WndProc(ref Message)</code>, there's a device handle that doesn't ever match anything from the list of device IDs (keyboards, mice, and HIDs). Moreover, the raw input buffer is empty with all fields being zero.</p>
<p>Does anyone have suggestions on how/why this would happen?</p>
<p>Note, I've been trying to use:
<code>private static extern uint GetRawInputDeviceInfo(IntPtr hDevice, uint command, ref DeviceInfo data, ref uint dataSize);</code> to get any data about the click event's source device, but again the data is also empty/zero.</p>
<p>Thanks</p>
<p>Edit:</p>
<p>On startup I get a list of all devices seen by raw input:</p>
<pre><code>var pRawInputDeviceList = Marshal.AllocHGlobal((int)(dwSize * deviceCount));
GetRawInputDeviceList(pRawInputDeviceList, ref deviceCount, (uint)dwSize);
</code></pre>
<p>Once I have this list of devices I iterate through them and add them to a separate <code>dictionary<deviceID, eventType></code>.</p>
<p>Later, once I receive a message through <code>WndProc(ref Message)</code>, I grab the identifier under <code>message.LParam</code>, but this doesn't match any device ID in my original list.</p> | 2 |
Kubelet fails to update node status | <p>On latest RHEL Atomic Host (Kubernetes 1.2) we are regularly seeing the following entries in the kubelet logs:</p>
<p>kubelet.go:2761] Error updating node status, will retry: nodes "x.y.z" cannot be updated: the object has been modified; please apply your changes to the latest version and try again</p>
<p>This causes the node to temporary go to NotReady. During these NotReady periods, the PODs on the node show Ready, but it looks like Kubernetes stops routing traffic to them, causing us a problem.</p>
<p>In the Go sources I can see that during the heartbeat of a Kubelet it does a GET to fetch the latest status, overwrites it with its own status, and sends the PUT back to the apiserver.</p>

How to optimize performance when repeatedly looping over a big list of objects | <p>I have a simple file that contains two integer values per line (a source integer and a target integer). Each line represents a relation between two values. The file is not sorted and the actual file contains about 4 million lines. After sorting it may look like this:</p>
<pre><code>sourceId;targetId
1;5
2;3
4;7
7;4
8;7
9;5
</code></pre>
<p>My goal is to create a new object that will represent all unique related integers in a list with a unique identifier. The expected output of this example should be the following three objects:</p>
<pre><code>0, [1, 5, 9]
1, [2, 3]
2, [4, 7, 8]
</code></pre>
<p>So groupId 0 contains a group of relations (1, 5 and 9).</p>
<p>Below is my current way to create a list of these objects. The list of Relation objects contains all the lines in memory. And the list of GroupedRelation should be the end result.</p>
<pre><code>public class GroupedRelationBuilder {
private List<Relation> relations;
private List<GroupedRelation> groupedRelations;
private List<String> ids;
private int frameId;

relations.add(new Relation(4, 7));
relations.add(new Relation(8, 7));
relations.add(new Relation(7, 4));
relations.add(new Relation(9, 5));
relations.add(new Relation(2, 3));
// sort
relations.sort(Comparator.comparing(Relation::getSource).thenComparing(Relation::getTarget));
// build the groupedRelations
groupId = 0;
groupedRelations = new ArrayList<>();
for (int i = 0; relations.size() > 0;) {

<p>When I run this small example program, it takes 15 seconds to create 1000 GroupedRelation objects. To create 1 million GroupedRelation it would take 250 minutes.. </p>
<p>I am looking for help in optimizing my code that does get the result I want but simply takes to long.</p>
<p><strong>Is it possible to optimize the iteration in such a way that the expected result is the same but the time it takes to get the expected result is reduced significantly? If this is possible, how would you go about it?</strong></p> | 2 |

* abort - Causes the operation to fail; you will need to downgrade, reinstall, reconfigure this package, or otherwise manually intervene to continue using it. This will usually also impact your ability to install other packages until the installation failure is resolved. * retry - Prompts once more with all the configuration questions (including ones you may have missed due to the debconf priority setting) and makes another attempt at performing the operation. * retry (skip questions) - Immediately attempts the operation again, skipping all questions. This is normally useful only if you have solved the underlying problem since the time the error occurred. * ignore - Continues the operation ignoring dbconfig-common errors.

"""Wordcount exercise
Google's Python class
The main() below is already defined and complete. It calls print_words()
and print_top() functions which you write.
1. For the --count flag, implement a print_words(filename) function that counts
how often each word appears in the text and prints:
word1 count1
word2 count2
...
Print the above list in order sorted by word (python will sort punctuation to
come before letters -- that's fine). Store all the words as lowercase,
so 'The' and 'the' count as the same word.
2. For the --topcount flag, implement a print_top(filename) which is similar
to print_words() but which prints just the top 20 most common words sorted
so the most common word is first, then the next most common, and so on.
Use str.split() (no arguments) to split on all whitespace.
Workflow: don't build the whole program at once. Get it to an intermediate
milestone and print your data structure and sys.exit(0).
When that's working, try for the next milestone.
Optional: define a helper function to avoid code duplication inside
print_words() and print_top().

<p>Here are my questions that course is not answering:</p>
<ol>
<li><p>Where is says the following, I am unsure of what the <code>1</code> and <code>+1</code> mean. Does that mean <code>if the word is not in the list, add it to the list? (word_count[word]=1)</code>? And, I don't understand what each part of this means, where it says <code>word_count[word]=word_count[word] + 1</code>.</p>
<pre><code> if not word in word_count:
word_count[word]=1
else:
word_count[word]=word_count[word] + 1
</code></pre></li>
<li><p>When it says <code>word_count.keys()</code>, I am not sure what that does other than it calls to the key in the dictionary we defined and loaded keys and values into. I just want to understand why the <code>word_count.keys()</code> is there. </p>
<pre><code> words=sorted(word_count.keys())
</code></pre></li>
<li><p><code>word_count</code> is redefined in a couple of locations, and I would like to know why instead of creating a new variable name such as <code>word_count1</code>. </p>
<pre><code> word_count={}
word_count=word_count_dict(filename)
...and also in places outlined in my 1st question.
</code></pre></li>
<li><p>Does <code>if len(sys.argv) != 3:</code> mean that if my arguments are not 3, or my characters not 3 (e.g. <code>sys.argv[1]</code>, <code>sys.argv[2]</code>, <code>sys.argv[3]</code>?</p></li>

Get index of hash with hash key | <p>I have this hash with wins, and I'm sorting it based on how many wins a player has ( making a highscore list). Now I'm getting each value out based on a players id. How do I get the index of the value I got. ( So I can get the highscore placement).</p>
<pre><code>#Highscore list.
highscore = Hash.new
@users.each_with_index do |player, index|
playerTotalGames = @finishedgames.where(log_id: player.id)
playerTotalWins = playerTotalGames.where(winner: true)
highscore[player.id] = playerTotalWins.length.to_i
end
@highscore = highscore.sort_by{ |k, v| v }.reverse.to_h # Sort highscore list

YALMIP outputs "Infeasible" for an easy, feasible SDP | <p>I want to determine whether a given 3x3 matrix is positive-semidefinite or not. To do so, I write the following SDP in YALMIP</p>
<pre><code>v=0.2;
a=sdpvar(1);
b=sdpvar(1);
M=[1 a -v/4 ; b 1 0 ; -v/4 0 0.25];
x=sdpvar(1);
optimize([M+x*eye(3)>=0],x,sdpsettings('solver','sedumi'))
</code></pre>
<p>This program gives me the error "Dual infeasible, primal improving direction found". This happens for any value of v in the interval (0,1].</p>
<p>Given that this problem is tractable, I diagonalized the matrix directly obtaining that the three eigenvalues are the three roots of the following polynomial</p>
<pre><code>16*t^3 - 36*t^2 + (24 - 16*a*b - v^2)*t + (-4 + 4*a*b + v^2)
</code></pre>
<p>Computing the values of the three roots numerically I see that the three of them are positive for sign(a)=sign(b) (except for a small region in the neighborhood of a,b=+-1), for any value of v. Therefore, the SDP should run without problems and output a negative value of x without further complications.</p>
<p>To make things more interesting, I ran the same code with the following matrix</p>
<pre><code>M=[1 a v/4 ; b 1 0 ; v/4 0 0.25];
</code></pre>
<p>This matrix has the same eigenvalues as the previous one, and in this case the program runs without any issues, confirming that the matrix is indeed positive-semidefinite.</p>
<p>I am really curious about the nature of this issue, any help would be really appreciated.</p>
<p>EDIT: I also tried the SDPT3 solver, and results are very similar. In fact, the program runs smoothly for the case of +v, but when i put a minus sign I get the following error</p>
<pre><code>'Unknown problem in solver (Turn on 'debug' in sdpsettings) (Error using & …'
</code></pre>
<p>Furthermore, when I add some restrictions to the variables, i.e., I run the following command</p>
<pre><code>optimize([total+w*eye(3)>=0,-1<=a<=1,-1<=b<=1],w,sdpsettings('solver','sdpt3'))
</code></pre>
<p>Then the error turns to an 'Infeasible problem' error.</p> | 2 |

Allow User to edit button text on long click in Android | <p>I want to allow the App users to change the Button text in Android.

etLabel = (EditText) findViewById(R.id.etName);
btn1.setOnLongClickListener(new View.OnLongClickListener() {

How to convert a column of timestamps HH:MM:SS.xxxxxxx to milliseconds? | <p>I have been trying to figure out how to do this in Python for the better part of a week, but not been able to find anyone to specifically answer this question. I have a log file, where every line is a timestamp with an event, as such:</p>
<pre><code>HH:MM:SS.xxxxxxx \t Event
HH:MM:SS.xxxxxxx \t Event
HH:MM:SS.xxxxxxx \t Event
...
</code></pre>
<p>I have managed to put all this into a list, and figured out how to manipulate that list. What I haven't been able to figure out is how to convert the timestamp (which starts at 0 (well, at one second, really, but roughly 0)) into milliseconds (something I can do in Excel). So every timestamp just represents elapsed time, not an actual o'clock. The seven x's at the end make no sense to me at all, so not sure what they are.</p>
<p>Does anyone have a code snippet that I can use to convert this timestamp into milliseconds?</p> | 2 |

Lock Auth0 for android not returning UserProfile on authentication | <p>I'm using Lock for providing Login functionality in my android App to users. </p>
<p>Here is my code:
private Lock lock;</p>
<pre><code>private LocalBroadcastManager broadcastManager;
private BroadcastReceiver authenticationReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String idToken = intent.getStringExtra("com.auth0.android.lock.extra.IdToken");
String tokenType = intent.getStringExtra("com.auth0.android.lock.extra.TokenType");
Log.i(TAG, "User logged in with " + idToken + " "+ tokenType);
}
};
//Not sure use of this callback though its not being called anytime.
private LockCallback callback = new AuthenticationCallback() {
@Override
public void onAuthentication(Credentials credentials) {
Log.d(TAG, "Authenticated");
}
@Override
public void onCanceled() {
Log.d(TAG, "Authentication cancelled");
}
@Override
public void onError(LockException error) {
Log.d(TAG, "Authentication Error");
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Auth0 auth0 = new Auth0(getString(R.string.auth0_clientId), getString(R.string.auth0_domain));
this.lock = Lock.newBuilder(auth0, callback)
.build();
broadcastManager = LocalBroadcastManager.getInstance(this);
broadcastManager.registerReceiver(authenticationReceiver, new IntentFilter("com.auth0.android.lock.action.Authentication"));
startActivity(this.lock.newIntent(this));
}
</code></pre>
<p>I have following two questions:
1). First of all I don't understand why it needs callback though it doesn't callback even after authentication succeeded.
2). Shouldn't LocalBroadcastManager get response with UserProfile information instead of token information?</p>
<p>I'm using Lock version: com.auth0.android:lock:2.0.0-beta.2</p>
<p>Is there any better way to do it?</p>
<p>Thanks in advance!</p> | 2 |

Highcharts Error #13 : Rendering div not found | <p>I'm working with Javascript (Meteor) and trying to implement a Highchart with drilldown. After thoroughly testing the logic part for correctness, I've verified that the data passed onto my Highchart is correct. However, I am getting Error #13 because there seems to be a problem with how I am setting the "renderTo:" field within the "chart:" options in the chart, which currently looks like this:</p>
<pre><code>return chart = {
chart: {
renderTo: 'chart',
type: 'bar'
},
//other fields
</code></pre>
<p>In the HTML file, I use this template and invoke it in the body:</p>
<pre><code><template name= "myTemplate">
{{> highchartsHelper chartId="chart" chartWidth="100%" charHeight="100%" chartObject=topGenresChart}}
</template>

//other stuff
{{> myTemplate}}

Difference between web client and web service? | <p>Recently, I'm developing android app which must be connected to server (retrieve data from database and write data to database). Directly connecting app with database is obviously too risky (considering security) so I have been searching for another solution. To connect with database I have to use web service but I have found tutorial that uses web client and uri, "calls" PHP files on server and retrieves information with them. So, now I'm wondering what is the difference between this approach and web service. Are they both good solutions or one is better?</p>
<p>Thank you in advance.</p> | 2 |
Why run ASP.NET Core on .NET Core over .NET on Windows Server | <p>Ever since I heard about <code>ASP.NET Core</code> and <code>.NET Core</code> I have been wondering why you would want to develop an <code>ASP.NET Core web application</code> running on <code>.NET Core</code> over <code>.NET</code> if you are running a Windows server, like <code>Windows Server 2012</code>? I can understand that if you are developing for cross platform for something else like <code>Ubuntu</code> but if you are running a Windows server why would you want to develop going the <code>.NET Core</code> route?</p>
<p>What are the benefits (if any)? I feel like I am missing something here? Is it the ideal way to do <code>ASP.NET</code> web development and deployment going forward? When would you want to use the full <code>.NET</code> framework for <code>ASP.NET</code> web development instead of the <code>.NET Core</code> framework?</p>
<p>Not everyone is developing for cross platform? I have been developing for Windows servers all my life and have never needed to do anything cross platform. I don't think I will ever develop anything cross platform using .NET - I'll probably use something other than .NET (if I ever go this route).</p>
<p>I hope that someone can help clarify my confusion?</p> | 2 |

How can I get TypeScript to automatically infer the type of the result of a `yield` call? | <p>In the following code example:</p>
<pre><code>function* gen() {
let v = yield Promise.resolve(0);
return v;
}
</code></pre>
<p>The type of <code>v</code> is inferred to be <code>any</code>. I'm wondering if there's a way to get it to infer a different type (say, <code>number</code>) based on contextual clues.</p>
<p>I know that in this specific scenario I can use <code>async</code>/<code>await</code> instead, but I'm wondering about the general case (when not working with promises).</p> | 2 |
$(window).focus() not executed properly in Chrome | <p>I want to track clicks on AdSense elements on my page. To achieve that I put the focus on the window object and if it loses focus, I check if the mouse was in the area of the AdSense iFrame. Then i put the focus back on the window again. </p>
<p>This works. But in Chrome it works only once. So if I click on an adSense ad (opening in a new tab) and then I click on another one, the event doesn't fire anymore. </p>
<p>If I execute $(window).focus() in the console, the onBlur event fires again - but the $(window).focus() executed from within my code doesn't show any effect. I tried it with a Timeout too, without success. </p>
<p>Any ideas?</p>
<pre><code>trackElements("#contentAdSense, #fallbackAdSense, #sidebarAdSense");
function trackElements (elementsToTrack)
{
var isOverElement = false;
$(window).focus();
$(elementsToTrack).mouseenter(function(e){
isOverElement = e.currentTarget.id;
});
$(elementsToTrack).mouseleave(function(e){
isOverElement = false;
});
$(window).blur(function(e){
windowLostBlur();
});
function windowLostBlur ()
{
if (isOverElement)
{
console.log(isOverElement);
$(window).focus();
}
};

MaxPermSize vs MaxMetaspaceSize | <p>I am reading about the difference between PermGen and Metaspace and one of the disadvantages of the former is that there is a fixed size at startup. I do not understand why is it fixed if you have two parameters to tune it:</p>
<pre><code>-XX:PermSize
-XX:MaxPermSize
</code></pre>
<p>It seems to me that we can say the same about Metaspace, it is also fixed at startup by MaxMetspaceSize (I know that by default it is unlimited but it seems not a good practice to leave it as such).</p>
<p>Am I misunderstanding something? What is the difference between MaxPermSize and MaxMetaspaceSize ?</p> | 2 |
How to get and store parent table id into its child laravel | <p>I have searched alot to find a better way. I already read on <a href="https://laravel.com/docs/5.1/eloquent-relationships#one-to-many" rel="nofollow">Laravel docs</a> that </p>

Access First Firebase Node Data in Firebase Query | <p>I have a Firebase database query returning 100 child nodes. Then I put the nodes into a FirebaseRecyclerAdapter so the data is displayed on a recycler view. This is all working fine. Now I need to access the latest element and its Firebase key, but haven't been able to figure it out (should be easy, I must have missed something obvious). How do I get the latest element and its Firebase key in the returned query or adapter?</p>
<p>To get the 100 child nodes, I use:</p>
<pre><code>Query publishedPostsQuery = mFirebaseDatabase.child("posts").limitToFirst(100);
</code></pre>
<p>I then populate a Firebase recycler adapter:</p>
<pre><code>FirebaseRecyclerAdapter adapter = new FirebaseRecyclerAdapter<Post, PostViewHolder>(Post.class, R.layout.post_items, PostViewHolder.class, postsQuery) { ... };
</code></pre>
<p>This adapter is then used in a recycler view.</p>
<p>How do I get to the first Post object and its Firebase key through either Query or FirebaseRecyclerAdapter?</p>
<p>My firebase database structure looks like:</p>
<pre><code>-posts
-KLRDgtNht0iSB6RUGGz
- author: "author 1"
- title: "some post"
- detail: "blah blah"
-HGze53Sd4RRpFikdIKD
- author: "author 2"
- title: "great post"
- detail: "blah blah blah blah"
</code></pre>

compile 'com.google.firebase:firebase-database:9.0.2'

Getting Empty Response from Google Vision API | <p>I am testing some features of the Google Vision API and getting Empty response for images which I have clicked from my camera(5MP camera).

How to dynamically connect to databases in Sails.js | <p>I am rebuilding a legacy PHP application using nodejs and I choose sailsjs after about a week of exploration. Everything was fine until I realised that in sails you only have access to session variables in your controllers. Thus, I cannot make dynamic connections with the model. </p>
<p>The legacy app uses PHP session global variables to connect to different postgresql databases after authentication and I can't seem to find a work around on the web. I have seen similar questions on sails around the web. Any node/sails/database geeks around?</p>
<p>I am thinking of using sails for authentication since it already works and using expressjs to implement services that my sails app would then call by sending db connection params in some form of microservice architecture. </p>
<p>Currenttly running sails on localhost:1337 and my express on localhost:3000. Is this a good way to go about? </p> | 2 |
Load DB data(to Rest API) through postman | <p>We have been using postman for our Rest API testing but to make it more of an e2e data driven tool, we have a requirement to:

How do you create public extensions, in a shared framework, for XCTest? | <p>For example, I never use the description of <code>XCTestCase.expectation</code>, so I'd like to use a function to provide a default for it, and make it clear via naming that I'm initializing the expectation, as you can't really use an initializer for <code>XCTestExpectation</code>. But if the extension is not in a test target, then it can't compile:</p>
<blockquote>
<p>Cannot load underlying module for 'XCTest'</p>
</blockquote>
<pre><code>import XCTest
public extension XCTestCase {
func makeExpectation() -> XCTestExpectation {
return expectation(withDescription: "")
}
}

How to keep a session authenticated while crawling with scrapy? | <p>I have followed the response for this question (<a href="https://stackoverflow.com/questions/5851213/crawling-with-an-authenticated-session-in-scrapy">Crawling with an authenticated session in Scrapy</a>) to use scrapy with an authenticated session. The problem is that it seems to log in successfully, but when I make a request it seems to be unauthenticated.
Any idea on where the problem is?</p>
<p>Here is my python script:</p>
<pre><code>enter code here
import scrapy
from scrapy.spiders.init import InitSpider
from scrapy.utils.response import open_in_browser
class LoginSpider(InitSpider):
name = demo
login_page = #login page
inquery = #search query
start_urls = #urls with queries
def init_request(self):
return scrapy.Request(url=self.login_page, callback=self.login)
def login(self, response):
open_in_browser(response)
return [scrapy.FormRequest.from_response(response,
formid='login-form',
formdata={'username': 'username', 'password': 'password'},
callback=self.after_login)]
def after_login(self, response):
# check login succeed before going on
open_in_browser(response)
if "invalid username or password" in response.body:
self.log("Login failed", level=log.ERROR)
print "FAILED"
return
else:
self.log('authentication succeed')
return scrapy.Request(url=self.inquery, callback=self.parsse)
def parsse(self, response):
for result in response.xpath('//div[@class="span9"]/div[@class="search-result"]/div/a[@class="details"]/@href'):
print 'new resutl'
url = response.urljoin(result.extract())
yield scrapy.Request(url, callback=self.parse_details_contents)
def parse_details_contents(self, response):
item = ShodanItem()
for details in response.xpath('//ul[@class="services"]/li'):
item['ip'] = response.xpath('/html/body/div[3]/div/div[2]/div/div[1]/div/h2/text()').extract()
item['services_arr'][0] = details.xpath('/div[1]/div[1]/text()').extract()
item['services_arr'][1] = details.xpath('/div[1]/div[2]/text()').extract()
item['services_arr'][2] = details.xpath('/div[1]/div[3]/text()').extract()
item['services_arr'][3] = details.xpath('/div[2]/h3/text()').extract()
item['services_arr'][4] = details.xpath('/div[2]/pre/text()').extract()
print item['services_arr'][4]
yield item
</code></pre>
<p>Here is the log, I assume it does log in as it redirects to the main page, but afterwards, using the <code>open_in_browser()</code> command I get a page that asks for authentication in order to use the query:</p>

Responsive breadcrumbs with max crumb width | <p>I'm attempting to create a responsive breadcrumb trail where the overall trail width is restricted and each crumb width is also restricted. Additionally, I'd like to allow for the last crumb to take up any additional space. I've managed to put the following together that mostly demonstrates what I'm going for, but the JQuery solution is less than idea:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>$(document).ready(function() {
var $crumbs = $(".container .breadcrumb li");
var overallWidth = $(".container").width();
var crumbWidth = (100 / $crumbs.length) + '%';
$crumbs.css('max-width', crumbWidth);
var totalWidth = 0;
$crumbs.each(function(elt) {
var width = $(this).width();
totalWidth += width;
});
var adjustment = overallWidth - totalWidth;
var $lastCrumb = $(".container .breadcrumb li:last");
var lastCrumbWidth = $lastCrumb.width();
lastCrumbWidth = lastCrumbWidth + adjustment;
$lastCrumb.css('max-width', lastCrumbWidth - 25);
});</code></pre>
<pre class="snippet-code-css lang-css prettyprint-override"><code>.container {

</p>
<p>I'm sure this can be accomplished in a pure CSS way, but the solution is alluding me and probably beyond me.</p>
<p>Additionally, ideally this solution would also accommodate the hiding and showing of various elements via the "hidden" that are in the "optional" section.</p>
<p>UPDATE:
I've made some progress with the following, but it still isn't ideal since I'm blindly using a fixed max-width:</p>
<pre class="lang-css prettyprint-override"><code>.truncate {
max-width: 250px;
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
&:last-child {
max-width: 100%;

Login fails after changing password ASP.NET Core | <p>I'm using ASP.NET Core 1.0 and the identity stuff to authenticate and authorize the users. It all works fine except one single thing:</p>
<p>If the user resets or changes his password, he can't sign-in with the new credentials until the ASP.NET App is restarted. Means the new passwords are successfully saved in the database, but the Method <code>_signInManager.PasswordSignInAsync()</code> doesn't use the current data, but old one. It seems there is something like a cache in the EF Core or in the SignInManager/UserStore.</p>
<p>Sign-in after registration works also fine, it is just a problem after reset or change of the passwords.</p> | 2 |
How to learn android development efficiently? | <p>It's been around 1 month that I have started to work on Android to create an app, I understood the basics (Views, widgets, intent ...) and I use a lot developer.android.com to ancknowledge new things but when I try to do complex things, such as creating a camera preview inside my app, I feel like I am Ctrl+C and Ctrl+V the code that is provided without really understanding it. And most of the time my app crashes.</p>

Friendly ID not updating slug | <p>Using Rails 5 with Friendly ID 5.1.0</p>
<p>Trying to understand how to update the slug when a <code>Post</code> title is changed.</p>
<p>In the Friendly ID documentation it says you have to update the slug to <code>nil</code> before you can save your updated slug.</p>
<p>Example</p>
<pre><code>post = Post.first
post.title # "My first post"
post.slug = "my-first=post"
post.title = "My newer first post"
post.save!
post.slug # "my-first=post"
# Setting to nil first
post.slug = nil
post.title = "My newer first post"
post.save!
post.slug # "my-newer-first-post"
</code></pre>
<p>In my Post model I have set <code>should_generate_new_friendly_id?</code> in hopes it will update the slug without manually setting the slug to <code>nil</code> from the console or a web form.</p>
<pre><code># == Schema Information
#
# Table name: post
#
# id :integer not null, primary key
# title :string default(""), not null
# body :text default(""), not null
# created_at :datetime not null
# updated_at :datetime not null
# slug :string
#
# Indexes

class Post < ApplicationRecord
extend FriendlyId
friendly_id :title, use: :history
private
def should_generate_new_friendly_id?
title_changed? || super
end
end
</code></pre>
<p>Is it the job of the <code>should_generate_new_friendly_id?</code> method to update the slug if it's defined in your model?</p>
<p>Thanks again.</p> | 2 |

Matplotlib/Pandas: How to plot multiple scatterplots within different locations in the same plot? | <p>I often have two pandas dataframes, which I would like to plot within the same plot. Normally these are two samples, and I would like to contrast their properties, as an example: </p>
<p><a href="https://i.stack.imgur.com/IlOrO.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/IlOrO.png" alt="enter image description here"></a></p>
<p>The x axis simply has two locations, the left for the first dataset, and the right for the second dataset. </p>
<p>In matplotlib, one can plot multiple datasets within the same plot:</p>
<pre><code>import matplotlib.pyplot as plt
x = range(100)
y = range(100,200)
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax1.scatter(x[:4], y[:4], s=10, c='b', marker="s", label='first')
ax1.scatter(x[40:],y[40:], s=10, c='r', marker="o", label='second')
plt.show()
</code></pre>
<p><a href="https://i.stack.imgur.com/pGmmI.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pGmmI.png" alt="enter image description here"></a></p>
<p>However, </p>
<p>(1) How do you separate your datasets into two compartmentalized locations like the first example? </p>
<p>(2) How do you accomplish this with two pandas dataframes? Do you merge them and then specify two locations for plotting? </p> | 2 |
Highchart performance slow on plotting live data | <p>I am plotting live data in Highchart's(4.2.4) Line type chart for each second data i.e. 60 points for 1 min. and requirement is to collect each second data for long duration. I am using below code to add point in series. <strong>The number of series I have is 20</strong>. And for each series I have to add point per second. The <strong>turboThreshold set for each series is also around 2000</strong>. And <strong>slicing should be done after 1000 points</strong> data. </p>
<pre><code>chart.series[0].addPoint(point, false, data > 1000?shift: false, false);
</code></pre>
<p>I see a very low performance my browser keeps hanging and also chart is very irresponsive after some time. What can I do for better performance? I have tried below stuff:
1) Off the animation for series :</p>
<pre><code>plotOptions: {
series: {
animation:false,
states: {
hover: {
lineWidthPlus: 0
}
}
}
},
</code></pre>
<p>2) Turn off animation and redrawing on addpoint to the chart </p>
<p>3) Turn off markers for series</p>
<p>4) Included boost.js module in application
<pre> script src="https://code.highcharts.com/modules/boost.js"</pre> </p> | 2 |
Return value in Prolog | <p>I find that some 'functions' in Prolog return some value, like min/2 and max/2, etc, even though vast majority return only true or false. Are these called or grouped differently than boolean ones? Also how can one identify if they are returning a value other than going through documentation of each function. Can I find a list somewhere of functions which return some value? </p> | 2 |
Button to Add Cell with textField Text to Table Xcode/Swift 2.0 | <p>My question relates specifically to the following set of actions: I would like a user to be able to input text into a textField, press a button, then have that text transferred into a cell that is then newly populated in a table. </p>
<p>I have one view controller with a text field, button, and table objects. I also have an array that stores each string as the user enters the text, and my code looks as follows: </p>
<p>UPDATE 1: added "self.taskTable.delegate = self" and "self.taskTable.dataSource = self" as suggested in the comments. </p>
<p>UPDATE 2: forgot to add the identifier in the Storyboard editor, code is now functional, thank you everyone! The code is now as follows:</p>
<pre><code>import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet var textField: UITextField!
@IBOutlet var taskTable: UITableView!
var taskArray : NSMutableArray! = NSMutableArray() //Could be a non-NS as well
@IBAction func addTask(sender: AnyObject) {
//Print to alert we entered method
print("task submitted")
//Get input from text field
let input = textField.text
//Add object to array, reload table
self.taskArray.addObject(input!)
self.taskTable.reloadData()
}//addTask
override func viewDidLoad() {
super.viewDidLoad()
self.taskTable.delegate = self
self.taskTable.dataSource = self
print("application finished loading")
// Do any additional setup after loading the view, typically from a nib.
}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.taskArray.count;

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell:UITableViewCell = self.taskTable.dequeueReusableCellWithIdentifier("cell")!
cell.textLabel?.text = self.taskArray.objectAtIndex(indexPath.row) as? String
return cell

Testing aiohttp & mongo with pytest | <p>I have a simple coroutine <code>register</code> that accepts login and password
as post arguments, then it goes into the database and so on.
The problem I have is that I do not know how to test the coroutine.</p>
<p>I followed examples from
<a href="https://aiohttp.readthedocs.io/en/latest/testing.html" rel="nofollow">https://aiohttp.readthedocs.io/en/latest/testing.html</a>.</p>
<p>And everything seemed easy until I started writing tests myself.</p>
<p>Code for <code>test_register.py</code></p>
<pre><code>from main import make_app
pytest_plugins = 'aiohttp.pytest_plugin'
@pytest.fixture
def cli(loop, test_client):
return loop.run_until_complete(test_client(make_app))
async def test_register(cli):
resp = await cli.post('/register', data={'login': 'emil', 'password': 'qwerty'})
assert resp.status == 200
text = await resp.text()
</code></pre>
<p>And <code>register.py</code></p>
<pre><code>from settings import db
async def register(request):
post_data = await request.post()
print('Gotta: ', post_data)
login, password = post_data['login'], post_data['password']

<p><code>main.py</code></p>
<pre><code>from aiohttp import web
from routes import routes

<p>And then I ran <code>py.test test_register.py</code> and it got stuck on database operation
<code>matches = await db.users.find({'login': login}).count()</code></p> | 2 |
Get current post ID in javascript - WordPress | <p>I am making a plugin for wordpress. The plugin will add a tinymce on the edit post, and it will send the post_id to the database to do some identification later.</p>
<p>In my case, I am writing a javascript, which directory in <code>wordpress\wp-content\plugins\facebook-api\js\shortcode-tinymce-button.js</code>. And now I have no idea how I can get the post_Id in javascript.</p>
<p>Here is what I am doing:</p>
<ol>
<li>user click the <code>OK button</code> will send the post_Id and the text box value to the database.

How to examine user thread call stack from windbg kernel debugger? | <p>My exe-once test program calls <code>CancelIo</code> and it blocks, I'd like to investigate in which function it is blocking, so, when it blocks, I use windbg to break into the machine, remotely, and try to find it out.</p>

Is there a way to validate an SMTP configuration using Zend-Mail? | <p>I have been working on a class in PHP to send out mail and I decided to use the Zend framework. This class sends out mail using a user's SMTP configuration. As of right now I am checking a user's SMTP configuration by using the supplied user credentials, and sending out a "dummy" email to a "dummy" email address, and catching the <code>ZendException</code> class that may be thrown on error. This is a horrible method, because of many reasons:</p>
<ul>
<li>The SMTP user get's banned eventually for suspected "Spamming" (GMail)</li>
<li>Inefficient and time consuming</li>
<li>Failed email delivery attempt is in user's mailbox</li>
</ul>
<p><strong>The following is an example of what I am doing right now to test if a SMTP configuration is valid:</strong></p>
<pre><code>public function validSMTP () {
// Get the user's SMTP configuration
$config = $this->getConfiguration ();
// Create a new Zend transport SMTP object
$transport = new Zend_Mail_Transport_Smtp ( $config ["hostname"], [
"auth" => "login",
"ssl" => $config ["protocol"],
"port" => $config ["port"],
"username" => $config ["from"],
"password" => $config ["password"]
]);
// Create a new message and send it to dummy email
$mail = new Zend_Mail ("UTF-8");
$mail->setBodyText ( "null" );
$mail->setFrom ( $config ["from"] );
$mail->addTo ( "[email protected]" );
$mail->setSubject ( "Test" );
// Attempt to send the email
try {
// Send the email out
$mail->send ( $transport );
// If all is well, return true
return true;
}
// Catch all Zend exceptions
catch ( Zend_Exception $exception ) {
// Invalid configuration
return false;
}
}
</code></pre>
<p>So my question is: Is there a better way of doing this? Does <strong>Zend_Mail</strong> have a built in feature like this? I have looked all over and couldn't find anything build-in into <strong>Zend_Mail</strong>. Thank you in advance to whoever answers!</p> | 2 |

Jenkins pipeline, bitbucket hook and maven release plugin infinite loop | <p>I haven't been able to find any info about this, so i hope you guys can help me on this one</p>
<p>I've a maven project hosted in bitbucket that has a BitBucket WebHook pointing to someurl/bitbucket-hook/ , this hooks triggers the build of my project that is defined by a pipeline that has this structure:</p>
<pre><code>node {
stage 'Checkout'
git url: 'https:...'
def mvnHome = tool 'M3'
#Various stages here
...
stage 'Release'
sh "${mvnHome}/bin/mvn -B clean install release:prepare release:perform release:clean"
}
</code></pre>
<p>the problem is that maven release plugin pushes changes to BitBucket, and this triggers again the jenkins script, making an infinite loop of builds, is there a way to prevent this? </p>

Dashboard tool for a custom SQL Server database | <p>For a project I'm working on I have build a reporting database in SQL Server. We are pretty much free to design the structure of the DB and what we put it in.</p>
<p>However, now comes the fun part and we would need to be able to visualize the data in some nice dashboards.</p>
<p>Can anybody provide me with some suggestions on an easy to use tool (end-users will need to be able to manipulate the dashboards) that is not dependent on the underlying database technology? (if its based on SQL Server I can live with that :))</p>
<p>I've looked in to Kibana but seems to be only possible if you use ElasticSearch.
Currently investigating Grafana to see what that brings me so anything in that realm would be appreciated!</p> | 2 |
Find out query text before doing ExecuteNonQuery() | <p>Here is an example of using OleDbCommand and ExecuteNonQuery(I took it from a manual on msdn.microsoft.com). I would like to check out the query that was generated before executing it.</p>

command.Connection = connection;
command.CommandText =
"INSERT INTO dbo.Region (RegionID, RegionDescription) VALUES (?, ?)";
command.Parameters.Add("RegionID", OleDbType.Integer, 4);
command.Parameters.Add("RegionDescription", OleDbType.VarWChar, 50);
command.Parameters[0].Value = 20;
command.Parameters[1].Value = "First Region";
// Call Prepare and ExecuteNonQuery.
command.Prepare();

<p><b>find out the query that is being executed here</b></p>

// Change parameter values and call ExecuteNonQuery.
command.Parameters[0].Value = 21;
command.Parameters[1].Value = "SecondRegion";
command.ExecuteNonQuery();
}
}
</code></pre>
<p>Is there any possible way to do it? I'm using PgSqlCommand - which is PostgreSQL equivalent of OleDbCommand and getting undescribed exception. I was able to build that query and find what was the error by cycling Command.Parameters and replacing question symbols in Command.CommandText with paremeter's values, but I am hoping that there is a built-in method to get that query. </p> | 2 |

<p>None of this did anything to help, my chart labels are still reading from 1 to 10001, and no matter how much I zoom in (with added zoom controls) the labels still read on every interval ending with 1. Like 1001, 2001, 3001, .. etc. </p>
<p>How can I change this to read from 0 to 10000? And only show lines and labels on intervals ending with 0</p>
<p>Thanks</p>
<p>EDIT:</p>
<p>The minimum and the maximum were already set, in the screenshot you see below, all the X values are correctly indexed, but for some reason the chart display value 10001</p>
<p>And I do not wish to set the value to the Maximum to 10000 in this case, it will prevent the label from showing up but it will also prevent the ability to scroll the axis past the last measurement.</p>

<p>At home it works, but at work it seems I might need some type of pemissions elevated. I have tried running VS as administrator and changing the port to 8733 but I still get the problem. Also in command promopt I tried "netsh http add urlacl url=<a href="http://+:8080/MyUri" rel="nofollow">http://+:8080/MyUri</a> user=DOMAIN\user", but got the error "url reservation add failed error 5" I'm thinking maybe admin needs to elevate some type of permission.</p>

TeamCity Agents 64-bit fail to start | <p>I am trying to get the 64-bit version of a TeamCity (9.1.1) agent running. I can install the service, but as soon as I start it, I get the following in the wrapper.log:</p>
<pre><code>ERROR | wrapper | .... | Stdout pipe creation failed
ERROR | wrapper | .... | The TeamCity Build Agent service was launched, but failed to start.
</code></pre>
<p>I can't find any other log entries providing info regarding this.</p>
<p>Any suggestions? I literally only found two similar posts online, which makes me think it is more related to the Java service wrapper than TeamCity...</p>
<p>(Update: The 64-bit version is required to execute tests specific to a 64-bit version of a built assembly)</p> | 2 |
Removing empty key from RDD | <p>I am reading a text file and implementing a word count example. The problem is I am getting an RDD with empty Key.</p>
<p>Here is code:</p>
<pre><code>val tokens = sc.textFile("test.txt").flatMap(line => line.split(",")).map(_.trim)
val tableForFrequency = tokens.map(word => (word, 1))
.reduceByKey((a, b) => a + b)
tableForFrequency.saveAsTextFile("file.txt")
</code></pre>
<p>I am not sure why I am getting an empty and how do I remove it.</p>
<p>Please note: I am a newbie in Scala/Spark and have already looked for related question before posting this one.</p> | 2 |
RXSwift flatMap two methods | <p>I'm having 2 methods like this:</p>
<pre><code>func rxGetAllTonicsForLanguage(language: Language) -> Observable<AnyObject?>
func saveTonics(list: [Tonic]) -> Observable<AnyObject?>
</code></pre>
<p>Now I want to first do the getAllTonics call and then with the result of that call I want to do the next action. So I thought this was something I could do with FlatMap. But I'm stuck I can't figure out how to chain these.</p>
<p>I tried like follows:</p>
<pre><code> self.remoteService.rxGetAllTonicsForLanguage(language)
.subscribeOn(ConcurrentDispatchQueueScheduler(globalConcurrentQueueQOS: .Background))
.flatMap{tonics -> Observable<[Tonic]> in
print("Tonics: \(tonics)")
let x = tonics as! [Tonic]
return TonicAdapter.sharedInstance.saveTonics(x)
}.observeOn(MainScheduler.instance)
.subscribe({ e in
switch e {
case .Next(let element):
if let result = element as? String {
DDLogDebug("Saved something \(result)")
}
case .Error(let e):
DDLogError("Error in save tonics \(e)")
case .Completed:
DDLogDebug("Completed save tonics")
}
}
).addDisposableTo(self.disposeBag)
</code></pre>
<p>It gives me this error on the line of return TonicAdapter:</p>
<pre><code>Cannot convert return expression of type 'Observable<AnyObject?>' (aka 'Observable<Optional<AnyObject>>') to return type 'Observable<[Tonic]>' (aka 'Observable<Array<Tonic>>')
</code></pre>
<p>I don't see the problem because both methods are returning Observables?</p> | 2 |
how to align to right and middle in height in layout | <p>I have a Switch, witch is aligned to the left of a layout,
I want to align a TextView to the right of it AND to the middle of the height of it.
