wso2 APIManager: Add PingIdentity as new OAuth-Endpoint | <p>We are planing to use PingFederate-Server as our central identity managment solution. What are the steps to integrate the ping server oauth-endpoint to our wso2 landscape.
Is there already a solution available?</p>
<p>I read the blog-post <a href="https://amilasnotes.wordpress.com/2015/05/19/integrating-with-a-third-party-oauth-provider-overview" rel="nofollow">https://amilasnotes.wordpress.com/2015/05/19/integrating-with-a-third-party-oauth-provider-overview</a> and it looks like that this task is possible.</p>
<p>Has someone experienced replacing the internal wso2 key-manager?</p>
<p>And is it possible to use both keymanagement solution (interal and ping), so that we don't need to migrate the current applications/access-tokens?</p>
<p>Thx, in advance

Can not update a system app | <p>I have a application preloaded on ROM, and put it on system app. Current version code is 3. This apk also published on Google Play.</p>
<p>Note : All cases below I use same key store, same package with the apk preloaded on ROM.</p>
<p><strong>* From Android Studio, I build a new version and upgrade version code to 4.</strong></p>
<p><strong>Case 1:</strong></p>
<p>I copy this apk to phone and install manually. Phone display "Can not install". I check the log and it show :</p>
<p><em>"W/PackageManager: Package xxx signatures do not match the previously installed version; ignoring!"</em></p>
<p><strong>Case 2:</strong></p>
<p>I uploaded the new apk to Google Play. Google Play accept it normally. After Google approved and published the app, I open Google Play app , find my app and check the status. It displayed "UnInstalled" and "Open".( It should display "Update" but it did not).</p>
<p>Right now I can not update my application. Can anybody tell me what is the reason for this case?</p> | 3 |

Facebook Ads Insights API System user and data fetching automation | <p>I'm going to use Facebook Ads Insights API to fetch stats about campaigns (read_insights permission) and load them into my app.</p>
<p>I don't want the user of my app to need to login through facebook. However, it appears that the process of getting System user is rather complicated, and even requires to produce a screencast of the user logging in (which is exactly what I don't want to implement).</p>
<p>Do I really need to go through all these steps to get basic/standard API access levels?
Is this the only way of generating a System user? Or of automating campaign stat fetching?</p> | 3 |
Error in file(file, “rt”) : cannot open the connection | <p>I'm new to R, and after researching this error extensively, I'm still not able to find a solution for it. Here's the code. I've checked my working directory, and made sure the files are in the right directory. Appreciate it. Thanks</p>
<pre><code>**pollutantmean <- function(id, directory, ...){
x <- c(NA)
for(i in id){
csvfile <- sprintf("%03d.csv", i)
filepath<- file.path(directory,csvfile)
foo <- read.csv(filepath, ...)
x <- x+foo
}
mean(x,na.rm=TRUE)
}**
</code></pre>
<p>OK, and then ,I type the code like this:</p>
<p><strong>pollutantmean(1:10,"specdata","sulfate")</strong></p>
<p>Then, I got a trackback:</p>
<p>*Error in file(file, "rt") : cannot open the connection</p>
<p>In addition: Warning message:
In file(file, "rt") :
cannot open file 'specdata/001.csv': No such file or directory*</p>
<p>I'm confused, how should I solve this problem?</p> | 3 |

I want to create Revit Plugin and in that the command class will be generic | <pre><code>[Transaction(TransactionMode.Manual)]

<p>The command.cs file looks like shown above. If I write class as
class InteropCommand then I need to change the .Addin file accordingly otherwise the command will not work. Now I have question that how can I write a command class in such a way that it will load the Revit addin command. In current scenario I am not able to load the Revit command. </p>
<p>My .Addin file look like below. Do you have any idea how to tackle with this kind of problem ? </p>

using submodules in git for the timid | <p>I am working in a project which have few layers, each of them independent sub-projects. </p>
<p>It looks like this:</p>
<pre><code>[ Project C ] [ Project D ] C and D uses B and therefore A
[ Project B ] B has all source code in a and adds more
[ Project A ]
</code></pre>
<p>Setting upstream to the parent repository and issuing <code>git pull upstream</code> works well to get the changes from the upper project.</p>
<p>However, how would I push a commit in the scenario of bug fix in C which affects the code shared with the parent layers? </p>
<p>If I issue <code>git pull project-D</code> from Project A, it will also merge all the source code added at that layer.</p>
<p>I also considered using <code>sub-trees</code> or <code>submodules</code>, but it still looks complicated.</p> | 3 |
How can I bulk publish 11,500 coupon codes in WooCommerce Smart Coupons? | <p>We are running a deal with Groupon and have used Smart Coupons plugin with WooCommerce to import 11,500 Groupon codes. I now need to activate them (aka plublish.) However, currently in the WooCommerce interface you can only select and publish 20 coupon codes at once. This would take ~7.5 hours to publish all codes. Does anyone know of a way to easily activate all 11,500 codes at once? </p> | 3 |
What versioning strategies are available to SignalR hubs with .NET clients? | <p>WCF offers rich support for versioning services, contracts, clients etc. I'm investigating SignalR as a way for my deployed .NET clients to talk to the server, but have not found any resources mentioning how to evolve hubs and clients independently. Is there a reason for this? Surely there must be some kind of recommended best-practice for handling hub evolution (adding methods, changing parameters in existing methods, removing operations, etc) when you don't necessarily have control over client versions. </p> | 3 |

Fit a Vertical UISlider into an Existing Container View? | <p>I want to create a vertical <code>UISlider</code> and exactly fit it into an existing container view that is sized and placed from a <code>.xib</code> file using <code>autoLayout</code>. But I simply cannot get it to work and I have Googled my fingers bloody.</p>
<p>The closest I have gotten creates a slider that is too long and extends off the screen.</p>
<p>Am I putting the code in the wrong place?</p>
<p>I am putting my code in <code>"layOutSubviews"</code>
Some Points of interest:</p>
<p>1.Per Apple's docs, the view's "frame" is not valid after the transformation and should not be set.</p>
<p>2.The frame of the slider is set to the future parent's dimensions <em>before</em> the transformation (with x and y swapped).</p>
<p>3.The transformed view appears to maintain its bounds in the pre-transformation coordinate frame. i.e. After the 90 degree transformation, the width and height of the transformed view's bounds appear to be swapped.</p>
<p>This code doesn't work. The slider looks right except that it extends off the bottom of the screen. The slider bounds and even the frame (which Apple says is not valid) seem to match the bounds and frame of the container view. The slider doesn't even stay within its own bounds.</p>
<pre><code>[super layoutSubviews];
CGRect trigLevelSliderFrame=self.trigLevelSliderContainer.bounds;
trigLevelSliderFrame.size.height=self.trigLevelSliderContainer.bounds.size.width;
trigLevelSliderFrame.size.width=self.trigLevelSliderContainer.bounds.size.height;
UISlider *mySlider=[[UISlider alloc] initWithFrame:trigLevelSliderFrame];
self.trigSlider=mySlider;
[mySlider release];
self.trigSlider.transform=CGAffineTransformMakeRotation(-M_PI_2);
CGPoint center=CGPointMake(self.trigLevelSliderContainer.bounds.size.width/2,self.trigLevelSliderContainer.bounds.size.height/2);
self.trigSlider.center=center;
[self.trigLevelSliderContainer addSubview:self.trigSlider];

Drawing a shape | <p>I'm trying to draw an E shaped thingy and as far as I know there are 2 ways to go one of them being path.</p>

<p>Or I could create a rectangle with a UIView and carve it with 2 small squares and make an E by substracting those 2 spots.</p>
<p>I'm not sure which way is the way to go considering efficiency and everything. If there's any other better ways, please enlighten me. Thanks!</p>
<p>(I've found plenty about drawing shapes on here but none is even remotely recent and I'd like a recent answer)</p> | 3 |

Chef - restarting due to auto-encryption mechanism | <p>We have an issue with Chef in that it restarts unnecessarily. We schedule chef-client to run every 1 5 minutes. However, a restart of processes and the app occurs every time, even when the user has not made changes.</p>
<p>The reason for this is we have a proprietary app we are automating that has a mechanism whereby it encrypts a plain text password in a config file, so every time chef runs, it sees a difference in the config file it generates from the template (unencrypted string), and the currently deployed config file (that this app has touched after chef and encrypted the text).</p>
<p>The app team does touch this file frequently in other places so ignoring that file completely is not ideal. However, looking for options from others who may have faced the same issue.</p>
<p>Thanks in advance.</p> | 3 |

Retaining category order when charting/plotting ordered categorical Series | <p>Consider the following categorical <code>pd.Series</code>:</p>

Out[38]:
0 good
1 good
2 ok
3 bad
4 bad
5 awful
6 awful
dtype: category
Categories (4, object): [bad < ok < good < awful]
</code></pre>
<p>I want to draw a pie or bar chart of these. According to <a href="https://stackoverflow.com/a/31029857/2071807">this SO answer</a>, plotting categorical <code>Series</code> requires me to plot the <code>value_counts</code>, but this does not retain the categorical ordering:</p>
<pre><code>df.value_counts().plot.bar()
</code></pre>
<p>How can I plot an ordered categorical variable and retain the ordering?

Clicking on button_to is not taking me to the intended method | <p>I am trying to get a button_to to call a controller. I've tried a number of variations and nothing seems to work. </p>
<p>In my index.html.erb, I have</p>
<pre><code> <%= button_to "Clear Search", { :controller => 'documents', :action => 'reset_search'} %>

<p>In my documents controller, I have </p>
<pre><code> helper_method :reset_search
def reset_search
@documents = Document.all
$search = nil
params[:search] = nil
redirect_to documents_path
$temp2 = 'testing 1 2 3'
end
</code></pre>
<p>On the index, I put the following at the bottom. </p>
<pre><code>$temp2 <%= $temp2 %>

Target div once user has finished dragging element | <p>I have a list:</p>

<div class="done" style="display:none;">
Yay!

<p>And it is draggable via:</p>
<pre><code>var el = document.querySelectorAll('.draggable');
for (var i=0;i<el.length; i++) {
var sortable = Sortable.create(el[i], {
handle: '.drag',
animation: 150,
onUpdate: function (evt/**Event*/){
var item = evt.item; // the current dragged HTMLElement
// show .done here

}
</code></pre>
<p>Test <a href="https://jsfiddle.net/h2qnucpg/7/" rel="nofollow">jsFiddle</a>. </p>
<p>My question is, how do I show the <code>.done</code> div once the user has dragged an item?</p>

<pre><code>jQuery(this).parent().parent().next().show();

Qt 5.5 - Windows API not Working as usual | <p>I am using <strong>Qt 5.5</strong> on <strong>Windows 10</strong> and I want to open a <code>QWidget</code> in <strong>Foreground</strong> and want to <strong>focus</strong> the <code>LineEdit</code>, like RUN (WIN + R) on Windows. The Problem is the Application is running in the background and I have only an keylogger to register a shortcut (LCTRL + LWIN + T) to toggle the window (show + focus / hidden). </p>
<p>If the shortcut is pressed, I execute following Code:</p>
<pre><code> if(this->isHidden()){
this->show();
//Windows API Methods:
SetActiveWindow((HWND) this->winId());
SetForegroundWindow((HWND) this->winId());
SetFocus((HWND) this->winId());
this->_edit->setFocus();
qDebug() << "[OUT][DONT WORKING] Window shoud be shown and focused";
}else{
this->hide();
qDebug() << "[OUT][WORKING] Window shoud be hidden";
}
</code></pre>
<p>If I now press <strong>LCTRL + LWIN + T</strong>, it opens the Window in the background and that's not what I want. Can someone explain why this does not work? What can I do that the window opens in the foreground and the text box is <strong>focused</strong>? And I don't want to set the flag <code>StayAlwaysOnTop</code>, because then the text field is still not focused. </p>
<p>I hope you can help me.
Thank you very very much!</p> | 3 |

DXT Texture working despite S3TC not being supported | <p>The topic involves OpenGL ES 2.0.</p>
<p>I have a device that when queried on the extensions via </p>
<pre><code>glGetString(GL_EXTENSIONS)
</code></pre>
<p>Returns a list of supported extensions, none of which is <code>GL_EXT_texture_compression_s3tc</code> .</p>
<p>AFAIK , not haveing <code>GL_EXT_texture_compression_s3tc</code> shouldn't allow using DXT compressed textures.</p>
<p>However, when DXT compressed texture are used on the device , they render without any problems.</p>
<p>Texture data is commited using <code>glCompressedTexImage2D</code> .</p>
<p>Tried for DXT1 , DXT3 and DXT5 .</p>
<p>Why does it work ? Is it safe to use a texture compression although the compression seems to not be supported ?</p> | 3 |
Click listener of button inside a layout view that is bind with click listener is not working in Android | <p>I am developing an Android app. In my app, I have a button inside a layout view. Layout view is set click listener. Button inside layout is also bind with click listener. But when I click button inside layout, both listeners are not working. But when I click layout view avoiding button, listener of layout view is working.</p>
<p>For example, this is my layout file</p>
<pre><code><LinearLayout>
<LinearLayout
android:id="@+id/child_container"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:focusable="false"
android:focusableInTouchMode="false"
android:text="LIKE"
android:id="@+id/btn_click"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>
</code></pre>
<p>This is example of onCreate event of my activity</p>
<pre><code>childContainer.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//this is working
}
});
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//This is not working
}
});
</code></pre>
<p>As you can see I set <code>android:focusable="false"</code> and <code>android:focusableInTouchMode="false"</code> to button in layout file. But click listener of button is not working. How can I fix that?</p> | 3 |

Windows7: getaddrinfo returning "No such host is known" for [::1] | <p>I'm working on modifications to my code to support dual stack environments on Windows 7 et. al. The code uses ActiveMQ-CPP (3.8.4). I've set this up to use a connection to the broker on URI "tcp://[::1]:61616". I've already found I need to compile APR with APR_HAVE_IPV6. </p>
<p>Now the issue. When APR's call_resolver() method calls getaddrinfo() with the hostname "[::1]", it returns "No such host is known" (code 11001). </p>
<p>I can ping [::1] without an issue. I've tried uncommenting the ::1 entry in hostnames. I've added the Internet Protocol Version 6 checkbox on my interfaces.</p>
<p>Any ideas what I'm missing?</p> | 3 |
T-SQL Finding VarChar String with Wildcards, but Carriage Return in Field Produces Fewer Results | <p>I'm trying to find all rows with a specific variable character alpha-numeric string from a variable character field using the following code:</p>
<pre><code>SELECT *
FROM Table AS t
WHERE t.Textfield LIKE '%abc123abc%' OR t.Textfield LIKE '%aabbcc12345abcde%';
</code></pre>
<p>However, not all of the rows are being returned. I figured out that the rows which were not being returned from my query aren't showing up because of a carriage return after the final character of the alpha-numeric string I'm looking for.</p>
<p>My question is what can I do to make sure all of the rows return for my query instead of just the rows not having a carriage return at the end of my variable character alpha-numeric string?</p>
<p>Thanks.</p> | 3 |

Prevent double booking ASP.NET C# | <p>I 'am trying to create a vacation planner in asp.net with a SQL Server Express database.</p>
<p>When you add a vacation, you have to add a <code>begintime</code>, <code>endtime</code> and of course who you are.</p>

--------------
A | 90%
B | 50%
C | 25%

Streaming video using fork does not return content | <p>I've experienced some sort of timeout when I try to request the same video stream twice, therefor I thought a fork could solve my problem.</p>
<p>Before I start, I'm using a <a href="https://gist.github.com/ranacseruet/9826293" rel="nofollow">third party class for video streams</a>. Using my own routing system this works, but I have the problem stated above.</p>

$video = c_video_folder . $req->get_param('id') . '.mp4';
if (file_exists($video)) {
$res->videoStream($video);
} else {
$res->failure(204); // no content
}
}

<p>After trying to use a fork, it looks like this:</p>
<pre><code>public function stream ($req, $res) {
$video = c_video_folder . $req->get_param('id') . '.mp4';
if (file_exists($video)) {
$pid = pcntl_fork();
if ($pid == -1) {
$res->videoStream($video);
} else { //async
$res->videoStream($video);
}
} else {
$res->failure(204); // no content
}
}
</code></pre>
<p>The problem that occur is the response package contains no data, except the correct headers and such. Does anyone know why this happens?</p>
<p>PS. the parameter $res, is simply another class setting headers and then calling the VideoStream class linked in the top.</p> | 3 |

Why does byte representation in Java store data in decimal? | <p>I was debugging a problem where I created a byte array from binary representation of strings such as below. </p>
<ol>
<li>While debugging the array just to see how it is stored, I could see them stored internally as decimals. Why is that? </li>

Shell Script from Unix not running on other OS | <p>I have a shell script working on SCO Unix 5.0.6. The problem is when I copy the script to another machine with SCO Unix 5.0.7 (and also other OS) then it is not running. It shows a syntax error. </p>
<p>Note that when I copy all instructions and paste them in command line then they work perfectly. However, as I said they are not working as one script file. </p>
<p>As example in the script I have:</p>
<pre><code>case "${MODUS}" in
</code></pre>
<p>And I get the below error:</p>
<pre><code>syntax error near unexpected token '$'in\r''
</code></pre>
<p>Base on the error it seems to me something is added at the end of each instruction. </p>
<p>In some cases when the error is at the end of the instruction I can fix the problem. I add a space and #(to consider the rest line as comment) at the end of each instruction. Then it works. However, the problem is that I cannot do that for all instructions. In some cases the error is in middle of the instruction and then (space#) not working. </p>
<p>Please let me know what is the reason for the error and how can I fix that.</p> | 3 |
How to configure ruby Neo4j ActiveRel object to get cascading persistance | <p>I experiment with Neo4j gem for working with Neo4j library. When you configure active nodes without using active relationships you can specify :origin property and on node.save it cascades through all graph saving everything auto-magically. Now I want to use active relationships to have some data on them and :origin is not allowed anymore on node relationship declaration and on node.save it doesn't propagate changes anymore.</p>
<p>Is there a way to achieve 'single node.save call - store all graph' functionality?</p>
<p>My problem is that the performance went down when I have to create each relationship separately, so maybe there is another way to batch the queries?</p>

<p>For some reason, this doesn't seem to be working on my system. I tracked it down to the fact <code>egrep</code> was returning successfully for searches on the empty string, e.g. this will print <code>0</code>:</p>
<pre><code>echo '' | egrep -q -- '-?|-h|--help'
echo $?
</code></pre>
<p>Why does this happen, and what can I do to fix it? Thanks!</p>
<hr>
<p><strong>edit:</strong> Also just noticed that while this command will succeed:</p>
<pre><code>echo -h | egrep -- -?
echo $? # 0
</code></pre>
<p>Using it with regular <code>grep</code> will fail:</p>
<pre><code>echo -h | grep -- -?
echo $? # 1
</code></pre>
<p>I'm assuming the extended grep is treating <code>?</code> as a special character, then?</p> | 3 |
gvisGeoChart Not Recognizing Lat/Long for Marker | <p>I'm having issues running some code to plot markers on a US map using <code>googleVis</code> and <code>gvisGeoChart()</code>. I can run the following example, no problems:</p>
<pre><code>require(datasets)
library(googleVis)
GeoMarker <- gvisGeoChart(Andrew, "LatLong",
sizevar='Speed_kt',
colorvar="Pressure_mb",
options=list(region="US"))
plot(GeoMarker)
</code></pre>
<p>Here is the kind of code I'm using. I'm attempting to bring lists of values into a data frame and then use this data to plot markers on a US map.</p>
<pre><code>library(googleVis)
library(ggmap)
cities <- c("Norman, OK", "Madison, WI", "Tallahassee, FL")
test <- as.data.frame(cities)
test$rank <- c(2,1,3)
colnames(test) <- c("City","Rank")
geocodes <- geocode(as.character(test$City))
new <- data.frame(test[,1:2],geocodes)
TestPlot <- gvisGeoChart(new, sizevar='Rank',options=list(region="US"))
plot(TestPlot)
</code></pre>
<p>I then receive the following error: </p>
<p><code>Error in data.frame(Latitude = numeric(0), Longitude = numeric(0), Rank = c(2, : arguments imply differing number of rows: 0, 3</code></p>
<p>I have searched and can't find too many tutorials on using <code>googleVis</code> in R and especially with regards to gvisGeoChart apart from the documentation. I've inspected the <code>Andrew</code> data frame and used <code>str()</code> and can't find anything different between the two data sets. </p>
<p>Thanks for any and all help and please let me know if you need any clarification!</p> | 3 |

In java how can i randomize and int in an array | <p>Hi i am just learning java and want to write a sort of vocabulary trainer. It is working but i want to give the questions in a random order. The trainer pics a list from an external file and splits the file in two parts. It is asking as long the next line isn't null.</p>
<pre><code>for (int i = 0; (zeile = br.readLine()) != null; i++) {
splitted = zeile.split(";");
eng[i] = splitted[0];
ger[i] = splitted[1];
</code></pre>
<p>then i am asking for the vocabulary. But as you can see its always in the same order. I don't know how i can correctly randomize the list before the asking part.</p>
<pre><code>for (int j = 0; j < eng.length; j++) {
correct = false;
while (!correct) {
System.out.print(eng[j] + " bedeutet: ");
gerEingabe = vokabel.nextLine();
if (gerEingabe.equals(ger[j])) {
System.out.println("Das ist Korrekt. Auf zur nächsten Aufgabe.");
correct = true;
} else {
System.out.println("Das war leider Falsch. Bitte versuche es noch ein mal.");

How can I handle the deletion of these items from SharedPreferences? | <p>I'm building an app that will silence people's ringers based on their location. I use a PlacePicker API, then save the name of the place to SharedPreferences and add it to a ListView. I have problems with deleting the items, though. When the user long clicks a listview item, it is supposed to be deleted from SharedPreferences. The problem is, after the first deletion, my method of referring to which SharedPrefs item to delete is bad and it doesn't work. How can I fix it?</p>

How to sort python lists due to certain criteria | <p>I would like to sort a list or an array using python to achive the following:
Say my initial list is:</p>
<pre><code>example_list = ["retg_1_gertg","fsvs_1_vs","vrtv_2_srtv","srtv_2_bzt","wft_3_btb","tvsrt_3_rtbbrz"]
</code></pre>
<p>I would like to get all the elements that have 1 behind the first underscore together in one list and the ones that have 2 together in one list and so on. So the result should be:</p>
<pre><code>sorted_list = [["retg_1_gertg","fsvs_1_vs"],["vrtv_2_srtv","srtv_2_bzt"],["wft_3_btb","tvsrt_3_rtbbrz"]]
</code></pre>
<p>My code:</p>
<pre><code>import numpy as np
import string
example_list = ["retg_1_gertg","fsvs_1_vs","vrtv_2_srtv","srtv_2_bzt","wft_3_btb","tvsrt_3_rtbbrz"]
def sort_list(imagelist):
# get number of wafers
waferlist = []
for image in imagelist:
wafer_id = string.split(image,"_")[1]
waferlist.append(wafer_id)
waferlist = set(waferlist)
waferlist = list(waferlist)
number_of_wafers = len(waferlist)
# create list
sorted_list = []
for i in range(number_of_wafers):
sorted_list.append([])
for i in range(number_of_wafers):
wafer_id = waferlist[i]
for image in imagelist:
if string.split(image,"_")[1] == wafer_id:
sorted_list[i].append(image)
return sorted_list
sorted_list = sort_list(example_list)
</code></pre>
<p>works but it is really awkward and it involves many for loops that slow down everything if the lists are large.</p>
<p>Is there any more elegant way using numpy or anything?</p>
<p>Help is appreciated. Thanks.</p> | 3 |

Replacing values in each column independently according to value order in R | <p>I have a matrix:</p>
<pre><code>mat <-structure(c(0.35, 0.27, 0.26, 0.28, 0.23, 0.37, 0.28, 0.27, 0.28,
+ 0.22, 0.34, 0.27, 0.25, 0.25, 0.24, 0.35, 0.27, 0.25, 0.29, 0.27,
+ 0.66, 0.37, 0.49, 0.46, 0.42, 0.64, 0.4, 0.48, 0.45, 0.42, 0.81,
+ 0.39, 0.36, 0.37, 0.36, 0.34, 0.34, 0.43, 0.42, 0.34), .Dim = c(5L,
+ 8L), .Dimnames = list(c("a", "b", "c", "d", "e"), c("f", "g",
+ "h", "i", "j", "k", "l", "m")))
print(mat)
f g h i j k l m
a 0.35 0.37 0.34 0.35 0.66 0.64 0.81 0.34
b 0.27 0.28 0.27 0.27 0.37 0.40 0.39 0.34
c 0.26 0.27 0.25 0.25 0.49 0.48 0.36 0.43
d 0.28 0.28 0.25 0.29 0.46 0.45 0.37 0.42
e 0.23 0.22 0.24 0.27 0.42 0.42 0.36 0.34
</code></pre>
<p>For each column I want the lowest <code>k</code> values to be replaced by 0</p>
<p>To achieve this, I used a for loop and ifelse:</p>
<pre><code>k <- 3
for (j in 1:ncol(mat)) { mat[,j][tail(order(mat[,j], decreasing = TRUE, na.last = FALSE), ifelse(nrow(mat)<=k, 0, nrow(mat)-k))] <- 0 }
print(mat)
f g h i j k l m
a 0.35 0.37 0.34 0.35 0.66 0.64 0.81 0.34
b 0.27 0.28 0.27 0.27 0.00 0.00 0.39 0.00
c 0.00 0.00 0.25 0.00 0.49 0.48 0.00 0.43
d 0.28 0.28 0.00 0.29 0.46 0.45 0.37 0.42
e 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00
</code></pre>
<p>So, it all worked fine but unfortunately the loop is very slow for a large number of columns.</p>
<p>How can I speed up things?
<code>apply</code> seems not to be suitable as I want to the whole matrix returned.</p> | 3 |

SQL retrieving filtered value in subquery | <p>in this cust_id is a foreign key and <em>ords</em> returns the number of orders for every customers</p>
<pre><code>SELECT cust_name, (
SELECT COUNT(*)
FROM Orders
WHERE Orders.cust_id = Customers.cust_id
) AS ords
FROM Customers
</code></pre>
<p>The output is correct but i want to filter it to retrieve only the customers with less than a given amount of orders, i don't know how to filter the subquery <em>ords</em>, i tried <code>WHERE ords < 2</code> at the end of the code but it doesn't work and i've tried adding <code>AND COUNT(*)<2</code> after the cust_id comparison but it doesn't work.

Form is empty, so it gives me a validation error even before I submit | <p>Im really new to php, so hear me out.
I made a simple page with a form that validates whether the data you sent was ok to send, but it gives me a validation error I made even before I enter anything. Heres the code:</p>
<pre><code> <html>
<body>
<form action="first.php" method="post">
Username:<input type="text" name="username"><br />
Password:<input type="password" name="password"><br />
<input type="submit" name="submit"><br />
</form>
<?php
$errors = array();
$username = $_POST['username'];
$password = $_POST['password'];
$errors = array();
if(!isset($username) || empty($username)){
$errors = "Empty username<br />";
}
if ($username > 10){
$errors['username'] = "Username out of range<br />";
}
if (!empty($errors)){
echo "Error<br />";
print_r ($errors);
}

Can't get polymer databinding to custom html tag to work while it works on standard tags | <p>I'm using polymer 1.3.1 but can't get the following to work inside a polymer-element named: <code>poly-main</code>. The text of the <code><div></code> should be in red but isn't.</p>
<pre><code><div testcolor="[[colorLocalRed]]">
-->ERROR This must be RED because testcolor="[[colorLocalRed]]"
(expected "myred" and styles.css translates this to color="red")
</div>
</code></pre>
<p>with the following at the start of the script tag:</p>
<pre><code>Polymer({
is: 'poly-main',
properties: {
colorLocalRed: {
type: String,
value: "myred",
notify: true
},
</code></pre>
<p>And the following inside styles.css:'</p>
<pre><code>[testcolor="myred"] {
color: red;
}
</code></pre>
<p>Note: the following works as it should:
<code><div testcolor="myred"> some red text </div></code></p>
<p>Not using the custom tag <code>testcolor</code> but using directly style or color is not an option because this example is only to show the problem of databinding to a non-standard html-tag</p> | 3 |
How to form Elastic Search Request to return records using Group By | <p>My requirement is I need to form a request to get the count of All the Guests whose 'arrivalDt' is greater than the current date group by 'resId'.

Regular Expression in java to get parameters from javascript methods | <p>Long story short, i would like to get the parameters list from JavaScript methods in Java. It works well if i got any parameters, but if the parameter list is empty it's just not working.
For example</p>
<pre><code>function() { return fn.num(tra.getMaster_id(fg)+1)
</code></pre>
<p>My regular expression is:</p>
<pre><code>(?<=\({1}).*?(?=\){1})
</code></pre>
<p>The result i get:</p>
<pre><code>tra.getMaster_id(fg
</code></pre>
<p>The result i want is the empty space between the <code>()</code>.</p>
<p>If i test it with <a href="https://regex101.com/" rel="nofollow">Here</a> everything is fine, but in java it didn't working yet :(</p>
<p>I would appreciate any ideas!</p> | 3 |
git: hook processed files? | <p>Good evening
it's strange that git hooks obviously don't know anything about handled files, e.g.:</p>
<pre><code># Checkout any files which were deleted in the local workspace
git ls-files -d | xargs git checkout --
</code></pre>
<p>This command calls the post-checkout script - but does not pass all handled files.</p>
<p>Is there a solution to call a git hook for each handled file and the action happaned to it? (file was update, created, deleted, …)</p>
<p>Thanks a lot for any help!,
kind regards,
Tom</p> | 3 |
How do I access a directive scope from a parent directive/controller? | <p>I have a template that goes something like this: </p>
<pre><code><parent-directive>
<child-directive binding="varFromParent"></child-directive>
<button ng-click="parentDirective.save()"></button>
</parent-directive>
</code></pre>
<p>When executing a function in the <code>parentDirective</code> controller, is it possible to access and manipulate the scope variables of the <code>childDirective</code> for e.g. if I have them set up as so</p>
<pre><code>angular.module('app').directive('parentDirective', function() {
return {
restrict: 'E',
templateUrl: '...',
controllerAs: 'parentDirective',
controller: function($rootScope, $scope) {
//...
this.save = () => {
//Need to manipulate childDirective so that its
//scope.defaultValue == 'NEW DEFAULT'
}
}
}
});
</code></pre>
<p>and </p>
<pre><code>angular.module('app').directive('childDirective', function() {
return {
restrict: 'E',
templateUrl: '...',
scope: {
binding: '='
},
controllerAs: 'childDirective',
link: function(scope, elm, attrs) {
scope.defaultValue = 'DEFAULT';
}
}
});
</code></pre>
<p>How would I go about doing this? Is there any way to do this without setting up a bidirectional binding? I would like to avoid a mess of attributes on the <code><child-directive></code> element if possible. </p> | 3 |
Qt Removing Window Widgets | <p>I'm using Qt5.5 and I would like a window without any widgets, here is a snippet from my Window constructor:</p>
<pre><code> Qt::WindowFlags flags = (Qt::Window
| Qt::WindowTitleHint
| Qt::CustomizeWindowHint)
& ~Qt::WindowMaximizeButtonHint;
setWindowFlags(flags);
</code></pre>
<p>This produces a window with no close widget and no minimize widget, however the maximize widget is still visible and can be clicked on to maximize the window, also the window can be resized by dragging the window edges.</p>
<p>I am trying to create a tool window that is always on top and doesn't have any widgets and is a fixed size.</p>
<p>In QtCreator I've set the sizePolicy to:</p>
<pre><code> Horizontal Policy: Fixed
Vertical Policy: Fixed
</code></pre>
<p>Yet I am still able to resize the window?</p>
<p>I am aware that this is a very similar question to others posted before, but so far having read those and tried the suggestions nothing has worked.</p>
<p>I'm running on Ubtuntu 14.04.</p> | 3 |

How to correctly unwrap `data` inside `data`? | <p>I’m trying to access nested data (<code>Foo.y</code> inside <code>Bar</code> in the example below), but the straightforward approaches for unwrapping <code>Foo</code> inside <code>Bar</code> that come to mind do not work. But how to unwrap it correctly?</p>
<p>Here my data:</p>
<pre><code>module Foo where
import Prelude
data Foo = Foo { y :: Int }
data Bar = Bar { x :: Int
, foo :: Foo }
</code></pre>
<p>The following (of course) does not compile, error is <code>Could not match type { y :: Int } with type Foo</code> — just like <code>Bar</code>, <code>Foo</code> needs unwrapping first:</p>
<pre><code>fn1 :: Bar -> Int
fn1 (Bar { x, foo }) = x + foo.y
</code></pre>
<p>So I put up my hopes for the following, but alas, compiler says “no” (parentheses around <code>Foo</code> constructor don’t help):</p>
<pre><code>fn2 :: Bar -> Int
fn2 (Bar { x, Foo { y } }) = x + y
fn3 :: Bar -> Int
fn3 (Bar { x, Foo f }) = x + f.y
</code></pre>
<p>The following works, using a helper function to do the unwrapping, but there has got to be a better way:</p>
<pre><code>getY (Foo foo) = foo -- helper function
fn4 :: Bar -> Int
fn4 (Bar { x, foo }) = let foo2 = getY foo in
x + foo2.y
</code></pre>
<p>So, how do I do nested “unwrap”?</p>
<p>[EDIT]</p>
<p>After an hour or two of trying things out, I came up with this, which works:</p>
<pre><code>fn5 :: Bar -> Int
fn5 (Bar { x, foo = (Foo f) }) = x + f.y
</code></pre>
<p>Is this the idiomatic way to do it? Why don’t <code>fn2</code> and <code>fn3</code> work?</p> | 3 |

Join multiple Rows as columns with many where and having clauses | <p>I'm trying to solve (a complex?) Problem, which I can't get to work on my own.</p>
<p>I got the following Tables: (Coordinates are dummys)</p>
<p>Table A:</p>
<pre><code>ID | Name |Attribute 1 | Attribute 2 | Lat | Lon | Car Country
1 | Test 1 | Blue | BMW | 6.4 | 6.2 | German
2 | Hallo | Red |Porsche | 6.4 |6.2 | German
3 | Miau | Silver |Ferrari | 2.5 | 1.4 | Italy
</code></pre>
<p>Table B</p>
<pre><code>ID |ID Car| Slot | Path
1 | 1 | 1 |jsjf.jpg
2 | 2 | 1 | hkfu.jpg
3 | 2 | 2 | eqfwg.png
</code></pre>
<p>User can upload a Car with attributes and a coordinate and with unlimited pictures. Pictures are then saved in the Table B with the path, Slot (first Image, second image, ...) and the car it's belonging to.</p>
<p>So now i want to get every car within my radius and the first 3 images. As a Result for the coordinates 6.4&6.2 I need:</p>
<pre><code>ID | Name | Attribute 1 | Attribute 2 | image1 | image2 |image3
1 | Test 1 | Blue | BMW | jsjf.jpg | Null | Null
2 | Hallo | Red | Porsche | hkfu.jpg | eqfwg.png | Null
</code></pre>
<p>My Query at the moment is:</p>
<pre><code>SELECT
a.id,
a.name,
a.attribute1,
a.attribute2,
MAX(CASE WHEN b.slot= 1 THEN b.path ELSE NULL END) image1,
MAX(CASE WHEN b.slot= 2 THEN b.path ELSE NULL END) image2,
MAX(CASE WHEN b.slot= 3 THEN b.path ELSE NULL END) image3,
(
6371 * acos(
cos(
radians( 6.4 )
) * cos(
radians( lat )
) * cos(
radians( lon ) - radians( 6.2 )
) + sin(
radians( 6.4 )
) * sin(
radians( lat )
)
)
) AS distance
FROM
a
left join bon a.id=b.idcar
WHERE carcountry= 'German'
HAVING
distance <= 50
ORDER BY
distance asc LIMIT 0, 10
</code></pre>
<p>Without the Max() and join everything works....</p> | 3 |
Spatial4j - Create circle using centroid and radius in miles | <p>Using Spatial4j, I want to create a circle using a centroid and radius specified in miles (or kilometers). The Javadoc says "The units of "distance" should be the same as x & y." which I am confused by. </p>
<p>I understood x and y (lat, lon) to be in degrees and I don't know how to express the radius in degrees. I want to express it in miles, so I imagine I need to convert miles to degrees, however I also know the conversion is different based on where the centroid is on the surface of the planet.</p>
<p>Is there a way within Spatial4j to easily handle this conversion so I can express the radius in miles and create an accurate circle?</p>
<p>Thanks!</p> | 3 |
Saving and loading ArrayLists in Android | <p>I am working on an android application that will randomly choose a activity for people to do from an array list. I want this list to be edited by the user of the application by adding or removing activities from the list. I would like the list to be loaded when the application is opened and saved when paused, closed, or destroyed.</p>
<p>I cannot figure out how to store the array list an load it. I have tried to understand posts in the past about this topic but cannot make sense of how to implement them.</p>
<p>I you can help, it would be greatly appreciated.</p> | 3 |
Maintaining a Relative Order of Flex Tasks in a SQL DB | <p>I have a task scheduling app that allows people to create 2 types of tasks...</p>
<p>•Strict- tasks with a set start time and duration
•Flex- tasks that have a duration, but no specific start time</p>
<p>Its also important to understand how flex tasks operate- Flex tasks will continuously reschedule themselves throughout your day in the nearest time you have open...so for example if the only task on your schedule today is a flex task like "Go workout - duration:60mins" and you open the app at 4pm it will have "Go workout" scheduled from 4-5pm for you , if you dont click the checkbox indicating you completed the task and open the app again at 5PM "Go workout will be rescheduled to 5-6pm so that the stuff you are meaning to get done is constantly in your face and trying to fit itself into the gaps of your life. </p>
<p>When a user views their schedule here are the steps I go through:
•Grab a array of all strict tasks
•Grab a array of all flex tasks
•Loop through each strict task and figure out how big of a time gap there is between the task currently being looped's end time and the next tasks start time.
•if a gap exists loop through the flex tasks and see if any of them will fit in the time gap in question. if a flex task is small enough to fit in the time gap add it to the strictTasksArray between the task being currently looped and the next task.</p>
<p>This works great as long as there is no need for any kind of ordering when it comes to flex tasks, but now we have added the ability for users to drag and drop flex tasks into a specific relative order aka if I have Task A,B,C,D
and I drag Task D & B to the front so that its now D,B,A,C it needs to save that ordering so that if you close and reopen the app the app will still remember to try to fit task D in , followed by B, A & C .....but im having big trouble thinking of a efficient way to do considering the ordering is relative and not strict...any ideas how to save relative ordering in a SQLIte DB without having to update every tasks's DB record every time a user drag/drops a task and changes the relative ordering? </p> | 3 |
Correct way to reset class values in unit testing with setup | <p>I'm new to Objective-C so please bear with me. </p>
<p>I have a unit test class that looks something like this:</p>
<pre><code>static NSString * const kTestingUserID = @"userID";
@interface UserPreferencesTest
@property(nonatomic) UserPreferences *userPreferences;
@end
@implementation UserPreferencesTest
- (void)setUp {
[super setUp];
self.userPreferences = [[UserPreferences alloc] init];
}
- (void)testEmptyDictionary {
STAssertFalse([self.userPreferences getLockoutStatus:kTestingUserID],
@"An unset username should always return false");
}
- (void)testBlockManualEntry {
//lock the username
[self.userPreferences lockout:kTestingUserID];
STAssertTrue([self.userPreferences getLockoutStatus:kTestingUserID],
@"The account has been locked out");
}
@end
</code></pre>
<p>They call the following methods in the userPreferences Class:</p>
<pre><code>- (void)lockout:(NSString *) userID {
NSMutableDictionary *dictionary =
[[self.defaults objectForKey:dict] mutableCopy];
dictionary[userID] = [NSNumber numberWithBool:YES];
[self.defaults setObject:[NSDictionary dictionaryWithDictionary:dictionary]
forKey:dict];
[self synchronize];
}
- (BOOL) getLockoutStatus:(NSString *) userID {
NSDictionary *dictionary = [self.defaults objectForKey:dict];
if ([dictionary objectForKey:userID])
return true;
return false;
}
</code></pre>
<p>If I comment out the testBlockManualEntry the test passes. If I run the two tests together the first one, testEmptyDictionary fails. The issue to my understanding is that the username is set in the 2nd test and then is found in the 1st test. </p>
<p>If I were to write a similar unit test in java I would use @Before in my setup and thus setup would run before each test method is called. That would ensure that the userPreferences is created each time and thus the values in that object are reset.</p>
<p>What am I missing here? My understanding of setup in Objective-C is that it should behave similarly (clearly it's not unless theres another bug that I'm not seeing). </p>
<p>Also please ignore the fact that a set would be better used in this scenario than a dict, I'm just looking (and how to fix the issue) for why the tests fail when run together.</p> | 3 |

Dataset Card for [Stackoverflow Post Questions]
Dataset Description
Companies that sell Open-source software tools usually hire an army of Customer representatives to try to answer every question asked about their tool. The first step in this process is the prioritization of the question. The classification scale usually consists of 4 values, P0, P1, P2, and P3, with different meanings across every participant in the industry. On the other hand, every software developer in the world has dealt with Stack Overflow (SO); the amount of shared knowledge there is incomparable to any other website. Questions in SO are usually annotated and curated by thousands of people, providing metadata about the quality of the question. This dataset aims to provide an accurate prioritization for programming questions.
Dataset Summary
The dataset contains the title and body of stackoverflow questions and a label value(0,1,2,3) that was calculated using thresholds defined by SO badges.
