Just like Twitter does:
<a href="https://i.stack.imgur.com/SQRIR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/SQRIR.png" alt="enter image description here"></a></p>
<p>Or it is possible to remove the icon? When the user swipes down, the "Refresh icon" i want to be invisible.</p> | 2 |
java ternary conditions strange null pointer exception | <p>Can someone explain me why in the first case null pointer was detected, but no on the other ?</p>
<p>Maybe he always looks on the first type, but why he does so only if the condition is false..</p>

public void test1() {
final Integer a = null;
final Integer b = false ? 0 : a;
//===> NULL POINTER EXCEPTION

Running C code using FastCGI & NGINX | <p>I am trying to run C code using FastCGI and NGINX. Right now, after following all the steps in this website: <a href="http://chriswu.me/blog/writing-hello-world-in-fcgi-with-c-plus-plus/" rel="nofollow">http://chriswu.me/blog/writing-hello-world-in-fcgi-with-c-plus-plus/</a> </p>
<p>I am at the step where I am about to spawn-fcgi. However, the system that I must use is a 32 bit system where commands such as sudo apt-get install are not supported. I tried copying over the spawn-fcgi binary from my 64 bit system and tried using that like this: <code>./spawn-fcgi -p 8000 -n hello_world</code> command but it is giving me an error saying it cannot execute the binary file (I'm assuming it is because I am for sure on a 32 bit system when trying to use it). In fact, when I executed <code>file spawn-fcgi</code> it told me that it was a 64-bit LSB executable, and as I am running it on a 32-bit system, that's why the "Cannot execute binary file" error is there.</p>
<p>What I'm wondering is if there is anyway I could run a C script using FASTCGI without calling on <code>spawn-fcgi</code> or <code>cgi-fcgi</code> or if there is anyway I could use somehow get these binaries in 32-bit. I tried searching online for 32-bit downloads of FASTCGI but it seems like fastcgi.com is broken as I am unable to access the website. </p>
<p>Please let me know if I've left out any crucial information and I'll be glad to provide it. Thanks!</p> | 2 |
Removing stopwords using NLTK in python | <p>i am using NLTK to remove stopwords from a list element.
Here is my code snippet</p>
<pre><code>dict1 = {}
for ctr,row in enumerate(cur.fetchall()):
list1 = [row[0],row[1],row[2],row[3],row[4]]
dict1[row[0]] = list1
print ctr+1,"\n",dict1[row[0]][2]
list2 = [w for w in dict1[row[0]][3] if not w in stopwords.words('english')]
print list2
</code></pre>
<p>the problem is, this not only removing the stopwords but also it is removing characters from other words e.g. from the word 'orientation' 'i' and more stopwords will be removed and further it is storing characters instead of words in the list2.
i.e. ['O', 'r', 'e', 'n', 'n', ' ', 'f', ' ', '3', ' ', 'r', 'e', 'r', 'e', ' ', 'p', 'n', '\n', '\n', '\n', 'O', 'r', 'e', 'n', 'n', ' ', 'f', ' ', 'n', ' ', 'r', 'e', 'r', 'e', ' ', 'r', 'p', 'l'.......................

<p><strong>Can someone offer a solution and correct me so I understand it better?</strong></p>
<h2>EDIT1</h2>
<p>from <code>man sort</code></p>
<pre><code> -k, --key=POS1[,POS2]
start a key at POS1 (origin 1), end it at POS2 (default end of line). See POS syntax below
POS is F[.C][OPTS], where F is the field number and C the character position in the field; both are origin 1. If neither -t nor -b is in effect, characters in a field are counted from the begin‐
ning of the preceding whitespace. OPTS is one or more single-letter ordering options, which override global ordering options for that key. If no key is given, use the entire line as the key.

set config params from database in yii 1 | <p>I have created CRUD for global configuration parameters. I want to apply this parameters value as main config params (main.php).
I have found some way like add value of these parameters to any .inc file and perform read/write operation. Can anybody help me how can I achieve this? I am beginner in yii.</p>
<p>I have created table structure : </p>
<pre><code>global_config :
Field | Value
pageSize | 20
admin_email| [email protected]

<p>main.php file as below :</p>
<pre><code>.
.
{
'params' = array(
'pageSize' => 10,
'admin_email' => '[email protected]',
);
}
</code></pre>
<p>.
.</p>
<p>I am using config file as show above, I want to change it dynamically that it should get value from database.</p>
<p>So that I can make changes in config file from front-end side. I don't need to perform open/write action on main.php</p> | 2 |

Google test on bare-metal stm32 MCU | <p>I use Google test on almost all parts of my project except MCU (STM32F1) firmware. Now I want to use it for tests directly on MCU to ensure I didn't make any machine-dependent bugs, which may pass tests on x64, but fail on the MCU. Google test requires libpthread, which is obviously not present on the MCU. I use sophisticated gcc 5.2.1 toolchain, so it's <code>g++</code> should be able to build google test. System calls are also properly defined, so tests output should be successfully compiled and printed to serial console.</p>
<p>Is it possible to disable libpthread in Google test and build it for a bare-metal microcontroller? Does anyone have any experience in using unit-tests this way?</p> | 2 |
Nightwatch.js how to use the expect API to verify the page title | <p>I am trying to use only the <a href="http://nightwatchjs.org/api#expect-api" rel="noreferrer">expect API</a> of <a href="http://nightwatchjs.org/" rel="noreferrer">nightwatch.js</a> to verify an html page title, but I can't get the command right.<br>
My guess would be to either check the inner text of the 'title' element, or maybe its value, but It's not working how I would expect it.</p>
<p>If I run the following mocha test:</p>
<pre><code>describe('Open Google', function () {
var expectedTitle = 'Google';
var uri = 'https://www.google.de';
it('should assert the page title', function (browser) {
browser.url(uri);
browser.expect.element('title').to.be.present.before(2000);
browser.assert.title(expectedTitle);
});
it('should verify title.text', function (browser) {
browser.url(uri);
browser.expect.element('title').to.be.present.before(2000);
browser.expect.element('title').text.to.equal(expectedTitle);
});
it('should verify title.value', function (browser) {
browser.url(uri);
browser.expect.element('title').to.be.present.before(2000);
browser.expect.element('title').value.to.equal(expectedTitle);
});
});
</code></pre>
<p>The assert statement works as expected, but with both ways of using expect, I don't receive the page title.</p>
<p>Output is this:</p>
<pre><code>Open Google
√ should assert the page title (4787ms)
1) should verify title.text
2) should verify title.value
1 passing (12s)
2 failing
1) Open Google should verify title.text:
Expected element <title> text to equal: "Google" - Expected "equal 'Google'" but got: ""
at Context.<anonymous> (C:\temp\nightwatch-test\test\google.js:14:18)
2) Open Google should title.value:
Expected element <title> to have value equal: "Google" - Expected "equal 'Google'" but got: "null"

logstash grok pattern to parse mysql queries | <p>I have mysql slowlogs in logstash and I'm wondering if anyone has had any luck parsing the query section to try and categorize statements. I'm stuck right now trying to split up the query by words in capital letters. I'm thinking that I can at least separate the initial statement. The specific question is this: how can I filter a message like this one so that I can at least deal with each section of the query split by words in capital letters? </p>
<p>So this:</p>
<pre><code>SELECT column_one, column_two, COUNT(DISTINCT IF(column_three > 0, CONCAT('m_', column_three), CONCAT('r_', column_one))) AS tally FROM column_four WHERE ...
</code></pre>
<p>would parse into this:</p>
<pre><code>field1: SELECT column_one, column_two,
field2: COUNT(DISTINCT IF(column_three > 0,
field3: CONCAT('m_', column_three),
field4: AS tally
... etc
</code></pre>
<p>Or something similar that would allow me to further clean the query and make it indexable.</p> | 2 |
GitHub repository folder icon is black and not click-able | <p>I am new to GitHub and finding it incredibly hard to learn. I am following the instructions <a href="http://kbroman.org/github_tutorial/" rel="nofollow noreferrer">here</a> to create new repositories from an existing directory containing the project and typing <code>git init</code> ... etc. </p>
<p>However I created a repository in the wrong place and then deleted it by going into Settings at github.com. Then, when I tried to re-push the files the way I wanted it, one of the subfolders is now black (the one I had just deleted the repository for) and now not clickable - i.e. does not appear to be there. See <code>statistics_project1</code> in screenshot below.</p>
<p>It's very hard to troubleshoot a problem like this. There is no error message or explanatory text when you hover over the black sub-folder.</p>
<p>This post seems similar but I don't know. The solution looks complicated.

Checking if there is any data entered into a range of cells using VBA in Excel | <p>I'm trying to call a Sub (New_Row) when the first empty row (minus the last column) is filled. I'm having trouble with how to reference a range of cells in the If statement toward the end. </p>
<pre><code>Sub Data_Added()
'Check if anything has been entered into the first empty row in "Data"
Dim sht As Worksheet
Dim LastRow As Long
Dim LastColumn As Long
Dim StartCell As Range
Sheets("Data").Select
Set sht = Worksheets("Data")
Set StartCell = Range("A1").End(xlDown).Select
Worksheets("Data").UsedRange
LastRow = StartCell.SpecialCells(xlCellTypeLastCell).Row
LastColumn = StartCell.SpecialCells(xlCellTypeLastCell).Column
Set InputRange = sht.Range(StartCell, sht.Cells(LastRow + 1, LastColumn - 1))
If InputRange Is Not Nothing Then
Call New_Row
End If
End Sub
</code></pre>
<p>I've seen people using the Application.Intersect method, but I'm not sure if an intersect makes sense for just one row of cells. Totally new to VBA, though, so I don't know. Right now I'm getting an "Invalid use of Object" error pointing at the "Nothing" in the If statement.</p> | 2 |
Can a combining character be used alone in Unicode? | <p>Let's take <a href="http://www.fileformat.info/info/unicode/char/0301/index.htm" rel="nofollow noreferrer">COMBINING ACUTE ACCENT</a>, for example. Its <a href="http://www.fileformat.info/info/unicode/char/0301/browsertest.htm" rel="nofollow noreferrer">browser test page</a> does include it alone in the page, but it reacts in a strange way: I can't select it with my mouse, and if I try to interact with it in the DOM inspector, it feels like it's not part of the text at all (there's no <em>before</em> and <em>after</em> this character):</p>

Spatial merge in R returns "non-unique matches detected" even though data has unique value | <p>I am trying to merge a SpatialPolygonsDataFrame with a normal data frame.</p>
<p>The SpatialPolygonDataFrame looks as follows:</p>
<pre><code> check1 LargeSpatialDataFrame
......@data:'data.frame' : 206 obs
$latitude : num
$longitude: num
$name1 : int
</code></pre>
<p>The normal dataframe looks as follows:</p>
<pre><code> Val1 name1
18262 662
55484 532
20859 525
</code></pre>
<p>The DataFrame has 210 unique "name1" value and the SpatialPolygonsDataFrame has 206 unique "name1" value.</p>
<p>When I run the below command I get the following "Error in .local(x, y, ...) : non-unique matches detected"</p>
<pre><code> sp::merge(check1,groupdma,by.x="dma",by.y="dma_number",all=TRUE,duplicateGeoms=FALSE)
</code></pre>
<p>How do I fix this error? My main aim is to create a SpatialPolygonsDataFrame that I can pass to the leaflet function to create a chloropeth map. I have tried the link <a href="http://zevross.com/blog/2015/10/14/manipulating-and-mapping-us-census-data-in-r-using-the-acs-tigris-and-leaflet-packages-3/" rel="nofollow">here</a>, but the area of my polygons always came out to be 0. Hence I am trying to use sp::merge in order to avoid the steps given in the link.</p>
<p>The dataframe and the spatialdataframe, both do not have duplicate id values.</p> | 2 |
How can I strip symbols from my iOS framework? | <p>I have built an iOS framework (release) but when I 'nm'/'otool' it, I see symbols I don't want to be exposed. And that are local symbols (no need to have them exported).</p>
<p>As an example:
I extract the arm64 part using lipo.
And I see what symbols are exported in the binary using "nm -G myLibrary".
I get a lot of:
_kMyLibraryPrivateKey
_MyLibrarySecretThing</p>
<p>I tried to use "strip -x MyLibrary -o MyLibraryStripped", I get no error but the binary is still the same size and I get the same result with the 'nm' command.</p>
<p>Why is not doing anything? how can I remove all these symbols from my framework and only keep the one that are needed by apps using it?</p>
<p>Any help welcome!! Thanks!</p> | 2 |
Why is XPath unclean constructed? Why is text() not needed in predicate? | <p>Assume I have:</p>
<pre><code><A>
<B>C</B>
<D>E</D>
</A>
</code></pre>
<p>Then I can output the B-element (including tags) with:</p>
<pre><code>//B
</code></pre>
<p>Which will return </p>
<pre><code><B>C</B>
</code></pre>
<p><strong>But why is text() not needed in a predicate?</strong> The following 2 lines give the same output:</p>
<pre><code>/A[B = 'C']/D
/A[B/text() = 'C']/D
</code></pre>
<p>If XPATH was cleanly constructed I would expect it would be (or in some kind of other element structure):</p>
<pre><code>/A[B = <B>C></B>]/D
</code></pre>
<p>and:</p>
<pre><code>/A[B/text()='C']/D
</code></pre>
<p><strong>Can someone give me a rationale why text() is needed for output, but it is not needed for predicates?</strong> </p> | 2 |

C Programming - Allow / determine / check "space ( )" input in integer | <p>First, sorry for my bad english, okay go to this question above. I was surfing a lot for reference about this question on many websites, but i didn't find the right answer yet.</p>
<p>I'm trying to make a C program which this program can determine if the user input an integer or not, if user didn't input an integer then the program retry prompt to user for input an integer and so on. Everything is ok when i use scanf() return value on conditional statement, but the problem is, when user input 'whitespace/blankspace/space' (on ascii code as &#32) and press 'enter', my program just stay running to wait for user input some characters or integer. </p>
<p>I just wish that if the input is 'whitespace/blackspace/space', the program will repeat prompt to user to input an integer or the program just stop.</p>
<p>Here is the case code :</p>
<pre><code>#include <stdio.h>
int main() {
int number, isInt;
printf("Input a number : ");
do {
if ((isInt = scanf("%d", &number)) == 0) {
printf("retry : ");
scanf("%*s");
} else if (number < 0) {
printf("retry : ");
}
} while (isInt == 0 || number < 0);
printf("%d\n", number);
return 0;
}
</code></pre>
<p>I am a newbie in C, and curious about this. I know if i use %[^\n] <-- code format for scanf() string and convert it to integer, the program that i mean will run correctly. Is there another way to solve this using %d code format? or using scanf() ?</p>
<p>Please help me to break my curiosity, Regards :D</p> | 2 |

chrome debugger skipping breakpoints, extension development | <p>I'm trying to figure out how to develop extensions in chrome and started out with the obvious: adblock plus.</p>

<p>AWS tools (marketplace, billing manager) seems to be geared toward "provision new service / host by customer" while what I'm looking for is the customer and license management, user association, authentication (including federated authentication integration with multiple customer portals) and perhaps even listing and catalog services - but when a new customer purchase (or change) a license / user / configuration - I expect to get an API call to my already existing solution - in which I'll decide what to do.</p>
<p>Seems like there should be many services like that - but either they are proprietary, or I'm using the wrong keywords to find the information.</p>

Why are iterators in forEach immutable for a struct but mutable for a class? | <p>The iterator is mutable for a class:</p>
<pre><code>var selections: [Selection] = []
class Selection {
var selected: Bool
init(selected: Bool) {
self.selected = selected
}
}
selections.forEach({ $0.selected = false }) // This works
</code></pre>
<p>but not mutable for a struct:</p>
<pre><code>var selections: [Selection] = []
struct Selection {
var selected: Bool
}
selections.forEach({ $0.selected = false }) // This doesn't work because $0 is immutable

R ggplot: stat = "identity" is not working for some reason | <p>I have a datafile which looks something like this...</p>
<pre><code>Rate <- runif(14, 0, 20)
Day <- c("Sunday", "Monday", "Tuesday",
"Wednesday", "Thursday", "Friday", "Saturday",
"Sunday", "Monday", "Tuesday",
"Wednesday", "Thursday", "Friday", "Saturday")
Grouper <- c(rep(1, 7), rep(2, 7))
df <- data.frame(Rate, Day, Grouper)
</code></pre>
<p>...and I want to make a bar chart with two bars for each day: one bar for <code>Grouper = 1</code> and one bar for <code>Grouper = 2</code>. The y-value is not a count, it's the <code>Rate</code> variable, so I need to use <code>stat = "identity"</code> to make it work...</p>
<pre><code># Set max chart height
maxlimit = max(df$Rate) * 1.1
# Actual plot code
ggplot(df, aes(Day, Rate)) +
geom_bar(stat = "identity") +
geom_bar(aes(fill = Grouper), position = "dodge") +
scale_y_continuous(limits = c(0, maxlimit)) +
theme_classic()

<p>...but I am still getting the error <code>stat_count() must not be used with a y aesthetic.</code> Can someone explain to me why I am getting this error and what I can do to fix it?</p> | 2 |
Laravel 5 abort not returning error message | <p>I'm trying to throw an error from my Laravel 5.1 app to my frontend Angular app. The thrown errors are not returning the actual status message, which I need:</p>

JQuery Datatables add new row from text box | <p>I'm creating a page that lists the stats of players in a jQuery Datatable. So far I've been able to display the data that is in the actual database, but I have not been able to add any new players. I created an add button and from for inputing the new player, but I get this error "Datatables warning: table id=test - Requested unknown parameter 'id' for row 3, column 0. For more information about this error please see, <a href="https://datatables.net/manual/tech-notes/4" rel="nofollow">https://datatables.net/manual/tech-notes/4</a> " and a blank row is added to the table after I click ok.

SQL Server messages system with conversation list | <p>Good morning!</p>
<p>I have developed a web application to allow people to exchange messages.</p>
<p>I use SQL Server 2008 and Classic ASP on Windows 2012 Server.</p>
<p>To simplify, suppose there are only 2 tables:</p>
<pre><code>tUsers
Id INT IDENTITY(1,1)
Username VARCHAR(20)
tMessages
Id INT IDENTITY(1,1)
UserIdFrom INT
UserIdTo INT
SentDate DATETIME
Message VARCHAR(300)
Read TINYINT
</code></pre>
<p>My question is simple, but I can't find a solution specific for MS SQL.</p>
<p>I need to write a query that returns the conversation list between me and other users I talked with.</p>
<p>The list must contain <em>UserId</em> and <em>Username</em> (not mine but of the users I talked with) and must be in reverse order by sent date/time order, and must include the message (from or to me) without answer (as Whatsapp for example).</p>
<p>I found many solutions, but for MySQL the conversion to MS SQL is not working. This is the first time I need help on SQL, but I can't find a solution by myself.</p>
<p>Can anyone give me an example of T-SQL query to solve my problem???</p>
<p>Sorry for my English, I used to speak Italian.</p>
<p>This is my second question on StackOverflow. I hope I have respected the rules.</p>
<p>Thanks in advance.</p> | 2 |
Bootstrap-confirmation not respecting options | <p>Just adding the bootstrap-confirmation extension for Bootstrap popover to some buttons on a project. I'm having issues with the options not being respected. I'm trying to get the popups to work as singletons and dismiss when the user clicks outside of them <code>singleton</code> and <code>data-popout</code> options, respectively - both set to true. I'm also not seeing any of my defined callback behavior happening.</p>
<p>I defined the options both in the HTML tags and in a function and neither works. Still getting multiple boxes and they don't dismiss as expected.</p>
<p>My JS is loaded after all other libraries and is in my <code>custom.js</code> file in my footer.</p>
<p>JS is as follows:</p>
<pre><code>$(function() {
$('body').confirmation({
selector: '[data-toggle="confirmation"]',
singleton: true,
popout: true
});
$('.confirmation-callback').confirmation({
onConfirm: function() { alert('confirm') },
onCancel: function() { alert('cancel') }
});
});
</code></pre>
<p>An example of the box implemented on a button in my HTML is the following:</p>
<pre><code><a class="btn btn-danger" data-toggle="confirmation" data-singleton="true" data-popout="true"><em class="fa fa-trash"></em></a>
</code></pre>
<p>Any pointers would be appreciated. I even changed the default options in the <code>bootstrap-confirmation.js</code> file itself to what I want and still no luck.</p> | 2 |

RESTful API with either Tomcat or Node.js? | <p>I am at a decision fork where i have to pick whether to use Tomcat or Node.js in my project and need advice from experts on this.</p>
<p>Some questions that i have here are:</p>
<ol>
<li>Is Tomcat (Java) or Node.js with Typescript better suited to write a RESTful API which gets values form a Database and has to interact with a another java component?</li>
<li>Does Node.js have unit-testing support? </li>
<li>Is it possible to use websockets with Tomcat for another component of the API which pushes Data to the client? </li>
<li>Is the type system of Java better than the system of Typescript (not all dependencies are available in Typescript (or?) and therefore don’t have types?)? </li>
</ol> | 2 |
Python if function across a vector | <p>I'm new to Python and trying to work out how to do the following.</p>
<h2>I have a data array, X, which looks something like:</h2>
<pre><code>X = [ 1 2 3
4 5 6
7 8 9
10 11 12];
</code></pre>
<p>Such that the first column <code>X[0]</code> is,</p>
<pre><code>X[0] =[1
4
7
10];
</code></pre>
<p>the second column <code>X[1]</code> is,</p>
<pre><code>X[1] =[2

11];
</code></pre>
<p>and third column <code>X[2]</code> is,</p>
<pre><code>X[2] =[3
6
9
12];
</code></pre>
<p>What I want to do is generate a single random number, <code>k</code>, and if any of the values in the first column <code>X[0]</code> are greater than <code>k</code> I want to multiply the third column by a function (<code>2*X[0]</code>), and if any of the values are less than <code>k</code> I want to multiply by a different function (<code>2*k</code>).</p>
<p>So if <code>k=2</code>, the third column becomes:
and third column <code>X[2]</code> is,</p>

6*2*X[0,1]
9*2*X[0,2]

Can't access dropdown select using Selenium in Python | <p>I'm new to using Selenium in Python and I'm trying to access index data on Barclays Live's website.

Delete Row in Google Sheet depending on other Google Sheet cell valuie | <p>Is it possible to write a google script that will delete a row in a Google Sheet, based on cell values for a given range, in another google sheet?</p>
<p>I've done some research on how to do this all in the same google sheet, but my limited experience with writing google sheet scripts has prevented me from understanding if what I described is possible, and how. </p>
<p>This is a script I have so far. This will delete rows in a range of my active spreadsheet if a cell in Column F contains the word "id:123456". What I'd like to be able to do, is to modify this code so that if the word "id:123456" is found, it will look in another column of another Google Sheet, and delete rows that contain "id:123456". </p>
<pre><code>function onEdit() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var s = ss.getSheetByName('Sheet1'); // change to your own
var values = s.getDataRange().getValues();
for (var row in values)
if (values[row][6] == 'id:123456')
s.deleteRow(parseInt(row)+1);
};

Angularjs promise inside a for loop | <p>I have the following code that loops through the list of reports, changes each one's name and does an updates. It works fine if there is only one report in the list, but if there are 2 reports, then only the 2nd one gets updated. </p>
<p>When I looked at the network tab, I saw that for the 1st report, there was only a GET call, but for the 2nd report, there were both GET and PATCH calls.</p>
<p>My suspicion is that in this async loop, the variable <code>thisReport</code> gets overwritten when the 2nd report's GET returns and then it goes on to update the 2nd report. The 1st report didn't get a chance to get updated.</p>
<p>My question is how should I rewrite the code so all the reports in the list can get updated. Sorry about the newbie question. All advice are appreciated!</p>
<pre><code>for (var i = 0; i < $scope.listOfReports.length; i++) {
var reportId = $scope.listOfReports[i].Id;
if (reportId > 0) {
var thisReport = reportSvc.query({ key: reportId });
thisReport.$promise.then(function (data) {
thisReport.name = newValue;
thisReport.$update({ key: reportId }).then(function () {
});

How to view the correct client IP in Icecast stats, when Icecast works behind the proxy | <p>I have an Icecast server sitting behind the Apache proxy server, so the connection from the client to Icecast is done by that way:
<br>Client -> Apache server (reverse proxy) -> Icecast server.<br>
The reason I need the proxy, is that I need to have the urls to Icecast via HTTPS on the website, and did not find any other solution except proxying HTTPS to the port, which Icecast sitting on, via HTTP (the proposed solution is here - <a href="https://stackoverflow.com/questions/30237748/why-icecast2-does-not-want-to-give-the-stream-through-https">Why Icecast2 does not want to give the stream through https?</a> , although there they have nginx server as proxy).</p>
<p>Icecast server is showing the stats - the remote ip of the clients connecting to it - and I need that stats. The stats can be viewed via the web-interface of Icecast - base url, following (/admin/listclients.xsl?mount=/mount-point-name). But after proxying the connection, Icecast shows the wrong remote ip there (it always shows the proxy server ip).</p>
<p>Is it possible to make Icecast show the right client ip in those stats (like put there X-Forwarded-For IP instead of REMOTE_ADDR, as the client ip is supposed to be transferred in X-Forwarded-For header to Icecast server by the Apache mod_proxy)?</p>
<p>Here is the config of my Apache proxy virtual host:</p>
<pre><code><VirtualHost *:443>
ServerName my-proxy-server.name
ProxyPreserveHost On
ProxyRequests Off
ProxyPass / http://icecast-server-name:8000/
ProxyPassReverse / http://icecast-server-name:8000/
# Some other strings related to SSL-certificate

Nesting ResourceDictionaries with MergedDictionaries in UWP | <p>I'm trying to split up a <code>ResourceDictionary</code> containing styles for multiple controls in our current UWP application. The file has grown to about 3000 lines and has become a living hell to manage, so I decided to split it up into smaller, more specific <code>ResourceDictionaries</code> and include them using <code>MergedDictionaries</code>.</p>
<p><code>App.xaml</code></p>
<pre><code><common:BootStrapper x:Class="Asteria.Ion.App"

</code></pre>
<p>This will always produce the following exception:
<code>Failed to assign to property 'Windows.UI.Xaml.ResourceDictionary.Source' because the type 'Windows.Foundation.String' cannot be assigned to the type 'Windows.Foundation.Uri'. [Line: 12 Position: 37]</code></p>
<p>I've tried changing the source URI numerous times, but it keeps giving this error. Only commenting out all the <code>ResourceDictionary</code> elements in <code>CustomControls.xaml</code> helps. But then I get exceptions concerning missing styles of course. </p>
<p>Some URI formats I've tried:</p>
<ul>
<li><code>/Styles/Shared.xaml</code></li>
<li><code>Styles/Shared.xaml</code></li>
<li><code>Styles\Shared.xaml</code></li>
<li><code>.\Shared.xaml</code></li>
<li><code>ms-appx:///Styles/Shared.xaml</code></li>
</ul>
<p>None of them work. </p>
<p>Any advice would be appreciated.</p> | 2 |

node - how to read correctly json from a local file? | <p>I am using node.js to serve a page (index.html) where I visualize a network graph, using <a href="http://visjs.org/" rel="nofollow">vis.js</a>. In order to draw a network graph with this library, one needs to provide a <strong>nodes</strong> and <strong>edges</strong> json arrays (<a href="http://visjs.org/examples/network/basicUsage.html" rel="nofollow">see example</a>).</p>
<pre><code>// create an array with nodes
var _nodes_ = [
{id: 1, label: 'Node 1'},
{id: 2, label: 'Node 2'},
{id: 3, label: 'Node 3'},
{id: 4, label: 'Node 4'},
{id: 5, label: 'Node 5'}
];
// create an array with edges
var _edges_ = [
{from: 1, to: 2},
{from: 1, to: 3},
{from: 2, to: 4},
{from: 2, to: 5}
];
</code></pre>
<p>The first version of my <strong>index.html</strong> file looks like:</p>
<pre><code><!doctype html>
<html>
<head>
<title>Network | Basic usage</title>
<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript" src="js/vis.js"></script>
</head>
<body>
<div id="mynetwork"></div>
<script type="text/javascript" >
// create an array with nodes
var _nodes_ = [
{id: 1, label: 'Node 1'},
{id: 2, label: 'Node 2'},
{id: 3, label: 'Node 3'},
{id: 4, label: 'Node 4'},
{id: 5, label: 'Node 5'}
];
// create an array with edges
var _edges_ = [
{from: 1, to: 2},
{from: 1, to: 3},
{from: 2, to: 4},
{from: 2, to: 5}
];
console.log(_nodes_);
console.log(_edges_);
// create a network
var container = document.getElementById('mynetwork');
var data= {
nodes: _nodes_,
edges: _edges_,
};
var options = {
autoResize: true,
clickToUse: false,
width: '800px',
height: '800px'
};
var network = new vis.Network(container, data, options);
</script>
</body>
</html>
</code></pre>
<p>And it is working just fine. However, when I try to read from a local file the <strong>nodes</strong> and <strong>edges</strong> arrays, the network graph doesn't show up:</p>
<pre><code><!doctype html>

// create an array with nodes
var _nodes_;
var _edges_;
$.getJSON('json/nodes.json', function(nodes) {
_nodes_= nodes;
});
$.getJSON('json/edges.json', function(edges) {
_edges_ = edges;
});
console.log(_nodes_);
console.log(_edges_);
// create a network

};
var network = new vis.Network(container, data, options);

</html>
</code></pre>
<p>I am using:</p>
<ul>
<li><p><strong>nodes.json</strong>:</p>
<p>[
{
"id": 1,
"label": "Node 1"
},
{
"id": 2,
"label": "Node 2"
},
{
"id": 3,
"label": "Node 3"
},
{

"to": 2
},
{
"from": 1,
"to": 3
},
{
"from": 1,
"to": 4
}
]</p></li>
</ul>
<p>Is there a difference between creating a json inside your javascript and reading from a file? Can someone help me spot the error here please?</p>

ARM: The easiest way to recreate everything in a resource group into another RG in the same subscription? | <p>I have created a relatively complex IaaS environment in one of my resource groups. The environment is working very well. Now I need to re-build the same environment in another RG for testing and validation.</p>
<p>What would be the easiest way to re-create the same environment in another Resource Group in the same subscription? I tried to export the resource group and downloaded it. The problem is that the file “parameters.json” includes hard coded references to the original resource group name.
Is there an easy way to copy all contents of a RG to another RG in the same environment?
Thank you,</p> | 2 |
ProGuard doesn't obfuscate when building alternative buildType from Android Studio | <p>So in a few words ProGuard doesn't obfuscate sources when I build alternative buildType from Android Studio but works when I use "Generate Signed APK..." option to create apk file.</p>
<p>And some more details here: Android Studio 2.1.1, Gradle version: 2.10, plugin version .2.1.0</p>
<p>I've 3 build types with the following configuration:</p>
<pre><code>buildTypes {
release {
minifyEnabled true
...
proguardFile 'proguard-rules.pro'
proguardFile getDefaultProguardFile('proguard-android.txt')
signingConfig signingConfigs.release
}
releaseDebug {
debuggable true
minifyEnabled true
...
proguardFile 'proguard-rules.pro'
proguardFile getDefaultProguardFile('proguard-android.txt')
signingConfig signingConfigs.release
}
debug {
debuggable true
minifyEnabled false
...
proguardFile getDefaultProguardFile('proguard-android.txt')
testProguardFile 'proguard-rules-test.pro'
signingConfig signingConfigs.release
}
}
</code></pre>
<p>I run application directly from Android Studio and have such results:</p>
<ul>
<li>release - obfuscated</li>
<li>releaseDebug - <strong>NOT</strong> obfuscated</li>
<li>debug - not obfuscated</li>
</ul>
<p>When I use "Generate Signed APK..." option:</p>
<ul>
<li>release - obfuscated</li>
<li>releaseDebug - obfuscated</li>
<li>debug - not obfuscated</li>
</ul>
<p>Is it a build system issue or I missed something?</p>
<p>P.S. Just for clarification, minifyEnabled is already enabled for releaseDebug build type and ProGuard is working but not in this particular case. This is not related to debug mode.</p> | 2 |
Adding line break to long text with resource.resx in ASP.NET MVC | <p>I have tried to separate long text to two lines, when using resource.resx file and logical texts in View.

<p>Tried even to change the visual studio settings, to keep tabs, but havent any effect.</p>
<p>Any new suggestion how to fix this?</p>
<pre><code>Resource.resx: (used shift+enter to add line break)

Spring Boot serving static .webm and .mp4 files with wrong content type | <p>I've got a problem with a Spring Boot application that should serve static .webm and .mp4 files. When I put the files in the <code>static</code> folder on the classpath, the application serves them with content type <code>application/octet-stream</code> instead of <code>video/webm</code>, which makes them not work with <code><video></code> tags. I've tried customizing the resource handler, but it doesn't seem to provide any methods for setting headers. Images and other files work fine.</p>

How to create Angular2 Modal Component WITHOUT Bootstrap and WITHOUT jQuery? | <p>All searches on this topic lead to importing existing components that depend on Bootstrap.</p>
<p>I don't want to use Bootstrap. I want my own simpler HTML markup and way less class names to remember and crowd an already-complicated markup.</p>
<p>I'm fairly comfortable with components, component lifecycle, services, templates, events, observables, and other Angular2 concepts, but I am only able to build an application with nested components whose "parent page" end up in <router-outlet>.</p>
<p>I feel that there may be some lesser-known concepts of Angular2 that most tutorials and even video courses don't address, that would allow me to achieve modal popups. I think I will have to somehow "hack" the DOM to insert some html at the root of the entire webpage so that I can absolutely position the modal. I don't want to use jQuery because it might violate Angular2's inner workings and principles. If possible, I want to know an Angular2-safe way to manipulate the DOM if I have to - I prefer not to chase DOM elements from component code.</p>
<p>I do not only want alert confirmations and prompts. I want to be able to put a form-component on the modal window that would allow the user to save something to the database or choose an item from a list.</p>
<p>I know I'm asking for a lot, but specifically:</p>
<ol>
<li>What html markup and CSS should my popup component have at a minimum? Ideally, I want to put a translucent cover over the entire page, and the actual modal on top of it. to ensure that users can't click outside that modal window.</li>
<li>How, if absolutely required, would services and observables be used to pull this?</li>
<li>Can I just include this modal component's markup (as defined in its @Component({}) decorator) on a host/parent component and open it?</li>
<li>Ideally, on the host component's code, I want to be able to call something like <code>selectRecordModal.onSelected(selectedItem => { .... }).onCancelled( () => { ... });</code></li>
</ol> | 2 |
Using the Roslyn Semantic Model to Find Symbols in a Single .cs File | <p>I am using Roslyn to create an analyzer that warns users if a particular class exposes its fields in an unsynchronized manner, to help prevent race conditions.</p>
<h2>The Problem:</h2>
<p>I currently have working code that checks to make sure a field is private. I’m having trouble with the last piece of the puzzle: figuring out a way to make sure that all fields are only accessed inside a lock block, so they’re (ostensibly) synchronized.</p>
<pre><code>using System;
using System.Collections.Generic;
using System.Collections.Immutable;
using System.Linq;
using System.Threading;
using Microsoft.CodeAnalysis;
using Microsoft.CodeAnalysis.CSharp;
using Microsoft.CodeAnalysis.CSharp.Syntax;
using Microsoft.CodeAnalysis.Diagnostics;
using Microsoft.CodeAnalysis.FindSymbols;
namespace RaceConditions
{
[DiagnosticAnalyzer(LanguageNames.CSharp)]
public class UnsynchronizedMemberAccess : DiagnosticAnalyzer
{
public const string DiagnosticId = "UnsynchronizedMemberAccess";
internal static readonly LocalizableString Title = "UnsynchronizedMemberAccess Title";
private static readonly LocalizableString MessageFormat = "Unsychronized fields are not thread-safe";
private static readonly LocalizableString Description = "Accessing fields without a get/set methods synchronized with each other and the constructor may lead to race conditions";
internal const string Category = "Race Conditions";
private static DiagnosticDescriptor Rule = new DiagnosticDescriptor(DiagnosticId, Title, MessageFormat, Category, DiagnosticSeverity.Warning, isEnabledByDefault: true, description: Description);
public override ImmutableArray<DiagnosticDescriptor> SupportedDiagnostics { get { return ImmutableArray.Create(Rule); } }
//meant to stop other classes and itself from accessing members in an unsychronized fashion.
public override void Initialize(AnalysisContext analysisContext)
{
analysisContext.RegisterSemanticModelAction((context) =>
{
var model = context.SemanticModel;
var root = model.SyntaxTree.GetRoot();
var nodes = model.SyntaxTree.GetRoot().DescendantNodes();
var fields = nodes.OfType<VariableDeclaratorSyntax>()
.Where(v => v.Ancestors().OfType<FieldDeclarationSyntax>().Any());
//since (it appears) that you can't read/write to a an initialized field,
//I think it means you can only read/write inside a block
foreach (BlockSyntax b in nodes.OfType<BlockSyntax>())
{
//where I plan to put code to check references to the fields
}
});
}
}
}
</code></pre>
<p>More specifically, I’d like to be able to ensure everything highlighted by the reference highlighter (at least that’s what Microsoft seems to call it) is inside a lock block, while overloaded parameters do not have to.</p>
<pre><code>using System;
using System.Linq;
using System.Activities;
using System.Activities.Statements;
using System.Data.SqlClient;

<h2>The Research:</h2>
<p>Here, Josh Varty [1] suggests I use <code>SymbolFinder.FindReferencesAsync</code>, which requires a <code>Solution</code> object. Jason Malinowski [2] says that I shouldn’t use do this in an analyzer, since making a <code>MSBuildWorkspace</code> to get a <code>Solution</code> object is too slow, while this person [3] offers an incomplete/missing workaround to the slowness issue (the link to <code>ReferenceResolver</code> seems to be broken).</p>
<p>I have also looked into <code>DataFlowAnalysis</code> (<code>SemanticModel.AnalyzeDataFlow()</code>), but I can’t find any particular methods there that obviously let me guarantee that I’m referencing the field <code>xe</code>, and not the local variable <code>xe</code>.</p>
<h2>The Question:</h2>
<p>I do feel like there is something monumentally obvious I’m missing. Is there some elegant way to implement this that I’ve overlooked? It’d be preferable if the answer uses the semantic model, since I expect I have to use it in other analyzers to figure out where data/references come from, but I realize there are limitations, so any answers without the semantic model are also fine.</p>
<h2>Notes:</h2>
<ul>
<li>Apparently, this issue was also encountered at Github [4], but apparently it’s still being tracked there, and they don’t know if the analyzer should analyze on the project level or not. It still hasn’t been resolved. For the purposes of this analyzer, I will assume that the entire class contained in a single <code>.cs</code> file. Small steps first, eh?</li>
<li>I also searched through John Koerner's website [5] and Josh Varty's website [6], and couldn’t find anything relevant to both analyzers and DataFlowAnalysis.</li>

javascript click not firing after partial view load | <p>I have a view with a javascript section. In this view I have javascript with an onclick event which fires on a tab click to load a partial view this all works perfectly.</p>
<p>Now I know javascript on a partial view wont work properly so in the main view I want to add a click event for when a print button gets clicked.</p>
<pre><code> <script type="text/javascript">
$(function () {
$('#printBtn').click(function () {
debugger;
printElement(document.getElementById("modal-body"));
window.print();
});
$('#tabStrip a').click(function (e) {
e.preventDefault()
var tabID = $(this).attr("href").substr(1);
$(".tab-pane").each(function () {
$(this).empty();
});
$("#" + tabID).empty().append("<div class='loader'><img src='/Content/img/Loader/ajax-loader.gif' alt='Loading' /></div>");
$.ajax({
url: "/Account/CustomerTab",
data: { Id: tabID },
cache: false,
type: "get",
dataType: "html",
success: function (result) {

$(document).trigger('ready');
debugger;
}
});
$(this).tab('show')
});

<p>so the tab click works perfectly but once my partial view is loaded then the print button debugger doesn't get hit. this is the button in my partial view.</p>
<pre><code><button id="printBtn" type="button" class="btn btn-default">Print</button>

Ignore assembly .dll in same folder as executable | <p>I have a .NET application that crashes if I have the MySql.Data.dll assembly in the same folder as the executable but works fine if I move it. A different executable in the same folder is dependent on it so I need to keep it there. </p>
<p>What can I do to make the app ignore this dll?
I assume I can edit the config file but I can't seem to find anyone having had the problem of ignoring a local .dll, so I don't know what to write.</p>
<p>What makes me even more confused is the part about loaded assemblies written in the details of the exception. Mind you the file in the local folder (the one I want to ignore) is versioned 6.9.9.0 and the exception states that it wants to load 6.9.5.0 where as the loaded one (from the GAC) is 6.9.8.0.</p>
<p>This is my configuration file:</p>

ListBox Item layout in XAML/WPF | <p>I am struggling last days to achieve following layout:</p>
<p><a href="https://i.stack.imgur.com/z2k25.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/z2k25.jpg" alt="sketch"></a></p>
<p>I have a ListBox with template for each Item:</p>
<ul>
<li>Label always anchored on left side</li>
<li>Label always anchored on right side</li>
<li>Label (TextBlock) in middle with flexible size</li>
<li>3rd label bellow, so far this is easiest to set :)</li>
</ul>
<p>Main problem in my example is that I can't made middle text (that can be long) to adjust, but not push suffix (red) label while I am resizing ListBox.</p>
<p>I hope that this layout is possible, and that I am missing something trivial. </p>
<p>What's interesting is that 1st example (bellow) work well "outside" listbox. Do I need somehow force realign of listbox while resizing?</p>
<p>Thanks for any help.</p>
<p>I have attached bellow 2 examples I tried (beside many other):</p>

Get value from OpenCV Mat | <p>I have one channel matrix in my program, with next definition: </p>
<pre><code>matchingResult.create(result_cols, result_rows, CV_32FC1);
</code></pre>
<p>It is not a matrix of colours.<br>
I use <em>minMaxLoc</em> method to find of positions of the min and max values:</p>
<pre><code>double minValue;
double maxValue;
cv::Point minLocation;
cv::Point maxLocation;
cv::minMaxLoc(_matchingMap, &minValue, &maxValue, &minLocation, &maxLocation);
</code></pre>
<p>This method returns correct values: </p>
<blockquote>
<p>MinValue: -287909 MaxValue: 682182 MinLocation: [5, 1] MaxLocation:
[4, 2]</p>
</blockquote>
<p>If I print the matrix into <em>cout</em> I'll get same result.</p>
<p>But I can't get same value from the matrix by using the location of max value (maxLocation), or change value of the max.<br>
If I try to get value: </p>
<pre><code>double value = _matchingMap.at<double>(maxLocation);
std::cout<<"Value for "<<maxLocation << " is "<<value << std::endl;
</code></pre>
<p>I'll get something strange:</p>
<blockquote>
<p>Value for [4, 2] is -1.08215e+39</p>
</blockquote>
<p>I want to change values in matrix by using row/coll coordinates, but I do something wrong. I can't find error, may smb can show me the correct way.</p>
<p>How to iterate a matrix I've seen <a href="http://docs.opencv.org/2.4/doc/tutorials/core/how_to_scan_images/how_to_scan_images.html#performance-difference" rel="nofollow">here</a> </p> | 2 |

How to maintain state of checkboxes of Datatable when data loaded via ajax. | <p>I am trying to load Datatable rows with server side calling. I have around 30000 data. By default I have loaded 200 data per page with pagination. Each row contains checkbox. Now the problem is that, suppose I have checked 5 checkboxes among 200 datas, next when going next page and back to previous page again the 5 checkboxes showed me unchecked. How I can now maintain the state of the checkboxes even if I travel through pages. Please help me to give a solution. Thanks. </p> | 2 |

Stemming queries elasticsearch | <p>I've successfully implemented stemming for elasticsearch and thus when I search for "code" I hit upon "codes" and "coding" etc.</p>
<p>My problem arises when I try to make use of the "must_not" field in my queries. When I include "code" in the "must_not" field, it's fine and I still get my results as expected but when I search for "codes" I don't get back any results even though there are documents which have the word "codes" in them for sure.</p>
<p>My query is as follows:</p>
<pre><code>for(i = 0; i < exclude_words.length; i++)
{
must_not.push({term:{text:exclude_words[i].toLowerCase()}});
}
query = {
"filtered": {
"query": {
"dis_max": {
"queries": [
{"match": {"text": term}},
{"match": {"title": term}}
]
}
},
"filter": {
"bool": {
"must_not": must_not
}
}
}
}
</code></pre>
<p>I'm using the elasticsearch api for node.js to construct my queries and get results from elasticsearch.</p>
<p>I'm assuming I'm having this problem because of stemming and that "codes" is stored as "code" in the search index. </p>
<p>Is there a way to solve this without using an external algorithm to stem my queries as well? Or is there an elegant way to solve this issue?</p>
<p>Any help is much appreciated!</p>
<p><strong>Update</strong></p>
<p>This is my analyzer:</p>
<pre><code>{
"settings": {
"analysis": {
"analyzer": {
"stopword_analyzer": {
"type": "snowball",

<p>Essentially, given a setup such as the one outlined, how does one go about making sure that:</p>
<ol>
<li>The row containing the elements is vertically centered depending on the size of the parent container.</li>
<li>The columns making up the row are all centered vertically to each other, despite potentially being different sizes.</li>
<li>The items in each column are aligned horizontally (centered).</li>
<li>The structure of the columns and rows on collapse (with smaller devices) isn't scrambled, and would appear with the columns displayed underneath one another.</li>
</ol>
<p>I have tried several arrangements of nested rows, columns, and divs, but seemingly cannot get the columns to be vertically aligned, despite applying the appropriate classes (in my mind).</p>
<p>Is it possible to do so using a combination of CSS + Bootstrap?</p>
<p>Any advice and help is appreciated!</p> | 2 |
"Repeating" an array of colors multiple times based on another array | <p>I'm building an application wherein the user can select a dataset which will then be shown in a Leaflet map. To distinguish between the markers, each marker will be given a color, based on a variable. The data has a matching legend.</p>
<p>For now, I just use a small dataset for testing and building, but I want my application to be able to work with larger datasets as well.</p>
<p>I set up a basic array with a couple of static colors, which is fine for a small dataset. However when I add a larger dataset, the colors "run out" of course, as you can see below. I increased the amount of colors in the right legend to show what I would like to see happen.</p>

<p>What I would like to have, is way to effectively "repeat" <code>arrayKleur</code> if <code>arrayMetKetens</code> is bigger then the array of colors.</p>
<p><code>arrayMetKetens</code> is an dynamic array, filled with unique values and changes depending on what dataset is selected.</p>
<p><strong>Array for colors:</strong></p>
<pre><code>arrayKleur = ["#b15928", "#6a3d9a", "#ff7f00", "#e31a1c", "#33a02c", "#1f78b4", "#a6cee3", "#b2df8a", "#fb9a99", "#fdbf6f"];
</code></pre>
<p><strong>Generate legend code:</strong></p>
<pre><code>function legenda(){
var HTMLlegenda = '<h4>Legenda</h4>';
// if arrayMetKetens is empty => default legenda text
if (arrayMetKetens.length == 0 ){
HTMLlegenda += '<p>Selecteer een tabel in de "Advanced selection" tab om de legenda weer te geven</p>'
$("#tab1").html(HTMLlegenda);
}
// if arrayMetKetens is filled => generate legenda
else{
$("#tab1").html(arrayMetKetens);
// stuk code om van bovenstaande data een HTML tabel te maken
for(ii = 0; ii < arrayMetKetens.length; ii++){
HTMLlegenda += '<i id="background" style="background:'+arrayKleur[ii]+'">&nbsp;&nbsp;&nbsp;&nbsp;</i>'+arrayMetKetens[ii]+'</br>'
}
$("#tab1").html(HTMLlegenda);
}
}
</code></pre>
<p><strong>getColor function:</strong></p>
<pre><code>function getArray(){
var ketens = [];
for(i=0;i < geojson_dataTable.features.length;i++){
ketens = ketens.concat(geojson_dataTable.features[i].properties[featureVoorSorteer])
}
window.arrayMetKetens = jQuery.unique( ketens );
}
function getColor(keten) {
var i = window.arrayMetKetens.indexOf(keten);
if (i !== -1) {
return arrayKleur[ i ];
}

<p>The problem is when I run server in one terminal and run two clients in another two terminals. If I use Ctrl+C to terminate one client, the server automatically terminates. I'm wondering why the server acts this way. What I'm expecting is the server runs forever. When client 1 terminates, server should still has a live connection with client 2. </p> | 2 |
Flask-Login POST requests turn into GET requests after login | <p>I'm using flask-login to handle authentication for my app, which is an API that expects HTTP Basic Authorization headers as part of each request (so the user can login and make the request without worrying about sessions, cookies, or having to do the login and requesting in separate steps).</p>
<p>My requests are working out like this:</p>
<pre><code>POST /api/group/48
GET /login?next=%2Fapi%2Fgroup%2F48
GET /api/group/48
</code></pre>
<p>That is, a POST request to <code>/api/group/48</code> is getting intercepted and redirected to the /login endpoint (as expected). What happens in /login is not interactive - it takes the Basic Authorization header and logs the user in. </p>
<p>After the login has completed, the client is redirected back to <code>/api/group/48</code> - but this time as a <strong>GET</strong> request, not a <strong>POST</strong>. And in this app, the <code>/api/group/48</code> endpoint is expecting only POST data, so it dies with a 405 (Method not allowed) error.</p>
<p>Is this the expected behavior of flask-login? How can I have it pass through the POST request as originally submitted? (or alternatively, should I be using some different architecture so that the redirect to <code>/login</code>, then back to <code>/api/group/48</code> doesn't take place and the POST data isn't lost?)</p>
<p>I haven't included code, since I don't think this is a code-specific issue. But if it turns out I'm doing something wrong, I can post some sample code.</p>
<p>Thanks to anyone who can help.</p> | 2 |
IAR window layout | <p>Is there a way to save your IAR window layout? Every time I start a debug session it fills my screen 9 different windows.

Reading zipped xml files in Spark | <p>I have a set of large xml files, zipped together in a singe file and many such zip files. I was using Mapreduce earlier to parse the xml using custom inputformat and recordreader setting the splittable=false and reading the zip and xml file.</p>

get parent node/tag of a specific node/tag in c# | <p>I need to delete a specific xml tag using c# but the problem is, that tag may be located in different parent tags.</p>
<p>So I need to search for that specific tag and get its parent tag then delete it.</p>
<p>This is my xml file</p>
<pre><code><PublisherInfo>
<PublisherName value="1">Askquestionzero Publisher</PublisherName>
<PublisherLocation>Ph</PublisherLocation>
<PublisherImprintName>Askquestionzero</PublisherImprintName>
<PublisherLogo>
<Tada>Remove this value and its content</Tada>
</PublisherLogo>
<PublisherURL>Askquestionzero.com</PublisherURL>
</PublisherInfo>
</code></pre>
<p>and this is my code </p>
<pre><code>XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(@"C:\Users\user\Desktop\askquestion.xml");
XmlNode nodeToDelete = xmlDoc.SelectSingleNode("/PublisherInfo/PublisherLogo/Tada");
if (nodeToDelete != null)
{
nodeToDelete.ParentNode.RemoveChild(nodeToDelete);
}
Console.WriteLine(xmlDoc.OuterXml);
</code></pre>
<p>The code works but I need to specify its parent tag. So how loop through the xml file and if the <code>Tada</code> tag is found, get its parent tag then delete it.</p>
<p>expected output:</p>
<pre><code><PublisherInfo>
<PublisherName value="1">Askquestionzero Publisher</PublisherName>
<PublisherLocation>Ph</PublisherLocation>
<PublisherImprintName>Askquestionzero</PublisherImprintName>
<PublisherLogo>
</PublisherLogo>
<PublisherURL>Askquestionzero.com</PublisherURL>
</PublisherInfo>
</code></pre>
<p>Another question:</p>
<p>I need also to change the node of a xml file. The file is the same as above.</p>
<p>Here is the code for changing the xml node/tag name. But it keeps its attribute. What I want it to change its tag name and delete its attribute.</p>
<pre><code>XmlDocument xmlDocument = new XmlDocument();
xmlDocument.Load(@"C:\Users\user\Desktop\askquestion.xml");
Console.WriteLine(xmlDocument.OuterXml);
XmlElement element = (XmlElement)xmlDocument.GetElementsByTagName("PublisherName")[0];
XmlElement renamedElement = (XmlElement)RenameNode(element, null, "new-element");
Console.WriteLine(xmlDocument.OuterXml);
public static XmlNode RenameNode(XmlNode node, string namespaceUri, string qualifiedName)
{
if (node.NodeType == XmlNodeType.Element)
{
XmlElement oldElement = (XmlElement)node;
XmlElement newElement = node.OwnerDocument.CreateElement(qualifiedName, namespaceUri);
while (oldElement.HasAttributes)
{
newElement.SetAttributeNode(oldElement.RemoveAttributeNode(oldElement.Attributes[0]));
}
while (oldElement.HasChildNodes)
{
newElement.AppendChild(oldElement.FirstChild);
}
if (oldElement.ParentNode != null)
{
oldElement.ParentNode.ReplaceChild(newElement, oldElement);
}
return newElement;
}
else
{
return null;
}
}
</code></pre>
<p>The output of the code above:</p>
<pre><code><new-element value="1">Askquestionzero Publisher</new-element>
</code></pre>
<p>Desired output:</p>
<pre><code><new-element>Askquestionzero Publisher</new-element>

R. replacing null value representation with NA | <p>I have tried all the methods that I have found on stackoverflow regarding this topic and nothing worked.</p>
<p>Here is a sample of my dataset called TEST:</p>
<pre><code>x2000 x2001 x2002
100 1200 230
200 2002 280
: 1980 :
</code></pre>
<p>":" represents a missing value. The problem is that I cannot replace this colon with R-accepted NA.</p>
<p>What I have tried:</p>
<pre><code>sum(TEST %in c(":"))
returns: [1] 0
TEST[TEST==":"] <-NA #does nothing
</code></pre>
<p>I tried to save the file as .csv, replace the values with "NA" in excel and it still does nothing. The columns are not factors. if the column contains the value of ":" then the column is "chr" otherwise it is "int". </p> | 2 |
Build EntityManagerFactory using Hibernate and JPA | <p>I'm building a web application using SpringFramework. In the data access layer I was using Hibernate to query data in MySQL, which was working fine. My <code>SessionFactory</code> is build from this method:</p>
<pre><code>public SessionFactory sessionFactory() throws HibernateException {
return new org.hibernate.cfg.Configuration()
.configure()
.buildSessionFactory();
}
</code></pre>
<p>Today I'm going to integrate my data access with JPA, which needs a <code>EntityManagerFactory</code>, IMO I only need to change the code above into the following:</p>
<pre><code>@Bean
public EntityManagerFactory entityManagerFactory() throws HibernateException {
return new org.hibernate.cfg.Configuration()
.configure()
.buildSessionFactory();
}
</code></pre>
<p>simply because <code>SessionFactory</code> extends <code>EntityManagerFactory</code>. However I got an exception</p>
<blockquote>
<p>java.lang.ClassCastException:
org.hibernate.internal.SessionFactoryImpl cannot be cast to
javax.persistence.EntityManagerFactory</p>
</blockquote>
<p>This is quite weird, because <code>SessionFactoryImpl</code> implements <code>SessionFactory</code> while <code>SessionFactory</code> extends <code>EntityManagerFactory</code>. I don't know why the cast fails.</p>
<p>My question is: 1. why the cast is invalid? 2. what's the correct way to build a <code>EntityManagerFactory</code> using Hibernate?</p>
<p><strong>EDIT</strong> Debugger says</p>
<pre><code>factory instanceof SessionFactory //true
factory instanceof EntityManagerFactory //false
</code></pre>
<p>and the source of <code>SessionFactory</code></p>
<pre><code>public interface SessionFactory extends EntityManagerFactory, HibernateEntityManagerFactory, Referenceable, Serializable, Closeable
</code></pre>
<p>I'm sure all the above <code>EntityManagerFactory</code> refers to <code>javax.persistence.EntityManagerFactory</code>.</p> | 2 |
