Check with VBA if an element exists on the page | <p>I have 15,000 products and I need to know if they're X, Y or Z. The code below checks on amazon to see if a product is a type of XYZ.</p>
<p>God help me, it actually works. The only exception is when it searches a product no longer sold by Amazon. Then the element ID that I'm looking for which contains the product description that I'm searching doesn't exist on the page, and the code breaks on line </p>
<pre><code>text = document.getelementbyID("result_0").innertext
</code></pre>
<p>with the error "Object variable or With block variable not set".</p>
<p>How do I check if the element exists before proceeding with the rest of the code?</p>
<p>Thanks!</p>

How to extract a list from appsettings.json in .net core | <p>I have an appsettings.json file which looks like this:</p>
<pre><code>{
"someSetting": {
"subSettings": [
"one",
"two",
"three"
]
}
}
</code></pre>
<p>When I build my configuration root, and do something like <code>config["someSetting:subSettings"]</code> it returns null and the actual settings available are something like this:</p>
<p><code>config["someSettings:subSettings:0"]</code></p>
<p>Is there a better way of retrieving the contents of <code>someSettings:subSettings</code> as a list?</p> | 0 |

How to prevent blur on image resize in Chrome? | <p>The images are really blurry if you use resize an image, for example showing a small image with resized dimensions, like;</p>
<pre><code><img src="largeimage.jpg" width=30 height=30 \>
</code></pre>
<p>Its not blurry in other browsers, but in Chrome, its so blurry.
I have looked at in www.twitter.com , their new design has lots of resized images and somehow, they have managed to clear blur in resized images. I have tried these;</p>
<pre><code>image-rendering: crisp-edges;
image-rendering: pixelated;
</code></pre>
<p>But unfortunately, it doesn't solve the problem.</p>
<p>Below is a comparison. On the left, you can see that it is quite blurry, compared to that on the right:

Android: Why is the constructor for SoundPool deprecated? | <p>Does it mean that we cannot use it anymore?
What should we use if the min API is set below 21?

Stop a for loop when user is finished entering input in c | <p>First of all, thank you for the assist!</p>
<p>I'm new to the C language (and programming in general) and I'm trying to write a program wherein the user inputs data points. The data points are then saved in an array where they can then be manipulated. </p>
<p>Where I am stuck: I want the user to be able to input (almost) any number of points, then use a 'keyword' of sorts to signal the end of data entry. In this case, the user would type 'done'. </p>
<p>Here's what I have so far:</p>
<pre><code>#include <stdio.h>
#include <string.h>
int main(void) {
printf("\n Welcome! \n\n Please enter each data point. Enter 'done' when finished.\n\n");
double data[1048];
int i, count;
for (i = 1; ;i++) {
printf("Data[%i]: ", i);
scanf("%lf", &data[i]);
if (data[i] == 'done') {
break;
} else {
count++;
}
}
}
</code></pre>
<p>I've tried 'return 1;' and 'break;'. Each time, the program works well until the 'keyword' is entered, at which point I get:</p>
<pre><code>Data[8]: Data[9]: ... Data[1120]: Data[1Segmentation fault 11
</code></pre>
<p>The only time it works is if I have it break when the user inputs a particular number (like -1 or 0). But that doesn't quite work for the user since they might have to enter those numbers as data points.</p>
<p>Sorry for the long post, but I appreciate the help!</p> | 0 |
When looking at the differences between X-Auth-Token vs Authorization headers, which is preferred? | <p>What is the difference between the two headers below?<br>

<ol>

<li><p><code>Authorization: Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==</code></p></li>

http post - how to send Authorization header? | <p>How do you add headers to your http request in Angular2 RC6?
I got following code:</p>
<pre><code>login(login: String, password: String): Observable<boolean> {
console.log(login);
console.log(password);
this.cookieService.removeAll();
let headers = new Headers();
headers.append("Authorization","Basic YW5ndWxhci13YXJlaG91c2Utc2VydmljZXM6MTIzNDU2");
this.http.post(AUTHENTICATION_ENDPOINT + "?grant_type=password&scope=trust&username=" + login + "&password=" + password, null, {headers: headers}).subscribe(response => {
console.log(response);
});
//some return
}
</code></pre>
<p>The problem is, that angular doesn't add Authorization header. Instead of that, in request I can see following additional headers:</p>
<pre><code>Access-Control-Request-Headers:authorization
Access-Control-Request-Method:POST
</code></pre>
<p>and sdch added in Accept-Encoding:</p>
<pre><code>Accept-Encoding:gzip, deflate, sdch
</code></pre>
<p>Unfornately there is no Authorization header. How should I add it correctly?</p>
<p>Whole request sent by my code looks as follow:</p>
<pre><code>OPTIONS /oauth/token?grant_type=password&scope=trust&username=asdf&password=asdf HTTP/1.1
Host: localhost:8080
Connection: keep-alive
Pragma: no-cache
Cache-Control: no-cache

Python & Google Places API | Want to get all Restaurants at a specific postion | <p>I want to get all restaurants in London by using python 3.5 and the module <code>googleplaces</code> with the Google Places API. I read the <code>googleplaces</code> documentation and searched here, but I don't get it. Here is my code so far:</p>
<pre><code>from googleplaces import GooglePlaces, types, lang
API_KEY = 'XXXCODEXXX'
google_places = GooglePlaces(API_KEY)
query_result = google_places.nearby_search(

print query_result.html_attributions
for place in query_result.places:
place.get_details()
print place.rating

How can I get a (MM-DD-YYYY) format from a UTC string in javascript? | <p>I am working with a Date object in a different timezone than the console.

Angular 2 Inject Dependency outside Constructor | <p>I am currently digging into DI in Angular 2. I'm implementing a REST-Client using a generic subtypes for concrete Datatypes like this:</p>
<pre><code>class RESTClient<T>{
constructor() {
var inj = ReflectiveInjector.resolveAndCreate([HTTP_PROVIDERS]);
this.http = inj.get(Http);
this.conf = RESTConfiguration;
}
}
class BookClient extends RESTClient<Book>{
constructor(){
// since I dont want to inject the HTTP Providers here, I'm using a custom injector in the super class
super();
}
}
class WriterClient extends RESTClient<Writer>{
...
...
}
</code></pre>
<p>So as I understand, there will be one http service shared between all RESTClients injected by the superclasses REST-Service.</p>
<p>Now I want to have a RESTConfiguration class as such:</p>
<pre><code>@Injectable()
export class RESTConfiguration {
get baseURL() {
return this._baseURL;
}
set baseURL(value) {
alert("sets value to"+value);
this._baseURL = value;
}
private _baseURL;
}
</code></pre>
<p>It should be configured in the main app as such: </p>
<pre><code>initializeApp(){
this.restconf.baseURL = "http://localhost:3004/";
}
bootstrap(MyApp, [RESTConfiguration]).then();
</code></pre>
<p>I'm now wondering how to inject one singleton instance of my RESTConfiguration into the RESTService class without passing it to the constructor which I want to remain argument-less in order to reduce code duplication and avoid issues with generics in typescript.</p>
<p>In the above example (first code snippet) I'm trying to inject my configuration using the ReflectiveInjector I created which delivers me a custom instance of my Configuration.</p>
<p>I thought about several solutions: </p>
<ol>
<li><p>Getting access to the Apps "global injector" by making one available using a service or some static class property </p></li>
<li><p>Implementing extra singleton-logic into my configuration</p></li>
<li><p>finding a way to use the angular-native injection method outside of the constructor?</p></li>
</ol>
<p>Are there mistakes in my thinking or am I misusing the DI framework ? </p> | 0 |
Problems with cropping a UIImage in Swift | <p>I'm writing an app that takes an image and crops out everything except for a rectangle in the center of the image. (SWIFT) I can't get the crop function to work though. This is what I have now:</p>
<pre><code>func cropImageToBars(image: UIImage) -> UIImage {
let crop = CGRectMake(0, 200, image.size.width, 50)
let cgImage = CGImageCreateWithImageInRect(image.CGImage, crop)
let result: UIImage = UIImage(CGImage: cgImage!, scale: 0, orientation: image.imageOrientation)
UIImageWriteToSavedPhotosAlbum(result, self, nil, nil)
return result
}
</code></pre>
<p>I've looked at a lot of different guides but none of them seem to work for me. Sometimes the image is rotated 90 degrees, I have no idea why it does that.</p> | 0 |
Python how to delete a specific value from a dictionary key with multiple values? | <p>I have a dictionary with multiple values per key and each value has two elements (possibly more). I would like to iterate over each value-pair for each key and delete those values-pairs that meet some criteria. Here for instance I would like to delete the second value pair for the key A; that is: <code>('Ok!', '0')</code>:</p>
<pre><code>myDict = {'A': [('Yes!', '8'), ('Ok!', '0')], 'B': [('No!', '2')]}
</code></pre>
<p>to:</p>
<pre><code>myDict = {'A': [('Yes!', '8')], 'B': [('No!', '2')]}
</code></pre>
<p>I can iterate over the dictionary by key or value, but can't figure out how I delete a specific value.</p> | 0 |

Vector Drawables flag doesn't work on Support Library 24+ | <p>Today, it seems as though Android Nougat was <a href="https://android.googleblog.com/2016/08/android-70-nougat-more-powerful-os-made.html" rel="noreferrer">released</a>. Thus, I am more excited than ever to optimize my app for the new features like split-screen. I would like to push a version of my app that targets SDK version <code>24</code> so that users aren't notified that my app may not work in split-screen. However, doing so means that I should also update to version <code>24</code> of the Support Library. Like many others, I experienced a problem when updating to version <code>23.2.0</code> of the Support Library. However, I followed <a href="https://stackoverflow.com/a/35740506/5432386">this answer</a> and it fixed my issue. Now the issue is returning as of version <code>24.0.0</code> and up of the Support Library. In all of my tests I am using the gradle flag described in the linked answer:</p>
<pre><code>vectorDrawables.useSupportLibrary = true
</code></pre>
<p>It is also important to note that this is only happening on pre-Lolliop devices (Kitkat and below). Lollipop and up works perfectly. When using the following dependencies, the flag works fine:</p>
<pre><code>compile 'com.android.support:support-v4:23.4.0'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.android.support:cardview-v7:23.4.0'
</code></pre>
<p>But when using these dependencies, I get a crash similar to the one I got before using the flag:</p>
<pre><code>compile 'com.android.support:support-v4:24.2.0'
compile 'com.android.support:appcompat-v7:24.2.0'
compile 'com.android.support:design:24.2.0'
compile 'com.android.support:cardview-v7:24.2.0'

Angular 2 Dynamic Menu | <p>I'm playing around with Angular 2.
Currently I wonder what is the best way to implement a dynamic menu component.
The idea is to have a global menu component that receives menu items for every other content component in the app.</p>
<p>One idea was, to have a menu.component, a menu.service and other components, that use the service. The service is referenced globally in app.module.
The menu.components subscribes to an observable and dynamically add items that get pasted in. I think this is not the best solution.</p>
<p>Another idea is, that I put the menu selector/tag in every components template and paste data to the menu component directly. Currently I stuck in how to get items to the menu.component, so that the ngFor generates the menu items after it was initialized.</p>
<p><strong>So the question is: Are there any "best practices" or common way to do this?</strong></p>
<p>Guess I need some more basics in Angular 2, but it would be nice if you can lead me on the right path. It's just a learning project :)</p>

Using junit test to pass command line argument to Spring Boot application | <p>I have a very basic Spring Boot application, which is expecting an argument from command line, and without it doesn't work. Here is the code.</p>
<pre><code>@SpringBootApplication
public class Application implements CommandLineRunner {
private static final Logger log = LoggerFactory.getLogger(Application.class);
@Autowired
private Reader reader;
@Autowired
private Writer writer;
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
@Override
public void run(String... args) throws Exception {
Assert.notEmpty(args);
List<> cities = reader.get("Berlin");
writer.write(cities);
}
}
</code></pre>
<p>Here is my JUnit test class.</p>
<pre><code>@RunWith(SpringRunner.class)
@SpringBootTest
public class CityApplicationTests {
@Test
public void contextLoads() {
}
}
</code></pre>
<p>Now, <code>Assert.notEmpty()</code> mandates for passing an argument. However, now, I am writing JUnit test for the same. But, I get following exception raise from the <code>Assert</code>.</p>

How to calculate sum of two polynomials? | <p>For instance 3x^4 - 17x^2 - 3x + 5. Each term of the polynomial can be represented as a pair of integers (coefficient,exponent). The polynomial itself is then a list of such pairs like<br>
<code>[(3,4), (-17,2), (-3,1), (5,0)]</code> for the polynomial as shown.</p>
<p>Zero polynomial, 0, is represented as the empty list <code>[]</code>, since it has no terms with nonzero coefficients.</p>
<p>I want to write two functions to add and multiply two input polynomials with the same representation of tuple (coefficient, exponent):</p>
<ol>
<li><code>addpoly(p1, p2)</code></li>
<li><code>multpoly(p1, p2)</code></li>
</ol>
<p>Test Cases:</p>
<ul>
<li><p><code>addpoly([(4,3),(3,0)], [(-4,3),(2,1)])</code> <br>
should give <code>[(2, 1),(3, 0)]</code></p></li>
<li><p><code>addpoly([(2,1)],[(-2,1)])</code> <br>
should give <code>[]</code></p></li>
<li><p><code>multpoly([(1,1),(-1,0)], [(1,2),(1,1),(1,0)])</code> <br>
should give <code>[(1, 3),(-1, 0)]</code></p></li>
</ul>
<p>Here is something that I started with but got completely struck!</p>
<pre><code>def addpoly(p1, p2):
(coeff1, exp1) = p1
(coeff2, exp2) = p2
if exp1 == exp2:
coeff3 = coeff1 + coeff2

IntelliJ IDEA - Address localhost:1099 is already in use | <p>I try to launch a web application with IntelliJ IDEA, but I get an error: <code>localhost:1099 already in use</code>.</p>
<p><img src="https://i.stack.imgur.com/BOR1F.png" alt="port 1099 is already in use"></p>
<p>I checked the port 1099 with <code>lsof -i:1099</code> and many other relative commands, so I'm pretty sure the port 1099 is free.</p>
<p>This is my running configuration:</p>
<p><img src="https://i.stack.imgur.com/nfh7R.png" alt="configs"></p>
<p>I've also changed the <code>JMX port</code> to 6666 & 6667 & 6668... and it doesn't work, so I think it's not really related to the port itself.</p>
<p>I am so confused... did anyone else have this problem? </p>

Setting hidden datalist option values | <p>In the snippet below, I have two methods to choose an item: input with datalist and traditional select with options.</p>
<p>The select element keeps the option values hidden, and we're still able to get it with <code>this.value</code>. However, with the datalist, the value is actually displayed and the text content of the option is displayed as a secondary label.</p>
<p>What I'd like is to have the input+datalist approach behave like a traditional select, where "Foo" and "Bar" are shown as options that when selected have values of "1" and "2" respectively.</p>
<p>I've also added a repeated name "Foo" with value "3". This is to show that any solution must not depend on unique options.</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">

hasNext() for ES6 Generator | <p>How would I implement hasNext() method for a generator. I have tried many options like adding the generator as a return statement and yielding from the closure. Getting the first value printing it and then using the while etc, but none of them actually worked. </p>

Predicted vs. Actual plot | <p>I'm new to R and statistics and haven't been able to figure out how one would go about plotting predicted values vs. Actual values after running a multiple linear regression. I have come across similar questions (just haven't been able to understand the code). I would greatly appreciate it if you explain the code.
This is what I have done so far:</p>
<pre><code># Attach file containing variables and responses
q <- read.csv("C:/Users/A/Documents/Design.csv")
attach(q)
# Run a linear regression
model <- lm(qo~P+P1+P4+I)
# Summary of linear regression results
summary(model)
</code></pre>
<p>The plot of predicted vs. actual is so I can graphically see how well my regression fits on my actual data.</p> | 0 |

What is Interface.super | <p>I have recently used default methods in java.
In its implementation I found </p>
<pre><code>public interface DefaultMethod {

@Override
public String showMyName(String name){

Clear localStorage on tab/browser close but not on refresh | <p>Is there a way to detect tab close event to clear the <code>localStorage</code>. I need <code>localStorage</code> to share data across tabs. <code>window.onbeforeunload</code> event works fine but it has 2 issues for me:</p>
<ol>
<li>It also fires on page refresh which I dont want. </li>
<li>I don't need confirm box on tab close.</li>
</ol>
<p>Like when window is closed the <code>sessionStorage</code> is cleared. At same time I can clear <code>localStorage</code> but don't know what event to bind to. I checked a few questions already available but none seems to address this issue there are workarounds by using flags for click on links and form submits but not a clean way to do it. Kindly suggest any solution for this. </p> | 0 |

Spark on Amazon EMR: "Timeout waiting for connection from pool" | <p>I'm running a Spark job on a small three server Amazon EMR 5 (Spark 2.0) cluster. My job runs for an hour or so, fails with the error below. I can manually restart and it works, processes more data, and eventually fails again.</p>
<p>My Spark code is fairly simple and is not using any Amazon or S3 APIs directly. My Spark code passes S3 text string paths to Spark and Spark uses S3 internally.</p>
<p>My Spark program just does the following in a loop: Load data from S3 -> Process -> Write data to different location on S3. </p>
<p>My first suspicion is that some internal Amazon or Spark code is not properly disposing of connections and the connection pool becomes exhausted.</p>

Where to define the maximum number of connections in Postgres? | <p>I want to limit the number of users per database in a multi tenant environment. But there are three levels of max connections and I should be grateful for any advice.</p>
<p><strong>Level 1 Entire Server</strong></p>
<p>By editing the config for Postgresql I can set the Max connection for the all databases on a server</p>
<pre><code>postgresql.conf = max_connections = 100
</code></pre>
<p><strong>Level 2 Per database</strong></p>
<p>I can select and set the database connection limit per database:</p>
<pre><code>SELECT datconnlimit FROM pg_database
</code></pre>
<p><strong>Level 3 Per role</strong></p>
<p>I can select and set the role connection limit per "user":</p>
<pre><code>SELECT rolconnlimit FROM pg_roles
</code></pre>
<p>My questions are </p>
<ol>
<li><p>If the max_connections in postgresql.conf is 100, will it be max connections of all databases regardless database and role settings? e.g. 100 databases can only have 1 connection each simultaneously?</p></li>
<li><p>Where is the best place to limit max connections. At the database level or at the role level?</p></li>
<li><p>Anything other to be considered?</p></li>
</ol>
<p>TIA for any advice or clue!</p> | 0 |
How to get asset file path in Xamarin? | <p>I have <code>data.xlsx</code> file in <code>Assets</code> folder and need to get its path to apply some library.</p>
<p>Found several solutions here but neither works for me. For example -
<a href="https://stackoverflow.com/questions/21775060/file-not-found-exception-in-xamarin-program">File Not Found Exception In Xamarin program</a></p>
<p>I tried to use <code>file:///android_asset/data.xlsx</code> but here is no file too.</p>
<p>I checked the path with: <code>System.IO.File.Exists(filePath);</code></p>
<p>So how to get path to this file? Maybe I have to place it in different folder?</p>
<p><strong>Update</strong>: possibly I can solve it this way: <a href="https://stackoverflow.com/questions/6186866/java-io-filenotfoundexception-this-file-can-not-be-opened-as-a-file-descriptor/33359656#33359656">java.io.FileNotFoundException: This file can not be opened as a file descriptor; it is probably compressed</a></p>
<p>But I can't find where to place it.</p>
<p><strong>Update</strong>: this question is about Java and this is unclear how to use this solution in Xamarin.Android: <a href="https://stackoverflow.com/questions/8474821/how-to-get-the-android-path-string-to-a-file-on-assets-folder">How to get the android Path string to a file on Assets folder?</a></p> | 0 |

Debugger times out at "Collecting data..." | <p>I am debugging a Python (<code>3.5</code>) program with PyCharm (<code>PyCharm Community Edition 2016.2.2 ; Build #PC-162.1812.1, built on August 16, 2016 ; JRE: 1.8.0_76-release-b216 x86 ; JVM: OpenJDK Server VM by JetBrains s.r.o</code>) on Windows 10.</p>
<p><strong>The problem: when stopped at some breakpoints, the Debugger window is stuck at "Collecting data", which eventually timeout.</strong> (with <em>Unable to display frame variables</em>)</p>
<p>The data to be displayed is neither special, nor particularly large. It is somehow available to PyCharm since a conditional break point on some values of the said data works fine (the program breaks) -- it looks like the process to gather it for display only (as opposed to operational purposes) fails.</p>
<p>When I step into a function around the place I have my breakpoint, its data is displayed correctly. When I go up the stack (to the calling function, the one I stepped down from and where I wanted initially to have the breakpoint) - I am stuck with the "Collecting data" timeout again.</p>
<p>There have been numerous issues raised with the same point since at least 2005. Some were fixed, some not. The fixes were usually updates to the latest version (which I have).</p>
<p><strong>Is there a general direction I can go to in order to fix or work around this family of problems?</strong></p>
<hr>
<p>EDIT: a year later the problem is still there and there is still no reaction from the devs/support after the bug was raised.</p>
<hr>
<p><strong>EDIT April 2018: It looks like the problem is solved in the 2018.1 version</strong>, the following code which was hanging when setting a breakpoint on the <code>print</code> line now works (I can see the variables):</p>
<pre><code>import threading
def worker():
a = 3
print('hello')
threading.Thread(target=worker).start()

How to reference control names dynamically in MS Access | <p>I have the following code in an MS Access Form object. </p>
<pre><code>Private Sub UpdatePMText(sLang As String)
'Used to pass both Mandate and Language Info to called Sub that will execute the queries
Dim iMandate As Integer
'Check if there is text in the box.
If Me.Controls("txtInput_PM_" & sLang & "_DRAFT") = Null Or Me.Controls("txtInput_PM_" & sLang & "_DRAFT") = "" Then
MsgBox ("There is no text in the " & sLang & " DRAFT Field." & vbNewLine & "The operation will not be executed.")
Exit Sub
End If
iMandate = Me.txtMandateID
Call modUpdateText.macro_PMText(iMandate, sLang)
End Sub
</code></pre>
<p>If I refer to the Controls directly and simply type out the names of the forms, for example <code>txtInput_PM_EN_DRAFT</code> then the code works as intended.</p>
<p>The error message I get is that Access can't find the "Field" I'm referring to when I am on the first <code>IF</code> statement line. I have tried changing the <code>.Controls</code> to <code>.Fields</code> but that didn't work either.</p>

Android install apk with Intent.VIEW_ACTION not working with File provider | <p>My app has an auto-update feature that download an APK and when the download is finished that a Intent.VIEW_ACTION to open the app and let the user install the downloaded apk</p>
<pre><code>Uri uri = Uri.parse("file://" + destination);

install.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
install.setDataAndType(uri,

activity.startActivity(install);
</code></pre>
<p>This works great for all the device < 24</p>
<p>Now with Android 24 apparently we are not allowed any more to start intents with file:/// and after some googling it was advised to use A File Provider</p>
<p>new code:</p>
<pre><code>Intent install = new Intent(Intent.ACTION_VIEW);
install.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
install.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
Uri apkUri = FileProvider.getUriForFile(AutoUpdate.this,
BuildConfig.APPLICATION_ID + ".provider", file);
install.setDataAndType(apkUri,
manager.getMimeTypeForDownloadedFile(downloadId));
activity.startActivity(install);
</code></pre>
<p>Now activity.startActivity(install); throws an error</p>

Pushing Viewcontroller through navigation controller , Showing Black screen | <p>I being searching this issue in stack overflow but couldn't get an exact answer to the issue, i being stuck in it for long time.
Mine issue is i'm trying to push a TestViewController through navigation controller. when i click the button the TestViewController is being load with navigation bar and the UIScreen is in black colour.</p>
<p>Code of <strong>TestViewController</strong></p>
<pre><code>import UIKit
class TestViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func viewWillAppear(animated: Bool) {
super.viewWillAppear(true)
navigationItem.title = "Test page"
}
}
</code></pre>
<p>Code of Button </p>
<pre><code>@IBAction func secondButtonClicked(sender: AnyObject) {
buttonPressedNumber = "Two Clicked"
buttonTextColor = UIColor.magentaColor()
let a = TestViewController()
let b:UIViewController = a as UIViewController
navigationController?.pushViewController(b, animated: false)
}

Haskell - for loop | <p>if I want to express something like [just a simple example]:</p>
<pre><code>int a = 0;
for (int x = 0; x < n; x += 1)
a = 1 - a;
</code></pre>
<p>what should I do in Haskell, <em>since it doesn't have variable concept?</em> (maybe wrong, see: <a href="https://stackoverflow.com/questions/993124/does-haskell-have-variables">Does Haskell have variables?</a>)</p> | 0 |
Understanding fetch_assoc() | <p>I am trying to understand how/why fetch_assoc works the way it does.
I have the following piece of code: </p>
<pre><code>$results = $connectToDb->fetch("SELECT * FROM customer");
$resultsArray = $results->fetch_assoc();
print_r($resultsArray); //print_r 1
while($row = $results->fetch_assoc()){
print_r($row); //print_r 2
}
</code></pre>
<p>The query returns 3 rows from a table.
Why does the 1st print_r return only the 1st row of the queried data but the 2nd print_r returns all 3? How does putting fetch_assoc into a while loop tell it to do the action more than once? I read that fetch_assoc returns either an associative array or NULL but I'm struggling to understand how the while loop "tells" fetch_assoc to fetch the next row, if that makes sense?</p>
<p>Thank you.</p> | 0 |
Validating JSON against Swagger API schema | <p>I created an API spec from some JSON files and I am trying to test if the files validate against the API spec. </p>
<p>There are some good tools to validate against JSON Schema, but I did not have chance to find a tool to validate against specs created in the Swagger (tool for creating API schema). The only solution I found is generating a client/server in the Swagger-Editor, it is quite cumbersome.</p>
<p>Is there already an existing tool to validate JSON against Swagger Schema?</p> | 0 |

Firebase hosting using custom domain has SSL cert pointing to firebase.com | <p>I am able to complete the <a href="https://firebase.google.com/docs/hosting/custom-domain" rel="nofollow noreferrer">connect to custom domain</a> step successfully and <code>https://example.com</code> is correctly loading my static file app which is hosted on Firebase.</p>
<p>However, browser is warning about the site's SSL certificate is not matching <code>example.com</code>. I looked at the certificate and it is of <code>firebase.com</code>, not <code>example.com</code>.</p>
<p>This certificate is provided by Firebase for <code>example.com</code> (my custom domain name) and I expect it to be matching it. Is this expected?</p>
<p>I know the other solution is to get my own certificate for <code>example.com</code>. However, it seems that Firebase won't let me deploy my own cert.</p>
<h2>Update</h2>
<p>I retried it some time back and it is fixed. And the whole suite of Firebase db/functions and corresponding sdk/cli are working really well. Great for small dev team.</p> | 0 |
angular 2 - show error message for any exception | <p>I'm trying to do the following in Angular 2 (typescript): For each error (especially errors from the backend server) - present the error to the user (in the UI) - in the main component (mainly since I do't want to write same code in each component).</p>
<p>Is it a simple way to do it? I guess what I need is a way to set an "error" member in the main component? How do I do it if I override ExceptionHandler?</p>
<p>thanx,
Pavel.</p> | 0 |
Datatables + PHP: Server-Side Processing on Multiple Tables | <p><strong>How can I get Datatables <em>Server-Side Processing</em> script to work with a custom query? I need to select columns from multiple tables and have Datatables render them.</strong></p>
<p>Datatables.net's Server-Side Processing (SSP) with PHP is summarized here: <a href="https://datatables.net/examples/server_side/simple.html" rel="noreferrer">https://datatables.net/examples/server_side/simple.html</a></p>
<p>I found this <a href="https://stackoverflow.com/questions/9870154/datatables-server-side-processing-inner-join-or-multiple-tables">SO question</a>, but the original poster never provided his solution. I don't have sufficient reputation to ask him to provide more detail.</p>
<p>Here is my raw SQL without using Datatable's SSP</p>
<pre><code>SELECT tbl_houses.style, tbl_houses.roomCount, tbl_residents.firstName, tbl_residents.lastName
FROM tbl_houses, tbl_residents
WHERE tbl_houses.houseID = tbl_residents.residentID
/*
* # Equivalent query using JOIN suggested by @KumarRakesh
* # Note: JOIN ... ON is a synonym for INNER JOIN ... ON
* # Using JOIN conforms to syntax spec'd by ANSI-92 https://stackoverflow.com/a/894855/946957
*
* SELECT tbl_houses.style, tbl_houses.roomCount, tbl_residents.firstName, tbl_residents.lastName
* FROM tbl_houses
* JOIN tbl_residents ON tbl_houses.houseID = tbl_residents.residentID
*/
</code></pre>
<p>How can I get Datatables to run queries off the above using SSP?</p>
<p>It appears <a href="https://github.com/DataTables/DataTables/blob/master/examples/server_side/scripts/server_processing.php#L22" rel="noreferrer">server_processing.php</a> only accepts 1 table and no custom filtering (i.e., <code>WHERE</code> clauses).</p>
<pre><code>// DB table to use
$table = 'datatables_demo';
// Table's primary key
$primaryKey = 'id';
/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
* If you just want to use the basic configuration for DataTables with PHP
* server-side, there is no need to edit below this line.
*/
require( 'ssp.class.php' );
echo json_encode(
SSP::simple( $_GET, $sql_details, $table, $primaryKey, $columns )
);
</code></pre>
<p>However, <a href="https://github.com/DataTables/DataTables/blob/master/examples/server_side/scripts/ssp.class.php#L199" rel="noreferrer">ssp.class.php</a> <strong>does</strong> support filtering using <code>WHERE</code>. I'm thinking I need to modify <code>ssp.class.php</code> to force in my <code>WHERE</code> clause</p>
<p><strong>UPDATE</strong></p>
<p>Found a solution. Will post when I have free time.</p> | 0 |
Type 'TimeZone' has no member 'local' in Swift3 | <p>I am converting project developed in Swift2.3 to Swift3.0 using Xcode8 Beta4. In which I have method to convert date to string, but it fails to convert it.</p>

let formatter:DateFormatter = DateFormatter();
formatter.dateFormat = dateFormat;
formatter.timeZone = TimeZone.local
let str = formatter.string(from: date);

<p>Also in documentation there is no member named <code>local</code>.</p>
<p>Is there any way to use <code>TimeZone</code> directly ? or we have to use <code>NSTimeZone</code> ?</p> | 0 |
how to properly perform HTTP Post of a JSON object using C# HttpClient? | <p>I have a very simple C# Http Client console app, which needs to do an HTTP POST of a json object to a WebAPI v2.
Currently, My app can do the POST using FormUrlEncodedContent:</p>
<pre><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net.Http;
using System.Net.Http.Headers;
using Newtonsoft.Json;
using System.Net.Http.Formatting;
namespace Client1
{
class Program
{
class Product
{
public string Name { get; set; }
public double Price { get; set; }
public string Category { get; set; }
}
static void Main(string[] args)
{
RunAsync().Wait();
}
static async Task RunAsync()
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://localhost:8888/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
var content = new FormUrlEncodedContent(new[]
{
new KeyValuePair<string, string>("Category", "value-1"),
new KeyValuePair<string, string>("Name", "value-2")
});
var result = client.PostAsync("Incident", content).Result;
var r = result;
}
}
}
}
</code></pre>
<p>However, when I try to use JSON in the POST body, I get error 415 - Unsupported media Type:</p>
<pre><code>class Product
{
public string Name { get; set; }
public double Price { get; set; }
public string Category { get; set; }
}
var gizmo = new Product() { Name = "Gizmo", Price = 100, Category = "Widget" };
var response = await client.PostAsJsonAsync("api/products", gizmo);
</code></pre>
<p>Doing explicit JSON serialization does not change the outcome for me:</p>
<pre><code>string json = JsonConvert.SerializeObject(product);
var response = await client.PostAsJsonAsync("api/products", json);
</code></pre>
<p>What is the proper way to handle this, and to be able to POST JSON?</p> | 0 |

Replace <NA> in a factor column | <p>I want to replace <code><NA></code> values in a factors column with a valid value. But I can not find a way. This example is only for demonstration. The original data comes from a foreign csv file I have to deal with.</p>
<pre><code>df <- data.frame(a=sample(0:10, size=10, replace=TRUE),
b=sample(20:30, size=10, replace=TRUE))
df[df$a==0,'a'] <- NA
df$a <- as.factor(df$a)
</code></pre>
<p>Could look like this</p>
<pre><code> a b
1 1 29
2 2 23
3 3 23
4 3 22
5 4 28
6 <NA> 24
7 2 21
8 4 25
9 <NA> 29
10 3 24
</code></pre>
<p>Now I want to replace the <code><NA></code> values with a number.</p>
<pre><code>df[is.na(df$a), 'a'] <- 88
In `[<-.factor`(`*tmp*`, iseq, value = c(88, 88)) :
invalid factor level, NA generated
</code></pre>
<p>I think I missed a fundamental R concept about factors. Am I?
I can not understand why it doesn't work. I think <code>invalid factor level</code> means that <code>88</code> is not a valid level in that factor, right? So I have to tell the factor column that there is another level?</p> | 0 |

How to resolve attribute error in python | <p>on the begin I'll say that I was looking for the answer but can't find it and sorry for so basic question.I created program with TTS. I created global variable called "list_merge", but most of you said that global variables are BAD. So I decided to put this list in init. PS. ignore whitespaces, they exist only because I copied it here.</p>
<p>the error is:
AttributeError: 'Ver2ProjectWithTTS' object has no attribute 'list_merge'</p>
<pre><code>import json
import pyttsx
from openpyxl import load_workbook
class Ver2ProjectWithTTS(object):
def __init__(self):
self.read_json_file()
self.read_xml_file()
self.say_something()
self.list_merge = []
def read_json_file(self):
with open("json-example.json", 'r') as df:
json_data = json.load(df)
df.close()
for k in json_data['sentences']:
text_json = k['text']
speed_json = int(k['speed'])
volume_json = float(k['volume'])
dict_json = {'text': text_json, 'speed': speed_json, 'volume': volume_json}
self.list_merge.append(dict_json)
def read_xml_file(self):

engine.setProperty('volume', item['volume'])
engine.say(cleared_text)
engine.runAndWait()
if __name__ == '__main__':
a = Ver2ProjectWithTTS()
</code></pre>
<p>I'm getting
AttributeError: 'Ver2ProjectWithTTS' object has no attribute 'list_merge'</p>
<p>Any ideas how to avoid this error? Well i'm not good in objectivity and I just cant move on without fixing this. PS. with global variable before init def it worked properly.
Thanks for help :)</p> | 0 |
Exception in thread “main” java.lang.NoClassDefFoundError: org/apache/spark/Logging | <p>I'm new to Spark. I attempted to run a Spark app (.jar) on CDH 5.8.0-0 on Oracle VirtualBox 5.1.4r110228 which leveraged Spark Steaming to perform sentiment analysis on twitter. I have my twitter account created and all required (4) tokens were generated. I was blocked by the <code>NoClassDefFoundError</code> exception. </p>
<p>I've been googling around for a couple of days. The best advice I found so far was in the URL below but apparently my environment is still missing something.</p>
<p><a href="http://javarevisited.blogspot.com/2011/06/noclassdeffounderror-exception-in.html#ixzz4Ia99dsp0" rel="noreferrer">http://javarevisited.blogspot.com/2011/06/noclassdeffounderror-exception-in.html#ixzz4Ia99dsp0</a> </p>
<p>What does it mean by a library showed up in Compile by was missing at RunTime? How can we fix this?</p>
<p>What is the library of Logging? I came across an article stating this Logging is subject to be deprecated. Besides that, I do see log4j in my environment.</p>

<p>I appended the detail of the exception at the end. Here is the procedure I performed to execute the app and some verification I did after hitting the exception:</p>
<ol>
<li>Unzip twitter-streaming.zip (the Spark app)</li>
<li>cd twitter-streaming</li>
<li>run ./sbt/sbt assembly</li>
<li>Update env.sh with your Twitter account</li>

File upload not working | Php | <p>I'm trying to upload a file in php and unable to do it. The file I'm trying to upload is a csv file, but it should not be a concern.

A javascript 'let' global variable is not a property of 'window' unlike a global 'var' | <p>I used to check if a global <code>var</code> has been defined with:</p>
<pre><code>if (window['myvar']==null) ...
</code></pre>
<p>or</p>
<pre><code>if (window.myvar==null) ...
</code></pre>
<p>It works with <code>var myvar</code></p>
<p>Now that I am trying to switch to let, this does not work anymore.</p>
<pre><code>var myvar='a';
console.log(window.myvar); // gives me a
let mylet='b';
console.log(window.mylet); // gives me undefined
</code></pre>
<p>Question:
With a global <code>let</code>, is there any place I can look if something has been defined like I could with <code>var</code> from the <code>window</code> object?</p>
<p><b>More generally</b>:<br>
Is <code>var myvar='a'</code> equivalent to <code>window.myvar='a'</code>?<br>
I hear people say that at the global level, <code>let</code> and <code>var</code> are/behave the same, but this is not what I am seeing.</p> | 0 |

Updates were rejected because the tip of your current branch is behind its remote counterpart | <p>Our workflow is such. We have a branch called <code>dev</code> which I can reach at <code>origin/dev</code>. When we do changes, we create a branch off dev:</p>
<pre><code>git checkout -b FixForBug origin/dev
</code></pre>
<p>Now I have a branch called <code>FixForBug</code> which is tracking (I think that's the right word) <code>origin/dev</code>. Thus, if I do a <code>git pull</code> it'll bring in new changes from <code>origin/dev</code> which is great. Now, when I'm finished with my fix, I push to a remote branch called the same thing.</p>
<p>First I pull down any changes from <code>origin/dev</code> and do a rebase:</p>
<pre><code>git pull --rebase
</code></pre>
<p>Then I push the changes to a remote branch of the same name:</p>
<pre><code>git push origin FixForBug
</code></pre>
<p>Now, there's a branch on the remote server and I can create a pull request for that change to be approved and merged back in to the dev branch. I don't <em>ever</em> push anything to <code>origin/dev</code> myself. I'm guessing this is as pretty common workflow.</p>
<p>The first time I do a <code>git push</code>, it works fine and creates the remote branch. However, if I push a <em>second</em> time (let's say during code-review, someone points out a problem), I get the following error:</p>
<blockquote>
<p>error: failed to push some refs to
'https://github.mydomain.info/Product/product.git'<br />
hint: Updates were rejected because the tip of your current branch is behind its remote counterpart. Integrate the remote changes (e.g. hint: 'git pull ...') before pushing again.<br />
See the 'Note about fast-forwards' in 'git push --help' for details.</p>
</blockquote>
<p>However, if I do a <code>git status</code> it says I'm ahead of <code>origin/dev</code> by 1 commit (which makes sense) and if I follow the hint and run <code>git pull</code>, it says everything is up to date. I <em>think</em> this is because I'm pushing to a different branch than my upstream branch. I can fix this issue by running:</p>
<p><code>git push -f origin FixForBug</code></p>
<p>In that case, it'll push the changes to the remote branch, saying <em>(forced update)</em> and everything <em>appears</em> to be good on the remote branch.</p>
<p><strong>My Questions:</strong></p>
<p>Why is <code>-f</code> required in this scenario? Usually when you're <em>forcing</em> something, it's because you were doing something wrong or at least against standard practice. Am I ok doing this, or will it mess up something in the remote branch or create a hassle for whoever has to eventually merge my stuff into dev?</p> | 0 |
Serialize Java 8 LocalDate as yyyy-mm-dd with Gson | <p>I am using Java 8 and the latest <code>RELEASE</code> version (via Maven) of <a href="https://github.com/google/gson" rel="noreferrer">Gson</a>.
If I serialize a <a href="https://docs.oracle.com/javase/8/docs/api/java/time/LocalDate.html" rel="noreferrer"><code>LocalDate</code></a> I get something like this</p>
<pre><code>"birthday": {
"year": 1997,
"month": 11,
"day": 25
}
</code></pre>
<p>where I would have preferred <code>"birthday": "1997-11-25"</code>. Does Gson also support the more concise format out-of-the-box, or do I have to implement a custom serializer for <code>LocalDate</code>s? </p>
<p>(I've tried <code>gsonBuilder.setDateFormat(DateFormat.SHORT)</code>, but that does not seem to make a difference.)</p> | 0 |

Redux vs plain React | <p>I have been reading some redux tutorials and to be honest I do not see up until now what added value it brings over plain react.</p>
<p>As far as I know I can build an app and manage its state using only react, so, what makes redux something worth using?</p>
<p>Well, I do recognize redux has a few advantages over react, namely:</p>
<ul>
<li>Keeps track of all the actions carried out;</li>
<li>Makes it easier for debugging due to the previous point;</li>
<li>Prevents state from being passed down/up between components.</li>
</ul>
<p>But maybe due to my lack of experience building large apps I am not convinced that it would make my life easier.</p>
<p>Can you elaborate a little more on the advantages of using redux over plain react?</p> | 0 |
Xdebug unable to connect to client, where do I start debugging the debugger? | <p>I'm setting up xdebug for php within sublime text, and xdebug keeps on logging errors related to being unable to connect:</p>
<pre><code>Log opened at 2016-08-18 21:06:01
I: Connecting to configured address/port: localhost:9988.
E: Could not connect to client. :-(
Log closed at 2016-08-18 21:06:01
</code></pre>
<p>I hoped that debugging directly by going to <code>http://localhost:9988</code> in my browser might help, but it simply displays the google chrome error page: "localhost refused to connect". Perhaps the error exists on the other end, that data can't be pushed to the sublime text client, I don't know. Sublime text xdebug does show the message "Reloading /var/log/xdebug/xdebug.log" when I run tests/etc, so it seems to be aware of the php code being run, just doesn't get any further.</p>
<p>So, I never thought I would have to debug xdebug itself, but: How can I debug the xdebug to code editor connection? If this were nginx, I would start debugging the virtualhost, but since it's xdebug... ...I have no idea where to start debugging the lack of an app to connect to?</p>

SAS: Define type when importing .xlsx with PROC IMPORT | <p><strong>Questions:</strong> How do I define the variable type of variables being imported from a .xlsx file when using PROC IMPORT?</p>
<hr>
<p><strong>My work</strong></p>
<p>I am using SAS v9.4. So far as I'm aware, it is vanilla SAS. I do not have SAS/ACCESS etc.</p>
<p>My data looks like this:</p>
<pre><code>ID1 ID2 MONTH YEAR QTR VAR1 VAR2
ABC_1234 1 1 2010 1 869 3988
ABC_1235 12 2 2010 1 639 3144
ABC_1236 13 3 2010 2 698 3714
ABC_1237 45 4 2010 2 630 3213
</code></pre>
<p>The procedure I am running is:</p>
<pre><code>proc import out=rawdata
datafile = "c:\rawdata.xlsx"
dbms = xlsx replace;
format ID1 $9. ;
format ID2 $3. ;
format MONTH best2. ;
format YEAR best4. ;
format QTR best1. ;
format VAR1 best3. ;
format VAR2 best4. ;
run;
</code></pre>
<p>When I run this step, I get the following log output:</p>
<blockquote>
<p>ERROR: You are trying to use the character format $ with the numeric variable ID2 in data set WORK.RAWDATA.</p>
</blockquote>
<p>What this seems to tell me is that SAS automatically assigns the variable type. I want to be able to control it manually. I cannot find documentation which explains how to do this. INFORMAT, LENGTH, and INPUT statements do not seem to work for PROC IMPORT. </p>
<p>I am using PROC IMPORT because it has yielded the greatest success with .xlsx files overall. Two possible solutions I can think of are 1) convert .xlsx to .csv and use INFILE in a DATA step and 2) bring the data in as numeric and convert it to character in a later step. I dislike the first solution because it requires me to manually manipulate the data, a potential source of error (such as leading zeros being removed). I dislike the second because it may unintentionally introduce errors (again, such as with leading zeros) and introduces extraneous work.</p> | 0 |
How to check if object has property javascript? | <p>I have this function:</p>

//do something...
}

How to split url to get url path in JavaScript | <p>I have constructed a url path that are pointing to different hostname <code>www.mysite.com</code>, so for example:</p>
<pre><code>var myMainSite = 'www.mymainsite.com' + '/somepath';
</code></pre>
<p>so this is equivalent to <code>www.mymainsite.com/path/path/needthispath/somepath</code>.</p>
<p>How I'm doing it now is like the code below and this gives me a bunch of indexes of the url in the <code>console.log</code>.</p>
<pre><code>var splitUrl = myMainSite.split('/');
</code></pre>
<p><code>console.log</code> looks like:</p>
<pre><code>0: http://
1: www.
2: mysite.com
3: path
4: path
5: needthispath
6: somepath
</code></pre>
<p>and I concat them like <code>splitUrl[5]+'/'+splitUrl[6]</code> and it doesn't look pretty at all.</p>
<p>So my question is how to split/remove url location <code>http://www.mymainsite.com/</code> to get the url path <code>needthispath/somepath</code> in js? Is there a quicker and cleaner way of doing this?</p> | 0 |

<p>I searched for possible solutions and most suggest to set the locale to UTF-8, so I thought I would get this fixed if I set the locale in Linux to UTF-8, but I found out that it has already been UTF-8 all the time, and despite newly setting it, I'm still having the same problem.</p>

<p>I am running my application on a Tomcat 7 Server (Java version is 1.8 I believe), my setenv.sh starts with: <code>export JAVA_OPTS="-Dfile.encoding=UTF-8 ...</code></p>
<p>Does anybody have a solution to this problem? I need to be able to use those national symbols in directory/file names...</p>

<p>After adding the extra option Dsun.jnu.encoding=UTF-8 at the start of my setenv.sh for Tomcat and restarting something changed.</p>

<p>The code where it happens looks like this:</p>
<pre><code>// output here
File myOutputFile = new File(filePath);
FileOutputStream out = (new FileOutputStream(myOutputFile));
out.write(bytes);
out.close();
</code></pre>
<p>It seems to fail on (new FileOutputStream(myOutputFile)); when it's trying to initialize the FileOutputStream with the File object, which has the path created from a string which was retrieved from the path in the exception above and an added filename at the end.</p>
<p>So now the directory is created, however writing or creating anything inside it still results in the exception above, although the file inside it doesn't event contain national symbols.</p>
<p>Creating paths and files in them when they have no national symbols works as perfectly as it did before the change in setenv.sh, so it looks like the problem is connected to the national symbols within the path still...</p> | 0 |

Why would apache refuse connection to localhost 127.0.0.1 on OSX? | <p>When trying to access sites on my localhost the connection is refused. Two days ago the set up was working without issues with multiple virtual hosts configured. I'm not aware of any changes that could have affected the set up. I spent all day yesterday trying to troubleshoot the issue but have been going around in circles.</p>

<p>I've tried running a port scan for 127.0.0.1 and http port 80 does <em>not</em> show. This and the connection being refused makes me think this is where the issue is but I don't know why. The OSX firewall is turned off. <a href="https://apple.stackexchange.com/questions/131671/problem-accessing-localhost-on-mac-os-x-mavericks-it-was-working-fine-until-i">I've tried the solution posted here</a> but it did not fix it.</p>

# localhost is used to configure the loopback interface

fe80::1%lo0 localhost
127.0.0.1 site.local
127.0.0.1 othersite.local

</code></pre>
<p>I can ping 127.0.0.1. I previously had homebrew installed to run different PHP versions but I've removed that to try and bring the system back to stock. I really don't know what to try next, any help would be really appreciated.</p> | 0 |
Add android.permission.CAMERA with Cordova | <p>I am using the latest version of Cordova (6.3.1) and I want the following permission to appear in the AndroidManifest.xml :</p>
<pre><code><uses-permission android:name="android.permission.CAMERA" />
</code></pre>
<p>Adding this line by hand does not work because the XML is regenerated each time I run the command <code>cordova run android</code></p>
<p>I have added the <code>cordova-plugin-camera</code> to my project with </p>
<pre><code>cordova plugin add cordova-plugin-camera
</code></pre>
<p>This plugin does NOT add the CAMERA permission in the AndroidManifest.xml</p>
<p>I don't know if this is normal</p>
<p>How can I add this permission to my project ?</p>
<hr>
<p><strong>Edit :</strong>
Usually, Cordova plugins are in charge of adding required permissions into the manifest. The camera plugin does not add this specific permission, I wonder :</p>
<ul>
<li>if the plugin should add this permission (bug ? I have opened an issue on their Jira tracker)</li>
<li>if I can add this permission by hand myself, maybe in the Cordova's config.xml</li>
</ul> | 0 |
Spark - How many Executors and Cores are allocated to my spark job | <p>Spark architecture is entirely revolves around the concept of executors and cores. I would like to see practically how many executors and cores running for my spark application running in a cluster. </p>

<pre><code>val conf = new SparkConf().setAppName("ExecutorTestJob")
val sc = new SparkContext(conf)
conf.get("spark.executor.instances")
conf.get("spark.executor.cores")
</code></pre>
<p>Is there any way to get those values using <code>SparkContext</code> Object or <code>SparkConf</code> object etc..</p> | 0 |
