How to display image from URL in Android | <p>I use this code to display image from url it work but the image is stored in device this is the problem because I want to display this image only if the user is connected to internet</p>
<pre><code>ImageView imageView=(ImageView) findViewById(R.id.imageView3);

Validating a list using Java8 stream | <p>Lets say I have a <code>List<Foo></code> objects and there is a <code>User</code> object inside <code>Foo</code>:</p>
<pre><code>public class Foo {
public User user;
}
public class User {
int id;
int typeId;
}
</code></pre>
<p>Lets say I have a method that takes in a User object and a List objects. Is there an efficient way in Java8 to stream the Foo objects and return fast if any of the Foo objects' User is not the same as the User passed into the method?</p>
<pre><code>public boolean validate(User loggedInUser, List<Foo> objectsToVerify);
</code></pre>
<p>The idea I have is to do:</p>
<pre><code>return objectsToVerify.stream().filter(o -> o.user != loggedInUser).collect(Collections.toList()).isEmpty();

Generic class with generic constructor? | <p>I have a generic class. The constructor needs to accept an argument that is another instance of the same class. The problem is that the other instance can have a different generics type.</p>
<p>Looks like C# allows me to have a method with it's own generics type, but this doesn't appear allowed for the constructor.</p>
<pre><code>public class MyClass<T>
{
public MyClass<T2>(MyClass<T2> parent = null)
{
}
// ... Additional stuff
}
</code></pre>
<p>The code above tells me <code>T2</code> is undefined. It doesn't accept it as a method type.</p>
<p>One approach would be to add a second generic type to my class. But this is awkward and, in many cases, the argument will be <code>null</code> and there is not type.</p>
<p>Does anyone see a simple way around this?</p> | 0 |
Saving a base64 string as an image into a folder on server using C# and Web Api | <p>I am posting a Base64 string via Ajax to my Web Api controller. Code below</p>
<p>Code for converting string to Image</p>
<pre><code>public static Image Base64ToImage(string base64String)
{
// Convert base 64 string to byte[]
byte[] imageBytes = Convert.FromBase64String(base64String);
// Convert byte[] to Image
using (var ms = new MemoryStream(imageBytes, 0, imageBytes.Length))
{
Image image = Image.FromStream(ms, true);
return image;
}
}
</code></pre>
<p>Controller Code</p>
<pre><code>public bool SaveImage(string ImgStr, string ImgName)
{
Image image = SAWHelpers.Base64ToImage(ImgStr);
String path = HttpContext.Current.Server.MapPath("~/ImageStorage"); //Path
//Check if directory exist
if (!System.IO.Directory.Exists(path))
{
System.IO.Directory.CreateDirectory(path); //Create directory if it doesn't exist
}
string imageName = ImgName + ".jpg";
//set the image path
string imgPath = Path.Combine(path, imageName);
image.Save(imgPath, System.Drawing.Imaging.ImageFormat.Jpeg);
return true;
}
</code></pre>
<p>This is always failing with a generic GDI+ error. What am I missing ? Is there a better way to save a specific string as an image on a folder ?</p> | 0 |

How to set laravel 5.3 logout redirect path? | <p>Is there no elegant solution to redirect to a specific page after logging out in Laravel 5.3? </p>
<p>The function being called is from the trait <strong>AuthenticatesUsers</strong>: </p>
<pre><code>public function logout(Request $request)
{
$this->guard()->logout();
$request->session()->flush();
$request->session()->regenerate();
return redirect('/');
}
</code></pre>
<p>This is a default function from the core of laravel. So I have to override the whole function I cannot edit the core.
But isn't there a more simpler solution, cause it feel like overkill to manually logout, flush and regenerate again.</p>
<p>Worked the answers out in an article:
<a href="https://codeneverlied.com/how-to-set-logout-redirect-path-in-laravel-5-8-and-before/" rel="noreferrer">https://codeneverlied.com/how-to-set-logout-redirect-path-in-laravel-5-8-and-before/</a></p> | 0 |
Numpy Array Set Difference | <p>I have two numpy arrays that have overlapping rows:</p>
<pre><code>import numpy as np
a = np.array([[1,2], [1,5], [3,4], [3,5], [4,1], [4,6]])
b = np.array([[1,5], [3,4], [4,6]])
</code></pre>
<p>You can assume that:</p>
<ol>
<li>the rows are sorted</li>
<li>the rows within each array is unique</li>
<li>array <code>b</code> is always subset of array <code>a</code></li>
</ol>
<p>I would like to get an array that contains all rows of <code>a</code> that are not in <code>b</code>.</p>
<p>i.e.,:</p>
<pre><code>[[1 2]
[3 5]
[4 1]]
</code></pre>
<p>Considering that <code>a</code> and <code>b</code> can be very, very large, what is the most efficient method for solving this problem?</p> | 0 |

Logical Or/bitwise OR in pandas Data Frame | <p>I am trying to use a Boolean mask to get a match from 2 different dataframes.
U</p>
<p>Using the logical OR operator:</p>
<pre><code>x = df[(df['A'].isin(df2['B']))
or df['A'].isin(df2['C'])]
Output:
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
</code></pre>
<p>However using the bitwise OR operator, the results are returned successfully. </p>
<pre><code>x = df[(df['A'].isin(df2['B']))
| df['A'].isin(df2['C'])]
Output: x
</code></pre>
<p>Is there a difference in both and would bitwise OR be the best option here? Why doesn't the logical OR work?</p> | 0 |
Using ehcache 3 with Spring Annotations (not using Spring Boot) | <p>I'm trying to get Ehcache 3 working with Spring 4 without using Spring boot.</p>
<p><a href="http://www.ehcache.org/blog/2016/05/18/ehcache3_jsr107_spring.html" rel="noreferrer">Here is a working example out there which uses Spring Boot</a>, but I'm working on an existing application which is not using Spring Boot.</p>
<p>The problem is that spring-context-support (which adds Spring's cache annotations) expects the Ehcache's CacheManager to be on this classpath: net.sf.ehcache.CacheManager</p>
<p>However, in Ehcache 3, the CacheManager class resides on another classpath: org.ehcache.CacheManager.</p>
<p>So, basically spring-context-support does not support Ehcache 3. And you would have to use the JSR-107 annotations directly, not the annotations provided by Spring.</p>
<p>But apparently it works with Spring Boot. Perhaps there is a way to make it work with a standard Spring Application as well. That's what I'm hoping. I really want to be using Spring's own annotations instead of the JSR-107 annotations.</p> | 0 |
Using Numpy's random.choice to randomly remove item from list | <p>According to the <a href="http://docs.scipy.org/doc/numpy-dev/reference/generated/numpy.random.choice.html" rel="nofollow">http://docs.scipy.org/doc/numpy-dev/reference/generated/numpy.random.choice.html</a>, using the <code>replace = False</code> with Numpy's <code>random.choice</code> method should make the sample without replacement. However, this does not seem to work for me:</p>
<pre><code>In [33]: import numpy as np
In [34]: arr = range(5)
In [35]: number = np.random.choice(arr, replace = False)
In [36]: arr
Out[36]: [0, 1, 2, 3, 4]
</code></pre>
<p>The array <code>arr</code> is still <code>range(5)</code> after sampling, and not missing a (random) number as I would expect. How could I sample a number from <code>range(5)</code> without replacement? </p> | 0 |

Change language programmatically (Android N 7.0 - API 24) | <p>I'm using the following code to set specific language in my app. Language is saved into <code>SharedPreferences</code> within the app. <strong>And it works perfectly up to API level 23.</strong> With Android N <code>SharedPreferences</code> works well too, it returns the correct language code-string, but it does not change the locale (sets default language of the phone). What could be wrong?</p>
<p><strong>Update 1:</strong> When I use <code>Log.v("MyLog", config.locale.toString());</code> immediately after <code>res.updateConfiguration(config, dm)</code> it returns correct locale, but language of the app does not changed.</p>
<p><strong>Update 2:</strong> I also mentioned that if I change locale and then restart the activity (using new intent and finish on the old one), it changes the language properly, it even shows correct language after rotation. But when I close the app and open it again, I get default language. It's weird.</p>
<pre><code>public class ActivityMain extends AppCompatActivity {
//...
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Set locale
SharedPreferences pref = PreferenceManager.getDefaultSharedPreferences(this);
String lang = pref.getString(ActivityMain.LANGUAGE_SAVED, "no_language");
if (!lang.equals("no_language")) {
Resources res = context.getResources();
Locale locale = new Locale(lang);
Locale.setDefault(locale);
DisplayMetrics dm = res.getDisplayMetrics();
Configuration config = res.getConfiguration();
if (Build.VERSION.SDK_INT >= 17) {
config.setLocale(locale);
} else {
config.locale = locale;
}
}
res.updateConfiguration(config, dm);
setContentView(R.layout.activity_main);
//...
}
//...
}

Checking file size gt 0 in Powershell | <p>I did search for help regarding my subject but did not find something close to what I need, then here is my doubt:</p>
<p>I need to check the size of a file in a specific folder, if it´s greater than 0 bytes, it´s OK to continue the process, else, abort it writing an output message and sending fail code = 1.</p>
<p>I´ve tried the below but no success on writing the message to the log:</p>
<pre><code>$FileExists1 = "D:\TEST\FILE\test.txt"
IF (Test-Path $FileExists1) {
If ((Get-Item $FileExists1).length -gt 0kb) {
Write-Output [$(Get-Date)]:" FILE IS OK FOR PROCESSING! - RC = $rc"
}
Else {
$rc = 1
Write-Output [$(Get-Date)]:" FILE HAS 0 BYTES AT D:\TEST\FILE\"
Write-Output [$(Get-Date)]:" VALIDATION FINISHED - RC = $rc"
Exit $rc
}

RecyclerView scrolling on insert | <p>I am trying to use <code>RecyclerView</code> to create a chat application. I am using a <code>LinearLayoutManager</code> with <code>setReverseLayout(true)</code>. </p>
<p>When I am scrolled all the way to the bottom (which is the dataset start = newest message) and a new message is inserted into the dataset, the item appears at the bottom of the list as expected (the view is scrolled up to make room for the new item).</p>
<p>The problem I have is when I have scrolled up to see the older messages. When a new message is inserted to the beginning of the dataset, the view is scrolled up by approximately one message height, even though that message isn't even rendered since it's out of the viewport's range.</p>
<p><strong>How can I keep the scrolling behavior, when the view is scrolled to the bottom, but disable it when I have scrolled to the older messages?</strong></p>
<p><strong>UPDATE:</strong>
I also made a small app, where this problem is reproduced:
<a href="https://github.com/ehehhh/RecyclerViewProblem" rel="noreferrer">https://github.com/ehehhh/RecyclerViewProblem</a></p>

Vuex Action vs Mutations | <p>In Vuex, what is the logic of having both "actions" and "mutations?"</p>

Pagination at top and bottom with DataTables | <p>I'm using SB Admin 2 theme, with DataTables jQuery plugin. Is it possible to have pagination positioned at the <strong>top</strong> and at the <strong>bottom</strong> of a table, <strong>at the same time</strong>? If it is, how could I achieve it? This is what I currently have as a working code:</p>
<pre><code><script>
$('#data-table').DataTable({
responsive: true,
"pageLength": 25,
"columnDefs": [ {
"targets" : 'no-sort',
"orderable": false,
}],
"language": {
"lengthMenu": "Show _MENU_ items per page",
"zeroRecords": "Nothing found. Please change your search term",
"info": "Page _PAGE_ of _PAGES_",
"infoEmpty": "No results",
"infoFiltered": "(filtered out of _MAX_)",
"search": "Search:",
"paginate": {
"first": "First",
"last": "Last",
"next": ">>",
"previous": "<<"
}
}
});
</script>
</code></pre>
<p>I have tried using what the official site <a href="https://datatables.net/examples/advanced_init/dom_multiple_elements.html" rel="noreferrer">suggests</a> (removing the code I posted, and then doing a simple copy/paste, and changing the id), but it did absolutely nothing.

Input variable in a router-outlet component | <p>I wanted to know if you guys now a way to have the @Input + ngOnChanges() combination or something doing the same inside a component in .</p>
<p>Basically, I have set a <code>logged: boolean</code> variable in my AppComponent and in my template I have :</p>
<pre><code><router-outlet></router-outlet>
<login [logged]="logged"></login>
</code></pre>
<p>What I want is to be able to <em>watch</em> that <code>logged</code> variable inside a component in the router-outlet so I make stuff here only when logged is as set as true.</p>
<p>I've tried to put <code><router-outlet [logged]="logged"></router-outlet></code> but that doesn't work, and using a variable in a service seems not to fit the ngOnChanges() watch.</p>
<p>Has anyone an idea ? Thanks !</p> | 0 |

How to share a folder between my Mac and a Docker container | <p>Been spending some time trying to setup a Docker container with access to a folder on my Mac.</p>
<p>I know that you can use Docker Volumes to connect to a folder in the host, which on Mac ends up being Linux in VirtualBox, with the -v argument to docker run.</p>
<p>And given that, I figured that I could setup a shared folder in VirtualBox, which could then be mapped to the Docker container.</p>
<p>However, I've not been able to get the Shared Folder I've added to VB to show up.</p>
<p>Here's what I've done:</p>
<p>1) Added a Shared Folder in the VB admin </p>
<p><a href="https://i.stack.imgur.com/LVZtG.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/LVZtG.jpg" alt="VirtualBox Shared Folder config"></a></p>
<p>2) Restarted the VB OS with both docker-machine restart and via the VB app itself</p>
<p>3) Logged into the VB OS via docker-machine ssh</p>
<p>4) Did an ls -l of the root directory </p>
<p>The Users folder (which was there already in VB) shows up, but the folder I added (Projects) does not.</p>
<p>I can't figure out any reason why both folders would not appear. Anyone else having this problem?</p>
<p>Seems like with so many people talking about doing local Development with Docker, and so many devs using Macs, this would be a simple problem. But... alas...not for me so far.</p>
<p>Thanks for any help.</p> | 0 |

Install python modules in mac osx | <p>I am new to python. I am using python 3.5 on mac os x el capitan.
I tried using the command 'pip install requests' in the python interpreter IDLE. But it throws invalid 'syntax error'.</p>
<p>I read about installing modules is only possible in the command line.
So I moved to TERMINAL, but no command is working here also.
(I tried 'python -m pip install requests')</p>
<p>I read that mac os x comes with python 2.7 already installed and I ran 'easy_install pip' but it also works on the 2.7 version.
Then there's discussion about the PATH settings also.</p>
<p>Can please anybody explain to me how I can use my current version in TERMINAL window and what is the PATH scenario.</p>
<p>I am familiar with the environment variable settings and adding pythonpath in windows but not on mac.</p> | 0 |

No 'Access-Control-Allow-Origin' header with ExpressJS to local server | <p>I know that this subject seems to be already answered many time but i really don't understand it.</p>
<ul>
<li>I have an local angular-fullstack app (Express, NodeJs) which has his
<strong>server A</strong> (<em>localhost:9000/</em>).</li>
<li>i have an another local <strong>front app B</strong> (BlurAdmin done with
generator-gulp-angular) (<em>localhost:3000/</em>)</li>
</ul>
<p>My server A was autogenerate with Express and Nodejs:</p>
<pre><code> app.use(function (req, res, next) {
res.setHeader('Access-Control-Allow-Origin', 'http://localhost:3000');
res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');
res.setHeader('Access-Control-Allow-Credentials', false);
next();
});
</code></pre>
<p>In my app B, a GET request to my API of serveur A works </p>
<pre><code>$http.get('http://localhost:9000/api/shows')
</code></pre>
<p>But with a PUT request:</p>
<pre><code>$http.put('http://localhost:9000/api/shows/1', object)
</code></pre>
<p>i have the following error:</p>
<blockquote>
<p>XMLHttpRequest cannot load <a href="http://localhost:9000/api/shows/1" rel="nofollow">http://localhost:9000/api/shows/1</a>. No
'Access-Control-Allow-Origin' header is present on the requested
resource. Origin '<a href="http://localhost:3000" rel="nofollow">http://localhost:3000</a>' is therefore not allowed
access. The response had HTTP status code 403.</p>
</blockquote>
<p>I try with:</p>
<pre><code> $http({
method: "PUT",
url:'http://localhost:9000/api/shows/1',
headers: {
'Content-type': 'application/json'
},
data:object
});
</code></pre>
<p>Not working,</p>
<p>I try with:</p>
<pre><code>res.header('Access-Control-Allow-Origin', '*');
</code></pre>
<p>Not working,</p>
<p>I have installed *ExtensionAllow-Control-Allow-Origin: ** for chrome and that has done nothing (that return just not all the code but only error 403 (forbidden)</p>
<p>I don't really know why this is not working for PUT when it's working with GET.</p>

Node.js doesnot connect with MySQL, PHPMyAdmin | <p>I'm trying to login to a system which uses mysql to store username and password but the login page is in manager.js file as below:</p>

return res.redirect('/');
}
if (req.query.tip == 'error') {
var tip = 'username or password incorrect!';
} else {
var tip = null;
}
res.render('login', { tip: tip });
});
router.post('/login', function (req, res) {
var username = req.body.username;
var password = req.body.password;
var sql = 'SELECT * FROM restaurant_accounts WHERE ra_name=?';
connection.query(sql, [username], function (err, result) {
if (err) throw err;

return res.redirect('/manager/login?tip=error');

var account = result[0];

<p>When I type localhost:80 on my browser and run the express server it displays the following screen:</p>
<p><a href="https://i.stack.imgur.com/vKrWG.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/vKrWG.jpg" alt="enter image description here"></a></p>
<p>Now the username and password are supposed to be stored in mysql database created by somebody else and I use phpmyadmin to add database and have full access to it. But ofcourse since the database is not linked, I can't get past this login page and it shows the "<strong>localhost</strong> refused to connect" error!</p>
<p>Following is my console output <strong>before I try to login to the page</strong>:</p>
<pre><code>C:\Mrestro\RESTaurant_backend-master\rest-server>node bin\www

React-native: How to control what keyboard pushes up | <p>The structure of the app is fairly simple: A searchbar, a listview and react-native-tabs at the bottom. The problem: If I click on the searchbar on Android it pushes the whole app up, so I see the tabs directly over the keyboard. But on iOS the keyboard overlays the whole app, without pushing anything up. Is there any way to control that?<br />
I'm happy to share code / screenshots if the question isn't clear.<br />
Thanks</p>
<p>edit:</p>

Awk replace string in line | <p>NOTE:

I accepted the answer, and I'm posting here the same problem but with slightly different "solution conditions".</p>
<hr>
<p>I have a file <code>test.txt</code> like this (but containing many more lines)</p>
<pre><code>/foo/bar/how /SOME_TEXT_HERE/hello
/foo/bar/are hello/SOME_OTHER_TEXT
/foo/bar/you hello
</code></pre>
<p>I want to get this output:</p>
<pre><code>/foo/bar/how /SOME_TEXT_HERE/how
/foo/bar/are are/SOME_OTHER_TEXT
/foo/bar/you you
</code></pre>
<p>I have tried this:</p>
<pre><code>while read line
do
bla=$(echo $line | cut -f4 -d"/" | cut -f1 -d" ")
sed -i "s/hello/$bla/" test.txt
done <test.txt
</code></pre>
<p>But the output is:</p>
<pre><code>/foo/bar/how /SOME_TEXT_HERE/how
/foo/bar/are how/SOME_OTHER_TEXT
/foo/bar/you how
</code></pre>
<p><strong>NOTE</strong>:</p>
<p>I would like the solution to:</p>
<ol>
<li><p>allow me to define a variable (here, <code>bla</code>) that I will define manually and differently from one file to the other (so not using sthg like basic field position), but using <code>cut</code> or other command as in my example)</p></li>
<li><p>replace a specific string somewhere else in the line by this variable (so not a field position like <code>$2</code>, but really something like <code>s/hello/$bla</code>)</p></li>
</ol>
<p>I'm not sure of this is possible though (obviously I don't know how to do this by myself...), but thanks for your time trying! :)</p> | 0 |
Qt installer stuck | <p>I'm running the <em>Qt Open Source</em> installer on Windows 7.</p>
<p>It's at 46% during the "Retrieving meta information from remote repository" step. It quickly got there and got stuck there 55 minutes already.</p>
<p>I tried restarting the installer and this time it got stuck again at the same step, but at 64%.</p>
<p>Any ideas?</p>
<p><em>Notes:</em></p>
<ul>
<li>The installer name is <code>qt-unified-windows-x86-2.0.3-1-online.exe</code></li>
<li>I believe the Qt version it's going to install is <em>Qt 5.7</em>, as that's the latest Qt version as of now</li>
<li>I'm going to try the offline installer now</li>

User input if statements in Java not working | <p>I am using scanner to take user input.</p>
<pre><code>Scanner scanner = new Scanner(System.in);
Int choice = scanner.nextInt();
if(choice==1) {
System.out.println(" you chosed number 1!")
}
if(choice==2) {
System.out.println(" you chosed number 2!")
}
if(choice==3) {
System.out.println(" you chosed number 3!")
}
if(choice==q) {
System.out.println("the game will end now!");
}
</code></pre>
<p>So when you enter the game you have a menu that pops up. You can chose between 1, 2, 3 or q. If you press any of the numbers the game will take you to those sections.
But if you press q the game will end.</p>
<p>I don't know how to fix so that I can enter q and game ends.</p> | 0 |
Passing Values from one Form to another Form in a Button click | <p>These are my 2 Forms.

string a="preset value";
public Form1()

a = p;
MessageBox.Show("a=p done! and P is: " + p + "---and a is: " + a);
textBox1.Text = "Test 1";
textBox2.Text = a;
textBox3.Text = p;
}
private void button2_Click(object sender, EventArgs e)
{
MessageBox.Show(a);

g = textBox1.Text;
Form1 j = new Form1();
j.set(g);
}
}
}
</code></pre>
<p>See the picture.You can understand the design.</p>
<p>This is what I want to do. 1st I open Form2 using button in Form1. Then I enter a text and click the button("Display in Form1 Textbox"). When it's clicked that value should be seen in the 3 Textboxes in Form1.I used Message Boxes to see if the values are passing or not. Values get passed from Form2 to Form1. But those values are not displays in those 3 Textboxes but the passed values are displayed in Message Boxes. Reason for the 3 Text Boxes can be understood by looking at the code. So what's the error?</p> | 0 |

How to call super of enclosing class in a mixin in Python? | <p>I have the following code, in Django:</p>
<pre><code>class Parent(models.Model):
def save(self):
# Do Stuff A
class Mixin(object):
def save(self):
# Do Stuff B
class A(Parent, Mixin):
def save(self):
super(A, self).save()
# Do stuff C
</code></pre>
<p>Now, I want to use the mixin without blatting the behaviour of the save in Parent. So I when I save, I want to do stuff C, B, and A. I've read <a href="https://stackoverflow.com/questions/27664632/calling-the-setter-of-a-super-class-in-a-mixin">Calling the setter of a super class in a mixin</a> however I don't get it and having read the super docs it doesn't seem to answer my question.</p>

Unable to use an existing Hive permanent UDF from Spark SQL | <p>I have previously registered a UDF with hive. It is permanent not <code>TEMPORARY</code>. It works in beeline.</p>
<pre><code>CREATE FUNCTION normaliseURL AS 'com.example.hive.udfs.NormaliseURL' USING JAR 'hdfs://udfs/hive-udfs.jar';
</code></pre>
<p>I have spark configured to use the hive metastore. The config is working as I can query hive tables. I can see the UDF;</p>
<pre><code>In [9]: spark.sql('describe function normaliseURL').show(truncate=False)
+-------------------------------------------+
|function_desc |
+-------------------------------------------+
|Function: default.normaliseURL |
|Class: com.example.hive.udfs.NormaliseURL |
|Usage: N/A. |
+-------------------------------------------+
</code></pre>
<p>However I cannot use the UDF in a sql statement;</p>
<pre><code>spark.sql('SELECT normaliseURL("value")')
AnalysisException: "Undefined function: 'default.normaliseURL'. This function is neither a registered temporary function nor a permanent function registered in the database 'default'.; line 1 pos 7"
</code></pre>
<p>If I attempt to register the UDF with spark (bypassing the metastore) it fails to register it, suggesting that it does already exist.</p>
<pre><code>In [12]: spark.sql("create function normaliseURL as 'com.example.hive.udfs.NormaliseURL'")
AnalysisException: "Function 'default.normaliseURL' already exists in database 'default';"
</code></pre>
<p>I'm using Spark 2.0, hive metastore 1.1.0. The UDF is scala, my spark driver code is python.</p>
<p>I'm stumped.</p>
<ul>
<li>Am I correct in my assumption that Spark can utilise metastore-defined permanent UDFs?</li>
<li>Am I creating the function correctly in hive?</li>

Min positive value for float? | <p>I'm new to C++!</p>

<p>But if a float can have max 7 digit (<code>≈ 7.225</code>), the min is it not just <code>0,0000001</code>? I'm confused :)</p> | 0 |

How to force application version on AWS Elastic Beanstalk | <p>I'm trying to deploy a new version of my Python/Django application using <code>eb deploy</code>.</p>
<p>It unfortunately fails due to unexpected version of the application. The problem is that somehow <code>eb deploy</code> screwed up the version and I don't know how to override it. The application I upload is working fine, only the version number is not correct, hence, Elastic Beanstalk marks it as <em>Degraded</em>. </p>
<p>When executing eb deploy, I get this error:</p>
<blockquote>
<p>"Incorrect application version "app-cca6-160820_155843" (deployment
161). Expected version "app-598b-160820_152351" (deployment 159). "</p>
</blockquote>
<p>The same says in the health status at AWS Console.</p>
<p>So, my question is the following: How can I force Elastic Beanstalk to make the uploaded application version the current one so it doesn't complain?</p> | 0 |
Laravel issue with loginUsingId (Manual Authentication) | <p>I am trying to implement a <strong>single signon on multiple domains</strong>. The concept is pretty simple i.e to send unique user tokens and then verify these tokens to find the user and then log him in.</p>
<p>Now after verifying the token and then grabbing the user, i do something like this</p>
<pre><code>$loggedInUser = Auth::loginUsingId($user->id, true);
</code></pre>
<p>Now i have a custom middleware where it first checks for a logged in user, i.e</p>
<pre><code>Auth::Check()
</code></pre>
<p>The above works fine for the first time. But on refresh Auth::check() is not validated. I have also tried using all different session drivers but still doesn't work.</p>
<p>I used a similar code on laravel 5.2, and it did work. But on laravel 5.3 its not validating on persistent requests. </p>
<p><strong>Edit: Let me show you my Code</strong>
I have not modified AuthServiceProvider or any other guard. I do have the user model inside a directory but i have modified the path in auth.php.</p>
<p>Here is the route that domain1 points to:</p>
<p><a href="http://domain2.com/">http://domain2.com/</a>{{$role}}/{{$route}}/singlesignon/{{$token}}</p>
<p>This is then picked up by verifySingleSignOn method inside the loginController which takes in the role, route that the user came in from other domain and the token. The user is then redirected to the same routes, but on domain2. Here i can successfully recieve the user id before manually logging in.</p>
<pre><code>public function verifySingleSignOn($role, $route, $token)
{
// Fetch Single Signon
$userRepository = new UserRepository();
$user = $userRepository->checkForSingleSignOnToken($token, ['id']);
// Check if Token Exists
if (isset($user->id) && is_int($user->id) && $user->id != 0) {
// Manually Logging a user (Here is successfully recieve the user id)
$loggedInUser = Auth::loginUsingId($user->id);
if (!$loggedInUser) {
// If User not logged in, then Throw exception
throw new Exception('Single SignOn: User Cannot be Signed In');
}
$redirectTo = $role . '/' . $route;
return redirect($redirectTo);
} else {
return Auth::logout();
}
}
</code></pre>
<p>Then i have this GlobalAdminAuth middleware</p>
<pre><code> // Check if logged in
if( Auth::Check() ){
$user = Auth::User();
// Check if user is active and is a globaladmin
if( !$user->isGlobalAdmin() || !$user->isActive() ){
return redirect()->guest('login');
}
}else{
return redirect()->guest('login');
}
return $next($request);
</code></pre>
<p>Now the first time everything works fine and the user moves through the middleware successfully . but the second time the else statement is triggered.</p>
<p><strong>Edit: Code for checkForSingleSignOnToken</strong></p>
<pre><code>public function checkForSingleSignOnToken($token, $columns = array('*'))
{
return User::where('single_signon', $token)->first($columns);
}
</code></pre> | 0 |

<pre><code>' Write the image to file
Dim myFile As String
myFile = Application.ActiveWorkbook.Path & "\temp.png"
Open myFile For Output As #1
Write #1, vLogo
Close #1
' Insert the image
Sheets("Sheet1").Pictures.Insert (Application.ActiveWorkbook.Path & "\temp.png")
' Delete the temp file
Kill Application.ActiveWorkbook.Path & "\temp.png"

C# async within an action | <p>I would like to write a method which accept several parameters, including an action and a retry amount and invoke it.</p>
<p>So I have this code:</p>
<pre><code>public static IEnumerable<Task> RunWithRetries<T>(List<T> source, int threads, Func<T, Task<bool>> action, int retries, string method)
{
object lockObj = new object();
int index = 0;
return new Action(async () =>
{
while (true)
{
T item;
lock (lockObj)
{
if (index < source.Count)
{
item = source[index];
index++;
}
else
break;
}
int retry = retries;
while (retry > 0)
{
try
{
bool res = await action(item);
if (res)
retry = -1;
else
//sleep if not success..
Thread.Sleep(200);
}
catch (Exception e)
{
LoggerAgent.LogException(e, method);
}
finally
{
retry--;
}
}
}
}).RunParallel(threads);
}
</code></pre>
<p>RunParallel is an extention method for Action, its look like this:</p>
<pre><code>public static IEnumerable<Task> RunParallel(this Action action, int amount)
{
List<Task> tasks = new List<Task>();
for (int i = 0; i < amount; i++)
{
Task task = Task.Factory.StartNew(action);
tasks.Add(task);
}
return tasks;
}
</code></pre>
<p>Now, the issue: The thread is just disappearing or collapsing without waiting for the action to finish.</p>
<p>I wrote this example code:</p>
<pre><code>private static async Task ex()
{
List<int> ints = new List<int>();
for (int i = 0; i < 1000; i++)
{
ints.Add(i);
}
var tasks = RetryComponent.RunWithRetries(ints, 100, async (num) =>
{
try
{
List<string> test = await fetchSmthFromDb();
Console.WriteLine("#" + num + " " + test[0]);
return test[0] == "test";
}
catch (Exception e)
{
Console.WriteLine(e.StackTrace);
return false;
}
}, 5, "test");
await Task.WhenAll(tasks);
}
</code></pre>
<p>The <code>fetchSmthFromDb</code> is a simple Task> which fetches something from the db and works perfectly fine when invoked outside of this example.</p>
<p>Whenever the <code>List<string> test = await fetchSmthFromDb();</code> row is invoked, the thread seems to be closing and the <code>Console.WriteLine("#" + num + " " + test[0]);</code> not even being triggered, also when debugging the breakpoint never hit.</p>
<p><strong>The Final Working Code</strong></p>
<pre><code>private static async Task DoWithRetries(Func<Task> action, int retryCount, string method)
{
while (true)
{
try
{
await action();
break;
}
catch (Exception e)
{
LoggerAgent.LogException(e, method);
}
if (retryCount <= 0)
break;
retryCount--;
await Task.Delay(200);
};
}
public static async Task RunWithRetries<T>(List<T> source, int threads, Func<T, Task<bool>> action, int retries, string method)
{
Func<T, Task> newAction = async (item) =>
{
await DoWithRetries(async ()=>
{
await action(item);
}, retries, method);
};
await source.ParallelForEachAsync(newAction, threads);
}

How to set ANDROID_NDK_HOME so that Android Studio does not ask for ndk location? | <p>My ndk is located at <code>C:\Users\X\AppData\Local\Android\ndk</code>. Now each time I create a new native android project and try to import into Android Studio, it asks me for the location of ndk. I can manually set the ndk in <code>local.properties</code> also.</p>
<p>But I am looking for a way to set this ndk path, so that Android Studio does not ask me to set this path each time.</p>
<p>I have already set <strong>ANDROID_NDK_HOME</strong>, as well as <strong>NDK_HOME</strong> in system environment variable on Windows 10 machine, but Android Studio is still not able to find it. I have restarted my machine as well, still no luck.</p>
<p>I have not tried it on mac, but your answers for both windows and mac are welcome.</p> | 0 |

Function chaining in Python | <p>On <a href="https://www.codewars.com/" rel="noreferrer">Codewars.com</a> I encountered the following task:</p>
<blockquote>
<p>Create a function <code>add</code> that adds numbers together when called in succession. So <code>add(1)</code> should return <code>1</code>, <code>add(1)(2)</code> should return <code>1+2</code>, ...</p>
</blockquote>
<p>While I'm familiar with the basics of Python, I've never encountered a function that is able to be called in such succession, i.e. a function <code>f(x)</code> that can be called as <code>f(x)(y)(z)...</code>. Thus far, I'm not even sure how to interpret this notation.</p>
<p>As a mathematician, I'd suspect that <code>f(x)(y)</code> is a function that assigns to every <code>x</code> a function <code>g_{x}</code> and then returns <code>g_{x}(y)</code> and likewise for <code>f(x)(y)(z)</code>.</p>
<p>Should this interpretation be correct, Python would allow me to dynamically create functions which seems very interesting to me. I've searched the web for the past hour, but wasn't able to find a lead in the right direction. Since I don't know how this programming concept is called, however, this may not be too surprising.</p>
<p>How do you call this concept and where can I read more about it?</p> | 0 |

Javascript function document.createElement(tagName[, options]) doesn't work as intended | <p>I need to create <code><a href="http://someurl.com"></a></code> element <strong>in one js code line</strong></p>
<p>this doesn't work:</p>
<p><code>var gg = document.createElement("a", {href : "http://someurl.com"})</code></p>
<p>this result in: <code><a is="[object Object]"></a></code></p>
<p>Thought MDN says:
<code>var element = document.createElement(tagName[, options]);</code></p>
<p>options is an optional ElementCreationOptions object. If this object is defined and has an <code>is</code> property, the <code>is</code> attribute of the created element is initalized with the value of this property. If the object has no <code>is</code> property, the value is null.
<a href="https://developer.mozilla.org/en-US/docs/Web/API/Document/createElement" rel="noreferrer">https://developer.mozilla.org/en-US/docs/Web/API/Document/createElement</a></p>
<p>is this ElementCreationOptions object some sort of exotic object? I tried many various combinations around this object but nothing works and always in results i see that strange <code>is</code> property! I also found it in specification: <a href="https://www.w3.org/TR/custom-elements/#attr-is" rel="noreferrer">https://www.w3.org/TR/custom-elements/#attr-is</a> but no idea how it actually works.</p>

Is it still relevant to specify width and heigth attribute on images in HTML? | <p>I found <a href="https://stackoverflow.com/questions/1247685/should-i-specify-height-and-width-attributes-for-my-imgs-in-html">a similar question here</a>, with the answer: "<em>you should always define the width and height in the image tag</em>." But it is from 2009.</p>
<p>In the meantime, many things has changed on frontend. We are all doing responsive page design now, for many devices and sizes simultaneously (mobile, tablet, desktop...).</p>
<p>So, I wonder is it still necessary to specify the width and height attributes, and for what reason (for responsive, page speed, SEO...)?</p> | 0 |
Why does pip freeze list "pkg-resources==0.0.0"? | <p>On Ubuntu 16.04 with virtualenv 15.0.1 and Python 3.5.2 (both installed with <code>apt</code>) when I create and activate new Python virtual environment with</p>
<pre class="lang-sh prettyprint-override"><code>virtualenv .virtualenvs/wtf -p $(which python3) --no-site-packages
source .virtualenvs/wtf/bin/activate
</code></pre>
<p>I get the following output:</p>
<pre class="lang-none prettyprint-override"><code>Already using interpreter /usr/bin/python3
Using base prefix '/usr'
New python executable in /home/das-g/.virtualenvs/wtf/bin/python3
Also creating executable in /home/das-g/.virtualenvs/wtf/bin/python

</code></pre>
<p>Indeed <code>pip freeze --all</code> lists these 4 packages:</p>
<pre><code>pip==8.1.2
pkg-resources==0.0.0
setuptools==25.2.0
wheel==0.29.0
</code></pre>
<p>Though, I'd expect <code>pip freeze</code> (without <code>--all</code>) to omit these implicitly installed packages. It does omit some of them, but not <code>pkg-resources</code>:</p>
<pre><code>pkg-resources==0.0.0
</code></pre>
<p>(Same btw. for <code>pip freeze --local</code>)</p>
<p>While this is consistent with the help text</p>
<pre class="lang-sh prettyprint-override"><code>$> pip freeze --help | grep '\--all'
--all Do not skip these packages in the output: pip, setuptools, distribute, wheel
</code></pre>
<p>having <code>pkg-resources</code> in the <code>pip freeze</code> output doesn't seem very useful and might even be harmful. (I suspect it's why running <code>pip-sync</code> from <a href="https://github.com/nvie/pip-tools">pip-tools</a> uninstalls pkg-resources from the virtual environment, subtly breaking the environment thereby.) <strong>Is there any good reason why <code>pip freeze</code> lists <code>pkg-resources</code> instead of omitting it, too?</strong> As far as I remember, it didn't list it on Ubuntu 14.04 (with Python 3.4).</p> | 0 |
Python: Append a list with a newline | <p>In the following code I am updating a list with two items by appending to it from within a for loop. I need a newline to be added after appending each string but I can't seem to be able to do it.</p>
<p>I thought it would have been:</p>
<pre><code>lines = []
for i in range(10):
line = ser.readline()
if line:
lines.append(line + '\n') #'\n' newline
lines.append(datetime.now())
</code></pre>
<p>But this only adds the '\n' as a string. I have also tried the same without without the quotes, but no luck.</p>
<p>I am getting this:</p>
<pre><code>['leftRaw; 928090; 0; 0.00; 0.00; 0.00; 0.00; 0.00; 0.00; 0.00; 0.00;\n', datetime.datetime(2016, 8, 25, 23, 48, 4, 517000), '\r\x00rightRaw; 928090; 0; 0.00; 0.00; 0.00; 0.00; 0.00; 0.00; 0.00; 0.00;\n', datetime.datetime(2016, 8, 25, 23, 48, 4, 519000), '\r\x00leftRaw; 928091; 0; 0.00; 0.00; 0.00; 0.00; 0.00; 0.00)]

In Git, list names of branches with unpushed commits | <p>Given a project with several local branches, each tracking some remote branch, is there a command that lists all branches that have unpushed commits? (That is, even if none of those branches are checked out.)</p>
<p>I don't want to see the commits themselves, nor do I want to see branches that are up-to-date, I just want to see which branches are ahead of their remotes.</p>
<p>I have tried <code>git log --branches --not --remotes --simplify-by-decoration --decorate --oneline</code>, but it doesn't seem to show what I need. Running it on my current repo gives no output, but running <code>git status</code> on my current branch shows <code>Your branch is ahead of 'origin/branchname' by 2 commits.</code></p>
<p><code>git for-each-ref --format="%(refname:short) %(push:track)" refs/heads</code> and <code>git branch -v</code> both show branches that are up to date as well as ones that need pushing. However, they <em>do</em> both show my current branch as <code>[ahead 2]</code>.</p>
<p>Other commands I have found eg. <code>git log @{u}..</code>, <code>git cherry -v</code> list the commits themselves, not the branches.</p>
<p><strong>Side question:</strong> why would the output from <code>git log --branches --not --remotes --simplify-by-decoration --decorate --oneline</code> not include branches that <code>git branch -v</code> shows as ahead? Isn't the former command just looking at which <code>refs/heads</code> do not correspond to a known remote; so wouldn't a branch listed as <code>[ahead 2]</code> meet this criteria?</p> | 0 |
MongoDB Date range query for past hour | <p>I'm trying to write MongoDB query which will be return data from one hour ago.

System.OutOfMemoryException occurs frequently after Upgrading SQL Server 2016 to version 13.0.15700.28 | <p>I am running Windows 10 Pro 64 bit on a dev box that has multiple monitors, 16 gigs DDR4 RAM, 4 Ghz I7, GTX 970. I run SQL Management Studio with SQL Server 2016 Developer Edition along with VS 2015 Enterprise Update 3. </p>
<p>Yesterday I upgraded Sql Management Studio 2016 to 13.0.15700.28 and it was like a poison pill for my machine. Now after an hour or two it will throw an out of memory except:</p>
<blockquote>
<p>An error occurred while executing batch. Error message is: Exception
of type 'System.OutOfMemoryException' was thrown</p>

<p>I was doing some new table and procedure creation for new objects to an existing development system. And this just occurs out of the blue for no rhyme or reason. It also appears to be a partial blocking error for SSMS as it now freezes the system and attempts to bring up a connection dialog window like I am first starting SSMS and attempting to connect to a datasource. Thus far it goes to a crawl until I kill it from task manager. I am also running Redgate's SQL Prompt 7.2.0.241. Things I have tried:</p>
<ol>
<li>Attempted to keep tabs under five at a time and close them as I am done.</li>
<li>Do not break off the tabs from one screen to another.</li>
<li>Turn off Redgate and see if it is the culprit</li>
<li>Check memory use as I go</li>
</ol>
<p>I know it blew up last night as I came into work and SSMS let me know it had crashed. This may be an MS bug but there may be a bug in Redgate or some other config I have so I thought it best to ask SO and see what others have seen. This build of SSMS is as of 8/15/2016 so it is very new.</p>

<p>If you have this happen to you or know a potential fix, please let me know. At this point if I have to do heavy SQL work coming up I am thinking of downgrading at this point. Again I am on Windows 10 64 bit machine and this only happened after upgrading to the most recent SSMS build.</p>

<p>Posted by Microsoft on 8/29/2016 at 10:21 AM turns out there's a
thread leak in a utility class. The number of threads leaked will be
proportional to the number of registered servers you have, among other
things. A fix is coming in the next release</p>

<p>I downgraded as doing work got more important than figuring out what was blowing up. Downgrade for me is working fine now. I gave MS SQL dumps so hopefully they can get a new build in the coming weeks. If you are curious I am on version 13.0.15600.2 and stable thus far as I downgraded two days ago.</p> | 0 |

How to check if, elif, else conditions at the same time in django template | <p>I have 3 category in category field. I want to check it in django template and assign appropirte urls for 3 distinct category.</p>
<p>I tried:</p>
<pre><code>{% for entry in entries %}
{% if entry.category == 1 %}
<a href="{% url 'member:person-list' %}"><li>{{ entry.category }}</li></a>
{% elif entry.category == 2 %}
<a href="{% url 'member:execomember-list' %}"><li>{{ entry.category}}</li></a>
{% else %}
<a href="{% url 'member:lifemember-list' %}"><li>{{ entry.category}}</li></a>
{% endif %}
{% empty %}
<li>No recent entries</li>
{% endfor %}
</code></pre>
<p>But I know python only check first matching condition with if. Therefore it gave only one desired result. How do I get all three entries with their correct links?</p>
<p><strong>Edit:</strong></p>
<p>Though python only check first matching if condition, when use elif within for loop it check each condition until endfor loop. Therefore my answer below worked fine. </p> | 0 |

How can I recreate a fragment? | <p>I'm using a widget called SwipeRefreshLayout, to refresh my fragment when someone pushes the view.</p>
<p>To recreate the activity I have to use:</p>

Bundle savedInstanceState) {
final View view = inflater.inflate(R.layout.fragment_lobby, container, false);

mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
getActivity().recreate();

MariaDB Insert BLOB Image | <p><strong>What I want to do?</strong> </p>
<ul>
<li>I want to insert a picture into a MariaDB database using the command line, using the LOAD_FILE fuction.</li>
</ul>
<p><strong>What's wrong?</strong></p>
<ul>
<li>I always get a NULL return.</li>
<li>I <strong>don't</strong> want a solution like: This is bad style and I haven't seen this so far - try to store the full path! I <strong>want</strong> to store this picture in this database and <strong>not</strong> the path.</li>
</ul>
<p><strong>System</strong></p>
<ul>
<li><p><em>mysql</em> Ver 15.1 Distrib 10.1.17-MariaDB, for Linux (x86_64) using readline 5.1</p></li>
<li><p><em>ArchLinux</em> 4.7.2-1-ARCH</p></li>
<li><p>A picture called <em>Test.jpg</em> (817KB) under <code>/home/user/Blob/Test.jpg</code>, <code>/tmp/Test.jpg</code> and even under <code>/var/lib(mysql/images/Test.jpg</code> </p></li>
<li><p>The picture belongs to the user and group mysql and has every permission I could imagine</p>
<pre><code>-rwxrwxrwx 1 mysql mysql 836508 20. Feb 2016 Test.jpg
</code></pre></li>
<li>I tested several users i.e. <em>mysql</em> and <em>root</em></li>
</ul>
<p><strong>Database</strong></p>
<p>I have created a database called <em>Blobtest</em> with a table called <em>Test</em> with a Blob and a Longblob variable. </p>

<pre><code>INSERT INTO Test VALUES (1, LOAD_FILE('/home/user/Blob/Test.jpg'), LOAD_FILE('/home/user/Blob/Test.jpg'));
</code></pre>
<p><strong>Approach to solving this problem</strong></p>
<p>I followed the instructions at this link <a href="https://stackoverflow.com/questions/18069054/mysql-load-file-loads-null-values">MySQL LOAD_FILE() loads null values</a></p>
<ul>
<li>I have execute permission on the parent directory</li>
<li>The FILE privilege is explicily granted. (GRANT FILE on . TO mysql@localhost)</li>
<li>I have flushed privileges</li>
<li>I have logged out and logged back in</li>
<li>I have tested several directories, belonging to <em>mysql</em> or <em>user</em> via <code>chmod</code> and <code>chown</code> command</li>
<li><code>SHOW VARIABLES LIKE 'max_allowed_packet';</code> is set to 16 MB or 16777216, picture is 817KB <em>big</em></li>
<li><code>select HEX(LOAD_FILE('/home/user/Blob/Test.jpg'));</code> returns NULL</li>
</ul>
<p><strong>Solutions?</strong></p>
<p>I don't know if this is a bug in MariaDB or if I'm the only one who has this problem.
To point this out again: I <strong>want</strong> to store the picture within this database. I <strong>don't</strong> want to store the path. This is an experiment, I have to store the picture in the database.</p>

Custom View - self.frame is not correct? | <p>So I have a custom UIView class</p>
<pre><code>class MessageBox: UIView {
override init(frame: CGRect) {
super.init(frame: frame)
createSubViews()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
createSubViews()
}
func createSubViews() {
let testView = UIView(frame: self.frame)
testView.backgroundColor = UIColor.brown
self.addSubview(testView)
}
}
</code></pre>
<p>I added a UIView inside the storyboard and gave it some constraints:</p>
<blockquote>
<p>100 from the top (superview), 0 from the left and right, height is 180</p>
</blockquote>
<p>But when I run the app the brown subview I created in the code is way to big. I printed <code>self.frame</code> in my custom view and it turns out that the frame is <code>(0,0,1000,1000)</code>. But why? I set constraints, it should be something like <code>(0,0,deviceWith, 180)</code>.</p>

RecyclerView with GridLayoutManager inside RecyclerView with LinearLayoutManager | <p>I am basically trying the achieve this design principle (<a href="https://material.google.com/components/cards.html#cards-actions" rel="nofollow noreferrer">from Google's Material Design</a>):
<a href="https://i.stack.imgur.com/bz59T.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bz59T.png" alt="enter image description here"></a>
Thus I've made a parent <code>RecyclerView</code> with a <code>LinearLayoutManager</code>, then in the <code>RecyclerView</code> adapter, I've put the child <code>RecyclerView</code> with a <code>GridLayoutManager</code> for the "rich media" section (Action area 2). Everything works fine, except for the fact that I've set the internal <code>RecyclerView</code> grid to have a <code>match_parent</code> width and a <code>wrap_content</code> height, but it won't calculate the size of the content properly, seemingly leaving it at 0 & thus hidden. If I set the child <code>RecyclerView</code> to a specific height, the items show within, but are then of course cut off at the bottom.
Others seem to have come across this problem, <a href="https://stackoverflow.com/questions/32011995/how-to-have-a-listview-recyclerview-inside-a-parent-recyclerview-i-have-a-pare">but in their case, both have linear layouts</a>. (Also see <a href="https://stackoverflow.com/questions/34569217/how-to-add-a-recyclerview-inside-another-recyclerview">"Khay's" answer here</a>.)</p>
<p>Now my question is, how would one override the <code>onMeasure</code> method as "pptang" did in the accepted answer of the linked question above, but within a custom <code>GridLayoutManager</code> instead of a custom <code>LinearLayoutManager</code>? I haven't posted my code here, because it's essentially the identical to the one linked, only that I need to make a custom <code>GridLayoutManager</code> instead for the child <code>RecyclerView</code>, so that it measures correctly as "pptang's" answer states.</p>
<p>Otherwise, is there a better way than to use 1 RecyclerView inside a 2nd RecyclerView? Can only 1 RecyclerView populate an activity/fragment both with a list of the above <code>CardViews</code> and a grid of unique items within each <code>CardView</code>? </p> | 0 |
How to correctly configure the property "sonar.java.binaries"? | <p>We are using SonarQube 5.1.2 using Ant runner 2.2 and Java pluging 3.12 for the analysis. I can succesfully analyse my project. I just keep getting this error:</p>
<pre><code>Java bytecode has not been made available to the analyzer. The org.sonar.java.bytecode.visitor.DependenciesVisitor@d678716, org.sonar.java.checks.unused.UnusedPrivateMethodCheck@58e28efd, CycleBetweenPackages rule are disabled.
</code></pre>
<p>So I need to configure my sonar.java.binaries and sonar.java.test.binaries properties (following <a href="http://docs.sonarqube.org/display/PLUG/Java+Plugin+and+Bytecode" rel="noreferrer">http://docs.sonarqube.org/display/PLUG/Java+Plugin+and+Bytecode</a>). </p>
<p>Which I think I have done correctly:</p>
<pre><code><property name="project.dir" value="${basedir}/xalg.prj/h3_service_fo" />
<property name="sonar.java.binaries" location="${project.build.dir}/classes/main" />
<property name="sonar.java.test.binaries" value="${project.build.dir}/classes/test" />
</code></pre>
<p>Which resolve to the following valid directories for the above properties:</p>
<pre><code>basedir=D\:\\appl\\BuildAgent\\work\\H3\\src.prj\\java.prj
project.dir=D\:\\appl\\BuildAgent\\work\\H3\\src.prj\\java.prj/xalg.prj/h3_service_fo
sonar.java.binaries=D\:\\appl\\BuildAgent\\work\\H3\\src.prj\\java.prj\\xalg.prj\\h3_service_fo\\build\\classes\\main
sonar.java.test.binaries=D\:\\appl\\BuildAgent\\work\\H3\\src.prj\\java.prj/xalg.prj/h3_service_fo/build/classes/test
</code></pre>
<p>But I keep getting:</p>
<pre><code>Java bytecode has not been made available to the analyzer. The org.sonar.java.bytecode.visitor.DependenciesVisitor@d678716, org.sonar.java.checks.unused.UnusedPrivateMethodCheck@58e28efd, CycleBetweenPackages rule are disabled.
</code></pre>
<p>And for the life of me, I can not figure out what values I need to give the sonar.java.binaries and sonar.java.test.binaries properties. I even tried using sonar.binaries, which gave me the following output:</p>
<pre><code>Binary dirs: xalg.prj/h3_service_fo/build/classes
</code></pre>
<p>Which I did not get using either sonar.java.binaries or sonar.java.test.binaries. I also got:</p>
<pre><code>JavaClasspath initialization...
sonar.binaries and sonar.libraries are deprecated since version 2.5 of sonar-java-plugin, please use sonar.java.binaries and sonar.java.libraries instead
</code></pre>
<p>Which is to be expected for a deprecated property. But using the sonar.java.binaries property I did not get the "Binary dirs" line in my log.</p>
<p>Using sonar.java.binaries:</p>
<pre><code>Language is forced to java

<p>Versus using sonar.binaries:</p>

</code></pre>
<p>I also looked into the source code of SonarQube, SonarQube Java Plugin and the SonarQube Scanner for instances of either "Java bytecode has not been made available to the analyzer." or sonar.java.binaries. I found plenty on sonar.java.binaries, but nothing on "Java bytecode has not been made available to the analyzer." So I have no clue what conditions exactly trigger that error.</p>
<p>I also tried the following permutations on sonar.java.binaries:</p>
<pre><code><property name="sonar.java.binaries" location="${project.build.dir}/classes" />
<property name="sonar.java.binaries" location="${project.build.dir}/classes/main/nl" />
</code></pre>
<p>But that did nothing either.</p>

React Native, Android Log. | <p>Is there a way in react native to see the log from native (java) modules of android?</p>
<p>I'm using javas log module <a href="https://developer.android.com/reference/android/util/Log.html" rel="noreferrer">https://developer.android.com/reference/android/util/Log.html</a> - but I'm not getting anything from there. and to be honest I'm not sure how to use it if it's at all possible. atm there isn't much code - it's just </p>
<pre><code> Log.d("Notification","Notify App");
</code></pre>
<p>Because I want to see if I can see the notifications somewhere - I do know the java module is registered correctly as I'm calling other functions from it.</p>

Write col names while writing csv files in R | <p>What is the proper way to append col names to the header of csv table which is generated by <code>write.table</code> command?
For example <code>write.table(x, file, col.names= c("ABC","ERF"))</code> throws error saying <code>invalid col.names specification</code>.Is there way to get around the error, while maintaining the function header of <code>write.table</code>.</p>
<p>Edit:
I am in the middle of writing large code, so exact data replication is not possible - however, this is what I have done:
<code>write.table(paste("A","B"), file="AB.csv", col.names=c("A1","B1"))</code> , I am still getting this error <code>Error in write.table(paste("A","B"), file="AB.csv", col.names=c("A", : invalid 'col.names' specification.</code></p> | 0 |

How to set the row index name in R? (Like DF.index.name in Pandas) | <p><strong>How can I set the row index name in a <code>R</code> <code>data.frame</code> object?</strong> </p>

Failed to load resource: the server responded with a status of 415 (Unsupported Media Type) in Java RESTful web service call | <p>I have the following javascript in my test html page to send ajax requests to a java restful web service I built with netbeans (mostly auto generated by using 'Restful web services from database' function).
Here is the ajax query from my test html page:</p>
<pre><code>$(function(){
$('.message-button').on('click', function(e){
var resultDiv = $("#resultDivContainer");
$.ajax({
headers: { 'Accept': 'application/json',
'Content-Type': 'application/json'
},
'type': 'POST',
'url': 'http://localhost:8080/xxxAPI/api/activity',
'data': { "baseItemId": "2" },
'dataType':'json',
'success': function(data) {
var xmlstr = data.xml ? data.xml : (new XMLSerializer()).serializeToString(data);
$("#resultDivContainer").text(xmlstr);
},
'error': function(jqXHR, textStatus, errorThrown) {
alert(' Error in processing! '+textStatus + 'error: ' + errorThrown);
}
});
})
});
</code></pre>
<p>Also here is the part of my java code that accepts post requests:</p>
<pre><code>@POST
@Override
@Consumes({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
public void create(XxxxxActivity entity) {
super.create(entity);
}
</code></pre>
<p>When I request from the test page (for this version of the test page), I get this error: </p>
<blockquote>
<p>Failed to load resource: the server responded with a status of 415
(Unsupported Media Type)</p>
</blockquote>
<p>or this error:</p>
<blockquote>
<p>POST <a href="http://localhost:8080/xxxAPI/api/activity" rel="nofollow">http://localhost:8080/xxxAPI/api/activity</a> 415 (Unsupported
Media Type)</p>
</blockquote>
<p>So far I have tried making various changes to the ajax request as advised on similar questions on stackoverflow, including changing type to <code>jsonp</code>, putting json data in double quotes, adding headers and changing data type to xml. None of them have worked. </p>
<p>Also since I manage to get a response from the server at times, I wonder if the issue is with xml parsing in the java code. I believe a potential fix would be to add the jackson jar files, but I have no idea how to add them on netbeans as there is no lib folder in WEB_INF. </p>
<p>I would also like to know if there is any issue with the jquery ajax request. This issue has been bugging me for days.</p>
<p><strong>PS</strong>: Also note that GET requests from the browser work fine. I have not used maven in this project. </p> | 0 |

Apache CXF: A SOAP 1.2 message is not valid when sent to a SOAP 1.1 only endpoint | <p>first of all, I know that there are already some questions on SO about this topic but none of them solved my problem (or I am too stupid to understand them, that's a possibility as well).</p>
<p>So, I have a WSDL. From the WSDL I've generated a Java client using Eclipse CXF plugin. Now I'm doing this:</p>
<pre><code>JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
factory.setServiceClass(MyServiceInterface.class);
factory.setAddress("myEndpoint");
List<Interceptor<? extends Message>> interceptors = new ArrayList<Interceptor<? extends Message>>();
interceptors.add(new HeaderOutInterceptor());
factory.setOutInterceptors(interceptors);
MyServiceInterface service = (MyServiceInterface) factory.create();
</code></pre>
<p>The interceptor only adds an header to the requests I'm sending through the client:</p>
<pre><code>message.put(Message.CONTENT_TYPE, "application/soap+xml");
</code></pre>
<p>I'm adding this manually since by default the content type is text/xml and I get a 415 error.</p>
<p>The problem is that with this configuration I get this exception:</p>
<pre><code>org.apache.cxf.binding.soap.SoapFault: A SOAP 1.2 message is not valid when sent to a SOAP 1.1 only endpoint.

at org.apache.cxf.phase.PhaseInterceptorChain.doIntercept(PhaseInterceptorChain.java:308)
</code></pre>
<p>I've tried adding this annotation to the generated client interface:</p>
<pre><code>@BindingType(javax.xml.ws.soap.SOAPBinding.SOAP12HTTP_BINDING)
</code></pre>
<p>But nothing changed. Can anybody help me?</p>
<p><strong>EDIT</strong></p>
<p>I've added a cxf.xml file under the classpath. This is the content:</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>

What is a Blob used in Jquery | <p>I came across <code>blob</code> while searching some stuff in jQuery. Googled about it but could not exactly figure out what kind of concept it is.</p>

method: 'GET',
dataType: 'blob',
data: { report_type: report_type, start_date: start_date, end_date: end_date, date_type: date_type },

success: function(data) {
var blob=new Blob([data]);

link.download="Report_"+new Date()+".pdf";
link.click();
console.log("pdf printed");
}
});

<p>This code is working fine but printing empty pdf without the content either static or dynamic. But with a strange behaviour. I.e. if the dynamic data calculated is too big, it is generating multiple pages.</p>
<p>I just want to figure out the concept of <code>blob</code> so that I can figure out myself what this piece of code is doing and how does <code>blob</code> work.</p>

Can a Static method access a private method of the same class? | <p>I have this question because of the singleton/named constructor. In both cases, the real constructors are protected or private, neither of which can be accessed from outside. </p>
<p>For example, a short named constructor is this:</p>
<pre><code> class A
{
public:
static A createA() { return A(0); } // named constructor
private:
A (int x);
};
int main(void)
{
A a = A::createA();
}
</code></pre>
<p>I thought static method can only access static data member, or access private data/method via an existing object.
However, in the above code, private constructor <code>A()</code> isn't static, and at the time it is being called, no object exists either.
So the only explanation I can think of is that static method can access non-static private method of the same class. Can anyone please either affirm or negate my thought, possibly with some lines of explanations? </p>
<p>I apologize if this is too trivial however the key words are too common and I wasn't able to find an answer in dozens of google pages. Thanks in advance.</p> | 0 |

Range(Selection).Offset(0, -7).Value = "=IF(LEFT(RC9,8)=Mapping!R8C1,""YES"",""NO"")"
Else
End If
</code></pre>
<p>This is part of a larger code where I am trying to have each visible cell in Column H compared to a cell on the mapping sheet and if correct then the if statement will be added into column A.</p>
<p>I am having a similar issue when attempting to use cell.value in another if statement where I include an AND statement, see below. Same type of FOR statement for Column I in this case. Comparing each value in column I to two different cells on the mapping sheet and if correct the changing column A's value to YES. Both lines break on the 3rd line and the second code breaks on the second line as well.</p>
<pre><code>For Each cell In Range("I2", Selection.End(xlDown).End(xlDown).End(xlUp)).SpecialCells(xlCellTypeVisible)
If cell.Value = Range(Sheets("Mapping").Cells(4, x)).Value And cell.Value = Range(Sheets("Mapping").Cells(9, 1)).Value Then
Range(Selection).Offset(0, -7).Value = "YES"
Else
'do nothing
</code></pre>
<p>Any help would be greatly appreciated.
Thanks.</p> | 0 |
