Without external variables:

       $('.element').bind('mousewheel', function(e, d) {
            if((this.scrollTop === (this.scrollHeight - this.offsetHeight) && d < 0)
                || (this.scrollTop === 0 && d > 0)) {
                e.preventDefault();
            }
        });

When you create the emulator, you need to choose properties CPU/ABI is Intel Atom (installed it in SDK manager )

They have wrapped most stuff need to solve your problem, one of the tests looks like this:

String filename = CSSURLEmbedderTest.class.getResource("folder.png").getPath().replace("%20", " ");
String code = "background: url(folder.png);";

StringWriter writer = new StringWriter();
embedder = new CSSURLEmbedder(new StringReader(code), true);
embedder.embedImages(writer, filename.substring(0, filename.lastIndexOf("/")+1));

String result = writer.toString();
assertEquals("background: url(" + folderDataURI + ");", result);

That is, you are referencing an image, but instead of providing an external url, the png image data is in the url itself, embedded in the style sheet. data:image/png;base64 tells the browser that the data is inline, is a png image and is in this case base64 encoded. The encoding is needed because png images can contain bytes that are invalid inside a HTML document (or within the HTTP protocol even).

"Employed Russian" is among the best answer, and I think all other suggested answer may not work. The reason is simply because when an application is first created, all its the APIs it needs are resolved at compile time. Using "ldd" u can see all the statically linked dependencies:

ldd /usr/lib/firefox/firefox
    linux-vdso.so.1 =>  (0x00007ffd5c5f0000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f727e708000)
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f727e500000)
    libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f727e1f8000)
    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f727def0000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f727db28000)
    /lib64/ld-linux-x86-64.so.2 (0x00007f727eb78000)
    libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f727d910000)

But at runtime, firefox will also load many other dynamic libraries, eg (for firefox) there are many "glib"-labelled libraries loaded (even though statically linked there are none):

 /usr/lib/x86_64-linux-gnu/libdbus-glib-1.so.2.2.2
 /lib/x86_64-linux-gnu/libglib-2.0.so.0.4002.0
 /usr/lib/x86_64-linux-gnu/libavahi-glib.so.1.0.2

Manytimes, you can see names of one version being soft-linked into another version. Eg:

lrwxrwxrwx 1 root root     23 Dec 21  2014 libdbus-glib-1.so.2 -> libdbus-glib-1.so.2.2.2
-rw-r--r-- 1 root root 160832 Mar  1  2013 libdbus-glib-1.so.2.2.2

This therefore means different version of "libraries" exists in one system - which is not a problem as it is the same file, and it will provide compatibilities when applications have multiple versions dependencies.

Therefore, at the system level, all the libraries are almost interdependent on one another, and just changing the libraries loading priority via manipulating LD_PRELOAD or LD_LIBRARY_PATH will not help - even it can load, runtime it may still crash.

Best alternative is chroot (mentioned by ER briefly): but for this you will need to recreate the entire environment in which is the original binary execute - usually starting from /lib, /usr/lib/, /usr/lib/x86 etc. You can either use "Buildroot", or YoctoProject, or just tar from an existing Distro environment. (like Fedora/Suse etc).

I tried the _JAVA_OPTIONS thing but it wasn't working for me still.

In the end, what worked for me was the following:

• Launching studio64.exe instead of the studio.exe(I've got a 64-bits machine).
• Add/Change the following values in "studio64.exe.vmoptions":

-Xms2048m_x000D_
-Xmx2048m_x000D_
-XX:MaxPermSize=1024m_x000D_
-XX:+CMSClassUnloadingEnabled_x000D_
-XX:+CMSPermGenSweepingEnabled _x000D_
-XX:+HeapDumpOnOutOfMemoryError_x000D_
-Dfile.encoding=utf-8

Java code:

public class MapActivity extends FragmentActivity implements LocationListener  {

    GoogleMap googleMap;
    LatLng myPosition;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_map);

        // Getting reference to the SupportMapFragment of activity_main.xml
        SupportMapFragment fm = (SupportMapFragment)
        getSupportFragmentManager().findFragmentById(R.id.map);

        // Getting GoogleMap object from the fragment
        googleMap = fm.getMap();

        // Enabling MyLocation Layer of Google Map
        googleMap.setMyLocationEnabled(true);

        // Getting LocationManager object from System Service LOCATION_SERVICE
        LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

        // Creating a criteria object to retrieve provider
        Criteria criteria = new Criteria();

        // Getting the name of the best provider
        String provider = locationManager.getBestProvider(criteria, true);

        // Getting Current Location
        Location location = locationManager.getLastKnownLocation(provider);

        if (location != null) {
            // Getting latitude of the current location
            double latitude = location.getLatitude();

            // Getting longitude of the current location
            double longitude = location.getLongitude();

            // Creating a LatLng object for the current location
            LatLng latLng = new LatLng(latitude, longitude);

            myPosition = new LatLng(latitude, longitude);

            googleMap.addMarker(new MarkerOptions().position(myPosition).title("Start"));
        }
    }
}

You will get your current location in a blue circle.

Steps:

1. Navigate to your project folder and open the /app sub-folder.

2. Paste the .json file here.

3. Rebuild the project.

as simple as that: echo '<a href="'.$link_address.'">Link</a>';

Here is some good overview of .NET impersonation concepts.

• Michiel van Otegem: WindowsImpersonationContext made easy
• WindowsIdentity.Impersonate Method (check out the code samples)

Basically you will be leveraging these classes that are out of the box in the .NET framework:

• WindowsImpersonationContext
• WindowsIdentity

The code can often get lengthy though and that is why you see many examples like the one you reference that try to simplify the process.

The solution provided by Rashack does not work for value types (int, enums, etc.) unfortunately.

For it to work with any type of property, this is the solution I found:

public static Expression<Func<T, object>> GetLambdaExpressionFor<T>(this string sortColumn)
    {
        var type = typeof(T);
        var parameterExpression = Expression.Parameter(type, "x");
        var body = Expression.PropertyOrField(parameterExpression, sortColumn);
        var convertedBody = Expression.MakeUnary(ExpressionType.Convert, body, typeof(object));

        var expression = Expression.Lambda<Func<T, object>>(convertedBody, new[] { parameterExpression });

        return expression;
    }

I guess ssh is the best secured way for this, for example :

ssh -OPTIONS -p SSH_PORT user@remote_server "remote_command1; remote_command2; remote_script.sh"  

where the OPTIONS have to be deployed according to your specific needs (for example, binding to ipv4 only) and your remote command could be starting your tomcat daemon.

Note:
If you do not want to be prompt at every ssh run, please also have a look to ssh-agent, and optionally to keychain if your system allows it. Key is... to understand the ssh keys exchange process. Please take a careful look to ssh_config (i.e. the ssh client config file) and sshd_config (i.e. the ssh server config file). Configuration filenames depend on your system, anyway you'll find them somewhere like /etc/sshd_config. Ideally, pls do not run ssh as root obviously but as a specific user on both sides, servers and client.

Some extra docs over the source project main pages :

Why is it that you need to place columns you create yourself (for example "select 1 as number") after HAVING and not WHERE in MySQL?

WHERE is applied before GROUP BY, HAVING is applied after (and can filter on aggregates).

In general, you can reference aliases in neither of these clauses, but MySQL allows referencing SELECT level aliases in GROUP BY, ORDER BY and HAVING.

And are there any downsides instead of doing "WHERE 1" (writing the whole definition instead of a column name)

If your calculated expression does not contain any aggregates, putting it into the WHERE clause will most probably be more efficient.

I'm not sure if Chrome has added this feature since the last answer, but I was able to view the json response by...

• opening developer tools in the browser while on the page with the request
• submitting the request
• in developer tools - "Console" tab - click on the "Object" tree under the resource to expand

...I was able to view the response as a readable hierarchy that showed what to ask for and what is returned. (Neither Network or Resources tab had anything helpful that I was able to find.)

Happy requesting!

I'd start by the distinction that exists in Scala between def, val and var.

• def - defines an immutable label for the right side content which is lazily evaluated - evaluate by name.

• val - defines an immutable label for the right side content which is eagerly/immediately evaluated - evaluated by value.

• var - defines a mutable variable, initially set to the evaluated right side content.

Example, def

scala> def something = 2 + 3 * 4 
something: Int
scala> something  // now it's evaluated, lazily upon usage
res30: Int = 14

Example, val

scala> val somethingelse = 2 + 3 * 5 // it's evaluated, eagerly upon definition
somethingelse: Int = 17

Example, var

scala> var aVariable = 2 * 3
aVariable: Int = 6

scala> aVariable = 5
aVariable: Int = 5

According to above, labels from def and val cannot be reassigned, and in case of any attempt an error like the below one will be raised:

scala> something = 5 * 6
<console>:8: error: value something_= is not a member of object $iw
       something = 5 * 6
       ^

When the class is defined like:

scala> class Person(val name: String, var age: Int)
defined class Person

and then instantiated with:

scala> def personA = new Person("Tim", 25)
personA: Person

an immutable label is created for that specific instance of Person (i.e. 'personA'). Whenever the mutable field 'age' needs to be modified, such attempt fails:

scala> personA.age = 44
personA.age: Int = 25

as expected, 'age' is part of a non-mutable label. The correct way to work on this consists in using a mutable variable, like in the following example:

scala> var personB = new Person("Matt", 36)
personB: Person = Person@59cd11fe

scala> personB.age = 44
personB.age: Int = 44    // value re-assigned, as expected

as clear, from the mutable variable reference (i.e. 'personB') it is possible to modify the class mutable field 'age'.

I would still stress the fact that everything comes from the above stated difference, that has to be clear in mind of any Scala programmer.

With a recent nightly, you can do this:

let my_int = from_str::<int>(&*my_string);

What's happening here is that String can now be dereferenced into a str. However, the function wants an &str, so we have to borrow again. For reference, I believe this particular pattern (&*) is called "cross-borrowing".

$("#id").off().on("click", function() {

});

Worked for me.

$("#id").off().on("click", function() {

});

In Java, according to the JSSE Reference Guide, there is no default for the keystore, the default for the truststore is "jssecacerts, if it exists. Otherwise, cacerts".

A few applications use ~/.keystore as a default keystore, but this is not without problems (mainly because you might not want all the application run by the user to use that trust store).

I'd suggest using application-specific values that you bundle with your application instead, it would tend to be more applicable in general.

I had this issue with Xcode 4.2.1.

For me it was nothing to do with Entitlements file, or Ad-hoc...

I was returning to and old project, and I'd forgotten to add my new iPhone to the provision.

Silly mistake, but also a silly corresponding error message... :-/

I advise you to go with Scanner instead of DataInputStream. Scanner is specifically designed for this purpose and introduced in Java 5. See the following links to know how to use Scanner.

• Java Documentation
• Java Tutorial

Example

Scanner s = new Scanner(System.in);
System.out.println(s.nextInt());
System.out.println(s.nextInt());
System.out.println(s.next());
System.out.println(s.next());

Here is a simple function for converting a byte buffer to string:

public String byteBufferToString(ByteBuffer bufferData) {
    byte[] buffer = new byte[bufferData.readableByteCount()];
    // read bufferData and insert into buffer 
    data.read(buffer);
    // CharsetUtil supports UTF_16, ASCII, and many more
    String text = new String(buffer, CharsetUtil.UTF_8);
    System.out.println("Text: "+text);
    return text;
}

The user543 answer is perfect

<activity
        android:name="first Activity Name"
        android:theme="@android:style/Theme.Translucent.NoTitleBar" >
 <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
 </activity>

But:

You'r LAUNCHER Activity must extands Activity, not AppCompatActivity as it came by default!

The way to do this is near the top of the man page

grep -i -A 10 'error data'

adding following to application.rb works

 config.time_zone = 'Eastern Time (US & Canada)'
 config.active_record.default_timezone = :local # Or :utc

I wanted to save Recycler View's scroll position when navigating away from my list activity and then clicking the back button to navigate back. Many of the solutions provided for this problem were either much more complicated than needed or didn't work for my configuration, so I thought I'd share my solution.

First save your instance state in onPause as many have shown. I think it's worth emphasizing here that this version of onSaveInstanceState is a method from the RecyclerView.LayoutManager class.

private LinearLayoutManager mLayoutManager;
Parcelable state;

        @Override
        public void onPause() {
            super.onPause();
            state = mLayoutManager.onSaveInstanceState();
        }

The key to getting this to work properly is to make sure you call onRestoreInstanceState after you attach your adapter, as some have indicated in other threads. However the actual method call is much simpler than many have indicated.

private void someMethod() {
    mVenueRecyclerView.setAdapter(mVenueAdapter);
    mLayoutManager.onRestoreInstanceState(state);
}

0 */6 * * * command

This will be the perfect way to say 6 hours a day.

Your command puts in for six minutes!

I dont know about XamGrid but that's what i'll do with a standard wpf DataGrid:

<DataGrid>
    <DataGrid.Columns>
        <DataGridTemplateColumn>
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
            <DataGridTemplateColumn.CellEditingTemplate>
                <DataTemplate>
                    <TextBox Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellEditingTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

Since the TextBlock and the TextBox specified in the cell templates will be part of the visual tree, you can walk up and find whatever control you need.

You can retrieve the height of the IFRAME's content by using: contentWindow.document.body.scrollHeight

After the IFRAME is loaded, you can then change the height by doing the following:

<script type="text/javascript">
  function iframeLoaded() {
      var iFrameID = document.getElementById('idIframe');
      if(iFrameID) {
            // here you can make the height, I delete it first, then I make it again
            iFrameID.height = "";
            iFrameID.height = iFrameID.contentWindow.document.body.scrollHeight + "px";
      }   
  }
</script>   

Then, on the IFRAME tag, you hook up the handler like this:

<iframe id="idIframe" onload="iframeLoaded()" ...

I had a situation a while ago where I additionally needed to call iframeLoaded from the IFRAME itself after a form-submission occurred within. You can accomplish that by doing the following within the IFRAME's content scripts:

parent.iframeLoaded();

I using "+" (plus) to insert div to html :

document.getElementById('idParent').innerHTML += '<div id="idChild"> content html </div>';

Hope this help.

Problem

The trim() method removes whitespace from both sides of a string.

Source

Solution

You can use a Javascript replace method to remove white space like

"hello world".replace(/\s/g, "");

Example

var out = "hello world".replace(/\s/g, "");_x000D_
console.log(out);

If you like entering arcane operators from the command line, you’ll love these manual container backup techniques. Keep in mind, there’s a faster and more efficient way to backup containers that’s just as effective. I've written instructions here: https://www.morpheusdata.com/blog/2017-03-02-how-to-create-a-docker-backup-with-morpheus

Step 1: Add a Docker Host to Any Cloud As explained in a tutorial on the Morpheus support site, you can add a Docker host to the cloud of your choice in a matter of seconds. Start by choosing Infrastructure on the main Morpheus navigation bar. Select Hosts at the top of the Infrastructure window, and click the “+Container Hosts” button at the top right.

To back up a Docker host to a cloud via Morpheus, navigate to the Infrastructure screen and open the “+Container Hosts” menu.

Choose a container host type on the menu, select a group, and then enter data in the five fields: Name, Description, Visibility, Select a Cloud and Enter Tags (optional). Click Next, and then configure the host options by choosing a service plan. Note that the Volume, Memory, and CPU count fields will be visible only if the plan you select has custom options enabled.

Here is where you add and size volumes, set memory size and CPU count, and choose a network. You can also configure the OS username and password, the domain name, and the hostname, which by default is the container name you entered previously. Click Next, and then add any Automation Workflows (optional).Finally, review your settings and click Complete to save them.

Step 2: Add Docker Registry Integration to Public or Private Clouds Adam Hicks describes in another Morpheus tutorial how simple it is to integrate with a private Docker Registry. (No added configuration is required to use Morpheus to provision images with Docker’s public hub using the public Docker API.)

Select Integrations under the Admin tab of the main navigation bar, and then choose the “+New Integration” button on the right side of the screen. In the Integration window that appears, select Docker Repository in the Type drop-down menu, enter a name and add the private registry API endpoint. Supply a username and password for the registry you’re using, and click the Save Changes button.

Integrate a Docker Registry with a private cloud via the Morpheus “New Integration” dialog box.

To provision the integration you just created, choose Docker under Type in the Create Instance dialog, select the registry in the Docker Registry drop-down menu under the Configure tab, and then continue provisioning as you would any Docker container.

Step 3: Manage Backups Once you’ve added the Docker host and integrated the registry, a backup will be configured and performed automatically for each instance you provision. Morpheus support provides instructions for viewing backups, creating an instance backup, and creating a server backup.

I tend to find that if I'm specifying individual colours in multiple geom's, I'm doing it wrong. Here's how I would plot your data:

##Subset the necessary columns
dd_sub = datos[,c(20, 2,3,5)]
##Then rearrange your data frame
library(reshape2)
dd = melt(dd_sub, id=c("fecha"))

All that's left is a simple ggplot command:

ggplot(dd) + geom_line(aes(x=fecha, y=value, colour=variable)) +
  scale_colour_manual(values=c("red","green","blue"))

Example plot

The images c, d, e , and f in the following show colorspace conversion they also happen to be numpy arrays <type 'numpy.ndarray'>:

import numpy, cv2
def show_pic(p):
        ''' use esc to see the results'''
        print(type(p))
        cv2.imshow('Color image', p)
        while True:
            k = cv2.waitKey(0) & 0xFF
            if k == 27: break 
        return
        cv2.destroyAllWindows()

b = numpy.zeros([200,200,3])

b[:,:,0] = numpy.ones([200,200])*255
b[:,:,1] = numpy.ones([200,200])*255
b[:,:,2] = numpy.ones([200,200])*0
cv2.imwrite('color_img.jpg', b)


c = cv2.imread('color_img.jpg', 1)
c = cv2.cvtColor(c, cv2.COLOR_BGR2RGB)

d = cv2.imread('color_img.jpg', 1)
d = cv2.cvtColor(c, cv2.COLOR_RGB2BGR)

e = cv2.imread('color_img.jpg', -1)
e = cv2.cvtColor(c, cv2.COLOR_BGR2RGB)

f = cv2.imread('color_img.jpg', -1)
f = cv2.cvtColor(c, cv2.COLOR_RGB2BGR)


pictures = [d, c, f, e]

for p in pictures:
        show_pic(p)
# show the matrix
print(c)
print(c.shape)

See here for more info: http://docs.opencv.org/modules/imgproc/doc/miscellaneous_transformations.html#cvtcolor

OR you could:

img = numpy.zeros([200,200,3])

img[:,:,0] = numpy.ones([200,200])*255
img[:,:,1] = numpy.ones([200,200])*255
img[:,:,2] = numpy.ones([200,200])*0

r,g,b = cv2.split(img)
img_bgr = cv2.merge([b,g,r])

Use System.Security.Principal.WindowsIdentity.GetCurrent().Name.

This will get the current logged-in Windows user.

There's no (safe) way to pause execution. You can, however, do something like this using setTimeout:

function writeNext(i)
{
    document.write(i);

    if(i == 5)
        return;

    setTimeout(function()
    {
        writeNext(i + 1);

    }, 2000);
}

writeNext(1);

Use the HAVING, not WHERE clause, for aggregate result comparison.

Taking the query at face value:

SELECT * 
  FROM db.table 
HAVING COUNT(someField) > 1

Ideally, there should be a GROUP BY defined for proper valuation in the HAVING clause, but MySQL does allow hidden columns from the GROUP BY...

Is this in preparation for a unique constraint on someField? Looks like it should be...

Here's another answer for the ASP.Net Core solution to this problem...

On the Angular side, I took this code example...

https://stackblitz.com/edit/angular-drag-n-drop-directive

... and modified it to call an HTTP Post endpoint:

  prepareFilesList(files: Array<any>) {

    const formData = new FormData();
    for (var i = 0; i < files.length; i++) { 
      formData.append("file[]", files[i]);
    }

    let URL = "https://localhost:44353/api/Users";
    this.http.post(URL, formData).subscribe(
      data => { console.log(data); },
      error => { console.log(error); }
    );

With this in place, here's the code I needed in the ASP.Net Core WebAPI controller:

[HttpPost]
public ActionResult Post()
{
  try
  {
    var files = Request.Form.Files;

    foreach (IFormFile file in files)
    {
        if (file.Length == 0)
            continue;
        
        string tempFilename = Path.Combine(Path.GetTempPath(), file.FileName);
        System.Diagnostics.Trace.WriteLine($"Saved file to: {tempFilename}");

        using (var fileStream = new FileStream(tempFilename, FileMode.Create))
        {
            file.CopyTo(fileStream);
        }
    }
    return new OkObjectResult("Yes");
  }
  catch (Exception ex)
  {
    return new BadRequestObjectResult(ex.Message);
  }
}

Shockingly simple, but I had to piece together examples from several (almost-correct) sources to get this to work properly.

Since API Level 21 (Lollipop) Android provides a PdfRenderer class:

// create a new renderer
 PdfRenderer renderer = new PdfRenderer(getSeekableFileDescriptor());

 // let us just render all pages
 final int pageCount = renderer.getPageCount();
 for (int i = 0; i < pageCount; i++) {
     Page page = renderer.openPage(i);

     // say we render for showing on the screen
     page.render(mBitmap, null, null, Page.RENDER_MODE_FOR_DISPLAY);

     // do stuff with the bitmap

     // close the page
     page.close();

For older APIs I recommend Android PdfViewer library, it is very fast and easy to use, licensed under Apache License 2.0:

pdfView.fromAsset(String)
  .pages(0, 2, 1, 3, 3, 3) // all pages are displayed by default
  .enableSwipe(true)
  .swipeHorizontal(false)
  .enableDoubletap(true)
  .defaultPage(0)
  .onDraw(onDrawListener)
  .onLoad(onLoadCompleteListener)
  .onPageChange(onPageChangeListener)
  .onPageScroll(onPageScrollListener)
  .onError(onErrorListener)
  .enableAnnotationRendering(false)
  .password(null)
  .scrollHandle(null)
  .load();

You have a pointer to an object. Therefore, you need to access a field of an object that's pointed to by the pointer. To dereference the pointer you use *, and to access a field, you use ., so you can use:

cout << (*kwadrat).val1;

Note that the parentheses are necessary. This operation is common enough that long ago (when C was young) they decided to create a "shorthand" method of doing it:

cout << kwadrat->val1;

These are defined to be identical. As you can see, the -> basically just combines a * and a . into a single operation. If you were dealing directly with an object or a reference to an object, you'd be able to use the . without dereferencing a pointer first:

Kwadrat kwadrat2(2,3,4);

cout << kwadrat2.val1;

The :: is the scope resolution operator. It is used when you only need to qualify the name, but you're not dealing with an individual object at all. This would be primarily to access a static data member:

struct something { 
    static int x; // this only declares `something::x`. Often found in a header
};

int something::x;  // this defines `something::x`. Usually in .cpp/.cc/.C file.

In this case, since x is static, it's not associated with any particular instance of something. In fact, it will exist even if no instance of that type of object has been created. In this case, we can access it with the scope resolution operator:

something::x = 10;

std::cout << something::x;

Note, however, that it's also permitted to access a static member as if it was a member of a particular object:

something s;

s.x = 1;

At least if memory serves, early in the history of C++ this wasn't allowed, but the meaning is unambiguous, so they decided to allow it.

You don't need to make any loops and collect/reprocess data. The json object you need is here:

var jsonData = store.proxy.reader.jsonData;

We basically use user controls when we have to use similar functionality on different locations of an app. Like we use master pages for consistent look and feel of app, similarly to avoid repeating the same functionality and UI all over the app, we use usercontrols. There might me much more usage too, but I know this one only...

For example, let's say your site has 4 levels of users and for each user there are different pages under different directories with different access mechanisms. Say you are requesting address info for all users, then creating address fields like Street, City, State, Zip, etc on each page. That would be a repetitive job. Instead you can create it as an ascx file (ext for user control) and in this control put the necessary UI and business code for add/update/delete/select the address role wise and then simply reference it all required page.

So, thought user controls, one can avoid code repetition for each role and UI creation for each role.

For those looking for a way to do this with $object->method:

call_user_func_array(array($object, 'method_name'), $array);

I was successful with this in a construct function that calls a variable method_name with variable parameters.

Consider the following code:

error_reporting(E_STRICT);
class test {
    function test_arr(&$a) {
        var_dump($a);
    }
    function get_arr() {
        return array(1, 2);
    }
}

$t = new test;
$t->test_arr($t->get_arr());

This will generate the following output:

Strict Standards: Only variables should be passed by reference in `test.php` on line 14
array(2) {
  [0]=>
  int(1)
  [1]=>
  int(2)
}

The reason? The test::get_arr() method is not a variable and under strict mode this will generate a warning. This behavior is extremely non-intuitive as the get_arr() method returns an array value.

To get around this error in strict mode, either change the signature of the method so it doesn't use a reference:

function test_arr($a) {
    var_dump($a);
}

Since you can't change the signature of array_shift you can also use an intermediate variable:

$inter = get_arr();
$el = array_shift($inter);

You can do this:

$('.searchbychar').click(function () {
    var divID = '#' + this.id;
    $('html, body').animate({
        scrollTop: $(divID).offset().top
    }, 2000);
});

F.Y.I.

• You need to prefix a class name with a . (dot) like in your first line of code.
• $( 'searchbychar' ).click(function() {
• Also, your code $('.searchbychar').attr('id') will return a string ID not a jQuery object. Hence, you can not apply .offset() method to it.

Given a data URL, you can create an image (either on the page or purely in JS) by setting the src of the image to your data URL. For example:

var img = new Image;
img.src = strDataURI;

The drawImage() method of HTML5 Canvas Context lets you copy all or a portion of an image (or canvas, or video) onto a canvas.

You might use it like so:

var myCanvas = document.getElementById('my_canvas_id');
var ctx = myCanvas.getContext('2d');
var img = new Image;
img.onload = function(){
  ctx.drawImage(img,0,0); // Or at whatever offset you like
};
img.src = strDataURI;

Edit: I previously suggested in this space that it might not be necessary to use the onload handler when a data URI is involved. Based on experimental tests from this question, it is not safe to do so. The above sequence—create the image, set the onload to use the new image, and then set the src—is necessary for some browsers to surely use the results.

You can see the following code to solved the problem

return $query->join('kg_shops', function($join)
{
    $join->on('kg_shops.id', '=', 'kg_feeds.shop_id');
    $join->where('kg_shops.active','=', 1);
});

Or another way to solved it

 return $query->join('kg_shops', function($join)
{
    $join->on('kg_shops.id', '=', 'kg_feeds.shop_id');
    $join->on('kg_shops.active','=', DB::raw('1'));
});

This is my solution to scroll to the top on a button click.

$(".btn").click(function () {
if ($(this).text() == "Show options") {
$(".tabs").animate(
  {
    scrollTop: $(window).scrollTop(0)
  },
  "slow"
 );
 }
});

The proper way is mvn package if you did things correctly for the core part of your build then there should be no need to install your packages in the local repository.

In addition if you use Travis you can "cache" your dependencies because it will not touch your $HOME.m2/repository if you use package for your own project.

In practicality if you even attempt to do a mvn site you usually need to do a mvn install before. There's just too many bugs with either site or it's numerous poorly maintained plugins.

If you do not specifically need the alt text of an image, then you can just target the class/id of the image.

$('img.propImg').each(function(){ 
     enter code here
}

I know it’s not quite answering the question, though I’d spent ages trying to figure this out and this question gave me the solution :). In my case I needed to hide any image tags with a specific src.

$('img.propImg').each(function(){ //for each loop that gets all the images. 
        if($(this).attr('src') == "img/{{images}}") { // if the src matches this
        $(this).css("display", "none") // hide the image.
    }
});

The SyntheticEvent interface is generic:

interface SyntheticEvent<T> {
    ...
    currentTarget: EventTarget & T;
    ...
}

(Technically the currentTarget property is on the parent BaseSyntheticEvent type.)

And the currentTarget is an intersection of the generic constraint and EventTarget.
Also, since your events are caused by an input element you should use the ChangeEvent (in definition file, the react docs).

Should be:

update = (e: React.ChangeEvent<HTMLInputElement>): void => {
    this.props.login[e.currentTarget.name] = e.currentTarget.value
}

(Note: This answer originally suggested using React.FormEvent. The discussion in the comments is related to this suggestion, but React.ChangeEvent should be used as shown above.)

Have you seen the the bootstrap's afix in the JAvascript's section ???

I think it would be the best & easiest solution dude.

Here is Html code:-

    <body>
    <div ng-controller="MyController" class="container">
      <h1>Modal example</h1>
      <button ng-click="open()" class="btn btn-primary">Test Modal</button>

      <modal title="Login form" visible="showModal">
        <form role="form">

        </form>
      </modal>
    </div>
</body>

AngularJs code:-

var mymodal = angular.module('mymodal', []);

mymodal.controller('MyController', function ($scope) {
    $scope.showModal = false;
    $scope.open = function(){
    $scope.showModal = !$scope.showModal;
    };
  });

mymodal.directive('modal', function () {
    return {
      template: '<div class="modal fade">' + 
          '<div class="modal-dialog">' + 
            '<div class="modal-content">' +

I saw the same error and solved by switching off the proxy settings in TortoiseSVN that I normally need for commits to the company servers. I installed Subclipse to back up my own non-prime-time stuff to a local repository (using VisualSVN). I use Eclipse Galileo 3.3 and Subclipse 1.6.12.

In Visual Studio:

Tools -> Nuget Package Manager -> Package Manager Console.

In PM:

Install-Package NuGet.CommandLine

Close Visual Studio and open it again.

This solution worked to me:

<summary>Tootsie roll tiramisu macaroon wafer carrot cake. &#xD;Danish topping sugar plum tart bonbon caramels cake.</summary>

You will have the text in two lines.

This worked to me using the XmlReader.Read method.

This method worked for me:

RelativeLayout relativeLayout = (RelativeLayout) findViewById(R.layout.rootLayout);
relativeLayout.setBackgroundColor(getResources().getColor(R.color.bg_color_2));

Set id in layout xml

xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/rootLayout"
android:background="@color/background_color"

Add color values/color.xml

<color name="bg_color_2">#ffeef7f0</color>

To switch between different images when the ImageButton is clicked I used a boolean like this:

ImageButton imageButton;
boolean buttonOn;

imageButton.setOnClickListener(new View.OnClickListener() {
     @Override
     public void onClick(View v) {
         if (!buttonOn) {
             buttonOn = true;
             imageButton.setBackground(getResources().getDrawable(R.drawable.button_is_on)); 
         } else {
             buttonOn = false;
             imageButton.setBackground(getResources().getDrawable(R.drawable.button_is_off));
         }
     }
});

Step 1 - Rename the project

1. Click on the project you want to rename in the "Project navigator" in the left panel of the Xcode window.
2. In the right panel, select the "File inspector", and the name of your project should be found under "Identity and Type". Change it to your new name.
3. When the dialog asks whether to rename or not rename the project's content items, click "Rename". Say yes to any warning about uncommitted changes.

Step 2 - Rename the scheme

1. At the top of the window, next to the "Stop" button, there is a scheme for your product under its old name; click on it, then choose "Manage Schemes…".
2. Click on the old name in the scheme and it will become editable; change the name and click "Close".

Step 3 - Rename the folder with your assets

1. Quit Xcode. Rename the master folder that contains all your project files.
2. In the correctly-named master folder, beside your newly-named .xcodeproj file, there is probably a wrongly-named OLD folder containing your source files. Rename the OLD folder to your new name (if you use Git, you could run git mv oldname newname so that Git recognizes this is a move, rather than deleting/adding new files).
3. Re-open the project in Xcode. If you see a warning "The folder OLD does not exist", dismiss the warning. The source files in the renamed folder will be grayed out because the path has broken.
4. In the "Project navigator" in the left-hand panel, click on the top-level folder representing the OLD folder you renamed.
5. In the right-hand panel, under "Identity and Type", change the "Name" field from the OLD name to the new name.
6. Just below that field is a "Location" menu. If the full path has not corrected itself, click on the nearby folder icon and choose the renamed folder.

Step 4 - Rename the Build plist data

1. Click on the project in the "Project navigator" on the left, and in the main panel select "Build Settings".
2. Search for "plist" in the settings.
3. In the Packaging section, you will see Info.plist and Product Bundle Identifier.
4. If there is a name entered in Info.plist, update it.
5. Do the same for Product Bundle Identifier, unless it is utilizing the ${PRODUCT_NAME} variable. In that case, search for "product" in the settings and update Product Name. If Product Name is based on ${TARGET_NAME}, click on the actual target item in the TARGETS list on the left of the settings pane and edit it, and all related settings will update immediately.
6. Search the settings for "prefix" and ensure that Prefix Header's path is also updated to the new name.
7. If you use SwiftUI, search for "Development Assets" and update the path.

Step 5 - Repeat step 3 for tests (if you have them)

Step 6 - Repeat step 3 for core data if its name matches project name (if you have it)

Step 7 - Clean and rebuild your project

1. Command + Shift + K to clean
2. Command + B to build

$where = "name='Joe' AND status='boss' OR status='active'";

$this->db->where($where);

If you're simply sharing a counter, consider using an AtomicInteger or another suitable class from the java.util.concurrent.atomic package:

public class Test {

    private final static AtomicInteger count = new AtomicInteger(0); 

    public void foo() {  
        count.incrementAndGet();
    }  
}

cJSON has a decent API and is small (2 files, ~700 lines). Many of the other JSON parsers I looked at first were huge... I just want to parse some JSON.

Edit: We've made some improvements to cJSON over the years.

additionally you can just write

if(stop)
{
        sb.append("y");
        getWhoozitYs();
}

It largely depends on the library you decide to use. For instance, if you use the wxWidgets library, the creation of a thread would look like this:

class RThread : public wxThread {

public:
    RThread()
        : wxThread(wxTHREAD_JOINABLE){
    }
private:
    RThread(const RThread &copy);

public:
    void *Entry(void){
        //Do...

        return 0;
    }

};

wxThread *CreateThread() {
    //Create thread
    wxThread *_hThread = new RThread();

    //Start thread
    _hThread->Create();
    _hThread->Run();

    return _hThread;
}

If your main thread calls the CreateThread method, you'll create a new thread that will start executing the code in your "Entry" method. You'll have to keep a reference to the thread in most cases to join or stop it. More info here: wxThread documentation

For OSX: pip install scikit-image

and then run python to try following

from skimage.feature import corner_harris, corner_peaks

In layman terms we can say that Persistence Context is an environment where entities are managed, i.e it syncs "Entity" with the database.

You can mimic the Ping command.

Use Ajax to request a timestamp to your own server, define a timer using setTimeout to 5 seconds, if theres no response it try again.

If there's no response in 4 attempts, you can suppose that internet is down.

So you can check using this routine in regular intervals like 1 or 3 minutes.

That seems a good and clean solution for me.

If a <script> has a src then the text content of the element will be not be executed as JS (although it will appear in the DOM).

You need to use multiple script elements.

1. a <script> to load the external script

2. a <script> to hold your inline code (with the call to the function in the external script)

   scroll_messages();

If your Windows 7 machine is a member of an AD, or if you have UAC enabled, or if security policies are in effect, telnet more often than not must be run as an admin. The easiest way to do this is as follows

1. Create a shortcut that calls cmd.exe

2. Go to the shortcut's properties

3. Click on the Advanced button

4. Check the "Run as an administrator" checkbox

   After these steps you're all set and telnet should work now.

By default, Windows makes the root of each drive available (provided you've got Administrator privileges) as (e.g.) \\server\c$. These are known as Administrative Shares.

Before User Shift + = or Shift - , you have to first set the key map as mentioned below

Use:

(summary(fit))$coefficients[***num***,4]

where num is a number which denotes the row of the coefficients matrix. It will depend on how many features you have in your model and which one you want to pull out the p-value for. For example, if you have only one variable there will be one p-value for the intercept which will be [1,4] and the next one for your actual variable which will be [2,4]. So your num will be 2.

Of course you can, in the sense that your RDBMS will let you do it. The answer to a question of whether or not you should do it is different, though: in most situations, values that have a meaning outside your database system should not be chosen to be a primary key.

If you know that the value is unique in the system that you are modeling, it is appropriate to add a unique index or a unique constraint to your table. However, your primary key should generally be some "meaningless" value, such as an auto-incremented number or a GUID.

The rationale for this is simple: data entry errors and infrequent changes to things that appear non-changeable do happen. They become much harder to fix on values which are used as primary keys.

Pretty easy way for rather short lists:

1. Double click on the box where the url is
2. Enter

Use the return keyword to exit from a method.

public void someMethod() {
    //... a bunch of code ...
    if (someCondition()) {
        return;
    }
    //... otherwise do the following...
}

From the Java Tutorial that I linked to above:

Any method declared void doesn't return a value. It does not need to contain a return statement, but it may do so. In such a case, a return statement can be used to branch out of a control flow block and exit the method and is simply used like this:

return;

This restriction makes sure all files or modules (exports) are inside src/ directory, the implementation is in ./node_modules/react-dev-utils/ModuleScopePlugin.js, in following lines of code.

// Resolve the issuer from our appSrc and make sure it's one of our files
// Maybe an indexOf === 0 would be better?
     const relative = path.relative(appSrc, request.context.issuer);
// If it's not in src/ or a subdirectory, not our request!
     if (relative.startsWith('../') || relative.startsWith('..\\')) {
        return callback();
      }

You can remove this restriction by

1. either changing this piece of code (not recommended)
2. or do eject then remove ModuleScopePlugin.js from the directory.
3. or comment/remove const ModuleScopePlugin = require('react-dev-utils/ModuleScopePlugin'); from ./node_modules/react-scripts/config/webpack.config.dev.js

PS: beware of the consequences of eject.

You can also try to use get(), for example:

connection = manager.connect.get("I2Cx")

which won't raise a KeyError in case the key doesn't exist.

You may also use second argument to specify the default value, if the key is not present.

No, you can simply use com.fasterxml.jackson.databind.ObjectMapper. Most likely you forgot to fix your import-statements, delete all references to codehaus and you're golden.

The generic way to ignore all subfolders, while continuing to track the files that are in the /bin directory would be to add the following line to your project's .gitignore file:

bin/*/*

If you want to ignore only particular named subfolders, you can do:

bin/Debug/*
bin/Release/*

nb. if the bin directory is not in the root of your project (alongside the .gitignore file), then instead of eg. bin/*/* you might need path/to/bin/*/*

Rendering engine goes several steps till it paints anything on the screen.

it looks like this:

1. Converting HTML bytes to characters depending on encoding we set to the document;
2. Tokens are created according to characters. Tokens mean analyze characters and specify opening tangs and nested tags;
3. From tokens separated nodes are created. they are objects and according to information delivered from tokenization process, engine creates objects which includes all necessary information about each node;
4. after that DOM is created. DOM is tree data structure and represents whole hierarchy and information about relationship and specification of tags;

The same process goes to CSS. for CSS rendering engine creates different/separated data structure for CSS but it's called CSSOM (CSS Object Model)

Browser works only with Object models so it needs to know all information about DOM and CSSDOM.

The next step is combining somehow DOM and CSSOM. because without CSSOM browser do not know how to style each element during rendering process.

All information above means that, anything you provide in your html (javascript, css ) browser will pause DOM construction process. If you are familiar with event loop, there is simple rule how event loop executes tasks:

1. Execute macro tasks;
2. execute micro tasks;
3. Rendering;

So when you provide Javascript file, browser do not know what JS code is going to do and stops all DOM construction process and Javascript interptreter starts parsing and executing Javascript code.

Even you provide Javascript in the end of body tag, Browser will proceed all above steps to HTML and CSS but except rendering. it will find out Script tag and will stop until JS is done.

But HTML provided two additional options for script tag: async and defer.

Async - means execute code when it is downloaded and do not block DOM construction during downloading process.

Defer - means execute code after it's downloaded and browser finished DOM construction and rendering process.

I just encountered this in my code and it took me a while to figure it out. I was doing an intersection of two sorted lists and was only getting small numbers in my output. I could get it to work by using (x - y == 0) instead of (x == y) during comparison.

df.set_index('Date', inplace=True)
df['adj_close'].plot()

If you want a chart with one series by ticker on it

You need to groupby before:

df.set_index('Date', inplace=True)
df.groupby('ticker')['adj_close'].plot(legend=True)

If you want a chart with individual subplots:

grouped = df.groupby('ticker')

ncols=2
nrows = int(np.ceil(grouped.ngroups/ncols))

fig, axes = plt.subplots(nrows=nrows, ncols=ncols, figsize=(12,4), sharey=True)

for (key, ax) in zip(grouped.groups.keys(), axes.flatten()):
    grouped.get_group(key).plot(ax=ax)

ax.legend()
plt.show()

In C++, the size of int isn't specified explicitly. It just tells you that it must be at least the size of short int, which must be at least as large as signed char. The size of char in bits isn't specified explicitly either, although sizeof(char) is defined to be 1. If you want a 64 bit int, C++11 specifies long long to be at least 64 bits.

A lot of people, including me, use sqlfiddle.com to test SQL.

Try this if you want to display one of duplicate rows based on RequestID and CreatedDate and show the latest HistoryStatus.

with t as (select row_number()over(partition by RequestID,CreatedDate order by RequestID) as rnum,* from tbltmp)
Select RequestID,CreatedDate,HistoryStatus from t a where  rnum in (SELECT Max(rnum) FROM t GROUP BY RequestID,CreatedDate having t.RequestID=a.RequestID)

or if you want to select one of duplicate rows considering CreatedDate only and show the latest HistoryStatus then try the query below.

with t as (select row_number()over(partition by CreatedDate order by RequestID) as rnum,* from tbltmp)
Select RequestID,CreatedDate,HistoryStatus from t  where  rnum = (SELECT Max(rnum) FROM t)

Or if you want to select one of duplicate rows considering Request ID only and show the latest HistoryStatus then use the query below

with t as (select row_number()over(partition by RequestID order by RequestID) as rnum,* from tbltmp)
Select RequestID,CreatedDate,HistoryStatus from t a where  rnum in (SELECT Max(rnum) FROM t GROUP BY RequestID,CreatedDate having t.RequestID=a.RequestID)

All the above queries I have written in sql server 2005.

Here's an alternative:

<svg ...>
  <switch>
    <g requiredFeatures="http://www.w3.org/Graphics/SVG/feature/1.2/#TextFlow">
      <textArea width="200" height="auto">
       Text goes here
      </textArea>
    </g>
    <foreignObject width="200" height="200" 
     requiredFeatures="http://www.w3.org/TR/SVG11/feature#Extensibility">
      <p xmlns="http://www.w3.org/1999/xhtml">Text goes here</p>
    </foreignObject>
    <text x="20" y="20">No automatic linewrapping.</text>
  </switch>
</svg>

Noting that even though foreignObject may be reported as being supported with that featurestring, there's no guarantee that HTML can be displayed because that's not required by the SVG 1.1 specification. There is no featurestring for html-in-foreignobject support at the moment. However, it is still supported in many browsers, so it's likely to become required in the future, perhaps with a corresponding featurestring.

Note that the 'textArea' element in SVG Tiny 1.2 supports all the standard svg features, e.g advanced filling etc, and that you can specify either of width or height as auto, meaning that the text can flow freely in that direction. ForeignObject acts as clipping viewport.

Note: while the above example is valid SVG 1.1 content, in SVG 2 the 'requiredFeatures' attribute has been removed, which means the 'switch' element will try to render the first 'g' element regardless of having support for SVG 1.2 'textArea' elements. See SVG2 switch element spec.

You can use as below and also can use various color just assign

myLabel.textColor = UIColor.yourChoiceOfColor

Ex:

Swift

myLabel.textColor = UIColor.red

Objective-C

[myLabel setTextColor:[UIColor redColor]];

or you can click here to Choose the color,

You just need to create a class which extends Exception (for a checked exception) or any subclass of Exception, or RuntimeException (for a runtime exception) or any subclass of RuntimeException.

Then, in your code, just use

if (word.contains(" "))
    throw new MyException("some message");
}

Read the Java tutorial. This is basic stuff that every Java developer should know: http://docs.oracle.com/javase/tutorial/essential/exceptions/

The problem is not one of technical ability to send through gmail. That works for most situations. If you can't get a machine to send, it is usually due to the machine not having been authenticated with a human at the controls at least once.

The problem that most users face is that Google decides to change the outbound limits all the time. You should always add defensive code to your solution. If you start seeing errors, step off your send speed and just stop sending for a while. If you keep trying to send Google will sometimes add extra time to your delay period before you can send again.

What I have done in my current system is to send with a 1.5 second delay between each message. Then if I get any errors, stop for 5 minutes and then start again. This usually works and will allow you to send up to the limits of the account (last I checked it was 2,000 for premier customer logins per day).

The override keyword serves two purposes:

1. It shows the reader of the code that "this is a virtual method, that is overriding a virtual method of the base class."
2. The compiler also knows that it's an override, so it can "check" that you are not altering/adding new methods that you think are overrides.

To explain the latter:

class base
{
  public:
    virtual int foo(float x) = 0; 
};


class derived: public base
{
   public:
     int foo(float x) override { ... } // OK
}

class derived2: public base
{
   public:
     int foo(int x) override { ... } // ERROR
};

In derived2 the compiler will issue an error for "changing the type". Without override, at most the compiler would give a warning for "you are hiding virtual method by same name".

• Broadcast: We can pass the value from parent to child (i.e parent -> child controller.)
• Emit: we can pass the value from child to parent (i.e.child ->parent controller.)
• On: catch the event dispatched by $broadcast or $emit.

A standard way to achieve this would be to use the pkg_resources module which is part of the setuptools package. setuptools is used to create an install-able python package.

You can use pkg_resources to return the contents of your desired file as a string and you can use pkg_resources to get the actual path of the desired file on your system.

Let's say that you have a package called stackoverflow.

stackoverflow/
|-- app
|   `-- __init__.py
`-- resources
    |-- bands
    |   |-- Dream\ Theater
    |   |-- __init__.py
    |   |-- King's\ X
    |   |-- Megadeth
    |   `-- Rush
    `-- __init__.py

3 directories, 7 files

Now let's say that you want to access the file Rush from a module app.run. Use pkg_resources.resouces_filename to get the path to Rush and pkg_resources.resource_string to get the contents of Rush; thusly:

import pkg_resources

if __name__ == "__main__":
    print pkg_resources.resource_filename('resources.bands', 'Rush')
    print pkg_resources.resource_string('resources.bands', 'Rush')

The output:

/home/sri/workspace/stackoverflow/resources/bands/Rush
Base: Geddy Lee
Vocals: Geddy Lee
Guitar: Alex Lifeson
Drums: Neil Peart

This works for all packages in your python path. So if you want to know where lxml.etree exists on your system:

import pkg_resources

if __name__ == "__main__":
    print pkg_resources.resource_filename('lxml', 'etree')

output:

/usr/lib64/python2.7/site-packages/lxml/etree

The point is that you can use this standard method to access files that are installed on your system (e.g pip install xxx or yum -y install python-xxx) and files that are within the module that you're currently working on.

I do not like use pure "a" tag, too much typing. So I come with solution. In view it look

<%: Html.ActionLink(node.Name, "Show", "Browse", 
                    Dic.Route("id", node.Id), Dic.New("data-nodeId", node.Id)) %>

Implementation of Dic class

public static class Dic
{
    public static Dictionary<string, object> New(params object[] attrs)
    {
        var res = new Dictionary<string, object>();
        for (var i = 0; i < attrs.Length; i = i + 2)
            res.Add(attrs[i].ToString(), attrs[i + 1]);
        return res;
    }

    public static RouteValueDictionary Route(params object[] attrs)
    {
        return new RouteValueDictionary(Dic.New(attrs));
    }
}

String loudScreaming = json.getJSONObject("LabelData").getString("slogan");

The [:-1] removes the last element. Instead of

a[3:-1]

write

a[3:]

You can read up on Python slicing notation here: Explain Python's slice notation

NumPy slicing is an extension of that. The NumPy tutorial has some coverage: Indexing, Slicing and Iterating.

From your description, what you probably want is os.Readdirnames.

func (f *File) Readdirnames(n int) (names []string, err error)

Readdirnames reads the contents of the directory associated with file and returns a slice of up to n names of files in the directory, in directory order. Subsequent calls on the same file will yield further names.

...

If n <= 0, Readdirnames returns all the names from the directory in a single slice.

Snippet:

file, err := os.Open(path)
if err != nil {
    return err
}
defer file.Close()
names, err := file.Readdirnames(0)
if err != nil {
    return err
}
fmt.Println(names)

Credit to SquattingSlavInTracksuit's comment; I'd have suggested promoting their comment to an answer if I could.

Nearly verbatim from Iterate over pairs in a list (circular fashion) in Python:

def pairs(seq):
    i = iter(seq)
    prev = next(i)
    for item in i:
        yield prev, item
        prev = item

It seems that the compiler is better in optimizing a switch-statement than an if-statement.

The compiler doesn't know if the order of evaluating the if-statements is important to you, and can't perform any optimizations there. You could be calling methods in the if-statements, influencing variables. With the switch-statement it knows that all clauses can be evaluated at the same time and can put them in whatever order is most efficient.

Here's a small comparison:
http://www.blackwasp.co.uk/SpeedTestIfElseSwitch.aspx

I agree with Jim Blizard. The database is not the part of your technology stack that should send emails. For example, what if you send an email but then roll back the change that triggered that email? You can't take the email back.

It's better to send the email in your application code layer, after your app has confirmed that the SQL change was made successfully and committed.

You need the Microsoft.AspNet.WebApi.Core package.

You can see it in the .csproj file:

Answer

• Create a Template
• Set the Template's innerHTML to your string .trim()
• Create an Array of Template's children
• Return children, child, or

function toElement(s='',c,t=document.createElement('template'),l='length'){
t.innerHTML=s.trim();c=[...t.content.childNodes];return c[l]>1?c:c[0]||'';}



console.log(toElement());
console.log(toElement(''));
console.log(toElement('    '));
console.log(toElement('<td>With td</td>'));
console.log(toElement('<tr><td>With t</td></tr>'));
console.log(toElement('<tr><td>foo</td></tr><tr><td>bar</td></tr>'));
console.log(toElement('<div><span>nested</span> <span>stuff</span></div>'));

You can see formControlName in label , removing this solved my problem

You can use the method split:

public class Demo {
    public static void main(String args[]) {
        String str = "004-034556";

        if ((str.contains("-"))) {
            String[] temp = str.split("-");
            for (String part:temp) {
                System.out.println(part);
            }
        }
        else {
            System.out.println(str + " does not contain \"-\".");
        }
    }
}

Try CTRL+P,CTRL+Q to turn interactive mode to daemon.

If this does not work and you attached through docker attach, you can detach by killing the docker attach process.

Better way is to use sig-proxy parameter to avoid passing the CTRL+C to your container :

docker attach --sig-proxy=false [container-name]

Same option is available for docker run command.

You are running into a scope problem if you use your code as such. You have to declare it outside the functions if you plan to use it between them (or if calling, pass it as a parameter).

var a = new Array();
var b = new Object();

function first() {
a.push(b);
// Alternatively, a[a.length] = b
// both methods work fine
}

function second() {
var c = a[0];
}

// code
first();
// more code
second();
// even more code

public function showstudents() {
     $students = DB::table('student')->get();
     return (View::make("user/regprofile", compact('student')));
}

var datatable_jquery_script = document.createElement("script");
datatable_jquery_script.src = "vendor/datatables/jquery.dataTables.min.js";
document.body.appendChild(datatable_jquery_script);
setTimeout(function(){
    var datatable_bootstrap_script = document.createElement("script");
    datatable_bootstrap_script.src = "vendor/datatables/dataTables.bootstrap4.min.js";
    document.body.appendChild(datatable_bootstrap_script);
},100);

I used setTimeOut to make sure datatables.min.js loads first. I inspected the waterfall loading of each, bootstrap4.min.js always loads first.

You create buttons dynamically because of that you need to call them with .live() method if you use jquery 1.7

but this method is deprecated (you can see the list of all deprecated method here) in newer version. if you want to use jquery 1.10 or above you need to call your buttons in this way:

$(document).on('click', 'selector', function(){ 
     // Your Code
});

For Example

If your html is something like this

<div id="btn-list">
    <div class="btn12">MyButton</div>
</div>

You can write your jquery like this

$(document).on('click', '#btn-list .btn12', function(){ 
     // Your Code
});

In order to make it work you need to convert key from str to tuple before decryption(ast.literal_eval function). Here is fixed code:

import Crypto
from Crypto.PublicKey import RSA
from Crypto import Random
import ast

random_generator = Random.new().read
key = RSA.generate(1024, random_generator) #generate pub and priv key

publickey = key.publickey() # pub key export for exchange

encrypted = publickey.encrypt('encrypt this message', 32)
#message to encrypt is in the above line 'encrypt this message'

print 'encrypted message:', encrypted #ciphertext
f = open ('encryption.txt', 'w')
f.write(str(encrypted)) #write ciphertext to file
f.close()

#decrypted code below

f = open('encryption.txt', 'r')
message = f.read()


decrypted = key.decrypt(ast.literal_eval(str(encrypted)))

print 'decrypted', decrypted

f = open ('encryption.txt', 'w')
f.write(str(message))
f.write(str(decrypted))
f.close()

Try this:

public partial class Service : ServiceBase
{
    private Timer timer;
    public Service()
    {
        InitializeComponent();
    }

    protected override void OnStart(string[] args)
    {
        SetTimer();
    }

    private void SetTimer()
    {
        if (timer == null)
        {
            timer = new Timer();
            timer.AutoReset = true;
            timer.Interval = 60000 * Convert.ToDouble(ConfigurationManager.AppSettings["IntervalMinutes"]);
            timer.Elapsed += new ElapsedEventHandler(timer_Elapsed);
            timer.Start();
        }
    }

    private void timer_Elapsed(object source, System.Timers.ElapsedEventArgs e)
    {
        //Do some thing logic here
    }

    protected override void OnStop()
    {
        // disposed all service objects
    }
}

Override the OnFormClosing method.

CAUTION: You need to check the CloseReason and only alter the behaviour if it is UserClosing. You should not put anything in here that would stall the Windows shutdown routine.

Application Shutdown Changes in Windows Vista

This is from the Windows 7 logo program requirements.

To add to those who have mentioned the implicit rules, it's best to see what make has defined implicitly and for your env using:

make -p

For instance:

%.o: %.c
    $(COMPILE.c) $(OUTPUT_OPTION) $<

which expands

COMPILE.c = $(CXX) $(CXXFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -c

This will also print # environment data. Here, you will find GCC's include path among other useful info.

C_INCLUDE_PATH=/usr/include

In make, when it comes to search, the paths are many, the light is one... or something to that effect.

1. C_INCLUDE_PATH is system-wide, set it in your shell's *.rc.
2. $(CPPFLAGS) is for the preprocessor include path.
3. If you need to add a general search path for make, use:

VPATH = my_dir_to_search

... or even more specific

vpath %.c src
vpath %.h include

make uses VPATH as a general search path so use cautiously. If a file exists in more than one location listed in VPATH, make will take the first occurrence in the list.

Unfortunately, there is a character limit so this will be in many parts. First thing to note is that return and print are statements, not functions, but that is just semantics.

I’ll start with a basic explanation. print just shows the human user a string representing what is going on inside the computer. The computer cannot make use of that printing. return is how a function gives back a value. This value is often unseen by the human user, but it can be used by the computer in further functions.

On a more expansive note, print will not in any way affect a function. It is simply there for the human user’s benefit. It is very useful for understanding how a program works and can be used in debugging to check various values in a program without interrupting the program.

return is the main way that a function returns a value. All functions will return a value, and if there is no return statement (or yield but don’t worry about that yet), it will return None. The value that is returned by a function can then be further used as an argument passed to another function, stored as a variable, or just printed for the benefit of the human user. Consider these two programs:

def function_that_prints():
    print "I printed"

def function_that_returns():
    return "I returned"

f1 = function_that_prints()
f2 = function_that_returns()

print "Now let us see what the values of f1 and f2 are"

print f1 --->None

print f2---->"I returned"

When function_that_prints ran, it automatically printed to the console "I printed". However, the value stored in f1 is None because that function had no return statement.

When function_that_returns ran, it did not print anything to the console. However, it did return a value, and that value was stored in f2. When we printed f2 at the end of the code, we saw "I returned"

The easiest option for me was to rename the title of the terminal instead. Please see: https://superuser.com/questions/362227/how-to-change-the-title-of-the-mintty-window

In this answer, they mention to modify the PS1 variable. Note: my situation was particular to cygwin.

TL;DR Put this in your .bashrc file:

function settitle() {
      export PS1="\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\n$ "
      echo -ne "\e]0;$1\a"
}

Put this in your .tmux.conf file, or similar formatting:

set -g pane-border-status bottom
set -g pane-border-format "#P #T #{pane_current_command}"

Then you can change the title of the pane by typing this in the console:

settitle titlename

Was fiddling round with someone elses code today and found the following which seems rounds down as well:

var dec = 12.3453465,
int = dec >> 0; // returns 12

For more info on the Sign-propagating right shift(>>) see MDN Bitwise Operators

It took me a while to work out what this was doing :D

But as highlighted above, Math.floor() works and looks more readable in my opinion.

Laravel 5.8

{{ request()->a }}

You need to define something in the interface, such as:

public interface ITest
{
    string Name { get; }
}

Implement ITest in your classes:

public class MyClass1 : ITest
{
    public string Name { get { return "Test1"; } }
}

public class MyClass2 : ITest
{
    public string Name { get { return "Test2"; } }
}

Then restrict your generic Print function, to ITest:

public void Print<T>(T test) where T : ITest
{
}

Boto 2's boto.s3.key.Key object used to have an exists method that checked if the key existed on S3 by doing a HEAD request and looking at the the result, but it seems that that no longer exists. You have to do it yourself:

import boto3
import botocore

s3 = boto3.resource('s3')

try:
    s3.Object('my-bucket', 'dootdoot.jpg').load()
except botocore.exceptions.ClientError as e:
    if e.response['Error']['Code'] == "404":
        # The object does not exist.
        ...
    else:
        # Something else has gone wrong.
        raise
else:
    # The object does exist.
    ...

load() does a HEAD request for a single key, which is fast, even if the object in question is large or you have many objects in your bucket.

Of course, you might be checking if the object exists because you're planning on using it. If that is the case, you can just forget about the load() and do a get() or download_file() directly, then handle the error case there.

For Linux Mint, this problem is actually referenced in the Docker website:

Note: The lsb_release -cs sub-command below returns the name of your Ubuntu distribution, such as xenial. Sometimes, in a distribution like Linux Mint, you might have to change $(lsb_release -cs) to your parent Ubuntu distribution. For example, if you are using Linux Mint Rafaela, you could use trusty.

amd64:

$ sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"

The lsb_release -cs command gives a repository for which Docker has no prepared package - you must change it to xenial.

The correct command for Linux Mint 18 which is based on Ubuntu 16.04 Xenial is

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   xenial \
   stable"

A web application is a software program which a user accesses over an internal network, or via the internet through a web browser. An example of one of the most widely used web applications is Google Docs, which facilitates most of the capabilities of Microsoft Word; it’s free and easy to use from any location.

A web site, on the other hand, is a collection of documents that are accessed via the internet through a web browser. Web sites can also contain web applications, which allow visitors to complete online tasks such as: Search, View, Buy, Checkout, and Pay.

Run this command :

    sudo chown -R yourUser /home/yourUser/.composer

@amro's answer translated to Swift 4.0:

I found this works more easily than getting an index. For my needs, I am selecting a tab based off a url hash

var target = window.location.hash.replace(/#/,'#tab-');
if (target) { 
    jQuery('a[href='+target+']').click().parent().trigger('keydown');      
}   

On Windows I use this code:

void * G_pPointer = NULL;
const char * G_szPointerName = NULL;
void CheckPointerIternal()
{
    char cTest = *((char *)G_pPointer);
}
bool CheckPointerIternalExt()
{
    bool bRet = false;

    __try
    {
        CheckPointerIternal();
        bRet = true;
    }
    __except (EXCEPTION_EXECUTE_HANDLER)
    {
    }

    return  bRet;
}
void CheckPointer(void * A_pPointer, const char * A_szPointerName)
{
    G_pPointer = A_pPointer;
    G_szPointerName = A_szPointerName;
    if (!CheckPointerIternalExt())
        throw std::runtime_error("Invalid pointer " + std::string(G_szPointerName) + "!");
}

Usage:

unsigned long * pTest = (unsigned long *) 0x12345;
CheckPointer(pTest, "pTest"); //throws exception

<TextBlock Text="{Binding Date, StringFormat='{}{0:MM/dd/yyyy a\\t h:mm tt}'}" />

Assuming you're using the mysql_ or mysqli_ functions, your question should already have been answered by others.

However if you're using PDO, there is no easy function to return the number of rows retrieved by a select statement, unfortunately. You have to use count() on the resultset (after assigning it to a local variable, usually).

Or if you're only interested in the number and not the data, PDOStatement::fetchColumn() on your SELECT COUNT(1)... result.

This what I came up with, since I need to run several operations in a chain.

<button onclick="tprom('Hello Niclas')">test promise</button>

Didn't work with ODBC-Bridge for me too. I got the way around to initialize ODBC connection using ODBC driver.

 import java.sql.*;  
 public class UserLogin
 {
     public static void main(String[] args)
     {
        try
        {    
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

            // C:\\databaseFileName.accdb" - location of your database 
           String url = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=" + "C:\\emp.accdb";

            // specify url, username, pasword - make sure these are valid 
            Connection conn = DriverManager.getConnection(url, "username", "password");

            System.out.println("Connection Succesfull");
         } 
         catch (Exception e) 
         {
            System.err.println("Got an exception! ");
            System.err.println(e.getMessage());

          }
      }
  }

You can use "find" for remove all files in the /objects directory with 0 in size with the command:

find .git/objects/ -size 0 -delete

Backup is recommended.

Just another method....

what about using aggregate framework:

db.collection.aggregate({ $group : { _id: null, max: { $max : "$age" }}});

YES!! There is a way to detach a busy device immediately - even if it is busy and cannot be unmounted forcefully. You may cleanup all later:

umount -l /PATH/OF/BUSY-DEVICE
umount -f /PATH/OF/BUSY-NFS (NETWORK-FILE-SYSTEM)

NOTE/CAUTION

1. These commands can disrupt a running process, cause data loss OR corrupt open files. Programs accessing target DEVICE/NFS files may throw errors OR could not work properly after force unmount.
2. Do not execute above umount commands when inside mounted path (Folder/Drive/Device) itself. First, you may use pwd command to validate your current directory path (which should not be the mounted path), then use cd command to get out of the mounted path - to unmount it later using above commands.

This is the one I found here that worked for me:

(EDIT: I have updated the solution using @Micah's suggestion to increase the pointRect by 0.1 to ensure the rect doesn't end up being infinitesimally small!)

MKMapRect zoomRect = MKMapRectNull;
for (id <MKAnnotation> annotation in mapView.annotations)
{
    MKMapPoint annotationPoint = MKMapPointForCoordinate(annotation.coordinate);
    MKMapRect pointRect = MKMapRectMake(annotationPoint.x, annotationPoint.y, 0.1, 0.1);
    zoomRect = MKMapRectUnion(zoomRect, pointRect);
}
[mapView setVisibleMapRect:zoomRect animated:YES];

You could also update this to include the userLocation pin by replacing the first line with:

MKMapPoint annotationPoint = MKMapPointForCoordinate(mapView.userLocation.coordinate);
MKMapRect zoomRect = MKMapRectMake(annotationPoint.x, annotationPoint.y, 0.1, 0.1);

I use system properties in log4j.xml:

In My cases, After installing Sql server data tools by Visual Studio 2015 installer, problem has been resolved

Here is the screenshot for installing data tools

First: Even the unique IDs generated by java UUID.randomUUID or .net GUID are not 100% unique. Especialy UUID.randomUUID is "only" a 128 bit (secure) random value. So if you reduce it to 64 bit, 32 bit, 16 bit (or even 1 bit) then it becomes simply less unique.

So it is at least a risk based decisions, how long your uuid must be.

Second: I assume that when you talk about "only 8 characters" you mean a String of 8 normal printable characters.

If you want a unique string with length 8 printable characters you could use a base64 encoding. This means 6bit per char, so you get 48bit in total (possible not very unique - but maybe it is ok for you application)

So the way is simple: create a 6 byte random array

 SecureRandom rand;
 // ...
 byte[] randomBytes = new byte[16];
 rand.nextBytes(randomBytes);

And then transform it to a Base64 String, for example by org.apache.commons.codec.binary.Base64

BTW: it depends on your application if there is a better way to create "uuid" then by random. (If you create a the UUIDs only once per second, then it is a good idea to add a time stamp) (By the way: if you combine (xor) two random values, the result is always at least as random as the most random of the both).

The Content-Security-Policy meta-tag allows you to reduce the risk of XSS attacks by allowing you to define where resources can be loaded from, preventing browsers from loading data from any other locations. This makes it harder for an attacker to inject malicious code into your site.

I banged my head against a brick wall trying to figure out why I was getting CSP errors one after another, and there didn't seem to be any concise, clear instructions on just how does it work. So here's my attempt at explaining some points of CSP briefly, mostly concentrating on the things I found hard to solve.

For brevity I won’t write the full tag in each sample. Instead I'll only show the content property, so a sample that says content="default-src 'self'" means this:

<meta http-equiv="Content-Security-Policy" content="default-src 'self'">

1. How can I allow multiple sources?

You can simply list your sources after a directive as a space-separated list:

content="default-src 'self' https://example.com/js/"

Note that there are no quotes around parameters other than the special ones, like 'self'. Also, there's no colon (:) after the directive. Just the directive, then a space-separated list of parameters.

Everything below the specified parameters is implicitly allowed. That means that in the example above these would be valid sources:

https://example.com/js/file.js
https://example.com/js/subdir/anotherfile.js

These, however, would not be valid:

http://example.com/js/file.js
^^^^ wrong protocol

https://example.com/file.js
                   ^^ above the specified path

2. How can I use different directives? What do they each do?

The most common directives are:

• default-src the default policy for loading javascript, images, CSS, fonts, AJAX requests, etc
• script-src defines valid sources for javascript files
• style-src defines valid sources for css files
• img-src defines valid sources for images
• connect-src defines valid targets for to XMLHttpRequest (AJAX), WebSockets or EventSource. If a connection attempt is made to a host that's not allowed here, the browser will emulate a 400 error

There are others, but these are the ones you're most likely to need.

3. How can I use multiple directives?

You define all your directives inside one meta-tag by terminating them with a semicolon (;):

content="default-src 'self' https://example.com/js/; style-src 'self'"

4. How can I handle ports?

Everything but the default ports needs to be allowed explicitly by adding the port number or an asterisk after the allowed domain:

content="default-src 'self' https://ajax.googleapis.com http://example.com:123/free/stuff/"

The above would result in:

https://ajax.googleapis.com:123
                           ^^^^ Not ok, wrong port

https://ajax.googleapis.com - OK

http://example.com/free/stuff/file.js
                 ^^ Not ok, only the port 123 is allowed

http://example.com:123/free/stuff/file.js - OK

As I mentioned, you can also use an asterisk to explicitly allow all ports:

content="default-src example.com:*"

5. How can I handle different protocols?

By default, only standard protocols are allowed. For example to allow WebSockets ws:// you will have to allow it explicitly:

content="default-src 'self'; connect-src ws:; style-src 'self'"
                                         ^^^ web Sockets are now allowed on all domains and ports.

6. How can I allow the file protocol file://?

If you'll try to define it as such it won’t work. Instead, you'll allow it with the filesystem parameter:

content="default-src filesystem"

7. How can I use inline scripts and style definitions?

Unless explicitly allowed, you can't use inline style definitions, code inside <script> tags or in tag properties like onclick. You allow them like so:

content="script-src 'unsafe-inline'; style-src 'unsafe-inline'"

You'll also have to explicitly allow inline, base64 encoded images:

content="img-src data:"

8. How can I allow eval()?

I'm sure many people would say that you don't, since 'eval is evil' and the most likely cause for the impending end of the world. Those people would be wrong. Sure, you can definitely punch major holes into your site's security with eval, but it has perfectly valid use cases. You just have to be smart about using it. You allow it like so:

content="script-src 'unsafe-eval'"

9. What exactly does 'self' mean?

You might take 'self' to mean localhost, local filesystem, or anything on the same host. It doesn't mean any of those. It means sources that have the same scheme (protocol), same host, and same port as the file the content policy is defined in. Serving your site over HTTP? No https for you then, unless you define it explicitly.

I've used 'self' in most examples as it usually makes sense to include it, but it's by no means mandatory. Leave it out if you don't need it.

But hang on a minute! Can't I just use content="default-src *" and be done with it?

No. In addition to the obvious security vulnerabilities, this also won’t work as you'd expect. Even though some docs claim it allows anything, that's not true. It doesn't allow inlining or evals, so to really, really make your site extra vulnerable, you would use this:

content="default-src * 'unsafe-inline' 'unsafe-eval'"

... but I trust you won’t.

I have the same wonder today, I did on this way :

//<img src="actual.png" alt="myImage" class=myClass>
$('.myClass').attr('src','').promise().done(function() {
$(this).attr('src','img/new.png');  
});

In addition to @Emilia Apostolova answer to get the ground truth labels, from

generator = train_datagen.flow_from_directory("train", batch_size=batch_size)

just call

y_true_labels = generator.classes

Using CURL Windows, try this:

curl -X POST -H "Content-Type:application/json" -d "{\"firstName\": \"blablabla\",\"lastName\": \"dummy\",\"id\": \"123456\"}" http-host/_ah/api/employeeendpoint/v1/employee

You could try this, but performance may be worse a little:

@Dao
public abstract class TourDao {

    @Query("SELECT * FROM Tour WHERE id == :id")
    public abstract Tour getTour(int id);

    @Update
    public abstract int updateTour(Tour tour);

    public void updateTour(int id, String end_address) {
        Tour tour = getTour(id);
        tour.end_address = end_address;
        updateTour(tour);
    }
}

Let's fit the model:

> library(ISwR)
> fit <- lm(metabolic.rate ~ body.weight, rmr)
> summary(fit)

Call:
lm(formula = metabolic.rate ~ body.weight, data = rmr)

Residuals:
    Min      1Q  Median      3Q     Max 
-245.74 -113.99  -32.05  104.96  484.81 

Coefficients:
            Estimate Std. Error t value Pr(>|t|)

---
Signif. codes:  0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1 

Residual standard error: 157.9 on 42 degrees of freedom
Multiple R-squared: 0.5539, Adjusted R-squared: 0.5433 
F-statistic: 52.15 on 1 and 42 DF,  p-value: 7.025e-09 

The 95% confidence interval for the slope is the estimated coefficient (7.0595) ± two standard errors (0.9776).

This can be computed using confint:

> confint(fit, 'body.weight', level=0.95)
               2.5 % 97.5 %
body.weight 5.086656 9.0324

Actualy the Gabin Smith's answer needs to be changed a bit to work, because you can't resume with without an error.

Sub MyFunc()
...
    For Each oSheet In ActiveWorkbook.Sheets
        On Error GoTo errHandler:
        Set qry = oSheet.ListObjects(1).QueryTable
        oCmbBox.AddItem oSheet.name

    ...
NextSheet:
    Next oSheet

...
Exit Sub

errHandler:
Resume NextSheet        
End Sub

Your code works well you just mistyped this line of code:

document.getElementbyId('lc').appendChild(element);

change it with this: (The "B" should be capitalized.)

document.getElementById('lc').appendChild(element);  

HERE IS MY EXAMPLE:

<html>_x000D_
<head>_x000D_
_x000D_
<script>_x000D_
_x000D_
function test() {_x000D_
_x000D_
    var element = document.createElement("div");_x000D_
    element.appendChild(document.createTextNode('The man who mistook his wife for a hat'));_x000D_
    document.getElementById('lc').appendChild(element);_x000D_
_x000D_
}_x000D_
_x000D_
</script>_x000D_

<input id="filter" type="text" placeholder="Enter your filter text here.." onkeyup = "test()" />_x000D_
_x000D_
<div id="lc" style="background: blue; height: 150px; width: 150px;_x000D_
}" onclick="test();">  _x000D_

What's probably happening is that React thinks that only one MyInput (unemployment-duration) is added between the renders. As such, the job-title never gets replaced with the unemployment-reason, which is also why the predefined values are swapped.

When React does the diff, it will determine which components are new and which are old based on their key property. If no such key is provided in the code, it will generate its own.

The reason why the last code snippet you provide works is because React essentially needs to change the hierarchy of all elements under the parent div and I believe that would trigger a re-render of all children (which is why it works). Had you added the span to the bottom instead of the top, the hierarchy of the preceding elements wouldn't change, and those element's wouldn't re-render (and the problem would persist).

Here's what the official React documentation says:

The situation gets more complicated when the children are shuffled around (as in search results) or if new components are added onto the front of the list (as in streams). In these cases where the identity and state of each child must be maintained across render passes, you can uniquely identify each child by assigning it a key.

When React reconciles the keyed children, it will ensure that any child with key will be reordered (instead of clobbered) or destroyed (instead of reused).

You should be able to fix this by providing a unique key element yourself to either the parent div or to all MyInput elements.

For example:

render(){
    if (this.state.employed) {
        return (
            <div key="employed">
                <MyInput ref="job-title" name="job-title" />
            </div>
        );
    } else {
        return (
            <div key="notEmployed">
                <MyInput ref="unemployment-reason" name="unemployment-reason" />
                <MyInput ref="unemployment-duration" name="unemployment-duration" />
            </div>
        );
    }
}

OR

render(){
    if (this.state.employed) {
        return (
            <div>
                <MyInput key="title" ref="job-title" name="job-title" />
            </div>
        );
    } else {
        return (
            <div>
                <MyInput key="reason" ref="unemployment-reason" name="unemployment-reason" />
                <MyInput key="duration" ref="unemployment-duration" name="unemployment-duration" />
            </div>
        );
    }
}

Now, when React does the diff, it will see that the divs are different and will re-render it including all of its' children (1st example). In the 2nd example, the diff will be a success on job-title and unemployment-reason since they now have different keys.

You can of course use any keys you want, as long as they are unique.

Update August 2017

For a better insight into how keys work in React, I strongly recommend reading my answer to Understanding unique keys in React.js.

Update November 2017

This update should've been posted a while ago, but using string literals in ref is now deprecated. For example ref="job-title" should now instead be ref={(el) => this.jobTitleRef = el} (for example). See my answer to Deprecation warning using this.refs for more info.

The javadoc of NoClassDefFounError itself would be a good start (here), and then I'll suggest you clean and rebuild your project.

When you are storing a DataFrame object into a csv file using the to_csv method, you probably wont be needing to store the preceding indices of each row of the DataFrame object.

You can avoid that by passing a False boolean value to index parameter.

Somewhat like:

df.to_csv(file_name, encoding='utf-8', index=False)

So if your DataFrame object is something like:

  Color  Number
0   red     22
1  blue     10

The csv file will store:

Color,Number
red,22
blue,10

instead of (the case when the default value True was passed)

,Color,Number
0,red,22
1,blue,10

Here is a good discussion on the topic. Gavin King recommends @Inject over @EJB for non remote EJBs.

Re: Injecting with @EJB or @Inject?

26. Nov 2009, 20:48 America/New_York | Link Gavin King

That error is very strange, since EJB local references should always be serializable. Bug in glassfish, perhaps?

Basically, @Inject is always better, since:

it is more typesafe,
it supports @Alternatives, and
it is aware of the scope of the injected object.

I recommend against the use of @EJB except for declaring references to remote EJBs.

and

Re: Injecting with @EJB or @Inject?

29. Nov 2009, 17:42 America/New_York | Link Gavin King

    Does it mean @EJB better with remote EJBs?

For a remote EJB, we can't declare metadata like qualifiers, @Alternative, etc, on the bean class, since the client simply isn't going to have access to that metadata. Furthermore, some additional metadata must be specified that we don't need for the local case (global JNDI name of whatever). So all that stuff needs to go somewhere else: namely the @Produces declaration.

You can sharpen an image using an unsharp mask. You can find more information about unsharp masking here. And here's a Python implementation using OpenCV:

import cv2 as cv
import numpy as np

def unsharp_mask(image, kernel_size=(5, 5), sigma=1.0, amount=1.0, threshold=0):
    """Return a sharpened version of the image, using an unsharp mask."""
    blurred = cv.GaussianBlur(image, kernel_size, sigma)
    sharpened = float(amount + 1) * image - float(amount) * blurred
    sharpened = np.maximum(sharpened, np.zeros(sharpened.shape))
    sharpened = np.minimum(sharpened, 255 * np.ones(sharpened.shape))
    sharpened = sharpened.round().astype(np.uint8)
    if threshold > 0:
        low_contrast_mask = np.absolute(image - blurred) < threshold
        np.copyto(sharpened, image, where=low_contrast_mask)
    return sharpened

def example():
    image = cv.imread('my-image.jpg')
    sharpened_image = unsharp_mask(image)
    cv.imwrite('my-sharpened-image.jpg', sharpened_image)

I have found this to work best for big data.

SELECT TOP 1 Column_Name FROM dbo.Table TABLESAMPLE(1 PERCENT);

TABLESAMPLE(n ROWS) or TABLESAMPLE(n PERCENT) is random but need to add the TOP n to get the correct sample size.

Using NEWID() is very slow on large tables.

You probably want to use a CASE expression.

They look like this:

SELECT col1, col2, (case when (action = 2 and state = 0) 
 THEN
      1 
 ELSE
      0 
 END)
 as state from tbl1;

One way, I haven't seen mentioned that can be a bit more robust, particularly if you wanted to alter each element in some way (e.g. you wanted to .Trim() all of the elements.

List<string> a = new List<string>();
List<string> b = new List<string>();
// ...
b.ForEach(x=>a.Add(x.Trim()));

The encodings are spelled out in the buffer documentation.

Buffers and character encodings:

Character Encodings

• utf8: Multi-byte encoded Unicode characters. Many web pages and other document formats use UTF-8. This is the default character encoding.
• utf16le: Multi-byte encoded Unicode characters. Unlike utf8, each character in the string will be encoded using either 2 or 4 bytes.
• latin1: Latin-1 stands for ISO-8859-1. This character encoding only supports the Unicode characters from U+0000 to U+00FF.

Binary-to-Text Encodings

• base64: Base64 encoding. When creating a Buffer from a string, this encoding will also correctly accept "URL and Filename Safe Alphabet" as specified in RFC 4648, Section 5.
• hex: Encode each byte as two hexadecimal characters.

Legacy Character Encodings

• ascii: For 7-bit ASCII data only. Generally, there should be no reason to use this encoding, as 'utf8' (or, if the data is known to always be ASCII-only, 'latin1') will be a better choice when encoding or decoding ASCII-only text.
• binary: Alias for 'latin1'.
• ucs2: Alias of 'utf16le'.

Use :

FileInfo fInfo = new FileInfo('FilePath');
var fFirstTime = fInfo.CreationTime;
var fLastTime = fInfo.LastWriteTime;

Your title and comments imply that you weren't looking for a sticky footer (stuck to the bottom of the window as content scrolls below it). I assume you were looking for a footer that would be forced to the bottom of the window if the content does not fill the window, and push down to the bottom of the content if the content exceeds the window boundary.

You can accomplish this with the following.

<style>
html,
body {
    margin:0;
    padding:0;
    height:100%;
}
#container {
    min-height:100%;
    position:relative;
}
#header {
    background:#ff0;
    padding:10px;
}
#body {
    padding:10px;
    padding-bottom:60px;   /* Height of the footer */
}
#footer {
    position:absolute;
    bottom:0;
    width:100%;
    height:60px;   /* Height of the footer */
    background:#6cf;
}
</style>

<div id="container">
    <div id="header">header</div>
    <div id="body">body</div>
    <div id="footer">footer</div>
</div>

How to print the full traceback without halting the program?

When you don't want to halt your program on an error, you need to handle that error with a try/except:

try:
    do_something_that_might_error()
except Exception as error:
    handle_the_error(error)

To extract the full traceback, we'll use the traceback module from the standard library:

import traceback

And to create a decently complicated stacktrace to demonstrate that we get the full stacktrace:

def raise_error():
    raise RuntimeError('something bad happened!')

def do_something_that_might_error():
    raise_error()

Printing

To print the full traceback, use the traceback.print_exc method:

try:
    do_something_that_might_error()
except Exception as error:
    traceback.print_exc()

Which prints:

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "<stdin>", line 2, in do_something_that_might_error
  File "<stdin>", line 2, in raise_error
RuntimeError: something bad happened!

Better than printing, logging:

However, a best practice is to have a logger set up for your module. It will know the name of the module and be able to change levels (among other attributes, such as handlers)

import logging
logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger(__name__)

In which case, you'll want the logger.exception function instead:

try:
    do_something_that_might_error()
except Exception as error:
    logger.exception(error)

Which logs:

ERROR:__main__:something bad happened!
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "<stdin>", line 2, in do_something_that_might_error
  File "<stdin>", line 2, in raise_error
RuntimeError: something bad happened!

Or perhaps you just want the string, in which case, you'll want the traceback.format_exc function instead:

try:
    do_something_that_might_error()
except Exception as error:
    logger.debug(traceback.format_exc())

Which logs:

DEBUG:__main__:Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
  File "<stdin>", line 2, in do_something_that_might_error
  File "<stdin>", line 2, in raise_error
RuntimeError: something bad happened!

Conclusion

And for all three options, we see we get the same output as when we have an error:

>>> do_something_that_might_error()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in do_something_that_might_error
  File "<stdin>", line 2, in raise_error
RuntimeError: something bad happened!

Which to use

Performance concerns aren't important here as IO usually dominates. I'd prefer, since it does precisely what's being requested in a forward compatible way:

logger.exception(error)

Logging levels and outputs can be adjusted, making it easy to turn off without touching the code. And usually doing what's directly needed is the most efficient way to do it.

You can concat many kind of expression by sorrounding your simple/complex expression between || characters:

<p th:text="|${bean.field} ! ${bean.field}|">Static content</p>

On your own system, try

install.packages("foo", dependencies=...)

with the dependencies= argument is documented as

dependencies: logical indicating to also install uninstalled packages
      which these packages depend on/link to/import/suggest (and so
      on recursively).  Not used if ‘repos = NULL’.  Can also be a
      character vector, a subset of ‘c("Depends", "Imports",
      "LinkingTo", "Suggests", "Enhances")’.

      Only supported if ‘lib’ is of length one (or missing), so it
      is unambiguous where to install the dependent packages.  If
      this is not the case it is ignored, with a warning.

      The default, ‘NA’, means ‘c("Depends", "Imports",
      "LinkingTo")’.

      ‘TRUE’ means (as from R 2.15.0) to use ‘c("Depends",
      "Imports", "LinkingTo", "Suggests")’ for ‘pkgs’ and
      ‘c("Depends", "Imports", "LinkingTo")’ for added
      dependencies: this installs all the packages needed to run
      ‘pkgs’, their examples, tests and vignettes (if the package
      author specified them correctly).

so you probably want a value TRUE.

In your package, list what is needed in Depends:, see the Writing R Extensions manual which is pretty clear on this.

just use a regex as a separator:

', *' - for leading spaces

' *,' - for trailing spaces

for both leading and trailing:

awk -F' *,? *' '{print $1","$2}' input.txt

/^[0-9\+]{1,}[0-9\-]{3,15}$/

so first is a digit or a +, then some digits or -

@ Mike Eng,

On selecting the text background color, text color can be changed with the help of ::selection, note that ::selection works in in chrome, to make that work in firefox based browsers try this one ::-moz-selection

Try the following snippet of code in reset.css or the css page where exactly you want to apply the effect.

::selection{
   //Works only for the chrome browsers
   background-color: #CFCFCF; //This turns the background color to Gray
   color: #000; // This turns the selected font color to Black
}

::-moz-selection{
   //Works for the firefox based browsers
   background-color: #CFCFCF; //This turns the background color to Gray
   color: #000; // This turns the selected font color to Black
}

The above code will work even in the input boxes too.

A few of the other answers recommend merging/committing within the submodule's directory, which IMO can become a little messy.

Assuming the remote server is named origin and we want the master branch of the submodule(s), I tend to use:

git submodule foreach "git fetch && git reset --hard origin/master"

Note: This will perform a hard reset on each submodule -- if you don't want this, you can change --hard to --soft.

Wow, this one took me a while to solve, as I was using SVN through Eclipse. In the end, the only thing that worked for me was to commit all non-affected files, then (with Eclipse closed) rename the project directory, and re-check the project out from SVN. Glad it works properly now!

For some reason, in some cases I couldn't make the setDate work.

A workaround I found is to simply update the value attribute of the given input. Of course the datepicker itself won't be updated but if what you just look for is to display the date, it works fine.

var date = new Date(2008,9,3);
$("#your-input").val(date.getMonth()+"/"+date.getDate()+"/"+date.getFullYear());
// Will display 9/3/2008 in your #your-input input

I am doing it like

public enum State
{
    // Retrieving, // the MediaRetriever is retrieving music //
    Stopped, // media player is stopped and not prepared to play
    Preparing, // media player is preparing...
    Playing, // playback active (media player ready!). (but the media player
                // may actually be
                // paused in this state if we don't have audio focus. But we
                // stay in this state
                // so that we know we have to resume playback once we get
                // focus back)
    Paused; // playback paused (media player ready!)

    //public final static State[] vals = State.values();//copy the values(), calling values() clones the array

};

public State getState()
{
        return mState;   
}

And use in Switch Statement

switch (mService.getState())
{
case Stopped:
case Paused:

    playPause.setBackgroundResource(R.drawable.selplay);
    break;

case Preparing:
case Playing:

    playPause.setBackgroundResource(R.drawable.selpause);
    break;    
}

Method overriding is when a child class redefines the same method as a parent class, with the same parameters. For example, the standard Java class java.util.LinkedHashSet extends java.util.HashSet. The method add() is overridden in LinkedHashSet. If you have a variable that is of type HashSet, and you call its add() method, it will call the appropriate implementation of add(), based on whether it is a HashSet or a LinkedHashSet. This is called polymorphism.

Method overloading is defining several methods in the same class, that accept different numbers and types of parameters. In this case, the actual method called is decided at compile-time, based on the number and types of arguments. For instance, the method System.out.println() is overloaded, so that you can pass ints as well as Strings, and it will call a different version of the method.

I always use the x:Name variant. I have no idea if this affects any performance, I just find it easier for the following reason. If you have your own usercontrols that reside in another assembly just the "Name" property won't always suffice. This makes it easier to just stick too the x:Name property.

Here's a generic version of a sproc I recently wrote for Oracle that allows for dynamic paging/sorting - HTH

-- p_LowerBound = first row # in the returned set; if second page of 10 rows,
--                this would be 11 (-1 for unbounded/not set)
-- p_UpperBound = last row # in the returned set; if second page of 10 rows,

Another alternative is to use the heatmap function in seaborn to plot the covariance. This example uses the Auto data set from the ISLR package in R (the same as in the example you showed).

import pandas.rpy.common as com
import seaborn as sns
%matplotlib inline

# load the R package ISLR
infert = com.importr("ISLR")

# load the Auto dataset
auto_df = com.load_data('Auto')

# calculate the correlation matrix
corr = auto_df.corr()

# plot the heatmap
sns.heatmap(corr, 
        xticklabels=corr.columns,
        yticklabels=corr.columns)

If you wanted to be even more fancy, you can use Pandas Style, for example:

cmap = cmap=sns.diverging_palette(5, 250, as_cmap=True)

def magnify():
    return [dict(selector="th",
                 props=[("font-size", "7pt")]),
            dict(selector="td",
                 props=[('padding', "0em 0em")]),
            dict(selector="th:hover",
                 props=[("font-size", "12pt")]),
            dict(selector="tr:hover td:hover",
                 props=[('max-width', '200px'),
                        ('font-size', '12pt')])
]

corr.style.background_gradient(cmap, axis=1)\
    .set_properties(**{'max-width': '80px', 'font-size': '10pt'})\
    .set_caption("Hover to magify")\
    .set_precision(2)\
    .set_table_styles(magnify())

Here is a basic example of how an image file with certain restrictions (listed below) can be uploaded to the server.

• Existence of the image.
• Image extension validation

• Checks for image size.

  <?php
     $newfilename = "newfilename";
  
     if(isset($_FILES['image'])){
        $errors= array();
        $file_name = $_FILES['image']['name'];
        $file_size =$_FILES['image']['size'];
        $file_tmp =$_FILES['image']['tmp_name'];
        $file_type=$_FILES['image']['type'];
        $file_ext=strtolower(end(explode('.',$_FILES['image']['name'])));
  
        $expensions= array("jpeg","jpg","png");
        if(file_exists($file_name)) {
          echo "Sorry, file already exists.";
          }
        if(in_array($file_ext,$expensions)=== false){
           $errors[]="extension not allowed, please choose a JPEG or PNG file.";
        }
  
        if($file_size > 2097152){
           $errors[]='File size must be excately 2 MB';
        }
  
        if(empty($errors)==true){
          move_uploaded_file($file_tmp,"images/".$newfilename.".".$file_ext);
          echo "Success";
          echo "<script>window.close();</script>";
  
        }
  
        else{
           print_r($errors);
        }
     }

The pointsize command scales the size of points, but does not affect the size of dots.

In other words, plot ... with points ps 2 will generate points of twice the normal size, but for plot ... with dots ps 2 the "ps 2" part is ignored.

You could use circular points (pt 7), which look just like dots.

All these answers are nice however when thinking about it....
Sometimes the most simple approach without sophistication will do the trick quicker and with no special functions.

We first set the arrays:

$arr1 = Array(
"cod" => ddd,
"denum" => ffffffffffffffff,
"descr" => ggggggg,
"cant" => 3
);
$arr2 = Array
(
"cod" => fff,
"denum" => dfgdfgdfgdfgdfg,
"descr" => dfgdfgdfgdfgdfg,
"cant" => 33
);

Then we add them to the new array :

$newArr[] = $arr1;
$newArr[] = $arr2;

Now lets see our new array with all the keys:

print_r($newArr);

There's no need for sql or special functions to build a new multi-dimensional array.... don't use a tank to get to where you can walk.

Answered my own question. Sigh

http://docs.djangoproject.com/en/dev/ref/forms/widgets/#django.forms.Widget.attrs

I didn't realize it was passed into the widget constructor.

FAQ says:

If you have

varname <- c("a", "b", "d")

you can do

get(varname[1]) + 2

for

a + 2

or

assign(varname[1], 2 + 2)

for

a <- 2 + 2

So it looks like you use GET when you want to evaluate a formula that uses a variable (such as a concatenate), and ASSIGN when you want to assign a value to a pre-declared variable.

Syntax for assign: assign(x, value)

x: a variable name, given as a character string. No coercion is done, and the first element of a character vector of length greater than one will be used, with a warning.

value: value to be assigned to x.

You can as long as

• The value is unique
• No existing foreign keys are violated

The key difference in a nutshell is that reset moves the current branch reference, while checkout does not (it moves HEAD).

As the Pro Git book explains under Reset Demystified,

The first thing reset will do is move what HEAD points to. This isn’t the same as changing HEAD itself (which is what checkout does); reset moves the branch that HEAD is pointing to. This means if HEAD is set to the master branch (i.e. you’re currently on the master branch), running git reset 9e5e6a4 will start by making master point to 9e5e6a4. [emphasis added]

See also VonC's answer for a very helpful text and diagram excerpt from the same article, which I won't duplicate here.

Of course there are a lot more details about what effects checkout and reset can have on the index and the working tree, depending on what parameters are used. There can be lots of similarities and differences between the two commands. But as I see it, the most crucial difference is whether they move the tip of the current branch.

in my case innodb_data_home_dir was no longer correct because I had shuffled some drive letters around when I added a new drive to my system

Next to the performance issues, there is another one very important which I'd call code maintainability and extendibility.

If a T is POD and you start preferring initialization list, then if one time T will change to a non-POD type, you won't need to change anything around initialization to avoid unnecessary constructor calls because it is already optimised.

If type T does have default constructor and one or more user-defined constructors and one time you decide to remove or hide the default one, then if initialization list was used, you don't need to update code if your user-defined constructors because they are already correctly implemented.

Same with const members or reference members, let's say initially T is defined as follows:

struct T
{
    T() { a = 5; }
private:
    int a;
};

Next, you decide to qualify a as const, if you would use initialization list from the beginning, then this was a single line change, but having the T defined as above, it also requires to dig the constructor definition to remove assignment:

struct T
{
    T() : a(5) {} // 2. that requires changes here too
private:
    const int a; // 1. one line change
};

It's not a secret that maintenance is far easier and less error-prone if code was written not by a "code monkey" but by an engineer who makes decisions based on deeper consideration about what he is doing.

First, checkout to your Branch3:

git checkout Branch3

Then merge the Branch1:

git merge Branch1

And if you want the updated commits of Branch1 on Branch2, you are probaly looking for git rebase

git checkout Branch2
git rebase Branch1

This will update your Branch2 with the latest updates of Branch1.

This is very simple and straight forward. Look at the code. Try to grasp the basic concept behind javascript extension.

First let us extend javascript function.

function Base(props) {
    const _props = props
    this.getProps = () => _props

    // We can make method private by not binding it to this object. 
    // Hence it is not exposed when we return this.
    const privateMethod = () => "do internal stuff" 

    return this
}

You can extend this function by creating child function in following way

function Child(props) {
    const parent = Base(props)
    this.getMessage = () => `Message is ${parent.getProps()}`;

    // You can remove the line below to extend as in private inheritance, 
    // not exposing parent function properties and method.
    this.prototype = parent
    return this
}

Now you can use Child function as follows,

let childObject = Child("Secret Message")
console.log(childObject.getMessage())     // logs "Message is Secret Message"
console.log(childObject.getProps())       // logs "Secret Message"

We can also create Javascript Function by extending Javascript classes, like this.

class BaseClass {
    constructor(props) {
        this.props = props
        // You can remove the line below to make getProps method private. 
        // As it will not be binded to this, but let it be
        this.getProps = this.getProps.bind(this)
    }

    getProps() {
        return this.props
    }
}

Let us extend this class with Child function like this,

function Child(props) {
    let parent = new BaseClass(props)
    const getMessage = () => `Message is ${parent.getProps()}`;
    return { ...parent, getMessage} // I have used spread operator. 
}

Again you can use Child function as follows to get similar result,

let childObject = Child("Secret Message")
console.log(childObject.getMessage())     // logs "Message is Secret Message"
console.log(childObject.getProps())       // logs "Secret Message"

Javascript is very easy language. We can do almost anything. Happy JavaScripting... Hope I was able to give you an idea to use in your case.

Consolidating the answer from franksands into a convenient method.

import calendar
import datetime

def to_local_datetime(utc_dt):
    """
    convert from utc datetime to a locally aware datetime according to the host timezone

    :param utc_dt: utc datetime
    :return: local timezone datetime
    """
    return datetime.datetime.fromtimestamp(calendar.timegm(utc_dt.timetuple()))

Double.parseDouble(p.replace(',','.'))

...is very quick as it searches the underlying character array on a char-by-char basis. The string replace versions compile a RegEx to evaluate.

Basically replace(char,char) is about 10 times quicker and since you'll be doing these kind of things in low-level code it makes sense to think about this. The Hot Spot optimiser will not figure it out... Certainly doesn't on my system.

None of the above answers worked for me. On macOS Mojave, open console app, you may see an error like this:

001076.240057 adb@(null): IOUSBUserClientLegacy::start: missing entitlement com.apple.appledfr.client

Even resetting the mac PFRAM didn't help. To fix this issue:

1. Connect Android device via USB cable(double USB-C cable worked for me).

2. Go to Settings -> .. -> Developer Options and click Revoke USB debugging authorizations

3. The Android phone will go for a reboot.

4. Go to Settings -> .. -> Developer Options and make sure USB debugging is enabled.

5. Now in macOS terminal enter:

   adb devices
   

6. You can see your device listed.

It worked for my Google Pixel 2 phone.

A short solution is this (PHP 5.3+):

$output['alternate_title'] = $output['alternate_title'] ?:'';

You get either the value of the variable, if it doesn't evaluate to false, or the false expression. (The one after the ':')

Using the ternary Operator, without the "if true" parameter, will return the result of the test expression (The first one ) Since undefined evaluates to false, the false expression will be returned.

In PHP 7 there is the slightly more elegant Null coalescing operator:

$output['alternate_title'] = $output['alternate_title'] ?? '';

(It would be nice with a default assignment operator like '?=')

This exception is probably caused by optimistic locking (or by a bug in your code). You're probably using it without knowing. And your pseudo-code (which should be replaced by real code to be able to diagnose the problem) is wrong. Hibernate saves all the modifications done to attached entities automatically. You shouldn't ever call update, merge or saveOrUpdate on an attached entity. Just do

Email email = session.get(emailId);
email.setSubject(subject);

No need to call update. Hibernate will flush the changes automatically before committing the transaction.
