Haven't tested it, but that should alert the blobs data url:

var blob = event.clipboardData.items[0].getAsFile(), 
    form = new FormData(),
    request = new XMLHttpRequest();

var reader = new FileReader();
reader.onload = function(event) {
  alert(event.target.result); // <-- data url
};
reader.readAsDataURL(blob);

I think the easiest way to return a row with the maximum value is by getting its index. argmax() can be used to return the index of the row with the largest value.

index = df.Value.argmax()

Now the index could be used to get the features for that particular row:

df.iloc[df.Value.argmax(), 0:2]

Updated for swift 3:

// function defination:

@IBAction func showAlertDialog(_ sender: UIButton) {
        // Declare Alert
        let dialogMessage = UIAlertController(title: "Confirm", message: "Are you sure you want to Logout?", preferredStyle: .alert)

        // Create OK button with action handler
        let ok = UIAlertAction(title: "OK", style: .default, handler: { (action) -> Void in
             print("Ok button click...")
             self.logoutFun()
        })

        // Create Cancel button with action handlder
        let cancel = UIAlertAction(title: "Cancel", style: .cancel) { (action) -> Void in
            print("Cancel button click...")
        }

        //Add OK and Cancel button to dialog message
        dialogMessage.addAction(ok)
        dialogMessage.addAction(cancel)

        // Present dialog message to user
        self.present(dialogMessage, animated: true, completion: nil)
    }

// logoutFun() function definaiton :

func logoutFun()
{
    print("Logout Successfully...!")
}

In short, they are equivalent. Let's have a history view:

(1) at first, the function looks like this.

    class MySubClass(MySuperClass):
        def __init__(self):
            MySuperClass.__init__(self)

(2) to make code more abstract (and more portable). A common method to get Super-Class is invented like:

    super(<class>, <instance>)

And init function can be:

    class MySubClassBetter(MySuperClass):
        def __init__(self):
            super(MySubClassBetter, self).__init__()

However requiring an explicit passing of both the class and instance break the DRY (Don't Repeat Yourself) rule a bit.

(3) in V3. It is more smart,

    super()

is enough in most case. You can refer to http://www.python.org/dev/peps/pep-3135/

I got the very easy solution for this - setting different width for column in style sheet by overriding the both cell and header cell:

Example - setting custom width for 1st and 5th column:

.mat-cell:nth-child(1),
.mat-header-cell:nth-child(1) {
  flex: 0 0 5%;
}
.mat-cell:nth-child(5),
.mat-header-cell:nth-child(5) {
  flex: 0 0 10%;
}

Maybe you can get the files (gems) from the gems directory?

gemsdir = "gems directory"
gems = Dir.new(gemsdir).entries

Have a look at the jai (-> mirror) (javascript audio interface) site. From looking at their source, they appear to be calling play() repeatedly, and they mention that their library might be appropriate for use in HTML5-based games.

You can fire multiple audio events simultaneously, which could be used for creating Javascript games, or having a voice speaking over some background music

As Selman22 said, you are overriding the default object.Equals method, which accepts an object obj and not a safe compile time type.

In order for that to happen, make your type implement IEquatable<Box>:

public class Box : IEquatable<Box>
{
    double height, length, breadth;

    public static bool operator ==(Box obj1, Box obj2)
    {
        if (ReferenceEquals(obj1, obj2))
        {
            return true;
        }
        if (ReferenceEquals(obj1, null))
        {
            return false;
        }
        if (ReferenceEquals(obj2, null))
        {
            return false;
        }

        return obj1.Equals(obj2);
    }

    public static bool operator !=(Box obj1, Box obj2)
    {
        return !(obj1 == obj2);
    }

    public bool Equals(Box other)
    {
        if (ReferenceEquals(other, null))
        {
            return false;
        }
        if (ReferenceEquals(this, other))
        {
            return true;
        }

        return height.Equals(other.height) 
               && length.Equals(other.length) 
               && breadth.Equals(other.breadth);
    }

    public override bool Equals(object obj)
    {
        return Equals(obj as Box);
    }

    public override int GetHashCode()
    {
        unchecked
        {
            int hashCode = height.GetHashCode();
            hashCode = (hashCode * 397) ^ length.GetHashCode();
            hashCode = (hashCode * 397) ^ breadth.GetHashCode();
            return hashCode;
        }
    }
}

Another thing to note is that you are making a floating point comparison using the equality operator and you might experience a loss of precision.

For me this happened when I updated Python 64 bit from 3.6.4 to 3.6.5. It threw some error like "unable to extract python.dll. Do you have permissions."

Pycharm also failed to load interpreter, even though I reloaded it in settings. Running python command gave same error, with and without administrator mode.

Reason

There was error in installation of Python, include folder in python installation directory C:\Users\USERNAME\AppData\Local\Programs\Python\Python36 was missing

Reinstalling Python also dint solve the issue.(Not removal and install)

Solution

Uninstall Python and Install of Python again.

Because running installer was just extracting same files excluding include folder

Nested fragments are not currently supported. Trying to put a fragment within the UI of another fragment will result in undefined and likely broken behavior.

Update: Nested fragments are supported as of Android 4.2 (and Android Support Library rev 11) : http://developer.android.com/about/versions/android-4.2.html#NestedFragments

NOTE (as per this docs): "Note: You cannot inflate a layout into a fragment when that layout includes a <fragment>. Nested fragments are only supported when added to a fragment dynamically."

If you are certain that you only need column A, then you can use an End function in VBA to get that result.

If all the cells A1:A100 are filled, then to select the next empty cell use:

Range("A1").End(xlDown).Offset(1, 0).Select

Here, End(xlDown) is the equivalent of selecting A1 and pressing Ctrl + Down Arrow.

If there are blank cells in A1:A100, then you need to start at the bottom and work your way up. You can do this by combining the use of Rows.Count and End(xlUp), like so:

Cells(Rows.Count, 1).End(xlUp).Offset(1, 0).Select

Going on even further, this can be generalized to selecting a range of cells, starting at a point of your choice (not just in column A). In the following code, assume you have values in cells C10:C100, with blank cells interspersed in between. You wish to select all the cells C10:C100, not knowing that the column ends at row 100, starting by manually selecting C10.

Range(Selection, Cells(Rows.Count, Selection.Column).End(xlUp)).Select

The above line is perhaps one of the more important lines to know as a VBA programmer, as it allows you to dynamically select ranges based on very few criteria, and not be bothered with blank cells in the middle.

• Context represents a handle to get environment data .
• Context class itself is declared as abstract, whose implementation is provided by the android OS.
• Context is like remote of a TV & channel's in the television are resources, services, etc.

What can you do with it ?

• Loading resource.
• Launching a new activity.
• Creating views.
• Obtaining system service.

Ways to get context :

• getApplicationContext()
• getContext()
• getBaseContext()

I don't suggest you just hidding the stricts errors on your project. Intead, you should turn your method to static or try to creat a new instance of the object:

$var = new YourClass();
$var->method();

You can also use the new way to do the same since PHP 5.4:

(new YourClass)->method();

I hope it helps you!

I was going through same issue in React-Native where API response & reject weren't updating states

apiCall().then(function(resp) { this.setState({data: resp}) // wasn't updating }

I solved the problem by changing function with the arrow function

apiCall().then((resp) => {
    this.setState({data: resp}) // rendering the view as expected
}

For me, it was a binding issue. Using arrow functions solved it because arrow function doesn't create its's own this, its always bounded to its outer context where it comes from

Another example to output date and time using zero as a fill character on instances of single digit values: 2017-06-04 18:13:02

#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <ctime>
using namespace std;

int main()
{
    time_t t = time(0);   // Get time now
    struct tm * now = localtime(&t);
    cout.fill('0');
    cout << (now->tm_year + 1900) << '-'
        << setw(2) << (now->tm_mon + 1) << '-'
        << setw(2) << now->tm_mday << ' '
        << setw(2) << now->tm_hour << ':'
        << setw(2) << now->tm_min << ':'
        << setw(2) << now->tm_sec
        << endl;
    return 0;
}

Use a "Here-String" and cast to XML.

[xml]$myxml = @"
<stuff>
 <item name="Joe" age="32">
  <info>something about him</info>
 </item>
 <item name="Sue" age="29">
  <info>something about her</info>
 </item>
 <item name="Cat" age="12">
  <info>something else</info>
 </item>
</stuff>
"@

[array]$myitems = $myxml.stuff.Item

$myitems

You can use many ports together for each project,

  php artisan serve --port=8000

  php artisan serve --port=8001   

  php artisan serve --port=8002

  php artisan serve --port=8003

If you want a dictionary you can import from a file by name, and also that adds entries that are nicely sorted, and contains strings you want to preserve, you can try this:

data = {'A': 'a', 'B': 'b', }

with open('file.py','w') as file:
    file.write("dictionary_name = { \n")
    for k in sorted (data.keys()):
        file.write("'%s':'%s', \n" % (k, data[k]))
    file.write("}")

Then to import:

from file import dictionary_name

class App():
    def __init__(self):
        self.root = Tkinter.Tk()
        button = Tkinter.Button(self.root, text = 'root quit', command=self.quit)
        button.pack()
        self.root.mainloop()

    def quit(self):
        self.root.destroy()

app = App()

in.next() will return space-delimited strings. Use in.nextLine() if you want to read the whole line. After reading the string, use question = question.replaceAll("\\s","") to remove spaces.

As said on most of the previous comments, the solution is to add

<item name="colorControlNormal">@color/white</item> to your app theme. But confirm that you don´t have another theme defined in your Toolbar element on your layout.

     <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            android:elevation="4dp"
            android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

The problem is that you're (probably) trying to plot a vector that consists exclusively of missing (NA) values. Here's an example:

> x=rep(NA,100)
> y=rnorm(100)
> plot(x,y)
Error in plot.window(...) : need finite 'xlim' values
In addition: Warning messages:
1: In min(x) : no non-missing arguments to min; returning Inf
2: In max(x) : no non-missing arguments to max; returning -Inf

In your example this means that in your line plot(costs,pseudor2,type="l"), costs is completely NA. You have to figure out why this is, but that's the explanation of your error.

From comments:

Scott C Wilson: Another possible cause of this message (not in this case, but in others) is attempting to use character values as X or Y data. You can use the class function to check your x and Y values to be sure if you think this might be your issue.

stevec: Here is a quick and easy solution to that problem (basically wrap x in as.factor(x))

No. Standard CSS does not provide the kind of thing you're looking for.

However, you might want to look into LESS and SASS.

These are two projects which aim to extend default CSS syntax by introducing additional features, including variables, nested rules, and other enhancements.

They allow you to write much more structured CSS code, and either of them will almost certainly solve your particular use case.

Of course, none of the browsers support their extended syntax (especially since the two projects each have different syntax and features), but what they do is provide a "compiler" which converts your LESS or SASS code into standard CSS, which you can then deploy on your site.

Images have display: inline by default.
You might want to put the image inside the paragraph.
<p><img /></p>

This is surely an encoding problem. You have a different encoding in your database and in your website and this fact is the cause of the problem. Also if you ran that command you have to change the records that are already in your tables to convert those character in UTF-8.

Update: Based on your last comment, the core of the problem is that you have a database and a data source (the CSV file) which use different encoding. Hence you can convert your database in UTF-8 or, at least, when you get the data that are in the CSV, you have to convert them from UTF-8 to latin1.

You can do the convertion following this articles:

• Convert latin1 to UTF8
• http://wordpress.org/support/topic/convert-latin1-to-utf-8

Solution of unchecking comment at first column is partially working, because it works for line comments, but not block comments.

So, with lines like:

/* first line
 * second line
 * ...
 */

or

// line 1
// line 2
// line 3
...

they are indented with "Auto reformat", but lines like:

/* first line
   second line
   ...
 */

the identation will not be fixed.

So you should:

• add * or // before each line of comments
• then uncheck Keep when reformatting -> comment at first column
• and Auto reformat.

Here's the MSDN page describing the flags and what is the result of their various combinations.

Flag combinations => Propagation results
=========================================
No Flags => Target folder.
ObjectInherit => Target folder, child object (file), grandchild object (file).
ObjectInherit and NoPropagateInherit => Target folder, child object (file).
ObjectInherit and InheritOnly => Child object (file), grandchild object (file).
ObjectInherit, InheritOnly, and NoPropagateInherit => Child object (file).
ContainerInherit => Target folder, child folder, grandchild folder.
ContainerInherit, and NoPropagateInherit => Target folder, child folder.
ContainerInherit, and InheritOnly => Child folder, grandchild folder.
ContainerInherit, InheritOnly, and NoPropagateInherit => Child folder.
ContainerInherit, and ObjectInherit => Target folder, child folder, child object (file), grandchild folder, grandchild object (file).
ContainerInherit, ObjectInherit, and NoPropagateInherit => Target folder, child folder, child object (file).
ContainerInherit, ObjectInherit, and InheritOnly => Child folder, child object (file), grandchild folder, grandchild object (file).
ContainerInherit, ObjectInherit, NoPropagateInherit, InheritOnly => Child folder, child object (file).

To have it apply the permissions to the directory, as well as all child directories and files recursively, you'll want to use these flags:

InheritanceFlags.ContainerInherit | InheritanceFlags.ObjectInherit 
PropagationFlags.None

So the specific code change you need to make for your example is:

$PropagationFlag = [System.Security.AccessControl.PropagationFlags]::None

One of the disadvantages of using HTML for labels is when you need to write a localizable program (which should work in several languages). You will have issues to change just the translatable text. Or you will have to put the whole HTML code into your translations which is very awkward, I would even say absurd :)

gui_en.properties:

title.text=<html>Text color: <font color='red'>red</font></html>

gui_fr.properties:

title.text=<html>Couleur du texte: <font color='red'>rouge</font></html>

gui_ru.properties:

title.text=<html>???? ??????: <font color='red'>???????</font></html>

To copy all files, including hidden files use:

cp -r /home/server/folder/test/. /home/server/

After few hours of searching, I just solved this issue with a few lines of code

Your model

      [Required(ErrorMessage = "Enter the issued date.")]
      [DataType(DataType.Date)]
      public DateTime IssueDate { get; set; }

Razor Page

     @Html.TextBoxFor(model => model.IssueDate)
     @Html.ValidationMessageFor(model => model.IssueDate)

Jquery DatePicker

<script type="text/javascript">
    $(document).ready(function () {
        $('#IssueDate').datepicker({
            dateFormat: "dd/mm/yy",
            showStatus: true,
            showWeeks: true,
            currentText: 'Now',
            autoSize: true,
            gotoCurrent: true,
            showAnim: 'blind',
            highlightWeek: true
        });
    });
</script>

Webconfig File

    <system.web>
        <globalization uiCulture="en" culture="en-GB"/>
    </system.web>

Now your text-box will accept "dd/MM/yyyy" format.

Use attribute binding syntax instead

<ol class="viewer-nav"><li *ngFor="let section of sections" 
    [attr.data-sectionvalue]="section.value">{{ section.text }}</li>  
</ol>

or

<ol class="viewer-nav"><li *ngFor="let section of sections" 
    attr.data-sectionvalue="{{section.value}}">{{ section.text }}</li>  
</ol>

In short, the answer is no. Once you show an alert, confirm, or prompt the script no longer has control until the user returns control by clicking one of the buttons.

To do what you want, you will want to use DOM elements like a div and show, then hide it after a specified time. If you need to be modal (takes over the page, allowing no further action) you will have to do additional work.

You could of course use one of the many "dialog" libraries out there. One that comes to mind right away is the jQuery UI Dialog widget

DateTime.Now.ToString("yyyyMMddHHmmss"); // case sensitive

I'm not sure it can be done purely with CSS, unless you're comfortable in sort of faking it with illusions. Maybe use Josh Mein's answer, and set #container to overflow:hidden.

For what it's worth, here's a jQuery solution:

var contH = $('#container').height(),
upH = $('#up').height();
$('#down').css('height' , contH - upH);

late in the game , but this worked for me:

$("#container>table>tbody>tr:first").trigger('click');

What just hit me, coming from Ruby, is that a so-called class method and a so-called instance method is just a function with semantic meaning applied to its first parameter, which is silently passed when the function is called as a method of an object (i.e. obj.meth()).

Normally that object must be an instance but the @classmethod method decorator changes the rules to pass a class. You can call a class method on an instance (it's just a function) - the first argument will be its class.

Because it's just a function, it can only be declared once in any given scope (i.e. class definition). If follows therefore, as a surprise to a Rubyist, that you can't have a class method and an instance method with the same name.

Consider this:

class Foo():
  def foo(x):
    print(x)

You can call foo on an instance

Foo().foo()
<__main__.Foo instance at 0x7f4dd3e3bc20>

But not on a class:

Foo.foo()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unbound method foo() must be called with Foo instance as first argument (got nothing instead)

Now add @classmethod:

class Foo():
  @classmethod
  def foo(x):
    print(x)

Calling on an instance now passes its class:

Foo().foo()
__main__.Foo

as does calling on a class:

Foo.foo()
__main__.Foo

It's only convention that dictates that we use self for that first argument on an instance method and cls on a class method. I used neither here to illustrate that it's just an argument. In Ruby, self is a keyword.

Contrast with Ruby:

class Foo
  def foo()
    puts "instance method #{self}"
  end
  def self.foo()
    puts "class method #{self}"
  end
end

Foo.foo()
class method Foo

Foo.new.foo()
instance method #<Foo:0x000000020fe018>

The Python class method is just a decorated function and you can use the same techniques to create your own decorators. A decorated method wraps the real method (in the case of @classmethod it passes the additional class argument). The underlying method is still there, hidden but still accessible.

footnote: I wrote this after a name clash between a class and instance method piqued my curiosity. I am far from a Python expert and would like comments if any of this is wrong.

It somewhat depends on what you use as a CGI framework, but they are available in dictionaries accessible to the program. I'd point you to the docs, but I'm not getting through to python.org right now. But this note on mail.python.org will give you a first pointer. Look at the CGI and URLLIB Python libs for more.

Update

Okay, that link busted. Here's the basic wsgi ref

This is a slight variation, but PJW's solution didn't quite work for me:

java -version 2>&1 | head -n 1 | cut -d'"' -f2

just cut the string on the delimiter " (double quotes) and get the second field.

On iOS 10 it is possible to add an event listener to the touchmove event and to detect, if the page is zoomed with the current event.

var prevZoomFactorX;_x000D_
var prevZoomFactorY;_x000D_
element.addEventListener("touchmove", (ev) => {_x000D_
  let zoomFactorX = document.documentElement.clientWidth / window.innerWidth;_x000D_
  let zoomFactorY = document.documentElement.clientHeight / window.innerHeight;_x000D_
  let pageHasZoom = !(zoomFactorX === 1 && zoomFactorY === 1);_x000D_
_x000D_
  if(pageHasZoom) {_x000D_
    // page is zoomed_x000D_
    _x000D_
    if(zoomFactorX !== prevZoomFactorX || zoomFactorY !== prevZoomFactorY) {_x000D_
      // page is zoomed with this event_x000D_
    }_x000D_
  }_x000D_
  prevZoomFactorX = zoomFactorX;_x000D_
  prevZoomFactorY = zoomFactorY;_x000D_
});

Presuming that you have installed: bash, pwd, dirname, echo; then relpath is

#!/bin/bash
s=$(cd ${1%%/};pwd); d=$(cd $2;pwd); b=; while [ "${d#$s/}" == "${d}" ]
do s=$(dirname $s);b="../${b}"; done; echo ${b}${d#$s/}

I've golfed the answer from pini and a few other ideas

Note: This requires both paths to be existing folders. Files will not work.

The memory in memcpy cannot overlap or you risk undefined behaviour, while the memory in memmove can overlap.

char a[16];
char b[16];

memcpy(a,b,16);           // valid
memmove(a,b,16);          // Also valid, but slower than memcpy.
memcpy(&a[0], &a[1],10);  // Not valid since it overlaps.
memmove(&a[0], &a[1],10); // valid. 

Some implementations of memcpy might still work for overlapping inputs but you cannot count of that behaviour. While memmove must allow for overlapping.

The length of the url can't be changed in PHP. The linked question is about the URL size limit, you will find what you want.

To prevent the problem from occurring, you must perform a graceful shutdown of the server from the command line rather than powering off the server.

# shutdown -h now

This will stop the running services before powering down the machine.

Based on Centos, an additional method for getting it back up again when you run into this problem is to move mysql.sock:

# mv /var/lib/mysql/mysql.sock /var/lib/mysql/mysql.sock.bak

# service mysqld start

Restarting the service creates a new entry called mqsql.sock

// Initialize these to the smallest value possible
int highest = Integer.MIN_VALUE;
int secondHighest = Integer.MIN_VALUE;

// Loop over the array
for (int i = 0; i < array.Length; i++) {

    // If we've found a new highest number...
    if (array[i] > highest) {

        // ...shift the current highest number to second highest
        secondHighest = highest;

        // ...and set the new highest.
        highest = array[i];
    } else if (array[i] > secondHighest)
        // Just replace the second highest
        secondHighest = array[i];
    }
}

// After exiting the loop, secondHighest now represents the second
// largest value in the array

Edit:

JFrame.dispose()

public void dispose()

Releases all of the native screen resources used by this Window, its subcomponents, and all of its owned children. That is, the resources for these Components will be destroyed, any memory they consume will be returned to the OS, and they will be marked as undisplayable. The Window and its subcomponents can be made displayable again by rebuilding the native resources with a subsequent call to pack or show. The states of the recreated Window and its subcomponents will be identical to the states of these objects at the point where the Window was disposed (not accounting for additional modifications between those actions).

Note: When the last displayable window within the Java virtual machine (VM) is disposed of, the VM may terminate. See AWT Threading Issues for more information.

System.exit()

public static void exit(int status)

Terminates the currently running Java Virtual Machine. The argument serves as a status code; by convention, a nonzero status code indicates abnormal termination. This method calls the exit method in class Runtime. This method never returns normally.

The call System.exit(n) is effectively equivalent to the call:

Runtime.getRuntime().exit(n)

You should change/add in your PostController: (and change PostsController to PostController)

public function create()
{
    $categories = Category::all();
    return view('create',compact('categories'));
}

public function store(Request $request)
{
    $post = new Posts;
    $post->title = $request->get('title'); // CHANGE THIS
    $post->body = $request->get('body'); // CHANGE THIS
    $post->save(); // ADD THIS
    $post->categories()->attach($request->get('categories_id')); // CHANGE THIS

    return redirect()->route('posts.index'); // PS ON THIS ONE
}

PS: using route() means you have named your route as such

Route::get('example', 'ExampleController@getExample')->name('getExample');

UPDATE

The comments above are also right, change your 'Posts' Model to 'Post'

Try the SVG2VectorDrawable Plugin. Go to Preferences->Plugins->Browse Plugins and install SVG2VectorDrawable. Great for converting sag files to vector drawable. Once you have installed you will find an icon for this in the toolbar section just to the right of the help (?) icon.

I assume from db that this is LINQ-to-SQL / Entity Framework / similar (not LINQ-to-Objects);

Generally, you do better with the conditional syntax ( a ? b : c) - however, I don't know if it will work with your different queries like that (after all, how would your write the TSQL?).

For a trivial example of the type of thing you can do:

select new {p.PriceID, Type = p.Price > 0 ? "debit" : "credit" };

You can do much richer things, but I really doubt you can pick the table in the conditional. You're welcome to try, of course...

I got the same issue and this solved it for me. Perhaps this might be a fix for your problem too.

Here is the fix. Follow this link http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/

Go to "Fixed curl extensions" and download the extension that matches your PHP version.

Extract and copy "php_curl.dll" to the extension directory of your wamp installation. (i.e. C:\wamp\bin\php\php5.3.13\ext)

Restart Apache

Done!

Refer to: http://blog.nterms.com/2012/07/php-curl-issues-with-wamp-server-on.html

Cheers!

Like @endeR mentioned, if internationalization is a concern, the unicode_utils gem is more than adequate.

$ gem install unicode_utils
$ irb
> require 'unicode_utils'
=> true
> UnicodeUtils.downcase("FEN BILIMLERI", :tr)
=> "fen bilimleri"

String manipulations in Ruby 2.4 are now unicode-sensitive.

Since this page is the number 1 result for the google search "c++ floating point exception", I want to add another thing that can cause such a problem: use of undefined variables.

use the pattern

<input 
       type="number" 
       name="price"
       pattern="[0-9]+([\.,][0-9]+)?" 
       step="0.01"
       title="This should be a number with up to 2 decimal places."

good luck

One correct answer is:

/a/b/*[self::c or self::d or self::e]

Do note that this

a/b/*[local-name()='c' or local-name()='d' or local-name()='e']

is both too-long and incorrect. This XPath expression will select nodes like:

OhMy:c

NotWanted:d 

QuiteDifferent:e

You can use REINDEX to do that.

Reindex does not attempt to set up the destination index. It does not copy the settings of the source index. You should set up the destination index prior to running a _reindex action, including setting up mappings, shard counts, replicas, etc.

1. First copy the index to a new name

POST /_reindex
{
  "source": {
    "index": "twitter"
  },
  "dest": {
    "index": "new_twitter"
  }
}

2. Now delete the Index

DELETE /twitter

If you are using Count, or have created your own Count-style dict and want to show the name of the item and the count of it, you can iterate around the dictionary like so:

top_10_words = Counter(my_long_list_of_words)
# Iterate around the dictionary
for word in top_10_words:
        # print the word
        print word[0]
        # print the count
        print word[1]

or to iterate through this in a template:

{% for word in top_10_words %}
        <p>Word: {{ word.0 }}</p>
        <p>Count: {{ word.1 }}</p>
{% endfor %}

Hope this helps someone

As mentioned by Bunkar typeid(T).name is implementation defined.

To avoid this issue you can use Boost.TypeIndex library.

For example:

boost::typeindex::type_id<T>().pretty_name() // human readable

var iDiv = document.createElement('div'),
    jDiv = document.createElement('div');
iDiv.id = 'block';
iDiv.className = 'block';
jDiv.className = 'block-2';
iDiv.appendChild(jDiv);
document.getElementsByTagName('body')[0].appendChild(iDiv);

Take a look at the .classpath file in your project, which probably contains most of the information that you want. The easiest option may be to roll your own "build.xml export", i.e. process .classpath into a new build.xml during the build itself, and then call it with an ant subtask.

Parsing a little XML sounds much easier to me than to hook into Eclipse JDT.

You can add your own id or class to the body tag of your index page to target all elements on that page with a custom style like so:

<body id="index">
   <h1>...</h1>
</body>

Then you can target the elements you wish to modify with your class or id like so:

#index h1 {
   color:red;
}

Natural Number (Strings) Quick Sort

Just to pile onto the topic. Normally, if you sort strings with numbers you'll get something like this:

    Text1
    Text10
    Text100
    Text11
    Text2
    Text20

But you really want it to recognize the numerical values and be sorted like

    Text1
    Text2
    Text10
    Text11
    Text20
    Text100

Here's how to do it...

Note:

• I stole the Quick Sort from the internet a long time ago, not sure where now...
• I translated the CompareNaturalNum function which was originally written in C from the internet as well.
• Difference from other Q-Sorts: I don't swap the values if the BottomTemp = TopTemp

Natural Number Quick Sort

Public Sub QuickSortNaturalNum(strArray() As String, intBottom As Integer, intTop As Integer)
Dim strPivot As String, strTemp As String
Dim intBottomTemp As Integer, intTopTemp As Integer

    intBottomTemp = intBottom
    intTopTemp = intTop

    strPivot = strArray((intBottom + intTop) \ 2)

    Do While (intBottomTemp <= intTopTemp)
        ' < comparison of the values is a descending sort
        Do While (CompareNaturalNum(strArray(intBottomTemp), strPivot) < 0 And intBottomTemp < intTop)
            intBottomTemp = intBottomTemp + 1
        Loop
        Do While (CompareNaturalNum(strPivot, strArray(intTopTemp)) < 0 And intTopTemp > intBottom) '
            intTopTemp = intTopTemp - 1
        Loop
        If intBottomTemp < intTopTemp Then
            strTemp = strArray(intBottomTemp)
            strArray(intBottomTemp) = strArray(intTopTemp)
            strArray(intTopTemp) = strTemp
        End If
        If intBottomTemp <= intTopTemp Then
            intBottomTemp = intBottomTemp + 1
            intTopTemp = intTopTemp - 1
        End If
    Loop

    'the function calls itself until everything is in good order
    If (intBottom < intTopTemp) Then QuickSortNaturalNum strArray, intBottom, intTopTemp
    If (intBottomTemp < intTop) Then QuickSortNaturalNum strArray, intBottomTemp, intTop
End Sub

To remove all columns after the one you want, below code should work. It will remove at index 10 (remember Columns are 0 based), until the Column count is 10 or less.

DataTable dt;
int desiredSize = 10;

while (dt.Columns.Count > desiredSize)
{
   dt.Columns.RemoveAt(desiredSize);
}

You need to merge the remote branch into your current branch by running git pull.

If your local branch is already up-to-date, you may also need to run git pull --rebase.

A quick google search also turned up this same question asked by another SO user: Cannot push to GitHub - keeps saying need merge. More details there.

This is how I do it in case anyone in the future is wondering.

I put this in the .htaccess file on the root server:

RewriteEngine on 
RewriteCond %{HTTP_REFERER} !^http://(www\.)?domain.com/ [NC] 
RewriteCond %{HTTP_REFERER} !^http://(www\.)?domain.com.*$ [NC]
RewriteRule \.(mp4|avi)$ - [F]

This stops them from say going to domain.com/videos/myVid.mp4 and then saving it from there.

Depending on your platform you can use: sqlite3 file_name.db from the terminal. .tables will list the tables, .schema is full layout. SQLite commands like: select * from table_name; and such will print out the full contents. Type: ".exit" to exit. No need to download a GUI application.Use a semi-colon if you want it to execute a single command. Decent SQLite usage tutorial http://www.thegeekstuff.com/2012/09/sqlite-command-examples/

If you want to do that why not go with a while, for ease of mind? :P No, but seriously I didn't know that and seems kinda nice so thanks, nice to know!

During a job interview of mine, the company CTO who was interviewing me tried out a word/web game I wrote in Java. Out of a word list of the entire Oxford English dictionary, what was the first word that came up to be guessed?

Of course, the most foul word in the English language.

Somehow, I still got the job offer, but I then tracked down a profanity word list (not unlike this one) and wrote a quick script to generate a new dictionary without all of the bad words (without even having to look at the list).

For your particular case, I think comparing the search to real words sounds like the way to go with a word list like that. The alternative styles/punctuation require a bit more work, but I doubt users will use that often enough to be an issue.

This answer has been updated to Swift 3

I always think it is nice to have a very simple, self-contained example so that nothing is assumed when I am learning a new task. This answer is that for deleting UITableView rows. The project performs like this:

This project is based on the UITableView example for Swift.

Add the Code

Create a new project and replace the ViewController.swift code with the following.

import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {

    // These strings will be the data for the table view cells
    var animals: [String] = ["Horse", "Cow", "Camel", "Pig", "Sheep", "Goat"]

    let cellReuseIdentifier = "cell"

    @IBOutlet var tableView: UITableView!

    override func viewDidLoad() {
        super.viewDidLoad()

        // It is possible to do the following three things in the Interface Builder
        // rather than in code if you prefer.
        self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: cellReuseIdentifier)
        tableView.delegate = self
        tableView.dataSource = self
    }

    // number of rows in table view
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return self.animals.count
    }

    // create a cell for each table view row
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        let cell:UITableViewCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as UITableViewCell!

        cell.textLabel?.text = self.animals[indexPath.row]

        return cell
    }

    // method to run when table view cell is tapped
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        print("You tapped cell number \(indexPath.row).")
    }

    // this method handles row deletion
    func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {

        if editingStyle == .delete {

            // remove the item from the data model
            animals.remove(at: indexPath.row)

            // delete the table view row
            tableView.deleteRows(at: [indexPath], with: .fade)

        } else if editingStyle == .insert {
            // Not used in our example, but if you were adding a new row, this is where you would do it.
        }
    }

}

The single key method in the code above that enables row deletion is the last one. Here it is again for emphasis:

// this method handles row deletion
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {

    if editingStyle == .delete {

        // remove the item from the data model
        animals.remove(at: indexPath.row)

        // delete the table view row
        tableView.deleteRows(at: [indexPath], with: .fade)

    } else if editingStyle == .insert {
        // Not used in our example, but if you were adding a new row, this is where you would do it.
    }
}

Storyboard

Add a UITableView to the View Controller in the storyboard. Use auto layout to pin the four sides of the table view to the edges of the View Controller. Control drag from the table view in the storyboard to the @IBOutlet var tableView: UITableView! line in the code.

Finished

That's all. You should be able to run your app now and delete rows by swiping left and tapping "Delete".

Variations

Change the "Delete" button text

Add the following method:

func tableView(_ tableView: UITableView, titleForDeleteConfirmationButtonForRowAt indexPath: IndexPath) -> String? {
    return "Erase"
}

Custom button actions

Add the following method.

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {

    // action one
    let editAction = UITableViewRowAction(style: .default, title: "Edit", handler: { (action, indexPath) in
        print("Edit tapped")
    })
    editAction.backgroundColor = UIColor.blue

    // action two
    let deleteAction = UITableViewRowAction(style: .default, title: "Delete", handler: { (action, indexPath) in
        print("Delete tapped")
    })
    deleteAction.backgroundColor = UIColor.red

    return [editAction, deleteAction]
}

Note that this is only available from iOS 8. See this answer for more details.

Updated for iOS 11

Actions can be placed either leading or trailing the cell using methods added to the UITableViewDelegate API in iOS 11.

func tableView(_ tableView: UITableView,
                leadingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?
 {
     let editAction = UIContextualAction(style: .normal, title:  "Edit", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
             success(true)
         })
editAction.backgroundColor = .blue

         return UISwipeActionsConfiguration(actions: [editAction])
 }

 func tableView(_ tableView: UITableView,
                trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration?
 {
     let deleteAction = UIContextualAction(style: .normal, title:  "Delete", handler: { (ac:UIContextualAction, view:UIView, success:(Bool) -> Void) in
         success(true)
     })
     deleteAction.backgroundColor = .red

     return UISwipeActionsConfiguration(actions: [deleteAction])
 }

You get an apparently random set because ROWNUM is applied before the ORDER BY. So your query takes the first ten rows and sorts them.0 To select the top ten salaries you should use an analytic function in a subquery, then filter that:

 select * from 
     (select empno,
             ename,
             sal,
             row_number() over(order by sal desc nulls last) rnm
    from emp) 
 where rnm<=10

Create a new table called comments

They should have a column containing the id of the post they are assigned to.

Make a form which adds a new comment to that table.

An example (not tested so may contain lil' syntax errors): I call a page with comments a post

Post.php

<!-- Post content here -->

<!-- Then cmments below -->
<h1>Comments</h1>
<?php
$result = mysql_query("SELECT * FROM comments WHERE postid=0");
//0 should be the current post's id
while($row = mysql_fetch_object($result))
{
?>
<div class="comment">
By: <?php echo $row->author; //Or similar in your table ?>
<p>
<?php echo;$row->body; ?>
</p>
</div>
<?php
}
?>
<h1>Leave a comment:</h1>
<form action="insertcomment.php" method="post">

You must change the code a bit to make it work. I'n not doing your homework. Only a part of it ;)

the htons() function converts values between host and network byte orders. There is a difference between big-endian and little-endian and network byte order depending on your machine and network protocol in use.

You can define your own custom MarshalJSON and UnmarshalJSON methods and intentionally control what should be included, ex:

package main

import (
    "fmt"
    "encoding/json"
)

type User struct {
    name string
}

func (u *User) MarshalJSON() ([]byte, error) {
    return json.Marshal(&struct {
        Name     string `json:"name"`
    }{
        Name:     "customized" + u.name,
    })
}

func main() {
    user := &User{name: "Frank"}
    b, err := json.Marshal(user)
    if err != nil {
        fmt.Println(err)
        return
    }
    fmt.Println(string(b))
}

"Another idea which was suggested by SCdF would be to append a bogus query string to the file. (Some Python code to automatically use the timestamp as a bogus query string was submitted by pi.) However, there is some discussion as to whether or not the browser would cache a file with a query string. (Remember, we want the browser to cache the file and use it on future visits. We only want it to fetch the file again when it has changed.) Since it is not clear what happens with a bogus query string, I am not accepting that answer."

<link rel="stylesheet" href="file.css?<?=hash_hmac('sha1', session_id(), md5_file("file.css")); ?>" />

Hashing the file means when it has changed, the query string will have changed. If it hasn't, it will remain the same. Each session forces a reload too.

Optionally, you can also use rewrites to cause the browser to think it's a new URI.

The str.split method will automatically remove all white space between items:

>>> str1 = "a    b     c      d"
>>> str1.split()
['a', 'b', 'c', 'd']

Docs are here: http://docs.python.org/library/stdtypes.html#str.split

I've fought the HTML email battle before. Here are some of my tips about styling for maximum compatibility between email clients.

• Inline styles are you best friend. Absolutely don't link style sheets and do not use a <style> tag (GMail, for example, strips that tag and all it's contents).

• Against your better judgement, use and abuse tables. <div>s just won't cut it (especially in Outlook).

• Don't use background images, they're spotty and will annoy you.

• Remember that some email clients will automatically transform typed out hyperlinks into links (if you don't anchor <a> them yourself). This can sometimes achieve negative effects (say if you're putting a style on each of the hyperlinks to appear a different color).

• Be careful hyperlinking an actual link with something different. For example, don't type out http://www.google.com and then link it to https://gmail.com/. Some clients will flag the message as Spam or Junk.

• Save your images in as few colors as possible to save on size.

• If possible, embed your images in your email. The email won't have to reach out to an external web server to download them and they won't appear as attachments to the email.

And lastly, test, test, test! Each email client does things way differently than a browser would do.

QTcreator obeys your kde-wide configurations. If you choose "obsidian-coast" as the system-wide color scheme qt creator will be all dark as well. I know it is a partial solution but it works.

db.data.update({'name': 'zero'}, {'$set': {'value': NumberInt(0)}})

You can also use NumberLong.

just change them to password('yourpassword')

ProcessBuilder is very easy to use.

ProcessBuilder pb = new ProcessBuilder("python","Your python file",""+Command line arguments if any);
Process p = pb.start();

This should call python. Refer to the process approach here for full example!

Short but simple explanation:

I the worst case you would need to visit all the vertex and edge hence the time complexity in the worst case is O(V+E)

Look at the ToLookup and/or ToDictionary extension methods.

Piece of cake!

CSV Files with Custom Delimiters

By default, a comma is used as a delimiter in a CSV file. However, some CSV files can use delimiters other than a comma. Few popular ones are | and \t.

import csv
data_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, delimiter='|')
    writer.writerows(data_list)

output:

SN|Name|Contribution
1|Linus Torvalds|Linux Kernel
2|Tim Berners-Lee|World Wide Web
3|Guido van Rossum|Python Programming

Write CSV files with quotes

import csv

row_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, quoting=csv.QUOTE_NONNUMERIC, delimiter=';')
    writer.writerows(row_list) 

output:

"SN";"Name";"Contribution"
1;"Linus Torvalds";"Linux Kernel"
2;"Tim Berners-Lee";"World Wide Web"
3;"Guido van Rossum";"Python Programming"

As you can see, we have passed csv.QUOTE_NONNUMERIC to the quoting parameter. It is a constant defined by the csv module.

csv.QUOTE_NONNUMERIC specifies the writer object that quotes should be added around the non-numeric entries.

There are 3 other predefined constants you can pass to the quoting parameter:

• csv.QUOTE_ALL - Specifies the writer object to write CSV file with quotes around all the entries.
• csv.QUOTE_MINIMAL - Specifies the writer object to only quote those fields which contain special characters (delimiter, quotechar or any characters in lineterminator)
• csv.QUOTE_NONE - Specifies the writer object that none of the entries should be quoted. It is the default value.

import csv

row_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, quoting=csv.QUOTE_NONNUMERIC,
                        delimiter=';', quotechar='*')
    writer.writerows(row_list)

output:

*SN*;*Name*;*Contribution*
1;*Linus Torvalds*;*Linux Kernel*
2;*Tim Berners-Lee*;*World Wide Web*
3;*Guido van Rossum*;*Python Programming*

Here, we can see that quotechar='*' parameter instructs the writer object to use * as quote for all non-numeric values.

Generic Webhook Trigger Plugin can be configured with filters to achieve this.

When configured with

• A variable named ref and expression $.ref.
• A filter with text $ref and filter expression like ^refs/heads/master$.

Then that job will trigger for every push to master. No polling.

You probably want more values from the webhook to actually perform the build. Just add more variables, with JSONPath, to pick what you need.

There are some use cases here: https://github.com/jenkinsci/generic-webhook-trigger-plugin/tree/master/src/test/resources/org/jenkinsci/plugins/gwt/bdd

I don't see the entry on his blog (link pls?) but according to the gnu reference manual:

Enclosing characters in single quotes (‘'’) preserves the literal value of each character within the quotes. A single quote may not occur between single quotes, even when preceded by a backslash.

so bash won't understand:

alias x='y \'z '

however, you can do this if you surround with double quotes:

alias x="echo \'y "
> x
> 'y

USe this function for date comparison in javascript:

    function fn_DateCompare(DateA, DateB) {
      var a = new Date(DateA);
      var b = new Date(DateB);

      var msDateA = Date.UTC(a.getFullYear(), a.getMonth()+1, a.getDate());
      var msDateB = Date.UTC(b.getFullYear(), b.getMonth()+1, b.getDate());

      if (parseFloat(msDateA) < parseFloat(msDateB))
        return -1;  // less than
      else if (parseFloat(msDateA) == parseFloat(msDateB))
        return 0;  // equal
      else if (parseFloat(msDateA) > parseFloat(msDateB))
        return 1;  // greater than
      else
        return null;  // error
  }

You can Try using :- git ls-files -s

String hexToAscii(String s) {
  int n = s.length();
  StringBuilder sb = new StringBuilder(n / 2);
  for (int i = 0; i < n; i += 2) {
    char a = s.charAt(i);
    char b = s.charAt(i + 1);
    sb.append((char) ((hexToInt(a) << 4) | hexToInt(b)));
  }
  return sb.toString();
}

private static int hexToInt(char ch) {
  if ('a' <= ch && ch <= 'f') { return ch - 'a' + 10; }
  if ('A' <= ch && ch <= 'F') { return ch - 'A' + 10; }
  if ('0' <= ch && ch <= '9') { return ch - '0'; }
  throw new IllegalArgumentException(String.valueOf(ch));
}

ls -ltrh /proc | grep YOUR-PID-HERE

For example, my Google Chrome's PID is 11583:

ls -l /proc | grep 11583
dr-xr-xr-x  7 adam       adam                     0 2011-04-20 16:34 11583

1. Like you installed older version of PHP do the same with Apache. I picked version 2.0.63 and then I was able to run WAMP Server with PHP 5.2.9 with no problems.

2. I also read that it's problem with 64-bit version of WAMP.

The application is a server which simply runs until the system shuts down or it receives a Ctrl+C or the console window is closed.

Due to the extraordinary nature of the application, it is not feasible to "gracefully" exit. (It may be that I could code another application which would send a "server shutdown" message but that would be overkill for one application and still insufficient for certain circumstances like when the server (Actual OS) is actually shutting down.)

Because of these circumstances I added a "ConsoleCtrlHandler" where I stop my threads and clean up my COM objects etc...

Public Declare Auto Function SetConsoleCtrlHandler Lib "kernel32.dll" (ByVal Handler As HandlerRoutine, ByVal Add As Boolean) As Boolean

Public Delegate Function HandlerRoutine(ByVal CtrlType As CtrlTypes) As Boolean

Public Enum CtrlTypes
  CTRL_C_EVENT = 0
  CTRL_BREAK_EVENT
  CTRL_CLOSE_EVENT
  CTRL_LOGOFF_EVENT = 5
  CTRL_SHUTDOWN_EVENT
End Enum

Public Function ControlHandler(ByVal ctrlType As CtrlTypes) As Boolean
.
.clean up code here
.
End Function

Public Sub Main()
.
.
.
SetConsoleCtrlHandler(New HandlerRoutine(AddressOf ControlHandler), True)
.
.
End Sub

This setup seems to work out perfectly. Here is a link to some C# code for the same thing.

Short answer:

As written in xsd:

<xs:attribute name="minOccurs" type="xs:nonNegativeInteger" use="optional" default="1"/>
<xs:attribute name="maxOccurs" type="xs:allNNI" use="optional" default="1"/>

If you provide an attribute with number, then the number is boundary. Otherwise attribute should appear exactly once.

After many fruitful hours of exploring OCR libraries, bounding boxes and clustering algorithms - I found a solution so simple it makes you want to cry!

I hope you are using Linux;

pdftotext -layout NAME_OF_PDF.pdf

AMAZING!!

Now you have a nice text file with all the information lined up in nice columns, now it is trivial to format into a csv etc..

It is for times like this that I love Linux, these guys came up with AMAZING solutions to everything, and put it there for FREE!

For me, using EF6 and Visual Studio 2015 I entered query in the immediate window and it gave me the generated SQL Statement

If I understood your problem correctly, it's similar to one I just had. You want to be able limit the usability of DISTINCT to a specified field, rather than applying it to all the data.

If you use GROUP BY without an aggregate function, which ever field you GROUP BY will be your DISTINCT filed.

If you make your query:

SELECT * from table GROUP BY field1;

It will show all your results based on a single instance of field1.

For example, if you have a table with name, address and city. A single person has multiple addresses recorded, but you just want a single address for the person, you can query as follows:

SELECT * FROM persons GROUP BY name;

The result will be that only one instance of that name will appear with its address, and the other one will be omitted from the resulting table. Caution: if your fileds have atomic values such as firstName, lastName you want to group by both.

SELECT * FROM persons GROUP BY lastName, firstName;

because if two people have the same last name and you only group by lastName, one of those persons will be omitted from the results. You need to keep those things into consideration. Hope this helps.

Had this issue at work (running VS2017). Tried all of the answers here. No joy.

The project would build just fine, but was complaining that namespaces / types couldn't be found. Red squiggles all over the place. Lots of errors in the Error List window.

My solution contained 3 projects.

Discovered that 3 of the NuGet library references for one of the projects was out of line. Consolidated the referenced library versions, and Bingo.

Hope this helps someone.

Brett.

There were two conditions that caused the expression ((var++)) to fail for me:

1. If I set bash to strict mode (set -euo pipefail) and if I start my increment at zero (0).

2. Starting at one (1) is fine but zero causes the increment to return "1" when evaluating "++" which is a non-zero return code failure in strict mode.

I can either use ((var+=1)) or var=$((var+1)) to escape this behavior

No formulas required. This works on as many columns as you need, but will only compare columns in the same worksheet:

NOTE: remove any duplicates from the individual columns first!

1. Select the columns to compare
2. click Conditional Formatting
3. click Highlight Cells Rules
4. click Duplicate Values (the defaults should be OK)

5. Duplicates are now highlighted in red

   • Bonus tip, you can filter each row by colour to either leave the unique values in the column, or leave just the duplicates.

Finally I got the solution

sudo ln -s /etc/phpmyadmin/apache.conf /etc/apache2/conf-available/phpmyadmin.conf
sudo a2enconf phpmyadmin
sudo service apache2 reload

More about https://askubuntu.com/questions/55280/phpmyadmin-is-not-working-after-i-installed-it

I had a similar problem with a less complicated formula:

= If (x > A & x <= B) 

and found that I could Remove the AND and join the two comparisons with +

  = (x > A1) + (x <= B1)        [without all the spaces]

Hope this helps others with less complex comparisons.

This worked for me and allow to use an headless browser, you just need to call the method passing your proxy.

def setProxy(proxy):
        options = Options()
        options.headless = True
        #options.add_argument("--window-size=1920,1200")
        options.add_argument("--disable-dev-shm-usage")
        options.add_argument("--no-sandbox")
        prox = Proxy()
        prox.proxy_type = ProxyType.MANUAL
        prox.http_proxy = proxy
        prox.ssl_proxy = proxy
        capabilities = webdriver.DesiredCapabilities.CHROME
        prox.add_to_capabilities(capabilities)
        return webdriver.Chrome(desired_capabilities=capabilities, options=options, executable_path=DRIVER_PATH)

DELETE FROM blob
WHERE NOT EXISTS (
    SELECT *
    FROM files
    WHERE id=blob.id
)

I'm testing on IE, Firefox and Chrome May 2015 and this works best with the current versions. It centers the HR and makes it 70% wide:

hr.light { _x000D_
    width:70%; _x000D_
    margin:0 auto; _x000D_
    border:0px none white; _x000D_
    border-top:1px solid lightgrey; _x000D_
}

<hr class="light" />

You can use upstream headers (named starting with $http_) and additional custom headers. For example:

add_header X-Upstream-01 $http_x_upstream_01;
add_header X-Hdr-01  txt01;

next, go to console and make request with user's header:

curl -H "X-Upstream-01: HEADER1" -I http://localhost:11443/

the response contains X-Hdr-01, seted by server and X-Upstream-01, seted by client:

HTTP/1.1 200 OK
Server: nginx/1.8.0
Date: Mon, 30 Nov 2015 23:54:30 GMT
Content-Type: text/html;charset=UTF-8
Connection: keep-alive
X-Hdr-01: txt01
X-Upstream-01: HEADER1

This example demonstrate the .join() action:

import threading
import time

def threaded_worker():
    for r in range(10):
        print('Other: ', r)
        time.sleep(2)

thread_ = threading.Timer(1, threaded_worker)
thread_.daemon = True  # If the main thread kills, this thread will be killed too. 
thread_.start()

flag = True

for i in range(10):
    print('Main: ', i)
    time.sleep(2)
    if flag and i > 4:
        print(
            '''
            Threaded_worker() joined to the main thread. 
            Now we have a sequential behavior instead of concurrency.
            ''')
        thread_.join()
        flag = False

Out:

Main:  0
Other:  0
Main:  1
Other:  1
Main:  2
Other:  2
Main:  3
Other:  3
Main:  4
Other:  4
Main:  5
Other:  5

            Threaded_worker() joined to the main thread. 
            Now we have a sequential behavior instead of concurrency.

Other:  6
Other:  7
Other:  8
Other:  9
Main:  6
Main:  7
Main:  8
Main:  9

When I edit, rename, and move a file at the same time, none of these solutions work. The solution is to do it in two commits (edit and rename/move seperate) and then fixup the second commit via git rebase -i to have it in one commit.

I found a tool "webchk” written in Python. Returns a status code for a list of urls. https://pypi.org/project/webchk/

Output looks like this:

? webchk -i ./dxieu.txt | grep '200'

Hope that helps!

Here is how to to that:

The header and footer are 30px height.

The footer is stuck to the bottom of the page.

HTML:

<div id="header">
</div>
<div id="content">
</div>
<div id="footer">
</div>

CSS:

#header {
    height: 30px;
}
#footer {
    height: 30px;
    position: absolute;
    bottom: 0;
}
body {
    height: 100%;
    margin-bottom: 30px;
}

Try it on jsfiddle: http://jsfiddle.net/Usbuw/

I don't think that there are any neat tricks you can do storing this as you can do for example with an MD5 hash.

I think your best bet is to store it as a CHAR(60) as it is always 60 chars long

Eaven if you are going to prevent sql injection front-end, using html or js checks, you'd have to consider that front-end checks are "bypassable".

You can disable js or edit a pattern with a front-end development tool (built in with firefox or chrome nowadays).

So, in order to prevent SQL injection, would be right to sanitize input date backend inside your controller.

I would like to suggest to you to use filter_input() native PHP function in order to sanitize GET and INPUT values.

If you want to go ahead with security, for sensible database queries, I'd like to suggest to you to use regular expression to validate data format. preg_match() will help you in this case! But take care! Regex engine is not so light. Use it only if necessary, otherwise your application performances will decrease.

Security has a costs, but do not waste your performance!

Easy example:

if you want to double check if a value, received from GET is a number, less then 99 if(!preg_match('/[0-9]{1,2}/')){...} is heavyer of

if (isset($value) && intval($value)) <99) {...}

So, the final answer is: "No! PDO Prepared Statements does not prevent all kind of sql injection"; It does not prevent unexpected values, just unexpected concatenation

$('title').text();

returns all the title

but if you just want the page title then use

document.title

If your context allows it (technical constraints, etc.), use the JsonConvert.SerializeObject method from Newtonsoft.Json : it will make your life easier.

Dictionary<string, string> localizedWelcomeLabels = new Dictionary<string, string>();
localizedWelcomeLabels.Add("en", "Welcome");
localizedWelcomeLabels.Add("fr", "Bienvenue");
localizedWelcomeLabels.Add("de", "Willkommen");
Console.WriteLine(JsonConvert.SerializeObject(localizedWelcomeLabels));

// Outputs : {"en":"Welcome","fr":"Bienvenue","de":"Willkommen"}

• Use a nonbacktracking expression to match the whole password first, if it has at least 8 characters (this way, there is no combinatorial explosion for long, but invalid passwords): (?>{8,})
• Use lookbehind assertions to check for presence of all required characters (AND-conditions). (?<=...)
• At least one uppercase character: (?<=\p{Lu}.*)
• At least one special character (a bit ambiguous, but let's use not-word): (?<=\W.*)
• At least one alphanumeric character (: (?<=\w.*)

Summed up:

(?>.{8,})(?<=\p{Lu}.*)(?<=\W.*)(?<=\w.*)

You should grab the standard input of the su process just launched and write down the command there, otherwise you are running the commands with the current UID.

Try something like this:

try{
    Process su = Runtime.getRuntime().exec("su");
    DataOutputStream outputStream = new DataOutputStream(su.getOutputStream());

    outputStream.writeBytes("screenrecord --time-limit 10 /sdcard/MyVideo.mp4\n");
    outputStream.flush();

    outputStream.writeBytes("exit\n");
    outputStream.flush();
    su.waitFor();
}catch(IOException e){
    throw new Exception(e);
}catch(InterruptedException e){
    throw new Exception(e);
}

I tried a few ones above but they seem to reset @ 1000

This one definately works, and should also take year into consideration

long millisStart = Calendar.getInstance().getTimeInMillis();

and then do the same for end time if needed.

In Python 3.6:

from datetime import datetime
datetime.now().isoformat(' ', 'seconds')
'2017-01-11 14:41:33'

https://docs.python.org/3.6/library/datetime.html#datetime.datetime.isoformat

mystring = mystring.Length > 4 ? mystring.Substring(mystring.Length - 4, 4) : mystring;

According to the language specification you can use a raw string literal, where the string is delimited by backticks instead of double quotes.

`line 1
line 2
line 3`

This works for me in irb:

irb> (1..4).to_a
=> [1, 2, 3, 4]

I notice that:

irb> 1..4.to_a
(irb):1: warning: default `to_a' will be obsolete
ArgumentError: bad value for range
        from (irb):1

So perhaps you are missing the parentheses?

A general/reusable solution

This answer is provided for future reference to all those that bump into this problem. Solution consists of two things:

1. Custom exception ModelStateException that gets thrown when validation fails on the server (model state reports validation errors when we use data annotations and use strong typed controller action parameters)
2. Custom controller action error filter HandleModelStateExceptionAttribute that catches custom exception and returns HTTP error status with model state error in the body

This provides the optimal infrastructure for jQuery Ajax calls to use their full potential with success and error handlers.

Client side code

$.ajax({
    type: "POST",
    url: "some/url",
    success: function(data, status, xhr) {
        // handle success
    },
    error: function(xhr, status, error) {
        // handle error
    }
});

Server side code

[HandleModelStateException]
public ActionResult Create(User user)
{
    if (!this.ModelState.IsValid)
    {
        throw new ModelStateException(this.ModelState);
    }

    // create new user because validation was successful
}

The whole problem is detailed in this blog post where you can find all the code to run this in your application.

The solution is actually described here: http://www.anujgakhar.com/2013/06/15/duplicates-in-a-repeater-are-not-allowed-in-angularjs/

AngularJS does not allow duplicates in a ng-repeat directive. This means if you are trying to do the following, you will get an error.

// This code throws the error "Duplicates in a repeater are not allowed.
// Repeater: row in [1,1,1] key: number:1"
<div ng-repeat="row in [1,1,1]">

However, changing the above code slightly to define an index to determine uniqueness as below will get it working again.

// This will work
<div ng-repeat="row in [1,1,1] track by $index">

Official docs are here: https://docs.angularjs.org/error/ngRepeat/dupes

You need to instruct the console to clear.

For serial terminals this was typically done through so called "escape sequences", where notably the vt100 set has become very commonly supported (and its close ANSI-cousin).

Windows has traditionally not supported such sequences "out-of-the-box" but relied on API-calls to do these things. For DOS-based versions of Windows, however, the ANSI.SYS driver could be installed to provide such support.

So if you are under Windows, you need to interact with the appropriate Windows API. I do not believe the standard Java runtime library contains code to do so.

From man curl:

-x, --proxy <[protocol://][user:password@]proxyhost[:port]>

     Use the specified HTTP proxy. 
     If the port number is not specified, it is assumed at port 1080.

General way:

export http_proxy=http://your.proxy.server:port/

Then you can connect through proxy from (many) application.

And, as per comment below, for https:

export https_proxy=https://your.proxy.server:port/

The canonical T-SQL (SqlServer) answer is to use a DELETE with JOIN as such

DELETE o
FROM Orders o
INNER JOIN Customers c
    ON o.CustomerId = c.CustomerId
WHERE c.FirstName = 'sklivvz'

This will delete all orders which have a customer with first name Sklivvz.

To resolve this error:

ORA-01653 unable to extend table by 1024 in tablespace your-tablespace-name

Just run this PL/SQL command for extended tablespace size automatically on-demand:

alter database datafile '<your-tablespace-name>.dbf' autoextend on maxsize unlimited;

I get this error in import big dump file, just run this command without stopping import routine or restarting the database.

Note: each data file has a limit of 32GB of size if you need more than 32GB you should add a new data file to your existing tablespace.

More info: alter_autoextend_on

This is easy to do, you can render the report as a PDF, and save the resulting byte array as a PDF file on disk. To do this in the background, that's more a question of how your app is written. You can just spin up a new thread, or use a BackgroundWorker (if this is a WinForms app), etc. There, of course, may be multithreading issues to be aware of.

Warning[] warnings;
string[] streamids;
string mimeType;
string encoding;
string filenameExtension;

byte[] bytes = reportViewer.LocalReport.Render(
    "PDF", null, out mimeType, out encoding, out filenameExtension,
    out streamids, out warnings);

using (FileStream fs = new FileStream("output.pdf", FileMode.Create))
{
    fs.Write(bytes, 0, bytes.Length);
}

It stands for Dimension, but is generally read as "Create Variable," or "Allocate Space for This."

You can use round function just to suppress scientific notation for specific dataframe:

df1.round(4)

or you can suppress is globally by:

pd.options.display.float_format = '{:.4f}'.format

As far as I can tell what you could do is "retire" your previous app and redirect all users to your new app. This procedure is not supported by Google (tsk... tsk...), but it could be implemented in four steps:

1. Change the current application to show a message to the users about the upgrade and redirect them to the new app listing. Probably a full screen message would do with some friendly text. This message could be triggered remotely ideally, but a cut-off date can be used too. (But then that will be a hard deadline for you, so be careful... ;))

2. Release the modified old app as an upgrade, maybe with some feature upgrades/bug fixes too, to "sweeten the deal" to the users. Still there is no guarantee that all users will upgrade, but probably the majority will do.

3. Prepare your new app with the updated package name and upload it to the store, then trigger the message in the old app (or just wait until it expires, if that was your choice).

4. Unpublish the old app in Play Store to avoid any new installs. Unpublishing an app doesn't mean the users who already installed it won't have access to it anymore, but at least the potential new users won't find it on the market.

Not ideal and can be annoying to the users, sometimes even impossible to implement due to the status/possibilities of the app. But since Google left us no choice this is the only way to migrate the users of the old apps to a "new" one (even if it is not really new). Not to mention that if you don't have access to the sources and code signing details for the old app then all you could do is hoping that he users will notice the new app...

If anybody figured out a better way by all means: please do tell.

Besides listing the files explicitly as shown by unwind and Wienczny, you can setup change lists and checkin these. These allow you to manage disjunct sets of changes to the same working copy.

You can read about them in the online version of the excellent SVN book.

Yes, you can do this.

1. Copy all of the cloned VM's files from its directory, and place it on its destination datastore.
2. In the VI client connected to the destination vCenter, go to the Inventory->Datastores view.
3. Open the datastore browser for the datastore where you placed the VM's files.
4. Find the .vmx file that you copied over and right-click it.
5. Choose 'Register Virtual Machine', and follow whatever prompts ensue. (Depending on your version of vCenter, this may be 'Add to Inventory' or some other variant)

The VM registration process should finish with the cloned VM usable in the new vCenter!

Good luck!

With MVC5 i have done it like this and it is 100% working code....

@Html.ActionLink(department.Name, "Index", "Employee", new { 
                            departmentId = department.DepartmentID }, null)

You guys can get an idea from this...

This is the simplest way to do it.

let total = parseInt(('100,000.00'.replace(',',''))) + parseInt(('500,000.00'.replace(',','')))

Consider the following query:

$iId = mysql_real_escape_string("1 OR 1=1");    
$sSql = "SELECT * FROM table WHERE id = $iId";

mysql_real_escape_string() will not protect you against this. The fact that you use single quotes (' ') around your variables inside your query is what protects you against this. The following is also an option:

$iId = (int)"1 OR 1=1";
$sSql = "SELECT * FROM table WHERE id = $iId";

This recursive function concatenates array of querysets into one queryset.

def merge_query(ar):
    if len(ar) ==0:
        return [ar]
    while len(ar)>1:
        tmp=ar[0] | ar[1]
        ar[0]=tmp
        ar.pop(1)
        return ar

If you're using ES2015 and you want to define your own object that iterates like a 2-D array, you can implement the iterator protocol by:

1. Defining an @@iterator function called Symbol.iterator which returns...
2. ...an object with a next() function that returns...
3. ...an object with one or two properties: an optional value with the next value (if there is one) and a boolean done which is true if we're done iterating.

A one-dimensional array iterator function would look like this:

// our custom Cubes object which implements the iterable protocol
function Cubes() {
    this.cubes = [1, 2, 3, 4];
    this.numVals = this.cubes.length;

    // assign a function to the property Symbol.iterator
    // which is a special property that the spread operator
    // and for..of construct both search for
    this[Symbol.iterator] = function () { // can't take args

        var index = -1; // keep an internal count of our index
        var self = this; // access vars/methods in object scope

        // the @@iterator method must return an object
        // with a "next()" property, which will be called
        // implicitly to get the next value
        return {
            // next() must return an object with a "done" 
            // (and optionally also a "value") property
            next: function() {
                index++;
                // if there's still some values, return next one
                if (index < self.numVals) {
                    return {
                        value: self.cubes[index],
                        done: false
                    };
                }
                // else there's no more values left, so we're done
                // IF YOU FORGET THIS YOU WILL LOOP FOREVER!
                return {done: true}
            }
        };
    };
}

Now, we can treat our Cubes object like an iterable:

var cube = new Cubes(); // construct our cube object

// both call Symbol.iterator function implicitly:
console.log([...cube]); // spread operator
for (var value of cube) { // for..of construct
    console.log(value);
}

To create our own 2-D iterable, instead of returning a value in our next() function, we can return another iterable:

function Cubes() {
    this.cubes = [
        [1, 2, 3, 4],
        [5, 6, 7, 8],
        [9, 10, 11, 12],
    ];
    this.numRows = this.cubes.length;
    this.numCols = this.cubes[0].length; // assumes all rows have same length

    this[Symbol.iterator] = function () {
        var row = -1;
        var self = this;

        // create a closure that returns an iterator
        // on the captured row index
        function createColIterator(currentRow) {
            var col = -1;
            var colIterator = {}
            // column iterator implements iterable protocol
            colIterator[Symbol.iterator] = function() {
                return {next: function() {
                    col++;
                    if (col < self.numCols) {
                        // return raw value
                        return {
                            value: self.cubes[currentRow][col],
                            done: false
                        };
                    }
                    return {done: true};
                }};
            }
            return colIterator;
        }

        return {next: function() {
            row++;
            if (row < self.numRows) {
                // instead of a value, return another iterator
                return {
                    value: createColIterator(row),
                    done: false
                };
            }
            return {done: true}
        }};
    };
}

Now, we can use nested iteration:

var cube = new Cubes();

// spread operator returns list of iterators, 
// each of which can be spread to get values
var rows = [...cube];
console.log([...rows[0]]);
console.log([...rows[1]]);
console.log([...rows[2]]);

// use map to apply spread operator to each iterable
console.log([...cube].map(function(iterator) { 
    return [...iterator];
}));

for (var row of cube) {
    for (var value of row) {
        console.log(value);
    }
}

Note that our custom iterable won't behave like a 2-D array in all cases; for example, we haven't implemented a map() function. This answer shows how you could implement a generator map function (see here for the difference between iterators and generators; also, generators are an ES2016 feature, not ES2015, so you'll need to change your babel presets if you're compiling with babel).

I lost somehow my temporary notepad++ files, they weren't showing in tabs. So I did some search in appdata folder, and I found all my temporary files there. It seems that they are stored there for a long time.

With current latest python 3.6.5

pip3 install PyQt5

works fine

std::map::find returns an iterator to the found element (or to the end() if the element was not found). So long as the map is not const, you can modify the element pointed to by the iterator:

std::map<char, int> m;
m.insert(std::make_pair('c', 0));  // c is for cookie

std::map<char, int>::iterator it = m.find('c'); 
if (it != m.end())
    it->second = 42;

I'm a beginner and wrote a script to ping multiple hosts.To ping multiple host you can use ipaddress module.

import ipaddress
from subprocess import Popen, PIPE

net4 = ipaddress.ip_network('192.168.2.0/24')
for x in net4.hosts():
    x = str(x)
    hostup = Popen(["ping", "-c1", x], stdout=PIPE)
    output = hostup.communicate()[0]
    val1 = hostup.returncode
 if val1 == 0:
    print(x, "is pinging")
 else:
    print(x, "is not responding")

You can animate it after the fadeIn completes using the callback as shown below:

$("#Friends").fadeIn('slow',function(){
  $(this).animate({'top': '-=30px'},'slow');
});

This doesn't directly answer the question but can be very useful, especially if you want something like all the numeric columns except for your id column and dependent variable.

numeric_cols <- sapply(dataframe, is.numeric) %>% which %>% 
                   names %>% setdiff(., c("id_variable", "dep_var"))

dataframe %<>% dplyr::mutate_at(numeric_cols, function(x) your_function(x))

To see the dynamic SQL generated, change to text mode (_shortcut: Ctrl-T), then use SELECT

PRINT LEN(@Query) -- Prints out 4273, which is correct as far as I can tell
--SET NOCOUNT ON
SELECT @Query

As for sp_executesql, try this (in text mode), it should show the three aaaaa...'s the middle one being the longest with 'SELECT ..' added. Watch the Ln... Col.. indicator in the status bar at bottom right showing 4510 at the end of the 2nd output.

declare @n nvarchar(max)
set @n = REPLICATE(convert(nvarchar(max), 'a'), 4500)
SET @N = 'SELECT ''' + @n + ''''
print @n   -- up to 4000
select @n  -- up to max
exec sp_Executesql @n

Try this

For red color,

<string name="hello_worldRed"><![CDATA[<b><font color=#FF0000>Hello world!</font></b>]]></string>

For blue,

<string name="hello_worldBlue"><![CDATA[<b><font color=#0000FF>Hello world!</font></b>]]></string>

In java code,

//red color text
TextView redColorTextView = (TextView)findViewById(R.id.redText);
String redString = getResources().getString(R.string.hello_worldRed)
redColorTextView.setText(Html.fromHtml(redString));

//Blue color text
TextView blueColorTextView = (TextView)findViewById(R.id.blueText);
String blueString = getResources().getString(R.string.hello_worldBlue)
blueColorTextView.setText(Html.fromHtml(blueString));

Use the following code:

if(processing == success) {
  header("Location:filename");
  exit();
}

And you are good to go.

Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.

I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.

If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.

I just ran into this problem. I was running my source from the command line and kept getting the same error. It turns out that I needed to remove the package name from my source code and then the command line compiler was happy.

The solutions above didn't work for me so maybe this will work for someone else with a similar problem.

Try this:

$(document).ready(function(){
    $("#showSimpleModal").click(function() {
        $("div#simpleModal").addClass("show");
        $("#videoContainer")[0].play();
        return false;   
    });

    $("#closeSimple").click(function() {
        $("div#simpleModal").removeClass("show");
        $("#videoContainer")[0].pause();
        return false;                   
    });
});

Regardless of the version, for your example, the <update> is:

{  $set: { lastLookedAt: Date.now() / 1000 }  }

However, depending on your version of MongoDB, the query will look different. Regardless of version, the key is that the empty condition {} will match any document. In the Mongo shell, or with any MongoDB client:

$version >= 3.2:

db.foo.updateMany( {}, <update> )

• {} is the condition (the empty condition matches any document)

3.2 > $version >= 2.2:

db.foo.update( {}, <update>, { multi: true } )

• {} is the condition (the empty condition matches any document)
• {multi: true} is the "update multiple documents" option

$version < 2.2:

db.foo.update( {}, <update>, false, true )

• {} is the condition (the empty condition matches any document)
• false is for the "upsert" parameter
• true is for the "multi" parameter (update multiple records)

The X-Frame-Options header is a security feature enforced at the browser level.

If you have control over your user base (IT dept for corp app), you could try something like a greasemonkey script (if you can a) deploy greasemonkey across everyone and b) deploy your script in a shared way)...

Alternatively, you can proxy their result. Create an endpoint on your server, and have that endpoint open a connection to the target endpoint, and simply funnel traffic backwards.

To do this for multiple dataframes, you can do a for loop over them:

fig = plt.figure(num=None, figsize=(10, 8))
ax = dict_of_dfs['FOO'].column.plot()
for BAR in dict_of_dfs.keys():
    if BAR == 'FOO':
        pass
    else:
        dict_of_dfs[BAR].column.plot(ax=ax)

Even though it has already been answered, I suggest a different approach that makes use of numpy.histogram. Such function given a sequence it returns the frequency of its elements grouped in bins.

Beware though: it works in this example because numbers are integers. If they where real numbers, then this solution would not apply as nicely.

>>> from numpy import histogram
>>> y = histogram (x, bins=x.max()-1)
>>> y
(array([5, 3, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
       1]),
 array([  1.,   2.,   3.,   4.,   5.,   6.,   7.,   8.,   9.,  10.,  11.,
        12.,  13.,  14.,  15.,  16.,  17.,  18.,  19.,  20.,  21.,  22.,
        23.,  24.,  25.]))

Just go to the project Properties->Project Facets

1. Uncheck the dynamic module, click apply.

2. Maven->update the project.

This can happen when you have used same session object for read & write. How? Say you have created one session. You read a record from employee table with primary key Emp_id=101 Now You have modified the record in Java. And you are going to save the Employee record in database. we have not closed session anywhere here. As the object that was read also persist in the session. It conflicts with the object that we wish to write. Hence this error comes.

If you have a branch different than master, one easy way is to check out that branch, then check out master. Voila, you are back at the tip of master. There's probably smarter ways...

If you are importing file1.py from file2.py and used this:

if __name__ == '__main__':
    # etc

Variables below that in file1.py cannot be imported to file2.py because __name__ does not equal __main__!

If you want to import something from file1.py to file2.py, you need to use this in file1.py:

if __name__ == 'file1':
    # etc

In case of doubt, make an assert statement to determine if __name__=='__main__'

You can do it by following way.

ALTER TABLE tableName drop column if exists columnName; 
ALTER TABLE tableName ADD COLUMN columnName character varying(8);

So it will drop the column if it is already exists. And then add the column to particular table.

For anyone who wants to loop through all query strings from a string

        foreach (var item in new Uri(urlString).Query.TrimStart('?').Split('&'))
        {
            var subStrings = item.Split('=');

            var key = subStrings[0];
            var value = subStrings[1];

            // do something with values
        }

int lastInt = integerList[integerList.Count-1];

While arguably being less clear this method is faster by roughly a factor of roughly 3.5 (At least on the box I used to test)

$foo = array(
    1 => "Value1",
    2 => "Value2",
    10 => "Value10"
);
while($bar = each($foo)){
    echo $bar[0] . " => " . $bar[1];
}

I would imagine that this is due to the fact the foreach copies the entire array before iterating over it.

The ONESHELL directive allows to write multiple line recipes to be executed in the same shell invocation.

all: foo

SOURCE_FILES = $(shell find . -name '*.c')

.ONESHELL:
foo: ${SOURCE_FILES}
    FILES=()
    for F in $^; do
        FILES+=($${F})
    done
    gcc "$${FILES[@]}" -o $@

There is a drawback though : special prefix characters (‘@’, ‘-’, and ‘+’) are interpreted differently.

I happened to be working in localhost , in windows 10, using WAMP, as it turns out, Wamp has a really accessible configuration interface to change the MySQL configuration. You just need to go to the Wamp panel, then to MySQL, then to settings and change the mode to sql-mode: none.(essentially disabling the strict mode) The following picture illustrates this.

The code block with the static modifier signifies a class initializer; without the static modifier the code block is an instance initializer.

Class initializers are executed in the order they are defined (top down, just like simple variable initializers) when the class is loaded (actually, when it's resolved, but that's a technicality).

Instance initializers are executed in the order defined when the class is instantiated, immediately before the constructor code is executed, immediately after the invocation of the super constructor.

If you remove static from int a, it becomes an instance variable, which you are not able to access from the static initializer block. This will fail to compile with the error "non-static variable a cannot be referenced from a static context".

If you also remove static from the initializer block, it then becomes an instance initializer and so int a is initialized at construction.

If you are using ubuntu you can take update

sudo apt-get update

And install extension in case of php 5.6

sudo apt-get install php5.6-intl

And in case of php 7.0

sudo apt-get install php7.0-intl

And restart your apache after

sudo service apache2 restart

If you are using xampp then remove semicolon ( ; ) in xampp/php/php.ini from below line

 ;extension=php_intl.dll

And then restart your xampp.

as aside tip make sure your button is not subclass of any custom class in story board , in such a case your code best place should be in custom class it self cause code works only out of the custom class if your button is subclass of the default UIButton class and outlet of it , hope this may help anyone wonders why corner radios doesn't apply on my button from code .

Based on the answers above I created this function that I have tested on IE 11, Chrome 36 and Firefox 29

function exportToCsv(filename, rows) {
    var processRow = function (row) {
        var finalVal = '';
        for (var j = 0; j < row.length; j++) {
            var innerValue = row[j] === null ? '' : row[j].toString();
            if (row[j] instanceof Date) {
                innerValue = row[j].toLocaleString();
            };
            var result = innerValue.replace(/"/g, '""');
            if (result.search(/("|,|\n)/g) >= 0)
                result = '"' + result + '"';
            if (j > 0)
                finalVal += ',';
            finalVal += result;
        }
        return finalVal + '\n';
    };

    var csvFile = '';
    for (var i = 0; i < rows.length; i++) {
        csvFile += processRow(rows[i]);
    }

    var blob = new Blob([csvFile], { type: 'text/csv;charset=utf-8;' });
    if (navigator.msSaveBlob) { // IE 10+
        navigator.msSaveBlob(blob, filename);
    } else {
        var link = document.createElement("a");
        if (link.download !== undefined) { // feature detection
            // Browsers that support HTML5 download attribute
            var url = URL.createObjectURL(blob);
            link.setAttribute("href", url);
            link.setAttribute("download", filename);
            link.style.visibility = 'hidden';
            document.body.appendChild(link);
            link.click();
            document.body.removeChild(link);
        }
    }
}

For example: https://jsfiddle.net/jossef/m3rrLzk0/

Always remember when we compare two strings. the comparison happens on chacracter basis. so '2' > '12' is true because the comparison will happen as '2' > '1' and in alphabetical way '2' is always greater than '1' as unicode. SO it will comeout true. I hope this helps.

Try this:

   var mydtn = DateTime.Today;
   var myDt = mydtn.Date;return myDt.ToString("d", CultureInfo.GetCultureInfo("en-US"));

@Jason is correct in a way but not entirely.

update

Update the registered submodules, i.e. clone missing submodules and checkout the commit specified in the index of the containing repository. This will make the submodules HEAD be detached unless --rebase or --merge is specified or the key submodule.$name.update is set to rebase or merge.

So, git submodule update does checkout, but it is to the commit in the index of the containing repository. It does not yet know of the new commit upstream at all. So go to your submodule, get the commit you want and commit the updated submodule state in the main repository and then do the git submodule update.

Given your specs, I'd use slice-assignment:

>>> L = ['title', 'email', 'password2', 'password1', 'first_name', 'last_name', 'next', 'newsletter']
>>> i = L.index('password2')
>>> L[i:i+2] = L[i+1:i-1:-1]
>>> L
['title', 'email', 'password1', 'password2', 'first_name', 'last_name', 'next', 'newsletter']

The right-hand side of the slice assignment is a "reversed slice" and could also be spelled:

L[i:i+2] = reversed(L[i:i+2])

if you find that more readable, as many would.

That's phpDoc syntax.

Create an empty folder and move the .mdb file to that folder. And try opening it from there. I tried it this way and it worked for me.

What the PHP Notice means and how to reproduce it:

If you send a PHP array into a function that expects a string like: echo or print, then the PHP interpreter will convert your array to the literal string Array, throw this Notice and keep going. For example:

php> print(array(1,2,3))

PHP Notice:  Array to string conversion in 
/usr/local/lib/python2.7/dist-packages/phpsh/phpsh.php(591) :
eval()'d code on line 1
Array

In this case, the function print dumps the literal string: Array to stdout and then logs the Notice to stderr and keeps going.

Another example in a PHP script:

<?php
    $stuff = array(1,2,3);
    print $stuff;  //PHP Notice:  Array to string conversion in yourfile on line 3
?>

Correction 1: use foreach loop to access array elements

http://php.net/foreach

$stuff = array(1,2,3);
foreach ($stuff as $value) {
    echo $value, "\n";
}

Prints:

1
2
3

Or along with array keys

$stuff = array('name' => 'Joe', 'email' => '[email protected]');
foreach ($stuff as $key => $value) {
    echo "$key: $value\n";
}

Prints:

name: Joe
email: [email protected]

Note that array elements could be arrays as well. In this case either use foreach again or access this inner array elements using array syntax, e.g. $row['name']

Correction 2: Joining all the cells in the array together:

In case it's just a plain 1-demensional array, you can simply join all the cells into a string using a delimiter:

<?php
    $stuff = array(1,2,3);
    print implode(", ", $stuff);    //prints 1, 2, 3
    print join(',', $stuff);        //prints 1,2,3

Correction 3: Stringify an array with complex structure:

In case your array has a complex structure but you need to convert it to a string anyway, then use http://php.net/json_encode

$stuff = array('name' => 'Joe', 'email' => '[email protected]');
print json_encode($stuff);

Prints

{"name":"Joe","email":"[email protected]"}

A quick peek into array structure: use the builtin php functions

If you want just to inspect the array contents for the debugging purpose, use one of the following functions. Keep in mind that var_dump is most informative of them and thus usually being preferred for the purpose

• http://php.net/print_r
• http://php.net/var_dump
• http://php.net/var_export

examples

$stuff = array(1,2,3);
print_r($stuff);
$stuff = array(3,4,5);
var_dump($stuff);

Prints:

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
)
array(3) {
  [0]=>
  int(3)
  [1]=>
  int(4)
  [2]=>
  int(5)
}

You can also get the tenant id, in fact all subscription details by logging into the url resources.azure.com

To anyone else who tried most of the solutions and still having problems.

My solution is different from the others, which is located at the bottom of this post, but before you try it make sure you have exhausted the following lists. To be sure, I have tried all of them but to no avail.

1. Recompile and redeploy from scratch, don't update the existing app. SO Answer

2. Grant IIS_IUSRS full access to the directory "C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files"

   Keep in mind the framework version you are using. If your app is using impersonation, use that identity instead of IIS_IUSRS

3. Delete all contents of the directory "C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files".

   Keep in mind the framework version you are using

4. Change the identity of the AppPool that your app is using, from ApplicatonPoolIdentity to NetworkService.

   IIS > Application Pools > Select current app pool > Advance Settings > Identity.

   SO Answer (please restore to default if it doesn't work)

5. Verify IIS Version and AppPool .NET version compatibility with your app. Highly applicable to first time deployments. SO Answer

6. Verify impersonation configuration if applicable. SO Answer

My Solution:

I found out that certain anti-virus softwares are actively blocking compilations of DLLs within the directory "Temporary ASP.NET Files", mine was McAfee, the IT people failed to notify me of the installation.

As per advice by both McAfee experts and Microsoft, you need to exclude the directory "Temporary ASP.NET Files" in the real time scanning.

Sources:

• McAfee Support Forum
• Microsoft Support
• Asp.Net Forum

Don't disable the Anti-Virus because it is only doing its job. Don't manually copy missing DLL files in the directory \Temporary ASP.NET Files{project name} because thats duct taping.

If someone used this:

val sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context)

PreferenceManager is now depricated, refactor to this:

val sharedPreferences = context.getSharedPreferences(context.packageName + "_preferences", Context.MODE_PRIVATE)

The first case is telling the web server that you are posting JSON data as in:

{ Name : 'John Smith', Age: 23}

The second option is telling the web server that you will be encoding the parameters in the URL as in:

Name=John+Smith&Age=23

You can create a new MongoDB ObjectId like this using mongoose:

var mongoose = require('mongoose');
var newId = new mongoose.mongo.ObjectId('56cb91bdc3464f14678934ca');
// or leave the id string blank to generate an id with a new hex identifier
var newId2 = new mongoose.mongo.ObjectId();

EDIT: Per @sshow's comment, if you're trying to run your node app on port 80, the below is not the best way to do it. Here's a better answer: How do I run Node.js on port 80?

Original Answer:

If you want to do this to run on port 80 (or want to set the env variable more permanently),

1. Open up your bash profile vim ~/.bash_profile
2. Add the environment variable to the file export PORT=80
3. Open up the sudoers config file sudo visudo
4. Add the following line to the file exactly as so Defaults env_keep +="PORT"

Now when you run sudo node app.js it should work as desired.

My contribution is aimed at those on a Mac, and it can be applied to not only those working on an iOS project (as implied by the question mentioning Xcode), but any type of project.

The easy way that I do it is to go into the terminal and run vim .gitignore and then add the files. Usually you can just copy what you need from one of the templates on GitHub at https://github.com/github/gitignore.

Step 1
While in your project, type the following command

vim .gitignore

Step 2
You now have your file open with Vim.

Press i to insert text. You will see that the file is ready when you see the --INSERT-- at the bottom.

Step 3 (option 1)
For Objective-C projects, you can copy from https://raw.githubusercontent.com/github/gitignore/master/Objective-C.gitignore and paste it into your .gitignore file:

Press Esc, type in :wq, and press Return. Which saves the file.

Step 3 (option 2)
Add whatever files apply to your project.

If you are not sure what to add, the best keywords to use in your search engine would be to include your project type and text editor. For example, if you use Sublime Text you would want to add

*.sublime-workspace

And if you are working with a Cordova project in Dreamweaver you would want to add

_notes
dwsync.xml

TRUNCATE is fast, DELETE is slow.

Although, TRUNCATE has no accountability.

console.log( Object.keys( {'a':1,'b':2} ) );

On the documentation:

http://docs.opencv.org/2.4/modules/core/doc/basic_structures.html#mat

It says:

(...) if you know the matrix element type, e.g. it is float, then you can use at<>() method

That is, you can use:

Mat M(100, 100, CV_64F);
cout << M.at<double>(0,0);

Maybe it is easier to use the Mat_ class. It is a template wrapper for Mat. Mat_ has the operator() overloaded in order to access the elements.

I think this may help:

Secondly, you need to be aware that the checked attribute RETURNS a string "true", "false"
Why is this important? Because you need to use the correct Type. A string, not a boolean. This also important when parsing your checkbox.
$('mycheckbox')[0].checked = "true"

if($('mycheckbox')[0].checked === "true"){ //do something }

You also need to realize that the "checked" ATTRIBUTE is for setting the value of the checkbox initially. This doesn't do much once the element is rendered to the DOM. Picture this working when the webpage loads and is initially parsed.
I'll go with IE's preference on this one: <input type="checkbox" checked="checked"/>

Lastly, the main aspect of confusion for a checkbox is that the checkbox UI element is not the same as the element's property value. They do not correlate directly. If you work in .net, you'll discover that the user "checking" a checkbox never reflects the actual bool value passed to the controller. To set the UI, I use both $('mycheckbox').val(true); and $('mycheckbox').attr('checked', 'checked');

Just to add to answers by Mr. Dimitrov and Jason, if you are using a specific profile and you have put your region setting there,then for all the requests you need to add

"--profile" option.

For example:

Lets say you have AWS Playground profile, and the ~/.aws/config has [profile playground] which further has something like,

[profile playground] region=us-east-1

then, use something like below

aws ecs list-container-instances --cluster default --profile playground

You could also consider:

RUN apt-get update && apt-get install -y iputils-ping

(as Contango comments: you must first run apt-get update, to avoid error with missing repository).

See "Replacing ifconfig with ip"

it is most often recommended to move forward with the command that has replaced ifconfig. That command is ip, and it does a great job of stepping in for the out-of-date ifconfig.

But as seen in "Getting a Docker container's IP address from the host", using docker inspect can be more useful depending on your use case.

For question 1 use os.getcwd() # get working dir and os.chdir(r'D:\Steam\steamapps\common') # set working dir

I recommend using sys.argv[0] for question 2 because sys.argv is immutable and therefore always returns the current file (module object path) and not affected by os.chdir(). Also you can do like this:

import os
this_py_file = os.path.realpath(__file__)

# vvv Below comes your code vvv #

but that snippet and sys.argv[0] will not work or will work wierd when compiled by PyInstaller because magic properties are not set in __main__ level and sys.argv[0] is the way your exe was called (means that it becomes affected by the working dir).

Let us say your table has following fields:

( pk_id int not null auto_increment primary key,
  col1 int,
  col2 varchar(10)
)

then, to copy values from one row to the other row with new key value, following query may help

insert into my_table( col1, col2 ) select col1, col2 from my_table where pk_id=?;

This will generate a new value for pk_id field and copy values from col1, and col2 of the selected row.

You can extend this sample to apply for more fields in the table.

UPDATE:
In due respect to the comments from JohnP and Martin -

We can use temporary table to buffer first from main table and use it to copy to main table again. Mere update of pk reference field in temp table will not help as it might already be present in the main table. Instead we can drop the pk field from the temp table and copy all other to the main table.

With reference to the answer by Tim Ruehsen in the referred posting:

CREATE TEMPORARY TABLE tmp SELECT * from my_table WHERE ...;
ALTER TABLE tmp drop pk_id; # drop autoincrement field
# UPDATE tmp SET ...; # just needed to change other unique keys
INSERT INTO my_table SELECT 0,tmp.* FROM tmp;
DROP TEMPORARY TABLE tmp;

Hope this helps.
