Programs & Examples On #Insertion sort

Selection Sort: As you start building the sorted sublist, the algorithm ensures that the sorted sublist is always completely sorted, not only in terms of it's own elements but also in terms of the complete array i.e. both sorted and unsorted sublist. Thus the new smallest element once found from the unsorted sublist would just be appended at the end of the sorted sublist.

Insertion Sort: The algorithm again divide the array into two part, but here the element is picked from second part and inserted at correct position to the first part. This never guarantees that the first part is sorted in terms of the complete array, though ofcourse in the final pass every element is at its correct sorted position.

On safari iPhone when battery is low and iPhone is on Low Power Mode it won`t autoplay, even if you have the following attributes: autoplay, loop, muted, playsinline set on your video html tag.

Walk around I found working is to have user gesture event to trigger video play:

document.body.addEventListener("touchstart", function () {
    var allVideos = document.querySelectorAll('video');
    for (var i = 0; i < allVideos.length; i++) {
        allVideos[i].play();
    }
},{ once: true });

Besides all of the other responses here, I really don't think that using backgroundColor in this way is the proper way to do things. Personally, I would create a UIImageView and insert it into your view hierarchy. You can either insert it into your top view and push it all the way to the back with sendSubviewToBack: or you can make the UIImageView the parent view.

I wouldn't worry about things like how efficient each implementation is at this point because unless you actually see an issue, it really doesn't matter. Your first priority for now should be writing code that you can understand and can easily be changed. Creating a UIColor to use as your background image isn't the clearest method of doing this.

To upload an image simple drag and drop from ur desktop or from anywhere n u can achieve this by copying the image and pasting it on the text area using ctrl+v

I think this working CodePen example that I created will show you exactly how to do what you want.

The template:

<section ng-app="app" ng-controller="MainCtrl">
  <span class="label">Ordered By: {{orderByField}}, Reverse Sort: {{reverseSort}}</span><br><br>
  <table class="table table-bordered">
    <thead>
      <tr>
        <th>
          <a href="#" ng-click="orderByField='firstName'; reverseSort = !reverseSort">
          First Name <span ng-show="orderByField == 'firstName'"><span ng-show="!reverseSort">^</span><span ng-show="reverseSort">v</span></span>
          </a>
        </th>
        <th>
          <a href="#" ng-click="orderByField='lastName'; reverseSort = !reverseSort">
            Last Name <span ng-show="orderByField == 'lastName'"><span ng-show="!reverseSort">^</span><span ng-show="reverseSort">v</span></span>
          </a>
        </th>
        <th>
          <a href="#" ng-click="orderByField='age'; reverseSort = !reverseSort">
          Age <span ng-show="orderByField == 'age'"><span ng-show="!reverseSort">^</span><span ng-show="reverseSort">v</span></span>
          </a>
        </th>
      </tr>
    </thead>
    <tbody>
      <tr ng-repeat="emp in data.employees|orderBy:orderByField:reverseSort">
        <td>{{emp.firstName}}</td>
        <td>{{emp.lastName}}</td>
        <td>{{emp.age}}</td>
      </tr>
    </tbody>
  </table>
</section>

The JavaScript code:

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

app.controller('MainCtrl', function($scope) {
  $scope.orderByField = 'firstName';
  $scope.reverseSort = false;

  $scope.data = {
    employees: [{
      firstName: 'John',
      lastName: 'Doe',
      age: 30
    },{
      firstName: 'Frank',
      lastName: 'Burns',
      age: 54
    },{
      firstName: 'Sue',
      lastName: 'Banter',
      age: 21
    }]
  };
});

I know you said you want to understand group by if you have data like this:

COL-A  COL-B  COL-C  COL-D
  1      Ac      C1     D1
  2      Bd      C2     D2
  3      Ba      C1     D3
  4      Ab      C1     D4
  5      C       C2     D5

And you want to make the data appear like:

COL-A  COL-B  COL-C  COL-D
  4      Ab      C1     D4
  1      Ac      C1     D1
  3      Ba      C1     D3
  2      Bd      C2     D2
  5      C       C2     D5

You use:

select * from table_name
order by col-c,colb

Because I think this is what you intend to do.

Here's another way that might be faster, in terms of compute time, than iterating. Not sure. The idea is to convert the array to a string, truncate it, and get the size of the new array.

For example, to find the index of 'd':

arr=(a b c d)    
temp=`echo ${arr[@]}`
temp=( ${temp%%d*} )
index=${#temp[@]}

You could turn this into a function like:

get-index() {

    Item=$1
    Array="$2[@]"

    ArgArray=( ${!Array} )
    NewArray=( ${!Array%%${Item}*} )

    Index=${#NewArray[@]}

    [[ ${#ArgArray[@]} == ${#NewArray[@]} ]] && echo -1 || echo $Index

}

You could then call:

get-index d arr

and it would echo back 3, which would be assignable with:

index=`get-index d arr`

IEnumerable describes behavior, while List is an implementation of that behavior. When you use IEnumerable, you give the compiler a chance to defer work until later, possibly optimizing along the way. If you use ToList() you force the compiler to reify the results right away.

Whenever I'm "stacking" LINQ expressions, I use IEnumerable, because by only specifying the behavior I give LINQ a chance to defer evaluation and possibly optimize the program. Remember how LINQ doesn't generate the SQL to query the database until you enumerate it? Consider this:

public IEnumerable<Animals> AllSpotted()
{
    return from a in Zoo.Animals
           where a.coat.HasSpots == true
           select a;
}

public IEnumerable<Animals> Feline(IEnumerable<Animals> sample)
{
    return from a in sample
           where a.race.Family == "Felidae"
           select a;
}

public IEnumerable<Animals> Canine(IEnumerable<Animals> sample)
{
    return from a in sample
           where a.race.Family == "Canidae"
           select a;
}

Now you have a method that selects an initial sample ("AllSpotted"), plus some filters. So now you can do this:

var Leopards = Feline(AllSpotted());
var Hyenas = Canine(AllSpotted());

So is it faster to use List over IEnumerable? Only if you want to prevent a query from being executed more than once. But is it better overall? Well in the above, Leopards and Hyenas get converted into single SQL queries each, and the database only returns the rows that are relevant. But if we had returned a List from AllSpotted(), then it may run slower because the database could return far more data than is actually needed, and we waste cycles doing the filtering in the client.

In a program, it may be better to defer converting your query to a list until the very end, so if I'm going to enumerate through Leopards and Hyenas more than once, I'd do this:

List<Animals> Leopards = Feline(AllSpotted()).ToList();
List<Animals> Hyenas = Canine(AllSpotted()).ToList();

I think you conclusions are correct but not accurate.

As the docs indicates, socket.recv is majorly focused on the network buffers.

When socket is blocking, socket.recv will return as long as the network buffers have bytes. If bytes in the network buffers are more than socket.recv can handle, it will return the maximum number of bytes it can handle. If bytes in the network buffers are less than socket.recv can handle, it will return all the bytes in the network buffers.

[+]is simpler

    String s = "ddjdjdj+kfkfkf";

    if(s.contains ("+"))
    {
        String parts[] = s.split("[+]");
        s =  parts[0]; // i want to strip part after  +
    }
    System.out.println(s);

The following code send and recieve the current date and time from and to the server

//The following code is for the server application:

namespace Server
{
    class Program
    {
        const int PORT_NO = 5000;
        const string SERVER_IP = "127.0.0.1";

The Servlet 3.0 spec doesn't seem to provide a hint on how a container should order filters that have been declared via annotations. It is clear how about how to order filters via their declaration in the web.xml file, though.

Be safe. Use the web.xml file order filters that have interdependencies. Try to make your filters all order independent to minimize the need to use a web.xml file.

Python 3:

user225312's answer is correct:

A. To count number of characters in str object, you can use len() function:

>>> print(len('please anwser my question'))
25

B. To get memory size in bytes allocated to store str object, you can use sys.getsizeof() function

>>> from sys import getsizeof
>>> print(getsizeof('please anwser my question'))
50

Python 2:

It gets complicated for Python 2.

A. The len() function in Python 2 returns count of bytes allocated to store encoded characters in a str object.

Sometimes it will be equal to character count:

>>> print(len('abc'))
3

But sometimes, it won't:

>>> print(len('???'))  # String contains Cyrillic symbols
6

That's because str can use variable-length encoding internally. So, to count characters in str you should know which encoding your str object is using. Then you can convert it to unicode object and get character count:

>>> print(len('???'.decode('utf8'))) #String contains Cyrillic symbols 
3

B. The sys.getsizeof() function does the same thing as in Python 3 - it returns count of bytes allocated to store the whole string object

>>> print(getsizeof('???'))
27
>>> print(getsizeof('???'.decode('utf8')))
32

I had this error in a more spooky way: The network tab and the chrome://net-internals/#events did not show the request after the js was completed. When pausing the js in the error callcack the network tab did show the request as (cancelled). The was consistently called for exactly one (always the same) of several similar requests in a webpage. After restarting Chrome the error did not rise again!

To view Theme files for ST3, install PackageResourceViewer via PackageControl.

Then, you can use the Ctrl + Shift + P >> PackageResourceViewer: Open Resource to view theme files.

To edit a specific background color, you need to create a new file in your user packages folder Packages/User/SublimeLinter with the same name as the theme currently applied to your sublime text file.

However, if your theme is a 3rd party theme package installed via package control, you can edit the hex value in that file directly, under background. For example:

<dict>
  <dict>
    <key>background</key>
    <string>#073642</string>
  </dict>
</dict>

Otherwise, if you are trying to modify a native sublime theme, add the following to the new file you create (named the same as the native theme, such as Monokai.sublime-color-scheme) with your color choice

{
  "globals":
  {
      "background": "rgb(5,5,5)"
  }
}

Then, you can open the file you wish the syntax / color to be applied to and then go to Syntax-Specific settings (under Preferences) and add the path of the file to the syntax specific settings file like so:

{
    "color_scheme": "Packages/User/SublimeLinter/Monokai.sublime-color-scheme"
}

Note that if you have installed a theme via package control, it probably has the .tmTheme file extension.

If you are wanting to edit the background color of the sidebar to be darker, go to Preferences > Theme > Adaptive.sublime-theme

This my answer based on my personal experience and info gleaned from the accepted answer on this page, if you'd like more information.

If you are using Kotlin for Android development then you can add TextChangedListener() using this code:

myTextField.addTextChangedListener(object : TextWatcher{
        override fun afterTextChanged(s: Editable?) {}

        override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {}

        override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {}
    })

Wrap all the children inside of another LinearLayout with wrap_content for both the width and the height as well as the vertical orientation.

Not sure if there was file corruption or what, but after confirming proper pom configuration I was able to resolve this issue by deleting the jar from my local m2 repository, forcing Maven to download it again when I ran the tests.

I have read the other answers and found it important to note a few other things:

1.) For Mac users: When you click "Load unpacked extension...", the Library folder is by default hidden and (even if the Show Hidden files option is toggled on your Mac) it might not show up in Chrome's finder window.

2.) The sub folder containing the extension is a random alpha-numeric string named after the extension's ID, which can be found on Chrome's extension page if Developer flag is set to true. (Upper right hand checkbox on the extensions page)

awk -F " " '($1=="A1") {print $NF}' FILE | tail -n 1

Use awk with field separator -F set to a space " ".

Use the pattern $1=="A1" and action {print $NF}, this will print the last field in every record where the first field is "A1". Pipe the result into tail and use the -n 1 option to only show the last line.

If you are using kotlin,consider these library. It's build for kotlin language.

AndroidHttpServer is a simple demo using ServerSocket to handle http request

AndroidHttpServer is very small , but the feature is less as well.

Ktor is a very nice library,and the usage is simple too

Thanks for the info, think I see the problem. This is a bug in hive-go that only shows up when you add a host. The last lines of it are:

app.listen(3001);
console.log("... port %d in %s mode", app.address().port, app.settings.env);

When you add the host on the first line, it is crashing when it calls app.address().port.

The problem is the potentially asynchronous nature of .listen(). Really it should be doing that console.log call inside a callback passed to listen. When you add the host, it tries to do a DNS lookup, which is async. So when that line tries to fetch the address, there isn't one yet because the DNS request is running, so it crashes.

Try this:

app.listen(3001, 'localhost', function() {
  console.log("... port %d in %s mode", app.address().port, app.settings.env);
});

I think actually nvarchar(MAX) can store approximately 1070000000 chars.

Yes. You can use java.util.formatter. You can use a formatting string like "%10.2f"

<FORM NAME=frm1 ...>
Name: <input type=textbox name=txtName id=txtName>
<BR>
<input type=button value="Submit" onclick=Validate()>



<Script>
    function Validate() { 
        Msg = ""

// Check fields
        if(frm1.txtName.value fails this) {
            Msg += "\n    The Name Field is improper"
        }
// Do the same for the rest of the form

        if(Msg == "") {
            frm1.submit()
        } else {
            alert("Your form has errors\n" + Msg)
        }
    }
</SCRIPT>

In MySQL itself, you can specify CSV output like:

SELECT order_id,product_name,qty
FROM orders
INTO OUTFILE '/tmp/orders.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'

From http://www.tech-recipes.com/rx/1475/save-mysql-query-results-into-a-text-or-csv-file/

Your problem is that you have to change:

printf("%"); 

to

printf("%%");

Or you could use ASCII code and write:

printf("%c", 37);

:)

As an extension to @JBNizet's answer for more technical users here's what implementation of org.w3c.dom.Node interface in com.sun.org.apache.xerces.internal.dom.ParentNode looks like, gives you the idea how it actually works.

public void normalize() {
    // No need to normalize if already normalized.
    if (isNormalized()) {
        return;
    }
    if (needsSyncChildren()) {
        synchronizeChildren();
    }
    ChildNode kid;
    for (kid = firstChild; kid != null; kid = kid.nextSibling) {
         kid.normalize();
    }
    isNormalized(true);
}

It traverses all the nodes recursively and calls kid.normalize()
This mechanism is overridden in org.apache.xerces.dom.ElementImpl

public void normalize() {
     // No need to normalize if already normalized.
     if (isNormalized()) {
         return;
     }
     if (needsSyncChildren()) {
         synchronizeChildren();
     }
     ChildNode kid, next;
     for (kid = firstChild; kid != null; kid = next) {
         next = kid.nextSibling;

         // If kid is a text node, we need to check for one of two
         // conditions:
         //   1) There is an adjacent text node
         //   2) There is no adjacent text node, but kid is
         //      an empty text node.
         if ( kid.getNodeType() == Node.TEXT_NODE )
         {
             // If an adjacent text node, merge it with kid
             if ( next!=null && next.getNodeType() == Node.TEXT_NODE )
             {
                 ((Text)kid).appendData(next.getNodeValue());
                 removeChild( next );
                 next = kid; // Don't advance; there might be another.
             }
             else
             {
                 // If kid is empty, remove it
                 if ( kid.getNodeValue() == null || kid.getNodeValue().length() == 0 ) {
                     removeChild( kid );
                 }
             }
         }

         // Otherwise it might be an Element, which is handled recursively
         else if (kid.getNodeType() == Node.ELEMENT_NODE) {
             kid.normalize();
         }
     }

     // We must also normalize all of the attributes
     if ( attributes!=null )
     {
         for( int i=0; i<attributes.getLength(); ++i )
         {
             Node attr = attributes.item(i);
             attr.normalize();
         }
     }

    // changed() will have occurred when the removeChild() was done,
    // so does not have to be reissued.

     isNormalized(true);
 } 

Hope this saves you some time.

You can have a look at the EL (expression language) description here.

Both your code are correct, but I prefer the second one, as comparing a boolean to true or false is redundant.

For better readibility, you can also use the not operator:

<c:if test="${not theBooleanVariable}">It's false!</c:if>

I would use the SplFileObject class...

$file = new SplFileObject("filename");
if (!$file->eof()) {
     $file->seek($lineNumber);
     $contents = $file->current(); // $contents would hold the data from line x
}

Just add \ at the end of line. For example

one\
two

Will become

one
two

It's also better than two spaces because it's visible.

On ARM, there is no branch needed, because every instruction has a 4-bit condition field, which tests (at zero cost) any of 16 different different conditions that may arise in the Processor Status Register, and if the condition on an instruction is false, the instruction is skipped. This eliminates the need for short branches, and there would be no branch prediction hit for this algorithm. Therefore, the sorted version of this algorithm would run slower than the unsorted version on ARM, because of the extra overhead of sorting.

The inner loop for this algorithm would look something like the following in ARM assembly language:

MOV R0, #0   // R0 = sum = 0
MOV R1, #0   // R1 = c = 0
ADR R2, data // R2 = addr of data array (put this instruction outside outer loop)
.inner_loop  // Inner loop branch label
    LDRB R3, [R2, R1]   // R3 = data[c]
    CMP R3, #128        // compare R3 to 128
    ADDGE R0, R0, R3    // if R3 >= 128, then sum += data[c] -- no branch needed!
    ADD R1, R1, #1      // c++
    CMP R1, #arraySize  // compare c to arraySize
    BLT inner_loop      // Branch to inner_loop if c < arraySize

But this is actually part of a bigger picture:

CMP opcodes always update the status bits in the Processor Status Register (PSR), because that is their purpose, but most other instructions do not touch the PSR unless you add an optional S suffix to the instruction, specifying that the PSR should be updated based on the result of the instruction. Just like the 4-bit condition suffix, being able to execute instructions without affecting the PSR is a mechanism that reduces the need for branches on ARM, and also facilitates out of order dispatch at the hardware level, because after performing some operation X that updates the status bits, subsequently (or in parallel) you can do a bunch of other work that explicitly should not affect (or be affected by) the status bits, then you can test the state of the status bits set earlier by X.

The condition testing field and the optional "set status bit" field can be combined, for example:

• ADD R1, R2, R3 performs R1 = R2 + R3 without updating any status bits.
• ADDGE R1, R2, R3 performs the same operation only if a previous instruction that affected the status bits resulted in a Greater than or Equal condition.
• ADDS R1, R2, R3 performs the addition and then updates the N, Z, C and V flags in the Processor Status Register based on whether the result was Negative, Zero, Carried (for unsigned addition), or oVerflowed (for signed addition).
• ADDSGE R1, R2, R3 performs the addition only if the GE test is true, and then subsequently updates the status bits based on the result of the addition.

Most processor architectures do not have this ability to specify whether or not the status bits should be updated for a given operation, which can necessitate writing additional code to save and later restore status bits, or may require additional branches, or may limit the processor's out of order execution efficiency: one of the side effects of most CPU instruction set architectures forcibly updating status bits after most instructions is that it is much harder to tease apart which instructions can be run in parallel without interfering with each other. Updating status bits has side effects, therefore has a linearizing effect on code. ARM's ability to mix and match branch-free condition testing on any instruction with the option to either update or not update the status bits after any instruction is extremely powerful, for both assembly language programmers and compilers, and produces very efficient code.

When you don't have to branch, you can avoid the time cost of flushing the pipeline for what would otherwise be short branches, and you can avoid the design complexity of many forms of speculative evalution. The performance impact of the initial naive imlementations of the mitigations for many recently discovered processor vulnerabilities (Spectre etc.) shows you just how much the performance of modern processors depends upon complex speculative evaluation logic. With a short pipeline and the dramatically reduced need for branching, ARM just doesn't need to rely on speculative evaluation as much as CISC processors. (Of course high-end ARM implementations do include speculative evaluation, but it's a smaller part of the performance story.)

If you have ever wondered why ARM has been so phenomenally successful, the brilliant effectiveness and interplay of these two mechanisms (combined with another mechanism that lets you "barrel shift" left or right one of the two arguments of any arithmetic operator or offset memory access operator at zero additional cost) are a big part of the story, because they are some of the greatest sources of the ARM architecture's efficiency. The brilliance of the original designers of the ARM ISA back in 1983, Steve Furber and Roger (now Sophie) Wilson, cannot be overstated.

Right, but as long as you use ASCII characters even a multibyte character set would still give a limitation of exactly 30 characters... so unless you want to put hearts and smiling cats in you're DB names your fine...

Below code will remove all punctuation marks as well as non alphabetic characters. Copied from their book.

import nltk

s = "I can't do this now, because I'm so tired.  Please give me some time. @ sd  4 232"

words = nltk.word_tokenize(s)

words=[word.lower() for word in words if word.isalpha()]

print(words)

output

['i', 'ca', 'do', 'this', 'now', 'because', 'i', 'so', 'tired', 'please', 'give', 'me', 'some', 'time', 'sd']

You can do this:

gdb --args path/to/executable -every -arg you can=think < of

The magic bit being --args.

Just type run in the gdb command console to start debugging.

A string is just a sequence of bytes, hence it's actually binary data in PHP. What exactly are you trying to do?

EDIT

If you want to store binary data in your database, the problem most often is the column definition in your database. PHP does not differentiate between binary data and strings, but databases do. In MySQL for example you should store binary data in BINARY, VARBINARY or BLOB columns.

Another option would be to base64_encode your PHP string and store it in some VARCHAR or TEXT column in the database. But be aware that the string's length will increase when base64_encode is used.

On 5.1 I could only get this to work.

<a href="{{ URL::previous() }}" class="btn btn-default">Back</a>

just click file in your android studio then click Sync Project with Gradle Files..

if it won't work, click Build click Clean Project.

it always work for me

You can cast datetime to time

select CAST(GETDATE() as time)

If you want a hh:mm format

select cast(CAST(GETDATE() as time) as varchar(5))

A better regex to use to check if a string is HTML is:

/^/

For example:

/^/.test('') // true
/^/.test('foo bar baz') //true
/^/.test('<p>fizz buzz</p>') //true

In fact, it's so good, that it'll return true for every string passed to it, which is because every string is HTML. Seriously, even if it's poorly formatted or invalid, it's still HTML.

If what you're looking for is the presence of HTML elements, rather than simply any text content, you could use something along the lines of:

/<\/?[a-z][\s\S]*>/i.test()

It won't help you parse the HTML in any way, but it will certainly flag the string as containing HTML elements.

For the ones that using Xamarin.IOS you can do like this:

new UIAlertView(null, message, null, "OK", null).Show();

using UIKit; is required.

var fileName = "something.extension";
fileName.slice(0, -path.extname(fileName).length) // === "something"

From my point of view static variable should be only read only data or variables created by convention.

For example we have a ui of some project, and we have a list of countries, languages, user roles, etc. And we have class to organize this data. we absolutely sure that app will not work without this lists. so the first that we do on app init is checking this list for updates and getting this list from api (if needed). So we agree that this data is "always" present in app. It is practically read only data so we don't need to take care of it's state - thinking about this case we really don't want to have a lot of instances of those data - this case looks a perfect candidate to be static.

Assuming that you mean "When using ajax" and "An HTTP Request header", then use the headers property in the object you pass to ajax()

headers(added 1.5)

Default: {}

A map of additional header key/value pairs to send along with the request. This setting is set before the beforeSend function is called; therefore, any values in the headers setting can be overwritten from within the beforeSend function.

You can use T-SQL:

use master
GO
CREATE LOGIN [NT AUTHORITY\LOCALSERVICE] FROM WINDOWS WITH
DEFAULT_DATABASE=yourDbName
GO
CREATE LOGIN [NT AUTHORITY\NETWORKSERVICE] FROM WINDOWS WITH
DEFAULT_DATABASE=yourDbName

I use this as a part of restore from production server to testing machine:

USE master
GO
ALTER DATABASE yourDbName SET OFFLINE WITH ROLLBACK IMMEDIATE
RESTORE DATABASE yourDbName FROM DISK = 'd:\DropBox\backup\myDB.bak'
ALTER DATABASE yourDbName SET ONLINE
GO
CREATE LOGIN [NT AUTHORITY\LOCALSERVICE] FROM WINDOWS WITH
DEFAULT_DATABASE=yourDbName
GO
CREATE LOGIN [NT AUTHORITY\NETWORKSERVICE] FROM WINDOWS WITH
DEFAULT_DATABASE=yourDbName
GO

You will need to use localized name of services in case of German or French Windows, see How to create a SQL Server login for a service account on a non-English Windows?

JSON can be written into local storage using the JSON.stringify to serialize a JS object. You cannot write to a JSON file using only JS. Only cookies or local storage

    var obj = {"nissan": "sentra", "color": "green"};

localStorage.setItem('myStorage', JSON.stringify(obj));

And to retrieve the object later

var obj = JSON.parse(localStorage.getItem('myStorage'));

You don't need to specify the module path per se. CMake ships with its own set of built-in find_package scripts, and their location is in the default CMAKE_MODULE_PATH.

The more normal use case for dependent projects that have been CMakeified would be to use CMake's external_project command and then include the Use[Project].cmake file from the subproject. If you just need the Find[Project].cmake script, copy it out of the subproject and into your own project's source code, and then you won't need to augment the CMAKE_MODULE_PATH in order to find the subproject at the system level.

use dnsmasq

pretending you're using a debian-based dist(ubuntu,mint..), check if it's installed with

(sudo) systemctl status dnsmasq

If it is just disabled start it with

(sudo) systemctl start dnsmasq

If you have to install it, write

(sudo) apt-get install dnsmasq

To define domains to resolve edit /etc/dnsmasq.conf like this

address=/example.com/127.0.0.1

to resolve *.example.com

! You need to reload dnsmasq to take effect for the changes !

systemctl reload dnsmasq

Just add

.flex-control-thumbs li {
width: auto; 
}

What you are doing right now is you are adding . on the string and not concatenating. It should be,

$result = mysqli_query($con,"SELECT `note` FROM `glogin_users` WHERE email = '".$email."'");

or simply

$result = mysqli_query($con,"SELECT `note` FROM `glogin_users` WHERE email = '$email'");

You should first take a look at this. This explains what happens when you import a package. For convenience:

The import statement uses the following convention: if a package’s __init__.py code defines a list named __all__, it is taken to be the list of module names that should be imported when from package import * is encountered. It is up to the package author to keep this list up-to-date when a new version of the package is released. Package authors may also decide not to support it, if they don’t see a use for importing * from their package.

So PyCharm respects this by showing a warning message, so that the author can decide which of the modules get imported when * from the package is imported. Thus this seems to be useful feature of PyCharm (and in no way can it be called a bug, I presume). You can easily remove this warning by adding the names of the modules to be imported when your package is imported in the __all__ variable which is list, like this

__init__.py

from . import MyModule1, MyModule2, MyModule3
__all__ = [MyModule1, MyModule2, MyModule3]

After you add this, you can ctrl+click on these module names used in any other part of your project to directly jump to the declaration, which I often find very useful.

I did the following to get my Mac to see the devices again:

• Run android update adb
• Run adb kill-server
• Run adb start-server

At this point, calling adb devices started returning devices again. Now run or debug your project to test it on your device.

Hope below Oracle query can help:

WITH Temp_table AS
(
    Select id, name, othercolumns, ROW_NUMBER() over (PARTITION BY name ORDER BY ID 
    desc)as rank from messages
)
Select id, name,othercolumns from Temp_table where rank=1

The installation process adds the phpMyAdmin Apache configuration file into the /etc/apache2/conf-enabled/ directory, where it is read automatically. The only thing you need to do is explicitly enable the mbstring PHP extension, Because sometimes you forgot to enable the mbstring mode so simply type the below command to enabled the mbstring mode...

   sudo phpenmod mbstring

Afterward, restart Apache for your changes to be recognized:

sudo systemctl restart apache2

I like to use the wrapper (adapter pattern) when I am wrapping the object itself. I'm not sure I'd use that for wrapping an extension method, which is not part of the object.

I use an internal Lazy Injectable Property of either type Action, Func, Predicate, or delegate and allow for injecting (swapping out) the method during a unit test.

    internal Func<IMyObject, string, object> DoWorkMethod
    {
        [ExcludeFromCodeCoverage]
        get { return _DoWorkMethod ?? (_DoWorkMethod = (obj, val) => { return obj.DoWork(val); }); }
        set { _DoWorkMethod = value; }
    } private Func<IMyObject, string, object> _DoWorkMethod;

Then you call the Func instead of the actual method.

    public object SomeFunction()
    {
        var val = "doesn't matter for this example";
        return DoWorkMethod.Invoke(MyObjectProperty, val);
    }

For a more complete example, check out http://www.rhyous.com/2016/08/11/unit-testing-calls-to-complex-extension-methods/

The legacy solution, before 1.6, was to use .attr and handle the returned value as a bool. The main problem is that the returned type of .attr has changed to string, and therefore the comparison with == true is broken (see http://jsfiddle.net/2vene/1/ (and switch the jquery-version)).

With 1.6 .prop was introduced, which returns a bool.

Nevertheless, I suggest to use .is(), as the returned type is intrinsically bool, like:

$('#dropUnit').is(':disabled');
$('#dropUnit').is(':enabled');

Furthermore .is() is much more natural (in terms of "natural language") and adds more conditions than a simple attribute-comparison (eg: .is(':last'), .is(':visible'), ... please see documentation on selectors).

You should use data.response in your JS instead of json.response.

  [HttpPost]
    public async Task<ActionResult> Capture(string imageData)
    {                      
        if (imageData.Length > 0)
        {
            var imageBytes = Convert.FromBase64String(imageData);
            using (var stream = new MemoryStream(imageBytes))
            {
                var result = (JsonResult)await IdentifyFace(stream);
                var serializer = new JavaScriptSerializer();
                var faceRecon = serializer.Deserialize<FaceIdentity>(serializer.Serialize(result.Data));

                if (faceRecon.Success) return RedirectToAction("Index", "Auth", new { param = serializer.Serialize(result.Data) });

            }
        }

        return Json(new { success = false, responseText = "Der opstod en fejl - Intet billede, manglede data." }, JsonRequestBehavior.AllowGet);

    }


// GET: Auth
    [HttpGet]
    public ActionResult Index(string param)
    {
        var serializer = new JavaScriptSerializer();
        var faceRecon = serializer.Deserialize<FaceIdentity>(param);


        return View(faceRecon);
    }

There are many LINQ equivalents for Java, see here for a comparison.

For a typesafe Quaere/LINQ style framework, consider using Querydsl. Querydsl supports JPA/Hibernate, JDO, SQL and Java Collections.

I am the maintainer of Querydsl, so this answer is biased.

Everything that is business logic belongs in a model, whether it is a database query, calculations, a REST call, etc.

You can have the data access in the model itself, the MVC pattern doesn't restrict you from doing that. You can sugar coat it with services, mappers and what not, but the actual definition of a model is a layer that handles business logic, nothing more, nothing less. It can be a class, a function, or a complete module with a gazillion objects if that's what you want.

It's always easier to have a separate object that actually executes the database queries instead of having them being executed in the model directly: this will especially come in handy when unit testing (because of the easiness of injecting a mock database dependency in your model):

class Database {
   protected $_conn;

   public function __construct($connection) {
       $this->_conn = $connection;
   }

   public function ExecuteObject($sql, $data) {
       // stuff
   }
}

abstract class Model {
   protected $_db;

   public function __construct(Database $db) {
       $this->_db = $db;
   }
}

class User extends Model {
   public function CheckUsername($username) {
       // ...
       $sql = "SELECT Username FROM" . $this->usersTableName . " WHERE ...";
       return $this->_db->ExecuteObject($sql, $data);
   }
}

$db = new Database($conn);
$model = new User($db);
$model->CheckUsername('foo');

Also, in PHP, you rarely need to catch/rethrow exceptions because the backtrace is preserved, especially in a case like your example. Just let the exception be thrown and catch it in the controller instead.

Keyguard basically refers to the code that handles the unlocking of the phone. it's like the keypad lock on your nokia phone a few years back just with the utility on a touchscreen.

Create a separate ul.nav for just that list item and float that ul right.

If App Pool has trouble restarting or simply doesn't want to restart, verify if windows made recent update on ASP.NET v4.0 or other App Pool. That is what happend in my case. I simply restarted my computer, then restarted ASP.NET v4.0 App Pool and everything was working again!

Add new column to your table and perfrom the query:

UPDATE tbl SET combined = CONCAT(zipcode, ' - ', city, ', ', state)

You can use in-place operator new. This would be a bit horrible, and I'd recommend keeping in a factory.

Car* createCars(unsigned number)
{
    if (number == 0 )
        return 0;
    Car* cars = reinterpret_cast<Car*>(new char[sizeof(Car)* number]);
    for(unsigned carId = 0;
        carId != number;
        ++carId)
    {
        new(cars+carId) Car(carId);
    }
    return cars;
}

And define a corresponding destroy so as to match the new used in this.

See os.path module for some useful functions on pathnames. To check if an existing file is executable, use os.access(path, mode), with the os.X_OK mode.

os.X_OK

Value to include in the mode parameter of access() to determine if path can be executed.

EDIT: The suggested which() implementations are missing one clue - using os.path.join() to build full file names.

If order is preserved between files you might also prefer difflib. Although Rob?'s result is the bona-fide standard for intersections you might actually be looking for a rough diff-like:

from difflib import Differ

with open('cfg1.txt') as f1, open('cfg2.txt') as f2:
    differ = Differ()

    for line in differ.compare(f1.readlines(), f2.readlines()):
        if line.startswith(" "):
            print(line[2:], end="")

That said, this has a different behaviour to what you asked for (order is important) even though in this instance the same output is produced.

I think you want to take a look at jQuery since that Javascript library provides a lot of functionality you might want to use in this kind of cases. In your case you could write (or find one on the internet) a hasAttribute method, like so (not tested):

$.fn.hasAttribute = function(tagName, attrName){
  var result = [];
  $.each($(tagName), function(index, value) { 
     var attr = $(this).attr(attrName); 
     if (typeof attr !== 'undefined' && attr !== false)
        result.push($(this));
  });
  return result;
}

As for me, have you considered how the array was populated in the first place? I was in the process of adding MANY objects to an array, and decided to insert each one at the beginning, pushing any existing objects up by one. Requires a mutable array, in this case.

NSMutableArray *myMutableArray = [[NSMutableArray alloc] initWithCapacity:1];
[myMutableArray insertObject:aNewObject atIndex:0];

For my Raspberry Pi 3B model it was

iface lo inet loopback

auto eth0

    wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

If You are looking list of methods which respond by an instance (in your case @current_user). According to ruby documentation methods

Returns a list of the names of public and protected methods of obj. This will include all the methods accessible in obj's ancestors. If the optional parameter is false, it returns an array of obj's public and protected singleton methods, the array will not include methods in modules included in obj.

@current_user.methods
@current_user.methods(false) #only public and protected singleton methods and also array will not include methods in modules included in @current_user class or parent of it.

Alternatively, You can also check that a method is callable on an object or not?.

@current_user.respond_to?:your_method_name

If you don't want parent class methods then just subtract the parent class methods from it.

@current_user.methods - @current_user.class.superclass.new.methods #methods that are available to @current_user instance.

You can unset session variable using:

1. session_unset - Frees all session variables (It is equal to using: $_SESSION = array(); for older deprecated code)
2. unset($_SESSION['Products']); - Unset only Products index in session variable. (Remember: You have to use like a function, not as you used)
3. session_destroy — Destroys all data registered to a session

To know the difference between using session_unset and session_destroy, read this SO answer. That helps.

I guess something like this would do the job.

var option = document.createElement("option");
option.text = "Text";
option.value = "myvalue";
var select = document.getElementById("daySelect");
select.appendChild(option);

import re
for i in range(len(myDict.values())):
     for j in range(len(myDict.values()[i])):
             match=re.search(r'Mary', myDict.values()[i][j])
             if match:
                     print match.group() #Mary
                     print myDict.keys()[i] #firstName
                     print myDict.values()[i][j] #Mary-Ann

Your shell_exec is executed by www-data user, from its directory. You can try

putenv("PATH=/home/user/bin/:" .$_ENV["PATH"]."");

Where your script is located in /home/user/bin Later on you can

$output = "<pre>".shell_exec("scriptname v1 v2")."</pre>";
echo $output;

To display the output of command. (Alternatively, without exporting path, try giving entire path of your script instead of just ./script.sh

As the accepted answer has two important shortfalls, I'm posting the improved answer for those new comers who are looking for a correct answer:

foreach (array_filter(glob('/Path/To/*'), 'is_file') as $file)
{
    // Do something with $file
}

1. Filtering the globe function results with is_file is necessary, because it might return some directories as well.
2. Not all files have a . in their names, so */* pattern sucks in general.

>>> test[:,0]
array([1, 3, 5])

Similarly,

>>> test[1,:]
array([3, 4])

lets you access rows. This is covered in Section 1.4 (Indexing) of the NumPy reference. This is quick, at least in my experience. It's certainly much quicker than accessing each element in a loop.

Since all these tools lack a validation function their outcomes are just drawings and no better tool for creating nice drawings is a piece of paper and pen. Afterwards you can scan your diagrams and insert them into your team's wiki.

You have to disable Globals

 /**

 */

You have many options. Collating some of the answers above and the accepted answer from this post you can do:
1. df[-df["column"].isin(["value"])]
2. df[~df["column"].isin(["value"])]
3. df[df["column"].isin(["value"]) == False]
4. df[np.logical_not(df["column"].isin(["value"]))]

Note: for option 4 for you'll need to import numpy as np

Update: You can also use the .query method for this too. This allows for method chaining:
5. df.query("column not in @values").
where values is a list of the values that you don't want to include.

One is essentially a toy, designed for writing small pieces of code, and traditionally used and abused by inexperienced programmers.

The other is a scripting language for web browsers.

For those who use Angular with the Bootstrap plugin:

http://angular-ui.github.io/bootstrap/#/modal

You can hook into the opened promise of the modal instance:

modalInstance.opened.then(function() {
        $timeout(function() {
            angular.element('#title_input').trigger('focus');
        });
    });

modalInstance.result.then(function ( etc...

It seems to me that everyone answering this question is kind-of missing the one critical issue, except @deceze -- use the right tool for the job. You can force a relational database to store almost any type of data and you can force Mongo to handle relational data, but at what cost? You end up introducing complexity at all levels of development and maintenance, from schema design to application code; not to mention the performance hit.

In 2014 we have access to many database servers that handle specific types of data exceptionally well.

• Mongo (document storage)
• Redis (key-value data storage)
• MySQL/Maria/PostgreSQL/Oracle/etc (relational data)
• CouchDB (JSON)

I'm sure I missed some others, like RabbirMQ and Cassandra. My point is, use the right tool for the data you need to store.

If your application requires storage and retrieval of a variety of data really, really fast, (and who doesn't) don't shy away from using multiple data sources for an application. Most popular web frameworks provide support for multiple data sources (Rails, Django, Grails, Cake, Zend, etc). This strategy limits the complexity to one specific area of the application, the ORM or the application's data source interface.

Just in case this stop working for anyone like me, in OS X, the command key is identified as superso it should be able to do something like this:

[
    {
    "keys": ["super+i"], 
    "command": "reindent", 
    "args": {
        "single_line": 
        false}
    } 
]

in this case using command+i is going to indent your whole code (eclipse like :) )

If you are using Outlook 2010, you can define your own style and select your formatting you want, in the Format options there is one option for Language, here you can specify the language and specify whether you want spell checker to ignore the text with this style.

With this style you can now paste the code as text and select your new style. Outlook will not correct the text and will not perform the spell check on it.

Below is the summary of the style I have defined for emailing the code snippets.

Do not check spelling or grammar, Border:
Box: (Single solid line, Orange,  0.5 pt Line width)
Pattern: Clear (Custom Color(RGB(253,253,217))), Style: Linked, Automatically update, Quick Style

a simple bash script for pretty json printing

json_pretty.sh

#/bin/bash

grep -Eo '"[^"]*" *(: *([0-9]*|"[^"]*")[^{}\["]*|,)?|[^"\]\[\}\{]*|\{|\},?|\[|\],?|[0-9 ]*,?' | awk '{if ($0 ~ /^[}\]]/ ) offset-=4; printf "%*c%s\n", offset, " ", $0; if ($0 ~ /^[{\[]/) offset+=4}'

Example:

cat file.json | json_pretty.sh

The solution that work for me in python 3.6 is the following

py -m pip install Pillow

You need DATE_ADD/DATE_SUB:

AND v.date > (DATE_SUB(CURDATE(), INTERVAL 2 MONTH))
AND v.date < (DATE_SUB(CURDATE(), INTERVAL 1 MONTH))

should work.

There is nothing out there that is going to do this for you; the only way you're going to accomplish this is to iterate all the rows/columns and compare them to each other.

Do you want to insert one dictionary into the other, as one of its elements, or do you want to reference the values of one dictionary from the keys of another?

Previous answers have already covered the first case, where you are creating a dictionary within another dictionary.

To re-reference the values of one dictionary into another, you can use dict.update:

>>> d1 = {1: [1]}
>>> d2 = {2: [2]}
>>> d1.update(d2)
>>> d1
{1: [1], 2: [2]}

A change to a value that's present in both dictionaries will be visible in both:

>>> d1[2].append('appended')
>>> d1
{1: [1], 2: [2, 'appended']}
>>> d2
{2: [2, 'appended']}

This is the same as copying the value over or making a new dictionary with it, i.e.

>>> d3 = {1: d1[1]}
>>> d3[1].append('appended from d3')
>>> d1[1]
[1, 'appended from d3']

Try with the following line:

CleanString = Application.WorksheetFunction.Clean(MyString)

  panel: {
    // ios
    backgroundColor: '#03A9F4',
    alignItems: 'center', 
    shadowOffset: {width: 0, height: 13}, 
    shadowOpacity: 0.3,
    shadowRadius: 6,

    // android (Android +5.0)
    elevation: 3,
  }

or you can use react-native-shadow for android

You can move from one scene to another programmatically using below code :

  let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)

  let objSomeViewController = storyBoard.instantiateViewControllerWithIdentifier(“storyboardID”) as! SomeViewController

  // If you want to push to new ViewController then use this
  self.navigationController?.pushViewController(objSomeViewController, animated: true)

  // ---- OR ----

  // If you want to present the new ViewController then use this
  self.presentViewController(objSomeViewController, animated:true, completion:nil) 

Here storyBoardID is value that you set to scene using Interface Builder. This is shown below :

Here is my solution it is pretty straight forward since all I care about is not necessarily GCD or even accurate ratios: because then you get weird things like 345/113 which are not human comprehensible.

I basically set acceptable landscape, or portrait ratios and their "value" as a float... I then compare my float version of the ratio to each and which ever has the lowest absolute value difference is the ratio closest to the item. That way when the user makes it 16:9 but then removes 10 pixels from the bottom it still counts as 16:9...

accepted_ratios = {
    'landscape': (
        (u'5:4', 1.25),
        (u'4:3', 1.33333333333),
        (u'3:2', 1.5),
        (u'16:10', 1.6),
        (u'5:3', 1.66666666667),
        (u'16:9', 1.77777777778),
        (u'17:9', 1.88888888889),
        (u'21:9', 2.33333333333),
        (u'1:1', 1.0)
    ),
    'portrait': (
        (u'4:5', 0.8),
        (u'3:4', 0.75),
        (u'2:3', 0.66666666667),
        (u'10:16', 0.625),
        (u'3:5', 0.6),
        (u'9:16', 0.5625),
        (u'9:17', 0.5294117647),
        (u'9:21', 0.4285714286),
        (u'1:1', 1.0)
    ),
}


def find_closest_ratio(ratio):
    lowest_diff, best_std = 9999999999, '1:1'
    layout = 'portrait' if ratio < 1.0 else 'landscape'
    for pretty_str, std_ratio in accepted_ratios[layout]:
        diff = abs(std_ratio - ratio)
        if diff < lowest_diff:
            lowest_diff = diff
            best_std = pretty_str
    return best_std


def extract_ratio(width, height):
    try:

You can use one of the many Arrays.binarySearch() methods. Keep in mind that the array must be sorted first.

You can use feather format file. It is extremely fast.

df.to_feather('filename.ft')

The argument associated with the %n will be treated as an int* and is filled with the number of total characters printed at that point in the printf.

The best way to resolve this one is. Download the latest container-selinux package from http://mirror.centos.org/centos/7/extras/x86_64/Packages/ into the VM or the Machine where docker needs to be installed. Error : sometime it will ask for red hat subscription to download from repo. we can do it manually with out subscription as below Run the below command this will install dependencies manually rpm -i container-selinux-2.107-3.el7.noarch.rpm then run the yum install docker-ce

thanks Saa

I have just discovered a way to append text and its working fine at least.

 var text = 'Put any text here';
 $('#text').append(text);

You can change text according to your need.

Hope this helps.

int i = 1;
Test val = static_cast<Test>(i);

You (still) can not choose the position of the column using ALTER TABLE: it can only be added to the end of the table. You can obviously select the columns in any order you want, so unless you are using SELECT * FROM column order shouldn't be a big deal.

If you really must have them in a particular order and you can't drop and recreate the table, then you might be able to drop and recreate columns instead:-

First copy the table

CREATE TABLE my_tab_temp AS SELECT * FROM my_tab;

Then drop columns that you want to be after the column you will insert

ALTER TABLE my_tab DROP COLUMN three;

Now add the new column (two in this example) and the ones you removed.

ALTER TABLE my_tab ADD (two NUMBER(2), three NUMBER(10));

Lastly add back the data for the re-created columns

UPDATE my_tab SET my_tab.three = (SELECT my_tab_temp.three FROM my_tab_temp WHERE my_tab.one = my_tab_temp.one);

Obviously your update will most likely be more complex and you'll have to handle indexes and constraints and won't be able to use this in some cases (LOB columns etc). Plus this is a pretty hideous way to do this - but the table will always exist and you'll end up with the columns in a order you want. But does column order really matter that much?

This worked for me:

body {
  background-image:url(../IMAGES/background.jpg);
  background-position: center center;
  background-repeat: no-repeat;
  background-attachment: fixed;
  background-size: cover;
}

If you are using Bootstrap, look at padding of your tds.

write return(secondmethod) inside of the first method

The answer to many CSS formatting problems seems to be "add another <div>!"

So, in that spirit, have you tried adding a wrapper div to which the border/padding are applied and then putting the 100% width textarea inside of that? Something like (untested):

textarea_x000D_
{_x000D_
  width:100%;_x000D_
}_x000D_
.textwrapper_x000D_
{_x000D_
  border:1px solid #999999;_x000D_
  margin:5px 0;_x000D_
  padding:3px;_x000D_
}

<div style="display: block;" id="rulesformitem" class="formitem">_x000D_
  <label for="rules" id="ruleslabel">Rules:</label>_x000D_
  <div class="textwrapper"><textarea cols="2" rows="10" id="rules"/></div>_x000D_
</div>

The === is not for checking string equalit , to do so you can use the Regxp functions for example

if (x.match(y) === null) {
// x and y are not equal 
}

there is also the test function

SELECT (vg.id, name) FROM v_groups vg 
INNER JOIN people2v_groups p2vg ON vg.id = p2vg.v_group_id
WHERE p2vg.people_id = 0;

Please try this code:-

$url = 'url_to_post';

$data = array("first_name" => "First name","last_name" => "last name","email"=>"[email protected]","addresses" => array ("address1" => "some address" ,"city" => "city","country" => "CA", "first_name" =>  "Mother","last_name" =>  "Lastnameson","phone" => "555-1212", "province" => "ON", "zip" => "123 ABC" ) );

$data_string = json_encode(array("customer" =>$data));

$ch = curl_init($url);

curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$result = curl_exec($ch);

curl_close($ch);

echo "$result";

You can't use a condition to change the structure of your query, just the data involved. You could do this:

update table set
    columnx = (case when condition then 25 else columnx end),
    columny = (case when condition then columny else 25 end)

This is semantically the same, but just bear in mind that both columns will always be updated. This probably won't cause you any problems, but if you have a high transactional volume, then this could cause concurrency issues.

The only way to do specifically what you're asking is to use dynamic SQL. This is, however, something I'd encourage you to stay away from. The solution above will almost certainly be sufficient for what you're after.

In Unix CLI, it's very practical to redirect only errors to a file:

./script 2> errors.log

From your script, either use var_dump() or equivalent as usual (both STDOUT and STDERR will receive the output), but to write only in the log file:

fwrite(STDERR, "Debug infos\n"); // Write in errors.log^

Then from another shell, for live changes:

tail -f errors.log

or simply

watch cat errors.log

And, if you don't want to instantiate Class2, declare UpdateEmployee as static and call it like this:

Class2.UpdateEmployee();

However, you'll normally want to do what @parag said.

To see last commit

git log -1

To see last 2 commit

git log -2

etc....

You can just use nextLine(); as pause

import java.util.Scanner
//
//
Scanner scan = new Scanner(System.in);

void Read()
{
     System.out.print("Press any key to continue . . . ");
     scan.nextLine();
}

However any button you press except Enter means you will have to press Enter after that but I found it better than scan.next();

Here is how to do this on Windows without third-party tools:

1. Import certificate to the certificate store. In Windows Explorer select "Install Certificate" in context menu. Follow the wizard and accept default options "Local User" and "Automatically".

2. Find your certificate in certificate store. On Windows 10 run the "Manage User Certificates" MMC. On Windows 2013 the MMC is called "Certificates". On Windows 10 by default your certificate should be under "Personal"->"Certificates" node.

3. Export Certificate. In context menu select "Export..." menu:

   Select "Yes, export the private key":

   You will see that .PFX option is enabled in this case:

   Specify password for private key.

The schema definition for an attribute determines whether an attribute must have a value. If the manager attribute in the example given is the attribute defined in RFC4524 with OID 0.9.2342.19200300.100.1.10, then that attribute has DN syntax. DN syntax is a sequence of relative distinguished names and must not be empty. The filter given in the example is used to cause the LDAP directory server to return only entries that do not have a manager attribute to the LDAP client in the search result.

You can use counters to do so:

The following style sheet numbers nested list items as "1", "1.1", "1.1.1", etc.

OL { counter-reset: item }
LI { display: block }
LI:before { content: counters(item, ".") " "; counter-increment: item }

Example

ol { counter-reset: item }_x000D_
li{ display: block }_x000D_
li:before { content: counters(item, ".") " "; counter-increment: item }

<ol>_x000D_
  <li>li element_x000D_
    <ol>_x000D_
      <li>sub li element</li>_x000D_
      <li>sub li element</li>_x000D_
      <li>sub li element</li>_x000D_
    </ol>_x000D_
  </li>_x000D_
  <li>li element</li>_x000D_
  <li>li element_x000D_
    <ol>_x000D_
      <li>sub li element</li>_x000D_
      <li>sub li element</li>_x000D_
      <li>sub li element</li>_x000D_
    </ol>_x000D_
  </li>_x000D_
</ol>

See Nested counters and scope for more information.

Here's an explanation I wrote recently to help with the void of information on this attribute. http://www.marklio.com/marklio/PermaLink,guid,ecc34c3c-be44-4422-86b7-900900e451f9.aspx (Internet Archive Wayback Machine link)

To quote the most relevant bits:

[Installing .NET] v4 is “non-impactful”. It should not change the behavior of existing components when installed.

The useLegacyV2RuntimeActivationPolicy attribute basically lets you say, “I have some dependencies on the legacy shim APIs. Please make them work the way they used to with respect to the chosen runtime.”

Why don’t we make this the default behavior? You might argue that this behavior is more compatible, and makes porting code from previous versions much easier. If you’ll recall, this can’t be the default behavior because it would make installation of v4 impactful, which can break existing apps installed on your machine.

The full post explains this in more detail. At RTM, the MSDN docs on this should be better.

The fastest and easiest way is to use .as_matrix(). One short line:

df.iloc[:,[1,2,3]].as_matrix()

Gives:

array([[3, 2, 0.816497],
   [0, 'NaN', 'NaN'],
   [2, 51, 50.0]], dtype=object)

By using indices of the columns, you can use this code for any dataframe with different column names.

Here are the steps for your example:

import pandas as pd
columns = ['viz', 'a1_count', 'a1_mean', 'a1_std']
index = [0,1,2]
vals = {'viz': ['n','n','n'], 'a1_count': [3,0,2], 'a1_mean': [2,'NaN', 51], 'a1_std': [0.816497, 'NaN', 50.000000]}
df = pd.DataFrame(vals, columns=columns, index=index)

Gives:

   viz  a1_count a1_mean    a1_std
0   n         3       2  0.816497
1   n         0     NaN       NaN
2   n         2      51        50

Then:

x1 = df.iloc[:,[1,2,3]].as_matrix()

Gives:

array([[3, 2, 0.816497],
   [0, 'NaN', 'NaN'],
   [2, 51, 50.0]], dtype=object)

Where x1 is numpy.ndarray.

I wrote a function that passes a function when wrapped in any resize event. It uses an interval so that the resize even isn't constantly creating timeout events. This allows it to perform independently of the resize event other than a log entry that should be removed in production.

https://github.com/UniWrighte/resizeOnEnd/blob/master/resizeOnEnd.js

        $(window).resize(function(){
            //call to resizeEnd function to execute function on resize end.
    //can be passed as function name or anonymous function
            resizeEnd(function(){



    });

        });

        //global variables for reference outside of interval
        var interval = null;
        var width = $(window).width();
    var numi = 0; //can be removed in production
        function resizeEnd(functionCall){
            //check for null interval
            if(!interval){
                //set to new interval
                interval = setInterval(function(){
        //get width to compare
                    width2 = $(window).width();
        //if stored width equals new width
                    if(width === width2){
                        //clear interval, set to null, and call passed function
                        clearInterval(interval);
                        interval = null; //precaution
                        functionCall();

                    }
        //set width to compare on next interval after half a second
                    width = $(window).width();
                }, 500);

            }else{
                //logging that should be removed in production
                console.log("function call " + numi++ + " and inteval set skipped");

            }

}

I think this link will be enough for you. I found it when I was searching for the way to execute oracle procedures.

The link to the page

Short Description:

--cursor variable declaration 
variable Out_Ref_Cursor refcursor;
--execute procedure 
execute get_employees_name(IN_Variable,:Out_Ref_Cursor);
--display result referenced by ref cursor.
print Out_Ref_Cursor;

For me its a permissions issue:

On the git server run this command on the repo directory

sudo chmod -R 777 theDirectory/

This is what worked for me...

$('#dialog').live("dialogclose", function(){
   //code to run on dialog close
});

The way I write that loop is:

StringBuilder buff = new StringBuilder();
String sep = "";
for (String str : strs) {
    buff.append(sep);
    buff.append(str);
    sep = ",";
}
return buff.toString();

Don't worry about the performance of sep. An assignment is very fast. Hotspot tends to peel off the first iteration of a loop anyway (as it often has to deal with oddities such as null and mono/bimorphic inlining checks).

If you use it lots (more than once), put it in a shared method.

There is another question on stackoverflow dealing with how to insert a list of ids into an SQL statement.

I don't think you can get it directly, but there are a few ways to find it indirectly.

One way is to use the GC.GetTotalMemory method to measure the amount of memory used before and after creating your object. This won't be perfect, but as long as you control the rest of the application you may get the information you are interested in.

Apart from that you can use a profiler to get the information or you could use the profiling api to get the information in code. But that won't be easy to use I think.

See Find out how much memory is being used by an object in C#? for a similar question.

Use different format or pattern to get the information from the date

var myDate = new Date("2015-06-17 14:24:36");_x000D_
console.log(moment(myDate).format("YYYY-MM-DD HH:mm:ss"));_x000D_
console.log("Date: "+moment(myDate).format("YYYY-MM-DD"));_x000D_
console.log("Year: "+moment(myDate).format("YYYY"));_x000D_
console.log("Month: "+moment(myDate).format("MM"));_x000D_
console.log("Month: "+moment(myDate).format("MMMM"));_x000D_
console.log("Day: "+moment(myDate).format("DD"));_x000D_
console.log("Day: "+moment(myDate).format("dddd"));_x000D_
console.log("Time: "+moment(myDate).format("HH:mm")); // Time in24 hour format_x000D_
console.log("Time: "+moment(myDate).format("hh:mm A"));

If you want a previous version of file, I would recommend using git checkout.

git checkout <commit-hash>

Doing this will send you back in time, it does not affect the current state of your project, you can come to mainline git checkout mainline

but when you add a file in the argument, that file is brought back to you from a previous time to your current project time, i.e. your current project is changed and needs to be committed.

git checkout <commit-hash> -- file_name
git add .
git commit -m 'file brought from previous time'
git push

The advantage of this is that it does not delete history, and neither does revert a particular code changes (git revert)

To minimize the chance of permissions errors, you can configure npm to use a different directory. In this example, you will create and use a hidden directory in your home directory.

Back up your computer. On the command line, in your home directory, create a directory for global installations:

mkdir ~/.npm-global

Configure npm to use the new directory path:

npm config set prefix '~/.npm-global'

In your preferred text editor, open or create a

~/.profile

file and add this line:

export PATH=~/.npm-global/bin:$PATH

On the command line, update your system variables:

source ~/.profile

To test your new configuration, install a package globally without using sudo

Sounds like you want to catch the DocumentCompleted event of your webbrowser control.

MSDN has a couple of good articles about the webbrowser control - WebBrowser Class has lots of examples, and How to: Add Web Browser Capabilities to a Windows Forms Application

I extended Selenium WebDriver implementation, in my case HtmlUnitDriver to expose a method

public boolean isElementPresent(By by){}

like this:

1. check if page is loaded within a timeout period.
2. Once page is loaded, I lower the implicitly wait time of the WebDriver to some milliseconds, in my case 100 mills, probably should work with 0 mills too.
3. call findElements(By), the WebDriver even if will not find the element will wait only the amount of time from above.
4. rise back the implicitly wait time for future page loading

Here is my code:

import java.util.concurrent.TimeUnit;
import org.openqa.selenium.By;
import org.openqa.selenium.JavascriptExecutor;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;
import org.openqa.selenium.support.ui.ExpectedCondition;
import org.openqa.selenium.support.ui.WebDriverWait;

public class CustomHtmlUnitDriver extends HtmlUnitDriver {

    public static final long DEFAULT_TIMEOUT_SECONDS = 30;
    private long timeout = DEFAULT_TIMEOUT_SECONDS;

    public long getTimeout() {
        return timeout;
    }
    public void setTimeout(long timeout) {
        this.timeout = timeout;
    }

    public boolean isElementPresent(By by) {
        boolean isPresent = true;
        waitForLoad();
        //search for elements and check if list is empty
        if (this.findElements(by).isEmpty()) {
            isPresent = false;
        }
        //rise back implicitly wait time
        this.manage().timeouts().implicitlyWait(timeout, TimeUnit.SECONDS);
        return isPresent;
    }

    public void waitForLoad() {
        ExpectedCondition<Boolean> pageLoadCondition = new ExpectedCondition<Boolean>() {
            public Boolean apply(WebDriver wd) {
                //this will tel if page is loaded
                return "complete".equals(((JavascriptExecutor) wd).executeScript("return document.readyState"));
            }
        };
        WebDriverWait wait = new WebDriverWait(this, timeout);
        //wait for page complete
        wait.until(pageLoadCondition);
        //lower implicitly wait time
        this.manage().timeouts().implicitlyWait(100, TimeUnit.MILLISECONDS);
    }   
}

Usage:

CustomHtmlUnitDriver wd = new CustomHtmlUnitDriver();
wd.get("http://example.org");
if (wd.isElementPresent(By.id("Accept"))) {
    wd.findElement(By.id("Accept")).click();
}
else {
    System.out.println("Accept button not found on page");
}

The

<a href="image2.gif" ><img src="image1.gif"/></a>

technique has always worked for me. I used it to good effect in my Super Bowl diary, but I see that the scripts I used are broken. Once I get them fixed I will edit in the URL.

if you're looking for the equivalent of "adb run myapp.apk"

you can use the script shown in this answer

(linux and mac only - maybe with cygwin on windows)

linux/mac users can also create a script to run an apk with something like the following:

create a file named "adb-run.sh" with these 3 lines:

pkg=$(aapt dump badging $1|awk -F" " '/package/ {print $2}'|awk -F"'" '/name=/ {print $2}')
act=$(aapt dump badging $1|awk -F" " '/launchable-activity/ {print $2}'|awk -F"'" '/name=/ {print $2}')
adb shell am start -n $pkg/$act

then "chmod +x adb-run.sh" to make it executable.

now you can simply:

adb-run.sh myapp.apk

The benefit here is that you don't need to know the package name or launchable activity name. Similarly, you can create "adb-uninstall.sh myapp.apk"

Note: This requires that you have aapt in your path. You can find it under the new build tools folder in the SDK

What i did:

I added the following line inside of ROOT/index.jsp

 <meta http-equiv="refresh" content="0;url=/somethingelse/index.jsp"/>

You should call .addAnnotatedClass(Message.class) on your AnnotationConfiguration.

If you want your entities to be auto-discovered, use EntityManager (JPA)

(Reference)

Update: it appears you have listed the class in hibernate.cfg.xml. So auto-discovery is not necessary. Btw, try javax.persistence.Entity

You can not check for version support via command line. Best option would be checking OpenSSL changelog.

Openssl versions till 1.0.0h supports SSLv2, SSLv3 and TLSv1.0. From Openssl 1.0.1 onward support for TLSv1.1 and TLSv1.2 is added.

You can also try this to determine the current global sql_mode value:

SELECT @@GLOBAL.sql_mode;

or session sql_mode value:

SELECT @@SESSION.sql_mode;

I also had the feeling that the SQL mode was indeed empty.

If it's a 3.x version then just simply use:

variantname = input()

For example, you want to input 8:

x = input()
8

x will equal 8 but it's going to be a string except if you define it otherwise.

So you can use the convert command, like:

a = int(x) * 1.1343
print(round(a, 2)) # '9.07'
9.07

I have some experiences in Wamp 3.0 and Apache 2.4 .

After all works do this steps:

1- Disable nod32.

2- Add this line to <VirtualHost *:80> block in httpd-vhosts.conf file:

Require ip 192.168.100 #client ip, allow 192.168.100.### ip's access

I solved the problem. I made mistake in setData(Uri) and setType(String).

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "/download/" + "app.apk")), "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);

That is correct now, my auto-update is working. Thanks for help. =)

Edit 20.7.2016:

After a long time, I had to use this way of updating again in another project. I encountered a number of problems with old solution. A lot of things have changed in that time, so I had to do this with a different approach. Here is the code:

    //get destination to update file and set Uri
    //TODO: First I wanted to store my update .apk file on internal storage for my app but apparently android does not allow you to open and install
    //aplication with existing package from there. So for me, alternative solution is Download directory in external storage. If there is better
    //solution, please inform us in comment
    String destination = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/";
    String fileName = "AppName.apk";
    destination += fileName;
    final Uri uri = Uri.parse("file://" + destination);

    //Delete update file if exists
    File file = new File(destination);
    if (file.exists())
    //file.delete() - test this, I think sometimes it doesnt work
        file.delete();

    //get url of app on server
    String url = Main.this.getString(R.string.update_app_url);

    //set downloadmanager
    DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
    request.setDescription(Main.this.getString(R.string.notification_description));
    request.setTitle(Main.this.getString(R.string.app_name));

    //set destination
    request.setDestinationUri(uri);

    // get download service and enqueue file
    final DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
    final long downloadId = manager.enqueue(request);

    //set BroadcastReceiver to install app when .apk is downloaded
    BroadcastReceiver onComplete = new BroadcastReceiver() {
        public void onReceive(Context ctxt, Intent intent) {
            Intent install = new Intent(Intent.ACTION_VIEW);
            install.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            install.setDataAndType(uri,
                    manager.getMimeTypeForDownloadedFile(downloadId));
            startActivity(install);

            unregisterReceiver(this);
            finish();
        }
    };
    //register receiver for when .apk download is compete
    registerReceiver(onComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));

You can't manipulate :after, because it's not technically part of the DOM and therefore is inaccessible by any JavaScript. But you can add a new class with a new :after specified.

CSS:

.pageMenu .active.changed:after { 
/* this selector is more specific, so it takes precedence over the other :after */
    border-top-width: 22px;
    border-left-width: 22px;
    border-right-width: 22px;
}

JS:

$('.pageMenu .active').toggleClass('changed');

UPDATE: while it's impossible to directly modify the :after content, there are ways to read and/or override it using JavaScript. See "Manipulating CSS pseudo-elements using jQuery (e.g. :before and :after)" for a comprehensive list of techniques.

If you have numerical and categorical both type of data in dataframe You can use : here X is my dataframe having categorical and numerical both variables

from sklearn import preprocessing
le = preprocessing.LabelEncoder()

for i in range(0,X.shape[1]):
    if X.dtypes[i]=='object':
        X[X.columns[i]] = le.fit_transform(X[X.columns[i]])

Note: This technique is good if you are not interested in converting them back.

If you have used chmod command already then check the difference of file, It shows previous file mode and current file mode such as:

new mode : 755

old mode : 644

set old mode of all files using below command

sudo chmod 644 .

now set core.fileMode to false in config file either using command or manually.

git config core.fileMode false

then apply chmod command to change the permissions of all files such as

sudo chmod 755 .

and again set core.fileMode to true.

git config core.fileMode true

For best practises don't Keep core.fileMode false always.

Try this it works for me:

 /^(http[s]?:\/\/){0,1}(w{3,3}\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/;

StringBuilder b = new StringBuilder();

Scanner s = new Scanner(System.in);
String n = s.nextLine();

for(int i = 0; i < n.length(); i++) {
    char c = n.charAt(i);

        b.append(String.valueOf(c).toUpperCase());
    }

}

System.out.println(b);

You can access keys in the App.Config using:

ConfigurationSettings.AppSettings["KeyName"]

At least in Postgres you can use the following statement:

SELECT EntityID, EntityName, EntityProfile IS NOT NULL AS HasProfile FROM Entity

I am not a fan of bumping old articles but because this was one of the first responses for this particular issue I felt a need to clarify something.

As @Bhavin Shah answer states the domain part of the url is case insensitive, so

http://google.com 

and

http://GOOGLE.COM 

and

http://GoOgLe.CoM 

are all the same but everything after the domain name part is considered case sensitive.

so...

http://GOOGLE.COM/ABOUT

and

http://GOOGLE.COM/about

are different.

Note: I am talking "technically" and not "literally" in a lot of cases, most actually, servers are setup to handle these items the same, but it is possible to set them up so they are NOT handled the same.

Different servers handle this differently and in some cases they Have to be case sensitive. In many cases query string values are encoded (such as Session Ids or Base64 encoded data thats passed as a query string value) These items are case sensitive by their nature so the server has to be case sensitive in handling them.

So to answer the question, "should" servers be case sensitive in grabbing this data, the answer is "yes, most definitely."

Of course not everything needs to be case sensitive but the server should be aware of what that is and how to handle those cases.

@Hart Simha's comment basically says the same thing. I missed it before I posted so I want to give credit where credit is due.

I prefer to create queries with SQLAlchemy, and then make a DataFrame from it. SQLAlchemy makes it easier to combine SQL conditions Pythonically if you intend to mix and match things over and over.

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import Table
from sqlalchemy import create_engine
from sqlalchemy.orm import sessionmaker
from pandas import DataFrame
import datetime

# We are connecting to an existing service
engine = create_engine('dialect://user:pwd@host:port/db', echo=False)
Session = sessionmaker(bind=engine)
session = Session()
Base = declarative_base()

# And we want to query an existing table
tablename = Table('tablename', 
    Base.metadata, 
    autoload=True, 
    autoload_with=engine, 
    schema='ownername')

# These are the "Where" parameters, but I could as easily 
# create joins and limit results
us = tablename.c.country_code.in_(['US','MX'])
dc = tablename.c.locn_name.like('%DC%')
dt = tablename.c.arr_date >= datetime.date.today() # Give me convenience or...

q = session.query(tablename).\
            filter(us & dc & dt) # That's where the magic happens!!!

def querydb(query):
    """
    Function to execute query and return DataFrame.
    """
    df = DataFrame(query.all());
    df.columns = [x['name'] for x in query.column_descriptions]
    return df

querydb(q)

I have BaseModel class, so I needed something more generic.

//app/BaseModel.php
public function rules()
{
    return $rules = [];
}
public function isValid($id = '')
{

    $validation = Validator::make($this->attributes, $this->rules($id));

    if($validation->passes()) return true;
    $this->errors = $validation->messages();
    return false;
}

In user class let's suppose I need only email and name to be validated:

//app/User.php
//User extends BaseModel
public function rules($id = '')
{
    $rules = [
                'name' => 'required|min:3',
                'email' => 'required|email|unique:users,email',
                'password' => 'required|alpha_num|between:6,12',
                'password_confirmation' => 'same:password|required|alpha_num|between:6,12',
            ];
    if(!empty($id))
    {
        $rules['email'].= ",$id";
        unset($rules['password']);
        unset($rules['password_confirmation']);
    }

    return $rules;
}

I tested this with phpunit and works fine.

//tests/models/UserTest.php 
public function testUpdateExistingUser()
{
    $user = User::find(1);
    $result = $user->id;
    $this->assertEquals(true, $result);
    $user->name = 'test update';
    $user->email = '[email protected]';
    $user->save();

    $this->assertTrue($user->isValid($user->id), 'Expected to pass');

}

I hope will help someone, even if for getting a better idea. Thanks for sharing yours as well. (tested on Laravel 5.0)

This should work.

 $foo = someFunction 2>$null

If you want to set the image as the background, I've got a solution:

.image {
    background-image: url(yourimage.jpg);
    background-position: center;
}

/*You might be looking something like this?

grep -vn "gloom" `grep -l "loom" ~/projects/**/trunk/src/**/*.@(h|cpp)`

The BACKQUOTES are used like brackets for commands, so in this case with -l enabled, the code in the BACKQUOTES will return you the file names, then with -vn to do what you wanted: have filenames, linenumbers, and also the actual lines.

UPDATE Or with xargs

grep -l "loom" ~/projects/**/trunk/src/**/*.@(h|cpp) | xargs grep -vn "gloom"

Hope that helps.*/

Please ignore what I've written above, it's rubbish.

grep -n "loom" `grep -l "loom" tt4.txt` | grep -v "gloom"

               #this part gets the filenames with "loom"
#this part gets the lines with "loom"
                                          #this part gets the linenumber,
                                          #filename and actual line

use HashSet it's better

take a look here : http://www.dotnetperls.com/hashset

It's a linker error. ld is the linker, so if you get an error message ending with "ld returned 1 exit status", that tells you that it's a linker error.

The error message tells you that none of the object files you're linking against contains a definition for avergecolumns. The reason for that is that the function you've defined is called averagecolumns (in other words: you misspelled the function name when calling the function (and presumably in the header file as well - otherwise you'd have gotten a different error at compile time)).

git checkout -f

This is suffice for your question. Only thing is, once its done, its done. There is no undo.

Just for completion:

I wanted to kill all processes connected to a specific port but not the process listening

the command (in cmd shell) for the port 9001 is:

FOR /F "tokens=5 delims= " %P IN ('netstat -ano ^| findstr -rc:":9001[ ]*ESTA"') DO TaskKill /F /PID %P

findstr:

• r is for expressions and c for exact chain to match.
• [ ]* is for matching spaces

netstat:

• a -> all
• n -> don't resolve (faster)
• o -> pid

It works because netstat prints out the source port then destination port and then ESTABLISHED

one of my application's emails was constantly being tagged as spam. it was html with a single link, which i sent as html in the body with a text/html content type.

my most successful resolution to this problem was to compose the email so it looked like it was generated by an email client.

i changed the email to be a multipart/alternative mime document and i now generate both text/plain and text/html parts.

the email no longer is detected as junk by outlook.

It seems that ARM64 was created by Apple and AARCH64 by the others, most notably GNU/GCC guys.

After some googling I found this link:

The LLVM 64-bit ARM64/AArch64 Back-Ends Have Merged

So it makes sense, iPad calls itself ARM64, as Apple is using LLVM, and Edge uses AARCH64, as Android is using GNU GCC toolchain.

Put both DatePicker and TimePicker in a layout XML.

date_time_picker.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:padding="8dp"
    android:layout_height="match_parent">

    <DatePicker
        android:id="@+id/date_picker"
        android:layout_width="match_parent"
        android:calendarViewShown="true"
        android:spinnersShown="false"
        android:layout_weight="4"
        android:layout_height="0dp" />

    <TimePicker
        android:id="@+id/time_picker"
        android:layout_weight="4"
        android:layout_width="match_parent"
        android:layout_height="0dp" />

    <Button
        android:id="@+id/date_time_set"
        android:layout_weight="1"
        android:layout_width="match_parent"
        android:text="Set"
        android:layout_height="0dp" />

</LinearLayout>

The code:

final View dialogView = View.inflate(activity, R.layout.date_time_picker, null);
final AlertDialog alertDialog = new AlertDialog.Builder(activity).create();

dialogView.findViewById(R.id.date_time_set).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {

         DatePicker datePicker = (DatePicker) dialogView.findViewById(R.id.date_picker);
         TimePicker timePicker = (TimePicker) dialogView.findViewById(R.id.time_picker);

         Calendar calendar = new GregorianCalendar(datePicker.getYear(),
                            datePicker.getMonth(),
                            datePicker.getDayOfMonth(),
                            timePicker.getCurrentHour(),
                            timePicker.getCurrentMinute());

         time = calendar.getTimeInMillis();
         alertDialog.dismiss();
    }});
alertDialog.setView(dialogView);
alertDialog.show();

Yes, there is a better way: You can use the $parse service in your directive to evaluate an expression in the context of the parent scope while binding certain identifiers in the expression to values visible only inside your directive:

$parse(attributes.callback)(scope.$parent, { arg2: yourSecondArgument });

Add this line to the link function of the directive where you can access the directive's attributes.

Your callback attribute may then be set like callback = "callback(item.id, arg2)" because arg2 is bound to yourSecondArgument by the $parse service inside the directive. Directives like ng-click let you access the click event via the $event identifier inside the expression passed to the directive by using exactly this mechanism.

Note that you do not have to make callback a member of your isolated scope with this solution.

Nowadays, animating text color is included in the jQuery UI Effects Core. It's pretty small. You can make a custom download here: http://jqueryui.com/download - but you don't actually need anything but the effects core itself (not even the UI core), and it brings with it different easing functions as well.

Well finding the package when you are connected to internet (repository) is easy however when you only have access to RPM packages inside Redhat or Centos DVD (this happens frequently to me when I have to recover a server and I need an application) I recommend using the commands below which is completely independent of internet and repositories. (supposably you have lots of uninstalled packages in a DVD). Let's say you have mounted Package folder in ~/cent_os_dvd and you are looking for a package that provides "semanage" then you can run:

for file in `find ~/cent_os_dvd/ -iname '*.rpm'`;  do rpm -qlp $file |grep '.*bin/semanage';  if [ $? -eq 0 ]; then echo "is in";echo $file  ; fi;  done

This is a nice way to make use of the virtual DOM:

class Toggle extends React.Component {
  state = {
    show: true,
  }

  toggle = () => this.setState((currentState) => ({show: !currentState.show}));

  render() {
    return (
      <div>
        <button onClick={this.toggle}>
          toggle: {this.state.show ? 'show' : 'hide'}
        </button>    
        {this.state.show && <div>Hi there</div>}
      </div>
     );
  }
}

Example here

Using React hooks:

const Toggle = () => {
  const [show, toggleShow] = React.useState(true);

  return (
    <div>
      <button
        onClick={() => toggleShow(!show)}
      >
        toggle: {show ? 'show' : 'hide'}
      </button>    
      {show && <div>Hi there</div>}
    </div>
  )
}

Example here

For Spring Boot - React js apps I added @CrssOrigin annotation on the controller and it works:

@CrossOrigin(origins = {"http://localhost:3000"})
@RestController
@RequestMapping("/api")

But take care to add localhost correct => 'http://localhost:3000', not with '/' at the end => 'http://localhost:3000/', this was my problem.

If there are no performance gains using a join, then I prefer Common Table Expressions (CTEs) for readability:

WITH subquery AS (
    SELECT address_id, customer, address, partn
    FROM  /* big hairy SQL */ ...
)
UPDATE dummy
SET customer = subquery.customer,
    address  = subquery.address,
    partn    = subquery.partn
FROM subquery
WHERE dummy.address_id = subquery.address_id;

IMHO a bit more modern.

The problem lays here:

--This result set has 3 columns
select LOC_id,LOC_locatie,LOC_deelVan_LOC_id from tblLocatie t
where t.LOC_id = 1 -- 1 represents an example

union all

--This result set has 1 columns   
select t.LOC_locatie + '>' from tblLocatie t
inner join q parent on parent.LOC_id = t.LOC_deelVan_LOC_id

In order to use union or union all number of columns and their types should be identical cross all result sets.

I guess you should just add the column LOC_deelVan_LOC_id to your second result set

1: Add the following line into the AssemblyInfo class

[assembly: log4net.Config.XmlConfigurator(Watch = true)]

2: Make sure you don't use .Net Framework 4 Client Profile as Target Framework (I think this is OK on your side because otherwise it even wouldn't compile)

3: Make sure you log very early in your program. Otherwise, in some scenarios, it will not be initialized properly (read more on log4net FAQ).

So log something during application startup in the Global.asax

public class Global : System.Web.HttpApplication
{
    private static readonly log4net.ILog Log = log4net.LogManager.GetLogger(typeof(Global));
    protected void Application_Start(object sender, EventArgs e)
    {
        Log.Info("Startup application.");
    }
}

4: Make sure you have permission to create files and folders on the given path (if the folder itself also doesn't exist)

5: The rest of your given information looks ok

 <script language="javascript" type="text/javascript">
        function selectFunction() {
             var printStr = document.getElementById("select").options[0].value
            alert(printStr);
            document.getElementById("select").selectedIndex = 0;
        }
    </script>

For this your android application must have uploaded into the android market. when you upload it on the android market then use the following code to open the market with your android application.

    Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("market://details?id=<packagename>"));
startActivity(intent);

If you want it to download and install from your own server then use the following code

Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.example.com/sample/test.apk"));
    startActivity(intent);

Performance wise there is no difference. The only purpose of having const_iterator over iterator is to manage the accessesibility of the container on which the respective iterator runs. You can understand it more clearly with an example:

std::vector<int> integers{ 3, 4, 56, 6, 778 };

If we were to read & write the members of a container we will use iterator:

for( std::vector<int>::iterator it = integers.begin() ; it != integers.end() ; ++it )
       {*it = 4;  std::cout << *it << std::endl; }

If we were to only read the members of the container integers you might wanna use const_iterator which doesn't allow to write or modify members of container.

for( std::vector<int>::const_iterator it = integers.begin() ; it != integers.end() ; ++it )
       { cout << *it << endl; }

NOTE: if you try to modify the content using *it in second case you will get an error because its read-only.

You need text() or html() for label not val() The function should not be called for label instead it is used to get values of input like text or checkbox etc.

Change

value = $("#telefon").val(); 

To

value = $("#telefon").text(); 

curl -iv https://your.domain.io

That will give you cert and header output if you do not wish to use openssl command.

double value = 3.25;
double fractionalPart = value % 1;
double integralPart = value - fractionalPart;

So here's what I did eventually. I hope this helps someone else.

class NoDuplicatesList<E> extends LinkedList<E> {
    @Override
    public boolean add(E e) {
        if (this.contains(e)) {
            return false;
        }
        else {
            return super.add(e);
        }
    }

    @Override
    public boolean addAll(Collection<? extends E> collection) {
        Collection<E> copy = new LinkedList<E>(collection);
        copy.removeAll(this);
        return super.addAll(copy);
    }

    @Override
    public boolean addAll(int index, Collection<? extends E> collection) {
        Collection<E> copy = new LinkedList<E>(collection);
        copy.removeAll(this);
        return super.addAll(index, copy);
    }

    @Override
    public void add(int index, E element) {
        if (this.contains(element)) {
            return;
        }
        else {
            super.add(index, element);
        }
    }
}   

select * into x_history from your_table_here;
truncate table your_table_here;

You can do something like,

RaisedButton.icon( elevation: 4.0,
                    icon: Image.asset('images/image_upload.png' ,width: 20,height: 20,) ,
                      color: Theme.of(context).primaryColor,
                    onPressed: getImage,
                    label: Text("Add Team Image",style: TextStyle(
                        color: Colors.white, fontSize: 16.0))
                  ),

Late, but can be done by using Object.keys like,

var a={key1:'value1',key2:'value2',key3:'value3',key4:'value4'},_x000D_
  ulkeys=document.getElementById('object-keys'),str='';_x000D_
var keys = Object.keys(a);_x000D_
for(i=0,l=keys.length;i<l;i++){_x000D_
   str+= '<li>'+keys[i]+' : '+a[keys[i]]+'</li>';_x000D_
}_x000D_
ulkeys.innerHTML=str;

<ul id="object-keys"></ul>

You can use the Environment class's static NewLine property to get the proper newline:

$errorMsg =  "{0} Error {1}{2} key {3} expected: {4}{5} local value is: {6}" -f `
               (Get-Date),$keyPath,$value,$key,$policyValue,([Environment]::NewLine),$localValue
Add-Content -Path $logpath $errorMsg

HashMap is a Map implementation, allowing duplicate values but not duplicate keys.. For adding an object a Key/Value pair is required. Null Keys and Null values are allowed. eg:

{The->3,world->5,is->2,nice->4}

HashSet is a Set implementation,which does not allow duplicates.If you tried to add a duplicate object, a call to public boolean add(Object o) method, then the set remains unchanged and returns false. eg:

[The,world,is,nice]

I use this... but it requires the user to click on the select box...

Here are the 2 javascript functions

function expand(obj)
{
    obj.size = 5;
}
function unexpand(obj)
{
    obj.size = 1;
}

then i create the select box

<select id="test" multiple="multiple" name="foo" onFocus="expand(this)" onBlur="unexpand(this)">
<option >option1</option>
<option >option2</option>
<option >option3</option>
<option >option4</option>
<option >option5</option>
</select> 

I know this code is a little late, but i hope it helps someone who had the same problem as me.

ps/fyi i have not tested the code above (i create my select box dynamically), and the code i did write was only tested in FireFox.

I find the most valuable feature of .FormulaR1C1 is sheer speed. Versus eg a couple of very large loops filling some data into a sheet, If you can convert what you are doing into a .FormulaR1C1 form. Then a single operation eg myrange.FormulaR1C1 = "my particular formuala" is blindingly fast (can be a thousand times faster). No looping and counting - just fill the range at high speed.

If I understand you correctly, you need to use -SearchBase:

Get-ADUser -SearchBase "OU=Accounts,OU=RootOU,DC=ChildDomain,DC=RootDomain,DC=com" -Filter *

Note that Get-ADUser defaults to using

 -SearchScope Subtree

so you don't need to specify it. It's this that gives you all sub-OUs (and sub-sub-OUs, etc.).

How to find out what this MySQL Error is trying to say:

#1064 - You have an error in your SQL syntax;

This error has no clues in it. You have to double check all of these items to see where your mistake is:

1. You have omitted, or included an unnecessary symbol: !@#$%^&*()-_=+[]{}\|;:'",<>/?
2. A misplaced, missing or unnecessary keyword: select, into, or countless others.
3. You have unicode characters that look like ascii characters in your query but are not recognized.
4. Misplaced, missing or unnecessary whitespace or newlines between keywords.
5. Unmatched single quotes, double quotes, parenthesis or braces.

Take away as much as you can from the broken query until it starts working. And then use PostgreSQL next time that has a sane syntax reporting system.

For Visual Studio 2017, 2019. I got this error and able to fix it just by enable the Live Share extension from extensions.
