This one works for me:

<tr style="height: 15px;"/>

I'm building a React server-side renderer and found this can also occur when building a separate server config from scratch. If you're seeing this error, try the following:

1. Make sure your "entry" value is properly pathed relative to your "context" value. Mine was missing the preceeding "./" before the entry file name.
2. Make sure you have your "resolve" value included. Your imports on anything in node_modules will default to looking in your "context" folder, otherwise.

Example:

const serverConfig = {
name: 'server',
context: path.join(__dirname, 'src'),
entry: {serverEntry: ['./server-entry.js']},
output: {
    path: path.join(__dirname, 'public'),
    filename: 'server.js',
    publicPath: 'public/',
    libraryTarget: 'commonjs2'
},
module: {
    rules: [/*...*/]
},
resolveLoader: {
    modules: [
        path.join(__dirname, 'node_modules')
    ]
},
resolve: {
    modules: [
        path.join(__dirname, 'node_modules')
    ]
}
};

Here, the '\n' left by cin, is creating issues.

do {
    system("cls");
    manageCustomerMenu();
    cin >> choice;               #This cin is leaving a trailing \n
    system("cls");

    switch (choice) {
        case '1':
            createNewCustomer();
            break;

This \n is being consumed by next getline in createNewCustomer(). You should use getline instead -

do {
    system("cls");
    manageCustomerMenu();
    getline(cin, choice)               
    system("cls");

    switch (choice) {
        case '1':
            createNewCustomer();
            break;

I think this would resolve the issue.

You can use regular expression operator (~), separated by (|) as described in Pattern Matching

select column_a from table where column_a ~* 'aaa|bbb|ccc'

Thanks to an answer to Stack Overflow quesion Creating a file name as a timestamp in a batch job, I found that it was a space terminating the filename.

I have written an add-in for SSMS and this problem is fixed there. You can use one of 2 ways:

you can use "Copy current cell 1:1" to copy original cell data to clipboard:

http://www.ssmsboost.com/Features/ssms-add-in-copy-results-grid-cell-contents-line-with-breaks

Or, alternatively, you can open cell contents in external text editor (notepad++ or notepad) using "Cell visualizers" feature: http://www.ssmsboost.com/Features/ssms-add-in-results-grid-visualizers

(feature allows to open contents of field in any external application, so if you know that it is text - you use text editor to open it. If contents is binary data with picture - you select view as picture. Sample below shows opening a picture):

Check to see if the Remote Procedure Call (RPC) service is running. If it is, then it's a firewall issue between your workstation and the server. You can test it by temporary disabling the firewall and retrying the command.

Edit after comment:

Ok, it's a firewall issue. You'll have to either limit the ports WMI/RPC work on, or open a lot of ports in the McAfee firewall.

Here are a few sites that explain this:

1. Microsoft KB for limiting ports
2. McAfee site talking about the same thing

This is what I've got for AS3, don't know much about python but the concept is there

    public function getIntersectingPointF($A:Point, $B:Point, $C:Point, $D:Point):Number {
        var A:Point = $A.clone();
        var B:Point = $B.clone();
        var C:Point = $C.clone();
        var D:Point = $D.clone();
        var f_ab:Number = (D.x - C.x) * (A.y - C.y) - (D.y - C.y) * (A.x - C.x);

        // are lines parallel
        if (f_ab == 0) { return Infinity };

        var f_cd:Number = (B.x - A.x) * (A.y - C.y) - (B.y - A.y) * (A.x - C.x);
        var f_d:Number = (D.y - C.y) * (B.x - A.x) - (D.x - C.x) * (B.y - A.y);
        var f1:Number = f_ab/f_d
        var f2:Number = f_cd / f_d
        if (f1 == Infinity || f1 <= 0 || f1 >= 1) { return Infinity };
        if (f2 == Infinity || f2 <= 0 || f2 >= 1) { return Infinity };
        return f1;
    }

    public function getIntersectingPoint($A:Point, $B:Point, $C:Point, $D:Point):Point
    {
        var f:Number = getIntersectingPointF($A, $B, $C, $D);
        if (f == Infinity || f <= 0 || f >= 1) { return null };

        var retPoint:Point = Point.interpolate($A, $B, 1 - f);
        return retPoint.clone();
    }

using (B a = new B())
{
   DoSomethingWith(a);
}

is equivalent to

B a = new B();
try
{
  DoSomethingWith(a);
}
finally
{
   ((IDisposable)a).Dispose();
}

As mentioned in duscusion: WEB-INF is not really a part of class path. If you use a common template such as maven, use src/main/resources or src/test/resources to place the app-context.xml into. Then you can use 'classpath:'.

Place your config file into src/main/resources/app-context.xml and use code

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:app-context.xml")
public class PersonControllerTest {
...
}

or you can make yout test context with different configuration of beans.

Place your config file into src/test/resources/test-app-context.xml and use code

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:test-app-context.xml")
public class PersonControllerTest {
...
}

<?php
    // Replace with the real server API key from Google APIs
    $apiKey = "your api key";

    // Replace with the real client registration IDs
    $registrationIDs = array( "reg id1","reg id2");

    // Message to be sent
    $message = "hi Shailesh";

    // Set POST variables
    $url = 'https://android.googleapis.com/gcm/send';

    $fields = array(
        'registration_ids' => $registrationIDs,
        'data' => array( "message" => $message ),
    );
    $headers = array(
        'Authorization: key=' . $apiKey,
        'Content-Type: application/json'
    );

    // Open connection
    $ch = curl_init();

    // Set the URL, number of POST vars, POST data
    curl_setopt( $ch, CURLOPT_URL, $url);
    curl_setopt( $ch, CURLOPT_POST, true);
    curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true);
    //curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields));

    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    // curl_setopt($ch, CURLOPT_POST, true);
    // curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode( $fields));

    // Execute post
    $result = curl_exec($ch);

    // Close connection
    curl_close($ch);
    echo $result;

?>

Sometimes it's better to think like a parser, like T-SQL parser. While executing the statement, parser does not have any value in Pivot section and you can't have any check expression in that section. By the way, you can simply use this:

SELECT  CLASS
,   IsNull([AZ], 0)
,   IsNull([CA], 0)
,   IsNull([TX], 0)
    FROM #TEMP
    PIVOT (
        SUM(DATA)
        FOR STATE IN (
            [AZ]
        ,   [CA]
        ,   [TX]
        )
    )   AS  PVT
    ORDER   BY  CLASS

That's an odd approach with isUserAnswer. Are you really going to send all three choices back to the server where it will loop through each one checking for isUserAnswer == true? If so, you can try this:

http://jsfiddle.net/hgxjv/4/

HTML:

<input type="radio" name="response" value="true" ng-click="setChoiceForQuestion(question1, choice)"/>

JavaScript:

$scope.setChoiceForQuestion = function (q, c) {
    angular.forEach(q.choices, function (c) {
        c.isUserAnswer = false;
    });

    c.isUserAnswer = true;
};

Alternatively, I'd recommend changing your tack:

http://jsfiddle.net/hgxjv/5/

<input type="radio" name="response" value="{{choice.id}}" ng-model="question1.userChoiceId"/>

That way you can just send {{question1.userChoiceId}} back to the server.

Arrays in JavaScript don't use strings as keys. You will probably find that the value is there, but the key is an integer.

If you make Dict into an object, this will work:

var dict = {};
var addPair = function (myKey, myValue) {
    dict[myKey] = myValue;
};
var giveValue = function (myKey) {
    return dict[myKey];
};

The myKey variable is already a string, so you don't need more quotes.

Just keep a currentValue variable in your controller that you update on every change. You can then compare that to the new value every time before you update it.'

The idea of using a watch is good as well, but I think a simple variable is the simplest and most logical solution.

This is because your row variable/tuple does not contain any value for that index. You can try printing the whole list like print(row) and check how many indexes there exists.

I found that ev.stopPropagation(); worked for me.

The closest you can do (except for your base-interface approach) is "where T : class", meaning reference-type. There is no syntax to mean "any interface".

This ("where T : class") is used, for example, in WCF to limit clients to service contracts (interfaces).

Step 1:Create a XML File

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


        <ListView
            android:id="@+id/lvItems"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            />
    </LinearLayout>

Step 2:Studnet.java

package com.scancode.acutesoft.telephonymanagerapp;


public class Student
{
    String email,phone,address;

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
}

Step 3:MainActivity.java

 package com.scancode.acutesoft.telephonymanagerapp;

    import android.app.Activity;
    import android.os.Bundle;
    import android.widget.ListView;

    import java.util.ArrayList;

    public class MainActivity extends Activity  {

        ListView lvItems;
        ArrayList<Student> studentArrayList ;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            lvItems = (ListView) findViewById(R.id.lvItems);
            studentArrayList = new ArrayList<Student>();
            dataSaving();
            CustomAdapter adapter = new CustomAdapter(MainActivity.this,studentArrayList);
            lvItems.setAdapter(adapter);
        }

        private void dataSaving() {

            Student student = new Student();
            student.setEmail("[email protected]");
            student.setPhone("1234567890");
            student.setAddress("Hyderabad");
            studentArrayList.add(student);


            student = new Student();
            student.setEmail("[email protected]");
            student.setPhone("1234567890");
            student.setAddress("Banglore");
            studentArrayList.add(student);

            student = new Student();
            student.setEmail("[email protected]");
            student.setPhone("1234567890");
            student.setAddress("Banglore");
            studentArrayList.add(student);

            student = new Student();
            student.setEmail("[email protected]");
            student.setPhone("1234567890");
            student.setAddress("Banglore");
            studentArrayList.add(student);
        }


    }

Step 4:CustomAdapter.java

  package com.scancode.acutesoft.telephonymanagerapp;

    import android.content.Context;
    import android.view.LayoutInflater;
    import android.view.View;
    import android.view.ViewGroup;
    import android.widget.BaseAdapter;
    import android.widget.TextView;

    import java.util.ArrayList;


    public class CustomAdapter extends BaseAdapter
    {
        ArrayList<Student> studentList;
        Context mContext;


        public CustomAdapter(Context context, ArrayList<Student> studentArrayList) {
            this.mContext = context;
            this.studentList = studentArrayList;

        }

        @Override
        public int getCount() {
            return studentList.size();
        }
        @Override
        public Object getItem(int position) {
            return position;
        }

        @Override
        public long getItemId(int position) {
            return position;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {

            Student student = studentList.get(position);
            convertView = LayoutInflater.from(mContext).inflate(R.layout.student_row,null);

            TextView tvStudEmail = (TextView) convertView.findViewById(R.id.tvStudEmail);
            TextView tvStudPhone = (TextView) convertView.findViewById(R.id.tvStudPhone);
            TextView tvStudAddress = (TextView) convertView.findViewById(R.id.tvStudAddress);

            tvStudEmail.setText(student.getEmail());
            tvStudPhone.setText(student.getPhone());
            tvStudAddress.setText(student.getAddress());


            return convertView;
        }
    }

For PHP, Java, C++, C, Perl, JavaScript, CSS you can try:

http://www.prettyprinter.de/index.php

Try:

while [ $stats -gt 300 -o $stats -eq 0 ]

[ is a call to test. It is not just for grouping, like parentheses in other languages. Check man [ or man test for more information.

One other difference lies in the performance.

As the DLL is loaded at runtime by the .exe(s), the .exe(s) and the DLL work with shared memory concept and hence the performance is low relatively to static linking.

On the other hand, a .lib is code that is linked statically at compile time into every process that requests. Hence the .exe(s) will have single memory, thus increasing the performance of the process.

so it's probably not for creating instances of object

It's used exactly for that. You define a function constructor like so:

function Person(name) {
    this.name = name;
}

var john = new Person('John');

However the extra benefit that ECMAScript has is you can extend with the .prototype property, so we can do something like...

Person.prototype.getName = function() { return this.name; }

All objects created from this constructor will now have a getName because of the prototype chain that they have access to.

I always use singular table names but, as already stated, the most important thing is to be consistent and use the same form for all names.

What I don't like about plural table names is that combined names can get quite strange. If for example you have a table named Users and you want to store properties for the user, this would result in a table named UsersProperties...

Put the background url in quotes.

It should be background: url('background.png');

See here for working demo.

You also have an issue with the background-repeat line missing a semicolon in between two statements. If your background is really tiny you won't see it because of that issue.

Just to update on the solution, among the other issues, the background file was being refrenced with .../background.jpg when it should have been ../background.jpg (2 dots, not 3).

You can use Android Material Components.

build.gradle:

implementation 'com.google.android.material:material:1.0.0'

layout.xml:

<com.google.android.material.button.MaterialButtonToggleGroup
        android:id="@+id/toggleGroup"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:checkedButton="@id/btn_one_way"
        app:singleSelection="true">

    <Button
            style="@style/Widget.MaterialComponents.Button.OutlinedButton"
            android:id="@+id/btn_one_way"
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="wrap_content"
            android:text="One way trip" />

    <Button
            style="@style/Widget.MaterialComponents.Button.OutlinedButton"
            android:id="@+id/btn_round"
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="wrap_content"
            android:text="Round trip" />

</com.google.android.material.button.MaterialButtonToggleGroup>

Here is an example if you want to use the primes number to go a lot faster. These lists are easy to find on the internet. I added comments in the code.

You need to pass DateTime object to this func. See manual: php

string date_format ( DateTime $object , string $format )

You can try using:

date_format (new DateTime($time), 'd-m-Y');

Or you can also use:

$date = date_create('2000-01-01');
echo date_format($date, 'Y-m-d H:i:s');

A google search for "python nonlocal" turned up the Proposal, PEP 3104, which fully describes the syntax and reasoning behind the statement. in short, it works in exactly the same way as the global statement, except that it is used to refer to variables that are neither global nor local to the function.

Here's a brief example of what you can do with this. The counter generator can be rewritten to use this so that it looks more like the idioms of languages with closures.

def make_counter():
    count = 0
    def counter():
        nonlocal count
        count += 1
        return count
    return counter

Obviously, you could write this as a generator, like:

def counter_generator():
    count = 0
    while True:
        count += 1
        yield count

But while this is perfectly idiomatic python, it seems that the first version would be a bit more obvious for beginners. Properly using generators, by calling the returned function, is a common point of confusion. The first version explicitly returns a function.

Vim has three modes of operation: Input mode, Command mode & Ex mode.

Input mode - everything that you type, all keystrokes are echoed on the screen.

Command mode or Escape mode - everything that you type in this mode is interpreted as a command.

Ex mode - this is another editor, ex. It is a line editor. It works per line or based on a range of lines. In this mode, a : appears at the bottom of the screen. This is the ex editor.

In order to exit Vim, you can exit while you are in either the ex mode or in the command mode. You cannot exit Vim when you are in input mode.

Exiting from ex mode

1. You need to be sure that you are in the Command mode. To do that, simply press the Esc key.

2. Go to the ex mode by pressing the : key

3. Use any of the following combinations in ex mode to exit:

   :q - quit :q! - quit without saving :wq - save & quit or write & quit :wq! - same as wq, but force write in case file permissions are readonly :x - write & quit :qa - quit all. useful when multiple files are opened like: vim abc.txt xyz.txt

Exiting from command mode

1. Press the escape key. You probably have done this already if you are in command mode.

2. Press capital ZZ (shift zz) - save & exit

3. Press capital ZQ (shift zq) - exit without saving.

type(dict()) says "make a new dict, and then find out what its type is". It's quicker to say just dict. But if you want to just check type, a more idiomatic way is isinstance(x, dict).

Note, that isinstance also includes subclasses (thanks Dustin):

class D(dict):
    pass

d = D()
print("type(d) is dict", type(d) is dict)  # -> False
print("isinstance (d, dict)", isinstance(d, dict))  # -> True

As long as you fix the width of the table itself and set the table-layout property, this is pretty simple :

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <style type="text/css">
        td { width: 30px; overflow: hidden; }
        table { width : 90px; table-layout: fixed; }
    </style>
</head>
<body>

    <table border="2">
        <tr>
            <td>word</td>
            <td>two words</td>
            <td>onereallylongword</td>

        </tr>
    </table>
</body>
</html>

I've tested this in IE6 and 7 and it seems to work fine.

First of all, thanks for guiding me and closing this issue. I found a way to fix this issue from your discussions. Yeah, Let's come to the point. The thing is I'm Using GoogleMapHelper v3 helper in CakePHP3. When i tried to open bootstrap modal popup, I got struck with the grey box issue over the map. It's been extended for 2 days. Finally i got a fix over this.

We need to Update the GoogleMapHelper to fix the issue

Need to add the below script in setCenterMap function

google.maps.event.trigger({$id}, \"resize\");

And need the include below code in JavaScript

google.maps.event.addListenerOnce({$id}, 'idle', function(){
   setCenterMap(new google.maps.LatLng({$this->defaultLatitude}, 
   {$this->defaultLongitude}));
});

Box and Cox (1964) suggested a family of transformations designed to reduce nonnormality of the errors in a linear model. In turns out that in doing this, it often reduces non-linearity as well.

Here is a nice summary of the original work and all the work that's been done since: http://www.ime.usp.br/~abe/lista/pdfm9cJKUmFZp.pdf

You will notice, however, that the log-likelihood function governing the selection of the lambda power transform is dependent on the residual sum of squares of an underlying model (no LaTeX on SO -- see the reference), so no transformation can be applied without a model.

A typical application is as follows:

library(MASS)

# generate some data
set.seed(1)
n <- 100
x <- runif(n, 1, 5)
y <- x^3 + rnorm(n)

# run a linear model
m <- lm(y ~ x)

# run the box-cox transformation
bc <- boxcox(y ~ x)

(lambda <- bc$x[which.max(bc$y)])
[1] 0.4242424

powerTransform <- function(y, lambda1, lambda2 = NULL, method = "boxcox") {

  boxcoxTrans <- function(x, lam1, lam2 = NULL) {

    # if we set lambda2 to zero, it becomes the one parameter transformation
    lam2 <- ifelse(is.null(lam2), 0, lam2)

    if (lam1 == 0L) {
      log(y + lam2)
    } else {
      (((y + lam2)^lam1) - 1) / lam1
    }
  }

  switch(method
         , boxcox = boxcoxTrans(y, lambda1, lambda2)
         , tukey = y^lambda1
  )
}


# re-run with transformation
mnew <- lm(powerTransform(y, lambda) ~ x)

# QQ-plot
op <- par(pty = "s", mfrow = c(1, 2))
qqnorm(m$residuals); qqline(m$residuals)
qqnorm(mnew$residuals); qqline(mnew$residuals)
par(op)

As you can see this is no magic bullet -- only some data can be effectively transformed (usually a lambda less than -2 or greater than 2 is a sign you should not be using the method). As with any statistical method, use with caution before implementing.

To use the two parameter Box-Cox transformation, use the geoR package to find the lambdas:

library("geoR")
bc2 <- boxcoxfit(x, y, lambda2 = TRUE)

lambda1 <- bc2$lambda[1]
lambda2 <- bc2$lambda[2]

EDITS: Conflation of Tukey and Box-Cox implementation as pointed out by @Yui-Shiuan fixed.

@sz3, funny enough today I had to do exactly what you were trying to achieve: 'load a specific CSS file only when a user access' a specific page. So I used the solution above.

But I am here to answer your last question: 'where exactly should I put the code. Any ideas?'

You were right including the code into the resolve, but you need to change a bit the format.

Take a look at the code below:

.when('/home', {
  title:'Home - ' + siteName,
  bodyClass: 'home',
  templateUrl: function(params) {
    return 'views/home.html';
  },
  controler: 'homeCtrl',
  resolve: {
    style : function(){
      /* check if already exists first - note ID used on link element*/
      /* could also track within scope object*/
      if( !angular.element('link#mobile').length){
        angular.element('head').append('<link id="home" href="home.css" rel="stylesheet">');
      }
    }
  }
})

I've just tested and it's working fine, it injects the html and it loads my 'home.css' only when I hit the '/home' route.

Full explanation can be found here, but basically resolve: should get an object in the format

{
  'key' : string or function()
} 

You can name the 'key' anything you like - in my case I called 'style'.

Then for the value you have two options:

• If it's a string, then it is an alias for a service.

• If it's function, then it is injected and the return value is treated as the dependency.

The main point here is that the code inside the function is going to be executed before before the controller is instantiated and the $routeChangeSuccess event is fired.

Hope that helps.

Try if this works:

Panel2.Style.Add("display", "none");

From API 19 onwards you can make use of the Telephony Class for that; Since hardcored values won't retrieve messages in every devices because the content provider Uri changes from devices and manufacturers.

public void getAllSms(Context context) {

    ContentResolver cr = context.getContentResolver();
    Cursor c = cr.query(Telephony.Sms.CONTENT_URI, null, null, null, null);
    int totalSMS = 0;
    if (c != null) {
        totalSMS = c.getCount();
        if (c.moveToFirst()) {
            for (int j = 0; j < totalSMS; j++) {
                String smsDate = c.getString(c.getColumnIndexOrThrow(Telephony.Sms.DATE));
                String number = c.getString(c.getColumnIndexOrThrow(Telephony.Sms.ADDRESS));
                String body = c.getString(c.getColumnIndexOrThrow(Telephony.Sms.BODY));
                Date dateFormat= new Date(Long.valueOf(smsDate));
                String type;
                switch (Integer.parseInt(c.getString(c.getColumnIndexOrThrow(Telephony.Sms.TYPE)))) {
                    case Telephony.Sms.MESSAGE_TYPE_INBOX:
                        type = "inbox";
                        break;
                    case Telephony.Sms.MESSAGE_TYPE_SENT:
                        type = "sent";
                        break;
                    case Telephony.Sms.MESSAGE_TYPE_OUTBOX:
                        type = "outbox";
                        break;
                    default:
                        break;
                }


                c.moveToNext();
            }
        }

        c.close();

    } else {
        Toast.makeText(this, "No message to show!", Toast.LENGTH_SHORT).show();
    }
}

I solved the same issue setting 'laravel/framework' dependency version from "^8.0" to "^7.0".

After that running composer update --ignore-platform-reqs simply worked

You copied using Cells.
If so, no need to PasteSpecial since you are copying data at exactly the same format.
Here's your code with some fixes.

Dim x As Workbook, y As Workbook
Dim ws1 As Worksheet, ws2 As Worksheet

Set x = Workbooks.Open("path to copying book")
Set y = Workbooks.Open("path to pasting book")

Set ws1 = x.Sheets("Sheet you want to copy from")
Set ws2 = y.Sheets("Sheet you want to copy to")

ws1.Cells.Copy ws2.cells
y.Close True
x.Close False

If however you really want to paste special, use a dynamic Range("Address") to copy from.
Like this:

ws1.Range("Address").Copy: ws2.Range("A1").PasteSpecial xlPasteValues
y.Close True
x.Close False

Take note of the : colon after the .Copy which is a Statement Separating character.
Using Object.PasteSpecial requires to be executed in a new line.
Hope this gets you going.

For the case of a string delimiter (not for the char case, as the subject says):
string source = "@@@once@@@upon@@@a@@@time@@@";
int count = source.Split(new[] { "@@@" }, StringSplitOptions.RemoveEmptyEntries).Length - 1;

The poster's original source value's ("/once/upon/a/time/") natural delimiter is a char '/' and responses do explain source.Split(char[]) option though...

I created a fiddle to replace the broken image using "onerror" event. This may help you.

    //the placeholder image url
    var defaultUrl = "url('https://sadasd/image02.png')";

    $('div').each(function(index, item) {
      var currentUrl = $(item).css("background-image").replace(/^url\(['"](.+)['"]\)/, '$1');
      $('<img>', {
        src: currentUrl
      }).on("error", function(e) {
        $this = $(this);
        $this.css({
          "background-image": defaultUrl
        })
        e.target.remove()
      }.bind(this))
    })

There are 2 ways of doing this

foreach($questions as $key => $question){
    $questions[$key]['answers'] = $answers_model->get_answers_by_question_id($question['question_id']);
}

This way you save the key, so you can update it again in the main $questions variable

or

foreach($questions as &$question){

Adding the & will keep the $questions updated. But I would say the first one is recommended even though this is shorter (see comment by Paystey)

Per the PHP foreach documentation:

In order to be able to directly modify array elements within the loop precede $value with &. In that case the value will be assigned by reference.

Use for...in loop:

for (var key in obj) {
   console.log(' name=' + key + ' value=' + obj[key]);

   // do some more stuff with obj[key]
}

You have not included Launcher intent filter in activity you want to appear first, so it does not know which activity to start when application launches, for this tell the system by including launcher filter intent in manifest.xml

Firstly,the crash reason is decorView's index is -1,we can knew it from Android source code ,there is code snippet:

class:android.view.WindowManagerGlobal

file:WindowManagerGlobal.java

private int findViewLocked(View view, boolean required) {
        final int index = mViews.indexOf(view);
//here, view is decorView,comment by OF
        if (required && index < 0) {
            throw new IllegalArgumentException("View=" + view + " not attached to window manager");
        }
        return index;
    }

so we get follow resolution,just judge decorView's index,if it more than 0 then continue or just return and give up dismiss,code as follow:

try {
            Class<?> windowMgrGloable = Class.forName("android.view.WindowManagerGlobal");
            try {
                Method mtdGetIntance = windowMgrGloable.getDeclaredMethod("getInstance");
                mtdGetIntance.setAccessible(true);
                try {
                    Object windownGlobal = mtdGetIntance.invoke(null,null);
                    try {
                        Field mViewField = windowMgrGloable.getDeclaredField("mViews");
                        mViewField.setAccessible(true);
                        ArrayList<View> mViews = (ArrayList<View>) mViewField.get(windownGlobal);
                        int decorViewIndex = mViews.indexOf(pd.getWindow().getDecorView());
                        Log.i(TAG,"check index:"+decorViewIndex);
                        if (decorViewIndex < 0) {
                            return;
                        }
                    } catch (NoSuchFieldException e) {
                        e.printStackTrace();
                    }
                } catch (IllegalAccessException e) {
                    e.printStackTrace();
                } catch (InvocationTargetException e) {
                    e.printStackTrace();
                }
            } catch (NoSuchMethodException e) {
                e.printStackTrace();
            }
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
        if (pd.isShowing()) {
            pd.dismiss();
        }

Just declare a method,e.g:if ur button id is button1 then,

button1.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Toast.makeText(Context, "Hello", Toast.LENGTH_SHORT).show();
        }
    });

If you want to make the imageview1 visible then in that method write:

imageview1.setVisibility(ImageView.VISIBLE);

It depends on the Test Construct around the operator. Your options are double parentheses, double brackets, single brackets, or test.

If you use ((…)), you are testing arithmetic equality with == as in C:

$ (( 1==1 )); echo $?
0
$ (( 1==2 )); echo $?
1

(Note: 0 means true in the Unix sense and a failed test results in a non-zero number.)

Using -eq inside of double parentheses is a syntax error.

If you are using […] (or single brackets) or [[…]] (or double brackets), or test you can use one of -eq, -ne, -lt, -le, -gt, or -ge as an arithmetic comparison.

$ [ 1 -eq 1 ]; echo $?
0
$ [ 1 -eq 2 ]; echo $?
1
$ test 1 -eq 1; echo $?
0

The == inside of single or double brackets (or the test command) is one of the string comparison operators:

$ [[ "abc" == "abc" ]]; echo $?
0
$ [[ "abc" == "ABC" ]]; echo $?
1

As a string operator, = is equivalent to ==. Also, note the whitespace around = or ==: it’s required.

While you can do [[ 1 == 1 ]] or [[ $(( 1+1 )) == 2 ]] it is testing the string equality — not the arithmetic equality.

So -eq produces the result probably expected that the integer value of 1+1 is equal to 2 even though the right-hand side is a string and has a trailing space:

$ [[ $(( 1+1 )) -eq  "2 " ]]; echo $?
0

While a string comparison of the same picks up the trailing space and therefore the string comparison fails:

$ [[ $(( 1+1 )) == "2 " ]]; echo $?
1

And a mistaken string comparison can produce a completely wrong answer. 10 is lexicographically less than 2, so a string comparison returns true or 0. So many are bitten by this bug:

$ [[ 10 < 2 ]]; echo $?
0

The correct test for 10 being arithmetically less than 2 is this:

$ [[ 10 -lt 2 ]]; echo $?
1

In comments, there is a question about the technical reason why using the integer -eq on strings returns true for strings that are not the same:

$ [[ "yes" -eq "no" ]]; echo $?
0

The reason is that Bash is untyped. The -eq causes the strings to be interpreted as integers if possible including base conversion:

$ [[ "0x10" -eq 16 ]]; echo $?
0
$ [[ "010" -eq 8 ]]; echo $?
0
$ [[ "100" -eq 100 ]]; echo $?
0

And 0 if Bash thinks it is just a string:

$ [[ "yes" -eq 0 ]]; echo $?
0
$ [[ "yes" -eq 1 ]]; echo $?
1

So [[ "yes" -eq "no" ]] is equivalent to [[ 0 -eq 0 ]]

Last note: Many of the Bash specific extensions to the Test Constructs are not POSIX and therefore may fail in other shells. Other shells generally do not support [[...]] and ((...)) or ==.

You can simply use String.Join function, and as separator use string.Empty because it uses StringBuilder internally.

string result = string.Join(string.Empty, new []{0,1,2,3,0,1});

E.g.: If you use semicolon as separator, the result would be 0;1;2;3;0;1.

It actually works with null separator, and second parameter can be enumerable of any objects, like:

string result = string.Join(null, new object[]{0,1,2,3,0,"A",DateTime.Now});

To save you some time here is the answer from a link in a previous answer at https://forums.asp.net/t/1448398.aspx

ActionResult is an abstract class, and it's base class for ViewResult class.

In MVC framework, it uses ActionResult class to reference the object your action method returns. And invokes ExecuteResult method on it.

And ViewResult is an implementation for this abstract class. It will try to find a view page (usually aspx page) in some predefined paths(/views/controllername/, /views/shared/, etc) by the given view name.

It's usually a good practice to have your method return a more specific class. So if you are sure that your action method will return some view page, you can use ViewResult. But if your action method may have different behavior, like either render a view or perform a redirection. You can use the more general base class ActionResult as the return type.

import matplotlib.pyplot as plt

Using 'matplotlib.pyplot.imread' is recommended by warning messages in jupyter.

I have routine in VB ..

but you should have 2 pictureboxes .. 1 for frame .. 1 for the image .. and it make keep the picture's size ratio

Assumed picFrame is the image frame and picImg is the image

Sub InsertPicture(ByVal oImg As Image)
    Dim oFoto As Image
    Dim x, y As Integer

    oFoto = oImg
    picImg.Visible = False
    picImg.Width = picFrame.Width - 2
    picImg.Height = picFrame.Height - 2
    picImg.Location = New Point(1, 1)
    SetPicture(picPreview, oFoto)
    x = (picImg.Width - picFrame.Width) / 2
    y = (picImg.Height - picFrame.Height) / 2
    picImg.Location = New Point(x, y)
    picImg.Visible = True

End Sub

I'm sure you can make it as C# ....

In addition to 2 mechanisms already mentioned, there is also global feature that can be used to suppress all failures caused by unknown (unmapped) properties:

// jackson 1.9 and before
objectMapper.configure(DeserializationConfig.Feature.FAIL_ON_UNKNOWN_PROPERTIES, false);
// or jackson 2.0
objectMapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

This is the default used in absence of annotations, and can be convenient fallback.

The application/x-www-form-urlencoded Content-type header is not needed. Unless the request handler expects the parameters coming from request body. Try it out:

curl -X DELETE "http://localhost:5000/locations?id=3"

or

curl -X GET "http://localhost:5000/locations?id=3"

WITHOUT clicking the button you will have to listen to the change event of the input fields

var confirmField = document.getElementById("confirm_password");
var passwordField = document.getElementById("password");

function checkPasswordMatch(){
    var status = document.getElementById("password_status");
    var submit = document.getElementById("submit");

    status.innerHTML = "";
    submit.removeAttribute("disabled");

    if(confirmField.value === "")
        return;

    if(passwordField.value === confirmField.value)
        return;

    status.innerHTML = "Passwords don't match";
    submit.setAttribute("disabled", "disabled");
}

passWordField.addEventListener("change", function(event){
    checkPasswordMatch();
});
confirmField.addEventListener("change", function(event){
    checkPasswordMatch();
});

then add the status element to your html:

<p id="password_status"></p>

and set the submit button id to submit

... id="submit" />

hope this helps you

Yes. This error is a structured exception that wasn't mapped into a .NET error. It's probably your DataGrid mapping throwing a native exception that was uncaught.

You can tell what exception is occurring by looking at the ExternalException.ErrorCode property. I'd check your stack trace, and if it's tied to the DevExpress grid, report the problem to them.

You are missing a parameter in the command. It should be in this order:

composer create-project [PACKAGE] [DESTINATION PATH] [--FLAGS]

You're mistakingly specifying your local path as the Composer/Packagist package you wish to create a project from. Hence the "Could not find package" message.

Simply make sure you're specifying the Laravel package and you should be good to go:

composer create-project laravel/laravel /Applications/MAMP/htdocs/test_laravel

addslashes() isn't fully adequate, but PHP's mssql package doesn't provide any decent alternative. The ugly but fully general solution is encoding the data as a hex bytestring, i.e.

$unpacked = unpack('H*hex', $data);
mssql_query('
    INSERT INTO sometable (somecolumn)
    VALUES (0x' . $unpacked['hex'] . ')
');

Abstracted, that would be:

function mssql_escape($data) {
    if(is_numeric($data))
        return $data;
    $unpacked = unpack('H*hex', $data);
    return '0x' . $unpacked['hex'];
}

mssql_query('
    INSERT INTO sometable (somecolumn)
    VALUES (' . mssql_escape($somevalue) . ')
');

mysql_error() equivalent is mssql_get_last_message().

This answer has 20 upvotes now, but it is not intended as an endorsement of std::valarray.

In my experience, time is better spent installing and learning to use a full-fledged math library such as Eigen. Valarray has fewer features than the competition, but it isn't more efficient or particularly easier to use.

If you only need a little bit of linear algebra, and you are dead-set against adding anything to your toolchain, then maybe valarray would fit. But, being stuck unable to express the mathematically correct solution to your problem is a very bad position to be in. Math is relentless and unforgiving. Use the right tool for the job.

The standard library provides std::valarray<double>. std::vector<>, suggested by a few others here, is intended as a general-purpose container for objects. valarray, lesser known because it is more specialized (not using "specialized" as the C++ term), has several advantages:

• It does not allocate extra space. A vector rounds up to the nearest power of two when allocating, so you can resize it without reallocating every time. (You can still resize a valarray; it's just still as expensive as realloc().)
• You may slice it to access rows and columns easily.
• Arithmetic operators work as you would expect.

Of course, the advantage over using C is that you don't need to manage memory. The dimensions can reside on the stack, or in a slice object.

std::valarray<double> matrix( row * col ); // no more, no less, than a matrix
matrix[ std::slice( 2, col, row ) ] = pi; // set third column to pi
matrix[ std::slice( 3*row, row, 1 ) ] = e; // set fourth row to e

How about this?

Stick this in your ~/.vimrc and be happy:

" enables :Paste to just do what you want
command Paste execute 'set noai | insert | set ai'

Edit: on reflection, :r !cat is a far better approach since it's short, semantic, and requires no custom vimrc. Use that instead!

Add the css:

   html,body{
        height:100%;
        }
    .bg-img {
        background: url(image.jpg) no-repeat center top; 
        background-size: cover; 
        height:100%;     
    }

And html is:

<div class="bg-mg"></div>

CSS: stretching background image to 100% width and height of screen?

You can do this in 3 easy steps:

1)Suppose we have a matrix

   1 2 3
   4 5 6
   7 8 9

2)Take the transpose of the matrix

   1 4 7
   2 5 8
   3 6 9

3)Interchange rows to get rotated matrix

   3 6 9
   2 5 8
   1 4 7

Java source code for this:

public class MyClass {

    public static void main(String args[]) {
        Demo obj = new Demo();
        /*initial matrix to rotate*/
        int[][] matrix = { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } };
        int[][] transpose = new int[3][3]; // matrix to store transpose

        obj.display(matrix);              // initial matrix

        obj.rotate(matrix, transpose);    // call rotate method
        System.out.println();
        obj.display(transpose);           // display the rotated matix
    }
}

class Demo {   
    public void rotate(int[][] mat, int[][] tran) {

        /* First take the transpose of the matrix */
        for (int i = 0; i < mat.length; i++) {
            for (int j = 0; j < mat.length; j++) {
                tran[i][j] = mat[j][i]; 
            }
        }

        /*
         * Interchange the rows of the transpose matrix to get rotated
         * matrix
         */
        for (int i = 0, j = tran.length - 1; i != j; i++, j--) {
            for (int k = 0; k < tran.length; k++) {
                swap(i, k, j, k, tran);
            }
        }
    }

    public void swap(int a, int b, int c, int d, int[][] arr) {
        int temp = arr[a][b];
        arr[a][b] = arr[c][d];
        arr[c][d] = temp;    
    }

    /* Method to display the matrix */
    public void display(int[][] arr) {
        for (int i = 0; i < arr.length; i++) {
            for (int j = 0; j < arr.length; j++) {
                System.out.print(arr[i][j] + " ");
            }
            System.out.println();
        }
    }
}

Output:

1 2 3 
4 5 6 
7 8 9 

3 6 9 
2 5 8 
1 4 7 

void myfunc(void)
{
    char* text = "Hello World";
    char  aLetter = 'C';

    printf("%s\n", text);
    printf("%c\n", aLetter);
}

The event when user releases his finger is MotionEvent.ACTION_UP. I'm not aware if there are any guidelines which prohibit using View.OnTouchListener instead of onClick(), most probably it depends of situation.

Here's a sample code:

imageButton.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_UP){

            // Do what you want
            return true;
        }
        return false;
    }
});

Based on your replies to everyone else, something like this is what you're looking for.

string file = @"C:\file.txt";
string strToProcess = "fkdfdsfdflkdkfk@dfsdfjk72388389@kdkfkdfkkl@jkdjkfjd@jjjk@";
string[] lines = strToProcess.Split(new char[] { '@' }, StringSplitOptions.RemoveEmptyEntries);

using (StreamWriter writer = new StreamWriter(file))
{
    foreach (string line in lines)
    {
        writer.WriteLine(line + "@");
    }
}

1) Right Click on **Solution Explorer**
2) Go to the **Properties** 
3) Expand **Common Properties**
4) Select **Start Up Project**
5) click the radio button (**Single Start_up Project**)
6) select your Project name 
7) Then Debug Your project

I don't think the problem lies in the sample you posted - we'd need to see the CSS, or verify its location etc!

But why not try stripping it down to one CSS rule - put it in the HEAD section, then if it works, move that rule to the external file. Then re-introduce the other rules to make sure there's nothing missing or taking precedence over your CSS.

I've had this happen when launching an ASP.NET website in 2013. It appears that in my case it goes away once the web browser completely launches.

From the side of ZIP archive structure - you can update zip file without recompressing it, you will just need to skip all files which are prior of the file you need to replace, then put your updated file, and then the rest of the files. And finally you'll need to put the updated centeral directory structure. However, I doubt that most common tools would allow you to make this.

There are a lot of very nice answers on this page and I googled for some more, but none of the answers ticked all the checkboxes on my wish list:

• CSS only, no Javascript
• Stick to Tom Kenny's Best Design Practices
• Layout like the other answers
• Each step has a name and a number
• Responsive layout: font size independent
• Fluid layout: the list and its items scale with the available width
• The names and numbers are centered in their block
• The "done" color goes up to and including the active item, but not past it.
• The active item should stand out graphically

So I mixed the code of several examples, fixed the things that I needed and here is the result:

I used the following CSS and HTML:

        <span class="step"><span>4</span></span>_x000D_

</ol>

As can be seen in the example above, there are now two list item classes to take note of: active and done. Use class="active" for the current step, use class="done" for all steps before it.

Also note the data-steps="4" in the ol tag; set this to the total number of steps to apply the correct size to all list items.

Feel free to play around with the JSFiddle. Enjoy!

Here is another answer (and personally I think it's more appropriate)

var currentDate = new Date(); 
currentDate = JSON.stringify(currentDate);

// Now currentDate is in a different format... oh gosh what do we do...

currentDate = new Date(JSON.parse(currentDate));

// Now currentDate is back to its original form :)

Although there are some useful algorithmic explanations here, I think it may help to add some simple 'real life' reasoning as to why it works this way, which I have found useful when introducing the subject to young newcomers:

With something like 'range(1,10)' confusion can arise from thinking that pair of parameters represents the "start and end".

It is actually start and "stop".

Now, if it were the "end" value then, yes, you might expect that number would be included as the final entry in the sequence. But it is not the "end".

Others mistakenly call that parameter "count" because if you only ever use 'range(n)' then it does, of course, iterate 'n' times. This logic breaks down when you add the start parameter.

So the key point is to remember its name: "stop". That means it is the point at which, when reached, iteration will stop immediately. Not after that point.

So, while "start" does indeed represent the first value to be included, on reaching the "stop" value it 'breaks' rather than continuing to process 'that one as well' before stopping.

One analogy that I have used in explaining this to kids is that, ironically, it is better behaved than kids! It doesn't stop after it supposed to - it stops immediately without finishing what it was doing. (They get this ;) )

Another analogy - when you drive a car you don't pass a stop/yield/'give way' sign and end up with it sitting somewhere next to, or behind, your car. Technically you still haven't reached it when you do stop. It is not included in the 'things you passed on your journey'.

I hope some of that helps in explaining to Pythonitos/Pythonitas!

'b' should be in capital letter in document.getElementById modified code jsfiddle

function test()
{

var element = document.createElement("div");
element.appendChild(document.createTextNode('The man who mistook his wife for a hat'));
document.getElementById('lc').appendChild(element);
 //document.body.appendChild(element);
 }

For the allowed characters you can use

^[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$

to validate a complete string that should consist of only allowed characters. Note that - is at the end (because otherwise it'd be a range) and a few characters are escaped.

For the invalid characters you can use

[<>'"/;`%]

to check for them.

To combine both into a single regex you can use

^(?=[a-zA-Z0-9~@#$^*()_+=[\]{}|\\,.?: -]*$)(?!.*[<>'"/;`%])

but you'd need a regex engine that allows lookahead.

You can write as you show in example, but than you get build-error.

For fix this:

1. print app.url_map () in you root .py
2. you see something like:

<Rule '/<userId>/<username>' (HEAD, POST, OPTIONS, GET) -> user.show_0>

and

<Rule '/<userId>' (HEAD, POST, OPTIONS, GET) -> .show_1>

3. than in template you can {{ url_for('.show_0', args) }} and {{ url_for('.show_1', args) }}

The <a>nchor element is simply an anchor to or from some content. Originally the HTML specification allowed for named anchors (<a name="foo">) and linked anchors (<a href="#foo">).

The named anchor format is less commonly used, as the fragment identifier is now used to specify an [id] attribute (although for backwards compatibility you can still specify [name] attributes). An <a> element without an [href] attribute is still valid.

As far as semantics and styling is concerned, the <a> element isn't a link (:link) unless it has an [href] attribute. A side-effect of this is that an <a> element without [href] won't be in the tabbing order by default.

The real question is whether the <a> element alone is an appropriate representation of a <button>. On a semantic level, there is a distinct difference between a link and a button.

A button is something that when clicked causes an action to occur.

A link is a button that causes a change in navigation in the current document. The navigation that occurs could be moving within the document in the case of fragment identifiers (#foo) or moving to a new document in the case of urls (/bar).

As links are a special type of button, they have often had their actions overridden to perform alternative functions. Continuing to use an anchor as a button is ok from a consistency standpoint, although it's not quite accurate semantically.

If you're concerned about the semantics and accessibility of using an <a> element (or <span>, or <div>) as a button, you should add the following attributes:

<a role="button" tabindex="0" ...>...</a>

The button role tells the user that the particular element is being treated as a button as an override for whatever semantics the underlying element may have had.

For <span> and <div> elements, you may want to add JavaScript key listeners for Space or Enter to trigger the click event. <a href> and <button> elements do this by default, but non-button elements do not. Sometimes it makes more sense to bind the click trigger to a different key. For example, a "help" button in a web app might be bound to F1.

$('#datetimepicker').datetimepicker({ 
    minView: 2, 
    pickTime: false, 
    language: 'pt-BR' 
});

Please try if it works for you as well

Using the client manager affects all connections or sets a client machine specific alias.

Use the comma as above: this can be used in an app.config too

It's probably needed if you have firewalls between you and the server too...

Using just scipy, glob and having PIL installed (pip install pillow) you can use scipy's imread method:

from scipy import misc
import glob

for image_path in glob.glob("/home/adam/*.png"):
    image = misc.imread(image_path)
    print image.shape
    print image.dtype

UPDATE

According to the doc, scipy.misc.imread is deprecated starting SciPy 1.0.0, and will be removed in 1.2.0. Consider using imageio.imread instead. See the answer by Charles.

Case 1: Insert Row and Query Foreign Key

Here is an alternate syntax I use:

INSERT INTO tab_student 
   SET name_student = 'Bobby Tables',
       id_teacher_fk = (
       SELECT id_teacher
         FROM tab_teacher
        WHERE name_teacher = 'Dr. Smith')

I'm doing this in Excel to import a pivot table to a dimension table and a fact table in SQL so you can import to both department and expenses tables from the following:

Case 2: Insert Row and Then Insert Dependant Row

Luckily, MySQL supports LAST_INSERT_ID() exactly for this purpose.

INSERT INTO tab_teacher
   SET name_teacher = 'Dr. Smith';
INSERT INTO tab_student 
   SET name_student = 'Bobby Tables',
       id_teacher_fk = LAST_INSERT_ID()

Copy and paste this code into your Activity and when it is executed it will Toast the device's screen size category.

int screenSize = getResources().getConfiguration().screenLayout &
        Configuration.SCREENLAYOUT_SIZE_MASK;

String toastMsg;
switch(screenSize) {
    case Configuration.SCREENLAYOUT_SIZE_LARGE:
        toastMsg = "Large screen";
        break;
    case Configuration.SCREENLAYOUT_SIZE_NORMAL:
        toastMsg = "Normal screen";
        break;
    case Configuration.SCREENLAYOUT_SIZE_SMALL:
        toastMsg = "Small screen";
        break;
    default:
        toastMsg = "Screen size is neither large, normal or small";
}
Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();

It's not possible to achieve the required level of control over presentation in a regular textarea.

If you're OK with that, try CodeMirror or Ace or Monaco (used in MS VSCode).

From the duplicate thread - an obligatory wikipedia link: Comparison of JavaScript-based source code editors

Ruby 2.7+

There is now!

Ruby 2.7 is introducing filter_map for this exact purpose. It's idiomatic and performant, and I'd expect it to become the norm very soon.

For example:

numbers = [1, 2, 5, 8, 10, 13]
enum.filter_map { |i| i * 2 if i.even? }
# => [4, 16, 20]

In your case, as the block evaluates to falsey, simply:

items.filter_map { |x| process_x url }

"Ruby 2.7 adds Enumerable#filter_map" is a good read on the subject, with some performance benchmarks against some of the earlier approaches to this problem:

N = 100_000
enum = 1.upto(1_000)
Benchmark.bmbm do |x|
  x.report("select + map")  { N.times { enum.select { |i| i.even? }.map{ |i| i + 1 } } }
  x.report("map + compact") { N.times { enum.map { |i| i + 1 if i.even? }.compact } }
  x.report("filter_map")    { N.times { enum.filter_map { |i| i + 1 if i.even? } } }
end

What's wrong with using two regexs (or three)? This makes your intentions more clear and may even improve your performance:

if ($string =~ /^(Clinton|Reagan)/i && $string !~ /Bush/i) { ... }

if (($string =~ /^Clinton/i || $string =~ /^Reagan/i)
        && $string !~ /Bush/i) {
    print "$string\n"
}

Some operations in Excel are limited by available Memory. If you repeat the same process over and over it could produce a memory overflow and excel will not be able to repeat it anymore. This happened to me while trying to create several sheets in the same workbook.

dat <- data.frame(x1 = c(1,2,3, NA, 5), x2 = c(100, NA, 300, 400, 500))

na.omit(dat)
  x1  x2
1  1 100
3  3 300
5  5 500

Unfortunatelly, Ajax events are poorly documented and I haven't found any comprehensive list. For example, User Guide v. 3.5 lists itemChange event for p:autoComplete, but forgets to mention change event.

If you want to find out which events are supported:

1. Download and unpack primefaces source jar
2. Find the JavaScript file, where your component is defined (for example, most form components such as SelectOneMenu are defined in forms.js)
3. Search for this.cfg.behaviors references

For example, this section is responsible for launching toggleSelect event in SelectCheckboxMenu component:

fireToggleSelectEvent: function(checked) {
    if(this.cfg.behaviors) {
        var toggleSelectBehavior = this.cfg.behaviors['toggleSelect'];

        if(toggleSelectBehavior) {
            var ext = {
                params: [{name: this.id + '_checked', value: checked}]
            }
        }

        toggleSelectBehavior.call(this, null, ext);
    }
},

The answer above suggests changing the function to echo data rather than return it so that it can be captured.

For a function or program that you can't modify where the return value needs to be saved to a variable (like test/[, which returns a 0/1 success value), echo $? within the command substitution:

# Test if we're remote.
isRemote="$(test -z "$REMOTE_ADDR"; echo $?)"
# Or:
isRemote="$([ -z "$REMOTE_ADDR" ]; echo $?)"

# Additionally you may want to reverse the 0 (success) / 1 (error) values
# for your own sanity, using arithmetic expansion:
remoteAddrIsEmpty="$([ -z "$REMOTE_ADDR" ]; echo $((1-$?)))"

E.g.

$ echo $REMOTE_ADDR

$ test -z "$REMOTE_ADDR"; echo $?
0
$ REMOTE_ADDR=127.0.0.1
$ test -z "$REMOTE_ADDR"; echo $?
1
$ retval="$(test -z "$REMOTE_ADDR"; echo $?)"; echo $retval
1
$ unset REMOTE_ADDR
$ retval="$(test -z "$REMOTE_ADDR"; echo $?)"; echo $retval
0

For a program which prints data but also has a return value to be saved, the return value would be captured separately from the output:

# Two different files, 1 and 2.
$ cat 1
1
$ cat 2
2
$ diffs="$(cmp 1 2)"
$ haveDiffs=$?
$ echo "Have differences? [$haveDiffs] Diffs: [$diffs]"
Have differences? [1] Diffs: [1 2 differ: char 1, line 1]
$ diffs="$(cmp 1 1)"

If you a framework like Bootstrap you can make any iframe video responsive by using this snippet:

<div class="embed-responsive embed-responsive-16by9">
    <iframe class="embed-responsive-item" src="vid.mp4" allowfullscreen></iframe>
</div>

You can escape (this is how this principle is called) the double quotes by prefixing them with another double quote. You can put them in a string as follows:

Dim MyVar as string = "some text ""hello"" "

This will give the MyVar variable a value of some text "hello".

My suggestions :

• Keep the program modular. Keep the Calculate class in a separate Calculate.java file and create a new class that calls the main method. This would make the code readable.

• For setting the values in the number, use constructors. Do not use like the methods you have used above like :

  public void setNumber(double fnum, double snum){ this.fn = fnum; this.sn = snum; }

  Constructors exists to initialize the objects.This is their job and they are pretty good at it.

• Getters for members of Calculate class seem in place. But setters are not. Getters and setters serves as one important block in the bridge of efficient programming with java. Put setters for fnum and snum as well

• In the main class, create a Calculate object using the new operator and the constructor in place.

• Call the getAnswer() method with the created Calculate object.

Rest of the code looks fine to me. Be modular. You could read your program in a much better way.

Here is my modular piece of code. Two files : Main.java & Calculate.java

Calculate.java

public class Calculate {


private double fn;
private double sn;
private char op;

    public double getFn() {
        return fn;
    }

    public void setFn(double fn) {
        this.fn = fn;
    }

    public double getSn() {
        return sn;
    }

    public void setSn(double sn) {
        this.sn = sn;
    }

    public char getOp() {
        return op;
    }

    public void setOp(char op) {
        this.op = op;
    }



    public Calculate(double fn, double sn, char op) {
        this.fn = fn;
        this.sn = sn;
        this.op = op;
    }


public void getAnswer(){
    double ans;
    switch (getOp()){
        case '+': 
            ans = add(getFn(), getSn());
            ansOutput(ans);
            break;
        case '-': 
            ans = sub (getFn(), getSn());
            ansOutput(ans);
            break;
        case '*': 
            ans = mul (getFn(), getSn());
            ansOutput(ans);
            break;
        case '/': 
            ans = div (getFn(), getSn());
            ansOutput(ans);
            break;
        default:
            System.out.println("--------------------------");
            System.out.println("Invalid choice of operator");
            System.out.println("--------------------------");
        }
    }
    public static double add(double x,double y){
        return x + y;
    }
    public static double sub(double x, double y){
        return x - y;
    }
    public static double mul(double x, double y){
        return x * y;
    }
    public static double div(double x, double y){
        return x / y;
    }

    public static void ansOutput(double x){
        System.out.println("----------- -------");
        System.out.printf("the answer is %.2f\n", x);
        System.out.println("-------------------");
    }
}

Main.java

public class Main {
    public static void main(String args[])
    {
        Calculate obj = new Calculate(1,2,'+');
        obj.getAnswer();
    }
}

Typescript is (a superset of) javascript, so you just use JSON.parse as you would in javascript:

let obj = JSON.parse(jsonString);

Only that in typescript you can have a type to the resulting object:

interface MyObj {
    myString: string;
    myNumber: number;
}

let obj: MyObj = JSON.parse('{ "myString": "string", "myNumber": 4 }');
console.log(obj.myString);
console.log(obj.myNumber);

(code in playground)

'OR 1=1 is an attempt to make a query succeed no matter what
The /* is an attempt to start a multiline comment so the rest of the query is ignored.

An example would be

SELECT userid 
FROM users 
WHERE username = ''OR 1=1/*' 
    AND password = ''
    AND domain = ''

As you can see if you were to populate the username field without escaping the ' no matter what credentials the user passes in the query would return all userids in the system likely granting access to the attacker (possibly admin access if admin is your first user). You will also notice the remainder of the query would be commented out because of the /* including the real '.

The fact that you can see the value in your database means that it was escaped and that particular attack did not succeed. However, you should investigate if any other attempts were made.

File file = new File("C:/aaa/bbb/ccc/ddd/test.java");
File curentPath = new File(file.getParent());
//get current path "C:/aaa/bbb/ccc/ddd/"
String currentFolder= currentPath.getName().toString();
//get name of file to string "ddd"

if you need to append folder "ddd" by another path use;

String currentFolder= "/" + currentPath.getName().toString();

Try this:

jupyter notebook --NotebookApp.iopub_data_rate_limit=1.0e10

Or this:

yourTerminal:prompt> jupyter notebook --NotebookApp.iopub_data_rate_limit=1.0e10 

which nginx

will give you the path of the nginx being used

EDIT (2017-Jan-18)

Thanks to Will Palmer's comment on this answer, I have added the following...

If you've installed nginx via a package manager such as HomeBrew...

which nginx

may not give you the EXACT path to the nginx being used. You can however find it using

realpath $(which nginx)

and as mentioned by @Daniel Li

you can get configuration of nginx via his method

alternatively you can use this:

nginx -V

int minAccountLevel = int.MaxValue;
int maxAccountLevel = int.MinValue;
foreach (DataRow dr in table.Rows)
{
    int accountLevel = dr.Field<int>("AccountLevel");
    minAccountLevel = Math.Min(minAccountLevel, accountLevel);
    maxAccountLevel = Math.Max(maxAccountLevel, accountLevel);
}

Yes, this really is the fastest way. Using the Linq Min and Max extensions will always be slower because you have to iterate twice. You could potentially use Linq Aggregate, but the syntax isn't going to be much prettier than this already is.

l = [4,76,2,8,6,4,3,7,2,1]
l = l[:5]

You need to use a textarea to get multiline handling.

<textarea name="Text1" cols="40" rows="5"></textarea>

Seems like you could also do this:

__dirname=fs.realpathSync('.');

of course, dont forget fs=require('fs')

(it's not really global in node scripts exactly, its just defined on the module level)

You should try this syntax - assuming you want to have @OrderID as a parameter for your stored procedure:

CREATE PROCEDURE dbo.YourStoredProcNameHere
   @OrderID INT
AS
BEGIN
 DECLARE @OrderItemID AS INT
 DECLARE @AppointmentID AS INT
 DECLARE @PurchaseOrderID AS INT
 DECLARE @PurchaseOrderItemID AS INT
 DECLARE @SalesOrderID AS INT
 DECLARE @SalesOrderItemID AS INT

 SELECT @OrderItemID = OrderItemID 
 FROM [OrderItem] 
 WHERE OrderID = @OrderID

 SELECT @AppointmentID = AppoinmentID 
 FROM [Appointment] 
 WHERE OrderID = @OrderID

 SELECT @PurchaseOrderID = PurchaseOrderID 
 FROM [PurchaseOrder] 
 WHERE OrderID = @OrderID

END

OF course, that only works if you're returning exactly one value (not multiple values!)

using is used for importing namespaces not classes.

So if your class is in namespace X

namespace X
{
    public class MyClass {
         void stuff() {

         }
    }
}

then to use it in another namespace where you want it

using System;
using X;

public class MyMainClass {
    static void Main() {
        MyClass test = new MyClass();
    }
}

To create round corner image using com.google.android.material:material:1.2.0-beta01

 float radius = context.getResources().getDimension(R.dimen.border_radius_hug);
    shapeAppearanceModel = new ShapeAppearanceModel()
            .toBuilder()
            .setAllCorners(CornerFamily.ROUNDED,radius)
            .build();

imageView.setShapeAppearanceModel(shapeAppearanceModel)

or if you want to use it in xml file:

  <com.google.android.material.imageview.ShapeableImageView
            android:id="@+id/thumb"
            android:layout_width="80dp"
            android:layout_height="60dp"
            app:shapeAppearanceOverlay="@style/circleImageView"
            />

in style.xml add this:

<style name="circleImageView" parent="">
      <item name="cornerFamily">rounded</item>
      <item name="cornerSize">10%</item>
</style>

I tested this in Firefox with Firebug using code like this:

console.time("testEquality");
var n = 0;
while (true) {
  n++;
  if (n == 100000)
    break;
}
console.timeEnd("testEquality");

and

console.time("testTypeEquality");
var n = 0;
while (true) {
  n++;
  if (n === 100000)
    break;
}
console.timeEnd("testTypeEquality");

My results (tested five times each and averaged):

==: 115.2
===: 114.4

So I'd say that the miniscule difference (this is over 100000 iterations, remember) is negligible. Performance isn't a reason to do ===. Type safety (well, as safe as you're going to get in JavaScript), and code quality is.

1. Press Windows+R, and type regedit.

2. Go to

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP
   

   Change the value of Start to 4, which means disabled.

3. Reboot your computer.

while working on a security app which needed to get the phone number of who so ever my phone might get into their hands, I had to do this; 1. receive Boot completed and then try getting Line1_Number from telephonyManager which returns a string result. 2. compare the String result with my own phone number and if they don't match or string returns null then, 3. secretly send an SMS containing the string result plus a special sign to my office number. 4. if message sending fails, start a service and keep trying after each hour until sent SMS pending intent returns successful. With this steps I could get the number of the person using my lost phone. it doesn't matter if the person is charged.

Google helps a lot.

My promisify version of a callback function is the P function:

var P = function() {_x000D_
  var self = this;_x000D_
  var method = arguments[0];_x000D_
  var params = Array.prototype.slice.call(arguments, 1);_x000D_
  return new Promise((resolve, reject) => {_x000D_
    if (method && typeof(method) == 'function') {_x000D_
      params.push(function(err, state) {_x000D_
        if (!err) return resolve(state)_x000D_
        else return reject(err);_x000D_
      });_x000D_
      method.apply(self, params);_x000D_
    } else return reject(new Error('not a function'));_x000D_
  });_x000D_
}_x000D_
var callback = function(par, callback) {_x000D_
  var rnd = Math.floor(Math.random() * 2) + 1;_x000D_
  return rnd > 1 ? callback(null, par) : callback(new Error("trap"));_x000D_
}_x000D_
_x000D_
callback("callback", (err, state) => err ? console.error(err) : console.log(state))_x000D_
callback("callback", (err, state) => err ? console.error(err) : console.log(state))_x000D_
callback("callback", (err, state) => err ? console.error(err) : console.log(state))_x000D_
callback("callback", (err, state) => err ? console.error(err) : console.log(state))_x000D_
_x000D_
P(callback, "promise").then(v => console.log(v)).catch(e => console.error(e))_x000D_
P(callback, "promise").then(v => console.log(v)).catch(e => console.error(e))_x000D_
P(callback, "promise").then(v => console.log(v)).catch(e => console.error(e))_x000D_
P(callback, "promise").then(v => console.log(v)).catch(e => console.error(e))

The P function requires that the callback signature must be callback(error,result).

You may also use the stringr package

library(dplyr)
library(stringr)
My.Data %>% filter(str_detect(x, '^G45'))

You may not use '^' (starts with) in this case, to obtain the results you need

$ cat x.mak
all:
    echo $(OPTION)
$ make -f x.mak 'OPTION=-DPASSTOC=42'
echo -DPASSTOC=42
-DPASSTOC=42

Add Permission to Android Manifest

Add this WRITE_EXTERNAL_STORAGE permission to your applications manifest.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="your.company.package"
    android:versionCode="1"
    android:versionName="0.1">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <!-- ... -->
    </application>
    <uses-sdk android:minSdkVersion="7" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
</manifest> 

Check availability of external storage

You should always check for availability first. A snippet from the official android documentation on external storage.

boolean mExternalStorageAvailable = false;
boolean mExternalStorageWriteable = false;
String state = Environment.getExternalStorageState();

if (Environment.MEDIA_MOUNTED.equals(state)) {
    // We can read and write the media
    mExternalStorageAvailable = mExternalStorageWriteable = true;
} else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) {
    // We can only read the media
    mExternalStorageAvailable = true;
    mExternalStorageWriteable = false;
} else {
    // Something else is wrong. It may be one of many other states, but all we need
    //  to know is we can neither read nor write
    mExternalStorageAvailable = mExternalStorageWriteable = false;
}

Use a Filewriter

At last but not least forget about the FileOutputStream and use a FileWriter instead. More information on that class form the FileWriter javadoc. You'll might want to add some more error handling here to inform the user.

// get external storage file reference
FileWriter writer = new FileWriter(getExternalStorageDirectory()); 
// Writes the content to the file
writer.write("This\n is\n an\n example\n"); 
writer.flush();
writer.close();

Short Answer

Yes.

Explanation

It is a good practice since an element can be a part of different groups, and you may want specific elements to be a part of more than one group. The element can hold an infinite number of classes in HTML5, while in HTML4 you are limited by a specific length.

The following example will show you the use of multiple classes.

The first class makes the text color red.

The second class makes the background-color blue.

See how the DOM Element with multiple classes will behave, it will wear both CSS statements at the same time.

Result: multiple CSS statements in different classes will stack up.

You can read more about CSS Specificity.

CSS

.class1 {
    color:red;
}

.class2 {
    background-color:blue;
}

HTML

<div class="class1">text 1</div>
<div class="class2">text 2</div>
<div class="class1 class2">text 3</div>

Live demo

You can't transition between two background images, as there's no way for the browser to know what you want to interpolate. As you've discovered, you can transition the background position. If you want the image to fade in on mouse over, I think the best way to do it with CSS transitions is to put the image on a containing element and then animate the background colour to transparent on the link itself:

span {
    background: url(button.png) no-repeat 0 0;
}
a {
    width: 32px;
    height: 32px;
    text-align: left;
    background: rgb(255,255,255);

    -webkit-transition: background 300ms ease-in 200ms; /* property duration timing-function delay */
    -moz-transition: background 300ms ease-in 200ms;
    -o-transition: background 300ms ease-in 200ms;
    transition: background 300ms ease-in 200ms;
    }
a:hover {
    background: rgba(255,255,255,0);
}

Simple solution for HTML5 ready browsers...

function download(filename, text) {
    var pom = document.createElement('a');
    pom.setAttribute('href', 'data:text/plain;charset=utf-8,' + encodeURIComponent(text));
    pom.setAttribute('download', filename);

    if (document.createEvent) {
        var event = document.createEvent('MouseEvents');
        event.initEvent('click', true, true);
        pom.dispatchEvent(event);
    }
    else {
        pom.click();
    }
}

Usage

download('test.txt', 'Hello world!');

WHY

As mentioned by @Sheepy, the reason why it doesn't work is that java.util.logging.Logger has a root logger that defaults to Level.INFO, and the ConsoleHandler attached to that root logger also defaults to Level.INFO. Therefore, in order to see the FINE (, FINER or FINEST) output, you need to set the default value of the root logger and its ConsoleHandler to Level.FINE as follows:

Logger.getLogger("").setLevel(Level.FINE);
Logger.getLogger("").getHandlers()[0].setLevel(Level.FINE);

The problem of your Update (solution)

As mentioned by @mins, you will have the messages printed twice on the console for INFO and above: first by the anonymous logger, then by its parent, the root logger which also has a ConsoleHandler set to INFO by default. To disable the root logger, you need to add this line of code: logger.setUseParentHandlers(false);

There are other ways to prevent logs from being processed by default Console handler of the root logger mentioned by @Sheepy, e.g.:

Logger.getLogger("").getHandlers()[0].setLevel( Level.OFF );

But Logger.getLogger("").setLevel( Level.OFF ); won't work because it only blocks the message passed directly to the root logger, not the message comes from a child logger. To illustrate how the Logger Hierarchy works, I draw the following diagram:

public void setLevel(Level newLevel) set the log level specifying which message levels will be logged by this logger. Message levels lower than this value will be discarded. The level value Level.OFF can be used to turn off logging. If the new level is null, it means that this node should inherit its level from its nearest ancestor with a specific (non-null) level value.

Just use like this

 $("#sample_id").css("width", "");
 $("#sample_id").css("height", "");

with maven it is automatic:

            override fun onPageFinished(view: WebView?, url: String?) {
                // do your logic
            }
        }

there are a lot of methods that you can override though

Though it's an old post, the question keep coming up and the answers don't always seem clear to me, so, here's my thoughts:

%w and %W are examples of General Delimited Input types, that relate to Arrays. There are other types that include %q, %Q, %r, %x and %i.

The difference between the upper and lower case version is that it gives us access to the features of single and double quotes. With single quotes and (lowercase) %w, we have no code interpolation (#{someCode}) and a limited range of escape characters that work (\\, \n). With double quotes and (uppercase) %W we do have access to these features.

The delimiter used can be any character, not just the open parenthesis. Play with the examples above to see that in effect.

For a full write up with examples of %w and the full list, escape characters and delimiters, have a look at "Ruby - %w vs %W – secrets revealed!"

I found an easy way to do this -

Just enter a command like this -

>mvn -Dtest=TestClassName#methodname -Dmaven.surefire.debug test

It will start listening to 5005 port. Now just create a remote debugging in Eclipse through Debug Configurations for localhost(any host) and port 5005.

For me, often times this is the only reason some code requires Java 6 to compile. Not sure if it's worth it.

Instantiating the Fragment the correct way!

getArguments() setArguments() methods seem very useful when it comes to instantiating a Fragment using a static method.
ie Myfragment.createInstance(String msg)

How to do it?

public MyFragment extends Fragment {

    private String displayMsg;
    private TextView text;

    public static MyFragment createInstance(String displayMsg)
    {
        MyFragment fragment = new MyFragment();
        Bundle args = new Bundle();
        args.setString("KEY",displayMsg);
        fragment.setArguments(args);           //set
        return fragment;
    }

    @Override
    public void onCreate(Bundle bundle)
    {
        displayMsg = getArguments().getString("KEY"):    // get 
    }

    @Override
    public View onCreateView(LayoutInlater inflater, ViewGroup parent, Bundle bundle){
        View view = inflater.inflate(R.id.placeholder,parent,false);
        text = (TextView)view.findViewById(R.id.myTextView);
        text.setText(displayMsg)    // show msg
        returm view;
   }

}

Let's say you want to pass a String while creating an Instance. This is how you will do it.

MyFragment.createInstance("This String will be shown in textView");

You can try this:

JSONObject result = new JSONObject("Your string here").getJSONObject("result");
JSONObject map = result.getJSONObject("map");
JSONArray entries= map.getJSONArray("entry");

I hope this helps.

Eager Loading: Eager Loading helps you to load all your needed entities at once. i.e. related objects (child objects) are loaded automatically with its parent object.

When to use:

1. Use Eager Loading when the relations are not too much. Thus, Eager Loading is a good practice to reduce further queries on the Server.
2. Use Eager Loading when you are sure that you will be using related entities with the main entity everywhere.

Lazy Loading: In case of lazy loading, related objects (child objects) are not loaded automatically with its parent object until they are requested. By default LINQ supports lazy loading.

When to use:

1. Use Lazy Loading when you are using one-to-many collections.
2. Use Lazy Loading when you are sure that you are not using related entities instantly.

NOTE: Entity Framework supports three ways to load related data - eager loading, lazy loading and explicit loading.

I feel I need to clarify one very important thing, for others (like my co-worker) who came across this thread and got the wrong information.

The answer given ("Try decimal(9,2) or decimal(10,2) or whatever.") is correct, but the reason ("increase the number of digits before the decimal") is wrong.

decimal(p,s) and numeric(p,s) both specify a Precision and a Scale. The "precision" is not the number of digits to the left of the decimal, but instead is the total precision of the number.

For example: decimal(2,1) covers 0.0 to 9.9, because the precision is 2 digits (00 to 99) and the scale is 1. decimal(4,1) covers 000.0 to 999.9 decimal(4,2) covers 00.00 to 99.99 decimal(4,3) covers 0.000 to 9.999

You can use

if("/quit".equals(s))
   ...

or

if("/quit".compareTo(s) == 0) 
    ...

The latter makes a lexicographic comparison, and will return 0 if the two strings are the same.

Well guys, the solution to the problem is the following:

1. click in: Start
2. write the word: ejecut
3. After, write: regedit
4. Open the directory: HKEY_LOCAL_MACHINE
5. SOFTWARE
6. Microsoft
7. Windows NT
8. CurrentVersion
9. Perflib
10. Check the following things:

1) Folder 00A: 2) Counter: the last number 3) Help: the last number

   Folder Perflib:
   Last Counter: 00A folder´s Counter 
   Last Help: 00A folder´s Help

Ready, verify the same number in both. success

Simple regex for any number of digits at the end of a string:

'xxx_456'.match(/\d+$/)[0]; //456
'xxx_4567890'.match(/\d+$/)[0]; //4567890

or use split/pop indeed:

('yyy_xxx_45678901').split(/_/).pop(); //45678901

Very simple

let file = $("#fileupload")[0].files[0]; 
file.name

Short answer to this question is -

Hadoop - Is Framework which facilitates distributed file system and programming model which allow us to store humongous sized data and process data in distributed fashion very efficiently and with very less processing time compare to traditional approaches.

(HDFS - Hadoop Distributed File system) (Map Reduce - Programming Model for distributed processing)

Hive - Is query language which allows to read/write data from Hadoop distributed file system in a very popular SQL like fashion. This made life easier for many non-programming background people as they don't have to write Map-Reduce program anymore except for very complex scenarios where Hive is not supported.

Hbase - Is Columnar NoSQL Database. Underlying storage layer for Hbase is again HDFS. Most important use case for this database is to be able to store billion's of rows with million's of columns. Low latency feature of Hbase helps faster and random access of record over distributed data, is very important feature to make it useful for complex projects like Recommender Engines. Also it's record level versioning capability allow user to store transactional data very efficiently (this solves the problem of updating records we have with HDFS and Hive)

Hope this is helpful to quickly understand the above 3 features.

Is there a global object that all vars are hung off of by default? eg: 'globals.noVar declaration'

In /data/app but for copy protection I don't think you can access it.

Try disabling Just My Code (JMC).

• Tools -> Options -> Debugger
• Uncheck "Enable Just my Code"

By default the debugger tries to restrict the view of the world to code that is only contained within your solution. This is really heplful at times but when you want to debug code which is not in your solution (as is your situation) you need to disable JMC in order to see it. Otherwise the code will be treated as external and largely hidden from your view.

EDIT

When you're broken in your code try the following.

• Debug -> Windows -> Modules
• Find the DLL for the project you are interested in
• Right Click -> Load Symbols -> Select the Path to the .PDB for your other project

While its true that git commits don't have a specific field called "username", a git repo does have users, and the users do have names. ;) If what you want is the github username, then knittl's answer is right. But since your question asked about git cli and not github, here's how you get a git user's email address using the command line:

To see a list of all users in a git repo using the git cli:

git log --format="%an %ae" | sort | uniq

To search for a specific user by name, e.g., "John":

git log --format="%an %ae" | sort | uniq | grep -i john

Aside from pandas, Apache pyarrow also provides way to transform parquet to dataframe

The code is simple, just type:

import pyarrow.parquet as pq

df = pq.read_table(source=your_file_path).to_pandas()

For more information, see the document from Apache pyarrow Reading and Writing Single Files

I tried casting to a string and testing for a zero-length string and it worked.

CASE 
   WHEN LEN(CAST(field_value AS VARCHAR(MAX))) = 0 THEN 
       DO THIS
END AS field 

You could try making the imageView size match the image. The following code is not tested.

CGSize kMaxImageViewSize = {.width = 100, .height = 100};
CGSize imageSize = image.size;
CGFloat aspectRatio = imageSize.width / imageSize.height;
CGRect frame = imageView.frame;
if (kMaxImageViewSize.width / aspectRatio <= kMaxImageViewSize.height) 
{
    frame.size.width = kMaxImageViewSize.width;
    frame.size.height = frame.size.width / aspectRatio;
} 
else 
{
    frame.size.height = kMaxImageViewSize.height;
    frame.size.width = frame.size.height * aspectRatio;
}
imageView.frame = frame;

I had a similar question: In the manual, it describes rename as

rename [option] expression replacement file

so you can use it in this way

rename _h _half *.png

In the code: '_h' is the expression that you are looking for. '_half' is the pattern that you want to replace with. '*.png' is the range of files that you are looking for your possible target files.

Hope this can help c:

If you're using SSMS (or old school Enterprise Manager) to edit the table directly, press CTRL+0 to add a null.

You could use OPENROWSET, something like:

SELECT * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
  'Excel 8.0;IMEX=1;HDR=NO;DATABASE=C:\FILE.xls', 'Select * from [Sheet1$]'

Just make sure the path is a path on the server, not your local machine.

I personally think that sizeof(a) / sizeof(*a) looks cleaner.

I also prefer to define it as a macro:

#define NUM(a) (sizeof(a) / sizeof(*a))

Then you can use it in for-loops, thusly:

for (i = 0; i < NUM(a); i++)

This worked for me, it works in firefox, ie and chrome.

    var content = "This is a test Message";

    var contentHtml = [
        '<div><b>',
        'TestReport',
        '<button style="float:right; margin-right:10px;"',
        'id="printButton" onclick="printDocument()">Print</button></div>',
        content
    ].join('');

    var printWindow = window.open();

    printWindow.document.write('<!DOCTYPE HTML><html><head<title>Reports</title>',
        '<script>function printDocument() {',
        'window.focus();',
        'window.print();',
        'window.close();',
        '}',
        '</script>');

    printWindow.document.write("stylesheet link here");

    printWindow.document.write('</head><body>');
    printWindow.document.write(contentHtml);
    printWindow.document.write('</body>');
    printWindow.document.write('</html>');
    printWindow.document.close();

Definitions:

• Frame Layout: This is designed to block out an area on the screen to display a single item.
• Linear Layout: A layout that arranges its children in a single column or a single row.
• Relative Layout: This layout is a view group that displays child views in relative positions.
• Table Layout: A layout that arranges its children into rows and columns.

More Information:

FrameLayout

FrameLayout is designed to block out an area on the screen to display a single item. Generally, FrameLayout should be used to hold a single child view, because it can be difficult to organize child views in a way that's scalable to different screen sizes without the children overlapping each other. You can, however, add multiple children to a FrameLayout and control their position within the FrameLayout by assigning gravity to each child, using the android:layout_gravity attribute.

Child views are drawn in a stack, with the most recently added child on top. The size of the FrameLayout is the size of its largest child (plus padding), visible or not (if the FrameLayout's parent permits).

RelativeLayout

A RelativeLayout is a very powerful utility for designing a user interface because it can eliminate nested view groups and keep your layout hierarchy flat, which improves performance. If you find yourself using several nested LinearLayout groups, you may be able to replace them with a single RelativeLayout.

(Current docs here)

TableLayout

A TableLayout consists of a number of TableRow objects, each defining a row (actually, you can have other children, which will be explained below). TableLayout containers do not display border lines for their rows, columns, or cells. Each row has zero or more cells; each cell can hold one View object. The table has as many columns as the row with the most cells. A table can leave cells empty. Cells can span columns, as they can in HTML.

The width of a column is defined by the row with the widest cell in that column.

Note: Absolute Layout is deprecated.

using sklearn library preprocessing class

from sklearn.impute import SimpleImputer
missingvalues = SimpleImputer(missing_values = np.nan, strategy = 'mean', axis = 0)
missingvalues = missingvalues.fit(x[:,1:3])
x[:,1:3] = missingvalues.transform(x[:,1:3])

Note: In the recent version parameter missing_values value change to np.nan from NaN

Since the other answers explained how to do it without actually explaining why it works:

When the switch executes, it finds the first matching case statement and then executes each line of code after the switch until it hits either a break statement or the end of the switch (or a return statement to leave the entire containing function). When you deliberately omit the break so that code under the next case gets executed too that's called a fall-through. So for the OP's requirement:

switch (pageid) {
   case "listing-page":
   case "home-page":
      alert("hello");
      break;

   case "details-page":
      alert("goodbye");
      break;
} 

Forgetting to include break statements is a fairly common coding mistake and is the first thing you should look for if your switch isn't working the way you expected. For that reason some people like to put a comment in to say "fall through" to make it clear when break statements have been omitted on purpose. I do that in the following example since it is a bit more complicated and shows how some cases can include code to execute before they fall-through:

switch (someVar) {
   case 1:
      someFunction();
      alert("It was 1");
      // fall through
   case 2:
      alert("The 2 case");
      // fall through
   case 3:
      // fall through
   case 4:
      // fall through
   case 5:
      alert("The 5 case");
      // fall through
   case 6:
      alert("The 6 case");
      break;

   case 7:
      alert("Something else");
      break;

   case 8:
      // fall through
   default:
      alert("The end");
      break;
}

You can also (optionally) include a default case, which will be executed if none of the other cases match - if you don't include a default and no cases match then nothing happens. You can (optionally) fall through to the default case.

So in my second example if someVar is 1 it would call someFunction() and then you would see four alerts as it falls through multiple cases some of which have alerts under them. Is someVar is 3, 4 or 5 you'd see two alerts. If someVar is 7 you'd see "Something else" and if it is 8 or any other value you'd see "The end".

They arent missing, the path is wrong. Its looking in non-existent dir 'img' for a file that is in dir 'images'.

To fix either edit the file that declares the wrong path or as I did just make a softlink like

ln -s images img

Different ways:

1. Using SQL Server Agent (If local instance)
   schedule a job in sql server agent with a new step having type as "T-SQL" then run the job.

2. Using SQLCMD

Have a look at PowerCollections over at CodePlex. Apart from Set and OrderedSet it has a few other usefull collection types such as Deque, MultiDictionary, Bag, OrderedBag, OrderedDictionary and OrderedMultiDictionary.

For more collections, there is also the C5 Generic Collection Library.

Another way:

var := coalesce (var, 5);

COALESCE is the ANSI equivalent (more or less) of Oracle's NVL function.

Couldn't you just pass the a name attribute and wrap it in a form?

<form id="form" action="do_stuff.php" method="post">
    <select id="select_catalog" name="select_catalog_query">
    <?php <<<INSERT THE SELECT OPTION LOOP>>> ?>
    </select>
</form>

And then look for $_POST['select_catalog_query'] ?

An abstract class is a class that contains at least one abstract method, which is a method without any actual code in it, just the name and the parameters, and that has been marked as "abstract".

The purpose of this is to provide a kind of template to inherit from and to force the inheriting class to implement the abstract methods.

An abstract class thus is something between a regular class and a pure interface. Also interfaces are a special case of abstract classes where ALL methods are abstract.

See this section of the PHP manual for further reference.

Just try this.

<asp:TextBox ID="tb" onkeypress="javascript:return false;" width="50px" runat="server"></asp:TextBox>

This won't allow any characters to be entered inside the TextBox.

Let's go in reverse order:

• Log.e: This is for when bad stuff happens. Use this tag in places like inside a catch statement. You know that an error has occurred and therefore you're logging an error.

• Log.w: Use this when you suspect something shady is going on. You may not be completely in full on error mode, but maybe you recovered from some unexpected behavior. Basically, use this to log stuff you didn't expect to happen but isn't necessarily an error. Kind of like a "hey, this happened, and it's weird, we should look into it."

• Log.i: Use this to post useful information to the log. For example: that you have successfully connected to a server. Basically use it to report successes.

• Log.d: Use this for debugging purposes. If you want to print out a bunch of messages so you can log the exact flow of your program, use this. If you want to keep a log of variable values, use this.

• Log.v: Use this when you want to go absolutely nuts with your logging. If for some reason you've decided to log every little thing in a particular part of your app, use the Log.v tag.

And as a bonus...

• Log.wtf: Use this when stuff goes absolutely, horribly, holy-crap wrong. You know those catch blocks where you're catching errors that you never should get...yeah, if you wanna log them use Log.wtf

I am not experienced with Eclipse or Maven so the other answers seemed a bit over complicated.

The following simpler set of steps worked for me:

Prerequisite: Make sure you have Maven plugin installed in your Eclipse IDE: How to add Maven plugin to Eclipse

1. Open Eclipse
2. Click File > Import
3. Type Maven in the search box under Select an import source:
4. Select Existing Maven Projects
5. Click Next
6. Click Browse and select the folder that is the root of the Maven project (probably contains the pom.xml file)
7. Click Next
8. Click Finish

Recommendedations from the Python 2.7 docs for the time module

For Python 3, scipy has the function scipy.special.comb, which may produce floating point as well as exact integer results

import scipy.special

res = scipy.special.comb(x, y, exact=True)

See the documentation for scipy.special.comb.

For Python 2, the function is located in scipy.misc, and it works the same way:

import scipy.misc

res = scipy.misc.comb(x, y, exact=True)

Inspired by @ford04 answer I use this hook, which also takes callbacks for success, errors, finally and an abortFn:

export const useAsync = (
        asyncFn, 
        onSuccess = false, 
        onError = false, 
        onFinally = false, 
        abortFn = false
    ) => {

    useEffect(() => {
        let isMounted = true;
        const run = async () => {
            try{
                let data = await asyncFn()
                if (isMounted && onSuccess) onSuccess(data)
            } catch(error) {
                if (isMounted && onError) onSuccess(error)
            } finally {
                if (isMounted && onFinally) onFinally()
            }
        }
        run()
        return () => {
            if(abortFn) abortFn()
            isMounted = false
        };
    }, [asyncFn, onSuccess])
}

If the asyncFn is doing some kind of fetch from back-end it often makes sense to abort it when the component is unmounted (not always though, sometimes if ie. you're loading some data into a store you might as well just want to finish it even if component is unmounted)

I am using an IsNullConverter class in my project and it worked for me. here is the code for it in c#,create a folder named Converter and add this class in that folder,as the trigger used doesnt supports value for rather than null,and IsNullConverter just do that

 public class IsNullConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        return (value == null);
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new InvalidOperationException("IsNullConverter can only be used OneWay.");
    }
}

add the namespace in xaml file like this.

xmlns:Converters="clr-namespace:TymeSheet.Converter"

means

xmlns:Converters="clr-namespace:YourProjectName.Converter"

use this line below the resources to make it availabe through xaml code

<Converters:IsNullConverter x:Key="isNullConverter" />

here is the xaml code,i used here the trigger so whenever an item is selected in the combobox the visibilty of your text becomes false.

                            <Converters:IsNullConverter x:Key="isNullConverter"/>
                        </TextBlock.Resources>
                        <TextBlock.Style>
                            <Style TargetType="TextBlock">

                                        <Setter Property="Visibility" Value="Hidden"/>
                                    </DataTrigger>
                                </Style.Triggers>
                            </Style>
                        </TextBlock.Style>
                    </TextBlock>

To disagree with the official answer:

:set list will not show ^M characters (CRs). Supplying the -b option to vi/vim will work. Or, once vim is loaded, type :e ++ff=unix.

try this:

    ActionBar actionBar = getSupportActionBar();
    actionBar.setDisplayShowHomeEnabled(false);
    actionBar.setDisplayShowCustomEnabled(true);
    actionBar.setDisplayShowTitleEnabled(false);
    View customView = getLayoutInflater().inflate(R.layout.main_action_bar, null);
    actionBar.setCustomView(customView);
    Toolbar parent =(Toolbar) customView.getParent();
    parent.setPadding(0,0,0,0);//for tab otherwise give space in tab
    parent.setContentInsetsAbsolute(0,0);

I used this code in my project,good luck;

That is how you define an anonymous function that gets called when the document is ready.

Some people have asked: how can the singleton return a null pointer? I'm answering that question. (I cannot answer in a comment because I need to post code.)

It may return null in between two events: (1) the class is loaded, and (2) the object of this class is created. Here's an example:

class X {
    static X xinstance;
    static Y yinstance = Y.yinstance;
    X() {xinstance=this;}
}
class Y {
    static X xinstance = X.xinstance;
    static Y yinstance;
    Y() {yinstance=this;}
}

public class A {
    public static void main(String[] p) {
    X x = new X();
    Y y = new Y();
    System.out.println("x:"+X.xinstance+" y:"+Y.yinstance);
    System.out.println("x:"+Y.xinstance+" y:"+X.yinstance);
    }
}

Let's run the code:

$ javac A.java 
$ java A
x:X@a63599 y:Y@9036e
x:null y:null

The second line shows that Y.xinstance and X.yinstance are null; they are null because the variables X.xinstance ans Y.yinstance were read when they were null.

Can this be fixed? Yes,

class X {
    static Y y = Y.getInstance();
    static X theinstance;
    static X getInstance() {if(theinstance==null) {theinstance = new X();} return theinstance;}
}
class Y {
    static X x = X.getInstance();
    static Y theinstance;
    static Y getInstance() {if(theinstance==null) {theinstance = new Y();} return theinstance;}
}

public class A {
    public static void main(String[] p) {
    System.out.println("x:"+X.getInstance()+" y:"+Y.getInstance());
    System.out.println("x:"+Y.x+" y:"+X.y);
    }
}

and this code shows no anomaly:

$ javac A.java 
$ java A
x:X@1c059f6 y:Y@152506e
x:X@1c059f6 y:Y@152506e

BUT this is not an option for the Android Application object: the programmer does not control the time when it is created.

Once again: the difference between the first example and the second one is that the second example creates an instance if the static pointer is null. But a programmer cannot create the Android application object before the system decides to do it.

UPDATE

One more puzzling example where initialized static fields happen to be null.

Main.java:

enum MyEnum {
    FIRST,SECOND;
    private static String prefix="<", suffix=">";
    String myName;
    MyEnum() {
        myName = makeMyName();
    }
    String makeMyName() {
        return prefix + name() + suffix;
    }
    String getMyName() {
        return myName;
    }
}
public class Main {
    public static void main(String args[]) {
        System.out.println("first: "+MyEnum.FIRST+" second: "+MyEnum.SECOND);
        System.out.println("first: "+MyEnum.FIRST.makeMyName()+" second: "+MyEnum.SECOND.makeMyName());
        System.out.println("first: "+MyEnum.FIRST.getMyName()+" second: "+MyEnum.SECOND.getMyName());
    }
}

And you get:

$ javac Main.java
$ java Main
first: FIRST second: SECOND
first: <FIRST> second: <SECOND>
first: nullFIRSTnull second: nullSECONDnull

Note that you cannot move the static variable declaration one line upper, the code will not compile.

Error control operator

In case the warning is expected you can use the error control operator @ to suppress thrown messages.

$role_arr = getRole(@$response->records);

While this reduces clutter in your code you should use it with caution as it may make debugging future errors harder. An example where using @ may be useful is when creating an object from user input and running it through a validation method before using it in further logic.

Null Coalesce Operator

Another alternative is using the isset_ternary operator ??. This allows you to avoid warnings and assign default value in a short one line fashion.

$role_arr = getRole($response->records ?? null);

If none of them are working then check this.. say if you have x and y arrays of data along respective axis. Then check in which cell(jupyter) you have initialized x and y to empty. This is because , maybe you are appending data to x and y without re-initializing them. So plot has old data too. So check that..

A programming language implementation is a system for executing computer programs.

There are two general approaches to programming language implementation:

• Interpretation: An interpreter takes as input a program in some language, and performs the actions written in that language on some machine.
• Compilation: A compiler takes as input a program in some language, and translates that program into some other language, which may serve as input to another interpreter or another compiler.

Python is an interpreted high-level programming language created by Guido van Rossum in 1991.

CPython is reference version of the Python computing language, which is written in C created by Guido van Rossum too.

You can use this one check:

create or replace function to_n(c varchar2) return number is
begin return to_number(c);
exception when others then return -123456;
end;

select id, n from t where to_n(n) = -123456;

In my use case, I parameterized some fields in an HTML document, and once I load these fields I match and replace them using the str_replace method.

<?php echo str_replace(array("{{client_name}}", "{{client_testing}}"), array('client_company_name', 'test'), 'html_document'); ?>

Hehe, curious. I think this is an "intentianal bug", so to speak.

The underlying reason is how the Integer class is written. Basically, parseInt is "optimized" for positive numbers. When it parses the string, it builds the result cumulatively, but negated. Then it flips the sign of the end-result.

Example:

66 = 0x42

parsed like:

4*(-1) = -4
-4 * 16 = -64 (hex 4 parsed)

-64 - 2 = -66 (hex 2 parsed)

return -66 * (-1) = 66

Now, let's look at your example FFFF8000

16*(-1) = -16 (first F parsed)
-16*16 = -256 

-256 - 16 = -272 (second F parsed)
-272 * 16 = -4352 

-4352 - 16 = -4368 (third F parsed)
-4352 * 16 = -69888

-69888 - 16 = -69904 (forth F parsed)
-69904 * 16 = -1118464 

-1118464 - 8 = -1118472 (8 parsed)
-1118464 * 16 = -17895552 

-17895552 - 0 = -17895552 (first 0 parsed)
Here it blows up since -17895552 < -Integer.MAX_VALUE / 16 (-134217728). 
Attempting to execute the next logical step in the chain (-17895552 * 16)
would cause an integer overflow error.

Edit (addition): in order for the parseInt() to work "consistently" for -Integer.MAX_VALUE <= n <= Integer.MAX_VALUE, they would have had to implement logic to "rotate" when reaching -Integer.MAX_VALUE in the cumulative result, starting over at the max-end of the integer range and continuing downwards from there. Why they did not do this, one would have to ask Josh Bloch or whoever implemented it in the first place. It might just be an optimization.

However,

Hex=Integer.toHexString(Integer.MAX_VALUE);
System.out.println(Hex);
System.out.println(Integer.parseInt(Hex.toUpperCase(), 16));

works just fine, for just this reason. In the sourcee for Integer you can find this comment.

// Accumulating negatively avoids surprises near MAX_VALUE

Try this:

div {
    border: 1px solid black;
    width: 70px;
    overflow: hidden;
    white-space: nowrap;
}

SQL Server: How to set auto-increment on a table with rows in it:

This strategy physically copies the rows around twice which can take a much longer time if the table you are copying is very large.

You could save out your data, drop and rebuild the table with the auto-increment and primary key, then load the data back in.

I'll walk you through with an example:

Step 1, create table foobar (without primary key or auto-increment):

CREATE TABLE foobar(
    id int NOT NULL,
    name nchar(100) NOT NULL,
)

Step 2, insert some rows

insert into foobar values(1, 'one');
insert into foobar values(2, 'two');
insert into foobar values(3, 'three');

Step 3, copy out foobar data into a temp table:

select * into temp_foobar from foobar

Step 4, drop table foobar:

drop table foobar;

Step 5, recreate your table with the primary key and auto-increment properties:

CREATE TABLE foobar(
    id int primary key IDENTITY(1, 1) NOT NULL,
    name nchar(100) NOT NULL,
)

Step 6, insert your data from temp table back into foobar

SET IDENTITY_INSERT temp_foobar ON
INSERT into foobar (id, name) select id, name from temp_foobar;

Step 7, drop your temp table, and check to see if it worked:

drop table temp_foobar;
select * from foobar;

You should get this, and when you inspect the foobar table, the id column is auto-increment of 1 and id is a primary key:

1    one
2    two
3    three

This worked for me, I added images.sort() to keep the sequence order:

import cv2
import numpy as np
import os

image_folder = 'data-set-race-01'
video_file = 'race-01.mp4'
image_size = (160, 120)
fps = 24

images = [img for img in os.listdir(image_folder) if img.endswith(".jpg")]
images.sort()

out = cv2.VideoWriter(video_file, cv2.VideoWriter_fourcc(*'MP4V'), fps, image_size)

img_array = []
for filename in images:
    img = cv2.imread(os.path.join(image_folder, filename))
    img_array.append(img)
    out.write(img)

out.release()

Another approach for same issue may help you Read and write file in private context of application

                 String NOTE = "note.txt";  
                 private void writeToFile() {
        try {
         OutputStreamWriter out = new OutputStreamWriter(openFileOutput(
                NOTES, 0));

         out.write("testing");
         out.close();
         }

        catch (Throwable t) {
        Toast.makeText(this, "Exception: " + t.toString(), 2000).show();
        }
             }


           private void ReadFromFile()
      {
        try {
        InputStream in = openFileInput(NOTES);
        if (in != null) {
            InputStreamReader tmp = new InputStreamReader(in);
            BufferedReader reader = new BufferedReader(tmp);
            String str;
            StringBuffer buf = new StringBuffer();
            while ((str = reader.readLine()) != null) {
                buf.append(str + "\n");
            }
            in.close();
            String temp = "Not Working";
            temp = buf.toString();
            Toast.makeText(this, temp, Toast.LENGTH_SHORT).show();
        }
    } catch (java.io.FileNotFoundException e) {
        // that's OK, we probably haven't created it yet
    } catch (Throwable t) {
        Toast.makeText(this, "Exception: " + t.toString(), 2000).show();
    }
}

The 1.3 docs offer a very simple solution: KeyedTuple._asdict()

def to_array(rows):
    return [r._asdict() for r in rows]

def query():
    data = session.query(Table).all()
    return to_array(data)

You could put the body of your script into a function and then you could return from that function.

def main():
  done = True
  if done:
    return
    # quit/stop/exit
  else:
    # do other stuff

if __name__ == "__main__":
  #Run as main program
  main()

JavaBeans

A JavaBean is a class that follows the JavaBeans conventions as defined by Sun. Wikipedia has a pretty good summary of what JavaBeans are:

JavaBeans are reusable software components for Java that can be manipulated visually in a builder tool. Practically, they are classes written in the Java programming language conforming to a particular convention. They are used to encapsulate many objects into a single object (the bean), so that they can be passed around as a single bean object instead of as multiple individual objects. A JavaBean is a Java Object that is serializable, has a nullary constructor, and allows access to properties using getter and setter methods.

In order to function as a JavaBean class, an object class must obey certain conventions about method naming, construction, and behavior. These conventions make it possible to have tools that can use, reuse, replace, and connect JavaBeans.

The required conventions are:

• The class must have a public default constructor. This allows easy instantiation within editing and activation frameworks.
• The class properties must be accessible using get, set, and other methods (so-called accessor methods and mutator methods), following a standard naming convention. This allows easy automated inspection and updating of bean state within frameworks, many of which include custom editors for various types of properties.
• The class should be serializable. This allows applications and frameworks to reliably save, store, and restore the bean's state in a fashion that is independent of the VM and platform.

Because these requirements are largely expressed as conventions rather than by implementing interfaces, some developers view JavaBeans as Plain Old Java Objects that follow specific naming conventions.

POJO

A Plain Old Java Object or POJO is a term initially introduced to designate a simple lightweight Java object, not implementing any javax.ejb interface, as opposed to heavyweight EJB 2.x (especially Entity Beans, Stateless Session Beans are not that bad IMO). Today, the term is used for any simple object with no extra stuff. Again, Wikipedia does a good job at defining POJO:

POJO is an acronym for Plain Old Java Object. The name is used to emphasize that the object in question is an ordinary Java Object, not a special object, and in particular not an Enterprise JavaBean (especially before EJB 3). The term was coined by Martin Fowler, Rebecca Parsons and Josh MacKenzie in September 2000:

"We wondered why people were so against using regular objects in their systems and concluded that it was because simple objects lacked a fancy name. So we gave them one, and it's caught on very nicely."

The term continues the pattern of older terms for technologies that do not use fancy new features, such as POTS (Plain Old Telephone Service) in telephony, and PODS (Plain Old Data Structures) that are defined in C++ but use only C language features, and POD (Plain Old Documentation) in Perl.

The term has most likely gained widespread acceptance because of the need for a common and easily understood term that contrasts with complicated object frameworks. A JavaBean is a POJO that is serializable, has a no-argument constructor, and allows access to properties using getter and setter methods. An Enterprise JavaBean is not a single class but an entire component model (again, EJB 3 reduces the complexity of Enterprise JavaBeans).

As designs using POJOs have become more commonly-used, systems have arisen that give POJOs some of the functionality used in frameworks and more choice about which areas of functionality are actually needed. Hibernate and Spring are examples.

Value Object

A Value Object or VO is an object such as java.lang.Integer that hold values (hence value objects). For a more formal definition, I often refer to Martin Fowler's description of Value Object:

In Patterns of Enterprise Application Architecture I described Value Object as a small object such as a Money or date range object. Their key property is that they follow value semantics rather than reference semantics.

You can usually tell them because their notion of equality isn't based on identity, instead two value objects are equal if all their fields are equal. Although all fields are equal, you don't need to compare all fields if a subset is unique - for example currency codes for currency objects are enough to test equality.

A general heuristic is that value objects should be entirely immutable. If you want to change a value object you should replace the object with a new one and not be allowed to update the values of the value object itself - updatable value objects lead to aliasing problems.

Early J2EE literature used the term value object to describe a different notion, what I call a Data Transfer Object. They have since changed their usage and use the term Transfer Object instead.

You can find some more good material on value objects on the wiki and by Dirk Riehle.

Data Transfer Object

Data Transfer Object or DTO is a (anti) pattern introduced with EJB. Instead of performing many remote calls on EJBs, the idea was to encapsulate data in a value object that could be transfered over the network: a Data Transfer Object. Wikipedia has a decent definition of Data Transfer Object:

Data transfer object (DTO), formerly known as value objects or VO, is a design pattern used to transfer data between software application subsystems. DTOs are often used in conjunction with data access objects to retrieve data from a database.

The difference between data transfer objects and business objects or data access objects is that a DTO does not have any behaviour except for storage and retrieval of its own data (accessors and mutators).

In a traditional EJB architecture, DTOs serve dual purposes: first, they work around the problem that entity beans are not serializable; second, they implicitly define an assembly phase where all data to be used by the view is fetched and marshalled into the DTOs before returning control to the presentation tier.

So, for many people, DTOs and VOs are the same thing (but Fowler uses VOs to mean something else as we saw). Most of time, they follow the JavaBeans conventions and are thus JavaBeans too. And all are POJOs.

Typical code is to create an explicit method to add to the list, and create the ArrayList on the fly when adding. Note the synchronization so the list only gets created once!

@Override
public synchronized boolean addToList(String key, Item item) {
   Collection<Item> list = theMap.get(key);
   if (list == null)  {
      list = new ArrayList<Item>();  // or, if you prefer, some other List, a Set, etc...
      theMap.put(key, list );
   }

   return list.add(item);
}

To Select an Option Via Text;

(new SelectElement(driver.FindElement(By.XPath(""))).SelectByText("");

To Select an Option via Value:

 (new SelectElement(driver.FindElement(By.XPath(""))).SelectByValue("");

You can try using this way :

sentence ["Robert"] = "Roger"

Then the sentence will become :

sentence = "My name is Roger" # Robert is replaced with Roger

The issue here was that myString had that header line. Either there was some hidden character at the beginning of the first line or the line itself was causing the error. I sliced off the first line like so:

xml.LoadXml(myString.Substring(myString.IndexOf(Environment.NewLine)));

This solved my problem.

It's been 10 years since this question was asked. And I hope this answer will be useful to someone. As mentioned in the answer here, where GUI is not an option, Andrew Shadura's crecord extension helps bring a ncurses window in which we can select the lines to commit.

Set up the extension as follows:

git clone https://github.com/andrewshadura/git-crecord
cd git-crecord
./setup.py install
ln -s $PWD/git-crecord ~/.local/bin/git-crecord

cd to your git repo and invoke it as follows:

git crecord

This would bring up the ncurses interface which can be used as shown below. Pressing the following keys in the ncurses window will do certain actions:

f       hunk toggle fold (arrow keys can also be used)
space   toggle hunk selection
a       toggle commit or amend
c       confirm and open commit window

Screencast showing a sample usage

Let's say you have these lines of code:

test line one
test line two
test line three
test line four

Using Search and Replace Ctrl+H with Regex let's find this: ^ and replace it with ", we'll have this:

"test line one
"test line two
"test line three
"test line four

Now let's search this: $ and replace it with ", now we'll have this:

"test line one"
"test line two"
"test line three"
"test line four"

Disable the firewall and try to connect.

If that works, then enable the firewall and

Windows Defender Firewall -> Advanced Settings -> Inbound Rules(Right Click) -> New Rules -> Port -> Allow Port 1433 (Public and Private) -> Add

Do the same for Outbound Rules.

Then Try again.

pip install django-cors-headers

and then add it to your installed apps:

INSTALLED_APPS = (
    ...
    'corsheaders',
    ...
)

You will also need to add a middleware class to listen in on responses:

MIDDLEWARE_CLASSES = (
    ...
    'corsheaders.middleware.CorsMiddleware',  
    'django.middleware.common.CommonMiddleware',  
    ...
)

CORS_ORIGIN_ALLOW_ALL = True # If this is used then `CORS_ORIGIN_WHITELIST` will not have any effect
CORS_ALLOW_CREDENTIALS = True
CORS_ORIGIN_WHITELIST = [
    'http://localhost:3030',
] # If this is used, then not need to use `CORS_ORIGIN_ALLOW_ALL = True`
CORS_ORIGIN_REGEX_WHITELIST = [
    'http://localhost:3030',
]

read the official documentation can resolve almost all problem

You can use .is(':visible')

Selects all elements that are visible.

For example:

if($('#selectDiv').is(':visible')){

Also, you can get the div which is visible by:

$('div:visible').callYourFunction();

Live example:

console.log($('#selectDiv').is(':visible'));_x000D_
console.log($('#visibleDiv').is(':visible'));

#selectDiv {_x000D_
  display: none;  _x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="selectDiv"></div>_x000D_
<div id="visibleDiv"></div>

Thanks for the answers. Now I know that there are two ways of "SAVE AS" in Vim.

Assumed that I'm editing hello.txt.

• :w world.txt will write hello.txt's content to the file world.txt while keeping hello.txt as the opened buffer in vim.
• :sav world.txt will first write hello.txt's content to the file world.txt, then close buffer hello.txt, finally open world.txt as the current buffer.

 var url = "http://www.example.com";
 window.open(url, '_blank');

I made an eol module for working with line endings in node or browsers. It has a split method like

var lines = eol.split(text)

To avoid blinking problem use following code
its not mouseover and mouseout instead of that use mouseenter and mouseleave


**app.component.html**

    <div (mouseenter)="changeText=true" (mouseleave)="changeText=false">
      <span *ngIf="!changeText">Hide</span>
      <span *ngIf="changeText">Show</span>
    </div>

**app.component.ts**

@Component({
   selector: 'app-main',
   templateUrl: './app.component.html'
})
export class AppComponent {
    changeText: boolean;
    constructor() {
       this.changeText = false;
    }
}
