In my case the problem was that GNOME keyring was holding an invalid passphrase for the ssh key to be used. After spending indecent amount of time troubleshooting this issue I ran seahorse and found the entry to hold empty string. I can only guess that it was caused by mistyping the passphrase at first use some time earlier, and then probably cancelling the requester or so in order to fall back to command line. Updating the entry with correct passphrase immediately solved the problem. Deleting that entry (from "login" keyring) and reentering passphrase at that first prompt (and checking the appropriate checkbox) solves this too. Now agent gets the correct passphrase from the unlocked at login keyring named "login" and neither asks for passphrase nor "refuses operation" anymore. Of course YMMV.

While this question is old, the answers aren't proper. Context menus have their own events on DataGridView. There is an event for row context menu and cell context menu.

The reason for which these answers aren't proper is they do not account for different operation schemes. Accessibility options, remote connections, or Metro/Mono/Web/WPF porting might not work and keyboard shortcuts will down right fail (Shift+F10 or Context Menu key).

Cell selection on right mouse click has to be handled manually. Showing the context menu does not need to be handled as this is handled by the UI.

This completely mimics the approach used by Microsoft Excel. If a cell is part of a selected range, the cell selection doesn't change and neither does CurrentCell. If it isn't, the old range is cleared and the cell is selected and becomes CurrentCell.

If you are unclear on this, CurrentCell is where the keyboard has focus when you press the arrow keys. Selected is whether it is part of SelectedCells. The context menu will show on right click as handled by the UI.

private void dgvAccount_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
{
    if (e.ColumnIndex != -1 && e.RowIndex != -1 && e.Button == System.Windows.Forms.MouseButtons.Right)
    {
        DataGridViewCell c = (sender as DataGridView)[e.ColumnIndex, e.RowIndex];
        if (!c.Selected)
        {
            c.DataGridView.ClearSelection();
            c.DataGridView.CurrentCell = c;
            c.Selected = true;
        }
    }
}

Keyboard shortcuts do not show the context menu by default, so we have to add them in.

private void dgvAccount_KeyDown(object sender, KeyEventArgs e)
{
    if ((e.KeyCode == Keys.F10 && e.Shift) || e.KeyCode == Keys.Apps)
    {
        e.SuppressKeyPress = true;
        DataGridViewCell currentCell = (sender as DataGridView).CurrentCell;
        if (currentCell != null)
        {
            ContextMenuStrip cms = currentCell.ContextMenuStrip;
            if (cms != null)
            {
                Rectangle r = currentCell.DataGridView.GetCellDisplayRectangle(currentCell.ColumnIndex, currentCell.RowIndex, false);
                Point p = new Point(r.X + r.Width, r.Y + r.Height);
                cms.Show(currentCell.DataGridView, p);
            }
        }
    }
}

I've reworked this code to work statically, so you can copy and paste them into any event.

The key is to use CellContextMenuStripNeeded since this will give you the context menu.

Here's an example using CellContextMenuStripNeeded where you can specify which context menu to show if you want to have different ones per row.

In this context MultiSelect is True and SelectionMode is FullRowSelect. This is just for the example and not a limitation.

private void dgvAccount_CellContextMenuStripNeeded(object sender, DataGridViewCellContextMenuStripNeededEventArgs e)
{
    DataGridView dgv = (DataGridView)sender;

    if (e.RowIndex == -1 || e.ColumnIndex == -1)
        return;
    bool isPayment = true;
    bool isCharge = true;
    foreach (DataGridViewRow row in dgv.SelectedRows)
    {
        if ((string)row.Cells["P/C"].Value == "C")
            isPayment = false;
        else if ((string)row.Cells["P/C"].Value == "P")
            isCharge = false;
    }
    if (isPayment)
        e.ContextMenuStrip = cmsAccountPayment;
    else if (isCharge)
        e.ContextMenuStrip = cmsAccountCharge;
}

private void cmsAccountPayment_Opening(object sender, CancelEventArgs e)
{
    int itemCount = dgvAccount.SelectedRows.Count;
    string voidPaymentText = "&Void Payment"; // to be localized
    if (itemCount > 1)
        voidPaymentText = "&Void Payments"; // to be localized
    if (tsmiVoidPayment.Text != voidPaymentText) // avoid possible flicker
        tsmiVoidPayment.Text = voidPaymentText;
}

private void cmsAccountCharge_Opening(object sender, CancelEventArgs e)
{
    int itemCount = dgvAccount.SelectedRows.Count;
    string deleteChargeText = "&Delete Charge"; //to be localized
    if (itemCount > 1)
        deleteChargeText = "&Delete Charge"; //to be localized
    if (tsmiDeleteCharge.Text != deleteChargeText) // avoid possible flicker
        tsmiDeleteCharge.Text = deleteChargeText;
}

private void tsmiVoidPayment_Click(object sender, EventArgs e)
{
    int paymentCount = dgvAccount.SelectedRows.Count;
    if (paymentCount == 0)
        return;

    bool voidPayments = false;
    string confirmText = "Are you sure you would like to void this payment?"; // to be localized
    if (paymentCount > 1)
        confirmText = "Are you sure you would like to void these payments?"; // to be localized
    voidPayments = (MessageBox.Show(
                    confirmText,
                    "Confirm", // to be localized
                    MessageBoxButtons.YesNo,
                    MessageBoxIcon.Warning,
                    MessageBoxDefaultButton.Button2
                   ) == DialogResult.Yes);
    if (voidPayments)
    {
        // SQLTransaction Start
        foreach (DataGridViewRow row in dgvAccount.SelectedRows)
        {
            //do Work    
        }
    }
}

private void tsmiDeleteCharge_Click(object sender, EventArgs e)
{
    int chargeCount = dgvAccount.SelectedRows.Count;
    if (chargeCount == 0)
        return;

    bool deleteCharges = false;
    string confirmText = "Are you sure you would like to delete this charge?"; // to be localized
    if (chargeCount > 1)
        confirmText = "Are you sure you would like to delete these charges?"; // to be localized
    deleteCharges = (MessageBox.Show(
                    confirmText,
                    "Confirm", // to be localized
                    MessageBoxButtons.YesNo,
                    MessageBoxIcon.Warning,
                    MessageBoxDefaultButton.Button2
                   ) == DialogResult.Yes);
    if (deleteCharges)
    {
        // SQLTransaction Start
        foreach (DataGridViewRow row in dgvAccount.SelectedRows)
        {
            //do Work    
        }
    }
}

Try:

printf("%04x",a);

• 0 - Left-pads the number with zeroes (0) instead of spaces, where padding is specified.
• 4 (width) - Minimum number of characters to be printed. If the value to be printed is shorter than this number, the result is right justified within this width by padding on the left with the pad character. By default this is a blank space, but the leading zero we used specifies a zero as the pad char. The value is not truncated even if the result is larger.
• x - Specifier for hexadecimal integer.

To add:

$arr["key"] = "value";

Then simply return $arr

Can't return directly like this way return $arr["key"] = "value";

The first way is the older standard. The second method was introduced in SQL-92, http://en.wikipedia.org/wiki/SQL. The complete standard can be viewed at http://www.contrib.andrew.cmu.edu/~shadow/sql/sql1992.txt .

It took many years before database companies adopted the SQL-92 standard.

So the reason why the second method is preferred, it is the SQL standard according the ANSI and ISO standards committee.

No, abstract class can never be instantiated.

ProgressDialog is deprecated from Android Oreo. Use ProgressBar instead

ProgressDialog progress = new ProgressDialog(this);
progress.setTitle("Loading");
progress.setMessage("Wait while loading...");
progress.setCancelable(false); // disable dismiss by tapping outside of the dialog
progress.show();
// To dismiss the dialog
progress.dismiss();

OR

ProgressDialog.show(this, "Loading", "Wait while loading...");

By the way, Spinner has a different meaning in Android. (It's like the select dropdown in HTML)

Do you merely want to print the string that way, or do you want that to be the internal representation of the string? If the latter, create it as a raw string by prefixing it with r: r"Hello\tWorld\nHello World".

>>> a = r"Hello\tWorld\nHello World"
>>> a # in the interpreter, this calls repr()
'Hello\\tWorld\\nHello World'
>>> print a
Hello\tWorld\nHello World

Also, \s is not an escape character, except in regular expressions, and then it still has a much different meaning than what you're using it for.

Objects are instances of classes. Classes are just the blueprints for objects. So given your class definition -

# Note the added (object) - this is the preferred way of creating new classes
class Student(object):
    name = "Unknown name"
    age = 0
    major = "Unknown major"

You can create a make_student function by explicitly assigning the attributes to a new instance of Student -

def make_student(name, age, major):
    student = Student()
    student.name = name
    student.age = age
    student.major = major
    return student

But it probably makes more sense to do this in a constructor (__init__) -

class Student(object):
    def __init__(self, name="Unknown name", age=0, major="Unknown major"):
        self.name = name
        self.age = age
        self.major = major

The constructor is called when you use Student(). It will take the arguments defined in the __init__ method. The constructor signature would now essentially be Student(name, age, major).

If you use that, then a make_student function is trivial (and superfluous) -

def make_student(name, age, major):
    return Student(name, age, major)

For fun, here is an example of how to create a make_student function without defining a class. Please do not try this at home.

def make_student(name, age, major):
    return type('Student', (object,),
                {'name': name, 'age': age, 'major': major})()

This question is a old one but it can help for others too.

Try this :

    li.setBackgroundColor(getResources().getColor(R.color.blue));

    or

    li.setBackgroundColor(getResources().getColor(android.R.color.red));

    or

    li.setBackgroundColor(Color.rgb(226, 11, 11));


    or
    li.setBackgroundColor(Color.RED)

There's no constants in JavaScript, but to declare a literal all you have to do is:

var myString = "Hello World";

I'm not sure what you mean by store them in a resource file; that's not a JavaScript concept.

i wanted to mention Jailbreak specifically (GitHub):

Jailbreak

Jailbreak is a tool for exporting certificates marked as non-exportable from the Windows certificate store. This can help when you need to extract certificates for backup or testing. You must have full access to the private key on the filesystem in order for jailbreak to work.

Prerequisites: Win32

I have encountered this recently, and in the most recent versions of Powershell there is a new BitsTransfer Module, which allows file transfers using BITS, and supports the use of the -Credential parameter.

The following sample shows how to use the BitsTransfer module to copy a file from a network share to a local machine, using a specified PSCredential object.

Import-Module bitstransfer
$cred = Get-Credential
$sourcePath = \\server\example\file.txt
$destPath = C:\Local\Destination\
Start-BitsTransfer -Source $sourcePath -Destination $destPath -Credential $cred

Another way to handle this is using the standard "net use" command. This command, however, does not support a "securestring" password, so after obtaining the credential object, you have to get a decrypted version of the password to pass to the "net use" command.

$cred = Get-Credential
$networkCred = $cred.GetNetworkCredential()
net use \\server\example\ $networkCred.Password /USER:$networkCred.UserName
Copy-Item \\server\example\file.txt C:\Local\Destination\

Geocoding through Javascript:
https://developers.google.com/maps/documentation/javascript/geocoding

You can add a form onsubmit handler, something like:

<form onsubmit="return validate();">

</form>


<script>function validate() {
 // check if input is bigger than 3
 var value = document.getElementById('titleeee').value;
 if (value.length < 3) {
   return false; // keep form from submitting
 }

 // else form is good let it submit, of course you will 
 // probably want to alert the user WHAT went wrong.

 return true;
}</script>

You have to call close() on the GZIPOutputStream before you attempt to read it. The final bytes of the file will only be written when the file is actually closed. (This is irrespective of any explicit buffering in the output stack. The stream only knows to compress and write the last bytes when you tell it to close. A flush() probably won't help ... though calling finish() instead of close() should work. Look at the javadocs.)

Here's the correct code (in Java);

package test;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;

public class GZipTest {

    public static void main(String[] args) throws
                FileNotFoundException, IOException {
        String name = "/tmp/test";
        GZIPOutputStream gz = new GZIPOutputStream(new FileOutputStream(name));
        gz.write(10);
        gz.close();       // Remove this to reproduce the reported bug
        System.out.println(new GZIPInputStream(new FileInputStream(name)).read());
    }
}

(I've not implemented resource management or exception handling / reporting properly as they are not relevant to the purpose of this code. Don't treat this as an example of "good code".)

You can do this 2 ways, via js or html (easist)

1. Via js

$('.carousel').carousel({
  interval: false,
});

That will make the auto sliding stop because there no Milliseconds added and will never slider next.

2. Via Html By adding data-interval="false" and removing data-ride="carousel"

<div id="carouselExampleCaptions" class="carousel slide" data-ride="carousel">

becomes:

<div id="carouselExampleCaptions" class="carousel slide" data-interval="false">

updated based on @webMan's comment

With reference to https://support.microsoft.com/en-us/help/139444/how-to-remove-duplicate-rows-from-a-table-in-sql-server

The idea of removing duplicate involves

• a) Protecting those rows that are not duplicate
• b) Retain one of the many rows that qualified together as duplicate.

Step-by-step

• 1) First identify the rows those satisfy the definition of duplicate and insert them into temp table, say #tableAll .
• 2) Select non-duplicate(single-rows) or distinct rows into temp table say #tableUnique.
• 3) Delete from source table joining #tableAll to delete the duplicates.
• 4) Insert into source table all the rows from #tableUnique.
• 5) Drop #tableAll and #tableUnique

Just adding a new line worked for me if you're to store the markdown in a JavaScript variable. like so

let markdown = `
    1. Apple
    2. Mango
     this is juicy
    3. Orange
`

overflow-y:scroll is correct, but you should use it with the html tag, not body or else you get a double scrollbar in IE 7
So the correct css would be:

html {
  overflow-y: scroll;
}

In Ansible >1.4 you can actually specify a remote user at the task level which should allow you to login as that user and execute that command without resorting to sudo. If you can't login as that user then the sudo_user solution will work too.

If you get an OutOfMemoryError then it's usually too late to call the garbage collector...

Here is quote from Android Developer:

Most of the time, garbage collection occurs because of tons of small, short-lived objects and some garbage collectors, like generational garbage collectors, can optimize the collection of these objects so that the application does not get interrupted too often. The Android garbage collector is unfortunately not able to perform such optimizations and the creation of short-lived objects in performance critical code paths is thus very costly for your application.

So to my understanding, there is no urgent need to call the gc. It's better to spend more effort in avoiding the unnecessary creation of objects (like creation of objects inside loops)

This may have changed since the question was asked, but there is a difference between stopping an instance and terminating an instance.

If your instance is EBS-based, it can be stopped. It will remain in your account, but you will not be charged for it (you will continue to be charged for EBS storage associated with the instance and unused Elastic IP addresses). You can re-start the instance at any time.

If the instance is terminated, it will be deleted from your account. You’ll be charged for any remaining EBS volumes, but by default the associated EBS volume will be deleted. This can be configured when you create the instance using the command-line EC2 API Tools.

Since the only noise terminals tend to make is the bell and if you want it off everywhere, the very simplest way to do it for bash on Windows:

1. Mash backspace a bunch at the prompt
2. Right click sound icon and choose Open Volume Mixer
3. Lower volume on Console Window Host to zero

The here package provides the here() function, which returns your project root directory based on some heuristics.

Not the perfect solution, since it doesn't find the location of the script, but it suffices for some purposes so I thought I'd put it here.

• Right click your project in Solution Explorer and select Properties from the menu
• Go to Configuration Properties -> Debugging
• Set the Command Arguments in the property list.

Just use the time stamp as date:

SELECT * FROM Cases WHERE date(created_at)='2013-05-01' 

i was using

objectName.addEventListener('click', function() {
event.preventDefault();
}

but its show error "event is undefined" so in this case use event parameter like

objectName.addEventListener('click', function(event) {
event.preventDefault();
}

now its works fine

Android has a method of chaining views together in its constraint based layout system that I wanted to mimic. Searches brought me here but none of the answers quite worked. I didn't want to use StackViews because they tend to cause me more grief down the line than they save up front. I ended up creating a solution that used UILayoutGuides placed between the views. Controlling their width's allows different types of distributions, chain styles in Android parlance. The function accepts a leading and trailing anchor instead of a parent view. This allows the chain to be placed between two arbitrary views rather than distributed inside of the parent view. It does use UILayoutGuide which is only available in iOS 9+ but that shouldn't be a problem anymore.

public enum LayoutConstraintChainStyle {
    case spread //Evenly distribute between the anchors
    case spreadInside //Pin the first & last views to the sides and then evenly distribute
    case packed //The views have a set space but are centered between the anchors.
}

public extension NSLayoutConstraint {

    static func chainHorizontally(views: [UIView],
                                  leadingAnchor: NSLayoutXAxisAnchor,
                                  trailingAnchor: NSLayoutXAxisAnchor,
                                  spacing: CGFloat = 0.0,
                                  style: LayoutConstraintChainStyle = .spread) -> [NSLayoutConstraint] {
    var constraints = [NSLayoutConstraint]()
    guard views.count > 1 else { return constraints }
    guard let first = views.first, let last = views.last, let superview = first.superview else { return constraints }

    //Setup the chain of views
    var distributionGuides = [UILayoutGuide]()
    var previous = first
    let firstGuide = UILayoutGuide()
    superview.addLayoutGuide(firstGuide)
    distributionGuides.append(firstGuide)
    firstGuide.identifier = "ChainDistribution\(distributionGuides.count)"
    constraints.append(firstGuide.leadingAnchor.constraint(equalTo: leadingAnchor))
    constraints.append(first.leadingAnchor.constraint(equalTo: firstGuide.trailingAnchor, constant: spacing))
    views.dropFirst().forEach { view in
        let g = UILayoutGuide()
        superview.addLayoutGuide(g)
        distributionGuides.append(g)
        g.identifier = "ChainDistribution\(distributionGuides.count)"
        constraints.append(contentsOf: [
            g.leadingAnchor.constraint(equalTo: previous.trailingAnchor),
            view.leadingAnchor.constraint(equalTo: g.trailingAnchor)
        ])
        previous = view
    }
    let lastGuide = UILayoutGuide()
    superview.addLayoutGuide(lastGuide)
    constraints.append(contentsOf: [lastGuide.leadingAnchor.constraint(equalTo: last.trailingAnchor),
                                    lastGuide.trailingAnchor.constraint(equalTo: trailingAnchor)])
    distributionGuides.append(lastGuide)

    //Space the according to the style.
    switch style {
    case .packed:
        if let first = distributionGuides.first, let last = distributionGuides.last {
            constraints.append(first.widthAnchor.constraint(greaterThanOrEqualToConstant: spacing))
            constraints.append(last.widthAnchor.constraint(greaterThanOrEqualToConstant: spacing))
            constraints.append(last.widthAnchor.constraint(equalTo: first.widthAnchor))
            constraints.append(contentsOf:
                distributionGuides.dropFirst().dropLast()
                    .map { $0.widthAnchor.constraint(equalToConstant: spacing) }
                )
        }
    case .spread:
        if let first = distributionGuides.first {
            constraints.append(contentsOf:
                distributionGuides.dropFirst().map { $0.widthAnchor.constraint(equalTo: first.widthAnchor) })
        }
    case .spreadInside:
        if let first = distributionGuides.first, let last = distributionGuides.last {
            constraints.append(first.widthAnchor.constraint(equalToConstant: spacing))
            constraints.append(last.widthAnchor.constraint(equalToConstant: spacing))
            let innerGuides = distributionGuides.dropFirst().dropLast()
            if let key = innerGuides.first {
                constraints.append(contentsOf:
                    innerGuides.dropFirst().map { $0.widthAnchor.constraint(equalTo: key.widthAnchor) }
                )
            }
        }
    }

    return constraints
}

Another option is to suppress the warning individually:

xmlns:tools="http://schemas.android.com/tools"  (usually inserted automatically)
tools:ignore="contentDescription"

Example:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" 
    tools:ignore="contentDescription" >

       <ImageView
            android:layout_width="50dp"
            android:layout_height="match_parent"
            android:adjustViewBounds="true"
            android:padding="5dp"
            android:src="@drawable/icon" />

Dynamic Programming is often called Memoization!

1.Memoization is the top-down technique(start solving the given problem by breaking it down) and dynamic programming is a bottom-up technique(start solving from the trivial sub-problem, up towards the given problem)

2.DP finds the solution by starting from the base case(s) and works its way upwards. DP solves all the sub-problems, because it does it bottom-up

Unlike Memoization, which solves only the needed sub-problems

1. DP has the potential to transform exponential-time brute-force solutions into polynomial-time algorithms.

2. DP may be much more efficient because its iterative

On the contrary, Memoization must pay for the (often significant) overhead due to recursion.

To be more simple, Memoization uses the top-down approach to solve the problem i.e. it begin with core(main) problem then breaks it into sub-problems and solve these sub-problems similarly. In this approach same sub-problem can occur multiple times and consume more CPU cycle, hence increase the time complexity. Whereas in Dynamic programming same sub-problem will not be solved multiple times but the prior result will be used to optimize the solution.

Take a look at the java.text.MessageFormat class, MessageFormat takes a set of objects, formats them, then inserts the formatted strings into the pattern at the appropriate places.

Object[] params = new Object[]{"hello", "!"};
String msg = MessageFormat.format("{0} world {1}", params);

Converting to double can be done by casting an int to a double:

You can convert an int to a double by using this mechnism like so:

int i = 3; // i is 3
double d = (double) i; // d = 3.0

Alternative (using Java's automatic type recognition):

double d = 1.0 * i; // d = 3.0

Implementing this in your code would be something like:

double firstSolution = ((double)(b1 * a22 - b2 * a12) / (double)(a11 * a22 - a12 * a21));
double secondSolution = ((double)(b2 * a11 - b1 * a21) / (double)(a11 * a22 - a12 * a21));

Alternatively you can use a hard-parameter of type double (1.0) to have java to the work for you, like so:

double firstSolution = ((1.0 * (b1 * a22 - b2 * a12)) / (1.0 * (a11 * a22 - a12 * a21)));
double secondSolution = ((1.0 * (b2 * a11 - b1 * a21)) / (1.0 * (a11 * a22 - a12 * a21)));

Good luck.

In Android 26.0.0 PercentRelativeLayout has been deprecated.

The best way to solve it is now with ConstraintLayout like this:

<android.support.constraint.ConstraintLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content">

    <ImageView android:layout_width="match_parent"
               android:layout_height="0dp"
               android:scaleType="centerCrop"
               android:src="@drawable/you_image"                       
               app:layout_constraintDimensionRatio="1:1"/>


</android.support.constraint.ConstraintLayout>

Here is a tutorial on how to add ConstraintLayout to your project.

To reduce SDK specific versions, you could simply do this: (replace '#' to '0x')

Notification notification = new NotificationCompat.Builder(this);
notification.setSmallIcon(R.drawable.icon_transperent);
notification.setColor(0x169AB9); //for color: #169AB9

Here's how:

// Create an array with room for 100 integers
int[] nums = new int[100];

// Fill it with numbers using a for-loop
for (int i = 0; i < nums.length; i++)
    nums[i] = i + 1;  // +1 since we want 1-100 and not 0-99

// Compute sum
int sum = 0;
for (int n : nums)
    sum += n;

// Print the result (5050)
System.out.println(sum);

FYI, the list of operators (containing like and all others) is in code:

/vendor/laravel/framework/src/Illuminate/Database/Query/Builder.php

protected $operators = array(
    '=', '<', '>', '<=', '>=', '<>', '!=',
    'like', 'not like', 'between', 'ilike',
    '&', '|', '^', '<<', '>>',
    'rlike', 'regexp', 'not regexp',
);

disclaimer:

Joel Larson's answer is correct. Got my upvote.

I'm hoping this answer sheds more light on what's available via the Eloquent ORM (points people in the right direct). Whilst a link to documentation would be far better, that link has proven itself elusive.

declare @sexo as char(1)

select @sexo='F'

select * from pessoa

where isnull(Sexo,0) =isnull(@Sexo,0)

Using & operator, don't forget to wrap the sub-statements with ():

males = df[(df[Gender]=='Male') & (df[Year]==2014)]

To store your dataframes in a dict using a for loop:

from collections import defaultdict
dic={}
for g in ['male', 'female']:
  dic[g]=defaultdict(dict)
  for y in [2013, 2014]:
    dic[g][y]=df[(df[Gender]==g) & (df[Year]==y)] #store the DataFrames to a dict of dict

EDIT:

A demo for your getDF:

def getDF(dic, gender, year):
  return dic[gender][year]

print genDF(dic, 'male', 2014)

Transparency is a property outside the color itself, also known as alpha component. You can't code it as RGB.

If you want a transparent background, you can do this:

background: transparent;

Additionally, I don't know if it might be helpful or not but, you could set the opacity property:

.half{
  opacity: 0.5;
  filter: alpha(opacity=50);
}

You need both in order to get it working in IE and all other decent browsers.

HTML Code

<input type="file" name="image" id="uploadImage" size="30" />
<input type="submit" name="upload"  class="send_upload" value="upload" />

jQuery Code using bind method

$(document).ready(function() {
    $('#upload').bind("click",function() 
    { if(!$('#uploadImage').val()){
                alert("empty");
                return false;} });  });

If this occurs IE intranet only, check compatibility settings and uncheck "Display intranet sites in Compatibility mode" .

Bitmap bitmap = ((BitmapDrawable)image.getDrawable()).getBitmap();

I've created an example to show how to. Updated state definition would be:

  $stateProvider
    .state('home', {
      url: '/:foo?bar',
      views: {
        '': {
          templateUrl: 'tpl.home.html',
          controller: 'MainRootCtrl'

        },
        ...
      }

And this would be the controller:

.controller('MainRootCtrl', function($scope, $state, $stateParams) {
    //..
    var foo = $stateParams.foo; //getting fooVal
    var bar = $stateParams.bar; //getting barVal
    //..
    $scope.state = $state.current
    $scope.params = $stateParams; 
})

What we can see is that the state home now has url defined as:

url: '/:foo?bar',

which means, that the params in url are expected as

/fooVal?bar=barValue

These two links will correctly pass arguments into the controller:

<a ui-sref="home({foo: 'fooVal1', bar: 'barVal1'})">
<a ui-sref="home({foo: 'fooVal2', bar: 'barVal2'})">

Also, the controller does consume $stateParams instead of $stateParam.

Link to doc:

• URL Parameters

You can check it here

params : {}

There is also new, more granular setting params : {}. As we've already seen, we can declare parameters as part of url. But with params : {} configuration - we can extend this definition or even introduce paramters which are not part of the url:

.state('other', {
    url: '/other/:foo?bar',
    params: { 
        // here we define default value for foo
        // we also set squash to false, to force injecting
        // even the default value into url
        foo: {
          value: 'defaultValue',
          squash: false,
        },
        // this parameter is now array
        // we can pass more items, and expect them as []
        bar : { 
          array : true,
        },
        // this param is not part of url
        // it could be passed with $state.go or ui-sref 
        hiddenParam: 'YES',
      },
    ...

Settings available for params are described in the documentation of the $stateProvider

Below is just an extract

• value - {object|function=}: specifies the default value for this parameter. This implicitly sets this parameter as optional...
• array - {boolean=}: (default: false) If true, the param value will be treated as an array of values.
• squash - {bool|string=}: squash configures how a default parameter value is represented in the URL when the current parameter value is the same as the default value.

We can call these params this way:

// hidden param cannot be passed via url
<a href="#/other/fooVal?bar=1&amp;bar=2">
// default foo is skipped
<a ui-sref="other({bar: [4,5]})">

I had this problem today. I fixed it being being explict about my require

gem 'uglifier', '>= 1.0.3', require: 'uglifier'

I had mine still in the assets group.

Array slicing like in Python (From the rebash library):

array_slice() {
    local __doc__='
    Returns a slice of an array (similar to Python).

    From the Python documentation:
    One way to remember how slices work is to think of the indices as pointing
    between elements, with the left edge of the first character numbered 0.
    Then the right edge of the last element of an array of length n has
    index n, for example:
    ```
    +---+---+---+---+---+---+
    | 0 | 1 | 2 | 3 | 4 | 5 |
    +---+---+---+---+---+---+
    0   1   2   3   4   5   6
    -6  -5  -4  -3  -2  -1
    ```

    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 1:-2 "${a[@]}")
    1 2 3
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 0:1 "${a[@]}")
    0
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice 1:1 "${a[@]}")" ] && echo empty
    empty
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice 2:1 "${a[@]}")" ] && echo empty
    empty
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice -2:-3 "${a[@]}")" ] && echo empty
    empty
    >>> [ -z "$(array.slice -2:-2 "${a[@]}")" ] && echo empty
    empty

    Slice indices have useful defaults; an omitted first index defaults to
    zero, an omitted second index defaults to the size of the string being
    sliced.
    >>> local a=(0 1 2 3 4 5)
    >>> # from the beginning to position 2 (excluded)
    >>> echo $(array.slice 0:2 "${a[@]}")
    >>> echo $(array.slice :2 "${a[@]}")
    0 1
    0 1

    >>> local a=(0 1 2 3 4 5)
    >>> # from position 3 (included) to the end
    >>> echo $(array.slice 3:"${#a[@]}" "${a[@]}")
    >>> echo $(array.slice 3: "${a[@]}")
    3 4 5
    3 4 5

    >>> local a=(0 1 2 3 4 5)
    >>> # from the second-last (included) to the end
    >>> echo $(array.slice -2:"${#a[@]}" "${a[@]}")
    >>> echo $(array.slice -2: "${a[@]}")
    4 5
    4 5

    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -4:-2 "${a[@]}")
    2 3

    If no range is given, it works like normal array indices.
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -1 "${a[@]}")
    5
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -2 "${a[@]}")
    4
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 0 "${a[@]}")
    0
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 1 "${a[@]}")
    1
    >>> local a=(0 1 2 3 4 5)
    >>> array.slice 6 "${a[@]}"; echo $?
    1
    >>> local a=(0 1 2 3 4 5)
    >>> array.slice -7 "${a[@]}"; echo $?
    1

I found a mod_rewrite solution that works well for both proxied and unproxied servers.

If you are using CloudFlare, AWS Elastic Load Balancing, Heroku, OpenShift or any other Cloud/PaaS solution and you are experiencing redirect loops with normal HTTPS redirects, try the following snippet instead.

RewriteEngine On

# If we receive a forwarded http request from a proxy...
RewriteCond %{HTTP:X-Forwarded-Proto} =http [OR]

# ...or just a plain old http request directly from the client
RewriteCond %{HTTP:X-Forwarded-Proto} =""
RewriteCond %{HTTPS} !=on

# Redirect to https version
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

If you get a python error like this:

AttributeError: 'str' object has no attribute 'some_method'

You probably poisoned your object accidentally by overwriting your object with a string.

How to reproduce this error in python with a few lines of code:

#!/usr/bin/env python
import json
def foobar(json):
    msg = json.loads(json)

foobar('{"batman": "yes"}')

Run it, which prints:

AttributeError: 'str' object has no attribute 'loads'

But change the name of the variablename, and it works fine:

#!/usr/bin/env python
import json
def foobar(jsonstring):
    msg = json.loads(jsonstring)

foobar('{"batman": "yes"}')

This error is caused when you tried to run a method within a string. String has a few methods, but not the one you are invoking. So stop trying to invoke a method which String does not define and start looking for where you poisoned your object.

Along the lines of Sainath S.R's comment above, I was able to set a js object property name from a variable in Google Apps Script (which does not support ES6 yet) by defining the object then defining another key/value outside of the object:

var salesperson = ...

var mailchimpInterests = { 
        "aGroupId": true,
    };

mailchimpInterests[salesperson] = true;

Graph algorithms like Dijkstra's algorithm will not work because the graph is enormous.

This argument doesn't necessarily hold because Dijkstra will not usually look at the complete graph but rather just a very small subset (the better interconnected the graph, the smaller this subset).

Dijkstra may actually perform rather well for well-behaved graphs. On the other hand, with careful parametrization A* will always perform just as good, or better. Have you already tried how it would perform on your data?

That said, I'd also be very interested to hear about other peoples' experiences. Of course, prominent examples like Google Map's search are particularly interesting. I could imagine something like a directed nearest neighbour heuristic.

The installation procedure creates a user account called postgres that is associated with the default Postgres role. In order to use Postgres, you can log into that account. But if not explicitly specified the rails app looks for a different role, more particularly the role having your unix username which might not be created in the postgres roles.

To overcome that, you can create a new role, first by switching over to the default role postgres which was created during installation

sudo -i -u postgres

After you are logged in to the postgres account, you can create a new user by the command:

createuser --interactive

This will prompt you with some choices and, based on your responses, execute the correct Postgres commands to create a user.

Pass over a role name and some permissions and the role is created, you can then migrate your db

You can do $this->getRequest()->query->all(); to get all GET params and $this->getRequest()->request->all(); to get all POST params.

So in your case:

$params = $this->getRequest()->request->all();
$params['value1'];
$params['value2'];

This is my solution to create a fullscreen div, using pure css. It displays a full screen div that is persistent on scrolling. And if the page content fits on the screen, the page won't show a scroll-bar.

This function reads a CSV file of 15MB and copies its content into a sheet in about 3 secs. What is probably taking a lot of time in your code is the fact that you copy data cell by cell instead of putting the whole content at once.

If you want to run a cron every n minutes, there are a few possible options depending on the value of n.

n divides 60 (1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30)

Here, the solution is straightforward by making use of the / notation:

# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7)
# |  |  |  |  |
# *  *  *  *  *   command to be executed
m-59/n  *  *  *  *   command

In the above, n represents the value n and m represents a value smaller than n or *. This will execute the command at the minutes m,m+n,m+2n,...

n does NOT divide 60

If n does not divide 60, you cannot do this cleanly with cron but it is possible. To do this you need to put a test in the cron where the test checks the time. This is best done when looking at the UNIX timestamp, the total seconds since 1970-01-01 00:00:00 UTC. Let's say we want to start to run the command the first time when Marty McFly arrived in Riverdale and then repeat it every n minutes later.

% date -d '2015-10-21 07:28:00' +%s 
1445412480

For a cronjob to run every 42nd minute after `2015-10-21 07:28:00', the crontab would look like this:

# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7)
# |  |  |  |  |
# *  *  *  *  *   command to be executed
  *  *  *  *  *   minutetestcmd "2015-10-21 07:28:00" 42 && command

with minutetestcmd defined as

#!/usr/bin/env bash
starttime=$(date -d "$1" "+%s")
# return UTC time
now=$(date "+%s")
# get the amount of minutes (using integer division to avoid lag)
minutes=$(( (now - starttime) / 60 ))
# set the modulo
modulo=$2
# do the test
(( now >= starttime )) && (( minutes % modulo == 0 ))

Remark: UNIX time is not influenced by leap seconds

Remark: cron has no sub-second accuracy

@Michael Yagudaev 's answer works for me.

But the original answer did not chain the wrapped promise with .catch() to handle reject handling, here is my improvement on top of @Michael Yagudaev's answer:

const makeCancelablePromise = promise => {
  let hasCanceled = false;
  const wrappedPromise = new Promise((resolve, reject) => {
    promise
      .then(val => (hasCanceled ? reject({ isCanceled: true }) : resolve(val)))
      .catch(
        error => (hasCanceled ? reject({ isCanceled: true }) : reject(error))
      );
  });

  return {
    promise: wrappedPromise,
    cancel() {
      hasCanceled = true;
    }
  };
};

// Example Usage:
const cancelablePromise = makeCancelable(
  new Promise((rs, rj) => {
    /*do something*/
  })
);
cancelablePromise.promise.then(() => console.log('resolved')).catch(err => {
  if (err.isCanceled) {
    console.log('Wrapped promise canceled');
    return;
  }
  console.log('Promise was not canceled but rejected due to errors: ', err);
});
cancelablePromise.cancel();

In my experience, using System.gc() is effectively a platform-specific form of optimization (where "platform" is the combination of hardware architecture, OS, JVM version and possible more runtime parameters such as RAM available), because its behaviour, while roughly predictable on a specific platform, can (and will) vary considerably between platforms.

Yes, there are situations where System.gc() will improve (perceived) performance. On example is if delays are tolerable in some parts of your app, but not in others (the game example cited above, where you want GC to happen at the start of a level, not during the level).

However, whether it will help or hurt (or do nothing) is highly dependent on the platform (as defined above).

So I think it is valid as a last-resort platform-specific optimization (i.e. if other performance optimizations are not enough). But you should never call it just because you believe it might help(without specific benchmarks), because chances are it will not.

This enhances the accepted answer by decorating the $http service with an abort method as follows ...

'use strict';
angular.module('admin')
  .config(["$provide", function ($provide) {

$provide.decorator('$http', ["$delegate", "$q", function ($delegate, $q) {
  var getFn = $delegate.get;
  var cancelerMap = {};

  function getCancelerKey(method, url) {
    var formattedMethod = method.toLowerCase();
    var formattedUrl = encodeURI(url).toLowerCase().split("?")[0];
    return formattedMethod + "~" + formattedUrl;
  }

  $delegate.get = function () {
    var cancelerKey, canceler, method;
    var args = [].slice.call(arguments);
    var url = args[0];
    var config = args[1] || {};
    if (config.timeout == null) {
      method = "GET";
      cancelerKey = getCancelerKey(method, url);
      canceler = $q.defer();
      cancelerMap[cancelerKey] = canceler;
      config.timeout = canceler.promise;
      args[1] = config;
    }
    return getFn.apply(null, args);
  };

  $delegate.abort = function (request) {
    console.log("aborting");
    var cancelerKey, canceler;
    cancelerKey = getCancelerKey(request.method, request.url);
    canceler = cancelerMap[cancelerKey];

    if (canceler != null) {
      console.log("aborting", cancelerKey);

      if (request.timeout != null && typeof request.timeout !== "number") {

        canceler.resolve();
        delete cancelerMap[cancelerKey];
      }
    }
  };

  return $delegate;
}]);
  }]);

WHAT IS THIS CODE DOING?

To cancel a request a "promise" timeout must be set. If no timeout is set on the HTTP request then the code adds a "promise" timeout. (If a timeout is set already then nothing is changed).

However, to resolve the promise we need a handle on the "deferred". We thus use a map so we can retrieve the "deferred" later. When we call the abort method, the "deferred" is retrieved from the map and then we call the resolve method to cancel the http request.

Hope this helps someone.

LIMITATIONS

Currently this only works for $http.get but you can add code for $http.post and so on

HOW TO USE ...

You can then use it, for example, on state change, as follows ...

rootScope.$on('$stateChangeStart', function (event, toState, toParams) {
  angular.forEach($http.pendingRequests, function (request) {
        $http.abort(request);
    });
  });

It looks like you indented so_far = new too much. Try this:

if guess in word:
    print("\nYes!", guess, "is in the word!")

    # Create a new variable (so_far) to contain the guess
    new = ""
    i = 0
    for i in range(len(word)):
        if guess == word[i]:
            new += guess
        else:
            new += so_far[i]
    so_far = new # unindented this

There is no one built-in function in C++ to do this. If you'd like to replace all instances of one substring with another, you can do so by intermixing calls to string::find and string::replace. For example:

size_t index = 0;
while (true) {
     /* Locate the substring to replace. */
     index = str.find("abc", index);
     if (index == std::string::npos) break;

     /* Make the replacement. */
     str.replace(index, 3, "def");

     /* Advance index forward so the next iteration doesn't pick it up as well. */
     index += 3;
}

In the last line of this code, I've incremented index by the length of the string that's been inserted into the string. In this particular example - replacing "abc" with "def" - this is not actually necessary. However, in a more general setting, it is important to skip over the string that's just been replaced. For example, if you want to replace "abc" with "abcabc", without skipping over the newly-replaced string segment, this code would continuously replace parts of the newly-replaced strings until memory was exhausted. Independently, it might be slightly faster to skip past those new characters anyway, since doing so saves some time and effort by the string::find function.

Hope this helps!

As of CSS3, the spec has changed, allowing for only a single font-style. A comma-separated list (per CSS2) will be treated as if it were normal and override any earlier (default) entry. This will make fonts defined in this way appear italic permanently.

@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans.ttf");
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Bold.ttf");
    font-weight: bold;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Oblique.ttf");
    font-style: italic;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-BoldOblique.ttf");
    font-weight: bold;
    font-style: italic;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Oblique.ttf");
    font-style: oblique;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-BoldOblique.ttf");
    font-weight: bold;
    font-style: oblique;
}

In most cases, italic will probably be sufficient and oblique rules won't be necessary if you take care to define whichever you will use and stick to it.

Came here looking for help as got same error running a statement listed below while going through a Udemy course:

INSERT INTO departments (department_id, department_name)
                  values( &dpet_id, '&dname');  

I'd been able to run statements with substitution variables before. Comment by Charles Burns about possibility of server reaching some threshold while recreating the variables prompted me to log out and restart the SQL Developer. The statement ran fine after logging back in.

Thought I'd share for anyone else venturing here with a limited scope issue as mine.

I think functional requirement is from client to developer side that is regarding functionality to the user by the software and non-functional requirement is from developer to client i.e. the requirement is not given by client but it is provided by developer to run the system smoothly e.g. safety, security, flexibility, scalability, availability, etc.

It's baffling that they included a toLocaleString but not a parse method. At least toLocaleString without arguments is well supported in IE6+.

For a i18n solution, I came up with this:

First detect the user's locale decimal separator:

var decimalSeparator = 1.1;
decimalSeparator = decimalSeparator.toLocaleString().substring(1, 2);

Then normalize the number if there's more than one decimal separator in the String:

var pattern = "([" + decimalSeparator + "])(?=.*\\1)";separator
var formatted = valor.replace(new RegExp(pattern, "g"), "");

Finally, remove anything that is not a number or a decimal separator:

formatted = formatted.replace(new RegExp("[^0-9" + decimalSeparator + "]", "g"), '');
return Number(formatted.replace(decimalSeparator, "."));

Keep in mind that it's the user that is running the oracle database that must have write permissions to the /defaultdir directory, not the user logged into oracle. Typically you're running the database as the user "Oracle". It's not the same user (necessarily) that you created the external table with.

Check your directory permissions, too.

Some of the other answers here inspired me to write a script for automating the mixed sequential execution of SQL tasks using SQLPLUS along with shell commands for a project, a process that was previously manually done. Maybe this (highly sanitized) example will be useful to someone else:

#!/bin/bash
acreds="user_a/supergreatpassword"
bcreds="user_b/anothergreatpassword"
hoststring='fancyoraclehoststring'

runsql () {
  # param 1 is $1
sqlplus -S /nolog << EOF
CONNECT $1@$hoststring;
whenever sqlerror exit sql.sqlcode;
set echo off
set heading off
$2
exit;
EOF
}

echo "TS::$(date): Starting SCHEM_A.PROC_YOU_NEED()..."
runsql "$acreds" "execute SCHEM_A.PROC_YOU_NEED();"

echo "TS::$(date): Starting superusefuljob..."
/var/scripts/superusefuljob.sh

echo "TS::$(date): Starting SCHEM_B.SECRET_B_PROC()..."
runsql "$bcreds" "execute SCHEM_B.SECRET_B_PROC();"

echo "TS::$(date): DONE"

runsql allows you to pass a credential string as the first argument, and any SQL you need as the second argument. The variables containing the credentials are included for illustration, but for security I actually source them from another file. If you wanted to handle multiple database connections, you could easily modify the function to accept the hoststring as an additional parameter.

With Guava, you can use Iterables.concat(Iterable<T> ...), it creates a live view of all the iterables, concatenated into one (if you change the iterables, the concatenated version also changes). Then wrap the concatenated iterable with Iterables.unmodifiableIterable(Iterable<T>) (I hadn't seen the read-only requirement earlier).

From the Iterables.concat( .. ) JavaDocs:

Combines multiple iterables into a single iterable. The returned iterable has an iterator that traverses the elements of each iterable in inputs. The input iterators are not polled until necessary. The returned iterable's iterator supports remove() when the corresponding input iterator supports it.

While this doesn't explicitly say that this is a live view, the last sentence implies that it is (supporting the Iterator.remove() method only if the backing iterator supports it is not possible unless using a live view)

Sample Code:

final List<Integer> first  = Lists.newArrayList(1, 2, 3);
final List<Integer> second = Lists.newArrayList(4, 5, 6);
final List<Integer> third  = Lists.newArrayList(7, 8, 9);
final Iterable<Integer> all =
    Iterables.unmodifiableIterable(
        Iterables.concat(first, second, third));
System.out.println(all);
third.add(9999999);
System.out.println(all);

Output:

[1, 2, 3, 4, 5, 6, 7, 8, 9]
[1, 2, 3, 4, 5, 6, 7, 8, 9, 9999999]

Since sizeWithFont is deprecated, I'm just going to update my original answer to using Swift 4 and .size

//: Playground - noun: a place where people can play

import UIKit

if let font = UIFont(name: "Helvetica", size: 24) {
   let fontAttributes = [NSAttributedStringKey.font: font]
   let myText = "Your Text Here"
   let size = (myText as NSString).size(withAttributes: fontAttributes)
}

The size should be the onscreen size of "Your Text Here" in points.

You can use this javascript code to redirect after a specific time. Hope it will work.

setRedirectTime(function () 
{
   window.location.href= 'https://www.google.com'; // the redirect URL will be here

},10000); // 10 seconds

In my case, if I remove the the contentType, I get the Internal Server Error.

This is what I got working after multiple attempts:

var request =  $.ajax({
    type: 'POST',
    url: '/ControllerName/ActionName' ,
    contentType: 'application/json; charset=utf-8',
    data: JSON.stringify({ projId: 1, userId:1 }), //hard-coded value used for simplicity
    dataType: 'json'
});

request.done(function(msg) {
    alert(msg);
});

request.fail(function (jqXHR, textStatus, errorThrown) {
    alert("Request failed: " + jqXHR.responseStart +"-" + textStatus + "-" + errorThrown);
});

And this is the controller code:

public JsonResult ActionName(int projId, int userId)
{
    var obj = new ClassName();

    var result = obj.MethodName(projId, userId); // variable used for readability
    return Json(result, JsonRequestBehavior.AllowGet);
}

Please note, the case of ASP.NET is little different, we have to apply JSON.stringify() to the data as mentioned in the update of this answer.

A SOAP request is an XML file consisting of the parameters you are sending to the server.

The SOAP response is equally an XML file, but now with everything the service wants to give you.

Basically the WSDL is a XML file that explains the structure of those two XML.

To implement simple SOAP clients in Java, you can use the SAAJ framework (it is shipped with JSE 1.6 and above):

SOAP with Attachments API for Java (SAAJ) is mainly used for dealing directly with SOAP Request/Response messages which happens behind the scenes in any Web Service API. It allows the developers to directly send and receive soap messages instead of using JAX-WS.

See below a working example (run it!) of a SOAP web service call using SAAJ. It calls this web service.

import javax.xml.soap.*;

public class SOAPClientSAAJ {

    // SAAJ - SOAP Client Testing
    public static void main(String args[]) {
        /*
            The example below requests from the Web Service at:
             http://www.webservicex.net/uszip.asmx?op=GetInfoByCity


            To call other WS, change the parameters below, which are:
             - the SOAP Endpoint URL (that is, where the service is responding from)
             - the SOAP Action

            Also change the contents of the method createSoapEnvelope() in this class. It constructs
             the inner part of the SOAP envelope that is actually sent.
         */
        String soapEndpointUrl = "http://www.webservicex.net/uszip.asmx";
        String soapAction = "http://www.webserviceX.NET/GetInfoByCity";

        callSoapWebService(soapEndpointUrl, soapAction);
    }

    private static void createSoapEnvelope(SOAPMessage soapMessage) throws SOAPException {
        SOAPPart soapPart = soapMessage.getSOAPPart();

        String myNamespace = "myNamespace";
        String myNamespaceURI = "http://www.webserviceX.NET";

        // SOAP Envelope
        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration(myNamespace, myNamespaceURI);

            /*
            Constructed SOAP Request Message:
            <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:myNamespace="http://www.webserviceX.NET">
                <SOAP-ENV:Header/>
                <SOAP-ENV:Body>
                    <myNamespace:GetInfoByCity>
                        <myNamespace:USCity>New York</myNamespace:USCity>
                    </myNamespace:GetInfoByCity>

            */

        // SOAP Body
        SOAPBody soapBody = envelope.getBody();
        SOAPElement soapBodyElem = soapBody.addChildElement("GetInfoByCity", myNamespace);
        SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("USCity", myNamespace);
        soapBodyElem1.addTextNode("New York");
    }

    private static void callSoapWebService(String soapEndpointUrl, String soapAction) {
        try {
            // Create SOAP Connection
            SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
            SOAPConnection soapConnection = soapConnectionFactory.createConnection();

            // Send SOAP Message to SOAP Server
            SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(soapAction), soapEndpointUrl);

            // Print the SOAP Response
            System.out.println("Response SOAP Message:");
            soapResponse.writeTo(System.out);
            System.out.println();

            soapConnection.close();
        } catch (Exception e) {
            System.err.println("\nError occurred while sending SOAP Request to Server!\nMake sure you have the correct endpoint URL and SOAPAction!\n");
            e.printStackTrace();
        }
    }

    private static SOAPMessage createSOAPRequest(String soapAction) throws Exception {
        MessageFactory messageFactory = MessageFactory.newInstance();
        SOAPMessage soapMessage = messageFactory.createMessage();

        createSoapEnvelope(soapMessage);

        MimeHeaders headers = soapMessage.getMimeHeaders();
        headers.addHeader("SOAPAction", soapAction);

        soapMessage.saveChanges();

        /* Print the request message, just for debugging purposes */
        System.out.println("Request SOAP Message:");
        soapMessage.writeTo(System.out);
        System.out.println("\n");

        return soapMessage;
    }

}

In one controller, you can do:

$rootScope.$broadcast('eventName', data);

and listen to the event in another:

$scope.$on('eventName', function (event, data) {...});

Use setValue method of Range class to set the value of particular cell.

function storeValue() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  // ss is now the spreadsheet the script is associated with
  var sheet = ss.getSheets()[0]; // sheets are counted starting from 0
  // sheet is the first worksheet in the spreadsheet
  var cell = sheet.getRange("B2"); 
  cell.setValue(100);
}

You can also select a cell using row and column numbers.

var cell = sheet.getRange(2, 3); // here cell is C2

It's also possible to set value of multiple cells at once.

var values = [
  ["2.000", "1,000,000", "$2.99"]
];

var range = sheet.getRange("B2:D2");
range.setValues(values);

If you have Java 7 so include the below following snippet within your app-level build.gradle :

compileOptions {

    sourceCompatibility JavaVersion.VERSION_1_7
    targetCompatibility JavaVersion.VERSION_1_7

}

Bootstrap 4 files do not come with the glyphicon support. But you can simply open up your bootstrap.css or bootstrap.min.css and paste this code which I came across here.

Try:

SELECT COALESCE(NULLIF(field, ''), another_field) FROM table_name

When you say:

c is not None

You are actually checking if c and None reference the same object. That is what the "is" operator does. In python None is a special null value conventionally meaning you don't have a value available. Sorta like null in c or java. Since python internally only assigns one None value using the "is" operator to check if something is None (think null) works, and it has become the popular style. However this does not have to do with the truth value of the set c, it is checking that c actually is a set rather than a null value.

If you want to check if a set is empty in a conditional statement, it is cast as a boolean in context so you can just say:

c = set()
if c:
   print "it has stuff in it"
else:
   print "it is empty"

But if you want it converted to a boolean to be stored away you can simply say:

c = set()
c_has_stuff_in_it = bool(c)

You can use -b to specify a cookie file to read the cookies from as well.

In many situations using -c and -b to the same file is what you want:

curl -b cookies.txt -c cookies.txt http://example.com

Further

Using only -c will make curl start with no cookies but still parse and understand cookies and if redirects or multiple URLs are used, it will then use the received cookies within the single invoke before it writes them all to the output file in the end.

The -b option feeds a set of initial cookies into curl so that it knows about them at start, and it activates curl's cookie parser so that it'll parse and use incoming cookies as well.

See Also

The cookies chapter in the Everything curl book.

For command line heads you can also run

sudo ln -s "/Applications/Visual Studio Code.app/Contents/Resources/app/bin/code" /usr/local/bin/code

this will do the exact same thing as the Shell Command: Install 'code' command in PATH command feature in VSCode.

None of the solutions listed above worked for me. I then decided to look at the actual function and realised that when “$scope.watch ” was fired, it was putting a value in the name field which was not meant to be the case. So in the code I set and oldValue and newValue then

$scope.$watch('model.value', function(newValue, oldValue) {
if (newValue !== oldValue) {
validateValue(newValue);
}
});

Essentially when scope.watch is fired in this case, AngularJS monitors the changes to the name variable (model.value)

You can' just add a class to each of your DIVs and apply the rule to the class in this way:

HTML:

<div class="myclass" id="s1">...</div>
<div class="myclass" id="s2">...</div>

CSS:

//css
.myclass
{
   ...
}

The only standard field Error object has is the message property. (See MDN, or EcmaScript Language Specification, section 15.11) Everything else is platform specific.

Mosts environments set the stack property, but fileName and lineNumber are practically useless to be used in inheritance.

So, the minimalistic approach is:

function MyError(message) {
    this.name = 'MyError';
    this.message = message;
    this.stack = (new Error()).stack;
}
MyError.prototype = new Error;  // <-- remove this if you do not 
                                //     want MyError to be instanceof Error

You could sniff the stack, unshift unwanted elements from it and extract information like fileName and lineNumber, but doing so requires information about the platform JavaScript is currently running upon. Most cases that is unnecessary -- and you can do it in post-mortem if you really want.

Safari is a notable exception. There is no stack property, but the throw keyword sets sourceURL and line properties of the object that is being thrown. Those things are guaranteed to be correct.

Test cases I used can be found here: JavaScript self-made Error object comparison.

I think that once you've imported it, the behaviour is the same (in the place your variable will be used outside source file).

The only difference would be if you try to reassign it before the end of this very file.

This is a very round-about way of doing it but if you want to make a histogram where you already know the bin values but dont have the source data, you can use the np.random.randint function to generate the correct number of values within the range of each bin for the hist function to graph, for example:

import numpy as np
import matplotlib.pyplot as plt

data = [np.random.randint(0, 9, *desired y value*), np.random.randint(10, 19, *desired y value*), etc..]
plt.hist(data, histtype='stepfilled', bins=[0, 10, etc..])

as for labels you can align x ticks with bins to get something like this:

#The following will align labels to the center of each bar with bin intervals of 10
plt.xticks([5, 15, etc.. ], ['Label 1', 'Label 2', etc.. ])

Use some javascript!

xmlhttp=new XMLHttpRequest();
xmlhttp.open('PUT',http://www.mydomain.org/documents/standards/browsers/supportlist)
xmlhttp.send("page content goes here");

StringUtils is an Apache Commons project. You need to download and add the library to your classpath.

To use:

import org.apache.commons.lang3.StringUtils;

Thanks yckart! Great contribution. I fleshed out your plugin a bit more. Added startAngle for full control and cross-browser css.

$.fn.animateRotate = function(startAngle, endAngle, duration, easing, complete){
    return this.each(function(){
        var elem = $(this);

        $({deg: startAngle}).animate({deg: endAngle}, {
            duration: duration,
            easing: easing,
            step: function(now){
                elem.css({
                  '-moz-transform':'rotate('+now+'deg)',
                  '-webkit-transform':'rotate('+now+'deg)',
                  '-o-transform':'rotate('+now+'deg)',
                  '-ms-transform':'rotate('+now+'deg)',
                  'transform':'rotate('+now+'deg)'
                });
            },
            complete: complete || $.noop
        });
    });
};

I use File -> Switch Workspace -> Other... and type in my new workspace name.

(EDIT: Added the composite screen shot.)

Once in the new workspace, File -> Import... and under General choose "Existing Projects into Workspace. Press the Next button and then Browse for the old projects you would like to import. Check "Copy projects into workspace" to make a copy.

Just do:

0 */2 * * *  /home/username/test.sh 

The 0 at the beginning means to run at the 0th minute. (If it were an *, the script would run every minute during every second hour.)

Don't forget, you can check syslog to see if it ever actually ran!

I hope I am not overstating the obvious, but why not do it directly in the ASP side? Unless you are dynamically altering the SQL based on certain conditions in your program, you should avoid codebehind as much as possible.

You could do the above all in ASP directly without code using the SqlDataSource control and a property in your dropdownlist.

<asp:GridView ID="gvSubjects" runat="server" DataKeyNames="SubjectID" OnRowDataBound="GridView_RowDataBound" OnDataBound="GridView_DataBound">
    <Columns>
        <asp:TemplateField HeaderText="Subjects">
            <ItemTemplate>
                <asp:DropDownList ID="ddlSubjects" runat="server" DataSourceID="sdsSubjects" DataTextField="SubjectName" DataValueField="SubjectID">
                </asp:DropDownList>
                <asp:SqlDataSource ID="sdsSubjects" runat="server"
                    SelectCommand="SELECT SubjectID,SubjectName FROM Students.dbo.Subjects"></asp:SqlDataSource>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

You do not need to calculate tree depths on the fly.

You can maintain them as you perform operations.

Furthermore, you don't actually in fact have to maintain track of depths; you can simply keep track of the difference between the left and right tree depths.

http://www.eternallyconfuzzled.com/tuts/datastructures/jsw_tut_avl.aspx

Just keeping track of the balance factor (difference between left and right subtrees) is I found easier from a programming POV, except that sorting out the balance factor after a rotation is a PITA...

Your code works fine, except that the barplot is ordered from low to high. When you want to order the bars from high to low, you will have to add a -sign before value:

ggplot(corr.m, aes(x = reorder(miRNA, -value), y = value, fill = variable)) + 
  geom_bar(stat = "identity")

which gives:

Used data:

corr.m <- structure(list(miRNA = structure(c(5L, 2L, 3L, 6L, 1L, 4L), .Label = c("mmu-miR-139-5p", "mmu-miR-1983", "mmu-miR-301a-3p", "mmu-miR-5097", "mmu-miR-532-3p", "mmu-miR-96-5p"), class = "factor"),
                         variable = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = "pos", class = "factor"),
                         value = c(7L, 75L, 70L, 5L, 10L, 47L)),
                    class = "data.frame", row.names = c("1", "2", "3", "4", "5", "6"))

A little more readable :)

public static <T> ArrayList<T> reverse(ArrayList<T> list) {
    int length = list.size();
    ArrayList<T> result = new ArrayList<T>(length);

    for (int i = length - 1; i >= 0; i--) {
        result.add(list.get(i));
    }

    return result;
}

We can use Angular event bindings to respond to any DOM event. The syntax is simple. We surround the DOM event name in parentheses and assign a quoted template statement to it. -- reference

Since change is on the list of standard DOM events, we can use it:

(change)="saverange()"

In your particular case, since you're using NgModel, you could break up the two-way binding like this instead:

[ngModel]="range" (ngModelChange)="saverange($event)"

Then

saverange(newValue) {
  this.range = newValue;
  this.Platform.ready().then(() => {
     this.rootRef.child("users").child(this.UserID).child('range').set(this.range)
  })
} 

However, with this approach saverange() is called with every keystroke, so you're probably better off using (change).

This technique is usually used for multiple axis in a figure. In this context it is often required to have a colorbar that corresponds in size with the result from imshow. This can be achieved easily with the axes grid tool kit:

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable

data = np.arange(100, 0, -1).reshape(10, 10)

fig, ax = plt.subplots()
divider = make_axes_locatable(ax)
cax = divider.append_axes('right', size='5%', pad=0.05)

im = ax.imshow(data, cmap='bone')

fig.colorbar(im, cax=cax, orientation='vertical')
plt.show()

Warning: Note that English is not restricted to just A-Z.

Try this to remove everything except a-z, A-Z and 0-9:

$result = preg_replace("/[^a-zA-Z0-9]+/", "", $s);

If your definition of alphanumeric includes letters in foreign languages and obsolete scripts then you will need to use the Unicode character classes.

Try this to leave only A-Z:

$result = preg_replace("/[^A-Z]+/", "", $s);

The reason for the warning is that words like résumé contains the letter é that won't be matched by this. If you want to match a specific list of letters adjust the regular expression to include those letters. If you want to match all letters, use the appropriate character classes as mentioned in the comments.

I was also stuck in similar kind of situation, setLevel() method was not coming, when I was trying to call it with the instance of HttpLoggingInterceptor, like this:

HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

Here is how I resolved it, to generate log for Retrofit2,

I suppose you have added the dependecy,

implementation "com.squareup.okhttp3:logging-interceptor:4.7.2"

For the latest version you can check out, this link:

https://github.com/square/okhttp/tree/master/okhttp-logging-interceptor )

Here they have also explained about how to add.

I created a class with name AddLoggingInterceptor, here is my code,

public class AddLoggingInterceptor {

    public static OkHttpClient setLogging(){
        HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
        loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

        OkHttpClient okHttpClient = new OkHttpClient.Builder()
                .addInterceptor(loggingInterceptor)
                .build();

        return okHttpClient;
    }
}

Then, where we are instantiating our Retrofit,

 public static Retrofit getRetrofitInstance() {
    if (retrofit == null) {
        retrofit = new retrofit2.Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .client(AddLoggingInterceptor.setLogging()) // here the method is called inside client() method, with the name of class, since it is a static method.
                .build();
    }
    return retrofit;
}

Now you can see log generated in your Android Studio, you may need to search, okHttp for filtering process. It worked for me. If any issues you can text me here.

You could make it absolute and put zeros to top and bottom that is:

#fullHeightDiv {
    position: absolute;
    top: 0;
    bottom: 0;
}

You should not set ENV variables in package.json. actionhero uses NODE_ENV to allow you to change configuration options which are loaded from the files in ./config. Check out the redis config file, and see how NODE_ENV is uses to change database options in NODE_ENV=test

If you want to use other ENV variables to set things (perhaps the HTTP port), you still don't need to change anything in package.json. For example, if you set PORT=1234 in ENV and want to use that as the HTTP port in NODE_ENV=production, just reference that in the relevant config file, IE:

# in config/servers/web.js
exports.production = { 
  servers: {
    web: function(api){
      return {
       port: process.env.PORT
      }
    }
  }
}

Add a build task to concatenate and register your html partials in the Angular $templateCache. (This answer is a more detailed variant of karlgold's answer.)

For grunt, use grunt-angular-templates. For gulp, use gulp-angular-templatecache.

Below are config/code snippets to illustrate.

gruntfile.js Example:

ngtemplates: {
  app: {                
    src: ['app/partials/**.html', 'app/views/**.html'],
    dest: 'app/scripts/templates.js'
  },
  options: {
    module: 'myModule'
  }
}

gulpfile.js Example:

var templateCache = require('gulp-angular-templatecache');
var paths = ['app/partials/.html', 'app/views/.html'];

gulp.task('createTemplateCache', function () {
return gulp.src(paths)
    .pipe(templateCache('templates.js', { module: 'myModule', root:'app/views'}))
    .pipe(gulp.dest('app/scripts'));
    });

templates.js (this file is autogenerated by the build task)

$templateCache.put('app/views/main.html', "<div class=\"main\">\r"...

index.html

<script src="app/scripts/templates.js"></script>
<div ng-include ng-controller="main as vm" src="'app/views/main.html'"></div>

1. first close the solution.
2. then solution cache file delete( in location C:\Users\Documents\Visual Studio\Backup Files/project cache file)
3. then .suo file delete
4. then solution open and build.

I hope solve your problem

Maybe these steps are not quite correct, but I do like this:

stop docker compose: $ docker-compose down

remove the container: $ docker system prune -a

start docker compose: $ docker-compose up -d

The getElementById method returns an Element object that you can use to interact with the element. If the element is not found, null is returned. In case of an input element, the value property of the object contains the string in the value attribute.

By using the fact that the && operator short circuits, and that both null and the empty string are considered "falsey" in a boolean context, we can combine the checks for element existence and presence of value data as follows:

var myInput = document.getElementById("customx");
if (myInput && myInput.value) {
  alert("My input has a value!");
}

You need to try one of the following:

1. GridBagLayout
2. MigLayout
3. SpringLayout

They offer many more features and will be easier to get what you are looking for.

If you don't like extra null checks:

if (Boolean.TRUE.equals(value)) {...}

try

<input type="text" class="normal" 
       style="text-transform:uppercase" 
       name="Name" size="20" maxlength="20"> 
 <img src="../images/tickmark.gif" border="0"/>

Instead of image put style tag on input because you are writing on input not on image

Expanding slightly on @Assaf answer, to apply formatting correctly I also had to convert the DateTime via the .ToOADate() function before the formatting took effect. You can do this on a cell by cell basis:

xlWorkSheet.Cells[Row, Col].NumberFormat = "<Required Format>"; // e.g. dd-MMM-yyyy
xlWorkSheet.Cells[Row, Col] = DateTimeObject.ToOADate();

Or you can apply the formatting to the entire column:

xlWorkSheet.Cells[Row, Col].EntireColumn.NumberFormat = "<Required Format>"; // e.g. dd-MMM-yyyy
xlWorkSheet.Cells[Row, Col] = DateTimeObject.ToOADate();

You Could try the other format for the case statement

CASE WHEN Product.type_id = 10
THEN
(
  Select Statement
)
ELSE
(
  Other select statement

)  
END
FROM Product 
WHERE Product.product_id = $pid

See http://msdn.microsoft.com/en-us/library/ms181765.aspx for more information.

I have these settings:

-vmargs
...
-Duser.name=...
-XX:PermSize=256m
-XX:MaxPermSize=256m
-Xmn128m
-Xms256m
-Xmx768m

Eclipse randomly crashed before I set the PermSize equal to MaxPermSize.

Vanilla JS

document.getElementById("textareaID").value

jQuery

$("#textareaID").val()

Cannot do the other way round (it's always good to know what you're doing)

document.getElementById("textareaID").value() // --> TypeError: Property 'value' of object #<HTMLTextAreaElement> is not a function

jQuery:

$("#textareaID").value // --> undefined

NOTE: this topic is about installation issues with MS project templates.

I came here via a search in Google, I was looking for a missing Template option in Visual Studio 2017 File menu: in VS-2015, it was Export to Template and I used it to add my own standard Project Items.

Meanwhile, I found an answer.. my issue was not related to default templates and it does not need install things. The option Export to Template has been moved to the VS-2017 Project menu !

You have written like

@Html.RadioButtonFor(model => model.gender, "Male", new { @checked = true }) and
@Html.RadioButtonFor(model => model.gender, "Female", new { @checked = true })

Here you have taken gender as a Enum type and you have written the value for the radio button as a string type- change "Male" to 0 and "Female" to 1.

Use subscripting to access the value for a dictionary key. This will return an Optional:

let apple: String? = companies["AAPL"]

or

if let apple = companies["AAPL"] {
    // ...
}

You can also enumerate over all of the keys and values:

var companies = ["AAPL" : "Apple Inc", "GOOG" : "Google Inc", "AMZN" : "Amazon.com, Inc", "FB" : "Facebook Inc"]

for (key, value) in companies {
    print("\(key) -> \(value)")
}

Or enumerate over all of the values:

for value in Array(companies.values) {
    print("\(value)")
}

Import the file into Excel by first opening excel, then going to DATA, import from TXT File, choose the csv extension which will preserve 0 prefixed values, and save that column as TEXT because excel will drop the leading 0 otherwise (DO NOT double click to open with Excel if you have numeric data in a field starting with a 0 [zero]). Then just save out as a Tab Delimited Text file. When you are importing into excel you get an option to save as GENERAL, TEXT, etc.. choose TEXT so that quotes in the middle of a string in a field like YourCompany,LLC are preserved also...

BULK INSERT dbo.YourTableName
FROM 'C:\Users\Steve\Downloads\yourfiletoIMPORT.txt'
WITH (
FirstRow = 2, (if skipping a header row)
FIELDTERMINATOR = '\t',
ROWTERMINATOR   = '\n'
)

I wish I could use the FORMAT and Fieldquote functionality but that does not appear to be supported in my version of SSMS

//gradle.properties

systemProp.http.proxyPassword=password

systemProp.http.nonProxyHosts=*.nonproxyrepos.com|localhost

nib is fine. If in doubt, refer to the Python style guide.

From PEP 8:

Package and Module Names Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability. Python packages should also have short, all-lowercase names, although the use of underscores is discouraged.

Since module names are mapped to file names, and some file systems are case insensitive and truncate long names, it is important that module names be chosen to be fairly short -- this won't be a problem on Unix, but it may be a problem when the code is transported to older Mac or Windows versions, or DOS.

When an extension module written in C or C++ has an accompanying Python module that provides a higher level (e.g. more object oriented) interface, the C/C++ module has a leading underscore (e.g. _socket).

You can use http://www.fontsquirrel.com/fontface/generator to encode any font for websites. It'll generate the code to include the font.

I don't really use it for fonts over 30px. They look much better as an image (because images are anti-aliased, and some browsers don't anti-alias fonts in the browser).

See: http://www.truetype-typography.com/ttalias.htm

Hope that helps...

Although this question is very old, but I see still there are no exact answer. I will try to answer the question here.

I believe the question in short here is how to set the proxy settings for the Apache commons HttpClient (org.apache.commons.httpclient.HttpClient).

Code snippet below should work :

HttpClient client = new HttpClient();
HostConfiguration hostConfiguration = client.getHostConfiguration();
hostConfiguration.setProxy("localhost", 8080);
client.setHostConfiguration(hostConfiguration);

if you have already pushed your commit then. do

git checkout origin/<remote-branch> <filename>
git commit --amend

AND If you have not pushed the changes on the server you can use

git reset --soft HEAD~1

Edit: Solution for L5.2+

There's a better and more straightforward solution.

Use Storage::url($filename) to get the full path/URL of a given file. Note that you need to set S3 as your storage filesystem in config/filesystems.php: 'default' => 's3'

Of course, you can also do Storage::disk('s3')->url($filename) in the same way.

As you can see in config/filesystems.php there's also a parameter 'cloud' => 's3' defined, that refers to the Cloud filesystem. In case you want to mantain the storage folder in the local server but retrieve/store some files in the cloud use Storage::cloud(), which also has the same filesystem methods, i.e. Storage::cloud()->url($filename).

The Laravel documentation doesn't mention this method, but if you want to know more about it you can check its source code here.

The easiest way I can think of is to use Linq:

List<Order> SortedList = objListOrder.OrderBy(o=>o.OrderDate).ToList();

How do we retrieve a value from a text field?

mytestField.getText();

ActionListner example:

mytextField.addActionListener(this);

public void actionPerformed(ActionEvent evt) {
    String text = textField.getText();
    textArea.append(text + newline);
    textField.selectAll();
}

function getValue(){
    for(var i = 0 ; i< array.length; i++){
        var obj = array[i];
        var arr = array["types"];
        for(var j = 0; j<arr.length;j++ ){
            if(arr[j] == "value"){
                return obj;
            }
        }

    }
}

Most of answers do not get the point.

There is ONE reason matlab is so good and so widely used:

EXTREMELY FAST CODING

I am a computer vision phD student and have been using matlab for 4 years, before my phD I was using different languages including C++, java, php, python... Most of the computer vision researchers are using exclusively matlab.

1) Researchers need fast prototyping

In research environment, we have (hopefully) often new ideas, and we want to test them really quick to see if it's worth keeping on in that direction. And most often only a tiny sub-part of what we code will be useful.

Matlab is often slower at execution time, but we don't care much. Because we don't know in advance what method is going to be successful, we have to try many things, so our bottle neck is programming time, because our code will most often run a few times to get the results to publish, and that's all.

So let's see how matlab can help.

2) Everything I need is already there

Matlab has really a lot of functions that I need, so that I don't have to reinvent them all the time:

change the index of a matrix to 2d coordinate: ind2sub extract all patches of an image: im2col; compute a histogram of an image: hist(Im(:)); find the unique elements in a list unique(list); add a vector to all vectors of a matrix bsxfun(@plus,M,V); convolution on n-dimensional arrays convn(A); calculate the computation time of a sub part of the code: tic; %%code; toc; graphical interface to crop an image: imcrop(im);

The list could be very long... And they are very easy to find by using the help.

The closest to that is python...But It's just a pain in python, I have to go to google each time to look for the name of the function I need, and then I need to add packages, and the packages are not compatible one with another, the format of the matrix change, the convolution function only handle doubles but does not make an error when I give it char, just give a wrong output... no

3) IDE

An example: I launch a script. It produces an error because of a matrix. I can still execute code with the command line. I visualize it doing: imagesc(matrix). I see that the last line of the matrix is weird. I fix the bug. All variables are still set. I select the remaining of the code, press F9 to execute the selection, and everything goes on. Debuging becomes fast, thanks to that.

Matlab underlines some of my errors before execution. So I can quickly see the problems. It proposes some way to make my code faster.

There is an awesome profiler included in the IDE. KCahcegrind is such a pain to use compared to that.

python's IDEs are awefull. python without ipython is not usable. I never manage to debug, using ipython.

+autocompletion, help for function arguments,...

4) Concise code

To normalize all the columns of a matrix ( which I need all the time), I do: bsxfun(@times,A,1./sqrt(sum(A.^2)))

To remove from a matrix all colums with small sum:

A(:,sum(A)<e)=[]

To do the computation on the GPU:

gpuX = gpuarray(X); 
%%% code normally and everything is done on GPU

To paralize my code:

parfor n=1:100
%%% code normally and everything is multi-threaded

What language can beat that?

And of course, I rarely need to make loops, everything is included in functions, which make the code way easier to read, and no headache with indices. So I can focus, on what I want to program, not how to program it.

5) Plotting tools

Matlab is famous for its plotting tools. They are very helpful.

Python's plotting tools have much less features. But there is one thing super annoying. You can plot figures only once per script??? if I have along script I cannot display stuffs at each step ---> useless.

6) Documentation

Everything is very quick to access, everything is crystal clear, function names are well chosen. With python, I always need to google stuff, look in forums or stackoverflow.... complete time hog.

PS: Finally, what I hate with matlab: its price

You can supply your own class to the nav-pills container with your custom color for your active link, that way you can create as many colors as you like without modifying the bootstrap default colors in other sections of your page. Try this:

Markup

<ul class="nav nav-pills red">
    <li class="active"><a href="#tab1" data-toggle="tab">Overview</a></li>
    <li><a href="#tab2" data-toggle="tab">Sample</a></li>
    <li><a href="#tab3" data-toggle="tab">Sample</a></li>
</ul>

And here is the CSS for your custom color:

.red .active a,
.red .active a:hover {
    background-color: red;
}

Also, if you prefer to replace the default color for the .active item in your nav-pills you can modify the original like so:

.nav-pills > .active > a, .nav-pills > .active > a:hover {
    background-color: red;
}

I resolved this issue by creating a file called .user.ini in the directory where the PHP file scripts reside (this means any PHP script in this directory gets the new file size limit)

The contents of .user.ini were:

upload_max_filesize = 40M
post_max_size = 40M

Much easier way in PowerShell:

Get-ADPrincipalGroupMembership <username>

Requirement: the account you yourself are running under must be a member of the same domain as the target user, unless you specify -Credential and -Server (untested).

In addition, you must have the Active Directory Powershell module installed, which as @dave-lucre says in a comment to another answer, is not always an option.

For group names only, try one of these:

(Get-ADPrincipalGroupMembership <username>).Name
Get-ADPrincipalGroupMembership <username> |Select Name

The shorthand is:

$(function() {
    // Code here
});

You are using the wrong build.gradle file.

In your top-level file you can't define an android block.

Just move this part inside the module/build.gradle file.

android {
    compileSdkVersion 17
    buildToolsVersion '23.0.0'
}
dependencies {
    compile files('app/libs/junit-4.12-JavaDoc.jar')
}
apply plugin: 'maven'

I Just came across to a similar to this question solution with included some performance statistics.

It seems that example below is faster:

document.getElementById('container').insertAdjacentHTML('beforeend', '<div id="idChild"> content html </div>');

InnerHTML vs jQuery 1 vs appendChild vs innerAdjecentHTML.

Reference: 1) Performance stats 2) API - insertAdjacentHTML

I hope this will help.

Sounds like you're trying to avoid passing a reference to this into the method. Passing this is way better than finding the caller through the current stack trace. Refactoring to a more OO design is even better. You shouldn't need to know the caller. Pass a callback object if necessary.

This should do the trick:

<table width="400" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td width="50" height="40" valign="top" rowspan="3">
      <img alt="" src="" width="40" height="40" style="margin: 0; border: 0; padding: 0; display: block;">
    </td>
    <td width="350" height="40" style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; color: #000000;">
<a href="" style="color: #D31145; font-weight: bold; text-decoration: none;">LAST FIRST</a><br>

    </td>
  </tr>

UPDATE: Adjusted code per the comments:

After viewing your jsFiddle, an important thing to note about tables is that table cell widths in each additional row all have to be the same width as the first, and all cells must add to the total width of your table.

Here is an example that will NOT WORK:

<table width="600" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td width="200" bgcolor="#252525">&nbsp;
    </td>
    <td width="400" bgcolor="#454545">&nbsp;
    </td>
  </tr>
  <tr>
    <td width="300" bgcolor="#252525">&nbsp;
    </td>
    <td width="300" bgcolor="#454545">&nbsp;
    </td>
  </tr>
</table>

Although the 2nd row does add up to 600, it (and any additional rows) must have the same 200-400 split as the first row, unless you are using colspans. If you use a colspan, you could have one row, but it needs to have the same width as the cells it is spanning, so this works:

<table width="600" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td width="200" bgcolor="#252525">&nbsp;
    </td>
    <td width="400" bgcolor="#454545">&nbsp;
    </td>
  </tr>
  <tr>
    <td width="600" colspan="2" bgcolor="#353535">&nbsp;
    </td>
  </tr>
</table>

Not a full tutorial, but I hope that helps steer you in the right direction in the future.

Here is the code you are after:

<table width="900" border="0" cellpadding="0" cellspacing="0">
  <tr>
    <td width="57" height="43" valign="top" rowspan="2">
      <img alt="Rashel Adragna" src="http://zoparealtygroup.com/wp-content/uploads/2013/10/sig_head.png" width="47" height="43" style="margin: 0; border: 0; padding: 0; display: block;">
    </td>
    <td width="843" height="43" style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; color: #000000;">
<a href="" style="color: #D31145; font-weight: bold; text-decoration: none;">RASHEL ADRAGNA</a><br>
REALTOR | P 855.900.24KW
    </td>
  </tr>
  <tr>
    <td width="843" height="64" valign="bottom" style="font-family: Helvetica, Arial, sans-serif; font-size: 14px; color: #000000;">
<img alt="Zopa Realty Group logo" src="http://zoparealtygroup.com/wp-content/uploads/2013/10/sig_logo.png" width="177" height="54" style="margin: 0; border: 0; padding: 0; display: block;">
    </td>
  </tr>
  <tr>
    <td width="843" colspan="2" height="20" valign="bottom" align="center" style="font-family: Helvetica, Arial, sans-serif; font-size: 10px; color: #000000;">
all your minor text here | all your minor text here | all your minor text here
    </td>
  </tr>
</table>

You'll note that I've added an extra 10px to some of your table cells. This in combination with align/valigns act as padding between your cells. It is a clever way to aviod actually having to add padding, margins or empty padding cells.

In my opinion the best tool for such testing is curl. Its --upload-file option uploads a file by PUT, which is exactly what you want (and it can do much more, like modifying HTTP headers, in case you need it):

curl http://myservice --upload-file file.txt

A side note: Windows users should run os.system('color') first, otherwise you would see some ANSI escape sequences rather than a colored output.

I got frustrated too. My need was very straightforward. All I wanted was the ARGB color from the resources, so I wrote a simple static method.

protected static int getARGBColor(Context c, int resId)
        throws Resources.NotFoundException {

    TypedValue color = new TypedValue();
    try {
        c.getResources().getValue(resId, color, true);
    }
    catch (Resources.NotFoundException e) {
        throw(new Resources.NotFoundException(
                  String.format("Failed to find color for resourse id 0x%08x",
                                resId)));
    }
    if (color.type != TYPE_INT_COLOR_ARGB8) {
        throw(new Resources.NotFoundException(
                  String.format(
                      "Resourse id 0x%08x is of type 0x%02d. Expected TYPE_INT_COLOR_ARGB8",
                      resId, color.type))
        );
    }
    return color.data;
}

Using the ArrayObject from Std or building your own

(new \ArrayObject($existingStdClass))

you can use the build in method on the new class:

getArrayCopy()

or pass the new object to

iterator_to_array

You can use jquery function.

<form name='add'>
   <input type='text' name='stud_name' id="stud_name" value=""/>
   Age: <select name='age' id="age">
   <option value='1' stud_name='sre'>23</option>
   <option value='2' stud_name='sam'>24</option>
   <option value='5' stud_name='john'>25</option>
   </select>
   <input type='submit' name='submit'/>
</form>

jquery code :

<script type="text/javascript" src="jquery.js"></script>

<script>
    $(function() {
          $("#age").change(function(){
          var option = $('option:selected', this).attr('stud_name');
          $('#stud_name').val(option);
       });
    });
</script>

Extension with optional locale

Swift 2.2

extension String {
    func toDouble(locale: NSLocale? = nil) -> Double? {
        let formatter = NSNumberFormatter()
        if let locale = locale {
            formatter.locale = locale
        }
        return formatter.numberFromString(self)?.doubleValue
    }
}

Swift 3.1

extension String {
    func toDouble(_ locale: Locale) -> Double {
        let formatter = NumberFormatter()
        formatter.numberStyle = .decimal
        formatter.locale = locale
        formatter.usesGroupingSeparator = true
        if let result = formatter.number(from: self)?.doubleValue {
            return result
        } else {
            return 0
        }
    }
}

As mentioned by MatBailie This is much more safe since it is not a dynamic query and ther are lesser chances of sql injection . I Added one situation where you even want the where clause to be dynamic . XX YY are Columns names

            CREATE PROCEDURE [dbo].[DASH_getTP_under_TP]
    (
    @fromColumnName varchar(10) ,
    @toColumnName varchar(10) , 
    @ID varchar(10)
    )
    as
    begin

    -- this is the column required for where clause 
    declare @colname varchar(50)
    set @colname=case @fromUserType
        when 'XX' then 'XX'
        when 'YY' then 'YY'
        end
        select SelectedColumnId  from (
       select 
            case @toColumnName 
            when 'XX' then tablename.XX
            when 'YY' then tablename.YY
            end as SelectedColumnId,
        From tablename
        where 
        (case @fromUserType 
            when 'XX' then XX
            when 'YY' then YY
        end)= ISNULL(@ID , @colname) 
    ) as tbl1 group by SelectedColumnId 

    end

My preferred method is this:

NSString *firstString = @"foo";
NSString *secondString = @"bar";
NSString *thirdString = @"baz";

NSString *joinedString = [@[firstString, secondString, thirdString] join];

You can achieve it by adding the join method to NSArray with a category:

#import "NSArray+Join.h"
@implementation NSArray (Join)
-(NSString *)join
{
    return [self componentsJoinedByString:@""];
}
@end

@[] it's the short definition for NSArray, I think this is the fastest method to concatenate strings.

If you don't want to use the category, use directly the componentsJoinedByString: method:

NSString *joinedString = [@[firstString, secondString, thirdString] componentsJoinedByString:@""];

Use DateFormat. (Sorry, but the brevity of the question does not warrant a longer or more detailed answer.)

It is possible to get both the primary and secondary axes on one side of the chart by designating the secondary axis for one of the series.

To get the primary axis on the right side with the secondary axis, you need to set to "High" the Axis Labels option in the Format Axis dialog box for the primary axis.

To get the secondary axis on the left side with the primary axis, you need to set to "Low" the Axis Labels option in the Format Axis dialog box for the secondary axis.

I know of no way to get a third set of axis labels on a single chart. You could fake in axis labels & ticks with text boxes and lines, but it would be hard to get everything aligned correctly.

The more feasible route is that suggested by zx8754: Create a second chart, turning off titles, left axes, etc. and lay it over the first chart. See my very crude mockup which hasn't been fine-tuned yet.

Use EchoX.EXE from the terrific "Shell Scripting Toolkit" by Bill Stewart
How to suppress the linefeed in a Windows Cmd script:

@Echo Off
Rem Print three Echos in one line of output
EchoX -n "Part 1 - "
EchoX -n "Part 2 - "
EchoX    "Part 3"
Rem

gives:

Part 1 - Part 2 - Part 3
{empty line}
d:\Prompt>

The help for this usage is:

Usage: echox [-n] message
  -n       Do not skip to the next line.
  message  The text to be displayed.

The utility is smaller than 48K, and should live in your Path. More things it can do:
- print text without moving to the next line
- print text justified to the left, center, or right, within a certain width
- print text with Tabs, Linefeeds, and Returns
- print text in foreground and background colors

The Toolkit includes twelve more great scripting tricks.
The download page also hosts three other useful tool packages.

From this wikipedia entry:

The JDK is a subset of what is loosely defined as a software development kit (SDK) in the general sense. In the descriptions which accompany their recent releases for Java SE, EE, and ME, Sun acknowledge that under their terminology, the JDK forms the subset of the SDK which is responsible for the writing and running of Java programs. The remainder of the SDK is composed of extra software, such as Application Servers, Debuggers, and Documentation.

The "extra software" seems to be Glassfish, MySQL, and NetBeans. This page gives a comparison of the various packages you can get for the Java EE SDK.

The use of the deprecated new Buffer() constructor (i.E. as used by Yarn) can cause deprecation warnings. Therefore one should NOT use the deprecated/unsafe Buffer constructor.

According to the deprecation warning new Buffer() should be replaced with one of:

• Buffer.alloc()
• Buffer.allocUnsafe() or
• Buffer.from()

Another option in order to avoid this issue would be using the safe-buffer package instead.

You can also try (when using yarn..):

yarn global add yarn

as mentioned here: Link

Another suggestion from the comments (thx to gkiely): self-update

Note: self-update is not available. See policies for enforcing versions within a project

In order to update your version of Yarn, run

curl --compressed -o- -L https://yarnpkg.com/install.sh | bash

//step loop_x000D_
for(var i = 0; i < substr.length; i+=2) {_x000D_
  console.log("step", substr[i])_x000D_

for in

//dont really wnt to use this on arrays, use it on objects
for(var i in substr) {
    console.log(substr[i]) //note i returns index

Resources

MDN loops and iterators

This is slightly tricky as you have to know when the iframe page has loaded, which is difficuly when you're not in control of its content. Its possible to add an onload handler to the iframe, but I've tried this in the past and it has vastly different behaviour across browsers (not guess who's the most annoying...). You'd probably have to add a function to the iframe page that performs the resize and inject some script into the content that either listens to load events or resize events, which then calls the previous function. I'm thinking add a function to the page since you want to make sure its secure, but I have no idea how easy it will be to do.

In my use case, I wanted to asynchronously retrieve a url, and then follow that url to an external resource in a new window. A directive seemed overkill because I don't need reusability, so I simply did:

<button (click)="navigateToResource()">Navigate</button>

And in my component.ts

navigateToResource(): void {
  this.service.getUrl((result: any) => window.open(result.url));
}

Note:

Routing to a link indirectly like this will likely trigger the browser's popup blocker.

Try the following piece of code:

self.navigationController.navigationBar.translucent = YES;

In normal mode:

gg"+yG

In ex mode:

:%y+

Try using the data option of the $.ajax function. More info here.

$('#btnSaveComments').click(function () {
    var comments = $('#txtComments').val();
    var selectedId = $('#hdnSelectedId').val();

    $.ajax({
        url: '<%: Url.Action("SaveComments")%>',
        data: { 'id' : selectedId, 'comments' : comments },
        type: "post",
        cache: false,
        success: function (savingStatus) {
            $("#hdnOrigComments").val($('#txtComments').val());
            $('#lblCommentsNotification').text(savingStatus);
        },
        error: function (xhr, ajaxOptions, thrownError) {
            $('#lblCommentsNotification').text("Error encountered while saving the comments.");
        }
    });
});

        childProcess.stderr.on("data", function (data) {
            console.error(data.toString());
        });
    }
}

Example of use:

    Cli.execute(Grunt._command, args, function (command, args, env) {
        console.log('Grunt has been automatically executed. (' + env + ')');

    }, function (command, args, env) {
        console.error('------------- Windows "' + command + '" command failed, trying Unix... ---------------');

    }, function (command, args, env) {
        console.error('------------- Unix "' + command + '" command failed too. ---------------');
    });

I know this question was specific to JavaScript, however, there seems to be no good, clean way to ALWAYS detect when a textarea changes in all current browsers. I've learned jquery has taken care of it for us. It even handles contextual menu changes to text areas. The same syntax is used regardless of input type.

    $('div.lawyerList').on('change','textarea',function(){
      // Change occurred so count chars...
    });

or

    $('textarea').on('change',function(){
      // Change occurred so count chars...
    });

Please check in logs if you have http.HttpWagon$__sisu1:Cannot find 'basicAuthScope' this error or warning also, if so you need to use maven 3.2.5 version, which will resolve error.

Using the knitr package:

```{r, engine='bash', code_block_name} ...

E.g.:

```{r, engine='bash', count_lines}
wc -l en_US.twitter.txt
```

You can also use:

• engine='sh' for shell
• engine='python' for Python
• engine='perl', engine='haskell' and a bunch of other C-like languages and even gawk, AWK, etc.

Follow these steps:

1. Add the Action Bar instance in the Java Code final ActionBar actionBar = getActionBar();
2. Enable the Home Display Option actionBar.setDisplayShowHomeEnabled(false);
3. Add the following code in the respective activity's manifest file android:logo=@drawable/logo and android:label="@string/actionbar_text"

I think this will help you

A compact way to find multiple strings in another list of strings is to use set.intersection. This executes much faster than list comprehension in large sets or lists.

>>> astring = ['abc','def','ghi','jkl','mno']
>>> bstring = ['def', 'jkl']
>>> a_set = set(astring)  # convert list to set
>>> b_set = set(bstring)
>>> matches = a_set.intersection(b_set)
>>> matches
{'def', 'jkl'}
>>> list(matches) # if you want a list instead of a set
['def', 'jkl']
>>>

In short "How do I remove from a map while iterating it?"

• With old map impl: You can't
• With new map impl: almost as @KerrekSB suggested. But there are some syntax issues in what he posted.

Use the native function htmlspecialchars. It will escape from all special character. If you want to escape from a quote specifically, use with ENT_COMPAT or ENT_QUOTES. Here is the example:

$str = "Jane & 'Tarzan'";
echo htmlspecialchars($str, ENT_COMPAT); // Will only convert double quotes
echo "<br>";

echo htmlspecialchars($str, ENT_QUOTES); // Converts double and single quotes
echo "<br>";

echo htmlspecialchars($str, ENT_NOQUOTES); // Does not convert any quotes

The output would be like this:

Jane &amp; 'Tarzan'<br>
Jane &amp; &#039;Tarzan&#039;<br>
Jane &amp; 'Tarzan'

As well as making sure that you have first called $("#myForm").validate();, make sure that your dynamic control has been added to the DOM before adding the validation rules.

catch function in your api should either return some data which could be handled by Api call in React class or throw new error which should be caught using a catch function in your React class code. Latter approach should be something like:

return fetch(url)
.then(function(response){
  return response.json();
})
.then(function(json){
  return {
    city: json.name,
    temperature: kelvinToF(json.main.temp),
    description: _.capitalize(json.weather[0].description)
  }
})
.catch(function(error) {
console.log('There has been a problem with your fetch operation: ' + error.message);
 // ADD THIS THROW error
  throw error;
});

Then in your React Class:

Api(region.latitude, region.longitude)
  .then((data) => {
    console.log(data);
    this.setState(data);
  }).catch((error)=>{
     console.log("Api call error");
     alert(error.message);
  });

This will ensure you get a two-digit day and month.

function formattedDate(d = new Date) {
  let month = String(d.getMonth() + 1);
  let day = String(d.getDate());
  const year = String(d.getFullYear());

  if (month.length < 2) month = '0' + month;
  if (day.length < 2) day = '0' + day;

  return `${day}/${month}/${year}`;
}

Or terser:

function formattedDate(d = new Date) {
  return [d.getDate(), d.getMonth()+1, d.getFullYear()]
      .map(n => n < 10 ? `0${n}` : `${n}`).join('/');
}

Seems like a bug to me. I've had the same problem and worked around it by manually starting gradlew.bat in my project directory.

When you use a function ...

<p onclick="update_url('/en/step2');">Link</p>

<script>
function update_url(url) {
    history.pushState(null, null, url);
}
</script>

You can use JSON.stringify like:

JSON.stringify(new_tweets);

$post = Post::select(DB::raw('count(*) as user_count, category_id'))
              ->groupBy('category_id')
              ->get();

This is an example which results count of post by category.

I had a situation where I needed to compare each row of a table with the next row to it, (next here is relative to my problem specification) in the example next row is specified using the order by clause inside the row_number() function.

so I wrote this:

DECLARE @T TABLE (col1 nvarchar(50));

insert into @T VALUES ('A'),('B'),('C'),('D'),('E')

select I1.col1 Instance_One_Col, I2.col1 Instance_Two_Col  from (
 select col1,row_number() over (order by col1) as row_num
 FROM @T
) AS I1
left join (
 select col1,row_number() over (order by col1) as row_num
 FROM @T
) AS I2 on I1.row_num = I2.row_num - 1

after that I can compare each row to the next one as I need

graph-fs

Install

npm i graph-fs

Use

const {Node} = require("graph-fs");
const directory = new Node("/path/to/directory");

directory.clear(); // <--

a_list = []
b_list = []
for i in range(1,100):
    a_list.append(random.randint(1,100))

for i in range(1,100):
    a_list.append(random.randint(101,200))
[sum(x) for x in zip(a_list , b_list )]

What I found useful and I found on one link above is this FQL query where you ask for likes, total, share and click count of one link by looking at the link_stat table

https://graph.facebook.com/fql?q=SELECT%20like_count,%20total_count,%20share_count,%20click_count,%20comment_count%20FROM%20link_stat%20WHERE%20url%20=%20%22http://google.com%22

That will output something like this:

{
    data: [
        {
             like_count: 3440162,
             total_count: 13226503,
             share_count: 7732740,
             click_count: 265614,
             comment_count: 2053601
         }
    ]
}

Normally it happens when the target is null. So better check the invoke target first then do the linq query.

Here is a solution to your problem:

I've tried to solve problem like yours & I want to suggest to test from simple aspect.

Follow these steps: Learn from simple solution.

Step 1: Create a table schema using this SQL Query:

CREATE TABLE IF NOT EXISTS `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(30) NOT NULL,
  `password` varchar(32) NOT NULL,
  `status` tinyint(1) DEFAULT '0',
  PRIMARY KEY (`id`),
  UNIQUE KEY `no_duplicate` (`username`,`password`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1;

Step 2: Create an index of two columns to prevent duplicate data using following SQL Query:

ALTER TABLE `user` ADD INDEX no_duplicate (`username`, `password`);

or, Create an index of two column from GUI as follows:

Step 3: Update if exist, insert if not using following queries:

INSERT INTO `user`(`username`, `password`) VALUES ('ersks','Nepal') ON DUPLICATE KEY UPDATE `username`='master',`password`='Nepal';

INSERT INTO `user`(`username`, `password`) VALUES ('master','Nepal') ON DUPLICATE KEY UPDATE `username`='ersks',`password`='Nepal';

I came across same issue. I was getting error Unable to open debugger port (127.0.0.1:63936): java.net.BindException "Address already in use: JVM_Bind" I tried above all option but any how its not resolved. Solution which worked for me is, I started the server and then stopped and again started in debug mode. then the server got started in debug mode.

NetBeans update their tutorial for JDK8 and this Issue:

Getting Started with JAX-WS Web Services -> Enabling Access to External Schema

You need to get ObjectNode type object in order to set values. Take a look at this

This is how I did it

// sets Asia/Calcutta time zone
date_default_timezone_set("Asia/Calcutta");

//fetches current date and time
$date = date("Y-m-d H:i:s");

$dateArray = date_parse_from_format('Y/m/d', $date);
$month = DateTime::createFromFormat('!m', $dateArray['month'])->format('F');
$dateString = $dateArray['day'] . " " . $month  . " " . $dateArray['year'];

echo $dateString;

returns 30 June 2019

You can put a hack in your foreach, such as a field incremented on each run-through, which is exactly what the for loop gives you in a numerically-indexed array. Such a field would be a pseudo-index that needs manual management (increments, etc).

A foreach will give you your index in the form of your $key value, so such a hack shouldn't be necessary.

e.g., in a foreach

$index = 0;
foreach($data as $key=>$val) {
    // Use $key as an index, or...

    // ... manage the index this way..
    echo "Index is $index\n";
    $index++;
}

Go to Settings -> Style Configurator

Select Theme: Choose whichever you like best (the top two are easiest to read by most people's preference)

Unsure what dbms you're using however I'd do it this way in Microsoft SQL:

select      [date]
from        tbemp 
order by    cast([date] as datetime) asc

An alternative way of getting a feel of solutions provided by netters is to understand a little geometry implications.

Let pqr=[P,Q,R] are points that forms a plane that is divided into 2 sides by line [P,R]. We are to find out if two points on pqr plane, A,B, are on the same side.

Any point T on pqr plane can be represented with 2 vectors: v = P-Q and u = R-Q, as:

T' = T-Q = i * v + j * u

Now the geometry implications:

1. i+j =1: T on pr line
2. i+j <1: T on Sq
3. i+j >1: T on Snq
4. i+j =0: T = Q
5. i+j <0: T on Sq and beyond Q.

i+j: <0 0 <1 =1 >1 ---------Q------[PR]--------- <== this is PQR plane ^ pr line

In general,

• i+j is a measure of how far T is away from Q or line [P,R], and
• the sign of i+j-1 implicates T's sideness.

The other geometry significances of i and j (not related to this solution) are:

• i,j are the scalars for T in a new coordinate system where v,u are the new axes and Q is the new origin;
• i, j can be seen as pulling force for P,R, respectively. The larger i, the farther T is away from R (larger pull from P).

The value of i,j can be obtained by solving the equations:

i*vx + j*ux = T'x
i*vy + j*uy = T'y
i*vz + j*uz = T'z

So we are given 2 points, A,B on the plane:

A = a1 * v + a2 * u B = b1 * v + b2 * u

If A,B are on the same side, this will be true:

sign(a1+a2-1) = sign(b1+b2-1)

Note that this applies also to the question: Are A,B in the same side of plane [P,Q,R], in which:

T = i * P + j * Q + k * R

and i+j+k=1 implies that T is on the plane [P,Q,R] and the sign of i+j+k-1 implies its sideness. From this we have:

A = a1 * P + a2 * Q + a3 * R B = b1 * P + b2 * Q + b3 * R

and A,B are on the same side of plane [P,Q,R] if

sign(a1+a2+a3-1) = sign(b1+b2+b3-1)

I use this method to add a border outside the image. You can customise the border width in boderWidth constant.

Swift 3

func addBorderToImage(image : UIImage) -> UIImage {
    let bgImage = image.cgImage
    let initialWidth = (bgImage?.width)!
    let initialHeight = (bgImage?.height)!
    let borderWidth = Int(Double(initialWidth) * 0.10);
    let width = initialWidth + borderWidth * 2
    let height = initialHeight + borderWidth * 2
    let data = malloc(width * height * 4)

    let context = CGContext(data: data,
                        width: width,
                        height: height,
                        bitsPerComponent: 8,
                        bytesPerRow: width * 4,
                        space: (bgImage?.colorSpace)!,
                        bitmapInfo: CGImageAlphaInfo.premultipliedLast.rawValue);

    context?.draw(bgImage!, in: CGRect(x: CGFloat(borderWidth), y: CGFloat(borderWidth), width: CGFloat(initialWidth), height: CGFloat(initialHeight)))
    context?.setStrokeColor(UIColor.white.cgColor)
    context?.setLineWidth(CGFloat(borderWidth))
    context?.move(to: CGPoint(x: 0, y: 0))
    context?.addLine(to: CGPoint(x: 0, y: height))
    context?.addLine(to: CGPoint(x: width, y: height))
    context?.addLine(to: CGPoint(x: width, y: 0))
    context?.addLine(to: CGPoint(x: 0, y: 0))
    context?.strokePath()

    let cgImage = context?.makeImage()
    let uiImage = UIImage(cgImage: cgImage!)

    free(data)

    return uiImage;
}

Would something like this work better ?

public static void removeDuplicates(ArrayList<String> list) {
    Arraylist<Object> ar     = new Arraylist<Object>();
    Arraylist<Object> tempAR = new Arraylist<Object>();
    while (list.size()>0){
        ar.add(list(0));
        list.removeall(Collections.singleton(list(0)));
    }
    list.addAll(ar);
}

That should maintain the order and also not be quadratic in run time.

typeof(AbstractDataExport).Assembly tells you an assembly your types are located in (assuming all are in the same).

assembly.GetTypes() gives you all types in that assembly or assembly.GetExportedTypes() gives you types that are public.

Iterating through the types and using type.IsAssignableFrom() gives you whether the type is derived.

The answer by Stephen Katulka (accepted answer) is wrong (the second part). It explains that Collections.copy(b, a); does a deep copy, which it does not. Both, new ArrayList(a); and Collections.copy(b, a); only do a shallow copy. The difference is, that the constructor allocates new memory, and copy(...) does not, which makes it suitable in cases where you can reuse arrays, as it has a performance advantage there.

The Java standard API tries to discourage the use of deep copies, as it would be bad if new coders would use this on a regular basis, which may also be one of the reason why clone() is not public by default.

The source code for Collections.copy(...) can be seen on line 552 at: http://www.java2s.com/Open-Source/Java-Document/6.0-JDK-Core/Collections-Jar-Zip-Logging-regex/java/util/Collections.java.htm

If you need a deep copy, you have to iterate over the items manually, using a for loop and clone() on each object.

Well there are 2 methods:

Method 1: A well-known method for renaming database schema is by dumping the schema using Mysqldump and restoring it in another schema, and then dropping the old schema (if needed).

From Shell

 mysqldump emp > emp.out
 mysql -e "CREATE DATABASE employees;"
 mysql employees < emp.out 
 mysql -e "DROP DATABASE emp;"

Although the above method is easy, it is time and space consuming. What if the schema is more than a 100GB? There are methods where you can pipe the above commands together to save on space, however it will not save time.

To remedy such situations, there is another quick method to rename schemas, however, some care must be taken while doing it.

Method 2: MySQL has a very good feature for renaming tables that even works across different schemas. This rename operation is atomic and no one else can access the table while its being renamed. This takes a short time to complete since changing a table’s name or its schema is only a metadata change. Here is procedural approach at doing the rename:

Create the new database schema with the desired name. Rename the tables from old schema to new schema, using MySQL’s “RENAME TABLE” command. Drop the old database schema. If there are views, triggers, functions, stored procedures in the schema, those will need to be recreated too. MySQL’s “RENAME TABLE” fails if there are triggers exists on the tables. To remedy this we can do the following things :

1) Dump the triggers, events and stored routines in a separate file. This done using -E, -R flags (in addition to -t -d which dumps the triggers) to the mysqldump command. Once triggers are dumped, we will need to drop them from the schema, for RENAME TABLE command to work.

 $ mysqldump <old_schema_name> -d -t -R -E > stored_routines_triggers_events.out

2) Generate a list of only “BASE” tables. These can be found using a query on information_schema.TABLES table.

 mysql> select TABLE_NAME from information_schema.tables where 
    table_schema='<old_schema_name>' and TABLE_TYPE='BASE TABLE';

3) Dump the views in an out file. Views can be found using a query on the same information_schema.TABLES table.

mysql> select TABLE_NAME from information_schema.tables where 
   table_schema='<old_schema_name>' and TABLE_TYPE='VIEW';
 $ mysqldump <database> <view1> <view2> … > views.out

4) Drop the triggers on the current tables in the old_schema.

mysql> DROP TRIGGER <trigger_name>;
...

5) Restore the above dump files once all the “Base” tables found in step #2 are renamed.

mysql> RENAME TABLE <old_schema>.table_name TO <new_schema>.table_name;
...
$ mysql <new_schema> < views.out
$ mysql <new_schema> < stored_routines_triggers_events.out

Intricacies with above methods : We may need to update the GRANTS for users such that they match the correct schema_name. These could fixed with a simple UPDATE on mysql.columns_priv, mysql.procs_priv, mysql.tables_priv, mysql.db tables updating the old_schema name to new_schema and calling “Flush privileges;”. Although “method 2" seems a bit more complicated than the “method 1", this is totally scriptable. A simple bash script to carry out the above steps in proper sequence, can help you save space and time while renaming database schemas next time.

The Percona Remote DBA team have written a script called “rename_db” that works in the following way :

[root@dba~]# /tmp/rename_db
rename_db <server> <database> <new_database>

To demonstrate the use of this script, used a sample schema “emp”, created test triggers, stored routines on that schema. Will try to rename the database schema using the script, which takes some seconds to complete as opposed to time consuming dump/restore method.

In gitk --all:

• right click on the commit you want
• -> create new branch
• enter the name of an existing branch
• press return on the dialog that confirms replacing the old branch of that name.

Beware that re-creating instead of modifying the existing branch will lose tracking-branch information. (This is generally not a problem for simple use-cases where there's only one remote and your local branch has the same name as the corresponding branch in the remote. See comments for more details, thanks @mbdevpl for pointing out this downside.)

It would be cool if gitk had a feature where the dialog box had 3 options: overwrite, modify existing, or cancel.

Even if you're normally a command-line junkie like myself, git gui and gitk are quite nicely designed for the subset of git usage they allow. I highly recommend using them for what they're good at (i.e. selectively staging hunks into/out of the index in git gui, and also just committing. (ctrl-s to add a signed-off: line, ctrl-enter to commit.)

gitk is great for keeping track of a few branches while you sort out your changes into a nice patch series to submit upstream, or anything else where you need to keep track of what you're in the middle of with multiple branches.

I don't even have a graphical file browser open, but I love gitk/git gui.

my suggestion is...create role in oracle using

create role <role_name>;

then assign privileges to that role using

grant select on <table_name> to <role_name>;

then assign that group of privileges via that role to any user by using

grant  <role_name> to <user_name>...;

A timestamp is a point in time. Typically this can be represented by a number of milliseconds past an epoc (the Unix Epoc of Jan 1 1970 12AM UTC). The format of that point in time depends on the time zone. While it is the same point in time, the "hours value" is not the same among time zones and one must take into account the offset from the UTC.

Here's some code to illustrate. A point is time is captured in three different ways.

var moment = require( 'moment' );

var localDate = new Date();
var localMoment = moment();
var utcMoment = moment.utc();
var utcDate = new Date( utcMoment.format() );

//These are all the same
console.log( 'localData unix = ' + localDate.valueOf() );
console.log( 'localMoment unix = ' + localMoment.valueOf() );
console.log( 'utcMoment unix = ' + utcMoment.valueOf() );

//These formats are different
console.log( 'localDate = ' + localDate );
console.log( 'localMoment string = ' + localMoment.format() );
console.log( 'utcMoment string = ' + utcMoment.format() );
console.log( 'utcDate  = ' + utcDate );

//One to show conversion
console.log( 'localDate as UTC format = ' + moment.utc( localDate ).format() );
console.log( 'localDate as UTC unix = ' + moment.utc( localDate ).valueOf() );

Which outputs this:

localData unix = 1415806206570
localMoment unix = 1415806206570
utcMoment unix = 1415806206570
localDate = Wed Nov 12 2014 10:30:06 GMT-0500 (EST)
localMoment string = 2014-11-12T10:30:06-05:00
utcMoment string = 2014-11-12T15:30:06+00:00
utcDate  = Wed Nov 12 2014 10:30:06 GMT-0500 (EST)
localDate as UTC format = 2014-11-12T15:30:06+00:00
localDate as UTC unix = 1415806206570

In terms of milliseconds, each are the same. It is the exact same point in time (though in some runs, the later millisecond is one higher).

As far as format, each can be represented in a particular timezone. And the formatting of that timezone'd string looks different, for the exact same point in time!

Are you going to compare these time values? Just convert to milliseconds. One value of milliseconds is always less than, equal to or greater than another millisecond value.

Do you want to compare specific 'hour' or 'day' values and worried they "came from" different timezones? Convert to UTC first using moment.utc( existingDate ), and then do operations. Examples of those conversions, when coming out of the DB, are the last console.log calls in the example.

You can simply run

$(document).keyup(function(e) {
    console.log(e.keyCode);
});

to see the codes of pressed keys in the browser console.

Or you can find key codes here: https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/keyCode#Numpad_keys

Why just don't do something like this:

var ms = 86400;

var seconds = ms / 1000; //86.4

var minutes = seconds / 60; //1.4400000000000002

var hours = minutes / 60; //0.024000000000000004

var days = hours / 24; //0.0010000000000000002

And dealing with float precision e.g. Number(minutes.toFixed(5)) //1.44

Changes to Enterprise App Distribution Coming in iOS 9

iOS 9 introduces a new feature to help protect users from installing in-house apps from untrusted sources. While no new app signing or provisioning methods are required, the way your enterprise users manage in-house apps installed on their iOS 9 devices will change.

In-house apps installed using an MDM solution are explicitly trusted and will no longer prompt the user to trust the developer that signed and provisioned the app. If your enterprise app does not use an MDM solution, users who install your app for the first time will be prompted to trust the developer. All users who install your app for the first time will need an internet connection.

Using a new restriction, organizations can limit the apps installed on their devices to the in-house apps that they create. And a new interface in Settings allows users to see all enterprise apps installed from their organization.
