Programs & Examples On #Cairo

Try this: http://cairosvg.org/

The site says:

CairoSVG is written in pure python and only depends on Pycairo. It is known to work on Python 2.6 and 2.7.

Update November 25, 2016:

2.0.0 is a new major version, its changelog includes:

• Drop Python 2 support

You can use filter() to do that:

var tableRow = $("td").filter(function() {
    return $(this).text() == "foo";
}).closest("tr");

You can enable long path names using PowerShell:

Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem' -Name LongPathsEnabled -Type DWord -Value 1 

Another Version is to use a Group Policy in Computer Configuration/Administrative Templates/System/Filesystem:

One option that I've found to work is to set this function up as a Behavior.

The Behavior:

    public class WindowCloseBehavior : Behavior<Window>
{
    public bool Close
    {
        get { return (bool) GetValue(CloseTriggerProperty); }
        set { SetValue(CloseTriggerProperty, value); }
    }

    public static readonly DependencyProperty CloseTriggerProperty =
        DependencyProperty.Register("Close", typeof(bool), typeof(WindowCloseBehavior),
            new PropertyMetadata(false, OnCloseTriggerChanged));

    private static void OnCloseTriggerChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var behavior = d as WindowCloseBehavior;

        if (behavior != null)
        {
            behavior.OnCloseTriggerChanged();
        }
    }

    private void OnCloseTriggerChanged()
    {
        // when closetrigger is true, close the window
        if (this.Close)
        {
            this.AssociatedObject.Close();
        }
    }
}

On the XAML Window, you set up a reference to it and bind the Behavior's Close property to a Boolean "Close" property on your ViewModel:

xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
<i:Interaction.Behaviors>
    <behavior:WindowCloseBehavior Close="{Binding Close}" />
</i:Interaction.Behaviors>

So, from the View assign an ICommand to change the Close property on the ViewModel which is bound to the Behavior's Close property. When the PropertyChanged event is fired the Behavior fires the OnCloseTriggerChanged event and closes the AssociatedObject... which is the Window.

It's important to point out to readers stumbling upon this question when researching the subject in a broader fashion that the accepted answer's procedure is not required in the case you just want to split your project into files. It's only needed when you need multiple implementations of single classes. If your implementation per class is one, just one header file for each is enough.

Hence, from the accepted answer's example only this part is needed:

#ifndef MYHEADER_H
#define MYHEADER_H

//Class goes here, full declaration AND implementation

#endif

The #ifndef etc. preprocessor definitions allow it to be used multiple times.

PS. The topic becomes clearer once you realize C/C++ is 'dumb' and #include is merely a way to say "dump this text at this spot".

I tried with various approaches, but nothing worked. I kept getting "Cannot click element" or ElementNotVisibleException.

I was able to find the input, but I couldn't check it. Now, I'm clicking on the div that contains the checkbox and it works with following HTML (CSS based on Bootstrap).

 @foreach (var item in Model)
 {
     <tr>
         <td>
             <div id="@item.Id" class="checkbox">
                 <label><input type="checkbox" class="selectone" value="@item.Id"></label>
             </div>
         </td>
         <td val="@item.Id">
             @item.Detail
         </td>
         <td>
             <div>@item.Desc
             </div>
         </td>
         <td>
             @Html.ActionLink("Edit", "Create", new { EditId = item.Id })
         </td>
     </tr>
 }

This is the code for WebDriver:

var table = driver.FindElement(By.TagName("table"));
var tds = table.FindElements(By.TagName("td"));
var itemTds = tds.Where(t => t.Text == itemtocheck);
foreach (var td in itemTds)
{
    var CheckBoxTd = tds[tds.IndexOf(td) - 1];
    var val = td.GetAttribute("val");
    CheckBoxTd.FindElement(By.Id(val)).Click();
}

In this approach, I give the item id as id for the div and also add an attribute for td with that id. Once I find the td of the item that needs to be checked, I can find the div before that td and click it. We can also use the XPath query that supports before (here is the example http://learn-automation.com/how-to-write-dynamic-xpath-in-selenium/).

Try closing Android Studio/Eclipse if it's open. It worked for me.

I think the following would work well with lesser line of codes.

        session()->flash('toast', [
        'status' => 'success', 
        'body' => 'Body',
        'topic' => 'Success']
    );

I'm using a toaster package, but you can have something like this in your view.

             toastr.{{session('toast.status')}}(
              '{{session('toast.body')}}', 
              '{{session('toast.topic')}}'
             );

Inserting Space in emailId field after every 8 characters

public string BreakEmailId(string emailId) {
    string returnVal = string.Empty;
    if (emailId.Length > 8) {           
        for (int i = 0; i < emailId.Length; i += 8) {
            returnVal += emailId.Substring(i, 8) + " ";
        }
    }

    return returnVal;
}

You have two versions of ADB

$ /usr/local/bin/adb version
Android Debug Bridge version 1.0.36
Revision 0e9850346394-android

and

$ /Users/user/Library/Android/sdk/platform-tools/adb version
Android Debug Bridge version 1.0.39
Revision 3db08f2c6889-android

You could see which one your PATH is pointing to (echo $PATH) but I fixed it with a adb stop-server on one version and a adb start-server on the other.

Emmanuel,

I think the extra info should be put before starting the activity otherwise the data won't be available yet if you're accessing it in the onCreate method of NextActivity.

Intent myIntent = new Intent(CurrentActivity.this, NextActivity.class);

myIntent.putExtra("key", value);

CurrentActivity.this.startActivity(myIntent);

You need to add a name attribute to your dropdown list, then you need to add a required attribute, and then you can reference the error using myForm.[input name].$error.required:

HTML:

        <form name="myForm" ng-controller="Ctrl" ng-submit="save(myForm)" novalidate>
        <input type="text" name="txtServiceName" ng-model="ServiceName" required>
<span ng-show="myForm.txtServiceName.$error.required">Enter Service Name</span>
<br/>
          <select name="service_id" class="Sitedropdown" style="width: 220px;"          
                  ng-model="ServiceID" 
                  ng-options="service.ServiceID as service.ServiceName for service in services"
                  required> 
            <option value="">Select Service</option> 
          </select> 
          <span ng-show="myForm.service_id.$error.required">Select service</span>

        </form>

    Controller:

        function Ctrl($scope) {
          $scope.services = [
            {ServiceID: 1, ServiceName: 'Service1'},
            {ServiceID: 2, ServiceName: 'Service2'},
            {ServiceID: 3, ServiceName: 'Service3'}
          ];

    $scope.save = function(myForm) {
    console.log('Selected Value: '+ myForm.service_id.$modelValue);
    alert('Data Saved! without validate');
    };
        }

Here's a working plunker.

You need to write a little PHP code. When user first click tab you can check is he like the page or not. Below is the sample code

include_once("facebook.php");

    // Create our Application instance.
    $facebook = new Facebook(array(
      'appId'  => FACEBOOK_APP_ID,
      'secret' => FACEBOOK_SECRET,
      'cookie' => true,
    ));

$signed_request = $facebook->getSignedRequest();

// Return you the Page like status
$like_status = $signed_request["page"]["liked"];

if($like_status)
{
    echo 'User Liked the page';
    // Place some content you wanna show to user

}else{
    echo 'User do not liked the page';
    // Place some content that encourage user to like the page
}

Along with other methods it is also good to have pairplot which will give scatter plot for all the cases-

import pandas as pd
import numpy as np
import seaborn as sns
rs = np.random.RandomState(0)
df = pd.DataFrame(rs.rand(10, 10))
sns.pairplot(df)

To do this on github.com:

1. Go to your project.
2. Click on the "Commits".
3. Click on the <> ("Browse the repository at this point in the history") on the commit you want to branch from.
4. Click on the "tree: xxxxxx" up in the upper left. Just below the language statistics bar, you'll get the option to "Find or Create Branch" (just type in a new branch name there)

In angular 1.4 +, in addition to adding the dependency

angular.module('myApp', ['ngRoute'])

,we also need to reference the separate angular-route.js file

<script src="angular.js">
<script src="angular-route.js">

see https://docs.angularjs.org/api/ngRoute

Android R Update:

From Android R, this method always returns false. Google says that this is done "to protect goat privacy":

/**
 * Used to determine whether the user making this call is subject to
 * teleportations.
 *
 * <p>As of {@link android.os.Build.VERSION_CODES#LOLLIPOP}, this method can
 * now automatically identify goats using advanced goat recognition technology.</p>
 *
 * <p>As of {@link android.os.Build.VERSION_CODES#R}, this method always returns
 * {@code false} in order to protect goat privacy.</p>
 *
 * @return Returns whether the user making this call is a goat.
 */
public boolean isUserAGoat() {
    if (mContext.getApplicationInfo().targetSdkVersion >= Build.VERSION_CODES.R) {
        return false;
    }
    return mContext.getPackageManager()
            .isPackageAvailable("com.coffeestainstudios.goatsimulator");
}

Previous answer:

From their source, the method used to return false until it was changed in API 21.

/**
 * Used to determine whether the user making this call is subject to
 * teleportations.
 * @return whether the user making this call is a goat 
 */
public boolean isUserAGoat() {
    return false;
}

It looks like the method has no real use for us as developers. Someone has previously stated that it might be an Easter egg.

In API 21 the implementation was changed to check if there is an installed app with the package com.coffeestainstudios.goatsimulator

/**
 * Used to determine whether the user making this call is subject to
 * teleportations.
 *
 * <p>As of {@link android.os.Build.VERSION_CODES#LOLLIPOP}, this method can
 * now automatically identify goats using advanced goat recognition technology.</p>
 *
 * @return Returns true if the user making this call is a goat.
 */
public boolean isUserAGoat() {
    return mContext.getPackageManager()
            .isPackageAvailable("com.coffeestainstudios.goatsimulator");
}

Here is the source and the change.

Looks to me like you need to set the yellow on #doc3 and then get rid of the white that is called out on the #yui-main (which is covering up the color of the #doc3). This gets you yellow between header and footer.

You have to install npm install env-cmd

Make .env in the root directory and update like this & REACT_APP_ is the compulsory prefix for the variable name.

REACT_APP_NODE_ENV="production"
REACT_APP_DB="http://localhost:5000"

Update package.json

  "scripts": {
    "start": "env-cmd react-scripts start",
    "build": "env-cmd react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  }

Use the dateFormat option

 $(function(){
        $("#to").datepicker({ dateFormat: 'yy-mm-dd' });
        $("#from").datepicker({ dateFormat: 'yy-mm-dd' }).bind("change",function(){
            var minValue = $(this).val();
            minValue = $.datepicker.parseDate("yy-mm-dd", minValue);
            minValue.setDate(minValue.getDate()+1);
            $("#to").datepicker( "option", "minDate", minValue );
        })
    });

compileSdkVersion

The compileSdkVersion is the version of the API the app is compiled against. This means you can use Android API features included in that version of the API (as well as all previous versions, obviously). If you try and use API 16 features but set compileSdkVersion to 15, you will get a compilation error. If you set compileSdkVersion to 16 you can still run the app on a API 15 device as long as your app's execution paths do not attempt to invoke any APIs specific to API 16.

targetSdkVersion

The targetSdkVersion has nothing to do with how your app is compiled or what APIs you can utilize. The targetSdkVersion is supposed to indicate that you have tested your app on (presumably up to and including) the version you specify. This is more like a certification or sign off you are giving the Android OS as a hint to how it should handle your app in terms of OS features.

For example, as the documentation states:

For example, setting this value to "11" or higher allows the system to apply a new default theme (Holo) to your app when running on Android 3.0 or higher...

The Android OS, at runtime, may change how your app is stylized or otherwise executed in the context of the OS based on this value. There are a few other known examples that are influenced by this value and that list is likely to only increase over time.

For all practical purposes, most apps are going to want to set targetSdkVersion to the latest released version of the API. This will ensure your app looks as good as possible on the most recent Android devices. If you do not specify the targetSdkVersion, it defaults to the minSdkVersion.

By far the easiest way to create DOC files on Linux, using PHP is with the Zend Framework component phpLiveDocx.

From the project web site:

"phpLiveDocx allows developers to generate documents by combining structured data from PHP with a template, created in a word processor. The resulting document can be saved as a PDF, DOCX, DOC or RTF file. The concept is the same as with mail-merge."

use this JavaScript code:

<script>
    setTimeout(function(){
       window.location.href = 'form2.html';
    }, 5000);
</script>

From a post by Robert Martin in comp.object:

Association represents the ability of one instance to send a message to another instance. This is typically implemented with a pointer or reference instance variable, although it might also be implemented as a method argument, or the creation of a local variable.

//[Example:]

//|A|----------->|B|

class A
{
  private:
    B* itsB;
};

Aggregation [...] is the typical whole/part relationship. This is exactly the same as an association with the exception that instances cannot have cyclic aggregation relationships (i.e. a part cannot contain its whole).

//[Example:]

//|Node|<>-------->|Node|

class Node
{
  private:
    vector<Node*> itsNodes;
};

The fact that this is aggregation means that the instances of Node cannot form a cycle. Thus, this is a Tree of Nodes not a graph of Nodes.

Composition [...] is exactly like Aggregation except that the lifetime of the 'part' is controlled by the 'whole'. This control may be direct or transitive. That is, the 'whole' may take direct responsibility for creating or destroying the 'part', or it may accept an already created part, and later pass it on to some other whole that assumes responsibility for it.

//[Example:]

//|Car|<#>-------->|Carburetor|

class Car
{
  public:
    virtual ~Car() {delete itsCarb;}
  private:
    Carburetor* itsCarb
};

I've added the Initial Catalog to your connection string. I've also abandonded the ADODB.Command syntax in favor of simply creating my own SQL statement and open the recordset on that variable.

Hope this helps.

Sub GetDataFromADO()
    'Declare variables'
        Set objMyConn = New ADODB.Connection
        Set objMyRecordset = New ADODB.Recordset
        Dim strSQL As String

    'Open Connection'
        objMyConn.ConnectionString = "Provider=SQLOLEDB;Data Source=localhost;Initial Catalog=MyDatabase;User ID=abc;Password=abc;"
        objMyConn.Open

    'Set and Excecute SQL Command'
        strSQL = "select * from myTable"

    'Open Recordset'
        Set objMyRecordset.ActiveConnection = objMyConn
        objMyRecordset.Open strSQL            

    'Copy Data to Excel'
        ActiveSheet.Range("A1").CopyFromRecordset (objMyRecordset)

End Sub

Swift 3/4 with @IBDesignable

While almost all the above solutions work fine but I would suggest an @IBDesignable custom class for this.

@IBDesignable
class CustomLabel: UILabel {

    /*
    // Only override draw() if you perform custom drawing.
    // An empty implementation adversely affects performance during animation.
    override func draw(_ rect: CGRect) {
        // Drawing code
    }
    */

    @IBInspectable var borderColor: UIColor = UIColor.white {
        didSet {
            layer.borderColor = borderColor.cgColor
        }
    }

    @IBInspectable var borderWidth: CGFloat = 2.0 {
        didSet {
            layer.borderWidth = borderWidth
        }
    }

    @IBInspectable var cornerRadius: CGFloat = 0.0 {
        didSet {
            layer.cornerRadius = cornerRadius
        }
    }
}

Can I suggest that you reload it into a non-DOM image object? If it's cached, this will take no time at all, and the onload will still fire. If it isn't cached, it will fire the onload when the image is loaded, which should be the same time as the DOM version of the image finishes loading.

Javascript:

$(document).ready(function() {
    var tmpImg = new Image() ;
    tmpImg.src = $('#img').attr('src') ;
    tmpImg.onload = function() {
        // Run onload code.
    } ;
}) ;

Updated (to handle multiple images and with correctly ordered onload attachment):

$(document).ready(function() {
    var imageLoaded = function() {
        // Run onload code.
    }
    $('#img').each(function() {
        var tmpImg = new Image() ;
        tmpImg.onload = imageLoaded ;
        tmpImg.src = $(this).attr('src') ;
    }) ;
}) ;

I did a project on this. You can look at my github repo:

https://github.com/nishant-boro/django-rest-framework-download-expert

This module provides a simple way to serve files for download in django rest framework using Apache module Xsendfile. It also has an additional feature of serving downloads only to users belonging to a particular group

Please note the fact that: n&(n-1) always eliminates the least significant 1.

Hence we can write the code for calculating the number of 1's as follows:

count=0;
while(n!=0){
  n = n&(n-1);
  count++;
}
cout<<"Number of 1's in n is: "<<count;

The complexity of the program would be: number of 1's in n (which is constantly < 32).

Don't forgot to use important browsers specific attributes:

align-items: center; -->

-webkit-box-align: center;
-moz-box-align: center;
-ms-flex-align: center;
-webkit-align-items: center;
align-items: center;

justify-content: center; -->

-webkit-box-pack: center;
-moz-box-pack: center;
-ms-flex-pack: center;
-webkit-justify-content: center;
justify-content: center;

You could read this two links for better understanding flex: http://css-tricks.com/almanac/properties/j/justify-content/ and http://ptb2.me/flexbox/

Good Luck.

If you have problems with accessing to the path, maybe you need to put this:

$root = $_SERVER['DOCUMENT_ROOT'];
$path = "/cv/"; 

// Open the folder
 $dir_handle = @opendir($root . $path) or die("Unable to open $path");

As much as I love XAML, for this kinds of tasks I switch to code behind. Attached behaviors are a good pattern for this. Keep in mind, Expression Blend 3 provides a standard way to program and use behaviors. There are a few existing ones on the Expression Community Site.

I believe the simpliest aproach is to :

1. Create AMI image of existing instance.
2. Launch new EC2 instance using AMI image (crated by step 1) with new key pair.
3. Login to new EC2 instance with new key.

In woocommerce,

Get regular price :

$price = get_post_meta( get_the_ID(), '_regular_price', true);
// $price will return regular price

Get sale price:

$sale = get_post_meta( get_the_ID(), '_sale_price', true);
// $sale will return sale price

Although I guess you do not need an answer any longer, I am giving the solution for those who will come to see this post.

\def\@endpart{\vfil\newpage

It is "\newpage" at the first line of this fragment that adds a redundant blank page after the part header page. So you must redefine the command \@endpart. Add the following snippet to the beggining of your tex file.

\makeatletter
\renewcommand\@endpart{\vfil
              \if@twoside
                \null

Anchors will need to be a different display type than their default to take a height. display:inline-block; or display:block;.

Also check on line-height which might be interesting with this.

Use math.ceil to round up:

>>> import math
>>> math.ceil(5.4)
6.0

NOTE: The input should be float.

If you need an integer, call int to convert it:

>>> int(math.ceil(5.4))
6

BTW, use math.floor to round down and round to round to nearest integer.

>>> math.floor(4.4), math.floor(4.5), math.floor(5.4), math.floor(5.5)
(4.0, 4.0, 5.0, 5.0)
>>> round(4.4), round(4.5), round(5.4), round(5.5)
(4.0, 5.0, 5.0, 6.0)
>>> math.ceil(4.4), math.ceil(4.5), math.ceil(5.4), math.ceil(5.5)
(5.0, 5.0, 6.0, 6.0)

You shouldn't rely on the order of elements by using prev or next. Just use the for attribute of the label, as it should correspond to the ID of the element you're currently manipulating:

var label = $("label[for='" + $(this).attr('id') + "']");

However, there are some cases where the label will not have for set, in which case the label will be the parent of its associated control. To find it in both cases, you can use a variation of the following:

var label = $('label[for="' + $(this).attr('id') + '"]');

if(label.length <= 0) {
    var parentElem = $(this).parent(),
        parentTagName = parentElem.get(0).tagName.toLowerCase();

    if(parentTagName == "label") {
        label = parentElem;
    }
}

I hope this helps!

You cannot use || operators in between 2 case. But you can use multiple case values without using a break between them. The program will then jump to the respective case and then it will look for code to execute until it finds a "break". As a result these cases will share the same code.

switch(value) 
{ 
    case 0: 
    case 1: 
        // do stuff for if case 0 || case 1 
        break; 
    // other cases 
    default: 
        break; 
}

To update @Sunil answer: Under Windows, Miniconda has a regular uninstaller. Go to the menu "Settings/Apps/Apps&Features", or click the Start button, type "uninstall", then click on "Add or Remove Programs" and finally on the Miniconda uninstaller.

In addition to this answer, note that in Node.js if you access JSON with the array syntax [] all nested JSON keys should follow that syntax

This is the wrong way

json.first.second.third['comment']

and will will give you the 'undefined' error.

This is the correct way

json['first']['second']['third']['comment']

Java solution

• The "-" is used to left indent

• The "15" makes the String's minimum length it takes up be 15

• The "s" (which is a few characters after %) will be substituted by our String
• The 0 pads our integer with 0s on the left
• The 3 makes our integer be a minimum length of 3

.data("events") has been removed in versions 1.9 and 2.0beta, so you cant any longer rely on those solutions.

Use .apply() to have the same access to arguments in function b, like this:

function a(){
    b.apply(null, arguments);
}
function b(){
   alert(arguments); //arguments[0] = 1, etc
}
a(1,2,3);?

You're missing the 32 bit libc dev package:

On Ubuntu it's called libc6-dev-i386 - do sudo apt-get install libc6-dev-i386. See below for extra instructions for Ubuntu 12.04.

On Red Hat distros, the package name is glibc-devel.i686 (Thanks to David Gardner's comment).

On CentOS 5.8, the package name is glibc-devel.i386 (Thanks to JimKleck's comment).

On CentOS 6 / 7, the package name is glibc-devel.i686.

On SLES it's called glibc-devel-32bit - do zypper in glibc-devel-32bit.

On Gentoo it's called sys-libs/glibc - do emerge -1a sys-libs/gcc [source] (Note : One may use equery to confirm this is correct; do equery belongs belongs /usr/include/gnu/stubs-32.h)

On ArchLinux, the package name is lib32-glibc - do pacman -S lib32-glibc.

Are you using Ubuntu 12.04? There is a known problem that puts the files in a non standard location. You'll also need to do:

export LIBRARY_PATH=/usr/lib/$(gcc -print-multiarch)
export C_INCLUDE_PATH=/usr/include/$(gcc -print-multiarch)
export CPLUS_INCLUDE_PATH=/usr/include/$(gcc -print-multiarch)

somewhere before you build (say in your .bashrc).

If you are also compiling C++ code, you will also need the 32 bit stdc++ library. If you see this warning:

.... /usr/bin/ld: cannot find -lstdc++ ....

On Ubuntu you will need to do sudo apt-get install g++-multilib

On CentOS 5 you will need to do yum install libstdc++-devel.i386

On CentOS 6 you will need to do yum install libstdc++-devel.i686

Please feel free to edit in the packages for other systems.

I got this error because I had a dependency on another module that was not loaded.

angular.module("app", ["kendo.directives"]).controller("MyCtrl", function(){}...

so even though I had all the Angular modules, I didn't have the kendo one.

Which specific index? If you want 'Add New' to be first on the dropdownlist you can add it though the code like this:

<asp:DropDownList ID="DropDownList1" AppendDataBoundItems="true" runat="server">
     <asp:ListItem Text="Add New" Value="0" />
</asp:DropDownList>

If you want to add it at a different index, maybe the last then try:

ListItem lst = new ListItem ( "Add New" , "0" );

DropDownList1.Items.Insert( DropDownList1.Items.Count-1 ,lst);

You could use IllegalArgumentException:

public void speedDown(int decrement)
{
    if(speed - decrement < 0){
        throw new IllegalArgumentException("Final speed can not be less than zero");
    }else{
        speed -= decrement;
    }
}

Have you thinked about using instanceof ? Like, say

if(myObject instanceof Collection) {
     Collection myCollection = (Collection) myObject;

Although not that pure OOP style, it is however largely used for so-called "type escalation".

I modified your solution to chain over multiple properties:

public static string GetPropertyName<T>(Expression<Func<T>> propertyLambda)
{
    MemberExpression me = propertyLambda.Body as MemberExpression;
    if (me == null)
    {
        throw new ArgumentException("You must pass a lambda of the form: '() => Class.Property' or '() => object.Property'");
    }

    string result = string.Empty;
    do
    {
        result = me.Member.Name + "." + result;
        me = me.Expression as MemberExpression;
    } while (me != null);

    result = result.Remove(result.Length - 1); // remove the trailing "."
    return result;
}

Usage:

string name = GetPropertyName(() => someObject.SomeProperty.SomeOtherProperty);
// returns "SomeProperty.SomeOtherProperty"

Use the .date() method to convert a datetime to a date:

if item_date.date() > from_date:

Alternatively, you could use datetime.today() instead of date.today(). You could use

from_date = from_date.replace(hour=0, minute=0, second=0, microsecond=0)

to eliminate the time part afterwards.

Make sure to resolve/reject the promises used in the test cases, be it spies or stubs make sure they resolve/reject.

# To do it for all names
df[] <- lapply( df, factor) # the "[]" keeps the dataframe structure
 col_names <- names(df)
# to do it for some names in a vector named 'col_names'
df[col_names] <- lapply(df[col_names] , factor)

Explanation. All dataframes are lists and the results of [ used with multiple valued arguments are likewise lists, so looping over lists is the task of lapply. The above assignment will create a set of lists that the function data.frame.[<- should successfully stick back into into the dataframe, df

Another strategy would be to convert only those columns where the number of unique items is less than some criterion, let's say fewer than the log of the number of rows as an example:

cols.to.factor <- sapply( df, function(col) length(unique(col)) < log10(length(col)) )
df[ cols.to.factor] <- lapply(df[ cols.to.factor] , factor)

I was working with EasyRepro, and when I debugged my code it was clicking on the element which is visible and enabled, and not navigating as expected. But finally I understood the root cause for the issue.

My Chrome was zoomed out 90%

Once i reset the zoom level, it clicked on the correct element and successfully navigated to next page.

Move script tag at the end of BODY instead of HEAD because in current code when the script is computed html element doesn't exist in document.

Since you don't want to you jquery. Use window.onload or document.onload to execute the entire piece of code that you have in current script tag. window.onload vs document.onload

double.Parse("-"); raises an exception, while double.TryParse("-", out parsed); parses to 0 so I guess TryParse does more complex conversions.

Some time ago I used JAD (JAva Decompiler) to achieve this - I do not think IntelliJ's decompiler was incorporated with exporting in mind. It is more of a tool to help look through classes where sources are not available.

JAD is still available for download, but I do not think anyone maintains it anymore: http://varaneckas.com/jad/

There were numerous plugins for it, namely Jadclipse (you guessed it, a way to use JAD in Eclipse - see decompiled classes where code is not available :)).

As already noted by gezzed in his comment, meanwhile there is a good solution (described in Polling must die: triggering Jenkins builds from a Git hook):

• Set the Jenkins job's build trigger to Poll SCM, but do not specify a schedule.

• Create a GitHub post-receive trigger to notify the URL

  http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>?token=<get token from git to build remotely>
  

• This will trigger all builds that poll the specified Git repository.

• However, polling actually checks whether anything has been pushed to the used branch.

It works perfectly.

Assuming that winrar.exe is in the PATH, then Runtime.exec is capable of finding it, if it is not, you will need to supply the fully qualified path to it, for example, assuming winrar.exe is installed in C:/Program Files/WinRAR you would need to use something like...

p=r.exec("C:/Program Files/WinRAR/winrar x h:\\myjar.jar *.* h:\\new");

Personally, I would recommend that you use ProcessBuilder as it has some additional configuration abilities amongst other things. Where possible, you should also separate your command and parameters into separate String elements, it deals with things like spaces much better then a single String variable, for example...

ProcessBuilder pb = new ProcessBuilder(
    "C:/Program Files/WinRAR/winrar",
    "x",
    "myjar.jar",
    "*.*",
    "new");
pb.directory(new File("H:/"));
pb. redirectErrorStream(true);

Process p = pb.start();

Don't forget to read the contents of the InputStream from the process, as failing to do so may stall the process

In order to use nslookup, host or gethostbyname() then the target's name will need to be registered with DNS or statically defined in the hosts file on the machine running your program. Yes, you could connect to the target with SSH or some other application and query it directly, but for a generic solution you'll need some sort of DNS entry for it.

You can't select a sheet in a non-active workbook.

You must first activate the workbook, then you can select the sheet.

workbooks("A").activate
workbooks("A").worksheets("B").select 

When you use Activate it automatically activates the workbook.

Note you can select >1 sheet in a workbook:

activeworkbook.sheets(array("sheet1","sheet3")).select

but only one sheet can be Active, and if you activate a sheet which is not part of a multi-sheet selection then those other sheets will become un-selected.

It's new features since the version 3.3.0 http://www.rabbitmq.com/release-notes/README-3.3.0.txt

server
------

...
25603 prevent access using the default guest/guest credentials except via
      localhost.

If you want enable the guest user read this or this RabbitMQ 3.3.1 can not login with guest/guest

# remove guest from loopback_users in rabbitmq.config like this
[{rabbit, [{loopback_users, []}]}].
# It is danger for default user and default password for remote access
# better to change password 
rabbitmqctl  change_password guest NEWPASSWORD

If you want create a new user with admin grants:

rabbitmqctl add_user test test
rabbitmqctl set_user_tags test administrator
rabbitmqctl set_permissions -p / test ".*" ".*" ".*"

Now you can access using test test.

FYI, I believe Bjarne Stroustrup is quoted as saying that C-style casts are to be avoided and that you should use static_cast or dynamic_cast if at all possible.

Not a real array, but objs are all associative arrays in javascript.

I chose not to use a real array with [] and [].push because technically, you can have multiple ID's on a page even though that is incorrect to do so. So just another option in case some html has duplicated ID's

$(function() {

       var oArr = {};
       $("*[id]").each(function() {
           var id = $(this).attr('id');
           if (!oArr[id]) oArr[id] = true;
       });

       for (var prop in oArr)
           alert(prop);

   });

you can do it with pd.date_range() and Timestamp. Let's say you have read a csv file with a date column using parse_dates option:

df = pd.read_csv('my_file.csv', parse_dates=['my_date_col'])

Then you can define a date range index :

rge = pd.date_range(end='15/6/2020', periods=2)

and then filter your values by date thanks to a map:

df.loc[df['my_date_col'].map(lambda row: row.date() in rge)]

Interfaces allow statically typed languages to support polymorphism. An Object Oriented purist would insist that a language should provide inheritance, encapsulation, modularity and polymorphism in order to be a fully-featured Object Oriented language. In dynamically-typed - or duck typed - languages (like Smalltalk,) polymorphism is trivial; however, in statically typed languages (like Java or C#,) polymorphism is far from trivial (in fact, on the surface it seems to be at odds with the notion of strong typing.)

Let me demonstrate:

In a dynamically-typed (or duck typed) language (like Smalltalk), all variables are references to objects (nothing less and nothing more.) So, in Smalltalk, I can do this:

|anAnimal|    
anAnimal := Pig new.
anAnimal makeNoise.

anAnimal := Cow new.
anAnimal makeNoise.

That code:

1. Declares a local variable called anAnimal (note that we DO NOT specify the TYPE of the variable - all variables are references to an object, no more and no less.)
2. Creates a new instance of the class named "Pig"
3. Assigns that new instance of Pig to the variable anAnimal.
4. Sends the message makeNoise to the pig.
5. Repeats the whole thing using a cow, but assigning it to the same exact variable as the Pig.

The same Java code would look something like this (making the assumption that Duck and Cow are subclasses of Animal:

Animal anAnimal = new Pig();
duck.makeNoise();

anAnimal = new Cow();
cow.makeNoise();

That's all well and good, until we introduce class Vegetable. Vegetables have some of the same behavior as Animal, but not all. For example, both Animal and Vegetable might be able to grow, but clearly vegetables don't make noise and animals cannot be harvested.

In Smalltalk, we can write this:

|aFarmObject|
aFarmObject := Cow new.
aFarmObject grow.
aFarmObject makeNoise.

aFarmObject := Corn new.
aFarmObject grow.
aFarmObject harvest.

This works perfectly well in Smalltalk because it is duck-typed (if it walks like a duck, and quacks like a duck - it is a duck.) In this case, when a message is sent to an object, a lookup is performed on the receiver's method list, and if a matching method is found, it is called. If not, some kind of NoSuchMethodError exception is thrown - but it's all done at runtime.

But in Java, a statically typed language, what type can we assign to our variable? Corn needs to inherit from Vegetable, to support grow, but cannot inherit from Animal, because it does not make noise. Cow needs to inherit from Animal to support makeNoise, but cannot inherit from Vegetable because it should not implement harvest. It looks like we need multiple inheritance - the ability to inherit from more than one class. But that turns out to be a pretty difficult language feature because of all the edge cases that pop up (what happens when more than one parallel superclass implement the same method?, etc.)

Along come interfaces...

If we make Animal and Vegetable classes, with each implementing Growable, we can declare that our Cow is Animal and our Corn is Vegetable. We can also declare that both Animal and Vegetable are Growable. That lets us write this to grow everything:

List<Growable> list = new ArrayList<Growable>();
list.add(new Cow());
list.add(new Corn());
list.add(new Pig());

for(Growable g : list) {
   g.grow();
}

And it lets us do this, to make animal noises:

List<Animal> list = new ArrayList<Animal>();
list.add(new Cow());
list.add(new Pig());
for(Animal a : list) {
  a.makeNoise();
}

The advantage to the duck-typed language is that you get really nice polymorphism: all a class has to do to provide behavior is provide the method. As long as everyone plays nice, and only sends messages that match defined methods, all is good. The downside is that the kind of error below isn't caught until runtime:

|aFarmObject|
aFarmObject := Corn new.
aFarmObject makeNoise. // No compiler error - not checked until runtime.

Statically-typed languages provide much better "programming by contract," because they will catch the two kinds of error below at compile-time:

// Compiler error: Corn cannot be cast to Animal.
Animal farmObject = new Corn();  
farmObject makeNoise();

--

// Compiler error: Animal doesn't have the harvest message.
Animal farmObject = new Cow();
farmObject.harvest(); 

So....to summarize:

1. Interface implementation allows you to specify what kinds of things objects can do (interaction) and Class inheritance lets you specify how things should be done (implementation).

2. Interfaces give us many of the benefits of "true" polymorphism, without sacrificing compiler type checking.

You can use this for the Width of your DataTemplate:

Width="{Binding ActualWidth,RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ScrollContentPresenter}}}"

Make sure your DataTemplate root has Margin="0" (you can use some panel as the root and set the Margin to the children of that root)

This is my code, to start/stop a Windows service using SC command. If the service fails to start/stop, it will print a log info. You can try it by Inno Setup.

{ start a service }
Exec(ExpandConstant('{cmd}'), '/C sc start ServiceName', '',
     SW_HIDE, ewWaitUntilTerminated, ResultCode);
Log('sc start ServiceName:'+SysErrorMessage(ResultCode));

{ stop a service }
Exec(ExpandConstant('{cmd}'), '/C sc stop ServiceName', '',
     SW_HIDE, ewWaitUntilTerminated, ResultCode);
Log('sc stop ServiceName:'+SysErrorMessage(ResultCode));

If you use ng > 1.2, here is an example of using ng-repeat-start/end without generating unnecessary tags:

<html>_x000D_
  <head>_x000D_
    <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
    <script>_x000D_
      angular.module('mApp', []);_x000D_
    </script>_x000D_
  </head>_x000D_
  <body ng-app="mApp">_x000D_
    <table border="1" width="100%">_x000D_
      <tr ng-if="0" ng-repeat-start="elem in [{k: 'A', v: ['a1','a2']}, {k: 'B', v: ['b1']}, {k: 'C', v: ['c1','c2','c3']}]"></tr>_x000D_
_x000D_
      <tr>_x000D_
        <td rowspan="{{elem.v.length}}">{{elem.k}}</td>_x000D_
        <td>{{elem.v[0]}}</td>_x000D_
      </tr>_x000D_
      <tr ng-repeat="v in elem.v" ng-if="!$first">_x000D_
        <td>{{v}}</td>_x000D_
      </tr>_x000D_
_x000D_
      <tr ng-if="0" ng-repeat-end></tr>_x000D_
    </table>_x000D_
  </body>_x000D_
</html>

The important point: for tags used for ng-repeat-start and ng-repeat-end set ng-if="0", to let not be inserted in the page. In this way the inner content will be handled exactly as it is in knockoutjs (using commands in <!--...-->), and there will be no garbage.

It's simple, use $.getJSON() function and in your URL just include

Same Object Not Found problem here - both in Xampp as well as in Wamp. It turns out the root name of "phpmyadmin" was "PhpMyAdmin". I got rid of all the capitals, renaming the folder to "phpmyadmin", and after a couple of reloads phpmyadmin was working.

Since PyYAML's yaml.load() function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:

import yaml
with open('tree.yaml', 'r') as f:
    doc = yaml.load(f)

To access branch1 text you would use:

txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"

because, in your YAML document, the value of the branch1 key is under the treeroot key.

// c++03
string s = "(555) 555-5555";

s.erase(remove_if(s.begin(), s.end(), ptr_fun(::ispunct)), s.end());

Note: It's posible you need write ptr_fun<int, int> rather than simple ptr_fun

A solution without reference to a Bean:

<h:button value="login" 
        outcome="content/configuration.xhtml?i=1" />

public static class Cloner
{
    public static T Clone<T>(this T item)
    {
        FieldInfo[] fis = item.GetType().GetFields(BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic);
        object tempMyClass = Activator.CreateInstance(item.GetType());
        foreach (FieldInfo fi in fis)
        {
            if (fi.FieldType.Namespace != item.GetType().Namespace)
                fi.SetValue(tempMyClass, fi.GetValue(item));
            else
            {
                object obj = fi.GetValue(item);
                if (obj != null)
                    fi.SetValue(tempMyClass, obj.Clone());
            }
        }
        return (T)tempMyClass;
    }
}

The function match works on vectors:

x <- sample(1:10)
x
# [1]  4  5  9  3  8  1  6 10  7  2
match(c(4,8),x)
# [1] 1 5

match only returns the first encounter of a match, as you requested. It returns the position in the second argument of the values in the first argument.

For multiple matching, %in% is the way to go:

x <- sample(1:4,10,replace=TRUE)
x
# [1] 3 4 3 3 2 3 1 1 2 2
which(x %in% c(2,4))
# [1]  2  5  9 10

%in% returns a logical vector as long as the first argument, with a TRUE if that value can be found in the second argument and a FALSE otherwise.

HTTP is a communications protocol that transports messages over a network. SOAP is a protocol to exchange XML-based messages that can use HTTP to transport those messages. Rest is a protocol to exchange any(XML or JSON) messages that can use HTTP to transport those messages.

How to get append input field value as json like

You can make an auth section in your .hgrc or Mercurial.ini file, like so:

[auth]
bb.prefix = https://bitbucket.org/repo/path
bb.username = foo
bb.password = foo_passwd

The ‘bb’ part is an arbitrary identifier and is used to match prefix with username and password - handy for managing different username/password combos with different sites (prefix)

You can also only specify the user name, then you will just have to type your password when you push.

I would also recommend to take a look at the keyring extension. Because it stores the password in your system’s key ring instead of a plain text file, it is more secure. It is bundled with TortoiseHg on Windows, and there is currently a discussion about distributing it as a bundled extension on all platforms.

I would say to set up the font size change in your CSS stylesheet file.

I'm pretty sure that you want all text at the same size for all your form fields. Adding inline styles in your HTML will add to many lines at the end... plus you would need to add it to the other types of form fields such as <select>.

HTML:

<div id="cForm">
    <form method="post">
        <input type="text" name="name" placeholder="Name" data-required="true">
        <option value="" selected="selected" >Choose Category...</option>
    </form>
</div>

CSS:

input, select {
    font-size: 18px;
}

In the MathMethod.py file:

from multipledispatch import dispatch
@dispatch(int, int)
def Add(a, b):
   return a + b 
@dispatch(int, int, int)  
def Add(a, b, c):
   return a + b + c 
@dispatch(int, int, int, int)    
def Add(a, b, c, d):
   return a + b + c + d

In the Main.py file

import MathMethod as MM 
print(MM.Add(200, 1000, 1000, 200))

We can overload the method by using multipledispatch.

Most simple approach would be using the Image tag.

<Button Name="btn" Width="26" Height="26" Click="btnClick"> 
   <Image Source="Resource/btn-icon.png"/>
</Button>

Suppose your image file is added in Resource folder

In Express 4.x you can use req.hostname, which returns the domain name, without port. i.e.:

Here's the link that gives me the answer and we use gmail:

Install the "fake sendmail for windows". If you are not using XAMPP you can download it here: http://glob.com.au/sendmail/sendmail.zip

Modify the php.ini file to use it (commented out the other lines):

mail function

For Win32 only.

SMTP = smtp.gmail.com
smtp_port = 25
For Win32 only.
sendmail_from = <e-mail username>@gmail.com

For Unix only.

You may supply arguments as well (default: sendmail -t -i).

sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(ignore the "Unix only" bit, since we actually are using sendmail)

You then have to configure the "sendmail.ini" file in the directory where sendmail was installed:

sendmail

smtp_server=smtp.gmail.com
smtp_port=25
error_logfile=error.log
debug_logfile=debug.log
auth_username=<username>
auth_password=<password>
force_sender=<e-mail username>@gmail.com

@rene-pot is correct. You will however have a not-allowed sign on the desktop version of the website. Way around this, apply the readonly="true" to a div that will show up on the mobile view only and not on desktop. See what we did here http://www.naivashahotels.com/naivasha-hotels/lake-naivasha-country-club/

With Java 8's lambdas, a convenient way is to use

org.mockito.invocation.InvocationOnMock

when(client.deleteByQuery(anyString(), anyString())).then(invocationOnMock -> {
    assertEquals("myCollection", invocationOnMock.getArgument(0));
    assertThat(invocationOnMock.getArgument(1), Matchers.startsWith("id:"));
}

Use any of these

legend.spacing = unit(1,"cm")
legend.spacing.x = unit(1,"cm")
legend.spacing.y = unit(1,"cm")

Giving another answer, because my edits of other answers where rejected.

This is the most concise and simple answer (similar to Garret Hall's)

File("filename").writeAll("hello world")

This is similar to Jus12, but without the verbosity and with correct code style

def using[A <: {def close(): Unit}, B](resource: A)(f: A => B): B =
  try f(resource) finally resource.close()

def writeToFile(path: String, data: String): Unit = 
  using(new FileWriter(path))(_.write(data))

def appendToFile(path: String, data: String): Unit =
  using(new PrintWriter(new FileWriter(path, true)))(_.println(data))

Note you do NOT need the curly braces for try finally, nor lambdas, and note usage of placeholder syntax. Also note better naming.

This can be achieved using awk
Below Line will display unique Values

awk file_name | uniq

You can output these unique values to a new file

awk file_name | uniq > uniq_file_name

new file uniq_file_name will contain only Unique values, no duplicates

In XSLT the same <xsl:variable> can be declared only once and can be given a value only at its declaration. If more than one variables are declared at the same time, they are in fact different variables and have different scope.

Therefore, the way to achieve the wanted conditional setting of the variable and producing its value is the following:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes"/>

    <xsl:template match="class">
    <xsl:variable name="subexists">
            <xsl:choose>
                <xsl:when test="joined-subclass">true</xsl:when>
                <xsl:otherwise>false</xsl:otherwise>
            </xsl:choose>
        </xsl:variable>
        subexists:  <xsl:text/>    
        <xsl:value-of select="$subexists" />
    </xsl:template>
</xsl:stylesheet>

When the above transformation is applied on the following XML document:

<class>
 <joined-subclass/>
</class>

the wanted result is produced:

    subexists:  true

res.json eventually calls res.send, but before that it:

• respects the json spaces and json replacer app settings
• ensures the response will have utf8 charset and application/json content-type

You'll need to install (or enable) the Socket PHP extension: http://www.php.net/manual/en/sockets.installation.php

if(listAxu.size() > 0){
     Collections.sort(listAxu, new Comparator<Situacao>(){
        @Override

What worked for me was overriding the PATH environment for the slave.

Set:   PATH 
To:    $PATH:/usr/local/bin

Then disconnecting and reconnecting the slave.

Despite what the system information was showing it worked.

See: http://www.postgresql.org/docs/9.1/static/arrays.html

If your non-native driver still does not allow you to pass arrays, then you can:

• pass a string representation of an array (which your stored procedure can then parse into an array -- see string_to_array)

  CREATE FUNCTION my_method(TEXT) RETURNS VOID AS $$ 
  DECLARE
         ids INT[];
  BEGIN
         ids = string_to_array($1,',');
         ...
  END $$ LANGUAGE plpgsql;
  

  then

  SELECT my_method(:1)
  

  with :1 = '1,2,3,4'

• rely on Postgres itself to cast from a string to an array

  CREATE FUNCTION my_method(INT[]) RETURNS VOID AS $$ 
         ...
  END $$ LANGUAGE plpgsql;
  

  then

  SELECT my_method('{1,2,3,4}')
  

• choose not to use bind variables and issue an explicit command string with all parameters spelled out instead (make sure to validate or escape all parameters coming from outside to avoid SQL injection attacks.)

  CREATE FUNCTION my_method(INT[]) RETURNS VOID AS $$ 
         ...
  END $$ LANGUAGE plpgsql;
  

  then

  SELECT my_method(ARRAY [1,2,3,4])
  

1. Download file from this link
2. Extract it and move executable file(/wkhtmltox/bin/wkhtmltopdf) to /usr/bin/
3. Rename it to wkhtmltopdf if current name is not wkhtmltopdf. So that now you have an executable at /usr/bin/wkhtmltopdf
4. Set permissions: sudo chmod a+x /usr/bin/wkhtmltopdf
5. Install required support packages. sudo apt-get install openssl build-essential xorg libssl-dev
6. Now, check with wkhtmltopdf http://www.google.com test.pdf hint: detail information from this link

As per user667073 suggested, except reordering the backslash replacement first, and fixing the quote replacement

escape = function (str) {
  return str
    .replace(/[\\]/g, '\\\\')
    .replace(/[\"]/g, '\\\"')
    .replace(/[\/]/g, '\\/')
    .replace(/[\b]/g, '\\b')
    .replace(/[\f]/g, '\\f')
    .replace(/[\n]/g, '\\n')
    .replace(/[\r]/g, '\\r')
    .replace(/[\t]/g, '\\t');
};

The author of this post (now deleted post) suggests checking your C:\Windows\System32 folder to make sure that the oci.dll exists there. Copying in the file from the Oracle home directory solved this problem for me.

Which version of .NET are you using? If it's .NET 3.5, I'd just call ToArray() and be done with it.

If you only have a non-generic IEnumerable, do something like this:

IEnumerable query = ...;
MyEntityType[] array = query.Cast<MyEntityType>().ToArray();

If you don't know the type within that method but the method's callers do know it, make the method generic and try this:

public static void T[] PerformQuery<T>()
{
    IEnumerable query = ...;
    T[] array = query.Cast<T>().ToArray();
    return array;
}

You will have to use the fluent API to do this.

Try adding the following to your DbContext:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{   
    modelBuilder.Entity<User>()
        .HasOptional(a => a.UserDetail)
        .WithOptionalDependent()
        .WillCascadeOnDelete(true);
}

Always check for the obvious too. I got this error once when I accidently grabbed the wrong resource for the server's add and remove action. It can be easy to overlook.

The first column actually refers to Text Field:

  // Add the pet to our listview
    ListViewItem lvi = new ListViewItem();
    lvi.text = pet.Name;
    lvi.SubItems.Add(pet.Type);
    lvi.SubItems.Add(pet.Age);

    listView.Items.Add(lvi);

Or you can use the Constructor

 ListViewItem lvi = new ListViewItem(pet.Name);
 lvi.SubItems.Add(pet.Type);
 ....

Just a silly mistake use quote('') in '200px'

 <html>
  <head>    
  </head>

<body >
    <button type="button" onClick = "document.getElementById('chartdiv').style.height = '200px';">Click Me!</button>
    <div id="chartdiv" style="width: 100%; height: 50px; background-color:#E8EDF2"></div>
</body>

Indexing in python starting from 0. You wrote [1:] this would not return you a first char in any case - this will return you a rest(except first char) of string.

If you have the following structure:

mylist = ['base', 'sample', 'test']

And want to get fist char for the first one string(item):

myList[0][0]
>>> b

If all first chars:

[x[0] for x in myList]
>>> ['b', 's', 't']    

If you have a text:

text = 'base sample test'
text.split()[0][0]
>>> b

In ~/.subversion/config, you probably have store-passwords = no. Change it to yes (or just comment it out because it defaults to yes), and the next time you give Subversion your password it should save it.

You might want to ensure that the owner and permissions of ~/.subversion/config are correct (no public or group access; 600).

Actually I don't know what is the reason exactly, I have faced this like of problem. if you have the domain's IP address (ex 208.113.139.4), please use the IP address instead of domain (in this case www.icerts.com)

wget 192.243.111.11/images/logo.jpg

Go to find the IP from URL https://ipinfo.info/html/ip_checker.php

I solved my problem using this code, is a somewhat replacement for the missing splice.

let str = "I need to remove a character from this";
let pos = str.indexOf("character")

if(pos>-1){
  let result = str.slice(0, pos-2) + str.slice(pos, str.length);
  console.log(result) //I need to remove character from this 
}

I needed to remove a character before/after a certain word, after you get the position the string is split in two and then recomposed by flexibly removing characters using an offset along pos

I had this issue once. It turned out to be database query issue. After re-create tables and index it has been fixed.

Although it says proxy error, when you look at server log, it shows execute query timeout. This is what I had before and how I solved it.

it should work

example_string = '0, 0, 0, 11, 0, 0, 0, 0, 0, 19, 0, 9, 0, 0, 0, 0, 0, 0, 11'
example_list = [int(k) for k in example_string.split(',')]

You can use @Qualifier along with @Autowired. In fact spring will ask you explicitly select the bean if ambiguous bean type are found, in which case you should provide the qualifier

For Example in following case it is necessary provide a qualifier

@Component
@Qualifier("staff") 
public Staff implements Person {}

@Component
@Qualifier("employee") 
public Manager implements Person {}


@Component
public Payroll {

    private Person person;

    @Autowired
    public Payroll(@Qualifier("employee") Person person){
          this.person = person;
    }

}

EDIT:

In Lombok 1.18.4 it is finally possible to avoid the boilerplate on constructor injection when you have @Qualifier, so now it is possible to do the following:

@Component
@Qualifier("staff") 
public Staff implements Person {}

@Component
@Qualifier("employee") 
public Manager implements Person {}


@Component
@RequiredArgsConstructor
public Payroll {
   @Qualifier("employee") private final Person person;
}

provided you are using the new lombok.config rule copyableAnnotations (by placing the following in lombok.config in the root of your project):

# Copy the Qualifier annotation from the instance variables to the constructor
# see https://github.com/rzwitserloot/lombok/issues/745
lombok.copyableAnnotations += org.springframework.beans.factory.annotation.Qualifier

This was recently introduced in latest lombok 1.18.4.

• The blog post where the issue is discussed in detail
• The original issue on github
• And a small github project to see it in action

NOTE

If you are using field or setter injection then you have to place the @Autowired and @Qualifier on top of the field or setter function like below(any one of them will work)

public Payroll {
   @Autowired @Qualifier("employee") private final Person person;
}

or

public Payroll {
   private final Person person;
   @Autowired
   @Qualifier("employee")
   public void setPerson(Person person) {
     this.person = person;
   } 
}

If you are using constructor injection then the annotations should be placed on constructor, else the code would not work. Use it like below -

public Payroll {

    private Person person;

    @Autowired
    public Payroll(@Qualifier("employee") Person person){
          this.person = person;
    }

}

SOME_PATH=/mnt/someProject/some\ path

should work

SELECT NAME AS ObjectName
    ,schema_name(o.schema_id) AS SchemaName, OBJECT_NAME(o.parent_object_id) as TableName
    ,type
    ,o.type_desc
FROM sys.objects o
WHERE o.is_ms_shipped = 0
    AND o.NAME LIKE '%UniqueID%'
ORDER BY o.NAME

With EF Core in .NET Core you can use the keyword ThenInclude :

return DatabaseContext.Applications
 .Include(a => a.Children).ThenInclude(c => c.ChildRelationshipType);

Include childs from childrens collection :

return DatabaseContext.Applications
 .Include(a => a.Childrens).ThenInclude(cs => cs.ChildRelationshipType1)
 .Include(a => a.Childrens).ThenInclude(cs => cs.ChildRelationshipType2);

Tchoupi's answer can be made a tad less verbose by concatenating the argument for strtotime() as follows:

$effectiveDate = date('Y-m-d', strtotime($effectiveDate . "+3 months") );

(This relies on magic implementation details, but you can always go have a look at them if you're rightly mistrustful.)

That is because Low is a string.

.toFixed() only works with a number.

Try doing:

Low = parseFloat(Low).toFixed(..);

Just an update with Java Generics.

You could create an utility method to retrieve an optional value of any Java type from a given ResultSet, previously casted.

Unfortunately, getObject(columnName, Class) does not return null, but the default value for given Java type, so 2 calls are required

public <T> T getOptionalValue(final ResultSet rs, final String columnName, final Class<T> clazz) throws SQLException {
    final T value = rs.getObject(columnName, clazz);
    return rs.wasNull() ? null : value;
}

In this example, your code could look like below:

final Integer columnValue = getOptionalValue(rs, Integer.class);
if (columnValue == null) {
    //null handling
} else {
    //use int value of columnValue with autoboxing
}

Happy to get feedback

Working solution:

Bootstrap 3.0 by default has a 15px padding on top and bottom, so we just need to override it!

For example:

.navbar-nav > li > a {padding-top:10px !important; padding-bottom:10px !important;}
.navbar {min-height:40px !important}

you can try in this way if you are using thymeleaf

sec:authorize="hasAnyRole(T(com.orsbv.hcs.model.SystemRole).ADMIN.getName(),
               T(com.orsbv.hcs.model.SystemRole).SUPER_USER.getName(),'ROLE_MANAGEMENT')"

this will return true if the user has the mentioned roles,false otherwise.

Please note you have to use sec tag in your html declaration tag like this

<html xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">

Why the value had to be given in yyyy-MM-dd?

According to the input type = date spec of HTML 5, the value has to be in the format yyyy-MM-dd since it takes the format of a valid full-date which is specified in RFC3339 as

full-date = date-fullyear "-" date-month "-" date-mday

There is nothing to do with Angularjs since the directive input doesn't support date type.

How do I get Firefox to accept my formatted value in the date input?

FF doesn't support date type of input for at least up to the version 24.0. You can get this info from here. So for right now, if you use input with type being date in FF, the text box takes whatever value you pass in.

My suggestion is you can use Angular-ui's Timepicker and don't use the HTML5 support for the date input.

I can't comment on ars's answer, but I actually got Roland Tapken's code running using QtWebkit and it works quite well.

Just wanted to confirm that what Roland posts on his blog works great on Ubuntu. Our production version ended up not using any of what he wrote but we are using the PyQt/QtWebKit bindings with much success.

Note: The URL used to be: http://www.blogs.uni-osnabrueck.de/rotapken/2008/12/03/create-screenshots-of-a-web-page-using-python-and-qtwebkit/ I've updated it with a working copy.

That has happened for me when using externals and one of them was corrupt. I had to go to that folder and perform a cleanup. Then the cleanup worked for the entire working copy.

Example: Using external ^/widgets/foo common/foo-widget, first perform cleanup on folder common/foo-widget.

The repository is not down, it looks like they've changed how they host files (I guess they have restored some old code):

Now you have to add the /package-name/ before the -

Eg:

http://registry.npmjs.org/-/npm-1.1.48.tgz
http://registry.npmjs.org/npm/-/npm-1.1.48.tgz

There are 3 ways to solve it:

• Use a complete mirror:

• Use a public proxy:

  --registry http://165.225.128.50:8000

• Host a local proxy:

  https://github.com/hughsk/npm-quickfix

git clone https://github.com/hughsk/npm-quickfix.git
cd npm-quickfix
npm set registry http://localhost:8080/
node index.js

I'd personally go with number 3 and revert to npm set registry http://registry.npmjs.org/ as soon as this get resolved.

Stay tuned here for more info: https://github.com/isaacs/npm/issues/2694

You can do:

$("#submittername").text("testing");

or

VMDK is a virtual disk file, what you need is a VMX file. Cruise on over to EasyVMX and have it create one for you, then just replace the VMDK file it gives you with the Cnrome OS one.

EasyVMX is good since VMWare Player has no VM creation stuff in it (at least in version 2, not sure about 3). You had to use one of VMWare's other products to do that.

I used custom DTO (interface) to map a native query to - the most flexible approach and refactoring-safe.

The problem I had with this - that surprisingly, the order of fields in the interface and the columns in the query matters. I got it working by ordering interface getters alphabetically and then ordering the columns in the query the same way.

Jarrett's answer creates a new table.

Scott's answer inserts into an existing table with the same structure.

You can also insert into a table with different structure:

INSERT Table2
(columnX, columnY)
SELECT column1, column2 FROM Table1
WHERE [Conditions]

Here is my working example:

[HttpPost]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Create(Product product, HttpPostedFileBase file)
    {
        if (!ModelState.IsValid)
            return PartialView("Create", product);
        if (file != null)
        {

            var fileName = Path.GetFileName(file.FileName);
            var guid = Guid.NewGuid().ToString();
            var path = Path.Combine(Server.MapPath("~/Content/Uploads/ProductImages"), guid + fileName);
            file.SaveAs(path);
            string fl = path.Substring(path.LastIndexOf("\\"));
            string[] split = fl.Split('\\');
            string newpath = split[1];
            string imagepath = "Content/Uploads/ProductImages/" + newpath;
            using (MemoryStream ms = new MemoryStream())
            {
                file.InputStream.CopyTo(ms);
                byte[] array = ms.GetBuffer();
            }
            var nId = Guid.NewGuid().ToString();
            // Save record to database
            product.Id = nId;
            product.State = 1;
            product.ImagePath = imagepath;
            product.CreatedAt = DateTime.Now;
            db.Products.Add(product);
            await db.SaveChangesAsync();
            TempData["message"] = "ProductCreated";

            //return RedirectToAction("Index", product);
        }
        // after successfully uploading redirect the user
        return Json(new { success = true });
    }

string is an alias (or shorthand) of System.String. That means, by typing string we meant System.String. You can read more in think link: 'string' is an alias/shorthand of System.String.

I'm not interested in outputting it to the screen (that's what printf is mainly used for, right?) The variable $num is going to be used as a parameter for another program but let me see what I can do with this.

You can still use printf:

for num in {1..5}
do
   value=$(printf "%02d" $num)
   ... Use $value for your purposes
done

This will apply to any form. No need of scrollview. do not forget to set delegate.

Make a var of uitextfield

var clickedTextField = UITextField()

In your viewdid load

NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name:NSNotification.Name.UIKeyboardWillShow, object: nil);
NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name:NSNotification.Name.UIKeyboardWillHide, object: nil);

Know the clicked text field. probably you are having textfields on the entire screen.

func textFieldDidBeginEditing(_ textField: UITextField) {
    clickedTextField = textField
}

Check if the keyboard is covering textfield or not.

@objc func keyboardWillShow(sender: NSNotification,_ textField : UITextField) {
    if let keyboardSize = (sender.userInfo?[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {

        if clickedTextField.frame.origin.y > keyboardSize.origin.y {
            self.view.frame.origin.y = keyboardSize.origin.y - clickedTextField.center.y - 20
        }
    }
}

@objc func keyboardWillHide(sender: NSNotification) {
    self.view.frame.origin.y = 0
}

Return to close keyboard

func textFieldShouldReturn(_ textField: UITextField) -> Bool {   //delegate method
    textField.resignFirstResponder()
    return true
}

UPDATE : NSNotification.Name.UIKeyboardWillShow & NSNotification.Name.UIKeyboardWillHide are renamed to UIResponder.keyboardWillShowNotification & UIResponder.keyboardWillHideNotification respectively.

This block of code makes a path of your app directory in string type

string path="";
path=System.AppContext.BaseDirectory;

good luck

You can use the function outer() to generate it.

Have a look at the demo for the function persp(), which is a base graphics function to draw perspective plots for surfaces.

Here is their first example:

x <- seq(-10, 10, length.out = 50)  
y <- x  
rotsinc <- function(x,y) {
    sinc <- function(x) { y <- sin(x)/x ; y[is.na(y)] <- 1; y }  
    10 * sinc( sqrt(x^2+y^2) )  
}

z <- outer(x, y, rotsinc)  
persp(x, y, z)

The same applies to surface3d():

require(rgl)  
surface3d(x, y, z)

To support IE11 with auto-placement, I converted grid to table layout every time I used the grid layout in 1 dimension only. I also used margin instead of grid-gap.

The result is the same, see how you can do it here https://jsfiddle.net/hp95z6v1/3/

Had same issue this end of week, only Firefox will not accept certificate... The solution for me has been to add, in the apache configuration of the website, the intermediate certificate with the following line :

SSLCACertificateFile /your/path/to/ssl_ca_certs.pem

Find more infomration on https://httpd.apache.org/docs/2.4/fr/mod/mod_ssl.html

Check that C:\Program Files (x86)\Git\cmd is in you Path environment variable:

echo $env:Path

Essentially, and as-noted by @kevin-b:

// find('#id')
angular.element(document.querySelector('#id'))

//find('.classname'), assumes you already have the starting elem to search from
angular.element(elem.querySelector('.classname'))

Note: If you're looking to do this from your controllers you may want to have a look at the "Using Controllers Correctly" section in the developers guide and refactor your presentation logic into appropriate directives (such as <a2b ...>).

void pointer is a generic pointer.. Address of any datatype of any variable can be assigned to a void pointer.

int a = 10;
float b = 3.14;
void *ptr;
ptr = &a;
printf( "data is %d " , *((int *)ptr)); 
//(int *)ptr used for typecasting dereferencing as int
ptr = &b;
printf( "data is %f " , *((float *)ptr));
//(float *)ptr used for typecasting dereferencing as float

I face this problem 5 minutes before.

I think that a solution (with visual studio 2005) is:

myString = comboBoxTest.GetItemText(comboBoxTest.SelectedItem);

Forgive me if I am wrong.

You can also use AWK which can give you more flexibility to handle the file

awk '{ print "chmod 755 "$0"" | "/bin/sh"}' file.txt

if your file has a field separator like:

field1,field2,field3

To get only the first field you do

awk -F, '{ print "chmod 755 "$1"" | "/bin/sh"}' file.txt

You can check more details on GNU Documentation https://www.gnu.org/software/gawk/manual/html_node/Very-Simple.html#Very-Simple

You might also try giving the full path to the binary you're trying to run. That solved my problem when trying to use ImageMagick.

You had it nearly right in the last line. You want

str(bytes_string, 'utf-8')

because the type of bytes_string is bytes, the same as the type of b'abc'.

I had a similar problem recently and found out, that client_max_body_size 0; can solve such an issue. This will set client_max_body_size to no limit. But the best practice is to improve your code, so there is no need to increase this limit.

The best way depends a lot on the platform(s) being targeted, debug vs. release usage etc.

I don't think there is one best way, but to "force" a wait on enter type scenario in a fairly generic way, especially when debugging (typically this is either compiled in or out based on NDEBUG or _DEBUG), you could try std::getline as follows

inline void wait_on_enter()
{
    std::string dummy;
    std::cout << "Enter to continue..." << std::endl;
    std::getline(std::cin, dummy);
}

With our without the "enter to continue", as needed.

I tried all of the above solutions and it still wouldn't work, until I found that the web.config compilation element was referencing version 2.0.0.0 of WebMatrix.Data and WebMatrix.WebData. Changing the version of those entries in the web.config to 3.0.0.0 helped me.

You need a ResourceLink in your META-INF/context.xml file to make the global resource available to the web application.

It seems like it exists a bug in jQuery reported here : http://bugs.jquery.com/ticket/13183 that breaks the Fancybox script.

Also check https://github.com/fancyapps/fancyBox/issues/485 for further reference.

As a workaround, rollback to jQuery v1.8.3 while either the jQuery bug is fixed or Fancybox is patched.

UPDATE (Jan 16, 2013): Fancybox v2.1.4 has been released and now it works fine with jQuery v1.9.0.

For fancybox v1.3.4- you still need to rollback to jQuery v1.8.3 or apply the migration script as pointed out by @Manu's answer.

UPDATE (Jan 17, 2013): Workaround for users of Fancybox v1.3.4 :

Patch the fancybox js file to make it work with jQuery v1.9.0 as follow :

1. Open the jquery.fancybox-1.3.4.js file (full version, not pack version) with a text/html editor.

2. Find around the line 29 where it says :

   isIE6 = $.browser.msie && $.browser.version < 7 && !window.XMLHttpRequest,
   

   and replace it by (EDITED March 19, 2013: more accurate filter):

   isIE6 = navigator.userAgent.match(/msie [6]/i) && !window.XMLHttpRequest,
   

   UPDATE (March 19, 2013): Also replace $.browser.msie by navigator.userAgent.match(/msie [6]/i) around line 615 (and/or replace all $.browser.msie instances, if any), thanks joofow ... that's it!

Or download the already patched version from HERE (UPDATED March 19, 2013 ... thanks fairylee for pointing out the extra closing bracket)

NOTE: this is an unofficial patch and is unsupported by Fancybox's author, however it works as is. You may use it at your own risk ;)

Optionally, you may rather rollback to jQuery v1.8.3 or apply the migration script as pointed out by @Manu's answer.

From Mac OS Catalina .bash_profile is replaced with .zprofile

Step 1: Create a .zprofile

touch .zprofile

Step 2:

nano .zprofile

type below line in this

source ~/.bash_profile

and save(ctrl+o return ctrl+x)

Step 3: Restart your terminal

To Add Git Branch Name Now you can add below lines in .bash_profile

    parse_git_branch() {
    git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}

export PS1="\u@\h \[\033[32m\]\w - \$(parse_git_branch)\[\033[00m\] $ "

Restart your terminal this will work.

Note: Even you can rename .bash_profile to .zprofile that also works.

Also be careful how you execute the js on the page. For example if you do something like this:

(function(window, document, undefined){

  var foo = document.getElementById("foo");

  console.log(foo);

})(window, document, undefined); 

This will return null because you'd be calling the document before it was loaded.

Better option..

(function(window, document, undefined){

// code that should be taken care of right away

window.onload = init;

  function init(){
    // the code to be called when the dom has loaded
    // #document has its nodes
  }

})(window, document, undefined);

in rare cases when you can't use strncat, strcat or strcpy. And you don't have access to <string.h> so you can't use strlen. Also you maybe don't even know the size of the char arrays and you still want to concatenate because you got only pointers. Well, you can do old school malloc and count characters yourself like..

char *combineStrings(char* inputA, char* inputB) {
    size_t len = 0, lenB = 0;
    while(inputA[len] != '\0') len++;
    while(inputB[lenB] != '\0') lenB++;
    char* output = malloc(len+lenB);
    sprintf((char*)output,"%s%s",inputA,inputB);
    return output;
}

It just needs #include <stdio.h> which you will have most likely included already

textField.layer.borderWidth = 3;

will add border, which worked as padding for me.

I Know this question was aked 3 years ago, but I just had the same problem, and what solved it was instead of putting:

 while (i.hasNext()) {
    // code goes here 
}

I did one iteration at the start, and then checked for condition using:

do {
   // code goes here
} while (i.hasNext());

I hope this will help some people at some stage.

Register an out parameter for the stored procedure, and set the value based on @@ROWCOUNT if using SQL Server. Use SQL%ROWCOUNT if you are using Oracle.

Mind that if you have multiple INSERT/UPDATE/DELETE, you'll need a variable to store the result from @@ROWCOUNT for each operation.

I have encountered the exception java.lang.IllegalArgumentException: Unknown URI: content://downloads/public_downloads/7505 in getting the doucument from the downloads. This solution worked for me.

else if (isDownloadsDocument(uri)) {
            String fileName = getFilePath(context, uri);
            if (fileName != null) {
                return Environment.getExternalStorageDirectory().toString() + "/Download/" + fileName;
            }

            String id = DocumentsContract.getDocumentId(uri);
            if (id.startsWith("raw:")) {
                id = id.replaceFirst("raw:", "");
                File file = new File(id);
                if (file.exists())
                    return id;
            }

            final Uri contentUri = ContentUris.withAppendedId(Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
            return getDataColumn(context, contentUri, null, null);
        }

This the method used to get the filepath

   public static String getFilePath(Context context, Uri uri) {

    Cursor cursor = null;
    final String[] projection = {
            MediaStore.MediaColumns.DISPLAY_NAME
    };

    try {
        cursor = context.getContentResolver().query(uri, projection, null, null,
                null);
        if (cursor != null && cursor.moveToFirst()) {
            final int index = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DISPLAY_NAME);
            return cursor.getString(index);
        }
    } finally {
        if (cursor != null)
            cursor.close();
    }
    return null;
}

Since you are providing a relative pathway to the image, the image location is looked for from the location in which you have the css file. So if you have the image in a different location to the css file you could either try giving the absolute URL(pathway starting from the root folder) or give the relative file location path. In your case since img and css are in the folder assets to move from location of css file to the img file, you can use '..' operator to refer that the browser has to move 1 folder back and then follow the pathway you have after the '..' operator. This is basically how relative pathway works and you can use it to access resoures in different folders. Hope it helps.

You are passing a dictionary to a function that expects a string.

This syntax:

{"('Hello',)": 6, "('Hi',)": 5}

is both a valid Python dictionary literal and a valid JSON object literal. But loads doesn't take a dictionary; it takes a string, which it then interprets as JSON and returns the result as a dictionary (or string or array or number, depending on the JSON, but usually a dictionary).

If you pass this string to loads:

'''{"('Hello',)": 6, "('Hi',)": 5}'''

then it will return a dictionary that looks a lot like the one you are trying to pass to it.

You could also exploit the similarity of JSON object literals to Python dictionary literals by doing this:

json.loads(str({"('Hello',)": 6, "('Hi',)": 5}))

But in either case you would just get back the dictionary that you're passing in, so I'm not sure what it would accomplish. What's your goal?

If you want to set null value using update query set column value to NULL (without quotes) update tablename set columnname = NULL

However, if you are directly editing field value inside mysql workbench then use (Esc + del) keystroke to insert null value into selected column

Copying Will's comment into an answer, because I found it useful:

var string = "this is a string";
var length = 20;
var trimmedString = string.length > length ? 
                    string.substring(0, length - 3) + "..." : 
                    string;

Thanks Will.

You need to set Div2 to Div1's innerHTML. Also, JavaScript is case sensitive - in your HTML, the id Div2 is DIV2. Also, you should use document, not Document:

var MyDiv2 = document.getElementById('DIV2');
MyDiv2.innerHTML = MyDiv1.innerHTML;

For a long time, DOM3 mutation events were the best available solution, but they have been deprecated for performance reasons. DOM4 Mutation Observers are the replacement for deprecated DOM3 mutation events. They are currently implemented in modern browsers as MutationObserver (or as the vendor-prefixed WebKitMutationObserver in old versions of Chrome):

MutationObserver = window.MutationObserver || window.WebKitMutationObserver;

var observer = new MutationObserver(function(mutations, observer) {
    // fired when a mutation occurs
    console.log(mutations, observer);
    // ...
});

// define what element should be observed by the observer
// and what types of mutations trigger the callback
observer.observe(document, {
  subtree: true,
  attributes: true
  //...
});

This example listens for DOM changes on document and its entire subtree, and it will fire on changes to element attributes as well as structural changes. The draft spec has a full list of valid mutation listener properties:

childList

• Set to true if mutations to target's children are to be observed.

attributes

• Set to true if mutations to target's attributes are to be observed.

characterData

• Set to true if mutations to target's data are to be observed.

subtree

• Set to true if mutations to not just target, but also target's descendants are to be observed.

attributeOldValue

• Set to true if attributes is set to true and target's attribute value before the mutation needs to be recorded.

characterDataOldValue

• Set to true if characterData is set to true and target's data before the mutation needs to be recorded.

attributeFilter

• Set to a list of attribute local names (without namespace) if not all attribute mutations need to be observed.

(This list is current as of April 2014; you may check the specification for any changes.)

I ran into a similar issue with getting SSL to work on a port other than port 443. In my case I had a bundle certificate as well as a certificate and a key. The bundle certificate is a file that holds multiple certificates, node requires that you break those certificates into separate elements of an array.

    var express = require('express');
    var https = require('https');
    var fs = require('fs');

    var options = {
      ca: [fs.readFileSync(PATH_TO_BUNDLE_CERT_1), fs.readFileSync(PATH_TO_BUNDLE_CERT_2)],
      cert: fs.readFileSync(PATH_TO_CERT),
      key: fs.readFileSync(PATH_TO_KEY)
    };

    app = express()

    app.get('/', function(req,res) {
        res.send('hello');
    });

    var server = https.createServer(options, app);

    server.listen(8001, function(){
        console.log("server running at https://IP_ADDRESS:8001/")
    });

In app.js you need to specify https and create the server accordingly. Also, make sure that the port you're trying to use is actually allowing inbound traffic.

an even simpler solution tested with version 5.2

in your model

// validator rules
public static $rules = array(
    ...
    'email_address' => 'email|required|unique:users,id'
);

This should work perfectly for string (or single character) delimiters. Don't forget to include #include <sstream>.

std::string input = "Alfa=,+Bravo=,+Charlie=,+Delta";
std::string delimiter = "=,+"; 
std::istringstream ss(input);
std::string token;
std::string::iterator it;

while(std::getline(ss, token, *(it = delimiter.begin()))) {
    std::cout << token << " " << '\n'; // Token is extracted using '='
    while(*(++it)) ss.get();           // Skip the rest of delimiter if exists ",+"
}

The first while loop extracts a token using the first character of the string delimiter. The second while loop skips the rest of the delimiter and stops at the beginning of the next token.

Why I can't initialize static data members in class?

The C++ standard allows only static constant integral or enumeration types to be initialized inside the class. This is the reason a is allowed to be initialized while others are not.

Reference:
C++03 9.4.2 Static data members
§4

If a static data member is of const integral or const enumeration type, its declaration in the class definition can specify a constant-initializer which shall be an integral constant expression (5.19). In that case, the member can appear in integral constant expressions. The member shall still be defined in a namespace scope if it is used in the program and the namespace scope definition shall not contain an initializer.

What are integral types?

C++03 3.9.1 Fundamental types
§7

Types bool, char, wchar_t, and the signed and unsigned integer types are collectively called integral types.43) A synonym for integral type is integer type.

Footnote:

⁴³⁾ Therefore, enumerations (7.2) are not integral; however, enumerations can be promoted to int, unsigned int, long, or unsigned long, as specified in 4.5.

Workaround:

You could use the enum trick to initialize an array inside your class definition.

class A 
{
    static const int a = 3;
    enum { arrsize = 2 };

    static const int c[arrsize] = { 1, 2 };

};

Why does the Standard does not allow this?

Bjarne explains this aptly here:

A class is typically declared in a header file and a header file is typically included into many translation units. However, to avoid complicated linker rules, C++ requires that every object has a unique definition. That rule would be broken if C++ allowed in-class definition of entities that needed to be stored in memory as objects.

Why are only static const integral types & enums allowed In-class Initialization?

The answer is hidden in Bjarne's quote read it closely,
"C++ requires that every object has a unique definition. That rule would be broken if C++ allowed in-class definition of entities that needed to be stored in memory as objects."

Note that only static const integers can be treated as compile time constants. The compiler knows that the integer value will not change anytime and hence it can apply its own magic and apply optimizations, the compiler simply inlines such class members i.e, they are not stored in memory anymore, As the need of being stored in memory is removed, it gives such variables the exception to rule mentioned by Bjarne.

It is noteworthy to note here that even if static const integral values can have In-Class Initialization, taking address of such variables is not allowed. One can take the address of a static member if (and only if) it has an out-of-class definition.This further validates the reasoning above.

enums are allowed this because values of an enumerated type can be used where ints are expected.^{see citation above}

How does this change in C++11?

C++11 relaxes the restriction to certain extent.

C++11 9.4.2 Static data members
§3

If a static data member is of const literal type, its declaration in the class definition can specify a brace-or-equal-initializer in which every initializer-clause that is an assignment-expression is a constant expression. A static data member of literal type can be declared in the class definition with the constexpr specifier; if so, its declaration shall specify a brace-or-equal-initializer in which every initializer-clause that is an assignment-expression is a constant expression. [ Note: In both these cases, the member may appear in constant expressions. —end note ] The member shall still be defined in a namespace scope if it is used in the program and the namespace scope definition shall not contain an initializer.

Also, C++11 will allow(§12.6.2.8) a non-static data member to be initialized where it is declared(in its class). This will mean much easy user semantics.

Note that these features have not yet been implemented in latest gcc 4.7, So you might still get compilation errors.

If you don't need much in the way of custom behavior, JOptionPane is a good time saver. It takes care of the placement and localization of OK / Cancel options, and is a quick-and-dirty way to show a custom dialog without needing to define your own classes. Most of the time the "message" parameter in JOptionPane is a String, but you can pass in a JComponent or array of JComponents as well.

Example:

JTextField firstName = new JTextField();
JTextField lastName = new JTextField();
JPasswordField password = new JPasswordField();
final JComponent[] inputs = new JComponent[] {
        new JLabel("First"),
        firstName,
        new JLabel("Last"),
        lastName,
        new JLabel("Password"),
        password
};
int result = JOptionPane.showConfirmDialog(null, inputs, "My custom dialog", JOptionPane.PLAIN_MESSAGE);
if (result == JOptionPane.OK_OPTION) {
    System.out.println("You entered " +
            firstName.getText() + ", " +
            lastName.getText() + ", " +
            password.getText());
} else {
    System.out.println("User canceled / closed the dialog, result = " + result);
}

Models.py define the serializers

       return json.loads(json.dumps(dict_val,default=default))

In RestApi, We can update the record dynamically by passing the json data into update query:

      user_id = current_user.id
      try:
         instance = User.query.filter(User.id==user_id)
         data=instance.update(dict(json_data))
         db.session.commit()
         updateddata=instance.first()
         msg={"msg":"User details updated successfully","data":updateddata.serializers()}
         code=200
      except Exception as e:
         print(e)
         msg = {"msg": "Failed to update the userdetails! please contact your administartor."}
         code=500

Setting or Updating of Reactive Forms Form Control values can be done using both patchValue and setValue. However, it might be better to use patchValue in some instances.

patchValue does not require all controls to be specified within the parameters in order to update/set the value of your Form Controls. On the other hand, setValue requires all Form Control values to be filled in, and it will return an error if any of your controls are not specified within the parameter.

In this scenario, we will want to use patchValue, since we are only updating user and questioning:

this.qService.editQue([params["id"]]).subscribe(res => {
  this.question = res;
  this.editqueForm.patchValue({
    user: this.question.user,
    questioning: this.question.questioning
  });
});

EDIT: If you feel like doing some of ES6's Object Destructuring, you may be interested to do this instead

const { user, questioning } = this.question;

this.editqueForm.patchValue({
  user,
  questioning
});

Ta-dah!

That subroutine searches for some string and returns a collections of cells fullfilling your search criteria. Then you can do whatever you want with the cells in that collection. Forgot to add the FindAll function definition:

' FindAll
' This searches the range specified by SearchRange and returns a Range object
' that contains all the cells in which FindWhat was found. The search parameters to
' this function have the same meaning and effect as they do with the
' Range.Find method. If the value was not found, the function return Nothing. If
' BeginsWith is not an empty string, only those cells that begin with BeginWith
' are included in the result. If EndsWith is not an empty string, only those cells
' that end with EndsWith are included in the result. Note that if a cell contains
' a single word that matches either BeginsWith or EndsWith, it is included in the
' result.  If BeginsWith or EndsWith is not an empty string, the LookAt parameter
' is automatically changed to xlPart. The tests for BeginsWith and EndsWith may be
' case-sensitive by setting BeginEndCompare to vbBinaryCompare. For case-insensitive
' comparisons, set BeginEndCompare to vbTextCompare. If this parameter is omitted,
' it defaults to vbTextCompare. The comparisons for BeginsWith and EndsWith are
' in an OR relationship. That is, if both BeginsWith and EndsWith are provided,
' a match if found if the text begins with BeginsWith OR the text ends with EndsWith.

A small addition to the excellent answers given: If you're running with a non-ajax backup solution for users without javascript, you will have to get those server-side headers correct anyway. This is not impossible, although I understand those that give it up ;)

I'm sure there's another question on SO that will give you the full set of headers that are appropriate. I am not entirely conviced miceus reply covers all the bases 100%.

There's a difference between additive colors (http://en.wikipedia.org/wiki/Additive_color) and subtractive colors (http://en.wikipedia.org/wiki/Subtractive_color).

With additive colors, the more you add, the brighter the colors become. This is because they are emitting light. This is why the day light is (more or less) white, since the Sun is emitting in almost all the visible wavelength spectrum.

On the other hand, with subtractive colors the more colors you mix, the darker the resulting color. This is because they are reflecting light. This is also why the black colors get hotter quickly, because it absorbs (almost) all light energy and reflects (almost) none.

Specifically to your question, it depends what medium you are working on. Traditionally, additive colors (RGB) are used because the canon for computer graphics was the computer monitor, and since it's emitting light, it makes sense to use the same structure for the graphic card (the colors are shown without conversions). However, if you are used to graphic arts and press, subtractive color model is used (CMYK). In programs such as Photoshop, you can choose to work in CMYK space although it doesn't matter what color model you use: the primary colors of one group are the secondary colors of the second one and viceversa.

P.D.: my father worked at graphic arts, this is why i know this... :-P

Starting in MongoDB 3.4, you can use the $sortByCount aggregation.

Groups incoming documents based on the value of a specified expression, then computes the count of documents in each distinct group.

https://docs.mongodb.com/manual/reference/operator/aggregation/sortByCount/

For example:

db.contest.aggregate([
    { $sortByCount: "$province" }
]);

I think that it depends on your project complexity since angular is pretty much modularized. Your controllers can be mapped and you can just import those JavaScript classes in your index.html page.

But in case your project get bigger. Or you anticipates such scenario, you should integrate angular with requirejs. In this article you can see a demo app for such integration.

Here is an example

private void doOpenFile() {
    int result = myFileChooser.showOpenDialog(this);

    if (result == JFileChooser.APPROVE_OPTION) {
        Path path = myFileChooser.getSelectedFile().toPath();

        try {
            String contentString = "";

            for (String s : Files.readAllLines(path, StandardCharsets.UTF_8)) {
                contentString += s;
            }

            jText.setText(contentString);

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

private void doSaveFile() {
    int result = myFileChooser.showSaveDialog(this);

    if (result == JFileChooser.APPROVE_OPTION) {
        // We'll be making a mytmp.txt file, write in there, then move it to
        // the selected
        // file. This takes care of clearing that file, should there be
        // content in it.
        File targetFile = myFileChooser.getSelectedFile();

        try {
            if (!targetFile.exists()) {
                targetFile.createNewFile();
            }

            FileWriter fw = new FileWriter(targetFile);

            fw.write(jText.getText());
            fw.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

I would suggest to end java.exe or javaw.exe process from task manager and try again. This will not end the entire eclipse application but will free the port.

As discussed in the comments you have based your code on this solution: https://stackoverflow.com/a/8825714/681807

One of the key parts of this solution is to add height: 100% to html, body so the #footer element has a base height to work from - this is missing from your code:

html,body{
    height: 100%
}

You will also find that you will run into problems with using bottom: -50px as this will push your content under the fold when there isn't much content. You will have to add margin-bottom: 50px to the last element before the #footer.

if it is a RSA key

openssl rsa  -pubout -in my_rsa_key.pem

if you need it in a format for openssh , please see Use RSA private key to generate public key?

Note that public key is generated from the private key and ssh uses the identity file (private key file) to generate and send public key to server and un-encrypt the encrypted token from the server via the private key in identity file.

You don't need the assignment, list.append(x) will always append x to a and therefore there's no need te redefine a.

a = []
for i in range(5):    
    a.append(i)
print(a)

is all you need. This works because lists are mutable.

Also see the docs on data structures.

Gold plated edition of the above (I need a generic function which can infer a Window within the context of a MarkupExtension:-

public sealed class MyExtension : MarkupExtension
{
    public override object ProvideValue(IServiceProvider serviceProvider) =>
        new MyWrapper(ResolveRootObject(serviceProvider));
    object ResolveRootObject(IServiceProvider serviceProvider) => 
         GetService<IRootObjectProvider>(serviceProvider).RootObject;
}

class MyWrapper
{
    object _rootObject;

    Window OwnerWindow() => WindowFromRootObject(_rootObject);

    static Window WindowFromRootObject(object root) =>
        (root as Window) ?? VisualParent<Window>((DependencyObject)root);
    static T VisualParent<T>(DependencyObject node) where T : class
    {
        if (node == null)
            throw new InvalidOperationException("Could not locate a parent " + typeof(T).Name);
        var target = node as T;
        if (target != null)
            return target;
        return VisualParent<T>(VisualTreeHelper.GetParent(node));
    }
}

MyWrapper.Owner() will correctly infer a Window on the following basis:

• the root Window by walking the visual tree (if used in the context of a UserControl)
• the window within which it is used (if it is used in the context of a Window's markup)

The only solution is to use less data in your Unique Index. Your key can be NVARCHAR(450) at most.

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.

There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.

I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException and Application.ThreadException, as appropriate.

My implementation:

import math
n = 100
marked = {}
for i in range(2, int(math.sqrt(n))):
    if not marked.get(i):
        for x in range(i * i, n, i):
            marked[x] = True

for i in range(2, n):
    if not marked.get(i):
        print i

Change to:

SELECT 
  CASE 
    WHEN FRUIT = 'A' THEN 'APPLE' 
    WHEN FRUIT = 'B' THEN 'BANANA'     
  END
FROM FRUIT_TABLE;

Assume the following code:

import torch
import numpy as np
a = torch.tensor([1, 2, 3, 4, 5])

The following three calls have the exact same effect:

res_1 = a.unsqueeze(0)
res_2 = a.view(1, 5)
res_3 = a[np.newaxis,:]
res_1.shape == res_2.shape == res_3.shape == (1,5)  # Returns true

Notice that for any of the resulting tensors, if you modify the data in them, you are also modifying the data in a, because they don't have a copy of the data, but reference the original data in a.

res_1[0,0] = 2
a[0] == res_1[0,0] == 2  # Returns true

The other way of doing it would be using the resize_ in place operation:

a.shape == res_1.shape  # Returns false
a.reshape_((1, 5))
a.shape == res_1.shape # Returns true

Be careful of using resize_ or other in-place operation with autograd. See the following discussion: https://pytorch.org/docs/stable/notes/autograd.html#in-place-operations-with-autograd

Try this:

let utcTime = "2017-02-02 08:00:13";

var local_date= moment.utc(utcTime ).local().format('YYYY-MM-DD HH:mm:ss');

I think the best equivalent to PHP's var_dump($foo, $bar) is combine print with vars:

print vars(foo),vars(bar)

This polyfill code working in modern (2017) browsers (IE11, Opera, Chrome, FireFox, Yandex):

printStackTrace: function () {
    var err = new Error();
    var stack = err.stack || /*old opera*/ err.stacktrace || ( /*IE11*/ console.trace ? console.trace() : "no stack info");
    return stack;
}

Other answers:

function stackTrace() {
  var err = new Error();
  return err.stack;
}

not working in IE 11 !
