There are many ways to get jQuery AJAX response. I am sharing with you two common approaches:

First:

use async=false and within function return ajax-object and later get response ajax-object.responseText

/**
 * jQuery ajax method with async = false, to return response
 * @param  {mix}  selector - your selector
 * @return {mix}           - your ajax response/error
 */
function isSession(selector) {
    return $.ajax({
        type: "POST",
        url: '/order.html',
        data: {
            issession: 1,
            selector: selector
        },
        dataType: "html",
        async: !1,
        error: function() {
            alert("Error occured")
        }
    });
}
// global param
var selector = !0;
// get return ajax object
var ajaxObj = isSession(selector);
// store ajax response in var
var ajaxResponse = ajaxObj.responseText;
// check ajax response
console.log(ajaxResponse);
// your ajax callback function for success
ajaxObj.success(function(response) {
    alert(response);
});

Second:

use $.extend method and make a new function like ajax

/**
 * xResponse function
 *
 * xResponse method is made to return jQuery ajax response
 * 
 * @param  {string} url   [your url or file]
 * @param  {object} your ajax param
 * @return {mix}       [ajax response]
 */
$.extend({
    xResponse: function(url, data) {
        // local var
        var theResponse = null;
        // jQuery ajax
        $.ajax({
            url: url,
            type: 'POST',
            data: data,
            dataType: "html",
            async: false,
            success: function(respText) {
                theResponse = respText;
            }
        });
        // Return the response text
        return theResponse;
    }
});

// set ajax response in var
var xData = $.xResponse('temp.html', {issession: 1,selector: true});

// see response in console
console.log(xData);

you can make it as large as you want...

Use atof() or strtof()* instead:

printf("float value : %4.8f\n" ,atof(s)); 
printf("float value : %4.8f\n" ,strtof(s, NULL)); 

http://www.cplusplus.com/reference/clibrary/cstdlib/atof/
http://www.cplusplus.com/reference/cstdlib/strtof/

• atoll() is meant for integers.
• atof()/strtof() is for floats.

The reason why you only get 4.00 with atoll() is because it stops parsing when it finds the first non-digit.

*Note that strtof() requires C99 or C++11.

Span is an inline element. It has no width or height.

You could turn it into a block-level element, then it will accept your dimension directives.

span.product__specfield_8_arrow
{
    display: inline-block; /* or block */
}

Simply declare your variable to final

I feel cls is the best answer. It hides the UNC message before anyone can see it. I combined it with a @pushd %~dp0 right after so that it would seem like opening the script and map the location in one step, thus preventing further UNC issues.

cls
@pushd %~dp0
:::::::::::::::::::
:: your script code here
:::::::::::::::::::
@popd

Notes:

pushd will change your working directory to the scripts location in the new mapped drive.

popd at the end, to clean up the mapped drive.

According to the matplotlib legend documentation:

The location can also be a 2-tuple giving the coordinates of the lower-left corner of the legend in axes coordinates (in which case bbox_to_anchor will be ignored).

Thus, one could use:

plt.legend(loc=(x, y))

to set the legend's lower left corner to the specified (x, y) position.

There are 3 different things we are using here :

1. JPA : Java persistence api which provide specification for persisting, reading, managing data from your java object to relations in database.
2. Hibernate: There are various provider which implement jpa. Hibernate is one of them. So we have other provider as well. But if using jpa with spring it allows you to switch to different providers in future.
3. Spring Data JPA : This is another layer on top of jpa which spring provide to make your life easy.

So lets understand how spring data jpa and spring + hibernate works-

Spring Data JPA:

Let's say you are using spring + hibernate for your application. Now you need to have dao interface and implementation where you will be writing crud operation using SessionFactory of hibernate. Let say you are writing dao class for Employee class, tomorrow in your application you might need to write similiar crud operation for any other entity. So there is lot of boilerplate code we can see here.

Now Spring data jpa allow us to define dao interfaces by extending its repositories(crudrepository, jparepository) so it provide you dao implementation at runtime. You don't need to write dao implementation anymore.Thats how spring data jpa makes your life easy.

The ObjectiveC equivalent is:

    myView.translatesAutoresizingMaskIntoConstraints = NO;

    [[myView.centerXAnchor constraintEqualToAnchor:self.view.centerXAnchor] setActive:YES];

    [[myView.centerYAnchor constraintEqualToAnchor:self.view.centerYAnchor] setActive:YES];

You need to add a width and a height of the background image for it to display properly.

For instance,

.header-shadow{
    background-image: url('../images/header-shade.jpg');
    width: XXpx;
    height: XXpx;
}

As you mentioned that you are using it as a shadow, you can remove the width and add a background-repeat (either vertically or horizontally if required).

For instance,

.header-shadow{
    background-image: url('../images/header-shade.jpg');
    background-repeat: repeat-y; /* for vertical repeat */
    background-repeat: repeat-x; /* for horizontal repeat */
    height: XXpx;
}

PS: XX is a dummy value. You need to replace it with your actual values of your image.

you can use bc as it can also do floats

var=$(echo "1+2"|bc)

The few lines you posted from your script look okay to me. It's probably something a bit deeper.

You need to find which line is giving you this error. Add set -xv to the top of your script. This will print out the line number and the command that's being executed to STDERR. This will help you identify where in your script you're getting this particular error.

BTW, do you have a shebang at the top of your script? When I see something like this, I normally expect its an issue with the Shebang. For example, if you had #! /bin/bash on top, but your bash interpreter is located in /usr/bin/bash, you'll see this error.

EDIT

New question: How can I save the file correctly in the first place, to avoid having to perform this fix every time I resend the file?

Two ways:

1. Select the Edit->EOL Conversion->Unix Format menu item when you edit a file. Once it has the correct line endings, Notepad++ will keep them.
2. To make sure all new files have the correct line endings, go to the Settings->Preferences menu item, and pull up the Preferences dialog box. Select the New Document/Default Directory tab. Under New Document and Format, select the Unix radio button. Click the Close button.

SELECT * FROM SysColumns WHERE Name like 'a%'

Will get you a list of columns, you will want to filter more to restrict it to your target table

From there you can construct some ad-hoc sql

I just found another reason why to get this error. I cleaned my GAC from all versions of a specific library and built my project with reference to specific version deployed together with the executable. When I run the project I got this exception searching for a newer version of the library.

The reason was publisher policy. When I uninstalled library's versions from GAC I forgot to uninstall publisher policy assemblies as well so instead of using my locally deployed assembly the assembly loader found publisher policy in GAC which told it to search for a newer version.

There is an access modifier called "default" in JAVA, which allows direct instance creation of that entity only within that package.

After 2 days looking for answers, the button theming didn't work for me in API < 21.

My only solution is to override AppCompatButton tinting not only with the base app theme "colorButtonNormal" but also the view backgroundTint like this :

public class AppCompatColorButton extends AppCompatButton {

    public AppCompatColorButton(Context context) {
        this(context, null);
    }

    public AppCompatColorButton(Context context, AttributeSet attrs) {
        this(context, attrs, android.support.v7.appcompat.R.attr.buttonStyle);
    }

    public AppCompatColorButton(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);

        if (TintManager.SHOULD_BE_USED) {
            setSupportBackgroundTintList(createButtonColorStateList(getContext(), attrs, defStyleAttr));
        }
    }

    static final int[] DISABLED_STATE_SET = new int[]{-android.R.attr.state_enabled};
    static final int[] FOCUSED_STATE_SET = new int[]{android.R.attr.state_focused};
    static final int[] PRESSED_STATE_SET = new int[]{android.R.attr.state_pressed};
    static final int[] EMPTY_STATE_SET = new int[0];

    private ColorStateList createButtonColorStateList(Context context, AttributeSet attrs, int defStyleAttr) {
        final int[][] states = new int[4][];
        final int[] colors = new int[4];
        int i = 0;

        final int themeColorButtonNormal = ThemeUtils.getThemeAttrColor(context, android.support.v7.appcompat.R.attr.colorButtonNormal);
        /*TypedArray a = context.obtainStyledAttributes(attrs, new int[] { android.R.attr.backgroundTint }, defStyleAttr, 0);
        final int colorButtonNormal = a.getColor(0, themeColorButtonNormal);*/
        TypedArray a = context.obtainStyledAttributes(attrs, android.support.v7.appcompat.R.styleable.View, defStyleAttr, 0);
        final int colorButtonNormal = a.getColor(android.support.v7.appcompat.R.styleable.View_backgroundTint, themeColorButtonNormal);
        a.recycle();
        final int colorControlHighlight = ThemeUtils.getThemeAttrColor(context, android.support.v7.appcompat.R.attr.colorControlHighlight);

        // Disabled state
        states[i] = DISABLED_STATE_SET;
        colors[i] = ThemeUtils.getDisabledThemeAttrColor(context, android.support.v7.appcompat.R.attr.colorButtonNormal);
        i++;

        states[i] = PRESSED_STATE_SET;
        colors[i] = ColorUtils.compositeColors(colorControlHighlight, colorButtonNormal);
        i++;

        states[i] = FOCUSED_STATE_SET;
        colors[i] = ColorUtils.compositeColors(colorControlHighlight, colorButtonNormal);
        i++;

        // Default enabled state
        states[i] = EMPTY_STATE_SET;
        colors[i] = colorButtonNormal;
        i++;

        return new ColorStateList(states, colors);
    }
}

You can then define your Button color like this :

<com.example.views.AppCompatColorButton
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:backgroundTint="#ffff0000"
            app:backgroundTint="#ffff0000"
            android:text="Button"
            android:textColor="@android:color/white" />

Same here. I had this error when running an import command from terminal without activating python3 shell through manage.py in a django project (yes, I am a newbie yet). As one must expect, activating shell allowed the command to be interpreted correctly.

./manage.py shell

and only then

>>> from django.contrib.sites.models import Site

System.arraycopy is probably the most efficient way, but for aesthetics, I'd prefer:

 Arrays.asList(Object_Array).toArray(new String[Object_Array.length]);

Try this:-

printf("Let the Battle Begin!\n");
printf("Press Any Key to Continue\n");
getch();

getch() is used to get a character from console but does not echo to the screen.

Set autoplay=0

As seen here: Autoplay=0 Test

Using sshpass works best. To just include your password in scp use the ' ':

scp user1:'password'@xxx.xxx.x.5:sys_config /var/www/dev/

Note: Git 1.8.2 added the possibility to track branches. See some of the answers below.

It's a little confusing to get used to this, but submodules are not on a branch. They are, like you say, just a pointer to a particular commit of the submodule's repository.

This means, when someone else checks out your repository, or pulls your code, and does git submodule update, the submodule is checked out to that particular commit.

This is great for a submodule that does not change often, because then everyone on the project can have the submodule at the same commit.

If you want to move the submodule to a particular tag:

cd submodule_directory
git checkout v1.0
cd ..
git add submodule_directory
git commit -m "moved submodule to v1.0"
git push

Then, another developer who wants to have submodule_directory changed to that tag, does this

git pull
git submodule update --init

git pull changes which commit their submodule directory points to. git submodule update actually merges in the new code.

Edited: Fixed mistake in code that stopped it working if there were no YourModel entries in the db.

There's a lot of mention of how you should use an AutoField, and of course, where possible you should use that.

However there are legitimate reasons for implementing auto-incrementing fields yourself (such as if you need an id to start from 500 or increment by tens for whatever reason).

In your models.py

from django.db import models

def from_500():
    '''
    Returns the next default value for the `ones` field,
    starts from 500
    '''
    # Retrieve a list of `YourModel` instances, sort them by
    # the `ones` field and get the largest entry
    largest = YourModel.objects.all().order_by('ones').last()
    if not largest:
        # largest is `None` if `YourModel` has no instances
        # in which case we return the start value of 500
        return 500
    # If an instance of `YourModel` is returned, we get it's
    # `ones` attribute and increment it by 1
    return largest.ones + 1

def add_ten():
    ''' Returns the next default value for the `tens` field'''
    # Retrieve a list of `YourModel` instances, sort them by
    # the `tens` field and get the largest entry
    largest = YourModel.objects.all().order_by('tens').last()
    if not largest:
        # largest is `None` if `YourModel` has no instances
        # in which case we return the start value of 10
        return 10
    # If an instance of `YourModel` is returned, we get it's
    # `tens` attribute and increment it by 10
    return largest.tens + 10


class YourModel(model.Model):
    ones = models.IntegerField(primary_key=True,
                               default=from_500)
    tens = models.IntegerField(default=add_ten)

Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

So there is another way you can actually fire it from any language. The best way I think, you can just create a batch file which will call your .dtsx package.

Next you call the batch file from any language. As in windows platform, you can run batch file from anywhere, I think this will be the most generic approach for your purpose. No code dependencies.

Happy coding.. :)

Thanks, Ayan

Another way is :

const result = [] as  any;

SWIFT 3.01

let secondViewController = self.storyboard?.instantiateViewController(withIdentifier: "Conversation_VC") as! Conversation_VC
self.navigationController?.pushViewController(secondViewController, animated: true)

Alternative (Insert tooltip to user):

<style>
    a.tooltips {
        position: relative;
        display: inline;
    }
    a.tooltips span {
        position: absolute;
        width: 240px;
        color: #FFFFFF;
        background: #000000;
        height: 30px;
        line-height: 30px;
        text-align: center;
        visibility: hidden;
        border-radius: 6px;
    }
    a.tooltips span:after {
        content: '';
        position: absolute;
        top: 100%;
        left: 50%;
        margin-left: -8px;
        width: 0;
        height: 0;
        border-top: 8px solid #000000;
        border-right: 8px solid transparent;
        border-left: 8px solid transparent;
    }
    a:hover.tooltips span {
        visibility: visible;
        opacity: 0.8;
        bottom: 30px;
        left: 50%;
        margin-left: -76px;
        z-index: 999;
    }
</style>
<a class="tooltips" href="#">\\server\share\docs<span>Copy link and open in Explorer</span></a>

$string="1,2,3,4,5";
$array=array_map('intval', explode(',', $string));
$array = implode("','",$array);
$query=mysqli_query($conn, "SELECT name FROM users WHERE id IN ('".$array."')");

NB: the syntax is:

SELECT * FROM table WHERE column IN('value1','value2','value3')

I think the problem is given in the error message, although it is not very easy to spot:

IndexError: too many indices for array
xs  = data[:, col["l1"     ]]

'Too many indices' means you've given too many index values. You've given 2 values as you're expecting data to be a 2D array. Numpy is complaining because data is not 2D (it's either 1D or None).

This is a bit of a guess - I wonder if one of the filenames you pass to loadfile() points to an empty file, or a badly formatted one? If so, you might get an array returned that is either 1D, or even empty (np.array(None) does not throw an Error, so you would never know...). If you want to guard against this failure, you can insert some error checking into your loadfile function.

I highly recommend in your for loop inserting:

print(data)

This will work in Python 2.x or 3.x and might reveal the source of the issue. You might well find it is only one value of your outputs_l1 list (i.e. one file) that is giving the issue.

You can handle this question with just two line coding:

_(flatArray).forEach(f=>
           {f.nodes=_(flatArray).filter(g=>g.parentId==f.id).value();});

var resultArray=_(flatArray).filter(f=>f.parentId==null).value();

Test Online (see the browser console for created tree)

Requirements:

1- Install lodash 4 (a Javascript library for manipulating objects and collections with performant methods => like the Linq in c#) Lodash

2- A flatArray like below:

    var flatArray=
    [{
      id:1,parentId:null,text:"parent1",nodes:[]
    }
   ,{
      id:2,parentId:null,text:"parent2",nodes:[]
    }
    ,
    {
      id:3,parentId:1,text:"childId3Parent1",nodes:[]
    }
    ,
    {
      id:4,parentId:1,text:"childId4Parent1",nodes:[]
    }
    ,
    {
      id:5,parentId:2,text:"childId5Parent2",nodes:[]
    }
    ,
    {
      id:6,parentId:2,text:"childId6Parent2",nodes:[]
    }
    ,
    {
      id:7,parentId:3,text:"childId7Parent3",nodes:[]
    }
    ,
    {
      id:8,parentId:5,text:"childId8Parent5",nodes:[]
    }];

Thank Mr. Bakhshabadi

Good luck

If you want to create a "desired" Guid you can do

var tempGuid = Guid.Parse("<guidValue>");

where <guidValue> would be something like 1A3B944E-3632-467B-A53A-206305310BAE.

Or you can do it like this!

    def skip_elements(elements):
        # Initialize variables
        new_list = []
        i = 0

        # Iterate through the list
        for words in elements:

            # Does this element belong in the resulting list?
            if i <= len(elements):
                # Add this element to the resulting list
                new_list.append(elements[i])
            # Increment i
                i += 2

        return new_list

    print(skip_elements(["a", "b", "c", "d", "e", "f", "g"])) # Should be ['a', 'c', 'e', 'g']
    print(skip_elements(['Orange', 'Pineapple', 'Strawberry', 'Kiwi', 'Peach'])) # Should be ['Orange', 'Strawberry', 'Peach']
    print(skip_elements([])) # Should be []

If you know the sessionID then you can use the following:

SELECT * FROM sys.dm_exec_requests WHERE session_id = 62

Or if you want to narrow it down:

SELECT command, percent_complete, start_time FROM sys.dm_exec_requests WHERE session_id = 62

      var data = [];

      data  = {{ jdata|safe }}; //parse through js
      var i = 0 ;
      for (i=0;i<data.length;i++){
         data[i] = data[i].value;
      }

How about something like

import numpy as np
import matplotlib.pyplot as plt

V = np.array([[1,1], [-2,2], [4,-7]])
origin = np.array([[0, 0, 0],[0, 0, 0]]) # origin point

plt.quiver(*origin, V[:,0], V[:,1], color=['r','b','g'], scale=21)
plt.show()

Then to add up any two vectors and plot them to the same figure, do so before you call plt.show(). Something like:

plt.quiver(*origin, V[:,0], V[:,1], color=['r','b','g'], scale=21)
v12 = V[0] + V[1] # adding up the 1st (red) and 2nd (blue) vectors
plt.quiver(*origin, v12[0], v12[1])
plt.show()

NOTE: in Python2 use origin[0], origin[1] instead of *origin

Using the wildcard * selector in CSS to override inheritance for all attributes of an element (by setting these back to their initial state).

An example of its use:

li * {
   display: initial;
}

Alternatively, can use for particular table

 <table style="width:1000px; height:100px;">
    <tr>
        <td align="center" valign="top">Text</td> //Remove it
        <td class="tableFormatter">Text></td>
    </tr>
</table>

Add this css in external file

.tableFormatter
{
width:100%;
vertical-align:top;
text-align:center;
}

If you can't use the TextDecoder API because it is not supported on IE:

1. You can use the FastestSmallestTextEncoderDecoder polyfill recommended by the Mozilla Developer Network website;
2. You can use this function also provided at the MDN website:

function utf8ArrayToString(aBytes) {_x000D_
    var sView = "";_x000D_
    _x000D_
    for (var nPart, nLen = aBytes.length, nIdx = 0; nIdx < nLen; nIdx++) {_x000D_
        nPart = aBytes[nIdx];_x000D_
        _x000D_
        sView += String.fromCharCode(_x000D_
            nPart > 251 && nPart < 254 && nIdx + 5 < nLen ? /* six bytes */_x000D_

                (nPart - 252) * 1073741824 + (aBytes[++nIdx] - 128 << 24) + (aBytes[++nIdx] - 128 << 18) + (aBytes[++nIdx] - 128 << 12) + (aBytes[++nIdx] - 128 << 6) + aBytes[++nIdx] - 128_x000D_
            : nPart > 247 && nPart < 252 && nIdx + 4 < nLen ? /* five bytes */_x000D_
                (nPart - 248 << 24) + (aBytes[++nIdx] - 128 << 18) + (aBytes[++nIdx] - 128 << 12) + (aBytes[++nIdx] - 128 << 6) + aBytes[++nIdx] - 128_x000D_

Since you already had a running version of WAMP and it stopped working, you probably had VCRUNTIME140.dll already installed. In that case:

1. Open Programs and Features
2. Right-click on the respective Microsoft Visual C++ 20xx Redistributable installers and choose "Change"
3. Choose "Repair". Do this for both x86 and x64

This did the trick for me.

PyCharm Version 3.4.1(For all files in the project):

File -> Preferences -> Editor (IDE Settings) -> Appearance -> mark 'Show line numbers'

PyCharm Version 3.4.1(only for existing file in the project):

View -> Active Editor -> Show Line Numbers

i think this can be as simple let as assume that you are going to pass multiple parameters to you action as you read up there actions accept only two parameters context and payload which is your data you want to pass in action so let take an example

Setting up Action

instead of

actions: {
        authenticate: ({ commit }, token, expiration) => commit('authenticate', token, expiration)
    }

do

actions: {
        authenticate: ({ commit }, {token, expiration}) => commit('authenticate', token, expiration)
    }

Calling (dispatching) Action

instead of

this.$store.dispatch({
                  type: 'authenticate',
                  token: response.body.access_token,
                  expiration: response.body.expires_in + Date.now()
              })

do

this.$store.dispatch('authenticate',{
                  token: response.body.access_token,
                  expiration: response.body.expires_in + Date.now()
              })

hope this gonna help

One line is Chris's answer is wrong.

newFrame.size.height = maximumLabelSize.height;

should be

newFrame.size.height = expectedLabelSize.height;

Other than that, it's the correct solution.

The only difference is that you're creating an unnecessary promise when you do return Promise.resolve("bbb"). Returning a promise from an onFulfilled() handler kicks off promise resolution. That's how promise chaining works.

As to "how do you calculate" Big O, this is part of Computational complexity theory. For some (many) special cases you may be able to come with some simple heuristics (like multiplying loop counts for nested loops), esp. when all you want is any upper bound estimation, and you do not mind if it is too pessimistic - which I guess is probably what your question is about.

If you really want to answer your question for any algorithm the best you can do is to apply the theory. Besides of simplistic "worst case" analysis I have found Amortized analysis very useful in practice.

In addition to solutions proposed, and in case you have a 1D range to 1D array, i prefer to process it through a function like below. The reason is simple: If for any reason your range is reduced to 1 element range, as far as i know the command Range().Value will not return a variant array but just a variant and you will not be able to assign a variant variable to a variant array (previously declared).

I had to convert a variable size range to a double array, and when the range was of 1 cell size, i was not able to use a construct like range().value so i proceed with a function like below.

Public Function Rng2Array(inputRange As Range) As Double()

    Dim out() As Double    
    ReDim out(inputRange.Columns.Count - 1)

    Dim cell As Range
    Dim i As Long
    For i = 0 To inputRange.Columns.Count - 1
        out(i) = inputRange(1, i + 1) 'loop over a range "row"
    Next

    Rng2Array = out  
End Function

I use both hidden and checkbox type input to ensure either 0 or 1 submitted to the form. Make sure the field name are the same so only one input will be sent to the server.

<input type="hidden" :name="fieldName" value="0">
<input type="checkbox" :name="fieldName" value="1" :checked="checked">

You can only access cookies for a specific site. Using document.cookie you will get a list of escaped key=value pairs seperated by a semicolon.

secret=do%20not%20tell%you;last_visit=1225445171794

To simplify the access, you have to parse the string and unescape all entries:

var getCookies = function(){
  var pairs = document.cookie.split(";");
  var cookies = {};
  for (var i=0; i<pairs.length; i++){
    var pair = pairs[i].split("=");
    cookies[(pair[0]+'').trim()] = unescape(pair.slice(1).join('='));
  }
  return cookies;
}

So you might later write:

var myCookies = getCookies();
alert(myCookies.secret); // "do not tell you"

Or for what seems like rampant overkill, but is actually simplistic ... Pretty much covers all of your cases, and no empty string or unary concerns.

In the case the first arg is '-v', then do your conditional ps -ef, else in all other cases throw the usage.

#!/bin/sh
case $1 in
  '-v') if [ "$1" = -v ]; then
         echo "`ps -ef | grep -v '\['`"
        else
         echo "`ps -ef | grep '\[' | grep root`"
        fi;;
     *) echo "usage: $0 [-v]"
        exit 1;; #It is good practice to throw a code, hence allowing $? check
esac

If one cares not where the '-v' arg is, then simply drop the case inside a loop. The would allow walking all the args and finding '-v' anywhere (provided it exists). This means command line argument order is not important. Be forewarned, as presented, the variable arg_match is set, thus it is merely a flag. It allows for multiple occurrences of the '-v' arg. One could ignore all other occurrences of '-v' easy enough.

#!/bin/sh

usage ()
 {
  echo "usage: $0 [-v]"
  exit 1
 }

unset arg_match

for arg in $*
 do
  case $arg in
    '-v') if [ "$arg" = -v ]; then
           echo "`ps -ef | grep -v '\['`"
          else
           echo "`ps -ef | grep '\[' | grep root`"
          fi
          arg_match=1;; # this is set, but could increment.
       *) ;;
  esac
done

if [ ! $arg_match ]
 then
  usage
fi

But, allow multiple occurrences of an argument is convenient to use in situations such as:

$ adduser -u:sam -s -f -u:bob -trace -verbose

We care not about the order of the arguments, and even allow multiple -u arguments. Yes, it is a simple matter to also allow:

$ adduser -u sam -s -f -u bob -trace -verbose

You may use the == operator to compare unicode objects for equality.

>>> s1 = u'Hello'
>>> s2 = unicode("Hello")
>>> type(s1), type(s2)
(<type 'unicode'>, <type 'unicode'>)
>>> s1==s2
True
>>> 
>>> s3='Hello'.decode('utf-8')
>>> type(s3)
<type 'unicode'>
>>> s1==s3
True
>>> 

But, your error message indicates that you aren't comparing unicode objects. You are probably comparing a unicode object to a str object, like so:

>>> u'Hello' == 'Hello'
True
>>> u'Hello' == '\x81\x01'
__main__:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False

See how I have attempted to compare a unicode object against a string which does not represent a valid UTF8 encoding.

Your program, I suppose, is comparing unicode objects with str objects, and the contents of a str object is not a valid UTF8 encoding. This seems likely the result of you (the programmer) not knowing which variable holds unicide, which variable holds UTF8 and which variable holds the bytes read in from a file.

I recommend http://nedbatchelder.com/text/unipain.html, especially the advice to create a "Unicode Sandwich."

i use firebase-database in html signup but last error i cannot understand if anybody know tell me . error is "Failed to load resource: the server responded with a status of 404 ()"

org.springframework.core.io.Resource is part of spring-core-<version>.jar

But this lib is already in your lib folder. So I guess it is just a Deployment Problem. -- Try to clean your server and redeploy your application.

PHP Error - Better error reporting for PHP

This is very easy to use library (actually a file) to debug your PHP scripts.

The only thing that you need to do is to include one file as below (at the beginning on your code):

require('php_error.php');
\php_error\reportErrors();

Then all errors will give you info such as backtrace, code context, function arguments, server variables, etc. For example:

Features include:

• trivial to use, it's just one file
• errors displayed in the browser for normal and ajaxy requests
• AJAX requests are paused, allowing you to automatically re-run them
• makes errors as strict as possible (encourages code quality, and tends to improve performance)
• code snippets across the whole stack trace
• provides more information (such as full function signatures)
• fixes some error messages which are just plain wrong
• syntax highlighting
• looks pretty!
• customization
• manually turn it on and off
• run specific sections without error reporting
• ignore files allowing you to avoid highlighting code in your stack trace
• application files; these are prioritized when an error strikes!

DTrace

If your system supports DTrace dynamic tracing (installed by default on OS X) and your PHP is compiled with the DTrace probes enabled (--enable-dtrace) which should be by default, this command can help you to debug PHP script with no time:

sudo dtrace -qn 'php*:::function-entry { printf("%Y: PHP function-entry:\t%s%s%s() in %s:%d\n", walltimestamp, copyinstr(arg3), copyinstr(arg4), copyinstr(arg0), basename(copyinstr(arg1)), (int)arg2); }'

So given the following alias has been added into your rc files (e.g. ~/.bashrc, ~/.bash_aliases):

alias trace-php='sudo dtrace -qn "php*:::function-entry { printf(\"%Y: PHP function-entry:\t%s%s%s() in %s:%d\n\", walltimestamp, copyinstr(arg3), copyinstr(arg4), copyinstr(arg0), basename(copyinstr(arg1)), (int)arg2); }"'

you may trace your script with easy to remember alias: trace-php.

Here is more advanced dtrace script, just save it into dtruss-php.d, make it executable (chmod +x dtruss-php.d) and run:

#!/usr/sbin/dtrace -Zs
# See: https://github.com/kenorb/dtruss-lamp/blob/master/dtruss-php.d

#pragma D option quiet

php*:::compile-file-entry
{
    printf("%Y: PHP compile-file-entry:\t%s (%s)\n", walltimestamp, basename(copyinstr(arg0)), copyinstr(arg1));
}

php*:::compile-file-return
{
    printf("%Y: PHP compile-file-return:\t%s (%s)\n", walltimestamp, basename(copyinstr(arg0)), basename(copyinstr(arg1)));
}

php*:::error
{
    printf("%Y: PHP error message:\t%s in %s:%d\n", walltimestamp, copyinstr(arg0), basename(copyinstr(arg1)), (int)arg2);
}

php*:::exception-caught
{
    printf("%Y: PHP exception-caught:\t%s\n", walltimestamp, copyinstr(arg0));
}

php*:::exception-thrown
{
    printf("%Y: PHP exception-thrown:\t%s\n", walltimestamp, copyinstr(arg0));
}

    printf("%Y: PHP execute-entry:\t%s:%d\n", walltimestamp, basename(copyinstr(arg0)), (int)arg1);
}

php*:::execute-return
{
    printf("%Y: PHP execute-return:\t%s:%d\n", walltimestamp, basename(copyinstr(arg0)), (int)arg1);
}

php*:::function-entry
{
    printf("%Y: PHP function-entry:\t%s%s%s() in %s:%d\n", walltimestamp, copyinstr(arg3), copyinstr(arg4), copyinstr(arg0), basename(copyinstr(arg1)), (int)arg2);
}

php*:::function-return
{
    printf("%Y: PHP function-return:\t%s%s%s() in %s:%d\n", walltimestamp, copyinstr(arg3), copyinstr(arg4), copyinstr(arg0), basename(copyinstr(arg1)), (int)arg2);
}

php*:::request-shutdown
{
    printf("%Y: PHP request-shutdown:\t%s at %s via %s\n", walltimestamp, basename(copyinstr(arg0)), copyinstr(arg1), copyinstr(arg2));
}

php*:::request-startup
{
    printf("%Y, PHP request-startup:\t%s at %s via %s\n", walltimestamp, basename(copyinstr(arg0)), copyinstr(arg1), copyinstr(arg2));
}

Here is simple usage:

1. Run: sudo dtruss-php.d.
2. On another terminal run: php -r "phpinfo();".

To test that, you can go to any docroot with index.php and run PHP builtin server by:

php -S localhost:8080

After that you can access the site at http://localhost:8080/ (or choose whatever port is convenient for you). From there access some pages to see the trace output.

Note: Dtrace is available on OS X by default, on Linux you probably need dtrace4linux or check for some other alternatives.

See: Using PHP and DTrace at php.net

SystemTap

Alternatively check for SystemTap tracing by installing SystemTap SDT development package (e.g. yum install systemtap-sdt-devel).

Here is example script (all_probes.stp) for tracing all core PHP static probe points throughout the duration of a running PHP script with SystemTap:

probe process("sapi/cli/php").provider("php").mark("compile__file__entry") {
    printf("Probe compile__file__entry\n");
    printf("  compile_file %s\n", user_string($arg1));
    printf("  compile_file_translated %s\n", user_string($arg2));
}
probe process("sapi/cli/php").provider("php").mark("compile__file__return") {
    printf("Probe compile__file__return\n");
    printf("  compile_file %s\n", user_string($arg1));
    printf("  compile_file_translated %s\n", user_string($arg2));
}
probe process("sapi/cli/php").provider("php").mark("error") {
    printf("Probe error\n");
    printf("  errormsg %s\n", user_string($arg1));
    printf("  request_file %s\n", user_string($arg2));
    printf("  lineno %d\n", $arg3);
}

Here is a non-regex heap allocation friendly fast solution which was what I was looking for.

Unsafe edition.

public static unsafe void ToAlphaNumeric(ref string input)
{
    fixed (char* p = input)
    {
        int offset = 0;
        for (int i = 0; i < input.Length; i++)
        {
            if (char.IsLetterOrDigit(p[i]))
            {
                p[offset] = input[i];
                offset++;
            }
        }
        ((int*)p)[-1] = offset; // Changes the length of the string
        p[offset] = '\0';
    }
}

And for those who don't want to use unsafe or don't trust the string length hack.

public static string ToAlphaNumeric(string input)
{
    int j = 0;
    char[] newCharArr = new char[input.Length];

    for (int i = 0; i < input.Length; i++)
    {
        if (char.IsLetterOrDigit(input[i]))
        {
            newCharArr[j] = input[i];
            j++;
        }
    }

    Array.Resize(ref newCharArr, j);

    return new string(newCharArr);
}

$date_to_be-added="2018-04-11 10:04:46";
$added_date=date("Y-m-d H:i:s",strtotime('+24 hours', strtotime($date_to_be)));

A combination of date() and strtotime() functions will do the trick.

Just give full path to exclusion file: eg..

-- no - - - - -xcopy c:\t1 c:\t2 /EXCLUDE:list-of-excluded-files.txt

correct - - - xcopy c:\t1 c:\t2 /EXCLUDE:C:\list-of-excluded-files.txt

In this example the file would be located " C:\list-of-excluded-files.txt "

or...

correct - - - xcopy c:\t1 c:\t2 /EXCLUDE:C:\mybatch\list-of-excluded-files.txt

In this example the file would be located " C:\mybatch\list-of-excluded-files.txt "

Full path fixes syntax error.

Two possible options (there might be more of course):

1. You can use the crypto/rand package that supports reading random byte arrays (from /dev/urandom) and is geared towards cryptographic random generation. see http://golang.org/pkg/crypto/rand/#example_Read . It might be slower than normal pseudo-random number generation though.

2. Take a random number and hash it using md5 or something like this.

I found the solution, it is a good library.

Cross platform 256bit AES encryption / decryption.

This project contains the implementation of 256 bit AES encryption which works on all the platforms (C#, iOS, Android). One of the key objective is to make AES work on all the platforms with simple implementation.

Platforms Supported: iOS , Android , Windows (C#).

Or

You can use reduce method as bellow; If you change the 0(zero) to 1 or other numbers, it will add it to total number. For example, this example gives the total number as 31 however if we change 0 to 1, total number will be 32.

const batteryBatches = [4, 5, 3, 4, 4, 6, 5];

let totalBatteries= batteryBatches.reduce((acc,val) => acc + val ,0)

Any problems with the following way of doing it?

int CharToInt(const char c)
{
    switch (c)
    {
    case '0':
        return 0;
    case '1':
        return 1;
    case '2':
        return 2;
    case '3':
        return 3;
    case '4':
        return 4;
    case '5':
        return 5;
    case '6':
        return 6;
    case '7':
        return 7;
    case '8':
        return 8;
    case '9':
        return 9;
    default:
        return 0;
    }
}

Try this :

<style type="text/css">
        .myTableStyle
        {
           position:absolute;
           top:50%;
           left:50%; 

            /*Alternatively you could use: */
           /*
              position: fixed;
               bottom: 50%;
               right: 50%;
           */

Don't know why anyone else hasn't said this yet;

NORMALISE.

You've got a table that models competitions? Competitions are made up of Competitors? You need a distinct list of Competitors in one or more Competitions......

You should have the following tables.....

CREATE TABLE Competitor (
    [CompetitorID] INT IDENTITY(1,1) PRIMARY KEY
    , [CompetitorName] NVARCHAR(255)
    )

CREATE TABLE Competition (
    [CompetitionID] INT IDENTITY(1,1) PRIMARY KEY
    , [CompetitionName] NVARCHAR(255)
    )

CREATE TABLE CompetitionCompetitors (
    [CompetitionID] INT
    , [CompetitorID] INT
    , [Score] INT

    , PRIMARY KEY (
        [CompetitionID]
        , [CompetitorID]
        )
    )

With Constraints on CompetitionCompetitors.CompetitionID and CompetitorID pointing at the other tables.

With this kind of table structure -- your keys are all simple INTS -- there doesn't seem to be a good NATURAL KEY that would fit the model so I think a SURROGATE KEY is a good fit here.

So if you had this then to get the the distinct list of competitors in a particular competition you can issue a query like this:

DECLARE @CompetitionName VARCHAR(50) SET @CompetitionName = 'London Marathon'

    SELECT
        p.[CompetitorName] AS [CompetitorName]
    FROM
        Competitor AS p
    WHERE
        EXISTS (
            SELECT 1
            FROM
                CompetitionCompetitor AS cc
                JOIN Competition AS c ON c.[ID] = cc.[CompetitionID]
            WHERE
                cc.[CompetitorID] = p.[CompetitorID]
                AND cc.[CompetitionName] = @CompetitionNAme
        )

And if you wanted the score for each competition a competitor is in:

SELECT
    p.[CompetitorName]
    , c.[CompetitionName]
    , cc.[Score]
FROM
    Competitor AS p
    JOIN CompetitionCompetitor AS cc ON cc.[CompetitorID] = p.[CompetitorID]
    JOIN Competition AS c ON c.[ID] = cc.[CompetitionID]

And when you have a new competition with new competitors then you simply check which ones already exist in the Competitors table. If they already exist then you don't insert into Competitor for those Competitors and do insert for the new ones.

Then you insert the new Competition in Competition and finally you just make all the links in CompetitionCompetitors.

The .htaccess is either in the root-directory of your webpage or in the directory you want to protect.

Make sure to make them visible in your filesystem, because AFAIK (I'm no unix expert either) files starting with a period are invisible by default on unix-systems.

I recommend reading this post.

When using AnyCPU, the semantics are the following:

• If the process runs on a 32-bit Windows system, it runs as a 32-bit process. CIL is compiled to x86 machine code.
• If the process runs on a 64-bit Windows system, it runs as a 32-bit process. CIL is compiled to x86 machine code.
• If the process runs on an ARM Windows system, it runs as a 32-bit process. CIL is compiled to ARM machine code.

On Windows they get installed to separate folders, "C:\python26" and "C:\python31", but the executables have the same "python.exe" name.

I created another "C:\python" folder that contains "python.bat" and "python3.bat" that serve as wrappers to "python26" and "python31" respectively, and added "C:\python" to the PATH environment variable.

This allows me to type python or python3 in my .bat Python wrappers to start the one I desire.

On Linux, you can use the #! trick to specify which version you want a script to use.

If you are dealing with a lower level time object (I often just use integers), and don't want to write a custom filter for whatever reason, an approach I use is to pass the strftime function into the template as a variable, where it can be called where you need it.

For example:

import time
context={
    'now':int(time.time()),
    'strftime':time.strftime }  # Note there are no brackets () after strftime
                                # This means we are passing in a function, 
                                # not the result of a function.

self.response.write(jinja2.render_template('sometemplate.html', **context))

Which can then be used within sometemplate.html:

<html>
    <body>
        <p>The time is {{ strftime('%H:%M%:%S',now) }}, and 5 seconds ago it was {{ strftime('%H:%M%:%S',now-5) }}.
    </body>
</html>

var uniq = allvalues.GroupBy(x => x.Id).Select(y=>y.First()).Distinct();

Easy and simple

You can use JavaScript functions like replace, and you can wrap the jQuery code in brackets:

var value = ($("#text").val()).replace(".", ":");

This can also happen if you've been working on your scripts and functions and have been moving them around (i.e. changed the location of the definition) which could have accidentally created a looping reference.

You may find that the situation is solved if you just reset the iPython kernal to clear any old assignments:

%reset

or menu->restart terminal

use some thing like

import java.io.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;

//method to convert Document to String
public String getStringFromDocument(Document doc)
{
    try
    {
       DOMSource domSource = new DOMSource(doc);
       StringWriter writer = new StringWriter();
       StreamResult result = new StreamResult(writer);
       TransformerFactory tf = TransformerFactory.newInstance();
       Transformer transformer = tf.newTransformer();
       transformer.transform(domSource, result);
       return writer.toString();
    }
    catch(TransformerException ex)
    {
       ex.printStackTrace();
       return null;
    }
} 

In my case, I was inflating a PopupMenu at the very beginning of the activity i.e on onCreate()... I fixed it by putting it in a Handler

  new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                PopupMenu popuMenu=new PopupMenu(SplashScreen.this,binding.progressBar);
                popuMenu.inflate(R.menu.bottom_nav_menu);
                popuMenu.show();
            }
        },100);

Update for 2020: Sticking to the original question of 16x16 versus 32x32 icons: the current recommendation should be to provide a 32x32 icon, skipping 16x16 entirely. All current browsers and devices support 32x32 icons. The icon will routinely be upscaled to as much as 192x192 depending on the environment (assuming there are no larger sizes available or the system didn't recognize them). Upscaling from ultra low resolution has a noticeable effect so better stick to 32x32 as the smallest baseline.

For IE, Microsoft recommends 16x16, 32x32 and 48x48 packed in the favicon.ico file.

For iOS, Apple recommends specific file names and resolutions, at most 180x180 for latest devices running iOS 8.

Android Chrome primarily uses a manifest and also relies on the Apple touch icon.

IE 10 on Windows 8.0 requires PNG pictures and a background color and IE 11 on Windows 8.1 and 10 accepts several PNG pictures declared in a dedicated XML file called browserconfig.xml.

Safari for Mac OS X El Capitan introduces an SVG icon for pinned tabs.

Some other platforms look for PNG files with various resolutions, like the 96x96 picture for Google TV or the 228x228 picture for Opera Coast.

Look at this favicon pictures list for a complete reference.

TLDR: This favicon generator can generate all these files at once. The generator can also be implemented as a WordPress plugin. Full disclosure: I am the author of this site.

You could use   in R markdown to create a new blank line.

For example, in your .Rmd file:

I want 3 new lines: 

 
 
 

End of file. 

You can make you request headers by yourself using:

// open a socket connection on port 80
$fp = fsockopen($host, 80);

// send the request headers:
fputs($fp, "POST $path HTTP/1.1\r\n");
fputs($fp, "Host: $host\r\n");
fputs($fp, "Referer: $referer\r\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
fputs($fp, "Content-length: ". strlen($data) ."\r\n");
fputs($fp, "Connection: close\r\n\r\n");
fputs($fp, $data);

$result = ''; 
while(!feof($fp)) {
    // receive the results of the request
    $result .= fgets($fp, 128);
}

// close the socket connection:
fclose($fp);

Like writen on how make request

Smallest solution:

var regExp=/\s+/g, newString=oldString.replace(regExp,' ');

Had it been on Linux the problem would be that localhost is the loopback interface, you need to application to bind to your network interface.

You can use the netstat to confirm that it is not bound to the expected network interface.

You can make this work by invoking the program with the system parameter java.rmi.server.hostname="YOUR_IP", either as an environment variable or using

java -Djava.rmi.server.hostname=YOUR_IP YOUR_APP

When you say

foo = 'bar'
baz(foo)

you are not passing foo to the baz function. foo is just a name used to represent a value, in this case 'bar', and that value is passed to the baz function.

Alternatively you could use minio-js client library get-object.js

var Minio = require('minio')

var s3Client = new Minio({
  endPoint: 's3.amazonaws.com',
  accessKey: 'YOUR-ACCESSKEYID',
  secretKey: 'YOUR-SECRETACCESSKEY'
})

var size = 0
// Get a full object.
s3Client.getObject('my-bucketname', 'my-objectname', function(e, dataStream) {
  if (e) {
    return console.log(e)
  }
  dataStream.on('data', function(chunk) {
    size += chunk.length
  })
  dataStream.on('end', function() {
    console.log("End. Total size = " + size)
  })
  dataStream.on('error', function(e) {
    console.log(e)
  })
})

Disclaimer: I work for Minio Its open source, S3 compatible object storage written in golang with client libraries available in Java, Python, Js, golang.

This works for me:

# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = False

ALLOWED_HOSTS = ['localhost', '127.0.0.1']

The -i flag specifies the private key (.pem file) to use. If you don't specify that flag (as in your first command) it will use your default ssh key (usually under ~/.ssh/).

So in your first command, you are actually asking scp to upload the .pem file itself using your default ssh key. I don't think that is what you want.

Try instead with:

scp -r -i /Applications/XAMPP/htdocs/keypairfile.pem uploads/* ec2-user@publicdns:/var/www/html/uploads

The quickest and the most intuitive method of them all is to remap ) for walk-down-commenting of lines, and then ( for walk-up-uncommenting. Try it and you won't go back.

In Ruby or Bash, with 2-space indents:

map ) I# <Esc>j
map ( k^2x

In C/C++ or PHP, with 4-space indents:

map ) I//  <Esc>j
map ( k^4x

Downsides are that you lose ( and ) for sentence-movement (but das can fill in there), and you'll occasionally fall back on select-and-replace or CtrlV for handling long sections. But that's pretty rare.

And for C-style, the long comments are best handled with:

set cindent
set formatoptions=tcqr

... Which combines well with using V[move]gq to redo the word-wrapping.

You can write the below code:-

create procedure spCreateTable
   as
    begin
       create table testtb(Name varchar(20))
    end

execute it as:-

exec spCreateTable

I'd say return null instead of an empty object.

But the specific instance that you have mentioned here, you are searching for an user by user id, which is sort of the key to that user, in that case I'd probably want to to throw an exception if no user instance instance is found.

This is the rule I generally follow:

• If no result found on a find by primary key operation, throw ObjectNotFoundException.
• If no result found on a find by any other criteria, return null.
• If no result found on a find by a non-key criteria that may return a multiple objects return an empty collection.

I figured out why the portrait view wasn't totally filling the viewport. At least in my case, it was because the scrollbar was always showing. In addition to the viewport code above, try adding this:

    browser.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
    browser.setScrollbarFadingEnabled(false);

This causes the scrollbar to not take up layout space, and allows the webpage to fill the viewport.

Hope this helps

(The typical method would be to use plot just once to set up the limits, possibly to include the range of all series combined, and then to use points and lines to add the separate series.) To use plot multiple times with par(new=TRUE) you need to make sure that your first plot has a proper ylim to accept the all series (and in another situation, you may need to also use the same strategy for xlim):

# first plot
plot(x, y1, ylim=range(c(y1,y2)))

# second plot  EDIT: needs to have same ylim
par(new = TRUE)
plot(x, y2, ylim=range(c(y1,y2)), axes = FALSE, xlab = "", ylab = "")

This next code will do the task more compactly, by default you get numbers as points but the second one gives you typical R-type-"points":

  matplot(x, cbind(y1,y2))
  matplot(x, cbind(y1,y2), pch=1)

It is also possible to split the string into a character array using fold and then iterate over this array:

for char in `echo "??????" | fold -w1`; do
    echo $char
done

Wherever possible when adding Modernizr tests you should add a test for a feature, rather than a device or operating system. There's nothing wrong with adding ten tests all testing for iPhone if that's what it takes. Some things just can't be feature detected.

    Modernizr.addTest('inpagevideo', function ()
    {
        return navigator.userAgent.match(/(iPhone|iPod)/g) ? false : true;
    });

For instance on the iPhone (not the iPad) video cannot be played inline on a webpage, it opens up full screen. So I created a test 'no-inpage-video'

You can then use this in css (Modernizr adds a class .no-inpagevideo to the <html> tag if the test fails)

.no-inpagevideo video.product-video 
{
     display: none;
}

This will hide the video on iPhone (what I'm actually doing in this case is showing an alternative image with an onclick to play the video - I just don't want the default video player and play button to show).

I wanted a simple example of the use of case that I could play with, this doesn't even need a table. This returns odd or even depending whether seconds is odd or even

SELECT CASE MOD(SECOND(NOW()),2) WHEN 0 THEN 'odd' WHEN 1 THEN 'even' END;

The solution is uninstall the xampp and reinstall it. it will be work

For what it's worth, when I did this I found that no folder should be include in the path in the css file. For instance if I have app/assets/images/example.png, and I put this in my css file...

div.example { background: url('example.png'); }

... then somehow it magically works. I figured this out by running the rake assets:precompile task, which just sucks everything out of all your load paths and dumps it in a junk drawer folder: public/assets. That's ironic, IMO...

In any case this means you don't need to put any folder paths, everything in your assets folders will all end up living in one huge directory. How this system resolves file name conflicts is unclear, you may need to be careful about that.

Kind of frustrating there aren't better docs out there for this big of a change.

I found that using EXISTS keyword is often really slow (that is very true in Microsoft Access). I instead use the join operator in this manner : should-i-use-the-keyword-exists-in-sql

Basically, in regular expression form: [a-zA-Z_$][0-9a-zA-Z_$]*. In other words, the first character can be a letter or _ or $, and the other characters can be letters or _ or $ or numbers.

Note: While other answers have pointed out that you can use Unicode characters in JavaScript identifiers, the actual question was "What characters should I use for the name of an extension library like jQuery?" This is an answer to that question. You can use Unicode characters in identifiers, but don't do it. Encodings get screwed up all the time. Keep your public identifiers in the 32-126 ASCII range where it's safe.

Same error in slightly different circumstances, on MacOs. Apparently setuptools versions past 45 can expose some issues and this command got me past it: pip3 install setuptools==45

ActivityLifecycleCallbacks might be of interest, but it isn't well documented.

Though, if you call registerActivityLifecycleCallbacks() you should be able to get callbacks for when Activities are created, destroyed, etc. You can call getComponentName() for the Activity.

You need module.exports:

Exports

An object which is shared between all instances of the current module and made accessible through require(). exports is the same as the module.exports object. See src/node.js for more information. exports isn't actually a global but rather local to each module.

For example, if you would like to expose variableName with value "variableValue" on sourceFile.js then you can either set the entire exports as such:

module.exports = { variableName: "variableValue" };

Or you can set the individual value with:

module.exports.variableName = "variableValue";

To consume that value in another file, you need to require(...) it first (with relative pathing):

const sourceFile = require('./sourceFile');
console.log(sourceFile.variableName);

Alternatively, you can deconstruct it.

const { variableName } = require('./sourceFile');
//            current directory --^
// ../     would be one directory down
// ../../  is two directories down

If all you want out of the file is variableName then

./sourceFile.js:

const variableName = 'variableValue'
module.exports = variableName

./consumer.js:

const variableName = require('./sourceFile')

Edit (2020):

Since Node.js version 8.9.0, you can also use ECMAScript Modules with varying levels of support. The documentation.

• For Node v13.9.0 and beyond, experimental modules are enabled by default
• For versions of Node less than version 13.9.0, use --experimental-modules

Node.js will treat the following as ES modules when passed to node as the initial input, or when referenced by import statements within ES module code:

• Files ending in .mjs.

• Files ending in .js when the nearest parent package.json file contains a top-level field "type" with a value of "module".
• Strings passed in as an argument to --eval or --print, or piped to node via STDIN, with the flag --input-type=module.

Once you have it setup, you can use import and export.

Using the example above, there are two approaches you can take

./sourceFile.js:

// This is a named export of variableName
export const variableName = 'variableValue'
// Alternatively, you could have exported it as a default. 
// For sake of explanation, I'm wrapping the variable in an object
// but it is not necessary. 
// You can actually omit declaring what variableName is here. 
// { variableName } is equivalent to { variableName: variableName } in this case. 
export default { variableName: variableName } 

./consumer.js:

// There are three ways of importing. 
// If you need access to a non-default export, then 
// you use { nameOfExportedVariable } 
import { variableName } from './sourceFile'
console.log(variableName) // 'variableValue'

// Otherwise, you simply provide a local variable name 
// for what was exported as default.
import sourceFile from './sourceFile'
console.log(sourceFile.variableName) // 'variableValue'

./sourceFileWithoutDefault.js:

// The third way of importing is for situations where there
// isn't a default export but you want to warehouse everything
// under a single variable. Say you have:
export const a = 'A'
export const b = 'B'

./consumer2.js

// Then you can import all exports under a single variable
// with the usage of * as:
import * as sourceFileWithoutDefault from './sourceFileWithoutDefault'

console.log(sourceFileWithoutDefault.a) // 'A'
console.log(sourceFileWithoutDefault.b) // 'B'

// You can use this approach even if there is a default export:
import * as sourceFile from './sourceFile'

// Default exports are under the variable default:
console.log(sourceFile.default) // { variableName: 'variableValue' }

// As well as named exports:
console.log(sourceFile.variableName) // 'variableValue

If a dedicated script seems like too much overhead, you can spawn separate processes explicitly with sh -c. For example:

CMD sh -c 'mini_httpd -C /my/config -D &' \
 && ./content_computing_loop

For "zip" files, you can use import zipfile and your code will be working simply with these lines:

import zipfile
import pandas as pd
with zipfile.ZipFile("Crime_Incidents_in_2013.zip") as z:
   with z.open("Crime_Incidents_in_2013.csv") as f:
      train = pd.read_csv(f, header=0, delimiter="\t")
      print(train.head())    # print the first 5 rows

And the result will be:

If you are using server side code like Java then you need to return active tab name and on return page have some function to disable( meaning remove active class) all tabs except the one you returned.

This would require you to add id or name to each tab. Little bit more work :)

div.abc.xyz {
    /* rules go here */
}

... or simply:

.abc.xyz {
    /* rules go here */
}

If you are looking for a solution to your particular case, it would be:

Date date = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'").parse("2012-05-20T09:00:00.000Z");
String formattedDate = new SimpleDateFormat("dd/MM/yyyy, Ka").format(date);

    for(int i=0; i<5; i++)
        v1.push_back(i*2);
    for(int i=0; i<v1.size(); i++)
        cout<<v1[i];    //02468
    reverse(v1.begin(),v1.end());
    
    for(int i=0; i<v1.size(); i++)

An update of Mogsdad's solution:

    var Avals = ss.getRange("A1:A").getValues();
    var Alast = Avals.filter(function(r){return r[0].length>0});

Simply outputting something is PowerShell is a thing of beauty - and one its greatest strengths. For example, the common Hello, World! application is reduced to a single line:

"Hello, World!"

It creates a string object, assigns the aforementioned value, and being the last item on the command pipeline it calls the .toString() method and outputs the result to STDOUT (by default). A thing of beauty.

The other Write-* commands are specific to outputting the text to their associated streams, and have their place as such.

if it is a Spring boot App.

Spring Boot automatically detects index.html in public/static/webapp folder. If you have written any controller @Requestmapping("/") it will override the default feature and it will not show the index.html unless you type localhost:8080/index.html

I got a similar failure with SMTP whenever my client machine changes network connection (e.g., home vs. office network) and somehow restarting network service (or rebooting the machine) resolves the issue for me. Not sure if this would apply to your case, but just in case.

sudo /etc/init.d/networking restart   # for ubuntu

Say your column names are dynamic, you can create an empty row-named matrix and transform it to a data frame.

nms <- sample(LETTERS,sample(1:10))
as.data.frame(t(matrix(nrow=length(nms),ncol=0,dimnames=list(nms))))

If you still use OID, it would be better to remove the dependency on it, because in recent versions of Postgres it is no longer supported. This can stop (temporarily until you solve it) your migration from version 10 to 12 for example.

I don't understand why, over the course of eight years, no one has posted the easy answer. Rather than encode the file as base64, encode the json as a string. Then just decode the json on the server side.

In Javascript:

let formData = new FormData();
formData.append("file", myfile);
formData.append("myjson", JSON.stringify(myJsonObject));

POST it using Content-Type: multipart/form-data

On the server side, retrieve the file normally, and retrieve the json as a string. Convert the string to an object, which is usually one line of code no matter what programming language you use.

(Yes, it works great. Doing it in one of my apps.)

Please try below code :

public T? GetParsedOrDefaultValue<T>(string valueToParse) where T : struct, IComparable
{
 if(string.EmptyOrNull(valueToParse))return null;
  try
  {
     // return parsed value
     return (T) Convert.ChangeType(valueToParse, typeof(T));
  }
  catch(Exception)
  {
   //default as null value
   return null;
  }
 return null;
}

You can also use the RestSharp library for example

var userName = "myuser";
var password = "mypassword";
var host = "170.170.170.170:333";
var client = new RestClient("https://" + host + "/method1");            
client.Authenticator = new HttpBasicAuthenticator(userName, password);            
var request = new RestRequest(Method.POST); 
request.AddHeader("Accept", "application/json");
request.AddHeader("Cache-Control", "no-cache");
request.AddHeader("Content-Type", "application/json");            
request.AddParameter("application/json","{}",ParameterType.RequestBody);
IRestResponse response = client.Execute(request);

Try This :) I created my on model of count all results

in library_model

function count_all_results($column_name = array(),$where=array(), $table_name = array())
{
        $this->db->select($column_name);
        // If Where is not NULL
        if(!empty($where) && count($where) > 0 )
        {
            $this->db->where($where);
        }
        // Return Count Column
        return $this->db->count_all_results($table_name[0]);//table_name array sub 0
}

Your Controller will look like this

public function my_method()
{
  $data = array(
     $countall = $this->model->your_method_model()
  );
   $this->load->view('page',$data);
}

Then Simple Call The Library Model In Your Model

function your_method_model()
{
        return $this->library_model->count_all_results(
               ['id'],
               ['where],
               ['table name']
           );
}

its really help u to understand what is DFD

To answer the original question:

To change the XAMPP Apache server port here the procedure :

1. Choose a free port number

The default port used by Apache is 80.

Take a look to all your used ports with Netstat (integrated to XAMPP Control Panel).

Then you can see all used ports and here we see that the 80port is already used by System.

Choose a free port number (8012, for this exemple).

2. Edit the file "httpd.conf"

This file should be found in C:\xampp\apache\conf on Windows or in bin/apache for Linux.:

Listen 80
ServerName localhost:80

Replace them by:

Listen 8012
ServerName localhost:8012

Save the file.

Access to : http://localhost:8012 for check if it's work.

If not, you must to edit the http-ssl.conf file as explain in step 3 below. ?

3. Edit the file "http-ssl.conf"

This file should be found in C:\xampp\apache\conf\extra on Windows or see this link for Linux.

Locate the following lines:

Listen 443
<VirtualHost _default_:443>
ServerName localhost:443

Replace them by with a other port number (8013 for this example) :

Listen 8013
<VirtualHost _default_:8013>
ServerName localhost:8013

Save the file.

Restart the Apache Server.

Access to : http://localhost:8012 for check if it's work.

4. Configure XAMPP Apache server settings

If your want to access localhost without specify the port number in the URL
http://localhost instead of http://localhost:8012.

• Open Xampp Control Panel
• Go to Config ? Service and Port Settings ? Apache
• Replace the Main Port and SSL Port values ??with those chosen (e.g. 8012 and 8013).
• Save Service settings
• Save Configuration of Control Panel
• Restart the Apache Server It should work now.

4.1. Web browser configuration

If this configuration isn't hiding port number in URL it's because your web browser is not configured for. See : Tools ? Options ? General ? Connection Settings... will allow you to choose different ports or change proxy settings.

4.2. For the rare cases of ultimate bad luck

If step 4 and Web browser configuration are not working for you the only way to do this is to change back to 80, or to install a listener on port 80 (like a proxy) that redirects all your traffic to port 8012.

To answer your problem :

If you still have this message in Control Panel Console :

Apache Started [Port 80]

• Find location of xampp-control.exe file (probably in C:\xampp)
• Create a file XAMPP.INI in that directory (so XAMPP.ini and xampp-control.exe are in the same directory)

Put following lines in the XAMPP.INI file:

[PORTS]
apache = 8012

Now , you will always get:

Apache started [Port 8012]

Please note that, this is for display purpose only. It has no relation with your httpd.conf.

Because of % operator cannot apply to BigDecimal and int (i.e. 1) directly, so I am using the following snippet to check if the BigDecimal is an integer:

value.stripTrailingZeros().scale() <= 0

if (($value > 1 && $value < 10) || ($value > 20 && $value < 40))

Try this. It will work. jquery unload method is depreceted.

window.onbeforeunload = function(event) {
    event.returnValue = "Write something clever here..";
};

There are two primary contenders for python apps on Android

Chaquopy

https://chaquo.com/chaquopy/

This integrates with the Android build system, it provides a Python API for all android features. To quote the site "The complete Android API and user interface toolkit are directly at your disposal."

Beeware (Toga widget toolkit)

https://pybee.org/

This provides a multi target transpiler, supports many targets such as Android and iOS. It uses a generic widget toolkit (toga) that maps to the host interface calls.

Which One?

Both are active projects and their github accounts shows a fair amount of recent activity.

Beeware Toga like all widget libraries is good for getting the basics out to multiple platforms. If you have basic designs, and a desire to expand to other platforms this should work out well for you.

On the other hand, Chaquopy is a much more precise in its mapping of the python API to Android. It also allows you to mix in Java, useful if you want to use existing code from other resources. If you have strict design targets, and predominantly want to target Android this is a much better resource.

You have to parse the string as JSON (data[0] == "[" is an indication that data is actually a string, not an object):

data = $.parseJSON(data);
$.each(data, function(i, item) {
    alert(item);
});

Start in debug mode, run code with F5 to stop your console app, don't click on red cross but press CTRL-break and you'll hit all breakpoints in the end of your program.

If you posting form using ajax then you can not send image using $.ajax method, you have to use classic xmlHttpobject method for saving image, other alternative of it use submit type instead of button

To insert a sleep command you can use Thread.sleep(2000). So the code would be:

List<Integer> myCoords = new ArrayList<Integer>();
myCoords.add(10);
myCoords.add(20);
myCoords.add(30);
myCoords.add(40);
myCoords.add(50);
Iterator<Integer> myListIterator = someList.iterator(); 
while (myListIterator.hasNext()) {
    Integer coord = myListIterator.next();    
    System.out.println(coord);
    Thread.Sleep(2000);
}

This would output: 10 20 30 40 50

If you want the numbers after each other you could use: System.out.print(coord +" " ); and if you want to repeat the section you can put it in another while loop.

List<Integer> myCoords = new ArrayList<Integer>();
myCoords.add(10);
myCoords.add(20);
myCoords.add(30);
myCoords.add(40);
myCoords.add(50);
while(true)
    Iterator<Integer> myListIterator = someList.iterator(); 
    while (myListIterator.hasNext()) {
        Integer coord = myListIterator.next();    
        System.out.print(coord + " ");
        Thread.Sleep(2000);
    }
}

This would output: 10 20 30 40 50 10 20 30 40 50 ... and never stop until you kill the program.

Edit: You do have to put the sleep command in a try catch block

Adding to jelovirt's answer, you can use number() to convert the value to a number, then round(), floor(), or ceiling() to get a whole integer.

Example

<xsl:variable name="MyValAsText" select="'5.14'"/>
<xsl:value-of select="number($MyValAsText) * 2"/> <!-- This outputs 10.28 -->
<xsl:value-of select="floor($MyValAsText)"/> <!-- outputs 5 -->
<xsl:value-of select="ceiling($MyValAsText)"/> <!-- outputs 6 -->
<xsl:value-of select="round($MyValAsText)"/> <!-- outputs 5 -->

If you are using a screen with filters for example, and you want to set the background of the filter regarding if it was selected or not, you can do:

<TouchableOpacity style={this.props.venueFilters.includes('Bar')?styles.filterBtnActive:styles.filterBtn} onPress={()=>this.setFilter('Bar')}>
<Text numberOfLines={1}>
Bar
</Text>
</TouchableOpacity>

On which set filter is:

setVenueFilter(filter){
  var filters = this.props.venueFilters;
  filters.push(filter);
  console.log(filters.includes('Bar'), "Inclui Bar");
  this.setState(previousState => {
    return { updateFilter: !previousState.updateFilter };
  });
  this.props.setVenueFilter(filters);
}

PS: the function this.props.setVenueFilter(filters) is a redux action, and this.props.venueFilters is a redux state.

I solved the issue using

ln -s libncursesw.so.5  /lib/x86_64-linux-gnu/libncursesw.so.6

If you want to reload specific entities, with the DbContextApi, RX_DID_RX already gave you the answer.

If you want to reload / refresh all the entities you loaded:

If you are using Entity Framework 4.1+ (EF5, or EF 6 probably), DbContext API:

public void RefreshAll()
{
     foreach (var entity in ctx.ChangeTracker.Entries())
     {
           entity.Reload();
     }
}

If you are using entityFramework 4 (ObjectContext API):

public void RefreshAll()
{
     // Get all objects in statemanager with entityKey
     // (context.Refresh will throw an exception otherwise)
     var refreshableObjects = (from entry in context.ObjectStateManager.GetObjectStateEntries(EntityState.Deleted
                                               | EntityState.Modified
                                               | EntityState.Unchanged)
                                      where entry.EntityKey != null
                                      select entry.Entity);

     context.Refresh(RefreshMode.StoreWins, refreshableObjects);
}

Best advice anyway is, try to use a "short lived context" and you'll avoid this kind of problems.

I wrote a couple of articles on the matter:

https://christianarg.wordpress.com/2013/06/13/entityframework-refreshall-loaded-entities-from-database/

You are mixing code that was compiled with /MD (use DLL version of CRT) with code that was compiled with /MT (use static CRT library). That cannot work, all source code files must be compiled with the same setting. Given that you use libraries that were pre-compiled with /MD, almost always the correct setting, you must compile your own code with this setting as well.

Project + Properties, C/C++, Code Generation, Runtime Library.

Beware that these libraries were probably compiled with an earlier version of the CRT, msvcr100.dll is quite new. Not sure if that will cause trouble, you may have to prevent the linker from generating a manifest. You must also make sure to deploy the DLLs you need to the target machine, including msvcr100.dll

If you are using Sql Server 2005 you can use table valued functions. You can call these directly and pass paramters, whilst treating them as if they were tables.

For more info check out Table-Valued User-Defined Functions

dtypes is a Pandas Series. That means it contains index & values attributes. If you only need the column names:

headers = df.dtypes.index

it will return a list containing the column names of "df" dataframe.

Check out "View Rendered Source" chrome extension:

https://chrome.google.com/webstore/detail/view-rendered-source/ejgngohbdedoabanmclafpkoogegdpob/

I am not sure it's possible with an "automatic" variable. You can always declare one for yourself and increment it:

$letters = { 'A', 'B', 'C' }
$letters | % {$counter = 0}{...;$counter++}

Or use a for loop instead...

for ($counter=0; $counter -lt $letters.Length; $counter++){...}

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

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

Note that Get-ADUser defaults to using

 -SearchScope Subtree

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

An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again. If a negated pattern matches, this will override lower precedence patterns sources.

http://schacon.github.com/git/gitignore.html

*.json
!spec/*.json

len(nams) should be equal to n in your code. All indexes 0 <= i < n "exist".

Luke's description of the function results in these scenarios seems to be right on. I only wish to understand the root cause and the PowerShell product team would do something about the behavior. It seems to be quite common and has cost me too much debugging time.

To get around this issue I've been using global variables rather than returning and using the value from the function call.

Here's another question on the use of global variables: Setting a global PowerShell variable from a function where the global variable name is a variable passed to the function

byte[] bytes = File.ReadAllBytes(filename) 

or ...

var bytes = File.ReadAllBytes(filename) 

public class MainActivity extends Activity {

ImageView imgV;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    imgV= (ImageView) findViewById("your Image View Id");

    imgV.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
                imgV.setScaleType(ScaleType.FIT_XY);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
getSupportActionBar().hide();
            }
        }
    });

}
}

Here's making the indexes unusable without the file:

DECLARE
  CURSOR  usr_idxs IS select * from user_indexes;
  cur_idx  usr_idxs% ROWTYPE;
  v_sql  VARCHAR2(1024);

BEGIN
  OPEN usr_idxs;
  LOOP
    FETCH usr_idxs INTO cur_idx;
    EXIT WHEN NOT usr_idxs%FOUND;

    v_sql:= 'ALTER INDEX ' || cur_idx.index_name || ' UNUSABLE';
    EXECUTE IMMEDIATE v_sql;
  END LOOP;
  CLOSE usr_idxs;
END;

The rebuild would be similiar.

YOU HAVE TO BE CAREFUL when you initialize state from props in constructor. Even if props changed to new one, the state wouldn't be changed because mount never happen again. So getDerivedStateFromProps exists for that.

class FirstComponent extends React.Component {
    state = {
        description: ""
    };
    
    static getDerivedStateFromProps(nextProps, prevState) {
        if (prevState.description !== nextProps.description) {
          return { description: nextProps.description };
        }
    
        return null;
    }

    render() {
        const {state: {description}} = this;    

        return (
            <input type="text" value={description} /> 
        );
    }
}

Or use key props as a trigger to initialize:

class SecondComponent extends React.Component {
  state = {
    // initialize using props
  };
}

<SecondComponent key={something} ... />

In the code above, if something changed, then SecondComponent will re-mount as a new instance and state will be initialized by props.

It seems odd that this directory was not created at install - have you manually changed the path of the socket file in the my.cfg?

Have you tried simply creating this directory yourself, and restarting the service?

mkdir -p /var/run/mysqld
chown mysql:mysql /var/run/mysqld

Go to http://dev.mysql.com/downloads/connector/j and with in the dropdown select "Platform Independent" then it will show you the options to download tar.gz file or zip file.

Download zip file and extract it, with in that you will find mysql-connector-XXX.jar file

If you are using maven then you can add the dependency from the link http://mvnrepository.com/artifact/mysql/mysql-connector-java

Select the version you want to use and add the dependency in your pom.xml file

Grinn solution is great.

However it doesn't work for me when there are parent folder relative references in the url. i.e. url('../../images/car.png')

So, I slightly changed the Include method in order to resolve the paths for each regex match, allowing relative paths and also to optionally embed the images in the css.

I also changed the IF DEBUG to check BundleTable.EnableOptimizations instead of HttpContext.Current.IsDebuggingEnabled.

    public new Bundle Include(params string[] virtualPaths)
    {
        if (!BundleTable.EnableOptimizations)
        {
            // Debugging. Bundling will not occur so act normal and no one gets hurt. 
            base.Include(virtualPaths.ToArray());
            return this;
        }
        var bundlePaths = new List<string>();
        var server = HttpContext.Current.Server;
        var pattern = new Regex(@"url\s*\(\s*([""']?)([^:)]+)\1\s*\)", RegexOptions.IgnoreCase);
        foreach (var path in virtualPaths)
        {
            var contents = File.ReadAllText(server.MapPath(path));
            var matches = pattern.Matches(contents);
            // Ignore the file if no matches
            if (matches.Count == 0)
            {
                bundlePaths.Add(path);
                continue;
            }
            var bundlePath = (System.IO.Path.GetDirectoryName(path) ?? string.Empty).Replace(@"\", "/") + "/";
            var bundleUrlPath = VirtualPathUtility.ToAbsolute(bundlePath);
            var bundleFilePath = string.Format("{0}{1}.bundle{2}",
                                               bundlePath,
                                               System.IO.Path.GetFileNameWithoutExtension(path),
                                               System.IO.Path.GetExtension(path));
            // Transform the url (works with relative path to parent folder "../")
            contents = pattern.Replace(contents, m =>
            {
                var relativeUrl = m.Groups[2].Value;
                var urlReplace = GetUrlReplace(bundleUrlPath, relativeUrl, server);
                return string.Format("url({0}{1}{0})", m.Groups[1].Value, urlReplace);
            });
            File.WriteAllText(server.MapPath(bundleFilePath), contents);
            bundlePaths.Add(bundleFilePath);
        }
        base.Include(bundlePaths.ToArray());
        return this;
    }


    private string GetUrlReplace(string bundleUrlPath, string relativeUrl, HttpServerUtility server)
    {
        // Return the absolute uri
        Uri baseUri = new Uri("http://dummy.org");
        var absoluteUrl = new Uri(new Uri(baseUri, bundleUrlPath), relativeUrl).AbsolutePath;
        var localPath = server.MapPath(absoluteUrl);
        if (IsEmbedEnabled && File.Exists(localPath))
        {
            var fi = new FileInfo(localPath);
            if (fi.Length < 0x4000)
            {
                // Embed the image in uri
                string contentType = GetContentType(fi.Extension);
                if (null != contentType)
                {
                    var base64 = Convert.ToBase64String(File.ReadAllBytes(localPath));
                    // Return the serialized image
                    return string.Format("data:{0};base64,{1}", contentType, base64);
                }
            }
        }
        // Return the absolute uri 
        return absoluteUrl;
    }

Hope it helps, regards.

In Python 3.5, I tried to incorporate similar code without use of modules (e.g. sys, Biopy) other than what's built-in to stop the script and print an error message to my users. Here's my example:

## My example:
if "ATG" in my_DNA: 
    ## <Do something & proceed...>
else: 
    print("Start codon is missing! Check your DNA sequence!")
    exit() ## as most folks said above

Later on, I found it is more succinct to just throw an error:

## My example revised:
if "ATG" in my_DNA: 
    ## <Do something & proceed...>
else: 
    raise ValueError("Start codon is missing! Check your DNA sequence!")

I solved it by replacing

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

$document_root with C:\MyWebSite\www\

fastcgi_param SCRIPT_FILENAME C:\MyWebSite\www\$fastcgi_script_name;

Internally, Javascript strings are all Unicode (actually UCS-2, a subset of UTF-16).

If you're retrieving the JSON files separately via AJAX, then you only need to make sure that the JSON files are served with the correct Content-Type and charset: Content-Type: application/json; charset="utf-8"). If you do that, jQuery should already have interpreted them properly by the time you access the deserialized objects.

Could you post an example of the code you’re using to retrieve the JSON objects?

ALTER TABLE {TABLE NAME}
ALTER COLUMN {COLUMN NAME} SET DEFAULT '{DEFAULT VALUES}'

example :

ALTER TABLE RESULT
ALTER COLUMN STATUS SET DEFAULT 'FAIL'

Practical example:

Imagine that you are modelling something like an I2C bus (signals called SCL for clock and SDA for data), where the bus is tri-state and both nets have a weak pull-up. Your testbench should model the pull-up resistor on the PCB with a value of 'H'.

scl <= 'H'; -- Testbench resistor pullup

Your I2C master or slave devices can drive the bus to '1' or '0' or leave it alone by assigning a 'Z'

Assigning a '1' to the SCL net will cause an event to happen, because the value of SCL changed.

• If you have a line of code that relies on (scl'event and scl = '1'), then you'll get a false trigger.

• If you have a line of code that relies on rising_edge(scl), then you won't get a false trigger.

Continuing the example: you assign a '0' to SCL, then assign a 'Z'. The SCL net goes to '0', then back to 'H'.

Here, going from '1' to '0' isn't triggering either case, but going from '0' to 'H' will trigger a rising_edge(scl) condition (correct), but the (scl'event and scl = '1') case will miss it (incorrect).

General Recommenation:

Use rising_edge(clk) and falling_edge(clk) instead of clk'event for all code.

I wrote small function for myself that works recursively in Postgres 9.4. I had same problem (good they did solve some of this headache in Postgres 9.5). Anyway here is the function (I hope it works well for you):

CREATE OR REPLACE FUNCTION jsonb_update(val1 JSONB,val2 JSONB)
RETURNS JSONB AS $$
DECLARE
    result JSONB;
    v RECORD;
BEGIN
    IF jsonb_typeof(val2) = 'null'
    THEN 
        RETURN val1;
    END IF;

    result = val1;

    FOR v IN SELECT key, value FROM jsonb_each(val2) LOOP

        IF jsonb_typeof(val2->v.key) = 'object'
            THEN
                result = result || jsonb_build_object(v.key, jsonb_update(val1->v.key, val2->v.key));
            ELSE
                result = result || jsonb_build_object(v.key, v.value);
        END IF;
    END LOOP;

    RETURN result;
END;
$$ LANGUAGE plpgsql;

Here is sample use:

select jsonb_update('{"a":{"b":{"c":{"d":5,"dd":6},"cc":1}},"aaa":5}'::jsonb, '{"a":{"b":{"c":{"d":15}}},"aa":9}'::jsonb);
                            jsonb_update                             
---------------------------------------------------------------------
 {"a": {"b": {"c": {"d": 15, "dd": 6}, "cc": 1}}, "aa": 9, "aaa": 5}
(1 row)

As you can see it analyze deep down and update/add values where needed.

$('.select_continent').click(function () {
    alert($(this).attr('value'));
});

The simplest way is: HTML:

<header>
        <h1>Website</h1>
</header>

CSS:

header{
    position: sticky;
    top: 0;
}

Try this:

git checkout -- main/dontcheckmein.txt

you can just declare the variable outside the outer class. After this, you will be able to edit the variable from within the inner class. I sometimes face similar problems while coding in android so I declare the variable as global and it works for me.

The problem could also be that Apache can't find php.ini If you set PHPIniDir incorrectly. Mine was set to: PHPIniDir "c:/php7" But, the folder is actually just "php" The clue was viewing phpinfo() Which showed: Configuration File (php.ini) Path C:\windows

Your struct is called struct xyx but a is of type struct xyz. Once you fix that, the output is 100.

Encapsulation is used for 2 main reasons:

1.) Data hiding & protecting (the user of your class can't modify the data except through your provided methods).

2.) Combining the data and methods used to manipulate the data together into one entity (capsule). I think that the second reason is the answer your interviewer wanted to hear.

On the other hand, abstraction is needed to expose only the needed information to the user, and hiding unneeded details (for example, hiding the implementation of methods, so that the user is not affected if the implementation is changed).

There's one more subtlety that can help here.

I want to have links that both allow in-browser playing and display as well as one for purely downloading. The new download attribute is fine, but doesn't work all the time because the browser's compulsion to play the or display the file is still very strong.

BUT.. this is based on examining the extension on the URL's filename!You don't want to fiddle with the server's extension mapping because you want to deliver the same file two different ways. So for the download, you can fool it by softlinking the file to a name that is opaque to this extension mapping, pointing to it, and then using download's rename feature to fix the name.

<a target="_blank" download="realname.mp3" href="realname.UNKNOWN">Download it</a>_x000D_
<a target="_blank" href="realname.mp3">Play it</a>

I was hoping just throwing a dummy query on the end or otherwise obfuscating the extension would work, but sadly, it doesn't.

WWW FAQs: What is the maximum length of a URL? has its own answer based on empirical testing and research. The short answer is that going over 2048 characters makes Internet Explorer unhappy and thus this is the limit you should use. See the page for a long answer.

You can also use OrderedDict:

In [183]: from collections import OrderedDict

In [184]: data = OrderedDict()

In [185]: data['one thing'] = [1,2,3,4]

In [186]: data['second thing'] = [0.1,0.2,1,2]

In [187]: data['other thing'] = ['a','e','i','o']

In [188]: frame = pd.DataFrame(data)

In [189]: frame
Out[189]:
   one thing  second thing other thing

Query_string

(Following is the text of the linked section of the Wikipedia entry.)

Structure

A typical URL containing a query string is as follows:

http://server/path/program?query_string

When a server receives a request for such a page, it runs a program (if configured to do so), passing the query_string unchanged to the program. The question mark is used as a separator and is not part of the query string.

A link in a web page may have a URL that contains a query string, however, HTML defines three ways a web browser can generate the query string:

• a web form via the ... element
• a server-side image map via the ?ismap? attribute on the element with a construction
• an indexed search via the now deprecated element

Web forms

The main use of query strings is to contain the content of an HTML form, also known as web form. In particular, when a form containing the fields field1, field2, field3 is submitted, the content of the fields is encoded as a query string as follows:

field1=value1&field2=value2&field3=value3...

• The query string is composed of a series of field-value pairs.
• Within each pair, the field name and value are separated by an equals sign. The equals sign may be omitted if the value is an empty string.
• The series of pairs is separated by the ampersand, '&' (or semicolon, ';' for URLs embedded in HTML and not generated by a ...; see below). While there is no definitive standard, most web frameworks allow multiple values to be associated with a single field:

field1=value1&field1=value2&field1=value3...

For each field of the form, the query string contains a pair field=value. Web forms may include fields that are not visible to the user; these fields are included in the query string when the form is submitted

This convention is a W3C recommendation. W3C recommends that all web servers support semicolon separators in addition to ampersand separators[6] to allow application/x-www-form-urlencoded query strings in URLs within HTML documents without having to entity escape ampersands.

Technically, the form content is only encoded as a query string when the form submission method is GET. The same encoding is used by default when the submission method is POST, but the result is not sent as a query string, that is, is not added to the action URL of the form. Rather, the string is sent as the body of the HTTP request.

If you are using Oracle 10g, you can use the DECODE function to pivot the rows into columns:

CREATE TABLE doc_tab (
  loan_number VARCHAR2(20),
  document_type VARCHAR2(20),
  document_id VARCHAR2(20)
);

INSERT INTO doc_tab VALUES('992452533663', 'Voters ID', 'XPD0355636');
INSERT INTO doc_tab VALUES('992452533663', 'Pan card', 'CHXPS5522D');
INSERT INTO doc_tab VALUES('992452533663', 'Drivers licence', 'DL-0420110141769');

COMMIT;

SELECT
    loan_number,
    MAX(DECODE(document_type, 'Voters ID', document_id)) AS voters_id,
    MAX(DECODE(document_type, 'Pan card', document_id)) AS pan_card,
    MAX(DECODE(document_type, 'Drivers licence', document_id)) AS drivers_licence
  FROM
    doc_tab
GROUP BY loan_number
ORDER BY loan_number;

Output:

LOAN_NUMBER   VOTERS_ID            PAN_CARD             DRIVERS_LICENCE    
------------- -------------------- -------------------- --------------------
992452533663  XPD0355636           CHXPS5522D           DL-0420110141769     

You can achieve the same using Oracle PIVOT clause, introduced in 11g:

SELECT *
  FROM doc_tab
PIVOT (
  MAX(document_id) FOR document_type IN ('Voters ID','Pan card','Drivers licence')
);

This is a quite confusing way of using Apache configuration directives.

Technically, the first bit is equivalent to

Allow From All

This is because Order Deny,Allow makes the Deny directive evaluated before the Allow Directives. In this case, Deny and Allow conflict with each other, but Allow, being the last evaluated will match any user, and access will be granted.

Now, just to make things clear, this kind of configuration is BAD and should be avoided at all cost, because it borders undefined behaviour.

The Limit sections define which HTTP methods have access to the directory containing the .htaccess file.

Here, GET and POST methods are allowed access, and PUT and DELETE methods are denied access. Here's a link explaining what the various HTTP methods are: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html

However, it's more than often useless to use these limitations as long as you don't have custom CGI scripts or Apache modules that directly handle the non-standard methods (PUT and DELETE), since by default, Apache does not handle them at all.

It must also be noted that a few other methods exist that can also be handled by Limit, namely CONNECT, OPTIONS, PATCH, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.

The last bit is also most certainly useless, since any correctly configured Apache installation contains the following piece of configuration (for Apache 2.2 and earlier):

#
# The following lines prevent .htaccess and .htpasswd files from being 
# viewed by Web clients. 
#
<Files ~ "^\.ht">
    Order allow,deny
    Deny from all
    Satisfy all
</Files>

which forbids access to any file beginning by ".ht".

The equivalent Apache 2.4 configuration should look like:

<Files ~ "^\.ht">
    Require all denied
</Files>

Ping is meant to be sent only from server to client, and browser should answer as soon as possible with Pong OpCode, automatically. So you have not to worry about that on higher level.

Although that not all browsers support standard as they suppose to, they might have some differences in implementing such mechanism, and it might even means there is no Pong response functionality. But personally I am using Ping / Pong, and never saw client that does not implement this type of OpCode and automatic response on low level client side implementation.

I have been working on a solution to this issue as none of the above answers really helped me. I am working with the jquery week calendar and needed my dates to have time zone information on the server and locally on the page. After quite a bit of digging around, I figured out a solution that may help others.

I am using asp.net 3.5, vs 2008, asp.net MVC 2, and jquery week calendar,

First, I am using a library written by Steven Levithan that helps with dealing with dates on the client side, Steven Levithan's date library. The isoUtcDateTime format is perfect for what I needed. In my jquery AJAX call I use the format function provided with the library with the isoUtcDateTime format and when the ajax call hits my action method, the datetime Kind is set to local and reflects the server time.

When I send dates to my page via AJAX, I send them as text strings by formatting the dates using "ddd, dd MMM yyyy HH':'mm':'ss 'GMT'zzzz". This format is easily converted client side using

var myDate = new Date(myReceivedDate);

Here is my complete solution minus Steve Levithan's source, which you can download:

Controller:

public class HomeController : Controller
{
    public const string DATE_FORMAT = "ddd, dd MMM yyyy HH':'mm':'ss 'GMT'zzzz";

    public ActionResult Index()
    {
        ViewData["Message"] = "Welcome to ASP.NET MVC!";

        return View();
    }

    public ActionResult About()
    {
        return View();
    }


    public JsonResult GetData()
    {
        DateTime myDate = DateTime.Now.ToLocalTime();

        return new JsonResult { Data = new { myDate = myDate.ToString(DATE_FORMAT) } };
    }

    public JsonResult ReceiveData(DateTime myDate)
    {
        return new JsonResult { Data = new { myDate = myDate.ToString(DATE_FORMAT) } };
    }
}

Javascript:

<script type="text/javascript">

function getData() {
    $.ajax({
        url: "/Home/GetData",
        type: "POST",
        cache: "false",
        dataType: "json",
        success: function(data) {
            alert(data.myDate);
            var newDate = cleanDate(data.myDate);
            alert(newDate);
            sendData(newDate);
        }
    });
} 

function cleanDate(d) {
    if (typeof d == 'string') {
        return new Date(d) || Date.parse(d) || new Date(parseInt(d));
    }
    if (typeof d == 'number') {
        return new Date(d);
    }
    return d;
}

function sendData(newDate) {
    $.ajax({
        url: "/Home/ReceiveData",
        type: "POST",
        cache: "false",
        dataType: "json",
        data:
        {
            myDate: newDate.format("isoUtcDateTime")
        },
        success: function(data) {
            alert(data.myDate);
            var newDate = cleanDate(data.myDate);
            alert(newDate);
        }
    });
}

// bind myButton click event to call getData
$(document).ready(function() {
    $('input#myButton').bind('click', getData);
});
</script>

I hope this quick example helps out others in the same situation I was in. At this time it seems to work very well with the Microsoft JSON Serialization and keeps my dates correct across timezones.

Find:

^[#;].*

Replace with nothing. The ^ indicates the start of a line, the [#;] is a character class to match either # or ;, and .* matches anything else in the line.

In versions of Notepad++ before 6.0, you won't be able to actually remove the lines due to a limitation in its regex engine; the replacement results in blank lines for each line matched. In other words, this:

# foo
; bar
statement;

Will turn into:

statement;

However, the replacement will work in Notepad++ 6.0 if you add \r, \n or \r\n to the end of the pattern, depending on which line ending your file is using, resulting in:

statement;

try

<div style="width:100%;">
    <div style="width:50px; float: left;"><img src="myleftimage" /></div>
    <div style="width:50px; float: right;"><img src="myrightimage" /></div>
    <div style="display:block; margin-left:auto; margin-right: auto;">Content Goes Here</div>
</div>

or

<div style="width:100%; border:2px solid #dadada;">
    <div style="width:50px; float: left;"><img src="myleftimage" /></div>
    <div style="width:50px; float: right;"><img src="myrightimage" /></div>
    <div style="display:block; margin-left:auto; margin-right: auto;">Content Goes Here</div>
<div style="clear:both"></div>    
</div>

you need to forward declare the name of the class if you don't want a header:

class ClassTwo;

Important: This only works in some cases, see Als's answer for more information..

Using jQuery it is very simple assuming the URL you wish to post to is on the same server or has implemented CORS

$(function() {
  $("#employeeLink").on("click",function(e) {
    e.preventDefault(); // cancel the link itself
    $.post(this.href,function(data) {
      $("#someContainer").html(data);
    });
  });
});

If you insist on using frames which I strongly discourage, have a form and submit it with the link

<form action="employee.action" method="post" target="myFrame" id="myForm"></form>

and use (in plain JS)

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the link
     document.getElementById("myForm").submit(); // but make sure nothing has name or ID="submit"
   });
 });

Without a form we need to make one

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the actual link
     var myForm = document.createElement("form");
     myForm.action=this.href;// the href of the link
     myForm.target="myFrame";
     myForm.method="POST";
     myForm.submit();
   });
 });

the easiest way would to use the eclipse IDE itself. Go to the menu and set build path. Make it point to the JAVA JDK and JRE file path in your directory. afterwards you can check the build path where compiled files are going to be set. in the bin folder by default though. The best thing would be to allow eclipse to handle itself the build path and only to edit it similar to the solution that is given above

MATLAB is a popular and widely adapted piece of a sophisticated software package. It'd be a mistake to think it's merely a math software since it has a wide range of "toolboxes". I recently used Matplotlib to plot some data from a database and it did the job without needing all the bells and whistles of MATLAB. However, it may not be proper to compare Python and MATLAB in every situation. As with everything else the decision depends on what you need to do.

I used MATLAB in undergrad for control systems design and simulation and also for image processing in grad school. For these fields MATLAB makes the most sense because of the powerful control and image processing toolboxes. As everyone mentioned, array operations, which are used in every MATLAB script you'd need to write, are very easy with MATLAB.

Another nice thing about MATLAB is that it's very easy and fast to do prototyping and trying out ideas using the built in toolbox functions. For instance, it takes no effort to import an image and compute it's histogram or do some simple processing on it. One disadvantage of MATLAB could be it's speed because of its interpreted nature. However, if one really needs speed than he can choose to implement the tested logic in C/C++, etc.

For further comparison with Python, I can say that MATLAB provides a full package for you to do your work without the need of looking around for external libraries and implementing extra functions.

One last point about MATLAB which I see is not mentioned in the answers here is that it has a very powerful visual modeling/simulation environment called Simulink. It's easier to design and simulate larger systems with Simulink.

Finally, again, it all depends on the problem you need to solve. If your problem domain can make use of one of MATLAB's toolboxes and you have access to MATLAB then you can be sure that you'll have the right tool to solve it.

FragmentActivity is part of the support library, while Activity is the framework's default class. They are functionally equivalent.

You should always use FragmentActivity and android.support.v4.app.Fragment instead of the platform default Activity and android.app.Fragment classes. Using the platform defaults mean that you are relying on whatever implementation of fragments is used in the device you are running on. These are often multiple years old, and contain bugs that have since been fixed in the support library.

Most debugger consoles support displaying objects directly. Just use

console.log(obj);

Depending on your debugger this most likely will display the object in the console as a collapsed tree. You can open the tree and inspect the object.

In the Terms of Service of google we can read:

5.3 You agree not to access (or attempt to access) any of the Services by any means other than through the interface that is provided by Google, unless you have been specifically allowed to do so in a separate agreement with Google. You specifically agree not to access (or attempt to access) any of the Services through any automated means (including use of scripts or web crawlers) and shall ensure that you comply with the instructions set out in any robots.txt file present on the Services.

So I guess the answer is No. More over the SOAP API is no longer available

@mrcheif I found this answer today and it was very useful although it did return a wrong IP (not due to the code not working) but it gave the wrong internetwork IP when you have such things as Himachi running.

public static string localIPAddress()
{
    IPHostEntry host;
    string localIP = "";
    host = Dns.GetHostEntry(Dns.GetHostName());

    foreach (IPAddress ip in host.AddressList)
    {
        localIP = ip.ToString();

        string[] temp = localIP.Split('.');

        if (ip.AddressFamily == AddressFamily.InterNetwork && temp[0] == "192")
        {
            break;
        }
        else
        {
            localIP = null;
        }
    }

    return localIP;
}

Short Answer:

lower-cased words with a hyphen as separator

Long Answer:

What is the purpose of a URL?

If pointing to an address is the answer, then a shortened URL is also doing a good job. If we don't make it easy to read and maintain, it won't help developers and maintainers alike. They represent an entity on the server, so they must be named logically.

Google recommends using hyphens

Consider using punctuation in your URLs. The URL http://www.example.com/green-dress.html is much more useful to us than http://www.example.com/greendress.html. We recommend that you use hyphens (-) instead of underscores (_) in your URLs.

Coming from a programming background, camelCase is a popular choice for naming joint words.

But RFC 3986 defines URLs as case-sensitive for different parts of the URL. Since URLs are case sensitive, keeping it low-key (lower cased) is always safe and considered a good standard. Now that takes a camel case out of the window.

No need for two cron entries, you can put it into one with:

* * * * * /bin/bash -l -c "/path/to/executable; sleep 30 ; /path/to/executable"

so in your case:

* * * * * /bin/bash -l -c "cd /srv/last_song/releases/20120308133159 && script/rails runner -e production '\''Song.insert_latest'\'' ; sleep 30 ; cd /srv/last_song/releases/20120308133159 && script/rails runner -e production '\''Song.insert_latest'\''"

Working example. Notes below.

class Animal {
    constructor(public name) {
    }

    move(meters) {
        alert(this.name + " moved " + meters + "m.");
    }
}

class Snake extends Animal {
    move() {
        alert(this.name + " is Slithering...");
        super.move(5);
    }
}

class Horse extends Animal {
    move() {
        alert(this.name + " is Galloping...");
        super.move(45);
    }
}

var sam = new Snake("Sammy the Python");
var tom: Animal = new Horse("Tommy the Palomino");

sam.move();
tom.move(34);

1. You don't need to manually assign the name to a public variable. Using public name in the constructor definition does this for you.

2. You don't need to call super(name) from the specialised classes.

3. Using this.name works.

Notes on use of super.

This is covered in more detail in section 4.9.2 of the language specification.

The behaviour of the classes inheriting from Animal is not dissimilar to the behaviour in other languages. You need to specify the super keyword in order to avoid confusion between a specialised function and the base class function. For example, if you called move() or this.move() you would be dealing with the specialised Snake or Horse function, so using super.move() explicitly calls the base class function.

There is no confusion of properties, as they are the properties of the instance. There is no difference between super.name and this.name - there is simply this.name. Otherwise you could create a Horse that had different names depending on whether you were in the specialized class or the base class.

In Rails 4 you could do:

GroupMember.find_or_create_by(member_id: 4, group_id: 7)

And use where is different:

GroupMember.where(member_id: 4, group_id: 7).first_or_create

This will call create on GroupMember.where(member_id: 4, group_id: 7):

GroupMember.where(member_id: 4, group_id: 7).create

On the contrary, the find_or_create_by(member_id: 4, group_id: 7) will call create on GroupMember:

GroupMember.create(member_id: 4, group_id: 7)

Please see this relevant commit on rails/rails.

You can use .html() to get content of span and or div elements.

example:

    var monthname =  $(this).html();
    alert(monthname);

Font myFont = new Font("Serif", Font.BOLD, 12);, then use a setFont method on your components like

JButton b = new JButton("Hello World");
b.setFont(myFont);

Be careful while adding a property to the existing object using .(dot) method.

(.dot) method of adding a property to the object should only be used if you know the 'key' beforehand otherwise use the [bracket] method.

Example:

   var data = {_x000D_
        'Property1': 1_x000D_
    };_x000D_
    _x000D_
    // Two methods of adding a new property [ key (Property4), value (4) ] to the_x000D_
    // existing object (data)_x000D_
    data['Property2'] = 2; // bracket method_x000D_
    data.Property3 = 3;    // dot method_x000D_
    console.log(data);     // { Property1: 1, Property2: 2, Property3: 3 }_x000D_
    _x000D_
    // But if 'key' of a property is unknown and will be found / calculated_x000D_
    // dynamically then use only [bracket] method not a dot method    _x000D_
    var key;_x000D_
    for(var i = 4; i < 6; ++i) {_x000D_
     key = 'Property' + i;     // Key - dynamically calculated_x000D_
     data[key] = i; // CORRECT !!!!_x000D_
    }_x000D_
    console.log(data); _x000D_
    // { Property1: 1, Property2: 2, Property3: 3, Property4: 4, Property5: 5 }_x000D_
    _x000D_
    for(var i = 6; i < 2000; ++i) {_x000D_
     key = 'Property' + i; // Key - dynamically calculated_x000D_
     data.key = i;         // WRONG !!!!!_x000D_
    }_x000D_
    console.log(data); _x000D_
    // { Property1: 1, Property2: 2, Property3: 3, _x000D_
    //   Property4: 4, Property5: 5, key: 1999 }

Note the problem in the end of console log - 'key: 1999' instead of Property6: 6, Property7: 7,.........,Property1999: 1999. So the best way of adding dynamically created property is the [bracket] method.

Another NS lookup utility that can be used for reversed lookup is dig with the -x option:

$ dig -x 72.51.34.34

; <<>> DiG 9.9.2-P1 <<>> -x 72.51.34.34

Quoting from the dig manpage:

Reverse lookups -- mapping addresses to names -- are simplified by the -x option. addr is an IPv4 address in dotted-decimal notation, or a colon-delimited IPv6 address. When this option is used, there is no need to provide the name, class and type arguments. dig automatically performs a lookup for a name like 11.12.13.10.in-addr.arpa and sets the query type and class to PTR and IN respectively.

I think the following function can help to have scroll coordinate values:

const getScrollCoordinate = (el = window) => ({
  x: el.pageXOffset || el.scrollLeft,
  y: el.pageYOffset || el.scrollTop,
});

I got this idea from this answer with a little change.

The below function is most efficient way to deep clone javascript objects.

function deepCopy(obj){
    if (!obj || typeof obj !== "object") return obj;

    var retObj = {};

    for (var attr in obj){
        var type = obj[attr];

        switch(true){
            case (type instanceof Date):
                var _d = new Date();
                _d.setDate(type.getDate())
                retObj[attr]= _d;
                break;

            case (type instanceof Function):
                retObj[attr]= obj[attr];
                break;

            case (type instanceof Array):
                var _a =[];
                for (var e of type){
                    //_a.push(e);
                    _a.push(deepCopy(e));
                }
                retObj[attr]= _a;
                break;

            case (type instanceof Object):
                var _o ={};
                for (var e in type){
                    //_o[e] = type[e];
                    _o[e] = deepCopy(type[e]);
                }
                retObj[attr]= _o;
                break;

            default:
                retObj[attr]= obj[attr];
        }
    }
    return retObj;
}

var obj = {
    string: 'test',
    array: ['1'],
    date: new Date(),
    object:{c: 2, d:{e: 3}},
    function: function(){
        return this.date;
    }
};

var copyObj = deepCopy(obj);

console.log('object comparison', copyObj === obj); //false
console.log('string check', copyObj.string === obj.string); //true
console.log('array check', copyObj.array === obj.array); //false
console.log('date check', copyObj2.date === obj.date); //false
console.log('object check', copyObj.object === obj.object); //false
console.log('function check', copyObj.function() === obj.function()); //true

Another solution is to build an associative array with date format and then reformat data.

This method is useful for date formatted in an unussual way.

An example:

    mydate='01.02.12 10:20:43':
    myformat='dd/mm/yy HH:MM:ss';


    dtsplit=mydate.split(/[\/ .:]/);
    dfsplit=myformat.split(/[\/ .:]/);

    // creates assoc array for date
    df = new Array();
    for(dc=0;dc<6;dc++) {
            df[dfsplit[dc]]=dtsplit[dc];
            }

    // uses assc array for standard mysql format
    dstring[r] = '20'+df['yy']+'-'+df['mm']+'-'+df['dd'];
    dstring[r] += ' '+df['HH']+':'+df['MM']+':'+df['ss'];
