You can use getEventListeners in your Google Chrome developer console.

getEventListeners(object) returns the event listeners registered on the specified object.

getEventListeners(document.querySelector('option[value=Closed]'));

Looks like the mysql server is not started.

Look to the official documentation of MySQL how you can start a service under windows.

Install the server as a service using this command: C:> "C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqld" --install

This one is similar to @Wilhelm's solution. The loop automates based on a range created by evaluating the populated date column. This was slapped together based strictly on the conversation here and screenshots.

Please note: This assumes that the headers will always be on the same row (row 8). Changing the first row of data (moving the header up/down) will cause the range automation to break unless you edit the range block to take in the header row dynamically. Other assumptions include that VOL and CAPACITY formula column headers are named "Vol" and "Cap" respectively.

Sub Loop3()

Dim dtCnt As Long
Dim rng As Range
Dim frmlas() As String

Application.ScreenUpdating = False

'The following code block sets up the formula output range
dtCnt = Sheets("Loop").Range("A1048576").End(xlUp).Row              'lowest date column populated
endHead = Sheets("Loop").Range("XFD8").End(xlToLeft).Column         'right most header populated
Set rng = Sheets("Loop").Range(Cells(9, 2), Cells(dtCnt, endHead))  'assigns range for automation

ReDim frmlas(1)      'array assigned to formula strings
    'VOL column formula
frmlas(0) = "VOL FORMULA"
    'CAPACITY column formula
frmlas(1) = "CAP FORMULA"

For i = 1 To rng.Columns.count
If rng(0, i).Value = "Vol" Then         'checks for volume formula column
    For j = 1 To rng.Rows.count
        rng(j, i).Formula= frmlas(0)    'inserts volume formula
    Next j
ElseIf rng(0, i).Value = "Cap" Then     'checks for capacity formula column
    For j = 1 To rng.Rows.count
        rng(j, i).Formula = frmlas(1)   'inserts capacity formula
    Next j
End If
Next i

Application.ScreenUpdating = True

End Sub

I've located a solution that worked better for me, and which has the advantage of being usable with several images (case not illustrated in this example).

From @adeneo's answer on this question :

If you have an element with a background image, like this

<div id="test" style="background-image: url(link/to/image.png)"><div>

You can wait for the background to load by getting the image URL and using it for an image object in javascript with an onload handler

var src = $('#test').css('background-image');
var url = src.match(/\((.*?)\)/)[1].replace(/('|")/g,'');

var img = new Image();
img.onload = function() {
    alert('image loaded');
}
img.src = url;
if (img.complete) img.onload();

With ASP.NET 5 there is no Request variable available anymore. You can access it now with Context.Request

Also there is no IsAjaxRequest() Method anymore, you have to write it by yourself, for example in Extensions\HttpRequestExtensions.cs

using System;
using Microsoft.AspNetCore.Http;

namespace Microsoft.AspNetCore.Mvc
{
    public static class HttpRequestExtensions
    {
        public static bool IsAjaxRequest(this HttpRequest request)
        {
            if (request == null)
            {
                throw new ArgumentNullException(nameof(request));
            }

            return (request.Headers != null) && (request.Headers["X-Requested-With"] == "XMLHttpRequest");
        }
    }
}

I searched for a while now on this and hope that will help some others too ;)

I'd be careful about trying to get too clever here. I think it's confusing as it is and using more advanced nth-child parameters will only make it more complicated. As for the background color I'd just set that to a variable.

Here goes what I came up with before I realized trying to be too clever might be a bad thing.

#romtest {
 $bg: #e5e5e5;
 .detailed {
    th {
      &:nth-child(-2n+6) {
        background-color: $bg;
      }
    }
    td {
      &:nth-child(3n), &:nth-child(2), &:nth-child(7) {
        background-color: $bg;
      }
      &.last {
        &:nth-child(-2n+4){
          background-color: $bg;
        }
      }
    }
  }
}

and here is a quick demo: http://codepen.io/anon/pen/BEImD

----EDIT----

Here's another approach to avoid retyping background-color:

#romtest {
  %highlight {
    background-color: #e5e5e5; 
  }
  .detailed {
    th {
      &:nth-child(-2n+6) {
        @extend %highlight;
      }
    }

    td {
      &:nth-child(3n), &:nth-child(2), &:nth-child(7) {
        @extend %highlight;
      }
      &.last {
        &:nth-child(-2n+4){
          @extend %highlight;
        }
      }
    }
  }
}

//backend.

@PostMapping("/")
public List<A> addList(@RequestBody A aObject){
//......ur code
}

class A{
int num;
String name;
List<B> bList;
//getters and setters and default constructor
}
class B{
int d;
//defalut Constructor & gettes&setters
}

// postman

{
"num":value,
"name":value,
"bList":[{
"key":"value",
"key":"value",.....
}]
}

1. the error is for list there is no default constructor .so we can keep our list of object as a property of another class and pass the list of objects through the postman as the parameter of the another class.

I discovered quite by accident (I was working with images at the time) that the box-shadow, border-radius and transitions work quite well with the bog-standard audio tag player. I have this working in Chrome, FF and Opera.

audio:hover, audio:focus, audio:active
{
-webkit-box-shadow: 15px 15px 20px rgba(0,0, 0, 0.4);
-moz-box-shadow: 15px 15px 20px rgba(0,0, 0, 0.4);
box-shadow: 15px 15px 20px rgba(0,0, 0, 0.4);
-webkit-transform: scale(1.05);
-moz-transform: scale(1.05);
transform: scale(1.05);
}

with:-

audio
{
-webkit-transition:all 0.5s linear;
-moz-transition:all 0.5s linear;
-o-transition:all 0.5s linear;
transition:all 0.5s linear;
-moz-box-shadow: 2px 2px 4px 0px #006773;
-webkit-box-shadow:  2px 2px 4px 0px #006773;
box-shadow: 2px 2px 4px 0px #006773;
-moz-border-radius:7px 7px 7px 7px ;
-webkit-border-radius:7px 7px 7px 7px ;
border-radius:7px 7px 7px 7px ;
}

I grant you it only "tarts it up a bit", but it makes them a sight more exciting than what's already there, and without doing MAJOR fannying about in JS.

NOT available in IE, unfortunately (not yet supporting the transition bit), but it seems to degrade nicely.

Your '/0' should be '\0' .. you got the slash reversed/leaning the wrong way. Your while should look like:

while (*(forward++)!='\0') 

though the != '\0' part of your expression is optional here since the loop will continue as long as it evaluates to non-zero (null is considered zero and will terminate the loop).

All "special" characters (i.e., escape sequences for non-printable characters) use a backward slash, such as tab '\t', or newline '\n', and the same for null '\0' so it's easy to remember.

In addition, you can build the binary package using the --binary option.

R CMD build --binary RJSONIO_0.2-3.tar.gz

If you look at this bug 224128, it appears that MergeSort is being used by Mozilla.

For .NET 2.0 you could implement a class which inherits from Dictionary and implements ICloneable.

public class CloneableDictionary<TKey, TValue> : Dictionary<TKey, TValue> where TValue : ICloneable
{
    public IDictionary<TKey, TValue> Clone()
    {
        CloneableDictionary<TKey, TValue> clone = new CloneableDictionary<TKey, TValue>();

        foreach (KeyValuePair<TKey, TValue> pair in this)
        {
            clone.Add(pair.Key, (TValue)pair.Value.Clone());
        }

        return clone;
    }
}

You can then clone the dictionary simply by calling the Clone method. Of course this implementation requires that the value type of the dictionary implements ICloneable, but otherwise a generic implementation isn't practical at all.

Thinking of a string as a set of characters, in mathematics the empty set is always a subset of any set.

Use @Deprecated on method. Don't forget about clarifying javadoc field:

/**
 * Does some thing in old style.
 *
 * @deprecated use {@link #new()} instead.  
 */
@Deprecated
public void old() {
// ...
}

There is a huge difference between a single static class instance (that is, a single instance of a class, which happens to be a static or global variable) and a single static pointer to an instance of the class on the heap:

When your application exits, the destructor of the static class instance will be called. That means if you used that static instance as a singleton, your singleton ceased working properly. If there is still code running that uses that singleton, for example in a different thread, that code is likely to crash.

Similarly in Java, you can create a S4 class in R that encapsulates your information:

setClass(Class="Person",
         representation(
            height="numeric",
            age="numeric"
          )
)

Then your function can return an instance of this class:

myFunction = function(age=28, height=176){
  return(new("Person",
          age=age,
          height=height))
}

and you can access your information:

aPerson = myFunction()

aPerson@age
aPerson@height

YUI has a testing framework as well. This video from Yahoo! Theater is a nice introduction, although there are a lot of basics about TDD up front.

This framework is generic and can be run against any JavaScript or JS library.

You could use Prototype's template system if you really feel like using a sledgehammer to crack a nut:

var template = new Template("I'm #{age} years old!");
alert(template.evaluate({age: 21}));

Try to use EventBus or ContentProvider like solution.

If you are in the same process(normally all your activities would be), try to use EventBus, cause in process data exchange does NOT need a somewhat buffer, so you do not need to worry about your data is too large. (You can just use method call to pass data indeed, and EventBus hide the ugly things) Here is the detail:

// one side
startActivity(intentNotTooLarge);
EventBus.getDefault().post(new FooEvent(theHugeData));

// the other side
@Subscribe public void handleData(FooEvent event) { /* get and handle data */ }

If the two sides of Intent are not in the same process, try somewhat ContentProvider.

See TransactionTooLargeException

The Binder transaction failed because it was too large.

During a remote procedure call, the arguments and the return value of the call are transferred as Parcel objects stored in the Binder transaction buffer. If the arguments or the return value are too large to fit in the transaction buffer, then the call will fail and TransactionTooLargeException will be thrown.

I had trouble getting this to work and added another solution for anyone wanting/ needing to use FromCollection.

Instead of:

@Html.CheckBoxFor(model => true, item.TemplateId) 

Format html helper like so:

@Html.CheckBoxFor(model => model.SomeProperty, new { @class = "form-control", Name = "SomeProperty"})

Then in the viewmodel/model wherever your logic is:

public void Save(FormCollection frm)
{   
    // to do instantiate object.

    instantiatedItem.SomeProperty = (frm["SomeProperty"] ?? "").Equals("true", StringComparison.CurrentCultureIgnoreCase);

    // to do and save changes in database.
}

What about this?

{ git symbolic-ref HEAD 2> /dev/null || git rev-parse --short HEAD 2> /dev/null } | sed "s#refs/heads/##"

I had the same problem, but nothing above worked...try a really simple solution...

Back up your .htaccess file. Delete it from your root directory. Then try accessing those directories. Its likely that whatever rewrite conditions you had in your file were causing those access issues. The index page should be picked up automatically on most hosts. :P

I had this issue using Vesta CP and for me, the trick was remove .htaccess and try to access to any file again.

That resulted on regeneration of .htaccess file and then I was able to access to my files.

I found this more useful for getting the absolute file location.

File file = new File("\\TestHello\\test.txt");
System.out.println(file.getAbsoluteFile());

In 12c, here's the new way:

select bla
  from bla
 where bla
 order by finaldate desc
 fetch first 1 rows only; 

How nice is that!

Adding onto Miguel Borges answer above you can give the user that green success feedback by adding the following line to in the highlight/unhighlight code block.

    highlight: function(element) {
        $(element).closest('.form-group').removeClass('has-success').addClass('has-error');
    },
    unhighlight: function(element) {
        $(element).closest('.form-group').removeClass('has-error').addClass('has-success');
    }

Passive event listeners are an emerging web standard, new feature shipped in Chrome 51 that provide a major potential boost to scroll performance. Chrome Release Notes.

It enables developers to opt-in to better scroll performance by eliminating the need for scrolling to block on touch and wheel event listeners.

Problem: All modern browsers have a threaded scrolling feature to permit scrolling to run smoothly even when expensive JavaScript is running, but this optimization is partially defeated by the need to wait for the results of any touchstart and touchmove handlers, which may prevent the scroll entirely by calling preventDefault() on the event.

Solution: {passive: true}

By marking a touch or wheel listener as passive, the developer is promising the handler won't call preventDefault to disable scrolling. This frees the browser up to respond to scrolling immediately without waiting for JavaScript, thus ensuring a reliably smooth scrolling experience for the user.

document.addEventListener("touchstart", function(e) {
    console.log(e.defaultPrevented);  // will be false
    e.preventDefault();   // does nothing since the listener is passive
    console.log(e.defaultPrevented);  // still false
}, Modernizr.passiveeventlisteners ? {passive: true} : false);

Your script contains errors as well, for example if you have dos2unix installed your install works but if you don't like I did then it will fail with dependency issues.

I found this by accident as I was making a script file of this to give to my friend who is new to Linux and because I made the scripts on windows I directed him to install it, at the time I did not have dos2unix installed thus I got errors.

here is a copy of the script I made for your solution but have dos2unix installed.

#!/bin/sh
echo "deb http://ftp.debian.org/debian sid main" >> /etc/apt/sources.list
apt-get update
apt-get -t sid install libc6 libc6-dev libc6-dbg
echo "Please remember to hash out sid main from your sources list. /etc/apt/sources.list"

this script has been tested on 3 machines with no errors.

Yes reinstall and select command line to get the svn in Program Files-> Tortoise SVN folder.

You can use str.isalpha().

For example:

s = 'a123b'

for char in s:
    print(char, char.isalpha())

Output:

a True
1 False
2 False
3 False
b True

Here's how we approach this:

public static int MonthDiff(DateTime date1, DateTime date2)
{
    if (date1.Month < date2.Month)
    {
        return (date2.Year - date1.Year) * 12 + date2.Month - date1.Month;
    }
    else
    {
        return (date2.Year - date1.Year - 1) * 12 + date2.Month - date1.Month + 12;
    }
}

As Ben said, you are POSTing your request ( HttpMethod.Post specified in your code )

The querystring (get) parameters included in your url probably will not do anything.

Try this:

string url = "http://myserver/method";    
string content = "param1=1&param2=2";
HttpClientHandler handler = new HttpClientHandler();
HttpClient httpClient = new HttpClient(handler);
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, url);
HttpResponseMessage response = await httpClient.SendAsync(request,content);

Instead of directly messing with innerHTML it might be better to create a fragment and then insert that:

function create(htmlStr) {
    var frag = document.createDocumentFragment(),
        temp = document.createElement('div');
    temp.innerHTML = htmlStr;
    while (temp.firstChild) {
        frag.appendChild(temp.firstChild);
    }
    return frag;
}

var fragment = create('<div>Hello!</div><p>...</p>');
// You can use native DOM methods to insert the fragment:
document.body.insertBefore(fragment, document.body.childNodes[0]);

Benefits:

1. You can use native DOM methods for insertion such as insertBefore, appendChild etc.
2. You have access to the actual DOM nodes before they're inserted; you can access the fragment's childNodes object.
3. Using document fragments is very quick; faster than creating elements outside of the DOM and in certain situations faster than innerHTML.

Even though innerHTML is used within the function, it's all happening outside of the DOM so it's much faster than you'd think...

To create a popup you'll need the following script:

<script language="javascript" type="text/javascript">

function popitup(url) {
newwindow=window.open(url,'name','height=200,width=150');
if (window.focus) {newwindow.focus()}
return false;
}


</script>

Then, you link to it by:

  <a href="popupex.html" onclick="return popitup('popupex.html')">Link to popup</a>

If you want you can call the function directly from document.ready also. Or maybe from another function.

Only two steps:

1. Install the latest release "pandoc" from here:

   https://github.com/jgm/pandoc/releases

2. Call the function pandoc in the library(knitr)

   library(knitr)
   pandoc('input.md', format = 'latex')
   

Thus, you can convert your "input.md" into "input.pdf".

Use this package vue-click-outside

It's simple and reliable, currently used by many other packages. You can also reduce your javascript bundle size by calling the package only in the required components (see example below).

npm install vue-click-outside

Usage :

<template>
  <div>
    <div v-click-outside="hide" @click="toggle">Toggle</div>
    <div v-show="opened">Popup item</div>
  </div>
</template>

<script>
import ClickOutside from 'vue-click-outside'

export default {
  data () {
    return {
      opened: false
    }
  },

  methods: {
    toggle () {
      this.opened = true
    },

    hide () {
      this.opened = false
    }
  },

  mounted () {
    // prevent click outside event with popupItem.
    this.popupItem = this.$el
  },

  // do not forget this section
  directives: {
    ClickOutside
  }
}
</script>

                datelist.Add((dateSt = dateSt.AddDays(1)));
            }
            if (nonWorkingDays == NonWorkingDays.SaturdaySunday)
            {
                return datelist.Count(d => d.DayOfWeek != DayOfWeek.Saturday &&
                       d.DayOfWeek != DayOfWeek.Friday);
            }

You have to update the php.ini config file with in your host provider's server, trust me on this, more than likely there is nothing wrong with your code. It took me almost a month and a half to realize that most hosting servers are not up to date on php.ini files, eg. php 5.5 or later, I believe.

How about

^[A-Za-z]\S*

a letter followed by 0 or more non-space characters (will include all special symbols).

There are a couple of tests using the URL constructor which do not delineate whether the input is a string or URL object.

// Testing whether something is a URL
function isURL(url) {
    return toString.call(url) === "[object URL]";
}

// Testing whether the input is both a string and valid url:
function isUrl(url) {
    try {
        return toString.call(url) === "[object String]" && !!(new URL(url));
    } catch (_) {
        return false;  
    }
}

String.Replace('\n', '') doesn't work because '' is not a valid character literal.

If you use the String.Replace(string, string) override, it should work.

string temp = mystring.Replace("\n", "");

I've written some code that provides "LINQ to HTML" functionality. I thought I would share it here. It is based on Majestic 12. It takes the Majestic-12 results and produces LINQ XML elements. At that point you can use all your LINQ to XML tools against the HTML. As an example:

        IEnumerable<XNode> auctionNodes = Majestic12ToXml.Majestic12ToXml.ConvertNodesToXml(byteArrayOfAuctionHtml);

        foreach (XElement anchorTag in auctionNodes.OfType<XElement>().DescendantsAndSelf("a")) {

            if (anchorTag.Attribute("href") == null)
                continue;

            Console.WriteLine(anchorTag.Attribute("href").Value);
        }

I wanted to use Majestic-12 because I know it has a lot of built-in knowledge with regards to HTML that is found in the wild. What I've found though is that to map the Majestic-12 results to something that LINQ will accept as XML requires additional work. The code I'm including does a lot of this cleansing, but as you use this you will find pages that are rejected. You'll need to fix up the code to address that. When an exception is thrown, check exception.Data["source"] as it is likely set to the HTML tag that caused the exception. Handling the HTML in a nice manner is at times not trivial...

So now that expectations are realistically low, here's the code :)

If this is because Web API 2 ran into a deserialization problem due to mismatched data types, it's possible to find out where it failed by inspecting the content stream. It will read up until it hits an error, so if you read the content as a string, you should have the back half of the data you posted:

string json = await Request.Content.ReadAsStringAsync();

Fix that parameter, and it should make it further next time (or succeed if you're lucky!)...

So I guess

Sheet1.Range("E2", "E3000").NumberFormat = "MMM dd yyyy"

would do the trick for you.

No, you cannot specify whether the stroke is drawn inside or outside an element. I made a proposal to the SVG working group for this functionality in 2003, but it received no support (or discussion).

As I noted in the proposal,

• you can achieve the same visual result as "inside" by doubling your stroke width and then using a clipping path to clip the object to itself, and
• you can achieve the same visual result as 'outside' by doubling the stroke width and then overlaying a no-stroke copy of the object on top of itself.

Edit: This answer may be wrong in the future. It should be possible to achieve these results using SVG Vector Effects, by combining veStrokePath with veIntersect (for 'inside') or with veExclude (for 'outside). However, Vector Effects are still a working draft module with no implementations that I can yet find.

Edit 2: The SVG 2 draft specification includes a stroke-alignment property (with center|inside|outside possible values). This property may make it into UAs eventually.

Edit 3: Amusingly and dissapointingly, the SVG working group has removed stroke-alignment from SVG 2. You can see some of the concerns described after the prose here.

It works perfectly. I have gcc compiler C++11 ready. Try this and you'll see:

#include <iostream>

using namespace std;

int main()
{
    int pause;

    struct Customer
    {
           int uid;
           string name;
    };

    Customer customerRecords[2];
    customerRecords[0] = {25, "Bob Jones"};
    customerRecords[1] = {26, "Jim Smith"};
    cout << customerRecords[0].uid << " " << customerRecords[0].name << endl;
    cout << customerRecords[1].uid << " " << customerRecords[1].name << endl;
    cin >> pause;
return 0;
}

Using a $scope method on the controller, you can calculate what classes to output in the view. This is especially handy if you have a complex logic for calculating class names and it will reduce the amount of logic in your view by moving it to the controller:

app.controller('myController', function($scope) {

    $scope.className = function() {

        var className = 'initClass';

        if (condition1())
            className += ' class1';

        if (condition2())
            className += ' class2';

        return className;
    };
});

and in the view, simply:

<div ng-class="className()"></div>

The correct way to use LOCK TABLES and UNLOCK TABLES with transactional tables, such as InnoDB tables, is to begin a transaction with SET autocommit = 0 (not START TRANSACTION) followed by LOCK TABLES, and to not call UNLOCK TABLES until you commit the transaction explicitly. For example, if you need to write to table t1 and read from table t2, you can do this:

SET autocommit=0;
LOCK TABLES t1 WRITE, t2 READ, ...;... do something with tables t1 and t2 here ...
COMMIT;
UNLOCK TABLES;

nginx is useful for forwarding HTTP on many platforms including Windows. It's easy to setup and extend with more advanced configuration. A basic configuration could look something like this:

events {}

http {
     server {

        listen 192.168.1.111:4422;

        location / {
            proxy_pass http://192.168.2.33:80/;
        }
     }
}

Alternatively you could read you csv with header=None and then add it with df.columns:

Cov = pd.read_csv("path/to/file.txt", sep='\t', header=None)
Cov.columns = ["Sequence", "Start", "End", "Coverage"]

onProgressChanged() should be called on every progress changed, not just on first and last touch (that why you have onStartTrackingTouch() and onStopTrackingTouch() methods).

Make sure that your SeekBar have more than 1 value, that is to say your MAX>=3.

In your onCreate:

 yourSeekBar=(SeekBar) findViewById(R.id.yourSeekBar);
 yourSeekBar.setOnSeekBarChangeListener(new yourListener());

Your listener:

private class yourListener implements SeekBar.OnSeekBarChangeListener {

        public void onProgressChanged(SeekBar seekBar, int progress,
                boolean fromUser) {
                            // Log the progress
            Log.d("DEBUG", "Progress is: "+progress);
                            //set textView's text
            yourTextView.setText(""+progress);
        }

        public void onStartTrackingTouch(SeekBar seekBar) {}

        public void onStopTrackingTouch(SeekBar seekBar) {}

    }

I noticed the issue the moment I updated Chrome on os x to the latest stable release (9.0.597.94) so this is a Chrome bug and hopefully will be fixed.

I'm tempted not to even attempt to work around this and just wait for the fix. It'll just mean more work taking it out.

I found another relatively easy solution for your question.

As you can see from the FragmentPagerAdapter source code, the fragments managed by FragmentPagerAdapter store in the FragmentManager under the tag generated using:

String tag="android:switcher:" + viewId + ":" + index;

The viewId is the container.getId(), the container is your ViewPager instance. The index is the position of the fragment. Hence you can save the object id to the outState:

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putInt("viewpagerid" , mViewPager.getId() );
}

@Override
    protected void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.activity_main);
    if (savedInstanceState != null)
        viewpagerid=savedInstanceState.getInt("viewpagerid", -1 );  

    MyFragmentPagerAdapter titleAdapter = new MyFragmentPagerAdapter (getSupportFragmentManager() , this);        
    mViewPager = (ViewPager) findViewById(R.id.pager);
    if (viewpagerid != -1 ){
        mViewPager.setId(viewpagerid);
    }else{
        viewpagerid=mViewPager.getId();
    }
    mViewPager.setAdapter(titleAdapter);

If you want to communicate with this fragment, you can get if from FragmentManager, such as:

getSupportFragmentManager().findFragmentByTag("android:switcher:" + viewpagerid + ":0")

Well, it depends on what language you are using, but in general they are 2 separate configurations, each with its own settings. By default, Debug includes debug information in the compiled files (allowing easy debugging) while Release usually has optimizations enabled.

As far as conditional compilation goes, they each define different symbols that can be checked in your program, but they are language-specific macros.

Try phoneNumber.setVisibility(View.GONE);

You should not use your domain models in your views. ViewModels are the correct way to do it.

You need to map your domain model's necessary fields to viewmodel and then use this viewmodel in your controllers. This way you will have the necessery abstraction in your application.

If you never heard of viewmodels, take a look at this.

It seems you can change the colour of the checkbox in grayscale by using CSS only.

The following converts the checkboxes from black to gray (which was about what I wanted):

input[type="checkbox"] {
    opacity: .5;
}

In my experience, the "I" convention applies to interfaces that are intended to provide a contract to a class, particularly when the interface itself is not an abstract notion of the class.

For example, in your case, I'd only expect to see IUser if the only user you ever intend to have is User. If you plan to have different types of users - NoviceUser, ExpertUser, etc. - I would expect to see a User interface (and, perhaps, an AbstractUser class that implements some common functionality, like get/setName()).

I would also expect interfaces that define capabilities - Comparable, Iterable, etc. - to be named like that, and not like IComparable or IIterable.

tl;dr:

concat and append currently sort the non-concatenation index (e.g. columns if you're adding rows) if the columns don't match. In pandas 0.23 this started generating a warning; pass the parameter sort=True to silence it. In the future the default will change to not sort, so it's best to specify either sort=True or False now, or better yet ensure that your non-concatenation indices match.

The warning is new in pandas 0.23.0:

In a future version of pandas pandas.concat() and DataFrame.append() will no longer sort the non-concatenation axis when it is not already aligned. The current behavior is the same as the previous (sorting), but now a warning is issued when sort is not specified and the non-concatenation axis is not aligned, link.

More information from linked very old github issue, comment by smcinerney :

When concat'ing DataFrames, the column names get alphanumerically sorted if there are any differences between them. If they're identical across DataFrames, they don't get sorted.

This sort is undocumented and unwanted. Certainly the default behavior should be no-sort.

After some time the parameter sort was implemented in pandas.concat and DataFrame.append:

sort : boolean, default None

Sort non-concatenation axis if it is not already aligned when join is 'outer'. The current default of sorting is deprecated and will change to not-sorting in a future version of pandas.

Explicitly pass sort=True to silence the warning and sort. Explicitly pass sort=False to silence the warning and not sort.

This has no effect when join='inner', which already preserves the order of the non-concatenation axis.

So if both DataFrames have the same columns in the same order, there is no warning and no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['a', 'b'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['b', 'a'])

print (pd.concat([df1, df2]))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

But if the DataFrames have different columns, or the same columns in a different order, pandas returns a warning if no parameter sort is explicitly set (sort=None is the default value):

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])

print (pd.concat([df1, df2]))

FutureWarning: Sorting because non-concatenation axis is not aligned.

   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=True))
   a  b
0  1  0
1  2  8
0  4  7
1  5  3

print (pd.concat([df1, df2], sort=False))
   b  a
0  0  1
1  8  2
0  7  4
1  3  5

If the DataFrames have different columns, but the first columns are aligned - they will be correctly assigned to each other (columns a and b from df1 with a and b from df2 in the example below) because they exist in both. For other columns that exist in one but not both DataFrames, missing values are created.

Lastly, if you pass sort=True, columns are sorted alphanumerically. If sort=False and the second DafaFrame has columns that are not in the first, they are appended to the end with no sorting:

df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8], 'e':[5, 0]}, 
                    columns=['b', 'a','e'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3], 'c':[2, 8], 'd':[7, 0]}, 
                    columns=['c','b','a','d'])

print (pd.concat([df1, df2]))

In your code:

placement_by_video_summary = placement_by_video_summary.drop(placement_by_video_summary_new.index)
                                                       .append(placement_by_video_summary_new, sort=True)
                                                       .sort_index()

I made an experiment using the magic method __call. Not sure if I should post it (because of all the "DO NOT USE MAGIC METHODS" warnings in the other answers and comments) but i'll leave it here.. just in case someone find it useful.

public function __call($_name, $_arguments){
    $action  = substr($_name, 0, 4);
    $varName = substr($_name, 4);

    if (isset($this->{$varName})){
        if ($action === "get_") return $this->{$varName};
        if ($action === "set_") $this->{$varName} = $_arguments[0];
    }
}

Just add that method above in your class, now you can type:

class MyClass{
    private foo = "bar";
    private bom = "bim";
    // ...
    // public function __call(){ ... }
    // ...
}
$C = new MyClass();

// as getter
$C->get_foo(); // return "bar"
$C->get_bom(); // return "bim"

// as setter
$C->set_foo("abc"); // set "abc" as new value of foo
$C->set_bom("zam"); // set "zam" as new value of bom

This way you can get/set everything in your class if it exist so, if you need it for only a few specific elements, you could use a "whitelist" as filter.

Example:

private $callWhiteList = array(
    "foo" => "foo",
    "fee" => "fee",
    // ...
);

public function __call($_name, $_arguments){
    $action  = substr($_name, 0, 4);
    $varName = $this->callWhiteList[substr($_name, 4)];

    if (!is_null($varName) && isset($this->{$varName})){
        if ($action === "get_") return $this->{$varName};
        if ($action === "set_") $this->{$varName} = $_arguments[0];
    }
}

Now you can only get/set "foo" and "fee".
You can also use that "whitelist" to assign custom names to access to your vars.
For example,

private $callWhiteList = array(
    "myfoo" => "foo",
    "zim" => "bom",
    // ...
);

With that list you can now type:

class MyClass{
    private foo = "bar";
    private bom = "bim";
    // ...
    // private $callWhiteList = array( ... )
    // public function __call(){ ... }
    // ...
}
$C = new MyClass();

// as getter
$C->get_myfoo(); // return "bar"
$C->get_zim(); // return "bim"

// as setter
$C->set_myfoo("abc"); // set "abc" as new value of foo
$C->set_zim("zam"); // set "zam" as new value of bom

.
.
.
That's all.

Doc: __call() is triggered when invoking inaccessible methods in an object context.

You can write a TCL script and establish SSH session to that Linux machine and issue commands automatically. Check http://wiki.tcl.tk/11542 for a short tutorial.

you can do this in the following ways:

Method 1:

1. Create a list and store all the hashset values into it
2. sort the list using Collections.sort()
3. Store the list back into LinkedHashSet as it preserves the insertion order

Method 2:

• Create a treeSet and store all the values into it.

Method 2 is more preferable because the other method consumes lot of time to transfer data back and forth between hashset and list.

When you use find(), it automatically assumes your primary key column is going to be id. In order for this to work correctly, you should set your primary key in your model.

So in Song.php, within the class, add the line...

protected $primaryKey = 'SongID';

If there is any possibility of changing your schema, I'd highly recommend naming all your primary key columns id, it's what Laravel assumes and will probably save you from more headaches down the road.

You can use a Singleton Pattern like this:

package com.ramps;

public class MyProperties {
private static MyProperties mInstance= null;

public int someValueIWantToKeep;

protected MyProperties(){}

public static synchronized MyProperties getInstance() {
        if(null == mInstance){
            mInstance = new MyProperties();
        }
        return mInstance;
    }
}

In your application you can access your singleton in this way:

MyProperties.getInstance().someValueIWantToKeep

You can use .deepEqual()

const { assert } = require('chai');

assert.deepEqual([0,0], [0,0]);

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

Here are two methods, one sweet and simple(and conceptual), the other more formal and can be extended in a variety of situations, after having read a dataset.

Method 1: Conceptual

X2=[]
X1=[1,2,3]
X2.append(X1)
X3=[4,5,6]
X2.append(X3)
X2 thus has [[1,2,3],[4,5,6]] ie a list of lists. 

Method 2 : Formal and extensible

Another elegant way to store a list as a list of lists of different numbers - which it reads from a file. (The file here has the dataset train) Train is a data-set with say 50 rows and 20 columns. ie. Train[0] gives me the 1st row of a csv file, train[1] gives me the 2nd row and so on. I am interested in separating the dataset with 50 rows as one list, except the column 0 , which is my explained variable here, so must be removed from the orignal train dataset, and then scaling up list after list- ie a list of a list. Here's the code that does that.

Note that I am reading from "1" in the inner loop since I am interested in explanatory variables only. And I re-initialize X1=[] in the other loop, else the X2.append([0:(len(train[0])-1)]) will rewrite X1 over and over again - besides it more memory efficient.

X2=[]
for j in range(0,len(train)):
    X1=[]
    for k in range(1,len(train[0])):
        txt2=train[j][k]
        X1.append(txt2)
    X2.append(X1[0:(len(train[0])-1)])

You'd obviously figure it out after a while but just posting this so that it might help someone. This could also happen when your file path contains any whitespace appended or prepended to it.

In your css add a class:

.fa-clickable {
    cursor:pointer;
    outline:none;
}

Then add the class to the clickable fontawesome icons (also an id so you can differentiate the clicks):

 <i class="fa fa-dribbble fa-4x fa-clickable" id="epd-dribble"></i>
 <i class="fa fa-behance-square fa-4x fa-clickable" id="epd-behance"></i>
 <i class="fa fa-linkedin-square fa-4x fa-clickable" id="epd-linkedin"></i>
 <i class="fa fa-twitter-square fa-4x fa-clickable" id="epd-twitter"></i>
 <i class="fa fa-facebook-square fa-4x fa-clickable" id="epd-facebook"></i>

Then add a handler in your jQuery

$(document).on("click", "i", function(){
    switch (this.id) {
        case "epd-dribble":
            // do stuff
            break;
        // add additional cases
    }
});

You can use the datapart to maintain time date type and you can compare it to another time.
Check below example:

I know no-one is asking for a jQuery solution here, but might be worth mentioning that with jQuery you can just ask for:$('#selectorid').val()

I had this same problem, do this

if [ 'xyz' = 'abc' ]; then
  echo "match"
fi

Notice the whitespace. It is important that you use a whitespace in this case after and before the = sign.

Check out "Other Comparison Operators".

If your grep supports -R, do:

grep -R 'string' dir/

If not, then use find:

find dir/ -type f -exec grep -H 'string' {} +

If you know for sure that the element is present, you could try this to simulate the click - if .Click() isn't working

driver.findElement(By.name("submit")).sendKeys(Keys.RETURN);

or

driver.findElement(By.name("submit")).sendKeys(Keys.ENTER);

You can make td's align without changing the css by adding a div with a class of "text-center" inside the cell:

    <td>
        <div class="text-center">
            My centered text
        </div>
    </td>

If you wanted to use the DB facade:

DB::table('table_name')->whereNotNull('sent_at')->get();

Another solution (without selecting HTML DOM elements )

If you added 'change' event listener on that input, then in javascript code you can call (for some specified conditions):

event.target.value = '';

For example in HTML:

<input type="file" onChange="onChangeFunction(event)">

And in javascript:

onChangeFunction(event) {
  let fileList = event.target.files;
  let file = fileList[0];
  let extension = file.name.match(/(?<=\.)\w+$/g)[0].toLowerCase(); // assuming that this file has any extension

  if (extension === 'jpg') {
    alert('Good file extension!');
  }
  else {
    event.target.value = '';
    alert('Wrong file extension! File input is cleared.');
  }

For Eclipse, setting -Dspring.profiles.active variable in the VM arguments would do the trick.

Go to

Right Click Project --> Run as --> Run Configurations --> Arguments

And add your -Dspring.profiles.active=dev in the VM arguments

It means another user is accessing the database. Simply restart PostgreSQL. This command will do the trick

root@kalilinux:~#sudo service postgresql restart

Then try dropping the database:

postgres=# drop database test_database;

This will do the trick.

file version < 5 : file -i -b /path/to/file
file version >=5 : file --mime-type -b /path/to/file

Make use of Relative layout it will adjust the view so that you can see that view while typing the text

You can use a ViewPropertyAnimator with a slight twist. To collapse, scale the view to a height of 1 pixel, then hide it. To expand, show it, then expand it to its height.

private void collapse(final View view) {
    view.setPivotY(0);
    view.animate().scaleY(1/view.getHeight()).setDuration(1000).withEndAction(new Runnable() {
        @Override public void run() {
            view.setVisibility(GONE);
        }
    });
}

private void expand(View view, int height) {
    float scaleFactor = height / view.getHeight();

    view.setVisibility(VISIBLE);
    view.setPivotY(0);
    view.animate().scaleY(scaleFactor).setDuration(1000);
}

The pivot tells the view where to scale from, default is in the middle. The duration is optional (default = 1000). You can also set the interpolator to use, like .setInterpolator(new AccelerateDecelerateInterpolator())

For Spring Tool Suite I do:

File -> Open projects from File System

Use below code for that

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="35dp"
    android:orientation="horizontal" >

    <TextView
        android:id="@+id/lblExpenseCancel"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_marginTop="9dp"
        android:text="@string/cancel"
        android:textColor="#404040"
        android:textSize="20sp" />

    <Button
        android:id="@+id/btnAddExpense"
        android:layout_width="wrap_content"
        android:layout_height="45dp"
        android:layout_alignParentRight="true"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="15dp"
        android:background="@drawable/stitch_button"
        android:text="@string/add" />

</RelativeLayout>

You can run this command for making a factory reset:

killall dropbear uhttpd; sleep 1; mtd -r erase rootfs_data

Alternatively you can just create a tunnel to the server:

ssh -i <your_key> <user@server-instance> -L 8888:127.0.0.1:8888

Then just open 127.0.0.1:8888 in your browser.

You also omit the -i <your_key> if you don't have an identity_file.

Utilizing/Copying Darin Dimitrov's great response, this is how to access a custom attribute on a property and not a class:

The decorated property [of class Foo]:

[MyCustomAttribute(SomeProperty = "This is a custom property")]
public string MyProperty { get; set; }

Fetching it:

PropertyInfo propertyInfo = typeof(Foo).GetProperty(propertyToCheck);
object[] attribute = propertyInfo.GetCustomAttributes(typeof(MyCustomAttribute), true);
if (attribute.Length > 0)
{
    MyCustomAttribute myAttribute = (MyCustomAttribute)attribute[0];
    string propertyValue = myAttribute.SomeProperty;
}

You can throw this in a loop and use reflection to access this custom attribute on each property of class Foo, as well:

foreach (PropertyInfo propertyInfo in Foo.GetType().GetProperties())
{
    string propertyName = propertyInfo.Name;

    object[] attribute = propertyInfo.GetCustomAttributes(typeof(MyCustomAttribute), true);
    // Just in case you have a property without this annotation
    if (attribute.Length > 0)
    {
        MyCustomAttribute myAttribute = (MyCustomAttribute)attribute[0];
        string propertyValue = myAttribute.SomeProperty;
        // TODO: whatever you need with this propertyValue
    }
}

Major thanks to you, Darin!!

I got solution after using below command:

git repack -a -f -d --window=250 --depth=250

DateTime itself contains no real timezone information. It may know if it's UTC or local, but not what local really means.

DateTimeOffset is somewhat better - that's basically a UTC time and an offset. However, that's still not really enough to determine the timezone, as many different timezones can have the same offset at any one point in time. This sounds like it may be good enough for you though, as all you've got to work with when parsing the date/time is the offset.

The support for time zones as of .NET 3.5 is a lot better than it was, but I'd really like to see a standard "ZonedDateTime" or something like that - a UTC time and an actual time zone. It's easy to build your own, but it would be nice to see it in the standard libraries.

EDIT: Nearly four years later, I'd now suggest using Noda Time which has a rather richer set of date/time types. I'm biased though, as the main author of Noda Time :)

tests are supposed to improve maintainability. If you change a method and a test breaks that can be a good thing. On the other hand, if you look at your method as a black box then it shouldn't matter what is inside the method. The fact is you need to mock things for some tests, and in those cases you really can't treat the method as a black box. The only thing you can do is to write an integration test -- you load up a fully instantiated instance of the service under test and have it do its thing like it would running in your app. Then you can treat it as a black box.

When I'm writing tests for a method, I have the feeling of rewriting a second time what I          
already wrote in the method itself.
My tests just seems so tightly bound to the method (testing all codepath, expecting some    
inner methods to be called a number of times, with certain arguments), that it seems that
if I ever refactor the method, the tests will fail even if the final behavior of the   
method did not change.

This is because you are writing your tests after you wrote your code. If you did it the other way around (wrote the tests first) it wouldnt feel this way.

For maintainability, I would attach the "blocking" handler on the element itself (in your case, the canvas).

theCanvas.onkeydown = function (e) {
    if (e.key === 'ArrowUp' || e.key === 'ArrowDown') {
        e.view.event.preventDefault();
    }
}

Why not simply do window.event.preventDefault()? MDN states:

window.event is a proprietary Microsoft Internet Explorer property which is only available while a DOM event handler is being called. Its value is the Event object currently being handled.

Since it wasn't stated clearly, I just add this:

I was looking for a way to create a table which holds the number of occurrences of all the data types.

Say we have a data.frame with two numeric and one logical column

dta <- data.frame(a = c(1,2,3), 
                  b = c(4,5,6), 
                  c = c(TRUE, FALSE, TRUE))

You can summarize the number of columns of each data type with that

table(unlist(lapply(dta, class)))
# logical numeric 
#       1       2 

This comes extremely handy, if you have a lot of columns and want to get a quick overview.

To give credit: This solution was inspired by the answer of @Cybernetic.

Here's a different approach. The heart of it was created by turning on the Macro Recorder and filtering the columns per your specifications. Then there's a bit of code to copy the results. It will run faster than looping through each row and column:

Sub FilterAndCopy()
Dim LastRow As Long

Sheets("Sheet2").UsedRange.Offset(0).ClearContents
With Worksheets("Sheet1")
    .Range("$A:$E").AutoFilter
    .Range("$A:$E").AutoFilter field:=1, Criteria1:="#N/A"
    .Range("$A:$E").AutoFilter field:=2, Criteria1:="=String1", Operator:=xlOr, Criteria2:="=string2"
    .Range("$A:$E").AutoFilter field:=3, Criteria1:=">0"
    .Range("$A:$E").AutoFilter field:=5, Criteria1:="Number"
    LastRow = .Range("A" & .Rows.Count).End(xlUp).Row
    .Range("A1:A" & LastRow).SpecialCells(xlCellTypeVisible).EntireRow.Copy _
            Destination:=Sheets("Sheet2").Range("A1")
End With
End Sub

As a side note, your code has more loops and counter variables than necessary. You wouldn't need to loop through the columns, just through the rows. You'd then check the various cells of interest in that row, much like you did.

Remove the \s from your new regex and it should work - whitespace is already included in "anything but alphanumerics".

Note that you may want to add a + after the ] so you don't get sequences of more than one underscore. You can also chain onto .replace(/^_+|_+$/g,'') to trim off underscores at the start or end of the string.

The answer of delfuego is the simplest way to solve the certificate problem. But, in my case, one of our third party url (using https), updated their certificate every 2 months automatically. It means that I have to import the cert to our Java trust store manually every 2 months as well. Sometimes it caused production problems.

So, I made a method to solve it with SecureRestClientTrustManager to be able to consume https url without importing the cert file. Here is the method:

     public static String doPostSecureWithHeader(String url, String body, Map headers)
            throws Exception {
        log.info("start doPostSecureWithHeader " + url + " with param " + body);
        long startTime;
        long endTime;
        startTime = System.currentTimeMillis();
        Client client;
        client = Client.create();
        WebResource webResource;
        webResource = null;
        String output = null;
        try{
            SSLContext sslContext = null;
            SecureRestClientTrustManager secureRestClientTrustManager = new SecureRestClientTrustManager();
            sslContext = SSLContext.getInstance("SSL");
            sslContext
            .init(null,
                    new javax.net.ssl.TrustManager[] { secureRestClientTrustManager },
                    null);
            DefaultClientConfig defaultClientConfig = new DefaultClientConfig();
            defaultClientConfig
            .getProperties()
            .put(com.sun.jersey.client.urlconnection.HTTPSProperties.PROPERTY_HTTPS_PROPERTIES,
                    new com.sun.jersey.client.urlconnection.HTTPSProperties(
                            getHostnameVerifier(), sslContext));

            client = Client.create(defaultClientConfig);
            webResource = client.resource(url);

            if(headers!=null && headers.size()>0){
                for (Map.Entry entry : headers.entrySet()){
                    webResource.setProperty(entry.getKey(), entry.getValue());
                }
            }
            WebResource.Builder builder = 
                    webResource.accept("application/json");
            if(headers!=null && headers.size()>0){
                for (Map.Entry entry : headers.entrySet()){
                    builder.header(entry.getKey(), entry.getValue());
                }
            }

            ClientResponse response = builder
                    .post(ClientResponse.class, body);
            output = response.getEntity(String.class);
        }
        catch(Exception e){
            log.error(e.getMessage(),e);
            if(e.toString().contains("One or more of query value parameters are null")){
                output="-1";
            }
            if(e.toString().contains("401 Unauthorized")){
                throw e;
            }
        }
        finally {
            if (client!= null) {
                client.destroy();
            }
        }
        endTime = System.currentTimeMillis();
        log.info("time hit "+ url +" selama "+ (endTime - startTime) + " milliseconds dengan output = "+output);
        return output;
    }

A reproducible example:

the_plot <- function()
{
  x <- seq(0, 1, length.out = 100)
  y <- pbeta(x, 1, 10)
  plot(
    x,
    y,
    xlab = "False Positive Rate",
    ylab = "Average true positive rate",
    type = "l"
  )
}

James's suggestion of using pointsize, in combination with the various cex parameters, can produce reasonable results.

png(
  "test.png",
  width     = 3.25,
  height    = 3.25,
  units     = "in",
  res       = 1200,
  pointsize = 4
)
par(
  mar      = c(5, 5, 2, 2),
  xaxs     = "i",
  yaxs     = "i",
  cex.axis = 2,
  cex.lab  = 2
)
the_plot()
dev.off()

Of course the better solution is to abandon this fiddling with base graphics and use a system that will handle the resolution scaling for you. For example,

library(ggplot2)

ggplot_alternative <- function()
{
  the_data <- data.frame(
    x <- seq(0, 1, length.out = 100),
    y = pbeta(x, 1, 10)
  )

ggplot(the_data, aes(x, y)) +
    geom_line() +
    xlab("False Positive Rate") +
    ylab("Average true positive rate") +
    coord_cartesian(0:1, 0:1)
}

ggsave(
  "ggtest.png",
  ggplot_alternative(),
  width = 3.25,
  height = 3.25,
  dpi = 1200
)

json = File.ReadAllText(System.AppDomain.CurrentDomain.BaseDirectory + "App_Data\\" +download_file[0]);
DataTable dt = (DataTable)JsonConvert.DeserializeObject(json, (typeof(DataTable)));

try this code [updated]:

Scanner scan = null;
       int range, smallest = 0, input;

     for(;;){
         boolean error=false;
        scan = new Scanner(System.in);
        System.out.print("Enter an integer between 1-100:  ");


            if(!scan.hasNextInt()) {
                System.out.println("Invalid input!");                      
                continue;
            }
         range = scan.nextInt();
            if(range < 1) {
                System.out.println("Invalid input!");
                error=true;
            }
        if(error)
        {
        //do nothing
        }
        else
        {
       break;
        }

        }
             for(int ii = 1; ii <= range; ii++) {
            scan = new Scanner(System.in);
            System.out.print("Enter value " + ii + ": ");

            if(!scan.hasNextInt()) {
                System.out.println("Invalid input!"); 
               ii--;
                continue;
            } 
        }

Ok, here is the JS code:

var data = JSON.parse('{"c":{"a":{"name":"cable - black","value":2}}}')

for (var event in data) {
    var dataCopy = data[event];
    for (data in dataCopy) {
        var mainData = dataCopy[data];
        for (key in mainData) {
            if (key.match(/name|value/)) {
                alert('key : ' + key + ':: value : ' + mainData[key])
            }
        }
    }
}?

FIDDLE HERE

max233 was certainly on the right track, at least for the autoincrement case. However, do not do the ALTER TABLE. Simply set the auto-increment field in the temporary table to NULL. This will present an error, but the following INSERT of all fields in the temporary table will happen and the NULL auto field will obtain a unique value.

There is always this of course:

(async () => {
    await ...

    // all of the script.... 

})();
// nothing else

This makes a quick function with async where you can use await. It saves you the need to make an async function which is great! //credits Silve2611

Very simple was to renew your certificate. Go to your developer member centre and go to your Provisioning profile and see what are the certificate Active and InActive and select Inactive certificate and hit Edit button then hit generate button. Now your certificate successful renewal for another 1 year. Thanks

For Gradle projects:

1. Exit IntelliJ IDEA
2. Delete the <problematic-project-root>/.idea directory
3. Delete the <problematic-project-root>/.gradle directory
4. Delete all .iml files in <problematic-project-root>
   • windows command prompt: DEL /S /Q *.iml
   • linux: find . | grep -e .iml$ | xargs rm
5. Re-import the project into IntelliJ IDEA with Gradle

According to your example here it seems that they both reside in the same namespace, i conclude that they are both part of the same project ( if you haven't created another project with the same namespace) and all class by default are defined as internal to the project they are defined in, if haven't declared otherwise, therefore i guess the problem is that your file is not included in your project. You can include it by right clicking the file in the solution explorer window => Include in project, if you cannot see the file inside the project files in the solution explorer then click the show the upper menu button of the solution explorer called show all files ( just hove your mouse cursor over the button there and you'll see the names of the buttons)

Just for basic knowledge: If the file resides in a different project\ assembly then it has to be defined, otherwise it has to be define at least as internal or public. in case your class is inheriting from that class that it can be protected as well.

I managed to fix this by adding:

android:layout_marginTop="?android:attr/actionBarSize"

to the FrameLayout like so:

 <FrameLayout
        android:id="@+id/content"
        android:layout_marginTop="?android:attr/actionBarSize"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
       />

import java.util.*;


public class matrixcecil {
    public static void main(String args[]){
        List<Integer> k1=new ArrayList<Integer>(10);
        k1.add(23);
        k1.add(10);
        k1.add(20);
        k1.add(24);
        int i=0;
        while(k1.size()<10){
            if(i==(k1.get(k1.size()-1))){

            }
             i=k1.get(k1.size()-1);
             k1.add(30);
             i++;
             break;
        }
        System.out.println(k1);
    }

}

I think this example will help you for better solution.

No jQuery needed.

Some people say using onclick is bad practice...

This example uses pure browser javascript. By default, it appears that the click handler will evaluate before the navigation, so you can cancel the navigation and do your own if you wish.

<a id="myButton" href="http://google.com">Click me!</a>
<script>
    window.addEventListener("load", () => {
        document.querySelector("#myButton").addEventListener("click", e => {
            alert("Clicked!");
            // Can also cancel the event and manually navigate
            // e.preventDefault();
            // window.location = e.target.href;
        });
    });
</script>

-> mysql -h host -u user -p database_name table_name < test_table.sql

make sure you use the POST to insert the data. Actually you were using GET.

JDK (Java Development Kit) :

I know its an old question. This problem can be easily reproduced if you try to reinitialize the Datatable again.

For example in your function somewhere you are calling $('#example').DataTable( { searching: false} ); again.

There is easy resolving this issue. Please follow the steps

1. Initialize the Datatable to a variable rather than directly initializing DataTable method.
   1. For Example Instead of calling $('#example').DataTable( { searching: false} ); try to declare it globally (or in scope of javascription that you are using) like this var table = $('#example').DataTable( { searching: false } );.
2. Now Whenever you are calling this method $('#example').DataTable( { searching: false} ); again then before calling it perform the following actions
   3. if (table != undefined && table != null) { table.destroy(); table = null; }
3. Once you have followed the steps above then go ahead with re-initializing the table with same variable without using var keyword (as you have already defined it) i.e table = $('#example').DataTable( { searching: false } );

JSFiddle Code Also attached for any reference of same code http://jsfiddle.net/vibs2006/qxy4nwfg/

you can do in 2 way :

1. create style as you already gave in div but change border-left to border-right
2. take a image and make its width 1-2 px

First get Extension just press (Ctrl + Shift + X) and install getter setter ....

After this, just select your variable and right click. Go to Command palette...

And type getter ... It will suggest generate get and set methods. Click on this...

You can determine if as certain word is found in a cell by using

If InStr(cell.Value, "Word1") > 0 Then

If Word1 is found in the string the InStr() function will return the location of the first character of Word1 in the string.

If you want to get the navigationBar height only, it's simple:

extension UIViewController{
   var navigationBarHeight: CGFloat {
       return self.navigationController?.navigationBar.frame.height ?? 0.0
   }
}

However, if you need the height of top notch of iPhone you don't need to get the navigationBar height and add to it the statusBar height, you can simply call safeAreaInsets that's why exist.

self.view.safeAreaInsets.top

?? The accepted solution is outdated.

Here are two scenarios where the keyup event will not get fired:

1. The user drags text into the textarea.
2. The user copy-paste text in the textarea with a right click (contextual menu).

Use the HTML5 input event instead for a more robust solution:

<textarea maxlength='140'></textarea>

JavaScript (demo):

const textarea = document.querySelector("textarea");

textarea.addEventListener("input", event => {
    const target = event.currentTarget;
    const maxLength = target.getAttribute("maxlength");
    const currentLength = target.value.length;

    if (currentLength >= maxLength) {
        return console.log("You have reached the maximum number of characters.");
    }

    console.log(`${maxLength - currentLength} chars left`);
});

And if you absolutely want to use jQuery:

$('textarea').on("input", function(){
    var maxlength = $(this).attr("maxlength");
    var currentLength = $(this).val().length;

    if( currentLength >= maxlength ){
        console.log("You have reached the maximum number of characters.");
    }else{
        console.log(maxlength - currentLength + " chars left");
    }
});

Ok, at that time got it done with the help of a friend and the code looks like this.

Sub Saving()

Dim part1 As String

Dim part2 As String


part1 = Range("C5").Value

part2 = Range("C8").Value


ActiveWorkbook.SaveAs Filename:= _

"C:\-docs\cmat\Desktop\pieteikumi\" & part1 & " " & part2 & ".xlsm", FileFormat:= _
xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False

End Sub

How do I edit this part (FileFormat:= _ xlOpenXMLWorkbookMacroEnabled) for it to save as Excel 97-2013 Workbook, have tried several variations with no success. Thankyou

Seems, that I found the solution, but my idea is flawed. By doing this FileFormat:= _ xlOpenXMLWorkbook, it drops out a popup saying, the you cannot save this workbook as a file without Macro enabled. So, is this impossible?

Use the command

git clone --help

to see whether your git supports the command

git clone --branch tag_name

If not, just do the following:

git clone repo_url 
cd repo
git checkout tag_name

Quick Answer (TL;DR)

    %hash1 = (%hash1, %hash2)

    ## or else ...

    @hash1{keys %hash2} = values %hash2;

    ## or with references ...

    $hash_ref1 = { %$hash_ref1, %$hash_ref2 };

Overview

• Context: Perl 5.x
• Problem: The user wishes to merge two hashes¹ into a single variable

Solution

• use the syntax above for simple variables
• use Hash::Merge for complex nested variables

Pitfalls

• What do to when both hashes contain one or more duplicate keys
  • (see e.g., Perl - Merge hash containing duplicate keys)
  • (see e.g, Perl hashes: how to deal with duplicate keys and get possible pair)
• Should a key-value pair with an empty value ever overwrite a key-value pair with a non-empty value?
  • What constitutes an empty vs non-empty value in the first place? (eg. undef, zero, empty string, false, falsy ...)

¹ * (aka associative-array, aka dictionary)

You can not mock variable but you can create getter function for it and mock that method in your spec file.

Use JsonNode of fasterxml for the Generic Json Parsing. It internally creates a Map of key value for all the inputs.

Example:

private void test(@RequestBody JsonNode node)

input String :

{"a":"b","c":"d"}

A real time and simple solution:

$('form').on('keyup change paste', 'input, select, textarea', function(){
    console.log('Form changed!');
});

I know it's old post, but I thought this is a good addition: You can use List<T>.ConvertAll<TOutput>

List<int> integers = strings.ConvertAll(s => Int32.Parse(s));

Using int.TryParse will yield these results:

        var shouldBeInt = 3;

        var shouldntBeInt = 3.1415;

        var iDontWantThisToBeInt = 3.000f;

        Console.WriteLine(int.TryParse(shouldBeInt.ToString(), out int parser)); // true

        Console.WriteLine(int.TryParse(shouldntBeInt.ToString(), out parser)); // false

        Console.WriteLine(int.TryParse(iDontWantThisToBeInt.ToString(), out parser)); // true, even if I don't want this to be int

        Console.WriteLine(int.TryParse("3.1415", out  parser)); // false

        Console.WriteLine(int.TryParse("3.0000", out parser)); // false

        Console.WriteLine(int.TryParse("3", out parser)); // true

        Console.ReadKey();

Great anwser from Sameer and Abel Terefe. However, when you remove a view, in my option, you want to remove a view with certain id. Here is how do you do that.

1, give the view an id when you create it:

_textView.setId(index);

2, remove the view with the id:

removeView(findViewById(index));

Awesome, thank you!! Just had to make a few adjustments to get it working with ui-router:

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

    app.directive('head', ['$rootScope', '$compile', '$state', function ($rootScope, $compile, $state) {

    return {
        restrict: 'E',
        link: function ($scope, elem, attrs, ctrls) {

            var html = '<link rel="stylesheet" ng-repeat="(routeCtrl, cssUrl) in routeStyles" ng-href="{{cssUrl}}" />';
            var el = $compile(html)($scope)
            elem.append(el);
            $scope.routeStyles = {};

            function applyStyles(state, action) {
                var sheets = state ? state.css : null;
                if (state.parent) {
                    var parentState = $state.get(state.parent)
                    applyStyles(parentState, action);
                }
                if (sheets) {
                    if (!Array.isArray(sheets)) {
                        sheets = [sheets];
                    }
                    angular.forEach(sheets, function (sheet) {
                        action(sheet);
                    });
                }
            }

            $rootScope.$on('$stateChangeStart', function (event, toState, toParams, fromState, fromParams) {

                applyStyles(fromState, function(sheet) {
                    delete $scope.routeStyles[sheet];
                    console.log('>> remove >> ', sheet);
                });

                applyStyles(toState, function(sheet) {
                    $scope.routeStyles[sheet] = sheet;
                    console.log('>> add >> ', sheet);
                });
            });
        }
    }
}]);

It is not necessary to stop timer, see nice solution from this post:

"You could let the timer continue firing the callback method but wrap your non-reentrant code in a Monitor.TryEnter/Exit. No need to stop/restart the timer in that case; overlapping calls will not acquire the lock and return immediately."

private void CreatorLoop(object state) 
 {
   if (Monitor.TryEnter(lockObject))
   {
     try
     {
       // Work here
     }
     finally
     {
       Monitor.Exit(lockObject);
     }
   }
 }

It wasn't working for me either. vbcrlf and Environment.Newline() both had no effect. My problem was that the Placeholder Properties had a Markup type of HTML. When I changed it to None, it worked like a champ!

I was able to solve a problem similar to this in Visual Studio 2010 by using NuGet.

Go to Tools > Library Package Manager > Manage NuGet Packages For Solution...

In the dialog, search for "EntityFramework.SqlServerCompact". You'll find a package with the description "Allows SQL Server Compact 4.0 to be used with Entity Framework." Install this package.

An element similar to the following will be inserted in your web.config:

<entityFramework>
  <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlCeConnectionFactory, EntityFramework">
    <parameters>
      <parameter value="System.Data.SqlServerCe.4.0" />
    </parameters>
  </defaultConnectionFactory>
</entityFramework>

Wrapper classes came in to existence to fulfill a basic need of programmers - i.e. to use primitive values wherever only Objects are allowed. As their name suggests wrapper classes wrap around a primitive value and hold the value in an Object. So, all those places where primitives were not allowed - such as generics, hashmap-keys, Arraylists etc - programmers now have an option of providing these primitive values as their corresponding wrapper types.

In addition these wrapper types have a number of utility methods for converting from primitive type to corresponding wrapper types and back, and also from Strings to wrapper types and back.

I have written a detailed article on wrapper classes in a my blog which explains the concept of wrapper types in depth - http://www.javabrahman.com/corejava/java-wrapper-classes-tutorial-with-examples/ (Disclosure - This blog is owned by me)

There may be a simpler option, but you can use VLOOKUP to check if a value appears in a list (and VLOOKUP is a powerful formula to get to grips with anyway).

So for A1, you can set a conditional format using the following formula:

=NOT(ISNA(VLOOKUP(A1,$B:$B,1,FALSE)))

Copy and Paste Special > Formats to copy that conditional format to the other cells in column A.

What the above formula is doing:

• VLOOKUP is looking up the value of Cell A1 (first parameter) against the whole of column B ($B:$B), in the first column (that's the 3rd parameter, redundant here, but typically VLOOKUP looks up a table rather than a column). The last parameter, FALSE, specifies that the match must be exact rather than just the closest match.
• VLOOKUP will return #ISNA if no match is found, so the NOT(ISNA(...)) returns true for all cells which have a match in column B.

Another way.

try (BufferedReader reader = Files.newBufferedReader(
        Paths.get("file.txt"), StandardCharsets.UTF_8)) {
    List<String> line = reader.lines()
                              .skip(31)
                              .limit(1)
                              .collect(Collectors.toList());

    line.stream().forEach(System.out::println);
}

You should try this for the putting 2 array in singlr foreach loop Suppose i have 2 Array 1.$item_nm 2.$item_qty

 `<?php $i=1; ?>
<table><tr><td>Sr.No</td> <td>item_nm</td>  <td>item_qty</td>    </tr>

  @foreach (array_combine($item_nm, $item_qty) as $item_nm => $item_qty)
<tr> 
        <td> $i++  </td>
        <td>  $item_nm  </td>
        <td> $item_qty  </td>
   </tr></table>

@endforeach `

As we know filter and order by are removed from ANGULAR 2 and we need to write our own, here is a good example on plunker and detailed article

It used both filter as well as orderby, here is the code for order pipe

import { Pipe, PipeTransform } from '@angular/core';    
@Pipe({  name: 'orderBy' })
export class OrderrByPipe implements PipeTransform {

  transform(records: Array<any>, args?: any): any {       
    return records.sort(function(a, b){
          if(a[args.property] < b[args.property]){
            return -1 * args.direction;
          }
          else if( a[args.property] > b[args.property]){
            return 1 * args.direction;
          }
          else{
            return 0;
          }
        });
    };
 }

You can also get an EntityManager using PersistenceContext or Autowired annotation, but be aware that it will not be thread-safe.

@PersistenceContext
private EntityManager entityManager;

perhaps, you can first determine if the DOM does really exists,

function walkmydog() {
    //when the user starts entering
    var dom = document.getElementById('WallSearch');
    if(dom == null){
        alert('sorry, WallSearch DOM cannot be found');
        return false;    
    }

    if(dom.value.length == 0){
        alert("nothing");
    }
}

if (document.addEventListener){
    document.addEventListener("DOMContentLoaded", walkmydog, false);
}

if (/(^|;)\s*visited=/.test(document.cookie)) {
    alert("Hello again!");
} else {
    document.cookie = "visited=true; max-age=" + 60 * 60 * 24 * 10; // 60 seconds to a minute, 60 minutes to an hour, 24 hours to a day, and 10 days.
    alert("This is your first time!");
}

is one way to do it. Note that document.cookie is a magic property, so you don't have to worry about overwriting anything, either.

There are also more convenient libraries to work with cookies, and if you don’t need the information you’re storing sent to the server on every request, HTML5’s localStorage and friends are convenient and useful.

Assuming you are decoding or encoding xml and using JAXB, then it's possible to replace the dateTime binding entirely and use something else than `XMLGregorianCalendar' for every date in the schema.

In that way you can have JAXB do the repetitive stuff while you can spend the time on writing awesome code that delivers value.

Example for a jodatime DateTime: (Doing this with java.util.Date would also work - but with certain limitations. I prefer jodatime and it's copied from my code so I know it works...)

<jxb:globalBindings>
    <jxb:javaType name="org.joda.time.LocalDateTime" xmlType="xs:dateTime"
        parseMethod="test.util.JaxbConverter.parseDateTime"
        printMethod="se.seb.bis.test.util.JaxbConverter.printDateTime" />
    <jxb:javaType name="org.joda.time.LocalDate" xmlType="xs:date"
        parseMethod="test.util.JaxbConverter.parseDate"
        printMethod="test.util.JaxbConverter.printDate" />
    <jxb:javaType name="org.joda.time.LocalTime" xmlType="xs:time"
        parseMethod="test.util.JaxbConverter.parseTime"
        printMethod="test.util.JaxbConverter.printTime" />
    <jxb:serializable uid="2" />
</jxb:globalBindings>

And the converter:

public class JaxbConverter {
static final DateTimeFormatter dtf = ISODateTimeFormat.dateTimeNoMillis();
static final DateTimeFormatter df = ISODateTimeFormat.date();
static final DateTimeFormatter tf = ISODateTimeFormat.time();

public static LocalDateTime parseDateTime(String s) {
    try {
        if (StringUtils.trimToEmpty(s).isEmpty())
            return null;
        LocalDateTime r = dtf.parseLocalDateTime(s);
        return r;
    } catch (Exception e) {
        throw new IllegalArgumentException(e);
    }
}

public static String printDateTime(LocalDateTime d) {
    try {
        if (d == null)
            return null;
        return dtf.print(d);
    } catch (Exception e) {
        throw new IllegalArgumentException(e);
    }
}

public static LocalDate parseDate(String s) {
    try {
        if (StringUtils.trimToEmpty(s).isEmpty())
            return null;
        return df.parseLocalDate(s);
    } catch (Exception e) {
        throw new IllegalArgumentException(e);
    }
}

public static String printDate(LocalDate d) {
    try {
        if (d == null)
            return null;
        return df.print(d);
    } catch (Exception e) {
        throw new IllegalArgumentException(e);
    }
}

public static String printTime(LocalTime d) {
    try {
        if (d == null)
            return null;
        return tf.print(d);
    } catch (Exception e) {
        throw new IllegalArgumentException(e);
    }
}

public static LocalTime parseTime(String s) {
    try {
        if (StringUtils.trimToEmpty(s).isEmpty())
            return null;
        return df.parseLocalTime(s);
    } catch (Exception e) {
        throw new IllegalArgumentException(e);
    }
}

See here: how replace XmlGregorianCalendar by Date?

If you are happy to just map to an instant based on the timezone+timestamp, and the original timezone is not really relevant, then java.util.Date is probably fine too.

You can also try this:

  public string GetFormattedPhoneNumber(string phone)
        {
            if (phone != null && phone.Trim().Length == 10)
                return string.Format("({0}) {1}-{2}", phone.Substring(0, 3), phone.Substring(3, 3), phone.Substring(6, 4));
                return phone;
        }

Output:

SELECT
        *
FROM
        [SERVER2NAME].[THEDB].[THEOWNER].[THETABLE]

You can also look at using Linked Servers. Linked servers can be other types of data sources too such as DB2 platforms. This is one method for trying to access DB2 from a SQL Server TSQL or Sproc call...

As for your first question: that code is perfectly fine and should work if item equals one of the elements inside myList. Maybe you try to find a string that does not exactly match one of the items or maybe you are using a float value which suffers from inaccuracy.

As for your second question: There's actually several possible ways if "finding" things in lists.

Checking if something is inside

This is the use case you describe: Checking whether something is inside a list or not. As you know, you can use the in operator for that:

3 in [1, 2, 3] # => True

Filtering a collection

That is, finding all elements in a sequence that meet a certain condition. You can use list comprehension or generator expressions for that:

matches = [x for x in lst if fulfills_some_condition(x)]
matches = (x for x in lst if x > 6)

The latter will return a generator which you can imagine as a sort of lazy list that will only be built as soon as you iterate through it. By the way, the first one is exactly equivalent to

matches = filter(fulfills_some_condition, lst)

in Python 2. Here you can see higher-order functions at work. In Python 3, filter doesn't return a list, but a generator-like object.

Finding the first occurrence

If you only want the first thing that matches a condition (but you don't know what it is yet), it's fine to use a for loop (possibly using the else clause as well, which is not really well-known). You can also use

next(x for x in lst if ...)

which will return the first match or raise a StopIteration if none is found. Alternatively, you can use

next((x for x in lst if ...), [default value])

Finding the location of an item

For lists, there's also the index method that can sometimes be useful if you want to know where a certain element is in the list:

[1,2,3].index(2) # => 1
[1,2,3].index(4) # => ValueError

However, note that if you have duplicates, .index always returns the lowest index:......

[1,2,3,2].index(2) # => 1

If there are duplicates and you want all the indexes then you can use enumerate() instead:

[i for i,x in enumerate([1,2,3,2]) if x==2] # => [1, 3]

I too want to make some shine on abstract surface All answer has covered almost all the things. Still my 2 cents

abstract classes are normal classes with A few exceptions

1. You any client/Consumer of that class can't create object of that class, It never means that It's constructor will never call. Its derived class can choose which constructor to call.(as depicted in some answer)
2. It may has abstract function.

You may consider using CRON for that kind of operation. Sending mass mail at once is certainly not good, it may be detected as spam, ddos, crash your server etc.

So CRON could be a great solution, send 100 mails at once, then wait a few minutes, next 100, etc.

ImageView Button = (ImageView)findViewById(R.id.button);

Button.setOnClickListener(new OnClickListener() {

    public void onClick(View v) {
        Uri uri = Uri.parse("http://google.com/");

        Intent intent = new Intent(Intent.ACTION_VIEW, uri);
        startActivity(intent);
    }
});

The cookie API is kind of lame. Let me clarify...

You don't update cookies; you overwrite them:

    document.cookie = "username=Arnold"; // Create 'username' cookie
    document.cookie = "username=Chuck"; // Update, i.e. overwrite, the 'username' cookie to "Chuck"

You also don't delete cookies; you expire them by setting the expires key to a time in the past (-1 works too).

        filtered = inputString.componentsJoinedByString("")
        return  self == filtered

    }
}

Simple (Demo):

function sortedIndex(array, value) {
    var low = 0,
        high = array.length;

    while (low < high) {
        var mid = (low + high) >>> 1;
        if (array[mid] < value) low = mid + 1;
        else high = mid;
    }
    return low;
}

Tl;dr: Use a regex approach. It is 39x faster than the rescue approach in the accepted answer and also handles cases like "1,000"

def regex_is_number? string
  no_commas =  string.gsub(',', '')
  matches = no_commas.match(/-?\d+(?:\.\d+)?/)
  if !matches.nil? && matches.size == 1 && matches[0] == no_commas
    true
  else
    false
  end
end

--

The accepted answer by @Jakob S works for the most part, but catching exceptions can be really slow. In addition, the rescue approach fails on a string like "1,000".

Let's define the methods:

def rescue_is_number? string
  true if Float(string) rescue false
end

def regex_is_number? string
  no_commas =  string.gsub(',', '')
  matches = no_commas.match(/-?\d+(?:\.\d+)?/)
  if !matches.nil? && matches.size == 1 && matches[0] == no_commas
    true
  else
    false
  end
end

And now some test cases:

test_cases = {
  true => ["5.5", "23", "-123", "1,234,123"],
  false => ["hello", "99designs", "(123)456-7890"]
}

And a little code to run the test cases:

test_cases.each do |expected_answer, cases|
  cases.each do |test_case|
    if rescue_is_number?(test_case) != expected_answer
      puts "**rescue_is_number? got #{test_case} wrong**"
    else
      puts "rescue_is_number? got #{test_case} right"
    end

    if regex_is_number?(test_case) != expected_answer
      puts "**regex_is_number? got #{test_case} wrong**"
    else
      puts "regex_is_number? got #{test_case} right"
    end  
  end
end

Here is the output of the test cases:

rescue_is_number? got 5.5 right
regex_is_number? got 5.5 right
rescue_is_number? got 23 right
regex_is_number? got 23 right
rescue_is_number? got -123 right
regex_is_number? got -123 right
**rescue_is_number? got 1,234,123 wrong**
regex_is_number? got 1,234,123 right
rescue_is_number? got hello right
regex_is_number? got hello right
rescue_is_number? got 99designs right
regex_is_number? got 99designs right
rescue_is_number? got (123)456-7890 right
regex_is_number? got (123)456-7890 right

Time to do some performance benchmarks:

Benchmark.ips do |x|

  x.report("rescue") { test_cases.values.flatten.each { |c| rescue_is_number? c } }
  x.report("regex") { test_cases.values.flatten.each { |c| regex_is_number? c } }

  x.compare!
end

And the results:

Calculating -------------------------------------
              rescue   128.000  i/100ms
               regex     4.649k i/100ms

I don't know if this matters to you, but keep in mind that GUIDs are globally unique, but substrings of GUIDs aren't.

You can do this from the twig template:

{{ form_widget(form.birthdate, { 'attr': {'class': 'calendar'} }) }}

From http://symfony.com/doc/current/book/forms.html#rendering-each-field-by-hand

Try the following:

foo(*values)

This can be found in the Python docs as Unpacking Argument Lists.

my two cents for xcode 9.1 / swift 4.

class ViewController: UIViewController, UIPopoverPresentationControllerDelegate {

    override func viewDidLoad(){
        super.viewDidLoad()

        let when = DispatchTime.now() + 0.5

        DispatchQueue.main.asyncAfter(deadline: when, execute: { () -> Void in
            // to test after 05.secs... :)
            self.showPopover(base: self.view)

        })

}


func showPopover(base: UIView) {
    if let viewController = self.storyboard?.instantiateViewController(withIdentifier: "popover") as? PopOverViewController {

        let navController = UINavigationController(rootViewController: viewController)
        navController.modalPresentationStyle = .popover

        if let pctrl = navController.popoverPresentationController {
            pctrl.delegate = self

            pctrl.sourceView = base
            pctrl.sourceRect = base.bounds

            self.present(navController, animated: true, completion: nil)
        }
    }
}


@IBAction func onShow(sender: UIButton){
    self.showPopover(base: sender)
}

func adaptivePresentationStyle(for controller: UIPresentationController, traitCollection: UITraitCollection) -> UIModalPresentationStyle{
    return .none
}

and experiment in:

func adaptivePresentationStyle...

    return .popover

or: return .pageSheet.... and so on..

You could do Char(13) and Char(10). Cr and Lf.

Char() works in SQL Server, I don't know about other databases.

Think bitwise operators.

I missunderstood the question the first time. You should produce an int with the leftmost bit set (the others zero). Assuming cmp is set to that value:

position = sizeof(int)*8
while(!(n & cmp)){ 
   n <<=1;
   position--;
}

p.s. in particular, I've found Row-Oriented examples helpful; since often that how records are stored externally.

https://pbpython.com/pandas-list-dict.html

Just want to share another option:

# mark two objects to be deleted
session.delete(obj1)
session.delete(obj2)

# commit (or flush)
session.commit()

http://docs.sqlalchemy.org/en/latest/orm/session_basics.html#deleting

In this example, the following codes shall works fine:

obj = User.query.filter_by(id=123).one()
session.delete(obj)
session.commit()

For me in PgAdmin 4 on Mac OS High Sierra, Clicking the PostrgreSQL10 database under Servers in the left column, then the Properties tab, showed 5433 as the port under Connection. (I don't know why, because I chose 5432 during install). Anyway, I clicked the Edit icon under the Properties tab, change that to 5432, saved, and that solved the problem. Go figure.

The fastest way is to do a*a or a**2 or np.square(a) whereas np.power(a, 2) showed to be considerably slower.

np.power() allows you to use different exponents for each element if instead of 2 you pass another array of exponents. From the comments of @GarethRees I just learned that this function will give you different results than a**2 or a*a, which become important in cases where you have small tolerances.

I've timed some examples using NumPy 1.9.0 MKL 64 bit, and the results are shown below:

In [29]: a = np.random.random((1000, 1000))

In [30]: timeit a*a
100 loops, best of 3: 2.78 ms per loop

In [31]: timeit a**2
100 loops, best of 3: 2.77 ms per loop

In [32]: timeit np.power(a, 2)
10 loops, best of 3: 71.3 ms per loop

So for today, jspdf-1.5.3. To answer the question of having the pdf file page exactly same as the canvas. After many tries of different combinations, I figured you gotta do something like this. We first need to set the height and width for the output pdf file with correct orientation, otherwise the sides might be cut off. Then we get the dimensions from the 'pdf' file itself, if you tried to use the canvas's dimensions, the sides might be cut off again. I am not sure why that happens, my best guess is the jsPDF convert the dimensions in other units in the library.

  // Download button
  $("#download-image").on('click', function () {
    let width = __CANVAS.width; 
    let height = __CANVAS.height;

    //set the orientation
    if(width > height){
      pdf = new jsPDF('l', 'px', [width, height]);
    }
    else{
      pdf = new jsPDF('p', 'px', [height, width]);
    }
    //then we get the dimensions from the 'pdf' file itself
    width = pdf.internal.pageSize.getWidth();
    height = pdf.internal.pageSize.getHeight();
    pdf.addImage(__CANVAS, 'PNG', 0, 0,width,height);
    pdf.save("download.pdf");
  });

Learnt about switching orientations from here: https://github.com/MrRio/jsPDF/issues/476

Like docs say:

When the command line does not specify where to push with the <repository> argument, branch.*.remote configuration for the current branch is consulted to determine where to push. If the configuration is missing, it defaults to origin.

Lists themselves are thread-safe. In CPython the GIL protects against concurrent accesses to them, and other implementations take care to use a fine-grained lock or a synchronized datatype for their list implementations. However, while lists themselves can't go corrupt by attempts to concurrently access, the lists's data is not protected. For example:

L[0] += 1

is not guaranteed to actually increase L[0] by one if another thread does the same thing, because += is not an atomic operation. (Very, very few operations in Python are actually atomic, because most of them can cause arbitrary Python code to be called.) You should use Queues because if you just use an unprotected list, you may get or delete the wrong item because of race conditions.

In case this can help anyone, here's simple CSS as a jumping off point. Turns it into a basic rounded square big enough for thumbs with a toggled background color.

input[type='checkbox'] {_x000D_
    -webkit-appearance:none;_x000D_
    width:30px;_x000D_
    height:30px;_x000D_
    background:white;_x000D_
    border-radius:5px;_x000D_
    border:2px solid #555;_x000D_
}_x000D_
input[type='checkbox']:checked {_x000D_
    background: #abd;_x000D_
}

<input type="checkbox" />

jQuery is just a library which enhances the capabilities of the DOM within a web browser; the underlying language is JavaScript, which has, as you might hope to expect from a programming language, the ability to perform conditional logic, i.e.

if( condition ) {
    // do something
}

Testing two conditions is straightforward, too:

if( A && B ) {
    // do something
}

Dear God, I hope this isn't a troll...

However, you should also read Elias Mårtenson's answer on Android plurals treatment of “zero”. There is a problem with the interpretation of certain values such as "zero".

For me - here is a less confusing way of doing the socket.setTimeout

var request=require('https').get(
    url
   ,function(response){
        var r='';
        response.on('data',function(chunk){
            r+=chunk;
            });
        response.on('end',function(){
            console.dir(r);            //end up here if everything is good!
            });
        }).on('error',function(e){
            console.dir(e.message);    //end up here if the result returns an error
            });
request.on('error',function(e){
    console.dir(e);                    //end up here if a timeout
    });
request.on('socket',function(socket){
    socket.setTimeout(1000,function(){
        request.abort();                //causes error event ?
        });
    });

There is this MarkerClusterer client side utility available for google Map as specified here on Google Map developer Articles, here is brief on what's it's usage:

There are many approaches for doing what you asked for:

• Grid based clustering
• Distance based clustering
• Viewport Marker Management
• Fusion Tables
• Marker Clusterer
• MarkerManager

You can read about them on the provided link above.

Marker Clusterer uses Grid Based Clustering to cluster all the marker wishing the grid. Grid-based clustering works by dividing the map into squares of a certain size (the size changes at each zoom) and then grouping the markers into each grid square.

After Clustering

I hope this is what you were looking for & this will solve your problem :)

You want to install a downloaded wheel (.whl) file on Python under Windows?

1. Install pip on your Python(s) on Windows (on Python 3.4+ it is already included)

2. Upgrade pip if necessary (on the command line)

   pip install -U pip
   

3. Install a local wheel file using pip (on the command line)

   pip install --no-index --find-links=LocalPathToWheelFile PackageName
   

Option --no-index tells pip to not look on pypi.python.org (which would fail for many packages if you have no compiler installed), --find-links then tells pip where to look for instead. PackageName is the name of the package (numpy, scipy, .. first part or whole of wheel file name). For more informations see the install options of pip.

You can execute these commands in the command prompt when switching to your Scripts folder of your Python installation.

Example:

cd C:\Python27\Scripts
pip install -U pip
pip install --no-index --find-links=LocalPathToWheelFile PackageName

Note: It can still be that the package does not install on Windows because it may contain C/C++ source files which need to be compiled. You would need then to make sure a compiler is installed. Often searching for alternative pre-compiled distributions is the fastest way out.

For example numpy-1.9.2+mkl-cp27-none-win_amd64.whl has PackageName numpy.

Here is the best practice: https://github.com/PillowPillow/ng2-webstorage

I was use it in AngularJs, now with Angular2. Wery usefull.

In Bash, if you have set noclobber a la set -o noclobber, then you use the syntax >|

For example:

echo "some text" >| existing_file

This also works if the file doesn't exist yet

• Check if noclobber is set with: set -o | grep noclobber

• For a more detailed explanation on this special type of operator, see this post

• For a more exhaustive list of redirection operators, refer to this post

By far the best tool I have used for reverse engineering, and round tripping java -> UML is Borland's Together. It is based on Eclipse (not just a single plugin) and really works well.

I had the same problem on Mac OS Try to run sudo mongod and in a new terminal tab run mongo

TL;DR: a library

I advise using something like dom-helpers, written by the react team as a regular JS lib.

In their contains implementation you will see a Node#contains based implementation with a Node#compareDocumentPosition fallback.

Support for very old browsers e.g. IE <9 would not be given, which I find acceptable.

This answer incorporates the above ones, however I would advise against looping yourself.

From the Maven Embedder documentation:

-fae,--fail-at-end Only fail the build afterwards; allow all non-impacted builds to continue

-fn,--fail-never NEVER fail the build, regardless of project result

So if you are testing one module than you are safe using -fae.

Otherwise, if you have multiple modules, and if you want all of them tested (even the ones that depend on the failing tests module), you should run mvn clean install -fn.
-fae will continue with the module that has a failing test (will run all other tests), but all modules that depend on it will be skipped.

Replace in System Sounds the "Critical Stop" to a wav-file which is silent 1.

Just removing the sound completely did not work for me. Apparently some default sound was used in this case.

(Credits for this.lau_ on SuperUser for discovering this).

SELECT only retrieves data from the database, it does not change the table itself.

If you write

SELECT a AS b FROM x

"b" is just an alias name in the query. It does not create an extra column. Your result in the example would only contain one column named "b". But the column in the table would stay "a". "b" is just another name.

I don't really understand what you mean with "so I can use it with each item later on". Do you mean later in the select statement or later in your application. Perhaps you could provide some example code.

add this to your activity

@Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
    if ((keyCode == KeyEvent.KEYCODE_BACK))
    {
        finish();
    }
    return super.onKeyDown(keyCode, event);
}

The reason the code will not work without void is because the System.out.println(String string) method returns nothing and just prints the supplied arguments to the standard out terminal, which is the computer monitor in most cases. When a method returns "nothing" you have to specify that by putting the void keyword in its signature.

You can see the documentation of the System.out.println here:

http://download.oracle.com/javase/6/docs/api/java/io/PrintStream.html#println%28java.lang.String%29

To press the issue further, println is a classic example of a method which is performing computation as a "side effect."

•   is the character entity reference (meant to be easily parseable by humans).
•   is the numeric entity reference (meant to be easily parseable by machines).

They are the same except for the fact that the latter does not need another lookup table to find its actual value. The lookup table is called a DTD, by the way.

You can read more about character entity references in the offical W3C documents.

Solution for Swift 2:

let singleTapGesture = UITapGestureRecognizer(target: self, action: #selector(handleSingleTap))
singleTapGesture.numberOfTapsRequired = 1 // Optional for single tap
view.addGestureRecognizer(singleTapGesture)

let doubleTapGesture = UITapGestureRecognizer(target: self, action: #selector(handleDoubleTap))
doubleTapGesture.numberOfTapsRequired = 2
view.addGestureRecognizer(doubleTapGesture)

singleTapGesture.requireGestureRecognizerToFail(doubleTapGesture)

If you want to be able to have a SELECT without problems of the parent id having to be lower than child id, a function could be used. It supports also multiple children (as a tree should do) and the tree can have multiple heads. It also ensure to break if a loop exists in the data.

I wanted to use dynamic SQL to be able to pass the table/columns names, but functions in MySQL don't support this.

DELIMITER $$

CREATE FUNCTION `isSubElement`(pParentId INT, pId INT) RETURNS int(11)
DETERMINISTIC    
READS SQL DATA
BEGIN
DECLARE isChild,curId,curParent,lastParent int;
SET isChild = 0;
SET curId = pId;
SET curParent = -1;
SET lastParent = -2;

WHILE lastParent <> curParent AND curParent <> 0 AND curId <> -1 AND curParent <> pId AND isChild = 0 DO
    SET lastParent = curParent;
    SELECT ParentId from `test` where id=curId limit 1 into curParent;

    IF curParent = pParentId THEN
        SET isChild = 1;
    END IF;
    SET curId = curParent;
END WHILE;

RETURN isChild;
END$$

Here, the table test has to be modified to the real table name and the columns (ParentId,Id) may have to be adjusted for your real names.

Usage :

SET @wantedSubTreeId = 3;
SELECT * FROM test WHERE isSubElement(@wantedSubTreeId,id) = 1 OR ID = @wantedSubTreeId;

Result :

3   7   k
5   3   d
9   3   f
1   5   a

SQL for test creation :

CREATE TABLE IF NOT EXISTS `test` (
  `Id` int(11) NOT NULL,
  `ParentId` int(11) DEFAULT NULL,
  `Name` varchar(300) NOT NULL,
  PRIMARY KEY (`Id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1;

insert into test (id, parentid, name) values(3,7,'k');
insert into test (id, parentid, name) values(5,3,'d');
insert into test (id, parentid, name) values(9,3,'f');
insert into test (id, parentid, name) values(1,5,'a');
insert into test (id, parentid, name) values(6,2,'o');
insert into test (id, parentid, name) values(2,8,'c');

EDIT : Here is a fiddle to test it yourself. It forced me to change the delimiter using the predefined one, but it works.

I know this is absolutely not the right way to do it, yet it've helped me a few times in the past to get the approx object file size:

Write your object/response to the console or a new tab, copy the results to a new notepad file, save it, and check the file size. The notepad file itself is just a few bytes, so you'll get a fairly accurate object file size.

I got one good solution. Here I have attached it as the image below. So try it. It may be helpful to you...!

In my case, i had opened Pycharm in sudo mode, and was running pip install nltk in pycharm terminal which showed this error. running with sudo pip install solves the error.

I'm not a 100% sure, but won't

$(data)

produce a jquery object with a DOM for that data, not connected anywhere? Or if it's already parsed as a DOM, you could just go $("#myImg", data), or whatever selector suits your needs.

EDIT
Rereading your question it appears your 'data' is already a DOM, which means you could just go (assuming there's only an img in your DOM, otherwise you'll need a more precise selector)

$("img", data).attr ("src")

if you want to access the src-attribute. If your data is just text, it would probably work to do

$("img", $(data)).attr ("src")

I dont know why but this is working on my local develop and production, but other changes if i made i have to be careful because it may work local and on develop but not on production
