For US Address Parsing,

I prefer using usaddress package that is available in pip for usaddress only

python3 -m pip install usaddress

Documentation
PyPi

This worked well for me for US address.

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

# address_parser.py
import sys
from usaddress import tag
from json import dumps, loads

if __name__ == '__main__':
    tag_mapping = {
        'Recipient': 'recipient',
        'AddressNumber': 'addressStreet',
        'AddressNumberPrefix': 'addressStreet',
        'AddressNumberSuffix': 'addressStreet',
        'StreetName': 'addressStreet',
        'StreetNamePreDirectional': 'addressStreet',
        'StreetNamePreModifier': 'addressStreet',
        'StreetNamePreType': 'addressStreet',
        'StreetNamePostDirectional': 'addressStreet',
        'StreetNamePostModifier': 'addressStreet',
        'StreetNamePostType': 'addressStreet',
        'CornerOf': 'addressStreet',
        'IntersectionSeparator': 'addressStreet',
        'LandmarkName': 'addressStreet',
        'USPSBoxGroupID': 'addressStreet',
        'USPSBoxGroupType': 'addressStreet',
        'USPSBoxID': 'addressStreet',
        'USPSBoxType': 'addressStreet',
        'BuildingName': 'addressStreet',
        'OccupancyType': 'addressStreet',
        'OccupancyIdentifier': 'addressStreet',
        'SubaddressIdentifier': 'addressStreet',
        'SubaddressType': 'addressStreet',
        'PlaceName': 'addressCity',
        'StateName': 'addressState',
        'ZipCode': 'addressPostalCode',
    }
    try:
        address, _ = tag(' '.join(sys.argv[1:]), tag_mapping=tag_mapping)
    except:
        with open('failed_address.txt', 'a') as fp:
            fp.write(sys.argv[1] + '\n')
        print(dumps({}))
    else:
        print(dumps(dict(address)))

Running the address_parser.py

 python3 address_parser.py 9757 East Arcadia Ave. Saugus MA 01906
 {"addressStreet": "9757 East Arcadia Ave.", "addressCity": "Saugus", "addressState": "MA", "addressPostalCode": "01906"}

One use case is to make an ajax call before the user closes the window or leaves the page. This would be like deleting some temporary records in the database before the user can navigate to another site or closes the browser.

 $(window).unload(
        function(){
            $.ajax({
            url: 'your url',
            global: false,
            type: 'POST',
            data: {},
            async: false, //blocks window close
            success: function() {}
        });
    });

Don't know why but in my case it doesn't work the way suggested earlier. But it works like this:

Time.now.change(offset: "-3000")

Of course you need to change offset value to yours.

SOLVED - not rendering border radius correctly in IE 10 and 11

For those not getting the -ms-border-radius: or the border-radius: to work in IE 10,11 And it renders all square then follow these steps:

1. Click on the gear wheel at the top right of the IE browser
2. Click on Compatibility view settings
3. Now uncheck the 2 boxes that are checked by default.

Note in Guzzle V6.0+, another source of getting the following error may be incorrect use of JSON as an array:

Passing in the "body" request option as an array to send a POST request has been deprecated. Please use the "form_params" request option to send a application/x-www-form-urlencoded request, or a the "multipart" request option to send a multipart/form-data request.

Incorrect:

$response = $client->post('http://example.com/api', [
    'body' => [
        'name' => 'Example name',
    ]
])

Correct:

$response = $client->post('http://example.com/api', [
    'json' => [
        'name' => 'Example name',
    ]
])

Correct:

$response = $client->post('http://example.com/api', [
    'headers' => ['Content-Type' => 'application/json'],
    'body' => json_encode([
        'name' => 'Example name',
    ])
])

There's several things you can improve upon here. To start, there's no reason to use an <a> (anchor) tag since you don't have a link.

Every element can be bound to click and hover events... divs, spans, labels, inputs, etc.

I can't really identify what it is you're trying to do, though. You're mixing the goal with your own implementation and, from what I've seen so far, you're not really sure how to do it. Could you better illustrate what it is you're trying to accomplish?

== EDIT ==

The requirements are still very vague. I've implemented a very quick version of what I'm imagining you're saying ... or something close that illustrates how you might be able to do it. Left me know if I'm on the right track.

Follow these steps :

1-Command+Shift+F

2-Type : modules.xml

3-Open file

4-Remove those you get error for (the module when you get error once building project)

Good luck :)

Try using the excellent Datejs JavaScript date library (the original is no longer maintained so you may be interested in this actively maintained fork instead):

Date.today().add(-30).days(); // or...
Date.today().add({days:-30});

[Edit]

See also the excellent Moment.js JavaScript date library:

moment().subtract(30, 'days'); // or...
moment().add(-30, 'days');

The regex [^ab] will match for example 'ab ab ab ab' but not 'ab', because it will match on the string ' a' or 'b '.

What language/scenario do you have? Can you subtract results from the original set, and just match ab?

If you are using GNU grep, and are parsing input, use the '-v' flag to invert your results, returning all non-matches. Other regex tools also have a 'return nonmatch' function, too.

If I understand correctly, you want everything except for those items which contain 'ab' anywhere.

The essence of object oriented programming is encapsulating logic together with the data it operates on.

Instance methods are the logic, instance fields are the data. Together, they form an object.

public class Foo
{
    private String foo;
    public Foo(String foo){ this.foo = foo; }
    public getFoo(){ return this.foo; }

    public static void main(String[] args){
        System.out.println( getFoo() );
    }
}

What could possibly be the result of running the above program?

Without an object, there is no instance data, and while the instance methods exist as part of the class definition, they need an object instance to provide data for them.

In theory, an instance method that does not access any instance data could work in a static context, but then there isn't really any reason for it to be an instance method. It's a language design decision to allow it anyway rather than making up an extra rule to forbid it.

You could try to put a ServletFilter in front of the webservice and inspect request and response going to / returned from the service.

Although you specifically did not ask for a proxy, sometimes I find tcptrace is enough to see what goes on on a connection. It's a simple tool, no install, it does show the data streams and can write to file too.

I would like to propose a solution for numpy that worked well for me. The line

from numpy import inf
inputArray[inputArray == inf] = np.finfo(np.float64).max

substitues all infite values of a numpy array with the maximum float64 number.

Reference from http://docs.scipy.org/doc/scipy/reference/tutorial/linalg.html

..., the use of the numpy.matrix class is discouraged, since it adds nothing that cannot be accomplished with 2D numpy.ndarray objects, and may lead to a confusion of which class is being used. For example,

>>> import numpy as np
>>> from scipy import linalg
>>> A = np.array([[1,2],[3,4]])
>>> A
    array([[1, 2],
           [3, 4]])
>>> linalg.inv(A)
array([[-2. ,  1. ],
      [ 1.5, -0.5]])
>>> b = np.array([[5,6]]) #2D array
>>> b
array([[5, 6]])
>>> b.T
array([[5],
      [6]])
>>> A*b #not matrix multiplication!
array([[ 5, 12],
      [15, 24]])
>>> A.dot(b.T) #matrix multiplication
array([[17],
      [39]])
>>> b = np.array([5,6]) #1D array
>>> b
array([5, 6])
>>> b.T  #not matrix transpose!
array([5, 6])
>>> A.dot(b)  #does not matter for multiplication
array([17, 39])

scipy.linalg operations can be applied equally to numpy.matrix or to 2D numpy.ndarray objects.

Basically you will need to read the file line by line.

Then you will need to split each line by the delimiter, say a comma (CSV stands for comma-separated values), with

String[] strArr=line.split(",");

This will turn it into an array of strings which you can then manipulate, for example with

String name=strArr[0];
int yearOfBirth = Integer.valueOf(strArr[1]);
int monthOfBirth = Integer.valueOf(strArr[2]);
int dayOfBirth = Integer.valueOf(strArr[3]);
GregorianCalendar dob=new GregorianCalendar(yearOfBirth, monthOfBirth, dayOfBirth);
Student student=new Student(name, dob); //lets pretend you are creating instances of Student

You will need to do this for every line so wrap this code into a while loop. (If you don't know the delimiter just open the file in a text editor.)

Here's the briefest explanation:

A Turing Complete system means a system in which a program can be written that will find an answer (although with no guarantees regarding runtime or memory).

So, if somebody says "my new thing is Turing Complete" that means in principle (although often not in practice) it could be used to solve any computation problem.

Sometimes it's a joke... a guy wrote a Turing Machine simulator in vi, so it's possible to say that vi is the only computational engine ever needed in the world.

Use transform: rotate(90deg):

#container_2 {_x000D_
    border: 1px solid;_x000D_
    padding: .5em;_x000D_
    width: 5em;_x000D_
    height: 5em;_x000D_
    transition: .3s all;  /* rotate gradually instead of instantly */_x000D_
}_x000D_
_x000D_
#container_2:hover {_x000D_
    -webkit-transform: rotate(90deg);  /* to support Safari and Android browser */_x000D_
    -ms-transform: rotate(90deg);      /* to support IE 9 */_x000D_
    transform: rotate(90deg);_x000D_
}

<div id="container_2">This box should be rotated 90&deg; on hover.</div>

Click "Run code snippet", then hover over the box to see the effect of the transform.

Realistically, no other prefixed entries are needed. See Can I use CSS3 Transforms?

I hope this will help you

Create table :

create table users (id int,first_name varchar(10),last_name varchar(10));

Insert values into the table :

insert into users (id,first_name,last_name) values(1,'Abhishek','Anand');

How about PropertiesLoaderUtils?

Resource resource = new ClassPathResource("/my.properties");
Properties props = PropertiesLoaderUtils.loadProperties(resource);

The other answer is very complete, but here is a rule of thumb:

• call is blocking:

  call('notepad.exe')
  print('hello')  # only executed when notepad is closed
  

• Popen is non-blocking:

  Popen('notepad.exe')
  print('hello')  # immediately executed

Unless you use the <img> tag, which displays an image by itself, you will not be able to achieve this with pure CSS alone. You will also need TWO HTML elements as well - one for each picture. This is because the only way you can make an element display a picture via CSS is with the background-image property, and every element can have only one background image. Which two elements you choose and how you position them is up to you. There are many ways how you can position one HTML element above another.

Use an interval to check

You can setup an interval to keep checking if the user has scrolled then do something accordingly.

Borrowing from the great John Resig in his article.

Example:

    let didScroll = false;

    window.onscroll = () => didScroll = true;

    setInterval(() => {
        if ( didScroll ) {
            didScroll = false;
            console.log('Someone scrolled me!')
        }
    }, 250);

See live example

struct Connectivity {
    static let sharedInstance = NetworkReachabilityManager()!
    static var isConnectedToInternet:Bool {
        return self.sharedInstance.isReachable
    }
}

Now call it

if Connectivity.isConnectedToInternet{
    call_your_methods_here()
} else{
    show_alert_for_noInternet()
}

SapphireSun is quite right. You can just use lst.sort(). Python's sort implementation (TimSort) check if the list is already sorted. If so sort() will completed in linear time. Sounds like a Pythonic way to ensure a list is sorted ;)

I had the same problem, getting the message "ImportError: No module named numpy".

I'm also using anaconda and found out that I needed to add numpy to the ENV I was using. You can check the packages you have in your environment with the command:

conda list

So, when I used that command, numpy was not displayed. If that is your case, you just have to add it, with the command:

conda install numpy

After I did that, the error with the import numpy was gone

I was making mistakes like this.

@import "https://fonts.googleapis.com/css?family=Open+Sans:300,300i,400,400i,600,600i,700,700i&subset=cyrillic,cyrillic-ext,latin-ext";
@import "https://use.fontawesome.com/releases/v5.3.1/css/all.css";

It works properly this way

@import url(https://fonts.googleapis.com/css?family=Open+Sans:300,300i,400,400i,600,600i,700,700i&subset=cyrillic,cyrillic-ext,latin-ext);

It's a very old post, but if it benefits anyone, we can do something like this:

Long max=((BigInteger) Collections.max(dynamics)).longValue(); 

Object initializer

If your constructor with the parameter isn't doing anything besides setting a property, you can do this in C# 3 or better using an object initializer rather than calling a constructor (which is impossible, as has been mentioned):

public static string GetAllItems<T>(...) where T : new()
{
   ...
   List<T> tabListItems = new List<T>();
   foreach (ListItem listItem in listCollection) 
   {
       tabListItems.Add(new T() { YourPropertyName = listItem } ); // Now using object initializer
   } 
   ...
}

Using this, you can always put any constructor logic in the default (empty) constructor, too.

Activator.CreateInstance()

Alternatively, you could call Activator.CreateInstance() like so:

public static string GetAllItems<T>(...) where T : new()
{
   ...
   List<T> tabListItems = new List<T>();
   foreach (ListItem listItem in listCollection) 
   {
        object[] args = new object[] { listItem };
        tabListItems.Add((T)Activator.CreateInstance(typeof(T), args)); // Now using Activator.CreateInstance
   } 
   ...
}

Note that Activator.CreateInstance can have some performance overhead that you may want to avoid if execution speed is a top priority and another option is maintainable to you.

Just write this simple line of code :-

button.performClick();

where button is the reference variable of Button class and defined as follows:-

private Button buttonToday ;
buttonToday = (Button) findViewById(R.id.buttonToday);

That's it.

Depending on what style attributes you'd like to change you may be able to use the Paris library:

Button view = (Button) LayoutInflater.from(this).inflate(R.layout.section_button, null);
Paris.style(view).apply(R.style.YourStyle);

Many attributes like background, padding, textSize, textColor, etc. are supported.

This may not be the exact answer for the OP, but is the answer to the Title of the question: How to Update Gradle in Android Studio (AS):

• Get latest version supported by AS: http://www.gradle.org/downloads (Currently 1.9, 1.10 is NOT supported by AS yet)
• Install: Unzip to anywhere like near where AS is installed: C:\Users[username]\gradle-1.9\
• Open AS: File->Settings->Build, Execution, Deployment->Build Tools-> Gradle->Service directory path: (Change to folder you set above) ->Click ok. Status on bottom should indicate it's busy & error should be fixed. Might have to restart AS

You may use default base URL path for any server That have to used in config folder > config.php files replace you :

$config['base_url'] = 'index.php';

by this code: $config['base_url'] = "http://".$_SERVER['HTTP_HOST']; $config['base_url'] .= preg_replace('@/+$@','',dirname($_SERVER['SCRIPT_NAME'])).'/';

it's auto found your folder form any server

To animate your 3D object, use the code:

<script>

$(document).ready(function(){

    var y = 0;
setInterval(function(){
    x += 1;
    y += 1;
    var element = document.getElementById('cube');
    element.style.webkitTransform = "translateZ(-100px) rotateY("+x+"deg) rotateX("+y+"deg)"; //for safari and chrome
    element.style.MozTransform = "translateZ(-100px) rotateY("+x+"deg) rotateX("+y+"deg)"; //for firefox
},50);
//for other browsers use:   "msTransform",    "OTransform",    "transform"

});

</script>

This will works perfectly in both cases, one or multiple fields searching multiple words.

To check if the property exists and if it's null too, you can use the function property_exists().

Docs: http://php.net/manual/en/function.property-exists.php

As opposed with isset(), property_exists() returns TRUE even if the property has the value NULL.

bool property_exists ( mixed $class , string $property )

Example:

if (property_exists($testObject, $property)) {
    //do something
}

maybe not as stylish, but easier:

#!/bin/bash
log="/var/log/yourlog"
/path/to/your/script.py 2>&1 | (while read; do echo "$REPLY" >> $log; done)

You're calling writer.close(); after you've done writing to it. Once a stream is closed, it can not be written to again. Usually, the way I go about implementing this is by moving the close out of the write to method.

public void writeToFile(){
    String file_text= pedStatusText + "     " + gatesStatus + "     " + DrawBridgeStatusText;
    try {
        writer.write(file_text);
        writer.flush();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

And add a method cleanUp to close the stream.

public void cleanUp() {
     writer.close();
}

This means that you have the responsibility to make sure that you're calling cleanUp when you're done writing to the file. Failure to do this will result in memory leaks and resource locking.

EDIT: You can create a new stream each time you want to write to the file, by moving writer into the writeToFile() method..

 public void writeToFile() {
    FileWriter writer = new FileWriter("status.txt", true);
    // ... Write to the file.

    writer.close();
 }

In short, yes. I assume you're looking to parse English: for that you can use the Link Parser from Carnegie Mellon.

It is important to remember that there are many theories of syntax, that can give completely different-looking phrase structure trees; further, the trees are different for each language, and tools may not exist for those languages.

As a note for the future: if you need a sentence parsed out and tag it as linguistics (and syntax or whatnot, if that's available), someone can probably parse it out for you and guide you through it.

Swift 4:

I was having an issue with the most accepted answer, in which hiding the keyboard did not return the view all the way to the bottom of the page (only partially). This worked for me (+updated for Swift 4).

override func viewDidLoad() {
    super.viewDidLoad()
    self.hideKeyboardWhenTappedAround()
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}

@objc func keyboardWillShow(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
        if self.view.frame.origin.y == 0{
            self.view.frame.origin.y -= keyboardSize.height
        }
    }
}

@objc func keyboardWillHide(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
        if self.view.frame.origin.y != 0{
            self.view.frame.origin.y = 0
        }
    }
}

I don't know if you've run into the same problem than me on MySQL Workbench but running the query with the INNER JOIN after the FROM statement didn't work for me. I was unable to run the query because the program complained about the FROM statement.

So in order to make the query work I changed it to

UPDATE table1 INNER JOIN table2 on table1.column1 = table2.column1
SET table1.column2 = table2.column4
WHERE table1.column3 = 'randomCondition';

instead of

UPDATE a
FROM table1 a INNER JOIN table2 b on a.column1 = b.column1
SET a.column2 = b.column4
WHERE a.column3 = 'randomCondition';

I guess my solution is the right syntax for MySQL.

In bootstrap 3 the format is

col-md-6 col-md-offset-3

For the same grid in Bootstrap 4 the format is

col-md-6 offset-md-3

To see the index for a specific table use SHOW INDEX:

SHOW INDEX FROM yourtable;

To see indexes for all tables within a specific schema you can use the STATISTICS table from INFORMATION_SCHEMA:

SELECT DISTINCT
    TABLE_NAME,
    INDEX_NAME
FROM INFORMATION_SCHEMA.STATISTICS
WHERE TABLE_SCHEMA = 'your_schema';

Removing the where clause will show you all indexes in all schemas.

I have to admit I'd do something rather insane.

1. Find a CPU bottleneck and extract it to a P/Invokeable DLL file.
2. As a post build action, encrypt part of the DLL file with an XOR encryption key.
3. Select a public/private key scheme, include public key in the DLL file
4. Arrange so that decrypting the product key and XORing the two halves together results in the encryption key for the DLL.
5. In the DLL's DllMain code, disable protection (PAGE_EXECUTE_READWRITE) and decrypt it with the key.
6. Make a LicenseCheck() method that makes a sanity check of the license key and parameters, then checksums entire DLL file, throwing license violation on either. Oh, and do some other initialization here.

When they find and remove the LicenseCheck, what fun will follow when the DLL starts segmentation faulting.

If you are not giving any modifier to your method then as default it will be Default modifier which has scope within package.

And if you compiler does not support Return Value Optimization, ditch it, it probably does not contain much optimization at all...

Set by definition is not ordered.

You probably use wrong collection.

Just a minor addition: if you add the -c flag to ps, you don't need to remove the line containing the grep process with grep -v afterwards. I.e.

ps acux | grep cron

is all the typing you'll need on a bsd-ish system (this includes MacOSX) You can leave the -u away if you need less information.

On a system where the genetics of the native ps command point back to SysV, you'd use

ps -e |grep cron

or

ps -el |grep cron 

for a listing containing more than just pid and process name. Of course you could select the specific fields to print out using the -o <field,field,...> option.

In C++11, the using keyword when used for type alias is identical to typedef.

7.1.3.2

A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.

Bjarne Stroustrup provides a practical example:

typedef void (*PFD)(double);    // C style typedef to make `PFD` a pointer to a function returning void and accepting double
using PF = void (*)(double);    // `using`-based equivalent of the typedef above
using P = [](double)->void; // using plus suffix return type, syntax error
using P = auto(double)->void // Fixed thanks to DyP

Pre-C++11, the using keyword can bring member functions into scope. In C++11, you can now do this for constructors (another Bjarne Stroustrup example):

class Derived : public Base { 
public: 
    using Base::f;    // lift Base's f into Derived's scope -- works in C++98
    void f(char);     // provide a new f 
    void f(int);      // prefer this f to Base::f(int) 

    using Base::Base; // lift Base constructors Derived's scope -- C++11 only
    Derived(char);    // provide a new constructor 
    Derived(int);     // prefer this constructor to Base::Base(int) 
    // ...
}; 

Ben Voight provides a pretty good reason behind the rationale of not introducing a new keyword or new syntax. The standard wants to avoid breaking old code as much as possible. This is why in proposal documents you will see sections like Impact on the Standard, Design decisions, and how they might affect older code. There are situations when a proposal seems like a really good idea but might not have traction because it would be too difficult to implement, too confusing, or would contradict old code.

Here is an old paper from 2003 n1449. The rationale seems to be related to templates. Warning: there may be typos due to copying over from PDF.

First let’s consider a toy example:

template <typename T>
class MyAlloc {/*...*/};

template <typename T, class A>
class MyVector {/*...*/};

template <typename T>

struct Vec {
typedef MyVector<T, MyAlloc<T> > type;
};
Vec<int>::type p; // sample usage

The fundamental problem with this idiom, and the main motivating fact for this proposal, is that the idiom causes the template parameters to appear in non-deducible context. That is, it will not be possible to call the function foo below without explicitly specifying template arguments.

template <typename T> void foo (Vec<T>::type&);

So, the syntax is somewhat ugly. We would rather avoid the nested ::type We’d prefer something like the following:

template <typename T>
using Vec = MyVector<T, MyAlloc<T> >; //defined in section 2 below
Vec<int> p; // sample usage

Note that we specifically avoid the term “typedef template” and introduce the new syntax involving the pair “using” and “=” to help avoid confusion: we are not defining any types here, we are introducing a synonym (i.e. alias) for an abstraction of a type-id (i.e. type expression) involving template parameters. If the template parameters are used in deducible contexts in the type expression then whenever the template alias is used to form a template-id, the values of the corresponding template parameters can be deduced – more on this will follow. In any case, it is now possible to write generic functions which operate on Vec<T> in deducible context, and the syntax is improved as well. For example we could rewrite foo as:

template <typename T> void foo (Vec<T>&);

We underscore here that one of the primary reasons for proposing template aliases was so that argument deduction and the call to foo(p) will succeed.

The follow-up paper n1489 explains why using instead of using typedef:

It has been suggested to (re)use the keyword typedef — as done in the paper [4] — to introduce template aliases:

template<class T> 
    typedef std::vector<T, MyAllocator<T> > Vec;

That notation has the advantage of using a keyword already known to introduce a type alias. However, it also displays several disavantages among which the confusion of using a keyword known to introduce an alias for a type-name in a context where the alias does not designate a type, but a template; Vec is not an alias for a type, and should not be taken for a typedef-name. The name Vec is a name for the family std::vector< [bullet] , MyAllocator< [bullet] > > – where the bullet is a placeholder for a type-name. Consequently we do not propose the “typedef” syntax. On the other hand the sentence

template<class T>
    using Vec = std::vector<T, MyAllocator<T> >;

can be read/interpreted as: from now on, I’ll be using Vec<T> as a synonym for std::vector<T, MyAllocator<T> >. With that reading, the new syntax for aliasing seems reasonably logical.

I think the important distinction is made here, aliases instead of types. Another quote from the same document:

An alias-declaration is a declaration, and not a definition. An alias- declaration introduces a name into a declarative region as an alias for the type designated by the right-hand-side of the declaration. The core of this proposal concerns itself with type name aliases, but the notation can obviously be generalized to provide alternate spellings of namespace-aliasing or naming set of overloaded functions (see ? 2.3 for further discussion). [My note: That section discusses what that syntax can look like and reasons why it isn't part of the proposal.] It may be noted that the grammar production alias-declaration is acceptable anywhere a typedef declaration or a namespace-alias-definition is acceptable.

Summary, for the role of using:

• template aliases (or template typedefs, the former is preferred namewise)
• namespace aliases (i.e., namespace PO = boost::program_options and using PO = ... equivalent)
• the document says A typedef declaration can be viewed as a special case of non-template alias-declaration. It's an aesthetic change, and is considered identical in this case.
• bringing something into scope (for example, namespace std into the global scope), member functions, inheriting constructors

It cannot be used for:

int i;
using r = i; // compile-error

Instead do:

using r = decltype(i);

Naming a set of overloads.

// bring cos into scope
using std::cos;

// invalid syntax
using std::cos(double);

// not allowed, instead use Bjarne Stroustrup function pointer alias example
using test = std::cos(double);

Add position: relative to .outside. (https://developer.mozilla.org/en-US/docs/CSS/position)

Elements that are positioned relatively are still considered to be in the normal flow of elements in the document. In contrast, an element that is positioned absolutely is taken out of the flow and thus takes up no space when placing other elements. The absolutely positioned element is positioned relative to nearest positioned ancestor. If a positioned ancestor doesn't exist, the initial container is used.

The "initial container" would be <body>, but adding the above makes .outside positioned.

I think something like:

function ReplaceContentInContainer(klass,content) {
var elems = document.getElementsByTagName('*');
for (i in elems){
    if(elems[i].getAttribute('class') == klass || elems[i].getAttribute('className') == klass){
        elems[i].innerHTML = content;
    }
}
}

would work

Seems that there's enough variation that people go out of their way to allow conversion from all conventions to others: http://www.cowtowncoder.com/blog/archives/cat_json.html

Notably, the mentioned Jackson JSON parser prefers bean_naming.

Chr(10) is the Line Feed character and Chr(13) is the Carriage Return character.

You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.

Historically, Line Feed would move down a line but not return to column 1:

This  
    is  
        a  
            test.

Similarly Carriage Return would return to column 1 but not move down a line:

This  
is  
a  
test.

Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.

Even better!

    jQuery( "#dialog" ).attr('title', 'Error');
    jQuery( "#dialog" ).text('You forgot to enter your first name');

I find that if I specify .row:nth-of-type(..), my other row's elements (for other formatting, etc) also get alternating colours. So rather, I'd define in my css an entirely new class:

.row-striped:nth-of-type(odd){
  background-color: #efefef;
}

.row-striped:nth-of-type(even){
  background-color: #ffffff;
}

So now, the alternating row colours will only apply to the row container, when I specify its class as .row-striped, and not the elements inside the row.

<!-- this entire row container is #efefef -->
<div class="row row-striped">
    <div class="form-group">
        <div class="col-sm-8"><h5>Field Greens with strawberry vinegrette</h5></div>
        <div class="col-sm-4">
            <input type="number" type="number" step="1" min="0"></input><small>$30/salad</small>
        </div>
    </div>
</div>

<!-- this entire row container is #ffffff -->
<div class="row row-striped">
    <div class="form-group">
        <div class="col-sm-8"><h5>Greek Salad</h5></div>
        <div class="col-sm-4">
            <input type="number" type="number" step="1" min="0"></input><small>$25/salad</small>
        </div>
    </div>
</div>

for windows, if you want global config, then run

git config --global http.sslVerify false

If you want to replace a char in a string with an empty char that means you want to remove that char from a string, read the answer of R. Martinho Fernandes.

Here is an exemple of how to remove a char from a string (replace with an "Empty char"):

    public static string RemoveCharFromString(string input, char charItem)
    {
        int indexOfChar = input.IndexOf(charItem);
        if (indexOfChar >= 0)
        {
            input = input.Remove(indexOfChar, 1);
        }
        return input;
    }

or this version that removes all recurrences of a char in a string :

    public static string RemoveCharFromString(string input, char charItem)
    {
        int indexOfChar = input.IndexOf(charItem);
        if (indexOfChar < 0)
        {
            return input;
        }
        return RemoveCharFromString(input.Remove(indexOfChar, 1), charItem);
    }

What about

$.ajax({
  type: 'POST',
  url: $("form").attr("action"),
  data: $("form").serialize(), 
  //or your custom data either as object {foo: "bar", ...} or foo=bar&...
  success: function(response) { ... },
});

You need to append to the first list those elements of the second list that aren't in the first - sets are the easiest way of determining which elements they are, like this:

first_list = [1, 2, 2, 5]
second_list = [2, 5, 7, 9]

in_first = set(first_list)
in_second = set(second_list)

in_second_but_not_in_first = in_second - in_first

result = first_list + list(in_second_but_not_in_first)
print(result)  # Prints [1, 2, 2, 5, 9, 7]

Or if you prefer one-liners 8-)

print(first_list + list(set(second_list) - set(first_list)))

TL;DR Check the network mode of your VirtualBox host - it should be bridged if you want the virtual machine (and the Docker container it's hosting) accessible on your local network.

It sounds like your confusion lies in which host to connect to in order to access your application via HTTP. You haven't really spelled out what your configuration is - I'm going to make some guesses, based on the fact that you've got "Windows" and "VirtualBox" in your tags.

I'm guessing that you have Docker running on some flavour of Linux running in VirtualBox on a Windows host. I'm going to label the IP addresses as follows:

D = the IP address of the Docker container

L = the IP address of the Linux host running in VirtualBox

W = the IP address of the Windows host

When you run your Go application on your Windows host, you can connect to it with http://W:8080/ from anywhere on your local network. This works because the Go application binds the port 8080 on the Windows machine and anybody who tries to access port 8080 at the IP address W will get connected.

And here's where it becomes more complicated:

VirtualBox, when it sets up a virtual machine (VM), can configure the network in one of several different modes. I don't remember what all the different options are, but the one you want is bridged. In this mode, VirtualBox connects the virtual machine to your local network as if it were a stand-alone machine on the network, just like any other machine that was plugged in to your network. In bridged mode, the virtual machine appears on your network like any other machine. Other modes set things up differently and the machine will not be visible on your network.

So, assuming you set up networking correctly for the Linux host (bridged), the Linux host will have an IP address on your local network (something like 192.168.0.x) and you will be able to access your Docker container at http://L:8080/.

If the Linux host is set to some mode other than bridged, you might be able to access from the Windows host, but this is going to depend on exactly what mode it's in.

EDIT - based on the comments below, it sounds very much like the situation I've described above is correct.

Let's back up a little: here's how Docker works on my computer (Ubuntu Linux).

Imagine I run the same command you have: docker run -p 8080:8080 dockertest. What this does is start a new container based on the dockertest image and forward (connect) port 8080 on the Linux host (my PC) to port 8080 on the container. Docker sets up it's own internal networking (with its own set of IP addresses) to allow the Docker daemon to communicate and to allow containers to communicate with one another. So basically what you're doing with that -p 8080:8080 is connecting Docker's internal networking with the "external" network - ie. the host's network adapter - on a particular port.

With me so far? OK, now let's take a step back and look at your system. Your machine is running Windows - Docker does not (currently) run on Windows, so the tool you're using has set up a Linux host in a VirtualBox virtual machine. When you do the docker run in your environment, exactly the same thing is happening - port 8080 on the Linux host is connected to port 8080 on the container. The big difference here is that your Windows host is not the Linux host on which the container is running, so there's another layer here and it's communication across this layer where you are running into problems.

What you need is one of two things:

1. to connect port 8080 on the VirtualBox VM to port 8080 on the Windows host, just like you connect the Docker container to the host port.

2. to connect the VirtualBox VM directly to your local network with the bridged network mode I described above.

If you go for the first option, you will be able to access the container at http://W:8080 where W is the IP address or hostname of the Windows host. If you opt for the second, you will be able to access the container at http://L:8080 where L is the IP address or hostname of the Linux VM.

So that's all the higher-level explanation - now you need to figure out how to change the configuration of the VirtualBox VM. And here's where I can't really help you - I don't know what tool you're using to do all this on your Windows machine and I'm not at all familiar with using Docker on Windows.

If you can get to the VirtualBox configuration window, you can make the changes described below. There is also a command line client that will modify VMs, but I'm not familiar with that.

For bridged mode (and this really is the simplest choice), shut down your VM, click the "Settings" button at the top, and change the network mode to bridged, then restart the VM and you're good to go. The VM should pick up an IP address on your local network via DHCP and should be visible to other computers on the network at that IP address.

You can't call something on the entire viewModel, but on an individual observable you can call myObservable.valueHasMutated() to notify subscribers that they should re-evaluate. This is generally not necessary in KO, as you mentioned.

In my case the problem was solved by Window -> Preferences -> Maven -> User Settings -> Update Settings. I don't know the problem cause at the first place.

Hashtables are not inherently sorted, your best bet is to use another structure such as a SortedList or an ArrayList

You can also use the sc tool to set it.

You can also call it from PowerShell and add additional checks if needed. The advantage of this tool vs. PowerShell is that the sc tool can also set the start type to auto delayed.

# Get Service status
$Service = "Wecsvc"
sc.exe qc $Service

# Set Service status
$Service = "Wecsvc"
sc.exe config $Service start= delayed-auto

const in C++ does not mean that a value is a constant.

const in C++ implies that the client of a contract undertakes not to alter its value.

Whether the value of a const expression changes becomes more evident if you are in an environment which supports thread based concurrency.

As Java was designed from the start to support thread and lock concurrency, it didn't add to confusion by overloading the term to have the semantics that final has.

eg:

#include <iostream>

int main ()
{
    volatile const int x = 42;

    std::cout << x << std::endl;

    *const_cast<int*>(&x) = 7;

    std::cout << x << std::endl;

    return 0;
}

outputs 42 then 7.

Although x marked as const, as a non-const alias is created, x is not a constant. Not every compiler requires volatile for this behaviour (though every compiler is permitted to inline the constant)

With more complicated systems you get const/non-const aliases without use of const_cast, so getting into the habit of thinking that const means something won't change becomes more and more dangerous. const merely means that your code can't change it without a cast, not that the value is constant.

HTML are markup languages, basically they are set of tags like <html>, <body>, which is used to present a website using css, and javascript as a whole. All these, happen in the clients system or the user you will be browsing the website.

Now, Connecting to a database, happens on whole another level. It happens on server, which is where the website is hosted.

So, in order to connect to the database and perform various data related actions, you have to use server-side scripts, like php, jsp, asp.net etc.

Now, lets see a snippet of connection using MYSQLi Extension of PHP

$db = mysqli_connect('hostname','username','password','databasename');

This single line code, is enough to get you started, you can mix such code, combined with HTML tags to create a HTML page, which is show data based pages. For example:

<?php
    $db = mysqli_connect('hostname','username','password','databasename');
?>
<html>
    <body>
          <?php
                $query = "SELECT * FROM `mytable`;";
                $result = mysqli_query($db, $query);
                while($row = mysqli_fetch_assoc($result)) {
                      // Display your datas on the page
                }
          ?>
    </body>
</html>

In order to insert new data into the database, you can use phpMyAdmin or write a INSERT query and execute them.

You probably did not install MySQL via yum? The version of MySQLDB in the repository is tied to the version of MySQL in the repository. The versions need to match.

Your choices are:

1. Install the RPM version of MySQL.
2. Compile MySQLDB to your version of MySQL.

Functions are computed values and cannot perform permanent environmental changes to SQL Server (i.e., no INSERT or UPDATE statements allowed).

A function can be used inline in SQL statements if it returns a scalar value or can be joined upon if it returns a result set.

A point worth noting from comments, which summarize the answer. Thanks to @Sean K Anderson:

Functions follow the computer-science definition in that they MUST return a value and cannot alter the data they receive as parameters (the arguments). Functions are not allowed to change anything, must have at least one parameter, and they must return a value. Stored procs do not have to have a parameter, can change database objects, and do not have to return a value.

If someone wants to handle dynamic data with multiple rows, this is for handing dynamic data.

You can check if the rowId is equal to 0.

If it is equal to 0, then you can set the state of the boolean value as true.

interface MyCellRendererState {
    value: boolean;
}
constructor(props) {
        super(props);
        this.state = {
            value: props.value ? props.value : false
        };
        this.handleCheckboxChange = this.handleCheckboxChange.bind(this);
    }
handleCheckboxChange() {
        this.setState({ value: !this.state.value });
    };
render() {
        const { value } = this.state;
        const rowId = this.props.rowIndex
        if (rowId === 0) {
           this.state = {
             value : true }
        }
        return ( 
          <div onChange={this.handleCheckboxChange}>
            <input 
            type="radio" 
            checked={this.state.value}
            name="print"
            /> 
          </div>
         )
      }

I'd use something like:

dim customer = (from c in xmldoc...<Customer> 
                where c.<ID>.Value=22 
                select c).SingleOrDefault 

Edit:

missed the c# tag, sorry......the example is in VB.NET

classic solution:

for f in $(find . -name "*dbg*"); do mv $f $(echo $f | sed 's/_dbg//'); done

Assume file is already created in the predefined directory with name "table.txt"

• 1) change the ownership for file :

  sudo chown username:username table.txt
  

• 2) change the mode of the file

  sudo chmod 777 table.txt
  

Now, try it should work!

If you don't mind using the Variant data type, then you can use the in-built worksheet function Unique as shown.

sub unique_results_to_array()
    dim rng_data as Range
    set rng_data = activesheet.range("A1:A10") 'enter the range of data here

    dim my_arr() as Variant
    my_arr = WorksheetFunction.Unique(rng_data)
    
    first_val  = my_arr(1,1)
    second_val = my_arr(2,1)
    third_val = my_arr(3,1)   'etc...    

end sub

Update for 2017

As of Laravel 5.2 documented under Other response types you can now use the file helper to display a file in the user's browser.

return response()->file($pathToFile);

return response()->file($pathToFile, $headers);

Source/thanks to below answer

Outdated answer from 2014

You just need to send the contents of the file to the browser and tell it the content type rather than tell the browser to download it.

$filename = 'test.pdf';
$path = storage_path($filename);

return Response::make(file_get_contents($path), 200, [
    'Content-Type' => 'application/pdf',
    'Content-Disposition' => 'inline; filename="'.$filename.'"'
]);

If you use Response::download it automatically sets the Content-Disposition to attachment which causes the browser to download it. See this question for the differences between Content-Disposition inline and attachment.

Edit: As per the request in the comments, I should point out that you'd need to use Response at the beginning of your file in order to use the Facade.

use Response;

Or the fully qualified namespace if Response isn't aliased to Illuminate's Response Facade.

I'd go with the multiple resource files. It shouldn't be that hard to configure. In fact I recently answered a similar question on setting a global language based resource files in conjunction with form language resource files.

Localization in Visual Studio 2008

I would consider that the best approach at least for WinForm development.

The main reason you use the default queue over the main queue is to run tasks in the background.

For instance, if I am downloading a file from the internet and I want to update the user on the progress of the download, I will run the download in the priority default queue and update the UI in the main queue asynchronously.

dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void){
    //Background Thread
    dispatch_async(dispatch_get_main_queue(), ^(void){
        //Run UI Updates
    });
});

Oh, youngsters.... Here you are:

<div class="block">
    <a href="#">Some Content with a very long description. Could be a Loren Ipsum or something like that.</a>
    <span>
        <span class="r-b">A right-bottom-block with some information</span>
    </span>
    <span class="clearfix"></span>
</div>
<style>
    .block {
        border: #000 solid 1px;
    }

    .r-b {
        border: #f00 solid 1px;
        background-color: fuchsia;
        float: right;
        width: 33%
    }

    .clearfix::after {
        display: block;
        clear: both;
        content: "";
    }
</style>

Use this XPath expression:

/*/*/X/node()

This selects any node (element, text node, comment or processing instruction) that is a child of any X element that is a grand-child of the top element of the XML document.

To verify what is selected, here is this XSLT transformation that outputs exactly the selected nodes:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes"/>
 <xsl:template match="/">
  <xsl:copy-of select="/*/*/X/node()"/>
 </xsl:template>
</xsl:stylesheet>

and it produces exactly the wanted, correct result:

   First Text Node #1            
    <y> Y can Have Child Nodes #                
        <child> deep to it </child>
    </y>            Second Text Node #2 
    <z />

Explanation:

1. As defined in the W3 XPath 1.0 Spec, "child::node() selects all the children of the context node, whatever their node type." This means that any element, text-node, comment-node and processing-instruction node children are selected by this node-test.

2. node() is an abbreviation of child::node() (because child:: is the primary axis and is used when no axis is explicitly specified).

StreamWriter is available for NET 1.1. and for the Compact framework. Just open the file and apply the ToString to your StringBuilder:

    StringBuilder sb = new StringBuilder();
    sb.Append(......);

    StreamWriter sw = new StreamWriter("\\hereIAm.txt", true);
    sw.Write(sb.ToString());
    sw.Close();

Also, note that you say that you want to append debug messages to the file (like a log). In this case, the correct constructor for StreamWriter is the one that accepts an append boolean flag. If true then it tries to append to an existing file or create a new one if it doesn't exists.

Working method,

1. vi /etc/postgresql/9.3/main/pg_hba.conf
2. local all postgres peer here change peer to trust

3. restart, sudo service postgresql restart

4. now try, psql -U postgres

Take a look at launch4j

To check input type

<!DOCTYPE html>
<html>
<body>

    <input type=number id="txtinp">
    <button onclick=checktype()>Try it</button>

    <script>
        function checktype() 
        {
            alert(document.getElementById("txtinp").type);
        }
    </script>

</body>
</html> 

You can use a JS and SCSS/Fontawesome combination for the Prev/Next buttons.

In your JS (this includes screenreader only/accessibility classes with Zurb Foundation):

$('.whatever-carousel').owlCarousel({
    ... ...
    navText: ["<span class='show-for-sr'>Previous</span>","<span class='show-for-sr'>Next</span>"]
    ... ...
})

In your SCSS this:

.owl-theme {

    .owl-nav {
        .owl-prev,
        .owl-next {
            font-family: FontAwesome;
            //border-radius: 50%;
            //padding: whatever-to-get-a-circle;
            transition: all, .2s, ease;
        }
        .owl-prev {
            &::before {
                content: "\f104";
            }
        }
        .owl-next {
            &::before {
                content: "\f105";
            }
        }
    }
}

For the FontAwesome font-family I happen to use the embed code in the document header:

<script src="//use.fontawesome.com/123456whatever.js"></script>

There are various ways to include FA, strokes/folks, but I find this is pretty fast and as I'm using webpack I can just about live with that 1 extra js server call.

And to update this - there's also this JS option for slightly more complex arrows, still with accessibility in mind:

$('.whatever-carousel').owlCarousel({
    navText: ["<span class=\"fa-stack fa-lg\" aria-hidden=\"true\"><span class=\"show-for-sr\">Previous</span><i class=\"fa fa-circle fa-stack-2x\"></i><i class=\"fa fa-chevron-left fa-stack-1x fa-inverse\" aria-hidden=\"true\"></i></span>","<span class=\"fa-stack fa-lg\" aria-hidden=\"true\"><span class=\"show-for-sr\">Next</span><i class=\"fa fa-circle fa-stack-2x\"></i><i class=\"fa fa-chevron-right fa-stack-1x fa-inverse\" aria-hidden=\"true\"></i></span>"]
})

Loads of escaping there, use single quotes instead if preferred.

And in the SCSS just comment out the ::before attrs:

.owl-prev {
        //&::before { content: "\f104"; }
    }
    .owl-next {
        //&::before { content: "\f105"; }
    }

Because I can not comment to @Michelle 's answer, I post my trick here.

Instead of checking the version on meta tag that usually is removed by a customized theme.

Check the rss feed by append /feed to almost any link from that site, then search for some keywords (wordpress, generator), you will have a better chance.

I'm going to test adding the no-store tag to our site to see if this makes a difference to browser caching (Chrome has sometimes been caching the pages). I also found this article very useful on documentation on how and why caching works and will look at ETag's next if the no-store is not reliable:

http://www.mnot.net/cache_docs/

i was trying the same, so i downloaded the .7zip version of XAMPP with php 5.6.33 from https://sourceforge.net/projects/xampp/files/XAMPP%20Windows/5.6.33/

then followed the steps below: 1. rename c:\xampp\php to c:\xampp\php7 2. raname C:\xampp\apache\conf\extra\httpd-xampp.conf to httpd-xampp7.OLD 3. copy php folder from XAMPP_5.6 7zip archive to c:\xampp\ 4. copy file httpd-xampp.conf from XAMPP_5.6 7zip archive to C:\xampp\apache\conf\extra\

open xampp control panel and start Apache and then visit ( i am using port 82 instead of default 80) http://localhost and then click PHPInfo to see if it is working as expected.

Opening localhost shows dashboard

Opening phpinfo shows version 5.6

Just use DROP TABLE IF EXISTS:

DROP TABLE IF EXISTS `foo`;
CREATE TABLE `foo` ( ... );

Try searching the MySQL documentation first if you have any other problems.

These types of arrays are known as jagged arrays in Java:

int[][] multD = new int[3][];
multD[0] = new int[3];
multD[1] = new int[2];
multD[2] = new int[5];

In this scenario each row of the array holds the different number of columns. In the above example, the first row will hold three columns, the second row will hold two columns, and the third row holds five columns. You can initialize this array at compile time like below:

 int[][] multD = {{2, 4, 1}, {6, 8}, {7, 3, 6, 5, 1}};

You can easily iterate all elements in your array:

for (int i = 0; i<multD.length; i++) {
    for (int j = 0; j<multD[i].length; j++) {
        System.out.print(multD[i][j] + "\t");
    }
    System.out.println();
}

According to what I see by using .NET Reflector:

[Serializable, ComVisible(true)]
public abstract class DictionaryBase : IDictionary, ICollection, IEnumerable
{
    // Fields
    private Hashtable hashtable;

    // Methods
    protected DictionaryBase();
    public void Clear();
.
.
.
}
Take note of these lines
// Fields
private Hashtable hashtable;

So we can be sure that DictionaryBase uses a HashTable internally.

I don't see why you are grouping here.

Try this:

var maxValue = table.Max(x => x.Status)
var result = table.First(x => x.Status == maxValue);

An alternate approach that would iterate table only once would be this:

var result = table.OrderByDescending(x => x.Status).First();

This is helpful if table is an IEnumerable<T> that is not present in memory or that is calculated on the fly.

I know it is a bit late to answer this question, but it is the first entry in google, so I think it is worth to answer it.

The problem is not a coding problem, it is an architecture problem.

You have created an interface class Event: public Item to define the methods which all events should implement. Then you have defined two types of events which inherits from class Event: public Item; Arrival and Landing and then, you have added a method Landing* createNewLanding(Arrival* arrival); from the landing functionality in the class Event: public Item interface. You should move this method to the class Landing: public Event class because it only has sense for a landing. class Landing: public Event and class Arrival: public Event class should know class Event: public Item but event should not know class Landing: public Event nor class Arrival: public Event.

I hope this helps, regards, Alberto

This is because of the proxy settings. I also had the same problem, under which I could not use any of the modules which were fetching data from the internet. There are simple steps to follow:
1. open the control panel
2. open internet options
3. under connection tab open LAN settings
4. go to advance settings and unmark everything, delete every proxy in there. Or u can just unmark the checkbox in proxy server this will also do the same
5. save all the settings by clicking ok.
you are done. try to run the programme again, it must work it worked for me at least

Step-1: Your Model class

public class RechargeMobileViewModel
    {
        public string CustomerFullName { get; set; }
        public string TelecomSubscriber { get; set; }
        public int TotalAmount { get; set; }
        public string MobileNumber { get; set; }
        public int Month { get; set; }
        public List<SelectListItem> getAllDaysList { get; set; }

        // Define the list which you have to show in Drop down List
        public List<SelectListItem> getAllWeekDaysList()
        {
            List<SelectListItem> myList = new List<SelectListItem>();
            var data = new[]{
                 new SelectListItem{ Value="1",Text="Monday"},
                 new SelectListItem{ Value="2",Text="Tuesday"},
                 new SelectListItem{ Value="3",Text="Wednesday"},
                 new SelectListItem{ Value="4",Text="Thrusday"},
                 new SelectListItem{ Value="5",Text="Friday"},
                 new SelectListItem{ Value="6",Text="Saturday"},
                 new SelectListItem{ Value="7",Text="Sunday"},
             };
            myList = data.ToList();
            return myList;
        }
}

Step-2: Call this method to fill Drop down in your controller Action

namespace MvcVariousApplication.Controllers
    {
        public class HomeController : Controller
        {
            public ActionResult Index()
            {
              RechargeMobileViewModel objModel = new RechargeMobileViewModel();
                objModel.getAllDaysList = objModel.getAllWeekDaysList();  
                return View(objModel);
            }
    }
    }

Step-3: Fill your Drop-Down List of View as follows

 @model MvcVariousApplication.Models.RechargeMobileViewModel
    @{
        ViewBag.Title = "Contact";
    }
    @Html.LabelFor(model=> model.CustomerFullName)
    @Html.TextBoxFor(model => model.CustomerFullName)

    @Html.LabelFor(model => model.MobileNumber)
    @Html.TextBoxFor(model => model.MobileNumber)

    @Html.LabelFor(model => model.TelecomSubscriber)
    @Html.TextBoxFor(model => model.TelecomSubscriber)

    @Html.LabelFor(model => model.TotalAmount)
    @Html.TextBoxFor(model => model.TotalAmount)

    @Html.LabelFor(model => model.Month)
    @Html.DropDownListFor(model => model.Month, new SelectList(Model.getAllDaysList, "Value", "Text"), "-Select Day-")

Use an interval instead of an integer:

SELECT *
FROM table
WHERE auth_user.lastactivity > CURRENT_TIMESTAMP - INTERVAL '100 days'

<> is standard ANSI SQL and stands for not equal or !=.

The pattern must have delimiters. Delimiters can be a forward slash (/) or any non alphanumeric characters(#,$,*,...). Examples

$pattern = "/My name is '(.*)' and im fine/"; 
$pattern = "#My name is '(.*)' and im fine#";
$pattern = "@My name is '(.*)' and im fine@";  

This is what you need:

import time
import datetime
n = datetime.datetime.now()
unix_time = time.mktime(n.timetuple())

This line calls the selector secondMethod after 3 seconds:

[self performSelector:@selector(secondMethod) withObject:nil afterDelay:3.0 ];

Use it on your second operation with your desired delay. If you have a lot of code, place it in its own method and call that method with performSelector:. It wont block the UI like sleep

Edit: If you do not want a second method you could add a category to be able to use blocks with performSelector:

@implementation NSObject (PerformBlockAfterDelay)

- (void)performBlock:(void (^)(void))block 
          afterDelay:(NSTimeInterval)delay
{
    block = [block copy];
    [self performSelector:@selector(fireBlockAfterDelay:) 
               withObject:block 
               afterDelay:delay];
}

- (void)fireBlockAfterDelay:(void (^)(void))block
{
    block();
}

@end

Or perhaps even cleaner:

void RunBlockAfterDelay(NSTimeInterval delay, void (^block)(void))
{
    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, NSEC_PER_SEC*delay),
      dispatch_get_current_queue(), block);
}

Sometimes, you create new application pool and cann't solve it via DCOMCNFG. Then there is another method to do:

Set the Identity (Model Name) of application pool to LocalSystem.

I don't know the root cause, but it solve my problem one time.

Hey now you can give to body background image

and set the background-position:center center;

as like this

body{
background:url('../img/some.jpg') no-repeat center center;
min-height:100%;
}

The short answer is that history.pushState (not History.pushState, which would throw an exception, the window part is optional) will never do what you suggest.

If pages are refreshing, then it is caused by other things that you are doing (for example, you might have code running that goes to a new location in the case of the address bar changing).

history.pushState({urlPath:'/page2.php'},"",'/page2.php') works exactly like it is supposed to in the latest versions of Chrome, IE and Firefox for me and my colleagues.

In fact you can put whatever you like into the function: history.pushState({}, '', 'So long and thanks for all the fish.not a real file').

If you post some more code (with special attention for code nearby the history.pushState and anywhere document.location is used), then we'll be more than happy to help you figure out where exactly this issue is coming from.

If you post more code, I'll update this answer (I have your question favourited) :).

For route controller method we have to define only one route. In get or post method we have to define the route separately.

And the resources method is used to creates multiple routes to handle a variety of Restful actions.

Here the Laravel documentation about this.

The struct module mimics C structures. It takes more CPU cycles for a processor to read a 16-bit word on an odd address or a 32-bit dword on an address not divisible by 4, so structures add "pad bytes" to make structure members fall on natural boundaries. Consider:

struct {                   11
    char a;      012345678901
    short b;     ------------
    char c;      axbbcxxxdddd
    int d;
};

This structure will occupy 12 bytes of memory (x being pad bytes).

Python works similarly (see the struct documentation):

>>> import struct
>>> struct.pack('BHBL',1,2,3,4)
'\x01\x00\x02\x00\x03\x00\x00\x00\x04\x00\x00\x00'
>>> struct.calcsize('BHBL')
12

Compilers usually have a way of eliminating padding. In Python, any of =<>! will eliminate padding:

>>> struct.calcsize('=BHBL')
8
>>> struct.pack('=BHBL',1,2,3,4)
'\x01\x02\x00\x03\x04\x00\x00\x00'

Beware of letting struct handle padding. In C, these structures:

struct A {       struct B {
    short a;         int a;
    char b;          char b;
};               };

are typically 4 and 8 bytes, respectively. The padding occurs at the end of the structure in case the structures are used in an array. This keeps the 'a' members aligned on correct boundaries for structures later in the array. Python's struct module does not pad at the end:

>>> struct.pack('LB',1,2)
'\x01\x00\x00\x00\x02'
>>> struct.pack('LBLB',1,2,3,4)
'\x01\x00\x00\x00\x02\x00\x00\x00\x03\x00\x00\x00\x04'

Python dictionaries are unordered. If you want an ordered dictionary, use collections.OrderedDict

In your case, sort the dict by key before plotting,

import matplotlib.pylab as plt

lists = sorted(d.items()) # sorted by key, return a list of tuples

x, y = zip(*lists) # unpack a list of pairs into two tuples

plt.plot(x, y)
plt.show()

Here is the result.

Edit: Although this question has been marked as a duplicate, it has still been getting attention. The answer provided by @JaKXz is correct and should be the accepted answer.

You'll need to check for the existence of the view. Then do a CREATE VIEW or ALTER VIEW depending on the result.

IF OBJECT_ID('dbo.data_VVVV') IS NULL
BEGIN
    CREATE VIEW dbo.data_VVVV
    AS
    SELECT VCV.xxxx, VCV.yyyy AS yyyy, VCV.zzzz AS zzzz FROM TABLE_A VCV
END
ELSE
    ALTER VIEW dbo.data_VVVV
    AS
    SELECT VCV.xxxx, VCV.yyyy AS yyyy, VCV.zzzz AS zzzz FROM TABLE_A VCV
BEGIN
END

simple use remove() function. and pass object as param u want to remove. ur arraylist.remove(obj)

Just wrap your WebElement into Select Object as shown below

Select dropdown = new Select(driver.findElement(By.id("identifier")));

Once this is done you can select the required value in 3 ways. Consider an HTML file like this

<html>
<body>
<select id = "designation">
<option value = "MD">MD</option>
<option value = "prog"> Programmer </option>
<option value = "CEO"> CEO </option>
</option>
</select>
<body>
</html>

Now to identify dropdown do

Select dropdown = new Select(driver.findElement(By.id("designation")));

To select its option say 'Programmer' you can do

dropdown.selectByVisibleText("Programmer ");

or

dropdown.selectByIndex(1);

or

 dropdown.selectByValue("prog");

This issue was with me also. Simple trick for it.

 @NgModule({
  imports: [
   .....       
  ],
 declarations: [
  ......
 ],

 providers: [...],
 bootstrap: [...]
 })

use it as in above order.first imports then declarations.It worked for me.

additionally for accepted answer you can use UseSubmitBehavior="false" MSDN

This worked for me:

$(window).scroll(function() {
  buffer = 40 // # of pixels from bottom of scroll to fire your function. Can be 0
  if ($(".myDiv").prop('scrollHeight') - $(".myDiv").scrollTop() <= $(".myDiv").height() + buffer )   {
    doThing();
  }
});

Must use jQuery 1.6 or higher

The best approach that I know is Eric's answer at: Get notified when UITableView has finished asking for data?

Update: To make it work I have to put these calls in -tableView:cellForRowAtIndexPath:

[tableView beginUpdates];
[tableView endUpdates];

This will not work correctly, e.g. abcÑxyz will pass thru this as it has a,b,c... you need to work with Collate or check each byte.

Intro:

Nested classes relate to other classes a little differently than outer classes. Taking Java as an example:

Non-static nested classes have access to other members of the enclosing class, even if they are declared private. Also, non-static nested classes require an instance of the parent class to be instantiated.

OuterClass outerObj = new OuterClass(arguments);
outerObj.InnerClass innerObj = outerObj.new InnerClass(arguments);

There are several compelling reasons for using them:

• It is a way of logically grouping classes that are only used in one place.

If a class is useful to only one other class, then it is logical to relate and embed it in that class and keep the two together.

• It increases encapsulation.

Consider two top-level classes, A and B, where B needs access to members of A that would otherwise be declared private. By hiding class B within class A, A's members can be declared private and B can access them. In addition, B itself can be hidden from the outside world.

• Nested classes can lead to more readable and maintainable code.

A nested class usually relates to it's parent class and together form a "package"

In PHP

You can have similar behavior in PHP without nested classes.

If all you want to achieve is structure/organization, as Package.OuterClass.InnerClass, PHP namespaces might sufice. You can even declare more than one namespace in the same file (although, due to standard autoloading features, that might not be advisable).

namespace;
class OuterClass {}

namespace OuterClass;
class InnerClass {}

If you desire to emulate other characteristics, such as member visibility, it takes a little more effort.

Defining the "package" class

            $this->publicChild->protectedMethod();
            $this->protectedChild->protectedMethod();

            echo "<br>Siblings<br>";
            $this->publicChild->callSibling($this->protectedChild);
        }
    }
}

namespace Package\MyParent
{
    class PublicChild extends \Package {
        //Makes the constructor public, hence callable from outside 
        public function __construct() {}
        protected function protectedMethod() {

        }

        protected function callSibling($sibling) {
            echo "Call from " . get_class($this) . " -> ";
            $sibling->protectedMethod();
        }
    }
    class ProtectedChild extends \Package { 
        protected function protectedMethod() {

Testing

$parent = new Package\MyParent();
$parent->test();
$pubChild = new Package\MyParent\PublicChild();//create new public child (possible)
$protChild = new Package\MyParent\ProtectedChild(); //create new protected child (ERROR)

Output:

Call from parent -> I'm Package protected method
I'm Package protected method

Siblings
Call from Package -> I'm Package protected method
Fatal error: Call to protected Package::__construct() from invalid context

NOTE:

I really don't think trying to emulate innerClasses in PHP is such a good idea. I think the code is less clean and readable. Also, there are probably other ways to achieve similar results using a well established pattern such as the Observer, Decorator ou COmposition Pattern. Sometimes, even simple inheritance is sufficient.

Or try pure ES6 nonlodash method like this

const reducer = (array, object) => {
  array.push(object.a)
  return array
}

var objects = [{ 'a': 1 }, { 'a': 2 }];
objects.reduce(reducer, [])

You can pass PHP Variables to your JavaScript by generating it with PHP:

<?php
$someVar = 1;
?>

<script type="text/javascript">
    var javaScriptVar = "<?php echo $someVar; ?>";
</script>

DefaultTableModel dm = (DefaultTableModel)table.getModel();
dm.fireTableDataChanged(); // notifies the JTable that the model has changed

You can use the NuGet Package Manager extension.

After you've installed it, to add a package, press Ctrl+Shift+P, and type >nuget and press Enter:

Type a part of your package's name as search string:

Choose the package:

And finally the package version (you probably want the newest one):

There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.

This can not have a variable:

create function Func() returns table
as
return
select 10 as ColName

You have to do like this instead:

create function Func()
returns @T table(ColName int)
as
begin
  declare @Var int
  set @Var = 10
  insert into @T(ColName) values (@Var)
  return
end

SQL Server recognizes 'TRUE' and 'FALSE' as bit values. So, use a bit data type!

declare @var bit
set @var = 'true'
print @var

That returns 1.

I find this quite tricky, but there is some information on it here at the MatPlotLib FAQ. It is rather cumbersome, and requires finding out about what space individual elements (ticklabels) take up...

Update: The page states that the tight_layout() function is the easiest way to go, which attempts to automatically correct spacing.

Otherwise, it shows ways to acquire the sizes of various elements (eg. labels) so you can then correct the spacings/positions of your axes elements. Here is an example from the above FAQ page, which determines the width of a very wide y-axis label, and adjusts the axis width accordingly:

import matplotlib.pyplot as plt
import matplotlib.transforms as mtransforms
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(range(10))
ax.set_yticks((2,5,7))
labels = ax.set_yticklabels(('really, really, really', 'long', 'labels'))

def on_draw(event):
   bboxes = []
   for label in labels:
       bbox = label.get_window_extent()
       # the figure transform goes from relative coords->pixels and we
       # want the inverse of that
       bboxi = bbox.inverse_transformed(fig.transFigure)
       bboxes.append(bboxi)

   # this is the bbox that bounds all the bboxes, again in relative
   # figure coords
   bbox = mtransforms.Bbox.union(bboxes)
   if fig.subplotpars.left < bbox.width:
       # we need to move it over
       fig.subplots_adjust(left=1.1*bbox.width) # pad a little
       fig.canvas.draw()
   return False

fig.canvas.mpl_connect('draw_event', on_draw)

plt.show()

1. Netbeans allows you to do a simple filecopy. As you know, Eclipse doesn't work like that. You must explicitly "import" files and projects.

2. If you do import, and if there are no problems, then they should show up.

3. I'd consider:

   a) making a backup of your existing workspace

   b) deleting and reinstalling Eclipse

   c) Trying another "test import"

You have to first convert your object literal to a Prototype Hash:

// Store your object literal
var obj = {foo: 1, bar: 2, barobj: {75: true, 76: false, 85: true}}

// Iterate like so.  The $H() construct creates a prototype-extended Hash.
$H(obj).each(function(pair){
  alert(pair.key);
  alert(pair.value);
});

Minimal runnable example

main.cpp

#include <cassert>

class C {
    public:
        int i;
        C(int i) : i(i) {}
        int m(int j) { return this->i + j; }
};

int main() {
    // Get a method pointer.
    int (C::*p)(int) = &C::m;

    // Create a test object.
    C c(1);
    C *cp = &c;

    // Operator .*
    assert((c.*p)(2) == 3);

    // Operator ->*
    assert((cp->*p)(2) == 3);
}

Compile and run:

g++ -ggdb3 -O0 -std=c++11 -Wall -Wextra -pedantic -o main.out main.cpp
./main.out

Tested in Ubuntu 18.04.

You cannot change the order of the parenthesis or omit them. The following do not work:

c.*p(2)
c.*(p)(2)

GCC 9.2 would fail with:

main.cpp: In function ‘int main()’:
main.cpp:19:18: error: must use ‘.*’ or ‘->*’ to call pointer-to-member function in ‘p (...)’, e.g. ‘(... ->* p) (...)’
   19 |     assert(c.*p(2) == 3);
      |

C++11 standard

.* and ->* are a single operators introduced in C++ for this purpose, and not present in C.

C++11 N3337 standard draft:

• 2.13 "Operators and punctuators" has a list of all operators, which contains .* and ->*.
• 5.5 "Pointer-to-member operators" explains what they do

If you don't mind using 3rd party libraries, AOL's cyclops-react lib, disclosure::I am a contributor, has a ExceptionSoftener class that can help here.

 s.filter(softenPredicate(a->a.isActive()));

In my case, the file ~/.curlrc had a wrong proxy configured.

EDIT Summary and reccomendations

Using a for each cell in range construct is not in itself slow. What is slow is repeated access to Excel in the loop (be it reading or writing cell values, format etc, inserting/deleting rows etc).

What is too slow depends entierly on your needs. A Sub that takes minutes to run might be OK if only used rarely, but another that takes 10s might be too slow if run frequently.

So, some general advice:

1. keep it simple at first. If the result is too slow for your needs, then optimise
2. focus on optimisation of the content of the loop
3. don't just assume a loop is needed. There are sometime alternatives
4. if you need to use cell values (a lot) inside the loop, load them into a variant array outside the loop.
5. a good way to avoid complexity with inserts is to loop the range from the bottom up
   (for index = max to min step -1)
6. if you can't do that and your 'insert a row here and there' is not too many, consider reloading the array after each insert
7. If you need to access cell properties other than value, you are stuck with cell references
8. To delete a number of rows consider building a range reference to a multi area range in the loop, then delete that range in one go after the loop

eg (not tested!)

Dim rngToDelete as range
for each rw in rng.rows
    if need to delete rw then

        if rngToDelete is nothing then
            set rngToDelete = rw
        else
            set rngToDelete = Union(rngToDelete, rw)
        end if

    endif
next
rngToDelete.EntireRow.Delete

Original post

Conventional wisdom says that looping through cells is bad and looping through a variant array is good. I too have been an advocate of this for some time. Your question got me thinking, so I did some short tests with suprising (to me anyway) results:

test data set: a simple list in cells A1 .. A1000000 (thats 1,000,000 rows)

Test case 1: loop an array

Dim v As Variant
Dim n As Long

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
v = r
For n = LBound(v, 1) To UBound(v, 1)
    'i = i + 1
    'i = r.Cells(n, 1).Value 'i + 1
Next
Debug.Print "Array Time = " & (GetTickCount - T1) / 1000#
Debug.Print "Array Count = " & Format(n, "#,###")

Result:

Array Time = 0.249 sec
Array Count = 1,000,001

Test Case 2: loop the range

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
For Each c In r
Next c
Debug.Print "Range Time = " & (GetTickCount - T1) / 1000#
Debug.Print "Range Count = " & Format(r.Cells.Count, "#,###")

Result:

Range Time = 0.296 sec
Range Count = 1,000,000

So,looping an array is faster but only by 19% - much less than I expected.

Test 3: loop an array with a cell reference

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
v = r
For n = LBound(v, 1) To UBound(v, 1)
    i = r.Cells(n, 1).Value
Next
Debug.Print "Array Time = " & (GetTickCount - T1) / 1000# & " sec"
Debug.Print "Array Count = " & Format(i, "#,###")

Result:

Array Time = 5.897 sec
Array Count = 1,000,000

Test case 4: loop range with a cell reference

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
For Each c In r
    i = c.Value
Next c
Debug.Print "Range Time = " & (GetTickCount - T1) / 1000# & " sec"
Debug.Print "Range Count = " & Format(r.Cells.Count, "#,###")

Result:

Range Time = 2.356 sec
Range Count = 1,000,000

So event with a single simple cell reference, the loop is an order of magnitude slower, and whats more, the range loop is twice as fast!

So, conclusion is what matters most is what you do inside the loop, and if speed really matters, test all the options

FWIW, tested on Excel 2010 32 bit, Win7 64 bit All tests with

• ScreenUpdating off,
• Calulation manual,
• Events disabled.

Saty described the differences between them. For your practice, you can use datetime in order to keep the output of NOW().

For example:

CREATE TABLE Orders
(
  OrderId int NOT NULL,
  ProductName varchar(50) NOT NULL,
  OrderDate datetime NOT NULL DEFAULT NOW(),
  PRIMARY KEY (OrderId)
)

You can read more at w3schools.

Normally I would recommend floating but from your 3 requirements I would suggest this:

position: absolute;
right: 10px;
top: 5px;

Don't forget position: relative; on the parent div

DEMO

Use .closest() with a selector:

var $div = $('#divid').closest('div[class^="div-a"]');

You can do this:

def active_action?(controller)
   'active' if controller.remove('/') == controller_name
end

Now, you can use like this:

<%= link_to users_path, class: "some-class #{active_action? users_path}" %>

namespace Test
{
    public partial class Member : Form
    {
        public Member()
        {
            InitializeComponent();
        }

        private bool xClicked = true;

        private void btnClose_Click(object sender, EventArgs e)
        {
            xClicked = false;
            Close();
        }

        private void Member_FormClosing(object sender, FormClosingEventArgs e)
        {
            if (xClicked)
            {
                // user click the X
            } 
            else 
            {
                // user click the close button
            }
        }
    }
}

Other answers to this question do not return what the OP needs, they will return a string like:

test1 test2 test3 test1 test3 test4

(notice that test1 and test3 are duplicated) while the OP wants to return this string:

test1 test2 test3 test4

the problem here is that the string "test1 test3" is duplicated and is inserted only once, but all of the others are distinct to each other ("test1 test2 test3" is distinct than "test1 test3", even if some tests contained in the whole string are duplicated).

What we need to do here is to split each string into different rows, and we first need to create a numbers table:

CREATE TABLE numbers (n INT);
INSERT INTO numbers VALUES
(1),(2),(3),(4),(5),(6),(7),(8),(9),(10);

then we can run this query:

SELECT
  SUBSTRING_INDEX(
    SUBSTRING_INDEX(tableName.categories, ' ', numbers.n),
    ' ',
    -1) category
FROM
  numbers INNER JOIN tableName
  ON
    LENGTH(tableName.categories)>=
    LENGTH(REPLACE(tableName.categories, ' ', ''))+numbers.n-1;

and we get a result like this:

test1
test4
test1
test1
test2
test3
test3
test3

and then we can apply GROUP_CONCAT aggregate function, using DISTINCT clause:

SELECT
  GROUP_CONCAT(DISTINCT category ORDER BY category SEPARATOR ' ')
FROM (
  SELECT
    SUBSTRING_INDEX(SUBSTRING_INDEX(tableName.categories, ' ', numbers.n), ' ', -1) category
  FROM
    numbers INNER JOIN tableName
    ON LENGTH(tableName.categories)>=LENGTH(REPLACE(tableName.categories, ' ', ''))+numbers.n-1
  ) s;

Please see fiddle here.

I'm using JUnit 5 and for me the problem was that I had imported Test from the wrong package:

import org.junit.Test;

Replacing it with the following worked for me:

import org.junit.jupiter.api.Test;

-Xmn : the size of the heap for the young generation Young generation represents all the objects which have a short life of time. Young generation objects are in a specific location into the heap, where the garbage collector will pass often. All new objects are created into the young generation region (called "eden"). When an object survive is still "alive" after more than 2-3 gc cleaning, then it will be swap has an "old generation" : they are "survivor" .

Good size is 33%

Source

works

scp localhost:"f/a\ b\ c" .

scp localhost:'f/a\ b\ c' .

does not work

scp localhost:'f/a b c' .

The reason is that the string is interpreted by the shell before the path is passed to the scp command. So when it gets to the remote the remote is looking for a string with unescaped quotes and it fails

To see this in action, start a shell with the -vx options ie bash -vx and it will display the interpolated version of the command as it runs it.

I was able to do this. I have a .child & a .parent div. The child div fits perfectly within the parent's width/height with absolute positioning. I then animate the translate property to push it's Y value down 100%. Its very smooth animation, no glitches or down sides like any other solution here.

Something like this, pseudo code

.parent{ position:relative; overflow:hidden; } 
/** shown state */
.child {
  position:absolute;top:0;:left:0;right:0;bottom:0;
  height: 100%;
  transition: transform @overlay-animation-duration ease-in-out;
  .translate(0, 0);
}

/** Animate to hidden by sliding down: */
.child.slidedown {
  .translate(0, 100%); /** Translate the element "out" the bottom of it's .scene container "mask" so its hidden */
}

You would specify a height on .parent, in px, %, or leave as auto. This div then masks out the .child div when it slides down.

I think this will help

    <directoryBrowse enabled="false" />
    <defaultDocument>
      <files>
        <clear />
        <add value="index.aspx" />
        <add value="Default.htm" />
        <add value="Default.asp" />
        <add value="index.htm" />
        <add value="index.html" />
        <add value="iisstart.htm" />

        <add value="index.php" />
      </files>

It's easy with Swift 1.2:

UIPageControl.appearance().pageIndicatorTintColor           = UIColor.lightGrayColor()
UIPageControl.appearance().currentPageIndicatorTintColor    = UIColor.redColor()

This worked for me:

npm cache clean --force 

$('#select_id').on('change', function()
{
    alert(this.value); //or alert($(this).val());
});

When you install third-party extensions you need to make sure that all the compilation parameters match:

• PHP version
• Architecture (32/64 bits)
• Compiler (VC9, VC10, VC11...)
• Thread safety

Common glitches includes:

• Editing the wrong php.ini file (that's typical with bundles); the right path is shown in phpinfo().
• Forgetting to restart Apache.

• Not being able to see the startup errors; those should show up in Apache logs, but you can also use the command line to diagnose it, e.g.:

  php -d display_startup_errors=1 -d error_reporting=-1 -d display_errors -c "C:\Path\To\php.ini" -m
  

If everything's right you should see sqlsrv in the command output and/or phpinfo() (depending on what SAPI you're configuring):

[PHP Modules]
bcmath
calendar
Core
[...]
SPL
sqlsrv
standard
[...]

There is a limit on the number of half-open connections, but afaik not for active connections. Although it appears to depend on the type of Windows 2008 server, at least according to this MSFT employee:

It depends on the edition, Web and Foundation editions have connection limits while Standard, Enterprise, and Datacenter do not.

public static String removeExtraCommas(String entry) {
    if(entry==null)
        return null;

    String ret="";
    entry=entry.replaceAll("\\s","");
    String arr[]=entry.split(",");
    boolean start=true;
    for(String str:arr) {
        if(!"".equalsIgnoreCase(str)) {
            if(start) {
                ret=str;
                start=false;
            }
            else {
            ret=ret+","+str;
            }
        }
    }               
    return ret;

}

This worked for me:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_newarea);

    btnSave = (Button)findViewById(R.id.btnSave);

    OnClickListener btnListener = new OnClickListener() {
        @Override
        public void onClick(android.view.View view) {
            finish();
        }
    };
    btnSave.setOnClickListener(btnListener);

}

Mac, In Debug mode there is a tab for the Output.

You can also take advantage of the fact that a lambda or anonymous method can close over variables in its enclosing scope.

MyType result;

SimpleUsing.DoUsing(db => 
{
  result = db.SomeQuery(); //whatever returns the MyType result
}); 

//do something with result

If you want to remove the glow from buttons in Bootstrap (which is not necessarily bad UX in my opinion), you'll need the following code:

.btn:focus, .btn:active:focus, .btn.active:focus{
  outline-color: transparent;
  outline-style: none;
}

This answer builds on the solution from @iain-elder, which works well except for the large database case (as pointed out in his solution). The entire table needs to fit in your system's memory, and for me this was not an option. I suspect the best solution would use the System.Data.SqlClient.SqlDataReader and a custom CSV serializer (see here for an example) or another language with an MS SQL driver and CSV serialization. In the spirit of the original question which was probably looking for a no dependency solution, the PowerShell code below worked for me. It is very slow and inefficient especially in instantiating the $data array and calling Export-Csv in append mode for every $chunk_size lines.

$chunk_size = 10000
$command = New-Object System.Data.SqlClient.SqlCommand
$command.CommandText = "SELECT * FROM <TABLENAME>"
$command.Connection = $connection
$connection.open()
$reader = $command.ExecuteReader()

$read = $TRUE
while($read){
    $counter=0
    $DataTable = New-Object System.Data.DataTable

You could use SysInternal's PsExec.

sudo apt-get install docker # DO NOT do this

is a different library on ubuntu.

Use sudo apt-get install docker-ce to install the correct docker.

I'm using db2 7.1 and SQuirrel. This is the only query that worked for me.

  file: path={{project_root}}/conf state=directory
- name: Copy file

An application pool is a group of one or more URLs that are served by a worker process or set of worker processes. Any Web directory or virtual directory can be assigned to an application pool.

Every application within an application pool shares the same worker process.

Also check complete.cases :

> final[complete.cases(final), ]
             gene hsap mmul mmus rnor cfam
2 ENSG00000199674    0    2    2    2    2
6 ENSG00000221312    0    1    2    3    2

na.omit is nicer for just removing all NA's. complete.cases allows partial selection by including only certain columns of the dataframe:

> final[complete.cases(final[ , 5:6]),]
             gene hsap mmul mmus rnor cfam
2 ENSG00000199674    0    2    2    2    2
4 ENSG00000207604    0   NA   NA    1    2
6 ENSG00000221312    0    1    2    3    2

Your solution can't work. If you insist on using is.na, then you have to do something like:

> final[rowSums(is.na(final[ , 5:6])) == 0, ]
             gene hsap mmul mmus rnor cfam
2 ENSG00000199674    0    2    2    2    2
4 ENSG00000207604    0   NA   NA    1    2
6 ENSG00000221312    0    1    2    3    2

but using complete.cases is quite a lot more clear, and faster.

foo = foo.Substring(0,5);

You can do this simply by using pandas drop duplicates function

df.drop_duplicates(['A','B'],keep= 'last')

Say P7 is a Cell then you can use the following Syntex to check the value of the cell and assign appropriate value to another cell based on this following nested if:

=IF(P7=0,200,IF(P7=1,100,IF(P7=2,25,IF(P7=3,10,IF((P7=4),5,0)))))

On Kotlin you can set width and height of any view directly using their virtual properties:

someView.layoutParams.width = 100
someView.layoutParams.height = 200

Agree with @Tillito, however in most cases it will foul SQL optimizer and it will not use right indexes.

It may be obvious for somebody, but I burned hours solving performance issues using Tillito solution. Lets say you have the table:

 Create table OrderDetail
    (  
       Id int primary key,
       CustomerId int references Customer(Id),
       Amount decimal default(0)
    );
 Create index ix_customer on OrderDetail(CustomerId);

and your view is something like this

 Create view CustomerView
    As
      Select 
          IsNull(CustomerId, -1) as CustomerId, -- forcing EF to use it as key
          Sum(Amount) as Amount
      From OrderDetail
      Group by CustomerId

Sql optimizer will not use index ix_customer and it will perform table scan on primary index, but if instead of:

Group by CustomerId

you use

Group by IsNull(CustomerId, -1)

it will make MS SQL (at least 2008) include right index into plan.

If

nFilter.style.width = '330px';
nFilter.style.float = 'left';

This should add an inline style to the element.

What @Darin said is what I would recommend as well. However I would add to it (and in response to one of the comments) that you can in fact also use this method for primitive types like bit, bool, even structures like Guid by simply making them nullable. Once you do this, the Required attribute functions as expected.

public UpdateViewView
{
    [Required]
    public Guid? Id { get; set; }
    [Required]
    public string Name { get; set; }
    [Required]
    public int? Age { get; set; }
    [Required]
    public bool? IsApproved { get; set; }
    //... some other properties
}

I assume X and Y are arrays? If so, there's a very simple way to do this:

x = [1, 1, 2, 4]
y = [1, 2, 2, 2]

# intersection
x & y            # => [1, 2]

# union
x | y            # => [1, 2, 4]

# difference
x - y            # => [4]

A little late reply, but what I found in Notepad++ v7.8.6 is, on RMB (Right Mouse Button), on selection text, it gives an option called "Style token" where it shows "Using 1st/2nd/3rd/4th/5th style" to highlight the selected text in different pre-defined colors

application/javascript is the correct type to use but since it's not supported by IE6-8 you're going to be stuck with text/javascript. If you don't care about validity (HTML5 excluded) then just don't specify a type.

Java does not provide a construct that will assign of multiple values to an existing array's elements. The initializer syntaxes can ONLY be used when creation a new array object. This can be at the point of declaration, or later on. But either way, the initializer is initializing a new array object, not updating an existing one.

This is now possible with C# 7.0's pattern matching. For example:

var myString = "abcDEF";

switch(myString)
{
    case string x when x.StartsWith("abc"):
        //Do something here
        break;
}

There are multiple suggestions here, but as far as I can see the jQuery UI guys have broken the dialogue control at present.

I say this because I include a dialogue on my page, and its semi transparent and the modal blanking div is behind some other elements. That can't be right!

In the end based on some other posts I developed this global solution, as an extension to the dialogue widget. It works for me but I'm not sure what it would do if I opened a dialogue from within a dialogue.

Basically it looks for the zIndex of everything else on the page and moves the .ui-widget-overlay to be one higher, and the dialogue itself to be one higher than that.

$.widget("ui.dialog", $.ui.dialog,
{
    open: function ()
    {
        var $dialog = $(this.element[0]);

        var maxZ = 0;
        $('*').each(function ()
        {
            var thisZ = $(this).css('zIndex');
            thisZ = (thisZ === 'auto' ? (Number(maxZ) + 1) : thisZ);
            if (thisZ > maxZ) maxZ = thisZ;
        });

        $(".ui-widget-overlay").css("zIndex", (maxZ + 1));
        $dialog.parent().css("zIndex", (maxZ + 2));

        return this._super();
    }
});

Thanks to the following, as this is where I got the info from of how to do this: https://stackoverflow.com/a/20942857

The Functional Approach

All the cool kids are doing functional programming (hello React users) these days so I thought I would give the functional solution. In my view it's actually a lot nicer than the imperatival for and each loops that have been proposed thus far and with ES6 syntax it is quite elegant.

Update

There's now a great way of doing this called findIndex which takes a function that return true/false based on whether the array element matches (as always, check for browser compatibility though).

var index = peoples.findIndex(function(person) {
  return person.attr1 == "john"
}

With ES6 syntax you get to write this:

var index = peoples.findIndex(p => p.attr1 == "john")

The (Old) Functional Approach

TL;DR

If you're looking for index where peoples[index].attr1 == "john" use:

var index = peoples.map(function(o) { return o.attr1; }).indexOf("john");

Explanation

Step 1

Use .map() to get an array of values given a particular key:

var values = object_array.map(function(o) { return o.your_key; });

The line above takes you from here:

var peoples = [
  { "attr1": "bob", "attr2": "pizza" },
  { "attr1": "john", "attr2": "sushi" },
  { "attr1": "larry", "attr2": "hummus" }
];

To here:

var values = [ "bob", "john", "larry" ];

Step 2

Now we just use .indexOf() to find the index of the key we want (which is, of course, also the index of the object we're looking for):

var index = values.indexOf(your_value);

Solution

We combine all of the above:

var index = peoples.map(function(o) { return o.attr1; }).indexOf("john");

Or, if you prefer ES6 syntax:

var index = peoples.map((o) => o.attr1).indexOf("john");

Demo:

var peoples = [_x000D_
  { "attr1": "bob", "attr2": "pizza" },_x000D_
  { "attr1": "john", "attr2": "sushi" },_x000D_
  { "attr1": "larry", "attr2": "hummus" }_x000D_
];_x000D_
_x000D_
var index = peoples.map(function(o) { return o.attr1; }).indexOf("john");_x000D_
console.log("index of 'john': " + index);_x000D_
_x000D_
var index = peoples.map((o) => o.attr1).indexOf("larry");_x000D_
console.log("index of 'larry': " + index);_x000D_
_x000D_
var index = peoples.map(function(o) { return o.attr1; }).indexOf("fred");_x000D_
console.log("index of 'fred': " + index);_x000D_
_x000D_
var index = peoples.map((o) => o.attr2).indexOf("pizza");_x000D_
console.log("index of 'pizza' in 'attr2': " + index);

The thread will block, but the process is still alive.

In a single threaded application, this means everything is blocked while you sleep. In a multithreaded application, only the thread you explicitly 'sleep' will block and the other threads still run within the process.

According to the documentation, $lookup can join only one external collection.

What you could do is to combine userInfo and userRole in one collection, as provided example is based on relational DB schema. Mongo is noSQL database - and this require different approach for document management.

Please find below 2-step query, which combines userInfo with userRole - creating new temporary collection used in last query to display combined data. In last query there is an option to use $out and create new collection with merged data for later use.

create collections

After looking at my .gitmodules, it turned out I did have an uppercase letter where I should not have. So keep in mind, the .gitmodules directories are case sensitive

The result of a modulo division is the remainder of an integer division of the given numbers.

That means:

27 / 16 = 1, remainder 11
=> 27 mod 16 = 11

Other examples:

30 / 3 = 10, remainder 0
=> 30 mod 3 = 0

35 / 3 = 11, remainder 2
=> 35 mod 3 = 2

@dapangmao's answer works, but it doesn't give the regular spark RDD, it returns a Row object. If you want to have the regular RDD format.

Try this:

rdd = df.rdd.map(tuple)

or

rdd = df.rdd.map(list)

It's an indication that connection pooling is being used (which is a good thing).

works in rails 4.1 and support symbols without quotes {:a => 'b'}

just add this to initializers folder:

class String
  def to_hash_object
    JSON.parse(self.gsub(/:([a-zA-z]+)/,'"\\1"').gsub('=>', ': ')).symbolize_keys
  end
end

Why not try using the following:

$dateTimeString = $aDateString." ".$aTimeString;
$dueDateTime = Carbon::createFromFormat('Y-m-d H:i:s', $dateTimeString, 'Europe/London');   

Best Solution for lock and change orientation on portrait and landscape:

Watch this video on YouTube:

https://m.youtube.com/watch?v=4vRrHdBowyo

This tutorial is best and simple.

or use below code:

See this picture

// 1- in second viewcontroller we set landscapeleft and in first viewcontroller we set portrat:

// 2- if you use NavigationController, you should add extension

import UIKit

class SecondViewController: UIViewController {


    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        UIDevice.current.setValue(UIInterfaceOrientation.landscapeLeft.rawValue, forKey: "orientation")
    }

    override open var shouldAutorotate: Bool {
        return false
    }

    override open var supportedInterfaceOrientations: UIInterfaceOrientationMask {
        return .landscapeLeft
    }

    override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation {
        return .landscapeLeft
    }
    
    

    override func viewDidLoad() {
        super.viewDidLoad()
    }

//write The rest of your code in here


}

//if you use NavigationController, you should add this extension

extension UINavigationController {
    override open var supportedInterfaceOrientations: UIInterfaceOrientationMask {
        return topViewController?.supportedInterfaceOrientations ?? .allButUpsideDown
    
    }
}

Look inside the implementation of the two methods to understand them deeply:

array1.equals(array2);

/**
 * Indicates whether some other object is "equal to" this one.
 * <p>
 * The {@code equals} method implements an equivalence relation
 * on non-null object references:
 * <ul>
 * <li>It is <i>reflexive</i>: for any non-null reference value
 *     {@code x}, {@code x.equals(x)} should return
 *     {@code true}.
 * <li>It is <i>symmetric</i>: for any non-null reference values
 *     {@code x} and {@code y}, {@code x.equals(y)}
 *     should return {@code true} if and only if
 *     {@code y.equals(x)} returns {@code true}.
 * <li>It is <i>transitive</i>: for any non-null reference values
 *     {@code x}, {@code y}, and {@code z}, if
 *     {@code x.equals(y)} returns {@code true} and
 *     {@code y.equals(z)} returns {@code true}, then
 *     {@code x.equals(z)} should return {@code true}.
 * <li>It is <i>consistent</i>: for any non-null reference values
 *     {@code x} and {@code y}, multiple invocations of
 *     {@code x.equals(y)} consistently return {@code true}
 *     or consistently return {@code false}, provided no
 *     information used in {@code equals} comparisons on the
 *     objects is modified.
 * <li>For any non-null reference value {@code x},
 *     {@code x.equals(null)} should return {@code false}.
 * </ul>
 * <p>

 * ({@code x == y} has the value {@code true}).
 * <p>
 * Note that it is generally necessary to override the {@code hashCode}

try

if ! grep -q sysa /etc/passwd ; then

grep returns true if it finds the search target, and false if it doesn't.

So NOT false == true.

if evaluation in shells are designed to be very flexible, and many times doesn't require chains of commands (as you have written).

Also, looking at your code as is, your use of the $( ... ) form of cmd-substitution is to be commended, but think about what is coming out of the process. Try echo $(cat /etc/passwd | grep "sysa") to see what I mean. You can take that further by using the -c (count) option to grep and then do if ! [ $(grep -c "sysa" /etc/passwd) -eq 0 ] ; then which works but is rather old school.

BUT, you could use the newest shell features (arithmetic evaluation) like

if ! (( $(grep -c "sysa" /etc/passwd) == 0 )) ; then ...`

which also gives you the benefit of using the c-lang based comparison operators, ==,<,>,>=,<=,% and maybe a few others.

In this case, per a comment by Orwellophile, the arithmetic evaluation can be pared down even further, like

if ! (( $(grep -c "sysa" /etc/passwd) )) ; then ....

OR

if (( ! $(grep -c "sysa" /etc/passwd) )) ; then ....

Finally, there is an award called the Useless Use of Cat (UUOC). :-) Some people will jump up and down and cry gothca! I'll just say that grep can take a file name on its cmd-line, so why invoke extra processes and pipe constructions when you don't have to? ;-)

I hope this helps.

From what I learned after several days of research, Here is the Guide for ASP .Net Core MVC 2.x Custom User Authentication

In Startup.cs :

Add below lines to ConfigureServices method :

public void ConfigureServices(IServiceCollection services)
{

services.AddAuthentication(
    CookieAuthenticationDefaults.AuthenticationScheme
).AddCookie(CookieAuthenticationDefaults.AuthenticationScheme,
    options =>
    {
        options.LoginPath = "/Account/Login";
        options.LogoutPath = "/Account/Logout";
    });

    services.AddMvc();

    // authentication 
    services.AddAuthentication(options =>
    {
       options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    });

    services.AddTransient(
        m => new UserManager(
            Configuration
                .GetValue<string>(
                    DEFAULT_CONNECTIONSTRING //this is a string constant
                )
            )
        );
     services.AddDistributedMemoryCache();
}

keep in mind that in above code we said that if any unauthenticated user requests an action which is annotated with [Authorize] , they well force redirect to /Account/Login url.

Add below lines to Configure method :

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
        app.UseBrowserLink();
        app.UseDatabaseErrorPage();
    }
    else
    {
        app.UseExceptionHandler(ERROR_URL);
    }
     app.UseStaticFiles();
     app.UseAuthentication();
     app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: DEFAULT_ROUTING);
    });
}

Create your UserManager class that will also manage login and logout. it should look like below snippet (note that i'm using dapper):

public class UserManager
{
    string _connectionString;

    public UserManager(string connectionString)
    {
        _connectionString = connectionString;
    }

    public async void SignIn(HttpContext httpContext, UserDbModel user, bool isPersistent = false)
    {
        using (var con = new SqlConnection(_connectionString))
        {
            var queryString = "sp_user_login";
            var dbUserData = con.Query<UserDbModel>(
                queryString,
                new
                {
                    UserEmail = user.UserEmail,
                    UserPassword = user.UserPassword,
                    UserCellphone = user.UserCellphone
                },
                commandType: CommandType.StoredProcedure
            ).FirstOrDefault();

            ClaimsIdentity identity = new ClaimsIdentity(this.GetUserClaims(dbUserData), CookieAuthenticationDefaults.AuthenticationScheme);
            ClaimsPrincipal principal = new ClaimsPrincipal(identity);

            await httpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, principal);
        }
    }

    public async void SignOut(HttpContext httpContext)
    {
        await httpContext.SignOutAsync();
    }

    private IEnumerable<Claim> GetUserClaims(UserDbModel user)
    {
        List<Claim> claims = new List<Claim>();

        claims.Add(new Claim(ClaimTypes.NameIdentifier, user.Id().ToString()));
        claims.Add(new Claim(ClaimTypes.Name, user.UserFirstName));
        claims.Add(new Claim(ClaimTypes.Email, user.UserEmail));
        claims.AddRange(this.GetUserRoleClaims(user));
        return claims;
    }

    private IEnumerable<Claim> GetUserRoleClaims(UserDbModel user)
    {
        List<Claim> claims = new List<Claim>();

        claims.Add(new Claim(ClaimTypes.NameIdentifier, user.Id().ToString()));
        claims.Add(new Claim(ClaimTypes.Role, user.UserPermissionType.ToString()));
        return claims;
    }
}

Then maybe you have an AccountController which has a Login Action that should look like below :

public class AccountController : Controller
{
    UserManager _userManager;

    public AccountController(UserManager userManager)
    {
        _userManager = userManager;
    }

    [HttpPost]
    public IActionResult LogIn(LogInViewModel form)
    {
        if (!ModelState.IsValid)
            return View(form);
         try
        {
            //authenticate
            var user = new UserDbModel()
            {
                UserEmail = form.Email,
                UserCellphone = form.Cellphone,
                UserPassword = form.Password
            };
            _userManager.SignIn(this.HttpContext, user);
             return RedirectToAction("Search", "Home", null);
         }
         catch (Exception ex)
         {
            ModelState.AddModelError("summary", ex.Message);
            return View(form);
         }
    }
}

Now you are able to use [Authorize] annotation on any Action or Controller.

Feel free to comment any questions or bug's.

After opening up an issue with the SciPy team, we found that you need to upgrade pip with:

pip install --upgrade pip

And in Python 3 this works:

python3 -m pip install --upgrade pip

for SciPy to install properly. Why? Because:

Older versions of pip have to be told to use wheels, IIRC with --use-wheel. Or you can upgrade pip itself, then it should pick up the wheels.

Upgrading pip solves the issue, but you might be able to just use the --use-wheel flag as well.

If you use Laravel, then you can use logging functions such as info() to log to the Laravel log file under storage/logs. So it won't appear in your terminal but in the log file.

extract($_POST);
$error=array();
$extension=array("jpeg","jpg","png","gif");
foreach($_FILES["files"]["tmp_name"] as $key=>$tmp_name) {
    $file_name=$_FILES["files"]["name"][$key];
    $file_tmp=$_FILES["files"]["tmp_name"][$key];
    $ext=pathinfo($file_name,PATHINFO_EXTENSION);

    if(in_array($ext,$extension)) {
        if(!file_exists("photo_gallery/".$txtGalleryName."/".$file_name)) {
            move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$file_name);
        }
        else {
            $filename=basename($file_name,$ext);
            $newFileName=$filename.time().".".$ext;
            move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$newFileName);
        }
    }
    else {
        array_push($error,"$file_name, ");
    }
}

and you must check your HTML code

<form action="create_photo_gallery.php" method="post" enctype="multipart/form-data">
    <table width="100%">
        <tr>
            <td>Select Photo (one or multiple):</td>
            <td><input type="file" name="files[]" multiple/></td>
        </tr>
        <tr>
            <td colspan="2" align="center">Note: Supported image format: .jpeg, .jpg, .png, .gif</td>
        </tr>
        <tr>
            <td colspan="2" align="center"><input type="submit" value="Create Gallery" id="selectedButton"/></td>
        </tr>
    </table>
</form>

    String encodedEncrypted = new String(encoded);

    //we recreate the same salt/encrypt as if its a separate system
    String passDecrypt = "my password";
    byte[] saltDecrypt = "choose a better salt".getBytes();

    SecretKeyFactory factoryKeyDecrypt = SecretKeyFactory

    Cipher aesCipherDecrypt = Cipher.getInstance("AES/ECB/PKCS5Padding");
            aesCipherDecrypt.init(Cipher.DECRYPT_MODE, decryptKey);

    //basically we reverse the process we did earlier

    // get the bytes from encodedEncrypted string
    byte[] e64bytes = StringUtils.getBytesUtf8(encodedEncrypted);

    // decode 64, now the bytes should be encrypted
    byte[] eBytes = Base64.decodeBase64(e64bytes);

Custom filter is more appropriate, then you can use it anywhere in the project

js file

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

myApp.filter('utcdate', ['$filter','$locale', function($filter, $locale){

    return function (input, format) {
        if (!angular.isDefined(format)) {
            format = $locale['DATETIME_FORMATS']['medium'];
        }

        var date = new Date(input);
        var d = new Date()
        var _utc = new Date(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(),  date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds());
        return $filter('date')(_utc, format)
    };

 }]);

in template

<p>This will convert UTC time to local time<p>
<span>{{dateTimeInUTC | utcdate :'MMM d, y h:mm:ss a'}}</span>
