MSDTC must be enabled on both systems, both server and client.
Also, make sure that there isn't a firewall between the systems that blocks RPC.
DTCTest is a nice litt app that helps you to troubleshoot any other problems.

You Can use simply git checkout <commit hash>

in this sequence

bash git clone [URLTORepository] git checkout [commithash]

commit hash looks like this "45ef55ac20ce2389c9180658fdba35f4a663d204"

I doubt css understands left by itself. You need to use it specifying position. You are using .css() correctly

position: relative/absolute/whatever;
left: 900px;

heres a fiddle of it working

http://jsfiddle.net/gFLZe/

and without the position here's what you get

http://jsfiddle.net/gkkm5/

Change your if statement to be like this - with quotes around -900px

var n = $("items").css("left");

if(n == '-900px'){
    $(".items span").fadeOut("slow");
}

One thing __init__.py allows is converting a module to a package without breaking the API or creating extraneous nested namespaces or private modules*. This helps when I want to extend a namespace.

If I have a file util.py containing

def foo():
    ...

then users will access foo with

from util import foo

If I then want to add utility functions for database interaction, and I want them to have their own namespace under util, I'll need a new directory**, and to keep API compatibility (so that from util import foo still works), I'll call it util/. I could move util.py into util/ like so,

util/
  __init__.py
  util.py
  db.py

and in util/__init__.py do

from util import *

but this is redundant. Instead of having a util/util.py file, we can just put the util.py contents in __init__.py and the user can now

from util import foo
from util.db import check_schema

I think this nicely highlights how a util package's __init__.py acts in a similar way to a util module

* this is hinted at in the other answers, but I want to highlight it here
** short of employing import gymnastics. Note it won't work to create a new package with the same name as the file, see this

The simplest in my opinion is just this:

it = iter([1,2,3,4,5,6])
for x, y in zip(it, it):
    print x, y

Out: 1 2
     3 4
     5 6

No extra imports or anything. And very elegant, in my opinion.

If you can live with a fixed aspect ratio and you would like a responsive iframe, this code will be useful to you. It's just CSS rules.

.iframe-container {
  overflow: hidden;
  /* Calculated from the aspect ration of the content (in case of 16:9 it is 9/16= 
  0.5625) */
  padding-top: 56.25%;
  position: relative;
}
.iframe-container iframe {
  border: 0;
  height: 100%;
  left: 0;
  position: absolute;
  top: 0;
  width: 100%;
}

The iframe must have a div as container.

<div class="iframe-container">
   <iframe src="http://example.org"></iframe>
</div>

The source code is based on this site and Ben Marshall has a good explanation.

Both are shorthands for longer expressions.

?: is short for $a ? $a : $b. This expression will evaluate to $a if $a evaluates to TRUE.

?? is short for isset($a) ? $a : $b. This expression will evaluate to $a if $a is set and not null.

Their use cases overlaps when $a is undefined or null. When $a is undefined ?? will not produce an E_NOTICE, but the results are the same. When $a is null the result is the same.

I'm having a very similar problem. In the past, this has been related to serialization problems. If you are still having this problem, can you verify that you can correctly serialize the objects you are returning. Specifically, if you are using Linq-To-Sql objects that have relationships, there are known serialization problems if you put a back reference on a child object to the parent object and mark that back reference as a DataMember.

You can verify serialization by writing a console app that serializes and deserializes your objects using the DataContractSerializer on the server side and whatever serialization methods your client uses. For example, in our current application, we have both WPF and Compact Framework clients. I wrote a console app to verify that I can serialize using a DataContractSerializer and deserialize using an XmlDesserializer. You might try that.

Also, if you are returning Linq-To-Sql objects that have child collections, you might try to ensure that you have eagerly loaded them on the server side. Sometimes, because of lazy loading, the objects being returned are not populated and may cause the behavior you are seeing where the request is sent to the service method multiple times.

If you have solved this problem, I'd love to hear how because I'm stuck with it too. I have verified that my issue is not serialization so I'm at a loss.

UPDATE: I'm not sure if it will help you any but the Service Trace Viewer Tool just solved my problem after 5 days of very similar experience to yours. By setting up tracing and then looking at the raw XML, I found the exceptions that were causing my serialization problems. It was related to Linq-to-SQL objects that occasionally had more child objects than could be successfully serialized. Adding the following to your web.config file should enable tracing:

<sharedListeners>
    <add name="sharedListener"
         type="System.Diagnostics.XmlWriterTraceListener"
         initializeData="c:\Temp\servicetrace.svclog" />
  </sharedListeners>
  <sources>
    <source name="System.ServiceModel" switchValue="Verbose, ActivityTracing" >
      <listeners>
        <add name="sharedListener" />
      </listeners>
    </source>
    <source name="System.ServiceModel.MessageLogging" switchValue="Verbose">
      <listeners>
        <add name="sharedListener" />
      </listeners>
    </source>
  </sources>

The resulting file can be opened with the Service Trace Viewer Tool or just in IE to examine the results.

Use dot notation and/or bracket notation to access object properties and for loops to iterate arrays:

var d, i;

for (i = 0; i < dictionary.data.length; i++) {
  d = dictionary.data[i];
  alert(d.id + ' ' + d.name);
}

You can also iterate arrays using for..in loops; however, properties added to Array.prototype may show through, and you may not necessarily get array elements in their correct order, or even in any consistent order.

In XAML, add and define a RowStyle Property for the DataGrid with a goal to set the Background of the Row, to the Color defined in my Employee Object.

<DataGrid AutoGenerateColumns="False" ItemsSource="EmployeeList">
   <DataGrid.RowStyle>
        <Style TargetType="DataGridRow">
             <Setter Property="Background" Value="{Binding ColorSet}"/>
        </Style>
   </DataGrid.RowStyle>

And in my Employee Class

public class Employee {

    public int Id { get; set; }
    public string Name { get; set; }
    public int Age { get; set; }

    public string ColorSet { get; set; }

    public Employee() { }

    public Employee(int id, string name, int age)
    {
        Id = id;
        Name = name;
        Age = age;
        if (Age > 50)
        {
            ColorSet = "Green";
        }
        else if (Age > 100)
        {
            ColorSet = "Red";
        }
        else
        {
            ColorSet = "White";
        }
    }
}

This way every Row of the DataGrid has the BackGround Color of the ColorSet Property of my Object.

Simply create an object of Base64 and use it to encode or decode, when using org.apache.commons.codec.binary.Base64 library

To Encode

Base64 ed=new Base64();

String encoded=new String(ed.encode("Hello".getBytes()));

Replace "Hello" with the text to be encoded in String Format.

To Decode

Base64 ed=new Base64();

String decoded=new String(ed.decode(encoded.getBytes()));

Here encoded is the String variable to be decoded

A layer in a neural network without a bias is nothing more than the multiplication of an input vector with a matrix. (The output vector might be passed through a sigmoid function for normalisation and for use in multi-layered ANN afterwards but that’s not important.)

This means that you’re using a linear function and thus an input of all zeros will always be mapped to an output of all zeros. This might be a reasonable solution for some systems but in general it is too restrictive.

Using a bias, you’re effectively adding another dimension to your input space, which always takes the value one, so you’re avoiding an input vector of all zeros. You don’t lose any generality by this because your trained weight matrix needs not be surjective, so it still can map to all values previously possible.

2d ANN:

For a ANN mapping two dimensions to one dimension, as in reproducing the AND or the OR (or XOR) functions, you can think of a neuronal network as doing the following:

On the 2d plane mark all positions of input vectors. So, for boolean values, you’d want to mark (-1,-1), (1,1), (-1,1), (1,-1). What your ANN now does is drawing a straight line on the 2d plane, separating the positive output from the negative output values.

Without bias, this straight line has to go through zero, whereas with bias, you’re free to put it anywhere. So, you’ll see that without bias you’re facing a problem with the AND function, since you can’t put both (1,-1) and (-1,1) to the negative side. (They are not allowed to be on the line.) The problem is equal for the OR function. With a bias, however, it’s easy to draw the line.

Note that the XOR function in that situation can’t be solved even with bias.

Here goes my humble attempt to explain the concept to newbies around the world: (a color coded version on my blog too)

A lot of people run to a lone phone booth (they don't have mobile phones) to talk to their loved ones. The first person to catch the door-handle of the booth, is the one who is allowed to use the phone. He has to keep holding on to the handle of the door as long as he uses the phone, otherwise someone else will catch hold of the handle, throw him out and talk to his wife :) There's no queue system as such. When the person finishes his call, comes out of the booth and leaves the door handle, the next person to get hold of the door handle will be allowed to use the phone.

A thread is : Each person
The mutex is : The door handle
The lock is : The person's hand
The resource is : The phone

Any thread which has to execute some lines of code which should not be modified by other threads at the same time (using the phone to talk to his wife), has to first acquire a lock on a mutex (clutching the door handle of the booth). Only then will a thread be able to run those lines of code (making the phone call).

Once the thread has executed that code, it should release the lock on the mutex so that another thread can acquire a lock on the mutex (other people being able to access the phone booth).

[The concept of having a mutex is a bit absurd when considering real-world exclusive access, but in the programming world I guess there was no other way to let the other threads 'see' that a thread was already executing some lines of code. There are concepts of recursive mutexes etc, but this example was only meant to show you the basic concept. Hope the example gives you a clear picture of the concept.]

With C++11 threading:

#include <iostream>
#include <thread>
#include <mutex>

std::mutex m;//you can use std::lock_guard if you want to be exception safe
int i = 0;

void makeACallFromPhoneBooth() 
{
    m.lock();//man gets a hold of the phone booth door and locks it. The other men wait outside
      //man happily talks to his wife from now....
      std::cout << i << " Hello Wife" << std::endl;
      i++;//no other thread can access variable i until m.unlock() is called
      //...until now, with no interruption from other men
    m.unlock();//man lets go of the door handle and unlocks the door
}

int main() 
{
    //This is the main crowd of people uninterested in making a phone call

    //man1 leaves the crowd to go to the phone booth
    std::thread man1(makeACallFromPhoneBooth);
    //Although man2 appears to start second, there's a good chance he might
    //reach the phone booth before man1
    std::thread man2(makeACallFromPhoneBooth);
    //And hey, man3 also joined the race to the booth
    std::thread man3(makeACallFromPhoneBooth);

    man1.join();//man1 finished his phone call and joins the crowd
    man2.join();//man2 finished his phone call and joins the crowd
    man3.join();//man3 finished his phone call and joins the crowd
    return 0;
}

Compile and run using g++ -std=c++0x -pthread -o thread thread.cpp;./thread

Instead of explicitly using lock and unlock, you can use brackets as shown here, if you are using a scoped lock for the advantage it provides. Scoped locks have a slight performance overhead though.

Suppose you have a tree like this:

dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]

First, checkout a temp branch:

git checkout -b temp

On temp branch, reset --hard to a commit that you want to change its message (for example, that commit is 946992):

git reset --hard 946992

Use amend to change the message:

git commit --amend -m "<new_message>"

After that the tree will look like this:

dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]
           \
            b886a0 [temp]

Then, cherry-pick all the commit that is ahead of 946992 from master to temp and commit them, use amend if you want to change their messages as well:

git cherry-pick 9143a9
git commit --amend -m "<new_message>
...
git cherry-pick 5a6057
git commit --amend -m "<new_message>

The tree now looks like this:

dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master]
               \
                b886a0 - 41ab2c - 6c2a3s - 7c88c9 [temp]

Now force push the temp branch to remote:

git push --force origin temp:master

The final step, delete branch master on local, git fetch origin to pull branch master from the server, then switch to branch master and delete branch temp.

Now both your local and remote will have all the messages updated.

Just finish it up.

string sqlCommand = "SELECT * FROM TABLE";
string connectionString = "blahblah";

DataSet ds = GetDataSet(sqlCommand, connectionString);

DataSet GetDataSet(string sqlCommand, string connectionString)
{
    DataSet ds = new DataSet();
    using (SqlCommand cmd = new SqlCommand(
        sqlCommand, new SqlConnection(connectionString)))
    {
        cmd.Connection.Open();
        DataTable table = new DataTable();
        table.Load(cmd.ExecuteReader());
        ds.Tables.Add(table);
    }
    return ds;
}

No such thing, sorry.

Though the spec states:

A future version of the 2D context API may provide a way to render fragments of documents, rendered using CSS, straight to the canvas.

Which may be as close as you'll get.

A lot of people want a ctx.drawArbitraryHTML/Element kind of deal but there's nothing built in like that.

The only exception is Mozilla's exclusive drawWindow, which draws a snapshot of the contents of a DOM window into the canvas. This feature is only available for code running with Chrome ("local only") privileges. It is not allowed in normal HTML pages. So you can use it for writing FireFox extensions like this one does but that's it.

I am using Windows 8.1 environment. I had the same problem while running my first java program after installing Eclipse recently. I had installed java on d drive at d:\java. But Eclipse was looking at the default installation c:\programfiles\java. I did the following:

1. Modified my eclipse.ini file and added the following after open:

   -vm
   d:\java\jdk1.8.0_161\bin 
   

2. While creating the java program I have to unselect default build path and then select d:\java.

After this, the program ran well and got the hello world to work.

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

And for home page add only '/'

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

Had a similar problem, fixed it by calling python3 instead of python, my modules were in Python3.5.

Probably the best way to learn how to structure your program is by reading other people's code, especially if it's a large program to which many people have contributed. After looking at the code of many projects, you should get an idea of what the consensus style should be.

Python, as a language, is special in that there are some strong guidelines as to how you should format your code. The first is the so-called "Zen of Python":

• Beautiful is better than ugly.
• Explicit is better than implicit.
• Simple is better than complex.
• Complex is better than complicated.
• Flat is better than nested.
• Sparse is better than dense.
• Readability counts.
• Special cases aren't special enough to break the rules.
• Although practicality beats purity.
• Errors should never pass silently.
• Unless explicitly silenced.
• In the face of ambiguity, refuse the temptation to guess.
• There should be one-- and preferably only one --obvious way to do it.
• Although that way may not be obvious at first unless you're Dutch.
• Now is better than never.
• Although never is often better than right now.
• If the implementation is hard to explain, it's a bad idea.
• If the implementation is easy to explain, it may be a good idea.
• Namespaces are one honking great idea -- let's do more of those!

On a more practical level, there is PEP8, the style guide for Python.

With those in mind, I would say that your code style doesn't really fit, particularly the nested functions. Find a way to flatten those out, either by using classes or moving them into separate modules. This will make the structure of your program much easier to understand.

As of early 2013, the ICU project, maintained by IBM, is a pretty good answer to this.

http://site.icu-project.org/

ICU is a "complete, portable Unicode library that closely tracks industry standards." For the specific problem of string comparison, the Collation object does what you want.

The Mozilla Project adopted ICU for internationalization in Firefox in mid-2012; you can track the engineering discussion, including issues of build systems and data file size, here:

Just put one more entry in your spring xml file i.e.mvc-dispatcher-servlet.xml

<mvc:view-controller path="/" view-name="index"/>

After putting this to your xml put your default view or jsp file in your custom JSP folder as you have mentioned in mvc-dispatcher-servlet.xml file.

change index with your jsp name.

You're missing a closing parenthesis ) in print():

print('{0}+{1}={2}'.format(n1,n2,t1))

and you're also not storing the returned value from int(), so z is still a string.

z = input('?')
z = int(z)

or simply:

z = int(input('?'))

This is due the contract of Float.toString(float), which says in part:

How many digits must be printed for the fractional part […]? There must be at least one digit to represent the fractional part, and beyond that as many, but only as many, more digits as are needed to uniquely distinguish the argument value from adjacent values of type float. That is, suppose that x is the exact mathematical value represented by the decimal representation produced by this method for a finite nonzero argument f. Then f must be the float value nearest to x; or, if two float values are equally close to x, then f must be one of them and the least significant bit of the significand of f must be 0.

you need to use YYYY-MM-DD format to insert date in mysql

While the answers above are good they will not catch network errors. As Mark mentioned, BadResponseException is just a super class for ClientException and ServerException. But RequestException is also a super class of BadResponseException. RequestException will be thrown for not only 400 and 500 errors but network errors and infinite redirects too. So let's say you request the page below but your network is playing up and your catch is only expecting a BadResponseException. Well your application will throw an error.

It's better in this case to expect RequestException and check for a response.

try {
  $client->get('http://123123123.com')
} catch (RequestException $e) {

  // If there are network errors, we need to ensure the application doesn't crash.
  // if $e->hasResponse is not null we can attempt to get the message
  // Otherwise, we'll just pass a network unavailable message.
  if ($e->hasResponse()) {
    $exception = (string) $e->getResponse()->getBody();
    $exception = json_decode($exception);
    return new JsonResponse($exception, $e->getCode());
  } else {
    return new JsonResponse($e->getMessage(), 503);
  }

}

Have a look at the functions strcmp and strncmp.

A PHP array or object or other complex data structure cannot be transported or stored or otherwise used outside of a running PHP script. If you want to persist such a complex data structure beyond a single run of a script, you need to serialize it. That just means to put the structure into a "lower common denominator" that can be handled by things other than PHP, like databases, text files, sockets. The standard PHP function serialize is just a format to express such a thing, it serializes a data structure into a string representation that's unique to PHP and can be reversed into a PHP object using unserialize. There are many other formats though, like JSON or XML.

Take for example this common problem:

How do I pass a PHP array to Javascript?

PHP and Javascript can only communicate via strings. You can pass the string "foo" very easily to Javascript. You can pass the number 1 very easily to Javascript. You can pass the boolean values true and false easily to Javascript. But how do you pass this array to Javascript?

Array ( [1] => elem 1 [2] => elem 2 [3] => elem 3 ) 

The answer is serialization. In case of PHP/Javascript, JSON is actually the better serialization format:

{ 1 : 'elem 1', 2 : 'elem 2', 3 : 'elem 3' }

Javascript can easily reverse this into an actual Javascript array.

This is just as valid a representation of the same data structure though:

a:3:{i:1;s:6:"elem 1";i:2;s:6:"elem 2";i:3;s:7:" elem 3";}

But pretty much only PHP uses it, there's little support for this format anywhere else.
This is very common and well supported as well though:

<array>
    <element key='1'>elem 1</element>
    <element key='2'>elem 2</element>
    <element key='3'>elem 3</element>
</array>

There are many situations where you need to pass complex data structures around as strings. Serialization, representing arbitrary data structures as strings, solves how to do this.

Found the solution as below.... posting it as it could help somebody else too :)

DateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
Date date = format.parse("2014-04-24 11:15:00");

GregorianCalendar cal = new GregorianCalendar();
cal.setTime(date);

XMLGregorianCalendar xmlGregCal =  DatatypeFactory.newInstance().newXMLGregorianCalendar(cal);

System.out.println(xmlGregCal);

Output:

2014-04-24T11:15:00.000+02:00

There is no "one-to-one" mapping between XML and JSON, so converting one to the other necessarily requires some understanding of what you want to do with the results.

That being said, Python's standard library has several modules for parsing XML (including DOM, SAX, and ElementTree). As of Python 2.6, support for converting Python data structures to and from JSON is included in the json module.

So the infrastructure is there.

You have a syntax error Please try the following syntax as given below:

string StrQuery="INSERT INTO tableName VALUES ('" + dataGridView1.Rows[i].Cells[0].Value + "',' " + dataGridView1.Rows[i].Cells[1].Value + "', '" + dataGridView1.Rows[i].Cells[2].Value + "', '" + dataGridView1.Rows[i].Cells[3].Value + "',' " + dataGridView1.Rows[i].Cells[4].Value + "')";

If you guys still interested, here is my workaround based on Guzzle middleware feature:

1. Create JsonAwaraResponse that will decode JSON response by Content-Type HTTP header, if not - it will act as standard Guzzle Response:

   <?php
   
   namespace GuzzleHttp\Psr7;
   
   
   class JsonAwareResponse extends Response
   {
       /**
        * Cache for performance
        * @var array
        */
       private $json;
   
       public function getBody()
       {
           if ($this->json) {
               return $this->json;
           }
           // get parent Body stream
           $body = parent::getBody();
   
           // if JSON HTTP header detected - then decode
           if (false !== strpos($this->getHeaderLine('Content-Type'), 'application/json')) {
               return $this->json = \json_decode($body, true);
           }
           return $body;
       }
   }
   

2. Create Middleware which going to replace Guzzle PSR-7 responses with above Response implementation:

   <?php
   
   $client = new \GuzzleHttp\Client();
   
   /** @var HandlerStack $handler */
   $handler = $client->getConfig('handler');
   $handler->push(\GuzzleHttp\Middleware::mapResponse(function (\Psr\Http\Message\ResponseInterface $response) {
       return new \GuzzleHttp\Psr7\JsonAwareResponse(
           $response->getStatusCode(),
           $response->getHeaders(),
           $response->getBody(),
           $response->getProtocolVersion(),
           $response->getReasonPhrase()
       );
   }), 'json_decode_middleware');
   

After this to retrieve JSON as PHP native array use Guzzle as always:

$jsonArray = $client->get('http://httpbin.org/headers')->getBody();

Tested with guzzlehttp/guzzle 6.3.3

See following snippet :

$(document).on("click", "a.deleteText", function() {_x000D_
    if (confirm('Are you sure ?')) {_x000D_
        $(this).prev('span.text').remove();_x000D_
    }_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_

</div>

Use grep or grepl but be aware of whether or not you want to use regular expressions.

By default, grep and related take a regular expression to match, not a literal substring. If you're not expecting that, and you try to match on an invalid regex, it doesn't work:

> grep("[", "abc[")
Error in grep("[", "abc[") : 
  invalid regular expression '[', reason 'Missing ']''

To do a true substring test, use fixed = TRUE.

> grep("[", "abc[", fixed = TRUE)
[1] 1

If you do want regex, great, but that's not what the OP appears to be asking.

A lot of overly-complicated answers here, perhaps because this is not easy to find in the iOS documentation. JosephH had it right above:

[[view window] endEditing:YES];

This is work perfect for me if you don't allow sorting the first column then use

<script>
    $(document).ready(function () {
        $('#example2').DataTable({               
            'order':[],
            'columnDefs': [{
                "targets": 0,
                "orderable": false
            }]
        });
    });
</script>

here index row starts with 0, so put 0 in targets.
And if you disable sorting for one or more column then use,

<script>
    $(document).ready(function () {
        $('#example2').DataTable({               
            'order':[],
            'columnDefs': [{
                "targets": [0,3],
                "orderable": false
            }]
        });
    });
</script>

Here you can see ,

Above my checkbox column at 0 positions and Action column at 3rd position so sorting disable in both table.

Default constructors -- public constructors with out arguments (either declared or implied) -- are inherited by default. You can try the following code for an example of this:

public class CtorTest {
    public static void main(String[] args) {
        final Sub sub = new Sub();
        System.err.println("Finished.");
    }

    private static class Base {
        public Base() {
            System.err.println("In Base ctor");
        }
    }

    private static class Sub extends Base {
        public Sub() {
            System.err.println("In Sub ctor");
        }
    }
}

If you want to explicitly call a constructor from a super class, you need to do something like this:

public class Ctor2Test {
    public static void main(String[] args) {
        final Sub sub = new Sub();
        System.err.println("Finished.");
    }

    private static class Base {
        public Base() {
            System.err.println("In Base ctor");
        }

        public Base(final String toPrint) {
            System.err.println("In Base ctor.  To Print: " + toPrint);
        }
    }

    private static class Sub extends Base {
        public Sub() {
            super("Hello World!");
            System.err.println("In Sub ctor");
        }
    }
}

The only caveat is that the super() call must come as the first line of your constructor, else the compiler will get mad at you.

My approach was as follows (in PHP):

$url = "whatever_you_need"

$html = file_get_contents('https://en.wikipedia.org/w/api.php?action=opensearch&search='.$url);
$utf8html = html_entity_decode(preg_replace("/U\+([0-9A-F]{4})/", "&#x\\1;", $html), ENT_NOQUOTES, 'UTF-8');

$utf8html might need further cleaning, but that's basically it.

There is a Swift 3 solution from the checked solution :

self.perform(#selector(self.targetMethod), with: self, afterDelay: 1.0)

And there is the method

@objc fileprivate func targetMethod(){

}

The top answer is equivalent to doing:

let text = find.reduce((acc, item, i) => {
  const regex = new RegExp(item, "g");
  return acc.replace(regex, replace[i]);
}, textarea);

Given this:

var textarea = $(this).val();
var find = ["<", ">", "\n"];
var replace = ["&lt;", "&gt;", "<br/>"];

In this case, no imperative programming is going on.

I just had the same problem. It is not a network permission but rather thread issue. Below code helped me to solve it. Put is in main activity

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    if (android.os.Build.VERSION.SDK_INT > 9)
    {
        StrictMode.ThreadPolicy policy = new 
        StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
    }

Another easy way to insert your own icon on the title bar in JavaFX is to add the image to your primary stage using the following method:

Image ico = new Image("resources/images/iconLogo.png");
stage.getIcons().add(ico);

Make sure your import javafx.scene.image.Image (if using an ide like netbeans this should be automatically done for you).

While that particular idiom is common, even more common is for people to use = when they mean ==. The convention when you really mean the = is to use an extra layer of parentheses:

while ((list = list->next)) { // yes, it's an assignment

You can tell whether Apache is using preform or worker by issuing the following command

apache2ctl -l

In the resulting output, look for mentions of prefork.c or worker.c

You can use C style string formatting:

"%d:%d:d" % (hours, minutes, seconds)

See here, especially: https://web.archive.org/web/20120415173443/http://diveintopython3.ep.io/strings.html

you can use script module

Example

- name: Transfer and execute a script.
  hosts: all
  tasks:

     - name: Copy and Execute the script 
       script: /home/user/userScript.sh

TL;DR : Use StratifiedShuffleSplit with test_size=0.25

Scikit-learn provides two modules for Stratified Splitting:

1. StratifiedKFold : This module is useful as a direct k-fold cross-validation operator: as in it will set up n_folds training/testing sets such that classes are equally balanced in both.

Heres some code(directly from above documentation)

>>> skf = cross_validation.StratifiedKFold(y, n_folds=2) #2-fold cross validation
>>> len(skf)
2
>>> for train_index, test_index in skf:
...    print("TRAIN:", train_index, "TEST:", test_index)
...    X_train, X_test = X[train_index], X[test_index]
...    y_train, y_test = y[train_index], y[test_index]
...    #fit and predict with X_train/test. Use accuracy metrics to check validation performance

2. StratifiedShuffleSplit : This module creates a single training/testing set having equally balanced(stratified) classes. Essentially this is what you want with the n_iter=1. You can mention the test-size here same as in train_test_split

Code:

>>> sss = StratifiedShuffleSplit(y, n_iter=1, test_size=0.5, random_state=0)
>>> len(sss)
1
>>> for train_index, test_index in sss:
...    print("TRAIN:", train_index, "TEST:", test_index)
...    X_train, X_test = X[train_index], X[test_index]
...    y_train, y_test = y[train_index], y[test_index]
>>> # fit and predict with your classifier using the above X/y train/test

If I recall correctly Twig doesn't support || and && operators, but requires or and and to be used respectively. I'd also use parentheses to denote the two statements more clearly although this isn't technically a requirement.

{%if ( fields | length > 0 ) or ( trans_fields | length > 0 ) %}

Expressions

Expressions can be used in {% blocks %} and ${ expressions }.

Operator    Description
==          Does the left expression equal the right expression?
+           Convert both arguments into a number and add them.
-           Convert both arguments into a number and substract them.
*           Convert both arguments into a number and multiply them.
/           Convert both arguments into a number and divide them.
%           Convert both arguments into a number and calculate the rest of the integer division.
~           Convert both arguments into a string and concatenate them.
or          True if the left or the right expression is true.
and         True if the left and the right expression is true.
not         Negate the expression.

For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:

{% if (foo and bar) or (fizz and (foo + bar == 3)) %}

In addition to Tim's answer, which is very appropriate to your specific example, it's worth mentioning collections.defaultdict, which lets you do stuff like this:

>>> d = defaultdict(int)
>>> d[0] += 1
>>> d
{0: 1}
>>> d[4] += 1
>>> d
{0: 1, 4: 1}

For mapping [1, 2, 3, 4] as in your example, it's a fish out of water. But depending on the reason you asked the question, this may end up being a more appropriate technique.

 1. Create the database

CREATE DATABASE db_name;

 2. Create the username for the database db_name

GRANT ALL PRIVILEGES ON db_name.* TO 'username'@'localhost' IDENTIFIED BY 'password';

 3. Use the database

USE db_name;

 4. Finally you are in database db_name and then execute the commands like create , select and insert operations.

There are so many ways:

1. NSURL

2. ASIHTTP

3. libcurl

4. easyget, a commercial one with powerful features.

Using column name worked for me.

sorted_df = df.sort_values(by=['Column_name'], ascending=True)

A rather simple solution is to create a singleton manager class, in which you can store a reference to one or more Activities, or anything else you want access to throughout the app.

Call UberManager.getInstance().setMainActivity( activity ); in the main activity's onCreate.

Call UberManager.getInstance().getMainActivity(); anywhere in your app to retrieve it. (I am using this to be able to use Toast from a non UI thread.)

Make sure you add a call to UberManager.getInstance().cleanup(); when your app is being destroyed.

import android.app.Activity;

public class UberManager
{
    private static UberManager instance = new UberManager();

    private Activity mainActivity = null;

    private UberManager()
    {

    }

    public static UberManager getInstance()
    {
        return instance;
    }

    public void setMainActivity( Activity mainActivity )
    {
        this.mainActivity = mainActivity;
    }

    public Activity getMainActivity()
    {
        return mainActivity;
    }

    public void cleanup()
    {
        mainActivity = null;
    }
}

You'll get this error as well if you are verifying that an extension method of an interface is called.

For example if you are mocking:

var mockValidator = new Mock<IValidator<Foo>>();
mockValidator
  .Verify(validator => validator.ValidateAndThrow(foo, null));

You will get the same exception because .ValidateAndThrow() is an extension on the IValidator<T> interface.

public static void ValidateAndThrow<T>(this IValidator<T> validator, T instance, string ruleSet = null)...

len = max(key for (item, key) in list)
newlist = [[] for i in range(len+1)]
for item,key in list:
  newlist[key].append(item)

You can do it in a single list comprehension, perhaps more elegant but O(n**2):

[[item for (item,key) in list if key==i] for i in range(max(key for (item,key) in list)+1)]

I open the project,.csproj, using a notepad and delete that missing file reference.

Unfortunately, np.polynomial.polynomial.polyfit returns the coefficients in the opposite order of that for np.polyfit and np.polyval (or, as you used np.poly1d). To illustrate:

In [40]: np.polynomial.polynomial.polyfit(x, y, 4)
Out[40]: 
array([  84.29340848, -100.53595376,   44.83281408,   -8.85931101,
          0.65459882])

In [41]: np.polyfit(x, y, 4)
Out[41]: 
array([   0.65459882,   -8.859311  ,   44.83281407, -100.53595375,
         84.29340846])

In general: np.polynomial.polynomial.polyfit returns coefficients [A, B, C] to A + Bx + Cx^2 + ..., while np.polyfit returns: ... + Ax^2 + Bx + C.

So if you want to use this combination of functions, you must reverse the order of coefficients, as in:

ffit = np.polyval(coefs[::-1], x_new)

However, the documentation states clearly to avoid np.polyfit, np.polyval, and np.poly1d, and instead to use only the new(er) package.

You're safest to use only the polynomial package:

import numpy.polynomial.polynomial as poly

coefs = poly.polyfit(x, y, 4)
ffit = poly.polyval(x_new, coefs)
plt.plot(x_new, ffit)

Or, to create the polynomial function:

ffit = poly.Polynomial(coefs)    # instead of np.poly1d
plt.plot(x_new, ffit(x_new))

For swift programming

func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
  if editingStyle == UITableViewCellEditingStyle.Delete {
    deleteModelAt(indexPath.row)
    self.tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Automatic)
  }
  else if editingStyle == UITableViewCellEditingStyle.Insert {
    println("insert editing action")
  }
}

func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [AnyObject]? {
  var archiveAction = UITableViewRowAction(style: .Default, title: "Archive",handler: { (action: UITableViewRowAction!, indexPath: NSIndexPath!) in
        // maybe show an action sheet with more options
        self.tableView.setEditing(false, animated: false)
      }
  )
  archiveAction.backgroundColor = UIColor.lightGrayColor()

  var deleteAction = UITableViewRowAction(style: .Normal, title: "Delete",
      handler: { (action: UITableViewRowAction!, indexPath: NSIndexPath!) in
        self.deleteModelAt(indexPath.row)
        self.tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Automatic);
      }
  );
  deleteAction.backgroundColor = UIColor.redColor()

  return [deleteAction, archiveAction]
}

func deleteModelAt(index: Int) {
  //... delete logic for model
}

When we convert PHP array into JS array then we get all values in string. For example:

var ars= '<?php echo json_encode($abc); ?>';

The issue in above method is when we try to get the first element of ars[0] then it gives us bracket where as in we need first element as compare to bracket so the better way to this is

var packing_slip_orders = JSON.parse('<?php echo json_encode($packing_slip_orders); ?>');

You should use json_parse after json_encode to get the accurate array result.

You can subtract 7 from the current date with this:

WHERE datex BETWEEN DATEADD(day, -7, GETDATE()) AND GETDATE()

If you just want the content as string, then the simple solution is to use the ReadFile function from the io/ioutil package. This function returns a slice of bytes which you can easily convert to a string.

package main

import (
    "fmt"
    "io/ioutil"
)

func main() {
    b, err := ioutil.ReadFile("file.txt") // just pass the file name
    if err != nil {
        fmt.Print(err)
    }

    fmt.Println(b) // print the content as 'bytes'

    str := string(b) // convert content to a 'string'

    fmt.Println(str) // print the content as a 'string'
}

to validate the email string you will need to write a regular expression to check it is in the correct form. there are plenty out on the web but be carefull as some can exclude what are actually legal addresses.

essentially it will look something like this

^((?>[a-zA-Z\d!#$%&'*+\-/=?^_`{|}~]+\x20*|"((?=[\x01-\x7f])[^"\\]|\\[\x01-\x7f])*"\x20*)*(?<angle><))?((?!\.)(?>\.?[a-zA-Z\d!#$%&'*+\-/=?^_`{|}~]+)+|"((?=[\x01-\x7f])[^"\\]|\\[\x01-\x7f])*")@(((?!-)[a-zA-Z\d\-]+(?<!-)\.)+[a-zA-Z]{2,}|\[(((?(?<!\[)\.)(25[0-5]|2[0-4]\d|[01]?\d?\d)){4}|[a-zA-Z\d\-]*[a-zA-Z\d]:((?=[\x01-\x7f])[^\\\[\]]|\\[\x01-\x7f])+)\])(?(angle)>)$

Actually checking if the email exists and doesn't bounce would mean sending an email and seeing what the result was. i.e. it bounced or it didn't. However it might not bounce for several hours or not at all and still not be a "real" email address. There are a number of services out there which purport to do this for you and would probably be paid for by you and quite frankly why bother to see if it is real?

It is good to check the user has not misspelt their email else they could enter it incorrectly, not realise it and then get hacked of with you for not replying. However if someone wants to add a bum email address there would be nothing to stop them creating it on hotmail or yahoo (or many other places) to gain the same end.

So do the regular expression and validate the structure but forget about validating against a service.

I have also discovered that, when using JNI, invoking a Java method from C++, if you pass parameters to the invoked Java method in the wrong order, you will get this error when you attempt to use the parameters inside the called method (because they won't be the right type). I was initially taken aback that JNI does not do this checking for you as part of the class signature checking when you invoke the method, but I assume they don't do this kind of checking because you may be passing polymorphic parameters and they have to assume you know what you are doing.

Example C++ JNI Code:

void invokeFooDoSomething() {
    jobject javaFred = FredFactory::getFred(); // Get a Fred jobject
    jobject javaFoo = FooFactory::getFoo(); // Get a Foo jobject
    jobject javaBar = FooFactory::getBar(); // Get a Bar jobject
    jmethodID methodID = getDoSomethingMethodId() // Get the JNI Method ID


    jniEnv->CallVoidMethod(javaFoo,
                           methodID,
                           javaFred, // Woops!  I switched the Fred and Bar parameters!
                           javaBar);

    // << Insert error handling code here to discover the JNI Exception >>
    //  ... This is where the IncompatibleClassChangeError will show up.
}

Example Java Code:

class Bar { ... }

class Fred {
    public int size() { ... }
} 

class Foo {
    public void doSomething(Fred aFred, Bar anotherObject) {
        if (name.size() > 0) { // Will throw a cryptic java.lang.IncompatibleClassChangeError
            // Do some stuff...
        }
    }
}

I am using a spreadsheet with headers in row 1, data are in rows 2 and below.

IDs are in column A. To count how many different values there are I put this formula from row 2 to the end of the spreadsheet of the first available column [F in my case] : "=IF(A2=A1,F1+1,1)".

Then I use the following formula in a free cell: "=COUNTIF(F:F,1)". In this way I am sure every ID is counted.

Please note that IDs must be sorted, otherwise they will be counted more than once...but unlike array formulas it is very fast even with a 150000 rows spreadsheet.

Similar to Julien's answer above, I had success with the following:

fig, ax = plt.subplots(figsize=(10,4))
for key, grp in df.groupby(['ticker']):
    ax.plot(grp['Date'], grp['adj_close'], label=key)

ax.legend()
plt.show()

This solution might be more relevant if you want more control in matlab.

The solution with copying 32-bit libs over to 64-bit did not work for me. What worked was unchecking Target Platform Prefer 32-bit check mark in project properties.

TLDR for Mac and Windows

docker run -it --rm alpine nslookup host.docker.internal

... prints the host's IP address ...

nslookup: can't resolve '(null)': Name does not resolve

Name:      host.docker.internal
Address 1: 192.168.65.2

Details

On Mac and Windows, you can use the special DNS name host.docker.internal.

The host has a changing IP address (or none if you have no network access). From 18.03 onwards our recommendation is to connect to the special DNS name host.docker.internal, which resolves to the internal IP address used by the host. This is for development purpose and will not work in a production environment outside of Docker Desktop for Mac.

You could also grab the attributes with the getAttribute() method which will return the value of a specific HTML attribute.

var elem = document.getElementById('the-span');_x000D_
_x000D_
var typeId = elem.getAttribute('data-typeId');_x000D_
var type   = elem.getAttribute('data-type');_x000D_
var points = elem.getAttribute('data-points');_x000D_
var important = elem.getAttribute('data-important');_x000D_
_x000D_
console.log(`typeId: ${typeId} | type: ${type} | points: ${points} | important: ${important}`_x000D_
);

<span data-typeId="123" data-type="topic" data-points="-1" data-important="true" id="the-span"></span>

it might save some time to somebody.

If you use GuzzleHttp and you face with this error message cURL error 60: SSL: no alternative certificate subject name matches target host name and you are fine with the 'insecure' solution (not recommended on production) then you have to add \GuzzleHttp\RequestOptions::VERIFY => false to the client configuration:

$this->client = new \GuzzleHttp\Client([
    'base_uri'                          => 'someAccessPoint',
    \GuzzleHttp\RequestOptions::HEADERS => [
        'User-Agent' => 'some-special-agent',
    ],
    'defaults'                          => [
        \GuzzleHttp\RequestOptions::CONNECT_TIMEOUT => 5,
        \GuzzleHttp\RequestOptions::ALLOW_REDIRECTS => true,
    ],
    \GuzzleHttp\RequestOptions::VERIFY  => false,
]);

which sets CURLOPT_SSL_VERIFYHOST to 0 and CURLOPT_SSL_VERIFYPEER to false in the CurlFactory::applyHandlerOptions() method

$conf[CURLOPT_SSL_VERIFYHOST] = 0;
$conf[CURLOPT_SSL_VERIFYPEER] = false;

From the GuzzleHttp documentation

verify

Describes the SSL certificate verification behavior of a request.

• Set to true to enable SSL certificate verification and use the default CA bundle > provided by operating system.
• Set to false to disable certificate verification (this is insecure!).
• Set to a string to provide the path to a CA bundle to enable verification using a custom certificate.

This Bootstrap listener is to start up and shut down Spring's root WebApplicationContext. As a web application can have multiple dispatcher servlet and each having its own application context containing controllers, view resolver, handler mappings etc But you might want to have service beans, DAO beans in root application context and want to use in all child application context(application context created by dispatcher servlets).

2nd use of this listener is when you want to use spring security.

for angular 4, the working solution was to do inside the component

@HostListener('window:scroll', ['$event']) onScrollEvent($event){
  console.log($event);
  console.log("scrolling");
} 

Check Below Codes :

1. SynchronousRequest

Swift 1.2

    let urlPath: String = "YOUR_URL_HERE"
    var url: NSURL = NSURL(string: urlPath)!
    var request1: NSURLRequest = NSURLRequest(URL: url)
    var response: AutoreleasingUnsafeMutablePointer<NSURLResponse?>=nil
    var dataVal: NSData =  NSURLConnection.sendSynchronousRequest(request1, returningResponse: response, error:nil)!
    var err: NSError
    println(response)
    var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(dataVal, options: NSJSONReadingOptions.MutableContainers, error: &err) as? NSDictionary
    println("Synchronous\(jsonResult)")

Swift 2.0 +

let urlPath: String = "YOUR_URL_HERE"
    let url: NSURL = NSURL(string: urlPath)!
    let request1: NSURLRequest = NSURLRequest(URL: url)
    let response: AutoreleasingUnsafeMutablePointer<NSURLResponse?>=nil


    do{

        let dataVal = try NSURLConnection.sendSynchronousRequest(request1, returningResponse: response)

            print(response)
            do {
                if let jsonResult = try NSJSONSerialization.JSONObjectWithData(dataVal, options: []) as? NSDictionary {
                    print("Synchronous\(jsonResult)")
                }
            } catch let error as NSError {

    cachePolicy: .useProtocolCachePolicy,
    timeoutInterval:60)
request.httpMethod = "POST" // POST ,GET, PUT What you want 

let session = URLSession.shared



  let dataTask = session.dataTask(with: request as URLRequest) {data,response,error in

do {
            if let jsonResult = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? NSDictionary {
                print("ASynchronous\(jsonResult)")
            }
        } catch let error as NSError {
            print(error.localizedDescription)
        }

    }
    dataTask.resume()

#import <Foundation/Foundation.h>
// clang -framework Foundation Siegfried.m 
    int
main() {
    NSArray *arr = @[
        @{@"1" : @"Fafner"},
        @{@"1" : @"Fasolt"}
    ];
    NSPredicate *p = [NSPredicate predicateWithFormat:
        @"SELF['1'] CONTAINS 'e'"];
    NSArray *res = [arr filteredArrayUsingPredicate:p];
    NSLog(@"Siegfried %@", res);
    return 0;
}

If you use MVC, tables, it works like this:

<td>@(((DateTime)detalle.fec).ToString("dd'/'MM'/'yyyy"))</td>

Multiple commands' output can be redirected. This works for either the command line or most usefully in a bash script. The -s directs the password prompt to the screen.

Hereblock cmds stdout/stderr are sent to seperate files and nothing to display.

sudo -s -u username <<'EOF' 2>err 1>out
ls; pwd;
EOF

Hereblock cmds stdout/stderr are sent to a single file and display.

sudo -s -u username <<'EOF' 2>&1 | tee out
ls; pwd;
EOF

Hereblock cmds stdout/stderr are sent to separate files and stdout to display.

sudo -s -u username <<'EOF' 2>err | tee out
ls; pwd;
EOF

Depending on who you are(whoami) and username a password may or may not be required.

I had c++ codes in my project but i didn't have NDK installed, installing it solved the problem

If you're like me and you use this method of passing variables a lot, here's a write-less-code solution.

In your node.js route, pass the variables in an object called window, like this:

router.get('/', function (req, res, next) {
    res.render('index', {
        window: {
            instance: instance
        }
    });
});

Then in your pug/jade layout file (just before the block content), you get them out like this:

if window
    each object, key in window
        script.
            window.!{key} = !{JSON.stringify(object)};

As my layout.pug file gets loaded with each pug file, I don't need to 'import' my variables over and over.

This way all variables/objects passed to window 'magically' end up in the real window object of your browser where you can use them in Reactjs, Angular, ... or vanilla javascript.

This is a quick and simple add of a named tab to the current worksheet:

Sheets.Add.Name = "Tempo"

Try this:

fname = "feed.txt"

num_lines = 0
num_words = 0
num_chars = 0

with open(fname, 'r') as f:
    for line in f:
        words = line.split()

        num_lines += 1
        num_words += len(words)
        num_chars += len(line)

Back to your code:

fname = "feed.txt"
fname = open('feed.txt', 'r')

what's the point of this? fname is a string first and then a file object. You don't really use the string defined in the first line and you should use one variable for one thing only: either a string or a file object.

for line in feed:
    lines = line.split('\n')

line is one line from the file. It does not make sense to split('\n') it.

Use this method after setContentView in onCreate() and pass the Window object by getWindow().

    public void makeActivityFullScreen(Window window){
    View decorView = window.getDecorView();
    //        int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
       window.getAttributes().layoutInDisplayCutoutMode = WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES;
    }
    decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE
            | View.SYSTEM_UI_FLAG_FULLSCREEN
            | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
    );
}

This code will work for notch screen also. To check the notch fullscreen you require android P but if You have a notch display phone then go to setting-->Display setting -->app display ratio --->select your app --->there will be two options safe are display and full screen , please select the full screen and run the app, you can see the fullscreen in notch also without having android Pie

I have use below code to encode the special character by specifying encode format.

String text = "This is an example é";
byte[] byteText = text.getBytes(Charset.forName("UTF-8"));
//To get original string from byte.
String originalString= new String(byteText , "UTF-8");

You need to add RouterMoudle into imports sections of the module containing the Header component

rising_edge is defined as:

FUNCTION rising_edge  (SIGNAL s : std_ulogic) RETURN BOOLEAN IS
BEGIN
    RETURN (s'EVENT AND (To_X01(s) = '1') AND
                        (To_X01(s'LAST_VALUE) = '0'));
END;

FUNCTION To_X01  ( s : std_ulogic ) RETURN  X01 IS
BEGIN
    RETURN (cvt_to_x01(s));
END;

CONSTANT cvt_to_x01 : logic_x01_table := (
                     'X',  -- 'U'
                     'X',  -- 'X'
                     '0',  -- '0'
                     '1',  -- '1'
                     'X',  -- 'Z'
                     'X',  -- 'W'
                     '0',  -- 'L'
                     '1',  -- 'H'
                     'X'   -- '-'
                    );

If your clock only goes from 0 to 1, and from 1 to 0, then rising_edge will produce identical code. Otherwise, you can interpret the difference.

Personally, my clocks only go from 0 to 1 and vice versa. I find rising_edge(clk) to be more descriptive than the (clk'event and clk = '1') variant.

Here is a function that works with jQuery (for height only, not width):

function setHeight(jq_in){
    jq_in.each(function(index, elem){
        // This line will work with pure Javascript (taken from NicB's answer):
        elem.style.height = elem.scrollHeight+'px'; 
    });
}
setHeight($('<put selector here>'));

Note: The op asked for a solution that does not use Javascript, however this should be helpful to many people who come across this question.

OIDs being phased out

The core team responsible for Postgres is gradually phasing out OIDs.

Postgres 12 removes special behavior of OID columns

The use of OID as an optional system column on your tables is now removed from Postgres 12. You can no longer use:

• CREATE TABLE … WITH OIDS command
• default_with_oids (boolean) compatibility setting

The data type OID remains in Postgres 12. You can explicitly create a column of the type OID.

After migrating to Postgres 12, any optionally-defined system column oid will no longer be invisible by default. Performing a SELECT * will now include this column. Note that this extra “surprise” column may break naïvely written SQL code.

C++20 std::format("{}"

https://en.cppreference.com/w/cpp/utility/format/formatter#Standard_format_specification claims that the default output format will be the string by default:

auto s6 = std::format("{:6}", true);  // value of s6 is "true  "

and:

The available bool presentation types are:

• none, s: Copies textual representation (true or false, or the locale-specific form) to the output.
• b, B, c, d, o, x, X: Uses integer presentation types with the value static_cast(value).

As usual, Gnuplot is a fantastic tool for plotting sweet looking graphs and it can be made to perform all sorts of calculations. However, it is intended to plot data rather than to serve as a calculator and it is often easier to use an external programme (e.g. Octave) to do the more "complicated" calculations, save this data in a file, then use Gnuplot to produce the graph. For the above problem, check out the "hist" function is Octave using [freq,bins]=hist(data), then plot this in Gnuplot using

set style histogram rowstacked gap 0
set style fill solid 0.5 border lt -1
plot "./data.dat" smooth freq with boxes

You can use the onejar-maven-plugin for packaging. Basically, it assembles your project and its dependencies in as one jar, including not just your project jar file, but also all external dependencies as a "jar of jars", e.g.

<build>
    <plugins>
        <plugin>
            <groupId>com.jolira</groupId>
            <artifactId>onejar-maven-plugin</artifactId>
                <version>1.4.4</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>one-jar</goal>
                        </goals>
                    </execution>
                </executions>
        </plugin>
    </plugins>
</build>

Note 1: Configuration options is available at the project home page.

Note 2: For one reason or the other, the onejar-maven-plugin project is not published at Maven Central. However jolira.com tracks the original project and publishes it to with the groupId com.jolira.

i made a method that merge cells and put border.

protected void setMerge(Sheet sheet, int numRow, int untilRow, int numCol, int untilCol, boolean border) {
    CellRangeAddress cellMerge = new CellRangeAddress(numRow, untilRow, numCol, untilCol);
    sheet.addMergedRegion(cellMerge);
    if (border) {
        setBordersToMergedCells(sheet, cellMerge);
    }

}



protected void setBordersToMergedCells(Sheet sheet, CellRangeAddress rangeAddress) {
    RegionUtil.setBorderTop(BorderStyle.MEDIUM, rangeAddress, sheet);
    RegionUtil.setBorderLeft(BorderStyle.MEDIUM, rangeAddress, sheet);
    RegionUtil.setBorderRight(BorderStyle.MEDIUM, rangeAddress, sheet);
    RegionUtil.setBorderBottom(BorderStyle.MEDIUM, rangeAddress, sheet);
}

You should put your password with 'p'

mysql -u root -u 1.1.1.1 -p'MyPass'

Window / Show Device Bezels

And now you can see the real device, so double tap on HOME button and kill you app

document.title="your title";

I prefer this.

Immediately after that line try closing the response using exit or die()

header($_SERVER["SERVER_PROTOCOL"]." 404 Not Found");
exit;

or

header($_SERVER["SERVER_PROTOCOL"]." 404 Not Found");
die();

It's possible using the button element.

<button name="name" value="value" type="submit">Sök</button>

From the W3C page on button:

Buttons created with the BUTTON element function just like buttons created with the INPUT element, but they offer richer rendering possibilities: the BUTTON element may have content.

UPDATE: Added a more detailed description of the formset errors.

Form.errors combines all field and non_field_errors. Therefore you can simplify the html to this:

template

    {% load form_tags %}

    {% if form.errors %}
    <div class="alert alert-danger alert-dismissible col-12 mx-1" role="alert">
        <div id="form_errors">
            {% for key, value in form.errors.items %}
                <span class="fieldWrapper">
                    {{ key }}:{{ value }}
                </span>
            {% endfor %}
        </div>
        <button type="button" class="close" data-dismiss="alert" aria-label="Close">
            <span aria-hidden="true">&times;</span>
        </button>
    </div>
    {% endif %}


If you want to generalise it you can create a list_errors.html which you include in every form template. It handles form and formset errors:

    {% if form.errors %}
    <div class="alert alert-danger alert-dismissible col-12 mx-1" role="alert">
        <div id="form_errors">

            {% for key, value in form.errors.items %}
                <span class="fieldWrapper">
                    {{ key }}:{{ value }}
                </span>
            {% endfor %}
        </div>
        <button type="button" class="close" data-dismiss="alert" aria-label="Close">
            <span aria-hidden="true">&times;</span>
        </button>
    </div>
    {% elif formset.total_error_count %}
    <div class="alert alert-danger alert-dismissible col-12 mx-1" role="alert">
        <div id="form_errors">
            {% if formset.non_form_errors %}
                {{ formset.non_form_errors }}
            {% endif %}
            {% for form in formset.forms %}
                {% if form.errors %}
                    Form number {{ forloop.counter }}:
                    <ul class="errorlist">
                    {% for key, error in form.errors.items %}
                        <li>{{form.fields|get_label:key}}
                            <ul class="errorlist">
                                <li>{{error}}</li>
                            </ul>
                        </li>
                    {% endfor %}
                    </ul>
                {% endif %}
            {% endfor %}

        </div>
    </div>

    {% endif %}

form_tags.py

from django import template

register = template.Library()


def get_label(a_dict, key):
    return getattr(a_dict.get(key), 'label', 'No label')


register.filter("get_label", get_label)

One caveat: In contrast to forms Formset.errors does not include non_field_errors.

This probably does not answer your question, but I had the same question and it answered mine.

I changed Private Function to Public Function and it worked.

This question is old and things have evolved in JavaScript. You can now do this:

const params = {}
document.location.search.substr(1).split('&').forEach(pair => {
  [key, value] = pair.split('=')
  params[key] = value
})

and you get params.year that contains 2008. You would also get other query params in your params object.

Edit: a shorter/cleaner way to do this:

const params = new Map(location.search.slice(1).split('&').map(kv => kv.split('=')))

You can then test if the year param exists with:

params.has('year')  // true

Or retrieve it with:

params.get('year')  // 2008

Edit 2020

You can convert URL params to an Object:

const params = location.search.slice(1).split('&').reduce((acc, s) => {
  const [k, v] = s.split('=')
  return Object.assign(acc, {[k]: v})
}, {})

Then it can be used as a regular JS Object:

params.year  // 2008

try this ^^

$(document).ready(function() {
        $("form").bind("keypress", function(e) {
            if (e.keyCode == 13) {
                return false;
            }
        });
    });

Hope this helps

TypeA[] array = (TypeA[]) a.toArray();

This is to do with JavaScript's + in operator - if a number and a string are "added" up, the number is converted into a string:

0 + 1; //1
'0' + 1; // '01'

To solve this, use the + unary operator, or use parseInt():

+'0' + 1; // 1
parseInt('0', 10) + 1; // 1

The unary + operator converts it into a number (however if it's a decimal it will retain the decimal places), and parseInt() is self-explanatory (converts into number, ignoring decimal places).

The second argument is necessary for parseInt() to use the correct base when leading 0s are placed:

parseInt('010'); // 8 in older browsers, 10 in newer browsers
parseInt('010', 10); // always 10 no matter what

There's also parseFloat() if you need to convert decimals in strings to their numeric value - + can do that too but it behaves slightly differently: that's another story though.

You should be able to perform a select on the orders table, using a raw WHERE to find the max(id) in a subquery, like this:

 \DB::table('orders')->where('id', \DB::raw("(select max(`id`) from orders)"))->get();

If you want to use Eloquent (for example, so you can convert your response to an object) you will want to use whereRaw, because some functions such as toJSON or toArray will not work without using Eloquent models.

 $order = Order::whereRaw('id = (select max(`id`) from orders)')->get();

That, of course, requires that you have a model that extends Eloquent.

 class Order extends Eloquent {}

As mentioned in the comments, you don't need to use whereRaw, you can do the entire query using the query builder without raw SQL.

 // Using the Query Builder
 \DB::table('orders')->find(\DB::table('orders')->max('id'));

 // Using Eloquent
 $order = Order::find(\DB::table('orders')->max('id'));

(Note that if the id field is not unique, you will only get one row back - this is because find() will only return the first result from the SQL server.).

Full version:

<? echo date('F Y'); ?>

Short version:

<? echo date('M Y'); ?>

Here is a good reference for the different date options.

update

To show the previous month we would have to introduce the mktime() function and make use of the optional timestamp parameter for the date() function. Like this:

echo date('F Y', mktime(0, 0, 0, date('m')-1, 1, date('Y')));

This will also work (it's typically used to get the last day of the previous month):

echo date('F Y', mktime(0, 0, 0, date('m'), 0, date('Y')));

Hope that helps.

A React Node is one of the following types:

• Boolean (which is ignored)
• null or undefined (which is ignored)
• Number
• String
• A React element (result of JSX)
• An array of any of the above, possibly a nested one

you can returns a private collection named HttpValueCollection even the documentation says it's a NameValueCollection using the ParseQueryString utility. Then add the keys manually, HttpValueCollection do the encoding for you. And then just append the QueryString manually :

var qs = HttpUtility.ParseQueryString(""); 
qs.Add("name", "John")
qs.Add("contact", "calgary");
qs.Add("contact", "vancouver")

<a href="<%: Url.Action("GetByList", "Listing")%>?<%:qs%>">
    <span>People</span>
</a>

According to Google documentation they said that this is the best way to do it. First create this function to find out how many markers there are/

   function setMapOnAll(map1) {
    for (var i = 0; i < markers.length; i++) {
      markers[i].setMap(map1);
    }
  }

Next create another function to take away all these markers

 function clearMarker(){
setMapOnAll(null);
}

Then create this final function to erase all the markers when ever this function is called upon.

 function delateMarkers(){
clearMarker()
markers = []
//console.log(markers) This is just if you want to

}

Hope that helped good luck

This answer was first posted here: cordova/phonegap does not make android directory

With the release of Cordova 3.3.0, it seems the PhoneGap team is trying to address the naming confusion. The documentations have been updated to recommend people using the cordova command instead. Do not use the phonegap command anymore.

Here is a fresh installation guide for a guaranteed trouble free set up:

1. Install Cordova (forget the name PhoneGap from now on). For PC:

   C:> npm install -g cordova

2. From command prompt, navigate to the folder you want to create your project using:

   cordova create hello com.example.hello HelloWorld
   cd hello

3. Define the OS you want to suppport for example:

   cordova platform add wp8

4. Install plugins (If needed). For example we want the following:

   cordova plugin add org.apache.cordova.device
   cordova plugin add org.apache.cordova.camera
   cordova plugin add org.apache.cordova.media-capture
   cordova plugin add org.apache.cordova.media
   

5. Finally, generate the app using:

   cordova build wp8

Here is a link to the PhoneGapCordova 3.3.0 Documentation http://docs.phonegap.com/en/3.3.0/guide_cli_index.md.html#The%20Command-Line%20Interface

My problem was different to any of the above as far as I can tell. I had a working version 1.1 of Android Studio and upgraded to 1.2 Then I got the JAVA_HOME error when starting 1.2

The problem was that my JAVA_HOME was set to "C:\Program Files\Java\jdk1.8.0_20" with quotation marks included. I haven't put them there to quote the string, the quotation marks were in the Variable Value field. It appears that 1.1 is happy with the quotes being there but 1.2 is not.

Removing quotes removed the error and 1.2 now opens fine

I had issues with some of the above solutions, with getting the correct "bounding_box" or new size of the image. Therefore here is my version

def rotation(image, angleInDegrees):
    h, w = image.shape[:2]
    img_c = (w / 2, h / 2)

    rot = cv2.getRotationMatrix2D(img_c, angleInDegrees, 1)

    rad = math.radians(angleInDegrees)
    sin = math.sin(rad)
    cos = math.cos(rad)
    b_w = int((h * abs(sin)) + (w * abs(cos)))
    b_h = int((h * abs(cos)) + (w * abs(sin)))

    rot[0, 2] += ((b_w / 2) - img_c[0])
    rot[1, 2] += ((b_h / 2) - img_c[1])

    outImg = cv2.warpAffine(image, rot, (b_w, b_h), flags=cv2.INTER_LINEAR)
    return outImg

Here is some LESS for you, in case you customize the navbar:

.navbar .divider-vertical {
    height: floor(@navbar-height - @navbar-margin-bottom);
    margin: floor(@navbar-margin-bottom / 2) 9px;
    border-left: 1px solid #f2f2f2;
    border-right: 1px solid #ffffff;
}

There is no native indexof method in java arrays.You will need to write your own method for this.

i was using

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

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

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

now its works fine

try this

$sql= " INSERT INTO users (username, password) VALUES('test', 'test') ";
mysql_query($sql);
$user_id= mysql_insert_id();
if(!empty($user_id) {

$sql=INSERT INTO profiles (userid, bio, homepage) VALUES($user_id,'Hello world!', 'http://www.stackoverflow.com');
/* or 
 $sql=INSERT INTO profiles (userid, bio, homepage) VALUES(LAST_INSERT_ID(),'Hello   world!', 'http://www.stackoverflow.com'); */
 mysql_query($sql);
};

I used pychart and thought it was very straightforward.

http://home.gna.org/pychart/

It's all native python and does not have a busload of dependencies. I'm sure matplotlib is lovely but I'd be downloading and installing for days and I just want one measley bar chart!

It doesn't seem to have been updated in a few years but hey it works!

Invariant is a linguistically appropriate type of comparison.
Ordinal is a binary type of comparison. (faster)

In my case I use a template component in Blazor.

 <BTable ID="Table1" TotalRows="MyList.Count()">

The problem is calling a method (Count) in the component header. To resolve the problem I changed it like this :

int total = MyList.Count();

and later :

<BTable ID="Table1" TotalRows="total">

The difference is that Any is an extension method for any IEnumerable<T> defined on System.Linq.Enumerable. It can be used on any IEnumerable<T> instance.

Exists does not appear to be an extension method. My guess is that coll is of type List<T>. If so Exists is an instance method which functions very similar to Any.

In short, the methods are essentially the same. One is more general than the other.

• Any also has an overload which takes no parameters and simply looks for any item in the enumerable.
• Exists has no such overload.

I know this is an old question but since none of the answers mentioned the large object heap, this might be of use to others who find this question ...

Any memory allocation in .NET that is over 85,000 bytes comes from the large object heap (LOH) not the normal small object heap. Why does this matter? Because the large object heap is not compacted. Which means that the large object heap gets fragmented and in my experience this inevitably leads to out of memory errors.

In the original question the list has 50,000 items in it. Internally a list uses an array, and assuming 32 bit that requires 50,000 x 4bytes = 200,000 bytes (or double that if 64 bit). So that memory allocation is coming from the large object heap.

So what can you do about it?

If you are using a .net version prior to 4.5.1 then about all you can do about it is to be aware of the problem and try to avoid it. So, in this instance, instead of having a list of vehicles you could have a list of lists of vehicles, provided no list ever had more than about 18,000 elements in it. That can lead to some ugly code, but it is viable work around.

If you are using .net 4.5.1 or later then the behaviour of the garbage collector has changed subtly. If you add the following line where you are about to make large memory allocations:

System.Runtime.GCSettings.LargeObjectHeapCompactionMode = System.Runtime.GCLargeObjectHeapCompactionMode.CompactOnce;

it will force the garbage collector to compact the large object heap - next time only.

It might not be the best solution but the following has worked for me:

int tries = 0;
while (tries++ < 2)
{
  try 
  {
    . . some large allocation . .
    return;
  }
  catch (System.OutOfMemoryException)
  {
    System.Runtime.GCSettings.LargeObjectHeapCompactionMode = System.Runtime.GCLargeObjectHeapCompactionMode.CompactOnce;
    GC.Collect();
  }
}

of course this only helps if you have the physical (or virtual) memory available.

1. Connect Android device to PC via USB cable and turn on USB storage.
2. Copy .apk file to attached device's storage.
3. Turn off USB storage and disconnect it from PC.
4. Check the option Settings ? Applications ? Unknown sources OR Settings > Security > Unknown Sources.
5. Open FileManager app and click on the copied .apk file. If you can't fine the apk file try searching or allowing hidden files. It will ask you whether to install this app or not. Click Yes or OK.

This procedure works even if ADB is not available.

You can approximate a rolling average by applying a weighted average on your input stream.

template <unsigned N>
double approxRollingAverage (double avg, double input) {
    avg -= avg/N;
    avg += input/N;
    return avg;
}

This way, you don't need to maintain 1000 buckets. However, it is an approximation, so it's value will not match exactly with a true rolling average.

Edit: Just noticed @steveha's post. This is equivalent to the exponential moving average, with the alpha being 1/N (I was taking N to be 1000 in this case to simulate 1000 buckets).

Number of answer have been given even though I would like to give mine command . I used to frequently. It may help to someone.

mongoimport original.json -d databaseName -c yourcollectionName --jsonArray --drop

Starting from Java 9, there is a new utility method allowing to create an immutable entry which is Map#entry(Object, Object).

Here is a simple example:

Entry<String, String> entry = Map.entry("foo", "bar");

As it is immutable, calling setValue will throw an UnsupportedOperationException. The other limitations are the fact that it is not serializable and null as key or value is forbidden, if it is not acceptable for you, you will need to use AbstractMap.SimpleImmutableEntry or AbstractMap.SimpleEntry instead.

NB: If your need is to create directly a Map with 0 to up to 10 (key, value) pairs, you can instead use the methods of type Map.of(K key1, V value1, ...).

It is not possible yet to search for content using multiple tags, for now only single tags are supported.

Firstly, the Instagram API endpoint "tags" required OAuth authentication.

This is not quite true, you only need an API-Key. Just register an application and add it to your requests. Example:

https://api.instagram.com/v1/users/userIdYouWantToGetMediaFrom/media/recent?client_id=yourAPIKey

Also note that the username is not the user-id. You can look up user-Id`s here.

A workaround for searching multiple keywords would be if you start one request for each tag and compare the results on your server. Of course this could slow down your site depending on how much keywords you want to compare.

Try this :

SELECT
    (
      SELECT
          `NAME`
      FROM
          locations
      WHERE
          ID = school_locations.LOCATION_ID
    ) as `NAME`
FROM
     school_locations
WHERE
     (
      SELECT
          `TYPE`
      FROM
          locations
      WHERE
          ID = school_locations.LOCATION_ID
     ) = 'coun';

Run this command:

npm install --save node-sass

This does the same as above. Similarly to the answer above.

The existing answers are better for how to get the correct value, but I can at least explain why getrusage isn't working for you.

man 2 getrusage:

The above struct [rusage] was taken from BSD 4.3 Reno. Not all fields are meaningful under Linux. Right now (Linux 2.4, 2.6) only the fields ru_utime, ru_stime, ru_minflt, ru_majflt, and ru_nswap are maintained.

I had a bunch of FKs to alter, so I wrote something to make the statements for me. Figured I'd share:

SELECT

CONCAT('ALTER TABLE `' ,rc.TABLE_NAME,
    '` DROP FOREIGN KEY `' ,rc.CONSTRAINT_NAME,'`;')
, CONCAT('ALTER TABLE `' ,rc.TABLE_NAME,
    '` ADD CONSTRAINT `' ,rc.CONSTRAINT_NAME ,'` FOREIGN KEY (`',kcu.COLUMN_NAME,
    '`) REFERENCES `',kcu.REFERENCED_TABLE_NAME,'` (`',kcu.REFERENCED_COLUMN_NAME,'`) ON DELETE CASCADE;')

FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS rc
LEFT OUTER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE kcu
    ON kcu.TABLE_SCHEMA = rc.CONSTRAINT_SCHEMA
    AND kcu.CONSTRAINT_NAME = rc.CONSTRAINT_NAME
WHERE DELETE_RULE = 'NO ACTION'
AND rc.CONSTRAINT_SCHEMA = 'foo'

Functions actually defined in other source files should only be declared in headers. In this case, you should use extern when declaring the prototype in a header.

Most of the time, your functions will be one of the following (more like a best practice):

• static (normal functions that aren't visible outside that .c file)
• static inline (inlines from .c or .h files)
• extern (declaration in headers of the next kind (see below))
• [no keyword whatsoever] (normal functions meant to be accessed using extern declarations)

Apply 100% width and height to your image:

<div style="height:42px;width:42px">
  <img src="http://someimage.jpg" style="width:100%; height:100%">
</div>

This way it will same size of its parent.

You can use this

(new SelectElement(driver.FindElement(By.Id(""))).SelectByText("");

I also faced same problem. But then I realised that the versions I am using of support libraries was not same.

Once I made it same, the error gone.

In your case

implementation 'com.android.support:appcompat-v7:27.1.0'
implementation 'com.android.support:design:27.0.2'

are not same, so you just downgraded appcompat to

implementation 'com.android.support:appcompat-v7:27.0.2'

hence, your problem solved.

But you could also have solved if you could have upgraded support design version to

implementation 'com.android.support:design:27.1.0'

Partial Functional Dependency occurs only in relation with composite keys. Partial functional dependency occurs when one or more non key attribute are depending on a part of the primary key.

Example:

Table: Stud_id, Course_id, Stud_name, Course_Name

Where: Primary Key = Stud_id + Course_id

Then: To determine name of student we use only Stud_id, which is part of primary key.

{Stud_id} -> {Stud_Name}

Hence,Stud_name is partially dependent on Stud_id. This is called partial dependency.

Some time this problem occur due to incompatible java version and tomcat version.Choose the compatible version of both.

And of course there are many implementations of Metro UI for WPF: https://github.com/MahApps/MahApps.Metro http://mosaicproject.codeplex.com/

1. As per Google's documentation, you should use Google's AP Client Library that makes this (token verification, claim extraction etc.) much easier than writing your own custom code.

2. From a performance perspective, the token should be parsed locally without making a call to Google again. Off-course Google's public key is needed and retrieval of that key is done using a caching strategy, implemented in the Google's client library from #1 above.

3. FYI only. Google also uses a JWT token. See image below for reference.

Inspired by @ford04 answer I use this hook, which also takes callbacks for success, errors, finally and an abortFn:

export const useAsync = (
        asyncFn, 
        onSuccess = false, 
        onError = false, 
        onFinally = false, 
        abortFn = false
    ) => {

    useEffect(() => {
        let isMounted = true;
        const run = async () => {
            try{
                let data = await asyncFn()
                if (isMounted && onSuccess) onSuccess(data)
            } catch(error) {
                if (isMounted && onError) onSuccess(error)
            } finally {
                if (isMounted && onFinally) onFinally()
            }
        }
        run()
        return () => {
            if(abortFn) abortFn()
            isMounted = false
        };
    }, [asyncFn, onSuccess])
}

If the asyncFn is doing some kind of fetch from back-end it often makes sense to abort it when the component is unmounted (not always though, sometimes if ie. you're loading some data into a store you might as well just want to finish it even if component is unmounted)

The answer to the question was already posted by the @latemail in the comments above. You can use regular expressions for the second and subsequent arguments of filter like this:

dplyr::filter(df, !grepl("RTB",TrackingPixel))

Since you have not provided the original data, I will add a toy example using the mtcars data set. Imagine you are only interested in cars produced by Mazda or Toyota.

mtcars$type <- rownames(mtcars)
dplyr::filter(mtcars, grepl('Toyota|Mazda', type))

   mpg cyl  disp  hp drat    wt  qsec vs am gear carb           type
1 21.0   6 160.0 110 3.90 2.620 16.46  0  1    4    4      Mazda RX4
2 21.0   6 160.0 110 3.90 2.875 17.02  0  1    4    4  Mazda RX4 Wag
3 33.9   4  71.1  65 4.22 1.835 19.90  1  1    4    1 Toyota Corolla
4 21.5   4 120.1  97 3.70 2.465 20.01  1  0    3    1  Toyota Corona

If you would like to do it the other way round, namely excluding Toyota and Mazda cars, the filter command looks like this:

dplyr::filter(mtcars, !grepl('Toyota|Mazda', type))

_mkdir will also do the job.

_mkdir("D:\\test");

A view represents a virtual table. You can join multiple tables in a view and use the view to present the data as if the data were coming from a single table.

A stored procedure uses parameters to do a function... whether it is updating and inserting data, or returning single values or data sets.

Creating Views and Stored Procedures - has some information from Microsoft as to when and why to use each.

Say I have two tables:

• tbl_user, with columns: user_id, user_name, user_pw
• tbl_profile, with columns: profile_id, user_id, profile_description

So, if I find myself querying from those tables A LOT... instead of doing the join in EVERY piece of SQL, I would define a view like:

CREATE VIEW vw_user_profile
AS
  SELECT A.user_id, B.profile_description
  FROM tbl_user A LEFT JOIN tbl_profile B ON A.user_id = b.user_id
GO

Thus, if I want to query profile_description by user_id in the future, all I have to do is:

SELECT profile_description FROM vw_user_profile WHERE user_id = @ID

That code could be used in a stored procedure like:

CREATE PROCEDURE dbo.getDesc
    @ID int
AS
BEGIN
    SELECT profile_description FROM vw_user_profile WHERE user_id = @ID
END
GO

So, later on, I can call:

dbo.getDesc 25

and I will get the description for user_id 25, where the 25 is your parameter.

There is obviously a lot more detail, this is just the basic idea.

This is how I did it.

            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

                    JFileChooser fileChooser = new JFileChooser();

You can use the provider-specific ConnectionStringBuilder class (within the appropriate namespace), or System.Data.Common.DbConnectionStringBuilder to abstract the connection string object if you need to. You'd need to know the provider-specific keywords used to designate the information you're looking for, but for a SQL Server example you could do either of these two things:

System.Data.SqlClient.SqlConnectionStringBuilder builder = new System.Data.SqlClient.SqlConnectionStringBuilder(connectionString);

string server = builder.DataSource;
string database = builder.InitialCatalog;

or

System.Data.Common.DbConnectionStringBuilder builder = new System.Data.Common.DbConnectionStringBuilder();

builder.ConnectionString = connectionString;

string server = builder["Data Source"] as string;
string database = builder["Initial Catalog"] as string;

I used a style to solve this issue. The official link is here.

Pretty useful stuff. You make a file to hold your styles (like "styles.xml"), and define them inside it. You then reference the styles in your layout (like "main.xml").

Here's a sample style that does what you want:

<style name="text_line_spacing">
   <item name="android:lineSpacingMultiplier">1.4</item>
</style>

Let's say you want to alter a simple TextView with this. In your layout file you'd type:

<TextView
   style="@style/summary_text"
   ...
   android:text="This sentence has 1.4 times more spacing than normal."
/>

Try it--this is essentially how all the built-in UI is done on the android. And by using styles, you have the option to modify all sorts of other aspects of your Views as well.

If the format is "fixed" meaning you don't have to use other format you can have pure JavaScript instead of using whole library to format the date:

//Pad given value to the left with "0"_x000D_
function AddZero(num) {_x000D_
    return (num >= 0 && num < 10) ? "0" + num : num + "";_x000D_
}_x000D_
_x000D_
window.onload = function() {_x000D_
    var now = new Date();_x000D_
    var strDateTime = [[AddZero(now.getDate()), _x000D_
        AddZero(now.getMonth() + 1), _x000D_
        now.getFullYear()].join("/"), _x000D_
        [AddZero(now.getHours()), _x000D_
        AddZero(now.getMinutes())].join(":"), _x000D_
        now.getHours() >= 12 ? "PM" : "AM"].join(" ");_x000D_
    document.getElementById("Console").innerHTML = "Now: " + strDateTime;_x000D_
};

<div id="Console"></div>

The variable strDateTime will hold the date/time in the format you desire and you should be able to tweak it pretty easily if you need.

I'm using join as good practice, nothing more, it's better than adding strings together.

The proper data type for "2010-12-20 00:00:00.0000000" value is DATETIME2(7) / DT_DBTIME2 ().

But used data type for CYCLE_DATE field is DATETIME - DT_DATE. This means milliseconds precision with accuracy down to every third millisecond (yyyy-mm-ddThh:mi:ss.mmL where L can be 0,3 or 7).

The solution is to change CYCLE_DATE date type to DATETIME2 - DT_DBTIME2.

Thought I'd add a bit to the answer.

If you have multiple URL definitions then you'll have to name each of them separately. So you lose the flexibility when calling reverse since one reverse will expect a parameter while the other won't.

Another way to use regex to accommodate the optional parameter:

r'^project_config/(?P<product>\w+)/((?P<project_id>\w+)/)?$'

Try the following commands to search the string inside all previous tracked files:

git log --patch  | less +/searching_string

or

git rev-list --all | GIT_PAGER=cat xargs git grep 'search_string'

which needs to be run from the parent directory where you'd like to do the searching.

Interfaces can not contain any implementation (including default values). You need to switch to abstract class.

I had a similar problem using android 5.0 with a bad parent activity name

<activity
        android:name=".DisplayMessageActivity"
        android:label="@string/title_activity_display_message"
        android:parentActivityName=".MainActivity" >
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.example.myfirstapp.MainActivity" />
    </activity>

I removed the com.example.myfirstapp from the parent activity name and it worked properly

If you are writing code in Swift it would look as an example like this

func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String?
{
    switch section
    {
        case 0:
            return "Apple Devices"
        case 1:
            return "Samsung Devices"
        default:
            return "Other Devices"
    }
}

If you use the OOP method of inserting, you don't need to worry about mass-action/fillable properties:

$user = new User;
$user->username = 'Stevo';
$user->email = '[email protected]';
$user->password = '45678';
$user->save();

The issue because of not loading jquery ui library.

https://code.jquery.com/ui/1.11.4/jquery-ui.js - CDN source file

Call above path in your file.

The list is maintaining an object reference to the original value stored in the list. So when you execute this line:

Integer x = i.next();

Both x and the list are storing a reference to the same object. However, when you execute:

x = Integer.valueOf(9);

nothing has changed in the list, but x is now storing a reference to a different object. The list has not changed. You need to use some of the list manipulation methods, such as

list.set(index, Integer.valueof(9))

Note: this has nothing to do with the immutability of Integer, as others are suggesting. This is just basic Java object reference behaviour.

Here's a complete example, to help explain the point. Note that this makes use of the ListIterator class, which supports removing/setting items mid-iteration:

import java.util.*;

public class ListExample {

  public static void main(String[] args) {

    List<Foo> fooList = new ArrayList<Foo>();
    for (int i = 0; i < 9; i++)
      fooList.add(new Foo(i, i));

    // Standard iterator sufficient for altering elements
    Iterator<Foo> iterator = fooList.iterator();

    if (iterator.hasNext()) {
      Foo foo = iterator.next();
      foo.x = 99;
      foo.y = 42;
    }

    printList(fooList);    

    // List iterator needed for replacing elements
    ListIterator<Foo> listIterator = fooList.listIterator();

    if (listIterator.hasNext()) {
      // Need to call next, before set.
      listIterator.next();
      // Replace item returned from next()
      listIterator.set(new Foo(99,99));
    }

    printList(fooList);
  }

  private static void printList(List<?> list) {
    Iterator<?> iterator = list.iterator();
    while (iterator.hasNext()) {
      System.out.print(iterator.next());
    }
    System.out.println();
  }

  private static class Foo {
    int x;
    int y;

    Foo(int x, int y) {
      this.x = x;
      this.y = y;
    }

    @Override
    public String toString() {
      return String.format("[%d, %d]", x, y);
    }
  }
}

This will print:

[99, 42][1, 1][2, 2][3, 3][4, 4][5, 5][6, 6][7, 7][8, 8]
[99, 99][1, 1][2, 2][3, 3][4, 4][5, 5][6, 6][7, 7][8, 8]

It's time I post an answer about RVO, me too...

If you return an object by value, the compiler often optimizes this so it doesn't get constructed twice, since it's superfluous to construct it in the function as a temporary and then copy it. This is called return value optimization: the created object will be moved instead of being copied.

Solution without creating Service, using $rootScope:

To share properties across app Controllers you can use Angular $rootScope. This is another option to share data, putting it so that people know about it.

The preferred way to share some functionality across Controllers is Services, to read or change a global property you can use $rootscope.

var app = angular.module('mymodule',[]);
app.controller('Ctrl1', ['$scope','$rootScope',
  function($scope, $rootScope) {
    $rootScope.showBanner = true;
}]);

app.controller('Ctrl2', ['$scope','$rootScope',
  function($scope, $rootScope) {
    $rootScope.showBanner = false;
}]);

Using $rootScope in a template (Access properties with $root):

<div ng-controller="Ctrl1">
    <div class="banner" ng-show="$root.showBanner"> </div>
</div>

.on() is for jQuery version 1.7 and above. If you have an older version, use this:

$("#SomeId").live("click",function(){
    //do stuff;
});

where date_dt = to_date(to_char(sysdate-1, 'YYYY-MM-DD') || ' 19:16:08', 'YYYY-MM-DD HH24:MI:SS') 

should work.

Below is the code which can be use to find the mode of a vector variable in R.

a <- table([vector])

names(a[a==max(a)])

This article has a good discussion on this issue. You can use

SELECT * 
FROM Y
INNER JOIN X ON EXISTS(SELECT X.QID 
                       INTERSECT 
                       SELECT y.QID);

In Oracle PL/SQL, if you are running a query that may return multiple rows, you need a cursor to iterate over the results. The simplest way is with a for loop, e.g.:

declare
  myname varchar2(20) := 'tom';
begin
  for result_cursor in (select * from mytable where first_name = myname) loop
    dbms_output.put_line(result_cursor.first_name);
    dbms_output.put_line(result_cursor.other_field);
  end loop;
end;

If you have a query that returns exactly one row, then you can use the select...into... syntax, e.g.:

declare 
  myname varchar2(20);
begin
  select first_name into myname 
    from mytable 
    where person_id = 123;
end;

Template/HTML File (component.ts)

<select>
 <option *ngFor="let v of values" [value]="v" (ngModelChange)="onChange($event)">  
    {{v.name}}
  </option>
</select>

Typescript File (component.ts)

values = [
  { id: 3432, name: "Recent" },
  { id: 3442, name: "Most Popular" },
  { id: 3352, name: "Rating" }
];

onChange(cityEvent){
    console.log(cityEvent); // It will display the select city data
}

(ngModelChange) is the @Output of the ngModel directive. It fires when the model changes. You cannot use this event without the ngModel directive

This worked for me:

I need to decrypt a password. The password is crypted with password_hash function.

$password = 'examplepassword';
$crypted = password_hash($password, PASSWORD_DEFAULT);

Its not clear to me if you need password_verify, or you are trying to gain unauthorized access to the application or database. Other have talked about password_verify, so here's how you could gain unauthorized access. Its what bad guys often do when they try to gain access to a system.

First, create a list of plain text passwords. A plain text list can be found in a number of places due to the massive data breaches from companies like Adobe. Sort the list and then take the top 10,000 or 100,000 or so.

Second, create a list of digested passwords. Simply encrypt or hash the password. Based on your code above, it does not look like a salt is being used (or its a fixed salt). This makes the attack very easy.

Third, for each digested password in the list, perform a select in an attempt to find a user who is using the password:

$sql_script = 'select * from USERS where password="'.$digested_password.'"'

Fourth, profit.

So, rather than picking a user and trying to reverse their password, the bad guy picks a common password and tries to find a user who is using it. Odds are on the bad guy's side...

Because the bad guy does these things, it would behove you to not let users choose common passwords. In this case, take a look at ProCheck, EnFilter or Hyppocrates (et al). They are filtering libraries that reject bad passwords. ProCheck achieves very high compression, and can digest multi-million word password lists into a 30KB data file.

You were just missing the second half of the column statement telling it to remove the entire column, since most normal Ranges start with a Column Letter, it was looking for a number and didn't get one. The ":" gets the whole column, or row.

I think what you were looking for in your Range was this:

Range("C:C,F:F,I:I,L:L,O:O,R:R").Delete

Just change the column letters to match your needs.

String user = request.getParameter("uname");
out.println(user); 
String pass = request.getParameter("pass");
out.println(pass); 
Class.forName( "com.mysql.jdbc.Driver" );
Connection conn = DriverManager.getConnection( "jdbc:mysql://localhost:3306/rental","root","root" ) ;
out.println("hello");
Statement st = conn.createStatement();
String sql = "insert into login (user,pass) values('" + user + "','" + pass + "')";
st.executeUpdate(sql);

Short answer, you can't.

HTML is used for the page's structure and can't send e-mails, you will need a server side language (such as PHP) to send e-mails, you can also use a third party service and let them handle the e-mail sending for you.

No, Not if your website is on a remote server, i.e not on localhost.

Use the finish method. It is the simpler and easier method.

this.finish();

jQuery's attr method returns the value of the attribute:

The .attr() method gets the attribute value for only the first element in the matched set. To get the value for each element individually, use a looping construct such as jQuery's .each() or .map() method.

All you need is:

$('html').attr('lang') == 'fr-FR'

However, you might want to do a case-insensitive match:

$('html').attr('lang').toLowerCase() === 'fr-fr'

jQuery's val method returns the value of a form element.

The .val() method is primarily used to get the values of form elements such as input, select and textarea. In the case of <select multiple="multiple"> elements, the .val() method returns an array containing each selected option; if no option is selected, it returns null.

No other answer covers this method, so:

I find by far the most useful, simple, and reliable method is to ask your database. For example on Linux for Postgres you might do:

sudo su postgres
tail -f /var/log/postgresql/postgresql-8.4-main.log

Each database will have slightly different procedure. In the database logs you'll see not only the raw SQL, but any connection setup or transaction overhead django is placing on the system.

1. Make sure your app is mentioned in installed_apps in settings.py
2. Make sure you model class extends models.Model

It's not really an IDE per se, but I really like TextMate, and with the C++ bundle that ships with it, it can do a lot of the things you'd find in an IDE (without all the bloat!).

The standard principle is separate event handlers shouldn't depend upon the order they are called. If they do depend upon the order they should not be separate.

Otherwise, you register one event handler as being 'first' and someone else then registers their event handler as 'first' and you're back in the same mess as before.

Though this is an old post, I am posting how I resolved in case it helps others. Since I used sudo to do the install of the boto3 library the permissions on the boto3 directory was set to 700. Either change the permissions to be readable by others or run the python command as sudo.

Or with Prototype:

Event.observe(this, 'load', function() { new Ajax.Request(... ) );

Or better, define the function elsewhere rather than inline, then:

Event.observe(this, 'load', functionName );

You don't have to use jQuery or Prototype specifically, but I hope you're using some kind of library. Either library is going to handle the event handling in a more consistent manner than onload, and of course is going to make it much easier to process the Ajax call. If you must use the body onload attribute, then you should just be able to call the same function as referenced in these examples (onload="javascript:functionName();").

However, if your database update doesn't depend on the rendering on the page, why wait until it's fully loaded? You could just include a call to the Ajax-calling function at the end of the JavaScript on the page, which should give nearly the same effect.

I know that this has already been answered, but I wanted to share an answer that I gave to someone who asked a very similar question on a C/C++ Facebook group.

Arrays don't have assignment operator functions*. This means that you cannot simply assign a char array to a string literal. Why? Because the array itself doesn't have any assignment operator. (*It's a const pointer which can't be changed.)

arrays are simply an area of contiguous allocated memory and the name of the array is actually a pointer to the first element of the array. (Quote from https://www.quora.com/Can-we-copy-an-array-using-an-assignment-operator)

To copy a string literal (such as "Hello world" or "abcd") to your char array, you must manually copy all char elements of the string literal onto the array.

char s[100]; This will initialize an empty array of length 100.

Now to copy your string literal onto this array, use strcpy

strcpy(s, "abcd"); This will copy the contents from the string literal "abcd" and copy it to the s[100] array.

Here's a great example of what it's doing:

int i = 0; //start at 0
do {
    s[i] = ("Hello World")[i]; //assign s[i] to the string literal index i
} while(s[i++]); //continue the loop until the last char is null

You should obviously use strcpy instead of this custom string literal copier, but it's a good example that explains how strcpy fundamentally works.

Hope this helps!

Here is an extension method that overloads the AppendText method with a color parameter:

public static class RichTextBoxExtensions
{
    public static void AppendText(this RichTextBox box, string text, Color color)
    {
        box.SelectionStart = box.TextLength;
        box.SelectionLength = 0;

        box.SelectionColor = color;
        box.AppendText(text);
        box.SelectionColor = box.ForeColor;
    }
}

And this is how you would use it:

var userid = "USER0001";
var message = "Access denied";
var box = new RichTextBox
              {
                  Dock = DockStyle.Fill,

Note that you may notice some flickering if you're outputting a lot of messages. See this C# Corner article for ideas on how to reduce RichTextBox flicker.

Someone should mention that in the question there is a little trap. #ifdef will only check if the following symbol has been defined via #define or by command line, but its value (its substitution in fact) is irrelevant. You could even write

#define one

precompilers accept that. But if you use #if it's another thing.

#define one 0
#if one
    printf("one evaluates to a truth ");
#endif
#if !one
    printf("one does not evaluate to truth ");
#endif

will give one does not evaluate to truth. The keyword defined allows to get the desired behaviour.

#if defined(one) 

is therefore equivalent to #ifdef

The advantage of the #if construct is to allow a better handling of code paths, try to do something like that with the old #ifdef/#ifndef pair.

#if defined(ORA_PROC) || defined(__GNUC) && __GNUC_VERSION > 300

Bandwidth is tiered by instance size, here's a comprehensive answer:

For t2/m3/c3/c4/r3/i2/d2 instances:

• t2.nano = ??? (Based on the scaling factors, I'd expect 20-30 MBit/s)
• t2.micro = ~70 MBit/s (qiita says 63 MBit/s) - t1.micro gets about ~100 Mbit/s
• t2.small = ~125 MBit/s (t2, qiita says 127 MBit/s, cloudharmony says 125 Mbit/s with spikes to 200+ Mbit/s)
• *.medium = t2.medium gets 250-300 MBit/s, m3.medium ~400 MBit/s
• *.large = ~450-600 MBit/s (the most variation, see below)
• *.xlarge = 700-900 MBit/s
• *.2xlarge = ~1 GBit/s +- 10%
• *.4xlarge = ~2 GBit/s +- 10%
• *.8xlarge and marked specialty = 10 Gbit, expect ~8.5 GBit/s, requires enhanced networking & VPC for full throughput

m1 small, medium, and large instances tend to perform higher than expected. c1.medium is another freak, at 800 MBit/s.

I gathered this by combing dozens of sources doing benchmarks (primarily using iPerf & TCP connections). Credit to CloudHarmony & flux7 in particular for many of the benchmarks (note that those two links go to google searches showing the numerous individual benchmarks).

Caveats & Notes:

The large instance size has the most variation reported:

• m1.large is ~800 Mbit/s (!!!)
• t2.large = ~500 MBit/s
• c3.large = ~500-570 Mbit/s (different results from different sources)
• c4.large = ~520 MBit/s (I've confirmed this independently, by the way)
• m3.large is better at ~700 MBit/s
• m4.large is ~445 Mbit/s
• r3.large is ~390 Mbit/s

Burstable (T2) instances appear to exhibit burstable networking performance too:

• The CloudHarmony iperf benchmarks show initial transfers start at 1 GBit/s and then gradually drop to the sustained levels above after a few minutes. PDF links to reports below:

• t2.small (PDF)

• t2.medium (PDF)
• t2.large (PDF)

Note that these are within the same region - if you're transferring across regions, real performance may be much slower. Even for the larger instances, I'm seeing numbers of a few hundred MBit/s.

In SQLite this is simpler. I think there are similar implementations for MySQL, MSSql and Orable

CREATE TABLE Beatles (id integer, name string );
INSERT INTO Beatles VALUES (1, "Paul");
INSERT INTO Beatles VALUES (2, "John");
INSERT INTO Beatles VALUES (3, "Ringo");
INSERT INTO Beatles VALUES (4, "George");
SELECT GROUP_CONCAT(name, ',') FROM Beatles;

Maybe this will work:

public class Array {

    int data[] = new int[10]; 
    /* Creates a new instance of Array */
    public Array() {
        data= {10,20,30,40,50,60,71,80,90,91};
    }
}

You can't do this reliably with the keyup event. If you want to know something about the character that was typed, you have to use the keypress event instead.

The following example will work all the time in most browsers but there are some edge cases that you should be aware of. For what is in my view the definitive guide on this, see http://unixpapa.com/js/key.html.

$("input").keypress(function(e) {
    if (e.which !== 0) {
        alert("Charcter was typed. It was: " + String.fromCharCode(e.which));
    }
});

keyup and keydown give you information about the physical key that was pressed. On standard US/UK keyboards in their standard layouts, it looks like there is a correlation between the keyCode property of these events and the character they represent. However, this is not reliable: different keyboard layouts will have different mappings.

1. Is it really a .ico, or is it just named ".ico"?
2. What browser are you testing in?

The absolutely easiest way to have a favicon is to place an icon called "favicon.ico" in the root folder. That just works everywhere, no code needed at all.

If you must have it in a subdirectory, use:

<link rel="shortcut icon" href="/img/favicon.ico" />

Note the / before img to ensure it is anchored to the root folder.

To answer the original question: yes, you can access the index value of a row in apply(). It is available under the key name and requires that you specify axis=1 (because the lambda processes the columns of a row and not the rows of a column).

Working example (pandas 0.23.4):

>>> import pandas as pd
>>> df = pd.DataFrame([[1,2,3],[4,5,6]], columns=['a','b','c'])
>>> df.set_index('a', inplace=True)
>>> df
   b  c
a      
1  2  3
4  5  6
>>> df['index_x10'] = df.apply(lambda row: 10*row.name, axis=1)
>>> df
   b  c  index_x10
a                 
1  2  3         10
4  5  6         40

What about using reduce(callback[, initialValue]) method of JavaScript 1.8

list.reduce((p,n) => p.concat(n),[]);

Would do the job.

I had problem too. I switced Port but couldn't start on 8012.

Skype was involved becouse it had the same port - 80. And it couldn't let apache change it's port.

So just restart computer and Before turning on any other programs Open xampp first change port let's say from 80 to 8000 or 8012 on these lines in httpd.conf

Listen 80
ServerName localhost:80

Restart xampp, Start apache, check localhost.

A workaround is to use a willAnswer() method.

For example the following works (and doesn't throw a MockitoException but actually throws a checked Exception as required here) using BDDMockito:

given(someObj.someMethod(stringArg1)).willAnswer( invocation -> { throw new Exception("abc msg"); });

The equivalent for plain Mockito would to use the doAnswer method

I am using NodeJS on windows 10. I used process.env.var-name to access the variables but failed because it gives me windows path variables as a JSON object, so I installed dotenv ( npm install dotenv ). dotenv gets process envirnoment variables from your project's .evn file

1. npm install dotenv or yarn add dotenv

2. const dotenv = require('dotenv'); dotenv.config();

3. process.env.variable_name

1. output
