This warning comes when you don't add a key to your list items.As per react js Docs -

Keys help React identify which items have changed, are added, or are removed. Keys should be given to the elements inside the array to give the elements a stable identity:

const numbers = [1, 2, 3, 4, 5];
const listItems = numbers.map((number) =>
  <li key={number.toString()}>
    {number}
  </li>
);

The best way to pick a key is to use a string that uniquely identifies a list item among its siblings. Most often you would use IDs from your data as keys:

const todoItems = todos.map((todo) =>
  <li key={todo.id}>
    {todo.text}
  </li>
);

When you don’t have stable IDs for rendered items, you may use the item index as a key as a last resort

const todoItems = todos.map((todo, index) =>
  // Only do this if items have no stable IDs
  <li key={index}>
    {todo.text}
  </li>
);

One of the way you can use it

When you are using the Functional component then follow the instruction here.

• add a variable in your component
• create an event change browser URL change/or other change
• re-assign the current path (URL)
• use javascript match function and set active or others

Use the above code here.

import React, { useEffect } from 'react';
import { Link } from 'react-router-dom';

const NavItems = () => {
    let pathname = window.location.pathname;
    useEffect(() => {
        pathname = window.location.pathname;
    }, [window.location.pathname]);

    return (
        <>
            <li className="px-4">
                <Link to="/home" className={`${pathname.match('/home') ? 'link-active' : ''}`}>Home</Link>
            </li>
            <li className="px-4">
                <Link to="/about-me" className={`${pathname.match('/about-me') ? 'link-active' : ''}`}>About-me</Link>
            </li>
            <li className="px-4">
                <Link to="/skill" className={`${pathname.match('/skill') ? 'link-active' : ''}`}>Skill</Link>
            </li>
            <li className="px-4">
                <Link to="/protfolio" className={`${pathname.match('/protfolio') ? 'link-active' : ''}`}>Protfolio</Link>
            </li>
            <li className="pl-4">
                <Link to="/contact" className={`${pathname.match('/contact') ? 'link-active' : ''}`}>Contact</Link>
            </li>
        </>
    );
}

export default NavItems;

My case, the server was encrypting with padding disabled. But the client was trying to decrypt with the padding enabled.

While using EVP_CIPHER*, by default the padding is enabled. To disable explicitly we need to do

EVP_CIPHER_CTX_set_padding(context, 0);

So non matching padding options can be one reason.

I had the same issue with a site which previously was running fine. I resolved the issue by deleting the temporary files from C:\WINDOWS\Microsoft.NET\Framework\v#.#.#####\Temporary ASP.NET Files\@projectName\###CC##C\###C#CC

Please remove . from your target it should be a id

<a href="#bannerformmodal" data-toggle="modal" data-target="#bannerformmodal">Load me</a>

Also you have to give your modal id like below

<div class="modal fade bannerformmodal" tabindex="-1" role="dialog" aria-labelledby="bannerformmodal" aria-hidden="true" id="bannerformmodal">

Here is the solution in a fiddle.

A SOAP request is an XML file consisting of the parameters you are sending to the server.

The SOAP response is equally an XML file, but now with everything the service wants to give you.

Basically the WSDL is a XML file that explains the structure of those two XML.

To implement simple SOAP clients in Java, you can use the SAAJ framework (it is shipped with JSE 1.6 and above):

SOAP with Attachments API for Java (SAAJ) is mainly used for dealing directly with SOAP Request/Response messages which happens behind the scenes in any Web Service API. It allows the developers to directly send and receive soap messages instead of using JAX-WS.

See below a working example (run it!) of a SOAP web service call using SAAJ. It calls this web service.

import javax.xml.soap.*;

public class SOAPClientSAAJ {

    // SAAJ - SOAP Client Testing
    public static void main(String args[]) {
        /*
            The example below requests from the Web Service at:
             http://www.webservicex.net/uszip.asmx?op=GetInfoByCity


            To call other WS, change the parameters below, which are:
             - the SOAP Endpoint URL (that is, where the service is responding from)
             - the SOAP Action

            Also change the contents of the method createSoapEnvelope() in this class. It constructs
             the inner part of the SOAP envelope that is actually sent.
         */
        String soapEndpointUrl = "http://www.webservicex.net/uszip.asmx";
        String soapAction = "http://www.webserviceX.NET/GetInfoByCity";

        callSoapWebService(soapEndpointUrl, soapAction);
    }

    private static void createSoapEnvelope(SOAPMessage soapMessage) throws SOAPException {
        SOAPPart soapPart = soapMessage.getSOAPPart();

        String myNamespace = "myNamespace";
        String myNamespaceURI = "http://www.webserviceX.NET";

        // SOAP Envelope
        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration(myNamespace, myNamespaceURI);

            /*
            Constructed SOAP Request Message:
            <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:myNamespace="http://www.webserviceX.NET">
                <SOAP-ENV:Header/>

                    <myNamespace:GetInfoByCity>
                        <myNamespace:USCity>New York</myNamespace:USCity>
                    </myNamespace:GetInfoByCity>
                </SOAP-ENV:Body>
            </SOAP-ENV:Envelope>
            */

        // SOAP Body
        SOAPBody soapBody = envelope.getBody();
        SOAPElement soapBodyElem = soapBody.addChildElement("GetInfoByCity", myNamespace);
        SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("USCity", myNamespace);
        soapBodyElem1.addTextNode("New York");
    }

    private static void callSoapWebService(String soapEndpointUrl, String soapAction) {
        try {
            // Create SOAP Connection
            SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
            SOAPConnection soapConnection = soapConnectionFactory.createConnection();

            // Send SOAP Message to SOAP Server
            SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(soapAction), soapEndpointUrl);

            // Print the SOAP Response
            System.out.println("Response SOAP Message:");
            soapResponse.writeTo(System.out);
            System.out.println();

            soapConnection.close();
        } catch (Exception e) {
            System.err.println("\nError occurred while sending SOAP Request to Server!\nMake sure you have the correct endpoint URL and SOAPAction!\n");
            e.printStackTrace();
        }
    }

    private static SOAPMessage createSOAPRequest(String soapAction) throws Exception {
        MessageFactory messageFactory = MessageFactory.newInstance();
        SOAPMessage soapMessage = messageFactory.createMessage();

        createSoapEnvelope(soapMessage);

        MimeHeaders headers = soapMessage.getMimeHeaders();
        headers.addHeader("SOAPAction", soapAction);

        soapMessage.saveChanges();

        /* Print the request message, just for debugging purposes */
        System.out.println("Request SOAP Message:");
        soapMessage.writeTo(System.out);
        System.out.println("\n");

        return soapMessage;

}

make sure the name of the folder that contains the font name is "fonts" not "font"

First off, you have to specify you wish to use Document Literal style:

$client = new SoapClient(NULL, array(
    'location' => 'https://example.com/path/to/service',
    'uri' => 'http://example.com/wsdl',
    'trace' => 1,
    'use' => SOAP_LITERAL)
);

Then, you need to transform your data into a SoapVar; I've written a simple transform function:

function soapify(array $data)
{
        foreach ($data as &$value) {
                if (is_array($value)) {
                        $value = soapify($value);
                }
        }

        return new SoapVar($data, SOAP_ENC_OBJECT);
}

Then, you apply this transform function onto your data:

$data = soapify(array(
    'Acquirer' => array(
        'Id' => 'MyId',
        'UserId' => 'MyUserId',
        'Password' => 'MyPassword',
    ),
));

Finally, you call the service passing the Data parameter:

$method = 'Echo';

$result = $client->$method(new SoapParam($data, 'Data'));

We can consider a telephone call In that Number is wsdl and exchange of information is soap.

WSDL is description how to connect with communication server.SOAP is have communication messages.

Like KingCronus mentioned in the comments you can use the row class to make the list or heading on its own line. You could use the row class on either or both elements:

<ul class="nav nav-tabs span2 row">
  <li><a href="./index.html"><i class="icon-black icon-music"></i></a></li>
  <li><a href="./about.html"><i class="icon-black icon-eye-open"></i></a></li>
  <li><a href="./team.html"><i class="icon-black icon-user"></i></a></li>
  <li><a href="./contact.html"><i class="icon-black icon-envelope"></i></a></li>
</ul>

<div class="well span6 row">
  <h3>I wish this appeared on the next line without having to gratuitously use BR!</h3>
</div>

Thanks,Bruno for giving me heads up on Common Name and Subject Alternative Name. As we figured out certificate was generated with CN with DNS name of network and asked for regeneration of new certificate with Subject Alternative Name entry i.e. san=ip:10.0.0.1. which is the actual solution.

But, we managed to find out a workaround with which we can able to run on development phase. Just add a static block in the class from which we are making ssl connection.

static {
    HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier()
        {
            public boolean verify(String hostname, SSLSession session)
            {
                // ip address of the service URL(like.23.28.244.244)
                if (hostname.equals("23.28.244.244"))
                    return true;
                return false;
            }
        });
}

If you happen to be using Java 8, there is a much slicker way of achieving the same result:

static {
    HttpsURLConnection.setDefaultHostnameVerifier((hostname, session) -> hostname.equals("127.0.0.1"));
}

Try this code:

EndpointImpl impl = (EndpointImpl)Endpoint.publish(address, implementor);
    impl.getServer().getEndpoint().getInInterceptors().add(new LoggingInInterceptor());
    impl.getServer().getEndpoint().getOutInterceptors().add(new LoggingOutInterceptor());

Inside the logback.xml you need to put the interface name for webservice:

        class="com.progressoft.ecc.integration.logging.ThreadNameDiscriminator">

If you are still recieving the InvalidKeyException when running my AES encryption program with 256 bit keys, but not with 128 bit keys, it is because you have not installed the new policy JAR files correctly, and has nothing to do with BouncyCastle (which is also restrained by those policy files). Try uninstalling, then re-installing java and then replaceing the old jar's with the new unlimited strength ones. Other than that, I'm out of ideas, best of luck.

You can see the policy files themselves if you open up the lib/security/local_policy.jar and US_export_policy.jar files in winzip and look at the conatined *.policy files in notepad and make sure they look like this:

default_local.policy:

    // Country-specific policy file for countries with no limits on crypto strength.
grant {
    // There is no restriction to any algorithms.
    permission javax.crypto.CryptoAllPermission; 
};

default_US_export.policy:

// Manufacturing policy file.
grant {
    // There is no restriction to any algorithms.
    permission javax.crypto.CryptoAllPermission; 
};

try removing the extra '/' after the operation name (authentication) when invoking through the client

/axis2/services/MyService/authentication?username=Denise345&password=xxxxx

Either encode the needed XML entities or use CDATA.

<arg0>
    <!--Optional:-->
    <parameter1>&lt;test>like this&lt;/test></parameter1>
    <!--Optional:-->
    <parameter2><![CDATA[<test>or like this</test>]]></parameter2>
 </arg0>

The urls are different.

• http://localhost/AccountSvc/DataInquiry.asmx

vs.

• /acctinqsvc/portfolioinquiry.asmx

Resolve this issue first, as if the web server cannot resolve the URL you are attempting to POST to, you won't even begin to process the actions described by your request.

You should only need to create the WebRequest to the ASMX root URL, ie: http://localhost/AccountSvc/DataInquiry.asmx, and specify the desired method/operation in the SOAPAction header.

The SOAPAction header values are different.

• http://localhost/AccountSvc/DataInquiry.asmx/ + methodName

vs.

• http://tempuri.org/GetMyName

You should be able to determine the correct SOAPAction by going to the correct ASMX URL and appending ?wsdl

There should be a <soap:operation> tag underneath the <wsdl:operation> tag that matches the operation you are attempting to execute, which appears to be GetMyName.

There is no XML declaration in the request body that includes your SOAP XML.

You specify text/xml in the ContentType of your HttpRequest and no charset. Perhaps these default to us-ascii, but there's no telling if you aren't specifying them!

The SoapUI created XML includes an XML declaration that specifies an encoding of utf-8, which also matches the Content-Type provided to the HTTP request which is: text/xml; charset=utf-8

Hope that helps!

I had the same problem (and solved it) while trying to parse an XML document with freemarker.

I had no spaces before the header of XML file.

The problem occurs when and only when the file encoding and the XML encoding attribute are different. (ex: UTF-8 file with UTF-16 attribute in header).

So I had two ways of solving the problem:

1. changing the encoding of the file itself
2. changing the header UTF-16 to UTF-8

Easiest: http://www.addthis.com/

Best? Well. probably not, But If you don't want to design something bespoke this is the best there is...

I faced the same issue. Our application running on four application servers and due to invalid schema location mentioned on one of the web service WSDL, hung threads are generated on the servers . The appliucations got down frequently. After corrected the schema Location , the issue got resolved.

why don't u try using an absolute xPath

//soap:Envelope[1]/soap:Body[1]/PaymentNotification[1]/payment

or since u know that it is a payment and payment doesn't have any attributes just select directly from payment

//soap:Envelope[1]/soap:Body[1]/PaymentNotification[1]/payment/*

The Hash Password Support and Token Assertion Parameters in Metro 1.2 explains very nicely what a UsernameToken with Digest Password looks like:

Digest Password Support

The WSS 1.1 Username Token Profile allows digest passwords to be sent in a wsse:UsernameToken of a SOAP message. Two more optional elements are included in the wsse:UsernameToken in this case: wsse:Nonce and wsse:Created. A nonce is a random value that the sender creates to include in each UsernameToken that it sends. A creation time is added to combine nonces to a "freshness" time period. The Password Digest in this case is calculated as:

Password_Digest = Base64 ( SHA-1 ( nonce + created + password ) )

This is how a UsernameToken with Digest Password looks like:

<wsse:UsernameToken wsu:Id="uuid_faf0159a-6b13-4139-a6da-cb7b4100c10c">
   <wsse:Username>Alice</wsse:Username>
   <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">6S3P2EWNP3lQf+9VC3emNoT57oQ=</wsse:Password>
   <wsse:Nonce EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">YF6j8V/CAqi+1nRsGLRbuZhi</wsse:Nonce>
   <wsu:Created>2008-04-28T10:02:11Z</wsu:Created>
</wsse:UsernameToken>

We put together Web Services on Windows Server and were trying to connect with PHP on Apache. We got the same error. The issue ended up being different versions of the Soap client on the different servers. Matching the SOAP versions in the options on both servers solved the issue in our case.

The documentation could help you : http://java.sun.com/j2se/1.5.0/docs/api/javax/xml/parsers/DocumentBuilder.html

The method DocumentBuilder.parse(String) takes a URI and tries to open it. If you want to directly give the content, you have to give it an InputStream or Reader, for example a StringReader. ... Welcome to the Java standard levels of indirections !

Basically :

DocumentBuilder db = ...;
String xml = ...;
db.parse(new InputSource(new StringReader(xml)));

Note that if you read your XML from a file, you can directly give the File object to DocumentBuilder.parse() .

As a side note, this is a pattern you will encounter a lot in Java. Usually, most API work with Streams more than with Strings. Using Streams means that potentially not all the content has to be loaded in memory at the same time, which can be a great idea !

You should grab a copy of Erica Sadun's mdhelper command line utility (OS X binary & source). It supports listing and extracting the contents of iPhone/iPod Touch backups, including address book & SMS databases, and other application metadata and settings.

It looks like not a ie bug, just for diffrent understanding to the css standard. If outside container is not specified the z-index, but the inner element specified a higher z-index. So the container's sibling maybe overlay the high z-index element. Even if like that, it only occurs in IE7, but IE6, IE8 and Firefox is ok.

for those who got here because the title of the question:

I use Reply-To: address with webforms. when someone fills out the form, the webpage sends an automatic email to the page's owner. the From: is the automatic mail sender's address, so the owner knows it is from the webform. but the Reply-To: address is the one filled in in the form by the user, so the owner can just hit reply to contact them.

It's very simple. You are getting the result into an Object which is a primitive one.

Your code:

Object result = (Object)envelope.getResponse();

Correct code:

SoapObject result=(SoapObject)envelope.getResponse();

//To get the data.
String resultData=result.getProperty(0).toString();
// 0 is the first object of data.

I think this should definitely work.

Tips and tricks

less

Why are you using editors to just look at a (large) file?

Under *nix or Cygwin, just use less. (There is a famous saying – "less is more, more or less" – because "less" replaced the earlier Unix command "more", with the addition that you could scroll back up.) Searching and navigating under less is very similar to Vim, but there is no swap file and little RAM used.

There is a Win32 port of GNU less. See the "less" section of the answer above.

Perl

Perl is good for quick scripts, and its .. (range flip-flop) operator makes for a nice selection mechanism to limit the crud you have to wade through.

For example:

$ perl -n -e 'print if ( 1000000 .. 2000000)' humongo.txt | less

This will extract everything from line 1 million to line 2 million, and allow you to sift the output manually in less.

Another example:

$ perl -n -e 'print if ( /regex one/ .. /regex two/)' humongo.txt | less

This starts printing when the "regular expression one" finds something, and stops when the "regular expression two" find the end of an interesting block. It may find multiple blocks. Sift the output...

logparser

This is another useful tool you can use. To quote the Wikipedia article:

logparser is a flexible command line utility that was initially written by Gabriele Giuseppini, a Microsoft employee, to automate tests for IIS logging. It was intended for use with the Windows operating system, and was included with the IIS 6.0 Resource Kit Tools. The default behavior of logparser works like a "data processing pipeline", by taking an SQL expression on the command line, and outputting the lines containing matches for the SQL expression.

Microsoft describes Logparser as a powerful, versatile tool that provides universal query access to text-based data such as log files, XML files and CSV files, as well as key data sources on the Windows operating system such as the Event Log, the Registry, the file system, and Active Directory. The results of the input query can be custom-formatted in text based output, or they can be persisted to more specialty targets like SQL, SYSLOG, or a chart.

Example usage:

C:\>logparser.exe -i:textline -o:tsv "select Index, Text from 'c:\path\to\file.log' where line > 1000 and line < 2000"
C:\>logparser.exe -i:textline -o:tsv "select Index, Text from 'c:\path\to\file.log' where line like '%pattern%'"

The relativity of sizes

100 MB isn't too big. 3 GB is getting kind of big. I used to work at a print & mail facility that created about 2% of U.S. first class mail. One of the systems for which I was the tech lead accounted for about 15+% of the pieces of mail. We had some big files to debug here and there.

And more...

Feel free to add more tools and information here. This answer is community wiki for a reason! We all need more advice on dealing with large amounts of data...

There is one more important difference between a HashTable and Dictionary. If you use indexers to get a value out of a HashTable, the HashTable will successfully return null for a non-existent item, whereas the Dictionary will throw an error if you try accessing a item using a indexer which does not exist in the Dictionary

How big is m?

You could do something like:

create table two select null foo union all select null;
create temporary table seq ( foo int primary key auto_increment ) auto_increment=9 select a.foo from two a, two b, two c, two d;
select * from seq where foo <= 23;

where the auto_increment is set to n and the where clause compares to m and the number of times the two table is repeated is at least ceil(log(m-n+1)/log(2)).

(The non-temporary two table could be omitted by replacing two with (select null foo union all select null) in the create temporary table seq.)

If you have sequences of multiple blank lines in a row, and would like only one blank line per sequence, try

grep -v "unwantedThing" foo.txt | cat -s

cat -s suppresses repeated empty output lines.

Your output would go from

match1



match2

to

match1

match2

The three blank lines in the original output would be compressed or "squeezed" into one blank line.

To check whether the frame have been loaded, use onload function. Or put your main function in load: I recommend to use load when creating the iframe by js

 $('<iframe />', {
   src: url,
   id:  'receiver',
   frameborder: 1,
   load:function(){
     //put your code here, so that those code can be make sure to be run after the frame loaded
   }
   }).appendTo('body');

If it is something to do with the data in your database, why not utilize database isolation locking to achieve?

Hanselman has a post on using the WinFormsApplicationBase class from the Microsoft.VisualBasic assembly to do this.

The easiest way is to use date, which lets you mix hard-coded values with ones extracted from a timestamp. If you don't give a timestamp, it assumes the current date and time.

// Current timestamp is assumed, so these find first and last day of THIS month
$first_day_this_month = date('m-01-Y'); // hard-coded '01' for first day
$last_day_this_month  = date('m-t-Y');

// With timestamp, this gets last day of April 2010
$last_day_april_2010 = date('m-t-Y', strtotime('April 21, 2010'));

date() searches the string it's given, like 'm-t-Y', for specific symbols, and it replaces them with values from its timestamp. So we can use those symbols to extract the values and formatting that we want from the timestamp. In the examples above:

• Y gives you the 4-digit year from the timestamp ('2010')
• m gives you the numeric month from the timestamp, with a leading zero ('04')
• t gives you the number of days in the timestamp's month ('30')

You can be creative with this. For example, to get the first and last second of a month:

$timestamp    = strtotime('February 2012');
$first_second = date('m-01-Y 00:00:00', $timestamp);
$last_second  = date('m-t-Y 12:59:59', $timestamp); // A leap year!

See http://php.net/manual/en/function.date.php for other symbols and more details.

Pidfile contains pid of a process. It is a convention allowing long running processes to be more self-aware. Server process can inspect it to stop itself, or have heuristic that its other instance is already running. Pidfiles can also be used to conventiently kill risk manually, e.g. pkill -F <some.pid>

For input field validation you can do:

<input ng-model="discount" type="number" ng-attr-max="{{discountType == '%' ? 100 : undefined}}">

This will apply the attribute max to 100 only if discountType is defined as %

Using SQL Developer Version 4.0.2.15 Build 15.21 the following works:

SET SERVEROUTPUT ON
var InParam1 varchar2(100)
var InParam2 varchar2(100)
var InParam3 varchar2(100)
var OutParam1 varchar2(100)

BEGIN
    /* Assign values to IN parameters */
    :InParam1 := 'one';
    :InParam2 := 'two';
    :InParam3 := 'three';

    /* Call procedure within package, identifying schema if necessary */
    schema.package.procedure(:InParam1, :InParam2, :InParam3, :OutParam1);
    dbms_output.enable;
    dbms_output.put_line('OutParam1: ' || :OutParam1);
END;
/

1. click on three dots in the top right ->
2. click on "Undock into separate window" icon

We can also try this solution

ApplicationContext ctx = new ClassPathXmlApplicationContext("classpath*:app-context.xml");

in this the spring automatically finds the class in the class path itself

You can use the pathinfo() function built into PHP for that:

$info = pathinfo(storage_path().'/uploads/categories/featured_image.jpg');
$ext = $info['extension'];

Or more concisely, you can pass an option get get it directly;

$ext = pathinfo(storage_path().'/uploads/categories/featured_image.jpg', PATHINFO_EXTENSION);

Put the video inside a parent div, and set all to 100% width & height with fill of cover. This will ensure the video isn't distorted and ALWAYS fills the div entirely.

.video-wrapper {
    width: 100%;
    height: 100%;
}

.video-wrapper video {
    object-fit: cover;
    width: 100%;
    height: 100%;
}

When you use routerLink like this, then you need to pass the value of the route it should go to. But when you use routerLink with the property binding syntax, like this: [routerLink], then it should be assigned a name of the property the value of which will be the route it should navigate the user to.

So to fix your issue, replace this routerLink="['/about']" with routerLink="/about" in your HTML.

There were other places where you used property binding syntax when it wasn't really required. I've fixed it and you can simply use the template syntax below:

<nav class="main-nav>
  <ul 
    class="main-nav__list" 
    ng-sticky 
    addClass="main-sticky-link" 
    [ngClass]="ref.click ? 'Navbar__ToggleShow' : ''">
    <li class="main-nav__item" routerLinkActive="active">
      <a class="main-nav__link" routerLink="/">Home</a>
    </li>
    <li class="main-nav__item" routerLinkActive="active"> 
      <a class="main-nav__link" routerLink="/about">About us</a>
    </li>
  </ul>
</nav>

It also needs to know where exactly should it load the template for the Component corresponding to the route it has reached. So for that, don't forget to add a <router-outlet></router-outlet>, either in your template provided above or in a parent component.

There's another issue with your AppRoutingModule. You need to export the RouterModule from there so that it is available to your AppModule when it imports it. To fix that, export it from your AppRoutingModule by adding it to the exports array.

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';
import { MainLayoutComponent } from './layout/main-layout/main-layout.component';
import { AboutComponent } from './components/about/about.component';
import { WhatwedoComponent } from './components/whatwedo/whatwedo.component';
import { FooterComponent } from './components/footer/footer.component';
import { ProjectsComponent } from './components/projects/projects.component';
const routes: Routes = [
  { path: 'about', component: AboutComponent },
  { path: 'what', component: WhatwedoComponent },
  { path: 'contacts', component: FooterComponent },
  { path: 'projects', component: ProjectsComponent},
];

@NgModule({
  imports: [
    CommonModule,
    RouterModule.forRoot(routes),
  ],
  exports: [RouterModule],
  declarations: []
})
export class AppRoutingModule { }

You are mixing tabs and spaces. Don't do that. Specifically, the __init__ function body is indented with tabs while your on_data method is not.

Here is a screenshot of your code in my text editor; I set the tab stop to 8 spaces (which is what Python uses) and selected the text, which causes the editor to display tabs with continuous horizontal lines:

You have your editor set to expanding tabs to every fourth column instead, so the methods appear to line up.

Run your code with:

python -tt scriptname.py

and fix all errors that finds. Then configure your editor to use spaces only for indentation; a good editor will insert 4 spaces every time you use the TAB key.

If your just interested in sharing complex data types between javascript and python, check out jsonpickle. It wraps the standard Python JSON libraries, but has some smarts in serializing and deserializing Python classes and other data types.

Quite a few Google App Engine projects have used this library. Joose and FirePython both incorporate jsonpickle.

Sometimes the interest is in knowing the number of messages in each partition, for example, when testing a custom partitioner.The ensuing steps have been tested to work with Kafka 0.10.2.1-2 from Confluent 3.2. Given a Kafka topic, kt and the following command-line:

$ kafka-run-class kafka.tools.GetOffsetShell \
  --broker-list host01:9092,host02:9092,host02:9092 --topic kt

That prints the sample output showing the count of messages in the three partitions:

kt:2:6138
kt:1:6123
kt:0:6137

The number of lines could be more or less depending on the number of partitions for the topic.

The FileNameExtensionFilter class is intended for Swing to be used in a JFileChooser.

Try using a FilenameFilter instead. For example:

File dir = new File("/users/blah/dirname");
File[] files = dir.listFiles(new FilenameFilter() {
    public boolean accept(File dir, String name) {
        return name.toLowerCase().endsWith(".txt");
    }
});

The best way to get good control over the colorbar position is to give it its own axis. Like so:

# What I imagine your plotting looks like so far
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax1.plot(your_data)

# Now adding the colorbar
cbaxes = fig.add_axes([0.8, 0.1, 0.03, 0.8]) 
cb = plt.colorbar(ax1, cax = cbaxes)  

The numbers in the square brackets of add_axes refer to [left, bottom, width, height], where the coordinates are just fractions that go from 0 to 1 of the plotting area.

emacs works very well with files into the 100's of megabytes, I've used it on log files without too much trouble.

But generally when I have some kind of analysis task, I find writing a perl script a better choice.

Using the code from my answer to a very similar question:

Sub DoSomething()
Dim Mainfram(4) As String
Dim cell As Excel.Range

Mainfram(0) = "apple"
Mainfram(1) = "pear"
Mainfram(2) = "orange"
Mainfram(3) = "fruit"

For Each cell In Selection
  If IsInArray(cell.Value, MainFram) Then
    Row(cell.Row).Style = "Accent1"
  End If
Next cell

End Sub

Function IsInArray(stringToBeFound As String, arr As Variant) As Boolean
  IsInArray = (UBound(Filter(arr, stringToBeFound)) > -1)
End Function

In this specific case (mod 7), we still can replace %7 with bitwise operators:

// Return X%7 for X >= 0.
int mod7(int x)
{
  while (x > 7) x = (x&7) + (x>>3);
  return (x == 7)?0:x;
}

It works because 8%7 = 1. Obviously, this code is probably less efficient than a simple x%7, and certainly less readable.

What programming languages can one use to develop iPhone, iPod Touch and iPad (iOs) applications?

Ruby, Python, Lua, Scheme, Lisp, Smalltalk, C#, Haskell, ActionScript, JavaScript, Objective-C, C++, C. That's just the ones that pop into my head right now. I'm sure there's hundreds if not thousands of others. (E.g. there's no reason why you couldn't use any .NET language with MonoTouch, i.e. VB.NET, F#, Nemerle, Boo, Cobra, ...)

Also are there plans in the future to expand the amount of programming languages that iOs will support?

Sure. Pretty much every programming language community on this planet is currently working on getting their language to run on iOS.

Also, a lot of people are working on programming languages specifically designed for touch devices such as iPod touch, iPhone and iPad, e.g. Phil Mercurio's Thyrd language.

The most readable CSS-only solution would probably be to use the aria-expanded attribute. Remember that you'll need to add aria-expanded="false" to all collapse-elements as this is not set on load (only on first click).

The HTML:

<h2 data-toggle="collapse" href="#collapseId" aria-expanded="false">
    <span class="glyphicon glyphicon-chevron-right"></span>
    <span class="glyphicon glyphicon-chevron-down"></span> Title
</h2>

The CSS:

h2[aria-expanded="false"] span.glyphicon-chevron-down,
h2[aria-expanded="true"] span.glyphicon-chevron-right
{
    display: none;
}

h2[aria-expanded="true"] span.glyphicon-chevron-down,
h2[aria-expanded="false"] span.glyphicon-chevron-right
{
    display: inline;
}

Works with Bootstrap 3.x.

In addition to the solutions posted above, having gone through the exact same problem, make sure you check your HTML. More specifically whether you've properly labelled your elements, as well as class and id selectors. You can do this either manually or through a validator (https://validator.w3.org/).

For me, I missed the equal sign next to the class (<div class someDiv> vs <div class = "someDiv">, hence why no CSS property was applied.

If you are using jQuery you can do this:

$(function() {_x000D_
_x000D_
  var $list = $("#list");_x000D_
_x000D_
  $list.children().detach().sort(function(a, b) {_x000D_
    return $(a).text().localeCompare($(b).text());_x000D_
  }).appendTo($list);_x000D_
_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
_x000D_
<ul id="list">_x000D_
  <li>delta</li>_x000D_
  <li>cat</li>_x000D_
  <li>alpha</li>_x000D_
  <li>cat</li>_x000D_
  <li>beta</li>_x000D_
  <li>gamma</li>_x000D_
  <li>gamma</li>_x000D_
  <li>alpha</li>_x000D_
  <li>cat</li>_x000D_
  <li>delta</li>_x000D_
  <li>bat</li>_x000D_
  <li>cat</li>_x000D_
</ul>

Note that returning 1 and -1 (or 0 and 1) from the compare function is absolutely wrong.

Since Management Studio 2005 it seems that you can use GO with an int parameter, like:

INSERT INTO mytable DEFAULT VALUES
GO 10

The above will insert 10 rows into mytable. Generally speaking, GO will execute the related sql commands n times.

Besides the powerful options on the "Run Configurations.." on a well configured project you'll see the maven tasks on the Run As as well.

If you uninstall all the files but it still fails, use this line:

sudo rm -rf /Library/Java/JavaVirtualMachines/jdk1.8.0.jdk

The simplest thing you can do is cherry picking a range. It does the same as the rebase --onto but is easier for the eyes :)

git cherry-pick quickfix1..quickfix2

You could use HTML's indeterminate IDL attribute on input elements.

When you are using GET Method the contract must be this.

[WebGet(UriTemplate = "/", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)]
List<User> Get();

with this we have a json without the boot parameter

Aldo Flores @alduar http://alduar.blogspot.com

Use the load event:

img = new Image();

img.onload = function(){
  // image  has been loaded
};

img.src = image_url;

Also have a look at:

• Preloading and the JavaScript Image() object

To display the Json data using Robin Hartman code. You need to add, the below line.

The code he gave gives you Object, object. this code retrieves the data in a better way.

result.innerText =JSON.stringify(data);

You can check Date Mutators: https://laravel.com/docs/5.3/eloquent-mutators#date-mutators

You need set in your User model column from_date in $dates array and then you can change format in $dateFormat

The another option is also put this method to your User model:

public function getFromDateAttribute($value) {
    return \Carbon\Carbon::parse($value)->format('d-m-Y');
}

and then in view if you run {{ $user->from_date }} you will be see format that you want.

For future reference Python is strongly typed. Unlike other dynamic languages, it will not automagically cast objects from one type or the other (say from str to int) so you must do this yourself. You'll like that in the long-run, trust me!

Ideally, the Python script you want to run will be set up with code like this near the end:

def main(arg1, arg2, etc):
    # do whatever the script does


if __name__ == "__main__":
    main(sys.argv[1], sys.argv[2], sys.argv[3])

In other words, if the module is called from the command line, it parses the command line options and then calls another function, main(), to do the actual work. (The actual arguments will vary, and the parsing may be more involved.)

If you want to call such a script from another Python script, however, you can simply import it and call modulename.main() directly, rather than going through the operating system.

os.system will work, but it is the roundabout (read "slow") way to do it, as you are starting a whole new Python interpreter process each time for no raisin.

Try this:

var matches = url.match(/^https?\:\/\/([^\/?#]+)(?:[\/?#]|$)/i);
var domain = matches && matches[1];  // domain will be null if no match is found

If you want to exclude the port from your result, use this expression instead:

/^https?\:\/\/([^\/:?#]+)(?:[\/:?#]|$)/i

Edit: To prevent specific domains from matching, use a negative lookahead. (?!youtube.com)

/^https?\:\/\/(?!(?:www\.)?(?:youtube\.com|youtu\.be))([^\/:?#]+)(?:[\/:?#]|$)/i

Checkout the following article on MSDN about examples of the N format. This is also covered in the Standard Numeric Format Strings article.

Relevant excerpts:

//       Formatting of 1054.32179:
//          N:                     1,054.32 
//          N0:                    1,054 
//          N1:                    1,054.3 
//          N2:                    1,054.32 
//          N3:                    1,054.322 

When precision specifier controls the number of fractional digits in the result string, the result string reflects a number that is rounded to a representable result nearest to the infinitely precise result. If there are two equally near representable results:

• On the .NET Framework and .NET Core up to .NET Core 2.0, the runtime selects the result with the greater least significant digit (that is, using MidpointRounding.AwayFromZero).
• On .NET Core 2.1 and later, the runtime selects the result with an even least significant digit (that is, using MidpointRounding.ToEven).

If you only need the standard functionality of hide only with visibility:hidden to keep the current layout you can use the callback function of hide to alter the css in the tag. Hide docs in jquery

An example :

$('#subs_selection_box').fadeOut('slow', function() {
      $(this).css({"visibility":"hidden"});
      $(this).css({"display":"block"});
});

This will use the normal cool animation to hide the div, but after the animation finish you set the visibility to hidden and display to block.

An example : http://jsfiddle.net/bTkKG/1/

I know you didnt want the $("#aa").css() solution, but you did not specify if it was because using only the css() method you lose the animation.

@mani's Original answer is all you want, but if you'd also like to read it in official way, here's

Reference to Vue's official page:

https://router.vuejs.org/guide/essentials/history-mode.html#caveat

From Spring Documentation:

The @Repository annotation is a marker for any class that fulfils the role or stereotype of a repository (also known as Data Access Object or DAO). Among the uses of this marker is the automatic translation of exceptions, as described in Exception Translation.

Spring provides further stereotype annotations: @Component, @Service, and @Controller. @Component is a generic stereotype for any Spring-managed component. @Repository, @Service, and @Controller are specializations of @Component for more specific use cases (in the persistence, service, and presentation layers, respectively). Therefore, you can annotate your component classes with @Component, but, by annotating them with @Repository, @Service, or @Controller instead, your classes are more properly suited for processing by tools or associating with aspects.

For example, these stereotype annotations make ideal targets for pointcuts. @Repository, @Service, and @Controller can also carry additional semantics in future releases of the Spring Framework. Thus, if you are choosing between using @Component or @Service for your service layer, @Service is clearly the better choice. Similarly, as stated earlier, @Repository is already supported as a marker for automatic exception translation in your persistence layer.

Yes, use getJSONP. It's the only way to make cross domain/server async calls. (*Or it will be in the near future). Something like

$.getJSON('your-api-url/validate.php?'+$(this).serialize+'callback=?', function(data){
if(data)console.log(data);
});

The callback parameter will be filled in automatically by the browser, so don't worry.

On the server side ('validate.php') you would have something like this

<?php
if(isset($_GET))
{
//if condition is met
echo $_GET['callback'] . '(' . "{'message' : 'success', 'userID':'69', 'serial' : 'XYZ99UAUGDVD&orwhatever'}". ')';
}
else echo json_encode(array('error'=>'failed'));
?>

For those who need to figure out simple way

Try getActivity().onBackPressed();

If you're on Windows use the following, select all, and copy from a Notepad window:

notepad ~/.ssh/id_rsa.pub  

If you're on OS X, use:

pbcopy < ~/.ssh/id_rsa.pub

join() is for concatenating all list elements. For concatenating just two strings "+" would make more sense:

strid = repr(595)
print array.array('c', random.sample(string.ascii_letters, 20 - len(strid)))
    .tostring() + strid

If you don't need the user instance on site (as I did), you can do it with

User.objects.filter(pk=userId, groups__name='Editor').exists()

This will produce only one request to the database and return a boolean.

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

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

That returns 1.

Alternatively, you can switch to JRockit which handling permgen differently then sun's jvm. It generally has better performance as well.

In case this might help someone, after installing the thread safe version of PHP 5.5.1, everything was working under apache for my dev sites, but I ran into the same "php5.dll is missing" problem installing Composer using the Composer-Setup.exe - or, as I soon discovered, just running something as simple as php -v from the command line. I made a copy of php5ts.dll and named it php5.dll and everything worked. I assume the Composer installer was specifically looking for "php5.dll" and I knew that the thread safe code would be run by the renamed .dll. I also assume something is wrong with my setup to screw up the command line functionality, but with everything working, I have more important issues to deal with than to try and find the problem.

To create an empty data frame, pass in the number of rows and columns needed into the following function:

create_empty_table <- function(num_rows, num_cols) {
    frame <- data.frame(matrix(NA, nrow = num_rows, ncol = num_cols))
    return(frame)
}

To create an empty frame while specifying the class of each column, simply pass a vector of the desired data types into the following function:

create_empty_table <- function(num_rows, num_cols, type_vec) {
  frame <- data.frame(matrix(NA, nrow = num_rows, ncol = num_cols))
  for(i in 1:ncol(frame)) {
    print(type_vec[i])
    if(type_vec[i] == 'numeric') {frame[,i] <- as.numeric(frame[,i])}
    if(type_vec[i] == 'character') {frame[,i] <- as.character(frame[,i])}
    if(type_vec[i] == 'logical') {frame[,i] <- as.logical(frame[,i])}
    if(type_vec[i] == 'factor') {frame[,i] <- as.factor(frame[,i])}
  }
  return(frame)
}

Use as follows:

df <- create_empty_table(3, 3, c('character','logical','numeric'))

Which gives:

   X1  X2 X3
1 <NA> NA NA
2 <NA> NA NA
3 <NA> NA NA

To confirm your choices, run the following:

lapply(df, class)

#output
$X1

All "normal" triggers in SQL Server are "AFTER ..." triggers. There are no "BEFORE ..." triggers.

JavaScript only has a Number type that stores floating point values.

There is no int.

Edit:

If you want to format the number as a string with two digits after the decimal point use:

(4).toFixed(2)

It turned out that there's a simple, standard way to achieve what I wanted:

import java.net.Authenticator;
import java.net.PasswordAuthentication;

Authenticator myAuth = new Authenticator() 
{
    @Override
    protected PasswordAuthentication getPasswordAuthentication()
    {
        return new PasswordAuthentication("german", "german".toCharArray());
    }
};

Authenticator.setDefault(myAuth);

No custom "sun" classes or external dependencies, and no manually encode anything.

    public static Enum GetRandomEnumValue(this Type t)
    {
        return Enum.GetValues(t)          // get values from Type provided
            .OfType<Enum>()               // casts to Enum
            .OrderBy(e => Guid.NewGuid()) // mess with order of results
            .FirstOrDefault();            // take first item in result
    }
}

public static class Program

    public enum SomeEnum
    {
        One = 1,
        Two = 2,
        Three = 3,

        for(int i=0; i < 10; i++)
        {

You are using jQuery(document).ready(function($) {} means here you are using jQuery instead of $. So to resolve your issue use following code.

jQuery("#submittername").text(submitter_name);

This will resolve your problem.

You can stash your local changes first, then pull, then pop the stash.

git stash
git pull origin master
git stash pop

Anything that overrides changes from remote will have conflicts which you will have to manually resolve.

I was looking to do the same thing, but to preserve the list as a just an array of strings so I wrote a new code, which from what I've been reading may not be the most efficient but worked for what i needed to do:

combineListsAsOne <-function(list1, list2){
  n <- c()
  for(x in list1){
    n<-c(n, x)
  }
  for(y in list2){
    n<-c(n, y)
  }
  return(n)
}

It just creates a new list and adds items from two supplied lists to create one.

Some people say C doesn't have namespaces but that is not technically correct. It has three:

1. Tags (enum, union, and struct)
2. Labels
3. (everything else)

typedef enum { } XYZ; declares an anonymous enumeration and imports it into the global namespace with the name XYZ.

typedef enum ABC { } XYZ; declares an enum named ABC in the tag namespace, then imports it into the global namespace as XYZ.

Some people don't want to bother with the separate namespaces so they typedef everything. Others never typedef because they want the namespacing.

There are two ways to interpret the input data; either -128 is the lowest value, and 127 is the highest (i.e. true signed data), or 0 is the lowest value, 127 is somewhere in the middle, and the next "higher" number is -128, with -1 being the "highest" value (that is, the most significant bit already got misinterpreted as a sign bit in a two's complement notation.

Assuming you mean the latter, the formally correct way is

signed char in = ...
unsigned char out = (in < 0)?(in + 256):in;

which at least gcc properly recognizes as a no-op.

npm outdated will identify packages that should be updated, and npm update <package name> can be used to update each package. But prior to [email protected], npm update <package name> will not update the versions in your package.json which is an issue.

The best workflow is to:

1. Identify out of date packages
2. Update the versions in your package.json
3. Run npm update to install the latest versions of each package

Check out npm-check-updates to help with this workflow.

• Install npm-check-updates
• Run npm-check-updates to list what packages are out of date (basically the same thing as running npm outdated)
• Run npm-check-updates -u to update all the versions in your package.json (this is the magic sauce)
• Run npm update as usual to install the new versions of your packages based on the updated package.json

I had this same problem but only when running spring boot tests cases that required JPA. The end result was that our own jpa test configuration was initializing an EntityManagerFactory and setting the packages to scan. This evidently will override the EntityScan parameters if you are setting it manually.

    final LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
    factory.setJpaVendorAdapter( vendorAdapter );
    factory.setPackagesToScan( Project.class.getPackage().getName());
    factory.setDataSource( dataSource );

Important to note: if you are still stuck you should set a break point in the org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager on the setPackagesToScan() method and take a look at where this is being called and what packages are being passed to it.

"How to attach url link to an image?"

You do it like this:

<a href="http://www.google.com"><img src="http://www.google.com/intl/en_ALL/images/logo.gif"/></a>

See it in action.

You can use the excecl command

int execl(const char *path, const char *arg, ...);

Like shown here

#include <stdio.h>
#include <unistd.h>
#include <dirent.h>

int main (void) {

   return execl ("/bin/pwd", "pwd", NULL);

}

The second argument will be the name of the process as it will appear in the process table.

Alternatively, you can use the getcwd() function to get the current working directory:

#include <stdio.h>
#include <unistd.h>
#include <dirent.h>
#define MAX 255

int main (void) {
char wd[MAX];
wd[MAX-1] = '\0';

if(getcwd(wd, MAX-1) == NULL) {
  printf ("Can not get current working directory\n");
}
else {
  printf("%s\n", wd);
}
  return 0;
}

I have had a similar issue in iOS 8, 9 and 10 and the info above couldn't fix it, however I did discover a solution after a day of working on this. Granted it won't work for everyone but in my case my items were stacked in a column and had 0 height when it should have been content height. Switching the css to be row and wrap fixed the issue. This only works if you have a single item and they are stacked but since it took me a day to find this out I thought I should share my fix!

.wrapper {
    flex-direction: column; // <-- Remove this line
    flex-direction: row; // <-- replace it with
    flex-wrap: wrap; // <-- Add wrapping
}

.item {
    width: 100%;
}

I put this demo with scripts and examples included together:

http://www.mlynn.org/2010/06/mobile-device-detection-and-redirection-with-php/

This example utilizes php functions for user agent detection and offers the additional benefit of permitting users to state a preference for a version of the site which would not typically be the default based on their browser or device type. This is done with cookies (maintained using php on the server-side as opposed to javascript.)

Be sure to check out the download link in the article for the examples.

@OP, you can use for loops to capture the return status of your program, if it outputs something other than numbers

Will result always be the floor of the division?

No. The result varies, but variation happens only for negative values.

What is the defined behavior?

To make it clear floor rounds towards negative infinity,while integer division rounds towards zero (truncates)

For positive values they are the same

int integerDivisionResultPositive= 125/100;//= 1
double flooringResultPositive= floor(125.0/100.0);//=1.0

For negative value this is different

int integerDivisionResultNegative= -125/100;//=-1
double flooringResultNegative= floor(-125.0/100.0);//=-2.0

With Selenium2Library you can use get_source()

s.open_browser("localhost:7080", "firefox")

To create a Twitter share link with a photo, you first need to tweet out the photo from your Twitter account. Once you've tweeted it out, you need to grab the pic.twitter.com link and place that inside your twitter share url.

note: You won't be able to see the pic.twitter.com url so what I do is use a separate account and hit the retweet button. A modal will pop up with the link inside.

You Twitter share link will look something like this:

<a href="https://twitter.com/home?status=This%20photo%20is%20awesome!%20Check%20it%20out:%20pic.twitter.com/9Ee63f7aVp">Share on Twitter</a>

With the following, it is easy to link the Cell address...

As nice as "return by value" might be, it's the kind of code that can lead one into error. Consider the following program:

    #include <string>
    #include <vector>
    #include <iostream>
    using namespace std;
    static std::vector<std::string> strings;
    std::vector<std::string> vecFunc(void) { return strings; };
    int main(int argc, char * argv[]){
      // set up the vector of strings to hold however
      // many strings the user provides on the command line
      for(int idx=1; (idx<argc); ++idx){
         strings.push_back(argv[idx]);
      }

      // now, iterate the strings and print them using the vector function
      // as accessor
      for(std::vector<std::string>::interator idx=vecFunc().begin(); (idx!=vecFunc().end()); ++idx){
         cout << "Addr: " << idx->c_str() << std::endl;
         cout << "Val:  " << *idx << std::endl;
      }
    return 0;
    };

• Q: What will happen when the above is executed? A: A coredump.
• Q: Why didn't the compiler catch the mistake? A: Because the program is syntactically, although not semantically, correct.
• Q: What happens if you modify vecFunc() to return a reference? A: The program runs to completion and produces the expected result.
• Q: What is the difference? A: The compiler does not have to create and manage anonymous objects. The programmer has instructed the compiler to use exactly one object for the iterator and for endpoint determination, rather than two different objects as the broken example does.

The above erroneous program will indicate no errors even if one uses the GNU g++ reporting options -Wall -Wextra -Weffc++

If you must produce a value, then the following would work in place of calling vecFunc() twice:

   std::vector<std::string> lclvec(vecFunc());
   for(std::vector<std::string>::iterator idx=lclvec.begin(); (idx!=lclvec.end()); ++idx)...

The above also produces no anonymous objects during iteration of the loop, but requires a possible copy operation (which, as some note, might be optimized away under some circumstances. But the reference method guarantees that no copy will be produced. Believing the compiler will perform RVO is no substitute for trying to build the most efficient code you can. If you can moot the need for the compiler to do RVO, you are ahead of the game.

I know this is an old question, but victorio also asked if there are any other options to copy data from one table to another. There is a very short and fast way to insert all the records from one table to another (which might or might not have similar design).

If you dont have identity column in table B_table:

INSERT INTO A_db.dbo.A_table
SELECT * FROM B_db.dbo.B_table

If you have identity column in table B_table, you have to specify columns to insert. Basically you select all except identity column, which will be auto incremented by default.

In case if you dont have existing B_table in B_db

SELECT *
INTO B_db.dbo.B_table
FROM A_db.dbo.A_table

will create table B_table in database B_db with all existing values

Use this approach to sum the list of BigDecimal:

List<BigDecimal> values = ... // List of BigDecimal objects
BigDecimal sum = values.stream().reduce((x, y) -> x.add(y)).get();

This approach maps each BigDecimal as a BigDecimal only and reduces them by summing them, which is then returned using the get() method.

Here's another simple way to do the same summing:

List<BigDecimal> values = ... // List of BigDecimal objects
BigDecimal sum = values.stream().reduce(BigDecimal::add).get();

Update

If I were to write the class and lambda expression in the edited question, I would have written it as follows:

import java.math.BigDecimal;
import java.util.LinkedList;

public class Demo
{
  public static void main(String[] args)
  {
    LinkedList<Invoice> invoices = new LinkedList<>();
    invoices.add(new Invoice("C1", "I-001", BigDecimal.valueOf(.1), BigDecimal.valueOf(10)));
    invoices.add(new Invoice("C2", "I-002", BigDecimal.valueOf(.7), BigDecimal.valueOf(13)));
    invoices.add(new Invoice("C3", "I-003", BigDecimal.valueOf(2.3), BigDecimal.valueOf(8)));
    invoices.add(new Invoice("C4", "I-004", BigDecimal.valueOf(1.2), BigDecimal.valueOf(7)));

    // Java 8 approach, using Method Reference for mapping purposes.
    invoices.stream().map(Invoice::total).forEach(System.out::println);
    System.out.println("Sum = " + invoices.stream().map(Invoice::total).reduce((x, y) -> x.add(y)).get());
  }

  // This is just my style of writing classes. Yours can differ.
  static class Invoice
  {
    private String company;
    private String number;
    private BigDecimal unitPrice;
    private BigDecimal quantity;

    public Invoice()
    {
      unitPrice = quantity = BigDecimal.ZERO;
    }

    public Invoice(String company, String number, BigDecimal unitPrice, BigDecimal quantity)
    {
      setCompany(company);
      setNumber(number);
      setUnitPrice(unitPrice);
      setQuantity(quantity);
    }

    public BigDecimal total()
    {
      return unitPrice.multiply(quantity);
    }

    public String getCompany()
    {
      return company;
    }

    public void setCompany(String company)
    {
      this.company = company;
    }

    public String getNumber()
    {
      return number;
    }

    public void setNumber(String number)
    {
      this.number = number;
    }

    public BigDecimal getUnitPrice()
    {
      return unitPrice;
    }

    public void setUnitPrice(BigDecimal unitPrice)
    {
      this.unitPrice = unitPrice;
    }

    public BigDecimal getQuantity()
    {
      return quantity;
    }

    public void setQuantity(BigDecimal quantity)
    {
      this.quantity = quantity;
    }
  }
}

This answer was posted by me in another thread. Hope this helps.

You're probably thinking of the java.util.ArrayList, not the array.

you can use line.seperator for appending new line in

The first option is simply to hide an error with disabling it by configuring errorOnUnhandledRejections in $qProvider configuration as suggested Cengkuru Michael

BUT this will only switch off logging. The error itself will remain

The better solution in this case will be - handling a rejection with .catch(fn) method:

resource.get().$promise
    .then(function (response) {})
    .catch(function (err) {});

LINKS:

• Promise
• Angular:
  • Migrating Angular 1.5 to 1.6
  • $http: remove deprecated callback methods: 'success()/error()'

Construct your method to accept it-

public <T> void printClassNameAndCreateList(Class<T> className){
    //example access 1
    System.out.print(className.getName());

    //example access 2
    ArrayList<T> list = new ArrayList<T>();
    //note that if you create a list this way, you will have to cast input
    list.add((T)nameOfObject);
}

Call the method-

printClassNameAndCreateList(SomeClass.class);

You can also restrict the type of class, for example, this is one of the methods from a library I made-

protected Class postExceptionActivityIn;

protected <T extends PostExceptionActivity>  void  setPostExceptionActivityIn(Class <T> postExceptionActivityIn) {
    this.postExceptionActivityIn = postExceptionActivityIn;
}

You are opening the file as "w", which stands for writable.

Using "w" you won't be able to read the file. Use the following instead:

file = open("File.txt","r")

Additionally, here are the other options:

"r"   Opens a file for reading only.
"r+"  Opens a file for both reading and writing.
"rb"  Opens a file for reading only in binary format.
"rb+" Opens a file for both reading and writing in binary format.
"w"   Opens a file for writing only.
"a"   Open for writing.  The file is created if it does not exist.
"a+"  Open for reading and writing.  The file is created if it does not exist.

If you want to select a value based on true / false use

In the source header you can declare:

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

It is described in the PEP 0263:

Then you can use UTF-8 in strings:

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

u = 'idzie waz waska drózka'
uu = u.decode('utf8')
s = uu.encode('cp1250')
print(s)

This declaration is not needed in Python 3 as UTF-8 is the default source encoding (see PEP 3120).

In addition, it may be worth verifying that your text editor properly encodes your code in UTF-8. Otherwise, you may have invisible characters that are not interpreted as UTF-8.

Server.MapPath specifies the relative or virtual path to map to a physical directory.

• Server.MapPath(".")¹ returns the current physical directory of the file (e.g. aspx) being executed
• Server.MapPath("..") returns the parent directory
• Server.MapPath("~") returns the physical path to the root of the application
• Server.MapPath("/") returns the physical path to the root of the domain name (is not necessarily the same as the root of the application)

An example:

Let's say you pointed a web site application (http://www.example.com/) to

C:\Inetpub\wwwroot

and installed your shop application (sub web as virtual directory in IIS, marked as application) in

D:\WebApps\shop

For example, if you call Server.MapPath() in following request:

http://www.example.com/shop/products/GetProduct.aspx?id=2342

then:

• Server.MapPath(".")¹ returns D:\WebApps\shop\products
• Server.MapPath("..") returns D:\WebApps\shop
• Server.MapPath("~") returns D:\WebApps\shop
• Server.MapPath("/") returns C:\Inetpub\wwwroot
• Server.MapPath("/shop") returns D:\WebApps\shop

If Path starts with either a forward slash (/) or backward slash (\), the MapPath() returns a path as if Path was a full, virtual path.

If Path doesn't start with a slash, the MapPath() returns a path relative to the directory of the request being processed.

Note: in C#, @ is the verbatim literal string operator meaning that the string should be used "as is" and not be processed for escape sequences.

Footnotes

1. Server.MapPath(null) and Server.MapPath("") will produce this effect too.

Summary

You cannot push to the one checked out branch of a repository because it would mess with the user of that repository in a way that will most probably end with loss of data and history. But you can push to any other branch of the same repository.

As bare repositories never have any branch checked out, you can always push to any branch of a bare repository.

There are multiple solutions, depending on your needs.

Solution 1: Use a Bare Repostiory

As suggested, if on one machine, you don't need the working directory, you can move to a bare repository. To avoid messing with the repository, you can just clone it:

machine1$ cd ..
machine1$ mv repo repo.old
machine1$ git clone --bare repo.old repo

Now you can push all you want to the same address as before.

Solution 2: Push to a Non-Checked-Out Branch

But if you need to check out the code on your remote <remote>, then you can use a special branch to push. Let's say that in your local repository you have called your remote origin and you're on branch master. Then you could do

machine2$ git push origin master:master+machine2

Then you need to merge it when you're in the origin remote repo:

machine1$ git merge master+machine2

Autopsy of the Problem

When a branch is checked out, committing will add a new commit with the current branch's head as its parent and move the branch's head to be that new commit.

So

A ? B
    ?
[HEAD,branch1]

becomes

A ? B ? C
        ?
    [HEAD,branch1]

But if someone could push to that branch inbetween, the user would get itself in what git calls detached head mode:

A ? B ? X
    ?   ?
[HEAD] [branch1]

Now the user is not in branch1 anymore, without having explicitly asked to check out another branch. Worse, the user is now outside any branch, and any new commit will just be dangling:

      [HEAD]
        ?
        C
      ?
A ? B ? X
        ?
       [branch1]

Hypothetically, if at this point, the user checks out another branch, then this dangling commit becomes fair game for Git's garbage collector.

I think you're missing your routes, you need to define at least one route for example '/' to index.

e.g.

app.get('/', function (req, res) {
  res.render('index', {});
});

if x is a vector with raw scores then scale(x) is a vector with standardized scores.

Or manually: (x-mean(x))/sd(x)

Your code is working at my end, i have just tested it. Where are you checking your changes? Use Documents directory path. To get path -

NSLog(@"%@",documentsDirectory);

and copy path from console and then open finder and press Cmd+shift+g and paste path here and then open your file

I made a wider input field by using either span4 or span6 as class.

<input type="text" class="span6 input-large search-query">

This way you don't need the additional custom css, mentioned earlier.

ObjectFactory fact = new ObjectFactory();   
JAXBElement<String> str = fact.createCompositeTypeStringValue("vik");    
comp.setStringValue(str);
CompositeType retcomp = service.getDataUsingDataContract(comp);
System.out.println(retcomp.getStringValue().getValue());

I made a small tkinter application which is sets the label after button clicked

#!/usr/bin/env python
from Tkinter import *
from tkFileDialog import askopenfilename
from tkFileDialog import askdirectory


class Application:
    def __init__(self, master):
        frame = Frame(master,width=200,height=200)
        frame.pack()

        self.log_file_btn = Button(frame, text="Select Log File", command=self.selectLogFile,width=25).grid(row=0)
        self.image_folder_btn = Button(frame, text="Select Image Folder", command=self.selectImageFile,width=25).grid(row=1)
        self.quite_button = Button(frame, text="QUIT", fg="red", command=frame.quit,width=25).grid(row=5)

        self.logFilePath =StringVar()
        self.imageFilePath = StringVar()
        self.labelFolder = Label(frame,textvariable=self.logFilePath).grid(row=0,column=1)
        self.labelImageFile = Label(frame,textvariable = self.imageFilePath).grid(row = 1,column=1)

        def selectLogFile(self):
            filename = askopenfilename()
            self.logFilePath.set(filename)

        def selectImageFile(self):
            imageFolder = askdirectory()
            self.imageFilePath.set(imageFolder)

root = Tk()
root.title("Geo Tagging")
root.geometry("600x100")
app = Application(root)
root.mainloop()

If your dictionary isn't too big maybe str + eval can do the work:

dict1 = {'one':1, 'two':2, 'three': {'three.1': 3.1, 'three.2': 3.2 }}
str1 = str(dict1)

dict2 = eval(str1)

print dict1==dict2

You can use ast.literal_eval instead of eval for additional security if the source is untrusted.

My understanding is that HEAD points the current branch, while ORIG_HEAD is used to store the previous HEAD before doing "dangerous" operations.

For example git-rebase and git-am record the original tip of branch before they apply any changes.

With Git 2.30 (Q1 2021), "git diff A...B(man)" learned "git diff --merge-base A B(man), which is a longer short-hand to say the same thing.

Thus you can do this using git diff --merge-base <branch> HEAD. This should be equivalent to git diff <branch>...HEAD but without the confusion of having to use range-notation in a diff.

Yes you can do that.

Here is an example:

a{
    background:IMAGE-URL;
    display:block;
    height:IMAGE-HEIGHT;
    width:IMAGE-WIDTH;
}

Of course you can modify the above example to your need. The important thing is to make it appear as a block (display:block) or an inline block (display:inline-block).

You are getting arithmetic overflow. this means you are trying to make a conversion impossible to be made. This error is thrown when you try to make a conversion and the destiny data type is not enough to convert the origin data. For example:

If you try to convert 100.52 to decimal(4,2) you will get this error. The number 100.52 requires 5 positions and 2 of them are decimal.

Try to change the decimal precision to something like 16,2 or higher. Try with few records first then use it to all your select.

It is the container of the Grid that is imposing on its width. In this case, that's a ListBoxItem, which is left-aligned by default. You can set it to stretch as follows:

<ListBox>
    <!-- other XAML omitted, you just need to add the following bit -->
    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Setter Property="HorizontalAlignment" Value="Stretch"/>
        </Style>
    </ListBox.ItemContainerStyle>
</ListBox>

Try This, It's easy way to find java installed path in Mac OS X,

GoTO

1 ) /Library i.e Macintosh HD/Library

2) Click on Library in that we find Java folder.

3) So final path is

/Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home

Hope so this is help for someone .

I used skimage. You can create a collection and access elements the standard way, i.e. col[index]. This will give you the RGB values.

from skimage.io import imread_collection

#your path 
col_dir = 'cats/*.jpg'

#creating a collection with the available images
col = imread_collection(col_dir)

Thank you, in PostgreSQL this works for boolean

SELECT
hat,
shoe,
boat,
false as placeholder
FROM
objects

DateTime.ToString("dd/MM/yyyy") may give the date in dd-MM-yyyy format. This depends on your short date format. If short date format is not as per format, we have to replace character '-' with '/' as below:

 date = DateTime.Now.ToString("dd/MM/yyyy").Replace('-','/');

You need to install a plugin, There is a free one from the eclipse foundation called the Web Tools Platform. It has all the development functionality that you'll need.

You can get the Java EE Edition of eclipse with has it pre-installed.

To create and run your first servlet:

1. New... Project... Dynamic Web Project.
2. Right click the project... New Servlet.
3. Write some code in the doGet() method.
4. Find the servers view in the Java EE perspective, it's usually one of the tabs at the bottom.
5. Right click in there and select new Server.
6. Select Tomcat X.X and a wizard will point you to finding the installation.
7. Right click the server you just created and select Add and Remove... and add your created web project.
8. Right click your servlet and select Run > Run on Server...

That should do it for you. You can use ant to build here if that's what you'd like but eclipse will actually do the build and automatically deploy the changes to the server. With Tomcat you might have to restart it every now and again depending on the change.

Generally, I agree with @kgrittn's advice. Go for it.

But to address your basic question about concat(): The new function concat() is useful if you need to deal with null values - and null has neither been ruled out in your question nor in the one you refer to.

If you can rule out null values, the good old (SQL standard) concatenation operator || is still the best choice, and @luis' answer is just fine:

SELECT col_a || col_b;

If either of your columns can be null, the result would be null in that case. You could defend with COALESCE:

SELECT COALESCE(col_a, '') || COALESCE(col_b, '');

But that get tedious quickly with more arguments. That's where concat() comes in, which never returns null, not even if all arguments are null. Per documentation:

NULL arguments are ignored.

SELECT concat(col_a, col_b);

The remaining corner case for both alternatives is where all input columns are null in which case we still get an empty string '', but one might want null instead (at least I would). One possible way:

SELECT CASE
          WHEN col_a IS NULL THEN col_b
          WHEN col_b IS NULL THEN col_a
          ELSE col_a || col_b
       END;

This gets more complex with more columns quickly. Again, use concat() but add a check for the special condition:

SELECT CASE WHEN (col_a, col_b) IS NULL THEN NULL
            ELSE concat(col_a, col_b) END;

How does this work?
(col_a, col_b) is shorthand notation for a row type expression ROW (col_a, col_b). And a row type is only null if all columns are null. Detailed explanation:

• NOT NULL constraint over a set of columns

Also, use concat_ws() to add separators between elements (ws for "with separator").

An expression like the one in Kevin's answer:

SELECT $1.zipcode || ' - ' || $1.city || ', ' || $1.state;

is tedious to prepare for null values in PostgreSQL 8.3 (without concat()). One way (of many):

SELECT COALESCE(
         CASE
            WHEN $1.zipcode IS NULL THEN $1.city
            WHEN $1.city    IS NULL THEN $1.zipcode
            ELSE $1.zipcode || ' - ' || $1.city
         END, '')
       || COALESCE(', ' || $1.state, '');

Function volatility is only STABLE

concat() and concat_ws() are STABLE functions, not IMMUTABLE because they can invoke datatype output functions (like timestamptz_out) that depend on locale settings.
Explanation by Tom Lane.

This prohibits their direct use in index expressions. If you know that the result is actually immutable in your case, you can work around this with an IMMUTABLE function wrapper. Example here:

• Does PostgreSQL support "accent insensitive" collations?

Try

public bool IsDivisible(int x, int n)
{
   return (x % n) == 0;
}

The modulus operator % returns the remainder after dividing x by n which will always be 0 if x is divisible by n.

For more information, see the % operator on MSDN.

In addition to above answers in Python 3, we may simply create a list of result values from a map as

li = []
for x in map(chr,[66,53,0,94]):
    li.append(x)

print (li)
>>>['B', '5', '\x00', '^']

We may generalize by another example where I was struck, operations on map can also be handled in similar fashion like in regex problem, we can write function to obtain list of items to map and get result set at the same time. Ex.

b = 'Strings: 1,072, Another String: 474 '
li = []
for x in map(int,map(int, re.findall('\d+', b))):
    li.append(x)

print (li)
>>>[1, 72, 474]

Try this:

$(".ui-widget-overlay").click(function () {
    $(".ui-icon.ui-icon-closethick").trigger("click");
}); 

In JavaScript:

/[^\w_]/g

^ negation, i.e. select anything not in the following set

\w any word character (i.e. any alphanumeric character, plus underscore)

_ negate the underscore, as it's considered a 'word' character

Usage example - const nonAlphaNumericChars = /[^\w_]/g;

The scheme is correct, User.ID must be the primary key of User, Job.ID should be the primary key of Job and Job.UserID should be a foreign key to User.ID. Also, your commands appear to be syntactically correct.

So what could be wrong? I believe you have at least a Job.UserID which doesn't have a pair in User.ID. For instance, if all values of User.ID are: 1,2,3,4,6,7,8 and you have a value of Job.UserID of 5 (which is not among 1,2,3,4,6,7,8, which are the possible values of UserID), you will not be able to create your foreign key constraint. Solution:

delete from Job where UserID in (select distinct User.ID from User);

will delete all jobs with nonexistent users. You might want to migrate these to a copy of this table which will contain archive data.

regex = re.compile("u'2022'",re.UNICODE)

From Oracle docs, Date.toString() method convert Date object to a String of the specific form - do not use toString method on Date object. Try to use:

String stringDate = new SimpleDateFormat(YOUR_STRING_PATTERN).format(yourDateObject);

Next step is parse stringDate to Date:

Date date = new SimpleDateFormat(OUTPUT_PATTERN).parse(stringDate);

Note that, parse method throws ParseException

I had this with an UIAlertControllerStyleActionSheet giving the user the option to take a photo with the camera or use one from library.

I tried a symbolic breakpoint on the error message

That showed me the error is produced by the intern use of a UICollectionView during presentation

[self presentViewController:alert animated:YES completion:nil];

I fixed this by explixitly setting the frame before presenting

[alert setPreferredContentSize: alert.view.frame.size];

Here is the complete methode that is working without the error

-(void)showImageSourceAlertFromSender:(id)sender{
UIButton *senderButton = (UIButton*)sender;
UIAlertController *alert = [UIAlertController alertControllerWithTitle:nil message:nil preferredStyle:UIAlertControllerStyleActionSheet];
UIAlertAction *cameraAction = [UIAlertAction actionWithTitle:@"Camera" style:UIAlertActionStyleDefault
                                                     handler:^(UIAlertAction *action) {
                                                         [self takePhoto];
                                                     }];
UIAlertAction *libraryAction = [UIAlertAction actionWithTitle:@"Library" style:UIAlertActionStyleDefault
                                                      handler:^(UIAlertAction *action) {
                                                          [self selectPhotoFromLibraryFromSender:sender];
                                                      }];
[alert addAction:cameraAction];
[alert addAction:libraryAction];
alert.popoverPresentationController.delegate = self;
alert.popoverPresentationController.sourceRect = senderButton.frame;
alert.popoverPresentationController.sourceView = self.view;

[alert setPreferredContentSize: alert.view.frame.size];

[self presentViewController:alert animated:YES completion:^(){
}];}

int total_Parson = Integer.parseInt(etRegularTickets.getText().toString());
int ticket_price=Integer.parseInt(TicketData.get(0).getTicket_price_regular());
total_ticket_amount = ticket_price * total_Parson;
etRegularPrice.setText(""+total_ticket_amount);

For checking spaces just with bash:

[[ "$str" = "${str% *}" ]] && echo "no spaces" || echo "has spaces"

You could do something along these lines (which worked in both Python v2.7.17 and v3.8.1 when I tested it/them):

def hi():
    # other code...
    hi.bye = 42  # Create function attribute.
    sigh = 10

hi()
print(hi.bye)  # -> 42

Functions are objects in Python and can have arbitrary attributes assigned to them.

If you're going to be doing this kind of thing often, you could implement something more generic by creating a function decorator that adds a this argument to each call to the decorated function.

This additional argument will give functions a way to reference themselves without needing to explicitly embed (hardcode) their name into the rest of the definition and is similar to the instance argument that class methods automatically receive as their first argument which is usually named self — I picked something different to avoid confusion, but like the self argument, it can be named whatever you wish.

Here's an example of that approach:

def add_this_arg(func):
    def wrapped(*args, **kwargs):
        return func(wrapped, *args, **kwargs)
    return wrapped

@add_this_arg
def hi(this, that):
    # other code...
    this.bye = 2 * that  # Create function attribute.
    sigh = 10

hi(21)
print(hi.bye)  # -> 42

Note

This doesn't work for class methods. Just use the self argument already passed being passed to instead of the method name. You can reference class-level attributes through type(self). See Function's attributes when in a class.

if you want to populate a table in SQL SERVER you can use while statement as follows:

declare @llenandoTabla INT = 0;
while @llenandoTabla < 10000
begin
insert into employeestable // Name of my table
(ID, FIRSTNAME, LASTNAME, GENDER, SALARY) // Parameters of my table
VALUES 
(555, 'isaias', 'perez', 'male', '12220') //values
set @llenandoTabla = @llenandoTabla + 1;
end

Hope it helps.

Try to avoid formatting in your query. You should return your data in a raw format and let the receiving application (e.g. a reporting service or end user app) do the formatting, i.e. rounding and so on.

Formatting the data in the server makes it harder (or even impossible) for you to further process your data. You usually want export the table or do some aggregation as well, like sum, average etc. As the numbers arrive as strings (varchar), there is usually no easy way to further process them. Some report designers will even refuse to offer the option to aggregate these 'numbers'.

Also, the end user will see the country specific formatting of the server instead of his own PC.

Also, consider rounding problems. If you round the values in the server and then still do some calculations (supposing the client is able to revert the number-strings back to a number), you will end up getting wrong results.

Some of it is possible, specifically accessing subtotals:

"In Excel 2010+, you can right-click on the values and select Show Values As –> % of Parent Row Total." (or % of Parent Column Total)

• And make sure the field in question is a number field that can be summed, it does not work for text fields for which only count is normally informative.

Source: http://datapigtechnologies.com/blog/index.php/excel-2010-pivottable-subtotals/

In that case, it's not needed. No extra threads will have been started up, you're not changing the exit code (which defaults to 0) - basically it's pointless.

When the docs say the method never returns normally, it means the subsequent line of code is effectively unreachable, even though the compiler doesn't know that:

System.exit(0);
System.out.println("This line will never be reached");

Either an exception will be thrown, or the VM will terminate before returning. It will never "just return".

It's very rare to be worth calling System.exit() IME. It can make sense if you're writing a command line tool, and you want to indicate an error via the exit code rather than just throwing an exception... but I can't remember the last time I used it in normal production code.

I think the default place for access logs is

%SystemDrive%\inetpub\logs\LogFiles

Otherwise, check under IIS Manager, select the computer on the left pane, and in the middle pane, go under "Logging" in the IIS area. There you will se the default location for all sites (this is however overridable on all sites)

You could also look into

%SystemDrive%\Windows\System32\LogFiles\HTTPERR

Which will contain similar log files that only represents errors.

l = [1, 2, 3]
print '\n'.join(['%i: %s' % (n, l[n]) for n in xrange(len(l))])

Razor syntax is here:

<input type="button" value="Create" onclick="location.href='@Url.Action("Create", "User")'" />

All boils down to if your server backend is timezone-agnostic or not. If it is not, then you need to assume that timezone of server is the same as client, or transfer information about client's timezone and include that also into calculations.

a PostgreSQL backend based example:

select '2009-09-28T08:00:00Z'::timestamp -> '2009-09-28 08:00:00' (wrong for 10am)
select '2009-09-28T08:00:00Z'::timestamptz -> '2009-09-28 10:00:00+02'
select '2009-09-28T08:00:00Z'::timestamptz::timestamp -> '2009-09-28 10:00:00'

The last one is probably what you want to use in database, if you are not willing properly implement timezone logic.

Using .format for string formatting,

mylist = ['x', 3, 'b']
print("[{0}]".format(', '.join(map(str, mylist))))

Output:

[x, 3, b]

Explanation:

1. map is used to map each element of the list to string type.
2. The elements are joined together into a string with , as separator.
3. We use [ and ] in the print statement to show the list braces.

Reference: .format for string formatting PEP-3101

Fragment Listener

If a fragment needs to communicate events to the activity, the fragment should define an interface as an inner type and require that the activity must implement this interface:

import android.support.v4.app.Fragment;

public class MyListFragment extends Fragment {
  // ...
  // Define the listener of the interface type
  // listener is the activity itself
  private OnItemSelectedListener listener;

  // Define the events that the fragment will use to communicate
  public interface OnItemSelectedListener {
    public void onRssItemSelected(String link);
  }

  // Store the listener (activity) that will have events fired once the fragment is attached
  @Override
  public void onAttach(Activity activity) {
    super.onAttach(activity);
      if (activity instanceof OnItemSelectedListener) {
        listener = (OnItemSelectedListener) activity;
      } else {
        throw new ClassCastException(activity.toString()
            + " must implement MyListFragment.OnItemSelectedListener");
      }
  }

  // Now we can fire the event when the user selects something in the fragment
  public void onSomeClick(View v) {
     listener.onRssItemSelected("some link");
  }
}

and then in the activity:

import android.support.v4.app.FragmentActivity;

public class RssfeedActivity extends FragmentActivity implements
  MyListFragment.OnItemSelectedListener {
    DetailFragment fragment;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_rssfeed);
      fragment = (DetailFragment) getSupportFragmentManager()
            .findFragmentById(R.id.detailFragment);
  }

  // Now we can define the action to take in the activity when the fragment event fires
  @Override
  public void onRssItemSelected(String link) {
      if (fragment != null && fragment.isInLayout()) {
          fragment.setText(link);
      }
  }
}

There are multiple ways to check if a value exists in the database. Let me demonstrate how this can be done properly with PDO and mysqli.

PDO

PDO is the simpler option. To find out whether a value exists in the database you can use prepared statement and fetchColumn(). There is no need to fetch any data so we will only fetch 1 if the value exists.

<?php

// Connection code. 
$options = [
    \PDO::ATTR_ERRMODE            => \PDO::ERRMODE_EXCEPTION,
    \PDO::ATTR_EMULATE_PREPARES   => false,
];
$pdo = new \PDO('mysql:host=localhost;port=3306;dbname=test;charset=utf8mb4', 'testuser', 'password', $options);

// Prepared statement
$stmt = $pdo->prepare('SELECT 1 FROM tblUser WHERE email=?');
$stmt->execute([$_POST['email']]);
$exists = $stmt->fetchColumn(); // either 1 or null

if ($exists) {
    echo 'Email exists in the database.';
} else {
    // email doesn't exist yet
}

For more examples see: How to check if email exists in the database?

MySQLi

As always mysqli is a little more cumbersome and more restricted, but we can follow a similar approach with prepared statement.

<?php

// Connection code
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new \mysqli('localhost', 'testuser', 'password', 'test');
$mysqli->set_charset('utf8mb4');

// Prepared statement
$stmt = $mysqli->prepare('SELECT 1 FROM tblUser WHERE email=?');
$stmt->bind_param('s', $_POST['email']);
$stmt->execute();
$exists = (bool) $stmt->get_result()->fetch_row(); // Get the first row from result and cast to boolean

if ($exists) {
    echo 'Email exists in the database.';
} else {
    // email doesn't exist yet
}

Instead of casting the result row(which might not even exist) to boolean, you can also fetch COUNT(1) and read the first item from the first row using fetch_row()[0]

For more examples see: How to check whether a value exists in a database using mysqli prepared statements

Minor remarks

• If someone suggests you to use mysqli_num_rows(), don't listen to them. This is a very bad approach and could lead to performance issues if misused.
• Don't use real_escape_string(). This is not meant to be used as a protection against SQL injection. If you use prepared statements correctly you don't need to worry about any escaping.
• If you want to check if a row exists in the database before you try to insert a new one, then it is better not to use this approach. It is better to create a unique key in the database and let it throw an exception if a duplicate value exists.

I think as a rule of thumb, if your if-expression can be re-written as

const bool local_predicate = *if-expression*;
if (local_predicate) ...

such that it causes NO WARNINGS, then THAT should be the preferred style for the if-expression. (I know I get warnings when I assign an old C BOOL (#define BOOL int) to a C++ bool, let alone pointers.)

You should use

<input type="submit" value="submit" />

inside your form.

and add action into your form tag for example:

<form action="booking.php" method="post">

It's post your form into action which you choose.

From php you can get this value by

$_POST['booking-check'];

It will only push the new commits. It won't push the whole "master" branch. That is part of the benefit of working with a Distributed Version Control System. Git figures out what is actually needed and only pushes those pieces. If the branch you are on has been changed and pushed by someone else you'll need to pull first. Then push your commits.

Before Java 5.0, use -Xdebug and -Xrunjdwp arguments. These options will still work in later versions, but it will run in interpreted mode instead of JIT, which will be slower.

From Java 5.0, it is better to use the -agentlib:jdwp single option:

-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=1044

Options on -Xrunjdwp or agentlib:jdwp arguments are :

• transport=dt_socket : means the way used to connect to JVM (socket is a good choice, it can be used to debug a distant computer)
• address=8000 : TCP/IP port exposed, to connect from the debugger,
• suspend=y : if 'y', tell the JVM to wait until debugger is attached to begin execution, otherwise (if 'n'), starts execution right away.

You can use rows and cols:

cout << "Width : " << src.cols << endl;
cout << "Height: " << src.rows << endl;

or size():

cout << "Width : " << src.size().width << endl;
cout << "Height: " << src.size().height << endl;

Firefox does allow you to store data in the clipboard, but due to security implications it is disabled by default. See how to enable it in "Granting JavaScript access to the clipboard" in the Mozilla Firefox knowledge base.

The solution offered by amdfan is the best if you are having a lot of users and configuring their browser isn't an option. Though you could test if the clipboard is available and provide a link for changing the settings, if the users are tech savvy. The JavaScript editor TinyMCE follows this approach.

Since other SO answers link to this question it's worth noting that there is another option now in PyOxidizer.

It's a rust utility which works in some of the same ways as pyinstaller, however has some additional features detailed here, to summarize the key ones:

• Single binary of all packages by default with the ability to do a zero-copy load of modules into memory, vs pyinstaller extracting them to a temporary directory when using onefile mode
• Ability to produce a static linked binary

(One other advantage of pyoxidizer is that it does not seem to suffer from the GLIBC_X.XX not found problem that can crop up with pyinstaller if you've created your binary on a system that has a glibc version newer than the target system).

Overall pyinstaller is much simpler to use than PyOxidizer, which often requires some complexity in the configuration file, and it's less Pythony since it's written in Rust and uses a configuration file format not very familiar in the Python world, but PyOxidizer does some more advanced stuff, especially if you are looking to produce single binaries (which is not pyinstaller's default).

Does replacing a character in a String with a null character even work in Java? I know that '\0' will terminate a c-string.

That depends on how you define what is working. Does it replace all occurrences of the target character with '\0'? Absolutely!

String s = "food".replace('o', '\0');
System.out.println(s.indexOf('\0')); // "1"
System.out.println(s.indexOf('d')); // "3"
System.out.println(s.length()); // "4"
System.out.println(s.hashCode() == 'f'*31*31*31 + 'd'); // "true"

Everything seems to work fine to me! indexOf can find it, it counts as part of the length, and its value for hash code calculation is 0; everything is as specified by the JLS/API.

It DOESN'T work if you expect replacing a character with the null character would somehow remove that character from the string. Of course it doesn't work like that. A null character is still a character!

String s = Character.toString('\0');
System.out.println(s.length()); // "1"
assert s.charAt(0) == 0;

It also DOESN'T work if you expect the null character to terminate a string. It's evident from the snippets above, but it's also clearly specified in JLS (10.9. An Array of Characters is Not a String):

In the Java programming language, unlike C, an array of char is not a String, and neither a String nor an array of char is terminated by '\u0000' (the NUL character).

Would this be the culprit to the funky characters?

Now we're talking about an entirely different thing, i.e. how the string is rendered on screen. Truth is, even "Hello world!" will look funky if you use dingbats font. A unicode string may look funky in one locale but not the other. Even a properly rendered unicode string containing, say, Chinese characters, may still look funky to someone from, say, Greenland.

That said, the null character probably will look funky regardless; usually it's not a character that you want to display. That said, since null character is not the string terminator, Java is more than capable of handling it one way or another.

Now to address what we assume is the intended effect, i.e. remove all period from a string, the simplest solution is to use the replace(CharSequence, CharSequence) overload.

System.out.println("A.E.I.O.U".replace(".", "")); // AEIOU

The replaceAll solution is mentioned here too, but that works with regular expression, which is why you need to escape the dot meta character, and is likely to be slower.

is the ajax uploader refreshing your input element? if so you should consider using .live() method.

 $('#imageFile').live('change', function(){ uploadFile(); });

update:

from jQuery 1.7+ you should use now .on()

 $(parent_element_selector_here or document ).on('change','#imageFile' , function(){ uploadFile(); });

From my little date difference calculator:

var startDate = new Date(2000, 1-1, 1);  // 2000-01-01
var endDate =   new Date();              // Today

// Calculate the difference of two dates in total days
function diffDays(d1, d2)
{
  var ndays;
  var tv1 = d1.valueOf();  // msec since 1970
  var tv2 = d2.valueOf();

  ndays = (tv2 - tv1) / 1000 / 86400;
  ndays = Math.round(ndays - 0.5);
  return ndays;
}

So you would call:

var nDays = diffDays(startDate, endDate);

(Full source at http://david.tribble.com/src/javascript/jstimespan.html.)

Addendum

The code can be improved by changing these lines:

  var tv1 = d1.getTime();  // msec since 1970
  var tv2 = d2.getTime();

Just use

<a [ngClass]="{'disabled': your_condition}"> This a tag is disabled</a>

Example:

 <a [ngClass]="{'disabled': name=='junaid'}"> This a tag is disabled</a>

Use Set in Python

>>> a = [2,4]
>>> b = [1,4,3]
>>> set(a) - set(b)
set([2])

XCode 7.1 iOS 7, 8, 9:

just put these two lines in your TabelViewCell:

    self.layoutMargins = UIEdgeInsetsZero;
    self.preservesSuperviewLayoutMargins = false;

That worked for me

Use .closest() with a selector:

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

Select ID, IsNull(Cast(ParentID as varchar(max)),'') from Patients

This is needed because field ParentID is not varchar/nvarchar type. This will do the trick:

Select ID, IsNull(ParentID,'') from Patients

I was having the same exception on the device Z3 Compact D5803 - 6.0.1

I went opened the .buckconfig file and changed the line:

target = Google Inc.:Google APIs:23

to

target = Google Inc.:Google APIs:24

Because i saw in SDK Manager that Android 6.X has api level 24.

In first activity u can send intent using startActivityForResult() and then get result from second activity after it finished using setResult.

MainActivity.class

public class MainActivity extends AppCompatActivity {

    private static final int SECOND_ACTIVITY_RESULT_CODE = 0;

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

    // "Go to Second Activity" button click
    public void onButtonClick(View view) {

        // Start the SecondActivity
        Intent intent = new Intent(this, SecondActivity.class);
        // send intent for result 
        startActivityForResult(intent, SECOND_ACTIVITY_RESULT_CODE);
    }

    // This method is called when the second activity finishes
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        // check that it is the SecondActivity with an OK result
        if (requestCode == SECOND_ACTIVITY_RESULT_CODE) {
            if (resultCode == RESULT_OK) {

                // get String data from Intent
                String returnString = data.getStringExtra("keyName");

                // set text view with string
                TextView textView = (TextView) findViewById(R.id.textView);
                textView.setText(returnString);
            }
        }
    }
}

SecondActivity.class

public class SecondActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);
    }

    // "Send text back" button click
    public void onButtonClick(View view) {

        // get the text from the EditText
        EditText editText = (EditText) findViewById(R.id.editText);
        String stringToPassBack = editText.getText().toString();

        // put the String to pass back into an Intent and close this activity
        Intent intent = new Intent();
        intent.putExtra("keyName", stringToPassBack);
        setResult(RESULT_OK, intent);
        finish();
    }
}

I would add, and also to answer the question find mean bin values using histogram2d python that the scipy also have a function specially designed to compute a bidimensional binned statistic for one or more sets of data

import numpy as np
from scipy.stats import binned_statistic_2d

x = np.random.rand(100)
y = np.random.rand(100)
values = np.random.rand(100)
bin_means = binned_statistic_2d(x, y, values, bins=10).statistic

the function scipy.stats.binned_statistic_dd is a generalization of this funcion for higher dimensions datasets

You can return more than one value using list also. Check the code below

def newFn():    #your function
  result = []    #defining blank list which is to be return
  r1 = 'return1'    #first value
  r2 = 'return2'    #second value
  result.append(r1)    #adding first value in list
  result.append(r2)    #adding second value in list
  return result    #returning your list

ret_val1 = newFn()[1]    #you can get any desired result from it
print ret_val1    #print/manipulate your your result

I just made a class to handle this with Generics, so it can be used with all the object types that are serializable:

public class SerializableManager {

    /**
     * Saves a serializable object.
     *
     * @param context The application context.
     * @param objectToSave The object to save.
     * @param fileName The name of the file.
     * @param <T> The type of the object.
     */

    public static <T extends Serializable> void saveSerializable(Context context, T objectToSave, String fileName) {
        try {
            FileOutputStream fileOutputStream = context.openFileOutput(fileName, Context.MODE_PRIVATE);
            ObjectOutputStream objectOutputStream = new ObjectOutputStream(fileOutputStream);

            objectOutputStream.writeObject(objectToSave);

            objectOutputStream.close();
            fileOutputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    /**
     * Loads a serializable object.
     *
     * @param context The application context.
     * @param fileName The filename.
     * @param <T> The object type.
     *
     * @return the serializable object.
     */

    public static<T extends Serializable> T readSerializable(Context context, String fileName) {
        T objectToReturn = null;

        try {
            FileInputStream fileInputStream = context.openFileInput(fileName);
            ObjectInputStream objectInputStream = new ObjectInputStream(fileInputStream);
            objectToReturn = (T) objectInputStream.readObject();

            objectInputStream.close();
            fileInputStream.close();
        } catch (IOException | ClassNotFoundException e) {
            e.printStackTrace();
        }

        return objectToReturn;
    }

    /**
     * Removes a specified file.
     *
     * @param context The application context.
     * @param filename The name of the file.
     */

    public static void removeSerializable(Context context, String filename) {
        context.deleteFile(filename);
    }

}

It seems odd that this method doesn't exist. Is it time to add it finally?

If you wanted to you could something like the following:

var _addEventListener = EventTarget.prototype.addEventListener;
var _removeEventListener = EventTarget.prototype.removeEventListener;
EventTarget.prototype.events = {};
EventTarget.prototype.addEventListener = function(name, listener, etc) {
  var events = EventTarget.prototype.events;
  if (events[name] == null) {
    events[name] = [];
  }

  if (events[name].indexOf(listener) == -1) {
    events[name].push(listener);
  }

  _addEventListener(name, listener);
};
EventTarget.prototype.removeEventListener = function(name, listener) {
  var events = EventTarget.prototype.events;

  if (events[name] != null && events[name].indexOf(listener) != -1) {
    events[name].splice(events[name].indexOf(listener), 1);
  }

  _removeEventListener(name, listener);
};
EventTarget.prototype.hasEventListener = function(name) {
  var events = EventTarget.prototype.events;
  if (events[name] == null) {
    return false;
  }

  return events[name].length;
};

There's a very easy way if you were using a web application just follow this link.

just do in eclipse :

File > import > web > war file

Then select the war file of your app :)) very easy !!

I've just written a plugin which uses .firstElementChild if possible, and falls back to iterating over each individual node if necessary:

(function ($) {
    var useElementChild = ('firstElementChild' in document.createElement('div'));

    $.fn.firstChild = function () {
        return this.map(function() {
            if (useElementChild) {
                return this.firstElementChild;
            } else {
                var node = this.firstChild;
                while (node) {
                    if (node.type === 1) {
                        break;
                    }
                    node = node.nextSibling;
                }
                return node;
            }
        });
    };
})(jQuery);

It's not as fast as a pure DOM solution, but in jsperf tests under Chrome 24 it was a couple of orders of magnitude faster than any other jQuery selector-based method.

SQL Server 2008 databases are version 655. SQL Server 2008 R2 databases are 661. You are trying to attach an 2008 R2 database (v. 661) to an 2008 instance and this is not supported. Once the database has been upgraded to an 2008 R2 version, it cannot be downgraded. You'll have to either upgrade your 2008 SP2 instance to R2, or you have to copy out the data in that database into an 2008 database (eg using the data migration wizard, or something equivalent).

The message is misleading, to say the least, it says 662 because SQL Server 2008 SP2 does support 662 as a database version, this is when 15000 partitions are enabled in the database, see Support for 15000 Partitions.docx. Enabling the support bumps the DB version to 662, disabling it moves it back to 655. But SQL Server 2008 SP2 does not support 661 (the R2 version).

I think library is a set of utilities to reach a goal (for example, sockets, cryptography, etc). Framework is library + RUNTIME EINVIRONNEMENT. For example, ASP.NET is a framework: it accepts HTTP requests, create page object, invoke lyfe cicle events, etc. Framework does all this, you write a bit of code which will be run at a specific time of the life cycle of current request!

Anyway, very interestering question!

One liner explanation

The standard versioning system is major.minor.build (e.g. 2.4.1)

npm checks and fixes the version of a particular package based on these characters

~ : major version is fixed, minor version is fixed, matches any build number

e.g. : ~2.4.1 means it will check for 2.4.x where x is anything

^ : major version is fixed, matches any minor version, matches any build number

e.g. : ^2.4.1 means it will check for 2.x.x where x is anything

To understand how a docker image was built, use the docker history --no-trunc command.

You can build a docker file from an image, but it will not contain everything you would want to fully understand how the image was generated. Reasonably what you can extract is the MAINTAINER, ENV, EXPOSE, VOLUME, WORKDIR, ENTRYPOINT, CMD, and ONBUILD parts of the dockerfile.

The following script should work for you:

#!/bin/bash
docker history --no-trunc "$1" | \
sed -n -e 's,.*/bin/sh -c #(nop) \(MAINTAINER .*[^ ]\) *0 B,\1,p' | \
head -1
docker inspect --format='{{range $e := .Config.Env}}
ENV {{$e}}
{{end}}{{range $e,$v := .Config.ExposedPorts}}
EXPOSE {{$e}}
{{end}}{{range $e,$v := .Config.Volumes}}
VOLUME {{$e}}
{{end}}{{with .Config.User}}USER {{.}}{{end}}
{{with .Config.WorkingDir}}WORKDIR {{.}}{{end}}
{{with .Config.Entrypoint}}ENTRYPOINT {{json .}}{{end}}
{{with .Config.Cmd}}CMD {{json .}}{{end}}
{{with .Config.OnBuild}}ONBUILD {{json .}}{{end}}' "$1"

I use this as part of a script to rebuild running containers as images: https://github.com/docbill/docker-scripts/blob/master/docker-rebase

The Dockerfile is mainly useful if you want to be able to repackage an image.

The thing to keep in mind, is a docker image can actually just be the tar backup of a real or virtual machine. I have made several docker images this way. Even the build history shows me importing a huge tar file as the first step in creating the image...

Try this:

SELECT CONVERT(date, GETDATE())

According to one of the first Google search hits: http://www.csharp-examples.net/string-format-datetime/

// Where 'dt' is the DateTime object...
String.Format("{0:dd-MM-yyyy}", dt);

Instead of using the ifelse as in the above example, one can also prefilter the data prior to labeling based on some threshold values, this saves a lot of work for the plotting device:

xlimit <- 36
ylimit <- 24
ggplot(myData)+geom_point(aes(myX,myY))+
    geom_label(data=myData[myData$myX > xlimit & myData$myY> ylimit,], aes(myX,myY,myLabel))

this is what it worked for me:

select * from table
where column
BETWEEN STR_TO_DATE('29/01/15', '%d/%m/%Y')
 AND STR_TO_DATE('07/10/15', '%d/%m/%Y')

Please, note that I had to change STR_TO_DATE(column, '%d/%m/%Y') from previous solutions, as it was taking ages to load

How about this approach, which splits the problem into two parts:

• Using jQuery, it shows a decrementing counter below the textarea, which turns red when it hits zero but still allows the user to type.
• I use a separate string length validator (server and client-side) to actually prevent submission of the form if the number of chatacters in the textarea is greater than 160.

My textarea has an id of Message, and the span in which I display the number of remaining characters has an id of counter. The css class of error gets applied when the number of remaining characters hits zero.

var charactersAllowed = 160;

$(document).ready(function () {
    $('#Message').keyup(function () {
        var left = charactersAllowed - $(this).val().length;
        if (left < 0) {
            $('#counter').addClass('error');
            left = 0;
        }
        else {
            $('#counter').removeClass('error');
        }
        $('#counter').text('Characters left: ' + left);
    });
});

Without java.io.* it can be done like this.

String trace = e.toString() + "\n";                     

for (StackTraceElement e1 : e.getStackTrace()) {
    trace += "\t at " + e1.toString() + "\n";
}   

And then the trace variable holds your stack trace. Output also holds the initial cause, the output is identical to printStackTrace()

Example, printStackTrace() yields:

java.io.FileNotFoundException: / (Is a directory)
    at java.io.FileOutputStream.open0(Native Method)
    at java.io.FileOutputStream.open(FileOutputStream.java:270)
    at java.io.FileOutputStream.<init>(FileOutputStream.java:213)
    at java.io.FileOutputStream.<init>(FileOutputStream.java:101)
    at Test.main(Test.java:9)

The trace String holds, when printed to stdout

java.io.FileNotFoundException: / (Is a directory)
     at java.io.FileOutputStream.open0(Native Method)
     at java.io.FileOutputStream.open(FileOutputStream.java:270)
     at java.io.FileOutputStream.<init>(FileOutputStream.java:213)
     at java.io.FileOutputStream.<init>(FileOutputStream.java:101)
     at Test.main(Test.java:9)

It is really simple.

googleMap.setInfoWindowAdapter(new InfoWindowAdapter() {

            // Use default InfoWindow frame
            @Override
            public View getInfoWindow(Marker marker) {              
                return null;
            }           

            // Defines the contents of the InfoWindow
            @Override
            public View getInfoContents(Marker marker) {

                // Getting view from the layout file info_window_layout
                View v = getLayoutInflater().inflate(R.layout.info_window_layout, null);

                // Getting reference to the TextView to set title
                TextView note = (TextView) v.findViewById(R.id.note);

                note.setText(marker.getTitle() );

                // Returning the view containing InfoWindow contents
                return v;

            }

        });

Just add above code in your class where you are using GoogleMap. R.layout.info_window_layout is our custom layout that is showing the view that will come in place of infowindow. I just added the textview here. You can add additonal view here to make it like the sample snap. My info_window_layout was

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:orientation="vertical" 
    >

        <TextView 
        android:id="@+id/note"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

I hope it will help. We can find a working example of custom infowindow at http://wptrafficanalyzer.in/blog/customizing-infowindow-contents-in-google-map-android-api-v2-using-infowindowadapter/#comment-39731

EDITED : This code is shows how we can add custom view on infoWindow. This code did not handle the clicks on Custom View items. So it is close to answer but not exactly the answer that's why It is not accepted as answer.

I have written a node module that provides a wrapper around setInterval using moment durations providing a declarative interface:

npm install every-moment

var every = require('every-moment');

var timer = every(5, 'seconds', function() {
    console.log(this.duration);
});

every(2, 'weeks', function() {
    console.log(this.duration);
    timer.stop();
    this.set(1, 'week');
    this.start();
});

I use FileZilla and it works fine with SFTP (SSH File Transfer Protocol). Follow these steps to install it and configure it:

1. Install FileZilla via terminal:

sudo apt-get install filezilla

2. Open the program and go to File -> Site Manager... or simply type Ctrl+S

3. The following window should appear:

4. Enter the name of your host, select the port (usually 22 for ssh/scp/sftp) and choose SFTP - SSH File Transfer Protocol as protocol and optionally set the Logon Type to Normal if authentication is needed, resp. enter your data.

The evaluation of condition resulted in an NA. The if conditional must have either a TRUE or FALSE result.

if (NA) {}
## Error in if (NA) { : missing value where TRUE/FALSE needed

This can happen accidentally as the results of calculations:

if(TRUE && sqrt(-1)) {}
## Error in if (TRUE && sqrt(-1)) { : missing value where TRUE/FALSE needed

To test whether an object is missing use is.na(x) rather than x == NA.

See also the related errors:

Error in if/while (condition) { : argument is of length zero

Error in if/while (condition) : argument is not interpretable as logical

if (NULL) {}
## Error in if (NULL) { : argument is of length zero

if ("not logical") {}
## Error: argument is not interpretable as logical

if (c(TRUE, FALSE)) {}
## Warning message:
## the condition has length > 1 and only the first element will be used

If you do not want to make your control runat server in case you need the ID or simply don't want to add it to the viewstate,

<div id="formSpinner" class="<%= _css %>">
</div>

in the back-end:

protected string _css = "modalBackground";

I won't address the READ UNCOMMITTED argument, just your original question.

Yes, you need WITH(NOLOCK) on each table of the join. No, your queries are not the same.

Try this exercise. Begin a transaction and insert a row into table1 and table2. Don't commit or rollback the transaction yet. At this point your first query will return successfully and include the uncommitted rows; your second query won't return because table2 doesn't have the WITH(NOLOCK) hint on it.

pragma is your best bet:

<meta http-equiv="Pragma" content="no-cache">

Use this script

Your problem is that the top and left properties require a unit of measure, not just a bare number:

div.style.top = "200px";
div.style.left = "200px";

If you don't mind using your mouse a little bit:

• Start your terminal,
• select a file,
• select Open Tab.

This creates a new tab on the terminal which you can run Vim on. Now use your mouse to shift to/from the terminal. I prefer this instead of always having to type (:shell and exit).

I would just use

if sorted(lst) == lst:
    # code here

unless it's a very big list in which case you might want to create a custom function.

if you are just going to sort it if it's not sorted, then forget the check and sort it.

lst.sort()

and don't think about it too much.

if you want a custom function, you can do something like

def is_sorted(lst, key=lambda x: x):
    for i, el in enumerate(lst[1:]):
        if key(el) < key(lst[i]): # i is the index of the previous element
            return False
    return True

This will be O(n) if the list is already sorted though (and O(n) in a for loop at that!) so, unless you expect it to be not sorted (and fairly random) most of the time, I would, again, just sort the list.

For this problem Onpagechange listener is the best one But it will also have one small mistake that is it will not detect the starting time time of 0th position Once you will change the page it will starts to detect the Page selected position...For this problem I fount the easiest solution

1.You have to maintain the selected position value then use it....
2. Case 1: At the starting of the position is always Zero....
Case 2: Suppose if you set the current item means you will set that value into maintain position
3.Then do your action with the use of that maintain in your activity...

Public int maintain=0;
myViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int i, float v, int i2) {
             //Toast.makeText(MyActivity.this, i+"  Is Selected  "+data.size(), Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onPageSelected( int i) {
          // here you will get the position of selected page
            maintain = i;


        }

        @Override
        public void onPageScrollStateChanged(int i) {

        }
    });


updateButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            Toast.makeText(MyActivity.this, i+"  Is Selected  "+data.size(), Toast.LENGTH_SHORT).show();
            data.set(maintain, "Replaced "+maintain);         
            myViewPager.getAdapter().notifyDataSetChanged();
        }
    });

document.location.href = newUrl;

The easiest way is to use sed (or perl):

sed -i -e 's/abc/XYZ/g' /tmp/file.txt

Which will invoke sed to do an in-place edit due to the -i option. This can be called from bash.

If you really really want to use just bash, then the following can work:

while read a; do
    echo ${a//abc/XYZ}
done < /tmp/file.txt > /tmp/file.txt.t
mv /tmp/file.txt{.t,}

This loops over each line, doing a substitution, and writing to a temporary file (don't want to clobber the input). The move at the end just moves temporary to the original name.

For Mac users:

sed -i '' 's/abc/XYZ/g' /tmp/file.txt (See the comment below why)

I've experimented with typing "exit for" a few times and noticed it worked and VB didn't yell at me. It's an option I guess but it just looked bad.

I think the best option is similar to that shared by Tobias. Just put your code in a function and have it return when you want to break out of your loops. Looks cleaner too.

For Each item In itemlist
    For Each item1 In itemlist1
        If item1 = item Then
            Return item1
        End If
    Next
Next

I tried to delete a column while using the package data.table and got an unexpected result. I kind of think the following might be worth posting. Just a little cautionary note.

[ Edited by Matthew ... ]

DF = read.table(text = "
     fruit state grade y1980 y1990 y2000
     apples Ohio   aa    500   100   55
     apples Ohio   bb      0     0   44
     apples Ohio   cc    700     0   33
     apples Ohio   dd    300    50   66
", sep = "", header = TRUE, stringsAsFactors = FALSE)

DF[ , !names(DF) %in% c("grade")]   # all columns other than 'grade'
   fruit state y1980 y1990 y2000
1 apples  Ohio   500   100    55
2 apples  Ohio     0     0    44
3 apples  Ohio   700     0    33
4 apples  Ohio   300    50    66

library('data.table')
DT = as.data.table(DF)

DT[ , !names(dat4) %in% c("grade")]    # not expected !! not the same as DF !!
[1]  TRUE  TRUE FALSE  TRUE  TRUE  TRUE

DT[ , !names(DT) %in% c("grade"), with=FALSE]    # that's better
    fruit state y1980 y1990 y2000
1: apples  Ohio   500   100    55
2: apples  Ohio     0     0    44
3: apples  Ohio   700     0    33
4: apples  Ohio   300    50    66

Basically, the syntax for data.table is NOT exactly the same as data.frame. There are in fact lots of differences, see FAQ 1.1 and FAQ 2.17. You have been warned!

Your best options are CreateProcess() or CreateThread(). There is more information on porting here.

colors = {
    reset: '\033[0m',

    //text color

    black: '\033[30m',
    red: '\033[31m',
    green: '\033[32m',
    yellow: '\033[33m',
    blue: '\033[34m',
    magenta: '\033[35m',
    cyan: '\033[36m',
    white: '\033[37m',

    //background color

    blackBg: '\033[40m',
    redBg: '\033[41m',
    greenBg: '\033[42m',
    yellowBg: '\033[43m',

    magentaBg: '\033[45m',
    cyanBg: '\033[46m',
    whiteBg: '\033[47m'
}

console.log('\033[31m this is red color on text');
console.log('\033[0m this is reset');
console.log('\033[41m this is red color on background');

The problem I see here is that "sum" is an aggregate function.

first, you need to fix the query itself.

Select sum(c_counts + f_counts) total, [column to group sums by]
from table
group by [column to group sums by]

then, you can sort it:

Select *
from (query above) a
order by total

EDIT: But see post by Virat. Perhaps what you want is not the sum of your total fields over a group, but just the sum of those fields for each record. In that case, Virat has the right solution.

request.stream is the stream of raw data passed to the application by the WSGI server. No parsing is done when reading it, although you usually want request.get_data() instead.

data = request.stream.read()

The stream will be empty if it was previously read by request.data or another attribute.

Just want to point out something on @codingbadger answer. When using "ProgressBarRenderer" you should always check for "ProgressBarRenderer.IsSupported" before using the class. For me, this has been a nightmare with Visual Styles errors in Win7 that I couldn't fix. So, a better approach and workaround for the solution would be:

Rectangle clip = new Rectangle(rect.X, rect.Y, (int)Math.Round(((float)Value / Maximum) * rect.Width), rect.Height);
if (ProgressBarRenderer.IsSupported)
  ProgressBarRenderer.DrawHorizontalChunks(g, clip);
else
  g.FillRectangle(new SolidBrush(this.ForeColor), clip);

Notice that the fill will be a simple rectangle and not chunks. Chunks will be used only if ProgressBarRenderer is supported

Typically, one follow the conventions used in the language's standard library.

This is discouraged (if you want to create/distribute a clean Docker image), since the PATH variable is set by /etc/profile script, the value can be overridden.

head /etc/profile:

if [ "`id -u`" -eq 0 ]; then
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
else
  PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games"
fi
export PATH

At the end of the Dockerfile, you could add:

RUN echo "export PATH=$PATH" > /etc/environment

So PATH is set for all users.

on Rails 6 you can now do something like

rake db:seed:replant This Truncates tables of each database for current environment and loads the seeds
