This is a variation of the anwser by Muhammad Rehan Saeed, with the class getting parasitically attached to the existing .net core MVC class of the same name, so that everything just works.

namespace Microsoft.AspNetCore.Mvc
{
    /// <summary>
    /// <see cref="IUrlHelper"/> extension methods.

You can load HTML page partial, in your case is everything inside div#mytable.

setTimeout(function(){
   $( "#mytable" ).load( "your-current-page.html #mytable" );
}, 2000); //refresh every 2 seconds

more information read this http://api.jquery.com/load/

Update Code (if you don't want it auto-refresh)

<button id="refresh-btn">Refresh Table</button>

<script>
$(document).ready(function() {

   function RefreshTable() {
       $( "#mytable" ).load( "your-current-page.html #mytable" );
   }

   $("#refresh-btn").on("click", RefreshTable);

   // OR CAN THIS WAY
   //
   // $("#refresh-btn").on("click", function() {
   //    $( "#mytable" ).load( "your-current-page.html #mytable" );
   // });


});
</script>

I had the same error using an UpdateView

I had this:

if form.is_valid() and form2.is_valid():
    form.save()
    form2.save()
    return HttpResponseRedirect(self.get_success_url())

and I solved just doing:

if form.is_valid() and form2.is_valid():
    form.save()
    form2.save()
    return HttpResponseRedirect(reverse_lazy('adopcion:solicitud_listar'))

It looks like there was an issue with my migration.

I ran ./manage.py schemamigration research --auto and found that many of the fields didn't have a default specified.

So, I ran ./manage.py schemamigration research --init followed by ./manage.py migrate research

Rerunning the server from there did the trick!

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

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

If anyone else stuck on same point, following solved my problem.

In web.xml

 <listener>
            <listener-class>
                    org.springframework.web.context.request.RequestContextListener 
            </listener-class>
  </listener>

In Session component

@Component
@Scope(value = "session",  proxyMode = ScopedProxyMode.TARGET_CLASS)

In pom.xml

    <dependency>
        <groupId>cglib</groupId>
        <artifactId>cglib</artifactId>
        <version>3.1</version>
    </dependency>

Check your imports. There could be two classes with the same name. Either from your code or from a library you are using. Personally that was the issue.

data: {"csrfmiddlewaretoken" : "{{csrf_token}}"}

You see "403 (FORBIDDEN)", because you don`t send "csrfmiddlewaretoken" parameter. In template each form has this: {% csrf_token %}. You should add "csrfmiddlewaretoken" to your ajax data dictionary. My example is sending "product_code" and "csrfmiddlewaretoken" to app "basket" view "remove":

$(function(){
    $('.card-body').on('click',function(){
        $.ajax({
          type: "post",
          url: "{% url 'basket:remove'%}",
          data: {"product_code": "07316", "csrfmiddlewaretoken" : "{{csrf_token}}" }
        });
    })
});

Make sure your django session backend is configured properly in settings.py. Then try this,

class CustomMiddleware(object):
  def process_request(self,request:HttpRequest):
      get_token(request)

Add this middleware in settings.py under MIDDLEWARE_CLASSES or MIDDLEWARE depending on the django version

get_token - Returns the CSRF token required for a POST form. The token is an alphanumeric value. A new token is created if one is not already set.

In my case, my get_context_data in one of my views was returning return render(self.request, 'es_connection_error.html', {'error':error}); in a try/catch block instead of returning context

Solved by adding the following dependency into pom.xml file :

<dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
        <scope>test</scope>
</dependency>

I had the same problem when and I solved it by using the following annotation :

@EnableAutoConfiguration(exclude = {
        SecurityAutoConfiguration.class
})
public class Application {...}

I think the behavior is the same as what Abhishek explained

The correct way to create a user in Django is to use the create_user function. This will handle the hashing of the password, etc..

from django.contrib.auth.models import User
user = User.objects.create_user(username='john',
                                 email='[email protected]',
                                 password='glass onion')

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"));
}

The HttpParams interface isn't there for specifying query string parameters, it's for specifying runtime behaviour of the HttpClient object.

If you want to pass query string parameters, you need to assemble them on the URL yourself, e.g.

new HttpGet(url + "key1=" + value1 + ...);

Remember to encode the values first (using URLEncoder).

Error message looks like this

Error message => ORA-00001: unique constraint (schema.unique_constraint_name) violated

ORA-00001 occurs when: "a query tries to insert a "duplicate" row in a table". It makes an unique constraint to fail, consequently query fails and row is NOT added to the table."

Solution:

Find all columns used in unique_constraint, for instance column a, column b, column c, column d collectively creates unique_constraint and then find the record from source data which is duplicate, using following queries:

-- to find <<owner of the table>> and <<name of the table>> for unique_constraint

select *
from DBA_CONSTRAINTS
where CONSTRAINT_NAME = '<unique_constraint_name>';

Then use Justin Cave's query (pasted below) to find all columns used in unique_constraint:

  SELECT column_name, position
  FROM all_cons_columns
  WHERE constraint_name = <<name of constraint from the error message>>
   AND owner           = <<owner of the table>>
   AND table_name      = <<name of the table>>

    -- to find duplicates

    select column a, column b, column c, column d
    from table
    group by column a, column b, column c, column d
    having count (<any one column used in constraint > ) > 1;

you can either delete that duplicate record from your source data (which was a select query in my particular case, as I experienced it with "Insert into select") or modify to make it unique or change the constraint.

the first time when you are returning your form make sure you pass the model attribute the form requires which can be done by adding the below code

@RequestMapping(value = "/login", method = RequestMethod.GET)
public String login(Login login)
    return "test";
}

By default the model attribute name is taken as Bean class's name with first lowercase letter

By doing this the form which expects a backing object naming "login" will be made available to it

after the form is submitted you can do the validation by passing your bean object and bindingresult as the method parameters as shown below

@RequestMapping(value = "/login", method = RequestMethod.POST)
public String login(    @ModelAttribute("login") Login login,
                        BindingResult result) 

For gradle users, It works with following steps

1) Stop and Delete tomcat server from Servers Tab in eclipse

2) clean webapp and work directory from tomcat installation , (Reference, How-To: Clear out Tomcat’s cache and fix outdated JSP problems)

$ rm -r /usr/local/AT7028/work/*
$ rm -r /usr/local/AT7028/webapps/WAR_NAME

3) clean and eclipsify project using build tool

$ ./gradlew clean eclipse //fire respective command for mvn users, $ mvn clean package

4) configure a new Tomcat server in eclipse, and run the project again.

I had a similar problem and found that it was because I had a similarly named public property (that should have been private) that only differed in case.

public string PropertyName {get;set;} // actually set propertyName, get propertyName
public string propertyName {get;set;}

should have been

public string PropertyName {get;set;} 
private string propertyName {get;set;}

Render is

def render(request, *args, **kwargs):
    """ Simple wrapper for render_to_response. """
    kwargs['context_instance'] = RequestContext(request)
    return render_to_response(*args, **kwargs)

So there is really no difference between render_to_response except it wraps your context making the template pre-processors work.

Direct to template is a generic view.

There is really no sense in using it here because there is overhead over render_to_response in the form of view function.

In my case the problem was with the nginx config that I've copied from main server to a temporary one with disabling https that is not needed on the second one in the process.

I had to comment out these two lines in the config to make it work again:

# uwsgi_param             UWSGI_SCHEME    https;
# uwsgi_pass_header       X_FORWARDED_PROTO;

The url template tag will pass the parameter as a string and not as a function reference to reverse(). The simplest way to get this working is adding a name to the view:

url(r'^/logout/' , logout_view, name='logout_view')

In django.VERSION (2, 1, 1, 'final', 0) request handler

sock=request._stream.stream.raw._sock
#<socket.socket fd=1236, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, laddr=('192.168.1.111', 8000), raddr=('192.168.1.111', 64725)>
client_ip,port=sock.getpeername()

if you call above code twice,you may got

AttributeError("'_io.BytesIO' object has no attribute 'stream'",)

AttributeError("'LimitedStream' object has no attribute 'raw'")

Below Test Init will also do the job.

[TestInitialize]
public void TestInit()
{
  HttpContext.Current = new HttpContext(new HttpRequest(null, "http://tempuri.org", null), new HttpResponse(null));
  YourControllerToBeTestedController = GetYourToBeTestedController();
}

I would write the code like this:

def search_book(request):
    form = SearchForm(request.POST or None)
    if request.method == "POST" and form.is_valid():
        stitle = form.cleaned_data['title']
        sauthor = form.cleaned_data['author']
        scategory = form.cleaned_data['category']
        return HttpResponseRedirect('/thanks/')
    return render_to_response("books/create.html", {
        "form": form,
    }, context_instance=RequestContext(request))

Pretty much like the documentation.

One other approach that we have taken successfully is to generate the WS client proxy code using wsimport (from Ant, as an Ant task) and specify the wsdlLocation attribute.

<wsimport debug="true" keep="true" verbose="false" target="2.1" sourcedestdir="${generated.client}" wsdl="${src}${wsdl.file}" wsdlLocation="${wsdl.file}">
</wsimport>

Since we run this for a project w/ multiple WSDLs, the script resolves the $(wsdl.file} value dynamically which is set up to be /META-INF/wsdl/YourWebServiceName.wsdl relative to the JavaSource location (or /src, depending on how you have your project set up). During the build proess, the WSDL and XSDs files are copied to this location and packaged in the JAR file. (similar to the solution described by Bhasakar above)

MyApp.jar
|__META-INF
   |__wsdl
      |__YourWebServiceName.wsdl
      |__YourWebServiceName_schema1.xsd
      |__YourWebServiceName_schmea2.xsd

Note: make sure the WSDL files are using relative refrerences to any imported XSDs and not http URLs:

  <types>
    <xsd:schema>
      <xsd:import namespace="http://valueobject.common.services.xyz.com/" schemaLocation="YourWebService_schema1.xsd"/>
    </xsd:schema>
    <xsd:schema>
      <xsd:import namespace="http://exceptions.util.xyz.com/" schemaLocation="YourWebService_schema2.xsd"/>
    </xsd:schema>
  </types>

In the generated code, we find this:

/**
 * This class was generated by the JAX-WS RI.
 * JAX-WS RI 2.2-b05-
 * Generated source version: 2.1
 * 
 */
@WebServiceClient(name = "YourService", targetNamespace = "http://test.webservice.services.xyz.com/", wsdlLocation = "/META-INF/wsdl/YourService.wsdl")
public class YourService_Service
    extends Service
{

    private final static URL YOURWEBSERVICE_WSDL_LOCATION;
    private final static WebServiceException YOURWEBSERVICE_EXCEPTION;
    private final static QName YOURWEBSERVICE_QNAME = new QName("http://test.webservice.services.xyz.com/", "YourService");

    static {
        YOURWEBSERVICE_WSDL_LOCATION = com.xyz.services.webservice.test.YourService_Service.class.getResource("/META-INF/wsdl/YourService.wsdl");
        WebServiceException e = null;
        if (YOURWEBSERVICE_WSDL_LOCATION == null) {
            e = new WebServiceException("Cannot find '/META-INF/wsdl/YourService.wsdl' wsdl. Place the resource correctly in the classpath.");
        }
        YOURWEBSERVICE_EXCEPTION = e;
    }

    public YourService_Service() {
        super(__getWsdlLocation(), YOURWEBSERVICE_QNAME);
    }

    public YourService_Service(URL wsdlLocation, QName serviceName) {
        super(wsdlLocation, serviceName);
    }

    /**
     * 
     * @return
     *     returns YourService
     */
    @WebEndpoint(name = "YourServicePort")
    public YourService getYourServicePort() {
        return super.getPort(new QName("http://test.webservice.services.xyz.com/", "YourServicePort"), YourService.class);
    }

    /**
     * 
     * @param features
     *     A list of {@link javax.xml.ws.WebServiceFeature} to configure on the proxy.  Supported features not in the <code>features</code> parameter will have their default values.
     * @return
     *     returns YourService
     */
    @WebEndpoint(name = "YourServicePort")
    public YourService getYourServicePort(WebServiceFeature... features) {
        return super.getPort(new QName("http://test.webservice.services.xyz.com/", "YourServicePort"), YourService.class, features);
    }

    private static URL __getWsdlLocation() {
        if (YOURWEBSERVICE_EXCEPTION!= null) {
            throw YOURWEBSERVICE_EXCEPTION;
        }
        return YOURWEBSERVICE_WSDL_LOCATION;
    }

}

Perhaps this might help too. It's just a different approach that does not use the "catalog" approach.

The easiest way I found (just I use eval() to convert string gotten from input to tuple to read again for form instance or other place)

This trick works very well

#model.py
class ClassName(models.Model):
    field_name = models.CharField(max_length=100)

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        if self.field_name:
            self.field_name= eval(self.field_name)



#form.py
CHOICES = [('pi', 'PI'), ('ci', 'CI')]

class ClassNameForm(forms.ModelForm):
    field_name = forms.MultipleChoiceField(choices=CHOICES)

    class Meta:
        model = ClassName
        fields = ['field_name',]

Use JsonResponse

from django.http import JsonResponse

Use maven and the plugin jaxws-maven-plugin. this will generate a web service client. Make sure you are setting the xadditionalHeaders to true. This will generate methods with header inputs.

Not sure if this will help in your context...

Can the soap object be cast as a BindingProvider ?

MyWebServiceSoap soap;
MyWebService service = new MyWebService("http://www.google.com");
soap = service.getMyWebServiceSoap();
// set timeouts here
((BindingProvider)soap).getRequestContext().put("com.sun.xml.internal.ws.request.timeout", 10000);
    soap.sendRequestToMyWebService();

On the other hand if you are wanting to set the timeout on the initialization of the MyWebService object then this will not help.

This worked for me when wanting to timeout the individual WebService calls.

BindingProvider.USERNAME_PROPERTY and BindingProvider.PASSWORD_PROPERTY are matching HTTP Basic Authentication mechanism that enable authentication process at the HTTP level and not at the application nor servlet level.

Basically, only the HTTP server will know the username and the password (and eventually application according to HTTP/application server specification, such with Apache/PHP). With Tomcat/Java, add a login config BASIC in your web.xml and appropriate security-constraint/security-roles (roles that will be later associated to users/groups of real users).

<login-config>
    <auth-method>BASIC</auth-method>
    <realm-name>YourRealm</realm-name>
</login-config>

Then, connect the realm at the HTTP server (or application server) level with the appropriate user repository. For tomcat you may look at JAASRealm, JDBCRealm or DataSourceRealm that may suit your needs.

http://tomcat.apache.org/tomcat-6.0-doc/realm-howto.html

Try to do this way

protected override void OnModelCreating(DbModelBuilder modelBuilder) 
{ 
     modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
}

or if you use .net core try it

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<Usuario>().ToTable("Usuario");
}

Replace Usuario for your Entity Name, like a DbSet<<EntityName>> Entities without Plural

This error occurs on the server side when the client closed the socket connection before the response could be returned over the socket. In a web app scenario not all of these are dangerous, since they can be created manually. For example, by quitting the browser before the reponse was retrieved.

Just add attribute runAllManagedModulesForAllRequests="true" to system.webServer\modules in web.config.

This attribute is enabled by default in MVC and Dynamic Data projects.

Just use str.replace(',', '.') - it is both fast and efficient when a single character is to be replaced. And if the comma doesn't exist, it does nothing.

One thing worth adding, though it wasn't asked, is that there is a third option of making the object completely transparent. Consider:

1st <a href="http://example.com" style="display: none;">unseen</a> link.<br />_x000D_
2nd <a href="http://example.com" style="visibility: hidden;">unseen</a> link.<br />_x000D_
3rd <a href="http://example.com" style="opacity: 0;">unseen</a> link.

(Be sure to click "Run code snippet" button above to see the result.)

The difference between 1 and 2 has already been pointed out (namely, 2 still takes up space). However, there is a difference between 2 and 3: in case 3, the mouse will still switch to the hand when hovering over the link, and the user can still click on the link, and Javascript events will still fire on the link. This is usually not the behavior you want (but maybe sometimes it is?).

Another difference is if you select the text, then copy/paste as plain text, you get the following:

1st link.
2nd  link.
3rd unseen link.

In case 3 the text does get copied. Maybe this would be useful for some type of watermarking, or if you wanted to hide a copyright notice that would show up if a carelessly user copy/pasted your content?

I was getting the same error, and running the following code in the command line solved it:

$ heroku config:set BUNDLE_WITHOUT="development:test"

Fastest and general way to do this (line terminators, tabs will be processed as well). Regex powerful facilities don't really needed to solve this problem, but Regex can decrease performance.

                       new string
                           (stringToRemoveWhiteSpaces
                                .Where
                                (
                                    c => !char.IsWhiteSpace(c)
                                )
                                .ToArray<char>()
                           )

OR

                       new string
                           (stringToReplaceWhiteSpacesWithSpace
                                .Select
                                (
                                    c => char.IsWhiteSpace(c) ? ' ' : c
                                )
                                .ToArray<char>()
                           )

According to the manual this should work:

Custom key/value method:

You can include an operator in the first parameter in order to control the comparison:

$this->db->where('name !=', $name);
$this->db->where('id <', $id);
Produces: WHERE name != 'Joe' AND id < 45

Search for $this->db->where(); and look at item #2.

SQL supports qualifying a column by prefixing the reference with either the full table name:

SELECT tbl_names.id, tbl_section.id, name, section
  FROM tbl_names
  JOIN tbl_section ON tbl_section.id = tbl_names.id 

...or a table alias:

SELECT n.id, s.id, n.name, s.section
  FROM tbl_names n
  JOIN tbl_section s ON s.id = n.id 

The table alias is the recommended approach -- why type more than you have to?

Why Do These Queries Look Different?

Secondly, my answers use ANSI-92 JOIN syntax (yours is ANSI-89). While they perform the same, ANSI-89 syntax does not support OUTER joins (RIGHT, LEFT, FULL). ANSI-89 syntax should be considered deprecated, there are many on SO who will not vote for ANSI-89 syntax to reinforce that. For more information, see this question.

The latest way to do that from the documentation is to use the ConnectivityManager to query the active network and determine if it has Internet connectivity.

public boolean hasInternetConnectivity() {
    ConnectivityManager cm =
        (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);

    NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
    return (activeNetwork != null &&
                      activeNetwork.isConnectedOrConnecting());
}

Add these two permissions to your AndroidManifest.xml file:

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

You can use this command line to identify the current container ID (tested with docker 1.9).

awk -F"-|/." '/1:/ {print $3}' /proc/self/cgroup

Then, a little request to Docker API (you can share /var/run/docker.sock) to retrieve all informations.

class Program
{
    static void Main(string[] args)
    {
        Task.Factory.StartNew(() => MyMethod("param value"));
    }

    private static void MyMethod(string p)
    {
        Console.WriteLine(p);
    }
}

There is a new one: http://hayatbiralem.com/blog/2015/05/15/responsive-bootstrap-tabs/

And also Codepen sample available here: http://codepen.io/hayatbiralem/pen/KpzjOL

No needs plugin. It uses just a little css and jquery.

Here's a sample tabs markup:

<ul class="nav nav-tabs nav-tabs-responsive">
    <li class="active">
        <a href="#tab1" data-toggle="tab">
            <span class="text">Tab 1</span>
        </a>
    </li>
    <li class="next">
        <a href="#tab2" data-toggle="tab">
            <span class="text">Tab 2</span>
        </a>
    </li>
    <li>
        <a href="#tab3" data-toggle="tab">
            <span class="text">Tab 3</span>
        </a>
    </li>
    ...
</ul>

.. and jQuery codes are also here:

(function($) {

  'use strict';

  $(document).on('show.bs.tab', '.nav-tabs-responsive [data-toggle="tab"]', function(e) {
    var $target = $(e.target);
    var $tabs = $target.closest('.nav-tabs-responsive');
    var $current = $target.closest('li');
    var $parent = $current.closest('li.dropdown');
        $current = $parent.length > 0 ? $parent : $current;
    var $next = $current.next();
    var $prev = $current.prev();
    var updateDropdownMenu = function($el, position){
      $el
        .find('.dropdown-menu')
        .removeClass('pull-xs-left pull-xs-center pull-xs-right')
        .addClass( 'pull-xs-' + position );
    };

    $tabs.find('>li').removeClass('next prev');
    $prev.addClass('prev');
    $next.addClass('next');

    updateDropdownMenu( $prev, 'left' );
    updateDropdownMenu( $current, 'center' );
    updateDropdownMenu( $next, 'right' );
  });

})(jQuery);

One potential downside with setting the field value to "" (empty string) in the constructor is if the field is an optional field and is left unedited. Unless you do some massaging before posting your form, the field will be persisted to your data storage as an empty string instead of NULL.

This alternative will avoid empty strings:

constructor(props) {
    super(props);
    this.state = {
        name: null
    }
}

... 

<input name="name" type="text" value={this.state.name || ''}/>

Have you tried editing the history file directly:

~/.bash_history

You can use as keyword to refer a collection under a ng-repeat element:

<table>
    <tr ng-repeat="task in tasks | filter:category | filter:query as res">
        <td>{{task.id}}</td>
        <td>{{task.description}}</td>
    </tr>
    <tr ng-if="res.length === 0">
        <td colspan="2">no results</td>
    </tr>
</table>

(similar as Gustavo said, but additionally: )

For any previously search, you can do simply:

:%s///gn

A pattern is not needed, because it is already in the search-register (@/).

"%" - do s/ in the whole file
"g" - search global (with multiple hits in one line)
"n" - prevents any replacement of s/ -- nothing is deleted! nothing must be undone!
(see: :help s_flag for more informations)

(This way, it works perfectly with "Search for visually selected text", as described in vim-wikia tip171)

It might be an old question, but as a one liner to get the name of the month when we know the indices, I used

String month = new DateFormatSymbols().getMonths()[monthNumber - 1];

or for short names

String month = new DateFormatSymbols().getShortMonths()[monthNumber - 1];

Please be aware that your monthNumber starts counting from 1 while any of the methods above returns an array so you need to start counting from 0.

You can do:

foreach ($arr as $key => $value) {
 echo $key;
}

As described in PHP docs.

you can try with :

return 0;

that work in case of stop process.

In order to simply check the string that it contains only ALPHABETS use the following code :

if (text.matches("[a-zA-Z]+"){
   // your operations
}

In order to simply check the string that it contains only NUMBER use the following code :

if (text.matches("[0-9]+"){
   // your operations
}

Hope this will help to someone!

Use LayoutBuilder and Get the output you want

Wrap the SingleChildScrollView with LayoutBuilder and implement the Builder function.

we can use a LayoutBuilder to get the box contains or the amount of space available.

LayoutBuilder(
    builder: (BuildContext context, BoxConstraints constraints){
      return SingleChildScrollView(
        child: Stack(
          children: <Widget>[
            Container(
              height: constraints.maxHeight,
            ),
            topTitle(context),
            middleView(context),
            bottomView(context),
          ],
        ),
      );
    }
)

I don't know about sliding the space bar. I have a small box on the left of my keyboard that indicates which language is selected ( when english is selected it shows the words EN with a small microphone on top. Being that I also have spanish as one of my languages, I just tap that button and it swithces back and forth from spanish to english.

Here the XAML Version

<Window.Background>
    <ImageBrush>
        <ImageBrush.ImageSource>
            <BitmapImage UriSource="//your source .."/>

    </ImageBrush>
</Window.Background>

I got that error because I declared a variable and later wanted to
changed it's value using ngAfterViewInit

export class SomeComponent {

    header: string;

}

to fix that I switched from

ngAfterViewInit() { 

    // change variable value here...
}

to

ngAfterContentInit() {

    // change variable value here...
}

I use Google Docs embeddable PDF viewer. The docs don't have to be uploaded to Google Docs, but they do have to be available online.

I use HttpWebRequest to GET from the web service, which returns me a JSON string. It looks something like this for a GET:

// Returns JSON string
string GET(string url) 
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    try {
        WebResponse response = request.GetResponse();
        using (Stream responseStream = response.GetResponseStream()) {
            StreamReader reader = new StreamReader(responseStream, System.Text.Encoding.UTF8);
            return reader.ReadToEnd();
        }
    }
    catch (WebException ex) {
        WebResponse errorResponse = ex.Response;
        using (Stream responseStream = errorResponse.GetResponseStream())
        {
            StreamReader reader = new StreamReader(responseStream, System.Text.Encoding.GetEncoding("utf-8"));
            String errorText = reader.ReadToEnd();
            // log errorText
        }
        throw;
    }
}

I then use JSON.Net to dynamically parse the string. Alternatively, you can generate the C# class statically from sample JSON output using this codeplex tool: http://jsonclassgenerator.codeplex.com/

POST looks like this:

// POST a JSON string
void POST(string url, string jsonContent) 
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    request.Method = "POST";

    System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
    Byte[] byteArray = encoding.GetBytes(jsonContent);

    request.ContentLength = byteArray.Length;
    request.ContentType = @"application/json";

    using (Stream dataStream = request.GetRequestStream()) {
        dataStream.Write(byteArray, 0, byteArray.Length);
    }
    long length = 0;
    try {
        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) {
            length = response.ContentLength;
        }
    }
    catch (WebException ex) {
        // Log exception and throw as for GET example above
    }
}

I use code like this in automated tests of our web service.

In order to completely remove pip, I believe you have to delete its files from all Python versions on your computer. For me, they are here:

cd /Library/Frameworks/Python.framework/Versions/Current/bin/
cd /Library/Frameworks/Python.framework/Versions/3.3/bin/

You may need to remove the files or the directories located at these file-paths (and more, depending on the number of versions of Python you have installed).

Edit: to find all versions of pip on your machine, use: find / -name pip 2>/dev/null, which starts at its highest level (hence the /) and hides all error messages (that's what 2>/dev/null does). This is my output:

$ find / -name pip 2>/dev/null
/Library/Frameworks/Python.framework/Versions/2.7/bin/pip
/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pip
/Library/Frameworks/Python.framework/Versions/3.3/bin/pip
/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages/pip
/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/pip
/Library/Frameworks/Python.framework/Versions/7.1/bin/pip
/Library/Frameworks/Python.framework/Versions/7.1/lib/python2.7/site-packages/pip-1.4.1-py2.7.egg/pip

If you need to center horizontally and vertically too:

left: 50%;
top: 50%;
transform: translate(-50%, -50%);

There is no way to recursively search through the classpath. You need to know the Full pathname of a resource to be able to retrieve it in this way. The resource may be in a directory in the file system or in a jar file so it is not as simple as performing a directory listing of "the classpath". You will need to provide the full path of the resource e.g. '/com/mypath/bla.xml'.

For your second question, getResource will return the first resource that matches the given resource name. The order that the class path is searched is given in the javadoc for getResource.

Apache Wink has OrderedJSONObject. It keeps the order while parsing the String.

Think of it as just another safety level. You can design your table without foreign key relationships - perfectly valid - and ensure existence of associated entities entirely on the business layer. However, foreign keys are considered good design practice because they add another constraint level in case something messes up on the business layer. Same goes for field size limitation and not using varchar MAX.

This is fixed in npm 7. See npm/cli#PR169

First check if you have configured JDK correctly:

• Go to File->Project Structure -> SDKs
• your JDK home path should be something like this: /Library/Java/JavaVirtualMachine/jdk.1.7.0_79.jdk/Contents/Home
• Hit Apply and then OK

Secondly check if you have provided in path in Library's section

• Go to File->Project Structure -> Libraries
• Hit the + button
• Add the path to your src folder
• Hit Apply and then OK

This should fix the problem

if you want to get the whole period:

    from sqlalchemy import and_, func

    query = DBSession.query(User).filter(and_(func.date(User.birthday) >= '1985-01-17'),\
                                              func.date(User.birthday) <= '1988-01-17'))

That means range: 1985-01-17 00:00 - 1988-01-17 23:59

From developer.mozilla.org String.prototype.endsWith()

Summary

The endsWith() method determines whether a string ends with the characters of another string, returning true or false as appropriate.

Syntax

str.endsWith(searchString [, position]);

Parameters

• searchString : The characters to be searched for at the end of this string.

• position : Search within this string as if this string were only this long; defaults to this string's actual length, clamped within the range established by this string's length.

Description

This method lets you determine whether or not a string ends with another string.

Examples

var str = "To be, or not to be, that is the question.";

alert( str.endsWith("question.") );  // true
alert( str.endsWith("to be") );      // false
alert( str.endsWith("to be", 19) );  // true

When you're using Data Type: int you can select the row which you want to get autoincremented and go to the column properties tag. There you can set the identity to 'yes'. The starting value for autoincrement can also be edited there. Hope I could help ;)

The tutorial you saw was telling you how to exit nano editor. By typing Ctrl+X nano exits and if your file needs change you will be prompted to save the changes in which case to save you should press Y and then enter to save changes in the same file you open.

If you are not using any gui and you just want to leave the shell the command is Ctrl+D.

Regarding tutorial, The Linux Documentation Project would be a good place to start. If you like books I would recommend by far any book you want from O'Reilly. They have nice cd bookshelfs with good compilation for any linux sysadmin, and without much effort you can find many places where those html bookshelfs are available to read online.

In Ruby 1.9.2 and above they added a .to_date function to DateTime:

http://ruby-doc.org/stdlib-1.9.2/libdoc/date/rdoc/DateTime.html#method-i-to_date

This instance method doesn't appear to be present in earlier versions like 1.8.7.

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;

This will do the trick, similar with Tiago's solution, return "source" table as well.

select [First name], [Last name], max(_tabloc) as _tabloc
from (
  select [First Name], [Last name], 't1' as _tabloc from table1
  union all
  select [First name], [Last name], 't2' as _tabloc from table2
) v
group by [Fist Name], [Last name]
having count(1)=1

result will contain differences between tables, in column _tabloc you will have table reference.

It sounds like the populate method is what your looking for. First make small change to your post schema:

var postSchema = new Schema({
    name: String,
    postedBy: {type: mongoose.Schema.Types.ObjectId, ref: 'User'},
    dateCreated: Date,
    comments: [{body:"string", by: mongoose.Schema.Types.ObjectId}],
});

Then make your model:

var Post = mongoose.model('Post', postSchema);

Then, when you make your query, you can populate references like this:

Post.findOne({_id: 123})
.populate('postedBy')
.exec(function(err, post) {
    // do stuff with post
});

According to this page, it's ∞.

Selecting verbose fixed it for me

For those saying that the answer of @kuester2000 does not work, please be aware that HTTP requests, first try to find the host IP with a DNS request and then makes the actual HTTP request to the server, so you may also need to set a timeout for the DNS request.

If your code worked without the timeout for the DNS request it's because you are able to reach a DNS server or you are hitting the Android DNS cache. By the way you can clear this cache by restarting the device.

This code extends the original answer to include a manual DNS lookup with a custom timeout:

//Our objective
String sURL = "http://www.google.com/";
int DNSTimeout = 1000;
int HTTPTimeout = 2000;

//Get the IP of the Host
URL url= null;
try {
     url = ResolveHostIP(sURL,DNSTimeout);
} catch (MalformedURLException e) {
    Log.d("INFO",e.getMessage());
}

if(url==null){
    //the DNS lookup timed out or failed.
}

//Build the request parameters
HttpParams params = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(params, HTTPTimeout);
HttpConnectionParams.setSoTimeout(params, HTTPTimeout);

DefaultHttpClient client = new DefaultHttpClient(params);

HttpResponse httpResponse;
String text;
try {
    //Execute the request (here it blocks the execution until finished or a timeout)
    httpResponse = client.execute(new HttpGet(url.toString()));
} catch (IOException e) {
    //If you hit this probably the connection timed out
    Log.d("INFO",e.getMessage());
}

//If you get here everything went OK so check response code, body or whatever

Used method:

//Run the DNS lookup manually to be able to time it out.
public static URL ResolveHostIP (String sURL, int timeout) throws MalformedURLException {
    URL url= new URL(sURL);
    //Resolve the host IP on a new thread
    DNSResolver dnsRes = new DNSResolver(url.getHost());
    Thread t = new Thread(dnsRes);
    t.start();
    //Join the thread for some time
    try {
        t.join(timeout);
    } catch (InterruptedException e) {
        Log.d("DEBUG", "DNS lookup interrupted");
        return null;
    }

    //get the IP of the host
    InetAddress inetAddr = dnsRes.get();
    if(inetAddr==null) {
        Log.d("DEBUG", "DNS timed out.");
        return null;
    }

    //rebuild the URL with the IP and return it
    Log.d("DEBUG", "DNS solved.");
    return new URL(url.getProtocol(),inetAddr.getHostAddress(),url.getPort(),url.getFile());
}   

This class is from this blog post. Go and check the remarks if you will use it.

public static class DNSResolver implements Runnable {
    private String domain;
    private InetAddress inetAddr;

    public DNSResolver(String domain) {
        this.domain = domain;
    }

    public void run() {
        try {
            InetAddress addr = InetAddress.getByName(domain);
            set(addr);
        } catch (UnknownHostException e) {
        }
    }

    public synchronized void set(InetAddress inetAddr) {
        this.inetAddr = inetAddr;
    }
    public synchronized InetAddress get() {
        return inetAddr;
    }
}

The pageContext is an implicit object available in JSPs. The EL documentation says

The context for the JSP page. Provides access to various objects including:
servletContext: ...
session: ...
request: ...
response: ...

Thus this expression will get the current HttpServletRequest object and get the context path for the current request and append /JSPAddress.jsp to it to create a link (that will work even if the context-path this resource is accessed at changes).

The primary purpose of this expression would be to keep your links 'relative' to the application context and insulate them from changes to the application path.

For example, if your JSP (named thisJSP.jsp) is accessed at http://myhost.com/myWebApp/thisJSP.jsp, thecontext path will be myWebApp. Thus, the link href generated will be /myWebApp/JSPAddress.jsp.

If someday, you decide to deploy the JSP on another server with the context-path of corpWebApp, the href generated for the link will automatically change to /corpWebApp/JSPAddress.jsp without any work on your part.

XSD : XML Schema Definition.

XML : eXtensible Markup Language.

WSDL : Web Service Definition Language.

I am not going to answer in technical terms. I am aiming this explanation at beginners.

It is not easy to communicate between two different applications that are developed using two different technologies. For example, a company in Chicago might develop a web application using Java and another company in New York might develop an application in C# and when these two companies decided to share information then XML comes into picture. It helps to store and transport data between two different applications that are developed using different technologies. Note: It is not limited to a programming language, please do research on the information transportation between two different apps.

XSD is a schema definition. By that what I mean is, it is telling users to develop their XML in such a schema. Please see below images, and please watch closely with "load-on-startup" element and its type which is integer. In the XSD image you can see it is meant to be integer value for the "load-on-startup" and hence when user created his/her XML they passed an int value to that particular element. As a reminder, XSD is a schema and style whereas XML is a form to communicate with another application or system. One has to see XSD and create XML in such a way or else it won't communicate with another application or system which has been developed with a different technology. A company in Chicago provides a XSD template for a company in Texas to write or generate their XML in the given XSD format. If the company in Texas failed to adhere with those rules or schema mentioned in XSD then it is impossible to expect correct information from the company in Chicago. There is so much to do after the above said story, which an amateur or newbie have to know while coding for some thing like I said above. If you really want to know what happens later then it is better to sit with senior software engineers who actually developed web services. Next comes WSDL, please follow the images and try to figure out where the WSDL will fit in.

***************========Below is partial XML image ==========***************

***************========Below is partial XSD image ==========***************

***************========Below is the partial WSDL image =======*************

I had to create a sample WSDL for a web service called Book. Note, it is an XSD but you have to call it WSDL (Web Service Definition Language) because it is very specific for Web Services. The above WSDL (or in other words XSD) is created for a class called Book.java and it has created a SOAP service. How the SOAP web service created it is a different topic. One has to write a Java class and before executing it create as a web service the user has to make sure Axis2 API is installed and Tomcat to host web service is in place.

As a servicer (the one who allows others (clients) to access information or data from their systems ) actually gives the client (the one who needs to use servicer information or data) complete access to data through a Web Service, because no company on the earth willing to expose their Database for outsiders. Like my company, decided to give some information about products via Web Services, hence we had to create XSD template and pass-on to few of our clients who wants to work with us. They have to write some code to make complete use of the given XSD and make Web Service calls to fetch data from servicer and convert data returned into their suitable requirement and then display or publish data or information about the product on their website. A simple example would be FLIGHT Ticket booking. An airline will let third parties to use flight data on their site for ticket sales. But again there is much more to it, it is just not letting third party flight ticket agent to sell tickets, there will be synchronize and security in place. If there is no sync then there is 100 % chances more than 1 customer might buy same flight ticket from various sources.

I am hoping experts will contribute to my answer. It is really hard for newbie or novice to understand XML, XSD and then to work on Web Services.

Rails4 has some added datatypes for Postgres.

For example, railscast #400 names two of them:

Rails 4 has support for native datatypes in Postgres and we’ll show two of these here, although a lot more are supported: array and hstore. We can store arrays in a string-type column and specify the type for hstore.

Besides, you can also use cidr, inet and macaddr. For more information:

https://blog.engineyard.com/2013/new-in-rails-4

For Windows Server 2012, the solution is very similar to faester's (see above). From the Server Manager, click on Add roles and features, select the appropriate server, then select Features. Under .NET Framework 4.5 Features, you'll see WCF Services, and under that, you'll find HTTP Activation.

You need Set with objects:

 Set rng = Sheet8.Range("A12")

Sheet8 is fine.

 Sheet1.[a1]

If you're using Bootstrap 3, you can use the Glyphicons.

"most convenient block of data" probably refers to the width (in bits) of the WORD, in correspondance to the system bus width, or whatever underlying "bandwidth" is available. On a 16 bit system, with WORD being defined as 16 bits wide, moving data around in chunks the size of a WORD will be the most efficient way. (On hardware or "system" level.)

With Java being more or less platform independant, it just defines a "WORD" as the next size from a "BYTE", meaning "full bandwidth". I guess any platform that's able to run Java will use 32 bits for a WORD.

I've just checked

$scope.$parent.someProperty

works for me.

and it will be

{{$parent.someProperty}}

for the view.

Some browser may block popup created by window.open(url, "_blank");. An alternative is to create a link and click on it.

...

  constructor(@Inject(DOCUMENT) private document: Document) {}
...

  openNewWindow(): void {
    const link = this.document.createElement('a');
    link.target = '_blank';
    link.href = 'http://www.your-url.com';
    link.click();
    link.remove();
  }

If the command that you are trying to execute fails, it would write the output onto the error stream and would then be printed out to the console.

To avoid it, you must redirect the error stream:

result=$(ls -l something_that_does_not_exist 2>&1)

As you run the container, a directory on your host is created and mounted into the container. You can find out what directory this is with

$ docker inspect --format "{{ .Volumes }}" <ID>
map[/export:/var/lib/docker/vfs/dir/<VOLUME ID...>]

If you want to mount a directory from your host inside your container, you have to use the -v parameter and specify the directory. In your case this would be:

docker run -v /export:/export data

SO you would use the hosts folder inside your container.

In order to verify a client certificate is being sent to the server, you need to analyze the output from the combination of the -state and -debug flags.

First as a baseline, try running

$ openssl s_client -connect host:443 -state -debug

You'll get a ton of output, but the lines we are interested in look like this:

SSL_connect:SSLv3 read server done A
write to 0x211efb0 [0x21ced50] (12 bytes => 12 (0xC))
0000 - 16 03 01 00 07 0b 00 00-03                        .........
000c - <SPACES/NULS>
SSL_connect:SSLv3 write client certificate A

What's happening here:

• The -state flag is responsible for displaying the end of the previous section:

  SSL_connect:SSLv3 read server done A  
  

  This is only important for helping you find your place in the output.

• Then the -debug flag is showing the raw bytes being sent in the next step:

  write to 0x211efb0 [0x21ced50] (12 bytes => 12 (0xC))
  0000 - 16 03 01 00 07 0b 00 00-03                        .........
  000c - <SPACES/NULS>
  

• Finally, the -state flag is once again reporting the result of the step that -debug just echoed:

  SSL_connect:SSLv3 write client certificate A
  

So in other words: s_client finished reading data sent from the server, and sent 12 bytes to the server as (what I assume is) a "no client certificate" message.

If you repeat the test, but this time include the -cert and -key flags like this:

$ openssl s_client -connect host:443 \
   -cert cert_and_key.pem \
   -key cert_and_key.pem  \
   -state -debug

your output between the "read server done" line and the "write client certificate" line will be much longer, representing the binary form of your client certificate:

SSL_connect:SSLv3 read server done A
write to 0x7bd970 [0x86d890] (1576 bytes => 1576 (0x628))
0000 - 16 03 01 06 23 0b 00 06-1f 00 06 1c 00 06 19 31   ....#..........1
(*SNIP*)
0620 - 95 ca 5e f4 2f 6c 43 11-                          ..^%/lC.
SSL_connect:SSLv3 write client certificate A

The 1576 bytes is an excellent indication on its own that the cert was transmitted, but on top of that, the right-hand column will show parts of the certificate that are human-readable: You should be able to recognize the CN and issuer strings of your cert in there.

In addition to already suggested p and puts — well, actually in most cases you do can write logger.info "blah" just as you suggested yourself. It works in console too, not only in server mode.

But if all you want is console debugging, puts and p are much shorter to write, anyway.

I think you set the marquee width related to 5 images total width. It works fine

ex: <marquee style="width:700px"></marquee>

Use this line to your Build gradle app

repositories {
    maven { url "http://jcenter.bintray.com" }}

I found the similar problem and found the solution and i have blogged about how to upload the file using JSP , In that example i have used the absolute path. Note that if you want to route to some other URL based location you can put a ESB like WSO2 ESB

you can use this after "preventDefault" method

//Here evt.target return default event (eg : defult url etc)

var defaultEvent=evt.target;

//Here we save default event ..

if("true")
{
//activate default event..
location.href(defaultEvent);
}

This worked for me:

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

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

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

}

I wanted to set the width of the first column of the table, and I found this worked (in FF7) - the first column is 50px wide:

#MyTable>thead>tr>th:first-child { width:50px;}

where my markup was

<table id="MyTable">
 <thead>
  <tr>
   <th scope="col">Col1</th>
   <th scope="col">Col2</th>
  </tr>
 </thead>
 <tbody>
   ...
 </tbody>
</table>

If that is really all the batch file is doing, remove the cmd /K and add PAUSE.

start /B /LOW /WAIT make package
PAUSE

Then, just point your shortcut to "My Batch File.bat"...no need to run it with CMD /K.

UPDATE

Ah, some new info...you're trying to do it from a pinned shortcut on the taskbar.

I found this, Adding Batch Files to Windows 7 Taskbar like the Vista/XP Quick Launch, with the relevant part below.

1. First, pin a shortcut for CMD.EXE to the taskbar by hitting the start button, then type "cmd" in the search box, right-click the result and chose "Pin to Taskbar".
2. Right-click the shortcut on the taskbar.
3. You will see a list that includes "Command Prompt" and "Unpin this program from the taskbar".
4. Right-click the icon for CMD.EXE and select Properties.
5. In the box for Target, go to the end of "%SystemRoot%\system32\cmd.exe" and type " /C " and the path and name of the batch file.

For your purposes, you can either:

1. Use /C and put a PAUSE at the end of your batch file.

   OR

2. Change the command line to use /K and remove the PAUSE from your batch file.

The simplest way: run git push -u origin feature/123-sandbox-tests once. That pushes the branch the way you're used to doing it and also sets the upstream tracking info in your local config. After that, you can just git push to push tracked branches to their upstream remote(s).

You can also do this in the config yourself by setting branch.<branch name>.merge to the remote branch name (in your case the same as the local name) and optionally, branch.<branch name>.remote to the name of the remote you want to push to (defaults to origin). If you look in your config, there's most likely already one of these set for master, so you can follow that example.

Finally, make sure you consider the push.default setting. It defaults to "matching", which can have undesired and unexpected results. Most people I know find "upstream" more intuitive, which pushes only the current branch.

Details on each of these settings can be found in the git-config man page.

On second thought, on re-reading your question, I think you know all this. I think what you're actually looking for doesn't exist. How about a bash function something like (untested):

function pushCurrent {
  git config push.default upstream
  git push
  git config push.default matching
}

This worked for me:

mycomponent.component.ts:

action(event): void {
  event.stopPropagation();
}

mycomponent.component.html:

<button mat-icon-button (click)="action($event);false">Click me !<button/>

Another alternative is to use the ufunc.at. This method applies in-place a desired operation at specified indices. We can get the bin position for each datapoint using the searchsorted method. Then we can use at to increment by 1 the position of histogram at the index given by bin_indexes, every time we encounter an index at bin_indexes.

np.random.seed(1)
data = np.random.random(100) * 100
bins = np.linspace(0, 100, 10)

histogram = np.zeros_like(bins)

bin_indexes = np.searchsorted(bins, data)
np.add.at(histogram, bin_indexes, 1)

I came across the same nagging error, which I realized has something to do with a cool feature PyCharm automatically detects...just add the @staticmethod decorator, and it will automatically remove that error where the method is used

Also ran into this error message, but the root cause was of a different flavor from those referenced in the other answers here.

Generic answer: Make sure that once hibernate loads an entity, no code changes the primary key value in that object in any way. When hibernate flushes all changes back to the database, it throws this exception because the primary key changed. If you don't do it explicitly, look for places where this may happen unintentionally, perhaps on related entities that only have LAZY loading configured.

In my case, I am using a mapping framework (MapStruct) to update an entity. In the process, also other referenced entities were being updates as mapping frameworks tend to do that by default. I was later replacing the original entity with new one (in DB terms, changed the value of the foreign key to reference a different row in the related table), the primary key of the previously-referenced entity was already updated, and hibernate attempted to persist this update on flush.

I use the following method in my JavaFX applications.

newWindowButton.setOnMouseClicked((event) -> {
    try {
        FXMLLoader fxmlLoader = new FXMLLoader();
        fxmlLoader.setLocation(getClass().getResource("NewWindow.fxml"));
        /* 
         * if "fx:controller" is not set in fxml
         * fxmlLoader.setController(NewWindowController);
         */
        Scene scene = new Scene(fxmlLoader.load(), 600, 400);
        Stage stage = new Stage();
        stage.setTitle("New Window");
        stage.setScene(scene);
        stage.show();
    } catch (IOException e) {
        Logger logger = Logger.getLogger(getClass().getName());
        logger.log(Level.SEVERE, "Failed to create new Window.", e);
    }
});

Something to note, when setting the scroll position, make sure you do it in the correct scope. For example, if you're using the scroll position in multiple functions, you would want to set it outside of these functions.

$(document).ready(function() {
    var tempScrollTop = $(window).scrollTop();
    function example() {
        console.log(tempScrollTop);
    };

});

You can use the model from the react-bootstrap from link and it's basically a function based

function Example() {
  const [show, setShow] = useState(false);
  const handleClose = () => setShow(false);
  const handleShow = () => setShow(true);
  return (
    <>
      <Button variant="primary" onClick={handleShow}>
        Launch demo modal
      </Button>

      <Modal show={show} onHide={handleClose} animation={false}>
        <Modal.Header closeButton>
          <Modal.Title>Modal heading</Modal.Title>
        </Modal.Header>
        <Modal.Body>Woohoo, you're reading this text in a modal!</Modal.Body>
        <Modal.Footer>
          <Button variant="secondary" onClick={handleClose}>
            Close
          </Button>
          <Button variant="primary" onClick={handleClose}>
            Save Changes
          </Button>
        </Modal.Footer>
      </Modal>
    </>
  );
}

and You can convert it into the class component

import React, { Component } from "react";
import { Button, Modal } from "react-bootstrap";


export default class exampleextends Component {
  constructor(props) {
    super(props);
    this.state = {
      show: false,
      close: false,
    };
  } 
  render() {
    return (
      <div>
        <Button
          variant="none"
          onClick={() => this.setState({ show: true })}
        >
          Choose Profile
        </Button>
        <Modal
          show={this.state.show}
          animation={true}
          size="md" className="" shadow-lg border">
          <Modal.Header className="bg-danger text-white text-center py-1">
            <Modal.Title className="text-center">
              <h5>Delete</h5>
            </Modal.Title>
          </Modal.Header>
          <Modal.Body className="py-0 border">
            body   
          </Modal.Body>
<Modal.Footer className="py-1 d-flex justify-content-center">
              <div>
                <Button
                  variant="outline-dark" onClick={() => this.setState({ show: false })}>Cancel</Button>
              </div>
              <div>
                <Button variant="outline-danger" className="mx-2 px-3">Delete</Button>
              </div>
            </Modal.Footer>
        </Modal>
      </div>
    );
  }
}

If you are using SE linux, set it to permissive mode by editing /etc/selinux/config and changing SELINUX=enforcing to SELINUX=permissive

The solution is actually a lot easier than any of the other suggestions:

std::wstring stemp = std::wstring(s.begin(), s.end());
LPCWSTR sw = stemp.c_str();

Best of all, it's platform independent.

I found the answer... or at least, the easiest answer (if there are multiple). When I installed the printer, I renamed it to "ICS Label Printer". Here's how to change the options to allow pass-through ZPL commands:

1. Right-click on the "ICS Label Printer" and choose "Properties".
2. On the "General" tab, click on the "Printing Preferences..." button.
3. On the "Advanced Setup" tab, click on the "Other" button.
4. Make sure there is a check in the box labeled "Enable Passthrough Mode".
5. Make sure the "Start sequence:" is "${".
6. Make sure the "End sequence:" is "}$".
7. Click on the "Close" button.
8. Click on the "OK" button.
9. Click on the "OK" button.

In my code, I just have to add "${" to the beginning of my ZPL and "}$" to the end and print it as plain text. This is with the "Windows driver for ZDesigner LP 2844-Z printer Version 2.6.42 (Build 2382)". Works like a charm!

As of 2020, using ContentResult is still the right approach as proposed above, but the usage is as follows:

return new System.Web.Mvc.ContentResult
{
    Content = "Hi there! ?",
    ContentType = "text/plain; charset=utf-8"
}

In this situation you can use ISNULL() function instead of CASE expression

ISNULL(B.[STAT], C.[EVENT DATE]+10) AS [DATE]

A minor update to this: a sender should never set the Return-Path: header. There's no such thing as a Return-Path: header for a message in transit. That header is set by the MTA that makes final delivery, and is generally set to the value of the 5321.From unless the local system needs some kind of quirky routing.

It's a common misunderstanding because users rarely see an email without a Return-Path: header in their mailboxes. This is because they always see delivered messages, but an MTA should never see a Return-Path: header on a message in transit. See http://tools.ietf.org/html/rfc5321#section-4.4

I'll share my very simple code for sample purpose. Hope it will help someone like me searching for quick code reference. My goal was to receive rsa signature from backend, then validate against input string using public key and store locally for future periodic verifications. Here is main part used for signature verification:

        ...
        var signature = Get(url); // base64_encoded signature received from server
        var inputtext= "inputtext"; // this is main text signature was created for
        bool result = VerifySignature(inputtext, signature);
        ...

    private bool VerifySignature(string input, string signature)
    {
        var result = false;
        using (var cps=new RSACryptoServiceProvider())
        {
            // converting input and signature to Bytes Arrays to pass to VerifyData rsa method to verify inputtext was signed using privatekey corresponding to public key we have below
            byte[] inputtextBytes = Encoding.UTF8.GetBytes(input);
            byte[] signatureBytes  = Convert.FromBase64String(signature);

            cps.FromXmlString("<RSAKeyValue><Modulus>....</Modulus><Exponent>....</Exponent></RSAKeyValue>"); // xml formatted publickey
            result = cps.VerifyData(inputtextBytes , new SHA1CryptoServiceProvider(), signatureBytes  );
        }

        return result;
    }

On server where your admin run kafka find kafka-console-consumer.sh by command find . -name kafka-console-consumer.sh then go to that directory and run for read message from your topic

./kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning --max-messages 10

note that in topic may be many messages in that case I use --max-messages key

Yes, 4,2 means "4 digits total, 2 of which are after the decimal place". That translates to a number in the format of 00.00. Beyond that, you'll have to show us your SQL query. PHP won't translate 3.80 into 99.99 without good reason. Perhaps you've misaligned your fields/values in the query and are trying to insert a larger number that belongs in another field.

In the example in the code you have posted there is, in fact, no point in catching the exception as there is nothing done on the catch it is just re-thown, in fact it does more harm than good as the call stack is lost.

You would, however catch an exception to do some logic (for example closing sql connection of file lock, or just some logging) in the event of an exception the throw it back to the calling code to deal with. This would be more common in a business layer than front end code as you may want the coder implementing your business layer to handle the exception.

To re-iterate though the There is NO point in catching the exception in the example you posted. DON'T do it like that!

This is the solution I came up with if anyone is interested.

https://kellyschronicles.wordpress.com/2017/12/16/dynamic-predicate-for-a-linq-query/

First we identify the single element type we need to use ( Of TRow As DataRow) and then identify the “source” we are using and tie the identifier to that source ((source As TypedTableBase(Of TRow)). Then we must specify the predicate, or the WHERE clause that is going to be passed (predicate As Func(Of TRow, Boolean)) which will either be returned as true or false. Then we identify how we want the returned information ordered (OrderByField As String). Our function will then return a EnumerableRowCollection(Of TRow), our collection of datarows that have met the conditions of our predicate(EnumerableRowCollection(Of TRow)). This is a basic example. Of course you must make sure your order field doesn’t contain nulls, or have handled that situation properly and make sure your column names (if you are using a strongly typed datasource never mind this, it will rename the columns for you) are standard.

As mentioned in the error, the official manual and the comments:

Replace

public function TSStatus($host, $queryPort)

with

public function __construct($host, $queryPort)

I had a similar issue on 16.04 VPS Digital Ocean. If you are changing crontabs, make sure to run

Here I came up with universal method to navigate from any place to root.

1. You create a new Class file with this class, so that it's accessible from anywhere in your project:

   import UIKit
   
   class SharedControllers
   {
       static func navigateToRoot(viewController: UIViewController)
       {
           var nc = viewController.navigationController
   
           // If this is a normal view with NavigationController, then we just pop to root.
           if nc != nil
           {
               nc?.popToRootViewControllerAnimated(true)
               return
           }
   
           // Most likely we are in Modal view, so we will need to search for a view with NavigationController.
           let vc = viewController.presentingViewController
   
           if nc == nil
           {
               nc = viewController.presentingViewController?.navigationController
           }
   
           if nc == nil
           {
               nc = viewController.parentViewController?.navigationController
           }
   
           if vc is UINavigationController && nc == nil
           {
               nc = vc as? UINavigationController
           }
   
           if nc != nil
           {
               viewController.dismissViewControllerAnimated(false, completion:
                   {
                       nc?.popToRootViewControllerAnimated(true)
               })
           }
       }
   }
   

2. Usage from anywhere in your project:

   {
       ...
       SharedControllers.navigateToRoot(self)
       ...
   }
   

Using LINQ to xml if you are using framework 3.5:

using System.Xml.Linq;

XDocument xmlFile = XDocument.Load("books.xml"); 

var query = from c in xmlFile.Elements("catalog").Elements("book")    
            select c; 

foreach (XElement book in query) 
{
   book.Attribute("attr1").Value = "MyNewValue";
}

xmlFile.Save("books.xml");

To extract the audio stream without re-encoding:

ffmpeg -i input-video.avi -vn -acodec copy output-audio.aac

• -vn is no video.
• -acodec copy says use the same audio stream that's already in there.

Read the output to see what codec it is, to set the right filename extension.

Its best practice to have TOP 1 1 always.

What if I use SELECT 1 -> If condition matches more than one record then your query will fetch all the columns records and returns 1.

What if I use SELECT TOP 1 1 -> If condition matches more than one record also, it will just fetch the existence of any row (with a self 1-valued column) and returns 1.

IF EXISTS (SELECT TOP 1 1 FROM tblGLUserAccess WHERE GLUserName ='xxxxxxxx') 
BEGIN
   SELECT 1 
END
ELSE
BEGIN
    SELECT 2
END

If this is for a Windows Runtime application, then you have to add the self-signed certificate to the project and reference it in the appxmanifest.

The docs are here: http://msdn.microsoft.com/en-us/library/windows/apps/hh465031.aspx

Same thing if it's from a CA that's not trusted (like a private CA that the machine itself doesn't trust) -- you need to get the CA's public cert, add it as content to the app then add it to the manifest.

Once that's done, the app will see it as a correctly signed cert.

System.Diagnostics.Process process = new System.Diagnostics.Process();
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Normal;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = @"/c -sk server -sky exchange -pe -n CN=localhost -ir LocalMachine -is Root -ic MyCA.cer -sr LocalMachine -ss My MyAdHocTestCert.cer"

use /c as a cmd argument to close cmd.exe once its finish processing your commands

Maybe I write crappy code, but I've come to realize that clicking the trash-can icon on eclipse and netbeans IDEs is a 'good practice'.

My solution is fastest and easiest.

public class MyBase64 {

exit(0) behave like return 0 in main() function, exit(1) behave like return 1. The standard is, that main function return 0, if program ended successfully while non-zero value means that program was terminated with some kind of error.

You can use anycache to do the job for you. It considers all the details:

• It uses dill as backend, which extends the python pickle module to handle lambda and all the nice python features.
• It stores different objects to different files and reloads them properly.
• Limits cache size
• Allows cache clearing
• Allows sharing of objects between multiple runs
• Allows respect of input files which influence the result

Assuming you have a function myfunc which creates the instance:

from anycache import anycache

class Company(object):
    def __init__(self, name, value):
        self.name = name
        self.value = value

@anycache(cachedir='/path/to/your/cache')    
def myfunc(name, value)
    return Company(name, value)

Anycache calls myfunc at the first time and pickles the result to a file in cachedir using an unique identifier (depending on the function name and its arguments) as filename. On any consecutive run, the pickled object is loaded. If the cachedir is preserved between python runs, the pickled object is taken from the previous python run.

For any further details see the documentation

I don't think the camel case is the issue in that example, but I imagine a more RESTful naming convention for the above example would be:

api.service.com/helloWorld/userId/x

rather then making userId a query parameter (which is perfectly legal) my example denotes that resource in, IMO, a more RESTful way.

Okay, I'll write another instruction, because didn't find the clear answer here. So if you faced such problems, follow this:

1. Rename or copy/rename .env.example file in the root of your project to .env.

You should not just create empty .env file, but fill it with content of .env.example.

2. In the terminal go to the project root directory(not public folder) and run

php artisan key:generate

3. If everything is okay, the response in the terminal should look like this

Application key [base64:wbvPP9pBOwifnwu84BeKAVzmwM4TLvcVFowLcPAi6nA=] set successfully.

4. Now just copy key itself and paste it in your .env file as the value to APP_KEY. Result line should look like this:

APP_KEY=base64:wbvPP9pBOwifnwu84BeKAVzmwM4TLvcVFowLcPAi6nA=

5. In terminal run

php artisan config:cache

That's it.

I think all you have to do is change the model to say the date field is nullable and then put [Required] on it if it is required. If you do this the placeholder text does appear.

Next release of ASP.NET MVC (available in January or so) should have MSBuild task that compiles views, so you might want to wait.

See announcement

$('div[imageId="imageN"]').each(function() {
    // `this` is the div
});

To check for the sole existence of the attribute, no matter which value, you could use ths selector instead: $('div[imageId]')

Adding @Manbroski answer here that worked for me:

try Ctrl-Shift-P Editor: Toggle Soft Tabs

Slightly more generic version of what @mark_s posted, this helped me

SELECT 
'ALTER TABLE ' +  OBJECT_SCHEMA_NAME(k.parent_object_id) +
'.[' + OBJECT_NAME(k.parent_object_id) + 
'] DROP CONSTRAINT ' + k.name
FROM sys.foreign_keys k
WHERE referenced_object_id = object_id('your table')

just plug your table name, and execute the result of it.

Several people have recommended adding a null check. Sometimes that's the right thing to do, but not always. Check out this excellent article showing why you'd skip it.

http://misko.hevery.com/2009/02/09/to-assert-or-not-to-assert/

This can work I tried it too.

this.finishAffinity();

This is what ended up working.

$("select").change(function(){
    $.get("/page.html?" + $(this).parent("form").find(":input").serialize()); 
});

For scoping purpose, I use:

custom_object = None

In a nutshell, the more a programming style emphasizes What (to do) abstracting away the details of How (to do it) the more that style is considered to be declarative. The opposite is true for imperative. Functional programming is associated with the declarative style.

Let's un-complicate Bootstrap!

Notice how the col-sm occupies the 100% width (in other terms breaks into new line) below 576px but col doesn't. You can notice the current width at the top center in gif.

Here comes the code:

<div class="container">
    <div class="row">
        <div class="col">col</div>
        <div class="col">col</div>
        <div class="col">col</div>
    </div>
    <div class="row">
        <div class="col-sm">col-sm</div>
        <div class="col-sm">col-sm</div>
        <div class="col-sm">col-sm</div>
    </div>
</div>

Bootstrap by default aligns all the columns(col) in a single row with equal width. In this case three col will occupy 100%/3 width each, whatever the screen size. You can notice that in gif.

Now what if we want to render only one column per line i.e give 100% width to each column but for smaller screens only? Now comes the col-xx classes!

I used col-sm because I wanted to break the columns into separate lines below 576px. These 4 col-xx classes are provided by Bootstrap for different display devices like mobiles, tablets, laptops, large monitors etc.

So,col-sm would break below 576px, col-md would break below 768px, col-lg would break below 992px and col-xl would break below 1200px

Note that there's no col-xs class in bootstrap 4.

This pretty much sums-up. You can go back to work.

But there's bit more to it. Now comes the col-* and col-xx-* for customizing width.

Remember in the above example I mentioned that col or col-xx takes the equal width in a row. So if we want to give more width to a specific col we can do this.

Bootstrap row is divided into 12 parts, so in above example there were 3 col so each one takes 12/3 = 4 part. You can consider these parts as a way to measure width.

We could also write that in format col-* i.e. col-4 like this :

<div class="row">
  <div class="col-4">col</div>
  <div class="col-4">col</div>
  <div class="col-4">col</div>
</div>

And it would've made no difference because by default bootstrap gives equal width to col (4 + 4 + 4 = 12).

But, what if we want to give 7 parts to 1st col, 3 parts to 2nd col and rest 2 parts (12-7-3 = 2) to 3rd col (7+3+2 so total is 12), we can simply do this:

<div class="row">
  <div class="col-7">col-7</div>
  <div class="col-3">col-3</div>
  <div class="col-2">col-2</div>
</div>

and you can customize the width of col-xx-* classes also.

<div class="row">
    <div class="col-sm-7">col-sm-7</div>
    <div class="col-sm-3">col-sm-3</div>
    <div class="col-sm-2">col-sm-2</div>
</div>

How does it look in the action?

What if sum of col is more than 12? Then the col will shift/adjust to below line. Yes, there can be any number of columns for a row!

<div class="row">
        <div class="col-12">col-12</div>
        <div class="col-9">col-9</div>
        <div class="col-6">col-6</div>
        <div class="col-6">col-6</div>
    </div>

What if we want 3 columns in a row for large screens but split these columns into 2 rows for small screens?

<div class="row">
    <div class="col-12 col-sm">col-12 col-sm TOP</div>
    <div class="col col-sm">col col-sm</div>
    <div class="col col-sm">col col-sm</div>
</div>

I used Dave Webb's answer but simplified it a bit. As long as the resource IDs will stay the same during runtime in your use-case, there's not really a need to write your own class implementing Html.ImageGetter and mess around with source-strings.

What I did was using the resource ID as a source-string:

final String img = String.format("<img src=\"%s\"/>", R.drawable.your_image);
final String html = String.format("Image: %s", img);

and use it directly:

Html.fromHtml(html, new Html.ImageGetter() {
  @Override
  public Drawable getDrawable(final String source) {
    Drawable d = null;
    try {
      d = getResources().getDrawable(Integer.parseInt(source));
      d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
    } catch (Resources.NotFoundException e) {
      Log.e("log_tag", "Image not found. Check the ID.", e);
    } catch (NumberFormatException e) {
      Log.e("log_tag", "Source string not a valid resource ID.", e);
    }

    return d;
  }
}, null);

There is a variation on the same theme that uses a for loop, instead of a while loop, to limit the scope of the line variable. Whether it's "better" is a matter of personal taste.

for(String line = reader.readLine(); line != null; line = reader.readLine()) {
    stringBuilder.append(line);
    stringBuilder.append(ls);
}

If you need a function that behaves as a nop, try

nop = lambda *a, **k: None
nop()

Sometimes I do stuff like this when I'm making dependencies optional:

try:
    import foo
    bar=foo.bar
    baz=foo.baz
except:
    bar=nop
    baz=nop

# Doesn't break when foo is missing:
bar()
baz()

Since you are asking for lambdas, you can use the following syntax with Java 8:

Date maxDate = list.stream().map(u -> u.date).max(Date::compareTo).get();

or, if you have a getter for the date:

Date maxDate = list.stream().map(User::getDate).max(Date::compareTo).get();

How about this:

times['days_since'] = max(list(df.index.values))  
times['days_since'] = times['days_since'] - times['months']  
times

Very simple and quick way of finding dupes with one iteration in Python is:

testList = ['red', 'blue', 'red', 'green', 'blue', 'blue']

testListDict = {}

for item in testList:
  try:
    testListDict[item] += 1
  except:
    testListDict[item] = 1

print testListDict

Output will be as follows:

>>> print testListDict
{'blue': 3, 'green': 1, 'red': 2}

function sort() only is only good if your number has same digit, example:

var myData = ["3","11","1","2"]

will return;

var myData = ["1","11","2","3"]

and here improvement for function from mrmonkington

myData.sort().sort(function(a,b){return a - b;}).filter(function(el,i,a){if(i==a.indexOf(el) & el.length>0)return 1;return 0;})

the above function will also delete empty array and you can checkout the demo below

I wanted a function that would join tables without requiring you to define the columns using an anonymous type selector, but had a hard time finding any. I ended up having to make my own. Hopefully this will help anyone in the future who searches for this:

private DataTable JoinDataTables(DataTable t1, DataTable t2, params Func<DataRow, DataRow, bool>[] joinOn)
{
    DataTable result = new DataTable();
    foreach (DataColumn col in t1.Columns)
    {
        if (result.Columns[col.ColumnName] == null)
            result.Columns.Add(col.ColumnName, col.DataType);
    }
    foreach (DataColumn col in t2.Columns)
    {
        if (result.Columns[col.ColumnName] == null)
            result.Columns.Add(col.ColumnName, col.DataType);
    }
    foreach (DataRow row1 in t1.Rows)
    {
        var joinRows = t2.AsEnumerable().Where(row2 =>
            {
                foreach (var parameter in joinOn)
                {
                    if (!parameter(row1, row2)) return false;
                }
                return true;
            });
        foreach (DataRow fromRow in joinRows)
        {
            DataRow insertRow = result.NewRow();
            foreach (DataColumn col1 in t1.Columns)
            {
                insertRow[col1.ColumnName] = row1[col1.ColumnName];
            }
            foreach (DataColumn col2 in t2.Columns)
            {
                insertRow[col2.ColumnName] = fromRow[col2.ColumnName];
            }
            result.Rows.Add(insertRow);
        }
    }
    return result;
}

An example of how you might use this:

var test = JoinDataTables(transactionInfo, transactionItems,
               (row1, row2) =>
               row1.Field<int>("TransactionID") == row2.Field<int>("TransactionID"));

One caveat: This is certainly not optimized, so be mindful when getting to row counts above 20k. If you know that one table will be larger than the other, try to put the smaller one first and the larger one second.

You can redirect stdout into a file "output.txt":

import sys
sys.stdout = open('output.txt','wt')
print ("Hello stackoverflow!")
print ("I have a question.")

Try to list all files' names in the directory by calling:

File file = new File(".");
for(String fileNames : file.list()) System.out.println(fileNames);

and see if you will find your files in the list.

I believe you need to set the cascade option in your mapping via xml/annotation. Refer to Hibernate reference example here.

In case you are using annotation, you need to do something like this,

@OneToMany(cascade = CascadeType.PERSIST) // Other options are CascadeType.ALL, CascadeType.UPDATE etc..

You can find the answer on this other S.O. question:

The following works for me :-)

Here is another reason the console may disappear. And the solution:

With the new Visual Studio 2010 you might see this behavior even when you use Ctrl + F5 aka "start without debugging". This is most likely because you created an "empty project" instead of a "Win32 console application". If you create the project as a "Win32 console application" you can disregard this as it does not apply.

In the older versions it would default to the console subsystem even if you selected "empty project", but not in Visual Studio 2010, so you have to set it manually. To do this select the project in the solution explorer on the right or left (probably is already selected so you don't have to worry about this).

Then select "project" from the menu bar drop down menus, then select "project_name properties" ? "configuration properties" ? "linker" ? "system" and set the first property, the drop down "subsystem" property to "console (/SUBSYSTEM:CONSOLE)". The console window should now stay open after execution as usual.

/////////////////////////////////////////////////////////////////////////////////////

Just give them the same name throughout the form you are using.

<form><input type="radio" name="selection">
      <input type="radio" name="selection">
      ..
      ..
</form>

<a href="@Url.Action("RunReport", "Performance", new { reportView = Model.ReportView.ToString() })" type="submit" id="runReport" target="_blank" class="button Secondary"> @Reports.RunReport </a>

StringBuilder replace method can be used to replace the last character.

StringBuilder.replace(startPosition, endPosition, newString)

StringBuilder builder = new StringBuilder(fieldName);
builder.replace(builder.length()-1, builder.length(), "");
builder.toString();

As HungryDB said the easier way for do that is:

$mystring = json_encode($my_json,JSON_UNESCAPED_SLASHES);

Have a look at your php version because this parameter has been added in version 5.4.0

json_encode documentation

CORRELATED SUBQUERIES: Is evaluated for each row processed by the Main query. Execute the Inner query based on the value fetched by the Outer query. Continues till all the values returned by the main query are matched. The INNER Query is driven by the OUTER Query

Ex:

SELECT empno,fname,sal,deptid FROM emp e WHERE sal=(SELECT AVG(sal) FROM emp WHERE deptid=e.deptid)

The Correlated subquery specifically computes the AVG(sal) for each department.

SUBQUERY: Runs first,executed once,returns values to be used by the MAIN Query. The OUTER Query is driven by the INNER QUERY

The code below solved it for me:

@Override
public void onDestroyView() {
    if (getView() != null) {
        ViewGroup parent = (ViewGroup) getView().getParent();
        parent.removeAllViews();
    }
    super.onDestroyView();
}

Note: The error was from my fragment class and by overriding the onDestroy method like this, I could solve it.

To properly load functions from ~/.config/fish/functions

You may set only ONE function inside file and name file the same as function name + add .fish extension.

This way changing file contents reload functions in opened terminals (note some delay may occur ~1-5s)

That way if you edit either by commandline

function name; function_content; end

then

funcsave name

you have user defined functions in console and custom made in the same order.

I use this :

$(".reset").click(function() {
  $('input[type=text]').each(function(){
     $(this).val('');
  });
});

And here is my button:

<a href="#" class="reset">
  <i class="fa fa-close"></i>
     Reset
</a>

You can use the Standard PHP Library (SPL) to "hide" the recursion.

$a = array(1,2,array(3,4, array(5,6,7), 8), 9);
$it = new RecursiveIteratorIterator(new RecursiveArrayIterator($a));
foreach($it as $v) {
  echo $v, " ";
}

prints

1 2 3 4 5 6 7 8 9 

class Student(object):
    name = ""
    age = 0
    major = ""

    # The class "constructor" - It's actually an initializer 
    def __init__(self, name, age, major):
        self.name = name
        self.age = age
        self.major = major

def make_student(name, age, major):
    student = Student(name, age, major)
    return student

Note that even though one of the principles in Python's philosophy is "there should be one—and preferably only one—obvious way to do it", there are still multiple ways to do this. You can also use the two following snippets of code to take advantage of Python's dynamic capabilities:

class Student(object):
    name = ""
    age = 0
    major = ""

def make_student(name, age, major):
    student = Student()
    student.name = name
    student.age = age
    student.major = major
    # Note: I didn't need to create a variable in the class definition before doing this.
    student.gpa = float(4.0)
    return student

I prefer the former, but there are instances where the latter can be useful – one being when working with document databases like MongoDB.

SELECT cols.table_name, cols.column_name, cols.position, cons.status, cons.owner
FROM all_constraints cons, all_cons_columns cols
WHERE cols.table_name = 'TABLE_NAME'
AND cons.constraint_type = 'P'
AND cons.constraint_name = cols.constraint_name
AND cons.owner = cols.owner
ORDER BY cols.table_name, cols.position;

Make sure that 'TABLE_NAME' is in upper case since Oracle stores table names in upper case.

Selecting text in an element (akin to highlighting with your mouse)

:)

Using the accepted answer on that post, you can call the function like this:

$(function() {
  $('#textareaId').click(function() {
    SelectText('#textareaId');
  });
});

Putting plot.tight_layout() after all changes on the graph, just before show() or savefig() will solve the problem.

You can configure the Javadocs with downloading jar, basically javadocs will be referred directly from internet.

Complete steps:

1. Open the Build Path page of the project (right click, properties, Java build path).
2. Open the Libraries tab.
3. Expand the node of the library in question (JavaFX).
4. Select JavaDoc location and click edit.
5. Enter the location to the file which contains the Javadoc. Specifically for the javaFX javadoc enter http://docs.oracle.com/javafx/2.0/api/

for offline javadocs, you can download from : http://www.oracle.com/technetwork/java/javase/documentation/java-se-7-doc-download-435117.html

After clicking Accept License Agreement you can download javafx-2_2_0-apidocs.zip

nonatomic property means @synthesized methods are not going to be generated threadsafe -- but this is much faster than the atomic property since extra checks are eliminated.

strong is used with ARC and it basically helps you , by not having to worry about the retain count of an object. ARC automatically releases it for you when you are done with it.Using the keyword strong means that you own the object.

weak ownership means that you don't own it and it just keeps track of the object till the object it was assigned to stays , as soon as the second object is released it loses is value. For eg. obj.a=objectB; is used and a has weak property , than its value will only be valid till objectB remains in memory.

copy property is very well explained here

strong,weak,retain,copy,assign are mutually exclusive so you can't use them on one single object... read the "Declared Properties " section

hoping this helps you out a bit...

In MySQL Workbench you need an INDEX to edit, no need it to be PK (although adding a PK is a solution as well).

You can make a regular INDEX or compound INDEX. That's all MySQL WB needs to fix the Read only thing (I have v. 6.2 with MariaDB v. 10.1.4):

Just right click table, select "Alter table..." then go to "Indexes" tab. In the left pane put a custom name for your index, and in the middle pane checkmark one (make sure the vale will be unique) or more fields (just make sure the combination is unique)

There are two ways of doing this.

Most of the answers have correctly pointed out that style.display has no value called "hidden". It should be none.

If you want to use "hidden" the syntax should be as follows.

object.style.visibility="hidden"

The difference between the two is the visibility="hidden" property will only hide the contents of you element but retain it position on the page. Whereas the display ="none" will hide your complete element and the rest of the elements on the page will fill that void created by it.

Check this illustration

DECLARE @Seconds INT = 86200;
SELECT 
CONVERT(VARCHAR(15), 
CAST(CONVERT(VARCHAR(12), @Seconds / 60 / 60 % 24)
+':'+ CONVERT(VARCHAR(2), @Seconds / 60 % 60)
+':'+ CONVERT(VARCHAR(2), @Seconds % 60) AS TIME), 100) AS [HH:MM:SS (AM/PM)]

This should be shorter:

<font color='red'>test blue color font</font>

The view (blade template): Inside the loop you can retrieve whatever column you looking for

 @foreach ($products as $product)
   {{$product->sku}}
 @endforeach

From How do I install a Python package with a .whl file? [sic], How do I install a Python package USING a .whl file ?

For all Windows platforms:

1) Download the .WHL package install file.

2) Make Sure path [C:\Progra~1\Python27\Scripts] is in the system PATH string. This is for using both [pip.exe] and [easy-install.exe].

3) Make sure the latest version of pip.EXE is now installed. At this time of posting:

pip.EXE --version

  pip 9.0.1 from C:\PROGRA~1\Python27\lib\site-packages (python 2.7)

4) Run pip.EXE in an Admin command shell.

 - Open an Admin privileged command shell.

 > easy_install.EXE --upgrade  pip

 - Check the pip.EXE version:
 > pip.EXE --version

 pip 9.0.1 from C:\PROGRA~1\Python27\lib\site-packages (python 2.7)

 > pip.EXE install --use-wheel --no-index 
     --find-links="X:\path to wheel file\DownloadedWheelFile.whl"

Be sure to double-quote paths or path\filenames with embedded spaces in them ! Alternatively, use the MSW 'short' paths and filenames.

From looking at the source code, it seems like the pg_stat_database query gives you the number of connections to the current database for all users. On the other hand, the pg_stat_activity query gives the number of connections to the current database for the querying user only.

Use this:

SELECT *, ROW_NUMBER() OVER (ORDER BY id) AS RowNum FROM
    (SELECT DISTINCT id FROM table WHERE fid = 64) Base

and put the "output" of a query as the "input" of another.

Using CTE:

; WITH Base AS (
    SELECT DISTINCT id FROM table WHERE fid = 64
)

SELECT *, ROW_NUMBER() OVER (ORDER BY id) AS RowNum FROM Base

The two queries should be equivalent.

Technically you could

SELECT DISTINCT id, ROW_NUMBER() OVER (PARTITION BY id ORDER BY id) AS RowNum 
    FROM table
    WHERE fid = 64

but if you increase the number of DISTINCT fields, you have to put all these fields in the PARTITION BY, so for example

SELECT DISTINCT id, description,
    ROW_NUMBER() OVER (PARTITION BY id, description ORDER BY id) AS RowNum 
    FROM table
    WHERE fid = 64

I even hope you comprehend that you are going against standard naming conventions here, id should probably be a primary key, so unique by definition, so a DISTINCT would be useless on it, unless you coupled the query with some JOINs/UNION ALL...

There only two things that MapReduce does NATIVELY: Sort and (implemented by sort) scalable GroupBy.

Most of applications and Design Patterns over MapReduce are built over these two operations, which are provided by shuffle and sort.

You can use LINQ's .Select() to do that. In your case it would go something like:

string Name = yourDbContext
  .MyTable
  .Where(u => u.UserId == 1)
  .Select(u => u.Name)
  .SingleOrDefault(); // This is what actually executes the request and return a response

If you are expecting more than one entry in response, you can use .ToList() instead, to execute the request. Something like this, to get the Name of everyone with age 30:

string[] Names = yourDbContext
  .MyTable
  .Where(u => u.Age == 30)
  .Select(u => u.Name)
  .ToList();

Use the constructor that takes a File and a boolean

FileOutputStream(File file, boolean append) 

and set the boolean to true. That way, the data you write will be appended to the end of the file, rather than overwriting what was already there.

I think a more reliable way of closing a connection is to tell the sever explicitly to close it in a way compliant with HTTP specification:

HTTP/1.1 defines the "close" connection option for the sender to signal that the connection will be closed after completion of the response. For example,

   Connection: close

in either the request or the response header fields indicates that the connection SHOULD NOT be considered `persistent' (section 8.1) after the current request/response is complete.

The Connection: close header is added to the actual request:

r = requests.post(url=url, data=body, headers={'Connection':'close'})

Follow these 2 steps:

STEP 1 :

Follow these steps using the Services Tab:

1. Right click on Database
2. Create new Connection

Customize the New COnnection as follows:

1. Connector Name: MYSQL (Connector/J Driver)
2. Host: localhost
3. Port: 3306
4. Database: mysql ( mysql is the default or enter your database name)
5. Username: enter your database username
6. Password: enter your database password
7. JDBC URL: jdbc:mysql://localhost:3306/mysql
8. CLick Finish button

NB: DELETE the ?zeroDateTimeBehaviour=convertToNull part in the URL. Instead of mysql in the URL, you should see your database name)

STEP 2 :

1. Right click on MySQL Server at localhost:3306:[username](...)
2. Select Properties... from the shortcut menu

In the "MySQL Server Properties" dialog select the "Admin Properties" tab Enter the following in the textboxes specified:

For Linux users :

1. Path to start command: /usr/bin/mysql
2. Arguments: /etc/init.d/mysql start
3. Path to Stop command: /usr/bin/mysql
4. Arguments: /etc/init.d/mysql stop

For MS Windows users :

NOTE: Optional:

In the Path/URL to admin tool field, type or browse to the location of your MySQL Administration application such as the MySQL Admin Tool, PhpMyAdmin, or other web-based administration tools.

Note: mysqladmin is the MySQL admin tool found in the bin folder of the MySQL installation directory. It is a command-line tool and not ideal for use with the IDE.

Place this css in your page:

<style>
   #client_logos {
    display: inline-block;
    width:100%;
    }
  </style>

Replace

<p><img class="alignnone" style="display: inline; margin: 0 10px;" title="heartica_logo" src="https://s3.amazonaws.com/rainleader/assets/heartica_logo.png" alt="" width="150" height="50" /><img class="alignnone" style="display: inline; margin: 0 10px;" title="mouseflow_logo" src="https://s3.amazonaws.com/rainleader/assets/mouseflow_logo.png" alt="" width="150" height="50" /><img class="alignnone" style="display: inline; margin: 0 10px;" title="mouseflow_logo" src="https://s3.amazonaws.com/rainleader/assets/piiholo_logo.png" alt="" width="150" height="50" /></p>

To

<div id="client_logos">
<img style="display: inline; margin: 0 5px;" title="heartica_logo" src="https://s3.amazonaws.com/rainleader/assets/heartica_logo.png" alt="" width="150" height="50" />
<img style="display: inline; margin: 0 5px;" title="mouseflow_logo" src="https://s3.amazonaws.com/rainleader/assets/mouseflow_logo.png" alt="" width="150" height="50" />
<img style="display: inline; margin: 0 5px;" title="piiholo_logo" src="https://s3.amazonaws.com/rainleader/assets/piiholo_logo.png" alt="" width="150" height="50" />
</div>

I use this function:

# Returns True if End-Of-File is reached
def EOF(f):
    current_pos = f.tell()
    file_size = os.fstat(f.fileno()).st_size
    return current_pos >= file_size

char * strdup(const char * s)
{
  size_t len = 1+strlen(s);
  char *p = malloc(len);

  return p ? memcpy(p, s, len) : NULL;
}

Maybe the code is a bit faster than with strcpy() as the \0 char doesn't need to be searched again (It already was with strlen()).

I had this same problem, common also to other borwsers like Firefox. Finally I discovered that dynamically create an element with animated gif inside at form submit did not animate, so I developed the following workaorund.

1) At document.ready(), each FORM found in page, receive position:relative property and then to each one is attached an invisible DIV.bg-overlay.

2) After this, assuming that each submit value of my website is identified by btn-primary css class, again at document.ready(), I look for these buttons, traverse to the FORM parent of each one, and at form submit, I fire showOverlayOnFormExecution(this,true); function, passing clicked button and a boolean that toggle visibility of DIV.bg-overlay.

$(document).ready(function() {

  //Append LOADING image to all forms
  $('form').css('position','relative').append('<div class="bg-overlay" style="display:none;"><img src="/images/loading.gif"></div>');

  //At form submit, fires a specific function
  $('form .btn-primary').closest('form').submit(function (e) {
    showOverlayOnFormExecution(this,true);
  });
});

CSS for DIV.bg-overlay is the following:

.bg-overlay
{
  width:100%;
  height:100%;
  position:absolute;
  top:0;
  left:0;
  background:rgba(255,255,255,0.6);
  z-index:100;
}

.bg-overlay img
{
  position:absolute;
  left:50%;
  top:50%;
  margin-left:-40px; //my loading images is 80x80 px. This is done to center it horizontally and vertically.
  margin-top:-40px;
  max-width:auto;
  max-height:80px;
}

3) At any form submit, the following function is fired to show a semi-white background overlay all over it (that deny ability to interact again with form) and an animated gif inside it (that visually show a loading action).

function showOverlayOnFormExecution(clicked_button, showOrNot) 
{
    if(showOrNot == 1)
    {
        //Add "content" of #bg-overlay_container (copying it) to the confrm that contains clicked button 
        $(clicked_button).closest('form').find('.bg-overlay').show();
    }
    else
        $('form .bg-overlay').hide();
}

Showing animated gif at form submit, instead of appending it at this event, solves "gif animation freeze" problem of various browsers (as said, I found this problem in IE and Firefox, not in Chrome)

Set decoding to true

Your decoding is not set to true. If you don't have access to set the source to true. The code below will fix it for you.

$WorkingArray = json_decode(json_encode($data),true);

I ran into same issue below piece of code worked for me

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

request.Headers["UserAgent"] = "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; 
Trident/5.0)"

If you are using jQuery 1.2 or newer, you can simply use these:

$(window).width();
$(document).width();
$(window).height();
$(document).height();

From there it is a simple matter to decide the height of your element.

It looks like what you really want a ListView with a custom adapter to inflate the specified layout. Using an ArrayAdapter and the method notifyDataSetChanged() you have full control of the Views generation and rendering.

Take a look at these tutorials

• http://www.softwarepassion.com/android-series-custom-listview-items-and-adapters/
• http://developerlife.com/tutorials/?p=327
• http://www.androidguys.com/2008/07/14/fancy-listviews-part-one/

The error SyntaxError: invalid character in identifier means you have some character in the middle of a variable name, function, etc. that's not a letter, number, or underscore. The actual error message will look something like this:

  File "invalchar.py", line 23
    values =  list(analysis.values ())
                ^
SyntaxError: invalid character in identifier

That tells you what the actual problem is, so you don't have to guess "where do I have an invalid character"? Well, if you look at that line, you've got a bunch of non-printing garbage characters in there. Take them out, and you'll get past this.

If you want to know what the actual garbage characters are, I copied the offending line from your code and pasted it into a string in a Python interpreter:

>>> s='    values ??=  list(analysis.values ??())'
>>> s
'    values \u200b\u200b=  list(analysis.values \u200b\u200b())'

So, that's \u200b, or ZERO WIDTH SPACE. That explains why you can't see it on the page. Most commonly, you get these because you've copied some formatted (not plain-text) code off a site like StackOverflow or a wiki, or out of a PDF file.

If your editor doesn't give you a way to find and fix those characters, just delete and retype the line.

Of course you've also got at least two IndentationErrors from not indenting things, at least one more SyntaxError from stay spaces (like = = instead of ==) or underscores turned into spaces (like analysis results instead of analysis_results).

The question is, how did you get your code into this state? If you're using something like Microsoft Word as a code editor, that's your problem. Use a text editor. If not… well, whatever the root problem is that caused you to end up with these garbage characters, broken indentation, and extra spaces, fix that, before you try to fix your code.

I vote for IB(Interactive Brokers). I've used them in the past as was quite happy. Pinnacle Capital Markets trading also has an API (pcmtrading.com) but I haven't used them.

JE and JZ are just different names for exactly the same thing: a conditional jump when ZF (the "zero" flag) is equal to 1.

(Similarly, JNE and JNZ are just different names for a conditional jump when ZF is equal to 0.)

You could use them interchangeably, but you should use them depending on what you are doing:

• JZ/JNZ are more appropriate when you are explicitly testing for something being equal to zero:

  dec  ecx
  jz   counter_is_now_zero
  

• JE and JNE are more appropriate after a CMP instruction:

  cmp  edx, 42
  je   the_answer_is_42
  

  (A CMP instruction performs a subtraction, and throws the value of the result away, while keeping the flags; which is why you get ZF=1 when the operands are equal and ZF=0 when they're not.)

You can use bind method to attach function to several events. Just pass the event names and the handler function as in this code:

$('#foo').bind('mouseenter mouseleave', function() {
  $(this).toggleClass('entered');
});

Another option is to use chaining support of jquery api.

Ran into the diagram while looking at key-value coding, thought it might help someone. It helps with understanding of what IBOutlet is.

By looking at the flow, one could see that IBOutlets are only there to match the property name with a control name in the Nib file.

For me it was changing.

this.name = response.data;

To what computed returns so;

this.$store.state.name = response.data;

I do not know why, but the image should not be duplicated, tripled, etc ... should remove the previous one and load it again but with another rotation data. This is my code:

data.csv enter image description here

d3.csv("data/data.csv").then(function(data){
//console.log(data);
// Clean data
formattedData = data.map(function(id){
id.rot_1 = +id.rot_1;
        id.trans_1 = +id.trans_1;
        return id;
});
// First run of the visualization
update(formattedData[0]);})

$("#play-button")
.on("click", function(){
    var button = $(this);
    if (button.text() == "Play"){
        button.text("Pause");
        interval = setInterval(step, 1000);            
    }
    else {
        button.text("Play");
        clearInterval(interval);
    }})

function step(){
// At the end of our data, loop back
time = (time < 76) ? time+1 : 0
update(formattedData[time]); }

function update(data) {
// Standard transition time for the visualization
var t = d3.transition()
    .duration(1000);

//console.log(d3.selectAll(data));    
//console.log(data)

// original
var imgs1 = g.append("image") // en vez de g es svg
.attr("xlink:href", "img/picturetest.png");

// EXIT old elements not present in new data.
imgs1.exit()
    .attr("class", "exit")
    .selectAll("svg:image")
    .remove();

//console.log(data)

// ENTER new elements present in new data.
imgs1.enter()
    .append("svg:image") // svg:image
    //.attr("xlink:href", "img/picturetest.png")
    .attr("class", "enter")
    .merge(imgs1)
    .transition(t)
        .attr("x", 0) // 150
        .attr("y", 0) // 80
        .attr("width", 200)
        .attr("height", 200)
        .attr("transform", "rotate("+data.rot_1+") translate("+data.trans_1+")" ); }`

So you want to split on spaces, and on commas and periods that aren't surrounded by numbers. This should work:

r" |(?<![0-9])[.,](?![0-9])"

Your response object is declared as a ServletResponse. To use the sendRedirect() method, you have to cast it to HttpServletResponse. This is an extended interface that adds methods related to the HTTP protocol.

Sometimes it is necessary to load scripts in a specific order. For example jQuery must be loaded before jQuery UI. Most examples on this page load scripts in parallel (asynchronously) which means order of execution is not guaranteed. Without ordering, script y that depends on x could break if both are successfully loaded but in wrong order.

I propose a hybrid approach which allows sequential loading of dependent scripts + optional parallel loading + deferred objects:

 * loads scripts one-by-one using recursion_x000D_
 * returns jQuery.Deferred_x000D_

The scripts in both queues will download in parallel, however, the scripts in each queue will download in sequence, ensuring ordered execution. Waterfall chart:

Then tell read.table not to use row.names:

systems <- read.table("http://getfile.pl?test.csv", 
                      header=TRUE, sep=",", row.names=NULL)

and now your rows will simply be numbered.

Also look at read.csv which is a wrapper for read.table which already sets the sep=',' and header=TRUE arguments so that your call simplifies to

systems <- read.csv("http://getfile.pl?test.csv", row.names=NULL)

Jan 2018 UPDATE: When I answered this question last year, I neglected to mention a third way to access Google APIs with JavaScript, and that would be from Node.js apps using its client library, so I added it below.

It's Mar 2017, and most of the answers here are outdated -- the accepted answer now refers to a library that uses an older API version. A more current answer: you can access most Google APIs with JavaScript only. Google provides 3 ways to do this today:

1. As mentioned in the answer by Dan Dascalescu, you can use Google Apps Script, the JavaScript-in-Google's-cloud solution. That is, non-Node server-side JS apps outside the browser that run on Google servers.
   • You code your apps in the Apps Script code editor, and they can access Google Sheets in two different ways:
     1. The Spreadsheet Service (native object support; usage guide); native is easier but is generally older than...
     2. The Google Sheets Advanced Service (directly access the latest Google Sheets REST API [see below]; usage guide)
   • Apps Script also powers add-ons, and you can extend Sheets UI functionality with Sheets add-ons (like these)
   • You can even write mobile add-ons which extend the Sheets app on Android
   • To learn more about using Apps Script, check out these videos I've created (most involve the use of Sheets)
2. You can also use the Google APIs Client Library for JavaScript to access the latest Google Sheets REST API on the client side.
   • Here are some generic samples of using the client library
   • The latest Sheets API (v4) was released at Google I/O 2016; it's much more powerful than all previous versions, giving developers programmatic access to most features found in the Sheets UI
   • Here is the JavaScript quickstart for the API to help you get started
   • Here are sample "recipes" (JSON payloads) for core API requests
   • If you're not "allergic" to Python (if you are, just pretend it's pseudocode ;) ), I made several videos with more "real-world" samples of using the API you can learn from and migrate to JS if desired (NOTE: even though it's Python code, most API requests have JSON & easily portable to JS):
     1. Migrating SQL data to a Sheet (code deep dive post)
     2. Formatting text using the Sheets API (code deep dive post)
     3. Generating slides from spreadsheet data (code deep dive post)
     4. Those and others in the Sheets API video library
3. The 3rd way to access Google APIs with JavaScript is from Node.js apps using its client library. It works similarly to using the JavaScript (client) client library described just above, only you'll be accessing the same API from the server-side. Here's the Node.js Quickstart example for Sheets. You may find the Python-based videos above to be even more useful as they too access the API from the server-side.

When using the REST API, you need to manage & store your source code as well as perform authorization by rolling your own auth code (see samples above). Apps Script handles this on your behalf, managing the data (reducing the "pain" as mentioned by Ape-inago in their answer), and your code is stored on Google's servers. But your functionality is restricted to what services App Script provides whereas the REST API gives developers much broader access to the API. But hey, it's good to have choices, right? In summary, to answer the OP original question, instead of zero, developers have three ways of accessing Google Sheets using JavaScript.

Surprisingly, none of answers talk about how it is achieved by hibernate behind the screens.

Lazy loading is a design pattern that is effectively used in hibernate for performance reasons which involves following techniques.

1. Byte code instrumentation:

Enhances the base class definition with hibernate hooks to intercept all the calls to that entity object.

Done either at compile time or run[load] time

1.1 Compile time

• Post compile time operation

• Mostly by maven/ant plugins

1.2 Run time

• If no compile time instrumentation is done, this is created at run time Using libraries like javassist

2. Proxies

The entity object that Hibernate returns are proxy of the real type.

See also: Javassist. What is the main idea and where real use?

If you add ?__a=1 at the end of Instagram public URLs, you get the data of the public URL in JSON.

For the media ID of an image from post URL, simply add the JSON request code at the post URL:

http://instagram.com/p/Y7GF-5vftL/?__a=1

The response will look like this below. You can easily recover the image ID from the "id" parameter in the reply...

You can use:

element = driver.find_element_by_class_name("class_name").text

This will return the text within the element and will allow you to verify it after that.

You are trying to assign to literal integer values. 1, 2, etc. are not valid names; they are only valid integers:

>>> 1
1
>>> 1 = 'something'
  File "<stdin>", line 1
SyntaxError: can't assign to literal

You probably want to use a list or dictionary instead:

names = []
for i in range(1, 6):
    name = input("Please enter name {}:".format(i))
    names.append(name)

Using a list makes it much easier to pick a random value too:

winner = random.choice(names)
print('Well done {}. You are the winner!'.format(winner))

Copy the project files from the original source and paste it somewhere and then import from the Android Studio.

This is very simple, you just need to add a background image to the select element and position it where you need to, but don't forget to add:

-webkit-appearance: none;
-moz-appearance: none;
appearance: none;

According to http://shouldiprefix.com/#appearance

Microsoft Edge and IE mobile support this property with the -webkit- prefix rather than -ms- for interop reasons.

I just made this fiddle http://jsfiddle.net/drjorgepolanco/uxxvayqe/

A bash function that uses perl to generate a random number of n digits. Specify either the number of digits or a template of n 0s.

rand() {
  perl -E '$ARGV[0]||=""; $ARGV[0]=int($ARGV[0])||length($ARGV[0]); say join "", int(rand(9)+1)*($ARGV[0]?1:0), map { int(rand(10)) } (0..($ARGV[0]||0)-2)' $1
}

Usage:

$ rand 3
381
$ rand 000
728

Array with range of numbers at random order:

$numbers = range(1, 20);
shuffle($numbers);

Wrapped function:

function UniqueRandomNumbersWithinRange($min, $max, $quantity) {
    $numbers = range($min, $max);
    shuffle($numbers);
    return array_slice($numbers, 0, $quantity);
}

Example:

<?php
print_r( UniqueRandomNumbersWithinRange(0,25,5) );
?>

Result:

 Array
(
    [0] => 14
    [1] => 16
    [2] => 17
    [3] => 20
    [4] => 1
)

After the merge, it's safe to delete the branch:

git branch -d branch1

Additionally, git will warn you (and refuse to delete the branch) if it thinks you didn't fully merge it yet. If you forcefully delete a branch (with git branch -D) which is not completely merged yet, you have to do some tricks to get the unmerged commits back though (see below).

There are some reasons to keep a branch around though. For example, if it's a feature branch, you may want to be able to do bugfixes on that feature still inside that branch.

If you also want to delete the branch on a remote host, you can do:

git push origin :branch1

This will forcefully delete the branch on the remote (this will not affect already checked-out repositiories though and won't prevent anyone with push access to re-push/create it).

git reflog shows the recently checked out revisions. Any branch you've had checked out in the recent repository history will also show up there. Aside from that, git fsck will be the tool of choice at any case of commit-loss in git.

Just in case you want to do this dynamically;

function enableScrollwheel(map) {
    if(map) map.setOptions({ scrollwheel: true });
}

function disableScrollwheel(map) {
    if(map) map.setOptions({ scrollwheel: false });
}

Sometimes you have to show something "complex" over the map (or the map is a small part of the layout), and this scroll zooming gets in the middle, but once you have a clean map, this way of zooming is nice.

To get a list of threads and their full states using the terminal, you can use the command below:

jstack -l <PID>

Which <PID> is the id of process running on your computer. To get the process id of your java process you can simply run the jps command.

Also, you can analyze your thread dump that produced by jstack in TDAs (Thread Dump Analyzer) such fastthread or spotify thread analyzer tool.

Here's a chunk of code that will write values to a log file. If the file doesn't exist, it creates it, otherwise it just appends to the existing file. You need to add "using System.IO;" at the top of your code, if it's not already there.

string strLogText = "Some details you want to log.";

// Create a writer and open the file:
StreamWriter log;

if (!File.Exists("logfile.txt"))
{
  log = new StreamWriter("logfile.txt");
}
else
{
  log = File.AppendText("logfile.txt");
}

// Write to the file:
log.WriteLine(DateTime.Now);
log.WriteLine(strLogText);
log.WriteLine();

// Close the stream:
log.Close();

I think the others have answered your second question. As for the first, the "Hello World" of CUDA, I don't think there is a set standard, but personally, I'd recommend a parallel adder (i.e. a programme that sums N integers).

If you look the "reduction" example in the NVIDIA SDK, the superficially simple task can be extended to demonstrate numerous CUDA considerations such as coalesced reads, memory bank conflicts and loop unrolling.

See this presentation for more info:

http://www.gpgpu.org/sc2007/SC07_CUDA_5_Optimization_Harris.pdf

You should use the HasValue property:

SomeProperty.HasValue

For example:

if (SomeProperty.HasValue)
{
    // Do Something
}
else
{
    // Do Something Else
}

FYI

public Nullable<System.Guid> SomeProperty { get; set; }

is equivalent to:

public System.Guid? SomeProperty { get; set; }

I believe you are looking for the setTimeout function.

To make your code a little neater, define a separate function for onclick in a <script> block:

function myClick() {
  setTimeout(
    function() {
      document.getElementById('div1').style.display='none';
      document.getElementById('div2').style.display='none';
    }, 5000);
}

then call your function from onclick

onclick="myClick();"

floor((day(@DateValue)-1)/7)+1

If you use jquery.ui, try this code:

$.position.scrollbarWidth()

You can use disabled attribute to disable the textbox.

document.getElementById('color').disabled = true;

SELECT StaffId,(Title+''+FirstName+''+LastName) AS FullName 
FROM StaffInformation

Where do you write with in the brackets this will be appear in the one single column. Where do you want a dot into the middle of the Title and First Name write syntax below,

SELECT StaffId,(Title+'.'+FirstName+''+LastName) AS FullName 
FROM StaffInformation

These syntax works with MS SQL Server 2008 R2 Express Edition.

it looks like you are adding a blank item, and then databinding, which would empty the list; try inserting the blank item after databinding

Just found this, and its even shorter.

import time
def expires():
    '''return a UNIX style timestamp representing 5 minutes from now'''
    return int(time.time()+300)

As of Laravel 5 the database username and password goes in the .env file that exists in the project directory, e.g.

DB_HOST=127.0.0.1
DB_DATABASE=db1
DB_USERNAME=user1
DB_PASSWORD=pass1

As you can see these environment variables are overriding the 'forge' strings here so changing them has no effect:

    'mysql' => [
        'driver'    => 'mysql',
        'host'      => env('DB_HOST', 'localhost'),
        'database'  => env('DB_DATABASE', 'forge'),
        'username'  => env('DB_USERNAME', 'forge'),
        'password'  => env('DB_PASSWORD', ''),
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
        'strict'    => false,
    ],

The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date') declare the date property like so: private _date: string;. Also, make sure you are instantiating the model with the new keyword. Lastly, access the property using regular dot notation.

Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :

let passcode = "secret passcode";

class Employee {
    private _fullName: string;

    get fullName(): string {
        return this._fullName;
    }

    set fullName(newName: string) {
        if (passcode && passcode == "secret passcode") {
            this._fullName = newName;
        }
        else {
            console.log("Error: Unauthorized update of employee!");
        }
    }
}

let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
    console.log(employee.fullName);
}
