You can't simulate a click event with javascript. jQuery .trigger() function only fires an event named "click" on the element, which you can capture with .on() jQuery method.

$('body').click(function(){ alert('test' )})

var foo = $.data( $('body').get(0), 'events' ).click
// you can query $.data( object, 'events' ) and get an object back, then see what events are attached to it.

$.each( foo, function(i,o) {
    alert(i) // guid of the event
    alert(o) // the function definition of the event handler
});

You can inspect by feeding the object reference ( not the jQuery object though ) to $.data, and for the second argument feed 'events' and that will return an object populated with all the events such as 'click'. You can loop through that object and see what the event handler does.

another way to do it:

<Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}" SnapsToDevicePixels="true">
                    <StackPanel>
                        <Image Source="{Binding ProductImage,RelativeSource={RelativeSource TemplatedParent}}" Stretch="Fill" Width="65" Height="85"/>
                        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                        <Button x:Name="myButton" Width="40" Height="10">
                            <Popup Width="100" Height="70" IsOpen="{Binding ElementName=myButton,Path=IsMouseOver, Mode=OneWay}">
                                <StackPanel Background="Yellow">
                                    <ItemsControl ItemsSource="{Binding Produkt.SubProducts}"/>
                                </StackPanel>
                            </Popup>
                        </Button>
                    </StackPanel>
                </Border>

Stopping the Storyboard can be done in the code behind, or the xaml, depending on where the need comes from.

If the EventTrigger is moved outside of the button, then we can go ahead and target it with another EventTrigger that will tell the storyboard to stop. When the storyboard is stopped in this manner it will not revert to the previous value.

Here I've moved the Button.Click EventTrigger to a surrounding StackPanel and added a new EventTrigger on the the CheckBox.Click to stop the Button's storyboard when the CheckBox is clicked. This lets us check and uncheck the CheckBox when it is clicked on and gives us the desired unchecking behavior from the button as well.

    <StackPanel x:Name="myStackPanel">

        <CheckBox x:Name="myCheckBox"
                  Content="My CheckBox" />

        <Button Content="Click to Uncheck"
                x:Name="myUncheckButton" />

        <Button Content="Click to check the box in code."
                Click="OnClick" />

        <StackPanel.Triggers>

            <EventTrigger RoutedEvent="Button.Click"
                          SourceName="myUncheckButton">
                <EventTrigger.Actions>
                    <BeginStoryboard x:Name="myBeginStoryboard">
                        <Storyboard x:Name="myStoryboard">
                            <BooleanAnimationUsingKeyFrames Storyboard.TargetName="myCheckBox"
                                                            Storyboard.TargetProperty="IsChecked">
                                <DiscreteBooleanKeyFrame KeyTime="00:00:00"
                                                         Value="False" />
                            </BooleanAnimationUsingKeyFrames>
                        </Storyboard>
                    </BeginStoryboard>
                </EventTrigger.Actions>
            </EventTrigger>

            <EventTrigger RoutedEvent="CheckBox.Click"
                          SourceName="myCheckBox">
                <EventTrigger.Actions>
                    <StopStoryboard BeginStoryboardName="myBeginStoryboard" />
                </EventTrigger.Actions>
            </EventTrigger>

        </StackPanel.Triggers>
    </StackPanel>

To stop the storyboard in the code behind, we will have to do something slightly different. The third button provides the method where we will stop the storyboard and set the IsChecked property back to true through code.

We can't call myStoryboard.Stop() because we did not begin the Storyboard through the code setting the isControllable parameter. Instead, we can remove the Storyboard. To do this we need the FrameworkElement that the storyboard exists on, in this case our StackPanel. Once the storyboard is removed, we can once again set the IsChecked property with it persisting to the UI.

    private void OnClick(object sender, RoutedEventArgs e)
    {
        myStoryboard.Remove(myStackPanel);
        myCheckBox.IsChecked = true;
    }

As for how to represent a single apostrophe as a string in Python, you can simply surround it with double quotes ("'") or you can escape it inside single quotes ('\'').

To remove apostrophes from a string, a simple approach is to just replace the apostrophe character with an empty string:

>>> "didn't".replace("'", "")
'didnt'

In Guava you don't have to wait for a Collection to be returned to you but can actually iterate over the files. It is easy to imagine a IDoSomethingWithThisFile interface in the signature of the below function:

public static void collectFilesInDir(File dir) {
    TreeTraverser<File> traverser = Files.fileTreeTraverser();
    FluentIterable<File> filesInPostOrder = traverser.preOrderTraversal(dir);
    for (File f: filesInPostOrder)
        System.out.printf("File: %s\n", f.getPath());
}

TreeTraverser also allows you to between various traversal styles.

I dont know whether this is duplicate answer or not. If it is I am sorry. I just want to let the needy know how I solved my issue using ToList().

In my case I got same exception for below query.

int id = adjustmentContext.InformationRequestOrderLinks.Where(
             item => item.OrderNumber == irOrderLinkVO.OrderNumber 
                  && item.InformationRequestId == irOrderLinkVO.InformationRequestId)
             .Max(item => item.Id);

I solved like below

List<Entities.InformationRequestOrderLink> links = 
      adjustmentContext.InformationRequestOrderLinks
           .Where(item => item.OrderNumber == irOrderLinkVO.OrderNumber 
                       && item.InformationRequestId == irOrderLinkVO.InformationRequestId)
           .ToList();

int id = 0;

if (links.Any())
{
  id = links.Max(x => x.Id);
}
if (id == 0)
{
//do something here
}

The answer by @Darius is the most idiomatic (and probably more performant) method. One limitation is that the type you are checking has to be of type interface{}. If you use a concrete type it will fail.

An alternative way to determine the type of something at run-time, including concrete types, is to use the Go reflect package. Chaining TypeOf(x).Kind() together you can get a reflect.Kind value which is a uint type: http://golang.org/pkg/reflect/#Kind

You can then do checks for types outside of a switch block, like so:

import (
    "fmt"
    "reflect"
)

// ....

x := 42
y := float32(43.3)
z := "hello"

xt := reflect.TypeOf(x).Kind()
yt := reflect.TypeOf(y).Kind()
zt := reflect.TypeOf(z).Kind()

fmt.Printf("%T: %s\n", xt, xt)
fmt.Printf("%T: %s\n", yt, yt)
fmt.Printf("%T: %s\n", zt, zt)

if xt == reflect.Int {
    println(">> x is int")
}
if yt == reflect.Float32 {
    println(">> y is float32")
}
if zt == reflect.String {
    println(">> z is string")
}

Which prints outs:

reflect.Kind: int
reflect.Kind: float32
reflect.Kind: string
>> x is int
>> y is float32
>> z is string

Again, this is probably not the preferred way to do it, but it's good to know alternative options.

If you google for sort order windows explorer you will find out that Windows Explorer (since Windows XP) obviously uses the function StrCmpLogicalW in the sort order "by name". I did not find information about the treatment of the underscore character. I was amused by the following note in the documentation:

Behavior of this function, and therefore the results it returns, can change from release to release. ...

You can use a transparent poster image in combination with a CSS background image to achieve this (example); however, to have a background stretched to the height and the width of a video, you'll have to use an absolutely positioned <img> tag (example).

It is also possible to set background-size to 100% 100% in browsers that support background-size (example).

Update

A better way to do this would be to use the object-fit CSS property as @Lars Ericsson suggests.

Use

object-fit: cover;

if you don't want to display those parts of the image that don't fit the video's aspect ratio, and

object-fit: fill;

to stretch the image to fit your video's aspect ratio

Example

getPathInfo() gives the extra path information after the URI, used to access your Servlet, where as getRequestURI() gives the complete URI.

I would have thought they would be different, given a Servlet must be configured with its own URI pattern in the first place; I don't think I've ever served a Servlet from root (/).

For example if Servlet 'Foo' is mapped to URI '/foo' then I would have thought the URI:

/foo/path/to/resource

Would result in:

RequestURI = /foo/path/to/resource

and

PathInfo = /path/to/resource

The Servlet 2.4 specification says this about WEB-INF (page 70):

A special directory exists within the application hierarchy named WEB-INF. This directory contains all things related to the application that aren’t in the document root of the application. The WEB-INF node is not part of the public document tree of the application. No file contained in the WEB-INF directory may be served directly to a client by the container. However, the contents of the WEB-INF directory are visible to servlet code using the getResource and getResourceAsStream method calls on the ServletContext, and may be exposed using the RequestDispatcher calls.

This means that WEB-INF resources are accessible to the resource loader of your Web-Application and not directly visible for the public.

This is why a lot of projects put their resources like JSP files, JARs/libraries and their own class files or property files or any other sensitive information in the WEB-INF folder. Otherwise they would be accessible by using a simple static URL (usefull to load CSS or Javascript for instance).

Your JSP files can be anywhere though from a technical perspective. For instance in Spring you can configure them to be in WEB-INF explicitly:

<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"
    p:prefix="/WEB-INF/jsp/" 
    p:suffix=".jsp" >
</bean>

The WEB-INF/classes and WEB-INF/lib folders mentioned in Wikipedia's WAR files article are examples of folders required by the Servlet specification at runtime.

It is important to make the difference between the structure of a project and the structure of the resulting WAR file.

The structure of the project will in some cases partially reflect the structure of the WAR file (for static resources such as JSP files or HTML and JavaScript files, but this is not always the case.

The transition from the project structure into the resulting WAR file is done by a build process.

While you are usually free to design your own build process, nowadays most people will use a standardized approach such as Apache Maven. Among other things Maven defines defaults for which resources in the project structure map to what resources in the resulting artifact (the resulting artifact is the WAR file in this case). In some cases the mapping consists of a plain copy process in other cases the mapping process includes a transformation, such as filtering or compiling and others.

One example: The WEB-INF/classes folder will later contain all compiled java classes and resources (src/main/java and src/main/resources) that need to be loaded by the Classloader to start the application.

Another example: The WEB-INF/lib folder will later contain all jar files needed by the application. In a maven project the dependencies are managed for you and maven automatically copies the needed jar files to the WEB-INF/lib folder for you. That explains why you don't have a lib folder in a maven project.

Although git pull origin yourbranch works, it's not really a good idea

You can alternatively do the following:

git fetch origin
git merge origin/yourbranch

The first line fetches all the branches from origin, but doesn't merge with your branches. This simply completes your copy of the repository.

The second line merges your current branch with that of yourbranch that you fetched from origin (which is one of your remotes).

This is assuming origin points to the repository at address ssh://11.21.3.12:23211/dir1/dir2

jQuery has some issues loading binary data using AJAX requests, as it does not yet implement some HTML5 XHR v2 capabilities, see this enhancement request and this discussion

Given that, you have one of two solutions:

First solution, abandon JQuery and use XMLHTTPRequest

Go with the native HTMLHTTPRequest, here is the code to do what you need

  var req = new XMLHttpRequest();
  req.open("GET", "/file.pdf", true);
  req.responseType = "blob";

  req.onload = function (event) {
    var blob = req.response;
    console.log(blob.size);
    var link=document.createElement('a');
    link.href=window.URL.createObjectURL(blob);
    link.download="Dossier_" + new Date() + ".pdf";
    link.click();
  };

  req.send();

Second solution, use the jquery-ajax-native plugin

The plugin can be found here and can be used to the XHR V2 capabilities missing in JQuery, here is a sample code how to use it

$.ajax({
  dataType: 'native',
  url: "/file.pdf",
  xhrFields: {
    responseType: 'blob'
  },
  success: function(blob){
    console.log(blob.size);
      var link=document.createElement('a');
      link.href=window.URL.createObjectURL(blob);
      link.download="Dossier_" + new Date() + ".pdf";
      link.click();
  }
});

With keys as tuples, you just filter the keys with given second component and sort it:

blue_fruit = sorted([k for k in data.keys() if k[1] == 'blue'])
for k in blue_fruit:
  print k[0], data[k] # prints 'banana 24', etc

Sorting works because tuples have natural ordering if their components have natural ordering.

With keys as rather full-fledged objects, you just filter by k.color == 'blue'.

You can't really use dicts as keys, but you can create a simplest class like class Foo(object): pass and add any attributes to it on the fly:

k = Foo()
k.color = 'blue'

These instances can serve as dict keys, but beware their mutability!

I'm surprised no one mentioned mapping the file into memory: mmap

With this you can access the file as if it were already loaded into memory and the OS will take care of mapping it in and out as possible. Also, if you do this from 2 independent processes and they map the file "shared", they will share the underlying memory.

Once mapped, it will behave like a bytearray. You can use regular expressions, find or any of the other common methods.

Beware that this approach is a little OS specific. It will not be automatically portable.

To fix the issue you can type below command:

'npm -g update'

This is a two-step process:

1. you need to create a login to SQL Server for that user, based on its Windows account

   CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
   

2. you need to grant this login permission to access a database:

   USE (your database)
   CREATE USER (username) FOR LOGIN (your login name)
   

Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader database role to read all tables.

USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'

FOR WINDOWS: (what has helped me)

This is the link I am referring to: https://qsartoolbox.org/content/documents/ResettingPostgreSQLPassword.pdf

1. Open your cmd and go to C:\Program Files\PostgreSQL\12\data This is usually the right path. You might have it stored somewhere else. Note that, if you have a different postgresql version, there will be a different number. That doesn't matter.

2. Find a pg_hba.conf file and copy it to somewhere else (That way you will have an unmodified version of this file, so you will be able to look at it after we make some changes)

3. Open pg_hba.conf file (not the backup, but the original)

4. Find the multiple lines that start with host near the bottom of the file:

   host all all 127.0.0.1/32 md5

   host all all ::1/128 md5

   host replication all 127.0.0.1/32 md5

   host replication all ::1/128 md5

5. Replace md5 with trust:

   host all all 127.0.0.1/32 trust

   host all all ::1/128 trust

   host replication all 127.0.0.1/32 trust

   host replication all ::1/128 trust

6. Close this file

7. Go to your search bar on windows and open Services app. Find postgres and restart it. picture of services app

8. Write cd.. in cmd and then cd bin. Your path should be C:\Program Files\PostgreSQL\12\bin

9. Enter: psql -U postgres -h localhost

10. Enter: ALTER USER postgres with password '<your new password>';Make sure that you include ; at the end “ALTER ROLE” should be displayed as an indication that the previous line was executed successfully

11. Open original pg_hba.conf file and change back from trust to md5

12. Restart the server with Services app as before

You might want to look into the DateTime.ToShortTimeString() method.

Also, there many other methods and properties on the DateTime object that can help you in formating the date or time in any way you like. Just take a look at the documentation.

increase the response.getBufferSize() get the buffer size and compare with the bytes you want to transfer !

2 GB by default. If the application is large address space aware (linked with /LARGEADDRESSAWARE), it gets 4 GB (not 3 GB, see http://msdn.microsoft.com/en-us/library/aa366778.aspx)

They're still limited to 2 GB since many application depends on the top bit of pointers to be zero.

This saved my day. The simplest approach to get the path from URI.

  //kotlin
  myuri = data.data
  val realPath = myuri.path
  Log.d(TAG, "path: $realPath")

Returns path :

 path: /storage/emulated/0/Download/CutOFF - Escuro (Original Mix).mp3

I like to make use of the css :before and a data-* attribute for the list

HTML:

<ul data-header="heading"> 
<li>list item </li>
<li>list item </li>
<li>list item </li>
</ul>

CSS:

ul:before{
    content:attr(data-header);
    font-size:120%;
    font-weight:bold;
    margin-left:-15px;
}

This will make a list with the header on it that is whatever text is specified as the list's data-header attribute. You can then easily style it to your needs.

I found the answer.

You can configure IE8 to display application/json in the browser window by updating the registry. There's no need for an external tool. I haven't tested this broadly, but it works with IE8 on Vista.

To use this, remember, all the usual caveats about updating the registry apply. Stop IE. Then, cut and paste the following into a file, by the name of json-ie.reg.

Windows Registry Editor Version 5.00
;
; Tell IE to open JSON documents in the browser.  
; 25336920-03F9-11cf-8FD0-00AA00686F13 is the CLSID for the "Browse in place" .
;  

[HKEY_CLASSES_ROOT\MIME\Database\Content Type\application/json]
"CLSID"="{25336920-03F9-11cf-8FD0-00AA00686F13}"
"Encoding"=hex:08,00,00,00

[HKEY_CLASSES_ROOT\MIME\Database\Content Type\text/json]
"CLSID"="{25336920-03F9-11cf-8FD0-00AA00686F13}"
"Encoding"=hex:08,00,00,00

Then double-click the .reg file. Restart IE. The new behavior you get when tickling a URL that returns a doc with Content-Type: application/json or Content-Type: text/json is like this:

What it does, why it works:

The 25336920-03F9-11cf-8FD0-00AA00686F13 is the CLSID for the "Browse in place" action. Basically this registry entry is telling IE that for docs that have a mime type of application/json, just view it in place. This won't affect any application/json documents downloaded via <script> tags, or via XHR, and so on.

The CLSID and Encoding keys get the same values used for image/gif, image/jpeg, and text/html.

This hint came from this site, and from Microsoft's article Handling MIME Types in Internet Explorer .

In FF, you don't need an external add-on either. You can just use the view-source: pseudo-protocol. Enter a URL like this into the address bar:

view-source:http://myserver/MyUrl/That/emits/Application/json

This pseudo-protocol used to be supported in IE, also, until WinXP-sp2, when Microsoft disabled it for security reasons.

while(rs.next())
  {
    if(f.exists() && !f.isDirectory())
      continue;  //then skip the iteration

     else
     {
     //proceed
     }
  }

Embedding a Google Drive directory in an IFRAME

Google Drive folders can be embedded and displayed in list and grid views (in which all you can do is click a file or folder to open it on a new tab). To do so, simply replace FOLDER-ID with your own in:

List view

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#list" style="width:100%; height:600px; border:0;"></iframe>

or without specifying a mode, since list mode is the default:

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID" style="width:100%; height:600px; border:0;"></iframe>

Grid view

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

Obtaining your folder id

The id is the hash (alphanumeric gibberish) after folders/ in the URL of the folder. You can see the URL in the address bar of your browser when you open the Drive folder. For example, in:

https://drive.google.com/drive/folders/0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2 

The Folder ID is 0B1iqp0kGPjWsNDg5NWFlZjEtN2IwZC00NmZiLWE3MjktYTE2ZjZjNTZiMDY2.

Folder with G Suite/Google Apps domain

If your folder is part of a Google Apps domain, you can add the domain to the URL to alleviate the permission problems (detailed further ahead):

<iframe src="https://drive.google.com/a/MY.DOMAIN.COM/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

Just replace MY.DOMAIN.COM and FOLDER-ID with your own.

Caveat with folders requiring permission

This technique works best for folders with public access. Folders that are shared only with certain Google accounts can cause trouble when you embed them this way, depending on which Google accounts are active on the user's browser:

1. If the user has not logged in to any Google account, then nothing appears in the frame.
2. If the user is logged onto an account without authorisation to access the folder, the frame will contain the message You need permission, with some buttons to Request access or Switch accounts, but if you click on this last, the frame blanks out.
3. If the user logs into an account without proper permissions, and later adds the authorised account, on loading the embedded Drive Google will resort to the first active account, and the user will see You need permission, unless...
4. If the URL contains a Google Suite domain, and the user is logged into that domain's account, the embedded view will work, even if the user logged to another account first.

The blank frames are because Google forbids embedding its login page in an IFRAME (presumably to prevent account stealing), via the X-Frame-Options header, which if set to SAMEORIGIN will cause any well-behaved browser to refuse to load the page if it's not in the same domain (v.g. drive.google.com). You can see this in the developer console of your browser.

TL;DR

To get a list or grid view of a Drive folder (in which all you can do is click a file or folder to open it on a new tab), use:

<iframe src="https://drive.google.com/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

or alternatively, for a Google Suite/Apps Drive:

<iframe src="https://drive.google.com/a/MY.DOMAIN.COM/embeddedfolderview?id=FOLDER-ID#grid" style="width:100%; height:600px; border:0;"></iframe>

Replace MY.DOMAIN.COM and FOLDER-ID with your own; remove #grid to get a detailed file list.

For private folders, have your users log to the correct account before loading the page with the embedded folder; if the folder is in a Google Apps domain, you can add the domain to the URL. Else, they must log into the authorised account before any other.

I recommend to use SMO (Enable TCP/IP Network Protocol for SQL Server). However, it was not available in my case.

I rewrote the WMI commands from Krzysztof Kozielczyk to PowerShell.

By pressing one arrow key getch will push three values into the buffer:

• '\033'
• '['
• 'A', 'B', 'C' or 'D'

So the code will be something like this:

if (getch() == '\033') { // if the first value is esc
    getch(); // skip the [
    switch(getch()) { // the real value
        case 'A':
            // code for arrow up
            break;
        case 'B':
            // code for arrow down
            break;
        case 'C':
            // code for arrow right
            break;
        case 'D':
            // code for arrow left
            break;
    }
}

Ahhhh, now it is clear. You seem to have problems binding back the value. Not with displaying it on the view. Indeed, that's the fault of the default model binder. You could write and use a custom one that will take into consideration the [DisplayFormat] attribute on your model. I have illustrated such a custom model binder here: https://stackoverflow.com/a/7836093/29407

Apparently some problems still persist. Here's my full setup working perfectly fine on both ASP.NET MVC 3 & 4 RC.

Model:

public class MyViewModel
{
    [DisplayName("date of birth")]
    [DataType(DataType.Date)]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}", ApplyFormatInEditMode = true)]
    public DateTime? Birth { get; set; }
}

Controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View(new MyViewModel
        {
            Birth = DateTime.Now
        });
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        return View(model);
    }
}

View:

@model MyViewModel

@using (Html.BeginForm())
{
    @Html.LabelFor(x => x.Birth)
    @Html.EditorFor(x => x.Birth)
    @Html.ValidationMessageFor(x => x.Birth)
    <button type="submit">OK</button>
}

Registration of the custom model binder in Application_Start:

ModelBinders.Binders.Add(typeof(DateTime?), new MyDateTimeModelBinder());

And the custom model binder itself:

public class MyDateTimeModelBinder : DefaultModelBinder
{
    public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
        var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);

        if (!string.IsNullOrEmpty(displayFormat) && value != null)
        {
            DateTime date;
            displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
            // use the format specified in the DisplayFormat attribute to parse the date
            if (DateTime.TryParseExact(value.AttemptedValue, displayFormat, CultureInfo.InvariantCulture, DateTimeStyles.None, out date))
            {
                return date;
            }
            else
            {
                bindingContext.ModelState.AddModelError(
                    bindingContext.ModelName,
                    string.Format("{0} is an invalid date format", value.AttemptedValue)
                );
            }
        }

        return base.BindModel(controllerContext, bindingContext);
    }
}

Now, no matter what culture you have setup in your web.config (<globalization> element) or the current thread culture, the custom model binder will use the DisplayFormat attribute's date format when parsing nullable dates.

Put all radio buttons for a group in a container object like a Panel or a GroupBox. That will automatically group them together in Windows Forms.

I believe that, if you need to use the %20 variant, you could perhaps use rawurlencode().

check this code from MainActivity

</category>

<!-- enable query logging for SQL statement parameter value -->
<category name="org.springframework.jdbc.core.StatementCreatorUtils">

checkip.dyndns.org is not always works correctly. For example, for my machine it shows internal after-NAT address:

Current IP Address: 192.168.1.120

I think its happening, because of I have my local DNS-zone behind NAT, and my browser sends to checkip its local IP address, which is returned back.

Also, http is heavy weight and text oriented TCP-based protocol, so not very suitable for quick and efficient regular request for external IP address. I suggest to use UDP-based, binary STUN, especially designed for this purposes:

http://en.wikipedia.org/wiki/STUN

STUN-server is like "UDP mirror". You looking to it, and see "how I looks".

There is many public STUN-servers over the world, where you can request your external IP. For example, see here:

http://www.voip-info.org/wiki/view/STUN

You can download any STUN-client library, from Internet, for example, here:

http://www.codeproject.com/Articles/18492/STUN-Client

And use it.

You can use Vue event system

vm.$broadcast('event-name', args)

and

 vm.$on('event-name', function())

Here is the fiddle: http://jsfiddle.net/hfalucas/wc1gg5v4/59/

You need to get a list of all the keys, loop over them and add them to your map as shown in the example below:

    String s = "{menu:{\"1\":\"sql\", \"2\":\"android\", \"3\":\"mvc\"}}";
    JSONObject jObject  = new JSONObject(s);
    JSONObject  menu = jObject.getJSONObject("menu");

    Map<String,String> map = new HashMap<String,String>();
    Iterator iter = menu.keys();
    while(iter.hasNext()){
        String key = (String)iter.next();
        String value = menu.getString(key);
        map.put(key,value);
    }

There are two obvious points, as well as the points in the other answer:

• They are exactly equivalent when using sub queries:

  SELECT * FROM table
  WHERE column IN(subquery);
  
  SELECT * FROM table
  WHERE column = ANY(subquery);
  

On the other hand:

• Only the IN operator allows a simple list:

  SELECT * FROM table
  WHERE column IN(… , … , …);
  

Presuming they are exactly the same has caught me out several times when forgetting that ANY doesn’t work with lists.

From the C# programming guide on MSDN:

The parameter of the Main method is a String array that represents the command-line arguments

So, if I had a program (MyApp.exe) like this:

class Program
{
  static void Main(string[] args)
  {
    foreach (var arg in args)
    {
      Console.WriteLine(arg);
    }
  }
}

That I started at the command line like this:

MyApp.exe Arg1 Arg2 Arg3

The Main method would be passed an array that contained three strings: "Arg1", "Arg2", "Arg3".

If you need to pass an argument that contains a space then wrap it in quotes. For example:

MyApp.exe "Arg 1" "Arg 2" "Arg 3"

Command line arguments commonly get used when you need to pass information to your application at runtime. For example if you were writing a program that copies a file from one location to another you would probably pass the two locations as command line arguments. For example:

Copy.exe C:\file1.txt C:\file2.txt

Use pgrep - available on many platforms:

kill -9 `pgrep -f cps_build`

pgrep -f will return all PIDs with coincidence "cps_build"

It turns out that the string needed to be turned into a bytearray and to do this I editted the code to

ser.write("%01#RDD0010000107**\r".encode())

This solved the problem

Swift 4

Setup your UIViewController with this extension method once e.g in viewDidLoad:

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

and the keyboard will be dismissed even by tapping on the NavigationBar.

import UIKit
extension UIViewController {
    /// Call this once to dismiss open keyboards by tapping anywhere in the view controller
    func setupHideKeyboardOnTap() {
        self.view.addGestureRecognizer(self.endEditingRecognizer())
        self.navigationController?.navigationBar.addGestureRecognizer(self.endEditingRecognizer())
    }

    /// Dismisses the keyboard from self.view
    private func endEditingRecognizer() -> UIGestureRecognizer {
        let tap = UITapGestureRecognizer(target: self.view, action: #selector(self.view.endEditing(_:)))
        tap.cancelsTouchesInView = false
        return tap
    }
}

When in doubt, read the documentation:

filename = "C:\Temp\vblist.txt"

Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)

Do Until f.AtEndOfStream
  WScript.Echo f.ReadLine
Loop

f.Close

You could try..

comm -13 <(sort file1) <(sort file2) > file3

or

grep -Fxvf file1 file2 > file3

or

diff file1 file2 | grep "<" | sed 's/^<//g'  > file3

or

join -v 2 <(sort file1) <(sort file2) > file3

None of these answers worked for me, at least not for scrolling down a facebook search result page, but I found after a lot of testing this solution:

while driver.find_element_by_tag_name('div'):
    driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
    Divs=driver.find_element_by_tag_name('div').text
    if 'End of Results' in Divs:
        print 'end'
        break
    else:
        continue

While I agree with Jörn's answer if your class conforms to the JavaBeabs spec, here is a good alternative if it doesn't and you use Spring.

Spring has a class named ReflectionUtils that offers some very powerful functionality, including doWithFields(class, callback), a visitor-style method that lets you iterate over a classes fields using a callback object like this:

public void analyze(Object obj){
    ReflectionUtils.doWithFields(obj.getClass(), field -> {

        System.out.println("Field name: " + field.getName());
        field.setAccessible(true);
        System.out.println("Field value: "+ field.get(obj));

    });
}

But here's a warning: the class is labeled as "for internal use only", which is a pity if you ask me

If you are using a MySql workbench, go to the home page of workbench, right click on your database, copy the JDBC connection string, and paste it into the Java program.

unfortunately we can't use in MySQL after INSERT or UPDATE description, like in Oracle

You can also try

  Calendar calendar = Calendar.getInstance();
  System.out.println(calendar.getTimeInMillis());

getTimeInMillis() - the current time as UTC milliseconds from the epoch

Run this command line on your preferred shell session:

db2 "select tabname from syscat.tables where owner = 'DB2INST1'"

Maybe you'd like to modify the owner name, and need to check the list of current owners?

db2 "select distinct owner from syscat.tables"

Use PHP Document Object Model:

<?php
   $str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
   $DOM = new DOMDocument;
   $DOM->loadHTML($str);

   //get all H1
   $items = $DOM->getElementsByTagName('h1');

   //display all H1 text
   for ($i = 0; $i < $items->length; $i++)
        echo $items->item($i)->nodeValue . "<br/>";
?>

This outputs as:

 T1
 T2
 T3

[EDIT]: After OP Clarification:

If you want the content like Lorem ipsum. etc, you can directly use this regex:

<?php
   $str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
   echo preg_replace("#<h1.*?>.*?</h1>#", "", $str);
?>

this outputs:

Lorem ipsum.The quick red fox...... jumps over the lazy brown FROG

Your query ($myQuery) is failing and therefore not producing a query resource, but instead producing FALSE.

To reveal what your dynamically generated query looks like and reveal the errors, try this:

$result2 = mysql_query($myQuery) or die($myQuery."<br/><br/>".mysql_error());

The error message will guide you to the solution, which from your comment below is related to using ORDER BY on a field that doesn't exist in the table you're SELECTing from.

You should be able to put them in your ~/matlab on unix.

I'm not sure which directory matlab looks in for windows, but you should be able to figure it out by executing userpath from the matlab command line.

You have two options:

1. Define a named class. Pass your parameter to the constructor of the named class.

2. Have your anonymous class close over your "parameter". Be sure to mark it as final.

You can try this:

ls -d $PWD/*

This URL (JMX-Console) should provide you the informations

The tomcat version is implied by the jboss server version.

EDIT:

A complete list of versions you find here VersionOfTomcatInJBossAS

Where you reach your JBoss depends on the interface it is bound, using -b hostname If you start using JBoss with -b 0.0.0.0 option. That way, you can access the system using localhost, machineName and even the IP address. By default it's localhost, if you use th -b option you need to replace localhost by yourhostname.

Below is how it's working for me on Python 3.6:

import requests
import urllib3

# Suppress InsecureRequestWarning: Unverified HTTPS
urllib3.disable_warnings()

The previous explanations are all overly detailed and complicated IMO. Put simply, OAuth 2 delegates security to the HTTPS protocol. OAuth 1 did not require this and consequentially had alternative methods to deal with various attacks. These methods required the application to engage in certain security protocols which are complicated and can be difficult to implement. Therefore, it is simpler to just rely on the HTTPS for security so that application developers dont need to worry about it.

As to your other questions, the answer depends. Some services dont want to require the use of HTTPS, were developed before OAuth 2, or have some other requirement which may prevent them from using OAuth 2. Furthermore, there has been a lot of debate about the OAuth 2 protocol itself. As you can see, Facebook, Google, and a few others each have slightly varying versions of the protocols implemented. So some people stick with OAuth 1 because it is more uniform across the different platforms. Recently, the OAuth 2 protocol has been finalized but we have yet to see how its adoption will take.

This will grab records with strings (in the fieldName column) that are 10 characters long:

 select * from table where length(fieldName)=10

You are simply sending signals to the processes. kill is a command to send those signals.

The keyboard command Ctrl+C sends a SIGINT, kill -9 sends a SIGKILL, and kill -15 sends a SIGTERM.

What signal do you want to send to your server to end it?

This how I do it in V3:

I start by loading the google maps api and within the callback method initialize() I load MarkerWithLabel.js that I found here:

function initialize() {

            $.getScript("/js/site/marker/MarkerWithLabel.js#{applicationBean.version}", function(){

            var mapOptions = {
                zoom: 8,
                center: new google.maps.LatLng(currentLat, currentLng),
                mapTypeId: google.maps.MapTypeId.ROADMAP,
                streetViewControl: false,
                mapTypeControl: false
            };

            var map = new google.maps.Map(document.getElementById('mapholder'),
                    mapOptions);

            var bounds = new google.maps.LatLngBounds();

            for (var i = 0; i < mapData.length; i++) {
                createMarker(i+1, map, mapData[i]); <!-- MARKERS! -->
                extendBounds(bounds, mapData[i]);
            }
            map.fitBounds(bounds);
            var maximumZoomLevel = 16;
            var minimumZoomLevel = 11;
            var ourZoom = defaultZoomLevel; // default zoom level

            var blistener = google.maps.event.addListener((map), 'bounds_changed', function(event) {
                if (this.getZoom(map.getBounds) &gt; 16) {
                    this.setZoom(maximumZoomLevel);
                }
                google.maps.event.removeListener(blistener);
            });
            });
        }

        function loadScript() {
            var script = document.createElement('script');
            script.type = 'text/javascript';
            script.src = "https://maps.googleapis.com/maps/api/js?v=3.exp&amp;libraries=places&amp;sensor=false&amp;callback=initialize";
            document.body.appendChild(script);
        }

        window.onload = loadScript;

    </script> 

I then create the markers with createMarker():

function createMarker(number, currentMap, currentMapData) {

   var marker = new MarkerWithLabel({
       position: new google.maps.LatLng(currentMapData[0], currentMapData[1]),
                 map: currentMap,
                 icon: '/img/sticker/empty.png',
                 shadow: '/img/sticker/bubble_shadow.png',
                 transparent: '/img/sticker/bubble_transparent.png',
                 draggable: false,
                 raiseOnDrag: false,
                 labelContent: ""+number,
                 labelAnchor: new google.maps.Point(3, 30),
                 labelClass: "mapIconLabel", // the CSS class for the label
                 labelInBackground: false
                });
            }

Since I added mapIconLabel class to the marker I can add some css rules in my css:

.mapIconLabel {
    font-size: 15px;
    font-weight: bold;
    color: #FFFFFF;
    font-family: 'DINNextRoundedLTProMediumRegular';
}

And here is the result:

Had the same question. The other answers don't seem to address why close() is really necessary? Also, Op seemed to be struggling to figure out the preferred way to work with HttpClient, et al.

According to Apache:

// The underlying HTTP connection is still held by the response object
// to allow the response content to be streamed directly from the network socket.
// In order to ensure correct deallocation of system resources
// the user MUST call CloseableHttpResponse#close() from a finally clause.

In addition, the relationships go as follows:

HttpClient (interface)

implemented by:

CloseableHttpClient - ThreadSafe.

DefaultHttpClient - ThreadSafe BUT deprecated, use HttpClientBuilder instead.

HttpClientBuilder - NOT ThreadSafe, BUT creates ThreadSafe CloseableHttpClient.

• Use to create CUSTOM CloseableHttpClient.

HttpClients - NOT ThreadSafe, BUT creates ThreadSafe CloseableHttpClient.

• Use to create DEFAULT or MINIMAL CloseableHttpClient.

The preferred way according to Apache:

CloseableHttpClient httpclient = HttpClients.createDefault();

The example they give does httpclient.close() in the finally clause, and also makes use of ResponseHandler as well.

As an alternative, the way mkyong does it is a bit interesting, as well:

HttpClient client = HttpClientBuilder.create().build();

He doesn't show a client.close() call but I would think it is necessary, since client is still an instance of CloseableHttpClient.

Okay I fixed this thing. Had to first convert the projects to Maven Projects, then remove them from the Eclipse workspace, and then re-import them.

Great response by Jim Morris, I stumbled upon this and it took me a while to figure. Here is some simple code that shows that after submitting a "request" for a unique_lock boost (version 1.54) blocks all shared_lock requests. This is very interesting as it seems to me that choosing between unique_lock and upgradeable_lock allows if we want write priority or no priority.

Also (1) in Jim Morris's post seems to contradict this: Boost shared_lock. Read preferred?

#include <iostream>
#include <boost/thread.hpp>

using namespace std;

typedef boost::shared_mutex Lock;
typedef boost::unique_lock< Lock > UniqueLock;
typedef boost::shared_lock< Lock > SharedLock;

Lock tempLock;

void main2() {
    cout << "10" << endl;
    UniqueLock lock2(tempLock); // (2) queue for a unique lock
    cout << "11" << endl;
    boost::this_thread::sleep(boost::posix_time::seconds(1));
    lock2.unlock();
}

void main() {
    cout << "1" << endl;
    SharedLock lock1(tempLock); // (1) aquire a shared lock
    cout << "2" << endl;
    boost::thread tempThread(main2);
    cout << "3" << endl;
    boost::this_thread::sleep(boost::posix_time::seconds(3));
    cout << "4" << endl;
    SharedLock lock3(tempLock); // (3) try getting antoher shared lock, deadlock here
    cout << "5" << endl;
    lock1.unlock();
    lock3.unlock();
}

Its Got simpler with Android Studio All you need is to first choose

1. import project(eclipse.....)
2. then choose your folder eclipse based project.like this one below

3.based on the type of project and library you used like (ActionBarSherlock) you may prompted special import wizard so go ahead and click next then finish. in this case it was simple one

4.And you are done.

but sometimes the debug or Run options do not work and a error msg shows like

"this project structure is not gradle based or migrate it to gradle"

something to solve this close the opened eclipse project and reopen same project through the same process as we did before with import project (eclipse adt,gradle,etc)) this time android studio gonna add all necessary gradle files and green debug option will work too. i have did this somehow accidentally but it worked, i just hope it works for you too.

this simple script worked for me.

<?php

foreach($_FILES as $file){
  //echo $file['name']; 
  echo $file['tmp_name'].'</br>'; 
  move_uploaded_file($file['tmp_name'], "./uploads/".$file["name"]);
}

?>

You can grant permissions on a view and not the base table. This is one of the reasons people like using views.

Have a look here: GRANT Object Permissions (Transact-SQL)

You define a DELIMITER to tell the mysql client to treat the statements, functions, stored procedures or triggers as an entire statement. Normally in a .sql file you set a different DELIMITER like $$. The DELIMITER command is used to change the standard delimiter of MySQL commands (i.e. ;). As the statements within the routines (functions, stored procedures or triggers) end with a semi-colon (;), to treat them as a compound statement we use DELIMITER. If not defined when using different routines in the same file or command line, it will give syntax error.

Note that you can use a variety of non-reserved characters to make your own custom delimiter. You should avoid the use of the backslash (\) character because that is the escape character for MySQL.

DELIMITER isn't really a MySQL language command, it's a client command.

Example

DELIMITER $$

/*This is treated as a single statement as it ends with $$ */
DROP PROCEDURE IF EXISTS `get_count_for_department`$$

/*This routine is a compound statement. It ends with $$ to let the mysql client know to execute it as a single statement.*/ 
CREATE DEFINER=`student`@`localhost` PROCEDURE `get_count_for_department`(IN the_department VARCHAR(64), OUT the_count INT)
BEGIN
    
    SELECT COUNT(*) INTO the_count FROM employees where department=the_department;

A big part of the REST philosophy is to exploit as many standard features of the HTTP protocol as possible when designing your API. Applying that philosophy to authentication, client and server would utilize standard HTTP authentication features in the API.

Login screens are great for human user use cases: visit a login screen, provide user/password, set a cookie, client provides that cookie in all future requests. Humans using web browsers can't be expected to provide a user id and password with each individual HTTP request.

But for a REST API, a login screen and session cookies are not strictly necessary, since each request can include credentials without impacting a human user; and if the client does not cooperate at any time, a 401 "unauthorized" response can be given. RFC 2617 describes authentication support in HTTP.

TLS (HTTPS) would also be an option, and would allow authentication of the client to the server (and vice versa) in every request by verifying the public key of the other party. Additionally this secures the channel for a bonus. Of course, a keypair exchange prior to communication is necessary to do this. (Note, this is specifically about identifying/authenticating the user with TLS. Securing the channel by using TLS / Diffie-Hellman is always a good idea, even if you don't identify the user by its public key.)

An example: suppose that an OAuth token is your complete login credentials. Once the client has the OAuth token, it could be provided as the user id in standard HTTP authentication with each request. The server could verify the token on first use and cache the result of the check with a time-to-live that gets renewed with each request. Any request requiring authentication returns 401 if not provided.

Use .lower() - For example:

s = "Kilometer"
print(s.lower())

The official 2.x documentation is here: str.lower()
The official 3.x documentation is here: str.lower()

Are you sure it is smaller?

Bitmap original = BitmapFactory.decodeStream(getAssets().open("1024x768.jpg"));
ByteArrayOutputStream out = new ByteArrayOutputStream();
original.compress(Bitmap.CompressFormat.PNG, 100, out);
Bitmap decoded = BitmapFactory.decodeStream(new ByteArrayInputStream(out.toByteArray()));

Log.e("Original   dimensions", original.getWidth()+" "+original.getHeight());
Log.e("Compressed dimensions", decoded.getWidth()+" "+decoded.getHeight());

Gives

12-07 17:43:36.333: E/Original   dimensions(278): 1024 768
12-07 17:43:36.333: E/Compressed dimensions(278): 1024 768

Maybe you get your bitmap from a resource, in which case the bitmap dimension will depend on the phone screen density

Bitmap bitmap=((BitmapDrawable)getResources().getDrawable(R.drawable.img_1024x768)).getBitmap();
Log.e("Dimensions", bitmap.getWidth()+" "+bitmap.getHeight());

12-07 17:43:38.733: E/Dimensions(278): 768 576

The asterisk (*) means "zero or more of the previous item".

If you want to match any single character use

sed -i 's/string-./string-0/g' file.txt

If you want to match any string (i.e. any single character zero or more times) use

sed -i 's/string-.*/string-0/g' file.txt

One more way:

CREATE OR REPLACE TYPE TYPE_TABLE_OF_VARCHAR2 AS TABLE OF VARCHAR(100);
-- ...
SELECT field1, field2, field3
  FROM table1
  WHERE name IN (
    SELECT * FROM table (SELECT CAST(? AS TYPE_TABLE_OF_VARCHAR2) FROM dual)
  );

I don't consider it's optimal, but it works. The hint /*+ CARDINALITY(...) */ would be very useful because Oracle does not understand cardinality of the array passed and can't estimate optimal execution plan.

As another alternative - batch insert into temporary table and using the last in subquery for IN predicate.

RewriteEngine On

RewriteRule ^(wordpress)($|/) - [L]

You can achieve that by setting the colors alpha channel.

The color scheme is like this #AARRGGBB there A stands for alpha channel(transparency), R stands for red, G for green and B for blue.

To delete rows empty in table

syntax:

DELETE FROM table_name 
WHERE column_name IS NULL;

example:

Table name: data ---> column name: pkdno

DELETE FROM data 
WHERE pkdno IS NULL;

Answer: 5 rows deleted. (sayso)

I know of plotyy that allows you to have two y-axes, but no "plotyyy"!

Perhaps you can normalize the y values to have the same scale (min/max normalization, zscore standardization, etc..), then you can just easily plot them using normal plot, hold sequence.

Here's an example:

%# random data
x=1:20;
y = [randn(20,1)*1 + 0 , randn(20,1)*5 + 10 , randn(20,1)*0.3 + 50];

%# plotyy
plotyy(x,y(:,1), x,y(:,3))

%# orginial
figure
subplot(221), plot(x,y(:,1), x,y(:,2), x,y(:,3))
title('original'), legend({'y1' 'y2' 'y3'})

%# normalize: (y-min)/(max-min) ==> [0,1]
yy = bsxfun(@times, bsxfun(@minus,y,min(y)), 1./range(y));
subplot(222), plot(x,yy(:,1), x,yy(:,2), x,yy(:,3))
title('minmax')

%# standarize: (y - mean) / std ==> N(0,1)
yy = zscore(y);
subplot(223), plot(x,yy(:,1), x,yy(:,2), x,yy(:,3))
title('zscore')

%# softmax normalization with logistic sigmoid ==> [0,1]
yy = 1 ./ ( 1 + exp( -zscore(y) ) );
subplot(224), plot(x,yy(:,1), x,yy(:,2), x,yy(:,3))
title('softmax')

If you want to start search from root "/" , you will probably see output somethings like:

find: /./proc/1731/fdinfo: Permission denied
find: /./proc/2032/task/2032/fd: Permission denied

It's because of permission. To solve this:

1. You can use sudo command:

   sudo find /. -name 'toBeSearched.file'
   

It asks super user's password, when enter the password you will see result what you really want. If you don't have permission to use sudo command which means you don't have super user's password, first ask system admin to add you to the sudoers file.

2. You can use redirect the Standard Error Output from (Generally Display/Screen) to some file and avoid seeing the error messages on the screen! redirect to a special file /dev/null :

   find /. -name 'toBeSearched.file' 2>/dev/null
   

3. You can use redirect the Standard Error Output from (Generally Display/Screen) to Standard output (Generally Display/Screen), then pipe with grep command with -v "invert" parameter to not to see the output lines which has 'Permission denied' word pairs:

   find /. -name 'toBeSearched.file' 2>&1 | grep -v 'Permission denied'
   

Nginx needs to run by command 'sudo /etc/init.d/nginx start'

VBA does not have an internal implementation of a dictionary, but from VBA you can still use the dictionary object from MS Scripting Runtime Library.

Dim d
Set d = CreateObject("Scripting.Dictionary")
d.Add "a", "aaa"
d.Add "b", "bbb"
d.Add "c", "ccc"

If d.Exists("c") Then
    MsgBox d("c")
End If

As you will see in linked discussion there is no need for initializing char with special character as it's done for us and is represented by '\u0000' character code.

So if we want simply to check if specified char was initialized just write:

if(charVariable != '\u0000'){
 actionsOnInitializedCharacter();
}

Link to question: what's the default value of char?

WebpackDevServer localhost from iphone

If you are using an app which is running on node. you can use webpack as a build tool and use their built in devserver

You can use webpackdevserver to start your application from a localhost server and then pass in your localhost address and port of your choice.

webpack-dev-server --host 192.168.0.89 --port 3000

then from your iPhone you can access it using

http://192.168.2.89:3000

Note :: Your laptop and iPhone should be on the same network, and you should use your localhost ip address.

For Mac how to find ip address you can refer Get local IP address in node.js

The print statement in Python converts its arguments to strings, and outputs those strings to stdout. To save the string to a variable instead, only convert it to a string:

a = str(tag.getArtist())

You need to use css-loader when creating bundle with webpack.

Install it:

npm install css-loader --save-dev

And add it to loaders in your webpack configs:

module.exports = {
  module: {
    loaders: [
      { test: /\.css$/, loader: "style-loader!css-loader" },
      // ...
    ]
  }
};

After this, you will be able to include css files in js.

@Cybernate, I was looking for the same script today thanks for your input. However I changed it just a bit for jQuery...

function clock(){
    $('body').prepend('<div id="clock"><label id="minutes">00</label>:<label id="seconds">00</label></div>');
         var totalSeconds = 0;
        setInterval(setTime, 1000);
        function setTime()
        {
            ++totalSeconds;
            $('#clock > #seconds').html(pad(totalSeconds%60));
            $('#clock > #minutes').html(pad(parseInt(totalSeconds/60)));
        }
        function pad(val)
        {
            var valString = val + "";
            if(valString.length < 2)
            {
                return "0" + valString;
            }
            else
            {
                return valString;
            }
        }
}
$(document).ready(function(){
    clock();
    });

the css part:

<style>
#clock {
    padding: 10px;
    position:absolute;
    top: 0px;
    right: 0px;
    color: black;
}
</style>

Because SQL Server performs integer division. Try this:

select 1 * 1.0 / 3

This is helpful when you pass integers as params.

select x * 1.0 / y

Value exactly equal to 123:

jQuery("#attached_docs[value='123']")

Full reference: http://api.jquery.com/category/selectors/

<a id="topbutton" href="#top">first page </a>

Basically what you have to do is replace the " #top" with the id of the first section or your page, or it could be the nav... Any id locate in the first part of the page and then try to set some style with css!

In Rails, you can do:

Dir[Rails.root.join('lib', 'ext', '*.rb')].each { |file| require file }

Update: Corrected with suggestion of @Jiggneshh Gohel to remove slashes.

You could do:

return_it(){

    eval ${FUNCNAME[1]}_r_val="\$1"

}

and then use it in your functions like this:

fun1(){
    return_it 34
}

fun2(){
    fun1; echo $fun1_r_val
}

My solution for replacing ${variable} style tokens (inspired by the answers here and by the Spring UriTemplate):

public static String substituteVariables(String template, Map<String, String> variables) {
    Pattern pattern = Pattern.compile("\\$\\{(.+?)\\}");
    Matcher matcher = pattern.matcher(template);
    // StringBuilder cannot be used here because Matcher expects StringBuffer
    StringBuffer buffer = new StringBuffer();
    while (matcher.find()) {
        if (variables.containsKey(matcher.group(1))) {
            String replacement = variables.get(matcher.group(1));
            // quote to work properly with $ and {,} signs
            matcher.appendReplacement(buffer, replacement != null ? Matcher.quoteReplacement(replacement) : "null");
        }
    }
    matcher.appendTail(buffer);
    return buffer.toString();
}

I've made an Int type extension. tested it in playground, hope this is useful. It also accepts negative ranges:

extension Int
{
    static func random(range: Range<Int> ) -> Int
    {
        var offset = 0

        if range.startIndex < 0   // allow negative ranges
        {
            offset = abs(range.startIndex)
        }

        let mini = UInt32(range.startIndex + offset)
        let maxi = UInt32(range.endIndex   + offset)

        return Int(mini + arc4random_uniform(maxi - mini)) - offset
    }
}

use like

var aRandomInt = Int.random(-500...100)  // returns a random number within the given range.

or define it as a Range extension as property like this:

extension Range
{
    var randomInt: Int
    {
        get
        {
            var offset = 0

            if (startIndex as Int) < 0   // allow negative ranges
            {
                offset = abs(startIndex as Int)
            }

            let mini = UInt32(startIndex as Int + offset)
            let maxi = UInt32(endIndex   as Int + offset)

            return Int(mini + arc4random_uniform(maxi - mini)) - offset
        }
    }
}

// usage example: get an Int within the given Range:
let nr = (-1000 ... 1100).randomInt

This solution is for Vue-2 users:

1. In vue-2 if you don't like to keep your files in static folder (relevant info), or
2. In vue-2 & vue-cli-3 if you don't like to keep your files in public folder (static folder is renamed to public):

The simple solution is :)

<img src="@/assets/img/clear.gif" /> // just do this:
<img :src="require(`@/assets/img/clear.gif`)" // or do this:
<img :src="require(`@/assets/img/${imgURL}`)" // if pulling from: data() {return {imgURL: 'clear.gif'}}

If you like to keep your static images in static/assets/img or public/assets/img folder, then just do:

<img src="./assets/img/clear.gif" />
<img src="/assets/img/clear.gif" /> // in some case without dot ./

For Active Directory users, an alternative way to do this would be -- assuming all your groups are stored in OU=Groups,DC=CorpDir,DC=QA,DC=CorpName -- to use the query (&(objectCategory=group)(CN=GroupCN)). This will work well for all groups with less than 1500 members. If you want to list all members of a large AD group, the same query will work, but you'll have to use ranged retrieval to fetch all the members, 1500 records at a time.

The key to performing ranged retrievals is to specify the range in the attributes using this syntax: attribute;range=low-high. So to fetch all members of an AD Group with 3000 members, first run the above query asking for the member;range=0-1499 attribute to be returned, then for the member;range=1500-2999 attribute.

You could use the Python bindings to libmagic, python-magic and then check the mime types. This won't tell you if the files are corrupted or intact but it should be able to determine what type of image it is.

Try this,

$('textarea#textarea_id').val(" ");

It's better to avoid unnecessary autoboxing for 2 reasons.

For one thing, it's a bit slower than int < int, as you're (sometimes) creating an extra object;

void doSomethingWith(Integer integerObject){ ...
  int i = 1000;
  doSomethingWith(i);//gets compiled into doSomethingWith(Integer.valueOf(i));

The bigger issue is that hidden autoboxing can hide exceptions:

void doSomethingWith (Integer count){
  if (count>0)  // gets compiled into count.intValue()>0

Calling this method with null will throw a NullPointerException.

The split between primitives and wrapper objects in java was always described as a kludge for speed. Autoboxing almost hides this, but not quite - it's cleaner just to keep track of the type. So if you've got an Integer object, you can just call compare() or intValue(), and if you've got the primitive just check the value directly.

String fname = "Sam\u0025";

PreparedStatement ps= conn.prepareStatement("SELECT * FROM Users WHERE User_FirstName LIKE ? ");

ps.setString(1, fname);

try the following snippet

const renObjData = this.props.data.map(function(data, idx) {
    return <ul key={idx}>{$.map(data,(val,ind) => {
        return (<li>{val}</li>);
    }
    }</ul>;
});

This technique is usually used for multiple axis in a figure. In this context it is often required to have a colorbar that corresponds in size with the result from imshow. This can be achieved easily with the axes grid tool kit:

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable

data = np.arange(100, 0, -1).reshape(10, 10)

fig, ax = plt.subplots()
divider = make_axes_locatable(ax)
cax = divider.append_axes('right', size='5%', pad=0.05)

im = ax.imshow(data, cmap='bone')

fig.colorbar(im, cax=cax, orientation='vertical')
plt.show()

I just spent a lot of time trying to understand what was wrong on my code too...

And it seems to be simple if you are using windows.

When you name your file "blabla.txt" then windows name it "blabla.txt.txt"... That's the same with .CSV files so windows create a file named "001.csv.csv" if you called it "001.csv"

So, when you create your .csv file, just rename it "001" and open it in R using read.table("/absolute/path/of/directory/with/required/001.csv")

It works for me.

These are simply ideas I've had thinking about the problem, never tried it but I like thinking about problems like this!

Before you begin

Consider normalising the pictures, if one is a higher resolution than the other, consider the option that one of them is a compressed version of the other, therefore scaling the resolution down might provide more accurate results.

Consider scanning various prospective areas of the image that could represent zoomed portions of the image and various positions and rotations. It starts getting tricky if one of the images are a skewed version of another, these are the sort of limitations you should identify and compromise on.

Matlab is an excellent tool for testing and evaluating images.

Testing the algorithms

You should test (at the minimum) a large human analysed set of test data where matches are known beforehand. If for example in your test data you have 1,000 images where 5% of them match, you now have a reasonably reliable benchmark. An algorithm that finds 10% positives is not as good as one that finds 4% of positives in our test data. However, one algorithm may find all the matches, but also have a large 20% false positive rate, so there are several ways to rate your algorithms.

The test data should attempt to be designed to cover as many types of dynamics as possible that you would expect to find in the real world.

It is important to note that each algorithm to be useful must perform better than random guessing, otherwise it is useless to us!

You can then apply your software into the real world in a controlled way and start to analyse the results it produces. This is the sort of software project which can go on for infinitum, there are always tweaks and improvements you can make, it is important to bear that in mind when designing it as it is easy to fall into the trap of the never ending project.

Colour Buckets

With two pictures, scan each pixel and count the colours. For example you might have the 'buckets':

white
red
blue
green
black

(Obviously you would have a higher resolution of counters). Every time you find a 'red' pixel, you increment the red counter. Each bucket can be representative of spectrum of colours, the higher resolution the more accurate but you should experiment with an acceptable difference rate.

Once you have your totals, compare it to the totals for a second image. You might find that each image has a fairly unique footprint, enough to identify matches.

Edge detection

How about using Edge Detection.
_{(source: wikimedia.org)}

With two similar pictures edge detection should provide you with a usable and fairly reliable unique footprint.

Take both pictures, and apply edge detection. Maybe measure the average thickness of the edges and then calculate the probability the image could be scaled, and rescale if necessary. Below is an example of an applied Gabor Filter (a type of edge detection) in various rotations.

Compare the pictures pixel for pixel, count the matches and the non matches. If they are within a certain threshold of error, you have a match. Otherwise, you could try reducing the resolution up to a certain point and see if the probability of a match improves.

Regions of Interest

Some images may have distinctive segments/regions of interest. These regions probably contrast highly with the rest of the image, and are a good item to search for in your other images to find matches. Take this image for example:

_{(source: meetthegimp.org)}

The construction worker in blue is a region of interest and can be used as a search object. There are probably several ways you could extract properties/data from this region of interest and use them to search your data set.

If you have more than 2 regions of interest, you can measure the distances between them. Take this simplified example:

_{(source: per2000.eu)}

We have 3 clear regions of interest. The distance between region 1 and 2 may be 200 pixels, between 1 and 3 400 pixels, and 2 and 3 200 pixels.

Search other images for similar regions of interest, normalise the distance values and see if you have potential matches. This technique could work well for rotated and scaled images. The more regions of interest you have, the probability of a match increases as each distance measurement matches.

It is important to think about the context of your data set. If for example your data set is modern art, then regions of interest would work quite well, as regions of interest were probably designed to be a fundamental part of the final image. If however you are dealing with images of construction sites, regions of interest may be interpreted by the illegal copier as ugly and may be cropped/edited out liberally. Keep in mind common features of your dataset, and attempt to exploit that knowledge.

Morphing

Morphing two images is the process of turning one image into the other through a set of steps:

Note, this is different to fading one image into another!

There are many software packages that can morph images. It's traditionaly used as a transitional effect, two images don't morph into something halfway usually, one extreme morphs into the other extreme as the final result.

Why could this be useful? Dependant on the morphing algorithm you use, there may be a relationship between similarity of images, and some parameters of the morphing algorithm.

In a grossly over simplified example, one algorithm might execute faster when there are less changes to be made. We then know there is a higher probability that these two images share properties with each other.

This technique could work well for rotated, distorted, skewed, zoomed, all types of copied images. Again this is just an idea I have had, it's not based on any researched academia as far as I am aware (I haven't look hard though), so it may be a lot of work for you with limited/no results.

Zipping

Ow's answer in this question is excellent, I remember reading about these sort of techniques studying AI. It is quite effective at comparing corpus lexicons.

One interesting optimisation when comparing corpuses is that you can remove words considered to be too common, for example 'The', 'A', 'And' etc. These words dilute our result, we want to work out how different the two corpus are so these can be removed before processing. Perhaps there are similar common signals in images that could be stripped before compression? It might be worth looking into.

Compression ratio is a very quick and reasonably effective way of determining how similar two sets of data are. Reading up about how compression works will give you a good idea why this could be so effective. For a fast to release algorithm this would probably be a good starting point.

Transparency

Again I am unsure how transparency data is stored for certain image types, gif png etc, but this will be extractable and would serve as an effective simplified cut out to compare with your data sets transparency.

Inverting Signals

An image is just a signal. If you play a noise from a speaker, and you play the opposite noise in another speaker in perfect sync at the exact same volume, they cancel each other out.

_{(source: themotorreport.com.au)}

Invert on of the images, and add it onto your other image. Scale it/loop positions repetitively until you find a resulting image where enough of the pixels are white (or black? I'll refer to it as a neutral canvas) to provide you with a positive match, or partial match.

However, consider two images that are equal, except one of them has a brighten effect applied to it:

_{(source: mcburrz.com)}

Inverting one of them, then adding it to the other will not result in a neutral canvas which is what we are aiming for. However, when comparing the pixels from both original images, we can definatly see a clear relationship between the two.

I haven't studied colour for some years now, and am unsure if the colour spectrum is on a linear scale, but if you determined the average factor of colour difference between both pictures, you can use this value to normalise the data before processing with this technique.

Tree Data structures

At first these don't seem to fit for the problem, but I think they could work.

You could think about extracting certain properties of an image (for example colour bins) and generate a huffman tree or similar data structure. You might be able to compare two trees for similarity. This wouldn't work well for photographic data for example with a large spectrum of colour, but cartoons or other reduced colour set images this might work.

This probably wouldn't work, but it's an idea. The trie datastructure is great at storing lexicons, for example a dictionarty. It's a prefix tree. Perhaps it's possible to build an image equivalent of a lexicon, (again I can only think of colours) to construct a trie. If you reduced say a 300x300 image into 5x5 squares, then decompose each 5x5 square into a sequence of colours you could construct a trie from the resulting data. If a 2x2 square contains:

FFFFFF|000000|FDFD44|FFFFFF

We have a fairly unique trie code that extends 24 levels, increasing/decreasing the levels (IE reducing/increasing the size of our sub square) may yield more accurate results.

Comparing trie trees should be reasonably easy, and could possible provide effective results.

More ideas

I stumbled accross an interesting paper breif about classification of satellite imagery, it outlines:

Texture measures considered are: cooccurrence matrices, gray-level differences, texture-tone analysis, features derived from the Fourier spectrum, and Gabor filters. Some Fourier features and some Gabor filters were found to be good choices, in particular when a single frequency band was used for classification.

It may be worth investigating those measurements in more detail, although some of them may not be relevant to your data set.

Other things to consider

There are probably a lot of papers on this sort of thing, so reading some of them should help although they can be very technical. It is an extremely difficult area in computing, with many fruitless hours of work spent by many people attempting to do similar things. Keeping it simple and building upon those ideas would be the best way to go. It should be a reasonably difficult challenge to create an algorithm with a better than random match rate, and to start improving on that really does start to get quite hard to achieve.

Each method would probably need to be tested and tweaked thoroughly, if you have any information about the type of picture you will be checking as well, this would be useful. For example advertisements, many of them would have text in them, so doing text recognition would be an easy and probably very reliable way of finding matches especially when combined with other solutions. As mentioned earlier, attempt to exploit common properties of your data set.

Combining alternative measurements and techniques each that can have a weighted vote (dependant on their effectiveness) would be one way you could create a system that generates more accurate results.

If employing multiple algorithms, as mentioned at the begining of this answer, one may find all the positives but have a false positive rate of 20%, it would be of interest to study the properties/strengths/weaknesses of other algorithms as another algorithm may be effective in eliminating false positives returned from another.

Be careful to not fall into attempting to complete the never ending project, good luck!

You can use this code to add placeholder attr for every TextInput field in you form. Text for placeholders will be taken from model field labels.

class PlaceholderDemoForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(PlaceholderDemoForm, self).__init__(*args, **kwargs)
        for field_name in self.fields:
            field = self.fields.get(field_name)  
            if field:
                if type(field.widget) in (forms.TextInput, forms.DateInput):
                    field.widget = forms.TextInput(attrs={'placeholder': field.label})

    class Meta:
        model = DemoModel

The best way in browsers that support it, is to send the file as a Blob, or using FormData if you want a multipart form. You do not need a FileReader for that. This is both simpler and more efficient than trying to read the data.

If you specifically want to send it as multipart/form-data, you can use a FormData object:

var xmlHttpRequest = new XMLHttpRequest();
xmlHttpRequest.open("POST", '/pushfile', true);
var formData = new FormData();
// This should automatically set the file name and type.
formData.append("file", file);
// Sending FormData automatically sets the Content-Type header to multipart/form-data
xmlHttpRequest.send(formData);

You can also send the data directly, instead of using multipart/form-data. See the documentation. Of course, this will need a server-side change as well.

// file is an instance of File, e.g. from a file input.
var xmlHttpRequest = new XMLHttpRequest();
xmlHttpRequest.open("POST", '/pushfile', true);

xmlHttpRequest.setRequestHeader("Content-Type", file.type);

// Send the binary data.
// Since a File is a Blob, we can send it directly.
xmlHttpRequest.send(file);

For browser support, see: http://caniuse.com/#feat=xhr2 (most browsers, including IE 10+).

I resolved this by just running a simple:

git pull

Nothing more. Now it's showing:

# On branch master

Only JWT's privateKey, which is on your server will decrypt the encrypted JWT. Those who know the privateKey will be able to decrypt the encrypted JWT.

Hide the privateKey in a secure location in your server and never tell anyone the privateKey.

It was mentioned as a comment by @henri-chan, but I think it deserves some more attention:

When you update the content of an element with new html using jQuery/javascript, and this new html contains <script> tags, those are executed synchronously and thus triggering this error. Same goes for stylesheets.

You know this is happening when you see (multiple) scripts or stylesheets being loaded as XHR in the console window. (firefox).

Depending on the structure of the string, you can use lstrip:

str = str.lstrip(':')

But this would remove all colons at the beginning, i.e. if you have ::foo, the result would be foo. But this function is helpful if you also have strings that do not start with a colon and you don't want to remove the first character then.

And one more....

var _e = $(e.target); // e being the event triggered
var element = _e.parent(); // the element the event was triggered on
console.log("_E " + element.context); // [object HTMLInputElement]
console.log("_E FORM " + element.context.form); // [object HTMLFormElement]
console.log("_E FORM " + element.context.form.id); // form id

in regards to:

Take a look at the open source WordPress application. They have a very re-usable window they have created for displaying an "activity in progress" type display over top of whatever view your application is currently displaying.

note that if you do utilise this code you MUST provide ALL the sourcecode to your own application to any user that requests it. You need to be aware that they may decide to repackage your code and sell it on the store themselves. This is all provided for under the terms of the GNU General Public License (GPL).

If you don't want to be forced into opening your sourcecode then you cannot use anything from the wordpress iphone application including the, referenced activity progress window, without forcing the GPL to apply to your own.

Field[] field = model.getClass().getDeclaredFields();     

for(int j=0 ; j<field.length ; j++){    
            String name = field[j].getName();                
            name = name.substring(0,1).toUpperCase()+name.substring(1); 
            String type = field[j].getGenericType().toString();    
            if(type.equals("class java.lang.String")){   
                Method m = model.getClass().getMethod("get"+name);
                String value = (String) m.invoke(model);    
                if(value == null){
                   ... something to do...
                }
}

The s/// command in sed allows you to use other characters instead of / as the delimiter, as in

sed 's#"http://www\.fubar\.com"#URL_FUBAR#g'

or

sed 's,"http://www\.fubar\.com",URL_FUBAR,g'

The double quotes are not a problem. For matching single quotes, switch the two types of quotes around. Note that a single quoted string may not contain single quotes (not even escaped ones).

The dots need to be escaped if sed is to interpret them as literal dots and not as the regular expression pattern . which matches any one character.

@macro-ferrari I did find a way to shorten it, and without look aheads in the light of all recent talks about regex engines

const LAT_RE = /^[+-]?(([1-8]?[0-9])(\.[0-9]{1,6})?|90(\.0{1,6})?)$/;

const LONG_RE = /^[+-]?((([1-9]?[0-9]|1[0-7][0-9])(\.[0-9]{1,6})?)|180(\.0{1,6})?)$/;

onClose: function(selectedDate) {

    $("#dpTodate").datepicker("option", "minDate", selectedDate);
    var maxDate = new Date(selectedDate);

     maxDate.setDate(maxDate.getDate() + 6); //6 days extra in from date

     $("#dpTodate").datepicker("option", "maxDate", maxDate);
}

You can even chain doReturn() method invocations like this

doReturn(null).doReturn(anotherInstance).when(mock).method();

cute isn't it :)

if needed programmatic from a PDE or JDT code:

public static void setWorkspaceAutoBuild(boolean flag) throws CoreException 
{
IWorkspace workspace = ResourcesPlugin.getWorkspace();
final IWorkspaceDescription description = workspace.getDescription();
description.setAutoBuilding(flag);
workspace.setDescription(description);
}

This seems to be what you're looking for:

g <- ggplot(x, aes(reorder(variable, value), value))
g + geom_bar() + scale_y_continuous(formatter="percent") + coord_flip()

The reorder() function will reorder your x axis items according to the value of variable.

I had a similar problem with pip and easy_install:

Cannot fetch index base URL https://pypi.python.org/simple/

As suggested in the referenced blog post, there must be an issue with some older versions of OpenSSL being incompatible with pip 1.3.1.

Installing pip-1.2.1 is a working workaround.

Possibly related question.

[Edit]:

This definitely happens in RHEL/CentOS 4 distros

For encoding/decoding numbers to/from byte sequences, there's the encoding/binary package. There are examples in the documentation: see the Examples section in the table of contents.

These encoding functions operate on io.Writer interfaces. The net.TCPConn type implements io.Writer, so you can write/read directly to network connections.

If you've got a Go program on either side of the connection, you may want to look at using encoding/gob. See the article "Gobs of data" for a walkthrough of using gob (skip to the bottom to see a self-contained example).

Bash -ge 4 has the mapfile builtin to read lines from the standard input into an array variable.

help mapfile 

mapfile < file.txt lines
printf "%s" "${lines[@]}"

mapfile -t < file.txt lines    # strip trailing newlines
printf "%s\n" "${lines[@]}" 

See also:

http://bash-hackers.org/wiki/doku.php/commands/builtin/mapfile

#include <math.h>


printf ("%d", (int) pow (3, 4));

I think your assignment is backwards:

a[i] = b[i];

should be:

b[i] = a[i];

    header("Content-Transfer-Encoding: Binary");
    header("Content-Length:".filesize($attachment_location));
    header("Content-Disposition: attachment; filename=filePath");
    readfile($attachment_location);
    die();
} else {
    die("Error: File not found.");
}

   public string Path { get; set; }

<sup> and <sub> tags work and are your only good solution for arbitrary text. Other solutions include:

Unicode

If the superscript (or subscript) you need is of a mathematical nature, Unicode may well have you covered.

I've compiled a list of all the Unicode super and subscript characters I could identify in this gist. Some of the more common/useful ones are:

• ° SUPERSCRIPT ZERO (U+2070)
• ¹ SUPERSCRIPT ONE (U+00B9)
• ² SUPERSCRIPT TWO (U+00B2)
• ³ SUPERSCRIPT THREE (U+00B3)
• n SUPERSCRIPT LATIN SMALL LETTER N (U+207F)

People also often reach for <sup> and <sub> tags in an attempt to render specific symbols like these:

• ™ TRADE MARK SIGN (U+2122)
• ® REGISTERED SIGN (U+00AE)
• ? SERVICE MARK (U+2120)

Assuming your editor supports Unicode, you can copy and paste the characters above directly into your document.

Alternatively, you could use the hex values above in an HTML character escape. Eg, ² instead of ². This works with GitHub (and should work anywhere else your Markdown is rendered to HTML) but is less readable when presented as raw text/Markdown.

Images

If your requirements are especially unusual, you can always just inline an image. The GitHub supported syntax is:

![Alt text goes here, if you'd like](path/to/image.png) 

You can use a full path (eg. starting with https:// or http://) but it's often easier to use a relative path, which will load the image from the repo, relative to the Markdown document.

If you happen to know LaTeX (or want to learn it) you could do just about any text manipulation imaginable and render it to an image. Sites like Quicklatex make this quite easy.

you should change cr_date(str) to datetime object then you 'll change the date to the specific format:

cr_date = '2013-10-31 18:23:29.000227'
cr_date = datetime.datetime.strptime(cr_date, '%Y-%m-%d %H:%M:%S.%f')
cr_date = cr_date.strftime("%m/%d/%Y")

If you want to remove the namespace you may also want to remove the version, to save you searching I've added that functionality so the below code will do both.

I've also wrapped it in a generic method as I'm creating very large xml files which are too large to serialize in memory so I've broken my output file down and serialize it in smaller "chunks":

    public static string XmlSerialize<T>(T entity) where T : class
    {
        // removes version
        XmlWriterSettings settings = new XmlWriterSettings();
        settings.OmitXmlDeclaration = true;

        XmlSerializer xsSubmit = new XmlSerializer(typeof(T));
        using (StringWriter sw = new StringWriter())
        using (XmlWriter writer = XmlWriter.Create(sw, settings))
        {
            // removes namespace
            var xmlns = new XmlSerializerNamespaces();
            xmlns.Add(string.Empty, string.Empty);

            xsSubmit.Serialize(writer, entity, xmlns);
            return sw.ToString(); // Your XML
        }
    }

To convert int32 to string in mongo without creating an array just add "" to your number :-)

db.foo.find( { 'mynum' : { $type : 16 } } ).forEach( function (x) {   
  x.mynum = x.mynum + ""; // convert int32 to string
  db.foo.save(x);
});

According to MSDN

http://msdn.microsoft.com/ru-ru/library/system.data.sqlclient.sqlcommand.executenonquery(v=vs.110).aspx

result is the number of lines affected, and since your query is select no lines are affected (i.e. inserted, deleted or updated) anyhow.

If you want to return a single row of the query, use ExecuteScalar() instead of ExecuteNonQuery():

  int result = (int) (command.ExecuteScalar());

However, if you expect many rows to be returned, ExecuteReader() is the only option:

  using (SqlDataReader reader = command.ExecuteReader()) {
    while (reader.Read()) {
      int result = reader.GetInt32(0);

      ...
    }
  }

Consider using this

WHERE x REGEXP '(^|,)(3)(,|$)'

This will match exactly 3 when x is in:

• 3
• 3,12,13
• 12,13,3
• 12,3,13

Other examples:

WHERE x REGEXP '(^|,)(3|13)(,|$)'

This will match on 3 or 13

If you want to clean up the whole form, you can use such approach. This is your model into controller:

    $scope.registrationForm = {
    'firstName'     : '',
    'lastName'      : ''
};

Your HTML:

<form class="form-horizontal" name="registrForm" role="form">
   <input type="text" class="form-control"
                       name="firstName"
                       id="firstName"
                       ng-model="registrationForm.firstName"
                       placeholder="First name"
                       required> First name
   <input type="text" class="form-control"
                       name="lastName"
                       id="lastName"
                       ng-model="registrationForm.lastName"
                       placeholder="Last name"
                       required> Last name
</form>

Then, you should clone/save your clear state by:

$scope.originForm = angular.copy($scope.registrationForm);

Your reset function will be:

$scope.resetForm = function(){
    $scope.registrationForm = angular.copy($scope.originForm); // Assign clear state to modified form 
    $scope.registrForm.$setPristine(); // this line will update status of your form, but will not clean your data, where `registrForm` - name of form.
};

In such way you are able to clean up the whole your form

First of all: I'm the author of the The Single Page Interface Manifesto cited by raganwald

As raganwald has explained very well, the most important aspect of the Single Page Interface (SPI) approach used in FaceBook and Twitter is the use of hash # in URLs

The character ! is added only for Google purposes, this notation is a Google "standard" for crawling web sites intensive on AJAX (in the extreme Single Page Interface web sites). When Google's crawler finds an URL with #! it knows that an alternative conventional URL exists providing the same page "state" but in this case on load time.

In spite of #! combination is very interesting for SEO, is only supported by Google (as far I know), with some JavaScript tricks you can build SPI web sites SEO compatible for any web crawler (Yahoo, Bing...).

The SPI Manifesto and demos do not use Google's format of ! in hashes, this notation could be easily added and SPI crawling could be even easier (UPDATE: now ! notation is used and remains compatible with other search engines).

Take a look to this tutorial, is an example of a simple ItsNat SPI site but you can pick some ideas for other frameworks, this example is SEO compatible for any web crawler.

The hard problem is to generate any (or selected) "AJAX page state" as plain HTML for SEO, in ItsNat is very easy and automatic, the same site is in the same time SPI or page based for SEO (or when JavaScript is disabled for accessibility). With other web frameworks you can ever follow the double site approach, one site is SPI based and another page based for SEO, for instance Twitter uses this "double site" technique.

I prefer to use the ngModel and ngChange directives when dealing with checkboxes. ngModel allows you to bind the checked/unchecked state of the checkbox to a property on the entity:

<input type="checkbox" ng-model="entity.isChecked">

Whenever the user checks or unchecks the checkbox the entity.isChecked value will change too.

If this is all you need then you don't even need the ngClick or ngChange directives. Since you have the "Check All" checkbox, you obviously need to do more than just set the value of the property when someone checks a checkbox.

When using ngModel with a checkbox, it's best to use ngChange rather than ngClick for handling checked and unchecked events. ngChange is made for just this kind of scenario. It makes use of the ngModelController for data-binding (it adds a listener to the ngModelController's $viewChangeListeners array. The listeners in this array get called after the model value has been set, avoiding this problem).

<input type="checkbox" ng-model="entity.isChecked" ng-change="selectEntity()">

... and in the controller ...

var model = {};
$scope.model = model;

// This property is bound to the checkbox in the table header
model.allItemsSelected = false;

// Fired when an entity in the table is checked
$scope.selectEntity = function () {
    // If any entity is not checked, then uncheck the "allItemsSelected" checkbox
    for (var i = 0; i < model.entities.length; i++) {
        if (!model.entities[i].isChecked) {
            model.allItemsSelected = false;
            return;
        }
    }

    // ... otherwise ensure that the "allItemsSelected" checkbox is checked
    model.allItemsSelected = true;
};

Similarly, the "Check All" checkbox in the header:

<th>
    <input type="checkbox" ng-model="model.allItemsSelected" ng-change="selectAll()">
</th>

... and ...

// Fired when the checkbox in the table header is checked
$scope.selectAll = function () {
    // Loop through all the entities and set their isChecked property
    for (var i = 0; i < model.entities.length; i++) {
        model.entities[i].isChecked = model.allItemsSelected;
    }
};

CSS

What is the best way to... add a CSS class to the <tr> containing the entity to reflect its selected state?

If you use the ngModel approach for the data-binding, all you need to do is add the ngClass directive to the <tr> element to dynamically add or remove the class whenever the entity property changes:

<tr ng-repeat="entity in model.entities" ng-class="{selected: entity.isChecked}">

See the full Plunker here.

in my exchange the cmd-let you presented did not work, the answer was null, so I had to make a little correction and worked fine for me:

@(get-transportservice | get-messagetrackinglog -Resultsize unlimited -Start "MM/DD/AAAA HH:MM" -End "MM/DD/AAAA HH:MM" -recipients "[email protected]" | where {$_.Event
ID -eq "DELIVER"}).count

The trick here is that Controls is not a List<> or IEnumerable but a ControlCollection.

I recommend using an extension of Control that will return something more..queriyable ;)

public static IEnumerable<Control> All(this ControlCollection controls)
    {
        foreach (Control control in controls)
        {
            foreach (Control grandChild in control.Controls.All())
                yield return grandChild;

            yield return control;
        }
    }

Then you can do :

foreach(var textbox in this.Controls.All().OfType<TextBox>)
{
    // Apply logic to the textbox here
}

//Filter out array elements with keys shorter than 4 characters // By using Anonymous function with Closure...

function comparison($min)
{
   return function($item) use ($min) { 
      return strlen($item) >= $min;   
   }; 
}

$input = array(
  0      => "val 0",
  "one"  => "val one",
  "two"  => "val two",
  "three"=> "val three",
  "four" => "val four",  
  "five" => "val five",    
  "6"    => "val 6"    
);

$output = array_filter(array_keys($input), comparison(4));

print_r($output);

Procedure + temporary table:

DELIMITER $$

CREATE DEFINER=`root`@`localhost` PROCEDURE `days`(IN dateStart DATE, IN dateEnd DATE)
BEGIN

    CREATE TEMPORARY TABLE IF NOT EXISTS date_range (day DATE);

    WHILE dateStart <= dateEnd DO
      INSERT INTO date_range VALUES (dateStart);
      SET dateStart = DATE_ADD(dateStart, INTERVAL 1 DAY);
    END WHILE;

    SELECT * FROM date_range;
    DROP TEMPORARY TABLE IF EXISTS date_range;

END

Just in case if you are using Angular.js in your project (as I am) and have a ng-model set for your <textarea>, setting the default just inside like:

<textarea ng-model='foo'>Some default value</textarea>

...will not work!

You need to set the default value to the textarea's ng-model in the respective controller or use ng-init.

Example 1 (using ng-init):

var myApp = angular.module('myApp',[]);_x000D_
_x000D_
myApp.controller('MyCtrl', [ '$scope', function($scope){_x000D_
  // your controller implementation here_x000D_
}]);

      <textarea ng-init='foo="Some default value"' ng-model='foo'></textarea>_x000D_
    </div>_x000D_
  </body>_x000D_
</html>

Example 2 (without using ng-init):

var myApp = angular.module('myApp',[]);_x000D_
_x000D_
myApp.controller('MyCtrl', [ '$scope', function($scope){_x000D_
  $scope.foo = 'Some default value';_x000D_
}]);

</html>

There can be a problem with "\00a0" in pseudo-elements because it takes the text-decoration of its defining element, so that, for example, if the defining element is underlined, then the white space of the pseudo-element is also underlined.

The easiest way to deal with this is to define the opacity of the pseudo-element to be zero, eg:

element:before{
  content: "_";
  opacity: 0;
}

Removing the project imported with first method, and then re-importing it with the second method solved the problem for me.

Simply add a class name to the beginning of the funciton and the 2nd and 3rd arguments are optional and the magic is done for you!

function getElementsByClass(searchClass, node, tag) {

  var classElements = new Array();

  if (node == null)

    node = document;

  if (tag == null)

    tag = '*';

  var els = node.getElementsByTagName(tag);

  var elsLen = els.length;

  var pattern = new RegExp('(^|\\\\s)' + searchClass + '(\\\\s|$)');

  for (i = 0, j = 0; i < elsLen; i++) {

    if (pattern.test(els[i].className)) {

      classElements[j] = els[i];

      j++;

    }

  }

  return classElements;

}

You can also just do this in all the activities that you dont want to transition from:

@Override
public void onPause() {
    super.onPause();
    overridePendingTransition(0, 0);
}

I like this approach because you do not have to mess with the style of your activity.

Many of the above methods have been deprecated. It is now recommended to use the constructor found here

function clickAnchorTag() {
    var event = document.createEvent('MouseEvent');
    event = new CustomEvent('click');
    var a = document.getElementById('nameOfID');
    a.dispatchEvent(event);
}

This will cause the anchor tag to be clicked, but it wont show if pop-up blockers are active so the user will need to allow pop-ups.

If you have some image files, just upload them to a public folder on your Google Drive, copy its folder ID from the address bar (e.g. 0B0Gi4v5omoZUVXhCT2kta1l0ZG8) and paste it into a form at GDrives, then choose your own alias (e.g. myimgs) and voila! You can access the images one by one using e.g. http://gdriv.es/myimgs/myimage.jpg.

If you want to embed a whole folder on your website (in a frame), you can use one of the following URLs, replacing [folderID] with your own ID:

• http://gdriv.es/myimgs/
• https://docs.google.com/folder/d/[folderID]/preview?rm=minimal
• https://drive.google.com/folderview?id=[folderID]

If you prefer to get the file list in XML or JSON, you can use YQL.

Note: You can use Google+ Photos to host ans embed your images as well.

From verify documentation:

If a certificate is found which is its own issuer it is assumed to be the root CA.

In other words, root CA needs to self signed for verify to work. This is why your second command didn't work. Try this instead:

openssl verify -CAfile RootCert.pem -untrusted Intermediate.pem UserCert.pem

It will verify your entire chain in a single command.

Private Sub main()

\n didn't work for me. the \n appear in the bodytext of the email I was sending.. this is how I resolved it.

str_pad($input, 990); //so that the spaces will pad out to the 990 cut off.

Did you recently switch from MySQL and are now longing for the logical equivalents of its more simple commands in Oracle? Because that is the case for me and I had the very same question. This code will give you a quick and dirty print which I think is what you're looking for:

Variable n number
begin
    :n := 1;
end;
print n

The middle section is a PL/SQL bit that binds the variable. The output from print n is in column form, and will not just give the value of n, I'm afraid. When I ran it in Toad 11 it returned like this

        n
---------
        1

I hope that helps

make a function in ~/.config/fish/functions called mkalias.fish and put this in

function mkalias --argument key value
  echo alias $key=$value
  alias $key=$value
  funcsave $key
end

and this will create aliases automatically.

Don't know if anyone is still looking here, but you can do this by going to Window menu > Preferences, then open the General list, choose keys. Scroll down the list of keys until you see "Shift Left". Click that. Below that you'll see some boxes, one of which lets you bind a key. It won't accept Shift-Tab, so I bound it to Shift-`. Apply-and-close and you're all set.

I know that this is an old question that has been well answered, but for my own amusement I wrote the following reverse function and thought I would share it in case it was useful for anyone else. It handles both surrogate pairs and combining marks:

function StringReverse (str)
{
  var charArray = [];
  for (var i = 0; i < str.length; i++)
    {
      if (i+1 < str.length)
        {
          var value = str.charCodeAt(i);
          var nextValue = str.charCodeAt(i+1);
          if (   (   value >= 0xD800 && value <= 0xDBFF
                  && (nextValue & 0xFC00) == 0xDC00) // Surrogate pair)
              || (nextValue >= 0x0300 && nextValue <= 0x036F)) // Combining marks
            {
              charArray.unshift(str.substring(i, i+2));
              i++; // Skip the other half
              continue;
            }
        }

      // Otherwise we just have a rogue surrogate marker or a plain old character.
      charArray.unshift(str[i]);
    }

  return charArray.join('');
}

All props to Mathias, Punycode, and various other references for schooling me on the complexities of character encoding in JavaScript.

Here is one method:

<bean id="stage1" class="Stageclass"/>
<bean id="stage2" class="Stageclass"/>

The Java runtime you try to execute your program with is an earlier version than Java 7 which was the target you compile your program for.

For Ubuntu use

apt-get install openjdk-7-jdk

to get Java 7 as default. You may have to uninstall openjdk-6 first.

I had a very similar problem where for the form action, I had something like:

<form action="http://www.example.com/?q=content/something" method="GET">
   <input type="submit" value="Go away..." />&nbsp;
</form>

The button would get the user to the site, but the query info disappeared so the user landed on the home page rather than the desired content page. The solution in my case was to find out how to code the URL without the query that would get the user to the desired page. In this case my target was a Drupal site, so as it turned out /content/something also worked. I also could have used a node number (i.e. /node/123).

docker inspect <container id> | grep -i "ipaddress"

One simple way can be the use of assign() function that is pre-defined in vector class.

e.g.

array[5]={1,2,3,4,5};

vector<int> v;
v.assign(array, array+5); // 5 is size of array.

Angular 2 with Webpack (without CLI setup)

1- The tutorial by the Angular2 team

The Angular2 team published a tutorial for using Webpack

I created and placed the files from the tutorial in a small GitHub seed project. So you can quickly try the workflow.

Instructions:

• npm install

• npm start. For development. This will create a virtual "dist" folder that will be livereloaded at your localhost address.

• npm run build. For production. "This will create a physical "dist" folder version than can be sent to a webserver. The dist folder is 7.8MB but only 234KB is actually required to load the page in a web browser.
  
  

2 - A Webkit starter kit

This Webpack Starter Kit offers some more testing features than the above tutorial and seem quite popular.

In bash:

#!/bin/bash
echo before comment
: <<'END'
bla bla
blurfl
END
echo after comment

The ' and ' around the END delimiter are important, otherwise things inside the block like for example $(command) will be parsed and executed.

For an explanation, see this and this question.

For x and y axes:

     options : {
      scales: {
        yAxes: [{
          scaleLabel: {
            display: true,
            labelString: 'probability'
          }
        }],
        xAxes: [{
          scaleLabel: {
            display: true,
            labelString: 'hola'
          }
        }],
      }
    }

You could add dataformatstring="{0:M-dd-yyyy}" attribute to the bound field, like this:

<asp:BoundField DataField="Date" HeaderText="Date" DataFormatString="{0:dd-M-yyyy}" />

source: cant format datetime using dataformatstring

Lets say you saved your software onto your desktop.
if you want to remove an entire folder like an uninstaller program you could use this.

cd C:\Users\User\Detsktop\
rd /s /q SOFTWARE

this will delete the entire folder called software and all of its files and subfolders

Make Sure You Delete The Correct Folder Cause This Does Not Have A Yes / No Option

No, the HTML5 range input only accepts one input. I would recommend you to use something like the jQuery UI range slider for that task.

stripslashes(htmlspecialchars(JSON_DATA))

Instead of

<button ng-click="removeTask({{task.id}})">remove</button>

do this:

<button ng-click="removeTask(task.id)">remove</button>

Please see this fiddle:

http://jsfiddle.net/JSWorld/Hp4W7/34/

Use the java.lang.Math class, and specifically for absolute value and square root:, the abs() and sqrt() methods.

I have used phpMyFAQ and found it to be very good.

The answer to the question specifically asked is no. But have you been looking at mocking frameworks? I use MOQ but there's millions of them out there and they allow you to implement/stub (partially or fully) interfaces in-line. Eg.

public void ThisWillWork()
{
    var source = new DummySource[0];
    var mock = new Mock<DummyInterface>();

    mock.SetupProperty(m => m.A, source.Select(s => s.A));
    mock.SetupProperty(m => m.B, source.Select(s => s.C + "_" + s.D));

    DoSomethingWithDummyInterface(mock.Object);
}

(Kotlin) In the activity hosting the fragment(s):

    override fun onOptionsItemSelected(item: MenuItem): Boolean {
    when (item.itemId) {
        android.R.id.home -> {
            onBackPressed()
            return true
        }
    }
    return super.onOptionsItemSelected(item)
}

I have found that when I add fragments to a project, they show the action bar home button by default, to remove/disable it put this in onViewCreated() (use true to enable it if it is not showing):

val actionBar = this.requireActivity().actionBar
    actionBar?.setDisplayHomeAsUpEnabled(false)

You can use bash. Note for very large files in terms of GB, use awk/wc. However it should still be manageable in performance for files with a few MB.

declare -i count=0
while read
do
    ((count++))
done < file    
echo "line count: $count"

As of April 2018, Chrome (along with several other major browsers) now require the muted attribute too.

Therefore, you should use

<video width="320" height="240" autoplay loop muted>
  <source src="movie.mp4" type="video/mp4" />
</video>

<img src="images/delete.png" onclick="return confirm_delete('Are you sure?')"> 



<script type="text/javascript">
function confirm_delete(question) {

  if(confirm(question)){

     alert("Action to delete");

  }else{
    return false;  
  }

}
</script>

Similar simple solution that enables multiple spinners is to put the AdapterView in a collection - in the Activities superclass - on first execution of onItemSelected(...) Then check to see if the AdapterView is in the collection before executing it. This enables one set of methods in the superclass and supports multiple AdapterViews and therefor multiple spinners.

Superclass ...

private Collection<AdapterView> AdapterViewCollection = new ArrayList<AdapterView>();

   protected boolean firstTimeThrough(AdapterView parent) {
    boolean firstTimeThrough = ! AdapterViewCollection.contains(parent);
    if (firstTimeThrough) {
       AdapterViewCollection.add(parent);
     }
    return firstTimeThrough;
   }

Subclass ...

public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
      if (! firstTimeThrough(parent)) {
        String value = safeString(parent.getItemAtPosition(pos).toString());
        String extraMessage = EXTRA_MESSAGE;
        Intent sharedPreferencesDisplayIntent = new         Intent(SharedPreferencesSelectionActivity.this,SharedPreferencesDisplayActivity.class);
    sharedPreferencesDisplayIntent.putExtra(extraMessage,value);
    startActivity(sharedPreferencesDisplayIntent);
  }
  // don't execute the above code if its the first time through
  // do to onItemSelected being called during view initialization.

}

$array = explode("\n", $text);
for($i=0; $i < count($array); $i++)
{
    echo $line;
    if($i < count($array)-1)
    {
         echo '<br />';
    }
}

setInterval returns an id that you can use to cancel the interval with clearInterval()

From SQL Server point of view:

Clustering will give you an active - passive configuration. Meaning in a 2 node cluster, one of them will be the active (serving) and the other one will be passive (waiting to take over when the active node fails). It's a high availability from hardware point of view.

You can have an active-active cluster, but it will require multiple instances of SQL Server running on each node. (i.e. Instance 1 on Node A failing over to Instance 2 on Node B, and instance 1 on Node B failing over to instance 2 on Node A).

Load balancing (at least from SQL Server point of view) does not exists (at least in the same sense of web server load balancing). You can't balance load that way. However, you can split your application to run on some database on server 1 and also run on some database on server 2, etc. This is the primary mean of "load balancing" in SQL world.

HTML

<form id="contactform"></form>

JavaScript

 var $contactform = $('#contactform')
    $($contactform).find("input[type=text] , textarea ").each(function(){
                $(this).val('');            
    });

Simple and short function to clear all fields

Problem is, you're trying to upcast to a richer object. You simply need to add the items to a new list:

if (myObject is IEnumerable)
{
   List<object> list = new List<object>();
   var enumerator = ((IEnumerable) myObject).GetEnumerator();
   while (enumerator.MoveNext())
   {
      list.Add(enumerator.Current);
   }
}

As said, the browser doesn't let the server know when it closes.

Still, there are some ways to achieve close to this behavior. You can put a small AJAX script in place that updates the server regularly that the browser is open. You should pair this with something that fires on actions made by the user, so you can time out an idle session as well as one that has closed out.

Update for Swift 3:

Update Info.plist with the following info:

View controller-based status bar appearance: NO

Then, in a ViewController or elsewhere:

UIApplication.shared.isStatusBarHidden = true

It's no join since the relationship will only be evaluated when needed. A join (in a SQL database) on the other hand will resolve relationships and return them as if they were a single table (you "join two tables into one").

You can read more about DBRef here: http://docs.mongodb.org/manual/applications/database-references/

There are two possible solutions for resolving references. One is to do it manually, as you have almost described. Just save a document's _id in another document's other_id, then write your own function to resolve the relationship. The other solution is to use DBRefs as described on the manual page above, which will make MongoDB resolve the relationship client-side on demand. Which solution you choose does not matter so much because both methods will resolve the relationship client-side (note that a SQL database resolves joins on the server-side).

SimpleDateFormat is great, just note that HH is different from hh when working with hours. HH will return 24 hour based hours and hh will return 12 hour based hours.

For example, the following will return 12 hour time:

SimpleDateFormat sdf = new SimpleDateFormat("hh:mm aa");

While this will return 24 hour time:

SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");

If you installed the package with the Ubuntu package manager (apt, synaptic, dpkg or similar), you can get information about the installed package with

dpkg -L <package_name>

You should run your entire script as superuser. If you want to run some command as non-superuser, use "-u" option of sudo:

#!/bin/bash

sudo -u username command1
command2
sudo -u username command3
command4

When running as root, sudo doesn't ask for a password.

Yes, very weird situation for oracle.

if you specify 2000 ids inside the IN clause, it will fail. this fails:

select ... 
where id in (1,2,....2000) 

but if you simply put the 2000 ids in another table (temp table for example), it will works below query:

select ... 
where id in (select userId 
             from temptable_with_2000_ids ) 

what you can do, actually could split the records into a lot of 1000 records and execute them group by group.

This is an old question, nevertheless the answers did not satisfy me regarding to performance and optimization.

Here my optimized C# variant (distance in km, without variables and redundant calculations, very close to mathematical expression of Haversine Formular https://en.wikipedia.org/wiki/Haversine_formula).

Inspired by: https://rosettacode.org/wiki/Haversine_formula#C.23

public static class Haversine
{
    public static double Calculate(double lat1, double lon1, double lat2, double lon2)
    {
        double rad(double angle) => angle * 0.017453292519943295769236907684886127d; // = angle * Math.Pi / 180.0d
        double havf(double diff) => Math.Pow(Math.Sin(rad(diff) / 2d), 2); // = sin²(diff / 2)
        return 12745.6 * Math.Asin(Math.Sqrt(havf(lat2 - lat1) + Math.Cos(rad(lat1)) * Math.Cos(rad(lat2)) * havf(lon2 - lon1))); // earth radius 6.372,8?km x 2 = 12745.6
    }
}

You cannot use the VB line-continuation character inside of a string.

SqlQueryString = "Insert into Employee values(" & txtEmployeeNo.Value & _
"','" & txtContractStartDate.Value &  _
"','" & txtSeatNo.Value & _
"','" & txtFloor.Value & "','" & txtLeaves.Value & "')"

New Way (Recommended):

Please take a look at this answer.

Old Way:

Supposing you're writing a program called myprog :

Put all your files in a directory like this

myproject/go/src/myprog/xxx.go

Then add myproject/go to GOPATH

And run

go install myprog

This way you'll be able to add other packages and programs in myproject/go/src if you want.

Reference : http://golang.org/doc/code.html

(this doc is always missed by newcomers, and often ill-understood at first. It should receive the greatest attention of the Go team IMO)

You can look for regular expression

Regex.IsMatch(str, @"^[a-zA-Z]+$");

One thing to note:
I have had issues with websockets and corporate firewalls. (Using HTTPS helps but not always.)

See https://github.com/LearnBoost/socket.io/wiki/Socket.IO-and-firewall-software https://github.com/sockjs/sockjs-client/issues/94

I assume there aren't as many issues with Server-Sent Events. But I don't know.

That said, WebSockets are tons of fun. I have a little web game that uses websockets (via Socket.IO) (http://minibman.com)

Try this...

SELECT
    AlarmEventTransactionTableTable.TxnID,
    CASE
        WHEN DeviceID IN('7', '10', '62', '58', '60',
                 '46', '48', '50', '137', '139',
                 '142', '143', '164') THEN '01'
        WHEN DeviceID IN('8', '9', '63', '59', '61',
                 '47', '49', '51', '138', '140',
                 '141', '144', '165') THEN '02'
        ELSE 'NA' END AS clocking,
    AlarmEventTransactionTable.DateTimeOfTxn
 FROM
    multiMAXTxn.dbo.AlarmEventTransactionTable

Just remove highlighted string

SELECT AlarmEventTransactionTableTable.TxnID, CASE AlarmEventTransactions.DeviceID WHEN DeviceID IN('7', '10', '62', '58', '60', ...)

*

explained with respect to, linux/unix based systems, though it's a basic concept for all other computing systems.

*

Linkers and Loaders from LinuxJournal explains this concept with clarity. It also explains how the classic name a.out came. (assembler output)

A quick summary,

c program --> [compiler] --> objectFile --> [linker] --> executable file (say, a.out)

we got the executable, now give this file to your friend or to your customer who is in need of this software :)

when they run this software, say by typing it in command line ./a.out

execute in command line ./a.out --> [Loader] --> [execve] --> program is loaded in memory

Once the program is loaded into the memory, control is transferred to this program by making the PC (program counter) pointing to the first instruction of a.out

Why reinvent the wheel, use the Threading and the Timer class.

    protected void Application_Start()
    {
        Thread thread = new Thread(new ThreadStart(ThreadFunc));
        thread.IsBackground = true;
        thread.Name = "ThreadFunc";
        thread.Start();
    }

    protected void ThreadFunc()
    {
        System.Timers.Timer t = new System.Timers.Timer();
        t.Elapsed += new System.Timers.ElapsedEventHandler(TimerWorker);
        t.Interval = 10000;
        t.Enabled = true;
        t.AutoReset = true;
        t.Start();
    }

    protected void TimerWorker(object sender, System.Timers.ElapsedEventArgs e)
    {
        //work args
    }

If you are only comparing objects of the same type or further down the inheritance chain, why not specify the parameter as your base type, rather than object ?

Also do null checks on the parameter as well.

Furthermore I'd make use of 'var' just to make the code more readable (if its c#3 code)

Also, if the object has reference types as properties then you are just calling ToString() on them which doesn't really compare values. If ToString isn't overwridden then its just going to return the type name as a string which could return false-positives.

In templates, you can separate filter arguments by colons.

{{ yourExpression | yourFilter: arg1:arg2:... }}

From Javascript, you call it as

$filter('yourFilter')(yourExpression, arg1, arg2, ...)

There is actually an example hidden in the orderBy filter docs.

Example:

Let's say you make a filter that can replace things with regular expressions:

myApp.filter("regexReplace", function() { // register new filter

  return function(input, searchRegex, replaceRegex) { // filter arguments

    return input.replace(RegExp(searchRegex), replaceRegex); // implementation

  };
});

Invocation in a template to censor out all digits:

<p>{{ myText | regexReplace: '[0-9]':'X' }}</p>

A priority queue is an abstract data type that captures the idea of a container whose elements have "priorities" attached to them. An element of highest priority always appears at the front of the queue. If that element is removed, the next highest priority element advances to the front.

The C++ standard library defines a class template priority_queue, with the following operations:

push: Insert an element into the prioity queue.

top: Return (without removing it) a highest priority element from the priority queue.

pop: Remove a highest priority element from the priority queue.

size: Return the number of elements in the priority queue.

empty: Return true or false according to whether the priority queue is empty or not.

The following code snippet shows how to construct two priority queues, one that can contain integers and another one that can contain character strings:

#include <queue>

priority_queue<int> q1;
priority_queue<string> q2;

The following is an example of priority queue usage:

#include <string>
#include <queue>
#include <iostream>

using namespace std;  // This is to make available the names of things defined in the standard library.

int main()
{
    piority_queue<string> pq; // Creates a priority queue pq to store strings, and initializes the queue to be empty.

    pq.push("the quick");
    pq.push("fox");
    pq.push("jumped over");
    pq.push("the lazy dog");

    // The strings are ordered inside the priority queue in lexicographic (dictionary) order:
    // "fox", "jumped over", "the lazy dog", "the quick"
    //  The lowest priority string is "fox", and the highest priority string is "the quick"

    while (!pq.empty()) {
       cout << pq.top() << endl;  // Print highest priority string
       pq.pop();                    // Remmove highest priority string
    }

    return 0;
}

The output of this program is:

the quick
the lazy dog
jumped over
fox

Since a queue follows a priority discipline, the strings are printed from highest to lowest priority.

Sometimes one needs to create a priority queue to contain user defined objects. In this case, the priority queue needs to know the comparison criterion used to determine which objects have the highest priority. This is done by means of a function object belonging to a class that overloads the operator (). The overloaded () acts as < for the purpose of determining priorities. For example, suppose we want to create a priority queue to store Time objects. A Time object has three fields: hours, minutes, seconds:

struct Time {
    int h; 
    int m; 
    int s;
};

class CompareTime {
    public:
    bool operator()(Time& t1, Time& t2) // Returns true if t1 is earlier than t2
    {
       if (t1.h < t2.h) return true;
       if (t1.h == t2.h && t1.m < t2.m) return true;
       if (t1.h == t2.h && t1.m == t2.m && t1.s < t2.s) return true;
       return false;
    }
}

A priority queue to store times according the the above comparison criterion would be defined as follows:

priority_queue<Time, vector<Time>, CompareTime> pq;

Here is a complete program:

#include <iostream>
#include <queue>
#include <iomanip>

using namespace std;

struct Time {
    int h; // >= 0
    int m; // 0-59
    int s; // 0-59
};

class CompareTime {
public:
    bool operator()(Time& t1, Time& t2)
    {
       if (t1.h < t2.h) return true;
       if (t1.h == t2.h && t1.m < t2.m) return true;
       if (t1.h == t2.h && t1.m == t2.m && t1.s < t2.s) return true;
       return false;
    }
};

int main()
{
    priority_queue<Time, vector<Time>, CompareTime> pq;

    // Array of 4 time objects:

    Time t[4] = { {3, 2, 40}, {3, 2, 26}, {5, 16, 13}, {5, 14, 20}};

    for (int i = 0; i < 4; ++i)
       pq.push(t[i]);

    while (! pq.empty()) {
       Time t2 = pq.top();
       cout << setw(3) << t2.h << " " << setw(3) << t2.m << " " <<
       setw(3) << t2.s << endl;
       pq.pop();
    }

    return 0;
}

The program prints the times from latest to earliest:

5  16  13
5  14  20
3   2  40
3   2  26

If we wanted earliest times to have the highest priority, we would redefine CompareTime like this:

class CompareTime {
public:
    bool operator()(Time& t1, Time& t2) // t2 has highest prio than t1 if t2 is earlier than t1
    {
       if (t2.h < t1.h) return true;
       if (t2.h == t1.h && t2.m < t1.m) return true;
       if (t2.h == t1.h && t2.m == t1.m && t2.s < t1.s) return true;
       return false;
    }
};
