Suppose the pattern you want is abc+d. You want to match the second occurrence of this pattern in a string.

You would construct the following regex:

abc+d.*?(abc+d)

This would match strings of the form: <your-pattern>...<your-pattern>. Since we're using the reluctant qualifier *? we're safe that there cannot be another match of between the two. Using matcher groups which pretty much all regex implementations provide you would then retrieve the string in the bracketed group which is what you want.

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

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

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

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

        return result;
    }

I recommend using pure JavaScript in this case, also there is no insert method in JavaScript, but we have a method which is a built-in Array method which does the job for you, it's called splice...

Let's see what's splice()...

The splice() method changes the contents of an array by removing existing elements and/or adding new elements.

OK, imagine we have this array below:

const arr = [1, 2, 3, 4, 5];

We can remove 3 like this:

arr.splice(arr.indexOf(3), 1);

It will return 3, but if we check the arr now, we have:

[1, 2, 4, 5]

So far, so good, but how we can add a new element to array using splice? Let's put back 3 in the arr...

arr.splice(2, 0, 3);

Let's see what we have done...

We use splice again, but this time for the second argument, we pass 0, means we want to delete no item, but at the same time, we add third argument which is 3 that will be added at second index...

You should be aware, that we can delete and add at the same time, for example now we can do:

arr.splice(2, 2, 3);

Which will delete 2 items at index 2, then add 3 at index 2 and result will be:

[1, 2, 3, 5];

This is showing how each item in splice work:

array.splice(start, deleteCount, item1, item2, item3 ...)

I found an a bit different solution of my problem regarding this context. Thought worth sharing.

Most of the example create readStreams from file. But in my case readStream has to be created from JSON string coming from a message pool.

var jsonStream = through2.obj(function(chunk, encoding, callback) {
                    this.push(JSON.stringify(chunk, null, 4) + '\n');
                    callback();
                });
// message.value --> value/text to write in write.txt 
jsonStream.write(JSON.parse(message.value));
var writeStream = sftp.createWriteStream("/path/to/write/write.txt");

//"close" event didn't work for me!
writeStream.on( 'close', function () {
    console.log( "- done!" );
    sftp.end();
    }
);

//"finish" event didn't work for me either!
writeStream.on( 'close', function () {
    console.log( "- done!"
        sftp.end();
        }
);

// finally this worked for me!
jsonStream.on('data', function(data) {
    var toString = Object.prototype.toString.call(data);
    console.log('type of data:', toString);
    console.log( "- file transferred" );
});

jsonStream.pipe( writeStream );

Good cocoa function:

-(BOOL) NSStringIsValidEmail:(NSString *)checkString
{
   BOOL stricterFilter = NO; // Discussion http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/
   NSString *stricterFilterString = @"^[A-Z0-9a-z\\._%+-]+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2,4}$";
   NSString *laxString = @"^.+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2}[A-Za-z]*$";
   NSString *emailRegex = stricterFilter ? stricterFilterString : laxString;
   NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
   return [emailTest evaluateWithObject:checkString];
}

Discussion on Lax vs. Strict - http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/

And because categories are just better, you could also add an interface:

@interface NSString (emailValidation) 
  - (BOOL)isValidEmail;
@end

Implement

@implementation NSString (emailValidation)
-(BOOL)isValidEmail
{
  BOOL stricterFilter = NO; // Discussion http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/
  NSString *stricterFilterString = @"^[A-Z0-9a-z\\._%+-]+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2,4}$";
  NSString *laxString = @"^.+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2}[A-Za-z]*$";
  NSString *emailRegex = stricterFilter ? stricterFilterString : laxString;
  NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
  return [emailTest evaluateWithObject:self];
}
@end

And then utilize:

if([@"[email protected]" isValidEmail]) { /* True */ }
if([@"InvalidEmail@notreallyemailbecausenosuffix" isValidEmail]) { /* False */ }

Check if there is any conflict in your IIS authentication. i.e. you enable the anonymous authentication and ASP.NET impersonation both might cause the error also.

I believe contentOffset will give you an object containing the top-left scroll offset:

http://facebook.github.io/react-native/docs/scrollview.html#contentoffset

There is no notion of a function in the JDK as of java 6.

Guava has a Function interface though and the
Collections2.transform(Collection<E>, Function<E,E2>)
method provides the functionality you require.

Example:

// example, converts a collection of integers to their
// hexadecimal string representations
final Collection<Integer> input = Arrays.asList(10, 20, 30, 40, 50);
final Collection<String> output =
    Collections2.transform(input, new Function<Integer, String>(){

        @Override
        public String apply(final Integer input){
            return Integer.toHexString(input.intValue());
        }
    });
System.out.println(output);

Output:

[a, 14, 1e, 28, 32]

These days, with Java 8, there is actually a map function, so I'd probably write the code in a more concise way:

Collection<String> hex = input.stream()
                              .map(Integer::toHexString)
                              .collect(Collectors::toList);

Schemas logically group tables, procedures, views together. All employee-related objects in the employee schema, etc.

You can also give permissions to just one schema, so that users can only see the schema they have access to and nothing else.

If you try to set the DataGrid.CellStyle the DataContext will be the row, so if you want to change the colour based on one cell it might be easiest to do so in specific columns, especially since columns can have varying contents, like TextBlocks, ComboBoxes and CheckBoxes. Here is an example of setting all the cells light-green where the Name is John:

<DataGridTextColumn Binding="{Binding Name}">
    <DataGridTextColumn.ElementStyle>
        <Style TargetType="{x:Type TextBlock}">
            <Style.Triggers>
                <Trigger Property="Text" Value="John">
                    <Setter Property="Background" Value="LightGreen"/>
                </Trigger>
            </Style.Triggers>
        </Style>
    </DataGridTextColumn.ElementStyle>
</DataGridTextColumn>

You could also use a ValueConverter to change the colour.

public class NameToBrushConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        string input = value as string;
        switch (input)
        {
            case "John":
                return Brushes.LightGreen;
            default:
                return DependencyProperty.UnsetValue;
        }
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotSupportedException();
    }
}

Usage:

<Window.Resources>
    <local:NameToBrushConverter x:Key="NameToBrushConverter"/>
</Window.Resources>
...
<DataGridTextColumn Binding="{Binding Name}">
    <DataGridTextColumn.ElementStyle>
        <Style TargetType="{x:Type TextBlock}">
            <Setter Property="Background" Value="{Binding Name, Converter={StaticResource NameToBrushConverter}}"/>
        </Style>
    </DataGridTextColumn.ElementStyle>
</DataGridTextColumn>

Yet another option is to directly bind the Background to a property which returns the respectively coloured brush. You will have to fire property change notifications in the setters of properties on which the colour is dependent.

e.g.

public string Name
{
    get { return _name; }
    set
    {
        if (_name != value)
        {
            _name = value;
            OnPropertyChanged(nameof(Name));
            OnPropertyChanged(nameof(NameBrush));
        }
    }
}

public Brush NameBrush
{
    get
    {
        switch (Name)
        {
            case "John":
                return Brushes.LightGreen;
            default:
                break;
        }

        return Brushes.Transparent;
    }
}

I made a plugin for the simulator that does just this. You can find it at my blog.

It actually records the screen. It does not rely on another screen capture program like iShowU.

It will install icons for the default apps and change the carrier text to look like a real device.

If you're in Webdevelopper hell and need to make this work for IE6, here's a sample code I used:

<html>
<head>
<style type="text/css">
.fixme {
    position: relative;
    left: expression( ( 20 + ( ignoreMe2 = document.documentElement.scrollLeft ? document.documentElement.scrollLeft : document.body.scrollLeft ) ) + 'px' );
    background-color: #FFFFFF;
}
</style>
</head>
<body>
<table width="1500px" border="2">
    <tr>

This will work probably ONLY for IE6, so use conditional comments for the CSS.

You set an element's id by setting its corresponding property:

myPara.id = ID;

The key must be indexed to apply foreign key constraint. To do that follow the steps.

1. Open table structure. (2nd tab)
2. See the last column action where multiples action options are there. Click on Index, this will make the column indexed.
3. Open relation view and add foreign key constraint.

You will be able to assign DOCTOR_ID as foreign now.

The raw_json_encode() function above did not solve me the problem (for some reason, the callback function raised an error on my PHP 5.2.5 server).

But this other solution did actually work.

https://www.experts-exchange.com/questions/28628085/json-encode-fails-with-special-characters.html

Credits should go to Marco Gasi. I just call his function instead of calling json_encode():

function jsonRemoveUnicodeSequences( $json_struct )
{ 
    return preg_replace( "/\\\\u([a-f0-9]{4})/e", "iconv('UCS-4LE','UTF-8',pack('V', hexdec('U$1')))", json_encode( $json_struct ) );
}

Since we are in the HTML5 realm, this is my solution. The gist is that you push the files to an Array instead of leaving them in a FileList, then using XHR2, you push the files to a FormData object. Example below.

Node.prototype.replaceWith = function(node)
{
    this.parentNode.replaceChild(node, this);
};
if(window.File && window.FileList)
{
    var topicForm = document.getElementById("yourForm");
    topicForm.fileZone = document.getElementById("fileDropZoneElement");
    topicForm.fileZone.files = new Array();
    topicForm.fileZone.inputWindow = document.createElement("input");
    topicForm.fileZone.inputWindow.setAttribute("type", "file");
    topicForm.fileZone.inputWindow.setAttribute("multiple", "multiple");
    topicForm.onsubmit = function(event)
    {
        var request = new XMLHttpRequest();
        if(request.upload)
        {
            event.preventDefault();
            topicForm.ajax.value = "true";
            request.upload.onprogress = function(event)
            {
                var progress = event.loaded.toString() + " bytes transfered.";
                if(event.lengthComputable)
                progress = Math.round(event.loaded / event.total * 100).toString() + "%";
                topicForm.fileZone.innerHTML = progress.toString();
            };
            request.onload = function(event)
            {
                response = JSON.parse(request.responseText);
                // Handle the response here.
            };
            request.open(topicForm.method, topicForm.getAttribute("action"), true);
            var data = new FormData(topicForm);
            for(var i = 0, file; file = topicForm.fileZone.files[i]; i++)
                data.append("file" + i.toString(), file);
            request.send(data);
        }
    };
    topicForm.fileZone.firstChild.replaceWith(document.createTextNode("Drop files or click here."));
    var handleFiles = function(files)
    {
        for(var i = 0, file; file = files[i]; i++)
            topicForm.fileZone.files.push(file);
    };
    topicForm.fileZone.ondrop = function(event)
    {
        event.stopPropagation();
        event.preventDefault();
        handleFiles(event.dataTransfer.files);
    };
    topicForm.fileZone.inputWindow.onchange = function(event)
    {
        handleFiles(topicForm.fileZone.inputWindow.files);
    };
    topicForm.fileZone.ondragover = function(event)
    {
        event.stopPropagation();
        event.preventDefault();
    };
    topicForm.fileZone.onclick = function()
    {
        topicForm.fileZone.inputWindow.focus();
        topicForm.fileZone.inputWindow.click();
    };
}
else
    topicForm.fileZone.firstChild.replaceWith(document.createTextNode("It's time to update your browser."));

I realize you needed a solution for IE6/7 but I'm just throwing this out for anyone else.

If you can't use table-layout: fixed and you don't care about IE < 9 this works for all browsers.

td {
    overflow-x: hidden;
    overflow-y: hidden;
    white-space: nowrap;
    max-width: 30px;
}

The difference appears when the special parameters are quoted. Let me illustrate the differences:

$ set -- "arg  1" "arg  2" "arg  3"

$ for word in $*; do echo "$word"; done
arg
1
arg
2
arg
3

$ for word in $@; do echo "$word"; done
arg
1
arg
2
arg
3

$ for word in "$*"; do echo "$word"; done
arg  1 arg  2 arg  3

$ for word in "$@"; do echo "$word"; done
arg  1
arg  2
arg  3

one further example on the importance of quoting: note there are 2 spaces between "arg" and the number, but if I fail to quote $word:

$ for word in "$@"; do echo $word; done
arg 1
arg 2
arg 3

and in bash, "$@" is the "default" list to iterate over:

$ for word; do echo "$word"; done
arg  1
arg  2
arg  3

I will add a StackBlitz example and a comment to the answer from @tahiche.

The return value is a function to remove the event listener after you have added it. It is considered good practice to remove event listeners when you don't need them anymore. So you can store this return value and call it inside your ngOnDestroy method.

I admit that it might seem confusing at first, but it is actually a very useful feature. How else can you clean up after yourself?

export class MyComponent implements OnInit, OnDestroy {

  public removeEventListener: () => void;

  constructor(
    private renderer: Renderer2, 
    private elementRef: ElementRef
  ) {
  }

  public ngOnInit() {
    this.removeEventListener = this.renderer.listen(this.elementRef.nativeElement, 'click', (event) => {
      if (event.target instanceof HTMLAnchorElement) {
        // Prevent opening anchors the default way
        event.preventDefault();
        // Your custom anchor click event handler
        this.handleAnchorClick(event);
      }
    });
  }

  public ngOnDestroy() {
    this.removeEventListener();
  }
}

You can find a StackBlitz here to show how this could work for catching clicking on anchor elements.

I added a body with an image as follows:
<img src="x" onerror="alert(1)"></div>
to show that the sanitizer is doing its job.

Here in this fiddle you find the same body attached to an innerHTML without sanitizing it and it will demonstrate the issue.

I think the best solution to this problem can be found here: IIS_IUSRS and IUSR permissions in IIS8 This a good workaround but it does not work when you access the webserver over the Internet.

I am assuming that we are dealing with a JFrame? The visible portion in the content pane - you have to use jframe.getContentPane().setBackground(...);

In the manifest file Change:

    android:theme="@style/AppTheme" >
    android:theme="@style/Theme.AppCompat.NoActionBar"

Seems like the problem is with the date format.

 var d = "17-09-2013 10:08",
 dArr = d.split('-'),
 ts = new Date(dArr[1] + "-" + dArr[0] + "-" + dArr[2]).getTime(); // 1379392680000

var arrofobject = [{"id":"197","category":"Damskie"},{"id":"198","category":"M\u0119skie"}];

$.each(arrofobject, function(index, val) {
    console.log(val.category);
});

If you are being stuck on this problem. After switch the computer and not able to upload your build to App Store. Simply click manage certificate on the error page, the + plus on the bottom left corner and create a new distribution certificate. Then you'll be good to go.

I like ThomasA's answer, but wanted a more realistic context with the wave being used to separate two divs. So I created a more complete demo where the separator SVG gets positioned perfectly between the two divs.

Now I thought it would be cool to take it further. What if we could do this all in CSS without the need for the inline SVG? The point being to avoid extra markup. Here's how I did it:

Two simple <div>:

Demo Wavy divider (with CSS pseudo-elements to avoid extra markup)

It was a bit trickier to position than with an inline SVG but works just as well. (Could use CSS custom properties or pre-processor variables to keep the height and padding easy to read.)

To edit the colors, you need to edit the URL-encoded SVG itself.

Pay attention (like in the first demo) to a change in the viewBox to get rid of unwanted spaces in the SVG. (Another option would be to draw a different SVG.)

Another thing to pay attention to here is the background-size set to 100% 100% to get it to stretch in both directions.

When SET QUOTED_IDENTIFIER is OFF, literal strings in expressions can be delimited by single or double quotation marks.

If a literal string is delimited by double quotation marks, the string can contain embedded single quotation marks, such as apostrophes.

For Linux You can also use /proc/self/statm to get a single line of numbers containing key process memory information which is a faster thing to process than going through a long list of reported information as you get from proc/self/status

See http://man7.org/linux/man-pages/man5/proc.5.html

   /proc/[pid]/statm
          Provides information about memory usage, measured in pages.
          The columns are:

              size       (1) total program size
                         (same as VmSize in /proc/[pid]/status)
              resident   (2) resident set size
                         (same as VmRSS in /proc/[pid]/status)
              shared     (3) number of resident shared pages (i.e., backed by a file)
                         (same as RssFile+RssShmem in /proc/[pid]/status)
              text       (4) text (code)
              lib        (5) library (unused since Linux 2.6; always 0)
              data       (6) data + stack
              dt         (7) dirty pages (unused since Linux 2.6; always 0)

You can access the first element adding the following code to the highlight function

$(this).find(".selected td:first").html()

Working Code:JSFIDDLE

I'd just make a little function for that. Toss in the two values you need to know the difference between and have it subtract the smaller from the larger value. Something like:

CREATE FUNCTION [dbo].[NumDifference] 
    (   @p1 FLOAT,
        @p2 FLOAT )
RETURNS FLOAT
AS
BEGIN
    DECLARE @Diff FLOAT
    IF @p1 > @p2 SET @Diff = @p1 - @p2 ELSE SET @Diff = @p2 - @p1
    RETURN @Diff
END

In a query to get the difference between column a and b:

SELECT a, b, dbo.NumDifference(a, b) FROM YourTable

the tip of your current branch is behind its remote counterpart means that there have been changes on the remote branch that you don’t have locally. and git tells you import new changes from REMOTE and merge it with your code and then push it to remote.

You can use this command to force changes to server with local repo ().

git push -f origin master

with -f tag you will override Remote Brach code with your code.

I have found an app on the store which can show the name / process of a log. Since Android Studio just puts a (?) on the logs being generated by the other processes, I found it useful to know which process is generating this log. But still this app is missing the filter by the process name. You can find it here.

I think this is you want:

Here is the demo:http://jsfiddle.net/anish/aFBmN/

In controller:

function innerItem($scope, $element){
    var jQueryInnerItem = $($element); 
}

Align the table to center.

<table width="100%" border="0" cellspacing="0" cellpadding="0">
    <tr>
        <td align="center">
            Your Content
        </td>
    </tr>
</table>

Where you have "your content" if it is a table, set it to the desired width and you will have centred content.

You can't do this within the Python program, because the shell decides which version to use if you a shebang line.

If you aren't using a shell with a shebang line and just type python myprogram.py it uses the default version unless you decide specifically which Python version when you type pythonXXX myprogram.py which version to use.

Once your Python program is running you have already decided which Python executable to use to get the program running.

virtualenv is for segregating python versions and environments, it specifically exists to eliminate conflicts.

Use -d (full list of file tests)

if (-d "cgi-bin") {
    # directory called cgi-bin exists
}
elsif (-e "cgi-bin") {
    # cgi-bin exists but is not a directory
}
else {
    # nothing called cgi-bin exists
}

As a note, -e doesn't distinguish between files and directories. To check if something exists and is a plain file, use -f.

There's a shortcut to delete the branch in the origin:

git push origin :<branch_name>

Which is the same as doing git push origin --delete <branch_name>

an abstract method must be call override in derived class other wise it will give compile-time error and in virtual you may or may not override it's depend if it's good enough use it

Example:

abstract class twodshape
{
    public abstract void area(); // no body in base class
}

class twodshape2 : twodshape
{
    public virtual double area()
    {
        Console.WriteLine("AREA() may be or may not be override");
    }
}

The solution I found to work the best was using a subquery like this:

SELECT 
    col1, col2, 
    (
        SELECT COUNT(*) 
        FROM Table1
        WHERE col1 = t1.col1
        AND col2 = t1.col2
        AND col3 > t1.col3
    ) AS intRow
FROM Table1 t1

The PARTITION BY columns just get compared with '=' and separated by AND. The ORDER BY columns would be compared with '<' or '>', and separated by OR.

I've found this to be very flexible, even if it is a little bit costly.

Assuming you mean the HTML type RGB codes (called Hex codes, such as #FFCC66), use the ColorTranslator class:

System.Drawing.Color col = System.Drawing.ColorTranslator.FromHtml("#FFCC66");

If, however you are using an ARGB hex code, you can use the ColorConverter class from the System.Windows.Media namespace:

Color col = ColorConverter.ConvertFromString("#FFDFD991") as Color;
//or      = (Color) ColorConverter.ConvertFromString("#FFCC66") ;

In my case, I only updated the custom view.

// DO NOT LIKE THIS
customView.layoutIfNeeded()    // Change to view.layoutIfNeeded()
UIView.animate(withDuration: 0.5) {
   customViewConstraint.constant = 100.0
   customView.layoutIfNeeded() // Change to view.layoutIfNeeded()
}

Although this thread dates back to 2014, the issue can still be current to many of us. Here is how I dealt with it in a jQuery 1.12 /PHP 5.6 context:

• jQuery sent its XHR request using only limited headers; only 'Origin' was sent.
• No preflight request was needed.
• The server only had to detect such a request, and add the "Access-Control-Allow-Origin: " . $_SERVER['HTTP_ORIGIN'] header, after detecting that this was a cross-origin XHR.

PHP Code sample:

if (!empty($_SERVER['HTTP_ORIGIN'])) {
    // Uh oh, this XHR comes from outer space...
    // Use this opportunity to filter out referers that shouldn't be allowed to see this request
    if (!preg_match('@\.partner\.domain\.net$@'))
        die("End of the road if you're not my business partner.");

    // otherwise oblige
    header("Access-Control-Allow-Origin: " . $_SERVER['HTTP_ORIGIN']);
}
else {
    // local request, no need to send a specific header for CORS
}

In particular, don't add an exit; as no preflight is needed.

Be careful, the solution proposed with $a = array_combine($a, $a); will not work for numeric values.

I for example wanted to have a memory array(128,256,512,1024,2048,4096,8192,16384) to be the keys as well as the values however PHP manual states:

If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended.

So I solved it like this:

foreach($array as $key => $val) {
    $new_array[$val]=$val;
}

Please see my answer here:

https://stackoverflow.com/a/24844618/2293304

It's a long and ugly, but reliable and efficient solution.

It resolves a few problems which are not addressed by the other answerers:

• It correctly handles symbolic links, including not calling shutil.rmtree() on a symbolic link (which will pass the os.path.isdir() test if it links to a directory).
• It handles read-only files nicely.

I'm using

$('#elem').val('xyz');

to select the option element that has value='xyz'

You could convert the dataframe to be a single column with stack (this changes the shape from 5x3 to 15x1) and then take the standard deviation:

df.stack().std()         # pandas default degrees of freedom is one

Alternatively, you can use values to convert from a pandas dataframe to a numpy array before taking the standard deviation:

df.values.std(ddof=1)    # numpy default degrees of freedom is zero

Unlike pandas, numpy will give the standard deviation of the entire array by default, so there is no need to reshape before taking the standard deviation.

A couple of additional notes:

• The numpy approach here is a bit faster than the pandas one, which is generally true when you have the option to accomplish the same thing with either numpy or pandas. The speed difference will depend on the size of your data, but numpy was roughly 10x faster when I tested a few different sized dataframes on my laptop (numpy version 1.15.4 and pandas version 0.23.4).

• The numpy and pandas approaches here will not give exactly the same answers, but will be extremely close (identical at several digits of precision). The discrepancy is due to slight differences in implementation behind the scenes that affect how the floating point values get rounded.

I'm new to the site, and couldn't figure how to comment on a previous answer, which is what I feel this should be. I also couldn't up vote Jeff's post, which I believe gave me my answer. Anyways...

While I can see how some of the great posts, and subsequent tweaks, work, I only have read access to the database, so no UDF, SP or view-based solutions work for me. So Ed Harper's solution looked good, except for VenkateswarluAvula's comment that you can not pass a comma-separated string as a parameter into an WHERE IN clause and expect it to work as you need. But Jeff's solution to the ORACLE 10g fills that gap. I put those together with Russell Christopher's blog post at http://blogs.msdn.com/b/bimusings/archive/2007/05/07/how-do-you-set-select-all-as-the-default-for-multi-value-parameters-in-reporting-services.aspx and I have my solution:

Create your multi-select parameter MYPARAMETER using whatever source of available values (probably a dataset). In my case, the multi-select was from a bunch of TEXT entries, but I'm sure with some tweaking it would work with other types. If you want Select All to be the default position, set the same source as the default. This gives you your user interface, but the parameter created is not the parameter passed to my SQL.

Skipping ahead to the SQL, and Jeff's solution to the WHERE IN (@MYPARAMETER) problem, I have a problem all my own, in that 1 of the values ('Charge') appears in one of the other values ('Non Charge'), meaning the CHARINDEX might find a false-positive. I needed to search the parameter for the delimited value both before and after. This means I need to make sure the comma-separated list has a leading and trailling comma as well. And this is my SQL snippet:

where ...
and CHARINDEX(',' + pitran.LINEPROPERTYID + ',', @MYPARAMETER_LIST) > 0

The bit in the middle is to create another parameter (hidden in production, but not while developing) with:

• A name of MYPARAMETER_LIST
• A type of Text
• A single available value of ="," + join(Parameters!MYPARAMETER.Value,",") + "," and a label that
  doesn't really matter (since it will not be displayed).
• A default value exactly the same
• Just to be sure, I set Always Refresh in both parameters' Advanced properties

It is this parameter which gets passed to SQL, which just happens to be a searchable string but which SQL handles like any piece of text.

I hope putting these fragments of answers together helps somebody find what they're looking for.

It means to interpret the string literally (that is, you cannot escape any characters within the string if you use the @ prefix). It enhances readability in cases where it can be used.

For example, if you were working with a UNC path, this:

@"\\servername\share\folder"

is nicer than this:

"\\\\servername\\share\\folder"

This error can occur on anything that requires elevated privileges in Windows.

It happens when the "Application Information" service is disabled in Windows services. There are a few viruses that use this as an attack vector to prevent people from removing the virus. It also prevents people from installing software to remove viruses.

The normal way to fix this would be to run services.msc, or to go into Administrative Tools and run "Services". However, you will not be able to do that if the "Application Information" service is disabled.

Instead, reboot your computer into Safe Mode (reboot and press F8 until the Windows boot menu appears, select Safe Mode with Networking). Then run services.msc and look for services that are designated as "Disabled" in the Startup Type column. Change these "Disabled" services to "Automatic".

Make sure the "Application Information" service is set to a Startup Type of "Automatic".

When you are done enabling your services, click Ok at the bottom of the tool and reboot your computer back into normal mode. The problem should be resolved when Windows reboots.

Jinja 2.6 does not have the map function. So an alternate way of doing this would be:

set_fact: foo="{% for i in bar_result.results %}{{ i.ansible_facts.foo_item }}{%endfor%}"

Memory management in Linux is a bit tricky to understand, and I can't say I fully understand it yet, but I'll try to share a little bit of my experience and knowledge.

Short answer to your question: Yes there are other stuff included than whats in the list.

What's being shown in your list is applications run in userspace. The kernel uses memory for itself and modules, on top of that it also has a lower limit of free memory that you can't go under. When you've reached that level it will try to free up resources, and when it can't do that anymore, you end up with an OOM problem.

From the last line of your list you can read that the kernel reports a total-vm usage of: 1498536kB (1,5GB), where the total-vm includes both your physical RAM and swap space. You stated you don't have any swap but the kernel seems to think otherwise since your swap space is reported to be full (Total swap = 524284kB, Free swap = 0kB) and it reports a total vmem size of 1,5GB.

Another thing that can complicate things further is memory fragmentation. You can hit the OOM killer when the kernel tries to allocate lets say 4096kB of continous memory, but there are no free ones availible.

Now that alone probably won't help you solve the actual problem. I don't know if it's normal for your program to require that amount of memory, but I would recommend to try a static code analyzer like cppcheck to check for memory leaks or file descriptor leaks. You could also try to run it through Valgrind to get a bit more information out about memory usage.

var regex = new RegExp("^[A-Za-z0-9? ,_-]+$");
            var key = String.fromCharCode(event.charCode ? event.which : event.charCode);
            if (!regex.test(key)) {
                event.preventDefault();
                return false;
            }

in the regExp [A-Za-z0-9?spaceHere,_-] there is a literal space after the question mark '?'. This matches space. Others like /^[-\w\s]+$/ and /^[a-z\d\-_\s]+$/i were not working for me.

As to your bonus question, try if (jQuery.inArray(jQuery("input:first").val(), ar) < 0)

You could also do this if you think it's more clear:

  && columnname != c
{
   if (checkbox.checked || columnname != A2)
   {
      "statement 1"
   }
}

Go to Build Settings tab, and then change the Product Bundle Identifier to another name. It works in mine.

Iteration is synonymous with sprint, sprint is just the Scrum terminology.

On the question about sprint length, the only caution I would note is that in Scrum you are using the past sprints to gain a level of predictability on your teams ability to deliver on their commitments for the sprint. They do this by developing a velocity over a number of sprints. A change in the team members or the length of the sprint are factors that will affect the velocity for a sprint, over past sprints.

Just as background, velocity is the sum of estimation points assigned to the backlog items, or stories, that were completely finished during that sprint. Most Agile proponents (Mike Cohn, Ken Schwaber and Jeff Sutherland for instance), recommend that teams use "the recent weather" to base their future estimations on how much they think they can commit to in a sprint. This means using the average from the last few sprints as the basis for an estimate in the upcoming sprint planning session.

Once again, varying the sprint length reduces your teams ability to provide that velocity statistic which the team uses for sprint planning, and the product owner uses for release planning (i.e. predicting when the project will end or what will be in the project at the end).

I recommend Mike Cohn's book on Agile Estimating and Planning to provide an overview of the way sprints, estimation and planning all can fit together.

There definitely is... Use the spawn, expect, and send commands:

spawn test.sh
expect "Are you sure you want to continue connecting (yes/no)?"
send "yes"

There are more examples all over Stack Overflow, see: Help with Expect within a bash script

You may need to install these commands first, depending on your system.

You can try this:

#!/bin/sh
nohup java -jar /web/server.jar &

The & symbol, switches the program to run in the background.

The nohup utility makes the command passed as an argument run in the background even after you log out.

You could write a function that will convert and format this array as string. Even better: use FireBug for debugging instead of alerts.

You can see whether the output of the following code is 0 or not.

'import re
x='  beer   '
len(re.findall('\s', x))

Namespaces are packages essentially. They can be used like this:

namespace MyNamespace
{
  class MyClass
  {
  };
}

Then in code:

MyNamespace::MyClass* pClass = new MyNamespace::MyClass();

Or, if you want to always use a specific namespace, you can do this:

using namespace MyNamespace;

MyClass* pClass = new MyClass();

Edit: Following what bernhardrusch has said, I tend not to use the "using namespace x" syntax at all, I usually explicitly specify the namespace when instantiating my objects (i.e. the first example I showed).

And as you asked below, you can use as many namespaces as you like.

It seems to me the easiest way to use the following:

wget https://github.com/name/folder/file.zip?raw=true

Which seems the sort of thing you're looking for.

It basically tells the program when you encounter an error just continue at the next line.

You would want to replace all spaces with   (non-breaking space) and all new lines \n with <br> (line break in html). This should achieve the result you're looking for.

body = body.replace(' ', '&nbsp;').replace('\n', '<br>');

Something of that nature.

Here is an example:

Process.Start("CMD", "/C Pause")


/C  Carries out the command specified by string and then terminates
/K  Carries out the command specified by string but remains

And here is a extended function: (Notice the comment-lines using CMD commands.)

In C, the compiler is allowed to dictate some alignment for every primitive type. Typically the alignment is the size of the type. But it's entirely implementation-specific.

Padding bytes are introduced so every object is properly aligned. Reordering is not allowed.

Possibly every remotely modern compiler implements #pragma pack which allows control over padding and leaves it to the programmer to comply with the ABI. (It is strictly nonstandard, though.)

From C99 §6.7.2.1:

12 Each non-bit-field member of a structure or union object is aligned in an implementation- defined manner appropriate to its type.

13 Within a structure object, the non-bit-field members and the units in which bit-fields reside have addresses that increase in the order in which they are declared. A pointer to a structure object, suitably converted, points to its initial member (or if that member is a bit-field, then to the unit in which it resides), and vice versa. There may be unnamed padding within a structure object, but not at its beginning.

#this is a function for a square matrix so on the while loop rows does not have to be less than cols.
#you can make your own condition. But if you want your a square matrix, use this code.

import random

import numpy as np

def random_matrix(R, cols):

        matrix = []

        rows =  0

        while  rows < cols:

            N = random.sample(R, cols)

            matrix.append(N)

            rows = rows + 1

    return np.array(matrix)

print(random_matrix(range(10), 5))

I can't believe the accepted answer has so many upvotes -- it's a horrible method.

Here's the correct way to do it, with date_trunc:

   SELECT date_trunc('month', txn_date) AS txn_month, sum(amount) as monthly_sum
     FROM yourtable
 GROUP BY txn_month

It's bad practice but you might be forgiven if you use

 GROUP BY 1

in a very simple query.

You can also use

 GROUP BY date_trunc('month', txn_date)

if you don't want to select the date.

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

You can check if the rowId is equal to 0.

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

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

If you're trying to link to something, rather than do it from code you can redirect your request through: http://getaspost.appspot.com/

HTML

<form id="some_form">
<!-- some form elements -->

and jquery

$("#some_form").reset();

Maybe this will help

Here's an alternative that works well for readability if you have the Binding in the middle of the string or multiple bindings:

<TextBlock>
  <Run Text="Temperature is "/>
  <Run Text="{Binding CelsiusTemp}"/>
  <Run Text="°C"/>  
</TextBlock>

<!-- displays: 0°C (32°F)-->
<TextBlock>
  <Run Text="{Binding CelsiusTemp}"/>
  <Run Text="°C"/>
  <Run Text=" ("/>
  <Run Text="{Binding Fahrenheit}"/>
  <Run Text="°F)"/>
</TextBlock>

The Array.prototype.shift method removes the first element from an array, and returns it. It modifies the original array.

var a = [1,2,3]
// [1,2,3]
a.shift()
// 1
a
//[2,3]

placeBets(betList, stakeAmt) is an instance method not a static method. You need to create an instance of CBetfairAPI first:

MyBetfair api = new MyBetfair();
ArrayList bets = api.placeBets(betList, stakeAmt);

Here i have created an Helper class to use preferences in android.

This is the helper class:

public class PrefsUtil {

public static SharedPreferences getPreference() {
    return PreferenceManager.getDefaultSharedPreferences(Applicatoin.getAppContext());
}

public static void putBoolean(String key, boolean value) {
    getPreference().edit().putBoolean(key, value)
            .apply();
}

public static boolean getBoolean(String key) {
    return getPreference().getBoolean(key, false);
}

public static void putInt(String key, int value) {

    getPreference().edit().putInt(key, value).apply();

}

public static void delKey(String key) {

    getPreference().edit().remove(key).apply();

}

}

Assuming TableA as an entity of table TableA, and TableADBEntities as DB Entity class,

1. LINQ Method

IQueryable<TableA> result;
using (var context = new TableADBEntities())
{
   result = context.TableA.Select(s => s);
}

2. LINQ-to-SQL Query

IQueryable<TableA> result;
using (var context = new TableADBEntities())
{
   var qry = from s in context.TableA
               select s;
   result = qry.Select(s => s);
}

Native SQL can also be used as:

3. Native SQL

IList<TableA> resultList;
using (var context = new TableADBEntities())
{
   resultList = context.TableA.SqlQuery("Select * from dbo.TableA").ToList();
}

Note: dbo is a default schema owner in SQL Server. One can construct a SQL SELECT query as per the database in the context.

I think the current green answer is bad , why you might ask?

• It can require to add a lot of code
• It requires you to list all Lists to be copied and do this

The way serialization is also bad imo, you might have to add Serializable all over the place.

So what is the solution:

Java Deep-Cloning library The cloning library is a small, open source (apache licence) java library which deep-clones objects. The objects don't have to implement the Cloneable interface. Effectivelly, this library can clone ANY java objects. It can be used i.e. in cache implementations if you don't want the cached object to be modified or whenever you want to create a deep copy of objects.

Cloner cloner=new Cloner();
XX clone = cloner.deepClone(someObjectOfTypeXX);

Check it out at https://github.com/kostaskougios/cloning

function insert(&$arr, $value, $index){       
    $lengh = count($arr);
    if($index<0||$index>$lengh)
        return;

    for($i=$lengh; $i>$index; $i--){
        $arr[$i] = $arr[$i-1];
    }

    $arr[$index] = $value;
}

To get a better understanding do watch the below video which demonstrates code in type safe language (C#) and NOT type safe language ( javascript).

http://www.youtube.com/watch?v=Rlw_njQhkxw

Now for the long text.

Type safety means preventing type errors. Type error occurs when data type of one type is assigned to other type UNKNOWINGLY and we get undesirable results.

For instance JavaScript is a NOT a type safe language. In the below code “num” is a numeric variable and “str” is string. Javascript allows me to do “num + str” , now GUESS will it do arithmetic or concatenation .

Now for the below code the results are “55” but the important point is the confusion created what kind of operation it will do.

This is happening because javascript is not a type safe language. Its allowing to set one type of data to the other type without restrictions.

<script>
var num = 5; // numeric
var str = "5"; // string
var z = num + str; // arthimetic or concat ????
alert(z); // displays  “55”
</script>

C# is a type safe language. It does not allow one data type to be assigned to other data type. The below code does not allow “+” operator on different data types.

If you want to just check if they are identical or not, a == b should give you true / false with ordering taken into account.

In case you want to compare elements, you can use numpy for comparison

c = (numpy.array(a) == numpy.array(b))

Here, c will contain an array with 3 elements all of which are true (for your example). In the event elements of a and b don't match, then the corresponding elements in c will be false.

How about:

SimpleDateFormat fmt = new SimpleDateFormat("yyyyMMdd");
return fmt.format(date1).equals(fmt.format(date2));

You can also set the timezone to the SimpleDateFormat, if needed.

Is it possible that the date could actually be outside that range? Does it come from user input? If the answer to either of these questions is yes, then you should always check - otherwise you're leaving your application prone to error.

You can format your date for inclusion in an SQL statement rather easily:

var sqlFormattedDate = myDateTime.Date.ToString("yyyy-MM-dd HH:mm:ss");

Yes, as long as no one is looking over your shoulder at the monitor.

When you have changes on your working copy, from command line do:

git stash 

This will stash your changes and clear your status report

git pull

This will pull changes from upstream branch. Make sure it says fast-forward in the report. If it doesn't, you are probably doing an unintended merge

git stash pop

This will apply stashed changes back to working copy and remove the changes from stash unless you have conflicts. In the case of conflict, they will stay in stash so you can start over if needed.

if you need to see what is in your stash

git stash list

SELECT  (
    SELECT COUNT(*)
    FROM   user_table
) AS tot_user,
(
    SELECT COUNT(*)
    FROM   cat_table
) AS tot_cat,
(
    SELECT COUNT(*)
    FROM   course_table
) AS tot_course

Simply go to the directory where the troubling file is, type touch * without quotes in the console, and you should be good.

Just to add onto the already great answers, you might want to add multiple labels in your project so doing all of this (setting size, style etc) will be a pain. To solve this, you can create a separate UILabel class.

  import UIKit

  class MyLabel: UILabel {

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        initializeLabel()
    }

    override init(frame: CGRect) {
        super.init(frame: frame)
        initializeLabel()
    }

    func initializeLabel() {

        self.textAlignment = .left
        self.font = UIFont(name: "Halvetica", size: 17)
        self.textColor = UIColor.white

    }

}

To use it, do the following

import UIKit

class ViewController: UIViewController {

     var myLabel: MyLabel()

     override func viewDidLoad() {
          super.viewDidLoad()

          myLabel = MyLabel(frame: CGRect(x: self.view.frame.size.width / 2, y: self.view.frame.size.height / 2, width: 100, height: 20))
          self.view.addSubView(myLabel)
     }


}

No for the moment.

I doubt it will be possible for the future for ActiveX support will be discontinued in near future (as MS stated).

Look here about HTML Object tag, but not anything will be accepted. You should try.

Here's a simplified version in vanilla JavaScript to obtain a single IP address:

function getServerIp() {

  var os = require('os');
  var ifaces = os.networkInterfaces();
  var values = Object.keys(ifaces).map(function(name) {
    return ifaces[name];
  });
  values = [].concat.apply([], values).filter(function(val){
    return val.family == 'IPv4' && val.internal == false;
  });

  return values.length ? values[0].address : '0.0.0.0';
}

My answer here might solve your problem as well:

https://stackoverflow.com/a/27967674/543814

• Instead of Replace, you would use Match.
• Instead of group $1, you would read group $2.
• Group $2 was made non-capturing there, which you would avoid.

Example:

Regex.Match("50% of 50% is 25%", "(\d+\%)|(.+?)");

The first capturing group specifies the pattern that you wish to avoid. The last capturing group captures everything else. Simply read out that group, $2.

The most voted answer is for solving this specific problem posted by OP, where the content (text) was being wrapped inside an inline-block element. Some cases may be about centering a normal element vertically inside a container, which also applied in my case, so for that all you need is:

align-self: center;

There is now (as of v1.10.7) a fourth way to instantiate mocks, which is using a JUnit4 rule called MockitoRule.

@RunWith(JUnit4.class)   // or a different runner of your choice
public class YourTest
  @Rule public MockitoRule rule = MockitoJUnit.rule();
  @Mock public YourMock yourMock;

  @Test public void yourTestMethod() { /* ... */ }
}

JUnit looks for subclasses of TestRule annotated with @Rule, and uses them to wrap the test Statements that the Runner provides. The upshot of this is that you can extract @Before methods, @After methods, and even try...catch wrappers into rules. You can even interact with these from within your test, the way that ExpectedException does.

MockitoRule behaves almost exactly like MockitoJUnitRunner, except that you can use any other runner, such as Parameterized (which allows your test constructors to take arguments so your tests can be run multiple times), or Robolectric's test runner (so its classloader can provide Java replacements for Android native classes). This makes it strictly more flexible to use in recent JUnit and Mockito versions.

In summary:

• Mockito.mock(): Direct invocation with no annotation support or usage validation.
• MockitoAnnotations.initMocks(this): Annotation support, no usage validation.
• MockitoJUnitRunner: Annotation support and usage validation, but you must use that runner.
• MockitoRule: Annotation support and usage validation with any JUnit runner.

See also: How JUnit @Rule works?

In My case @uncaught_exceptions's answer didn't work, I had to use List.class instead of java.lang.reflect.Type:

String jsonDuplicatedItems = request.getSession().getAttribute("jsonDuplicatedItems").toString();
List<Map.Entry<Product, Integer>> entries = gson.fromJson(jsonDuplicatedItems, List.class);

I encountered the same problem and Paul's Answer wasn't an option since it was RDS. Replacing the tab with the commas did not work as the data had embedded commas & tabs. I found that the mycli which is a drop-in alternative for the mysql-client supports csv output outof the box with the --csv flag

mycli db_name --csv -e "select * from flowers" > flowers.csv

Python iterable can be summed like so - [sum(range(10)[1:])] . This sums all elements from the list except the first element.

>>> atuple = (1,2,3,4,5)
>>> sum(atuple)
15
>>> alist = [1,2,3,4,5]
>>> sum(alist)
15

Windows (unlike some other OS's, like Linux), uses CR+LF for line breaks:

• CR = 13 = 0x0D = ^M = \r = carriage return

• LF = 10 = 0x0A = ^J = \n = new line

The characters need to be in that order, if you want the line breaks to be consistently visible when copied to other Windows programs. So the Excel function would be:

=SUBSTITUTE(A1,",",CHAR(13) & CHAR(10))

There are several ways to do a cross join or cartesian product:

SELECT column_names FROM table1 CROSS JOIN table2;

SELECT column_names FROM table1, table2;

SELECT column_names FROM table1 JOIN table2;

Neglecting the on condition in the third case is what results in a cross join.

I just found a real-world application and will use it more often now, I think.

If you use jQuery events, sometimes you want to write a more generic function which may also be called directly (without event). You can use instanceof to check if the first parameter of your function is an instance of jQuery.Event and react appropriately.

var myFunction = function (el) {                
    if (el instanceof $.Event) 
        // event specific code
    else
        // generic code
};

$('button').click(recalc);    // Will execute event specific code
recalc('myParameter');  // Will execute generic code

In my case, the function needed to calculate something either for all (via click event on a button) or only one specific element. The code I used:

var recalc = function (el) { 
    el = (el == undefined || el instanceof $.Event) ? $('span.allItems') : $(el);
    // calculate...
};

Just use MultipleActiveResultSets=True in your connection string.

1. Launch Android Studio application
2. Choose Project Settings
3. Choose Plugin from disk, if on disk then choose that location of *.jar, in my case is GenyMotion jar
4. Click on Apply and OK.
5. Then Android studio will ask for Restart.

That's all Folks!

I was missing a React Fragment:

function Bar({ children }) {

  return (
    <div>
     {children}
    </div>
  );
}

function Foo() {
  return (
    <Bar>
      <Baz/>
      <Qux/>
    </Bar>
  );
}

The code above throws the error above. But this fixes it:

<Bar>
  <>
    <Baz/>
    <Qux/>
  </>
</Bar>

To add to this answer. I just found out that it will also break down if you use a hyphen in your form name (Angular 1.3):

So this will not work:

<form name="my-form">
    <input name="myText" type="text" ng-model="mytext" required />
    <button ng-disabled="my-form.$invalid">Save</button>
</form>

Define your own custom view with title text, then pass LayoutParams to setCustomView(), as Sergii says.

ActionBar actionBar = getSupportActionBar()
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM); 
actionBar.setCustomView(getLayoutInflater().inflate(R.layout.action_bar_home, null),
        new ActionBar.LayoutParams(
                ActionBar.LayoutParams.WRAP_CONTENT,
                ActionBar.LayoutParams.MATCH_PARENT,
                Gravity.CENTER
        )
);

EDITED: At least for width, you should use WRAP_CONTENT or your navigation drawer, app icon, etc. WON'T BE SHOWN (custom view shown on top of other views on action bar). This will occur especially when no action button is shown.

EDITED: Equivalent in xml layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="center_horizontal"
    android:orientation="vertical">

This doesn't require LayoutParams to be specified.

actionBar.setCustomView(getLayoutInflater().inflate(R.layout.action_bar_home, null);

Spring MVC is deeply integreated in Spring, Struts MVC is not.

Few years later, want to suggest just for this: https://github.com/casey/just

action v1 v2=default:
    @echo 'take action on {{v1}} and {{v2}}...'

The replace method is what you're looking for.

For example:

String replacedString = someString.replace("HelloBrother", "Brother");

First of all open visual studio code settings in json and add following arguments after "[python]":{}

To get the numbers after decimal point, you can do this:-

read num1 num2
div=`echo $num1 / $num2 | bc -l`
echo $div

If you are using Webdriver then the item you are looking for is Selected.

Often times in the render of the checkbox doesn't actually apply the attribute checked unless specified.

So what you would look for in Selenium Webdriver is this

isChecked = e.findElement(By.tagName("input")).Selected;

As there is no Selected in WebDriver Java API, the above code should be as follows:

isChecked = e.findElement(By.tagName("input")).isSelected();

After declaring the array

int boardAux[length][length];

the simplest way to assign the initial values as zero is using for loop, even if it may be a bit lengthy

int i, j;
for (i = 0; i<length; i++)
{
    for (j = 0; j<length; j++)
        boardAux[i][j] = 0;
}

let qs = event.queryStringParameters;
const query = Object.keys(qs).map(key => key + '=' + qs[key]).join('&');

Try to replace the

padding: 2px 30px 2px 2px;

with

padding: 2px 2px 2px 2px;

It should work.

For MySQL, use:

DESCRIBE name_of_table;

This also works for Oracle as long as you are using SQL*Plus, or Oracle's SQL Developer.

An easy solution that doesn't involve resorting to JavaScript and will not break CSS transforms is to simply have a non-scrolling element, the same size as your scrolling element, absolute-positioned over it.

The basic HTML structure would be

CSS

<style>
    .parent-to-position-by {
        position: relative;
        top: 40px; /* just to show it's relative positioned */
    }
    .scrolling-contents {
        display: inline-block;
        width: 100%;
        height: 200px;
        line-height: 20px;
        white-space: nowrap;
        background-color: #CCC;
        overflow: scroll;
    }
    .fixed-elements {
        display: inline-block;
        position: absolute;
        top: 0;
        left: 0;
    }
    .fixed {
        position: absolute; /* effectively fixed */
        top: 20px;
        left: 20px;
        background-color: #F00;
        width: 200px;
        height: 20px;
    }
</style>

HTML

<div class="parent-to-position-by">
    <div class="fixed-elements">
        <div class="fixed">
            I am &quot;fixed positioned&quot;
        </div>
    </div>
    <div class="scrolling-contents">
        Lots of contents which may be scrolled.
    </div>
</div>

• parent-to-position-by would be the relative div to position something fixed with respect to.
• scrolling-contents would span the size of this div and contain its main contents
• fixed-elements is just an absolute-positioned div spanning the same space over top of the scrolling-contents div.
• by absolute-positioning the div with the fixed class, it achieves the same effect as if it were fixed-positioned with respect to the parent div. (or the scrolling contents, as they span that full space)

Here's a js-fiddle with a working example

The c variable already contains the char code!

"string".each_byte do |c|
    puts c
end

yields

115
116
114
105
110
103

DONE=false
until $DONE
do
  read line || DONE=true
  echo $line
done < blah.txt

How to use `while read` (Bash) to read the last line in a file if there’s no newline at the end of the file?

You can use this code:

This example takes a backup of sugarcrm database and dumps the output to sugarcrm.sql

# mysqldump -u root -ptmppassword sugarcrm > sugarcrm.sql

# mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql

The sugarcrm.sql will contain drop table, create table and insert command for all the tables in the sugarcrm database. Following is a partial output of sugarcrm.sql, showing the dump information of accounts_contacts table:

--

-- Table structure for table accounts_contacts

DROP TABLE IF EXISTS `accounts_contacts`;
SET @saved_cs_client = @@character_set_client;
SET character_set_client = utf8;
CREATE TABLE `accounts_contacts` (
`id` varchar(36) NOT NULL,
`contact_id` varchar(36) default NULL,
`account_id` varchar(36) default NULL,
`date_modified` datetime default NULL,
`deleted` tinyint(1) NOT NULL default '0',
PRIMARY KEY (`id`),
KEY `idx_account_contact` (`account_id`,`contact_id`),
KEY `idx_contid_del_accid` (`contact_id`,`deleted`,`account_id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
SET character_set_client = @saved_cs_client;

You can write:

python
import keras
keras.__version__

It's simpler than I initially thought.. Basically you have a page that does nothing, until the data you want to send is available (say, a new message arrives).

Here is a really basic example, which sends a simple string after 2-10 seconds. 1 in 3 chance of returning an error 404 (to show error handling in the coming Javascript example)

msgsrv.php

<?php
if(rand(1,3) == 1){
    /* Fake an error */
    header("HTTP/1.0 404 Not Found");
    die();
}

/* Send a string after a random number of seconds (2-10) */
sleep(rand(2,10));
echo("Hi! Have a random number: " . rand(1,10));
?>

Note: With a real site, running this on a regular web-server like Apache will quickly tie up all the "worker threads" and leave it unable to respond to other requests.. There are ways around this, but it is recommended to write a "long-poll server" in something like Python's twisted, which does not rely on one thread per request. cometD is an popular one (which is available in several languages), and Tornado is a new framework made specifically for such tasks (it was built for FriendFeed's long-polling code)... but as a simple example, Apache is more than adequate! This script could easily be written in any language (I chose Apache/PHP as they are very common, and I happened to be running them locally)

Then, in Javascript, you request the above file (msg_srv.php), and wait for a response. When you get one, you act upon the data. Then you request the file and wait again, act upon the data (and repeat)

What follows is an example of such a page.. When the page is loaded, it sends the initial request for the msgsrv.php file.. If it succeeds, we append the message to the #messages div, then after 1 second we call the waitForMsg function again, which triggers the wait.

The 1 second setTimeout() is a really basic rate-limiter, it works fine without this, but if msgsrv.php always returns instantly (with a syntax error, for example) - you flood the browser and it can quickly freeze up. This would better be done checking if the file contains a valid JSON response, and/or keeping a running total of requests-per-minute/second, and pausing appropriately.

If the page errors, it appends the error to the #messages div, waits 15 seconds and then tries again (identical to how we wait 1 second after each message)

The nice thing about this approach is it is very resilient. If the clients internet connection dies, it will timeout, then try and reconnect - this is inherent in how long polling works, no complicated error-handling is required

Anyway, the long_poller.htm code, using the jQuery framework:

As Simon mentioned, this is not possible in the new Facebook API. Pure technically speaking you can do it via browser automation.

• this is against Facebook policy, so depending on the country where you live, this may not be legal
• you'll have to use your credentials / ask user for credentials and possibly store them (storing passwords even symmetrically encrypted is not a good idea)
• when Facebook changes their API, you'll have to update the browser automation code as well (if you can't force updates of your application, you should put browser automation piece out as a webservice)
• this is bypassing the OAuth concept
• on the other hand, my feeling is that I'm owning my data including the list of my friends and Facebook shouldn't restrict me from accessing those via the API

Sample implementation using WatiN:

class FacebookUser
{
  public string Name { get; set; }
  public long Id { get; set; }
}

public IList<FacebookUser> GetFacebookFriends(string email, string password, int? maxTimeoutInMilliseconds)
{
  var users = new List<FacebookUser>();
  Settings.Instance.MakeNewIeInstanceVisible = false;
  using (var browser = new IE("https://www.facebook.com"))
  {
    try
    {
      browser.TextField(Find.ByName("email")).Value = email;
      browser.TextField(Find.ByName("pass")).Value = password;
      browser.Form(Find.ById("login_form")).Submit();
      browser.WaitForComplete();
    }
    catch (ElementNotFoundException)
    {
      // We're already logged in
    }
    browser.GoTo("https://www.facebook.com/friends");
    var watch = new Stopwatch();
    watch.Start();

    Link previousLastLink = null;
    while (maxTimeoutInMilliseconds.HasValue && watch.Elapsed.TotalMilliseconds < maxTimeoutInMilliseconds.Value)
    {
      var lastLink = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
                       && l.GetAttributeValue("data-hovercard").Contains("user.php")
                       && l.Text != null
                     ).LastOrDefault();

      if (lastLink == null || previousLastLink == lastLink)
      {
        break;
      }

      var ieElement = lastLink.NativeElement as IEElement;
      if (ieElement != null)
      {
        var htmlElement = ieElement.AsHtmlElement;
        htmlElement.scrollIntoView();
        browser.WaitForComplete();
      }

      previousLastLink = lastLink;
    }

    var links = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
      && l.GetAttributeValue("data-hovercard").Contains("user.php")
      && l.Text != null
    ).ToList();

    var idRegex = new Regex("id=(?<id>([0-9]+))");
    foreach (var link in links)
    {
      string hovercard = link.GetAttributeValue("data-hovercard");
      var match = idRegex.Match(hovercard);
      long id = 0;
      if (match.Success)
      {
        id = long.Parse(match.Groups["id"].Value);
      }
      users.Add(new FacebookUser
      {
        Name = link.Text,
        Id = id
      });
    }
  }
  return users;
}

Prototype with implementation of this approach (using C#/WatiN) see https://github.com/svejdo1/ShadowApi. It is also allowing dynamic update of Facebook connector that is retrieving a list of your contacts.

Add in activity

requestWindowFeature(Window.FEATURE_NO_TITLE);

and add your style.xml file with the following two lines:

<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>

try this way .eregi("[^A-Za-z0-9.]", $value)

There's some duplicates that touch on this, and nobody really expounds on it. I'll borrow the accepted answer example to illustrate

http.open('POST', url, true);
http.send('lorem=ipsum&name=binny');

I oversimplified this (I use http.onload(function() {}) instead of that answer's older methodology) for the sake of illustration. If you use this as-is, you'll find your server is probably interpreting the POST body as a string and not actual key=value parameters (i.e. PHP won't show any $_POST variables). You must pass the form header in to get that, and do that before http.send()

http.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');

If you're using JSON and not URL-encoded data, pass application/json instead

private static boolean isEncodedText(String val, String... encoding) throws UnsupportedEncodingException { String decodedText = URLDecoder.decode(val, TransformFetchConstants.DEFAULT_CHARSET);

    if(encoding != null && encoding.length > 0){
        decodedText = URLDecoder.decode(val, encoding[0]);
    }

    String encodedText =  URLEncoder.encode(decodedText);

    return encodedText.equalsIgnoreCase(val) || !decodedText.equalsIgnoreCase(val);

}

Calling close and shutdown have two different effects on the underlying socket.

The first thing to point out is that the socket is a resource in the underlying OS and multiple processes can have a handle for the same underlying socket.

When you call close it decrements the handle count by one and if the handle count has reached zero then the socket and associated connection goes through the normal close procedure (effectively sending a FIN / EOF to the peer) and the socket is deallocated.

The thing to pay attention to here is that if the handle count does not reach zero because another process still has a handle to the socket then the connection is not closed and the socket is not deallocated.

On the other hand calling shutdown for reading and writing closes the underlying connection and sends a FIN / EOF to the peer regardless of how many processes have handles to the socket. However, it does not deallocate the socket and you still need to call close afterward.

Regarding a NodeJS implementation, I have added a custom expiryTime field in the object I save in the HASH. Then after a specific period time, I clear the expired HASH entries by using the following code:

client.hgetall(HASH_NAME, function(err, reply) {
    if (reply) {
        Object.keys(reply).forEach(key => {
            if (reply[key] && JSON.parse(reply[key]).expiryTime < (new Date).getTime()) {
                client.hdel(HASH_NAME, key);
            }
        })
    }
});

Don't put the @ before the id

new { id = "1" }

The framework "translate" it in ?Lenght when there is a mismatch in the parameter/route

Calendar.setTime()

It's often useful to look at the signature and description of API methods, not just their name :) - Even in the Java standard API, names can sometimes be misleading.

It is possible to do what you want by using the syntax for generic methods when declaring your doIt() method (notice the addition of <T> between static and void in the method signature of doIt()):

class Clazz<T> {
  static <T> void doIt(T object) {
    // shake that booty
  }
}

I got Eclipse editor to accept the above code without the Cannot make a static reference to the non-static type T error and then expanded it to the following working program (complete with somewhat age-appropriate cultural reference):

public class Clazz<T> {
  static <T> void doIt(T object) {
    System.out.println("shake that booty '" + object.getClass().toString()
                       + "' !!!");
  }

  private static class KC {
  }

  private static class SunshineBand {
  }

  public static void main(String args[]) {
    KC kc = new KC();
    SunshineBand sunshineBand = new SunshineBand();
    Clazz.doIt(kc);
    Clazz.doIt(sunshineBand);
  }
}

Which prints these lines to the console when I run it:

shake that booty 'class com.eclipseoptions.datamanager.Clazz$KC' !!!
shake that booty 'class com.eclipseoptions.datamanager.Clazz$SunshineBand' !!!

I believe this can help you:

$(document).ready(function(){
    var temp = {someKey:"temp value", otherKey:"other value", fooKey:"some value"};
    for (var key in temp) {
        alert('<option value=' + key + '>' + temp[key] + '</option>');
    }
});

You can just set a label on the textview.

MyUITextView.h

@interface MyUITextView : UITextView {
    UILabel* _placeholderLabel;
}

@property(nonatomic, assign)NSString *placeholder;

MyUITextView.m

@implementation MyUITextView

- (id)initWithFrame:(CGRect)frame {
    if (self = [super initWithFrame:frame]) {
        // Create placeholder
        viewFrame = CGRectMake(0, 0, frame.size.width, 15);
        _placeholderLabel = [[UILabel alloc] initWithFrame:viewFrame];
        _placeholderLabel.textColor = [UIColor lightGrayColor];
        [self addSubview:_placeholderLabel];

        // Add text changed notification 
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(textChanged:) name:UITextViewTextDidChangeNotification object:nil];
    }
    return self;
}

- (void)setPlaceholder:(NSString *)placeholder {
    _placeholderLabel.text = placeholder;
}

- (NSString*)placeholder {
    return _placeholderLabel.text;
}

#pragma mark UITextViewTextDidChangeNotification

- (void)textChanged:(NSNotification *)notification {
    _placeholderLabel.hidden = ([self.text lenght] == 0);
}

@end

You cannot insert data because you have a quota of 0 on the tablespace. To fix this, run

ALTER USER <user> quota unlimited on <tablespace name>;

or

ALTER USER <user> quota 100M on <tablespace name>;

as a DBA user (depending on how much space you need / want to grant).

A long rant on personal names

A personal name is either a Polynym (a name with multiple sortable components), a Mononym (a name with only one component), or a Pictonym (a name represented by a picture - this exists due to people like Prince).

A person can have multiple names, playing roles, such as LEGAL, MARITAL, MAIDEN, PREFERRED, SOBRIQUET, PSEUDONYM, etc. You might have business rules, such as "a person can only have one legal name at a time, but multiple pseudonyms at a time".

Some examples:

names: [
  {
    type:"POLYNYM",
    role:"LEGAL",
    given:"George",
    middle:"Herman",
    moniker:"Babe",
    surname:"Ruth",
    generation:"JUNIOR"
  },
  {
    type:"MONONYM",
    role:"SOBRIQUET",
    mononym:"The Bambino" /* mononyms can be more than one word, but only one component */
  },
  {
    type:"MONONYM",
    role:"SOBRIQUET",
    mononym:"The Sultan of Swat"
  }
]

or

names: [
  {
    type:"POLYNYM",
    role:"PREFERRED",
    given:"Malcolm",
    surname:"X"
  },
  {
    type:"POLYNYM",
    role:"BIRTH",
    given:"Malcolm",
    surname:"Little"
  },
  {
    type:"POLYNYM",
    role:"LEGAL",
    given:"Malik",
    surname:"El-Shabazz"
  }
]

or

names:[
  {
    type:"POLYNYM",
    role:"LEGAL",
    given:"Prince",
    middle:"Rogers",
    surname:"Nelson"
  },
  {
    type:"MONONYM",
    role:"SOBRIQUET",
    mononym:"Prince"
  },
  {
    type:"PICTONYM",
    role:"LEGAL",
    url:"http://upload.wikimedia.org/wikipedia/en/thumb/a/af/Prince_logo.svg/130px-Prince_logo.svg.png"
  }
]

or

names:[
  {
    type:"POLYNYM",
    role:"LEGAL",
    given:"Juan Pablo",
    surname:"Fernández de Calderón",
    secondarySurname:"García-Iglesias" /* hispanic people often have two surnames. it can be impolite to use the wrong one. Portuguese and Spaniards differ as to which surname is important */
  }
]

Given names, middle names, surnames can be multiple words such as "Billy Bob" Thornton, or Ralph "Vaughn Williams".

Use @RequestParam

@RequestMapping(value="user", method = RequestMethod.GET)
public @ResponseBody Item getItem(@RequestParam("data") String itemid){

    Item i = itemDao.findOne(itemid);              
    String itemName = i.getItemName();
    String price = i.getPrice();
    return i;
}

I found quite an elegant solution.

As you said, it's fairly easy to execute code located on the parent document. And that's the base of my code, do to just the opposite.

When my iframe loads, I call a function located on the parent document, passing as an argument a reference to a local function, located in the iframe's document. The parent document now has a direct access to the iframe's function thru this reference.

Example:

On the parent:

function tunnel(fn) {
    fn();
}

On the iframe:

var myFunction = function() {
    alert("This work!");
}

parent.tunnel(myFunction);

When the iframe loads, it will call parent.tunnel(YourFunctionReference), which will execute the function received in parameter.

That simple, without having to deal with the all the non-standards methods from the various browsers.

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

git branch -d branch1

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

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

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

git push origin :branch1

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

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

Put very simply, request timeout means there was no response whereas destination unreachable may mean the address specified does not exist i.e. you typed in the wrong IP address.

pm2 start npm --name {appName} -- run {script name}

you can check it by

pm2 list

you can also add time

pm2 restart "id" --log-date-format 'DD-MM HH:mm:ss.SSS' or pm2 restart "id" --time

you can check logs by

pm2 log "id" or pm2 log "appName"

to get logs for all app

pm2 logs

I was also getting this error, I found that it was because I had deleted the Default Application Pool "DefaultAppPool". Re-creating it fixed the problem. Drove me crazy for a few days.

This error will appear if either the web application is mapped to a non-existent app-pool; or if that application pool is stopped.

And to send a largFile

byte[] pdfData = getPDFData();

String fileType = "";

res.setContentType("application/pdf");

httpRes.setContentType("application/.pdf");
httpRes.addHeader("Content-Disposition", "attachment; filename=IDCards.pdf");
httpRes.setStatus(HttpServletResponse.SC_OK);
OutputStream out = res.getOutputStream();
System.out.println(pdfData.length);
         
out.write(pdfData);
System.out.println("sendDone");
out.flush();

The first question you need to ask is whether you really need the ID to be random. Sometime, sequential IDs are good enough.

Now, if you do need it to be random, we first note a generated sequence of numbers that contain no duplicates can not be called random. :p Now that we get that out of the way, the fastest way to do this is to have a Hashtable or HashMap containing all the IDs already generated. Whenever a new ID is generated, check it against the hashtable, re-generate if the ID already occurs. This will generally work well if the number of students is much less than the range of the IDs. If not, you're in deeper trouble as the probability of needing to regenerate an ID increases, P(generate new ID) = number_of_id_already_generated / number_of_all_possible_ids. In this case, check back the first paragraph (do you need the ID to be random?).

Hope this helps.

You can use IntStream.iterate() to get the index:

String[] names = {"Sam","Pamela", "Dave", "Pascal", "Erik"};
List<String> nameList = IntStream.iterate(0, i -> i < names.length, i -> i + 1)
        .filter(i -> names[i].length() <= i)
        .mapToObj(i -> names[i])
        .collect(Collectors.toList());

This only works for Java 9 upwards in Java 8 you can use this:

String[] names = {"Sam","Pamela", "Dave", "Pascal", "Erik"};
List<String> nameList = IntStream.iterate(0, i -> i + 1)
        .limit(names.length)
        .filter(i -> names[i].length() <= i)
        .mapToObj(i -> names[i])
        .collect(Collectors.toList());

You can use setInterval:

var timer = setInterval( myFunction, 1000);

Just declare your function as myFunction or some other name, and then don't bind it to $('.more')'s live event.

The following works for me in Internet Explorer. Note the addition of the table-layout:fixed CSS attribute

td {_x000D_
  border: 1px solid;_x000D_
}

<table style="table-layout: fixed; width: 100%">_x000D_
  <tr>_x000D_
    <td style="word-wrap: break-word">_x000D_
      LongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongLongWord_x000D_
    </td>_x000D_
  </tr>_x000D_
</table>

False, Null, Nothing, 0, Undefined, etc., etc.

Each of these has specific meanings that correlate with actual concepts. Sometimes multiple meanings are overloaded into a single keyword or value.

In C and C++, NULL, False and 0 are overloaded to the same value. In C# they're 3 distinct concepts.

null or NULL usually indicates a lack of value, but usually doesn't specify why. 0 indicates the natural number zero and has type-equivalence to 1, 2, 3, etc. and in languages that support separate concepts of NULL should be treated only a number.

False indicates non-truth. And it used in binary values. It doesn't mean unset, nor does it mean 0. It simply indicates one of two binary values.

Nothing can indicate that the value is specifically set to be nothing which indicates the same thing as null, but with intent.

Undefined in some languages indicates that the value has yet to be set because no code has specified an actual value.

Basically this. It keeps calling itself until its done

void print_folder(string root)
{
    Console.WriteLine(root);
    foreach(var folder in Directory.GetDirectories(root))
    {
        print_folder(folder);
    }
}

Also works with loops!

void pretend_loop(int c)
{
    if(c==0) return;
    print "hi";
    pretend_loop(c-);
}

You can also trying googling it. Note the "Did you mean" (click on it...). http://www.google.com/search?q=recursion&spell=1

I'm sad to say: We are sh*t out of luck on this one.

I'd like to refer you to the author of WhichBrowser: Everybody lies.

Basically, no browser is being honest. No matter if you use Chrome or IE, they both will tell you that they are "Mozilla Netscape" with Gecko and Safari support. Try it yourself on any of the fiddles flying around in this thread:

hims056's fiddle

Hariharan's fiddle

or any other... Try it with Chrome (which might still succeed), then try it with a recent version of IE, and you will cry. Of course, there are heuristics, to get it all right, but it will be tedious to grasp all the edge cases, and they will very likely not work anymore in a year's time.

Take your code, for example:

<div id="example"></div>
<script type="text/javascript">
txt = "<p>Browser CodeName: " + navigator.appCodeName + "</p>";
txt+= "<p>Browser Name: " + navigator.appName + "</p>";
txt+= "<p>Browser Version: " + navigator.appVersion + "</p>";
txt+= "<p>Cookies Enabled: " + navigator.cookieEnabled + "</p>";
txt+= "<p>Platform: " + navigator.platform + "</p>";
txt+= "<p>User-agent header: " + navigator.userAgent + "</p>";
document.getElementById("example").innerHTML=txt;
</script>

Chrome says:

Browser CodeName: Mozilla

Browser Name: Netscape

Browser Version: 5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.115 Safari/537.36

User-agent header: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.115 Safari/537.36

IE says:

Browser CodeName: Mozilla

Browser Name: Netscape

Browser Version: 5.0 (Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3; rv:11.0) like Gecko

Cookies Enabled: true

Platform: Win32

User-agent header: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3; rv:11.0) like Gecko

At least Chrome still has a string that contains "Chrome" with the exact version number. But, for IE you must extrapolate from the things it supports to actually figure it out (who else would boast that they support .NET or Media Center :P), and then match it against the rv: at the very end to get the version number. Of course, even such sophisticated heuristics might very likely fail as soon as IE 12 (or whatever they want to call it) comes out.

I've tested the performance of all the proposed approaches.

Here is the fastest variant I've got.

String.prototype.repeat = function(count) {
    if (count < 1) return '';
    var result = '', pattern = this.valueOf();
    while (count > 1) {
        if (count & 1) result += pattern;
        count >>= 1, pattern += pattern;
    }
    return result + pattern;
};

Or as stand-alone function:

function repeat(pattern, count) {
    if (count < 1) return '';
    var result = '';
    while (count > 1) {
        if (count & 1) result += pattern;
        count >>= 1, pattern += pattern;
    }
    return result + pattern;
}

It is based on artistoex algorithm. It is really fast. And the bigger the count, the faster it goes compared with the traditional new Array(count + 1).join(string) approach.

I've only changed 2 things:

1. replaced pattern = this with pattern = this.valueOf() (clears one obvious type conversion);
2. added if (count < 1) check from prototypejs to the top of function to exclude unnecessary actions in that case.
3. applied optimisation from Dennis answer (5-7% speed up)

UPD

Created a little performance-testing playground here for those who interested.

variable count ~ 0 .. 100:

constant count = 1024:

Use it and make it even faster if you can :)

Easy Solution:
Go to

Project property -> java builder path -> maven -> find c3p0-0.9.5.2.jar

and see the location where the file is stored in the local repository and go to this location and delete the repository manually.

Using d-flex class works well but some other attributes don't work anymore like vertical-align: middle property.

The best way I found to size columns very easily is to use the width attribute with percentage only in thead cells.

<table class="table">
    <thead>
        <tr>
            <th width="25%">25%</th>
            <th width="25%">25%</th>
            <th width="50%">50%</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>25%</td>
            <td>25%</td>
            <td>50%</td>
        </tr>
    </tbody>
</table>

For a large database, I am reluctant to lose the size and speed advantages of the numeric representation. I often end up with a database table representing the Enum.

You can enforce database consistency by declaring a foreign key -- although in some cases it might be better to not declare that as a foreign key constraint, which imposes a cost on every transaction. You can ensure consistency by periodically doing a check, at times of your choosing, with:

SELECT reftable.* FROM reftable
  LEFT JOIN enumtable ON reftable.enum_ref_id = enumtable.enum_id
WHERE enumtable.enum_id IS NULL;

The other half of this solution is to write some test code that checks that the Java enum and the database enum table have the same contents. That's left as an exercise for the reader.

Based on @md-nazrul-islam reply, This is what I did with SCSS:

ul.ui-autocomplete {
    position: absolute;
    top: 100%;
    left: 0;
    z-index: 1000;
    float: left;
    display: none;
    min-width: 160px;
    margin: 0 0 10px 25px;
    list-style: none;
    background-color: #ffffff;
    border: 1px solid #ccc;
    border-color: rgba(0, 0, 0, 0.2);
    //@include border-radius(5px);
    @include box-shadow( rgba(0, 0, 0, 0.1) 0 5px 10px );
    @include background-clip(padding-box);
    *border-right-width: 2px;
    *border-bottom-width: 2px;

    li.ui-menu-item{
        padding:0 .5em;
        line-height:2em;
        font-size:.8em;
        &.ui-state-focus{
            background: #F7F7F7;
        }
    }

}

As mentioned above, there are issues with using the top-most scope in your script file. Here is another issue: The script file might be run from a context that is not the global context in some run-time environment.

It has been proposed to assign the global to window directly. But that is also run-time dependent and does not work in Node etc. It goes to show that portable global variable management needs some careful consideration and extra effort. Maybe they will fix it in future ECMS versions!

For now, I would recommend something like this to support proper global management for all run-time environments:

/**
 * Exports the given object into the global context.
 */
var exportGlobal = function(name, object) {
    if (typeof(global) !== "undefined")  {
        // Node.js
        global[name] = object;
    }
    else if (typeof(window) !== "undefined") {
        // JS with GUI (usually browser)
        window[name] = object;
    }
    else {
        throw new Error("Unkown run-time environment. Currently only browsers and Node.js are supported.");
    }
};


// export exportGlobal itself
exportGlobal("exportGlobal", exportGlobal);

// create a new global namespace
exportGlobal("someothernamespace", {});

It's a bit more typing, but it makes your global variable management future-proof.

Disclaimer: Part of this idea came to me when looking at previous versions of stacktrace.js.

I reckon, one can also use Webpack or other tools to get more reliable and less hackish detection of the run-time environment.

Of course it is right what you say at the beginning, and C logical operator && and || are what you usually use to "connect" conditions (expressions that can be evaluated as true or false); the comma operator is not a logical operator and its use in that example makes no sense, as explained by other users. You can use it e.g. to "concatenate" statements in the for itself: you can initialize and update j altogether with i; or use the comma operator in other ways

#include <stdio.h>

int main(void)  // as std wants
{
  int i, j;

  // init both i and j; condition, we suppose && is the "original"
  // intention; update i and j
  for(i=0, j=2; j>=0 && i<=5; i++, j--)
  {
       printf("%d ", i+j);
  }
  return 0;        
}

Just for completeness, you can also use ORA_DATABASE_NAME.

It might be worth noting that not all of the methods give you the same output:

SQL> select sys_context('userenv','db_name') from dual;

SYS_CONTEXT('USERENV','DB_NAME')
--------------------------------------------------------------------------------
orcl

SQL> select ora_database_name from dual;

ORA_DATABASE_NAME
--------------------------------------------------------------------------------
ORCL.XYZ.COM

SQL> select * from global_name;

GLOBAL_NAME
--------------------------------------------------------------------------------
ORCL.XYZ.COM

Setting android:layout_gravity="bottom|right" worked for me

The JSON spec says this:

An object is an unordered set of name/value pairs.

The important part here is "unordered": it implies uniqueness of keys, because the only thing you can use to refer to a specific pair is its key.

In addition, most JSON libs will deserialize JSON objects to hash maps/dictionaries, where keys are guaranteed unique. What happens when you deserialize a JSON object with duplicate keys depends on the library: in most cases, you'll either get an error, or only the last value for each duplicate key will be taken into account.

For example, in Python, json.loads('{"a": 1, "a": 2}') returns {"a": 2}.

From the many answers I could read, the only given way was to expand the number of variables according to the number of factors. If you have a variable "pet" with levels "dog" and "cat", you would end up with pet_dog and pet_cat.

In my case I wanted to stay with the same number of variables, by just translating the factor variable to a numeric one, in a way that can applied to many variables with many levels, so that cat=1 and dog=0 for instance.

Please find the corresponding solution below:

crime <- data.frame(city = c("SF", "SF", "NYC"),
                    year = c(1990, 2000, 1990),
                    crime = 1:3)

indx <- sapply(crime, is.factor)

crime[indx] <- lapply(crime[indx], function(x){ 
  listOri <- unique(x)
  listMod <- seq_along(listOri)
  res <- factor(x, levels=listOri)
  res <- as.numeric(res)
  return(res)
}
)

I use the following method:

public static <T> T getBean(final String beanName, final Class<T> clazz) {
    ELContext elContext = FacesContext.getCurrentInstance().getELContext();
    return (T) FacesContext.getCurrentInstance().getApplication().getELResolver().getValue(elContext, null, beanName);
}

This allows me to get the returned object in a typed manner.

I have also this problem when I do with XCode project what is exported from cordova framework. Resolution : You have to create Apple-ID and Provisioining-profile by yourself. Because Xcode seems to be unable to create it for you.

You're thinking about this the wrong way. You're thinking in logical steps each time cin or getline is used. Ex. First ask for a number, then ask for a name. That is the wrong way to think about cin. So you run into a race condition because you assume the stream is clear each time you ask for a input.

If you write your program purely for input you'll find the problem:

void main(void)
{
    double num;
    string mystr;

    cin >> num;
    getline(cin, mystr);

    cout << "num=" << num << ",mystr=\'" << mystr << "\'" << endl;
}

In the above, you are thinking, "first get a number." So you type in 123 press enter, and your output will be num=123,mystr=''. Why is that? It's because in the stream you have 123\n and the 123 is parsed into the num variable while \n is still in the stream. Reading the doc for getline function by default it will look in the istream until a \n is encountered. In this example, since \n is in the stream, it looks like it "skipped" it but it worked properly.

For the above to work, you'll have to enter 123Hello World which will properly output num=123,mystr='Hello World'. That, or you put a cin.ignore between the cin and getline so that it'll break into logical steps that you expect.

This is why you need the ignore command. Because you are thinking of it in logical steps rather than in a stream form so you run into a race condition.

Take another code example that is commonly found in schools:

void main(void)
{
    int age;
    string firstName;
    string lastName;

    cout << "First name: ";
    cin >> firstName;

    cout << "Last name: ";
    cin >> lastName;

    cout << "Age: ";
    cin >> age;

    cout << "Hello " << firstName << " " << lastName << "! You are " << age << " years old!" << endl;
}

The above seems to be in logical steps. First ask for first name, last name, then age. So if you did John enter, then Doe enter, then 19 enter, the application works each logic step. If you think of it in "streams" you can simply enter John Doe 19 on the "First name:" question and it would work as well and appear to skip the remaining questions. For the above to work in logical steps, you would need to ignore the remaining stream for each logical break in questions.

Just remember to think of your program input as it is reading from a "stream" and not in logical steps. Each time you call cin it is being read from a stream. This creates a rather buggy application if the user enters the wrong input. For example, if you entered a character where a cin >> double is expected, the application will produce a seemingly bizarre output.

If your model is called BlogPost, it would be:

BlogPost.all.map(&:destroy)

Here you go.

if (!is_dir('path/to/directory')) {
    if (!mkdir('path/to/directory', 0777, true) && !is_dir('path/to/directory')) {
        throw new \RuntimeException(sprintf('Directory "%s" was not created', 'path/to/directory'));
    }
}

fscanf will treat 2 arguments, and thus return 2. Your while statement will be false, hence never displaying what has been read, plus as it has read only 1 line, if is not at EOF, resulting in what you see.

See the documentation on ?merge, which states:

By default the data frames are merged on the columns with names they both have, 
 but separate specifications of the columns can be given by by.x and by.y.

This clearly implies that merge will merge data frames based on more than one column. From the final example given in the documentation:

x <- data.frame(k1=c(NA,NA,3,4,5), k2=c(1,NA,NA,4,5), data=1:5)
y <- data.frame(k1=c(NA,2,NA,4,5), k2=c(NA,NA,3,4,5), data=1:5)
merge(x, y, by=c("k1","k2")) # NA's match

This example was meant to demonstrate the use of incomparables, but it illustrates merging using multiple columns as well. You can also specify separate columns in each of x and y using by.x and by.y.

Access it like any other pointer value:

std::vector<int>* v = new std::vector<int>();

v->push_back(0);
v->push_back(12);
v->push_back(1);

int twelve = v->at(1);
int one = (*v)[2];

// iterate it
for(std::vector<int>::const_iterator cit = v->begin(), e = v->end; 
    cit != e;  ++cit)
{
    int value = *cit;
}

// or, more perversely
for(int x = 0; x < v->size(); ++x)
{
    int value = (*v)[x];
}

// Or -- with C++ 11 support
for(auto i : *v)
{
   int value = i;
}

Just add parameters, split by comma:

UPDATE tablename SET column1 = "value1", column2 = "value2" ....

Not true for the OP, but this error can be caused by using single quotation marks (') instead of double (") for strings.

The JSON spec requires double quotation marks for strings.

E.g:

JSON.parse(`{"myparam": 'myString'}`)

gives the error, whereas

JSON.parse(`{"myparam": "myString"}`)

does not. Note the quotation marks around myString.

1. Go to the log view (to be able to go here go to View -> log view).
2. Double click on the line with the branch label stating that branch. Automatically, it will switch branch. (A prompt will dropdown and say switching branch.)
3. If you have two or more branches on the same line, it will ask you via prompt which branch you want to switch. Choose the specific branch from the dropdown and click ok.

To determine which branch you are now on, look at the side bar, under BRANCHES, you are in the branch that is in BOLD LETTERS.

You have to put the path to the file. For example:

require_once('../web/a.php');

You cannot get the file to require it from internet (with http protocol) it's restricted. The files must be on the same server. With Possibility to see each others (rights)

Dir-1 -
         > Folder-1 -> a.php
Dir-2 -
         > Folder-2 -> b.php

To include a.php inside b.php => require_once('../../Dir-1/Folder-1/a.php');
To include b.php inside a.php => require_once('../../Dir-2/Folder-2/b.php');

Html files do not need to be rendered.
what a render engine does is turn a file that is not an Html file into an Html file.
to send an Html file, just do:

res.sendFile("index.html");

you might need to use __dirname+"/index.html" so express will know the exact path.

It is not at all obvious why one would want to concatenate the (decimal) "ascii values". What is certain is that concatenating them without leading zeroes (or some other padding or a delimiter) is useless -- nothing can be reliably recovered from such an output.

I encounted this error and found that it was because the "strict" parameter was set to true in the tsconfig.json file. Just set it "false" (obviously). In my case I had generated the tsconfig file from the cmd prompt and simply missed the "strict" parameter, which was located further down in the file.

You need to cast your activity from getActivity() to AppCompatActivity first. Here's an example:

((AppCompatActivity) getActivity()).getSupportActionBar().setTitle();

The reason you have to cast it is because getActivity() returns a FragmentActivity and you need an AppCompatActivity

In Kotlin:

(activity as AppCompatActivity).supportActionBar?.title = "My Title"

Just set the property as follows:

When the user press "clear button" or "delete key" do

dtpData.CustomFormat = " "  'An empty SPACE
dtpData.Format = DateTimePickerFormat.Custom

On DateTimePicker1_ValueChanged event do

dtpData.CustomFormat = "dd/MM/yyyy hh:mm:ss"

it "should call 'bar' with appropriate arguments" do
  expect(subject).to receive(:bar).with("an argument I want")
  subject.foo
end

Is this what you're after?
