I had the same problem with a Google Docs URL. Enclosing the URL in quotes did the trick for me:

wget "https://docs.google.com/spreadsheets/export?format=tsv&id=1sSi9f6m-zKteoXA4r4Yq-zfdmL4rjlZRt38mejpdhC23" -O sheet.tsv

My company does the same thing for a number of customers where we host a web site for them although in our case it's xyz.company.com rather than www.company.com. We do get them to set the A record on xyz.company.com to point to an IP address we allocate them.

As to how you could cope with a change in IP address I don't think there is a perfect solution. Some ideas are:

• Use a NAT or IP load balancer and give your customers an IP address belonging to it. If the IP address of the web server needs to change you could make an update on the NAT or load balancer,

• Offer a DNS hosting service as well and get your customers to host their domain with you so that you'd be in a position to update the A records,

• Get your customers to set their A record up to one main web server and use a HTTP redirect for each customer's web requests.

A much simpler solution, without all the inside form-group elements

<div class="form-group">
       <label for="birthday" class="col-xs-2 control-label">Birthday</label>
       <div class="col-xs-10">
           <div class="form-inline">
               <input type="text" class="form-control" placeholder="year" style="width:70px;"/>
               <input type="text" class="form-control" placeholder="month" style="width:80px;"/>
               <input type="text" class="form-control" placeholder="day" style="width:100px;"/>                        
           </div>
     </div>
</div>

... and it will look like this,

Cheers!

Remove VALUES from your SQL.

Go in the Gradle Scripts -> local.properties and paste this

`org.gradle.jvmargs=-XX\:MaxHeapSize\=512m -Xmx512m`

, if you want to change it to 512. Hope it works !

-D, --dump-header <file>
       Write the protocol headers to the specified file.

       This  option  is handy to use when you want to store the headers
       that a HTTP site sends to you. Cookies from  the  headers  could
       then  be  read  in  a  second  curl  invocation by using the -b,
       --cookie option! The -c, --cookie-jar option is however a better
       way to store cookies.

and

-S, --show-error
       When used with -s, --silent, it makes curl show an error message if it fails.

and

-L/--location
      (HTTP/HTTPS) If the server reports that the requested page has moved to a different location (indicated with a Location: header and a 3XX response
      code), this option will make curl redo the request on the new place. If used together with -i/--include or -I/--head, headers from  all  requested
      pages  will  be  shown.  When authentication is used, curl only sends its credentials to the initial host. If a redirect takes curl to a different
      host, it won’t be able to intercept the user+password. See also --location-trusted on how to change this. You can limit the amount of redirects to
      follow by using the --max-redirs option.

      When curl follows a redirect and the request is not a plain GET (for example POST or PUT), it will do the following request with a GET if the HTTP
      response was 301, 302, or 303. If the response code was any other 3xx code, curl will re-send the following  request  using  the  same  unmodified
      method.

from the man page. so

curl -sSL -D - www.acooke.org -o /dev/null

follows redirects, dumps the headers to stdout and sends the data to /dev/null (that's a GET, not a POST, but you can do the same thing with a POST - just add whatever option you're already using for POSTing data)

note the - after the -D which indicates that the output "file" is stdout.

Actually jessehouwing gave the solution for normal scenario.

But in my case I have enabled 2 types of session in my web.config file

It's like below.

First one :

<modules runAllManagedModulesForAllRequests="true">
        <remove name="Session" />
        <add name="Session" type="System.Web.SessionState.SessionStateModule, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</modules>

Second one :

<sessionState mode="Custom" customProvider="DefaultSessionProvider">
            <providers>
                <add name="DefaultSessionProvider" type="System.Web.Providers.DefaultSessionStateProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" connectionStringName="PawLoyalty" applicationName="PawLoyalty"/>
            </providers>
 </sessionState>

So in my case I have to comment Second one.B'cos that thing for the production.When I commented out second one my problem vanished.

_{*  “Jan Zero, 1900” is 1899/12/31; see the Bug section below. † Excel 2011 for Mac (and older) use the 1904 date system.}

As I often use awk to process CSV and space-delimited content, I developed a way to convert UNIX epoch to timezone/DST-appropriate Excel date format:

echo 1234567890 |awk '{ 
  # tries GNU date, tries BSD date on failure
  cmd = sprintf("date -d@%d +%%z 2>/dev/null || date -jf %%s %d +%%z", $1, $1)
  cmd |getline tz                                # read in time-specific offset
  hours = substr(tz, 2, 2) + substr(tz, 4) / 60  # hours + minutes (hi, India)
  if (tz ~ /^-/) hours *= -1                     # offset direction (east/west)
  excel = $1/86400 + hours/24 + 25569            # as days, plus offset
  printf "%.9f\n", excel
}'

I used echo for this example, but you can pipe a file where the first column (for the first cell in .csv format, call it as awk -F,) is a UNIX epoch. Alter $1 to represent your desired column/cell number or use a variable instead.

This makes a system call to date. If you will reliably have the GNU version, you can remove the 2>/dev/null || date … +%%z and the second , $1. Given how common GNU is, I wouldn't recommend assuming BSD's version.

The getline reads the time zone offset outputted by date +%z into tz, which is then translated into hours. The format will be like -0700 (PDT) or +0530 (IST), so the first substring extracted is 07 or 05, the second is 00 or 30 (then divided by 60 to be expressed in hours), and the third use of tz sees whether our offset is negative and alters hours if needed.

The formula given in all of the other answers on this page is used to set excel, with the addition of the daylight-savings-aware time zone adjustment as hours/24.

If you're on an older version of Excel for Mac, you'll need to use 24107 in place of 25569 (see the mapping above).

To convert any arbitrary non-epoch time to Excel-friendly times with GNU date:

echo "last thursday" |awk '{ 
  cmd = sprintf("date -d \"%s\" +\"%%s %%z\"", $0)
  cmd |getline
  hours = substr($2, 2, 2) + substr($2, 4) / 60
  if ($2 ~ /^-/) hours *= -1
  excel = $1/86400 + hours/24 + 25569
  printf "%.9f\n", excel
}'

This is basically the same code, but the date -d no longer has an @ to represent unix epoch (given how capable the string parser is, I'm actually surprised the @ is mandatory; what other date format has 9-10 digits?) and it's now asked for two outputs: the epoch and the time zone offset. You could therefore use e.g. @1234567890 as an input.

Bug

Lotus 1-2-3 (the original spreadsheet software) intentionally treated 1900 as a leap year despite the fact that it was not (this reduced the codebase at a time when every byte counted). Microsoft Excel retained this bug for compatibility, skipping day 60 (the fictitious 1900/02/29), retaining Lotus 1-2-3's mapping of day 59 to 1900/02/28. LibreOffice instead assigned day 60 to 1900/02/28 and pushed all previous days back one.

Any date before 1900/03/01 could be as much as a day off:

Day        Excel   LibreOffice
-1            -1    1899/12/29
 0    1900/01/00*   1899/12/30
 1    1900/01/01    1899/12/31
 2    1900/01/02    1900/01/01
 …
59    1900/02/28    1900/02/27
60    1900/02/29(!) 1900/02/28
61    1900/03/01    1900/03/01

Excel doesn't acknowledge negative dates and has a special definition of the Zeroth of January (1899/12/31) for day zero. Internally, Excel does indeed handle negative dates (they're just numbers after all), but it displays them as numbers since it doesn't know how to display them as dates (nor can it convert older dates into negative numbers). Feb 29 1900, a day that never happened, is recognized by Excel but not LibreOffice.

Simply updated Xcode. Solved my problem

A simpler way is

ggplot(data=df, aes(x=xvar, y=yvar)) + 
geom_point()

ggsave(path = path, width = width, height = height, device='tiff', dpi=700)

Handles either type of line break

str.replace(new RegExp('\r?\n','g'), '<br />');

Use BufferedReader and InputStreamReader classes.

BufferedReader buffer=new BufferedReader(new InputStreamReader(System.in));
String line=buffer.readLine();

Or use java.util.Scanner class methods.

Scanner scan=new Scanner(System.in);

The simple answer is to shoot your call off to an external scrip via AJAX request. Then handle the response how you like.

There was an error in understanding of return Type Just add Header and it will solve your problem

@Headers("Content-Type: application/json")

$ g=3
$ c=133
$ ([ "$g$c" = "1123" ] || [ "$g$c" = "2456" ]) && echo "abc" || echo "efg"
efg
$ g=1
$ c=123
$ ([ "$g$c" = "1123" ] || [ "$g$c" = "2456" ]) && echo "abc" || echo "efg"
abc

Sounds like you don't want to resolve dns yourself (this might be the wrong nomenclature) dnspython appears to be a standalone dns client that will understandably ignore your operating system because its bypassing the operating system's utillities.

We can look at a shell utility named getent to understand how the (debian 11 alike) operating system resolves dns for programs, this is likely the standard for all *nix like systems that use a socket implementation.

see man getent's "hosts" section, which mentions the use of getaddrinfo, which we can see as man getaddrinfo

and to use it in python, we have to extract some info from the data structures

.

import socket

def get_ipv4_by_hostname(hostname):
    # see `man getent` `/ hosts `
    # see `man getaddrinfo`

    return list(
        i        # raw socket structure
            [4]  # internet protocol info
            [0]  # address
        for i in 
        socket.getaddrinfo(
            hostname,
            0  # port, required
        )
        if i[0] is socket.AddressFamily.AF_INET  # ipv4

        # ignore duplicate addresses with other socket types
        and i[1] is socket.SocketKind.SOCK_RAW  
    )

print(get_ipv4_by_hostname('localhost'))
print(get_ipv4_by_hostname('google.com'))

As others pointed out, the only difference is that require throws a fatal error, and include - a catchable warning. As for which one to use, my advice is to stick to include. Why? because you can catch a warning and produce a meaningful feedback to end users. Consider

  // Example 1.
  // users see a standard php error message or a blank screen
  // depending on your display_errors setting
  require 'not_there'; 


  // Example 2.
  // users see a meaningful error message
  try {
      include 'not_there';
  } catch(Exception $e) {
     echo "something strange happened!";
  }

NB: for example 2 to work you need to install an errors-to-exceptions handler, as described here http://www.php.net/manual/en/class.errorexception.php

  function exception_error_handler($errno, $errstr, $errfile, $errline ) {
     throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
  }
  set_error_handler("exception_error_handler");   

A char value in C is implicitly convertible to an int. e.g, char c; ... printf("%d", c) prints the decimal ASCII value of c, and int i = c; puts the ASCII integer value of c in i. You can also explicitly convert it with (int)c. If you mean something else, such as how to convert an ASCII digit to an int, that would be c - '0', which implicitly converts c to an int and then subtracts the ASCII value of '0', namely 48 (in C, character constants such as '0' are of type int, not char, for historical reasons).

You can find excellent information at http://javarevisited.blogspot.com/2011/02/how-hashmap-works-in-java.html

To Summarize:

HashMap works on the principle of hashing

put(key, value): HashMap stores both key and value object as Map.Entry. Hashmap applies hashcode(key) to get the bucket. if there is collision ,HashMap uses LinkedList to store object.

get(key): HashMap uses Key Object's hashcode to find out bucket location and then call keys.equals() method to identify correct node in LinkedList and return associated value object for that key in Java HashMap.

As far as I know, and I cant verify it now, you cannot stop remote services with the Stop-Service cmdlet or with .Net, it is not supported.

Yes it works, but it stopes the service on your local machine, not on the remote computer.

Now, if the above is correct, without remoting or wmi enabled, you could set a scheduled job on the remote system, using AT, that runs Stop-Service locally.

Too late to join the party but may be it can help someone:

We can do it in two step, first filter by first property and then concatenate by second filter:

$scope.filterd = $filter('filter')($scope.empList, { dept: "account" });
$scope.filterd = $scope.filterd.concat($filter('filter')($scope.empList, { dept: "sales" }));  

See the working fiddle with multiple property filter

Add android.permission.READ_EXTERNAL_STORAGE in manifest, worked for me

array_shift the only parameter is an array passed by reference. The return value of explode(".", $value) does not have any reference. Hence the error.

You should store the return value to a variable first.

    $arr = explode(".", $value);
    $extension = strtolower(array_pop($arr));   
    $fileName = array_shift($arr);

From PHP.net

The following things can be passed by reference:

- Variables, i.e. foo($a)
- New statements, i.e. foo(new foobar())
- [References returned from functions][2]

No other expressions should be passed by reference, as the result is undefined. For example, the following examples of passing by reference are invalid:

In the first place, you should note that PDF and HTML and different formats that hardly have anything in common. If TCPDF allows you to provide input data using HTML and CSS it's because it implements a simple parser for these two languages and tries to figure out how to translate that into PDF. So it's logical that TCPDF only supports a little subset of the HTML and CSS specification and, even in supported stuff, it's probably not as perfect as in first class web browsers.

Said that, the question is: what's supported and what's not? The documentation basically skips the issue and let's you enjoy the trial and error method.

Having a look at the source code, we can see there's a protected method called TCPDF::getHtmlDomArray() that, among other things, parses CSS declarations. I can see stuff like font-family, list-style-type or text-indent but there's no margin or padding as far as I can see and, definitively, there's no float at all.

To sum up: with TCPDF, you can use CSS for some basic formatting. If you need to convert from HTML to PDF, it's the wrong tool. (If that's the case, may I suggest wkhtmltopdf?)

You can't upload files via ajax, you need to use an iFrame or some other trickery to do a full postback. This is mainly due to security concerns.

Here's a decent write-up including a sample project using SWFUpload and ASP.Net MVC by Steve Sanderson. It's the first thing I read getting this working properly with Asp.Net MVC (I was new to MVC at the time as well), hopefully it's as helpful for you.

That doesn't look like a very Angular way of doing it. I'm not entirely sure why it doesn't work, but you'd probably need to access the scope in order to use a function like that.

My suggestion would be to create a filter. That's the Angular way.

myModule.filter('ceil', function() {
    return function(input) {
        return Math.ceil(input);
    };
});

Then in your HTML do this:

<p>The percentage is {{ (100*count/total) | ceil }}%</p>

You want to see if they contain the same elements, but don't care about the order.

You can use a set:

>>> set(['one', 'two', 'three']) == set(['two', 'one', 'three'])
True

But the set object itself will only contain one instance of each unique value, and will not preserve order.

>>> set(['one', 'one', 'one']) == set(['one'])
True

So, if tracking duplicates/length is important, you probably want to also check the length:

def are_eq(a, b):
    return set(a) == set(b) and len(a) == len(b)

As pointed out in a few other answers, you can iterate over all elements in a matrix A (of any dimension) using a linear index from 1 to numel(A) in a single for loop. There are also a couple of functions you can use: arrayfun and cellfun.

Let's first assume you have a function that you want to apply to each element of A (called my_func). You first create a function handle to this function:

fcn = @my_func;

If A is a matrix (of type double, single, etc.) of arbitrary dimension, you can use arrayfun to apply my_func to each element:

outArgs = arrayfun(fcn, A);

If A is a cell array of arbitrary dimension, you can use cellfun to apply my_func to each cell:

outArgs = cellfun(fcn, A);

The function my_func has to accept A as an input. If there are any outputs from my_func, these are placed in outArgs, which will be the same size/dimension as A.

One caveat on outputs... if my_func returns outputs of different sizes and types when it operates on different elements of A, then outArgs will have to be made into a cell array. This is done by calling either arrayfun or cellfun with an additional parameter/value pair:

outArgs = arrayfun(fcn, A, 'UniformOutput', false);
outArgs = cellfun(fcn, A, 'UniformOutput', false);

If you are looking for a real simple way to log, you can use this one liner. If the file doesn't exist, it's created.

System.IO.File.AppendAllText(@"c:\log.txt", "mymsg\n");

I see that all the answers provided are correct. However, one important detail was overlooked: The size of the image MUST be at least 200 X 200 px, otherwise Facebook will substitute the thumbnail with the first available image that meets the criteria on the page. Another fact is that the minimum required is to include the 3 metas that Facebook requires for the og:image to take effect:

<meta property="og:title" content="Title of the page" />
<!-- NEXT LINE Even if page is dynamically generated and URL contains query parameters -->
<meta property="og:url" content="http://yoursite.com" />
<meta property="og:image" content="http://convertaholics.com/convertaholics-og.png" />

How Add new record ,Update record,Delete Records using Vb.net Forms when Access as a back

The constructor of your A object allocates another object dynamically and stores a pointer to that dynamically allocated object in a raw pointer.

For that scenario, you must define your own copy constructor , assignment operator and destructor. The compiler generated ones will not work correctly. (This is a corollary to the "Law of the Big Three": A class with any of destructor, assignment operator, copy constructor generally needs all 3).

You have defined your own destructor (and you mentioned creating a copy constructor), but you need to define both of the other 2 of the big three.

An alternative is to store the pointer to your dynamically allocated int[] in some other object that will take care of these things for you. Something like a vector<int> (as you mentioned) or a boost::shared_array<>.

To boil this down - to take advantage of RAII to the full extent, you should avoid dealing with raw pointers to the extent possible.

And since you asked for other style critiques, a minor one is that when you are deleting raw pointers you do not need to check for 0 before calling delete - delete handles that case by doing nothing so you don't have to clutter you code with the checks.

$('#myId').val() should do it, failing that I would try:

$('#myId option:selected').val()

If you're only getting these to manually pass into df.set_index(), that's unnecessary. Just directly do df.set_index['your_col_name', drop=False], already.

It's very rare in pandas that you need to get an index as a Python list (unless you're doing something pretty funky, or else passing them back to NumPy), so if you're doing this a lot, it's a code smell that you're doing something wrong.

• For your cookies, see this answer.
• For PHP's own session cookie (PHPSESSID, by default), see @richie's answer

The setcookie() and setrawcookie() functions, introduced the httponly parameter, back in the dark ages of PHP 5.2.0, making this nice and easy. Simply set the 7th parameter to true, as per the syntax

Function syntax simplified for brevity

setcookie(    $name, $value, $expire, $path, $domain, $secure, $httponly )
setrawcookie( $name, $value, $expire, $path, $domain, $secure, $httponly )

In PHP < 8, specify NULL for parameters you wish to remain as default.

In PHP >= 8 you can benefit from using named parameters. See this question about named params.

setcookie( $name, $value, httponly:true )

It is also possible using the older, lower-level header() function:

header( "Set-Cookie: name=value; httpOnly" );

You may also want to consider if you should be setting the secure parameter.

Curent class .dropdown-submenu > .dropdown-menu have left: 100%;. So, if you want to open submenu on the left side, override those settings to negative left position. For example left: -95%;. Now you will get submenu on the left side, and you can tweak other settings to get perfect preview.

Here is DEMO

EDIT: OP's question and my answer are from august 2012. Meanwhile, Bootstrap changed, so now you have .pull-left class. Back then, my answer was correct. Now you don't have to manually set css, you have that .pull-left class.

EDIT 2: Demos aren't working, because Bootstrap changed their URL's. Just change external resources in jsfiddle and replace them with new ones.

It is today possible to configure Safari to access local files.

• By default Safari doesn't allow access to local files.
• To enable this option: First you need to enable the develop menu.
• Click on the Develop menu Select Disable Local File Restrictions.

Source: http://ccm.net/faq/36342-safari-how-to-enable-local-file-access

why reinvent the wheel? use microsoft's json serialize or a 3rd party library such as json.NET

If you are using XAMPP on Mac, this worked for me:

Moving the CSV/TXT file to /Applications/XAMPP/xamppfiles/htdocs/ as following

LOAD DATA LOCAL INFILE '/Applications/XAMPP/xamppfiles/htdocs/file.csv' INTO TABLE `tablename` FIELDS TERMINATED BY ',' LINES TERMINATED BY ';'

Here's a wrapped up example using the sed approach from this answer:

$ cat /path/to/some/file | prefix_lines "WOW: "

WOW: some text
WOW: another line
WOW: more text

prefix_lines

function show_help()
{
  IT=$(CAT <<EOF
    Usage: PREFIX {FILE}

    e.g.

    cat /path/to/file | prefix_lines "WOW: "

      WOW: some text
      WOW: another line
      WOW: more text
  )
  echo "$IT"
  exit
}

# Require a prefix
if [ -z "$1" ]
then
  show_help
fi

# Check if input is from stdin or a file
FILE=$2
if [ -z "$2" ]
then
  # If no stdin exists
  if [ -t 0 ]; then
    show_help
  fi
  FILE=/dev/stdin
fi

# Now prefix the output
PREFIX=$1
sed -e "s/^/$PREFIX/" $FILE

why not simply just give the input field where you want to jump to a id and do a simple focus

$("#newListField").focus();

Mota's answer is great unless your BufferedImage came from a Monochrome Bitmap. A Monochrome Bitmap has only 2 possible values for its pixels (for example 0 = black and 1 = white). When a Monochrome Bitmap is used then the

final byte[] pixels = ((DataBufferByte) image.getRaster().getDataBuffer()).getData();

call returns the raw Pixel Array data in such a fashion that each byte contains more than one pixel.

So when you use a Monochrome Bitmap image to create your BufferedImage object then this is the algorithm you want to use:

/**
 * This returns a true bitmap where each element in the grid is either a 0
 * or a 1. A 1 means the pixel is white and a 0 means the pixel is black.
 * 
 * If the incoming image doesn't have any pixels in it then this method
 * returns null;
 * 
 * @param image
 * @return
 */
public static int[][] convertToArray(BufferedImage image)
{

    if (image == null || image.getWidth() == 0 || image.getHeight() == 0)
        return null;

    // This returns bytes of data starting from the top left of the bitmap
    // image and goes down.
    // Top to bottom. Left to right.
    final byte[] pixels = ((DataBufferByte) image.getRaster()
            .getDataBuffer()).getData();

    final int width = image.getWidth();
    final int height = image.getHeight();

    int[][] result = new int[height][width];

    boolean done = false;
    boolean alreadyWentToNextByte = false;
    int byteIndex = 0;
    int row = 0;
    int col = 0;
    int numBits = 0;
    byte currentByte = pixels[byteIndex];
    while (!done)
    {
        alreadyWentToNextByte = false;

        result[row][col] = (currentByte & 0x80) >> 7;
        currentByte = (byte) (((int) currentByte) << 1);
        numBits++;

        if ((row == height - 1) && (col == width - 1))
        {
            done = true;
        }
        else
        {
            col++;

            if (numBits == 8)
            {
                currentByte = pixels[++byteIndex];
                numBits = 0;
                alreadyWentToNextByte = true;
            }

            if (col == width)
            {
                row++;
                col = 0;

                if (!alreadyWentToNextByte)
                {
                    currentByte = pixels[++byteIndex];
                    numBits = 0;
                }
            }
        }
    }

    return result;
}

As already explained by the other contributers, you could print out the counter and then replace the return with a break statement.

N = int(input("enter a positive integer:"))
counter = 1
while (N > 0):
    counter = counter * N
    N = N - 1
    print(counter)
    break

If you don't like to see a lot of

find: `./.svn': No such file or directory

warnings, then use the -depth switch:

find . -depth -name .svn -exec rm -fr {} \;

exec 'print "hello";' * 2

should work, but I'm kind of ashamed that I thought of it.

Update: Just thought of another one:

for _ in " "*10: print "hello"

You already have a version of mySQL installed on this machine that is using port 3306. Go into the most recent my.ini file and change the port to 3307. Restart the mySQL service and see if it comes up.

You also need to change port 3306 to 3307 in xampp\php\php.ini

The solution is very simple:

1- Copy your git path. forexample : http://github.com/yourname/my-git-project.git

2- Open notepad and Paste it. Then copy the path from notepad.

3- paste the path to command line

thats it.

To complement Jakub's answer, if you have access to the remote git server in ssh, you can go into the git remote directory and set:

user@remote$ git config receive.denyNonFastforwards false

Then go back to your local repo, try again to do your commit with --force:

user@local$ git push origin +master:master --force

And finally revert the server's setting in the original protected state:

user@remote$ git config receive.denyNonFastforwards true

With C++11 for measuring the execution time of a piece of code, we can use the now() function:

auto start = chrono::steady_clock::now();

//  Insert the code that will be timed

auto end = chrono::steady_clock::now();

// Store the time difference between start and end
auto diff = end - start;

If you want to print the time difference between start and end in the above code, you could use:

cout << chrono::duration <double, milli> (diff).count() << " ms" << endl;

If you prefer to use nanoseconds, you will use:

cout << chrono::duration <double, nano> (diff).count() << " ns" << endl;

The value of the diff variable can be also truncated to an integer value, for example, if you want the result expressed as:

diff_sec = chrono::duration_cast<chrono::nanoseconds>(diff);
cout << diff_sec.count() << endl;

For more info click here

var result = string.Join("", input.Select(c => ((int)c).ToString("X2")));

OR

var result  =string.Join("", 
                input.Select(c=> String.Format("{0:X2}", Convert.ToInt32(c))));

To call a sub inside another sub you only need to do:

Call Subname()

So where you have CalculateA(Nc,kij, xi, a1, a) you need to have call CalculateA(Nc,kij, xi, a1, a)

As the which runs first problem it's for you to decide, when you want to run a sub you can go to the macro list select the one you want to run and run it, you can also give it a key shortcut, therefore you will only have to press those keys to run it. Although, on secondary subs, I usually do it as Private sub CalculateA(...) cause this way it does not appear in the macro list and it's easier to work

Hope it helps, Bruno

PS: If you have any other question just ask, but this isn't a community where you ask for code, you come here with a question or a code that isn't running and ask for help, not like you did "It would be great if you could write it in the Excel VBA format."

For my case, I had to right click the solution and click "Retarget Projects". In my case I retargetted to Windows SDK version 10.0.1777.0 and Platform Toolset v142. I also had to change "Windows.h"to<windows.h>

I am running Visual Studio 2019 version 16.25 on a windows 10 machine

int i = c - '0';

You should be aware that this doesn't perform any validation against the character - for example, if the character was 'a' then you would get 91 - 48 = 49. Especially if you are dealing with user or network input, you should probably perform validation to avoid bad behavior in your program. Just check the range:

if ('0' <= c &&  c <= '9') {
    i = c - '0';
} else {
    /* handle error */
}

Note that if you want your conversion to handle hex digits you can check the range and perform the appropriate calculation.

if ('0' <= c && c <= '9') {
    i = c - '0';
} else if ('a' <= c && c <= 'f') {
    i = 10 + c - 'a';
} else if ('A' <= c && c <= 'F') {
    i = 10 + c - 'A';
} else {
    /* handle error */
}

That will convert a single hex character, upper or lowercase independent, into an integer.

A call to Class#getResourceAsStream(String) delegates to the class loader and the resource is searched in the class path. In other words, you current code won't work and you should put abc.txt in WEB-INF/classes, or in WEB-INF/lib if packaged in a jar file.

Or use ServletContext.getResourceAsStream(String) which allows servlet containers to make a resource available to a servlet from any location, without using a class loader. So use this from a Servlet:

this.getServletContext().getResourceAsStream("/WEB-INF/abc.txt") ;

But is there a way I can call getServletContext from my Web Service?

If you are using JAX-WS, then you can get a WebServiceContext injected:

@Resource
private WebServiceContext wsContext;

And then get the ServletContext from it:

ServletContext sContext= wsContext.getMessageContext()
                             .get(MessageContext.SERVLET_CONTEXT));

This is more a workaround than a real solution. You can create a new object test_data with another column name:

left_join("names<-"(test_data, "name"), kantrowitz, by = "name")

     name gender
1    john      M
2    bill either
3 madison      M
4    abby either
5     zzz   <NA>

This could also occur if you refer to a variable in the data.frame that doesn't exist. For example, recently I forgot to tell ddply to summarize by one of my variables that I used in geom_line to specify line color. Then, ggplot didn't know where to find the variable I hadn't created in the summary table, and I got this error.

Here's my helper class using Jon Skeet's implementation.

public static class HashCode
{
    public const int Start = 17;

    public static int Hash<T>(this int hash, T obj)
    {
        var h = EqualityComparer<T>.Default.GetHashCode(obj);
        return unchecked((hash * 31) + h);
    }
}

Usage:

public override int GetHashCode()
{
    return HashCode.Start
        .Hash(_field1)
        .Hash(_field2)
        .Hash(_field3);
}

If you want to avoid writing an extension method for System.Int32:

public readonly struct HashCode
{
    private readonly int _value;

    public HashCode(int value) => _value = value;

    public static HashCode Start { get; } = new HashCode(17);

    public static implicit operator int(HashCode hash) => hash._value;

    public HashCode Hash<T>(T obj)
    {
        var h = EqualityComparer<T>.Default.GetHashCode(obj);
        return unchecked(new HashCode((_value * 31) + h));
    }

    public override int GetHashCode() => _value;
}

It still avoids any heap allocation and is used exactly the same way:

public override int GetHashCode()
{
    // This time `HashCode.Start` is not an `Int32`, it's a `HashCode` instance.
    // And the result is implicitly converted to `Int32`.
    return HashCode.Start
        .Hash(_field1)
        .Hash(_field2)     
        .Hash(_field3);
}

Edit (May 2018): EqualityComparer<T>.Default getter is now a JIT intrinsic - the pull request is mentioned by Stephen Toub in this blog post.

If push request is shows Rejected, then try first pull from your github account and then try push.

Ex:

In my case it was giving an error-

 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'https://github.com/ashif8984/git-github.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

****So what I did was-****

$ git pull
$ git push

And the code was pushed successfully into my Github Account.

Just an additional note about reflection: I have observed in some special cases, when several classes with the same name exist in different packages, that reflection as used in the top answer may fail to pick the correct class from the object. So if you know what is the package.class of the object, then it's better to access its private field values as follows:

org.deeplearning4j.nn.layers.BaseOutputLayer ll = (org.deeplearning4j.nn.layers.BaseOutputLayer) model.getLayer(0);
Field f = Class.forName("org.deeplearning4j.nn.layers.BaseOutputLayer").getDeclaredField("solver");
f.setAccessible(true);
Solver s = (Solver) f.get(ll);

(This is the example class that was not working for me)

ES6:

let after = 'something after';
let text = `before text ${after}`;

I also had this issue. My solution is remove file Gemfile.lock, and install gems again: bundle install

Try to use the following strategies in order to improve your app performance:

• Use multi-threading programming if possible. The performance benefits are huge, even if your smart phone has one core (threads can run in different cores, if the processor has two or more). It's useful to make your app logic separated from the UI. Use Java threads, AsyncTask or IntentService. Check this.
• Read and follow the misc performance tips of Android development website. Check here.

$("#checkAll").change(function () {
    $("input:checkbox.cb-element").prop('checked', $(this).prop("checked"));
});
$(".cb-element").change(function () {
        _tot = $(".cb-element").length                        
        _tot_checked = $(".cb-element:checked").length;

        if(_tot != _tot_checked){
            $("#checkAll").prop('checked',false);
        }

Something similar to the proposed solutions, only the result is json with column_header : vaule for db_query ie sql.

cur = conn.cursor()
cur.execute(sql)
res = [dict((cur.description[i][0], value) for i, value in enumerate(row)) for row in cur.fetchall()]

output json example:

[
   {
      "FIRST_ROW":"Test 11",
      "SECOND_ROW":"Test 12",
      "THIRD_ROW":"Test 13"
   },
   {
      "FIRST_ROW":"Test 21",
      "SECOND_ROW":"Test 22",
      "THIRD_ROW":"Test 23"
   }
]

I have the feeling that the check should be different

new: h < 768 || w < 1024

You can also run conda init as below,

C:\ProgramData\Anaconda3\Scripts\conda init cmd.exe

or

C:\ProgramData\Anaconda3\Scripts\conda init powershell

Note that the execution policy of powershell must be set, e.g. using Set-ExecutionPolicy Unrestricted.

As an additional note, you may also add markup language for pausing or waiting, I learned this from the iPhone iOS which allows numbers to be stored with extension numbers in the same line. A semi-colon establishes a wait, which will show as a next step upon calling the number. This helps to simplify the workflow of calling numbers with extensions in their board. You press the button shown on the bottom left of the iPhone screen when prompted, and the iPhone will dial it automatically.

<a href="tel:+50225079227;1">Call Now</a>

The pause is entered with a comma ",", allowing a short pause of time for each comma. Once the time has passed, the number after the comma will be dialed automatically

<a href="tel:+50225079227,1">Call Now, you will be automaticlaly transferred</a>

For Windows users: You can do as RTA said or through command line do this: Navigate to the locaiton of the eclipse executable then run:

 eclipse.lnk -clean

First check the name of your executable using the command 'dir' on its path

I give here 2 ways of coping array, for C and C++ language. memcpy and copy both ar usable on C++ but copy is not usable for C, you have to use memcpy if you are trying to copy array in C.

#include <stdio.h>
#include <iostream>
#include <algorithm> // for using copy (library function)
#include <string.h> // for using memcpy (library function)


int main(){

    int arr[] = {1, 1, 2, 2, 3, 3};
    int brr[100];

    int len = sizeof(arr)/sizeof(*arr); // finding size of arr (array)

    std:: copy(arr, arr+len, brr); // which will work on C++ only (you have to use #include <algorithm>
    memcpy(brr, arr, len*(sizeof(int))); // which will work on both C and C++

    for(int i=0; i<len; i++){ // Printing brr (array).
        std:: cout << brr[i] << " ";
    }

    return 0;
}

Two main purposes for error handling:

1. Trap errors you can predict but can't control the user from doing (e.g. saving a file to a thumb drive when the thumb drives has been removed)
2. For unexpected errors, present user with a form that informs them what the problem is. That way, they can relay that message to you and you might be able to give them a work-around while you work on a fix.

So, how would you do this?

First of all, create an error form to display when an unexpected error occurs.

It could look something like this (FYI: Mine is called frmErrors):

Notice the following labels:

• lblHeadline
• lblSource
• lblProblem
• lblResponse

Also, the standard command buttons:

• Ignore
• Retry
• Cancel

There's nothing spectacular in the code for this form:

Option Explicit

Private Sub cmdCancel_Click()
  Me.Tag = CMD_CANCEL
  Me.Hide
End Sub

Private Sub cmdIgnore_Click()
  Me.Tag = CMD_IGNORE
  Me.Hide
End Sub

Private Sub cmdRetry_Click()
  Me.Tag = CMD_RETRY
  Me.Hide
End Sub

Private Sub UserForm_Initialize()
  Me.lblErrorTitle.Caption = "Custom Error Title Caption String"
End Sub

Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
  'Prevent user from closing with the Close box in the title bar.
    If CloseMode <> 1 Then
      cmdCancel_Click
    End If
End Sub

Basically, you want to know which button the user pressed when the form closes.

Next, create an Error Handler Module that will be used throughout your VBA app:

You may have errors that will be custom only to your application. This would typically be a short list of errors specifically only to your application. If you don't already have a constants module, create one that will contain an ENUM of your custom errors. (NOTE: Office '97 does NOT support ENUMS.). The ENUM should look something like this:

Public Enum CustomErrorName
  MaskedFilterNotSupported
  InvalidMonthNumber
End Enum

Create a module that will throw your custom errors.

Just came here to share what was happening to me.
You don't need to specify the parent, states work in an document oriented way so, instead of specifying parent: app, you could just change the state to app.index

.config(function($stateProvider, $urlRouterProvider){
    $urlRouterProvider.otherwise("/index.html");

$stateProvider.state('app', {
  abstract: true,
  templateUrl: "tpl.menu.html"
});

$stateProvider.state('app.index', {
    url: '/',
    templateUrl: "tpl.index.html"
});

$stateProvider.state('app.register', {
    url: "/register",
    templateUrl: "tpl.register.html"
});

EDIT Warning, if you want to go deep in the nesting, the full path must me specified. For example, you can't have a state like

app.cruds.posts.create

without having a

app
app.cruds
app.cruds.posts

or angular will throw an exception saying it can't figure out the rout. To solve that you can define abstract states

.state('app', {
     url: "/app",
     abstract: true
})
.state('app.cruds', {
     url: "/app/cruds",
     abstract: true
})
.state('app/cruds/posts', {
     url: "/app/cruds/posts",
     abstract: true
})

The !== opererator tests whether values are not equal or not the same type. i.e.

var x = 5;
var y = '5';
var 1 = y !== x; // true
var 2 = y != x; // false

If you use Django, it has a built in @classproperty decorator.

You are going to need to call the SmsManager class. You are probably going to need to use the STATUS_ON_ICC_READ constant and maybe put what you get there into your apps local db so that you can keep track of what you have already read vs the new stuff for your app to parse through. BUT bear in mind that you have to declare the use of the class in your manifest, so users will see that you have access to their SMS called out in the permissions dialogue they get when they install. Seeing SMS access is unusual and could put some users off. Good luck.

Here is the link that goes into depth on the Sms Manager

Boolean wrapper is useful when you want to whether value was assigned or not apart from true and false. It has the following three states:

• True
• False
• Not defined which is null

Whereas boolean has only two states:

• True
• False

The above difference will make it helpful in Lists of Boolean values, which can have True, False or Null.

To get your radio button to list horizontally , just add

RepeatDirection="Horizontal"

to your .aspx file where the asp:radiobuttonlist is being declared.

The basic syntax for using ternary operator is like this:

(condition) ? (if_true) : (if_false)

For you case it is like this:

number < 0 ? bigInt.sign = 0 : bigInt.sign = 1;

There are 2 options to find matching text; string.match or string.find.

Both of these perform a regex search on the string to find matches.

string.find()

string.find(subject string, pattern string, optional start position, optional plain flag)

Returns the startIndex & endIndex of the substring found.

The plain flag allows for the pattern to be ignored and intead be interpreted as a literal. Rather than (tiger) being interpreted as a regex capture group matching for tiger, it instead looks for (tiger) within a string.

Going the other way, if you want to regex match but still want literal special characters (such as .()[]+- etc.), you can escape them with a percentage; %(tiger%).

You will likely use this in combination with string.sub

Example

str = "This is some text containing the word tiger."
if string.find(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

string.match()

string.match(s, pattern, optional index)

Returns the capture groups found.

Example

str = "This is some text containing the word tiger."
if string.match(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

The List interface already has this solved.

int temp = 2;
if(bankAccNos.contains(bakAccNo)) temp=1;

More can be found in the documentation about List.

What do you mean by a long date type?

You can cast a long to a double:

double d = (double) 15552451L;

Range("A1").value = Environ("Username")

This is better than Application.Username, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.

• Application Username is the name of the User set in Excel > Tools > Options
• Environ("Username") is the name you registered for Windows; see Control Panel >System

To conditionally control view of Template/Command fields, use RowDataBound event of Gridview, like:

    <asp:GridView ID="gv1" OnRowDataBound="gv1_RowDataBound"
              runat="server" AutoGenerateColumns="False" DataKeyNames="Id" >
    <Columns>   
        ...        
           <asp:TemplateField HeaderText="Order Status" 
HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center"> 
                 <ItemTemplate> 
                       <asp:Label ID="lblOrderStatus" runat="server"
Text='<%# Bind("OrderStatus") %>'></asp:Label> 
                 </ItemTemplate>
                 <HeaderStyle HorizontalAlign="Center"></HeaderStyle>
                 <ItemStyle HorizontalAlign="Center"></ItemStyle>
           </asp:TemplateField>  
        ...

            <asp:CommandField ShowSelectButton="True" SelectText="Select" />

    </Columns>
                </asp:GridView>

and following:

protected void gv1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        Label lblOrderStatus=(Label) e.Row.Cells[4].FindControl("lblOrderStatus");

        if (lblOrderStatus.Text== "Ordered")
        {
            lblOrderStatus.ForeColor = System.Drawing.Color.DarkBlue;
            LinkButton bt = (LinkButton)e.Row.Cells[5].Controls[0];
            bt.Visible = false;
            e.Row.BackColor = System.Drawing.Color.LightGray;
        }
    }

Is there a command that does?

You're using junit.framework.Assert instead of org.junit.Assert.

You can have it this way:

It is important to mind the commas after each struct item or set of items.

earnings := []LineItemsType{

        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,
                },

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,
                },

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
    }

for i in growthRates:  
    fund = fund * (1 + 0.01 * growthRates) + depositPerYear

should be:

for i in growthRates:  
    fund = fund * (1 + 0.01 * i) + depositPerYear

You are multiplying 0.01 with the growthRates list object. Multiplying a list by an integer is valid (it's overloaded syntactic sugar that allows you to create an extended a list with copies of its element references).

Example:

>>> 2 * [1,2]
[1, 2, 1, 2]

Or you can access root terminal by typing sudo -s

You can install the dateutil library. Its parse function can figure out what format a string is in without having to specify the format like you do with datetime.strptime.

from dateutil.parser import parse
dt = parse('Mon Feb 15 2010')
print(dt)
# datetime.datetime(2010, 2, 15, 0, 0)
print(dt.strftime('%d/%m/%Y'))
# 15/02/2010

If you are accessing your repositories over the SSH protocol, you will receive a warning message each time your client connects to a new IP address for github.com. As long as the IP address from the warning is in the range of IP addresses , you shouldn't be concerned. Specifically, the new addresses that are being added this time are in the range from 192.30.252.0 to 192.30.255.255. The warning message looks like this:

Warning: Permanently added the RSA host key for IP address '$IP' to the list of

To mimic Bash's type -P cmd, we can use the POSIX compliant env -i type cmd 1>/dev/null 2>&1.

man env
# "The option '-i' causes env to completely ignore the environment it inherits."
# In other words, there are no aliases or functions to be looked up by the type command.

ls() { echo 'Hello, world!'; }

ls
type ls
env -i type ls

cmd=ls
cmd=lsx
env -i type $cmd 1>/dev/null 2>&1 || { echo "$cmd not found"; exit 1; }

The answer about "short-circuiting" is potentially misleading, but has some truth (see below). In the R/S language, && and || only evaluate the first element in the first argument. All other elements in a vector or list are ignored regardless of the first ones value. Those operators are designed to work with the if (cond) {} else{} construction and to direct program control rather than construct new vectors.. The & and the | operators are designed to work on vectors, so they will be applied "in parallel", so to speak, along the length of the longest argument. Both vectors need to be evaluated before the comparisons are made. If the vectors are not the same length, then recycling of the shorter argument is performed.

When the arguments to && or || are evaluated, there is "short-circuiting" in that if any of the values in succession from left to right are determinative, then evaluations cease and the final value is returned.

> if( print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(FALSE && print(1) ) {print(2)} else {print(3)} # `print(1)` not evaluated
[1] 3
> if(TRUE && print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(TRUE && !print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 3
> if(FALSE && !print(1) ) {print(2)} else {print(3)}
[1] 3

The advantage of short-circuiting will only appear when the arguments take a long time to evaluate. That will typically occur when the arguments are functions that either process larger objects or have mathematical operations that are more complex.

The answer I would provide is that a keystore file is to authenticate yourself to anyone who is asking. It isn't restricted to just signing .apk files, you can use it to store personal certificates, sign data to be transmitted and a whole variety of authentication.

In terms of what you do with it for Android and probably what you're looking for since you mention signing apk's, it is your certificate. You are branding your application with your credentials. You can brand multiple applications with the same key, in fact, it is recommended that you use one certificate to brand multiple applications that you write. It easier to keep track of what applications belong to you.

I'm not sure what you mean by implications. I suppose it means that no one but the holder of your certificate can update your application. That means that if you release it into the wild, lose the cert you used to sign the application, then you cannot release updates so keep that cert safe and backed up if need be.

But apart from signing apks to release into the wild, you can use it to authenticate your device to a server over SSL if you so desire, (also Android related) among other functions.

The basic formula to reverse positive to negative or negative to positive:

i - (i * 2)

I had a similar related question: What if you wanted the original object format back (with key names, e.g. FOO, BAR)?

Jq provides to_entries and from_entries to convert between objects and key-value pair arrays. That along with map around the select

These functions convert between an object and an array of key-value pairs. If to_entries is passed an object, then for each k: v entry in the input, the output array includes {"key": k, "value": v}.

from_entries does the opposite conversion, and with_entries(foo) is a shorthand for to_entries | map(foo) | from_entries, useful for doing some operation to all keys and values of an object. from_entries accepts key, Key, name, Name, value and Value as keys.

jq15 < json 'to_entries | map(select(.value.location=="Stockholm")) | from_entries'

{
  "FOO": {
    "name": "Donald",
    "location": "Stockholm"
  },
  "BAR": {
    "name": "Walt",
    "location": "Stockholm"
  }
}

Using the with_entries shorthand, this becomes:

jq15 < json 'with_entries(select(.value.location=="Stockholm"))'
{
  "FOO": {
    "name": "Donald",
    "location": "Stockholm"
  },
  "BAR": {
    "name": "Walt",
    "location": "Stockholm"
  }
}

iframe is also vulnerable to Cross Frame Scripting:

• https://www.owasp.org/index.php/Cross_Frame_Scripting

You need something like this:

foreach(DataColumn c in dr.Table.Columns)
{
  MessageBox.Show(c.ColumnName);
}

Or just use $json as an object:

$json->$user = array("first" => $first, "last" => $last);

This is how it is returned without the second parameter (as an instance of stdClass).

I think the error because the elements are undefined ,so you need to add window.onload event which this event will defined your elements when the window is loaded.

window.addEventListener('load',Loaded,false);


    function Loaded(){
    var myButton = document.getElementById("myButton");
    var myTextfield = document.getElementById("myTextfield");

    function greetUser(userName) {
    var greeting = "Hello " + userName + "!";
    document.getElementsByTagName ("h2")[0].innerHTML = greeting;
    }

    myButton.onclick = function() {
    var userName = myTextfield.value;
    greetUser(userName);

    return false;
    }
    }

I can't repro, but I suspect that in your actual code there is a constraint somewhere that T : class - you need to propagate that to make the compiler happy, for example (hard to say for sure without a repro example):

public class Derived<SomeModel> : Base<SomeModel> where SomeModel : class, IModel
                                                                    ^^^^^
                                                                 see this bit

You can consider using memory-mapped files, via FileChannels .

Generally a lot faster for large files. There are performance trade-offs that could make it slower, so YMMV.

Related answer: Java NIO FileChannel versus FileOutputstream performance / usefulness

After playing around with other answer, here is my solution for this task. Implementing this way helps me centralize cleanup in one place, preventing double handling the cleanup.

1. I would like to route all other exiting codes to 'exit' code.

const others = [`SIGINT`, `SIGUSR1`, `SIGUSR2`, `uncaughtException`, `SIGTERM`]
others.forEach((eventType) => {
    process.on(eventType, exitRouter.bind(null, { exit: true }));
})

2. What the exitRouter does is calling process.exit()

function exitRouter(options, exitCode) {
   if (exitCode || exitCode === 0) console.log(`ExitCode ${exitCode}`);
   if (options.exit) process.exit();
}

3. On 'exit', handle the clean up with a new function

function exitHandler(exitCode) {
  console.log(`ExitCode ${exitCode}`);
  console.log('Exiting finally...')
}

process.on('exit', exitHandler)

For the demo purpose, this is link to my gist. In the file, i add a setTimeout to fake the process running.

If you run node node-exit-demo.js and do nothing, then after 2 seconds, you see the log:

The service is finish after a while.
ExitCode 0
Exiting finally...

Else if before the service finish, you terminate by ctrl+C, you'll see:

^CExitCode SIGINT
ExitCode 0
Exiting finally...

What happened is the Node process exited initially with code SIGINT, then it routes to process.exit() and finally exited with exit code 0.

I would recommend the rename command for this. Type ren /? at the command line for more help.

In your case, you need to use Sprintf() for format string.

func Sprintf(format string, a ...interface{}) string

Sprintf formats according to a format specifier and returns the resulting string.

s := fmt.Sprintf("Good Morning, This is %s and I'm living here from last %d years ", "John", 20)

Your output will be :

Good Morning, This is John and I'm living here from last 20 years.

I can't tell from the context you supply, but if it's something you just need to do at app startup, you can still use Server.MapPath in WebApiHttpApplication; e.g. in Application_Start().

I'm just answering your direct question; the already-mentioned HostingEnvironment.MapPath() is probably the preferred solution.

You can have multiple CSS declarations for the same properties by separating them with commas:

.abc, .xyz {
   margin-left: 20px;
}

This is one way without using time a zone:

LocalDateTime now = LocalDateTime.now();
long epoch = (now.getLong(ChronoField.EPOCH_DAY) * 86400000) + now.getLong(ChronoField.MILLI_OF_DAY);

Change the access permission of the docker.sock file

chmod 777 /var/run/docker.sock

or u can use sudo in the start of the command.

chmod 777 will allow all actions for all users while chmod 666 will allow all users to read and write but cannot execute the file.

That seems to me the easiest way. Structure members can be initialized using curly braces ‘{}’. For example, following is a valid initialization.

struct Point 
{ 
   int x, y; 
};  

int main() 
{ 
   // A valid initialization. member x gets value 0 and y 
   // gets value 1.  The order of declaration is followed. 
   struct Point p1 = {0, 1};  
}

There is good information about structs in c++ - https://www.geeksforgeeks.org/structures-in-cpp/

I think df['word'].value_counts() should serve. By skipping the groupby machinery, you'll save some time. I'm not sure why count should be much slower than max. Both take some time to avoid missing values. (Compare with size.)

In any case, value_counts has been specifically optimized to handle object type, like your words, so I doubt you'll do much better than that.

You can use slice with no arguments to copy an array:

var foo,
    bar;
foo = [3,1,2];
bar = foo.slice().sort();

A break will allow you continue processing in the function. Just returning out of the switch is fine if that's all you want to do in the function.

I had the same issue too and this worked for me try:

this.http.request('http://thecatapi.com/api/images/get?format=html&results_per_page=10').
  subscribe((res) => {
    let resSTR = JSON.stringify(res);
    let resJSON = JSON.parse(resStr);
    console.log(resJSON._body);
  })

            "analyze_wildcard" : true,
            "allow_leading_wildcard": true
        }
    }

The lookup time is slow because when you use mmap to does not load content of array to memory when you invoke load method. Data is lazy loaded when particular data is needed. And this happens in lookup in your case. But second lookup won`t be so slow.

This is nice feature of mmap when you have a big array you do not have to load whole data into memory.

To solve your can use joblib you can dump any object you want using joblib.dump even two or more numpy arrays, see the example

firstArray = np.arange(100)
secondArray = np.arange(50)
# I will put two arrays in dictionary and save to one file
my_dict = {'first' : firstArray, 'second' : secondArray}
joblib.dump(my_dict, 'file_name.dat')

I posted too soon however the ways to configure are given in below link

http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html

and way to get access keys are given in below link

http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-set-up.html#cli-signup

You could use the object data type:

>>> import numpy
>>> s = numpy.array(['a', 'b', 'dude'], dtype='object')
>>> s[0] += 'bcdef'
>>> s
array([abcdef, b, dude], dtype=object)

If chmod not working then you also try

import os
os.system('sh script.sh')
#you can also use bash instead of sh

test by me thanks

The command clause does work as @Karthik says above.

As a simple example, the following service will have a -inMemory added to its ENTRYPOINT when docker-compose up is run.

version: '2'
services:
  local-dynamo:
    build: local-dynamo
    image: spud/dynamo
    command: -inMemory

I would like to point out that if you can't find "Link Binaries With Libraries" in your build phases tab click the "Add build phase" button in the lower right corner.

From Wikipedia:

not sure if it'll work in your scenario, but try adding the following to your web.config under <system.web>:

  <system.web>
    <customErrors mode="Off" />
  ...
  </system.web>

works in my instance.

Some Google tooling such as GWT has an embedded version of commons-codec with a pre-1.4 Base64 class. You may need to make such tooling JARs inaccessible to your code by refactoring your project such that only the parts of your code that need that tooling can see the dependency.

I was gone through same problem solved after lot efforts. It is because of npm version is not compatible with gprc version. So we need to update the npm.

npm update
npm install 

Swift 2

Simple

let str = "My String"
let subStr = str[str.startIndex.advancedBy(3)...str.startIndex.advancedBy(7)]
//"Strin"

Swift 3

let startIndex = str.index(str.startIndex, offsetBy: 3)
let endIndex = str.index(str.startIndex, offsetBy: 7)

str[startIndex...endIndex]       // "Strin"
str.substring(to: startIndex)    // "My "
str.substring(from: startIndex)  // "String"

Swift 4

substring(to:) and substring(from:) are deprecated in Swift 4.

String(str[..<startIndex])    // "My "
String(str[startIndex...])    // "String"
String(str[startIndex...endIndex])    // "Strin"

Yup, As @luizfelippe mentioned Session class has been removed since SDK 4.0. We need to use LoginManager.

I just looked into LoginButton class for logout. They are making this kind of check. They logs out only if accessToken is not null. So, I think its better to have this in our code too..

AccessToken accessToken = AccessToken.getCurrentAccessToken();
if(accessToken != null){
    LoginManager.getInstance().logOut();
}

While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event argument to the setMaster function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):

function AdminController($scope) {    
  $scope.setMaster = function(obj, $event){
    console.log($event.target);
  }
}

this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.

The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event argument) would be:

<div ng-controller="AdminController">
    <ul class="list-holder">
        <li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
            <a ng-click="setMaster(section)">{{section.name}}</a>
        </li>
    </ul>
    <hr>
    {{selected | json}}
</div>

where methods in the controller would look like this:

$scope.setMaster = function(section) {
    $scope.selected = section;
}

$scope.isSelected = function(section) {
    return $scope.selected === section;
}

Here is the complete jsFiddle: http://jsfiddle.net/pkozlowski_opensource/WXJ3p/15/

This might not be the best method, but you can ignore the conversion error if all else fails. Mine was an issue of nulls not converting properly, so I just ignored the error and the dates came in as dates and the nulls came in as nulls, so no data quality issues--not that this would always be the case. To do this, right click on your source, click Edit, then Error Output. Go to the column that's giving you grief and under Error change it to Ignore Failure.

This issue has already been resolved here : What is the best way to detect a mobile device in jQuery?.

On the accepted answer, they basically test if it's an iPhone, an iPod, an Android device or whatever to return true. Just keep the ones you want for instance if( /Android/i.test(navigator.userAgent) ) { // some code.. } will return true only for Android user-agents.

However, user-agents are not really reliable since they can be changed. The best thing is still to develop something universal for all mobile platforms.

The accepted answer has to be really altered otherwise not working. The getDecimalFormatSymbols makes a defensive copy. Thus,

DecimalFormat formatter = (DecimalFormat) NumberFormat.getInstance(Locale.US);
DecimalFormatSymbols symbols = formatter.getDecimalFormatSymbols();

symbols.setGroupingSeparator(' ');
formatter.setDecimalFormatSymbols(symbols);
System.out.println(formatter.format(bd.longValue()));

The new line is this one: formatter.setDecimalFormatSymbols(symbols);

I'm using NodeJS and got the same error. Like the other answers, the problem was also because JQuery needed to be loaded before Bootstrap; however, because of the NodeJS characteristics, this change had to be aplied in the pipeline.js file.

The change in pipeline.js was like this:

var jsFilesToInject = [
  // Dependencies like jQuery, or Angular are brought in here
  'js/dependencies/angular.1.3.js',
  'js/dependencies/jquery.js',
  'js/dependencies/bootstrap.js',
  'js/dependencies/**/*.js',
];

I'm also using grunt to help, and it automatically changed the order in the main html page:

<!--SCRIPTS-->
  <script src="/js/dependencies/angular.1.3.js"></script>
  <script src="/js/dependencies/jquery.js"></script>
  <script src="/js/dependencies/bootstrap.js"></script>
  <!-- other dependencies -->
<!--SCRIPTS END-->

Hope it helps! You didn't said what your environment was, so I decided to post this answer.

Thankfully(?), in SQL Server 2012+, you can now use FORMAT() to achieve this:

FORMAT(@s,'#,0.0000')

[Query]:

declare @s decimal(18,10);
set @s = 1234.1234567;
select replace(convert(varchar,cast(floor(@s) as money),1),'.00',
    '.'+right(cast(@s * 10000 +10000.5 as int),4))

In the first part, we use MONEY->VARCHAR to produce the commas, but FLOOR() is used to ensure the decimals go to .00. This is easily identifiable and replaced with the 4 digits after the decimal place using a mixture of shifting (*10000) and CAST as INT (truncation) to derive the digits.

[Results]:

|   COLUMN_0 |
--------------
| 1,234.1235 |

But unless you have to deliver business reports using SQL Server Management Studio or SQLCMD, this is NEVER the correct solution, even if it can be done. Any front-end or reporting environment has proper functions to handle display formatting.

In my case (Oracle), it's WHERE REGEXP_LIKE(column, 'regex.*'). See here:

SQL Function

Description

---

REGEXP_LIKE

This function searches a character column for a pattern. Use this function in the WHERE clause of a query to return rows matching the regular expression you specify.

...

REGEXP_REPLACE

This function searches for a pattern in a character column and replaces each occurrence of that pattern with the pattern you specify.

...

REGEXP_INSTR

This function searches a string for a given occurrence of a regular expression pattern. You specify which occurrence you want to find and the start position to search from. This function returns an integer indicating the position in the string where the match is found.

...

REGEXP_SUBSTR

This function returns the actual substring matching the regular expression pattern you specify.

(Of course, REGEXP_LIKE only matches queries containing the search string, so if you want a complete match, you'll have to use '^$' for a beginning (^) and end ($) match, e.g.: '^regex.*$'.)

I haven't tested your code, just tried to help you understand how it operates in comment;

WITH
  cteReports (EmpID, FirstName, LastName, MgrID, EmpLevel)
  AS
  (
-->>>>>>>>>>Block 1>>>>>>>>>>>>>>>>>
-- In a rCTE, this block is called an [Anchor]
-- The query finds all root nodes as described by WHERE ManagerID IS NULL
    SELECT EmployeeID, FirstName, LastName, ManagerID, 1
    FROM Employees
    WHERE ManagerID IS NULL
-->>>>>>>>>>Block 1>>>>>>>>>>>>>>>>>
    UNION ALL
-->>>>>>>>>>Block 2>>>>>>>>>>>>>>>>>    
-- This is the recursive expression of the rCTE
-- On the first "execution" it will query data in [Employees],
-- relative to the [Anchor] above.
-- This will produce a resultset, we will call it R{1} and it is JOINed to [Employees]
-- as defined by the hierarchy
-- Subsequent "executions" of this block will reference R{n-1}
    SELECT e.EmployeeID, e.FirstName, e.LastName, e.ManagerID,
      r.EmpLevel + 1
    FROM Employees e
      INNER JOIN cteReports r
        ON e.ManagerID = r.EmpID
-->>>>>>>>>>Block 2>>>>>>>>>>>>>>>>>
  )
SELECT
  FirstName + ' ' + LastName AS FullName,
  EmpLevel,
  (SELECT FirstName + ' ' + LastName FROM Employees
    WHERE EmployeeID = cteReports.MgrID) AS Manager
FROM cteReports
ORDER BY EmpLevel, MgrID

The simplest example of a recursive CTE I can think of to illustrate its operation is;

;WITH Numbers AS
(
    SELECT n = 1
    UNION ALL
    SELECT n + 1
    FROM Numbers
    WHERE n+1 <= 10
)
SELECT n
FROM Numbers

Q 1) how value of N is getting incremented. if value is assign to N every time then N value can be incremented but only first time N value was initialize.

A1: In this case, N is not a variable. N is an alias. It is the equivalent of SELECT 1 AS N. It is a syntax of personal preference. There are 2 main methods of aliasing columns in a CTE in T-SQL. I've included the analog of a simple CTE in Excel to try and illustrate in a more familiar way what is happening.

--  Outside
;WITH CTE (MyColName) AS
(
    SELECT 1
)
-- Inside
;WITH CTE AS
(
    SELECT 1 AS MyColName
    -- Or
    SELECT MyColName = 1  
    -- Etc...
)

Q 2) now here about CTE and recursion of employee relation the moment i add two manager and add few more employee under second manager then problem start. i want to display first manager detail and in the next rows only those employee details will come those who are subordinate of that manager

A2:

Does this code answer your question?

--------------------------------------------
-- Synthesise table with non-recursive CTE
--------------------------------------------
;WITH Employee (ID, Name, MgrID) AS 
(
    SELECT 1,      'Keith',      NULL   UNION ALL
    SELECT 2,      'Josh',       1      UNION ALL
    SELECT 3,      'Robin',      1      UNION ALL
    SELECT 4,      'Raja',       2      UNION ALL
    SELECT 5,      'Tridip',     NULL   UNION ALL
    SELECT 6,      'Arijit',     5      UNION ALL
    SELECT 7,      'Amit',       5      UNION ALL
    SELECT 8,      'Dev',        6   
)
--------------------------------------------
-- Recursive CTE - Chained to the above CTE
--------------------------------------------
,Hierarchy AS
(
    --  Anchor
    SELECT   ID
            ,Name
            ,MgrID
            ,nLevel = 1
            ,Family = ROW_NUMBER() OVER (ORDER BY Name)
    FROM Employee
    WHERE MgrID IS NULL

    UNION ALL
    --  Recursive query
    SELECT   E.ID
            ,E.Name
            ,E.MgrID
            ,H.nLevel+1
            ,Family
    FROM Employee   E
    JOIN Hierarchy  H ON E.MgrID = H.ID
)
SELECT *
FROM Hierarchy
ORDER BY Family, nLevel

Another one sql with tree structure

SELECT ID,space(nLevel+
                    (CASE WHEN nLevel > 1 THEN nLevel ELSE 0 END)
                )+Name
FROM Hierarchy
ORDER BY Family, nLevel

Use:

if (d % 1.0 != 0)
    return String.format("%s", d);
else
    return String.format("%.0f", d);

This should work with the extreme values supported by Double. It yields:

0.12
12
12.144252
0

you can create bitmaps for the highes resolution / size your application will run and resize them in the code (at run time)

check this article http://nuvornapps-en.blogspot.com.es/

You are working way too hard. Your entire script should be:

if mkdir "$lockdir" 2> /dev/null; then 
  echo lock acquired
else
  echo could not acquire lock >&2
fi

but even that is probably too verbose. I would code it:

mkdir "$lockdir" || exit 1

but the resulting error message is a bit obscure.

With fscanf read the file until you encounter ';' or \n, then you can just skip it with fscang(f, "%*c").

int main()
{
    char str[128];
    int result;
    FILE* f = fopen("test.txt", "r");
    ...
    
    do {
        result = fscanf(f, "%127[^;\n]", str);
        
        if(result == 0)
        {
            result = fscanf(f, "%*c");
        }
        else
        {
            //whatever you want to do with your value
            printf("%s\n", str);
        }
        
    } while(result != EOF);

    return 0;
}

You need only one line before the declaration of the class Animal for correct polymorphic serialization/deserialization:

@JsonTypeInfo(use = JsonTypeInfo.Id.CLASS, include = JsonTypeInfo.As.PROPERTY, property = "@class")
public abstract class Animal {
   ...
}

This line means: add a meta-property on serialization or read a meta-property on deserialization (include = JsonTypeInfo.As.PROPERTY) called "@class" (property = "@class") that holds the fully-qualified Java class name (use = JsonTypeInfo.Id.CLASS).

So, if you create a JSON directly (without serialization) remember to add the meta-property "@class" with the desired class name for correct deserialization.

bit of a strange way to do this but use the resolution as the aspect. E.G.

1024:768

or you can try

var w = screen.width;
var h = screen.height;
for(var i=1,asp=w/h;i<5000;i++){
  if(asp*i % 1==0){
    i=9999;
    document.write(asp*i,":",1*i);
  }
}

new to android.. tried

getWindow().getDecorView().clearFocus();

it works for me..

just to add .. your layout should have:

 android:focusable="true"
 android:focusableInTouchMode="true"

textview.setText(Html.fromHtml("<font color='rgb'>"+text contain+"</font>"));

It will give the color exactly what you have made in html editor , just set the textview and concat it with the textview value. Android does not support span color, change it to font color in editor and you are all set to go.

These are different Form content types defined by W3C. If you want to send simple text/ ASCII data, then x-www-form-urlencoded will work. This is the default.

But if you have to send non-ASCII text or large binary data, the form-data is for that.

You can use Raw if you want to send plain text or JSON or any other kind of string. Like the name suggests, Postman sends your raw string data as it is without modifications. The type of data that you are sending can be set by using the content-type header from the drop down.

Binary can be used when you want to attach non-textual data to the request, e.g. a video/audio file, images, or any other binary data file.

Refer to this link for further reading: Forms in HTML documents

You can assign one color to every functionality to make it more useful.

#define Color_Red "\33[0:31m\\]" // Color Start
#define Color_end "\33[0m\\]" // To flush out prev settings
#define LOG_RED(X) printf("%s %s %s",Color_Red,X,Color_end)

foo()
{
LOG_RED("This is in Red Color");
}

Like wise you can select different color codes and make this more generic.

Here's a script that will use the Google API to acquire the users postal code and populate an input field.

function postalCodeLookup(input) {
    var head= document.getElementsByTagName('head')[0],
        script= document.createElement('script');
    script.src= '//maps.googleapis.com/maps/api/js?sensor=false';
    head.appendChild(script);
    script.onload = function() {
        if (navigator.geolocation) {
            var a = input,
                fallback = setTimeout(function () {
                    fail('10 seconds expired');
                }, 10000);

            navigator.geolocation.getCurrentPosition(function (pos) {
                clearTimeout(fallback);
                var point = new google.maps.LatLng(pos.coords.latitude, pos.coords.longitude);
                new google.maps.Geocoder().geocode({'latLng': point}, function (res, status) {
                    if (status == google.maps.GeocoderStatus.OK && typeof res[0] !== 'undefined') {
                        var zip = res[0].formatted_address.match(/,\s\w{2}\s(\d{5})/);
                        if (zip) {
                            a.value = zip[1];
                        } else fail('Unable to look-up postal code');
                    } else {
                        fail('Unable to look-up geolocation');
                    }
                });
            }, function (err) {
                fail(err.message);
            });
        } else {
            alert('Unable to find your location.');
        }
        function fail(err) {
            console.log('err', err);
            a.value('Try Again.');
        }
    };
}

You can adjust accordingly to acquire different information. For more info, check out the Google Maps API documentation.

Try this:

function welcomeMessage()
{
    var shape1 = new Shape();
    //alert(shape1.draw());
    alert(shape1.hasOwnProperty("name"));
}

When working with reflection in JavaScript, member objects are always refered to as the name as a string. For example:

for(i in obj) { ... }

The loop iterator i will be hold a string value with the name of the property. To use that in code you have to address the property using the array operator like this:

 for(i in obj) {
   alert("The value of obj." + i + " = " + obj[i]);
 }

Like the rest of you, I've spent days trying to figure this out. I've been down this thread trying every combination of what you have all said, and nothing. I finally went to AppData/Local/Microsoft/VisualStudio and deleted all the folders in there. Then proceeded to turn off everything in my Anti virus and I finally got the basic installation to go all the way through. Frustrating, but hopefully this will help someone else who has tried everything.

This problem can be solved with standard tools, but there are sufficiently many traps for the unwary that I recommend you install the flip command, which was written over 20 years ago by Rahul Dhesi, the author of zoo. It does an excellent job converting file formats while, for example, avoiding the inadvertant destruction of binary files, which is a little too easy if you just race around altering every CRLF you see...

Similar to the above solutions I used @Input() in a directive and able to pass multiple arrays of values in the directive.

selector: '[selectorHere]',

@Input() options: any = {};

Input.html

<input selectorHere [options]="selectorArray" />

Array from TS file

selectorArray= {
  align: 'left',
  prefix: '$',
  thousands: ',',
  decimal: '.',
  precision: 2
};

4. Check the 'disable cache' checkbox.

http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#intern()

Basically doing String.intern() on a series of strings will ensure that all strings having same contents share same memory. So if you have list of names where 'john' appears 1000 times, by interning you ensure only one 'john' is actually allocated memory.

This can be useful to reduce memory requirements of your program. But be aware that the cache is maintained by JVM in permanent memory pool which is usually limited in size compared to heap so you should not use intern if you don't have too many duplicate values.

More on memory constraints of using intern()

On one hand, it is true that you can remove String duplicates by internalizing them. The problem is that the internalized strings go to the Permanent Generation, which is an area of the JVM that is reserved for non-user objects, like Classes, Methods and other internal JVM objects. The size of this area is limited, and is usually much smaller than the heap. Calling intern() on a String has the effect of moving it out from the heap into the permanent generation, and you risk running out of PermGen space.

-- From: http://www.codeinstructions.com/2009/01/busting-javalangstringintern-myths.html

From JDK 7 (I mean in HotSpot), something has changed.

In JDK 7, interned strings are no longer allocated in the permanent generation of the Java heap, but are instead allocated in the main part of the Java heap (known as the young and old generations), along with the other objects created by the application. This change will result in more data residing in the main Java heap, and less data in the permanent generation, and thus may require heap sizes to be adjusted. Most applications will see only relatively small differences in heap usage due to this change, but larger applications that load many classes or make heavy use of the String.intern() method will see more significant differences.

-- From Java SE 7 Features and Enhancements

Update: Interned strings are stored in main heap from Java 7 onwards. http://www.oracle.com/technetwork/java/javase/jdk7-relnotes-418459.html#jdk7changes

For me Criteria is a quite easy to Understand and making Dynamic queries. But the flaw i say so far is that It loads all many-one etc relations because we have only three types of FetchModes i.e Select, Proxy and Default and in all these cases it loads many-one (may be i am wrong if so help me out :))

2nd issue with Criteria is that it loads complete object i.e if i want to just load EmpName of an employee it wont come up with this insted it come up with complete Employee object and i can get EmpName from it due to this it really work bad in reporting. where as HQL just load(did't load association/relations) what u want so increase performance many times.

One feature of Criteria is that it will safe u from SQL Injection because of its dynamic query generation where as in HQL as ur queries are either fixed or parameterised so are not safe from SQL Injection.

Also if you write HQL in ur aspx.cs files, then you are tightly coupled with ur DAL.

Overall my conclusion is that there are places where u can't live without HQL like reports so use them else Criteria is more easy to manage.

As of 5.5 you can run Kernel > Restart and Run All

Update February 2016

This took me hours to solve independently. Yes, this problem does still exist with latest Vagrant and Virtual Box installs:

?  vagrant -v
Vagrant 1.8.1
?  vboxmanage -v
5.0.14r105127

The symptoms for me were messages something like:

Checking for guest additions in VM... The guest additions on this VM do not match the installed version of VirtualBox!

followed by a failure to mount NFS drives.

1). Install the vagrant-vbguest plugin.

Depending on version of Vagrant you are using, issue one of the following commands:

# For vagrant < 1.1.5
$ vagrant gem install vagrant-vbguest

# For vagrant 1.1.5+
$ vagrant plugin install vagrant-vbguest

Next, do vagrant halt, followed by vagrant up - chances are you still have issues.

2). ssh into your guest and setup a soft link to the correct version of Guest Additions (here, 5.0.14).

$ vagrant ssh

$ sudo ln -s /opt/VBoxGuestAdditions-5.0.14/lib/VBoxGuestAdditions /usr/lib/VBoxGuestAdditions
$ exit

$ vagrant reload

You should be all good. By default, the mounted drive on guest is at /vagrant

Final comment:

IF you still have problems related to mounting NFS drives, then here is a workaround that worked for me. I had a vagrantfile with config something like:

Simply remove the mount type information, and slim down the mount_options settings so they work universally. Vagrant will now automatically choose the best synced folder option for your environment.

You can use negative integers with the slicing operator for that. Here's an example using the python CLI interpreter:

>>> a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
>>> a
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
>>> a[-9:]
[4, 5, 6, 7, 8, 9, 10, 11, 12]

the important line is a[-9:]

I wanted to share a solution I came up with using jQuery that works if you have multiple YouTube videos embedded on a single page. In my case, I have defined a modal popup for each video as follows:

<div id="videoModalXX">
...
    <button onclick="stopVideo(videoID);" type="button" class="close"></button>
    ...
    <iframe width="90%" height="400" src="//www.youtube-nocookie.com/embed/video_id?rel=0&enablejsapi=1&version=3" frameborder="0" allowfullscreen></iframe>
...
</div>

In this case, videoModalXX represents a unique id for the video. Then, the following function stops the video:

function stopVideo(id)
{
    $("#videoModal" + id + " iframe")[0].contentWindow.postMessage('{"event":"command","func":"pauseVideo","args":""}', '*');
}

I like this approach because it keeps the video paused where you left off in case you want to go back and continue watching later. It works well for me because it's looking for the iframe inside of the video modal with a specific id. No special YouTube element ID is required. Hopefully, someone will find this useful as well.

I don't know Mathematica . . . too bad. But I like the answer above, for the most part.

Still there is a major flaw in relying on the stripes alone to glean the answer (I personally don't have a problem with one manual adjustment). There is an example (listed by Brett Champion, here) presented which shows that they, at times, break up the shirt pattern. So then it becomes a more complex pattern.

I would try an approach of shape id and colors, along with spacial relations. Much like face recognition, you could look for geometric patterns at certain ratios from each other. The caveat is that usually one or more of those shapes is occluded.

Get a white balance on the image, and red a red balance from the image. I believe Waldo is always the same value/hue, but the image may be from a scan, or a bad copy. Then always refer to an array of the colors that Waldo actually is: red, white, dark brown, blue, peach, {shoe color}.

There is a shirt pattern, and also the pants, glasses, hair, face, shoes and hat that define Waldo. Also, relative to other people in the image, Waldo is on the skinny side.

So, find random people to obtain an the height of people in this pic. Measure the average height of a bunch of things at random points in the image (a simple outline will produce quite a few individual people). If each thing is not within some standard deviation from each other, they are ignored for now. Compare the average of heights to the image's height. If the ratio is too great (e.g., 1:2, 1:4, or similarly close), then try again. Run it 10(?) of times to make sure that the samples are all pretty close together, excluding any average that is outside some standard deviation. Possible in Mathematica?

This is your Waldo size. Walso is skinny, so you are looking for something 5:1 or 6:1 (or whatever) ht:wd. However, this is not sufficient. If Waldo is partially hidden, the height could change. So, you are looking for a block of red-white that ~2:1. But there has to be more indicators.

1. Waldo has glasses. Search for two circles 0.5:1 above the red-white.
2. Blue pants. Any amount of blue at the same width within any distance between the end of the red-white and the distance to his feet. Note that he wears his shirt short, so the feet are not too close.
3. The hat. Red-white any distance up to twice the top of his head. Note that it must have dark hair below, and probably glasses.
4. Long sleeves. red-white at some angle from the main red-white.
5. Dark hair.
6. Shoe color. I don't know the color.

Any of those could apply. These are also negative checks against similar people in the pic -- e.g., #2 negates wearing a red-white apron (too close to shoes), #5 eliminates light colored hair. Also, shape is only one indicator for each of these tests . . . color alone within the specified distance can give good results.

This will narrow down the areas to process.

Storing these results will produce a set of areas that should have Waldo in it. Exclude all other areas (e.g., for each area, select a circle twice as big as the average person size), and then run the process that @Heike laid out with removing all but red, and so on.

Any thoughts on how to code this?

Edit:

Thoughts on how to code this . . . exclude all areas but Waldo red, skeletonize the red areas, and prune them down to a single point. Do the same for Waldo hair brown, Waldo pants blue, Waldo shoe color. For Waldo skin color, exclude, then find the outline.

Next, exclude non-red, dilate (a lot) all the red areas, then skeletonize and prune. This part will give a list of possible Waldo center points. This will be the marker to compare all other Waldo color sections to.

From here, using the skeletonized red areas (not the dilated ones), count the lines in each area. If there is the correct number (four, right?), this is certainly a possible area. If not, I guess just exclude it (as being a Waldo center . . . it may still be his hat).

Then check if there is a face shape above, a hair point above, pants point below, shoe points below, and so on.

No code yet -- still reading the docs.

using swagger-ui.js

you can do this -

_.forEach({ 'a': 1, 'b': 2 }, function(n, key) {
    console.log(n, key);
 });

do you use Bash? Go to the file .bashrc in your home directory and set the variable, then export it.

DISPLAY=localhost:0.0 ; export DISPLAY

you can use /etc/bashrc if you want to do it for all the users.

You may also want to look in ~/.bash_profile and /etc/profile

EDIT:

function get_xserver ()
{
    case $TERM in
       xterm )
            XSERVER=$(who am i | awk '{print $NF}' | tr -d ')''(' )    
            XSERVER=${XSERVER%%:*}
            ;;
        aterm | rxvt)           
            ;;
    esac  
}

if [ -z ${DISPLAY:=""} ]; then
    get_xserver
    if [[ -z ${XSERVER}  || ${XSERVER} == $(hostname) || \
      ${XSERVER} == "unix" ]]; then 
        DISPLAY=":0.0"          # Display on local host.
    else
        DISPLAY=${XSERVER}:0.0  # Display on remote host.

It is incredible that there are so many answers but none answers the question:

"When I was asking this question, I asked for a way of opening a UTF-8 CSV file in Excel without any problems for a user,..."

The answer marked as the accepted answer with 200+ up-votes is useless for me because I don't want to give my users a manual how to configure Excel. Apart from that: this manual will apply to one Excel version but other Excel versions have different menus and configuration dialogs. You would need a manual for each Excel version.

So the question is how to make Excel show UTF8 data with a simple double click?

Well at least in Excel 2007 this is not possible if you use CSV files because the UTF8 BOM is ignored and you will see only garbage. This is already part of the question of Lyubomyr Shaydariv:

"I also tried specifying UTF-8 BOM EF BB BF, but Excel ignores that."

I make the same experience: Writing russian or greek data into a UTF8 CSV file with BOM results in garbage in Excel:

Content of UTF8 CSV file:

Colum1;Column2
Val1;Val2
?????????;T??????

Result in Excel 2007:

A solution is to not use CSV at all. This format is implemented so stupidly by Microsoft that it depends on the region settings in control panel if comma or semicolon is used as separator. So the same CSV file may open correctly on one computer but on anther computer not. "CSV" means "Comma Separated Values" but for example on a german Windows by default semicolon must be used as separator while comma does not work. (Here it should be named SSV = Semicolon Separated Values) CSV files cannot be interchanged between different language versions of Windows. This is an additional problem to the UTF-8 problem.

Excel exists since decades. It is a shame that Microsoft was not able to implement such a basic thing as CSV import in all these years.

However, if you put the same values into a HTML file and save that file as UTF8 file with BOM with the file extension XLS you will get the correct result.

Content of UTF8 XLS file:

<table>
<tr><td>Colum1</td><td>Column2</td></tr>
<tr><td>Val1</td><td>Val2</td></tr>
<tr><td>?????????</td><td>T??????</td></tr>
</table>

Result in Excel 2007:

You can even use colors in HTML which Excel will show correctly.

<style>
.Head { background-color:gray; color:white; }
.Red  { color:red; }
</style>
<table border=1>
<tr><td class=Head>Colum1</td><td class=Head>Column2</td></tr>
<tr><td>Val1</td><td>Val2</td></tr>
<tr><td class=Red>?????????</td><td class=Red>T??????</td></tr>
</table>

Result in Excel 2007:

In this case only the table itself has a black border and lines. If you want ALL cells to display gridlines this is also possible in HTML:

<html xmlns:x="urn:schemas-microsoft-com:office:excel">
    <head>
        <meta http-equiv="content-type" content="text/plain; charset=UTF-8"/>
        <xml>
            <x:ExcelWorkbook>
                <x:ExcelWorksheets>
                    <x:ExcelWorksheet>
                        <x:Name>MySuperSheet</x:Name>
                        <x:WorksheetOptions>
                            <x:DisplayGridlines/>
                        </x:WorksheetOptions>
                    </x:ExcelWorksheet>
                </x:ExcelWorksheets>
            </x:ExcelWorkbook>
        </xml>
    </head>
    <body>
        <table>
            <tr><td>Colum1</td><td>Column2</td></tr>
            <tr><td>Val1</td><td>Val2</td></tr>
            <tr><td>?????????</td><td>T??????</td></tr>
        </table>
    </body>
</html>

This code even allows to specify the name of the worksheet (here "MySuperSheet")

Both above answers would only return one index if there are multiple rows that take the maximum value. If you want all the rows, there does not seem to have a function. But it is not hard to do. Below is an example for Series; the same can be done for DataFrame:

In [1]: from pandas import Series, DataFrame

In [2]: s=Series([2,4,4,3],index=['a','b','c','d'])

In [3]: s.idxmax()
Out[3]: 'b'

In [4]: s[s==s.max()]
Out[4]: 
b    4
c    4
dtype: int64

I make a (sub)folder named "hide", move the file I don't want committed to there. Then do my commit, ignoring complaint about the missing file. Then move the hidden file from hide back to ./

I know of no downside to this tactic.

AppDomain.CurrentDomain.BaseDirectory

contents in my backup_settings.ini file

[Settings]
year = 2020

python code for reading

import configparser
config = configparser.ConfigParser()
config.read('backup_settings.ini') #path of your .ini file
year = config.get("Settings","year") 
print(year)

for writing or updating

from pathlib import Path
import configparser
myfile = Path('backup_settings.ini')  #Path of your .ini file
config.read(myfile)
config.set('Settings', 'year','2050') #Updating existing entry 
config.set('Settings', 'day','sunday') #Writing new entry
config.write(myfile.open("w"))

output

[Settings]
year = 2050
day = sunday

Regular expressions are very strong but expensive tool. It is valid to use them for checking if the first character is a digit but it is not so elegant :) I prefer this way:

public boolean isLeadingDigit(final String value){
    final char c = value.charAt(0);
    return (c >= '0' && c <= '9');
}

Check again. Use debugger if must. My guess is that for some item in userResponseDetails this query finds no elements:

.Where(y => y.ResponseId.Equals(item.ResponseId))

so you can't call

.First()

on it. Maybe try

.FirstOrDefault()

if it solves the issue.

Do NOT return NULL value! This is purely so that you can see and diagnose where problem is. Handle these cases properly.

If you are using bootstrap.js then the below code might be useful. This is very simple. Dont have to write anything in js to invoke the pop-up.

For case sensitive renaming, git mv somefolder someFolder has worked for me before but didn't today for some reason. So as a workaround I created a new folder temp, moved all the contents of somefolder into temp, deleted somefolder, committed the temp, then created someFolder, moved all the contents of temp into someFolder, deleted temp, committed and pushed someFolder and it worked! Shows up as someFolder in git.

These are the installation i had to run in order to make it work on fedora 22 :-

glibc-2.21-7.fc22.i686

alsa-lib-1.0.29-1.fc22.i686

qt3-3.3.8b-64.fc22.i686

The following SQL statement:

select edition,version from v$instance

returns:

• database edition eg. "XE"
• database version eg. "12.1.0.2.0"

(select privilege on the v$instance view is of course necessary)

select2 has the placeholder parameter. Use that one

$("#state").select2({
   placeholder: "Choose a Country"
 });

one way of doing things is to list commits that are available on one branch but not another.

and then

    public static List<String> splitByComma(String str) {
    Iterable<String> split = Splitter.on(",")
            .omitEmptyStrings()
            .trimResults()
            .split(str);
    return Lists.newArrayList(split);
    }

    public static String joinWithComma(Set<String> words) {
        return Joiner.on(", ").skipNulls().join(words);
    }

enjoy :)

$("#location").change(function(){

    var tag = $("option[value="+$(this).val()+"]", this).attr('mytag');

    $('#setMyTag').val(tag); 

});

Here's my implementation of Dan Tao's answer, allowing for a predicate:

public static bool IsEmpty<TSource>(this IEnumerable<TSource> source, Func<TSource, bool> predicate)
{
    if (source == null) throw new ArgumentNullException();
    if (IsCollectionAndEmpty(source)) return true;
    return !source.Any(predicate);
}

public static bool IsEmpty<TSource>(this IEnumerable<TSource> source)
{
    if (source == null) throw new ArgumentNullException();
    if (IsCollectionAndEmpty(source)) return true;
    return !source.Any();
}

private static bool IsCollectionAndEmpty<TSource>(IEnumerable<TSource> source)
{
    var genericCollection = source as ICollection<TSource>;
    if (genericCollection != null) return genericCollection.Count == 0;
    var nonGenericCollection = source as ICollection;
    if (nonGenericCollection != null) return nonGenericCollection.Count == 0;
    return false;
}

In c# following code insert data into datatable on specified position

DataTable dt = new DataTable();
dt.Columns.Add("SL");
dt.Columns.Add("Amount");

dt.rows.add(1, 1000)
dt.rows.add(2, 2000)

dt.Rows.InsertAt(dt.NewRow(), 3);

var rowPosition = 3;
dt.Rows[rowPosition][dt.Columns.IndexOf("SL")] = 3;
dt.Rows[rowPosition][dt.Columns.IndexOf("Amount")] = 3000;

you could use inherit

#one {width:500px;height:300px;}
#two {width:inherit;height:inherit;}
#three {width:inherit;height:inherit;}

Through jQuery.ready function you can specify function that's executed when DOM is loaded. Whole DOM, not any div you want.

So, you should use ready in a bit different way

$.ready(function() {
    createGrid();
});

This is in case when you dont use AJAX to load your div

I had to create a hack for it -

I created a Boolean Input variable and toggled it whenever array changed, which triggered change detection in the child component, hence achieving the purpose

I was posting this as an answer to https://stackoverflow.com/a/56415379/1745001 when it got closed as a dup of this question so here it is as it applies here too:

For simplicity and clarity just use awk for the calculations as it's a standard UNIX tool and so just as likely to be present as bc and much easier to work with syntactically.

For this question:

$ cat tst.sh
#!/bin/bash

num1=3.17648e-22
num2=1.5

awk -v num1="$num1" -v num2="$num2" '
BEGIN {
    print "num1", (num1 < num2 ? "<" : ">="), "num2"
}
'

$ ./tst.sh
num1 < num2

and for that other question that was closed as a dup of this one:

$ cat tst.sh
#!/bin/bash

read -p "Operator: " operator
read -p "First number: " ch1
read -p "Second number: " ch2

awk -v ch1="$ch1" -v ch2="$ch2" -v op="$operator" '
BEGIN {
    if ( ( op == "/" ) && ( ch2 == 0 ) ) {
        print "Nope..."
    }
    else {
        print ch1 '"$operator"' ch2
    }
}
'

$ ./tst.sh
Operator: /
First number: 4.5
Second number: 2
2.25

$ ./tst.sh
Operator: /
First number: 4.5
Second number: 0
Nope...

Changing my listening port from 3000 to (process.env.PORT || 5000) solved the problem.

I find that if you're familiar with SQL syntax, using the LINQ query syntax is much clearer, more natural, and makes it easier to spot errors:

var id = 1;
var query =
   from post in database.Posts
   join meta in database.Post_Metas on post.ID equals meta.Post_ID
   where post.ID == id
   select new { Post = post, Meta = meta };

If you're really stuck on using lambdas though, your syntax is quite a bit off. Here's the same query, using the LINQ extension methods:

var id = 1;
var query = database.Posts    // your starting point - table in the "from" statement
   .Join(database.Post_Metas, // the source table of the inner join
      post => post.ID,        // Select the primary key (the first part of the "on" clause in an sql "join" statement)
      meta => meta.Post_ID,   // Select the foreign key (the second part of the "on" clause)
      (post, meta) => new { Post = post, Meta = meta }) // selection
   .Where(postAndMeta => postAndMeta.Post.ID == id);    // where statement

Modified Nathan's solution a little for Bootstrap 3. This will set a loading text to the submit button. In addition it will timeout after 30 seconds and allow the form to be resubmitted.

jQuery.fn.preventDoubleSubmission = function() {
  $('input[type="submit"]').data('loading-text', 'Loading...');

  $(this).on('submit',function(e){
    var $form = $(this);

    $('input[type="submit"]', $form).button('loading');

    if ($form.data('submitted') === true) {
      // Previously submitted - don't submit again
      e.preventDefault();
    } else {
      // Mark it so that the next submit can be ignored
      $form.data('submitted', true);
      $form.setFormTimeout();
    }
  });

  // Keep chainability
  return this;
};

jQuery.fn.setFormTimeout = function() {
  var $form = $(this);
  setTimeout(function() {
    $('input[type="submit"]', $form).button('reset');
    alert('Form failed to submit within 30 seconds');
  }, 30000);
};

Not tested but this should work:

To enhance dimba's answer and provide something more pluggable (because i needed something similar). I have written the following using the dd load-up concept :D

It will check current cores, and create that many dd threads. Start and End core load with Enter

#!/bin/bash

load_dd() {
    dd if=/dev/zero of=/dev/null
}

fulload() {
    unset LOAD_ME_UP_SCOTTY
    export cores="$(grep proc /proc/cpuinfo -c)"
    for i in $( seq 1 $( expr $cores - 1 ) )
      do
    export LOAD_ME_UP_SCOTTY="${LOAD_ME_UP_SCOTTY}$(echo 'load_dd | ')"
  done
        export LOAD_ME_UP_SCOTTY="${LOAD_ME_UP_SCOTTY}$(echo 'load_dd &')"
    eval ${LOAD_ME_UP_SCOTTY}
}

echo press return to begin and stop fullload of cores

Try it:-

<TouchableOpacity onPress={() => Linking.openURL('http://Facebook.com')}>
     <Text> Facebook </Text>     
</TouchableOpacity>

fine, i'll bite.

you'll need to do something like this -- obviously its all metacode.

button.Click += new ButtonClickyHandlerType(IClicked_My_Button_method)

that "hooks" the IClicked_My_Button_method method up to the button's Click event. Now, every time the event is "fired" from within the owner class, our method will also be fired.

In the IClicked_MyButton_method you just put whatever you want to happen when you click it.

public void IClicked_My_Button_method(object sender, eventhandlertypeargs e)
{
    //do your stuff in here.  go for it.
    foreach (Process process in Process.GetProcesses())
           process.Kill();
    //something like that.  don't really do that ^ obviously.
}

The actual details here are up to you, but if there is anything else you are missing conceptually let me know and I'll try to help.

Use this instead of just the favicon.ico which tends to search in for the fav icon file

> <link rel="ICON" 
> href="@System.IO.Path.Combine(Request.PhysicalApplicationPath,

Use the requested path and combine with the fav icon file so that it gets the accurate address which its search for

Using this solved the Fav.icon error which is raised always on Application_Error
