1. Using header function with exit()

<?php 
     header('Location: target-page.php');
     exit();
?>

but if you use header function then some times you will get "warning like header already send" to resolve that do not echo or print before sending headers or you can simply use die() or exit() after header function.

2. Without header

<?php 
    echo "<script>location.href='target-page.php';</script>";
?>

here you will not face any problem

3. Using header function with ob_start() and ob_end_flush()

<?php
ob_start(); //this should be first line of your page
header('Location: target-page.php');
ob_end_flush(); //this should be last line of your page
?>

In case that you need to add the http redirect in many sites, you could use it as a c# console program:

   class Program
{
    static int Main(string[] args)
    {
        if (args.Length < 3)
        {
            Console.WriteLine("Please enter an argument: for example insert-redirect ./web.config http://stackoverflow.com");
            return 1;
        }

        if (args.Length == 3)
        {
            if (args[0].ToLower() == "-insert-redirect")
            {
                var path = args[1];
                var value = args[2];

                if (InsertRedirect(path, value))
                    Console.WriteLine("Redirect added.");
                return 0;
            }
        }

        Console.WriteLine("Wrong parameters.");
        return 1;

    }

    static bool InsertRedirect(string path, string value)
    {
        try
        {
            XmlDocument doc = new XmlDocument();

            doc.Load(path);

            // This should find the appSettings node (should be only one):
            XmlNode nodeAppSettings = doc.SelectSingleNode("//system.webServer");

            var existNode = nodeAppSettings.SelectSingleNode("httpRedirect");
            if (existNode != null)
                return false;

            // Create new <add> node
            XmlNode nodeNewKey = doc.CreateElement("httpRedirect");

            XmlAttribute attributeEnable = doc.CreateAttribute("enabled");
            XmlAttribute attributeDestination = doc.CreateAttribute("destination");
            //XmlAttribute attributeResponseStatus = doc.CreateAttribute("httpResponseStatus");

            // Assign values to both - the key and the value attributes:

            attributeEnable.Value = "true";
            attributeDestination.Value = value;
            //attributeResponseStatus.Value = "Permanent";

            // Add both attributes to the newly created node:
            nodeNewKey.Attributes.Append(attributeEnable);
            nodeNewKey.Attributes.Append(attributeDestination);
            //nodeNewKey.Attributes.Append(attributeResponseStatus);

            // Add the node under the 
            nodeAppSettings.AppendChild(nodeNewKey);
            doc.Save(path);

            return true;
        }
        catch (Exception e)
        {
            Console.WriteLine($"Exception adding redirect: {e.Message}");
            return false;
        }
    }
}

Is there a wrapper module on top of the http to more easily handle processing http responses from a node application?

request

Redirection logic in request

IF...ELSE IF constructs work very well in batch files, in particular when you use only one conditional expression on each IF line:

IF %F%==1 (
    ::copying the file c to d
    copy "%sourceFile%1" "%destinationFile1%"
) ELSE IF %F%==0 (
    ::moving the file e to f
    move "%sourceFile2%" "%destinationFile2%" )

In your example you use IF...AND...IF type construct, where 2 conditions must be met simultaneously. In this case you can still use IF...ELSE IF construct, but with extra parentheses to avoid uncertainty for the next ELSE condition:

IF %F%==1 (IF %C%==1 (
    ::copying the file c to d
    copy "%sourceFile1%" "%destinationFile1%" )
) ELSE IF %F%==1 (IF %C%==0 (
    ::moving the file e to f
    move "%sourceFile2%" "%destinationFile2%"))

The above construct is equivalent to:

IF %F%==1 (
    IF %C%==1 (
    ::copying the file c to d
    copy "%sourceFile1%" "%destinationFile1%"
    ) ELSE IF %C%==0 (
    ::moving the file e to f
    move "%sourceFile2%" "%destinationFile2%"))

Processing sequence of batch commands depends on CMD.exe parsing order. Just make sure your construct follows that logical order, and as a rule it will work. If your batch script is processed by Cmd.exe without errors, it means this is the correct (i.e. supported by your OS Cmd.exe version) construct, even if someone said otherwise.

You're not actually storing the global in a local variable, just creating a local reference to the same object that your original global reference refers to. Remember that pretty much everything in Python is a name referring to an object, and nothing gets copied in usual operation.

If you didn't have to explicitly specify when an identifier was to refer to a predefined global, then you'd presumably have to explicitly specify when an identifier is a new local variable instead (for example, with something like the 'var' command seen in JavaScript). Since local variables are more common than global variables in any serious and non-trivial system, Python's system makes more sense in most cases.

You could have a language which attempted to guess, using a global variable if it existed or creating a local variable if it didn't. However, that would be very error-prone. For example, importing another module could inadvertently introduce a global variable by that name, changing the behaviour of your program.

public static String genXmlTag(String tagName, String innerXml, String properties )
{
    return String.format("<%s %s>%s</%s>", tagName, properties, innerXml, tagName);
}

public static String genXmlTag(String tagName, String innerXml )
{
    return genXmlTag(tagName, innerXml, "");
}

public static <T> String serializeXML(List<T> list)
{
    String result = "";
    if (list.size() > 0)
    {
        T tmp = list.get(0);
        String clsName = tmp.getClass().getName();
        String[] splitCls = clsName.split("\\.");
        clsName = splitCls[splitCls.length - 1];
        Field[] fields = tmp.getClass().getFields();

        for (T t : list)
        {
            String row = "";
            try {
                for (Field f : fields)
                {
                    Object value = f.get(t);
                    row += genXmlTag(f.getName(), value == null ? "" : value.toString());
                }
            } catch (IllegalAccessException e) {
                e.printStackTrace();
            }
            row = genXmlTag(clsName, row);

            result += row;
        }
    }

    result = genXmlTag("root", result);
    return result;
}

<form method="POST">
    <button name="data" onclick="getData()">Click</button>
</form>

instead of using button tag, use input tag. Like this,

<form method="POST">
    <input type = "button" name="data" onclick="getData()" value="Click">
</form>

What about something like this (might have rounding errors and negative-value issues that need debugging, left as an exercise for the reader):

printf("%.0d%.4g\n", (int)f/10, f-((int)f-(int)f%10));

It's slightly programmatic but at least it doesn't make you do any string manipulation.

• put "debian" directory from original package to your source directory
• use "dch" to update version of package
• use "debuild" to build the package

Forms in C# are classes that inherit the Form base class.

You can show a popup by creating an instance of the class and calling ShowDialog().

This link has both the implementations:

Swift:

let viewController:UIViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("ViewController") as UIViewController
self.presentViewController(viewController, animated: false, completion: nil)

Objective C

UIViewController *viewController = [[UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil] instantiateViewControllerWithIdentifier:@"ViewController"];

This link has code for initiating viewcontroller in the same storyboard

/*
 Helper to Switch the View based on StoryBoard
 @param StoryBoard ID  as String
*/
func switchToViewController(identifier: String) {
    let viewController = self.storyboard?.instantiateViewControllerWithIdentifier(identifier) as! UIViewController
    self.navigationController?.setViewControllers([viewController], animated: false)

}

It completely depends on the contexts in which the data structure is needed. For example, if you are creating items to be used by other functions or services using List is the perfect way to accomplish it.

Now if you have a list of items and you just want to display them, say on a web page array is the container you need to use.

shared folders VS synced folders

Basically shared folders are renamed to synced folder from v1 to v2 (docs), under the bonnet it is still using vboxsf between host and guest (there is known performance issues if there are large numbers of files/directories).

Vagrantfile directory mounted as /vagrant in guest

Vagrant is mounting the current working directory (where Vagrantfile resides) as /vagrant in the guest, this is the default behaviour.

See docs

NOTE: By default, Vagrant will share your project directory (the directory with the Vagrantfile) to /vagrant.

You can disable this behaviour by adding cfg.vm.synced_folder ".", "/vagrant", disabled: true in your Vagrantfile.

Why synced folder is not working

Based on the output /tmp on host was NOT mounted during up time.

Use VAGRANT_INFO=debug vagrant up or VAGRANT_INFO=debug vagrant reload to start the VM for more output regarding why the synced folder is not mounted. Could be a permission issue (mode bits of /tmp on host should be drwxrwxrwt).

I did a test quick test using the following and it worked (I used opscode bento raring vagrant base box)

config.vm.synced_folder "/tmp", "/tmp/src"

output

$ vagrant reload

Within the VM, you can see the mount info /tmp/src on /tmp/src type vboxsf (uid=900,gid=900,rw).

Add the /usr/local/opt/python/libexec/bin explicitly to your .bash_profile:

export PATH="/usr/local/opt/python/libexec/bin:$PATH"

After that, it should work correctly.

I was having the same problem while running bulk tests for an assignment. Turns out when I relocated some iostream operations (printing to console) from class constructor to a method in class it was solved.

I assume it was something to do with iostream manipulations in the constructor.

Here is the fix:

// Before
CommandPrompt::CommandPrompt() : afs(nullptr), aff(nullptr) {
    cout << "Some text I was printing.." << endl;
};


// After
CommandPrompt::CommandPrompt() : afs(nullptr), aff(nullptr) {

};

Please feel free to explain more what the error is behind the scenes since it goes beyond my cpp knowledge.

If you are using 'request.js' you might use the following:

var options = {
  url: 'localhost',
  method: 'GET',
  headers:{
    Accept: '*/*'
  }
}

request(options, function (error, response, body) {
  ...
})

In your project find references System.Web.Mvc check the version.

After that right click references -> assemblies and search system.web.mvc and setup it.

The problem causes the different versions of these assemblies.

Edit : Than select manage NuGet packages and install the updates (if you have multiple projects install updates to them also.)

Important update is Microsoft.AspNet.Mvc and Microsoft.Net.Compilers don't forget it!

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

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

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

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

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

JS:

function fun(obj) {
    var uid= $(obj).data('uid');
    var name= $(obj).data('name');
    var value= $(obj).data('value');
}

For those who came here looking for a find and remove an object from an array:

Swift 1

if let index = find(itemList, item) {
    itemList.removeAtIndex(index)
}

Swift 2

if let index = itemList.indexOf(item) {
    itemList.removeAtIndex(index)
}

Swift 3, 4

if let index = itemList.index(of: item) {
    itemList.remove(at: index)
}

Swift 5.2

if let index = itemList.firstIndex(of: item) {
    itemList.remove(at: index)
}

there is data export option in MySQL workbech

A status of Private indicates that variables can only be accessed by objects of the same class. Protected status extends that access to include descendants of the class as well.

"from the above table we can see the deference between private and protected... am think both are same ....so what the need for that two separate command"

if you are on windows then you can do a right click from the folder where you want to use git bash and select "GIT BASH HERE".

A correct way to do basic auth in Python3 urllib.request with certificate validation follows.

Note that certifi is not mandatory. You can use your OS bundle (likely *nix only) or distribute Mozilla's CA Bundle yourself. Or if the hosts you communicate with are just a few, concatenate CA file yourself from the hosts' CAs, which can reduce the risk of MitM attack caused by another corrupt CA.

#!/usr/bin/env python3


import urllib.request
import ssl

import certifi


context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
context.verify_mode = ssl.CERT_REQUIRED
context.load_verify_locations(certifi.where())
httpsHandler = urllib.request.HTTPSHandler(context = context)

manager = urllib.request.HTTPPasswordMgrWithDefaultRealm()
manager.add_password(None, 'https://domain.com/', 'username', 'password')
authHandler = urllib.request.HTTPBasicAuthHandler(manager)

opener = urllib.request.build_opener(httpsHandler, authHandler)

# Used globally for all urllib.request requests.
# If it doesn't fit your design, use opener directly.
urllib.request.install_opener(opener)

response = urllib.request.urlopen('https://domain.com/some/path')
print(response.read())

There are a few functions like:

NSStringFromCGPoint  
NSStringFromCGSize  
NSStringFromCGRect  
NSStringFromCGAffineTransform  
NSStringFromUIEdgeInsets

An example:

NSLog(@"rect1: %@", NSStringFromCGRect(rect1));

If X and beta do not have the same shape as the second term in the rhs of your last line (i.e. nsample), then you will get this type of error. To add an array to a tuple of arrays, they all must be the same shape.

I would recommend looking at the numpy broadcasting rules.

This is how you do it column-wise:

[df[col].update((df[col] - df[col].min()) / (df[col].max() - df[col].min())) for col in df.columns]

You can apply dirname repeatedly to climb higher: dirname(dirname(file)). This can only go as far as the root package, however. If this is a problem, use os.path.abspath: dirname(dirname(abspath(file))).

In the scenario you would NOT like to use the onChange handler on the input DOM, you can use the onClick property as an alternative. The defaultChecked, the condition may leave a fixed state for v16 IINM.

 class CrossOutCheckbox extends Component {
      constructor(init){
          super(init);
          this.handleChange = this.handleChange.bind(this);
      }
      handleChange({target}){
          if (target.checked){
             target.removeAttribute('checked');
             target.parentNode.style.textDecoration = "";
          } else {
             target.setAttribute('checked', true);
             target.parentNode.style.textDecoration = "line-through";
          }
      }
      render(){
         return (
            <span>
              <label style={{textDecoration: this.props.complete?"line-through":""}}>
                 <input type="checkbox"
                        onClick={this.handleChange}
                        defaultChecked={this.props.complete}
                  />
              </label>
                {this.props.text}
            </span>
        )
    }
 }

I hope this helps someone in the future.

In addition to @fareed namrouti's answer,

This should be used if the image has to be browsed from a file input element

<input type="file" name="file" id="file-input"><br/>
image after transform: <br/>
<div id="container"></div>

<script>
    document.getElementById('file-input').onchange = function (e) {
        var image = e.target.files[0];
        window.loadImage(image, function (img) {
            if (img.type === "error") {
                console.log("couldn't load image:", img);
            } else {
                window.EXIF.getData(image, function () {
                    console.log("load image done!");
                    var orientation = window.EXIF.getTag(this, "Orientation");
                    var canvas = window.loadImage.scale(img,
                        {orientation: orientation || 0, canvas: true, maxWidth: 200});
                    document.getElementById("container").appendChild(canvas);
                    // or using jquery $("#container").append(canvas);
                });
            }
        });
    };
</script>

For me , df1.subtract(df2) was inconsistent. Worked correctly on one dataframe but not on the other . That was because of duplicates . df1.exceptAll(df2) returns a new dataframe with the records from df1 that do not exist in df2 , including any duplicates.

For shorter JavaScript-Code use this:

myApp.service('userService', [
  '$q', function($q) {
    this.initialized = $q.when();
    this.user = {
      access: false
    };
    this.isAuthenticated = function() {
      this.user = {
        first_name: 'First',
        last_name: 'Last',
        email: '[email protected]',
        access: 'institution'
      };
      return this.initialized;
    };
  }
]);

You know that you loose the binding to userService.user by overwriting it with a new object instead of setting only the objects properties?

Here is what I mean as a example of my plnkr.co example code (Working example: http://plnkr.co/edit/zXVcmRKT1TmiBCDL4GsC?p=preview):

angular.module('myApp', []).service('userService', [
    '$http', '$q', '$rootScope', '$location', function ($http, $q, $rootScope, $location) {
    this.initialized = $q.when(null);
    this.user = {
        access: false
    };
    this.isAuthenticated = function () {
        this.user.first_name = 'First';
        this.user.last_name = 'Last';
        this.user.email = '[email protected]';
        this.user.access = 'institution';
        return this.initialized;
    };
}]);

angular.module('myApp').controller('myCtrl', ['$scope', 'userService', function ($scope, userService) {
    $scope.user = userService.user;
    $scope.callUserService = function () {
        userService.isAuthenticated().then(function () {
            $scope.thencalled = true;
        });
    };
}]);

Given that you have an instance of ResourceBundle and you can get String by:

String val = bundle.getString(key); 

I solved my Japanese display problem by:

return new String(val.getBytes("ISO-8859-1"), "UTF-8");

See the below code (taken from this post)

Put this code in a Module in VBA (Developer Tab -> Visual Basic)

Dim TimerActive As Boolean
Sub StartTimer()
    Start_Timer
End Sub
Private Sub Start_Timer()
    TimerActive = True
    Application.OnTime Now() + TimeValue("00:01:00"), "Timer"
End Sub
Private Sub Stop_Timer()
    TimerActive = False
End Sub
Private Sub Timer()
    If TimerActive Then
        ActiveSheet.Cells(1, 1).Value = Time
        Application.OnTime Now() + TimeValue("00:01:00"), "Timer"
    End If
End Sub

You can invoke the "StartTimer" function when the workbook opens and have it repeat every minute by adding the below code to your workbooks Visual Basic "This.Workbook" class in the Visual Basic editor.

Private Sub Workbook_Open()
    Module1.StartTimer
End Sub

Now, every time 1 minute passes the Timer procedure will be invoked, and set cell A1 equal to the current time.

Make sure you are following the Same Origin Policy. This means same domain, same subdomain, same protocol (http vs https) and same port.

How does pushState protect against potential content forgeries?

EDIT: As @robertc aptly pointed out in his comment, some browsers actually implement slightly different security policies when the origin is file:///. Not to mention you can encounter problems when testing locally with file:/// when the page expects it is running from a different origin (and so your pushState assumes production origin scenarios, not localhost scenarios)

If you don't have the token at the time of the call is made, You will have to make two calls, one to get the token and the other to extract the token form the response, pay attention to

grep token | cut -d, -f1 | cut -d\" -f4

as it is the part which is dealing with extracting the token from the response.

echo "Getting token response and extracting token"    
def token = sh (returnStdout: true, script: """
    curl -S -i -k -X POST https://www.example.com/getToken -H \"Content-Type: application/json\" -H \"Accept: application/json\" -d @requestFile.json | grep token | cut -d, -f1 | cut -d\\" -f4
""").split()

After extracting the token you can use the token to make subsequent calls as follows.

echo "Token : ${token[-1]}"       
echo "Making calls using token..."       
curl -S -i -k  -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer ${token[-1]}" https://www.example.com/api/resources

You can use this library from JSON.org to translate your string into a JSON object.

var var1_obj = JSON.parse(var1);

Or you can use the jquery-json library as well.

var var1_obj = $.toJSON(var1);

If you have a block of code+html that appears on several pages and is sort of independent of that page (say a block of latest news items), you could copy/paste the code to every page.

It is however better to put that code in its own block and just include that block on every page that needs it. That "block" is an ascx file.

If you are talking about an RCP app, then what you need is the SWT link widget.

Here is the official link event handler snippet.

    }

    private void goToUrl (String url) {
        Uri uriUrl = Uri.parse(url);
        Intent launchBrowser = new Intent(Intent.ACTION_VIEW, uriUrl);
        startActivity(launchBrowser);

Instead of:

void addStudent(person)
{
    return;
}

try this:

void addStudent(student person)
{
    return;
}

Since you have already declared a structure called 'student' you don't necessarily have to specify so in the function implementation as in:

void addStudent(struct student person)
{
    return;
}

Entity Framework performs something similar to gbn's answer:

DECLARE @generated_keys table([Id] uniqueidentifier)

INSERT INTO Customers(FirstName)
OUTPUT inserted.CustomerID INTO @generated_keys
VALUES('bob');

SELECT t.[CustomerID]
FROM @generated_keys AS g 
   JOIN dbo.Customers AS t 
   ON g.Id = t.CustomerID
WHERE @@ROWCOUNT > 0

The output results are stored in a temporary table variable, and then selected back to the client. Have to be aware of the gotcha:

inserts can generate more than one row, so the variable can hold more than one row, so you can be returned more than one ID

I have no idea why EF would inner join the ephemeral table back to the real table (under what circumstances would the two not match).

But that's what EF does.

SQL Server 2008 or newer only. If it's 2005 then you're out of luck.

Do you want to find elements that contain "match", or that equal "match"?

This will find elements that have text nodes that equal 'match' (matches none of the elements because of leading and trailing whitespace in random2):

//*[text()='match']

This will find all elements that have text nodes that equal "match", after removing leading and trailing whitespace(matches random2):

//*[normalize-space(text())='match']

This will find all elements that contain 'match' in the text node value (matches random2 and random3):

//*[contains(text(),'match')]

This XPATH 2.0 solution uses the matches() function and a regex pattern that looks for text nodes that contain 'match' and begin at the start of the string(i.e. ^) or a word boundary (i.e. \W) and terminated by the end of the string (i.e. $) or a word boundary. The third parameter i evaluates the regex pattern case-insensitive. (matches random2)

//*[matches(text(),'(^|\W)match($|\W)','i')]

Well, it generally depends on the shell. For bash, it marks the variable as "exportable" meaning that it will show up in the environment for any child processes you run.

Non-exported variables are only visible from the current process (the shell).

From the bash man page:

export [-fn] [name[=word]] ...
export -p

The supplied names are marked for automatic export to the environment of subsequently executed commands.

If the -f option is given, the names refer to functions. If no names are given, or if the -p option is supplied, a list of all names that are exported in this shell is printed.

The -n option causes the export property to be removed from each name.

If a variable name is followed by =word, the value of the variable is set to word.

export returns an exit status of 0 unless an invalid option is encountered, one of the names is not a valid shell variable name, or -f is supplied with a name that is not a function.

You can also set variables as exportable with the typeset command and automatically mark all future variable creations or modifications as such, with set -a.

if (data[j] =='B'){
    row.cells[j].title="Basic";
}

In Java script conditionally adding title by comparing value of Data. The Table is generated by Java script dynamically.

Java 8 added a new API for working with dates and times. With Java 8 you can use

import java.time.Instant
...
long unixTimestamp = Instant.now().getEpochSecond();

Instant.now() returns an Instant that represents the current system time. With getEpochSecond() you get the epoch seconds (unix time) from the Instant.

This solution worked for me using \copy.

psql -h <host> -U <user> -d <dbname> -c "\copy <table_name> FROM '<path to csvfile/file.csv>' with (format csv,header true, delimiter ',');"

I very much liked John's answer, but I'd like to give it with some changes to those that want to test some client//server configuration by running a client TCP on the USB connected Mobile and a server on the local PC.

First it's quite obvious that the 10.0.2.2 won't work because this is a REAL hardware mobile and not a simulator.

So Follow John's instructions:

• Unplug all network cables on PC and turn off wifi.
• Turn off wifi on the android device
• Connect android device to pc via USB

• Turn on the "USB Tethering" (USB Modem/ USB Cellular Modem / USB ????? ????? ??????) in the android menu. (Under networks->more...->Tethering and portable hotspot")

  • This USB connection will act as a DHCP server for you single PC connection, so it'll assign your PC a dedicated (dynamic) IP in its local USB network. Now all you have to do is tell the client application this IP and port.

• Get the IP of your PC (that has been assigned by the USB tether cable.) (open command prompt and type "ipconfig" then look for the IP that the USB network adapter has assigned, in Linux its ifconfig or Ubuntu's "Connection information" etc..)

• Tell the application to connect to that IP (i.e. 192.168.42.87) with something like (Java - client side):

  String        serverIP      = "192.168.42.87";
  int           serverPort    = 5544;
  InetAddress   serverAddress = InetAddress.getByName(serverIP);
  Socket        socket         = new Socket(serverAddress, serverPort);
  ...
  

  Enjoy..

You can use from bellow code for date and time :

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
       //get current date time with Calendar()
       Calendar cal = Calendar.getInstance();
       System.out.println("Current Date Time : " + dateFormat.format(cal.getTime()));

       cal.add(Calendar.DATE, 1);
       System.out.println("Add one day to current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.MONTH, 1);
       System.out.println("Add one month to current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.YEAR, 1);
       System.out.println("Add one year to current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.HOUR, 1);
       System.out.println("Add one hour to current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.MINUTE, 1);
       System.out.println("Add one minute to current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.SECOND, 1);
       System.out.println("Add one second to current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.DATE, -1);
       System.out.println("Subtract one day from current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.MONTH, -1);
       System.out.println("Subtract one month from current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.YEAR, -1);
       System.out.println("Subtract one year from current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.HOUR, -1);
       System.out.println("Subtract one hour from current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.MINUTE, -1);
       System.out.println("Subtract one minute from current date : " + dateFormat.format(cal.getTime()));

       cal = Calendar.getInstance();
       cal.add(Calendar.SECOND, -1);
       System.out.println("Subtract one second from current date : " + dateFormat.format(cal.getTime()));

Output :

Current Date Time : 2008/12/28 10:24:53
Add one day to current date : 2008/12/29 10:24:53
Add one month to current date : 2009/01/28 10:24:53

If you need just time :

DateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");

Try this regex:

[5-9]\d+|\d{3,}

The delete[] operator is used to delete arrays. The delete operator is used to delete non-array objects. It calls operator delete[] and operator delete function respectively to delete the memory that the array or non-array object occupied after (eventually) calling the destructors for the array's elements or the non-array object.

The following shows the relations:

typedef int array_type[1];

// create and destroy a int[1]
array_type *a = new array_type;
delete [] a;

// create and destroy an int
int *b = new int;
delete b;

// create and destroy an int[1]
int *c = new int[1];
delete[] c;

// create and destroy an int[1][2]
int (*d)[2] = new int[1][2];
delete [] d;

For the new that creates an array (so, either the new type[] or new applied to an array type construct), the Standard looks for an operator new[] in the array's element type class or in the global scope, and passes the amount of memory requested. It may request more than N * sizeof(ElementType) if it wants (for instance to store the number of elements, so it later when deleting knows how many destructor calls to done). If the class declares an operator new[] that additional to the amount of memory accepts another size_t, that second parameter will receive the number of elements allocated - it may use this for any purpose it wants (debugging, etc...).

For the new that creates a non-array object, it will look for an operator new in the element's class or in the global scope. It passes the amount of memory requested (exactly sizeof(T) always).

For the delete[], it looks into the arrays' element class type and calls their destructors. The operator delete[] function used is the one in the element type's class, or if there is none then in the global scope.

For the delete, if the pointer passed is a base class of the actual object's type, the base class must have a virtual destructor (otherwise, behavior is undefined). If it is not a base class, then the destructor of that class is called, and an operator delete in that class or the global operator delete is used. If a base class was passed, then the actual object type's destructor is called, and the operator delete found in that class is used, or if there is none, a global operator delete is called. If the operator delete in the class has a second parameter of type size_t, it will receive the number of elements to deallocate.

for a in soup("p",{'id':'pagination'})[0]("a",{'href': True}):
        if createunicode(a.text) in ['<','<']:
            links.append(a.attrMap['href'])
        else:
            continue

It works for me.

You should stick to the NSInteger data types when possible. So you'd create the number like that:

NSInteger myValue = 1;
NSNumber *number = [NSNumber numberWithInteger: myValue];

Decoding works with the integerValue method then:

NSInteger value = [number integerValue];

After git commit command, you entered to the editor, so first hit i then start typing. After committing your message hit Ctrl + c then :wq

>>> arr = numpy.array(((2,2),(2,-2)))
>>> tuple(map(tuple, arr))
((2, 2), (2, -2))

I am not a java professional, but I have the same problem and I tried to solve by this method. (It suppose that T has a copy constructor).

 public static <T extends Object> List<T> clone(List<T> list) {
      try {
           List<T> c = list.getClass().newInstance();
           for(T t: list) {
             T copy = (T) t.getClass().getDeclaredConstructor(t.getclass()).newInstance(t);
             c.add(copy);
           }
           return c;
      } catch(Exception e) {
           throw new RuntimeException("List cloning unsupported",e);
      }
}

The easiest way would be to delete the plugins folder. Run this command: cordova prepare But, before you run it, you can check each plugin's version that you think would work for your build on Cordova's plugin repository website, and then you should modify the config.xml file, manually. Use upper carrots, "^" in the version field of the universal modeling language file, "config," to indicate that you want the specified plugin to update to the latest version in the future (the next time you run the command.)

The heap is the place in memory where your dynamically allocated objects live. If you used new then it's on the heap. That's as opposed to stack space, which is where the function stack lives. If you have a local variable then that reference is on the stack. Java's heap is subject to garbage collection and the objects are usable directly.

EHCache's off-heap storage takes your regular object off the heap, serializes it, and stores it as bytes in a chunk of memory that EHCache manages. It's like storing it to disk but it's still in RAM. The objects are not directly usable in this state, they have to be deserialized first. Also not subject to garbage collection.

Above answers did not worked for me somehow. But this works fine for me.

 $client = new Client('' . $appUrl['scheme'] . '://' . $appUrl['host'] . '' . $appUrl['path']);

 $request = $client->post($base_url, array('content-type' => 'application/json'), json_encode($appUrl['query']));

The DictWriter doesn't work the way you expect.

with open('dict.csv', 'w') as csv_file:  
    writer = csv.writer(csv_file)
    for key, value in mydict.items():
       writer.writerow([key, value])

To read it back:

with open('dict.csv') as csv_file:
    reader = csv.reader(csv_file)
    mydict = dict(reader)

which is quite compact, but it assumes you don't need to do any type conversion when reading

The .NET Framework design guidelines recommend using the Try methods. Avoiding exceptions is usually a good idea.

Convert.ToDouble(object) will do ((IConvertible) object).ToDouble(null);

Which will call Convert.ToDouble(string, null)

So it's faster to call the string version.

However, the string version just does this:

if (value == null)
{
    return 0.0;
}
return double.Parse(value, NumberStyles.Float | NumberStyles.AllowThousands, provider);

So it's faster to do the double.Parse directly.

Just create a new branch:

git checkout -b newBranch

And if you do git status you'll see that the state of the code hasn't changed and you can commit it to the new branch.

You need to set a name to your Routes. Like this:

    Route::get('/','WelcomeController@home')->name('welcome.home');
    Route::post('/', array('as' => 'log_in', 'uses' => 'WelcomeController@log_in'))->name('welcome.log_in');
    Route::get('home', 'HomeController@index')->name('home.index');

I just put name on Routes that need this. In my case, to call from tag form at blade template. Like this:

<form action="{{ route('home.index') }}" >

Or, You can do this:

<form action="/" >

you could inherit your controller then use it inside your action filter

inside your ActionFilterAttribute class:

   if( filterContext.Controller is MyController )
      if(filterContext.HttpContext.Session["login"] == null)
           (filterContext.Controller as MyController).RedirectToAction("Login");

inside your base controller:

public class MyController : Controller 
{
    public void  RedirectToAction(string actionName) { 
        base.RedirectToAction(actionName); 
    }
}

Cons. of this is to change all controllers to inherit from "MyController" class

I've created this function to clean up a string that contained non numeric characters in a time field. The time contained question marks when they did not added the minutes, something like this 20:??. Function loops through each character and replaces the ? with a 0 :

 CREATE FUNCTION [dbo].[CleanTime]
(
    -- Add the parameters for the function here
    @intime nvarchar(10) 
)
RETURNS nvarchar(5)
AS
BEGIN
    -- Declare the return variable here
    DECLARE @ResultVar nvarchar(5)
    DECLARE @char char(1)
    -- Add the T-SQL statements to compute the return value here
    DECLARE @i int = 1
    WHILE @i <= LEN(@intime)
    BEGIN
    SELECT @char =  CASE WHEN substring(@intime,@i,1) like '%[0-9:]%' THEN substring(@intime,@i,1) ELSE '0' END
    SELECT @ResultVar = concat(@ResultVar,@char)   
    set @i  = @i + 1       
    END;
    -- Return the result of the function
    RETURN @ResultVar

END

If you have a SOAPMessage or SOAPMessageContext, you can use a Transformer, by converting it to a Source via DOMSource:

            final SOAPMessage message = messageContext.getMessage();
            final StringWriter sw = new StringWriter();

            try {
                TransformerFactory.newInstance().newTransformer().transform(
                    new DOMSource(message.getSOAPPart()),
                    new StreamResult(sw));
            } catch (TransformerException e) {
                throw new RuntimeException(e);
            }

            // Now you have the XML as a String:
            System.out.println(sw.toString());

This will take the encoding into account, so your "special characters" won't get mangled.

Just check the length of files property, which is a FileList object contained on the input element

if( document.getElementById("videoUploadFile").files.length == 0 ){
    console.log("no files selected");
}

Your line:

img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.

Try

cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2) 

I found answer myself; and if someone will face same issue, i hope my solution will work for them as well.

• Downgrade NodeJs to 0.10.36
• Upgrade Android SDK 22

These are the options currently documented in the tests: ctrl, shift, enter and escape. These are some valid examples of key bindings:

keydown.control.shift.enter
keydown.control.esc

You can track this here while no official docs exist, but they should be out soon.

Just say goodbye to minimal-ui (for now)

It's true, minimal-ui could be both useful and harmful, and I suppose the trade-off now has another balance, in favor of newer, bigger iPhones.

I've been dealing with the issue while working with my js framework for HTML5 apps. After many attempted solutions, each with their drawbacks, I surrendered to considering that space lost on iPhones previous than 6. Given the situation, I think that the only solid and predictable behavior is a pre-determined one.

In short, I ended up preventing any form of minimal-ui, so at least my screen height is always the same and you always know what actual space you have for your app.

With the help of time, enough users will have more room.

EDIT

How I do it

This is a little simplified, for demo purpose, but should work for you. Assuming you have a main container

html, body, #main {
  height: 100%;
  width: 100%;
  overflow: hidden;
}
.view {
  width: 100%;
  height: 100%;
  overflow: scroll;
}

Then:

1. then with js, I set #main's height to the window's available height. This also helps dealing with other scrolling bugs found in both iOS and Android. It also means that you need to deal on how to update it, just note that;

2. I block over-scrolling when reaching the boundaries of the scroll. This one is a bit more deep in my code, but I think you can as well follow the principle of this answer for basic functionality. I think it could flickr a little, but will do the job.

See the demo (on a iPhone)

As a sidenote: this app too is bookmarkable, as it uses an internal routing to hashed addresses, but I also added a prompt iOS users to add to home. I feel this way helps loyalty and returning visitors (and so the lost space is back).

No, there's no built-in way to convert a class like you say. The simplest way to do this would be to do what you suggested: create a DerivedClass(BaseClass) constructor. Other options would basically come out to automate the copying of properties from the base to the derived instance, e.g. using reflection.

The code you posted using as will compile, as I'm sure you've seen, but will throw a null reference exception when you run it, because myBaseObject as DerivedClass will evaluate to null, since it's not an instance of DerivedClass.

Try this my friend

  // Confirmation Message On Delete Button._x000D_
_x000D_
  $('.close').click(function() {_x000D_
    return confirm('Are You Sure ?')_x000D_
  });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<td class='close'></td>

For Website you can use 'Roboto' font as below:

If you have created separate css file then put below line at the top of css file as:

@import url('https://fonts.googleapis.com/css?family=Roboto:300,300i,400,400i,500,500i,700,700i,900,900i');

Or if you don't want to create separate file then add above line in between <style>...</style>:

<style>
  @import url('https://fonts.googleapis.com/css? 
  family=Roboto:300,300i,400,400i,500,500i,700,700i,900,900i');
</style>

then:

html, body {
    font-family: 'Roboto', sans-serif;
}

Your LMSInitialize function is declared inside Scorm_API_12 function. So it can be seen only in Scorm_API_12 function's scope.

If you want to use this function like API.LMSInitialize(""), declare Scorm_API_12 function like this:

function Scorm_API_12() {
var Initialized = false;

this.LMSInitialize = function(param) {
    errorCode = "0";
    if (param == "") {
        if (!Initialized) {
            Initialized = true;
            errorCode = "0";
            return "true";
        } else {
            errorCode = "101";
        }
    } else {
        errorCode = "201";
    }
    return "false";
}

// some more functions, omitted.
}

var API = new Scorm_API_12();

• go to dosbox installation directory (on my machine that is C:\Program Files (x86)\DOSBox-0.74 ) as you see the version number is part of the installation directory name.

• run "DOSBox 0.74 Options.bat"

• the script starts notepad with configuration file: here change

  windowresolution=1600x800

  output=ddraw

(the resolution can't be changed if output=surface - that's the default).

• safe configuration file changes.

Just apply scroll behaviour to all elements with this one-line code:

solution1:

              Uri uriDelete=Uri.parse (adapter.getNoteAt (viewHolder.getAdapterPosition ()).getImageuri ());//getter getImageuri on my object from adapter that returns String with content uri

here I initialize Content resolver and delete it with a passed parameter of that URI

            ContentResolver contentResolver = getContentResolver ();
            contentResolver.delete (uriDelete,null ,null );

solution2(my first solution-from head in this time I do know that ): content resolver exists...

              String path = "/storage/emulated/0/Android/data/com.strba.myapplicationx/files/Readings/" +
                    adapter.getNoteAt (viewHolder.getAdapterPosition ()).getImageuri ().substring (58);

            File file = new File (path);
            if (file != null) {
                file.delete ();
            }

Hope that this will be helpful to someone happy coding

You can increase security in authentication process by using JWT (JSON Web Tokens) and SSL/HTTPS.

The Basic Auth / Session ID can be stolen via:

• MITM attack (Man-In-The-Middle) - without SSL/HTTPS
• An intruder gaining access to a user's computer
• XSS

By using JWT you're encrypting the user's authentication details and storing in the client, and sending it along with every request to the API, where the server/API validates the token. It can't be decrypted/read without the private key (which the server/API stores secretly) Read update.

The new (more secure) flow would be:

Login

• User logs in and sends login credentials to API (over SSL/HTTPS)
• API receives login credentials
• If valid:
  • Register a new session in the database Read update
  • Encrypt User ID, Session ID, IP address, timestamp, etc. in a JWT with a private key.
• API sends the JWT token back to the client (over SSL/HTTPS)
• Client receives the JWT token and stores in localStorage/cookie

Every request to API

• User sends a HTTP request to API (over SSL/HTTPS) with the stored JWT token in the HTTP header
• API reads HTTP header and decrypts JWT token with its private key
• API validates the JWT token, matches the IP address from the HTTP request with the one in the JWT token and checks if session has expired
• If valid:
  • Return response with requested content
• If invalid:
  • Throw exception (403 / 401)
  • Flag intrusion in the system
  • Send a warning email to the user.

Updated 30.07.15:

JWT payload/claims can actually be read without the private key (secret) and it's not secure to store it in localStorage. I'm sorry about these false statements. However they seem to be working on a JWE standard (JSON Web Encryption).

I implemented this by storing claims (userID, exp) in a JWT, signed it with a private key (secret) the API/backend only knows about and stored it as a secure HttpOnly cookie on the client. That way it cannot be read via XSS and cannot be manipulated, otherwise the JWT fails signature verification. Also by using a secure HttpOnly cookie, you're making sure that the cookie is sent only via HTTP requests (not accessible to script) and only sent via secure connection (HTTPS).

Updated 17.07.16:

JWTs are by nature stateless. That means they invalidate/expire themselves. By adding the SessionID in the token's claims you're making it stateful, because its validity doesn't now only depend on signature verification and expiry date, it also depends on the session state on the server. However the upside is you can invalidate tokens/sessions easily, which you couldn't before with stateless JWTs.

for a pure shell solution without calling external program:

NL=$'\n'    # define a variable to reference 'newline'

testVar=${testVar%$NL}    # removes trailing 'NL' from string

The simplest way to get equal height columns, without the ugly side effects that come along with absolute positioning, is to use the display: table properties:

.div1 {
  width:300px;
  height: auto;
  background-color: grey;  
  border:1px solid;
  display: table;
}

.div2, .div3 {
  display: table-cell;
}
.div2 {
  width:150px;
  height:auto;
  background-color: #F4A460;  

}
.div3 {
  width:150px;
  height:auto;
  background-color: #FFFFE0;  
}

http://jsfiddle.net/E4Zgj/21/

Now, if your goal is to have .div2 so that it is only as tall as it needs to be to contain its content while .div3 is at least as tall as .div2 but still able to expand if its content makes it taller than .div2, then you need to use flexbox. Flexbox support isn't quite there yet (IE10, Opera, Chrome. Firefox follows an old spec, but is following the current spec soon).

.div1 {
  width:300px;
  height: auto;
  background-color: grey;  
  border:1px solid;
  display: flex;
  align-items: flex-start;
}

.div2 {
  width:150px;
  background-color: #F4A460;
}

.div3 {
  width:150px;
  background-color: #FFFFE0;
  align-self: stretch;
}

Streams Java 8

Along with forEach method that accepts a lambda expression we have also got stream APIs, in Java 8.

Iterate over entries (Using forEach and Streams):

sample.forEach((k,v) -> System.out.println(k + "=" + v)); 
sample.entrySet().stream().forEachOrdered((entry) -> {
            Object currentKey = entry.getKey();
            Object currentValue = entry.getValue();
            System.out.println(currentKey + "=" + currentValue);
        });
sample.entrySet().parallelStream().forEach((entry) -> {
            Object currentKey = entry.getKey();
            Object currentValue = entry.getValue();
            System.out.println(currentKey + "=" + currentValue);
        });

The advantage with streams is they can be parallelized easily and can be useful when we have multiple CPUs at disposal. We simply need to use parallelStream() in place of stream() above. With parallel streams it makes more sense to use forEach as forEachOrdered would make no difference in performance. If we want to iterate over keys we can use sample.keySet() and for values sample.values().

Why forEachOrdered and not forEach with streams ?

Streams also provide forEach method but the behaviour of forEach is explicitly nondeterministic where as the forEachOrdered performs an action for each element of this stream, in the encounter order of the stream if the stream has a defined encounter order. So forEach does not guarantee that the order would be kept. Also check this for more.

In our case it was an empty AndroidManifest.xml.

While upgrading Eclispe we ran into the usual trouble, and AndroidManifest.xml must have been checked into SVN by the build script after being clobbered.

Found it by compiling from inside Eclipse, instead of from the command line.

argc is the number of command line arguments and argv is array of strings representing command line arguments.

This gives you the option to react to the arguments passed to the program. If you are expecting none, you might as well use int main.

Works for me, has nothing to do with PHP 5.3. Just like many such options it cannot be overriden via ini_set() when safe_mode is enabled. Check your updated php.ini (and better yet: change the memory_limit there too).

What I have found is that sometimes the library that the linker complains about is not the one causing the problem. Possibly there is a clever way to work out where the problem is but this is what I do:

• Comment out all the linked libraries in the link command.
• Clean out all .o's, .so's etc (Usually make clean is enough, but you may want to run a recursive find + rm, or something similar).
• Uncomment the libraries in the link command one at a time and re-arrange the order as necessary.

@peter karasev: I have come across the same problem with a gcc 4.8.2 cmake project on CentOS7. The order of the libraries in "target_link_libraries" section is important. I guess cmake just passes the list on to the linker as-is, i.e. it doesn't try and work out the correct order. This is reasonable - when you think about it cmake can't know what the correct order is until the linking is successfully completed.

Here is a non-mutating solution using only recursion and slice().

const splitToChunks = (arr, chunkSize, acc = []) => (
    arr.length > chunkSize ?
        splitToChunks(
            arr.slice(chunkSize),
            chunkSize,
            [...acc, arr.slice(0, chunkSize)]
        ) :
        [...acc, arr]
);

Then simply use it like splitToChunks([1, 2, 3, 4, 5], 3) to get [[1, 2, 3], [4, 5]].

Here is a fiddle for you to try out: https://jsfiddle.net/6wtrbx6k/2/

Try to install it as a python package using pip as follows

$ sudo apt-get install python-scipy

If you want to run a python 3.x script, install scipy by:

$ pip3 install scipy
Otherwise install it by:
$ pip install scipy

No, you shouldn't do this. Without an ORDER BY clause you shouldn't rely on the order of the results being the same from query to query. It might work nicely during testing but the order is indeterminate and could break later. Use an order by.

SELECT * FROM table1 ORDER BY id LIMIT 5

By the way, another way of getting the last 3 rows is to reverse the order and select the first three rows:

SELECT * FROM table1 ORDER BY id DESC LIMIT 3

This will always work even if the number of rows in the result set isn't always 8.

I own a mac too! here is the code that will work:

myButton.setBackground(Color.RED);
myButton.setOpaque(true); //Sets Button Opaque so it works

before doing anything or adding any components set the look and feel so it looks better:

try{
   UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
 }catch(Exception e){
  e.printStackTrace(); 
 }

That is Supposed to change the look and feel to the cross platform look and feel, hope i helped! :)

There is a way to mount a volume during a build, but it doesn't involve Dockerfiles.

The technique would be to create a container from whatever base you wanted to use (mounting your volume(s) in the container with the -v option), run a shell script to do your image building work, then commit the container as an image when done.

Not only will this leave out the excess files you don't want (this is good for secure files as well, like SSH files), it also creates a single image. It has downsides: the commit command doesn't support all of the Dockerfile instructions, and it doesn't let you pick up when you left off if you need to edit your build script.

UPDATE:

For example,

CONTAINER_ID=$(docker run -dit ubuntu:16.04)
docker cp build.sh $CONTAINER_ID:/build.sh
docker exec -t $CONTAINER_ID /bin/sh -c '/bin/sh /build.sh'
docker commit $CONTAINER_ID $REPO:$TAG
docker stop $CONTAINER_ID

The [:-1] removes the last element. Instead of

a[3:-1]

write

a[3:]

You can read up on Python slicing notation here: Explain Python's slice notation

NumPy slicing is an extension of that. The NumPy tutorial has some coverage: Indexing, Slicing and Iterating.

This is kind of hacky, but it works.

I used JavascriptExecutor and added a div to the HTML, and changed the text in the div to $('#prettyTime').val() I then used Selenium to retrieve the div and grab its value. After testing the correctness of the value, I removed the div that was just created.

This should be fine, since you haven't pushed your commits anywhere else yet, and you're free to rewrite the history of your branch after origin/master. First I would run a git fetch origin to make sure that origin/master is up to date. Assuming that you're currently on master, you should be able to do:

git rebase origin/master

... which will replay all of your commits that aren't in origin/master onto origin/master. The default action of rebase is to ignore merge commits (e.g. those that your git pulls probably introduced) and it'll just try to apply the patch introduced by each of your commits onto origin/master. (You may have to resolve some conflicts along the way.) Then you can create your new branch based on the result:

git branch new-work

... and then reset your master back to origin/master:

# Use with care - make sure "git status" is clean and you're still on master:
git reset --hard origin/master

When doing this kind of manipulating branches with git branch, git reset, etc. I find it useful to frequently look at the commit graph with gitk --all or a similar tool, just to check that I understand where all the different refs are pointing.

Alternatively, you could have just created a topic branch based on where your master is at in the first place (git branch new-work-including-merges) and then reset master as above. However, since your topic branch will include merges from origin/master and you've not pushed your changes yet, I'd suggest doing a rebase so that the history is tidier. (Also, when you eventually merge your topic branch back to master, the changes will be more obvious.)

There are 2 methods that I can think of to check whether a string has all digits of not

Method 1(Using the built-in isdigit() function in python):-

>>>st = '12345'
>>>st.isdigit()
True
>>>st = '1abcd'
>>>st.isdigit()
False

Method 2(Performing Exception Handling on top of the string):-

st="1abcd"
try:
    number=int(st)
    print("String has all digits in it")
except:
    print("String does not have all digits in it")

The output of the above code will be:

String does not have all digits in it

If you are running a standalone application then you have to use SparkContext instead of SparkSession

val conf = new SparkConf().setAppName("Samples").setMaster("local")
val sc = new SparkContext(conf)
val textData = sc.textFile("sample.txt").cache()

With Swift 1.2 (and maybe earlier) you now need to use:

let nums = [1, 6, 3, 9, 4, 6];
let numMax = nums.reduce(Int.min, combine: { max($0, $1) })

For working with Double values I used something like this:

let nums = [1.3, 6.2, 3.6, 9.7, 4.9, 6.3];
let numMax = nums.reduce(-Double.infinity, combine: { max($0, $1) })

Or:

String firstMacAddress = NetworkInterface
    .GetAllNetworkInterfaces()
    .Where( nic => nic.OperationalStatus == OperationalStatus.Up && nic.NetworkInterfaceType != NetworkInterfaceType.Loopback )
    .Select( nic => nic.GetPhysicalAddress().ToString() )

For Displaying digit upto two decimal places there are two possibilities - 1) Firstly, you only want to display decimal digits if it's there. For example - i) 12.10 to be displayed as 12.1, ii) 12.00 to be displayed as 12. Then use-

DecimalFormat formater = new DecimalFormat("#.##"); 

2) Secondly, you want to display decimal digits irrespective of decimal present For example -i) 12.10 to be displayed as 12.10. ii) 12 to be displayed as 12.00.Then use-

DecimalFormat formater = new DecimalFormat("0.00"); 

Modify your constructor to the following so that it calls the base class constructor properly:

public class MyExceptionClass : Exception
{
    public MyExceptionClass(string message, string extrainfo) : base(message)
    {
        //other stuff here
    }
}

Note that a constructor is not something that you can call anytime within a method. That's the reason you're getting errors in your call in the constructor body.

List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("param1","value1");

String query = URLEncodedUtils.format(params, "utf-8");

URI url = URIUtils.createURI(scheme, userInfo, authority, port, path, query, fragment); //can be null
HttpGet httpGet = new HttpGet(url);

Note: url = new URI(...) is buggy

Address already in use means that the port you are trying to allocate for your current execution is already occupied/allocated to some other process.

If you are a developer and if you are working on an application which require lots of testing, you might have an instance of your same application running in background (may be you forgot to stop it properly)

So if you encounter this error, just see which application/process is using the port.

In linux try using netstat -tulpn. This command will list down a process list with all running processes.

Check if an application is using your port. If that application or process is another important one then you might want to use another port which is not used by any process/application.

Anyway you can stop the process which uses your port and let your application take it.

If you are in linux environment try,

• Use netstat -tulpn to display the processes
• kill <pid> This will terminate the process

If you are using windows,

• Use netstat -a -o -n to check for the port usages
• Use taskkill /F /PID <pid> to kill that process

My fellows,

In January 2019 I used a code made before:

 <script type="text/javascript">   
    function imprimir() {
        var divToPrint=document.getElementById("ConsutaBPM");
        newWin= window.open("");
        newWin.document.write(divToPrint.outerHTML);
        newWin.print();
        newWin.close();
    }
</script>

To undestand: ConsutaBPM is a DIV which contains inside phrases and tables. I wanted to print ALL, titles, table, and others. The problem was when TRIED to print the TABLE...

The table mas be defined with BORDER and CELLPADDING:

<table border='1' cellpadding='1' id='Tablbpm1' >

It worked fine!!!

The answer is that java.sql.Timestamp is a mess and should be avoided. Use java.time.LocalDateTime instead.

So why is it a mess? From the java.sql.Timestamp JavaDoc, a java.sql.Timestamp is a "thin wrapper around java.util.Date that allows the JDBC API to identify this as an SQL TIMESTAMP value". From the java.util.Date JavaDoc, "the Date class is intended to reflect coordinated universal time (UTC)". From the ISO SQL spec a TIMESTAMP WITHOUT TIME ZONE "is a data type that is datetime without time zone". TIMESTAMP is a short name for TIMESTAMP WITHOUT TIME ZONE. So a java.sql.Timestamp "reflects" UTC while SQL TIMESTAMP is "without time zone".

Because java.sql.Timestamp reflects UTC its methods apply conversions. This causes no end of confusion. From the SQL perspective it makes no sense to convert a SQL TIMESTAMP value to some other time zone as a TIMESTAMP has no time zone to convert from. What does it mean to convert 42 to Fahrenheit? It means nothing because 42 does not have temperature units. It's just a bare number. Similarly you can't convert a TIMESTAMP of 2020-07-22T10:38:00 to Americas/Los Angeles because 2020-07-22T10:30:00 is not in any time zone. It's not in UTC or GMT or anything else. It's a bare date time.

java.time.LocalDateTime is also a bare date time. It does not have a time zone, exactly like SQL TIMESTAMP. None of its methods apply any kind of time zone conversion which makes its behavior much easier to predict and understand. So don't use java.sql.Timestamp. Use java.time.LocalDateTime.

LocalDateTime ldt = rs.getObject(col, LocalDateTime.class);
ps.setObject(param, ldt, JDBCType.TIMESTAMP);

I think the lightsail as the name suggest is light weight and meant for initial development. For production sites and apps with high volume it simply becomes unavailable and hangs....It is just a sandbox to play with things. Further lack of support reduces its reliability. There should be an option to migrate to EC2, when u fully develop your apps or sites..So that with same minimum configuration you can migrate to scalable EC2..

The obj directory is for intermediate object files and other transient data files that are generated by the compiler or build system during a build. The bin directory is the directory that final output binaries (and any dependencies or other deployable files) will be written to.

You can change the actual directories used for both purposes within the project settings, if you like.

I'm assuming this should work. This will actually put it in the column in your database

UPDATE yourTable yt SET yt.Total = (yt.Pieces * yt.Price)

If you want to retrieve the 2 values from the database and put your multiplication in the third column of the result only, then

SELECT yt.Pieces, yt.Price, (yt.Pieces * yt.Price) as 'Total' FROM yourTable yt

will be your friend

Microsoft do not support C99 and haven't announced any plans to. I believe they intend to track C++ standards but consider C as effectively obsolete except as a subset of C++.

New projects in Visual Studio 2003 and later have the "Compile as C++ Code (/TP)" option set by default, so any .c files will be compiled as C++.

For those who don't know, git ignores uppercase/lowercase name differences in files and folders. This turns out to be a nightmare when you rename them to the exact same name with a different case.

I encountered this issue when I renamed a folder from "Petstore" to "petstore" (uppercase to lowercase). I had edited my .git/config file to stop ignoring case, made changes, squashed my commits, and stashed my changes to move to a different branch. I could not apply my stashed changes to this other branch.

The fix that I found that worked was to temporarily edit my .git/config file to temporarily ignore case again. This caused git stash apply to succeed. Then, I changed ignoreCase back to false. I then added everything except for the new files in the petstore folder which git oddly claimed were deleted, for whatever reason. I committed my changes, then ran git reset --hard HEAD to get rid of those untracked new files. My commit appeared exactly as expected: the files in the folder were renamed.

I hope that this helps you avoid my same nightmare.

^((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)(\\.)){3}+((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?))$

Above will be regex for the ip address like: 221.234.000.112 also for 221.234.0.112, 221.24.03.112, 221.234.0.1

You can imagine all kind of address as above

The copy command is a SQL*Plus command (not a SQL Developer command). If you have your tnsname entries setup for SID1 and SID2 (e.g. try a tnsping), you should be able to execute your command.

Another assumption is that table1 has the same columns as the message_table (and the columns have only the following data types: CHAR, DATE, LONG, NUMBER or VARCHAR2). Also, with an insert command, you would need to be concerned about primary keys (e.g. that you are not inserting duplicate records).

I tried a variation of your command as follows in SQL*Plus (with no errors):

copy from scott/tiger@db1 to scott/tiger@db2 create new_emp using select * from emp;

After I executed the above statement, I also truncate the new_emp table and executed this command:

copy from scott/tiger@db1 to scott/tiger@db2 insert new_emp using select * from emp;

With SQL Developer, you could do the following to perform a similar approach to copying objects:

1. On the tool bar, select Tools>Database copy.

2. Identify source and destination connections with the copy options you would like.

3. For object type, select table(s).

4. Specify the specific table(s) (e.g. table1).

The copy command approach is old and its features are not being updated with the release of new data types. There are a number of more current approaches to this like Oracle's data pump (even for tables).

The first time I realized that the Unit testing project referenced the app.config in that project rather then the app.config associated with my production code project (off course, DOH) I just added a line in the Post Build Event of the Prod project that will copy the app.config to the bin folder of the test project.

RANK() OVER (ORDER BY totals DESC) AS xRank

Have a look at this example:

SQL Fiddle DEMO

You might also want to have a look at the difference between RANK (Transact-SQL) and DENSE_RANK (Transact-SQL):

RANK (Transact-SQL)

If two or more rows tie for a rank, each tied rows receives the same rank. For example, if the two top salespeople have the same SalesYTD value, they are both ranked one. The salesperson with the next highest SalesYTD is ranked number three, because there are two rows that are ranked higher. Therefore, the RANK function does not always return consecutive integers.

DENSE_RANK (Transact-SQL)

Returns the rank of rows within the partition of a result set, without any gaps in the ranking. The rank of a row is one plus the number of distinct ranks that come before the row in question.

"Topology was destroyed" might be caused by mongoose disconnecting before mongo document indexes are created, per this comment

In order to make sure all models have their indexes built before disconnecting, you can:

await Promise.all(mongoose.modelNames().map(model => mongoose.model(model).ensureIndexes()));

await mongoose.disconnect();

@"string here
that is long you mean"

But be careful, because

@"string here
           and space before this text
     means the space is also a part of the string"

It also escapes things in the string

@"c:\\folder" // c:\\folder
@"c:\folder" // c:\folder
"c:\\folder" // c:\folder

Regexes can also limit the number of characters.

r = re.compile("^[a-z]{1,15}$")

gives you a regex that only matches if the input is entirely lowercase ASCII letters and 1 to 15 characters long.

If you have to do group by using hibernate criteria use projections.groupPropery like the following,

@Autowired
private SessionFactory sessionFactory;
Criteria crit = sessionFactory.getCurrentSession().createCriteria(studentModel.class);
crit.setProjection(Projections.projectionList()
            .add(Projections.groupProperty("studentName").as("name"))
List result = crit.setResultTransformer(Criteria.ALIAS_TO_ENTITY_MAP).list(); 
return result;  

Based on quick inspection of google web, this would be CSS path to links in page list

ol[id="rso"] h3[class="r"] a

So you should do something like

String path = "ol[id='rso'] h3[class='r'] a";
driver.findElements(By.cssSelector(path)).get(2).click();

However you could also use xpath which is not really recommended as a best practice and also JQuery locators but I am not sure if you can use them aynywhere else except inArquillian Graphene

This happens because your local module named urllib.py shadows the installed requests module you are trying to use. The current directory is preapended to sys.path, so the local name takes precedence over the installed name.

An extra debugging tip when this comes up is to look at the Traceback carefully, and realize that the name of your script in question is matching the module you are trying to import.

Rename your file to something else like url.py. Then It is working fine. Hope it helps!

A possible solution might be to use the JSON dumps() method, so you can convert the dictionary to a string ---

import json

a={"a":10, "b":20}
b={"b":20, "a":10}
c = [json.dumps(a), json.dumps(b)]


set(c)
json.dumps(a) in c

Output -

set(['{"a": 10, "b": 20}'])
True

This works great for large tables.

SELECT NUM_ROWS FROM ALL_TABLES WHERE TABLE_NAME = 'TABLE_NAME_IN_UPPERCASE';

For small to medium size tables, following will be ok.

SELECT COUNT(Primary_Key) FROM table_name;

In urls.py you can override the 3 most important variables:

from django.contrib import admin

admin.site.site_header = 'My project'                    # default: "Django Administration"
admin.site.index_title = 'Features area'                 # default: "Site administration"
admin.site.site_title = 'HTML title from adminsitration' # default: "Django site admin"

The main difference is GIF is patented and a bit more widely supported. PNG is an open specification and alpha transparency is not supported in IE6. Support was improved in IE7, but not completely fixed.

As far as file sizes go, GIF has a smaller default color pallet, so they tend to be smaller file sizes at first glance. PNG files have a larger default pallet, however you can shrink their color pallet so that, when you do, they result in a smaller file size than GIF. The issue again is that this feature isn't as supported in Internet Explorer.

Also, because PNGs can support alpha transparency, they're the only option if you want a variation of transparency other than binary transparency.

What are iml files in Android Studio project?

A Google search on iml file turns up:

IML is a module file created by IntelliJ IDEA, an IDE used to develop Java applications. It stores information about a development module, which may be a Java, Plugin, Android, or Maven component; saves the module paths, dependencies, and other settings.

(from this page)

why not to use gradle scripts to integrate with external modules that you add to your project.

You do "use gradle scripts to integrate with external modules", or your own modules.

However, Gradle is not IntelliJ IDEA's native project model — that is separate, held in .iml files and the metadata in .idea/ directories. In Android Studio, that stuff is largely generated out of the Gradle build scripts, which is why you are sometimes prompted to "sync project with Gradle files" when you change files like build.gradle. This is also why you don't bother putting .iml files or .idea/ in version control, as their contents will be regenerated.

If I have a team that work in different IDE's like Eclipse and AS how to make project IDE agnostic?

To a large extent, you can't.

You are welcome to have an Android project that uses the Eclipse-style directory structure (e.g., resources and manifest in the project root directory). You can teach Gradle, via build.gradle, how to find files in that structure. However, other metadata (compileSdkVersion, dependencies, etc.) will not be nearly as easily replicated.

Other alternatives include:

• Move everybody over to another build system, like Maven, that is equally integrated (or not, depending upon your perspective) to both Eclipse and Android Studio

• Hope that Andmore takes off soon, so that perhaps you can have an Eclipse IDE that can build Android projects from Gradle build scripts

• Have everyone use one IDE

PHP_EOL is a predefined constant in PHP since PHP 4.3.10 and PHP 5.0.2. See the manual posting:

Using this will save you extra coding on cross platform developments.

IE.

$data = 'some data'.PHP_EOL;
$fp = fopen('somefile', 'a');
fwrite($fp, $data);

If you looped through this twice you would see in 'somefile':

some data
some data

Bind the button, this is done with jQuery:

$("#my-table input[type='button']").click(function(){
    var parameter = $(this).val();
    window.location = "http://yoursite.com/page?variable=" + parameter;
});

You can do something like this:

function writeFile(i){
    var i = i || 0;
    var fileName = 'a_' + i + '.jpg';
    fs.exists(fileName, function (exists) {
        if(exists){
            writeFile(++i);
        } else {
            fs.writeFile(fileName);
        }
    });
}

You should have sdiff for side-by-side merge of file differences. Take a read of man sdiff for the full story.

I had a same issue and while googling I found your question. Yes marked answer worked for me also but there was some issue.
Anyways I found another solution. which works perfectly without doing any jugglery.

Small performance test comparision for three solutions:

1. $(".link").prop('href',"https://example.com")
2. $(".link").attr('href',"https://example.com")
3. document.querySelector(".link").href="https://example.com";

Here you can perform test by yourself https://jsperf.com/a-href-js-change

We can read href values in following ways

1. let href = $(selector).prop('href');
2. let href = $(selector).attr('href');
3. let href = document.querySelector(".link").href;

Here you can perform test by yourself https://jsperf.com/a-href-js-read

If you want to compare with a particular date , You can directly write it like :

select * from `table_name` where timestamp >= '2018-07-07';

// here the timestamp is the name of the column having type as timestamp

or

For fetching today date , CURDATE() function is available , so :

select * from `table_name` where timestamp >=  CURDATE();

Try:

UPDATE Dispatch_Post
SET isSync = 1
WHERE ChallanNo 
IN (SELECT TOP 1000 ChallanNo FROM dbo.Dispatch_Post ORDER BY 
CreatedDate DESC)

Your css is almost correct. You are just missing display: block; in image css. Also one typo in your id. It should be <div id="ImageContainer">

div#ImageContainer { width: 600px; }

<div id="ImageContainer">_x000D_

It's top google stackoverflow question, but all answers are not jQuery related!

$(".someclass").click(
    function(event)
    {
        console.log(event, this);
    }
);

'event' contains 2 important values:

event.currentTarget - element to which event is triggered ('.someclass' element)

event.target - element clicked (in case when inside '.someclass' [div] are other elements and you clicked on of them)

this - is set to triggered element ('.someclass'), but it's JavaScript element, not jQuery element, so if you want to use some jQuery function on it, you must first change it to jQuery element: $(this)

When your refresh the page and reload the scripts again; this method not work. You have to use jquery "unbind" method.

Try this:

from tkinter import *
import os
import sys

root = Tk()
root.iconbitmap(os.path.join(sys.path[0], '<your-ico-file>'))

root.mainloop()

Note: replace <your-ico-file> with the name of the ico file you are using otherwise it won't work.

I have tried this in Python 3. It worked.

convert to Array

var array = like.ToArray();
var first = array[0];

You can define a method in spec_helper.rb that sends a message both to Rails.logger.info and to puts and use that for debugging:

def log_test(message)
    Rails.logger.info(message)
    puts message
end

You can also use ng-template (instead of template. See the note for the caveat of using template tag) for applying both *ngFor and ngIf on the same HTML element. Here is an example where you can use both *ngIf and *ngFor for the same tr element in the angular table.

<tr *ngFor = "let fruit of fruiArray">
    <ng-template [ngIf] = "fruit=='apple'>
        <td> I love apples!</td>
    </ng-template>
</tr>

where fruiArray = ['apple', 'banana', 'mango', 'pineapple'].

Note:

The caveat of using just the template tag instead of ng-template tag is that it throws StaticInjectionError in some places.

You can follow the format below and can use the testingObjectiveCBlock property in the class.

I like the jQuery function extension. However, the this refers to the jQuery object not the DOM object. So I've modified it a little to make it even better (can update in multiple textboxes / textareas at once).

jQuery.fn.extend({
insertAtCaret: function(myValue){
  return this.each(function(i) {
    if (document.selection) {
      //For browsers like Internet Explorer
      this.focus();
      var sel = document.selection.createRange();
      sel.text = myValue;
      this.focus();
    }
    else if (this.selectionStart || this.selectionStart == '0') {
      //For browsers like Firefox and Webkit based
      var startPos = this.selectionStart;
      var endPos = this.selectionEnd;
      var scrollTop = this.scrollTop;
      this.value = this.value.substring(0, startPos)+myValue+this.value.substring(endPos,this.value.length);
      this.focus();
      this.selectionStart = startPos + myValue.length;
      this.selectionEnd = startPos + myValue.length;
      this.scrollTop = scrollTop;
    } else {
      this.value += myValue;
      this.focus();
    }
  });
}
});

This works really well. You can insert into multiple places at once, like:

$('#element1, #element2, #element3, .class-of-elements').insertAtCaret('text');

bool is just a macro that expands to _Bool. You can use _Bool with no #include very much like you can use int or double; it is a C99 keyword.

The macro is defined in <stdbool.h> along with 3 other macros.

The macros defined are

• bool: macro expands to _Bool
• false: macro expands to 0
• true: macro expands to 1
• __bool_true_false_are_defined: macro expands to 1

I think a more straightforward solution and faster to boot is to do the following:

import numpy as np
N = 10
a = np.random.rand(N,N)
b = np.zeros((N,N+1))
b[:,:-1] = a

And timings:

In [23]: N = 10

In [24]: a = np.random.rand(N,N)

In [25]: %timeit b = np.hstack((a,np.zeros((a.shape[0],1))))
10000 loops, best of 3: 19.6 us per loop

In [27]: %timeit b = np.zeros((a.shape[0],a.shape[1]+1)); b[:,:-1] = a
100000 loops, best of 3: 5.62 us per loop

Try adding ?wsdl to the string.

file_get_contents will do what you want

$output = file_get_contents('http://www.example.com/');
echo $output;

Edit: One way to fire off a GET request and return immediately.

Quoted from http://petewarden.typepad.com/searchbrowser/2008/06/how-to-post-an.html

function curl_post_async($url, $params)
{
    foreach ($params as $key => &$val) {
      if (is_array($val)) $val = implode(',', $val);
        $post_params[] = $key.'='.urlencode($val);
    }
    $post_string = implode('&', $post_params);

    $parts=parse_url($url);

    $fp = fsockopen($parts['host'],
        isset($parts['port'])?$parts['port']:80,
        $errno, $errstr, 30);

    $out = "POST ".$parts['path']." HTTP/1.1\r\n";
    $out.= "Host: ".$parts['host']."\r\n";
    $out.= "Content-Type: application/x-www-form-urlencoded\r\n";
    $out.= "Content-Length: ".strlen($post_string)."\r\n";
    $out.= "Connection: Close\r\n\r\n";
    if (isset($post_string)) $out.= $post_string;

    fwrite($fp, $out);
    fclose($fp);
}

What this does is open a socket, fire off a get request, and immediately close the socket and return.

Units:

The amount of "neurons", or "cells", or whatever the layer has inside it.

It's a property of each layer, and yes, it's related to the output shape (as we will see later). In your picture, except for the input layer, which is conceptually different from other layers, you have:

• Hidden layer 1: 4 units (4 neurons)
• Hidden layer 2: 4 units
• Last layer: 1 unit

Shapes

Shapes are consequences of the model's configuration. Shapes are tuples representing how many elements an array or tensor has in each dimension.

Ex: a shape (30,4,10) means an array or tensor with 3 dimensions, containing 30 elements in the first dimension, 4 in the second and 10 in the third, totaling 30*4*10 = 1200 elements or numbers.

The input shape

What flows between layers are tensors. Tensors can be seen as matrices, with shapes.

In Keras, the input layer itself is not a layer, but a tensor. It's the starting tensor you send to the first hidden layer. This tensor must have the same shape as your training data.

Example: if you have 30 images of 50x50 pixels in RGB (3 channels), the shape of your input data is (30,50,50,3). Then your input layer tensor, must have this shape (see details in the "shapes in keras" section).

Each type of layer requires the input with a certain number of dimensions:

• Dense layers require inputs as (batch_size, input_size)
  • or (batch_size, optional,...,optional, input_size)
• 2D convolutional layers need inputs as:
  • if using channels_last: (batch_size, imageside1, imageside2, channels)
  • if using channels_first: (batch_size, channels, imageside1, imageside2)
• 1D convolutions and recurrent layers use (batch_size, sequence_length, features)
  • Details on how to prepare data for recurrent layers

Now, the input shape is the only one you must define, because your model cannot know it. Only you know that, based on your training data.

All the other shapes are calculated automatically based on the units and particularities of each layer.

Relation between shapes and units - The output shape

Given the input shape, all other shapes are results of layers calculations.

The "units" of each layer will define the output shape (the shape of the tensor that is produced by the layer and that will be the input of the next layer).

Each type of layer works in a particular way. Dense layers have output shape based on "units", convolutional layers have output shape based on "filters". But it's always based on some layer property. (See the documentation for what each layer outputs)

Let's show what happens with "Dense" layers, which is the type shown in your graph.

A dense layer has an output shape of (batch_size,units). So, yes, units, the property of the layer, also defines the output shape.

• Hidden layer 1: 4 units, output shape: (batch_size,4).
• Hidden layer 2: 4 units, output shape: (batch_size,4).
• Last layer: 1 unit, output shape: (batch_size,1).

Weights

Weights will be entirely automatically calculated based on the input and the output shapes. Again, each type of layer works in a certain way. But the weights will be a matrix capable of transforming the input shape into the output shape by some mathematical operation.

In a dense layer, weights multiply all inputs. It's a matrix with one column per input and one row per unit, but this is often not important for basic works.

In the image, if each arrow had a multiplication number on it, all numbers together would form the weight matrix.

Shapes in Keras

Earlier, I gave an example of 30 images, 50x50 pixels and 3 channels, having an input shape of (30,50,50,3).

Since the input shape is the only one you need to define, Keras will demand it in the first layer.

But in this definition, Keras ignores the first dimension, which is the batch size. Your model should be able to deal with any batch size, so you define only the other dimensions:

input_shape = (50,50,3)
    #regardless of how many images I have, each image has this shape        

Optionally, or when it's required by certain kinds of models, you can pass the shape containing the batch size via batch_input_shape=(30,50,50,3) or batch_shape=(30,50,50,3). This limits your training possibilities to this unique batch size, so it should be used only when really required.

Either way you choose, tensors in the model will have the batch dimension.

So, even if you used input_shape=(50,50,3), when keras sends you messages, or when you print the model summary, it will show (None,50,50,3).

The first dimension is the batch size, it's None because it can vary depending on how many examples you give for training. (If you defined the batch size explicitly, then the number you defined will appear instead of None)

Also, in advanced works, when you actually operate directly on the tensors (inside Lambda layers or in the loss function, for instance), the batch size dimension will be there.

• So, when defining the input shape, you ignore the batch size: input_shape=(50,50,3)
• When doing operations directly on tensors, the shape will be again (30,50,50,3)
• When keras sends you a message, the shape will be (None,50,50,3) or (30,50,50,3), depending on what type of message it sends you.

Dim

And in the end, what is dim?

If your input shape has only one dimension, you don't need to give it as a tuple, you give input_dim as a scalar number.

So, in your model, where your input layer has 3 elements, you can use any of these two:

• input_shape=(3,) -- The comma is necessary when you have only one dimension
• input_dim = 3

But when dealing directly with the tensors, often dim will refer to how many dimensions a tensor has. For instance a tensor with shape (25,10909) has 2 dimensions.

Defining your image in Keras

Keras has two ways of doing it, Sequential models, or the functional API Model. I don't like using the sequential model, later you will have to forget it anyway because you will want models with branches.

PS: here I ignored other aspects, such as activation functions.

With the Sequential model:

from keras.models import Sequential  
from keras.layers import *  

model = Sequential()    

#start from the first hidden layer, since the input is not actually a layer   
#but inform the shape of the input, with 3 elements.    
model.add(Dense(units=4,input_shape=(3,))) #hidden layer 1 with input

#further layers:    
model.add(Dense(units=4)) #hidden layer 2
model.add(Dense(units=1)) #output layer   

With the functional API Model:

from keras.models import Model   
from keras.layers import * 

#Start defining the input tensor:
inpTensor = Input((3,))   

#create the layers and pass them the input tensor to get the output tensor:    
hidden1Out = Dense(units=4)(inpTensor)    
hidden2Out = Dense(units=4)(hidden1Out)    
finalOut = Dense(units=1)(hidden2Out)   

#define the model's start and end points    
model = Model(inpTensor,finalOut)

Shapes of the tensors

Remember you ignore batch sizes when defining layers:

• inpTensor: (None,3)
• hidden1Out: (None,4)
• hidden2Out: (None,4)
• finalOut: (None,1)

session_start();          //php part
$_SESSION['student']=array();
$student_name=$_POST['student_name']; //student_name form field name
$student_city=$_POST['city_id'];   //city_id form field name
array_push($_SESSION['student'],$student_name,$student_city);   
//print_r($_SESSION['student']);


<table class="table">     //html part
    <tr>
      <th>Name</th>
      <th>City</th>
    </tr>

    <tr>
     <?php for($i = 0 ; $i < count($_SESSION['student']) ; $i++) {
     echo '<td>'.$_SESSION['student'][$i].'</td>';
     }  ?>
    </tr>
</table>

you can return the entire row instead of values:

df = df.apply(extract_text_features,axis = 1)

where the function returns the row

def extract_text_features(row):
      row['new_col1'] = value1
      row['new_col2'] = value2
      return row

So you can change it programmatically easily by using homeAsUpIndicator() function that added in android API level 18 and upper.

ActionBar().setHomeAsUpIndicator(R.drawable.ic_yourindicator);

If you use support library

getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_yourindicator);

Here is how I do it on iOS 9 in Swift -

import UIKit

class CustomView : UIView {

    init() {
        super.init(frame: UIScreen.mainScreen().bounds);

        //for debug validation
        self.backgroundColor = UIColor.blueColor();
        print("My Custom Init");

        return;
    }

    required init?(coder aDecoder: NSCoder) { fatalError("init(coder:) has not been implemented"); }
}

Here is a full project with example:

• UIView Example Project (with SubView example)

Remove lib from Podfile, then pod install again.

You should be able to utilize the asterisk and !important elements within CSS.

html *
{
   font-size: 1em !important;
   color: #000 !important;
   font-family: Arial !important;
}

The asterisk matches everything (you could probably get away without the html too).

The !important ensures that nothing can override what you've set in this style (unless it is also important). (this is to help with your requirement that it should "ignore inner formatting of text" - which I took to mean that other styles could not overwrite these)

The rest of the style within the braces is just like any other styling and you can do whatever you'd like to in there. I chose to change the font size, color and family as an example.

There are many ways to exit a JS or Node script. Here are the most relevant:

// This will never exit!
setInterval((function() {  
    return;
}), 5000);

// This will exit after 5 seconds, with signal 1
setTimeout((function() {  
    return process.exit(1);
}), 5000);

// This will also exit after 5 seconds, and print its (killed) PID
setTimeout((function() {  
    return process.kill(process.pid);
}), 5000);

// This will also exit after 5 seconds and create a core dump.
setTimeout((function() {  
    return process.abort();
}), 5000);

If you're in the REPL (i.e. after running node on the command line), you can type .exit to exit.

You only have to get the view of activity that carry this fragment and this could only happen when your fragment is already created

override the onViewCreated() method inside your fragment and enjoy its magic :) ..

@Override

    super.onViewCreated(view, savedInstanceState);
    Button button = (Button) view.findViewById(R.id.YOURBUTTONID);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

Authentication is a property of a thread in server environment in the same way as it is a property of a process in OS. Having a bean instance for accessing authentication information would be inconvenient configuration and wiring overhead without any benefit.

Regarding test authentication there are several ways how you can make your life easier. My favourite is to make a custom annotation @Authenticated and test execution listener, which manages it. Check DirtiesContextTestExecutionListener for inspiration.

You need to use an undocumented trick with Excel's LINEST function:

=LINEST(known_y's, [known_x's], [const], [stats])

Background

A regular linear regression is calculated (with your data) as:

=LINEST(B2:B21,A2:A21)

which returns a single value, the linear slope (m) according to the formula:

which for your data:

is:

Undocumented trick Number 1

You can also use Excel to calculate a regression with a formula that uses an exponent for x different from 1, e.g. x^1.2:

using the formula:

=LINEST(B2:B21, A2:A21^1.2)

which for you data:

is:

You're not limited to one exponent

Excel's LINEST function can also calculate multiple regressions, with different exponents on x at the same time, e.g.:

=LINEST(B2:B21,A2:A21^{1,2})

Note: if locale is set to European (decimal symbol ","), then comma should be replaced by semicolon and backslash, i.e. =LINEST(B2:B21;A2:A21^{1\2})

Now Excel will calculate regressions using both x¹ and x² at the same time:

How to actually do it

The impossibly tricky part there's no obvious way to see the other regression values. In order to do that you need to:

• select the cell that contains your formula:

  

• extend the selection the left 2 spaces (you need the select to be at least 3 cells wide):

  

• press F2

• press Ctrl+Shift+Enter

  

You will now see your 3 regression constants:

  y = -0.01777539x^2 + 6.864151123x + -591.3531443

Bonus Chatter

I had a function that I wanted to perform a regression using some exponent:

y = m×x^k + b

But I didn't know the exponent. So I changed the LINEST function to use a cell reference instead:

=LINEST(B2:B21,A2:A21^F3, true, true)

With Excel then outputting full stats (the 4th paramter to LINEST):

I tell the Solver to maximize R²:

And it can figure out the best exponent. Which for you data:

is:

A very short way to do it is just right click on the activity_main.xml design background and select convert view then select Relativealayout. Your code in Xml Text will auto. Change. Goodluck

So for example, if type = 30 then OpenCV data type is CV_64FC4. If type = 50 then the OpenCV data type is CV_16UC(7).

It is possible to play a local video file.

<input type="file" accept="video/*"/>
<video controls autoplay></video>

When a file is selected via the input element:

1. 'change' event is fired
2. Get the first File object from the input.files FileList
3. Make an object URL that points to the File object
4. Set the object URL to the video.src property

5. Lean back and watch :)

You have a few options.

1. Use Android assets studios Android Holo colors generator to generate the resources, styles and themes you need to add to your app to get the holo look across all devices.

2. Use holo everywhere library.

3. Use the PNG for the holo text fields and set them as background images yourself. You can get the images from the Android assets studios holo color generator. You'll have to make a drawable and define the normal, selected and disabled states.

UPDATE 2016-01-07

This answer is now outdated. Android has tinting API and ability to theme on controls directly now. A good reference for how to style or theme any element is a site called materialdoc.

I'm guessing that your complaint is that the exception is not firing. PDO is most likely configured to not throw exceptions. Enable them with this:

$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); 

This usually happens to me if I misplace a return statement, for example:

Adding a return statement, or in my case, moving it to correct scope will do the trick:

Here's how I do file upload in react using axios

import React from 'react'
import axios, { post } from 'axios';

class SimpleReactFileUpload extends React.Component {

  constructor(props) {
    super(props);
    this.state ={
      file:null
    }
    this.onFormSubmit = this.onFormSubmit.bind(this)
    this.onChange = this.onChange.bind(this)
    this.fileUpload = this.fileUpload.bind(this)
  }

  onFormSubmit(e){
    e.preventDefault() // Stop form submit
    this.fileUpload(this.state.file).then((response)=>{
      console.log(response.data);
    })
  }

  onChange(e) {
    this.setState({file:e.target.files[0]})
  }

  fileUpload(file){
    const url = 'http://example.com/file-upload';
    const formData = new FormData();
    formData.append('file',file)
    const config = {
        headers: {
            'content-type': 'multipart/form-data'
        }
    }
    return  post(url, formData,config)
  }

  render() {
    return (
      <form onSubmit={this.onFormSubmit}>
        <h1>File Upload</h1>
        <input type="file" onChange={this.onChange} />
        <button type="submit">Upload</button>
      </form>
   )
  }
}

More simply you can utilize DropBox for this. The steps basically remain the same. You can do the following-:

1) upload your .ipa to dropBox, Share the link for this .ipa

2) Paste the shared link for .ipa in your manifest.plist file , Upload manifest file in DropBox again share the link for this .plist file

3)paste the link for this Plist in your index.html file with a suitable tag.

Share this index.html file with anybody who can tap on the URL and download. or you can directly hit the URL instead.

Try to create a file using the code, so you will get to know the path of the file where the system create

File test=new File("check.txt");
if (test.createNewFile()) {
    System.out.println("File created: " + test.getName());
  }

docker inspect <containername> | grep log

Just use:

git reset HEAD <filename>

This unstages the file and keeps the changes you did to it, so you can, in turn, change branches if you wanted and git add those files to another branch instead. All changes are kept.

Currently, looking at the Swift Standard Library Reference for Dictionary, there is no way to easy update a dictionary with another one.

You can write an extension to do it

var dict1 = ["a" : "foo"]
var dict2 = ["b" : "bar"]

extension Dictionary {
    mutating func update(other:Dictionary) {
        for (key,value) in other {
            self.updateValue(value, forKey:key)
        }
    }
}

dict1.update(dict2)
// dict1 is now ["a" : "foo", "b" : "bar]

In Program.cs, between:

static int Main(string[] agrs)
{

and the rest of your code, add:

#if DEBUG
    int rtn = Main2(args);
    Console.WriteLine("return " + rtn);
    Console.WriteLine("ENTER to continue.");
    Console.Read();
    return rtn;
}

static int Main2(string[] args)
{
#endif

You cannot place checkbox inside select element but you can get the same functionality by using HTML, CSS and JavaScript. Here is a possible working solution. The explanation follows.

</form>

Explanation:

At first we create a select element that shows text "Select an option", and empty element that covers (overlaps) the select element (<div class="overSelect">). We do not want the user to click on the select element - it would show an empty options. To overlap the element with other element we use CSS position property with value relative | absolute.

To add the functionality we specify a JavaScript function that is called when the user clicks on the div that contains our select element (<div class="selectBox" onclick="showCheckboxes()">).

We also create div that contains our checkboxes and style it using CSS. The above mentioned JavaScript function just changes <div id="checkboxes"> value of CSS display property from "none" to "block" and vice versa.

The solution was tested in the following browsers: Internet Explorer 10, Firefox 34, Chrome 39. The browser needs to have JavaScript enabled.

Update null elements with value in the same location in other. Combines a DataFrame with other DataFrame using func to element-wise combine columns. The row and column indexes of the resulting DataFrame will be the union of the two.

df1 = pd.DataFrame({'A': [None, 0], 'B': [None, 4]})
df2 = pd.DataFrame({'A': [1, 1], 'B': [3, 3]})
df1.combine_first(df2)

If after the installation curl-dev luarocks does not see the headers:

find /usr -name 'curl.h'

luarocks install lua-cURL CURL_INCDIR=/usr/include/x86_64-linux-gnu/

Use the string's .replace method with a regex of \D, which is a shorthand character class that matches all non-digits:

myString = myString.replace(/\D/g,'');

I would probably go with Joran's suggestion of replacing 0's with NAs and then using the built in functions you mentioned. If you can't/don't want to do that, one approach is to use any() to find rows that contain 0's and subset those out:

set.seed(42)
#Fake data
x <- data.frame(a = sample(0:2, 5, TRUE), b = sample(0:2, 5, TRUE))
> x
  a b
1 2 1
2 2 2
3 0 0
4 2 1
5 1 2
#Subset out any rows with a 0 in them
#Note the negation with ! around the apply function
x[!(apply(x, 1, function(y) any(y == 0))),]
  a b
1 2 1
2 2 2
4 2 1
5 1 2

To implement Joran's method, something like this should get you started:

x[x==0] <- NA

You have to properly understand what is a "stdafx.h", aka precompiled header. Other questions or Wikipedia will answer that. In many cases a precompiled header can be avoided, especially if your project is small and with few dependencies. In your case, as you probably started from a template project, it was used to include Windows.h only for the _TCHAR macro.

Then, precompiled header is usually a per-project file in Visual Studio world, so:

1. Ensure you have the file "stdafx.h" in your project. If you don't (e.g. you removed it) just create a new temporary project and copy the default one from there;
2. Change the #include <stdafx.h> to #include "stdafx.h". It is supposed to be a project local file, not to be resolved in include directories.

Secondly: it's inadvisable to include the precompiled header in your own headers, to not clutter namespace of other source that can use your code as a library, so completely remove its inclusion in vector.h.

in React v16.8+ function component, you can use useState() to create a function state that lets you update the parent state, then pass it on to child as a props attribute, then inside the child component you can trigger the parent state function, the following is a working snippet:

For those unable to configure the mysql environment (e.g. due to lack of SUPER access) to use human-friendly timezone names like "America/Denver" or "GMT" you can also use the function with numeric offsets like this:

CONVERT_TZ(date,'+00:00','-07:00')

Simply you have to follow the following steps:

1. Power off your machine.
2. Right click on virtual machine name > Settings > Storage
3. Click on Controller : SATA > Add Hard Disk.
4. Choose the new hard disk drive type size and hit create.
5. Discard the machine state.
6. Insert Ubuntu Live CD.
7. Boot from ubuntu live cd.
8. Open "gparted" (It's installed, not need to installation).
9. Check if the system see your new created hard disk.
10. Open Terminal.
11. Type the following code.
12. sudo dd if=/dev/sda of=/dev/sdb (The first is the old partition path, the second is the new partition path).
13. Wait until its finish copying data (This step may take some time according to your host specs).
14. After finish copying, return to gparted and select refresh devices.
15. Select the new partition /dev/sdb it must be typical to the old one after doing dd command.
16. It'll show the expanded space as unlocated data.
17. Delete Swap partition/Extended partition.
18. Right click on root partition /dev/sdb > Resize
19. Allocate the whole space without swap allocation.
20. Create new extended partition > Choose extended > Create
21. Create new linux-swap partition > choose linux-swap > Create
22. Now turn off your running machine.
23. Right click on machine > settings > Storage.
24. Eject ubuntu live cd.
25. Right click on the old hard disk > remove attachment.
26. Now you can start your vm from the newly created hard disk.
27. Check the storage by enter df -kh command.
28. It must show you the new size.

Congratulation, enjoy your free space.

Use the Date.prototype.setFullYear method to set the year to what you want it to be.

For example:

var aYearFromNow = new Date();
aYearFromNow.setFullYear(aYearFromNow.getFullYear() + 1);

There really isn't another way to work with dates in JavaScript if these methods aren't present in the environment you are working with.

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

class MultiArg {

    Scanner sc;
    int n;
    String as;
    List<Integer> numList = new ArrayList<Integer>();

    public void fun() {
        sc = new Scanner(System.in);
        System.out.println("enter value");
        while (sc.hasNextInt())
            as = sc.nextLine();
    }

    public void diplay() {
        System.out.println("x");
        Integer[] num = numList.toArray(new Integer[numList.size()]);
        System.out.println("show value " + as);
        for (Integer m : num) {
            System.out.println("\t" + m);
        }
    }
}

but to terminate the while loop you have to put any charecter at the end of input.

ex. input:

12 34 56 78 45 67 .

output:

12 34 56 78 45 67

This is how I do my store procedures for MSSQL with an autogenerated ID.

CREATE PROCEDURE [dbo].[InsertProducts]
    @id             INT             = NULL OUT,
    @name           VARCHAR(150)    = NULL,
    @desc           VARCHAR(250)    = NULL

AS

    INSERT INTO dbo.Products
       (Name,
        Description)
    VALUES
       (@name,
        @desc)

    SET @id = SCOPE_IDENTITY();

Here:

df = df.reset_index()
df.columns[0] = 'New_ID'
df['New_ID'] = df.index + 880

Here is a way to do it without involving Console:

var endlessTask = new TaskCompletionSource<bool>().Task;
endlessTask.Wait();

The short answer is that history.pushState (not History.pushState, which would throw an exception, the window part is optional) will never do what you suggest.

If pages are refreshing, then it is caused by other things that you are doing (for example, you might have code running that goes to a new location in the case of the address bar changing).

history.pushState({urlPath:'/page2.php'},"",'/page2.php') works exactly like it is supposed to in the latest versions of Chrome, IE and Firefox for me and my colleagues.

In fact you can put whatever you like into the function: history.pushState({}, '', 'So long and thanks for all the fish.not a real file').

If you post some more code (with special attention for code nearby the history.pushState and anywhere document.location is used), then we'll be more than happy to help you figure out where exactly this issue is coming from.

If you post more code, I'll update this answer (I have your question favourited) :).

I like the Except extension methods, but the original question doesn't have symmetric key access and I prefer Contains (or the Any variation) to join, so with all credit to azuneca's answer:

public static IEnumerable<T> Except<T, TKey>(this IEnumerable<TKey> items,
    IEnumerable<T> other, Func<T, TKey> getKey) {

    return from item in items
        where !other.Contains(getKey(item))
        select item;
}

Which can then be used like:

var filteredApps = unfilteredApps.Except(excludedAppIds, ua => ua.Id);

Also, this version allows for needing a mapping for the exception IEnumerable by using a Select:

var filteredApps = unfilteredApps.Except(excludedApps.Select(a => a.Id), ua => ua.Id);

try this:

.test {
    position:absolute;
    background:blue;
    width:200px;
    height:200px;
    top:40px;
    transition:left 1s linear;
    left: 0;
}
