Paste this on your command line:

export LC_CTYPE="en_US.UTF-8" 

To those who are stuck wondering why a window flashes and goes away without doing anything, the problem may related to the RELATIVE path in your Python script. e.g. you used ".\". Even the Python script and Excel Workbook is in the same directory, the Current Directory may still be different. If you don't want to modify your code to change it to an absolute path. Just change your current Excel directory before you run the python script by:

ChDir ActiveWorkbook.Path

I'm just giving a example here. If the flash do appear, one of the first issues to check is the Current Working Directory.

Another useful command for easy determination is as below:

Command:

getconf LONG_BIT

Answer:

• 32, if OS is 32 bit
• 64, if OS is 64 bit

Map.of literals

As of Java 9, there is yet another way to instantiate a Map. You can create an unmodifiable map from zero, one, or several pairs of objects in a single-line of code. This is quite convenient in many situations.

For an empty Map that cannot be modified, call Map.of(). Why would you want an empty set that cannot be changed? One common case is to avoid returning a NULL where you have no valid content.

For a single key-value pair, call Map.of( myKey , myValue ). For example, Map.of( "favorite_color" , "purple" ).

For multiple key-value pairs, use a series of key-value pairs. ``Map.of( "favorite_foreground_color" , "purple" , "favorite_background_color" , "cream" )`.

If those pairs are difficult to read, you may want to use Map.of and pass Map.Entry objects.

Note that we get back an object of the Map interface. We do not know the underlying concrete class used to make our object. Indeed, the Java team is free to used different concrete classes for different data, or to vary the class in future releases of Java.

The rules discussed in other Answers still apply here, with regard to type-safety. You declare your intended types, and your passed objects must comply. If you want values of various types, use Object.

Map< String , Color > preferences = Map.of( "favorite_color" , Color.BLUE ) ;

You should be able to pass whatever credentials you want to the -Credential parameter. So something like:

$cred = Get-Credential

[Enter the credentials]

Copy-Item -Path $from -Destination $to -Credential $cred

For a new line, it's just

$list = explode("\n", $text);

For a new line and carriage return (as in Windows files), it's as you posted. Is your skuList a text area?

If your array contains elements of the primitive data type such as int, char, or string etc then you can user one of those methods which returns a copy of the original array such as .slice() or .map() or spread operator(thanks to ES6).

new_array = old_array.slice()

or

new_array = old_array.map((elem) => elem)

or

const new_array = new Array(...old_array);

BUT if your array contains complex elements such as objects(or arrays) or more nested objects, then, you will have to make sure that you are making a copy of all the elements from the top level to the last level else reference of the inner objects will be used and that means changing values in object_elements in new_array will still affect the old_array. You can call this method of copying at each level as making a DEEP COPY of the old_array.

For deep copying, you can use the above-mentioned methods for primitive data types at each level depending upon the type of data or you can use this costly method(mentioned below) for making a deep copy without doing much work.

var new_array = JSON.parse(JSON.stringify(old_array));

There are a lot of other methods out there which you can use depending on your requirements. I have mentioned only some of those for giving a general idea of what happens when we try to copy an array into the other by value.

The directory where st.rb lives is most likely not on your load path.

Assuming that st.rb is located in a directory called lib relative to where you invoke irb, you can add that lib directory to the list of directories that ruby uses to load classes or modules with this:

$: << 'lib'

For example, in order to call the module called 'foobar' (foobar.rb) that lives in the lib directory, I would need to first add the lib directory to the list of load path. Here, I am just appending the lib directory to my load path:

irb(main):001:0> require 'foobar'
LoadError: no such file to load -- foobar
        from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require'
        from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require'
        from (irb):1
irb(main):002:0> $:
=> ["/usr/lib/ruby/gems/1.8/gems/spoon-0.0.1/lib", "/usr/lib/ruby/gems/1.8/gems/interactive_editor-0.0.10/lib", "/usr/lib/ruby/site_ruby/1.8", "/usr/lib/ruby/site_ruby/1.8/i386-cygwin", "/usr/lib/ruby/site_ruby", "/usr/lib/ruby/vendor_ruby/1.8", "/usr/lib/ruby/vendor_ruby/1.8/i386-cygwin", "/usr/lib/ruby/vendor_ruby", "/usr/lib/ruby/1.8", "/usr/lib/ruby/1.8/i386-cygwin", "."]
irb(main):004:0> $: << 'lib'
=> ["/usr/lib/ruby/gems/1.8/gems/spoon-0.0.1/lib", "/usr/lib/ruby/gems/1.8/gems/interactive_editor-0.0.10/lib", "/usr/lib/ruby/site_ruby/1.8", "/usr/lib/ruby/site_ruby/1.8/i386-cygwin", "/usr/lib/ruby/site_ruby", "/usr/lib/ruby/vendor_ruby/1.8", "/usr/lib/ruby/vendor_ruby/1.8/i386-cygwin", "/usr/lib/ruby/vendor_ruby", "/usr/lib/ruby/1.8", "/usr/lib/ruby/1.8/i386-cygwin", ".", "lib"]
irb(main):005:0> require 'foobar'
=> true

EDIT Sorry, I completely missed the fact that you are using ruby 1.9.x. All accounts report that your current working directory has been removed from LOAD_PATH for security reasons, so you will have to do something like in irb:

$: << "."

In general error is which nobody can control or guess when it occurs.Exception can be guessed and can be handled. In Java Exception and Error are sub class of Throwable.It is differentiated based on the program control.Error such as OutOfMemory Error which no programmer can guess and can handle it.It depends on dynamically based on architectire,OS and server configuration.Where as Exception programmer can handle it and can avoid application's misbehavior.For example if your code is looking for a file which is not available then IOException is thrown.Such instances programmer can guess and can handle it.

Here is a class which I'm using in one of my projects. It redirects output of a subprocess to the log. At first I tried simply overwriting the write-method but that doesn't work as the subprocess will never call it (redirection happens on filedescriptor level). So I'm using my own pipe, similar to how it's done in the subprocess-module. This has the advantage of encapsulating all logging/printing logic in the adapter and you can simply pass instances of the logger to Popen: subprocess.Popen("/path/to/binary", stderr = LogAdapter("foo"))

class LogAdapter(threading.Thread):

    def __init__(self, logname, level = logging.INFO):
        super().__init__()
        self.log = logging.getLogger(logname)
        self.readpipe, self.writepipe = os.pipe()

        logFunctions = {
            logging.DEBUG: self.log.debug,
            logging.INFO: self.log.info,
            logging.WARN: self.log.warn,
            logging.ERROR: self.log.warn,
        }

        try:
            self.logFunction = logFunctions[level]
        except KeyError:
            self.logFunction = self.log.info

    def fileno(self):
        #when fileno is called this indicates the subprocess is about to fork => start thread
        self.start()
        return self.writepipe

    def finished(self):
       """If the write-filedescriptor is not closed this thread will
       prevent the whole program from exiting. You can use this method
       to clean up after the subprocess has terminated."""
       os.close(self.writepipe)

    def run(self):
        inputFile = os.fdopen(self.readpipe)

        while True:
            line = inputFile.readline()

            if len(line) == 0:
                #no new data was added
                break

            self.logFunction(line.strip())

If you don't need logging but simply want to use print() you can obviously remove large portions of the code and keep the class shorter. You could also expand it by an __enter__ and __exit__ method and call finished in __exit__ so that you could easily use it as context.

I found the answer.

Cast integer to string:

myOldIntValue|string

Cast string to integer:

myOldStrValue|int

I doubt there is one... It depends on browser, on printer (physical max dpi) and its driver, on paper size as you point out (and I might want to print on B5 paper too...), on settings (landscape or portrait?), plus you often can change the scale (percentage), etc.
Let the users tweak their settings...

After experiencing issues with sites breaking on Edge when using High Contrast Mode, I came across the following work by Jeff Clayton:

https://browserstrangeness.github.io/css_hacks.html

It's a crazy, weird media query, but those are easier to use in Sass:

@media screen and (min-width:0\0) and (min-resolution:+72dpi), \0screen\,screen\9 {
   .selector { rule: value };
}

This targets IE versions expect for IE8.

Or you can use:

@media screen\0 {
  .selector { rule: value };
}

Which targets IE8-11, but also triggers FireFox 1.x (which for my use case, doesn't matter).

Right now I'm testing with print support, and this seems to be working okay:

@media all\0 {
  .selector { rule: value };
}

You can use a library called underscore js. It gives a nice wrapper on the bind method and is a much cleaner syntax as well. Letting you execute the function in the specified scope.

http://underscorejs.org/#bind

_.bind(function, scope, *arguments)

The documentation for css() says that setting the style property to the empty string will remove that property if it does not reside in a stylesheet:

Setting the value of a style property to an empty string — e.g. $('#mydiv').css('color', '') — removes that property from an element if it has already been directly applied, whether in the HTML style attribute, through jQuery's .css() method, or through direct DOM manipulation of the style property. It does not, however, remove a style that has been applied with a CSS rule in a stylesheet or <style> element.

Since your styles are inline, you can write:

$(selector).css("-moz-user-select", "");

If you are creating a new rails application you can set the database using the -d switch like this:

rails -d mysql myapp

Its always easy to switch your database later though, and using sqlite really is easier if you are developing on a Mac.

Here is an example:

StartupWindow.java

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.SwingUtilities;


public class StartupWindow extends JFrame implements ActionListener
{
    private JButton btn;

    public StartupWindow()
    {
        super("Simple GUI");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        btn = new JButton("Open the other JFrame!");
        btn.addActionListener(this);
        btn.setActionCommand("Open");
        add(btn);
        pack();

    }

    @Override
    public void actionPerformed(ActionEvent e)
    {
        String cmd = e.getActionCommand();

        if(cmd.equals("Open"))
        {
            dispose();
            new AnotherJFrame();
        }
    }

    public static void main(String[] args)
    {
        SwingUtilities.invokeLater(new Runnable(){

            @Override
            public void run()
            {
                new StartupWindow().setVisible(true);
            }

        });
    }
}

AnotherJFrame.java

import javax.swing.JFrame;
import javax.swing.JLabel;

public class AnotherJFrame extends JFrame
{
    public AnotherJFrame()
    {
        super("Another GUI");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        add(new JLabel("Empty JFrame"));
        pack();
        setVisible(true);
    }
}

Also check that

<modules>
      <remove name="FormsAuthentication"/>
</modules>

If you found anything like this just remove:

<remove name="FormsAuthentication"/>

Line from web.config and here you go it will work fine I have tested it.

There is no direct way (i.e. using printf or another standard library function) to print it. You will have to write your own function.

/* This code has an obvious bug and another non-obvious one :) */
void printbits(unsigned char v) {
   for (; v; v >>= 1) putchar('0' + (v & 1));
}

If you're using terminal, you can use control codes to print out bytes in natural order:

void printbits(unsigned char v) {
    printf("%*s", (int)ceil(log2(v)) + 1, ""); 
    for (; v; v >>= 1) printf("\x1b[2D%c",'0' + (v & 1));
}

urlresolver has been removed in the higher version of Django - Please upgrade your django installation. I fixed it using the following command.

pip install django==2.0 --upgrade

itertools provides the chain function for that:

From http://docs.python.org/library/itertools.html#recipes:

def flatten(listOfLists):
    "Flatten one level of nesting"
    return chain.from_iterable(listOfLists)

Note that the result is an iterable, so you may need list(flatten(...)).

Declare SupportMapFragment object globally

    private SupportMapFragment mapFragment;

In onCreateView() method put below code

mapFragment = (SupportMapFragment) getChildFragmentManager()
            .findFragmentById(R.id.map);
 mapFragment.getMapAsync(this);

In onDestroyView() put below code

@Override
public void onDestroyView() {
   super.onDestroyView();

    if (mapFragment != null)
        getFragmentManager().beginTransaction().remove(mapFragment).commit();
}

In your xml file put below code

 <fragment
    android:id="@+id/map"
    android:name="com.abc.Driver.fragment.FragmentHome"
    class="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    />

Above code solved my problem and it's working fine

The error says that there is a mismatch, assuming that you have a common contract based on the same WSDL, then the mismatch is in the configuration.

For example that the client is using nettcpip and the server is set up to use basic http.

You can do this

x = {}
x['a'] = 1

There are some great answers mentioned here. Another approach you could take would be to use some free SDKs available online like Atooma, tranql and Neura, that can be integrated with your Android application (it takes less than 20 min to integrate). Along with giving you the accurate location of your user, it can also give you good insights about your user’s activities. Also, some of them consume less than 1% of your battery

function getSelectedText(elementId) {
    var elt = document.getElementById(elementId);

    if (elt.selectedIndex == -1)
        return null;

    return elt.options[elt.selectedIndex].text;
}

var text = getSelectedText('test');

By their nature, a small sample of random numbers doesn't have to be uniformly distributed. They're random, after all. I agree that if a random number generator is generating numbers that consistently appear to be grouped, then there is probably something wrong with it.

But keep in mind that randomness isn't necessarily uniform.

Edit: I added "small sample" to clarify.

You can use HTMLFormElement.prototype.reset according to MDN

document.getElementById("myForm").reset();

check this below code. this is for dropdown menu. In this if we select others then the text box will show otherwise text box will hide.

function show_txt(arg,arg1)
{
if(document.getElementById(arg).value=='other')
{
document.getElementById(arg1).style.display="block";
document.getElementById(arg).style.display="none";
}
else
{
document.getElementById(arg).style.display="block";
document.getElementById(arg1).style.display="none";
}
}
The HTML code here :

<select id="arg" onChange="show_txt('arg','arg1');">
<option>yes</option>
<option>No</option>
<option>Other</option>
</select>
<input type="text" id="arg1" style="display:none;">

In this situation implode($array,','); will works, becasue you want the values only. In PHP 5.6 working for me.

If you want to implode the keys and the values in one like :
blogTags_id: 1
tag_name: google

$toImplode=array();
foreach($array as $key => $value) {
$toImplode[]= "$key: $value".'<br>';
}
$imploded=implode('',$toImplode);

Sorry, I understand wrong, becasue the title "Implode data from a multi-dimensional array". Well, my answer still answer it somehow, may help someone, so will not delete it.

It seems that so far you've just followed the first step of the instructions, headed "Create an offline installation folder". Have you done the second step? "Install from the offline installation folder" - that is, install the certificates and then run vs_Community.exe from inside the folder.

this will do it with just javascript - you can also put the function in a .js file and call it with onclick

//button
<div onclick="
   document.forms['name_of_the_form']['name_of_the_input'].value += 'text you want to add to it'"
>button</div>

$result = mysql_query("SELECT option_value FROM wp_10_options WHERE option_name='homepage'");
$row = mysql_fetch_assoc($result);
echo $row['option_value'];

Its Ctrl + Shift + r

For me, there was only one option to discard all.

Datalist includes autocomplete and suggestions natively, it can also allow a user to enter a value that is not defined in the suggestions.

Select only gives you pre-defined options the user has to select from

You can try this website http://www.decompileandroid.com Just upload the .apk file and rest of it will be done by this site.

open the location in terminal then type these commands 1. chmod +x filename.sh 2. ./filename.sh that's it

I had an issue with connected repository. What's how I fixed:

I deleted manually .git folder under my project folder, run git init and then it all worked.

I think what you really want is an ArrayList or Vector. Arrays in Java are not like those in Javascript.

Don't worry...! Follow these below steps and you will get your signed .apk file. I was also worry about that, but these step get ride me off from the frustration. Steps to sign your application:

1. Export the unsigned package:

Right click on the project in Eclipse -> Android Tools -> Export Unsigned Application Package (like here we export our GoogleDriveApp.apk to Desktop)

Sign the application using your keystore and the jarsigner tool (follow below steps):

Open cmd-->change directory where your "jarsigner.exe" exist (like here in my system it exist at "C:\Program Files\Java\jdk1.6.0_17\bin"

Now enter belwo command in cmd:

jarsigner -verbose -keystore c:\users\android\debug.keystore c:\users\pir fahim\Desktops\GoogleDriveApp.apk my_keystore_alias

It will ask you to provide your password: Enter Passphrase for keystore: It will sign your apk.To verify that the signing is successful you can run:

jarsigner -verify c:\users\pir fahim\Desktops\GoogleDriveApp.apk

It should come back with: jar verified.

Method 2

If you are using eclipse with ADT, then it is simple to compiled, signed, aligned, and ready the file for distribution.what you have to do just follow this steps.

• File > Export.
• Export android application
• Browse-->select your project
• Next-->Next

These steps will compiled, signed and zip aligned your project and now you are ready to distribute your project or upload at Google Play store.

Send Json data string to a web address and get a result with method post

I had the same problem "PHP Fatal error: Cannot redeclare class XYZ.php".

I have two directories like controller and model and I uploaded by mistakenly XYZ.php in both directories.(so file with the same name cause the issue).

First solution:

Find in your whole project and make sure you have only one class XYZ.php.

Second solution:

Add a namespace in your class so you can use the same class name.

This is the date format:

The DATE type is used for values with a date part but no time part. MySQL retrieves and displays DATE values in 'YYYY-MM-DD' format. The supported range is '1000-01-01' to '9999-12-31'.

Why do you insert '07-25-2012' format when MySQL format is '2012-07-25'?. Actually you get this error if the sql_mode is traditional/strict mode else it just enters 0000-00-00 and gives a warning: 1265 - Data truncated for column 'col1' at row 1.

NetFilx is more of personalized media service but you can use it for public information regarding movies. It supports Javascript and OData.
Also look JMDb: The information is basically the same as you can get when using the IMDb website.

In my case, I needed to add the JMETER_HOME environment variable to be available via my Ant build scripts across all projects on my Jenkins server (Linux), in a way that would not interfere with my local build environment (Windows and Mac) in the build.xml script. Setting the environment variable via Manage Jenkins - Configure System - Global properties was the easiest and least intrusive way to accomplish this. No plug-ins are necessary.

The environment variable is then available in Ant via:

<property environment="env" />
<property name="jmeter.home" value="${env.JMETER_HOME}" />

This can be verified to works by adding:

<echo message="JMeter Home: ${jmeter.home}"/>

Which produces:

JMeter Home: ~/.jmeter

In addition to install the build tools and restart the update manager I also had to restart Eclipse to make this work.

I think @Erlend's use of HTMLDocument is the best way to go. However, I have also had good luck using this simple library:

SgmlReader

Why not simply set it up as a Scheduled Task that is scheduled to run at start up?

Simple source will help you. For Ex.

#!/bin/bash
echo "My shell_1"
source my_script1.sh
echo "Back in shell_1"

remove the range.

for i in myList

range takes in an integer. you want for each element in the list.

R has gotten to the point where the OS cannot allocate it another 75.1Mb chunk of RAM. That is the size of memory chunk required to do the next sub-operation. It is not a statement about the amount of contiguous RAM required to complete the entire process. By this point, all your available RAM is exhausted but you need more memory to continue and the OS is unable to make more RAM available to R.

Potential solutions to this are manifold. The obvious one is get hold of a 64-bit machine with more RAM. I forget the details but IIRC on 32-bit Windows, any single process can only use a limited amount of RAM (2GB?) and regardless Windows will retain a chunk of memory for itself, so the RAM available to R will be somewhat less than the 3.4Gb you have. On 64-bit Windows R will be able to use more RAM and the maximum amount of RAM you can fit/install will be increased.

If that is not possible, then consider an alternative approach; perhaps do your simulations in batches with the n per batch much smaller than N. That way you can draw a much smaller number of simulations, do whatever you wanted, collect results, then repeat this process until you have done sufficient simulations. You don't show what N is, but I suspect it is big, so try smaller N a number of times to give you N over-all.

There are a lot of answers here using mutt or mailx or people saying mail doesn't support "-a"

First, Ubuntu 14.0.4 mail from mailutils supports this:

mail -A filename -s "subject" [email protected]

Second, I found that by using the "man mail" command and searching for "attach"

Your error shows you are not compiling file with the definition of the insert function. Update your command to include the file which contains the definition of that function and it should work.

Try this it will work:

Intent logout_intent = new Intent(DashboardActivity.this, LoginActivity.class);
logout_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
logout_intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
logout_intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
startActivity(logout_intent);
finish();

Shortest way yet:

$ echo $[0x3F]
63

Here you can see the nature of Scanner:

double nextDouble()

Returns the next token as a double. If the next token is not a float or is out of range, InputMismatchException is thrown.

Try to catch the exception

try {
    // ...
} catch (InputMismatchException e) {
    System.out.print(e.getMessage()); //try to find out specific reason.
}

UPDATE

CASE 1

I tried your code and there is nothing wrong with it. Your are getting that error because you must have entered String value. When I entered a numeric value, it runs without any errors. But once I entered String it throw the same Exception which you have mentioned in your question.

CASE 2

You have entered something, which is out of range as I have mentioned above.

I'm really wondering what you could have tried to enter. In my system, it is running perfectly without changing a single line of code. Just copy as it is and try to compile and run it.

import java.util.*;

public class Test {
    public static void main(String... args) {
        new Test().askForMarks(5);
    }

    public void askForMarks(int student) {
        double marks[] = new double[student];
        int index = 0;
        Scanner reader = new Scanner(System.in);
        while (index < student) {
            System.out.print("Please enter a mark (0..30): ");
            marks[index] = (double) checkValueWithin(0, 30); 
            index++;
        }
    }

    public double checkValueWithin(int min, int max) {
        double num;
        Scanner reader = new Scanner(System.in);
        num = reader.nextDouble();                         
        while (num < min || num > max) {                 
            System.out.print("Invalid. Re-enter number: "); 
            num = reader.nextDouble();                         
        } 

        return num;
    }
}

As you said, you have tried to enter 1.0, 2.8 and etc. Please try with this code.

Note : Please enter number one by one, on separate lines. I mean, enter 2.7, press enter and then enter second number (e.g. 6.7).

One way, as suggested in this post, is to mention version in pip as:

pip install -Iv MySQL_python==1.2.2

i.e. Use == and mention the version number to install only that version. -I, --ignore-installed ignores already installed packages.

I have several library projects with the same package name specified in the AndroidManifest (so no duplicate field names are generated by R.java). I had to remove any permissions and activities from the AndroidManifest.xml for all library projects to remove the error so Manifest.java wasn't created multiple times. Hopefully this can help someone.

You can use the spread operator to convert Map.keys() iterator in an Array.

let myMap = new Map().set('a', 1).set('b', 2).set(983, true)_x000D_
let keys = [...myMap.keys()]_x000D_
console.log(keys)

If you want to use a color from colors.xml , experiment :

   public View getView(int position, View convertView, ViewGroup parent) {
        ... 
        View rowView = inflater.inflate(this.rowLayoutID, parent, false);
        rowView.setBackgroundColor(rowView.getResources().getColor(R.color.my_bg_color));
        TextView title = (TextView) rowView.findViewById(R.id.txtRowTitle);
        title.setTextColor(
            rowView.getResources().getColor(R.color.my_title_color));
        ...
     }

You can use too:

private static final int bgColor = 0xAAAAFFFF;
public View getView(int position, View convertView, ViewGroup parent) {
        ... 
        View rowView = inflater.inflate(this.rowLayoutID, parent, false);
            rowView.setBackgroundColor(bgColor);
...
}

To add my 2 cents, the exception can occur even if you call your code through System.Windows.Threading.Dispatcher.CurrentDispatcher.Invoke().
The point is that you have to call Invoke() of the Dispatcher of the control that you're trying to access, which in some cases may not be the same as System.Windows.Threading.Dispatcher.CurrentDispatcher. So instead you should use YourControl.Dispatcher.Invoke() to be safe. I was banging my head for a couple of hours before I realized this.

Update

For future readers, it looks like this has changed in the newer versions of .NET (4.0 and above). Now you no longer have to worry about the correct dispatcher when updating UI-backing properties in your VM. WPF engine will marshal cross-thread calls on the correct UI thread. See more details here. Thanks to @aaronburro for the info and link. You may also want to read our conversation below in comments.

IP can be any LAN or WAN IP address. But you'll want to set your firewall connection allow it.

Device connection with webserver pc can be by LAN or WAN (i.e by wifi, connectify, adhoc, cable, mypublic wifi etc)

You should follow these steps:

1. Go to the control panel
2. Inbound rules > new rules
3. Click port > next > specific local port > enter 8080 > next > allow the connection>
4. Next > tick all (domain, private, public) > specify any name
5. Now you can access your localhost by any device (laptop, mobile, desktop, etc).
6. Enter ip address in browser url as 123.23.xx.xx:8080 to access localhost by any device.

This IP will be of that device which has the web server.

Check if it's visible.

$("#singlechatpanel-1").is(':visible');

Check if it's hidden.

$("#singlechatpanel-1").is(':hidden');

json.loads() takes a JSON encoded string, not a filename. You want to use json.load() (no s) instead and pass in an open file object:

with open('/Users/JoshuaHawley/clean1.txt') as jsonfile:
    data = json.load(jsonfile)

The open() command produces a file object that json.load() can then read from, to produce the decoded Python object for you. The with statement ensures that the file is closed again when done.

The alternative is to read the data yourself and then pass it into json.loads().

Fiddle link : http://jsfiddle.net/7LXPq/93/

Two problems in this:

1. Date control in HTML 5 accepts in the format of Year - month - day as we use in SQL
2. If the month is 9, it needs to be set as 09 not 9 simply. So it applies for day field also.

Please follow the fiddle link for demo:

var now = new Date();

var day = ("0" + now.getDate()).slice(-2);
var month = ("0" + (now.getMonth() + 1)).slice(-2);

var today = now.getFullYear()+"-"+(month)+"-"+(day) ;

$('#datePicker').val(today);

I think you can use thread like demon-thread for reading your input and your output reader will already be in while loop in main thread so you can read and write at same time.You can modify your program like this:

Thread T=new Thread(new Runnable() {

    @Override
    public void run() {
        while(true)
        {
            String input = scan.nextLine();
            input += "\n";
            try {
                writer.write(input);
                writer.flush();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }

    }
} );
T.start();

and you can reader will be same as above i.e.

while ((line = reader.readLine ()) != null) {
    System.out.println ("Stdout: " + line);
}

make your writer as final otherwise it wont be able to accessible by inner class.

You can create dropdown title | label with selected, hidden and style for old or unsupported device.

<select name="city" >
<option selected hidden style="display:none">What is your city</option>
   <option value="1">Sydney</option>
   <option value="2">Melbourne</option>
   <option value="3">Cromwell</option>
   <option value="4">Queenstown</option>
</select>

To get cookies expire time, use this simple method.

<?php

//#############PART 1#############
//expiration time (a*b*c*d) <- change D corresponding to number of days for cookie expiration
$time = time()+(60*60*24*365);
$timeMemo = (string)$time;

//sets cookie with expiration time defined above
setcookie("testCookie", "" . $timeMemo . "", $time);

//#############PART 2#############
//this function will convert seconds to days.
function secToDays($sec){

    return ($sec / 60 / 60 / 24);

}
//checks if cookie is set and prints out expiration time in days
if(isset($_COOKIE['testCookie'])){

    echo "Cookie is set<br />";
    if(round(secToDays((intval($_COOKIE['testCookie']) - time())),1) < 1){
        echo "Cookie will expire today.";
    }else{
        echo "Cookie will expire in " . round(secToDays((intval($_COOKIE['testCookie']) - time())),1) . " day(s)";
    }

}else{
    echo "not set...";
}

?>

You need to keep Part 1 and Part 2 in different files, otherwise you will get the same expire date everytime.

I know it's coming late but for those people who want to implement it purely using the JavaScript , here's how you can do it:

1. Get the reference to the current tr which is clicked.
2. Make a new tr DOM element.
3. Add it to the referred tr parent node.

HTML:

<table>
     <tr>
                    <td>
                        <button id="0" onclick="addRow()">Expand</button>
                    </td>
                    <td>abc</td>
                    <td>abc</td>
                    <td>abc</td>
                    <td>abc</td>
     </tr>

     <tr>
                    <td>
                        <button id="1" onclick="addRow()">Expand</button>
                    </td>
                    <td>abc</td>
                    <td>abc</td>
                    <td>abc</td>
                    <td>abc</td>
     </tr>
     <tr>
                    <td>
                        <button id="2" onclick="addRow()">Expand</button>
                    </td>
                    <td>abc</td>
                    <td>abc</td>
                    <td>abc</td>
                    <td>abc</td>
     </tr>

In JavaScript:

function addRow() {
        var evt = event.srcElement.id;
        var btn_clicked = document.getElementById(evt);
        var tr_referred = btn_clicked.parentNode.parentNode;
        var td = document.createElement('td');
        td.innerHTML = 'abc';
        var tr = document.createElement('tr');
        tr.appendChild(td);
        tr_referred.parentNode.insertBefore(tr, tr_referred.nextSibling);
        return tr;
    }

This will add the new table row exactly below the row on which the button is clicked.

You can use below class to read list of objects. It contains static method to read a list with some specific object type. It is included Jdk8Module changes which provide new time class supports too. It is a clean and generic class.

List<Student> students = JsonMapper.readList(jsonString, Student.class);

Generic JsonMapper class:

import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.datatype.jdk8.Jdk8Module;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;

import java.io.IOException;
import java.util.*;

import java.util.Collection;

public class JsonMapper {

    public static <T> List<T> readList(String str, Class<T> type) {
        return readList(str, ArrayList.class, type);
    }

    public static <T> List<T> readList(String str, Class<? extends Collection> type, Class<T> elementType) {
        final ObjectMapper mapper = newMapper();
        try {
            return mapper.readValue(str, mapper.getTypeFactory().constructCollectionType(type, elementType));
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }

    private static ObjectMapper newMapper() {
        final ObjectMapper mapper = new ObjectMapper();
        mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        mapper.registerModule(new JavaTimeModule());
        mapper.registerModule(new Jdk8Module());
        return mapper;
    }
}

I answer this coming from a component-based architecture, where an organisation may be running many components that may rely on each other. During a propagating failure, logging levels should help to identify both which components are affected and which are a root cause.

• ERROR - This component has had a failure and the cause is believed to be internal (any internal, unhandled exception, failure of encapsulated dependency... e.g. database, REST example would be it has received a 4xx error from a dependency). Get me (maintainer of this component) out of bed.

• WARN - This component has had a failure believed to be caused by a dependent component (REST example would be a 5xx status from a dependency). Get the maintainers of THAT component out of bed.

• INFO - Anything else that we want to get to an operator. If you decide to log happy paths then I recommend limiting to 1 log message per significant operation (e.g. per incoming http request).

For all log messages be sure to log useful context (and prioritise on making messages human readable/useful rather than having reams of "error codes")

• DEBUG (and below) - Shouldn't be used at all (and certainly not in production). In development I would advise using a combination of TDD and Debugging (where necessary) as opposed to polluting code with log statements. In production, the above INFO logging, combined with other metrics should be sufficient.

A nice way to visualise the above logging levels is to imagine a set of monitoring screens for each component. When all running well they are green, if a component logs a WARNING then it will go orange (amber) if anything logs an ERROR then it will go red.

In the event of an incident you should have one (root cause) component go red and all the affected components should go orange/amber.

"use strict";

Basically it enables the strict mode.

Strict Mode is a feature that allows you to place a program, or a function, in a "strict" operating context. In strict operating context, the method form binds this to the objects as before. The function form binds this to undefined, not the global set objects.

As per your comments you are telling some differences will be there. But it's your assumption. The Node.js code is nothing but your JavaScript code. All Node.js code are interpreted by the V8 JavaScript engine. The V8 JavaScript Engine is an open source JavaScript engine developed by Google for Chrome web browser.

So, there will be no major difference how "use strict"; is interpreted by the Chrome browser and Node.js.

Please read what is strict mode in JavaScript.

For more information:

1. Strict mode
2. ECMAScript 5 Strict mode support in browsers
3. Strict mode is coming to town
4. Compatibility table for strict mode
5. Stack Overflow questions: what does 'use strict' do in JavaScript & what is the reasoning behind it

ECMAScript 6 Code & strict mode. Following is brief from the specification:

10.2.1 Strict Mode Code

An ECMAScript Script syntactic unit may be processed using either unrestricted or strict mode syntax and semantics. Code is interpreted as strict mode code in the following situations:

• Global code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive (see 14.1.1).
• Module code is always strict mode code.
• All parts of a ClassDeclaration or a ClassExpression are strict mode code.
• Eval code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive or if the call to eval is a direct eval (see 12.3.4.1) that is contained in strict mode code.
• Function code is strict mode code if the associated FunctionDeclaration, FunctionExpression, GeneratorDeclaration, GeneratorExpression, MethodDefinition, or ArrowFunction is contained in strict mode code or if the code that produces the value of the function’s [[ECMAScriptCode]] internal slot begins with a Directive Prologue that contains a Use Strict Directive.
• Function code that is supplied as the arguments to the built-in Function and Generator constructors is strict mode code if the last argument is a String that when processed is a FunctionBody that begins with a Directive Prologue that contains a Use Strict Directive.

Additionally if you are lost on what features are supported by your current version of Node.js, this node.green can help you (leverages from the same data as kangax).

System.IO.File.Copy(oldPathAndName, newPathAndName);

You can sum up the values of a BigDecimal stream using a reusable Collector named summingUp:

BigDecimal sum = bigDecimalStream.collect(summingUp());

The Collector can be implemented like this:

public static Collector<BigDecimal, ?, BigDecimal> summingUp() {
    return Collectors.reducing(BigDecimal.ZERO, BigDecimal::add);
}

Sometimes it may be required to execute the update atomically that is using one update request to the database without reading it first.

Also get-set attribute-save may cause problems if such updates may be done concurrently or if you need to set the new value based on the old field value.

In such cases query expressions together with update may by useful:

TemperatureData.objects.filter(id=1).update(value=F('value') + 1)

The javax namespace is usually (that's a loaded word) used for standard extensions, currently known as optional packages. The standard extensions are a subset of the non-core APIs; the other segment of the non-core APIs obviously called the non-standard extensions, occupying the namespaces like com.sun.* or com.ibm.. The core APIs take up the java. namespace.

Not everything in the Java API world starts off in core, which is why extensions are usually born out of JSR requests. They are eventually promoted to core based on 'wise counsel'.

The interest in this nomenclature, came out of a faux pas on Sun's part - extensions could have been promoted to core, i.e. moved from javax.* to java.* breaking the backward compatibility promise. Programmers cried hoarse, and better sense prevailed. This is why, the Swing API although part of the core, continues to remain in the javax.* namespace. And that is also how packages get promoted from extensions to core - they are simply made available for download as part of the JDK and JRE.

If you want to reload after view change you need to

$state.reload('state',{reload:true});

If you want to make that view the new "root", you can tell ionic that the next view it's gonna be the root

 $ionicHistory.nextViewOptions({ historyRoot: true });
 $state.go('app.xxx');
 return;

If you want to make your controllers reload after each view change

app.config(function ($stateProvider, $urlRouterProvider, $ionicConfigProvider) {

$ionicConfigProvider.views.maxCache(0);

As an alternative to using UsedRange or providing an explicit range address, the AutoFilter.Range property can also specify the affected range.

ActiveSheet.AutoFilter.Range.Offset(1,0).Rows.SpecialCells(xlCellTypeVisible).Delete(xlShiftUp)

As used here, Offset causes the first row after the AutoFilter range to also be deleted. In order to avoid that, I would try using .Resize() after .Offset().

Try this. It works for me:

yarn run lint --fix

or

npm run lint -- --fix

Java 8

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");

LocalDateTime dateTime1= LocalDateTime.parse("2014-11-25 19:00:00", formatter);
LocalDateTime dateTime2= LocalDateTime.parse("2014-11-25 16:00:00", formatter);

long diffInMilli = java.time.Duration.between(dateTime1, dateTime2).toMillis();
long diffInSeconds = java.time.Duration.between(dateTime1, dateTime2).getSeconds();
long diffInMinutes = java.time.Duration.between(dateTime1, dateTime2).toMinutes();

You can try this if you want to override

var newArray= [444,555,666];
var oldArray =[11,22,33];
oldArray.forEach((name, index) => oldArray [index] = newArray[index]);
console.log(newArray);

Having just gone round the internet to read up on this and the options in Spring I'd second Luke's answer, use BCrypt (it's mentioned in the source code at Spring).

The best resource I found to explain why to hash/salt and why use BCrypt is a good choice is here: Salted Password Hashing - Doing it Right.

viewDidLoad is things you have to do once. viewWillAppear gets called every time the view appears. You should do things that you only have to do once in viewDidLoad - like setting your UILabel texts. However, you may want to modify a specific part of the view every time the user gets to view it, e.g. the iPod application scrolls the lyrics back to the top every time you go to the "Now Playing" view.

However, when you are loading things from a server, you also have to think about latency. If you pack all of your network communication into viewDidLoad or viewWillAppear, they will be executed before the user gets to see the view - possibly resulting a short freeze of your app. It may be good idea to first show the user an unpopulated view with an activity indicator of some sort. When you are done with your networking, which may take a second or two (or may even fail - who knows?), you can populate the view with your data. Good examples on how this could be done can be seen in various twitter clients. For example, when you view the author detail page in Twitterrific, the view only says "Loading..." until the network queries have completed.

To use an image for body background in CSS

body {
  background-image: url("image.jpg");
}

This is improved @Vicky solution - it has clearInterval() added so it prevents a loop of reloading if the redirect takes too long:

                            $(document).ready(function () {
                                var myTimer = window.setInterval(function () {
                                    var timeLeft = $("#countdown").html();
                                    if (eval(timeLeft) == 0) {
                                        console.log('Now redirecting');
                                        clearInterval(myTimer);
                                        window.location = ("@Html.Raw(HttpUtility.HtmlDecode(redirectUrl))");
                                    } else {
                                        $("#countdown").html(eval(timeLeft) - eval(1));
                                    }
                                }, 1000);
                            });

Use:

echo %time% & dir & echo %time%

This is, from memory, equivalent to the semi-colon separator in bash and other UNIXy shells.

There's also && (or ||) which only executes the second command if the first succeeded (or failed), but the single ampersand & is what you're looking for here.

That's likely to give you the same time however since environment variables tend to be evaluated on read rather than execute.

You can get round this by turning on delayed expansion:

pax> cmd /v:on /c "echo !time! & ping 127.0.0.1 >nul: & echo !time!"
15:23:36.77
15:23:39.85

That's needed from the command line. If you're doing this inside a script, you can just use setlocal:

@setlocal enableextensions enabledelayedexpansion
@echo off
echo !time! & ping 127.0.0.1 >nul: & echo !time!
endlocal

To check for an empty QueryString you should use Request.QueryString.HasKeys property.

To check if the key is present: Request.QueryString.AllKeys.Contains()

Then you can get ist's Value and do any other check you want, such as isNullOrEmpty, etc.

Here's the best solution I've found: http://jsfiddle.net/yWnZ2/446/ Works in Chrome, Firefox, Safari, IE8-11 & Edge.

If you have a declared height (height: 1em, height: 50%, etc.) or it's an element where the browser knows the height (img, svg, or canvas for example), then all you need for vertical centering is this:

.message {
    position: absolute;
    top: 0; bottom: 0; left: 0; right: 0;
    margin: auto;
}

You'll usually want to specify a width or max-width so the content doesn't stretch the whole length of the screen/container.

If you're using this for a modal that you want always centered in the viewport overlapping other content, use position: fixed; for both elements instead of position: absolute. http://jsfiddle.net/yWnZ2/445/

Here's a more complete writeup: http://codepen.io/shshaw/pen/gEiDt

Update log4j.properties to include:

log4j.logger.httpclient.wire.header=WARN
log4j.logger.httpclient.wire.content=WARN

Note that if Log4j library is not installed, HttpClient (and therefore JWebUnit) will use logback. In this situation, create or edit logback.xml to include:

<configuration>
    <logger name="org.apache" level="WARN" />
    <logger name="httpclient" level="WARN" /> 
</configuration>

Setting the log level to WARN with Log4j using the package name org.apache.commons.httpclient in log4j.properties will not work as expected:

log4j.logger.org.apache.commons.httpclient=WARN

This is because the source for HttpClient (v3.1) uses the following log names:

public static Wire HEADER_WIRE = new Wire(LogFactory.getLog("httpclient.wire.header"));
public static Wire CONTENT_WIRE = new Wire(LogFactory.getLog("httpclient.wire.content"));

Readin file with file inputstream and append file content to string.

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;

public class CopyOffileInputStream {

    public static void main(String[] args) {

        //File file = new File("./store/robots.txt");
        File file = new File("swingloggingsscce.log");

        FileInputStream fis = null;
        String str = "";

        try {
            fis = new FileInputStream(file);
            int content;
            while ((content = fis.read()) != -1) {
                // convert to char and display it
                str += (char) content;
            }

            System.out.println("After reading file");
            System.out.println(str);

        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                if (fis != null)
                    fis.close();
            } catch (IOException ex) {
                ex.printStackTrace();
            }
        }
    }
}

You can use Response to return any http status code.

> from flask import Response
> return Response("{'a':'b'}", status=201, mimetype='application/json')

I think the Class on img tag is better when You use the same style in different structure on Your site. You have to decide when you write less line of CSS code and HTML is more readable.

Content-Type: application/json is just the content header. The content header is just information about the type of returned data, ex::JSON,image(png,jpg,etc..),html.

Keep in mind, that JSON in JavaScript is an array or object. If you want to see all the data, use console.log instead of alert:

alert(response.text); // Will alert "[object Object]" string
console.log(response.text); // Will log all data objects

If you want to alert the original JSON content as a string, then add single quotation marks ('):

echo "'" . json_encode(array('text' => 'omrele')) . "'";
// alert(response.text) will alert {"text":"omrele"}

Do not use double quotes. It will confuse JavaScript, because JSON uses double quotes on each value and key:

echo '<script>var returndata=';
echo '"' . json_encode(array('text' => 'omrele')) . '"';
echo ';</script>';

// It will return the wrong JavaScript code:
<script>var returndata="{"text":"omrele"}";</script>

It's very easy.

Default constructors -- public constructors with out arguments (either declared or implied) -- are inherited by default. You can try the following code for an example of this:

public class CtorTest {
    public static void main(String[] args) {
        final Sub sub = new Sub();
        System.err.println("Finished.");
    }

    private static class Base {
        public Base() {
            System.err.println("In Base ctor");
        }
    }

    private static class Sub extends Base {
        public Sub() {
            System.err.println("In Sub ctor");
        }
    }
}

If you want to explicitly call a constructor from a super class, you need to do something like this:

public class Ctor2Test {
    public static void main(String[] args) {
        final Sub sub = new Sub();
        System.err.println("Finished.");
    }

    private static class Base {
        public Base() {
            System.err.println("In Base ctor");
        }

        public Base(final String toPrint) {
            System.err.println("In Base ctor.  To Print: " + toPrint);
        }
    }

    private static class Sub extends Base {
        public Sub() {
            super("Hello World!");
            System.err.println("In Sub ctor");
        }
    }
}

The only caveat is that the super() call must come as the first line of your constructor, else the compiler will get mad at you.

If the data in your database is POSTED from HTML form TextArea controls, different browsers use different New Line characters:

Firefox separates lines with CHR(10) only

Internet Explorer separates lines with CHR(13) + CHR(10)

Apple (pre-OSX) separates lines with CHR(13) only

So you may need something like:

set col_name = replace(replace(col_name, CHR(13), ''), CHR(10), '')

Its because the gradle is not synced because of many reasons.

Go to project folder and remove .gradle folder and start sync. It will work

I have done this using LINQ:

var oCSP = (from P in db.Products select new { P.ProductName });

string joinedString = string.Join(",", oCSP.Select(p => p.ProductName));

This can't be done with pure HTML.

However if you have access to PHP on the Apache server (you tagged the post "apache") it can be done easilly - se the PHP glob function. If not - you might try Server Side Include - it's an Apache thing, and I don't know much about it.

The inner finally is executed prior to throwing the exception to the outer block.

public class TryCatchFinally {

  public static void main(String[] args) throws Exception {

    try{
        System.out.println('A');
        try{
            System.out.println('B');
            throw new Exception("threw exception in B");
        }
        finally
        {
            System.out.println('X');
        }
        //any code here in the first try block 
        //is unreachable if an exception occurs in the second try block
    }
    catch(Exception e)
    {
        System.out.println('Y');
    }
    finally
    {
        System.out.println('Z');
    }
  }
}

Results in

A
B
X
Y
Z

Although this is an old question, I had the same question when using the Standard console version. The answer can be found in the Debian Live manual under the section 10.1 Customizing the live user. It says:

It is also possible to change the default username "user" and the default password "live".

I tried the username user and password live and it did work. If you want to run commands as root you can preface each command with sudo

There is an easy way

Instead of /pagename/ use index.php/pagename/ or if you don't use permalinks do the following :

Post

index.php?p=123

Page

index.php?page_id=42

Category

index.php?cat=7

More information here : http://codex.wordpress.org/Linking_Posts_Pages_and_Categories

list.ToArray()

Will do the tric. See here for details.

foreach(preg_split('~[\r\n]+~', $text) as $line){
    if(empty($line) or ctype_space($line)) continue; // skip only spaces
    // if(!strlen($line = trim($line))) continue; // or trim by force and skip empty
    // $line is trimmed and nice here so use it
}

^ this is how you break lines properly, cross-platform compatible with Regexp :)

Your PersonSheets has a property int Id, Id isn't in the post, so modelbinding fails. Make Id nullable (int?) or send atleast Id = 0 with the POst .

This has gotten a good answer but decided to expand a bit:

You can't get your application accepted to AppStore without reading Apple's iOS Human Interface Guidelines well. (they retain the right to reject you for doing anything against them) The section "Don't Quit Programmatically" http://developer.apple.com/library/ios/#DOCUMENTATION/UserExperience/Conceptual/MobileHIG/UEBestPractices/UEBestPractices.html is an exact guideline in how you should treat in this case.

If you ever have a problem with Apple platform you can't easily find a solution for, consult HIG. It's possible Apple simply doesn't want you to do it and they usually (I'm not Apple so I can't guarantee always) do say so in their documentation.

From your SQL Server Management Studio, you open Object Explorer, go to your database where you want to load the data into, right click, then pick Tasks > Import Data.

This opens the Import Data Wizard, which typically works pretty well for importing from Excel. You can pick an Excel file, pick what worksheet to import data from, you can choose what table to store it into, and what the columns are going to be. Pretty flexible indeed.

You can run this as a one-off, or you can store it as a SQL Server Integration Services (SSIS) package into your file system, or into SQL Server itself, and execute it over and over again (even scheduled to run at a given time, using SQL Agent).

Update: yes, yes, yes, you can do all those things you keep asking - have you even tried at least once to run that wizard??

OK, here it comes - step by step:

Step 1: pick your Excel source

Step 2: pick your SQL Server target database

Step 3: pick your source worksheet (from Excel) and your target table in your SQL Server database; see the "Edit Mappings" button!

Step 4: check (and change, if needed) your mappings of Excel columns to SQL Server columns in the table:

Step 5: if you want to use it later on, save your SSIS package to SQL Server:

Step 6: - success! This is on a 64-bit machine, works like a charm - just do it!!

Can't you just change working directory within the python script using os.chdir(target)? I agree, I can't see any way of doing it from the jar command itself.

If you don't want to permanently change directory, then store the current directory (using os.getcwd())in a variable and change back afterwards.

You have to set the height for the parents (container and child) explicitly, here is another work-around (if you don't want to set that height explicitly):

.child {
  width: 30px;
  background-color: red;
  display: table-cell;
  vertical-align: top;
  position:relative;
}

.content {
  position:absolute;
  top:0;
  bottom:0;
  width:100%;
  background-color: blue;
}

Fiddle

Simply write one line in the constructor:

setResizable(false);

This will make it impossible to resize the frame.

you must be using old version of wget i had same issue. i was using wget 1.12.so to solve this issue there are 2 way: Update wget or use curl

curl -LO 'https://example.com/filename.tar.gz'

You can use Bundle to get data :

Bundle extras = intent.getExtras();
String data = extras.getString("data"); // use your key 

And again you can opass this data to next activity :

 Intent intent = new Intent(this, next_Activity.class);
   intent.putExtra("data", data);
   startActivity(intent);

This prints 10 lines of trailing context after matching lines

grep -i "my_regex" -A 10

If you need to print 10 lines of leading context before matching lines,

grep -i "my_regex" -B 10

And if you need to print 10 lines of leading and trailing output context.

grep -i "my_regex" -C 10

Example

user@box:~$ cat out 
line 1
line 2
line 3
line 4
line 5 my_regex
line 6
line 7
line 8
line 9
user@box:~$

Normal grep

user@box:~$ grep my_regex out 
line 5 my_regex
user@box:~$ 

Grep exact matching lines and 2 lines after

user@box:~$ grep -A 2 my_regex out   
line 5 my_regex
line 6
line 7
user@box:~$ 

Grep exact matching lines and 2 lines before

user@box:~$ grep -B 2 my_regex out  
line 3
line 4
line 5 my_regex
user@box:~$ 

Grep exact matching lines and 2 lines before and after

user@box:~$ grep -C 2 my_regex out  
line 3
line 4
line 5 my_regex
line 6
line 7
user@box:~$ 

Reference: manpage grep

-A num
--after-context=num

    Print num lines of trailing context after matching lines.
-B num
--before-context=num

    Print num lines of leading context before matching lines.
-C num
-num
--context=num

    Print num lines of leading and trailing output context.

Note: This solution is better for older versions of JSTL. For versions greater then 1.1 I recommend using fn:length(MyBean.somelist) as suggested by Bill James.

This article has some more detailed information, including another possible solution;

The problem is that we are trying to invoke the list's size method (which is a valid LinkedList method), but it's not a JavaBeans-compliant getter method, so the expression list.size-1 cannot be evaluated.

There are two ways to address this dilemma. First, you can use the RT Core library, like this:

<c_rt:out value='<%= list[list.size()-1] %>'/>

Second, if you want to avoid Java code in your JSP pages, you can implement a simple wrapper class that contains a list and provides access to the list's size property with a JavaBeans-compliant getter method. That bean is listed in Listing 2.25.

The problem with c_rt method is that you need to get the variable from request manually, because it doesn't recognize it otherwise. At this point you are putting in a lot of code for what should be built in functionality. This is a GIANT flaw in the EL.

I ended up using the "wrapper" method, here is the class for it;

public class CollectionWrapper {

    Collection collection;

    public CollectionWrapper(Collection collection) {
        this.collection = collection;
    }

    public Collection getCollection() {
        return collection;
    }

    public int getSize() {
        return collection.size();
    }
}

A third option that no one has mentioned yet is to put your list size into the model (assuming you are using MVC) as a separate attribute. So in your model you would have "someList" and then "someListSize". That may be simplest way to solve this issue.

You could achieve this quite easily with jQuery by registering for the click event of the anchors (with class="movie") and using the .load() method to send an AJAX request and replace the contents of the summary div:

$(function() {
    $('.movie').click(function() {
        $('#summary').load(this.href);

        // it's important to return false from the click
        // handler in order to cancel the default action
        // of the link which is to redirect to the url and
        // execute the AJAX request
        return false;
    });
});

         string json = @"{
            'Name': 'Wide Web',
            'Url': 'www.wideweb.com.br'}";

        JavaScriptSerializer jsonSerializer = new JavaScriptSerializer();
        dynamic j = jsonSerializer.Deserialize<dynamic>(json);
        string name = j["Name"].ToString();
        string url = j["Url"].ToString();

Here it fails at Array.apply(null, new Array(1000000)) and not the .map call.

All functions arguments must fit on callstack(at least pointers of each argument), so in this they are too many arguments for the callstack.

You need to the understand what is call stack.

Stack is a LIFO data structure, which is like an array that only supports push and pop methods.

Let me explain how it works by a simple example:

function a(var1, var2) {
    var3 = 3;
    b(5, 6);
    c(var1, var2);
}
function b(var5, var6) {
    c(7, 8);
}
function c(var7, var8) {
}

When here function a is called, it will call b and c. When b and c are called, the local variables of a are not accessible there because of scoping roles of Javascript, but the Javascript engine must remember the local variables and arguments, so it will push them into the callstack. Let's say you are implementing a JavaScript engine with the Javascript language like Narcissus.

We implement the callStack as array:

var callStack = [];

Everytime a function called we push the local variables into the stack:

callStack.push(currentLocalVaraibles);

Once the function call is finished(like in a, we have called b, b is finished executing and we must return to a), we get back the local variables by poping the stack:

currentLocalVaraibles = callStack.pop();

So when in a we want to call c again, push the local variables in the stack. Now as you know, compilers to be efficient define some limits. Here when you are doing Array.apply(null, new Array(1000000)), your currentLocalVariables object will be huge because it will have 1000000 variables inside. Since .apply will pass each of the given array element as an argument to the function. Once pushed to the call stack this will exceed the memory limit of call stack and it will throw that error.

Same error happens on infinite recursion(function a() { a() }) as too many times, stuff has been pushed to the call stack.

Note that I'm not a compiler engineer and this is just a simplified representation of what's going on. It really is more complex than this. Generally what is pushed to callstack is called stack frame which contains the arguments, local variables and the function address.

if you want to set value than you can do the same in some function on click or on some event fire.

also you can get value using ViewChild using local variable like this

<input type='text' id='loginInput' #abc/>

and get value like this

this.abc.nativeElement.value

here is working example

Update

okay got it , you have to use ngAfterViewInit method of angualr2 for the same like this

ngAfterViewInit(){
    document.getElementById('loginInput').value = '123344565';
  }

ngAfterViewInit will not throw any error because it will render after template loading

In answer to your first question, there's no parameter substitution because you've put the delimiter in quotes - the bash manual says:

The format of here-documents is:

      <<[-]word
              here-document
      delimiter

No parameter expansion, command substitution, arithmetic expansion, or pathname expansion is performed on word. If any characters in word are quoted, the delimiter is the result of quote removal on word, and the lines in the here-document are not expanded. If word is unquoted, all lines of the here-document are subjected to parameter expansion, command substitution, and arithmetic expansion. [...]

If you change your first example to use <<EOF instead of << "EOF" you'll find that it works.

In your second example, the shell invokes sudo only with the parameter cat, and the redirection applies to the output of sudo cat as the original user. It'll work if you try:

sudo sh -c "cat > /path/to/outfile" <<EOT
my text...
EOT

Use the built-in time keyword:

$ help time

time: time [-p] PIPELINE
    Execute PIPELINE and print a summary of the real time, user CPU time,
    and system CPU time spent executing PIPELINE when it terminates.
    The return status is the return status of PIPELINE.  The `-p' option
    prints the timing summary in a slightly different format.  This uses
    the value of the TIMEFORMAT variable as the output format.

Example:

$ time sleep 2

real    0m2.009s
user    0m0.000s
sys     0m0.004s

Converting to double can be done by casting an int to a double:

You can convert an int to a double by using this mechnism like so:

int i = 3; // i is 3
double d = (double) i; // d = 3.0

Alternative (using Java's automatic type recognition):

double d = 1.0 * i; // d = 3.0

Implementing this in your code would be something like:

double firstSolution = ((double)(b1 * a22 - b2 * a12) / (double)(a11 * a22 - a12 * a21));
double secondSolution = ((double)(b2 * a11 - b1 * a21) / (double)(a11 * a22 - a12 * a21));

Alternatively you can use a hard-parameter of type double (1.0) to have java to the work for you, like so:

double firstSolution = ((1.0 * (b1 * a22 - b2 * a12)) / (1.0 * (a11 * a22 - a12 * a21)));
double secondSolution = ((1.0 * (b2 * a11 - b1 * a21)) / (1.0 * (a11 * a22 - a12 * a21)));

Good luck.

If you're rolling your own I'd highly recommend looking at http://effbot.org/zone/element-soap.htm.

If you want to create your own server using a ServerSocket, you can just have it pick a free port for you:

  ServerSocket serverSocket = new ServerSocket(0);
  int port = serverSocket.getLocalPort();

Other server implementations typically have similar support. Jetty for example picks a free port unless you explicitly set it:

  Server server = new Server();
  ServerConnector connector = new ServerConnector(server);
  // don't call: connector.setPort(port);
  server.addConnector(connector);
  server.start();
  int port = connector.getLocalPort();

if your not satisfied with the answers above then use this

    * {margin: 0;padding: 0;}

    html
    {
        height: 100%;
    }

    body
    {
        background-image: url("background.png");
        background-repeat: no-repeat;
        background-position: center center;
        background-size: 80%;
    }

I ran into this same problem when I wanted to enable SSL to a project hosted on IIS 8. Finally the tool I used was OpenSSL, after many days fighting with makecert commands.The certificate is generated in Debian, but I could import it seamlessly into IIS 7 and 8.

Download the OpenSSL compatible with your OS and this configuration file. Set the configuration file as default configuration of OpenSSL.

First we will generate the private key and certificate of Certification Authority (CA). This certificate is to sign the certificate request (CSR).

You must complete all fields that are required in this process.

1. openssl req -new -x509 -days 3650 -extensions v3_ca -keyout root-cakey.pem -out root-cacert.pem -newkey rsa:4096

You can create a configuration file with default settings like this: Now we will generate the certificate request, which is the file that is sent to the Certification Authorities.

The Common Name must be set the domain of your site, for example: public.organization.com.

2. openssl req -new -nodes -out server-csr.pem -keyout server-key.pem -newkey rsa:4096

Now the certificate request is signed with the generated CA certificate.

3. openssl x509 -req -days 365 -CA root-cacert.pem -CAkey root-cakey.pem -CAcreateserial -in server-csr.pem -out server-cert.pem

The generated certificate must be exported to a .pfx file that can be imported into the IIS.

4. openssl pkcs12 -export -out server-cert.pfx -inkey server-key.pem -in server-cert.pem -certfile root-cacert.pem -name "Self Signed Server Certificate"

In this step we will import the certificate CA.

5. In your server must import the CA certificate to the Trusted Root Certification Authorities, for IIS can trust the certificate to be imported. Remember that the certificate to be imported into the IIS, has been signed with the certificate of the CA.

   • Open Command Prompt and type mmc.
   • Click on File.
   • Select Add/Remove Snap in....
   • Double click on Certificates.
   • Select Computer Account and Next ->.
   • Select Local Computer and Finish.
   • Ok.
   • Go to Certificates -> Trusted Root Certification Authorities -> Certificates, rigth click on Certificates and select All Tasks -> Import ...

• Select Next -> Browse ...
• You must select All Files to browse the location of root-cacert.pem file.
• Click on Next and select Place all certificates in the following store: Trusted Root Certification Authorities.
• Click on Next and Finish.

With this step, the IIS trust on the authenticity of our certificate.

6. In our last step we will import the certificate to IIS and add the binding site.

   • Open Internet Information Services (IIS) Manager or type inetmgr on command prompt and go to Server Certificates.
   • Click on Import....
   • Set the path of .pfx file, the passphrase and Select certificate store on Web Hosting.

• Click on OK.

• Now go to your site on IIS Manager and select Bindings... and Add a new binding.

• Select https as the type of binding and you should be able to see the imported certificate.

• Click on OK and all is done.

Beside list comprehension, you can try map

>>> map(lambda x: str.replace(x, "[br]", "<br/>"), words)
['how', 'much', 'is<br/>', 'the', 'fish<br/>', 'no', 'really']

If you get Cannot redirect after HTTP headers have been sent then try this below code.

HttpContext.Current.Server.ClearError();
// Response.Headers.Clear();
HttpContext.Current.Response.Redirect("/Home/Login",false);

You can include the Jython library in your Java Project. You can download the source code from the Jython project itself.

Jython does offers support for JSR-223 which basically lets you run a Python script from Java.

You can use a ScriptContext to configure where you want to send your output of the execution.

For instance, let's suppose you have the following Python script in a file named numbers.py:

for i in range(1,10):
    print(i)

So, you can run it from Java as follows:

public static void main(String[] args) throws ScriptException, IOException {

    StringWriter writer = new StringWriter(); //ouput will be stored here

    ScriptEngineManager manager = new ScriptEngineManager();
    ScriptContext context = new SimpleScriptContext();

    context.setWriter(writer); //configures output redirection
    ScriptEngine engine = manager.getEngineByName("python");
    engine.eval(new FileReader("numbers.py"), context);
    System.out.println(writer.toString()); 
}

And the output will be:

As long as your Python script is compatible with Python 2.5 you will not have any problems running this with Jython.

SET XACT_ABORT ON instructs SQL Server to rollback the entire transaction and abort the batch when a run-time error occurs. It covers you in cases like a command timeout occurring on the client application rather than within SQL Server itself (which isn't covered by the default XACT_ABORT OFF setting.)

Since a query timeout will leave the transaction open, SET XACT_ABORT ON is recommended in all stored procedures with explicit transactions (unless you have a specific reason to do otherwise) as the consequences of an application performing work on a connection with an open transaction are disastrous.

There's a really great overview on Dan Guzman's Blog,

I just saw this blog entry: Money vs. Decimal in SQL Server.

Which basically says that money has a precision issue...

declare @m money
declare @d decimal(9,2)

set @m = 19.34
set @d = 19.34

select (@m/1000)*1000
select (@d/1000)*1000

For the money type, you will get 19.30 instead of 19.34. I am not sure if there is an application scenario that divides money into 1000 parts for calculation, but this example does expose some limitations.

I think that this below is accurate and it may help. Feel free to correct it if you find any errors. I'm new at C.

char str[]  

1. array of values of type char, with its own address in memory
2. array of values of type char, with its own address in memory as many consecutive addresses as elements in the array

3. including termination null character '\0' &str, &str[0] and str, all three represent the same location in memory which is address of the first element of the array str

   char *strPtr = &str[0]; //declaration and initialization

alternatively, you can split this in two:

char *strPtr; strPtr = &str[0];

4. strPtr is a pointer to a char
5. strPtr points at array str
6. strPtr is a variable with its own address in memory
7. strPtr is a variable that stores value of address &str[0]
8. strPtr own address in memory is different from the memory address that it stores (address of array in memory a.k.a &str[0])
9. &strPtr represents the address of strPtr itself

I think that you could declare a pointer to a pointer as:

char **vPtr = &strPtr;  

declares and initializes with address of strPtr pointer

Alternatively you could split in two:

char **vPtr;
*vPtr = &strPtr

10. *vPtr points at strPtr pointer
11. *vPtr is a variable with its own address in memory
12. *vPtr is a variable that stores value of address &strPtr
13. final comment: you can not do str++, str address is a const, but you can do strPtr++

This may be an incorrect parameter to your SOAP call; look at the format of the parameter(s) in the 'data:' json section - this is the payload you are passing over - parameter and data wrapped in JSON format.

Google Chrome's debugging toolbar has some good tools to verify parameters and look at error messages - for example, start with the Console tab and click on the URL which errors or click on the network tab. You will want to view the message's headers, response etc...

Just download and install openSSH for windows. It is open source, and it makes your cmd ssh ready. A quick google search will give you a tutorial on how to install it, should you need it.

After it is installed you can just go ahead and generate your public key if you want to put in on a server. You generate it by running:

ssh-keygen -t rsa

After that you can just can just press enter, it will automatically assign a name for the key (example: id_rsa.pub)

You say that the matrices are the same dimensions, and yet you are trying to perform matrix multiplication on them. Multiplication of matrices with the same dimension is only possible if they are square. In your case, you get an assertion error, because the dimensions are not square. You have to be careful when multiplying matrices, as there are two possible meanings of multiply.

Matrix multiplication is where two matrices are multiplied directly. This operation multiplies matrix A of size [a x b] with matrix B of size [b x c] to produce matrix C of size [a x c]. In OpenCV it is achieved using the simple * operator:

C = A * B

Element-wise multiplication is where each pixel in the output matrix is formed by multiplying that pixel in matrix A by its corresponding entry in matrix B. The input matrices should be the same size, and the output will be the same size as well. This is achieved using the mul() function:

output = A.mul(B);

You can use json2csharp.com to Convert your json to object model

• Go to json2csharp.com
• Past your JSON in the Box.
• Clik on Generate.
• You will get C# Code for your object model
• Deserialize by var model = JsonConvert.DeserializeObject<RootObject>(json); using NewtonJson

Here, It will generate something like this:

public class MatrixModel
{
    public class Option
    {
        public string text { get; set; }
        public string selectedMarks { get; set; }
    }

    public class Model
    {
        public List<Option> options { get; set; }
        public int maxOptions { get; set; }
        public int minOptions { get; set; }
        public bool isAnswerRequired { get; set; }
        public string selectedOption { get; set; }
        public string answerText { get; set; }
        public bool isRangeType { get; set; }
        public string from { get; set; }
        public string to { get; set; }
        public string mins { get; set; }
        public string secs { get; set; }
    }

    public class Question
    {
        public int QuestionId { get; set; }
        public string QuestionText { get; set; }
        public int TypeId { get; set; }
        public string TypeName { get; set; }
        public Model Model { get; set; }
    }

    public class RootObject
    {
        public Question Question { get; set; }
        public string CheckType { get; set; }
        public string S1 { get; set; }
        public string S2 { get; set; }
        public string S3 { get; set; }
        public string S4 { get; set; }
        public string S5 { get; set; }
        public string S6 { get; set; }
        public string S7 { get; set; }
        public string S8 { get; set; }
        public string S9 { get; set; }
        public string S10 { get; set; }
        public string ScoreIfNoMatch { get; set; }
    }
}

Then you can deserialize as:

var model = JsonConvert.DeserializeObject<List<MatrixModel.RootObject>>(json);

It is a batch terminator, you can however change it to whatever you want

Assume that we need to view some data in command prompt which are coming from a database table. First we create a list. Team_Details is my property class.

    List<Team_Details> teamDetails = new List<Team_Details>();

Then you can connect to the database and do the data retrieving part and save it to the list as follows.

            string connetionString = "Data Source=.;Initial Catalog=your DB name;Integrated Security=True;MultipleActiveResultSets=True";
            using (SqlConnection conn = new SqlConnection(connetionString)){
            string getTeamDetailsQuery = "select * from Team";
            conn.Open();
            using (SqlCommand cmd = new SqlCommand(getTeamDetailsQuery, conn))
                    {
                        SqlDataReader rdr = cmd.ExecuteReader();
                    {
                        teamDetails.Add(new Team_Details
                        {
                            Team_Name = rdr.GetString(rdr.GetOrdinal("Team_Name")),
                            Team_Lead = rdr.GetString(rdr.GetOrdinal("Team_Lead")),
                        });
                    }

Then you can print this list in command prompt as follows.

foreach (Team_Details i in teamDetails)
                        {
                            Console.WriteLine(i.Team_Name);
                            Console.WriteLine(i.Team_Lead);
                        }

TLDR: It depends on what is most important - a tidy history or a true representation of the sequence of development

If a tidy history is the most important, then you would rebase first and then merge your changes, so it is clear exactly what the new code is. If you have already pushed your branch, don't rebase unless you can deal with the consequences.

If true representation of sequence is the most important, you would merge without rebasing.

Merge means: Create a single new commit that merges my changes into the destination. Note: This new commit will have two parents - the latest commit from your string of commits and the latest commit of the other branch you're merging.

Rebase means: Create a whole new series of commits, using my current set of commits as hints. In other words, calculate what my changes would have looked like if I had started making them from the point I'm rebasing on to. After the rebase, therefore, you might need to re-test your changes and during the rebase, you would possibly have a few conflicts.

Given this, why would you rebase? Just to keep the development history clear. Let's say you're working on feature X and when you're done, you merge your changes in. The destination will now have a single commit that would say something along the lines of "Added feature X". Now, instead of merging, if you rebased and then merged, the destination development history would contain all the individual commits in a single logical progression. This makes reviewing changes later on much easier. Imagine how hard you'd find it to review the development history if 50 developers were merging various features all the time.

That said, if you have already pushed the branch you're working on upstream, you should not rebase, but merge instead. For branches that have not been pushed upstream, rebase, test and merge.

Another time you might want to rebase is when you want to get rid of commits from your branch before pushing upstream. For example: Commits that introduce some debugging code early on and other commits further on that clean that code up. The only way to do this is by performing an interactive rebase: git rebase -i <branch/commit/tag>

UPDATE: You also want to use rebase when you're using Git to interface to a version control system that doesn't support non-linear history (Subversion for example). When using the git-svn bridge, it is very important that the changes you merge back into Subversion are a sequential list of changes on top of the most recent changes in trunk. There are only two ways to do that: (1) Manually re-create the changes and (2) Using the rebase command, which is a lot faster.

UPDATE 2: One additional way to think of a rebase is that it enables a sort of mapping from your development style to the style accepted in the repository you're committing to. Let's say you like to commit in small, tiny chunks. You have one commit to fix a typo, one commit to get rid of unused code and so on. By the time you've finished what you need to do, you have a long series of commits. Now let's say the repository you're committing to encourages large commits, so for the work you're doing, one would expect one or maybe two commits. How do you take your string of commits and compress them to what is expected? You would use an interactive rebase and squash your tiny commits into fewer larger chunks. The same is true if the reverse was needed - if your style was a few large commits, but the repository demanded long strings of small commits. You would use a rebase to do that as well. If you had merged instead, you have now grafted your commit style onto the main repository. If there are a lot of developers, you can imagine how hard it would be to follow a history with several different commit styles after some time.

UPDATE 3: Does one still need to merge after a successful rebase? Yes, you do. The reason is that a rebase essentially involves a "shifting" of commits. As I've said above, these commits are calculated, but if you had 14 commits from the point of branching, then assuming nothing goes wrong with your rebase, you will be 14 commits ahead (of the point you're rebasing onto) after the rebase is done. You had a branch before a rebase. You will have a branch of the same length after. You still need to merge before you publish your changes. In other words, rebase as many times as you want (again, only if you have not pushed your changes upstream). Merge only after you rebase.

Make sure R.layout.themechanger has no background color because by default the dialog has a default background color.

You also need to add dialog.getWindow().setBackgroundDrawable(newColorDrawable(Color.TRANSPARENT));

And finally

<style name="TransparentDialog">
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowTitleStyle">@null</item>
</style>

To implement that, it seems that you have to:

1. Create your model (user, role, permissions) and a way to retrieve permissions for a given user;
2. Define your own org.springframework.security.authentication.ProviderManager and configure it (set its providers) to a custom org.springframework.security.authentication.AuthenticationProvider. This last one should return on its authenticate method a Authentication, which should be setted with the org.springframework.security.core.GrantedAuthority, in your case, all the permissions for the given user.

The trick in that article is to have roles assigned to users, but, to set the permissions for those roles in the Authentication.authorities object.

For that I advise you to read the API, and see if you can extend some basic ProviderManager and AuthenticationProvider instead of implementing everything. I've done that with org.springframework.security.ldap.authentication.LdapAuthenticationProvider setting a custom LdapAuthoritiesPopulator, that would retrieve the correct roles for the user.

Hope this time I got what you are looking for. Good luck.

I suggest using global variables blurfrom and blurto. Then, configure all elements you care about to assign their position in the DOM to the variable blurfrom when they lose focus. Additionally, configure them so that gaining focus sets the variable blurto to their position in the DOM. Then, you could use another function altogether to analyze the blurfrom and blurto data.

I wrote an extension with method which removes all controllers between root and top, unless specified otherwise.

extension UINavigationController {
func removeControllers(between start: UIViewController?, end: UIViewController?) {
    guard viewControllers.count > 1 else { return }
    let startIndex: Int
    if let start = start {
        guard let index = viewControllers.index(of: start) else {
            return
        }
        startIndex = index
    } else {
        startIndex = 0
    }

    let endIndex: Int
    if let end = end {
        guard let index = viewControllers.index(of: end) else {
            return
        }
        endIndex = index
    } else {
        endIndex = viewControllers.count - 1
    }
    let range = startIndex + 1 ..< endIndex
    viewControllers.removeSubrange(range)
}

}

If you want to use range (for example: 2 to 5) you can just use

    let range = 2 ..< 5
    viewControllers.removeSubrange(range)

UPDATE wp_posts SET guid = replace(guid, 'http://olddomain.com','http://newdomain.com');

UPDATE wp_posts SET post_content = replace(post_content, 'http://olddomain.com', 'http://newdomain.com');

UPDATE wp_posts SET post_excerpt = replace(post_excerpt, 'http://olddomain.com', 'http://newdomain.com');

To get the key IDs (8 bytes, 16 hex digits), this is the command which worked for me in GPG 1.4.16, 2.1.18 and 2.2.19:

gpg --list-packets <key.asc | awk '$1=="keyid:"{print$2}'

To get some more information (in addition to the key ID):

gpg --list-packets <key.asc

To get even more information:

gpg --list-packets -vvv --debug 0x2 <key.asc

The command

gpg --dry-run --import <key.asc

also works in all 3 versions, but in GPG 1.4.16 it prints only a short (4 bytes, 8 hex digits) key ID, so it's less secure to identify keys.

Some commands in other answers (e.g. gpg --show-keys, gpg --with-fingerprint, gpg --import --import-options show-only) don't work in some of the 3 GPG versions above, thus they are not portable when targeting multiple versions of GPG.

Bravo for @user80168's solution (I'm still counting \'s !) but to avoid all the escaping involved with aliases and shells:

%~/ cat ~/bin/perlmod
perl -le'eval qq{require $ARGV[0]; } 
    ? print ( "Found $ARGV[0] Version: ", eval "$ARGV[0]->VERSION" ) 
    : print "Not installed" ' $1

works reasonably well.

Here might be the simplest and most "modern" approach, using Module::Runtime:

perl -MModule::Runtime=use_module -E '
     say "$ARGV[0] ", use_module($ARGV[0])->VERSION' DBI

This will give a useful error if the module is not installed.

Using -MModule::Runtime requires it to be installed (it is not a core module).

I have Xcode 10.1 and I can not run my application on my device with 12.2 iOS version.

The easiest solution for me was:

1. Go with finder at Xcode location
2. Right Click -> Show Package Contents
3. Contents -> Developer -> Platforms -> iPhoneOS.platform -> DeviceSupport
4. Here you find a list of supported version. Choose the most recent one and copy(In my case was 12.1 (16B91))
5. Paste in the same folder(DeviceSupport) and call it with the version you need.(In my case was 12.2 (16E227))
6. Close Xcode if you have it open
7. Reconnect device if it was connected
8. Open Xcode and build

If this trick does not working, you have to get the versions from the new Xcode version.

But you can try, saves a lot of time. Good luck!

EDIT: Or you can download your needed device support from here: https://github.com/iGhibli/iOS-DeviceSupport/tree/master/DeviceSupport

Best guess is you are on windows and your line ending settings are set for windows. See this topic: How to change line-ending settings

or use:

tr '\r\n' ' '

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

You can use readonly instead. Following would do the trick for you.

<input type="text" class="details-dialog" style="background-color: #bbbbbb" readonly>

But you need to note the following. Depends on your business requirement, you can use it.

A readonly element is just not editable, but gets sent when the according form submits. A disabled element isn't editable and isn't sent on submit.

Based on @Dave Syer, @kaliatech and @asmaier answers the springboot v2+ way would be:

public class StaticResourceConfiguration implements WebMvcConfigurer  {

  @Override
  public void addResourceHandlers(ResourceHandlerRegistry registry) {
    String myExternalFilePath = "file:///C:/temp/whatever/m/";

     registry.addResourceHandler("/m/**").addResourceLocations(myExternalFilePath);

  }

}

client = new OkHttpClient();

        Request request = new Request.Builder().header("authorization", token).url(url).build();
        MyWebSocketListener wsListener = new MyWebSocketListener(LudoRoomActivity.this);
        client.newWebSocket(request, wsListener);
        client.dispatcher().executorService().shutdown();

Use cacls command. See information here.

CACLS files /e /p {USERNAME}:{PERMISSION}

Where,

/p : Set new permission

/e : Edit permission and kept old permission as it is i.e. edit ACL instead of replacing it.

{USERNAME} : Name of user

{PERMISSION} : Permission can be:

R - Read

W - Write

C - Change (write)

F - Full control

For example grant Rocky Full (F) control with following command (type at Windows command prompt):

C:> CACLS files /e /p rocky:f

My favoured method for doing this looks something like:

<xsl:stylesheet>

<xsl:output method='text'/>

<xsl:variable name='newline'><xsl:text>
</xsl:text></xsl:variable>

<!-- note that the layout there is deliberate -->

...

</xsl:stylesheet>

Then, whenever you want to output a newline (perhaps in csv) you can output something like the following:

<xsl:value-of select="concat(elem1,elem2,elem3,$newline)" />

I've used this technique when outputting sql from xml input. In fact, I tend to create variables for commas, quotes and newlines.

2. Resolve this issue by updating the Target Framework in the project application settings.

For instance, In my case the project was compiling with .net framework version 4.5.1 but the dll which were referenced were compiled with the version 4.6.1. So have updated the my project version. I hope it works for you.

In practice, the most common reason for this happening seems to be that the .rnd file in your home directory is owned by root rather than your account. The quick fix:

sudo rm ~/.rnd

For more information, here's the entry from the OpenSSL FAQ:

Sometimes the openssl command line utility does not abort with a "PRNG not seeded" error message, but complains that it is "unable to write 'random state'". This message refers to the default seeding file (see previous answer). A possible reason is that no default filename is known because neither RANDFILE nor HOME is set. (Versions up to 0.9.6 used file ".rnd" in the current directory in this case, but this has changed with 0.9.6a.)

So I would check RANDFILE, HOME, and permissions to write to those places in the filesystem.

If everything seems to be in order, you could try running with strace and see what exactly is going on.

You can easily achieve what you want using the appendix package. Here's a sample file that shows you how. The key is the titletoc option when calling the package. It takes whatever value you've defined in \appendixname and the default value is Appendix.

While it may work on some platforms, be aware that platform.architecture is not always a reliable way to determine whether python is running in 32-bit or 64-bit. In particular, on some OS X multi-architecture builds, the same executable file may be capable of running in either mode, as the example below demonstrates. The quickest safe multi-platform approach is to test sys.maxsize on Python 2.6, 2.7, Python 3.x.

df=pd.read_csv("filename.csv" , parse_dates=["<column name>"])

type(df.<column name>)

example: if you want to convert day which is initially a string to a Timestamp in Pandas

df=pd.read_csv("weather_data2.csv" , parse_dates=["day"])

type(df.day)

The output will be pandas.tslib.Timestamp

There is a file in your git root directory named .gitignore. It's a file, not a command. You just need to insert the names of the files that you want to ignore, and they will automatically be ignored. For example, if you wanted to ignore all emacs autosave files, which end in ~, then you could add this line:

*~

If you want to remove the unwanted files from your branch, you can use git add -A, which "removes files that are no longer in the working tree".

Note: What I called the "git root directory" is simply the directory in which you used git init for the first time. It is also where you can find the .git directory.

Step-1 Need to find user details by using below query

SQL> select username, account_status from dba_users where username='BOB';

USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
BOB                            EXPIRED

Step-2 Get users password by using below query.

SQL>SELECT 'ALTER USER '|| name ||' IDENTIFIED BY VALUES '''|| spare4 ||';'|| password ||''';' FROM sys.user$ WHERE name='BOB';

ALTER USER BOB IDENTIFIED BY VALUES 'S:9BDD17811E21EFEDFB1403AAB1DD86AB481E;T:602E36430C0D8DF7E1E453;2F9933095143F432';

Step -3 Run Above alter query

SQL> ALTER USER BOB IDENTIFIED BY VALUES 'S:9BDD17811E21EFEDFB1403AAB1DD86AB481E;T:602E36430C0D8DF7E1E453;2F9933095143F432';
User altered.

Step-4 :Check users account status

SQL> select username, account_status from dba_users where username='BOB';
USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
BOB                            OPEN

Length of characters to be matched.

{n,m}  n <= length <= m
{n}    length == n
{n,}   length >= n

And by default, the engine is greedy to match this pattern. For example, if the input is 123456789, \d{2,5} will match 12345 which is with length 5.

If you want the engine returns when length of 2 matched, use \d{2,5}?

You will need to import the other file as a module like this:

import Math

If you don't want to prefix your Calculate function with the module name then do this:

from Math import Calculate

If you want to import all members of a module then do this:

from Math import *

Edit: Here is a good chapter from Dive Into Python that goes a bit more in depth on this topic.

First of all this is JavaScript and not C#

Then you cannot disable a div because it normally has no functionality. To disable a click event, you simply have to remove the event from the dom object. (bind and unbind)...

From the documentation:

The $.browser property is deprecated in jQuery 1.3, and its functionality may be moved to a team-supported plugin in a future release of jQuery.

So, yes, it is deprecated, but your existing implementations will continue to work. If the functionality is removed, it will likely be easily accessible using a plugin.

As to whether there is an alternative... The answer is "yes, probably". It is far, far better to do feature detection using $.support rather than browser detection: detect the actual feature you need, not the browser that provides it. Most important features that vary from browser to browser are detected with that.

Update 16 February 2013: In jQuery 1.9, this feature was removed (docs). It is far better not to use it. If you really, really must use its functionality, you can restore it with the jQuery Migrate plugin.

Differences between HashSet and HashMap in Java

1) First and most significant difference between HashMap and HashSet is that HashMap is an implementation of Map interface while HashSet is an implementation of Set interface, which means HashMap is a key value based data-structure and HashSet guarantees uniqueness by not allowing duplicates.In reality HashSet is a wrapper around HashMap in Java, if you look at the code of add(E e) method of HashSet.java you will see following code :

public boolean add(E e) 
{
    return map.put(e, PRESENT)==null;
}

where its putting Object into map as key and value is an final object PRESENT which is dummy.

2) Second difference between HashMap and HashSet is that , we use add() method to put elements into Set but we use put() method to insert key and value into HashMap in Java.

3) HashSet allows only one null key, but HashMap can allow one null key + multiple null values.

That's all on difference between HashSet and HashMap in Java. In summary HashSet and HashMap are two different type of Collection one being Set and other being Map.

I had to add parseInt() to tell v-for it was looking at a number.

<li v-for="n in parseInt(count)" :key="n">{{n}}</li>

git branch show current branch name only.

While git branch will show you all branches and highlight the current one with an asterisk, it can be too cumbersome when working with lots of branches.

To show only the branch you are currently on, use:

git rev-parse --abbrev-ref HEAD

I prefer to use the node.isConnected property (Visit MDN).

Note: This will return true if the element is appended to a ShadowRoot as well, which might not be everyone's desired behaviour.

Example:

const element = document.createElement('div');
console.log(element.isConnected); // Returns false
document.body.append(element);
console.log(element.isConnected); // Returns true

It's the year 2017.

I made some tests.

https://jsperf.com/fastest-way-to-iterate-through-an-array/

Looks like the while method is the fastest on Chrome.

Looks like the left decrement (--i) is much faster than the others (++i, i--, i++) on Firefox.

This approach is the fasted on average. But it iterates the array in reversed order.

let i = array.length;
while (--i >= 0) {
    doSomething(array[i]);
}

If the forward order is important, use this approach.

let ii = array.length;
let i = 0;
while (i < ii) {
    doSomething(array[i]);
    ++i;
}

Use positive lookahead assertions:

var regularExpression = /^(?=.*[0-9])(?=.*[!@#$%^&*])[a-zA-Z0-9!@#$%^&*]{6,16}$/;

Without it, your current regex only matches that you have 6 to 16 valid characters, it doesn't validate that it has at least a number, and at least a special character. That's what the lookahead above is for.

• (?=.*[0-9]) - Assert a string has at least one number;
• (?=.*[!@#$%^&*]) - Assert a string has at least one special character.

I tried the solution answered above:

apt-get remove python-pip python3-pip
wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py
python3 get-pip.py

When I tried

python get-pip.py 
python3 get-pip.py

I got this message

 Could not install packages due to an EnvironmentError:
[Errno 13] Permission denied: /usr/bin/pip3 Consider using the --user
 option or check the permissions.

I did the following and it works

python3 -m venv env
source ./env/bin/activate
Sudo apt-get update 
apt-get remove python-pip python3-pip
wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py
python3 get-pip.py
pip3 install pip
sudo easy_install pip
pip install --upgrade pip

If you declare a DateTime, then the default value is DateTime.MinValue, and hence you have to check it like this:

DateTime dat = new DateTime();

 if (dat==DateTime.MinValue)
 {
     //unassigned
 }

If the DateTime is nullable, well that's a different story:

 DateTime? dat = null;

 if (!dat.HasValue)
 {
     //unassigned
 }

Use this annotation

@RequestMapping(value = "/url", method = RequestMethod.GET, produces = {MediaType.APPLICATION_JSON})

I was looking for caching for my phonegap app storage and I found the answer of @TecHunter which is great but done using localCache.

I found and come to know that localStorage is another alternative to cache the data returned by ajax call. So, I created one demo using localStorage which will help others who may want to use localStorage instead of localCache for caching.

Ajax Call:

$.ajax({
    type: "POST",
    dataType: 'json',
    contentType: "application/json; charset=utf-8",
    url: url,
    data: '{"Id":"' + Id + '"}',
    cache: true, //It must "true" if you want to cache else "false"
    //async: false,
    success: function (data) {
        var resData = JSON.parse(data);
        var Info = resData.Info;
        if (Info) {
            customerName = Info.FirstName;
        }
    },
    error: function (xhr, textStatus, error) {
        alert("Error Happened!");
    }
});

To store data into localStorage:

$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
if (options.cache) {
    var success = originalOptions.success || $.noop,
        url = originalOptions.url;

    options.cache = false; //remove jQuery cache as we have our own localStorage
    options.beforeSend = function () {
        if (localStorage.getItem(url)) {
            success(localStorage.getItem(url));
            return false;
        }
        return true;
    };
    options.success = function (data, textStatus) {
        var responseData = JSON.stringify(data.responseJSON);
        localStorage.setItem(url, responseData);
        if ($.isFunction(success)) success(responseJSON); //call back to original ajax call
    };
}
});

If you want to remove localStorage, use following statement wherever you want:

localStorage.removeItem("Info");

Hope it helps others!

Based on gbinflames' answer, this is what worked for me:

Generate a simple mailchimp list sign up form , copy the action URL and method (post) to your custom form. Also rename your form field names to all capital ( name='EMAIL' as in original mailchimp code, EMAIL,FNAME,LNAME,... ), then use this:

      $form=$('#your-subscribe-form'); // use any lookup method at your convenience

      $.ajax({
      type: $form.attr('method'),
      url: $form.attr('action').replace('/post?', '/post-json?').concat('&c=?'),
      data: $form.serialize(),
      timeout: 5000, // Set timeout value, 5 seconds
      cache       : false,
      dataType    : 'jsonp',
      contentType: "application/json; charset=utf-8",
      error       : function(err) { // put user friendly connection error message  },
      success     : function(data) {
          if (data.result != "success") {
              // mailchimp returned error, check data.msg
          } else {
              // It worked, carry on...
          }
      }

To compare two lists with the order preserved use,

assertThat(actualList, contains("item1","item2"));

If you need a Win 10 UWP compatible variant:

using DomXmlDocument = Windows.Data.Xml.Dom.XmlDocument;

    public static class DocumentExtensions
    {
        public static XmlDocument ToXmlDocument(this XDocument xDocument)
        {
            var xmlDocument = new XmlDocument();
            using (var xmlReader = xDocument.CreateReader())
            {
                xmlDocument.Load(xmlReader);
            }
            return xmlDocument;
        }

        public static DomXmlDocument ToDomXmlDocument(this XDocument xDocument)
        {
            var xmlDocument = new DomXmlDocument();
            using (var xmlReader = xDocument.CreateReader())
            {
                xmlDocument.LoadXml(xmlReader.ReadOuterXml());
            }
            return xmlDocument;
        }

        public static XDocument ToXDocument(this XmlDocument xmlDocument)
        {
            using (var memStream = new MemoryStream())
            {
                using (var w = XmlWriter.Create(memStream))
                {
                    xmlDocument.WriteContentTo(w);
                }
                memStream.Seek(0, SeekOrigin.Begin);
                using (var r = XmlReader.Create(memStream))
                {
                    return XDocument.Load(r);
                }
            }
        }

        public static XDocument ToXDocument(this DomXmlDocument xmlDocument)
        {
            using (var memStream = new MemoryStream())
            {
                using (var w = XmlWriter.Create(memStream))
                {
                    w.WriteRaw(xmlDocument.GetXml());
                }
                memStream.Seek(0, SeekOrigin.Begin);
                using (var r = XmlReader.Create(memStream))
                {
                    return XDocument.Load(r);
                }
            }
        }
    }

You might want to look at the RouteLink() method.That one lets you specify everything (except the link text and route name) via a dictionary.

Security is one aspect you missed.

With Websockets the data has to go via a central webserver which typically sees all the traffic and can access it.

With WebRTC the data is end-to-end encrypted and does not pass through a server (except sometimes TURN servers are needed, but they have no access to the body of the messages they forward).

Depending on your application this may or may not matter.

If you are sending large amounts of data, the saving in cloud bandwidth costs due to webRTC's P2P architecture may be worth considering too.

This code will print a pyramid of dollars.

public static void main(String[] args) {

     for(int i=0;i<5;i++) {
         for(int j=0;j<5-i;j++) {
             System.out.print(" ");
         }
        for(int k=0;k<=i;k++) {
            System.out.print("$ ");
        }
        System.out.println();  
    }

}

OUPUT :

     $ 
    $ $ 
   $ $ $ 
  $ $ $ $ 
 $ $ $ $ $

So to make your expression work, changing && for -a will do the trick.

It is correct like this:

 if [ -f $VAR1 ] && [ -f $VAR2 ] && [ -f $VAR3 ]
 then  ....

or like

 if [[ -f $VAR1 && -f $VAR2 && -f $VAR3 ]]
 then  ....

or even

 if [ -f $VAR1 -a -f $VAR2 -a -f $VAR3 ]
 then  ....

You can find further details in this question bash : Multiple Unary operators in if statement and some references given there like What is the difference between test, [ and [[ ?.

I would recommend using Properties.Settings to store values like ConnectionStrings and so on inside of the class library. This is where all the connection strings are stores in by suggestion from visual studio when you try to add a table adapter for example. enter image description here

And then they will be accessible by using this code every where in the clas library

var cs=  Properties.Settings.Default.[<name of defined setting>];

This worked for me. adding two dots and slash.

body{
    background: url(../images/yourimage.png);
}

function printCrossword(printContainer) {
    var DocumentContainer = getElement(printContainer);
    var WindowObject = window.open('', "PrintWindow", "width=5,height=5,top=200,left=200,toolbars=no,scrollbars=no,status=no,resizable=no");
    WindowObject.document.writeln(DocumentContainer.innerHTML);
    WindowObject.document.close();
    WindowObject.focus();
    WindowObject.print();
    WindowObject.close();
}

Using the .not() method with selecting an entire element is also an option.

This way could be usefull if you want to do another action with that element directly.

$(".thisClass").not($("#thisId")[0].doAnotherAction()).doAction();

To use base_url() (shorthand), you have to load the URL Helper first

$this->load->helper('url');

Or you can autoload it by changing application/config/autoload.php

Or just use

$this->config->base_url();

Same applies to site_url().

Also I can see you are missing echo (though its not your current problem), use the code below to solve the problem

<link rel="stylesheet" href="<?php echo base_url(); ?>css/default.css" type="text/css" />

Well it's a very confusing kind of bug. There could be many reasons:

1. You are not mentioning the permissions in right place. Like right above application.
2. You are not using small letters.
3. In some case you also have to add Network state permission.
4. One which was my case there are some blank lines in manifest lines. Like there might be a blank line between permission tag and application line. Remove them and you are done. Hope it will help

I think this is what you want:

document.getElementById('tag-id').innerHTML = '<ol><li>html data</li></ol>';

Keep in mind that innerHTML is not accessible for all types of tags when using IE. (table elements for example)
