It's worth noting that if you want a currently-focused field to update the keyboard type immediately, there's one extra step:

// textField is set to a UIKeyboardType other than UIKeyboardTypeEmailAddress

[textField setKeyboardType:UIKeyboardTypeEmailAddress];
[textField reloadInputViews];

Without the call to reloadInputViews, the keyboard will not change until the selected field (the first responder) loses and regains focus.

A full list of the UIKeyboardType values can be found here, or:

typedef enum : NSInteger {
    UIKeyboardTypeDefault,
    UIKeyboardTypeASCIICapable,
    UIKeyboardTypeNumbersAndPunctuation,
    UIKeyboardTypeURL,
    UIKeyboardTypeNumberPad,
    UIKeyboardTypePhonePad,
    UIKeyboardTypeNamePhonePad,
    UIKeyboardTypeEmailAddress,
    UIKeyboardTypeDecimalPad,
    UIKeyboardTypeTwitter,
    UIKeyboardTypeWebSearch,
    UIKeyboardTypeAlphabet = UIKeyboardTypeASCIICapable
} UIKeyboardType;

The method by ZAFAR007 updated for Swift 5 in Xcode 10

override func viewDidLoad() {
    super.viewDidLoad()

    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name: UIResponder.keyboardWillShowNotification, object: nil)

}




@objc func keyboardWillShow(notification: NSNotification) {

    if let keyboardSize = (notification.userInfo?[UIResponder.keyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
        let keyboardHeight : Int = Int(keyboardSize.height)
        print("keyboardHeight",keyboardHeight)
    }

}

If you connect the DidEndOnExit event of the text field to an action (IBAction) in InterfaceBuilder, it will be messaged when the user dismisses the keyboard (with the return key) and the sender will be a reference to the UITextField that fired the event.

For example:

-(IBAction)userDoneEnteringText:(id)sender
{
    UITextField theField = (UITextField*)sender;
    // do whatever you want with this text field
}

Then, in InterfaceBuilder, link the DidEndOnExit event of the text field to this action on your controller (or whatever you're using to link events from the UI). Whenever the user enters text and dismisses the text field, the controller will be sent this message.

Swift 3 code

var activeField: UITextField?

override func viewDidLoad() {
    super.viewDidLoad()

    NotificationCenter.default.addObserver(self, selector: #selector(ProfileViewController.keyboardWillShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(ProfileViewController.keyboardWillHide), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}

func textFieldDidBeginEditing(_ textField: UITextField){
    activeField = textField
}

func textFieldDidEndEditing(_ textField: UITextField){
    activeField = nil
}

func keyboardWillShow(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
        if (self.activeField?.frame.origin.y)! >= keyboardSize.height {
            self.view.frame.origin.y = keyboardSize.height - (self.activeField?.frame.origin.y)!
        } else {
            self.view.frame.origin.y = 0
        }
    }
}

func keyboardWillHide(notification: NSNotification) {
    self.view.frame.origin.y = 0
}

If you want to disappear keyboard when writing on alert box textfileds

[[alertController.textFields objectAtIndex:1] resignFirstResponder];

One thing to consider is whether you ever want to use a UITextField on its own. I haven’t come across any well-designed iPhone apps that actually use UITextFields outside of UITableViewCells.

It will be some extra work, but I recommend you implement all data entry views a table views. Add a UITextView to your UITableViewCells.

  import UIKit

  class ItemViewController: UIViewController, UITextFieldDelegate {

  @IBOutlet weak var nameTextField: UITextField!

    override func viewDidLoad() {
           super.viewDidLoad()
           self.nameTextField.delegate = self
     }

    // Called when 'return' key pressed. return NO to ignore.

    func textFieldShouldReturn(textField: UITextField) -> Bool {

            textField.resignFirstResponder()
             return true
     }

 // Called when the user click on the view (outside the UITextField).

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?)    {
      self.view.endEditing(true)
  }
}

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy MM dd");
String text = date.toString(formatter);
LocalDate date = LocalDate.parse(text, formatter);

I believe this might help, you may need to use some sort of localdate variation instead of instant

I really wanted this (placeholders should look the same for text boxes as select boxes!) and straight CSS wasn't working in Chrome. Here is what I did:

First make sure your select tag has a .has-prompt class.

Then initialize this class somewhere in document.ready.

# Adds a class to select boxes that have prompt currently selected.
# Allows for placeholder-like styling.
# Looks for has-prompt class on select tag.
Mess.Views.SelectPromptStyler = Backbone.View.extend
  el: 'body'

  initialize: ->
    @$('select.has-prompt').trigger('change')

  events:
    'change select.has-prompt': 'changed'

  changed: (e) ->
    select = @$(e.currentTarget)
    if select.find('option').first().is(':selected')
      select.addClass('prompt-selected')
    else
      select.removeClass('prompt-selected')

Then in CSS:

select.prompt-selected {
  color: $placeholder-color;
}

This helped me when I had problems with the Features screen due to AppFabric and Windows Update errors.

The important difference between signed and unsigned ints is the interpretation of the last bit. The last bit in signed types represent the sign of the number, meaning: e.g:

0001 is 1 signed and unsigned 1001 is -1 signed and 9 unsigned

(I avoided the whole complement issue for clarity of explanation! This is not exactly how ints are represented in memory!)

You can imagine that it makes a difference to know if you compare with -1 or with +9. In many cases, programmers are just too lazy to declare counting ints as unsigned (bloating the for loop head f.i.) It is usually not an issue because with ints you have to count to 2^31 until your sign bit bites you. That's why it is only a warning. Because we are too lazy to write 'unsigned' instead of 'int'.

That is invalid syntax. You are mixing relational expressions with scalar operators (OR). Specifically you cannot combine expr IN (select ...) OR (select ...). You probably want expr IN (select ...) OR expr IN (select ...). Using union would also work: expr IN (select... UNION select...)

pluck(column_name)

This method is designed to perform select by a single column as direct SQL query Returns Array with values of the specified column name The values has same data type as column.

Examples:

Person.pluck(:id) # SELECT people.id FROM people
Person.uniq.pluck(:role) # SELECT DISTINCT role FROM people
Person.where(:confirmed => true).limit(5).pluck(:id)

see http://api.rubyonrails.org/classes/ActiveRecord/Calculations.html#method-i-pluck

Its introduced rails 3.2 onwards and accepts only single column. In rails 4, it accepts multiple columns

Try pasting this to .htaccess and it should work.

php_value post_max_size 2000M
php_value upload_max_filesize 2500M

php_value memory_limit 2500M

A bit verbose, but it's the standard way of parsing and formatting dates in Java:

DateFormat formatter = new SimpleDateFormat("HH:mm:ss");
try {
  Date dt = formatter.parse("08:19:12");
  Calendar cal = Calendar.getInstance();
  cal.setTime(dt);
  int hour = cal.get(Calendar.HOUR);
  int minute = cal.get(Calendar.MINUTE);
  int second = cal.get(Calendar.SECOND);
} catch (ParseException e) {
  // This can happen if you are trying to parse an invalid date, e.g., 25:19:12.
  // Here, you should log the error and decide what to do next
  e.printStackTrace();
}

I tried all above solution and fail, it just added a null file to the DB.

However, I was able to get it done by moving the image(fileName.jpg) file first in to below folder(in my case) C:\ProgramData\MySQL\MySQL Server 5.7\Uploads and then I executed below command and it works for me,

INSERT INTO xx_BLOB(ID,IMAGE) VALUES(1,LOAD_FILE('C:/ProgramData/MySQL/MySQL Server 5.7/Uploads/fileName.jpg'));

Hope this helps.

You have to use ':' colon instead of ';' semicolon.

As it stands now you try to execute the jar file which has not the execute bit set, hence the Permission denied.

And the variable must be CLASSPATH not classpath.

I have learned it is also possible to do this with the exec-maven-plugin if you're doing a "standalone" java app.

In my case I was trying to install Flask. I wanted to run pip install Flask command. But when I open command prompt it I goes to C:\Users[user]>. If you give here it will say pip is not recognized. I did below steps

On your desktop right click Computer and select Properties

Select Advanced Systems Settings

In popup which you see select Advanced tab and then click Environment Variables

In popup double click PATH and from popup copy variable value for variable name PATH and paste the variable value in notepad or so and look for an entry for Python.

In my case it was C:\Users\[user]\AppData\Local\Programs\Python\Python36-32

Now in my command prompt i moved to above location and gave pip install Flask

For me, in Ubuntu 18.04. I needed to chown inside ~/.config/composer/

E.g.

sudo chown -R $USER ~/.config/composer

Then global commands work.

TL;DR Check the network mode of your VirtualBox host - it should be bridged if you want the virtual machine (and the Docker container it's hosting) accessible on your local network.

It sounds like your confusion lies in which host to connect to in order to access your application via HTTP. You haven't really spelled out what your configuration is - I'm going to make some guesses, based on the fact that you've got "Windows" and "VirtualBox" in your tags.

I'm guessing that you have Docker running on some flavour of Linux running in VirtualBox on a Windows host. I'm going to label the IP addresses as follows:

D = the IP address of the Docker container

L = the IP address of the Linux host running in VirtualBox

W = the IP address of the Windows host

When you run your Go application on your Windows host, you can connect to it with http://W:8080/ from anywhere on your local network. This works because the Go application binds the port 8080 on the Windows machine and anybody who tries to access port 8080 at the IP address W will get connected.

And here's where it becomes more complicated:

VirtualBox, when it sets up a virtual machine (VM), can configure the network in one of several different modes. I don't remember what all the different options are, but the one you want is bridged. In this mode, VirtualBox connects the virtual machine to your local network as if it were a stand-alone machine on the network, just like any other machine that was plugged in to your network. In bridged mode, the virtual machine appears on your network like any other machine. Other modes set things up differently and the machine will not be visible on your network.

So, assuming you set up networking correctly for the Linux host (bridged), the Linux host will have an IP address on your local network (something like 192.168.0.x) and you will be able to access your Docker container at http://L:8080/.

If the Linux host is set to some mode other than bridged, you might be able to access from the Windows host, but this is going to depend on exactly what mode it's in.

EDIT - based on the comments below, it sounds very much like the situation I've described above is correct.

Let's back up a little: here's how Docker works on my computer (Ubuntu Linux).

Imagine I run the same command you have: docker run -p 8080:8080 dockertest. What this does is start a new container based on the dockertest image and forward (connect) port 8080 on the Linux host (my PC) to port 8080 on the container. Docker sets up it's own internal networking (with its own set of IP addresses) to allow the Docker daemon to communicate and to allow containers to communicate with one another. So basically what you're doing with that -p 8080:8080 is connecting Docker's internal networking with the "external" network - ie. the host's network adapter - on a particular port.

With me so far? OK, now let's take a step back and look at your system. Your machine is running Windows - Docker does not (currently) run on Windows, so the tool you're using has set up a Linux host in a VirtualBox virtual machine. When you do the docker run in your environment, exactly the same thing is happening - port 8080 on the Linux host is connected to port 8080 on the container. The big difference here is that your Windows host is not the Linux host on which the container is running, so there's another layer here and it's communication across this layer where you are running into problems.

What you need is one of two things:

1. to connect port 8080 on the VirtualBox VM to port 8080 on the Windows host, just like you connect the Docker container to the host port.

2. to connect the VirtualBox VM directly to your local network with the bridged network mode I described above.

If you go for the first option, you will be able to access the container at http://W:8080 where W is the IP address or hostname of the Windows host. If you opt for the second, you will be able to access the container at http://L:8080 where L is the IP address or hostname of the Linux VM.

So that's all the higher-level explanation - now you need to figure out how to change the configuration of the VirtualBox VM. And here's where I can't really help you - I don't know what tool you're using to do all this on your Windows machine and I'm not at all familiar with using Docker on Windows.

If you can get to the VirtualBox configuration window, you can make the changes described below. There is also a command line client that will modify VMs, but I'm not familiar with that.

For bridged mode (and this really is the simplest choice), shut down your VM, click the "Settings" button at the top, and change the network mode to bridged, then restart the VM and you're good to go. The VM should pick up an IP address on your local network via DHCP and should be visible to other computers on the network at that IP address.

I've been interested in the original question here and related ones.

For an answer, this week I did some experiments with XCOPY.

To help answer the original question, here I post the results of my experiments.

I did the experiments on Windows 7 64 bit Professional SP1 with the copy of XCOPY that came with the operating system.

For the experiments, I wrote some code in the scripting language Open Object Rexx and the editor macro language Kexx with the text editor KEdit.

XCOPY was called from the Rexx code. The Kexx code edited the screen output of XCOPY to focus on the crucial results.

The experiments all had to do with using XCOPY to copy one directory with several files and subdirectories.

The experiments consisted of 10 cases. Each case adjusted the arguments to XCOPY and called XCOPY once. All 10 cases were attempting to do the same copying operation.

Here are the main results:

(1) Of the 10 cases, only three did copying. The other 7 cases right away, just from processing the arguments to XCOPY, gave error messages, e.g.,

Invalid path

Access denied

with no files copied.

Of the three cases that did copying, they all did the same copying, that is, gave the same results.

(2) If want to copy a directory X and all the files and directories in directory X, in the hierarchical file system tree rooted at directory X, then apparently XCOPY -- and this appears to be much of the original question -- just will NOT do that.

One consequence is that if using XCOPY to copy directory X and its contents, then CAN copy the contents but CANNOT copy the directory X itself; thus, lose the time-date stamp on directory X, its archive bit, data on ownership, attributes, etc.

Of course if directory X is a subdirectory of directory Y, an XCOPY of Y will copy all of the contents of directory Y WITH directory X. So in this way can get a copy of directory X. However, the copy of directory X will have its time-date stamp of the time of the run of XCOPY and NOT the time-date stamp of the original directory X.

This change in time-date stamps can be awkward for a copy of a directory with a lot of downloaded Web pages: The HTML file of the Web page will have its original time-date stamp, but the corresponding subdirectory for files used by the HTML file will have the time-date stamp of the run of XCOPY. So, when sorting the copy on time date stamps, all the subdirectories, the HTML files and the corresponding subdirectories, e.g.,

x.htm

x_files

can appear far apart in the sort on time-date.

Hierarchical file systems go way back, IIRC to Multics at MIT in 1969, and since then lots of people have recognized the two cases, given a directory X, (i) copy directory X and all its contents and (ii) copy all the contents of X but not directory X itself. Well, if only from the experiments, XCOPY does only (ii).

So, the results of the 10 cases are below. For each case, in the results the first three lines have the first three arguments to XCOPY. So, the first line has the tree name of the directory to be copied, the 'source'; the second line has the tree name of the directory to get the copies, the 'destination', and the third line has the options for XCOPY. The remaining 1-2 lines have the results of the run of XCOPY.

One big point about the options is that options /X and /O result in result

Access denied

To see this, compare case 8 with the other cases that were the same, did not have /X and /O, but did copy.

These experiments have me better understand XCOPY and contribute an answer to the original question.

If u want a direct/ quick away, without assing to variables:

{
 urArray.map((prop, key) => {
     console.log(emp);
     return <Picker.Item label={emp.Name} value={emp.id} />;
 })
}

Depending on if your regex flavor supports it, I might use:

\b[A-Z]{2}\d{6}\b    # Ensure there are "word boundaries" on either side, or

(?<![A-Z])[A-Z]{2}\d{6}(?!\d) # Ensure there isn't a uppercase letter before
                              # and that there is not a digit after

if you want to just update node, there's a neat updater too

https://github.com/creationix/nvm

to use,

git clone git://github.com/creationix/nvm.git ~/.nvm

source ~/.nvm/nvm.sh

nvm install v0.4.1

You can use reorder:

qplot(reorder(factor(cyl),factor(cyl),length),data=mtcars,geom="bar")

Edit:

To have the tallest bar at the left, you have to use a bit of a kludge:

qplot(reorder(factor(cyl),factor(cyl),function(x) length(x)*-1),
   data=mtcars,geom="bar")

I would expect this to also have negative heights, but it doesn't, so it works!

The question has been answered, but for your future coding reference you might like to consider this.

In your HTML, add the name as an attribute to the button and remove the onclick reference.

<button id="button" data-name="Mathew" type="button">click</button>

In your JavaScript, grab the button using its ID, assign the function to the button's click event, and use the function to display the button's data-name attribute.

var button = document.getElementById('button');

button.onclick = myfunction;

function myfunction() {
  var name = this.getAttribute('data-name');
  alert(name);
}

You are using improper syntax. If you read the docs mysqli_query() you will find that it needs two parameter.

mixed mysqli_query ( mysqli $link , string $query [, int $resultmode = MYSQLI_STORE_RESULT ] )

mysql $link generally means, the resource object of the established mysqli connection to query the database.

So there are two ways of solving this problem

mysqli_query();

$myConnection= mysqli_connect("$db_host","$db_username","$db_pass", "mrmagicadam") or die ("could not connect to mysql"); 
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysqli_query($myConnection, $sqlCommand) or die(mysqli_error($myConnection));

Or, Using mysql_query() (This is now obselete)

$myConnection= mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql");
mysql_select_db("mrmagicadam") or die ("no database");        
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysql_query($sqlCommand) or die(mysql_error());

As pointed out in the comments, be aware of using die to just get the error. It might inadvertently give the viewer some sensitive information .

Don't update the primary key. It could cause a lot of problems for you keeping your data intact, if you have any other tables referencing it.

Ideally, if you want a unique field that is updateable, create a new field.

You can leverage the java_home helper binary on OS X for what you're looking for.

To list all versions of installed JDK:

$ /usr/libexec/java_home -V
Matching Java Virtual Machines (2):
    1.8.0_51, x86_64:   "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home
    1.7.0_79, x86_64:   "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home

To request the JAVA_HOME path of a specific JDK version, you can do:

$ /usr/libexec/java_home -v 1.7
/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home

$ /usr/libexec/java_home -v 1.8
/Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home

You could take advantage of the above commands in your script like this:

REQUESTED_JAVA_VERSION="1.7"
if POSSIBLE_JAVA_HOME="$(/usr/libexec/java_home -v $REQUESTED_JAVA_VERSION 2>/dev/null)"; then
    # Do this if you want to export JAVA_HOME
    export JAVA_HOME="$POSSIBLE_JAVA_HOME"
    echo "Java SDK is installed"
else
    echo "Did not find any installed JDK for version $REQUESTED_JAVA_VERSION"
fi

You might be able to do if-else and check for multiple different versions of java as well.

If you prefer XML output, java_home also has a -X option to output in XML.

$ /usr/libexec/java_home --help
Usage: java_home [options...]

In Rails 3.x

GroupUser.where(GroupUser.arel_table[:user_id].not_eq(me))

To shorten the length, you could store GroupUser.arel_table in a variable or if using inside the model GroupUser itself e.g., in a scope, you can use arel_table[:user_id] instead of GroupUser.arel_table[:user_id]

From the terminal (osx) I usually use

cordova plugin -l | xargs cordova plugins rm

Pipe, pipe everything!

To expand a bit: this command will loop through the results of cordova plugin -l and feed it to cordova plugins rm.

xargs is one of those commands that you wonder why you didn't know about before. See this tut.

You cannot directly see the query result using mysql_query its only fires the query in mysql nothing else.

For getting the result you have to add a lil things in your script like

require_once('db.php');  
 $sql="SELECT * FROM  modul1open WHERE idM1O>=(SELECT FLOOR( MAX( idM1O ) * RAND( ) )  FROM  modul1open) ORDER BY idM1O LIMIT 1";

 $result = mysql_query($sql);
 //echo [$result];
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
    print_r($row);
}

This will give you result;

If the above solution didn't work for you, you can use import { withRouter } from 'react-router-dom';

Using this you can export your child class as -

class MyApp extends Component{
    // your code
}

export default withRouter(MyApp);

And your class with Router -

// your code
<Router>
      ...
      <Route path="/myapp" component={MyApp} />
      // or if you are sending additional fields
      <Route path="/myapp" component={() =><MyApp process={...} />} />
<Router>

This is round robin DNS. This is a quite simple solution for load balancing. Usually DNS servers rotate/shuffle the DNS records for each incoming DNS request. Unfortunately it's not a real solution for fail-over. If one of the servers fail, some visitors will still be directed to this failed server.

Similar to some of the solutions posted, but in my case I did the status bar transparent and fix the position of the action bar with some negative margin

if (Build.VERSION.SDK_INT >= 21) {
    getWindow().setStatusBarColor(Color.TRANSPARENT);
    FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) toolbar.getLayoutParams();
    lp.setMargins(0, -getStatusBarHeight(), 0, 0);
}

And I used in the toolbar and the root view

android:fitsSystemWindows="true"

Nothing worked for me but following thing was awesome:

1) Open

httpd-xampp.conf

which is at

/opt/lampp/etc/extra/

2) Find <Directory "/opt/lampp/phpmyadmin">

3) Now just add Require all granted before

4) So the code will look like this
<Directory "/opt/lampp/phpmyadmin"> AllowOverride AuthConfig Limit Order allow,deny Allow from all Require all granted </Directory>

5) Now finally Restart the xampp with this command /opt/lampp/lampp restart

That's it and you are Done!

It also work with xampp. :)

Try this

index.html

<form action="form.php" method="post">
    Do you like stackoverflow?
    <input type="checkbox" name="like" value="Yes" />  
    <input type="submit" name="formSubmit" value="Submit" /> 
</form>

form.php

<html>
<head>
</head>
<body>

<?php
    if(isset($_POST['like']))
    {
        echo "<h1>You like Stackoverflow.<h1>";
    }
    else
    {
        echo "<h1>You don't like Stackoverflow.</h1>";
    }   
?>

</body>
</html>

Or this

<?php
    if(isset($_POST['like'])) && 
    $_POST['like'] == 'Yes') 
    {
        echo "You like Stackoverflow.";
    }
    else
    {
        echo "You don't like Stackoverflow.";
    }   
?>

There is also:

try:
    del mydict[key]
except KeyError:
    pass

This only does 1 lookup instead of 2. However, except clauses are expensive, so if you end up hitting the except clause frequently, this will probably be less efficient than what you already have.

git init

Add the files in your new local repository. This stages them for the first commit.

git add .

Adds the files in the local repository and stages them for commit. To unstage a file, use 'git reset HEAD YOUR-FILE'.

Commit the files that you've staged in your local repository.

git commit -m "First commit"
# Commits the tracked changes and prepares them to be pushed to a remote

repository. To remove this commit and modify the file, use 'git reset --soft HEAD~1' and commit and add the file again. Copy remote repository URL fieldAt the top of your GitHub repository's Quick Setup page, click to copy the remote repository URL.

In the Command prompt, add the URL for the remote repository where your local repository will be pushed.

git remote add origin remote repository URL
# Sets the new remote
git remote -v
# Verifies the new remote URL

Push the changes in your local repository to GitHub.

git push origin master
# Pushes the changes in your local repository up to the remote repository you 

specified as the origin

Scheme doesn't have algebraic data types or pattern matching but it's certainly a functional language. Annoying things about Python from a functional programming perspective:

1. Crippled Lambdas. Since Lambdas can only contain an expression, and you can't do everything as easily in an expression context, this means that the functions you can define "on the fly" are limited.

2. Ifs are statements, not expressions. This means, among other things, you can't have a lambda with an If inside it. (This is fixed by ternaries in Python 2.5, but it looks ugly.)

3. Guido threatens to remove map, filter, and reduce every once in a while

On the other hand, python has lexical closures, Lambdas, and list comprehensions (which are really a "functional" concept whether or not Guido admits it). I do plenty of "functional-style" programming in Python, but I'd hardly say it's ideal.

In the spirit of "just delete all those weird characters before the <?xml", here's my Java code, which works well with input via a BufferedReader:

    BufferedReader test = new BufferedReader(new InputStreamReader(fisTest));
    test.mark(4);
    while (true) {
        int earlyChar = test.read();
        System.out.println(earlyChar);
        if (earlyChar == 60) {
            test.reset();
            break;
        } else {
            test.mark(4);
        }
    }

FWIW, the bytes I was seeing are (in decimal): 239, 187, 191.

Your method's return value has to be a List<Project>.

Using select new you are creating an instance of an anonymous type, instead of a Project.

You can fix it, that increasing the amount of inotify watchers.

If you are not interested in the technical details and only want to get Listen to work:

• If you are running Debian, RedHat, or another similar Linux distribution, run the following in a terminal:

  $ echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

• If you are running ArchLinux, run the following command instead

  $ echo fs.inotify.max_user_watches=524288 | sudo tee /etc/sysctl.d/40-max-user-watches.conf && sudo sysctl --system

Then paste it in your terminal and press on enter to run it.

The Technical Details

Listen uses inotify by default on Linux to monitor directories for changes. It's not uncommon to encounter a system limit on the number of files you can monitor. For example, Ubuntu Lucid's (64bit) inotify limit is set to 8192.

You can get your current inotify file watch limit by executing:

$ cat /proc/sys/fs/inotify/max_user_watches

When this limit is not enough to monitor all files inside a directory, the limit must be increased for Listen to work properly.

You can set a new limit temporary with:

$ sudo sysctl fs.inotify.max_user_watches=524288
$ sudo sysctl -p

If you like to make your limit permanent, use:

$ echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf
$ sudo sysctl -p

You may also need to pay attention to the values of max_queued_events and max_user_instances if listen keeps on complaining.

I couldn't find any major points on JetBrains' website and even Google didn't help that much.

You should train your search-fu twice as harder.

FROM: http://www.jetbrains.com/phpstorm/

NOTE: PhpStorm includes all the functionality of WebStorm (HTML/CSS Editor, JavaScript Editor) and adds full-fledged support for PHP and Databases/SQL.

Their forum also has quite few answers for such question.

Basically: PhpStorm = WebStorm + PHP + Database support

WebStorm comes with certain (mainly) JavaScript oriented plugins bundled by default while they need to be installed manually in PhpStorm (if necessary).

At the same time: plugins that require PHP support would not be able to install in WebStorm (for obvious reasons).

P.S. Since WebStorm has different release cycle than PhpStorm, it can have new JS/CSS/HTML oriented features faster than PhpStorm (it's all about platform builds used).

For example: latest stable PhpStorm is v7.1.4 while WebStorm is already on v8.x. But, PhpStorm v8 will be released in approximately 1 month (accordingly to their road map), which means that stable version of PhpStorm will include some of the features that will only be available in WebStorm v9 (quite few months from now, lets say 2-3-5) -- if using/comparing stable versions ONLY.

UPDATE (2016-12-13): Since 2016.1 version PhpStorm and WebStorm use the same version/build numbers .. so there is no longer difference between the same versions: functionality present in WebStorm 2016.3 is the same as in PhpStorm 2016.3 (if the same plugins are installed, of course).

Everything that I know atm. is that PHPStorm doesn't support JS part like Webstorm

That's not correct (your wording). Missing "extra" technology in PhpStorm (for example: node, angularjs) does not mean that basic JavaScript support has missing functionality. Any "extras" can be easily installed (or deactivated, if not required).

UPDATE (2016-12-13): Here is the list of plugins that are bundled with WebStorm 2016.3 but require manual installation in PhpStorm 2016.3 (if you need them, of course):

• Cucumber.js
• Dart
• EditorConfig
• EJS
• Handelbars/Mustache
• Java Server Pages (JSP) Integration
• Karma
• LiveEdit
• Meteor
• PhoneGap/Cordova Plugin
• Polymer & Web Components
• Pug (ex-Jade)
• Spy-js
• Stylus support
• Yeoman

"Once upon a time there were three little pigs".Split(" ") | ForEach {
    "$_ is a token"
 }

The key is $_, which stands for the current variable in the pipeline.

About the code you found online:

% is an alias for ForEach-Object. Anything enclosed inside the brackets is run once for each object it receives. In this case, it's only running once, because you're sending it a single string.

$_.Split(" ") is taking the current variable and splitting it on spaces. The current variable will be whatever is currently being looped over by ForEach.

The approach I took reads the header information from the first row to determine the indexes of the columns of interest.

You mentioned in the question that you also want the values output to a string. I dynamically build a format string for the output from the FORMAT column list. Rows are appended to the values string separated by a new line char.

The output column order is determined by the order of the column names in the FORMAT list.

In my code below the case of the column name in the FORMAT list is important. In the question above you've got 'Pincode' in your FORMAT list, but 'PinCode' in your excel. This wouldn't work below, it would need to be 'PinCode'.

from xlrd import open_workbook
wb = open_workbook('sample.xls')

FORMAT = ['Arm_id', 'DSPName', 'PinCode']
values = ""

for s in wb.sheets():
    headerRow = s.row(0)
    columnIndex = [x for y in FORMAT for x in range(len(headerRow)) if y == firstRow[x].value]
    formatString = ("%s,"*len(columnIndex))[0:-1] + "\n"

    for row in range(1,s.nrows):
        currentRow = s.row(row)
        currentRowValues = [currentRow[x].value for x in columnIndex]
        values += formatString % tuple(currentRowValues)

print values

For the sample input you gave above this code outputs:

>>> 1.0,JaVAS,282001.0
2.0,JaVAS,282002.0
3.0,JaVAS,282003.0

And because I'm a python noob, props be to: this answer, this answer, this question, this question and this answer.

It is possible to use a handler to do this, even in MVC4. Here's an example from one i made earlier:

public class ImageHandler : IHttpHandler
{
    byte[] bytes;

    public void ProcessRequest(HttpContext context)
    {
        int param;
        if (int.TryParse(context.Request.QueryString["id"], out param))
        {
            using (var db = new MusicLibContext())
            {
                if (param == -1)
                {
                    bytes = File.ReadAllBytes(HttpContext.Current.Server.MapPath("~/Images/add.png"));

                    context.Response.ContentType = "image/png";
                }
                else
                {
                    var data = (from x in db.Images
                                where x.ImageID == (short)param
                                select x).FirstOrDefault();

                    bytes = data.ImageData;

                    context.Response.ContentType = "image/" + data.ImageFileType;
                }

                context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
                context.Response.BinaryWrite(bytes);
                context.Response.Flush();
                context.Response.End();
            }
        }
        else
        {
            //image not found
        }
    }

    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}

In the view, i added the ID of the photo to the query string of the handler.

For a time field, use:

import time    
time.strftime('%Y-%m-%d %H:%M:%S')

I think strftime also applies to datetime.

The .Elements operation returns a LIST of XElements - but what you really want is a SINGLE element. Add this:

XElement Contacts = (from xml2 in XMLDoc.Elements("Contacts").Elements("Node")
                    where xml2.Element("ID").Value == variable
                    select xml2).FirstOrDefault();

This way, you tell LINQ to give you the first (or NULL, if none are there) from that LIST of XElements you're selecting.

To Answer your first question, Jenkins variables are case sensitive. However, if you are writing a windows batch script, they are case insensitive, because Windows doesn't care about the case.

Since you are not very clear about your setup, let's make the assumption that you are using an ant build step to fire up your ant task. Have a look at the Jenkins documentation (same page that Adarsh gave you, but different chapter) for an example on how to make Jenkins variables available to your ant task.

EDIT:

Hence, I will need to access the environmental variable ${BUILD_NUMBER} to construct the URL.

Why don't you use $BUILD_URL then? Isn't it available in the extended email plugin?

You cau use

ul.nav {
    display: none;
}

This will by default close the navbar. Please let me know anybody finds this usefull

For one liner lovers Array.from()

// creates 8x8 array filed with "0"    
const arr2d = Array.from({ length: 8 }, () => Array.from({ length: 8 }, () => "0"))

Another one (from comment by dmitry_romanov) use Array().fill()

// creates 8x8 array filed with "0"    
const arr2d = Array(8).fill(0).map(() => Array(8).fill("0"))

Using ES6+ spread operator ("inspired" by InspiredJW answer :) )

// same as above just a little shorter
const arr2d = [...Array(8)].map(() => Array(8).fill("0"))

You can use

import re

s = re.search(r"\[.*?]", string)
if s:
    print(s.group(0))

Array.prototype.map() index:

One can access the index Array.prototype.map() via the second argument of the callback function. Here is an example:

const array = [1, 2, 3, 4];_x000D_
_x000D_
_x000D_
const map = array.map((x, index) => {_x000D_
  console.log(index);_x000D_
  return x + index;_x000D_
});_x000D_
_x000D_
console.log(map);

Other arguments of Array.prototype.map():

• The third argument of the callback function exposes the array on which map was called upon
• The second argument of Array.map() is a object which will be the this value for the callback function. Keep in mind that you have to use the regular function keyword in order to declare the callback since an arrow function doesn't have its own binding to the this keyword.

For example:

const array = [1, 2, 3, 4];_x000D_
_x000D_
const thisObj = {prop1: 1}_x000D_
_x000D_
_x000D_
const map = array.map( function (x, index, array) {_x000D_
  console.log(array);_x000D_
  console.log(this)_x000D_
}, thisObj);

This is a state-of-the-union answer as of Windows PowerShell v5.1 / PowerShell Core v6.2.0:

• Andrew Savinykh's ill-fated answer, despite being the accepted one, is, as of this writing, fundamentally flawed (I do hope it gets fixed - there's enough information in the comments - and in the edit history - to do so).

• Ansgar Wiecher's helpful answer works well, but requires direct use of the .NET Framework (and reads the entire file into memory, though that could be changed). Direct use of the .NET Framework is not a problem per se, but is harder to master for novices and hard to remember in general.

• A future version of PowerShell Core will have a
  Convert-TextFile cmdlet with a -LineEnding parameter to allow in-place updating of text files with a specific newline style, as being discussed on GitHub.

In PSv5+, PowerShell-native solutions are now possible, because Set-Content now supports the -NoNewline switch, which prevents undesired appending of a platform-native newline^[1] :

# Convert CRLFs to LFs only.
# Note:
#  * (...) around Get-Content ensures that $file is read *in full*
#    up front, so that it is possible to write back the transformed content
#    to the same file.
#  * + "`n" ensures that the file has a *trailing LF*, which Unix platforms
#     expect.
((Get-Content $file) -join "`n") + "`n" | Set-Content -NoNewline $file

The above relies on Get-Content's ability to read a text file that uses any combination of CR-only, CRLF, and LF-only newlines line by line.

Caveats:

• You need to specify the output encoding to match the input file's in order to recreate it with the same encoding. The command above does NOT specify an output encoding; to do so, use -Encoding; without -Encoding:

  • In Windows PowerShell, you'll get "ANSI" encoding, your system's single-byte, 8-bit legacy encoding, such as Windows-1252 on US-English systems.
  • In PowerShell Core, you'll get UTF-8 encoding without a BOM.

• The input file's content as well as its transformed copy must fit into memory as a whole, which can be problematic with large input files.

• There's a risk of file corruption, if the process of writing back to the input file gets interrupted.

^{[1] In fact, if there are multiple strings to write, -NoNewline also doesn't place a newline between them; in the case at hand, however, this is irrelevant, because only one string is written.}

You have too many redundant nested arrays inside your jSON data, but it is possible to retrieve the information. Though like others have said you might want to clean it up.

use each() wrap within another each() until the last array.

for result.data[0].stuff[0].onetype[0] in jQuery you could do the following:

`

$.each(data.result.data, function(index0, v) {
    $.each(v, function (index1, w) {
        $.each(w, function (index2, x) {
            alert(x.id);
        });
    });

});

`

You can also use it esay way

SELECT *
FROM   inventory
WHERE  YEARWEEK(`modify`, 1) = YEARWEEK(CURDATE(), 1)

You forgot to link your app name to your heroku. It's a very common mistake. if your app is not created, then use:

heroku create (optional app name)

else:

git add .
git commit -m "heroku commit"

heroku git:remote -a YOUR_APP_NAME

git push heroku master

Using String.split method will surely work as told in other answers here.

Also, StringTokenizer class can be used to to parse the String using / as the delimiter.

import java.util.StringTokenizer;
public class Test
{
    public static void main(String []args)
    {
        String s = "prefix/dir1/dir2/dir3/dir4/..";
        StringTokenizer tokenizer = new StringTokenizer(s, "/");
        String dir1 = tokenizer.nextToken();
        String dir2 = tokenizer.nextToken();
        System.out.println("Dir 1  : "+dir1);
        System.out.println("Dir 2 : " + dir2);
    }
}

Gives the output as :

Dir 1  : prefix
Dir 2 : dir1

Here you can find more about StringTokenizer.

With java8 now, you can use

Integer offset  = ZonedDateTime.now().getOffset().getTotalSeconds();

to get the current system time offset from UTC. Then you can convert it to any format you want. Found it useful for my case. Example : https://docs.oracle.com/javase/tutorial/datetime/iso/timezones.html

A functional approach:

a = [1,"A", 34, -123, "Hello", 12]
b = [0, 2, 5]

from operator import itemgetter

print(list(itemgetter(*b)(a)))
[1, 34, 12]

$dom->@loadHTML($html);

This is incorrect, use this instead:

I created .pfx file from .key and .pem files.

Like this openssl pkcs12 -inkey rootCA.key -in rootCA.pem -export -out rootCA.pfx

That's not the direct answer but still maybe it helps out someone else.

The defer attribute is only for external scripts (should only be used if the src attribute is present).

Step 1:

npm install jquery

Step 2:

touch loader.js 

Somewhere in your project folder

Step 3:

//loader.js
window.$ = window.jQuery = require('jquery')

Step 4:

Import the loader into your root file before you import the files which require jQuery

//App.js
import '<pathToYourLoader>/loader.js'

Step 5:

Now use jQuery anywhere in your code:

//SomeReact.js
class SomeClass extends React.Compontent {

...

handleClick = () => {
   $('.accor > .head').on('click', function(){
      $('.accor > .body').slideUp();
      $(this).next().slideDown();
   });
}

...

export default SomeClass

startDate = new Date(today.getTime() - 30*24*60*60*1000);

The .getTime() method returns a standard JS timestamp (milliseconds since Jan 1/1970) on which you can use regular math operations, which can be fed back to the Date object directly.

I don't think maven supports this. If you're on Unix, and don't want to leave your current directory, you could use a small shell script, a shell function, or just a sub-shell:

user@host ~/project$ (cd ~/some/location; mvn install)
[ ... mvn build ... ]
user@host ~/project$

As a bash function (which you could add to your ~/.bashrc):

function mvn-there() {
  DIR="$1"
  shift
  (cd $DIR; mvn "$@")     
} 

user@host ~/project$ mvn-there ~/some/location install)
[ ... mvn build ... ]
user@host ~/project$

I realize this doesn't answer the specific question, but may provide you with what you're after. I'm not familiar with the Windows shell, though you should be able to reach a similar solution there as well.

As other have said, TRUNCATE TABLE is far quicker, but it does have some restrictions (taken from here):

You cannot use TRUNCATE TABLE on tables that:

- Are referenced by a FOREIGN KEY constraint. (You can truncate a table that has a foreign key that references itself.)
- Participate in an indexed view.
- Are published by using transactional replication or merge replication.

For tables with one or more of these characteristics, use the DELETE statement instead.

The biggest drawback is that if the table you are trying to empty has foreign keys pointing to it, then the truncate call will fail.

Uninstall the make install software when make uninstall invalid.

• make install will create file '.installed.list'
• Choose to clean up the files described in .installed.list (need to be careful if you have multiple versions)
• Case: ruby2.4 switch to ruby2.3, thinking directly delete all ruby software, and then re-make install 2.3, see: Ruby # Installation Guide
• make install -> .installed.list
• see .installed.list file, delete all install files.

Code like "a => b" means, for an associative array (some languages, like Perl, if I remember correctly, call those "hash"), that 'a' is a key, and 'b' a value.

You might want to take a look at the documentations of, at least:

• foreach
• arrays

Here, you are having an array, called $user_list, and you will iterate over it, getting, for each line, the key of the line in $user, and the corresponding value in $pass.

For instance, this code:

$user_list = array(
    'user1' => 'password1',
    'user2' => 'password2',
);

foreach ($user_list as $user => $pass)
{
    var_dump("user = $user and password = $pass");
}

Will get you this output:

string 'user = user1 and password = password1' (length=37)
string 'user = user2 and password = password2' (length=37)

(I'm using var_dump to generate a nice output, that facilitates debuging; to get a normal output, you'd use echo)

"Equal or greater" is the other way arround: "greater or equals", which is written, in PHP, like this; ">="
The Same thing for most languages derived from C: C++, JAVA, PHP, ...

As a piece of advice: If you are just starting with PHP, you should definitely spend some time (maybe a couple of hours, maybe even half a day or even a whole day) going through some parts of the manual :-)
It'd help you much!

in pure js just use offsetLeft and offsetTop properties.
Example fiddle: http://jsfiddle.net/WKZ8P/

var elm = document.querySelector('span');_x000D_
console.log(elm.offsetLeft, elm.offsetTop);

p   { position:relative; left:10px; top:85px; border:1px solid blue; }_x000D_
span{ position:relative; left:30px; top:35px; border:1px solid red; }

<p>_x000D_
    <span>paragraph</span>_x000D_
</p>

Besides using an attribute to pass information from a servlet to a JSP page, one can also pass a parameter. That is done simply by redirecting to a URL that specifies the JSP page in question, and adding the normal parameter-passing-through-the-URL mechanism.

An example. The relevant part of the servlet code:

protected void doGet( HttpServletRequest request, HttpServletResponse response )
throws ServletException, IOException
{
    response.setContentType( "text/html" );
    // processing the request not shown...
    //
    // here we decide to send the value "bar" in parameter
    // "foo" to the JSP page example.jsp:
    response.sendRedirect( "example.jsp?foo=bar" );
}

And the relevant part of JSP page example.jsp:

<%
    String fooParameter = request.getParameter( "foo" );
    if ( fooParameter == null )
    {
%>
    <p>No parameter foo given to this page.</p>
<%
    }
    else
    {
%>
    <p>The value of parameter foo is <%= fooParameter.toString() %>.</p>
<%
    }
%>

You need to unicode each element of the list individually

[x.encode('utf-8') for x in tmp]

Do not include the '.exe' in your file path.

For example:

from selenium import webdriver

driver = webdriver.Chrome(executable_path='path/to/folder/chromedriver')

The easiest way is to use lubridate:

library(lubridate)
prods.all$Date2 <- mdy(prods.all$Date2)

This function automatically returns objects of class POSIXct and will work with either factors or characters.

"top" is usually available on Solaris.

If not then revert to "vmstat" which is available on most UNIX system.

It should look something like this (from an AIX box)

vmstat

System configuration: lcpu=4 mem=12288MB ent=2.00

kthr    memory              page              faults              cpu
----- ----------- ------------------------ ------------ -----------------------
 r  b   avm   fre  re  pi  po  fr   sr  cy  in   sy  cs us sy id wa    pc    ec
 2  1 1614644 585722   0   0   1  22  104   0 808 29047 2767 12  8 77  3  0.45  22.3

the colums "avm" and "fre" tell you the total memory and free memery.

a "man vmstat" should get you the gory details.

You can also force flush the buffer to a file programmatically with the flush() method.

with open('out.log', 'w+') as f:
    f.write('output is ')
    # some work
    s = 'OK.'
    f.write(s)
    f.write('\n')
    f.flush()
    # some other work
    f.write('done\n')
    f.flush()

I have found this useful when tailing an output file with tail -f.

Did you try

$(this).val('test');

instead of

$(this).attr('value', 'test');

val() is generally easier, since the attribute you need to change may be different on different DOM elements.

Anyone can define "token_type" as an OAuth 2.0 extension, but currently "bearer" token type is the most common one.

https://tools.ietf.org/html/rfc6750

Basically that's what Facebook is using. Their implementation is a bit behind from the latest spec though.

If you want to be more secure than Facebook (or as secure as OAuth 1.0 which has "signature"), you can use "mac" token type.

However, it will be hard way since the mac spec is still changing rapidly.

https://tools.ietf.org/html/draft-ietf-oauth-v2-http-mac-05

I shared two solutions depending on your needs:

<style type="text/css" ref="stylesheet">
  .border-inside-box {
    border: 1px solid black;
  }
  .border-inside-box-v1 {
    outline: 1px solid black; /* 'border-radius' not available */
  }
  .border-outside-box-v2 {
    box-shadow: 0 0 0 1px black; /* 'border-style' not available (dashed, solid, etc) */
  }
</style>

example: https://codepen.io/danieldd/pen/gObEYKj

Only this worked for me:

#container:hover .cube { background-color: yellow; }

Where .cube is CssClass of the #cube.

Tested in Firefox, Chrome and Edge.

If you found “HAX is not working and emulator runs in emulation mode” problem while running android SDK. This mean your computer CPU must be intel core and must support “Hardware Accelerated Execution Manager”. It means that you have configured the emulator in a way which is not supported by your operating system.

See this link solving the problem http://www.javaexperience.com/hax-is-not-working-and-emulator-runs-in-emulation-mode/#ixzz2p3inMj34

Update : -

The link is down at the moment so posting archieved link of the webpage - https://web.archive.org/web/20151024002104/http://www.javaexperience.com/hax-is-not-working-and-emulator-runs-in-emulation-mode/

If your CPU isn't intel, then you have to edit your AVD and choose "CPU/ABI" as "ARM". For more details, please visit the link above.

I tried to alter the table and set auto_increment to 1 but it did not work. I resolved to delete the column name I was incrementing, then create a new column with your preferred name and set that new column to increment from the onset.

The issue was with the dmp file itself. I had to re-export the file and the command works fine. Thank you @Justin Cave

Regarding the " I couldn't get the SSIS import / export to work as I got the error 'Failure inserting into the read-only column "id"'. This can be gotten around by specifying in the mapping screen that you do want to allow Identity elements to be inserted.

After that, everything worked fine using SQL Import/Export wizard to copy from Azure to local database.

I only had SQL Import/Export Wizard that comes with SQL Server 2008 R2 (worked fine), and Visual Studio 2012 Express to create local database.

Jefferson is right, you have to do it backwards.

Here's the c# equivalent:

for (var i == list.Items.Count - 1; i >= 0; i--)
{
    list.Items.RemoveAt(i);
}

Since you mentioned Task Manager, I'll guess you're using Windows. Assuming you're running your script within the editor, if you aren't opposed to quitting the editor at the same time as quitting the running program, the keyboard shortcut to end a process is:

Alt + F4

(By which I mean press the 'Alt' and 'F4' keys on your keyboard simultaneously.)

Alternatively, as mentioned in other answers,

Ctrl + C

should also work, but will not quit the editor.

If you are using Mac OS, you can try GitUp(1)

For those who want a dumb down answer like me

Something like how to steps as 1, 2, 3

Here it is what I did

First create the HTML markup

<div class="thumb" data-image-src="images/img.jpg"></div>

Then before your ending body tag, add this script

I included the ending body on the code below as an example

So becareful when you copy

<script>
var list = document.getElementsByClassName('thumb');

for (var i = 0; i < list.length; i++) {
  var src = list[i].getAttribute('data-image-src');
  list[i].style.backgroundImage="url('" + src + "')";
}
</script>

</body>

It is also possible to place the MySQL data directory in a tmpfs in thus speeding up the database write and read calls. It might not be the most efficient way to do this but sometimes you can't just change the storage engine.

Here is my fstab entry for my MySQL data directory

none            /opt/mysql/server-5.6/data  tmpfs   defaults,size=1000M,uid=999,gid=1000,mode=0700          0       0

You may also want to take a look at the innodb_flush_log_at_trx_commit=2 setting. Maybe this will speedup your MySQL sufficently.

innodb_flush_log_at_trx_commit changes the mysql disk flush behaviour. When set to 2 it will only flush the buffer every second. By default each insert will cause a flush and thus cause more IO load.

This is how the complete code looks like. Note the import of android.view.Window.

package com.hoshan.tarik.test;

import android.app.Activity;
import android.os.Bundle;
import android.view.Window;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_main);
    }
}

Edit your php.ini, find allow_url_fopen and set it to allow_url_fopen = 1

There are two main ways that you can do this. One of them is the standard CakePHP way, and the other is using a custom join.

It's worth pointing out that this advice is for CakePHP 2.x, not 3.x.

The CakePHP Way

You would create a relationship with your User model and Messages Model, and use the containable behavior:

class User extends AppModel {
    public $actsAs = array('Containable');
    public $hasMany = array('Message');
}

class Message extends AppModel {
    public $actsAs = array('Containable');
    public $belongsTo = array('User');
}

You need to change the messages.from column to be messages.user_id so that cake can automagically associate the records for you.

Then you can do this from the messages controller:

$this->Message->find('all', array(
    'contain' => array('User')
    'conditions' => array(
        'Message.to' => 4
    ),
    'order' => 'Message.datetime DESC'
));

The (other) CakePHP way

I recommend using the first method, because it will save you a lot of time and work. The first method also does the groundwork of setting up a relationship which can be used for any number of other find calls and conditions besides the one you need now. However, cakePHP does support a syntax for defining your own joins. It would be done like this, from the MessagesController:

$this->Message->find('all', array(
    'joins' => array(
        array(
            'table' => 'users',
            'alias' => 'UserJoin',
            'type' => 'INNER',
            'conditions' => array(
                'UserJoin.id = Message.from'
            )
        )
    ),
    'conditions' => array(
        'Message.to' => 4
    ),
    'fields' => array('UserJoin.*', 'Message.*'),
    'order' => 'Message.datetime DESC'
));

Note, I've left the field name messages.from the same as your current table in this example.

Using two relationships to the same model

Here is how you can do the first example using two relationships to the same model:

class User extends AppModel {
    public $actsAs = array('Containable');
    public $hasMany = array(
        'MessagesSent' => array(
            'className'  => 'Message',
            'foreignKey' => 'from'
         )
    );
    public $belongsTo = array(
        'MessagesReceived' => array(
            'className'  => 'Message',
            'foreignKey' => 'to'
         )
    );
}

class Message extends AppModel {
    public $actsAs = array('Containable');
    public $belongsTo = array(
        'UserFrom' => array(
            'className'  => 'User',
            'foreignKey' => 'from'
        )
    );
    public $hasMany = array(
        'UserTo' => array(
            'className'  => 'User',
            'foreignKey' => 'to'
        )
    );
}

Now you can do your find call like this:

$this->Message->find('all', array(
    'contain' => array('UserFrom')
    'conditions' => array(
        'Message.to' => 4
    ),
    'order' => 'Message.datetime DESC'
));

You should be able to transfer the Application to another Username. You would need all your old user information to transfer it. The application would remove it's self from old account to new account. Also you could put a limit on how many times you where allowed to transfer it. If you transfer it to the application could expire after a year and force to buy update.

Override method authenticationManagerBean in WebSecurityConfigurerAdapter to expose the AuthenticationManager built using configure(AuthenticationManagerBuilder) as a Spring bean:

For example:

   @Bean(name = BeanIds.AUTHENTICATION_MANAGER)
   @Override
   public AuthenticationManager authenticationManagerBean() throws Exception {
       return super.authenticationManagerBean();
   }

Do I have to add an encapsulating <div> or <span>?

I think you do. The only thing that comes to mind is padding, but for that you would have to know the image's dimensions beforehand.

While most queries which employ CROSS APPLY can be rewritten using an INNER JOIN, CROSS APPLY can yield better execution plan and better performance, since it can limit the set being joined yet before the join occurs.

Stolen from Here

"Equivalent" is the word here

While...

$('#selectlist').val();

...is equivalent to...

document.getElementById("selectlist").value

...it's worth noting that...

$('#selectlist')

...although 'equivalent' is not the same as...

document.getElementById("selectlist")

...as the former returns a jQuery object, not a DOM object.

To get the DOM object(s) from the jQuery one, use the following:

$('#selectlist').get(); //get all DOM objects in the jQuery collection
$('#selectlist').get(0); //get the DOM object in the jQuery collection at index 0
$('#selectlist')[0]; //get the DOM objects in the jQuery collection at index 0

I had a similar problem using Tomcat against Oracle. I DID have the context.xml in the META-INF directory, on the disc. This file was not showing in the eclipse project though. A simple hit on the F5 refresh and the context.xml file appeared and eclipse published it. Everything worked past that. Hope this helps someone.

Try hitting F5 in eclipse

ascii is a package on linux you could download. for example sudo apt-get install ascii ascii

Usage: ascii [-dxohv] [-t] [char-alias...]
-t = one-line output  -d = Decimal table  -o = octal table  -x = hex table
-h = This help screen -v = version information
Prints all aliases of an ASCII character. Args may be chars, C \-escapes,
English names, ^-escapes, ASCII mnemonics, or numerics in decimal/octal/hex.`

This code can help you with C/C++ escape codes like \x0A

In Ruby, the condition and the then part of an if expression must be separated by either an expression separator (i.e. ; or a newline) or the then keyword.

So, all of these would work:

if @item.rigged then 'Yes' else 'No' end

if @item.rigged; 'Yes' else 'No' end

if @item.rigged
  'Yes' else 'No' end

There is also a conditional operator in Ruby, but that is completely unnecessary. The conditional operator is needed in C, because it is an operator: in C, if is a statement and thus cannot return a value, so if you want to return a value, you need to use something which can return a value. And the only things in C that can return a value are functions and operators, and since it is impossible to make if a function in C, you need an operator.

In Ruby, however, if is an expression. In fact, everything is an expression in Ruby, so it already can return a value. There is no need for the conditional operator to even exist, let alone use it.

BTW: it is customary to name methods which are used to ask a question with a question mark at the end, like this:

@item.rigged?

This shows another problem with using the conditional operator in Ruby:

@item.rigged? ? 'Yes' : 'No'

It's simply hard to read with the multiple question marks that close to each other.

Converting AM/PM Time string to 24 Hours Format. Example 9:30 PM to 21:30

function get24HrsFrmAMPM(timeStr) {
    if (timeStr && timeStr.indexOf(' ') !== -1 && timeStr.indexOf(':') !== -1) {
        var hrs = 0;
        var tempAry = timeStr.split(' ');
        var hrsMinAry = tempAry[0].split(':');
        hrs = parseInt(hrsMinAry[0], 10);
        if ((tempAry[1] == 'AM' || tempAry[1] == 'am') && hrs == 12) {
            hrs = 0;
        } else if ((tempAry[1] == 'PM' || tempAry[1] == 'pm') && hrs != 12) {
            hrs += 12;
        }
        return ('0' + hrs).slice(-2) + ':' + ('0' + parseInt(hrsMinAry[1], 10)).slice(-2);
    } else {
        return null;
    }
}

How about something like this?

val newDF = df.filter($"B" === "").take(1) match {
  case Array() => df
  case _ => df.withColumn("D", $"B" === "")
}

Using take(1) should have a minimal hit

In the Script Editor:

do shell script "/full/path/to/your/script -with 'all desired args'"

Save as an application bundle.

As long as all you want to do is get the effect of the script, this will work fine. You won't see STDOUT or STDERR.

jQuery + CSS for img

With jQuery this is working for me :

$('img').error(function() {
    $(this).attr('src', '/no-img.png').addClass('no-img');
});

And I can use this picture everywhere on my website regardless of the size of it with the following CSS3 property :

img.no-img {
    object-fit: cover;
    object-position: 50% 50%;
}

TIP 1 : use a square image of at least 800 x 800 pixels.

TIP 2 : for use with portrait of people, use object-position: 20% 50%;

CSS only for background-img

For missing background images, I also added the following on each background-image declaration :

background-image: url('path-to-image.png'), url('no-img.png');

NOTE : not working for transparent images.

Apache server side

Another solution is to detect missing image with Apache before to send to browser and remplace it by the default no-img.png content.

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} /images/.*\.(gif|jpg|jpeg|png)$
RewriteRule .* /images/no-img.png [L,R=307]

The command yum that you launch was executed properly. It returns a non zero status which means that an error occured during the processing of the command. You probably want to add some argument to your yum command to fix that.

Your code could show this error this way:

import subprocess
try:
    subprocess.check_output("dir /f",shell=True,stderr=subprocess.STDOUT)
except subprocess.CalledProcessError as e:
    raise RuntimeError("command '{}' return with error (code {}): {}".format(e.cmd, e.returncode, e.output))

For nullable, use ? with all of the C# primitives, except for string.

The following page gives a list of the C# primitives: http://msdn.microsoft.com/en-us/library/aa711900(v=vs.71).aspx

right click on your console and terminate. or click on stop

Use the Activity Monitor. It's the last toolbar in the top bar. It will show you a list of "Recent Expensive Queries". You can double-click them to see the execution plan, etc.

A pointer to member function is different from a pointer to function. In order to use a member function through a pointer you need a pointer to it (obviously ) and an object to apply it to. So the appropriate version of function1 would be

void function1(void (aClass::*function)(int, int), aClass& a) {
    (a.*function)(1, 1);
}

and to call it:

aClass a; // note: no parentheses; with parentheses it's a function declaration
function1(&aClass::test, a);

As Luiggi mentioned you need to change your main to:

import java.util.Arrays;

public class trial1{

    public static void main(String[] args){
        int[] A = numbers();
        System.out.println(Arrays.toString(A)); //Might require import of util.Arrays
    }

    public static int[] numbers(){
        int[] A = {1,2,3};
        return A;
    }
}

you can use this func

 class func stringIsNilOrEmpty(aString: String) -> Bool { return (aString).isEmpty }

This is happening because the WC_Customer abstract doesn't hold hold address data (among other data) apart from within a session. This data is stored via the cart/checkout pages, but again—only in the session (as far as the WC_Customer class goes).

If you take a look at how the checkout page gets the customer data, you'll follow it to the WC_Checkout class method get_value, which pulls it directly out of user meta. You'd do well to follow the same pattern :-)

As indicated at Python Mock object with method called multiple times

A solution is to write my own side_effect

def my_side_effect(*args, **kwargs):
    if args[0] == 42:
        return "Called with 42"
    elif args[0] == 43:
        return "Called with 43"
    elif kwargs['foo'] == 7:
        return "Foo is seven"

mockobj.mockmethod.side_effect = my_side_effect

That does the trick

// start snippet
error: function(XMLHttpRequest, textStatus, errorThrown) {
        if (XMLHttpRequest.readyState == 4) {
            // HTTP error (can be checked by XMLHttpRequest.status and XMLHttpRequest.statusText)
        }
        else if (XMLHttpRequest.readyState == 0) {
            // Network error (i.e. connection refused, access denied due to CORS, etc.)
        }
        else {
            // something weird is happening
        }
    }
//end snippet

var params = [
    'height='+screen.height,
    'width='+screen.width,
    'fullscreen=yes' // only works in IE, but here for completeness
].join(',');
     // and any other options from
     // https://developer.mozilla.org/en/DOM/window.open

var popup = window.open('http://www.google.com', 'popup_window', params); 
popup.moveTo(0,0);

Please refrain from opening the popup unless the user really wants it, otherwise they will curse you and blacklist your site. ;-)

edit: Oops, as Joren Van Severen points out in a comment, this may not take into account taskbars and window decorations (in a possibly browser-dependent way). Be aware. It seems that ignoring height and width (only param is fullscreen=yes) seems to work on Chrome and perhaps Firefox too; the original 'fullscreen' functionality has been disabled in Firefox for being obnoxious, but has been replaced with maximization. This directly contradicts information on the same page of https://developer.mozilla.org/en/DOM/window.open which says that window-maximizing is impossible. This 'feature' may or may not be supported depending on the browser.

If I had to guess, you did this:

import datetime

at the top of your code. This means that you have to do this:

datetime.datetime.strptime(date, "%Y-%m-%d")

to access the strptime method. Or, you could change the import statement to this:

from datetime import datetime

and access it as you are.

The people who made the datetime module also named their class datetime:

#module  class    method
datetime.datetime.strptime(date, "%Y-%m-%d")

Try this out. it works well for me. Make sure that before send email u need to give the access for less secure app in your gmail account. So go to the following link and try out with this java code.
Activate gmail for less secure app

You need to import javax.mail.jar file and activation.jar file to your project.

This is the full code for send email in java

I just came up with a general solution, which should work on most websites. I tried this on Chrome only, but this method should work with any other browser, though, as Dev Tools are pretty much the same in them all.

Steps:

1. Open the browser's Dev Tools (usually F12, or Ctrl-Shift-I, or right-click and then Inspect in the popup menu) on the page with the video you are interested in.
2. Go to Network tab and then reload the page. The tab will get populated with a list of requests (may be up to a hundred of them or even more).
3. Search through the names of requests and find the request with .m3u8 extension. There may be many of them, but most likely the first you find is the one you are looking for. It may have any name, e.g. playlist.m3u8.
4. Open the request and under Headers subsection you will see request's full URL in Request URL field. Copy it.
5. Extract the video from m3u8. There are many ways to do it, I'll give you those I tried, but you can google more by "download video from m3u8".
   • Option 1. If you have VLC player installed, feed the URL to VLC using "Open Network Stream..." menu option. I'm not going to go into details on this part here, there are a number of comprehensive guides in many places, for example, here. If the page doesn't work, you can always google another one by "vlc download online video".
   • Option 2. If you are more into command line, use FFMPEG or your own script, as directed in this SuperUser question.

You can use JavaScript to do what you want:

if (document.addEventListener !== undefined) {
  // Not IE
  document.addEventListener('click', checkSelection, false);
} else {
  // IE
  document.attachEvent('onclick', checkSelection);
}

function checkSelection() {
    var sel = {};
    if (window.getSelection) {
        // Mozilla
        sel = window.getSelection();
    } else if (document.selection) {
        // IE
        sel = document.selection.createRange();
    }

    // Mozilla
    if (sel.rangeCount) {
        sel.removeAllRanges();
        return;
    }

    // IE
    if (sel.text > '') {
        document.selection.empty();
        return;
    }
}

Soap box: You really shouldn't be screwing with the client's user agent in this manner. If the client wants to select things on the document, then they should be able to select things on the document. It doesn't matter if you don't like the highlight color, because you aren't the one viewing the document.

May be this could help

I know many of the solutions mentioned above works, you can as well try flex.

But my image was rectangular and not fitting properly. so this is what i did.

.parentDivClass {
    position: relative;
    height: 100px;
    width: 100px;
    overflow: hidden;
    border-radius: 50%;
    margin: 20px;
    display: flex;
    justify-content: center;
}

and for the image inside, you can use,

child Img {
    display: block;
    margin: 0 auto;
    height: 100%;
    width: auto;
}

This is helpful when you are using bootstrap 4 classes.

The other answers here are useful but they don't cover how to access Pacific specifically - here you go:

public static DateTime GmtToPacific(DateTime dateTime)
{
    return TimeZoneInfo.ConvertTimeFromUtc(dateTime,
        TimeZoneInfo.FindSystemTimeZoneById("Pacific Standard Time"));
}

Oddly enough, although "Pacific Standard Time" normally means something different from "Pacific Daylight Time," in this case it refers to Pacific time in general. In fact, if you use FindSystemTimeZoneById to fetch it, one of the properties available is a bool telling you whether that timezone is currently in daylight savings or not.

You can see more generalized examples of this in a library I ended up throwing together to deal with DateTimes I need in different TimeZones based on where the user is asking from, etc:

https://github.com/b9chris/TimeZoneInfoLib.Net

This won't work outside of Windows (for example Mono on Linux) since the list of times comes from the Windows Registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones\

Underneath that you'll find keys (folder icons in Registry Editor); the names of those keys are what you pass to FindSystemTimeZoneById. On Linux you have to use a separate Linux-standard set of timezone definitions, which I've not adequately explored.

You can use the redirect URL to controller:

Class Ctrlr1 extends CI_Controller{
public void my_fct1(){
redirect('Ctrlr2 /my_fct2', 'refresh');
}
}


Class Ctrlr2 extends CI_Controller{
public void my_fct2(){
$this->load->view('view1');
}
}

I needed something along the lines of a simple string reduction function recently. Basically, the code looked something like this (C/C++ code ahead):

size_t ReduceString(char *Dest, size_t DestSize, const char *Src, size_t SrcSize, bool Normalize)
{
    size_t x, x2 = 0, z = 0;

    memset(Dest, 0, DestSize);

    for (x = 0; x < SrcSize; x++)
    {
        Dest[x2] = (char)(((unsigned int)(unsigned char)Dest[x2]) * 37 + ((unsigned int)(unsigned char)Src[x]));
        x2++;

        if (x2 == DestSize - 1)
        {
            x2 = 0;
            z++;
        }
    }

    // Normalize the alphabet if it looped.
    if (z && Normalize)
    {
        unsigned char TempChr;
        y = (z > 1 ? DestSize - 1 : x2);
        for (x = 1; x < y; x++)
        {
            TempChr = ((unsigned char)Dest[x]) & 0x3F;

            if (TempChr < 10)  TempChr += '0';
            else if (TempChr < 36)  TempChr = TempChr - 10 + 'A';
            else if (TempChr < 62)  TempChr = TempChr - 36 + 'a';
            else if (TempChr == 62)  TempChr = '_';
            else  TempChr = '-';

            Dest[x] = (char)TempChr;
        }
    }

    return (SrcSize < DestSize ? SrcSize : DestSize);
}

It probably has more collisions than might be desired but it isn't intended for use as a cryptographic hash function. You might try various multipliers (i.e. change the 37 to another prime number) if you get too many collisions. One of the interesting features of this snippet is that when Src is shorter than Dest, Dest ends up with the input string as-is (0 * 37 + value = value). If you want something "readable" at the end of the process, Normalize will adjust the transformed bytes at the cost of increasing collisions.

The default port of SQL server is 1433.

The following answer is probably the most efficient but has the caveat of only being suitable for 1 to 1 mappings of arguments. This uses the fastest way of concatenating strings (similar to a stringbuilder: array of strings, joined). This is my own code. Probably needs a better separator though.

String.format = function(str, args)
{
    var t = str.split('~');
    var sb = [t[0]];
    for(var i = 0; i < args.length; i++){
        sb.push(args[i]);
        sb.push(t[i+1]);
    }
    return sb.join("");
}

Use it like:

alert(String.format("<a href='~'>~</a>", ["one", "two"]));

The <Leader> key is mapped to \ by default. So if you have a map of <Leader>t, you can execute it by default with \+t. For more detail or re-assigning it using the mapleader variable, see

:help leader

To define a mapping which uses the "mapleader" variable, the special string
"<Leader>" can be used.  It is replaced with the string value of "mapleader".
If "mapleader" is not set or empty, a backslash is used instead.  
Example:
    :map <Leader>A  oanother line <Esc>
Works like:
    :map \A  oanother line <Esc>
But after:
    :let mapleader = ","
It works like:
    :map ,A  oanother line <Esc>

Note that the value of "mapleader" is used at the moment the mapping is
defined.  Changing "mapleader" after that has no effect for already defined
mappings.

The pythonic way is to use enumerate:

for idx,item in enumerate(list):

For SQL Server:

ALTER TABLE TableName
    DROP COLUMN Column1, Column2;

The syntax is

DROP { [ CONSTRAINT ] constraint_name | COLUMN column } [ ,...n ] 

For MySQL:

ALTER TABLE TableName
    DROP COLUMN Column1,
    DROP COLUMN Column2;

or like this¹:

ALTER TABLE TableName
    DROP Column1,
    DROP Column2;

¹ The word COLUMN is optional and can be omitted, except for RENAME COLUMN (to distinguish a column-renaming operation from the RENAME table-renaming operation). More info here.

Your best bet is to use

table.YourClass tr:hover td {
background-color: #FEFEFE;
}

Rows aren't fully support for background color but cells are, using the combination of :hover and the child element will yield the results you need.

When you export you use the compatibility system set to MYSQL40. Worked for me.

FOUND THE SOLUTION: I added an action listener before uploadingDialog.show() like this:

    uploadingDialog.setOnCancelListener(new DialogInterface.OnCancelListener(){
          public void onCancel(DialogInterface dialog) {
              myTask.cancel(true);
              //finish();
          }
    });

That way when I press the back button, the above OnCancelListener cancels both dialog and task. Also you can add finish() if you want to finish the whole activity on back pressed. Remember to declare your async task as a variable like this:

    MyAsyncTask myTask=null;

and execute your async task like this:

    myTask = new MyAsyncTask();
    myTask.execute();

If the value stored in PropertyLoader.RET_SECONDARY_V_ARRAY is not "V_ARRAY", then you are using different types; even if they are declared identically (e.g. both are table of number) this will not work.

You're hitting this data type compatibility restriction:

You can assign a collection to a collection variable only if they have the same data type. Having the same element type is not enough.

You're trying to call the procedure with a parameter that is a different type to the one it's expecting, which is what the error message is telling you.

You need to make the second element a 1-tuple, eg:

a = ('2',)
b = 'z'
new = a + (b,)

You get a nice header output with the following command:

 curl -L -v -s -o /dev/null google.de

• -L, --location follow redirects
• -v, --verbose more output, indicates the direction
• -s, --silent don't show a progress bar
• -o, --output /dev/null don't show received body

Or the shorter version:

 curl -Lvso /dev/null google.de

Results in:

As you can see curl outputs both the outgoing and the incoming headers and skips the bodydata althought telling you how big the body is.

Additionally for every line the direction is indicated so that it is easy to read. I found it particular useful to trace down long chains of redirects.

I have been looking into the same problem! I think your problem is related to where you identify the variable that you use to populate the ArrayList that you return. If you define it inside the loop, then it will always reference the last row in the table in the database. In order to avoid this, you have to identify it outside the loop:

String name;
if (cursor.moveToFirst()) {

        while (cursor.isAfterLast() == false) {
            name = cursor.getString(cursor
                    .getColumnIndex(countyname));

            list.add(name);
            cursor.moveToNext();
        }
}

Your observation is correct. This behavior is happening due to the reuse of cells. But you dont have to do any thing with the prepareForReuse. Instead do your check in cellForItem and set the properties accordingly. Some thing like..

 - (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"cvCell" forIndexPath:indexPath];


if (cell.selected) {
     cell.backgroundColor = [UIColor blueColor]; // highlight selection 
}
else
{
     cell.backgroundColor = [UIColor redColor]; // Default color
}
return cell;
}

-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath  {

    UICollectionViewCell *datasetCell =[collectionView cellForItemAtIndexPath:indexPath];
    datasetCell.backgroundColor = [UIColor blueColor]; // highlight selection
 }  

 -(void)collectionView:(UICollectionView *)collectionView didDeselectItemAtIndexPath:(NSIndexPath *)indexPath {

UICollectionViewCell *datasetCell =[collectionView cellForItemAtIndexPath:indexPath]; 
datasetCell.backgroundColor = [UIColor redColor]; // Default color
}

1. Everything is encoded by default!!! This is pretty huge.

2. Declarative helpers can be compiled so you don't need to do anything special to share them. I think they will replace .ascx controls to some extent. You have to jump through some hoops to use an .ascx control in another project.

3. You can make a section required which is nice.

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

it will works

DELETE FROM on_search 
WHERE search_date < UNIX_TIMESTAMP(DATE_SUB(NOW(), INTERVAL 180 DAY))

SciPy has the function scipy.special.factorial (formerly scipy.misc.factorial)

>>> import math
>>> import scipy.special
>>> math.factorial(6)
720
>>> scipy.special.factorial(6)
array(720.0)

Apart from very good responses here, you could try this as well if you want to use your sub query as is.

Approach:

1) Select the desired column (Only 1) from your sub query

2) Use where to map the column name

Code:

 SELECT count(distinct dNum)
 FROM myDB.dbo.AQ
 WHERE A_ID in 
   (
    SELECT A_ID 
    FROM (SELECT DISTINCT TOP (0.1) PERCENT A_ID, COUNT(DISTINCT dNum) AS ud 
          FROM         myDB.dbo.AQ
          WHERE     M > 1 and B = 0 
          GROUP BY A_ID ORDER BY ud DESC
         ) a 
   )

You can use

#pragma GCC push_options
#pragma GCC optimize ("O0")

your code

#pragma GCC pop_options

to disable optimizations since GCC 4.4.

See the GCC documentation if you need more details.

you can do this by using just one line code..

I would like to add an example of prototypical inheritance with javascript to @Scott Driscoll answer. We'll be using classical inheritance pattern with Object.create() which is a part of EcmaScript 5 specification.

First we create "Parent" object function

function Parent(){

}

Then add a prototype to "Parent" object function

 Parent.prototype = {
 primitive : 1,
 object : {
    one : 1
   }
}

Create "Child" object function

function Child(){

}

Assign child prototype (Make child prototype inherit from parent prototype)

Child.prototype = Object.create(Parent.prototype);

Assign proper "Child" prototype constructor

Child.prototype.constructor = Child;

Add method "changeProps" to a child prototype, which will rewrite "primitive" property value in Child object and change "object.one" value both in Child and Parent objects

Child.prototype.changeProps = function(){
    this.primitive = 2;
    this.object.one = 2;
};

Initiate Parent (dad) and Child (son) objects.

var dad = new Parent();
var son = new Child();

Call Child (son) changeProps method

son.changeProps();

Check the results.

Parent primitive property did not change

console.log(dad.primitive); /* 1 */

Child primitive property changed (rewritten)

console.log(son.primitive); /* 2 */

Parent and Child object.one properties changed

console.log(dad.object.one); /* 2 */
console.log(son.object.one); /* 2 */

Working example here http://jsbin.com/xexurukiso/1/edit/

More info on Object.create here https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Object/create

In my case, if I remove the the contentType, I get the Internal Server Error.

This is what I got working after multiple attempts:

var request =  $.ajax({
    type: 'POST',
    url: '/ControllerName/ActionName' ,
    contentType: 'application/json; charset=utf-8',
    data: JSON.stringify({ projId: 1, userId:1 }), //hard-coded value used for simplicity
    dataType: 'json'
});

request.done(function(msg) {
    alert(msg);
});

request.fail(function (jqXHR, textStatus, errorThrown) {
    alert("Request failed: " + jqXHR.responseStart +"-" + textStatus + "-" + errorThrown);
});

And this is the controller code:

public JsonResult ActionName(int projId, int userId)
{
    var obj = new ClassName();

    var result = obj.MethodName(projId, userId); // variable used for readability
    return Json(result, JsonRequestBehavior.AllowGet);
}

Please note, the case of ASP.NET is little different, we have to apply JSON.stringify() to the data as mentioned in the update of this answer.

I had issues getting the above code to work within cookie.js. The following code managed to create the correct timestamp for the cookie expiration in my instance.

var inFifteenMinutes = new Date(new Date().getTime() + 15 * 60 * 1000);

This was from the FAQs for Cookie.js

Form.Close() is use to close an instance of a Form with in .NET application it does not kill the entire application. Application.exit() kills your application.

Yes, that is safe and recommended.

The only caveat from the page you referred is that you can't be modifying configuration of the mapper once it is shared; but you are not changing configuration so that is fine. If you did need to change configuration, you would do that from the static block and it would be fine as well.

EDIT: (2013/10)

With 2.0 and above, above can be augmented by noting that there is an even better way: use ObjectWriter and ObjectReader objects, which can be constructed by ObjectMapper. They are fully immutable, thread-safe, meaning that it is not even theoretically possible to cause thread-safety issues (which can occur with ObjectMapper if code tries to re-configure instance).

Super Thanks to user somedrew for their post here: https://bbs.archlinux.org/viewtopic.php?id=55485 on 2008-09-20 02:09:48

Looking in /sys/class/net should be one way

Here's my script to test for a network connection other than the loop back. I use the below in another script that I have for periodically testing if my website is accessible. If it's NOT accessible a popup window alerts me to a problem.

The script below prevents me from receiving popup messages every five minutes whenever my laptop is not connected to the network.

#!/usr/bin/bash

# Test for network conection
for interface in $(ls /sys/class/net/ | grep -v lo);
do
  if [[ $(cat /sys/class/net/$interface/carrier) = 1 ]]; then OnLine=1; fi
done
if ! [ $OnLine ]; then echo "Not Online" > /dev/stderr; exit; fi

Note for those new to bash: The final 'if' statement tests if NOT [!] online and exits if this is the case. See man bash and search for "Expressions may be combined" for more details.

P.S. I feel ping is not the best thing to use here because it aims to test a connection to a particular host NOT test if there is a connection to a network of any sort.

P.P.S. The Above works on Ubuntu 12.04 The /sys may not exist on some other distros. See below:

Modern Linux distributions include a /sys directory as a virtual filesystem (sysfs, comparable to /proc, which is a procfs), which stores and allows modification of the devices connected to the system, whereas many traditional UNIX and Unix-like operating systems use /sys as a symbolic link to the kernel source tree.[citation needed]

From Wikipedia https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard

One alternative would be to use the NULLIF operator other than <> or != which returns NULL if the two arguments are equal NULLIF in Microsoft Docs. So I believe WHERE clause can be modified for <> and != as follows:

NULLIF(arg1, arg2) IS NOT NULL

As I found that, using <> and != doesn't work for date in some cases. Hence using the above expression does the needful.

You should use the facade rather than Illuminate\Http\Request. Import it at the top:

use Request;

And make sure it doesn't conflict with the other class.

Edit: This answer was written a few years ago. I now favour the approach suggested by shuvrow below.

zeusstl is right. it works for me too.

   <select class="form-control select2" id="myselect">
                      <option disabled="disabled" selected></option>
                      <option>Male</option>
                      <option>Female</option>
                    </select>

   $.getJSON("mysite/json1.php", function(json){
        $('#myselect').empty();
        $('#myselect').append($('<option>').text("Select"));
        $.each(json, function(i, obj){

  $('#myselect').append($('<option>').text(obj.text).attr('value', obj.val));
        });
  });

How you generate the unique_ids is a useful question - but you seem to be making a counter productive assumption about when you generate them!

My point is that you do not need to generate these unique id's at the time of creating your rows, because they are essentially independent of the data being inserted.

What I do is pre-generate unique id's for future use, that way I can take my own sweet time and absolutely guarantee they are unique, and there's no processing to be done at the time of the insert.

For example I have an orders table with order_id in it. This id is generated on the fly when the user enters the order, incrementally 1,2,3 etc forever. The user does not need to see this internal id.

Then I have another table - unique_ids with (order_id, unique_id). I have a routine that runs every night which pre-loads this table with enough unique_id rows to more than cover the orders that might be inserted in the next 24 hours. (If I ever get 10000 orders in one day I'll have a problem - but that would be a good problem to have!)

This approach guarantees uniqueness and takes any processing load away from the insert transaction and into the batch routine, where it does not affect the user.

Below is another way by which we can JSON data with JSON.stringify() function

var Utils = {};
Utils.MyClass1 = function (id, member) {
    this.id = id;
    this.member = member;
}
var myobject = { MyClass1: new Utils.MyClass1("5678999", "text") };
alert(JSON.stringify(myobject));

in my case, i cannot clone github due to user is wrong.

go to ~/.gitconfig then try to remove this line of code (just delete it then save file).

[user]
    name = youruser
    email = [email protected]

or try to use one liner in your cmd or terminal : git config --global --remove-section user

and try to do git clone again. hope it'll fix your day. ><

I would like to extend nice answer of Jerome Dalbert. I found very easy to write your own annotation validators in JSR-303 way. You are not limited to have "one field" validation. You can create your own annotation on type level and have complex validation (see examples below). I prefer this way because I don't need mix different types of validation (Spring and JSR-303) like Jerome do. Also this validators are "Spring aware" so you can use @Inject/@Autowire out of box.

Example of custom object validation:

@Target({ TYPE, ANNOTATION_TYPE })
@Retention(RUNTIME)
@Constraint(validatedBy = { YourCustomObjectValidator.class })
public @interface YourCustomObjectValid {

    String message() default "{YourCustomObjectValid.message}";

    Class<?>[] groups() default {};

    Class<? extends Payload>[] payload() default {};
}

public class YourCustomObjectValidator implements ConstraintValidator<YourCustomObjectValid, YourCustomObject> {

    @Override
    public void initialize(YourCustomObjectValid constraintAnnotation) { }

    @Override
    public boolean isValid(YourCustomObject value, ConstraintValidatorContext context) {

        // Validate your complex logic 

        // Mark field with error
        ConstraintViolationBuilder cvb = context.buildConstraintViolationWithTemplate(context.getDefaultConstraintMessageTemplate());
        cvb.addNode(someField).addConstraintViolation();

        return true;
    }
}

@YourCustomObjectValid
public YourCustomObject {
}

Example of generic fields equality:

In Anon's answer:
"If you need something from super's __init__ to be done in addition to what is being done in the current class's __init__ , you must call it yourself, since that will not happen automatically"

It's incredible: he is wording exactly the contrary of the principle of inheritance.

It is not that "something from super's __init__ (...) will not happen automatically" , it is that it WOULD happen automatically, but it doesn't happen because the base-class' __init__ is overriden by the definition of the derived-clas __init__

So then, WHY defining a derived_class' __init__ , since it overrides what is aimed at when someone resorts to inheritance ??

It's because one needs to define something that is NOT done in the base-class' __init__ , and the only possibility to obtain that is to put its execution in a derived-class' __init__ function.
In other words, one needs something in base-class' __init__ in addition to what would be automatically done in the base-classe' __init__ if this latter wasn't overriden.
NOT the contrary.

Then, the problem is that the desired instructions present in the base-class' __init__ are no more activated at the moment of instantiation. In order to offset this inactivation, something special is required: calling explicitly the base-class' __init__ , in order to KEEP , NOT TO ADD, the initialization performed by the base-class' __init__ . That's exactly what is said in the official doc:

An overriding method in a derived class may in fact want to extend rather than simply replace the base class method of the same name. There is a simple way to call the base class method directly: just call BaseClassName.methodname(self, arguments).
http://docs.python.org/tutorial/classes.html#inheritance

That's all the story:

• when the aim is to KEEP the initialization performed by the base-class, that is pure inheritance, nothing special is needed, one must just avoid to define an __init__ function in the derived class

• when the aim is to REPLACE the initialization performed by the base-class, __init__ must be defined in the derived-class

• when the aim is to ADD processes to the initialization performed by the base-class, a derived-class' __init__ must be defined , comprising an explicit call to the base-class __init__

What I feel astonishing in the post of Anon is not only that he expresses the contrary of the inheritance theory, but that there have been 5 guys passing by that upvoted without turning a hair, and moreover there have been nobody to react in 2 years in a thread whose interesting subject must be read relatively often.

There can be no two Lancher AFAIK. Logcat is a usefull tool to debug and check application/machine status in the behind. it will be automatic while switching from one activity to another activity.

Concatenate with & operator

Dim str as String  'no need to create a string instance
str = "Hello " & "World"

You can concate with the + operator as well but you can get yourself into trouble when trying to concatenate numbers.

Concatenate with String.Concat()

str = String.Concat("Hello ", "World")

Useful when concatenating array of strings

StringBuilder.Append()

When concatenating large amounts of strings use StringBuilder, it will result in much better performance.

    Dim sb as new System.Text.StringBuilder()
    str = sb.Append("Hello").Append(" ").Append("World").ToString()

Strings in .NET are immutable, resulting in a new String object being instantiated for every concatenation as well a garbage collection thereof.

Magic commands such as

%matplotlib qt  

work in the iPython console and Notebook, but do not work within a script.

In that case, after importing:

from IPython import get_ipython

use:

get_ipython().run_line_magic('matplotlib', 'inline')

for inline plotting of the following code, and

get_ipython().run_line_magic('matplotlib', 'qt')

for plotting in an external window.

Edit: solution above does not always work, depending on your OS/Spyder version Anaconda issue on GitHub. Setting the Graphics Backend to Automatic (as indicated in another answer: Tools >> Preferences >> IPython console >> Graphics --> Automatic) solves the problem for me.

Then, after a Console restart, one can switch between Inline and External plot windows using the get_ipython() command, without having to restart the console.

Recent versions of bash don't require call to the external program date:

printf -v timestamp '%(%T)T'

%(...)T uses the corresponding argument as a UNIX timestamp, and formats it according to the strftime-style format between the parentheses. An argument of -1 corresponds to the current time, and when no ambiguity would occur can be omitted.

Another solution to the issue above is to set each string to a variable, call the function with variables denoted by a literal dollar sign \$. Then in the function use eval to read the variable and output as expected.

#!/usr/bin/ksh

myFunction()
{
  eval string1="$1"
  eval string2="$2"
  eval string3="$3"

  echo "string1 = ${string1}"
  echo "string2 = ${string2}"
  echo "string3 = ${string3}"
}

var1="firstString"
var2="second string with spaces"
var3="thirdString"

myFunction "\${var1}" "\${var2}" "\${var3}"

exit 0

Output is then:

    string1 = firstString
    string2 = second string with spaces
    string3 = thirdString

In trying to solve a similar problem to this, I was running into the issue of UNIX thinking my variables were space delimeted. I was trying to pass a pipe delimited string to a function using awk to set a series of variables later used to create a report. I initially tried the solution posted by ghostdog74 but could not get it to work as not all of my parameters were being passed in quotes. After adding double-quotes to each parameter it then began to function as expected.

Below is the before state of my code and fully functioning after state.

Before - Non Functioning Code

#!/usr/bin/ksh

#*******************************************************************************
# Setup Function To Extract Each Field For The Error Report
#*******************************************************************************
getField(){
  detailedString="$1"
  fieldNumber=$2

  # Retrieves Column ${fieldNumber} From The Pipe Delimited ${detailedString} 
  #   And Strips Leading And Trailing Spaces
  echo ${detailedString} | awk -F '|' -v VAR=${fieldNumber} '{ print $VAR }' | sed 's/^[ \t]*//;s/[ \t]*$//'
}

while read LINE
do
  var1="$LINE"

  # Below Does Not Work Since There Are Not Quotes Around The 3
  iputId=$(getField "${var1}" 3)
done<${someFile}

exit 0

After - Functioning Code

#!/usr/bin/ksh

#*******************************************************************************
# Setup Function To Extract Each Field For The Report
#*******************************************************************************
getField(){
  detailedString="$1"
  fieldNumber=$2

  # Retrieves Column ${fieldNumber} From The Pipe Delimited ${detailedString} 
  #   And Strips Leading And Trailing Spaces
  echo ${detailedString} | awk -F '|' -v VAR=${fieldNumber} '{ print $VAR }' | sed 's/^[ \t]*//;s/[ \t]*$//'
}

while read LINE
do
  var1="$LINE"

  # Below Now Works As There Are Quotes Around The 3
  iputId=$(getField "${var1}" "3")
done<${someFile}

exit 0

This works fine with hostname, reverse IP (for internal networks) and IP.

function pingAddress($ip) {
    $ping = exec("ping -n 2 $ip", $output, $status);
    if (strpos($output[2], 'unreachable') !== FALSE) {
        return '<span style="color:#f00;">OFFLINE</span>';
    } else {
        return '<span style="color:green;">ONLINE</span>';
    }
}

echo pingAddress($ip);

I used a relative path in the xsi:noNamespaceSchemaLocation to provide the local xsd file (because I could not use a namespace in the instance xml).

<?xml version="1.0" encoding="UTF-8"?>
<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="../project/schema.xsd">
</root>

Validation works and the warning is fixed (not ignored).

This is a response I got from their Premium Services

Hello,

This is actually a issue with the way SSL validates names containing a period, '.', > character. We've documented this behavior here:

http://docs.amazonwebservices.com/AmazonS3/latest/dev/BucketRestrictions.html

The only straight-forward fix for this is to use a bucket name that does not contain that character. You might instead use a bucket named 'furniture-retailcatalog-us'. This would allow you use HTTPS with

https://furniture-retailcatalog-us.s3.amazonaws.com/

You could, of course, put a CNAME DNS record to make that more friendly. For example,

images-furniture.retailcatalog.us IN CNAME furniture-retailcatalog-us.s3.amazonaws.com.

Hope that helps. Let us know if you have any other questions.

Amazon Web Services

Unfortunately your "friendly" CNAME will cause host name mismatch when validating the certificate, therefore you cannot really use it for a secure connection. A big missing feature of S3 is accepting custom certificates for your domains.

UPDATE 10/2/2012

From @mpoisot:

The link Amazon provided no longer says anything about https. I poked around in the S3 docs and finally found a small note about it on the Virtual Hosting page: http://docs.amazonwebservices.com/AmazonS3/latest/dev/VirtualHosting.html

UPDATE 6/17/2013

From @Joseph Lust:

Similarly using rlang:

eval(parse_expr("5+5"))

You can just use numpy arrays. Look at the numpy for matlab users page for a detailed overview of the pros and cons of arrays w.r.t. matrices.

As I mentioned in the comment, having to use the dot() function or method for mutiplication of vectors is the biggest pitfall. But then again, numpy arrays are consistent. All operations are element-wise. So adding or subtracting arrays and multiplication with a scalar all work as expected of vectors.

Edit2: Starting with Python 3.5 and numpy 1.10 you can use the @ infix-operator for matrix multiplication, thanks to pep 465.

Edit: Regarding your comment:

1. Yes. The whole of numpy is based on arrays.

2. Yes. linalg.norm(v) is a good way to get the length of a vector. But what you get depends on the possible second argument to norm! Read the docs.

3. To normalize a vector, just divide it by the length you calculated in (2). Division of arrays by a scalar is also element-wise.

   An example in ipython:

   In [1]: import math
   
   In [2]: import numpy as np
   
   In [3]: a = np.array([4,2,7])
   
   In [4]: np.linalg.norm(a)
   Out[4]: 8.3066238629180749
   
   In [5]: math.sqrt(sum([n**2 for n in a]))
   Out[5]: 8.306623862918075
   
   In [6]: b = a/np.linalg.norm(a)
   
   In [7]: np.linalg.norm(b)
   Out[7]: 1.0
   

   Note that In [5] is an alternative way to calculate the length. In [6] shows normalizing the vector.

This is my quick trick:

from humanfriendly import format_timespan
secondsPassed = 1302
format_timespan(secondsPassed)
# '21 minutes and 42 seconds'

The key is "argument-less git-pull". When you do a git pull from a branch, without specifying a source remote or branch, git looks at the branch.<name>.merge setting to know where to pull from. git push -u sets this information for the branch you're pushing.

To see the difference, let's use a new empty branch:

$ git checkout -b test

First, we push without -u:

$ git push origin test
$ git pull
You asked me to pull without telling me which branch you
want to merge with, and 'branch.test.merge' in
your configuration file does not tell me, either. Please
specify which branch you want to use on the command line and
try again (e.g. 'git pull <repository> <refspec>').
See git-pull(1) for details.

If you often merge with the same branch, you may want to
use something like the following in your configuration file:

    [branch "test"]
    remote = <nickname>
    merge = <remote-ref>

    [remote "<nickname>"]
    url = <url>
    fetch = <refspec>

See git-config(1) for details.

Now if we add -u:

$ git push -u origin test
Branch test set up to track remote branch test from origin.
Everything up-to-date
$ git pull
Already up-to-date.

Note that tracking information has been set up so that git pull works as expected without specifying the remote or branch.

Update: Bonus tips:

• As Mark mentions in a comment, in addition to git pull this setting also affects default behavior of git push. If you get in the habit of using -u to capture the remote branch you intend to track, I recommend setting your push.default config value to upstream.
• git push -u <remote> HEAD will push the current branch to a branch of the same name on <remote> (and also set up tracking so you can do git push after that).

Is a simple MAYUS word. verify the log.

Use 404 if the resource does not exist. Don't return 200 with an empty body.

This is akin to undefined vs empty string (e.g. "") in programming. While very similar, there is definitely a difference.

404 means that nothing exists at that URI (like an undefined variable in programming). Returning 200 with an empty body means that something does exist there and that something is just empty right now (like an empty string in programming).

404 doesn't mean it was a "bad URI". There are special HTTP codes that are intended for URI errors (e.g. 414 Request-URI Too Long).

To select by class, you can do this:

$("input.className:checkbox:not(:checked)")

The answers provided so far using Jackson are so good, but still you could have a util function to help you convert different POJOs as follows:

    public static <T> T convert(Map<String, Object> aMap, Class<T> t) {
        try {
            return objectMapper
                    .convertValue(aMap, objectMapper.getTypeFactory().constructType(t));
        } catch (Exception e) {
            log.error("converting failed! aMap: {}, class: {}", getJsonString(aMap), t.getClass().getSimpleName(), e);
        }
        return null;
    }

when replaces the switch operator of C-like languages. In the simplest form it looks like this

when (x) {
    1 -> print("x == 1")
    2 -> print("x == 2")
    else -> {
        print("x is neither 1 nor 2")
    }
}

EDIT 2016-05-27 - loadRequest exposes "a universal Cross-Site Scripting vulnerability." Make sure you own every single asset that you load. If you load a bad script, it can load anything it wants.

If you need relative links to work locally, use this:

NSURL *url = [[NSBundle mainBundle] URLForResource:@"my" withExtension:@"html"];
[webView loadRequest:[NSURLRequest requestWithURL:url]];

The bundle will search all subdirectories of the project to find my.html. (the directory structure gets flattened at build time)

If my.html has the tag <img src="some.png">, the webView will load some.png from your project.

There is no collision in your example. You use the same key, so the old value gets replaced with the new one. Now, if you used two keys that map to the same hash code, then you'd have a collision. But even in that case, HashMap would replace your value! If you want the values to be chained in case of a collision, you have to do it yourself, e.g. by using a list as a value.

Do you want to open a shared folder in Windows Explorer? You need to use a file: link, but there are caveats:

• Internet Explorer will work if the link is a converted UNC path (file://server/share/folder/).
• Firefox will work if the link is in its own mangled form using five slashes (file://///server/share/folder) and the user has disabled the security restriction on file: links in a page served over HTTP. Thankfully IE also accepts the mangled link form.
• Opera, Safari and Chrome can not be convinced to open a file: link in a page served over HTTP.

You can create a character array that does this via a loop:

>> for i=1:10
Names(i,:)='Sample Text';
end
>> Names

Names =

Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text

However, this would be better implemented using REPMAT:

>> Names = repmat('Sample Text', 10, 1)

Names =

Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text

With JTable.AUTO_RESIZE_OFF, the table will not change the size of any of the columns for you, so it will take your preferred setting. If it is your goal to have the columns default to your preferred size, except to have the last column fill the rest of the pane, You have the option of using the JTable.AUTO_RESIZE_LAST_COLUMN autoResizeMode, but it might be most effective when used with TableColumn.setMaxWidth() instead of TableColumn.setPreferredWidth() for all but the last column.

Once you are satisfied that AUTO_RESIZE_LAST_COLUMN does in fact work, you can experiment with a combination of TableColumn.setMaxWidth() and TableColumn.setMinWidth()

Thought I knew I had read about that in the standard; but can't find it. Keeps looking. Old; answering heading; not Q-tex ;P:

The following program would determine that:

#include <stdio.h>
#include <stdint.h>

int is_big_endian(void)
{
    union {
        uint32_t i;
        char c[4];
    } e = { 0x01000000 };

    return e.c[0];
}

int main(void)
{
    printf("System is %s-endian.\n",
        is_big_endian() ? "big" : "little");

    return 0;
}

You also have this approach; from Quake II:

byte    swaptest[2] = {1,0};
if ( *(short *)swaptest == 1) {
    bigendien = false;

And !is_big_endian() is not 100% to be little as it can be mixed/middle.

Believe this can be checked using same approach only change value from 0x01000000 to i.e. 0x01020304 giving:

switch(e.c[0]) {
case 0x01: BIG
case 0x02: MIX
default: LITTLE

But not entirely sure about that one ...

Also add this bit of code to your form to allow it to be draggable still.

Just add it right before the constructor (the method that calls InitializeComponent()

private const int WM_NCHITTEST = 0x84;
private const int HTCLIENT = 0x1;
private const int HTCAPTION = 0x2;

///
/// Handling the window messages
///
protected override void WndProc(ref Message message)
{
    base.WndProc(ref message);

    if (message.Msg == WM_NCHITTEST && (int)message.Result == HTCLIENT)
        message.Result = (IntPtr)HTCAPTION;
}

That code is from: https://jachman.wordpress.com/2006/06/08/enhanced-drag-and-move-winforms-without-having-a-titlebar/

Now to get rid of the title bar but still have a border combine the code from the other response:

this.ControlBox = false;

this.Text = String.Empty;

with this line:

this.FormBorderStyle = FormBorderStyle.FixedSingle;

Put those 3 lines of code into the form's OnLoad event and you should have a nice 'floating' form that is draggable with a thin border (use FormBorderStyle.None if you want no border).

Hmm, I would suggest that you use Flyweight to implement the states. Purpose: Avoid the memory overhead of a large number of small objects. State machines can get very, very big.

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

I'm not sure that I see the need to use design pattern State to implement the nodes. The nodes in a state machine are stateless. They just match the current input symbol to the available transitions from the current state. That is, unless I have entirely forgotten how they work (which is a definite possiblilty).

If I were coding it, I would do something like this:

interface FsmNode {
  public boolean canConsume(Symbol sym);
  public FsmNode consume(Symbol sym);
  // Other methods here to identify the state we are in
}

  List<Symbol> input = getSymbols();
  FsmNode current = getStartState();
  for (final Symbol sym : input) {
    if (!current.canConsume(sym)) {
      throw new RuntimeException("FSM node " + current + " can't consume symbol " + sym);
    }
    current = current.consume(sym);
  }
  System.out.println("FSM consumed all input, end state is " + current);

What would Flyweight do in this case? Well, underneath the FsmNode there would probably be something like this:

Map<Integer, Map<Symbol, Integer>> fsm; // A state is an Integer, the transitions are from symbol to state number
FsmState makeState(int stateNum) {
  return new FsmState() {
    public FsmState consume(final Symbol sym) {
      final Map<Symbol, Integer> transitions = fsm.get(stateNum);
      if (transisions == null) {
        throw new RuntimeException("Illegal state number " + stateNum);
      }
      final Integer nextState = transitions.get(sym);  // May be null if no transition
      return nextState;
    }
    public boolean canConsume(final Symbol sym) {
      return consume(sym) != null;
    }
  }
}

This creates the State objects on a need-to-use basis, It allows you to use a much more efficient underlying mechanism to store the actual state machine. The one I use here (Map(Integer, Map(Symbol, Integer))) is not particulary efficient.

Note that the Wikipedia page focuses on the cases where many somewhat similar objects share the similar data, as is the case in the String implementation in Java. In my opinion, Flyweight is a tad more general, and covers any on-demand creation of objects with a short life span (use more CPU to save on a more efficient underlying data structure).

To replace na values in pandas

df['column_name'].fillna(value_to_be_replaced,inplace=True)

if inplace = False, instead of updating the df (dataframe) it will return the modified values.

In my case I was getting the alias name wrong, even though I stored the correct password. So I thought it was the wrong password (using ionic package) so i used this command to get the alias name

keytool -list -v -keystore

And I was able to use the keystore again!

You have an extra '{' before return type. You may also want to put '==' instead of '=' in if and else condition.

I would recommend looking at this article on how to use javascript to handle basic formatting:

function addCommas(nStr)
{
    nStr += '';
    x = nStr.split('.');
    x1 = x[0];
    x2 = x.length > 1 ? '.' + x[1] : '';
    var rgx = /(\d+)(\d{3})/;
    while (rgx.test(x1)) {
        x1 = x1.replace(rgx, '$1' + ',' + '$2');
    }
    return x1 + x2;
}

While jQuery can make your life easier in a million different ways I would say it's overkill for this. Keep in mind that jQuery can be fairly large and your user's browser needs to download it when you use it on a page.

When ever using jQuery you should step back and ask if it contributes enough to justify the extra overhead of downloading the library.

If you need some sort of advanced formatting (like the localization stuff in the plugin you linked), or you are already including jQuery it might be worth looking at a jQuery plugin.

Side note - check this out if you want to get a chuckle about the over use of jQuery.

I had to do it slightly different to work for me:

1. rightclick project, remove maven nature (or in newer eclipse, "Maven->Disable Maven Nature")
2. mvn eclipse:clean (with project open in eclipse/STS)
3. delete the project in eclipse (but do not delete the sources)
4. Import existing Maven project

as KingCrunch pointed out, using phpinfo you can see what config file is in action in the "Loaded Configuration File" row. in my case in was in C:\xampp\apache\bin note that there is a php.ini also in C:\xampp\php which seems to be redundant and irrelevant

You can call more than one target goal with maven. mvn clean install calls clean first, then install. You have to clean manually, because clean is not a standard target goal and not executed automatically on every install.

clean removes the target folder - it deletes all class files, the java docs, the jars, reports and so on. If you don't clean, then maven will only "do what has to be done", like it won't compile classes when the corresponding source files haven't changed (in brief).

^{we call it target in ant and goal in maven}

https://developer.mozilla.org/en/CSS/Media_queries#-moz-device-pixel-ratio

-moz-device-pixel-ratio
Gives the number of device pixels per CSS pixel.

this is almost self-explaining. the number describes the ratio of how much "real" pixels (physical pixerls of the screen) are used to display one "virtual" pixel (size set in CSS).

In Oracle DB:

create table temp_test1 (id number, value number, description varchar2(20));

insert into temp_test1 values(1, 22, 'qq');
insert into temp_test1 values(2, 22, 'qq');
insert into temp_test1 values(3, 22, 'qq');
insert into temp_test1 values(4, 23, 'qq1');
insert into temp_test1 values(5, 23, 'qq1');
insert into temp_test1 values(6, 23, 'qq1');

SELECT MAX(id), value, description FROM temp_test1 GROUP BY value, description;

Result:
    MAX(ID) VALUE DESCRIPTION
    -------------------------
    6         23    qq1
    3         22    qq

Additionally to IIDan's answer: For some purposes it is necessary to set

label.layer.shouldRasterize = YES

I think this is due to the blend mode that is used to render the shadow. For example I had a dark background and white text on it and wanted to "highlight" the text using a black shadowy glow. It wasn't working until I set this property.

Justin's answer did not work for me (Chromium 18, Firefox 43.0.1). jQuery's .focus() creates visual highlight, but text cursor does not appear in the field (jquery 3.1.0).

Inspired by https://www.sitepoint.com/jqueryhtml5-input-focus-cursor-positions/ , I added autofocus attribute to the input field and voila!

function addfield() {
    n=$('table tr').length;
    $('table').append('<tr><td><input name=field'+n+' autofocus></td><td><input name=value'+n+'></td></tr>');
    $('input[name="aa"'+n+']').focus();
}

bash does not abort the running execution in case something detects an error state (unless you set the -e flag). Programming languages which offer try/catch do this in order to inhibit a "bailing out" because of this special situation (hence typically called "exception").

In the bash, instead, only the command in question will exit with an exit code greater than 0, indicating that error state. You can check for that of course, but since there is no automatic bailing out of anything, a try/catch does not make sense. It is just lacking that context.

You can, however, simulate a bailing out by using sub shells which can terminate at a point you decide:

(
  echo "Do one thing"
  echo "Do another thing"
  if some_condition
  then
    exit 3  # <-- this is our simulated bailing out
  fi
  echo "Do yet another thing"
  echo "And do a last thing"
)   # <-- here we arrive after the simulated bailing out, and $? will be 3 (exit code)
if [ $? = 3 ]
then
  echo "Bail out detected"
fi

Instead of that some_condition with an if you also can just try a command, and in case it fails (has an exit code greater than 0), bail out:

(
  echo "Do one thing"
  echo "Do another thing"
  some_command || exit 3
  echo "Do yet another thing"
  echo "And do a last thing"
)
...

Unfortunately, using this technique you are restricted to 255 different exit codes (1..255) and no decent exception objects can be used.

If you need more information to pass along with your simulated exception, you can use the stdout of the subshells, but that is a bit complicated and maybe another question ;-)

Using the above mentioned -e flag to the shell you can even strip that explicit exit statement:

(
  set -e
  echo "Do one thing"
  echo "Do another thing"
  some_command
  echo "Do yet another thing"
  echo "And do a last thing"
)
...

In Mac, for me this works:
