You could try the following:

import matplotlib.pyplot as plt
import numpy as np

def plot_figures(figures, nrows = 1, ncols=1):
    """Plot a dictionary of figures.

    Parameters
    ----------
    figures : <title, figure> dictionary
    ncols : number of columns of subplots wanted in the display
    nrows : number of rows of subplots wanted in the figure
    """

    fig, axeslist = plt.subplots(ncols=ncols, nrows=nrows)
    for ind,title in zip(range(len(figures)), figures):
        axeslist.ravel()[ind].imshow(figures[title], cmap=plt.jet())
        axeslist.ravel()[ind].set_title(title)
        axeslist.ravel()[ind].set_axis_off()
    plt.tight_layout() # optional



# generation of a dictionary of (title, images)
number_of_im = 20
w=10
h=10
figures = {'im'+str(i): np.random.randint(10, size=(h,w)) for i in range(number_of_im)}

# plot of the images in a figure, with 5 rows and 4 columns
plot_figures(figures, 5, 4)

plt.show()

However, this is basically just copy and paste from here: Multiple figures in a single window for which reason this post should be considered to be a duplicate.

I hope this helps.

When getting "File not found", my problem was that there was no symlink in the folder where was pointing this line in ngix config:

You can set custom font in two ways : design time and run-time.

1. First you need to download required font (.ttf file format). Then, double click on the file to install it.

2. This will show a pop-up. Click on 'install font' button.

3. This will install the font and will appear in 'Fonts' window.

4. Now, the font is installed successfully. Drag and drop the custom font in your project. While doing this make sure that 'Add to targets' is checked.

5. You need to make sure that this file is also added into 'Copy Bundle Resources' present in Build Phases of Targets of your project.

6. After this you need to add this font in Info.plist of your project. Create a new key with 'Font Provided by application' with type as Array. Add a the font as an element with type String in Array.

A. Design mode :

7. Select the label from Storyboard file. Goto Font attribute present in Attribute inspector of Utilities.

8. Click on Font and select 'Custom font'

9. From Family section select the custom font you have installed.

10. Now you can see that font of label is set to custom font.

B. Run-time mode :

 self.lblWelcome.font = UIFont(name: "BananaYeti-Extrabold Trial", size: 16)

It seems that run-time mode doesn't work for dynamically formed string like

self.lblWelcome.text = "Welcome, " + fullname + "!"

Note that in above case only design-time approach worked correctly for me.

Passive event listeners are an emerging web standard, new feature shipped in Chrome 51 that provide a major potential boost to scroll performance. Chrome Release Notes.

It enables developers to opt-in to better scroll performance by eliminating the need for scrolling to block on touch and wheel event listeners.

Problem: All modern browsers have a threaded scrolling feature to permit scrolling to run smoothly even when expensive JavaScript is running, but this optimization is partially defeated by the need to wait for the results of any touchstart and touchmove handlers, which may prevent the scroll entirely by calling preventDefault() on the event.

Solution: {passive: true}

By marking a touch or wheel listener as passive, the developer is promising the handler won't call preventDefault to disable scrolling. This frees the browser up to respond to scrolling immediately without waiting for JavaScript, thus ensuring a reliably smooth scrolling experience for the user.

document.addEventListener("touchstart", function(e) {
    console.log(e.defaultPrevented);  // will be false
    e.preventDefault();   // does nothing since the listener is passive
    console.log(e.defaultPrevented);  // still false
}, Modernizr.passiveeventlisteners ? {passive: true} : false);

I had the same problem with SQLite and Android. Here is my Solution:

List<String> tables = new ArrayList<String>();
Cursor cursor = db.rawQuery("SELECT * FROM sqlite_master WHERE type='table';", null);
cursor.moveToFirst();
while (!cursor.isAfterLast()) {
    String tableName = cursor.getString(1);
    if (!tableName.equals("android_metadata") &&
            !tableName.equals("sqlite_sequence"))
        tables.add(tableName);
    cursor.moveToNext();
}
cursor.close();

for(String tableName:tables) {
    db.execSQL("DROP TABLE IF EXISTS " + tableName);
}

If you are using it in a table use this :-

  <script type="text/javascript">
   function showStuff(id, text, btn) {
    document.getElementById(id).style.display = 'table-row';
    // hide the lorem ipsum text
    document.getElementById(text).style.display = 'none';
    // hide the link
    btn.style.display = 'none';
}
</script>


<td class="post">

<a href="#" onclick="showStuff('answer1', 'text1', this); return false;">Edit</a>
<span id="answer1" style="display: none;">
<textarea rows="10" cols="115"></textarea>
</span>

<span id="text1">Lorem ipsum Lorem ipsum Lorem ipsum Lorem ipsum</span>
</td>

use this filter:

(dns.flags.response == 0) and (ip.src == 159.25.78.7)

what this query does is it only gives dns queries originated from your ip

This is how it worked for me:

I ran the below command
sudo install_name_tool -change libmysqlclient.18.dylib /usr/local/mysql/lib/libmysqlclient.18.dylib ~/.rvm/gems/ruby-1.9.2-p180/gems/mysql2-0.2.7/lib/mysql2/mysql2.bundle

My environments:
$ rails -v Rails 3.0.6

$ mysql --version
mysql Ver 14.14 Distrib 5.5.11, for osx10.6 (i386) using readline 5.1

$ ruby -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-darwin10.7.0]

Hope this helps someone.

Change your code to.

<?php
$sqlupdate1 = "UPDATE table SET commodity_quantity=".$qty."WHERE user=".$rows['user'];
?>

There was syntax error in your query.

I think this is the easiest and shortest solution to running a batch file without opening the DOS window, it can be very distracting when you want to schedule a set of commands to run periodically, so the DOS window keeps popping up, here is your solution. Use a VBS Script to call the batch file ...

Set WshShell = CreateObject("WScript.Shell" ) 
WshShell.Run chr(34) & "C:\Batch Files\ mycommands.bat" & Chr(34), 0 
Set WshShell = Nothing 

Copy the lines above to an editor and save the file with .VBS extension. Edit the .BAT file name and path accordingly.

Since link to this question shows up on very top of returned results when you search for "php MSVCR110.dll" (not to mention it got 100k+ views and growing), here're some additional notes that you may find handy in your quest to solve MSVCR110.dll mistery...

The approach described in the answer is valid not only for MSVCR110.dll case but also applies when you are looking for other versions, like newer MSVCR71.dll and I updated the answer to include VC15 even it's beyond scope of the original question.

On http://windows.php.net/ you can read:

VC9, VC11 and VC15

More recent versions of PHP are built with VC9, VC11 or VC15 (Visual Studio 2008, 2012 or 2015 compiler respectively) and include improvements in performance and stability.

The VC9 builds require you to have the Visual C++ Redistributable for Visual Studio 2008 SP1 x86 or x64 installed.

The VC11 builds require to have the Visual C++ Redistributable for Visual Studio 2012 x86 or x64 installed.

The VC15 builds require to have the Visual C++ Redistributable for Visual Studio 2015 x86 or x64 installed.

This is quite crucial as you not only need to get Visual C++ Redistributable installed but you also need the right version of it, and which one is right and correct, depends on what PHP build you are actually going to use. Pay attention to what version of PHP for Windows you are fetching, especially pay attention to this "VCxx" suffix, because if you install PHP that requires VC9 while having redistributables VC11 installed it is not going to work as run-time dependency is simply not fulfilled. Contrary to what some may think, you need exactly the version required, as newer (higher) releases does NOT cover older (lower) versions. so i.e. VC11 is not providing VC9 compatibility. Also VC15 is neither fulfilling VC11 nor VC9 dependency. It is just VC15 and NOTHING ELSE. Deal with it :)

For example, archive name php-5.6.4-nts-Win32-VC11-x86 tells us the following

1. it provides PHP v5.6.4,
2. PHP build is Non-Thread Safe (nts),
3. it provides binaries for Windows (Win32),
4. to run, Visual Studio 2012 redistributable (VC11) is required,
5. binaries are 32-bit (x86),

Most searches I did lead to VC9 of redistributables, so in case of constant failures to make thing works, if possible, try installing different PHP build, to see if you by any chance do not face mismatching versions.

Download links

Note that you are using 32-bit version of PHP, so you need 32-bit redistributable (x86) even if your version of Windows is 64-bit!

• VC9: Visual C++ Redistributable for Visual Studio 2008: x86 or x64
• VC11: Visual C++ Redistributable for Visual Studio 2012: x86 or x64
• VC15: Visual C++ Redistributable for Visual Studio 2015: x86 or x64
• VC17: Visual C++ Redistributable for Visual Studio 2017: x86 or x64

This is an old question, but comes out high in my Google search for 'perl merge hashes' - and yet it does not mention the very helpful CPAN module Hash::Merge

If that's what you want to do, it would be better to use if statements. For example:

if(liCount == 0){
    setLayoutState('start');
}
if(liCount<=5 && liCount>0){
    setLayoutState('upload1Row');
}
if(liCount<=10 && liCount>5){
    setLayoutState('upload2Rows');
}             
var api = $('#UploadList').data('jsp');
    api.reinitialise();

A bit late to the party, but Krux has created a script for this, called Postscribe. We were able to use this to get past this issue.

With the cli I don't know if it's a remove command but you can remove it from package.json and stop using it in your code.If you reinstall the packages you wilk not have it any more

There is the Math.pow(double a, double b) method. Note that it returns a double, you will have to cast it to an int like (int)Math.pow(double a, double b).

We can achieve this with these multiple ways:-

XML method 01

<TextView  
    android:id="@+id/textView"
    android:layout_height="match_parent"
    android:layout_width="wrap_content" 
    android:gravity="center_vertical|center_horizontal"
    android:text="@strings/text"
/>

XML method 02

<TextView  
    android:id="@+id/textView"
    android:layout_height="match_parent"
    android:layout_width="wrap_content" 
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:text="@strings/text"
/>

XML method 03

<TextView  
    android:id="@+id/textView"
    android:layout_height="match_parent"
    android:layout_width="wrap_content" 
    android:gravity="center"
    android:text="@strings/text"
/>

XML method 04

<TextView  
    android:id="@+id/textView"
    android:layout_height="match_parent"
    android:layout_width="wrap_content" 
    android:layout_centerInParent="true"
    android:text="@strings/text"
/>

Java method 01

textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);

Java method 02

textview.setGravity(Gravity.CENTER);

Java method 03

textView.setTextAlignment(View.TEXT_ALIGNMENT_CENTER);

Unfortunately, you can't change the font size or styling in a drop-down list that is created using data validation.

You can style the text in a combo box, however. Follow the instructions here: Excel Data Validation Combo Box

Just drop the option v.

-v is for verbose. If you don't use it then it won't display:

tar -zxf tmp.tar.gz -C ~/tmp1

I have the same problem and I just used cin.getline(input,300);.

noskipws and cin.get() sometimes are not easy to use. Since you have the right size of your array try using cin.getline() which does not care about any character and read the whole line in specified character count.

Let me solve this question with a practical example in the form of a simple dice rolling app that calls 1 of 6 dice face images randomly to the screen when tapped.

first declare a variable that generates random numbers (don't forget to import dart.math). Then declare a variable that parses the initial random number within constraints between 1 and 6 as an Integer.

Both variables are static private in order to be initialized once.This is is not a huge deal but would be good practice if you had to initialize a whole bunch of random numbers.

static var _random = new Random();
static var _diceface = _random.nextInt(6) +1 ;

Now create a Gesture detection widget with a ClipRRect as a child to return one of the six dice face images to the screen when tapped.

GestureDetector(
          onTap: () {
            setState(() {
              _diceface = _rnd.nextInt(6) +1 ;
            });
          },
          child: ClipRRect(
            clipBehavior: Clip.hardEdge,
            borderRadius: BorderRadius.circular(100.8),
              child: Image(
                image: AssetImage('images/diceface$_diceface.png'),
                fit: BoxFit.cover,
              ),
          )
        ),

A new random number is generated each time you tap the screen and that number is referenced to select which dice face image is chosen.

I hoped this example helped :)

Dice rolling app using random numbers in dart

Data::Dumper is your friend.

use Data::Dumper;
my %hash = ('abc' => 123, 'def' => [4,5,6]);
print Dumper(\%hash);

will output

$VAR1 = {
          'def' => [
                     4,
                     5,
                     6
                   ],
          'abc' => 123
        };

Filename=url.java

public class url {

    public static final String BASEURL = "http://192.168.1.122/";

}

if u want to call the variable just use this:

url.BASEURL + "your code here";

Exit code at one point. That provides better readability to code. Adding return statements (Multiple exits) in between will make debugging difficult .

Try another cable and if that doesn't work try another phone.

I wrestled with this and all the tips above for several days. But the connector on my devices was flakey. As a test move the phone and see if you get connections dropping.

Some of the tips such a ADB USB will fix it temporarily and explicitly (re) selecting the device process to debug. But for me the root cause was that the physical connection.

So now with the new device I have no problem ever! A flakey cable would cause the same issue. Good luck! I feel your pain.

When you define any variable then you do not have to put in any extra spaces.

E.g.

name = "Stack Overflow"  
// it is not valid, you will get an error saying- "Command not found"

So remove spaces:

name="Stack Overflow" 

and it will work fine.

I recommand the following article : Hit Region Detection For HTML5 Canvas And How To Listen To Click Events On Canvas Shapes which goes through various situations.

However, it does not cover the addHitRegion API, which must be the best way (using math functions and/or comparisons is quite error prone). This approach is detailed on developer.mozilla

The URL structure you're referring to is called the REST endpoint, as opposed to the Web Site Endpoint.

Note: Since this answer was originally written, S3 has rolled out dualstack support on REST endpoints, using new hostnames, while leaving the existing hostnames in place. This is now integrated into the information provided, below.

If your bucket is really in the us-east-1 region of AWS -- which the S3 documentation formerly referred to as the "US Standard" region, but was subsequently officially renamed to the "U.S. East (N. Virginia) Region" -- then http://s3-us-east-1.amazonaws.com/bucket/ is not the correct form for that endpoint, even though it looks like it should be. The correct format for that region is either http://s3.amazonaws.com/bucket/ or http://s3-external-1.amazonaws.com/bucket/.¹

The format you're using is applicable to all the other S3 regions, but not US Standard US East (N. Virginia) [us-east-1].

S3 now also has dual-stack endpoint hostnames for the REST endpoints, and unlike the original endpoint hostnames, the names of these have a consistent format across regions, for example s3.dualstack.us-east-1.amazonaws.com. These endpoints support both IPv4 and IPv6 connectivity and DNS resolution, but are otherwise functionally equivalent to the existing REST endpoints.

If your permissions and configuration are set up such that the web site endpoint works, then the REST endpoint should work, too.

However... the two endpoints do not offer the same functionality.

Roughly speaking, the REST endpoint is better-suited for machine access and the web site endpoint is better suited for human access, since the web site endpoint offers friendly error messages, index documents, and redirects, while the REST endpoint doesn't. On the other hand, the REST endpoint offers HTTPS and support for signed URLs, while the web site endpoint doesn't.

Choose the correct type of endpoint (REST or web site) for your application:

http://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteEndpoints.html#WebsiteRestEndpointDiff

¹ s3-external-1.amazonaws.com has been referred to as the "Northern Virginia endpoint," in contrast to the "Global endpoint" s3.amazonaws.com. It was unofficially possible to get read-after-write consistency on new objects in this region if the "s3-external-1" hostname was used, because this would send you to a subset of possible physical endpoints that could provide that functionality. This behavior is now officially supported on this endpoint, so this is probably the better choice in many applications. Previously, s3-external-2 had been referred to as the "Pacific Northwest endpoint" for US-Standard, though it is now a CNAME in DNS for s3-external-1 so s3-external-2 appears to have no purpose except backwards-compatibility.

Per Truth value testing, 'None' directly tests as FALSE, so the simplest expression will suffice:

if not foo:

Yes:

<input required title="Enter something OR ELSE." /> 

The title attribute will be used to notify the user of a problem.

hr {
    border-top:1px dotted #000;
    /*Rest of stuff here*/
}

Perhaps you can try to BeginInvoke a delegate pointing to your method like so:

    delegate string SynchOperation(string value);

    class Program
    {
        static void Main(string[] args)
        {
            BeginTheSynchronousOperation(CallbackOperation, "my value");
            Console.ReadLine();
        }

        static void BeginTheSynchronousOperation(AsyncCallback callback, string value)
        {
            SynchOperation op = new SynchOperation(SynchronousOperation);
            op.BeginInvoke(value, callback, op);
        }

        static string SynchronousOperation(string value)
        {
            Thread.Sleep(10000);
            return value;
        }

        static void CallbackOperation(IAsyncResult result)
        {
            // get your delegate
            var ar = result.AsyncState as SynchOperation;
            // end invoke and get value
            var returned = ar.EndInvoke(result);

            Console.WriteLine(returned);
        }
    }

Then use the value in the method you sent as AsyncCallback to continue..

You can use split method for it. And if you should take string from specific pattern you can use split with req. exp.:

var string = "sometext-20202";
console.log(string.split(/-(.*)/)[1])

This answer is correct for old versions of iOS, but is now obsolete. You should use Micky Duncan's answer, which covers custom containers.

Don't do this! The intent of the UIViewController is to drive the entire screen. It just isn't appropriate for this, and it doesn't really add anything you need.

All you need is an object that owns your custom view. Just use a subclass of UIView itself, so it can be added to your window hierarchy and the memory management is fully automatic.

Point the subview NIB's owner a custom subclass of UIView. Add a contentView outlet to this custom subclass, and point it at the view within the nib. In the custom subclass do something like this:

- (id)initWithFrame: (CGRect)inFrame;
{
    if ( (self = [super initWithFrame: inFrame]) ) {
        [[NSBundle mainBundle] loadNibNamed: @"NibNameHere"
                                      owner: self
                                    options: nil];
        contentView.size = inFrame.size;
        // do extra loading here
        [self addSubview: contentView];
    }
    return self;
}

- (void)dealloc;
{
    self.contentView = nil;
    // additional release here
    [super dealloc];
}

(I'm assuming here you're using initWithFrame: to construct the subview.)

Every object inherits __repr__ from the base class that all objects created.

class Person:
     pass

p=Person()

if you call repr(p) you will get this as default:

 <__main__.Person object at 0x7fb2604f03a0>

But if you call str(p) you will get the same output. it is because when __str__ does not exist, Python calls __repr__

Let's implement our own __str__

class Person:
    def __init__(self,name,age):
        self.name=name
        self.age=age
    def __repr__(self):
        print("__repr__ called")
        return f"Person(name='{self.name}',age={self.age})"

p=Person("ali",20)

print(p) and str(p)will return

 __repr__ called
     Person(name='ali',age=20)

let's add __str__()

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age
        
    def __repr__(self):
        print('__repr__ called')
        return f"Person(name='{self.name}, age=self.age')"
    
    def __str__(self):
        print('__str__ called')
        return self.name

p=Person("ali",20)

if we call print(p) and str(p), it will call __str__() so it will return

__str__ called
ali

repr(p) will return

repr called "Person(name='ali, age=self.age')"

Let's omit __repr__ and just implement __str__.

class Person:
def __init__(self, name, age):
    self.name = name
    self.age = age

def __str__(self):
    print('__str__ called')
    return self.name

p=Person('ali',20)

print(p) will look for the __str__ and will return:

__str__ called
ali

NOTE= if we had __repr__ and __str__ defined, f'name is {p}' would call __str__

int i = 0; // Counter used to determine when you're at the 3rd gun
for (Gun g : gunList) { // For each gun in your list
    System.out.println(g); // Print out the gun
    if (i == 2) { // If you're at the third gun
        ArrayList<Bullet> bullets = g.getBullet(); // Get the list of bullets in the gun
        for (Bullet b : bullets) { // Then print every bullet
            System.out.println(b);
        }
    i++; // Don't forget to increment your counter so you know you're at the next gun
}

If you use node.js 0.12 or above / typescript 1.4 or above, just add compiler options like:

tsc a.ts --target es6 --module commonjs

More info: https://github.com/Microsoft/TypeScript/wiki/Compiler-Options

If you use tsconfig.json, then like this:

{
    "compilerOptions": {
        "module": "commonjs",
        "target": "es6"
    }
}

More info: https://github.com/Microsoft/TypeScript/wiki/tsconfig.json

you would have to do something like this:

objArray.sort(function(a, b) {
    var textA = a.DepartmentName.toUpperCase();
    var textB = b.DepartmentName.toUpperCase();
    return (textA < textB) ? -1 : (textA > textB) ? 1 : 0;
});

note: changing the case (to upper or lower) ensures a case insensitive sort.

You can't easily decrypt the password from the hash string that you see. You should rather replace the hash string with a new one from a password that you do know.

There's a good howto here:

https://jakebillo.com/wordpress-phpass-generator-resetting-or-creating-a-new-admin-user/

Basically:

1. generate a new hash from a known password using e.g. http://scriptserver.mainframe8.com/wordpress_password_hasher.php, as described in the above link, or any other product that uses the phpass library,
2. use your DB interface (e.g. phpMyAdmin) to update the user_pass field with the new hash string.

If you have more users in this WordPress installation, you can also copy the hash string from one user whose password you know, to the other user (admin).

You can specify multiple method signatures on the interface then have multiple method overloads on the class method:

interface INotificationService {
    error(message: string, title?: string, autoHideAfter?: number);
    error(message: string, autoHideAfter: number);
}

class MyNotificationService implements INotificationService {
    error(message: string, title?: string, autoHideAfter?: number);
    error(message: string, autoHideAfter?: number);
    error(message: string, param1?: (string|number), param2?: number) {
        var autoHideAfter: number,
            title: string;

        // example of mapping the parameters
        if (param2 != null) {
            autoHideAfter = param2;
            title = <string> param1;
        }
        else if (param1 != null) {
            if (typeof param1 === "string") {
                title = param1;
            }
            else {
                autoHideAfter = param1;
            }
        }

        // use message, autoHideAfter, and title here
    }
}

Now all these will work:

var service: INotificationService = new MyNotificationService();
service.error("My message");
service.error("My message", 1000);
service.error("My message", "My title");
service.error("My message", "My title", 1000);

...and the error method of INotificationService will have the following options:

Restartable mode (/Z) has to do with a partially-copied file. With this option, should the copy be interrupted while any particular file is partially copied, the next execution of robocopy can pick up where it left off rather than re-copying the entire file.

That option could be useful when copying very large files over a potentially unstable connection.

Backup mode (/B) has to do with how robocopy reads files from the source system. It allows the copying of files on which you might otherwise get an access denied error on either the file itself or while trying to copy the file's attributes/permissions. You do need to be running in an Administrator context or otherwise have backup rights to use this flag.

Short version which you can pass to kill command:

lsof -i:80 -t

Here's a quick overview:

• Once references are gone, your object will likely be garbage collected.
• You can only count on statistical collection that keeps your heap size normal provided all references to garbage are really gone. In other words, there is no guarantee a specific object will ever be garbage collected.
  • It follows that your finalizer will also never be guaranteed to be called. Avoid finalizers.
• Two common sources of leaks:
  • Event handlers and delegates are references. If you subscribe to an event of an object, you are referencing to it. If you have a delegate to an object's method, you are referencing it.
  • Unmanaged resources, by definition, are not automatically collected. This is what the IDisposable pattern is for.
• Finally, if you want a reference that does not prevent the object from getting collected, look into WeakReference.

One last thing: If you declare Foo foo; without assigning it you don't have to worry - nothing is leaked. If Foo is a reference type, nothing was created. If Foo is a value type, it is allocated on the stack and thus will automatically be cleaned up.

I think you have to calculate latitudine min and longitude min: Here is an Example with the function to use to center your point:

//Example values of min & max latlng values
var lat_min = 1.3049337;
var lat_max = 1.3053515;
var lng_min = 103.2103116;
var lng_max = 103.8400188;

map.setCenter(new google.maps.LatLng(
  ((lat_max + lat_min) / 2.0),
  ((lng_max + lng_min) / 2.0)
));
map.fitBounds(new google.maps.LatLngBounds(
  //bottom left
  new google.maps.LatLng(lat_min, lng_min),
  //top right
  new google.maps.LatLng(lat_max, lng_max)
));

int count = 0;
foreach (ListViewItem lvi in listView.Items)
{
    if(++count > 50) break;
}

It needs to be a jQuery element to use .addClass(), so it needs to be wrapped in $() like this:

function addClassByClick(button){
  $(button).addClass("active")
}

A better overall solution would be unobtrusive script, for example:

<asp:Button ID="Button" runat="server" class="clickable"/>

Then in jquery:

$(function() {                       //run when the DOM is ready
  $(".clickable").click(function() {  //use a class, since your ID gets mangled
    $(this).addClass("active");      //add the class to the clicked element
  });
});

Compiling and running a Java application on Mac OSX, or any major operating system, is very easy. Apple includes a fully-functional Java runtime and development environment out-of-the-box with OSX, so all you have to do is write a Java program and use the built-in tools to compile and run it.

Writing Your First Program

The first step is writing a simple Java program. Open up a text editor (the built-in TextEdit app works fine), type in the following code, and save the file as "HelloWorld.java" in your home directory.

public class HelloWorld {
    public static void main(String args[]) {
        System.out.println("Hello World!");
    }
}

For example, if your username is David, save it as "/Users/David/HelloWorld.java". This simple program declares a single class called HelloWorld, with a single method called main. The main method is special in Java, because it is the method the Java runtime will attempt to call when you tell it to execute your program. Think of it as a starting point for your program. The System.out.println() method will print a line of text to the screen, "Hello World!" in this example.

Using the Compiler

Now that you have written a simple Java program, you need to compile it. Run the Terminal app, which is located in "Applications/Utilities/Terminal.app". Type the following commands into the terminal:

cd ~
javac HelloWorld.java

You just compiled your first Java application, albeit a simple one, on OSX. The process of compiling will produce a single file, called "HelloWorld.class". This file contains Java byte codes, which are the instructions that the Java Virtual Machine understands.

Running Your Program

To run the program, type the following command in the terminal.

java HelloWorld

This command will start a Java Virtual Machine and attempt to load the class called HelloWorld. Once it loads that class, it will execute the main method I mentioned earlier. You should see "Hello World!" printed in the terminal window. That's all there is to it.

As a side note, TextWrangler is just a text editor for OSX and has no bearing on this situation. You can use it as your text editor in this example, but it is certainly not necessary.

The volatile keyword is used:

• to make non atomic 64-bit operations atomic: long and double. (all other, primitive accesses are already guaranteed to be atomic!)
• to make variable updates guaranteed to be seen by other threads + visibility effects: after writing to a volatile variable, all the variables that where visible before writing that variable become visible to another thread after reading the same volatile variable (happen-before ordering).

The java.util.concurrent.atomic.* classes are, according to the java docs:

A small toolkit of classes that support lock-free thread-safe programming on single variables. In essence, the classes in this package extend the notion of volatile values, fields, and array elements to those that also provide an atomic conditional update operation of the form:

boolean compareAndSet(expectedValue, updateValue);

The atomic classes are built around the atomic compareAndSet(...) function that maps to an atomic CPU instruction. The atomic classes introduce the happen-before ordering as the volatile variables do. (with one exception: weakCompareAndSet(...)).

From the java docs:

When a thread sees an update to an atomic variable caused by a weakCompareAndSet, it does not necessarily see updates to any other variables that occurred before the weakCompareAndSet.

To your question:

Does this mean that whosoever takes lock on it, that will be setting its value first. And in if meantime, some other thread comes up and read old value while first thread was changing its value, then doesn't new thread will read its old value?

You don't lock anything, what you are describing is a typical race condition that will happen eventually if threads access shared data without proper synchronization. As already mentioned declaring a variable volatile in this case will only ensure that other threads will see the change of the variable (the value will not be cached in a register of some cache that is only seen by one thread).

What is the difference between AtomicInteger and volatile int?

AtomicInteger provides atomic operations on an int with proper synchronization (eg. incrementAndGet(), getAndAdd(...), ...), volatile int will just ensure the visibility of the int to other threads.

There is a minlength property in the HTML5 specification now, as well as the validity.tooShort interface.

Both are now enabled in recent versions of all modern browsers. For details, see https://caniuse.com/#search=minlength.

With SQL Server 2005, I would use this:

select replace(convert(char(10),getdate(),102),'.',' ')

Results: 2015 03 05

Gathering solutions from multiple places here on StackOverflow, I think the next one sums it up:

If you don't need the keyboard to be shown anywhere on your activity, you can simply use the next flags which are used for dialogs (got from here) :

    getWindow().setFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM, WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);

If you don't want it only for a specific EditText, you can use this (got from here) :

public static boolean disableKeyboardForEditText(@NonNull EditText editText) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        editText.setShowSoftInputOnFocus(false);
        return true;
    }
    if (Build.VERSION.SDK_INT > Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1)
        try {
            final Method method = EditText.class.getMethod("setShowSoftInputOnFocus", new Class[]{boolean.class});
            method.setAccessible(true);
            method.invoke(editText, false);
            return true;
        } catch (Exception ignored) {
        }
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2)
        try {
            Method method = TextView.class.getMethod("setSoftInputShownOnFocus", boolean.class);
            method.setAccessible(true);
            method.invoke(editText, false);
            return true;
        } catch (Exception ignored) {
        }
    return false;
}

Or this (taken from here) :

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
           editText.setShowSoftInputOnFocus(false);
       else
           editText.setTextIsSelectable(true); 

You can't call it asynchronously, since there is no asynchronous property support, only async methods. As such, there are two options, both taking advantage of the fact that asynchronous methods in the CTP are really just a method that returns Task<T> or Task:

// Make the property return a Task<T>
public Task<IEnumerable> MyList
{
    get
    {
         // Just call the method
         return MyAsyncMethod();
    }
}

Or:

// Make the property blocking
public IEnumerable MyList
{
    get
    {
         // Block via .Result
         return MyAsyncMethod().Result;
    }
}

Other Way is:

String[] parts = selectedFilePath.split("/");
    final String fileName = parts[parts.length-1];

the best method I could suggest is this

1. Download the wheel file from this location for your version of python

   • https://pypi.python.org/pypi/scipy

2. Move the file to your Main Drive eg C:>

3. Run Cmd and enter the following

   • pip install scipy-1.0.0rc1-cp36-none-win_amd64.whl

Please note this is the version I am using for my pyhton 3.6.2 it should install fine

you may want to run this command after to make sure all your python add ons are up to date

pip list --outdated

You can't set a favicon from CSS - if you want to do this explicitly you have to do it in the markup as you described.

Most browsers will, however, look for a favicon.ico file on the root of the web site - so if you access http://example.com most browsers will look for http://example.com/favicon.ico automatically.

You can also do like this

$arr_view_data['var1'] = $value1;
$arr_view_data['var2'] = $value2;
$arr_view_data['var3'] = $value3;

return view('your_viewname_here',$arr_view_data);

And you access this variable to view as $var1,$var2,$var3

I am trying to parse JSON data returned from an ajax call, and the following is working for me:

Sample PHP code

$portfolio_array= Array('desc'=>'This is test description1','item1'=>'1.jpg','item2'=>'2.jpg');

echo json_encode($portfolio_array);

And in the .js, i am parsing like this:

var req=$.post("json.php", { id: "" + id + ""},
function(data) {
    data=$.parseJSON(data);
    alert(data.desc);
    $.each(data, function(i,item){
    alert(item);
    });
})
.success(function(){})
.error(function(){alert('There was problem loading portfolio details.');})
.complete(function(){});

If you have multidimensional array like below

$portfolio_array= Array('desc'=>'This is test description 1','items'=> array('item1'=>'1.jpg','item2'=>'2.jpg'));
echo json_encode($portfolio_array);

Then the code below should work:

var req=$.post("json.php", { id: "" + id + 
    function(data) {
    data=$.parseJSON(data);
    alert(data.desc);
    $.each(data.items, function(i,item){
    alert(item);
    });
})
.success(function(){})
.error(function(){alert('There was problem loading portfolio details.');})
.complete(function(){});

Please note the sub array key here is items, and suppose if you have xyz then in place of data.items use data.xyz

Rishav Rastogi is right, and with rails 3.0 or higher its:

rails generate scaffold ...

rails destroy scaffold ...

Try this:

ini_set('error_reporting', E_STRICT);

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

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

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

URI javadoc

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

You don't set the behavior of controls via CSS, only their styling.You can use jquery or simple javascript to change the property of the fields.

There is a limit, but you can split your values into separate blocks of in()

Select * 
From table 
Where Col IN (123,123,222,....)
or Col IN (456,878,888,....)

You have at least two issues in your code:

• ng-change="getScoreData(Score)

  Angular doesn't see getScoreData method that refers to defined service

• getScoreData: function (Score, callback)

  We don't need to use callback since GET returns promise. Use then instead.

Here is a working example (I used random address only for simulation):

HTML

<select ng-model="score"
        ng-change="getScoreData(score)" 
        ng-options="score as score.name for score in  scores"></select>
    <pre>{{ScoreData|json}}</pre> 

JS

var fessmodule = angular.module('myModule', ['ngResource']);

fessmodule.controller('fessCntrl', function($scope, ScoreDataService) {

    $scope.scores = [{
        name: 'Bukit Batok Street 1',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, 153 Bukit Batok Street 1&sensor=true'
    }, {
        name: 'London 8',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, London 8&sensor=true'
    }];

    $scope.getScoreData = function(score) {
        ScoreDataService.getScoreData(score).then(function(result) {
            $scope.ScoreData = result;
        }, function(result) {
            alert("Error: No data returned");
        });
    };

});

fessmodule.$inject = ['$scope', 'ScoreDataService'];

fessmodule.factory('ScoreDataService', ['$http', '$q', function($http) {

    var factory = {
        getScoreData: function(score) {
            console.log(score);
            var data = $http({
                method: 'GET',
                url: score.URL
            });


            return data;
        }
    }
    return factory;
}]);

To add to Skelly's Bootstrap 3 no-gutter answer above (https://stackoverflow.com/a/21282059/662883)

Add the following to prevent gutters on a row containing only one column (useful when using column-wrapping: http://getbootstrap.com/css/#grid-example-wrapping):

.row.no-gutter [class*='col-']:only-child,
.row.no-gutter [class*='col-']:only-child
{
    padding-right: 0;
    padding-left: 0;
}

if you have autoplay property in the iframe src it wont help to reload the src attr/prop so you have to replace the autoplay=1 to autoplay=0

  var stopVideo = function(player) {
    var vidSrc = player.prop('src').replace('autoplay=1','autoplay=0');
    player.prop('src', vidSrc);
  };

  stopVideo($('#video'));

I hope I am not overstating the obvious, but why not do it directly in the ASP side? Unless you are dynamically altering the SQL based on certain conditions in your program, you should avoid codebehind as much as possible.

You could do the above all in ASP directly without code using the SqlDataSource control and a property in your dropdownlist.

<asp:GridView ID="gvSubjects" runat="server" DataKeyNames="SubjectID" OnRowDataBound="GridView_RowDataBound" OnDataBound="GridView_DataBound">
    <Columns>
        <asp:TemplateField HeaderText="Subjects">
            <ItemTemplate>
                <asp:DropDownList ID="ddlSubjects" runat="server" DataSourceID="sdsSubjects" DataTextField="SubjectName" DataValueField="SubjectID">
                </asp:DropDownList>
                <asp:SqlDataSource ID="sdsSubjects" runat="server"
                    SelectCommand="SELECT SubjectID,SubjectName FROM Students.dbo.Subjects"></asp:SqlDataSource>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

Java convert a String to decimal:

String dennis = "0.00000008880000";
double f = Double.parseDouble(dennis);
System.out.println(f);
System.out.println(String.format("%.7f", f));
System.out.println(String.format("%.9f", new BigDecimal(f)));
System.out.println(String.format("%.35f", new BigDecimal(f)));
System.out.println(String.format("%.2f", new BigDecimal(f)));

This prints:

8.88E-8
0.0000001
0.000000089
0.00000008880000000000000106383001366
0.00

Note that Dapper object mapping isn't case sensitive, so you can name your properties like this:

public class Person 
{
    public int Person_Id { get; set; }
    public string First_Name { get; set; }
    public string Last_Name { get; set; }
}

Or keep the Person class and use a PersonMap:

  public class PersonMap 
        {
            public int Person_Id { get; set; }
            public string First_Name { get; set; }
            public string Last_Name { get; set; }
            public Person Map(){
              return new Person{
                PersonId = Person_Id,
                FirstName = First_Name,
                LastName = Last_Name
               }               
            }
        }

And then, in the query result:

var person = conn.Query<PersonMap>(sql).Select(x=>x.Map()).ToList();

Follow these links for the MSDN descriptions of:

• Math.Floor, which rounds down towards negative infinity.
• Math.Ceiling, which rounds up towards positive infinity.
• Math.Truncate, which rounds up or down towards zero.
• Math.Round, which rounds to the nearest integer or specified number of decimal places. You can specify the behavior if it's exactly equidistant between two possibilities, such as rounding so that the final digit is even ("Round(2.5,MidpointRounding.ToEven)" becoming 2) or so that it's further away from zero ("Round(2.5,MidpointRounding.AwayFromZero)" becoming 3).

The following diagram and table may help:

-3        -2        -1         0         1         2         3
 +--|------+---------+----|----+--|------+----|----+-------|-+
    a                     b       c           d            e

                       a=-2.7  b=-0.5  c=0.3  d=1.5  e=2.8
                       ======  ======  =====  =====  =====
Floor                    -3      -1      0      1      2
Ceiling                  -2       0      1      2      3
Truncate                 -2       0      0      1      2
Round (ToEven)           -3       0      0      2      3
Round (AwayFromZero)     -3      -1      0      2      3

Note that Round is a lot more powerful than it seems, simply because it can round to a specific number of decimal places. All the others round to zero decimals always. For example:

n = 3.145;
a = System.Math.Round (n, 2, MidpointRounding.ToEven);       // 3.14
b = System.Math.Round (n, 2, MidpointRounding.AwayFromZero); // 3.15

With the other functions, you have to use multiply/divide trickery to achieve the same effect:

c = System.Math.Truncate (n * 100) / 100;                    // 3.14
d = System.Math.Ceiling (n * 100) / 100;                     // 3.15

By wrapping your comparisons in {} in your first example you are creating ScriptBlocks; so the PowerShell interpreter views it as Where-Object { <ScriptBlock> -and <ScriptBlock> }. Since the -and operator operates on boolean values, PowerShell casts the ScriptBlocks to boolean values. In PowerShell anything that is not empty, zero or null is true. The statement then looks like Where-Object { $true -and $true } which is always true.

Instead of using {}, use parentheses ().

Also you want to use -eq instead of -match since match uses regex and will be true if the pattern is found anywhere in the string (try: 'xlsx' -match 'xls').

Invoke-Command -computername SERVERNAME { 
    Get-ChildItem -path E:\dfsroots\datastore2\public | 
        Where-Object {($_.extension -eq ".xls" -or $_.extension -eq ".xlk") -and ($_.creationtime -ge "06/01/2014")}
}

A better option is to filter the extensions at the Get-ChildItem command.

Invoke-Command -computername SERVERNAME { 
    Get-ChildItem -path E:\dfsroots\datastore2\public\* -Include *.xls, *.xlk | 
        Where-Object {$_.creationtime -ge "06/01/2014"}
}

This is more an add-on to the best answer above (GZip Compression can be enabled directly through IIS) which is correct if your running IIS on Windows desktop however...

If your running IIS on Windows Server, this content compression feature is found in a different place to desktop Windows (not in programs and features in Control Panel). First open "Server Manager" then click Manage -> "Add Roles & Features" then keep clicking NEXT (make sure you select the correct server when you see the list of servers if your managing multiple servers from this instance) until you get to SERVER ROLES, scroll down to and open "Web Server (IIS)..." then "Web Server" then "Performance" then tick "Dynamic Content Compression" then click INSTALL. I tested this on Server 2016 Standard so there may be slight differences if your on an earlier version of Server.

Then follow the instructions from Testing - Check if GZIP Compression is Enabled

Hope you don't mind but I cobbled together all the helpful stuff, from above, and came up with a complete class ready for testing...

You can escape the "space" char by putting a \ right before it.

The .BAK files from SQL server are in Microsoft Tape Format (MTF) ref: http://www.fpns.net/willy/msbackup.htm

The bak file will probably contain the LDF and MDF files that SQL server uses to store the database.

You will need to use SQL server to extract these. SQL Server Express is free and will do the job.

So, install SQL Server Express edition, and open the SQL Server Powershell. There execute sqlcmd -S <COMPUTERNAME>\SQLExpress (whilst logged in as administrator)

then issue the following command.

restore filelistonly from disk='c:\temp\mydbName-2009-09-29-v10.bak';
GO

This will list the contents of the backup - what you need is the first fields that tell you the logical names - one will be the actual database and the other the log file.

RESTORE DATABASE mydbName FROM disk='c:\temp\mydbName-2009-09-29-v10.bak'
WITH 
   MOVE 'mydbName' TO 'c:\temp\mydbName_data.mdf', 
   MOVE 'mydbName_log' TO 'c:\temp\mydbName_data.ldf';
GO

At this point you have extracted the database - then install Microsoft's "Sql Web Data Administrator". together with this export tool and you will have an SQL script that contains the database.

var datos = $("#id_formulario").serialize();
$.ajax({         
    url: "url.php",

    dataType: "html",                 
    data: datos,                 
    success: function (prueba) { 
        alert("funciona!");
    }//FIN SUCCES

});//FIN  AJAX

    def addDay(date, number):

            #try to add a day
            try:
                date = date.replace(day = date.day + 1)
            #in case it's impossible ex:january 32nd add a month and restart at day 1
            except:
                #add month part
                try:
                    date = date.replace(month = date.month +1, day = 1)
                except:
                    date = date.replace(year = date.year +1, month = 1, day = 1)

Try to change z-index value for .modal and .modal-backdrop less than .datepicker z-index value.

2020 now.

Simple add this to PageAdapter:

override fun getItemPosition(`object`: Any): Int {
    return PagerAdapter.POSITION_NONE
}

For me this single line solution works very well

Correct syntax:

[System.Runtime.InteropServices.RuntimeEnvironment]::GetSystemVersion()
#or
$PSVersionTable.CLRVersion

The GetSystemVersion function returns a string like this:

v2.0.50727        #PowerShell v2.0 in Win 7 SP1

or like this

v4.0.30319        #PowerShell v3.0 (Windows Management Framework 3.0) in Win 7 SP1

$PSVersionTable is a read-only object. The CLRVersion property is a structured version number like this:

Major  Minor  Build  Revision
-----  -----  -----  --------
4      0      30319  18444   

Standard Subversion layout

Create a git clone of that includes your Subversion trunk, tags, and branches with

git svn clone http://svn.example.com/project -T trunk -b branches -t tags

The --stdlayout option is a nice shortcut if your Subversion repository uses the typical structure:

git svn clone http://svn.example.com/project --stdlayout

Make your git repository ignore everything the subversion repo does:

git svn show-ignore >> .git/info/exclude

You should now be able to see all the Subversion branches on the git side:

git branch -r

Say the name of the branch in Subversion is waldo. On the git side, you'd run

git checkout -b waldo-svn remotes/waldo

The -svn suffix is to avoid warnings of the form

warning: refname 'waldo' is ambiguous.

To update the git branch waldo-svn, run

git checkout waldo-svn
git svn rebase

Starting from a trunk-only checkout

To add a Subversion branch to a trunk-only clone, modify your git repository's .git/config to contain

[svn-remote "svn-mybranch"]
        url = http://svn.example.com/project/branches/mybranch
        fetch = :refs/remotes/mybranch

You'll need to develop the habit of running

git svn fetch --fetch-all

to update all of what git svn thinks are separate remotes. At this point, you can create and track branches as above. For example, to create a git branch that corresponds to mybranch, run

git checkout -b mybranch-svn remotes/mybranch

For the branches from which you intend to git svn dcommit, keep their histories linear!

Further information

You may also be interested in reading an answer to a related question.

SELECT *, COUNT(*) FROM my_table is not what you want, and it's not really valid SQL, you have to group by all the columns that's not an aggregate.

You'd want something like

SELECT somecolumn,someothercolumn, COUNT(*) 
   FROM my_table 
GROUP BY somecolumn,someothercolumn

Something like this should do the trick (However, read after the snippet for more info)

CREATE PROCEDURE GetFilteredData()
BEGIN
  DECLARE bDone INT;

  DECLARE var1 CHAR(16);    -- or approriate type
  DECLARE Var2 INT;
  DECLARE Var3 VARCHAR(50);

  DECLARE curs CURSOR FOR  SELECT something FROM somewhere WHERE some stuff;
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET bDone = 1;

  DROP TEMPORARY TABLE IF EXISTS tblResults;
  CREATE TEMPORARY TABLE IF NOT EXISTS tblResults  (
    --Fld1 type,
    --Fld2 type,
    --...
  );

  OPEN curs;

  SET bDone = 0;
  REPEAT
    FETCH curs INTO var1,, b;

    IF whatever_filtering_desired
       -- here for whatever_transformation_may_be_desired
       INSERT INTO tblResults VALUES (var1, var2, var3 ...);
    END IF;
  UNTIL bDone END REPEAT;

  CLOSE curs;
  SELECT * FROM tblResults;
END

A few things to consider...

Concerning the snippet above:

• may want to pass part of the query to the Stored Procedure, maybe particularly the search criteria, to make it more generic.
• If this method is to be called by multiple sessions etc. may want to pass a Session ID of sort to create a unique temporary table name (actually unnecessary concern since different sessions do not share the same temporary file namespace; see comment by Gruber, below)
• A few parts such as the variable declarations, the SELECT query etc. need to be properly specified

More generally: trying to avoid needing a cursor.

I purposely named the cursor variable curs[e], because cursors are a mixed blessing. They can help us implement complicated business rules that may be difficult to express in the declarative form of SQL, but it then brings us to use the procedural (imperative) form of SQL, which is a general feature of SQL which is neither very friendly/expressive, programming-wise, and often less efficient performance-wise.

Maybe you can look into expressing the transformation and filtering desired in the context of a "plain" (declarative) SQL query.

If someone finds this question like me, here are my performance tests of proposed methods:

Python 2.7.8

In [1]: %timeit ([1]*1000000).insert(0, 0)
100 loops, best of 3: 4.62 ms per loop

In [2]: %timeit ([1]*1000000)[0:0] = [0]
100 loops, best of 3: 4.55 ms per loop

In [3]: %timeit [0] + [1]*1000000
100 loops, best of 3: 8.04 ms per loop

As you can see, insert and slice assignment are as almost twice as fast than explicit adding and are very close in results. As Raymond Hettinger noted insert is more common option and I, personally prefer this way to prepend to list.

How about this:

private static byte[] xor(final byte[] input, final byte[] secret) {
    final byte[] output = new byte[input.length];
    if (secret.length == 0) {
        throw new IllegalArgumentException("empty security key");
    }
    int spos = 0;
    for (int pos = 0; pos < input.length; ++pos) {
        output[pos] = (byte) (input[pos] ^ secret[spos]);
        ++spos;
        if (spos >= secret.length) {
            spos = 0;
        }
    }
    return output;
}

Works fine for me and is rather compact.

Note that it may be better use subdomains instead of usual URL. So, set .example.com instead of https://example.com/.

Thanks to Jody Jacobus Geers and others I wrote so:

if (savedInstanceState == null) {
    val cookieManager = CookieManager.getInstance()
    cookieManager.acceptCookie()
    val domain = ".example.com"
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        cookieManager.setCookie(domain, "token=$token") {
            view.webView.loadUrl(url)
        }
        cookieManager.setAcceptThirdPartyCookies(view.webView, true)
    } else {
        cookieManager.setCookie(domain, "token=$token")
        view.webView.loadUrl(url)
    }
} else {
    // Check whether we're recreating a previously destroyed instance.
    view.webView.restoreState(savedInstanceState)
}

In many cases, you have an interface and pass along an object that implements it. Dialogs for example have the OnClickListener.

Just as a random example:

// The callback interface
interface MyCallback {
    void callbackCall();
}

// The class that takes the callback
class Worker {
   MyCallback callback;

   void onEvent() {
      callback.callbackCall();
   }
}

// Option 1:

class Callback implements MyCallback {
   void callbackCall() {
      // callback code goes here
   }
}

worker.callback = new Callback();

// Option 2:

worker.callback = new MyCallback() {

   void callbackCall() {
      // callback code goes here
   }
};

I probably messed up the syntax in option 2. It's early.

You can directly plot the lines you want by feeding the plot command with the corresponding data (boundaries of the segments):

plot([x1, x2], [y1, y2], color='k', linestyle='-', linewidth=2)

(of course you can choose the color, line width, line style, etc.)

From your example:

import numpy as np
import matplotlib.pyplot as plt

np.random.seed(5)
x = np.arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
plt.plot(x, y, "o")


# draw vertical line from (70,100) to (70, 250)
plt.plot([70, 70], [100, 250], 'k-', lw=2)

# draw diagonal line from (70, 90) to (90, 200)
plt.plot([70, 90], [90, 200], 'k-')

plt.show()

Something like:

select t1.name, t2.image_id, t3.path
from table1 t1 inner join table2 t2 on t1.person_id = t2.person_id
inner join table3 t3 on t2.image_id=t3.image_id

class Program
{
    double[] a = new double[] { 1, 3, 4, 8, 21, 38 };
    double[] b = new double[] { 1, 7, 19, 3, 2, 24 };
    double[] result;


    public double[] CheckSorting()
    {
        for(int i = 1; i < a.Length; i++)
        {
            if (a[i] < a[i - 1])
                result = b;
            else
                result = a;
        }
        return result;
    }

    static void Main(string[] args)
    {
        Program checkSorting = new Program();
        checkSorting.CheckSorting();
        Console.ReadLine();
    }
}

This should work, otherwise i got the error that not all codepaths return a value. Therefor i set the result as the returned value, which is set as either B or A depending on which is true

Like this:

$result1 = mysql_query($query1);
$result2 = mysql_query($query2);

// do something with the 2 result sets...

if ($result1)
    mysql_free_result($result1);

if ($result2)
    mysql_free_result($result2);

From my experience, the way I do it is create a snapshot of your current image, then once its done you'll see it as an option when launching new instances. Simply launch it as a large instance at that point.

This is my approach if I do not want any downtime(i.e. production server) because this solution only takes a server offline only after the new one is up and running(I also use it to add new machines to my clusters by using this approach to only add new machines). If Downtime is acceptable then see Marcel Castilho's answer.

If anyone else simply wants to display a black image as a background, here e.g. for 500x500 px:

cv2.imshow("Simple_black", black_screen)
cv2.waitKey(0)

In addition, if you wish to parse your object in case of http error (400-5** codes), You can use the following code: (just replace 'getInputStream' with 'getErrorStream':

    BufferedReader rd = new BufferedReader(
            new InputStreamReader(conn.getErrorStream()));
    StringBuilder sb = new StringBuilder();
    String line;
    while ((line = rd.readLine()) != null) {
        sb.append(line);
    }
    rd.close();
    return sb.toString();

            res.push(m)
        }
    }
    return res;
}

You may reply 10%, and let's assume that's right.

Now, what if I say that the random person is a man and is 15 years old?

You may say 15 or 20%, but why?.

In fact, we try to update our initial guess with new pieces of evidence ( P(smoker) vs. P(smoker | evidence) ). The Bayes rule is a way to relate these two probabilities.

P(smoker | evidence) = P(smoker)* p(evidence | smoker)/P(evidence)

Each evidence may increase or decrease this chance. For example, this fact that he is a man may increase the chance provided that this percentage (being a man) among non-smokers is lower.

In the other words, being a man must be an indicator of being a smoker rather than a non-smoker. Therefore, if an evidence is an indicator of something, it increases the chance.

But how do we know that this is an indicator?

For each feature, you can compare the commonness (probability) of that feature under the given conditions with its commonness alone. (P(f | x) vs. P(f)).

P(smoker | evidence) / P(smoker) = P(evidence | smoker)/P(evidence)

For example, if we know that 90% of smokers are men, it's not still enough to say whether being a man is an indicator of being smoker or not. For example if the probability of being a man in the society is also 90%, then knowing that someone is a man doesn't help us ((90% / 90%) = 1. But if men contribute to 40% of the society, but 90% of the smokers, then knowing that someone is a man increases the chance of being a smoker (90% / 40%) = 2.25, so it increases the initial guess (10%) by 2.25 resulting 22.5%.

However, if the probability of being a man was 95% in the society, then regardless of the fact that the percentage of men among smokers is high (90%)! the evidence that someone is a man decreases the chance of him being a smoker! (90% / 95%) = 0.95).

So we have:

P(smoker | f1, f2, f3,... ) = P(smoker) * contribution of f1* contribution of f2 *... 
=
P(smoker)* 
(P(being a man | smoker)/P(being a man))*
(P(under 20 | smoker)/ P(under 20))

Note that in this formula we assumed that being a man and being under 20 are independent features so we multiplied them, it means that knowing that someone is under 20 has no effect on guessing that he is man or woman. But it may not be true, for example maybe most adolescence in a society are men...

To use this formula in a classifier

The classifier is given with some features (being a man and being under 20) and it must decide if he is an smoker or not (these are two classes). It uses the above formula to calculate the probability of each class under the evidence (features), and it assigns the class with the highest probability to the input. To provide the required probabilities (90%, 10%, 80%...) it uses the training set. For example, it counts the people in the training set that are smokers and find they contribute 10% of the sample. Then for smokers checks how many of them are men or women .... how many are above 20 or under 20....In the other words, it tries to build the probability distribution of the features for each class based on the training data.

It sounds like what you're asking about involves serializing the data structure of a Django model instance for interoperability. The other posters are correct: if you wanted the serialized form to be used with a python application that can query the database via Django's api, then you would wan to serialize a queryset with one object. If, on the other hand, what you need is a way to re-inflate the model instance somewhere else without touching the database or without using Django, then you have a little bit of work to do.

Here's what I do:

First, I use demjson for the conversion. It happened to be what I found first, but it might not be the best. My implementation depends on one of its features, but there should be similar ways with other converters.

Second, implement a json_equivalent method on all models that you might need serialized. This is a magic method for demjson, but it's probably something you're going to want to think about no matter what implementation you choose. The idea is that you return an object that is directly convertible to json (i.e. an array or dictionary). If you really want to do this automatically:

def json_equivalent(self):
    dictionary = {}
    for field in self._meta.get_all_field_names()
        dictionary[field] = self.__getattribute__(field)
    return dictionary

This will not be helpful to you unless you have a completely flat data structure (no ForeignKeys, only numbers and strings in the database, etc.). Otherwise, you should seriously think about the right way to implement this method.

Third, call demjson.JSON.encode(instance) and you have what you want.

First: it can be done without HTML5 Canvas or SVG.
Actually, someone just managed to generate client-side PNG files using JavaScript, without canvas or SVG, using the data URI scheme.

Second: you might actually not need Canvas, SVG or any of the above at all.
If you only need to process images on the client side, without modifying them, all this is not needed.

You can get the source address from the img tag on the page, make an XHR request for it - it will most probably come from the browser cache - and process it as a byte stream from Javascript.
You will need a good understanding of the image format. (The above generator is partially based on libpng sources and might provide a good starting point.)

What i have done and it works is create an instance in the MainActivity and getter for that instance:

 public class MainActivity extends AbstractMainActivity {
    private static MainActivity mInstanceActivity;
    public static MainActivity getmInstanceActivity() {
    return mInstanceActivity;
    }

And the in the onCreate method just point to that activity:

@Override
protected void onCreate(Bundle savedInstanceState) {
mInstanceActivity = this;
}

And in onDestroy you should set this instance to null:

@Override
protected void onDestroy() {
    super.onDestroy();
    mInstanceActivity = null;
}

Later you can call every method in whatever class you want:

MainActivity.getmInstanceActivity().yourMethod();

Change AND to OR. Simple mistake. Think of it like plain English, I want to select anything with that equals this or that.

I suggest that you give an if to the div than:

$("#my_div_id").html();

Finally, I got a solution for reloading page once after two months research.

It works fine on my clientside JS project.

I wrote a function that below reloading page only once.

1) First getting browser domloading time

2) Get current timestamp

3) Browser domloading time + 10 seconds

4) If Browser domloading time + 10 seconds bigger than current now timestamp then page is able to be refreshed via "reloadPage();"

But if it's not bigger than 10 seconds that means page is just reloaded thus It will not be reloaded repeatedly.

5) Therefore if you call "reloadPage();" function in somewhere in your js file page will only be reloaded once.

Hope that helps somebody

// Reload Page Function //
                function reloadPage() {
                    var currentDocumentTimestamp = new Date(performance.timing.domLoading).getTime();
                    // Current Time //
                    var now = Date.now();
                    // Total Process Lenght as Minutes //
                    var tenSec = 10 * 1000;
                    // End Time of Process //
                    var plusTenSec = currentDocumentTimestamp + tenSec;
                    if (now > plusTenSec) {
                        location.reload();
                    }
                }


                // You can call it in somewhere //
                reloadPage();

You could loop through the list and keep the tuple in a variable and then you can see both values from the same variable...

num=(0, 0)
for item in tuplelist:
  if item[1]>num[1]:
    num=item #num has the whole tuple with the highest y value and its x value

The code condition ? statement_A : statement_B is equivalent to

if condition == true
  statement_A
else
  statement_B
end

Mistake in original post is acquire() call set inside the try loop. Here is a correct approach to use "binary" semaphore (Mutex):

semaphore.acquire();
try {
   //do stuff
} catch (Exception e) {
   //exception stuff
} finally {
   semaphore.release();
}

The performant function Python provides for this is set.issubset. It does have a few restrictions that make it unclear if it's the answer to your question, however.

A list may contain items multiple times and has a specific order. A set does not. Additionally, sets only work on hashable objects.

Are you asking about subset or subsequence (which means you'll want a string search algorithm)? Will either of the lists be the same for many tests? What are the datatypes contained in the list? And for that matter, does it need to be a list?

Your other post intersect a dict and list made the types clearer and did get a recommendation to use dictionary key views for their set-like functionality. In that case it was known to work because dictionary keys behave like a set (so much so that before we had sets in Python we used dictionaries). One wonders how the issue got less specific in three hours.

See comment in: https://github.com/Microsoft/TypeScript/issues/3069#issuecomment-99964139

TypeScript does not come with built in pollyfills. it is up to you to decide which pollyfill to use, if any. you can use something like es6Collection, es6-shims, corejs..etc. All the Typescript compiler needs is a declaration for the ES6 constructs you want to use. you can find them all in this lib file.

here is the relevant portion:

interface Map<K, V> {
    clear(): void;
    delete(key: K): boolean;
    entries(): IterableIterator<[K, V]>;
    forEach(callbackfn: (value: V, index: K, map: Map<K, V>) => void, thisArg?: any): void;
    get(key: K): V;
    has(key: K): boolean;
    keys(): IterableIterator<K>;
    set(key: K, value?: V): Map<K, V>;
    size: number;
    values(): IterableIterator<V>;
    [Symbol.iterator]():IterableIterator<[K,V]>;
    [Symbol.toStringTag]: string;
}

interface MapConstructor {
    new <K, V>(): Map<K, V>;
    new <K, V>(iterable: Iterable<[K, V]>): Map<K, V>;
    prototype: Map<any, any>;
}
declare var Map: MapConstructor;

If you want the word "Hello" to print in a column that's 40 characters wide, with spaces padding the left, use the following.

char *ptr = "Hello";
printf("%40s\n", ptr);

That will give you 35 spaces, then the word "Hello". This is how you format stuff when you know how wide you want the column, but the data changes (well, it's one way you can do it).

If you know you want exactly 40 spaces then some text, just save the 40 spaces in a constant and print them. If you need to print multiple lines, either use multiple printf statements like the one above, or do it in a loop, changing the value of ptr each time.

DECIMAL(18,0) will allow 0 digits after the decimal point.

Use something like DECIMAL(18,4) instead that should do just fine!

That gives you a total of 18 digits, 4 of which after the decimal point (and 14 before the decimal point).

For my case, the above answers did not work. I was checking for a string in an array and assigning it to a boolean value. I modified @Anton Gogolev's answer and removed the Any() method and put the stringToCheck inside the Contains() method.

bool = stringArray.Contains(stringToCheck);

Well I think firstly keep whole main into try catch(or you can use as public static void main(String arg[]) throws IOException ) and then also use full path of file in which you are writing as

PrintWriter printWriter = new PrintWriter ("C:/Users/Me/Desktop/directory/file.txt");

all those directies like users,Me,Desktop,directory should be user made. java wont make directories own its own. it should be as

import java.io.*;
public class PrintWriterClass {

public static void main(String arg[]) throws IOException{
    PrintWriter pw = new PrintWriter("C:/Users/Me/Desktop/directory/file.txt");
    pw.println("hiiiiiii");
    pw.close();
}   

}

It also counts the days and convert them in months.

function monthDiff(d1, d2) {
    var months;
    months = (d2.getFullYear() - d1.getFullYear()) * 12;   //calculates months between two years
    months -= d1.getMonth() + 1; 
    months += d2.getMonth();  //calculates number of complete months between two months
    day1 = 30-d1.getDate();  
    day2 = day1 + d2.getDate();
    months += parseInt(day2/30);  //calculates no of complete months lie between two dates
    return months <= 0 ? 0 : months;
}

monthDiff(
    new Date(2017, 8, 8), // Aug 8th, 2017    (d1)
    new Date(2017, 12, 12)  // Dec 12th, 2017   (d2)
);
//return value will be 4 months 

I made an update of the actual answer.

This seems to be working on firefox and chrome: http://jsfiddle.net/gatsbimantico/QJeB7/1/embedded/result/

.x{
columns: 5em;
-webkit-columns: 5em; /* Safari and Chrome */
-moz-columns: 5em; /* Firefox */
}
.x li{
    float:left;
    break-inside: avoid-column;
    -webkit-column-break-inside: avoid;  /* Safari and Chrome */
}

Note: The float property seems to be the one making the block behaviour.

Quick and dirty fix

class MyData:
    def __init__(string=None,list=None):
        if string is not None:
            #do stuff
        elif list is not None:
            #do other stuff
        else:
            #make data empty

Then you can call it with

MyData(astring)
MyData(None, alist)
MyData()

Use the system stored procedure sp_who2.

The match between .val('Bruce jones') and value="Bruce Jones" is case-sensitive. It looks like you're capitalizing Jones in one but not the other. Either track down where the difference comes from, use id's instead of the name, or call .toLowerCase() on both.

Try this example and you will understand also what is the difference between Associative Array and Object in JavaScript.

Associative Array

var a = new Array(1,2,3); 
a['key'] = 'experiment';
Array.isArray(a);

returns true

Keep in mind that a.length will be undefined, because length is treated as a key, you should use Object.keys(a).length to get the length of an Associative Array.

Object

var a = {1:1, 2:2, 3:3,'key':'experiment'}; 
Array.isArray(a)

returns false

JSON returns an Object ... could return an Associative Array ... but it is not like that

Just try to do this one (through root access) - "chmod -R 777 /home/username/git"

Here is another method I devised, in this case using | instead of & :

bool is_power_of_2(ulong x) {
    if(x ==  (1 << (sizeof(ulong)*8 -1) ) return true;
    return (x > 0) && (x<<1 == (x|(x-1)) +1));
}

You shouldn't use both ngRoute and UI-router. Here's a sample code for UI-router:

repoApp.config(function($stateProvider, $urlRouterProvider) {_x000D_
  _x000D_
  $stateProvider_x000D_
    .state('state1', {_x000D_
      url: "/state1",_x000D_
      templateUrl: "partials/state1.html",_x000D_
      controller: 'YourCtrl'_x000D_
    })_x000D_
    _x000D_
    .state('state2', {_x000D_
      url: "/state2",_x000D_
      templateUrl: "partials/state2.html",_x000D_
      controller: 'YourOtherCtrl'_x000D_
    });_x000D_
    $urlRouterProvider.otherwise("/state1");_x000D_
});_x000D_
//etc.

You can find a great answer on the difference between these two in this thread: What is the difference between angular-route and angular-ui-router?

You can also consult UI-Router's docs here: https://github.com/angular-ui/ui-router

You can use std::make_pair

revenue.push_back(std::make_pair("string",map[i].second));

I agree with some comments about NOLOCK hint and especially with those saying "use it when it's appropriate". If the application written poorly and is using concurrency inappropriate way – that may cause the lock escalation. Highly transactional table also are getting locked all the time due to their nature. Having good index coverage won't help with retrieving the data, but setting ISOLATION LEVEL to READ UNCOMMITTED does. Also I believe that using NOLOCK hint is safe in many cases when the nature of changes is predictable. For example – in manufacturing when jobs with travellers are going through different processes with lots of inserts of measurements, you can safely execute query against the finished job with NOLOCK hint and this way avoid collision with other sessions that put PROMOTED or EXCLUSIVE locks on the table/page. The data you access in this case is static, but it may reside in a very transactional table with hundreds of millions of records and thousands updates/inserts per minute. Cheers

When you use a decorator, you're replacing one function with another. In other words, if you have a decorator

def logged(func):
    def with_logging(*args, **kwargs):
        print(func.__name__ + " was called")
        return func(*args, **kwargs)
    return with_logging

then when you say

@logged
def f(x):
   """does some math"""
   return x + x * x

it's exactly the same as saying

def f(x):
    """does some math"""
    return x + x * x
f = logged(f)

and your function f is replaced with the function with_logging. Unfortunately, this means that if you then say

print(f.__name__)

it will print with_logging because that's the name of your new function. In fact, if you look at the docstring for f, it will be blank because with_logging has no docstring, and so the docstring you wrote won't be there anymore. Also, if you look at the pydoc result for that function, it won't be listed as taking one argument x; instead it'll be listed as taking *args and **kwargs because that's what with_logging takes.

If using a decorator always meant losing this information about a function, it would be a serious problem. That's why we have functools.wraps. This takes a function used in a decorator and adds the functionality of copying over the function name, docstring, arguments list, etc. And since wraps is itself a decorator, the following code does the correct thing:

from functools import wraps
def logged(func):
    @wraps(func)
    def with_logging(*args, **kwargs):
        print(func.__name__ + " was called")
        return func(*args, **kwargs)
    return with_logging

@logged
def f(x):
   """does some math"""
   return x + x * x

print(f.__name__)  # prints 'f'
print(f.__doc__)   # prints 'does some math'

select max(Emp_Sal) 
from Employee a
where 1 = ( select count(*) 
         from Employee b
         where b.Emp_Sal > a.Emp_Sal)

Yes running man.

Modern browsers support the "viewport height" unit. This will expand the div to the available viewport height. I find it more reliable than any other approach.

#some_div {
    height: 100vh;
    background: black;
}

Update: The script is now located on github.

I wrote a small python script, that leverages scapy's arping().

If you're putting this in a string within a program, you may actually need to use four backslashes (because the string parser will remove two of them when "de-escaping" it for the string, and then the regex needs two for an escaped regex backslash).

For instance:

regex("\\\\")

is interpreted as...

regex("\\" [escaped backslash] followed by "\\" [escaped backslash])

is interpreted as...

regex(\\)

is interpreted as a regex that matches a single backslash.

Depending on the language, you might be able to use a different form of quoting that doesn't parse escape sequences to avoid having to use as many - for instance, in Python:

re.compile(r'\\')

The r in front of the quotes makes it a raw string which doesn't parse backslash escapes.

That's the way I use it:

global.ts

export var server: string = 'http://localhost:4200/';
export var var2: number = 2;
export var var3: string = 'var3';

to use it just import like that:

import { Injectable } from '@angular/core';
import { Http, Headers, RequestOptions } from '@angular/http';
import { Observable } from 'rxjs/Rx';
import * as glob from '../shared/global'; //<== HERE

@Injectable()
export class AuthService {
    private AuhtorizationServer = glob.server
}

AutopostBack is a property which you assign to web controls if you want to post back the page when any event occurs at them.

You may see this article: What is AutoPostBack?

Autopostback is the mechanism, by which the page will be posted back to the server automatically based on some events in the web controls. In some of the web controls, the property called auto post back, which if set to true, will send the request to the server when an event happens in the control

For example, TextBox has AutoPostBack property

Use the AutoPostBack property to specify whether an automatic postback to the server will occur when the TextBox control loses focus. Pressing the ENTER or the TAB key while in the TextBox control is the most common way to change focus.

Run the script as source= to run in debug mode as well.

source= ./myscript.sh

You can use VARRAY for a fixed-size array:

declare
   type array_t is varray(3) of varchar2(10);
   array array_t := array_t('Matt', 'Joanne', 'Robert');
begin
   for i in 1..array.count loop
       dbms_output.put_line(array(i));
   end loop;
end;

Or TABLE for an unbounded array:

...
   type array_t is table of varchar2(10);
...

The word "table" here has nothing to do with database tables, confusingly. Both methods create in-memory arrays.

With either of these you need to both initialise and extend the collection before adding elements:

declare
   type array_t is varray(3) of varchar2(10);
   array array_t := array_t(); -- Initialise it
begin
   for i in 1..3 loop
      array.extend(); -- Extend it
      array(i) := 'x';
   end loop;
end;

The first index is 1 not 0.

If you run jupyter in the background like me:

jupyter notebook &> /dev/null &

Then to exit jupyter completely, instead of Ctl-C, make an alias command:

echo 'alias quitjupyter="kill $(pgrep jupyter)"' >> ~/.bashrc

Restart your terminal. Kill all jupyter instances:

quitjupyter

Note: use double quotes inside of single quotes as shown above. The other way around will evaluate the expression before writing it to your .bashrc (you want to write the command itself not 'kill 1430' or whatever process number may be associated with a current jupyter instance). Of course you can use any alias you wish. I actually use 'qjup':

echo 'alias qjup="kill $(pgrep jupyter)"' >> ~/.bashrc

Restart your terminal. Kill all jupyter instances:

qjup

For latest socket.io version use

socket.request.connection.remoteAddress

For example:

var socket = io.listen(server);
socket.on('connection', function (client) {
  var client_ip_address = socket.request.connection.remoteAddress;
}

beware that the code below returns the Server's IP, not the Client's IP

var address = socket.handshake.address;
console.log('New connection from ' + address.address + ':' + address.port);

If you happen to be using jQuery, you might want to give this a shot: http://api.jquery.com/category/deferred-object/

It allows you to defer the execution of your callback function until the ajax request (or any async operation) is completed. This can also be used to call a callback once several ajax requests have all completed.

Just for kicks

mse = (np.linalg.norm(A-B)**2)/len(A)

You might find it easier to understand by using a simple subquery

SELECT `settings`.*, (
    SELECT `value` FROM `character_settings`
    WHERE `character_settings`.`setting_id` = `settings`.`id`
      AND `character_settings`.`character_id` = '1') AS cv_value
FROM `settings`

The subquery is allowed to return null, so you don't have to worry about JOIN/WHERE in the main query.

Sometimes, this works faster in MySQL, but compare it against the LEFT JOIN form to see what works best for you.

SELECT s.*, c.value
FROM settings s
LEFT JOIN character_settings c ON c.setting_id = s.id AND c.character_id = '1'

Laravel Collection implements the PHP ArrayAccess interface (which is why using foreach is possible in the first place).

If you have the key already you can just use PHP unset.

I prefer this, because it clearly modifies the collection in place, and is easy to remember.

foreach ($collection as $key => $value) {
    unset($collection[$key]);
}

Using case

#!/bin/bash

fun1 () {
    echo "run function1"
    [[ "$@" ]] && echo "options: $@"
}

fun2 () {
    echo "run function2"
    [[ "$@" ]] && echo "options: $@"
}

case $1 in
    fun1) "$@"; exit;;
    fun2) "$@"; exit;;
esac

fun1
fun2

This script will run functions fun1 and fun2 but if you start it with option fun1 or fun2 it'll only run given function with args(if provided) and exit. Usage

$ ./test 
run function1
run function2

$ ./test fun2 a b c
run function2
options: a b c

ALTER TABLE `table_name` AUTO_INCREMENT=1

EXECUTE IMMEDIATE 'insert into MY_TBL (Col) values(''ER0002'')'; worked for me. closing the varchar/string with two pairs of single quotes did the trick. Other option could be to use using keyword, EXECUTE IMMEDIATE 'insert into MY_TBL (Col) values(:text_string)' using 'ER0002'; Remember using keyword will not work, if you are using EXECUTE IMMEDIATE to execute DDL's with parameters, however, using quotes will work for DDL's.

  DateFormat dateFormat = new SimpleDateFormat("MMMM dd yyyy");
  java.util.Date date = new java.util.Date();
  System.out.println("Current Date : " + dateFormat.format(date));

Another option is the SimpleXML extension (I believe it comes standard with most php installs.)

http://php.net/manual/en/book.simplexml.php

The syntax looks something like this for your example

$xml = new SimpleXMLElement($xmlString);
echo $xml->bbb->cccc->dddd['Id'];
echo $xml->bbb->cccc->eeee['name'];
// or...........
foreach ($xml->bbb->cccc as $element) {
  foreach($element as $key => $val) {
   echo "{$key}: {$val}";
  }
}

You can do it like this as well,

let copiedData = JSON.parse(JSON.stringify(data));

The whole key is whether you're doing an idempotent change or not. That is, if taking action on the message twice will result in “the same” thing being there as if it was only done once, you've got an idempotent change and it should be mapped to PUT. If not, it maps to POST. If you never permit the client to synthesize URLs, PUT is pretty close to Update and POST can handle Create just fine, but that's most certainly not the only way to do it; if the client knows that it wants to create /foo/abc and knows what content to put there, it works just fine as a PUT.

The canonical description of a POST is when you're committing to purchasing something: that's an action which nobody wants to repeat without knowing it. By contrast, setting the dispatch address for the order beforehand can be done with PUT just fine: it doesn't matter if you are told to send to 6 Anywhere Dr, Nowhereville once, twice or a hundred times: it's still the same address. Does that mean that it's an update? Could be… It all depends on how you want to write the back-end. (Note that the results might not be identical: you could report back to the user when they last did a PUT as part of the representation of the resource, which would ensure that repeated PUTs do not cause an identical result, but the result would still be “the same” in a functional sense.)

You could iterate on a copy (clone) of your original list:

List<String> copy = new ArrayList<String>(list);
for (String s : copy) {
    // And if you have to add an element to the list, add it to the original one:
    list.add("some element");
}

Note that it is not even possible to add a new element to a list while iterating on it, because it will result in a ConcurrentModificationException.

Run this command in your project console:

mvn idea:idea

Done. Had this issue many times. Tried 'Invalidate Cache & Restart' and all other solutions. Running that command works perfect to me. I'm currently using IntelliJ 2019.2, but this also happened in previous versions and solution worked as well.

this works fine, but file name does not display anymore.

$(document).ready(function(){ $("img.attach2").click(function(){ $("input.attach1").click(); return false; }); });

This is a start, I don't think it works exactly as you intend, but it at least produces a consistent result.

import java.io.File;

public class Main
{
    public static void main(final String[] argv)
        throws Exception
    {
        System.out.println(pathJoin());
        System.out.println(pathJoin(""));
        System.out.println(pathJoin("a"));
        System.out.println(pathJoin("a", "b"));
        System.out.println(pathJoin("a", "b", "c"));
        System.out.println(pathJoin("a", "b", "", "def"));
    }

    public static String pathJoin(final String ... pathElements)
    {
        final String path;

        if(pathElements == null || pathElements.length == 0)
        {
            path = File.separator;
        }
        else
        {
            final StringBuilder builder;

            builder = new StringBuilder();

            for(final String pathElement : pathElements)
            {
                final String sanitizedPathElement;

                // the "\\" is for Windows... you will need to come up with the 
                // appropriate regex for this to be portable
                sanitizedPathElement = pathElement.replaceAll("\\" + File.separator, "");

                if(sanitizedPathElement.length() > 0)
                {
                    builder.append(sanitizedPathElement);
                    builder.append(File.separator);
                }
            }

            path = builder.toString();
        }

        return (path);
    }
}

This may be a long shot, but Crystal Reports for Eclipse is free. I'm not sure if it will work, but if all you need is to edit some static text, you could get that version of CR and get the job done.

As simple as that

  private static byte[] getByteArrayFromByteBuffer(ByteBuffer byteBuffer) {
    byte[] bytesArray = new byte[byteBuffer.remaining()];
    byteBuffer.get(bytesArray, 0, bytesArray.length);
    return bytesArray;
}

When using buildout I have following in .gitignore (along with *.pyo and *.pyc):

.installed.cfg
bin
develop-eggs
dist
downloads
eggs
parts
src/*.egg-info
lib
lib64

Thanks to Jacob Kaplan-Moss

Also I tend to put .svn in since we use several SCM-s where I work.

You can also use this variant with text strings, here's the complete changed code (Code from Mikael), tested in C# 2012:

// Variable
string MessageBoxTitle = "Some Title";
string MessageBoxContent = "Sure";

DialogResult dialogResult = MessageBox.Show(MessageBoxContent, MessageBoxTitle, MessageBoxButtons.YesNo);
if(dialogResult == DialogResult.Yes)
{
    //do something
}
else if (dialogResult == DialogResult.No)
{
    //do something else
}

You can after

.YesNo

insert a message icon

, MessageBoxIcon.Question

Enter the formula =ROW() into any cell and that cell will show the row number as its value.

If you want 1001, 1002 etc just enter =1000+ROW()

Starting in Numpy 1.20, the sliding_window_view provides a way to slide/roll through windows of elements. Windows that you can then individually average.

For instance, for a 4-element window:

from numpy.lib.stride_tricks import sliding_window_view

# values = np.array([5, 3, 8, 10, 2, 1, 5, 1, 0, 2])
np.average(sliding_window_view(values, window_shape = 4), axis=1)
# array([6.5, 5.75, 5.25, 4.5, 2.25, 1.75, 2])

Note the intermediary result of sliding_window_view:

# values = np.array([5, 3, 8, 10, 2, 1, 5, 1, 0, 2])
sliding_window_view(values, window_shape = 4)
# array([[ 5,  3,  8, 10],
#        [ 3,  8, 10,  2],
#        [ 8, 10,  2,  1],
#        [10,  2,  1,  5],
#        [ 2,  1,  5,  1],
#        [ 1,  5,  1,  0],
#        [ 5,  1,  0,  2]])

You should design your table WITHOUT considering the views.
Apart from saving joins and conditions, Views do have a performance advantage: SQL Server may calculate and save its execution plan in the view, and therefore make it faster than "on the fly" SQL statements.
View may also ease your work regarding user access at field level.

You can use pydoc.

Open your terminal and type python -m pydoc list.append

The advantage of pydoc over help() is that you do not have to import a module to look at its help text. For instance python -m pydoc random.randint.

Also you can start an HTTP server to interactively browse documentation by typing python -m pydoc -b (python 3)

For more information python -m pydoc

Actually, with strings, you can do something like this:

oldStr = 'Hello World!'    
newStr = ''

for i in oldStr:  
    if 'a' < i < 'z':    
        newStr += chr(ord(i)-32)     
    else:      
        newStr += i
print(newStr)

'HELLO WORLD!'

Basically, I'm "adding"+"strings" together into a new string :).

if you can write a batch file that does not need to be interactive, try running that batch file as a service, to do what needs to be done.

check this condition

String string="//some string...//"

check this... if(string.equals((string.reverse()) { it is palindrome }

I actually found a better way to send files using HttpURLConnection using MultipartEntity

private static String multipost(String urlString, MultipartEntity reqEntity) {
    try {
        URL url = new URL(urlString);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setReadTimeout(10000);
        conn.setConnectTimeout(15000);
        conn.setRequestMethod("POST");
        conn.setUseCaches(false);
        conn.setDoInput(true);
        conn.setDoOutput(true);

        conn.setRequestProperty("Connection", "Keep-Alive");
        conn.addRequestProperty("Content-length", reqEntity.getContentLength()+"");
        conn.addRequestProperty(reqEntity.getContentType().getName(), reqEntity.getContentType().getValue());

        OutputStream os = conn.getOutputStream();
        reqEntity.writeTo(conn.getOutputStream());
        os.close();
        conn.connect();

        if (conn.getResponseCode() == HttpURLConnection.HTTP_OK) {
            return readStream(conn.getInputStream());
        }

    } catch (Exception e) {
        Log.e(TAG, "multipart post error " + e + "(" + urlString + ")");
    }
    return null;        
}

private static String readStream(InputStream in) {
    BufferedReader reader = null;
    StringBuilder builder = new StringBuilder();
    try {
        reader = new BufferedReader(new InputStreamReader(in));
        String line = "";
        while ((line = reader.readLine()) != null) {
            builder.append(line);
        }
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (reader != null) {
            try {
                reader.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
    return builder.toString();
} 

Assuming you are uploading an image with bitmap data:

    Bitmap bitmap = ...;
    String filename = "filename.png";
    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, bos);
    ContentBody contentPart = new ByteArrayBody(bos.toByteArray(), filename);

    MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
    reqEntity.addPart("picture", contentPart);
    String response = multipost("http://server.com", reqEntity);

And Voila! Your post data will contain picture field along with the filename and path on your server.

There are two additional ways to do it apart from the two methods mentioned in @PradeepJain's answer.

I would suggest not to use this approach and to fall back to this only as a last resort if you are not using [(ngModel)] directive and also not using data binding via [value]. Read this for more info.

Using ElementRef

app.component.html

<div>
      <input type="text" #searchInput placeholder="Search...">
      <button (click)="clearSearchInput()">Clear</button>
</div>

app.component.ts

export class App {
  @ViewChild('searchInput') searchInput: ElementRef;

  clearSearchInput(){
     this.searchInput.nativeElement.value = '';
  }
}

Using FormGroup

app.component.html

<form [formGroup]="form">
    <div *ngIf="first.invalid"> Name is too short. </div>
    <input formControlName="first" placeholder="First name">
    <input formControlName="last" placeholder="Last name">
    <button type="submit">Submit</button>
</form>
<button (click)="setValue()">Set preset value</button>
<button (click)="clearInputMethod1()">Clear Input Method 1</button>
<button (click)="clearInputMethod2()">Clear Input Method 2</button>

app.component.ts

export class AppComponent {
  form = new FormGroup({
    first: new FormControl('Nancy', Validators.minLength(2)),
    last: new FormControl('Drew'),
  });
  get first(): any { return this.form.get('first'); }
  get last(): any { return this.form.get('last'); }
  clearInputMethod1() { this.first.reset(); this.last.reset(); }
  clearInputMethod2() { this.form.setValue({first: '', last: ''}); }
  setValue() { this.form.setValue({first: 'Nancy', last: 'Drew'}); }
}

See if the BSD C Standard Library has fcvt(). You could start with the source for it that rather than writing your code from scratch. The UNIX 98 standard fcvt() apparently does not output scientific notation so you would have to implement it yourself, but I don't think it would be hard.

Use OpenFileDialog.SafeFileName

OpenFileDialog.SafeFileName Gets the file name and extension for the file selected in the dialog box. The file name does not include the path.

If you are using posix sed

Selection for any case for a pattern (converting the searched pattern with this sed than use the converted pattern in you wanted command using regex:

echo "${MyOrgPattern} | sed "s/[aA]/[aA]/g;s/[bB]/[bB]/g;s/[cC]/[cC]/g;s/[dD]/[dD]/g;s/[eE]/[eE]/g;s/[fF]/[fF]/g;s/[gG]/[gG]/g;s/[hH]/[hH]/g;s/[iI]/[iI]/g;s/[jJ]/[jJ]/g;s/[kK]/[kK]/g;s/[lL]/[lL]/g;s/[mM]/[mM]/g;s/[nN]/[nN]/g;s/[oO]/[oO]/g;s/[pP]/[pP]/g;s/[qQ]/[qQ]/g;s/[rR]/[rR]/g;s/[sS]/[sS]/g;s/[tT]/[tT]/g;s/[uU]/[uU]/g;s/[vV]/[vV]/g;s/[wW]/[wW]/g;s/[xX]/[xX]/g;s/[yY]/[yY]/g;s/[zZ]/[zZ]/g" | read -c MyNewPattern
 YourInputStreamCommand | egrep "${MyNewPattern}"

convert in lower case

sed "s/[aA]/a/g;s/[bB]/b/g;s/[cC]/c/g;s/[dD]/d/g;s/[eE]/e/g;s/[fF]/f/g;s/[gG]/g/g;s/[hH]/h/g;s/[iI]/i/g;s/j/[jJ]/g;s/[kK]/k/g;s/[lL]/l/g;s/[mM]/m/g;s/[nN]/n/g;s/[oO]/o/g;s/[pP]/p/g;s/[qQ]/q/g;s/[rR]/r/g;s/[sS]/s/g;s/[tT]/t/g;s/[uU]/u/g;s/[vV]/v/g;s/[wW]/w/g;s/[xX]/x/g;s/[yY]/y/g;s/[zZ]/z/g"

same for uppercase replace lower letter between // by upper equivalent in the sed

Have fun

With the latest Python extension for Visual Studio Code, there is a venvPath Setting:

// Path to folder with a list of Virtual Environments (e.g. ~/.pyenv, ~/Envs, ~/.virtualenvs).
  "python.venvPath": "",

On Mac OS X, go to Code ? Preferences ? Settings and scroll down to Python Configuration.

Look for "python.venvPath: "", and click the pencil on the left-hand side to open up your user settings. Finally, add the path to where you store your virtual environments.

If you are using virtuanenvwrapper, or you have put all your virtual environment setting in one folder, this will be the one for you.

After you have configured "python.venvPath", restart Visual Studio Code. Then open the command palette and look for "Python: Select Interpreter". At this point, you should see the interpreter associated with the virtual environment you just added.

Another great way to accomplish this is to use a transparent image with a set aspect ratio. Then set the width of the image to 100% and the height to auto. That unfortunately will push down the original content of the container. So you need to wrap the original content in another div and position it absolutely to the top of the parent div.

<div class="parent">
   <img class="aspect-ratio" src="images/aspect-ratio.png" />
   <div class="content">Content</div>
</div>

CSS

.parent {
  position: relative;
}
.aspect-ratio {
  width: 100%;
  height: auto;
}
.content {
  position: absolute;
  width: 100%;
  top: 0; left: 0;
}

from bs4 import BeautifulSoup
from selenium import webdriver

driver = webdriver.Chrome()
html_source_code = driver.execute_script("return document.body.innerHTML;")
html_soup: BeautifulSoup = BeautifulSoup(html_source_code, 'html.parser')

Now you can apply BeautifulSoup function to extract data...

The only solution that worked for me and $.each was definitely causing the error. so i used for loop and it's not throwing error anymore.

Example code

     $.ajax({
            type: 'GET',
            url: 'https://example.com/api',
            data: { get_param: 'value' },
            success: function (data) {
                for (var i = 0; i < data.length; ++i) {
                    console.log(data[i].NameGerman);
                }
            }
        });

I have tried opening the .gitignore file in my vscode, windows 10. There you can see, some previously added ignore files (if any).

To create a new rule to ignore a file with (.js) extension, append the extension of the file like this:

*.js

This will ignore all .js files in your git repository.

To exclude certain type of file from a particular directory, you can add this:

**/foo/*.js

This will ignore all .js files inside only /foo/ directory.

For a detailed learning you can visit: about git-ignore

If the variable ax.xaxis._autolabelpos = True, matplotlib sets the label position in function _update_label_position in axis.py according to (some excerpts):

    bboxes, bboxes2 = self._get_tick_bboxes(ticks_to_draw, renderer)
    bbox = mtransforms.Bbox.union(bboxes)
    bottom = bbox.y0
    x, y = self.label.get_position()
    self.label.set_position((x, bottom - self.labelpad * self.figure.dpi / 72.0))

You can set the label position independently of the ticks by using:

    ax.xaxis.set_label_coords(x0, y0)

that sets _autolabelpos to False or as mentioned above by changing the labelpad parameter.

use this URL : "https://twitter.com/(userName)/profile_image?size=original"

If you are using TWitter SDK you can get the user name when logged in, with TWTRAPIClient, using TWTRAuthSession.

This is the code snipe for iOS:

if let twitterId = session.userID{
   let twitterClient = TWTRAPIClient(userID: twitterId)
   twitterClient.loadUser(withID: twitterId) {(user, error) in
       if let userName = user?.screenName{
          let url = "https://twitter.com/\(userName)/profile_image?size=original")
       }
   }
}

Although it can be done in one scan but to correct your own code , you must declare largest2 as int.Min as it prevents the largest2 holding the largest value intially.

To improve James' excellent answer:

It's better to put BINARY in front of the constant instead:

SELECT * FROM `table` WHERE `column` = BINARY 'value'

Putting BINARY in front of column will prevent the use of any index on that column.

def all_anagrams(words: [str]) -> [str]:
    word_dict = {}
    for word in words:
        sorted_word  = "".join(sorted(word))
        if sorted_word in word_dict:
            word_dict[sorted_word].append(word)
        else:
            word_dict[sorted_word] = [word]
    return list(word_dict.values())  

You can increase the capacity of the stack by the following :

import sys
sys.setrecursionlimit(10000)

This problem may occur if you have two devices connected to the computer at the same time. Adb does not support reaching both devices via command/console. So, if you debug your app after connecting and disconnecting the second device you will most probably have this problem. One solution might be restarting adb and/or eclipse if necessary. It can be quite annoying sometimes and I am afraid there is no other solution to that.

If you try set a value in datetime-local

date("Y-m-d\TH:i",strtotime('2010-12-30 23:21:46'));

//output : 2010-12-30T23:21

One interesting difference :

lst=[1]
print lst          // prints [1]
print type(lst)    // prints <type 'list'>

notATuple=(1)
print notATuple        // prints 1
print type(notATuple)  // prints <type 'int'>
                                         ^^ instead of tuple(expected)

A comma must be included in a tuple even if it contains only a single value. e.g. (1,) instead of (1).

Input:

4546644645

Code:

PhoneNumber = Input.replace(/(\d\d\d)(\d\d\d)(\d\d\d\d)/, "($1)$2-$3");

It Depends how much functionality you are expecting by Excel<->Acess solution. In many cases where you don't have budget to get a complete application solution, these little utilities does work. If the Scope of project is limited then I would go for this solution, because excel does give you flexibility to design spreadsheets as in accordance to your needs and then you may use those predesigned sheets for users to use. Designing a spreadsheet like form in Access is more time consuming and difficult and does requires some ActiveX. It object might not only handling data but presenting in spreadsheet like formates then this solution should works with limited scope.

Here is yet another solution using JavaScript. Specialities of my solution:

• Handles null values as infinity
• Assumes that the lower bound is inclusive and the upper bound exclusive.
• Comes with a bunch of tests

The tests are based on integers but since date objects in JavaScript are comparable you can just throw in two date objects as well. Or you could throw in the millisecond timestamp.

Code:

/**
 * Compares to comparable objects to find out whether they overlap.
 * It is assumed that the interval is in the format [from,to) (read: from is inclusive, to is exclusive).
 * A null value is interpreted as infinity
 */
function intervalsOverlap(from1, to1, from2, to2) {
    return (to2 === null || from1 < to2) && (to1 === null || to1 > from2);
}

Tests:

describe('', function() {
    function generateTest(firstRange, secondRange, expected) {
        it(JSON.stringify(firstRange) + ' and ' + JSON.stringify(secondRange), function() {
            expect(intervalsOverlap(firstRange[0], firstRange[1], secondRange[0], secondRange[1])).toBe(expected);
        });
    }

    describe('no overlap (touching ends)', function() {
        generateTest([10,20], [20,30], false);
        generateTest([20,30], [10,20], false);

        generateTest([10,20], [20,null], false);
        generateTest([20,null], [10,20], false);

        generateTest([null,20], [20,30], false);
        generateTest([20,30], [null,20], false);
    });

    describe('do overlap (one end overlaps)', function() {
        generateTest([10,20], [19,30], true);
        generateTest([19,30], [10,20], true);

        generateTest([10,20], [null,30], true);
        generateTest([10,20], [19,null], true);
        generateTest([null,30], [10,20], true);
        generateTest([19,null], [10,20], true);
    });

    describe('do overlap (one range included in other range)', function() {
        generateTest([10,40], [20,30], true);
        generateTest([20,30], [10,40], true);

        generateTest([10,40], [null,null], true);
        generateTest([null,null], [10,40], true);
    });

    describe('do overlap (both ranges equal)', function() {
        generateTest([10,20], [10,20], true);

        generateTest([null,20], [null,20], true);
        generateTest([10,null], [10,null], true);
        generateTest([null,null], [null,null], true);
    });
});

I think using Object.toString() for any purpose other than debugging is probably a really bad idea, even though in this case the two are functionally equivalent (assuming the list has no nulls). Developers are free to change the behavior of any toString() method without any warning, including the toString() methods of any classes in the standard library.

Don't even worry about the performance problems caused by the boxing/unboxing process. If performance is critical, just use an array. If it's really critical, don't use Java. Trying to outsmart the JVM will only lead to heartache.

Simple, use static.

In activity you have the method you want to call:

private static String name = "Robert";

...

public static String getData() {
    return name;
}

And in your activity where you make the call:

private static String name;

...

name = SplashActivity.getData();

Here's the Javadoc in Oracle's website for the Date class: https://docs.oracle.com/javase/8/docs/api/java/util/Date.html
If you scroll down to "Constructor Summary," you'll see the different options for how a Date object can be instantiated. Like all objects in Java, you create a new one with the following:

Date firstDate = new Date(ConstructorArgsHere);

Now you have a bit of a choice. If you don't pass in any arguments, and just do this,

Date firstDate = new Date();

it will represent the exact date and time at which you called it. Here are some other constructors you may want to make use of:

Date firstDate1 = new Date(int year, int month, int date);
Date firstDate2 = new Date(int year, int month, int date, int hrs, int min);
Date firstDate3 = new Date(int year, int month, int date, int hrs, int min, int sec);

I needed to append substrings to create an ssh command, I solved with sprintf (Visual Studio 2013)

char gStrSshCommand[SSH_COMMAND_MAX_LEN]; // declare ssh command string

strcpy(gStrSshCommand, ""); // empty string

void appendSshCommand(const char *substring) // append substring
{
  sprintf(gStrSshCommand, "%s %s", gStrSshCommand, substring);
}

Based on an issue on Github of PhantomJS, the quit() does not terminate PhantomJS process. You should use:

import signal
driver = webdriver.PhantomJS(service_args=service_args)
# Do your work here

driver.service.process.send_signal(signal.SIGTERM)
driver.quit()

Call it like this:

foo(*ob);

Note that there is no casting going on here, as suggested in your question title. All we have done is de-referenced the pointer to the object which we then pass to the function.

Here's another C version. It defines a macro called wicked_cast() for inline type punning via C99 union literals and the non-standard __typeof__ operator.

#include <limits.h>

#if UCHAR_MAX == UINT_MAX
#error endianness irrelevant as sizeof(int) == 1
#endif

#define wicked_cast(TYPE, VALUE) \
    (((union { __typeof__(VALUE) src; TYPE dest; }){ .src = VALUE }).dest)

_Bool is_little_endian(void)
{
    return wicked_cast(unsigned char, 1u);
}

If integers are single-byte values, endianness makes no sense and a compile-time error will be generated.

Since nowadays, computers support widely any length as file type, the choice is now only personal. Back in the early days of Windows where only 3 letters where supported, you had to use .htm, but not anymore.

As Geoff says, what Crockford says is good.

The only exception I follow (and have seen widely used) is to use $varname to indicate a jQuery (or whatever library) object. E.g.

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

var $footer = $('#footer');
