Aside from the orders-of-magnitude performance advantage over heap allocation, stack allocation is preferable for long running server applications. Even the best managed heaps eventually get so fragmented that application performance degrades.

In my case this works fine...

sudo npm i -g browserslist caniuse-lite

You can just wrap the expression in a call to list:

>>> list(x for x in string.letters if x in (y for y in "BigMan on campus"))
['a', 'c', 'g', 'i', 'm', 'n', 'o', 'p', 's', 'u', 'B', 'M']

Better you update your eclipse by clicking it on help >> check for updates, also you can start eclipse by entering command in command prompt eclipse -clean.
Hope this will help you.

Event listeners

First off it's important to understand that there are two kinds of "event listeners":

1. Scope event listeners registered via $on:

   $scope.$on('anEvent', function (event, data) {
     ...
   });
   

2. Event handlers attached to elements via for example on or bind:

   element.on('click', function (event) {
     ...
   });
   

$scope.$destroy()

When $scope.$destroy() is executed it will remove all listeners registered via $on on that $scope.

It will not remove DOM elements or any attached event handlers of the second kind.

This means that calling $scope.$destroy() manually from example within a directive's link function will not remove a handler attached via for example element.on, nor the DOM element itself.

element.remove()

Note that remove is a jqLite method (or a jQuery method if jQuery is loaded before AngularjS) and is not available on a standard DOM Element Object.

When element.remove() is executed that element and all of its children will be removed from the DOM together will all event handlers attached via for example element.on.

It will not destroy the $scope associated with the element.

To make it more confusing there is also a jQuery event called $destroy. Sometimes when working with third-party jQuery libraries that remove elements, or if you remove them manually, you might need to perform clean up when that happens:

element.on('$destroy', function () {
  scope.$destroy();
});

What to do when a directive is "destroyed"

This depends on how the directive is "destroyed".

A normal case is that a directive is destroyed because ng-view changes the current view. When this happens the ng-view directive will destroy the associated $scope, sever all the references to its parent scope and call remove() on the element.

This means that if that view contains a directive with this in its link function when it's destroyed by ng-view:

scope.$on('anEvent', function () {
 ...
});

element.on('click', function () {
 ...
});

Both event listeners will be removed automatically.

However, it's important to note that the code inside these listeners can still cause memory leaks, for example if you have achieved the common JS memory leak pattern circular references.

Even in this normal case of a directive getting destroyed due to a view changing there are things you might need to manually clean up.

For example if you have registered a listener on $rootScope:

var unregisterFn = $rootScope.$on('anEvent', function () {});

scope.$on('$destroy', unregisterFn);

This is needed since $rootScope is never destroyed during the lifetime of the application.

The same goes if you are using another pub/sub implementation that doesn't automatically perform the necessary cleanup when the $scope is destroyed, or if your directive passes callbacks to services.

Another situation would be to cancel $interval/$timeout:

var promise = $interval(function () {}, 1000);

scope.$on('$destroy', function () {
  $interval.cancel(promise);
});

If your directive attaches event handlers to elements for example outside the current view, you need to manually clean those up as well:

var windowClick = function () {
   ...
};

angular.element(window).on('click', windowClick);

scope.$on('$destroy', function () {
  angular.element(window).off('click', windowClick);
});

These were some examples of what to do when directives are "destroyed" by Angular, for example by ng-view or ng-if.

If you have custom directives that manage the lifecycle of DOM elements etc. it will of course get more complex.

ok. I tried the above two ways but it didnt work for me. After trial and error i came to know that actually the file was not getting saved in 'this.state.file' variable.

fileUpload = (e) => {
    let data = e.target.files
    if(e.target.files[0]!=null){
        this.props.UserAction.fileUpload(data[0], this.fallBackMethod)
    }
}

here fileUpload is a different js file which accepts two params like this

export default (file , callback) => {
const formData = new FormData();
formData.append('fileUpload', file);

return dispatch => {
    axios.put(BaseUrl.RestUrl + "ur/url", formData)
        .then(response => {
            callback(response.data);
        }).catch(error => {
         console.log("*****  "+error)
    });
}

}

don't forget to bind method in the constructor. Let me know if you need more help in this.

According to nginx documentation

there is no syntax for NOT matching a regular expression. Instead, match the target regular expression and assign an empty block, then use location / to match anything else

So you could define something like

location ~ (dir1|file2\.php) { 
    # empty
}

location / {
    rewrite ^/(.*) http://example.com/$1 permanent; 
}

This works fine for me:

var base64String = btoa(String.fromCharCode.apply(null, new Uint8Array(arrayBuffer)));

In ES6, the syntax is a little simpler:

let base64String = btoa(String.fromCharCode(...new Uint8Array(arrayBuffer)));

As pointed out in the comments, this method may result in a runtime error in some browsers when the ArrayBuffer is large. The exact size limit is implementation dependent in any case.

You need to create a CustomListAdapter.

public class CustomListAdapter extends ArrayAdapter <String> {

    private Context mContext;
    private int id;
    private List <String>items ;

    public CustomListAdapter(Context context, int textViewResourceId , List<String> list ) 
    {
        super(context, textViewResourceId, list);           
        mContext = context;
        id = textViewResourceId;
        items = list ;
    }

    @Override
    public View getView(int position, View v, ViewGroup parent)
    {
        View mView = v ;
        if(mView == null){
            LayoutInflater vi = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            mView = vi.inflate(id, null);
        }

        TextView text = (TextView) mView.findViewById(R.id.textView);

        if(items.get(position) != null )
        {
            text.setTextColor(Color.WHITE);
            text.setText(items.get(position));
            text.setBackgroundColor(Color.RED); 
            int color = Color.argb( 200, 255, 64, 64 );
                text.setBackgroundColor( color );

        }

        return mView;
    }

}

The list item looks like this (custom_list.xml):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content">
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:id="@+id/textView"
    android:textSize="20px" android:paddingTop="10dip" android:paddingBottom="10dip"/>
</LinearLayout>

Use the TextView api's to decorate your text to your liking

and you will be using it like this

listAdapter = new CustomListAdapter(YourActivity.this , R.layout.custom_list , mList);
mListView.setAdapter(listAdapter);

Use the network byte order (big endian), which is the same as Java uses anyway. See man htons for the different translators in C.

Several notes:

• s.async = true is not very correct for HTML5 doctype, correct is s.async = 'async' (actually using true is correct, thanks to amn who pointed it out in the comment just below)
• Using timeouts to control the order is not very good and safe, and you also make the loading time much larger, to equal the sum of all timeouts!

Since there is a recent reason to load files asynchronously, but in order, I'd recommend a bit more functional-driven way over your example (remove console.log for production use :) ):

(function() {
    var prot = ("https:"===document.location.protocol?"https://":"http://");

    var scripts = [
        "path/to/first.js",
        "path/to/second.js",
        "path/to/third.js"
    ];

    function completed() { console.log('completed'); }  // FIXME: remove logs

    function checkStateAndCall(path, callback) {
        var _success = false;
        return function() {
            if (!_success && (!this.readyState || (this.readyState == 'complete'))) {
                _success = true;
                console.log(path, 'is ready'); // FIXME: remove logs
                callback();
            }
        };
    }

    function asyncLoadScripts(files) {
        function loadNext() { // chain element
            if (!files.length) completed();
            var path = files.shift();
            var scriptElm = document.createElement('script');
            scriptElm.type = 'text/javascript';
            scriptElm.async = true;
            scriptElm.src = prot+path;
            scriptElm.onload = scriptElm.onreadystatechange = \
                checkStateAndCall(path, loadNext); // load next file in chain when
                                                   // this one will be ready 
            var headElm = document.head || document.getElementsByTagName('head')[0];
            headElm.appendChild(scriptElm);
        }
        loadNext(); // start a chain
    }

    asyncLoadScripts(scripts);
})();

The $.ajax() function returns a XMLHttpRequest object. Store that in a variable that's accessible from the Submit button's "OnClick" event. When a submit click is processed check to see if the XMLHttpRequest variable is:

1) null, meaning that no request has been sent yet

2) that the readyState value is 4 (Loaded). This means that the request has been sent and returned successfully.

In either of those cases, return true and allow the submit to continue. Otherwise return false to block the submit and give the user some indication of why their submit didn't work. :)

Consider the following query:

$iId = mysql_real_escape_string("1 OR 1=1");    
$sSql = "SELECT * FROM table WHERE id = $iId";

mysql_real_escape_string() will not protect you against this. The fact that you use single quotes (' ') around your variables inside your query is what protects you against this. The following is also an option:

$iId = (int)"1 OR 1=1";
$sSql = "SELECT * FROM table WHERE id = $iId";

I stumbled upon this thread while trying to find an answer to the same question the OP had. I didn't find the answer I wanted, but I ended up doing this.

public static class MyConsole
{
    public static void WriteLine(this ConsoleColor Color, string Text)
    {
        Console.ForegroundColor = Color;
        Console.WriteLine(Text);   
    }
}

And I use it like this:

ConsoleColor.Cyan.WriteLine("voilà");

f=imread(...);

h=fspecial('average', [3 3]);
g= imfilter(f, h);
imshow(g);

I have used redux-form and formik in the past, and recently React introduced Hook, and i have built a custom hook for it. Please check it out and see if it make your form validation much easier.

Github: https://github.com/bluebill1049/react-hook-form

Website: http://react-hook-form.now.sh

with this approach, you are no longer doing controlled input too.

example below:

import React from 'react'
import useForm from 'react-hook-form'

function App() {
  const { register, handleSubmit, errors } = useForm() // initialise the hook
  const onSubmit = (data) => { console.log(data) } // callback when validation pass

  return (
    <form onSubmit={handleSubmit(onSubmit)}>
      <input name="firstname" ref={register} /> {/* register an input */}

      <input name="lastname" ref={register({ required: true })} /> {/* apply required validation */}
      {errors.lastname && 'Last name is required.'} {/* error message */}

      <input name="age" ref={register({ pattern: /\d+/ })} /> {/* apply a Refex validation */}
      {errors.age && 'Please enter number for age.'} {/* error message */}

      <input type="submit" />
    </form>
  )
}

Why don't you just use a singleton?

import android.content.Context;


public class ClassicSingleton {
    private Context c=null;
    private static ClassicSingleton instance = null;
    protected ClassicSingleton()
    {
       // Exists only to defeat instantiation.
    }
    public void setContext(Context ctx)
    {
    c=ctx;
    }
    public Context getContext()
    {
       return c;
    }
    public static ClassicSingleton getInstance()
    {
        if(instance == null) {
            instance = new ClassicSingleton();
        }
        return instance;
    }
}

Then in the activity class:

 private ClassicSingleton cs = ClassicSingleton.getInstance();

And in the non activity class:

ClassicSingleton cs= ClassicSingleton.getInstance();
        Context c=cs.getContext();
        ImageView imageView = (ImageView) ((Activity)c).findViewById(R.id.imageView1);

why don't you go the simple way like

    IF EXISTS(SELECT * FROM sys.procedures WHERE NAME LIKE 'uspBlackListGetAll')
    BEGIN
         DROP PROCEDURE uspBlackListGetAll
    END
    GO

    CREATE Procedure uspBlackListGetAll

..........

turn on display errors in your ini

This will turn off interrupts and put the CPU into (permanent until reset/power toggled) sleep:

If using WORD for mac enable 'use maths autocorrect rules outside maths regions' Type \therefore

It's not working because the entire for loop (from the for to the final closing parenthesis, including the commands between those) is being evaluated when it's encountered, before it begins executing.

In other words, %count% is replaced with its value 1 before running the loop.

What you need is something like:

setlocal enableextensions enabledelayedexpansion
set /a count = 1
for /f "tokens=*" %%a in (config.properties) do (
  set /a count += 1
  echo !count!
)
endlocal

Delayed expansion using ! instead of % will give you the expected behaviour. See also here.

Also keep in mind that setlocal/endlocal actually limit scope of things changed inside so that they don't leak out. If you want to use count after the endlocal, you have to use a "trick" made possible by the very problem you're having:

endlocal && set count=%count%

Let's say count has become 7 within the inner scope. Because the entire command is interpreted before execution, it effectively becomes:

endlocal && set count=7

Then, when it's executed, the inner scope is closed off, returning count to it's original value. But, since the setting of count to seven happens in the outer scope, it's effectively leaking the information you need.

You can string together multiple sub-commands to leak as much information as you need:

endlocal && set count=%count% && set something_else=%something_else%

HTTPS requires an initial handshake which can be very slow. The actual amount of data transferred as part of the handshake isn't huge (under 5 kB typically), but for very small requests, this can be quite a bit of overhead. However, once the handshake is done, a very fast form of symmetric encryption is used, so the overhead there is minimal. Bottom line: making lots of short requests over HTTPS will be quite a bit slower than HTTP, but if you transfer a lot of data in a single request, the difference will be insignificant.

However, keepalive is the default behaviour in HTTP/1.1, so you will do a single handshake and then lots of requests over the same connection. This makes a significant difference for HTTPS. You should probably profile your site (as others have suggested) to make sure, but I suspect that the performance difference will not be noticeable.

reading through this 6yrs later and thought I'd also take a hack at it, also in the TIMTOWTDI vein...:D, hoping it isn't incorrect 'JS etiquette'.

I usually set up a var with the condition and then refer to it later on..i.e;

// var set up globally OR locally depending on your requirements
var hC;

function(el) {
  var $this = el;
  hC = $this.hasClass("test");

  // use the variable in the conditional statement
  if (!hC) {
    //
  }
}

Although I should mention that I do this because I mainly use the conditional ternary operator and want clean code. So in this case, all i'd have is this:

hC ? '' : foo(x, n) ;
   // OR -----------
!hC ? foo(x, n) : '' ;

...instead of this:

$this.hasClass("test") ? '' : foo(x, n) ;
   // OR -----------
(!$this.hasClass("test")) ? foo(x, n) : '' ;

cout << "Player" << i ;

this one is pretty good and it also works in angular 2

$("#modal .close").click()

Need to convert the the key from hex to dec before base64_encoding and then send it for handshake.

$hashedKey = sha1($key. "258EAFA5-E914-47DA-95CA-C5AB0DC85B11",true);

$rawToken = "";
    for ($i = 0; $i < 20; $i++) {
      $rawToken .= chr(hexdec(substr($hashedKey,$i*2, 2)));
    }
$handshakeToken = base64_encode($rawToken) . "\r\n";

$handshakeResponse = "HTTP/1.1 101 Switching Protocols\r\nUpgrade: websocket\r\nConnection: Upgrade\r\nSec-WebSocket-Accept: $handshakeToken\r\n";

If you want to get the first element whose id is 1 while object is being searched, you can use this function:

function customFilter(object){
    if(object.hasOwnProperty('id') && object["id"] == 1)
        return object;

    for(var i=0; i<Object.keys(object).length; i++){
        if(typeof object[Object.keys(object)[i]] == "object"){
            var o = customFilter(object[Object.keys(object)[i]]);
            if(o != null)
                return o;
        }
    }

    return null;
}

If you want to get all elements whose id is 1, then (all elements whose id is 1 are stored in result as you see):

function customFilter(object, result){
    if(object.hasOwnProperty('id') && object.id == 1)
        result.push(object);

    for(var i=0; i<Object.keys(object).length; i++){
        if(typeof object[Object.keys(object)[i]] == "object"){
            customFilter(object[Object.keys(object)[i]], result);
        }
    }
}

It was talked about it a lot already, u can find even on Wiki the reasons...

• C/C++ for the game engine and all intensive stuff.
• Lua or Python for scripting in the game.
• Java - very-very bad performance, big memory usage + it's not available on Game Consoles(It is used for some very simple games(Yes, Runescape counts in here, it's not Battlefield or Crysis or what else is there) just because there are a lot of programmers that know this programming language).
• C# - big memory usage(It is used for some very simple games just because there are pretty much programmers that know this programming language).

And I hear more and more Java programmers that try to convince people that Java is not slow, it is not slow for drawing a widget on the screen and drawing some ASCII characters on the widget, to receive and send data through network(And it is recommended to use it in this cases(network data manipulation) instead of C/C++)... But it is damn slow when it comes to serious stuff like math calculations, memory allocation/manipulation and a lot of this good stuff.

I remember an article on MIT site where they show what C/C++ can do if u use the language and compiler features: A matrix multiplier(2 matrices), 1 implementation in Java and 1 implementation in C/C++, with C/C++ features and appropriate compiler optimisations activated, the C/C++ implementation was ~296 260 times faster than the Java implementation.

I hope you understand now why people use C/C++ instead of Java in games, imagine Crysis in Java, there would not be any computer in this world which could handle that... + Garbage collection works ok for Widgets which just destroyed an image but it's still cached in there and needs to be cleaned but not for games, for sure, u will have even more lags on every garbage collection activation.

Edit: Because somebody asked for the article, here, I searched in the web archive to get that, I hope you are satisfied...MIT Case Study

And to add, no, Java for gaming is still an awful idea. Just a few days ago a big company that I will not name started rewriting their game client from Java to C++ because a very simple game(In terms of Graphics) was lagging and heating i7 Laptops with powerful nVidia GT 5xx and 6xx generation video cards(not only nVidia, the point here is that this powerful cards that can handle on Max settings most of the new games and can't handle this game) and the memory consumption was ~2.5 - 2.6 GB Ram. For such simple graphics it needs a beast of a machine.

They are not managed, but measured and possibly limited (see getrlimit system call, also on getrlimit(2)).

RSS means resident set size (the part of your virtual address space sitting in RAM).

You can query the virtual address space of process 1234 using proc(5) with cat /proc/1234/maps and its status (including memory consumption) thru cat /proc/1234/status

Add a <div> wrapper around the table, and apply the following CSS

border-radius: x px;
overflow: hidden;
display: inline-block;

to this wrapper.

In case you're using TortoiseSVN and the file is already commited, go to your files project folder, right click on the file/folder you want to ignore, TortoiseSVN -> Unversion and add to ignore list. Then you delete the folder/file (click on it and then push DELETE on your keyboard), right click on your project folder, -> SVN Commit... This will delete the folder from the repository.... Now you can create your folder/file again and then it will be ignored.

Read the documentation.

http://www.postgresql.org/docs/9.1/static/functions-datetime.html

I used a query like that:

WHERE
(
    date_trunc('day',table1.date_eval) = '2015-02-09'
)

or

WHERE(date_trunc('day',table1.date_eval) >='2015-02-09'AND date_trunc('day',table1.date_eval) <'2015-02-09')

As mention one above (@andrew) , creating custom SeekBar is super Easy with this site - http://android-holo-colors.com/

Just enable SeekBar there, choose color, and receive all resources and copy to project. Then apply them in xml, for example:

  android:thumb="@drawable/apptheme_scrubber_control_selector_holo_light"
  android:progressDrawable="@drawable/apptheme_scrubber_progress_horizontal_holo_light"

It's worth noting that if you want to sort particular properties descending, you don't want to simply append .reverse() at the end, as this will make all of the sorts descending.

To make particular sorts descending, chain your sorts from least significant to most significant, calling .reverse() after each sort that you want to be descending.

var data = _(data).chain()
    .sort("date")
    .reverse()    // sort by date descending
    .sort("name") // sort by name ascending
    .result()

Since _'s sort is a stable sort, you can safely chain and reverse sorts because if two items have the same value for a property, their order is preserved.

I found this maven repo where you could download from directly a zip file containing all the jars you need.

• https://maven.springframework.org/release/org/springframework/spring/
• https://repo.spring.io/release/org/springframework/spring/

Alternate solution: Maven

The solution I prefer is using Maven, it is easy and you don't have to download each jar alone. You can do it with the following steps:

1. Create an empty folder anywhere with any name you prefer, for example spring-source

2. Create a new file named pom.xml

3. Copy the xml below into this file

4. Open the spring-source folder in your console

5. Run mvn install

6. After download finished, you'll find spring jars in /spring-source/target/dependencies

Also, if you need to download any other spring project, just copy the dependency configuration from its corresponding web page.

For example, if you want to download Spring Web Flow jars, go to its web page, and add its dependency configuration to the pom.xml dependencies, then run mvn install again.

<dependency>
  <groupId>org.springframework.webflow</groupId>
  <artifactId>spring-webflow</artifactId>
  <version>2.3.2.RELEASE</version>

In my case, none of the code above with bundle-operate works; Here is my decision (I don't know if it is proper code or not, but it works in my case):

public class DialogMessageType extends DialogFragment {
    private static String bodyText;

    public static DialogMessageType addSomeString(String temp){
        DialogMessageType f = new DialogMessageType();
        bodyText = temp;
        return f;
    };

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        final String[] choiseArray = {"sms", "email"};
        String title = "Send text via:";
        final AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle(title).setItems(choiseArray, itemClickListener);
        builder.setCancelable(true);
        return builder.create();
    }

    DialogInterface.OnClickListener itemClickListener = new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            switch (which){
                case 0:
                    prepareToSendCoordsViaSMS(bodyText);
                    dialog.dismiss();
                    break;
                case 1:
                    prepareToSendCoordsViaEmail(bodyText);
                    dialog.dismiss();
                    break;
                default:
                    break;
            }
        }
    };
[...]
}

public class SendObjectActivity extends FragmentActivity {
[...]

DialogMessageType dialogMessageType = DialogMessageType.addSomeString(stringToSend);
dialogMessageType.show(getSupportFragmentManager(),"dialogMessageType");

[...]
}

With Java 7 a faster way to walk thru a directory tree was introduced with the Paths and Files functionality. They're much faster then the "old" File way.

This would be the code to walk thru and check path names with a regular expression:

public final void test() throws IOException, InterruptedException {
    final Path rootDir = Paths.get("path to your directory where the walk starts");

    // Walk thru mainDir directory
    Files.walkFileTree(rootDir, new FileVisitor<Path>() {
        // First (minor) speed up. Compile regular expression pattern only one time.
        private Pattern pattern = Pattern.compile("^(.*?)");

        @Override
        public FileVisitResult preVisitDirectory(Path path,
                BasicFileAttributes atts) throws IOException {

            boolean matches = pattern.matcher(path.toString()).matches();

            // TODO: Put here your business logic when matches equals true/false

            return (matches)? FileVisitResult.CONTINUE:FileVisitResult.SKIP_SUBTREE;
        }

        @Override
        public FileVisitResult visitFile(Path path, BasicFileAttributes mainAtts)
                throws IOException {

            boolean matches = pattern.matcher(path.toString()).matches();

            // TODO: Put here your business logic when matches equals true/false

            return FileVisitResult.CONTINUE;
        }

        @Override
        public FileVisitResult postVisitDirectory(Path path,
                IOException exc) throws IOException {
            // TODO Auto-generated method stub
            return FileVisitResult.CONTINUE;
        }

        @Override
        public FileVisitResult visitFileFailed(Path path, IOException exc)
                throws IOException {
            exc.printStackTrace();

            // If the root directory has failed it makes no sense to continue
            return path.equals(rootDir)? FileVisitResult.TERMINATE:FileVisitResult.CONTINUE;
        }
    });
}

Make sure Match Case is selected with Use Regular Expression so this matches. [A-Z]* If match case is not selected, this matches all letters.

Highlight both rows in the table design view and click on the key icon, they will now be a composite primary key.

I'm not sure of your question, but only one column per table may be an IDENTITY column, not both.

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

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

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

SELECT COUNT(job_id) FROM jobs WHERE posted_date < NOW()-30;

Now() returns the current Date and Time.

To support older version Space can be replaced with View as below. Add this view between after left most component and before right most component. This view with weight=1 will stretch and fill the space

    <View

        android:layout_height="20dp"
        android:layout_weight="1" />

Complete sample code is given here. It has has 4 components. Two arrows will be on the right and left side. The Text and Spinner will be in the middle.

Get-ADGroupMember "Group1" -recursive | Select-Object Name | Export-Csv c:\path\Groups.csv

I got this to work for me... I would assume that you could put "Group1, Group2, etc." or try a wildcard. I did pre-load AD into PowerShell before hand:

Get-Module -ListAvailable | Import-Module

1. When you want to store 'wide' (Unicode) characters.
2. Yes: 255 of them (excluding 0).
3. Yes.
4. Here's an introductory article: http://www.joelonsoftware.com/articles/Unicode.html

If you are running your application just on localhost and it is not yet live, I believe it is very difficult to send mail using this.

Once you put your application online, I believe that this problem should be automatically solved. By the way,ini_set() helps you to change the values in php.ini during run time.

This is the same question as Failed to connect to mailserver at "localhost" port 25

also check this php mail function not working

On the contrary, you should always prefer stack allocations, to the extent that as a rule of thumb, you should never have new/delete in your user code.

As you say, when the variable is declared on the stack, its destructor is automatically called when it goes out of scope, which is your main tool for tracking resource lifetime and avoiding leaks.

So in general, every time you need to allocate a resource, whether it's memory (by calling new), file handles, sockets or anything else, wrap it in a class where the constructor acquires the resource, and the destructor releases it. Then you can create an object of that type on the stack, and you're guaranteed that your resource gets freed when it goes out of scope. That way you don't have to track your new/delete pairs everywhere to ensure you avoid memory leaks.

The most common name for this idiom is RAII

Also look into smart pointer classes which are used to wrap the resulting pointers on the rare cases when you do have to allocate something with new outside a dedicated RAII object. You instead pass the pointer to a smart pointer, which then tracks its lifetime, for example by reference counting, and calls the destructor when the last reference goes out of scope. The standard library has std::unique_ptr for simple scope-based management, and std::shared_ptr which does reference counting to implement shared ownership.

Many tutorials demonstrate object instantiation using a snippet such as ...

So what you've discovered is that most tutorials suck. ;) Most tutorials teach you lousy C++ practices, including calling new/delete to create variables when it's not necessary, and giving you a hard time tracking lifetime of your allocations.

In your application context declare a AnnotationMethodHandlerAdapter and registerByteArrayHttpMessageConverter:

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
  <property name="messageConverters">
    <util:list>
      <bean id="byteArrayMessageConverter" class="org.springframework.http.converter.ByteArrayHttpMessageConverter"/>
    </util:list>
  </property>
</bean> 

also in the handler method set appropriate content type for your response.

I also got this error .I was using Text inside body after changing to XML(text/xml) , got result as expected.

• If your request is XML Request use XML(text/xml).

• If your request is JSON Request use JSON(application/json)

You could create a new repo with

git init 

and then use

git fetch url-to-repo branchname:refs/remotes/origin/branchname

to fetch just that one branch into a local remote-tracking branch.

I tried Ninh Pham's solution but it didn't work for me until I tweaked it - see below. Remove contentType and don't encode your json data

$.fn.postJSON = function(url, data) {
    return $.ajax({
            type: 'POST',
            url: url,
            data: data,
            dataType: 'json'
        });

I think the following would work well with lesser line of codes.

        session()->flash('toast', [
        'status' => 'success', 
        'body' => 'Body',
        'topic' => 'Success']
    );

I'm using a toaster package, but you can have something like this in your view.

             toastr.{{session('toast.status')}}(
              '{{session('toast.body')}}', 
              '{{session('toast.topic')}}'
             );

Ok, I've achieved the same thing using Bootstrap 3.0

Example with the latest bootstrap

        <div class="col-md-9 content"></div>
    </div>
</div>

The SCSS:

html, body, .wrapper {
    padding: 0;
    margin: 0;
    height: 100%;

$headerHeight: 43px;

.navigation, .content {

o(n sequre) is polynimal time complexity while o(2^n) is exponential time complexity if p=np when best case , in the worst case p=np not equal becasue when input size n grow so long or input sizer increase so longer its going to worst case and handling so complexity growth rate increase and depend on n size of input when input is small it is polynimal when input size large and large so p=np not equal it means growth rate depend on size of input "N". optimization, sat, clique, and independ set also met in exponential to polynimal.

If your app for some reason crashes without good stacktrace. Try debug it from first line, and go line by line until crash. Then you will have answer, which line is causing you trouble. Proably you could then wrapp it into try catch block and print error output.

With the Multiple SCMs Plugin:

• create a different repository entry for each repository you need to checkout (main project or dependancy project.

• for each project, in the "advanced" menu (the second "advanced" menu, there are two buttons labeled "advanced" for each repository), find the "Local subdirectory for repo (optional)" textfield. You can specify there the subdirectory in the "workspace" directory where you want to copy the project to. You could map the filesystem of my development computer.

The "second advanced menu" doesn't exist anymore, instead what needs to be done is use the "Add" button (on the "Additional Behaviours" section), and choose "Check out to a sub-directory"

• if you are using ant, as now the build.xml file with the build targets in not in the root directory of the workspace but in a subdirectory, you have to reflect that in the "Invoke Ant" configuration. To do that, in "Invoke ant", press "Advanced" and fill the "Build file" input text, including the name of the subdirectory where the build.xml is located.

Hope that helps.

A good question. Should tell you it took some time to crack this one. Here is my result.

DECLARE @TABLE TABLE
(  
ID INT,  
USERS VARCHAR(10),  
ACTIVITY VARCHAR(10),  
PAGEURL VARCHAR(10)  
)

INSERT INTO @TABLE  
VALUES  (1, 'Me', 'act1', 'ab'),
        (2, 'Me', 'act1', 'cd'),
        (3, 'You', 'act2', 'xy'),
        (4, 'You', 'act2', 'st')


SELECT T1.USERS, T1.ACTIVITY,   
        STUFF(  
        (  
        SELECT ',' + T2.PAGEURL  
        FROM @TABLE T2  
        WHERE T1.USERS = T2.USERS  
        FOR XML PATH ('')  
        ),1,1,'')  
FROM @TABLE T1  
GROUP BY T1.USERS, T1.ACTIVITY

public static void Each<T>(this IEnumerable<T> items, Action<T> action) {
foreach (var item in items) {
    action(item);
} }

... and call it thusly:

myList.Each(x => { x.Enabled = false; });

I ran into this issue and the suggested fix of rvm osx-ssl-certs update all did not work despite that I am an RVM user on OSX.

The fix that worked for me was re-installing the latest version of openssl:

brew update
brew remove openssl
brew install openssl

CASE might help you out:

SELECT t.first_name,
       t.last_name,
       t.employid,
       t.status
  FROM employeetable t
 WHERE t.status = (CASE WHEN status_flag = STATUS_ACTIVE THEN 'A'
                        WHEN status_flag = STATUS_INACTIVE THEN 'T'
                        ELSE null END)
   AND t.business_unit = (CASE WHEN source_flag = SOURCE_FUNCTION THEN 'production'
                               WHEN source_flag = SOURCE_USER THEN 'users'
                               ELSE null END)
   AND t.first_name LIKE firstname
   AND t.last_name LIKE lastname
   AND t.employid LIKE employeeid;

The CASE statement evaluates multiple conditions to produce a single value. So, in the first usage, I check the value of status_flag, returning 'A', 'T' or null depending on what it's value is, and compare that to t.status. I do the same for the business_unit column with a second CASE statement.

Try rerunning the pod and running

 kubectl get pods --watch

to watch the status of the pod as it progresses.

In my case, I would only see the end result, 'CrashLoopBackOff,' but the docker container ran fine locally. So I watched the pods using the above command, and I saw the container briefly progress into an OOMKilled state, which meant to me that it required more memory.

It is important to be specific about what exception you're trying to catch when using a try/except block.

string = "abcd"
try:
    string_int = int(string)
    print(string_int)
except ValueError:
    # Handle the exception
    print('Please enter an integer')

Try/Excepts are powerful because if something can fail in a number of different ways, you can specify how you want the program to react in each fail case.

You should introduce a cast inside the click event handler

MouseEventArgs me = (MouseEventArgs) e;

Since Oracle 12C, you can fetch a specific number of rows with FETCH FIRST ROW ONLY. In your case this implies an ORDER BY, so the performance should be considered.

SELECT A, col_date
FROM TABLENAME t_ext
ORDER BY col_date DESC NULLS LAST
FETCH FIRST 1 ROW ONLY;

The NULLS LAST is just in case you may have null values in your field.

grep -v is your friend:

grep --help | grep invert  

-v, --invert-match select non-matching lines

Also check out the related -L (the complement of -l).

-L, --files-without-match only print FILE names containing no match

You can try SharpZipLib for that. Is is open source, platform independent pure c# code.

size_t is defined by the C standard to be the unsigned integer return type of the sizeof operator (C99 6.3.5.4.4), and the argument of malloc and friends (C99 7.20.3.3 etc). The actual range is set such that the maximum (SIZE_MAX) is at least 65535 (C99 7.18.3.2).

However, this doesn't let us determine sizeof(size_t). The implementation is free to use any representation it likes for size_t - so there is no upper bound on size - and the implementation is also free to define a byte as 16-bits, in which case size_t can be equivalent to unsigned char.

Putting that aside, however, in general you'll have 32-bit size_t on 32-bit programs, and 64-bit on 64-bit programs, regardless of the data model. Generally the data model only affects static data; for example, in GCC:

`-mcmodel=small'
     Generate code for the small code model: the program and its
     symbols must be linked in the lower 2 GB of the address space.
     Pointers are 64 bits.  Programs can be statically or dynamically
     linked.  This is the default code model.

`-mcmodel=kernel'
     Generate code for the kernel code model.  The kernel runs in the
     negative 2 GB of the address space.  This model has to be used for
     Linux kernel code.

`-mcmodel=medium'
     Generate code for the medium model: The program is linked in the
     lower 2 GB of the address space but symbols can be located
     anywhere in the address space.  Programs can be statically or
     dynamically linked, but building of shared libraries are not
     supported with the medium model.

`-mcmodel=large'
     Generate code for the large model: This model makes no assumptions
     about addresses and sizes of sections.

You'll note that pointers are 64-bit in all cases; and there's little point to having 64-bit pointers but not 64-bit sizes, after all.

Warning: this answer covers only ReactRouter versions before 1.0

I will update this answer with 1.0.0-rc1 use cases after!

You can do this without mixins too.

let Authentication = React.createClass({
  contextTypes: {
    router: React.PropTypes.func
  },
  handleClick(e) {
    e.preventDefault();
    this.context.router.transitionTo('/');
  },
  render(){
    return (<div onClick={this.handleClick}>Click me!</div>);
  }
});

The gotcha with contexts is that it is not accessible unless you define the contextTypes on the class.

As for what is context, it is an object, like props, that are passed down from parent to child, but it is passed down implicitly, without having to redeclare props each time. See https://www.tildedave.com/2014/11/15/introduction-to-contexts-in-react-js.html

Therefore, I would like to separate the string by the furthest delimiter.

I know this is an old question, but this is a simple requirement for which SUBSTR and INSTR would suffice. REGEXP are still slower and CPU intensive operations than the old subtsr and instr functions.

SQL> WITH DATA AS
  2    ( SELECT 'F/P/O' str FROM dual
  3    )
  4  SELECT SUBSTR(str, 1, Instr(str, '/', -1, 1) -1) part1,
  5         SUBSTR(str, Instr(str, '/', -1, 1) +1) part2
  6  FROM DATA
  7  /

PART1 PART2
----- -----
F/P   O

As you said you want the furthest delimiter, it would mean the first delimiter from the reverse.

You approach was fine, but you were missing the start_position in INSTR. If the start_position is negative, the INSTR function counts back start_position number of characters from the end of string and then searches towards the beginning of string.

I believe this should also do the job too:

background-size: contain;

It specifies that the image should be resized to fit within the element without losing it's aspect ratio.

It might a little bit tricky to change the color of font-awesome icons. The simpler method is to add your own class name inside the font-awesome defined classes like this:

.

And target your custom_defined__class_name in your CSS to change the color to whatever you like.

From C++11 onwards, all the standard containers (std::vector, std::map, etc) support move semantics, meaning that you can now pass rvalues to standard containers and avoid a copy:

// Example object class.
class object
{
private:
    int             m_val1;
    std::string     m_val2;

public:
    // Constructor for object class.
    object(int val1, std::string &&val2) :
        m_val1(val1),
        m_val2(std::move(val2))
    {

    }
};

std::vector<object> myList;

// #1 Copy into the vector.
object foo1(1, "foo");
myList.push_back(foo1);

// #2 Move into the vector (no copy).
object foo2(1024, "bar");
myList.push_back(std::move(foo2));

// #3 Move temporary into vector (no copy).
myList.push_back(object(453, "baz"));

// #4 Create instance of object directly inside the vector (no copy, no move).
myList.emplace_back(453, "qux");

Alternatively you can use various smart pointers to get mostly the same effect:

std::unique_ptr example

std::vector<std::unique_ptr<object>> myPtrList;

// #5a unique_ptr can only ever be moved.
auto pFoo = std::make_unique<object>(1, "foo");
myPtrList.push_back(std::move(pFoo));

// #5b unique_ptr can only ever be moved.
myPtrList.push_back(std::make_unique<object>(1, "foo"));

std::shared_ptr example

std::vector<std::shared_ptr<object>> objectPtrList2;

// #6 shared_ptr can be used to retain a copy of the pointer and update both the vector
// value and the local copy simultaneously.
auto pFooShared = std::make_shared<object>(1, "foo");
objectPtrList2.push_back(pFooShared);
// Pointer to object stored in the vector, but pFooShared is still valid.

If it's not a big/long array just mirror it:

for( int i = 0; i < arr.length/2; ++i ) 
{ 
  temp = arr[i]; 
  arr[i] = arr[arr.length - i - 1]; 
  arr[arr.length - i - 1] = temp; 
}

This will work:

ALTER TABLE [dbo].[company] DROP CONSTRAINT [Company_CountryID_FK]

Hope this Helps:

public String getSystemTimeInBelowFormat() {
    String timestamp = new SimpleDateFormat("yyyy-mm-dd 'T' HH:MM:SS.mmm-HH:SS").format(new Date());
    return timestamp;
}

this maybe help someone else, in my case the problem with the missing favicon.

use position:fixed instead of position:absolute

The first one is relative to your screen window. (not affected by scrolling)

The second one is relative to the page. (affected by scrolling)

Note : IE6 doesn't support position:fixed.

Something I recently discovered for styling Radio Buttons AND Checkboxes. Before, I had to use jQuery and other things. But this is stupidly simple.

input[type=radio] {
    padding-left:5px;
    padding-right:5px;
    border-radius:15px;

    -webkit-appearance:button;

    border: double 2px #00F;

    background-color:#0b0095;
    color:#FFF;
    white-space: nowrap;
    overflow:hidden;

    width:15px;
    height:15px;
}

input[type=radio]:checked {
    background-color:#000;
    border-left-color:#06F;
    border-right-color:#06F;
}

input[type=radio]:hover {
    box-shadow:0px 0px 10px #1300ff;
}

You can do the same for a checkbox, obviously change the input[type=radio] to input[type=checkbox] and change border-radius:15px; to border-radius:4px;.

Hope this is somewhat useful to you.

you have to add the property Tables to the DataGridView Data Source

 dataGridView1.DataSource = table.Tables[0];

['class' => 'yii\db\Connection',
    'dsn' => 'mysql:host=localhost:3306;dbname=testdb',
    'username' => 'user',
    'password' => 'password',
    'charset' => 'utf8',]

It's simple: Just provide the port number along with the host name and set default sock path to your mysql.sock file path in php.ini which the server is running on.

erickson's answer worked perfectly:

Here's the working code.

CodeSource src = MyClass.class.getProtectionDomain().getCodeSource();
List<String> list = new ArrayList<String>();

if( src != null ) {
    URL jar = src.getLocation();
    ZipInputStream zip = new ZipInputStream( jar.openStream());
    ZipEntry ze = null;

    while( ( ze = zip.getNextEntry() ) != null ) {
        String entryName = ze.getName();
        if( entryName.startsWith("images") &&  entryName.endsWith(".png") ) {
            list.add( entryName  );
        }
    }

 }
 webimages = list.toArray( new String[ list.size() ] );

And I have just modify my load method from this:

File[] webimages = ... 
BufferedImage image = ImageIO.read(this.getClass().getResource(webimages[nextIndex].getName() ));

To this:

String  [] webimages = ...

BufferedImage image = ImageIO.read(this.getClass().getResource(webimages[nextIndex]));

multipart/form-data encoded requests are indeed not by default supported by the Servlet API prior to version 3.0. The Servlet API parses the parameters by default using application/x-www-form-urlencoded encoding. When using a different encoding, the request.getParameter() calls will all return null. When you're already on Servlet 3.0 (Glassfish 3, Tomcat 7, etc), then you can use HttpServletRequest#getParts() instead. Also see this blog for extended examples.

Prior to Servlet 3.0, a de facto standard to parse multipart/form-data requests would be using Apache Commons FileUpload. Just carefully read its User Guide and Frequently Asked Questions sections to learn how to use it. I've posted an answer with a code example before here (it also contains an example targeting Servlet 3.0).

Extending Petrucio's answer with Regex.Escape on the search string, and escaping matched group as suggested in Steve B's answer (and some minor changes to my taste):

public static class StringExtensions
{
    public static string ReplaceIgnoreCase(this string str, string from, string to)
    {
        return Regex.Replace(str, Regex.Escape(from), to.Replace("$", "$$"), RegexOptions.IgnoreCase);
    }
}

Which will produce the following expected results:

Console.WriteLine("(heLLo) wOrld".ReplaceIgnoreCase("(hello) world", "Hi $1 Universe")); // Hi $1 Universe
Console.WriteLine("heLLo wOrld".ReplaceIgnoreCase("(hello) world", "Hi $1 Universe"));   // heLLo wOrld

However without performing the escapes you would get the following, which is not an expected behaviour from a String.Replace that is just case-insensitive:

Console.WriteLine("(heLLo) wOrld".ReplaceIgnoreCase_NoEscaping("(hello) world", "Hi $1 Universe")); // (heLLo) wOrld
Console.WriteLine("heLLo wOrld".ReplaceIgnoreCase_NoEscaping("(hello) world", "Hi $1 Universe"));   // Hi heLLo Universe

it worked for me

$(document).scroll(function() {
    var y = $(document).scrollTop(), //get page y value 
        header = $("#myarea"); // your div id
    if(y >= 400)  {
        header.css({position: "fixed", "top" : "0", "left" : "0"});
    } else {
        header.css("position", "static");
    }
});

I just update the pod file 'pod update' and it start to work for me normally.

will the height attribute stretch the image beyond its native resolution? If I have a image with a height of say 420 pixels, I can't get css to stretch the image beyond the native resolution to fill the height of the viewport.

I am getting pretty close results with:

 .rightdiv img {
        max-width: 25vw;
        min-height: 100vh;
    }

the 100vh is getting pretty close, with just a few pixels left over at the bottom for some reason.

Have you tried..

curl_setopt($process, CURLOPT_SSL_VERIFYPEER, false);

If you are consuming a trusted source you can skip the verify.

Try this jQuery which works in IE9, FF, Chrome and provides a countdown to users:

$("#comments").bind("keyup keydown", function() {
    var max = 500;
    var value = $(this).val();
    var left = max - value.length;
    if(left < 0) {
        $(this).val( value.slice(0, left) );
        left = 0;
    }
    $("#charcount").text(left);
}); 

<textarea id="comments" onkeyup="ismaxlength(this,500)"></textarea>
<span class="max-char-limit"><span id="charcount">500</span> characters left</span>

// Captura datos usando metodo GET en la url colocar index.html?hola=chao
const $_GET = {};
const args = location.search.substr(1).split(/&/);
for (let i=0; i<args.length; ++i) {
    const tmp = args[i].split(/=/);
    if (tmp[0] != "") {
        $_GET[decodeURIComponent(tmp[0])] = decodeURIComponent(tmp.slice(1).join("").replace("+", " "));
        console.log(`>>${$_GET['hola']}`);
    }//::END if
}//::END for

I am late here, but this might help someone looking for the answer. Typically servletRequest.getRemoteAddr() works.

In many cases your application users might be accessing your web server via a proxy server or maybe your application is behind a load balancer.

So you should access the X-Forwarded-For http header in such a case to get the user's IP address.

e.g. String ipAddress = request.getHeader("X-FORWARDED-FOR");

Hope this helps.

This code segment for your Model

function getCount($tblName){
    $query = $this->db->get($tblName);
    $rowCount = $query->num_rows();
    return $rowCount;       
}

This is for controlr

  public function index() {
    $data['employeeCount']= $this->CMS_model->getCount("employee");
    $this->load->view("hrdept/main",$data);
}

This is for view

<div class="count">
  <?php echo $employeeCount; ?>                                                                                            
 </div>

This code is used in my project and is working properly.

There are plenty of templating systems that offer more compact syntax for your views. Smarty is venerable and popular. This article lists 10 others.

Pointers are not always the same size on the same architecture.

You can read more on the concept of "near", "far" and "huge" pointers, just as an example of a case where pointer sizes differ...

http://en.wikipedia.org/wiki/Intel_Memory_Model#Pointer_sizes

1) Why does the x-axis (frequency) end at 500? How do I know that there aren't more frequencies or are they just ignored?

It ends at 500Hz because that is the Nyquist frequency of the signal when sampled at 1000Hz. Look at this line in the Mathworks example:

f = Fs/2*linspace(0,1,NFFT/2+1);

The frequency axis of the second plot goes from 0 to Fs/2, or half the sampling frequency. The Nyquist frequency is always half the sampling frequency, because above that, aliasing occurs:

The signal would "fold" back on itself, and appear to be some frequency at or below 500Hz.

2) How do I know the frequencies are between 0 and 500? Shouldn't the FFT tell me, in which limits the frequencies are?

Due to "folding" described above (the Nyquist frequency is also commonly known as the "folding frequency"), it is physically impossible for frequencies above 500Hz to appear in the FFT; higher frequencies will "fold" back and appear as lower frequencies.

Does the FFT only return the amplitude value without the frequency?

Yes, the MATLAB FFT function only returns one vector of amplitudes. However, they map to the frequency points you pass to it.

Let me know what needs clarification so I can help you further.

Simply use fs module and something like this:

fs.appendFile('server.log', 'string to append', function (err) {
   if (err) return console.log(err);
   console.log('Appended!');
});

  <?php 
 $target_dir = "images/";
    echo $target_file = $target_dir . basename($_FILES["image"]["name"]);
    $post_tmp_img = $_FILES["image"]["tmp_name"];
    $imageFileType = strtolower(pathinfo($target_file, PATHINFO_EXTENSION));
    $post_imag = $_FILES["image"]["name"];
        move_uploaded_file($post_tmp_img,"../images/$post_imag");
 ?>

Try the WSDL To Proxy class tool shipped with the .NET Framework SDK. I've never used it before, but it certainly looks like what you need.

There's a clone snippet here, which you can add to your model which does this:

def clone(self):
  new_kwargs = dict([(fld.name, getattr(old, fld.name)) for fld in old._meta.fields if fld.name != old._meta.pk]);
  return self.__class__.objects.create(**new_kwargs)

If you're after serialization, but won't need the data in other programs, I strongly recommend the shelve module. Think of it as a persistent dictionary.

myData = shelve.open('/path/to/file')

# Check for values.
keyVar in myData

# Set values
myData[anotherKey] = someValue

# Save the data for future use.
myData.close()

UPDATE 2018-10-21:

As of this week, getRootDir() was deprecated. Please use getProjectDir() instead, as suggested in the comment section by Muzaraf Ali.

—-

Use this:

$this->get('kernel')->getRootDir();

And if you want the web root:

$this->get('kernel')->getRootDir() . '/../web' . $this->getRequest()->getBasePath();

this will work from controller action method...

EDIT: As for the services, I think the way you did it is as clean as possible, although I would pass complete kernel service as an argument... but this will also do the trick...

you can loop through all attributes like you do with nodes

foreach (XmlNode item in node.ChildNodes)
{ 
    // node stuff...

    foreach (XmlAttribute att in item.Attributes)
    {
        // attribute stuff
    }
}

The best way is not to write your own funcion.

Let me explain the motivaion - please lookup the official Android source code.

In TypedValue.java we have:

    public static int complexToDimensionPixelSize(int data,
            DisplayMetrics metrics)
    {
        final float value = complexToFloat(data);
        final float f = applyDimension(
                (data>>COMPLEX_UNIT_SHIFT)&COMPLEX_UNIT_MASK,
                value,
                metrics);
        final int res = (int) ((f >= 0) ? (f + 0.5f) : (f - 0.5f));
        if (res != 0) return res;
        if (value == 0) return 0;
        if (value > 0) return 1;
        return -1;
    }

and:

    public static float applyDimension(int unit, float value,
                                       DisplayMetrics metrics)
    {
        switch (unit) {
        case COMPLEX_UNIT_PX:
            return value;
        case COMPLEX_UNIT_DIP:
            return value * metrics.density;
        case COMPLEX_UNIT_SP:
            return value * metrics.scaledDensity;
        case COMPLEX_UNIT_PT:
            return value * metrics.xdpi * (1.0f/72);
        case COMPLEX_UNIT_IN:
            return value * metrics.xdpi;
        case COMPLEX_UNIT_MM:
            return value * metrics.xdpi * (1.0f/25.4f);
        }
        return 0;
    }

As you can see, DisplayMetrics metrics can differ, which means it would yield different values across Android-OS powered devices.

I strongly recommend putting your dp padding in dimen xml file and use the official Android conversions to have consistent behaviour with regard to how Android framework works.

The same, Server.UrlEncode() calls HttpUtility.UrlEncode()

This article MEM10-C. Define and use a pointer validation function says it is possible to do a check to some degree, especially under Linux OS.

setAutoSize method must come before setWidth:

$objPHPExcel->getActiveSheet()->getColumnDimensionByColumn('C')->setAutoSize(false);
$objPHPExcel->getActiveSheet()->getColumnDimensionByColumn('C')->setWidth('10');

Consider an example dataframe

df =     
index    column1
0           00
1           10
2           20
3           30

we want to drop 2nd and 3rd index rows.

Approach 1:

df = df.drop(df.index[2,3])
 or 
df.drop(df.index[2,3],inplace=True)
print(df)

df =     
index    column1
0           00
3           30

 #This approach removes the rows as we wanted but the index remains unordered

Approach 2

df.drop(df.index[2,3],inplace=True,ignore_index=True)
print(df)
df =     
index    column1
0           00
1           30
#This approach removes the rows as we wanted and resets the index. 

You can use percentage for (JUST) windows dialog width.

Look into this example from Holo Theme:

<style name="Theme.Holo.Dialog.NoActionBar.MinWidth">
    <item name="android:windowMinWidthMajor">@android:dimen/dialog_min_width_major</item>
    <item name="android:windowMinWidthMinor">@android:dimen/dialog_min_width_minor</item>
</style>

 <!-- The platform's desired minimum size for a dialog's width when it
     is along the major axis (that is the screen is landscape).  This may
     be either a fraction or a dimension. -->
<item type="dimen" name="dialog_min_width_major">65%</item>

All you need to do is extend this theme and change the values for "Major" and "Minor" to 90% instead 65%.

Regards.

You can get the type of "T" from any collection type that implements IEnumerable<T> with the following:

public static Type GetCollectionItemType(Type collectionType)
{
    var types = collectionType.GetInterfaces()
        .Where(x => x.IsGenericType 
            && x.GetGenericTypeDefinition() == typeof(IEnumerable<>))
        .ToArray();
    // Only support collections that implement IEnumerable<T> once.
    return types.Length == 1 ? types[0].GetGenericArguments()[0] : null;
}

Note that it doesn't support collection types that implement IEnumerable<T> twice, e.g.

public class WierdCustomType : IEnumerable<int>, IEnumerable<string> { ... }

I suppose you could return an array of types if you needed to support this...

Also, you might also want to cache the result per collection type if you're doing this a lot (e.g. in a loop).

You need to include the path of the libraries inside /etc/ld.so.conf, and rerun ldconfig to upate the list

Other possibility is to include in the env variable LD_LIBRARY_PATH the path to your library, and rerun the executable.

check the symbolic links if they point to a valid library ...

You can add the path directly in /etc/ld.so.conf, without include...

run ldconfig -p to see whether your library is well included in the cache.

Yes you can. Example :

DELETE TableA 
FROM TableA AS a
INNER JOIN TableB AS b
ON a.BId = b.BId
WHERE [filter condition]

Search with a regular expression:

^.*(help).*$

Use jps to list running java processes. The command returns the process id along with the main class. You can use kill command to kill the process with the returned id or use following one liner script.

kill $(jps | grep <MainClass> | awk '{print $1}')

MainClass is a class in your running java program which contains the main method.

Yes: you can hide the built-in browser UI (by removing the controls attribute from audio) and instead build your own interface and control the playback using Javascript (source):

<audio id="player" src="vincent.mp3"></audio>
<div> 
  <button onclick="document.getElementById('player').play()">Play</button> 
  <button onclick="document.getElementById('player').pause()">Pause</button> 
  <button onclick="document.getElementById('player').volume += 0.1">Vol +</button> 
  <button onclick="document.getElementById('player').volume -= 0.1">Vol -</button> 
</div>

You can then style the elements however you wish using CSS.

MDN HTMLAudioElement API reference

Anaconda is a very large installation ~ 2 GB and is most useful for those users who are not familiar with installing modules or packages with other package managers.

Anaconda seems to be promoting itself as the official package manager of Jupyter. It's not. Anaconda bundles Jupyter, R, python, and many packages with its installation.

Anaconda is not necessary for installing Jupyter Lab or the R kernel. There is plenty of information available elsewhere for installing Jupyter Lab or Notebooks. There is also plenty of information elsewhere for installing R studio. The following shows how to install the R kernel directly from R Studio:

To install the R kernel, without Anaconda, start R Studio. In the R terminal window enter these three commands:

install.packages("devtools")
devtools::install_github("IRkernel/IRkernel")
IRkernel::installspec()

Done. Next time Jupyter is opened, the R kernel will be available.

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

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

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

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

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

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

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

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

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

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

res="\t\tx"
echo -e "[${res}]"

Try these to clarify the issue of right alignment in float point printing

printf(" 4|%4.1lf\n", 8.9);
printf("04|%04.1lf\n", 8.9);

the output is

 4| 8.9
04|08.9

# Hide grid lines
ax.grid(False)

# Hide axes ticks
ax.set_xticks([])
ax.set_yticks([])
ax.set_zticks([])

Note, you need matplotlib>=1.2 for set_zticks() to work.

My answer is similar to this one on ServerFault.com.

To Be Conservative

If you want to be more conservative than granting "all privileges", you might want to try something more like these.

GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO some_user_;
GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA public TO some_user_;

The use of public there refers to the name of the default schema created for every new database/catalog. Replace with your own name if you created a schema.

Access to the Schema

To access a schema at all, for any action, the user must be granted "usage" rights. Before a user can select, insert, update, or delete, a user must first be granted "usage" to a schema.

You will not notice this requirement when first using Postgres. By default every database has a first schema named public. And every user by default has been automatically been granted "usage" rights to that particular schema. When adding additional schema, then you must explicitly grant usage rights.

GRANT USAGE ON SCHEMA some_schema_ TO some_user_ ;

Excerpt from the Postgres doc:

For schemas, allows access to objects contained in the specified schema (assuming that the objects' own privilege requirements are also met). Essentially this allows the grantee to "look up" objects within the schema. Without this permission, it is still possible to see the object names, e.g. by querying the system tables. Also, after revoking this permission, existing backends might have statements that have previously performed this lookup, so this is not a completely secure way to prevent object access.

For more discussion see the Question, What GRANT USAGE ON SCHEMA exactly do?. Pay special attention to the Answer by Postgres expert Craig Ringer.

Existing Objects Versus Future

These commands only affect existing objects. Tables and such you create in the future get default privileges until you re-execute those lines above. See the other answer by Erwin Brandstetter to change the defaults thereby affecting future objects.

On Servlet 3.0 or newer you could just specify

<web-app ...>
    <error-page>
        <location>/general-error.html</location>
    </error-page>
</web-app>

But as you're still on Servlet 2.5, there's no other way than specifying every common HTTP error individually. You need to figure which HTTP errors the enduser could possibly face. On a barebones webapp with for example the usage of HTTP authentication, having a disabled directory listing, using custom servlets and code which can possibly throw unhandled exceptions or does not have all methods implemented, then you'd like to set it for HTTP errors 401, 403, 500 and 503 respectively.

<error-page>
    <!-- Missing login -->
    <error-code>401</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Forbidden directory listing -->
    <error-code>403</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Missing resource -->
    <error-code>404</error-code>
    <location>/Error404.html</location>
</error-page>
<error-page>
    <!-- Uncaught exception -->
    <error-code>500</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Unsupported servlet method -->
    <error-code>503</error-code>
    <location>/general-error.html</location>
</error-page>

That should cover the most common ones.

There are really nice answers for this particular question, so there is no point to write my own explanation. So I will try to contribute with an excellent resource about different classes of computational complexity.

For someone who thinks that computational complexity is only about P and NP, here is the most exhaustive resource about different computational complexity problems. Apart from problems asked by OP, it listed approximately 500 different classes of computational problems with nice descriptions and also the list of fundamental research papers which describe the class.

I know this is an old question, but this will do the job.

SELECT colname, typename, length, scale, default, nulls
  FROM syscat.columns
 WHERE tabname = '<table name>'
   AND tabschema = '<schema name>'

((TextView) findViewById(R.id.tv_cgu)).setText(Html.fromHtml(getString(R.string.upload_poi_CGU)));

<string name="upload_poi_CGU"><![CDATA[ J\'accepte les <a href="">conditions générales</a>]]></string>

In your project root folder open .git/config. This file has details about remote url and your credentials type.

Your current remote url in this file might be storing credentials. Copy remote url from github and update the url in this config file.

Like below:

[remote "origin"]
    url = [update it]
    fetch = +refs/heads/*:refs/remotes/origin/*
[credential]
    helper = manager

Now when you try to push your code it will ask for credentials. Thanks

As mentioned by another poster, Visual Studio generates this as a part of its .gitignore (at least for MVC 4):

# SQL Server files
App_Data/*.mdf
App_Data/*.ldf

Since your project may be a subfolder of your solution, and the .gitignore file is stored in the solution root, this actually won't touch the local database files (Git sees them at projectfolder/App_Data/*.mdf). To account for this, I changed those lines like so:

# SQL Server files
*App_Data/*.mdf
*App_Data/*.ldf

For checking type conversions in version 3, you can go to their github and check into the different liquibase types and check the method toDatabaseDataType. For example, for Boolean, you can check here:

https://github.com/liquibase/liquibase/blob/master/liquibase-core/src/main/java/liquibase/datatype/core/BooleanType.java

For version 2.0.x, the conversion seems to be into database specific classes. For example, for Mysql:

https://github.com/liquibase/liquibase/blob/2_0_x/liquibase-core/src/main/java/liquibase/database/typeconversion/core/MySQLTypeConverter.java

Micah's solution below worked for me as the site I had to customise was not in UTF-8, so I could not use json; I'd vote it up but my rep isn't high enough.

function escapeJavaScriptText($string) 
{ 
    return str_replace("\n", '\n', str_replace('"', '\"', addcslashes(str_replace("\r", '', (string)$string), "\0..\37'\\"))); 
} 

! is a logical NOT operator, it's a boolean operator that will invert something to its opposite.

Although you can bypass the parentheses of the invoked function by using the BANG (!) before the function, it will still invert the return, which might not be what you wanted. As in the case of an IEFE, it would return undefined, which when inverted becomes the boolean true.

Instead, use the closing parenthesis and the BANG (!) if needed.

// I'm going to leave the closing () in all examples as invoking the function with just ! and () takes away from what's happening.

(function(){ return false; }());
=> false

!(function(){ return false; }());
=> true

!!(function(){ return false; }());
=> false

!!!(function(){ return false; }());
=> true

Other Operators that work...

+(function(){ return false; }());
=> 0

-(function(){ return false; }());
=> -0

~(function(){ return false; }());
=> -1

Combined Operators...

+!(function(){ return false; }());
=> 1

-!(function(){ return false; }());
=> -1

!+(function(){ return false; }());
=> true

!-(function(){ return false; }());
=> true

~!(function(){ return false; }());
=> -2

~!!(function(){ return false; }());
=> -1

+~(function(){ return false; }());
+> -1

Whether you're using Team System Test or NUnit, the best practice is to create a separate Class Library for your tests. Simply adding an App.config to your Test project will automatically get copied to your bin folder when you compile.

If your code is reliant on specific configuration tests, the very first test I would write validates that the configuration file is available (so that I know I'm not insane) :

<configuration>
   <appSettings>
       <add key="TestValue" value="true" />
   </appSettings>
</configuration>

And the test:

[TestFixture]
public class GeneralFixture
{
     [Test]
     public void VerifyAppDomainHasConfigurationSettings()
     {
          string value = ConfigurationManager.AppSettings["TestValue"];
          Assert.IsFalse(String.IsNullOrEmpty(value), "No App.Config found.");
     }
}

Ideally, you should be writing code such that your configuration objects are passed into your classes. This not only separates you from the configuration file issue, but it also allows you to write tests for different configuration scenarios.

public class MyObject
{
     public void Configure(MyConfigurationObject config)
     {
          _enabled = config.Enabled;
     }

     public string Foo()
     {
         if (_enabled)
         {
             return "foo!";
         }
         return String.Empty;
     }

     private bool _enabled;
}

[TestFixture]
public class MyObjectTestFixture
{
     [Test]
     public void CanInitializeWithProperConfig()
     {
         MyConfigurationObject config = new MyConfigurationObject();
         config.Enabled = true;

         MyObject myObj = new MyObject();
         myObj.Configure(config);

         Assert.AreEqual("foo!", myObj.Foo());
     }
}

EDMX model won't work with EF7 but I've found a Community/Professional product which seems to be very powerfull : http://www.devart.com/entitydeveloper/editions.html

None of these worked for me. I think i already had mysql somewhere on my computer so a password was set there or something. After spending hours trying every solution out there this is what worked for me:

$ brew services stop mysql
$ pkill mysqld
$ rm -rf /usr/local/var/mysql/ # NOTE: this will delete your existing database!!!
$ brew postinstall mysql
$ brew services restart mysql
$ mysql -uroot

The best answer works perfectly fine but in most cases, it is overkill and inefficient to loop through all the label elements.

Here is an efficent function to get the label that goes with the input element:

function getLabelForInput(id)
{
    var el = document.getElementById(id);
    if (!el)
        return null;
    var elPrev = el.previousElementSibling;
    var elNext = el.nextElementSibling;
    while (elPrev || elNext)
    {
        if (elPrev)
        {
            if (elPrev.htmlFor === id)
                return elPrev;
            elPrev = elPrev.previousElementSibling;
        }
        if (elNext)
        {
            if (elNext.htmlFor === id)
                return elNext;
            elNext = elNext.nextElementSibling;
        }
    }
    return null;
}

For me, this one line of code was sufficient:

el = document.getElementById(id).previousElementSibling;

In most cases, the label will be very close or next to the input, which means the loop in the above function only needs to iterate a very small number of times.

I have found when I am using a manifest that the listing of jars for the classpath need to have a space after the listing of each jar e.g. "required_lib/sun/pop3.jar required_lib/sun/smtp.jar ". Even if it is the last in the list.

In the following line.

temp.Response = db.Responses.Where(y => y.ResponseId.Equals(item.ResponseId)).First();

You are calling First but the collection returned from db.Responses.Where is empty.

You might also consider adding ".

For example for %i in (*.wav) do opusenc "%~ni.wav" "%~ni.opus" is very good idea.

You should also ensure you set a reference to WindowsBase. This is required to use the SDK as it handles System.IO.Packaging (which is used for unzipping and opening the compressed .docx/.xlsx/.pptx as an OPC document).

Use the following regular expression:

^\d{4}-\d{2}-\d{2}$

as in

if (str.matches("\\d{4}-\\d{2}-\\d{2}")) {
    ...
}

With the matches method, the anchors ^ and $ (beginning and end of string, respectively) are present implicitly.

To have the same flexibility in CONCAT_WS as in CONCAT (if you don't want the same separator between every member for instance) use the following:

SELECT CONCAT_WS("",affiliate_name,':',model,'-',ip,... etc)

To stick with the Maven terms:

• "clean" is a phase of the clean lifecycle
• "install" is a phase of the default lifecycle

Another possible solution. Count empty cells and subtract that value from the total number of cells

Sub Emptys()

Dim r As range
Dim totalCells As Integer

'My range To check'
Set r = ActiveSheet.range("A1:B5")

'Check for filled cells'
totalCells = r.Count- WorksheetFunction.CountBlank(r)


If totalCells = 0 Then
    MsgBox "Range is empty"
Else
    MsgBox "Range is not empty"
End If

End Sub

Use application/javascript as content type instead of text/javascript

text/javascript is mentioned obsolete. See reference docs.

http://www.iana.org/assignments/media-types/application

Also see this question on SO.

UPDATE:

I have tried executing the code you have given and the below didn't work.

res.setHeader('content-type', 'text/javascript');
res.send(JS_Script);

This is what worked for me.

res.setHeader('content-type', 'text/javascript');
res.end(JS_Script);

As robertklep has suggested, please refer to the node http docs, there is no response.send() there.

As the top answer here is suggesting something wrong (or at least too complicated), I feel this should be updated, although the question is quite old:

When using String resources in Android, you just have to call getString(...) from Java code or use android:text="@string/..." in your layout XML.

Even if you want to use HTML markup in your Strings, you don't have to change a lot:

The only characters that you need to escape in your String resources are:

• double quotation mark: " becomes \"
• single quotation mark: ' becomes \'
• ampersand: & becomes & or &

That means you can add your HTML markup without escaping the tags:

<string name="my_string"><b>Hello World!</b> This is an example.</string>

However, to be sure, you should only use <b>, <i> and <u> as they are listed in the documentation.

If you want to use your HTML strings from XML, just keep on using android:text="@string/...", it will work fine.

The only difference is that, if you want to use your HTML strings from Java code, you have to use getText(...) instead of getString(...) now, as the former keeps the style and the latter will just strip it off.

It's as easy as that. No CDATA, no Html.fromHtml(...).

You will only need Html.fromHtml(...) if you did encode your special characters in HTML markup. Use it with getString(...) then. This can be necessary if you want to pass the String to String.format(...).

This is all described in the docs as well.

Edit:

There is no difference between getText(...) with unescaped HTML (as I've proposed) or CDATA sections and Html.fromHtml(...).

See the following graphic for a comparison:

you are calling the context of not existing activity...so just replace your code in onClick(View v) as Intent intent=new Intent(this,Katra_home.class); startActivity(intent); it will definitely works....

Use "blur": http://docs.jquery.com/Events/blur#fn

Now you should be able to use the new proxy integration type for Lambda to automatically get the full request in standard shape, rather than configure mappings.

see: http://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-set-up-simple-proxy.html#api-gateway-set-up-lambda-proxy-integration-on-proxy-resource

Exit code 137 (128+9) indicates that your program exited due to receiving signal 9, which is SIGKILL. This also explains the killed message. The question is, why did you receive that signal?

The most likely reason is probably that your process crossed some limit in the amount of system resources that you are allowed to use. Depending on your OS and configuration, this could mean you had too many open files, used too much filesytem space or something else. The most likely is that your program was using too much memory. Rather than risking things breaking when memory allocations started failing, the system sent a kill signal to the process that was using too much memory.

As I commented earlier, one reason you might hit a memory limit after printing finished counting is that your call to counter.items() in your final loop allocates a list that contains all the keys and values from your dictionary. If your dictionary had a lot of data, this might be a very big list. A possible solution would be to use counter.iteritems() which is a generator. Rather than returning all the items in a list, it lets you iterate over them with much less memory usage.

So, I'd suggest trying this, as your final loop:

for key, value in counter.iteritems():
    writer.writerow([key, value])

Note that in Python 3, items returns a "dictionary view" object which does not have the same overhead as Python 2's version. It replaces iteritems, so if you later upgrade Python versions, you'll end up changing the loop back to the way it was.

Rather than disabling the xdebug, you can set the higher limit like

xdebug.max_nesting_level=500

I realize there are dozens of answers here. I want to share my solution, which ensures true private variables in ES6 classes and in older JS.

var MyClass = (function() {
    var $ = new WeakMap();
    function priv(self) {
       var r = $.get(self);
       if (!r) $.set(self, r={});
       return r;
    }

    return class { /* use $(this).prop inside your class */ } 
}();

Privacy is ensured by the fact that the outside world don't get access to $.

When the instance goes away, the WeakMap will release the data.

This definitely works in plain Javascript, and I believe they work in ES6 classes but I haven't tested that $ will be available inside the scope of member methods.

The Rob Evans anwser works correctly for me but when I use request.abort(), it occurs to throw a socket hang up error which stays unhandled.

I had to add an error handler for the request object :

var options = { ... }
var req = http.request(options, function(res) {
  // Usual stuff: on(data), on(end), chunks, etc...
}

req.on('socket', function (socket) {
    socket.setTimeout(myTimeout);  
    socket.on('timeout', function() {
        req.abort();
    });
}

req.on('error', function(err) {
    if (err.code === "ECONNRESET") {
        console.log("Timeout occurs");
        //specific error treatment
    }
    //other error treatment
});

req.write('something');
req.end();

Please find below code if you want user to restrict with entering 10 digit in input control

<input class="form-control  input-md text-box single-line" id="ContactNumber" max="9999999999" min="1000000000" name="ContactNumber" required="required" type="number"  value="9876658688">

Benefits -

1. It will not allow to type any alphabets in input box because type of input box is 'number'

2. it will allow max 10 digits because max property is set to maximum possible value in 10 digits

3. it will not allow user to enter anything less than 10 digits as we want to restrict user in 10 digit phone number. min property in code is having minimum possible value in 10 digits so it will tell user to enter valid 10 digit value not less than that.

The size_t type is defined as the unsigned integral type of the sizeof operator. In the real world, you will often see int defined as 32 bits (for backward compatibility) but size_t defined as 64 bits (so you can declare arrays and structures more than 4 GiB in size) on 64-bit platforms. If a long int is also 64-bits, this is called the LP64 convention; if long int is 32 bits but long long int and pointers are 64 bits, that’s LLP64. You also might get the reverse, a program that uses 64-bit instructions for speed, but 32-bit pointers to save memory. Also, int is signed and size_t is unsigned.

There were historically a number of other platforms where addresses were wider or shorter than the native size of int. In fact, in the ’70s and early ’80s, this was more common than not: all the popular 8-bit microcomputers had 8-bit registers and 16-bit addresses, and the transition between 16 and 32 bits also produced many machines that had addresses wider than their registers. I occasionally still see questions here about Borland Turbo C for MS-DOS, whose Huge memory mode had 20-bit addresses stored in 32 bits on a 16-bit CPU (but which could support the 32-bit instruction set of the 80386); the Motorola 68000 had a 16-bit ALU with 32-bit registers and addresses; there were IBM mainframes with 15-bit, 24-bit or 31-bit addresses. You also still see different ALU and address-bus sizes in embedded systems.

Any time int is smaller than size_t, and you try to store the size or offset of a very large file or object in an unsigned int, there is the possibility that it could overflow and cause a bug. With an int, there is also the possibility of getting a negative number. If an int or unsigned int is wider, the program will run correctly but waste memory.

You should generally use the correct type for the purpose if you want portability. A lot of people will recommend that you use signed math instead of unsigned (to avoid nasty, subtle bugs like 1U < -3). For that purpose, the standard library defines ptrdiff_t in <stddef.h> as the signed type of the result of subtracting a pointer from another.

That said, a workaround might be to bounds-check all addresses and offsets against INT_MAX and either 0 or INT_MIN as appropriate, and turn on the compiler warnings about comparing signed and unsigned quantities in case you miss any. You should always, always, always be checking your array accesses for overflow in C anyway.

Make use of find's options

There is actually no exec of /bin/ls needed;

Find has an option that does just that:

find . -maxdepth 2 -type d -ls

To see only the one level of subdirectories you are interested in, add -mindepth to the same level as -maxdepth:

find . -mindepth 2 -maxdepth 2 -type d -ls

Use output formatting

When the details that get shown should be different, -printf can show any detail about a file in custom format; To show the symbolic permissions and the owner name of the file, use -printf with %M and %u in the format.

I noticed later you want the full ownership information, which includes the group. Use %g in the format for the symbolic name, or %G for the group id (like also %U for numeric user id)

find . -mindepth 2 -maxdepth 2 -type d -printf '%M %u %g %p\n'

This should give you just the details you need, for just the right files.

I will give an example that shows actually different values for user and group:

$ sudo find /tmp -mindepth 2 -maxdepth 2 -type d -printf '%M %u %g %p\n'
drwx------ www-data  www-data /tmp/user/33
drwx------ octopussy root     /tmp/user/126
drwx------ root      root     /tmp/user/0
drwx------ siegel    root     /tmp/user/1000
drwxrwxrwt root      root     /tmp/systemd-[...].service-HRUQmm/tmp

Notes on performance

Although the execution time is mostly irrelevant for this kind of command, increase in performance is large enough here to make it worth pointing it out:

Not only do we save creating a new process for each name - a huge task - the information does not even need to be read, as find already knows it.

The "Getting Started" page is the introduction to the documentation. Most documentation will start off with installation instructions, just like Composer's do.

The page that contains information on the composer.json file is located here - under "Basic Usage", the second page.

I'd recommend reading over the documentation in full, so that you gain a better understanding of how to use Composer. I'd also recommend removing what you have and following the installation instructions provided in the documentation.

open C:\myfile.txt for append as #1
write #1, text1.text, text2.text
close()

This is the code I use in Visual Basic 6.0. It helps me to create a txt file on my drive, write two pieces of data into it, and then close the file... Give it a try...

I had serious issues with Timezones and such. The way Python handles all that happen to be pretty confusing (to me). Things seem to be working fine using the calendar module (see links 1, 2, 3 and 4).

>>> import datetime
>>> import calendar
>>> aprilFirst=datetime.datetime(2012, 04, 01, 0, 0)
>>> calendar.timegm(aprilFirst.timetuple())

Hi as @andrew mentioned make cellpadding = 0, you still might have some space as you are using table border=1.

In the tour guide app of Udacity's Basic ANdroid course I have used the concept of Fragments. I got stuck for a while experiencing difficulty to access some string resources described in strings, xml file. Finally got a solution.

This is the main activity class

package com.example.android.tourguidekolkata;

import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState)
{
  //lines of code
   //lines of code
    //lines of code
    YourClass adapter = new YourClass(getSupportFragmentManager(), getApplicationContext()); 
    //lines of code
    // getApplicationContext() method passses the Context of main activity to the class TourFragmentPageAdapter 
}
}

This is the non Activity class that extends FragmentPageAdapter

public class YourClass extends FragmentPagerAdapter {
private String yourStringArray[] = new String[4];
Context context;

public YourClass (FragmentManager fm, Context context)
{
    super(fm);
    this.context = context; // store the context of main activity
    // now you can use this context to access any resource 
    yourStringArray[0] = context.getResources().getString(R.string.tab1);
    yourStringArray[1] = context.getResources().getString(R.string.tab2);
    yourStringArray[2] = context.getResources().getString(R.string.tab3);
    yourStringArray[3] = context.getResources().getString(R.string.tab4);
}
@Override
public Fragment getItem(int position)
 {
 }
@Override
public int getCount() {
return 4;
}

@Override
public CharSequence getPageTitle(int position) {
// Generate title based on item position
return yourStringArras[position];
}
}

On Arch, i fix like this:

sudo ln -s /usr/lib/libncursesw.so.6 /usr/lib/libtinfo.so.6

This will stream the byte data into json.

import io

obj = json.load(io.TextIOWrapper(response))

io.TextIOWrapper is preferred to the codec's module reader. https://www.python.org/dev/peps/pep-0400/

the css solution works, however you do not really get control on the styling. In my case I wanted a bit more space after the line break. Here is a directive I created to handle this (typescript):

function preDirective(): angular.IDirective {
    return {
        restrict: 'C',
        priority: 450,
        link: (scope, el, attr, ctrl) => {
            scope.$watch(
                () => el[0].innerHTML,
                (newVal) => {
                    let lineBreakIndex = newVal.indexOf('\n');
                    if (lineBreakIndex > -1 && lineBreakIndex !== newVal.length - 1 && newVal.substr(lineBreakIndex + 1, 4) != '</p>') {
                        let newHtml = `<p>${replaceAll(el[0].innerHTML, '\n\n', '\n').split('\n').join('</p><p>')}</p>`;
                        el[0].innerHTML = newHtml;
                    }
                }
            )
        }
    };

    function replaceAll(str, find, replace) {
        return str.replace(new RegExp(escapeRegExp(find), 'g'), replace);
    }

    function escapeRegExp(str) {
        return str.replace(/([.*+?^=!:${}()|\[\]\/\\])/g, "\\$1");
    }
}

angular.module('app').directive('pre', preDirective);

Use:

<div class="pre">{{item.description}}</div>

All it does is wraps each part of the text in to a <p> tag. After that you can style it however you want.

To hide the prompt set xls.DisplayAlerts = False

ConflictResolution is not a true or false property, it should be xlLocalSessionChanges

Note that this has nothing to do with displaying the Overwrite prompt though!

Set xls = CreateObject("Excel.Application")    
xls.DisplayAlerts = False
Set wb = xls.Workbooks.Add
fullFilePath = importFolderPath & "\" & "A.xlsx"

wb.SaveAs fullFilePath, AccessMode:=xlExclusive,ConflictResolution:=Excel.XlSaveConflictResolution.xlLocalSessionChanges    
wb.Close (True)

In my maven project this error occurs, after i closed my projects and reopens them. The dependencys wasn´t build correctly at that time. So for me the solution was just to update the Maven Dependencies of the projects!

To add all file at a time, use git add -A

To check git whole status, use git log

you must change php_admin_value max_execution_time in your Alias config (\XAMPP\alias\phpmyadmin.conf)

answer is here: WAMPServer phpMyadmin Maximum execution time of 360 seconds exceeded

You should be using posts with proper expires and caching headers.

plugin ConverToUTF8 also has the functionality.

In my case I got rid of the exception by replacing SetDataAndType with just SetData.

You can also use chr(176) to print the degree sign. Here is an example using python 3.6.5 interactive shell:

Apart from what Andy mentioned, there is another difference which could be important - write-host directly writes to the host and return nothing, meaning that you can't redirect the output, e.g., to a file.

---- script a.ps1 ----
write-host "hello"

Now run in PowerShell:

PS> .\a.ps1 > someFile.txt
hello
PS> type someFile.txt
PS>

As seen, you can't redirect them into a file. This maybe surprising for someone who are not careful.

But if switched to use write-output instead, you'll get redirection working as expected.

Although I'm not sure why you want to create CSS classes with JavaScript, here is an option:

var style = document.createElement('style');
style.type = 'text/css';
style.innerHTML = '.cssClass { color: #F00; }';
document.getElementsByTagName('head')[0].appendChild(style);

document.getElementById('someElementId').className = 'cssClass';

The reason I was looking for such a solution is simply to add spaces between multiple DFs which have been joined column-wise using the pd.concat function and then written to excel using xlsxwriter.

df[' ']=df.apply(lambda _: '', axis=1)
df_2 = pd.concat([df,df1],axis=1)                #worked but only once. 
# Note: df & df1 have the same rows which is my index. 
#
df_2[' ']=df_2.apply(lambda _: '', axis=1)       #didn't work this time !!?     
df_4 = pd.concat([df_2,df_3],axis=1)

I then replaced the second lambda call with

df_2['']=''                                 #which appears to add a blank column
df_4 = pd.concat([df_2,df_3],axis=1)

The output I tested it on was using xlsxwriter to excel. Jupyter blank columns look the same as in excel although doesnt have xlsx formatting. Not sure why the second Lambda call didnt work.

Do it this way (make necessary changes in code)..

            con.Open();
            SqlCommand cmd = new SqlCommand("CheckUser", con);
            cmd.CommandType = CommandType.StoredProcedure;
            SqlParameter p1 = new SqlParameter("username", username.Text);
            SqlParameter p2 = new SqlParameter("password", password.Text);
            cmd.Parameters.Add(p1);
            cmd.Parameters.Add(p2);
            SqlDataReader rd = cmd.ExecuteReader();
            if(rd.HasRows)
            {
                //do the things
            }
            else
            {
                lblinfo.Text = "abc";
            }

You can just initialize via a constructor:

struct address {
  address() : city("Hamilton"), prov("Ontario") {}
  int street_no;
  char *street_name;
  char *city;
  char *prov;
  char *postal_code;
};

There are all sorts of things which can do this. One possiblity is "Traffic Shaping". This is commonly done in office environments to reserve bandwidth for business critical activities. It may also be done by the web hosting company, or by your ISP, for very similar reasons.

You can also set it up at home very simply.

For example there may be a rule reserving minimum bandwidth for FTP, while SFTP might be falling under an "everything else" rule. Or there might be a rule capping bandwidth for SFTP, but someone else is also using SFTP at the same time as you.

So: Where are you tranferring the file from and to?

To sort by MULTIPLE COLUMN (Sort by column_1, and then sort by column_2)

with open('unsorted.csv',newline='') as csvfile:
    spamreader = csv.DictReader(csvfile, delimiter=";")
    sortedlist = sorted(spamreader, key=lambda row:(row['column_1'],row['column_2']), reverse=False)


with open('sorted.csv', 'w') as f:
    fieldnames = ['column_1', 'column_2', column_3]
    writer = csv.DictWriter(f, fieldnames=fieldnames)
    writer.writeheader()
    for row in sortedlist:
        writer.writerow(row)

You can't set the input value in most browsers, but what you can do is create a new element, copy the attributes from the old element, and swap the two.

Given a form like:

<form> 
    <input id="fileInput" name="fileInput" type="file" /> 
</form>

The straight DOM way:

function clearFileInput(id) 
{ 
    var oldInput = document.getElementById(id); 

    var newInput = document.createElement("input"); 

    newInput.type = "file"; 
    newInput.id = oldInput.id; 
    newInput.name = oldInput.name; 
    newInput.className = oldInput.className; 
    newInput.style.cssText = oldInput.style.cssText; 
    // TODO: copy any other relevant attributes 

    oldInput.parentNode.replaceChild(newInput, oldInput); 
}

clearFileInput("fileInput");

Simple DOM way. This may not work in older browsers that don't like file inputs:

oldInput.parentNode.replaceChild(oldInput.cloneNode(), oldInput);

The jQuery way:

$("#fileInput").replaceWith($("#fileInput").val('').clone(true));

// .val('') required for FF compatibility as per @nmit026

In addition to the suggested,

String Text = mySpinner.getSelectedItem().toString();

You can do,

String Text = String.valueOf(mySpinner.getSelectedItem());

First, a definition, since it's pretty important: A stable sort is one that's guaranteed not to reorder elements with identical keys.

Recommendations:

Quick sort: When you don't need a stable sort and average case performance matters more than worst case performance. A quick sort is O(N log N) on average, O(N^2) in the worst case. A good implementation uses O(log N) auxiliary storage in the form of stack space for recursion.

Merge sort: When you need a stable, O(N log N) sort, this is about your only option. The only downsides to it are that it uses O(N) auxiliary space and has a slightly larger constant than a quick sort. There are some in-place merge sorts, but AFAIK they are all either not stable or worse than O(N log N). Even the O(N log N) in place sorts have so much larger a constant than the plain old merge sort that they're more theoretical curiosities than useful algorithms.

Heap sort: When you don't need a stable sort and you care more about worst case performance than average case performance. It's guaranteed to be O(N log N), and uses O(1) auxiliary space, meaning that you won't unexpectedly run out of heap or stack space on very large inputs.

Introsort: This is a quick sort that switches to a heap sort after a certain recursion depth to get around quick sort's O(N^2) worst case. It's almost always better than a plain old quick sort, since you get the average case of a quick sort, with guaranteed O(N log N) performance. Probably the only reason to use a heap sort instead of this is in severely memory constrained systems where O(log N) stack space is practically significant.

Insertion sort: When N is guaranteed to be small, including as the base case of a quick sort or merge sort. While this is O(N^2), it has a very small constant and is a stable sort.

Bubble sort, selection sort: When you're doing something quick and dirty and for some reason you can't just use the standard library's sorting algorithm. The only advantage these have over insertion sort is being slightly easier to implement.

Non-comparison sorts: Under some fairly limited conditions it's possible to break the O(N log N) barrier and sort in O(N). Here are some cases where that's worth a try:

Counting sort: When you are sorting integers with a limited range.

Radix sort: When log(N) is significantly larger than K, where K is the number of radix digits.

Bucket sort: When you can guarantee that your input is approximately uniformly distributed.

Try:

chmod -R ug+rwx <dir>

where <dir> is the directory on which you want to change permissions.

if you have many networks attached to you OS, yo must especify one of this network in the bind-addres from my.conf file. an example:

[mysqld]
bind-address = 127.100.10.234

this ip is from a ethX configuration.

I built upon @Chema solution and added resetting pointer-events and user-select. If they are set to none for an image, right-clicking it does not invoke the context menu for the image with options to view or save it.

javascript:function enableContextMenu(aggressive = true) { void(document.ondragstart=null); void(document.onselectstart=null); void(document.onclick=null); void(document.onmousedown=null); void(document.onmouseup=null); void(document.body.oncontextmenu=null); enableRightClickLight(document); if (aggressive) { enableRightClick(document); removeContextMenuOnAll('body'); removeContextMenuOnAll('img'); removeContextMenuOnAll('td'); } } function removeContextMenuOnAll(tagName) { var elements = document.getElementsByTagName(tagName); for (var i = 0; i < elements.length; i++) { enableRightClick(elements[i]); enablePointerEvents(elements[i]); } } function enableRightClickLight(el) { el || (el = document); el.addEventListener('contextmenu', bringBackDefault, true); } function enableRightClick(el) { el || (el = document); el.addEventListener('contextmenu', bringBackDefault, true); el.addEventListener('dragstart', bringBackDefault, true); el.addEventListener('selectstart', bringBackDefault, true); el.addEventListener('click', bringBackDefault, true); el.addEventListener('mousedown', bringBackDefault, true); el.addEventListener('mouseup', bringBackDefault, true); } function restoreRightClick(el) { el || (el = document); el.removeEventListener('contextmenu', bringBackDefault, true); el.removeEventListener('dragstart', bringBackDefault, true); el.removeEventListener('selectstart', bringBackDefault, true); el.removeEventListener('click', bringBackDefault, true); el.removeEventListener('mousedown', bringBackDefault, true); el.removeEventListener('mouseup', bringBackDefault, true); } function bringBackDefault(event) { event.returnValue = true; (typeof event.stopPropagation === 'function') && event.stopPropagation(); (typeof event.cancelBubble === 'function') && event.cancelBubble(); } function enablePointerEvents(el) {  if (!el) return; el.style.pointerEvents='auto'; el.style.webkitTouchCallout='default'; el.style.webkitUserSelect='auto'; el.style.MozUserSelect='auto'; el.style.msUserSelect='auto'; el.style.userSelect='auto'; enablePointerEvents(el.parentElement); } enableContextMenu();

(~~a == a) where a is the string.

The difference is that ActionEvent is fired when the action is performed on the JCheckBox that is its state is changed either by clicking on it with the mouse or with a space bar or a mnemonic. It does not really listen to change events whether the JCheckBox is selected or deselected.

For instance, if JCheckBox c1 (say) is added to a ButtonGroup. Changing the state of other JCheckBoxes in the ButtonGroup will not fire an ActionEvent on other JCheckBox, instead an ItemEvent is fired.

Final words: An ItemEvent is fired even when the user deselects a check box by selecting another JCheckBox (when in a ButtonGroup), however ActionEvent is not generated like that instead ActionEvent only listens whether an action is performed on the JCheckBox (to which the ActionListener is registered only) or not. It does not know about ButtonGroup and all other selection/deselection stuff.

Now you can use nameof:

public static void Output<T>(IEnumerable<T> dataSource) where T : class
{
    string dataSourceName = typeof(T).Name;
    switch (dataSourceName)
    {
        case nameof(CustomerDetails):
            var t = 123;
            break;
        default:
            Console.WriteLine("Test");
    }
}

nameof(CustomerDetails) is basically identical to the string literal "CustomerDetails", but with a compile-time check that it refers to some symbol (to prevent a typo).

nameof appeared in C# 6.0, so after this question was asked.

The difference between include() and require() arises when the file being included cannot be found: include() will release a warning (E_WARNING) and the script will continue, whereas require() will release a fatal error (E_COMPILE_ERROR) and terminate the script. If the file being included is critical to the rest of the script running correctly then you need to use require().

Another way to solve this using xpath

WebDriver driver =  new FirefoxDriver();
driver.get("https://www.facebook.com/");
driver.manage().timeouts().implicitlyWait(15, TimeUnit.SECONDS);
driver.findElement(By.xpath(//*[@id='email'])).sendKeys("[email protected]");

Hope that will help. :)

With push you can even add multiple objects to an array

  let myArray = [];

   myArray.push(
              {name:"James", dataType:TYPES.VarChar, Value: body.Name},
              {name:"Boo", dataType:TYPES.VarChar, Value: body.Name},
              {name:"Alina", dataType:TYPES.VarChar, Value: body.Name}
             );

Try the following:

print "First is: %f" % (first)
print "Second is: %f" % (second)

I am unsure what answer is. But apart from that, this will be:

print "DONE: %f DIVIDED BY %f EQUALS %f, SWEET MATH BRO!" % (first, second, ans)

There's a lot of text on Format String Specifiers. You can google it and get a list of specifiers. One thing I forgot to note:

If you try this:

print "First is: %s" % (first)

It converts the float value in first to a string. So that would work as well.

While @Edward van Kuik's answer is correct, it doesn't take into account an issue with virtualenv v1.7 and above.

In particular installing python-mysqldb via apt on Ubuntu put it under /usr/lib/pythonX.Y/dist-packages, but this path isn't included by default in the virtualenv's sys.path.

So to resolve this, you should create your virtualenv with system packages by running something like:

virtualenv --system-site-packages .venv

Note that for this particular application there's a standard library function, android.text.format.DateUtils.getRelativeTimeSpanString().

request.getSession(true) and request.getSession() both do the same thing, but if we use request.getSession(false) it will return null if session object not created yet.

body * { line-height: 127%; }
p:after { content: "\A "; display: block; white-space: pre; }

https://www.w3.org/TR/CSS2/generate.html#x18 The Content Proerty, "newlines"... p will not add margin nor padding at end of p inside parent block (e.g., body › section › p). "\A " line break forces line space, equivalent styled line-height.

So, after update I had the same issue. I was using PEM key_file without extension and simply adding .pem fixed my issue. Now the file is key_file.pem.
