To attempt command line arguments directly is not possible.

One alternative might be environment variables (https://superuser.com/questions/728951/systemd-giving-my-service-multiple-arguments).

This is where I found the answer: http://www.freedesktop.org/software/systemd/man/systemctl.html

so sudo systemctl restart myprog -v -- systemctl will think you're trying to set one of its flags, not myprog's flag.

sudo systemctl restart myprog someotheroption -- systemctl will restart myprog and the someotheroption service, if it exists.

Simpler is better IMO!

Why don't you do this?

public class CourseController : JsonController
{
    public ActionResult ManageCoursesModel()
    {
        return JsonContent(<somedata>);
    }
}

The simple base class controller

public class JsonController : BaseController
{
    protected ContentResult JsonContent(Object data)
    {
        return new ContentResult
        {
            ContentType = "application/json",
             Content = JsonConvert.SerializeObject(data, new JsonSerializerSettings { 
              ContractResolver = new CamelCasePropertyNamesContractResolver() }),
            ContentEncoding = Encoding.UTF8
        };
    }
}

To copy a list you can use list(a) or a[:]. In both cases a new object is created.
These two methods, however, have limitations with collections of mutable objects as inner objects keep their references intact:

>>> a = [[1,2],[3],[4]]

>>> b = a[:]
>>> c = list(a)

>>> c[0].append(9)

>>> a
[[1, 2, 9], [3], [4]]
>>> c
[[1, 2, 9], [3], [4]]
>>> b
[[1, 2, 9], [3], [4]]
>>> 

If you want a full copy of your objects you need copy.deepcopy

>>> from copy import deepcopy
>>> a = [[1,2],[3],[4]]

>>> b = a[:]
>>> c = deepcopy(a)

>>> c[0].append(9)

>>> a
[[1, 2], [3], [4]]
>>> b
[[1, 2], [3], [4]]
>>> c
[[1, 2, 9], [3], [4]]
>>> 

Put your code in a method.

Try this:

public class MyClass {
    public static void main(String[] args) {
        UserInput input = new UserInput();
        input.name();
    }
}

Then "run" the class from your IDE

Try .replace(/ /g,"_");

Edit: or .split(' ').join('_') if you have an aversion to REs

Edit: John Resig said:

If you're searching and replacing through a string with a static search and a static replace it's faster to perform the action with .split("match").join("replace") - which seems counter-intuitive but it manages to work that way in most modern browsers. (There are changes going in place to grossly improve the performance of .replace(/match/g, "replace") in the next version of Firefox - so the previous statement won't be the case for long.)

string input = Console.ReadLine();
double d;
if (!Double.TryParse(input, out d))
    Console.WriteLine("Wrong input");
double r = d * Math.Pi;
Console.WriteLine(r);

The main reason of different input/output you're facing is that Console.Read() returns char code, not a number you typed! Learn how to use MSDN.

Another solution, very light with high performance with payload large:

Android Asynchronous Http Client library: http://loopj.com/android-async-http/

private static AsyncHttpClient client = new AsyncHttpClient();

private void uploadFileExecute(File file) {

    RequestParams params = new RequestParams();

    try { params.put("photo", file); } catch (FileNotFoundException e) {}

    client.post(getUrl(), params,

        new AsyncHttpResponseHandler() {

            public void onSuccess(String result) {

                Log.d(TAG,"uploadFile response: "+result);

            };

            public void onFailure(Throwable arg0, String errorMsg) {

                Log.d(TAG,"uploadFile ERROR!");

            };

        }

    );

}

This rule

main: producer.o consumer.o AddRemove.o
   $(COMPILER) -pthread $(CCFLAGS) -o producer.o consumer.o AddRemove.o

is wrong. It says to create a file named producer.o (with -o producer.o), but you want to create a file named main. Please excuse the shouting, but ALWAYS USE $@ TO REFERENCE THE TARGET:

main: producer.o consumer.o AddRemove.o
   $(COMPILER) -pthread $(CCFLAGS) -o $@ producer.o consumer.o AddRemove.o

As Shahbaz rightly points out, the gmake professionals would also use $^ which expands to all the prerequisites in the rule. In general, if you find yourself repeating a string or name, you're doing it wrong and should use a variable, whether one of the built-ins or one you create.

main: producer.o consumer.o AddRemove.o
   $(COMPILER) -pthread $(CCFLAGS) -o $@ $^

Download HAXM from SDK Manager

Open your SDK Manager from Android Studio, click the icon shown in the screen shot.

Click on "Launch Standalone SDK Manager" on the "Default Settings" Dialog.

Check node "Extras > Intel x86 Emulator Accelerator (HAXM installer)" and proceed with HAXM download.

Installing or Modifying HAXM

You can now access with installation (or modifying existing installtino) of HAXM by accessing the download location. Enter this path in "run"

%localappdata%\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager

and double click the file "intelhaxm-android.exe"

You can increase the size of memory allocated to HAXM while modifying existing HAXM install. I have a machine with 32 GB of RAM and would like to launch multiple AVDs at same time (for automated testing etc.) so I have allocated 8 GB to HAXM.

Caveat

If you are running one AVD of one 1 GB and allocated 2 GB to HAXM, you cannot run another AVD with RAM more than 1 GB. Please make sure that Android Device Monitor is not running when you are modifying or installing HAXM (just to avoid any suprises).

These steps are tested on Windows platform, but generally could be applied to other platforms too with slight modification.

You can use the new request method getSchemeAndHttpHost():

{{ app.request.getSchemeAndHttpHost() }}

Just another way of doing it should you require to do it over a larger range of columns

using applymap

df[['var1','var2']] = df[['var1','var2']].applymap("{0:.2f}".format)
df['var3'] = df['var3'].applymap(lambda x: "{0:.2f}%".format(x*100))

applymap is useful if you need to apply the function over multiple columns; it's essentially an abbreviation of the below for this specific example:

df[['var1','var2']].apply(lambda x: map(lambda x:'{:.2f}%'.format(x),x),axis=1)

Great explanation below of apply, map applymap:

Difference between map, applymap and apply methods in Pandas

Consecutive string literals are joined by the compiler, and parenthesized expressions are considered to be a single line of code:

logger.info("Skipping {0} because it's thumbnail was "
  "already in our system as {1}.".format(line[indexes['url']],
  video.title))

The only thing that worked for me is..

margin: 0 auto

If you wanna have everything into one only piece of code, then you can mix tim's answer with the example's approach found on the API for JTextField, and you'll get something like this:

public class JTextFieldLimit extends JTextField {
    private int limit;

    public JTextFieldLimit(int limit) {
        super();
        this.limit = limit;
    }

    @Override
    protected Document createDefaultModel() {
        return new LimitDocument();
    }

    private class LimitDocument extends PlainDocument {

        @Override
        public void insertString( int offset, String  str, AttributeSet attr ) throws BadLocationException {
            if (str == null) return;

            if ((getLength() + str.length()) <= limit) {
                super.insertString(offset, str, attr);
            }
        }       

    }

}

Then there is no need to add a Document to the JTextFieldLimit due to JTextFieldLimit already have the functionality inside.

You can copy all contents of myhtml to String as follows:

Scanner myScanner = null;
try
{
    myScanner = new Scanner(myhtml);
    String contents = myScanner.useDelimiter("\\Z").next(); 
}
finally
{
    if(myScanner != null)
    {
        myScanner.close(); 
    }
}

Ofcourse, you can add a catch block to handle exceptions properly.

Testing this Javascript:

var arr = [1234563995.721, 12345691212.718, 1234568421.5891, 12345677093.49284];

var sum = 0;
for( var i = 0; i < arr.length; i++ ) {
    sum += arr[i];
}

alert( "fMath(sum) = " + Math.round( sum * 1e12 ) / 1e12 );
alert( "fFixed(sum) = " + sum.toFixed( 5 ) );

Conclusion

Dont use Math.round( (## + ## + ... + ##) * 1e12) / 1e12

Instead, use ( ## + ## + ... + ##).toFixed(5) )

In IE 9, toFixed works very well.

If you are using Java 6 or higher you can use wildcards of this form:

java -classpath ".;c:\mylibs\*;c:\extlibs\*" MyApp

If you would like to add all subdirectories: lib\a\, lib\b\, lib\c\, there is no mechanism for this in except:

java -classpath ".;c:\lib\a\*;c:\lib\b\*;c:\lib\c\*" MyApp

There is nothing like lib\*\* or lib\** wildcard for the kind of job you want to be done.

I found this question looking for solution about how to send post request from java client to Google Endpoints. Above answers, very likely correct, but not work in case of Google Endpoints.

Solution for Google Endpoints.

1. Request body must contains only JSON string, not name=value pair.

2. Content type header must be set to "application/json".

   post("http://localhost:8888/_ah/api/langapi/v1/createLanguage",
                      "{\"language\":\"russian\", \"description\":\"dsfsdfsdfsdfsd\"}");
   
   
   
   public static void post(String url, String json ) throws Exception{
     String charset = "UTF-8"; 
     URLConnection connection = new URL(url).openConnection();
     connection.setDoOutput(true); // Triggers POST.
     connection.setRequestProperty("Accept-Charset", charset);
     connection.setRequestProperty("Content-Type", "application/json;charset=" + charset);
   
     try (OutputStream output = connection.getOutputStream()) {
       output.write(json.getBytes(charset));
     }
   
     InputStream response = connection.getInputStream();
   }
   

   It sure can be done using HttpClient as well.

To sort in ascending order :

Collections.sort(lList);

And for reverse order :

Collections.reverse(lList);

.aspx uses a full lifecycle (Init, Load, PreRender) and can respond to button clicks etc.
An .ashx has just a single ProcessRequest method.

You can use (* wildcards) outside a case statement, too, if you use double brackets:

string='My string';

if [[ $string == *My* ]]
then
echo "It's there!";
fi

To read you should create an instance of ifsteam and not ofstream.

ifstream iusrfile;

You should open the file in read mode.

iusrfile.open("usrfile.txt", ifstream::in);

Also this statement is not correct.

cout<<iusrfile;

If you are trying to print the data you read from the file you should do:

cout<<usr;

You can read more about ifstream and its API here

A single-quoted string does not have variables within it interpreted. A double-quoted string does.

Also, a double-quoted string can contain apostrophes without backslashes, while a single-quoted string can contain unescaped quotation marks.

The single-quoted strings are faster at runtime because they do not need to be parsed.

MySQL has an undocumented syntax to sort nulls last. Place a minus sign (-) before the column name and switch the ASC to DESC:

SELECT * FROM tablename WHERE visible=1 ORDER BY -position DESC, id DESC

It is essentially the inverse of position DESC placing the NULL values last but otherwise the same as position ASC.

A good reference is here http://troels.arvin.dk/db/rdbms#select-order_by

I would suggest concat when dealing with 2 strings, and || when those strings are more than 2:

select concat(a,b)
  from dual

or

  select 'a'||'b'||'c'||'d'
        from dual

instead of starting MainActivity again via startActivity, call finish() instead in the other activities to get back to MainActivity... as MainActivity is already in stack

If you don't know that you will get an array of dictionaries or single dictionary in the response from server you need to check whether the result contains an array or not.
In my case always receiving an array of dictionaries except once. So, to handle that I used the below code for swift 3.

if let str = strDict["item"] as? Array<Any>

Here as? Array checks whether the obtained value is array (of dictionary items). In else case you can handle if it is single dictionary item which is not kept inside an array.

You can create folder using the following Java code:

File dir = new File("nameoffolder");
dir.mkdir();

By executing above you will have folder 'nameoffolder' in current folder.

In my opinion, a dynamic PL/SQL block is somewhat obscure. While is very flexible, is also hard to tune, hard to debug and hard to figure out what's up. My vote goes to your first option,

EXECUTE IMMEDIATE v_query_str INTO v_num_of_employees USING p_job;

Both uses bind variables, but first, for me, is more redeable and tuneable than @jonearles option.

I suggest to use

#selector {
    text-transform: capitalize;
}

or

#selector::first-letter {
    text-transform: uppercase;
}

By the way, check this w3schools link: http://www.w3schools.com/cssref/pr_text_text-transform.asp

Yes you have the syntax error. If you want to get your Javascript errors and printing statements in your logcat you must implement the onConsoleMessage(ConsoleMessage cm) method in your WebChromeClient. It gives the complete stack traces like Web console(Inspect element). Here is the method.

public boolean onConsoleMessage(ConsoleMessage cm) 
    {
        Log.d("Message", cm.message() + " -- From line "
                             + cm.lineNumber() + " of "
                             + cm.sourceId() );
        return true;
    }

After implementation you will get your Javascript errors and print statements (console.log) on your logcat.

Easy.

Boom. done.

Most people need to change two values when trying to correctly forge the from address on an email. First is the from address and the second is the orig-to address. Many of the solutions offered online only change one of these values.

If as root, I try a simple mail command to send myself an email it might look like this. echo "test" | mail -s "a test" [email protected]

And the associated logs: Feb 6 09:02:51 myserver postfix/qmgr[28875]: B10322269D: from=<[email protected]>, size=437, nrcpt=1 (queue active) Feb 6 09:02:52 myserver postfix/smtp[19848]: B10322269D: to=<[email protected]>, relay=myMTA[x.x.x.x]:25, delay=0.34, delays=0.1/0/0.11/0.13, dsn=2.0.0, status=sent (250 Ok 0000014b5f678593-a0e399ef-a801-4655-ad6b-19864a220f38-000000)

Trying to change the from address with -- echo "test" | mail -s "a test" [email protected] -- [email protected]

This changes the orig-to value but not the from value: Feb 6 09:09:09 myserver postfix/qmgr[28875]: 6BD362269D: from=<[email protected]>, size=474, nrcpt=2 (queue active) Feb 6 09:09:09 myserver postfix/smtp[20505]: 6BD362269D: to=<me@noone>, orig_to=<[email protected]>, relay=myMTA[x.x.x.x]:25, delay=0.31, delays=0.06/0/0.09/0.15, dsn=2.0.0, status=sent (250 Ok 0000014b5f6d48e2-a98b70be-fb02-44e0-8eb3-e4f5b1820265-000000)

Next trying it with a -r and a -- to adjust the from and orig-to. echo "test" | mail -s "a test" -r [email protected] [email protected] -- [email protected]

And the logs: Feb 6 09:17:11 myserver postfix/qmgr[28875]: E3B972264C: from=<[email protected]>, size=459, nrcpt=2 (queue active) Feb 6 09:17:11 myserver postfix/smtp[21559]: E3B972264C: to=<[email protected]>, orig_to=<[email protected]>, relay=myMTA[x.x.x.x]:25, delay=1.1, delays=0.56/0.24/0.11/0.17, dsn=2.0.0, status=sent (250 Ok 0000014b5f74a2c0-c06709f0-4e8d-4d7e-9abf-dbcea2bee2ea-000000)

This is how it's working for me. Hope this helps someone.

That you can do, but I think you should not break the normal flow of activity. If you want to finish you activity then you can simply send a broadcast from your activity B to activity A.

Create a broadcast receiver before starting your activity B:

BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {

    @Override
    public void onReceive(Context arg0, Intent intent) {
        String action = intent.getAction();
        if (action.equals("finish_activity")) {
            finish();
            // DO WHATEVER YOU WANT.
        }
    }
};
registerReceiver(broadcastReceiver, new IntentFilter("finish_activity"));

Send broadcast from activity B to activity A when you want to finish activity A from B

Intent intent = new Intent("finish_activity");
sendBroadcast(intent);

I hope it will work for you...

Did you include a reference to System.Web.Extensions? If you click on your first link it says which assembly it's in.

Right Click the form you want to hide them on, choose Controls -> Properties.

In Properties, set

• Control Box -> False
• Minimize Box -> False
• Maximize Box -> False

You'll do this in the designer.

(Update: If I could delete this answer I would, although since it's accepted, I can't. I'm updating the description to provide better guidance and discourage folks from using the poor practice I outlined in the original answer).

You can specify these parameters via context or environment parameters, such as in context.xml. See the sections titled "Context Parameters" and "Environment Entries" on this page:

http://tomcat.apache.org/tomcat-5.5-doc/config/context.html

As @netjeff points out, these values will be available via the Context.lookup(String) method and not as System parameters.

Another way to do specify these values is to define variables inside of the web.xml file of the web application you're deploying (see below). As @Roberto Lo Giacco points out, this is generally considered a poor practice since a deployed artifact should not be environment specific. However, below is the configuration snippet if you really want to do this:

<env-entry>
    <env-entry-name>SMTP_PASSWORD</env-entry-name>
    <env-entry-type>java.lang.String</env-entry-type>
    <env-entry-value>abc123ftw</env-entry-value>
</env-entry>

I had a similar problem which I solved by changing the Port Settings in the port driver (located in Ports in device manager) to fit the device I was using.

For me it was that wrong Bits per second value was set.

Just had a simple variant problem... Convert files of typed .flv to .mp3 (yawn).

for file in read `find . *.flv`; do ffmpeg -i ${file} -acodec copy ${file}.mp3;done

recursively find all the Macintosh user flash files and turn them into audio (copy, no transcode) ... it's like the while above, noting that read instead of just 'for file in ' will escape.

Email headers don't matter to the smtp server. Just add the CC and BCC recipients to the toaddrs when you send your email. For CC, add them to the CC header.

toaddr = '[email protected]'
cc = ['[email protected]','[email protected]']
bcc = ['[email protected]']
fromaddr = '[email protected]'
message_subject = "disturbance in sector 7"
message_text = "Three are dead in an attack in the sewers below sector 7."
message = "From: %s\r\n" % fromaddr
        + "To: %s\r\n" % toaddr
        + "CC: %s\r\n" % ",".join(cc)
        + "Subject: %s\r\n" % message_subject
        + "\r\n" 
        + message_text
toaddrs = [toaddr] + cc + bcc
server = smtplib.SMTP('smtp.sunnydale.k12.ca.us')
server.set_debuglevel(1)
server.sendmail(fromaddr, toaddrs, message)
server.quit()

You can stringfy and count tokens:

int countArgs(char *args)
{
  int result = 0;
  int i = 0;

  while(isspace(args[i])) ++i;
  if(args[i]) ++result;

  while(args[i]) {
    if(args[i]==',') ++result;
    else if(args[i]=='\'') i+=2;
    else if(args[i]=='\"') {
      while(args[i]) {
        if(args[i+1]=='\"' && args[i]!='\\') {
          ++i;
          break;
        }
        ++i;
      }
    }
    ++i;
  }

  return result;
}

#define MACRO(...) \
{ \
  int count = countArgs(#__VA_ARGS__); \
  printf("NUM ARGS: %d\n",count); \
}

Hashing is the key. I think use lookup table and hashing key for this. You can find many hashing function online.

Option 1 is to use display:table-cell. You need to unfloat the Bootstrap col-* using float:none..

.center {
    display:table-cell;
    vertical-align:middle;
    float:none;
}

http://bootply.com/94394

Option 2 is display:flex to vertical align the row with flexbox:

.row.center {
   display: flex;
   align-items: center;
}

http://www.bootply.com/7rAuLpMCwr

Vertical centering is very different in Bootstrap 4. See this answer for Bootstrap 4 https://stackoverflow.com/a/41464397/171456

I had a similar issue where I wanted to represent HTML as JSON in the following way:

• For HTML text nodes, use a string
• For HTML elements, use an array with:
  • The (tag) name of the element
  • An object, mapping attribute keys to attribute values
  • The (inlined) list of children nodes

Example:

<div>
  <span>text</span>Text2
</div>

becomes

[
   'div',
   {},
   ['span', {}, 'text'],
   'Text2'
]

I wrote a function which handles transforming a DOM Element into this kind of JS structure. You can find this function at the end of this answer. The function is written in Typescript. You can use the Typescript playground to convert it to clean JavaScript.

Furthermore, if you need to parse an html string into DOM, assign to .innerHtml:

let element = document.createElement('div')
element.innerHtml = htmlString

Also, this one is common knowledge but if you need a JSON string output, use JSON.stringify.

/**
 * A NodeDescriptor stands for either an (HTML) Element, or for a text node
 */
export type NodeDescriptor = ElementDescriptor | string

/**
 * Array representing an HTML Element. It consists of:
 *
 * - The (tag) name of the element
 * - An object, mapping attribute keys to attribute values
 * - The (inlined) list of children nodes
 */
export type ElementDescriptor = [
   string,
   Record<string, string>,
   ...NodeDescriptor[]
]

export let htmlToJs = (element: Element, trim = true): ElementDescriptor => {
   let convertElement = (element: Element): ElementDescriptor => {
      let attributeObject: Record<string, string> = {}
      for (let { name, value } of element.attributes) {
         attributeObject[name] = value
      }

      let childArray: NodeDescriptor[] = []
      for (let node of element.childNodes) {
         let converter = htmlToJsDispatch[node.nodeType]
         if (converter) {
            let descriptor = converter(node as any)
            let skip = false

            if (trim && typeof descriptor === 'string') {
               descriptor = descriptor.trim()
               if (descriptor === '') skip = true
            }

            if (!skip) childArray.push(descriptor)
         }
      }

      return [element.tagName.toLowerCase(), attributeObject, ...childArray]
   }

   let htmlToJsDispatch = {
      [element.ELEMENT_NODE]: convertElement,
      [element.TEXT_NODE]: (node: Text): string => node.data,
   }

   return convertElement(element)
}

Officially not.

But here's a patch: http://rt.openssl.org/Ticket/Display.html?id=2651&user=guest&pass=guest

There are multiple ways to open a link in new tab in using Selenium WebDriver.

This create you an empty POST on PHP

But, this will work

Actually, you can save you picture at any place. If you want to save in a public space, so any other application can access, use this code:

storageDir = new File(
    Environment.getExternalStoragePublicDirectory(
        Environment.DIRECTORY_PICTURES
    ), 
    getAlbumName()
);

The picture doesn't go to the album. To do this, you need to call a scan:

private void galleryAddPic() {
    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    File f = new File(mCurrentPhotoPath);
    Uri contentUri = Uri.fromFile(f);
    mediaScanIntent.setData(contentUri);
    this.sendBroadcast(mediaScanIntent);
}

window.location.href = "/somewhere/else";

what language is this? If you're using a language that passes everything by reference like Java (except for native types), typically you can call .clone() method. The .clone() method is typically implemented by copying/cloning all relevant instance fields into the new object.

Here's an easy way without ifelse:

(a/sum(a))^(a>0)

An example:

a <- c(0, 1, 0, 0, 1, 1, 0, 1)

(a/sum(a))^(a>0)

[1] 1.00 0.25 1.00 1.00 0.25 0.25 1.00 0.25

var elm = document.createElement("div");
var jelm = $(elm);//convert to jQuery Element
var htmlElm = jelm[0];//convert to HTML Element

Push object into your array. Try this:

export class FormComponent implements OnInit {
    name: string;
    empoloyeeID : number;
    empList: Array<{name: string, empoloyeeID: number}> = []; 
    constructor() {}
    ngOnInit() {}
    onEmpCreate(){
        console.log(this.name,this.empoloyeeID);
        this.empList.push({ name: this.name, empoloyeeID: this.empoloyeeID });
        this.name = "";
        this.empoloyeeID = 0;
    }
}

Above code has been deprecated in API level 30. Now you can get using following code

 val width = windowManager.currentWindowMetrics.bounds.width()
 val height = windowManager.currentWindowMetrics.bounds.height()

This method reports the window size including all system bar areas, while Display#getSize(Point) reports the area excluding navigation bars and display cutout areas. The value reported by Display#getSize(Point) can be obtained by using:

 val metrics = windowManager.currentWindowMetrics
 // Gets all excluding insets
 val windowInsets = metrics.windowInsets
 var insets: Insets = windowInsets.getInsets(WindowInsets.Type.navigationBars())
 val cutout = windowInsets.displayCutout
 if (cutout != null) {
    val cutoutSafeInsets = Insets.of(cutout.safeInsetLeft, cutout.safeInsetTop, cutout.safeInsetRight, cutout.safeInsetBottom)
    insets = Insets.max(insets, cutoutSafeInsets)
 }

 val insetsWidth = insets.right + insets.left
 val insetsHeight = insets.top + insets.bottom

 // Legacy size that Display#getSize reports
 val legacySize =  Size(metrics.bounds.width() - insetsWidth, metrics.bounds.height() - insetsHeight)

A co-worker and I have just released a new GitHub project that supplies an Angular directive that you can use to decorate your table with fixed headers: https://github.com/objectcomputing/FixedHeader

It relies on css and angular only, with a directive that adds some divs. There is no jQuery required.

This implementation isn't as fully-featured as some other implementations, but if your need is simply to add fixed tables, we think this might be a good option.

Have a look at this Stack Overflow answer.

 function getParameterByName(name, url) {
     if (!url) url = window.location.href;
     name = name.replace(/[\[\]]/g, "\\$&");
     var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),
         results = regex.exec(url);
     if (!results) return null;
     if (!results[2]) return '';
     return decodeURIComponent(results[2].replace(/\+/g, " "));
 }

You can use the method to animate:

I.e.:

var thequerystring = getParameterByName("location");
$('html,body').animate({scrollTop: $("div#" + thequerystring).offset().top}, 500);

The trick with img::after is a good stuff, but has at least 2 downsides:

1. not supported by all browsers (e.g. doesn't work on Edge https://codepen.io/dsheiko/pen/VgYErm)
2. you cannot simply hide the image, you cover it - so not that helpful when you what to show a default image in the case

I do not know an universal solution without JavaScript, but for Firefox only there is a nice one:

img:-moz-broken{
  opacity: 0;
}

A "sort merge" join is performed by sorting the two data sets to be joined according to the join keys and then merging them together. The merge is very cheap, but the sort can be prohibitively expensive especially if the sort spills to disk. The cost of the sort can be lowered if one of the data sets can be accessed in sorted order via an index, although accessing a high proportion of blocks of a table via an index scan can also be very expensive in comparison to a full table scan.

A hash join is performed by hashing one data set into memory based on join columns and reading the other one and probing the hash table for matches. The hash join is very low cost when the hash table can be held entirely in memory, with the total cost amounting to very little more than the cost of reading the data sets. The cost rises if the hash table has to be spilled to disk in a one-pass sort, and rises considerably for a multipass sort.

(In pre-10g, outer joins from a large to a small table were problematic performance-wise, as the optimiser could not resolve the need to access the smaller table first for a hash join, but the larger table first for an outer join. Consequently hash joins were not available in this situation).

The cost of a hash join can be reduced by partitioning both tables on the join key(s). This allows the optimiser to infer that rows from a partition in one table will only find a match in a particular partition of the other table, and for tables having n partitions the hash join is executed as n independent hash joins. This has the following effects:

1. The size of each hash table is reduced, hence reducing the maximum amount of memory required and potentially removing the need for the operation to require temporary disk space.
2. For parallel query operations the amount of inter-process messaging is vastly reduced, reducing CPU usage and improving performance, as each hash join can be performed by one pair of PQ processes.
3. For non-parallel query operations the memory requirement is reduced by a factor of n, and the first rows are projected from the query earlier.

You should note that hash joins can only be used for equi-joins, but merge joins are more flexible.

In general, if you are joining large amounts of data in an equi-join then a hash join is going to be a better bet.

This topic is very well covered in the documentation.

You cannot call a non-static method from the main without instance creation, whereas you can simply call a static method. The main logic behind this is that, whenever you execute a .class file all the static data gets stored in the RAM and however, JVM(java virtual machine) would be creating context of the mentioned class which contains all the static data of the class. Therefore, it is easy to access the static data from the class without instance creation.The object contains the non-static data Context is created only once, whereas object can be created any number of times. context contains methods, variables etc. Whereas, object contains only data. thus, the an object can access both static and non-static data from the context of the class

Try instead of db.parse(xml):

Document doc = db.parse(new InputSource(new StringReader(**xml**)));

When using numbers as the key, I suppose you could also try this:

        Map<Long, String> map = new HashMap<>();
        map.put(4L, "The First");
        map.put(6L, "The Second");
        map.put(11L, "The Last");

        long lastKey = 0;
        //you entered Map<Long, String> entry
        for (Map.Entry<Long, String> entry : map.entrySet()) {
            lastKey = entry.getKey();
        }
        System.out.println(lastKey); // 11

The line (or lines) between the lines beginning <<<<<<< and ====== here:

<<<<<<< HEAD:file.txt
Hello world
=======

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

You are experiencing two separate problems here:

hduser@ubuntu:/usr/local/hadoop$ hadoop fs -put /usr/local/input-data/ /input put: /usr/local/input-data (Permission denied)

Here, the user hduser does not have access to the local directory /usr/local/input-data. That is, your local permissions are too restrictive. You should change it.

hduser@ubuntu:/usr/local/hadoop$ sudo bin/hadoop fs -put /usr/local/input-data/ /inwe put: org.apache.hadoop.security.AccessControlException: Permission denied: user=root, access=WRITE, inode="":hduser:supergroup:rwxr-xr-x

Here, the user root (since you are using sudo) does not have access to the HDFS directory /input. As you can see: hduser:supergroup:rwxr-xr-x says only hduser has write access. Hadoop doesn't really respect root as a special user.

To fix this, I suggest you change the permissions on the local data:

sudo chmod -R og+rx /usr/local/input-data/

Then, try the put command again as hduser.

set your CssClass property in textbox1 to "cupper", then in page content create new css class :

new Test():

1. create new Object() obj
2. set obj.__proto__ to Test.prototype
3. return Test.call(obj) || obj; // normally obj is returned but constructors in JS can return a value

Object.create( Test.prototype )

1. create new Object() obj
2. set obj.__proto__ to Test.prototype
3. return obj;

So basically Object.create doesn't execute the constructor.

According to @Abhishek Singh's you need to understand the problem:

What is the line which gives exception ?? The reason for this is because the element to which you have referred is removed from the DOM structure

and you can not refer to it anymore (imagine what element's ID has changed).

Follow the code:

class TogglingPage {
  @FindBy(...)
  private WebElement btnTurnOff;

  @FindBy(...)
  private WebElement btnTurnOn;

  TogglingPage turnOff() {
    this.btnTurnOff.isDisplayed();  
    this.btnTurnOff.click();          // when clicked, button should swap into btnTurnOn
    this.btnTurnOn.isDisplayed();
    this.btnTurnOn.click();           // when clicked, button should swap into btnTurnOff
    this.btnTurnOff.isDisplayed();    // throws an exception
    return new TogglingPage();
  }
}

Now, let us wonder why?

1. btnTurnOff was found by a driver - ok
2. btnTurnOff was replaced by btnTurnOn - ok
3. btnTurnOn was found by a driver. - ok
4. btnTurnOn was replaced by btnTurnOff - ok
5. we call this.btnTurnOff.isDisplayed(); on the element which does not exist anymore in Selenium sense - you can see it, it works perfectly, but it is a different instance of the same button.

Possible fix:

  TogglingPage turnOff() {
    this.btnTurnOff.isDisplayed();  
    this.btnTurnOff.click();

    TogglingPage newPage = new TogglingPage();
    newPage.btnTurnOn.isDisplayed();
    newPage.btnTurnOn.click();

    TogglingPage newerPage = new TogglingPage();
    newerPage.btnTurnOff.isDisplayed();    // ok
    return newerPage;
  }

no your ans is Wrong

Selection of Al and Ah is from AX not from EAX

e.g

EAX=0000 0000 0000 0000 0000 0000 0000 0111

So if we call AX it should return

0000 0000 0000 0111

if we call AH it should return

0000 0000

and when we call AL it should return

0000 0111

Example number 2

EAX: 22 33 55 77
AX: 55 77
AH: 55    
AL: 77

example 3

EAX: 1111 0000 0000 0000 0000 0000 0000 0111    
AX= 0000 0000 0000 0111
AH= 0000 0000
AL= 0000 0111  

Now there is few ways to install fontAwesome on Angular CLI:

ng add @fortawesome/angular-fontawesome

OR using yarn

yarn add @fortawesome/fontawesome-svg-core
yarn add @fortawesome/free-solid-svg-icons
yarn add @fortawesome/angular-fontawesome

OR Using NPM

npm install @fortawesome/fontawesome-svg-core
npm install @fortawesome/free-solid-svg-icons
npm install @fortawesome/angular-fontawesome

It's perfectly possible to template a class on an integer rather than a type. We can assign the templated value to a variable, or otherwise manipulate it in a way we might with any other integer literal:

unsigned int x = N;

In fact, we can create algorithms which evaluate at compile time (from Wikipedia):

template <int N>
struct Factorial 
{
     enum { value = N * Factorial<N - 1>::value };
};

template <>
struct Factorial<0> 
{
    enum { value = 1 };
};

// Factorial<4>::value == 24
// Factorial<0>::value == 1
void foo()
{
    int x = Factorial<4>::value; // == 24
    int y = Factorial<0>::value; // == 1
}

Python has a language feature called List Comprehensions that is perfectly suited to making this sort of thing extremely easy. The following statement does exactly what you want and stores the result in l3:

l3 = [x for x in l1 if x not in l2]

l3 will contain [1, 6].

I solved it changing my 'Compiler compliance level'. In Eclipse:

First of all print isn't a function in Python 2, it is a statement.

To suppress the automatic newline add a trailing ,(comma). Now a space will be used instead of a newline.

Demo:

print 1,
print 2

output:

1 2

Or use Python 3's print() function:

from __future__ import print_function
print(1, end=' ') # default value of `end` is '\n'
print(2)

As you can clearly see print() function is much more powerful as we can specify any string to be used as end rather a fixed space.

I modified the query to get the schema size per tablespace ..

SELECT owner,
     tablespace_name,
     TRUNC (SUM (bytes) / 1024 / 1024)   Meg,
     ROUND (ratio_to_report (SUM (bytes)) OVER () * 100) Percent
FROM (SELECT tablespace_name, owner, bytes
        FROM dba_segments
       WHERE segment_type IN
                 ('TABLE', 'TABLE PARTITION', 'TABLE SUBPARTITION')
      UNION ALL
      SELECT i.tablespace_name, i.owner, s.bytes
        FROM dba_indexes i, dba_segments s
       WHERE     s.segment_name = i.index_name
             AND s.owner = i.owner
             AND s.segment_type IN
                     ('INDEX', 'INDEX PARTITION', 'INDEX SUBPARTITION')
      UNION ALL
      SELECT l.tablespace_name, l.owner, s.bytes
        FROM dba_lobs l, dba_segments s
       WHERE     s.segment_name = l.segment_name
             AND s.owner = l.owner
             AND s.segment_type IN ('LOBSEGMENT', 'LOB PARTITION')
      UNION ALL
      SELECT l.tablespace_name, l.owner, s.bytes
        FROM dba_lobs l, dba_segments s
       WHERE     s.segment_name = l.index_name
             AND s.owner = l.owner
             AND s.segment_type = 'LOBINDEX')
WHERE owner IN UPPER ('&owner')
GROUP BY owner, tablespace_name
--HAVING SUM(bytes)/1024/1024 > 10  /* Ignore really small tables */
ORDER BY tablespace_name -- desc
;

Easiest way is use read only attribute to prevent direct user input:

 <input class="datepicker" type="text" name="date" value="" readonly />

Or you could use HTML5 validation based on pattern attribute. Date input pattern (dd/mm/yyyy or mm/dd/yyyy):

<input type="text" pattern="\d{1,2}/\d{1,2}/\d{4}" class="datepicker" name="date" value="" />

You can do something like this:

.flex {_x000D_
  display: flex;_x000D_
  flex-direction: row;_x000D_
  flex-wrap: wrap;_x000D_
}_x000D_
_x000D_
.flex>div {_x000D_
  flex: 1 0 50%;_x000D_
}_x000D_
_x000D_
.flex>div:first-child {_x000D_
  flex: 0 1 100%;_x000D_
}

<div class="flex">_x000D_
  <div>Hi</div>_x000D_
  <div>Hello</div>_x000D_
  <div>Hello 2</div>_x000D_
</div>

Here is a demo: http://jsfiddle.net/73574emn/1/

This model relies on the line-wrap after one "row" is full. Since we set the first item's flex-basis to be 100% it fills the first row completely. Special attention on the flex-wrap: wrap;

Change the line where you print the output to:

printf("\nmaximum of %d and %d is = %d",a,b,c);

See the docs here

As Johannes pointed out,

for c in "string":
    #do something with c

You can iterate pretty much anything in python using the for loop construct,

for example, open("file.txt") returns a file object (and opens the file), iterating over it iterates over lines in that file

with open(filename) as f:
    for line in f:
        # do something with line

If that seems like magic, well it kinda is, but the idea behind it is really simple.

There's a simple iterator protocol that can be applied to any kind of object to make the for loop work on it.

Simply implement an iterator that defines a next() method, and implement an __iter__ method on a class to make it iterable. (the __iter__ of course, should return an iterator object, that is, an object that defines next())

See official documentation

upstream defines a cluster that you can proxy requests to. It's commonly used for defining either a web server cluster for load balancing, or an app server cluster for routing / load balancing.

You are right, you are creating a matrix with 2 rows, 3 columns and 4 depth. Numpy prints matrixes different to Matlab:

However you are calculating the same matrix. Take a look to Numpy for Matlab users, it will guide you converting Matlab code to Numpy.

For example if you are using OpenCV, you can build an image using numpy taking into account that OpenCV uses BGR representation:

import cv2
import numpy as np

a = np.zeros((100, 100,3))
a[:,:,0] = 255

b = np.zeros((100, 100,3))
b[:,:,1] = 255

c = np.zeros((100, 200,3)) 
c[:,:,2] = 255

img = np.vstack((c, np.hstack((a, b))))

cv2.imshow('image', img)
cv2.waitKey(0)

If you take a look to matrix c you will see it is a 100x200x3 matrix which is exactly what it is shown in the image (in red as we have set the R coordinate to 255 and the other two remain at 0).

Honestly I don't see the point in doing superscript/subscript in CSS only. There's no handy CSS attribute for it, just a bunch of homegrown implementations including:

.superscript { position: relative; top: -0.5em; font-size: 80%; }

or using vertical-align or I'm sure other ways. Thing is, it starts to get complicated:

• CSS superscript spacing on line height;
• Beware CSS for Superscript/Subcript on why you arguably shouldn't style superscript/subscript with CSS at all;

The second point is worth emphasizing. Typically superscript/subscript is not actually a styling issue but is indicative of meaning.

Side note: It's worth mentioning this list of entities for common mathematical superscript and subscript expressions even though this question doesn't relate to that.

The sub/sup tags are in HTML and XHTML. I would just use those.

As for the rest of your CSS, the :after pseudo-element and content attributes are not widely supported. If you really don't want to put this manually in the HTML I think a Javascript-based solution is your next best bet. With jQuery this is as simple as:

$(function() {
  $("a.external").append("<sup>+</sup>");
};

I did basically the same thing that you did Adam, but with a slight modification to make sure I was appending to the head tag to get the job done. I simply created an include function (code below) to handle both script and css files.

This function also checks to make sure that the script or CSS file hasn't already been loaded dynamically. It does not check for hand coded values and there may have been a better way to do that, but it served the purpose.

function include( url, type ){
    // First make sure it hasn't been loaded by something else.
    if( Array.contains( includedFile, url ) )
        return;

    // Determine the MIME-type
    var jsExpr = new RegExp( "js$", "i" );
    var cssExpr = new RegExp( "css$", "i" );
    if( type == null )
        if( jsExpr.test( url ) )
            type = 'text/javascript';
        else if( cssExpr.test( url ) )
            type = 'text/css';

    // Create the appropriate element.
    var tag = null;
    switch( type ){
        case 'text/javascript' :
            tag = document.createElement( 'script' );
            tag.type = type;
            tag.src = url;
            break;
        case 'text/css' :
            tag = document.createElement( 'link' );
            tag.rel = 'stylesheet';
            tag.type = type;
            tag.href = url;
            break;
    }

    // Insert it to the <head> and the array to ensure it is not
    // loaded again.
    document.getElementsByTagName("head")[0].appendChild( tag );
    Array.add( includedFile, url );
}

Get second, third, fourth......Nth highest salary using following query

SELECT MIN(salary) from employees WHERE salary IN( SELECT TOP N salary FROM employees ORDER BY salary DESC)

Replace N by you number i.e. N=2 for second highest salary, N=3 for third highest salary and so on. So for second highest salary use

SELECT MIN(salary) from employees WHERE salary IN( SELECT TOP 2 salary FROM employees ORDER BY salary DESC)

What system are you using? Webpack? Vue-loader?

I'll only brainstorming here...

Because .png is not a JavaScript file, you will need to configure Webpack to use file-loader or url-loader to handle them. The project scaffolded with vue-cli has also configured this for you.

You can take a look at webpack.conf.js in order to see if it's well configured like

...
    {
        test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('img/[name].[hash:7].[ext]')
        }
      },
...

/assets is for files that are handles by webpack during bundling - for that, they have to be referenced somewhere in your javascript code.

Other assets can be put in /static, the content of this folder will be copied to /dist later as-is.

I recommend you to try to change:

iconUrl: './assets/img.png'

to

iconUrl: './dist/img.png'

You can read the official documentation here: https://vue-loader.vuejs.org/en/configurations/asset-url.html

Hope it helps to you!

final keyword in the method input parameter is not needed. Java creates a copy of the reference to the object, so putting final on it doesn't make the object final but just the reference, which doesn't make sense

This should do what you are looking for.. It assumes your list will always be just numbers. If that is not the case, just change the references to DBMS_SQL.NUMBER_TABLE to a table type that works for all of your data:

    BEGIN

        IF list_in is not null
        THEN
            /*
            || Use lengths loop through the list the correct amount of times,
            || and substr to get only the correct item for that row
            */
            FOR i in 1 .. length(list_in)-length(replace(list_in,delimiter_in,''))+1
            LOOP
                /*

                            instr(delimiter_in||list_in||delimiter_in, delimiter_in, 1, i  ) + 1,
                            instr (delimiter_in||list_in||delimiter_in, delimiter_in, 1, i+1) - instr (delimiter_in||list_in||delimiter_in, delimiter_in, 1, i) -1
                        );
            END LOOP;
        END IF;

        RETURN v_retval;

    END list_to_tbl;

   THEN
      raise_application_error(num => -20001, msg => 'Length of lists do not match');
   END IF;

   -- Bulk insert from collections
   FORALL i IN INDICES OF v_tbl1
      insert into tmp (a, b)
      values (v_tbl1(i), v_tbl2(i));

END insert_from_lists; 

The results of the test and source code are below (you can set the number of iterations in the app). The time is in milliseconds, and each entry is an average result of running the test 5-10 times. I found that generally it is accurate to 2-3 significant digits and after that it would vary with each run. That gives a margin of error of less than 1%. The test was running on an iPhone 3G as that's the target platform I was interested in.

The classes provided by Cocoa for handling data sets (NSDictionary, NSArray, NSSet etc.) provide a very nice interface for managing information, without having to worry about the bureaucracy of memory management, reallocation etc. Of course this does come at a cost though. I think it's pretty obvious that say using an NSArray of NSNumbers is going to be slower than a C Array of floats for simple iterations, so I decided to do some tests, and the results were pretty shocking! I wasn't expecting it to be this bad. Note: these tests are conducted on an iPhone 3G as that's the target platform I was interested in.

In this test I do a very simple random access performance comparison between a C float* and NSArray of NSNumbers

I create a simple loop to sum up the contents of each array and time them using mach_absolute_time(). The NSMutableArray takes on average 400 times longer!! (not 400 percent, just 400 times longer! thats 40,000% longer!).

////////////////////

Available since the introduction of blocks, this allows to iterate an array with blocks. Its syntax isn't as nice as fast enumeration, but there is one very interesting feature: concurrent enumeration. If enumeration order is not important and the jobs can be done in parallel without locking, this can provide a considerable speedup on a multi-core system. More about that in the concurrent enumeration section.

[myArray enumerateObjectsUsingBlock:^(id object, NSUInteger index, BOOL *stop) {
    [self doSomethingWith:object];
}];
[myArray enumerateObjectsWithOptions:NSEnumerationConcurrent usingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
    [self doSomethingWith:object];
}];

/////////// NSFastEnumerator

The idea behind fast enumeration is to use fast C array access to optimize iteration. Not only is it supposed to be faster than traditional NSEnumerator, but Objective-C 2.0 also provides a very concise syntax.

id object;
for (object in myArray) {
    [self doSomethingWith:object];
}

/////////////////

NSEnumerator

This is a form of external iteration: [myArray objectEnumerator] returns an object. This object has a method nextObject that we can call in a loop until it returns nil

NSEnumerator *enumerator = [myArray objectEnumerator];
id object;
while (object = [enumerator nextObject]) {
    [self doSomethingWith:object];
}

/////////////////

objectAtIndex: enumeration

Using a for loop which increases an integer and querying the object using [myArray objectAtIndex:index] is the most basic form of enumeration.

NSUInteger count = [myArray count];
for (NSUInteger index = 0; index < count ; index++) {
    [self doSomethingWith:[myArray objectAtIndex:index]];
}

////////////// From : darkdust.net

You could also use this:

$('.slider').slick({
   //other settings ................
   respondTo: 'slider', //makes the slider to change width depending on the container it is in
   adaptiveHeight: true //makes the height change depending on the height of the element inside
})

It's not a good coding to put PHP code into CSS

body
{
    background-image:url('bg.png');
}

that's it

Method 4 is my preferred method. The short circuit of the && operator makes the code the most readable. Method 3, Catching NullPointerException, is frowned upon most of the time when a simple null check would suffice.

Even more simple if you accept using pandas :

import pandas
result = {0: 1.1181753789488595, 1: 0.5566080288678394, 2: 0.4718269778030734, 3: 0.48716683119447185, 4: 1.0, 5: 0.1395076201641266, 6: 0.20941558441558442}
df = pandas.DataFrame(result, index=[0])
print df

gives :

          0         1         2         3  4         5         6
0  1.118175  0.556608  0.471827  0.487167  1  0.139508  0.209416

When doing a getObject() from the S3 API, per the docs the contents of your file are located in the Body property, which you can see from your sample output. You should have code that looks something like the following

const aws = require('aws-sdk');
const s3 = new aws.S3(); // Pass in opts to S3 if necessary

var getParams = {
    Bucket: 'abc', // your bucket name,
    Key: 'abc.txt' // path to the object you're looking for
}

s3.getObject(getParams, function(err, data) {
    // Handle any error and exit
    if (err)
        return err;

  // No error happened
  // Convert Body from a Buffer to a String

  let objectData = data.Body.toString('utf-8'); // Use the encoding necessary
});

You may not need to create a new buffer from the data.Body object but if you need you can use the sample above to achieve that.

From maven setting reference, you can not put your username/password in a pom.xml

The repositories for download and deployment are defined by the repositories and distributionManagement elements of the POM. However, certain settings such as username and password should not be distributed along with the pom.xml. This type of information should exist on the build server in the settings.xml.

You can first add a repository in your pom and then add the username/password in the $MAVEN_HOME/conf/settings.xml:

  <servers>
    <server>
        <id>my-internal-site</id>
        <username>yourUsername</username>
        <password>yourPassword</password>
    </server>
  </servers>

While I agree with Doug Hays' answer, I'll chime in here to say that the reason your code doesn't work is because strtotime() expects an INT as the 2nd argument, not a string (even one that represents a date)

If you turn on max error reporting you'll see this as a "A non well formed numeric value" error which is E_NOTICE level.

I have never considered it to be a bad practice to throw an exception in the constructor. When the class is designed, you have a certain idea in mind of what the structure for that class should be. If someone else has a different idea and tries to execute that idea, then you should error accordingly, giving the user feedback on what the error is. In your case, you might consider something like

if (age < 0) throw new NegativeAgeException("The person you attempted " +
                       "to construct must be given a positive age.");

where NegativeAgeException is an exception class that you constructed yourself, possibly extending another exception like IndexOutOfBoundsException or something similar.

Assertions don't exactly seem to be the way to go, either, since you're not trying to discover bugs in your code. I would say terminating with an exception is absolutely the right thing to do here.

Python3 + Using boto3 API approach.

By using S3.Client.download_fileobj API and Python file-like object, S3 Object content can be retrieved to memory.

Since the retrieved content is bytes, in order to convert to str, it need to be decoded.

import io
import boto3

client = boto3.client('s3')
bytes_buffer = io.BytesIO()
client.download_fileobj(Bucket=bucket_name, Key=object_key, Fileobj=bytes_buffer)
byte_value = bytes_buffer.getvalue()
str_value = byte_value.decode() #python3, default decoding is utf-8

On my Linux Mint 17.3 install, I found these instructions incredibly helpful.

The problem seems to boil down to the system's default Java being OpenJDK and Android Studio preferring Oracle's JDK. I actually did not perform the OpenJDK removal steps given in the tutorial, but only downloaded the Oracle JDK and set it as my system's default. Android Studio worked right away.

In case the linked page ever goes away, the steps I took were

Download Oracle JDK. Mine was version 1.7.0_79.

tar -zxvf jdk-7u79-linux-x64.tar.gz
sudo mkdir -p /opt/java
sudo mv jdk1.7.0_79 /opt/java
sudo update-alternatives --install "/usr/bin/java" "java" "/opt/java/jdk1.7.0_79/bin/java" 1
sudo update-alternatives --set java /opt/java/jdk1.7.0_25/bin/java

and

java -version

confirms the system is using Oracle's JDK, giving output like

java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)

From nullptr: A Type-safe and Clear-Cut Null Pointer:

The new C++09 nullptr keyword designates an rvalue constant that serves as a universal null pointer literal, replacing the buggy and weakly-typed literal 0 and the infamous NULL macro. nullptr thus puts an end to more than 30 years of embarrassment, ambiguity, and bugs. The following sections present the nullptr facility and show how it can remedy the ailments of NULL and 0.

You can use a static method in PrintReportController and then call it from the SubmitPerformanceController like this;

namespace App\Http\Controllers;

class PrintReportController extends Controller
{

    public static function getPrintReport()
    {
      return "Printing report";
    }


}



namespace App\Http\Controllers;

use App\Http\Controllers\PrintReportController;

class SubmitPerformanceController extends Controller
{


    public function index()
    {

     echo PrintReportController::getPrintReport();

    }

}

It was really hard to remember that

    int numberOfColumns = arr.length;
    int numberOfRows = arr[0].length;

Let's understand why this is so and how we can figure this out when we're given an array problem. From the below code we can see that rows = 4 and columns = 3:

    int[][] arr = { {1, 1, 1, 1}, 

                    {2, 2, 2, 2}, 

                    {3, 3, 3, 3} };

arr has multiple arrays in it, and these arrays can be arranged in a vertical manner to get the number of columns. To get the number of rows, we need to access the first array and consider its length. In this case, we access [1, 1, 1, 1] and thus, the number of rows = 4. When you're given a problem where you can't see the array, you can visualize the array as a rectangle with n X m dimensions and conclude that we can get the number of rows by accessing the first array then its length. The other one (arr.length) is for the columns.

If you need to handle the output of a command, see example: using Runtime.exec() in Java

Use this function which suits every situation.

CREATE FUNCTION dbo.fnNumPadLeft (@input INT, @pad tinyint)
RETURNS VARCHAR(250)
AS BEGIN
    DECLARE @NumStr VARCHAR(250)

    SET @NumStr = LTRIM(@input)

    IF(@pad > LEN(@NumStr))
        SET @NumStr = REPLICATE('0', @Pad - LEN(@NumStr)) + @NumStr;

    RETURN @NumStr;
END

Sample output

SELECT [dbo].[fnNumPadLeft] (2016,10) -- returns 0000002016
SELECT [dbo].[fnNumPadLeft] (2016,5) -- returns 02016
SELECT [dbo].[fnNumPadLeft] (2016,2) -- returns 2016
SELECT [dbo].[fnNumPadLeft] (2016,0) -- returns 2016 

xcopy /s/y J:\"My Name"\"FILES IN TRANSIT"\JOHN20101126\"Missing file"\Shapes.atc C:\"Documents and Settings"\"His name"\"Application Data"\Autodesk\"AutoCAD 2010"\"R18.0"\enu\Support\*.*"

..should do it.

Good idea to do an:

IF NOT EXIST "C:\Documents and Settings\His name\Application Data\Autodesk\AutoCAD 2010\R18.0\enu\Support\Shapes.atc" ECHO/ && ECHO/ && ECHO * * * * * COPY FAILED - Call JustME at 555-555-1212 && ECHO/ && pause

(assuming you've done a rename of previous version to .old)

XCOPY  /Z  <----- restartable mode - good for large files.

Simple its works me:)

YourArrayList_Object.clear();

She the list of stash

git stash list 
stash@{0}: WIP on feature/blabla: 830335224fa Name Commit
stash@{1}: WIP on feature/blabla2: 830335224fa Name Commit 2

So get the stash number and do:

You can do:

 git stash show -p stash@{1}

But if you want a diff (this is different to show the stash, that's why I write this answer. Diff consider the current code in your branch and show just show what you will apply)

You can use:

git diff stash@{0}

or

git diff stash@{0} <branch name>

Another interesting thing to do is:

git stash apply
git stash apply stash@{10}

This applies the stash without removing it from the list, you can git checkout . to remove those change or if you are happy git stash drop stash@{10} to remove a stash from the list.

From here I never recommend to use git stash pop and use a combination of git stash apply and git stash drop If you apply a stash in the wrong branch... well sometimes is difficult to recover your code.

What levi said about passing it into the constructor is correct, but you could also use an object.

I think what Veverke is trying to say is that you could easily use the delete keyword on an object to achieve the same effect.

I think you're confused by the terminology; properties are components of the object that you can use as named indices (if you want to think of it that way).

Try something like this:

var obj = {
    "bob": "dole",
    "mr.": "peabody",
    "darkwing": "duck"
};

Then, you could just do this:

delete obj["bob"];

The structure of the object would then be this:

{
    "mr.": "peabody",
    "darkwing": "duck"
}

Which has the same effect.

`n is a line feed character. Notepad (prior to Windows 10) expects linebreaks to be encoded as `r`n (carriage return + line feed, CR-LF). Open the file in some useful editor (SciTE, Notepad++, UltraEdit-32, Vim, ...) and convert the linebreaks to CR-LF. Or use PowerShell:

(Get-Content $logpath | Out-String) -replace "`n", "`r`n" | Out-File $logpath

Is that what you had in mind?

This is what Chris Sells tells about those statements in The C# Programming Language;

I sometimes forget that yield return is not the same as return , in that the code after a yield return can be executed. For example, the code after the first return here can never be executed:

int F() {
    return 1;
    return 2; // Can never be executed
}

In contrast, the code after the first yield return here can be executed:

IEnumerable<int> F() {
    yield return 1;
    yield return 2; // Can be executed
}

This often bites me in an if statement:

IEnumerable<int> F() {
    if(...) {
        yield return 1; // I mean this to be the only thing returned
    }
    yield return 2; // Oops!
}

In these cases, remembering that yield return is not “final” like return is helpful.

If your table is only 2 columns across, you can easily reach the second td with the adjacent sibling selector, which IE8 does support along with :first-child:

.editor td:first-child
{
    width: 150px; 
}

.editor td:first-child + td input,
.editor td:first-child + td textarea
{
    width: 500px;
    padding: 3px 5px 5px 5px;
    border: 1px solid #CCC; 
}

Otherwise, you'll have to use a JS selector library like jQuery, or manually add a class to the last td, as suggested by James Allardice.

What worked for me ( target: debug an windows server app running on localhost:99999 from an client app running on android phone )

1. phone and pc connected on the same network e.g. 192.168.1.xxx ( connected via wifi in my case)
2. enable port 99999 in windows firewall
3. run in cmd as administrator: netsh http add urlacl url=http://*:99999/ user=Everyone

then the service app url (my_dev_machine_ip:99999/path_to_service) was accessible from the phone.

This solution allows you to add space in-between the images as well. It combines the best parts of all the existing solutions and doesn't add any ugly table borders.

<p align="center">
  <img alt="Light" src="https://...light.png" width="45%">
&nbsp; &nbsp; &nbsp; &nbsp;
  <img alt="Dark" src="https://...dark.png" width="45%">
</p>

The key is adding the   non-breaking space HTML entities, which you can add and remove in order to customize the spacing.

You can see this example live on GitHub here.

You want the mod operator.

The expression a Mod b is equivalent to the following formula:

a - (b * (a \ b))

Edited to add:

There are some special cases you may have to consider, because Excel is using floating point math (and returns a float), which the VBA function returns an integer. Because of this, using mod with floating-point numbers may require extra attention:

• Excel's results may not correspond exactly with what you would predict; this is covered briefly here (see topmost answer) and at great length here.

• As @André points out in the comments, negative numbers may round in the opposite direction from what you expect. The Fix() function he suggests is explained here (MSDN).

According to the GNU make manual:

CFLAGS: Extra flags to give to the C compiler.
CXXFLAGS: Extra flags to give to the C++ compiler.
CPPFLAGS: Extra flags to give to the C preprocessor and programs that use it (the C and Fortran compilers).

note: PP stands for PreProcessor (and not Plus Plus), i.e.

CPP: Program for running the C preprocessor, with results to standard output; default ‘$(CC) -E’.

These variables are used by the implicit rules of make

I think the only foolproof method you can have is creating a Contact Me page that is a form that submits to a script that sends to your email address. That way, your address is never exposed to the public at all. This may be undesirable for some reason, but I think it's a pretty good solution. It often irks me when I'm forced to copy/paste someone's email address from their site to my mail client and send them a message; I'd rather do it right through a form on their site. Also, this approach allows you to have anonymous comments sent to you, etc. Just be sure to protect your form using some kind of anti-bot scheme, such as a captcha. There are plenty of them discussed here on SO.

I think that the object you received in your response payload isn't an array. Perhaps the array you want to iterate is contained into an attribute. You should check the structure of the received data...

You could try something like that:

getusers() {
  this.http.get(`https://api.github.com/search/users?q=${this.input1.value}`)
    .map(response => response.json().items) // <------
    .subscribe(
      data => this.users = data,
      error => console.log(error)
    );
}

Edit

Following the Github doc (developer.github.com/v3/search/#search-users), the format of the response is:

{
  "total_count": 12,
  "incomplete_results": false,
  "items": [
    {
      "login": "mojombo",
      "id": 1,
      (...)
      "type": "User",
      "score": 105.47857
    }
  ]
}

So the list of users is contained into the items field and you should use this:

getusers() {
  this.http.get(`https://api.github.com/search/users?q=${this.input1.value}`)
    .map(response => response.json().items) // <------
    .subscribe(
      data => this.users = data,
      error => console.log(error)
    );
}

Service: startservice can cause side affects,best way to use messenger and pass data.

private CallBackHandler mServiceHandler= new CallBackHandler(this);
private Messenger mServiceMessenger=null;
//flag with which the activity sends the data to service
private static final int DO_SOMETHING=1;

private static class CallBackHandler extends android.os.Handler {

private final WeakReference<Service> mService;

public CallBackHandler(Service service) {
    mService= new WeakReference<Service>(service);
}

public void handleMessage(Message msg) {
    //Log.d("CallBackHandler","Msg::"+msg);
    if(DO_SOMETHING==msg.arg1)
    mSoftKeyService.get().dosomthing()
}
}

Activity:Get Messenger from Intent fill it pass data and pass the message back to service

private Messenger mServiceMessenger;
@Override
protected void onCreate(Bundle savedInstanceState) {
mServiceMessenger = (Messenger)extras.getParcelable("myHandler");
}


private void sendDatatoService(String data){
Intent serviceIntent= new 
Intent(BaseActivity.this,Service.class);
Message msg = Message.obtain();
msg.obj =data;
msg.arg1=Service.DO_SOMETHING;
mServiceMessenger.send(msg);
}

I have a longer test to try. This takes an average of 160 ns to read each line as add it to a List (Which is likely to be what you intended as dropping the newlines is not very useful.

public static void main(String... args) throws IOException {
    final int runs = 5 * 1000 * 1000;

    final ServerSocket ss = new ServerSocket(0);
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                Socket serverConn = ss.accept();
                String line = "Hello World!\n";
                BufferedWriter br = new BufferedWriter(new OutputStreamWriter(serverConn.getOutputStream()));
                for (int count = 0; count < runs; count++)
                    br.write(line);
                serverConn.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }).start();

    Socket conn = new Socket("localhost", ss.getLocalPort());

    long start = System.nanoTime();
    BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
    String line;

    List<String> responseData = new ArrayList<String>();
    while ((line = in.readLine()) != null) {
        responseData.add(line);
    }
    long time = System.nanoTime() - start;
    System.out.println("Average time to read a line was " + time / runs + " ns.");
    conn.close();
    ss.close();
}

prints

Average time to read a line was 158 ns.

If you want to build a StringBuilder, keeping newlines I would suggets the following approach.

Reader r = new InputStreamReader(conn.getInputStream());
String line;

StringBuilder sb = new StringBuilder();
char[] chars = new char[4*1024];
int len;
while((len = r.read(chars))>=0) {
    sb.append(chars, 0, len);
}

Still prints

Average time to read a line was 159 ns.

In both cases, the speed is limited by the sender not the receiver. By optimising the sender, I got this timing down to 105 ns per line.

For me the macro didn't update the x-axis for all series, but only the first one. The solution I found was to update the x-axis for all series and then it refrehsed (also I had code to change the format of the x-axis, but I don't think that that was the problem).

Tim Lentine's answer seems to be true even in the full release. There is just one other thing I would like to mention.

If you complete your import without going into "Advanced..." and saving the spec, but you do save the import for reuse at the end of the wizard (new feature AFAIK), you will not be able to go back and edit that spec. It is built into the "Saved Import". This may be what Knox was referring to.

You can, however, do a partial work around:

1. Import a new file (or the same one all over again) but,
2. This time choose to append, instead of making a new
3. Click OK.
4. Go into "advanced" All your column heading and data-types will be there.
5. Now you can make the changes you need and save the spec inside that dialog. Then cancel out of that import (that is not what you wanted anyway, right?)
6. You can then use that spec for any further imports. It's not a full solution, but saves some of the work.

In addition to the other answers here showing you how to git checkout <the-hash-you-want> it's worth knowing you can switch back to where you were using:

git checkout @{-1}

This is often more convenient than:

git checkout what-was-that-original-branch-called-again-question-mark

As you might anticipate, git checkout @{-2} will take you back to the branch you were at two git checkouts ago, and similarly for other numbers. If you can remember where you were for bigger numbers, you should get some kind of medal for that.

Sadly for productivity, git checkout @{1} does not take you to the branch you will be on in future, which is a shame.

A better way: custom template filter: https://docs.djangoproject.com/en/dev/howto/custom-template-tags/

such as get my_list[x] in templates:

in template

{% load index %}
{{ my_list|index:x }}

templatetags/index.py

from django import template
register = template.Library()

@register.filter
def index(indexable, i):
    return indexable[i]

if my_list = [['a','b','c'], ['d','e','f']], you can use {{ my_list|index:x|index:y }} in template to get my_list[x][y]

It works fine with "for"

{{ my_list|index:forloop.counter0 }}

Tested and works well ^_^

With iOS 7+, static Launch Images are now deprecated.

You should create a custom view that composes slices of images, which sizes to all screens like a normal UIViewController view.

Running git stash pop or git stash apply is essentially a merge. You shouldn't have needed to commit your current changes unless the files changed in the stash are also changed in the working copy, in which case you would've seen this error message:

error: Your local changes to the following files would be overwritten by merge:
       file.txt
Please, commit your changes or stash them before you can merge.
Aborting

In that case, you can't apply the stash to your current changes in one step. You can commit the changes, apply the stash, commit again, and squash those two commits using git rebase if you really don't want two commits, but that may be more trouble that it's worth.

stat() works on Linux., UNIX and Windows as well:

#include <sys/stat.h>

struct stat info;

if( stat( pathname, &info ) != 0 )
    printf( "cannot access %s\n", pathname );
else if( info.st_mode & S_IFDIR )  // S_ISDIR() doesn't exist on my windows 
    printf( "%s is a directory\n", pathname );
else
    printf( "%s is no directory\n", pathname );

From lambda answer, I have made something closer to the requirements.

boolean imageCreated = false;

Bitmap bmp = null;
Marker currentLocationMarker;
private void doSomeCustomizationForMarker(LatLng currentLocation) {
    if (!imageCreated) {
        imageCreated = true;
        Bitmap.Config conf = Bitmap.Config.ARGB_8888;
        bmp = Bitmap.createBitmap(400, 400, conf);
        Canvas canvas1 = new Canvas(bmp);

        Paint color = new Paint();
        color.setTextSize(30);
        color.setColor(Color.WHITE);

        BitmapFactory.Options opt = new BitmapFactory.Options();
        opt.inMutable = true;

        Bitmap imageBitmap=BitmapFactory.decodeResource(getResources(),
                R.drawable.messi,opt);
        Bitmap resized = Bitmap.createScaledBitmap(imageBitmap, 320, 320, true);
        canvas1.drawBitmap(resized, 40, 40, color);

        canvas1.drawText("Le Messi", 30, 40, color);

        currentLocationMarker = mMap.addMarker(new MarkerOptions().position(currentLocation)
                .icon(BitmapDescriptorFactory.fromBitmap(bmp))
                // Specifies the anchor to be at a particular point in the marker image.
                .anchor(0.5f, 1));
    } else {
        currentLocationMarker.setPosition(currentLocation);
    }

}

The first version is a null object while the second is an Array object with zero elements.

Null may mean here for example that no location is available for that user, no location has been requested or that some restrictions apply. Hard to tell with no reference to the API.

Let me first highlight three different ways for similar purpose.

length -- arrays (int[], double[], String[]) -- to know the length of the arrays

length() -- String related Object (String, StringBuilder, etc) -- to know the length of the String

size() -- Collection Object (ArrayList, Set, etc) -- to know the size of the Collection

Now forget about length() consider just length and size().

length is not a method, so it completely makes sense that it will not work on objects. It only works on arrays.
size() its name describes it better and as it is a method, it will be used in the case of those objects who work with collection (collection frameworks) as I said up there.

Now come to length():
String is not a primitive array (so we can't use .length) and also not a Collection (so we cant use .size()) that's why we also need a different one which is length() (keep the differences and serve the purpose).

As answer to Why?
I find it useful, easy to remember and use and friendly.

This is the best solution provided by Google Developers. Simply call this method in onResume of onCreate after initializing GoogleApiClient.

                            status.startResolutionForResult(
                                    MainActivity.this,

                        // to fix the settings so we won't show the dialog.

You need to define a single locale that you will use for the data stored in the database, the invariant culture is there for exactly this purpose.

When you display convert to the native type and then format for the user's culture.

E.g. to display:

string fromDb = "123.56";
string display = double.Parse(fromDb, CultureInfo.InvariantCulture).ToString(userCulture);

to store:

string fromUser = "132,56";
double value;
// Probably want to use a more specific NumberStyles selection here.
if (!double.TryParse(fromUser, NumberStyles.Any, userCulture, out value)) {
  // Error...
}
string forDB = value.ToString(CultureInfo.InvariantCulture);

PS. It, almost, goes without saying that using a column with a datatype that matches the data would be even better (but sometimes legacy applies).

We managed to solve the error under Windows Server 2012 by:

1. Removing from "Remove Roles and Features Wizard" .NET Framework 4.5 Features/ASP.NET 4.5 and all its dependent features
2. Re-installing the removed features.

It seems the order of installation is the cause.

Also, make sure you have HTTP Activation installed under WCF Services.

Here's a (very inefficient) way to get all (i.e. even overlapping) matches:

>>> string = "test test test test"
>>> [i for i in range(len(string)) if string.startswith('test', i)]
[0, 5, 10, 15]

When you try doing

ssh -i <.pem path> root@ec2-public-dns

You get a message advising you to use the ec2-user.

Please login as the user "ec2-user" rather than the user "root".

So use

ssh -i <.pem path> ec2-user@ec2-public-dns

The mysql_install_db script also needs the datadir parameter:

mysql_install_db --user=root --datadir=$db_datapath

On Maria DB you use the install script mysql_install_db to install and initialize. In my case I use an environment variable for the data path. Not only does mysqld need to know where the data is (specified via commandline), but so does the install script.

The easiest way: Just double click on this button and choose "NoTitleBar" ;)

The error occured since JAVA is not installed on machine. Spark is developed in scala which usually runs on JAVA.

Try to install JAVA and execute the pyspark statements. It will works

This is the working code for your question.

There is an alternative solution that might be adaptable to the RichTextBox oultined in this blog post - it used a trigger to swap out the control template when the use hovers over the control - should help with performance

Click on the Add Library button. It brings your screen to point to the Java location.

Select "Directory", button right besides JRE home and point to the installed folder location.

Even though you want to just 1.5 compiler project, you can achieve it by changing compiler settings in Eclipse instead of removing 1.6 JRE and add 1.5 JRE.

GOTO -->JAVA--Compiler---> and change compiler level to `1.5` instead of `1.6`

As davidfmatheson suggested,

Just be careful, especially if you're setting this up for a team of people to work on. If anyone uses anything that is new or changed in 1.6, it will compile, but not run in an environment with JRE 1.5.

First step, you have to set your autofocus attribute on form input.

<input name="full_name" autofocus/>

And then you have to add declaration to set autofocus of your input after your modal is shown.
Try this code :

$(document).on('ready', function(){
    // Set modal form input to autofocus when autofocus attribute is set
    $('.modal').on('shown.bs.modal', function () {
        $(this).find($.attr('autofocus')).focus();
    });
});

Here is how I would do it, (however I would use an external style sheet for this project and all others. just makes things easier to work with. Also this example is with html5.

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style>
  .container {
      display:inline-block;
  }
</style>
</head>
<body>

  <div class="container">
    <figure>
    <img src="http://placehold.it/350x150" height="200" width="200">
    <figcaption>This is image 1</figcaption>
    </figure>

    <figure>
    <img class="middle-img" src="http://placehold.it/350x150"/ height="200" width="200">
    <figcaption>This is image 2</figcaption>
    </figure>

    <figure>
    <img src="http://placehold.it/350x150" height="200" width="200">

Sub SelectAllCellsInSheet(SheetName As String)
    lastCol = Sheets(SheetName).Range("a1").End(xlToRight).Column
    Lastrow = Sheets(SheetName).Cells(1, 1).End(xlDown).Row
    Sheets(SheetName).Range("A2", Sheets(SheetName).Cells(Lastrow, lastCol)).Select
End Sub

To use with ActiveSheet:

Call SelectAllCellsInSheet(ActiveSheet.Name)

Since API 16 you can supply an activity options bundle when calling Context.startActivity(Intent, Bundle) or related methods. It is created via the ActivityOptions builder:

Intent myIntent = new Intent(context, MyActivity.class);
ActivityOptions options = 
   ActivityOptions.makeCustomAnimation(context, R.anim.fade_in, R.anim.fade_out);
context.startActivity(myIntent, options.toBundle());

Don't forget to check out the other methods of the ActivityOptions builder and the ActivityOptionsCompat if you are using the Support Library.

API 5+:

For apps targeting API level 5+ there is the Activities overridePendingTransition method. It takes two resource IDs for the incoming and outgoing animations. An id of 0 will disable the animations. Call this immediately after the startActivity call.

i.e.:

startActivity(new Intent(this, MyActivity.class));
overridePendingTransition(R.anim.fade_in, R.anim.fade_out);

API 3+:

You can prevent the default animation (Slide in from the right) with the Intent.FLAG_ACTIVITY_NO_ANIMATION flag in your intent.

i.e.:

Intent myIntent = new Intent(context, MyActivity.class);
myIntent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
context.startActivity(myIntent);

then in your Activity you simply have to specify your own animation.

This also works for the 1.5 API (Level 3).

You can use a function like strtol() which will convert a character array to a long.

It has a parameter which is a way to detect the first character that didn't convert properly. If this is anything other than the end of the string, then you have a problem.

See the following program for an example:

#include <stdio.h>
#include <stdlib.h>

int main( int argc, char *argv[]) {
    int i;
    long val;
    char *next;

    // Process each argument given.

    for (i = 1; i < argc; i++) {
        // Get value with failure detection.

        val = strtol (argv[i], &next, 10);

        // Check for empty string and characters left after conversion.

        if ((next == argv[i]) || (*next != '\0')) {
            printf ("'%s' is not valid\n", argv[i]);
        } else {
            printf ("'%s' gives %ld\n", argv[i], val);
        }
    }

    return 0;
}

Running this, you can see it in operation:

pax> testprog hello "" 42 12.2 77x

'hello' is not valid
'' is not valid
'42' gives 42
'12.2' is not valid
'77x' is not valid

you should use magic methods __Set and __get. Simple example:

class Foo
{
    //This array stores your properties
private $content = array();

public function __set($key, $value)
{
            //Perform data validation here before inserting data
    $this->content[$key] = $value;
    return $this;
}

public function __get($value)
{       //You might want to check that the data exists here
    return $this->$content[$value];
}

}

Of course, don't use this example as this : no security at all :)

EDIT : seen your comments, here could be an alternative based on reflection and a decorator :

 class Foo
 {
private $content = array();
private $stdInstance;

public function __construct($stdInstance)
{
    $this->stdInstance = $stdInstance;
}

public function __set($key, $value)
{
    //Reflection for the stdClass object
    $ref = new ReflectionClass($this->stdInstance);
    //Fetch the props of the object

    $props = $ref->getProperties();

    if (in_array($key, $props)) {
        $this->stdInstance->$key = $value;
    } else {
        $this->content[$key] = $value;
    }
    return $this;
}

public function __get($value)
{
    //Search first your array as it is faster than using reflection
    if (array_key_exists($value, $this->content))
    {
        return $this->content[$value];
    } else {
        $ref = new ReflectionClass($this->stdInstance);

        //Fetch the props of the object
        $props = $ref->getProperties();

        if (in_array($value, $props)) {

        return $this->stdInstance->$value;
    } else {
        throw new \Exception('No prop in here...');
    }
}
 }
}

PS : I didn't test my code, just the general idea...

I was having this problem with Android Studio when I'm behind a proxy. I was using Crashlytics that tries to upload the mapping file during a build.

I added the missing proxy certificate to the truststore located at /Users/[username]/Documents/Android Studio.app/Contents/jre/jdk/Contents/Home/jre/lib/security/cacerts

with the following command: keytool -import -trustcacerts -keystore cacerts -storepass [password] -noprompt -alias [alias] -file [my_certificate_location]

for example with the default truststore password keytool -import -trustcacerts -keystore cacerts -storepass changeit -noprompt -alias myproxycert -file /Users/myname/Downloads/MyProxy.crt

For me, ensuring that I had:

#include <iostream>  
#include<string>  
using namespace std;

in my file made something like to_string(12345) work.

// Use a BufferedReader to read characters from the console.
import java.io.*;
class BRRead {
public static void main(String args[]) throws IOException
{
char c;
BufferedReader br = new
BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter characters, 'q' to quit.");
// read characters
do {
c = (char) br.read();
System.out.println(c);
} while(c != 'q');
}
}

select t.* from table t
    join (
        select C2, C3, C4
        from table
        group by C2, C3, C4
        having count(*) > 1
    ) t2
    using (C2, C3, C4);

I had the same issue but when i deleted the cached items from Temp folder the build failed.

In order to make the build work again I had to close the project and reopen it.

The Problem is with your code formatting,

inorder to use strtotime() You should replace '06/Oct/2011:19:00:02' with 06/10/2011 19:00:02 and date('d/M/Y:H:i:s', $date); with date('d/M/Y H:i:s', $date);. Note the spaces in between.

So the final code looks like this

$s = '06/10/2011 19:00:02';
$date = strtotime($s);
echo date('d/M/Y H:i:s', $date);

Here's what's actually happening localhost means that you want to open htdocs. First it will search for any file named index.php or index.html. If one of those exist it will open the file. If neither of those exist then it will open all folder/file inside htdocs directory which is what you want.

So, the simplest solution is to rename index.php or index.html to index2.php etc.

A Json Web Token made up of three parts. The header, the payload and the signature Now the header is just some metadata about the token itself and the payload is the data that we can encode into the token, any data really that we want. So the more data we want to encode here the bigger the JWT. Anyway, these two parts are just plain text that will get encoded, but not encrypted.

So anyone will be able to decode them and to read them, we cannot store any sensitive data in here. But that's not a problem at all because in the third part, so in the signature, is where things really get interesting. The signature is created using the header, the payload, and the secret that is saved on the server.

And this whole process is then called signing the Json Web Token. The signing algorithm takes the header, the payload, and the secret to create a unique signature. So only this data plus the secret can create this signature, all right? Then together with the header and the payload, these signature forms the JWT, which then gets sent to the client.

Once the server receives a JWT to grant access to a protected route, it needs to verify it in order to determine if the user really is who he claims to be. In other words, it will verify if no one changed the header and the payload data of the token. So again, this verification step will check if no third party actually altered either the header or the payload of the Json Web Token.

So, how does this verification actually work? Well, it is actually quite straightforward. Once the JWT is received, the verification will take its header and payload, and together with the secret that is still saved on the server, basically create a test signature.

But the original signature that was generated when the JWT was first created is still in the token, right? And that's the key to this verification. Because now all we have to do is to compare the test signature with the original signature. And if the test signature is the same as the original signature, then it means that the payload and the header have not been modified.

Because if they had been modified, then the test signature would have to be different. Therefore in this case where there has been no alteration of the data, we can then authenticate the user. And of course, if the two signatures are actually different, well, then it means that someone tampered with the data. Usually by trying to change the payload. But that third party manipulating the payload does of course not have access to the secret, so they cannot sign the JWT. So the original signature will never correspond to the manipulated data. And therefore, the verification will always fail in this case. And that's the key to making this whole system work. It's the magic that makes JWT so simple, but also extremely powerful.

Now let's do some practices with nodejs:

Configuration file is perfect for storing JWT SECRET data. Using the standard HSA 256 encryption for the signature, the secret should at least be 32 characters long, but the longer the better.

config.env:

JWT_SECRET = my-32-character-ultra-secure-and-ultra-long-secret
//after 90days JWT will no longer be valid, even the signuter is correct and everything is matched.
JWT_EXPIRES_IN=90

now install JWT using command

npm i jsonwebtoken

Example after user signup passing him JWT token so he can stay logged in and get access of resources.

exports.signup = catchAsync(async (req, res, next) => {
  const newUser = await User.create({
    name: req.body.name,
    email: req.body.email,
    password: req.body.password,
    passwordConfirm: req.body.passwordConfirm,
  });
  const token = jwt.sign({ id: newUser._id }, process.env.JWT_SECRET, {
    expiresIn: process.env.JWT_EXPIRES_IN,
  });

  res.status(201).json({
    status: 'success',
    token,
    data: {
      newUser,
    },
  });
});

output:

In my opinion, do not take help from a third-party to generate your super-secret key, because you can't say it's secret anymore. Just use your keyboard.

It is the same as in eclipse:

• Select text for upper case and Ctrl + Shift + X
• Select text for lower case and Ctrl + Shift + Y

You can create bitmap with captured image as below:

Bitmap bitmap = Bitmap.createScaledBitmap(capturedImage, width, height, true);

Here you can specify width and height of the bitmap that you want to set to your ImageView. The height and width you can set according to the screen dpi of the device also, by reading the screen dpi of different devices programmatically.

If the server sends some status code different than 200, the error callback is executed:

$.ajax({
    url: '/foo',
    success: function(result) {
        alert('yeap');
    },
    error: function(XMLHttpRequest, textStatus, errorThrown) {
        alert('oops, something bad happened');
    }
});

and to register a global error handler you could use the $.ajaxSetup() method:

$.ajaxSetup({
    error: function(XMLHttpRequest, textStatus, errorThrown) {
        alert('oops, something bad happened');
    }
});

Another way is to use JSON. So you could write a custom action filter on the server which catches exception and transforms them into JSON response:

public class MyErrorHandlerAttribute : FilterAttribute, IExceptionFilter
{
    public void OnException(ExceptionContext filterContext)
    {
        filterContext.ExceptionHandled = true;
        filterContext.Result = new JsonResult
        {
            Data = new { success = false, error = filterContext.Exception.ToString() },
            JsonRequestBehavior = JsonRequestBehavior.AllowGet
        };
    }
}

and then decorate your controller action with this attribute:

[MyErrorHandler]
public ActionResult Foo(string id)
{
    if (string.IsNullOrEmpty(id))
    {
        throw new Exception("oh no");
    }
    return Json(new { success = true });
}

and finally invoke it:

$.getJSON('/home/foo', { id: null }, function (result) {
    if (!result.success) {
        alert(result.error);
    } else {
        // handle the success
    }
});

You can easily change the match-type to 1 when you are looking for the greatest value or to -1 when looking for the smallest value.

We can do like below:

Create a new object of notification builder and call setSmallIcon() using notification builder object like in below code.

Create a method in which we will check on which OS version we are installing our app . If it is below Lolipop i.e API 21 then it will take the normal app icon with background color else it will take the transparent app icon without any background. So the devices using os version >= 21 will set the background color of icon using method setColor() of Notification builder class.

Sample Code:

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);

notificationBuilder.setSmallIcon(getNotificationIcon(notificationBuilder));

private int getNotificationIcon(NotificationCompat.Builder notificationBuilder) {

   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
             int color = 0x008000;
             notificationBuilder.setColor(color);
             return R.drawable.app_icon_lolipop_above;

    } 
    return R.drawable.app_icon_lolipop_below;
}

try:

var myjson = '{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}';
var newJ= $.parseJSON(myjson);
    alert(newJ.TeamList[0].teamname);

You can use the provider-specific ConnectionStringBuilder class (within the appropriate namespace), or System.Data.Common.DbConnectionStringBuilder to abstract the connection string object if you need to. You'd need to know the provider-specific keywords used to designate the information you're looking for, but for a SQL Server example you could do either of these two things:

System.Data.SqlClient.SqlConnectionStringBuilder builder = new System.Data.SqlClient.SqlConnectionStringBuilder(connectionString);

string server = builder.DataSource;
string database = builder.InitialCatalog;

or

System.Data.Common.DbConnectionStringBuilder builder = new System.Data.Common.DbConnectionStringBuilder();

builder.ConnectionString = connectionString;

string server = builder["Data Source"] as string;
string database = builder["Initial Catalog"] as string;

you should use position: relative; for one iframe and position:absolute; for the second;

Example: for first iframe use:

<div id="contentframe" style="position:relative; top: 100px; left: 50px;">

for second iframe use:

<div id="contentframe" style="position:absolute; top: 0px; left: 690px;">

In this mode you can find all element which has class active and remove it

try this

$(document).ready(function() {
        $(this.attr('id')).click(function () {
           $(document).find('.active').removeClass('active');
           var DivId = $(this).attr('id');
           alert(DivId);
           $(this).addClass('active');
        });
  });

The IP addresses have changed again.

github publishes the list of used IP addresses here so you can check the IP address in your message against github's list:

https://help.github.com/articles/about-github-s-ip-addresses/

Or more precisely:

https://api.github.com/meta

It looks like this (as I write this answer!):

verifiable_password_authentication  true
github_services_sha "4159703d573ee6f602e304ed25b5862463a2c73d"

1   "54.166.52.62"
2   "23.20.92.3"

If you are unsure whether your IP address is contained in the above list use an CIDR calculator like http://www.subnet-calculator.com/cidr.php to show the valid IP range.

E. g. for 140.82.112.0/20 the IP range is 140.82.112.0 - 140.82.127.255

This is what I expected to see when I came to this question:

Two nitpicks. (1) Best not to use string literals for column alias - that is deprecated. (2) Just use style 120 to get the same value.

Installing from vanilla https github URLs now works:

npm install https://github.com/fergiemcdowall/search-index.git

EDIT 1: You can't do this for all modules because you are reading from a source control system, which may well contain invalid/uncompiled/buggy code. So to be clear (although it should go without saying): given that the code in the repo is in an npm-usable state, you can now quite happily install directly from github

EDIT 2: (21-10-2019) We are now living through "peak Typescript/React/Babel", and therefore JavaScript compilation has become quite common. If you need to take compilation into account look into prepare. That said, NPM modules do not need to be compiled, and it is wise to assume that compilation is not the default, especially for older node modules (and possibly also for very new, bleeding-edge "ESNext"-y ones).

If you are in the fragment itself, you need to call this. Your fragment needs to be the fragment that is being called. Enter code:

getFragmentManager().beginTransaction().remove(yourFragment).commitAllowingStateLoss();

or if you are using supportLib, then you need to call:

getSupportFragmentManager().beginTransaction().remove(yourFragment).commitAllowingStateLoss();

I had similar problem with regex = "?". It happens for all special characters that have some meaning in a regex. So you need to have "\\" as a prefix to your regex.

String [] separado = line.split("\\*");

You can do something similar:

var tuple = Object.freeze({ name:'Bob', age:14 })

and then refer to name and age as attributes

tuple.name 
tuple.age 

The credit/debit card number is referred to as a PAN, or Primary Account Number. The first six digits of the PAN are taken from the IIN, or Issuer Identification Number, belonging to the issuing bank (IINs were previously known as BIN — Bank Identification Numbers — so you may see references to that terminology in some documents). These six digits are subject to an international standard, ISO/IEC 7812, and can be used to determine the type of card from the number.

Unfortunately the actual ISO/IEC 7812 database is not publicly available, however, there are unofficial lists, both commercial and free, including on Wikipedia.

Anyway, to detect the type from the number, you can use a regular expression like the ones below: Credit for original expressions

Visa: ^4[0-9]{6,}$ Visa card numbers start with a 4.

MasterCard: ^5[1-5][0-9]{5,}|222[1-9][0-9]{3,}|22[3-9][0-9]{4,}|2[3-6][0-9]{5,}|27[01][0-9]{4,}|2720[0-9]{3,}$ Before 2016, MasterCard numbers start with the numbers 51 through 55, but this will only detect MasterCard credit cards; there are other cards issued using the MasterCard system that do not fall into this IIN range. In 2016, they will add numbers in the range (222100-272099).

American Express: ^3[47][0-9]{5,}$ American Express card numbers start with 34 or 37.

Diners Club: ^3(?:0[0-5]|[68][0-9])[0-9]{4,}$ Diners Club card numbers begin with 300 through 305, 36 or 38. There are Diners Club cards that begin with 5 and have 16 digits. These are a joint venture between Diners Club and MasterCard and should be processed like a MasterCard.

Discover: ^6(?:011|5[0-9]{2})[0-9]{3,}$ Discover card numbers begin with 6011 or 65.

JCB: ^(?:2131|1800|35[0-9]{3})[0-9]{3,}$ JCB cards begin with 2131, 1800 or 35.

Unfortunately, there are a number of card types processed with the MasterCard system that do not live in MasterCard’s IIN range (numbers starting 51...55); the most important case is that of Maestro cards, many of which have been issued from other banks’ IIN ranges and so are located all over the number space. As a result, it may be best to assume that any card that is not of some other type you accept must be a MasterCard.

Important: card numbers do vary in length; for instance, Visa has in the past issued cards with 13 digit PANs and cards with 16 digit PANs. Visa’s documentation currently indicates that it may issue or may have issued numbers with between 12 and 19 digits. Therefore, you should not check the length of the card number, other than to verify that it has at least 7 digits (for a complete IIN plus one check digit, which should match the value predicted by the Luhn algorithm).

One further hint: before processing a cardholder PAN, strip any whitespace and punctuation characters from the input. Why? Because it’s typically much easier to enter the digits in groups, similar to how they’re displayed on the front of an actual credit card, i.e.

4444 4444 4444 4444

is much easier to enter correctly than

4444444444444444

There’s really no benefit in chastising the user because they’ve entered characters you don't expect here.

This also implies making sure that your entry fields have room for at least 24 characters, otherwise users who enter spaces will run out of room. I’d recommend that you make the field wide enough to display 32 characters and allow up to 64; that gives plenty of headroom for expansion.

Here's an image that gives a little more insight:

UPDATE (2014): The checksum method no longer appears to be a valid way of verifying a card's authenticity as noted in the comments on this answer.

UPDATE (2016): Mastercard is to implement new BIN ranges starting Ach Payment.

Just need to add: new SimpleDateFormat("bla bla bla", Locale.US)

public static void main(String[] args) throws ParseException {
    java.util.Date fecha = new java.util.Date("Mon Dec 15 00:00:00 CST 2014");
    DateFormat formatter = new SimpleDateFormat("EEE MMM dd HH:mm:ss Z yyyy", Locale.US);
    Date date;
    date = (Date)formatter.parse(fecha.toString());
    System.out.println(date);        

    Calendar cal = Calendar.getInstance();
    cal.setTime(date);
    String formatedDate = cal.get(Calendar.DATE) + "/" + 
            (cal.get(Calendar.MONTH) + 1) + 
            "/" +         cal.get(Calendar.YEAR);
    System.out.println("formatedDate : " + formatedDate);
}

Each commit has a unique hash. Other than that there are no revision numbers in git. You'll have to tag commits yourself if you want more user-friendliness.

mgrandi provided a very good resource and answer. I followed similar guidelines and by removing 'leftover' components managed to solve the problem.

As a reference, take a look at Windows SDK for Windows 7 and .NET Framework 4 Release Notes.

This downloads the release notes of the SDK (you should also have it on your computer after trying to install the SDK), and in the section 'Installing and Uninstalling the Windows SDK' you can see that Microsoft recommend cleaning some mess after them.

I noticed that //noinspection can be auto-generated in IntelliJ

• make sure you have not already a plan @SuppressWarninigs before the statement
• Now you can auto-generate the specific //noinspection by hitting Alt+Enter when you have the warning selected and then use the right arrow key to see the Suppress for ... option

Ended up here when I wanted to suppress a "switch has too few case labels" warning from IntelliJ. I did not find a complete List for IntelliJ's @SuppressWarning support but //noinspection did the trick for me.

With Python>3.5, using glob, . pointing to your current folder and looking for .txt files:

 python -c "import glob;[print(x) for x in glob.glob('./**/*txt', recursive=True)]"

For older versions of Python, you can install glob2

You need to use reflection to get the method to start with, then "construct" it by supplying type arguments with MakeGenericMethod:

MethodInfo method = typeof(Sample).GetMethod(nameof(Sample.GenericMethod));
MethodInfo generic = method.MakeGenericMethod(myType);
generic.Invoke(this, null);

For a static method, pass null as the first argument to Invoke. That's nothing to do with generic methods - it's just normal reflection.

As noted, a lot of this is simpler as of C# 4 using dynamic - if you can use type inference, of course. It doesn't help in cases where type inference isn't available, such as the exact example in the question.

This should solve your problem:

select replace(to_char(a, '90D90'),'.00','')
from
(
select 50 a from dual
union
select 50.57 from dual
union
select 5.57 from dual
union
select 0.35 from dual
union
select 0.4 from dual
);

Best way to is install virtualenv and not require the --user confusion. You will get more flexibility and not worry about clobbering the different python versions and projects everytime you pip install a package.

Why would a “java.net.ConnectException: Connection timed out” exception occur when URL is up?

Because the URLConnection (HttpURLConnection/HttpsURLConnection) is erratic. You can read about this here and here. Our solution were two things:

a) set the ContentLength via setFixedLengthStreamingMode

b) catch any TimeoutException and retry if it failed.

Please be aware that the accepted answer is a bit incomplete. Yes, at the most basic level Collation handles sorting. BUT, the comparison rules defined by the chosen Collation are used in many places outside of user queries against user data.

If "What does COLLATE SQL_Latin1_General_CP1_CI_AS do?" means "What does the COLLATE clause of CREATE DATABASE do?", then:

The COLLATE {collation_name} clause of the CREATE DATABASE statement specifies the default Collation of the Database, and not the Server; Database-level and Server-level default Collations control different things.

Server (i.e. Instance)-level controls:

• Database-level Collation for system Databases: master, model, msdb, and tempdb.
• Due to controlling the DB-level Collation of tempdb, it is then the default Collation for string columns in temporary tables (global and local), but not table variables.
• Due to controlling the DB-level Collation of master, it is then the Collation used for Server-level data, such as Database names (i.e. name column in sys.databases), Login names, etc.
• Handling of parameter / variable names
• Handling of cursor names
• Handling of GOTO labels
• Default Collation used for newly created Databases when the COLLATE clause is missing

Database-level controls:

• Default Collation used for newly created string columns (CHAR, VARCHAR, NCHAR, NVARCHAR, TEXT, and NTEXT -- but don't use TEXT or NTEXT) when the COLLATE clause is missing from the column definition. This goes for both CREATE TABLE and ALTER TABLE ... ADD statements.
• Default Collation used for string literals (i.e. 'some text') and string variables (i.e. @StringVariable). This Collation is only ever used when comparing strings and variables to other strings and variables. When comparing strings / variables to columns, then the Collation of the column will be used.
• The Collation used for Database-level meta-data, such as object names (i.e. sys.objects), column names (i.e. sys.columns), index names (i.e. sys.indexes), etc.
• The Collation used for Database-level objects: tables, columns, indexes, etc.

Also:

• ASCII is an encoding which is 8-bit (for common usage; technically "ASCII" is 7-bit with character values 0 - 127, and "ASCII Extended" is 8-bit with character values 0 - 255). This group is the same across cultures.
• The Code Page is the "extended" part of Extended ASCII, and controls which characters are used for values 128 - 255. This group varies between each culture.
• Latin1 does not mean "ASCII" since standard ASCII only covers values 0 - 127, and all code pages (that can be represented in SQL Server, and even NVARCHAR) map those same 128 values to the same characters.

If "What does COLLATE SQL_Latin1_General_CP1_CI_AS do?" means "What does this particular collation do?", then:

• Because the name start with SQL_, this is a SQL Server collation, not a Windows collation. These are definitely obsolete, even if not officially deprecated, and are mainly for pre-SQL Server 2000 compatibility. Although, quite unfortunately SQL_Latin1_General_CP1_CI_AS is very common due to it being the default when installing on an OS using US English as its language. These collations should be avoided if at all possible.

  Windows collations (those with names not starting with SQL_) are newer, more functional, have consistent sorting between VARCHAR and NVARCHAR for the same values, and are being updated with additional / corrected sort weights and uppercase/lowercase mappings. These collations also don't have the potential performance problem that the SQL Server collations have: Impact on Indexes When Mixing VARCHAR and NVARCHAR Types.

• Latin1_General is the culture / locale.
  • For NCHAR, NVARCHAR, and NTEXT data this determines the linguistic rules used for sorting and comparison.
  • For CHAR, VARCHAR, and TEXT data (columns, literals, and variables) this determines the:
    • linguistic rules used for sorting and comparison.
    • code page used to encode the characters. For example, Latin1_General collations use code page 1252, Hebrew collations use code page 1255, and so on.

• CP{code_page} or {version}

  • For SQL Server collations: CP{code_page}, is the 8-bit code page that determines what characters map to values 128 - 255. While there are four code pages for Double-Byte Character Sets (DBCS) that can use 2-byte combinations to create more than 256 characters, these are not available for the SQL Server collations.

  • For Windows collations: {version}, while not present in all collation names, refers to the SQL Server version in which the collation was introduced (for the most part). Windows collations with no version number in the name are version 80 (meaning SQL Server 2000 as that is version 8.0). Not all versions of SQL Server come with new collations, so there are gaps in the version numbers. There are some that are 90 (for SQL Server 2005, which is version 9.0), most are 100 (for SQL Server 2008, version 10.0), and a small set has 140 (for SQL Server 2017, version 14.0).

    I said "for the most part" because the collations ending in _SC were introduced in SQL Server 2012 (version 11.0), but the underlying data wasn't new, they merely added support for supplementary characters for the built-in functions. So, those endings exist for version 90 and 100 collations, but only starting in SQL Server 2012.

• Next you have the sensitivities, that can be in any combination of the following, but always specified in this order:
  • CS = case-sensitive or CI = case-insensitive
  • AS = accent-sensitive or AI = accent-insensitive
  • KS = Kana type-sensitive or missing = Kana type-insensitive
  • WS = width-sensitive or missing = width insensitive
  • VSS = variation selector sensitive (only available in the version 140 collations) or missing = variation selector insensitive

• Optional last piece:

  • _SC at the end means "Supplementary Character support". The "support" only affects how the built-in functions interpret surrogate pairs (which are how supplementary characters are encoded in UTF-16). Without _SC at the end (or _140_ in the middle), built-in functions don't see a single supplementary character, but instead see two meaningless code points that make up the surrogate pair. This ending can be added to any non-binary, version 90 or 100 collation.
  • _BIN or _BIN2 at the end means "binary" sorting and comparison. Data is still stored the same, but there are no linguistic rules. This ending is never combined with any of the 5 sensitivities or _SC. _BIN is the older style, and _BIN2 is the newer, more accurate style. If using SQL Server 2005 or newer, use _BIN2. For details on the differences between _BIN and _BIN2, please see: Differences Between the Various Binary Collations (Cultures, Versions, and BIN vs BIN2).

  • _UTF8 is a new option as of SQL Server 2019. It's an 8-bit encoding that allows for Unicode data to be stored in VARCHAR and CHAR datatypes (but not the deprecated TEXT datatype). This option can only be used on collations that support supplementary characters (i.e. version 90 or 100 collations with _SC in their name, and version 140 collations). There is also a single binary _UTF8 collation (_BIN2, not _BIN).

    PLEASE NOTE: UTF-8 was designed / created for compatibility with environments / code that are set up for 8-bit encodings yet want to support Unicode. Even though there are a few scenarios where UTF-8 can provide up to 50% space savings as compared to NVARCHAR, that is a side-effect and has a cost of a slight hit to performance in many / most operations. If you need this for compatibility, then the cost is acceptable. If you want this for space-savings, you had better test, and TEST AGAIN. Testing includes all functionality, and more than just a few rows of data. Be warned that UTF-8 collations work best when ALL columns, and the database itself, are using VARCHAR data (columns, variables, string literals) with a _UTF8 collation. This is the natural state for anyone using this for compatibility, but not for those hoping to use it for space-savings. Be careful when mixing VARCHAR data using a _UTF8 collation with either VARCHAR data using non-_UTF8 collations or NVARCHAR data, as you might experience odd behavior / data loss. For more details on the new UTF-8 collations, please see: Native UTF-8 Support in SQL Server 2019: Savior or False Prophet?
