The following complete example will read an existing server.xml file from the current directory, append a new Server and re-write the file to server.xml. It does not work without an existing .xml file, so you will need to modify the code to handle that case.

import java.util.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.dom.*;
import org.w3c.dom.*;
import javax.xml.parsers.*;

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

        DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder documentBuilder = documentBuilderFactory.newDocumentBuilder();
        Document document = documentBuilder.parse("server.xml");
        Element root = document.getDocumentElement();

        Collection<Server> servers = new ArrayList<Server>();
        servers.add(new Server());

        for (Server server : servers) {
            // server elements
            Element newServer = document.createElement("server");

            Element name = document.createElement("name");
            name.appendChild(document.createTextNode(server.getName()));
            newServer.appendChild(name);

            Element port = document.createElement("port");
            port.appendChild(document.createTextNode(Integer.toString(server.getPort())));
            newServer.appendChild(port);

            root.appendChild(newServer);
        }

        DOMSource source = new DOMSource(document);

        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        StreamResult result = new StreamResult("server.xml");
        transformer.transform(source, result);
    }

    public static class Server {
        public String getName() { return "foo"; }
        public Integer getPort() { return 12345; }
    }
}

Example server.xml file:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Servers>
  <server>
    <name>something</name>
    <port>port</port>
  </server>
</Servers>

The main change to your code is not creating a new "root" element. The above example just uses the current root node from the existing server.xml and then just appends a new Server element and re-writes the file.

based on Wesley Coetzee's answer i wrote this. Hope it can help anyone googling this issue. I had bugs with swapping the paginator size in the middle of the list that's why i submit my answer:

Paginator html and list

<mat-paginator [length]="localNewspapers.length" pageSize=20
               (page)="getPaginatorData($event)" [pageSizeOptions]="[10, 20, 30]"
               showFirstLastButtons="false">
</mat-paginator>
<mat-list>
   <app-newspaper-pagi-item *ngFor="let paper of (localNewspapers | 
                         slice: lowValue : highValue)"
                         [newspaper]="paper"> 
  </app-newspaper-pagi-item>

Component logic

import {Component, Input, OnInit} from "@angular/core";
import {PageEvent} from "@angular/material";

@Component({
  selector: 'app-uniques-newspaper-list',
  templateUrl: './newspaper-uniques-list.component.html',
})
export class NewspaperUniquesListComponent implements OnInit {
  lowValue: number = 0;
  highValue: number = 20;

  // used to build an array of papers relevant at any given time
  public getPaginatorData(event: PageEvent): PageEvent {
    this.lowValue = event.pageIndex * event.pageSize;
    this.highValue = this.lowValue + event.pageSize;
    return event;
  }

}

The d3 print below is the one you are looking for (which is the combination of dumps and loads) :)

Having:

import json

d = """{"Aa": 1, "BB": "blabla", "cc": "False"}"""

d1 = json.loads(d)              # Produces a dictionary out of the given string
d2 = json.dumps(d)              # Produces a string out of a given dict or string
d3 = json.dumps(json.loads(d))  # 'dumps' gets the dict from 'loads' this time

print "d1:  " + str(d1)
print "d2:  " + d2
print "d3:  " + d3

Prints:

d1:  {u'Aa': 1, u'cc': u'False', u'BB': u'blabla'}
d2:  "{\"Aa\": 1, \"BB\": \"blabla\", \"cc\": \"False\"}"
d3:  {"Aa": 1, "cc": "False", "BB": "blabla"}

card = random.choice(cards)
cardsLeft = cards.replace(card, '', 1)

How to remove one character from a string: Here is an example where there is a stack of cards represented as characters in a string. One of them is drawn (import random module for the random.choice() function, that picks a random character in the string). A new string, cardsLeft, is created to hold the remaining cards given by the string function replace() where the last parameter indicates that only one "card" is to be replaced by the empty string...

You have not one, but many mistakes. It should be:

int[] tall = new int[28123];

for (int j=0;j<28123;j++){
    tall[j] = j+1;
}

Your code is putting a 0 in all the positions of the array.

Morover, it'll throw an exception, because the last index of the array is 28123-1 (arrays in Java start in 0!).

If you don't want to save any changes and don't want that Save prompt while saving an Excel file using Macro then this piece of code may helpful for you

Sub Auto_Close()

     ThisWorkbook.Saved = True

End Sub

Because the Saved property is set to True, Excel responds as though the workbook has already been saved and no changes have occurred since that last save, so no Save prompt.

You can use Symbol

var say = Symbol()

function Cat(){
  this[say]() // call private methos
}

Cat.prototype[say] = function(){ alert('im a private') }

P.S. alexpods is not correct. he get protect rather than private, since inheritance is a name conflict

Actually you can use var say = String(Math.random()) instead Symbol

IN ES6:

var say = Symbol()

class Cat {

  constructor(){
    this[say]() // call private
  }

  [say](){
    alert('im private')
  }

}

If you're really bent upon converting Integer to String value, I suggest use String.valueOf(YourIntegerVariable). More details can be found at: http://www.tutorialspoint.com/java/java_string_valueof.htm

This worked for me fine:

File 1:

    <html>
    <head></head>
    <body>
        <a href="#" onclick="window.open('file:///D:/Examples/file2.html'); return false">CLICK ME</a>
    </body>
    <footer></footer>
    </html>

File 2:

    <html>
        ...
    </html>

This method works regardless of whether or not the 2 files are in the same directory, BUT both files must be local.

For obvious security reasons, if File 1 is located on a remote server you absolutely cannot open a file on some client's host computer and trying to do so will open a blank target.

Update for mid 2016:

The things are changing so fast that if it's late 2017 this answer might not be up to date anymore!

Beginners can quickly get lost in choice of build tools and workflows, but what's most up to date in 2016 is not using Bower, Grunt or Gulp at all! With help of Webpack you can do everything directly in NPM!

• Google "npm as build tool" result: https://medium.com/@dabit3/introduction-to-using-npm-as-a-build-tool-b41076f488b0#.c33e74tsa

• Webpack: https://webpack.github.io/docs/installation.html

Don't get me wrong people use other workflows and I still use GULP in my legacy project(but slowly moving out of it), but this is how it's done in the best companies and developers working in this workflow make a LOT of money!

Look at this template it's a very up-to-date setup consisting of a mixture of the best and the latest technologies: https://github.com/coryhouse/react-slingshot

• Webpack
• NPM as a build tool (no Gulp, Grunt or Bower)
• React with Redux
• ESLint
• the list is long. Go and explore!

Your questions:

When I want to add a package (and check in the dependency into git), where does it belong - into package.json or into bower.json

• Everything belongs in package.json now

• Dependencies required for build are in "devDependencies" i.e. npm install require-dir --save-dev (--save-dev updates your package.json by adding an entry to devDependencies)

• Dependencies required for your application during runtime are in "dependencies" i.e. npm install lodash --save (--save updates your package.json by adding an entry to dependencies)

If that is the case, when should I ever install packages explicitly like that without adding them to the file that manages dependencies (apart from installing command line tools globally)?

Always. Just because of comfort. When you add a flag (--save-dev or --save) the file that manages deps (package.json) gets updated automatically. Don't waste time by editing dependencies in it manually. Shortcut for npm install --save-dev package-name is npm i -D package-name and shortcut for npm install --save package-name is npm i -S package-name

def capitalizeWords(s):
  return re.sub(r'\w+', lambda m:m.group(0).capitalize(), s)

re.sub can take a function for the "replacement" (rather than just a string, which is the usage most people seem to be familiar with). This repl function will be called with an re.Match object for each match of the pattern, and the result (which should be a string) will be used as a replacement for that match.

A longer version of the same thing:

WORD_RE = re.compile(r'\w+')

def capitalizeMatch(m):
  return m.group(0).capitalize()

def capitalizeWords(s):
  return WORD_RE.sub(capitalizeMatch, s)

This pre-compiles the pattern (generally considered good form) and uses a named function instead of a lambda.

You are really asking a couple of questions here:

1) Why does the price of SSL certificates vary so much

2) Where can I get good, cheap SSL certificates?

The first question is a good one. For example, the type of SSL certificate you buy is important. Many SSL certificates are domain verified only - that is, the company issuing the certificate only validate that you own the domain. They don't validate your identity, so people visiting your site might know that the domain has a SSL certificate, but that doesn't mean the person behing the website isn't a scammer or phisher, for example. This is why the Verisign solution is much more expensive - you are getting a cert that not only secures your site, but validates the identity of the owner of the site (well, that's the claim).

You can read more on this subject here

For your second question, I can personally recommend RapidSSL. I've bought several certificates from them in the past and they are, well, rapid. However, you should always do your research first. A company based in France might be better for you to deal with as you can get support in your local hours, etc.

Try this:

export CURLNAME="john:@31&3*J"
curl -d -u "${CURLNAME}" https://www.example.com

Create a table view cell subclass and set it as the class of the prototype. Add the outlets to that class and connect them. Now when you configure the cell you can access the outlets.

Ready for copy and paste function for common use cases, improved/extended version of one answer above:

function getDirContents(string $dir, int $onlyFiles = 0, string $excludeRegex = '~/\.git/~', int $maxDepth = -1): array {
    $results = [];
    $scanAll = scandir($dir);
    sort($scanAll);
    $scanDirs = []; $scanFiles = [];
    foreach($scanAll as $fName){
        if ($fName === '.' || $fName === '..') { continue; }
        $fPath = str_replace(DIRECTORY_SEPARATOR, '/', realpath($dir . '/' . $fName));
        if (strlen($excludeRegex) > 0 && preg_match($excludeRegex, $fPath . (is_dir($fPath) ? '/' : ''))) { continue; }
        if (is_dir($fPath)) {
            $scanDirs[] = $fPath;
        } elseif ($onlyFiles >= 0) {
            $scanFiles[] = $fPath;
        }
    }

    foreach ($scanDirs as $pDir) {
        if ($onlyFiles <= 0) {
            $results[] = $pDir;
        }
        if ($maxDepth !== 0) {
            foreach (getDirContents($pDir, $onlyFiles, $excludeRegex, $maxDepth - 1) as $p) {
                $results[] = $p;
            }
        }
    }
    foreach ($scanFiles as $p) {
        $results[] = $p;
    }

    return $results;
}

And if you need relative paths:

function updateKeysWithRelPath(array $paths, string $baseDir, bool $allowBaseDirPath = false): array {
    $results = [];
    $regex = '~^' . preg_quote(str_replace(DIRECTORY_SEPARATOR, '/', realpath($baseDir)), '~') . '(?:/|$)~s';
    $regex = preg_replace('~/~', '/(?:(?!\.\.?/)(?:(?!/).)+/\.\.(?:/|$))?(?:\.(?:/|$))*', $regex); // limited to only one "/xx/../" expr
    if (DIRECTORY_SEPARATOR === '\\') {
        $regex = preg_replace('~/~', '[/\\\\\\\\]', $regex) . 'i';
    }
    foreach ($paths as $p) {
        $rel = preg_replace($regex, '', $p, 1);
        if ($rel === $p) {
            throw new \Exception('Path relativize failed, path "' . $p . '" is not within basedir "' . $baseDir . '".');
        } elseif ($rel === '') {
            if (!$allowBaseDirPath) {
                throw new \Exception('Path relativize failed, basedir path "' . $p . '" not allowed.');
            } else {
                $results[$rel] = './';
            }
        } else {
            $results[$rel] = $p;
        }
    }
    return $results;
}

function getDirContentsWithRelKeys(string $dir, int $onlyFiles = 0, string $excludeRegex = '~/\.git/~', int $maxDepth = -1): array {
    return updateKeysWithRelPath(getDirContents($dir, $onlyFiles, $excludeRegex, $maxDepth), $dir);
}

This version solves/improves:

1. warnings from realpath when PHP open_basedir does not cover the .. directory.
2. does not use reference for the result array
3. allows to exclude directories and files
4. allows to list files/directories only
5. allows to limit the search depth
6. it always sort output with directories first (so directories can be removed/emptied in reverse order)
7. allows to get paths with relative keys
8. heavy optimized for hundred of thousands or even milions of files
9. write for more in the comments :)

Examples:

// list only `*.php` files and skip .git/ and the current file
$onlyPhpFilesExcludeRegex = '~/\.git/|(?<!/|\.php)$|^' . preg_quote(str_replace(DIRECTORY_SEPARATOR, '/', realpath(__FILE__)), '~') . '$~is';

$phpFiles = getDirContents(__DIR__, 1, $onlyPhpFilesExcludeRegex);
print_r($phpFiles);

// with relative keys
$phpFiles = getDirContentsWithRelKeys(__DIR__, 1, $onlyPhpFilesExcludeRegex);
print_r($phpFiles);

// with "include only" regex to include only .html and .txt files with "/*_mails/en/*.(html|txt)" path
'~/\.git/|^(?!.*/(|' . '[^/]+_mails/en/[^/]+\.(?:html|txt)' . ')$)~is'

It's in the python docs.

import datetime
datetime.datetime.combine(datetime.date(2011, 1, 1), 
                          datetime.time(10, 23))

returns

datetime.datetime(2011, 1, 1, 10, 23)

To use foreach would require you have an array that contains every row from the query result. Some DB libraries for PHP provide a fetch_all function that provides an appropriate array but I could not find one for mysql (however the mysqli extension does) . You could of course write your own, like so

function mysql_fetch_all($result) {
   $rows = array();
   while ($row = mysql_fetch_array($result)) {
     $rows[] = $row;
   }
   return $rows;
}

However I must echo the "why?" Using this function you are creating two loops instead of one, and requring the entire result set be loaded in to memory. For sufficiently large result sets, this could become a serious performance drag. And for what?

foreach (mysql_fetch_all($result) as $row)

vs

while ($row = mysql_fetch_array($result))

while is just as concise and IMO more readable.

EDIT There is another option, but it is pretty absurd. You could use the Iterator Interface

class MysqlResult implements Iterator {
  private $rownum = 0;
  private $numrows = 0;
  private $result;

  public function __construct($result) {
    $this->result = $result;
    $this->numrows = mysql_num_rows($result);
  }

  public function rewind() {
    $this->rownum = 0;
  }

  public function current() {
    mysql_data_seek($this->result, $this->rownum);
    return mysql_fetch_array($this->result);
  }

  public function key() {
    return $this->rownum;
  }

  public function next() {
    $this->rownum++;
  }

  public function valid() {
    return $this->rownum < $this->numrows ? true : false;
  }
}

$rows = new MysqlResult(mysql_query($query_select));

foreach ($rows as $row) {
  //code...
}

In this case, the MysqlResult instance fetches rows only on request just like with while, but wraps it in a nice foreach-able package. While you've saved yourself a loop, you've added the overhead of class instantiation and a boat load of function calls, not to mention a good deal of added code complexity.

But you asked if it could be done without using while (or for I imagine). Well it can be done, just like that. Whether it should be done is up to you.

    public async Task<HttpResponseMessage> PostFormDataAsync()    //async is used for defining an asynchronous method
    {
        if (!Request.Content.IsMimeMultipartContent())

            throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);
        }
        var fileLocation = "";
        string root = HttpContext.Current.Server.MapPath("~/App_Data");
        MultipartFormDataStreamProvider provider = new MultipartFormDataStreamProvider(root);  //Helps in HTML file uploads to write data to File Stream
        try

            // Read the form data.
        await Request.Content.ReadAsMultipartAsync(provider);

            // This illustrates how to get the file names.
            foreach (MultipartFileData file in provider.FileData)
            {
                Trace.WriteLine(file.Headers.ContentDisposition.FileName); //Gets the file name
                var filePath = file.Headers.ContentDisposition.FileName.Substring(1, file.Headers.ContentDisposition.FileName.Length - 2); //File name without the path
                File.Copy(file.LocalFileName, file.LocalFileName + filePath); //Save a copy for reading it
                fileLocation = file.LocalFileName + filePath; //Complete file location
            }
    HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.OK, recordStatus);
            return response;
}

    {
            return Request.CreateErrorResponse(HttpStatusCode.InternalServerError, e);
    }
}
public void ReadFromExcel()

try
        {
            DataTable sheet1 = new DataTable();
            OleDbConnectionStringBuilder csbuilder = new OleDbConnectionStringBuilder();
            csbuilder.Provider = "Microsoft.ACE.OLEDB.12.0";
            csbuilder.DataSource = fileLocation;
            csbuilder.Add("Extended Properties", "Excel 12.0 Xml;HDR=YES");
            string selectSql = @"SELECT * FROM [Sheet1$]";
            using (OleDbConnection connection = new OleDbConnection(csbuilder.ConnectionString))
            using (OleDbDataAdapter adapter = new OleDbDataAdapter(selectSql, connection))
            {
                connection.Open();
                adapter.Fill(sheet1);
            }
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
        }          
}

And here is the one liner:

$("<li><div class='bar'>bla</div></li>").find("li").attr("id","1234").end().appendTo("body")

But I'm wondering why you would like to add the "id" attribute at a later stage rather than injecting it directly in the template.

The General Syntax of operator overloading in C++

You cannot change the meaning of operators for built-in types in C++, operators can only be overloaded for user-defined types¹. That is, at least one of the operands has to be of a user-defined type. As with other overloaded functions, operators can be overloaded for a certain set of parameters only once.

Not all operators can be overloaded in C++. Among the operators that cannot be overloaded are: . :: sizeof typeid .* and the only ternary operator in C++, ?:

Among the operators that can be overloaded in C++ are these:

• arithmetic operators: + - * / % and += -= *= /= %= (all binary infix); + - (unary prefix); ++ -- (unary prefix and postfix)
• bit manipulation: & | ^ << >> and &= |= ^= <<= >>= (all binary infix); ~ (unary prefix)
• boolean algebra: == != < > <= >= || && (all binary infix); ! (unary prefix)
• memory management: new new[] delete delete[]
• implicit conversion operators
• miscellany: = [] -> ->* , (all binary infix); * & (all unary prefix) () (function call, n-ary infix)

However, the fact that you can overload all of these does not mean you should do so. See the basic rules of operator overloading.

In C++, operators are overloaded in the form of functions with special names. As with other functions, overloaded operators can generally be implemented either as a member function of their left operand's type or as non-member functions. Whether you are free to choose or bound to use either one depends on several criteria.² A unary operator @³, applied to an object x, is invoked either as operator@(x) or as x.operator@(). A binary infix operator @, applied to the objects x and y, is called either as operator@(x,y) or as x.operator@(y).⁴

Operators that are implemented as non-member functions are sometimes friend of their operand’s type.

¹ _{The term “user-defined” might be slightly misleading. C++ makes the distinction between built-in types and user-defined types. To the former belong for example int, char, and double; to the latter belong all struct, class, union, and enum types, including those from the standard library, even though they are not, as such, defined by users.}

² _{This is covered in a later part of this FAQ.}

³ _{The @ is not a valid operator in C++ which is why I use it as a placeholder.}

⁴ _{The only ternary operator in C++ cannot be overloaded and the only n-ary operator must always be implemented as a member function.}

If adding an extra column with the hyperlinks is not an option, the alternative is to use an external editor to enclose your hyperlink into =hyperlink(" and "), in order to obtain =hyperlink("originalCellContent")

If you have Notepad++, this is a recipe you can use to perform this operation semi-automatically:

• Copy the column of addresses to Notepad++
• Keeping ALT-SHIFT pressed, extended your cursor from the top left corner to the bottom left corner, and type =hyperlink(". This adds =hyperlink(" at the beginning of each entry.
• Open "Replace" menu (Ctrl-H), activate regular expressions (ALT-G), and replace $ (end of line) with "\). This adds a closed quote and a closed parenthesis (which needs to be escaped with \ when regular expressions are activated) at the end of each line.
• Paste back the data in Excel. In practice, just copy the data and select the first cell of the column where you want the data to end up.

To remove all the documents in all the collections:

db.getCollectionNames().forEach( function(collection_name) { 
    if (collection_name.indexOf("system.") == -1) {
        print ( ["Removing: ", db[collection_name].count({}), " documents from ", collection_name].join('') );
        db[collection_name].remove({}); 
    }
});

This worked for me. Hope it helps someone. :)

SimpleAdapter adapter = (SimpleAdapter) getListAdapter();
this.resultsList.remove((int) info.id);
adapter.notifyDataSetChanged();

Is this what you are after? Just index the element and assign a new value.

I agree with Mutanos and Alecio. Further, one can check as many identical method calls as possible (verifying the subsequent calls in the production code, the order of the verify's does not matter). Here is the code:

import static org.mockito.AdditionalMatchers.*;

    verify(mockObject).myMethod(aryEq(new byte[] { 0 }));
    verify(mockObject).myMethod(aryEq(new byte[] { 1, 2 }));

        } else if (amount >= 1_000) {
            suffixIndex = 1;
        } else {
            suffixIndex = 0;
        }

        int quotient;
        int remainder;
        if (amount >= 1_000_000) {
            quotient = amount / 1_000_000;
            remainder = amount % 1_000_000;
        } else if (amount >= 1_000) {
            quotient = amount / 1_000;
            remainder = amount % 1_000;
        } else {
            return String.valueOf(amount);
        }

        if (remainder == 0) {
            return String.valueOf(quotient) + suffix[suffixIndex];
        }

        // Keep two most significant digits
        if (remainder >= 10_000) {
            remainder /= 10_000;
        } else if (remainder >= 1_000) {
            remainder /= 1_000;
        } else if (remainder >= 100) {
            remainder /= 10;
        }

        return String.valueOf(quotient) + '.' + String.valueOf(remainder) + suffix[suffixIndex];
    }
}

This is my test class (based on Junit 4):

public class CurrencyUtilsTest {

    @Test
    public void getCompactStringForDisplay() throws Exception {
        int[] numbers = {0, 5, 999, 1_000, 5_821, 10_500, 101_800, 2_000_000, 7_800_000, 92_150_000, 123_200_000, 9_999_999};
        String[] expected = {"0", "5", "999", "1K", "5.82K", "10.50K", "101.80K", "2M", "7.80M", "92.15M", "123.20M", "9.99M"};

        for (int i = 0; i < numbers.length; i++) {
            int n = numbers[i];
            String formatted = CurrencyUtils.getCompactStringForDisplay(n);
            System.out.println(n + " => " + formatted);

            assertEquals(expected[i], formatted);
        }
    }

}

Generally a parameter is what appears in the definition of the method. An argument is the instance passed to the method during runtime.

You can see a description here: http://en.wikipedia.org/wiki/Parameter_(computer_programming)#Parameters_and_arguments

String payloadRequest = getBody(request);

Using this method

public static String getBody(HttpServletRequest request) throws IOException {

    String body = null;
    StringBuilder stringBuilder = new StringBuilder();
    BufferedReader bufferedReader = null;

    try {
        InputStream inputStream = request.getInputStream();
        if (inputStream != null) {
            bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
            char[] charBuffer = new char[128];
            int bytesRead = -1;
            while ((bytesRead = bufferedReader.read(charBuffer)) > 0) {
                stringBuilder.append(charBuffer, 0, bytesRead);
            }
        } else {
            stringBuilder.append("");
        }
    } catch (IOException ex) {
        throw ex;
    } finally {
        if (bufferedReader != null) {
            try {
                bufferedReader.close();
            } catch (IOException ex) {
                throw ex;
            }
        }
    }

    body = stringBuilder.toString();
    return body;
}

While none of these answers worked for me, I was able to fix the issue using the following command.

git fetch origin

This did a trick for me.

You need to modify the method GetData() and add your "experimental" code there, and return t1.

Check that All Files are Included in Your Project:

I had this same error pop up after I updated cLion. After hours of tinkering, I noticed one of my files was not included in the project target. After I added it back to the active project, I stopped getting the undefined reference to winmain16, and the code compiled.

Edit: It's also worthwhile to check the build settings within your IDE.

(Not sure if this error is related to having recently updated the IDE - could be causal or simply correlative. Feel free to comment with any insight on that factor!)

And you can combine same events/functions in this way:

$("table.planning_grid").on({
    mouseenter: function() {
        // Handle mouseenter...
    },
    mouseleave: function() {
        // Handle mouseleave...
    },
    'click blur paste' : function() {
        // Handle click...
    }
}, "input");

Because textContent is not supported in IE8 and older, here is a workaround:

var node = document.getElementById('test'),
var text  = node.textContent || node.innerText;
alert(text);

innerText does work in IE.

The trouble with DateTime.UtcNow and DateTime.Now is that, depending on the computer and operating system, it may only be accurate to between 10 and 15 milliseconds. However, on windows computers one can use by using the low level function GetSystemTimePreciseAsFileTime to get microsecond accuracy, see the function GetTimeStamp() below.

    [System.Security.SuppressUnmanagedCodeSecurity, System.Runtime.InteropServices.DllImport("kernel32.dll")]
    static extern void GetSystemTimePreciseAsFileTime(out FileTime pFileTime);

    [System.Runtime.InteropServices.StructLayout(System.Runtime.InteropServices.LayoutKind.Sequential)]
    public struct FileTime  {
        public const long FILETIME_TO_DATETIMETICKS = 504911232000000000;   // 146097 = days in 400 year Gregorian calendar cycle. 504911232000000000 = 4 * 146097 * 86400 * 1E7
        public uint TimeLow;    // least significant digits
        public uint TimeHigh;   // most sifnificant digits
        public long TimeStamp_FileTimeTicks { get { return TimeHigh * 4294967296 + TimeLow; } }     // ticks since 1-Jan-1601 (1 tick = 100 nanosecs). 4294967296 = 2^32
        public DateTime dateTime { get { return new DateTime(TimeStamp_FileTimeTicks + FILETIME_TO_DATETIMETICKS); } }
    }

    public static DateTime GetTimeStamp() { 
        FileTime ft; GetSystemTimePreciseAsFileTime(out ft);
        return ft.dateTime;
    }

I tried to solve this issue.

My answer is here.

"DynamicHeader" - http://dynamicheader.codeplex.com/, https://nuget.org/packages/DynamicHeader

For example, _Layout.cshtml is:

<head>
@Html.DynamicHeader()
</head>
...

And, you can register .js and .css files to "DynamicHeader" anywhere you want.

For example, the code block in AnotherPartial.cshtml is:

@{
  DynamicHeader.AddSyleSheet("~/Content/themes/base/AnotherPartial.css");
  DynamicHeader.AddScript("~/some/myscript.js");
}

Result HTML output for this sample is:

<html>
  <link href="/myapp/Content/themes/base/AnotherPartial.css" .../>
  <script src="/myapp/some/myscript.js" ...></script>
</html>
...

Try this:

li.setBackgroundColor(android.R.color.red); //or which ever color do you want

EDIT: Posting logcat file would also help.

Deleting duplicates on MySQL tables is a common issue, that's genarally the result of a missing constraint to avoid those duplicates before hand. But this common issue usually comes with specific needs... that do require specific approaches. The approach should be different depending on, for example, the size of the data, the duplicated entry that should be kept (generally the first or the last one), whether there are indexes to be kept, or whether we want to perform any additional action on the duplicated data.

There are also some specificities on MySQL itself, such as not being able to reference the same table on a FROM cause when performing a table UPDATE (it'll raise MySQL error #1093). This limitation can be overcome by using an inner query with a temporary table (as suggested on some approaches above). But this inner query won't perform specially well when dealing with big data sources.

However, a better approach does exist to remove duplicates, that's both efficient and reliable, and that can be easily adapted to different needs.

The general idea is to create a new temporary table, usually adding a unique constraint to avoid further duplicates, and to INSERT the data from your former table into the new one, while taking care of the duplicates. This approach relies on simple MySQL INSERT queries, creates a new constraint to avoid further duplicates, and skips the need of using an inner query to search for duplicates and a temporary table that should be kept in memory (thus fitting big data sources too).

This is how it can be achieved. Given we have a table employee, with the following columns:

employee (id, first_name, last_name, start_date, ssn)

In order to delete the rows with a duplicate ssn column, and keeping only the first entry found, the following process can be followed:

-- create a new tmp_eployee table
CREATE TABLE tmp_employee LIKE employee;

-- add a unique constraint
ALTER TABLE tmp_employee ADD UNIQUE(ssn);

-- scan over the employee table to insert employee entries
INSERT IGNORE INTO tmp_employee SELECT * FROM employee ORDER BY id;

-- rename tables
RENAME TABLE employee TO backup_employee, tmp_employee TO employee;

Technical explanation

• Line #1 creates a new tmp_eployee table with exactly the same structure as the employee table
• Line #2 adds a UNIQUE constraint to the new tmp_eployee table to avoid any further duplicates
• Line #3 scans over the original employee table by id, inserting new employee entries into the new tmp_eployee table, while ignoring duplicated entries
• Line #4 renames tables, so that the new employee table holds all the entries without the duplicates, and a backup copy of the former data is kept on the backup_employee table

? Using this approach, 1.6M registers were converted into 6k in less than 200s.

Chetan, following this process, you could fast and easily remove all your duplicates and create a UNIQUE constraint by running:

CREATE TABLE tmp_jobs LIKE jobs;

ALTER TABLE tmp_jobs ADD UNIQUE(site_id, title, company);

INSERT IGNORE INTO tmp_jobs SELECT * FROM jobs ORDER BY id;

RENAME TABLE jobs TO backup_jobs, tmp_jobs TO jobs;

Of course, this process can be further modified to adapt it for different needs when deleting duplicates. Some examples follow.

? Variation for keeping the last entry instead of the first one

Sometimes we need to keep the last duplicated entry instead of the first one.

CREATE TABLE tmp_employee LIKE employee;

ALTER TABLE tmp_employee ADD UNIQUE(ssn);

INSERT IGNORE INTO tmp_employee SELECT * FROM employee ORDER BY id DESC;

RENAME TABLE employee TO backup_employee, tmp_employee TO employee;

• On line #3, the ORDER BY id DESC clause makes the last ID's to get priority over the rest

? Variation for performing some tasks on the duplicates, for example keeping a count on the duplicates found

Sometimes we need to perform some further processing on the duplicated entries that are found (such as keeping a count of the duplicates).

CREATE TABLE tmp_employee LIKE employee;

ALTER TABLE tmp_employee ADD UNIQUE(ssn);

ALTER TABLE tmp_employee ADD COLUMN n_duplicates INT DEFAULT 0;

INSERT INTO tmp_employee SELECT * FROM employee ORDER BY id ON DUPLICATE KEY UPDATE n_duplicates=n_duplicates+1;

RENAME TABLE employee TO backup_employee, tmp_employee TO employee;

• On line #3, a new column n_duplicates is created
• On line #4, the INSERT INTO ... ON DUPLICATE KEY UPDATE query is used to perform an additional update when a duplicate is found (in this case, increasing a counter) The INSERT INTO ... ON DUPLICATE KEY UPDATE query can be used to perform different types of updates for the duplicates found.

? Variation for regenerating the auto-incremental field id

Sometimes we use an auto-incremental field and, in order the keep the index as compact as possible, we can take advantage of the deletion of the duplicates to regenerate the auto-incremental field in the new temporary table.

CREATE TABLE tmp_employee LIKE employee;

ALTER TABLE tmp_employee ADD UNIQUE(ssn);

INSERT IGNORE INTO tmp_employee SELECT (first_name, last_name, start_date, ssn) FROM employee ORDER BY id;

RENAME TABLE employee TO backup_employee, tmp_employee TO employee;

• On line #3, instead of selecting all the fields on the table, the id field is skipped so that the DB engine generates a new one automatically

? Further variations

Many further modifications are also doable depending on the desired behavior. As an example, the following queries will use a second temporary table to, besides 1) keep the last entry instead of the first one; and 2) increase a counter on the duplicates found; also 3) regenerate the auto-incremental field id while keeping the entry order as it was on the former data.

CREATE TABLE tmp_employee LIKE employee;

ALTER TABLE tmp_employee ADD UNIQUE(ssn);

ALTER TABLE tmp_employee ADD COLUMN n_duplicates INT DEFAULT 0;

INSERT INTO tmp_employee SELECT * FROM employee ORDER BY id DESC ON DUPLICATE KEY UPDATE n_duplicates=n_duplicates+1;

CREATE TABLE tmp_employee2 LIKE tmp_employee;

INSERT INTO tmp_employee2 SELECT (first_name, last_name, start_date, ssn) FROM tmp_employee ORDER BY id;

DROP TABLE tmp_employee;

RENAME TABLE employee TO backup_employee, tmp_employee2 TO employee;

JSON is a format that encodes objects in a string. Serialization means to convert an object into that string, and deserialization is its inverse operation (convert string -> object).

When transmitting data or storing them in a file, the data are required to be byte strings, but complex objects are seldom in this format. Serialization can convert these complex objects into byte strings for such use. After the byte strings are transmitted, the receiver will have to recover the original object from the byte string. This is known as deserialization.

Say, you have an object:

{foo: [1, 4, 7, 10], bar: "baz"}

serializing into JSON will convert it into a string:

'{"foo":[1,4,7,10],"bar":"baz"}'

which can be stored or sent through wire to anywhere. The receiver can then deserialize this string to get back the original object. {foo: [1, 4, 7, 10], bar: "baz"}.

Maybe this could be useful:

def Retriever(bar):
    return (list(globals().keys()))[list(map(lambda x: id(x), list(globals().values()))).index(id(bar))]

The function goes through the list of IDs of values from the global scope (the namespace could be edited), finds the index of the wanted/required var or function based on its ID, and then returns the name from the list of global names based on the acquired index.

Use css:

<style>
input[name=btnsubmit]:active {
color: green;
}
</style>

Follow these steps to upload your project to Github

1) git init

2) git add .

3) git commit -m "Add all my files"

4) git remote add origin https://github.com/yourusername/your-repo-name.git

Upload of project from scratch require git pull origin master.

5) git pull origin master

6) git push origin master

If any problem occurs in pushing use git push --force origin master

#1- Run this to configure the region once and for all:

aws configure set region us-east-1 --profile admin

• Change admin next to the profile if it's different.

• Change us-east-1 if your region is different.

#2- Run your command again:

aws ecs list-container-instances --cluster default

As Ian said, the solution is to nest the table inside a div and set it like that:

.table_wrapper {
  border-radius: 5px;
  overflow: hidden;
}

With overflow:hidden, the square corners won't bleed through the div.

to avoid the problem with CDROM: sudo nano /etc/apt/sources.list

find your cdrom and comment it with #

save the changes: "cntrl + o", than exit the file: "cntrl + x"

and try to install again

As a start there is no need to do a ps -aux | grep... The command pidof is far better to use. And almost never ever do kill -9 see here

to get the output from a command in bash, use something like

pid=$(pidof ruby)

or use pkill directly.

If you use the CMake GUI then swap to the advanced view and then the option is called CMAKE_VERBOSE_MAKEFILE.

did you try this

{% load games_tags %} 

at the top instead of pygmentize?

CKEDITOR.config.enterMode = CKEDITOR.ENTER_BR; - this works perfectly for me. Have you tried clearing your browser cache - this is an issue sometimes.
You can also check it out with the jQuery adapter:

<script type="text/javascript" src="/js/ckeditor/ckeditor.js"></script>
<script type="text/javascript" src="/js/ckeditor/adapters/jquery.js"></script>
<script type="text/javascript">
$(function() {
    $('#your_textarea').ckeditor({
        toolbar: 'Full',
        enterMode : CKEDITOR.ENTER_BR,
        shiftEnterMode: CKEDITOR.ENTER_P
    });
});
</script>

UPDATE according to @Tomkay's comment:

Since version 3.6 of CKEditor you can configure if you want inline content to be automatically wrapped with tags like <p></p>. This is the correct setting:

CKEDITOR.config.autoParagraph = false;

Source: http://docs.cksource.com/ckeditor_api/symbols/CKEDITOR.config.html#.autoParagraph

tl;dr: For modern browsers, just use

input.value = '';

Old answer:

How about:

input.type = "text";
input.type = "file";

I still have to understand why this does not work with webkit.

Anyway, this works with IE9>, Firefox and Opera.
The situation with webkit is that I seem to be unable to change it back to file.
With IE8, the situation is that it throws a security exception.

Edit: For webkit, Opera and firefox this works, though:

input.value = '';

(check the above answer with this proposal)

I'll see if I can find a nice cleaner way of doing this cross-browser without the need of the GC.

Edit2:

try{
    inputs[i].value = '';
    if(inputs[i].value){
        inputs[i].type = "text";
        inputs[i].type = "file";
    }
}catch(e){}

Works with most browsers. Does not work with IE < 9, that's all.
Tested on firefox 20, chrome 24, opera 12, IE7, IE8, IE9, and IE10.

in my case, I was passing all the parameters but one of the parameter my code was passing a null value for string.

Eg: cmd.Parameters.AddWithValue("@userName", userName);

in the above case, if the data type of userName is string, I was passing userName as null.

This is from Apple doc

Classes and structures must set all of their stored properties to an appropriate initial value by the time an instance of that class or structure is created. Stored properties cannot be left in an indeterminate state.

You get the error message Class "HomeCell" has no initializers because your variables is in an indeterminate state. Either you create initializers or you make them optional types, using ! or ?

Find repoName from the url, and then checkout to the specified directory.

String url = 'https://github.com/foo/bar.git';
String[] res = url.split('/');
String repoName = res[res.length-1];
if (repoName.endsWith('.git')) repoName=repoName.substring(0, repoName.length()-4);

checkout([
  $class: 'GitSCM', 
  branches: [[name: 'refs/heads/'+env.BRANCH_NAME]],
  doGenerateSubmoduleConfigurations: false,
  extensions: [
    [$class: 'RelativeTargetDirectory', relativeTargetDir: repoName],
    [$class: 'GitLFSPull'],
    [$class: 'CheckoutOption', timeout: 20],
    [$class: 'CloneOption',
        depth: 3,
        noTags: false,
        reference: '/other/optional/local/reference/clone',
        shallow: true,
        timeout: 120],
    [$class: 'SubmoduleOption', depth: 5, disableSubmodules: false, parentCredentials: true, recursiveSubmodules: true, reference: '', shallow: true, trackingSubmodules: true]
  ],
  submoduleCfg: [],
  userRemoteConfigs: [

The keypress event isn't triggered by all browsers when you click shift or ctrl, but fortunately the keydown event is.

If you switch out the keypress with keydown you might have better luck.

In Eclipse, Go to your class, Right click->source->Generate toString();

It will override the toString() method and will print the object of that class.

With Ajax, for me worked:

Html:

<div id='anID'>
 <form name="nameOfForm">
            <p><b>Your headline</b></p>
            <input type='radio' name='nameOfRadio' value='seed' 
             <?php if ($interviewStage == 'seed') {echo" checked ";}?> 
            onchange='funcInterviewStage()'><label>Your label</label><br>
 </form>
</div>

Javascript:

 function funcInterviewStage() {

                var dis = document.nameOfForm.nameOfRadio.value;

                //Auswahltafel anzeigen
                  if (dis == "") {
                      document.getElementById("anID").innerHTML = "";
                      return;
                  } else { 
                      if (window.XMLHttpRequest) {
                          // code for IE7+, Firefox, Chrome, Opera, Safari
                          xmlhttp = new XMLHttpRequest();
                      } else {
                          // code for IE6, IE5
                          xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
                      }
                      xmlhttp.onreadystatechange = function() {
                          if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                              document.getElementById("anID").innerHTML = xmlhttp.responseText;
                          }
                      }
                      xmlhttp.open("GET","/includes/[name].php?id="+dis,true);
                      xmlhttp.send();
                  }
              }  

And php:

//// Get Value
$id = mysqli_real_escape_string($db, $_GET['id']);

//// Insert to database
$insert = mysqli_query($db, "UPDATE [TABLE] SET [column] = '$id' WHERE [...]");

//// Show radio buttons again
$mysqliAbfrage = mysqli_query($db, "SELECT [column] FROM [Table] WHERE [...]");
                  while ($row = mysqli_fetch_object($mysqliAbfrage)) {
                    ...
                  }
                  echo" 
                  <form name='nameOfForm'>
                      <p><b>Your headline</b></p>
                      <input type='radio' name='nameOfRadio' value='seed'"; if ($interviewStage == 'seed') {echo" checked ";} echo" onchange='funcInterviewStage()'><label>Yourr Label</label><br>
                      <input type='radio' name='nameOfRadio' value='startup'"; if ($interviewStage == 'startup') {echo" checked ";} echo" onchange='funcInterviewStage()'><label>Your label</label><br>

                  </form> ";

Actually a more refined solution is use the build-in function sumif, this function does exactly what you need, will only sum those expenses of a specified month.

example

=SUMIF(A2:A100,"=January",B2:B100)

Answer in Swift 5 (Continuation of Ricky's answer in Swift)

Add the UIGestureRecognizerDelegate to your ViewController

 override func viewDidLoad() {
    super.viewDidLoad()

    //Long Press
    let longPressGesture = UILongPressGestureRecognizer(target: self, action: #selector(handleLongPress))
    longPressGesture.minimumPressDuration = 0.5
    self.tableView.addGestureRecognizer(longPressGesture)
 }

And the function:

@objc func handleLongPress(longPressGesture: UILongPressGestureRecognizer) {
    let p = longPressGesture.location(in: self.tableView)
    let indexPath = self.tableView.indexPathForRow(at: p)
    if indexPath == nil {
        print("Long press on table view, not row.")
    } else if longPressGesture.state == UIGestureRecognizer.State.began {
        print("Long press on row, at \(indexPath!.row)")
    }
}

I've been using this trick for several years and it works perfectly without any problem for checked/unchecked checkbox status while using with PHP and Database.

HTML Code: (for Add Page)

<input name="status" type="checkbox" value="1" checked>

Hint: remove "checkbox" if you want to show it as unchecked by default

HTML Code: (for Edit Page)

<input name="status" type="checkbox" value="1" 
<?php if ($row['status'] == 1) { echo "checked='checked'"; } ?>>

PHP Code: (use for Add/Edit pages)

$status = $_POST['status'];
if ($status == 1) {
$status = 1;
} else {
$status = 0;
}

Hint: There will always be empty value unless user checked it. So, we already have PHP code to catch it else keep the value to 0. Then, simply use the $status variable for database.

[] denotes a list, () denotes a tuple and {} denotes a dictionary. You should take a look at the official Python tutorial as these are the very basics of programming in Python.

What you have is a list of strings. You can sort it like this:

In [1]: lst = ['Stem', 'constitute', 'Sedge', 'Eflux', 'Whim', 'Intrigue']

In [2]: sorted(lst)
Out[2]: ['Eflux', 'Intrigue', 'Sedge', 'Stem', 'Whim', 'constitute']

As you can see, words that start with an uppercase letter get preference over those starting with a lowercase letter. If you want to sort them independently, do this:

In [4]: sorted(lst, key=str.lower)
Out[4]: ['constitute', 'Eflux', 'Intrigue', 'Sedge', 'Stem', 'Whim']

You can also sort the list in reverse order by doing this:

In [12]: sorted(lst, reverse=True)
Out[12]: ['constitute', 'Whim', 'Stem', 'Sedge', 'Intrigue', 'Eflux']

In [13]: sorted(lst, key=str.lower, reverse=True)
Out[13]: ['Whim', 'Stem', 'Sedge', 'Intrigue', 'Eflux', 'constitute']

Please note: If you work with Python 3, then str is the correct data type for every string that contains human-readable text. However, if you still need to work with Python 2, then you might deal with unicode strings which have the data type unicode in Python 2, and not str. In such a case, if you have a list of unicode strings, you must write key=unicode.lower instead of key=str.lower.

As a variation on Levik's answer that allows you to find also the ids of the duplicate results, I used the following:

SELECT * FROM table1 WHERE column1 IN (SELECT column1 AS duplicate_value FROM table1 GROUP BY column1 HAVING COUNT(*) > 1)

Friend, don't worry, if you have any application installed built in codeigniter and you wanna add some language pack just follow these steps:

1. Add language files in folder application/language/arabic (i add arabic lang in sma2 built in ci)

2. Go to the file named setting.php in application/modules/settings/views/setting.php. Here you find the array

<?php /*

 $lang = array (
  'english' => 'English',

  'arabic' => 'Arabic',  // i add this here

  'spanish' => 'Español'

Now save and run the application. It's worked fine.

In most of cases it is data log problem. Follow the steps.

i) Go to data folder of mysql. For xampp go to C:\xampp\mysql\data.

ii) Look for log file name like ib_logfile0 and ib_logfile1.

iii) Create backup and delete those files.

iv) Restart apache and mysql.

    //create TreeMap instance
    TreeMap treeMap = new TreeMap();

    //add key value pairs to TreeMap
    treeMap.put("1","One");
    treeMap.put("2","Two");
    treeMap.put("3","Three");

    /*
      get Collection of values contained in TreeMap using
      Collection values()        
    */
    Collection c = treeMap.values();

    //obtain an Iterator for Collection
    Iterator itr = c.iterator();

    //iterate through TreeMap values iterator
    while(itr.hasNext())
      System.out.println(itr.next());

or:

   for (Map.Entry<K,V> entry : treeMap.entrySet()) {
        V value = entry.getValue();
        K key = entry.getKey();
   }

or:

   // Use iterator to display the keys and associated values
   System.out.println("Map Values Before: ");
   Set keys = map.keySet();
   for (Iterator i = keys.iterator(); i.hasNext();) {
     Integer key = (Integer) i.next();
     String value = (String) map.get(key);
     System.out.println(key + " = " + value);
   }

Symlinked directories:

It's important to note what happens when there is a directory which is a soft link. Any Git pull with an update removes the link and makes it a normal directory. This is what I learnt hard way. Some insights here and here.

Example

Before

 ls -l
 lrwxrwxrwx 1 admin adm   29 Sep 30 15:28 src/somedir -> /mnt/somedir

git add/commit/push

It remains the same

After git pull AND some updates found

 drwxrwsr-x 2 admin adm 4096 Oct  2 05:54 src/somedir

1. List item

public class ListBoxMultiple {

public static void main(String[] args) throws InterruptedException {
    // TODO Auto-generated method stub
    System.setProperty("webdriver.chrome.driver", "./drivers/chromedriver.exe");
    WebDriver driver=new ChromeDriver();
    driver.get("file:///C:/Users/Amitabh/Desktop/hotel2.html");//open the website
    driver.manage().window().maximize();


    WebElement hotel = driver.findElement(By.id("maarya"));//get the element

    Select sel=new Select(hotel);//for handling list box
    //isMultiple
    if(sel.isMultiple()){
        System.out.println("it is multi select list");
    }
    else{
        System.out.println("it is single select list");
    }
    //select option
    sel.selectByIndex(1);// you can select by index values
    sel.selectByValue("p");//you can select by value
    sel.selectByVisibleText("Fish");// you can also select by visible text of the options
    //deselect option but this is possible only in case of multiple lists
    Thread.sleep(1000);
    sel.deselectByIndex(1);
    sel.deselectAll();

    //getOptions
    List<WebElement> options = sel.getOptions();

    int count=options.size();
    System.out.println("Total options: "+count);

    for(WebElement opt:options){ // getting text of every elements
        String text=opt.getText();
        System.out.println(text);
        }

    //select all options
    for(int i=0;i<count;i++){
        sel.selectByIndex(i);
        Thread.sleep(1000);
    }

    driver.quit();

}

}

if you build an MVC project, its included by default. otherwise, what Nick said.

I just found this same problem. What I did was uninstall rbenv (via homebrew) and reinstall it. I also added

if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi

into ~/.bash_profile when I reinstalled rbenv. Works perfectly now.

IMHO __call__ method and closures give us a natural way to create STRATEGY design pattern in Python. We define a family of algorithms, encapsulate each one, make them interchangeable and in the end we can execute a common set of steps and, for example, calculate a hash for a file.

Adding the tomcat server in the server runtime will do the job :

Project Properties-> Java Build Path-> Add Library -> Select "Server Runtime" from the list-> Next->Select "Apache Tomcat"-> Finish

However, the previous answer could still be confusing for some programmers. Most especially beginners who are most probably using an older book or tutorial. Or perhaps you still feel the facade is needed. Sure you can use it. Me for one I still love to use the facade, this is because some times while building my api I forget to use the '\' before the Response.

if you are like me, simply add

   "use Response;"

above your class ...extends contoller. this should do.

with this you can now use:

$response = Response::json($posts, 200);

instead of:

$response = \Response::json($posts, 200);

Try putting your image into a container like so:

HTML:

<div>
    <img src="http://www.testimoniesofheavenandhell.com/Animal-Pictures/wp-content/uploads/2013/04/Dog-Animal-Picture-Siberian-Husky-Puppy-HD-Wallpaper.jpg" />
</div>

CSS:

div
{
    width: 200px;
    height: 200px;
    overflow: hidden;
}

div > img
{
    width: 300px;
}

Here's a fiddle.

This is not possible directly, because chronologically, WHERE happens before SELECT, which always is the last step in the execution chain.

You can do a sub-select and filter on it:

SELECT * FROM
(
  SELECT A.identifier
    , A.name
    , TO_NUMBER(DECODE( A.month_no
      , 1, 200803 
      , 2, 200804 
      , 3, 200805 
      , 4, 200806 
      , 5, 200807 
      , 6, 200808 
      , 7, 200809 
      , 8, 200810 
      , 9, 200811 
      , 10, 200812 
      , 11, 200701 
      , 12, 200702
      , NULL)) as MONTH_NO
    , TO_NUMBER(TO_CHAR(B.last_update_date, 'YYYYMM')) as UPD_DATE
  FROM table_a A
    , table_b B
  WHERE A.identifier = B.identifier
) AS inner_table
WHERE 
  MONTH_NO > UPD_DATE

Interesting bit of info moved up from the comments:

There should be no performance hit. Oracle does not need to materialize inner queries before applying outer conditions -- Oracle will consider transforming this query internally and push the predicate down into the inner query and will do so if it is cost effective. – Justin Cave

Yes.

$('a[href=\'http://google.com\']')

http://api.jquery.com/attribute-equals-selector/

On terminal type mvn -v and the output will look like the image shown below

You can also use Chocolatey.

Having it installed, just run:

choco install make

When it finishes, it is installed and available in Git for Bash / MinGW.

Use this static method, from anywhere (Activity / Fragment) you like.

public static void hideKeyboard(Activity activity) {
    try{
        InputMethodManager inputManager = (InputMethodManager) activity
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        View currentFocusedView = activity.getCurrentFocus();
        if (currentFocusedView != null) {
            inputManager.hideSoftInputFromWindow(currentFocusedView.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
        }
    }catch (Exception e){
        e.printStackTrace();
    }
}

If you want to use for fragment just call hideKeyboard(((Activity) getActivity())).

tl;dr — There's a summary at the end and headings in the answer to make it easier to find the relevant parts. Reading everything is recommended though as it provides useful background for understanding the why that makes seeing how the how applies in different circumstances easier.

About the Same Origin Policy

This is the Same Origin Policy. It is a security feature implemented by browsers.

Your particular case is showing how it is implemented for XMLHttpRequest (and you'll get identical results if you were to use fetch), but it also applies to other things (such as images loaded onto a <canvas> or documents loaded into an <iframe>), just with slightly different implementations.

(Weirdly, it also applies to CSS fonts, but that is because found foundries insisted on DRM and not for the security issues that the Same Origin Policy usually covers).

The standard scenario that demonstrates the need for the SOP can be demonstrated with three characters:

• Alice is a person with a web browser
• Bob runs a website (https://www.[website].com/ in your example)
• Mallory runs a website (http://localhost:4300 in your example)

Alice is logged into Bob's site and has some confidential data there. Perhaps it is a company intranet (accessible only to browsers on the LAN), or her online banking (accessible only with a cookie you get after entering a username and password).

Alice visits Mallory's website which has some JavaScript that causes Alice's browser to make an HTTP request to Bob's website (from her IP address with her cookies, etc). This could be as simple as using XMLHttpRequest and reading the responseText.

The browser's Same Origin Policy prevents that JavaScript from reading the data returned by Bob's website (which Bob and Alice don't want Mallory to access). (Note that you can, for example, display an image using an <img> element across origins because the content of the image is not exposed to JavaScript (or Mallory) … unless you throw canvas into the mix in which case you will generate a same-origin violation error).

Why the Same Origin Policy applies when you don't think it should

For any given URL it is possible that the SOP is not needed. A couple of common scenarios where this is the case are:

• Alice, Bob and Mallory are the same person.
• Bob is providing entirely public information

… but the browser has no way of knowing if either of the above are true, so trust is not automatic and the SOP is applied. Permission has to be granted explicitly before the browser will give the data it was given to a different website.

Why the Same Origin Policy only applies to JavaScript in a web page

Browser extensions*, the Network tab in browser developer tools and applications like Postman are installed software. They aren't passing data from one website to the JavaScript belonging to a different website just because you visited that different website. Installing software usually takes a more conscious choice.

There isn't a third party (Mallory) who is considered a risk.

* Browser extensions do need to be written carefully to avoid cross-origin issues. See the Chrome documentation for example.

Why you can display data in the page without reading it with JS

There are a number of circumstances where Mallory's site can cause a browser to fetch data from a third party and display it (e.g. by adding an <img> element to display an image). It isn't possible for Mallory's JavaScript to read the data in that resource though, only Alice's browser and Bob's server can do that, so it is still secure.

CORS

The Access-Control-Allow-Origin HTTP response header referred to in the error message is part of the CORS standard which allows Bob to explicitly grant permission to Mallory's site to access the data via Alice's browser.

A basic implementation would just include:

Access-Control-Allow-Origin: *

… in the response headers to permit any website to read the data.

Access-Control-Allow-Origin: http://example.com/

… would allow only a specific site to access it, and Bob can dynamically generate that based on the Origin request header to permit multiple, but not all, sites to access it.

The specifics of how Bob sets that response header depend on Bob's HTTP server and/or server-side programming language. There is a collection of guides for various common configurations that might help.

NB: Some requests are complex and send a preflight OPTIONS request that the server will have to respond to before the browser will send the GET/POST/PUT/Whatever request that the JS wants to make. Implementations of CORS that only add Access-Control-Allow-Origin to specific URLs often get tripped up by this.

Obviously granting permission via CORS is something Bob would only do only if either:

• The data was not private or
• Mallory was trusted

But I'm not Bob!

There is no standard mechanism for Mallory to add this header because it has to come from Bob's website, which she does not control.

If Bob is running a public API then there might be a mechanism to turn on CORS (perhaps by formatting the request in a certain way, or a config option after logging into a Developer Portal site for Bob's site). This will have to be a mechanism implemented by Bob though. Mallory could read the documentation on Bob's site to see if something is available, or she could talk to Bob and ask him to implement CORS.

Error messages which mention "Response for preflight"

Some cross origin requests are preflighted.

This happens when (roughly speaking) you try to make a cross-origin request that:

• Includes credentials like cookies
• Couldn't be generated with a regular HTML form (e.g. has custom headers or a Content-Type that you couldn't use in a form's enctype).

If you are correctly doing something that needs a preflight

In these cases then the rest of this answer still applies but you also need to make sure that the server can listen for the preflight request (which will be OPTIONS (and not GET, POST or whatever you were trying to send) and respond to it with the right Access-Control-Allow-Origin header but also Access-Control-Allow-Methods and Access-Control-Allow-Headers to allow your specific HTTP methods or headers.

If you are triggering a preflight by mistake

Sometimes people make mistakes when trying to construct Ajax requests, and sometimes these trigger the need for a preflight. If the API is designed to allow cross-origin requests, but doesn't require anything that would need a preflight, then this can break access.

Common mistakes that trigger this include:

• trying to put Access-Control-Allow-Origin and other CORS response headers on the request. These don't belong on the request, don't do anything helpful (what would be the point of a permissions system where you could grant yourself permission?), and must appear only on the response.
• trying to put a Content-Type: application/json header on a GET request that has no request body to describe the content of (typically when the author confuses Content-Type and Accept).

In either of these cases, removing the extra request header will often be enough to avoid the need for a preflight (which will solve the problem when communicating with APIs that support simple requests but not preflighted requests).

Opaque responses

Sometimes you need to make an HTTP request, but you don't need to read the response. e.g. if you are posting a log message to the server for recording.

If you are using the fetch API (rather than XMLHttpRequest), then you can configure it to not try to use CORS.

Note that this won't let you do anything that you require CORS to do. You will not be able to read the response. You will not be able to make a request that requires a preflight.

It will let you make a simple request, not see the response, and not fill the Developer Console with error messages.

How to do it is explained by the Chrome error message given when you make a request using fetch and don't get permission to view the response with CORS:

Access to fetch at 'https://example.com/' from origin 'https://example.net' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Thus:

fetch("http://example.com", { mode: "no-cors" });

Alternatives to CORS

JSONP

Bob could also provide the data using a hack like JSONP which is how people did cross-origin Ajax before CORS came along.

It works by presenting the data in the form of a JavaScript program which injects the data into Mallory's page.

It requires that Mallory trust Bob not to provide malicious code.

Note the common theme: The site providing the data has to tell the browser that it is OK for a third party site to access the data it is sending to the browser.

Since JSONP works by appending a <script> element to load the data in the form of a JavaScript program which calls a function already in the page, attempting to use the JSONP technique on a URL which returns JSON will fail — typically with a CORB error — because JSON is not JavaScript.

Move the two resources to a single Origin

If the HTML document the JS runs in and the URL being requested are on the same origin (sharing the same scheme, hostname, and port) then they Same Origin Policy grants permission by default. CORS is not needed.

A Proxy

Mallory could use server-side code to fetch the data (which she could then pass from her server to Alice's browser through HTTP as usual).

It will either:

• add CORS headers
• convert the response to JSONP
• exist on the same origin as the HTML document

That server-side code could be written & hosted by a third party (such as CORS Anywhere). Note the privacy implications of this: The third party can monitor who proxies what across their servers.

Bob wouldn't need to grant any permissions for that to happen.

There are no security implications here since that is just between Mallory and Bob. There is no way for Bob to think that Mallory is Alice and to provide Mallory with data that should be kept confidential between Alice and Bob.

Consequently, Mallory can only use this technique to read public data.

Do note, however, that taking content from someone else's website and displaying it on your own might be a violation of copyright and open you up to legal action.

Writing something other than a web app

As noted in the section "Why the Same Origin Policy only applies to JavaScript in a web page", you can avoid the SOP by not writing JavaScript in a webpage.

That doesn't mean you can't continue to use JavaScript and HTML, but you could distribute it using some other mechanism, such as Node-WebKit or PhoneGap.

Browser extensions

It is possible for a browser extension to inject the CORS headers in the response before the Same Origin Policy is applied.

These can be useful for development, but are not practical for a production site (asking every user of your site to install a browser extension that disables a security feature of their browser is unreasonable).

They also tend to work only with simple requests (failing when handling preflight OPTIONS requests).

Having a proper development environment with a local development server is usually a better approach.

Other security risks

Note that SOP / CORS do not mitigate XSS, CSRF, or SQL Injection attacks which need to be handled independently.

Summary

• There is nothing you can do in your client-side code that will enable CORS access to someone else's server.
• If you control the server the request is being made to: Add CORS permissions to it.
• If you are friendly with the person who controls it: Get them to add CORS permissions to it.
• If it is a public service:
  • Read their API documentation to see what they say about accessing it with client-side JavaScript:
    • They might tell you to use specific URLs
    • They might support JSONP
    • They might not support cross-origin access from client-side code at all (this might be a deliberate decision on security grounds, especially if you have to pass a personalised API Key in each request).
  • Make sure you aren't triggering a preflight request you don't need. The API might grant permission for simple requests but not preflighted requests.
• If none of the above apply: Get the browser to talk to your server instead, and then have your server fetch the data from the other server and pass it on. (There are also third-party hosted services which attach CORS headers to publically accessible resources that you could use).

Try this:

created_at.strftime('%FT%T')

It's a time formatting function which provides you a way to present the string representation of the date. (http://ruby-doc.org/core-2.2.1/Time.html#method-i-strftime).

Same error occurs in localhost, i'm just changing the mysql port (8080 into localhost mysql port 5506). it works for me.

The code project article Creating a Tasktray Application gives a very simple explanation and example of creating an application that only ever exists in the System Tray.

Basically change the Application.Run(new Form1()); line in Program.cs to instead start up a class that inherits from ApplicationContext, and have the constructor for that class initialize a NotifyIcon

static class Program
{
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        Application.Run(new MyCustomApplicationContext());
    }
}


public class MyCustomApplicationContext : ApplicationContext
{
    private NotifyIcon trayIcon;

    public MyCustomApplicationContext ()
    {
        // Initialize Tray Icon
        trayIcon = new NotifyIcon()
        {
            Icon = Resources.AppIcon,
            ContextMenu = new ContextMenu(new MenuItem[] {
                new MenuItem("Exit", Exit)
            }),
            Visible = true
        };
    }

    void Exit(object sender, EventArgs e)
    {
        // Hide tray icon, otherwise it will remain shown until user mouses over it
        trayIcon.Visible = false;

        Application.Exit();
    }
}

I faced an issue in direct download because I was logged in using multiple Google accounts. Solution is append authUser=0 parameter. Sample request URL to download :https://drive.google.com/uc?id=FILEID&authuser=0&export=download

The usual technique for this is margin:auto

However, old IE doesn't grok this so one usually adds text-align: center to an outer containing element. You wouldn't think that would work but the same IE's that ignore auto also incorrectly apply the text align center to block level inner elements so things work out.

And this doesn't actually do a real float.

declare @xx int 
set     @xx = 3 
select @xx      
select @xx * 2  -- yields another integer  
select @xx/1    -- same
select @xx/1.0  --yields 6 decimal places 
select @xx/1.00 --       6 
select @xx * 1.0  --     1 decimal place - victory
select @xx * 1.00 --     2         places - hooray 

Also _ inserting an int into a temp_table with like decimal(10,3) _ works ok.

In development, activating a Spring Boot profile when a specific Maven profile is activate is straight. You should use the profiles property of the spring-boot-maven-plugin in the Maven profile such as :

<project>
    <...>
    <profiles>
        <profile>
            <id>development</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
            <build>
                <plugins>
                    <plugin>
                        <groupId>org.springframework.boot</groupId>
                        <artifactId>spring-boot-maven-plugin</artifactId>
                        <configuration>
                            <profiles>
                                <profile>development</profile>
                            </profiles>
                        </configuration>
                    </plugin>
                </plugins>
            </build>
        </profile>
    <profiles>
    </...>
</project>

You can run the following command to use both the Spring Boot and the Maven development profile :

mvn spring-boot:run -Pdevelopment

If you want to be able to map any Spring Boot profiles to a Maven profile with the same profile name, you could define a single Maven profile and enabling that as the presence of a Maven property is detected. This property would be the single thing that you need to specify as you run the mvn command.
The profile would look like :

    <profile>
        <id>spring-profile-active</id>
        <activation>
            <property>
                <name>my.active.spring.profiles</name>
            </property>
        </activation>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.springframework.boot</groupId>
                    <artifactId>spring-boot-maven-plugin</artifactId>
                    <configuration>
                        <profiles>
                            <profile>${my.active.spring.profiles}</profile>
                        </profiles>
                    </configuration>
                </plugin>
            </plugins>
        </build>
    </profile>

And you can run the following command to use both the Spring Boot and the Maven development profile :

mvn spring-boot:run -Dmy.active.spring.profiles=development

or :

mvn spring-boot:run -Dmy.active.spring.profiles=integration

or :

 mvn spring-boot:run -Dmy.active.spring.profiles=production

And so for...

This kind of configuration makes sense as in the generic Maven profile you rely on the my.active.spring.profiles property that is passed to perform some tasks or value some things.
For example I use this way to configure a generic Maven profile that packages the application and build a docker image specific to the environment selected.

Download MongoDB and install it on your local machine. Link https://www.mongodb.com/try/download/enterprise

Extract the file and put it on the desktop. Create another folder where you want to store the data. I have created mongodb-data folder. Then run the below command.

Desktop/mongodb/bin/mongod --dbpath=/Users/yourname/Desktop/mongodb-data/

Before the hyphen is the executable path of your mongoDB and after hyphen is your data store.

You can rearrange the html, set the container to either flex or grid, and also set for each child the "order" property so it will look as you want

Apparently there is not much out there. And a lot of doubt that someone would be willing to provide such a repository. So I solved the problem myself, and am sharing my dataset with anyone else who finds themselves facing the same problem.

I suggest using the Segment analytics library and following our Angular quickstart guide. You’ll be able to track page visits and track user behavior actions with a single API. If you have an SPA, you can allow the RouterOutlet component to handle when the page renders and use ngOnInit to invoke page calls. The example below shows one way you could do this:

@Component({
  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.css']
})
export class HomeComponent implements OnInit {
  ngOnInit() {
    window.analytics.page('Home');
  }
}

I’m the maintainer of https://github.com/segmentio/analytics-angular. With Segment, you’ll be able to switch different destinations on-and-off by the flip of a switch if you are interested in trying multiple analytics tools (we support over 250+ destinations) without having to write any additional code.

try

var id;
var vname;
function ajaxCall(){
for(var q = 1; q<=10; q++){
 $.ajax({  

 url: 'api.php',                        
 data: 'id1='+q+'',                                                         
 dataType: 'json',
 success: function(data)          
  {

    id = data[0];              
   vname = data[1];
   printWithAjax();
}
      });



}//end of the for statement
  }//end of ajax call function

By using (,), you are capturing the group, if you simply remove them you will not have this problem.

>>> str1 = "a    b     c      d"
>>> re.split(" +", str1)
['a', 'b', 'c', 'd']

However there is no need for regex, str.split without any delimiter specified will split this by whitespace for you. This would be the best way in this case.

>>> str1.split()
['a', 'b', 'c', 'd']

If you really wanted regex you can use this ('\s' represents whitespace and it's clearer):

>>> re.split("\s+", str1)
['a', 'b', 'c', 'd']

or you can find all non-whitespace characters

>>> re.findall(r'\S+',str1)
['a', 'b', 'c', 'd']

Regarding apply vs map:

pool.apply(f, args): f is only executed in ONE of the workers of the pool. So ONE of the processes in the pool will run f(args).

pool.map(f, iterable): This method chops the iterable into a number of chunks which it submits to the process pool as separate tasks. So you take advantage of all the processes in the pool.

You could still use framework 4.0 but you have to include getawaiter for the classes:

MethodName(parameters).ConfigureAwait(false).GetAwaiter().GetResult();

Use the GetType() method

In Android Studio File -> Invalidate Caches/Restart solved the issue for me.

Try this from the command line to change the git config details.

git config --global --replace-all user.name "Your New Name"

git config --global --replace-all user.email "Your new email"

I know the question is about getting the day of week as string (e.g. the short name), but for anybody who is looking for the numeric day of week (as I was), you can use the new "u" format string, supported since Java 7. For example:

new SimpleDateFormat("u").format(new Date());

returns today's day-of-week index, namely: 1 = Monday, 2 = Tuesday, ..., 7 = Sunday.

I'd prefer the built in python html parser, no install no dependencies

soup = BeautifulSoup(s, "html.parser")

Another approach would be like this:

temp = df['Seatblocks'].str.split(' ')
data = data.reindex(data.index.repeat(temp.apply(len)))
data['new_Seatblocks'] = np.hstack(temp)

Inline SVG can be used in IE 10 and 11 and Edge 12.

I've created a project called gray which includes a polyfill for these browsers. The polyfill switches out <img> tags with inline SVG: https://github.com/karlhorky/gray

To implement, the short version is to download the jQuery plugin at the GitHub link above and add after jQuery at the end of your body:

<script src="/js/jquery.gray.min.js"></script>

Then every image with the class grayscale will appear as gray.

<img src="/img/color.jpg" class="grayscale">

You can see a demo too if you like.

This is not dependent on the -- or ++ sign, but it depends on conditions you apply in the loop.

For example: Your loop is faster if the variable has a static value than if your loop check conditions every time, like the length of an array or other conditions.

But don't worry about this optimization, because this time its effect is measured in nanoseconds.

As there is a problem with the third optonal parameter in IE and using closures prevents us from changing the variables (in a loop for example) and still achieving the desired result, I suggest the following solution.

We can try using recursion like this:

var i = 0;
var hellos = ["Hello World1!", "Hello World2!", "Hello World3!", "Hello World4!", "Hello World5!"];

if(hellos.length > 0) timeout();

function timeout() {                
    document.write('<p>' + hellos[i] + '<p>');
    i++;
    if (i < hellos.length)
        setTimeout(timeout, 500);
}

We need to make sure that nothing else changes these variables and that we write a proper recursion condition to avoid infinite recursion.

First you should ask yourself the following question: Do you really need an int?

The purpose of enums is to have a collection of items (constants), that have a meaning in the code without relying on an external value (like an int). Enums in Java can be used as an argument on switch statments and they can safely be compared using "==" equality operator (among others).

Proposal 1 (no int needed) :

Often there is no need for an integer behind it, then simply use this:

private enum DownloadType{
    AUDIO, VIDEO, AUDIO_AND_VIDEO
}

Usage:

DownloadType downloadType = MyObj.getDownloadType();
if (downloadType == DownloadType.AUDIO) {
    //...
}
//or
switch (downloadType) {
  case AUDIO:  //...
          break;
  case VIDEO: //...
          break;
  case AUDIO_AND_VIDEO: //...
          break;
}

Proposal 2 (int needed) :

Nevertheless, sometimes it may be useful to convert an enum to an int (for instance if an external API expects int values). In this case I would advise to mark the methods as conversion methods using the toXxx()-Style. For printing override toString().

private enum DownloadType {
    AUDIO(2), VIDEO(5), AUDIO_AND_VIDEO(11);
    private final int code;

    private DownloadType(int code) {
        this.code = code;
    }

    public int toInt() {
        return code;
    }

    public String toString() {
        //only override toString, if the returned value has a meaning for the
        //human viewing this value 
        return String.valueOf(code);
    }
}

System.out.println(DownloadType.AUDIO.toInt());           //returns 2
System.out.println(DownloadType.AUDIO);                   //returns 2 via `toString/code`
System.out.println(DownloadType.AUDIO.ordinal());         //returns 0
System.out.println(DownloadType.AUDIO.name());            //returns AUDIO
System.out.println(DownloadType.VIDEO.toInt());           //returns 5
System.out.println(DownloadType.VIDEO.ordinal());         //returns 1
System.out.println(DownloadType.AUDIO_AND_VIDEO.toInt()); //returns 11

Summary

• Don't use an Integer together with an enum if you don't have to.
• Don't rely on using ordinal() for getting an integer of an enum, because this value may change, if you change the order (for example by inserting a value). If you are considering to use ordinal() it might be better to use proposal 1.
• Normally don't use int constants instead of enums (like in the accepted answer), because you will loose type-safety.

You model the time function to calculate Fib(n) as sum of time to calculate Fib(n-1) plus the time to calculate Fib(n-2) plus the time to add them together (O(1)). This is assuming that repeated evaluations of the same Fib(n) take the same time - i.e. no memoization is use.

T(n<=1) = O(1)

T(n) = T(n-1) + T(n-2) + O(1)

You solve this recurrence relation (using generating functions, for instance) and you'll end up with the answer.

Alternatively, you can draw the recursion tree, which will have depth n and intuitively figure out that this function is asymptotically O(2n). You can then prove your conjecture by induction.

Base: n = 1 is obvious

Assume T(n-1) = O(2n-1), therefore

T(n) = T(n-1) + T(n-2) + O(1) which is equal to

T(n) = O(2n-1) + O(2n-2) + O(1) = O(2n)

However, as noted in a comment, this is not the tight bound. An interesting fact about this function is that the T(n) is asymptotically the same as the value of Fib(n) since both are defined as

f(n) = f(n-1) + f(n-2).

The leaves of the recursion tree will always return 1. The value of Fib(n) is sum of all values returned by the leaves in the recursion tree which is equal to the count of leaves. Since each leaf will take O(1) to compute, T(n) is equal to Fib(n) x O(1). Consequently, the tight bound for this function is the Fibonacci sequence itself (~?(1.6n)). You can find out this tight bound by using generating functions as I'd mentioned above.

File.OpenText() always uses an UTF-8 StreamReader implicitly. Create your own StreamReader instance instead and specify the desired encoding. like

using (StreamReader reader =  new StreamReader(@"C:\test.txt", Encoding.Default)
 {
 // ...
 }

From my test (spring 3.0.5), @RequestMapping(value={"", "/"}) - only "/" works, "" does not. However I found out this works: @RequestMapping(value={"/", " * "}), the " * " matches anything, so it will be the default handler in case no others.

The includes (formerly called contains and include) method compares objects by reference (or more precisely, with ===). Because the two object literals of {"b": 2} in your example represent different instances, they are not equal. Notice:

({"b": 2} === {"b": 2})
> false

However, this will work because there is only one instance of {"b": 2}:

var a = {"a": 1}, b = {"b": 2};
_.includes([a, b], b);
> true

On the other hand, the where(deprecated in v4) and find methods compare objects by their properties, so they don't require reference equality. As an alternative to includes, you might want to try some (also aliased as any):

_.some([{"a": 1}, {"b": 2}], {"b": 2})
> true

CountRows = ThisWorkbook.Worksheets(1).Range("A:A").Cells.SpecialCells(xlCellTypeConstants).Count

The explanation below from the official documentation helped me understand kubectl apply.

This command will compare the version of the configuration that you’re pushing with the previous version and apply the changes you’ve made, without overwriting any automated changes to properties you haven’t specified.

kubectl create on the other hand will create (should be non-existing) resources.

This can happen if disableContentCompression() is set on a pooling manager assigned to your HttpClient, and the target server is trying to use gzip compression.

I searched for this very question and when I saw the answers I ended up creating something different (because I favor less code over most other things most of the time) that should work in the vast majority of cases. Basically turn the array into a string with array elements separated by some delimiter character, and then wrap the search value in the delimiter character and pass through instr.

Function is_in_array(value As String, test_array) As Boolean
    If Not (IsArray(test_array)) Then Exit Function
    If InStr(1, "'" & Join(test_array, "'") & "'", "'" & value & "'") > 0 _
        Then is_in_array = True
End Function

And you'd execute the function like this:

test = is_in_array(1, array(1, 2, 3))

Move semantics allows for a straightforward way to release memory, by simply applying the assignment (=) operator from an empty rvalue:

std::vector<uint32_t> vec(100, 0);
std::cout << vec.capacity(); // 100

vec = vector<uint32_t>();    // Same as "vector<uint32_t>().swap(vec)";    
std::cout << vec.capacity(); // 0

It is as much efficient as the "swap()"-based method described in other answers (indeed, both are conceptually doing the same thing). When it comes to readability, however, the assignment version makes a better job at expressing the programmer's intention while being more concise.

You can define your title programatically using setTitle within your Activity, this method can accept either a String or an ID defined in your values/strings.xml file. Example:

public class YourActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {

        setTitle(R.string.your_title);
        setContentView(R.layout.main);

    }
}

If you want to use Apple’s system install of Python 2.7, be aware that it doesn’t quite follow the naming standards laid out in PEP 394.

In particular, it includes the optional symlinks with suffix 2.7 that you’re told not to rely on, and does not include the recommended symlinks with suffix 2 that you’re told you should rely on.

If you want to fix this, while sticking with Apple’s Python, you can create your own symlinks:

$ cd <somewhere writable and in your PATH>
$ ln -s /usr/bin/python python2

Or aliases in your bash config:

alias python2 python2.7

And you can do likewise for Apple’s 2to3, easy_install, etc. if you need them.

You shouldn’t try to put these symlinks into /usr/bin, and definitely don’t try to rename what’s already there, or to change the distutils setup to something more PEP-compliant. Those files are all part of the OS, and can be used by other parts of the OS, and your changes can be overwritten on even a minor update from 10.13.5 to 10.13.6 or something, so leave them alone and work around them as described above.

Alternatively, you could:

• Just use python2.7 instead of python2 on the command line and in your shbangs and so on.
• Use virtual environments or conda environments. The global python, python3, python2, etc. don’t matter when you’re always using the activated environment’s local python.
• Stop using Apple’s 2.7 and instead install a whole other 2.7 alongside it, as most of the other answers suggest. (I don’t know why so many of them are also suggesting that you install a second 3.6. That’s just going to add even more confusion, for no benefit.)

I had to enable it in my BIOS as shown below (for Asus):

Thanks, Thomas. I'm new to JS and I've been looking crazy for a solution to my problem. Yours helped.

I've used jquery to make a Login-box that slides down. For best user experience I desided to make the box disappear when user clicks somewhere but the box. I'm a little bit embarrassed over using about four hours fixing this. But hey, I'm new to JS.

Maybe my code can help someone out:

<body>
<button class="login">Logg inn</button>
<script type="text/javascript">

    $("button.login").click(function () {
        if ($("div#box:first").is(":hidden")) {
                $("div#box").slideDown("slow");} 
            else {
                $("div#box").slideUp("slow");
                }
    });
    </script>
<div id="box">Lots of login content</div>

<script type="text/javascript">
    var box = $('#box');
    var login = $('.login');

    login.click(function() {
        box.show(); return false;
    });

    $(document).click(function() {
        box.hide();
    });

    box.click(function(e) {
        e.stopPropagation();
    });

</script>

</body>

I think Sanjay's answer was almost there but i used it this way

NSArray *myArray = [[NSArray alloc] initWithObjects:@"Hello",@"World", nil];
NSString *greeting = [myArray componentsJoinedByString:@" "];
NSLog(@"%@",greeting);

Output :

2015-01-25 08:47:14.830 StringTest[11639:394302] Hello World

As Sanjay had hinted - I used method componentsJoinedByString from NSArray that does joining and gives you back NSString

BTW NSString has reverse method componentsSeparatedByString that does the splitting and gives you NSArray back .

Documentation for parseDouble() says "Returns a new double initialized to the value represented by the specified String, as performed by the valueOf method of class Double.", so they should be identical.

You have it backwards. Display the calendar first, and then call gotoDate.

$('#calendar').fullCalendar({
  // Options
});

$('#calendar').fullCalendar('gotoDate', currentDate);

You need to use ng-disabled directive

<input data-ng-model="userInf.username" 
       class="span12 editEmail" 
       type="text" 
       placeholder="[email protected]" 
       pattern="[^@]+@[^@]+\.[a-zA-Z]{2,6}" 
       required 
       ng-disabled="<expression to disable>" />

Better one is here.

$('#submit').click(function()
{
    if( !$('#myMessage').val() ) {
       alert('warning');
    }
});

And you don't necessarily need .length or see if its >0 since an empty string evaluates to false anyway but if you'd like to for readability purposes:

$('#submit').on('click',function()
{
    if( $('#myMessage').val().length === 0 ) {
        alert('warning');
    }
});

If you're sure it will always operate on a textfield element then you can just use this.value.

$('#submit').click(function()
{
      if( !document.getElementById('myMessage').value ) {
          alert('warning');
      }
});

Also you should take note that $('input:text') grabs multiple elements, specify a context or use the this keyword if you just want a reference to a lone element ( provided theres one textfield in the context's descendants/children ).

It's only dropping the fractional part after decimal. Have you tried : 4.0 / 100

For more generic advice on debugging this kind of problem MDN have a good article TypeError: "x" is not a function:

It was attempted to call a value like a function, but the value is not actually a function. Some code expects you to provide a function, but that didn't happen.

Maybe there is a typo in the function name? Maybe the object you are calling the method on does not have this function? For example, JavaScript objects have no map function, but JavaScript Array object do.

Basically the object (all functions in js are also objects) does not exist where you think it does. This could be for numerous reasons including(not an extensive list):

• Missing script library
• Typo
• The function is within a scope that you currently do not have access to, e.g.:

var x = function(){_x000D_
   var y = function() {_x000D_
      alert('fired y');_x000D_
   }_x000D_
};_x000D_
    _x000D_
//the global scope can't access y because it is closed over in x and not exposed_x000D_
//y is not a function err triggered_x000D_
x.y();

• Your object/function does not have the function your calling:

var x = function(){_x000D_
   var y = function() {_x000D_
      alert('fired y');_x000D_
   }_x000D_
};_x000D_
    _x000D_
//z is not a function error (as above) triggered_x000D_
x.z();

Quote from the Spring reference doc:

Upon initialization of a DispatcherServlet, Spring MVC looks for a file named [servlet-name]-servlet.xml in the WEB-INF directory of your web application and creates the beans defined there...

Your servlet is called spring-dispatcher, so it looks for /WEB-INF/spring-dispatcher-servlet.xml. You need to have this servlet configuration, and define web related beans in there (like controllers, view resolvers, etc). See the linked documentation for clarification on the relation of servlet contexts to the global application context (which is the app-config.xml in your case).

One more thing, if you don't like the naming convention of the servlet config xml, you can specify your config explicitly:

<servlet>
    <servlet-name>spring-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

This is my generic solution for any string s and any index i:

def remove_at(i, s):
    return s[:i] + s[i+1:]

There is a contains method for lists, so you should be able to do:

Arrays.asList(yourArray).contains(yourObject);

Warning: this might not do what you (or I) expect, see Tom's comment below.

If none of above stated works then check for your device date, make sure your device date doesn't exceed profile expiry date i.e. not set to far future.

You can get the screen size with the Toolkit.getScreenSize() method.

Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
double width = screenSize.getWidth();
double height = screenSize.getHeight();

On a multi-monitor configuration you should use this :

GraphicsDevice gd = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
int width = gd.getDisplayMode().getWidth();
int height = gd.getDisplayMode().getHeight();

If you want to get the screen resolution in DPI you'll have to use the getScreenResolution() method on Toolkit.

• javadoc - Toolkit.getScreenSize()
• Java bug 5100801- Toolkit.getScreenSize() does not return the correct dimension on multimon, linux

You should absolutely avoid using IsNothing()

Here are 4 reasons from the article IsNothing() VS Is Nothing

1. Most importantly, IsNothing(object) has everything passed to it as an object, even value types! Since value types cannot be Nothing, it’s a completely wasted check.
   Take the following example:

   Dim i As Integer
   If IsNothing(i) Then
      ' Do something 
   End If
   

   This will compile and run fine, whereas this:

   Dim i As Integer
   If i Is Nothing Then
       '   Do something 
   End If
   

   Will not compile, instead the compiler will raise the error:

   'Is' operator does not accept operands of type 'Integer'.
   Operands must be reference or nullable types.

2. IsNothing(object) is actually part of part of the Microsoft.VisualBasic.dll.
   This is undesirable as you have an unneeded dependency on the VisualBasic library.

3. Its slow - 33.76% slower in fact (over 1000000000 iterations)!

4. Perhaps personal preference, but IsNothing() reads like a Yoda Condition. When you look at a variable you're checking it's state, with it as the subject of your investigation.

   i.e. does it do x? --- NOT Is xing a property of it?

   So I think If a IsNot Nothing reads better than If Not IsNothing(a)

According to pip documentation at

http://pip.readthedocs.org/en/stable/user_guide/#configuration

You will need to specify the default install location within a pip.ini file, which, also according to the website above is usually located as follows

On Unix and Mac OS X the configuration file is: $HOME/.pip/pip.conf

On Windows, the configuration file is: %HOME%\pip\pip.ini

The %HOME% is located in C:\Users\Bob on windows assuming your name is Bob

On linux the $HOME directory can be located by using cd ~

You may have to create the pip.ini file when you find your pip directory. Within your pip.ini or pip.config you will then need to put (assuming your on windows) something like

[global]
target=C:\Users\Bob\Desktop

Except that you would replace C:\Users\Bob\Desktop with whatever path you desire. If you are on Linux you would replace it with something like /usr/local/your/path

After saving the command would then be

pip install pandas

However, the program you install might assume it will be installed in a certain directory and might not work as a result of being installed elsewhere.

Alternatively, I recommend installing Homebrew for these kinds of utilities.

Then you just install Maven using:

brew install maven

PS: If you got a 404 error, try doing a brew update just before

422 Unprocessable Entity Explained Updated: March 6, 2017

What Is 422 Unprocessable Entity?

A 422 status code occurs when a request is well-formed, however, due to semantic errors it is unable to be processed. This HTTP status was introduced in RFC 4918 and is more specifically geared toward HTTP extensions for Web Distributed Authoring and Versioning (WebDAV).

There is some controversy out there on whether or not developers should return a 400 vs 422 error to clients (more on the differences between both statuses below). However, in most cases, it is agreed upon that the 422 status should only be returned if you support WebDAV capabilities.

A word-for-word definition of the 422 status code taken from section 11.2 in RFC 4918 can be read below.

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415(Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions.

The definition goes on to say:

For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

400 vs 422 Status Codes

Bad request errors make use of the 400 status code and should be returned to the client if the request syntax is malformed, contains invalid request message framing, or has deceptive request routing. This status code may seem pretty similar to the 422 unprocessable entity status, however, one small piece of information that distinguishes them is the fact that the syntax of a request entity for a 422 error is correct whereas the syntax of a request that generates a 400 error is incorrect.

The use of the 422 status should be reserved only for very particular use-cases. In most other cases where a client error has occurred due to malformed syntax, the 400 Bad Request status should be used.

If you are using jQuery.. then I can suggest the following: NOTE: I made some assumption here

$('#my_checkbox').click(function(){
    if($(this).is(':checked')){
        $('input[name="totalCost"]').val(10);
    } else {
        calculate();
    }
});

From http://www.cplusplus.com/reference/string/stoi/

// stoi example
#include <iostream>   // std::cout
#include <string>     // std::string, std::stoi

int main ()
{
  std::string str_dec = "2001, A Space Odyssey";
  std::string str_hex = "40c3";
  std::string str_bin = "-10010110001";
  std::string str_auto = "0x7f";

  std::string::size_type sz;   // alias of size_t

  int i_dec = std::stoi (str_dec,&sz);
  int i_hex = std::stoi (str_hex,nullptr,16);
  int i_bin = std::stoi (str_bin,nullptr,2);
  int i_auto = std::stoi (str_auto,nullptr,0);

  std::cout << str_dec << ": " << i_dec << " and [" << str_dec.substr(sz) << "]\n";
  std::cout << str_hex << ": " << i_hex << '\n';
  std::cout << str_bin << ": " << i_bin << '\n';
  std::cout << str_auto << ": " << i_auto << '\n';

  return 0;
}

Output:

2001, A Space Odyssey: 2001 and [, A Space Odyssey]

40c3: 16579

-10010110001: -1201

0x7f: 127

If it is a directory you own, grant yourself access to it:

chmod u+rx,go-w openfire

That grants you permission to use the directory and the files in it (x) and to list the files that are in it (r); it also denies group and others write permission on the directory, which is usually correct (though sometimes you may want to allow group to create files in your directory - but consider using the sticky bit on the directory if you do).

If it is someone else's directory, you'll probably need some help from the owner to change the permissions so that you can access it (or you'll need help from root to change the permissions for you).

You cannot use both -jar and -cp on the command line - see the java documentation that says that if you use -jar:

the JAR file is the source of all user classes, and other user class path settings are ignored.

You could do something like this:

java -cp lib\*.jar;. myproject.MainClass

Notice the ;. in the -cp argument, to work around a Java command-line bug. Also, please note that this is the Windows version of the command. The path separator on Unix is :.

Well, here is my "answer". It uses the fact that String.Split can be told hold many items it should split to (which I found lacking in the other answers):

string theString = "Some Very Large String Here";
var array = theString.Split(new [] { ' ' }, 2); // return at most 2 parts
// note: be sure to check it's not an empty array
string firstElem = array[0];
// note: be sure to check length first
string restOfArray = array[1];

This is very similar to the Substring method, just by a different means.

In Excel, the substring function is called MID function, and indexOf is called FIND for case-sensitive location and SEARCH function for non-case-sensitive location. For the first portion of your text parsing the LEFT function may also be useful.

See all the text functions here: Text Functions (reference).

Look at the following:

map(multilambda x:
      y=x+1
      return y
   , [1,2,3])

Is this a lambda returning (y, [1,2,3]) (thus map only gets one parameter, resulting in an error)? Or does it return y? Or is it a syntax error, because the comma on the new line is misplaced? How would Python know what you want?

Within the parens, indentation doesn't matter to python, so you can't unambiguously work with multilines.

This is just a simple one, there's probably more examples.

The simplest way to do this is like this

index.php

<?php $active = 'home'; include 'second.php'; ?>

second.php

<?php echo $active; ?>

You can share variables since you are including 2 files by using "include"

Put 0 as default in SQL or add 0 into your area of table

Use the "geometry" package and write \newgeometry{left=3cm,bottom=0.1cm} where you want to change your margins. When you want to reset your margins, you write \restoregeometry.

extension UIColor {
    public convenience init?(hex: String) {
        let r, g, b, a: CGFloat

        if hex.hasPrefix("#") {
            let start = hex.index(hex.startIndex, offsetBy: 1)
            let hexColor = String(hex[start...])

            if hexColor.count == 8 {
                let scanner = Scanner(string: hexColor)
                var hexNumber: UInt64 = 0

                if scanner.scanHexInt64(&hexNumber) {
                    r = CGFloat((hexNumber & 0xff000000) >> 24) / 255
                    g = CGFloat((hexNumber & 0x00ff0000) >> 16) / 255
                    b = CGFloat((hexNumber & 0x0000ff00) >> 8) / 255
                    a = CGFloat(hexNumber & 0x000000ff) / 255

                    self.init(red: r, green: g, blue: b, alpha: a)
                    return
                }
            }
        }

        return nil
    }
}

Usage:

let white = UIColor(hex: "#ffffff")

You have to implement getItemViewType() method in RecyclerView.Adapter. By default onCreateViewHolder(ViewGroup parent, int viewType) implementation viewType of this method returns 0. Firstly you need view type of the item at position for the purposes of view recycling and for that you have to override getItemViewType() method in which you can pass viewType which will return your position of item. Code sample is given below

@Override
public MyViewholder onCreateViewHolder(ViewGroup parent, int viewType) {
    int listViewItemType = getItemViewType(viewType);
    switch (listViewItemType) {
         case 0: return new ViewHolder0(...);
         case 2: return new ViewHolder2(...);
    }
}

@Override
public int getItemViewType(int position) {   
    return position;
}

// and in the similar way you can set data according 
// to view holder position by passing position in getItemViewType
@Override
public void onBindViewHolder(MyViewholder viewholder, int position) {
    int listViewItemType = getItemViewType(position);
    // ...
}

You can do this by calling the constructor each time with is slightly better

var tupleList = new List<Tuple<int, string>>
{
    new Tuple<int, string>(1, "cow" ),
    new Tuple<int, string>( 5, "chickens" ),
    new Tuple<int, string>( 1, "airplane" )
};

Easiest way

$('#yourform *').prop('readonly', true);

according to http://mylinuxbook.com/hexdump/ you might use the hexdump format parameter

echo Aa | hexdump -C -e '/1 "%02X"'

will return 4161

to add an extra linefeed at the end, append another formatter.

BUT: the format given above will give multiplier outputs for repetitive characters

$ printf "Hello" | hexdump -e '/1 "%02X"' 
48656C*
6F

instead of

48656c6c6f

You can use Ternary operator logic Ternary operator logic is the process of using "(condition)? (true return value) : (false return value)" statements to shorten your if/else structures. i.e

/* most basic usage */
$var = 5;
$var_is_greater_than_two = ($var > 2 ? true : false); // returns true

You can use a function like this. Complete and modify it to your need :

/**
     * Encode URL (except :, /, ?, &, =, ... characters)
     * @param url to encode
     * @param encodingCharset url encoding charset
     * @return encoded URL
     * @throws UnsupportedEncodingException
     */
    public static String encodeUrl (String url, String encodingCharset) throws UnsupportedEncodingException{
            return new URLCodec().encode(url, encodingCharset).replace("%3A", ":").replace("%2F", "/").replace("%3F", "?").replace("%3D", "=").replace("%26", "&");
    }

Example of use :

String urlToEncode = ""http://www.growup.com/folder/intérieur-à_vendre?o=4";
Utils.encodeUrl (urlToEncode , "UTF-8")

The result is : http://www.growup.com/folder/int%C3%A9rieur-%C3%A0_vendre?o=4

I use this one:

LocationManager.requestLocationUpdates(String provider, long minTime, float minDistance, LocationListener listener)

For example, using a 1s interval:

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,this);

the time is in milliseconds, the distance is in meters.

This automatically calls:

public void onLocationChanged(Location location) {
    //Code here, location.getAccuracy(), location.getLongitude() etc...
}

I also had these included in the script but didnt actually use them:

public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}

In short:

public class GPSClass implements LocationListener {

    public void onLocationChanged(Location location) {
        // Called when a new location is found by the network location provider.
        Log.i("Message: ","Location changed, " + location.getAccuracy() + " , " + location.getLatitude()+ "," + location.getLongitude());
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {}
    public void onProviderEnabled(String provider) {}
    public void onProviderDisabled(String provider) {}

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,this);
    }
}

The problem is that the small figure region 2 created by your layout() call is not sufficiently large enough to contain just the default margins, let alone a plot.

More generally, you get this error if the size of the plotting region on the device is not large enough to actually do any plotting. For the OP's case the issue was having too small a plotting device to contain all the subplots and their margins and leave a large enough plotting region to draw in.

RStudio users can encounter this error if the Plot tab is too small to leave enough room to contain the margins, plotting region etc. This is because the physical size of that pane is the size of the graphics device. These are not independent issues; the plot pane in RStudio is just another plotting device, like png(), pdf(), windows(), and X11().

Solutions include:

1. reducing the size of the margins; this might help especially if you are trying, as in the case of the OP, to draw several plots on the same device.

2. increasing the physical dimensions of the device, either in the call to the device (e.g. png(), pdf(), etc) or by resizing the window / pane containing the device

3. reducing the size of text on the plot as that can control the size of margins etc.

Reduce the size of the margins

Before the line causing the problem try:

par(mar = rep(2, 4))

then plot the second image

image(as.matrix(leg),col=cx,axes=T)

You'll need to play around with the size of the margins on the par() call I show to get this right.

Increase the size of the device

You may also need to increase the size of the actual device onto which you are plotting.

A final tip, save the par() defaults before changing them, so change your existing par() call to:

op <- par(oma=c(5,7,1,1))

then at the end of plotting do

par(op)

If you use the new class dialog in Eclipse you can just set the Superclass field to java.lang.Exception and check "Constructors from superclass" and it will generate the following:

package com.example.exception;

public class MyException extends Exception {

    public MyException() {
        // TODO Auto-generated constructor stub
    }

    public MyException(String message) {
        super(message);
        // TODO Auto-generated constructor stub
    }

    public MyException(Throwable cause) {
        super(cause);
        // TODO Auto-generated constructor stub
    }

    public MyException(String message, Throwable cause) {
        super(message, cause);
        // TODO Auto-generated constructor stub
    }

}

In response to the question below about not calling super() in the defualt constructor, Oracle has this to say:

Note: If a constructor does not explicitly invoke a superclass constructor, the Java compiler automatically inserts a call to the no-argument constructor of the superclass.

No, VB.NET does not yet have such a feature. It will be available in the next iteration of VB (visual basic 10) however (link)

select distinct title, (
               select count(title) 
               from kmovies as sub 
               where sub.title=kmovies.title) as cnt 
from kmovies 
group by title 
order by cnt desc

You can't add an icon and text because you can't apply a different font to part of a placeholder, however, if you are satisfied with just an icon then it can work. The FontAwesome icons are just characters with a custom font (you can look at the FontAwesome Cheatsheet for the escaped Unicode character in the content rule. In the less source code it's found in variables.less The challenge would be to swap the fonts when the input is not empty. Combine it with jQuery like this.

<form role="form">
  <div class="form-group">
    <input type="text" class="form-control empty" id="iconified" placeholder="&#xF002;"/>
  </div>
</form>

With this CSS:

input.empty {
    font-family: FontAwesome;
    font-style: normal;
    font-weight: normal;
    text-decoration: inherit;
}

And this (simple) jQuery

$('#iconified').on('keyup', function() {
    var input = $(this);
    if(input.val().length === 0) {
        input.addClass('empty');
    } else {
        input.removeClass('empty');
    }
});

The transition between fonts will not be smooth, however.

\d is a digit, + is 1 or more, so a sequence of 1 or more digits

I don't think there would be any significant performance difference between them, but I would prefer the 1st way.

If you have a Boolean reference, Boolean.toString(boolean) will throw NullPointerException if your reference is null. As the reference is unboxed to boolean before being passed to the method.

While, String.valueOf() method as the source code shows, does the explicit null check:

public static String valueOf(Object obj) {
    return (obj == null) ? "null" : obj.toString();
}

Just test this code:

Boolean b = null;

System.out.println(String.valueOf(b));    // Prints null
System.out.println(Boolean.toString(b));  // Throws NPE

For primitive boolean, there is no difference.

DataSet ds = new DataSet();
ds.ReadXml(fileNamePath);

Further to the other answers suggesting LINQ, another alternative in this case would be to use the FindAll instance method:

List<SampleClass> results = myList.FindAll(x => x.Name == nameToExtract);

The basic way is:

printf ("Here are the first 8 chars: %.8s\n", "A string that is more than 8 chars");

The other, often more useful, way is:

printf ("Here are the first %d chars: %.*s\n", 8, 8, "A string that is more than 8 chars");

Here, you specify the length as an int argument to printf(), which treats the '*' in the format as a request to get the length from an argument.

You can also use the notation:

printf ("Here are the first 8 chars: %*.*s\n",
        8, 8, "A string that is more than 8 chars");

This is also analogous to the "%8.8s" notation, but again allows you to specify the minimum and maximum lengths at runtime - more realistically in a scenario like:

printf("Data: %*.*s Other info: %d\n", minlen, maxlen, string, info);

The POSIX specification for printf() defines these mechanisms.

This will return a list of 10 numbers selected from the range 0 to 99, without duplicates.

import random
random.sample(range(100), 10)

With reference to your specific code example, you probably want to read all the lines from the file once and then select random lines from the saved list in memory. For example:

all_lines = f1.readlines()
for i in range(50):
    lines = random.sample(all_lines, 40)

This way, you only need to actually read from the file once, before your loop. It's much more efficient to do this than to seek back to the start of the file and call f1.readlines() again for each loop iteration.

I'd personally make use of the table.insert function:

table.insert(a,"b");

This saves you from having to iterate over the whole table therefore saving valuable resources such as memory and time.

Note that SimpleDateFormat format pattern Z is for RFC 822 time zone and pattern X is for ISO 8601 (this standard supports single letter time zone names like Z for Zulu).

So new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSX") produces a format that can parse both "2013-03-11T01:38:18.309Z" and "2013-03-11T01:38:18.309+0000" and will give you the same result.

Unfortunately, as far as I can tell, you can't get this format to generate the Z for Zulu version, which is annoying.

I actually have more trouble on the JavaScript side to deal with both formats.

There is a built in function to compare lists:

Following is the syntax for cmp() method -

cmp(list1, list2)

#!/usr/bin/python

list1, list2 = [123, 'xyz'], [123, 'xyz']

print cmp(list1,list2)

When we run above program, it produces following result -

0

If the result is a tie, meaning that 0 is returned

Talking is more than simply exchanging information. A Protocol is actually designed so that no talking has to occur. Each party knows what their particular job is because it is specified in the protocol. Protocols allow for pure information exchange at the expense of having any changes in the possible actions. Talking, on the other hand, allows for one party to ask what further actions can be taken from the other party. They can even ask the same question twice and get two different answers, since the State of the other party may have changed in the interim. Talking is RESTful architecture. Fielding's thesis specifies the architecture that one would have to follow if one wanted to allow machines to talk to one another rather than simply communicate.

Available fonts (as of Oreo)

The Material Design Typography page has demos for some of these fonts and suggestions on choosing fonts and styles.

For code sleuths: fonts.xml is the definitive and ever-expanding list of Android fonts.

Using these fonts

Set the android:fontFamily and android:textStyle attributes, e.g.

<!-- Roboto Bold -->
<TextView
    android:fontFamily="sans-serif"
    android:textStyle="bold" />

to the desired values from this table:

Font                     | android:fontFamily          | android:textStyle
-------------------------|-----------------------------|-------------------
Roboto Thin              | sans-serif-thin             |
Roboto Light             | sans-serif-light            |
Roboto Regular           | sans-serif                  |
Roboto Bold              | sans-serif                  | bold
Roboto Medium            | sans-serif-medium           |
Roboto Black             | sans-serif-black            |
Roboto Condensed Light   | sans-serif-condensed-light  |
Roboto Condensed Regular | sans-serif-condensed        |
Roboto Condensed Medium  | sans-serif-condensed-medium |
Roboto Condensed Bold    | sans-serif-condensed        | bold
Noto Serif               | serif                       |
Noto Serif Bold          | serif                       | bold
Droid Sans Mono          | monospace                   |
Cutive Mono              | serif-monospace             |
Coming Soon              | casual                      |
Dancing Script           | cursive                     |
Dancing Script Bold      | cursive                     | bold
Carrois Gothic SC        | sans-serif-smallcaps        |

(Noto Sans is a fallback font; you can't specify it directly)

Note: this table is derived from fonts.xml. Each font's family name and style is listed in fonts.xml, e.g.

<family name="serif-monospace">
    <font weight="400" style="normal">CutiveMono.ttf</font>
</family>

serif-monospace is thus the font family, and normal is the style.

Compatibility

Based on the log of fonts.xml and the former system_fonts.xml, you can see when each font was added:

• Ice Cream Sandwich: Roboto regular, bold, italic, and bold italic
• Jelly Bean: Roboto light, light italic, condensed, condensed bold, condensed italic, and condensed bold italic
• Jelly Bean MR1: Roboto thin and thin italic
• Lollipop:
  • Roboto medium, medium italic, black, and black italic
  • Noto Serif regular, bold, italic, bold italic
  • Cutive Mono
  • Coming Soon
  • Dancing Script
  • Carrois Gothic SC
  • Noto Sans
• Oreo MR1: Roboto condensed medium

First off, rmaddy's answer (above) is right: implementing NSCoding doesn't help. However, you need to implement NSCoding to use NSKeyedArchiver and all that, so it's just one more step... converting via NSData.

Example methods

- (NSUserDefaults *) defaults {
    return [NSUserDefaults standardUserDefaults];
}

- (void) persistObj:(id)value forKey:(NSString *)key {
    [self.defaults setObject:value  forKey:key];
    [self.defaults synchronize];
}

- (void) persistObjAsData:(id)encodableObject forKey:(NSString *)key {
    NSData *data = [NSKeyedArchiver archivedDataWithRootObject:encodableObject];
    [self persistObj:data forKey:key];
}    

- (id) objectFromDataWithKey:(NSString*)key {
    NSData *data = [self.defaults objectForKey:key];
    return [NSKeyedUnarchiver unarchiveObjectWithData:data];
}

So you can wrap your NSCoding objects in an NSArray or NSDictionary or whatever...

HTML:

<body ng-app="App">
    <div ng-controller="testController" >
        <input type="hidden" id="testInput" ng-model="testInput" ng-init="testInput=123" />
    </div>
    {{ testInput }}
</body>

JS:

angular.module('App', []);

testController = function ($scope) {
    console.log('test');
    $scope.$watch('testInput', testShow, true);
    function testShow() {
      console.log($scope.testInput);
    }
}

Fiddle

interface IBox {
    x: number;
    y: number;
    height: number;
    width: number;
}

class Box {
    public x: number;
    public y: number;
    public height: number;
    public width: number;

    constructor(obj: IBox) {
        const { x, y, height, width } = { x: 0, y: 0, height: 0, width: 0, ...obj }
        this.x = x;
        this.y = y;
        this.height = height;
        this.width = width;
    }
}

If you don't have cocoa pods installed you need to:

sudo gem install cocoapods

Then run:

cd /ios
pod install

delete the build folder in ios folder of your react native project

run:

react-native run-ios

if error persists:

• delete build folder again
• open the /ios folder in Xcode
• navigate File -> Project Settings -> Build System -> change (Shared workspace settings and Per-User workspace settings): Build System -> Legacy Build System

A roll your own function.

Supports recursion or not with the 2nd switch.

Also, allow names of files with ; which the accepted answer fails to address although a great answer, this will get over that issue.

The idea was taken from https://ss64.com/nt/empty.html

    set msg=!count!
    )
   )
  )
  set "%~1=!msg!" & goto :eof
  )

Just put the condition into the lambda itself, e.g.

animalMap.entrySet().stream()
        .forEach(
                pair -> {
                    if (pair.getValue() != null) {
                        myMap.put(pair.getKey(), pair.getValue());
                    } else {
                        myList.add(pair.getKey());
                    }
                }
        );

Of course, this assumes that both collections (myMap and myList) are declared and initialized prior to the above piece of code.

Update: using Map.forEach makes the code shorter, plus more efficient and readable, as Jorn Vernee kindly suggested:

    animalMap.forEach(
            (key, value) -> {
                if (value != null) {
                    myMap.put(key, value);
                } else {
                    myList.add(key);
                }
            }
    );

rails s -e production

This will run the server with RAILS_ENV = 'production'.

Apart from this you have to set the assets path in production.rb

config.serve_static_assets = true

Without this your assets will not be loaded.

You're missing __init__.py. From the Python tutorial:

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path. In the simplest case, __init__.py can just be an empty file, but it can also execute initialization code for the package or set the __all__ variable, described later.

Put an empty file named __init__.py in your Models directory, and all should be golden.

You missed the each= argument to rep():

R> n <- 3
R> rep(1:5, each=n)
 [1] 1 1 1 2 2 2 3 3 3 4 4 4 5 5 5
R> 

so your example can be done with a simple

R> rep(1:8, each=20)

There's also a DailyRollingFileAppender

Edit: after reading this worrying statement:

DailyRollingFileAppender has been observed to exhibit synchronization issues and data loss. The log4j extras companion includes alternatives which should be considered for new deployments and which are discussed in the documentation for org.apache.log4j.rolling.RollingFileAppender.

from the above URL (which I never realized before), then the log4j-extras looks to be a better option.

You are missing either the inclusion of the route package, or including the router module in your main app module.

Make sure your package.json has this:

"@angular/router": "^3.3.1"

Then in your app.module import the router and configure the routes:

import { RouterModule } from '@angular/router';

imports: [
        RouterModule.forRoot([
            {path: '', component: DashboardComponent},
            {path: 'dashboard', component: DashboardComponent}
        ])
    ],

Update:

Move the AppRoutingModule to be first in the imports:

imports: [
    AppRoutingModule.
    BrowserModule,
    FormsModule,
    HttpModule,
    AlertModule.forRoot(), // What is this?
    LayoutModule,
    UsersModule
  ],

I found this because my EditText wasn't automatically getting dismissed on enter.

This was my original code.

editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if ( (actionId == EditorInfo.IME_ACTION_DONE) || ((event.getKeyCode() == KeyEvent.KEYCODE_ENTER) && (event.getAction() == KeyEvent.ACTION_DOWN ))) {

            // Do stuff when user presses enter

            return true;

        }

        return false;
    }
});

I solved it by removing the line

return true;

after doing stuff when user presses enter.

Hope this helps someone.

I'd advise against mix-ins in new Python code, if you can find any other way around it (such as composition-instead-of-inheritance, or just monkey-patching methods into your own classes) that isn't much more effort.

In old-style classes you could use mix-ins as a way of grabbing a few methods from another class. But in the new-style world everything, even the mix-in, inherits from object. That means that any use of multiple inheritance naturally introduces MRO issues.

There are ways to make multiple-inheritance MRO work in Python, most notably the super() function, but it means you have to do your whole class hierarchy using super(), and it's considerably more difficult to understand the flow of control.

Works properly on Andorid 8.1:

Updated sample (without any deprecated code):

public NotificationBattery(Context context) {
    this.mCtx = context;

    mBuilder = new NotificationCompat.Builder(context, CHANNEL_ID)
            .setContentTitle(context.getString(R.string.notification_title_battery))
            .setSmallIcon(R.drawable.ic_launcher)
            .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
            .setChannelId(CHANNEL_ID)
            .setOnlyAlertOnce(true)
            .setPriority(NotificationCompat.PRIORITY_MAX)
            .setWhen(System.currentTimeMillis() + 500)
            .setGroup(GROUP)
            .setOngoing(true);

    mRemoteViews = new RemoteViews(context.getPackageName(), R.layout.notification_view_battery);

    initBatteryNotificationIntent();

    mBuilder.setContent(mRemoteViews);

    mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

    if (AesPrefs.getBooleanRes(R.string.SHOW_BATTERY_NOTIFICATION, true)) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel channel = new NotificationChannel(CHANNEL_ID, context.getString(R.string.notification_title_battery),
                    NotificationManager.IMPORTANCE_DEFAULT);
            channel.setShowBadge(false);
            channel.setSound(null, null);
            mNotificationManager.createNotificationChannel(channel);
        }
    } else {
        mNotificationManager.cancel(Const.NOTIFICATION_CLIPBOARD);
    }
}

Old snipped (it's a different app - not related to the code above):

@Override
public int onStartCommand(Intent intent, int flags, final int startId) {
    Log.d(TAG, "onStartCommand");

    String CHANNEL_ONE_ID = "com.kjtech.app.N1";
    String CHANNEL_ONE_NAME = "Channel One";
    NotificationChannel notificationChannel = null;
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        notificationChannel = new NotificationChannel(CHANNEL_ONE_ID,
                CHANNEL_ONE_NAME, IMPORTANCE_HIGH);
        notificationChannel.enableLights(true);
        notificationChannel.setLightColor(Color.RED);
        notificationChannel.setShowBadge(true);
        notificationChannel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        manager.createNotificationChannel(notificationChannel);
    }

    Bitmap icon = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
    Notification notification = new Notification.Builder(getApplicationContext())
            .setChannelId(CHANNEL_ONE_ID)
            .setContentTitle(getString(R.string.obd_service_notification_title))
            .setContentText(getString(R.string.service_notification_content))
            .setSmallIcon(R.mipmap.ic_launcher)
            .setLargeIcon(icon)
            .build();

    Intent notificationIntent = new Intent(getApplicationContext(), MainActivity.class);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    notification.contentIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, 0);

    startForeground(START_FOREGROUND_ID, notification);

    return START_STICKY;
}

As Constructor should be at the starting of the Class , you are facing the above issue . So, you can either change the name or if you want to use it as a constructor just copy the method at the beginning of the class.

If you are grepping through a git repository, I'd recommend you use git grep. You don't need to pass in -R or the path.

git grep pattern

That will show all matches from your current directory down.

try this:

SELECT ReportId, Email = 
    STUFF((SELECT ', ' + Email
           FROM your_table b 
           WHERE b.ReportId = a.ReportId 
          FOR XML PATH('')), 1, 2, '')
FROM your_table a
GROUP BY ReportId

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

You're hitting this data type compatibility restriction:

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

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

If you don't remember your password, then run this command in the Shell:

mysqladmin.exe -u root password NewPassword

where 'NewPassword' is your new password.

You have a parent element, you want to get all child of specific attribute 1. get the parent 2. get the parent nodename by using parent.nodeName.toLowerCase() convert the nodename to lower case e.g DIV will be div 3. for further specific purpose, get an attribute of the parent e.g parent.getAttribute("id"). this will give you id of the parent 4. Then use document.QuerySelectorAll(paret.nodeName.toLowerCase()+"#"_parent.getAttribute("id")+" input " ); if you want input children of the parent node

let parent = document.querySelector("div.classnameofthediv")_x000D_
let parent_node = parent.nodeName.toLowerCase()_x000D_
let parent_clas_arr = parent.getAttribute("class").split(" ");_x000D_
let parent_clas_str = '';_x000D_
  parent_clas_arr.forEach(e=>{_x000D_
     parent_clas_str +=e+'.';_x000D_
  })_x000D_
let parent_class_name = parent_clas_str.substr(0, parent_clas_str.length-1)  //remove the last dot_x000D_
let allchild = document.querySelectorAll(parent_node+"."+parent_class_name+" input")

Assuming MySQL (EDIT: posted before the SQL variant was supplied):

ALTER TABLE myTable ADD myNewColumn VARCHAR(255) AFTER myOtherColumn

The AFTER keyword tells MySQL where to place the new column. You can also use FIRST to flag the new column as the first column in the table.

If you really must use jQuery to solve this problem (NB: you shouldn't):

(function($) {
    $.rand = function(arg) {
        if ($.isArray(arg)) {
            return arg[$.rand(arg.length)];
        } else if (typeof arg === "number") {
            return Math.floor(Math.random() * arg);
        } else {
            return 4;  // chosen by fair dice roll
        }
    };
})(jQuery);

var items = [523, 3452, 334, 31, ..., 5346];
var item = jQuery.rand(items);

This plugin will return a random element if given an array, or a value from [0 .. n) given a number, or given anything else, a guaranteed random value!

For extra fun, the array return is generated by calling the function recursively based on the array's length :)

Old post, but I just ran into a very similar problem. After some experimenting, I found that you can do this with a single command:

kill $(ps aux | grep <process_name> | grep -v "grep" | cut -d " " -f2)

In OP's case, <process_name> would be "gedit file.txt".

When Atom auto-indent-detection got it hopelessly wrong and refused to let me type a literal Tab character, I eventually found the 'Force-Tab' extension - which gave me back control. I wanted to keep shift-tab for outdenting, so set ctrl-tab to insert a hard tab. In my keymap I added:

'atom-text-editor': 'ctrl-tab': 'force-tab:insert-actual-tab'

Use Comparator interface with methods introduced in JDK1.8: comparing and thenComparing, or more concrete methods: comparingXXX and thenComparingXXX.

For example, if we wanna sort a list of persons by their id firstly, then age, then name:

            Comparator<Person> comparator = Comparator.comparingLong(Person::getId)
                    .thenComparingInt(Person::getAge)
                    .thenComparing(Person::getName);
            personList.sort(comparator);

I use the vimrc in the python repo among other things:

http://svn.python.org/projects/python/trunk/Misc/Vim/vimrc

I also add

set softtabstop=4

I have my old config here that I'm updating

See var_export

It's much easier to just use jQuery, since this is just a task for university and you do not need to save code.

So, your code will look like:

function sendMyComment() {
    $('#addComment').append('<input type="hidden" name="video_id" id="video_id" value="' + $('#video_id').text() + '"/><input type="hidden" name="video_time" id="video_time" value="' + $('#time').text() +'"/>');
    $.ajax({
        type: 'POST',
        url: $('#addComment').attr('action'),
        data: $('form').serialize(), 
        success: function(response) { ... },
    });

}

use the get method in the url. If you want to pass over a variable called 'phone' as 0001112222:

<a href='whatever.php?phone=0001112222'>click</a>

then on the next page (whatever.php) you can access this var via:

$_GET['phone']
