Use this function from stringi package

stri_trans_totitle(c("zip code", "state", "final count"))
## [1] "Zip Code"      "State"       "Final Count" 

stri_trans_totitle("i like pizza very much")
## [1] "I Like Pizza Very Much"

I am a little late in the game, but I believe this is more functional and it works with any language, including Russian, German, Thai, Vietnamese etc. It will make uppercase anything after ' or - or . or ( or ) or space (obviously :).

CREATE FUNCTION [dbo].[fnToProperCase]( @name nvarchar(500) )
RETURNS nvarchar(500)
AS
BEGIN
declare @pos    int = 1
      , @pos2   int

if (@name <> '')--or @name = lower(@name) collate SQL_Latin1_General_CP1_CS_AS or @name = upper(@name) collate SQL_Latin1_General_CP1_CS_AS)
begin
    set @name = lower(rtrim(@name))
    while (1 = 1)
    begin
        set @name = stuff(@name, @pos, 1, upper(substring(@name, @pos, 1)))
        set @pos2 = patindex('%[- ''.)(]%', substring(@name, @pos, 500))
        set @pos += @pos2
        if (isnull(@pos2, 0) = 0 or @pos > len(@name))
            break
    end
end

return @name

It seems none of the answers format it in the actual title case: "How to Land Your Dream Job", "To Kill a Mockingbird", etc. so I've made my own method. Works best for English languages texts.

private final static Set<Character> TITLE_CASE_DELIMITERS = new HashSet<>();

  static {
    TITLE_CASE_DELIMITERS.add(' ');
    TITLE_CASE_DELIMITERS.add('.');
    TITLE_CASE_DELIMITERS.add(',');
    TITLE_CASE_DELIMITERS.add(';');
    TITLE_CASE_DELIMITERS.add('/');
    TITLE_CASE_DELIMITERS.add('-');
    TITLE_CASE_DELIMITERS.add('(');
    TITLE_CASE_DELIMITERS.add(')');
  }

  private final static Set<String> TITLE_SMALLCASED_WORDS = new HashSet<>();

  static {
    TITLE_SMALLCASED_WORDS.add("a");
    TITLE_SMALLCASED_WORDS.add("an");
    TITLE_SMALLCASED_WORDS.add("the");
    TITLE_SMALLCASED_WORDS.add("for");
    TITLE_SMALLCASED_WORDS.add("in");

  }

  public static String toCapitalizedWord(String oneWord) {
    if (oneWord.length() < 1) {
      return oneWord.toUpperCase();
    }
    return "" + Character.toTitleCase(oneWord.charAt(0)) + oneWord.substring(1).toLowerCase();
  }

  public static String toTitledWord(String oneWord) {
    if (TITLE_SMALLCASED_WORDS.contains(oneWord.toLowerCase())) {
      return oneWord.toLowerCase();
    }
    return toCapitalizedWord(oneWord);
  }

  public static String toTitleCase(String str) {
    StringBuilder result = new StringBuilder();
    StringBuilder oneWord = new StringBuilder();

    char previousDelimiter = 'x';
    /* on start, always move to upper case */
    for (char c : str.toCharArray()) {
      if (TITLE_CASE_DELIMITERS.contains(c)) {
        if (previousDelimiter == '-' || previousDelimiter == 'x') {
          result.append(toCapitalizedWord(oneWord.toString()));
        } else {
          result.append(toTitledWord(oneWord.toString()));
        }
        oneWord.setLength(0);
        result.append(c);
        previousDelimiter = c;
      } else {
        oneWord.append(c);
      }
    }
    if (previousDelimiter == '-' || previousDelimiter == 'x') {
      result.append(toCapitalizedWord(oneWord.toString()));
    } else {
      result.append(toTitledWord(oneWord.toString()));
    }
    return result.toString();
  }

  public static void main(String[] args) {
    System.out.println(toTitleCase("one year in paris"));

A complete and simple solution goes here:

String.prototype.replaceAt=function(index, replacement) {
        return this.substr(0, index) + replacement+ this.substr(index
  + replacement.length);
}
var str = 'k j g           u              i l  p';
function capitalizeAndRemoveMoreThanOneSpaceInAString() {
    for(let i  = 0; i < str.length-1; i++) {
        if(str[i] === ' ' && str[i+1] !== '')
            str = str.replaceAt(i+1, str[i+1].toUpperCase());
    }
    return str.replaceAt(0, str[0].toUpperCase()).replace(/\s+/g, ' ');
}
console.log(capitalizeAndRemoveMoreThanOneSpaceInAString(str));

First, convert your string into array by splitting it by spaces:

var words = str.split(' ');

Then use array.map to create a new array containing the capitalized words.

var capitalized = words.map(function(word) {
    return word.charAt(0).toUpperCase() + word.substring(1, word.length);
});

Then join the new array with spaces:

capitalized.join(" ");

function titleCase(str) {
  str = str.toLowerCase(); //ensure the HeLlo will become Hello at the end
  var words = str.split(" ");

  var capitalized = words.map(function(word) {
    return word.charAt(0).toUpperCase() + word.substring(1, word.length);
  });
  return capitalized.join(" ");
}

console.log(titleCase("I'm a little tea pot"));

NOTE:

This of course has a drawback. This will only capitalize the first letter of every word. By word, this means that it treats every string separated my spaces as 1 word.

Supposedly you have:

str = "I'm a little/small tea pot";

This will produce

I'm A Little/small Tea Pot

compared to the expected

I'm A Little/Small Tea Pot

In that case, using Regex and .replace will do the trick:

with ES6:

const capitalize = str => str.length
  ? str[0].toUpperCase() +
    str.slice(1).toLowerCase()
  : '';

const escape = str => str.replace(/./g, c => `\\${c}`);
const titleCase = (sentence, seps = ' _-/') => {
  let wordPattern = new RegExp(`[^${escape(seps)}]+`, 'g');
  
  return sentence.replace(wordPattern, capitalize);
};
console.log( titleCase("I'm a little/small tea pot.") );

or without ES6:

function capitalize(str) {
  return str.charAt(0).toUpperCase() + str.substring(1, str.length).toLowerCase();
}

function titleCase(str) {
  return str.replace(/[^\ \/\-\_]+/g, capitalize);
}

console.log(titleCase("I'm a little/small tea pot."));

XPath 1.0, which is what MS implements, does not have the idea of a default namespace. So try this:

XDocument xdoc = XDocument.Load(@"C:\SampleXML.xml");
XmlNamespaceManager xnm = new XmlNamespaceManager(new NameTable()); 
xnm.AddNamespace("x", "http://demo.com/2011/demo-schema");
Console.WriteLine(xdoc.XPathSelectElement("/x:Report/x:ReportInfo/x:Name", xnm) == null);

The function returns a FileStream object. So you could use it's return value to open your StreamWriter or close it using the proper method of the object:

File.Create(myPath).Close();

The first case is telling the web server that you are posting JSON data as in:

{ Name : 'John Smith', Age: 23}

The second option is telling the web server that you will be encoding the parameters in the URL as in:

Name=John+Smith&Age=23

JavaScript, as defined in your question, can't directly work with MySql. This is because it isn't running on the same computer.

JavaScript runs on the client side (in the browser), and databases usually exist on the server side. You'll probably need to use an intermediate server-side language (like PHP, Java, .Net, or a server-side JavaScript stack like Node.js) to do the query.

Here's a tutorial on how to write some code that would bind PHP, JavaScript, and MySql together, with code running both in the browser, and on a server:

http://www.w3schools.com/php/php_ajax_database.asp

And here's the code from that page. It doesn't exactly match your scenario (it does a query, and doesn't store data in the DB), but it might help you start to understand the types of interactions you'll need in order to make this work.

In particular, pay attention to these bits of code from that article.

Bits of Javascript:

xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();

Bits of PHP code:

mysql_select_db("ajax_demo", $con);
$result = mysql_query($sql);
// ...
$row = mysql_fetch_array($result)
mysql_close($con);

Also, after you get a handle on how this sort of code works, I suggest you use the jQuery JavaScript library to do your AJAX calls. It is much cleaner and easier to deal with than the built-in AJAX support, and you won't have to write browser-specific code, as jQuery has cross-browser support built in. Here's the page for the jQuery AJAX API documentation.

The code from the article

HTML/Javascript code:

<html>
<head>
<script type="text/javascript">
function showUser(str)
{
if (str=="")
  {
  document.getElementById("txtHint").innerHTML="";
  return;
  } 
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("txtHint").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();
}
</script>
</head>
<body>

<form>
<select name="users" onchange="showUser(this.value)">
<option value="">Select a person:</option>
<option value="1">Peter Griffin</option>
<option value="2">Lois Griffin</option>
<option value="3">Glenn Quagmire</option>
<option value="4">Joseph Swanson</option>
</select>
</form>
<br />
<div id="txtHint"><b>Person info will be listed here.</b></div>

</body>
</html>

PHP code:

<?php
$q=$_GET["q"];

$con = mysql_connect('localhost', 'peter', 'abc123');
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("ajax_demo", $con);

$sql="SELECT * FROM user WHERE id = '".$q."'";

$result = mysql_query($sql);

echo "<table border='1'>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Age</th>
<th>Hometown</th>
<th>Job</th>
</tr>";

while($row = mysql_fetch_array($result))
  {
  echo "<tr>";
  echo "<td>" . $row['FirstName'] . "</td>";
  echo "<td>" . $row['LastName'] . "</td>";
  echo "<td>" . $row['Age'] . "</td>";
  echo "<td>" . $row['Hometown'] . "</td>";
  echo "<td>" . $row['Job'] . "</td>";
  echo "</tr>";
  }
echo "</table>";

mysql_close($con);
?>

You can use Create USer to create a user

CREATE LOGIN sam
    WITH PASSWORD = '340$Uuxwp7Mcxo7Khy';
USE AdventureWorks;
CREATE USER sam FOR LOGIN sam;
GO 

and to Grant (Read-only access) you can use the following

GRANT SELECT TO sam

Hope that helps.

Works perfect for me with zooming and mouse movement.. you can customize it to mouse wheel up & down Njoy!!!

Here is fiddle for this Fiddle

This works the best for me:

http://www.asciitable.com/

Sometimes it's the simple answers that are the best ;+)

(?<=\[).+?(?=\])

Will capture content without brackets

• (?<=\[) - positive lookbehind for [

• .*? - non greedy match for the content

• (?=\]) - positive lookahead for ]

EDIT: for nested brackets the below regex should work:

(\[(?:\[??[^\[]*?\]))

Just modify one of the returned entities:

Customer c = (from x in dataBase.Customers
             where x.Name == "Test"
             select x).First();
c.Name = "New Name";
dataBase.SaveChanges();

Note, you can only update an entity (something that extends EntityObject, not something that you have projected using something like select new CustomObject{Name = x.Name}

your 8080 port is already used by another application 1/ you can try to find out which app is using it, using "netstat -aon" and stop the process; 2/ you can go to server.xml and change from port 8080 to another one (ex: 8081)

Use

$route.reload();

remember to inject $route to your controller.

You can use other characters besides "/" in substitution:

sed "s#$1#$2#g" -i FILE

>>> ','.join('{},{}'.format(i, i + 1) for i in range(1, 100, 4))
'1,2,5,6,9,10,13,14,17,18,21,22,25,26,29,30,33,34,37,38,41,42,45,46,49,50,53,54,57,58,61,62,65,66,69,70,73,74,77,78,81,82,85,86,89,90,93,94,97,98'

That was a quick and quite dirty solution.

Now, for a solution that is suitable for different kinds of progression problems:

def deltas():
    while True:
        yield 1
        yield 3
def numbers(start, deltas, max):
    i = start
    while i <= max:
        yield i
        i += next(deltas)
print(','.join(str(i) for i in numbers(1, deltas(), 100)))

And here are similar ideas implemented using itertools:

from itertools import cycle, takewhile, accumulate, chain

def numbers(start, deltas, max):
    deltas = cycle(deltas)
    numbers = accumulate(chain([start], deltas))
    return takewhile(lambda x: x <= max, numbers)

print(','.join(str(x) for x in numbers(1, [1, 3], 100)))

if you want to change color by hovering in the element, try this:

path:hover{
  fill:red;
}

Using a dict to grab headings then looping through gets you what you need cleanly.

import csv
ct = 0
cols_i_want = {'cost' : -1, 'date' : -1}
with open("file1.csv","rb") as source:
    rdr = csv.reader( source )
    with open("result","wb") as result:
        wtr = csv.writer( result )
        for row in rdr:
            if ct == 0:
              cc = 0
              for col in row:
                for ciw in cols_i_want: 
                  if col == ciw:
                    cols_i_want[ciw] = cc
                cc += 1
            wtr.writerow( (row[cols_i_want['cost']], row[cols_i_want['date']]) )
            ct += 1

Run xampp services by command line

To start apache service

sudo /Applications/XAMPP/xamppfiles/bin/apachectl start

To start mysql service

sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start

Both commands are working like charm :)

You can use the function system.

system("color *background**foreground*");

For background and foreground, type in a number from 0 - 9 or a letter from A - F.

For example:

system("color A1");
std::cout<<"hi"<<std::endl;

That would display the letters "hi" with a green background and blue text.

To see all the color choices, just type in:

system("color %");

to see what number or letter represents what color.

A simple query that shows only whether you are a SysAdmin or not :

IF IS_SRVROLEMEMBER ('sysadmin') = 1  
   print 'Current user''s login is a member of the sysadmin role'  
ELSE IF IS_SRVROLEMEMBER ('sysadmin') = 0  
   print 'Current user''s login is NOT a member of the sysadmin role'  
ELSE IF IS_SRVROLEMEMBER ('sysadmin') IS NULL  
   print 'ERROR: The server role specified is not valid.';

I just came across this query to describe a table in winsql

select NAME,TBNAME,COLTYPE,LENGTH,REMARKS,SCALE from sysibm.syscolumns

Warning: This might inflate executable file size a little bit and cost a little runtime performance. IMO, this would be better if golang has such feature like macro or function decorator.

If you want to mock functions without changing its API, the easiest way is to change the implementation a little bit:

func getPage(url string) string {
  if GetPageMock != nil {
    return GetPageMock()
  }

  // getPage real implementation goes here!
}

func downloader() {
  if GetPageMock != nil {
    return GetPageMock()
  }

  // getPage real implementation goes here!
}

var GetPageMock func(url string) string = nil
var DownloaderMock func() = nil

This way we can actually mock one function out of the others. For more convenient we can provide such mocking boilerplate:

// download.go
func getPage(url string) string {
  if m.GetPageMock != nil {
    return m.GetPageMock()
  }

  // getPage real implementation goes here!
}

func downloader() {
  if m.GetPageMock != nil {
    return m.GetPageMock()
  }

  // getPage real implementation goes here!
}

type MockHandler struct {
  GetPage func(url string) string
  Downloader func()
}

var m *MockHandler = new(MockHandler)

func Mock(handler *MockHandler) {
  m = handler
}

In test file:

// download_test.go
func GetPageMock(url string) string {
  // ...
}

func TestDownloader(t *testing.T) {
  Mock(&MockHandler{
    GetPage: GetPageMock,
  })

  // Test implementation goes here!

  Mock(new(MockHandler)) // Reset mocked functions
}

I found so many solution but I never got correct solution. But i have created some code to find minutes please check it.

<?php

  $time1 = "23:58";
  $time2 = "01:00";
  $time1 = explode(':',$time1);
  $time2 = explode(':',$time2);
  $hours1 = $time1[0];
  $hours2 = $time2[0];
  $mins1 = $time1[1];
  $mins2 = $time2[1];
  $hours = $hours2 - $hours1;
  $mins = 0;
  if($hours < 0)
  {
    $hours = 24 + $hours;
  }
  if($mins2 >= $mins1) {
        $mins = $mins2 - $mins1;
    }
    else {
      $mins = ($mins2 + 60) - $mins1;
      $hours--;
    }
    if($mins < 9)
    {
      $mins = str_pad($mins, 2, '0', STR_PAD_LEFT);
    }
    if($hours < 9)
    {
      $hours =str_pad($hours, 2, '0', STR_PAD_LEFT);
    }
echo $hours.':'.$mins;
?>

It gives output in hours and minutes for example 01 hour 02 minutes like 01:02

Caller-saved registers (AKA volatile registers, or call-clobbered) are used to hold temporary quantities that need not be preserved across calls.

For that reason, it is the caller's responsibility to push these registers onto the stack or copy them somewhere else if it wants to restore this value after a procedure call.

It's normal to let a call destroy temporary values in these registers, though.

Callee-saved registers (AKA non-volatile registers, or call-preserved) are used to hold long-lived values that should be preserved across calls.

When the caller makes a procedure call, it can expect that those registers will hold the same value after the callee returns, making it the responsibility of the callee to save them and restore them before returning to the caller. Or to not touch them.

I used Retrofit 2.0 for my register users, send multipart/form File image and text from register account

In my RegisterActivity, use an AsyncTask

//AsyncTask
private class Register extends AsyncTask<String, Void, String> {

    @Override
    protected void onPreExecute() {..}

    @Override
    protected String doInBackground(String... params) {
        new com.tequilasoft.mesasderegalos.dbo.Register().register(txtNombres, selectedImagePath, txtEmail, txtPassword);
        responseMensaje = StaticValues.mensaje ;
        mensajeCodigo = StaticValues.mensajeCodigo;
        return String.valueOf(StaticValues.code);
    }

    @Override
    protected void onPostExecute(String codeResult) {..}

And in my Register.java class is where use Retrofit with synchronous call

import android.util.Log;
import com.tequilasoft.mesasderegalos.interfaces.RegisterService;

Use $(parent).html(code) instead of parent.innerHTML = code.

The following also fixes scripts that use document.write and scripts loaded via src attribute. Unfortunately even this doesn't work with Google AdSense scripts.

var oldDocumentWrite = document.write;
var oldDocumentWriteln = document.writeln;
try {
    document.write = function(code) {
        $(parent).append(code);
    }
    document.writeln = function(code) {
        document.write(code + "<br/>");
    }
    $(parent).html(html); 
} finally {
    $(window).load(function() {
        document.write = oldDocumentWrite
        document.writeln = oldDocumentWriteln
    })
}

double check its getElements and not getElement

Not only did Matt Trout write an article about a REPL, he actually wrote one - Devel::REPL

I've used it a bit and it works fairly well, and it's under active development.

BTW, I have no idea why someone modded down the person who mentioned using "perl -e" from the console. This isn't really a REPL, true, but it's fantastically useful, and I use it all the time.

Or, building on Rusian L.'s suggestion, if the item you're searching for can be in the list more than once::

[Extension()]
public void ReplaceAll<T>(List<T> input, T search, T replace)
{
    int i = 0;
    do {
        i = input.FindIndex(i, s => EqualityComparer<T>.Default.Equals(s, search));

        if (i > -1) {
            FileSystem.input(i) = replace;
            continue;
        }

        break;  
    } while (true);
}

ddd is a graphical front-end to gdb that is pretty nice. One of the down sides is a classic X interface, but I seem to recall it being pretty intuitive.

There is one right method to remove only cache-files, which matches any KEY. For example:

grep -lr 'KEY: yahoo' /var/lib/nginx/cache | xargs rm -rf

This removes all cache-files, which matches to KEY "yahoo/*", if in nginx.conf was set:

proxy_cache_key $host$uri;

In engineering data, it is common to see the # symbol in the first column used to signal a comment.

I use the ostermiller CSV parsing library for Java to read and process such files. That library allows you to set the comment character. After the parse operation you get an array just containing the real data, no comments.

You could use jQuery to show the div, and set it at wherever your mouse is:

html:

<!DOCTYPE html>
<html>

  <head>
    <link href="style.css" rel="stylesheet" />
    <script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
  </head>

  <body>
    <div id="trigger">
      <h1>Hover me!</h1>
      <p>Ill show you wonderful things</p>
    </div>
    <div id="secret">
     shhhh
    </div>
    <script src="script.js"></script>
  </body>

</html>

styles:

#trigger {
  border: 1px solid black;
}
#secret {
  display:none;
  top:0;  
  position:absolute;
  background: grey;
  color:white;
  width: 50%;
}

js:

$("#trigger").hover(function(e){
    $("#secret").show().css('top', e.pageY + "px").css('left', e.pageX + "px");
  },function(e){
    $("#secret").hide()
})

You can find the example here Cheers! http://plnkr.co/edit/LAhs8X9F8N3ft7qFvjzy?p=preview

This code worked for me:

$(function() {
    $('[id=mycolors] option').filter(function() { 
        return ($(this).text() == 'Green'); //To select Green
    }).prop('selected', true);
});

With this HTML select list:

<select id="mycolors">
      <option value="1">Red</option>
      <option value="2">Green</option>
      <option value="3">Blue</option>
</select>

DateTime doesn't have a default key as an input. The default key should be an input to the Column function. Try this:

import datetime
from sqlalchemy import Column, Integer, DateTime
from sqlalchemy.ext.declarative import declarative_base

Base = declarative_base()

class Test(Base):
    __tablename__ = 'test'

    id = Column(Integer, primary_key=True)
    created_date = Column(DateTime, default=datetime.datetime.utcnow)

According to the subprocess.check_output() docs, the exception raised on error has an output attribute that you can use to access the error details:

try:
    subprocess.check_output(...)
except subprocess.CalledProcessError as e:
    print(e.output)

You should then be able to analyse this string and parse the error details with the json module:

if e.output.startswith('error: {'):
    error = json.loads(e.output[7:]) # Skip "error: "
    print(error['code'])
    print(error['message'])

Could you also increase post_max_size and see if it helps?

Uploading a file through an HTML form makes the upload treated like any other form element content, that's why increasing post_max_size should be required too.

Update : the final solution involved the command-line:

To export only 1 table you would do

mysqldump -u user_name -p your_password your_database_name your_table_name > dump_file.sql

and to import :

mysql -u your_user -p your_database < dump_file.sql 

'drop table your_tabe_name;' can also be added at the top of the import script if it's not already there, to ensure the table gets deleted before the script creates and fill it

Where, I solved this problem by adding the visibility attribute to the CSS code, it works on my website

Original code:

#zo2-body-wrap .introText .images:before_x000D_
{_x000D_
background:rgba(136,136,136,0.7);_x000D_
width:100%;_x000D_
height:100%;_x000D_
content:"";_x000D_
position:absolute;_x000D_
top:0;_x000D_
opacity:0;_x000D_
transition:all 0.2s ease-in-out 0s;_x000D_
}

Fixed iOS touch code:

#zo2-body-wrap .introText .images:before_x000D_
{_x000D_
background:rgba(136,136,136,0.7);_x000D_
width:100%;_x000D_
height:100%;_x000D_
content:"";_x000D_
position:absolute;_x000D_
top:0;_x000D_
visibility:hidden;_x000D_
opacity:0;_x000D_
transition:all 0.2s ease-in-out 0s;_x000D_
}

If your code is already running in a background thread, pause the thread using this method in Foundation: Thread.sleep(forTimeInterval:)

For example:

DispatchQueue.global(qos: .userInitiated).async {

    // Code is running in a background thread already so it is safe to sleep
    Thread.sleep(forTimeInterval: 4.0)
}

(See other answers for suggestions when your code is running on the main thread.)

You can see the list of supported codecs in the official documentation:

Just for fun:

var mystring = "this,is,a,test"  
var newchar = '|'
mystring = mystring.split(',').join(newchar);

 WHERE cast(timestamp as date) = '2012-05-05'

This will check for empty textarea as well as will not allow only Spaces in textarea coz that looks empty too.

 var txt_msg = $("textarea").val();

 if (txt_msg.replace(/^\s+|\s+$/g, "").length == 0 || txt_msg=="") {
    return false;
  }

This appears to be a variable naming convention in Node.js control-flow code, where a reference to the next function to execute is given to a callback for it to kick-off when it's done.

See, for example, the code samples here:

• http://blog.mixu.net/2011/02/02/essential-node-js-patterns-and-snippets/

Let's look at the example you posted:

function loadUser(req, res, next) {
  if (req.session.user_id) {
    User.findById(req.session.user_id, function(user) {
      if (user) {
        req.currentUser = user;
        return next();
      } else {
        res.redirect('/sessions/new');
      }
    });
  } else {
    res.redirect('/sessions/new');
  }
}

app.get('/documents.:format?', loadUser, function(req, res) {
  // ...
});

The loadUser function expects a function in its third argument, which is bound to the name next. This is a normal function parameter. It holds a reference to the next action to perform and is called once loadUser is done (unless a user could not be found).

There's nothing special about the name next in this example; we could have named it anything.

You haven't posted the findvertex method, but Access Reading Violation with an offset like 0x00000048 means that the Vertex* f; in your getCost function is receiving null, and when trying to access the member adj in the null Vertex pointer (that is, in f), it is offsetting to adj (in this case, 72 bytes ( 0x48 bytes in decimal )), it's reading near the 0 or null memory address.

Doing a read like this violates Operating-System protected memory, and more importantly means whatever you're pointing at isn't a valid pointer. Make sure findvertex isn't returning null, or do a comparisong for null on f before using it to keep yourself sane (or use an assert):

assert( f != null ); // A good sanity check

EDIT:

If you have a map for doing something like a find, you can just use the map's find method to make sure the vertex exists:

Vertex* Graph::findvertex(string s)
{
    vmap::iterator itr = map1.find( s );
    if ( itr == map1.end() )
    {
        return NULL;
    }
    return itr->second;
}

Just make sure you're still careful to handle the error case where it does return NULL. Otherwise, you'll keep getting this access violation.

select 
  id,
  case 
    when report_type = 'P' 
    then amount 
    when report_type = 'N' 
    then -amount 
    else null 
  end
from table

Please do notice that all platform requirements are taken from the name of the *.whl file!

So be very careful with renaming of *.whl package. I occasionally renamed my newly compiled tensorflow package from

tensorflow-1.11.0-cp36-cp36m-linux_x86_64.whl

to

tensorflow-1.11.0-cp36-cp36m-linux_x86_64_gpu.whl

just to remind myself about gpu support and struggled with

tensorflow-1.11.0-cp36-cp36m-linux_x86_64_gpu.whl is not a supported wheel on this platform.

error for about half an hour.

Use MyEnum enumValue = MyEnum.values()[x];

You could try the subplot_tool()

plt.subplot_tool()

Try this code it is already built in c#

int lastDay = DateTime.DaysInMonth (2014, 2);

and the first day is always 1.

Good Luck!

As long as your List is a concrete class, you can simply call the contains() method as long as you have implemented your equals() method on MyItem.

// given 
// some input ... you to complete

// when
List<MyItems> results = service.getMyItems();

// then
assertTrue(results.contains(new MyItem("foo")));
assertTrue(results.contains(new MyItem("bar")));

Assumes you have implemented a constructor that accepts the values you want to assert on. I realise this isn't on a single line, but it's useful to know which value is missing rather than checking both at once.

This is the correct way.

>>> x = [ ['0,0', '0,1'], ['1,0', '1,1'], ['2,0', '2,1'] ]
>>> for i in range(len(x)):
        for j in range(len(x[i])):
                print(x[i][j])


0,0
0,1
1,0
1,1
2,0
2,1
>>> 

This worked for me:

    import re
    text = 'how are u? umberella u! u. U. U@ U# u '
    rex = re.compile(r'\bu\b', re.IGNORECASE)
    print(rex.sub('you', text))

It pre-compiles the regular expression and makes use of re.IGNORECASE so that we don't have to worry about case in our regular expression! BTW, I love the funky spelling of umbrella! :-)

Had troubles as well. On Linux I used Ctrl+X (and Y to confirm) and then I was back on the shell ready to pull/push.

On Windows GIT Bash Ctrl+X would do nothing and found out it works quite like vi/vim. Press i to enter inline insert mode. Type the description at the very top, press esc to exit insert mode, then type :x! (now the cursor is at the bottom) and hit enter to save and exit.

If typing :q! instead, will exit the editor without saving (and commit will be aborted)

As Per documentation of moment js,

There is Precise Range plugin, written by Rob Dawson, can be used to display exact, human-readable representations of date/time ranges, url :http://codebox.org.uk/pages/moment-date-range-plugin

moment("2014-01-01 12:00:00").preciseDiff("2015-03-04 16:05:06");
// 1 year 2 months 3 days 4 hours 5 minutes 6 seconds

moment.preciseDiff("2014-01-01 12:00:00", "2014-04-20 12:00:00");
// 3 months 19 days

You need to call the AddAddress method once for every recipient. Like so:

$mail->AddAddress('[email protected]', 'Person One');
$mail->AddAddress('[email protected]', 'Person Two');
// ..

Better yet, add them as Carbon Copy recipients.

$mail->AddCC('[email protected]', 'Person One');
$mail->AddCC('[email protected]', 'Person Two');
// ..

To make things easy, you should loop through an array to do this.

$recipients = array(
   '[email protected]' => 'Person One',
   '[email protected]' => 'Person Two',
   // ..
);
foreach($recipients as $email => $name)
{
   $mail->AddCC($email, $name);
}

There is a new library called ipyvolume that may do what you want, the documentation shows live demos. The current version doesn't do meshes and lines, but master from the git repo does (as will version 0.4). (Disclaimer: I'm the author)

Having a Text file content:

line 1
line 2
line 3

We can use this Python script in the same directory of the txt above

>>> with open("myfile.txt", encoding="utf-8") as file:
...     x = [l.rstrip("\n") for l in file]
>>> x
['line 1','line 2','line 3']

Using append:

x = []
with open("myfile.txt") as file:
    for l in file:
        x.append(l.strip())

Or:

>>> x = open("myfile.txt").read().splitlines()
>>> x
['line 1', 'line 2', 'line 3']

Or:

>>> x = open("myfile.txt").readlines()
>>> x
['linea 1\n', 'line 2\n', 'line 3\n']

Or:

def print_output(lines_in_textfile):
    print("lines_in_textfile =", lines_in_textfile)

y = [x.rstrip() for x in open("001.txt")]
print_output(y)

with open('001.txt', 'r', encoding='utf-8') as file:
    file = file.read().splitlines()
    print_output(file)

with open('001.txt', 'r', encoding='utf-8') as file:
    file = [x.rstrip("\n") for x in file]
    print_output(file)

output:

lines_in_textfile = ['line 1', 'line 2', 'line 3']
lines_in_textfile = ['line 1', 'line 2', 'line 3']
lines_in_textfile = ['line 1', 'line 2', 'line 3']

public class Main {
 public static void main(String args[]) {
   String format = "|%1$-10s|%2$-10s|%3$-20s|\n";
   System.out.format(format, "A", "AA", "AAA");
   System.out.format(format, "B", "", "BBBBB");
   System.out.format(format, "C", "CCCCC", "CCCCCCCC");

   String ex[] = { "E", "EEEEEEEEEE", "E" };

   System.out.format(String.format(format, (Object[]) ex));
 }
}

differece in sizes of input doesnt effect the output

You can multiply numpy arrays by scalars and it just works.

>>> import numpy as np
>>> np.array([1, 2, 3]) * 2
array([2, 4, 6])
>>> np.array([[1, 2, 3], [4, 5, 6]]) * 2
array([[ 2,  4,  6],
       [ 8, 10, 12]])

This is also a very fast and efficient operation. With your example:

>>> a_1 = np.array([1.0, 2.0, 3.0])
>>> a_2 = np.array([[1., 2.], [3., 4.]])
>>> b = 2.0
>>> a_1 * b
array([2., 4., 6.])
>>> a_2 * b
array([[2., 4.],
       [6., 8.]])

Although you can use the

{{ game.gameDate|date('Y-m-d') }}

approach, keep in mind that this version does not honor the user locale, which should not be a problem with a site used by only users of one nationality. International users should display the game date totally different, like extending the \DateTime class, and adding a __toString() method to it that checks the locale and acts accordingly.

Edit:

As pointed out by @Nic in a comment, if you use the Intl extension of Twig, you will have a localizeddate filter available, which shows the date in the user’s locale. This way you can drop my previous idea of extending \DateTime.

}

Also Create an Interface with

public interface DrawableClickListener {

    public static enum DrawablePosition { TOP, BOTTOM, LEFT, RIGHT };
    public void onClick(DrawablePosition target); 
    }

Still if u need any help, comment

Also set the drawableClickListener on the view in activity file.

editText.setDrawableClickListener(new DrawableClickListener() {
        
         
        public void onClick(DrawablePosition target) {
            switch (target) {
            case LEFT:
                //Do something here
                break;

            default:
                break;
            }
        }
        
    });

Something else to check is make sure viewstate is on (I just solved this yesterday). If you don't have viewstate on, the gridview will be blank until you load it again.

You're not assigning the parsed float back to your value var:

value = parseFloat(value).toFixed(2);

should fix things up.

Firstly you need to install a SSH server in the images you wish to ssh-into. You can use a base image for all your container with the ssh server installed. Then you only have to run each container mapping the ssh port (default 22) to one to the host's ports (Remote Server in your image), using -p <hostPort>:<containerPort>. i.e:

docker run -p 52022:22 container1 
docker run -p 53022:22 container2

Then, if ports 52022 and 53022 of host's are accessible from outside, you can directly ssh to the containers using the ip of the host (Remote Server) specifying the port in ssh with -p <port>. I.e.:

ssh -p 52022 myuser@RemoteServer --> SSH to container1

ssh -p 53022 myuser@RemoteServer --> SSH to container2

For the question

How can i run a jar file in command prompt but with arguments

.

To pass arguments to the jar file at the time of execution

java -jar myjar.jar arg1 arg2

In the main() method of "Main-Class" [mentioned in the manifest.mft file]of your JAR file. you can retrieve them like this:

String arg1 = args[0];
String arg2 = args[1];

Here is the code:

import os
existGDBPath = r'T:\Data\DBDesign\DBDesign_93_v141b.mdb'
wkspFldr = os.path.dirname(existGDBPath)
print wkspFldr # T:\Data\DBDesign

The easiest solution is to use percentages. This isn't exactly the answer you were looking for since you asked for pixel-precision, but if you just need something to have a little padding between the right edge and the image, giving something a position of 99% usually works well enough.

Code:

/* aligns image to the vertical center and horizontal right of its container with a small amount of padding between the right edge */
div.middleleft {
  background: url("/images/source.jpg") 99% center no-repeat;
}

Checkout intent properties like no history , clear back stack etc ... Intent.setFlags

Intent mStartActivity = new Intent(HomeActivity.this, SplashScreen.class);
int mPendingIntentId = 123456;
PendingIntent mPendingIntent = PendingIntent.getActivity(HomeActivity.this, mPendingIntentId, mStartActivity,
PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager mgr = (AlarmManager) HomeActivity.this.getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 100, mPendingIntent);
System.exit(0);

What it mentions as you type adb?

step1. >adb shell
step2. >cd data/data
step3. >ls -l|grep "your app package here"
step4. >cd "your app package here"
step5. >sqlite3 xx.db

Its just better to create a routing component that would handle all your routes! From the angular website documentation! That's good practice!

ng generate module app-routing --flat --module=app

The above CLI generates a routing module and adds to your app module, all you need to do from the generated component is to declare your routes, also don't forget to add this:

exports: [
    RouterModule
  ],

to your ng-module decorator as it doesn't come with the generated app-routing module by default!

One more option - mod_qos

Not simple to configure - but powerful.

http://opensource.adnovum.ch/mod_qos/

As others have mentioned, you could use a comparison function, but you can also overload the < operator and the default less<T> functor will work as well:

struct data {
    string word;
    int number;
    bool operator < (const data& rhs) const {
        return word.size() < rhs.word.size();
    }
};

Then it's just:

std::sort(info.begin(), info.end());

Edit

As James McNellis pointed out, sort does not actually use the less<T> functor by default. However, the rest of the statement that the less<T> functor will work as well is still correct, which means that if you wanted to put struct datas into a std::map or std::set this would still work, but the other answers which provide a comparison function would need additional code to work with either.

I was too getting this error, but i have solved this using below concept.

1. Restart your intellij idea community edition.
2. After that, go on the right hand corner to set the configuration for java.

3. choose configuration setting for all module. then re-run the code. It will work.

This error comes because of not configuring java properly.

I really recommend using some sort of library, but you asked for it, you get it:

var p = document.querySelector('p'); // element to make resizable

p.addEventListener('click', function init() {
    p.removeEventListener('click', init, false);
    p.className = p.className + ' resizable';
    var resizer = document.createElement('div');
    resizer.className = 'resizer';
    p.appendChild(resizer);
    resizer.addEventListener('mousedown', initDrag, false);
}, false);

var startX, startY, startWidth, startHeight;

function initDrag(e) {
   startX = e.clientX;
   startY = e.clientY;
   startWidth = parseInt(document.defaultView.getComputedStyle(p).width, 10);
   startHeight = parseInt(document.defaultView.getComputedStyle(p).height, 10);
   document.documentElement.addEventListener('mousemove', doDrag, false);
   document.documentElement.addEventListener('mouseup', stopDrag, false);
}

function doDrag(e) {
   p.style.width = (startWidth + e.clientX - startX) + 'px';
   p.style.height = (startHeight + e.clientY - startY) + 'px';
}

function stopDrag(e) {
    document.documentElement.removeEventListener('mousemove', doDrag, false);
    document.documentElement.removeEventListener('mouseup', stopDrag, false);
}

Demo

Remember that this may not run in all browsers (tested only in Firefox, definitely not working in IE <9).

Just use public_path() it will find public folder and address it itself.

Python 2.X

There is a unicode-csv library which should solve your problems, with added benefit of not naving to write any new csv-related code.

Here is a example from their readme:

>>> import unicodecsv
>>> from cStringIO import StringIO
>>> f = StringIO()
>>> w = unicodecsv.writer(f, encoding='utf-8')
>>> w.writerow((u'é', u'ñ'))
>>> f.seek(0)
>>> r = unicodecsv.reader(f, encoding='utf-8')
>>> row = r.next()
>>> print row[0], row[1]
é ñ

Python 3.X

In python 3 this is supported out of the box by the build-in csv module. See this example:

import csv
with open('some.csv', newline='', encoding='utf-8') as f:
    reader = csv.reader(f)
    for row in reader:
        print(row)

You say that the matrices are the same dimensions, and yet you are trying to perform matrix multiplication on them. Multiplication of matrices with the same dimension is only possible if they are square. In your case, you get an assertion error, because the dimensions are not square. You have to be careful when multiplying matrices, as there are two possible meanings of multiply.

Matrix multiplication is where two matrices are multiplied directly. This operation multiplies matrix A of size [a x b] with matrix B of size [b x c] to produce matrix C of size [a x c]. In OpenCV it is achieved using the simple * operator:

C = A * B

Element-wise multiplication is where each pixel in the output matrix is formed by multiplying that pixel in matrix A by its corresponding entry in matrix B. The input matrices should be the same size, and the output will be the same size as well. This is achieved using the mul() function:

output = A.mul(B);

You can, use:

if (date >= startDate && date<= EndDate) { return true; }

If you installed it with homebrew, the binary will be somewhere like

/usr/local/Cellar/mysql/5.6.10/bin/mysqld

which means you can start it with

/usr/local/Cellar/mysql/5.6.10/support-files/mysql.server start

and stop it with

/usr/local/Cellar/mysql/5.6.10/support-files/mysql.server stop

Edit: As Jacob Raccuia mentioned, make sure you put the appropriate version of MySQL in the path.

in oracle SQL you would do this:

SELECT
    DATA_TYPE
FROM
    all_tab_columns 
WHERE
    table_name = 'TABLE NAME' -- in uppercase
AND column_name = 'COLUMN NAME' -- in uppercase

You need install pysocks , my version is 1.0 and the code works for me:

import socket
import socks
import requests
ip='localhost' # change your proxy's ip
port = 0000 # change your proxy's port
socks.setdefaultproxy(socks.PROXY_TYPE_SOCKS5, ip, port)
socket.socket = socks.socksocket
url = u'http://ajax.googleapis.com/ajax/services/search/images?v=1.0&q=inurl%E8%A2%8B'
print(requests.get(url).text)

Event listeners

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

1. Scope event listeners registered via $on:

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

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

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

$scope.$destroy()

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

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

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

element.remove()

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

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

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

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

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

What to do when a directive is "destroyed"

This depends on how the directive is "destroyed".

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

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

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

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

Both event listeners will be removed automatically.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

$(".clscss-row").each(function () {
if ($(this).find(".po-checkbox").not(":checked")) {
               // enter your code here
            } });

Config file changes are required to enable connections via localhost.

To connect through remote IPs, Login as a "root" user and run the below queries in mysql.

CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';

GRANT ALL PRIVILEGES ON *.* TO 'username'@'localhost' WITH GRANT OPTION;

CREATE USER 'username'@'%' IDENTIFIED BY 'password';

GRANT ALL PRIVILEGES ON *.* TO 'username'@'%' WITH GRANT OPTION;

FLUSH PRIVILEGES;

This will create a new user that is accessible on localhost as well as from remote IPs.

Also comment the below line from your my.cnf file located in /etc/mysql/my.cnf

bind-address = 127.0.0.1

Restart your mysql using

sudo service mysql restart

Now you should be able to connect remotely to your mysql.

N=np.floor(np.divide(l,delta))
...
for j in range(N[i]/2):

N[i]/2 will be a float64 but range() expects an integer. Just cast the call to

for j in range(int(N[i]/2)):

On Mac I could not find the pgrep and pkill neither was killall working so wrote a simple one liner script:-

export pid=`ps | grep process_name | awk 'NR==1{print $1}' | cut -d' ' -f1`;kill $pid

If there's an easier way of doing this then please share.

This should help stringify deep objects by leaving out recursive Window and Node objects.

function stringifyObject(e) {
  const obj = {};
  for (let k in e) {
    obj[k] = e[k];
  }

  return JSON.stringify(obj, (k, v) => {
    if (v instanceof Node) return 'Node';
    if (v instanceof Window) return 'Window';
    return v;
  }, ' ');
}

Take This as an alternate to startActivityforResult.But keep in mind that for such cases this approach can be expensive in terms of performance but in some cases you might need to use.

In Activity2,

@Override
public void onBackPressed() {
String data = mEditText.getText();
SharedPreferences sp = getSharedPreferences("LoginInfos", 0);
Editor editor = sp.edit();
editor.putString("email",data);
editor.commit();
}

In Activity1,

 @Override
public void onResume() {
SharedPreferences sp = getSharedPreferences("LoginInfos", 0);
String  dataFromOtherAct= sp.getString("email", "no email");
} 

I can carry out some cleanups before exiting. What is the best way of doing this Thats is the real goal: trap exit, to make your own stuff. And neigther answers above not makeing it right. Because, Ctrl+C is just one of many ways to exiting app.

What in dotnet c# is needed for it - so called cancellation token passed to Host.RunAsync(ct) and then, in exit signals traps, for Windows it would be

    private static readonly CancellationTokenSource cts = new CancellationTokenSource();
    public static int Main(string[] args)
    {
        // For gracefull shutdown, trap unload event
        AppDomain.CurrentDomain.ProcessExit += (sender, e) =>
        {
            cts.Cancel();
            exitEvent.Wait();
        };

        Console.CancelKeyPress += (sender, e) =>
        {
            cts.Cancel();
            exitEvent.Wait();
        };

        host.RunAsync(cts);
        Console.WriteLine("Shutting down");
        exitEvent.Set();
        return 0;
     }

Here is an expanded answer. A DecoratedBox is what you need to add a border, but I am using a Container for the convenience of adding margin and padding.

Here is the general setup.

Widget myWidget() {
  return Container(
    margin: const EdgeInsets.all(30.0),
    padding: const EdgeInsets.all(10.0),
    decoration: myBoxDecoration(), //             <--- BoxDecoration here
    child: Text(
      "text",
      style: TextStyle(fontSize: 30.0),
    ),
  );
}

where the BoxDecoration is

BoxDecoration myBoxDecoration() {
  return BoxDecoration(
    border: Border.all(),
  );
}

Border width

These have a border width of 1, 3, and 10 respectively.

BoxDecoration myBoxDecoration() {
  return BoxDecoration(
    border: Border.all(
      width: 1, //                   <--- border width here
    ),
  );
}

Border color

These have a border color of

• Colors.red
• Colors.blue
• Colors.green

Code

BoxDecoration myBoxDecoration() {
  return BoxDecoration(
    border: Border.all(
      color: Colors.red, //                   <--- border color
      width: 5.0,
    ),
  );
}

Border side

These have a border side of

• left (3.0), top (3.0)
• bottom (13.0)
• left (blue[100], 15.0), top (blue[300], 10.0), right (blue[500], 5.0), bottom (blue[800], 3.0)

Code

BoxDecoration myBoxDecoration() {
  return BoxDecoration(
    border: Border(
      left: BorderSide( //                   <--- left side
        color: Colors.black,
        width: 3.0,
      ),
      top: BorderSide( //                    <--- top side
        color: Colors.black,
        width: 3.0,
      ),
    ),
  );
}

Border radius

These have border radii of 5, 10, and 30 respectively.

BoxDecoration myBoxDecoration() {
  return BoxDecoration(
    border: Border.all(
      width: 3.0
    ),
    borderRadius: BorderRadius.all(
        Radius.circular(5.0) //                 <--- border radius here
    ),
  );
}

Going on

DecoratedBox/BoxDecoration are very flexible. Read Flutter — BoxDecoration Cheat Sheet for many more ideas.

This happened for me when I was trying to stash my changes, but then my changes had conflicts with my branch's current state.

So I did git reset --mixed and then resolved the git conflict and stashed again.

I had the same problem. After several tries, I realized that connecting the sql server with windows authentication resolved the issue.

You're only adding the File object to the JSON object. The File object only contains meta information about the file: Path, name and so on.

You must load the image and read the bytes from it. Then put these bytes into the JSON object.

You can %HOMEDRIVE%%HOMEPATH% for the drive + \docs settings\username or \users\username.

select s.sid as "Sid", s.serial# as "Serial#", nvl(s.username, ' ') as "Username", s.machine as "Machine", s.schemaname as "Schema name", s.logon_time as "Login time", s.program as "Program", s.osuser as "Os user", s.status as "Status", nvl(s.process, ' ') as "OS Process id"
from v$session s
where nvl(s.username, 'a') not like 'a' and status like 'ACTIVE'
order by 1,2

This query attempts to filter out all background processes.

Add:

using System.Linq;

to the top of your file.

And then:

Car[] carList = ...
var carMake = 
    from item in carList
    where item.Model == "bmw" 
    select item.Make;

or if you prefer the fluent syntax:

var carMake = carList
    .Where(item => item.Model == "bmw")
    .Select(item => item.Make);

Things to pay attention to:

• The usage of item.Make in the select clause instead if s.Make as in your code.
• You have a whitespace between item and .Model in your where clause

• Caucho Resin 4.0.2 (not yet tried) V 4.0.25 supports RFC6455
• Tomcat 7.0.27 now supports it V 7.0.28 supports RFC6455
• Tomcat 8.x has native support for websockets RFC6455 and is JSR 356 compliant
• JSR 356 included in Java EE 7 will define the Java API for WebSocket, but is not yet stable and complete. See Arun GUPTA's article WebSocket and Java EE 7 - Getting Ready for JSR 356 (TOTD #181) and QCon presentation (from 00:37:36 to 00:46:53) for more information on progress.

1. Ensure that you have your Dbms Output window open through the view option in the menubar.
2. Click on the green '+' sign and add your database name.
3. Write 'DBMS_OUTPUT.ENABLE;' within your procedure as the first line. Hope this solves your problem.

You're very close:

while IFS=$'\t' read -r -a myArray
do
 echo "${myArray[0]}"
 echo "${myArray[1]}"
 echo "${myArray[2]}"
done < myfile

(The -r tells read that \ isn't special in the input data; the -a myArray tells it to split the input-line into words and store the results in myArray; and the IFS=$'\t' tells it to use only tabs to split words, instead of the regular Bash default of also allowing spaces to split words as well. Note that this approach will treat one or more tabs as the delimiter, so if any field is blank, later fields will be "shifted" into earlier positions in the array. Is that O.K.?)

Sometimes changing the header is not enough, some sites check the referer as well:

curl -v \
     -H 'Host: restapi.some-site.com' \
     -H 'Connection: keep-alive' \
     -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8' \
     -H 'Accept-Language: en-GB,en-US;q=0.8,en;q=0.6' \
     -e localhost \
     -A 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.65 Safari/537.36' \
     'http://restapi.some-site.com/getsomething?argument=value&argument2=value'

In this example the referer (-e or --referer in curl) is 'localhost'.

1. Install nodemon globally:

   C:\>npm install -g nodemon
   

2. Get prefix:

   C:\>npm config get prefix
   

   You will get output like following in your console:

   C:\Users\Family\.node_modules_global
   

   Copy it.

3. Set Path.
   Go to Advance System Settings → Environment Variable → Click New (Under User Variables) → Pop up form will be displayed → Pass the following values:

   variable name = path,
   variable value = Copy output from your console
   

4. Now Run Nodemon:

   C:\>nodemon .
   

First solution is Use range_based for loop, like:

Note: When range_expression’s type is std::map then a range_declaration’s type is std::pair.

for ( range_declaration : range_expression )      
  //loop_statement

Code 1:

typedef std::map<std::string, std::map<std::string, std::string>> StringToStringMap;

StringToStringMap my_map;

for(const auto &pair1 : my_map) 
{
   // Type of pair1 is std::pair<std::string, std::map<std::string, std::string>>
   // pair1.first point to std::string (first key)
   // pair1.second point to std::map<std::string, std::string> (inner map)
   for(const auto &pair2 : pair1.second) 
   {
       // pair2.first is the second(inner) key
       // pair2.second is the value
   }
}

The Second Solution:

Code 2

typedef std::map<std::string, std::string> StringMap;
typedef std::map<std::string, StringMap> StringToStringMap;

StringToStringMap my_map;

for(StringToStringMap::iterator it1 = my_map.begin(); it1 != my_map.end(); it1++)
{
    // it1->first point to first key
    // it2->second point to inner map
    for(StringMap::iterator it2 = it1->second.begin(); it2 != it1->second.end(); it2++)
     {
        // it2->second point to value
        // it2->first point to second(inner) key 
     }
 }

This did it for me

Intent callGPSSettingIntent = new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivityForResult(callGPSSettingIntent);

When they press back it goes back to my app.

Add a Primary Key (code below)

Run the correct delete (code below)

Consider WHY you woudln't want to keep that primary key.

Assuming MSSQL or compatible:

ALTER TABLE Employee ADD EmployeeID int identity(1,1) PRIMARY KEY;

WHILE EXISTS (SELECT COUNT(*) FROM Employee GROUP BY EmpID, EmpSSN HAVING COUNT(*) > 1)
BEGIN
    DELETE FROM Employee WHERE EmployeeID IN 
    (
        SELECT MIN(EmployeeID) as [DeleteID]
        FROM Employee
        GROUP BY EmpID, EmpSSN
        HAVING COUNT(*) > 1
    )
END

If the effect you want is to center in the center of the screen no matter where you've scrolled to, it's even simpler than that:

In your CSS use (for example)

div.centered{
  width: 100px;
  height: 50px;
  position:fixed; 
  top: calc(50% - 25px); // half of width
  left: calc(50% - 50px); // half of height
}

No JS required.

Gmail started basic support for style tags in the head area. Found nothing official yet but you can easily try it yourself.
It seems to ignore class and id selectors but basic element selectors work.

<!doctype html>
<html>
  <head>
    <style type="text/css">
      p{font-family:Tahoma,sans-serif;font-size:12px;margin:0}  
    </style>
  </head>
  <body>
    <p>Email content here</p>
  </body>
</html>

it will create a style tag in its own head area limited to the div containing the mail body

<style>div.m14623dcb877eef15 p{font-family:Tahoma,sans-serif;font-size:12px;margin:0}</style>

Why should I use it instead of optparse? Are their new features I should know about?

@Nicholas's answer covers this well, I think, but not the more "meta" question you start with:

Why has yet another command-line parsing module been created?

That's the dilemma number one when any useful module is added to the standard library: what do you do when a substantially better, but backwards-incompatible, way to provide the same kind of functionality emerges?

Either you stick with the old and admittedly surpassed way (typically when we're talking about complicated packages: asyncore vs twisted, tkinter vs wx or Qt, ...) or you end up with multiple incompatible ways to do the same thing (XML parsers, IMHO, are an even better example of this than command-line parsers -- but the email package vs the myriad old ways to deal with similar issues isn't too far away either;-).

You may make threatening grumbles in the docs about the old ways being "deprecated", but (as long as you need to keep backwards compatibility) you can't really take them away without stopping large, important applications from moving to newer Python releases.

(Dilemma number two, not directly related to your question, is summarized in the old saying "the standard library is where good packages go to die"... with releases every year and a half or so, packages that aren't very, very stable, not needing releases any more often than that, can actually suffer substantially by being "frozen" in the standard library... but, that's really a different issue).

To send json to the server, you first have to create json

function sendData() {
    $.ajax({
        url: '/helloworld',
        type: 'POST',
        contentType: 'application/json',
        data: JSON.stringify({
            name:"Bob",
            ...
        }),
        dataType: 'json'
    });
}

This is how you would structure the ajax request to send the json as a post var.

function sendData() {
    $.ajax({
        url: '/helloworld',
        type: 'POST',
        data: { json: JSON.stringify({
            name:"Bob",
            ...
        })},
        dataType: 'json'
    });
}

The json will now be in the json post var.

To connect to a new server, you click on home + add new connection. Put IP or webserver URL in new connection.

The question is old, but it seems that there are people who have the same concerns.

What do you think of the opinion that 'the alpha property of UIColor and the opacity property of Interface Builder are applied differently in code'?

The two views created in Interface Builder were initially different colors, but had to be the same color when the conditions changed. So, I had to set the background color of one view in code, and set a different value to make the background color of both views the same.

As an actual example, the background color of Interface Builder was 0x121212 and the Opacity value was 80%(in Amani Elsaed's image :: Red: 18, Green: 18, Blue: 18, Hex Color #: [121212], Opacity: 80), In the code, I set the other view a background color of 0x121212 with an alpha value of 0.8.

self.myFuncView.backgroundColor = UIColor(red: 18, green: 18, blue: 18, alpha: 0.8)

extension is

extension UIColor {
    convenience init(red: Int, green: Int, blue: Int, alpha: CGFloat = 1.0) {
        self.init(red: CGFloat(red) / 255.0,
                  green: CGFloat(green) / 255.0,
                  blue: CGFloat(blue) / 255.0,
                  alpha: alpha)
    }
}

However, the actual view was

• 'View with background color specified in Interface Builder': R 0.09 G 0.09 B 0.09 alpha 0.8.
• 'View with background color by code': R 0.07 G 0.07 B 0.07 alpha 0.8

Calculating it,

• 0x12 = 18(decimal)
• 18/255 = 0.07058...
• 255 * 0.09 = 22.95
• 23(decimal) = 0x17

So, I was able to match the colors similarly by setting the UIColor values ??to 17, 17, 17 and alpha 0.8.

self.myFuncView.backgroundColor = UIColor(red: 17, green: 17, blue: 17, alpha: 0.8)

Or can anyone tell me what I'm missing?

The most important consideration is whether the item in question should be able to be traversed more than once. This is because you can always rewind an Iterable by calling iterator() again, but there is no way to rewind an Iterator.

export class Dashboard {
    innerHeight: any;
    innerWidth: any;
    constructor() {
        this.innerHeight = (window.screen.height) + "px";
        this.innerWidth = (window.screen.width) + "px";
    }
}

CLASS METHODS

A class method typically either creates a new instance of the class or retrieves some global properties of the class. Class methods do not operate on an instance or have any access to instance variable.

INSTANCE METHODS

An instance method operates on a particular instance of the class. For example, the accessors method that you implemented are all instance methods. You use them to set or get the instance variables of a particular object.

INVOKE

To invoke an instance method, you send the message to an instance of the class.

To invoke a class method, you send the message to the class directly.

Source: IOS - Objective-C - Class Methods And Instance Methods

You can simply cast to bool, dont forget to handle zero.

function isEmpty(string $string): bool {
    if($string === '0') {
        return false;
    }
    return !(bool)$string;
}

var_dump(isEmpty('')); // bool(true)
var_dump(isEmpty('foo')); // bool(false)
var_dump(isEmpty('0')); // bool(false)

To avoid this warning, instead of using:

parseInt("999", 10);

You may replace it by:

Number("999");

^{Note that parseInt and Number have different behaviors, but in some cases, one can replace the other.}

In case anyone else faces this, it's a case of PHP not having access to the mysql client libraries. Having a MySQL server on the system is not the correct fix. Fix for ubuntu (and PHP 5):

sudo apt-get install php5-mysql

After installing the client, the webserver should be restarted. In case you're using apache, the following should work:

sudo service apache2 restart

As supplementary, if you are reading a vvvvery large file, and you don't want read all of the content into memory at once, you might consider using a buffer, then return each word by yield:

def read_words(inputfile):
    with open(inputfile, 'r') as f:
        while True:
            buf = f.read(10240)
            if not buf:
                break

            # make sure we end on a space (word boundary)
            while not str.isspace(buf[-1]):
                ch = f.read(1)
                if not ch:
                    break
                buf += ch

            words = buf.split()
            for word in words:
                yield word
        yield '' #handle the scene that the file is empty

if __name__ == "__main__":
    for word in read_words('./very_large_file.txt'):
        process(word)

Depending on what you would like to do, you could simply save the variable name, and then access it later on like so:

function toAccessMyVariable(variableName){
  alert(window[variableName]);
}

var myFavoriteNumber = 6; 

toAccessMyVariable("myFavoriteNumber");

To apply to your specific example, you could do something like this:

var x = 0;
var pointerToX = "x";

function a(variableName)
{
    window[variableName]++;
}
a(pointerToX);
alert(x); //Here I want to have 1 instead of 0

For making this r-faq question more complete, a base R alternative with sequence and rle:

df$num <- sequence(rle(df$cat)$lengths)

which gives the intended result:

> df
   cat        val num
4  aaa 0.05638315   1
2  aaa 0.25767250   2
1  aaa 0.30776611   3
5  aaa 0.46854928   4
3  aaa 0.55232243   5
10 bbb 0.17026205   1
8  bbb 0.37032054   2
6  bbb 0.48377074   3
9  bbb 0.54655860   4
7  bbb 0.81240262   5
13 ccc 0.28035384   1
14 ccc 0.39848790   2
11 ccc 0.62499648   3
15 ccc 0.76255108   4
12 ccc 0.88216552   5

If df$cat is a factor variable, you need to wrap it in as.character first:

df$num <- sequence(rle(as.character(df$cat))$lengths)

To get the property of the object or the "array key" or "array index" depending on what your native language is..... Use the Object.keys() method.

Important, this is only compatible with "Modern browsers":

So if your object is called, myObject...

var c = 0;
for(c in myObject) {
    console.log(Object.keys(myObject[c]));
}

Walla! This will definitely work in the latest firefox and ie11 and chrome...

Less no longer evaluates expression inside calc by default since v3.00.

Original answer (Less v1.x...2.x):

Do this:

body { width: calc(~"100% - 250px - 1.5em"); }

In Less 1.4.0 we will have a strictMaths option which requires all Less calculations to be within brackets, so the calc will work "out-of-the-box". This is an option since it is a major breaking change. Early betas of 1.4.0 had this option on by default. The release version has it off by default.

In Rider, this would be Ctrl +Shift+Keypad *, 2

But!, you cannot use the number 2 on keypad, only number 2 on the top row of the keyboard would work.

"^[\w\.\+\-]+\@[\w]+\.[a-z]{2,3}$"

Just create a data.frame with 0 length variables

eg

nodata <- data.frame(x= numeric(0), y= integer(0), z = character(0))
str(nodata)

## 'data.frame':    0 obs. of  3 variables:
##  $ x: num 
##  $ y: int 
##  $ z: Factor w/ 0 levels: 

or to create a data.frame with 5 columns named a,b,c,d,e

nodata <- as.data.frame(setNames(replicate(5,numeric(0), simplify = F), letters[1:5]))

also search for "cannot start eclipse" (I am a new user, I can only post a single hyperlink, so I have to just ask that you search for the second :( sorry)

perhaps those allow you to recover your workspace as well, I hope it helps.

fs.exist() is deprecated. So I have used fs.stat() to check the directory status. If the directory does not exist fs.stat() throw an error with message like 'no such file or directory'. Then I have created a directory.

const fs = require('fs').promises;
    
const dir = './dir';
fs.stat(dir).catch(async (err) => {
  if (err.message.includes('no such file or directory')) {
    await fs.mkdir(dir);
  }
});

Note: these shortcuts only work as expected if you edit your keybindings.json

I wasn't happy with the default shortcuts, I wanted them to work as follow:

• Fold: Ctrl + Alt + ]
• Fold recursively: Ctrl + ? Shift + Alt + ]
• Fold all: Ctrl + k then Ctrl + ]
• Unfold: Ctrl + Alt + [
• Unfold recursively: Ctrl + ? Shift + Alt + [
• Unfold all: Ctrl + k then Ctrl + [

To set it up:

• Open Preferences: Open Keyboard Shortcuts (JSON) (Ctrl + ? Shift + p)
• Add the following snippet to that file

  Already have custom keybindings for fold/unfold? Then you'd need to replace them.

    {
        "key": "ctrl+alt+]",
        "command": "editor.fold",
        "when": "editorTextFocus && foldingEnabled"
    },
    {
        "key": "ctrl+alt+[",
        "command": "editor.unfold",
        "when": "editorTextFocus && foldingEnabled"
    },
    {
        "key": "ctrl+shift+alt+]",
        "command": "editor.foldRecursively",
        "when": "editorTextFocus && foldingEnabled"
    },
    {
        "key": "ctrl+shift+alt+[",
        "command": "editor.unfoldRecursively",
        "when": "editorTextFocus && foldingEnabled"
    },
    {
        "key": "ctrl+k ctrl+[",
        "command": "editor.unfoldAll",
        "when": "editorTextFocus && foldingEnabled"
    },
    {
        "key": "ctrl+k ctrl+]",
        "command": "editor.foldAll",
        "when": "editorTextFocus && foldingEnabled"
    },

The following ways work.

// The old way of using ParameterizedThreadStart. This requires a
// method which takes ONE object as the parameter so you need to
// encapsulate the parameters inside one object.
Thread t = new Thread(new ParameterizedThreadStart(StartupA));
t.Start(new MyThreadParams(path, port));

// You can also use an anonymous delegate to do this.
Thread t2 = new Thread(delegate()
{
    StartupB(port, path);
});
t2.Start();

// Or lambda expressions if you are using C# 3.0
Thread t3 = new Thread(() => StartupB(port, path));
t3.Start();

The Startup methods have following signature for these examples.

public void StartupA(object parameters);

public void StartupB(int port, string path);

I think this answers your question, because it is like a "for each" loop.
The script below is valid in python (version 3.8):

a=[1,7,77,7777,77777,777777,7777777,765,456,345,2342,4]
if (n := len(a)) > 10:
    print(f"List is too long ({n} elements, expected <= 10)")

   data = b.getvalue()

   ip_img = display.Image(data=data, format='png', embed=True)
   return ip_img._repr_png_()


# register display func with PNG formatter:
png_formatter = get_ipython().display_formatter.formatters['image/png']
dpi = png_formatter.for_type(Image.Image, display_pil_image)

After this I can just do:

Assuming you want to simply lift the 32bits from one type and dump them as-is into the other type:

uint asUint = unchecked((uint)myInt);
int asInt = unchecked((int)myUint);

The destination type will blindly pick the 32 bits and reinterpret them.

Conversely if you're more interested in keeping the decimal/numerical values within the range of the destination type itself:

uint asUint = checked((uint)myInt);
int asInt = checked((int)myUint);

In this case, you'll get overflow exceptions if:

• casting a negative int (eg: -1) to an uint
• casting a positive uint between 2,147,483,648 and 4,294,967,295 to an int

In our case, we wanted the unchecked solution to preserve the 32bits as-is, so here are some examples:

Examples

int => uint

------------------------------

Code

int[] testInts = { 0, 1, -1, int.MaxValue, int.MinValue };
uint[] testUints = { uint.MinValue, 1, uint.MaxValue / 2, uint.MaxValue };

foreach (var Int in testInts)
{
    uint asUint = unchecked((uint)Int);
    Console.WriteLine("int....: {0:D10} ({1})", Int, BitConverter.ToString(BitConverter.GetBytes(Int)));
    Console.WriteLine("asUint.: {0:D10} ({1})", asUint, BitConverter.ToString(BitConverter.GetBytes(asUint)));
    Console.WriteLine(new string('-',30));
}
Console.WriteLine(new string('=', 30));
foreach (var Uint in testUints)
{
    int asInt = unchecked((int)Uint);
    Console.WriteLine("uint...: {0:D10} ({1})", Uint, BitConverter.ToString(BitConverter.GetBytes(Uint)));
    Console.WriteLine("asInt..: {0:D10} ({1})", asInt, BitConverter.ToString(BitConverter.GetBytes(asInt)));
    Console.WriteLine(new string('-', 30));
}  

This excerpt from the glibc manual 0.02 may also be relevant when researching the topic:

There is a potential problem with the size_t type and versions of GCC prior to release 2.4. ANSI C requires that size_t always be an unsigned type. For compatibility with existing systems' header files, GCC defines size_t in stddef.h' to be whatever type the system'ssys/types.h' defines it to be. Most Unix systems that define size_t in `sys/types.h', define it to be a signed type. Some code in the library depends on size_t being an unsigned type, and will not work correctly if it is signed.

The GNU C library code which expects size_t to be unsigned is correct. The definition of size_t as a signed type is incorrect. We plan that in version 2.4, GCC will always define size_t as an unsigned type, and the fixincludes' script will massage the system'ssys/types.h' so as not to conflict with this.

In the meantime, we work around this problem by telling GCC explicitly to use an unsigned type for size_t when compiling the GNU C library. `configure' will automatically detect what type GCC uses for size_t arrange to override it if necessary.

I don't see it mentioned here, but splatting your arguments is a useful alternative and becomes especially useful if you are building out the arguments to a command dynamically (as opposed to using Invoke-Expression). You can splat with arrays for positional arguments and hashtables for named arguments. Here are some examples:

Splat With Arrays (Positional Arguments)

Test-Connection with Positional Arguments

Test-Connection www.google.com localhost

With Array Splatting

$argumentArray = 'www.google.com', 'localhost'
Test-Connection @argumentArray

Note that when splatting, we reference the splatted variable with an @ instead of a $. It is the same when using a Hashtable to splat as well.

Splat With Hashtable (Named Arguments)

Test-Connection with Named Arguments

Test-Connection -ComputerName www.google.com -Source localhost

With Hashtable Splatting

$argumentHash = @{
  ComputerName = 'www.google.com'
  Source = 'localhost'
}
Test-Connection @argumentHash

Splat Positional and Named Arguments Simultaneously

Test-Connection With Both Positional and Named Arguments

Test-Connection www.google.com localhost -Count 1

Splatting Array and Hashtables Together

$argumentHash = @{
  Count = 1
}
$argumentArray = 'www.google.com', 'localhost'
Test-Connection @argumentHash @argumentArray

In case than you want to store a complex command to compare text result, for example to compare the version of OS, maybe this can help you:

tasks:
       - shell: echo $(cat /etc/issue | awk {'print $7'})
         register: echo_content

       - shell: echo "It works"
         when: echo_content.stdout == "12"
         register: out
       - debug: var=out.stdout_lines

The b denotes a byte string.

Bytes are the actual data. Strings are an abstraction.

If you had multi-character string object and you took a single character, it would be a string, and it might be more than 1 byte in size depending on encoding.

If took 1 byte with a byte string, you'd get a single 8-bit value from 0-255 and it might not represent a complete character if those characters due to encoding were > 1 byte.

TBH I'd use strings unless I had some specific low level reason to use bytes.

Take the primitive type int for example. There are several ways to declare and int array:

int[] i = new int[capacity];
int[] i = new int[] {value1, value2, value3, etc};
int[] i = {value1, value2, value3, etc};

where in all of these, you can use int i[] instead of int[] i.

With reflection, you can use (Type[]) Array.newInstance(Type.class, capacity);

Note that in method parameters, ... indicates variable arguments. Essentially, any number of parameters is fine. It's easier to explain with code:

public static void varargs(int fixed1, String fixed2, int... varargs) {...}
...
varargs(0, "", 100); // fixed1 = 0, fixed2 = "", varargs = {100}
varargs(0, "", 100, 200); // fixed1 = 0, fixed2 = "", varargs = {100, 200};

Inside the method, varargs is treated as a normal int[]. Type... can only be used in method parameters, so int... i = new int[] {} will not compile.

Note that when passing an int[] to a method (or any other Type[]), you cannot use the third way. In the statement int[] i = *{a, b, c, d, etc}*, the compiler assumes that the {...} means an int[]. But that is because you are declaring a variable. When passing an array to a method, the declaration must either be new Type[capacity] or new Type[] {...}.

Multidimensional Arrays

Multidimensional arrays are much harder to deal with. Essentially, a 2D array is an array of arrays. int[][] means an array of int[]s. The key is that if an int[][] is declared as int[x][y], the maximum index is i[x-1][y-1]. Essentially, a rectangular int[3][5] is:

[0, 0] [1, 0] [2, 0]
[0, 1] [1, 1] [2, 1]
[0, 2] [1, 2] [2, 2]
[0, 3] [1, 3] [2, 3]
[0, 4] [1, 4] [2, 4]

Warning: eval() can be used to execute arbitrary Python code. You should never use eval() with untrusted strings. (See Security of Python's eval() on untrusted strings?)

This seems simplest.

LL(1) grammar is Context free unambiguous grammar which can be parsed by LL(1) parsers.

In LL(1)

• First L stands for scanning input from Left to Right. Second L stands for Left Most Derivation. 1 stands for using one input symbol at each step.

For Checking grammar is LL(1) you can draw predictive parsing table. And if you find any multiple entries in table then you can say grammar is not LL(1).

Their is also short cut to check if the grammar is LL(1) or not . Shortcut Technique

Hey i'm using Volley and was getting Server error 411, I added to the getHeaders method the following line :

And it solved my issue

Make sure the real source file is saved as UTF-8 (You may even want to try the non-recommended BOM Chars with UTF-8 to make sure).

Also in case of HTML, make sure you have declared the correct encoding using meta tags:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

If it's a CMS (as you've tagged your question with Joomla) you may need to configure appropriate settings for the encoding.

It's the only solution to map a ManyToMany association : you need a join table between the two entities tables to map the association.

It's also used for OneToMany (usually unidirectional) associations when you don't want to add a foreign key in the table of the many side and thus keep it independent of the one side.

Search for @JoinTable in the hibernate documentation for explanations and examples.

map doesn't relate to a Cartesian product at all, although I imagine someone well versed in functional programming could come up with some impossible to understand way of generating a one using map.

map in Python 3 is equivalent to this:

def map(func, iterable):
    for i in iterable:
        yield func(i)

and the only difference in Python 2 is that it will build up a full list of results to return all at once instead of yielding.

Although Python convention usually prefers list comprehensions (or generator expressions) to achieve the same result as a call to map, particularly if you're using a lambda expression as the first argument:

[func(i) for i in iterable]

As an example of what you asked for in the comments on the question - "turn a string into an array", by 'array' you probably want either a tuple or a list (both of them behave a little like arrays from other languages) -

 >>> a = "hello, world"
 >>> list(a)
['h', 'e', 'l', 'l', 'o', ',', ' ', 'w', 'o', 'r', 'l', 'd']
>>> tuple(a)
('h', 'e', 'l', 'l', 'o', ',', ' ', 'w', 'o', 'r', 'l', 'd')

A use of map here would be if you start with a list of strings instead of a single string - map can listify all of them individually:

>>> a = ["foo", "bar", "baz"]
>>> list(map(list, a))
[['f', 'o', 'o'], ['b', 'a', 'r'], ['b', 'a', 'z']]

Note that map(list, a) is equivalent in Python 2, but in Python 3 you need the list call if you want to do anything other than feed it into a for loop (or a processing function such as sum that only needs an iterable, and not a sequence). But also note again that a list comprehension is usually preferred:

>>> [list(b) for b in a]
[['f', 'o', 'o'], ['b', 'a', 'r'], ['b', 'a', 'z']]

Escape the percent sign \% to make it part of your comparison value.

A percentage in the value of the font-size property is relative to the parent element’s font size. CSS 2.1 says this obscurely and confusingly (referring to “inherited font size”), but CSS3 Text says it very clearly.

The parent of the body element is the root element, i.e. the html element. Unless set in a style sheet, the font size of the root element is implementation-dependent. It typically depends on user settings.

Setting font-size: 100% is pointless in many cases, as an element inherits its parent’s font size (leading to the same result), if no style sheet sets its own font size. However, it can be useful to override settings in other style sheets (including browser default style sheets).

For example, an input element typically has a setting in browser style sheet, making its default font size smaller than that of copy text. If you wish to make the font size the same, you can set

input { font-size: 100% }

For the body element, the logically redundant setting font-size: 100% is used fairly often, as it is believed to help against some browser bugs (in browsers that probably have lost their significance now).

Update:

The preferences in Settings (Preferences) | Tools | Terminal are global.
If you use a venv for each project, remember to use current path variable and a default venv name:

"cmd.exe" /k ""%CD%\venv\Scripts\activate"" 

For Windows users: when using PyCharm with a virtual environment, you can use the /K parameter to cmd.exe to set the virtual environment automatically.

PyCharm 3 or 4: Settings, Terminal, Default shell and add /K <path-to-your-activate.bat>.

PyCharm 5: Settings, Tools, Terminal, and add /K <path-to-your-activate.bat> to Shell path.

PyCharm 2016.1 or 2016.2: Settings, Tools, Terminal, and add ""/K <path-to-your-activate.bat>"" to Shell path and add (mind the quotes). Also add quotes around cmd.exe, resulting in:

"cmd.exe" /k ""C:\mypath\my-venv\Scripts\activate.bat""

Im not sure if im out of the subject, but i found solution for me; You have a class based view, and you want to have a get parameter as a template tag:

class MyView(DetailView):
    model = MyModel

    def get_context_data(self, **kwargs):
        ctx = super().get_context_data(**kwargs)
        ctx['tag_name'] = self.request.GET.get('get_parameter_name', None)
        return ctx

Then you make your get request /mysite/urlname?get_parameter_name='stuff.

In your template, when you insert {{ tag_name }}, you will have access to the get parameter value ('stuff'). If you have an url in your template that also needs this parameter, you can do

 {% url 'my_url' %}?get_parameter_name={{ tag_name }}"

You will not have to modify your url configuration

For one thing, it says you already have that module installed. If you need to upgrade it, you should do something like this:

easy_install -U packageName

Of course, easy_install doesn't work very well if the package has some C headers that need to be compiled and you don't have the right version of Visual Studio installed. You might try using pip or distribute instead of easy_install and see if they work better.

On your existing button code, simply insert this line before the procedure:

If MsgBox("This will erase everything! Are you sure?", vbYesNo) = vbNo Then Exit Sub

This will force it to quit if the user presses no.

Applying the input-block-level class works great for me, across various screen widths. It is defined by Bootstrap in mixins.less as follows:

// Block level inputs
.input-block-level {
  display: block;
  width: 100%;
  min-height: 28px;        // Make inputs at least the height of their button counterpart
  .box-sizing(border-box); // Makes inputs behave like true block-level elements
}

This is very similar to the style suggested by 'assembler' in his comment on issue #1058.

I required a specific colour, so filter didn't work for me.

Instead, I created a div, exploiting CSS multiple background images and the linear-gradient function (which creates an image itself). If you use the overlay blend mode, your actual image will be blended with the generated "gradient" image containing your desired colour (here, #BADA55)

.colored-image {_x000D_
        background-image: linear-gradient(to right, #BADA55, #BADA55), url("https://i.imgur.com/lYXT8R6.png");_x000D_
        background-blend-mode: overlay;_x000D_
        background-size: contain;_x000D_
        width: 200px;_x000D_
        height: 200px;        _x000D_
    }

<div class="colored-image"></div>

No -P needed; -E is sufficient:

grep -E '(^|\s)abc(\s|$)' 

or even without -E:

grep '\(^\|\s\)abc\(\s\|$\)' 

See the fiddle demo to create a table from an array.

function createTable(tableData) {
  var table = document.createElement('table');
  var row = {};
  var cell = {};

  tableData.forEach(function(rowData) {
    row = table.insertRow(-1); // [-1] for last position in Safari
    rowData.forEach(function(cellData) {
      cell = row.insertCell();
      cell.textContent = cellData;
    });
  });
  document.body.appendChild(table);
}

You can use it like this

var tableData = [["r1c1", "r1c2"], ["r2c1", "r2c2"], ["r3c1", "r3c2"]];
createTable(tableData);

I had played a bit with super(), and had recognized that we can change calling order.

For example, we have next hierarchy structure:

    A
   / \
  B   C
   \ /
    D

In this case MRO of D will be (only for Python 3):

In [26]: D.__mro__
Out[26]: (__main__.D, __main__.B, __main__.C, __main__.A, object)

Let's create a class where super() calls after method execution.

In [23]: class A(object): #  or with Python 3 can define class A:
...:     def __init__(self):
...:         print("I'm from A")
...:  
...: class B(A):
...:      def __init__(self):
...:          print("I'm from B")
...:          super().__init__()
...:   
...: class C(A):
...:      def __init__(self):
...:          print("I'm from C")
...:          super().__init__()
...:  
...: class D(B, C):
...:      def __init__(self):
...:          print("I'm from D")
...:          super().__init__()
...: d = D()
...:
I'm from D
I'm from B
I'm from C
I'm from A

    A
   / ?
  B ? C
   ? /
    D

So we can see that resolution order is same as in MRO. But when we call super() in the beginning of the method:

In [21]: class A(object):  # or class A:
...:     def __init__(self):
...:         print("I'm from A")
...:  
...: class B(A):
...:      def __init__(self):
...:          super().__init__()  # or super(B, self).__init_()
...:          print("I'm from B")
...:   
...: class C(A):
...:      def __init__(self):
...:          super().__init__()
...:          print("I'm from C")
...:  
...: class D(B, C):
...:      def __init__(self):
...:          super().__init__()
...:          print("I'm from D")
...: d = D()
...: 
I'm from A
I'm from C
I'm from B
I'm from D

We have a different order it is reversed a order of the MRO tuple.

    A
   / ?
  B ? C
   ? /
    D

Assign variable to the blade template, Here are the solutions

We can use <?php ?> tag in blade page

<?php $var = 'test'; ?>
{{ $var }

OR

We can use the blade comment with special syntax

{{--*/ $var = 'test' /*--}}
{{ $var }}

You can combine the best method into one line or function, and have the new query auto-generated for you:

function getRowCount($q){ 
    global $db;
    return $db->query(preg_replace('/SELECT [A-Za-z,]+ FROM /i','SELECT count(*) FROM ',$q))->fetchColumn();
}

$numRows = getRowCount($query);

You can construct a pivot table for each distinct value of X. In this case,

for xval, xgroup in g:
    ptable = pd.pivot_table(xgroup, rows='Y', cols='Z', 
        margins=False, aggfunc=numpy.size)

will construct a pivot table for each value of X. You may want to index ptable using the xvalue. With this code, I get (for X1)

     X        
Z   Z1  Z2  Z3
Y             
Y1   2   1 NaN
Y2 NaN NaN   1

Check out CORS enabled image from MDN. Basically you must have a server hosting images with the appropriate Access-Control-Allow-Origin header.

<IfModule mod_setenvif.c>
    <IfModule mod_headers.c>
        <FilesMatch "\.(cur|gif|ico|jpe?g|png|svgz?|webp)$">
            SetEnvIf Origin ":" IS_CORS
            Header set Access-Control-Allow-Origin "*" env=IS_CORS
        </FilesMatch>
    </IfModule>
</IfModule>

You will be able to save those images to DOM Storage as if they were served from your domain otherwise you will run into security issue.

var img = new Image,
    canvas = document.createElement("canvas"),
    ctx = canvas.getContext("2d"),
    src = "http://example.com/image"; // insert image url here

img.crossOrigin = "Anonymous";

img.onload = function() {
    canvas.width = img.width;
    canvas.height = img.height;
    ctx.drawImage( img, 0, 0 );
    localStorage.setItem( "savedImageData", canvas.toDataURL("image/png") );
}
img.src = src;
// make sure the load event fires for cached images too
if ( img.complete || img.complete === undefined ) {
    img.src = "data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///ywAAAAAAQABAAACAUwAOw==";
    img.src = src;
}

I too felt like the accepted answer was a bit misleading as it could lead to a user inadvertently deleting multiple Projects. It is not accurate to state that the words Repository, Project and Directory are ambiguous within the context of SVN. They have specific meanings, even if the system itself doesn't enforce those meanings. The community and more importantly the SVN Clients have an agreed upon understanding of these terms which allow them to Tag, Branch and Merge.

Ideally this will help clear any confusion. As someone that has had to go from git to svn for a few projects, it can be frustrating until you learn that SVN branching and SVN projects are really talking about folder structures.

SVN Terminology

Repository

The database of commits and history for your folders and files. A repository can contain multiple 'projects' or no projects.

Project

A specific SVN folder structure which enables SVN tools to perform tagging, merging and branching. SVN does not inherently support branching. Branching was added later and is a result of a special folder structure as follows:

• /project
  • /tags
  • /branches
  • /trunk

Note: Remember, an SVN 'Project' is a term used to define a specific folder strcuture within a Repository

Projects in a Repository

Repository Layout

• http://svn.server.local/svn/myrepo

  • /skunkworks "Project" due to layout
    • /tags
    • /branches
    • /trunk
  • /app1 "Project" due to layout
    • /tags
    • /branches
    • /trunk
  • /fooproject "Project" due to layout
    • /tags
    • /branches
    • /trunk
  • /regulardir <-- Not a "Project"
    • /subdir

• http://svn.server.local/svn/myrepo2

  • /app2"Project" due to layout
    • /tags
    • /branches
    • /trunk

As a repository is just a database of the files and directory commits, it can host multiple projects. When discussing Repositories and Projects be sure the correct term is being used.

Removing a Repository could mean removing multiple Projects!

Local SVN Directory (.svn directory at root)

When using a URL commits occur automatically.

• svn co http://svn.server.local/svn/myrepo

• cd myrepo

• Remove a Project: svn rm skunkworks + svn commit

• Remove a Directory: svn rm regulardir/subdir + svn commit
• Remove a Project (Without Checking Out): svn rm http://svn.server.local/svn/myrepo/app1
• Remove a Directory (Without Checking Out): svn rm http://svn.server.local/svn/myrepo/regulardir

Because an SVN Project is really a specific directory structure, removing a project is the same as removing a directory.

SVN Repository Management

There are several SVN servers available to host your repositories. The management of repositories themselves are typically done through the admin consoles of the servers. For example, Visual SVN allows you to create Repositories (databases), directories and Projects. But you cannot remove files, manage commits, rename folders, etc. from within the server console as those are SVN specific tasks. The SVN server typically manages the creation of a repository. Once a repository has been created and you have a new URL, the rest of your work is done through the svn command.

If there are no formats in the string, you can use puts (or fputs):

puts("hello%");

if there is a format in the string:

printf("%.2f%%", 53.2);

As noted in the comments, puts appends a \n to the output and fputs does not.

The simplest way would be to convert your hexadecimal string to a byte array and use the File.WriteAllBytes method.

Using the StringToByteArray() method from this question, you'd do something like this:

string hexString = "0CFE9E69271557822FE715A8B3E564BE";

File.WriteAllBytes("output.dat", StringToByteArray(hexString));

The StringToByteArray method is included below:

public static byte[] StringToByteArray(string hex) {
    return Enumerable.Range(0, hex.Length)
                     .Where(x => x % 2 == 0)
                     .Select(x => Convert.ToByte(hex.Substring(x, 2), 16))
                     .ToArray();
}

Either You can use LinkedHashMap<K, V> or you can implement you own CustomMap which maintains insertion order.

You can use the Following CustomHashMap with the following features:

• Insertion order is maintained, by using LinkedHashMap internally.
• Keys with null or empty strings are not allowed.
• Once key with value is created, we are not overriding its value.

HashMap vs LinkedHashMap vs CustomHashMap

interface CustomMap<K, V> extends Map<K, V> {
    public boolean insertionRule(K key, V value);
}

@SuppressWarnings({ "rawtypes", "unchecked" })
public class CustomHashMap<K, V> implements CustomMap<K, V> {
    private Map<K, V> entryMap;
    // SET: Adds the specified element to this set if it is not already present.
    private Set<K> entrySet;

    public CustomHashMap() {
        super();
        entryMap = new LinkedHashMap<K, V>();
        entrySet = new HashSet();
    }

    @Override
    public boolean insertionRule(K key, V value) {
        // KEY as null and EMPTY String is not allowed.
        if (key == null || (key instanceof String && ((String) key).trim().equals("") ) ) {
            return false;
        }

        // If key already available then, we are not overriding its value.
        if (entrySet.contains(key)) { // Then override its value, but we are not allowing
            return false;
        } else { // Add the entry
            entrySet.add(key);
            entryMap.put(key, value);
            return true;
        }
    }
    public V put(K key, V value) {
        V oldValue = entryMap.get(key);
        insertionRule(key, value);
        return oldValue;
    }
    public void putAll(Map<? extends K, ? extends V> t) {
        for (Iterator i = t.keySet().iterator(); i.hasNext();) {
            K key = (K) i.next();
            insertionRule(key, t.get(key));
        }
    }

    public void clear() {
        entryMap.clear();
        entrySet.clear();
    }
    public boolean containsKey(Object key) {
        return entryMap.containsKey(key);
    }
    public boolean containsValue(Object value) {
        return entryMap.containsValue(value);
    }
    public Set entrySet() {
        return entryMap.entrySet();
    }
    public boolean equals(Object o) {
        return entryMap.equals(o);
    }
    public V get(Object key) {
        return entryMap.get(key);
    }
    public int hashCode() {
        return entryMap.hashCode();
    }
    public boolean isEmpty() {
        return entryMap.isEmpty();
    }
    public Set keySet() {
        return entrySet;
    }
    public V remove(Object key) {
        entrySet.remove(key);
        return entryMap.remove(key);
    }
    public int size() {
        return entryMap.size();
    }
    public Collection values() {
        return entryMap.values();
    }
}

Usage of CustomHashMap:

public static void main(String[] args) {
    System.out.println("== LinkedHashMap ==");
    Map<Object, String> map2 = new LinkedHashMap<Object, String>();
    addData(map2);

    System.out.println("== CustomHashMap ==");
    Map<Object, String> map = new CustomHashMap<Object, String>();
    addData(map);
}
public static void addData(Map<Object, String> map) {
    map.put(null, "1");
    map.put("name", "Yash");
    map.put("1", "1 - Str");
    map.put("1", "2 - Str"); // Overriding value
    map.put("", "1"); // Empty String
    map.put(" ", "1"); // Empty String
    map.put(1, "Int");
    map.put(null, "2"); // Null

    for (Map.Entry<Object, String> entry : map.entrySet()) {
        System.out.println(entry.getKey() + " = " + entry.getValue());
    }
}

O/P:

== LinkedHashMap == | == CustomHashMap ==
null = 2            | name = Yash
name = Yash         | 1 = 1 - Str
1 = 2 - Str         | 1 = Int
 = 1                |
  = 1               |
1 = Int             |

If you know the KEY's are fixed then you can use EnumMap. Get the values form Properties/XML files

EX:

enum ORACLE {
    IP, URL, USER_NAME, PASSWORD, DB_Name;
}

EnumMap<ORACLE, String> props = new EnumMap<ORACLE, String>(ORACLE.class);
props.put(ORACLE.IP, "127.0.0.1");
props.put(ORACLE.URL, "...");
props.put(ORACLE.USER_NAME, "Scott");
props.put(ORACLE.PASSWORD, "Tiget");
props.put(ORACLE.DB_Name, "MyDB");

On the formula menu just Select "Default Values for Nulls" then just add all the fields like the below:

{@Table.Field1} + {@Table.Field2} + {@Table.Field3} + {@Table.Field4} + {@Table.Field5}

The accepted answer is faulty, since the contents from the initial user folder are not moved using it. I am going to add another answer to correct it:

sudo usermod -d /newhome/username -m username

You don't need to create the folder with username and this will also move your files from the initial user folder to /newhome/username folder.

Create a public integer in the General Declaration.

Then in your function you can increase its value each time. See example (function to save attachements of an email as CSV).

Public Numerator As Integer

Public Sub saveAttachtoDisk(itm As Outlook.MailItem)
Dim objAtt As Outlook.Attachment
Dim saveFolder As String
Dim FileName As String

saveFolder = "c:\temp\"

     For Each objAtt In itm.Attachments
            FileName = objAtt.DisplayName & "_" & Numerator & "_" & Format(Now, "yyyy-mm-dd H-mm-ss") & ".CSV"
                      objAtt.SaveAsFile saveFolder & "\" & FileName
                      Numerator = Numerator + 1

          Set objAtt = Nothing
     Next
End Sub

VBScript doesn't have Try/Catch. (VBScript language reference. If it had Try, it would be listed in the Statements section.)

On Error Resume Next is the only error handling in VBScript. Sorry. If you want try/catch, JScript is an option. It's supported everywhere that VBScript is and has the same capabilities.

An xmlns is a unique identifier within the document - it doesn't have to be a URI to the schema:

XML namespaces provide a simple method for qualifying element and attribute names used in Extensible Markup Language documents by associating them with namespaces identified by URI references.

xsi:schemaLocation is supposed to give a hint as to the actual schema location:

can be used in a document to provide hints as to the physical location of schema documents which may be used for assessment.

Pretty much the same way that you always have, with "Modules" instead of classes and just use "Public" instead of the old "Global" keyword:

Public Module Module1
    Public Foo As Integer
End Module

Using btoa with unescape and encodeURIComponent didn't work for me. Replacing all the special characters with XML/HTML entities and then converting to the base64 representation was the only way to solve this issue for me. Some code:

base64 = btoa(str.replace(/[\u00A0-\u2666]/g, function(c) {
    return '&#' + c.charCodeAt(0) + ';';
}));
