This how you can do it.

const date = new Date();_x000D_
const time = date.toTimeString().split(' ')[0].split(':');_x000D_
console.log(time[0] + ':' + time[1])

Below code works fine before 18 API :-

public String getRealPathFromURI(Uri contentUri) {

        // can post image
        String [] proj={MediaStore.Images.Media.DATA};
        Cursor cursor = managedQuery( contentUri,
                        proj, // Which columns to return
                        null,       // WHERE clause; which rows to return (all rows)
                        null,       // WHERE clause selection arguments (none)
                        null); // Order-by clause (ascending by name)
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();

        return cursor.getString(column_index);
}

below code use on kitkat :-

public static String getPath(final Context context, final Uri uri) {

    // DocumentProvider
    if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {

I read & tried All Fixes But Not one worked. At last i Found that the Wamp Server Logo Is Green But Need to Be "PUT ONLINE". So simple & a Quick Fix After Checking Your PHPMyAdmin.Cofg & HttPD.cofg Just Click on PUT ONLINE

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

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

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

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

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

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

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

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

            root.appendChild(newServer);
        }

        DOMSource source = new DOMSource(document);

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

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

Example server.xml file:

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

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

I created a web site https://www.swdoc.org/ that specifically addresses the problem. So it automates swagger.json -> Asciidoc, Asciidoc -> pdf transformation as suggested in the answers. Benefit of this is that you dont need to go through the installation procedures. It accepts a spec document in form of url or just a raw json. Project is written in C# and its page is https://github.com/Irdis/SwDoc

EDIT

It might be a good idea to validate your json specs here: http://editor.swagger.io/ if you are having any problems with SwDoc, like the pdf being generated incomplete.

There is a javascript library for this, see FileSaver.js on Github

However the saveAs() function won't send pure string to the browser, you need to convert it to blob:

function data2blob(data, isBase64) {
  var chars = "";

  if (isBase64)
    chars = atob(data);
  else
    chars = data;

  var bytes = new Array(chars.length);
  for (var i = 0; i < chars.length; i++) {
    bytes[i] = chars.charCodeAt(i);
  }

  var blob = new Blob([new Uint8Array(bytes)]);
  return blob;
}

and then call saveAs on the blob, as like:

var myString = "my string with some stuff";
saveAs( data2blob(myString), "myString.txt" );

Of course remember to include the above-mentioned javascript library on your webpage using <script src=FileSaver.js>

Something along the lines of:

yourString = yourString.replace ( /[^0-9]/g, '' );

the best way is -
1) Sort the both array which are used in first and second loop.
2) if item matched then break the inner loop and hold the index value.
3) when start next iteration start inner loop with hold index value.

There should be three pages here:

1. Initial login page with a form that asks for your username, but not your password.
2. You didn't mention this one, but I'd check whether the client computer is recognized, and if not, then challenge the user with either a CAPTCHA or else a security question. Otherwise the phishing site can simply use the tendered username to query the real site for the security image, which defeats the purpose of having a security image. (A security question is probably better here since with a CAPTCHA the attacker could have humans sitting there answering the CAPTCHAs to get at the security images. Depends how paranoid you want to be.)
3. A page after that that displays the security image and asks for the password.

I don't see this short, linear flow being sufficiently complex to warrant using Spring Web Flow.

I would just use straight Spring Web MVC for steps 1 and 2. I wouldn't use Spring Security for the initial login form, because Spring Security's login form expects a password and a login processing URL. Similarly, Spring Security doesn't provide special support for CAPTCHAs or security questions, so you can just use Spring Web MVC once again.

You can handle step 3 using Spring Security, since now you have a username and a password. The form login page should display the security image, and it should include the user-provided username as a hidden form field to make Spring Security happy when the user submits the login form. The only way to get to step 3 is to have a successful POST submission on step 1 (and 2 if applicable).

From Swift 5.3, you do not have to unwrap self in closure if you pass [self] before in in closure.

Refer someFunctionWithEscapingClosure { [self] in x = 100 } in this swift doc

 var filterTransNos = (from so in db.SalesOrderDetails
                    where  ItemDescription.Contains(ItemDescription)
                            select new { so.TransNo }).AsEnumerable();    


listreceipt = listreceipt.Where(p => filterTransNos.Any(p2 => p2.TransNo == p.TransNo)).ToList();

I had the same situation where three devices connected to one same host but only one had 'no permissions' others were online.

Adding SUID or SGID on adb was another issue for me. Devices seen offline every time adb restarts - until you acknowledge on the devices every time.

I solved this 'no permissions' issue by adding 'o+w' permission for a device file.

chmod o+w /dev/bus/usb/00n/xxx

You just need to specify the Position column to be an ordered factor where the levels are ordered by their counts:

theTable <- transform( theTable,
       Position = ordered(Position, levels = names( sort(-table(Position)))))

(Note that the table(Position) produces a frequency-count of the Position column.)

Then your ggplot function will show the bars in decreasing order of count. I don't know if there's an option in geom_bar to do this without having to explicitly create an ordered factor.

Is this what you're looking for?

When you don’t have stable IDs for rendered items, you may use the item index as a key as a last resort:

const todoItems = todos.map((todo, index) =>
// Only do this if items have no stable IDs
   <li key={index}>
      {todo.text}
   </li>
);

The color plugin is only 4kb so much cheaper than the UI library. Of course you'll want to use a decent version of the plugin and not some buggy old thing which doesn't handle Safari and crashes when the transitions are too fast. Since a minified version isn't supplied you might like test various compressors and make your own min version. YUI gets the best compression in this case needing only 2317 bytes and since it is so small - here it is:

To update and answer the question without breaking mail servers. Later versions of CentOS 7 have MariaDB included as the base along with PostFix which relies on MariaDB. Removing using yum will also remove postfix and perl-DBD-MySQL. To get around this and keep postfix in place, first make a copy of /usr/lib64/libmysqlclient.so.18 (which is what postfix depends on) and then use:

rpm -qa | grep mariadb

then remove the mariadb packages using (changing to your versions):

rpm -e --nodeps "mariadb-libs-5.5.56-2.el7.x86_64"
rpm -e --nodeps "mariadb-server-5.5.56-2.el7.x86_64"
rpm -e --nodeps "mariadb-5.5.56-2.el7.x86_64"

Delete left over files and folders (which also removes any databases):

rm -f /var/log/mariadb
rm -f /var/log/mariadb/mariadb.log.rpmsave
rm -rf /var/lib/mysql
rm -rf /usr/lib64/mysql
rm -rf /usr/share/mysql

Put back the copy of /usr/lib64/libmysqlclient.so.18 you made at the start and you can restart postfix.

There is more detail at https://code.trev.id.au/centos-7-remove-mariadb-replace-mysql/ which describes how to replace mariaDB with MySQL

Rumble supports JSON natively with JSONiq and runs on Spark, managing DataFrames internally so you don't need to -- even if the data isn't fully structured:

let $coords := "42.974049,-81.205203%7C42.974298,-81.195755"
let $request := json-doc("http://maps.googleapis.com/maps/api/elevation/json?locations="||$coords||"&sensor=false")
for $obj in $request.results[]
return {
  "latitude" : $obj.location.lat,
  "longitude" : $obj.location.lng,
  "elevation" : $obj.elevation
}

The results can be exported to CSV and then reopened in any other host language as a DataFrame.

You can use an overlay with opacity set in order to the buttons/anchors in the back stay visible, but once you have that overlay over an element, you can't click it.

This is what worked for me:

.pdf::before {
    content: url('path/to/image.png');
    display: flex;
    align-items: center;
    justify-content: center;
    height: inherit;
}

It might be worth noting that this can also occur when Windows blocks downloads that it considers to be unsafe. This can be addressed by right-clicking the jar file (such as ojdbc7.jar), and checking the 'Unblock' box at the bottom.

Windows JAR File Properties Dialog:

export PGPASSWORD=<password>
psql -h <host> -d <database> -U <user_name> -p <port> -a -w -f <file>.sql

One liner and IE11 friendly:

> (window.location.href).match('c=([^&]*)')[1]
> "m2-m3-m4-m5"

HTML 5 allows summary tag, details element. That can be used to view or hide (collapse/expand) a section. Link

Use sprintf():

int someInt = 368;
char str[12];
sprintf(str, "%d", someInt);

All numbers that are representable by int will fit in a 12-char-array without overflow, unless your compiler is somehow using more than 32-bits for int. When using numbers with greater bitsize, e.g. long with most 64-bit compilers, you need to increase the array size—at least 21 characters for 64-bit types.

The exponential function is e^x where e is a mathematical constant called Euler's number, approximately 2.718281. This value has a close mathematical relationship with pi and the slope of the curve e^x is equal to its value at every point. np.exp() calculates e^x for each value of x in your input array.

To run function onLoad

jQuery(window).on("load", function(){
    ..code..
});

To run code onDOMContentLoaded (also called onready)

jQuery(document).ready(function(){
    ..code..
});

or the recommended shorthand for onready

jQuery(function($){
    ..code.. ($ is the jQuery object)
});

onready fires when the document has loaded

onload fires when the document and all the associated content, like the images on the page have loaded.

Here is a one liner. A little improvised answer using format with print() to iterate a list.

How about this (python 3.x):

sample_list = ['cat', 'dog', 'bunny', 'pig']
print("Your list of animals are: {}, {}, {} and {}".format(*sample_list))

Read the docs here on using format().

I'm not sure if this will work for your actual use, but it works in your test case - updated at http://jsfiddle.net/sTD8y/27/ .

I just made it so that the built-in revert is only used if the item has not been dropped before. If it has been dropped, the revert is done manually. You could adjust this to animate to some calculated offset by checking the actual CSS properties, but I'll let you play with that because a lot of it depends on the CSS of the draggable and it's surrounding DOM structure.

$(function() {
    $("#draggable").draggable({
        revert:  function(dropped) {
             var $draggable = $(this),
                 hasBeenDroppedBefore = $draggable.data('hasBeenDropped'),
                 wasJustDropped = dropped && dropped[0].id == "droppable";
             if(wasJustDropped) {
                 // don't revert, it's in the droppable
                 return false;
             } else {
                 if (hasBeenDroppedBefore) {
                     // don't rely on the built in revert, do it yourself
                     $draggable.animate({ top: 0, left: 0 }, 'slow');
                     return false;
                 } else {
                     // just let the built in revert work, although really, you could animate to 0,0 here as well
                     return true;
                 }
             }
        }
    });

    $("#droppable").droppable({
        activeClass: 'ui-state-hover',
        hoverClass: 'ui-state-active',
        drop: function(event, ui) {
            $(this).addClass('ui-state-highlight').find('p').html('Dropped!');
            $(ui.draggable).data('hasBeenDropped', true);
        }
    });
});

I do have an article on MSDN - Creating ASP.NET MVC with custom bootstrap theme / layout using VS 2012, VS 2013 and VS 2015, also have a demo code sample attached.. Please refer below link. https://code.msdn.microsoft.com/ASPNET-MVC-application-62ffc106

For my case, I have a dropdown list in my div container, so I can not use overflow: hidden or my dropdown list will be hidden.

Inspired by this discussion: https://twitter.com/siddharthkp/status/1094821277452234752 I use border-bottom-left-radius and border-bottom-right-radius in the child element to fix this issue.

make sure you add it the correct value for each child separately

Use

weightMatrix = []
for k in range(motifWidth):
    weightMatrix.append({'A':0,'C':0,'G':0,'T':0})

Thanks, that helped me. I made some improvements and wrapped that in a helper script "finalurl":

#!/bin/bash
curl $1 -s -L -I -o /dev/null -w '%{url_effective}'

• -o output to /dev/null
• -I don't actually download, just discover the final URL
• -s silent mode, no progressbars

This made it possible to call the command from other scripts like this:

echo `finalurl http://someurl/`

 var result = _context.Employees
                .Where(x => !x.IsDeleted)
                .Where(x => x.ClientId > (clientId > 0 ? clientId - 1 : -1))
                .Where(x => x.ClientId < (clientId > 0 ? clientId + 1 : 1000))
                .Where(x => x.ContractorFlag == employeeFlag);
            return result;

If clientId = 0 we want ALL employees,. but for any clientId between 1 and 999 we want only clients with that ID. I was having issues with seperate LINQ statements not being the same (Deleted/Clients filters need to be on all queries), so by add these two lines it works (all be it until we have 999+ clients - which would be a happy re-factor day!!

Might the UNION operator work for you? Have one SELECT for each section, then UNION them together. Guess it would only work for a fixed number of sections though.

A unique approach would be to reverse the array and then loop. This will work for non-numerically indexed arrays as well:

$items = array(
    'one'   => 'two',
    'two'   => 'two',
    'three' => 'three'
);
$backwards = array_reverse($items);
$last_item = NULL;

foreach ($backwards as $current_item) {
    if ($last_item === $current_item) {
        // they match
    }
    $last_item = $current_item;
}

If you are still interested in using the current and next functions, you could do this:

$items = array('two', 'two', 'three');
$length = count($items);
for($i = 0; $i < $length - 1; ++$i) {
    if (current($items) === next($items)) {
        // they match
    }
}

#2 is probably the best solution. Note, $i < $length - 1; will stop the loop after comparing the last two items in the array. I put this in the loop to be explicit with the example. You should probably just calculate $length = count($items) - 1;

Using map and lambda function can produce a list of hex values, which can be printed (or used for other purposes)

>>> s = 'Hello 1 2 3 \x01\x02\x03 :)'

>>> map(lambda c: hex(ord(c)), s)
['0x48', '0x65', '0x6c', '0x6c', '0x6f', '0x20', '0x31', '0x20', '0x32', '0x20', '0x33', '0x20', '0x1', '0x2', '0x3', '0x20', '0x3a', '0x29']

Though you can do this through PHP's time functions, let me introduce you to PHP's DateTime class, which along with it's related classes, really should be in any PHP developer's toolkit.

// note this will set to today's current date since you are not specifying it in your passed parameter. This probably doesn't matter if you are just going to add time to it.
$datetime = DateTime::createFromFormat('g:i:s', $selectedTime);
$datetime->modify('+15 minutes');
echo $datetime->format('g:i:s');

Note that if what you are looking to do is basically provide a 12 or 24 hours clock functionality to which you can add/subtract time and don't actually care about the date, so you want to eliminate possible problems around daylights saving times changes an such I would recommend one of the following formats:

!g:i:s 12-hour format without leading zeroes on hour

!G:i:s 12-hour format with leading zeroes

Note the ! item in format. This would set date component to first day in Linux epoch (1-1-1970)

Actually you can pass a parameter ( http://docs.angularjs.org/api/ng.filter:filter ) and don't need a custom function just for this. If you rewrite your HTML as below it'll work:

<div ng:app>
 <div ng-controller="HelloCntl">
 <ul>
    <li ng-repeat="friend in friends | filter:{name:'!Adam'}">
        <span>{{friend.name}}</span>
        <span>{{friend.phone}}</span>
    </li>
 </ul>
 </div>
</div>

Same issue. I solved setting the "skip install" flag to YES for each external projects, leaving the other targets of the main project unchanged.

I also had to go to "Edit scheme…", choose the "Archiving" panel and set the correct build setting for my ad-hoc purpose.

Then a simple Product -> Archive -> Share made the expected job.

To use vertical-align properly, you should do it on table tag. But there is a way to make other html tags to behave as a table by assigning them a css of display:table to your parent, and display:table-cell on your child. Then vertical-align:bottom will work on that child.

HTML:

??????<div class="parent">
    <div class="child">
        This text is vertically aligned to bottom.    
    </div>
</div>????????????????????????

CSS:

?.parent {
    width: 300px;
    height: 50px;
    display:? table;
    border: 1px solid red;
}
.child { 
    display: table-cell;
    vertical-align: bottom;
}?

You can use the he library, available from https://github.com/mathiasbynens/he

Example:

console.log(he.decode("Jörg &amp Jürgen rocked to & fro "));
// Logs "Jörg & Jürgen rocked to & fro"

I challenged the library's author on the question of whether there was any reason to use this library in clientside code in favour of the <textarea> hack provided in other answers here and elsewhere. He provided a few possible justifications:

• If you're using node.js serverside, using a library for HTML encoding/decoding gives you a single solution that works both clientside and serverside.

• Some browsers' entity decoding algorithms have bugs or are missing support for some named character references. For example, Internet Explorer will both decode and render non-breaking spaces ( ) correctly but report them as ordinary spaces instead of non-breaking ones via a DOM element's innerText property, breaking the <textarea> hack (albeit only in a minor way). Additionally, IE 8 and 9 simply don't support any of the new named character references added in HTML 5. The author of he also hosts a test of named character reference support at http://mathias.html5.org/tests/html/named-character-references/. In IE 8, it reports over one thousand errors.

  If you want to be insulated from browser bugs related to entity decoding and/or be able to handle the full range of named character references, you can't get away with the <textarea> hack; you'll need a library like he.

• He just darn well feels like doing things this way is less hacky.

document.ondomcontentready=function(){} should do the trick, but it doesn't have full browser compatibility.

Seems like you should just use jQuery min

I recommend IdentityServer.This is a .NET Foundation project and covers many issues about authentication and authorization.

Overview

IdentityServer is a .NET/Katana-based framework and hostable component that allows implementing single sign-on and access control for modern web applications and APIs using protocols like OpenID Connect and OAuth2. It supports a wide range of clients like mobile, web, SPAs and desktop applications and is extensible to allow integration in new and existing architectures.

For more information, e.g.

• support for MembershipReboot and ASP.NET Identity based user stores
• support for additional Katana authentication middleware (e.g. Google, Twitter, Facebook etc)
• support for EntityFramework based persistence of configuration
• support for WS-Federation
• extensibility

check out the documentation and the demo.

An alternative: you can use a "hidden" applet element which implements this exist-check using a privileged action object and override your run method by:

File file = new File(yourPath);
return file.exists();

// logout

if(isset($_GET['logout'])) {
    session_destroy();
    unset($_SESSION['username']);
    header('location:login.php');
}

?>

I think you used the brackets the wrong way. Try this:

$test = (empty($address['street2']) ? 'Yes <br />' : 'No <br />');

I think it should work, you can also use:

echo (empty($address['street2']) ? 'Yes <br />' : 'No <br />');

I think it is so it can keep consistency with the available options used when settings multiple css styles in one function call through the use of an object, for example...

$(".element").css( { marginLeft : "200px", marginRight : "200px" } );

as you can see the property are not specified as strings. JQuery also supports using string if you still wanted to use the dash, or for properties that perhaps cannot be set without the dash, so the following still works...

$(".element").css( { "margin-left" : "200px", "margin-right" : "200px" } );

without the quotes here, the javascript would not parse correctly as property names cannot have a dash in them.

EDIT: It would appear that JQuery is not actually making the distinction itsleft, instead it is just passing the property specified for the DOM to care about, most likely with style[propertyName];

There is a much simpler way to do it (git 1.7.6+):

git status --ignored

See Is there a way to tell git-status to ignore the effects of .gitignore files?

MySQL will also report "Column count doesn't match value count at row 1" if you try to insert multiple rows without delimiting the row sets in the VALUES section with parentheses, like so:

INSERT INTO `receiving_table`
  (id,
  first_name,
  last_name)
VALUES 
  (1002,'Charles','Babbage'),
  (1003,'George', 'Boole'),
  (1001,'Donald','Chamberlin'),
  (1004,'Alan','Turing'),
  (1005,'My','Widenius');

Using MAMP ON Mac, I solve my problem by renaming

Create an Extension Method most likely you will want to use this more than once and this prevents duplicate code.

Implementation:

 public static void AddRange<T, S>(this Dictionary<T, S> source, Dictionary<T, S> collection)
 {
        if (collection == null)
        {
            throw new ArgumentNullException("Collection is null");
        }

        foreach (var item in collection)
        {
            if(!source.ContainsKey(item.Key)){ 
               source.Add(item.Key, item.Value);
            }
            else
            {
               // handle duplicate key issue here
            }  
        } 
 }

Usage:

Dictionary<string,string> animals = new Dictionary<string,string>();
Dictionary<string,string> newanimals = new Dictionary<string,string>();

animals.AddRange(newanimals);

Yes, you can do the same in Seaborn directly. This is done with tsplot() which allows either a single array as input, or two arrays where the other is 'time' i.e. x-axis.

import seaborn as sns

data =  [1,5,3,2,6] * 20
time = range(100)

sns.tsplot(data, time)

// you need to have a list of data that you want the spinner to display
List<String> spinnerArray =  new ArrayList<String>();
spinnerArray.add("item1");
spinnerArray.add("item2");

ArrayAdapter<String> adapter = new ArrayAdapter<String>(
    this, android.R.layout.simple_spinner_item, spinnerArray);

adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
Spinner sItems = (Spinner) findViewById(R.id.spinner1);
sItems.setAdapter(adapter);

also to find out what is selected you could do something like this

String selected = sItems.getSelectedItem().toString();
if (selected.equals("what ever the option was")) {
}

Apparently the free NetDrive software from Novell can access SFTP file servers.

I want to create a kind of stopwatch that when minutes reach 20 minutes, brings up a dialog box.

All you need is to sleep the specified time. time.sleep() takes seconds to sleep, so 20 * 60 is 20 minutes.

import time
run = raw_input("Start? > ")
time.sleep(20 * 60)

Check out Reuxables although it comes at a cost.

All the other answers use variables and SET operations. Here's a way to do it within a select statement. Just drop this in as a column in your existing select.

    (SELECT 
        '<table style=''font-family:"Verdana"; font-size: 10pt''>'
                    + '<tr bgcolor="#9DBED4"><th>col1</th><th>col2</th><th>col3</th><th>col4</th><th>col5</th></tr>'
                    + replace( replace( body, '&lt;', '<' ), '&gt;', '>' )
                    + '</table>'
    FROM
    (
        select cast( (
            select td = cast(col1 as varchar(5)) + '</td><td align="right">' + col2 + '</td><td>' + col3 + '</td><td align="right">' + cast(col4 as varchar(5)) + '</td><td align="right">' + cast(col5 as varchar(5)) + '</td>'
            from (
                    select col1  = col1,
                            col2 = col2,
                            col3 = col3,
                            col4 = col4,
                            col5 = col5
                    from m_LineLevel as onml
                    where onml.pkey = oni.pkey
                    ) as d
            for xml path( 'tr' ), type ) as varchar(max) ) as body
    ) as bodycte) as LineTable

You need to set the text after the replace call:

$('.element span').each(function() {_x000D_
  console.log($(this).text());_x000D_
  var text = $(this).text().replace('N/A, ', '');_x000D_
  $(this).text(text);_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div class="element">_x000D_
  <span>N/A, Category</span>_x000D_
</div>

Here's another cool way you can do it (hat tip @Felix King):

$(".element span").text(function(index, text) {
    return text.replace("N/A, ", "");
});

I would like to add one more thing to what the other answers have said. It is not compulsory that path will be:

C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\bin\git.exe

In my computer I did not found Git there.

BUT git and cmd are located in

git.exe

C:\Program Files\Git\bin\git.exe

cmd

C:\Program Files\Git\cmd

To add into PATH:

• Right-Click on My Computer
• Click on Advanced System Settings
• Click on Environment Variables
• Then, under System Variables, look for the path variable and click edit

• Add the path to git’s bin and cmd at the end of the string like this:

  ;C:\Program Files\Git\bin\git.exe;C:\Program Files\Git\cmd

OR

;C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\bin;C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\cmd

To verify, restart cmd and type git --version in cmd

This function uses only builtins

• Maybe consider evaling "$*" instead of running $@ directly depending on your needs

• It starts a job with the command string specified after the first arg that is the timeout value and monitors the job pid

• It checks every 1 seconds, bash supports timeouts down to 0.01 so that can be tweaked

• Also if your script needs stdin, read should rely on a dedicated fd (exec {tofd}<> <(:))

• Also you might want to tweak the kill signal (the one inside the loop) which is default to -15, you might want -9

## forking is evil
timeout() {
    to=$1; shift
    $@ & local wp=$! start=0
     while kill -0 $wp; do
        read -t 1
        start=$((start+1))
        if [ $start -ge $to ]; then
            kill $wp && break
        fi
    done
}

You had MarginTop instead of marginTop

It is also very buggy if you leave mid animation, here is update:

http://jsfiddle.net/kX7b6/3/

Note I changed it to mouseenter and mouseleave because I don't think the intention was to cancel the animation when you hover over the red or green area.

I need to give my user a web interface to change the session timeout interval. So, different installations of the web application would be able to have different timeouts for their sessions, but their web.xml cannot be different.

your question is simple, you need session timeout interval should be configurable at run time and configuration should be done through web interface and there shouldn't be overhead of restarting the server.

I am extending Michaels answer to address your question.

Logic: You need to store configured value in either .properties file or to database. On server start read that stored value and copy to a variable use that variable until server is UP. As config is updated update variable also. Thats it.

Expaination

In MyHttpSessionListener class 1. create a static variable with name globalSessionTimeoutInterval.

2. create a static block(executed for only for first time of class is being accessed) and read timeout value from config.properties file and set value to globalSessionTimeoutInterval variable.

3. Now use that value to set maxInactiveInterval

4. Now Web part i.e, Admin configuration page

   a. Copy configured value to static variable globalSessionTimeoutInterval.

   b. Write same value to config.properties file. (consider server is restarted then globalSessionTimeoutInterval will be loaded with value present in config.properties file)

5. Alternative .properties file OR storing it into database. Choice is yours.

Logical code for achieving the same

public class MyHttpSessionListener implements HttpSessionListener 
{
  public static Integer globalSessionTimeoutInterval = null;

  static
  {
      globalSessionTimeoutInterval =  Read value from .properties file or database;
  }
  public void sessionCreated(HttpSessionEvent event)
  {
      event.getSession().setMaxInactiveInterval(globalSessionTimeoutInterval);
  }

  public void sessionDestroyed(HttpSessionEvent event) {}

}

And in your Configuration Controller or Configuration servlet

String valueReceived = request.getParameter(timeoutValue);
if(valueReceived  != null)
{
    MyHttpSessionListener.globalSessionTimeoutInterval = Integer.parseInt(timeoutValue);
          //Store valueReceived to config.properties file or database
}

Here is an excerpt from this post that clarifies things nicely:

[..] in order to comprehend some principles, it’s important to realize when it’s been violated. This is what I will do now.

What does the violation of this principle mean? It implies that an object doesn’t fulfill the contract imposed by an abstraction expressed with an interface. In other words, it means that you identified your abstractions wrong.

Consider the following example:

interface Account
{
    /**
     * Withdraw $money amount from this account.
     *
     * @param Money $money
     * @return mixed
     */
    public function withdraw(Money $money);
}
class DefaultAccount implements Account
{
    private $balance;
    public function withdraw(Money $money)
    {
        if (!$this->enoughMoney($money)) {
            return;
        }
        $this->balance->subtract($money);
    }
}

Is this a violation of LSP? Yes. This is because the account’s contract tells us that an account would be withdrawn, but this is not always the case. So, what should I do in order to fix it? I just modify the contract:

interface Account
{
    /**
     * Withdraw $money amount from this account if its balance is enough.
     * Otherwise do nothing.
     *
     * @param Money $money
     * @return mixed
     */
    public function withdraw(Money $money);
}

Voilà, now the contract is satisfied.

This subtle violation often imposes a client with the ability to tell the difference between concrete objects employed. For example, given the first Account’s contract, it could look like the following:

class Client
{
    public function go(Account $account, Money $money)
    {
        if ($account instanceof DefaultAccount && !$account->hasEnoughMoney($money)) {
            return;
        }
        $account->withdraw($money);
    }
}

And, this automatically violates the open-closed principle [that is, for money withdrawal requirement. Because you never know what happens if an object violating the contract doesn't have enough money. Probably it just returns nothing, probably an exception will be thrown. So you have to check if it hasEnoughMoney() -- which is not part of an interface. So this forced concrete-class-dependent check is an OCP violation].

This point also addresses a misconception that I encounter quite often about LSP violation. It says the “if a parent’s behavior changed in a child, then, it violates LSP.” However, it doesn’t — as long as a child doesn’t violate its parent’s contract.

quick example:

#define debug(format, args...) fprintf (stderr, format, args)

If you want to convert all elements of a to a single numeric vector and length(a) is greater than 1 (OK, even if it is of length 1), you could unlist the object first and then convert.

as.numeric(unlist(a))
# [1]  10  38  66 101 129 185 283 374

Bear in mind that there aren't any quality controls here. Also, X$Days a mighty odd name.

In test file:

const APP_PORT = process.env.APP_PORT || 8080;

In the test script of ./package.json:

In ./env:

APP_PORT=8080

Declare your dim as a variant, and pull the data as you would from an array. i.e.

Dim y As Variant
y = Range("A1:B2")

Now your excel range is all 1 variable (array), y

To pull the data, call the array position in the range "A1:B2" or whatever you choose. e.g.:

Msgbox y(1, 1)

This will return the top left box in the "A1:B2" range.

It makes it easier for static typed languages (CLR) to interoperate with dynamic ones (python, ruby ...) running on the DLR (dynamic language runtime), see MSDN:

For example, you might use the following code to increment a counter in XML in C#.

Scriptobj.SetProperty("Count", ((int)GetProperty("Count")) + 1);

By using the DLR, you could use the following code instead for the same operation.

scriptobj.Count += 1;

MSDN lists these advantages:

• Simplifies Porting Dynamic Languages to the .NET Framework
• Enables Dynamic Features in Statically Typed Languages
• Provides Future Benefits of the DLR and .NET Framework
• Enables Sharing of Libraries and Objects
• Provides Fast Dynamic Dispatch and Invocation

See MSDN for more details.

You'd be much better off using the same array with both lists, and creating angular filters to achieve your goal.

http://docs.angularjs.org/guide/dev_guide.templates.filters.creating_filters

Rough, untested code follows:

appModule.filter('checked', function() {
    return function(input, checked) {
        if(!input)return input;
        var output = []
        for (i in input){
            var item = input[i];
            if(item.checked == checked)output.push(item);
        }
        return output
    }
});

and the view (i added an "uncheck" button too)

<div id="AddItem">
     <h3>Add Item</h3>

    <input value="1" type="number" placeholder="1" ng-model="itemAmount">
    <input value="" type="text" placeholder="Name of Item" ng-model="itemName">
    <br/>
    <button ng-click="addItem()">Add to list</button>
</div>
<!-- begin: LIST OF CHECKED ITEMS -->
<div id="CheckedList">
     <h3>Checked Items: {{getTotalCheckedItems()}}</h3>

     <h4>Checked:</h4>

    <table>
        <tr ng-repeat="item in items | checked:true" class="item-checked">
            <td><b>amount:</b> {{item.amount}} -</td>
            <td><b>name:</b> {{item.name}} -</td>
            <td> 
               <i>this item is checked!</i>
               <button ng-click="item.checked = false">uncheck item</button>

            </td>
        </tr>
    </table>
</div>
<!-- end: LIST OF CHECKED ITEMS -->
<!-- begin: LIST OF UNCHECKED ITEMS -->
<div id="UncheckedList">
     <h3>Unchecked Items: {{getTotalItems()}}</h3>

     <h4>Unchecked:</h4>

    <table>
        <tr ng-repeat="item in items | checked:false" class="item-unchecked">
            <td><b>amount:</b> {{item.amount}} -</td>
            <td><b>name:</b> {{item.name}} -</td>
            <td>
                <button ng-click="item.checked = true">check item</button>
            </td>
        </tr>
    </table>
</div>
<!-- end: LIST OF ITEMS -->

Then you dont need the toggle methods etc in your controller

Just read the docs:

This exception is thrown when no initial context implementation can be created. The policy of how an initial context implementation is selected is described in the documentation of the InitialContext class.

This exception can be thrown during any interaction with the InitialContext, not only when the InitialContext is constructed. For example, the implementation of the initial context might lazily retrieve the context only when actual methods are invoked on it. The application should not have any dependency on when the existence of an initial context is determined.

But this is explained much better in the docs for InitialContext

 <a type="button" href="#/new-page.html" class="btn btn-lg btn-success" >New Page</a>

Simple...

If you want to iterate over a list and create a new list with "transformed" objects, you should use the map() function of stream + collect(). In the following example I find all people with the last name "l1" and each person I'm "mapping" to a new Employee instance.

public class Test {

    public static void main(String[] args) {
        List<Person> persons = Arrays.asList(
                new Person("e1", "l1"),
                new Person("e2", "l1"),
                new Person("e3", "l2"),
                new Person("e4", "l2")
        );

        List<Employee> employees = persons.stream()
                .filter(p -> p.getLastName().equals("l1"))
                .map(p -> new Employee(p.getName(), p.getLastName(), 1000))
                .collect(Collectors.toList());

        System.out.println(employees);
    }

}

class Person {

    private String name;
    private String lastName;

    public Person(String name, String lastName) {
        this.name = name;
        this.lastName = lastName;
    }

    // Getter & Setter
}

class Employee extends Person {

    private double salary;

    public Employee(String name, String lastName, double salary) {
        super(name, lastName);
        this.salary = salary;
    }

    // Getter & Setter
}

In my experience the pythonw.exe is faster at least with using pygame.

This is just an Improvement of @soulcheck 's answer, and fix of the typo in forEach (missing closing bracket);

    server.get('/usersList', (req, res) => 
        User.find({}, (err, users) => 
            res.send(users.reduce((userMap, item) => {
                userMap[item.id] = item
                return userMap
            }, {}));
        );
    );

cheers!

Visual Studio Code:

Delete the files from your Explorer view. You see them crossed-out in your Branch view. Then commit and Sync.

Be aware: If files are on your .gitignore list, then the delete "update" will not be pushed and therefore not be visible. VS Code will warn you if this is the case, though. -> Exclude the files/folder from gitignore temporarily.

Use accept attribute with the MIME_type as values

<input type="file" accept="image/gif, image/jpeg" />

You can use the str.format() to make Python recognize any objects to strings.

<select name="owner">
<?php 
$sql = mysql_query("SELECT username FROM users");
while ($row = mysql_fetch_array($sql)){
echo "<option value=\"owner1\">" . $row['username'] . "</option>";
}
?>
</select>

Filestash is the perfect tool for that:

1. login to your bucket from https://www.filestash.app/s3-browser.html:

2. create a shared link:

3. Share it with the world

Also Filestash is open source. (Disclaimer: I am the author)

Be sure to test any solution across different Reader preferences. A site visitor may have their browser set to open the PDF in Reader/Acrobat as opposed to the browser, e.g., by disabling the Acrobat plugin in Firefox..

I can't be sure of my results, because I have two different Acrobat plugins that Firefox recognizes due to my having different versions of Adobe Acrobat and Adobe Reader, but it does appear that you at least need to test what happens if a website visitor has their browser set to not open the PDF in the browser. It could be quite annoying when they look at what appears to be an otherwise usable web page and their browser is nagging them to open a PDF file that they think they didn't request. In some cases, the PDF file spontaneously opened in Adobe Reader, not the browser, and in other cases the browser threw up a dialog saying the file didn't exist.

I ran into such mismatches with iframe and object both, different issues for different code.

This is for simple HTML code. I haven't tried the suggested frameworks.

This is an intuitive solution using the viewport command that just sets the minimum height to the viewport height minus the footer height.

html,body{
height: 100%
}
#nonFooter{
min-height: calc(100vh - 30px)
}

#footer {
height:30px;
margin: 0;
clear: both;
width:100%;
}

The z-index property only works on elements with a position value other than static (e.g. position: absolute;, position: relative;, or position: fixed).

There is also position: sticky; that is supported in Firefox, is prefixed in Safari, worked for a time in older versions of Chrome under a custom flag, and is under consideration by Microsoft to add to their Edge browser.

Important
For regular positioning, be sure to include position: relative on the elements where you also set the z-index. Otherwise, it won't take effect.

This happened to me in the following scenario:

I created a second project in my workspace, chose "Single View Application" for the template.

I then went to Interface Builder (main iPhone storyboard), added a UISwitch to the main view, and connected it to the view controller through both an IBOutlet and an IBAction (-valueChanged:).

On launch, the app crashes with the exception mentioned in the question. If I remove the switch from the view, it works.

After careful inspection, I realized I control-dragged the connections into the ViewController.h of another project in the same workspace. The 'Automatic' set of Interface Builder's Assistant Editor (a.k.a Tuxedo chest icon) chose as "counterpart" the wrong file (with the right name).

Hope this helps someone, specially because both 'Single View Application' and 'SpriteKit Game' project templates (in my case) create a default view controller class called "ViewController".

datetime.datetime.fromtimestamp() is correct, except you are probably having timestamp in miliseconds (like in JavaScript), but fromtimestamp() expects Unix timestamp, in seconds.

Do it like that:

>>> import datetime
>>> your_timestamp = 1331856000000
>>> date = datetime.datetime.fromtimestamp(your_timestamp / 1e3)

and the result is:

>>> date
datetime.datetime(2012, 3, 16, 1, 0)

Does it answer your question?

EDIT: J.F. Sebastian correctly suggested to use true division by 1e3 (float 1000). The difference is significant, if you would like to get precise results, thus I changed my answer. The difference results from the default behaviour of Python 2.x, which always returns int when dividing (using / operator) int by int (this is called floor division). By replacing the divisor 1000 (being an int) with the 1e3 divisor (being representation of 1000 as float) or with float(1000) (or 1000. etc.), the division becomes true division. Python 2.x returns float when dividing int by float, float by int, float by float etc. And when there is some fractional part in the timestamp passed to fromtimestamp() method, this method's result also contains information about that fractional part (as the number of microseconds).

div { margin: auto; }

This will center your div.

Div by itself is a blockelement. Therefor you need to define the style to the div how to behave.

The most important consideration is reliability. If a POST message gets lost the state of the system is undefined. Automatic recovery is impossible. For PUT messages, the state is undefined only until the first successful retry.

For instance, it may not be a good idea to create credit card transactions with POST.

If you happen to have auto generated URI's on your resource you can still use PUT by passing a generated URI (pointing to an empty resource) to the client.

Some other considerations:

• POST invalidates cached copies of the entire containing resource (better consistency)
• PUT responses are not cacheable while POST ones are (Require Content-Location and expiration)
• PUT is less supported by e.g. Java ME, older browsers, firewalls

Use this gem: https://rubygems.org/gems/active_record_importer

class Moulding < ActiveRecord::Base
  acts_as_importable
end

Then you may now use:

Moulding.import!(file: File.open(PATH_TO_FILE))

Just be sure to that your headers match the column names of your table

Try using Async instead to avoid blocking the only thread you have with NodeJS. Check this example:

const util = require('util');
const fs = require('fs');
const path = require('path');
const readFileAsync = util.promisify(fs.readFile);

const readContentFile = async (filePath) => {
  // Eureka, you are using good code practices here!
  const content = await readFileAsync(path.join(__dirname, filePath), {
    encoding: 'utf8'
  })
  return content;
}

Later can use this async function with try/catch from any other function:

const anyOtherFun = async () => {
  try {
    const fileContent = await readContentFile('my-file.txt');
  } catch (err) {
    // Here you get the error when the file was not found,
    // but you also get any other error
  }
}

Happy Coding!

Part of the answer to 'handle' the 'Sequence has no elements' Exception in VB is to test for empty

If Not (myMap Is Nothing) Then
' execute code
End if

Where MyMap is the sequence queried returning empty/null. FYI

You can create a folder with os.makedirs()
and use os.path.exists() to see if it already exists:

newpath = r'C:\Program Files\arbitrary' 
if not os.path.exists(newpath):
    os.makedirs(newpath)

If you're trying to make an installer: Windows Installer does a lot of work for you.

sudo service mysqld start

Worked for me, I'm using Centos

//add this to your css
    .myClass{
          margin 0 auto;

To find the Flutter SDK path [ used Windows10 ]

1. In your Android Studio home page on the bottom right click on Configure
2. Then Click on SDK Manager
3. Then on System Settings
4. Then on AndroidSDK

You will see the path at the top

To have access to stuff provided by math module, like pi. You need to import the module first:

import math

The lambda you are passing to forEach() is evaluated for each element received from the stream. The iteration itself is not visible from within the scope of the lambda, so you cannot continue it as if forEach() were a C preprocessor macro. Instead, you can conditionally skip the rest of the statements in it.

int* arr[8]; // An array of int pointers.
int (*arr)[8]; // A pointer to an array of integers

The third one is same as the first.

The general rule is operator precedence. It can get even much more complex as function pointers come into the picture.

Write own code because everyone uses a different class name. I am resetting jQuery validation by this code.

$('.error').remove();
        $('.is-invalid').removeClass('is-invalid');

Another option: when cell type is unknown at compile time and cell is formatted as Date Range.Value returns a desired DateTime object.

public static DateTime? GetAsDateTimeOrDefault(Range cell)
{
    object cellValue = cell.Value;
    if (cellValue is DateTime result)
    {
        return result;
    }
    return null;
}

v is a query parameter, technically you need to consider cases ala: http://www.youtube.com/watch?p=DB852818BF378DAC&v=1q-k-uN73Gk

In .NET I would recommend to use System.Web.HttpUtility.ParseQueryString

HttpUtility.ParseQueryString(url)["v"];

And you don't even need to check the key, as it will return null if the key is not in the collection.

You have to know what is your Entity-Framework version. Also after that you have to check project.json and control these sections:

In Dependencies

check:

Microsoft.EntityFrameworkCore.Tools": {
  "version": "1.0.0-preview2-final",
  "type": "build"
},

This section:

"version": "1.0.0-preview2-final",

is related with version of your Entity-Framework and you have to change this with that.

After that the second section of the proj.json is here, In the Tools section of JSON you have:

"Microsoft.EntityFrameworkCore.Tools": "1.0.0-preview2-final",

Also this part of code is related with your Entity-Framework and last part of code in Dependencies section.

Note: After do this issues you should to close CMD and restart visual studio.

You can always use an alias:

alias next='printf "blah_%02d" $count;count=$((count+1))'

you can use these commands from official page of github

https://help.github.com/en/github/using-git/changing-author-info

here is the commands

#!/bin/sh

git filter-branch --env-filter '

OLD_EMAIL="[email protected]"
CORRECT_NAME="Your Correct Name"
CORRECT_EMAIL="[email protected]"

if [ "$GIT_COMMITTER_EMAIL" = "$OLD_EMAIL" ]
then
export GIT_COMMITTER_NAME="$CORRECT_NAME"
export GIT_COMMITTER_EMAIL="$CORRECT_EMAIL"
fi
if [ "$GIT_AUTHOR_EMAIL" = "$OLD_EMAIL" ]
then
export GIT_AUTHOR_NAME="$CORRECT_NAME"
export GIT_AUTHOR_EMAIL="$CORRECT_EMAIL"
fi
' --tag-name-filter cat -- --branches --tags

here u can change the old email to ur new user name and email address.

Not so hard:

#include <thread>

void Test::runMultiThread()
{
    std::thread t1(&Test::calculate, this,  0, 10);
    std::thread t2(&Test::calculate, this, 11, 20);
    t1.join();
    t2.join();
}

If the result of the computation is still needed, use a future instead:

#include <future>

void Test::runMultiThread()
{
     auto f1 = std::async(&Test::calculate, this,  0, 10);
     auto f2 = std::async(&Test::calculate, this, 11, 20);

     auto res1 = f1.get();
     auto res2 = f2.get();
}

The answer about "short-circuiting" is potentially misleading, but has some truth (see below). In the R/S language, && and || only evaluate the first element in the first argument. All other elements in a vector or list are ignored regardless of the first ones value. Those operators are designed to work with the if (cond) {} else{} construction and to direct program control rather than construct new vectors.. The & and the | operators are designed to work on vectors, so they will be applied "in parallel", so to speak, along the length of the longest argument. Both vectors need to be evaluated before the comparisons are made. If the vectors are not the same length, then recycling of the shorter argument is performed.

When the arguments to && or || are evaluated, there is "short-circuiting" in that if any of the values in succession from left to right are determinative, then evaluations cease and the final value is returned.

> if( print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(FALSE && print(1) ) {print(2)} else {print(3)} # `print(1)` not evaluated
[1] 3
> if(TRUE && print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 2
> if(TRUE && !print(1) ) {print(2)} else {print(3)}
[1] 1
[1] 3
> if(FALSE && !print(1) ) {print(2)} else {print(3)}
[1] 3

The advantage of short-circuiting will only appear when the arguments take a long time to evaluate. That will typically occur when the arguments are functions that either process larger objects or have mathematical operations that are more complex.

This worked for me.

the reason why it returns < filter object > is that, filter is class instead of built-in function.

help(filter) you will get following: Help on class filter in module builtins:

To copy a directory's content to another directory you can use ansibles copy module:

- name: Copy content of directory 'files'
  copy:
    src: files/    # note the '/' <-- !!!
    dest: /tmp/files/

From the docs about the src parameter:

If (src!) path is a directory, it is copied recursively...
... if path ends with "/", only inside contents of that directory are copied to destination.
... if it does not end with "/", the directory itself with all contents is copied.

This should work:

s=json.dumps(variables)
variables2=json.loads(s)
assert(variables==variables2)

for the whole question:

cmd >> o.txt && [[ $(wc -l <o.txt) -eq 720 ]] && mv o.txt $(date +%F).o.txt

this will append 720 lines (30*24) into o.txt and after will rename the file based on the current date.

Run the above with the cron every hour, or

while :
do
    cmd >> o.txt && [[ $(wc -l <o.txt) -eq 720 ]] && mv o.txt $(date +%F).o.txt
    sleep 3600
done

Sets require their items to be hashable. Out of types predefined by Python only the immutable ones, such as strings, numbers, and tuples, are hashable. Mutable types, such as lists and dicts, are not hashable because a change of their contents would change the hash and break the lookup code.

Since you're sorting the list anyway, just place the duplicate removal after the list is already sorted. This is easy to implement, doesn't increase algorithmic complexity of the operation, and doesn't require changing sublists to tuples:

def uniq(lst):
    last = object()
    for item in lst:
        if item == last:
            continue
        yield item
        last = item

def sort_and_deduplicate(l):
    return list(uniq(sorted(l, reverse=True)))

Using @DrunkenDaddy extension function, in my case at least (creating EditText programmatically), it was displaying the keyboard on first click and then the date picker on second click.

Apparently, it's irrelevant to set isFocusable and isFocusableInTouchMode to false, because first click is always interpreted as a focus change by the EditText. So I had to trigger a click when the EditText gained focus. Now it works as expected: on first click it opens directly the date picker and never the keyboard (thanks to setting showSoftInputOnFocus to false):

fun EditText.transformIntoDatePicker(context: Context, format: String = "dd/MM/yyyy", maxDate: Date? = null) {
    isClickable = true
    showSoftInputOnFocus = false
    isCursorVisible = false

    setOnFocusChangeListener { _, hasFocus ->  if (hasFocus) callOnClick()}

    val myCalendar = Calendar.getInstance()
    val datePickerOnDataSetListener =
        DatePickerDialog.OnDateSetListener { _, year, monthOfYear, dayOfMonth ->
            myCalendar.set(Calendar.YEAR, year)
            myCalendar.set(Calendar.MONTH, monthOfYear)
            myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth)
            val sdf = SimpleDateFormat(format, Locale.getDefault())
            setText(sdf.format(myCalendar.time))
    }

    setOnClickListener {
        DatePickerDialog(
             context, datePickerOnDataSetListener, 
             myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
             myCalendar.get(Calendar.DAY_OF_MONTH)
        ).run {
            maxDate?.time?.also { datePicker.maxDate = it }
            show()
    }
}

These answers aren't really addressing the large confusion with between properties and attributes. Also, depending on the Javascript prototype, sometimes you can use a an element's property to access an attributes and sometimes you can't.

First, you have to remember that an HTMLElement is a Javascript object. Like all objects, they have properties. Sure, you can create a property called nearly anything you want inside HTMLElement, but it doesn't have to do anything with the DOM (what's on the page). The dot notation (.) is for properties. Now, there some special properties that are mapped to attributes, and at the time or writing there are only 4 that are guaranteed (more on that later).

All HTMLElements include a property called attributes. HTMLElement.attributes is a live NamedNodeMap Object that relates to the elements in the DOM. "Live" means that when the node changes in the DOM, they change on the JavaScript side, and vice versa. DOM attributes, in this case, are the nodes in question. A Node has a .nodeValue property that you can change. NamedNodeMap objects have a function called setNamedItem where you can change the entire node. You can also directly access the node by the key. For example, you can say .attributes["dir"] which is the same as .attributes.getNamedItem('dir'); (Side note, NamedNodeMap is case-insensitive, so you can also pass 'DIR');

There's a similar function directly in HTMLElement where you can just call setAttribute which will automatically create a node if it doesn't exist and set the nodeValue. There are also some attributes you can access directly as properties in HTMLElement via special properties, such as dir. Here's a rough mapping of what it looks like:

HTMLElement {
  attributes: {
    setNamedItem: function(attr, newAttr) { 
      this[attr] = newAttr;
    },    
    getNamedItem: function(attr) {
      return this[attr];
    },
    myAttribute1: {
      nodeName: 'myAttribute1',
      nodeValue: 'myNodeValue1'
    },
    myAttribute2: {
      nodeName: 'myAttribute2',
      nodeValue: 'myNodeValue2'
    },
  }
  setAttribute: function(attr, value) { 
    let item = this.attributes.getNamedItem(attr);
    if (!item) {
      item = document.createAttribute(attr);
      this.attributes.setNamedItem(attr, item);
    }
    item.nodeValue = value;
  },
  getAttribute: function(attr) { 
    return this.attributes[attr] && this.attributes[attr].nodeValue;
  },
  dir: // Special map to attributes.dir.nodeValue || ''
  id:  // Special map to attributes.id.nodeValue || ''
  className: // Special map to attributes.class.nodeValue || '' 
  lang: // Special map to attributes.lang.nodeValue || ''

}

So you can change the dir attributes 6 ways:

  // 1. Replace the node with setNamedItem
  const newAttribute = document.createAttribute('dir');
  newAttribute.nodeValue = 'rtl';
  element.attributes.setNamedItem(newAttribute);

  // 2. Replace the node by property name;
  const newAttribute2 = document.createAttribute('dir');
  newAttribute2.nodeValue = 'rtl';
  element.attributes['dir'] = newAttribute2;
  // OR
  element.attributes.dir = newAttribute2;

  // 3. Access node with getNamedItem and update nodeValue
  // Attribute must already exist!!!
  element.attributes.getNamedItem('dir').nodeValue = 'rtl';

  // 4. Access node by property update nodeValue
  // Attribute must already exist!!!
  element.attributes['dir'].nodeValue = 'rtl';
  // OR
  element.attributes.dir.nodeValue = 'rtl';

  // 5. use setAttribute()  
  element.setAttribute('dir', 'rtl');
  
  // 6. use the UNIQUELY SPECIAL dir property
  element["dir"] = 'rtl';
  element.dir = 'rtl';

You can update all properties with methods #1-5, but only dir, id, lang, and className with method #6.

Extensions of HTMLElement

HTMLElement has those 4 special properties. Some elements are extended classes of HTMLElement have even more mapped properties. For example, HTMLAnchorElement has HTMLAnchorElement.href, HTMLAnchorElement.rel, and HTMLAnchorElement.target. But, beware, if you set those properties on elements that do not have those special properties (like on a HTMLTableElement) then the attributes aren't changed and they are just, normal custom properties. To better understand, here's an example of its inheritance:

HTMLAnchorElement extends HTMLElement {
  // inherits all of HTMLElement
  href:    // Special map to attributes.href.nodeValue || ''
  target:  // Special map to attributes.target.nodeValue || ''
  rel:     // Special map to attributes.ref.nodeValue || '' 
}

Custom Properties

Now the big warning: Like all Javascript objects, you can add custom properties. But, those won't change anything on the DOM. You can do:

  const newElement = document.createElement('div');
  // THIS WILL NOT CHANGE THE ATTRIBUTE
  newElement.display = 'block';

But that's the same as

  newElement.myCustomDisplayAttribute = 'block';

This means that adding a custom property will not be linked to .attributes[attr].nodeValue.

Performance

I've built a jsperf test case to show the difference: https://jsperf.com/set-attribute-comparison. Basically, In order:

1. Custom properties because they don't affect the DOM and are not attributes.
2. Special mappings provided by the browser (dir, id, className).
3. If attributes already exists, element.attributes.ATTRIBUTENAME.nodeValue =
4. setAttribute();
5. If attributes already exists, element.attributes.getNamedItem(ATTRIBUTENAME).nodeValue = newValue
6. element.attributes.ATTRIBUTENAME = newNode
7. element.attributes.setNamedItem(ATTRIBUTENAME) = newNode

Conclusion (TL;DR)

• Use the special property mappings from HTMLElement: element.dir, element.id, element.className, or element.lang.

• If you are 100% sure the element is an extended HTMLElement with a special property, use that special mapping. (You can check with if (element instanceof HTMLAnchorElement)).

• If you are 100% sure the attribute already exists, use element.attributes.ATTRIBUTENAME.nodeValue = newValue.

• If not, use setAttribute().

You can check iOS Version and simply set the tint color of Navigation bar.

if (SYSTEM_VERSION_LESS_THAN(@"7.0")) {
    self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:0.9529 green:0.4392 blue:0.3333 alpha:1.0];
}else{

    self.navigationController.navigationBar.barTintColor = [UIColor colorWithRed:0.9529 green:0.4392 blue:0.3333 alpha:1.0];
    self.navigationItem.leftBarButtonItem.tintColor = [UIColor whiteColor];
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}

To get exact name of control, use:

    string controlName = Page.FindControl(Page.Request.Params["__EVENTTARGET"]).ID;

You're on the right track. The two constructors accept arguments, or you can specify them post-construction with ProcessBuilder#command(java.util.List) and ProcessBuilder#command(String...).

There is the tabindex property that can be set on component. It specifies in which order the input components should be iterated when selecting one and pressing tab. Values above 0 are reserved for custom navigation, 0 is "in natural order" (so would behave differently if set for the first element), -1 means not keyboard focusable:

<!-- navigate with tab key: -->
<input tabindex="1" type="text"/>
<input tabindex="2" type="text"/>

It can also be set for something else than the text input fields but it is not very obvious what it would do there, if anything at all. Even if the navigation works, maybe better to use "natural order" for anything else than the very obvious user input elements.

No, you do not need JQuery or any scripting at all to support this custom path of navigation. You can implement it on the server side without any JavaScript support. From the other side, the property also works fine in React framework but does not require it.

My implementation, works great in older ES versions:

sortObject = function(data) {
    var keys = Object.keys(data);
    var result = {};

    keys.sort();

    for(var i = 0; i < keys.length; i++) {
        var key = keys[i];

        result[key] = data[key];
    }

    return result;
};

You can use %~dp0 to get the path of the currently running batch file.

Edited to change directory to the VBS location before running

If you want the VBS to synchronously run in the same window, then

@echo off
pushd %~dp0
cscript necdaily.vbs

If you want the VBS to synchronously run in a new window, then

@echo off
pushd %~dp0
start /wait "" cmd /c cscript necdaily.vbs

If you want the VBS to asynchronously run in the same window, then

@echo off
pushd %~dp0
start /b "" cscript necdaily.vbs

If you want the VBS to asynchronously run in a new window, then

@echo off
pushd %~dp0
start "" cmd /c cscript necdaily.vbs

This will return you the required cursor

Cursor cursor = db.query(TABLE_NAME, new String[] {"_id", "title", "title_raw"}, 
                "title_raw like " + "'%Smith%'", null, null, null, null);

I use iFrame to insert the content from another page and CSS mentioned above is NOT working as expected. I have to use the parameter scrolling="no" even if I use HTML 5 Doctype

If you want to convert the HTML special characters and not just remove them as well as strip things down and prepare for plain text this was the solution that worked for me...

function htmlToPlainText($str){
    $str = str_replace(' ', ' ', $str);
    $str = html_entity_decode($str, ENT_QUOTES | ENT_COMPAT , 'UTF-8');
    $str = html_entity_decode($str, ENT_HTML5, 'UTF-8');
    $str = html_entity_decode($str);
    $str = htmlspecialchars_decode($str);
    $str = strip_tags($str);

    return $str;
}

$string = '<p>this is (&nbsp;) a test</p>
<div>Yes this is! &amp; does it get "processed"? </div>'

htmlToPlainText($string);
// "this is ( ) a test. Yes this is! & does it get processed?"`

html_entity_decode w/ ENT_QUOTES | ENT_XML1 converts things like ' htmlspecialchars_decode converts things like & html_entity_decode converts things like '< and strip_tags removes any HTML tags left over.

EDIT - Added str_replace(' ', ' ', $str); and several other html_entity_decode() as continued testing has shown a need for them.

As mentioned in other posts, simply catch the exception in DbEntityValidationException class. Which will give you watever you required during error cases.

 try
 {
  ....
 }
 catch(DbEntityValidationException ex)
 {
  ....
 }

Quite similar approve as already posted above. However it's easier to read.

/**
 * Remove all empty spaces from array a string array
 * @param arr array
 * @return array without ""
 */
public static String[] removeAllEmpty(String[] arr) {
    if (arr == null)
        return arr;

    String[] result = new String[arr.length];
    int amountOfValidStrings = 0;

    for (int i = 0; i < arr.length; i++) {
        if (!arr[i].equals(""))
            result[amountOfValidStrings++] = arr[i];
    }

    result = Arrays.copyOf(result, amountOfValidStrings);

    return result;
}

INDEX is a performance optimization technique that speeds up the data retrieval process. It is a persistent data structure that associated with a Table (or View) in order to increase performance during retrieving the data from that table (or View).

Index based search is applied more particularly when your queries include WHERE filter. Otherwise, i.e, a query without WHERE-filter selects whole data and process. Searching whole table without INDEX is called Table-scan.

You tagged your question [C] and [C++] at the same time. The results will be consistent between the languages, but the structure of the the answer is different for each of these languages.

In C language your examples has no relation to bool whatsoever (that applies to C99 as well). In C language relational operators do not produce bool results. Both 4 > 5 and 4 < 5 are expressions that produce results of type int with values 0 or 1. So, there's no "bool to int conversion" of any kind taking place in your examples in C.

In C++ relational operators do indeed produce bool results. bool values are convertible to int type, with true converting to 1 and false converting to 0. This is guaranteed by the language.

P.S. C language also has a dedicated boolean type _Bool (macro-aliased as bool), and its integral conversion rules are essentially the same as in C++. But nevertheless this is not relevant to your specific examples in C. Once again, relational operators in C always produce int (not bool) results regardless of the version of the language specification.

In combination with all the answers above, I wanted the ImageView to be pressed and changed state but if the user moved then "cancel" and not perform an onClickListener.

I ended up making a Point object within the class and setting its coordinates according to when the user pushed down on the ImageView. On the MotionEvent.ACTION_UP I recording a new point and compared the points.

I can only explain it so well, but here is what I did.

// set the ontouch listener
weatherView.setOnTouchListener(new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        // Determine what action with a switch statement
        switch (event.getAction()) {

        // User presses down on the ImageView, record the original point
        // and set the color filter
        case MotionEvent.ACTION_DOWN: {
            ImageView view = (ImageView) v;

            // overlay is black with transparency of 0x77 (119)
            view.getDrawable().setColorFilter(0x77000000,
                    PorterDuff.Mode.SRC_ATOP);
            view.invalidate();

            p = new Point((int) event.getX(), (int) event.getY());
            break;
        }

        // Once the user releases, record new point then compare the
        // difference, if within a certain range perform onCLick
        // and or otherwise clear the color filter
        case MotionEvent.ACTION_UP: {
            ImageView view = (ImageView) v;
            Point f = new Point((int) event.getX(), (int) event.getY());
            if ((Math.abs(f.x - p.x) < 15)
                    && ((Math.abs(f.x - p.x) < 15))) {
                view.performClick();
            }
            // clear the overlay
            view.getDrawable().clearColorFilter();
            view.invalidate();
            break;
        }
        }
        return true;
    }
});

I have an onClickListener set on the imageView, but this can be an method.

For your example, Dirk's answer is perfect. If you instead had a data frame and wanted to add that sort of sequence as a column, you could also use group from groupdata2 (disclaimer: my package) to greedily divide the datapoints into groups.

# Attach groupdata2
library(groupdata2)
# Create a random data frame
df <- data.frame("x" = rnorm(27))
# Create groups with 5 members each (except last group)
group(df, n = 5, method = "greedy")
         x .groups
     <dbl> <fct>  
 1  0.891  1      
 2 -1.13   1      
 3 -0.500  1      
 4 -1.12   1      
 5 -0.0187 1      
 6  0.420  2      
 7 -0.449  2      
 8  0.365  2      
 9  0.526  2      
10  0.466  2      
# … with 17 more rows

There's a whole range of methods for creating this kind of grouping factor. E.g. by number of groups, a list of group sizes, or by having groups start when the value in some column differs from the value in the previous row (e.g. if a column is c("x","x","y","z","z") the grouping factor would be c(1,1,2,3,3).

Had a similar problem. My solution was to give the inner table a fixed height of 1px and set the height of the td in the inner table to 100%. Against all odds, it works fine, tested in IE, Chrome and FF!

Remove the height will fix your problem because highchart is responsive by design if you adjust your screen it will also re-size.

On SQL Server? and on the same database server? Use three part naming.

INSERT INTO bar..tblFoobar( *fieldlist* )
SELECT *fieldlist* FROM foo..tblFoobar

This just moves the data. If you want to move the table definition (and other attributes such as permissions and indexes), you'll have to do something else.

This blog entry has a way to emulate border-color: transparent in IE6. The below example includes the "hasLayout" fix that is brought up in the blog entry comments:

/* transparent border */
.testDiv {
    width: 200px;
    height: 200px;
    border: solid 10px transparent;
}
/* IE6 fix */
*html .testDiv {
    zoom: 1;
    border-color: #FEFEFE;
    filter: chroma(color=#FEFEFE);
}

Make sure that the border-color used in the IE6 fix is not used anywhere in the .testDiv element. I changed the example from pink to #FEFEFE because that seems even less likely to be used.

You can also achieve this effect using XML, as seen here, which removes the limitation of the answers provided which all seem to include recursion in some fashion. The particular use I've made here allows for up to a 32-character delimiter, but that could be increased however large it needs to be.

create FUNCTION [dbo].[Split] (@sep VARCHAR(32), @s VARCHAR(MAX))
RETURNS TABLE
AS
    RETURN
    (
        SELECT r.value('.','VARCHAR(MAX)') as Item
        FROM (SELECT CONVERT(XML, N'<root><r>' + REPLACE(REPLACE(REPLACE(@s,'& ','&amp; '),'<','&lt;'), @sep, '</r><r>') + '</r></root>') as valxml) x
        CROSS APPLY x.valxml.nodes('//root/r') AS RECORDS(r)
    )

Then you can invoke it using:

SELECT * FROM dbo.Split(' ', 'I hate bunnies')

Which returns:

-----------
|I        |
|---------|
|hate     |
|---------|
|bunnies  |
-----------

CREATE FUNCTION [dbo].[Split] (@sep VARCHAR(32), @s VARCHAR(MAX))
RETURNS TABLE
AS
    RETURN
    (
        SELECT r.value('.','VARCHAR(MAX)') as Item
        FROM (SELECT CONVERT(XML, N'<root><r>' + REPLACE(@s, @sep, '</r><r>') + '</r></root>') as valxml) x
        CROSS APPLY x.valxml.nodes('//root/r') AS RECORDS(r)
    )

Above, Abhishek mentions the command line differences specified in two URLS:

1. PhoneGap: http://docs.phonegap.com/en/edge/guide_cli_index.md.html

2. Cordova: http://cordova.apache.org/docs/en/3.0.0/guide_cli_index.md.html#The%20Command-line%20Interface

One thing to point out is that, as of this post, the phonegap one looks to be almost the same as the cordova one, and is probably not an accurate image of the command line option differences. As such, I installed both on my system so I could look at the differences.

These are just a few of them. Hopefully they are brought more in sync sometime. If anyone has better information, please tell me.

1. Adding platforms seems to be done differently between the two commands ( phonegap uses "install" command, cordova uses "platform add" command )
2. Adding/creating projects seems to be the same between the two commands ( same command line options supported )
3. Obviously, as has been stated, phonegap can use PhoneGap Build, so it has the corresponding options to trigger that or local builds
4. Quite a few other significant command line differences, simply by running "cordova help" and "phonegap help" and comparing the two.

I guess my point is that the phonegap CLI documention mentioned quite often is not really for the phonegap CLI, but for the cordova CLI, at this time. Please tell me if I am missing something. Thanks.

if x is a string and you search for y which also a string their is two cases : case 1: y is exist in x so x.find(y) = the index (the position) of the y in x . case 2: y is not exist so x.find (y) = -1 this mean y is not found in x.

This article can provide a lot of insight here: http://redis.io/topics/memory-optimization

There are many ways to store an array of Objects in Redis (spoiler: I like option 1 for most use cases):

1. Store the entire object as JSON-encoded string in a single key and keep track of all Objects using a set (or list, if more appropriate). For example:

   INCR id:users
   SET user:{id} '{"name":"Fred","age":25}'
   SADD users {id}
   

   Generally speaking, this is probably the best method in most cases. If there are a lot of fields in the Object, your Objects are not nested with other Objects, and you tend to only access a small subset of fields at a time, it might be better to go with option 2.

   Advantages: considered a "good practice." Each Object is a full-blown Redis key. JSON parsing is fast, especially when you need to access many fields for this Object at once. Disadvantages: slower when you only need to access a single field.

2. Store each Object's properties in a Redis hash.

   INCR id:users
   HMSET user:{id} name "Fred" age 25
   SADD users {id}
   

   Advantages: considered a "good practice." Each Object is a full-blown Redis key. No need to parse JSON strings. Disadvantages: possibly slower when you need to access all/most of the fields in an Object. Also, nested Objects (Objects within Objects) cannot be easily stored.

3. Store each Object as a JSON string in a Redis hash.

   INCR id:users
   HMSET users {id} '{"name":"Fred","age":25}'
   

   This allows you to consolidate a bit and only use two keys instead of lots of keys. The obvious disadvantage is that you can't set the TTL (and other stuff) on each user Object, since it is merely a field in the Redis hash and not a full-blown Redis key.

   Advantages: JSON parsing is fast, especially when you need to access many fields for this Object at once. Less "polluting" of the main key namespace. Disadvantages: About same memory usage as #1 when you have a lot of Objects. Slower than #2 when you only need to access a single field. Probably not considered a "good practice."

4. Store each property of each Object in a dedicated key.

   INCR id:users
   SET user:{id}:name "Fred"
   SET user:{id}:age 25
   SADD users {id}
   

   According to the article above, this option is almost never preferred (unless the property of the Object needs to have specific TTL or something).

   Advantages: Object properties are full-blown Redis keys, which might not be overkill for your app. Disadvantages: slow, uses more memory, and not considered "best practice." Lots of polluting of the main key namespace.

Overall Summary

Option 4 is generally not preferred. Options 1 and 2 are very similar, and they are both pretty common. I prefer option 1 (generally speaking) because it allows you to store more complicated Objects (with multiple layers of nesting, etc.) Option 3 is used when you really care about not polluting the main key namespace (i.e. you don't want there to be a lot of keys in your database and you don't care about things like TTL, key sharding, or whatever).

If I got something wrong here, please consider leaving a comment and allowing me to revise the answer before downvoting. Thanks! :)

My problem was that I had this: Instead of this:

You can use numpy.nan_to_num :

numpy.nan_to_num(x) : Replace nan with zero and inf with finite numbers.

Example (see doc) :

>>> np.set_printoptions(precision=8)
>>> x = np.array([np.inf, -np.inf, np.nan, -128, 128])
>>> np.nan_to_num(x)
array([  1.79769313e+308,  -1.79769313e+308,   0.00000000e+000,
        -1.28000000e+002,   1.28000000e+002])

This query here will list the total size that a table takes up - clustered index, heap and all nonclustered indices:

SELECT 
    s.Name AS SchemaName,
    t.NAME AS TableName,
    p.rows AS RowCounts,
    SUM(a.total_pages) * 8 AS TotalSpaceKB, 
    SUM(a.used_pages) * 8 AS UsedSpaceKB, 
    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM 
    sys.tables t
INNER JOIN 
    sys.schemas s ON s.schema_id = t.schema_id
INNER JOIN      
    sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN 
    sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN 
    sys.allocation_units a ON p.partition_id = a.container_id
WHERE 
    t.NAME NOT LIKE 'dt%'    -- filter out system tables for diagramming
    AND t.is_ms_shipped = 0
    AND i.OBJECT_ID > 255 
GROUP BY 
    t.Name, s.Name, p.Rows
ORDER BY 
    s.Name, t.Name

If you want to separate table space from index space, you need to use AND i.index_id IN (0,1) for the table space (index_id = 0 is the heap space, index_id = 1 is the size of the clustered index = data pages) and AND i.index_id > 1 for the index-only space

We need to cover at least these aspects to provide a comprehensive answer/comparison (in no particular order of importance): Speed, Memory usage, Syntax and Features.

My intent is to cover each one of these as clearly as possible from data.table perspective.

Note: unless explicitly mentioned otherwise, by referring to dplyr, we refer to dplyr's data.frame interface whose internals are in C++ using Rcpp.

The data.table syntax is consistent in its form - DT[i, j, by]. To keep i, j and by together is by design. By keeping related operations together, it allows to easily optimise operations for speed and more importantly memory usage, and also provide some powerful features, all while maintaining the consistency in syntax.

1. Speed

Quite a few benchmarks (though mostly on grouping operations) have been added to the question already showing data.table gets faster than dplyr as the number of groups and/or rows to group by increase, including benchmarks by Matt on grouping from 10 million to 2 billion rows (100GB in RAM) on 100 - 10 million groups and varying grouping columns, which also compares pandas. See also updated benchmarks, which include Spark and pydatatable as well.

On benchmarks, it would be great to cover these remaining aspects as well:

• Grouping operations involving a subset of rows - i.e., DT[x > val, sum(y), by = z] type operations.

• Benchmark other operations such as update and joins.

• Also benchmark memory footprint for each operation in addition to runtime.

2. Memory usage

1. Operations involving filter() or slice() in dplyr can be memory inefficient (on both data.frames and data.tables). See this post.

   Note that Hadley's comment talks about speed (that dplyr is plentiful fast for him), whereas the major concern here is memory.

2. data.table interface at the moment allows one to modify/update columns by reference (note that we don't need to re-assign the result back to a variable).

   # sub-assign by reference, updates 'y' in-place
   DT[x >= 1L, y := NA]
   

   But dplyr will never update by reference. The dplyr equivalent would be (note that the result needs to be re-assigned):

   # copies the entire 'y' column
   ans <- DF %>% mutate(y = replace(y, which(x >= 1L), NA))
   

   A concern for this is referential transparency. Updating a data.table object by reference, especially within a function may not be always desirable. But this is an incredibly useful feature: see this and this posts for interesting cases. And we want to keep it.

   Therefore we are working towards exporting shallow() function in data.table that will provide the user with both possibilities. For example, if it is desirable to not modify the input data.table within a function, one can then do:

   foo <- function(DT) {
       DT = shallow(DT)          ## shallow copy DT
       DT[, newcol := 1L]        ## does not affect the original DT 
       DT[x > 2L, newcol := 2L]  ## no need to copy (internally), as this column exists only in shallow copied DT
       DT[x > 2L, x := 3L]       ## have to copy (like base R / dplyr does always); otherwise original DT will 
                                 ## also get modified.
   }
   

   By not using shallow(), the old functionality is retained:

   bar <- function(DT) {
       DT[, newcol := 1L]        ## old behaviour, original DT gets updated by reference
       DT[x > 2L, x := 3L]       ## old behaviour, update column x in original DT.
   }
   

   By creating a shallow copy using shallow(), we understand that you don't want to modify the original object. We take care of everything internally to ensure that while also ensuring to copy columns you modify only when it is absolutely necessary. When implemented, this should settle the referential transparency issue altogether while providing the user with both possibilties.

   Also, once shallow() is exported dplyr's data.table interface should avoid almost all copies. So those who prefer dplyr's syntax can use it with data.tables.

   But it will still lack many features that data.table provides, including (sub)-assignment by reference.

3. Aggregate while joining:

   Suppose you have two data.tables as follows:

   DT1 = data.table(x=c(1,1,1,1,2,2,2,2), y=c("a", "a", "b", "b"), z=1:8, key=c("x", "y"))
   #    x y z
   # 1: 1 a 1
   # 2: 1 a 2
   # 3: 1 b 3
   # 4: 1 b 4
   # 5: 2 a 5
   # 6: 2 a 6
   # 7: 2 b 7
   # 8: 2 b 8
   DT2 = data.table(x=1:2, y=c("a", "b"), mul=4:3, key=c("x", "y"))
   #    x y mul
   # 1: 1 a   4
   # 2: 2 b   3
   

   And you would like to get sum(z) * mul for each row in DT2 while joining by columns x,y. We can either:

   • 1) aggregate DT1 to get sum(z), 2) perform a join and 3) multiply (or)

     # data.table way
     DT1[, .(z = sum(z)), keyby = .(x,y)][DT2][, z := z*mul][]
     
     # dplyr equivalent
     DF1 %>% group_by(x, y) %>% summarise(z = sum(z)) %>% 
         right_join(DF2) %>% mutate(z = z * mul)
     

   • 2) do it all in one go (using by = .EACHI feature):

     DT1[DT2, list(z=sum(z) * mul), by = .EACHI]
     

   What is the advantage?

   • We don't have to allocate memory for the intermediate result.

   • We don't have to group/hash twice (one for aggregation and other for joining).

   • And more importantly, the operation what we wanted to perform is clear by looking at j in (2).

   Check this post for a detailed explanation of by = .EACHI. No intermediate results are materialised, and the join+aggregate is performed all in one go.

   Have a look at this, this and this posts for real usage scenarios.

   In dplyr you would have to join and aggregate or aggregate first and then join, neither of which are as efficient, in terms of memory (which in turn translates to speed).

4. Update and joins:

   Consider the data.table code shown below:

   DT1[DT2, col := i.mul]
   

   adds/updates DT1's column col with mul from DT2 on those rows where DT2's key column matches DT1. I don't think there is an exact equivalent of this operation in dplyr, i.e., without avoiding a *_join operation, which would have to copy the entire DT1 just to add a new column to it, which is unnecessary.

   Check this post for a real usage scenario.

To summarise, it is important to realise that every bit of optimisation matters. As Grace Hopper would say, Mind your nanoseconds!

3. Syntax

Let's now look at syntax. Hadley commented here:

Data tables are extremely fast but I think their concision makes it harder to learn and code that uses it is harder to read after you have written it ...

I find this remark pointless because it is very subjective. What we can perhaps try is to contrast consistency in syntax. We will compare data.table and dplyr syntax side-by-side.

We will work with the dummy data shown below:

DT = data.table(x=1:10, y=11:20, z=rep(1:2, each=5))
DF = as.data.frame(DT)

1. Basic aggregation/update operations.

   # case (a)
   DT[, sum(y), by = z]                       ## data.table syntax
   DF %>% group_by(z) %>% summarise(sum(y)) ## dplyr syntax
   DT[, y := cumsum(y), by = z]
   ans <- DF %>% group_by(z) %>% mutate(y = cumsum(y))
   
   # case (b)
   DT[x > 2, sum(y), by = z]
   DF %>% filter(x>2) %>% group_by(z) %>% summarise(sum(y))
   DT[x > 2, y := cumsum(y), by = z]
   ans <- DF %>% group_by(z) %>% mutate(y = replace(y, which(x > 2), cumsum(y)))
   
   # case (c)
   DT[, if(any(x > 5L)) y[1L]-y[2L] else y[2L], by = z]
   DF %>% group_by(z) %>% summarise(if (any(x > 5L)) y[1L] - y[2L] else y[2L])
   DT[, if(any(x > 5L)) y[1L] - y[2L], by = z]
   DF %>% group_by(z) %>% filter(any(x > 5L)) %>% summarise(y[1L] - y[2L])
   

   • data.table syntax is compact and dplyr's quite verbose. Things are more or less equivalent in case (a).

   • In case (b), we had to use filter() in dplyr while summarising. But while updating, we had to move the logic inside mutate(). In data.table however, we express both operations with the same logic - operate on rows where x > 2, but in first case, get sum(y), whereas in the second case update those rows for y with its cumulative sum.

     This is what we mean when we say the DT[i, j, by] form is consistent.

   • Similarly in case (c), when we have if-else condition, we are able to express the logic "as-is" in both data.table and dplyr. However, if we would like to return just those rows where the if condition satisfies and skip otherwise, we cannot use summarise() directly (AFAICT). We have to filter() first and then summarise because summarise() always expects a single value.

     While it returns the same result, using filter() here makes the actual operation less obvious.

     It might very well be possible to use filter() in the first case as well (does not seem obvious to me), but my point is that we should not have to.

2. Aggregation / update on multiple columns

   # case (a)
   DT[, lapply(.SD, sum), by = z]                     ## data.table syntax
   DF %>% group_by(z) %>% summarise_each(funs(sum)) ## dplyr syntax
   DT[, (cols) := lapply(.SD, sum), by = z]
   ans <- DF %>% group_by(z) %>% mutate_each(funs(sum))
   
   # case (b)
   DT[, c(lapply(.SD, sum), lapply(.SD, mean)), by = z]
   DF %>% group_by(z) %>% summarise_each(funs(sum, mean))
   
   # case (c)
   DT[, c(.N, lapply(.SD, sum)), by = z]     
   DF %>% group_by(z) %>% summarise_each(funs(n(), mean))
   

   • In case (a), the codes are more or less equivalent. data.table uses familiar base function lapply(), whereas dplyr introduces *_each() along with a bunch of functions to funs().

   • data.table's := requires column names to be provided, whereas dplyr generates it automatically.

   • In case (b), dplyr's syntax is relatively straightforward. Improving aggregations/updates on multiple functions is on data.table's list.

   • In case (c) though, dplyr would return n() as many times as many columns, instead of just once. In data.table, all we need to do is to return a list in j. Each element of the list will become a column in the result. So, we can use, once again, the familiar base function c() to concatenate .N to a list which returns a list.

   Note: Once again, in data.table, all we need to do is return a list in j. Each element of the list will become a column in result. You can use c(), as.list(), lapply(), list() etc... base functions to accomplish this, without having to learn any new functions.

   You will need to learn just the special variables - .N and .SD at least. The equivalent in dplyr are n() and .

3. Joins

   dplyr provides separate functions for each type of join where as data.table allows joins using the same syntax DT[i, j, by] (and with reason). It also provides an equivalent merge.data.table() function as an alternative.

   setkey(DT1, x, y)
   
   # 1. normal join
   DT1[DT2]            ## data.table syntax
   left_join(DT2, DT1) ## dplyr syntax
   
   # 2. select columns while join    
   DT1[DT2, .(z, i.mul)]
   left_join(select(DT2, x, y, mul), select(DT1, x, y, z))
   
   # 3. aggregate while join
   DT1[DT2, .(sum(z) * i.mul), by = .EACHI]
   DF1 %>% group_by(x, y) %>% summarise(z = sum(z)) %>% 
       inner_join(DF2) %>% mutate(z = z*mul) %>% select(-mul)
   
   # 4. update while join
   DT1[DT2, z := cumsum(z) * i.mul, by = .EACHI]
   ??
   
   # 5. rolling join
   DT1[DT2, roll = -Inf]
   ??
   
   # 6. other arguments to control output
   DT1[DT2, mult = "first"]
   ??
   

   • Some might find a separate function for each joins much nicer (left, right, inner, anti, semi etc), whereas as others might like data.table's DT[i, j, by], or merge() which is similar to base R.

   • However dplyr joins do just that. Nothing more. Nothing less.

   • data.tables can select columns while joining (2), and in dplyr you will need to select() first on both data.frames before to join as shown above. Otherwise you would materialiase the join with unnecessary columns only to remove them later and that is inefficient.

   • data.tables can aggregate while joining (3) and also update while joining (4), using by = .EACHI feature. Why materialse the entire join result to add/update just a few columns?

   • data.table is capable of rolling joins (5) - roll forward, LOCF, roll backward, NOCB, nearest.

   • data.table also has mult = argument which selects first, last or all matches (6).

   • data.table has allow.cartesian = TRUE argument to protect from accidental invalid joins.

Once again, the syntax is consistent with DT[i, j, by] with additional arguments allowing for controlling the output further.

4. do()...

   dplyr's summarise is specially designed for functions that return a single value. If your function returns multiple/unequal values, you will have to resort to do(). You have to know beforehand about all your functions return value.

   DT[, list(x[1], y[1]), by = z]                 ## data.table syntax
   DF %>% group_by(z) %>% summarise(x[1], y[1]) ## dplyr syntax
   DT[, list(x[1:2], y[1]), by = z]
   DF %>% group_by(z) %>% do(data.frame(.$x[1:2], .$y[1]))
   
   DT[, quantile(x, 0.25), by = z]
   DF %>% group_by(z) %>% summarise(quantile(x, 0.25))
   DT[, quantile(x, c(0.25, 0.75)), by = z]
   DF %>% group_by(z) %>% do(data.frame(quantile(.$x, c(0.25, 0.75))))
   
   DT[, as.list(summary(x)), by = z]
   DF %>% group_by(z) %>% do(data.frame(as.list(summary(.$x))))
   

   • .SD's equivalent is .

   • In data.table, you can throw pretty much anything in j - the only thing to remember is for it to return a list so that each element of the list gets converted to a column.

   • In dplyr, cannot do that. Have to resort to do() depending on how sure you are as to whether your function would always return a single value. And it is quite slow.

Once again, data.table's syntax is consistent with DT[i, j, by]. We can just keep throwing expressions in j without having to worry about these things.

Have a look at this SO question and this one. I wonder if it would be possible to express the answer as straightforward using dplyr's syntax...

To summarise, I have particularly highlighted several instances where dplyr's syntax is either inefficient, limited or fails to make operations straightforward. This is particularly because data.table gets quite a bit of backlash about "harder to read/learn" syntax (like the one pasted/linked above). Most posts that cover dplyr talk about most straightforward operations. And that is great. But it is important to realise its syntax and feature limitations as well, and I am yet to see a post on it.

data.table has its quirks as well (some of which I have pointed out that we are attempting to fix). We are also attempting to improve data.table's joins as I have highlighted here.

But one should also consider the number of features that dplyr lacks in comparison to data.table.

4. Features

I have pointed out most of the features here and also in this post. In addition:

• fread - fast file reader has been available for a long time now.

• fwrite - a parallelised fast file writer is now available. See this post for a detailed explanation on the implementation and #1664 for keeping track of further developments.

• Automatic indexing - another handy feature to optimise base R syntax as is, internally.

• Ad-hoc grouping: dplyr automatically sorts the results by grouping variables during summarise(), which may not be always desirable.

• Numerous advantages in data.table joins (for speed / memory efficiency and syntax) mentioned above.

• Non-equi joins: Allows joins using other operators <=, <, >, >= along with all other advantages of data.table joins.

• Overlapping range joins was implemented in data.table recently. Check this post for an overview with benchmarks.

• setorder() function in data.table that allows really fast reordering of data.tables by reference.

• dplyr provides interface to databases using the same syntax, which data.table does not at the moment.

• data.table provides faster equivalents of set operations (written by Jan Gorecki) - fsetdiff, fintersect, funion and fsetequal with additional all argument (as in SQL).

• data.table loads cleanly with no masking warnings and has a mechanism described here for [.data.frame compatibility when passed to any R package. dplyr changes base functions filter, lag and [ which can cause problems; e.g. here and here.

Finally:

• On databases - there is no reason why data.table cannot provide similar interface, but this is not a priority now. It might get bumped up if users would very much like that feature.. not sure.

• On parallelism - Everything is difficult, until someone goes ahead and does it. Of course it will take effort (being thread safe).

  • Progress is being made currently (in v1.9.7 devel) towards parallelising known time consuming parts for incremental performance gains using OpenMP.

You can use the array_key_exists() built-in function:

if (array_key_exists('id', $_GET)) {
    echo $_GET['id'];
}

or the isset() built-in function:

if (isset($_GET['id'])) {
    echo $_GET['id'];
}

JavaScript does not have such declarations. It would be:

var cubes = ...

regardless

But you can do:

for(var i = 0; i < cubes.length; i++)
{
  for(var j = 0; j < cubes[i].length; j++)
  {

  }
}

Note that JavaScript allows jagged arrays, like:

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

since arrays can contain any type of object, including an array of arbitrary length.

As noted by MDC:

"for..in should not be used to iterate over an Array where index order is important"

If you use your original syntax, there is no guarantee the elements will be visited in numeric order.

For newbies like me, who end up on this question: This error also happens if you attempt to call .select2() on an element retrieved using pure javascript and not using jQuery.

This fails with the "select2 is not a function" error:

document.getElementById('e9').select2();

This works:

$("#e9").select2();

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

I wanted to comment on @Ionica Bizau, but I don't have enough reputation.
To give a reply to your question about javascript code:
What you need to do is get the parent's element height (minus any elements that take up space) and apply that to the child elements.

function wrapperHeight(){
    var height = $(window).outerHeight() - $('#header').outerHeight(true);
    $('.wrapper').css({"max-height":height+"px"});      
}

Note
window could be replaced by ".container" if that one has no floated children or has a fix to get the correct height calculated. This solution uses jQuery.

Regexp solution:

ref = ref.replace(/^F0/, "");

plain solution:

if (ref.substr(0, 2) == "F0")
     ref = ref.substr(2);

We were also facing this issue when using IE version 11 to access our React app (create-react-app with react version 16.0.0 with jQuery v3.1.1) on the enterprise intranet. To solve it, i simply followed the directions at this url which are also listed below:

1. Make sure to set the DOCTYPE to standards mode by making sure the first line of the master file is: <!DOCTYPE html>

2. Force IE 11 to use the latest internal version by including the following meta tag in the head tag: <meta http-equiv="X-UA-Compatible" content="IE=edge;" />

NOTE: I did not face the problem when using IE to access the app in development mode on my local machine (localhost:3000). The problem occurred only when accessing the app deployed to the DEV server on the company Intranet, probably because of some company wide Windows OS policy settings and/or IE Internet Options.

Or

jar xvf myproject.war

I recently wrote a gem to simplify this process and to neaten up your views, etc etc.

Check it out at: http://github.com/platform45/easy_dates

I faced the same issue while trying to transpile some jsx with babel. Below is the solution that worked for me. You can add the following json to your .babelrc

{
  "presets": [
    [
      "@babel/preset-react",
      { "targets": { "browsers": ["last 3 versions", "safari >= 6"] } }
    ]
  ],
  "plugins": [["@babel/plugin-proposal-class-properties"]]
}

You can also use weightSum and layout_weight property to adjust your different screen.

For that, you have to make android:layout_width = 0dp, and android:layout_width = (whatever you want);

To fix this install the php7.0-mbstring package:

sudo apt install php7.0-mbstring

C++11 standard on == for std::vector

Others have mentioned that operator== does compare vector contents and works, but here is a quote from the C++11 N3337 standard draft which I believe implies that.

We first look at Chapter 23.2.1 "General container requirements", which documents things that must be valid for all containers, including therefore std::vector.

That section Table 96 "Container requirements" which contains an entry:

Expression   Operational semantics
===========  ======================
a == b       distance(a.begin(), a.end()) == distance(b.begin(), b.end()) &&
             equal(a.begin(), a.end(), b.begin())

The distance part of the semantics means that the size of both containers are the same, but stated in a generalized iterator friendly way for non random access addressable containers. distance() is defined at 24.4.4 "Iterator operations".

Then the key question is what does equal() mean. At the end of the table we see:

Notes: the algorithm equal() is defined in Clause 25.

and in section 25.2.11 "Equal" we find its definition:

template<class InputIterator1, class InputIterator2>
bool equal(InputIterator1 first1, InputIterator1 last1,
           InputIterator2 first2);

template<class InputIterator1, class InputIterator2,
class BinaryPredicate>
bool equal(InputIterator1 first1, InputIterator1 last1,
           InputIterator2 first2, BinaryPredicate pred);

1 Returns: true if for every iterator i in the range [first1,last1) the following corresponding conditions hold: *i == *(first2 + (i - first1)), pred(*i, *(first2 + (i - first1))) != false. Otherwise, returns false.

In our case, we care about the overloaded version without BinaryPredicate version, which corresponds to the first pseudo code definition *i == *(first2 + (i - first1)), which we see is just an iterator-friendly definition of "all iterated items are the same".

Similar questions for other containers:

• how to compare two std::set?

try this out

$("div[id^='car']:last").after($('#car2').clone());

As already noted in a previous answer, this situation may arise due to line-ending problems (CR/LF vs. LF). I solved this problem (under Git version 2.22.0) with this command:

git add --renormalize .

According to the manual:

       --renormalize
           Apply the "clean" process freshly to all tracked files to
           forcibly add them again to the index. This is useful after
           changing core.autocrlf configuration or the text attribute in
           order to correct files added with wrong CRLF/LF line endings.
           This option implies -u.

You can use [(ngModel)], but you'll need to update your value to [value] otherwise the value is evaluating as a string. It would look like this:

<label>This rule is true if:</label>
<label class="form-check-inline">
    <input class="form-check-input" type="radio" name="mode" [value]="true" [(ngModel)]="rule.mode">
</label>
<label class="form-check-inline">
    <input class="form-check-input" type="radio" name="mode" [value]="false" [(ngModel)]="rule.mode">
</label>

If rule.mode is true, then that radio is selected. If it's false, then the other.

The difference really comes down to the value. value="true" really evaluates to the string 'true', whereas [value]="true" evaluates to the boolean true.

Docker treats lines that begin with # as a comment, unless the line is a valid parser directive. A # marker anywhere else in a line is treated as an argument.

example code:

# this line is a comment

RUN echo 'we are running some # of cool things'

Output:

we are running some # of cool things

This method of selection is built-in and well covered in the Vim help. It covers XML tags and more.

See :help text-objects.

It's simple. You can create your own ViewModel class for Login - LoginViewModel. You can create view var dialog = new UserView(); inside your LoginViewModel. And you can set-up Command LoginCommand into button.

<Button Name="btnLogin" IsDefault="True" Content="Login" Command="{Binding LoginCommand}" />

and

<Button Name="btnCancel" IsDefault="True" Content="Login" Command="{Binding CancelCommand}" />

ViewModel class:

public class LoginViewModel
{
    Window dialog;
    public bool ShowLogin()
    {
       dialog = new UserView();
       dialog.DataContext = this; // set up ViewModel into View
       if (dialog.ShowDialog() == true)
       {
         return true;
       }

       return false;
    }

    ICommand _loginCommand
    public ICommand LoginCommand
    {
        get
        {
            if (_loginCommand == null)
                _loginCommand = new RelayCommand(param => this.Login());

            return _loginCommand;
        }
    }

    public void CloseLoginView()
    {
            if (dialog != null)
          dialog.Close();
    }   

    public void Login()
    {
        if(CheckLogin()==true)
        {
            CloseLoginView();         
        }
        else
        {
          // write error message
        }
    }

    public bool CheckLogin()
    {
      // ... check login code
      return true;
    }
}

Don't use the xcopy, use copy instead, it doesn't have this issue.

xcopy is generally used when performing recursive copies of multiple files/folders, or when you need the verification/prompting features it offers. For single file copies, the copy command works just fine.

See ?options:

options(max.print=999999)

In psql that would be

\dx

See the manual for details: http://www.postgresql.org/docs/current/static/app-psql.html

Doing it in plain SQL it would be a select on pg_extension:

SELECT * 
FROM pg_extension

http://www.postgresql.org/docs/current/static/catalog-pg-extension.html

You shouldn't edit it, you should completely scrap it.

Any attempt to make execution stop for a certain amount of time will lock up the browser and switch it to a Not Responding state. The only thing you can do is use setTimeout correctly.

Replace this

 <button type="button" value=" Send" class="btn btn-success" type="submit" id="submit">

with

<button  value=" Send" class="btn btn-success" type="submit" id="submit">

As an update to Scott Munro's answer:

• In C# 6.0 and VB.NET 14.0 (VS 2015), either Environment.ExitCode or Environment.Exit(exitCode) is required to return an non-zero code from a console application. Changing the return type of Main has no effect.
• In F# 4.0 (VS 2015), the return value of the main entry point is respected.

I believe if a file is modified but not yet added (staged), it is purely "private".
Meaning it cannot be restored by GIT if overwritten with the index or the HEAD version (unless you have a copy of your current work somewhere).

A "private" content is one only visible in your current directory, but not registered in any way in Git.

Note: As explained in other answers, you can recover your changes if you use an IDE (with local history) or have an open editor (ctrl+Z).

Webkit browsers support the ability to add "stroke" to fonts. This bit of style makes fonts look thinner (assuming a white background):

-webkit-text-stroke: 2px white;

Example on codepen here: http://codepen.io/mackdoyle/pen/yrgEH Some people are using SVG for a cross-platform "stroke" solution: http://codepen.io/CrocoDillon/pen/dGIsK

I think that we can await for the value just returning first null and then get the real value, so in the case of Pure MVVM (PCL project for instance) I think the following is the most elegant solution:

private IEnumerable myList;
public IEnumerable MyList
{
  get
    { 
      if(myList == null)
         InitializeMyList();
      return myList;
     }
  set
     {
        myList = value;
        NotifyPropertyChanged();
     }
}

private async void InitializeMyList()
{
   MyList = await AzureService.GetMyList();
}

I also had this problem in my system, but after looking inside the project I saw the XML structure of the .classpath file in the project path was incorrect. After amending that file the problem was solved.

If you're looking for a space, that would be " " (one space).

If you're looking for one or more, it's " *" (that's two spaces and an asterisk) or " +" (one space and a plus).

If you're looking for common spacing, use "[ X]" or "[ X][ X]*" or "[ X]+" where X is the physical tab character (and each is preceded by a single space in all those examples).

These will work in every* regex engine I've ever seen (some of which don't even have the one-or-more "+" character, ugh).

If you know you'll be using one of the more modern regex engines, "\s" and its variations are the way to go. In addition, I believe word boundaries match start and end of lines as well, important when you're looking for words that may appear without preceding or following spaces.

For PHP specifically, this page may help.

From your edit, it appears you want to remove all non valid characters The start of this is (note the space inside the regex):

$newtag = preg_replace ("/[^a-zA-Z0-9 ]/", "", $tag);
#                                    ^ space here

If you also want trickery to ensure there's only one space between each word and none at the start or end, that's a little more complicated (and probably another question) but the basic idea would be:

$newtag = preg_replace ("/ +/", " ", $tag); # convert all multispaces to space
$newtag = preg_replace ("/^ /", "", $tag);  # remove space from start
$newtag = preg_replace ("/ $/", "", $tag);  # and end

I faced the same problem due to illegal spaces in my entire code.

I fixed it by selecting one of these spaces and use find and replace to replace all matches with regular spaces.

File -> Spreadsheet Settings -> (Tab) Calculation -> Recalculation (3 Options)
- On change
- On change and every minute
- On change and every hour
This affects how often NOW, TODAY, RAND, and RANDBETWEEN are updated.

but.. .. it updates only, if the functions arguments (their ranges, cells) are affected by that.
  

from my example
I use google spreadsheet to find out the age of a person. I have his birthday date in the format (dd.mm.yyyy) -> it's the used format here in Switzerland.

=ARRAYFORMULA(IF(ISTEXT(K4:K), IF(TODAY() - DATE(YEAR(TODAY()), MONTH(REGEXREPLACE(K4:K, "[.]", "/")), DAY(REGEXREPLACE(K4:K, "[.]", "/"))) > 0, YEAR(TODAY()) - YEAR(REGEXREPLACE(K4:K, "[.]", "/")) + 1, YEAR(TODAY()) - YEAR(REGEXREPLACE(K4:K, "[.]", "/"))), IF(LEN(K4:K) > 0, IF(TODAY() - DATE(YEAR(TODAY()), MONTH(K4:K), DAY(K4:K)) > 0, YEAR(TODAY()) - YEAR(K4:K) + 1, YEAR(TODAY()) - YEAR(K4:K)), "")))

I'm using TODAY() and I did the recalculation settings described above. -> but no automatically refresh. :-(
It updates only, if I change some value inside the ranges where the function is looking for.

So I wrote a Google Script (Tools -> Script Editor..) for that purpose.

function onOpen() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheetMaster = ss.getSheetByName("Master"); 
  var sortRange = sheetMaster.getRange(firstRow, firstColumn, lastRow, lastColumn);  

  sortRange.getCell(1, 2).setValue(sortRange.getCell(1, 2).getValue());
}

You need to set numbers for firstRow, firstColumn, lastRow, lastColumn

The Script get active when the spreadsheets open, writes the content of one cell into the same cell again. That's enough to trigger the TODAY() function.

Look for more information on that link from Edward Moffett. Force google sheet formula to recalculate

Best regards,
Christoph

What this means is that you are trying to print out/output a value which is at least partially uninitialized. Can you narrow it down so that you know exactly what value that is? After that, trace through your code to see where it is being initialized. Chances are, you will see that it is not being fully initialized.

If you need more help, posting the relevant sections of source code might allow someone to offer more guidance.

EDIT

I see you've found the problem. Note that valgrind watches for Conditional jump or move based on unitialized variables. What that means is that it will only give out a warning if the execution of the program is altered due to the uninitialized value (ie. the program takes a different branch in an if statement, for example). Since the actual arithmetic did not involve a conditional jump or move, valgrind did not warn you of that. Instead, it propagated the "uninitialized" status to the result of the statement that used it.

It may seem counterintuitive that it does not warn you immediately, but as mark4o pointed out, it does this because uninitialized values get used in C all the time (examples: padding in structures, the realloc() call, etc.) so those warnings would not be very useful due to the false positive frequency.

sing the CSS @import Rule here

@import url('/css/header.css') screen;
@import url('/css/content.css') screen;
@import url('/css/sidebar.css') screen;
@import url('/css/print.css') print;

Try excluding height from the style element.

i.e. neither give height:100% nor to any other value.

There is a direct method to find this out. And, it does not require the layout changes.
So it works in immersive fullscreen mode, too.
But, unfortunately, it does not work on all devices. So you have to test it with your device(s).

The trick is that you try to hide or show the soft keyboard and capture the result of that try.
If it works correct then the keyboard is not really shown or hidden. We just ask for the state.

To stay up-to-date, you simply repeat this operation, e.g. every 200 milliseconds, using a Handler.

The implementation below does just a single check.
If you do multiple checks, then you should enable all the (_keyboardVisible) tests.

public interface OnKeyboardShowHide
{
    void    onShowKeyboard( Object param );
    void    onHideKeyboard( Object param );
}

private static Handler      _keyboardHandler    = new Handler();
private boolean             _keyboardVisible    = false;
private OnKeyboardShowHide  _keyboardCallback;
private Object              _keyboardCallbackParam;

public void start( OnKeyboardShowHide callback, Object callbackParam )
{
    _keyboardCallback      = callback;
    _keyboardCallbackParam = callbackParam;
    //
    View view = getCurrentFocus();
    if (view != null)
    {
        InputMethodManager imm = (InputMethodManager) getSystemService( Activity.INPUT_METHOD_SERVICE );
        imm.hideSoftInputFromWindow( view.getWindowToken(), InputMethodManager.HIDE_IMPLICIT_ONLY, _keyboardResultReceiver );
        imm.showSoftInput( view, InputMethodManager.SHOW_IMPLICIT, _keyboardResultReceiver );
    }
    else // if (_keyboardVisible)
    {
        _keyboardVisible = false;
        _keyboardCallback.onHideKeyboard( _keyboardCallbackParam );
    }
}

private ResultReceiver      _keyboardResultReceiver = new ResultReceiver( _keyboardHandler )
{
    @Override
    protected void onReceiveResult( int resultCode, Bundle resultData )
    {
        switch (resultCode)
        {
            case InputMethodManager.RESULT_SHOWN :
            case InputMethodManager.RESULT_UNCHANGED_SHOWN :
                // if (!_keyboardVisible)
                {
                    _keyboardVisible = true;
                    _keyboardCallback.onShowKeyboard( _keyboardCallbackParam );
                }
                break;
            case InputMethodManager.RESULT_HIDDEN :
            case InputMethodManager.RESULT_UNCHANGED_HIDDEN :
                // if (_keyboardVisible)
                {
                    _keyboardVisible = false;
                    _keyboardCallback.onHideKeyboard( _keyboardCallbackParam );
                }
                break;
        }
    }
};

One thing I did to overcome this issue was to use a UIButton instead of a UILabel. Then in the Attributes Inspector of the Interface Builder, I used the Edge for the Title as the padding.
If you do not attach the button to an action, when clicked it will not get selected but it will still show the highlight.

You can also do this programmatically with the following code:

UIButton *mButton = [[UIButton alloc] init];
[mButton setTitleEdgeInsets:UIEdgeInsetsMake(top, left, bottom, right)];
[mButton setTitle:@"Title" forState:UIControlStateNormal];
[self.view addSubView:mButton];

This approach gives the same result but sometimes it did not work for some reason that I did not investigate since if possible I use the Interface Builder.

This is still a workaround but it works quite nicely if the highlight doesn't bother you. Hope it is useful

.style1 {

  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

Works in:

• Safari 3+
• Chrome Whatever+
• IE 9+
• Opera 10+ (Opera 9.5 supported background-size but not the keywords)
• Firefox 3.6+ (Firefox 4 supports non-vendor prefixed version)

In addition you can try this for an IE solution

-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='myBackground.jpg', sizingMethod='scale')";

    Console.WriteLine(Assembly.LoadFile(args).FullName);
    Console.WriteLine(Assembly.LoadFile(args).GetCustomAttributes(typeof(System.Runtime.Versioning.TargetFrameworkAttribute), false).SingleOrDefault());
    try {
        var assemblies = Assembly.LoadFile(args).GetReferencedAssemblies(); 

        if (assemblies.GetLength(0) > 0)

i generally use it as a LinqPad script you can call it as

DependencyInfo("@c:\MyAssembly.dll"); from the code

if you are using Maven 2.0.8+, then it will be very simple, run mvndebug from the console, and connect to it via Remote Debug Java Application with port 8000.

The free EclipseColorer Editor can do syntax highlighting for bash scripts.

However, It does not use Eclipse's "Outline view", i.e it does not fill it with a list of function definitions. Sometimes syntax highlighting just stops in the middle of the script. Then reopening the script helps.

As a side answer it's worth to note that:

• ARIA is commonly used to improve the accessibility for screen readers. (not only but mostly atm.)
• Using ARIA does not necessarily make things better! Easily ARIA can lead to significantly worse accessibility if not implemented and tested properly. Don't use ARIA just to have some "cool things in the code" which you don't fully understand. Sadly too often ARIA implementations introduce more issues than solutions in terms of accessibility. This is rather common since sighted users and developers are less likely to put extra effort in extensive testing with screen readers while on the other hand ARIA specs and validators are currently far from perfect and even confusing in some cases. On top of that each browser and screen reader implement the ARIA support non-uniformly causing the major inconsistencies in the behavior. Often it's better idea to avoid ARIA completely when it's not clear exactly what it does, how it behaves and it won't be tested intensively with all screen readers and browsers (or at least the most common combinations). Disclaimer: My intention is not to disgrace ARIA but rather its bad ARIA implementations. In fact it's not so uncommon that HTML5 don't offer any other alternatives where implementing ARIA would bring significant benefits for the accessibility e.g. aria-hidden or aria-expanded. But only if implemented and tested properly!

You can use a CASE statement...however why don't you just create a table with an integer for ages between 0 and 150, a varchar for the written out age and then you can just join on that

Global $myArr;
$myArr = array();

function someFuntion(){
    global $myArr;

    $myVal = //some processing here to determine value of $myVal
    $myArr[] = $myVal;
}

Be forewarned, generally people stick away from globals as it has some downsides.

You could try this

function someFuntion($myArr){
    $myVal = //some processing here to determine value of $myVal
    $myArr[] = $myVal;
    return $myArr;
}
$myArr = someFunction($myArr);

That would make it so you aren't relying on Globals.

And for now, here is https://github.com/google/go-cmp which

is intended to be a more powerful and safer alternative to reflect.DeepEqual for comparing whether two values are semantically equal.

package main

import (
    "fmt"

    "github.com/google/go-cmp/cmp"
)

func main() {
    a := []byte{1, 2, 3}
    b := []byte{1, 2, 3}

    fmt.Println(cmp.Equal(a, b)) // true
}

You can easily present Html.ActionLink as a button by using the appropriate CSS style. For example:

@Html.ActionLink("Save", "ActionMethod", "Controller", new { @class = "btn btn-primary" })

What is JSON?

JavaScript Object Notation (JSON) is a lightweight data-interchange format inspired by the object literals of JavaScript.

JSON values can consist of:

objects (collections of name-value pairs) arrays (ordered lists of values) strings (in double quotes) numbers true, false, or null

JSON is language independent.

JSON with PHP?

After PHP Version 5.2.0, JSON extension is decodes and encodes functionalities as default.

Json_encode - returns the JSON representation of values Json_decode - Decodes the JSON String Json_last_error - Returns the last error occured.

JSON Syntax and Rules?

JSON syntax is derived from JavaScript object notation syntax:

Data is in name/value pairs Data is separated by commas Curly braces hold objects Square brackets hold arrays

year(table_column)

Example:

select * from mytable where year(transaction_day)='2013' 

if not exists (select * from sysobjects where name='cars' and xtype='U')
    create table cars (
        Name varchar(64) not null
    )
go

The above will create a table called cars if the table does not already exist.

You might look at the code for the open source tool findimagedupes, though it appears to have been written in perl, so I can't say how easy it will be to parse...

Reading the findimagedupes page that I liked, I see that there is a C++ implementation of the same algorithm. Presumably this will be easier to understand.

And it appears you can also use gqview.
