If you change your html code a bit - remove the ids

<ul id='myid'>  
<li>First</li>
<li>Second</li>
<li>Third</li>
<li>Fourth</li>
<li>Fifth</li>
</ul>

Then the jquery code you want is...

$("#myid li").click(function() {
    alert($(this).prevAll().length+1);
});?

You don't need to place any ids, just keep on adding li items.

Take a look at demo

Useful links

• jQuery prevAll

Use InvokeOnClick event. it works even if the button is invisible/disabled

grep -c ^processor /proc/cpuinfo     

will count the number of lines starting with "processor" in /proc/cpuinfo

For systems with hyper-threading, you can use

grep ^cpu\\scores /proc/cpuinfo | uniq |  awk '{print $4}' 

which should return (for example) 8 (whereas the command above would return 16)

It just does it. It instantiates a and b, and injects each one into the other (using their setter methods).

What's the problem?

If the following conditions are true, then rewrite the URL:
If the requested filename is not a directory,

RewriteCond %{REQUEST_FILENAME} !-d

and if the requested filename is not a regular file that exists,

RewriteCond %{REQUEST_FILENAME} !-f

and if the requested filename is not a symbolic link,

RewriteCond %{REQUEST_FILENAME} !-l

then rewrite the URL in the following way:
Take the whole request filename and provide it as the value of a "url" query parameter to index.php. Append any query string from the original URL as further query parameters (QSA), and stop processing this .htaccess file (L).

RewriteRule ^(.+)$ index.php?url=$1 [QSA,L]

Apache docs #flag_qsa

Another Example:

RewriteRule "/pages/(.+)" "/page.php?page=$1" [QSA]

With the [QSA] flag, a request for

/pages/123?one=two

will be mapped to

/page.php?page=123&one=two

add Environment Path to

C:\Program Files\nodejs\node.exe;C:\Users[your username]\AppData\Roaming\npm

You can (although controverse) extend System.String to provide a case insensitive comparison extension method:

public static bool CIEquals(this String a, String b) {
    return a.Equals(b, StringComparison.CurrentCultureIgnoreCase);
}

and use as such:

x.Username.CIEquals((string)drUser["Username"]);

C# allows you to create extension methods that can serve as syntax suggar in your project, quite useful I'd say.

It's not the answer and I know this question is old and solved, I just wanted to add these bits.

this is the simplest code for doing this

public final void launchFacebook() {
        final String urlFb = "fb://page/"+yourpageid;
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setData(Uri.parse(urlFb));

        // If a Facebook app is installed, use it. Otherwise, launch
        // a browser
        final PackageManager packageManager = getPackageManager();
        List<ResolveInfo> list =
            packageManager.queryIntentActivities(intent,
            PackageManager.MATCH_DEFAULT_ONLY);
        if (list.size() == 0) {
            final String urlBrowser = "https://www.facebook.com/"+pageid;
            intent.setData(Uri.parse(urlBrowser));
        }

        startActivity(intent);
    }

My fix for my same problem: Adding the "other linker flags" in "Project" and not in "Targets". So, I moved it to "Targets", it shouldn't be in "Project".

Have you tried adding a magic comment in the script where you use non-ASCII chars? It should go on top of the script.

#!/bin/env ruby
# encoding: utf-8

It worked for me like a charm.

This code works for me: check this link
This is my code when i stop and start service in activity

case R.id.buttonStart:
  Log.d(TAG, "onClick: starting srvice");
  startService(new Intent(this, MyService.class));
  break;
case R.id.buttonStop:
  Log.d(TAG, "onClick: stopping srvice");
  stopService(new Intent(this, MyService.class));
  break;
}
}
 }

And in service class:

  @Override
public void onCreate() {
    Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
    Log.d(TAG, "onCreate");

    player = MediaPlayer.create(this, R.raw.braincandy);
    player.setLooping(false); // Set looping
}

@Override
public void onDestroy() {
    Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
    Log.d(TAG, "onDestroy");
    player.stop();
}

Sending and receiving data in JSON format using POST method

// Sending and receiving data in JSON format using POST method
//
var xhr = new XMLHttpRequest();
var url = "url";
xhr.open("POST", url, true);
xhr.setRequestHeader("Content-Type", "application/json");
xhr.onreadystatechange = function () {
    if (xhr.readyState === 4 && xhr.status === 200) {
        var json = JSON.parse(xhr.responseText);
        console.log(json.email + ", " + json.password);
    }
};
var data = JSON.stringify({"email": "[email protected]", "password": "101010"});
xhr.send(data);

Sending and receiving data in JSON format using GET method

// Sending a receiving data in JSON format using GET method
//      
var xhr = new XMLHttpRequest();
var url = "url?data=" + encodeURIComponent(JSON.stringify({"email": "[email protected]", "password": "101010"}));
xhr.open("GET", url, true);

Handling data in JSON format on the server-side using PHP

<?php
// Handling data in JSON format on the server-side using PHP
//
header("Content-Type: application/json");
// build a PHP variable from JSON sent using POST method
$v = json_decode(stripslashes(file_get_contents("php://input")));
// build a PHP variable from JSON sent using GET method
$v = json_decode(stripslashes($_GET["data"]));
// encode the PHP variable to JSON and send it back on client-side
echo json_encode($v);
?>

The limit of the length of an HTTP Get request is dependent on both the server and the client (browser) used, from 2kB - 8kB. The server should return 414 (Request-URI Too Long) status if an URI is longer than the server can handle.

Note Someone said that I could use state names instead of state values; in other words I could use xhr.readyState === xhr.DONE instead of xhr.readyState === 4 The problem is that Internet Explorer uses different state names so it's better to use state values.

I usually use the following approach

DECLARE @calls TABLE (
    id INT IDENTITY(1,1)
    ,parameter INT
    )

INSERT INTO @calls
select parameter from some_table where some_condition -- here you populate your parameters

declare @i int
declare @n int
declare @myId int
select @i = min(id), @n = max(id) from @calls
while @i <= @n
begin
    select 
        @myId = parameter
    from 
        @calls
    where id = @i

        EXECUTE p_MyInnerProcedure @myId
    set @i = @i+1
end

The number of itemIds in your list will be the same as the number of elements in your list:

int itemCount = list.size();

However, if you're looking to count the number of unique itemIds (per @pst) then you should use a set to keep track of them.

Set<String> itemIds = new HashSet<String>();

//...
itemId = p.getItemId();
itemIds.add(itemId);

//... later ...
int uniqueItemIdCount = itemIds.size();

If you don't want to use an EOF character for this, you can use StringTokenizer :

import java.util.*;
public class Test{
   public static void main(){
      Scanner sc = new Scanner (System.in);
      System.out.print("Enter your sentence: ");
      String s=sc.nextLine();
      StringTokenizer st=new StringTokenizer(s," ");//" " is the delimiter here.
      while (st.hasMoreTokens() ) {
        String s1 = st.nextToken();
        System.out.println(s1);
      }

      System.out.println("The loop has been ended");
   }
}

You are trying to write to system folders. With ADB you have root (admin) access so you see the system folders of which sdcard is one of them so to send a picture you could use

D:\Program Files\Android\sdk\platform-tools\adb push am files\android sdk\adb.exe push C:\Downloads\anand.jpg /sdcard/pictures/

NB: C:\Downloads\anand.jpg replace with path and name to picture..

You need to call GetResponse().

Stream receiveStream = response.GetResponseStream ();
StreamReader readStream = new StreamReader (receiveStream, Encoding.UTF8);
txtBlock.Text = readStream.ReadToEnd();

Adding something after # sets the focus of page to the element with that ID. Simplest solution is to use #/ even if you are using jQuery. However if you are handling the event in jQuery, event.preventDefault() is the way to go.

The command is date

To customise the output there are a myriad of options available, see date --help for a list.

For example, date '+%A %W %Y %X' gives Tuesday 34 2013 08:04:22 which is the name of the day of the week, the week number, the year and the time.

your_dict = {}

To add new key:

1. your_dict[key]=value

2. your_dict.update(key=value)

I suggest looking at this gcc page which discusses the tradeoffs between the "cfront" and "borland" model for template instantiations.

https://gcc.gnu.org/onlinedocs/gcc-4.6.4/gcc/Template-Instantiation.html

The "borland" model corresponds to what the author suggests, providing the full template definition, and having things compiled multiple times.

It contains explicit recommendations concerning using manual and automatic template instantiation. For example, the "-repo" option can be used to collect templates which need to be instantiated. Or another option is to disable automatic template instantiations using "-fno-implicit-templates" to force manual template instantiation.

In my experience, I rely on the C++ Standard Library and Boost templates being instantiated for each compilation unit (using a template library). For my large template classes, I do manual template instantiation, once, for the types I need.

This is my approach because I am providing a working program, not a template library for use in other programs. The author of the book, Josuttis, works a lot on template libraries.

If I was really worried about speed, I suppose I would explore using Precompiled Headers https://gcc.gnu.org/onlinedocs/gcc/Precompiled-Headers.html

which is gaining support in many compilers. However, I think precompiled headers would be difficult with template header files.

Option 1. Use Visual Basic to iterate through each column and format each column as Text.

Use the Text-to-Columns menu, don't change the delimination, and change "General" to "Text"

or Just %~F will give you the full path and full file name.

For example, if you want to register all *.ax files in the current directory....

FOR /R C:. %F in (*.ax) do regsvr32 "%~F"

This works quite nicely in Win7 (64bit) :-)

Check whether your template in theme folder contains search.php and searchform.php or not.

gcc -I/path -L/path

• -I /path path to include, gcc will find .h files in this path

• -L /path contains library files, .a, .so

When you add floating point numbers together, there's often a little bit of error. Would a range(0.0, 2.2, 1.1) return [0.0, 1.1] or [0.0, 1.1, 2.199999999]? There's no way to be certain without rigorous analysis.

The code you posted is an OK work-around if you really need this. Just be aware of the possible shortcomings.

As second says, most of the "design" decisions made for TeX documents are backed up by well researched usability studies, so changing them should be undertaken with care. It is, however, relatively common to replace Computer Modern with Times (also a serif face).

Try \usepackage{times}.

[\W_]+

$string = preg_replace("/[\W_]+/u", '', $string);

It select all not A-Z, a-z, 0-9 and delete it.

See example here: https://regexr.com/3h1rj

For Left indent Shift + Tab

For Right indent simple Tab

It actually depends on what is being used to print the result. Usually, the result is the same, just as you say -

Historically carriage return is supposed to do about what the home button does: return the caret to the start of the line.

\n is supposed to give you a new line but not move the caret.

If you think about old printers, you're pretty much thinking how the original authors of the character sets were thinking. It's a different operation moving the paper feeder and moving the caret. These two characters express that difference.

To get or set an attribute of an HTML element, you can use the element.attr() function in jQuery.

To get the href attribute, use the following code:

var a_href = $('selector').attr('href');

To set the href attribute, use the following code:

$('selector').attr('href','http://example.com');

In both cases, please use the appropriate selector. If you have set the class for the anchor element, use '.class-name' and if you have set the id for the anchor element, use '#element-id'.

tl;dr

String cleanString = dirtyString.strip() ; // Call new `String::string` method.

String::strip…

The old String::trim method has a strange definition of whitespace.

As discussed here, Java 11 adds new strip… methods to the String class. These use a more Unicode-savvy definition of whitespace. See the rules of this definition in the class JavaDoc for Character::isWhitespace.

Example code.

String input = " some Thing ";
System.out.println("before->>"+input+"<<-");
input = input.strip();
System.out.println("after->>"+input+"<<-");

Or you can strip just the leading or just the trailing whitespace.

You do not mention exactly what code point(s) make up your newlines. I imagine your newline is likely included in this list of code points targeted by strip:

• It is a Unicode space character (SPACE_SEPARATOR, LINE_SEPARATOR, or PARAGRAPH_SEPARATOR) but is not also a non-breaking space ('\u00A0', '\u2007', '\u202F').
• It is '\t', U+0009 HORIZONTAL TABULATION.
• It is '\n', U+000A LINE FEED.
• It is '\u000B', U+000B VERTICAL TABULATION.
• It is '\f', U+000C FORM FEED.
• It is '\r', U+000D CARRIAGE RETURN.
• It is '\u001C', U+001C FILE SEPARATOR.
• It is '\u001D', U+001D GROUP SEPARATOR.
• It is '\u001E', U+001E RECORD SEPARATOR.
• It is '\u001F', U+0

The -H 'Cache-Control: no-cache' argument is not guaranteed to work because the remote server or any proxy layers in between can ignore it. If it doesn't work, you can do it the old-fashioned way, by adding a unique querystring parameter. Usually, the servers/proxies will think it's a unique URL and not use the cache.

curl "http://www.example.com?foo123"

You have to use a different querystring value every time, though. Otherwise, the server/proxies will match the cache again. To automatically generate a different querystring parameter every time, you can use date +%s, which will return the seconds since epoch.

curl "http://www.example.com?$(date +%s)"

You can do it with a table, like this:

<table width="100%">
  <tr>
    <td style="width: 50%">Left Text</td>
    <td style="width: 50%; text-align: right;">Right Text</td>
  </tr>
</table>

Or, you can do it with CSS like this:

<div style="float: left;">
    Left text
</div>
<div style="float: right;">
    Right text
</div>

You should read Learn Prolog Now! Chapter 10.2 Using Cut. This provides an example:

max(X,Y,Z) :- X =< Y,!, Y = Z.

to be said,

Z is equal to Y IF ! is true (which it always is) AND X is <= Y.

Found this solution using PdfRenderer.

https://medium.com/@chahat.jain0/rendering-a-pdf-document-in-android-activity-fragment-using-pdfrenderer-442462cb8f9a

Like that:

class Zoo {
    AnimalClass: typeof Animal;

    constructor(AnimalClass: typeof Animal ) {
        this.AnimalClass = AnimalClass
        let Hector = new AnimalClass();
    }
}

Or just:

class Zoo {
    constructor(public AnimalClass: typeof Animal ) {
        let Hector = new AnimalClass();
    }
}

typeof Class is the type of the class constructor. It's preferable to the custom constructor type declaration because it processes static class members properly.

Here's the relevant part of TypeScript docs. Search for the typeof. As a part of a TypeScript type annotation, it means "give me the type of the symbol called Animal" which is the type of the class constructor function in our case.

This prints it in the console:

echo %cd%

or paste this command in CMD, then you'll have pwd:

(echo @echo off
echo echo ^%cd^%) > C:\WINDOWS\pwd.bat

I am not experiented .But i think XmlReader is unnecessary. It is very hard to use.
XElement is very easy to use.
If you need performance ( faster ) you must change file format and use StreamReader and StreamWriter classes.

Hope this will help !

I was looking for the same thing and I've just seen that MySQL 5.6 has a couple of new string functions supporting this functionality: TO_BASE64 and FROM_BASE64.

First thing,

Properties class is based on Hashtable and not Hashmap. Properties class basically extends Hashtable

There is no such constructor in HashMap class which takes a properties object and return you a hashmap object. So what you are doing is NOT correct. You should be able to cast the object of properties to hashtable reference.

All you need is a ADODB.Connection

Dim cnn As ADODB.Connection ' Requieres reference to the
Dim rs As ADODB.Recordset   ' Microsoft ActiveX Data Objects Library

Set cnn = CreateObject("adodb.Connection")
cnn.Open "DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=C:\Access\webforums\whiteboard2003.mdb;"

Set rs = cnn.Execute(SQLQuery) ' Retrieve the data

Method 1 : Using jQuery Ajax Get call (partial page update).

Suitable for when you need to retrieve jSon data from database.

Controller's Action Method

[HttpGet]
public ActionResult Foo(string id)
{
    var person = Something.GetPersonByID(id);
    return Json(person, JsonRequestBehavior.AllowGet);
}

Jquery GET

function getPerson(id) {
    $.ajax({
        url: '@Url.Action("Foo", "SomeController")',
        type: 'GET',
        dataType: 'json',
        // we set cache: false because GET requests are often cached by browsers
        // IE is particularly aggressive in that respect
        cache: false,
        data: { id: id },
        success: function(person) {
            $('#FirstName').val(person.FirstName);
            $('#LastName').val(person.LastName);
        }
    });
}

Person class

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Method 2 : Using jQuery Ajax Post call (partial page update).

Suitable for when you need to do partial page post data into database.

Post method is also same like above just replace [HttpPost] on Action method and type as post for jquery method.

For more information check Posting JSON Data to MVC Controllers Here

Method 3 : As a Form post scenario (full page update).

Suitable for when you need to save or update data into database.

View

@using (Html.BeginForm("SaveData","ControllerName", FormMethod.Post))
{        
    @Html.TextBoxFor(model => m.Text)
    
    <input type="submit" value="Save" />
}

Action Method

[HttpPost]
public ActionResult SaveData(FormCollection form)
    {
        // Get movie to update
        return View();
   }

Method 4 : As a Form Get scenario (full page update).

Suitable for when you need to Get data from database

Get method also same like above just replace [HttpGet] on Action method and FormMethod.Get for View's form method.

I hope this will help to you.

I also like to wrap session variables in properties. The setters here are trivial, but I like to write the get methods so they have only one exit point. To do that I usually check for null and set it to a default value before returning the value of the session variable. Something like this:

string Name
{
   get 
   {
       if(Session["Name"] == Null)
           Session["Name"] = "Default value";
       return (string)Session["Name"];
   }
   set { Session["Name"] = value; }
}

}

I found an excellent utility that is configurable at https://github.com/acch/genfiles.

It fills the target file with random data, so there are no problems with sparse files, and for my purposes (testing compression algorithms) it gives a nice level of white noise.

FYI you can sometimes use SYSTEM or Trustedinstaller to kill tasks ;)

google quickkill_3_0.bat

sc config TrustedInstaller binPath= "cmd /c TASKKILL /F  /IM notepad.exe
sc start "TrustedInstaller"

Here is a handy variation that makes use of InputStream.transferTo() from Java 9, and OutputStream.nullOutputStream() from Java 11. It requires no external libraries and does not need to load the entire file into memory.

public static String hashFile(String algorithm, File f) throws IOException, NoSuchAlgorithmException {
    MessageDigest md = MessageDigest.getInstance(algorithm);

    try(BufferedInputStream in = new BufferedInputStream((new FileInputStream(f)));
        DigestOutputStream out = new DigestOutputStream(OutputStream.nullOutputStream(), md)) {
        in.transferTo(out);
    }

    String fx = "%0" + (md.getDigestLength()*2) + "x";
    return String.format(fx, new BigInteger(1, md.digest()));
}

and

hashFile("SHA-512", Path.of("src", "test", "resources", "some.txt").toFile());

returns

"e30fa2784ba15be37833d569280e2163c6f106506dfb9b07dde67a24bfb90da65c661110cf2c5c6f71185754ee5ae3fd83a5465c92f72abd888b03187229da29"

I know this thread is about EditPad Pro, but I came here because I had the same need with a javascript regexp.

For the people who are here needing the same tip, you can use a function or lambda as the replace argument.

I use the function below to convert css names with - to the javascript equivalent, for example, "border-top" will be transformed into "borderTop":

    s = s.replace(/\-[a-z]/g, x => x[1].toUpperCase());

Since Java 7 you can use the static method java.util.Objects.equals(Object, Object) to perform equals checks on two objects without caring about them being null.

If both objects are null it will return true, if one is null and another isn't it will return false. Otherwise it will return the result of calling equals on the first object with the second as argument.

Every derived table (AKA sub-query) must indeed have an alias. I.e. each query in brackets must be given an alias (AS whatever), which can the be used to refer to it in the rest of the outer query.

SELECT ID FROM (
    SELECT ID, msisdn FROM (
        SELECT * FROM TT2
    ) AS T
) AS T

In your case, of course, the entire query could be replaced with:

SELECT ID FROM TT2

Apache's commons.collections library has a CollectionUtils class that provides easy-to-use methods for Collection manipulation/checking, such as intersection, difference, and union.

The org.apache.commons.collections.CollectionUtils API docs are here.

A real problem often exists because any variables set inside will not be exported when that batch file finishes. So its not possible to export, which caused us issues. As a result, I just set the registry to ALWAYS used delayed expansion (I don't know why it's not the default, could be speed or legacy compatibility issue.)

Easy and better than str_replace:

<?php
$arr = array(
    "http://" => "http://www.",
    "w" => "W",
    "d" => "D");

    $word = "http://desiweb.ir";
    echo strtr($word,$arr);
?>

Changing the tab order should be all it takes to accomplish this. Keep it simple.

Another simple option would be to put the back button after the submit button in the HTML code but float it to the left so it appears on the page before the submit button.

You have to perform the GridView1.Columns[i].Visible = false; after the grid has been databound.

This is the format of /etc/crontab:

# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  * user-name  command to be executed

I recommend copy & pasting that into the top of your crontab file so that you always have the reference handy. RedHat systems are setup that way by default.

To run something every minute:

* * * * * username /var/www/html/a.php

To run something at midnight of every day:

0 0 * * * username /var/www/html/reset.php

You can either include /usr/bin/php in the command to run, or you can make the php scripts directly executable:

chmod +x file.php

Start your php file with a shebang so that your shell knows which interpreter to use:

#!/usr/bin/php
<?php
// your code here

select id, group_concat(`Name` separator ',') as `ColumnName`
from
(
  select 
    id, 
    concat(`Name`, ':', group_concat(`Value` separator ',')) as `Name`
  from mytbl
  group by 
    id, 
    `Name`
) tbl
group by id;

You can see it implemented here : Sql Fiddle Demo. Exactly what you need.

Update Splitting in two steps. First we get a table having all values(comma separated) against a unique[Name,id]. Then from obtained table we get all names and values as a single value against each unique id See this explained here SQL Fiddle Demo (scroll down as it has two result sets)

Edit There was a mistake in reading question, I had grouped only by id. But two group_contacts are needed if (Values are to be concatenated grouped by Name and id and then over all by id). Previous answer was

select 
id,group_concat(concat(`name`,':',`value`) separator ',')
as Result from mytbl group by id

You can see it implemented here : SQL Fiddle Demo

PROBLEM RESOLVED

In my case the problem was that I do the ajax call (with $.ajax, $.get or $.getJSON methods from jQuery) with full path in the url param:

url: "http://mydomain.com/site/cgi-bin/serverApp.php"

But the correct way is to pass the value of url as:

url: "site/cgi-bin/serverApp.php"

Some browser don't conflict and make no distiction between one text or another, but in Firefox 3.6 for Mac OS take this full path as "cross site scripting"... another thing, in the same browser there is a distinction between:

http://mydomain.com/site/index.html

And put

http://www.mydomain.com/site/index.html

In fact it is the correct point view, but most implementations make no distinction, so the solution was to remove all the text that specify the full path to the script in the methods that do the ajax request AND.... remove any BASE tag in the index.html file

base href="http://mydomain.com/" <--- bad idea, remove it!

If you don't remove it, this version of browser for this system may take your ajax request like if it is a cross site request!

I have the same problem but only on the Mac OS machine. The problem is that Firefox treat the ajax response as an "cross site" call, in any other machine/browser it works fine. I didn't found any help about this (I think that is a firefox implementation issue), but I'm going to prove the next code at the server side:

header('Content-type: application/json');

to ensure that browser get the data as "json data" ...

A pointer can receive a NULL parameter, a reference parameter can not. If there's ever a chance that you could want to pass "no object", then use a pointer instead of a reference.

Also, passing by pointer allows you to explicitly see at the call site whether the object is passed by value or by reference:

// Is mySprite passed by value or by reference?  You can't tell 
// without looking at the definition of func()
func(mySprite);

// func2 passes "by pointer" - no need to look up function definition
func2(&mySprite);

I wouldn't have thought so.

If you have Visual Studio you could edit them through that. Some versions of Visual Studio has Crystal Reports shipped with them.

If not, you will have to find someone who has Crystal Reports and ask then nicely to amend them for you. Or buy Crystal Reports!

I'm not 100% sure if this is the answer, but its the trick i use to simulate the CSS :hover effect with colours and images inline.

`This works best with an image`

class TestHover extends React.PureComponent {
render() {
const landingImage = {     
"backgroundImage": "url(https://i.dailymail.co.uk/i/pix/2015/09/01/18/2BE1E88B00000578-3218613-image-m-5_1441127035222.jpg)",
"BackgroundColor": "Red", `this can be any color`
"minHeight": "100%",
"backgroundAttachment": "fixed",
"backgroundPosition": "center",
"backgroundRepeat": "no-repeat",
"backgroundSize": "cover", 
"opacity": "0.8", `the hove trick is here in the opcaity slightly see through gives the effect when the background color changes`
    }

  return (
    <aside className="menu">
        <div className="menu-item">
          <div style={landingImage}>SOME TEXT</div>
        </div>
    </aside>
      ); 
  }
}
ReactDOM.render(
    <TestHover />,
  document.getElementById("root")
);

CSS:

.menu {
top: 2.70em;
bottom: 0px;
width: 100%;
position: absolute;
}

.menu-item {
cursor: pointer;
height: 100%;
font-size: 2em;
line-height: 1.3em;
color: #000;
font-family: "Poppins";
font-style: italic;
font-weight: 800;
text-align: center;
display: flex;
flex-direction: column;
justify-content: center;
}

Before hover

.menu-item:nth-child(1) {
color: white;
background-color: #001b37;
} 

On hover

.menu-item:nth-child(1):hover {
color: green;
background-color: white;
}

If you're using glib, then you can use g_file_get_contents;

gchar *contents;
GError *err = NULL;

g_file_get_contents ("foo.txt", &contents, NULL, &err);
g_assert ((contents == NULL && err != NULL) || (contents != NULL && err == NULL));
if (err != NULL)
  {
    // Report error to user, and free error
    g_assert (contents == NULL);
    fprintf (stderr, "Unable to read file: %s\n", err->message);
    g_error_free (err);
  }
else
  {
    // Use file contents
    g_assert (contents != NULL);
  }
}

It is also possible to open the pdf link in a new window and let the browser handle the rest:

window.open(pdfUrl, '_blank');

or:

window.open(pdfUrl);

I did the following to solve the mentioned problem. I got the mentioned problem when I was trying to run the built exe, even I successfully built the exe using pyinstaller. I did this on Windows 10.

1. go to https://pypi.org/project/six/#files
2. download "six-1.14.0.tar.gz (33.9 kB)"
3. unzip it, copy and paste "six.py" into your source directory.
4. import "six" module into your source code (import six)
5. run source script.

I know that this question is accepted and has a bit of age but this might be helpful for some people who still find it relevant. Although the outcome is not a full RESTful API the API Builder mini lib for PHP allows you to easily transform MySQL databases into web accessible JSON APIs.

As noted by VonC, this has already been included in git 2.16+. Unfortunately, the name of the option (--ignore-cr-at-eol) differs from the one used by GNU diff that I'm used to (--strip-trailing-cr).

When I was confronted with this problem, my solution was to invoke GNU diff instead of git's built-in diff, because my git is older than 2.16. I did that using this command line:

GIT_EXTERNAL_DIFF='diff -u --strip-trailing-cr "$2" "$5";true;#' git diff --ext-diff

That allows using --strip-trailing-cr and any other GNU diff options.

There's also this other way:

git difftool -y -x 'diff -u --strip-trailing-cr'

but it doesn't use the configured pager settings, which is why I prefer the former.

Try this

function test()
{
   $("body").append("<input type='button' id='field' />");
}

I had a similar issue and what I did is: Create a array of Buttons

Button buttons[] = new Button[10];

Then to implement on click listener and reference xml id's I used a loop like this

for (int i = 0; i < 10; i++) {      
String buttonID = "button" + i;
        int resID = getResources().getIdentifier(buttonID, "id",
                "your package name here");
        buttons[i] = (Button) findViewById(resID);
        buttons[i].setOnClickListener(this);
    }

But calling them up remains same as in Prag's answer point 4. PS- If anybody has a better method to call up all the button's onClick, please do comment.

If a vector has N elements, there are N+1 possible answers for find. std::find and std::find_if return an iterator to the found element OR end() if no element is found. To change the code as little as possible, your find function should return the equivalent position:

size_t find( const vector<type>& where, int searchParameter )
{
   for( size_t i = 0; i < where.size(); i++ ) {
       if( conditionMet( where[i], searchParameter ) ) {
           return i;
       }
    }
    return where.size();
}
// caller:
const int position = find( firstVector, parameter );
if( position != secondVector.size() ) {
    doAction( secondVector[position] );
}

I would still use std::find_if, though.

JConsole can do it. Also you can use a powerful jvisualVM tool, which also is included in JDK since 1.6.0.8.

SELECT MAX("field name") AS ("primary key") FROM ("table name")

example:

SELECT MAX(brand) AS brandid FROM brand_tbl

Other answers here seem to favor omitting the trailing slash. There is one case in which a trailing slash will help with search engine optimization (SEO). That is the case that your document has what appears to be a file extension that is not .html. This becomes an issue with sites that are rating websites. They might choose between these two urls:

• http://mysite.example.com/rated.example.com
• http://mysite.example.com/rated.example.com/

In such a case, I would choose the one with the trailing slash. That is because the .com extension is an extension for Windows executable command files. Search engines and virus checkers often dislike URLs that appear that they may contain malware distributed through such mechanisms. The trailing slash seems to mitigate any concerns, allowing the page to rank in search engines and get by virus checkers.

If your URLs have no . in the file portion, then I would recommend omitting the trailing slash for simplicity.

1. Click BUILD > Configuration Manager...
2. Under Project contexts > Configuration, select "Release"
3. BUILD > Build Solution or Rebuild Solution

I got the answer.

grep -rl matchstring somedir/ | xargs sed -i 's/string1/string2/g'

The first parameter to the iterator in forEach is the value and second is the key of the object.

angular.forEach(objectToIterate, function(value, key) {
    /* do something for all key: value pairs */
});

In your example, the outer forEach is actually:

angular.forEach($scope.filters, function(filterObj , filterKey)

You have to call the function you want to be called on load (i.e., load of the document/page). For example, the function you want to load when document or page load is called "yourFunction". This can be done by calling the function on load event of the document. Please see the code below for more detail.

Try the code below:

<script src="js/jquery-1.11.0.min.js" type="text/javascript"></script>
<script type="text/javascript">

    $(document).ready(function () {
        yourFunction();
    });
    function yourFunction(){
      //some code
    }
</script>

is it possible to extend query results with literals like this?

Yes.

Select Name
From Customers
UNION ALL
Select 'Jason'

• Use UNION to add Jason if it isn't already in the result set.
• Use UNION ALL to add Jason whether or not he's already in the result set.

There is no other way to do it other than what you described. Think about it - how can anyone know what classes extend ClassX without scanning each class on the classpath?

Eclipse can only tell you about the super and subclasses in what seems to be an "efficient" amount of time because it already has all of the type data loaded at the point where you press the "Display in Type Hierarchy" button (since it is constantly compiling your classes, knows about everything on the classpath, etc).

We can simply use Collections.max() and Collections.min() method.

public class MaxList {
    public static void main(String[] args) {
        List l = new ArrayList();
        l.add(1);
        l.add(2);
        l.add(3);
        l.add(4);
        l.add(5);
        System.out.println(Collections.max(l)); // 5
        System.out.println(Collections.min(l)); // 1
    }
}

if ($.inArray('example', myArray) != -1)
{
  // found it
}

You can do it by using window_handles and switch_to_window method.

Before clicking the link first store the window handle as

window_before = driver.window_handles[0]

after clicking the link store the window handle of newly opened window as

window_after = driver.window_handles[1]

then execute the switch to window method to move to newly opened window

driver.switch_to_window(window_after)

and similarly you can switch between old and new window. Following is the code example

import unittest
from selenium import webdriver

class GoogleOrgSearch(unittest.TestCase):

    def setUp(self):
        self.driver = webdriver.Firefox()

    def test_google_search_page(self):
        driver = self.driver
        driver.get("http://www.cdot.in")
        window_before = driver.window_handles[0]
        print window_before
        driver.find_element_by_xpath("//a[@href='http://www.cdot.in/home.htm']").click()
        window_after = driver.window_handles[1]
        driver.switch_to_window(window_after)
        print window_after
        driver.find_element_by_link_text("ATM").click()
        driver.switch_to_window(window_before)

    def tearDown(self):
        self.driver.close()

if __name__ == "__main__":
    unittest.main()

There's another explanation for why .env doesn't exist, and it happens when you move all the Laravel files.

Take this workflow: in your project directory you do laravel new whatever, Laravel is installed in whatever, you do mv * .. to move all the files to your project folder, and you remove whatever. The problem is, mv doesn't move hidden files by default, so the .env files are left behind, and are removed!

If $a is the array that's passed, $a[76][0]['id'] should give '76' and $a[76][1]['id'] should give '81', but I can't test as I don't have PHP installed on this machine.

I've found an easy way to export query results from SQL Server Management Studio 2005 to Excel.

1) Select menu item Query -> Query Options.

2) Set check box in Results -> Grid -> Include column headers when copying or saving the results.

After that, when you Select All and Copy the query results, you can paste them to Excel, and the column headers will be present.

Try:

With DependencedIncidents AS
(
    SELECT INC.[RecTime],INC.[SQL] AS [str] FROM
    (
        SELECT A.[RecTime] As [RecTime],X.[SQL] As [SQL] FROM [EventView] AS A 
        CROSS JOIN [Incident] AS X
            WHERE
                patindex('%' + A.[Col] + '%', X.[SQL]) > 0
    ) AS INC
),
lalala AS
(
    SELECT INC.[RecTime],INC.[SQL] AS [str] FROM
    (
        SELECT A.[RecTime] As [RecTime],X.[SQL] As [SQL] FROM [EventView] AS A 
        CROSS JOIN [Incident] AS X
            WHERE
                patindex('%' + A.[Col] + '%', X.[SQL]) > 0
    ) AS INC
)

And yes, you can reference common table expression inside common table expression definition. Even recursively. Which leads to some very neat tricks.

I was looking for a list multiplied by itself with only unique combinations, which is provided as this function.

import itertools
itertools.combinations(list, n_times)

Here as an excerpt from the Python docs on itertools That might help you find what your looking for.

Combinatoric generators:

Iterator                                 | Results

                                         |   nested for-loop
-----------------------------------------+----------------------------------------
permutations(p[, r])                     | r-length tuples, all possible 
                                         |   orderings, no repeated elements

is it good to use async action everywhere in ASP.NET MVC?

As usual in programming, it depends. There is always a trade-off when going down a certain path.

async-await shines in places where you know you'll receiving concurrent requests to your service and you want to be able to scale out well. How does async-await help with scaling out? In the fact that when you invoke a async IO call synchronously, such as a network call or hitting your database, the current thread which is responsible for the execution is blocked waiting for the request to finish. When you use async-await, you enable the framework to create a state machine for you which makes sure that after the IO call is complete, your method continues executing from where it left off.

A thing to note is that this state machine has a subtle overhead. Making a method asynchronous does not make it execute faster, and that is an important factor to understand and a misconception many people have.

Another thing to take under consideration when using async-await is the fact that it is async all the way, meaning that you'll see async penetrate your entire call stack, top to buttom. This means that if you want to expose synchronous API's, you'll often find yourself duplicating a certain amount of code, as async and sync don't mix very well.

Shall I use async/await keywords when I want to query database (via EF/NHibernate/other ORM)?

If you choose to go down the path of using async IO calls, then yes, async-await will be a good choice, as more and more modern database providers expose async method implementing the TAP (Task Asynchronous Pattern).

How many times I can use await keywords to query database asynchronously in ONE single action method?

As many as you want, as long as you follow the rules stated by your database provider. There is no limit to the amount of async calls you can make. If you have queries which are independent of each other and can be made concurrently, you can spin a new task for each and use await Task.WhenAll to wait for both to complete.

An object can't be null - the value of an expression can be null. It's worth making the difference clear in your mind. The value of s isn't an object - it's a reference, which is either null or refers to an object.

And yes, you should just use

if (s == null)

Note that this will still use the overloaded == operator defined in string, but that will do the right thing.

It seems some what center of the screen. So I would like to do like this

body { 
     background: url('http://oi44.tinypic.com/33tjudk.jpg') no-repeat center center fixed;    
     background-size:cover; 
     text-align: 0 auto; // Make the play button horizontal center
}

#play_button {
    position:absolute;  // absolutely positioned
    transition: .5s ease;
    top: 50%;  // Makes vertical center
} 

you need to use display = none

value hidden is connected with attributet called visibility

so your code should look like this

<script type="text/javascript">
function hide(){
document.getElementById("test").style.display="none";
}
</script>

A simple and clean way: use np.argwhere to group the indices by element, rather than dimension as in np.nonzero(a) (i.e., np.argwhere returns a row for each non-zero element).

>>> a = np.arange(10)
>>> a
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
>>> np.argwhere(a>4)
array([[5],
       [6],
       [7],
       [8],
       [9]])

np.argwhere(a) is the same as np.transpose(np.nonzero(a)).

Note: You cannot use a(np.argwhere(a>4)) to get the corresponding values in a. The recommended way is to use a[(a>4).astype(bool)] or a[(a>4) != 0] rather than a[np.nonzero(a>4)] as they handle 0-d arrays correctly. See the documentation for more details. As can be seen in the following example, a[(a>4).astype(bool)] and a[(a>4) != 0] can be simplified to a[a>4].

Another example:

>>> a = np.array([5,-15,-8,-5,10])
>>> a
array([  5, -15,  -8,  -5,  10])
>>> a > 4
array([ True, False, False, False,  True])
>>> a[a > 4]
array([ 5, 10])
>>> a = np.add.outer(a,a)
>>> a
array([[ 10, -10,  -3,   0,  15],
       [-10, -30, -23, -20,  -5],
       [ -3, -23, -16, -13,   2],
       [  0, -20, -13, -10,   5],
       [ 15,  -5,   2,   5,  20]])
>>> a = np.argwhere(a>4)
>>> a
array([[0, 0],
       [0, 4],
       [3, 4],
       [4, 0],
       [4, 3],
       [4, 4]])
>>> [print(i,j) for i,j in a]
0 0
0 4
3 4
4 0
4 3
4 4

For forms, use the [FromForm] attribute instead of the [FromBody] attribute.

The below controller works with ASP.NET Core 1.1:

public class MyController : Controller
{
    [HttpPost]
    public async Task<IActionResult> Submit([FromForm] MyModel model)
    {
        //...
    }
}

Note: [FromXxx] is required if your controller is annotated with [ApiController]. For normal view controllers it can be omitted.

var array = Encoding.ASCII.GetBytes(new string(' ', 100));

I found that for me the best permanent solution to stay up-to-date under Linux was to install the R-patched project. This will keep your R installation up-to-date, and you needn't even move your packages between installations (which is described in RyanStochastic's answer).

For openSUSE, see the instructions here.

Your return is useless if you don't assign it

list=defineAList()

You need a program that learns and improves classification accuracy organically from experience.

I'll suggest deep learning, with deep learning this becomes a trivial problem.

You can retrain the inception v3 model on Tensorflow:

How to Retrain Inception's Final Layer for New Categories.

In this case, you will be training a convolutional neural network to classify an object as either a coca-cola can or not.

Many modern browsers now support ES6 modules. As long as you import your scripts (including the entrypoint to your application) using <script type="module" src="..."> it will work.

Take a look at caniuse.com for more details: https://caniuse.com/#feat=es6-module

Having the AVD android emulator:

1. Open the simulator ( "..\android-sdk\AVD Manager.exe")
2. Go to Tools

Jupyter under the WinPython environment has a batch file in the scripts folder called:

make_working_directory_be_not_winpython.bat

You need to edit the following line in it:

echo WINPYWORKDIR = %%HOMEDRIVE%%%%HOMEPATH%%\Documents\WinPython%%WINPYVER%%\Notebooks>>"%winpython_ini%"

replacing the Documents\WinPython%%WINPYVER%%\Notebooks part with your folder address.

Notice that the %%HOMEDRIVE%%%%HOMEPATH%%\ part will identify the root and user folders (i.e. C:\Users\your_name\) which will allow you to point different WinPython installations on separate computers to the same cloud storage folder (e.g. OneDrive) where you could store, access, and work with the same files from different machines. I find that very useful.

The way I would do it is to leave the __ init__.py files empty, and do:

import lib.mod1.mod11
lib.mod1.mod11.mod12()

or

from lib.mod1.mod11 import mod12
mod12()

You may find that the mod1 dir is unnecessary, just have mod12.py in lib.

The new django.urls.path() function allows a simpler, more readable URL routing syntax. For example, this example from previous Django releases:

url(r'^articles/(?P<year>[0-9]{4})/$', views.year_archive)

could be written as:

path('articles/<int:year>/', views.year_archive)

The django.conf.urls.url() function from previous versions is now available as django.urls.re_path(). The old location remains for backwards compatibility, without an imminent deprecation. The old django.conf.urls.include() function is now importable from django.urls so you can use:

from django.urls import include, path, re_path

in the URLconfs. For further reading django doc

curl -s http://google.com > temp.html

works for curl version 7.19.5 on Ubuntu 9.10 (no progress bar). But if for some reason that does not work on your platform, you could always redirect stderr to /dev/null:

curl  http://google.com 2>/dev/null > temp.html

Set the window start style as maximized. Then, hide the minimize and maximize buttons.

Could use CASE WHEN to leave those with no ';' alone.

    SELECT
    CASE WHEN CHARINDEX(';', MyText) > 0 THEN
    LEFT(MyText, CHARINDEX(';', MyText)-1) ELSE
    MyText END
    FROM MyTable

It depends on how your $('site-header') is constructed.

You can try to use $timeout with 0 delay. Something like:

return function(scope, element, attrs) {
    $timeout(function(){
        $('.main').height( $('.site-header').height() -  $('.site-footer').height() );
    });        
}

Explanations how it works: one, two.

Don't forget to inject $timeout in your directive:

.directive('sticky', function($timeout)

The reason your attempt wasn't working, is because the two animations (fade-in and fade-out) were working against each other.

Right before an object became visible, it was still invisible and so the animation for fading-out would run. Then, the fraction of a second later when that same object had become visible, the fade-in animation would try to run, but the fade-out was still running. So they would work against each other and you would see nothing.

Eventually the object would become visible (most of the time), but it would take a while. And if you would scroll down by using the arrow-button at the button of the scrollbar, the animation would sort of work, because you would scroll using bigger increments, creating less scroll-events.

Enough explanation, the solution (JS, CSS, HTML):

$(window).on("load",function() {_x000D_
  $(window).scroll(function() {_x000D_
    var windowBottom = $(this).scrollTop() + $(this).innerHeight();_x000D_
    $(".fade").each(function() {_x000D_
      /* Check the location of each desired element */_x000D_
      var objectBottom = $(this).offset().top + $(this).outerHeight();_x000D_
      _x000D_
      /* If the element is completely within bounds of the window, fade it in */_x000D_
      if (objectBottom < windowBottom) { //object comes into view (scrolling down)_x000D_

• I wrapped the fade-codeline in an if-clause: if ($(this).css("opacity")==0) {...}. This makes sure the object is only faded in when the opacity is 0. Same goes for fading out. And this prevents the fade-in and fade-out from working against each other, because now there's ever only one of the two running at one time on an object.
• I changed .animate() to .fadeTo(). It's jQuery's specialized function for opacity, a lot shorter to write and probably lighter than animate.
• I changed .position() to .offset(). This always calculates relative to the body, whereas position is relative to the parent. For your case I believe offset is the way to go.
• I changed $(window).height() to $(window).innerHeight(). The latter is more reliable in my experience.
• Directly after the scroll-handler, I invoke that handler once on page-load with $(window).scroll();. Now you can give all desired objects on the page the .fade class, and objects that should be invisible at page-load, will be faded out immediately.
• I removed #container from both HTML and CSS, because (at least for this answer) it isn't necessary. (I thought maybe you needed the height:2000px because you used .position() instead of .offset(), otherwise I don't know. Feel free of course to leave it in your code.)

UPDATE

If you want opacity values other than 0 and 1, use the following code:

$(window).on("load",function() {_x000D_
  function fade(pageLoad) {_x000D_
    var windowBottom = $(window).scrollTop() + $(window).innerHeight();_x000D_
    var min = 0.3;_x000D_
    var max = 0.7;_x000D_
    var threshold = 0.01;_x000D_
    _x000D_
    $(".fade").each(function() {_x000D_
      /* Check the location of each desired element */_x000D_
      var objectBottom = $(this).offset().top + $(this).outerHeight();_x000D_
      _x000D_
      /* If the element is completely within bounds of the window, fade it in */_x000D_
      if (objectBottom < windowBottom) { //object comes into view (scrolling down)_x000D_
        if ($(this).css("opacity")<=min+threshold || pageLoad) {$(this).fadeTo(500,max);}_x000D_
      } else { //object goes out of view (scrolling up)_x000D_
        if ($(this).css("opacity")>=max-threshold || pageLoad) {$(this).fadeTo(500,min);}_x000D_
      }_x000D_
    });_x000D_
  } fade(true); //fade elements on page-load_x000D_
  $(window).scroll(function(){fade(false);}); //fade elements on scroll_x000D_
});

.fade {_x000D_
  margin: 50px;_x000D_
  padding: 50px;_x000D_
  background-color: lightgreen;_x000D_
  opacity: 1;_x000D_
}

• I added a threshold to the if-clause, see explanation below.
• I created variables for the threshold and for min/max at the start of the function. In the rest of the function these variables are referenced. This way, if you ever want to change the values again, you only have to do it in one place.
• I also added || pageLoad to the if-clause. This was necessary to make sure all objects are faded to the correct opacity on page-load. pageLoad is a boolean that is send along as an argument when fade() is invoked.
  I had to put the fade-code inside the extra function fade() {...}, in order to be able to send along the pageLoad boolean when the scroll-handler is invoked.
  I did't see any other way to do this, if anyone else does, please leave a comment.

Explanation:
The reason the code in your fiddle didn't work, is because the actual opacity values are always a little off from the value you set it to. So if you set the opacity to 0.3, the actual value (in this case) is 0.300000011920929. That's just one of those little bugs you have to learn along the way by trail and error. That's why this if-clause won't work: if ($(this).css("opacity") == 0.3) {...}.

I added a threshold, to take that difference into account: == 0.3 becomes <= 0.31.
(I've set the threshold to 0.01, this can be changed of course, just as long as the actual opacity will fall between the set value and this threshold.)

The operators are now changed from == to <= and >=.

UPDATE 2:

If you want to fade the elements based on their visible percentage, use the following code:

$(window).on("load",function() {_x000D_
  function fade(pageLoad) {_x000D_
    var windowTop=$(window).scrollTop(), windowBottom=windowTop+$(window).innerHeight();_x000D_
    var min=0.3, max=0.7, threshold=0.01;_x000D_
    _x000D_
    $(".fade").each(function() {_x000D_
      /* Check the location of each desired element */_x000D_
      var objectHeight=$(this).outerHeight(), objectTop=$(this).offset().top, objectBottom=$(this).offset().top+objectHeight;_x000D_
      _x000D_
      /* Fade element in/out based on its visible percentage */_x000D_
      if (objectTop < windowTop) {_x000D_
        if (objectBottom > windowTop) {$(this).fadeTo(0,min+((max-min)*((objectBottom-windowTop)/objectHeight)));}_x000D_
        else if ($(this).css("opacity")>=min+threshold || pageLoad) {$(this).fadeTo(0,min);}_x000D_
      } else if (objectBottom > windowBottom) {_x000D_
        if (objectTop < windowBottom) {$(this).fadeTo(0,min+((max-min)*((windowBottom-objectTop)/objectHeight)));}_x000D_
        else if ($(this).css("opacity")>=min+threshold || pageLoad) {$(this).fadeTo(0,min);}_x000D_
      } else if ($(this).css("opacity")<=max-threshold || pageLoad) {$(this).fadeTo(0,max);}_x000D_
    });_x000D_
  } fade(true); //fade elements on page-load_x000D_
  $(window).scroll(function(){fade(false);}); //fade elements on scroll_x000D_
});

.fade {_x000D_
  margin: 50px;_x000D_
  padding: 50px;_x000D_
  background-color: lightgreen;_x000D_
  opacity: 1;_x000D_

I know this is old and there are so many answers, some are really convoluted, can be quick and inline:

<asp:Button runat="server" ID="btnUserDelete" Text="Delete" CssClass="GreenLightButton" OnClick="BtnUserDelete_Click" OnClientClick="return confirm('Are you sure you want to delete this user?');" meta:resourcekey="BtnUserDeleteResource1" />
                       

run npm install jquery --save

then on your root component, place this

global.jQuery = require('../node_modules/jquery/dist/jquery.js');
var $ = global.jQuery;

Do not forget to export it to enable you to use it with other components

export default {
  name: 'App',
  components: {$}
}

You can use the ansible.cfg file, it should look like this (There are other parameters which you might want to include):

[defaults]
inventory = <PATH TO INVENTORY FILE>
remote_user = <YOUR USER>
private_key_file =  <PATH TO KEY_FILE>

Hope this saves you some typing

See the answer 'favorite bit of code' that works

Here is how I used it:

     // Delete all rows from the WebLog table via the EF database context object
    // using a where clause that returns an IEnumerable typed list WebLog class 
    public IEnumerable<WebLog> DeleteAllWebLogEntries()
    {
        IEnumerable<WebLog> myEntities = context.WebLog.Where(e => e.WebLog_ID > 0);
        context.WebLog.RemoveRange(myEntities);
        context.SaveChanges();

        return myEntities;
    }

Here in my sample I find out the solution of this, because I had the same problem with updates and subquerys:

UPDATE
    A
SET
    A.ValueToChange = B.NewValue
FROM
    (
        Select * From C
    ) B
Where 
    A.Id = B.Id

For the auto-reconnect issue with DBCP, has any tried using the following 2 configuration parameters?

validationQuery="Some Query"

testOnBorrow=true

You can try this way

 String input = "";
 try {
   int x = Integer.parseInt(input); 
   // You can use this method to convert String to int, But if input 
   //is not an int  value then this will throws NumberFormatException. 
   System.out.println("Valid input");
 }catch(NumberFormatException e) {
   System.out.println("input is not an int value"); 
   // Here catch NumberFormatException
   // So input is not a int.
 } 

If you mean the screen where you have that interpreter prompt >>> you can do CTRL+L on Bash shell can help. Windows does not have equivalent. You can do

import os
os.system('cls')  # on windows

or

os.system('clear')  # on linux / os x

You need to close the connection before you can use the output parameters. Something like this

con.Close();
MessageBox.Show(cmd.Parameters["@code"].Value.ToString());

Write this;

 SELECT f from Student f LEFT JOIN f.classTbls s WHERE s.ClassName = 'abc'

Because your Student entity has One To Many relationship with ClassTbl entity.

As far that I know you only can get time with Date.

Date.now is the solution but is not available everywhere : https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date/now.

var currentTime = +new Date();

This gives you the current time in milliseconds.

For your jumps. If you compute interpolations correctly according to the delta frame time and you don't have some rounding number error, I bet for the garbage collector (GC).

If there is a lot of created temporary object in your loop, garbage collection has to lock the thread to make some cleanup and memory re-organization.

With Chrome you can see how much time the GC is spending in the Timeline panel.

EDIT: Since my answer, Date.now() should be considered as the best option as it is supported everywhere and on IE >= 9.

You have not specified the version, I'm assuming you are using Powershell v3.

Try this:

$path = "C:\Users\abc\Desktop\File\abc.txt"
(Get-Content $path -Raw).Replace("`r`n","`n") | Set-Content $path -Force

^{Editor's note: As mike z points out in the comments, Set-Content appends a trailing CRLF, which is undesired. Verify with: 'hi' > t.txt; (Get-Content -Raw t.txt).Replace("`r`n","`n") | Set-Content t.txt; (Get-Content -Raw t.txt).EndsWith("`r`n"), which yields $True.}

Note this loads the whole file in memory, so you might want a different solution if you want to process huge files.

UPDATE

This might work for v2 (sorry nowhere to test):

$in = "C:\Users\abc\Desktop\File\abc.txt"
$out = "C:\Users\abc\Desktop\File\abc-out.txt"
(Get-Content $in) -join "`n" > $out

^{Editor's note: Note that this solution (now) writes to a different file and is therefore not equivalent to the (still flawed) v3 solution. (A different file is targeted to avoid the pitfall Ansgar Wiechers points out in the comments: using > truncates the target file before execution begins). More importantly, though: this solution too appends a trailing CRLF, which may be undesired. Verify with 'hi' > t.txt; (Get-Content t.txt) -join "`n" > t.NEW.txt; [io.file]::ReadAllText((Convert-Path t.NEW.txt)).endswith("`r`n"), which yields $True.}

Same reservation about being loaded to memory though.

I installed mavaen using sdkman because of which the other proposed solution didn't work, as they are applicable if the installation is done via Homebrew or as a standalone binary.

for my solution I did "which mvn" in the terminal which returned: "/Users/samkaz/.sdkman/candidates/maven/current/bin/mvn"

Then after opening the path in a finder and looking around the above directory I found settings.xml in the below folder. "/Users/samkaz/.sdkman/candidates/maven/3.6.3/conf"

According way you create your user, MySQL interprets a different manner. For instance, if you create a user like this:

create user user01 identified by 'test01';

MySQL expects you give some privilege using grant all on <your_db>.* to user01;

Don't forget to flush privileges;

But, if you create user like that (by passing an IP address), you have to change it to:

create user 'user02'@'localhost' identified by 'teste02';

so, to give some privileges you have to do that:

grant all on <your_db>.* to user02@localhost;
flush privileges;

The PowerShell is almost exactly the same.

    var str = this;

    for(var latin in removalMap) {
      var nonLatin = removalMap[latin];
      str = str.replace(nonLatin , latin);
    }

    return str;
}

It uses real chars instead of unicode list and works well.

You can use it like

"aaa".removeAccents(); // returns "aaa"

You can easily convert this function to not be string prototype. However, as I'm fan of using string prototype in such cases, you'll have to do it yourself.

I always use this

ctx.clearRect(0, 0, canvas.width, canvas.height)
window.requestAnimationFrame(functionToBeCalled)

NOTE

combining clearRect and requestAnimationFrame allows for more fluid animation if that is what you're going for

hibernate3.HibernateQueryException: Books is not mapped [SELECT COUNT(*) FROM Books];

Hibernate is trying to say that it does not know an entity named "Books". Let's look at your entity:

@javax.persistence.Entity
@javax.persistence.Table(name = "Books")
public class Book {

Right. The table name for Book has been renamed to "Books" but the entity name is still "Book" from the class name. If you want to set the entity name, you should use the @Entity annotation's name instead:

// this allows you to use the entity Books in HQL queries
@javax.persistence.Entity(name = "Books")
public class Book {

That sets both the entity name and the table name.

The opposite problem happened to me when I was migrating from the Person.hbm.xml file to using the Java annotations to describe the hibernate fields. My old XML file had:

<hibernate-mapping package="...">
    <class name="Person" table="persons" lazy="true">
       ...
</hibernate-mapping>

And my new entity had a @Entity(name=...) which I needed to set the name of the table.

// this renames the entity and sets the table name
@javax.persistence.Entity(name = "persons")
public class Person {
    ...

What I then was seeing was HQL errors like:

QuerySyntaxException: Person is not mapped
     [SELECT id FROM Person WHERE id in (:ids)]

The problem with this was that the entity name was being renamed to persons as well. I should have set the table name using:

// no name = here so the entity can be used as Person
@javax.persistence.Entity
// table name specified here
@javax.persistence.Table(name = "persons")
public class Person extends BaseGeneratedId {

Hope this helps others.

you can try :

$("#MediaPlayer").ready(function(){
    $("html, body").delay(2000).animate({
        scrollTop: $('#MediaPlayer').offset().top 
    }, 2000);
});

While it's probably not the correct way to do it, something that I've found to be a simple workaround is to simply use a box-shadow rather than a border... This doesn't break the grid system. For example, in your case:

HTML

<div class="container">
    <div class="row" >
        <div class="span12">
            <div class="row">

We can do it nicely using Interceptors. You dont have to set options in all your services neither manage all your error responses, just define 2 interceptors (one to do something before sending the request to server and one to do something before sending the server's response to your service)

1. Define an AuthInterceptor class to do something before sending the request to the server. You can set the api token (retrieve it from localStorage, see step 4) and other options in this class.
2. Define an responseInterceptor class to do something before sending the server response to your service (httpClient). You can manage your server response, the most comon use is to check if the user's token is valid (if not clear token from localStorage and redirect to login).

3. In your app.module import HTTP_INTERCEPTORS from '@angular/common/http'. Then add to your providers the interceptors (AuthInterceptor and responseInterceptor). Doing this your app will consider the interceptors in all our httpClient calls.

4. At login http response (use http service), save the token at localStorage.

5. Then use httpClient for all your apirest services.

It seems that this symbol is rather obsolete now and the way it is processed may be(?) implementation dependent. At least for me your code gives the following output (xcode gcc 4.2, gdb console):

I got confused by this also. There are two commands relevant here:

docker run Run a command in a new container

docker start Start one or more stopped containers

I can offer you a jquery solution

add this in your <head></head> tag

<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.2.min.js"></script>

add this after </ul>

 <script> $('ul li:first').remove(); </script> 

You may use Socket for this like

String host = "www.yourhost.com";
Socket socket = new Socket(host, 80);
String request = "GET / HTTP/1.0\r\n\r\n";
OutputStream os = socket.getOutputStream();
os.write(request.getBytes());
os.flush();

InputStream is = socket.getInputStream();
int ch;
while( (ch=is.read())!= -1)
    System.out.print((char)ch);
socket.close();

The key is to use the command sudo update-java-alternatives -s java-6-sun. Any commands that rely on javac will be affected and not just Maven.

When you encounter exceptions like this, the most useful information is generally at the bottom of the stacktrace:

Caused by: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
  at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
  ...
  at org.apache.tomcat.jdbc.pool.PooledConnection.connectUsingDriver(PooledConnection.java:246)

The problem is that Tomcat can't find com.mysql.jdbc.Driver. This is usually caused by the JAR containing the MySQL driver not being where Tomcat expects to find it (namely in the webapps/<yourwebapp>/WEB-INF/lib directory).

the -v option for curl is too verbose in the error output which contains the leading *(status line) or >(request head field) or <(response head field). to get only the request head field:

curl -v -sS www.stackoverflow.com 2>&1 >/dev/null | grep '>' | cut -c1-2 --complement

to get only the request head field:

curl -v -sS www.stackoverflow.com 2>&1 >/dev/null | grep '<' | cut -c1-2 --complement

or to dump it into /tmp/test.txt file with the -D option

curl -D /tmp/test.txt -sS www.stackoverflow.com > /dev/null

in order to filter the -v output, you should direct the error output to terminal and the std output to /dev/null, the -s option is to forbid the progress metering

If your code must run under Python2 and Python3, use the 2to3 six library like this:

import six

six.next(g)  # on PY2K: 'g.next()' and onPY3K: 'next(g)'

I ran into this issue as well. My fix was to create a child schema. See below for an example for your models.

---- Person model

const mongoose = require('mongoose');
const SingleFriend = require('./SingleFriend');
const Schema   = mongoose.Schema;

const productSchema = new Schema({
  friends    : [SingleFriend.schema]
});

module.exports = mongoose.model('Person', personSchema);

***Important: SingleFriend.schema -> make sure to use lowercase for schema

--- Child schema

const mongoose = require('mongoose');
const Schema   = mongoose.Schema;

const SingleFriendSchema = new Schema({
  Name: String
});

module.exports = mongoose.model('SingleFriend', SingleFriendSchema);

As @Josh said, the correct answer is:

int column = 0,
    row = 0,
    index = 0;

You'll need to watch out for the same thing with pointers. This:

int* a, b, c;

Is equivalent to:

int *a;
int b;
int c;

IMHO the coolest way is to go via WebDAV (without Network Folder, as this is often not permitted). This can be accomplished via ActiveX Data Objects as layed out in this excellent article excellent article (code can be used directly in Excel, used the concept recently).

Standard Subversion layout

Create a git clone of that includes your Subversion trunk, tags, and branches with

git svn clone http://svn.example.com/project -T trunk -b branches -t tags

The --stdlayout option is a nice shortcut if your Subversion repository uses the typical structure:

git svn clone http://svn.example.com/project --stdlayout

Make your git repository ignore everything the subversion repo does:

git svn show-ignore >> .git/info/exclude

You should now be able to see all the Subversion branches on the git side:

git branch -r

Say the name of the branch in Subversion is waldo. On the git side, you'd run

git checkout -b waldo-svn remotes/waldo

The -svn suffix is to avoid warnings of the form

warning: refname 'waldo' is ambiguous.

To update the git branch waldo-svn, run

git checkout waldo-svn
git svn rebase

Starting from a trunk-only checkout

To add a Subversion branch to a trunk-only clone, modify your git repository's .git/config to contain

[svn-remote "svn-mybranch"]
        url = http://svn.example.com/project/branches/mybranch
        fetch = :refs/remotes/mybranch

You'll need to develop the habit of running

git svn fetch --fetch-all

to update all of what git svn thinks are separate remotes. At this point, you can create and track branches as above. For example, to create a git branch that corresponds to mybranch, run

git checkout -b mybranch-svn remotes/mybranch

For the branches from which you intend to git svn dcommit, keep their histories linear!

Further information

You may also be interested in reading an answer to a related question.

Without knowing your compiler, no one can give you specific, step by step instructions, but the basic procedure is as follows:

1. Specify the path which should be searched in order to find the actual library (usually under Library Search Paths, Library Directories, etc. in the properties page)

2. Under linker options, specify the actual name of the library. In VS, you would write Allegro.lib (or whatever it is), on Linux you usually just write Allegro (prefixes/suffixes are added automatically in most cases). This is usually under "Libraries->Input", just "Libraries", or something similar.

3. Ensure that you have included the headers for the library and make sure that they can be found (similar process to that listed in step #1 and #2). If it is a static library, you should be good; if it's a DLL, you need to copy it in your project.

4. Mash the build button.

ob_start();  // turns on output buffering
$foo->bar();  // all output goes only to buffer
ob_clean();  // delete the contents of the buffer, but remains buffering active
$foo->render(); // output goes to buffer
ob_flush(); // send buffer output
$none = ob_get_contents();  // buffer content is now an empty string
ob_end_clean();  // turn off output buffering

Buffers can be nested, so while one buffer is active, another ob_start() activates a new buffer. So ob_end_flush() and ob_flush() are not really sending the buffer to the output, but to the parent buffer. And only when there is no parent buffer, contents is sent to browser or terminal.

Nicely explained here: https://phpfashion.com/everything-about-output-buffering-in-php

This is just a warning.

Fixing

This occurs when the default configuration files log4j.properties and log4j.xml can not be found and the application performs no explicit configuration.

To fix that, simply create/copy log4j.properties or log4j.xml into your a location on the classpath (usually the same as the jar files).

Optionally set java option: -Dlog4j.configuration=file:///path/to/log4j.properties.

log4j uses Thread.getContextClassLoader().getResource() to locate the default configuration files and does not directly check the file system. Knowing the appropriate location to place log4j.properties or log4j.xml requires understanding the search strategy of the class loader in use. log4j does not provide a default configuration since output to the console or to the file system may be prohibited in some environments.

Debugging

For debugging, you may try to use -Dlog4j.debug=true parameter.

Configuration of log4j.properties

Sample configuration of log4j.properties:

# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=DEBUG, A1

# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender

# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

# Print only messages of level WARN or above in the package com.foo.
log4j.logger.com.foo=WARN

Here is another configuration file that uses multiple appenders:

log4j.rootLogger=debug, stdout, R

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=example.log

log4j.appender.R.MaxFileSize=100KB
# Keep one backup file
log4j.appender.R.MaxBackupIndex=1

log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n

Apache Solr

If using Solr, copy <solr>/example/resources/log4j.properties into a location on the classpath.

Sample configuration of log4j.properties from Solr goes like:

#  Logging level
solr.log=logs/
log4j.rootLogger=INFO, file, CONSOLE

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender

log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%-4r [%t] %-5p %c %x \u2013 %m%n

#- size rotation with log cleanup.
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.MaxFileSize=4MB
log4j.appender.file.MaxBackupIndex=9

#- File to log to and log format
log4j.appender.file.File=${solr.log}/solr.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%-5p - %d{yyyy-MM-dd HH:mm:ss.SSS}; %C; %m\n

log4j.logger.org.apache.zookeeper=WARN
log4j.logger.org.apache.hadoop=WARN

# set to INFO to enable infostream log messages
log4j.logger.org.apache.solr.update.LoggingInfoStream=OFF

This simple cli will also work:

ls -1t | head -1

You may change the -1 to the number of files you want to list

Instead of downloading curl, down libcurl.

curl is just the application, libcurl is what you need for your C++ program

You can use the unicode of a non breaking space :

p:before { content: "\00a0 "; }

Background Image from API in swift 4 (with Kingfisher) :

import UIKit
import Kingfisher

extension UIView {

func addBackgroundImage(imgUrl: String, placeHolder: String){
    let backgroundImage = UIImageView(frame: self.bounds)
    backgroundImage.kf.setImage(with: URL(string: imgUrl), placeholder: UIImage(named: placeHolder))
    backgroundImage.contentMode = UIViewContentMode.scaleAspectFill
    self.insertSubview(backgroundImage, at: 0)

}
}

Usage:

someview.addBackgroundImage(imgUrl: "yourImgUrl", placeHolder: "placeHolderName")

My case it solved i was using

@Html.DropDownList(model => model.TypeId ...)  

using

@Html.DropDownListFor(model => model.TypeId ...) 

will solve it

best solution TNX to Drew Chapin and all of you too:

I just want to add that if you don't inheritently know the name of a domain controller, you can get the closest one, pass it's hostname to the -Server argument.

$dc = Get-ADDomainController -DomainName example.com -Discover -NextClosestSite

Get-ADUser -Server $dc.HostName[0] `
    -Filter { EmailAddress -Like "*Smith_Karla*" } `
    -Properties EmailAddress

my script:

$dc = Get-ADDomainController -DomainName example.com -Discover -NextClosestSite
 Get-ADUser -Server $dc.HostName[0] ` -Filter { EmailAddress -Like "*Smith_Karla*" } `  -Properties EmailAddress | Export-CSV "C:\Scripts\Email.csv

Structure in C

First you need to declare your structure:

struct mystruct{
 char element_1,
 char element_2
};

Instantiate C structure

Once you declared your structure , you can instantiate a variable that has as type your structure using either:

mystruct struct_example;

or :

mystruct* struct_example;

For the first use case you can access the varaiable eleemnet using the following syntax: struct_example.element_1 = 5;

For the second use case which is having a pointer to variable of type your structure, to be able to access the variable structure you need an arrow:

struct_example->element_1 = 5;

You can directly set the content type like below:

res.writeHead(200, {'Content-Type': 'text/plain'});

Playing an audio file ensures full background Javascript performance for the time being

For me, it was the simplest and least intrusive solution - apart from playing a faint / almost-empty sound, there are no other potential side effects

You can find the details here: https://stackoverflow.com/a/51191818/914546

(From other answers, I see that some people use different properties of the Audio tag, I do wonder whether it's possible to use the Audio tag for full performance, without actually playing something)

URL -- Uniform Resource Locator

Contains information about how to fetch a resource from its location. For example:

• http://example.com/mypage.html
• ftp://example.com/download.zip
• mailto:[email protected]
• file:///home/user/file.txt
• http://example.com/resource?foo=bar#fragment
• /other/link.html (A relative URL, only useful in the context of another URL)

URLs always start with a protocol (http) and usually contain information such as the network host name (example.com) and often a document path (/foo/mypage.html). URLs may have query parameters and fragment identifiers.

URN -- Uniform Resource Name

Identifies a resource by name. It always starts with the prefix urn: For example:

• urn:isbn:0451450523 to identify a book by its ISBN number.
• urn:uuid:6e8bc430-9c3a-11d9-9669-0800200c9a66 a globally unique identifier
• urn:publishing:book - An XML namespace that identifies the document as a type of book.

URNs can identify ideas and concepts. They are not restricted to identifying documents. When a URN does represent a document, it can be translated into a URL by a "resolver". The document can then be downloaded from the URL.

URI -- Uniform Resource Identifier

URIs encompasses both URLs, URNs, and other ways to indicate a resource.

An example of a URI that is neither a URL nor a URN would be a data URI such as data:,Hello%20World. It is not a URL or URN because the URI contains the data. It neither names it, nor tells you how to locate it over the network.

There are also uniform resource citations (URCs) that point to meta data about a document rather than to the document itself. An example of a URC would be an indicator for viewing the source code of a web page: view-source:http://example.com/. A URC is another type of URI that is neither URL nor URN.

Frequently Asked Questions

I've heard that I shouldn't say URL anymore, why?

The w3 spec for HTML says that the href of an anchor tag can contain a URI, not just a URL. You should be able to put in a URN such as <a href="urn:isbn:0451450523">. Your browser would then resolve that URN to a URL and download the book for you.

Do any browsers actually know how to fetch documents by URN?

Not that I know of, but modern web browser do implement the data URI scheme.

Can a URI be both a URL and a URN?

Good question. I've seen lots of places on the web that state this is true. I haven't been able to find any examples of something that is both a URL and a URN. I don't see how it is possible because a URN starts with urn: which is not a valid network protocol.

Does the difference between URL and URI have anything to do with whether it is relative or absolute?

No. Both relative and absolute URLs are URLs (and URIs.)

Does the difference between URL and URI have anything to do with whether it has query parameters?

No. Both URLs with and without query parameters are URLs (and URIs.)

Does the difference between URL and URI have anything to do with whether it has a fragment identifier?

No. Both URLs with and without fragment identifiers are URLs (and URIs.)

Is a tel: URI a URL or a URN?

For example tel:1-800-555-5555. It doesn't start with urn: and it has a protocol for reaching a resource over a network. It must be a URL.

But doesn't the w3C now say that URLs and URIs are the same thing?

Yes. The W3C realized that there is a ton of confusion about this. They issued a URI clarification document that says that it is now OK to use URL and URI interchangeably. It is no longer useful to strictly segment URIs into different types such as URL, URN, and URC.

The important point is that the list comprehension creates a new list. The generator creates a an iterable object that will "filter" the source material on-the-fly as you consume the bits.

Imagine you have a 2TB log file called "hugefile.txt", and you want the content and length for all the lines that start with the word "ENTRY".

So you try starting out by writing a list comprehension:

logfile = open("hugefile.txt","r")
entry_lines = [(line,len(line)) for line in logfile if line.startswith("ENTRY")]

This slurps up the whole file, processes each line, and stores the matching lines in your array. This array could therefore contain up to 2TB of content. That's a lot of RAM, and probably not practical for your purposes.

So instead we can use a generator to apply a "filter" to our content. No data is actually read until we start iterating over the result.

logfile = open("hugefile.txt","r")
entry_lines = ((line,len(line)) for line in logfile if line.startswith("ENTRY"))

Not even a single line has been read from our file yet. In fact, say we want to filter our result even further:

long_entries = ((line,length) for (line,length) in entry_lines if length > 80)

Still nothing has been read, but we've specified now two generators that will act on our data as we wish.

Lets write out our filtered lines to another file:

outfile = open("filtered.txt","a")
for entry,length in long_entries:
    outfile.write(entry)

Now we read the input file. As our for loop continues to request additional lines, the long_entries generator demands lines from the entry_lines generator, returning only those whose length is greater than 80 characters. And in turn, the entry_lines generator requests lines (filtered as indicated) from the logfile iterator, which in turn reads the file.

So instead of "pushing" data to your output function in the form of a fully-populated list, you're giving the output function a way to "pull" data only when its needed. This is in our case much more efficient, but not quite as flexible. Generators are one way, one pass; the data from the log file we've read gets immediately discarded, so we can't go back to a previous line. On the other hand, we don't have to worry about keeping data around once we're done with it.

SELECT  Priority, COALESCE(cnt, 0)
FROM    (
        SELECT  1 AS Priority
        UNION ALL
        SELECT  2 AS Priority
        UNION ALL
        SELECT  3 AS Priority
        UNION ALL
        SELECT  4 AS Priority
        UNION ALL
        SELECT  5 AS Priority
        ) p
LEFT JOIN
        (
        SELECT  Priority, COUNT(*) AS cnt
        FROM    jobs
        GROUP BY
                Priority
        ) j
ON      j.Priority = p.Priority

For print session data you do not need to use print_r() function every time .

If you use it then it will be non-readable format.Data will be looks very dirty.

But if you use my function all you have to do is to use p()-Funtion and pass data into it. //create new file into application/cms_helper.php and load helper cms into //autoload or on controller

/*Copy Code for p function from here and paste into cms_helper.php in application/helpers folder */

   //@parram $data-array,$d-if true then die by default it is false
   //@author Your name

    function p($data,$d = false){

          echo "<pre>"; 
             print_r($data);
          echo "</pre>"; 

        if($d == TRUE){
             die();
          } 
      }

Just remember to load cms_helper into your project or controller using $this->load->helper('cms'); use bellow code into your controller or model it will works just GREAT.

 p($this->session->all_userdata()); // it will apply pre to your sesison data and other array as  well

I also encountered that problem.Check if database name already exist in Mysql,and rename the old one.

Here is a list of special characters that you can escape when creating a string literal for JSON:

\b  Backspace (ASCII code 08)
\f  Form feed (ASCII code 0C)
\n  New line
\r  Carriage return
\t  Tab
\v  Vertical tab
\'  Apostrophe or single quote
\"  Double quote
\\  Backslash character

Reference: String literals

Some of these are more optional than others. For instance, your string should be perfectly valid whether you escape the tab character or leave in a tab literal. You should certainly be handling the backslash and quote characters, though.

One more solution as PyV8 seems to be unmaintained and dependent on the old version of libv8.

PyMiniRacer It's a wrapper around the v8 engine and it works with the new version and is actively maintained.

pip install py-mini-racer

from py_mini_racer import py_mini_racer
ctx = py_mini_racer.MiniRacer()
ctx.eval("""
function escramble_758(){
    var a,b,c
    a='+1 '
    b='84-'
    a+='425-'
    b+='7450'
    c='9'
    return a+c+b;
}
""")
ctx.call("escramble_758")

And yes, you have to replace document.write with return as others suggested

#include <stdio.h>

#define QUOTEME(x) #x

#ifndef TEST_FUN
#  define TEST_FUN func_name
#  define TEST_FUN_NAME QUOTEME(TEST_FUN)
#endif

int main(void)
{
    puts(TEST_FUN_NAME);
    return 0;
}

This should work:

select * from mytable where 'Journal'=ANY(pub_types);

i.e. the syntax is <value> = ANY ( <array> ). Also notice that string literals in postresql are written with single quotes.

This is how i do : 1) create an app.py in Sublime Text or Pycharm, or whatever the ide, and in that app.py have this code

from flask import Flask

app = Flask(__name__)

@app.route('/')
def helloWorld():
    return'<h1>Hello!</h1>' 

This is a very basic program to printout a hello , to test flask is working.I would advise to create app.py in a new folder, then locate where the folder is on command prompt enter image description here type in these line of codes on command prompt

>py -m venv env
>env\Scripts\activate
>pip install flask

Then

>set FLASK_APP=app.py
>flask run

Then press enter all will work
The name of my file is app.py, give the relevant name as per your file in code line

set FLASK_APP=app.py

Also if your python path is not set, in windows python is in AppData folder its hidden, so first have to view it and set the correct path under environment variables. This is how you reach environment variables
Control panel ->> system and security ->> system ->> advanced system setting Then in system properties you get environment variables

OK the main difference between class methods and static methods is:

• class method has its own identity, that's why they have to be called from within an INSTANCE.
• on the other hand static method can be shared between multiple instances so that it must be called from within THE CLASS

Try following example it works !!!

Use [Handler] in onCreate() method which makes use of postDelayed() method that Causes the Runnable to be added to the message queue, to be run after the specified amount of time elapses that is 0 in given example. 1

Refer this code :

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
       setContentView(R.layout.main);
    //------------------
    //------------------
    android.os.Handler customHandler = new android.os.Handler();
            customHandler.postDelayed(updateTimerThread, 0);
}

private Runnable updateTimerThread = new Runnable()
{
        public void run()
        {
            //write here whaterver you want to repeat
            customHandler.postDelayed(this, 1000);
        }
};

I found a very weird thing in Java today, so it goes like -

If you are inputting more than 1 thing from the user, say

Scanner sc = new Scanner(System.in);
int i = sc.nextInt();
double d = sc.nextDouble();
String s = sc.nextLine();

System.out.println(i);
System.out.println(d);
System.out.println(s);

So, it might look like if we run this program, it will ask for these 3 inputs and say our input values are 10, 2.5, "Welcome to java" The program should print these 3 values as it is, as we have used nextLine() so it shouldn't ignore the text after spaces that we have entered in our variable s

But, the output that you will get is -

10
2.5

And that's it, it doesn't even prompt for the String input. Now I was reading about it and to be very honest there are still some gaps in my understanding, all I could figure out was after taking the int input and then the double input when we press enter, it considers that as the prompt and ignores the nextLine().

So changing my code to something like this -

Scanner sc = new Scanner(System.in);
int i = sc.nextInt();
double d = sc.nextDouble();
sc.nextLine();
String s = sc.nextLine();

System.out.println(i);
System.out.println(d);
System.out.println(s);

does the job perfectly, so it is related to something like "\n" being stored in the keyboard buffer in the previous example which we can bypass using this.

Please if anybody knows help me with an explanation for this.

If you use Gradle - don't forget to change applicationId attribute in app/build.gradle file.

I had to do something similar for work, but in my case I had to filter all that is not a letter, number or whitespace (but you could easily modify it to your needs). The filtering is done client-side in JavaScript, but for security reasons I am also doing the filtering server-side. Since I can expect most of the strings to be clean, I would like to avoid copying the string unless I really need to. This let my to the implementation below, which should perform better for both clean and dirty strings.

public static string EnsureOnlyLetterDigitOrWhiteSpace(string input)
{
    StringBuilder cleanedInput = null;
    for (var i = 0; i < input.Length; ++i)
    {
        var currentChar = input[i];
        var charIsValid = char.IsLetterOrDigit(currentChar) || char.IsWhiteSpace(currentChar);

        if (charIsValid)
        {
            if(cleanedInput != null)
                cleanedInput.Append(currentChar);
        }
        else
        {
            if (cleanedInput != null) continue;
            cleanedInput = new StringBuilder();
            if (i > 0)
                cleanedInput.Append(input.Substring(0, i));
        }
    }

    return cleanedInput == null ? input : cleanedInput.ToString();
}

I had this issue and i have done below steps to resolve it:

1. Go to parent folder instead of child folder
2. Select SVN cleanup
3. Click on OK.

Do this step on parent folder instead of child folder!

It worked for me !

If you want to wrap your text but maintain alignment then you can wrap that cell in a minipage or varwidth environment (varwidth comes from the varwidth package). Varwidth will be "as wide as it's contents but no wider than X". You can create a custom column type which acts like "p{xx}" but shrinks to fit by using

\newcolumntype{M}[1]{>{\begin{varwidth}[t]{#1}}l<{\end{varwidth}}}

which may require the array package. Then when you use something like \begin{tabular}{llM{2in}} the first two columns we be normal left-aligned and the third column will be normal left aligned but if it gets wider than 2in then the text will be wrapped.

This one worked fine for me.

  String cc2 = "2202";
  String text2 = String.valueOf(Character.toChars(Integer.parseInt(cc2, 16)));

Now text2 will have ?.

This one is not bad too :

public static String join(String delimitor,String ... subkeys) {
    String result = null;
    if(null!=subkeys && subkeys.length>0) {
        StringBuffer joinBuffer = new StringBuffer(subkeys[0]);
        for(int idx=1;idx<subkeys.length;idx++) {
            joinBuffer.append(delimitor).append(subkeys[idx]);
        }
        result = joinBuffer.toString();
    }
    return result;
}

If only the field is required you could go with input:valid

#foo-thing:valid + .msg { visibility: visible!important; }      

 <input type="text" id="foo-thing" required="required">_x000D_
 <span class="msg" style="visibility: hidden;">Yay not empty</span>

See live on jsFiddle

OR negate using #foo-thing:invalid (credit to @SamGoody)

This worked for me and also worked with bootstrap tables

<style>
    .table td, .table th {
        font-size: 10px;
    }
</style>

A simple one liner that works can be done using:

[ "$#" -ne 1 ] && ( usage && exit 1 ) || main

This breaks down to:

1. test the bash variable for size of parameters $# not equals 1 (our number of sub commands)
2. if true then call usage() function and exit with status 1
3. else call main() function

Things to note:

• usage() can just be simple echo "$0: params"
• main can be one long script

data will return you a string representation of a list, but it is actually still a string. Just check the type of data with type(data). That means if you try using indexing on this string representation of a list as such data['fruits'][0], it will return you "[" as it is the first character of data['fruits']

You can do json.loads(data['fruits']) to convert it back to a Python list so that you can interact with regular list indexing. There are 2 other ways you can convert it back to a Python list suggested here

Java 7 support was added at build tools 19. You can now use features like the diamond operator, multi-catch, try-with-resources, strings in switches, etc. Add the following to your build.gradle.

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.0"

    defaultConfig {
        minSdkVersion 7
        targetSdkVersion 19
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
}

Gradle 1.7+, Android gradle plugin 0.6.+ are required.

Note, that only try with resources require minSdkVersion 19. Other features works on previous platforms.

lets suppose you need to place different rows of radio buttons in a form, each with separate attribute names ('option1','option2' etc) but the same class name. Perhaps you need them in multiple rows where they will each submit a value based on a scale of 1 to 5 pertaining to a question. you can write your javascript like so:

<script type="text/javascript">

    var ratings = document.getElementsByClassName('ratings'); // we access all our radio buttons elements by class name     
    var radios="";

    var i;
    for(i=0;i<ratings.length;i++){
        ratings[i].onclick=function(){
            var result = 0;
            radios = document.querySelectorAll("input[class=ratings]:checked");
            for(j=0;j<radios.length;j++){
                result =  result + + radios[j].value;
            }
            console.log(result);
            document.getElementById('overall-average-rating').innerHTML = result; // this row displays your total rating
        }
    }
</script>

I would also insert the final output into a hidden form element to be submitted together with the form.

1. Stop the docker engine and that container.
2. Go to /var/lib/docker/containers/${container_id} directory and edit hostconfig.json
3. Edit PortBindings.HostPort that you want the change.
4. Start docker engine and container.

You can try something like this:

<context:property-placeholder 
        location="${ext.properties.dir:classpath:}/servlet.properties" />

And define ext.properties.dir property in your application server / jvm, otherwise the default properties location "classpath:/" (i.e., classes dir of .jar or .war) would be used:

-Dext.properties.dir=file:/usr/local/etc/

BTW, very useful blog post.

I whipped this up and saw it might be useful for some. (Yes, CoffeeScript. Sue me.)

Directive

app.directive 'times', ->
  link: (scope, element, attrs) ->
    repeater = element.html()
    scope.$watch attrs.times, (value) ->
      element.html ''
      return unless value?
      element.html Array(value + 1).join(repeater)

To use:

HTML

<div times="customer.conversations_count">
  <i class="icon-picture></i>
</div>

Can this get any simpler?

I'm wary about filters because Angular likes to re-evaluate them for no good reason all the time, and it's a huge bottleneck if you have thousands of them like I do.

This directive will even watch for changes in your model, and update the element accordingly.

There are two ways to validate user input: annotations and by inheriting Spring's Validator class. For simple cases, the annotations are nice. If you need complex validations (like cross-field validation, eg. "verify email address" field), or if your model is validated in multiple places in your application with different rules, or if you don't have the ability to modify your model object by placing annotations on it, Spring's inheritance-based Validator is the way to go. I'll show examples of both.

The actual validation part is the same regardless of which type of validation you're using:

RequestMapping(value="fooPage", method = RequestMethod.POST)
public String processSubmit(@Valid @ModelAttribute("foo") Foo foo, BindingResult result, ModelMap m) {
    if(result.hasErrors()) {
        return "fooPage";
    }
    ...
    return "successPage";
}

If you are using annotations, your Foo class might look like:

public class Foo {

    @NotNull
    @Size(min = 1, max = 20)
    private String name;

    @NotNull
    @Min(1)
    @Max(110)
    private Integer age;

    // getters, setters
}

Annotations above are javax.validation.constraints annotations. You can also use Hibernate's org.hibernate.validator.constraints, but it doesn't look like you are using Hibernate.

Alternatively, if you implement Spring's Validator, you would create a class as follows:

public class FooValidator implements Validator {

    @Override
    public boolean supports(Class<?> clazz) {
        return Foo.class.equals(clazz);
    }

    @Override
    public void validate(Object target, Errors errors) {

        Foo foo = (Foo) target;

        if(foo.getName() == null) {
            errors.rejectValue("name", "name[emptyMessage]");
        }
        else if(foo.getName().length() < 1 || foo.getName().length() > 20){
            errors.rejectValue("name", "name[invalidLength]");
        }

        if(foo.getAge() == null) {
            errors.rejectValue("age", "age[emptyMessage]");
        }
        else if(foo.getAge() < 1 || foo.getAge() > 110){
            errors.rejectValue("age", "age[invalidAge]");
        }
    }
}

If using the above validator, you also have to bind the validator to the Spring controller (not necessary if using annotations):

@InitBinder("foo")
protected void initBinder(WebDataBinder binder) {
    binder.setValidator(new FooValidator());
}

Also see Spring docs.

Hope that helps.

Well any Javascript object functions sort-of like a "map"

randomObject['hello'] = 'world';

Typically people build simple objects for the purpose:

var myMap = {};

// ...

myMap[newKey] = newValue;

edit — well the problem with having an explicit "put" function is that you'd then have to go to pains to avoid having the function itself look like part of the map. It's not really a Javascripty thing to do.

13 Feb 2014 — modern JavaScript has facilities for creating object properties that aren't enumerable, and it's pretty easy to do. However, it's still the case that a "put" property, enumerable or not, would claim the property name "put" and make it unavailable. That is, there's still only one namespace per object.

Sure you know, but if its a constant then const MyVariable as Integer = 123 otherwise your out of luck; the variable must be assigned an initial value elsewhere.

You could:

public property get myIntegerThing() as integer
    myIntegerThing= 123
end property

In a Class module then globally create it;

public cMyStuff as new MyStuffClass

So cMyStuff.myIntegerThing is available immediately.

The different methods are indications of priority. As you've listed them, they're going from least to most important. I think how you specifically map them to debug logs in your code depends on the component or app you're working on, as well as how Android treats them on different build flavors (eng, userdebug, and user). I have done a fair amount of work in the native daemons in Android, and this is how I do it. It may not apply directly to your app, but there may be some common ground. If my explanation sounds vague, it's because some of this is more of an art than a science. My basic rule is to be as efficient as possible, ensure you can reasonably debug your component without killing the performance of the system, and always check for errors and log them.

V - Printouts of state at different intervals, or upon any events occurring which my component processes. Also possibly very detailed printouts of the payloads of messages/events that my component receives or sends.

D - Details of minor events that occur within my component, as well as payloads of messages/events that my component receives or sends.

I - The header of any messages/events that my component receives or sends, as well as any important pieces of the payload which are critical to my component's operation.

W - Anything that happens that is unusual or suspicious, but not necessarily an error.

E - Errors, meaning things that aren't supposed to happen when things are working as they should.

The biggest mistake I see people make is that they overuse things like V, D, and I, but never use W or E. If an error is, by definition, not supposed to happen, or should only happen very rarely, then it's extremely cheap for you to log a message when it occurs. On the other hand, if every time somebody presses a key you do a Log.i(), you're abusing the shared logging resource. Of course, use common sense and be careful with error logs for things outside of your control (like network errors), or those contained in tight loops.

Maybe Bad

Log.i("I am here");

Good

Log.e("I shouldn't be here");

With all this in mind, the closer your code gets to "production ready", the more you can restrict the base logging level for your code (you need V in alpha, D in beta, I in production, or possibly even W in production). You should run through some simple use cases and view the logs to ensure that you can still mostly understand what's happening as you apply more restrictive filtering. If you run with the filter below, you should still be able to tell what your app is doing, but maybe not get all the details.

logcat -v threadtime MyApp:I *:S

From the man page:

Sending mail

To send a message to one or more people, mailx can be invoked with arguments which are the names of people to whom the mail will be sent. The user is then expected to type in his message, followed by an ‘control-D’ at the beginning of a line.

In other words, mailx reads the content to send from standard input and can be redirected to like normal. E.g.:

ls -l $HOME | mailx -s "The content of my home directory" [email protected]

You don't use the : syntax - pull always modifies the currently checked-out branch. Thus:

git pull origin my_remote_branch

while you have my_local_branch checked out will do what you want.

Since you already have the tracking branch set, you don't even need to specify - you could just do...

git pull

while you have my_local_branch checked out, and it will update from the tracked branch.

You can use method shown here and replace isNull with isnan:

from pyspark.sql.functions import isnan, when, count, col

df.select([count(when(isnan(c), c)).alias(c) for c in df.columns]).show()
+-------+----------+---+
|session|timestamp1|id2|
+-------+----------+---+
|      0|         0|  3|
+-------+----------+---+

or

df.select([count(when(isnan(c) | col(c).isNull(), c)).alias(c) for c in df.columns]).show()
+-------+----------+---+
|session|timestamp1|id2|
+-------+----------+---+
|      0|         0|  5|
+-------+----------+---+

How I would write it:

var left: Node? = null

fun show() {
     val left = left ?: return
     queue.add(left) // no error because we return if it is null
}
