Just to kick a long-dead horse, because I've had to implement an optional argument in the middle of two or more required arguments. Use the arguments array and use the last one as the required non-optional argument.

my_function() {
  var options = arguments[argument.length - 1];
  var content = arguments.length > 1 ? arguments[0] : null;
}

set ORACLE_SID=<YOUR_SID>
sqlplus "/as sysdba"
alter system disable restricted session;

or maybe

shutdown abort;

or maybe

lsnrctl stop

lsnrctl start

You may want to use:

SELECT Name, 'Unpaid' AS Status FROM table;

The SELECT clause syntax, as defined in MSDN: SELECT Clause (Transact-SQL), is as follows:

SELECT [ ALL | DISTINCT ]
[ TOP ( expression ) [ PERCENT ] [ WITH TIES ] ] 
<select_list> 

Where the expression can be a constant, function, any combination of column names, constants, and functions connected by an operator or operators, or a subquery.

UPDATE table SET column=0 WHERE column IS NULL

May be i am too late to the party but this will parse/escape single quote (don't want to get into a battle on parse vs escape)..

JSON.parse("\"'\"")

You'll have to use an HttpServletRequestWrapper:

public void doFilter(final ServletRequest request, final ServletResponse response, final FilterChain chain) throws IOException, ServletException {
    final HttpServletRequest httpRequest = (HttpServletRequest) request;
    HttpServletRequestWrapper wrapper = new HttpServletRequestWrapper(httpRequest) {
        @Override
        public String getHeader(String name) {
            final String value = request.getParameter(name);
            if (value != null) {
                return value;
            }
            return super.getHeader(name);
        }
    };
    chain.doFilter(wrapper, response);
}

Depending on what you want to do you may need to implement other methods of the wrapper like getHeaderNames for instance. Just be aware that this is trusting the client and allowing them to manipulate any HTTP header. You may want to sandbox it and only allow certain header values to be modified this way.

Version that works in all browsers

This function does what you want, and performs a lot faster than the option suggested in the accepted answer :

var repeat = function(str, count) {
    var array = [];
    for(var i = 0; i <= count;)
        array[i++] = str;
    return array.join('');
}

You use it like this :

var repeatedCharacter = repeat("a", 10);

To compare the performance of this function with that of the option proposed in the accepted answer, see this Fiddle and this Fiddle for benchmarks.

Version for moderns browsers only

In modern browsers, you can now also do this :

var repeatedCharacter = "a".repeat(10) };

This option is even faster. However, unfortunately it doesn't work in any version of Internet explorer.

The numbers in the table specify the first browser version that fully supports the method :

They are pretty much the same thing. Thanks to the magic of C++, a struct can hold functions, use inheritance, created using "new" and so on just like a class

The only functional difference is that a class begins with private access rights, while a struct begins with public. This is the maintain backwards compatibility with C.

In practice, I've always used structs as data holders and classes as objects.

Yeah, when ASP.NET web.config gets updated, the whole application gets restarted which means the web.config gets reloaded.

Escape single quote with an additional single as Kirtan pointed out
And if you are trying to execute a dynamic sql (which is not a good idea in the first place) via sp_executesql then the below code would work for you

sp_executesql N'INSERT INTO SomeTable (SomeColumn) VALUES (''John''''s'')'

A solution that works with all possible line endings including mixed ones and keeping empty lines as well can be achieved using two replaces and one split as follows

text.replace(/\r\n/g, "\r").replace(/\n/g, "\r").split(/\r/);

some code to test it

  var CR = "\x0D";  //   \r
  var LF = "\x0A";  //   \n

  var mixedfile = "00" + CR + LF +            // 1 x win
                  "01" + LF +                 // 1 x linux
                  "02" + CR +                 // 1 x old mac
                  "03" + CR + CR +            // 2 x old mac
                  "05" + LF + LF +            // 2 x linux
                  "07" + CR + LF + CR + LF +  // 2 x win
                  "09";

  function showarr (desc, arr)
  {
     console.log ("// ----- " + desc);
     for (var ii in arr)
        console.log (ii + ") [" + arr[ii] +  "] (len = " + arr[ii].length + ")");
  }

  showarr ("using 2 replace + 1 split", 
           mixedfile.replace(/\r\n/g, "\r").replace(/\n/g, "\r").split(/\r/));

and the output

  // ----- using 2 replace + 1 split
  0) [00] (len = 2)
  1) [01] (len = 2)
  2) [02] (len = 2)
  3) [03] (len = 2)
  4) [] (len = 0)
  5) [05] (len = 2)
  6) [] (len = 0)
  7) [07] (len = 2)
  8) [] (len = 0)
  9) [09] (len = 2)

I like the answer but I think it would be better that you create a global scope function that will allow you to set the scope variable needed.

So in the globalController create

$scope.setScopeVariable = function(variable, value){
    $scope[variable] = value;
}

and then in your html file call it

{{setScopeVariable('myVar', 'whatever')}}

This will then allow you to use $scope.myVar in your respective controller

In you app config file change the url to localhost/example/public

Then when you want to link to something

<a href="{{ url('page') }}">Some Text</a>

without blade

<a href="<?php echo url('page') ?>">Some Text</a>

Issue

Since you are using WebSocket, spender is correct. After recieving the initial data from the WebSocket, you need to send the handshake message from the C# server before any further information can flow.

HTTP/1.1 101 Web Socket Protocol Handshake
Upgrade: websocket
Connection: Upgrade
WebSocket-Origin: example
WebSocket-Location: something.here
WebSocket-Protocol: 13

Something along those lines.

You can do some more research into how WebSocket works on w3 or google.

This exception will come in case your server is based on JDK 7 and your client is on JDK 6 and using SSL certificates. In JDK 7 sslv2hello message handshaking is disabled by default while in JDK 6 sslv2hello message handshaking is enabled. For this reason when your client trying to connect server then a sslv2hello message will be sent towards server and due to sslv2hello message disable you will get this exception. To solve this either you have to move your client to JDK 7 or you have to use 6u91 version of JDK. But to get this version of JDK you have to get the MOS (My Oracle Support) Enterprise support. This patch is not public.

I've developed jmxfuse which exposes JMX Mbeans as a Linux FUSE filesystem with similar functionality as the /proc fs. It relies on Jolokia as the bridge to JMX. Attributes and operations are exposed for reading and writing.

http://code.google.com/p/jmxfuse/

For example, to read an attribute:

me@oddjob:jmx$ cd log4j/root/attributes
me@oddjob:jmx$ cat priority

to write an attribute:

me@oddjob:jmx$ echo "WARN" > priority

to invoke an operation:

me@oddjob:jmx$ cd Catalina/none/none/WebModule/localhost/helloworld/operations/addParameter
me@oddjob:jmx$ echo "myParam myValue" > invoke

In case someone doesn't realize it, one way to do this would be to combine Christophe and RSabet's answers:

from datetime import datetime
import time

fmt = '%Y-%m-%d %H:%M:%S'
d1 = datetime.strptime('2010-01-01 17:31:22', fmt)
d2 = datetime.strptime('2010-01-03 20:15:14', fmt)

diff = d2 -d1
diff_minutes = (diff.days * 24 * 60) + (diff.seconds/60)

print(diff_minutes)
> 3043

Here is your exact answer...

const char LineFeed = '\n'; // #10
string temp = new System.Text.RegularExpressions.Regex(
                  LineFeed
              ).Replace(mystring, string.Empty);

But this one is much better... Specially if you are trying to split the lines (you may also use it with Split)

const char CarriageReturn = '\r'; // #13
const char LineFeed = '\n'; // #10
string temp = new System.Text.RegularExpressions.Regex(
                  string.Format("{0}?{1}", CarriageReturn, LineFeed)
              ).Replace(mystring, string.Empty);

    s0 = "hello";

    // Method #1: Just use "c_str()" method to obtain a pointer to a

If you are using the grid or alike component: In XAML, make sure that the elements in the grid have Grid.Row and Grid.Column defined, and ensure tha they don't have margins. If you used designer mode, or Expression Blend, it could have assigned margins relative to the whole grid instead of to particular cells. As for cell sizing, I add an extra cell that fills up the rest of the space:

    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
        <RowDefinition Height="*"/>
    </Grid.RowDefinitions>

From Python 2.5 onwards you can do:

value = b if a > 10 else c

Previously you would have to do something like the following, although the semantics isn't identical as the short circuiting effect is lost:

value = [c, b][a > 10]

There's also another hack using 'and ... or' but it's best to not use it as it has an undesirable behaviour in some situations that can lead to a hard to find bug. I won't even write the hack here as I think it's best not to use it, but you can read about it on Wikipedia if you want.

Well, this seemed to work on my Razor Page and never even did a round trip to the .cs file. This is old html way. It might be useful.

<input type="reset" value="Reset">

Another way of achieving it would be to temporary edit the gitignore file, add the file and then revert back the gitignore. A bit hacky i feel

1. Use Update.

Drawing from Van Nguyen's answer above, use update instead of save. This gives you access to the upsert option.

NOTE: This method overrides the entire document when found (From the docs)

var conditions = { name: 'borne' }   , update = { $inc: { visits: 1 }} , options = { multi: true };

Model.update(conditions, update, options, callback);

function callback (err, numAffected) {   // numAffected is the number of updated documents })

1.a. Use $set

If you want to update a selection of the document, but not the whole thing, you can use the $set method with update. (again, From the docs)... So, if you want to set...

var query = { name: 'borne' };  Model.update(query, ***{ name: 'jason borne' }***, options, callback)

Send it as...

Model.update(query, ***{ $set: { name: 'jason borne' }}***, options, callback)

This helps prevent accidentally overwriting all of your document(s) with { name: 'jason borne' }.

What you are talking about is the preview image and text that Facebook extracts when you share a link. Facebook uses the Open Graph Protocol to get this data.

Essentially, all you'll have to do is place these og:meta tags on the URL that you want to share -

<meta property="og:title" content="The Rock"/>
<meta property="og:type" content="movie"/>
<meta property="og:url" content="http://www.imdb.com/title/tt0117500/"/>
<meta property="og:image" content="http://ia.media-imdb.com/rock.jpg"/>
<meta property="og:site_name" content="IMDb"/>
<meta property="fb:admins" content="USER_ID"/>
<meta property="og:description"
      content="A group of U.S. Marines, under command of
               a renegade general, take over Alcatraz and
               threaten San Francisco Bay with biological
               weapons."/>

As you can see there are both an image property and a description. When you make changes to your pages og:meta tags, you can test these changes using the Facebook Debugger. It will tell you if you have made any mistakes (and how to fix them!)

String sql = "select count(*) from message";
ps =  cn.prepareStatement(sql);

rs = ps.executeQuery();
int rowCount = 0;
while(rs.next()) {
    rowCount = Integer.parseInt(rs.getString("count(*)"));
    System.out.println(Integer.parseInt(rs.getString("count(*)")));
}
System.out.println("Count : " + rowCount);

There are three "default" encodings:

• file.encoding:
  System.getProperty("file.encoding")

• java.nio.Charset:
  Charset.defaultCharset()

• And the encoding of the InputStreamReader:
  InputStreamReader.getEncoding()

You can read more about it on this page.

You can't do replacing, you have to replace SOMETHING with SOMETHING, and you neither have both.

I find that the best way is to use this...

It's probably because launchctl is managing your mongod instance. If you want to start and shutdown mongod instance, unload that first:

launchctl unload -w ~/Library/LaunchAgents/org.mongodb.mongod.plist

Then start mongod manually:

mongod -f path/to/mongod.conf --fork

You can find your mongod.conf location from ~/Library/LaunchAgents/org.mongodb.mongod.plist.

After that, db.shutdownServer() would work just fine.

Added Feb 22 2014:

If you have mongodb installed via homebrew, homebrew actually has a handy brew services command. To show current running services:

brew services list

To start mongodb:

brew services start mongodb-community

To stop mongodb if it's already running:

brew services stop mongodb-community

Update*

As edufinn pointed out in the comment, brew services is now available as user-defined command and can be installed with following command: brew tap gapple/services.

Thread th = new Thread(function1);

For Swift 3 and XCode 8, this worked. Follow below steps to achieve this:-

viewDidLoad()
    {
        let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout()
        var width = UIScreen.main.bounds.width
        layout.sectionInset = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
    width = width - 10
    layout.itemSize = CGSize(width: width / 2, height: width / 2)
        layout.minimumInteritemSpacing = 0
        layout.minimumLineSpacing = 0
        collectionView!.collectionViewLayout = layout
    }

When putting resource files in another location is not the best solution you can use:

<build>
  <resources>
    <resource>
      <directory>src/main/java</directory>
      <excludes>
        <exclude>**/*.java</exclude>
      </excludes>
    </resource>
  </resources>
<build>

For example when resources files (e.g. jaxb.properties) goes deep inside packages along with Java classes.

I Hope that this helps you out... Because I tried all the answers but nothing worked perfectly. So, I had to come up with a solution on my own.

#horizontal-style {
  padding-inline-start: 0 !important; // Just in case if you find that there is an extra padding at the start of the line 
  justify-content: space-around;
  display: flex;
}

#horizontal-style a {
    text-align: center;
    color: white;
    text-decoration: none;
}

for me, the problem was from require('jquery-validation') i added in the begging of that js file which Validate method used which is necessary as an npm module

unfortunately, when web pack compiles the js files, they aren't in order, so that the validate method is before defining it! and the error comes

so better to use another js file for compiling this library or use local validate method file or even using CDN but in all cases make sure you attached jquery before

This may be what your after:

SELECT Count(Owner_ID), Name
FROM (
    SELECT M.Owner_ID, O.Name, T.Type
    FROM Transport As T, Owner As O, Motorbike As M
    WHERE T.Type = 'Motorbike'
    AND O.Owner_ID = M.Owner_ID
    AND T.Type_ID = M.Motorbike_ID

    UNION ALL

    SELECT C.Owner_ID, O.Name, T.Type
    FROM Transport As T, Owner As O, Car As C
    WHERE T.Type = 'Car'
    AND O.Owner_ID = C.Owner_ID
    AND T.Type_ID = C.Car_ID
)
GROUP BY Owner_ID

Try using WSDL.exe and then including the generated file (.cs) into your project.

Fire up the Visual Studio Command prompt (under visual studio/tools in the start menu) then type

>wsdl.exe [path To Your WSDL File]

That'll spit out a file, which you copy/move and include in your project. That file contains a class which is a proxy to your sevice, Fire up an instance of that class, and it'll have a URL property you can set on the fly, and a bunch of methods that you can call. It'll also generate classes for all/any complex objects passed across the service interface.

Horizontal scrollbars in a HTML Select are not natively supported. However, here's a way to create the appearance of a horizontal scrollbar:

1. First create a css class

<style type="text/css">
 .scrollable{
   overflow: auto;
   width: 70px; /* adjust this width depending to amount of text to display */
   height: 80px; /* adjust height depending on number of options to display */
   border: 1px silver solid;
 }
 .scrollable select{
   border: none;
 }
</style>

2. Wrap the SELECT inside a DIV - also, explicitly set the size to the number of options.

<div class="scrollable">
<select size="6" multiple="multiple">
    <option value="1" selected>option 1 The Long Option</option>
    <option value="2">option 2</option>
    <option value="3">option 3</option>
    <option value="4">option 4</option>
    <option value="5">option 5 Another Longer than the Long Option ;)</option>
    <option value="6">option 6</option>
</select>
</div>

The move instruction copies a value from one register to another. The li instruction loads a specific numeric value into that register.

For the specific case of zero, you can use either the constant zero or the zero register to get that:

move $s0, $zero
li   $s0, 0

There's no register that generates a value other than zero, though, so you'd have to use li if you wanted some other number, like:

li $s0, 12345678

Here's my theory why most people (including me) prefer while(){} loops to do{}while(): A while(){} loop can easily be adapted to perform like a do..while() loop while the opposite is not true. A while loop is in a certain way "more general". Also programmers like easy to grasp patterns. A while loop says right at start what its invariant is and this is a nice thing.

Here's what I mean about the "more general" thing. Take this do..while loop:

do {
 A;
 if (condition) INV=false; 
 B;
} while(INV);

Transforming this in to a while loop is straightforward:

INV=true;
while(INV) {
 A;
 if (condition) INV=false; 
 B;
}

Now, we take a model while loop:

while(INV) {
     A;
     if (condition) INV=false; 
     B;
}

And transform this into a do..while loop, yields this monstrosity:

if (INV) {
 do
 {
         A;
         if (condition) INV=false; 
         B;

 } while(INV)
}

Now we have two checks on opposite ends and if the invariant changes you have to update it on two places. In a certain way do..while is like the specialized screwdrivers in the tool box which you never use, because the standard screwdriver does everything you need.

When you call a Linq statement like this:

// x = new List<string>();
var count = x.Count(s => s.StartsWith("x"));

You are actually using an extension method in the System.Linq namespace, so what the compiler translates this into is:

var count = Enumerable.Count(x, s => s.StartsWith("x"));

So the error you are getting above is because the first parameter, source (which would be x in the sample above) is null.

All these patterns, MVC, MVVM, MVP, and Presentation Model, can be applied to Android apps, but without a third-party framework, it is not easy to get well-organized structure and clean code.

MVVM is originated from PresentationModel. When we apply MVC, MVVM, and Presentation Model to an Android app, what we really want is to have a clear structured project and more importantly easier for unit tests.

At the moment, without an third-party framework, you usually have lots of code (like addXXListener(), findViewById(), etc.), which does not add any business value. What's more, you have to run Android unit tests instead of normal JUnit tests, which take ages to run and make unit tests somewhat impractical.

For these reasons, some years ago we started an open source project, RoboBinding - A data-binding Presentation Model framework for the Android platform. RoboBinding helps you write UI code that is easier to read, test, and maintain. RoboBinding removes the need of unnecessary code like addXXListener or so, and shifts UI logic to the Presentation Model, which is a POJO and can be tested via normal JUnit tests. RoboBinding itself comes with more than 300 JUnit tests to ensure its quality.

You can make them appear more "clearly" with a command:

gcc -### -E - -march=native 2>&1 | sed -r '/cc1/!d;s/(")|(^.* - )//g'

and you can get rid of flags with -mno-* with:

gcc -### -E - -march=native 2>&1 | sed -r '/cc1/!d;s/(")|(^.* - )|( -mno-[^\ ]+)//g'

Start by turning the text into a list of lists. That will take care of the parsing part:

lol = list(csv.reader(open('text.txt', 'rb'), delimiter='\t'))

The rest can be done with indexed lookups:

d = dict()
key = lol[6][0]      # cell A7
value = lol[6][3]    # cell D7
d[key] = value       # add the entry to the dictionary
 ...

Interfaces are concerned with polymorphism which is inherently tied to object instances, not classes. Therefore static doesn't make sense in the context of an interface.

2's complement is essentially a way of coming up with the additive inverse of a binary number. Ask yourself this: Given a number in binary form (present at a fixed length memory location), what bit pattern, when added to the original number (at the fixed length memory location), would make the result all zeros ? (at the same fixed length memory location). If we could come up with this bit pattern then that bit pattern would be the -ve representation (additive inverse) of the original number; as by definition adding a number to its additive inverse always results in zero. Example: take 5 which is 101 present inside a single 8 bit byte. Now the task is to come up with a bit pattern which when added to the given bit pattern (00000101) would result in all zeros at the memory location which is used to hold this 5 i.e. all 8 bits of the byte should be zero. To do that, start from the right most bit of 101 and for each individual bit, again ask the same question: What bit should I add to the current bit to make the result zero ? continue doing that taking in account the usual carry over. After we are done with the 3 right most places (the digits that define the original number without regard to the leading zeros) the last carry goes in the bit pattern of the additive inverse. Furthermore, since we are holding in the original number in a single 8 bit byte, all other leading bits in the additive inverse should also be 1's so that (and this is important) when the computer adds "the number" (represented using the 8 bit pattern) and its additive inverse using "that" storage type (a byte) the result in that byte would be all zeros.

 1 1 1

   1 0 1

If you want to calculate it yourself, then you can use the Haversine formula:

var rad = function(x) {
  return x * Math.PI / 180;
};

var getDistance = function(p1, p2) {
  var R = 6378137; // Earth’s mean radius in meter
  var dLat = rad(p2.lat() - p1.lat());
  var dLong = rad(p2.lng() - p1.lng());
  var a = Math.sin(dLat / 2) * Math.sin(dLat / 2) +
    Math.cos(rad(p1.lat())) * Math.cos(rad(p2.lat())) *
    Math.sin(dLong / 2) * Math.sin(dLong / 2);
  var c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));
  var d = R * c;
  return d; // returns the distance in meter
};

If you want the String composed of the last three characters, you can use substring(int):

String new_word = word.substring(word.length() - 3);

If you actually want them as a character array, you should write

char[] buffer = new char[3];
int length = word.length();
word.getChars(length - 3, length, buffer, 0);

The first two arguments to getChars denote the portion of the string you want to extract. The third argument is the array into which that portion will be put. And the last argument gives the position in the buffer where the operation starts.

If the string has less than three characters, you'll get an exception in either of the above cases, so you might want to check for that.

Hi try the following code it will be useful to you,

((ImageView)findViewById(R.id.ImageViewButton)).setOnTouchListener(new View.OnTouchListener() {
    public boolean onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_DOWN)
            ((ImageView) v.findViewById(R.id.ImageViewButton)).setImageResource(R.drawable.image_over);

        if(event.getAction() == MotionEvent.ACTION_UP)
            ((ImageView) v.findViewById(R.id.ImageViewButton)).setImageResource(R.drawable.image_normal);

        return false;
    }
});

Decision tree between ES5, ES6 and TypeScript

Do you mind having a build step?

• Yes - Use ES5
• No - keep going

Do you want to use types?

• Yes - Use TypeScript
• No - Use ES6

More Details

ES5 is the JavaScript you know and use in the browser today it is what it is and does not require a build step to transform it into something that will run in today's browsers

ES6 (also called ES2015) is the next iteration of JavaScript, but it does not run in today's browsers. There are quite a few transpilers that will export ES5 for running in browsers. It is still a dynamic (read: untyped) language.

TypeScript provides an optional typing system while pulling in features from future versions of JavaScript (ES6 and ES7).

Note: a lot of the transpilers out there (i.e. babel, TypeScript) will allow you to use features from future versions of JavaScript today and exporting code that will still run in today's browsers.

Throwing my hat in the ring:

1) First we execute the NOT function on a set of integers, evaluating non-zeros to 0 and zeros to 1

2) Then we search for the MAX in our original set of integers

3) Then we multiply each number in the set generated in step 1 by the MAX found in step 2, setting ones as 0 and zeros as MAX

4) Then we add the set generated in step 3 to our original set

5) Lastly we look for the MIN in the set generated in step 4

{=MIN((NOT(A1:A5000)* MAX(A1:A5000))+ A1:A5000)}

If you know the rough range of numbers, you can replace the MAX(RANGE) with a constant. This speeds things up slightly, still not enough to compete with the faster functions.

Also did a quick test run on data set of 5000 integers with formula being executed 5000 times.

{=SMALL(A1:A5000,COUNTIF(A1:A5000,0)+1)}

This is a bug in the Google Play services library, and it is filed here under issue 755.

Unfortunately, there isn't any solution yet.

In my experience, regex solutions have too many false positives and filter_var() solutions have false negatives (especially with all of the newer TLDs).

Instead, it's better to make sure the address has all of the required parts of an email address (user, "@" symbol, and domain), then verify that the domain itself exists.

There is no way to determine (server side) if an email user exists for an external domain.

This is a method I created in a Utility class:

public static function validateEmail($email)
{
    // SET INITIAL RETURN VARIABLES

        $emailIsValid = FALSE;

    // MAKE SURE AN EMPTY STRING WASN'T PASSED

        if (!empty($email))
        {
            // GET EMAIL PARTS

                $domain = ltrim(stristr($email, '@'), '@') . '.';
                $user   = stristr($email, '@', TRUE);

            // VALIDATE EMAIL ADDRESS

                if
                (
                    !empty($user) &&
                    !empty($domain) &&
                    checkdnsrr($domain)
                )
                {$emailIsValid = TRUE;}
        }

    // RETURN RESULT

        return $emailIsValid;
}

mv -f source target

From the man page:

-f, --force
          do not prompt before overwriting

Starting from tslint v5.8.0 you can set an exclude property under your linterOptions key in your tslint.json file:

{
  "extends": "tslint:latest",
  "linterOptions": {
      "exclude": [
          "bin",
          "**/__test__",
          "lib/*generated.js"
      ]
  }
}

More information on this here.

To see the keys:

for key in d.keys():
    print(key)

To get the values that each key is referencing:

for key in d.keys():
    print(d[key])

Add to a list:

for key in d.keys():
    mylist.append(d[key])

This is the answer, hope it helps someone :)

As "@sarnold", aptly pointed out, any process can send signal to any other process, hence, one process can send SIGABORT to other process & in that case the receiving process is unable to distinguish whether its coming because of its own tweaking of memory etc, or someone else has "unicastly", send to it.

In one of the systems I worked there is one deadlock detector which actually detects if process is coming out of some task by giving heart beat or not. If not, then it declares the process is in deadlock state and sends SIGABORT to it.

I just wanted to share this prospective with reference to question asked.

This should solve your problem:

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

Give a look also as this SQL Fiddle for test.

Or a 1-liner:

perl -p -i -e 's/\r\n$/\n/g' file1.txt file2.txt ... filen.txt

You definitely should not need the debug version of the CRT if you're compiling in "release" mode. You can tell they're the debug versions of the DLLs because they end with a d.

More to the point, the debug version is not redistributable, so it's not as simple as "packaging" it with your executable, or zipping up those DLLs.

Check to be sure that you're compiling all components of your application in "release" mode, and that you're linking the correct version of the CRT and any other libraries you use (e.g., MFC, ATL, etc.).

You will, of course, require msvcr100.dll (note the absence of the d suffix) and some others if they are not already installed. Direct your friends to download the Visual C++ 2010 Redistributable (or x64), or include this with your application automatically by building an installer.

date -j -f "%Y-%m-%d %H:%M:%S" "2020-04-07 00:00:00" "+%s"

It will print the dynamic seconds when without %H:%M:%S and 00:00:00.

The self name is used as the instance reference in class instances. It is only used in class method definitions. Don't use it in functions.

You also cannot reference local variables from other functions or methods with it. You can only reference instance or class attributes using it.

It sets how the database server sorts (compares pieces of text). in this case:

SQL_Latin1_General_CP1_CI_AS

breaks up into interesting parts:

1. latin1 makes the server treat strings using charset latin 1, basically ascii
2. CP1 stands for Code Page 1252
3. CI case insensitive comparisons so 'ABC' would equal 'abc'
4. AS accent sensitive, so 'ü' does not equal 'u'

P.S. For more detailed information be sure to read @solomon-rutzky's answer.

At its core, Git is a set of command line utility programs that are designed to execute on a Unix style command-line environment. Modern operating systems like Linux and macOS both include built-in Unix command line terminals. This makes Linux and macOS complementary operating systems when working with Git. Microsoft Windows instead uses Windows command prompt, a non-Unix terminal environment.

What is Git Bash?

Git Bash is an application for Microsoft Windows environments which provides an emulation layer for a Git command line experience. Bash is an acronym for Bourne Again Shell. A shell is a terminal application used to interface with an operating system through written commands. Bash is a popular default shell on Linux and macOS. Git Bash is a package that installs Bash, some common bash utilities, and Git on a Windows operating system.

There's now a UITextField delegate method available on iOS13+

The power in dBm is the 10 times the logarithm of the ratio of actual Power/1 milliWatt.

dBm stands for "decibel milliwatts". It is a convenient way to measure power. The exact formula is

P(dBm) = 10 · log10( P(W) / 1mW ) 

where

P(dBm) = Power expressed in dBm   
P(W) = the absolute power measured in Watts   
mW = milliWatts   
log10 = log to base 10

From this formula, the power in dBm of 1 Watt is 30 dBm. Because the calculation is logarithmic, every increase of 3dBm is approximately equivalent to doubling the actual power of a signal.

There is a conversion calculator and a comparison table here. There is also a comparison table on the Wikipedia english page, but the value it gives for mobile networks is a bit off.

Your actual question was "does the - sign count?"

The answer is yes, it does.

-85 dBm is less powerful (smaller) than -60 dBm. To understand this, you need to look at negative numbers. Alternatively, think about your bank account. If you owe the bank 85 dollars/rands/euros/rupees (-85), you're poorer than if you only owe them 65 (-65), i.e. -85 is smaller than -65. Also, in temperature measurements, -85 is colder than -65 degrees.

Signal strengths for mobile networks are always negative dBm values, because the transmitted network is not strong enough to give positive dBm values.

How will this affect your location finding? I have no idea, because I don't know what technology you are using to estimate the location. The values you quoted correspond roughly to a 5 bar network in GSM, UMTS or LTE, so you shouldn't have be having any problems due to network strength.

As of Rails 6, you can simply call redirect_to followed by the path you wish to redirect to such as home_path, and then pass is a hash of key-value pairs.

example:

redirect_to home_path(name: 'Jason', needs: 'help with rails', help: true)

After this, you will be able to retrieve these values from the params hash.

ex

params[:name]

to retrieve the string 'Jason'

Use split on string:

var array = coolVar.split(/-/);

MAMP USERS editing php.ini solves this - there is a line:

A binary search works by dividing the problem in half repeatedly, something like this (details omitted):

Example looking for 3 in [4,1,3,8,5]

1. Order your list of items [1,3,4,5,8]
2. Look at the middle item (4),
   • If it is what you are looking for, stop
   • If it is greater, look at the first half
   • If it is less, look at the second half
3. Repeat step 2 with the new list [1, 3], find 3 and stop

It is a bi-nary search when you divide the problem in 2.

The search only requires log2(n) steps to find the correct value.

Cancelation of requests issued with $http is not supported with the current version of AngularJS. There is a pull request opened to add this capability but this PR wasn't reviewed yet so it is not clear if its going to make it into AngularJS core.

It appears that the up-to-date answer to this is to not use filter-branch directly (at least git itself does not recommend it anymore), and defer that work to an external tool. In particular, git-filter-repo is currently recommended. The author of that tool provides arguments on why using filter-branch directly can lead to issues.

Most of the multi-line scripts above to remove dir from the history could be re-written as:

git filter-repo --path dir --invert-paths

The tool is more powerful than just that, apparently. You can apply filters by author, email, refname and more (full manpage here). Furthermore, it is fast. Installation is easy - it is distributed in a variety of formats.

I had the same issue. Ran 5 or 6 hours of researches. A simple solution seems to be working. I just had to convert my folder to application from iis. It worked fine. (this was a scenario where I had done a migration from server 2003 to server 2008 R2)

(1) Open IIS and select the website and the appropriate folder that needs to be converted. Right-click and select Convert to Application.

Well, after searching around and cobbling together various points from around StackOverflow (gee, I love this place already), most of the problems were already past this stage. I did manage to work out an answer to my problem though.

How to create a resource:

In my case, I want to create an icon. It's a similar process, no matter what type of data you want to add as a resource though.

• Right click the project you want to add a resource to. Do this in the Solution Explorer. Select the "Properties" option from the list.
• Click the "Resources" tab.
• The first button along the top of the bar will let you select the type of resource you want to add. It should start on string. We want to add an icon, so click on it and select "Icons" from the list of options.
• Next, move to the second button, "Add Resource". You can either add a new resource, or if you already have an icon already made, you can add that too. Follow the prompts for whichever option you choose.
• At this point, you can double click the newly added resource to edit it. Note, resources also show up in the Solution Explorer, and double clicking there is just as effective.

How to use a resource:

Great, so we have our new resource and we're itching to have those lovely changing icons... How do we do that? Well, lucky us, C# makes this exceedingly easy.

There is a static class called Properties.Resources that gives you access to all your resources, so my code ended up being as simple as:

paused = !paused;
if (paused)
    notifyIcon.Icon = Properties.Resources.RedIcon;
else
    notifyIcon.Icon = Properties.Resources.GreenIcon;

Done! Finished! Everything is simple when you know how, isn't it?

A comment about Will's answer, you might want to replace HttpContext.Current.Response.End(); with HttpContext.Current.ApplicationInstance.CompleteRequest(); The reason is that Response.End() throws a System.Threading.ThreadAbortException. It aborts a thread. If you have an exception logger, it will be littered with ThreadAbortExceptions, which in this case is expected behavior.

Intuitively, sending a CSV file to the browser should not raise an exception.

See here for more Is Response.End() considered harmful?

You can do it like this,

<input type="text" name="name" value="<?php echo $name;?>" />

But seen as you've taken it straight from user input, you want to sanitize it first so that nothing nasty is put into the output of your page.

<input type="text" name="name" value="<?php echo htmlspecialchars($name);?>" />

... or if you really want to use NOT IN you can use

SELECT * FROM match WHERE id NOT IN ( SELECT id FROM email WHERE id IS NOT NULL)

If I understand you right, we talk about a text file attachment. Thats unfortunate because if it was the email's message body, you could always use "\r\n", referring to http://www.faqs.org/rfcs/rfc822.html

But as it's an attachment, you must live with system differences. If I were in your shoes, I would choose one of those options:

a) only support windows clients by using "\r\n" as line end.

b) provide two attachment files, one with linux format and one with windows format.

c) I don't know if the attachment is to be read by people or machines, but if it is people I would consider attaching an HTML file instead of plain text. more portable and much prettier, too :)

3. Add this path to the Path envirement variable or edit PATH environment variable and add %APPDATA%\npm
4. Reopen cmd.

Add %APPDATA%\npm to front of Path, not end of the Path.

Try this in your script:

$("#YourElement").html(htmlData);

I do this in my table refreshment.

I had a similar problem: my default gradle wrapper was version 4.x, while the support for higher versions of Java has been added in Gradle 5.

I've updated my gradlew as described here: https://docs.gradle.org/current/userguide/gradle_wrapper.html#sec:upgrading_wrapper

TLTD:

./gradlew wrapper --gradle-version 5.6.2

gevang's answer is great. There's another way as well to do this directly by using pcolor. Code:

[X,Y] = meshgrid(-8:.5:8);
R = sqrt(X.^2 + Y.^2) + eps;
Z = sin(R)./R;
figure;
subplot(1,3,1);
pcolor(X,Y,Z); 
subplot(1,3,2);
pcolor(X,Y,Z); shading flat;
subplot(1,3,3);
pcolor(X,Y,Z); shading interp;

Output:

Also, pcolor is flat too, as show here (pcolor is the 2d base; the 3d figure above it is generated using mesh):

Using python to calculate this, for example(written in python 3), 50% transparency :

hex(round(256*0.50))

:)

This behaviour is terminal-specific and specified by the terminal emulator you use (e.g. xterm) and the semantics of terminal that it provides. The terminal behaviour has been very stable for the last 20 years, and you can reasonably rely on the semantics of \b.

Because it's more common to call range(0, 10) which returns [0,1,2,3,4,5,6,7,8,9] which contains 10 elements which equals len(range(0, 10)). Remember that programmers prefer 0-based indexing.

Also, consider the following common code snippet:

for i in range(len(li)):
    pass

Could you see that if range() went up to exactly len(li) that this would be problematic? The programmer would need to explicitly subtract 1. This also follows the common trend of programmers preferring for(int i = 0; i < 10; i++) over for(int i = 0; i <= 9; i++).

If you are calling range with a start of 1 frequently, you might want to define your own function:

>>> def range1(start, end):
...     return range(start, end+1)
...
>>> range1(1, 10)
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

If you want to stay with underscore so your predicate function can be more flexible, here are 2 ideas.

Method 1

Since the predicate for _.find receives both the value and index of an element, you can use side effect to retrieve the index, like this:

var idx;
_.find(tv, function(voteItem, voteIdx){ 
   if(voteItem.id == voteID){ idx = voteIdx; return true;}; 
});

Method 2

Looking at underscore source, this is how _.find is implemented:

_.find = _.detect = function(obj, predicate, context) {
  var result;
  any(obj, function(value, index, list) {
    if (predicate.call(context, value, index, list)) {
      result = value;
      return true;
    }
  });
  return result;
};

To make this a findIndex function, simply replace the line result = value; with result = index; This is the same idea as the first method. I included it to point out that underscore uses side effect to implement _.find as well.

Here lot of good answer but i think this will help someone

select id  from campaign where ( NOW() BETWEEN start_date AND end_date) 

In Java you can only import class Names, or static methods/fields.

To import class use

import full.package.name.of.SomeClass;

to import static methods/fields use

import static full.package.name.of.SomeClass.staticMethod;
import static full.package.name.of.SomeClass.staticField;

It allows for further querying further down the line. If this was beyond a service boundary say, then the user of this IQueryable object would be allowed to do more with it.

For instance if you were using lazy loading with nhibernate this might result in graph being loaded when/if needed.

You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:

import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values

... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.

Include an Setup Project (New Project > Other Project Types > Setup and Deployment > Visual Studio Installer) in your solution. It has options to include the framework installer. Check out this Deployment Guide MSDN post.

Just point to the dictionary at given key and assign a new value:

myDictionary[myKey] = myNewValue;

The command I use is:

diff -qr dir1/ dir2/

It is exactly the same as Mark's :) But his answer bothered me as it uses different types of flags, and it made me look twice. Using Mark's more verbose flags it would be:

diff  --brief --recursive dir1/ dir2/

_{I apologise for posting when the other answer is perfectly acceptable. Could not stop myself... working on being less pedantic.}

If you want to carry on using CSS3 selectors but need to support older browsers I would suggest using a polyfill such as Selectivizr.js

One liner to get local time information: struct tm *tinfo = localtime(&(time_t){time(NULL)});

HEAD is not the latest revision, it's the current revision. Usually, it's the latest revision of the current branch, but it doesn't have to be.

master is a name commonly given to the main branch, but it could be called anything else (or there could be no main branch).

origin is a name commonly given to the main remote. remote is another repository that you can pull from and push to. Usually it's on some server, like github.

Also for openCV in python you can do:

img = cv2.imread('myImage.jpg')
height, width, channels = img.shape 

Another way on the command line if you are using ant is to use the android.bat script (Windows) or android script (Mac). It's in $SDK_DIR/tools.

If you say,

android.bat update project --path .  --target "android-8"

it will regenerate your build.xml, AndroidManifest.xml, etc.

To ensure full Unicode support and reversibility, consider using:

'\n'.codePointAt(0);

This will ensure that when testing characters over the UTF-16 limit, you will get their true code point value.

e.g.

''.codePointAt(0); // 68181
String.fromCodePoint(68181); // ''

''.charCodeAt(0);  // 55298
String.fromCharCode(55298);  // '?'

When your are trying to apply prod on string type of value like:

['-214' '-153' '-58' ..., '36' '191' '-37']

you will get the error.

Solution: Append only integer value like [1,2,3], and you will get your expected output.

If the value is in string format before appending then, in the array you can convert the type into int type and store it in a list.

let's assume you are using shell=False and providing the command as a list. And some malicious user tried injecting an 'rm' command. You will see, that 'rm' will be interpreted as an argument and effectively 'ls' will try to find a file called 'rm'

>>> subprocess.run(['ls','-ld','/home','rm','/etc/passwd'])
ls: rm: No such file or directory
-rw-r--r--    1 root     root          1172 May 28  2020 /etc/passwd
drwxr-xr-x    2 root     root          4096 May 29  2020 /home
CompletedProcess(args=['ls', '-ld', '/home', 'rm', '/etc/passwd'], returncode=1)

shell=False is not a secure by default, if you don't control the input properly. You can still execute dangerous commands.

>>> subprocess.run(['rm','-rf','/home'])
CompletedProcess(args=['rm', '-rf', '/home'], returncode=0)
>>> subprocess.run(['ls','-ld','/home'])
ls: /home: No such file or directory
CompletedProcess(args=['ls', '-ld', '/home'], returncode=1)
>>>

I am writing most of my applications in container environments, I know which shell is being invoked and i am not taking any user input.

So in my use case, I see no security risk. And it is much easier creating long string of commands. Hope I am not wrong.

You are not breaking code over multiple lines, but rather a single identifier. There is a difference.

For your issue, try

R> setwd(paste("~/a/very/long/path/here",
               "/and/then/some/more",
               "/and/then/some/more",
               "/and/then/some/more", sep=""))

which also illustrates that it is perfectly fine to break code across multiple lines.

find all tabs and replaced by 4 spaces in notepad ++ .It worked.

Also consider java.text.MessageFormat, which uses a related syntax having numeric argument indexes. For example,

String aVariable = "of ponies";
String string = MessageFormat.format("A string {0}.", aVariable);

results in string containing the following:

A string of ponies.

More commonly, the class is used for its numeric and temporal formatting. An example of JFreeChart label formatting is described here; the class RCInfo formats a game's status pane.

Disabling the Sync to VBlank checkbox in nvidia-settings (OpenGL Settings tab) does the trick for me.

All links to the Azure Active Directory Connection page now seem to be invalid.

I had an older version of Azure AD installed too, this is what worked for me. Install this.

Run these in an elevated PS session:

uninstall-module AzureAD  # this may or may not be needed
install-module AzureAD
install-module AzureADPreview
install-module MSOnline

I was then able to log in and run what I needed.

To print your context ,you can write code like this :

FILE *fp;
char *of;
sprintf(of,"%s%s",text1,text2);
fp=fopen(of,'w');
fprintf(fp,"your print line");

This will return default size of text on button in pixels.

Kotlin

val size = Button(this).textSize

Java

float size = new Button(this).getTextSize();

See help(Sys.sleep).

For example, from ?Sys.sleep

testit <- function(x)
{
    p1 <- proc.time()
    Sys.sleep(x)
    proc.time() - p1 # The cpu usage should be negligible
}
testit(3.7)

Yielding

> testit(3.7)

html {
  min-height: 100%;
}

body {
  min-height: 100vh;
}

The html height (%) will take care of the height of the documents that's height is more than a 100% of the screen view while the body view height (vh) will take care of the document's height that is less than the height of the screen view.

I think the question is a little bit fuzzy - for example, it can be interpreted as a question about best practices in programming loops with if inside. So, I'll try to answer this question with this particular interpretation.

If you have if inside a loop, then in most cases you'd like to know how the loop has ended - was it "broken" by the if or was it ended "naturally"? So, your sample code can be modified in this way:

bool intMaxFound = false;
for (size = 0; size < HAY_MAX; size++)
{
  // wait for hay until EOF
  printf("\nhaystack[%d] = ", size);
  int straw = GetInt();
  if (straw == INT_MAX)
     {intMaxFound = true; break;}

  // add hay to stack
  haystack[size] = straw;
}
if (intMaxFound)
{
  // ... broken
}
else
{
  // ... ended naturally
}

The problem with this code is that the if statement is buried inside the loop body, and it takes some effort to locate it and understand what it does. A more clear (even without the break statement) variant will be:

bool intMaxFound = false;
for (size = 0; size < HAY_MAX && !intMaxFound; size++)
{
  // wait for hay until EOF
  printf("\nhaystack[%d] = ", size);
  int straw = GetInt();
  if (straw == INT_MAX)
     {intMaxFound = true; continue;}

  // add hay to stack
  haystack[size] = straw;
}
if (intMaxFound)
{
  // ... broken
}
else
{
  // ... ended naturally
}

In this case you can clearly see (just looking at the loop "header") that this loop can end prematurely. If the loop body is a multi-page text, written by somebody else, then you'd thank its author for saving your time.

UPDATE:

Thanks to SO - it has just suggested the already answered question about crash of the AT&T phone network in 1990. It's about a risky decision of C creators to use a single reserved word break to exit from both loops and switch.

Anyway this interpretation doesn't follow from the sample code in the original question, so I'm leaving my answer as it is.

I upgraded from Newtonsoft.Json 11.0.1 to 12.0.2. Opening the project file in Notepad++ I discovered both

<Reference Include="Newtonsoft.Json, Version=12.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed, processorArchitecture=MSIL">
      <HintPath>..\packages\Newtonsoft.Json.12.0.2\lib\net45\Newtonsoft.Json.dll</HintPath>
    </Reference>

and

<ItemGroup>
    <Reference Include="Newtonsoft.Json">
      <HintPath>..\packages\Newtonsoft.Json.11.0.1\lib\net45\Newtonsoft.Json.dll</HintPath>
    </Reference>
  </ItemGroup>

I deleted the ItemGroup wrapping the reference with the hint path to version 11.0.1.

These issues can be insanely frustrating to find. What's more, developers often follow the same steps as previous project setups. The prior setups didn't encounter the issue. For whatever reason the project file occasionally is updated incorrectly.

I desperately wish Microsoft would fix these visual studio DLL hell issues from popping up. It happens far too often and causing progress to screech to a halt until it is fixed, often by trial and error.

System.Data.SqlClient is the .NET Framework Data Provider for SQL Server. ie .NET library for SQL Server.

I don't know where providerName=SqlServer comes from. Could you be getting this confused with the provider keyword in your connection string? (I know I was :) )

In the web.config you should have the System.Data.SqlClient as the value of the providerName attribute. It is the .NET Framework Data Provider you are using.

<connectionStrings>
   <add 
      name="LocalSqlServer" 
      connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" 
      providerName="System.Data.SqlClient"
   />
</connectionStrings>

Split by ":" and return 1st part (port number don't needed, we want just IP):

netstat -tapen | grep "sshd: myusername" | head -n1 | awk '{split($5, a, ":"); print a[1]}'

Another way:

who am i | awk '{l = length($5) - 2; print substr($5, 2, l)}'

Feel free to use my form sheet controller MZFormSheetControllerfor iPhone, in example project there are many examples on how to present modal view controller which will not cover full window and has many presentation/transition styles.

You can also try newest version of MZFormSheetController which is called MZFormSheetPresentationController and have a lot of more features.

You could try the FLOOR function like this:

SELECT FLOOR(columnName), moreColumns, etc 
FROM myTable 
WHERE ... 

You could also try the FORMAT function, provided you know the decimal places can be omitted:

SELECT FORMAT(columnName,0), moreColumns, etc 
FROM myTable 
WHERE ... 

You could combine the two functions

SELECT FORMAT(FLOOR(columnName),0), moreColumns, etc 
FROM myTable 
WHERE ... 

Another way could be to import the module in a function. This way when the function completes the module gets garbage collected.

ADb used to work fine for me for a week. But now suddenly today it says the machine actively refused connection.

step 2: If it changed. Just use that new IP to connect.

Hope it helped someone :)

Please NOTE that this procedure of adding the reporting services described by @Rich Shealer above will be iterated every time you start a different project. In order to avoid that:

1. If you may need to set up a different computer (eg, at home without internet), then keep your downloaded installers from the marketplace somewhere safe, ie:

   • Microsoft.DataTools.ReportingServices.vsix, and
   • Microsoft.RdlcDesigner.vsix

2. Fetch the following libraries from the packages or bin folder of the application you have created with reporting services in it:

   • Microsoft.ReportViewer.Common.dll
   • Microsoft.ReportViewer.DataVisualization.dll
   • Microsoft.ReportViewer.Design.dll
   • Microsoft.ReportViewer.ProcessingObjectModel.dll
   • Microsoft.ReportViewer.WinForms.dll

3. Install the 2 components from 1 above

4. Add the dlls from 2 above as references (Project>References>Add...)
5. (Optional) Add Reporting tab to the toolbar
6. Add Items to Reporting tab
7. Browse to the bin folder or where you have the above dlls and add them

You are now good to go! ReportViewer icon will be added to your toolbar, and you will also now find Report and ReportWizard templates added to your Common list of templates when you want to add a New Item... (Report) to your project

NB: When set up using Nuget package manager, the Report and ReportWizard templates are grouped under Reporting. Using my method described above however does not add the Reporting grouping in installed templates, but I dont think it is any trouble given that it enables you to quickly integrate rdlc without internet and without downloading what you already have from Nuget every time!

InetAddress.getLocalHost().getHostName() is the best way out of the two as this is the best abstraction at the developer level.

Personally, I'd like to use range on a channel in a goroutine:

https://play.golang.org/p/qt48vvDu8cd

    "fmt"
    "sync"
)

func main() {
    var wg sync.WaitGroup
    c := make(chan bool)
    wg.Add(1)
    go func() {
        defer wg.Done()
        for b := range c {
            fmt.Printf("Hello %t\n", b)
        }
    }()
    c <- true
    c <- true
    close(c)
    wg.Wait()
}

SASS has a built-in rgba() function to evaluate values.

rgba($color, $alpha)

E.g.

rgba(#00aaff, 0.5) => rgba(0, 170, 255, 0.5)

An example using your own variables:

$my-color: #00aaff;
$my-opacity: 0.5;

.my-element {
  color: rgba($my-color, $my-opacity);
}

Outputs:

.my-element {
  color: rgba(0, 170, 255, 0.5);
}

MyComponent.customMethod('bar');  // true

I got same issue in Visual Studio 2017 and TFS 2017. DefaultCollection must be mapped first to you local path. Somehow this step was skipped and I got only MyFirstProject mapped.

All you need to do is:
- 1. Go to your TFS web page and remove the project from the server.

- 2. Remove the project from your local "Worksapces"

- 3. Go to "Manage Connections" which will refresh your Home page in TeamExplorer.

- 4. You will get Configuration page which will allow you to setup root path to your DefaultCollection.

- 5. You should get message that it been done successfully. Now you can create your project.

It's important to map root of your collection to your workspace first and then map a new project.

I ran across this article in the results returned by a search related to the IF command in a batch file, and I couldn't resist the opportunity to correct the misconception that IF blocks are limited to single commands. Following is a portion of a production Windows NT command script that runs daily on the machine on which I am composing this reply.

    if "%COPYTOOL%" equ "R" (
    WWLOGGER.exe "%APPDATA%\WizardWrx\%~n0.LOG" "Using RoboCopy to make a backup of %USERPROFILE%\My Documents\Outlook Files\*"
    %TOOLPATH% %SRCEPATH% %DESTPATH% /copyall %RCLOGSTR% /m /np /r:0 /tee
    C:\BIN\ExitCodeMapper.exe C:\BIN\ExitCodeMapper.INI[Robocopy] %TEMP%\%~n0.TMP %ERRORLEVEL%
) else (
    WWLOGGER.exe "%APPDATA%\WizardWrx\%~n0.LOG" "Using XCopy to make a backup of %USERPROFILE%\My Documents\Outlook Files\*"
    call %TOOLPATH%  "%USERPROFILE%\My Documents\Outlook Files\*" "%USERPROFILE%\My Documents\Outlook Files\_backups" /f /m /v /y
    C:\BIN\ExitCodeMapper.exe C:\BIN\ExitCodeMapper.INI[Xcopy] %TEMP%\%~n0.TMP %ERRORLEVEL%
)

Perhaps blocks of two or more lines applies exclusively to Windows NT command scripts (.CMD files), because a search of the production scripts directory of an application that is restricted to old school batch (.BAT) files, revealed only one-command blocks. Since the application has gone into extended maintenance (meaning that I am not actively involved in supporting it), I can't say whether that is because I didn't need more than one line, or that I couldn't make them work.

Regardless, if the latter is true, there is a simple workaround; move the multiple lines into either a separate batch file or a batch file subroutine. I know that the latter works in both kinds of scripts.

Use the Kafka consumer provided by Kafka :

bin/kafka-console-consumer.sh --bootstrap-server BROKERS --topic TOPIC_NAME

It will display the messages as it will receive it. Add --from-beginning if you want to start from the beginning.

I found the solution. Actually Base64 class is not available in Android. Link is given below for more information.

byte[] byteArray;                                                  
     byteArray= json.getBytes(StandardCharsets.US_ASCII);
    String encoded=Base64.encodeBytes(byteArray);
    userLogin(encoded);

Here is the link for Base64 class: http://androidcodemonkey.blogspot.com/2010/03/how-to-base64-encode-decode-android.html

Have you tried using the WebClient class?

you should be able to use

string result = "";
using (var client = new WebClient())
{
    client.Headers[HttpRequestHeader.ContentType] = "application/json"; 
    result = client.UploadString(url, "POST", json);
}
Console.WriteLine(result);

The Regular Expression Way

If you need stricter replacement matching, PostgreSQL's regexp_replace function can match using POSIX regular expression patterns. It has the syntax regexp_replace(source, pattern, replacement [, flags ]).

I will use flags i and g for case-insensitive and global matching, respectively. I will also use \m and \M to match the beginning and the end of a word, respectively.

There are usually quite a few gotchas when performing regex replacment. Let's see how easy it is to replace a cat with a dog.

SELECT regexp_replace('Cat bobcat cat cats catfish', 'cat', 'dog');
-->                    Cat bobdog cat cats catfish

SELECT regexp_replace('Cat bobcat cat cats catfish', 'cat', 'dog', 'i');
-->                    dog bobcat cat cats catfish

SELECT regexp_replace('Cat bobcat cat cats catfish', 'cat', 'dog', 'g');
-->                    Cat bobdog dog dogs dogfish

SELECT regexp_replace('Cat bobcat cat cats catfish', 'cat', 'dog', 'gi');
-->                    dog bobdog dog dogs dogfish

SELECT regexp_replace('Cat bobcat cat cats catfish', '\mcat', 'dog', 'gi');
-->                    dog bobcat dog dogs dogfish

SELECT regexp_replace('Cat bobcat cat cats catfish', 'cat\M', 'dog', 'gi');
-->                    dog bobdog dog cats catfish

SELECT regexp_replace('Cat bobcat cat cats catfish', '\mcat\M', 'dog', 'gi');
-->                    dog bobcat dog cats catfish

SELECT regexp_replace('Cat bobcat cat cats catfish', '\mcat(s?)\M', 'dog\1', 'gi');
-->                    dog bobcat dog dogs catfish

Even after all of that, there is at least one unresolved condition. For example, sentences that begin with "Cat" will be replaced with lower-case "dog" which break sentence capitalization.

Check out the current PostgreSQL pattern matching docs for all the details.

Update entire column with replacement text

Given my examples, maybe the safest option would be:

UPDATE table SET field = regexp_replace(field, '\mcat\M', 'dog', 'gi');

the command posted by Milad and Sandy did not work for me with mstsc. i had to add TERMSRV to the /generic switch. i found this information here: https://gist.github.com/jdforsythe/48a022ee22c8ec912b7e

cmdkey /generic:TERMSRV/<server> /user:<username> /pass:<password>

i could then use mstsc /v:<server> without getting prompted for the login.

The precedents answers didn't meet my needs.

If you want all files and dirs in one flat array, you can use this function (found here) :

// Does not support flag GLOB_BRACE        
function glob_recursive($pattern, $flags = 0) {
    $files = glob($pattern, $flags);
    foreach (glob(dirname($pattern).'/*', GLOB_ONLYDIR|GLOB_NOSORT) as $dir) {
        $files = array_merge($files, glob_recursive($dir.'/'.basename($pattern), $flags));
    }
    return $files;
}

In my case :

$paths = glob_recursive(os_path_join($base_path, $current_directory, "*"));

returns me an array like this :

[
'/home/dir',
'/home/dir/image.png',
'/home/dir/subdir',
'/home/dir/subdir/file.php',
]

You can also use dynamic path generation :

$paths = glob_recursive(os_path_join($base_path, $directory, "*"));

With this function :

function os_path_join(...$parts) {
  return preg_replace('#'.DIRECTORY_SEPARATOR.'+#', DIRECTORY_SEPARATOR, implode(DIRECTORY_SEPARATOR, array_filter($parts)));
}

If you wan get only directories you can use :

$paths = glob_recursive(os_path_join($base_path, $current_directory, "*"));
$subdirs = array_filter($paths, function($path) {
    return is_dir($path);
});

@FXML
ImageView image;

@Override
public void initialize(URL url, ResourceBundle rb) {
  image.setImage(new Image ("/about.jpg"));
}

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

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

I am extending Michaels answer to address your question.

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

Expaination

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

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

3. Now use that value to set maxInactiveInterval

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

   a. Copy configured value to static variable globalSessionTimeoutInterval.

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

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

Logical code for achieving the same

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

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

  public void sessionDestroyed(HttpSessionEvent event) {}

}

And in your Configuration Controller or Configuration servlet

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

$("#bchange").click(function() {
    $("body, this").css("background-color","yellow");
});

Gesture Recognizers

There are a number of commonly used touch events (or gestures) that you can be notified of when you add a Gesture Recognizer to your view. They following gesture types are supported by default:

• UITapGestureRecognizer Tap (touching the screen briefly one or more times)
• UILongPressGestureRecognizer Long touch (touching the screen for a long time)
• UIPanGestureRecognizer Pan (moving your finger across the screen)
• UISwipeGestureRecognizer Swipe (moving finger quickly)
• UIPinchGestureRecognizer Pinch (moving two fingers together or apart - usually to zoom)
• UIRotationGestureRecognizer Rotate (moving two fingers in a circular direction)

In addition to these, you can also make your own custom gesture recognizer.

Adding a Gesture in the Interface Builder

Drag a gesture recognizer from the object library onto your view.

Control drag from the gesture in the Document Outline to your View Controller code in order to make an Outlet and an Action.

This should be set by default, but also make sure that User Action Enabled is set to true for your view.

Adding a Gesture Programmatically

To add a gesture programmatically, you (1) create a gesture recognizer, (2) add it to a view, and (3) make a method that is called when the gesture is recognized.

import UIKit
class ViewController: UIViewController {

    @IBOutlet weak var myView: UIView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 1. create a gesture recognizer (tap gesture)
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTap(sender:)))
        
        // 2. add the gesture recognizer to a view
        myView.addGestureRecognizer(tapGesture)
    }
    
    // 3. this method is called when a tap is recognized
    @objc func handleTap(sender: UITapGestureRecognizer) {
        print("tap")
    }
}

Notes

• The sender parameter is optional. If you don't need a reference to the gesture then you can leave it out. If you do so, though, remove the (sender:) after the action method name.
• The naming of the handleTap method was arbitrary. Name it whatever you want using action: #selector(someMethodName(sender:)).

More Examples

You can study the gesture recognizers that I added to these views to see how they work.

Here is the code for that project:

import UIKit
class ViewController: UIViewController {
    
    @IBOutlet weak var tapView: UIView!
    @IBOutlet weak var doubleTapView: UIView!
    @IBOutlet weak var longPressView: UIView!

    @IBOutlet weak var swipeView: UIView!
    @IBOutlet weak var pinchView: UIView!
    @IBOutlet weak var rotateView: UIView!
    @IBOutlet weak var label: UILabel!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Tap
        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTap))
        tapView.addGestureRecognizer(tapGesture)
        
        // Double Tap
        let doubleTapGesture = UITapGestureRecognizer(target: self, action: #selector(handleDoubleTap))
        doubleTapGesture.numberOfTapsRequired = 2
        doubleTapView.addGestureRecognizer(doubleTapGesture)
        
        // Long Press
        let longPressGesture = UILongPressGestureRecognizer(target: self, action: #selector(handleLongPress(gesture:)))
        longPressView.addGestureRecognizer(longPressGesture)
        
        // Pan
        let panGesture = UIPanGestureRecognizer(target: self, action: #selector(handlePan(gesture:)))
        panView.addGestureRecognizer(panGesture)

        }
    }

Notes

• You can add multiple gesture recognizers to a single view. For the sake of simplicity, though, I didn't do that (except for the swipe gesture). If you need to for your project, you should read the gesture recognizer documentation. It is fairly understandable and helpful.
• Known issues with my examples above: (1) Pan view resets its frame on next gesture event. (2) Swipe view comes from the wrong direction on the first swipe. (These bugs in my examples should not affect your understanding of how Gestures Recognizers work, though.)

Both are the element operators and they are used to select a single element from a sequence. But there is a minor difference between them. SingleOrDefault() operator would throw an exception if more than one elements are satisfied the condition where as FirstOrDefault() will not throw any exception for the same. Here is the example.

List<int> items = new List<int>() {9,10,9};
//Returns the first element of a sequence after satisfied the condition more than one elements
int result1 = items.Where(item => item == 9).FirstOrDefault();
//Throw the exception after satisfied the condition more than one elements
int result3 = items.Where(item => item == 9).SingleOrDefault();

it is Cross-site scripting problem. Common modern browsers doesn't allow to send request to another url.

In response to @Zxaos request, since we can not have AND/OR operators for MySQL triggers, starting with your code, below is a complete example to achieve the same.

1. Define the INSERT trigger:

DELIMITER //
DROP TRIGGER IF EXISTS my_insert_trigger//
CREATE DEFINER=root@localhost TRIGGER my_insert_trigger
    AFTER INSERT ON `table`
    FOR EACH ROW

BEGIN
    -- Call the common procedure ran if there is an INSERT or UPDATE on `table`
    -- NEW.id is an example parameter passed to the procedure but is not required
    -- if you do not need to pass anything to your procedure.
    CALL procedure_to_run_processes_due_to_changes_on_table(NEW.id);
END//
DELIMITER ;

2. Define the UPDATE trigger

DELIMITER //
DROP TRIGGER IF EXISTS my_update_trigger//

CREATE DEFINER=root@localhost TRIGGER my_update_trigger
    AFTER UPDATE ON `table`
    FOR EACH ROW
BEGIN
    -- Call the common procedure ran if there is an INSERT or UPDATE on `table`
    CALL procedure_to_run_processes_due_to_changes_on_table(NEW.id);
END//
DELIMITER ;

3. Define the common PROCEDURE used by both these triggers:

DELIMITER //
DROP PROCEDURE IF EXISTS procedure_to_run_processes_due_to_changes_on_table//

CREATE DEFINER=root@localhost PROCEDURE procedure_to_run_processes_due_to_changes_on_table(IN table_row_id VARCHAR(255))
READS SQL DATA
BEGIN

    -- Write your MySQL code to perform when a `table` row is inserted or updated here

END//
DELIMITER ;

You note that I take care to restore the delimiter when I am done with my business defining the triggers and procedure.

This works:

$('.scroll').on("click", function(e) {

  e.preventDefault();

  var dest = $(this).attr("href");

  $("html, body").animate({

    'scrollTop':   $(dest).offset().top

  }, 2000);

});

https://jsfiddle.net/68pnkfgd/

Just add the class 'scroll' to any links you wish to animate

You have to access to your class atributes.

To access to it atributes, you have to do:

person.id
person.name

where

person

is an instance of your class Person.

This can be done if the attibutes can be accessed, if not, you must use setters and getters...

You should not use jQuery in Angular. While it is possible (see other answers for this question), it is discouraged. Why?

Angular holds an own representation of the DOM in its memory and doesn't use query-selectors (functions like document.getElementById(id)) like jQuery. Instead all the DOM-manipulation is done by Renderer2 (and Angular-directives like *ngFor and *ngIf accessing that Renderer2 in the background/framework-code). If you manipulate DOM with jQuery yourself you will sooner or later...

1. Run into synchronization problems and have things wrongly appearing or not disappearing at the right time from your screen
2. Have performance issues in more complex components, as Angular's internal DOM-representation is bound to zone.js and its change detection-mechanism - so updating the DOM manually will always block the thread your app is running on.
3. Have other confusing errors you don't know the origin of.
4. Not being able to test the application correctly (Jasmine requires you to know when elements have been rendered)
5. Not being able to use Angular Universal or WebWorkers

If you really want to include jQuery (for duck-taping some prototype that you will 100% definitively throw away), I recommend to at least include it in your package.json with npm install --save jquery instead of getting it from google's CDN.

TLDR: For learning how to manipulate the DOM in the Angular way please go through the official tour-of heroes tutorial first: https://angular.io/tutorial/toh-pt2 If you need to access elements higher up in the DOM hierarchy (parent or document body) or for some other reason directives like *ngIf, *ngFor, custom directives, pipes and other angular utilities like [style.background], [class.myOwnCustomClass] don't satisfy your needs, use Renderer2: https://www.concretepage.com/angular-2/angular-4-renderer2-example

Yes.

Add DisableCacheViewer Registry Key

Create a new dword key under HKLM\Software\Microsoft\Fusion\ with the name DisableCacheViewer and set it’s [DWORD] value to 1.

Go back to Windows Explorer to the assembly folder and it will be the normal file system view.

I think using visual block mode is a better and more versatile method for dealing with this type of thing. Here's an example:

This is the First line.  
This is the second.  
The third.

To insert " Hello world." (space + clipboard) at the end of each of these lines:

• On a character in the first line, press Ctrl-V (or Ctrl-Q if Ctrl-V is paste).
• Press jj to extend the visual block over three lines.
• Press $ to extend the visual block to the end of each line. Press A then space then type Hello world. + then Esc.

The result is:

This is the First line. Hello world.  
This is the second. Hello world.  
The third. Hello world.  

(example from Vim.Wikia.com)

maybe this will help (rotate 90 degree)(this worked for me)

private Bitmap rotateBitmap(Bitmap image){
        int width=image.getHeight();
        int height=image.getWidth();

        Bitmap srcBitmap=Bitmap.createBitmap(width, height, image.getConfig());

        for (int y=width-1;y>=0;y--)
            for(int x=0;x<height;x++)
                srcBitmap.setPixel(width-y-1, x,image.getPixel(x, y));
        return srcBitmap;

    }

If Sheets("Sheet1").OLEObjects("CheckBox1").Object.Value = True Then

I believe Tim is right. You have a Form Control. For that you have to use this

If ActiveSheet.Shapes("Check Box 1").ControlFormat.Value = 1 Then

You can't achieve POST requests using urllib (only for GET), instead try using requests module, e.g.:

Example 1.0:

import requests

base_url="www.server.com"
final_url="/{0}/friendly/{1}/url".format(base_url,any_value_here)

payload = {'number': 2, 'value': 1}
response = requests.post(final_url, data=payload)

print(response.text) #TEXT/HTML
print(response.status_code, response.reason) #HTTP

Example 1.2:

>>> import requests

>>> payload = {'key1': 'value1', 'key2': 'value2'}

>>> r = requests.post("http://httpbin.org/post", data=payload)
>>> print(r.text)
{
  ...
  "form": {
    "key2": "value2",
    "key1": "value1"
  },
  ...
}

Example 1.3:

>>> import json

Yes, it is a non-type parameter. You can have several kinds of template parameters

• Type Parameters.
  • Types
  • Templates (only classes and alias templates, no functions or variable templates)
• Non-type Parameters
  • Pointers
  • References
  • Integral constant expressions

What you have there is of the last kind. It's a compile time constant (so-called constant expression) and is of type integer or enumeration. After looking it up in the standard, i had to move class templates up into the types section - even though templates are not types. But they are called type-parameters for the purpose of describing those kinds nonetheless. You can have pointers (and also member pointers) and references to objects/functions that have external linkage (those that can be linked to from other object files and whose address is unique in the entire program). Examples:

Template type parameter:

template<typename T>
struct Container {
    T t;
};

// pass type "long" as argument.
Container<long> test;

Template integer parameter:

template<unsigned int S>
struct Vector {
    unsigned char bytes[S];
};

// pass 3 as argument.
Vector<3> test;

Template pointer parameter (passing a pointer to a function)

template<void (*F)()>
struct FunctionWrapper {
    static void call_it() { F(); }
};

// pass address of function do_it as argument.
void do_it() { }
FunctionWrapper<&do_it> test;

Template reference parameter (passing an integer)

template<int &A>
struct SillyExample {
    static void do_it() { A = 10; }
};

// pass flag as argument
int flag;
SillyExample<flag> test;

Template template parameter.

template<template<typename T> class AllocatePolicy>
struct Pool {
    void allocate(size_t n) {
        int *p = AllocatePolicy<int>::allocate(n);
    }
};

// pass the template "allocator" as argument. 
template<typename T>
struct allocator { static T * allocate(size_t n) { return 0; } };
Pool<allocator> test;

A template without any parameters is not possible. But a template without any explicit argument is possible - it has default arguments:

template<unsigned int SIZE = 3>
struct Vector {
    unsigned char buffer[SIZE];
};

Vector<> test;

Syntactically, template<> is reserved to mark an explicit template specialization, instead of a template without parameters:

template<>
struct Vector<3> {
    // alternative definition for SIZE == 3
};

JavaScript Classes and Inheritance (ES6)

According to ES6, you can use JavaScript classes and inheritance to accomplish what you need.

JavaScript classes, introduced in ECMAScript 2015, are primarily syntactical sugar over JavaScript's existing prototype-based inheritance.

Reference: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes

First of all, we define our abstract class. This class can't be instantiated, but can be extended. We can also define functions that must be implemented in all classes that extends this one.

/**
 * Abstract Class Animal.
 *
 * @class Animal
 */
class Animal {

  constructor() {
    if (this.constructor == Animal) {
      throw new Error("Abstract classes can't be instantiated.");
    }
  }

  say() {
    throw new Error("Method 'say()' must be implemented.");
  }

  eat() {
    console.log("eating");
  }
}

After that, we can create our concrete Classes. These classes will inherit all functions and behaviour from abstract class.

/**
 * Dog.
 *
 * @class Dog
 * @extends {Animal}
 */
class Dog extends Animal {
  say() {
    console.log("bark");
  }
}

/**
 * Cat.
 *
 * @class Cat
 * @extends {Animal}
 */
class Cat extends Animal {
  say() {
    console.log("meow");
  }
}

/**
 * Horse.
 *
 * @class Horse
 * @extends {Animal}
 */
class Horse extends Animal {}

And the results...

// RESULTS

new Dog().eat(); // eating
new Cat().eat(); // eating
new Horse().eat(); // eating

new Dog().say(); // bark
new Cat().say(); // meow
new Horse().say(); // Error: Method say() must be implemented.

new Animal(); // Error: Abstract classes can't be instantiated.

The task must be configured in two steps.

First you create a simple task that start at 0:00, every day. Then, you go in Advanced... (or similar depending on the operating system you are on) and select the Repeat every X minutes option for 24 hours.

The key here is to find the advanced properties. If you are using the XP wizard, it will only offer you to launch the advanced dialog once you created the task.

On more recent versions of Windows (7+ I think?):

1. Double click the task and a property window will show up.
2. Click the Triggers tab.
3. Double click the trigger details and the Edit Trigger window will show up.
4. Under Advanced settings panel, tick Repeat task every xxx minutes, and set Indefinitely if you need.
5. Finally, click ok.

You may also use the stringr package

library(dplyr)
library(stringr)
My.Data %>% filter(str_detect(x, '^G45'))

You may not use '^' (starts with) in this case, to obtain the results you need

PHP 7 is already worked on such memory management issues and its reduced up-to minimal usage.

<?php
  $start = microtime(true);
  for ($i = 0; $i < 10000000; $i++) {
    $a = 'a';
    $a = NULL;
  }
  $elapsed = microtime(true) - $start;

  echo "took $elapsed seconds\r\n";

  $start = microtime(true);
  for ($i = 0; $i < 10000000; $i++) {
     $a = 'a';
     unset($a);
  }
  $elapsed = microtime(true) - $start;

  echo "took $elapsed seconds\r\n";

?>

PHP 7.1 Outpu:

took 0.16778993606567 seconds took 0.16630101203918 seconds

Without changing the position to absolute, see below. This supports all recent browsers as well.

.vranger {_x000D_
  margin-top: 50px;_x000D_
   transform: rotate(270deg);_x000D_
  -moz-transform: rotate(270deg); /*do same for other browsers if required*/_x000D_
}

<input type="range" class="vranger"/>

for very old browsers, you can use -sand-transform: rotate(10deg); from CSS sandpaper

or use

prefix selector such as -ms-transform: rotate(270deg); for IE9

vector<char> toVector( const std::string& s ) {
  string s = "apple";  
  vector<char> v(s.size()+1);
  memcpy( &v.front(), s.c_str(), s.size() + 1 );
  return v;
}
vector<char> v = toVector(std::string("apple"));

// what you were looking for (mutable)
char* c = v.data();

.c_str() works for immutable. The vector will manage the memory for you.

Well, I made a simple two liner script for this, Its small and does what u want.

Check it http://jsfiddle.net/9RxLM/

Its a jquery solution :D

Use this CSS (jsFiddle example):

input:disabled.btn:hover,
input:disabled.btn:active,
input:disabled.btn:focus {
  color: green
}

You have to write the most outer element on the left and the most inner element on the right.

.btn:hover input:disabled would select any disabled input elements contained in an element with a class btn which is currently hovered by the user.

I would prefer :disabled over [disabled], see this question for a discussion: Should I use CSS :disabled pseudo-class or [disabled] attribute selector or is it a matter of opinion?

By the way, Laravel (PHP) generates the HTML - not the browser.

You can write the where clause as:

where (case when (:stateCode = '') then (1)
            when (:stateCode != '') and (vw.state_cd in (:stateCode)) then 1
            else 0)
       end) = 1;

Alternatively, remove the case entirely:

where (:stateCode = '') or
      ((:stateCode != '') and vw.state_cd in (:stateCode));

Or, even better:

where (:stateCode = '') or vw.state_cd in (:stateCode)

I like PyInstaller - especially the "windowed" variant:

pyinstaller --onefile --windowed myscript.py

It will create one single *.exe file in a distination/folder.

The normalize function from the BBMisc package was the right tool for me since it can deal with NA values.

Here is how to use it:

Given the following dataset,

    ASR_API     <- c("CV",  "F",    "IER",  "LS-c", "LS-o")
    Human       <- c(NA,    5.8,    12.7,   NA, NA)
    Google      <- c(23.2,  24.2,   16.6,   12.1,   28.8)
    GoogleCloud <- c(23.3,  26.3,   18.3,   12.3,   27.3)
    IBM     <- c(21.8,  47.6,   24.0,   9.8,    25.3)
    Microsoft   <- c(29.1,  28.1,   23.1,   18.8,   35.9)
    Speechmatics    <- c(19.1,  38.4,   21.4,   7.3,    19.4)
    Wit_ai      <- c(35.6,  54.2,   37.4,   19.2,   41.7)
    dt     <- data.table(ASR_API,Human, Google, GoogleCloud, IBM, Microsoft, Speechmatics, Wit_ai)
> dt

normalized values can be obtained like this:

(normalizedHuman is made a list of NAs ...)

regarding the selection of specific columns for calculation, a generic method can be employed like this one:

data_vars <- df_full %>% dplyr::select(-ASR_API,-otherVarNotToBeUsed)
meta_vars <- df_full %>% dplyr::select(ASR_API,otherVarNotToBeUsed)
data_varsn <- normalize(data_vars, method = "standardize", range = c(0, 1), margin = 1L, on.constant = "quiet")
dtn <- cbind(meta_vars,data_varsn)

use

   statusCode: {
    404: function() {
      alert('page not found');
    }
  }

-

$.ajax({
    type: 'POST',
    url: '/controller/action',
    data: $form.serialize(),
    success: function(data){
        alert('horray! 200 status code!');
    },
    statusCode: {
    404: function() {
      alert('page not found');
    },

    400: function() {
       alert('bad request');
   }
  }

});

It IS possible, using something like the below example that I put together with the help of work from (https://gist.github.com/bitinn/1700068a276fb29740a7) that didn't quite work on iOS 11:

Here's the modified code that works on iOS 11.03, please comment if it worked for you.

Whenever there are issues of mismatched axis limits, the right tool in base graphics is to use matplot. The key is to leverage the from and to arguments to density.default. It's a bit hackish, but fairly straightforward to roll yourself:

set.seed(102349)
x1 = rnorm(1000, mean = 5, sd = 3)
x2 = rnorm(5000, mean = 2, sd = 8)

xrng = range(x1, x2)

#force the x values at which density is
#  evaluated to be the same between 'density'
#  calls by specifying 'from' and 'to'
#  (and possibly 'n', if you'd like)
kde1 = density(x1, from = xrng[1L], to = xrng[2L])
kde2 = density(x2, from = xrng[1L], to = xrng[2L])

matplot(kde1$x, cbind(kde1$y, kde2$y))

Add bells and whistles as desired (matplot accepts all the standard plot/par arguments, e.g. lty, type, col, lwd, ...).
