With Java 7 and later version, you can specify a byte literal in this way: byte aByte = (byte)0b00100001;

Reference: http://docs.oracle.com/javase/8/docs/technotes/guides/language/binary-literals.html

Taken from here and it worked for me :

1.Go to IIS Manager.

2.Click on your app.

3.Go to "Handler Mappings".

4.In the feature list, double click on "WebDAV".

5.Click on "Request Restrictions".

6.In the tab "Verbs" select "All verbs" .

7.Press OK.

For Photoshop you need to download Photoshop portable.... Load image e press "w" click in image e suave as png or gif....

It can be solved by using different attribute.

• Use the cell Control click event.
• Select the column value that your transpose to anther column.
• send the selected value to the another text box or level whatever you fill convenient and a complementary button to modify the selected property.
• update the whole stack op the database and make a algorithm with sql query to overcome this one to transpose it into the another column.

Read it in by row and then transpose it in the command line. If you're using Unix, install csvtool and follow the directions in: https://unix.stackexchange.com/a/314482/186237

The one time I wrote a singleton in Python I used a class where all the member functions had the classmethod decorator.

class foo:
  x = 1

  @classmethod
  def increment(cls, y = 1):
    cls.x += y

You can pass in the hostname as an environment variable. You could also mount /etc so you can cat /etc/hostname. But I agree with Vitaly, this isn't the intended use case for containers IMO.

Instead of Creating New Application Pool,You can go to your Existing application Pool->Right click Advance setting->Enable 32-bit Application-----Set to TRUE

For anyone else out there wondering how to do this, I have the following solution for SQL Server 2008 R2 and later:

USE master
go
DENY VIEW ANY DATABASE TO [user]
go

This will address exactly the requirement outlined above..

No comment on why you want to do this, or what might be a more standard practice: here is a solution to your question.... Keep in mind that the type of quotes required by your command line may vary.

In your db.js, export the init function. There are many ways, but for example:

module.exports.init = function () {
  console.log('hi');
};

Then call it like this, assuming your db.js is in the same directory as your command prompt:

node -e 'require("./db").init()'

To other readers, the OP's init function could have been called anything, it is not important, it is just the specific name used in the question.

I have managed to get my PDA working properly with Windows 10.

For transparency when I posted the original question I had upgraded a Windows 8.1 PC to Windows 10, I have since moved to using a different PC that had a clean Windows 10 installation.

These are the steps I followed to solve the problem:

• First of all I installed Visual Studio 2008.
• Then I installed Microsoft Windows Mobile Device Center 6.1
  • http://www.microsoft.com/en-us/download/details.aspx?id=3182
• Then Windows Mobile 6 Professional and Standard Software Development Kits Refresh
  • http://www.microsoft.com/en-us/download/details.aspx?id=6135
• Then Windows Mobile 6.5 Developer Tool Kit
  • http://www.microsoft.com/en-us/download/details.aspx?id=17284
• Finally I opened up the Mobile Device Center, went to Mobile Device Settings -> Connection Settings and made sure DMA was selected under "Allow connections to one of the following"

index.html

<input id="suby" type="submit" value="Remove DUMMY"/>

myscripts.js

document.addEventListener("DOMContentLoaded", {
//Do this AFTER elements are loaded

    document.getElementById("suby").addEventListener("click", e => {
        document.getElementById("dummy").remove()
    })

})

Alternatively, by changing a line of the above code:

# df.date = df.date.apply(lambda d: datetime.strptime(d, "%Y-%m-%d"))
df.date = df.date.apply(lambda d: datetime.datetime.fromtimestamp(int(d)).strftime('%Y-%m-%d'))

It should also work.

A little late here, but I've found this to be a common problem worth a custom directive to handle. Here's how that might look:

  .directive('toggleOnHover', function(){
    return {
      restrict: 'A',
      link: link
    };

    function link(scope, elem, attrs){
      elem.on('mouseenter', applyToggleExp);
      elem.on('mouseleave', applyToggleExp);

      function applyToggleExp(){
        scope.$apply(attrs.toggleOnHover);
      }
    }

  });

You can use it like this:

<li toggle-on-hover="editableProp = !editableProp">edit</li> 

EL expression:

${requestScope.Error_Message}

There are several implicit objects in JSP EL. See Expression Language under the "Implicit Objects" heading.

Assuming they are all defined in the same assembly, you can do:

IEnumerable<AbstractDataExport> exporters = typeof(AbstractDataExport)
    .Assembly.GetTypes()
    .Where(t => t.IsSubclassOf(typeof(AbstractDataExport)) && !t.IsAbstract)
    .Select(t => (AbstractDataExport)Activator.CreateInstance(t));

If you like Vim, it has built-in syntax highlighting for the syslog file, e.g. it will highlight error messages in red.

vi +'syntax on' /var/log/syslog

Use the length() method in the File class. From the javadocs:

Returns the length of the file denoted by this abstract pathname. The return value is unspecified if this pathname denotes a directory.

UPDATED Nowadays we should use the Files.size() method:

Paths path = Paths.get("/path/to/file");
long size = Files.size(path);

For the second part of the question, straight from File's javadocs:

• getUsableSpace() Returns the number of bytes available to this virtual machine on the partition named by this abstract pathname

• getTotalSpace() Returns the size of the partition named by this abstract pathname

• getFreeSpace() Returns the number of unallocated bytes in the partition named by this abstract path name

I know this is an old post but I am having the same problem and I solved it this way

$current_request = preg_replace("/\?.*$/","",$_SERVER["REQUEST_URI"]);

Or equivalently

$current_request = preg_replace("/\?.*/D","",$_SERVER["REQUEST_URI"]);

Your code "for /f "tokens=* delims=" %%x in (a.txt) do echo %%x" will work on most Windows Operating Systems unless you have modified commands.

So you could instead "cd" into the directory to read from before executing the "for /f" command to follow out the string. For instance if the file "a.txt" is located at C:\documents and settings\%USERNAME%\desktop\a.txt then you'd use the following.

cd "C:\documents and settings\%USERNAME%\desktop"
for /f "tokens=* delims=" %%x in (a.txt) do echo %%x
echo.
echo.
echo.
pause >nul
exit

But since this doesn't work on your computer for x reason there is an easier and more efficient way of doing this. Using the "type" command.

@echo off
color a
cls
cd "C:\documents and settings\%USERNAME%\desktop"
type a.txt
echo.
echo.
pause >nul
exit

Or if you'd like them to select the file from which to write in the batch you could do the following.

@echo off
:A
color a
cls
echo Choose the file that you want to read.
echo.
echo.
tree
echo.
echo.
echo.
set file=
set /p file=File:
cls
echo Reading from %file%
echo.
type %file%
echo.
echo.
echo.
set re=
set /p re=Y/N?:
if %re%==Y goto :A
if %re%==y goto :A
exit

There is a typo error :

$('#activelist :checkbox')...

Should be :

$('#inactivelist:checkbox')...

Here's a helpful article on long polling (long-held HTTP request) using jQuery. A code snippet derived from this article:

(function poll() {
    setTimeout(function() {
        $.ajax({
            url: "/server/api/function",
            type: "GET",
            success: function(data) {
                console.log("polling");
            },
            dataType: "json",
            complete: poll,
            timeout: 2000
        })
    }, 5000);
})();

This will make the next request only after the ajax request has completed.

A variation on the above that will execute immediately the first time it is called before honouring the wait/timeout interval.

(function poll() {
    $.ajax({
        url: "/server/api/function",
        type: "GET",
        success: function(data) {
            console.log("polling");
        },
        dataType: "json",
        complete: setTimeout(function() {poll()}, 5000),
        timeout: 2000
    })
})();

See the example code and demo at the bottom of the jquery documentation page:

http://api.jquery.com/mouseenter/

... mouseover fires when the pointer moves into the child element as well, while mouseenter fires only when the pointer moves into the bound element.

I just did this -

 $("#myform").bind('ajax:complete', function() {

         // tasks to do 


   });

And things worked perfectly .

See this api documentation for more specific details.

There's a great look at this on the wikipedia article.

It even has a nice plot of complexity for value pairs.

It is not O(a%b).

It is known (see article) that it will never take more steps than five times the number of digits in the smaller number. So the max number of steps grows as the number of digits (ln b). The cost of each step also grows as the number of digits, so the complexity is bound by O(ln^2 b) where b is the smaller number. That's an upper limit, and the actual time is usually less.

I wrote two programs:

int main(){return 0;}

and

#include <stdlib.h>
int main(){exit(0)}

After executing gcc -S -O1. Here what I found watching at assembly (only important parts):

main:
    movl    $0, %eax    /* setting return value */
    ret                 /* return from main */

and

main:
    subq    $8, %rsp    /* reserving some space */
    movl    $0, %edi    /* setting return value */
    call    exit        /* calling exit function */
                        /* magic and machine specific wizardry after this call */

So my conclusion is: use return when you can, and exit() when you need.

You can use Collections.sort as follows:

private static void order(List<Person> persons) {

    Collections.sort(persons, new Comparator() {

        public int compare(Object o1, Object o2) {

            String x1 = ((Person) o1).getName();
            String x2 = ((Person) o2).getName();
            int sComp = x1.compareTo(x2);

            if (sComp != 0) {
               return sComp;
            } 

            Integer x1 = ((Person) o1).getAge();
            Integer x2 = ((Person) o2).getAge();
            return x1.compareTo(x2);
    }});
}

List<Persons> is now sorted by name, then by age.

String.compareTo "Compares two strings lexicographically" - from the docs.

Collections.sort is a static method in the native Collections library. It does the actual sorting, you just need to provide a Comparator which defines how two elements in your list should be compared: this is achieved by providing your own implementation of the compare method.

Before going offline you have to make sure that everything is in your local repo, which is required while working offline. Running "mvn dependency:go-offline" for the project(s)/pom(s), you intend to work on, will reduce the efforts to achieve this.

But it´s usually not the whole story, because dependency:go-offline will only download the "bare build" plugins (go-offline / resolve-plugins does not resolve all plugin dependencies). So you have to find a way to download deploy / test / site plugins (and maybe others) and their dependencies into your repo.

Furthermore dependency:go-offline does not download the pom´s artifact itself, so you have to dependency:copy it if required.

Sometimes - as MaDa wrote - you do not know, what you will need, while being offline, which makes it pretty impossible to have a "sufficient" repo.

Anyway having a properly filled repo you only have to add "<offline>true</offline>" to Maven´s settings.xml to go offline.

Do not change the Maven profile (id) you used to fill your repo, while being offline. Maven recognizes the downloaded artifacts in its metadata with an "identity", which is bound to the profile id.

I think the issue is that you've got it just a little upside down.

public class AuroraClient : IAuroraClient
{
    private readonly HttpClient _client;

    public AuroraClient() : this(new HttpClientHandler())
    {
    }

    public AuroraClient(HttpMessageHandler messageHandler)
    {
        _client = new HttpClient(messageHandler);
    }
}

If you look at the class above, I think this is what you want. Microsoft recommends keeping the client alive for optimal performance, so this type of structure allows you to do that. Also the HttpMessageHandler is an abstract class and therefore mockable. Your test method would then look like this:

[TestMethod]
public void TestMethod1()
{
    // Arrange
    var mockMessageHandler = new Mock<HttpMessageHandler>();
    // Set up your mock behavior here
    var auroraClient = new AuroraClient(mockMessageHandler.Object);
    // Act
    // Assert
}

This allows you to test your logic while mocking the HttpClient's behavior.

Sorry guys, after writing this and trying it myself, I realized that you can't mock the protected methods on the HttpMessageHandler. I subsequently added the following code to allow for injection of a proper mock.

public interface IMockHttpMessageHandler
{
    Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken);
}

public class MockHttpMessageHandler : HttpMessageHandler
{
    private readonly IMockHttpMessageHandler _realMockHandler;

    public MockHttpMessageHandler(IMockHttpMessageHandler realMockHandler)
    {
        _realMockHandler = realMockHandler;
    }

    protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        return await _realMockHandler.SendAsync(request, cancellationToken);
    }
}

The tests written with this then look something like the following:

[TestMethod]
public async Task GetProductsReturnsDeserializedXmlXopData()
{
    // Arrange
    var mockMessageHandler = new Mock<IMockHttpMessageHandler>();
    // Set up Mock behavior here.
    var client = new AuroraClient(new MockHttpMessageHandler(mockMessageHandler.Object));
    // Act
    // Assert
}

Another way to solve this problem (it's not so good practice but looks beauty):

static class Helper
{
    public static object AsSingleParam(this object[] arg)
    {
       return (object)arg;
    }
}

Usage:

f(new object[] { 1, 2, 3 }.AsSingleParam());

Website URL:

http://www.example.com/?id=2

Code:

$id = intval($_GET['id']);
$results = mysql_query("SELECT * FROM next WHERE id=$id");    
while ($row = mysql_fetch_array($results))     
{       
    $url = $row['url'];
    echo $url; //Outputs: 2
}

Old question, but an easy way is to:

• Iterate through file, adding each line to an new array list
• iterate through the array, find matching String, then call the remove method.
• iterate through array again, printing each line to the file, boolean for append should be false, which basically replaces the file

Solution #1 (Older) (not recommended)

Firstly install ffmpeg-php project (http://ffmpeg-php.sourceforge.net/)

And then you can use of this simple code:

<?php
$frame = 10;
$movie = 'test.mp4';
$thumbnail = 'thumbnail.png';

$mov = new ffmpeg_movie($movie);
$frame = $mov->getFrame($frame);
if ($frame) {
    $gd_image = $frame->toGDImage();
    if ($gd_image) {
        imagepng($gd_image, $thumbnail);
        imagedestroy($gd_image);
        echo '<img src="'.$thumbnail.'">';
    }
}
?>

Description: This project use binary extension .so file, It's very old and last update was for 2008. So, maybe don't works with newer version of FFMpeg or PHP.

Solution #2 (Update 2018) (recommended)

Firstly install PHP-FFMpeg project (https://github.com/PHP-FFMpeg/PHP-FFMpeg)
(just run for install: composer require php-ffmpeg/php-ffmpeg)

And then you can use of this simple code:

<?php
require 'vendor/autoload.php';

$sec = 10;
$movie = 'test.mp4';
$thumbnail = 'thumbnail.png';

$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open($movie);
$frame = $video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds($sec));
$frame->save($thumbnail);
echo '<img src="'.$thumbnail.'">';

Description: It's newer and more modern project and works with latest version of FFMpeg and PHP. Note that it's required to proc_open() PHP function.

Late Entry.

With the advent of Java-8, we can use streams for data manipulation in a very easy/succinct way. You can use streams to sort the map entries by value and create a LinkedHashMap which preserves insertion-order iteration.

Eg:

LinkedHashMap sortedByValueMap = map.entrySet().stream()
                .sorted(comparing(Entry<Key,Value>::getValue).thenComparing(Entry::getKey))     //first sorting by Value, then sorting by Key(entries with same value)
                .collect(LinkedHashMap::new,(map,entry) -> map.put(entry.getKey(),entry.getValue()),LinkedHashMap::putAll);

For reverse ordering, replace:

comparing(Entry<Key,Value>::getValue).thenComparing(Entry::getKey)

with

comparing(Entry<Key,Value>::getValue).thenComparing(Entry::getKey).reversed()

Instead of using any 3rd party library for query operations, I would rather suggest writing queries on your own. Because using any other 3rd party packages would take away the main advantage of using dapper i.e. flexibility to write queries.

Now, there is a problem with writing Insert or Update query for the entire object. For this, one can simply create helpers like below:

InsertQueryBuilder:

 public static string InsertQueryBuilder(IEnumerable < string > fields) {


  StringBuilder columns = new StringBuilder();
  StringBuilder values = new StringBuilder();


  foreach(string columnName in fields) {
   columns.Append($ "{columnName}, ");
   values.Append($ "@{columnName}, ");

  }
  string insertQuery = $ "({ columns.ToString().TrimEnd(',', ' ')}) VALUES ({ values.ToString().TrimEnd(',', ' ')}) ";

  return insertQuery;
 }

Now, by simply passing the name of the columns to insert, the whole query will be created automatically, like below:

List < string > columns = new List < string > {
 "UserName",
 "City"
}
//QueryBuilder is the class having the InsertQueryBuilder()
string insertQueryValues = QueryBuilderUtil.InsertQueryBuilder(columns);

string insertQuery = $ "INSERT INTO UserDetails {insertQueryValues} RETURNING UserId";

Guid insertedId = await _connection.ExecuteScalarAsync < Guid > (insertQuery, userObj);

You can also modify the function to return the entire INSERT statement by passing the TableName parameter.

Make sure that the Class property names match with the field names in the database. Then only you can pass the entire obj (like userObj in our case) and values will be mapped automatically.

In the same way, you can have the helper function for UPDATE query as well:

  public static string UpdateQueryBuilder(List < string > fields) {
   StringBuilder updateQueryBuilder = new StringBuilder();

   foreach(string columnName in fields) {
    updateQueryBuilder.AppendFormat("{0}=@{0}, ", columnName);
   }
   return updateQueryBuilder.ToString().TrimEnd(',', ' ');
  }

And use it like:

List < string > columns = new List < string > {
 "UserName",
 "City"
}
//QueryBuilder is the class having the UpdateQueryBuilder()
string updateQueryValues = QueryBuilderUtil.UpdateQueryBuilder(columns);

string updateQuery =  $"UPDATE UserDetails SET {updateQueryValues} WHERE UserId=@UserId";

await _connection.ExecuteAsync(updateQuery, userObj);

Though in these helper functions also, you need to pass the name of the fields you want to insert or update but at least you have full control over the query and can also include different WHERE clauses as and when required.

Through this helper functions, you will save the following lines of code:

For Insert Query:

 $ "INSERT INTO UserDetails (UserName,City) VALUES (@UserName,@City) RETURNING UserId";

For Update Query:

$"UPDATE UserDetails SET UserName=@UserName, City=@City WHERE UserId=@UserId";

There seems to be a difference of few lines of code, but when it comes to performing insert or update operation with a table having more than 10 fields, one can feel the difference.

You can use the nameof operator to pass the field name in the function to avoid typos

Instead of:

List < string > columns = new List < string > {
 "UserName",
 "City"
}

You can write:

List < string > columns = new List < string > {
nameof(UserEntity.UserName),
nameof(UserEntity.City),
}

This will tell if you're connected to a network:

boolean connected = false;
ConnectivityManager connectivityManager = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
    if(connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).getState() == NetworkInfo.State.CONNECTED || 
            connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState() == NetworkInfo.State.CONNECTED) {
        //we are connected to a network
        connected = true;
    }
    else
        connected = false;

Warning: If you are connected to a WiFi network that doesn't include internet access or requires browser-based authentication, connected will still be true.

You will need this permission in your manifest:

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

The clue is in the name

Services and factories are similar to one another. Both will yield a singleton object that can be injected into other objects, and so are often used interchangeably.

They are intended to be used semantically to implement different design patterns.

Services are for implementing a service pattern

A service pattern is one in which your application is broken into logically consistent units of functionality. An example might be an API accessor, or a set of business logic.

This is especially important in Angular because Angular models are typically just JSON objects pulled from a server, and so we need somewhere to put our business logic.

Here is a Github service for example. It knows how to talk to Github. It knows about urls and methods. We can inject it into a controller, and it will generate and return a promise.

(function() {
  var base = "https://api.github.com";

  angular.module('github', [])
    .service('githubService', function( $http ) {
      this.getEvents: function() {
        var url = [
          base,
          '/events',
          '?callback=JSON_CALLBACK'
        ].join('');
        return $http.jsonp(url);
      }
    });
  )();

Factories implement a factory pattern

Factories, on the other hand are intended to implement a factory pattern. A factory pattern in one in which we use a factory function to generate an object. Typically we might use this for building models. Here is a factory which returns an Author constructor:

angular.module('user', [])
  .factory('User', function($resource) {
    var url = 'http://simple-api.herokuapp.com/api/v1/authors/:id'
    return $resource(url);
  })

We would make use of this like so:

angular.module('app', ['user'])
  .controller('authorController', function($scope, User) {
    $scope.user = new User();
  })

Note that factories also return singletons.

Factories can return a constructor

Because a factory simply returns an object, it can return any type of object you like, including a constructor function, as we see above.

Factories return an object; services are newable

Another technical difference is in the way services and factories are composed. A service function will be newed to generate the object. A factory function will be called and will return the object.

• Services are newable constructors.
• Factories are simply called and return an object.

This means that in a service, we append to "this" which, in the context of a constructor, will point to the object under construction.

To illustrate this, here is the same simple object created using a service and a factory:

angular.module('app', [])
  .service('helloService', function() {
    this.sayHello = function() {
      return "Hello!";
    }
  })
  .factory('helloFactory', function() {
    return {
      sayHello: function() {
        return "Hello!";
      }
    }
  });

While the other answer is correct, here's the fastest way to just go ahead and configure Meld as your visual diff tool. Just copy/paste this:

git config --global diff.tool meld
git config --global difftool.prompt false

Now run git difftool in a directory and Meld will be launched for each different file.

Side note: Meld is surprisingly slow at comparing CSV files, and no Linux diff tool I've found is faster than this Windows tool called Compare It! (last updated in 2010).

There are a number of tools specifically designed for the purpose of manipulating JSON from the command line, and will be a lot easier and more reliable than doing it with Awk, such as jq:

curl -s 'https://api.github.com/users/lambda' | jq -r '.name'

You can also do this with tools that are likely already installed on your system, like Python using the json module, and so avoid any extra dependencies, while still having the benefit of a proper JSON parser. The following assume you want to use UTF-8, which the original JSON should be encoded in and is what most modern terminals use as well:

Python 3:

curl -s 'https://api.github.com/users/lambda' | \
    python3 -c "import sys, json; print(json.load(sys.stdin)['name'])"

Python 2:

export PYTHONIOENCODING=utf8
curl -s 'https://api.github.com/users/lambda' | \
    python2 -c "import sys, json; print json.load(sys.stdin)['name']"

Frequently Asked Questions

Why not a pure shell solution?

The standard POSIX/Single Unix Specification shell is a very limited language which doesn't contain facilities for representing sequences (list or arrays) or associative arrays (also known as hash tables, maps, dicts, or objects in some other languages). This makes representing the result of parsing JSON somewhat tricky in portable shell scripts. There are somewhat hacky ways to do it, but many of them can break if keys or values contain certain special characters.

Bash 4 and later, zsh, and ksh have support for arrays and associative arrays, but these shells are not universally available (macOS stopped updating Bash at Bash 3, due to a change from GPLv2 to GPLv3, while many Linux systems don't have zsh installed out of the box). It's possible that you could write a script that would work in either Bash 4 or zsh, one of which is available on most macOS, Linux, and BSD systems these days, but it would be tough to write a shebang line that worked for such a polyglot script.

Finally, writing a full fledged JSON parser in shell would be a significant enough enough dependency that you might as well just use an existing dependency like jq or Python instead. It's not going to be a one-liner, or even small five-line snippet, to do a good implementation.

Why not use awk, sed, or grep?

It is possible to use these tools to do some quick extraction from JSON with a known shape and formatted in a known way, such as one key per line. There are several examples of suggestions for this in other answers.

However, these tools are designed for line based or record based formats; they are not designed for recursive parsing of matched delimiters with possible escape characters.

So these quick and dirty solutions using awk/sed/grep are likely to be fragile, and break if some aspect of the input format changes, such as collapsing whitespace, or adding additional levels of nesting to the JSON objects, or an escaped quote within a string. A solution that is robust enough to handle all JSON input without breaking will also be fairly large and complex, and so not too much different than adding another dependency on jq or Python.

I have had to deal with large amounts of customer data being deleted due to poor input parsing in a shell script before, so I never recommend quick and dirty methods that may be fragile in this way. If you're doing some one-off processing, see the other answers for suggestions, but I still highly recommend just using an existing tested JSON parser.

Historical notes

This answer originally recommended jsawk, which should still work, but is a little more cumbersome to use than jq, and depends on a standalone JavaScript interpreter being installed which is less common than a Python interpreter, so the above answers are probably preferable:

curl -s 'https://api.github.com/users/lambda' | jsawk -a 'return this.name'

This answer also originally used the Twitter API from the question, but that API no longer works, making it hard to copy the examples to test out, and the new Twitter API requires API keys, so I've switched to using the GitHub API which can be used easily without API keys. The first answer for the original question would be:

curl 'http://twitter.com/users/username.json' | jq -r '.text'

Full admin rights for the whole server, or a specific database? I think the others answered for a database, but for the server:

USE [master];
GO
CREATE LOGIN MyNewAdminUser 
    WITH PASSWORD    = N'abcd',
    CHECK_POLICY     = OFF,
    CHECK_EXPIRATION = OFF;
GO
EXEC sp_addsrvrolemember 
    @loginame = N'MyNewAdminUser', 
    @rolename = N'sysadmin';

You may need to leave off the CHECK_ parameters depending on what version of SQL Server Express you are using (it is almost always useful to include this information in your question).

For copy any text in Android:

            TextView text = findViewById(R.id.text_id);
            ImageView icons = findViewById(R.id.copy_icon);

            icons.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    ClipboardManager clipboardManager = (ClipboardManager)getSystemService(Context.CLIPBOARD_SERVICE);
                    ClipData clipData = ClipData.newPlainText("text whatever you want", text.getText().toString());
                    clipboardManager.setPrimaryClip(clipData);

                    Toast.makeText(context, "Text Copied", Toast.LENGTH_SHORT).show();
                }
            });

Your quotes only need to surround the value part of the attribute-equals selector, [attr='val'], like this:

$('a#check_var').click(function() {
  alert($("input:radio[name='r']:checked").val()+ ' '+
        $("input:radio[name='s']:checked").val());
});?

Swift 2.0 : Accessing Info.Plist

I have a Dictionary named CoachMarksDictionary with a boolean value in Info.Plist . I want to access the bool value and make it true.

let path = NSBundle.mainBundle().pathForResource("Info", ofType: "plist")!
  let dict = NSDictionary(contentsOfFile: path) as! [String: AnyObject]

  if let CoachMarksDict = dict["CoachMarksDictionary"] {
       print("Info.plist : \(CoachMarksDict)")

   var dashC = CoachMarksDict["DashBoardCompleted"] as! Bool
    print("DashBoardCompleted state :\(dashC) ")
  }

Writing To Plist:

From a Custom Plist:- (Make from File-New-File-Resource-PropertyList. Added three strings named : DashBoard_New, DashBoard_Draft, DashBoard_Completed)

func writeToCoachMarksPlist(status:String?,keyName:String?)
 {
  let path1 = NSBundle.mainBundle().pathForResource("CoachMarks", ofType: "plist")
  let coachMarksDICT = NSMutableDictionary(contentsOfFile: path1!)! as NSMutableDictionary
  var coachMarksMine = coachMarksDICT.objectForKey(keyName!)

  coachMarksMine  = status
  coachMarksDICT.setValue(status, forKey: keyName!)
  coachMarksDICT.writeToFile(path1!, atomically: true)
 }

The method can be called as

self.writeToCoachMarksPlist(" true - means user has checked the marks",keyName: "the key in the CoachMarks dictionary").

To make it short you could use "companion object" to get into Kotlin static world like :

  companion object {
    const val TAG = "tHomeFragment"
    fun newInstance() = HomeFragment()
}

and to make a constant field use "const val" as in the code. but try to avoid the static classes as it is making difficulties in unit testing using Mockito!.

By default CM10 only allows root access from Apps not ADB. Go to Settings -> Developer options -> Root access, and change option to "Apps and ADB".

If webview is scrollable:

1. Add this to the Manifest:

   android:hardwareAccelerated="false"
   

OR

1. Add the following to WebView in the layout:

   android:background="@android:color/transparent"
   android:layerType="software"
   

2. Add the following to the parents scroll view:

   android:layerType="software"
   

catch (Exception ex)
{
    if (!(
        ex is FormatException ||
        ex is OverflowException))
    {
        throw;
    }
    Console.WriteLine("Hello");
}

Edit:

Are you trying to do sth like this? See: http://twitter.github.com/bootstrap/javascript.html#tabs

See the working example: http://jsfiddle.net/U6aKT/

<a href="#id">go to id</a>
<div style="margin-top:2000px;"></div>
<a id="id">id</a>

assertTrue("your message", previousTokenValues[1].compareTo(currentTokenValues[1]) > 0)

this passes for previous > current values

Render is

def render(request, *args, **kwargs):
    """ Simple wrapper for render_to_response. """
    kwargs['context_instance'] = RequestContext(request)
    return render_to_response(*args, **kwargs)

So there is really no difference between render_to_response except it wraps your context making the template pre-processors work.

Direct to template is a generic view.

There is really no sense in using it here because there is overhead over render_to_response in the form of view function.

Try the following:

print "First is: %f" % (first)
print "Second is: %f" % (second)

I am unsure what answer is. But apart from that, this will be:

print "DONE: %f DIVIDED BY %f EQUALS %f, SWEET MATH BRO!" % (first, second, ans)

There's a lot of text on Format String Specifiers. You can google it and get a list of specifiers. One thing I forgot to note:

If you try this:

print "First is: %s" % (first)

It converts the float value in first to a string. So that would work as well.

You can do the following. Add your ggplot code after the first line of code and end with dev.off().

tiff("test.tiff", units="in", width=5, height=5, res=300)
# insert ggplot code
dev.off()

res=300 specifies that you need a figure with a resolution of 300 dpi. The figure file named 'test.tiff' is saved in your working directory.

Change width and height in the code above depending on the desired output.

Note that this also works for other R plots including plot, image, and pheatmap.

Other file formats

In addition to TIFF, you can easily use other image file formats including JPEG, BMP, and PNG. Some of these formats require less memory for saving.

Remember to export your routes.js.

In routes.js, write your routes and all your code in this function module:

exports = function(app, passport) {

/* write here your code */ 

}

Here is an answer proposal:

http://www.greenvilleweb.us/how-to-web-design/problem-with-ie-9-caching-ajax-get-request/

The idea is to add a parameter to your ajax query containing for example the current date an time, so the browser will not be able to cache it.

Have a look on the link, it is well explained.

If it helps you can embed a tab character in a double quoted string:

PS> "`t hello"

If you're calling "new mysqli(..)" from within a class that is namespaced, you might see a similar error Fatal error: Class 'foo\bar\mysqli' not found in. The way to fix this is to explicitly set it to the root namespace with a preceding backslash like so:

<?php 
$mysqli = new \MySQLi($db_server, $db_user, $db_pass, $db_name);

You all seem to love complication. Just click on column(to select entire column), press and hold CTRL and click on cells that you want to exclude(C1 to C5 in you case). Now you have selected entire column C (right to the end of sheet) without starting cells. All you have to do now is to rightclick and "Define Name" for your selection(ex. asdf ). In formula you use SUM(asdf). And now you're done. Good luck

Allways find the easyest way ;)

I have worked alot with msaccess vba. I think you are looking for MID function

example

    dim myReturn as string
    myreturn = mid("bonjour tout le monde",9,4)

will give you back the value "tout"

Here is what you do in Excel 2003:

1. In your sheet of interest, go to Format -> Sheet -> Hide and hide your sheet.
2. Go to Tools -> Protection -> Protect Workbook, make sure Structure is selected, and enter your password of choice.

Here is what you do in Excel 2007:

1. In your sheet of interest, go to Home ribbon -> Format -> Hide & Unhide -> Hide Sheet and hide your sheet.
2. Go to Review ribbon -> Protect Workbook, make sure Structure is selected, and enter your password of choice.

Once this is done, the sheet is hidden and cannot be unhidden without the password. Make sense?

If you really need to keep some calculations secret, try this: use Access (or another Excel workbook or some other DB of your choice) to calculate what you need calculated, and export only the "unclassified" results to your Excel workbook.

As ping works, but telnetto port 80 does not, the HTTP port 80 is closed on your machine. I assume that your browser's HTTP connection goes through a proxy (as browsing works, how else would you read stackoverflow?). You need to add some code to your python program, that handles the proxy, like described here:

Using an HTTP PROXY - Python

call/apply executes function immediately:

func.call(context, arguments);
func.apply(context, [argument1,argument2,..]);

bind doesn't execute function immediately, but returns wrapped apply function (for later execution):

function bind(func, context) {
    return function() {
        return func.apply(context, arguments);
    };
}

This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....

To cover the identities listed:

IIS_IUSRS:

This is analogous to the old IIS6 IIS_WPG group. It's a built-in group with it's security configured such that any member of this group can act as an application pool identity.

IUSR:

This account is analogous to the old IUSR_<MACHINE_NAME> local account that was the default anonymous user for IIS5 and IIS6 websites (i.e. the one configured via the Directory Security tab of a site's properties).

For more information about IIS_IUSRS and IUSR see:

Understanding Built-In User and Group Accounts in IIS 7

DefaultAppPool:

If an application pool is configured to run using the Application Pool Identity feature then a "synthesised" account called IIS AppPool\<pool name> will be created on the fly to used as the pool identity. In this case there will be a synthesised account called IIS AppPool\DefaultAppPool created for the life time of the pool. If you delete the pool then this account will no longer exist. When applying permissions to files and folders these must be added using IIS AppPool\<pool name>. You also won't see these pool accounts in your computers User Manager. See the following for more information:

Application Pool Identities

ASP.NET v4.0: -

This will be the Application Pool Identity for the ASP.NET v4.0 Application Pool. See DefaultAppPool above.

NETWORK SERVICE: -

The NETWORK SERVICE account is a built-in identity introduced on Windows 2003. NETWORK SERVICE is a low privileged account under which you can run your application pools and websites. A website running in a Windows 2003 pool can still impersonate the site's anonymous account (IUSR_ or whatever you configured as the anonymous identity).

In ASP.NET prior to Windows 2008 you could have ASP.NET execute requests under the Application Pool account (usually NETWORK SERVICE). Alternatively you could configure ASP.NET to impersonate the site's anonymous account via the <identity impersonate="true" /> setting in web.config file locally (if that setting is locked then it would need to be done by an admin in the machine.config file).

Setting <identity impersonate="true"> is common in shared hosting environments where shared application pools are used (in conjunction with partial trust settings to prevent unwinding of the impersonated account).

In IIS7.x/ASP.NET impersonation control is now configured via the Authentication configuration feature of a site. So you can configure to run as the pool identity, IUSR or a specific custom anonymous account.

LOCAL SERVICE:

The LOCAL SERVICE account is a built-in account used by the service control manager. It has a minimum set of privileges on the local computer. It has a fairly limited scope of use:

LocalService Account

LOCAL SYSTEM:

You didn't ask about this one but I'm adding for completeness. This is a local built-in account. It has fairly extensive privileges and trust. You should never configure a website or application pool to run under this identity.

LocalSystem Account

In Practice:

In practice the preferred approach to securing a website (if the site gets its own application pool - which is the default for a new site in IIS7's MMC) is to run under Application Pool Identity. This means setting the site's Identity in its Application Pool's Advanced Settings to Application Pool Identity:

In the website you should then configure the Authentication feature:

Right click and edit the Anonymous Authentication entry:

Ensure that "Application pool identity" is selected:

When you come to apply file and folder permissions you grant the Application Pool identity whatever rights are required. For example if you are granting the application pool identity for the ASP.NET v4.0 pool permissions then you can either do this via Explorer:

Click the "Check Names" button:

Or you can do this using the ICACLS.EXE utility:

icacls c:\wwwroot\mysite /grant "IIS AppPool\ASP.NET v4.0":(CI)(OI)(M)

...or...if you site's application pool is called BobsCatPicBlogthen:

icacls c:\wwwroot\mysite /grant "IIS AppPool\BobsCatPicBlog":(CI)(OI)(M)

I hope this helps clear things up.

Update:

I just bumped into this excellent answer from 2009 which contains a bunch of useful information, well worth a read:

The difference between the 'Local System' account and the 'Network Service' account?

In my case I had .Net core SDK 3.1.403 was installed. So I installed the corresponding .Net Core Windows Server Hosting which is .NET core 3.1.9 - Windows Server Hosting.

None of the other answers resize the text based off the amount of text and the size of the doughnut. Here is a small script you can use to dynamically place any amount of text in the middle, and it will automatically resize it.

Example: http://jsfiddle.net/kdvuxbtj/

It will take any amount of text in the doughnut sized perfect for the doughnut. To avoid touching the edges you can set a side-padding as a percentage of the diameter of the inside of the circle. If you don't set it, it will default to 20. You also the color, the font, and the text. The plugin takes care of the rest.

The plugin code will start with a base font size of 30px. From there it will check the width of the text and compare it against the radius of the circle and resize it based off the circle/text width ratio.

It has a default minimum font size of 20px. If the text would exceed the bounds at the minimum font size, it will wrap the text. The default line height when wrapping the text is 25px, but you can change it. If you set the default minimum font size to false, the text will become infinitely small and will not wrap.

It also has a default max font size of 75px in case there is not enough text and the lettering would be too big.

This is the plugin code

Chart.pluginService.register({
  beforeDraw: function(chart) {
    if (chart.config.options.elements.center) {
      // Get ctx from string
      var ctx = chart.chart.ctx;

      // Get options from the center object in options
      var centerConfig = chart.config.options.elements.center;
      var fontStyle = centerConfig.fontStyle || 'Arial';
      var txt = centerConfig.text;
      var color = centerConfig.color || '#000';
      var maxFontSize = centerConfig.maxFontSize || 75;
      var sidePadding = centerConfig.sidePadding || 20;
      var sidePaddingCalculated = (sidePadding / 100) * (chart.innerRadius * 2)
      // Start with a base font of 30px
      ctx.font = "30px " + fontStyle;

      // Get the width of the string and also the width of the element minus 10 to give it 5px side padding
      var stringWidth = ctx.measureText(txt).width;
      var elementWidth = (chart.innerRadius * 2) - sidePaddingCalculated;

      // Find out how much the font can grow in width.
      var widthRatio = elementWidth / stringWidth;
      var newFontSize = Math.floor(30 * widthRatio);
      var elementHeight = (chart.innerRadius * 2);

      // Pick a new font size so it will not be larger than the height of label.
      var fontSizeToUse = Math.min(newFontSize, elementHeight, maxFontSize);
      var minFontSize = centerConfig.minFontSize;
      var lineHeight = centerConfig.lineHeight || 25;
      var wrapText = false;

      if (minFontSize === undefined) {
        minFontSize = 20;
      }

      if (minFontSize && fontSizeToUse < minFontSize) {
        fontSizeToUse = minFontSize;
        wrapText = true;
      }

      // Set font settings to draw it correctly.
      ctx.textAlign = 'center';
      ctx.textBaseline = 'middle';
      var centerX = ((chart.chartArea.left + chart.chartArea.right) / 2);
      var centerY = ((chart.chartArea.top + chart.chartArea.bottom) / 2);
      ctx.font = fontSizeToUse + "px " + fontStyle;
      ctx.fillStyle = color;

      if (!wrapText) {
        ctx.fillText(txt, centerX, centerY);
        return;
      }

      var words = txt.split(' ');
      var line = '';
      var lines = [];

      // Break words up into multiple lines if necessary
      for (var n = 0; n < words.length; n++) {
        var testLine = line + words[n] + ' ';
        var metrics = ctx.measureText(testLine);
        var testWidth = metrics.width;
        if (testWidth > elementWidth && n > 0) {
          lines.push(line);
          line = words[n] + ' ';
        } else {
          line = testLine;
        }
      }

      // Move the center up depending on line height and number of lines
      centerY -= (lines.length / 2) * lineHeight;

      for (var n = 0; n < lines.length; n++) {
        ctx.fillText(lines[n], centerX, centerY);
        centerY += lineHeight;
      }
      //Draw text in center
      ctx.fillText(line, centerX, centerY);
    }
  }
});

And you use the following options in your chart object

options: {
  elements: {
    center: {
      text: 'Red is 2/3 the total numbers',
      color: '#FF6384', // Default is #000000
      fontStyle: 'Arial', // Default is Arial
      sidePadding: 20, // Default is 20 (as a percentage)
      minFontSize: 20, // Default is 20 (in px), set to false and text will not wrap.
      lineHeight: 25 // Default is 25 (in px), used for when text wraps
    }
  }
}

varchar(10) will store 10 characters, which may be more than 10 bytes. In indexes, it will allocate the maximium length of the field - so if you are using UTF8-mb4, it will allocate 40 bytes for the 10 character field.

You add your ActionListener twice to button. So correct your code for button2 to

  JButton button2 = new JButton("hello agin2");
  panel.add(button2);
  button2.addActionListener (new Action2());//note the button2 here instead of button

Furthermore, perform your Swing operations on the correct thread by using EventQueue.invokeLater

As others have mentioned before,
There is no typedef mechanism in Java.
I also do not support "fake classes" in general, but there should not be a general strict rule of thumb here:
If your code for example uses over and over and over a "generic based type" for example:

Map<String, List<Integer>> 

You should definitely consider having a subclass for that purpose.
Another approach one can consider, is for example to have in your code a deceleration like:

//@Alias Map<String, List<Integer>>  NameToNumbers;

And then use in your code NameToNumbers and have a pre compiler task (ANT/Gradle/Maven) to process and generate relevant java code.
I know that to some of the readers of this answer this might sound strange, but this is how many frameworks implemented "annotations" prior to JDK 5, this is what project lombok is doing and other frameworks.

In 5.2, you can use the request directly with:

$request->route()->getName();

or via the helper method:

request()->route()->getName();

Output example:

"home.index"

The condition i==j+1 will not be true for i==2. This can be fixed by a couple of changes to the inner loop:

#include <stdio.h>
int main(void)
{
 for (int i=2; i<100; i++)
 {
  for (int j=2; j<=i; j++)   // Changed upper bound
  {
    if (i == j)  // Changed condition and reversed order of if:s
      printf("%d\n",i);
    else if (i%j == 0)
      break;
  }
 }
}

As a general rule, you can use Database_Default collation so you don't need to figure out which one to use. However, I strongly suggest reading Simons Liew's excellent article Understanding the COLLATE DATABASE_DEFAULT clause in SQL Server

SELECT *
  FROM [FAEB].[dbo].[ExportaComisiones] AS f
  JOIN [zCredifiel].[dbo].[optPerson] AS p
  ON (p.vTreasuryId = f.RFC) COLLATE Database_Default 

I had success when using driver.close() before driver.quit(). I was previously only using driver.quit().

The difference is bucketing divides the files by Column Name, and partitioning divides the files under By a particular value inside table

Hopefully I defined it correctly

For Angular 2

<input [(ngModel)]='email' [required]='!phone' />
<input [(ngModel)]='phone' [required]='!email' /> 

You cannot use WHILE like that; see: mysql DECLARE WHILE outside stored procedure how?

You have to put your code in a stored procedure. Example:

CREATE PROCEDURE myproc()
BEGIN
    DECLARE i int DEFAULT 237692001;
    WHILE i <= 237692004 DO
        INSERT INTO mytable (code, active, total) VALUES (i, 1, 1);
        SET i = i + 1;
    END WHILE;

Alternatively, generate a list of INSERT statements using any programming language you like; for a one-time creation, it should be fine. As an example, here's a Bash one-liner:

for i in {2376921001..2376921099}; do echo "INSERT INTO mytable (code, active, total) VALUES ($i, 1, 1);"; done

By the way, you made a typo in your numbers; 2376921001 has 10 digits, 237692200 only 9.

Although my answer is not related to datatables it addresses the issue of DOM manipulation and e.g. jQuery plugin initialization for directives used on elements which have their contents updated in async manner.

Instead of implementing a timeout one could just add a watch that will listen to content changes (or even additional external triggers).

In my case I used this workaround for initializing a jQuery plugin once the ng-repeat was done which created my inner DOM - in another case I used it for just manipulating the DOM after the scope property was altered at controller. Here is how I did ...

HTML:

<div my-directive my-directive-watch="!!myContent">{{myContent}}</div>

JS:

app.directive('myDirective', [ function(){
    return {
        restrict : 'A',
        scope : {
            myDirectiveWatch : '='
        },
        compile : function(){
            return {
                post : function(scope, element, attributes){

                    scope.$watch('myDirectiveWatch', function(newVal, oldVal){
                        if (newVal !== oldVal) {
                            // Do stuff ...
                        }
                    });

                }
            }
        }
    }
}]);

Note: Instead of just casting the myContent variable to bool at my-directive-watch attribute one could imagine any arbitrary expression there.

Note: Isolating the scope like in the above example can only be done once per element - trying to do this with multiple directives on the same element will result in a $compile:multidir Error - see: https://docs.angularjs.org/error/$compile/multidir

OFFSET is nothing but a keyword to indicate starting cursor in table

SELECT column FROM table LIMIT 18 OFFSET 8 -- fetch 18 records, begin with record 9 (OFFSET 8)

you would get the same result form

SELECT column FROM table LIMIT 8, 18

visual representation (R is one record in the table in some order)

 OFFSET        LIMIT          rest of the table
 __||__   _______||_______   __||__
/      \ /                \ /
RRRRRRRR RRRRRRRRRRRRRRRRRR RRRR...
         \________________/
                 ||
             your result

Keep in mind that SQL strings can not be larger than 4000 bytes, while Pl/SQL can have strings as large as 32767 bytes. see below for an example of inserting a large string via an anonymous block which I believe will do everything you need it to do.

note I changed the varchar2(32000) to CLOB

set serveroutput ON 
CREATE TABLE testclob 
  ( 
     id NUMBER, 
     c  CLOB, 
     d  VARCHAR2(4000) 
  ); 

DECLARE 
    reallybigtextstring CLOB := '123'; 
    i                   INT; 
BEGIN 
    WHILE Length(reallybigtextstring) <= 60000 LOOP 
        reallybigtextstring := reallybigtextstring 
                               || '000000000000000000000000000000000'; 
    END LOOP; 

    INSERT INTO testclob 
                (id, 
                 c, 
                 d) 
    VALUES     (0, 
                reallybigtextstring, 
                'done'); 

    dbms_output.Put_line('I have finished inputting your clob: ' 
                         || Length(reallybigtextstring)); 
END; 

/ 
SELECT * 
FROM   testclob; 


 "I have finished inputting your clob: 60030"

If you're seeing 403 errors in your browser console, check your MVC Bundle Config. Bundle names should not match any existing folder names in your project.

eg.

bundles.Add(new StyleBundle("~/Content/css")...

...would cause issues for IIS if the folder structure $(ProjectDir)\Content\css exists in your project, since it tries to look within the existing folder for bundle content that's not there.

Instead just use something like:

bundles.Add(new StyleBundle("~/Content/cssbundle")...

I like to add this method, if you are using an edit form, you can use this code to save the changes in your update(Request $request, $id) function:

$post = Post::find($id);    
$post->fill($request->input())->save();

keep in mind that you have to name your inputs with the same column name. The fill() function will do all the work for you :)

this inside the step callback isn't the element but the object passed to animate()

$('.Count').each(function (_, self) {
    jQuery({
        Counter: 0
    }).animate({
        Counter: $(self).text()
    }, {
        duration: 1000,

        step: function () {
            $(self).text(Math.ceil(this.Counter));
        }
    });
});

Another way to do this and keep the references to this would be

$('.Count').each(function () {
    $(this).prop('Counter',0).animate({
        Counter: $(this).text()
    }, {
        duration: 1000,

        step: function (now) {
            $(this).text(Math.ceil(now));
        }
    });
});

FIDDLE

you had this

destination = Node(key: String?, neighbors: [Edge!], visited: Bool, lat: Double, long: Double)

which was place holder text above you need to insert some values

class Edge{

}

public class Node{

  var key: String?
  var neighbors: [Edge]
  var visited: Bool = false
  var lat: Double
  var long: Double

  init(key: String?, neighbors: [Edge], visited: Bool, lat: Double, long: Double) {
    self.neighbors = [Edge]()
    self.key = key
    self.visited = visited
    self.lat = lat
    self.long = long
  }

}

class Path {

  var total: Int!
  var destination: Node
  var previous: Path!

  init(){
    destination = Node(key: "", neighbors: [], visited: true, lat: 12.2, long: 22.2)
  }
}

The way for loop is processed is as follows

1 First, initialization is performed (i=0)

2 the check is performed (i < n)

3 the code in the loop is executed.

4 the value is incremented

5 Repeat steps 2 - 4

This is the reason why, there is no difference between i++ and ++i in the for loop which has been used.

If you get a python error like this:

AttributeError: 'str' object has no attribute 'some_method'

You probably poisoned your object accidentally by overwriting your object with a string.

How to reproduce this error in python with a few lines of code:

#!/usr/bin/env python
import json
def foobar(json):
    msg = json.loads(json)

foobar('{"batman": "yes"}')

Run it, which prints:

AttributeError: 'str' object has no attribute 'loads'

But change the name of the variablename, and it works fine:

#!/usr/bin/env python
import json
def foobar(jsonstring):
    msg = json.loads(jsonstring)

foobar('{"batman": "yes"}')

This error is caused when you tried to run a method within a string. String has a few methods, but not the one you are invoking. So stop trying to invoke a method which String does not define and start looking for where you poisoned your object.

The only solution that worked for me

1. Run, Type command %Temp% -> Deleting "Temporary ASP.NET Files".

Other solutions I have tried, which didn't work.

1. Cleaning/Rebuilding

2. Cleaning bin, obj folders

3. Changing namespace

This happens to me when I'm using Jinja2 for templates. The problem can be solved by running the development server using the runserver_plus command from django_extensions.

It uses the werkzeug debugger which also happens to be a lot better and has a very nice interactive debugging console. It does some ajax magic to launch a python shell at any frame (in the call stack) so you can debug.

With pure javascript:

var buttons = document.getElementsByTagName("button");
var buttonsCount = buttons.length;
for (var i = 0; i <= buttonsCount; i += 1) {
    buttons[i].onclick = function(e) {
        alert(this.id);
    };
}?

There's a lot of talks going on regarding the simplicity of asmx web services over WCF. Let me clarify few points here.

• Its true that novice web service developers will get started easily in asmx web services. Visual Studio does all the work for them and readily creates a Hello World project.
• But if you can learn WCF (which off course wont take much time) then you can get to see that WCF is also quite simple, and you can go ahead easily.
• Its important to remember that these said complexities in WCF are actually attributed to the beautiful features that it brings along with it. There are addressing, bindings, contracts and endpoints, services & clients all mentioned in the config file. The beauty is your business logic is segregated and maintained safely. Tomorrow if you need to change the binding from basicHttpBinding to netTcpBinding you can easily create a binding in config file and use it. So all the changes related to clients, communication channels, bindings etc are to be done in the configuration leaving the business logic safe & intact, which makes real good sense.
• WCF "web services" are part of a much broader spectrum of remote communication enabled through WCF. You will get a much higher degree of flexibility and portability doing things in WCF than through traditional ASMX because WCF is designed, from the ground up, to summarize all of the different distributed programming infrastructures offered by Microsoft. An endpoint in WCF can be communicated with just as easily over SOAP/XML as it can over TCP/binary and to change this medium is simply a configuration file mod. In theory, this reduces the amount of new code needed when porting or changing business needs, targets, etc.
• Web Services can be accessed only over HTTP & it works in stateless environment, where WCF is flexible because its services can be hosted in different types of applications. You can host your WCF services in Console, Windows Services, IIS & WAS, which are again different ways of creating new projects in Visual Studio.
• ASMX is older than WCF, and anything ASMX can do so can WCF (and more). Basically you can see WCF as trying to logically group together all the different ways of getting two apps to communicate in the world of Microsoft; ASMX was just one of these many ways and so is now grouped under the WCF umbrella of capabilities.
• You will always like to use Visual Studio for NET 4.0 or 4.5 as it makes life easy while creating WCF services.
• The major difference is that Web Services Use XmlSerializer. But WCF Uses DataContractSerializer which is better in Performance as compared to XmlSerializer. That's why WCF performs way better than other communication technology counterparts from .NET like asmx, .NET remoting etc.

Not to forget that I was one of those guys who liked asmx services more than WCF, but that time I was not well aware of WCF services and its capabilities. I was scared of the WCF configurations. But I dared and and tried writing few WCF services of my own, and when I learnt more of WCF, now I have no inhibitions about WCF and I recommend them to anyone & everyone. Happy coding!!!

!members.find()

I think now the best way to solve this issue is code above. It works since Groovy 1.8.1 http://docs.groovy-lang.org/docs/next/html/groovy-jdk/java/util/Collection.html#find(). Examples:

def lst1 = []
assert !lst1.find()

def lst2 = [null]
assert !lst2.find()

def lst3 = [null,2,null]
assert lst3.find()

def lst4 = [null,null,null]
assert !lst4.find()

def lst5 = [null, 0, 0.0, false, '', [], 42, 43]
assert lst5.find() == 42

def lst6 = null; 
assert !lst6.find()

You can set the value of document.location.href for this purpose. It points to the current URL. jQuery is not required to do this.

Simply grab a reference to the target view controller in prepareForSegue: method and pass any objects you need to there. Here's an example...

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    // Make sure your segue name in storyboard is the same as this line
    if ([[segue identifier] isEqualToString:@"YOUR_SEGUE_NAME_HERE"])
    {
        // Get reference to the destination view controller
        YourViewController *vc = [segue destinationViewController];

        // Pass any objects to the view controller here, like...
        [vc setMyObjectHere:object];
    }
}

REVISION: You can also use performSegueWithIdentifier:sender: method to activate the transition to a new view based on a selection or button press.

For instance, consider I had two view controllers. The first contains three buttons and the second needs to know which of those buttons has been pressed before the transition. You could wire the buttons up to an IBAction in your code which uses performSegueWithIdentifier: method, like this...

// When any of my buttons are pressed, push the next view
- (IBAction)buttonPressed:(id)sender
{
    [self performSegueWithIdentifier:@"MySegue" sender:sender];
}

// This will get called too before the view appears
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([[segue identifier] isEqualToString:@"MySegue"]) {

        // Get destination view
        SecondView *vc = [segue destinationViewController];

        // Get button tag number (or do whatever you need to do here, based on your object
        NSInteger tagIndex = [(UIButton *)sender tag];

        // Pass the information to your destination view
        [vc setSelectedButton:tagIndex];
    }
}

EDIT: The demo application I originally attached is now six years old, so I've removed it to avoid any confusion.

Each of your exec calls creates a process. You second and third calls do not run in the same shell process you create in the first one. Try putting all commands in a bat script and running it in one call: rt.exec("cmd myfile.bat"); or similar

This is a very fast way. No external libaries needed.

final protected static char[] HEXARRAY = "0123456789abcdef".toCharArray();

    public static String encodeHexString( byte[] bytes ) {

        char[] hexChars = new char[bytes.length * 2];
        for (int j = 0; j < bytes.length; j++) {
            int v = bytes[j] & 0xFF;
            hexChars[j * 2] = HEXARRAY[v >>> 4];
            hexChars[j * 2 + 1] = HEXARRAY[v & 0x0F];
        }
        return new String(hexChars);
    }

The key is to keep the declarations of the variable in the header file and source file the same.

I use this trick

------sample.c------
#define sample_c
#include sample.h

(rest of sample .c)

------sample.h------
#ifdef sample_c
#define EXTERN
#else
#define EXTERN extern
#endif

EXTERN int x;

Sample.c is only compiled once and it defines the variables. Any file that includes sample.h is only given the "extern" of the variable; it does allocate space for that variable.

When you change the type of x, it will change for everybody. You won't need to remember to change it in the source file and the header file.

Directory.GetParent(Directory.GetCurrentDirectory()).Parent.Parent.Parent.Parent.FullName

Will give you the project directory.

I do not recall my original use case for this mechanism. Nowadays, I cannot think of any valid use case.

Your client should be able to detect when the connection is lost and allow you to re-create the connection. If it important that part of program logic is executed using the same connection, then use transactions.

tl;dr; Do not use this method.

A pragmatic solution is to force MySQL to keep the connection alive:

setInterval(function () {
    db.query('SELECT 1');
}, 5000);

I prefer this solution to connection pool and handling disconnect because it does not require to structure your code in a way thats aware of connection presence. Making a query every 5 seconds ensures that the connection will remain alive and PROTOCOL_CONNECTION_LOST does not occur.

Furthermore, this method ensures that you are keeping the same connection alive, as opposed to re-connecting. This is important. Consider what would happen if your script relied on LAST_INSERT_ID() and mysql connection have been reset without you being aware about it?

However, this only ensures that connection time out (wait_timeout and interactive_timeout) does not occur. It will fail, as expected, in all others scenarios. Therefore, make sure to handle other errors.

import codecs

decode_hex = codecs.getdecoder("hex_codec")

# for an array
msgs = [decode_hex(msg)[0] for msg in msgs]

# for a string
string = decode_hex(string)[0]

Almost, we can say Python is interpreted language. But we are using some part of one time compilation process in python to convert complete source code into byte-code like java language.

You may also use LiveData that works like an EventBus.

class MyService : LifecycleService() {
    companion object {
        val BUS = MutableLiveData<Any>()
    }

    override fun onStartCommand(intent: Intent, flags: Int, startId: Int): Int {
        super.onStartCommand(intent, flags, startId)

        val testItem : Object

        // expose your data
        if (BUS.hasActiveObservers()) {
            BUS.postValue(testItem)
        }

        return START_NOT_STICKY
    }
}

Then add an observer from your Activity.

MyService.BUS.observe(this, Observer {
    it?.let {
        // Do what you need to do here
    }
})

Following are the ways

1. From the code (the way you have mentioned) ->

   displayBox.Text += sent + "\r\n";
   

   or

   displayBox.Text += sent + Environment.NewLine;
   

2. From the UI
   a) WPF

   Set TextWrapping="Wrap" and AcceptsReturn="True"   
   

   Press Enter key to the textbox and new line will be created

   b) Winform text box

   Set TextBox.MultiLine and TextBox.AcceptsReturn to true
   

Assuming it is OK that the operation is not atomic, you can do:

if (std::ifstream(name))
{
     std::cout << "File already exists" << std::endl;
     return false;
}
std::ofstream file(name);
if (!file)
{
     std::cout << "File could not be created" << std::endl;
     return false;
}
... 

Note that this doesn't work if you run multiple threads trying to create the same file, and certainly will not prevent a second process from "interfering" with the file creation because you have TOCTUI problems. [We first check if the file exists, and then create it - but someone else could have created it in between the check and the creation - if that's critical, you will need to do something else, which isn't portable].

A further problem is if you have permissions such as the file is not readable (so we can't open it for read) but is writeable, it will overwrite the file.

In MOST cases, neither of these things matter, because all you care about is telling someone that "you already have a file like that" (or something like that) in a "best effort" approach.

Here's the decoder I've been using for years...

    static const char  table[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/";
    static const int   BASE64_INPUT_SIZE = 57;

    BOOL isbase64(char c)
    {
       return c && strchr(table, c) != NULL;
    }

    inline char value(char c)
    {
       const char *p = strchr(table, c);
       if(p) {
          return p-table;
       } else {
          return 0;
       }
    }

    int UnBase64(unsigned char *dest, const unsigned char *src, int srclen)
    {
       *dest = 0;
       if(*src == 0) 
       {
          return 0;
       }
       unsigned char *p = dest;
       do
       {

          char a = value(src[0]);
          char b = value(src[1]);
          char c = value(src[2]);
          char d = value(src[3]);
          *p++ = (a << 2) | (b >> 4);
          *p++ = (b << 4) | (c >> 2);
          *p++ = (c << 6) | d;
          if(!isbase64(src[1])) 
          {
             p -= 2;
             break;
          } 
          else if(!isbase64(src[2])) 
          {
             p -= 2;
             break;
          } 
          else if(!isbase64(src[3])) 
          {
             p--;
             break;
          }
          src += 4;
          while(*src && (*src == 13 || *src == 10)) src++;
       }
       while(srclen-= 4);
       *p = 0;
       return p-dest;
    }

instead of

listItems.add("New Item");
adapter.notifyDataSetChanged();

you can directly call

adapter.add("New Item");

Use the login utility to create a login shell. Assume that the user you want to log in has the username Alice and that zsh is installed in /opt/local/bin/zsh (e.g., a more recent version installed via MacPorts). In iTerm 2, go to Preferences, Profiles, select the profile that you want to set up, and enter in Command:

login -pfq Alice /opt/local/bin/zsh

See man login for more details on the options.

inside class,

  final usernameController = TextEditingController(text: 'bhanuka');

TextField,

   child: new TextField(
        controller: usernameController,
    ...
)

Your controller should collect all the information from databases, configs, etc. There are many good reasons to stick to this. One good reason is that this will allow you to change the source of that information quite easily and not have to make any changes to your views.

It's also sometimes known as caterpillar-case

Like others have said, you need to provide the UniqueID of the control to the __doPostback() method.

__doPostBack('<%= btn.UniqueID %>', '');

On the server, the submitted form values are identified by the name attribute of the fields in the page.

The reason why UniqueID works is because UniqueID and name are in fact the same thing when the server control is rendered in HTML.

Here's an article that describes what is the UniqueID:

The UniqueID property is also used to provide value for the HTML "name" attribute of input fields (checkboxes, dropdown lists, and hidden fields). UniqueID also plays major role in postbacks. The UniqueID property of a server control, which supports postbacks, provides data for the __EVENTTARGET hidden field. The ASP.NET Runtime then uses the __EVENTTARGET field to find the control which triggered the postback and then calls its RaisePostBackEvent method.

There is an .Offset property on a Range class which allows you to do just what you need

ActiveCell.Offset(numRows, numCols)

follow up on a comment:

Dim newRange as Range
Set newRange = Range(ActiveCell, ActiveCell.Offset(numRows, numCols))

and you can verify by MsgBox newRange.Address

and here's how to assign this range to an array

If this error occurs with the jdk use this :

"c:/..../"

I had a similar problem with the SP call returning an error that an expected parameter was not included. My code was as follows.
Stored Procedure:

@Result int OUTPUT

And C#:

            SqlParameter result = cmd.Parameters.Add(new SqlParameter("@Result", DbType.Int32));
            result.Direction = ParameterDirection.ReturnValue;

In troubleshooting, I realized that the stored procedure was ACTUALLY looking for a direction of "InputOutput" so the following change fixed the problem.

            r

Result.Direction = ParameterDirection.InputOutput;

I can't get that constructor to work either. This however seems to work:

# $temp = Get-ResourceFiles
$resourceFiles = New-Object System.Collections.ArrayList($null)
$resourceFiles.AddRange($temp)

You can also pass an integer in the constructor to set an initial capacity.

What do you mean when you say you want to enumerate the files? Why can't you just filter the wanted values into a fresh array?

Edit:

It seems that you can use the array constructor like this:

$resourceFiles = New-Object System.Collections.ArrayList(,$someArray)

Note the comma. I believe what is happening is that when you call a .NET method, you always pass parameters as an array. PowerShell unpacks that array and passes it to the method as separate parameters. In this case, we don't want PowerShell to unpack the array; we want to pass the array as a single unit. Now, the comma operator creates arrays. So PowerShell unpacks the array, then we create the array again with the comma operator. I think that is what is going on.

cpython at least works on reference counting to determine when objects will be deleted. Here you have multiple references to the same objects. a refers to the same object that c[0] references. When you loop over c (for i in c:), at some point i also refers to that same object. the del keyword removes a single reference, so:

for i in c:
   del i

creates a reference to an object in c and then deletes that reference -- but the object still has other references (one stored in c for example) so it will persist.

In the same way:

def kill(self):
    del self

only deletes a reference to the object in that method. One way to remove all the references from a list is to use slice assignment:

mylist = list(range(10000))
mylist[:] = []
print(mylist)

Apparently you can also delete the slice to remove objects in place:

del mylist[:]  #This will implicitly call the `__delslice__` or `__delitem__` method.

This will remove all the references from mylist and also remove the references from anything that refers to mylist. Compared that to simply deleting the list -- e.g.

mylist = list(range(10000))
b = mylist
del mylist
#here we didn't get all the references to the objects we created ...
print(b) #[0, 1, 2, 3, 4, ...]

Finally, more recent python revisions have added a clear method which does the same thing that del mylist[:] does.

mylist = [1, 2, 3]
mylist.clear()
print(mylist)

Decided to add another answer, sorry.

We use a combination of two:

1. Honeypot field with name="email" (already mentioned by other answers) just be sure to use a sophisticated way to hide it , like moving off the screen or something. Because bots can detect display:none
2. A hidden field that is set by JavaScript when the user clicks (or focuses if you want to be TAB-friendly) on a required field (wasn't mentioned in other answers)

The 2nd option can even protect from a headless-browser type of spam (using phatnom.js or Selenium) because even JavaScript-bots don't bother actually clicking textboxes.

Blocks 99% of bots.

PS. Make sure to use the focus trick only on fields that are not being filled by password managers like LastPass or 1Passwor.

For the same reasons - mark your honeypot with autocomplete="false" tabindex="-1"

The most easy option should be to use a rounding routine:

import numpy as np
x=[9.0, 0.052999999999999999, 0.032575399999999997, 0.010892799999999999, 0.055702500000000002, 0.079330300000000006]

print('standard:')
print(x)
print("\nhuman readable:")
print(np.around(x,decimals=2))

This produces the output:

standard:
[9.0, 0.053, 0.0325754, 0.0108928, 0.0557025, 0.0793303]

human readable:
[ 9.    0.05  0.03  0.01  0.06  0.08]

Double Click the Login Button in the NETBEANS or add the Event Listener on Click Event (ActionListener)

btnLogin.addActionListener(new ActionListener() 
{
    public void actionPerformed(ActionEvent e) {
        this.setVisible(false);
        new FrmMain().setVisible(true); // Main Form to show after the Login Form..
    }
});

I think that you'll probably have to use $.ajax() if you want to change the encoding, see the contentType param below (the success and error callbacks assume you have <div id="success"></div> and <div id="error"></div> in the html):

$.ajax({
    type: "POST",
    url: "SomePage.aspx/GetSomeObjects",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    data: "{id: '" + someId + "'}",
    success: function(json) {
        $("#success").html("json.length=" + json.length);
        itemAddCallback(json);
    },
    error: function (xhr, textStatus, errorThrown) {
        $("#error").html(xhr.responseText);
    }
});

I actually just had to do this about an hour ago, what a coincidence!

instead of

mySelect.toSource()

use

mySelect.val()

Unfortunately this isn't entirely possible as the ClassLoader won't tell you what classes are available. You can, however, get fairly close doing something like this:

for (String classpathEntry : System.getProperty("java.class.path").split(System.getProperty("path.separator"))) {
    if (classpathEntry.endsWith(".jar")) {
        File jar = new File(classpathEntry);

        JarInputStream is = new JarInputStream(new FileInputStream(jar));

        JarEntry entry;
        while( (entry = is.getNextJarEntry()) != null) {
            if(entry.getName().endsWith(".class")) {
                // Class.forName(entry.getName()) and check
                //   for implementation of the interface
            }
        }
    }
}

Edit: johnstok is correct (in the comments) that this only works for standalone Java applications, and won't work under an application server.

I found this to be a little more accurate:

SELECT
   owner, table_name, TRUNC(sum(bytes)/1024/1024/1024) GB
FROM
(SELECT segment_name table_name, owner, bytes
FROM dba_segments
WHERE segment_type in  ('TABLE','TABLE PARTITION')
UNION ALL
SELECT i.table_name, i.owner, s.bytes
FROM dba_indexes i, dba_segments s
WHERE s.segment_name = i.index_name
AND   s.owner = i.owner
AND   s.segment_type in ('INDEX','INDEX PARTITION')
UNION ALL
SELECT l.table_name, l.owner, s.bytes
FROM dba_lobs l, dba_segments s
WHERE s.segment_name = l.segment_name
AND   s.owner = l.owner
AND   s.segment_type IN ('LOBSEGMENT','LOB PARTITION')
UNION ALL
SELECT l.table_name, l.owner, s.bytes
FROM dba_lobs l, dba_segments s
WHERE s.segment_name = l.index_name
AND   s.owner = l.owner
AND   s.segment_type = 'LOBINDEX')
---WHERE owner in UPPER('&owner')
GROUP BY table_name, owner
HAVING SUM(bytes)/1024/1024 > 10  /* Ignore really small tables */
ORDER BY SUM(bytes) desc

You have not placed the script tags for angular js

you can do so by using cdn or downloading the angularjs for your project and then referencing it

after this you have to add your own java script in your case main.js

that should do

You can use result.className = 'red';, but you can also use result.classList.add('red');. The .classList.add(str) way is usually easier if you need to add a class in general, and don't want to check if the class is already in the list of classes.

This seems to work, though possibly cumbersome for large lists.

>>> A = [0, 1]
>>> B = [1, 0]
>>> C = [0, 2]
>>> not sum([not i in A for i in B])
True
>>> not sum([not i in A for i in C])
False
>>> 

However, if each list must contain all the elements of other then the above code is problematic.

>>> A = [0, 1, 2]
>>> not sum([not i in A for i in B])
True

The problem arises when len(A) != len(B) and, in this example, len(A) > len(B). To avoid this, you can add one more statement.

>>> not sum([not i in A for i in B]) if len(A) == len(B) else False
False

One more thing, I benchmarked my solution with timeit.repeat, under the same conditions used by Aaron Hall in his post. As suspected, the results are disappointing. My method is the last one. set(x) == set(y) it is.

>>> def foocomprehend(): return not sum([not i in data for i in data2])
>>> min(timeit.repeat('fooset()', 'from __main__ import fooset, foocount, foocomprehend'))
25.2893661496
>>> min(timeit.repeat('foosort()', 'from __main__ import fooset, foocount, foocomprehend'))
94.3974742993
>>> min(timeit.repeat('foocomprehend()', 'from __main__ import fooset, foocount, foocomprehend'))
187.224562545

For chrome, no-cache is used to reload the page on a re-visit, but it still caches it if you go back in history (back button). To reload the page for history-back as well, use no-store. IE needs must-revalidate to work in all occasions.

So just to be sure to avoid all bugs and misinterpretations I always use

Cache-Control: no-store, no-cache, must-revalidate

if I want to make sure it reloads.

How about

1. First adding your desired result as arraylist and
2. and convert to double array as you want.

Try like this..

import java.util.ArrayList;
import java.util.List;

    public class ArrayTest {

        /**
         * @param args
         */
        public static void main(String[] args) {
            // TODO Auto-generated method stub

            // Your Prepared data. 
            List<double[]> values = new ArrayList<double[]>(2);

            double[] element1 = new double[] { 100, 100, 100, 100, 100 };
            double[] element2 = new double[] { 50, 35, 25, 45, 65 };

            values.add(element1);
            values.add(element2);

            // Add the result to arraylist.
            List<Double> temp = new ArrayList<Double>();
            for(int j=0;j<values.size(); j++) {
                for (int i = 0; i < values.get(0).length; i++) {
                    temp.add(values.get(0)[i]);
                    temp.add(values.get(1)[i]);
                }
            }

            // Convert arraylist to int[].
            Double[] result = temp.toArray(new Double[temp.size()]);
            double[] finalResult = new double[result.length]; // This hold final result.
            for (int i = 0; i < result.length; i++) {
                finalResult[i] = result[i].doubleValue();
            }

            for (int i = 0; i < finalResult.length; i++) {
                System.out.println(finalResult[i]);
            }
        }
    }

The best precision you can possibly get is through the use of the x86-only "rdtsc" instruction, which can provide clock-level resolution (ne must of course take into account the cost of the rdtsc call itself, which can be measured easily on application startup).

The main catch here is measuring the number of clocks per second, which shouldn't be too hard.

cat file2 >> file1

The >> operator appends the output to the named file or creates the named file if it does not exist.

cat file1 file2 > file3

This concatenates two or more files to one. You can have as many source files as you need. For example,

cat *.txt >> newfile.txt

Update 20130902
In the comments eumiro suggests "don't try cat file1 file2 > file1." The reason this might not result in the expected outcome is that the file receiving the redirect is prepared before the command to the left of the > is executed. In this case, first file1 is truncated to zero length and opened for output, then the cat command attempts to concatenate the now zero-length file plus the contents of file2 into file1. The result is that the original contents of file1 are lost and in its place is a copy of file2 which probably isn't what was expected.

Update 20160919
In the comments tpartee suggests linking to backing information/sources. For an authoritative reference, I direct the kind reader to the sh man page at linuxcommand.org which states:

Before a command is executed, its input and output may be redirected using a special notation interpreted by the shell.

While that does tell the reader what they need to know it is easy to miss if you aren't looking for it and parsing the statement word by word. The most important word here being 'before'. The redirection is completed (or fails) before the command is executed.

In the example case of cat file1 file2 > file1 the shell performs the redirection first so that the I/O handles are in place in the environment in which the command will be executed before it is executed.

A friendlier version in which the redirection precedence is covered at length can be found at Ian Allen's web site in the form of Linux courseware. His I/O Redirection Notes page has much to say on the topic, including the observation that redirection works even without a command. Passing this to the shell:

$ >out

...creates an empty file named out. The shell first sets up the I/O redirection, then looks for a command, finds none, and completes the operation.

unfortunately we can't use in MySQL after INSERT or UPDATE description, like in Oracle

The line (or lines) between the lines beginning <<<<<<< and ====== here:

<<<<<<< HEAD:file.txt
Hello world
=======

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

Range returns a list while xrange returns an xrange object which takes the same memory irrespective of the range size,as in this case,only one element is generated and available per iteration whereas in case of using range, all the elements are generated at once and are available in the memory.

Official Documentation for EC2-Instance works for me: https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/setting-up-node-on-ec2-instance.html

 1. curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.32.0/install.sh | bash
 2. . ~/.nvm/nvm.sh
 3. nvm ls-remote (=> find your version x.x.x =>) nvm install  x.x.x
 4. node -e "console.log('Running Node.js ' + process.version)"

Try this:

XmlDocument bodyDoc = new XmlDocument();
bodyDoc.XMLResolver = null;
bodyDoc.Load(body);

Did you try

" or \x22

instead of

\"

?

IDs are unique. Classes aren't. Elements can also have multiple classes. Also classes can be dynamically added and removed to an element.

Anywhere you can use an ID you could use a class instead. The reverse is not true.

The convention seems to be to use IDs for page elements that are on every page (like "navbar" or "menu") and classes for everything else but this is only convention and you'll find wide variance in usage.

One other difference is that for form input elements, the <label> element references a field by ID so you need to use IDs if you're going to use <label>. is an accessibility thing and you really should use it.

In years gone by IDs were also preferred because they're easily accessible in Javascript (getElementById). With the advent of jQuery and other Javascript frameworks this is pretty much a non-issue now.

There is still quirks and inconsistencies in 2019.

For example with scaled svg and pointer events, between browsers.

None of the answer of this topic are working anymore. (maybe those with jquery)

Here is an alternative, by testing with javascript if a css rule is supported, via the native CSS support api. Might evolve, to be adapted!

Note that it's possible to pass many css rules separated by a semicolon, for the finest detection.

if (CSS.supports("( -webkit-box-reflect:unset )")){
  console.log("WEBKIT BROWSER")
  // More math...
 } else {
  console.log("ENJOY")
 }

if (CSS.supports("( -moz-user-select:unset )")){
  console.log("FIREFOX!!!")
 }

Beware to not use it in loops, for performance it's better to populate a constant on load:

const ff = CSS.supports("( -moz-user-select:unset )")
if (ff){ //... } 

Using CSS only, the above would be:

@supports (-webkit-box-reflect:unset) {
  div {
    background: red
  }
}

@supports (-moz-user-select:unset) {
  div {
    background: green
  }
}

<div>
  Hello world!!
</div>

List of possible -webkit- only css rules.

List of possible -moz- only rules.

Can I use css support?

When using bluebird, you can use .bind method to share variables in promise chain:

somethingAsync().bind({})
.spread(function (aValue, bValue) {
    this.aValue = aValue;
    this.bValue = bValue;
    return somethingElseAsync(aValue, bValue);
})
.then(function (cValue) {
    return this.aValue + this.bValue + cValue;
});

please check this link for further information:

http://bluebirdjs.com/docs/api/promise.bind.html

To add to jensendp's answer:

I would pass the entity to a user created model and use the values from that entity to set the values in your newly created model. For example:

public class UserInformation {
   public string Name { get; set; }
   public int Age { get; set; }

   public UserInformation(UserEntity user) {
      this.Name = user.name;
      this.Age = user.age;
   }
}

Then change your return type to: IEnumerable<UserInformation>

You can use in this way using bootstrap css. Just remove the active class if already assinged to any row and reassign to the current row.

    $(".table tr").each(function () {
        $(this).attr("class", "");
    });
    $(this).attr("class", "active");

Try this, works fine on web-kit

.border { _x000D_
    width: 400px;_x000D_
    padding: 20px;_x000D_
    border-top: 10px solid #FFFF00;_x000D_
    border-bottom:10px solid #FF0000;_x000D_
    background-image: _x000D_
        linear-gradient(#FFFF00, #FF0000),_x000D_
        linear-gradient(#FFFF00, #FF0000)_x000D_
    ;_x000D_
    background-size:10px 100%;_x000D_
    background-position:0 0, 100% 0;_x000D_
    background-repeat:no-repeat;_x000D_
}

<div class="border">Hello!</div>

There is an alternative - you can provide a member of type XmlSerializerNamespaces in the type to be serialized. Decorate it with the XmlNamespaceDeclarations attribute. Add the namespace prefixes and URIs to that member. Then, any serialization that does not explicitly provide an XmlSerializerNamespaces will use the namespace prefix+URI pairs you have put into your type.

Example code, suppose this is your type:

[XmlRoot(Namespace = "urn:mycompany.2009")]
public class Person {
  [XmlAttribute] 
  public bool Known;
  [XmlElement]
  public string Name;
  [XmlNamespaceDeclarations]
  public XmlSerializerNamespaces xmlns;
}

You can do this:

var p = new Person
  { 
      Name = "Charley",
      Known = false, 
      xmlns = new XmlSerializerNamespaces()
  }
p.xmlns.Add("",""); // default namespace is emoty
p.xmlns.Add("c", "urn:mycompany.2009");

And that will mean that any serialization of that instance that does not specify its own set of prefix+URI pairs will use the "p" prefix for the "urn:mycompany.2009" namespace. It will also omit the xsi and xsd namespaces.

The difference here is that you are adding the XmlSerializerNamespaces to the type itself, rather than employing it explicitly on a call to XmlSerializer.Serialize(). This means that if an instance of your type is serialized by code you do not own (for example in a webservices stack), and that code does not explicitly provide a XmlSerializerNamespaces, that serializer will use the namespaces provided in the instance.

These are two different languages, that run at different time - you cannot interact with them like that.

PHP is executed on the server while the page loads. Once loaded, the JavaScript will execute on the clients machine in the browser.

You are reinventing the wheel. Normal PowerShell scripts have parameters starting with -, like script.ps1 -server http://devserver

Then you handle them in param section in the beginning of the file.

You can also assign default values to your params, read them from console if not available or stop script execution:

 param (
    [string]$server = "http://defaultserver",
    [Parameter(Mandatory=$true)][string]$username,
    [string]$password = $( Read-Host "Input password, please" )
 )

Inside the script you can simply

write-output $server

since all parameters become variables available in script scope.

In this example, the $server gets a default value if the script is called without it, script stops if you omit the -username parameter and asks for terminal input if -password is omitted.

Update: You might also want to pass a "flag" (a boolean true/false parameter) to a PowerShell script. For instance, your script may accept a "force" where the script runs in a more careful mode when force is not used.

The keyword for that is [switch] parameter type:

 param (
    [string]$server = "http://defaultserver",
    [string]$password = $( Read-Host "Input password, please" ),
    [switch]$force = $false
 )

Inside the script then you would work with it like this:

if ($force) {
  //deletes a file or does something "bad"
}

Now, when calling the script you'd set the switch/flag parameter like this:

.\yourscript.ps1 -server "http://otherserver" -force

If you explicitly want to state that the flag is not set, there is a special syntax for that

.\yourscript.ps1 -server "http://otherserver" -force:$false

Links to relevant Microsoft documentation (for PowerShell 5.0; tho versions 3.0 and 4.0 are also available at the links):

• about_Scripts
• about_Functions
• about_Functions_Advanced_Parameters

you can use inner join :

DELETE 
    ps 
FROM 
    posts ps INNER JOIN 
         (SELECT 
           distinct id 
         FROM 
             posts 
         GROUP BY id  
      HAVING COUNT(id) > 1 ) dubids on dubids.id = ps.id  

input[type=text]
{
   height: 15px; 
   line-height: 15px;
}

this is correct way to set vertical-middle position.

You can create user with no password in phpmyadmin and it solves the problem! Lebbar Abdelhadi,

If you are working with ASP.NET 3.5 and lower, and your problem is relatively simple like mine, you can just return a null row from the SQL query.

if not exists (select RepId, startdate,enddate from RepTable where RepID= 10)
     select null RepID,null StartDate,null EndDate
else
     select RepId, startdate,enddate from RepTable where RepID= 10

This solution does not require any C# code or ASP.NET code

1. Make sure you cast the null columns into appropriate names, otherwise it will not work.
2. Else block must be included which is the same query as in if not exists (query part)
3. In my case if I am using @RepID instead of 10. Which is mapped to a DropDownList box outside gridview.

Each time I change the drop down to select a different rep, Gridview is updated. If no record is found, it shows a null row.

case...when behaves a bit unexpectedly when handling classes. This is due to the fact that it uses the === operator.

That operator works as expected with literals, but not with classes:

1 === 1           # => true
Fixnum === Fixnum # => false

This means that if you want to do a case ... when over an object's class, this will not work:

obj = 'hello'
case obj.class
when String
  print('It is a string')
when Fixnum
  print('It is a number')
else
  print('It is not a string or number')
end

Will print "It is not a string or number".

Fortunately, this is easily solved. The === operator has been defined so that it returns true if you use it with a class and supply an instance of that class as the second operand:

Fixnum === 1 # => true

In short, the code above can be fixed by removing the .class:

obj = 'hello'
case obj  # was case obj.class
when String
  print('It is a string')
when Fixnum
  print('It is a number')
else
  print('It is not a string or number')
end

I hit this problem today while looking for an answer, and this was the first appearing page, so I figured it would be useful to others in my same situation.

You could use this code.

public class MySampleActivity extends Activity {
    CheckBox cb1, cb2, cb3, cb4;
    LinearLayout l1, l2, l3, l4;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        cb1 = (CheckBox) findViewById(R.id.cb1);
        cb2 = (CheckBox) findViewById(R.id.cb2);
        cb3 = (CheckBox) findViewById(R.id.cb3);
        cb4 = (CheckBox) findViewById(R.id.cb4);
        l1 = (LinearLayout) findViewById(R.id.l1);
        l2 = (LinearLayout) findViewById(R.id.l2);
        l3 = (LinearLayout) findViewById(R.id.l3);
        l4 = (LinearLayout) findViewById(R.id.l4);
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        cb1.setOnCheckedChangeListener(new MyCheckedChangeListener(1));
        cb1.setOnCheckedChangeListener(new MyCheckedChangeListener(2));
        cb1.setOnCheckedChangeListener(new MyCheckedChangeListener(3));
        cb1.setOnCheckedChangeListener(new MyCheckedChangeListener(4));
    }

    public class MyCheckedChangeListener implements CompoundButton.OnCheckedChangeListener {
        int position;

        public MyCheckedChangeListener(int position) {
            this.position = position;
        }

        private void changeVisibility(LinearLayout layout, boolean isChecked) {
            if (isChecked) {
                l1.setVisibility(View.VISIBLE);
            } else {
                l1.setVisibility(View.GONE);
            }

        }

        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            switch (position) {
                case 1:
                    changeVisibility(l1, isChecked);
                    break;
                case 2:
                    changeVisibility(l2, isChecked);
                    break;
                case 3:
                    changeVisibility(l3, isChecked);
                    break;
                case 4:
                    changeVisibility(l4, isChecked);
                    break;
            }
        }
    }
}

There's no problem with what you've done, but you must remember the difference between function declarations and function expressions.

A function declaration, that is:

function doSomething () {}

Is hoisted entirely to the top of the scope (and like let and const they are block scoped as well).

This means that the following will work:

doSomething() // works!
function doSomething() {}

A function expression, that is:

[const | let | var] = function () {} (or () =>

Is the creation of an anonymous function (function () {}) and the creation of a variable, and then the assignment of that anonymous function to that variable.

So the usual rules around variable hoisting within a scope -- block-scoped variables (let and const) do not hoist as undefined to the top of their block scope.

This means:

if (true) {
    doSomething() // will fail
    const doSomething = function () {}
}

Will fail since doSomething is not defined. (It will throw a ReferenceError)

If you switch to using var you get your hoisting of the variable, but it will be initialized to undefined so that block of code above will still not work. (This will throw a TypeError since doSomething is not a function at the time you call it)

As far as standard practices go, you should always use the proper tool for the job.

Axel Rauschmayer has a great post on scope and hoisting including es6 semantics: Variables and Scoping in ES6

This is the idiom I've always used to get a modified copy of a string without changing the original:

(my $newstring = $oldstring) =~ s/foo/bar/g;

In perl 5.14.0 or later, you can use the new /r non-destructive substitution modifier:

my $newstring = $oldstring =~ s/foo/bar/gr; 

NOTE:
The above solutions work without g too. They also work with any other modifiers.

If you are using Symfony 2.7 or above, and don't want to include any additional bundle for serializing, maybe you can follow this way to seialize doctrine entities to json -

1. In my (common, parent) controller, I have a function that prepares the serializer

   use Symfony\Component\Serializer\Encoder\JsonEncoder;
   use Symfony\Component\Serializer\Mapping\Factory\ClassMetadataFactory;
   use Symfony\Component\Serializer\Mapping\Loader\AnnotationLoader;
   use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;
   use Symfony\Component\Serializer\Serializer;
   
   // -----------------------------
   
   /**
    * @return Serializer
    */
   protected function _getSerializer()
   {  
       $classMetadataFactory = new ClassMetadataFactory(new AnnotationLoader(new AnnotationReader()));
       $normalizer           = new ObjectNormalizer($classMetadataFactory);
   
       return new Serializer([$normalizer], [new JsonEncoder()]);
   }
   

2. Then use it to serialize Entities to JSON

   $this->_getSerializer()->normalize($anEntity, 'json');
   $this->_getSerializer()->normalize($arrayOfEntities, 'json');
   

Done!

But you may need some fine tuning. For example -

• If your entities have circular reference, check how to handle it.
• If you want to ignore some properties, can do it
• Even better, you can serialize only selective attributes.

For clarity, the formulas that use a square root need to be

sqrt(coefficient * (colour_value^2))

not

sqrt((coefficient * colour_value))^2

The proof of this lies in the conversion of a R=G=B triad to greyscale R. That will only be true if you square the colour value, not the colour value times coefficient. See Nine Shades of Greyscale

You might want to use python's rpy2 module. However, the "right" way to do this is with R CMD BATCH. You can modify this to write to STDOUT, but the default is to write to a .Rout file. See example below:

[ramanujan:~]$cat foo.R
print(rnorm(10))
[ramanujan:~]$R CMD BATCH foo.R
[ramanujan:~]$cat foo.Rout

I know it's an old post, already answered, but I found another solution without adding css classes or doing too much javascript than really needed, and I want to share it, hoping can help someone.

I found that to enable :hover effect on every kind of elements on a Touch enabled browser, you need to tell him that your elements are clickable. To do so you can simply add an empty handler to the click function with jQuery or javascript.

$('.need-hover').on('click', function(){ });

It's better if you do so only on Mobile enabled browsers with this snippet:

// check for css :hover supports and save in a variable
var supportsTouch = (typeof Touch == "object");

if(supportsTouch){ 
    // not supports :hover
    $('.need-hover').on('click', function(){ });
}

Use pd.concat to merge a list of DataFrame into a single big DataFrame.

appended_data = []
for infile in glob.glob("*.xlsx"):
    data = pandas.read_excel(infile)
    # store DataFrame in list
    appended_data.append(data)
# see pd.concat documentation for more info
appended_data = pd.concat(appended_data)
# write DataFrame to an excel sheet 
appended_data.to_excel('appended.xlsx')

Edit: now there is yet an easier way to do this - when creating your group, just mention the full bot name (eg. @UniversalAgent1Bot) and it will list it as you type. Then you can just tap on it to add it.

Old answer:

1. Create a new group from the menu. Don't add any bots yet
2. Find the bot (for instance you can go to Contacts and search for it)
3. Tap to open
4. Tap the bot name on the top bar. Your page becomes like this:
5. Now, tap the triple ... and you will get the Add to Group button:
6. Now select your group and add the bot - and confirm the addition

This question was asked in 2012 before flexbox. The correct way to solve this problem using modern CSS is with a media query and a flex column reversal for mobile devices. No absolute positioning is needed.

https://jsfiddle.net/tnhsaesop/vjftq198/3/

HTML:

<div class="parent">
  <div style="background-color:lightgrey;">
    <p>
      I stay on top on desktop and I'm on bottom on mobile
    </p>
  </div>
  <div style="background-color:grey;">
    <p>
      I stay on bottom on desktop and I'm on top on mobile
    </p>
  </div>
</div>

CSS:

.parent {
  display: flex;
  flex-direction: column;
}

@media (max-width: 768px) {
  .parent {
    flex-direction: column-reverse;
  }
}

numba

For recursive calculations which are not vectorisable, numba, which uses JIT-compilation and works with lower level objects, often yields large performance improvements. You need only define a regular for loop and use the decorator @njit or (for older versions) @jit(nopython=True):

For a reasonable size dataframe, this gives a ~30x performance improvement versus a regular for loop:

from numba import jit

@jit(nopython=True)
def calculator_nb(a, b, d):
    res = np.empty(d.shape)
    res[0] = d[0]
    for i in range(1, res.shape[0]):
        res[i] = res[i-1] * a[i] + b[i]
    return res

df['C'] = calculator_nb(*df[list('ABD')].values.T)

n = 10**5
df = pd.concat([df]*n, ignore_index=True)

# benchmarking on Python 3.6.0, Pandas 0.19.2, NumPy 1.11.3, Numba 0.30.1
# calculator() is same as calculator_nb() but without @jit decorator
%timeit calculator_nb(*df[list('ABD')].values.T)  # 14.1 ms per loop
%timeit calculator(*df[list('ABD')].values.T)     # 444 ms per loop

To check if a specific package is installed:

conda list html5lib

which outputs something like this if installed:

# packages in environment at C:\ProgramData\Anaconda3:
#
# Name                    Version                   Build  Channel
html5lib                  1.0.1                    py37_0

or something like this if not installed:

# packages in environment at C:\ProgramData\Anaconda3:
#
# Name                    Version                   Build  Channel

you don't need to type the exact package name. Partial matches are supported:

conda list html

This outputs all installed packages containing 'html':

# packages in environment at C:\ProgramData\Anaconda3:
#
# Name                    Version                   Build  Channel

Something I found later which helped, is the .ReadWriteTimeout property. This, in addition to the .Timeout property seemed to finally cut down on the time threads would spend trying to download from a problematic server. The default time for .ReadWriteTimeout is 5 minutes, which for my application was far too long.

So, it seems to me:

.Timeout = time spent trying to establish a connection (not including lookup time) .ReadWriteTimeout = time spent trying to read or write data after connection established

More info: HttpWebRequest.ReadWriteTimeout Property

Edit:

Per @KyleM's comment, the Timeout property is for the entire connection attempt, and reading up on it at MSDN shows:

Timeout is the number of milliseconds that a subsequent synchronous request made with the GetResponse method waits for a response, and the GetRequestStream method waits for a stream. The Timeout applies to the entire request and response, not individually to the GetRequestStream and GetResponse method calls. If the resource is not returned within the time-out period, the request throws a WebException with the Status property set to WebExceptionStatus.Timeout.

(Emphasis mine.)

You need Linq - System.Xml.Linq to be precise.

You can create XML using XElement from scratch - that should pretty much sort you out.

Frankly, sometimes we need to obfuscate the code (for example, register license classes and so on). In this case, your project is not free. IMO, you should pay for a good obfucator.

Dotfuscator hides your code and .NET Reflector shows an error when you attempt to decompile it.

I used dir /s /b /o:n /a:d, and it worked perfectly, just make sure you let the file finish writing, or you'll have an incomplete list.

Most likely, as mentioned by others, it is a class carrying the css values:

.clear{clear: both;} 

in order to prevent any more page elements from extending into the footer element. It is a quick and easy way of making sure that pages with columns of varying heights don't cause the footer to render oddly, by possibly setting its top position at the end of a shorter column.

In many cases it is not necessary, but if you are using best-practice standards it is a good idea to use, if you are floating page elements left and right. It functions with page elements similar to the way a horizontal rule works with text, to ensure proper and complete sepperation.

Update (2020)

Google has added a new ActivityResultRegistry API that "lets you handle the startActivityForResult() + onActivityResult() as well as requestPermissions() + onRequestPermissionsResult() flows without overriding methods in your Activity or Fragment, brings increased type safety via ActivityResultContract, and provides hooks for testing these flows" - source.

The API was added in androidx.activity 1.2.0-alpha02 and androidx.fragment 1.3.0-alpha02.

So you are now able to do something like:

val takePicture = registerForActivityResult(ActivityResultContracts.TakePicture()) { success: Boolean ->
    if (success) {
        // The image was saved into the given Uri -> do something with it
    }
}

val imageUri: Uri = ...
button.setOnClickListener {
    takePicture.launch(imageUri)
}

Take a look at the documentation to learn how to use the new Activity result API: https://developer.android.com/training/basics/intents/result#kotlin

There are many built-in ActivityResultContracts that allow you to do different things like pick contacts, request permissions, take pictures or take videos. You are probably interested in the ActivityResultContracts.TakePicture shown above.

Note that androidx.fragment 1.3.0-alpha04 deprecates the startActivityForResult() + onActivityResult() and requestPermissions() + onRequestPermissionsResult() APIs on Fragment. Hence it seems that ActivityResultContracts is the new way to do things from now on.

Original answer (2015)

It took me some hours to get this working. The code it's almost a copy-paste from developer.android.com, with a minor difference.

Request this permission on the AndroidManifest.xml:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

On your Activity, start by defining this:

static final int REQUEST_IMAGE_CAPTURE = 1;
private Bitmap mImageBitmap;
private String mCurrentPhotoPath;
private ImageView mImageView;

Then fire this Intent in an onClick:

Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (cameraIntent.resolveActivity(getPackageManager()) != null) {
    // Create the File where the photo should go
    File photoFile = null;
    try {
        photoFile = createImageFile();
    } catch (IOException ex) {
        // Error occurred while creating the File
        Log.i(TAG, "IOException");
    }
    // Continue only if the File was successfully created
    if (photoFile != null) {
        cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
        startActivityForResult(cameraIntent, REQUEST_IMAGE_CAPTURE);
    }
}

Add the following support method:

private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
            imageFileName,  // prefix
            ".jpg",         // suffix
            storageDir      // directory
    );

    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = "file:" + image.getAbsolutePath();
    return image;
}

Then receive the result:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
        try {
            mImageBitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(mCurrentPhotoPath));
            mImageView.setImageBitmap(mImageBitmap);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

What made it work is the MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(mCurrentPhotoPath)), which is different from the code from developer.android.com. The original code gave me a FileNotFoundException.

Whitespace includes space, tabs and CRLF. So an elegant and one-liner string function we can use is translate.

' hello apple'.translate(None, ' \n\t\r')

OR if you want to be thorough

import string
' hello  apple'.translate(None, string.whitespace)

Just simply 'export' variable and 'import' in your class

export var GOOGLE_API_URL = 'https://www.googleapis.com/admin/directory/v1';

// default err string message
export var errStringMsg = 'Something went wrong';

Now use it as,

import appConstants = require('../core/AppSettings');
console.log(appConstants.errStringMsg);
console.log(appConstants.GOOGLE_API_URL);

You should try something like $_SERVER['HTTP_REFERER'].

If you can get away with it, static const has a lot of advantages. It obeys the normal scope principles, is visible in a debugger, and generally obeys the rules that variables obey.

However, at least in the original C standard, it isn't actually a constant. If you use #define var 5, you can write int foo[var]; as a declaration, but you can't do that (except as a compiler extension" with static const int var = 5;. This is not the case in C++, where the static const version can be used anywhere the #define version can, and I believe this is also the case with C99.

However, never name a #define constant with a lowercase name. It will override any possible use of that name until the end of the translation unit. Macro constants should be in what is effectively their own namespace, which is traditionally all capital letters, perhaps with a prefix.

I had the same issue. I used the following steps to make it work

sudo pip uninstall virtualenv

sudo -H pip install virtualenv

That is it. It started working.

Usage of sudo -H----> sudo -H: set HOME variable to target user's home dir.

This should work as well:

DELETE FROM [table] 
INNER JOIN (
    SELECT [id] 
    FROM (
        SELECT [id] 
        FROM [table] 
        ORDER BY [id] DESC
        LIMIT N
    ) AS Temp
) AS Temp2 ON [table].[id] = [Temp2].[id]

The issue is with

• how ES6 modules are emulated in CommonJS
• how you import the module

ES6 to CommonJS

At the time of writing this, no environment supports ES6 modules natively. When using them in Node.js you need to use something like Babel to convert the modules to CommonJS. But how exactly does that happen?

Many people consider module.exports = ... to be equivalent to export default ... and exports.foo ... to be equivalent to export const foo = .... That's not quite true though, or at least not how Babel does it.

ES6 default exports are actually also named exports, except that default is a "reserved" name and there is special syntax support for it. Lets have a look how Babel compiles named and default exports:

// input
export const foo = 42;
export default 21;

// output
"use strict";

Object.defineProperty(exports, "__esModule", {
  value: true
});
var foo = exports.foo = 42;
exports.default = 21; 

Here we can see that the default export becomes a property on the exports object, just like foo.

Import the module

We can import the module in two ways: Either using CommonJS or using ES6 import syntax.

Your issue: I believe you are doing something like:

var bar = require('./input');
new bar();

expecting that bar is assigned the value of the default export. But as we can see in the example above, the default export is assigned to the default property!

So in order to access the default export we actually have to do

var bar = require('./input').default;

If we use ES6 module syntax, namely

import bar from './input';
console.log(bar);

Babel will transform it to

'use strict';

var _input = require('./input');

var _input2 = _interopRequireDefault(_input);

function _interopRequireDefault(obj) { return obj && obj.__esModule ? obj : { default: obj }; }

console.log(_input2.default);

You can see that every access to bar is converted to access .default.

My way of exporting/importing image assets. I use Sketch design.

Step 1. Sketch: export using Android preset

Step 2. Finder: Go to the export folder > Cmd+C

Step 3. Finder: Go to your project's /res folder > Cmd+V > Apply to all > Merge

OK, the images are in your project now.

I didn’t see any mention in the existing answers of issues related to astral plane code points or internationalization. “Uppercase” doesn’t mean the same thing in every language using a given script.

Initially I didn’t see any answers addressing issues related to astral plane code points. There is one, but it’s a bit buried (like this one will be, I guess!)

Most of the proposed functions look like this:

function capitalizeFirstLetter(str) {
  return str[0].toUpperCase() + str.slice(1);
}

However, some cased characters fall outside the BMP (basic multilingual plane, code points U+0 to U+FFFF). For example take this Deseret text:

capitalizeFirstLetter(""); // ""

The first character here fails to capitalize because the array-indexed properties of strings don’t access “characters” or code points*. They access UTF-16 code units. This is true also when slicing — the index values point at code units.

It happens to be that UTF-16 code units are 1:1 with USV code points within two ranges, U+0 to U+D7FF and U+E000 to U+FFFF inclusive. Most cased characters fall into those two ranges, but not all of them.

From ES2015 on, dealing with this became a bit easier. String.prototype[@@iterator] yields strings corresponding to code points**. So for example, we can do this:

function capitalizeFirstLetter([ first, ...rest ]) {
  return [ first.toUpperCase(), ...rest ].join('');
}

capitalizeFirstLetter("") // ""

For longer strings, this is probably not terribly efficient*** — we don’t really need to iterate the remainder. We could use String.prototype.codePointAt to get at that first (possible) letter, but we’d still need to determine where the slice should begin. One way to avoid iterating the remainder would be to test whether the first codepoint is outside the BMP; if it isn’t, the slice begins at 1, and if it is, the slice begins at 2.

function capitalizeFirstLetter(str) {
  const firstCP = str.codePointAt(0);
  const index = firstCP > 0xFFFF ? 2 : 1;

  return String.fromCodePoint(firstCP).toUpperCase() + str.slice(index);
}

capitalizeFirstLetter("") // ""

You could use bitwise math instead of > 0xFFFF there, but it’s probably easier to understand this way and either would achieve the same thing.

We can also make this work in ES5 and below by taking that logic a bit further if necessary. There are no intrinsic methods in ES5 for working with codepoints, so we have to manually test whether the first code unit is a surrogate****:

function capitalizeFirstLetter(str) {
  var firstCodeUnit = str[0];

  if (firstCodeUnit < '\uD800' || firstCodeUnit > '\uDFFF') {
    return str[0].toUpperCase() + str.slice(1);
  }

  return str.slice(0, 2).toUpperCase() + str.slice(2);
}

capitalizeFirstLetter("") // ""

At the start I also mentioned internationalization considerations. Some of these are very difficult to account for because they require knowledge not only of what language is being used, but also may require specific knowledge of the words in the language. For example, the Irish digraph "mb" capitalizes as "mB" at the start of a word. Another example, the German eszett, never begins a word (afaik), but still helps illustrate the problem. The lowercase eszett (“ß”) capitalizes to “SS,” but “SS” could lowercase to either “ß” or “ss” — you require out-of-band knowledge of the German language to know which is correct!

The most famous example of these kinds of issues, probably, is Turkish. In Turkish Latin, the capital form of i is I, while the lowercase form of I is i — they’re two different letters. Fortunately we do have a way to account for this:

function capitalizeFirstLetter([ first, ...rest ], locale) {
  return [ first.toLocaleUpperCase(locale), ...rest ].join('');
}

capitalizeFirstLetter("italy", "en") // "Italy"
capitalizeFirstLetter("italya", "tr") // "Italya"

In a browser, the user’s most-preferred language tag is indicated by navigator.language, a list in order of preference is found at navigator.languages, and a given DOM element’s language can be obtained (usually) with Object(element.closest('[lang]')).lang || YOUR_DEFAULT_HERE in multilanguage documents.

In agents which support Unicode property character classes in RegExp, which were introduced in ES2018, we can clean stuff up further by directly expressing what characters we’re interested in:

function capitalizeFirstLetter(str, locale=navigator.language) {
  return str.replace(/^\p{CWU}/u, char => char.toLocaleUpperCase(locale));
}

This could be tweaked a bit to also handle capitalizing multiple words in a string with fairly good accuracy. The CWU or Changes_When_Uppercased character property matches all code points which, well, change when uppercased. We can try this out with a titlecased digraph characters like the Dutch ? for example:

capitalizeFirstLetter('?sselmeer'); // "?sselmeer"

As of January 2021, all major engines have implemented the Unicode property character class feature, but depending on your target support range you may not be able to use it safely yet. The last browser to introduce support was Firefox (78; June 30, 2020). You can check for support of this feature with the Kangax compat table. Babel can be used to compile RegExp literals with property references to equivalent patterns without them, but be aware that the resulting code can sometimes be enormous. You probably would not want to do this unless you’re certain the tradeoff is justified for your use case.

In all likelihood, people asking this question will not be concerned with Deseret capitalization or internationalization. But it’s good to be aware of these issues because there’s a good chance you’ll encounter them eventually even if they aren’t concerns presently. They’re not “edge” cases, or rather, they’re not by-definition edge cases — there’s a whole country where most people speak Turkish, anyway, and conflating code units with codepoints is a fairly common source of bugs (especially with regard to emoji). Both strings and language are pretty complicated!

* The code units of UTF-16 / UCS2 are also Unicode code points in the sense that e.g. U+D800 is technically a code point, but that’s not what it “means” here ... sort of ... though it gets pretty fuzzy. What the surrogates definitely are not, though, is USVs (Unicode scalar values).

** Though if a surrogate code unit is “orphaned” — i.e., not part of a logical pair — you could still get surrogates here, too.

*** maybe. I haven’t tested it. Unless you have determined capitalization is a meaningful bottleneck, I probably wouldn’t sweat it — choose whatever you believe is most clear and readable.

**** such a function might wish to test both the first and second code units instead of just the first, since it’s possible that the first unit is an orphaned surrogate. For example the input "\uD800x" would capitalize the X as-is, which may or may not be expected.

Attention: this is an extremely rough and oversimplified sketch, assuming the simplest possible HTTP request (no HTTPS, no HTTP2, no extras), simplest possible DNS, no proxies, single-stack IPv4, one HTTP request only, a simple HTTP server on the other end, and no problems in any step. This is, for most contemporary intents and purposes, an unrealistic scenario; all of these are far more complex in actual use, and the tech stack has become an order of magnitude more complicated since this was written. With this in mind, the following timeline is still somewhat valid:

1. browser checks cache; if requested object is in cache and is fresh, skip to #9
2. browser asks OS for server's IP address
3. OS makes a DNS lookup and replies the IP address to the browser
4. browser opens a TCP connection to server (this step is much more complex with HTTPS)
5. browser sends the HTTP request through TCP connection
6. browser receives HTTP response and may close the TCP connection, or reuse it for another request
7. browser checks if the response is a redirect or a conditional response (3xx result status codes), authorization request (401), error (4xx and 5xx), etc.; these are handled differently from normal responses (2xx)
8. if cacheable, response is stored in cache
9. browser decodes response (e.g. if it's gzipped)
10. browser determines what to do with response (e.g. is it a HTML page, is it an image, is it a sound clip?)
11. browser renders response, or offers a download dialog for unrecognized types

Again, discussion of each of these points have filled countless pages; take this only as a summary, abridged for the sake of clarity. Also, there are many other things happening in parallel to this (processing typed-in address, speculative prefetching, adding page to browser history, displaying progress to user, notifying plugins and extensions, rendering the page while it's downloading, pipelining, connection tracking for keep-alive, cookie management, checking for malicious content etc.) - and the whole operation gets an order of magnitude more complex with HTTPS (certificates and ciphers and pinning, oh my!).

One thing to keep in mind is that the relevant path here is the path relative to the file system location of your class... in your case TestGameTable.class. It is not related to the location of the TestGameTable.java file.
I left a more detailed answer here... where is resource actually located

You may declare a value in color.xml, and thus you can get integer value by calling the code below.

context.getColor(int resId);

If you have Perl 5.14 or greater, you can use the /r option with the substitution operator to perform non-destructive substitution:

print "bla: ", $myvar =~ s/a/b/r, "\n";

In earlier versions you can achieve the same using a do() block with a temporary lexical variable, e.g.:

print "bla: ", do { (my $tmp = $myvar) =~ s/a/b/; $tmp }, "\n";

So, pretty much here is your problem. The close button on the upper right of a window frame is not part of the WPF window, but it belongs to the part of the window frame that is controled by your OS. This means you will have to use Win32 interop to do it.

alternativly, you can use the noframe and either provide your own "frame" or have no frame at all.

It's very useful for beginners to know why join is a string method.

It's very strange at the beginning, but very useful after this.

The result of join is always a string, but the object to be joined can be of many types (generators, list, tuples, etc).

.join is faster because it allocates memory only once. Better than classical concatenation (see, extended explanation).

Once you learn it, it's very comfortable and you can do tricks like this to add parentheses.

>>> ",".join("12345").join(("(",")"))
Out:
'(1,2,3,4,5)'

>>> list = ["(",")"]
>>> ",".join("12345").join(list)
Out:
'(1,2,3,4,5)'

You need to add query.addEntity(SwitcherServiceSource.class) before calling the .list() on query.

I have edited the function for you,

void readFile()
{
    ifstream file;
    file.open ("program.txt");
    if (!file.is_open()) return;

    string word;
    while (file >> word)
    {
        cout<< word << '\n';
    }
}

You can click on the Project window, press Alt-Insert, and select Folder->Assets Folder. Android Studio will add it automatically to the correct location.

You are most likely looking at your Project with the new(ish) "Android View". Note that this is a view and not the actual folder structure on disk (which hasn't changed since the introduction of Gradle as the new build tool). You can switch to the old "Project View" by clicking on the word "Android" at the top of the Project window and selecting "Project".

if rate is the sampling rate(Hz), then np.linspace(0, rate/2, n) is the frequency array of every point in fft. You can use rfft to calculate the fft in your data is real values:

import numpy as np
import pylab as pl
rate = 30.0
t = np.arange(0, 10, 1/rate)
x = np.sin(2*np.pi*4*t) + np.sin(2*np.pi*7*t) + np.random.randn(len(t))*0.2
p = 20*np.log10(np.abs(np.fft.rfft(x)))
f = np.linspace(0, rate/2, len(p))
plot(f, p)

signal x contains 4Hz & 7Hz sin wave, so there are two peaks at 4Hz & 7Hz.

I think the proper way to use **kwargs in Python when it comes to default values is to use the dictionary method setdefault, as given below:

class ExampleClass:
    def __init__(self, **kwargs):
        kwargs.setdefault('val', value1)
        kwargs.setdefault('val2', value2)

In this way, if a user passes 'val' or 'val2' in the keyword args, they will be used; otherwise, the default values that have been set will be used.

Database tables

To demonstrate how the USING and ON clauses work, let's assume we have the following post and post_comment database tables, which form a one-to-many table relationship via the post_id Foreign Key column in the post_comment table referencing the post_id Primary Key column in the post table:

The parent post table has 3 rows:

| post_id | title     |
|---------|-----------|
| 1       | Java      |
| 2       | Hibernate |
| 3       | JPA       |

and the post_comment child table has the 3 records:

| post_comment_id | review    | post_id |
|-----------------|-----------|---------|
| 1               | Good      | 1       |
| 2               | Excellent | 1       |
| 3               | Awesome   | 2       |

The JOIN ON clause using a custom projection

Traditionally, when writing an INNER JOIN or LEFT JOIN query, we happen to use the ON clause to define the join condition.

For example, to get the comments along with their associated post title and identifier, we can use the following SQL projection query:

SELECT
   post.post_id,
   title,
   review
FROM post
INNER JOIN post_comment ON post.post_id = post_comment.post_id
ORDER BY post.post_id, post_comment_id

And, we get back the following result set:

| post_id | title     | review    |
|---------|-----------|-----------|
| 1       | Java      | Good      |
| 1       | Java      | Excellent |
| 2       | Hibernate | Awesome   |

The JOIN USING clause using a custom projection

When the Foreign Key column and the column it references have the same name, we can use the USING clause, like in the following example:

SELECT
  post_id,
  title,
  review
FROM post
INNER JOIN post_comment USING(post_id)
ORDER BY post_id, post_comment_id

And, the result set for this particular query is identical to the previous SQL query that used the ON clause:

| post_id | title     | review    |
|---------|-----------|-----------|
| 1       | Java      | Good      |
| 1       | Java      | Excellent |
| 2       | Hibernate | Awesome   |

The USING clause works for Oracle, PostgreSQL, MySQL, and MariaDB. SQL Server doesn't support the USING clause, so you need to use the ON clause instead.

The USING clause can be used with INNER, LEFT, RIGHT, and FULL JOIN statements.

SQL JOIN ON clause with SELECT *

Now, if we change the previous ON clause query to select all columns using SELECT *:

SELECT *
FROM post
INNER JOIN post_comment ON post.post_id = post_comment.post_id
ORDER BY post.post_id, post_comment_id

We are going to get the following result set:

| post_id | title     | post_comment_id | review    | post_id |
|---------|-----------|-----------------|-----------|---------|
| 1       | Java      | 1               | Good      | 1       |
| 1       | Java      | 2               | Excellent | 1       |
| 2       | Hibernate | 3               | Awesome   | 2       |

As you can see, the post_id is duplicated because both the post and post_comment tables contain a post_id column.

SQL JOIN USING clause with SELECT *

On the other hand, if we run a SELECT * query that features the USING clause for the JOIN condition:

SELECT *
FROM post
INNER JOIN post_comment USING(post_id)
ORDER BY post_id, post_comment_id

We will get the following result set:

| post_id | title     | post_comment_id | review    |
|---------|-----------|-----------------|-----------|
| 1       | Java      | 1               | Good      |
| 1       | Java      | 2               | Excellent |
| 2       | Hibernate | 3               | Awesome   |

You can see that this time, the post_id column is deduplicated, so there is a single post_id column being included in the result set.

Conclusion

If the database schema is designed so that Foreign Key column names match the columns they reference, and the JOIN conditions only check if the Foreign Key column value is equal to the value of its mirroring column in the other table, then you can employ the USING clause.

Otherwise, if the Foreign Key column name differs from the referencing column or you want to include a more complex join condition, then you should use the ON clause instead.

var arr = [];             //new storage
str = str.split(' ');     //split by spaces
arr.push(str.shift());    //add the number
arr.push(str.join(' '));  //and the rest of the string

//arr is now:
["72","tocirah sneab"];

but i still think there is a faster way though.

Renders a view and sends the rendered HTML string to the client.

res.render('index');

Or

res.render('index', function(err, html) {
  if(err) {...}
  res.send(html);
});

In HTML5, there is no correct value, all the major browsers do not really care what the attribute is, they are just checking if the attribute exists so the element is disabled.
