You are pointing your JAVA_HOME to the JRE which is the Java Runtime Environment. The runtime environment doesn't have a java compiler in its bin folder. You should download the JDK which is the Java Development Kit. Once you've installed that, you can see in your bin folder that there's a file called javac.exe. That's your compiler.

Close the terminal(End the current session). Open it again.

Not in stock Windows but it is provided by Services for Unix and there are several simple batch scripts floating around that accomplish the same thing such this this one.

df['col'] = 'str' + df['col'].astype(str)

Example:

>>> df = pd.DataFrame({'col':['a',0]})
>>> df
  col
0   a
1   0
>>> df['col'] = 'str' + df['col'].astype(str)
>>> df
    col
0  stra
1  str0

A little bit off topic maybe, but for modern browsers (IE9 and newer) you can use the css odd/even selectors to achieve want you want.

tr:nth-child(even) { /* your alt-row stuff */}
tr:nth-child(odd) { /* the other rows */ }

or

tr { /* all table rows */ }
tr:nth-child(even) { /* your alt-row stuff */}

Try this:

private void btnAtt_Click(object sender, EventArgs e) {

    openFileDialog1.ShowDialog();
    Attachment myFile = new Attachment(openFileDialog1.FileName);

    MyMsg.Attachments.Add(myFile);


}

Another way of achieving the same result is to use the @Value annotation:

public class Main {
     private Country country;

     @Autowired
     public void setCountry(@Value("#{country}") Country country) {
          this.country = country;
     }
}

In this case, the "#{country} string is an Spring Expression Language (SpEL) expression which evaluates to a bean named country.

The easiest way is to do:

chmod -R u+rwX,go+rX,go-w /path/to/dir

which basically means:

to change file modes -Recursively by giving:

• user: read, write and eXecute permissions,
• group and other users: read and eXecute permissions, but not -write permission.

Please note that X will make a directory executable, but not a file, unless it's already searchable/executable.

+X - make a directory or file searchable/executable by everyone if it is already searchable/executable by anyone.

Please check man chmod for more details.

Tabbing through controls usually happens sequentially as they appear on the HTML code.

Using tabindex, the tabbing will flow from control with the lowest tabindex to the control with the highest tabindex in tabindex sequential order

you simple type:

timestamps.sort()
timestamps=timestamps[::-1]

A nice read about the problem and its possible solutions can be found in this blog post: Addressing the iOS Address Bar in 100vh Layouts

The solution I ended up in my React application is utilising the react-div-100vh library described in the post above.

See Request.setRetryPolicy() and the constructor for DefaultRetryPolicy, e.g.

JsonObjectRequest myRequest = new JsonObjectRequest(Method.GET,
        url, null,
        new Response.Listener<JSONObject>() {

            @Override
            public void onResponse(JSONObject response) {
                Log.d(TAG, response.toString());
            }
        }, new Response.ErrorListener() {

            @Override
            public void onErrorResponse(VolleyError error) {
                Log.d(TAG, "Error: " + error.getMessage());
            }
});

myRequest.setRetryPolicy(new DefaultRetryPolicy(
        MY_SOCKET_TIMEOUT_MS, 
        DefaultRetryPolicy.DEFAULT_MAX_RETRIES, 
        DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

Try to update the below two parameters as they must be having default values.

innodb_lock_wait_timeout = 50

innodb_rollback_on_timeout = ON

For checking parameter value you can use the below SQL.

SHOW GLOBAL VARIABLES LIKE 'innodb_rollback_on_timeout';

Below is combination of what I've found from SoccerPlayer's post Here and the following link that made it easier for me to attach an xlsx file. Found Here

file = 'File.xlsx'

send_to = 'recipient1 , recipient2'
Cc = 'recipient'
msg = MIMEMultipart()
msg['From'] = send_from

part.set_payload(fp.read())
fp.close()
encoders.encode_base64(part)
part.add_header('Content-Disposition', 'attachment', filename='Name File Here')
msg.attach(part)
smtp = smtplib.SMTP('smtp.gmail.com')

smtp.starttls()
smtp.login(username,password)
smtp.sendmail(send_from, send_to.split(',') + msg['Cc'].split(','), msg.as_string())
smtp.quit()

I was inspired by @AniMenon to write a pythonic more general solution.

mylist = ['x', 3, 'b']
print('[{}]'.format(', '.join(map('{}'.format, mylist))))

It only uses the format method. No trace of str, and it allows for the fine tuning of the elements format. For example, if you have float numbers as elements of the list, you can adjust their format, by adding a conversion specifier, in this case :.2f

mylist = [1.8493849, -6.329323, 4000.21222111]
print("[{}]".format(', '.join(map('{:.2f}'.format, mylist))))

The output is quite decent:

[1.85, -6.33, 4000.21]

There are several decisions to make:

1. The first about resource path:

   • Model the image as a resource on its own:

     • Nested in user (/user/:id/image): the relationship between the user and the image is made implicitly

     • In the root path (/image):

       • The client is held responsible for establishing the relationship between the image and the user, or;

       • If a security context is being provided with the POST request used to create an image, the server can implicitly establish a relationship between the authenticated user and the image.

   • Embed the image as part of the user

2. The second decision is about how to represent the image resource:

   • As Base 64 encoded JSON payload
   • As a multipart payload

This would be my decision track:

• I usually favor design over performance unless there is a strong case for it. It makes the system more maintainable and can be more easily understood by integrators.
• So my first thought is to go for a Base64 representation of the image resource because it lets you keep everything JSON. If you chose this option you can model the resource path as you like.
  • If the relationship between user and image is 1 to 1 I'd favor to model the image as an attribute specially if both data sets are updated at the same time. In any other case you can freely choose to model the image either as an attribute, updating the it via PUT or PATCH, or as a separate resource.
• If you choose multipart payload I'd feel compelled to model the image as a resource on is own, so that other resources, in our case, the user resource, is not impacted by the decision of using a binary representation for the image.

Then comes the question: Is there any performance impact about choosing base64 vs multipart?. We could think that exchanging data in multipart format should be more efficient. But this article shows how little do both representations differ in terms of size.

My choice Base64:

• Consistent design decision
• Negligible performance impact
• As browsers understand data URIs (base64 encoded images), there is no need to transform these if the client is a browser
• I won't cast a vote on whether to have it as an attribute or standalone resource, it depends on your problem domain (which I don't know) and your personal preference.

I'm not sure how FWIX.com is doing it specifically, but I'd wager they are using Custom Overlays.

You need to make sure that the value you pass to the directory argument is an absolute path, corrected for the current location of your application.

The best way to do this is to configure UPLOAD_FOLDER as a relative path (no leading slash), then make it absolute by prepending current_app.root_path:

@app.route('/uploads/<path:filename>', methods=['GET', 'POST'])
def download(filename):
    uploads = os.path.join(current_app.root_path, app.config['UPLOAD_FOLDER'])
    return send_from_directory(directory=uploads, filename=filename)

It is important to reiterate that UPLOAD_FOLDER must be relative for this to work, e.g. not start with a /.

A relative path could work but relies too much on the current working directory being set to the place where your Flask code lives. This may not always be the case.

$(function () {
    $('input[type=file]').change(function () {
        var val = $(this).val().toLowerCase(),
            regex = new RegExp("(.*?)\.(docx|doc|pdf|xml|bmp|ppt|xls)$");

        if (!(regex.test(val))) {
            $(this).val('');
            alert('Please select correct file format');
        }
    });
});

Is it not just a case of applying an appropriate class to each div?

For example:

.firstRowDiv { margin:0px 10px 10px 0px; }
.secondRowDiv { margin:0px 10px 0px 0px; }

This depends on if you know in advance which div to apply which class to.

What is it exactly?

An FCM Token, or much commonly known as a registrationToken like in google-cloud-messaging. As described in the GCM FCM docs:

An ID issued by the GCM connection servers to the client app that allows it to receive messages. Note that registration tokens must be kept secret.

How can I get that token?

Update: The token can still be retrieved by calling getToken(), however, as per FCM's latest version, the FirebaseInstanceIdService.onTokenRefresh() has been replaced with FirebaseMessagingService.onNewToken() -- which in my experience functions the same way as onTokenRefresh() did.

Old answer:

As per the FCM docs:

On initial startup of your app, the FCM SDK generates a registration token for the client app instance. If you want to target single devices or create device groups, you'll need to access this token.

You can access the token's value by extending FirebaseInstanceIdService. Make sure you have added the service to your manifest, then call getToken in the context of onTokenRefresh, and log the value as shown:

@Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);

    // TODO: Implement this method to send any registration to your app's servers.
    sendRegistrationToServer(refreshedToken);
}

The onTokenRefreshcallback fires whenever a new token is generated, so calling getToken in its context ensures that you are accessing a current, available registration token. FirebaseInstanceID.getToken() returns null if the token has not yet been generated.

After you've obtained the token, you can send it to your app server and store it using your preferred method. See the Instance ID API reference for full detail on the API.

"response.redirect" and "server.transfer" helps to transfer user from one page to other page while the page is executing. But the way they do this transfer / redirect is very different.

In case you are visual guy and would like see demonstration rather than theory I would suggest to see the below facebook video which explains the difference in a more demonstrative way.

https://www.facebook.com/photo.php?v=762186150488997

The main difference between them is who does the transfer. In "response.redirect" the transfer is done by the browser while in "server.transfer" it’s done by the server. Let us try to understand this statement in a more detail manner.

In "Server.Transfer" following is the sequence of how transfer happens:-

1.User sends a request to an ASP.NET page. In the below figure the request is sent to "WebForm1" and we would like to navigate to "Webform2".

2.Server starts executing "Webform1" and the life cycle of the page starts. But before the complete life cycle of the page is completed “Server.transfer” happens to "WebForm2".

3."Webform2" page object is created, full page life cycle is executed and output HTML response is then sent to the browser.

While in "Response.Redirect" following is the sequence of events for navigation:-

1.Client (browser) sends a request to a page. In the below figure the request is sent to "WebForm1" and we would like to navigate to "Webform2".

2.Life cycle of "Webform1" starts executing. But in between of the life cycle "Response.Redirect" happens.

3.Now rather than server doing a redirect , he sends a HTTP 302 command to the browser. This command tells the browser that he has to initiate a GET request to "Webform2.aspx" page.

4.Browser interprets the 302 command and sends a GET request for "Webform2.aspx".

In other words "Server.Transfer" is executed by the server while "Response.Redirect" is executed by thr browser. "Response.Redirect" needs to two requests to do a redirect of the page.

So when to use "Server.Transfer" and when to use "Response.Redirect" ?

Use "Server.Transfer" when you want to navigate pages which reside on the same server, use "Response.Redirect" when you want to navigate between pages which resides on different server and domain.

Below is a summary table of which chalks out differences and in which scenario to use.

a less "Math" oriented approach ,but should also work , this way, the < / > test is exposed (maybe more understandable than minimaxing) but it really depends on what you mean by "readable"

function clamp(num, min, max) {
  return num <= min ? min : num >= max ? max : num;
}

What about a wrapper around your existing code:

public Collection<File> getMatchingFiles( String directory, String extension ) {
     return new ArrayList<File>()( 
         getAllFilesThatMatchFilenameExtension( directory, extension ) );
 }

I will throw a warning though. If you can live with that warning, then you're done.

import re
p = re.compile("[a-z]")
for m in p.finditer('a1b2c3d4'):
    print(m.start(), m.group())

Update

There is a new and very simple solution for this:

It allows you to use any kind of input filter on a text <input>, including various numeric filters. This will correctly handle Copy+Paste, Drag+Drop, keyboard shortcuts, context menu operations, non-typeable keys, and all keyboard layouts.

See this answer or try it yourself on JSFiddle.

jquery.numeric plugin

I've successfully implemented many forms with the jquery.numeric plugin.

$(document).ready(function(){
    $(".numeric").numeric();
});

Moreover this works with textareas also!

However, note that Ctrl+A, Copy+Paste (via context menu) and Drag+Drop will not work as expected.

HTML 5

With wider support for the HTML 5 standard, we can use pattern attribute and number type for input elements to restrict number only input. In some browsers (notably Google Chrome), it works to restrict pasting non-numeric content as well. More information about number and other newer input types is available here.

https://medium.com/the-resonant-web/spring-boot-2-0-project-structure-and-best-practices-part-2-7137bdcba7d3

I think this is a good structure. And it is a nicely written blog explaining the mindset of these choices.

Check the config file, the config path is /etc/php5/fpm/pool.d/www.conf, there you'll find the path by config and if you want you can change it.

EDIT:
well you're correct, you need to replace listen = 127.0.0.1:9000 to listen = /var/run/php5-fpm/php5-fpm.sock, then you need to run sudo service php5-fpm restart, and make sure it says that it restarted correctly, if not then make sure that /var/run/ has a folder called php5-fpm, or make it listen to /var/run/php5-fpm.sock cause i don't think the folder inside /var/run is created automatically, i remember i had to edit the start up script to create that folder, otherwise even if you mkdir /var/run/php5-fpm after restart that folder will disappear and the service starting will fail.

You shoud follow the Angular docs and use $sce - $sce is a service that provides Strict Contextual Escaping services to AngularJS. Here is a docs: http://docs-angularjs-org-dev.appspot.com/api/ng.directive:ngBindHtmlUnsafe

Let's take an example with asynchroniously loading Eventbrite login button

In your controller:

someAppControllers.controller('SomeCtrl', ['$scope', '$sce', 'eventbriteLogin', 
  function($scope, $sce, eventbriteLogin) {

    eventbriteLogin.fetchButton(function(data){
      $scope.buttonLogin = $sce.trustAsHtml(data);
    });
  }]);

In your view just add:

<span ng-bind-html="buttonLogin"></span>

In your services:

someAppServices.factory('eventbriteLogin', function($resource){
   return {
        fetchButton: function(callback){
            Eventbrite.prototype.widget.login({'app_key': 'YOUR_API_KEY'}, function(widget_html){
                callback(widget_html);
            })
      }
    }
});

Use the RIGHT function... e.g.

DECLARE @testnum TINYINT
SET @testnum = 3
PRINT RIGHT('00' + CONVERT(VARCHAR(2), @testnum), 2)

1. You can simply override BaseActivity onActivityResult on fragment baseActivity.startActivityForResult .

2. On BaseActivity add interface and override onActivityResult.

   private OnBaseActivityResult baseActivityResult;
   public static final int BASE_RESULT_RCODE = 111;
   public interface OnBaseActivityResult{
       void onBaseActivityResult(int requestCode, int resultCode, Intent data);
      }
   }
   
   @Override
   protected void onActivityResult(int requestCode, int resultCode, Intent data) {
   super.onActivityResult(requestCode, resultCode, data);
   if(getBaseActivityResult() !=null && requestCode == BASE_RESULT_RCODE){
       getBaseActivityResult().onBaseActivityResult(requestCode, resultCode, data);
       setBaseActivityResult(null);
   }
   

3. On Fragment implements OnBaseActivityResult

   @Override
   public void onBaseActivityResult(int requestCode, int resultCode, Intent data) {
   Log.d("RQ","OnBaseActivityResult");
   if (data != null) {
       Log.d("RQ","OnBaseActivityResult + Data");
       Bundle arguments = data.getExtras();
     }
   }
   

This workaround will do the trick.

Nesting a stackpanel will cause the textbox to wrap properly:

<Viewbox Margin="120,0,120,0">
    <StackPanel Orientation="Vertical" Width="400">
        <TextBlock x:Name="subHeaderText" 
                   FontSize="20" 
                   TextWrapping="Wrap" 
                   Foreground="Black"
                   Text="Lorem ipsum dolor, lorem isum dolor,Lorem ipsum dolor sit amet, lorem ipsum dolor sit amet " />
    </StackPanel>
</Viewbox>

UTF-8 is prepared for world domination, Latin1 isn't.

If you're trying to store non-Latin characters like Chinese, Japanese, Hebrew, Russian, etc using Latin1 encoding, then they will end up as mojibake. You may find the introductory text of this article useful (and even more if you know a bit Java).

Note that full 4-byte UTF-8 support was only introduced in MySQL 5.5. Before that version, it only goes up to 3 bytes per character, not 4 bytes per character. So, it supported only the BMP plane and not e.g. the Emoji plane. If you want full 4-byte UTF-8 support, upgrade MySQL to at least 5.5 or go for another RDBMS like PostgreSQL. In MySQL 5.5+ it's called utf8mb4.

If your arrays are character arrays(which seems to be the case), You need a strcat().
Your destination array should have enough space to accommodate the appended data though.

In C++, You are much better off using std::string and then you can use std::string::append()

You may use the class java.util.Random with method

char c = (char)(rnd.nextInt(128-32))+32 

20x to get Bytes, which you interpret as ASCII. If you're fine with ASCII.

32 is the offset, from where the characters are printable in general.

Another possibility is to select the Install Dependencies checkbox In the R package installer, on the bottom right:

One of Androids powerful feature is the AsyncTask class.

To work with it, you have to first extend it and override doInBackground(...). doInBackground automatically executes on a worker thread, and you can add some listeners on the UI Thread to get notified about status update, those functions are called: onPreExecute(), onPostExecute() and onProgressUpdate()

You can find a example here.

Refer to below post for other alternatives:

Handler vs AsyncTask vs Thread

Easy solution for .Net Core WinForms / WPF / .Net Standard Class Library projects

step 1: Install System.Configuration.ConfigurationManager by Nuget Manager

step 2: Add a new App.Config file

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="Bodrum" value="Yalikavak" />    
  </appSettings>
</configuration>

step3: Get the value

string value = ConfigurationManager.AppSettings.Get("Bodrum");
// value is Yalikavak

If you are calling it from a Class Library then add the App.Config file on your Main Project.

You can use strstr to do this.

echo strstr($str, 'www/audio');

alternative solution with awk and double parenthesis:

FILENAME=file.txt
SIZE=$(du -sb $FILENAME | awk '{ print $1 }')

if ((SIZE<90000)) ; then 
    echo "less"; 
else 
    echo "not less"; 
fi

Screen resolution is total no of pixel in screen. Following program will extract the screen resolution of the device. It will print screen width and height. Those values are in pixel.

public static Point getScreenResolution(Context context) {
// get window managers
WindowManager manager =  (WindowManager)context.getSystemService(Context.WINDOW_SERVICE);
Display display = manager.getDefaultDisplay();
Point point = new Point();
display.getSize(point);

 // get width and height
 int width = point.x;
 int height = point.y;

 return point;

}

Use the following code this works fine in Native Nodejs

http.createServer(function (req, res) {
var q = url.parse(req.url, true);
if (q.pathname === '/') {
  //Home page code
} else if (q.pathname === '/redirect-to-google') {
  res.writeHead(301, { "Location": "http://google.com/" });
  return res.end();
} else if (q.pathname === '/redirect-to-interal-page') {
  res.writeHead(301, { "Location": "/path/within/site" });
  return res.end();
} else {
    //404 page code
}
res.end();
}).listen(8080);

Python's *.py file is just a text file in which you write some lines of code. When you try to execute this file using say "python filename.py"

This command invokes Python Virtual Machine. Python Virtual Machine has 2 components: "compiler" and "interpreter". Interpreter cannot directly read the text in *.py file, so this text is first converted into a byte code which is targeted to the PVM (not hardware but PVM). PVM executes this byte code. *.pyc file is also generated, as part of running it which performs your import operation on file in shell or in some other file.

If this *.pyc file is already generated then every next time you run/execute your *.py file, system directly loads your *.pyc file which won't need any compilation(This will save you some machine cycles of processor).

Once the *.pyc file is generated, there is no need of *.py file, unless you edit it.

In my case margin auto works fine.

p {
    font: 22px/24px Ubuntu;
    margin:auto 0px;
}

Use a scalar-valued UDF, not a table-value one, then you can use it in a SELECT as you want.

consider

data={'fld':'hello'}

now

jsonify(data)

will yield {'fld':'hello'} and

json.dumps(data)

gives

"<html><body><p>{'fld':'hello'}</p></body></html>"

This seems to be old post but still I wanted to share how this issue got fixed for me.

For users, who do not have admin access and when they open a command prompt, it runs under the user privilege. It means, you may have path like C:\Users\

so when trying C:\Users\XYZ>mvn --version , it actually search the JAVA_HOME path from user variables not system variables in Environment Variables.

So, In order to fix this, we need to create a environment variable for JAVA_HOME in user variables.

Hope, this helps someone.

byte[] a = new byte[50];

char [] cArray= System.Text.Encoding.ASCII.GetString(a).ToCharArray();

From the URL thedixon posted

http://bytes.com/topic/c-sharp/answers/250261-byte-char

You cannot ToCharArray the byte without converting it to a string first.

To quote Jon Skeet there

There's no need for the copying here - just use Encoding.GetChars. However, there's no guarantee that ASCII is going to be the appropriate encoding to use.

• Install qt using:

  sudo apt install qt5-qmake
  

• Open ~/.bashrc file:

  vim ~/.bashrc
  

• Added the path below to the ~/.bashrc file:

  export PATH="/opt/Qt/5.15.1/gcc_64/bin/:$PATH"
  

• Execute/load a ~/.bashrc file in your current shell

  source ~/.bashrc`
  

• Try now qmake by using the version command below:

  qmake --version
  

I think the load event is right. What is not right is the way you use to retreive the content from iframe content dom.

What you need is the html of the page loaded in the iframe not the html of the iframe object.

What you have to do is to access the content document with iFrameObj.contentDocument. This returns the dom of the page loaded inside the iframe, if it is on the same domain of the current page.

I would retreive the content before removing the iframe.

I've tested in firefox and opera.

Then i think you can retreive your data with $(childDom).html() or $(childDom).find('some selector') ...

For questions like this, it is always worth taking a look in the manual first. Date and time functions in the mySQL manual

CURDATE() returns the DATE part of the current time. Manual on CURDATE()

NOW() returns the date and time portions as a timestamp in various formats, depending on how it was requested. Manual on NOW().

A SQLite database is a regular file. It is created in your script current directory.

v-model is for two way bindings means: if you change input value, the bound data will be changed and vice versa. But v-bind:value is called one way binding that means: you can change input value by changing bound data but you can't change bound data by changing input value through the element.

v-model is intended to be used with form elements. It allows you to tie the form element (e.g. a text input) with the data object in your Vue instance.

Example: https://jsfiddle.net/jamesbrndwgn/j2yb9zt1/1/

v-bind is intended to be used with components to create custom props. This allows you to pass data to a component. As the prop is reactive, if the data that’s passed to the component changes then the component will reflect this change

Example: https://jsfiddle.net/jamesbrndwgn/ws5kad1c/3/

4 Things You Must Do When Putting HTML in JSON:

1) Escape quotation marks used around HTML attributes like so <img src=\"someimage.png\" />

2) Escape the forward slash in HTML end tags. <div>Hello World!<\/div>. This is an ancient artifact of an old HTML spec that didn't want HTML parsers to get confused when putting strings in a <SCRIPT> tag. For some reason, today’s browsers still like it.

3) This one was totally bizarre. You should include a space between the tag name and the slash on self-closing tags. I have no idea why this is, but on MOST modern browsers, if you try using javascript to append a <li> tag as a child of an unordered list that is formatted like so: <ul/>, it won't work. It gets added to the DOM after the ul tag. But, if the code looks like this: <ul /> (notice the space before the /), everything works fine. Very strange indeed.

4) Be sure to encode any quotation marks that might be included in (bad) HTML content. This is the only thing that would really break the JSON by accidentally terminating the string early. Any " characters should be encoded as " if it is meant to be included as HTML content.

I also faced it and encorrected it like below successfully.

File > Settings > Build, Execution, Deployment > Gradle > Use local gradle distribution

When you log in to your developer account, you can find a link at the bottom of the download section for Xcode that says "Looking for an older version of Xcode?". In there you can find download links to older versions of Xcode and other developer tools

There are a several things you need to address to get it working

1. The name is wrong its not @ouput its @code
2. You need to set the parameter direction to Output.
3. Don't use AddWithValue since its not supposed to have a value just you Add.
4. Use ExecuteNonQuery if you're not returning rows

Try

SqlParameter output = new SqlParameter("@code", SqlDbType.Int);
output.Direction = ParameterDirection.Output;
cmd.Parameters.Add(output);
cmd.ExecuteNonQuery();
MessageBox.Show(output.Value.ToString());

If you can't find your version with brew search <formula>, you can also try going over the commit logs for your formula to find the version you want:

here is an example for installing an older version of nginx via brew:

• ngxnx formula commit log

• see nginx: update 1.6.3 bottle eba75b9a1a474b9fc4df30bd0a32637fa31ec049

From there, we can install 1.6.3 with the sha and raw git url:

brew install https://raw.githubusercontent.com/Homebrew/homebrew/eba75b9a1a474b9fc4df30bd0a32637fa31ec049/Library/Formula/nginx.rb

This is how I am using it. And it is working fantastically -

public enum Button {
        REPORT_ISSUES(0),
        CANCEL_ORDER(1),
        RETURN_ORDER(2);

        private int value;

        Button(int value) {
            this.value = value;
        }

        public int getValue() {
            return value;
        }
    }

And the switch-case as shown below

@Override
public void onClick(MyOrderDetailDelgate.Button button, int position) {
    switch (button) {
        case REPORT_ISSUES: {
            break;
        }
        case CANCEL_ORDER: {
            break;
        }
        case RETURN_ORDER: {
            break;
        }
    }
}

I don't know if I understand your question, but maybe:

foreach ($_POST as $id=>$value)
    if (strncmp($id,'id[',3) $info[rtrim(ltrim($id,'id['),']')]=$_POST[$id];

would help

That is if you really want to have a different name (id[key]) on each checkbox of the html form (not very efficient). If not you can just name them all the same, i.e. 'id' and iterate on the (selected) values of the array, like: foreach ($_POST['id'] as $key=>$value)...

We can break both a $(selector).each() loop and a $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration.

return false; // this is equivalent of 'break' for jQuery loop

return;       // this is equivalent of 'continue' for jQuery loop

Note that $(selector).each() and $.each() are different functions.

References:

• $(selector).each()
• $.each()
• What is the difference between $.each(selector) and $(selector).each()

There are two properties in a TabControl control that manages which tab page is selected.

SelectedIndex which offer the possibility to select it by index (an integer starting from 0 to the number of tabs you have minus one).

SelectedTab which offer the possibility to selected the tab object itself to select.

Setting either of these property will change the currently displayed tab.

Alternatively you can also use the Select method. It comes in three flavour, one where you pass the index of the tab, another the TabPage object itself and the last one a string representing the tab's name.

For Eclipse (Helios) the following procedure works - I've tried it:

1. Go to Help -> Install New software
2. Add the following link: http://download.eclipse.org/technology/m2e/releases/1.3
3. After results found unselect "sl4j... (optional)"
4. Next

From the fine manual:

ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;

There's no need to specify the type when you're just changing the nullability.

on my system i had to insert apc.shm_size = 64M into /usr/local/etc/php.ini (FreeBSD 9.1) then when i looked at apc.php (which i copied from /usr/local/share/doc/APC/apc.php to /usr/local/www/apache24/data) i found that the cache size had increased from the default of 32M to 64M and i was no longer getting a large cache full count

These instructions are for XCode 6.4 (since I couldn't find the update for the recent versions even this was a bit outdated)

a) Part on the developers' website:

Sign in into: https://developer.apple.com/

Member Center

Certificates, Identifiers & Profiles

Certificates>All

Click "+" to add, and then follow the instructions. You will need to open "Keychain Access.app", there under "Keychain Access" menu > "Certificate Assistant>", choose "Request a Certificate From a Certificate Authority" etc.

b) XCode part:

After all, you need to go to XCode, and open XCode>Preferences..., choose your Apple ID > View Details... > click that rounded arrow to update as well as "+" to check for iOS Distribution or iOS Developer Signing Identities.

Below is the code for pass unique notification id:

//"CommonUtilities.getValudeFromOreference" is the method created by me to get value from savedPreferences.
String notificationId = CommonUtilities.getValueFromPreference(context, Global.NOTIFICATION_ID, "0");
int notificationIdinInt = Integer.parseInt(notificationId);

notificationManager.notify(notificationIdinInt, notification);

// will increment notification id for uniqueness
notificationIdinInt = notificationIdinInt + 1;
CommonUtilities.saveValueToPreference(context, Global.NOTIFICATION_ID, notificationIdinInt + "");
//Above "CommonUtilities.saveValueToPreference" is the method created by me to save new value in savePreferences.

Reset notificationId in savedPreferences at specific range like I have did it at 1000. So it will not create any issues in future. Let me know if you need more detail information or any query. :)

EDIT

You can rename fields using:

ALTER TABLE xyz CHANGE manufacurerid manufacturerid INT

First of All Theory

1. Big O = Upper Limit O(n)

2. Theta = Order Function - theta(n)

3. Omega = Q-Notation(Lower Limit) Q(n)

Why People Are so Confused?

In many Blogs & Books How this Statement is emphasised is Like

"This is Big O(n^3)" etc.

and people often Confuse like weather

O(n) == theta(n) == Q(n)

But What Worth keeping in mind is They Are Just Mathematical Function With Names O, Theta & Omega

so they have same General Formula of Polynomial,

Let,

f(n) = 2n4 + 100n2 + 10n + 50 then,

g(n) = n4, So g(n) is Function which Take function as Input and returns Variable with Biggerst Power,

Same f(n) & g(n) for Below all explainations

Big O - Function (Provides Upper Bound)

Big O(n4) = 3n4, Because 3n4 > 2n4

3n4 is value of Big O(n4) Just like f(x) = 3x

n4 is playing a role of x here so,

Replacing n4 with x'so, Big O(x') = 2x', Now we both are happy General Concept is

So 0 = f(n) = O(x')

O(x') = cg(n) = 3n4

Putting Value,

0 = 2n4 + 100n2 + 10n + 50 = 3n4

3n4 is our Upper Bound

Theta(n) Provides Lower Bound

Theta(n4) = cg(n) = 2n4 Because 2n4 = Our Example f(n)

2n4 is Value of Theta(n4)

so, 0 = cg(n) = f(n)

0 = 2n4 = 2n4 + 100n2 + 10n + 50

2n4 is our Lower Bound

Omega n - Order Function

This is Calculated to find out that weather lower Bound is similar to Upper bound,

Case 1). Upper Bound is Similar to Lower Bound

if Upper Bound is Similar to Lower Bound, The Average Case is Similar

Example, 2n4 = f(x) = 2n4,
Then Omega(n) = 2n4

Case 2). if Upper Bound is not Similar to Lower Bound

in this case, Omega(n) is Not fixed but Omega(n) is the set of functions with the same order of growth as g(n).

Example 2n4 = f(x) = 3n4, This is Our Default Case,
Then, Omega(n) = c'n4, is a set of functions with 2 = c' = 3

Hope This Explained!!

I was trying to use System.IO.File.OpenWrite(path)

and it did not work because I was only passing OpenWrite() a path to a directory, but it requires a path all the way to the file you want to write. So a full path including the filename.extension at the end needs to be passed into OpenWrite to avoid UnauthorizedAccessException

Width: 100% will break it when you view on a wider are.

Following is Bootstrap's img-responsive

max-width: 100%;

I resolved it by giving permission to the user on each of the directories that you're using, like so:

sudo chown user /home/user/git

and so on.

Node has a concept of Local modules & Global modules

Local modules are located within current project directory.

Global Modules are generally located at user's home directory, though we can change the path where global modules resides.

1. Lists local modules within current dir: npm list
2. Lists global modules : npm list --global OR npm list --g // It will list all the top level modules with its dependencies
3. List only top level(Installed modules) global modules : npm list -g --depth=0

Technically you could do it with a straight TCP socket. I wouldn't recommend it however. I would highly recommend you use Apache HttpClient instead. In its simplest form:

GetMethod get = new GetMethod("http://httpcomponents.apache.org");
// execute method and handle any error responses.
...
InputStream in = get.getResponseBodyAsStream();
// Process the data from the input stream.
get.releaseConnection();

and here is a more complete example.

Possible duplicate: Is there a maven 2 archetype for spring 3 MVC applications?

That said, I would encourage you to think about making your own archetype. The reason is, no matter what you end up getting from someone else's, you can do better in not that much time, and a decent sized Java project is going to end up making a lot of jar projects.

If the url is in a cell in your workbook, you can simply copy the value from that cell:

Private Sub CommandButton1_Click()
    Sheets("Sheet1").Range("A1").Copy
End Sub

(Add a button by using the developer tab. Customize the ribbon if it isn't visible.)

If the url isn't in the workbook, you can use the Windows API. The code that follows can be found here: http://support.microsoft.com/kb/210216

After you've added the API calls below, change the code behind the button to copy to the clipboard:

Private Sub CommandButton1_Click()

No, but you can in Scala! (And then compile that and run it using any Java implementation!!!!)

Now, if you want to do it the easy way in java, use the Apache commons-lang package. Assuming you're using maven, add this dependency to your pom.xml:

    <dependency>
        <groupId>commons-lang</groupId>
        <artifactId>commons-lang</artifactId>
        <version>2.4</version>
    </dependency>

And then use StringUtils.repeat as follows:

import org.apache.commons.lang.StringUtils
...
someNum = sumNum + StringUtils.repeat("0", 3);

Try SelectMany()

var result = iList.SelectMany( i => i );

call me old fashion but why use a 3rd party library for a simple protocol. I've implemented POP3 readers in web based ASP.NET application with System.Net.Sockets.TCPClient and System.Net.Security.SslStream for the encryption and authentication. As far as protocols go, once you open up communication with the POP3 server, there are only a handful of commands that you have to deal with. It is a very easy protocol to work with.

echo dirname(__DIR__);

But note the __DIR__ constant was added in PHP 5.3.0.

According your condition, you can also define some environmental variables, and fetch it via ENV['some-var'] in ruby code, this solution may not fit for you, but I hope it may help others.

Example: you can create different files .development_env, .production_env, .test_env and load it according your application environments, check this gen dotenv-rails which automate this for your.

import java.util.List;
import java.util.stream.Stream;

class Main {

    public static void main(String[] args) {
        // Create a stream of strings from list of strings
        Stream<String> myStreamOfStrings = List.of("lala", "foo", "bar").stream();

        // Convert stream to array by using toArray method
        String[] myArrayOfStrings = myStreamOfStrings.toArray(String[]::new);

        // Print results
        for (String string : myArrayOfStrings) {
            System.out.println(string);
        }
    }
}

You can just use the TimeOfDay property of date time, which is TimeSpan type:

DateTime.TimeOfDay

This property has been around since .NET 1.1

In another case I'm able to use template literal ES6 with backticks, so for yours could be set as:

<img v-bind:src="`${imgPreUrl()}img/logo.png`">

None of the answers here solved my issue (as at February 2020), so I raised an issue at https://issues.apache.org/jira/browse/NETBEANS-3903 and Netbeans fixed the issue!

They're working on a pull request so the fix will be in a future .dmg installer soon, but in the meantime you can copy a file referenced in the bug and replace one in your netbeans modules folder.

Tip - if you right click on Applications > Netbeans and choose Show Package Contents then you can find and replace the file org-netbeans-modules-tomcat5.jar that they refer to in your Netbeans folder, e.g. within /Applications/NetBeans/Apache NetBeans 11.2.app/Contents/Resources/NetBeans/netbeans/enterprise/modules

Well, it costed me 2 days to figure out the problem. In short, by default you shall just keep the max version to be the highest level you had downloaded, says, Level 23 (Android M) for my case.

otherwise you will get these errors. You have to go to project properties of both your project and appcompat to change the target version.

sigh.

jQuery 1.4.1 now supports "hover" for live() events, but only with one event handler function:

$("table tr").live("hover",

function () {

});

Alternatively, you can provide two functions, one for mouseenter and one for mouseleave:

$("table tr").live({
    mouseenter: function () {

    },
    mouseleave: function () {

    }
});

So use the short cut keys , Press ctrl + shift + I and then Click on Magnifying Option on Left side and Then Hover the mouse cursor and you will be navigate to proper way

ActiveX is supported by Chrome.

Chrome check parameters defined in : control panel/Internet option/Security.

Nevertheless,if it's possible to define four different area with IE, Chrome only check "Internet" area.

Download Microsoft Drivers for PHP for SQL Server. Extract the files and use one of:

File                             Thread Safe         VC Bulid
php_sqlsrv_53_nts_vc6.dll           No                  VC6
php_sqlsrv_53_nts_vc9.dll           No                  VC9
php_sqlsrv_53_ts_vc6.dll            Yes                 VC6
php_sqlsrv_53_ts_vc9.dll            Yes                 VC9

You can see the Thread Safety status in phpinfo().

Add the correct file to your ext directory and the following line to your php.ini:

extension=php_sqlsrv_53_*_vc*.dll

Use the filename of the file you used.

As Gordon already posted this is the new Extension from Microsoft and uses the sqlsrv_* API instead of mssql_*

Update:
On Linux you do not have the requisite drivers and neither the SQLSERV Extension.
Look at Connect to MS SQL Server from PHP on Linux? for a discussion on this.

In short you need to install FreeTDS and YES you need to use mssql_* functions on linux. see update 2

To simplify things in the long run I would recommend creating a wrapper class with requisite functions which use the appropriate API (sqlsrv_* or mssql_*) based on which extension is loaded.

Update 2: You do not need to use mssql_* functions on linux. You can connect to an ms sql server using PDO + ODBC + FreeTDS. On windows, the best performing method to connect is via PDO + ODBC + SQL Native Client since the PDO + SQLSRV driver can be incredibly slow.

A simple workaround:

If a container has only one top level child, then you can specify alignment property for the child and give it any available value. it'll fill all the space in the container.

Container(color:Colors.white,height:200.0,width:200.0,
 child:Container(
    color: Colors.yellow,
    alignment:Alignment.[any_available_option] // make the yellow child match the parent size
   )
)

Another way:

Container(color:Colors.white,height:200.0,width:200.0,
 child:Container(
    color: Colors.yellow,
    constraints:  BoxConstraints.expand(height: 100.0), // height will be 100 dip and width will be match parent
   )
)

You can add some code like this

ListView.builder{
   shrinkWrap: true,
}

At least in case of EclipseLink 10g and 11g differ. Since 11g it is not recommended to use first_rows hint for pagination queries.

See "Is it possible to disable jpa hints per particular query". Such a query should not be used in 11g.

SELECT * FROM (
  SELECT /*+ FIRST_ROWS */ a.*, ROWNUM rnum  FROM (
    SELECT * FROM TABLES INCLUDING JOINS, ORDERING, etc.) a
  WHERE ROWNUM <= 10 )
WHERE rnum > 0;

But there can be other nuances.

In my case I had to do this

npm install @types/jquery --save-dev // install jquery type as dev dependency so TS can compile properly
npm install jquery --save // save jquery as a dependency

Then in the script file A.ts

import * as $ from "jquery";
... jquery code ...

I normally use the 'back tick' feature of bash

export NUM_LINES=`wc -l filename`

Note the 'tick' is the 'back tick' e.g. ` not the normal single quote

you can do like follows. Remember, IsNull is a function which returns TRUE if the parameter passed to it is null, and false otherwise.

Not IsNull(Fields!W_O_Count.Value)

My following JS solution is better than the other approaches here because it ensures that it will always say 'open' when the target is closed, and vice versa.

HTML:

<a href="#collapseExample" class="btn btn-primary" data-toggle="collapse" data-toggle-secondary="Close">
    Open
</a>
<div class="collapse" id="collapseExample">
  <div class="well">
    ...
  </div>
</div>

JS:

$('[data-toggle-secondary]').each(function() {
    var $toggle = $(this);
    var originalText = $toggle.text();
    var secondaryText = $toggle.data('toggle-secondary');
    var $target = $($toggle.attr('href'));

    $target.on('show.bs.collapse hide.bs.collapse', function() {
        if ($toggle.text() == originalText) {
            $toggle.text(secondaryText);
        } else {
            $toggle.text(originalText);
        }
    });
});

Examples:

$('[data-toggle-secondary]').each(function() {_x000D_
    var $toggle = $(this);_x000D_
    var originalText = $toggle.text();_x000D_
    var secondaryText = $toggle.data('toggle-secondary');_x000D_
    var $target = $($toggle.attr('href'));_x000D_
_x000D_
    $target.on('show.bs.collapse hide.bs.collapse', function() {_x000D_
        if ($toggle.text() == originalText) {_x000D_
            $toggle.text(secondaryText);_x000D_
        } else {_x000D_
            $toggle.text(originalText);_x000D_
        }_x000D_
    });_x000D_
});

JS Fiddle

Other benefits of this approach:

• the code is DRY and reusable
• each collapse button stays separate
• you only need to put one change into the HTML: adding the data-toggle-secondary attribute

They aren't comparable.

Ajax (Asynchronous Javascript and XML) is a subset of javascript. Ajax is way for the client-side browser to communicate with the server (for example: retrieve data from a database) without having to perform a page refresh.

jQuery is a javascript library that standardizes the javascript differences cross-browser. jQuery includes some ajax functions.

jquery will provide you with this and more ...

if($("#something").val()){ //do stuff}

It took me a couple of days to pick it up, but it provides you with you with so much more functionality. An example below.

jQuery(document).ready(function() {
    /* finds closest element with class divright/left and 
    makes all checkboxs inside that div class the same as selectAll...
    */
        $("#selectAll").click(function() {
        $(this).closest('.divright').find(':checkbox').attr('checked', this.checked);
    });
});

Update December 8th, 2015 According to Google Support using the

googledrive.com/host/ID

method will be turned off on Aug 31st, 2016.

I just ran into this issue.

The trick is to treat your Google Drive folder like a web host.

Update April 1st, 2015

Google Drive has changed and there's a simple way to direct link to your drive. I left my previous answers below for reference but to here's an updated answer.

1. Create a Public folder in Google Drive.
   
   
2. Share this drive publicly.
   
   
   
   
3. Get your Folder UUID from the address bar when you're in that folder
   
   
4. Put that UUID in this URL
   
   https://googledrive.com/host/<folder UUID>/
5. Add the file name to where your file is located.
   
   https://googledrive.com/host/<folder UUID>/<file name>

Which is intended functionality by Google
new Google Drive Link.

All you have to do is simple get the host URL for a publicly shared drive folder. To do this, you can upload a plain HTML file and preview it in Google Drive to find your host URL.

Here are the steps:

1. Create a folder in Google Drive.
   
   
2. Share this drive publicly.
   
   
   
   
3. Upload a simple HTML file. Add any additional files (subfolders ok)
   
   
   
   
4. Open and "preview" the HTML file in Google Drive
   
   
   
   
5. Get the URL address for this folder
   
   
   
   
6. Create a direct link URL from your URL folder base
   
   
   
   
7. This URL should allow direct downloads of your large files.
   
   

[edit]

I forgot to add. If you use subfolders to organize your files, you simple use the folder name as you would expect in a URL hierarchy.

https://googledrive.com/host/<your public folders id string>/images/my-image.png

What I was looking to do

I created a custom Debian image with Virtual Box for Vagrant. I wanted to share this ".box" file with colleagues so they could put the direct link into their Vagrantfile.

In the end, I needed a direct link to the actual file.

Google Drive problem

If you set the file permissions to be publicly available and create/generate a direct access link by using something like the gdocs2direct tool or just crafting the link yourself:

https://docs.google.com/uc?export=download&id=<your file id>

You will get a cookie based verification code and prompt "Google could not scan this file" prompt, which won't work for things such as wget or Vagrantfile configs.

The code that it generates is a simple code that appends GET query variable ...&confirm=### to the string, but it's per user specific, so it's not like you can copy/paste that query variable for others.

But if you use the above "Web page hosting" method, you can get around that prompt.

I hope that helps!

$element is one of four locals that $compileProvider gives to $controllerProvider which then gets given to $injector. The injector injects locals in your controller function only if asked.

The four locals are:

• $scope
• $element
• $attrs
• $transclude

The official documentation: AngularJS $compile Service API Reference - controller

The source code from Github angular.js/compile.js:

 function setupControllers($element, attrs, transcludeFn, controllerDirectives, isolateScope, scope) {
    var elementControllers = createMap();
    for (var controllerKey in controllerDirectives) {
      var directive = controllerDirectives[controllerKey];
      var locals = {
        $scope: directive === newIsolateScopeDirective || directive.$$isolateScope ? isolateScope : scope,
        $element: $element,
        $attrs: attrs,
        $transclude: transcludeFn
      };

      var controller = directive.controller;
      if (controller == '@') {
        controller = attrs[directive.name];
      }

      var controllerInstance = $controller(controller, locals, true, directive.controllerAs);

In my case, was an environment variable GIT_DIR, which I added to access faster.

This also broke all my local repos in SourceTree :(

Interestingly, base R aggregate's data.frame method is not showcased here, above the formula interface is used, so for completeness:

aggregate(
  x = df1[c("x1", "x2")],
  by = df1[c("year", "month")],
  FUN = sum, na.rm = TRUE
)

More generic use of aggregate's data.frame method:

Since we are providing a

• data.frame as x and
• a list (data.frame is also a list) as by, this is very useful if we need to use it in a dynamic manner, e.g. using other columns to be aggregated and to aggregate by is very simple
• also with custom-made aggregation functions

For example like so:

colsToAggregate <- c("x1")
aggregateBy <- c("year", "month")
dummyaggfun <- function(v, na.rm = TRUE) {
  c(sum = sum(v, na.rm = na.rm), mean = mean(v, na.rm = na.rm))
}

aggregate(df1[colsToAggregate], by = df1[aggregateBy], FUN = dummyaggfun)

I believe this will only appear when running the page locally in this particular case, i.e. you should not see this when loading the apge from a web server.

However if you have permission to do so, you could turn off the prompt for Internet Explorer by following Tools (menu) → Internet Options → Security (tab) → Custom Level (button) → and Disable Automatic prompting for ActiveX controls.

This will of course, only affect your browser.

To quote the great explanation of Eric

What happens? Do you want the list of giraffes to contain a tiger? Do you want a crash? or do you want the compiler to protect you from the crash by making the assignment illegal in the first place? We choose the latter.

But what if you want to choose for a runtime crash instead of a compile error? You would normally use Cast<> or ConvertAll<> but then you will have 2 problems: It will create a copy of the list. If you add or remove something in the new list, this won't be reflected in the original list. And secondly, there is a big performance and memory penalty since it creates a new list with the existing objects.

I had the same problem and therefore I created a wrapper class that can cast a generic list without creating an entirely new list.

In the original question you could then use:

class Test
{
    static void Main(string[] args)
    {
        A a = new C(); // OK
        IList<A> listOfA = new List<C>().CastList<C,A>(); // now ok!
    }
}

and here the wrapper class (+ an extention method CastList for easy use)

public class CastedList<TTo, TFrom> : IList<TTo>
{
    public IList<TFrom> BaseList;

    public CastedList(IList<TFrom> baseList)
    {
        BaseList = baseList;
    }

    // IEnumerable
    IEnumerator IEnumerable.GetEnumerator() { return BaseList.GetEnumerator(); }

    // IEnumerable<>
    public IEnumerator<TTo> GetEnumerator() { return new CastedEnumerator<TTo, TFrom>(BaseList.GetEnumerator()); }

    // ICollection
    public int Count { get { return BaseList.Count; } }
    public bool IsReadOnly { get { return BaseList.IsReadOnly; } }
    public void Add(TTo item) { BaseList.Add((TFrom)(object)item); }
    public void Clear() { BaseList.Clear(); }
    public bool Contains(TTo item) { return BaseList.Contains((TFrom)(object)item); }
    public void CopyTo(TTo[] array, int arrayIndex) { BaseList.CopyTo((TFrom[])(object)array, arrayIndex); }
    public bool Remove(TTo item) { return BaseList.Remove((TFrom)(object)item); }

    // IList
    public TTo this[int index]
    {
        get { return (TTo)(object)BaseList[index]; }
        set { BaseList[index] = (TFrom)(object)value; }
    }

    public int IndexOf(TTo item) { return BaseList.IndexOf((TFrom)(object)item); }
    public void Insert(int index, TTo item) { BaseList.Insert(index, (TFrom)(object)item); }
    public void RemoveAt(int index) { BaseList.RemoveAt(index); }
}

public class CastedEnumerator<TTo, TFrom> : IEnumerator<TTo>
{
    public IEnumerator<TFrom> BaseEnumerator;

    public CastedEnumerator(IEnumerator<TFrom> baseEnumerator)
    {
        BaseEnumerator = baseEnumerator;
    }

    // IDisposable
    public void Dispose() { BaseEnumerator.Dispose(); }

    // IEnumerator
    object IEnumerator.Current { get { return BaseEnumerator.Current; } }
    public bool MoveNext() { return BaseEnumerator.MoveNext(); }
    public void Reset() { BaseEnumerator.Reset(); }

    // IEnumerator<>
    public TTo Current { get { return (TTo)(object)BaseEnumerator.Current; } }
}

public static class ListExtensions
{
    public static IList<TTo> CastList<TFrom, TTo>(this IList<TFrom> list)
    {
        return new CastedList<TTo, TFrom>(list);
    }
}

If you are using just code like this below, you must put just a grave accent at the end of line `.

docker run -d --name rabbitmq `
           -p 5672:5672 `
           -p 15672:15672 `
           --restart=always `
           --hostname rabbitmq-master `
           -v c:\docker\rabbitmq\data:/var/lib/rabbitmq `
           rabbitmq:latest

To avoid accidentally overwriting an existing file use:

using (new FileStream(filename, FileMode.CreateNew)) {}

...and handle the IOException which will occur if the file already exists.

File.Create, which is suggested in other answers, will overwrite the contents of the file if it already exists. In simple cases you could mitigate this using File.Exists(). However something more robust is necessary in scenarios where multiple threads and/or processes are attempting to create files in the same folder simultaneously.

You had better use finish() if you are in Activity, or getActivity().finish() if you are in the Fragment.

If you want to quit the app completely, then use:

getActivity().finish();
System.exit(0);

Other alternative:

JAXBElement<String> element = new JAXBElement<>(new QName("Your localPart"),
                                                String.class, "Your message");

Then:

System.out.println(element.getValue()); // Result: Your message

.. or if you're not sure it should always be 8 digits, you can pass it as a parameter:

>>> '%0*d' % (8, int(bin(6)[2:]))
'00000110'

You can use the null coalescing double question marks to test for nulls in a string or other nullable value type:

textBox1.Text = s ?? "Is null";

The operator '??' asks if the value of 's' is null and if not it returns 's'; if it is null it returns the value on the right of the operator.

More info here: https://msdn.microsoft.com/en-us/library/ms173224.aspx

And also worth noting there's a null-conditional operator ?. and ?[ introduced in C# 6.0 (and VB) in VS2015

textBox1.Text = customer?.orders?[0].description ?? "n/a";

This returns "n/a" if description is null, or if the order is null, or if the customer is null, else it returns the value of description.

More info here: https://msdn.microsoft.com/en-us/library/dn986595.aspx

You are facing issue in

 s1.name="Paolo";

because, in the LHS, you're using an array type, which is not assignable.

To elaborate, from C11, chapter §6.5.16

assignment operator shall have a modifiable lvalue as its left operand.

and, regarding the modifiable lvalue, from chapter §6.3.2.1

A modifiable lvalue is an lvalue that does not have array type, [...]

You need to use strcpy() to copy into the array.

That said, data s1 = {"Paolo", "Rossi", 19}; works fine, because this is not a direct assignment involving assignment operator. There we're using a brace-enclosed initializer list to provide the initial values of the object. That follows the law of initialization, as mentioned in chapter §6.7.9

Each brace-enclosed initializer list has an associated current object. When no designations are present, subobjects of the current object are initialized in order according to the type of the current object: array elements in increasing subscript order, structure members in declaration order, and the first named member of a union.[....]

I had a similar problem (firefox v34) with simple strings like:

var myInt = parseInt("b4");

So I came up with a quick hack of:

var intVal = ("" + val).replace(/[^0-9]/gi, "");

And then got all stupid complicated to deal with floats + ints for non-simple stuff:

var myval = "12.34";

function slowParseNumber(val, asInt){
    var ret = Number( ("" + val).replace(/[^0-9\.]/gi, "") );
    return asInt ? Math.floor(ret) : ret;
}
var floatVal = slowParseNumber(myval);

var intVal = slowParseNumber(myval, true);
console.log(floatVal, intVal);

It will return 0 for things like:

var intVal = slowParseNumber("b"); // yeilds 0

From the node.js documentation, "To have a module execute code multiple times, export a function, and call that function", you could use node.js module.export and have a single file to manage the db connections.You can find more at Node.js documentation. Let's say db.js file be like:

    const mysql = require('mysql');

    var connection;

    module.exports = {

    dbConnection: function () {

        connection = mysql.createConnection({
            host: "127.0.0.1",
            user: "Your_user",
            password: "Your_password",
            database: 'Your_bd'
        });
        connection.connect();
        return connection;
    }

    };

Then, the file where you are going to use the connection could be like useDb.js:

const dbConnection = require('./db');

var connection;

function callDb() {

    try {

        connection = dbConnectionManager.dbConnection();

        connection.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
            if (!error) {

                let response = "The solution is: " + results[0].solution;
                console.log(response);

            } else {
                console.log(error);
            }
        });
        connection.end();


    } catch (err) {
        console.log(err);
    }
}

To display dialog box, you can use the following code. This is to display a simple AlertDialog box with multiple check boxes:

AlertDialog.Builder alertDialog= new AlertDialog.Builder(MainActivity.this); .
            alertDialog.setTitle("this is a dialog box ");
            alertDialog.setPositiveButton("ok", new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    // TODO Auto-generated method stub
                    Toast.makeText(getBaseContext(),"ok ive wrote this 'ok' here" ,Toast.LENGTH_SHORT).show();

                }
            });
            alertDialog.setNegativeButton("cancel", new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    // TODO Auto-generated method stub
                        Toast.makeText(getBaseContext(), "cancel ' comment same as ok'", Toast.LENGTH_SHORT).show();


                }
            });
            alertDialog.setMultiChoiceItems(items, checkedItems, new DialogInterface.OnMultiChoiceClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                    // TODO Auto-generated method stub
                    Toast.makeText(getBaseContext(), items[which] +(isChecked?"clicked'again i've wrrten this click'":"unchecked"),Toast.LENGTH_SHORT).show();

                }
            });
            alertDialog.show();

Heading

Whereas if you are using the showDialog function to display different dialog box or anything as per the arguments passed, you can create a self function and can call it under the onClickListener() function. Something like:

 public CharSequence[] items={"google","Apple","Kaye"};
public boolean[] checkedItems=new boolean[items.length];
Button bt;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    bt=(Button) findViewById(R.id.bt);
    bt.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            display(0);             
        }       
    });
}

and add the code of dialog box given above in the function definition.

As of 2020 and Jackson 2.10.1 there's no need for any special code, it's just a matter of telling Jackson what you want:

ObjectMapper objectMapper = new ObjectMapper();

// Register module that knows how to serialize java.time objects
// Provided by jackson-datatype-jsr310
objectMapper.registerModule(new JavaTimeModule());

// Ask Jackson to serialize dates as String (ISO-8601 by default)
objectMapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

This has already been mentioned in this answer, I'm adding a unit test verifying the functionality:

import com.fasterxml.jackson.annotation.JsonFormat;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import lombok.Data;
import org.junit.jupiter.api.Test;

import java.time.LocalDate;

import static org.junit.jupiter.api.Assertions.assertEquals;

public class LocalDateSerializationTest {

    @Data
    static class TestBean {
        // Accept default ISO-8601 format
        LocalDate birthDate;
        // Use custom format
        @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "dd/MM/yyyy")
        LocalDate birthDateWithCustomFormat;
    }

    @Test
    void serializeDeserializeTest() throws JsonProcessingException {
        ObjectMapper objectMapper = new ObjectMapper();

        // Register module that knows how to serialize java.time objects
        objectMapper.registerModule(new JavaTimeModule());

        // Ask Jackson to serialize dates as String (ISO-8601 by default)
        objectMapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

        // The JSON string after serialization
        String json = "{\"birthDate\":\"2000-01-02\",\"birthDateWithCustomFormat\":\"03/02/2001\"}";

        // The object after deserialization
        TestBean object = new TestBean();
        object.setBirthDate(LocalDate.of(2000, 1, 2));
        object.setBirthDateWithCustomFormat(LocalDate.of(2001, 2, 3));

        // Assert serialization
        assertEquals(json, objectMapper.writeValueAsString(object));

        // Assert deserialization
        assertEquals(object, objectMapper.readValue(json, TestBean.class));
    }
}

TestBean uses Lombok to generate the boilerplate for the bean.

2020 UPDATE

You can use .scroll() to easily scroll elements or window. It has a built-in smooth scroll effect so basically the code couldn't be simpler.

Standard properties:

var options = {
    top:       0,        // Number of pixels along the Y axis to scroll the window or element
    left:      0,        // Number of pixels along the X axis to scroll the window or element.
    behavior:  'smooth'  // ('smooth'|'auto') - animate smoothly, or move in a single jump
}

Avoid depending on host OS or JVM for default time zone

I recommend you write all your code to explicitly state the desired/expected time zone. You need not depend on the JVM’s current default time zone. And be aware that the JVM’s current default time zone can change at any moment during runtime, with any code in any thread of any app calling TimeZone.setDefault. Such a call affects all apps within that JVM immediately.

java.time

Some of the other Answers were correct, but are now outmoded. The terrible date-time classes bundled with the earliest versions of Java were flawed, written by people who did not understand the complexities and subtleties of date-time handling.

The legacy date-time classes have been supplanted by the java.time classes defined in JSR 310.

To represent a time zone, use ZoneId. To represent an offset-from-UTC, use ZoneOffset. An offset is merely a number of hour-minutes-seconds ahead or behind the prime meridian. A time zone is much more. A time zone is a history of the past, present, and future changes to the offset used by the people of a particular region.

I need to force any time related operations to GMT/UTC

For an offset of zero hours-minutes-seconds, use the constant ZoneOffset.UTC.

Instant

To capture the current moment in UTC, use an Instant. This class represent a moment in UTC, always in UTC by definition.

Instant instant = Instant.now() ;  // Capture current moment in UTC.

ZonedDateTime

To see that same moment through the wall-clock time used by the people of a particular region, adjust into a time zone. Same moment, same point on the timeline, different wall-clock time.

ZoneId z = ZoneId.of( "Asia/Tokyo" ) ;
ZonedDateTime zdt = instant.atZone( z ) ;

Database

You mention a database.

To retrieve a moment from the database, your column should be of a data type akin to the SQL-standard TIMESTAMP WITH TIME ZONE. Retrieve an object rather than a string. In JDBC 4.2 and later, we can exchange java.time objects with the database. The OffsetDateTime is required by JDBC, while Instant & ZonedDateTime are optional.

OffsetDateTime odt = myResultSet.getObject( … , OffsetDateTime.class ) ;

In most databases and drivers, I would guess that you will get the moment as seen in UTC. But if not, you can adjust in either of two ways:

• Extract a Instant: odt.toInstant()
• Adjust from the given offset to an offset of zero: OffsetDateTime odtUtc = odt.withOffsetSameInstant( ZoneOffset.UTC ) ;`.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

If you're looking for something more straight forward to implement (and it doesn't include pie/donut charts) then I recommend WilliamChart. Specially if motion takes an important role in your app design. In other hand if you want featured charts, then go for MPAndroidChart.

Nice way to handle not found error in Django.

https://docs.djangoproject.com/en/3.1/topics/http/shortcuts/#get-object-or-404

from django.shortcuts import get_object_or_404

def get_data(request):
    obj = get_object_or_404(Model, pk=1)

Just using replace:

var text = 'Hello World';_x000D_
    _x000D_
new_text = text.replace(' ', '_');_x000D_
    _x000D_
console.log(new_text);

This is not code golf, but here is my shortest trick, using types.SimpleNamespace as the container for JSON objects.

Compared to the leading namedtuple solution, it is:

• probably faster/smaller as it does not create a class for each object
• shorter
• no rename option, and probably the same limitation on keys that are not valid identifiers (uses setattr under the covers)

Example:

from __future__ import print_function
import json

try:
    from types import SimpleNamespace as Namespace
except ImportError:
    # Python 2.x fallback
    from argparse import Namespace

data = '{"name": "John Smith", "hometown": {"name": "New York", "id": 123}}'

x = json.loads(data, object_hook=lambda d: Namespace(**d))

print (x.name, x.hometown.name, x.hometown.id)

Update 2018-04-20: it seems that OP @Joshkunz was asking for finding which months are between two dates, instead of "how many months" are between two dates. So I am not sure why @JohnLaRooy is upvoted for more than 100 times. @Joshkunz indicated in the comment under the original question he wanted the actual dates [or the months], instead of finding the total number of months.

So it appeared the question wanted, for between two dates 2018-04-11 to 2018-06-01

Apr 2018, May 2018, June 2018 

And what if it is between 2014-04-11 to 2018-06-01? Then the answer would be

Apr 2014, May 2014, ..., Dec 2014, Jan 2015, ..., Jan 2018, ..., June 2018

So that's why I had the following pseudo code many years ago. It merely suggested using the two months as end points and loop through them, incrementing by one month at a time. @Joshkunz mentioned he wanted the "months" and he also mentioned he wanted the "dates", without knowing exactly, it was difficult to write the exact code, but the idea is to use one simple loop to loop through the end points, and incrementing one month at a time.

The answer 8 years ago in 2010:

If adding by a week, then it will approximately do work 4.35 times the work as needed. Why not just:

1. get start date in array of integer, set it to i: [2008, 3, 12], 
       and change it to [2008, 3, 1]
2. get end date in array: [2010, 10, 26]
3. add the date to your result by parsing i
       increment the month in i
       if month is >= 13, then set it to 1, and increment the year by 1
   until either the year in i is > year in end_date, 
           or (year in i == year in end_date and month in i > month in end_date)

just pseduo code for now, haven't tested, but i think the idea along the same line will work.

Check out angular-ui, specifically, route checking: http://angular-ui.github.io/ui-utils/

Java does have StringTokenizer API and can be used for this purpose as below.

String test = "This is a test app";
int countOfTokens = new StringTokenizer(test).countTokens();
System.out.println(countOfTokens);

OR

in a single line as below

System.out.println(new StringTokenizer("This is a test app").countTokens());

StringTokenizer supports multiple spaces in the input string, counting only the words trimming unnecessary spaces.

System.out.println(new StringTokenizer("This    is    a test    app").countTokens());

Above line also prints 5

If you want to customize the configuration then use the below methodology of creating OKhttpclient first and then add builder on top of it.

private final OkHttpClient client = new OkHttpClient();

// Copy to customize OkHttp for this request.
OkHttpClient client1 = client.newBuilder()
    .readTimeout(500, TimeUnit.MILLISECONDS)
    .build();
try (Response response = client1.newCall(request).execute()) {
    System.out.println("Response 1 succeeded: " + response);
} catch (IOException e) {
    System.out.println("Response 1 failed: " + e);
}

Essentially you need to do an argsort, what implementation you need depends if you want to use external libraries (e.g. NumPy) or if you want to stay pure-Python without dependencies.

The question you need to ask yourself is: Do you want the

• indices that would sort the array/list
• indices that the elements would have in the sorted array/list

Unfortunately the example in the question doesn't make it clear what is desired because both will give the same result:

>>> arr = np.array([1, 2, 3, 100, 5])

>>> np.argsort(np.argsort(arr))
array([0, 1, 2, 4, 3], dtype=int64)

>>> np.argsort(arr)
array([0, 1, 2, 4, 3], dtype=int64)

Choosing the argsort implementation

If you have NumPy at your disposal you can simply use the function numpy.argsort or method numpy.ndarray.argsort.

An implementation without NumPy was mentioned in some other answers already, so I'll just recap the fastest solution according to the benchmark answer here

def argsort(l):
    return sorted(range(len(l)), key=l.__getitem__)

Getting the indices that would sort the array/list

To get the indices that would sort the array/list you can simply call argsort on the array or list. I'm using the NumPy versions here but the Python implementation should give the same results

>>> arr = np.array([3, 1, 2, 4])
>>> np.argsort(arr)
array([1, 2, 0, 3], dtype=int64)

The result contains the indices that are needed to get the sorted array.

Since the sorted array would be [1, 2, 3, 4] the argsorted array contains the indices of these elements in the original.

• The smallest value is 1 and it is at index 1 in the original so the first element of the result is 1.
• The 2 is at index 2 in the original so the second element of the result is 2.
• The 3 is at index 0 in the original so the third element of the result is 0.
• The largest value 4 and it is at index 3 in the original so the last element of the result is 3.

Getting the indices that the elements would have in the sorted array/list

In this case you would need to apply argsort twice:

>>> arr = np.array([3, 1, 2, 4])
>>> np.argsort(np.argsort(arr))
array([2, 0, 1, 3], dtype=int64)

In this case :

• the first element of the original is 3, which is the third largest value so it would have index 2 in the sorted array/list so the first element is 2.
• the second element of the original is 1, which is the smallest value so it would have index 0 in the sorted array/list so the second element is 0.
• the third element of the original is 2, which is the second-smallest value so it would have index 1 in the sorted array/list so the third element is 1.
• the fourth element of the original is 4 which is the largest value so it would have index 3 in the sorted array/list so the last element is 3.

Sometime you need to add proxy setting in your SDK Manager GoTO->Windows->SDK Manager->Tool->Otions There give SERVER: proxy and PORT:8080

NOTE: While my advice was true many years ago, Oracle's optimizer has improved so that the location of the where definitely no longer matters here. However preferring UNION ALL vs UNION will always be true, and portable SQL should avoid depending on optimizations that may not be in all databases.

Short answer, you want the WHERE before the UNION and you want to use UNION ALL if at all possible. If you are using UNION ALL then check the EXPLAIN output, Oracle might be smart enough to optimize the WHERE condition if it is left after.

The reason is the following. The definition of a UNION says that if there are duplicates in the two data sets, they have to be removed. Therefore there is an implicit GROUP BY in that operation, which tends to be slow. Worse yet, Oracle's optimizer (at least as of 3 years ago, and I don't think it has changed) doesn't try to push conditions through a GROUP BY (implicit or explicit). Therefore Oracle has to construct larger data sets than necessary, group them, and only then gets to filter. Thus prefiltering wherever possible is officially a Good Idea. (This is, incidentally, why it is important to put conditions in the WHERE whenever possible instead of leaving them in a HAVING clause.)

Furthermore if you happen to know that there won't be duplicates between the two data sets, then use UNION ALL. That is like UNION in that it concatenates datasets, but it doesn't try to deduplicate data. This saves an expensive grouping operation. In my experience it is quite common to be able to take advantage of this operation.

Since UNION ALL does not have an implicit GROUP BY in it, it is possible that Oracle's optimizer knows how to push conditions through it. I don't have Oracle sitting around to test, so you will need to test that yourself.

another solution is the function you can embed into your own utils.py

import time as time_ #make sure we don't override time
def millis():
    return int(round(time_.time() * 1000))

try:

overflow-wrap: break-word;

You can add a source folder to the build script and then sync. Look for sourceSets in the documentation here: http://tools.android.com/tech-docs/new-build-system/user-guide#TOC-Basic-Project

I haven't found a good way of adding test source folders. I have manually added the source to the .iml file. Of course this means it will go away everytime the build script is synched.

A good solution and without "contraptions" is the forgotten ZStack

ZStack(alignment: .top){
    Color.red
    VStack{
        Text("Hello World").font(.title)
        Text("Another").font(.body)
    }
}

Result:

GAC = Global Assembly Cache

Let's break it down:

• global - applies to the entire machine
• assembly - what .NET calls its code-libraries (DLLs)
• cache - a place to store things for faster/common access

So the GAC must be a place to store code libraries so they're accessible to all applications running on the machine.

Python's if can be used as a ternary operator:

>>> 'true' if True else 'false'
'true'
>>> 'true' if False else 'false'
'false'

You should use this

height:auto !important;

KEY and INDEX are synonyms in MySQL. They mean the same thing. In databases you would use indexes to improve the speed of data retrieval. An index is typically created on columns used in JOIN, WHERE, and ORDER BY clauses.

Imagine you have a table called users and you want to search for all the users which have the last name 'Smith'. Without an index, the database would have to go through all the records of the table: this is slow, because the more records you have in your database, the more work it has to do to find the result. On the other hand, an index will help the database skip quickly to the relevant pages where the 'Smith' records are held. This is very similar to how we, humans, go through a phone book directory to find someone by the last name: We don't start searching through the directory from cover to cover, as long we inserted the information in some order that we can use to skip quickly to the 'S' pages.

Primary keys and unique keys are similar. A primary key is a column, or a combination of columns, that can uniquely identify a row. It is a special case of unique key. A table can have at most one primary key, but more than one unique key. When you specify a unique key on a column, no two distinct rows in a table can have the same value.

Also note that columns defined as primary keys or unique keys are automatically indexed in MySQL.

If you use it on normal html tags, it means that you can programatically manipulate them in event handlers etc, eg change the href or class of an anchor tag on page load... only do that if you have to, because vanilla html tags go faster.

As far as user controls and server controls, no, they just wont work without them, without having delved into the innards of the aspx preprocessor, couldn't say exactly why, but would take a guess that for probably good reasons, they just wrote the parser that way, looking for things explicitly marked as "do something".

If @JonSkeet is around anywhere, he will probably be able to provide a much better answer.

[Test double types]

Mock vs Spy

Mock is a bare double object. This object has the same methods signatures but realisation is empty and return default value - 0 and null

Spy is a cloned double object. New object is cloned based on a real object but you have a possibility to mock it

class A {
    String foo1() {
        foo2();
        return "RealString_1";
    }

    String foo2() {
        return "RealString_2";
    }

    void foo3() { foo4(); }

    void foo4() { }
}

@Test
public void testMockA() {
    //given
    A mockA = Mockito.mock(A.class);
    Mockito.when(mockA.foo1()).thenReturn("MockedString");

    //when
    String result1 = mockA.foo1();
    String result2 = mockA.foo2();

    //then
    assertEquals("MockedString", result1);
    assertEquals(null, result2);

    //Case 2
    //when
    mockA.foo3();

    //then
    verify(mockA).foo3();
    verify(mockA, never()).foo4();
}

@Test
public void testSpyA() {
    //given
    A spyA = Mockito.spy(new A());

    Mockito.when(spyA.foo1()).thenReturn("MockedString");

    //when
    String result1 = spyA.foo1();
    String result2 = spyA.foo2();

    //then
    assertEquals("MockedString", result1);
    assertEquals("RealString_2", result2);

    //Case 2
    //when
    spyA.foo3();

    //then
    verify(spyA).foo3();
    verify(spyA).foo4();
}

In our code we have a specific validator inherited from the BaseValidator class.

This class does the following:

1. Validates the e-mail address against a regular expression.
2. Does a lookup on the MX record for the domain to make sure there is at least a server to deliver to.

This is the closest you can get to validation without actually sending the person an e-mail confirmation link.

C++ allows SFINAE to be used for this (notice that with C++11 features this is simplier because it supports extended SFINAE on nearly arbitrary expressions - the below was crafted to work with common C++03 compilers):

#define HAS_MEM_FUNC(func, name)                                        \
    template<typename T, typename Sign>                                 \
    struct name {                                                       \
        typedef char yes[1];                                            \
        typedef char no [2];                                            \
        template <typename U, U> struct type_check;                     \
        template <typename _1> static yes &chk(type_check<Sign, &_1::func > *); \
        template <typename   > static no  &chk(...);                    \
        static bool const value = sizeof(chk<T>(0)) == sizeof(yes);     \
    }

the above template and macro tries to instantiate a template, giving it a member function pointer type, and the actual member function pointer. If the types to not fit, SFINAE causes the template to be ignored. Usage like this:

HAS_MEM_FUNC(toString, has_to_string);

template<typename T> void
doSomething() {
   if(has_to_string<T, std::string(T::*)()>::value) {
      ...
   } else {
      ...
   }
}

But note that you cannot just call that toString function in that if branch. since the compiler will check for validity in both branches, that would fail for cases the function doesnt exist. One way is to use SFINAE once again (enable_if can be gotten from boost too):

template<bool C, typename T = void>
struct enable_if {
  typedef T type;
};

template<typename T>
struct enable_if<false, T> { };

HAS_MEM_FUNC(toString, has_to_string);

template<typename T> 
typename enable_if<has_to_string<T, 
                   std::string(T::*)()>::value, std::string>::type
doSomething(T * t) {
   /* something when T has toString ... */
   return t->toString();
}

template<typename T> 
typename enable_if<!has_to_string<T, 
                   std::string(T::*)()>::value, std::string>::type
doSomething(T * t) {
   /* something when T doesnt have toString ... */
   return "T::toString() does not exist.";
}

Have fun using it. The advantage of it is that it also works for overloaded member functions, and also for const member functions (remember using std::string(T::*)() const as the member function pointer type then!).

git reset HEAD^ --soft (Save your changes, back to last commit)

git reset HEAD^ --hard (Discard changes, back to last commit)

I think I got it at last by doing some manual transformations with the data before visualization:

d <- diamonds
# computing logarithm of prices
d$price <- log10(d$price)

And work out a formatter to later compute 'back' the logarithmic data:

formatBack <- function(x) 10^x 
# or with special formatter (here: "dollar")
formatBack <- function(x) paste(round(10^x, 2), "$", sep=' ') 

And draw the plot with given formatter:

m <- ggplot(d, aes(y = price, x = color))
m + geom_boxplot() + scale_y_continuous(formatter='formatBack')

Sorry to the community to bother you with a question I could have solved before! The funny part is: I was working hard to make this plot work a month ago but did not succeed. After asking here, I got it.

Anyway, thanks to @DWin for motivation!

This question has very good answer in here. My code is purely based on that answer with some modifications.

Save below snippet as wget.bat and put it in your system path (e.g. Put it in a directory and add this directory to system path.)

You can use it in your cli as follows:

wget url/to/file [?custom_name]

where url_to_file is compulsory and custom_name is optional

1. If name is not provided, then downloaded file will be saved by its own name from the url.
2. If the name is supplied, then the file will be saved by the new name.

The file url and saved filenames are displayed in ansi colored text. If that is causing problem for you, then check this github project.

@echo OFF
setLocal EnableDelayedExpansion
set Url=%1
set Url=!Url:http://=!
set Url=!Url:/=,!
set Url=!Url:%%20=?!
set Url=!Url: =?!

call :LOOP !Url!

set FileName=%2
if "%2"=="" set FileName=!FN!

echo.
echo.Downloading: [1;33m%1[0m to [1;33m\!FileName![0m

powershell.exe -Command wget %1 -OutFile !FileName!

goto :EOF
:LOOP
if "%1"=="" goto :EOF
set FN=%1
set FN=!FN:?= !
shift
goto :LOOP

P.S. This code requires you to have PowerShell installed.

While developing the application we need to define the PORT in the following way:

const port = process.env.PORT || 4000; // PORT must be in caps

And while deploying the app to server add the following method:

app.listen(port, () => {
 console.info("Server started listening.");
});

We can pass hostname as second parameter while running it in local. But while deploying it to server the hostname parameter should be removed.

app.listen(port, hostName, () => {
  console.info(`Server listening at http://${hostName}:${port}`);
});

Have a go at the below as I was struggling to

(a)Simply click on your database, select your table. Click on 'Operations'. Under the 'table options' section change the AUTO_INCREMENT value to your desired value, in this case: 10000 the click 'Go'. (See the image attached)

(b)Alternatively, you can run a SQL command under the SQL tab after selecting your table. Simply type 'ALTER TABLE table_name AUTO_INCREMENT = 10000;' then click 'Go'. That's it!! SETTING AUTO INCREMENT VALUE image(a)

It varies from assembler to assembler. Most machines offer registers, which have symbolic names like R1, or EAX (the Intel x86), and have instruction names like "CMP" for compare. And for a compare instruction, you need another operand, sometimes a register, sometimes a literal. Often assemblers allow comments to the right of instruction.

An instruction line looks like:

<opcode>   <register> <operand>   ; comment

Your assembler may vary somewhat.

For the Microsoft X86 assembler, you can write:

CMP EAX, 23 ; compare register EAX with the constant 23

or

CMP EAX, XYZ ; compare register EAX with contents of memory location named XYZ

Often one can write complex "expressions" in the operand field that enable the instruction, if it has the capability, to address memory in variety of ways. But I think this answers your question.

Tweaking MB's answer for windows, will get rid of the console window:

start javaw -jar squirrel-sql.jar

Although, this one is very old. I have come up with a solution based in this answer:

Dim ScriptEngine As ScriptControl
Set ScriptEngine = New ScriptControl
ScriptEngine.Language = "JScript"

ScriptEngine.AddCode "function encode(str) {return encodeURIComponent(str);}"
Dim encoded As String
encoded = ScriptEngine.Run("encode", "€ömE.sdfds")

Add Microsoft Script Control as reference and you are done.

Just a side note, because of the JS part, this is fully UTF-8-compatible. VB will convert correctly from UTF-16 to UTF-8.

If the table already contains data and you want to change one of the columns to identity:

First create a new table that has the same columns and specify the primary key-kolumn:

create table TempTable
(
    Id int not null identity(1, 1) primary key
    --, Other columns...
)

Then copy all rows from the original table to the new table using a standard insert-statement.

Then drop the original table.

And finally rename TempTable to whatever you want using sp_rename:

You're calling both wait and notifyAll without using a synchronized block. In both cases the calling thread must own the lock on the monitor you call the method on.

From the docs for notify (wait and notifyAll have similar documentation but refer to notify for the fullest description):

This method should only be called by a thread that is the owner of this object's monitor. A thread becomes the owner of the object's monitor in one of three ways:

• By executing a synchronized instance method of that object.
• By executing the body of a synchronized statement that synchronizes on the object.
• For objects of type Class, by executing a synchronized static method of that class.

Only one thread at a time can own an object's monitor.

Only one thread will be able to actually exit wait at a time after notifyAll as they'll all have to acquire the same monitor again - but all will have been notified, so as soon as the first one then exits the synchronized block, the next will acquire the lock etc.

We often run into this where we want to include a the index value and first and last indicators in a list without creating a new object. This allows you to know the position of the item in your list, enumeration, etc. without having to modify the existing class and then knowing whether you're at the first item in the list or the last.

foreach (Item item in this.Items
    .Select((x, i) => {
    x.ListIndex = i;
    x.IsFirst = i == 0;
    x.IsLast = i == this.Items.Count-1;
    return x;
}))

You can simply extend any class by using:

public abstract class IteratorExtender {
    public int ListIndex { get; set; }
    public bool IsFirst { get; set; } 
    public bool IsLast { get; set; } 
}

public class Item : IteratorExtender {}

This works for me on all devices [ iOS, Android and Window Mobile 8.1 ].

Does not look like the best way by any means... but cannot be more simpler :)

• Context Menu key (one one with the menu on it, next to the right Windows key)
• Then choose "Resolve" from the menu. That can be done by pressing "s".

What you can do is dynamically build the select string (the 'IN (?)' part) by a simple for loop as soon as you know how many values you need to put inside the IN clause. You can then instantiate the PreparedStatement.

You have to loop through the array and printf() each element:

for(int i=0;i<10;++i) {
  printf("%.2f ", foo[i]);
}

printf("\n");

Since in your code you used ggplot(data, fill= cond) to create the histogram you need to add the legend title by also using "fill" in the label section i.e. +labs(fill="Title name"). If you were using a different type of plot where the code was ggplot(data, colour= cond), then you could use +labs(colour= "Title Name"). In summary, the lab argument has to match the aes argument.

I have used + guides(fill=guide_legend("my awesome title")) to change the legend title on geom_bar plots but it did not seem to work for geom_point.

From my notes:

Which parses like this:

    q=latN+lonW+(label)     location of teardrop

    t=k             keyhole (satelite map)
    t=h             hybrid

    ll=lat,-lon     center of map
    spn=w.w,h.h     span of map, degrees

iwloc has something to do with the info window. hl is obviously language.

help.search() is a handy function, e.g.

> help.search("concatenate")

will lead you to paste().

Method:

• Can create file if not present
• Append to existing excel as per sheet name

import pandas as pd
from openpyxl import load_workbook

def write_to_excel(df, file):
    try:
        book = load_workbook(file)
        writer = pd.ExcelWriter(file, engine='openpyxl') 
        writer.book = book
        writer.sheets = dict((ws.title, ws) for ws in book.worksheets)
        df.to_excel(writer, **kwds)
        writer.save()
    except FileNotFoundError as e:
        df.to_excel(file, **kwds)

Usage:

df_a = pd.DataFrame(range(10), columns=["a"])
df_b = pd.DataFrame(range(10, 20), columns=["b"])
write_to_excel(df_a, "test.xlsx", sheet_name="Sheet a", columns=['a'], index=False)
write_to_excel(df_b, "test.xlsx", sheet_name="Sheet b", columns=['b'])

Using C# 7, add this extension method to any project of your solution:

public static class IDictionaryExtensions
{
    public static IEnumerable<(TKey, TValue)> Tuples<TKey, TValue>(
        this IDictionary<TKey, TValue> dict)
    {
        foreach (KeyValuePair<TKey, TValue> kvp in dict)
            yield return (kvp.Key, kvp.Value);
    }
}

And use this simple syntax

foreach (var(id, value) in dict.Tuples())
{
    // your code using 'id' and 'value'
}

Or this one, if you prefer

foreach ((string id, object value) in dict.Tuples())
{
    // your code using 'id' and 'value'
}

In place of the traditional

foreach (KeyValuePair<string, object> kvp in dict)
{
    string id = kvp.Key;
    object value = kvp.Value;

    // your code using 'id' and 'value'
}

The extension method transforms the KeyValuePair of your IDictionary<TKey, TValue> into a strongly typed tuple, allowing you to use this new comfortable syntax.

It converts -just- the required dictionary entries to tuples, so it does NOT converts the whole dictionary to tuples, so there are no performance concerns related to that.

There is a only minor cost calling the extension method for creating a tuple in comparison with using the KeyValuePair directly, which should NOT be an issue if you are assigning the KeyValuePair's properties Key and Value to new loop variables anyway.

In practice, this new syntax suits very well for most cases, except for low-level ultra-high performance scenarios, where you still have the option to simply not use it on that specific spot.

Arrays in Java have a fixed size, so you can't "add something at the end" as you could do in PHP.

A bit similar to the PHP behaviour is this:

int[] addElement(int[] org, int added) {
    int[] result = Arrays.copyOf(org, org.length +1);
    result[org.length] = added;
    return result;
}

Then you can write:

x = new int[0];
x = addElement(x, 1);
x = addElement(x, 2);

System.out.println(Arrays.toString(x));

But this scheme is horribly inefficient for larger arrays, as it makes a copy of the whole array each time. (And it is in fact not completely equivalent to PHP, since your old arrays stays the same).

The PHP arrays are in fact quite the same as a Java HashMap with an added "max key", so it would know which key to use next, and a strange iteration order (and a strange equivalence relation between Integer keys and some Strings). But for simple indexed collections, better use a List in Java, like the other answerers proposed.

If you want to avoid using List because of the overhead of wrapping every int in an Integer, consider using reimplementations of collections for primitive types, which use arrays internally, but will not do a copy on every change, only when the internal array is full (just like ArrayList). (One quickly googled example is this IntList class.)

Guava contains methods creating such wrappers in Ints.asList, Longs.asList, etc.

I'd like to propose

np.min(np.append(np.where(aa>5)[0],np.inf))

This will return the smallest index where the condition is met, while returning infinity if the condition is never met (and where returns an empty array).

The only way I know to deal with this is to create a new workspace, import projects from the polluted workspace, reconstructing all my settings (a major pain) and then delete the old workspace. Is there an easier way to deal with this?

For synchronizing or restoring all our settings we use Workspace Mechanic. Once all the settings are recorded its one click and all settings are restored... You can also setup a server which provides those settings for all users.

Imho, it is used to generate same random course result when you use random.seed(samedigit) again.

You can use jspdf to capture a canvas into an image or pdf like this:

Syntax:

SELECT <Expression>[Arithmetic_Operator]<expression>...
 FROM [Table_Name] 
 WHERE [expression];

1. Expression : Expression made up of a single constant, variable, scalar function, or column name and can also be the pieces of a SQL query that compare values against other values or perform arithmetic calculations.
2. Arithmetic_Operator : Plus(+), minus(-), multiply(*), and divide(/).
3. Table_Name : Name of the table.

I got here looking for a way to add a key/value pair(s) as a group - in my case it was the output of a function call, so adding the pair using dictionary[key] = value would require me to know the name of the key(s).

In this case, you can use the update method: dictionary.update(function_that_returns_a_dict(*args, **kwargs)))

Beware, if dictionary already contains one of the keys, the original value will be overwritten.

Try this one line code it worked for me like charm:

var data = (store.getData().getSource() || store.getData()).getRange();

I use a similar technique to what @Sarfraz posted, except instead of hiding elements, I just manipulate the class of the image that I'm loading.

<style type="text/css">
.loading { background-image: url(loading.gif); }
.loaderror { background-image: url(loaderror.gif); }
</style>
...
<img id="image" class="loading" />
...
<script type="text/javascript">
    var img = new Image();
    img.onload = function() {
        i = document.getElementById('image');
        i.removeAttribute('class');
        i.src = img.src;
    };
    img.onerror = function() {
        document.getElementById('image').setAttribute('class', 'loaderror');
    };
    img.src = 'http://path/to/image.png';
</script>

In my case, sometimes images don't load, so I handle the onerror event to change the image class so it displays an error background image (rather than the browser's broken image icon).

You can also just simply do the regular apt-get update and then, as per the manual, do:

apt-get -V upgrade

-V Show verbose version numbers

Which will show you the current package vs the one which will be upgraded in a format similar to the one bellow:

other solution:

$marray=array(....);
$options = array(
                "encoding" => "UTF-8",
                "output_type" => "xml", 
                "version" => "simple",
                "escaping" => array("non-ascii, on-print, markup")
                );
$xmlres = xmlrpc_encode_request('root', $marray, $options);
print($xmlres);

I think you pinned down quite well the difference: the framework provides a frame in which we do our work... Somehow, it is more "constraining" than a simple library.
The framework is also supposed to add consistency to a set of libraries.

Your list just contains a string. Convert it to integer IDs:

L = ['350882 348521 350166\r\n']

ids = [int(i) for i in L[0].strip().split()]
print(ids)
id = 348521
if id not in ids:
    ids.append(id)
print(ids)
id = 348522
if id not in ids:
    ids.append(id)
print(ids)
# Turn it back into your odd format
L = [' '.join(str(id) for id in ids) + '\r\n']
print(L)

Output:

[350882, 348521, 350166]
[350882, 348521, 350166]
[350882, 348521, 350166, 348522]
['350882 348521 350166 348522\r\n']

Yep, just use the trailing slash to recursively pull the directory. Works for me with Nexus 5 and current version of adb (March 2014).

The String you return here:

 return "login";

Is actually the whole content what you send back to the browser.

If you want to have the content of a file to be sent back, one way is:

1. Open file
2. Read contents into String
3. Return the value

You can go by with this answer on the question Spring boot service to download a file

By default login failed error message is nothing but a client user connection has been refused by the server due to mismatch of login credentials. First task you might check is to see whether that user has relevant privileges on that SQL Server instance and relevant database too, thats good. Obviously if the necessary prvileges are not been set then you need to fix that issue by granting relevant privileges for that user login.

Althought if that user has relevant grants on database & server if the Server encounters any credential issues for that login then it will prevent in granting the authentication back to SQL Server, the client will get the following error message:

Msg 18456, Level 14, State 1, Server <ServerName>, Line 1
Login failed for user '<Name>'

Ok now what, by looking at the error message you feel like this is non-descriptive to understand the Level & state. By default the Operating System error will show 'State' as 1 regardless of nature of the issues in authenticating the login. So to investigate further you need to look at relevant SQL Server instance error log too for more information on Severity & state of this error. You might look into a corresponding entry in log as:

2007-05-17 00:12:00.34 Logon     Error: 18456, Severity: 14, State: 8.
or

2007-05-17 00:12:00.34 Logon     Login failed for user '<user name>'.

As defined above the Severity & State columns on the error are key to find the accurate reflection for the source of the problem. On the above error number 8 for state indicates authentication failure due to password mismatch. Books online refers: By default, user-defined messages of severity lower than 19 are not sent to the Microsoft Windows application log when they occur. User-defined messages of severity lower than 19 therefore do not trigger SQL Server Agent alerts.

Sung Lee, Program Manager in SQL Server Protocols (Dev.team) has outlined further information on Error state description:The common error states and their descriptions are provided in the following table:

ERROR STATE       ERROR DESCRIPTION
------------------------------------------------------------------------------
2 and 5           Invalid userid
6                 Attempt to use a Windows login name with SQL Authentication
7                 Login disabled and password mismatch
8                 Password mismatch
9                 Invalid password
11 and 12         Valid login but server access failure
13                SQL Server service paused
18                Change password required


Well I'm not finished yet, what would you do in case of error:

2007-05-17 00:12:00.34 Logon     Login failed for user '<user name>'.

You can see there is no severity or state level defined from that SQL Server instance's error log. So the next troubleshooting option is to look at the Event Viewer's security log [edit because screen shot is missing but you get the

idea, look in the event log for interesting events].

There is no semicolon at the end of that instruction causing the error.

EDIT

Like RiverC pointed out, there is no semicolon at the end of the previous line!

require ("scripts/connect.php") 

EDIT

It seems you have no-semicolons whatsoever.

http://php.net/manual/en/language.basic-syntax.instruction-separation.php

As in C or Perl, PHP requires instructions to be terminated with a semicolon at the end of each statement.

In the case of a vector and list, the main differences that stick out to me are the following:

vector

• A vector stores its elements in contiguous memory. Therefore, random access is possible inside a vector which means that accessing an element of a vector is very fast because we can simply multiply the base address with the item index to access that element. In fact, it takes only O(1) or constant time for this purpose.

• Since a vector basically wraps an array, every time you insert an element into the vector (dynamic array), it has to resize itself by finding a new contiguous block of memory to accommodate the new elements which is time-costly.

• It does not consume extra memory to store any pointers to other elements within it.

list

• A list stores its elements in non-contiguous memory. Therefore, random access is not possible inside a list which means that to access its elements we have to use the pointers and traverse the list which is slower relative to vector. This takes O(n) or linear time which is slower than O(1).

• Since a list uses non-contiguous memory, the time taken to insert an element inside a list is a lot more efficient than in the case of its vector counterpart because reallocation of memory is avoided.

• It consumes extra memory to store pointers to the element before and after a particular element.

So, keeping these differences in mind, we usually consider memory, frequent random access and insertion to decide the winner of vector vs list in a given scenario.
