thy this:

@UiThread
    public void logMsg(final String msg) {
        new Handler(Looper.getMainLooper()).post(new Runnable() {
            @Override
            public void run() {
                Log.d("UI thread", "I am the UI thread");


            }
        });
    }

You're calling it from a worker thread. You need to call Toast.makeText() (and most other functions dealing with the UI) from within the main thread. You could use a handler, for example.

Look up Communicating with the UI Thread in the documentation. In a nutshell:

// Set this up in the UI thread.

mHandler = new Handler(Looper.getMainLooper()) {
    @Override
    public void handleMessage(Message message) {
        // This is where you do your work in the UI thread.
        // Your worker tells you in the message what to do.
    }
};

void workerThread() {
    // And this is how you call it from the worker thread:
    Message message = mHandler.obtainMessage(command, parameter);
    message.sendToTarget();
}

Other options:

You could use an AsyncTask, that works well for most things running in the background. It has hooks that you can call to indicate the progress, and when it's done.

You could also use Activity.runOnUiThread().

 DateTime.Today.ToString("MM/dd/yy")

Look at the docs for custom date and time format strings for more info.

(Oh, and I hope this app isn't destined for other cultures. That format could really confuse a lot of people... I've never understood the whole month/day/year thing, to be honest. It just seems weird to go "middle/low/high" in terms of scale like that.)

It sounds to me like you want to be able to easily pass a string created using printf-style formatting to the function you already have that takes a simple string. You can create a wrapper function using stdarg.h facilities and vsnprintf() (which may not be readily available, depending on your compiler/platform):

#include <stdarg.h>
#include <stdio.h>

// a function that accepts a string:

void foo( char* s);

// You'd like to call a function that takes a format string 
//  and then calls foo():

void foofmt( char* fmt, ...)
{
    char buf[100];     // this should really be sized appropriately
                       // possibly in response to a call to vsnprintf()
    va_list vl;
    va_start(vl, fmt);

    vsnprintf( buf, sizeof( buf), fmt, vl);

    va_end( vl);

    foo( buf);
}



int main()
{
    int val = 42;

    foofmt( "Some value: %d\n", val);
    return 0;
}

For platforms that don't provide a good implementation (or any implementation) of the snprintf() family of routines, I've successfully used a nearly public domain snprintf() from Holger Weiss.

I think that the following example demonstrates what you need:http://www.hacksparrow.com/base64-encoding-decoding-in-node-js.html

The essence of the article is this code part:

var fs = require('fs');

// function to encode file data to base64 encoded string
function base64_encode(file) {
    // read binary data
    var bitmap = fs.readFileSync(file);
    // convert binary data to base64 encoded string
    return new Buffer(bitmap).toString('base64');
}

// function to create file from base64 encoded string
function base64_decode(base64str, file) {
    // create buffer object from base64 encoded string, it is important to tell the constructor that the string is base64 encoded
    var bitmap = new Buffer(base64str, 'base64');
    // write buffer to file
    fs.writeFileSync(file, bitmap);
    console.log('******** File created from base64 encoded string ********');
}

// convert image to base64 encoded string
var base64str = base64_encode('kitten.jpg');
console.log(base64str);
// convert base64 string back to image 
base64_decode(base64str, 'copy.jpg');

You need to use get to obtain the value rather than the character name of the object as returned by ls:

x <- 1L
typeof(ls())
[1] "character"
typeof(get(ls()))
[1] "integer"

Alternatively, for the problem as presented you might want to use eapply:

eapply(.GlobalEnv,typeof)
$x
[1] "integer"

$a
[1] "double"

$b
[1] "character"

$c
[1] "list"

You should be able to do the count on the purch variable:

purch.Count();

e.g.

var purch = from purchase in myBlaContext.purchases
select purchase;

purch.Count();

s=s.replaceAll("[*a-zA-Z]", "") replaces all alphabets

s=s.replaceAll("[*0-9]", "") replaces all numerics

if you do above two replaces you will get all special charactered string

If you want to extract only integers from a String s=s.replaceAll("[^0-9]", "")

If you want to extract only Alphabets from a String s=s.replaceAll("[^a-zA-Z]", "")

Happy coding :)

If you want to build Java EE applications, it's best to use Eclipse IDE for Java EE. It has editors from HTML to JSP/JSF, Javascript. It's rich for webapps development, and provide plugins and tools to develop Java EE applications easily (all bundled).

Eclipse Classic is basically the full featured Eclipse without the Java EE part.

Here is more clear concepts about firebase message. I found it from their support team.

Firebase has three message types:

Notification messages : Notification message works on background or foreground. When app is in background, Notification messages are delivered to the system tray. If the app is in the foreground, messages are handled by onMessageReceived() or didReceiveRemoteNotification callbacks. These are essentially what is referred to as Display messages.

Data messages: On Android platform, data message can work on background and foreground. The data message will be handled by onMessageReceived(). A platform specific note here would be: On Android, the data payload can be retrieved in the Intent used to launch your activity. To elaborate, if you have "click_action":"launch_Activity_1", you can retrieve this intent through getIntent() from only Activity_1.

Messages with both notification and data payloads: When in the background, apps receive the notification payload in the notification tray, and only handle the data payload when the user taps on the notification. When in the foreground, your app receives a message object with both payloads available. Secondly, the click_action parameter is often used in notification payload and not in data payload. If used inside data payload, this parameter would be treated as custom key-value pair and therefore you would need to implement custom logic for it to work as intended.

Also, I recommend you to use onMessageReceived method (see Data message) to extract the data bundle. From your logic, I checked the bundle object and haven't found expected data content. Here is a reference to a similar case which might provide more clarity.

You want to check a couple of things; if this is your own jar file, make sure you have defined a Main-class in the manifest. Since we know you can run it from the command line, the other thing to do is create a windows shortcut, and modify the properties (you'll have to look around, I don't have a Windows machine to look at) so that the command it executes on open is the java -jar command you mentioned.

The other thing: if something isn't confused, it should work anyway; check and make sure you have java associated with the .jar extension.

In TypeScript 1.6, user-defined type guard will do the job.

interface Foo {
    fooProperty: string;
}

interface Bar {
    barProperty: string;
}

function isFoo(object: any): object is Foo {
    return 'fooProperty' in object;
}

let object: Foo | Bar;

if (isFoo(object)) {
    // `object` has type `Foo`.
    object.fooProperty;
} else {
    // `object` has type `Bar`.
    object.barProperty;
}

And just as Joe Yang mentioned: since TypeScript 2.0, you can even take the advantage of tagged union type.

interface Foo {
    type: 'foo';
    fooProperty: string;
}

interface Bar {
    type: 'bar';
    barProperty: number;
}

let object: Foo | Bar;

// You will see errors if `strictNullChecks` is enabled.
if (object.type === 'foo') {
    // object has type `Foo`.
    object.fooProperty;
} else {
    // object has type `Bar`.
    object.barProperty;
}

And it works with switch too.

Using imgscalr – Java Image Scaling Library:

BufferedImage image =
     Scalr.resize(originalImage, Scalr.Method.BALANCED, newWidth, newHeight);

This is fast enough for me.

Strings are immutable types. You cannot modify them, only return new string instances.

Because of that, formatting with an instance method makes little sense, as it would have to be called like:

String formatted = "%s: %s".format(key, value);

The original Java authors (and .NET authors) decided that a static method made more sense in this situation, as you are not modifying the target, but instead calling a format method and passing in an input string.

Here is an example of why format() would be dumb as an instance method. In .NET (and probably in Java), Replace() is an instance method.

You can do this:

 "I Like Wine".Replace("Wine","Beer");

However, nothing happens, because strings are immutable. Replace() tries to return a new string, but it is assigned to nothing.

This causes lots of common rookie mistakes like:

inputText.Replace(" ", "%20");

Again, nothing happens, instead you have to do:

inputText = inputText.Replace(" ","%20");

Now, if you understand that strings are immutable, that makes perfect sense. If you don't, then you are just confused. The proper place for Replace() would be where format() is, as a static method of String:

 inputText = String.Replace(inputText, " ", "%20");

Now there is no question as to what's going on.

The real question is, why did the authors of these frameworks decide that one should be an instance method, and the other static? In my opinion, both are more elegantly expressed as static methods.

Regardless of your opinion, the truth is that you are less prone to make a mistake using the static version, and the code is easier to understand (No Hidden Gotchas).

Of course there are some methods that are perfect as instance methods, take String.Length()

int length = "123".Length();

In this situation, it's obvious we are not trying to modify "123", we are just inspecting it, and returning its length. This is a perfect candidate for an instance method.

My simple rules for Instance Methods on Immutable Objects:

• If you need to return a new instance of the same type, use a static method.
• Otherwise, use an instance method.

Make sure that both projects have same target framework version here: right click on project -> properties -> application (tab) -> target framework

Also, make sure that the project "logger" (which you want to include in the main project) has the output type "Class Library" in: right click on project -> properties -> application (tab) -> output type

Finally, Rebuild the solution.

You need geopy

pip install geopy

and then:

from geopy.geocoders import Nominatim
geolocator = Nominatim()
location = geolocator.reverse("48.8588443, 2.2943506")

print(location.address)

to get more information:

print (location.raw)

Walkthrough on using MySQL's LOAD DATA command:

1. Create your table:

   CREATE TABLE foo(myid INT, mymessage VARCHAR(255), mydecimal DECIMAL(8,4));
   

2. Create your tab delimited file (note there are tabs between the columns):

   1   Heart disease kills     1.2
   2   one out of every two    2.3
   3   people in America.      4.5
   

3. Use the load data command:

   LOAD DATA LOCAL INFILE '/tmp/foo.txt' 
   INTO TABLE foo COLUMNS TERMINATED BY '\t';
   

   If you get a warning that this command can't be run, then you have to enable the --local-infile=1 parameter described here: How can I correct MySQL Load Error

4. The rows get inserted:

   Query OK, 3 rows affected (0.00 sec)
   Records: 3  Deleted: 0  Skipped: 0  Warnings: 0
   

5. Check if it worked:

   mysql> select * from foo;
   +------+----------------------+-----------+
   | myid | mymessage            | mydecimal |
   +------+----------------------+-----------+
   |    1 | Heart disease kills  |    1.2000 |
   |    2 | one out of every two |    2.3000 |
   |    3 | people in America.   |    4.5000 |
   +------+----------------------+-----------+
   3 rows in set (0.00 sec)
   

How to specify which columns to load your text file columns into:

Like this:

LOAD DATA LOCAL INFILE '/tmp/foo.txt' INTO TABLE foo
FIELDS TERMINATED BY '\t' LINES TERMINATED BY '\n'
(@col1,@col2,@col3) set myid=@col1,mydecimal=@col3;

The file contents get put into variables @col1, @col2, @col3. myid gets column 1, and mydecimal gets column 3. If this were run, it would omit the second row:

mysql> select * from foo;
+------+-----------+-----------+
| myid | mymessage | mydecimal |
+------+-----------+-----------+
|    1 | NULL      |    1.2000 |
|    2 | NULL      |    2.3000 |
|    3 | NULL      |    4.5000 |
+------+-----------+-----------+
3 rows in set (0.00 sec)

If you truly wish to use PHP, you could use

include "file.php";

or

require "file.php";

and then in file.php, use a heredoc & echo it in.

file.php contents:
$some_js_code <<<_code
function myFunction()
{
   Alert("Some JS code would go here.");
}
_code;

At the top of your PHP file, bring in the file using either include or require then in head (or body section) echo it in

<?php
require "file.php";
?>
<html>
<head>
<?php
echo $some_js_code;
?>
</script>
</head>
<body>
</body>
</html>

Different way but it works. Just my $.02...

Two points:

1. Check your inputs. I can't imagine a situation where you'd get 2 hours by subtracting the time values you're talking about. If I do this:

       DateTime startTime = Convert.ToDateTime("7:00 AM");
       DateTime endtime = Convert.ToDateTime("2:00 PM");
       TimeSpan duration = startTime - endtime;
   

   ... I get -07:00:00 as the result. And even if I forget to provide the AM/PM value:

       DateTime startTime = Convert.ToDateTime("7:00");
       DateTime endtime = Convert.ToDateTime("2:00");
       TimeSpan duration = startTime - endtime;
   

   ... I get 05:00:00. So either your inputs don't contain the values you have listed or you are in a machine environment where they are begin parsed in an unexpected way. Or you're not actually getting the results you are reporting.

2. To find the difference between a start and end time, you need to do endTime - startTime, not the other way around.

The easiest way to update versions IMO:

$ mvn versions:set -DgenerateBackupPoms=false

(do that in your root/parent pom folder).

Your POMs are parsed and you're asked which version to set.

I had this same notice appear after making some changes. It turned out to be because I had changed between a single $http request to multiple requests using angularjs $q service.

I hadn't wrapped them in an array. e.g.

$q.all(request1, request2).then(...) 

rather than

$q.all([request1, request2]).then(...)

I hope this might save somebody some time.

If you know the number of levels in nested arrays you can simply do nested loops. Like so:

//  Scan through outer loop
foreach ($tmpArray as $innerArray) {
    //  Check type
    if (is_array($innerArray)){
        //  Scan through inner loop
        foreach ($innerArray as $value) {
            echo $value;
        }
    }else{
        // one, two, three
        echo $innerArray;
    }
}

if you do not know the depth of array you need to use recursion. See example below:

//  Multi-dementional Source Array
$tmpArray = array(
    array("one", array(1, 2, 3)),
    array("two", array(4, 5, 6)),
    array("three", array(
            7,
            8,
            array("four", 9, 10)
    ))
);

//  Output array
displayArrayRecursively($tmpArray);

/**
 * Recursive function to display members of array with indentation
 *
 * @param array $arr Array to process
 * @param string $indent indentation string
 */
function displayArrayRecursively($arr, $indent='') {
    if ($arr) {
        foreach ($arr as $value) {
            if (is_array($value)) {
                //
                displayArrayRecursively($value, $indent . '--');
            } else {
                //  Output
                echo "$indent $value \n";
            }
        }
    }
}

The code below with display only nested array with values for your specific case (3rd level only)

$tmpArray = array(
    array("one", array(1, 2, 3)),
    array("two", array(4, 5, 6)),
    array("three", array(7, 8, 9))
);

//  Scan through outer loop
foreach ($tmpArray as $inner) {

    //  Check type
    if (is_array($inner)) {
        //  Scan through inner loop
        foreach ($inner[1] as $value) {
           echo "$value \n";
        }
    }
}

Here's an example of how to create a ColorList programmatically in Kotlin:

val colorList = ColorStateList(
        arrayOf(
                intArrayOf(-android.R.attr.state_enabled),  // Disabled
                intArrayOf(android.R.attr.state_enabled)    // Enabled
        ),
        intArrayOf(
                Color.BLACK,     // The color for the Disabled state
                Color.RED        // The color for the Enabled state
        )
)

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

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

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

Fiddle: http://sqlfiddle.com/#!2/a4f92/1

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

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

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

});?

Probably embed into your objects an ID "tag" and use it to distinguish between objects of class A and objects of class B.

This however shows a flaw in the design. Ideally those methods in B which A doesn't have, should be part of A but left empty, and B overwrites them. This does away with the class-specific code and is more in the spirit of OOP.

Simply set location relative to null after calling pack on the JFrame, that's it.

e.g.,

  JFrame frame = new JFrame("FooRendererTest");
  frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  frame.getContentPane().add(mainPanel); // or whatever...
  frame.pack();
  frame.setLocationRelativeTo(null);  // *** this will center your app ***
  frame.setVisible(true);

As others have said, CGFloat is a float on 32-bit systems and a double on 64-bit systems. However, the decision to do that was inherited from OS X, where it was made based on the performance characteristics of early PowerPC CPUs. In other words, you should not think that float is for 32-bit CPUs and double is for 64-bit CPUs. (I believe, Apple's ARM processors were able to process doubles long before they went 64-bit.) The main performance hit of using doubles is that they use twice the memory and therefore might be slower if you are doing a lot of floating point operations.

Another difference between them is the size of the file:

• Mustache.js has 9kb,
• Handlebars.js has 86kb, or 18kb if using precompiled templates.

To see the performance benefits of Handlebars.js we must use precompiled templates.

As already answered, the C standards have no way to directly write binary numbers. There are compiler extensions, however, and apparently C++14 includes the 0b prefix for binary. (Note that this answer was originally posted in 2010.)

One popular workaround is to include a header file with helper macros. One easy option is also to generate a file that includes macro definitions for all 8-bit patterns, e.g.:

#define B00000000 0
#define B00000001 1
#define B00000010 2
…

This results in only 256 #defines, and if larger than 8-bit binary constants are needed, these definitions can be combined with shifts and ORs, possibly with helper macros (e.g., BIN16(B00000001,B00001010)). (Having individual macros for every 16-bit, let alone 32-bit, value is not plausible.)

Of course the downside is that this syntax requires writing all the leading zeroes, but this may also make it clearer for uses like setting bit flags and contents of hardware registers. For a function-like macro resulting in a syntax without this property, see bithacks.h linked above.

question is not clear, but what i understand you need to select a catagory that has name attribute and should have child author with value specified , correct me if i am worng

here is a xpath

//category[@name='Required value'][./author[contains(.,'Required value')]]
e.g
//category[@name='Sport'][./author[contains(.,'James Small')]]

I've recently found that blanks in the name of the redirect file will cause the "ambiguous redirect" message.

For example if you redirect to application$(date +%Y%m%d%k%M%S).log and you specify the wrong formatting characters, the redirect will fail before 10 AM for example. If however, you used application$(date +%Y%m%d%H%M%S).log it would succeed. This is because the %k format yields ' 9' for 9AM where %H yields '09' for 9AM.

echo $(date +%Y%m%d%k%M%S) gives 20140626 95138

echo $(date +%Y%m%d%H%M%S) gives 20140626095138

The erroneous date might give something like:

echo "a" > myapp20140626 95138.log

where the following is what would be desired:

echo "a" > myapp20140626095138.log

Those look much like Bonjour / mDNS requests to me. Those packets use multicast IP address 224.0.0.251 and port 5353.

The most likely source for this is Apple iTunes, which comes pre-installed on Mac computers (and is a popular install on Windows machines as well). Apple iTunes uses it to discover other iTunes-compatible devices in the same WiFi network.

mDNS is also used (primarily by Apple's Mac and iOS devices) to discover mDNS-compatible devices such as printers on the same network.

If this is a Linux box instead, it's probably the Avahi daemon then. Avahi is ZeroConf/Bonjour compatible and installed by default, but if you don't use DNS-SD or mDNS, it can be disabled.

Remove existing origin and add new origin to your project directory

>$ git push origin master

Here's another sample using JQuery 1.10.2

$(".chkcc9").on('click', function() {
            $(this)
            .parents('table')
            .find('.group1') 
            .prop('checked', $(this).is(':checked')); 
});

A more elegant way is to assign the whole array at once:

Sub PrintArray(Data, SheetName, StartRow, StartCol)

    Dim Rng As Range

    With Sheets(SheetName)
        Set Rng = .Range(.Cells(StartRow, StartCol), _
            .Cells(UBound(Data, 1) - LBound(Data, 1) + StartRow, _
            UBound(Data, 2) - LBound(Data, 2) + StartCol))
    End With
    Rng.Value2 = Data

End Sub

But watch out: it only works up to a size of about 8,000 cells. Then Excel throws a strange error. The maximum size isn't fixed and differs very much from Excel installation to Excel installation.

Generate pseudo random numbers between 1 and an [UPPER_LIMIT]

You can use the following to generate a number between 1 and an upper limit.

Math.abs(new Random().nextInt() % [UPPER_LIMIT]) + 1

Here is a specific example:

Example - Generate pseudo random numbers in the range 1 to 600:

Math.abs(new Random().nextInt() % 600) + 1

This will generate a random number within a range for you. In this case 1-600. You can change the value 600 to anything you need in the range of integers.

Generate pseudo random numbers between a [LOWER_LIMIT] and an [UPPER_LIMIT]

If you want to use a lower bound that is not equal to 1 then you can use the following formula.

Math.abs(new Random().nextInt() % ([UPPER_LIMIT] - [LOWER_LIMIT])) + [LOWER_LIMIT]

Here is a specific example:

Example - Generate pseudo random numbers in the range of 40 to 99:

Math.abs( new Random().nextInt() % (99 - 40) ) + 40

This will generate a random number within a range of 40 and 99.

I can show you how I used it

  function GetDenierValue() {
        var denierid = $("#productDenierid").val() == '' ? 0 : $("#productDenierid").val();
        var param = { 'productDenierid': denierid };
        $.ajax({
            url: "/Admin/ProductComposition/GetDenierValue",
            dataType: "json",
            contentType: "application/json;charset=utf-8",
            type: "POST",
            data: JSON.stringify(param),
            success: function (msg) {
                if (msg != null) {
                    return msg.URL;
                }
            }
        });
    }

On a Windows 8.1 machine I got Send-MailMessage to send an email with an attachment through Gmail using the following script:

$EmFrom = "[email protected]"
$username = "[email protected]"
$pwd = "YOURPASSWORD"
$EmTo = "[email protected]"
$Server = "smtp.gmail.com"
$port = 587
$Subj = "Test"
$Bod = "Test 123"
$Att = "c:\Filename.FileType"
$securepwd = ConvertTo-SecureString $pwd -AsPlainText -Force
$cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $username, $securepwd
Send-MailMessage -To $EmTo -From $EmFrom -Body $Bod -Subject $Subj -Attachments $Att -SmtpServer $Server -port $port -UseSsl  -Credential $cred

Me also got the same issue.

In my case i already registerd with my free account. We can't delete that app bundle id from our free account.

So i changed bundle id not app name and again i tried it's working.

just use the core https module with the https.request function. Example for a POST request (GET would be similar):

var https = require('https');

var options = {
  host: 'www.google.com',
  port: 443,
  path: '/upload',
  method: 'POST'
};

var req = https.request(options, function(res) {
  console.log('STATUS: ' + res.statusCode);
  console.log('HEADERS: ' + JSON.stringify(res.headers));
  res.setEncoding('utf8');
  res.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
  });
});

req.on('error', function(e) {
  console.log('problem with request: ' + e.message);
});

// write data to request body
req.write('data\n');
req.write('data\n');
req.end();

I too had OpenJDK on my Ubuntu machine:

$ java -version
java version "1.7.0_51"
OpenJDK Runtime Environment (IcedTea 2.4.4) (7u51-2.4.4-0ubuntu0.13.04.2)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)

Replacing OpenJDK with the HotSpot VM works fine:

sudo apt-get autoremove openjdk-7-jre-headless

There is no such functionality in jQuery. Use JSON.stringify or alternatively any jQuery plugin with similar functionality (e.g jquery-json).

 mvn --projects A,B,F --also-make clean install

OR

mvn -pl A,B,F -am clean install

OR

mvn -pl A,B,F -amd clean install

Note: When you specify a project with the -am option, Maven will build all of the projects that the specified project depends upon (either directly or indirectly). Maven will examine the list of projects and walk down the dependency tree, finding all of the projects that it needs to build.

While the -am command makes all of the projects required by a particular project in a multi-module build, the -amd or --also-make-dependents option configures Maven to build a project and any project that depends on that project. When using --also-make-dependents, Maven will examine all of the projects in our reactor to find projects that depend on a particular project. It will automatically build those projects and nothing else.

Tomcat-7 JNDI configuration:

Steps:

1. Open the server.xml in the tomcat-dir/conf
2. Add below <Resource> tag with your DB details inside <GlobalNamingResources>

<Resource name="jdbc/mydb"
          global="jdbc/mydb"
          auth="Container"
          type="javax.sql.DataSource"
          driverClassName="com.mysql.jdbc.Driver"
          url="jdbc:mysql://localhost:3306/test"
          username="root"
          password=""
          maxActive="10"
          maxIdle="10"
          minIdle="5"
          maxWait="10000"/>

3. Save the server.xml file
4. Open the context.xml in the tomcat-dir/conf
5. Add the below <ResourceLink> inside the <Context> tag.

<ResourceLink name="jdbc/mydb" 
              global="jdbc/mydb"
              auth="Container"
              type="javax.sql.DataSource" />

6. Save the context.xml
7. Open the hibernate-cfg.xml file and add and remove below properties.

Adding:
-------
<property name="connection.datasource">java:comp/env/jdbc/mydb</property>

Removing:
--------
<!--<property name="connection.url">jdbc:mysql://localhost:3306/mydb</property> -->
<!--<property name="connection.username">root</property> -->
<!--<property name="connection.password"></property> -->

8. Save the file and put latest .WAR file in tomcat.
9. Restart the tomcat. the DB connection will work.

I thought it should be

std::transform( map.begin(), map.end(), 
                   std::back_inserter(vec), 
                   boost::bind(&MapT::value_type::first,_1) ); 

Try this:

 DatePicker datePicker = (DatePicker) findViewById(R.id.datePicker1);
 int day = datePicker.getDayOfMonth();
 int month = datePicker.getMonth() + 1;
 int year = datePicker.getYear();

If the top answers don't work, look for a config named PrecompiledApp.config in the hosting directory and delete it if it exists. This file prevents IISExpress and LocalIIS to work properly. (And I think that's a bug) The content of the file in my case was:

<precompiledApp version="2" updatable="true"/>

And I'm 100% positive that was the problem with my case since I tried everything in 2 hours and tested lots of times with this config.

One more thing: You cannot use aspnet_regiis in newer versions of Windows and IIS so try

dism /online /enable-feature /featurename:IIS-ASPNET45 /all

On Swift 3. You can create an extension and add after your view class.

extension UITextField
{
    func setBottomBorder(borderColor: UIColor)
    {

        self.borderStyle = UITextBorderStyle.none
        self.backgroundColor = UIColor.clear
        let width = 1.0

        let borderLine = UIView()
        borderLine.frame = CGRect(x: 0, y: Double(self.frame.height) - width, width: Double(self.frame.width), height: width)

        borderLine.backgroundColor = borderColor
        self.addSubview(borderLine)
    }
}

How to change your global broadcast to LocalBroadcast

1) Create Instance

LocalBroadcastManager localBroadcastManager = LocalBroadcastManager.getInstance(this);

2) For registering BroadcastReceiver

Replace

registerReceiver(new YourReceiver(),new IntentFilter("YourAction"));

With

localBroadcastManager.registerReceiver(new YourReceiver(),new IntentFilter("YourAction"));

3) For sending broadcast message

Replace

sendBroadcast(intent);

With

localBroadcastManager.sendBroadcast(intent);

4) For unregistering broadcast message

Replace

unregisterReceiver(mybroadcast);

With

localBroadcastManager.unregisterReceiver(mybroadcast);

This has worked for me.

created() {
            EventBus.$on('refresh-stores-list', () => {
                this.$forceUpdate();
            });
        },

The other component fires the refresh-stores-list event will cause the current component to rerender

Remove the extension altogether and then double-click it. Most system shell scripts are like this. As long as it has a shebang it will work.

Configure your repository using git config. For example:

git config --add --local core.sshCommand 'ssh -i ~/.ssh/<<<PATH_TO_SSH_KEY>>>'

For Python 3:

import collections.abc

if isinstance(obj, collections.abc.Sequence) and not isinstance(obj, str):
    print("obj is a sequence (list, tuple, etc) but not a string")

Changed in version 3.3: Moved Collections Abstract Base Classes to the collections.abc module. For backwards compatibility, they will continue to be visible in this module as well until version 3.8 where it will stop working.

For Python 2:

import collections

if isinstance(obj, collections.Sequence) and not isinstance(obj, basestring):
    print "obj is a sequence (list, tuple, etc) but not a string or unicode"

It calculates e^x for each x in your list where e is Euler's number (approximately 2.718). In other words, np.exp(range(5)) is similar to [math.e**x for x in range(5)].

You should use PDO Prepare

From the link:

Calling PDO::prepare() and PDOStatement::execute() for statements that will be issued multiple times with different parameter values optimizes the performance of your application by allowing the driver to negotiate client and/or server side caching of the query plan and meta information, and helps to prevent SQL injection attacks by eliminating the need to manually quote the parameters.

This should work

$root = realpath($_SERVER["DOCUMENT_ROOT"]);

include "$root/inc/include1.php";

In java you don't check if a key is pressed, instead you listen to KeyEvents. The right way to achieve your goal is to register a KeyEventDispatcher, and implement it to maintain the state of the desired key:

import java.awt.KeyEventDispatcher;
import java.awt.KeyboardFocusManager;
import java.awt.event.KeyEvent;

public class IsKeyPressed {
    private static volatile boolean wPressed = false;
    public static boolean isWPressed() {
        synchronized (IsKeyPressed.class) {
            return wPressed;
        }
    }

    public static void main(String[] args) {
        KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(new KeyEventDispatcher() {

            @Override
            public boolean dispatchKeyEvent(KeyEvent ke) {
                synchronized (IsKeyPressed.class) {
                    switch (ke.getID()) {
                    case KeyEvent.KEY_PRESSED:
                        if (ke.getKeyCode() == KeyEvent.VK_W) {
                            wPressed = true;
                        }
                        break;

                    case KeyEvent.KEY_RELEASED:
                        if (ke.getKeyCode() == KeyEvent.VK_W) {
                            wPressed = false;
                        }
                        break;
                    }
                    return false;
                }
            }
        });
    }
}

Then you can always use:

if (IsKeyPressed.isWPressed()) {
    // do your thing.
}

You can, of course, use same method to implement isPressing("<some key>") with a map of keys and their state wrapped inside IsKeyPressed.

OK, this approach will only be useful when you are connecting to a real device rather than to an Android emulator.

Resetting the DDMS ADB connection timeout won't work nicely with a real device when there is a problem with USB debugging mode of the device.

So, disabling and re-enabling USB debugging mode seems to resolve the issue by creating a new fresh ADB session on the device.

I would use the operator[].

map <char, int> m1;

m1['G'] ++;  // If the element 'G' does not exist then it is created and 
             // initialized to zero. A reference to the internal value
             // is returned. so that the ++ operator can be applied.

// If 'G' did not exist it now exist and is 1.
// If 'G' had a value of 'n' it now has a value of 'n+1'

So using this technique it becomes really easy to read all the character from a stream and count them:

map <char, int>                m1;
std::ifstream                  file("Plop");
std::istreambuf_iterator<char> end;

for(std::istreambuf_iterator<char> loop(file); loop != end; ++loop)
{
    ++m1[*loop]; // prefer prefix increment out of habbit
}

In C++ you are supposed to declare functions before you can use them. In your code integrate is not declared before the point of the first call to integrate. The same applies to sum. Hence the error. Either reorder your definitions so that function definition precedes the first call to that function, or introduce a [forward] non-defining declaration for each function.

Additionally, defining external non-inline functions in header files in a no-no in C++. Your definitions of SkewNormalEvalutatable::SkewNormalEvalutatable, getSkewNormal, integrate etc. have no business being in header file.

Also SkewNormalEvalutatable e(); declaration in C++ declares a function e, not an object e as you seem to assume. The simple SkewNormalEvalutatable e; will declare an object initialized by default constructor.

Also, you receive the last parameter of integrate (and of sum) by value as an object of Evaluatable type. That means that attempting to pass SkewNormalEvalutatable as last argument of integrate will result in SkewNormalEvalutatable getting sliced to Evaluatable. Polymorphism won't work because of that. If you want polymorphic behavior, you have to receive this parameter by reference or by pointer, but not by value.

Also, make sure you undo the migration you made either by rollback or to a particular version.

Reason #1

There was a point where buggy/lazy implementations of HTML/XHTML renderers were more common than those that got it right. Many years ago, I regularly encountered rendering problems in mainstream browsers resulting from the use of unencoded quote chars in regular text content of HTML/XHTML documents. Though the HTML spec has never disallowed use of these chars in text content, it became fairly standard practice to encode them anyway, so that non-spec-compliant browsers and other processors would handle them more gracefully. As a result, many "old-timers" may still do this reflexively. It is not incorrect, though it is now probably unnecessary, unless you're targeting some very archaic platforms.

Reason #2

When HTML content is generated dynamically, for example, by populating an HTML template with simple string values from a database, it's necessary to encode each value before embedding it in the generated content. Some common server-side languages provided a single function for this purpose, which simply encoded all chars that might be invalid in some context within an HTML document. Notably, PHP's htmlspecialchars() function is one such example. Though there are optional arguments to htmlspecialchars() that will cause it to ignore quotes, those arguments were (and are) rarely used by authors of basic template-driven systems. The result is that all "special chars" are encoded everywhere they occur in the generated HTML, without regard for the context in which they occur. Again, this is not incorrect, it's simply unnecessary.

I had this problem in a program I wrote a year ago -- turns out the answer is rather complicated. You'll need to use nohup as well as output redirection, as explained in the wikipedia artcle on nohup, copied here for your convenience.

Nohuping backgrounded jobs is for example useful when logged in via SSH, since backgrounded jobs can cause the shell to hang on logout due to a race condition [2]. This problem can also be overcome by redirecting all three I/O streams:

nohup myprogram > foo.out 2> foo.err < /dev/null &

The best solution:-

angular.module("myapp").controller("frstCtrl",function($scope){
    $scope.name="Atul Singh";
})
.controller("secondCtrl",function($scope){
     angular.extend(this, $controller('frstCtrl', {$scope:$scope}));
     console.log($scope);
})

// Here you got the first controller call without executing it

If you're executing this through PHP, what about this?

$hQuery = mysql_query("SELECT * FROM users");
while($hRow = mysql_fetch_array($hQuery)) {
    $hOut .= $hRow['username'] . ", ";
}
$hOut = substr($hOut, 0, strlen($hOut) - 1);
echo $hOut;

Time. .Now includes the 09:23:12 or whatever; .Today is the date-part only (at 00:00:00 on that day).

So use .Now if you want to include the time, and .Today if you just want the date!

.Today is essentially the same as .Now.Date

To add the CORS authorization to the header using Apache, simply add the following line inside either the <Directory>, <Location>, <Files> or <VirtualHost> sections of your server config (usually located in a *.conf file, such as httpd.conf or apache.conf), or within a .htaccess file:

Header set Access-Control-Allow-Origin "*"

And then restart apache.

Altering headers requires the use of mod_headers. Mod_headers is enabled by default in Apache, however, you may want to ensure it's enabled.

Use

SELECT length(yourfield) FROM table;

In Windows Server LDAP is a protocol which is used for access Active Directory object, user authentication, authorization.

To remove everything before a certain character, use a regular expression:

re.sub(r'^[^a]*', '')

to remove everything up to the first 'a'. [^a] can be replaced with any character class you like, such as word characters.

Old question, but another "pure razor" answer would be:

@Html.CheckBoxFor(model => model.As, htmlAttributes: new { @checked = true} )

Use array_walk_recursive function for multi-denominational array.

array_walk_recursive($data, function (&$v, $k) { 
    if($k == 'transaction_date'){ 
        $v = date('d/m/Y',$v); 
    } 
});

Vivaldi Chromium-based Browser can hide the address bar for my Home Theather PC. Using that app you can show/hide a floating bar with F8 key. Other answers are unrelated to what was asked!

SQLite has limited ALTER TABLE support that you can use to add a column to the end of a table or to change the name of a table.

If you want to make more complex changes in the structure of a table, you will have to recreate the table. You can save existing data to a temporary table, drop the old table, create the new table, then copy the data back in from the temporary table.

For example, suppose you have a table named "t1" with columns names "a" and "c" and that you want to insert column "b" from this table. The following steps illustrate how this could be done:

BEGIN TRANSACTION;
CREATE TEMPORARY TABLE t1_backup(a,c);
INSERT INTO t1_backup SELECT a,c FROM t1;
DROP TABLE t1;
CREATE TABLE t1(a,b, c);
INSERT INTO t1 SELECT a,c FROM t1_backup;
DROP TABLE t1_backup;
COMMIT;

Now you are ready to insert your new data like so:

UPDATE t1 SET b='blah' WHERE a='key'

Static memory allocation is allocated memory before execution pf program during compile time. Dynamic memory alocation is alocated memory during execution of program at run time.

• A leading slash tells the browser to start at the root directory.
• If you don't have the leading slash, you're referencing from the current directory.
• If you add two dots before the leading slash, it means you're referencing the parent of the current directory.

Take the following folder structure

notice:

• the ROOT checkmark is green,
• the second checkmark is orange,
• the third checkmark is purple,
• the forth checkmark is yellow

Now in the index.html.en file you'll want to put the following markup

<p>
    <span>src="check_mark.png"</span>
    <img src="check_mark.png" />
    <span>I'm purple because I'm referenced from this current directory</span>
</p>

<p>
    <span>src="/check_mark.png"</span>
    <img src="/check_mark.png" />
    <span>I'm green because I'm referenced from the ROOT directory</span>
</p>

<p>
    <span>src="subfolder/check_mark.png"</span>
    <img src="subfolder/check_mark.png" />
    <span>I'm yellow because I'm referenced from the child of this current directory</span>
</p>

<p>
    <span>src="/subfolder/check_mark.png"</span>
    <img src="/subfolder/check_mark.png" />
    <span>I'm orange because I'm referenced from the child of the ROOT directory</span>
</p>

<p>
    <span>src="../subfolder/check_mark.png"</span>
    <img src="../subfolder/check_mark.png" />
    <span>I'm purple because I'm referenced from the parent of this current directory</span>
</p>

<p>
    <span>src="subfolder/subfolder/check_mark.png"</span>
    <img src="subfolder/subfolder/check_mark.png" />
    <span>I'm [broken] because there is no subfolder two children down from this current directory</span>
</p>

<p>
    <span>src="/subfolder/subfolder/check_mark.png"</span>
    <img src="/subfolder/subfolder/check_mark.png" />
    <span>I'm purple because I'm referenced two children down from the ROOT directory</span>
</p>

Now if you load up the index.html.en file located in the second subfolder
http://example.com/subfolder/subfolder/

This will be your output

Since destroy kind of destroys "everything", a cheap and simple solution when all you really want is to just "reset the data". Resetting your datasets to an empty array will work perfectly fine as well. So, if you have a dataset with labels, and an axis on each side:

window.myLine2.data.labels = [];
window.myLine2.data.datasets[0].data = [];
window.myLine2.data.datasets[1].data = [];

After this, you can simply call:

window.myLine2.data.labels.push(x);
window.myLine2.data.datasets[0].data.push(y);

or, depending whether you're using a 2d dataset:

window.myLine2.data.datasets[0].data.push({ x: x, y: y});

It'll be a lot more lightweight than completely destroying your whole chart/dataset, and rebuilding everything.

This is the easiest way to do this.

fin = open("a.txt")
f = open("file.txt", "wt")
for line in fin:
    f.write( line.replace('foo', 'bar') )
fin.close()
f.close()

I hope it will work for you.

If your builds on TravisCI are failing for this particular reason, you can resolve the issue by updating the Django Extensions in your requirements.txt

pip install --upgrade django-extensions

This will update the extensions to use Django 2+ modules.

>>> names = ['King', 'Queen', 'Joker']
>>> any(n in 'King and john' for n in names)
True

>>> all(n in 'King and Queen' for n in names)
False

It just reduce several line of code into one. You don't have to write lengthy code like:

for n in names:
    if n in 'King and john':
       print True
    else:
       print False

Can do, with jQuery:

$(document).ready(function() {
    $('.mandatory').each(function() {
        $(this).attr('title', $(this).attr('class'));
    });
});

sumall = summ + sumd + sumy

Your sumall is an integer. If you want the individual characters from it, convert it to a string first.

On the DataGridView, set the DataPropertyName of the columns to your column names of your DataTable.

What do you mean by "6 months"?

Is 2009-02-13 + 6 months == 2009-08-13? Or is it 2009-02-13 + 6*30 days?

import mx.DateTime as dt

#6 Months
dt.now()+dt.RelativeDateTime(months=6)
#result is '2009-08-13 16:28:00.84'

#6*30 days
dt.now()+dt.RelativeDateTime(days=30*6)
#result is '2009-08-12 16:30:03.35'

I had resolved this problem by:

• Turning off my wifi/ethernet connection and turn on.
• I typed: npm update in terminal to update npm.
• I tried to log out from the session and log in again

After that I tried the same npm command and the good thing was it worked out. I wasn't sure it is that simple.

I am using CENTOS 7

Just some examples on usage of array_split, split, hsplit and vsplit:

n [9]: a = np.random.randint(0,10,[4,4])

In [10]: a
Out[10]: 
array([[2, 2, 7, 1],
       [5, 0, 3, 1],
       [2, 9, 8, 8],
       [5, 7, 7, 6]])

Some examples on using array_split:
If you give an array or list as second argument you basically give the indices (before) which to 'cut'

# split rows into 0|1 2|3
In [4]: np.array_split(a, [1,3])
Out[4]:

       [0, 3, 1],
       [9, 8, 8],
       [7, 7, 6]])]

An integer as second arg. specifies the number of equal chunks:

In [6]: np.array_split(a, 2, axis=1)
Out[6]: 
[array([[2, 2],
       [5, 0],
       [2, 9],
       [5, 7]]),
 array([[7, 1],
       [3, 1],
       [8, 8],
       [7, 6]])]

split works the same but raises an exception if an equal split is not possible

In addition to array_split you can use shortcuts vsplit and hsplit.
vsplit and hsplit are pretty much self-explanatry:

In [11]: np.vsplit(a, 2)
Out[11]: 
[array([[2, 2, 7, 1],
       [5, 0, 3, 1]]),
 array([[2, 9, 8, 8],
       [5, 7, 7, 6]])]

In [12]: np.hsplit(a, 2)
Out[12]: 
[array([[2, 2],
       [5, 0],
       [2, 9],
       [5, 7]]),
 array([[7, 1],
       [3, 1],
       [8, 8],
       [7, 6]])]

Your #container should be outside of the #header-wrap, then specify a fixed height for #header-wrap, after, specify margin-top for #container equal to the #header-wrap's height. Something like this:

#header-wrap {
    position: fixed;
    height: 200px;
    top: 0;
    width: 100%;
    z-index: 100;
}
#container{ 
    margin-top: 200px;
}

I'm using pandas 0.16.2. This has better performance on my large dataset:

data.groupby(data.date.dt.year)

Using the dt option and playing around with weekofyear, dayofweek etc. becomes far easier.

Many ways to do this. You could use wildcards in double brackets:

str="/some/directory/file"
if [[ $str == /* ]]; then echo 1; else echo 0; fi

You can use substring expansion:

if [[ ${str:0:1} == "/" ]] ; then echo 1; else echo 0; fi

Or a regex:

if [[ $str =~ ^/ ]]; then echo 1; else echo 0; fi

Like this

png('filename.png')
# make plot
dev.off()

or this

# sometimes plots do better in vector graphics
svg('filename.svg')
# make plot
dev.off()

or this

pdf('filename.pdf')
# make plot
dev.off()

And probably others too. They're all listed together in the help pages.

To the best of my knowledge, you need to put your entire Java app in UTC timezone (so that Hibernate will store dates in UTC), and you'll need to convert to whatever timezone desired when you display stuff (at least we do it this way).

At startup, we do:

TimeZone.setDefault(TimeZone.getTimeZone("Etc/UTC"));

And set the desired timezone to the DateFormat:

fmt.setTimeZone(TimeZone.getTimeZone("Europe/Budapest"))

Yeah, use .match, rather than .search. The result from the .match call will return the actual string that was matched itself, but it can still be used as a boolean value.

var string = "Stackoverflow is the BEST";
var result = string.match(/best/i);
// result == 'BEST';

if (result){
    alert('Matched');
}

Using a regular expression like that is probably the tidiest and most obvious way to do that in JavaScript, but bear in mind it is a regular expression, and thus can contain regex metacharacters. If you want to take the string from elsewhere (eg, user input), or if you want to avoid having to escape a lot of metacharacters, then you're probably best using indexOf like this:

matchString = 'best';
// If the match string is coming from user input you could do
// matchString = userInput.toLowerCase() here.

if (string.toLowerCase().indexOf(matchString) != -1){
    alert('Matched');
}

The CSS code would be:

box-shadow: 0 0 10px 5px white;

That will shadow the entire DIV no matter its shape!

Edit:
As incidence pointed out this code has been DEPRECATED with the release of PHP 5.3.0 (2009-06-30) and should be used accordingly.

Just my two cents but I've developed this function and have been using it for a while with success. It's well documented and separated so you can easily change it.

// Checks if string is a URL
// @param string $url
// @return bool
function isURL($url = NULL) {
    if($url==NULL) return false;

    $protocol = '(http://|https://)';
    $allowed = '([a-z0-9]([-a-z0-9]*[a-z0-9]+)?)';

    $regex = "^". $protocol . // must include the protocol
             '(' . $allowed . '{1,63}\.)+'. // 1 or several sub domains with a max of 63 chars
             '[a-z]' . '{2,6}'; // followed by a TLD
    if(eregi($regex, $url)==true) return true;
    else return false;
}

Using plyr package:

library(plyr)

count(mydf$V1)

It will return you a frequency of each value.

You can use Case expression for returning a boolean in your select query like below.

@Query("SELECT CASE WHEN count(e) > 0 THEN true ELSE false END FROM MyEntity e where e.my_column = ?1")

You can use the name attr:

<script type="text/javascript" >
{
window.name ="This is my session";
}
</script> 

You still have to develop for yourself the format to use, or use a wrapper from an already existing library (mootools, Dojo etc).
You can also use cookies, but they are more heavy on performance, as they go back and forth from the client to the server, and are specific to one domain.

You cannot use the methods previously mentioned to download an image when running in Cordova. You will need to use the Cordova File Plugin. This will allow you to pick where to save it and leverage different persistence settings. Details here: https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-file/

Alternatively, you can convert the image to base64 then store the string in localStorage but this will fill your quota pretty quickly if you have many images or high-res.

Using pretty much the same approach as used by Burnash, for the final result you can use ...

=regexextract(A1,"[0-9]+")+A2

where A1 houses the string with text and number and A2 houses the date of interest

The index method of a list will do this for you. If you want to guarantee order, sort the list first using sorted(). Sorted accepts a cmp or key parameter to dictate how the sorting will happen:

a = [5, 4, 3]
print sorted(a).index(5)

Or:

a = ['one', 'aardvark', 'a']
print sorted(a, key=len).index('a')

JSP implicit objects likes session, request etc. are not available inside JSP declaration <%! %> tags.

You could use it directly in your expression as

<td>Username: </td>
<td><input type="text" value="<%= session.getAttribute("username") %>" /></td>

On other note, using scriptlets in JSP has been long deprecated. Use of EL (expression language) and JSTL tags is highly recommended. For example, here you could use EL as

<td>Username: </td>
<td><input type="text" value="${username}" /></td>

The best part is that scope resolution is done automatically. So, here username could come from page, or request, or session, or application scopes in that order. If for a particular instance you need to override this because of a name collision you can explicitly specify the scope as

<td><input type="text" value="${requestScope.username}" /></td> or,
<td><input type="text" value="${sessionScope.username}" /></td> or,
<td><input type="text" value="${applicationScope.username}" /></td>

I don't think there's a built-in way to do it without catching exceptions. You could instead use something like this:

public static MyEnum asMyEnum(String str) {
    for (MyEnum me : MyEnum.values()) {
        if (me.name().equalsIgnoreCase(str))
            return me;
    }
    return null;
}

Edit: As Jon Skeet notes, values() works by cloning a private backing array every time it is called. If performance is critical, you may want to call values() only once, cache the array, and iterate through that.

Also, if your enum has a huge number of values, Jon Skeet's map alternative is likely to perform better than any array iteration.

Yes, exactly what you're asking for is possible. It is not possible to 'decrypt' an MD5 password without help, but it is possible to re-encrypt an MD5 password into another algorithm, just not all in one go.

What you do is arrange for your users to be able to logon to your new system using the old MD5 password. At the point that they login they have given your login program an unhashed version of the password that you prove matches the MD5 hash that you have. You can then convert this unhashed password to your new hashing algorithm.

Obviously, this is an extended process because you have to wait for your users to tell you what the passwords are, but it does work.

When you join the new thread in the main thread, it will wait until the thread finishes, so the GUI will block even though you are using multithreading.

If you want to place the logic portion in a different class, you can subclass Thread directly, and then start a new object of this class when you press the button. The constructor of this subclass of Thread can receive a Queue object and then you will be able to communicate it with the GUI part. So my suggestion is:

1. Create a Queue object in the main thread
2. Create a new thread with access to that queue
3. Check periodically the queue in the main thread

Then you have to solve the problem of what happens if the user clicks two times the same button (it will spawn a new thread with each click), but you can fix it by disabling the start button and enabling it again after you call self.prog_bar.stop().

import Queue

class GUI:
    # ...

    def tb_click(self):
        self.progress()
        self.prog_bar.start()
        self.queue = Queue.Queue()
        ThreadedTask(self.queue).start()
        self.master.after(100, self.process_queue)

    def process_queue(self):
        try:
            msg = self.queue.get(0)
            # Show result of the task if needed
            self.prog_bar.stop()
        except Queue.Empty:
            self.master.after(100, self.process_queue)

class ThreadedTask(threading.Thread):
    def __init__(self, queue):
        threading.Thread.__init__(self)
        self.queue = queue
    def run(self):
        time.sleep(5)  # Simulate long running process
        self.queue.put("Task finished")

Inspired by this and other questions on SO, I've created a minimal open source basic-http-client that embodies most of the techniques found here.

Classes are simply blueprints to create objects from. The constructor is some code that are run every time you create an object. Therefor it does'nt make sense to have two constructors. What happens is that the second over write the first.

What you typically use them for is create variables for that object like this:

>>> class testing:
...     def __init__(self, init_value):
...         self.some_value = init_value

So what you could do then is to create an object from this class like this:

>>> testobject = testing(5)

The testobject will then have an object called some_value that in this sample will be 5.

>>> testobject.some_value
5

But you don't need to set a value for each object like i did in my sample. You can also do like this:

>>> class testing:
...     def __init__(self):
...         self.some_value = 5

then the value of some_value will be 5 and you don't have to set it when you create the object.

>>> testobject = testing()
>>> testobject.some_value
5

the >>> and ... in my sample is not what you write. It's how it would look in pyshell...

There is a package that converts it for you and returns the svg as a string to implement into your reactJS file.

https://www.npmjs.com/package/convert-svg-react

I don't believe the expression is sensical as it is.

Elvis means "if truthy, use the value, else use this other thing."

Your "other thing" is a closure, and the value is status != null, neither of which would seem to be what you want. If status is null, Elvis says true. If it's not, you get an extra layer of closure.

Why can't you just use:

(it.description == desc) && ((status == null) || (it.status == status))

Even if that didn't work, all you need is the closure to return the appropriate value, right? There's no need to create two separate find calls, just use an intermediate variable.

This is a sample program I wrote to check if a number is prime or not.

    elif x == 2:
        return True
    elif x%2==0:
        return False
    else:
        root = int(x**.5)+2
        for i in xrange (2,root):
            if x%i==0:
                return False
                y=1
        if y==0:
            return True

Use the properties-maven-plugin to write specific pom properties to a file at compile time, and then read that file at run time.

In your pom.xml:

<properties>
     <name>${project.name}</name>
     <version>${project.version}</version>
     <foo>bar</foo>
</properties>

<build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>properties-maven-plugin</artifactId>
            <version>1.0.0</version>
            <executions>
                <execution>
                    <phase>generate-resources</phase>
                    <goals>
                        <goal>write-project-properties</goal>
                    </goals>
                    <configuration>
                        <outputFile>${project.build.outputDirectory}/my.properties</outputFile>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

And then in .java:

java.io.InputStream is = this.getClass().getResourceAsStream("my.properties");
java.util.Properties p = new Properties();
p.load(is);
String name = p.getProperty("name");
String version = p.getProperty("version");
String foo = p.getProperty("foo");

I faced the same problem, and none of the options here helped me. Some mail services do not support specified styles. Here is my version, which solved the problem and works everywhere I checked:

<table>
    <tr>
        <td width="1">Gargantuan Word</td>
    </tr>
</table>

OR using CSS:

<table>
    <tr>
        <td style="width:1px">Gargantuan Word</td>
    </tr>
</table>

I had this concern when working on a Rails application with Docker.

My most preferred approach is to generally not use quotes. This includes not using quotes for:

• variables like ${RAILS_ENV}
• values separated by a colon (:) like postgres-log:/var/log/postgresql
• other strings values

I, however, use double-quotes for integer values that need to be converted to strings like:

• docker-compose version like version: "3.8"
• port numbers like "8080:8080"

However, for special cases like booleans, floats, integers, and other cases, where using double-quotes for the entry values could be interpreted as strings, please do not use double-quotes.

Here's a sample docker-compose.yml file to explain this concept:

version: "3"

services:
  traefik:
    image: traefik:v2.2.1
    command:
      - --api.insecure=true # Don't do that in production
      - --providers.docker=true
      - --providers.docker.exposedbydefault=false
      - --entrypoints.web.address=:80
    ports:
      - "80:80"
      - "8080:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro

That's all.

I hope this helps

BCrypt is a very good library, and there is a Java port of it.

String pooling

String pooling (sometimes also called as string canonicalisation) is a process of replacing several String objects with equal value but different identity with a single shared String object. You can achieve this goal by keeping your own Map (with possibly soft or weak references depending on your requirements) and using map values as canonicalised values. Or you can use String.intern() method which is provided to you by JDK.

At times of Java 6 using String.intern() was forbidden by many standards due to a high possibility to get an OutOfMemoryException if pooling went out of control. Oracle Java 7 implementation of string pooling was changed considerably. You can look for details in http://bugs.sun.com/view_bug.do?bug_id=6962931 and http://bugs.sun.com/view_bug.do?bug_id=6962930.

String.intern() in Java 6

In those good old days all interned strings were stored in the PermGen – the fixed size part of heap mainly used for storing loaded classes and string pool. Besides explicitly interned strings, PermGen string pool also contained all literal strings earlier used in your program (the important word here is used – if a class or method was never loaded/called, any constants defined in it will not be loaded).

The biggest issue with such string pool in Java 6 was its location – the PermGen. PermGen has a fixed size and can not be expanded at runtime. You can set it using -XX:MaxPermSize=96m option. As far as I know, the default PermGen size varies between 32M and 96M depending on the platform. You can increase its size, but its size will still be fixed. Such limitation required very careful usage of String.intern – you’d better not intern any uncontrolled user input using this method. That’s why string pooling at times of Java 6 was mostly implemented in the manually managed maps.

String.intern() in Java 7

Oracle engineers made an extremely important change to the string pooling logic in Java 7 – the string pool was relocated to the heap. It means that you are no longer limited by a separate fixed size memory area. All strings are now located in the heap, as most of other ordinary objects, which allows you to manage only the heap size while tuning your application. Technically, this alone could be a sufficient reason to reconsider using String.intern() in your Java 7 programs. But there are other reasons.

String pool values are garbage collected

Yes, all strings in the JVM string pool are eligible for garbage collection if there are no references to them from your program roots. It applies to all discussed versions of Java. It means that if your interned string went out of scope and there are no other references to it – it will be garbage collected from the JVM string pool.

Being eligible for garbage collection and residing in the heap, a JVM string pool seems to be a right place for all your strings, isn’t it? In theory it is true – non-used strings will be garbage collected from the pool, used strings will allow you to save memory in case then you get an equal string from the input. Seems to be a perfect memory saving strategy? Nearly so. You must know how the string pool is implemented before making any decisions.

I had the same question, and I tested 3 main solution :

1. (df != null) && (df.count > 0)
2. df.head(1).isEmpty() as @hulin003 suggest
3. df.rdd.isEmpty() as @Justin Pihony suggest

and of course the 3 works, however in term of perfermance, here is what I found, when executing the these methods on the same DF in my machine, in terme of execution time :

1. it takes ~9366ms
2. it takes ~5607ms
3. it takes ~1921ms
   

therefore I think that the best solution is df.rdd.isEmpty() as @Justin Pihony suggest

In python the with keyword is used when working with unmanaged resources (like file streams). It is similar to the using statement in VB.NET and C#. It allows you to ensure that a resource is "cleaned up" when the code that uses it finishes running, even if exceptions are thrown. It provides 'syntactic sugar' for try/finally blocks.

From Python Docs:

The with statement clarifies code that previously would use try...finally blocks to ensure that clean-up code is executed. In this section, I’ll discuss the statement as it will commonly be used. In the next section, I’ll examine the implementation details and show how to write objects for use with this statement.

The with statement is a control-flow structure whose basic structure is:

with expression [as variable]:
    with-block

The expression is evaluated, and it should result in an object that supports the context management protocol (that is, has __enter__() and __exit__() methods).

Update fixed VB callout per Scott Wisniewski's comment. I was indeed confusing with with using.

If the children have FKs linking them to the parent, then you can use DELETE CASCADE on the parent.

e.g.

CREATE TABLE supplier 
( supplier_id numeric(10) not null, 
 supplier_name varchar2(50) not null, 
 contact_name varchar2(50),  
 CONSTRAINT supplier_pk PRIMARY KEY (supplier_id) 
); 



CREATE TABLE products 
( product_id numeric(10) not null, 
 supplier_id numeric(10) not null, 
 CONSTRAINT fk_supplier 
   FOREIGN KEY (supplier_id) 
  REFERENCES supplier(supplier_id) 
  ON DELETE CASCADE 
); 

Delete the supplier, and it will delate all products for that supplier

You need just to follow those steps:

1. Right Click on your project: Run (As) -> Maven clean
2. Right Click on your project: Run (As) -> Maven install

After which, if the build fails when you do Maven Install, it means there is no web.xml file under WEB-INF or some problem associated with it. it really works

I did Install-Package Microsoft.AspNet.WebApi.Core -version 5.2.3 but it still did not work. Then looked in my project bin folder and saw that it still had the old System.Web.Mvc file.

So I manually copied the newer file from the package to the bin folder. Then I was up and running again.

• Daemon threads are those threads which provide general services for user threads (Example : clean up services - garbage collector)
• Daemon threads are running all the time until kill by the JVM
• Daemon Threads are treated differently than User Thread when JVM terminates , finally blocks are not called JVM just exits
• JVM doesn't terminates unless all the user threads terminate. JVM terminates if all user threads are dies
• JVM doesn't wait for any daemon thread to finish before existing and finally blocks are not called
• If all user threads dies JVM kills all the daemon threads before stops
• When all user threads have terminated, daemon threads can also be terminated and the main program terminates
• setDaemon() method must be called before the thread's start() method is invoked
• Once a thread has started executing its daemon status cannot be changed
• To determine if a thread is a daemon thread, use the accessor method isDaemon()

to indent a ul dropdown menu, use

/* Main Level */
ul{
  margin-left:10px;
}

/* Second Level */
ul ul{
  margin-left:15px;
}

/* Third Level */
ul ul ul{
  margin-left:20px;
}

/* and so on... */

You can indent the lis and (if applicable) the as (or whatever content elements you have) as well , each with differing effects. You could also use padding-left instead of margin-left, again depending on the effect you want.

Update

By default, many browsers use padding-left to set the initial indentation. If you want to get rid of that, set padding-left: 0px;

Still, both margin-left and padding-left settings impact the indentation of lists in different ways. Specifically: margin-left impacts the indentation on the outside of the element's border, whereas padding-left affects the spacing on the inside of the element's border. (Learn more about the CSS box model here)

Setting padding-left: 0; leaves the li's bullet icons hanging over the edge of the element's border (at least in Chrome), which may or may not be what you want.

Examples of padding-left vs margin-left and how they can work together on ul: https://jsfiddle.net/daCrosby/bb7kj8cr/1/

You can use the ?? operator to set the default value but first you must set the Nullable property to true in your dbml file in the required field (xx.Online)

var hht = from x in db.HandheldAssets
        join a in db.HandheldDevInfos on x.AssetID equals a.DevName into DevInfo
        from aa in DevInfo.DefaultIfEmpty()
        select new
        {
        AssetID = x.AssetID,
        Status = xx.Online ?? false
        };

Basically, no. That is an http header, so it is reasonable to cast to HttpWebRequest and set the .Referer (as you indicate in the question):

HttpWebRequest req = ...
req.Referer = "your url";

Actual Answer:

The default deserializer for enums uses .name() to deserialize, so it's not using the @JsonValue. So as @OldCurmudgeon pointed out, you'd need to pass in {"event": "FORGOT_PASSWORD"} to match the .name() value.

An other option (assuming you want the write and read json values to be the same)...

More Info:

There is (yet) another way to manage the serialization and deserialization process with Jackson. You can specify these annotations to use your own custom serializer and deserializer:

@JsonSerialize(using = MySerializer.class)
@JsonDeserialize(using = MyDeserializer.class)
public final class MyClass {
    ...
}

Then you have to write MySerializer and MyDeserializer which look like this:

MySerializer

public final class MySerializer extends JsonSerializer<MyClass>
{
    @Override
    public void serialize(final MyClass yourClassHere, final JsonGenerator gen, final SerializerProvider serializer) throws IOException, JsonProcessingException
    {
        // here you'd write data to the stream with gen.write...() methods
    }

}

MyDeserializer

public final class MyDeserializer extends org.codehaus.jackson.map.JsonDeserializer<MyClass>
{
    @Override
    public MyClass deserialize(final JsonParser parser, final DeserializationContext context) throws IOException, JsonProcessingException
    {
        // then you'd do something like parser.getInt() or whatever to pull data off the parser
        return null;
    }

}

Last little bit, particularly for doing this to an enum JsonEnum that serializes with the method getYourValue(), your serializer and deserializer might look like this:

public void serialize(final JsonEnum enumValue, final JsonGenerator gen, final SerializerProvider serializer) throws IOException, JsonProcessingException
{
    gen.writeString(enumValue.getYourValue());
}

public JsonEnum deserialize(final JsonParser parser, final DeserializationContext context) throws IOException, JsonProcessingException
{
    final String jsonValue = parser.getText();
    for (final JsonEnum enumValue : JsonEnum.values())
    {
        if (enumValue.getYourValue().equals(jsonValue))
        {

I am using Eclipse Java EE IDE for Web Developers. Version: Oxygen.1a Release (4.7.1a) in Windows 8.1 x64 with Apache Tomcat 8.5.24 (for testing purpose).

Port Name & Numbers for my Tomcat Server are :

Tomcat admin port   :   8005
HTTP/1.1            :   8081 (my Tomcat Listening Port Number)
AJP/1.3             :   8009

Peoples, for those the Tomcat were running good earlier, and sometimes sudden after stopping tomcat server explicitly by pressing the below shown image button or may be other reasons.

Either they continuously failed to start/restart the tomcat with below said error:

Server Tomcat vX.Y Server at localhost failed to start.

or sometimes the Tomcat Server is started but instead of showing Tomcat Homepage in web browser, it is throwing client exception HTTP Status 404 – Not Found. in preferred web browser.

possibly, there are many reasons i.e. wrong Host name defined, Wrong Tomcat Server Locations defined in eclipse, project JDK/JRE version mismatch with Tomcat JRE dependent version, maven project version mismatch due to maven.compiler.source and maven.compiler.target version not defined under properties tag, mismatch version of project facet Dynamic Web Module to 2.5/3.0, Sometimes Tomcat Server is running on Windows Services level, previous stopped Tomcat port number were still listening and the processing pid were not killed in Tomcat defined timespan Timeouts Stop (in seconds): 15(by default) in eclipse and pid still running, failed to start in defined Start (in seconds): XX, etc.

Here I will give the resolution on, how to check and kill the running existing Tomcat port number's processing pid(beware, you must be aware with after effects).

In Windows, open you command prompt, and follow steps(my tomcat HTTP port is 8081):

netstat -ano | findstr :8081
TCP    0.0.0.0:8081           0.0.0.0:0              LISTENING       2284
TCP    [::]:8081              [::]:0                 LISTENING       2284

if any listening is being there, above command will list details of port listening along with processing pid at last of the line(here pid is 2284).

now kill the running pid like:

taskkill /PID 2284 /F
SUCCESS: The process with PID 2284 has been terminated.

also illustrated the above two steps like following:

Now, after resolving above illustrated reason, start the Tomcat Server.

Use Integer.compare(int, int). And don'try to micro-optimize your code unless you can prove that you have a performance issue.

You should write the pickled data with a lower protocol number in Python 3. Python 3 introduced a new protocol with the number 3 (and uses it as default), so switch back to a value of 2 which can be read by Python 2.

Check the protocolparameter in pickle.dump. Your resulting code will look like this.

pickle.dump(your_object, your_file, protocol=2)

There is no protocolparameter in pickle.load because pickle can determine the protocol from the file.

"<name> <substring>"[/.*<([^>]*)/,1]
=> "substring"

No need to use scan, if we need only one result.
No need to use Python's match, when we have Ruby's String[regexp,#].

See: http://ruby-doc.org/core/String.html#method-i-5B-5D

Note: str[regexp, capture] ? new_str or nil

Use this for your code

<ul class="nav nav-tabs" style="margin-top:10em;">
  <li class="active" data-toggle="tab"><a href="#">Assign</a></li>
<li data-toggle="tab"><a href="#">Two</a></li>
<li data-toggle="tab"><a href="#">Three</a></li>

This should work.

using System.Drawing.Printing;

...

PrinterSettings ps = new PrinterSettings();
ps.PrinterName = "The printer name"; // Load the appropriate printer's setting

After that, the various properties of PrinterSettings can be read.

Note that ps.isValid() can see if the printer actually exists.

Edit: One additional comment. Microsoft recommends you use a PrintDocument and modify its PrinterSettings rather than creating a PrinterSettings directly.

I am working on a tutorial for REST web services at www.udemy.com (REST Java Web Services). The example in the tutorial said that in order to have SSL, we must have a folder called "trust_store" in my eclipse "client" project that should contain a "key store" file (we had a "client" project to call the service, and "service" project that contained the REST web service - 2 projects in the same eclipse workspace, one the client, the other the service). To keep things simple, they said to copy "keystore.jks" from the glassfish app server (glassfish\domains\domain1\config\keystore.jks) we are using and put it into this "trust_store" folder that they had me make in the client project. That seems to make sense: the self-signed certs in the server's key_store would correspond to the certs in the client trust_store. Now, doing this, I was getting the error that the original post mentions. I have googled this and read that the error is due to the "keystore.jks" file on the client not containing a trusted/signed certificate, that the certificate it finds is self-signed.

To keep things clear, let me say that as I understand it, the "keystore.jks" contains self-signed certs, and the "cacerts.jks" file contains CA certs (signed by the CA). The "keystore.jks" is the "keystore" and the "cacerts.jks" is the "trust store". As "Bruno", a commenter, says above, "keystore.jks" is local, and "cacerts.jks" is for remote clients.

So, I said to myself, hey, glassfish also has the "cacerts.jks" file, which is glassfish's trust_store file. cacerts.jsk is supposed to contain CA certificates. And apparently I need my trust_store folder to contain a key store file that has at least one CA certificate. So, I tried putting the "cacerts.jks" file in the "trust_store" folder I had made, on my client project, and changing the VM properties to point to "cacerts.jks" instead of "keystore.jks". That got rid of the error. I guess all it needed was a CA cert to work.

This may not be ideal for production, or even for development beyond just getting something to work. For instance you could probably use "keytool" command to add CA certs to the "keystore.jks" file in the client. But anyway hopefully this at least narrows down the possible scenarios that could be going on here to cause the error.

ALSO: my approach seemed to be useful for the client (server cert added to client trust_store), it looks like the comments above to resolve the original post are useful for the server (client cert added to server trust_store). Cheers.

Eclipse project setup:

• MyClientProject
• src
• test
• JRE System Library
• ...
• trust_store
  ---cacerts.jks ---keystore.jks

Snippet from MyClientProject.java file:

static {
  // Setup the trustStore location and password
  System.setProperty("javax.net.ssl.trustStore","trust_store/cacerts.jks");
  // comment out below line
  System.setProperty("javax.net.ssl.trustStore","trust_store/keystore.jks");
  System.setProperty("javax.net.ssl.trustStorePassword", "changeit");
  //System.setProperty("javax.net.debug", "all");

  // for localhost testing only
  javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(new javax.net.ssl.HostnameVerifier() {
        public boolean verify(String hostname, javax.net.ssl.SSLSession sslSession) {
          return hostname.equals("localhost");
        }

  });
}

Old question - but I recently needed this along with the row count... here is a query for both - sorted by row count desc:

SELECT t.owner, 
       t.table_name, 
       t.num_rows, 
       Count(*) 
FROM   all_tables t 
       LEFT JOIN all_tab_columns c 
              ON t.table_name = c.table_name 
WHERE  num_rows IS NOT NULL 
GROUP  BY t.owner, 
          t.table_name, 
          t.num_rows 
ORDER  BY t.num_rows DESC; 

Use following in your CSS

div {
    -webkit-transform: rotate(90deg); /* Safari and Chrome */
    -moz-transform: rotate(90deg);   /* Firefox */
    -ms-transform: rotate(90deg);   /* IE 9 */
    -o-transform: rotate(90deg);   /* Opera */
    transform: rotate(90deg);
} 

You can use Ellipsis yourself, in custom slicing situations like numpy has done, but it has no usage in any builtin class.

I don't know if it was added specifically for use in numpy, but I certainly haven't seen it used elsewhere.

The latest version of Springsource STS (3.6) supports Tomcat 8. It is based on eclipse Luna 4.4 and supports Java 8. Have at it!

"Default Namespace textbox in project properties is disabled" Same with me (VS 2010). I edited the project file ("xxx.csproj") and tweaked the item. That changed the default namespace.

do not place *jsp or *html in root folder of webapp and images you want to display in same root folder browser cannot acess the image in WEB-INF folder

In my case this problem happened when I imported a Maven project into Eclipse. To solve this, I added the following in pom.xml:

<properties>
   ...
   <maven.compiler.source>1.8</maven.compiler.source>
   <maven.compiler.target>1.8</maven.compiler.target>
</properties>

Then in the context menu of the project, go to "Maven -> Update Project ...", and press OK.

That's it. Hope this helps.

The Dr. Memory (http://drmemory.org) tool comes with a system call tracing tool called drstrace that lists all system calls made by a target application along with their arguments: http://drmemory.org/strace_for_windows.html

For programmatically enforcing system call policies, you could use the same underlying engines as drstrace: the DynamoRIO tool platform (http://dynamorio.org) and the DrSyscall system call monitoring library (http://drmemory.org/docs/page_drsyscall.html). These use dynamic binary translation technology, which does incur some overhead (20%-30% in steady state, but much higher when running new code such as launching a big desktop app), which may or may not be suitable for your purposes.

I got the same error when I installed Laravel version 8.27.0: The error is as follow:

But when I saw my app/Providers/RouteServiceProvider.php I have namespaces inside my boot method, then I just uncommented this => "protected $namespace = 'App\Http\Controllers';"

According to my tests with Chrome:

If you set a number input to a Number, then it works fine.

If you set a number input to a String that contains nothing but a number, then it works fine.

If you set a number input to a String that contains a number and some whitespace, then it blanks the input.

You probably have a space or a new line after the data in the server response that you actually care about.

Use document.getElementById("points").value = parseInt(request.responseText, 10); instead.

As khaos said, a destination unreachable could also mean that something is blocking the way from or to your destination. For example an ACL that filters bad IP addresses.

I believe you need your support package in both Library and application. However, to fix this, make sure you have same file at both locations (same checksum).

Simply copy the support-package file from one location and copy at another then clean+refresh your library/project and you should be good to go.

Use this regular expression to match ten digits only:

@"^\d{10}$"

To find a sequence of ten consecutive digits anywhere in a string, use:

@"\d{10}"

Note that this will also find the first 10 digits of an 11 digit number. To search anywhere in the string for exactly 10 consecutive digits and not more you can use negative lookarounds:

@"(?<!\d)\d{10}(?!\d)"

My problem occurs when I try to open https. I don't use SSL.

It's Tomcat bug.

Today 12/02/2017 newest official version from Debian repositories is Tomcat 8.0.14

Solution is to download from official site and install newest package of Tomcat 8, 8.5, 9 or upgrade to newest version(8.5.x) from jessie-backports

Debian 8

Add to /etc/apt/sources.list

deb http://ftp.debian.org/debian jessie-backports main

Then update and install Tomcat from jessie-backports

sudo apt-get update && sudo apt-get -t jessie-backports install tomcat8

My problem was actually a problem of bad planning with the JSON object rather than an actual logic issue. What I ended up doing was organize the object as follows, per a suggestion from user2736012.

{
"dialog":
{
    "trunks":[
    {
        "trunk_id" : "1",
        "message": "This is just a JSON Test"
    },
    {
        "trunk_id" : "2",
        "message": "This is a test of a bit longer text. Hopefully this will at the very least create 3 lines and trigger us to go on to another box. So we can test multi-box functionality, too."
    }
    ]
}
}

At that point, I was able to do a fairly simple for loop based on the total number of objects.

var totalMessages = Object.keys(messages.dialog.trunks).length;

    for ( var i = 0; i < totalMessages; i++)
    {
        console.log("ID: " + messages.dialog.trunks[i].trunk_id + " Message " + messages.dialog.trunks[i].message);
    }

My method for getting totalMessages is not supported in all browsers, though. For my project, it actually doesn't matter, but beware of that if you choose to use something similar to this.

I guess nobody understood the question. I guess what this guy wanted was something like this:

return new (class implements MyInterface {
    @Override
    public void myInterfaceMethod() { /*do something*/ }
});

because this would allow things like multiple interface implementations:

return new (class implements MyInterface, AnotherInterface {
    @Override
    public void myInterfaceMethod() { /*do something*/ }

    @Override
    public void anotherInterfaceMethod() { /*do something*/ }
});

this would be really nice indeed; but that's not allowed in Java.

What you can do is use local classes inside method blocks:

public AnotherInterface createAnotherInterface() {
    class LocalClass implements MyInterface, AnotherInterface {
        @Override
        public void myInterfaceMethod() { /*do something*/ }

        @Override
        public void anotherInterfaceMethod() { /*do something*/ }
    }
    return new LocalClass();
}

The actual issue should be with the OS architecture, the JDK (32bit or 64 bit) installed and the eclipse type u installed.

Bring them in sync, things would work completely fine.

Just have a check at the Eventlog as mentioned by @Viji Ideally u should encounter error like RADAR_PRE_LEAK_64

? extends HasWord

means "A class/interface that extends HasWord." In other words, HasWord itself or any of its children... basically anything that would work with instanceof HasWord plus null.

In more technical terms, ? extends HasWord is a bounded wildcard, covered in Item 31 of Effective Java 3rd Edition, starting on page 139. The same chapter from the 2nd Edition is available online as a PDF; the part on bounded wildcards is Item 28 starting on page 134.

Update: PDF link was updated since Oracle removed it a while back. It now points to the copy hosted by the Queen Mary University of London's School of Electronic Engineering and Computer Science.

Update 2: Lets go into a bit more detail as to why you'd want to use wildcards.

If you declare a method whose signature expect you to pass in List<HasWord>, then the only thing you can pass in is a List<HasWord>.

However, if said signature was List<? extends HasWord> then you could pass in a List<ChildOfHasWord> instead.

Note that there is a subtle difference between List<? extends HasWord> and List<? super HasWord>. As Joshua Bloch put it: PECS = producer-extends, consumer-super.

What this means is that if you are passing in a collection that your method pulls data out from (i.e. the collection is producing elements for your method to use), you should use extends. If you're passing in a collection that your method adds data to (i.e. the collection is consuming elements your method creates), it should use super.

This may sound confusing. However, you can see it in List's sort command (which is just a shortcut to the two-arg version of Collections.sort). Instead of taking a Comparator<T>, it actually takes a Comparator<? super T>. In this case, the Comparator is consuming the elements of the List in order to reorder the List itself.

var newList = list.OrderBy(x => x.Product.Name).Reverse()

This should do the job.

Your first problem was you weren't using your compare symbols correctly.

< less than
> greater than
<= less than or equal to
>= greater than or equal to

To answer your other questions; get the condition to work on every cell in the column and what about blanks?

What about blanks?

Add an extra IF condition to check if the cell is blank or not, if it isn't blank perform the check. =IF(B2="","",B2<=TODAY())

To extend The.Anyi.9's answer, you should also be aware of the different types of line break in general use. Dependent on where your file originated, you may want to look at making sure you catch all the alternatives...

string replaceWith = "";
string removedBreaks = Line.Replace("\r\n", replaceWith).Replace("\n", replaceWith).Replace("\r", replaceWith);

should get you going...

php://input is a read-only stream that allows you to read raw data from the request body. In the case of POST requests, it is preferable to use php://input instead of $HTTP_RAW_POST_DATA as it does not depend on special php.ini directives. Moreover, for those cases where $HTTP_RAW_POST_DATA is not populated by default, it is a potentially less memory intensive alternative to activating always_populate_raw_post_data.

For the bytes uploaded it is quite easy. Just monitor the xhr.upload.onprogress event. The browser knows the size of the files it has to upload and the size of the uploaded data, so it can provide the progress info.

For the bytes downloaded (when getting the info with xhr.responseText), it is a little bit more difficult, because the browser doesn't know how many bytes will be sent in the server request. The only thing that the browser knows in this case is the size of the bytes it is receiving.

There is a solution for this, it's sufficient to set a Content-Length header on the server script, in order to get the total size of the bytes the browser is going to receive.

For more go to https://developer.mozilla.org/en/Using_XMLHttpRequest .

Example: My server script reads a zip file (it takes 5 seconds):

$filesize=filesize('test.zip');

header("Content-Length: " . $filesize); // set header length
// if the headers is not set then the evt.loaded will be 0
readfile('test.zip');
exit 0;

Now I can monitor the download process of the server script, because I know it's total length:

function updateProgress(evt) 
{
   if (evt.lengthComputable) 
   {  // evt.loaded the bytes the browser received
      // evt.total the total bytes set by the header
      // jQuery UI progress bar to show the progress on screen
     var percentComplete = (evt.loaded / evt.total) * 100;  
     $('#progressbar').progressbar( "option", "value", percentComplete );
   } 
}   
function sendreq(evt) 
{  
    var req = new XMLHttpRequest(); 
    $('#progressbar').progressbar();    
    req.onprogress = updateProgress;
    req.open('GET', 'test.php', true);  
    req.onreadystatechange = function (aEvt) {  
        if (req.readyState == 4) 
        {  
             //run any callback here
        }  
    };  
    req.send(); 
}

This is an answered question, but I'll give my "one cent":

Business rules belong in the model. The "model" always consists of (logically or physically separated):

• presentation model - a set of classes that is well suited for use in the view (it's tailored toward specific UI/presentation),
• domain model - the UI-independent portion of the model, and
• repository - the storage-aware portion of the "model".

Business rules live in the domain model, are exposed in a presentation-suitable form to the "presentation" model and are sometimes duplicated (or also enforced) in the "data layer".

You probably did some history rewriting? Your local branch diverged from the one on the server. Run this command to get a better understanding of what happened:

gitk HEAD @{u}

I would strongly recommend you try to understand where this error is coming from. To fix it, simply run:

git push -f

The -f makes this a “forced push” and overwrites the branch on the server. That is very dangerous when you are working in team. But since you are on your own and sure that your local state is correct this should be fine. You risk losing commit history if that is not the case.

Why not simply use List#equals?

assertEquals(argumentComponents, imapPathComponents);

Contract of List#equals:

two lists are defined to be equal if they contain the same elements in the same order.

$users = Users::all()->unique('name');

You can use strstream. It's formally deprecated, but it's still a great tool if you need to work with C strings, i think.

char result[100]; // max size 100
std::ostrstream s(result, sizeof result - 1);

s << one << two << std::ends;
result[99] = '\0';

This will write one and then two into the stream, and append a terminating \0 using std::ends. In case both strings could end up writing exactly 99 characters - so no space would be left writing \0 - we write one manually at the last position.

You can fix this issue without opening the storyboard as a source. This warning is triggered by UILabels if numberOfLines !=1 and deployment target is < 8.0

HOW TO FIND IT?

1. Go to Issue Navigator (CMD+8) and Select latest built with the warning
2. Locate the warning(s) (search for "Automatic Preferred Max Layout") and press expand button on the right
   
3. Find the Object ID of the UILabel
4. Open the Storyboard and SEARCH (CMD+f) for the object. It will SELECT AND HIGHLIGHT the UILabel
5. Set Preferred Width = 0 "Explicit" as others suggested

Also this issue occurres when the response contenttype is not application/json. In my case response contenttype was text/html and i faced this problem. I changed it to application/json then it worked.

XmlDocument doc = new XmlDocument();
doc.LoadXml(str);

Where str is your XML string. See the MSDN article for more info.

You say that the matrices are the same dimensions, and yet you are trying to perform matrix multiplication on them. Multiplication of matrices with the same dimension is only possible if they are square. In your case, you get an assertion error, because the dimensions are not square. You have to be careful when multiplying matrices, as there are two possible meanings of multiply.

Matrix multiplication is where two matrices are multiplied directly. This operation multiplies matrix A of size [a x b] with matrix B of size [b x c] to produce matrix C of size [a x c]. In OpenCV it is achieved using the simple * operator:

C = A * B

Element-wise multiplication is where each pixel in the output matrix is formed by multiplying that pixel in matrix A by its corresponding entry in matrix B. The input matrices should be the same size, and the output will be the same size as well. This is achieved using the mul() function:

output = A.mul(B);

prop_cycle

color_cycle was deprecated in 1.5 in favor of this generalization: http://matplotlib.org/users/whats_new.html#added-axes-prop-cycle-key-to-rcparams

# cycler is a separate package extracted from matplotlib.
from cycler import cycler
import matplotlib.pyplot as plt

plt.rc('axes', prop_cycle=(cycler('color', ['r', 'g', 'b'])))
plt.plot([1, 2])
plt.plot([2, 3])
plt.plot([3, 4])
plt.plot([4, 5])
plt.plot([5, 6])
plt.show()

Also shown in the (now badly named) example: http://matplotlib.org/1.5.1/examples/color/color_cycle_demo.html mentioned at: https://stackoverflow.com/a/4971431/895245

Tested in matplotlib 1.5.1.

Sure. Just list the files:

$ svn ci -m "Fixed all those horrible crashes" foo bar baz graphics/logo.png

I'm not aware of a way to tell it to ignore a certain set of files. Of course, if the files you do want to commit are easily listed by the shell, you can use that:

$ svn ci -m "No longer sets printer on fire" printer-driver/*.c

You can also have the svn command read the list of files to commit from a file:

$ svn ci -m "Now works" --targets fix4711.txt

If you have a SSHClient, you can also use open_sftp():

import paramiko


# lets say you have SSH client...
client = paramiko.SSHClient()

sftp = client.open_sftp()

# then you can use upload & download as shown above
...

You can use the Contains() extension method:

list.Where(r => listofIds.Contains(r.Id))

You can try the pipe functionality in sh.py:

import sh
print sh.grep(sh.ps("-ax"), "process_name")

Quoting the Forms Page in the HTML manual:

Buttons created with the BUTTON element function just like buttons created with the INPUT element, but they offer richer rendering possibilities: the BUTTON element may have content. For example, a BUTTON element that contains an image functions like and may resemble an INPUT element whose type is set to "image", but the BUTTON element type allows content.

There is an codeproject project avaliable HERE that provides this functuanility.

Following many threads here on SO and other boards this cant be done with the normal MessageBox.

Edit:

I have an idea that is a bit ehmmm yeah..

Use a timer and start in when the MessageBox appears. If your MessageBox only listens to the OK Button (only 1 possibility) then use the OnTick-Event to emulate an ESC-Press with SendKeys.Send("{ESC}"); and then stop the timer.

Here's a simple solution that doesn't require any hard-to-read LINQ or any prior sorting of the list.

   private static void CheckForDuplicateItems(List<string> items)
    {
        if (items == null ||
            items.Count == 0)
            return;

        for (int outerIndex = 0; outerIndex < items.Count; outerIndex++)
        {
            for (int innerIndex = 0; innerIndex < items.Count; innerIndex++)
            {
                if (innerIndex == outerIndex) continue;
                if (items[outerIndex].Equals(items[innerIndex]))
                {
                    // Duplicate Found
                }
            }
        }
    }

using (SqlConnection conn = new SqlConnection())
using (SqlCommand cmd = conn.CreateCommand())
{
    cmd.CommandText = "INSERT INTO <table> (<date_column>) VALUES ('2010-01-01 12:00')";
    cmd.ExecuteNonQuery();
}

It's been awhile since I wrote this stuff, so this may not be perfect. but the general idea is there.

WARNING: this is unsanitized. You should use parameters to avoid injection attacks.

EDIT: Since Jon insists.

This happened to me by having a link to external js outside the head just before the end of the body section. You know, one of these:

<script src="http://somesite.net/js/somefile.js">

It did not have anything to do with JQuery.

You would probably see the same doing something like this:

var script = $("<script></script>");
script.attr("src", basepath + "someotherfile.js");
$(document.body).append(script);

But I haven't tested that idea.

During the preflight request, you should see the following two headers: Access-Control-Request-Method and Access-Control-Request-Headers. These request headers are asking the server for permissions to make the actual request. Your preflight response needs to acknowledge these headers in order for the actual request to work.

For example, suppose the browser makes a request with the following headers:

Origin: http://yourdomain.com
Access-Control-Request-Method: POST
Access-Control-Request-Headers: X-Custom-Header

Your server should then respond with the following headers:

Access-Control-Allow-Origin: http://yourdomain.com
Access-Control-Allow-Methods: GET, POST
Access-Control-Allow-Headers: X-Custom-Header

Pay special attention to the Access-Control-Allow-Headers response header. The value of this header should be the same headers in the Access-Control-Request-Headers request header, and it can not be '*'.

Once you send this response to the preflight request, the browser will make the actual request. You can learn more about CORS here: http://www.html5rocks.com/en/tutorials/cors/

import { undefined } from 'undefined-is-a-function';
// Fixed! undefined is now a function.

edit the file /etc/eclipse.ini, so as to contain entry as;

-Duser.name=myname

Restart the "eclipse" and now, on creation of any new file, with wizard (c/c++/java), it will use "myname" in place of ${user}.

Do display: inline-block:

#report-upload-form label {
    padding-left:26px;
    width:125px;
    text-transform: uppercase;
    display:inline-block
