This code is to solve our problem to set unique key for existing table

alter ignore table ioni_groups add unique (group_name);

psql's inline help:

\h ALTER TABLE

Also documented in the postgres docs (an excellent resource, plus easy to read, too).

ALTER TABLE tablename ADD CONSTRAINT constraintname UNIQUE (columns);

Yes, MySQL allows multiple NULLs in a column with a unique constraint.

CREATE TABLE table1 (x INT NULL UNIQUE);
INSERT table1 VALUES (1);
INSERT table1 VALUES (1);   -- Duplicate entry '1' for key 'x'
INSERT table1 VALUES (NULL);
INSERT table1 VALUES (NULL);
SELECT * FROM table1;

Result:

x
NULL
NULL
1

This is not true for all databases. SQL Server 2005 and older, for example, only allows a single NULL value in a column that has a unique constraint.

It looks like you are not providing a value for the primary key field DB_ID. If that is a primary key, you must provide a unique value for that column. The only way not to provide it would be to create a database trigger that, on insert, would provide a value, most likely derived from a sequence.

If this is a restoration from another database and there is a sequence on this new instance, it might be trying to reuse a value. If the old data had unique keys from 1 - 1000 and your current sequence is at 500, it would be generating values that already exist. If a sequence does exist for this table and it is trying to use it, you would need to reconcile the values in your table with the current value of the sequence.

You can use SEQUENCE_NAME.CURRVAL to see the current value of the sequence (if it exists of course)

Here's another way through the GUI that does exactly what your script does even though it goes through Indexes (not Constraints) in the object explorer.

1. Right click on "Indexes" and click "New Index..." (note: this is disabled if you have the table open in design view)

2. Give new index a name ("U_Name"), check "Unique", and click "Add..."

3. Select "Name" column in the next windown

4. Click OK in both windows

Note: In Kotlin the syntax for declaring the arrays in annotations uses arrayOf(...) instead of {...}

@Entity
@Table(uniqueConstraints=arrayOf(UniqueConstraint(columnNames=arrayOf("book", "chapter_number"))))
class Chapter(@ManyToOne var book:Book,
              @Column var chapterNumber:Int)

Note: As of Kotlin 1.2 its is possible to use the [...] syntax so the code become much simpler

@Entity
@Table(uniqueConstraints=[UniqueConstraint(columnNames=["book", "chapter_number"])])
class Chapter(@ManyToOne var book:Book,
              @Column var chapterNumber:Int)

A slight extension to the answer given, so, hopefully useful to the asker and anyone else looking.

You can also SELECT the values you want to delete. But watch out for the Error 1093 - You can't specify the target table for update in FROM clause.

DELETE FROM
    orders_products_history
WHERE
    (branchID, action) IN (
    SELECT
        branchID,
        action
    FROM
        (
        SELECT
            branchID,
            action
        FROM
            orders_products_history
        GROUP BY
            branchID,
            action
        HAVING
            COUNT(*) > 10000
        ) a
    );

I wanted to delete all history records where the number of history records for a single action/branch exceed 10,000. And thanks to this question and chosen answer, I can.

Hope this is of use.

Richard.

I figured it out from the PostgreSQL docs, the exact syntax is:

ALTER TABLE the_table ADD CONSTRAINT constraint_name UNIQUE (thecolumn);

Thanks Fred.

If you want to avoid duplicates in future. Create another column say id2.

UPDATE tablename SET id2 = id;

Now add the unique on two columns:

alter table tablename add unique index(columnname, id2);

This statement works for me

  ALTER TABLE table_name DROP UNIQUE (column_name);

Put the UNIQUE declaration within the column definition section; working example:

CREATE TABLE a (
    i INT,
    j INT,
    UNIQUE(i, j) ON CONFLICT REPLACE
);

In [6]: os.listdir?

Type:       builtin_function_or_method
String Form:<built-in function listdir>
Docstring:
listdir(path) -> list_of_strings
Return a list containing the names of the entries in the directory.
path: path of directory to list
The list is in **arbitrary order**.  It does not include the special
entries '.' and '..' even if they are present in the directory.

My situation was not covered by any of the above answers. I found the following: MSDN article on threading that explains that when stuck in some primitive native threading operations, the debugger can't access the data. As an example, when a thread is sitting on Task.Wait(), this comes up.

The Rule of Three is a rule of thumb for C++, basically saying

If your class needs any of

• a copy constructor,
• an assignment operator,
• or a destructor,

defined explictly, then it is likely to need all three of them.

The reasons for this is that all three of them are usually used to manage a resource, and if your class manages a resource, it usually needs to manage copying as well as freeing.

If there is no good semantic for copying the resource your class manages, then consider to forbid copying by declaring (not defining) the copy constructor and assignment operator as private.

(Note that the forthcoming new version of the C++ standard (which is C++11) adds move semantics to C++, which will likely change the Rule of Three. However, I know too little about this to write a C++11 section about the Rule of Three.)

You can use the .blur() method. See http://api.jquery.com/blur/

The error in the Google DevTools are caused Google extensions.

1. I clicked on my Google icon in the browser
2. created a guest profile at the bottom of the popup window.
3. I then pasted my localhost address and voila!!

No more errors in the console.

Sam's solution should be sufficient. I've used combination of both histogram difference and template matching because not one method was working for me 100% of the times. I've given less importance to histogram method though. Here's how I've implemented in simple python script.

import cv2

class CompareImage(object):

    def __init__(self, image_1_path, image_2_path):
        self.minimum_commutative_image_diff = 1
        self.image_1_path = image_1_path
        self.image_2_path = image_2_path

    def compare_image(self):
        image_1 = cv2.imread(self.image_1_path, 0)
        image_2 = cv2.imread(self.image_2_path, 0)
        commutative_image_diff = self.get_image_difference(image_1, image_2)

        if commutative_image_diff < self.minimum_commutative_image_diff:
            print "Matched"
            return commutative_image_diff
        return 10000 //random failure value

    @staticmethod
    def get_image_difference(image_1, image_2):
        first_image_hist = cv2.calcHist([image_1], [0], None, [256], [0, 256])
        second_image_hist = cv2.calcHist([image_2], [0], None, [256], [0, 256])

        img_hist_diff = cv2.compareHist(first_image_hist, second_image_hist, cv2.HISTCMP_BHATTACHARYYA)
        img_template_probability_match = cv2.matchTemplate(first_image_hist, second_image_hist, cv2.TM_CCOEFF_NORMED)[0][0]
        img_template_diff = 1 - img_template_probability_match

        # taking only 10% of histogram diff, since it's less accurate than template method
        commutative_image_diff = (img_hist_diff / 10) + img_template_diff
        return commutative_image_diff


    if __name__ == '__main__':
        compare_image = CompareImage('image1/path', 'image2/path')
        image_difference = compare_image.compare_image()
        print image_difference

Since IPv6-Adresses are written in Hex-notation you can use "Hexspeak" (numbers 0-9 and letters a-f) in Adresses.

There are a number of words you can use as valid adresses to better momorize them.

If you ping6 www.facebook.com -n you will get something like "2a03:2880:f01c:601:face:b00c:0:1".

Here are some examples:

• :affe:: (Affe - German for Monkey - seen at a vlan for management board)
• :1bad:babe:: (one bad babe - seen at a smtp-honeypot)
• :badc:ab1e:: (bad cable - seen as subnet for a unsecure vlan)
• :da7a:: (Data - seen for fileservers)
• :d1a1:: (Dial - seen for VPN Dial-In)

With REGEXP_SUBSTR is as simple as:

SELECT REGEXP_SUBSTR(t.column_one, '[^ ]+', 1, 1) col_one,
       REGEXP_SUBSTR(t.column_one, '[^ ]+', 1, 2) col_two
FROM YOUR_TABLE t;

In your CSS file:

.TableHeader { width: 100px; }

This will set all of the td tags below each header to 100px. You can also add a width definition (in the markup) to each individual th tag, but the above solution would be easier.

A simple way using std::next_permutation:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
    int n, r;
    std::cin >> n;
    std::cin >> r;

    std::vector<bool> v(n);
    std::fill(v.end() - r, v.end(), true);

    do {
        for (int i = 0; i < n; ++i) {
            if (v[i]) {
                std::cout << (i + 1) << " ";
            }
        }
        std::cout << "\n";
    } while (std::next_permutation(v.begin(), v.end()));
    return 0;
}

or a slight variation that outputs the results in an easier to follow order:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
   int n, r;
   std::cin >> n;
   std::cin >> r;

   std::vector<bool> v(n);
   std::fill(v.begin(), v.begin() + r, true);

   do {
       for (int i = 0; i < n; ++i) {
           if (v[i]) {
               std::cout << (i + 1) << " ";
           }
       }
       std::cout << "\n";
   } while (std::prev_permutation(v.begin(), v.end()));
   return 0;
}

A bit of explanation:

It works by creating a "selection array" (v), where we place r selectors, then we create all permutations of these selectors, and print the corresponding set member if it is selected in in the current permutation of v.

You can implement it if you note that for each level r you select a number from 1 to n.

In C++, we need to 'manually' keep the state between calls that produces results (a combination): so, we build a class that on construction initialize the state, and has a member that on each call returns the combination while there are solutions: for instance

#include <iostream>
#include <iterator>
#include <vector>
#include <cstdlib>

using namespace std;

struct combinations
{
    typedef vector<int> combination_t;

    // initialize status
   combinations(int N, int R) :
       completed(N < 1 || R > N),
       generated(0),
       N(N), R(R)
   {
       for (int c = 1; c <= R; ++c)
           curr.push_back(c);
   }

   // true while there are more solutions
   bool completed;

   // count how many generated
   int generated;

   // get current and compute next combination
   combination_t next()
   {
       combination_t ret = curr;

       // find what to increment
       completed = true;
       for (int i = R - 1; i >= 0; --i)
           if (curr[i] < N - R + i + 1)
           {
               int j = curr[i] + 1;
               while (i <= R-1)
                   curr[i++] = j++;
               completed = false;
               ++generated;
               break;
           }

       return ret;
   }

private:

   int N, R;
   combination_t curr;
};

int main(int argc, char **argv)
{
    int N = argc >= 2 ? atoi(argv[1]) : 5;
    int R = argc >= 3 ? atoi(argv[2]) : 2;
    combinations cs(N, R);
    while (!cs.completed)
    {
        combinations::combination_t c = cs.next();
        copy(c.begin(), c.end(), ostream_iterator<int>(cout, ","));
        cout << endl;
    }
    return cs.generated;
}

test output:

1,2,
1,3,
1,4,
1,5,
2,3,
2,4,
2,5,
3,4,
3,5,
4,5,

Select just column_name from information schema and put the result of this query into variable. Then test the variable to decide if table needs alteration or not.

P.S. Don't foget to specify TABLE_SCHEMA for COLUMNS table as well.

In windows 7, 8, and 10 you can find at the following location

C:\Users\<user>\AppData\Roaming\Subversion

If you enter the following in the Windows Explorer address bar, it will take you right there.

%appdata%\Subversion

It only seems to because that is what it is printing out. But actually, you shouldn't write the logic this way. This is equivalent:

insert into errortable (dateupdated, table1id)
    values (sysdate, 1083);

It seems silly to convert the system date to a string just to convert it back to a date.

If you want to see the full date, then you can do:

select TO_CHAR(dateupdated, 'YYYY-MM-DD HH24:MI:SS'), table1id
from errortable;

With a single with block, you can search and replace your text:

with open('file.txt','r+') as f:
    filedata = f.read()
    filedata = filedata.replace('abc','xyz')
    f.truncate(0)
    f.write(filedata)

I'm aware this is not a fast solution. Posting as hopefully easier to understand slow solution.

 public static long largestPrimeFactor(long n) {

        // largest composite factor must be smaller than sqrt
        long sqrt = (long)Math.ceil(Math.sqrt((double)n));

        long largest = -1;

        for(long i = 2; i <= sqrt; i++) {
            if(n % i == 0) {
                long test = largestPrimeFactor(n/i);
                if(test > largest) {
                    largest = test;
                }
            }
        }

        if(largest != -1) {
            return largest;
        }

        // number is prime
        return n;
    } 

select right(rtrim('94342KMR'),3)

This will fetch the last 3 right string.

select substring(rtrim('94342KMR'),1,len('94342KMR')-3)

This will fetch the remaining Characters.

With EL 2 (Expression Language 2) you can use this type of construct for your question:

    #{formatBean.format(myBean.birthdate)}

Or you can add an alternate getter in your bean resulting in

    #{myBean.birthdateString}

where getBirthdateString returns the proper text representation. Remember to annotate the get method as @Transient if it is an Entity.

I seem to be able to get along with simply:

$gpg <path_to_file>

Which outputs like this:

$ gpg /tmp/keys/something.asc 
  pub  1024D/560C6C26 2014-11-26 Something <[email protected]>
  sub  2048g/0C1ACCA6 2014-11-26

The op didn't specify in particular what key info is relevant. This output is all I care about.

Use the Take method:

var foo = (from t in MyTable
           select t.Foo).Take(10);

In VB LINQ has a take expression:

Dim foo = From t in MyTable _
          Take 10 _
          Select t.Foo

From the documentation:

Take<TSource> enumerates source and yields elements until count elements have been yielded or source contains no more elements. If count exceeds the number of elements in source, all elements of source are returned.

Just try

var file = $("#uploadedfile").prop("files")[0];
var fileName = file.name;
var fileSize = file.size;
alert("Uploading: "+fileName+" @ "+fileSize+"bytes");

It worked for me

I suspect you can adjust your approach a little and use something along the lines of the example here:

https://www.typescriptlang.org/docs/handbook/advanced-types.html#user-defined-type-guards

function isFish(pet: Fish | Bird): pet is Fish {
  return (pet as Fish).swim !== undefined;
}

I'm sure this will be an unpopular answer, but it works...

ProducerDTO[] p = new ProducerDTO[1];
producersProcedureActive
            .stream()
            .filter(producer -> producer.getPod().equals(pod))
            .findFirst()
            .ifPresent(producer -> {producersProcedureActive.remove(producer); p[0] = producer;}

p[0] will either hold the found element or be null.

The "trick" here is circumventing the "effectively final" problem by using an array reference that is effectively final, but setting its first element.

For simple example,
http://www.helloandroid.com/tutorials/how-download-fileimage-url-your-device

You will have to use httpClient and download the image (cache it if required) ,

solution offered for displaying images in listview, essentially same code(check the code where imageview is set from url) for displaying.

Lazy load of images in ListView

You can try using the Awaitility library. It makes it easy to test the systems you're talking about.

Maybe you should look at $.ajax() instead (if you are using jQuery, which it looks like). Take a look at: http://docs.jquery.com/Ajax/jQuery.ajax#options and the option "cache".

Another approach would be to look at how you cache things on the server side.

Try this, if enter key was pressed you can capture it like this for example, I developed an answer the other day html button specify selected, see if this helps.

Specify the forms name as for example yourFormName then you should be able to submit the form without having focus on the form.

document.onkeypress = keyPress;

function keyPress(e){
  var x = e || window.event;
  var key = (x.keyCode || x.which);
  if(key == 13 || key == 3){
   //  myFunc1();
   document.yourFormName.submit();
  }
}

I like to know where does we use Native Methods

Ideally, not at all. In reality some functionality is not available in Java and you have to call some C code.

The methods are implemented in C code.

I have created simple demo class for your better reference.

FirstActivity.java

 public class FirstActivity extends AppCompatActivity {

    private static final String TAG = FirstActivity.class.getSimpleName();
    private static final int REQUEST_CODE = 101;
    private Button btnMoveToNextScreen;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btnMoveToNextScreen = (Button) findViewById(R.id.btnMoveToNext);
        btnMoveToNextScreen.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent mIntent = new Intent(FirstActivity.this, SecondActivity.class);
                startActivityForResult(mIntent, REQUEST_CODE);
            }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if(resultCode == RESULT_OK){
            if(requestCode == REQUEST_CODE && data !=null) {
                String strMessage = data.getStringExtra("keyName");
                Log.i(TAG, "onActivityResult: message >>" + strMessage);
            }
        }

    }
}

And here is SecondActivity.java

public class SecondActivity extends AppCompatActivity {

    private static final String TAG = SecondActivity.class.getSimpleName();
    private Button btnMoveToPrevious;
    private EditText editText;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);

        editText = (EditText) findViewById(R.id.editText);

        btnMoveToPrevious = (Button) findViewById(R.id.btnMoveToPrevious);
        btnMoveToPrevious.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                String message = editText.getEditableText().toString();

                Intent mIntent = new Intent();
                mIntent.putExtra("keyName", message);
                setResult(RESULT_OK, mIntent);
                finish();

            }
        });

    }
}

friends: if you retrieve de data from a DB: you can call this $registers = *_num_rows( Result_query ) then

<select size=<?=$registers + 1; ?>"> 

For me neither the MouseClick or Click event worked, because the events, simply, are not called when you right click. The quick way to do it is:

 private void button1_MouseUp(object sender, MouseEventArgs e)
 {
        if (e.Button == MouseButtons.Right)
        {
            //do something here
        }
        else//left or middle click
        {
            //do something here
        }
 }

You can modify that to do exactly what you want depended on the arguments' values.

WARNING: There is one catch with only using the mouse up event. if you mousedown on the control and then you move the cursor out of the control to release it, you still get the event fired. In order to avoid that, you should also make sure that the mouse up occurs within the control in the event handler. Checking whether the mouse cursor coordinates are within the control's rectangle before you check the buttons will do it properly.

A simple solution is to restart the service when the system stops it.

Have you considered using span instead of div? It is the in-line version of div.

I just checked the status of the response object:

$promise.then( function successCallback(response) {  
  console.log(response);
  if (response.status === 200) { ... }
});

Another way of doing this, using only JavaScript, would be this:

window.addEventListener('resize', functionName);

This fires every time the size changes, like the other answer.

functionName is the name of the function being executed when the window is resized (the brackets on the end aren't necessary).

You can also use CygWin and install the cURL package. It works very well and flawlessly!!

They may look a bit different from normal HTML, but : and @ are valid chars for attribute names and all Vue.js supported browsers can parse it correctly. In addition, they do not appear in the final rendered markup. The shorthand syntax is totally optional, but you will likely appreciate it when you learn more about its usage later.

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.

This is why I wrote Picky: http://picky.readthedocs.io/

It's a python package that tracks packages installed with either pip or conda in either virtualenvs and conda envs.

Some Theory

$ is the name of a function like any other name you give to a function. Anyone can create a function in JavaScript and name it $ as shown below:

$ = function() { 
        alert('I am in the $ function');
    }

JQuery is a very famous JavaScript library and they have decided to put their entire framework inside a function named jQuery. To make it easier for people to use the framework and reduce typing the whole word jQuery every single time they want to call the function, they have also created an alias for it. That alias is $. Therefore $ is the name of a function. Within the jQuery source code, you can see this yourself:

window.jQuery = window.$ = jQuery;

Answer To Your Question

So what is $(function() { });?

Now that you know that $ is the name of the function, if you are using the jQuery library, then you are calling the function named $ and passing the argument function() {} into it. The jQuery library will call the function at the appropriate time. When is the appropriate time? According to jQuery documentation, the appropriate time is once all the DOM elements of the page are ready to be used.

The other way to accomplish this is like this:

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

As you can see this is more verbose so people prefer $(function() { })

So the reason why some functions cannot be called, as you have noticed, is because those functions do not exist yet. In other words the DOM has not loaded yet. But if you put them inside the function you pass to $ as an argument, the DOM is loaded by then. And thus the function has been created and ready to be used.

Another way to interpret $(function() { }) is like this:

Hey $ or jQuery, can you please call this function I am passing as an argument once the DOM has loaded?

I have also read that for some servers one for example needs only annotate persistence contexts, but in some servers, the injection should be done manually.

You could mess with the margins: http://jsfiddle.net/zV2p4/

But you would probably be better off using position: absolute. This does not change display: block, but it will make the width auto. To fix this, make the divs width: 100%

Try to rebase your local master branch onto your remote/origin master branch and resolve any conflicts in the process.

"Curly Braces" are used in Python to define a dictionary. A dictionary is a data structure that maps one value to another - kind of like how an English dictionary maps a word to its definition.

Python:

dict = {
    "a" : "Apple",
    "b" : "Banana",
}

They are also used to format strings, instead of the old C style using %, like:

ds = ['a', 'b', 'c', 'd']
x = ['has_{} 1'.format(d) for d in ds]

print x

['has_a 1', 'has_b 1', 'has_c 1', 'has_d 1']

They are not used to denote code blocks as they are in many "C-like" languages.

C:

if (condition) {
    // do this
}

A problem I had on my Mac using rbenv was that when I first set it up, it loaded a bunch of ruby executables in /usr/local/bin - these executables loaded the system ruby, rather than the current version.

If you run

which bundle

And it shows /usr/local/bin/bundle you may have this issue.

Search through /usr/local/bin and delete any files that start with #!/user/bin ruby

Then run

rbenv rehash

Declaration in config/app.php under aliases:-

'Input' => Illuminate\Support\Facades\Input::class,

Or You can import Input facade directly as required,

use Illuminate\Support\Facades\Input;

or

use Illuminate\Support\Facades\Input as input;

If the object is actually a Boolean instance, then just cast it:

boolean di = (Boolean) someObject;

The explicit cast will do the conversion to Boolean, and then there's the auto-unboxing to the primitive value. Or you can do that explicitly:

boolean di = ((Boolean) someObject).booleanValue();

If someObject doesn't refer to a Boolean value though, what do you want the code to do?

Try:

int[][] multD = new int[5][10];

Note that in your code only the first line of the 2D array is initialized to 0. Line 2 to 5 don't even exist. If you try to print them you'll get null for everyone of them.

RUn the following query to find if you are running spfile or not:

SELECT DECODE(value, NULL, 'PFILE', 'SPFILE') "Init File Type" 
       FROM sys.v_$parameter WHERE name = 'spfile';

If the result is "SPFILE", then use the following command:

alter system set open_cursors = 4000 scope=both; --4000 is the number of open cursor

if the result is "PFILE", then use the following command:

alter system set open_cursors = 1000 ;

You can read about SPFILE vs PFILE here,

http://www.orafaq.com/node/5

As the other answers have indicated, you need to use an anonymous type.

As far as syntax is concerned, I personally far prefer method chaining. The method chaining equivalent would be:-

var employee = _db.EMPLOYEEs
    .Where(x => x.EMAIL == givenInfo || x.USER_NAME == givenInfo)
    .Select(x => new { x.EMAIL, x.ID });

AFAIK, the declarative LINQ syntax is converted to a method call chain similar to this when it is compiled.

UPDATE

If you want the entire object, then you just have to omit the call to Select(), i.e.

var employee = _db.EMPLOYEEs
    .Where(x => x.EMAIL == givenInfo || x.USER_NAME == givenInfo);

To resolve the issue on a Debian/Ubuntu system modify the /etc/apache2/ports.conf settings file by adding NameVirtualHost *:443 to it. My ports.conf is the following at the moment:

# /etc/apache/ports.conf
# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default
# This is also true if you have upgraded from before 2.2.9-3 (i.e. from
# Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and
# README.Debian.gz

NameVirtualHost *:80
Listen 80

<IfModule mod_ssl.c>
    # If you add NameVirtualHost *:443 here, you will also have to change
    # the VirtualHost statement in /etc/apache2/sites-available/default-ssl
    # to <VirtualHost *:443>
    # Server Name Indication for SSL named virtual hosts is currently not
    # supported by MSIE on Windows XP.

    NameVirtualHost *:443

    Listen 443
</IfModule>

<IfModule mod_gnutls.c>
    NameVirtualHost *:443
    Listen 443
</IfModule>

Furthermore ensure that 'sites-available/default-ssl' is not enabled, type a2dissite default-ssl to disable the site. While you're at it type a2dissite by itself to get a list and see if there is any other site settings that you have enabled that might be mapping onto port 443.

From Java 9, you can use the stream provided by Matcher.results()

long matches = matcher.results().count();

You haven't at time of writing described what you are going to do with the response or what its content type is. An answer already contains a very basic usage of MSXML2.XMLHTTP (I recommend the more explicit MSXML2.XMLHTTP.3.0 progID) however you may need to do different things with the response, it may not be text.

The XMLHTTP also has a responseBody property which is a byte array version of the reponse and there is a responseStream which is an IStream wrapper for the response.

Note that in a server-side requirement (e.g., VBScript hosted in ASP) you would use MSXML.ServerXMLHTTP.3.0 or WinHttp.WinHttpRequest.5.1 (which has a near identical interface).

Here is an example of using XmlHttp to fetch a PDF file and store it:-

Dim oXMLHTTP
Dim oStream

Set oXMLHTTP = CreateObject("MSXML2.XMLHTTP.3.0")

oXMLHTTP.Open "GET", "http://someserver/folder/file.pdf", False
oXMLHTTP.Send

If oXMLHTTP.Status = 200 Then
    Set oStream = CreateObject("ADODB.Stream")
    oStream.Open
    oStream.Type = 1
    oStream.Write oXMLHTTP.responseBody
    oStream.SaveToFile "c:\somefolder\file.pdf"
    oStream.Close
End If

I used this:

                              myElement = document.getElemenById("xyz");
Get_Offset_From_Start       ( myElement );  // returns positions from website's start position
Get_Offset_From_CurrentView ( myElement );  // returns positions from current scrolled view's TOP and LEFT

code:

function Get_Offset_From_Start (object, offset) { 
    offset = offset || {x : 0, y : 0};
    offset.x += object.offsetLeft;       offset.y += object.offsetTop;
    if(object.offsetParent) {
        offset = Get_Offset_From_Start (object.offsetParent, offset);
    }
    return offset;
}

function Get_Offset_From_CurrentView (myElement) {
    if (!myElement) return;
    var offset = Get_Offset_From_Start (myElement);
    var scrolled = GetScrolled (myElement.parentNode);
    var posX = offset.x - scrolled.x;   var posY = offset.y - scrolled.y;
    return {lefttt: posX , toppp: posY };
}
//helper
function GetScrolled (object, scrolled) {
    scrolled = scrolled || {x : 0, y : 0};
    scrolled.x += object.scrollLeft;    scrolled.y += object.scrollTop;
    if (object.tagName.toLowerCase () != "html" && object.parentNode) { scrolled=GetScrolled (object.parentNode, scrolled); }
    return scrolled;
}

    /*
    // live monitoring
    window.addEventListener('scroll', function (evt) {
        var Positionsss =  Get_Offset_From_CurrentView(myElement);  
        console.log(Positionsss);
    });
    */

you can solve this, taking the input tag inside a div, then put the padding property on div tag. This work's for me...

Like this:

<div class="paded">
    <input type="text" />
</div>

and css:

.paded{
    padding-right: 20px;
}

long millisecond = beginupd.getTime();

Date.getTime() JavaDoc states:

Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object.

First add a variable to your SSIS package (Package Scope) - I used FileName, OleRootFilePath, OleProperties, OleProvider. The type for each variable is "string". Then I create a Configuration file (Select each variable - value) - populate the values in the configuration file - Eg: for OleProperties - Microsoft.ACE.OLEDB.12.0; for OleProperties - Excel 8.0;HDR=, OleRootFilePath - Your Excel file path, FileName - FileName

In the Connection manager - I then set the Properties-> Expressions-> Connection string expression dynamically eg:

"Provider=" + @[User::OleProvider] + "Data Source=" + @[User::OleRootFilePath]
+ @[User::FileName]  + ";Extended Properties=\"" + @[User::OleProperties] + "NO \""+";"

This way once you set the variables values and change it in your configuration file - the connection string will change dynamically - this helps especially in moving from development to production environments.

You may have a table called 'test'

COPY test(gid, "name", the_geom)
FROM '/home/data/sample.csv'
WITH DELIMITER ','
CSV HEADER

//Disable a search on particular selector
$(".my_selector").select2({
    placeholder: "ÁREAS(todas)",
    tags: true,
    width:'100%',
    containerCssClass: "area_disable_search_input" // I add new class 
});

//readonly prop to selector class
$(".area_disable_search_input input").prop("readonly", true);

I think this will work for you. But visitors are easy if they got something in seconds without spending more time and hence they will also again visit your site. <a href="file.zip" onclick="if (event.button==0) setTimeout(function(){document.body.innerHTML='thanks!'},500)"> Start automatic download! </a>

Swift 3
Set number of lines zero for dynamic text information, it will be useful for varying text.

var label = UILabel()
let stringValue = "A label\nwith\nmultiline text."
label.text = stringValue
label.numberOfLines = 0
label.lineBreakMode = .byTruncatingTail // or .byWrappingWord
label.minimumScaleFactor = 0.8 . // It is not required but nice to have a minimum scale factor to fit text into label frame

I use the AbsoluteUri and you can get it like this:

string myURI = Request.Url.AbsoluteUri;
 if (!WebSecurity.IsAuthenticated) {
        Response.Redirect("~/Login?returnUrl="
            + Request.Url.AbsoluteUri );

Then after you login:

var returnUrl = Request.QueryString["returnUrl"];
 if(WebSecurity.Login(username,password,true)){
                Context.RedirectLocal(returnUrl);

It works well for me.

Write your regex differently:

var r = /^a$/;
r.test('a'); // true
r.test('ba'); // false

First - I have to direct you to http://www.angelikalanger.com/GenericsFAQ/JavaGenericsFAQ.html -- she does an amazing job.

The basic idea is that you use

<T extends SomeClass>

when the actual parameter can be SomeClass or any subtype of it.

In your example,

Map<String, Class<? extends Serializable>> expected = null;
Map<String, Class<java.util.Date>> result = null;
assertThat(result, is(expected));

You're saying that expected can contain Class objects that represent any class that implements Serializable. Your result map says it can only hold Date class objects.

When you pass in result, you're setting T to exactly Map of String to Date class objects, which doesn't match Map of String to anything that's Serializable.

One thing to check -- are you sure you want Class<Date> and not Date? A map of String to Class<Date> doesn't sound terribly useful in general (all it can hold is Date.class as values rather than instances of Date)

As for genericizing assertThat, the idea is that the method can ensure that a Matcher that fits the result type is passed in.

I hope this will help to you.

I suspect you will be able to import 1 GB file through phpmyadmin But you can try by increasing the following value in php.ini and restart the wamp.

post_max_size=1280M
upload_max_filesize=1280M
max_execution_time = 300 //increase time as per your server requirement. 

You can also try below command from command prompt, your path may be different as per your MySQL installation.

C:\wamp\bin\mysql\mysql5.5.24\bin\mysql.exe -u root -p db_name < C:\some_path\your_sql_file.sql

You should increase the max_allowed_packet of mysql in my.ini to avoid MySQL server gone away error, something like this

max_allowed_packet = 100M

You can't get a path to file from WhatsApp. They don't expose it now. The only thing you can get is InputStream:

InputStream is = getContentResolver().openInputStream(Uri.parse("content://com.whatsapp.provider.media/item/16695"));

Using is you can show a picture from WhatsApp in your app.

Simply use the .rules('add') method immediately after creating the element...

var filenumber = 1;
$("#AddFile").click(function () { //User clicks button #AddFile

    // create the new input element
    $('<li><input type="file" name="FileUpload' + filenumber + '" id="FileUpload' + filenumber + '" /> <a href="#" class="RemoveFileUpload">Remove</a></li>').prependTo("#FileUploader");

    // declare the rule on this newly created input field        
    $('#FileUpload' + filenumber).rules('add', {
        required: true,  // <- with this you would not need 'required' attribute on input
        accept: "image/jpeg, image/pjpeg"
    });

    filenumber++; // increment counter for next time

    return false;
});

• You'll still need to use .validate() to initialize the plugin within a DOM ready handler.

• You'll still need to declare rules for your static elements using .validate(). Whatever input elements that are part of the form when the page loads... declare their rules within .validate().

• You don't need to use .each(), when you're only targeting ONE element with the jQuery selector attached to .rules().

• You don't need the required attribute on your input element when you're declaring the required rule using .validate() or .rules('add'). For whatever reason, if you still want the HTML5 attribute, at least use a proper format like required="required".

Working DEMO: http://jsfiddle.net/8dAU8/5/

My solution for a cache implementation that stores optional NSAttributedString:

public static var attributedMessageTextCache    = [String: NSAttributedString?]()

    if attributedMessageTextCache.index(forKey: "key") != nil
    {
        if let attributedMessageText = TextChatCache.attributedMessageTextCache["key"]
        {
            return attributedMessageText
        }
        return nil
    }

    TextChatCache.attributedMessageTextCache["key"] = .some(.none)
    return nil

In your R script, called test.R:

args <- commandArgs(trailingOnly = F)
myargument <- args[length(args)]
myargument <- sub("-","",myargument)
print(myargument)
q(save="no")

From the command line run:

R CMD BATCH -4 test.R

Your output file, test.Rout, will show that the argument 4 has been successfully passed to R:

cat test.Rout

> args <- commandArgs(trailingOnly = F)
> myargument <- args[length(args)]
> myargument <- sub("-","",myargument)
> print(myargument)
[1] "4"
> q(save="no")
> proc.time()
user  system elapsed 
0.222   0.022   0.236 

You have an error in your code. This line:

for(int i=0;i<v[n];i++)

should be

for(int i=0;i<n;i++)

because you want to search n places in your vector, not v[n] places (which wouldn't mean anything)

There's a I/O library available, but if it's available depends on your scripting host (assuming you've embedded lua somewhere). It's available, if you're using the command line version. The complete I/O model is most likely what you're looking for.

You can convert yourInt to bytes by using a ByteBuffer like this:

return ByteBuffer.allocate(4).putInt(yourInt).array();

Beware that you might have to think about the byte order when doing so.

You can use the DataFrame method .apply() to operate on the values in Mycol:

>>> df = pd.DataFrame(['05SEP2014:00:00:00.000'],columns=['Mycol'])
>>> df
                    Mycol
0  05SEP2014:00:00:00.000
>>> import datetime as dt
>>> df['Mycol'] = df['Mycol'].apply(lambda x: 
                                    dt.datetime.strptime(x,'%d%b%Y:%H:%M:%S.%f'))
>>> df
       Mycol

It is a non-standard CSS, which is not covered in current version of CSS (Firefox does not support it). Try to use JavaScript instead.

As people have mentioned in the comments keyvalue pipe does not retain the order of insertion (which is the primary purpose of Map).

Anyhow, looks like if you have a Map object and want to preserve the order, the cleanest way to do so is entries() function:

<ul>
    <li *ngFor="let item of map.entries()">
        <span>key: {{item[0]}}</span>
        <span>value: {{item[1]}}</span>
    </li>
</ul>

str() is the equivalent.

However you should be filtering your query. At the moment your query is all() Todo's.

todos = Todo.all().filter('author = ', users.get_current_user().nickname()) 

or

todos = Todo.all().filter('author = ', users.get_current_user())

depending on what you are defining author as in the Todo model. A StringProperty or UserProperty.

Note nickname is a method. You are passing the method and not the result in template values.

I've resolved this using:

.element:before {
    font-family: "Font Awesome 5 Free" , "CircularStd";
    content: "\f017" " Date";
}

Using the font family "font awesome 5 free" for the icon, and after, We have to specify the font that we are using again because if we doesn't do this, navigator will use the default font (times new roman or something like this).

public int this[int index]
{
    get => values[index];
}

it's worth noting that the Win32_Product WMI class represents products as they are installed by Windows Installer. not every application use windows installer

however "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" represents applications for 32 bit. For 64 bit you also need to traverse "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" and since not every software has a 64 bit version the total applications installed are a union of keys on both locations that have "UninstallString" Value with them.

but the best options remains the same .traverse registry keys is a better approach since every application have an entry in registry[including the ones in Windows Installer].however the registry method is insecure as if anyone removes the corresponding key then you will not know the Application entry.On the contrary Altering the HKEY_Classes_ROOT\Installers is more tricky as it is linked with licensing issues such as Microsoft office or other products. for more robust solution you can always combine registry alternative with the WMI.

The only good way I found was to use Javascript to move a tooltip <div> around. Obviously this only works if you have SVG inside an HTML document - not standalone. And it requires Javascript.

function showTooltip(evt, text) {_x000D_
  let tooltip = document.getElementById("tooltip");_x000D_
  tooltip.innerHTML = text;_x000D_
  tooltip.style.display = "block";_x000D_
  tooltip.style.left = evt.pageX + 10 + 'px';_x000D_
  tooltip.style.top = evt.pageY + 10 + 'px';_x000D_
}_x000D_
_x000D_
function hideTooltip() {_x000D_
  var tooltip = document.getElementById("tooltip");_x000D_
  tooltip.style.display = "none";_x000D_
}

#tooltip {_x000D_
  background: cornsilk;_x000D_
  border: 1px solid black;_x000D_
  border-radius: 5px;_x000D_
  padding: 5px;_x000D_
}

<div id="tooltip" display="none" style="position: absolute; display: none;"></div>_x000D_
_x000D_
<svg>_x000D_
  <rect width="100" height="50" style="fill: blue;" onmousemove="showTooltip(evt, 'This is blue');" onmouseout="hideTooltip();" >_x000D_
  </rect>_x000D_
</svg>

called_from must be null. Add a test against that condition like

if (called_from != null && called_from.equalsIgnoreCase("add")) {

or you could use Yoda conditions (per the Advantages in the linked Wikipedia article it can also solve some types of unsafe null behavior they can be described as placing the constant portion of the expression on the left side of the conditional statement)

if ("add".equalsIgnoreCase(called_from)) { // <-- safe if called_from is null

You can't - globally, i.e. for every python program. And this is a good thing - Python is great for scripting (automating stuff), and scripts should be able to run without any user interaction at all.

However, you can always ask for input at the end of your program, effectively keeping the program alive until you press return. Use input("prompt: ") in Python 3 (or raw_input("promt: ") in Python 2). Or get used to running your programs from the command line (i.e. python mine.py), the program will exit but its output remains visible.

First error: You're casting a ClientThread as a String for some reason.

Second error: You're not calling remove on your List.

Is is homework? If so, you might want to use the tag.

You should also consider the OPTIMIZE FOR n ROWS clause. More details on all of this in the DB2 LUW documentation in the Guidelines for restricting SELECT statements topic:

• The OPTIMIZE FOR clause declares the intent to retrieve only a subset of the result or to give priority to retrieving only the first few rows. The optimizer can then choose access plans that minimize the response time for retrieving the first few rows.

I think this is the shortest SQL statement for that:

CREATE FUNCTION [dbo].[fn_stripsingleQuote] (@strStrip varchar(Max))
    RETURNS varchar(Max)
AS
BEGIN    
    RETURN (Replace(@strStrip ,'''',''))
END

I hope this helps!

It's calling the files included in that particular bundle which is declared inside the BundleConfig class in the App_Start folder.

In that particular case The call to @Styles.Render("~/Content/css") is calling "~/Content/site.css".

It's likely that someone else (e.g. your colleague) has put commits onto origin/master that aren't in your local master branch, and you are trying to push some commits from your local branch to the server. In 99% of cases, assuming you don't want to erase their work from origin, you have two options:

2) Merge their changes into your local branch, and then push the merged result. git checkout master git pull # resolve conflicts here git push

(Note that git pull is essentially just a git fetch and a git merge in this case.)

1) Rebase your local branch, so that it looks like your colleague made their commits first, and then you made your commits. This keeps the commit history nice and linear - and avoids a "merge commit". However, if you have conflicts with your colleague's changes, you may have to resolve those conflicts for each of your commits (rather than just once) in the worst case. Essentially this is nicer for everyone else but more effort for you. git pull --rebase # resolve conflicts here git push

(Note that git pull --rebase is essentially a git fetch and a git rebase origin/master.)

Example: http://xxjjnn.com/linktablerow.html

Link entire row:

<table>
  <tr onclick="location.href='SomeWherrrreOverTheWebsiiiite.html'">**
    <td> ...content... </td>
    <td> ...content... </td>
    ...
  </tr>
</table>

Iff you'd like to do highlight on mouseover for the entire row, then:

<table class="nogap">
  <tr class="lovelyrow" onclick="location.href='SomeWherrrreOverTheWebsiiiite.html'">**
     ...
  </tr>
</table>

with something like the following for css, which will remove the gap between the table cells and change the background on hover:

tr.lovelyrow{
  background-color: hsl(0,0%,90%);
}

tr.lovelyrow:hover{
  background-color: hsl(0,0%,40%);
  cursor: pointer;
}

table.nogap{
  border-collapse: collapse;
}

Iff you are using Rails 3.0.9 then you might find this example code useful:

  <tr onclick="location.href='<%= sea_fish_scales_path(@sea, fish) %>'"> 
    <td><%= fish.title %></td>
  </tr>
<% end %>
</table>

with @fishies and @sea are defined in app/controllers/seas_controller.rb

You change default value in MySQL configuration file (option connect_timeout in mysqld section) -

[mysqld]
connect_timeout=100

If this file is not accessible for you, then you can set this value using this statement -

SET GLOBAL connect_timeout=100;

The FileUpload.AllowMultiple property in .NET 4.5 and higher will allow you the control to select multiple files.

Below 4.5 like 4.0(vs 2010) we can use jquery for multiple file upload in single control,using,2 js files: http://code.jquery.com/jquery-1.8.2.js and http://code.google.com/p/jquery-multifile-plugin/

in aspx file upload tag,add like class="multi"

<asp:FileUpload ID="FileUpload1" class="multi" runat="server" />

Here is a kind of a "functional", "one-liner" implementation. It is recursive, and based on a conditional expression and a dict comprehension.

def flatten_dict(dd, separator='_', prefix=''):
    return { prefix + separator + k if prefix else k : v
             for kk, vv in dd.items()
             for k, v in flatten_dict(vv, separator, kk).items()

Simple way to format a date and convert into string

    Date date= new Date();

    String dateStr=String.format("%td/%tm/%tY", date,date,date);

    System.out.println("Date with format of dd/mm/dd: "+dateStr);

output:Date with format of dd/mm/dd: 21/10/2015

I have a file called NewsArticle.txt on my Desktop.

In Spark, I typed:

val textFile= sc.textFile(“file:///C:/Users/582767/Desktop/NewsArticle.txt”)

I needed to change all the \ to / character for the filepath.

To test if it worked, I typed:

textFile.foreach(println)

I'm running Windows 7 and I don't have Hadoop installed.

This worked for me best:

$('.alert').on('close.bs.alert', function (e) {
    e.preventDefault();
    $(this).hide();
});

Image.paste does not work as expected when the background image also contains transparency. You need to use real Alpha Compositing.

Pillow 2.0 contains an alpha_composite function that does this.

background = Image.open("test1.png")
foreground = Image.open("test2.png")

Image.alpha_composite(background, foreground).save("test3.png")

EDIT: Both images need to be of the type RGBA. So you need to call convert('RGBA') if they are paletted, etc.. If the background does not have an alpha channel, then you can use the regular paste method (which should be faster).

1) How do I make it so that the whole column is "checked" by default?

var doWork = new DataGridViewCheckBoxColumn();
doWork.Name = "IncludeDog" //Added so you can find the column in a row
doWork.HeaderText = "Include Dog";
doWork.FalseValue = "0";
doWork.TrueValue = "1";

//Make the default checked
doWork.CellTemplate.Value = true;
doWork.CellTemplate.Style.NullValue = true;

dataGridView1.Columns.Insert(0, doWork);

2) How can I make sure I'm only getting values from the "checked" rows?

foreach (DataGridViewRow row in dataGridView1.Rows)
{
    if (row.IsNewRow) continue;//If editing is enabled, skip the new row

    //The Cell's Value gets it wrong with the true default, it will return         
    //false until the cell changes so use FormattedValue instead.
    if (Convert.ToBoolean(row.Cells["IncludeDog"].FormattedValue))
    {
        //Do stuff with row
    }
}

You should know the PID of your process.

When you launch it, its PID will be recorded in the $! variable. Save this PID into a file.

Then you will need to check if this PID corresponds to a running process. Here's a complete skeleton script:

FILE="/tmp/myapp.pid"

if [ -f $FILE ];
then
   PID=$(cat $FILE)
else
   PID=1
fi

ps -o pid= -p $PID
if [ $? -eq 0 ]; then
  echo "Process already running."  
else
  echo "Starting process."
  run_my_app &
  echo $! > $FILE
fi

Based on the answer of peterh. The trick for knowing if a given PID is running is in the ps -o pid= -p $PID instruction.

You can also done this by using group by clause

   SELECT purchases.address_id, purchases.* FROM "purchases"
    WHERE "purchases"."product_id" = 1 GROUP BY address_id,
purchases.purchased_at ORDER purchases.purchased_at DESC

That depends. Is it just a variable (in a method)? Or a class-member?

If it's just a variable you'll get an error that no value has been set when trying to read from it without first assinging it a value.

If it's a class-member it will be initialized to null by the VM.

If you are using IntelliJ IDE just right click on resources package and go to new and then select Resource Boundle it automatically create a .properties file for you. This did work for me .

float(str(round(answer, 2)))
float(str(round(0.0556781255, 2)))

NSDate *currentDate = [NSDate date];
NSDateComponents *comps = [[NSDateComponents alloc] init];
[comps setHour:10];
NSDate *date = [gregorian dateByAddingComponents:comps toDate:currentDate  options:0];
[comps release];

Not tested in xcode though :)

You can just iterate over the data attributes like any other object to get keys and values, here's how to do it with $.each:

    $.each($('#myEl').data(), function(key, value) {
        console.log(key);
        console.log(value);
    });

DECLARE @MinDate DATETIME = '2012-09-23 00:02:00.000',
    @MaxDate DATETIME = '2012-09-25 00:00:00.000';

SELECT  TOP (DATEDIFF(DAY, @MinDate, @MaxDate) + 1) Dates = DATEADD(DAY, ROW_NUMBER() OVER(ORDER BY a.object_id) - 1, @MinDate)
FROM sys.all_objects a CROSS JOIN sys.all_objects b;

You might be just missing the column list, as the message says

SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] ON

INSERT INTO [MyDB].[dbo].[Equipment]
            (COL1,
             COL2)
SELECT COL1,
       COL2
FROM   [MyDBQA].[dbo].[Equipment]

SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] OFF 

I had a similar error with the following code:-

foreach($myvar as $key => $value){
    $query = "SELECT stuff
            FROM table
            WHERE col1 = '$criteria1'
            AND col2 = '$criteria2'";

    $result = mysql_query($query) or die('Could not execute query - '.mysql_error(). __FILE__. __LINE__. $query);               
    $point_values = mysql_fetch_assoc($result);
    $top_five_actions[$key] += $point_values; //<--- Problem Line       
}

It turned out that my $point_values variable was occasionally returning false which caused the problem so I fixed it by wrapping it in mysql_num_rows check:-

if(mysql_num_rows($result) > 0) {
        $point_values = mysql_fetch_assoc($result);
        $top_five_actions[$key] += $point_values;
}

Not sure if this helps though?

Cheers

The accepted answer works, but I don't like much the idea to paste secure tokens into the package.json

I have found it elsewhere, just run this one-time command as documented in the git-config manpage.

git config --global url."https://${GITHUB_TOKEN}@github.com/".insteadOf [email protected]:

GITHUB_TOKEN may be setup as environmnet variable or pasted directly

and then I install private github repos like: npm install user/repo --save

works also in Heroku, just setup the above git config ... command as heroku-prebuild script in package.json and setup GITHUB_TOKEN as Heroku config variable.

I normally just run git mergetool and it will prompt me if I want to keep the modified file or keep it deleted. This is the quickest way IMHO since it's one command instead of several per file.

If you have a bunch of deleted files in a specific subdirectory and you want all of them to be resolved by deleting the files, you can do this:

yes d | git mergetool -- the/subdirectory

The d is provided to choose deleting each file. You can also use m to keep the modified file. Taken from the prompt you see when you run mergetool:

Use (m)odified or (d)eleted file, or (a)bort?

There is boolean data type in SQL Server. Its values can be TRUE, FALSE or UNKNOWN. However, the boolean data type is only the result of a boolean expression containing some combination of comparison operators (e.g. =, <>, <, >=) or logical operators (e.g. AND, OR, IN, EXISTS). Boolean expressions are only allowed in a handful of places including the WHERE clause, HAVING clause, the WHEN clause of a CASE expression or the predicate of an IF or WHILE flow control statement.

For all other usages, including the data type of a column in a table, boolean is not allowed. For those other usages, the BIT data type is preferred. It behaves like a narrowed-down INTEGER which allows only the values 0, 1 and NULL, unless further restricted with a NOT NULL column constraint or a CHECK constraint.

To use a BIT column in a boolean expression it needs to be compared using a comparison operator such as =, <> or IS NULL. e.g.

SELECT
    a.answer_body
FROM answers AS a
WHERE a.is_accepted = 0;

From a formatting perspective, a bit value is typically displayed as 0 or 1 in client software. When a more user-friendly format is required, and it can't be handled at an application tier in front of the database, it can be converted "just-in-time" using a CASE expression e.g.

SELECT
    a.answer_body,
    CASE a.is_accepted WHEN 1 THEN 'TRUE' ELSE 'FALSE' END AS is_accepted
FROM answers AS a;

Storing boolean values as a character data type like char(1) or varchar(5) is also possible, but that is much less clear, has more storage/network overhead, and requires CHECK constraints on each column to restrict illegal values.

For reference, the schema of answers table would be similar to:

CREATE TABLE answers (
    ...,
    answer_body nvarchar(MAX) NOT NULL,
    is_accepted bit NOT NULL DEFAULT (0)
);

While Andriy's proposal will work well for INSERTs of a small number of records, full table scans will be done on the final join as both 'enumerated' and '@new_super' are not indexed, resulting in poor performance for large inserts.

This can be resolved by specifying a primary key on the @new_super table, as follows:

DECLARE @new_super TABLE (
  row_num INT IDENTITY(1,1) PRIMARY KEY CLUSTERED,
  super_id   int
);

This will result in the SQL optimizer scanning through the 'enumerated' table but doing an indexed join on @new_super to get the new key.

If you use Guava (v11 minimum) in your project you can use Maps::transformValues.

Map<String, Column> newColumnMap = Maps.transformValues(
  originalColumnMap,
  Column::new // equivalent to: x -> new Column(x) 
)

Note: The values of this map are evaluated lazily. If the transformation is expensive you can copy the result to a new map like suggested in the Guava docs.

To avoid lazy evaluation when the returned map doesn't need to be a view, copy the returned map into a new map of your choosing.

I found the file located at:

C:\xampp\php\php.ini

Uncommented:

;extension=php_curl.dll

import AVFoundation

import AudioToolbox

public final class MP3Player : NSObject {
    
    // Singleton class
    static let shared:MP3Player = MP3Player()
    
    private var player: AVAudioPlayer? = nil
    
    // Play only mp3 which are stored in the local
    public func playLocalFile(name:String) {
        guard let url = Bundle.main.url(forResource: name, withExtension: "mp3") else { return }

        do {
            try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback)
            try AVAudioSession.sharedInstance().setActive(true)
            player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.mp3.rawValue)
            guard let player = player else { return }

            player.play()
        }catch let error{
            print(error.localizedDescription)
        }
    }
}

To call this function

MP3Player.shared.playLocalFile(name: "JungleBook")

One way would be:

import random
d = {'VENEZUELA':'CARACAS', 'CANADA':'OTTAWA'}
random.choice(list(d.values()))

EDIT: The question was changed a couple years after the original post, and now asks for a pair, rather than a single item. The final line should now be:

country, capital = random.choice(list(d.items()))

PHP has a built in function called bool chmod(string $filename, int $mode )

http://php.net/function.chmod

private function writeFileContent($file, $content){
    $fp = fopen($file, 'w');
    fwrite($fp, $content);
    fclose($fp);
    chmod($file, 0777);  //changed to add the zero
    return true;
}

Also it may cause some warnigs in logs like a Cglib2AopProxy Unable to proxy method. And many other reasons for this are described here Why always have single implementaion interfaces in service and dao layers?

I learned how to do these sort of things reading "PRO HTML and CSS Design Patterns". The display:block is the default display value for the div, but I like to make it explicit. The container has to be the right type; position attribute is fixed, relative, or absolute.

.stretchedToMargin {_x000D_
  display: block;_x000D_
  position:absolute;_x000D_
  height:auto;_x000D_
  bottom:0;_x000D_
  top:0;_x000D_
  left:0;_x000D_
  right:0;_x000D_
  margin-top:20px;_x000D_
  margin-bottom:20px;_x000D_
  margin-right:80px;_x000D_
  margin-left:80px;_x000D_
  background-color: green;_x000D_
}

<div class="stretchedToMargin">_x000D_
  Hello, world_x000D_
</div>

Fiddle by Nooshu's comment

I want to control the height of the border. How could I do this?

You can't. CSS borders will always span across the full height / width of the element.

One workaround idea would be to use absolute positioning (which can accept percent values) to place the border-carrying element inside one of the two divs. For that, you would have to make the element position: relative.

Why

There is IMHO a good reason why Composer will use the --dev flag by default (on install and update) nowadays. Composer is mostly run in scenario's where this is desired behavior:

The basic Composer workflow is as follows:

• A new project is started: composer.phar install --dev, json and lock files are commited to VCS.
• Other developers start working on the project: checkout of VCS and composer.phar install --dev.
• A developer adds dependancies: composer.phar require <package>, add --dev if you want the package in the require-dev section (and commit).
• Others go along: (checkout and) composer.phar install --dev.
• A developer wants newer versions of dependencies: composer.phar update --dev <package> (and commit).
• Others go along: (checkout and) composer.phar install --dev.
• Project is deployed: composer.phar install --no-dev

As you can see the --dev flag is used (far) more than the --no-dev flag, especially when the number of developers working on the project grows.

Production deploy

What's the correct way to deploy this without installing the "dev" dependencies?

Well, the composer.json and composer.lock file should be committed to VCS. Don't omit composer.lock because it contains important information on package-versions that should be used.

When performing a production deploy, you can pass the --no-dev flag to Composer:

composer.phar install --no-dev

The composer.lock file might contain information about dev-packages. This doesn't matter. The --no-dev flag will make sure those dev-packages are not installed.

When I say "production deploy", I mean a deploy that's aimed at being used in production. I'm not arguing whether a composer.phar install should be done on a production server, or on a staging server where things can be reviewed. That is not the scope of this answer. I'm merely pointing out how to composer.phar install without installing "dev" dependencies.

Offtopic

The --optimize-autoloader flag might also be desirable on production (it generates a class-map which will speed up autoloading in your application):

composer.phar install --no-dev --optimize-autoloader

Or when automated deployment is done:

composer.phar install --no-ansi --no-dev --no-interaction --no-plugins --no-progress --no-scripts --optimize-autoloader

If your codebase supports it, you could swap out --optimize-autoloader for --classmap-authoritative. More info here

As per matplotlib's suggestion for image grids:

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import ImageGrid

fig = plt.figure(figsize=(4., 4.))
grid = ImageGrid(fig, 111,  # similar to subplot(111)
                 nrows_ncols=(2, 2),  # creates 2x2 grid of axes
                 axes_pad=0.1,  # pad between axes in inch.
                 )

for ax, im in zip(grid, image_data):
    # Iterating over the grid returns the Axes.
    ax.imshow(im)

plt.show()

If you installed OpenCV using the opencv-python pip package at any point in time, be aware of the following note, taken from https://pypi.python.org/pypi/opencv-python

IMPORTANT NOTE MacOS and Linux wheels have currently some limitations:

• video related functionality is not supported (not compiled with FFmpeg)
• for example cv2.imshow() will not work (not compiled with GTK+ 2.x or Carbon support)

Also note that to install from another source, first you must remove the opencv-python package

I had a similar issue on 16.04 VPS Digital Ocean. If you are changing crontabs, make sure to run

In the simplest form, I think a dimension table is something like a 'Master' table - that keeps a list of all 'items', so to say.

A fact table is a transaction table which describes all the transactions. In addition, aggregated (grouped) data like total sales by sales person, total sales by branch - such kinds of tables also might exist as independent fact tables.

Generally, .c and .h files are for C or C-compatible code, everything else is C++.

Many folks prefer to use a consistent pairing for C++ files: .cpp with .hpp, .cxx with .hxx, .cc with .hh, etc. My personal preference is for .cpp and .hpp.

RFC 7396: JSON Merge Patch (published four years after the question was posted) describes the best practices for a PATCH in terms of the format and processing rules.

In a nutshell, you submit an HTTP PATCH to a target resource with the application/merge-patch+json MIME media type and a body representing only the parts that you want to be changed/added/removed and then follow the below processing rules.

Rules:

• If the provided merge patch contains members that do not appear within the target, those members are added.

• If the target does contain the member, the value is replaced.

• Null values in the merge patch are given special meaning to indicate the removal of existing values in the target.

Example test cases that illustrate the rules above (as seen in the appendix of that RFC):

Nobody mentioned that case class companion object has tupled defention, which has a type:

case class Person(name: String, age: Int)
//Person.tupled is def tupled: ((String, Int)) => Person

The only use case I can find is when you need to construct case class from tuple, example:

val bobAsTuple = ("bob", 14)
val bob = (Person.apply _).tupled(bobAsTuple) //bob: Person = Person(bob,14)

You can do the same, without tupled, by creating object directly, but if your datasets expressed as list of tuple with arity 20(tuple with 20 elements), may be using tupled is your choise.

The problem is that in IE (which is what I presume you're testing in), the <iframe> element has a document property that refers to the document containing the iframe, and this is getting used before the contentDocument or contentWindow.document properties. What you need is:

function GetDoc(x) {
    return x.contentDocument || x.contentWindow.document;
}

Also, document.all is not available in all browsers and is non-standard. Use document.getElementById() instead.

Using vmin and vmax forces the range for the colors. Here's an example:

import matplotlib as m
import matplotlib.pyplot as plt
import numpy as np

cdict = {
  'red'  :  ( (0.0, 0.25, .25), (0.02, .59, .59), (1., 1., 1.)),
  'green':  ( (0.0, 0.0, 0.0), (0.02, .45, .45), (1., .97, .97)),

If you are interested in strong exception guarantee (when copy constructor can throw an exception):

template<typename T>
inline void append_copy(std::vector<T>& v1, const std::vector<T>& v2)
{
    const auto orig_v1_size = v1.size();
    v1.reserve(orig_v1_size + v2.size());
    try
    {
        v1.insert(v1.end(), v2.begin(), v2.end());
    }
    catch(...)
    {
        v1.erase(v1.begin() + orig_v1_size, v1.end());
        throw;
    }
}

Similar append_move with strong guarantee can't be implemented in general if vector element's move constructor can throw (which is unlikely but still).

You are assigning a numeric value to a text field. You have to convert the numeric value to a string with:

String.valueOf(variable)

Combine them. Literally combine them; attach them together without any punctuation.

$('.myclass[reference="12345"]')

Your first selector looks for elements with the attribute value, contained in elements with the class.
The space is being interpreted as the descendant selector.

Your second selector, like you said, looks for elements with either the attribute value, or the class, or both.
The comma is being interpreted as the multiple selector operator — whatever that means (CSS selectors don't have a notion of "operators"; the comma is probably more accurately known as a delimiter).

import pymongo
conn = pymongo.MongoClient()

col = db.spam #Here spam is my collection
array = list(col.find())

print array

There you go

Your solution makes use of an extension to GROUP BY clause that permits to group by some fields (in this case, just post_author):

GROUP BY wp_posts.post_author

and select nonaggregated columns:

SELECT wp_posts.*

that are not listed in the group by clause, or that are not used in an aggregate function (MIN, MAX, COUNT, etc.).

Correct use of extension to GROUP BY clause

This is useful when all values of non-aggregated columns are equal for every row.

For example, suppose you have a table GardensFlowers (name of the garden, flower that grows in the garden):

INSERT INTO GardensFlowers VALUES
('Central Park',       'Magnolia'),
('Hyde Park',          'Tulip'),
('Gardens By The Bay', 'Peony'),
('Gardens By The Bay', 'Cherry Blossom');

and you want to extract all the flowers that grows in a garden, where multiple flowers grow. Then you have to use a subquery, for example you could use this:

SELECT GardensFlowers.*
FROM   GardensFlowers
WHERE  name IN (SELECT   name
                FROM     GardensFlowers
                GROUP BY name
                HAVING   COUNT(DISTINCT flower)>1);

If you need to extract all the flowers that are the only flowers in the garder instead, you could just change the HAVING condition to HAVING COUNT(DISTINCT flower)=1, but MySql also allows you to use this:

SELECT   GardensFlowers.*
FROM     GardensFlowers
GROUP BY name
HAVING   COUNT(DISTINCT flower)=1;

no subquery, not standard SQL, but simpler.

Incorrect use of extension to GROUP BY clause

But what happens if you SELECT non-aggregated columns that are non equal for every row? Which is the value that MySql chooses for that column?

It looks like MySql always chooses the FIRST value it encounters.

To make sure that the first value it encounters is exactly the value you want, you need to apply a GROUP BY to an ordered query, hence the need to use a subquery. You can't do it otherwise.

Given the assumption that MySql always chooses the first row it encounters, you are correcly sorting the rows before the GROUP BY. But unfortunately, if you read the documentation carefully, you'll notice that this assumption is not true.

When selecting non-aggregated columns that are not always the same, MySql is free to choose any value, so the resulting value that it actually shows is indeterminate.

I see that this trick to get the first value of a non-aggregated column is used a lot, and it usually/almost always works, I use it as well sometimes (at my own risk). But since it's not documented, you can't rely on this behaviour.

This link (thanks ypercube!) GROUP BY trick has been optimized away shows a situation in which the same query returns different results between MySql and MariaDB, probably because of a different optimization engine.

So, if this trick works, it's just a matter of luck.

The accepted answer on the other question looks wrong to me:

HAVING wp_posts.post_date = MAX(wp_posts.post_date)

wp_posts.post_date is a non-aggregated column, and its value will be officially undetermined, but it will likely be the first post_date encountered. But since the GROUP BY trick is applied to an unordered table, it is not sure which is the first post_date encountered.

It will probably returns posts that are the only posts of a single author, but even this is not always certain.

A possible solution

I think that this could be a possible solution:

SELECT wp_posts.*
FROM   wp_posts
WHERE  id IN (
  SELECT max(id)
  FROM wp_posts
  WHERE (post_author, post_date) = (
    SELECT   post_author, max(post_date)
    FROM     wp_posts
    WHERE    wp_posts.post_status='publish'
             AND wp_posts.post_type='post'
    GROUP BY post_author
  ) AND wp_posts.post_status='publish'
    AND wp_posts.post_type='post'
  GROUP BY post_author
)

On the inner query I'm returning the maximum post date for every author. I'm then taking into consideration the fact that the same author could theorically have two posts at the same time, so I'm getting only the maximum ID. And then I'm returning all rows that have those maximum IDs. It could be made faster using joins instead of IN clause.

(If you're sure that ID is only increasing, and if ID1 > ID2 also means that post_date1 > post_date2, then the query could be made much more simple, but I'm not sure if this is the case).

Say util.R produces a function foo(). You can check if this function is available in the global environment and source the script if it isn't:

if(identical(length(ls(pattern = "^foo$")), 0))
    source("util.R")

That will find anything with the name foo. If you want to find a function, then (as mentioned by @Andrie) exists() is helpful but needs to be told exactly what type of object to look for, e.g.

if(exists("foo", mode = "function"))
    source("util.R")

Here is exists() in action:

> exists("foo", mode = "function")
[1] FALSE
> foo <- function(x) x
> exists("foo", mode = "function")
[1] TRUE
> rm(foo)
> foo <- 1:10
> exists("foo", mode = "function")
[1] FALSE

As an alternative way you can use DriverManagerDataSource such as:

public DataSource getDataSource(DBInfo db) {

    DriverManagerDataSource dataSource = new DriverManagerDataSource();

    dataSource.setUsername(db.getUsername());
    dataSource.setPassword(db.getPassword());
    dataSource.setUrl(db.getUrl());
    dataSource.setDriverClassName(db.getDriverClassName());

    return dataSource;
}

However be careful about using it, because:

NOTE: This class is not an actual connection pool; it does not actually pool Connections. It just serves as simple replacement for a full-blown connection pool, implementing the same standard interface, but creating new Connections on every call. reference

The attribute selectors are often used for inputs. This is the list of attribute selectors:

[title] All elements with the title attribute are selected.

[title=banana] All elements which have the 'banana' value of the title attribute.

[title~=banana] All elements which contain 'banana' in the value of the title attribute.

[title|=banana] All elements which value of the title attribute starts with 'banana'.

[title^=banana] All elements which value of the title attribute begins with 'banana'.

[title$=banana] All elements which value of the title attribute ends with 'banana'.

[title*=banana] All elements which value of the title attribute contains the substring 'banana'.

Reference: https://kolosek.com/css-selectors/

Yes. But as the variable is concerned it is overwrite (Giving new value to variable. Giving new definition to the function is Override). Just don't declare the variable but initialize (change) in the constructor or static block.

The value will get reflected when using in the blocks of parent class

if the variable is static then change the value during initialization itself with static block,

class Son extends Dad {
    static { 
       me = "son"; 
    }
}

or else change in constructor.

You can also change the value later in any blocks. It will get reflected in super class

Just a simple line of code in the head section can refresh the page

<meta http-equiv="refresh" content="30">

although its not a javascript function, its the simplest way to accomplish the above task hopefully.

As mentioned above:

The difference is scoping. var is scoped to the nearest function block and let is scoped to the nearest enclosing block, which can be smaller than a function block. Both are global if outside any block.Lets see an example:

Example1:

In my both examples I have a function myfunc. myfunc contains a variable myvar equals to 10. In my first example I check if myvar equals to 10 (myvar==10) . If yes, I agian declare a variable myvar (now I have two myvar variables)using var keyword and assign it a new value (20). In next line I print its value on my console. After the conditional block I again print the value of myvar on my console. If you look at the output of myfunc, myvar has value equals to 20.

Example2: In my second example instead of using var keyword in my conditional block I declare myvar using let keyword . Now when I call myfunc I get two different outputs: myvar=20 and myvar=10.

So the difference is very simple i.e its scope.

I have found better option,

<style type="text/css">
    .form {
        margin: 0 auto;
        width: 210px;
    }
    .form label{
        display: inline-block;
        text-align: right;
        float: left;
    }
    .form input{
        display: inline-block;
        text-align: left;
        float: right;
    }
</style>

Demo here: https://jsfiddle.net/durtpwvx/

You can use a function which I have created.

def method_finder(classname):

    non_magic_class = []

    class_methods = dir(classname)

    for m in class_methods:

        if m.startswith('__'):

            continue

        else:

            non_magic_class.append(m)

    return non_magic_class

Output:

 'count',
 'extend',
 'index',

Expanding on the accepted answer, if the input is:

you will still be able to apply the same logic, like this:

#include <fstream>

std::ifstream infile("thefile.txt");
if (infile.is_open()) {
    int number;
    std::string str;
    char c;
    while (infile >> number >> c >> str && c == ',')
        std::cout << number << " " << str << "\n";
}
infile.close();

            return console.error(err)
        data = data.toString()

All the other answers have described how to explicitly specify the location of the java platform, which is fine if you really want to use a specific version of java. However, if you just want to use the most up-to-date version of jdk, and you have that installed in a "normal" place for your operating system, then the best solution is to NOT specify a jdk location. Instead, let the Netbeans launcher search for jdk every time you start it up.

To do this, do not specify jdkhome on the command line, and comment out the line setting netbeans_jdkhome variable in any netbeans.conf files. (See other answers for where to look for these files.)

If you do this, when you install a new version of java, your netbeans will automagically use it. In most cases, that's probably exactly what you want.

To supplement the two-list solutions, here is a solution for processing a single list.

A sample list (NetworkX-related; manually formatted here for readability):

ec_num_list = [((src, tgt), ec_num['ec_num']) for src, tgt, ec_num in G.edges(data=True)]

print('\nec_num_list:\n{}'.format(ec_num_list))
ec_num_list:
[((82, 433), '1.1.1.1'),
  ((82, 433), '1.1.1.2'),
  ((22, 182), '1.1.1.27'),
  ((22, 3785), '1.2.4.1'),
  ((22, 36), '6.4.1.1'),
  ((145, 36), '1.1.1.37'),
  ((36, 154), '2.3.3.1'),
  ((36, 154), '2.3.3.8'),
  ((36, 72), '4.1.1.32'),
  ...] 

Note the duplicate values for the same edges (defined by the tuples). To collate those "values" to their corresponding "keys":

from collections import defaultdict
ec_num_collection = defaultdict(list)
for k, v in ec_num_list:
    ec_num_collection[k].append(v)

print('\nec_num_collection:\n{}'.format(ec_num_collection.items()))
ec_num_collection:
[((82, 433), ['1.1.1.1', '1.1.1.2']),   ## << grouped "values"
((22, 182), ['1.1.1.27']),
((22, 3785), ['1.2.4.1']),
((22, 36), ['6.4.1.1']),
((145, 36), ['1.1.1.37']),
((36, 154), ['2.3.3.1', '2.3.3.8']),    ## << grouped "values"
((36, 72), ['4.1.1.32']),
...] 

If needed, convert that list to dict:

ec_num_collection_dict = {k:v for k, v in zip(ec_num_collection, ec_num_collection)}

print('\nec_num_collection_dict:\n{}'.format(dict(ec_num_collection)))
  ec_num_collection_dict:
  {(82, 433): ['1.1.1.1', '1.1.1.2'],
  (22, 182): ['1.1.1.27'],
  (22, 3785): ['1.2.4.1'],
  (22, 36): ['6.4.1.1'],
  (145, 36): ['1.1.1.37'],
  (36, 154): ['2.3.3.1', '2.3.3.8'],
  (36, 72): ['4.1.1.32'],
  ...}

You want the background color of your main view to be semi-transparent? There's nothing behind it... so nothing will really happen however:

If you want to modify the alpha of any view, use the alpha property:

UIView *someView = [[UIView alloc] init];
...
someView.alpha = 0.8f; //Sets the opacity to 80%
...

Views themselves have the alpha transparency, not just UIColor.

But since your problem is that you can't read text on top of the images... either:

1. [DESIGN] Reconsider the design/placement of the images. Are they necessary as background images? What about the placement of the labels?
2. [CODE] It's not exactly the best solution, but what you could do is create a UIView whose frame takes up the entire page and add some alpha transparency to it. This will create an "overlay" of sorts.

UIView *overlay = [[[UIView alloc] init] autorelease];
overlay.frame = self.view.bounds;
overlay.alpha = 0.2f;
[self.view addSubview:overlay];
... Add the rest of the views

You can just use the method uniq. Assuming your array is ary, call:

ary.uniq{|x| x.user_id}

and this will return a set with unique user_ids.

script - config.sh

USERNAME="satish"

calling script -

#!/bin/bash
source config.sh
echo Welcome ${USERNAME}!
echo Your email is ${EMAIL}.

The answer depends on what is in your hash. If you have a simple hash a simple

print map { "$_ $h{$_}\n" } keys %h;

or

print "$_ $h{$_}\n" for keys %h;

will do, but if you have a hash that is populated with references you will something that can walk those references and produce a sensible output. This walking of the references is normally called serialization. There are many modules that implement different styles, some of the more popular ones are:

• Data::Dumper
• Data::Dump::Streamer
• YAML::XS
• JSON::XS
• XML::Dumper

Due to the fact that Data::Dumper is part of the core Perl library, it is probably the most popular; however, some of the other modules have very good things to offer.

What I have done here is that I have returned a promise from the justTesting function. You can then get the result when the function is resolved.

// new answer

function justTesting() {
  return new Promise((resolve, reject) => {
    if (true) {
      return resolve("testing");
    } else {
      return reject("promise failed");
   }
 });
}

justTesting()
  .then(res => {
     let test = res;
     // do something with the output :)
  })
  .catch(err => {
    console.log(err);
  });

Hope this helps!

// old answer

function justTesting() {
  return promise.then(function(output) {
    return output + 1;
  });
}

justTesting().then((res) => {
     var test = res;
    // do something with the output :)
    }

The only thing that can be a null is a non-primivite.

A boolean which can only hold TRUE or FALSE is a primitive. The TRUE/FALSE in memory are actually numbers (0 and 1)

0 = FALSE

1 = TRUE

So when you instantiate an object it will be null String str; // will equal null

On the other hand if you instaniate a primitive it will be assigned to 0 default.

boolean isTrue; // will be 0

int i; // will be 0

Our system admin resolved this issue by unchecking the box globally for our organization. Users did not even need to log off.

After a lot of digging around I finally ended up downloading the source code of the recovery section of Android. Turns out you can actually send commands to the recovery.

 * The arguments which may be supplied in the recovery.command file:
 *   --send_intent=anystring - write the text out to recovery.intent
 *   --update_package=path - verify install an OTA package file
 *   --wipe_data - erase user data (and cache), then reboot
 *   --wipe_cache - wipe cache (but not user data), then reboot
 *   --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

Those are the commands you can use according to the one I found but that might be different for modded files. So using adb you can do this:

adb shell
recovery --wipe_data

Using --wipe_data seemed to do what I was looking for which was handy although I have not fully tested this as of yet.

EDIT:

For anyone still using this topic, these commands may change based on which recovery you are using. If you are using Clockword recovery, these commands should still work. You can find other commands in /cache/recovery/command

For more information please see here: https://github.com/CyanogenMod/android_bootable_recovery/blob/cm-10.2/recovery.c

Visibility is an animatable property according to the spec, but transitions on visibility do not work gradually, as one might expect. Instead transitions on visibility delay hiding an element. On the other hand making an element visible works immediately. This is as it is defined by the spec (in the case of the default timing function) and as it is implemented in the browsers.

This also is a useful behavior, since in fact one can imagine various visual effects to hide an element. Fading out an element is just one kind of visual effect that is specified using opacity. Other visual effects might move away the element using e.g. the transform property, also see http://taccgl.org/blog/css-transition-visibility.html

It is often useful to combine the opacity transition with a visibility transition! Although opacity appears to do the right thing, fully transparent elements (with opacity:0) still receive mouse events. So e.g. links on an element that was faded out with an opacity transition alone, still respond to clicks (although not visible) and links behind the faded element do not work (although being visible through the faded element). See http://taccgl.org/blog/css-transition-opacity-for-fade-effects.html.

This strange behavior can be avoided by just using both transitions, the transition on visibility and the transition on opacity. Thereby the visibility property is used to disable mouse events for the element while opacity is used for the visual effect. However care must be taken not to hide the element while the visual effect is playing, which would otherwise not be visible. Here the special semantics of the visibility transition becomes handy. When hiding an element the element stays visible while playing the visual effect and is hidden afterwards. On the other hand when revealing an element, the visibility transition makes the element visible immediately, i.e. before playing the visual effect.

Based on answers by Marc Gravell, MichaelGG, and Matt Davis, our developers came up with the following:

Example of use:

string result = string.Empty;

UsingServiceClient.Do(
    new MyServiceClient(),
    client =>
    result = client.GetServiceResult(parameters));

It's as close to the "using" syntax as possible, you don't have to return a dummy value when calling a void method, and you can make multiple calls to the service (and return multiple values) without having to use tuples.

Also, you can use this with ClientBase<T> descendants instead of ChannelFactory if desired.

The extension method is exposed if a developer wants to manually dispose of a proxy/channel instead.

use this code ,it will automatically refresh in 5 seconds, you can change time in refresh

<?php $url1=$_SERVER['REQUEST_URI']; header("Refresh: 5; URL=$url1"); ?>

You could try always sending the first 4 bytes of your data as data size and then read complete data in one shot. Use the below functions on both client and server-side to send and receive data.

def send_data(conn, data):
    serialized_data = pickle.dumps(data)
    conn.sendall(struct.pack('>I', len(serialized_data)))
    conn.sendall(serialized_data)


def receive_data(conn):
    data_size = struct.unpack('>I', conn.recv(4))[0]
    received_payload = b""
    reamining_payload_size = data_size
    while reamining_payload_size != 0:
        received_payload += conn.recv(reamining_payload_size)
        reamining_payload_size = data_size - len(received_payload)
    data = pickle.loads(received_payload)

    return data

FIXED SOLUTION

Run below command in terminal, It denotes where is your virtualbox install on MAC/Linux.

    $ which vboxmanage
    /usr/local/bin/VBoxManage

Genymotion search the virtualBox in /usr/bin/VBoxManage while it is located to /usr/local/bin/VBoxManage , you need to create the symlink to that location , Run in terminal to fix it.

    sudo ln -s /usr/local/bin/VBoxManage /usr/bin/VBoxManage

sql = """\
select field1, field2, field3, field4
from table
where condition1=1
and condition2=2
"""

[edit in responese to comment]
Having an SQL string inside a method does NOT mean that you have to "tabulate" it:

>>> class Foo:
...     def fubar(self):
...         sql = """\
... select *
... from frobozz
... where zorkmids > 10
... ;"""
...         print sql
...
>>> Foo().fubar()
select *
from frobozz
where zorkmids > 10
;
>>>

Use controller.controller_name

In the Rails Guides, it says:

The params hash will always contain the :controller and :action keys, but you should use the methods controller_name and action_name instead to access these values

ActionController Parameters

So let's say you have a CSS class active , that should be inserted in any link whose page is currently open (maybe so that you can style differently) . If you have a static_pages controller with an about action, you can then highlight the link like so in your view:

<li>
  <a class='button <% if controller.controller_name == "static_pages" && controller.action_name == "about" %>active<%end%>' href="/about">
      About Us
  </a>
</li>

Filter the data directly from DataTable or Dataset:

"MyTable".DefaultView.RowFilter = "<DataTable Field> LIKE '%" + textBox1.Text + "%'";
   this.dataGridView1.DataSource = "MyTable".DefaultView;

Use this code on event KeyUp of Textbox, replace "MyTable" for you table name or dataset, replace for the field where you want make the search.

That very well may be a false positive. Like the warning message says, it is common for a capture to start in the middle of a tcp session. In those cases it does not have that information. If you are really missing acks then it is time to start looking upstream from your host for where they are disappearing. It is possible that tshark can not keep up with the data and so it is dropping some metrics. At the end of your capture it will tell you if the "kernel dropped packet" and how many. By default tshark disables dns lookup, tcpdump does not. If you use tcpdump you need to pass in the "-n" switch. If you are having a disk IO issue then you can do something like write to memory /dev/shm. BUT be careful because if your captures get very large then you can cause your machine to start swapping.

My bet is that you have some very long running tcp sessions and when you start your capture you are simply missing some parts of the tcp session due to that. Having said that, here are some of the things that I have seen cause duplicate/missing acks.

1. Switches - (very unlikely but sometimes they get in a sick state)
2. Routers - more likely than switches, but not much
3. Firewall - More likely than routers. Things to look for here are resource exhaustion (license, cpu, etc)
4. Client side filtering software - antivirus, malware detection etc.

Swift 3.0

var attrStr = try! NSAttributedString(
        data: "<b><i>text</i></b>".data(using: String.Encoding.unicode, allowLossyConversion: true)!,
        options: [ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType],
        documentAttributes: nil)
label.attributedText = attrStr

You could also try exectimer. It gives you feedback like:

var t = require("exectimer");

var myFunction() {
   var tick = new t.tick("myFunction");
   tick.start();
   // do some processing and end this tick
   tick.stop();
}

// Display the results
console.log(t.timers.myFunction.duration()); // total duration of all ticks
console.log(t.timers.myFunction.min()); // minimal tick duration
console.log(t.timers.myFunction.max()); // maximal tick duration
console.log(t.timers.myFunction.mean()); // mean tick duration
console.log(t.timers.myFunction.median()); // median tick duration

[edit] There is an even simpler way now to use exectime. Your code could be wrapped like this:

var t = require('exectimer'),
Tick = t.Tick;

for(var i = 1; i < LIMIT; i++){
    Tick.wrap(function saveUsers(done) {
        db.users.save({id : i, name : "MongoUser [" + i + "]"}, function(err, saved) {
            if( err || !saved ) console.log("Error");
            else console.log("Saved");
            done();
        });
    });
}

// Display the results
console.log(t.timers.myFunction.duration()); // total duration of all ticks
console.log(t.timers.saveUsers.min()); // minimal tick duration
console.log(t.timers.saveUsers.max()); // maximal tick duration
console.log(t.timers.saveUsers.mean()); // mean tick duration
console.log(t.timers.saveUsers.median()); // median tick duration

If you are looking to execute a background process via PHP, pipe the command's output to /dev/null and add & to the end of the command.

exec("bg_process > /dev/null &");

Note that you can not utilize the $output parameter of exec() or else PHP will hang (probably until the process completes).

Don't forget to use apply plugin: 'com.android.library' in your build.gradle instead of apply plugin: 'com.android.application'

math.fabs() converts its argument to float if it can (if it can't, it throws an exception). It then takes the absolute value, and returns the result as a float.

In addition to floats, abs() also works with integers and complex numbers. Its return type depends on the type of its argument.

In [7]: type(abs(-2))
Out[7]: int

In [8]: type(abs(-2.0))
Out[8]: float

In [9]: type(abs(3+4j))
Out[9]: float

In [10]: type(math.fabs(-2))
Out[10]: float

In [11]: type(math.fabs(-2.0))
Out[11]: float

In [12]: type(math.fabs(3+4j))

In bootstrap 4

to center the children horizontally, use bootstrap-4 class

justify-content-center

to center the children vertically, use bootstrap-4 class

 align-items-center

but remember don't forget to use d-flex class with these it's a bootstrap-4 utility class, like so

<div class="d-flex justify-content-center align-items-center" style="height:100px;">
    <div class="bg-primary">MIDDLE</div>    
</div>

Note: make sure to add bootstrap-4 utilities if this code does not work

you can also use

Dim intValue as integer = 65  ' letter A for instance
Dim strValue As String = Char.ConvertFromUtf32(intValue)

this doesn't requirement Microsoft.VisualBasic reference

How about:

    For Each oSheet In ActiveWorkbook.Sheets
        If oSheet.ListObjects.Count > 0 Then
          oCmbBox.AddItem oSheet.Name
        End If
    Next oSheet

I used Custom Action separately coded in C++ DLL and used the DLL to call appropriate function on Uninstalling using this syntax :

<CustomAction Id="Uninstall" BinaryKey="Dll_Name" 
              DllEntry="Function_Name" Execute="deferred" />

Using the above code block, I was able to run any function defined in C++ DLL on uninstall. FYI, my uninstall function had code regarding Clearing current user data and registry entries.

Maybe something changed since 2011 but this worked for me:

$ date +"%Y%m%d"
20150330

No need for the -d to get the same appearing result.

You want the path.join() function from os.path.

>>> from os import path
>>> path.join('foo', 'bar')
'foo/bar'

This builds your path with os.sep (instead of the less portable '/') and does it more efficiently (in general) than using +.

However, this won't actually create the path. For that, you have to do something like what you do in your question. You could write something like:

start_path = '/my/root/directory'
final_path = os.join(start_path, *list_of_vars)
if not os.path.isdir(final_path):
    os.makedirs (final_path)

do this in global.asax.cs:

protected void Application_Start()
{
  //string ServerSoftware = Context.Request.ServerVariables["SERVER_SOFTWARE"];
  string server = Context.Request.ServerVariables["SERVER_NAME"];
  string port = Context.Request.ServerVariables["SERVER_PORT"];
  HttpRuntime.Cache.Insert("basePath", "http://" + server + ":" + port + "/");
  // ...
}

works like a charm. this.Context.Request is there...

this.Request throws exception intentionally based on a flag

Since Java 7 there is an easy way to handle character encoding of BufferedWriter and BufferedReaders. You can create a BufferedWriter directly by using the Files class instead of creating various instances of Writer. You can simply create a BufferedWriter, which considers character encoding, by calling:

Files.newBufferedWriter(file.toPath(), StandardCharsets.UTF_8);

You can find more about it in JavaDoc:

• Files class
• Files#newBufferedWriter

set the height to 200

Set the Font to a large variant (150+ px). As already mentioned, control the width using columns, and use a layout manager (or constraint) that will respect the preferred width & height.

Requests doesn't have an equivalent to Urlib2's read().

>>> import requests
>>> response = requests.get("http://www.google.com")
>>> print response.content
'<!doctype html><html itemscope="" itemtype="http://schema.org/WebPage"><head>....'
>>> print response.content == response.text
True

It looks like the POST request you are making is returning no content. Which is often the case with a POST request. Perhaps it set a cookie? The status code is telling you that the POST succeeded after all.

Edit for Python 3:

Python now handles data types differently. response.content returns a sequence of bytes (integers that represent ASCII) while response.text is a string (sequence of chars).

Thus,

>>> print response.content == response.text
False

>>> print str(response.content) == response.text
True
