For Juno: (With Source in E:\workspace and destination in C:\workspace)

1. Copy project directory in its entirety to the workspace directory. (e.g. Copy E:\workspace\HelloWorld C:\workspace\helloWorld)

2. Start Eclipse.

3. Perform: File --> Import

4. Select: General -- > "Existing Project into Workspace"

5. "Next >"

6. Check "Select root Directory"

7. Select with "Browse Button"

8. Select "C:\workspace"

9. A list of existing projects will appear. Just check the ones that are in Bold (To Be Imported) then press the "Finish" button.

Review the Package Explorer and your copied projects should now be there.

In the project file is folder "bin/debug/your_appliacion_name.exe". This is final executable program file.

Running an intent service will be easier. Service in creating a thread in the application but it's still in the application.

My privilege prevents me making my comment on the first post so it will have to go here.

Consideration should be taken into account of 2038 unix bug when setting 20 years in advance from the current date which is suggest as the correct answer above.

Your cookie on January 19, 2018 + (20 years) could well hit 2038 problem depending on the browser and or versions you end up running on.

To compare with an int do this:

<?php
$date = date("m");
$dateToCompareTo = 05;
if (strval($date) == strval($dateToCompareTo)) {
    echo "They are the same";
}
?>

EDIT: 2Toad's answer below is what you're looking for! Upvote that thing

If you're using Angular <= 1.1.4 then this answer will do:

One more answer for this. I'm posting a separate answer, because it's more of an "exact" attempt at a solution than a list of possible solutions:

Here's a filter that will do an "immediate if" (aka iif):

app.filter('iif', function () {
   return function(input, trueValue, falseValue) {
        return input ? trueValue : falseValue;
   };
});

and can be used like this:

{{foo == "bar" | iif : "it's true" : "no, it's not"}}

wrap your entire code block in this:

//<![CDATA[

//code here

//]]>

also make sure to specify the type of script to be text/javascript

try that and let me know how it goes

You can generate NPM dependency trees without the need of installing a dependency by using the command

npm list

This will generate a dependency tree for the project at the current directory and print it to the console.

You can get the dependency tree of a specific dependency like so:

npm list [dependency]

You can also set the maximum depth level by doing

npm list --depth=[depth]

Note that you can only view the dependency tree of a dependency that you have installed either globally, or locally to the NPM project.

If you want to remove the zero digits just before to display on the page or template.

You can use the sprintf() function

sprintf('%g','125.00');
//125

??sprintf('%g','966.70');
//966.7

????sprintf('%g',844.011);
//844.011

This code works for me: I set values whit an INSERT and get the LAST_INSERT_ID() of this value whit a SELECT; I use java NetBeans 8.1, MySql and java.JDBC.driver

                try {

        String Query = "INSERT INTO `stock`(`stock`, `min_stock`,   
                `id_stock`) VALUES ("

                + "\"" + p.get_Stock().getStock() + "\", "
                + "\"" + p.get_Stock().getStockMinimo() + "\","
                + "" + "null" + ")";

        Statement st = miConexion.createStatement();
        st.executeUpdate(Query);

        java.sql.ResultSet rs;
        rs = st.executeQuery("Select LAST_INSERT_ID() from stock limit 1");                
        rs.next(); //para posicionar el puntero en la primer fila
        ultimo_id = rs.getInt("LAST_INSERT_ID()");
        } catch (SqlException ex) { ex.printTrace;}

Replace

  <div style="display:table;">
    <div style="display:table-cell;"></div>
    <div style="display:table-cell;"></div>
  </div>

with

  <table>
    <tr><td>content cell1</td></tr>
    <tr><td>content cell1</td></tr>
  </table>

Look at all the issues surrounding trying to make divs perform like tables. They had to add table-xxx to mimic table layouts

Tables are supported and work very well in all browsers. Why ditch them? the fact that they had to mimic them is proof they did their job and well.

In my opinion use the best tool for the job and if you want tabulated data or something that resembles tabulated data tables just work.

Very Late reply I know but worth voicing.

Instead of using input type button you can use button and insert the image inside the button content.

<button class="btn btn-default">
     <img src="http://i.stack.imgur.com/e2S63.png" width="20" /> Sign In with Facebook
</button>

The problem with doing this only with CSS is that you cannot set linear-gradient to the background you must use solid color.

.sign-in-facebook {

    background-size: 39px 43px;
    padding-left: 41px;

Hope this helps:

function array_keys_exist($searchForKeys = array(), $inArray = array()) {
    $inArrayKeys = array_keys($inArray);
    return count(array_intersect($searchForKeys, $inArrayKeys)) == count($searchForKeys); 
}

function checkLectureStatus($lectureName) {
  global $con;
  $lectureName = mysql_real_escape_string($lectureName);
  $sql = "SELECT 1 FROM preditors_assigned WHERE lecture_name='$lectureName'";
  $result = mysql_query($sql) or trigger_error(mysql_error()." ".$sql);
  if (mysql_fetch_row($result)) {
    return 'Assigned';
  }
  return 'Available';
}

however you have to use some abstraction library for the database access.
the code would become

function checkLectureStatus($lectureName) {
  $res = db::getOne("SELECT 1 FROM preditors_assigned WHERE lecture_name=?",$lectureName);
  if($res) {
    return 'Assigned';
  }
  return 'Available';
}

You can use a UITextView and select Detection for Links, Phone Numbers and other things in the inspector.

you can use

JsonObject.getString("msg"); 

To select the sibling, you'd need something like:

$(this).next();

So, Shog9's comment is not correct. First of all, you'd need to name the variable "clicked" outside of the div click function, otherwise, it is lost after the click occurs.

var clicked;

$("div a").click(function(){
   clicked = $(this).next();
   // Do what you need to do to the newly defined click here
});

// But you can also access the "clicked" element here

A roll your own function.

Supports recursion or not with the 2nd switch.

Also, allow names of files with ; which the accepted answer fails to address although a great answer, this will get over that issue.

Few hints to handle such error/exception for Android Apps:

1. Activities & Application have methods like:

   • onLowMemory
   • onTrimMemory Handle these methods to watch on memory usage.

2. tag in Manifest can have attribute 'largeHeap' set to TRUE, which requests more heap for App sandbox.

3. Managing in-memory caching & disk caching:

   • Images and other data could have been cached in-memory while app running, (locally in activities/fragment and globally); should be managed or removed.

4. Use of WeakReference, SoftReference of Java instance creation , specifically to files.

5. If so many images, use proper library/data structure which can manage memory, use samling of images loaded, handle disk-caching.

6. Handle OutOfMemory exception

7. Follow best practices for coding

   • Leaking of memory (Don't hold everything with strong reference)

8. Minimize activity stack e.g. number of activities in stack (Don't hold everything on context/activty)

   • Context makes sense, those data/instances not required out of scope (activity and fragments), hold them into appropriate context instead global reference-holding.

9. Minimize the use of statics, many more singletons.

10. Take care of OS basic memory fundametals

    • Memory fragmentation issues

11. Involk GC.Collect() manually sometimes when you are sure that in-memory caching no more needed.

FragmentPagerAdapter: the fragment of each page the user visits will be stored in memory, although the view will be destroyed. So when the page is visible again, the view will be recreated but the fragment instance is not recreated. This can result in a significant amount of memory being used. FragmentPagerAdapter should be used when we need to store the whole fragment in memory. FragmentPagerAdapter calls detach(Fragment) on the transaction instead of remove(Fragment).

FragmentStatePagerAdapter: the fragment instance is destroyed when it is not visible to the User, except the saved state of the fragment. This results in using only a small amount of Memory and can be useful for handling larger data sets. Should be used when we have to use dynamic fragments, like fragments with widgets, as their data could be stored in the savedInstanceState.Also it won’t affect the performance even if there are large number of fragments.

Determine if any string is a date

function checkIsAValidDate($myDateString){
    return (bool)strtotime($myDateString);
}

Give the parent a style of overflow: hidden. If it is overlapping sibling elements, you will have to put it inside of a container with a fixed height/width and give that a style of overflow: hidden.

In my case, I already pushed to the repo. Ouch!

You can revert a specific commit while keeping the changes in your local files by doing:

git revert -n <sha>

This way I was able to keep the changes which I needed and undid a commit which had already been pushed.

I'm going to assume that you do not have your secrets.yml checked into source control (ie. it's in the .gitignore file). Even if this isn't your situation, it's what many other people viewing this question have done because they have their code exposed on Github and don't want their secret key floating around.

If it's not in source control, Heroku doesn't know about it. So Rails is looking for Rails.application.secrets.secret_key_base and it hasn't been set because Rails sets it by checking the secrets.yml file which doesn't exist. The simple workaround is to go into your config/environments/production.rb file and add the following line:

Rails.application.configure do
    ...
    config.secret_key_base = ENV["SECRET_KEY_BASE"]
    ...
end

This tells your application to set the secret key using the environment variable instead of looking for it in secrets.yml. It would have saved me a lot of time to know this up front.

No, not in general. Firefox implements const but I know IE doesn't.

@John points to a common naming practice for consts that has been used for years in other languages, I see no reason why you couldn't use that. Of course that doesn't mean someone will not write over the variable's value anyway. :)

Here is a solution for Docker in a script /bin/sh :

docker exec [MYSQL_CONTAINER_NAME] sh -c 'exec echo "[client]" > /root/mysql-credentials.cnf'

docker exec [MYSQL_CONTAINER_NAME] sh -c 'exec echo "user=root" >> /root/mysql-credentials.cnf'

docker exec [MYSQL_CONTAINER_NAME] sh -c 'exec echo "password=$MYSQL_ROOT_PASSWORD" >> /root/mysql-credentials.cnf'

docker exec [MYSQL_CONTAINER_NAME] sh -c 'exec mysqldump --defaults-extra-file=/root/mysql-credentials.cnf --all-databases'

Replace [MYSQL_CONTAINER_NAME] and be sure that the environment variable MYSQL_ROOT_PASSWORD is set in your container.

Hope it will help you like it could help me !

its work for me SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); sdf.format(new Date));

In a rails4 app it is possible to use the change method also for removing columns. The third param is the data_type and in the optional forth you can give options. It is a bit hidden in the section 'Available transformations' on the documentation .

class RemoveFieldFromTableName < ActiveRecord::Migration
  def change
    remove_column :table_name, :field_name, :data_type, {}
  end
end

Every SQL reference I can find says the "any single character" wildcard is the underscore (_), not the question mark (?). That simplifies things a bit, since the underscore is not a regex metacharacter. However, you still can't use Pattern.quote() for the reason given by mmyers. I've got another method here for escaping regexes when I might want to edit them afterward. With that out of the way, the like() method becomes pretty simple:

public static boolean like(final String str, final String expr)
{
  String regex = quotemeta(expr);
  regex = regex.replace("_", ".").replace("%", ".*?");
  Pattern p = Pattern.compile(regex,
      Pattern.CASE_INSENSITIVE | Pattern.DOTALL);
  return p.matcher(str).matches();
}

public static String quotemeta(String s)
{
  if (s == null)
  {
    throw new IllegalArgumentException("String cannot be null");
  }

  int len = s.length();
  if (len == 0)
  {
    return "";
  }

  StringBuilder sb = new StringBuilder(len * 2);
  for (int i = 0; i < len; i++)
  {
    char c = s.charAt(i);
    if ("[](){}.*+?$^|#\\".indexOf(c) != -1)
    {
      sb.append("\\");
    }
    sb.append(c);
  }
  return sb.toString();
}

If you really want to use ? for the wildcard, your best bet would be to remove it from the list of metacharacters in the quotemeta() method. Replacing its escaped form -- replace("\\?", ".") -- wouldn't be safe because there might be backslashes in the original expression.

And that brings us to the real problems: most SQL flavors seem to support character classes in the forms [a-z] and [^j-m] or [!j-m], and they all provide a way to escape wildcard characters. The latter is usually done by means of an ESCAPE keyword, which lets you define a different escape character every time. As you can imagine, this complicates things quite a bit. Converting to a regex is probably still the best option, but parsing the original expression will be much harder--in fact, the first thing you would have to do is formalize the syntax of the LIKE-like expressions themselves.

As @Wilson Vallecilla already mentioned. Please do the below steps to delete the cache:

Please follow below path to discover the files:

C:\Users\your.name.here\AppData\Local\Microsoft\VisualStudio\14.0\ComponentModelCache

Delete all four files:

• Microsoft.VisualStudio.Default.cache
• Microsoft.VisualStudio.Default.catalogs
• Microsoft.VisualStudio.Default.err
• Microsoft.VisualStudio.Default.external

I closed my project, deleted the files on that path and reopened my project, cleaned the solution and built it again and the problem was solved

Deleting your Temporary ASP.NET Files also helps. C:\Users\your.name.here\AppData\Local\Temp\Temporary ASP.NET Files.

This works for me.

Thanks!

Solution in Swift 3:

button.setTitleColor(UIColor.red, for: .normal)

This will set the title color of button.

Let's say the list is:

<ul>
 <li>item1</li>
 <li>item2</li>
 <li>item3</li>
</ul>

For this example. If I understand correctly, you want the list items to be in the middle of the screen, but you want the text IN those list items to be centered to the left of the list item itself. Doing that is actually pretty easy. You just need some CSS:

ul {
    display: table; 
    margin: 0 auto;
    text-align: left;
}

And it works! Here is what is happening. First, we say we want to affect only unordered lists. Then, we do Rafael Herscovici's trick for centering the list items. Finally, we say to align the text to the left of the list items.

ConfigObj is a good alternative to ConfigParser which offers a lot more flexibility:

• Nested sections (subsections), to any level
• List values
• Multiple line values
• String interpolation (substitution)
• Integrated with a powerful validation system including automatic type checking/conversion repeated sections and allowing default values
• When writing out config files, ConfigObj preserves all comments and the order of members and sections
• Many useful methods and options for working with configuration files (like the 'reload' method)
• Full Unicode support

It has some draw backs:

• You cannot set the delimiter, it has to be =… (pull request)
• You cannot have empty values, well you can but they look liked: fuabr = instead of just fubar which looks weird and wrong.

It will work as expected.

No it is not possible in java (Maybe in java 8 it will be avilable). Except the case when you extend in a tree. For example:

class A
class B extends A
class C extends B

Like this... I used it to read Chinese characters...

Dim reader as StreamReader = My.Computer.FileSystem.OpenTextFileReader(filetoimport.Text)
Dim a as String

Do
   a = reader.ReadLine
   '
   ' Code here
   '
Loop Until a Is Nothing

reader.Close()

RedirectToAction("actionName", "controllerName");

It has other overloads as well, please check up!

Also, If you are new and you are not using T4MVC, then I would recommend you to use it!

It gives you intellisence for actions,Controllers,views etc (no more magic strings)

Here is what worked for me. First, let us understand the problem. You cannot use a variable as argument to require. Webpack needs to know what files to bundle at compile time.

When I got the error, I thought it may be related to path issue as in absolute vs relative. So I passed a hard-coded value to require like below: <img src={require("../assets/images/photosnap.svg")} alt="" />. It was working fine. But in my case the value is a variable coming from props. I tried to pass a string literal variable as some suggested. It did not work. Also I tried to define a local method using switch case for all 10 values (I knew it was not best solution, but I just wanted it to work somehow). That too did not work. Then I came to know that we can NOT pass variable to the require.

As a workaround I have modified the data in the data.json file to confine it to just the name of my image. This image name which is coming from the props as a String literal. I concatenated it to the hard coded value, like so:

import React from "react";

function JobCard(props) {  

  const { logo } = props;
  
  return (
      <div className="jobCards">
          <img src={require(`../assets/images/${logo}`)} alt="" /> 
      </div>
    )
} 
  

The actual value contained in the logo would be coming from data.json file and would refer to some image name like photosnap.svg.

JSON in Java has some great resources.

Maven dependency:

<dependency>
  <groupId>org.json</groupId>
  <artifactId>json</artifactId>
  <version>20180813</version>
</dependency>

XML.java is the class you're looking for:

import org.json.JSONObject;
import org.json.XML;
import org.json.JSONException;

public class Main {

    public static int PRETTY_PRINT_INDENT_FACTOR = 4;
    public static String TEST_XML_STRING =
        "<?xml version=\"1.0\" ?><test attrib=\"moretest\">Turn this to JSON</test>";

    public static void main(String[] args) {
        try {
            JSONObject xmlJSONObj = XML.toJSONObject(TEST_XML_STRING);
            String jsonPrettyPrintString = xmlJSONObj.toString(PRETTY_PRINT_INDENT_FACTOR);
            System.out.println(jsonPrettyPrintString);
        } catch (JSONException je) {
            System.out.println(je.toString());
        }
    }
}

Output is:

{"test": {
    "attrib": "moretest",

Here, the paragraph is printed only 'isValid' is true / it contains any value

<p *ngIf="isValid ? true : false">Paragraph</p>

Just for reference, here is a benchmark of different technique rendering performances,

m,

You can do also this way:

  $("#startDateText").datepicker({
                toValue: function (date, format, language) {
                    var d = new Date(date);
                    d.setDate(d.getDate());
                    return new Date(d);
                },
                autoclose: true
            });

Here are the outputs of isset() and empty() for the 4 possibilities: undeclared, null, false and true.

$a=null;
$b=false;
$c=true;

var_dump(array(isset($z1),isset($a),isset($b),isset($c)),true); //$z1 previously undeclared
var_dump(array(empty($z2),empty($a),empty($b),empty($c)),true); //$z2 previously undeclared

//array(4) { [0]=> bool(false) [1]=> bool(false) [2]=> bool(true) [3]=> bool(true) } 
//array(4) { [0]=> bool(true) [1]=> bool(true) [2]=> bool(true) [3]=> bool(false) } 

You'll notice that all the 'isset' results are opposite of the 'empty' results except for case $b=false. All the values (except null which isn't a value but a non-value) that evaluate to false will return true when tested for by isset and false when tested by 'empty'.

So use isset() when you're concerned about the existence of a variable. And use empty when you're testing for true or false. If the actual type of emptiness matters, use is_null and ===0, ===false, ===''.

You can either use regex, or keep on using str_replace.

Eg.

$url = parse_url($_SERVER['REQUEST_URI']);

if ($url != '/') {
    parse_str($url['query']);
    echo $id;
    echo $othervar;
}

Output will be: http://www.testing.com/123/123

Once changes has been committed it will not be able to delete. because commit's basic nature is not to delete.

Thing you can do (easy and safe method),

Interactive Rebase:

1) git rebase -i HEAD~2 #will show your recent 2 commits

2) Your commit will list like , Recent will appear at the bottom of the page LILO(last in Last Out)

Delete the last commit row entirely

3) save it by ctrl+X or ESC:wq

now your branch will updated without your last commit..

You may be able to do this by modifying the request options as below. If you are using a self-signed certificate or a missing intermediary, setting strictSSL to false will not force request package to validate the certificate.

var options = {
   host: 'jira.example.com',
   path: '/secure/attachment/206906/update.xlsx',
   strictSSL: false
}

Adding to the accepted answer, there is one more reason due to which elevation may not work as expected if the Bluelight filter feature on the phone is ON.

I was facing this issue when the elevation appeared completely distorted and unbearable in my device. But the elevation was fine in the preview. Turning off the Bluelight filter on phone resolved the issue.

So even after setting

android:outlineProvider="bounds"

The elevation is not working properly, then you can try to tinker with phone's color settings.

 X <- data.frame(Variable1=c(11,14,12,15),Variable2=c(2,3,1,4))
> X
  Variable1 Variable2
1        11         2
2        14         3
3        12         1
4        15         4
> X[X$Variable1!=11 & X$Variable1!=12, ]
  Variable1 Variable2
2        14         3
4        15         4
> X[ ! X$Variable1 %in% c(11,12), ]
  Variable1 Variable2
2        14         3
4        15         4

You can functionalize this however you like.

You might be able to mask the jagging using blurred box-shadows. Using -webkit-box-shadow instead of box-shadow will make sure it doesn't affect non-webkit browsers. You might want to check Safari and the mobile webkit browsers though.

The result is somewhat better, but still a lot less good then with the other browsers:

why not simply

public Date(){
    data = new int[]{0,0,0};
}

the reason you got the error is because int[] data = ... declares a new variable and hides the field data

however it should be noted that the contents of the array are already initialized to 0 (the default value of int)

Just like others explained - your problem stemmed from using \, which is escape character in string literal/constant. OTOH, if you had that file path string from another source (read from file, console or returned by os function) - there wouldn't have been problem splitting on '\\' or r'\'.

And just like others suggested, if you want to use \ in program literal, you have to either duplicate it \\ or the whole literal has to be prefixed by r, like so r'lite\ral' or r"lite\ral" to avoid the parser converting that \ and r to CR (carriage return) character.

There is one more way though - just don't use backslash \ pathnames in your code! Since last century Windows recognizes and works fine with pathnames which use forward slash as directory separator /! Somehow not many people know that.. but it works:

>>> var = "d:/stuff/morestuff/furtherdown/THEFILE.txt"
>>> var.split('/')
['d:', 'stuff', 'morestuff', 'furtherdown', 'THEFILE.txt']

This by the way will make your code work on Unix, Windows and Mac... because all of them do use / as directory separator... even if you don't want to use the predefined constants of module os.

You can try removing the width and height attributes on the svg root element, adding preserveAspectRatio="none" viewBox="0 0 1024 800" instead. It makes a difference in Opera at least, assuming you wanted the svg to stretch to fill the entire region defined by the CSS styles.

This is how I do it.

[[[UIApplication sharedApplication] delegate] performSelector:@selector(nameofMethod)];

Dont forget to import.

#import "AppDelegate.h"

I managed to condense it into two lines of code:

string = input("Enter your string\n")
print(len(string) - string.count(" "))

i needed to calculate the content length aswell

const formHeaders = form.getHeaders();
formHeaders["Content-Length"] = form.getLengthSync()

const config = {headers: formHeaders}

return axios.post(url, form, config)
.then(res => {
    console.log(`form uploaded`)
})

If your data is already serialized:

a) send a JSON response

public function someAction()
{
    $response = new Response();
    $response->setContent(file_get_contents('path/to/file'));
    $response->headers->set('Content-Type', 'application/json');
    return $response;
}

b) send a JSONP response (with callback)

public function someAction()
{
    $response = new Response();
    $response->setContent('/**/FUNCTION_CALLBACK_NAME(' . file_get_contents('path/to/file') . ');');
    $response->headers->set('Content-Type', 'text/javascript');
    return $response;
}

If your data needs be serialized:

c) send a JSON response

public function someAction()
{
    $response = new JsonResponse();
    $response->setData([some array]);
    return $response;
}

d) send a JSONP response (with callback)

public function someAction()
{
    $response = new JsonResponse();
    $response->setData([some array]);
    $response->setCallback('FUNCTION_CALLBACK_NAME');
    return $response;
}

e) use groups in Symfony 3.x.x

Create groups inside your Entities

<?php

namespace Mindlahus;

use Symfony\Component\Serializer\Annotation\Groups;

/**
 * Some Super Class Name
 *
 * @ORM    able("table_name")
 * @ORM\Entity(repositoryClass="SomeSuperClassNameRepository")
 * @UniqueEntity(
 *  fields={"foo", "boo"},
 *  ignoreNull=false
 * )
 */
class SomeSuperClassName
{
    /**
     * @Groups({"group1", "group2"})
     */
    public $foo;
    /**
     * @Groups({"group1"})
     */
    public $date;

    /**
     * @Groups({"group3"})
     */
    public function getBar() // is* methods are also supported
    {
        return $this->bar;
    }

    // ...
}

Normalize your Doctrine Object inside the logic of your application

<?php

use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Serializer\Mapping\Factory\ClassMetadataFactory;
// For annotations
use Doctrine\Common\Annotations\AnnotationReader;
use Symfony\Component\Serializer\Mapping\Loader\AnnotationLoader;
use Symfony\Component\Serializer\Serializer;
use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;
use Symfony\Component\Serializer\Encoder\JsonEncoder;

...

$repository = $this->getDoctrine()->getRepository('Mindlahus:SomeSuperClassName');
$SomeSuperObject = $repository->findOneById($id);

$classMetadataFactory = new ClassMetadataFactory(new AnnotationLoader(new AnnotationReader()));
$encoder = new JsonEncoder();
$normalizer = new ObjectNormalizer($classMetadataFactory);
$callback = function ($dateTime) {
    return $dateTime instanceof \DateTime
        ? $dateTime->format('m-d-Y')
        : '';
};
$normalizer->setCallbacks(array('date' => $callback));
$serializer = new Serializer(array($normalizer), array($encoder));
$data = $serializer->normalize($SomeSuperObject, null, array('groups' => array('group1')));

$response = new Response();
$response->setContent($serializer->serialize($data, 'json'));
$response->headers->set('Content-Type', 'application/json');
return $response;

Yes, it means unsigned int. It used to be that if you didn't specify a data type in C there were many places where it just assumed int. This was try, for example, of function return types.

This wart has mostly been eradicated, but you are encountering its last vestiges here. IMHO, the code should be fixed to say unsigned int to avoid just the sort of confusion you are experiencing.

class B
{
public:
    B()
    {
       p = new int[1024];  
    }
    virtual ~B()
    {
        cout<<"B destructor"<<endl;
        //p will not be deleted EVER unless you do it manually.
    }
    int *p;
};


class D : public B
{
public:
    virtual ~D()
    {
        cout<<"D destructor"<<endl;
    }
};

When you do:

B *pD = new D();
delete pD;

The destructor will be called only if your base class has the virtual keyword.

Then if you did not have a virtual destructor only ~B() would be called. But since you have a virtual destructor, first ~D() will be called, then ~B().

No members of B or D allocated on the heap will be deallocated unless you explicitly delete them. And deleting them will call their destructor as well.

One more scenario of this error:

Install typescript locally and run the command without npm run

First, it is important to notice this is a "general" terminal error (Even if you write hello bla.js -or- wowowowow index.js):

"hello world" example of this error:

1. You install typescript locally (without -g) ==> npm install typescript. https://docs.npmjs.com/downloading-and-installing-packages-locally
2. In this case tsc commands available if you run npm run inside your local project. For example: npm run tsc -v:

-or- install typescript globally (Like other answer mention).

function isInteger(n) {
   return ((typeof n==='number')&&(n%1===0));
}

function isFloat(n) {
   return ((typeof n==='number')&&(n%1!==0));
}

   return (typeof n==='number');
}

Looks like moment.js is the most popular and with active development:

moment("2010-01-01T05:06:07", moment.ISO_8601);

You can use the substr function like this:

echo substr($myStr, 0, 5);

The second argument to substr is from what position what you want to start and third arguments is for how many characters you want to return.

A snippet of your original code:

$("#buttons li a").click(function(){
    $("#buttons li a").removeClass('selected');
    $(this).addClass('selected');
    document.location.hash=$(this).attr("id")
});

Change this to:

$("#buttons li a").click(function(e){
    // need to pass in "e", which is the actual click event
    e.preventDefault();
    // the preventDefault() function ... prevents the default action.
    $("#buttons li a").removeClass('selected');
    $(this).addClass('selected');
    document.location.hash=$(this).attr("id")
});

I ran into the same issue, but it was an issue with the actual site settings in IIS.

Select Advanced Settings... for your site/application and then look at the Enabled Protocols value. For whatever reson the value was blank for my site and caused the following error:

HTTP Error 503. The service is unavailable.

The fix was to add in http and select OK. The site was then functional again.

From MySQL 5.7 Reference Manual.

Syntax :

ALTER TABLE t1 CHANGE a b DATATYPE;

e.g. : for Customer TABLE having COLUMN customer_name, customer_street, customercity.

And we want to change customercity TO customer_city :

alter table customer change customercity customer_city VARCHAR(225);

display is not an attribute - it's a CSS property. You need to access the style object for this:

document.getElementById('classRight').style.display = 'none';

I think the Apache Commons Lang library's StringEscapeUtils.unescapeHtml3() and unescapeHtml4() methods are what you are looking for. See https://commons.apache.org/proper/commons-text/javadocs/api-release/org/apache/commons/text/StringEscapeUtils.html.

No.

From the cron man page:

...cron will then examine the modification time on all crontabs and reload those which have changed. Thus cron need not be restarted whenever a crontab file is modified

But if you just want to make sure its done anyway,

sudo service cron reload

or

/etc/init.d/cron reload

Try to run xcrun simctl delete unavailable in your terminal.

Original answer: Xcode - free to clear devices folder?

Try following from Removing duplicates from an Array(simple):

Array.prototype.removeDuplicates = function (){
  var temp=new Array();
  this.sort();
  for(i=0;i<this.length;i++){
    if(this[i]==this[i+1]) {continue}
    temp[temp.length]=this[i];
  }
  return temp;
} 

Edit:

This code doesn't need sort:

Array.prototype.removeDuplicates = function (){
  var temp=new Array();
  label:for(i=0;i<this.length;i++){
        for(var j=0; j<temp.length;j++ ){//check duplicates
            if(temp[j]==this[i])//skip if already present 
               continue label;      
        }
        temp[temp.length] = this[i];
  }
  return temp;
 } 

(But not a tested code!)

I faced something like that in one of the old and legacy projects that i worked in that not contains any interfaces or best practice and also it's too hard to enforce them build things again or refactoring the code due to the maturity of the project business, So in my UnitTest project i used to create a Wrapper over the classes that I want to mock and that wrapper implement interface which contains all my needed methods that I want to setup and work with, Now I can mock the wrapper instead of the real class.

For Example:

Service you want to test which not contains virtual methods or implement interface

public class ServiceA{

public void A(){}

public String B(){}

}

Wrapper to moq

public class ServiceAWrapper : IServiceAWrapper{

public void A(){}

public String B(){}

}

The Wrapper Interface

public interface IServiceAWrapper{

void A();

String B();

}

In the unit test you can now mock the wrapper:

    public void A_Run_ChangeStateOfX()
    {
    var moq = new Mock<IServiceAWrapper>();
    moq.Setup(...);
    }

This might be not the best practice, but if your project rules force you in this way, do it. Also Put all your Wrappers inside your Unit Test project or Helper project specified only for the unit tests in order to not overload the project with unneeded wrappers or adaptors.

Update: This answer from more than a year but in this year i faced a lot of similar scenarios with different solutions. For example it's so easy to use Microsoft Fake Framework to create mocks, fakes and stubs and even test private and protected methods without any interfaces. You can read: https://docs.microsoft.com/en-us/visualstudio/test/isolating-code-under-test-with-microsoft-fakes?view=vs-2017

Please find inner join for more than 2 table here

Here are 4 table name like

1. Orders
2. Customers
3. Student
4. Lecturer

So the SQL code would be:

select o.orderid, c.customername, l.lname, s.studadd, s.studmarks 
from orders o 
    inner join customers c on o.customrid = c.customerid 
    inner join lecturer l  on o.customrid = l.id 
    inner join student s   on o.customrid=s.studmarks;

If you are using cmake, you can use:

Or

SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pthread")

(Following is a late but complete answer)

FileReader methods support

FileReader.readAsBinaryString() is deprecated. Don't use it! It's no longer in the W3C File API working draft:

void abort();
void readAsArrayBuffer(Blob blob);
void readAsText(Blob blob, optional DOMString encoding);
void readAsDataURL(Blob blob);

NB: Note that File is a kind of extended Blob structure.

Mozilla still implements readAsBinaryString() and describes it in MDN FileApi documentation:

void abort();
void readAsArrayBuffer(in Blob blob); Requires Gecko 7.0
void readAsBinaryString(in Blob blob);
void readAsDataURL(in Blob file);
void readAsText(in Blob blob, [optional] in DOMString encoding);

The reason behind readAsBinaryString() deprecation is in my opinion the following: the standard for JavaScript strings are DOMString which only accept UTF-8 characters, NOT random binary data. So don't use readAsBinaryString(), that's not safe and ECMAScript-compliant at all.

We know that JavaScript strings are not supposed to store binary data but Mozilla in some sort can. That's dangerous in my opinion. Blob and typed arrays (ArrayBuffer and the not-yet-implemented but not necessary StringView) were invented for one purpose: allow the use of pure binary data, without UTF-8 strings restrictions.

XMLHttpRequest upload support

XMLHttpRequest.send() has the following invocations options:

void send();
void send(ArrayBuffer data);
void send(Blob data);
void send(Document data);
void send(DOMString? data);
void send(FormData data);

XMLHttpRequest.sendAsBinary() has the following invocations options:

void sendAsBinary(   in DOMString body );

sendAsBinary() is NOT a standard and may not be supported in Chrome.

Solutions

So you have several options:

1. send() the FileReader.result of FileReader.readAsArrayBuffer ( fileObject ). It is more complicated to manipulate (you'll have to make a separate send() for it) but it's the RECOMMENDED APPROACH.
2. send() the FileReader.result of FileReader.readAsDataURL( fileObject ). It generates useless overhead and compression latency, requires a decompression step on the server-side BUT it's easy to manipulate as a string in Javascript.
3. Being non-standard and sendAsBinary() the FileReader.result of FileReader.readAsBinaryString( fileObject )

MDN states that:

The best way to send binary content (like in files upload) is using ArrayBuffers or Blobs in conjuncton with the send() method. However, if you want to send a stringifiable raw data, use the sendAsBinary() method instead, or the StringView (Non native) typed arrays superclass.

Since I had a similar situation, I thought I'd share my situation and how these answers helped me (thanks everyone).

So I decided to work locally by amending my last commit every time I wanted to save my progress on the main branch (I know, I should've branched out, committed on that, kept pushing and later merge back to master).

One late night, in paranoid fear of loosing my progress to hardware failure or something out of the ether, I decided to push master to origin. Later I kept amending my local master branch and when I decided it's time to push again, I was faced with different master branches and found out I can't amend origin/upstream (duh!) like I can local development branches.

So I didn't checkout master locally because I already was after a commit. Master was unchanged. I didn't even need to reset --hard, my current commit was OK.

I just forced push to origin, without even specifying what commit I wanted to force on master since in this case it's whatever HEAD is at. Checked git diff master..origin/master so there weren't any differences and that's it. All fixed. Thanks! (I know, I'm a git newbie, please forgive!).

So if you're already OK with your master branch locally, just:

git push --force origin master
git diff master..origin/master

socket.disconnect() can be used only on the client side, not on the server side.

Client.emit('disconnect') triggers the disconnection event on the server, but does not effectively disconnect the client. The client is not aware of the disconnection.

So the question remain : how to force a client to disconnect from server side ?

Html.Raw() returns IHtmlString, not the ordinary string. So, you cannot write them in opposite sides of : operator. Remove that .ToString() calling

@{int count = 0;}
@foreach (var item in Model.Resources)
{
    @(count <= 3 ? Html.Raw("<div class=\"resource-row\">"): Html.Raw("")) 
    // some code
    @(count <= 3 ? Html.Raw("</div>") : Html.Raw("")) 
    @(count++)

}

By the way, returning IHtmlString is the way MVC recognizes html content and does not encode it. Even if it hasn't caused compiler errors, calling ToString() would destroy meaning of Html.Raw()

In html

$('#raisepay_id').attr("readonly", true) 

$("#raisepay_id").prop("readonly",true);

in bootstrap

$('#raisepay_id').attr("disabled", true) 

$("#raisepay_id").prop("disabled",true);

JQuery is a changing library and sometimes they make regular improvements. .attr() is used to get attributes from the HTML tags, and while it is perfectly functional .prop() was added later to be more semantic and it works better with value-less attributes like 'checked' and 'selected'.

It is advised that if you are using a later version of JQuery you should use .prop() whenever possible.

The code you posted starts three different processes each with it's own command. To open a command prompt and then run a command try the following (never tried it myself):

try {
    // Execute command
    String command = "cmd /c start cmd.exe";
    Process child = Runtime.getRuntime().exec(command);

    // Get output stream to write from it
    OutputStream out = child.getOutputStream();

    out.write("cd C:/ /r/n".getBytes());
    out.flush();
    out.write("dir /r/n".getBytes());
    out.close();
} catch (IOException e) {
}

Filter can be a JavaScript object with fields and you can have expression as:

To only modify the title's font (and not the font of the axis) I used this:

import matplotlib.pyplot as plt
fig = plt.Figure()
ax = fig.add_subplot(111)
ax.set_title('My Title', fontdict={'fontsize': 8, 'fontweight': 'medium'})

The fontdict accepts all kwargs from matplotlib.text.Text.

1. add https://momentjs.com/downloads/moment-with-locales.js to your html page
2. var todayDate = moment().format('DD-MM-YYYY');//to get today date 06/03/2018 if you want to add extra day to your current date then
3. var dueDate = moment().add(15,'days').format('DD-MM-YYYY')// to add 15 days to current date..

point 2 and 3 are using in your jquery code...

if you are using SQL 2012 you should try

        Quantity,

if available, better order by date column.

First find the condition that occurs in all situations, then filter the special conditions:

$('[myc="blue"]')
    .filter('[myid="1"],[myid="3"]');

maybe you can try using

SELECT user_name
FROM user_master
WHERE upper(user_name) LIKE '%ME%'

I have no idea why the other answers didn't work for me (error 500) but this works

@GetMapping("")
public String getAll() {
    List<Entity> entityList = entityManager.findAll();
    List<JSONObject> entities = new ArrayList<JSONObject>();
    for (Entity n : entityList) {
        JSONObject Entity = new JSONObject();
        entity.put("id", n.getId());
        entity.put("address", n.getAddress());
        entities.add(entity);
    }
    return entities.toString();
}

I found this to work very well, but initially I have my textboxes on a panel so none of my textboxes cleared as expected so I added

this.panel1.Controls.....  

Which got me to thinking that is you have lots of textboxes for different functions and only some need to be cleared out, perhaps using the multiple panel hierarchies you can target just a few and not all.

foreach ( TextBox tb in this.Controls.OfType<TextBox>()) {
  ..
}

matcher.find() does what you needed. Example:

Pattern.compile("stores.*store.*product").matcher(someString).find();

There's no difference, == is a synonym for = (for the C/C++ people, I assume). See here, for example.

You could double-check just to be really sure or just for your interest by looking at the bash source code, should be somewhere in the parsing code there, but I couldn't find it straightaway.

The definitions are detailed at the Maven site's page Introduction to the Build Lifecycle, but I have tried to summarize:

Maven defines 4 items of a build process:

1. Lifecycle

   Three built-in lifecycles (aka build lifecycles): default, clean, site. (Lifecycle Reference)

2. Phase

   Each lifecycle is made up of phases, e.g. for the default lifecycle: compile, test, package, install, etc.

3. Plugin

   An artifact that provides one or more goals.

   Based on packaging type (jar, war, etc.) plugins' goals are bound to phases by default. (Built-in Lifecycle Bindings)

4. Goal

   The task (action) that is executed. A plugin can have one or more goals.

   One or more goals need to be specified when configuring a plugin in a POM. Additionally, in case a plugin does not have a default phase defined, the specified goal(s) can be bound to a phase.

Maven can be invoked with:

1. a phase (e.g clean, package)

I found the answer.It was because of the variables. Like int a and string a. there were two variables with the same name.

i faced an issue something like this...

Actually, in two ways you can process find command output in copy command

1. If find command's output doesn't contain any space i.e if file name doesn't contain space in it then you can use below mentioned command:

   Syntax: find <Path> <Conditions> | xargs cp -t <copy file path>

   Example: find -mtime -1 -type f | xargs cp -t inner/

2. But most of the time our production data files might contain space in it. So most of time below mentioned command is safer:

   Syntax: find <path> <condition> -exec cp '{}' <copy path> \;

   Example find -mtime -1 -type f -exec cp '{}' inner/ \;

In the second example, last part i.e semi-colon is also considered as part of find command, that should be escaped before press the enter button. Otherwise you will get an error something like this

find: missing argument to `-exec'

In your case, copy command syntax is wrong in order to copy find file into /home/shantanu/tosend. The following command will work:

find /home/shantanu/processed/ -name '*2011*.xml' -exec cp  {} /home/shantanu/tosend \;

Try to do something like this:

<!--Include jQuery-->
<script type="text/javascript" src="jquery.min.js"></script> 

<script type="text/javascript"> 
function doSomething() { 
    $.get("somepage.php"); 
    return false; 
} 
</script>

<a href="#" onclick="doSomething();">Click Me!</a>

Place your widget.js after core.js, but before any other jquery that calls the widget.js file. (Example: draggable.js) Precedence (order) matters in what javascript/jquery can 'see'. Always position helper code before the code that uses the helper code.

I did not know about DMBS_METADATA, but your answers prompted me to create a utility to script all objects owned by an Oracle user.

I know this is an old post, but there is a FAR simpler answer (though maybe it only works in newer versions of windows). Just use the /t parameter for the DATE and TIME dos commands to only show the date or time and not prompt you to set it, like this:

@echo off
echo Starting test batch file > testlog.txt
date /t >> testlog.txt
time /t >> testlog.txt

CERAS is a class name which cannot be assigned. As the class implements IDisposable a typical usage would be:

using (CERas.CERAS ceras = new CERas.CERAS())
{
    // call some method on ceras
}

If you are doing this for virtualenv, the kernels in inactive environments might not be shown with jupyter kernelspec list, as suggested above. You can delete it from directory:

~/.local/share/jupyter/kernels/

Collection is a high-level interface describing Java objects that can contain collections of other objects. It's not very specific about how they are accessed, whether multiple copies of the same object can exist in the same collection, or whether the order is important. List is specifically an ordered collection of objects. If you put objects into a List in a particular order, they will stay in that order.

And deciding where to use these two interfaces is much less important than deciding what the concrete implementation you use is. This will have implications for the time and space performance of your program. For example, if you want a list, you could use an ArrayList or a LinkedList, each of which is going to have implications for the application. For other collection types (e.g. Sets), similar considerations apply.

OK here are my 2 cents: try passing path with each backslash as double backslash. I have found sometimes calling WIN API requires that.

As of now (studio 0.61) maintaining proper project structure is enough. No need to create separate test project as in eclipse (see below).

To get the current time in the local timezone as a naive datetime object:

from datetime import datetime
naive_dt = datetime.now()

If it doesn't return the expected time then it means that your computer is misconfigured. You should fix it first (it is unrelated to Python).

To get the current time in UTC as a naive datetime object:

naive_utc_dt = datetime.utcnow()

To get the current time as an aware datetime object in Python 3.3+:

from datetime import datetime, timezone

utc_dt = datetime.now(timezone.utc) # UTC time
dt = utc_dt.astimezone() # local time

To get the current time in the given time zone from the tz database:

import pytz

tz = pytz.timezone('Europe/Berlin')
berlin_now = datetime.now(tz)

It works during DST transitions. It works if the timezone had different UTC offset in the past i.e., it works even if the timezone corresponds to multiple tzinfo objects at different times.

If you want an open source version (I think there are some Asterisk integration projects based on this one).

you can just wrap it into another element and call html after that:

$('<div><iframe width="854" height="480" src="http://www.youtube.com/embed/gYKqrjq5IjU?feature=oembed" frameborder="0" allowfullscreen></iframe></div>').html();

note that outerHTML doesn't exist on older browsers but innerHTML still does (it doesn't exist for example in ff < 11 while it's still used on many older computers)

Eric pretty much nailed it. We (Bitnami) are a popular provider of free AMIs for popular applications and development frameworks (PHP, Joomla, Drupal, you get the idea). I can tell you that EBS-backed AMIs are significantly more popular than S3-backed. In general I think s3-backed instances are used for distributed, time-limited jobs (for example, large scale processing of data) where if one machine fails, another one is simply spinned up. EBS-backed AMIS tend to be used for 'traditional' server tasks, such as web or database servers that keep state locally and thus require the data to be available in the case of crashing.

One aspect I did not see mentioned is the fact that you can take snapshots of an EBS-backed instance while running, effectively allowing you to have very cost-effective backups of your infrastructure (the snapshots are block-based and incremental)

This exact question is answered on mySql workbench-faq:

Hover over an acronym to view a description, and see the Section 8.1.11.2, “The Columns Tab” and MySQL CREATE TABLE documentation for additional details.

That means hover over an acronym in the mySql Workbench table editor.

Section 8.1.11.2, “The Columns Tab”

Here's a suggestion: use two indices into the string, say start and end. start points to the first character of the next string to extract, end points to the character after the last one belonging to the next string to extract. start starts at zero, end gets the position of the first char after start. Then you take the string between [start..end) and add that to your array. You keep going until you hit the end of the string.

String filePath = Environment.getExternalStorageDirectory()+"/yourfolderNAme/yopurfile.mp3";
mediaPlayer = new  MediaPlayer();
mediaPlayer.setDataSource(filePath);
mediaPlayer.prepare();   
mediaPlayer.start()

and this play from raw folder.

int resID = myContext.getResources().getIdentifier(playSoundName,"raw",myContext.getPackageName());

            MediaPlayer mediaPlayer = MediaPlayer.create(myContext,resID);
            mediaPlayer.prepare();
            mediaPlayer.start();

mycontext=application.this. use.

Try this:

String hourMinute = DateTime.Now.ToString("HH:mm");

Now you will get the time in hour:minute format.

Use Encoding.Convert to adjust the byte array before attempting to decode it into your destination encoding.

Encoding iso = Encoding.GetEncoding("ISO-8859-1");
Encoding utf8 = Encoding.UTF8;

byte[] isoBytes = Encoding.Convert(utf8, iso, utfBytes);
string msg = iso.GetString(isoBytes);

Note first that your question shows a bit of misunderstanding. origin/HEAD represents the default branch on the remote, i.e. the HEAD that's in that remote repository you're calling origin. When you switch branches in your repo, you're not affecting that. The same is true for remote branches; you might have master and origin/master in your repo, where origin/master represents a local copy of the master branch in the remote repository.

origin's HEAD will only change if you or someone else actually changes it in the remote repository, which should basically never happen - you want the default branch a public repo to stay constant, on the stable branch (probably master). origin/HEAD is a local ref representing a local copy of the HEAD in the remote repository. (Its full name is refs/remotes/origin/HEAD.)

I think the above answers what you actually wanted to know, but to go ahead and answer the question you explicitly asked... origin/HEAD is set automatically when you clone a repository, and that's about it. Bizarrely, that it's not set by commands like git remote update - I believe the only way it will change is if you manually change it. (By change I mean point to a different branch; obviously the commit it points to changes if that branch changes, which might happen on fetch/pull/remote update.)

Edit: The problem discussed below was corrected in Git 1.8.4.3; see this update.

There is a tiny caveat, though. HEAD is a symbolic ref, pointing to a branch instead of directly to a commit, but the git remote transfer protocols only report commits for refs. So Git knows the SHA1 of the commit pointed to by HEAD and all other refs; it then has to deduce the value of HEAD by finding a branch that points to the same commit. This means that if two branches happen to point there, it's ambiguous. (I believe it picks master if possible, then falls back to first alphabetically.) You'll see this reported in the output of git remote show origin:

$ git remote show origin
* remote origin
  Fetch URL: ...
  Push  URL: ...
  HEAD branch (remote HEAD is ambiguous, may be one of the following):
    foo
    master

Oddly, although the notion of HEAD printed this way will change if things change on the remote (e.g. if foo is removed), it doesn't actually update refs/remotes/origin/HEAD. This can lead to really odd situations. Say that in the above example origin/HEAD actually pointed to foo, and origin's foo branch was then removed. We can then do this:

$ git remote show origin
...
HEAD branch: master
$ git symbolic-ref refs/remotes/origin/HEAD
refs/remotes/origin/foo
$ git remote update --prune origin
Fetching origin
 x [deleted]         (none)     -> origin/foo
   (refs/remotes/origin/HEAD has become dangling)

So even though remote show knows HEAD is master, it doesn't update anything. The stale foo branch is correctly pruned, and HEAD becomes dangling (pointing to a nonexistent branch), and it still doesn't update it to point to master. If you want to fix this, use git remote set-head origin -a, which automatically determines origin's HEAD as above, and then actually sets origin/HEAD to point to the appropriate remote branch.

interface were primarily made popular by Java.
Below are the nature of interface and its C++ equivalents:

1. interface can contain only body-less abstract methods; C++ equivalent is pure virtual methods, though they can/cannot have body
2. interface can contain only static final data members; C++ equivalent is static const data members which are compile time constants
3. Multiple interface can be implemented by a Java class, this facility is needed because a Java class can inherit only 1 class; C++ supports multiple inheritance straight away with help of virtual keyword when needed

Because of point 3 interface concept was never formally introduced in C++. Still one can have a flexibility to do that.

Besides this you can refer Bjarne's FAQ on this topic.

Since Python 3.5, things are much easier with os.scandir()

with os.scandir(path) as it:
    for entry in it:
        if entry.name.endswith(".asm") and entry.is_file():
            print(entry.name, entry.path)

Using scandir() instead of listdir() can significantly increase the performance of code that also needs file type or file attribute information, because os.DirEntry objects expose this information if the operating system provides it when scanning a directory. All os.DirEntry methods may perform a system call, but is_dir() and is_file() usually only require a system call for symbolic links; os.DirEntry.stat() always requires a system call on Unix but only requires one for symbolic links on Windows.

AlgorithmIdentifier sha1aid_ = new AlgorithmIdentifier(sha1oid_, null);
DigestInfo di = new DigestInfo(sha1aid_, digest);

byte[] plainSig = di.getDEREncoded();
Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding", BOUNCY_CASTLE_PROVIDER);
cipher.init(Cipher.ENCRYPT_MODE, privateKey);
byte[] signature = cipher.doFinal(plainSig);

It depends on what datatype you set for your db table.

DATETIME (datatype)

INSERT INTO t1 (dateposted) VALUES ( NOW() )
// This will insert date and time into the col. Do not use quote around the val

$dt = date('Y-m-d h:i:s');
INSERT INTO t1 (dateposted) VALUES ( '$dt' )
// This will insert date into the col using php var. Wrap with quote.

DATE (datatype)

INSERT INTO t1 (dateposted) VALUES ( NOW() )
// Yes, you use the same NOW() without the quotes.
// Because your datatype is set to DATE it will insert only the date

$dt = date('Y-m-d');
INSERT INTO t1 (dateposted) VALUES ( '$dt' )
// This will insert date into the col using php var.

TIME (datatype)

INSERT INTO t1 (dateposted) VALUES ( NOW() )
// Yes, you use the same NOW() as well. 
// Because your datatype is set to TIME it will insert only the time

$dt = date('h:i:s');
INSERT INTO t1 (dateposted) VALUES ( '$dt' )
// This will insert time.

I usually use AtomicInteger when I need to give Ids to objects that can be accesed or created from multiple threads, and i usually use it as an static attribute on the class that i access in the constructor of the objects.

Usually it is a simple as adding apply plugin: "eclipse" in your build.gradle and running

cd myProject/
gradle eclipse

and then refreshing your Eclipse project.

Occasionally you'll need to adjust build.gradle to generate Eclipse settings in some very specific way.

There is gradle support for Eclipse if you are using STS, but I'm not sure how good it is.

The only IDE I know that has decent native support for gradle is IntelliJ IDEA. It can do full import of gradle projects from GUI. There is a free Community Edition that you can try.

At the most basic level, something of the form (function(){...})() is a function literal that is executed immediately. What this means is that you have defined a function and you are calling it immediately.

This form is useful for information hiding and encapsulation since anything you define inside that function remains local to that function and inaccessible from the outside world (unless you specifically expose it - usually via a returned object literal).

A variation of this basic form is what you see in jQuery plugins (or in this module pattern in general). Hence:

(function($) {
  ...
})(jQuery);

Which means you're passing in a reference to the actual jQuery object, but it's known as $ within the scope of the function literal.

Type 1 isn't really a plugin. You're simply assigning an object literal to jQuery.fn. Typically you assign a function to jQuery.fn as plugins are usually just functions.

Type 2 is similar to Type 1; you aren't really creating a plugin here. You're simply adding an object literal to jQuery.fn.

Type 3 is a plugin, but it's not the best or easiest way to create one.

To understand more about this, take a look at this similar question and answer. Also, this page goes into some detail about authoring plugins.

For people not wanting a complicated answer, I used Ng-If to solve this for something similar:

<div style="text-align: center;">
 <a ng-if="ctrl.something != null" href="#" ng-click="ctrl.anchorClicked();">I'm An Anchor</a>
 <span ng-if="ctrl.something == null">I'm just text</span>
</div>

Why it can be good to store pictures in the database an not in a catalog on the web server.

You have made an application with lots of pictures stored in a folder on the server, that the client has used for years.

Now they come to you. They server has been destroyed and they need to restore it on a new server. They have no access to the old server anymore. The only backup they have is the database backup.

You have of course the source and can simple deploy it to the new server, install SqlServer and restore the database. But now all the pictures are gone.

If you have saved the pictures in SqlServer everything will work as before.

Just my 2 cents.

This is really strange... Once set, the default Charset is cached and it isn't changed while the class is in memory. Setting the "file.encoding" property with System.setProperty("file.encoding", "Latin-1"); does nothing. Every time Charset.defaultCharset() is called it returns the cached charset.

Here are my results:

Default Charset=ISO-8859-1
file.encoding=Latin-1
Default Charset=ISO-8859-1
Default Charset in Use=ISO8859_1

I'm using JVM 1.6 though.

(update)

Ok. I did reproduce your bug with JVM 1.5.

Looking at the source code of 1.5, the cached default charset isn't being set. I don't know if this is a bug or not but 1.6 changes this implementation and uses the cached charset:

JVM 1.5:

public static Charset defaultCharset() {
    synchronized (Charset.class) {
        if (defaultCharset == null) {
            java.security.PrivilegedAction pa =
                    new GetPropertyAction("file.encoding");
            String csn = (String) AccessController.doPrivileged(pa);
            Charset cs = lookup(csn);
            if (cs != null)
                return cs;
            return forName("UTF-8");
        }
        return defaultCharset;
    }
}

JVM 1.6:

public static Charset defaultCharset() {
    if (defaultCharset == null) {
        synchronized (Charset.class) {
            java.security.PrivilegedAction pa =
                    new GetPropertyAction("file.encoding");
            String csn = (String) AccessController.doPrivileged(pa);
            Charset cs = lookup(csn);
            if (cs != null)
                defaultCharset = cs;
            else
                defaultCharset = forName("UTF-8");
        }
    }
    return defaultCharset;
}

When you set the file encoding to file.encoding=Latin-1 the next time you call Charset.defaultCharset(), what happens is, because the cached default charset isn't set, it will try to find the appropriate charset for the name Latin-1. This name isn't found, because it's incorrect, and returns the default UTF-8.

As for why the IO classes such as OutputStreamWriter return an unexpected result,
the implementation of sun.nio.cs.StreamEncoder (witch is used by these IO classes) is different as well for JVM 1.5 and JVM 1.6. The JVM 1.6 implementation is based in the Charset.defaultCharset() method to get the default encoding, if one is not provided to IO classes. The JVM 1.5 implementation uses a different method Converters.getDefaultEncodingName(); to get the default charset. This method uses its own cache of the default charset that is set upon JVM initialization:

JVM 1.6:

public static StreamEncoder forOutputStreamWriter(OutputStream out,
        Object lock,
        String charsetName)
        throws UnsupportedEncodingException
{
    String csn = charsetName;
    if (csn == null)
        csn = Charset.defaultCharset().name();
    try {
        if (Charset.isSupported(csn))
            return new StreamEncoder(out, lock, Charset.forName(csn));
    } catch (IllegalCharsetNameException x) { }
    throw new UnsupportedEncodingException (csn);
}

JVM 1.5:

public static StreamEncoder forOutputStreamWriter(OutputStream out,
        Object lock,
        String charsetName)
        throws UnsupportedEncodingException
{
    String csn = charsetName;
    if (csn == null)
        csn = Converters.getDefaultEncodingName();
    if (!Converters.isCached(Converters.CHAR_TO_BYTE, csn)) {
        try {
            if (Charset.isSupported(csn))
                return new CharsetSE(out, lock, Charset.forName(csn));
        } catch (IllegalCharsetNameException x) { }
    }
    return new ConverterSE(out, lock, csn);
}

But I agree with the comments. You shouldn't rely on this property. It's an implementation detail.

JJWT aims to be the easiest to use and understand JWT library for the JVM and Android:

https://github.com/jwtk/jjwt

The problem

IE<=8 simply doesn't have an indexOf() method for arrays.

The solution

If you need indexOf in IE<=8, you should consider using the following polyfill, which is recommended at the MDN :

if (!Array.prototype.indexOf) {
    Array.prototype.indexOf = function(searchElement, fromIndex) {
        var k;
        if (this == null) {
            throw new TypeError('"this" is null or not defined');
        }
        var o = Object(this);
        var len = o.length >>> 0;
        if (len === 0) {
            return -1;
        }
        var n = +fromIndex || 0;
        if (Math.abs(n) === Infinity) {
            n = 0;
        }
        if (n >= len) {
            return -1;
        }
        k = Math.max(n >= 0 ? n : len - Math.abs(n), 0);
        while (k < len) {
            if (k in o && o[k] === searchElement) {
                return k;
            }
            k++;
        }
        return -1;
    };
}

Minified :

Array.prototype.indexOf||(Array.prototype.indexOf=function(r,t){var n;if(null==this)throw new TypeError('"this" is null or not defined');var e=Object(this),i=e.length>>>0;if(0===i)return-1;var a=+t||0;if(Math.abs(a)===1/0&&(a=0),a>=i)return-1;for(n=Math.max(a>=0?a:i-Math.abs(a),0);i>n;){if(n in e&&e[n]===r)return n;n++}return-1});

Best avoid casting by declaring f to be f the correct type to correspond to the JSON.

Add following attribute to the element you want to have dotted line.

style="border-bottom: 1px dotted #ff0000;"

Apache is an HTTP web server which serve as HTTP.

Apache Tomcat is a java servlet container. It features same as web server but is customized to execute java servlet and JSP pages.

Add the column and update all rows in the DataTable, for example:

DataTable tbl = new DataTable();
tbl.Columns.Add(new DataColumn("ID", typeof(Int32)));
tbl.Columns.Add(new DataColumn("Name", typeof(string)));
for (Int32 i = 1; i <= 10; i++) {
    DataRow row = tbl.NewRow();
    row["ID"] = i;
    row["Name"] = i + ". row";
    tbl.Rows.Add(row);
}
DataColumn newCol = new DataColumn("NewColumn", typeof(string));
newCol.AllowDBNull = true;
tbl.Columns.Add(newCol);
foreach (DataRow row in tbl.Rows) {
    row["NewColumn"] = "You DropDownList value";
}
//if you don't want to allow null-values'
newCol.AllowDBNull = false;

Use the Javascript string split() function.

var coolVar = '123-abc-itchy-knee';
var partsArray = coolVar.split('-');

// Will result in partsArray[0] == '123', partsArray[1] == 'abc', etc

jQuery.parseJSON

str = jQuery.parseJSON(str)

Edit. This is provided you have a valid JSON string

When working with 4 large Db2 tables I have not only found the limit but it caused me to look really bad to a boss who thought that I could append all four tables (each with over 900,000 rows) to one large table. the real life result was that regardless of how many times I tried the Table (which had exactly 34 columns - 30 text and 3 integer) would spit out some cryptic message "Cannot open database unrecognized format or the file may be corrupted". Bottom Line is Less than 1,500,000 records and just a bit more than 1,252,000 with 34 rows.

For increased performance you should not evaluate the dataframe using your predicate. You can just use the outcome of your predicate directly as illustrated below:

        import numpy as np
        df = pd.DataFrame(np.random.randn(20,4),columns=list('ABCD'))


In [2]: df.head()

Keep in mind that this technique only works for counting the number of rows that comply with your predicate.

The only way that works for me (extracted from here):

chmod a+x name_of_file.bin

Then run it by writing

./name_of_file.bin

If you get a permission error you might have to launch your application with root privileges:

 sudo ./name_of_file.bin

Inspired by VB.Net Generics List(Of Integer), I created my own module for that. Maybe you find it useful, too or you'd like to extend for additional methods e.g. to remove items again:

'Save module with name: ListOfInteger

Public Function ListLength(list() As Integer) As Integer
On Error Resume Next
ListLength = UBound(list) + 1
On Error GoTo 0
End Function

Public Sub ListAdd(list() As Integer, newValue As Integer)
ReDim Preserve list(ListLength(list))
list(UBound(list)) = newValue
End Sub

Public Function ListContains(list() As Integer, value As Integer) As Boolean
ListContains = False
Dim MyCounter As Integer
For MyCounter = 0 To ListLength(list) - 1
    If list(MyCounter) = value Then
        ListContains = True
        Exit For
    End If
Next
End Function

Public Sub DebugOutputList(list() As Integer)
Dim MyCounter As Integer
For MyCounter = 0 To ListLength(list) - 1
    Debug.Print list(MyCounter)
Next
End Sub

You might use it as follows in your code:

Public Sub IntegerListDemo_RowsOfAllSelectedCells()
Dim rows() As Integer

Set SelectedCellRange = Excel.Selection
For Each MyCell In SelectedCellRange
    If IsEmpty(MyCell.value) = False Then
        If ListOfInteger.ListContains(rows, MyCell.Row) = False Then
            ListAdd rows, MyCell.Row
        End If
    End If
Next
ListOfInteger.DebugOutputList rows

End Sub

If you need another list type, just copy the module, save it at e.g. ListOfLong and replace all types Integer by Long. That's it :-)

You can create the ordered dict from old dict in one line:

from collections import OrderedDict
ordered_dict = OrderedDict(sorted(ship.items())

The default sorting key is by dictionary key, so the new ordered_dict is sorted by old dict's keys.

You are probably trying to create a foreign key in some table which exists with the same name in previously existing tables. Use the following format to name your foreign key

tablename_columnname_fk

try to write a shell script named run.sh in your project foler

#!/bin/bash
./YOUR_EXECUTIVE_FILE
...AND OTHER THING

and make a Build System to compile and execute it:

{
      "shell_cmd": "make all && ./run.sh"
}

don't forget $chmod +x run.sh

do one thing and do it well:)

I discovered that this behaviour only occurs after running a particular script, similar to the one in the question. I have no idea why it occurs.

It works (refreshes the graphs) if I put

plt.clf()
plt.cla()
plt.close()

after every plt.show()

You have to use the FormulaEvaluator, as shown here. This will return a value that is either the value present in the cell or the result of the formula if the cell contains such a formula :

FileInputStream fis = new FileInputStream("/somepath/test.xls");
Workbook wb = new HSSFWorkbook(fis); //or new XSSFWorkbook("/somepath/test.xls")
Sheet sheet = wb.getSheetAt(0);
FormulaEvaluator evaluator = wb.getCreationHelper().createFormulaEvaluator();

// suppose your formula is in B3
CellReference cellReference = new CellReference("B3"); 
Row row = sheet.getRow(cellReference.getRow());
Cell cell = row.getCell(cellReference.getCol()); 

if (cell!=null) {
    switch (evaluator.evaluateFormulaCell(cell)) {
        case Cell.CELL_TYPE_BOOLEAN:
            System.out.println(cell.getBooleanCellValue());
            break;
        case Cell.CELL_TYPE_NUMERIC:
            System.out.println(cell.getNumericCellValue());
            break;
        case Cell.CELL_TYPE_STRING:
            System.out.println(cell.getStringCellValue());
            break;
        case Cell.CELL_TYPE_BLANK:
            break;
        case Cell.CELL_TYPE_ERROR:
            System.out.println(cell.getErrorCellValue());
            break;

        // CELL_TYPE_FORMULA will never occur
        case Cell.CELL_TYPE_FORMULA: 
            break;
    }
}

if you need the exact contant (ie the formla if the cell contains a formula), then this is shown here.

Edit : Added a few example to help you.

first you get the cell (just an example)

Row row = sheet.getRow(rowIndex+2);    
Cell cell = row.getCell(1);   

If you just want to set the value into the cell using the formula (without knowing the result) :

 String formula ="ABS((1-E"+(rowIndex + 2)+"/D"+(rowIndex + 2)+")*100)";    
 cell.setCellFormula(formula);    
 cell.setCellStyle(this.valueRightAlignStyleLightBlueBackground);

if you want to change the message if there is an error in the cell, you have to change the formula to do so, something like

IF(ISERR(ABS((1-E3/D3)*100));"N/A"; ABS((1-E3/D3)*100))

(this formula check if the evaluation return an error and then display the string "N/A", or the evaluation if this is not an error).

if you want to get the value corresponding to the formula, then you have to use the evaluator.

Hope this help,

Using c-promise2 lib the cancellable fetch with timeout might look like this one (Live jsfiddle demo):

import CPromise from "c-promise2"; // npm package

function fetchWithTimeout(url, {timeout, ...fetchOptions}= {}) {
    return new CPromise((resolve, reject, {signal}) => {
        fetch(url, {...fetchOptions, signal}).then(resolve, reject)
    }, timeout)
}
        
const chain = fetchWithTimeout("https://run.mocky.io/v3/753aa609-65ae-4109-8f83-9cfe365290f0?mocky-delay=10s", {timeout: 5000})
    .then(request=> console.log('done'));
    
// chain.cancel(); - to abort the request before the timeout

This code as a npm package cp-fetch

PHP's DateTime object is pretty flexible.

$UTC = new DateTimeZone("UTC");
$newTZ = new DateTimeZone("America/New_York");
$date = new DateTime( "2011-01-01 15:00:00", $UTC );
$date->setTimezone( $newTZ );
echo $date->format('Y-m-d H:i:s');

Next to the great answer by @pimvdb, and just in case you where wondering, async.js does not offer truly asynchronous functions either. Here is a (very) stripped down version of the library's main method:

function asyncify(func) { // signature: func(array)
    return function (array, callback) {
        var result;
        try {
            result = func.apply(this, array);
        } catch (e) {
            return callback(e);
        }
        /* code ommited in case func returns a promise */
        callback(null, result);
    };
}

So the function protects from errors and gracefully hands it to the callback to handle, but the code is as synchronous as any other JS function.

This is how we do it in our application

def store_location
  session[:return_to] = request.fullpath if request.get? and controller_name != "user_sessions" and controller_name != "sessions"
end

def redirect_back_or_default(default)
  redirect_to(session[:return_to] || default)
end

This way you only store last GET request in :return_to session param, so all forms, even when multiple time POSTed would work with :return_to.

SELECT TIMESTAMPDIFF(SECOND,'2018-01-19 14:17:15','2018-01-20 14:17:15');

Second approach

SELECT ( DATEDIFF('1993-02-20','1993-02-19')*( 24*60*60) )AS 'seccond';

CURRENT_TIME() --this will return current Date
DATEDIFF('','') --this function will return  DAYS and in 1 day there are 24hh 60mm 60sec

Try calling setWillNotDraw(false) from surfaceCreated:

public void surfaceCreated(SurfaceHolder holder) {
    try {
        setWillNotDraw(false); 
        mycam.setPreviewDisplay(holder);
        mycam.startPreview();
    } catch (Exception e) {
        e.printStackTrace();
        Log.d(TAG,"Surface not created");
    }
}

@Override
protected void onDraw(Canvas canvas) {

    canvas.drawRect(area, rectanglePaint);
    Log.w(this.getClass().getName(), "On Draw Called");
}

and calling invalidate from onTouchEvent:

public boolean onTouch(View v, MotionEvent event) {

    invalidate();
    return true;
}

I am not seeing the importance of the virtual key word here. b is a static-typed variable, and its type is determined by compiler at compile time. The function calls would not reference the vtable. When b is constructed, its parent class's constructor is called, which is why the value of _n is set to 1.

just use SnackBar(content: Text("hello"),) inside any event like onTap and onPress

you can read more about Snackbar here https://flutter.dev/docs/cookbook/design/snackbars

You should find the 'expect' command will do what you need it to do. Its widely available. See here for an example : http://www.thegeekstuff.com/2010/10/expect-examples/

(very rough example)

#!/usr/bin/expect
set pass "mysecret"

spawn /usr/bin/passwd

expect "password: "
send "$pass"
expect "password: "
send "$pass"

If your JSON is without key you can do it like this:

library[library.length] = {"foregrounds" : foregrounds,"backgrounds" : backgrounds};

So, try this:

var library = {[{
    "title"       : "Gold Rush",
        "foregrounds" : ["Slide 1","Slide 2","Slide 3"],
        "backgrounds" : ["1.jpg","","2.jpg"]
    }, {
    "title"       : California",
        "foregrounds" : ["Slide 1","Slide 2","Slide 3"],
        "backgrounds" : ["3.jpg","4.jpg","5.jpg"]
    }]
}

Then:

library[library.length] = {"title" : "Gold Rush", "foregrounds" : ["Howdy","Slide 2"], "backgrounds" : ["1.jpg",""]};

Just use the shells "set" built-in. For example,

set $text

After that, individual words in $text will be in $1, $2, $3, etc. For robustness, one usually does

set -- junk $text
shift

to handle the case where $text is empty or start with a dash. For example:

text="This is          a              test"
set -- junk $text
shift
for word; do
  echo "[$word]"
done

This prints

[This]
[is]
[a]
[test]

public static extern int FindWindow(string lpClassName, String lpWindowName);

In order to find the window, you need the class name of the window. Here are some examples:

C#:

const string lpClassName = "Winamp v1.x";
IntPtr hwnd = FindWindow(lpClassName, null);

Example from a program that I made, written in VB:

hParent = FindWindow("TfrmMain", vbNullString)

In order to get the class name of a window, you'll need something called Win Spy

Once you have the handle of the window, you can send messages to it using the SendMessage(IntPtr hWnd, int wMsg, IntPtr wParam, IntPtr lParam) function.

hWnd, here, is the result of the FindWindow function. In the above examples, this will be hwnd and hParent. It tells the SendMessage function which window to send the message to.

The second parameter, wMsg, is a constant that signifies the TYPE of message that you are sending. The message might be a keystroke (e.g. send "the enter key" or "the space bar" to a window), but it might also be a command to close the window (WM_CLOSE), a command to alter the window (hide it, show it, minimize it, alter its title, etc.), a request for information within the window (getting the title, getting text within a text box, etc.), and so on. Some common examples include the following:

Public Const WM_CHAR = &H102
Public Const WM_SETTEXT = &HC
Public Const WM_KEYDOWN = &H100
Public Const WM_KEYUP = &H101
Public Const WM_LBUTTONDOWN = &H201
Public Const WM_LBUTTONUP = &H202
Public Const WM_CLOSE = &H10
Public Const WM_COMMAND = &H111
Public Const WM_CLEAR = &H303
Public Const WM_DESTROY = &H2
Public Const WM_GETTEXT = &HD
Public Const WM_GETTEXTLENGTH = &HE
Public Const WM_LBUTTONDBLCLK = &H203

These can be found with an API viewer (or a simple text editor, such as notepad) by opening (Microsoft Visual Studio Directory)/Common/Tools/WINAPI/winapi32.txt.

The next two parameters are certain details, if they are necessary. In terms of pressing certain keys, they will specify exactly which specific key is to be pressed.

C# example, setting the text of windowHandle with WM_SETTEXT:

x = SendMessage(windowHandle, WM_SETTEXT, new IntPtr(0), m_strURL);

More examples from a program that I made, written in VB, setting a program's icon (ICON_BIG is a constant which can be found in winapi32.txt):

Call SendMessage(hParent, WM_SETICON, ICON_BIG, ByVal hIcon)

Another example from VB, pressing the space key (VK_SPACE is a constant which can be found in winapi32.txt):

Call SendMessage(button%, WM_KEYDOWN, VK_SPACE, 0)
Call SendMessage(button%, WM_KEYUP, VK_SPACE, 0)

VB sending a button click (a left button down, and then up):

Call SendMessage(button%, WM_LBUTTONDOWN, 0, 0&)
Call SendMessage(button%, WM_LBUTTONUP, 0, 0&)

No idea how to set up the listener within a .DLL, but these examples should help in understanding how to send the message.

All of the example above should work just add a document ready action and change the order of how you perform the updates to the texts, also make sure your using Script manager alternatively non of this will work for you. Here is the text within the code behind.

For me, the node binary is in PATH and I can run it from the terminal (iTerm or Terminal), and the Terminal apps are set to use zsh

If you are on a Mac, with iTerm and Zsh, please use the following VSCode settings for Node to work.

After this change, you can get rid of this line from your launch.json config file. (the debug settings in VSCode)

    "runtimeExecutable": "/usr/local/bin/node"

If this doesn't work, make sure you choose the default shell as zsh. To do this,

• Open the command palette using Cmd+Shift+P

• Look for the Terminal: Select Default Shell command

• Select zsh from the options

I'd go for purchase-rest-service. Reasons:

1. What is "pur chase rests ervice"? Long, concatenated words are hard to understand. I know, I'm German. "Donaudampfschifffahrtskapitänspatentausfüllungsassistentenausschreibungsstellenbewerbung."

2. "_" is harder to type than "-"

You should add first jquery.cookie.js then add your js or jQuery where you are using that function.

How to restore a database from backup using SQL Server Management Studio 2019

If you have SQL Server Management Studio installed, you can restore database backup using its interface alone. Just follow the instructions:

1. Connect to your SQL Server and right-click on the “Databases” directory and choose “Restore Database”
for more info follow the below link
https://sqlbackupandftp.com/blog/restore-database-backup

suppose your JAR file is in C:\Documents and Settings\mmeher\Desktop\jar and the JAR file name is xx.jar, then write the below two commands in command prompt:

1> cd C:\Documents and Settings\mmeher\Desktop\jar

2> jar xf xx.jar

This is the syntax of creating primary key

db.< collection >.createIndex( < key and index type specification>, { unique: true } )

Let's take that our database have collection named student and it's document have key named student_id which we need to make a primary key. Then the command should be like below.

db.student.createIndex({student_id:1},{unique:true})

You can check whether this student_id set as primary key by trying to add duplicate value to the student collection.

Messing around with the same answers:

$ git config --global alias.find '!git log --color -p -S '

• ! is needed because other way, git do not pass argument correctly to -S. See this response
• --color and -p helps to show exactly "whatchanged"

Now you can do

$ git find <whatever>

or

$ git find <whatever> --all
$ git find <whatever> master develop

In the context of data storage, serialization (or serialisation) is the process of translating data structures or object state into a format that can be stored (for example, in a file or memory buffer) or transmitted (for example, across a network connection link) and reconstructed later. [...]
The opposite operation, extracting a data structure from a series of bytes, is deserialization. From Wikipedia

In Python "serialization" does nothing else than just converting the given data structure (e.g. a dict) into its valid JSON pendant (object).

• Python's True will be converted to JSONs true and the dictionary itself will then be encapsulated in quotes.
• You can easily spot the difference between a Python dictionary and JSON by their Boolean values:
  • Python: True / False,
  • JSON: true / false
• Python builtin module json is the standard way to do serialization:

Code example:

data = {
    "president": {
        "name": "Zaphod Beeblebrox",
        "species": "Betelgeusian",
        "male": True,
    }
}

import json
json_data = json.dumps(data, indent=2) # serialize
restored_data = json.loads(json_data) # deserialize

# serialized json_data now looks like:
# {
#   "president": {
#     "name": "Zaphod Beeblebrox",
#     "species": "Betelgeusian",
#     "male": true
#   }
# }

Try using ,

$('#points').val(request.responseText);

$('#myTable tr').click(function(){
    $(this).remove();
    return false;
});

Even a better one

$("#MyTable").on("click", "#DeleteButton", function() {
   $(this).closest("tr").remove();
});

In addition to the accepted answer, I want to give you an example!

For instance, we all use

System.Console.WriteLine()

But Where is the code for System.Console.WriteLine!?
which is the code that actually puts the text on the console?

If you look at the first page of the documentation for the Console class, you‘ll see near the top the following: Assembly: mscorlib (in mscorlib.dll) This indicates that the code for the Console class is located in an assem-bly named mscorlib. An assembly can consist of multiple files, but in this case it‘s only one file, which is the dynamic link library mscorlib.dll.

The mscorlib.dll file is very important in .NET, It is the main DLL for class libraries in .NET, and it contains all the basic .NET classes and structures.

if you know C or C++, generally you need a #include directive at the top that references a header file. The include file provides function prototypes to the compiler. on the contrast The C# compiler does not need header files. During compilation, the C# compiler access the mscorlib.dll file directly and obtains information from metadata in that file concerning all the classes and other types defined therein.

The C# compiler is able to establish that mscorlib.dll does indeed contain a class named Console in a namespace named System with a method named WriteLine that accepts a single argument of type string.

The C# compiler can determine that the WriteLine call is valid, and the compiler establishes a reference to the mscorlib assembly in the executable.

by default The C# compiler will access mscorlib.dll, but for other DLLs, you‘ll need to tell the compiler the assembly in which the classes are located. These are known as references.

I hope that it's clear now!

For example: Add this data-attr to your primary slick div: data-space="7"

                    $('[data-space]').each(function () {
                        var $this = $(this),
                            $space = $this.attr('data-space');

                        $('.slick-slide').css({
                            marginLeft: $space + 'px',
                            marginRight: $space + 'px'
                        });

                        $('.slick-list').css({
                            marginLeft: -$space + 'px',
                            marginRight: -$space/2 + 'px'
                        })
                    });

Use any examples that don't insert each element one at a time, one insertion is most efficient

 $('.element').html( '<span>' + array.join('</span><span>')+'</span>');

For those of us who did not see -1 by Michal Chaniewski, the complete line of code:

cmd.Parameters.Add("@blah",SqlDbType.VarChar,-1).Value = "some large text";

in php line breaks we can use PHP_EOL (END of LINE) .it working as "\n" but it cannot be shown on the ht ml page .because we have to give HTML break to break the Line..

so you can use it using define

define ("EOL","<br>");

then you can call it

Very simple, no library required:

var date = new Date();
var firstDay = new Date(date.getFullYear(), date.getMonth(), 1);
var lastDay = new Date(date.getFullYear(), date.getMonth() + 1, 0);

or you might prefer:

var date = new Date(), y = date.getFullYear(), m = date.getMonth();
var firstDay = new Date(y, m, 1);
var lastDay = new Date(y, m + 1, 0);

EDIT

Some browsers will treat two digit years as being in the 20th century, so that:

new Date(14, 0, 1);

gives 1 January, 1914. To avoid that, create a Date then set its values using setFullYear:

var date = new Date();
date.setFullYear(14, 0, 1); // 1 January, 14

If BranchA has not been pushed to a remote then you can reorder the commits using rebase and then simply merge. It's preferable to use merge over rebase when possible because it doesn't create duplicate commits.

git checkout BranchA
git rebase -i HEAD~113
... reorder the commits so the 10 you want are first ...
git checkout BranchB
git merge [the 10th commit]

Here is the small example

public class TryWithResource {

    public static void main(String[] args) {
        try (TestMe r = new TestMe()) {
            r.generalTest();
        } catch(Exception e) {
            System.out.println("From Exception Block");
        } finally {
            System.out.println("From Final Block");
        }
    }
}



public class TestMe implements AutoCloseable {

    @Override
    public void close() throws Exception {
        System.out.println(" From Close -  AutoCloseable  ");
    }

    public void generalTest() {
        System.out.println(" GeneralTest ");
    }
}

Here is the output:

GeneralTest 
From Close -  AutoCloseable  
From Final Block

You can use find

find . -type d > output.txt

or tree

tree -d > output.txt

tree, If not installed on your system.

If you are using ubuntu

sudo apt-get install tree

If you are using mac os.

brew install tree

I had some strings in the MongoDB Stored wich had to be reformated to a proper and valid dateTime field in the mongodb.

here is my code for the special date format: "2014-03-12T09:14:19.5303017+01:00"

but you can easyly take this idea and write your own regex to parse the date formats:

// format: "2014-03-12T09:14:19.5303017+01:00"
var myregexp = /(....)-(..)-(..)T(..):(..):(..)\.(.+)([\+-])(..)/;

db.Product.find().forEach(function(doc) { 
   var matches = myregexp.exec(doc.metadata.insertTime);

   if myregexp.test(doc.metadata.insertTime)) {
       var offset = matches[9] * (matches[8] == "+" ? 1 : -1);
       var hours = matches[4]-(-offset)+1
       var date = new Date(matches[1], matches[2]-1, matches[3],hours, matches[5], matches[6], matches[7] / 10000.0)
       db.Product.update({_id : doc._id}, {$set : {"metadata.insertTime" : date}})
       print("succsessfully updated");
    } else {
        print("not updated");
    }
})

How you test depends on the Property's DataType:

| Type                                 | Test                            | Test2
| Numeric (Long, Integer, Double etc.) | If obj.Property = 0 Then        | 
| Boolen (True/False)                  | If Not obj.Property Then        | If obj.Property = False Then
| Object                               | If obj.Property Is Nothing Then |
| String                               | If obj.Property = "" Then       | If LenB(obj.Property) = 0 Then
| Variant                              | If obj.Property = Empty Then    |

You can tell the DataType by pressing F2 to launch the Object Browser and looking up the Object. Another way would be to just use the TypeName function:MsgBox TypeName(obj.Property)

A standard http GET request should do it. Then you can use JSON.parse() to make it into a json object.

function Get(yourUrl){
    var Httpreq = new XMLHttpRequest(); // a new request
    Httpreq.open("GET",yourUrl,false);
    Httpreq.send(null);
    return Httpreq.responseText;          
}

then

var json_obj = JSON.parse(Get(yourUrl));
console.log("this is the author name: "+json_obj.author_name);

that's basically it

for plesk hosts, one of these should do: (both do the same)

mysqlrepair -uadmin -p$(cat /etc/psa/.psa.shadow) -A
# or
mysqlcheck -uadmin -p$(cat /etc/psa/.psa.shadow) --repair -A

You should be looking for the second tr that has the td that equals ' Color Digest ', then you need to look at either the following sibling of the first td in the tr, or the second td.

Try the following:

//tr[td='Color Digest'][2]/td/following-sibling::td[1]

or

//tr[td='Color Digest'][2]/td[2]

there is a cross browser script for get parent origin:

private getParentOrigin() {
  const locationAreDisctint = (window.location !== window.parent.location);
  const parentOrigin = ((locationAreDisctint ? document.referrer : document.location) || "").toString();

  if (parentOrigin) {
    return new URL(parentOrigin).origin;
  }

  const currentLocation = document.location;

  if (currentLocation.ancestorOrigins && currentLocation.ancestorOrigins.length) {
    return currentLocation.ancestorOrigins[0];
  }

  return "";
}

This code, should work on Chrome and Firefox.

When a folder is created, many Linux filesystems allocate 4096 bytes to store some metadata about the directory itself. This space is increased by a multiple of 4096 bytes as the directory grows.

du command (with or without -b option) take in count this space, as you can see typing:

mkdir test && du -b test

you will have a result of 4096 bytes for an empty dir. So, if you put 2 files of 10000 bytes inside the dir, the total amount given by du -sb would be 24096 bytes.

If you read carefully the question, this is not what asked. The questioner asked:

the sum total of all the data in files and subdirectories I would get if I opened each file and counted the bytes

that in the example above should be 20000 bytes, not 24096.

So, the correct answer IMHO could be a blend of Nelson answer and hlovdal suggestion to handle filenames containing spaces:

find . -type f -print0 | xargs -0 stat --format=%s | awk '{s+=$1} END {print s}'

Another thing to watch out for is double backslashes, since xcopy does not tolerate them in the input path parameter (but it does tolerate them in the output path...).

Check your server config file /etc/mysql/my.cnf - verify bind_address is not set to 127.0.0.1. Set it to 0.0.0.0 or comment it out then restart server with:

sudo service mysql restart

Look at the WAITFOR command.

E.g.

-- wait for 1 minute
WAITFOR DELAY '00:01'

-- wait for 1 second
WAITFOR DELAY '00:00:01'

This command allows you a high degree of precision but is only accurate within 10ms - 16ms on a typical machine as it relies on GetTickCount. So, for example, the call WAITFOR DELAY '00:00:00:001' is likely to result in no wait at all.

I had the same sittuation , I had many buttongroup insite my item on listview and I was changing some boolean values inside my item like holder.rbVar.setOnclik...

my problem occured because I was calling a method inside getView(); and was saving an object inside sharepreference, so I had same error above

How I solved it; I removed my method inside getView() to notifyDataSetInvalidated() and problem gone

   @Override
    public void notifyDataSetChanged() {
        saveCurrentTalebeOnShare(currentTalebe);
        super.notifyDataSetChanged();
    }

string result = arr.Aggregate("", (s, i) => s + i.ToString());

(Disclaimer: If you have a lot of digits (hundreds, at least) and you care about performance, I suggest eschewing this method and using a StringBuilder, as in JaredPar's answer.)
