A slight change to Thangamani Palanisamy answer, which allows the Binary reader to be disposed and corrects the input length issue in his comments.

string result = string.Empty;

using (BinaryReader b = new BinaryReader(file.InputStream))
{
  byte[] binData = b.ReadBytes(file.ContentLength);
  result = System.Text.Encoding.UTF8.GetString(binData);
}

You want:

document.cookie = cookieName +"=" + cookieValue + ";domain=.example.com;path=/;expires=" + myDate;

As per the RFC 2109, to have a cookie available to all subdomains, you must put a . in front of your domain.

Setting the path=/ will have the cookie be available within the entire specified domain(aka .example.com).

What exactly do you want to know? ActiveRecord has methods that serialize records into JSON. For instance, open up your rails console and enter ModelName.all.to_json and you will see JSON output. render :json essentially calls to_json and returns the result to the browser with the correct headers. This is useful for AJAX calls in JavaScript where you want to return JavaScript objects to use. Additionally, you can use the callback option to specify the name of the callback you would like to call via JSONP.

For instance, lets say we have a User model that looks like this: {name: 'Max', email:' [email protected]'}

We also have a controller that looks like this:

class UsersController < ApplicationController
    def show
        @user = User.find(params[:id])
        render json: @user
    end
end

Now, if we do an AJAX call using jQuery like this:

$.ajax({
    type: "GET",
    url: "/users/5",
    dataType: "json",
    success: function(data){
        alert(data.name) // Will alert Max
    }        
});

As you can see, we managed to get the User with id 5 from our rails app and use it in our JavaScript code because it was returned as a JSON object. The callback option just calls a JavaScript function of the named passed with the JSON object as the first and only argument.

To give an example of the callback option, take a look at the following:

class UsersController < ApplicationController
    def show
        @user = User.find(params[:id])
        render json: @user, callback: "testFunction"
    end
end

Now we can crate a JSONP request as follows:

function testFunction(data) {
    alert(data.name); // Will alert Max
};

var script = document.createElement("script");
script.src = "/users/5";

document.getElementsByTagName("head")[0].appendChild(script);

The motivation for using such a callback is typically to circumvent the browser protections that limit cross origin resource sharing (CORS). JSONP isn't used that much anymore, however, because other techniques exist for circumventing CORS that are safer and easier.

Yes you can do this.

*[id^='term-']{
    [css here]
}

This will select all ids that start with 'term-'.

As for the reason for not doing this, I see where it would be preferable to select this way; as for style, I wouldn't do it myself, but it's possible.

Without using lambda:

from operator import mul
reduce(mul, list, 1)

it is better and faster. With python 2.7.5

from operator import mul
import numpy as np
import numexpr as ne
# from functools import reduce # python3 compatibility

a = range(1, 101)
%timeit reduce(lambda x, y: x * y, a)   # (1)
%timeit reduce(mul, a)                  # (2)
%timeit np.prod(a)                      # (3)
%timeit ne.evaluate("prod(a)")          # (4)

In the following configuration:

a = range(1, 101)  # A
a = np.array(a)    # B
a = np.arange(1, 1e4, dtype=int) #C
a = np.arange(1, 1e5, dtype=float) #D

Results with python 2.7.5

       |     1     |     2     |     3     |     4     |
-------+-----------+-----------+-----------+-----------+
 A       20.8 µs     13.3 µs     22.6 µs     39.6 µs     
 B        106 µs     95.3 µs     5.92 µs     26.1 µs
 C       4.34 ms     3.51 ms     16.7 µs     38.9 µs
 D       46.6 ms     38.5 ms      180 µs      216 µs

Result: np.prod is the fastest one, if you use np.array as data structure (18x for small array, 250x for large array)

with python 3.3.2:

       |     1     |     2     |     3     |     4     |
-------+-----------+-----------+-----------+-----------+
 A       23.6 µs     12.3 µs     68.6 µs     84.9 µs     
 B        133 µs      107 µs     7.42 µs     27.5 µs
 C       4.79 ms     3.74 ms     18.6 µs     40.9 µs
 D       48.4 ms     36.8 ms      187 µs      214 µs

Is python 3 slower?

There is not such notion as "RESTful programming" per se. It would be better called RESTful paradigm or even better RESTful architecture. It is not a programming language. It is a paradigm.

From Wikipedia:

In computing, representational state transfer (REST) is an architectural style used for web development.

There are multiple options available for generating HTML reports for Selenium WebDriver scripts.

1. Use the JUNIT TestWatcher class for creating your own Selenium HTML reports

The TestWatcher JUNIT class allows overriding the failed() and succeeded() JUNIT methods that are called automatically when JUNIT tests fail or pass.

The TestWatcher JUNIT class allows overriding the following methods:

• protected void failed(Throwable e, Description description)

failed() method is invoked when a test fails

• protected void finished(Description description)

finished() method is invoked when a test method finishes (whether passing or failing)

• protected void skipped(AssumptionViolatedException e, Description description)

skipped() method is invoked when a test is skipped due to a failed assumption.

• protected void starting(Description description)

starting() method is invoked when a test is about to start

• protected void succeeded(Description description)

succeeded() method is invoked when a test succeeds

See below sample code for this case:

import static org.junit.Assert.assertTrue;
import org.junit.Test;

public class TestClass2 extends WatchManClassConsole {

    @Test public void testScript1() {
        assertTrue(1 < 2); >
    }

    @Test public void testScript2() {
        assertTrue(1 > 2);
    }

    @Test public void testScript3() {
        assertTrue(1 < 2);
    }

    @Test public void testScript4() {
        assertTrue(1 > 2);
    }
}

import org.junit.Rule; 
import org.junit.rules.TestRule; 
import org.junit.rules.TestWatcher; 
import org.junit.runner.Description; 
import org.junit.runners.model.Statement; 

public class WatchManClassConsole {

    @Rule public TestRule watchman = new TestWatcher() { 

        @Override public Statement apply(Statement base, Description description) { 
            return super.apply(base, description); 
        } 

        @Override protected void succeeded(Description description) { 
            System.out.println(description.getDisplayName() + " " + "success!"); 
        } 

        @Override protected void failed(Throwable e, Description description) { 
            System.out.println(description.getDisplayName() + " " + e.getClass().getSimpleName()); 
        }
    }; 
}

2. Use the Allure Reporting framework

Allure framework can help with generating HTML reports for your Selenium WebDriver projects.

The reporting framework is very flexible and it works with many programming languages and unit testing frameworks.

You can read everything about it at http://allure.qatools.ru/.

You will need the following dependencies and plugins to be added to your pom.xml file

1. maven surefire
2. aspectjweaver
3. allure adapter

See more details including code samples on this article: http://test-able.blogspot.com/2015/10/create-selenium-html-reports-with-allure-framework.html

In the end I made a jQuery plugin that will format the <input type="number" /> appropriately for me. I also noticed on some mobile devices the min and max attributes don't actually prevent you from entering lower or higher numbers than specified, so the plugin will account for that too. Below is the code and an example:

(function($) {_x000D_
  $.fn.currencyInput = function() {_x000D_
    this.each(function() {_x000D_
      var wrapper = $("<div class='currency-input' />");_x000D_
      $(this).wrap(wrapper);_x000D_
      $(this).before("<span class='currency-symbol'>$</span>");_x000D_
      $(this).change(function() {_x000D_
        var min = parseFloat($(this).attr("min"));_x000D_
        var max = parseFloat($(this).attr("max"));_x000D_
        var value = this.valueAsNumber;_x000D_
        if(value < min)_x000D_
          value = min;_x000D_
        else if(value > max)_x000D_
          value = max;_x000D_
        $(this).val(value.toFixed(2)); _x000D_
      });_x000D_
    });_x000D_
  };_x000D_
})(jQuery);_x000D_
_x000D_
$(document).ready(function() {_x000D_
  $('input.currency').currencyInput();_x000D_
});

.currency {_x000D_
  padding-left:12px;_x000D_
}_x000D_
_x000D_
.currency-symbol {_x000D_
  position:absolute;_x000D_
  padding: 2px 5px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
<input type="number" class="currency" min="0.01" max="2500.00" value="25.00" />

Looks like you haven't upgraded PHP modules, they are not compatible.

Check extension_dir directive in your php.ini. It should point to folder with 5.2 modules.

Create and open a phpinfo file and search for extension_dir to find the path.

Since you did upgrade, there is a chance that you are using old php.ini that is pointing to 5.1 modules

^\d{5}(?:[-\s]\d{4})?$

• ^ = Start of the string.
• \d{5} = Match 5 digits (for condition 1, 2, 3)
• (?:…) = Grouping
• [-\s] = Match a space (for condition 3) or a hyphen (for condition 2)
• \d{4} = Match 4 digits (for condition 2, 3)
• …? = The pattern before it is optional (for condition 1)
• $ = End of the string.

you can stash the uncommitted changes using "git stash" then checkout to a new branch using "git checkout -b " then apply the stashed commits "git stash apply"

JTextField allows us to getText() and setText() these are used to get and set the contents of the text field, for example.

text = texfield.getText();

hope this helps

Why don't you just right click on the main() method and choose "Debug As... Java Application"?

This is the mysql function using the space technique (tested with mysql 5.0 + 5.5): CREATE FUNCTION count_str( haystack TEXT, needle VARCHAR(32)) RETURNS INTEGER DETERMINISTIC RETURN LENGTH(haystack) - LENGTH( REPLACE ( haystack, needle, space(char_length(needle)-1)) );

Run: python -c "import ssl; print(ssl.get_default_verify_paths())" to check the current paths which are used to verify the certificate. Add your company's root certificate to one of those.

The path openssl_capath_env points to the environment variable: SSL_CERT_DIR.

If SSL_CERT_DIR doesn't exist, you will need to create it and point it to a valid folder within your filesystem. You can then add your certificate to this folder to use it.

This error creeps in if we make some spelling mistake in entering the variable name. Like in stored proc, I have the variable name x and in my insert statement I am using

insert into tablename values(y);

It will throw an error column not allowed here.

There are several ways to do that. But do not just update to the earlier revision as suggested here.

The easiest way to revert the changes from a single revision, or from a range of revisions, is to use the revision log dialog. This is also the method to use of you want to discard recent changes and make an earlier revision the new HEAD.

1. Select the file or folder in which you need to revert the changes. If you want to revert all changes, this should be the top level folder.
2. Select TortoiseSVN ? Show Log to display a list of revisions. You may need to use Show All or Next 100 to show the revision(s) you are interested in.
3. Select the revision you wish to revert. If you want to undo a range of revisions, select the first one and hold Shift while selecting the last one. Note that for multiple revisions, the range must be unbroken with no gaps. Right click on the selected revision(s), then select Context Menu ? Revert changes from this revision.
4. Or if you want to make an earlier revision the new HEAD revision, right click on the selected revision, then select Context Menu ? Revert to this revision. This will discard all changes after the selected revision.

You have reverted the changes within your working copy. Check the results, then commit the changes.

All solutions are explained in the "How Do I..." part of the TortoiseSVN docs.

The Alert Method, authenticateUsing() lets you skip the Http Basic Authentication box.

WebDriverWait wait = new WebDriverWait(driver, 10);      
Alert alert = wait.until(ExpectedConditions.alertIsPresent());     
alert.authenticateUsing(new UserAndPassword(username, password));

As of Selenium 3.4 it is still in beta

Right now implementation is only done for InternetExplorerDriver

The commands from WEFX worked for me after I enabled the parent features RemoteServerAdministrationTools, RemoteServerAdministrationTools-Roles, and RemoteServerAdministrationTools-Roles-AD

Combination from itertools

import itertools
col_names = ["aa","bb", "cc", "dd"]
all_combinations = itertools.chain(*[itertools.combinations(col_names,i+1) for i,_ in enumerate(col_names)])
print(list(all_combinations))

Alternatively, you could invert the image using the bitwise_not function of OpenCV:

imagem = cv2.bitwise_not(imagem)

I liked this example.

You need a back inserter to copy into vectors:

std::copy(str.c_str(), str.c_str()+str.length(), back_inserter(data));

Minimal runnable example

main.cpp

#include <cassert>

class C {
    public:
        int i;
        C(int i) : i(i) {}
        int m(int j) { return this->i + j; }
};

int main() {
    // Get a method pointer.
    int (C::*p)(int) = &C::m;

    // Create a test object.
    C c(1);
    C *cp = &c;

    // Operator .*
    assert((c.*p)(2) == 3);

    // Operator ->*
    assert((cp->*p)(2) == 3);
}

Compile and run:

g++ -ggdb3 -O0 -std=c++11 -Wall -Wextra -pedantic -o main.out main.cpp
./main.out

Tested in Ubuntu 18.04.

You cannot change the order of the parenthesis or omit them. The following do not work:

c.*p(2)
c.*(p)(2)

GCC 9.2 would fail with:

main.cpp: In function ‘int main()’:
main.cpp:19:18: error: must use ‘.*’ or ‘->*’ to call pointer-to-member function in ‘p (...)’, e.g. ‘(... ->* p) (...)’
   19 |     assert(c.*p(2) == 3);
      |

C++11 standard

.* and ->* are a single operators introduced in C++ for this purpose, and not present in C.

C++11 N3337 standard draft:

• 2.13 "Operators and punctuators" has a list of all operators, which contains .* and ->*.
• 5.5 "Pointer-to-member operators" explains what they do

Use typings to access node functions from TypeScript:

typings install env~node --global

If you don't have typings install it:

npm install typings --global

Just use replace instead of replaceAll (which expects regex):

str = str.replace(",", ".");

or

str = str.replace(',', '.');

(replace takes as input either char or CharSequence, which is an interface implemented by String)

Also note that you should reassign the result

only use casting this way:

if((YouEnum)ComboBoxControl.SelectedItem == YouEnum.Español)
{
   //TODO: type you code here
}

Apparently, org.json.simple.JSONArray implements a raw Iterator. This means that each element is considered to be an Object. You can try to cast:

for(Object o: arr){
    if ( o instanceof JSONObject ) {
        parse((JSONObject)o);
    }
}

This is how things were done back in Java 1.4 and earlier.

Using jQuery you can do exactly the same thing, for example:

$("a").click();

Which will "click" all anchors on the page.

PHP has several libraries for XML Manipulation.

The Document Object Model (DOM) approach (which is a W3C standard and should be familiar if you've used it in other environments such as a Web Browser or Java, etc). Allows you to create documents as follows

<?php
    $doc = new DOMDocument( );
    $ele = $doc->createElement( 'Root' );
    $ele->nodeValue = 'Hello XML World';
    $doc->appendChild( $ele );
    $doc->save('MyXmlFile.xml');
?>

Even if you haven't come across the DOM before, it's worth investing some time in it as the model is used in many languages/environments.

To Select an Option Via Text;

(new SelectElement(driver.FindElement(By.XPath(""))).SelectByText("");

To Select an Option via Value:

 (new SelectElement(driver.FindElement(By.XPath(""))).SelectByValue("");

You can also use the regroup template tag to group by attributes. From the docs:

cities = [
    {'name': 'Mumbai', 'population': '19,000,000', 'country': 'India'},
    {'name': 'Calcutta', 'population': '15,000,000', 'country': 'India'},
    {'name': 'New York', 'population': '20,000,000', 'country': 'USA'},
    {'name': 'Chicago', 'population': '7,000,000', 'country': 'USA'},
    {'name': 'Tokyo', 'population': '33,000,000', 'country': 'Japan'},
]

...

{% regroup cities by country as country_list %}

<ul>
    {% for country in country_list %}
        <li>{{ country.grouper }}
            <ul>
            {% for city in country.list %}
                <li>{{ city.name }}: {{ city.population }}</li>
            {% endfor %}
            </ul>
        </li>
    {% endfor %}
</ul>

Looks like this:

• India
  • Mumbai: 19,000,000
  • Calcutta: 15,000,000
• USA
  • New York: 20,000,000
  • Chicago: 7,000,000
• Japan
  • Tokyo: 33,000,000

It also works on QuerySets I believe.

source: https://docs.djangoproject.com/en/2.1/ref/templates/builtins/#regroup

edit: note the regroup tag does not work as you would expect it to if your list of dictionaries is not key-sorted. It works iteratively. So sort your list (or query set) by the key of the grouper before passing it to the regroup tag.

Java Object Serialization

Serialization is a mechanism to transform a graph of Java objects into an array of bytes for storage(to disk file) or transmission(across a network), then by using deserialization we can restore the graph of objects. Graphs of objects are restored correctly using a reference sharing mechanism. But before storing, check whether serialVersionUID from input-file/network and .class file serialVersionUID are the same. If not, throw a java.io.InvalidClassException.

Each versioned class must identify the original class version for which it is capable of writing streams and from which it can read. For example, a versioned class must declare:

serialVersionUID Syntax

// ANY-ACCESS-MODIFIER static final long serialVersionUID = (64-bit has)L;
private static final long serialVersionUID = 3487495895819393L;

serialVersionUID is essential to the serialization process. But it is optional for the developer to add it into the java source file. If a serialVersionUID is not included, the serialization runtime will generate a serialVersionUID and associate it with the class. The serialized object will contain this serialVersionUID along with other data.

Note - It is strongly recommended that all serializable classes explicitly declare a serialVersionUID, since the default serialVersionUID computation is highly sensitive to class details that may vary depending on compiler implementations, and can thus result in unexpected serialVersionUID conflicts during deserialization, causing deserialization to fail.

Inspecting Serializable Classes

A Java object is only serializable. if a class or any of its superclasses implements either the java.io.Serializable interface or its subinterface, java.io.Externalizable.

• A class must implement java.io.Serializable interface in order to serialize its object successfully. Serializable is a marker interface and used to inform the compiler that the class implementing it has to be added serializable behavior. Here Java Virtual Machine (JVM) is responsible for its automatic serialization.

  transient Keyword: java.io.Serializable interface

  While serializing an object, if we don't want certain data members of the object to be serialized we can use the transient modifier. The transient keyword will prevent that data member from being serialized.

  • Fields declared as transient or static are ignored by the serialization process.

  TRANSIENT & VOLATILE

  +--------------+--------+-------------------------------------+
  |  Flag Name   |  Value | Interpretation                      |
  +--------------+--------+-------------------------------------+
  | ACC_VOLATILE | 0x0040 | Declared volatile; cannot be cached.|
  +--------------+--------+-------------------------------------+
  |ACC_TRANSIENT | 0x0080 | Declared transient; not written or  |
  |              |        | read by a persistent object manager.|
  +--------------+--------+-------------------------------------+
  

  class Employee implements Serializable {
      private static final long serialVersionUID = 2L;
      static int id;
  
      int eno; 
      String name;
      transient String password; // Using transient keyword means its not going to be Serialized.
  }
  

• Implementing the Externalizable interface allows the object to assume complete control over the contents and format of the object's serialized form. The methods of the Externalizable interface, writeExternal and readExternal, are called to save and restore the objects state. When implemented by a class they can write and read their own state using all of the methods of ObjectOutput and ObjectInput. It is the responsibility of the objects to handle any versioning that occurs.

  class Emp implements Externalizable {
      int eno; 
      String name;
      transient String password; // No use of transient, we need to take care of write and read.
  
      @Override
      public void writeExternal(ObjectOutput out) throws IOException {
          out.writeInt(eno);
          out.writeUTF(name);
          //out.writeUTF(password);
      }
      @Override
      public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException {
          this.eno = in.readInt();
          this.name = in.readUTF();
          //this.password = in.readUTF(); // java.io.EOFException
      }
  }
  

• Only objects that support the java.io.Serializable or java.io.Externalizable interface can be written to/read from streams. The class of each serializable object is encoded including the class name and signature of the class, the values of the object's fields and arrays, and the closure of any other objects referenced from the initial objects.

Serializable Example For Files

public class SerializationDemo {
    static String fileName = "D:/serializable_file.ser";

    public static void main(String[] args) throws IOException, ClassNotFoundException, InstantiationException, IllegalAccessException {
        Employee emp = new Employee( );

        emp.password = "confidential";
        objects_WriteRead(emp, fileName);

        Emp e = new Emp( );

    }
    public static void objects_WriteRead( Employee obj, String serFilename ) throws IOException{
        FileOutputStream fos = new FileOutputStream( new File( serFilename ) );
        ObjectOutputStream objectOut = new ObjectOutputStream( fos );
        objectOut.writeObject( obj );
        objectOut.close();
        fos.close();

        System.out.println("Data Stored in to a file");

        try {
            FileInputStream fis = new FileInputStream( new File( serFilename ) );
            ObjectInputStream ois = new ObjectInputStream( fis );
            Object readObject;
            readObject = ois.readObject();
            String calssName = readObject.getClass().getName();
            System.out.println("Restoring Class Name : "+ calssName); // InvalidClassException

            Employee emp = (Employee) readObject;
            System.out.format("Obj[No:%s, Name:%s, Pass:%s]", emp.eno, emp.name, emp.password);

            ois.close();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
    }
    public static void objects_WriteRead_External( Emp obj, String serFilename ) throws IOException {

Serializable Example Over Network

Distributing object's state across different address spaces, either in different processes on the same computer, or even in multiple computers connected via a network, but which work together by sharing data and invoking methods.

• Data Marshalling
• Stubs and Skeletons

• implementing Serializable vs Externalizable

Here is complete details (For Windows)

1. Download OpenSSl either 3rd or 4th (with e will work better) based on your system 32bit or 64bit .

2. Extract the downloaded zip inside C directory

3. Open the extracted folder up to bin and copy the path ,it should be some thing like C:\openssl-0.9.8k_X64\bin\openssl (add \openssl at end)

4. (Get the path to the bin folder of Jdk ,if you know how,ignore this ) .

Open android studio ~file~Project Structure(ctrl+alt+shift+s) , select SDK location in left side panel ,copy the JDK location and add /bin to it

So final JDK Location will be like C:\Program Files\Android\Android Studio\jre\bin

we are following this method to get Jdk location because you might use embedded jdk like me

now you have OpenSSl location & JDK location

5. now we need debug keystore location , for that open C~>Users~>YourUserName~>.android there should be a file name debug.keystore ,now copy the path location ,it should be some thing like

C:\Users\Redman\.android\debug.keystore

6. now open command prompt and type command

cd YourJDKLocationFromStep4  

in my case

 cd "C:\Program Files\Android\Android Studio\jre\bin"

7. now construct the following command

keytool -exportcert -alias androiddebugkey -keystore YOURKEYSTORELOCATION | YOUROPENSSLLOCATION sha1 -binary | YOUROPENSSLLOCATION base64

in my case the command will look like

keytool -exportcert -alias androiddebugkey -keystore "C:\Users\Redman\.android\debug.keystore" | "C:\openssl-0.9.8k_X64\bin\openssl" sha1 -binary | "C:\openssl-0.9.8k_X64\bin\openssl" base64

now enter this command in command prompt , if you did ever thing right you will be asked for password (password is android)

Enter keystore password:  android

thats it ,you will be given the Key Hash , just copy it and use it

For Signed KeyHash construct the following Command

keytool -exportcert -alias YOUR_ALIAS_FOR_JKS -keystore YOUR_JKS_LOCATION | YOUROPENSSLLOCATION sha1 -binary | YOUROPENSSLLOCATION base64

enter your keystore password , If you enter wrong password it will give wrong KeyHash

NOTE

If for some reason if it gives error at some path then wrap that path in double quotes .Also Windows power shell was not working well for me, I used git bash (or use command prompt) .

example

keytool -exportcert -alias androiddebugkey -keystore "C:\Users\Redman\.android\debug.keystore" | "C:\openssl-0.9.8k_X64\bin\openssl" sha1 -binary | "C:\openssl-0.9.8k_X64\bin\openssl" base64

set scrolling="no" attribute in your iframe.

first use this:

LayoutInflater inflater = (LayoutInflater) Read_file.this
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

Read file is current activity in which you want your context.

View layout = inflater.inflate(R.layout.your_layout_name,(ViewGroup)findViewById(R.id.layout_name_id));

then you can use this to find any element in layout.

ImageView myImage = (ImageView) layout.findViewById(R.id.my_image);

you can try following

int index = 0;
WebElement baseTable = driver.findElement(By.className("table gradient myPage"));
List<WebElement> tableRows = baseTable.findElements(By.tagName("tr"));
tableRows.get(index).getText();

You can also iterate over tablerows to perform any function you want.

Kind of, use the XmlAttribute instead of XmlElement, but it won't look like what you want. It will look like the following:

<SomeModel SomeStringElementName="testData"> 
</SomeModel> 

The only way I can think of to achieve what you want (natively) would be to have properties pointing to objects named SomeStringElementName and SomeInfoElementName where the class contained a single getter named "value". You could take this one step further and use DataContractSerializer so that the wrapper classes can be private. XmlSerializer won't read private properties.

// TODO: make the class generic so that an int or string can be used.
[Serializable]  
public class SerializationClass
{
    public SerializationClass(string value)
    {
        this.Value = value;
    }

    [XmlAttribute("value")]
    public string Value { get; }
}


[Serializable]                     
public class SomeModel                     
{                     
    [XmlIgnore]                     
    public string SomeString { get; set; }                     

    [XmlIgnore]                      
    public int SomeInfo { get; set; }  

    [XmlElement]
    public SerializationClass SomeStringElementName
    {
        get { return new SerializationClass(this.SomeString); }
    }               
}

background-repeat:no-repeat;
background-position:center center;

Does not vertically center the background image when using a html 4.01 'STRICT' doctype.

Adding:

background-attachment: fixed;

Should fix the problem

(So Alexander is right)

According to the WWDC 713_hd_whats_new_in_ios_notifications. The previous size limit of 256 bytes for a push payload has now been increased to 2 kilobytes for iOS 8.

Source: http://asciiwwdc.com/2014/sessions/713?q=notification#1414.0

I'd like to suggest a related solution, which is to pass the @Value-annotated fields as parameters to the constructor, instead of using the ReflectionTestUtils class.

Instead of this:

public class Foo {

    @Value("${foo}")
    private String foo;
}

and

public class FooTest {

    @InjectMocks
    private Foo foo;

    @Before
    public void setUp() {
        ReflectionTestUtils.setField(Foo.class, "foo", "foo");
    }

    @Test
    public void testFoo() {
        // stuff
    }
}

Do this:

public class Foo {

    private String foo;

    public Foo(@Value("${foo}") String foo) {
        this.foo = foo;
    }
}

and

public class FooTest {

    private Foo foo;

    @Before
    public void setUp() {
        foo = new Foo("foo");
    }

    @Test
    public void testFoo() {
        // stuff
    }
}

Benefits of this approach: 1) we can instantiate the Foo class without a dependency container (it's just a constructor), and 2) we're not coupling our test to our implementation details (reflection ties us to the field name using a string, which could cause a problem if we change the field name).

When you only need to check for equality, you can also simply use the in operator to do a membership test in a sequence of accepted elements:

if message.value[0] in ('/', '\\'):
    do_stuff()

Wrap code in

window.onload = function(){ 
    // your code 
};

To calculate the sum of a column in a DataTable use the DataTable.Compute method.

Example of usage from the linked MSDN article:

DataTable table = dataSet.Tables["YourTableName"];

// Declare an object variable.
object sumObject;
sumObject = table.Compute("Sum(Amount)", string.Empty);

Display the result in your Total Amount Label like so:

lblTotalAmount.Text = sumObject.ToString();

I have a similar web app and am not facing that sort of problem at all. What i do is something like this:

var sources = new Array();

sources[0] = /path/to/file.mp4
sources[1] = /path/to/another/file.ogg
etc..

then when i want to change the sources i have a function that does something like this:

this.loadTrack = function(track){
var mediaSource = document.getElementsByTagName('source')[0];
mediaSource.src = sources[track];

    var player = document.getElementsByTagName('video')[0];
    player.load();

}

I do this so that the user can make their way through a playlist, but you could check for userAgent and then load the appropriate file that way. I tried using multiple source tags like everyone on the internet suggested, but i found it much cleaner, and much more reliable to manipulate the src attribute of a single source tag. The code above was written from memory, so i may have glossed over some of hte details, but the general idea is to dynamically change the src attribute of the source tag using javascript, when appropriate.

At least for me, the signal(SIGSEGV ...) approach mentioned in another answer did not work on Win32 with Visual C++ 2015. What did work for me was to use _set_se_translator() found in eh.h. It works like this:

Step 1) Make sure you enable Yes with SEH Exceptions (/EHa) in Project Properties / C++ / Code Generation / Enable C++ Exceptions, as mentioned in the answer by Volodymyr Frytskyy.

Step 2) Call _set_se_translator(), passing in a function pointer (or lambda) for the new exception translator. It is called a translator because it basically just takes the low-level exception and re-throws it as something easier to catch, such as std::exception:

#include <string>
#include <eh.h>

// Be sure to enable "Yes with SEH Exceptions (/EHa)" in C++ / Code Generation;
_set_se_translator([](unsigned int u, EXCEPTION_POINTERS *pExp) {
    std::string error = "SE Exception: ";
    switch (u) {
    case 0xC0000005:
        error += "Access Violation";
        break;
    default:
        char result[11];
        sprintf_s(result, 11, "0x%08X", u);
        error += result;
    };
    throw std::exception(error.c_str());
});

Step 3) Catch the exception like you normally would:

try{
    MakeAnException();
}
catch(std::exception ex){
    HandleIt();
};

Use npm outdated to see Current and Latest version of all packages.

Then npm i packageName@versionNumber to install specific version : example npm i [email protected].

Or npm i packageName@latest to install latest version : example npm i browser-sync@latest.

Yeah there's no built in classes to do this that I'm aware of.

But that shouldn't really be an issue should it? It looks easy enough to parse just by storing the result of Stream.ReadToEnd() in a string, splitting based on new lines and then splitting each record on the = character. What you'd be left with is a bunch of key value pairs which you can easily toss into a dictionary.

Here's an example that might work for you:

public static Dictionary<string, string> GetProperties(string path)
{
    string fileData = "";
    using (StreamReader sr = new StreamReader(path))
    {
        fileData = sr.ReadToEnd().Replace("\r", "");
    }
    Dictionary<string, string> Properties = new Dictionary<string, string>();
    string[] kvp;
    string[] records = fileData.Split("\n".ToCharArray());
    foreach (string record in records)
    {
        kvp = record.Split("=".ToCharArray());
        Properties.Add(kvp[0], kvp[1]);
    }
    return Properties;
}

Here's an example of how to use it:

Dictionary<string,string> Properties = GetProperties("data.txt");
Console.WriteLine("Hello: " + Properties["Hello"]);
Console.ReadKey();

This is not about the difference between Window.ContentRendered and Window.Loaded but about what how the Window.Loaded event can be used:

I use it to avoid splash screens in all applications which need a long time to come up.

    // initializing my main window
    public MyAppMainWindow()
    {
        InitializeComponent();

        // Set the event
        this.ContentRendered += MyAppMainWindow_ContentRendered;
    }

    private void MyAppMainWindow_ContentRendered(object sender, EventArgs e)
    {
        // ... comes up quick when the controls are loaded and rendered

        // unset the event
        this.ContentRendered -= MyAppMainWindow_ContentRendered;

        // ... make the time comsuming init stuff here
    }

I had a similar problem. I am posting my solution here because I believe it might help one of the commenters.

For me, the obstacle was that the page required a login and then gave me a new URL through javascript. Here is what I had to do:

curl -c cookiejar -g -O -J -L -F "j_username=username" -F "j_password=password" <URL>

Note that j_username and j_password is the name of the fields for my website's login form. You will have to open the source of the webpage to see what the 'name' of the username field and the 'name' of the password field is in your case. After that I go an html file with java script in which the new URL was embedded. After parsing this out just resubmit with the new URL:

curl -c cookiejar -g -O -J -L -F "j_username=username" -F "j_password=password" <NEWURL>

You could split the string on the whitespace and then re-add it, since you know its in between every one of the entries.

var string = "text to split";
    string = string.split(" ");
var stringArray = new Array();
for(var i =0; i < string.length; i++){
    stringArray.push(string[i]);
    if(i != string.length-1){
        stringArray.push(" ");
    }
}

Update: Removed trailing space.

This is the disassembled code from .NET Reflector for Path.Combine method. Check IsPathRooted function. If the second path is rooted (starts with a DirectorySeparatorChar), return second path as it is.

public static string Combine(string path1, string path2)
{
    if ((path1 == null) || (path2 == null))
    {
        throw new ArgumentNullException((path1 == null) ? "path1" : "path2");
    }
    CheckInvalidPathChars(path1);
    CheckInvalidPathChars(path2);
    if (path2.Length == 0)
    {
        return path1;
    }
    if (path1.Length == 0)
    {
        return path2;
    }
    if (IsPathRooted(path2))
    {
        return path2;
    }
    char ch = path1[path1.Length - 1];
    if (((ch != DirectorySeparatorChar) &&
         (ch != AltDirectorySeparatorChar)) &&
         (ch != VolumeSeparatorChar))
    {
        return (path1 + DirectorySeparatorChar + path2);
    }
    return (path1 + path2);
}


public static bool IsPathRooted(string path)
{
    if (path != null)
    {
        CheckInvalidPathChars(path);
        int length = path.Length;
        if (
              (
                  (length >= 1) &&
                  (
                      (path[0] == DirectorySeparatorChar) ||
                      (path[0] == AltDirectorySeparatorChar)
                  )
              )

              ||

              ((length >= 2) &&
              (path[1] == VolumeSeparatorChar))
           )
        {
            return true;
        }
    }
    return false;
}

If you're still wondering how to solve it.

I use

$protected $dates = ['created_at','updated_at','aired'];

In my model and in my where i do

where('aired','>=',time())

So just use the unix to compaire in where.

In views on the otherhand you have to use the date object.

Hope it helps someone!

If you're using some sort of virtual environment do this!

1. Exit from your virtual environment.

2. Activate your virtual environment.

After you've done this you can try running your command again and this time it probably won't have any ImportErrors.

If you are working with redis and Java 8, you can take a look at JetCache:

@Cached(expire = 10, timeUnit = TimeUnit.MINUTES) User getUserById(long userId);

I was struggling with this for some time and after some help on a post I was able to come up with this formula =(DATEVALUE(LEFT(XX,10)))+(TIMEVALUE(MID(XX,12,5))) where XX is the cell in reference.

I've come across many other forums with people asking the same thing and this, to me, seems to be the simplest answer. What this will do is return text that is copied in from this format 2014/11/20 11:53 EST and turn it in to a Date/Time format so it can be sorted oldest to newest. It works with short date/long date and if you want the time just format the cell to display time and it will show. Hope this helps anyone who goes searching around like I did.

As far as i know it wouldn't be possible to change the spark.executor.memory at run time. If you are running a stand-alone version, with pyspark and graphframes, you can launch the pyspark REPL by executing the following command:

pyspark --driver-memory 2g --executor-memory 6g --packages graphframes:graphframes:0.7.0-spark2.4-s_2.11

Be sure to change the SPARK_VERSION environment variable appropriately regarding the latest released version of Spark

That's strange, it definitely works for me:

from matplotlib import pyplot as plt

plt.figure(figsize = (20,2))
plt.imshow(random.rand(8, 90), interpolation='nearest')

I am using the "MacOSX" backend, btw.

I had a similar problem and I just modified the event handler to check the type of the variable. The type is only set after the user selects a value, not when the page is first loaded.

self.permissionChanged = function (l) {
    if (typeof l != 'undefined') {
        ...
    }
}

This seems to work for me.

On the "How to do it" part:

I think the introduction to ScalaTest does good job of illustrating different styles of unit tests.

On the "When to do it" part:

Unit testing is not only for testing. By doing unit testing you also force the design of the software into something that is unit testable. Many people are of the opinion that this design is for the most part Good Design(TM) regardless of other benefits from testing.

So one reason to do unit test is to force your design into something that hopefully will be easier to maintain that what it would be had you not designed it for unit testing.

Interestingly, this solution can break, but a workaround: Looking for my database called KeyWorks.accdb which must exist:

Run this:

Dim strDataPath As String = GetSetting("KeyWorks", "dataPath", "01", "") 'get from registry

If Not strDataPath.Contains("KeyWorks.accdb") Then....etc.

If my database is named KeyWorksBB.accdb, the If statement will find this acceptable and exit the If statement because it did indeed find KeyWorks and accdb.

If I surround the If statement qualifier with single quotes like 'KeyWorks.accdb', it now looks for all the consecutive characters in order and would enter the If block because it did not match.

One possible solution is using nine patch image like this http://developer.android.com/guide/topics/graphics/2d-graphics.html#nine-patch

You can set the format in aspx, just add the property "DateFormatString" in your BoundField.

DataFormatString="{0:dd/MM/yyyy hh:mm:ss}"

delete_all is a single SQL DELETE statement and nothing more. destroy_all calls destroy() on all matching results of :conditions (if you have one) which could be at least NUM_OF_RESULTS SQL statements.

If you have to do something drastic such as destroy_all() on large dataset, I would probably not do it from the app and handle it manually with care. If the dataset is small enough, you wouldn't hurt as much.

I found an easier way to go about this nagging problem. Register GlassFish Server without setting user/password the first time. Then right click GlassFish then to View Domain Admin Console. On the Glassfish admin page that appears, you will see Change Administrator Password under Administration on the GlassFish Console- Common Tasks. Click to set your password by changing the default password. The user is admin but the password is up to you to change it. Save your change. Go back to Netbeans and you will immediately see a popout screen asking you to enter your admin credentials. Enter admin for user and the password. That is it. If your Netbeans come with Glassfish, just right click the server then to View Domain Admin Console then follow the rest of the steps explained above

Another 2 very usefull shortcuts are to move lines selected up and down, like sublime text does...

{
  "key" : "ctrl+shift+down", "command" : "editor.action.moveLinesDownAction",
  "when" : "editorTextFocus && !editorReadonly"
},

and

{
  "key" : "ctrl+shift+up", "command" : "editor.action.moveLinesUpAction",
  "when" : "editorTextFocus && !editorReadonly"
}

Change it to the following:

$ci->email->initialize($config);

$ci->email->from('[email protected]', 'Blabla');
$list = array('[email protected]');
$ci->email->to($list);

For your question as asked

Columns(3).Insert
Range("c1:c4") = Application.Transpose(Array("Loc", "uk", "us", "nj"))

If you had a way of automatically looking up the data (ie matching uk against employer id) then you could do that in VBA

You cannot make POST HTTP Requests by <a href="some_script.php">some_script</a>

Just open your house.php, find in it where you have $house = $_POST['houseVar'] and change it to:

isset($_POST['houseVar']) ? $house = $_POST['houseVar'] : $house = $_GET['houseVar']

And in the streeview.php make links like that:

<a href="house.php?houseVar=$houseNum"></a>

Or something else. I just don't know your files and what inside it.

@Giuseppe, you may want to consider this for a flexible specification of the plots arrangement (modified from here):

library(ggplot2)
library(gridExtra)
library(grid)

grid_arrange_shared_legend <- function(..., nrow = 1, ncol = length(list(...)), position = c("bottom", "right")) {

  plots <- list(...)
  position <- match.arg(position)
  g <- ggplotGrob(plots[[1]] + theme(legend.position = position))$grobs
  legend <- g[[which(sapply(g, function(x) x$name) == "guide-box")]]
  lheight <- sum(legend$height)
  lwidth <- sum(legend$width)
  gl <- lapply(plots, function(x) x + theme(legend.position = "none"))
  gl <- c(gl, nrow = nrow, ncol = ncol)

  combined <- switch(position,
                     "bottom" = arrangeGrob(do.call(arrangeGrob, gl),
                                            legend,
                                            ncol = 1,
                                            heights = unit.c(unit(1, "npc") - lheight, lheight)),
                     "right" = arrangeGrob(do.call(arrangeGrob, gl),
                                           legend,
                                           ncol = 2,
                                           widths = unit.c(unit(1, "npc") - lwidth, lwidth)))
  grid.newpage()
  grid.draw(combined)

}

Extra arguments nrow and ncol control the layout of the arranged plots:

dsamp <- diamonds[sample(nrow(diamonds), 1000), ]
p1 <- qplot(carat, price, data = dsamp, colour = clarity)
p2 <- qplot(cut, price, data = dsamp, colour = clarity)
p3 <- qplot(color, price, data = dsamp, colour = clarity)
p4 <- qplot(depth, price, data = dsamp, colour = clarity)
grid_arrange_shared_legend(p1, p2, p3, p4, nrow = 1, ncol = 4)
grid_arrange_shared_legend(p1, p2, p3, p4, nrow = 2, ncol = 2)

We had the same issue and, in our case, it was resolved by reinstalling the certificate and creating the binding again. What lead us there was the fact that even getting a simple png image file on the site give the same error.

If you just run jmap -histo:live or jmap -histo, it outputs the contents on the console!

I guess that you need a formatted output.

System.out.printf("%.2f",d);

Below Command where project is a folder which contains package.json file

npm run --prefix project ${COMMAND}

is working as well. Useful in Docker based applications.

Take a look at your code :

 getUsers(): Observable<User[]> {
        return Observable.create(observer => {
            this.http.get('http://users.org').map(response => response.json();
        })
    }

and code from https://angular.io/docs/ts/latest/tutorial/toh-pt6.html (BTW. really good tutorial, you should check it out)

 getHeroes(): Promise<Hero[]> {
    return this.http.get(this.heroesUrl)
               .toPromise()
               .then(response => response.json().data as Hero[])
               .catch(this.handleError);
  }

The HttpService inside Angular2 already returns an observable, sou don't need to wrap another Observable around like you did here:

   return Observable.create(observer => {
        this.http.get('http://users.org').map(response => response.json()

Try to follow the guide in link that I provided. You should be just fine when you study it carefully.

---EDIT----

First of all WHERE you log the this.users variable? JavaScript isn't working that way. Your variable is undefined and it's fine, becuase of the code execution order!

Try to do it like this:

  getUsers(): void {
        this.userService.getUsers()
            .then(users => {
               this.users = users
               console.log('this.users=' + this.users);
            });


    }

See where the console.log(...) is!

Try to resign from toPromise() it's seems to be just for ppl with no RxJs background.

Catch another link: https://scotch.io/tutorials/angular-2-http-requests-with-observables Build your service once again with RxJs observables.

Use Projections to specify which columns you would like to return.

Example

SQL Query

SELECT user.id, user.name FROM user;

Hibernate Alternative

Criteria cr = session.createCriteria(User.class)
    .setProjection(Projections.projectionList()
      .add(Projections.property("id"), "id")
      .add(Projections.property("Name"), "Name"))
    .setResultTransformer(Transformers.aliasToBean(User.class));

  List<User> list = cr.list();

If you have to do a curl in php, you should use urlencode() from PHP but individually!

strPOST = "Item1=" . $Value1 . "&Item2=" . urlencode("+")

If you do urlencode(strPOST), you will bring you another problem, you will have one Item1 and & will be change %xx value and be as one value, see down here the return!

Example 1

$strPOST = "Item1=" . $Value1 . "&Item2=" . urlencode("+") will give Item1=Value1&Item2=%2B

Example 2

$strPOST = urlencode("Item1=" . $Value1 . "&Item2=+") will give Item1%3DValue1%26Item2%3D%2B

Example 1 is the good way to prepare string for POST in curl

Example 2 show that the receptor will not see the equal and the ampersand to distinguish both value!

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

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

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

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

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

EDIT:

The OP was not looking to use cross-domain requests, but jQuery supports JSONP as of v1.5. See jQuery.ajax(), specificically the crossDomain parameter.

The regular jQuery Ajax requests will not work cross-site, so if you want to query a remote RESTful web service, you'll probably have to make a proxy on your server and query that with a jQuery get request. See this site for an example.

If it's a SOAP web service, you may want to try the jqSOAPClient plugin.

As you are looking for form object changes, the best watching approach is to use
$watchCollection. Please have a look into official documentation for different performance characteristics.

This is one of the best suggestion in which is done using query. Good for those who has a lot of databases just like me. Can run it using a script.

https://medium.com/@bharatdwarkani/shrinking-sql-server-db-log-file-size-sql-server-db-maintenance-7ddb0c331668

USE DatabaseName;
GO

I discovered that the order of adding roles and features is important. On a fresh system I activate the role "application server" and there check explicitly .net, web server support and finally process activation service Then automatically a dialogue comes up that the role "Web server" needs to be added also.

You can use the /s switch for del to delete in subfolders as well.

Example

del D:\test\*.* /s

Would delete all files under test including all files in all subfolders.

To remove folders use rd, same switch applies.

rd D:\test\folder /s /q

rd doesn't support wildcards * though so if you want to recursively delete all subfolders under the test directory you can use a for loop.

for /r /d D:\test %a in (*) do rd %a /s /q

If you are using the for option in a batch file remember to use 2 %'s instead of 1.

The .map files are for js and css (and now ts too) files that have been minified. They are called SourceMaps. When you minify a file, like the angular.js file, it takes thousands of lines of pretty code and turns it into only a few lines of ugly code. Hopefully, when you are shipping your code to production, you are using the minified code instead of the full, unminified version. When your app is in production, and has an error, the sourcemap will help take your ugly file, and will allow you to see the original version of the code. If you didn't have the sourcemap, then any error would seem cryptic at best.

Same for CSS files. Once you take a SASS or LESS file and compile it to CSS, it looks nothing like its original form. If you enable sourcemaps, then you can see the original state of the file, instead of the modified state.

So, to answer you questions in order:

• What is it for? To de-reference uglified code
• How can a developer use it? You use it for debugging a production app. In development mode you can use the full version of Angular. In production, you would use the minified version.
• Should I care about creating a js.map file? If you care about being able to debug production code easier, then yes, you should do it.
• How does it get created? It is created at build time. There are build tools that can build your .map file for you as it does other files. https://github.com/gruntjs/grunt-contrib-uglify/issues/71

I hope this makes sense.

With the information provided, I'd model the database to have the following:

POLICIES

• POLICY_ID (primary key)

LIABILITIES

• LIABILITY_ID (primary key)
• POLICY_ID (foreign key)

PROPERTIES

• PROPERTY_ID (primary key)
• POLICY_ID (foreign key)

...and so on, because I'd expect there to be different attributes associated with each section of the policy. Otherwise, there could be a single SECTIONS table and in addition to the policy_id, there'd be a section_type_code...

Either way, this would allow you to support optional sections per policy...

I don't understand what you find unsatisfactory about this approach - this is how you store data while maintaining referential integrity and not duplicating data. The term is "normalized"...

Because SQL is SET based, it's rather alien to procedural/OO programming concepts & requires code to transition from one realm to the other. ORMs are often considered, but they don't work well in high volume, complex systems.

Your pizza can have exactly three topping types:

• one type of cheese
• one type of meat
• one type of vegetable

So we order two pizzas and choose the following toppings:

Pizza    Topping     Topping Type
-------- ----------  -------------
1        mozzarella  cheese
1        pepperoni   meat
1        olives      vegetable
2        mozzarella  meat
2        sausage     cheese
2        peppers     vegetable

Wait a second, mozzarella can't be both a cheese and a meat! And sausage isn't a cheese!

We need to prevent these sorts of mistakes, to make mozzarella always be cheese. We should use a separate table for this, so we write down that fact in only one place.

Pizza    Topping
-------- ----------
1        mozzarella
1        pepperoni
1        olives
2        mozzarella 
2        sausage
2        peppers

Topping     Topping Type
----------  -------------
mozzarella  cheese
pepperoni   meat
olives      vegetable
sausage     meat
peppers     vegetable

That was the explanation that an 8 year-old might understand. Here is the more technical version.

BCNF acts differently from 3NF only when there are multiple overlapping candidate keys.

The reason is that the functional dependency X -> Y is of course true if Y is a subset of X. So in any table that has only one candidate key and is in 3NF, it is already in BCNF because there is no column (either key or non-key) that is functionally dependent on anything besides that key.

Because each pizza must have exactly one of each topping type, we know that (Pizza, Topping Type) is a candidate key. We also know intuitively that a given topping cannot belong to different types simultaneously. So (Pizza, Topping) must be unique and therefore is also a candidate key. So we have two overlapping candidate keys.

I showed an anomaly where we marked mozarella as the wrong topping type. We know this is wrong, but the rule that makes it wrong is a dependency Topping -> Topping Type which is not a valid dependency for BCNF for this table. It's a dependency on something other than a whole candidate key.

So to solve this, we take Topping Type out of the Pizzas table and make it a non-key attribute in a Toppings table.

i think in the svn browser in tortoisesvn you can just drag it from one place to another.

Using underscore unique lib following is working for me, I m making list unique on the based of _id then returning String value of _id:

var uniqueEntities = _.uniq(entities, function (item, key, a) {
                                    return item._id.toString();
                                });

I did encounter the same problem while trying to read data from a Firebird Database. After many hours of searching, I found out that the problem was caused by an error I made in the query. Fixing it made it work perfectly. It had nothing to do with the version of the Framework

There are at least two ways for achieving this in base graph (my examples are for the x-axis, but work the same for the y-axis):

1. Use par(xaxp = c(x1, x2, n)) or plot(..., xaxp = c(x1, x2, n)) to define the position (x1 & x2) of the extreme tick marks and the number of intervals between the tick marks (n). Accordingly, n+1 is the number of tick marks drawn. (This works only if you use no logarithmic scale, for the behavior with logarithmic scales see ?par.)

2. You can suppress the drawing of the axis altogether and add the tick marks later with axis().
   To suppress the drawing of the axis use plot(... , xaxt = "n").
   Then call axis() with side, at, and labels: axis(side = 1, at = v1, labels = v2). With side referring to the side of the axis (1 = x-axis, 2 = y-axis), v1 being a vector containing the position of the ticks (e.g., c(1, 3, 5) if your axis ranges from 0 to 6 and you want three marks), and v2 a vector containing the labels for the specified tick marks (must be of same length as v1, e.g., c("group a", "group b", "group c")). See ?axis and my updated answer to a post on stats.stackexchange for an example of this method.

I found an answer now. Thanks for your suggestions!

for e in ./*.cutoff.txt; do
if grep -q -E 'COX1|Cu-oxidase' $e
then
    echo xyz >$e.match.txt
else
    echo
fi

if grep -q -E 'AMO' $e
then
    echo abc >$e.match.txt
else
    echo
fi; done

Any comments on that? It seems inefficient to grep twice, but it works...

Try this one:

Sub clear_sht
  Dim sht As Worksheet
  Set sht = Worksheets(GENERATOR_SHT_NAME)
  col_cnt = sht.UsedRange.Columns.count
  If col_cnt = 0 Then
    col_cnt = 1
  End If

  sht.Range(sht.Cells(1, 1), sht.Cells(sht.UsedRange.Rows.count, col_cnt)).Clear
End Sub

Can we see the structure of your table? If I am understanding this, then the assumption made by the query is that a record can be only meta_key - 'lat' or meta_key = 'long' not both because each row only has one meta_key column and can only contain 1 corresponding value, not 2. That would explain why you don't get results when you connect the with an AND; it's impossible.

FYI: I also noticed I can mess up a perfectly working spring boot app and prevent it from serving contents from the static folder, if I add a bad rest controller like so

 @RestController
public class BadController {
    @RequestMapping(method= RequestMethod.POST)
    public String someMethod(@RequestParam(value="date", required=false)String dateString, Model model){
        return "foo";
    }
}

In this example, after adding the bad controller to the project, when the browser asks for a file available in static folder, the error response is '405 Method Not Allowed'.

Notice paths are not mapped in the bad controller example.

Here is a simple solution

try adding this dependency

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.8.3</version>
</dependency>

Here is a good discussion about superclass constructor calling rules. You always want the base class constructor to be called before the derived class constructor in order to form an object properly. Which is why this form is used

  B( int v) : A( v )
  {
  }

Use the apache commons cli if you plan on extending that past a single arg.

"The Apache Commons CLI library provides an API for parsing command line options passed to programs. It's also able to print help messages detailing the options available for a command line tool."

Commons CLI supports different types of options:

• POSIX like options (ie. tar -zxvf foo.tar.gz)
• GNU like long options (ie. du --human-readable --max-depth=1)
• Java like properties (ie. java -Djava.awt.headless=true -Djava.net.useSystemProxies=true Foo)
• Short options with value attached (ie. gcc -O2 foo.c)
• long options with single hyphen (ie. ant -projecthelp)

It won't be fast, and there will be a lot for you to type (unless you generate the SQL from user_tab_columns), but here is what I use when I need to compare two tables row-by-row and column-by-column.

The query will return all rows that

• Exists in table1 but not in table2
• Exists in table2 but not in table1
• Exists in both tables, but have at least one column with a different value

(common identical rows will be excluded).

"PK" is the column(s) that make up your primary key. "a" will contain A if the present row exists in table1. "b" will contain B if the present row exists in table2.

select pk
      ,decode(a.rowid, null, null, 'A') as a
      ,decode(b.rowid, null, null, 'B') as b
      ,a.col1, b.col1
      ,a.col2, b.col2
      ,a.col3, b.col3
      ,...
  from table1 a 
  full outer 
  join table2 b using(pk)
 where decode(a.col1, b.col1, 1, 0) = 0
    or decode(a.col2, b.col2, 1, 0) = 0
    or decode(a.col3, b.col3, 1, 0) = 0
    or ...;

Edit Added example code to show the difference described in comment. Whenever one of the values contains NULL, the result will be different.

with a as(
   select 0    as col1 from dual union all
   select 1    as col1 from dual union all
   select null as col1 from dual
)
,b as(
   select 1    as col1 from dual union all
   select 2    as col1 from dual union all
   select null as col1 from dual
)   
select a.col1
      ,b.col1
      ,decode(a.col1, b.col1, 'Same', 'Different') as approach_1
      ,case when a.col1 <> b.col1 then 'Different' else 'Same' end as approach_2       
  from a,b
 order 
    by a.col1
      ,b.col1;    




col1   col1_1   approach_1  approach_2
====   ======   ==========  ==========
  0        1    Different   Different  
  0        2    Different   Different  
  0      null   Different   Same         <--- 
  1        1    Same        Same       
  1        2    Different   Different  
  1      null   Different   Same         <---
null       1    Different   Same         <---
null       2    Different   Same         <---
null     null   Same        Same       

This is not necessarily a VBA task - This specific task is easiest sollowed with Auto filter.

1.Insert Auto filter (In Excel 2010 click on home-> (Editing) Sort & Filter -> Filter)
2. Filter on the 'Websites' column
3. Mark the 'none' and delete them
4. Clear filter

a=[100,200,300,400,500]
def search(b):
 try:
  k=a.index(b)
  return a[k] 
 except ValueError:
    return 'not found'
print(search(500))

it'll return the object if found else it'll return "not found"

I think an option for your purposes is git log --online --decorate. This lets you know the checked commit, and the top commits for each branch that you have in your story line. By doing this, you have a nice view on the structure of your repo and the commits associated to a specific branch. I think reading this might help.

Here are some other solutions. No need to use additional plugins.

Snippets down below uses .subtract API and requires moment 2.1.0+

Snippets are also available in here https://jsfiddle.net/traBolic/ku5cyrev/

Formatting with the .format API:

const duration = moment.duration(9, 's');

const intervalId = setInterval(() => {
  duration.subtract(1, "s");

  const inMilliseconds = duration.asMilliseconds();

  // "mm:ss:SS" will include milliseconds
  console.log(moment.utc(inMilliseconds).format("HH[h]:mm[m]:ss[s]"));

  if (inMilliseconds !== 0) return;

  clearInterval(intervalId);
  console.warn("Times up!");
}, 1000);

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.27.0/moment.min.js"></script>

Manuel formatting by .hours, .minutes and .seconds API in a template string

const duration = moment.duration(9, 's');

const intervalId = setInterval(() => {
  duration.subtract(1, "s");

  console.log(`${duration.hours()}h:${duration.minutes()}m:${duration.seconds()}s`);
  // `:${duration.milliseconds()}` to add milliseconds

  if (duration.asMilliseconds() !== 0) return;

If you are insisting to use the window.location.origin You can put this in top of your code before reading the origin

if (!window.location.origin) {
  window.location.origin = window.location.protocol + "//" + window.location.hostname + (window.location.port ? ':' + window.location.port: '');
}

Solution

PS: For the record, it was actually the original question. It was already edited :)

For a group of inputs you can use an improved version based in @mikemaccana's answer

$.fn.isValid = function(){
    var validate = true;
    this.each(function(){
        if(this.checkValidity()==false){
            validate = false;
        }
    });
};

now you can use this to verify if the form is valid:

if(!$(".form-control").isValid){
    return;
}

You could use the same technique to get all the error messages:

$.fn.getVelidationMessage = function(){
    var message = "";
    var name = "";
    this.each(function(){
        if(this.checkValidity()==false){
            name = ($( "label[for=" + this.id + "] ").html() || this.placeholder || this.name || this.id);
            message = message + name +":"+ (this.validationMessage || 'Invalid value.')+"\n<br>";
        }
    })
    return message;
}

Another way of doing this is using a Map (HashMap) with Key, Value pairs representing your object.

Map<Long, Object> map = new HashMap<Long, Object>();
map.put(new Long(1), "one");
map.put(new Long(2), "two");

In JSTL

<c:if test="${not empty map[1]}">

This should return true if the pair exist in the map

It's very simple steps to push your node js application from local to GitHub.

Steps:

1. First create a new repository on GitHub
2. Open Git CMD installed to your system (Install GitHub Desktop)
3. Clone the repository to your system with the command: git clone repo-url
4. Now copy all your application files to this cloned library if it's not there
5. Get everything ready to commit: git add -A
6. Commit the tracked changes and prepares them to be pushed to a remote repository: git commit -a -m "First Commit"
7. Push the changes in your local repository to GitHub: git push origin master

For me, using Anaconda Prompt instead of cmd or PowerShell is the key.

There is a whole page in the MATLAB documentation dedicated to this topic: Array vs. Matrix Operations. The gist of it is below:

MATLAB® has two different types of arithmetic operations: array operations and matrix operations. You can use these arithmetic operations to perform numeric computations, for example, adding two numbers, raising the elements of an array to a given power, or multiplying two matrices.

Matrix operations follow the rules of linear algebra. By contrast, array operations execute element by element operations and support multidimensional arrays. The period character (.) distinguishes the array operations from the matrix operations. However, since the matrix and array operations are the same for addition and subtraction, the character pairs .+ and .- are unnecessary.

If you're creating multiple maps in a loop, if a single map DOM element doesn't exist, it breaks all of them. First, check to make sure the DOM element exists before creating a new Map object.

[...]

for( var i = 0; i <= self.multiple_maps; i++ ) {

  var map_element = document.getElementById( 'map' + '-' + i.toString() );

If it's just for display purposes, you can render the text as upper or lower case in pure CSS, without any Javascript using the text-transform property:

.myclass {
    text-transform: lowercase;
}

See https://developer.mozilla.org/en/CSS/text-transform for more info.

However, note that this doesn't actually change the value to lower case; it just displays it that way. This means that if you examine the contents of the element (ie using Javascript), it will still be in its original format.

I finally invoked in sync mode by including the .Result

OR condition in #ifdef

#if defined LINUX || defined ANDROID
// your code here
#endif /* LINUX || ANDROID */

or-

#if defined(LINUX) || defined(ANDROID)
// your code here
#endif /* LINUX || ANDROID */

Both above are the same, which one you use simply depends on your taste.

P.S.: #ifdef is simply the short form of #if defined, however, does not support complex condition.

Further-

• AND: #if defined LINUX && defined ANDROID
• XOR: #if defined LINUX ^ defined ANDROID

Facebook's new "Page Plugin" width ranges from 180px to 500px as per the documentation.

• If configured below 180px it would enforce a minimum width of 180px
• If configured above 500px it would enforce a maximum width of 500px

With Adaptive Width checked, ex:

Unlike like-box, this plugin enforces its limits by sticking to the boundary values if mis-configured.

For small screens / Responsive behaviors

• When rendering on smaller screens, enforce desiered width on the plugin container and plugin would try to fit in.

• The plugin renders at a smaller width (to fit in smaller screens) automatically, if the container is of slimmer than the configured width.

• You can scale down the container on mobile and the plugin will fit in as long as it gets the minimum of 180px to fit in.

Without Adaptive Width

• The plugin will render at the width specified, irrespective of the container width

The empty string is false as a rule.

Apparently the empty string is not respected as empty in all browsers and the presence of the checked attribute is taken to mean checked. So the entire attribute must either be present or omitted.

First you define a thread. And if you never call join() or detach() before calling the thread destructor, the program will abort.

As follows, calling a thread destructor without first calling join (to wait for it to finish) or detach is guarenteed to immediately call std::terminate and end the program.

Either implicitly detaching or joining a joinable() thread in its destructor could result in difficult to debug correctness (for detach) or performance (for join) bugs encountered only when an exception is raised. Thus the programmer must ensure that the destructor is never executed while the thread is still joinable.

The HTML tags that you want to edit is called the DOM (Document object manipulate), you can edit the DOM with many functions in the document global object.

The best example that would work on almost any browser is the document.getElementById, it's search for html tag with that id set as an attribute.

There is another option which is easier but works only on modern browsers (IE8+), the querySelector function, it's will find the first element with the matched selector (CSS selectors).

Examples for both options:

<script>_x000D_
var name = prompt("What's your name?");_x000D_
var lengthOfName = name.length_x000D_
</script>_x000D_
<body>_x000D_
  <p id="a"></p>_x000D_
  <p id="b"></p>_x000D_
  <script>_x000D_
    document.getElementById('a').innerHTML = name;_x000D_
document.querySelector('#b').innerHTML = name.length;</script>_x000D_
</body>

If you are grouping by some other value, then instead of what you have,

write it as

Sum(CASE WHEN col1 > col2 THEN SUM(col3*col4) ELSE 0 END) as SumSomeProduct

If, otoh, you want to group By the internal expression, (col3*col4) then

write the group By to match the expression w/o the SUM...

Select Sum(Case When col1 > col2 Then col3*col4 Else 0 End) as SumSomeProduct
From ...

Group By Case When col1 > col2 Then col3*col4 Else 0 End 

Finally, if you want to group By the actual aggregate

Select SumSomeProduct, Count(*), <other aggregate functions>
From (Select <other columns you are grouping By>, 
      Sum(Case When col1 > col2 
          Then col3*col4 Else 0 End) as SumSomeProduct
      From Table
      Group By <Other Columns> ) As Z
Group by SumSomeProduct

I'm on Windows 7 64 bit and couldn't understand if I can manually enable JRE8 64 bit for Chrome. Turned out that my problem was that Java plugin DLL is 64 bit which wouldn't work in 32 bit Chrome.

There is a way to increase character using ascii_letters from string package which ascii_letters is a string that contains all English alphabet, uppercase and lowercase:

>>> from string import ascii_letters
>>> ascii_letters[ascii_letters.index('a') + 1]
'b'
>>> ascii_letters
'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'

Also it can be done manually;

>>> letters = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'
>>> letters[letters.index('c') + 1]
'd'

ansible your_server_name -i custom_inventory_file_name -m -a "uptime"

The default module is command module, hence command keyword is not required.

If you need to issue any command with elevated privileges use -b at the end of the same command.

ansible your_server_name -i custom_inventory_file_name -m -a "uptime" -b

There is another way if all you want is the text up to the first line feed:

x='some
thing'

y=${x%$'\n'*}

After that y will contain some and nothing else (no line feed).

What is happening here?

We perform a parameter expansion substring removal (${PARAMETER%PATTERN}) for the shortest match up to the first ANSI C line feed ($'\n') and drop everything that follows (*).

After some trials, knowing that I had all the factors stated in this thread and other threads properly configured, I still got this error in Android Studio.

Even after installing externally, it seems Android Studio could not discover that HAXM is already installed, unless it gets to install it itself.

As a solution that worked for me, under User\AppData\Local\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager which android has downloaded when attempting to install HAXM, click the installer and uninstall the software, then re-try from Android Studio to install it, it should work now.

When you use varargs, it can result in the creation of an Object[] to hold the arguments.

Due to escape analysis, the JIT can optimise away this array creation. (One of the few times I have found it does so) Its not guaranteed to be optimised away, but I wouldn't worry about it unless you see its an issue in your memory profiler.

AFAIK @SafeVarargs suppresses a warning by the compiler and doesn't change how the JIT behaves.

zeusstl is right. it works for me too.

   <select class="form-control select2" id="myselect">
                      <option disabled="disabled" selected></option>
                      <option>Male</option>
                      <option>Female</option>
                    </select>

   $.getJSON("mysite/json1.php", function(json){
        $('#myselect').empty();
        $('#myselect').append($('<option>').text("Select"));
        $.each(json, function(i, obj){

  $('#myselect').append($('<option>').text(obj.text).attr('value', obj.val));
        });
  });

Java version of barycentric method:

class Triangle {
    Triangle(double x1, double y1, double x2, double y2, double x3,
            double y3) {
        this.x3 = x3;
        this.y3 = y3;
        y23 = y2 - y3;
        x32 = x3 - x2;
        y31 = y3 - y1;
        x13 = x1 - x3;
        det = y23 * x13 - x32 * y31;
        minD = Math.min(det, 0);
        maxD = Math.max(det, 0);
    }

    boolean contains(double x, double y) {
        double dx = x - x3;
        double dy = y - y3;
        double a = y23 * dx + x32 * dy;
        if (a < minD || a > maxD)
            return false;
        double b = y31 * dx + x13 * dy;
        if (b < minD || b > maxD)
            return false;
        double c = det - a - b;
        if (c < minD || c > maxD)
            return false;
        return true;
    }

    private final double x3, y3;
    private final double y23, x32, y31, x13;
    private final double det, minD, maxD;
}

The above code will work accurately with integers, assuming no overflows. It will also work with clockwise and anticlockwise triangles. It will not work with collinear triangles (but you can check for that by testing det==0).

The barycentric version is fastest if you are going to test different points with the same triangle.

The barycentric version is not symmetric in the 3 triangle points, so it is likely to be less consistent than Kornel Kisielewicz's edge half-plane version, because of floating point rounding errors.

Credit: I made the above code from Wikipedia's article on barycentric coordinates.

Which version of .NET are you using? Since .NET 3.5, there's an assembly System.Data.DataSetExtensions, which contains various useful extensions for dataTables, dataRows and the like.

You can try using

row.Field<type>("fieldName");

if that doesn't work, you can do this:

DataTable table = new DataTable();
var myColumn = table.Columns.Cast<DataColumn>().SingleOrDefault(col => col.ColumnName == "myColumnName");
if (myColumn != null)
{
    // just some roww
    var tableRow = table.AsEnumerable().First();
    var myData = tableRow.Field<string>(myColumn);
    // or if above does not work
    myData = tableRow.Field<string>(table.Columns.IndexOf(myColumn));
}

Iterable is a generic interface. A problem you might be having (you haven't actually said what problem you're having, if any) is that if you use a generic interface/class without specifying the type argument(s) you can erase the types of unrelated generic types within the class. An example of this is in Non-generic reference to generic class results in non-generic return types.

So I would at least change it to:

public class ProfileCollection implements Iterable<Profile> { 
    private ArrayList<Profile> m_Profiles;

    public Iterator<Profile> iterator() {        
        Iterator<Profile> iprof = m_Profiles.iterator();
        return iprof; 
    }

    ...

    public Profile GetActiveProfile() {
        return (Profile)m_Profiles.get(m_ActiveProfile);
    }
}

and this should work:

for (Profile profile : m_PC) {
    // do stuff
}

Without the type argument on Iterable, the iterator may be reduced to being type Object so only this will work:

for (Object profile : m_PC) {
    // do stuff
}

This is a pretty obscure corner case of Java generics.

If not, please provide some more info about what's going on.

If your shell is bash (amongst others), a shortcut for $(cat afile) is $(< afile), so you'd write:

mycommand "$(< file.txt)"

Documented in the bash man page in the 'Command Substitution' section.

Alterately, have your command read from stdin, so: mycommand < file.txt

I have a simple solution for this problem. You can first type ":retab" and then ":retab!", then everything would be fine

It seems that one of the most common reasons this happens is if you install a new version of PostgreSQL without stopping the service of an existing installation. This was a particular headache of mine, too. Before installing or upgrading, particularly on OS X and using the one click installer from Enterprise DB, make sure you check the status of the old installation before proceeding.

A java.util.Date is not a java.sql.Date. It's the other way around. A java.sql.Date is a java.util.Date.

You'll need to convert it to a java.sql.Date by using the constructor that takes a long that a java.util.Date can supply.

java.sql.Date sqlDate = new java.sql.Date(utilDate.getTime());

Very simply:

Arrays.asList("Hi!")

The answer to the question is $("[id$='txtTitle']"), as Mark Hurd answered, but for those who, like me, want to find all the elements with an id which starts with a given string (for example txtTitle), try this (doc) :

$("[id^='txtTitle']")

If you want to select elements which id contains a given string (doc) :

$("[id*='txtTitle']")

If you want to select elements which id is not a given string (doc) :

$("[id!='myValue']")

(it also matches the elements that don't have the specified attribute)

If you want to select elements which id contains a given word, delimited by spaces (doc) :

$("[id~='myValue']")

If you want to select elements which id is equal to a given string or starting with that string followed by a hyphen (doc) :

$("[id|='myValue']")

For others who may come by here, maybe take a look at : http://openhardwaremonitor.org/

Follow that link and at first you might think, "hey that's an Application, that is why it was removed, the question was how to do this from C# code, not to find an application that can tell me the temperature..." This is where it shows you are not willing to invest enough time in reading what "Open Hardware Monitor" also is.

They also include a Data Interface, here is the description:

Data Interface The Open Hardware Monitor publishes all sensor data to WMI (Windows Management Instrumentation). This allows other applications to read and use the sensor information as well. A preliminary documentation of the interface can be found here(click).

When you download it, it contains the OpenHardwareMonitor.exe application, you're not looking for that one. It also contains the OpenHardwareMonitorLib.dll, you're looking for that one.

It is mostly, if not 100%, just a wrapper around the WinRing0 API, which you could choose to wrap your self if you feel like it.

I have tried this out from a C# app myself, and it works. Although it is still in beta, it seemed rather stable. It is also open source so it could be a good starting point instead.

At the end of the day I find it hard to believe that is not on topic of this question.

The easiest method would be to wrap them both in a container div and apply margin: 0 auto; to the container. This will center both the #page-wrap and the #sidebar divs on the page. However, if you want that off-center look, you could then shift the container 200px to the left, to account for the width of the #sidebar div.

1 and 2 are SAML 1.1 because those URIs were part of the OASIS SAML 1.1 standard. Section 8.3 of the linked PDF for the OASIS SAML 2.0 standard explains this:

Where possible an existing URN is used to specify a protocol. In the case of IETF protocols, the URN of the most current RFC that specifies the protocol is used. URI references created specifically for SAML have one of the following stems, according to the specification set version in which they were first introduced:

urn:oasis:names:tc:SAML:1.0:
urn:oasis:names:tc:SAML:1.1:
urn:oasis:names:tc:SAML:2.0:

Give a try to this

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
    // TODO Auto-generated method stub

    FragmentManager manager = ((Fragment) object).getFragmentManager();
    FragmentTransaction trans = manager.beginTransaction();
    trans.remove((Fragment) object);
    trans.commit();

    super.destroyItem(container, position, object);
}

I use this shell script on Linux https://github.com/eloone/mergejs.

Compared to the above scripts it has the advantages of being very simple to use, and a big plus is that you can list the js files you want to merge in an input text file and not in the command line, so your list is reusable and you don't have to type it every time you want to merge your files. It's very handy since you will repeat this step every time you want to push into production. You can also comment files you don't want to merge in the list. The command line you would most likely type is :

$ mergejs js_files_list.txt output.js

And if you want to also compress the resulting merged file :

$ mergejs -c js_files_list.txt output.js

This will create output-min.js minified by Google's closure compiler. Or :

$ mergejs -c js_files_list.txt output.js output.minified.js

If you want a specific name for your minified file named output.minified.js

I find it really helpful for a simple website.

The most ideal way of doing this is found here: Fragment: which callback invoked when press back button & customize it

public class MyActivity extends Activity
{
    //...
    //Defined in Activity class, so override
    @Override
    public void onBackPressed()
    {
        super.onBackPressed();
        myFragment.onBackPressed();
    }
}

public class MyFragment extends Fragment
{
    //Your created method
    public static void onBackPressed()
    {
        //Pop Fragments off backstack and do your other checks
    }
}

get() returned more than one topic -- it returned 2!

The above error indicatess that you have more than one record in the DB related to the specific parameter you passed while querying using get() such as

Model.objects.get(field_name=some_param)

To avoid this kind of error in the future, you always need to do query as per your schema design. In your case you designed a table with a many-to-many relationship so obviously there will be multiple records for that field and that is the reason you are getting the above error.

So instead of using get() you should use filter() which will return multiple records. Such as

Model.objects.filter(field_name=some_param)

Please read about how to make queries in django here.

Combining my initial idea and your answers I reached what seems to be the solution to my own question:

public ProducerDTO findAndRemove(String pod) {
    ProducerDTO p = null;
    try {
        p = IntStream.range(0, producersProcedureActive.size())
             .filter(i -> producersProcedureActive.get(i).getPod().equals(pod))
             .boxed()
             .findFirst()
             .map(i -> producersProcedureActive.remove((int)i))
             .get();
        logger.debug(p);
    } catch (NoSuchElementException e) {
        logger.error("No producer found with POD [" + pod + "]");
    }
    return p;
}

It lets remove the object using remove(int) that do not traverse again the list (as suggested by @Tunaki) and it lets return the removed object to the function caller.

I read your answers that suggest me to choose safe methods like ifPresent instead of get but I do not find a way to use them in this scenario.

Are there any important drawback in this kind of solution?

Edit following @Holger advice

This should be the function I needed

public ProducerDTO findAndRemove(String pod) {
    return IntStream.range(0, producersProcedureActive.size())
            .filter(i -> producersProcedureActive.get(i).getPod().equals(pod))      
            .boxed()                                                                
            .findFirst()
            .map(i -> producersProcedureActive.remove((int)i))
            .orElseGet(() -> {
                logger.error("No producer found with POD [" + pod + "]"); 
                return null; 
            });
}

Here is an example showing some text in circles with data from a json file: http://bl.ocks.org/4474971. Which gives the following:

The main idea behind this is to encapsulate the text and the circle in the same "div" as you would do in html to have the logo and the name of the company in the same div in a page header.

The main code is:

var width = 960,
    height = 500;

var svg = d3.select("body").append("svg")
    .attr("width", width)
    .attr("height", height)

d3.json("data.json", function(json) {
    /* Define the data for the circles */
    var elem = svg.selectAll("g")
        .data(json.nodes)

    /*Create and place the "blocks" containing the circle and the text */  
    var elemEnter = elem.enter()
        .append("g")
        .attr("transform", function(d){return "translate("+d.x+",80)"})

    /*Create the circle for each block */
    var circle = elemEnter.append("circle")
        .attr("r", function(d){return d.r} )
        .attr("stroke","black")
        .attr("fill", "white")

    /* Create the text for each block */
    elemEnter.append("text")
        .attr("dx", function(d){return -20})
        .text(function(d){return d.label})
})

and the json file is:

{"nodes":[
  {"x":80, "r":40, "label":"Node 1"}, 
  {"x":200, "r":60, "label":"Node 2"}, 
  {"x":380, "r":80, "label":"Node 3"}
]}

The resulting html code shows the encapsulation you want:

<svg width="960" height="500">
    <g transform="translate(80,80)">
        <circle r="40" stroke="black" fill="white"></circle>
        <text dx="-20">Node 1</text>
    </g>
    <g transform="translate(200,80)">
        <circle r="60" stroke="black" fill="white"></circle>
        <text dx="-20">Node 2</text>
    </g>
    <g transform="translate(380,80)">
        <circle r="80" stroke="black" fill="white"></circle>
        <text dx="-20">Node 3</text>
    </g>
</svg>

This will work although when embedding PHP in HTML it is better practice to use the following form:

<table>
    <?php foreach($array as $key=>$value): ?>
    <tr>
        <td><?= $key; ?></td>
    </tr>
    <?php endforeach; ?>
</table>

You can find the doc for the alternative syntax on PHP.net

In my case, this was a bug in kotlin plugin, version 1.1.51

https://youtrack.jetbrains.com/issue/KT-20034

This error appeared on old devices (API 16).

Fixed this by removing @Parcelize annotations and replacing them with this code generator: https://github.com/nekocode/android-parcelable-intellij-plugin-kotlin

just do it: in component tree right click on ConstraintLayout and select relativelayout on convert view...

I was experiencing this problem even though my Theme was an AppCompat Theme and my Activity was an AppCompatActivity (or Activity, as suggested on other's answers). So I cleaned, rebuild and rerun the project.

(Build -> Clean Project ; Build -> Rebuild Project ; Run -> Run)

It may seem dumb, but now it works great!

Just hope it helps!

I am researching the same thing and stumbled upon identityserver which implements OAuth and OpenID on top of ASP.NET. It integrates with ASP.NET identity and Membership Reboot with persistence support for Entity Framework.

So, to answer your question, check out their detailed document on how to setup an OAuth and OpenID server.

Thanks a lot for the first answer.

As for me, I had just one problem with it. When inflating my view, i had a bug : java.lang.NoSuchMethodException : MyView(Context, Attributes)

I resolved it by creating a new constructor :

public MyView(Context context, AttributeSet attrs) {
     super(context, attrs);
     // some code
}

Hope this will help !

There are many other binaries that need to be linked so I think it's much better to try something like sudo update-alternatives --all and choosing the right alternatives for everything else besides java and javac.

The eval() function evaluates an expression, but "5+5" is a string, not an expression. Use parse() with text=<string> to change the string into an expression:

> eval(parse(text="5+5"))
[1] 10
> class("5+5")
[1] "character"
> class(parse(text="5+5"))
[1] "expression"

Calling eval() invokes many behaviours, some are not immediately obvious:

> class(eval(parse(text="5+5")))
[1] "numeric"
> class(eval(parse(text="gray")))
[1] "function"
> class(eval(parse(text="blue")))
Error in eval(expr, envir, enclos) : object 'blue' not found

Update 2020: This solution uses execCommand. While that feature was fine at the moment of writing this answer, it is now considered obsolete. It will still work on many browsers, but its use is discouraged as support may be dropped.

There is another non-Flash way (apart from the Clipboard API mentioned in jfriend00's answer). You need to select the text and then execute the command copy to copy to the clipboard whatever text is currently selected on the page.

For example, this function will copy the content of the passed element into the clipboard (updated with suggestion in the comments from PointZeroTwo):

function copyToClipboard(element) {
    var $temp = $("<input>");
    $("body").append($temp);
    $temp.val($(element).text()).select();
    document.execCommand("copy");
    $temp.remove();
}

This is how it works:

1. Creates a temporarily hidden text field.
2. Copies the content of the element to that text field.
3. Selects the content of the text field.
4. Executes the command copy like: document.execCommand("copy").
5. Removes the temporary text field.

NOTE that the inner text of the element can contain whitespace. So if you want to use if for example for passwords you may trim the text by using $(element).text().trim() in the code above.

You can see a quick demo here:

function copyToClipboard(element) {
  var $temp = $("<input>");
  $("body").append($temp);
  $temp.val($(element).text()).select();
  document.execCommand("copy");
  $temp.remove();
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<p id="p1">P1: I am paragraph 1</p>
<p id="p2">P2: I am a second paragraph</p>
<button onclick="copyToClipboard('#p1')">Copy P1</button>
<button onclick="copyToClipboard('#p2')">Copy P2</button>
<br/><br/><input type="text" placeholder="Paste here for test" />

The main issue is that not all browsers support this feature at the moment, but you can use it on the main ones from:

• Chrome 43
• Internet Explorer 10
• Firefox 41
• Safari 10

Update 1: This can be achieved also with a pure JavaScript solution (no jQuery):

function copyToClipboard(elementId) {

  // Create a "hidden" input
  var aux = document.createElement("input");

  // Assign it the value of the specified element
  aux.setAttribute("value", document.getElementById(elementId).innerHTML);

  // Append it to the body
  document.body.appendChild(aux);

  // Highlight its content
  aux.select();

  // Copy the highlighted text
  document.execCommand("copy");

  // Remove it from the body
  document.body.removeChild(aux);

}

<p id="p1">P1: I am paragraph 1</p>
<p id="p2">P2: I am a second paragraph</p>
<button onclick="copyToClipboard('p1')">Copy P1</button>
<button onclick="copyToClipboard('p2')">Copy P2</button>
<br/><br/><input type="text" placeholder="Paste here for test" />

Notice that we pass the id without the # now.

As madzohan reported in the comments below, there is some strange issue with the 64-bit version of Google Chrome in some cases (running the file locally). This issue seems to be fixed with the non-jQuery solution above.

Madzohan tried in Safari and the solution worked but using document.execCommand('SelectAll') instead of using .select() (as specified in the chat and in the comments below).

As PointZeroTwo points out in the comments, the code could be improved so it would return a success/failure result. You can see a demo on this jsFiddle.

UPDATE: COPY KEEPING THE TEXT FORMAT

As a user pointed out in the Spanish version of StackOverflow, the solutions listed above work perfectly if you want to copy the content of an element literally, but they don't work that great if you want to paste the copied text with format (as it is copied into an input type="text", the format is "lost").

A solution for that would be to copy into a content editable div and then copy it using the execCommand in a similar way. Here there is an example - click on the copy button and then paste into the content editable box below:

function copy(element_id){
  var aux = document.createElement("div");
  aux.setAttribute("contentEditable", true);
  aux.innerHTML = document.getElementById(element_id).innerHTML;
  aux.setAttribute("onfocus", "document.execCommand('selectAll',false,null)"); 
  document.body.appendChild(aux);
  aux.focus();
  document.execCommand("copy");
  document.body.removeChild(aux);
}

#target {
  width:400px;
  height:100px;
  border:1px solid #ccc;
}

<p id="demo"><b>Bold text</b> and <u>underlined text</u>.</p>
<button onclick="copy('demo')">Copy Keeping Format</button> 

<div id="target" contentEditable="true"></div>

And in jQuery, it would be like this:

function copy(selector){
  var $temp = $("<div>");
  $("body").append($temp);
  $temp.attr("contenteditable", true)
       .html($(selector).html()).select()
       .on("focus", function() { document.execCommand('selectAll',false,null); })
       .focus();
  document.execCommand("copy");
  $temp.remove();
}

#target {
  width:400px;
  height:100px;
  border:1px solid #ccc;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

<p id="demo"><b>Bold text</b> and <u>underlined text</u>.</p>
<button onclick="copy('#demo')">Copy Keeping Format</button> 

<div id="target" contentEditable="true"></div>

Set it as Global Default

ng set defaults.styleExt=scss --global

Services are quite complicated sometimes.

When you start a service from an activity (or your process), the service is essentially on the same process.

quoting from the developer notes

Most confusion about the Service class actually revolves around what it is not:

A Service is not a separate process. The Service object itself does not imply it is running in its own process; unless otherwise specified, it runs in the same process as the application it is part of.

A Service is not a thread. It is not a means itself to do work off of the main thread (to avoid Application Not Responding errors).

So, what this means is, if the user swipes the app away from the recent tasks it will delete your process(this includes all your activities etc). Now, lets take three scenarios.

First where the service does not have a foreground notification.

In this case your process is killed along with your service.

Second where the service has a foreground notification

In this case the service is not killed and neither is the process

Third scenario If the service does not have a foreground notification, it can still keep running if the app is closed. We can do this by making the service run in a different process. (However, I've heard some people say that it may not work. left to you to try it out yourself)

you can create a service in a separate process by including the below attribute in your manifest.

android:process=":yourService"

or

android:process="yourService" process name must begin with lower case.

quoting from developer notes

If the name assigned to this attribute begins with a colon (':'), a new process, private to the application, is created when it's needed and the service runs in that process. If the process name begins with a lowercase character, the service will run in a global process of that name, provided that it has permission to do so. This allows components in different applications to share a process, reducing resource usage.

this is what I have gathered, if anyone is an expert, please do correct me if I'm wrong :)

I suggest that you take a look at the Java docs for these methods. It appears that you are using them incorrectly. These methods will not tell you if the string is a valid boolean value, but instead they return a boolean, set to true or false, based on the string that you pass in, "true" or "false".

        if s[s_len] in ('aeiou'):
            cnt += 1
        s_len -= 1
    print 'numofVowels: ' + str(cnt)
    return cnt

package-lock.json is automatically generated for any operations where npm modifies either the node_modules tree, or package.json. It describes the exact tree that was generated, such that subsequent installs are able to generate identical trees, regardless of intermediate dependency updates.

It describes a single representation of a dependency tree such that teammates, deployments, and continuous integration are guaranteed to install exactly the same dependencies.It contains the following properties.

{
    "name": "mobileapp",
    "version": "1.0.0",
    "lockfileVersion": 1,

You should use .NET Core, instead of .NET Framework or Xamarin, in the following 6 typical scenarios according to the documentation here.

1. Cross-Platform needs

Clearly, if your goal is to have an application (web/service) that should be able to run across platforms (Windows, Linux and MacOS), the best choice in the .NET ecosystem is to use .NET Core as its runtime (CoreCLR) and libraries are cross-platform. The other choice is to use the Mono Project.

Both choices are open source, but .NET Core is directly and officially supported by Microsoft and will have a heavy investment moving forward.

When using .NET Core across platforms, the best development experience exists on Windows with the Visual Studio IDE which supports many productivity features including project management, debugging, source control, refactoring, rich editing including Intellisense, testing and much more. But rich development is also supported using Visual Studio Code on Mac, Linux and Windows including intellisense and debugging. Even third party editors like Sublime, Emacs, VI and more work well and can get editor intellisense using the open source Omnisharp project.

2. Microservices

When you are building a microservices oriented system composed of multiple independent, dynamically scalable, stateful or stateless microservices, the great advantage that you have here is that you can use different technologies/frameworks/languages at a microservice level. That allows you to use the best approach and technology per micro areas in your system, so if you want to build very performant and scalable microservices, you should use .NET Core. Eventually, if you need to use any .NET Framework library that is not compatible with .NET Core, there’s no issue, you can build that microservice with the .NET Framework and in the future you might be able to substitute it with the .NET Core.

The infrastructure platform you could use are many. Ideally, for large and complex microservice systems, you should use Azure Service Fabric. But for stateless microservices you can also use other products like Azure App Service or Azure Functions.

Note that as of June 2016, not every technology within Azure supports the .NET Core, but .NET Core support in Azure will be increasing dramatically now that .NET Core is RTM released.

3. Best performant and scalable systems

When your system needs the best possible performance and scalability so you get the best responsiveness no matter how many users you have, then is where .NET Core and ASP.NET Core really shine. The more you can do with the same amount of infrastructure/hardware, the richer the experience you’ll have for your end users – at a lower cost.

The days of Moore’s law performance improvements for single CPUs does not apply anymore; yet you need to do more while your system is growing and need higher scalability and performance for everyday’ s more demanding users which are growing exponentially in numbers. You need to get more efficient, optimize everywhere, and scale better across clusters of machines, VMs and CPU cores, ultimately. It is not just a matter of user’s satisfaction; it can also make a huge difference in cost/TCO. This is why it is important to strive for performance and scalability.

As mentioned, if you can isolate small pieces of your system as microservices or any other loosely-coupled approach, it’ll be better as you’ll be able to not just evolve each small piece/microservice independently and have a better long-term agility and maintenance, but also you’ll be able to use any other technology at a microservice level if what you need to do is not compatible with .NET Core. And eventually you’d be able to refactor it and bring it to .NET Core when possible.

4. Command line style development for Mac, Linux or Windows.

This approach is optional when using .NET Core. You can also use the full Visual Studio IDE, of course. But if you are a developer that wants to develop with lightweight editors and heavy use of command line, .NET Core is designed for CLI. It provides simple command line tools available on all supported platforms, enabling developers to build and test applications with a minimal installation on developer, lab or production machines. Editors like Visual Studio Code use the same command line tools for their development experiences. And IDE’s like Visual Studio use the same CLI tools but hide them behind a rich IDE experience. Developers can now choose the level they want to interact with the tool chain from CLI to editor to IDE.

5. Need side by side of .NET versions per application level.

If you want to be able to install applications with dependencies on different versions of frameworks in .NET, you need to use .NET Core which provides 100% side-by side as explained previously in this document.

6. Windows 10 UWP .NET apps.

In addition, you may also want to read:

1. When should I NOT use .NET Core?
2. When should I still use .NET Framework 4.x, instead of .NET Core?
3. When should I use Xamarin, instead of .NET Core?

== Equality operator evaluates the arguments after converting them to numbers. So string zero "0" is converted to Number data type and boolean false is converted to Number 0. So

"0" == false // true

Same applies to `

false == "0" //true

=== Strict equality check evaluates the arguments with the original data type

"0" === false // false, because "0" is a string and false is boolean

Same applies to

false === "0" // false

In

if("0") console.log("ha");

The String "0" is not comparing with any arguments, and string is a true value until or unless it is compared with any arguments. It is exactly like

if(true) console.log("ha");

But

if (0) console.log("ha"); // empty console line, because 0 is false

`

JavaScript will get the job done.

Get all links in the document and compare their reference URLs to the document's URL. If there is a match, add a class to that link.

JavaScript

<script>
    currentLinks = document.querySelectorAll('a[href="'+document.URL+'"]')
    currentLinks.forE??ach(function(link) {
        link.className += ' current-link')
    });
</script>

One Liner Version of Above

document.querySelectorAll('a[href="'+document.URL+'"]').forE??ach(function(elem){e??lem.className += ' current-link')});

CSS

.current-link {
    color:#baada7;
}

Other Notes

Taraman's jQuery answer above only searches on [href] which will return link tags and tags other than a which rely on the href attribute. Searching on a[href='*https://urlofcurrentpage.com*'] captures only those links which meets the criteria and therefore runs faster.

In addtion, if you don't need to rely on the jQuery library, a vanilla JavaScript solution is definitely the way to go.

This might happen if you place .cs files in App_Code and changed their build action to compile in a Web Application Project.

Either have the build action for the .cs files in App_Code as Content or change the name of App_Code to something else. I changed the name since intellisense won't fix .cs files marked as content.

It is important to recognize that the copyright laws have changed and that for non-US sources, especially after the USA joining the Berne Convention on March 1, 1989, copyright registration in not necessary for enforcement of a copyright notice.
Here is a resumé quoted from the Cornell University Law School (copied on March 4, 2015 from https://www.law.cornell.edu/wex/copyright:

"Copyright copyright: an overview

The U.S. Copyright Act, 17 U.S.C. §§ 101 - 810, is Federal legislation enacted by Congress under its Constitutional grant of authority to protect the writings of authors. See U.S. Constitution, Article I, Section 8. Changing technology has led to an ever expanding understanding of the word "writings." The Copyright Act now reaches architectural design, software, the graphic arts, motion pictures, and sound recordings. See § 106. As of January 1, 1978, all works of authorship fixed in a tangible medium of expression and within the subject matter of copyright were deemed to fall within the exclusive jurisdiction of the Copyright Act regardless of whether the work was created before or after that date and whether published or unpublished. See § 301. See also preemption.

The owner of a copyright has the exclusive right to reproduce, distribute, perform, display, license, and to prepare derivative works based on the copyrighted work. See § 106. The exclusive rights of the copyright owner are subject to limitation by the doctrine of "fair use." See § 107. Fair use of a copyrighted work for purposes such as criticism, comment, news reporting, teaching, scholarship, or research is not copyright infringement. To determine whether or not a particular use qualifies as fair use, courts apply a multi-factor balancing test. See § 107.

Copyright protection subsists in original works of authorship fixed in any tangible medium of expression from which they can be perceived, reproduced, or otherwise communicated, either directly or with the aid of a machine or device. See § 102. Copyright protection does not extend to any idea, procedure, process, system, method of operation, concept, principle, or discovery. For example, if a book is written describing a new system of bookkeeping, copyright protection only extends to the author's description of the bookkeeping system; it does not protect the system itself. See Baker v. Selden, 101 U.S. 99 (1879).

According to the Copyright Act of 1976, registration of copyright is voluntary and may take place at any time during the term of protection. See § 408. Although registration of a work with the Copyright Office is not a precondition for protection, an action for copyright infringement may not be commenced until the copyright has been formally registered with the Copyright Office. See § 411.

Deposit of copies with the Copyright Office for use by the Library of Congress is a separate requirement from registration. Failure to comply with the deposit requirement within three months of publication of the protected work may result in a civil fine. See § 407. The Register of Copyrights may exempt certain categories of material from the deposit requirement.

In 1989 the U.S. joined the Berne Convention for the Protection of Literary and Artistic Works. In accordance with the requirements of the Berne Convention, notice is no longer a condition of protection for works published after March 1, 1989. This change to the notice requirement applies only prospectively to copies of works publicly distributed after March 1, 1989.

The Berne Convention also modified the rule making copyright registration a precondition to commencing a lawsuit for infringement. For works originating from a Berne Convention country, an infringement action may be initiated without registering the work with the U.S. Copyright Office. However, for works of U.S. origin, registration prior to filing suit is still required.

The federal agency charged with administering the act is the Copyright Office of the Library of Congress. See § 701 of the act. Its regulations are found in Parts 201 - 204 of title 37 of the Code of Federal Regulations."

I tested a few solutions an found that

Select *
From INFORMATION_SCHEMA.COLUMNS

gives you the column info for your CURRENT/default database.

Select *
From <DBNAME>.INFORMATION_SCHEMA.COLUMNS

, without the < and >, gives you the column info for the database DBNAME.

If you are using redux you can do this in a very elegant way with middleware. You can define a Debounce middleware as:

var timeout;
export default store => next => action => {
  const { meta = {} } = action;
  if(meta.debounce){
    clearTimeout(timeout);
    timeout = setTimeout(() => {
      next(action)
    }, meta.debounce)
  }else{
    next(action)
  }
}

You can then add debouncing to action creators, such as:

export default debouncedAction = (payload) => ({
  type : 'DEBOUNCED_ACTION',
  payload : payload,
  meta : {debounce : 300}
}

There's actually already middleware you can get off npm to do this for you.

Use the 'And' keyword for a logical and. Like this:

If Not ((filename = testFileName) And (fileName <> "")) Then

org.apache.commons.lang3.StringEscapeUtils from commons-lang3 is marked deprecated now. You can use org.apache.commons.text.StringEscapeUtils#unescapeJava(String) instead. It requires an additional Maven dependency:

        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-text</artifactId>
            <version>1.4</version>
        </dependency>

and seems to handle some more special cases, it e.g. unescapes:

• escaped backslashes, single and double quotes
• escaped octal and unicode values
• \\b, \\n, \\t, \\f, \\r

If the concrete methods invoke any of the abstract methods that strategy won't work, and you'd want to test each child class behavior separately. Otherwise, extending it and stubbing the abstract methods as you've described should be fine, again provided the abstract class concrete methods are decoupled from child classes.

Along the same lines as @Eric's answer, but without using a 'NULL' symbol.

(Field1 = Field2) OR (ISNULL(Field1, Field2) IS NULL)

This will be true only if both values are non-NULL, and equal each other, or both values are NULL

You have also to ensure you have the correct SDK platform version installed in your environment by using SDK Manager.

it's :

vbnewline

for example

Msgbox ("Fst line" & vbnewline & "second line")

The error message basically means that the programmer is unable to contact the bootloader on the device; the code you're trying to upload has no bearing on the problem.

What causes this can be numerous and varied, some possible issues:

1. UART communications

   • Blinking is happening, so hopefully you aren't using the wrong port. It might be worth checking again though, sometimes USB COM devices install on strange port numbers.

   • Connect TX to RX (and disconnect them from the AVR if possible) then open a terminal on the COM port, you should see characters echoed if you type them. If you don't, something is wrong up-stream of the chip, it could be the communications chip (I think the Arduino 2560 uses a secondary AVR instead of an FTDI for some reason, so that could be broken, either its software or hardware)

2. ATmega* bootloader

   • The AVR is not executing the bootloader for some reason. If the programmer is not resetting the micro before attempting to connect, this might be the reason. Try to reset the AVR (press and release the button) while the programmer is attempting to connect. Sometimes software that runs in a tight loop will prevent the bootloader from connecting.

   • Barring that, the fuses might have gotten messed up or the code erased. You would need to reflash the bootloader and proper fuses, again, see the appropriate info page for your device.

3. Arduino Mega 2560 only: ATmega8U/16U software

   • Might not be working and would need reprogramming. See the Programming section on the info page, you will need the firmware and Atmel-compatible DFU (device firmware update) software on your computer to reflash the target.

4. Hardware damage to the board, AVR(s), or FTDI chip

   • You're hosed; need a new chip.

we can upload image file by curl request by converting it base64 string.So in post we will send file string and then covert this in an image.

function covertImageInBase64()
{
    var imageFile = document.getElementById("imageFile").files;
    if (imageFile.length > 0)
    {
        var imageFileUpload = imageFile[0];
        var readFile = new FileReader();
        readFile.onload = function(fileLoadedEvent) 
        {
            var base64image = document.getElementById("image");
            base64image.value = fileLoadedEvent.target.result;
        };
        readFile.readAsDataURL(imageFileUpload);
    }
}

then send it in curl request

if(isset($_POST['image'])){
    $curlUrl='localhost/curlfile.php';  
    $ch = curl_init();
    curl_setopt($ch,CURLOPT_URL, $curlUrl);
    curl_setopt($ch,CURLOPT_POST, 1);
    curl_setopt($ch,CURLOPT_POSTFIELDS, 'image='.$_POST['image']);
    $result = curl_exec($ch);
    curl_close($ch);
}

use the command prompt, as suggested. I figured out why explorer is so slow a while ago, it gives you an estimate of how long it will take to delete the files/folders. To do this, it has to scan the number of items and the size. This takes ages, hence the ridiculous wait with large folders.

Also, explorer will stop if there is a particular problem with a file,

You need to set figure properties.

At the very beginning of the script, call

figure('name','something else')

Calling figure is a good thing, anyway, because without it, you always plot into the same window, and sometimes you may want to compare two windows side-by-side.

Alternatively, you can store the figure's handle by calling

figH = figure;

so that you can later change the figure properties to your liking (the 'numberTitle' property setting eliminates the "figure X" text)

set(figH,'Name','something else','NumberTitle','off')

Have a look at the figure properties in the MATLAB documentation to see what else you can change if you want.

It's probably easier to create your keys under linux and use PuTTYgen to convert the keys to PuTTY format.

PuTTY Faq: A.2.2

As @Alexander solves, the issue is one of async data load - you're rendering immediately and you will not have participants loaded until the async ajax call resolves and populates data with participants.

The alternative to the solution they provided would be to prevent render until participants exist, something like this:

    render: function() {
        if (!this.props.data.participants) {
            return null;
        }
        return (
            <ul className="PlayerList">
            // I'm the Player List {this.props.data}
            // <Player author="The Mini John" />
            {
                this.props.data.participants.map(function(player) {
                    return <li key={player}>{player}</li>
                })
            }
            </ul>
        );
    }

../ is one directory, Repeat for two directories ../../ or even three: ../../../ and so on.

Defining constants may reduce confusion because you will drill forward into directories verses backwards

You could define some constants like so:

define('BD', '/home/user/public_html/example/');

define('HTMLBD', 'http://example.com/');

When using 'BD' or my 'base directory' it looks like so:

file(BD.'location/of/file.php');

define(); reference

If you listen this channel you always can findout that channel was closed.

case state, opened := <-ws:
    if !opened {
         // channel was closed 
         // return or made some final work
    }
    switch state {
        case Stopped:

But remember, you can not close one channel two times. This will raise panic.

I was getting the same UnicodeEncodeError when saving scraped web content to a file. To fix it I replaced this code:

with open(fname, "w") as f:
    f.write(html)

with this:

import io
with io.open(fname, "w", encoding="utf-8") as f:
    f.write(html)

Using io gives you backward compatibility with Python 2.

If you only need to support Python 3 you can use the builtin open function instead:

with open(fname, "w", encoding="utf-8") as f:
    f.write(html)

You almost got it. It should be this:

<input type="radio" name="group1" id="r1" value="1" />_x000D_
<label for="r1"> button one</label>

The value in for should be the id of the element you are labeling.

What is the real difference between one-to-many and many-to-one relationship?

There are conceptual differences between these terms that should help you visualize the data and also possible differences in the generated schema that should be fully understood. Mostly the difference is one of perspective though.

In a one-to-many relationship, the local table has one row that may be associated with many rows in another table. In the example from SQL for beginners, one Customer may be associated to many Orders.

In the opposite many-to-one relationship, the local table may have many rows that are associated with one row in another table. In our example, many Orders may be associated to one Customer. This conceptual difference is important for mental representation.

In addition, the schema which supports the relationship may be represented differently in the Customer and Order tables. For example, if the customer has columns id and name:

id,name
1,Bill Smith
2,Jim Kenshaw

Then for a Order to be associated with a Customer, many SQL implementations add to the Order table a column which stores the id of the associated Customer (in this schema customer_id:

id,date,amount,customer_id
10,20160620,12.34,1
11,20160620,7.58,1
12,20160621,158.01,2

In the above data rows, if we look at the customer_id id column, we see that Bill Smith (customer-id #1) has 2 orders associated with him: one for $12.34 and one for $7.58. Jim Kenshaw (customer-id #2) has only 1 order for $158.01.

What is important to realize is that typically the one-to-many relationship doesn't actually add any columns to the table that is the "one". The Customer has no extra columns which describe the relationship with Order. In fact the Customer might also have a one-to-many relationship with ShippingAddress and SalesCall tables and yet have no additional columns added to the Customer table.

However, for a many-to-one relationship to be described, often an id column is added to the "many" table which is a foreign-key to the "one" table -- in this case a customer_id column is added to the Order. To associated order #10 for $12.34 to Bill Smith, we assign the customer_id column to Bill Smith's id 1.

However, it is also possible for there to be another table that describes the Customer and Order relationship, so that no additional fields need to be added to the Order table. Instead of adding a customer_id field to the Order table, there could be Customer_Order table that contains keys for both the Customer and Order.

customer_id,order_id
1,10
1,11
2,12

In this case, the one-to-many and many-to-one is all conceptual since there are no schema changes between them. Which mechanism depends on your schema and SQL implementation.

Hope this helps.

You were just missing the second half of the column statement telling it to remove the entire column, since most normal Ranges start with a Column Letter, it was looking for a number and didn't get one. The ":" gets the whole column, or row.

I think what you were looking for in your Range was this:

Range("C:C,F:F,I:I,L:L,O:O,R:R").Delete

Just change the column letters to match your needs.

You are using a table variable i.e. you should declare the table. This is not a temporary table.

You create a temp table like so:

CREATE TABLE #customer
(
     Name varchar(32) not null
)

You declare a table variable like so:

DECLARE @Customer TABLE
(
      Name varchar(32) not null
)

Notice that a temp table is declared using # and a table variable is declared using a @. Go read about the difference between table variables and temp tables.

UPDATE:

Based on your comment below you are actually trying to create tables in a stored procedure. For this you would need to use dynamic SQL. Basically dynamic SQL allows you to construct a SQL Statement in the form of a string and then execute it. This is the ONLY way you will be able to create a table in a stored procedure. I am going to show you how and then discuss why this is not generally a good idea.

Now for a simple example (I have not tested this code but it should give you a good indication of how to do it):

CREATE PROCEDURE sproc_BuildTable 
    @TableName NVARCHAR(128)
   ,@Column1Name NVARCHAR(32)
   ,@Column1DataType NVARCHAR(32)
   ,@Column1Nullable NVARCHAR(32)
AS

   DECLARE @SQLString NVARCHAR(MAX)
   SET @SQString = 'CREATE TABLE '+@TableName + '( '+@Column1Name+' '+@Column1DataType +' '+@Column1Nullable +') ON PRIMARY '

   EXEC (@SQLString)
   GO

This stored procedure can be executed like this:

sproc_BuildTable 'Customers','CustomerName','VARCHAR(32)','NOT NULL'

There are some major problems with this type of stored procedure.

Its going to be difficult to cater for complex tables. Imagine the following table structure:

CREATE TABLE [dbo].[Customers] (
    [CustomerID] [int] IDENTITY(1,1) NOT NULL,
    [CustomerName] [nvarchar](64) NOT NULL,
    [CustomerSUrname] [nvarchar](64) NOT NULL,
    [CustomerDateOfBirth] [datetime] NOT NULL,
    [CustomerApprovedDiscount] [decimal](3, 2) NOT NULL,
    [CustomerActive] [bit] NOT NULL,
    CONSTRAINT [PK_Customers] PRIMARY KEY CLUSTERED 
    (
        [CustomerID] ASC
    ) WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF,      ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

ALTER TABLE [dbo].[Customers] ADD CONSTRAINT [DF_Customers_CustomerApprovedDiscount] DEFAULT ((0.00)) FOR [CustomerApprovedDiscount]
GO 

This table is a little more complex than the first example, but not a lot. The stored procedure will be much, much more complex to deal with. So while this approach might work for small tables it is quickly going to be unmanageable.

Creating tables require planning. When you create tables they should be placed strategically on different filegroups. This is to ensure that you don't cause disk I/O contention. How will you address scalability if everything is created on the primary file group?

Could you clarify why you need tables to be created dynamically?

UPDATE 2:

Delayed update due to workload. I read your comment about needing to create a table for each shop and I think you should look at doing it like the example I am about to give you.

In this example I make the following assumptions:

1. It's an e-commerce site that has many shops
2. A shop can have many items (goods) to sell.
3. A particular item (good) can be sold at many shops
4. A shop will charge different prices for different items (goods)
5. All prices are in $ (USD)

Let say this e-commerce site sells gaming consoles (i.e. Wii, PS3, XBOX360).

Looking at my assumptions I see a classical many-to-many relationship. A shop can sell many items (goods) and items (goods) can be sold at many shops. Let's break this down into tables.

First I would need a shop table to store all the information about the shop.

A simple shop table might look like this:

CREATE TABLE [dbo].[Shop](
    [ShopID] [int] IDENTITY(1,1) NOT NULL,
    [ShopName] [nvarchar](128) NOT NULL,
    CONSTRAINT [PK_Shop] PRIMARY KEY CLUSTERED 
    (
      [ShopID] ASC
    ) WITH (
              PAD_INDEX  = OFF
              , STATISTICS_NORECOMPUTE  = OFF
              , IGNORE_DUP_KEY = OFF
              , ALLOW_ROW_LOCKS  = ON
              , ALLOW_PAGE_LOCKS  = ON
    ) ON [PRIMARY]
    ) ON [PRIMARY]

    GO

Let's insert three shops into the database to use during our example. The following code will insert three shops:

INSERT INTO Shop
SELECT 'American Games R US'
UNION
SELECT 'Europe Gaming Experience'
UNION
SELECT 'Asian Games Emporium'

If you execute a SELECT * FROM Shop you will probably see the following:

ShopID  ShopName
1           American Games R US
2           Asian Games Emporium
3           Europe Gaming Experience

Right, so now let's move onto the Items (goods) table. Since the items/goods are products of various companies I am going to call the table product. You can execute the following code to create a simple Product table.

CREATE TABLE [dbo].[Product](
    [ProductID] [int] IDENTITY(1,1) NOT NULL,
    [ProductDescription] [nvarchar](128) NOT NULL,
 CONSTRAINT [PK_Product] PRIMARY KEY CLUSTERED 
 (
     [ProductID] ASC
 )WITH (PAD_INDEX  = OFF
        , STATISTICS_NORECOMPUTE  = OFF
        , IGNORE_DUP_KEY = OFF
        ,     ALLOW_ROW_LOCKS  = ON
         , ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
  ) ON [PRIMARY]

GO

Let's populate the products table with some products. Execute the following code to insert some products:

INSERT INTO Product
SELECT 'Wii'
UNION 
SELECT 'PS3'
UNION 
SELECT 'XBOX360'

If you execute SELECT * FROM Product you will probably see the following:

ProductID   ProductDescription
1           PS3
2           Wii
3           XBOX360

OK, at this point you have both product and shop information. So how do you bring them together? Well we know we can identify the shop by its ShopID primary key column and we know we can identify a product by its ProductID primary key column. Also, since each shop has a different price for each product we need to store the price the shop charges for the product.

So we have a table that maps the Shop to the product. We will call this table ShopProduct. A simple version of this table might look like this:

CREATE TABLE [dbo].[ShopProduct](
[ShopID] [int] NOT NULL,
[ProductID] [int] NOT NULL,
[Price] [money] NOT NULL,
CONSTRAINT [PK_ShopProduct] PRIMARY KEY CLUSTERED 
 (
     [ShopID] ASC,
      [ProductID] ASC
 )WITH (PAD_INDEX  = OFF,
     STATISTICS_NORECOMPUTE  = OFF, 
     IGNORE_DUP_KEY = OFF, 
     ALLOW_ROW_LOCKS  = ON,
     ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
  ) ON [PRIMARY]

 GO

So let's assume the American Games R Us shop only sells American consoles, the Europe Gaming Experience sells all consoles and the Asian Games Emporium sells only Asian consoles. We would need to map the primary keys from the shop and product tables into the ShopProduct table.

Here is how we are going to do the mapping. In my example the American Games R Us has a ShopID value of 1 (this is the primary key value) and I can see that the XBOX360 has a value of 3 and the shop has listed the XBOX360 for $159.99

By executing the following code you would complete the mapping:

INSERT INTO ShopProduct VALUES(1,3,159.99)

Now we want to add all product to the Europe Gaming Experience shop. In this example we know that the Europe Gaming Experience shop has a ShopID of 3 and since it sells all consoles we will need to insert the ProductID 1, 2 and 3 into the mapping table. Let's assume the prices for the consoles (products) at the Europe Gaming Experience shop are as follows: 1- The PS3 sells for $259.99 , 2- The Wii sells for $159.99 , 3- The XBOX360 sells for $199.99.

To get this mapping done you would need to execute the following code:

INSERT INTO ShopProduct VALUES(3,2,159.99) --This will insert the WII console into the mapping table for the Europe Gaming Experience Shop with a price of 159.99
INSERT INTO ShopProduct VALUES(3,1,259.99) --This will insert the PS3 console into the mapping table for the Europe Gaming Experience Shop with a price of 259.99
INSERT INTO ShopProduct VALUES(3,3,199.99) --This will insert the XBOX360 console into the mapping table for the Europe Gaming Experience Shop with a price of 199.99

At this point you have mapped two shops and their products into the mapping table. OK, so now how do I bring this all together to show a user browsing the website? Let's say you want to show all the product for the European Gaming Experience to a user on a web page – you would need to execute the following query:

SELECT      Shop.*
        , ShopProduct.*
        , Product.*
FROM         Shop 
INNER JOIN  ShopProduct ON Shop.ShopID = ShopProduct.ShopID 
INNER JOIN  Product ON ShopProduct.ProductID = Product.ProductID
WHERE       Shop.ShopID=3

You will probably see the following results:

ShopID     ShopName                 ShopID  ProductID   Price   ProductID   ProductDescription
3          Europe Gaming Experience   3         1       259.99  1           PS3
3          Europe Gaming Experience   3         2       159.99  2           Wii
3          Europe Gaming Experience   3         3       199.99  3           XBOX360

Now for one last example, let's assume that your website has a feature which finds the cheapest price for a console. A user asks to find the cheapest prices for XBOX360.

You can execute the following query:

 SELECT     Shop.*
        , ShopProduct.*
        , Product.*
 FROM         Shop 
 INNER JOIN  ShopProduct ON Shop.ShopID = ShopProduct.ShopID 
 INNER JOIN  Product ON ShopProduct.ProductID = Product.ProductID
 WHERE      Product.ProductID =3  -- You can also use Product.ProductDescription = 'XBOX360'
 ORDER BY    Price ASC

This query will return a list of all shops which sells the XBOX360 with the cheapest shop first and so on.

You will notice that I have not added the Asian Games shop. As an exercise, add the Asian games shop to the mapping table with the following products: the Asian Games Emporium sells the Wii games console for $99.99 and the PS3 console for $159.99. If you work through this example you should now understand how to model a many-to-many relationship.

I hope this helps you in your travels with database design.

In Selenium to get the URL of the active tab try,

from selenium import webdriver

driver = webdriver.Firefox()
print driver.current_url # This will print the URL of the Active link

Sending a signal to change the tab

driver.find_element_by_tag_name('body').send_keys(Keys.CONTROL + Keys.TAB)

and again use

print driver.current_url

I am here just providing a pseudo code for you.

You can put this in a loop and create your own flow.

I new to Stackoverflow so still learning how to write proper answers.

Idle Timeout is if no action has been asked from your web app, it the process will drop and release everything from memory

Recycle is a forced action on the application where your processed is closed and started again, for memory leaking purposes and system health

The negative impact of both is usually the use of your Session and Application state is lost if you mess with Recycle to a faster time.(logged in users etc will be logged out, if they where about to "check out" all would have been lost" that's why recycle is at such a large time out value, idle timeout doesn't matter because nobody is logged in anyway and figure 20 minutes an no action they are not still "shopping"

The positive would be get rid of the idle time out as your website will respond faster on its "first" response if its not a highly active site where a user would have to wait for it to load if you have 1 user every 20 minutes lets say. So a website that get his less then 1 time in 20 minutes actually you would want to increase this value as the website has to load up again from scratch for each user. but if you set this to 0 over a long time, any memory leaks in code could over a certain amount of time, entirely take over the server.

I would recomment Pluralsight's tool for creating self-signed-certs: http://blog.pluralsight.com/selfcert-create-a-self-signed-certificate-interactively-gui-or-programmatically-in-net

Make your cert as a .pfx and import it into IIS. And add it as a trusted root cert authority.

ClassPath:

ClassPath is affected depending on what you provide. There are a couple of ways to set something on the classpath:

• spark.driver.extraClassPath or it's alias --driver-class-path to set extra classpaths on the node running the driver.
• spark.executor.extraClassPath to set extra class path on the Worker nodes.

If you want a certain JAR to be effected on both the Master and the Worker, you have to specify these separately in BOTH flags.

Separation character:

Following the same rules as the JVM:

• Linux: A colon :
  • e.g: --conf "spark.driver.extraClassPath=/opt/prog/hadoop-aws-2.7.1.jar:/opt/prog/aws-java-sdk-1.10.50.jar"
• Windows: A semicolon ;
  • e.g: --conf "spark.driver.extraClassPath=/opt/prog/hadoop-aws-2.7.1.jar;/opt/prog/aws-java-sdk-1.10.50.jar"

File distribution:

This depends on the mode which you're running your job under:

1. Client mode - Spark fires up a Netty HTTP server which distributes the files on start up for each of the worker nodes. You can see that when you start your Spark job:

   16/05/08 17:29:12 INFO HttpFileServer: HTTP File server directory is /tmp/spark-48911afa-db63-4ffc-a298-015e8b96bc55/httpd-84ae312b-5863-4f4c-a1ea-537bfca2bc2b
   16/05/08 17:29:12 INFO HttpServer: Starting HTTP Server
   16/05/08 17:29:12 INFO Utils: Successfully started service 'HTTP file server' on port 58922.
   16/05/08 17:29:12 INFO SparkContext: Added JAR /opt/foo.jar at http://***:58922/jars/com.mycode.jar with timestamp 1462728552732
   16/05/08 17:29:12 INFO SparkContext: Added JAR /opt/aws-java-sdk-1.10.50.jar at http://***:58922/jars/aws-java-sdk-1.10.50.jar with timestamp 1462728552767
   

2. Cluster mode - In cluster mode spark selected a leader Worker node to execute the Driver process on. This means the job isn't running directly from the Master node. Here, Spark will not set an HTTP server. You have to manually make your JARS available to all the worker node via HDFS/S3/Other sources which are available to all nodes.

Accepted URI's for files

In "Submitting Applications", the Spark documentation does a good job of explaining the accepted prefixes for files:

When using spark-submit, the application jar along with any jars included with the --jars option will be automatically transferred to the cluster. Spark uses the following URL scheme to allow different strategies for disseminating jars:

• file: - Absolute paths and file:/ URIs are served by the driver’s HTTP file server, and every executor pulls the file from the driver HTTP server.
• hdfs:, http:, https:, ftp: - these pull down files and JARs from the URI as expected
• local: - a URI starting with local:/ is expected to exist as a local file on each worker node. This means that no network IO will be incurred, and works well for large files/JARs that are pushed to each worker, or shared via NFS, GlusterFS, etc.

Note that JARs and files are copied to the working directory for each SparkContext on the executor nodes.

As noted, JARs are copied to the working directory for each Worker node. Where exactly is that? It is usually under /var/run/spark/work, you'll see them like this:

drwxr-xr-x    3 spark spark   4096 May 15 06:16 app-20160515061614-0027
drwxr-xr-x    3 spark spark   4096 May 15 07:04 app-20160515070442-0028
drwxr-xr-x    3 spark spark   4096 May 15 07:18 app-20160515071819-0029
drwxr-xr-x    3 spark spark   4096 May 15 07:38 app-20160515073852-0030
drwxr-xr-x    3 spark spark   4096 May 15 08:13 app-20160515081350-0031
drwxr-xr-x    3 spark spark   4096 May 18 17:20 app-20160518172020-0032

And when you look inside, you'll see all the JARs you deployed along:

Affected options:

The most important thing to understand is priority. If you pass any property via code, it will take precedence over any option you specify via spark-submit. This is mentioned in the Spark documentation:

Any values specified as flags or in the properties file will be passed on to the application and merged with those specified through SparkConf. Properties set directly on the SparkConf take highest precedence, then flags passed to spark-submit or spark-shell, then options in the spark-defaults.conf file

So make sure you set those values in the proper places, so you won't be surprised when one takes priority over the other.

Lets analyze each option in question:

• --jars vs SparkContext.addJar: These are identical, only one is set through spark submit and one via code. Choose the one which suites you better. One important thing to note is that using either of these options does not add the JAR to your driver/executor classpath, you'll need to explicitly add them using the extraClassPath config on both.
• SparkContext.addJar vs SparkContext.addFile: Use the former when you have a dependency that needs to be used with your code. Use the latter when you simply want to pass an arbitrary file around to your worker nodes, which isn't a run-time dependency in your code.
• --conf spark.driver.extraClassPath=... or --driver-class-path: These are aliases, doesn't matter which one you choose
• --conf spark.driver.extraLibraryPath=..., or --driver-library-path ... Same as above, aliases.
• --conf spark.executor.extraClassPath=...: Use this when you have a dependency which can't be included in an uber JAR (for example, because there are compile time conflicts between library versions) and which you need to load at runtime.
• --conf spark.executor.extraLibraryPath=... This is passed as the java.library.path option for the JVM. Use this when you need a library path visible to the JVM.

Would it be safe to assume that for simplicity, I can add additional application jar files using the 3 main options at the same time:

You can safely assume this only for Client mode, not Cluster mode. As I've previously said. Also, the example you gave has some redundant arguments. For example, passing JARs to --driver-library-path is useless, you need to pass them to extraClassPath if you want them to be on your classpath. Ultimately, what you want to do when you deploy external JARs on both the driver and the worker is:

spark-submit --jars additional1.jar,additional2.jar \
  --driver-class-path additional1.jar:additional2.jar \
  --conf spark.executor.extraClassPath=additional1.jar:additional2.jar \
  --class MyClass main-application.jar

The latest I have found is that there is a system property called sun.java.launcher.pid that is available at least on linux. My plan is to use that and if it is not found to use the JMX bean.

In the Oracle RDBMS, it is possible to use a multi-row subquery in the select clause as long as the (sub-)output is encapsulated as a collection. In particular, a multi-row select clause subquery can output each of its rows as an xmlelement that is encapsulated in an xmlforest.
