To make everything work, you need to create a config for your server (caddy, nginx) where the main domain will be "docker.for.mac.localhost". For this replace in baseURL "http://localhost/api" on "http://docker.for.mac.localhost/api"

On CentOS 7, the pip version is pip3.4 and is located here:

According to the select_list Oracle select documentation the AS is optional.

As a personal note I think it is easier to read with the AS

In the servlet code, with the instruction request.setAttribute("servletName", categoryList), you save your list in the request object, and use the name "servletName" for refering it.
By the way, using then name "servletName" for a list is quite confusing, maybe it's better call it "list" or something similar: request.setAttribute("list", categoryList)
Anyway, suppose you don't change your serlvet code, and store the list using the name "servletName". When you arrive to your JSP, it's necessary to retrieve the list from the request, and for that you just need the request.getAttribute(...) method.

<%  
// retrieve your list from the request, with casting 
ArrayList<Category> list = (ArrayList<Category>) request.getAttribute("servletName");

// print the information about every category of the list
for(Category category : list) {
    out.println(category.getId());
    out.println(category.getName());
    out.println(category.getMainCategoryId());
}
%>

You're passing link=$a and link=$b in the hrefs for A and B, respectively. They are treated as strings, not variables. The following should fix that for you:

echo '<a href="pass.php?link=' . $a . '">Link 1</a>';

// and

echo '<a href="pass.php?link=' . $b . '">Link 2</a>';

The value of $a also isn't included on pass.php. I would suggest making a common variable file and include it on all necessary pages.

Found solution without @Query (actually I tried which one which is "accepted". However, it didn't work).

Have to return Page<Entity> instead of List<Entity>:

public interface EmployeeRepository 
                          extends PagingAndSortingRepository<Employee, Integer> {
    Page<Employee> findAllByNameIgnoreCaseStartsWith(String name, Pageable pageable);
}

IgnoreCase part was critical for achieving this!

You can use the @NamedEntityGraph annotation to your entity to create a loadable query that set which collections you want to load on your query.

The main advantage of this choice is that hibernate makes one single query to retrieve the entity and its collections and only when you choose to use this graph, like this:

Entity configuration

@Entity
@NamedEntityGraph(name = "graph.myEntity.addresesAndPersons", 
attributeNodes = {
    @NamedAttributeNode(value = "addreses"),
    @NamedAttributeNode(value = "persons"
})

Usage

public MyEntity findNamedGraph(Object id, String namedGraph) {
        EntityGraph<MyEntity> graph = em.getEntityGraph(namedGraph);

        Map<String, Object> properties = new HashMap<>();
        properties.put("javax.persistence.loadgraph", graph);

        return em.find(MyEntity.class, id, properties);
    }

this code works great for me :

echo str_replace(array_keys($data), array_values($data), $query->queryString);

Don't forget to replace $data and $query by your names

Try a different protocol. git:// may have problems from your firewall, for example; try a git clone with https: instead.

Disabled means that no data from that form element will be submitted when the form is submitted. Read-only means any data from within the element will be submitted, but it cannot be changed by the user.

For example:

<input type="text" name="yourname" value="Bob" readonly="readonly" />

This will submit the value "Bob" for the element "yourname".

<input type="text" name="yourname" value="Bob" disabled="disabled" />

This will submit nothing for the element "yourname".

I am using Oracle Database and i had same problem. Eventually i found ORACLE DB is converting all the metadata (table/sp/view/trigger) in upper case.

And i was trying how i wrote table name (myTempTable) in sql whereas it expect how it store table name in databsae (MYTEMPTABLE). Also same applicable on column name.

It is quite common problem with developer whoever used sql and now jumped into ORACLE DB.

Try this

select 
    t.id,
    t.SomeNumt, 
    sum(t.SomeNumt) Over (Order by t.id asc Rows Between Unbounded Preceding and Current Row) as cum
from 
    @t t 
group by
    t.id,
    t.SomeNumt
order by
    t.id asc;

here you can check only y , n if we need to select a name as well that whether this name exists or not.

select name , decode(count(name),0, 'N', 'Y')
  from table
 group by name;

Here when it is Y only then it will return output otherwise it will give null always. Whts ths way to get the records not existing with N like in output we will get Name , N. When name is not existing in table

You may want to distinguish between unset variables and variables that are set and empty:

is_empty() {
    local var_name="$1"
    local var_value="${!var_name}"
    if [[ -v "$var_name" ]]; then
       if [[ -n "$var_value" ]]; then
         echo "set and non-empty"
       else
         echo "set and empty"
       fi
    else
       echo "unset"
    fi
}

str="foo"
empty=""
is_empty str
is_empty empty
is_empty none

Result:

set and non-empty
set and empty
unset

BTW, I recommend using set -u which will cause an error when reading unset variables, this can save you from disasters such as

rm -rf $dir

There are multiple options to implement SSO for a .NET application.

Check out the following tutorials online:

GaryMcAllisterOnline: ASP.NET MVC 4, ADFS 2.0 and 3rd party STS integration (IdentityServer2), Jan 2013

http://garymcallisteronline.blogspot.com/2013/01/aspnet-mvc-4-adfs-20-and-3rd-party-sts.html

The first one uses ASP.NET Web Forms, while the second one uses ASP.NET MVC4.

If your requirements allow you to use a third-party solution, also consider OpenID. There's an open source library called DotNetOpenAuth.

For further information, read MSDN blog post Integrate OpenAuth/OpenID with your existing ASP.NET application using Universal Providers.

Hope this helps!

Just try this:

Bitmap bitmap = BitmapFactory.decodeFile("/path/images/image.jpg");
ByteArrayOutputStream blob = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.PNG, 0 /* Ignored for PNGs */, blob);
byte[] bitmapdata = blob.toByteArray();

If bitmapdata is the byte array then getting Bitmap is done like this:

Bitmap bitmap = BitmapFactory.decodeByteArray(bitmapdata, 0, bitmapdata.length);

Returns the decoded Bitmap, or null if the image could not be decoded.

SQL is the actual language that as defined by the ISO and ANSI. Here is a link to the Wikipedia article. MySQL is a specific implementation of this standard. I believe Oracle bought the company that originally developed MySQL. Other companies also have their own implementations of the SQL standard.

This is a state-of-the-union answer as of Windows PowerShell v5.1 / PowerShell Core v6.2.0:

• Andrew Savinykh's ill-fated answer, despite being the accepted one, is, as of this writing, fundamentally flawed (I do hope it gets fixed - there's enough information in the comments - and in the edit history - to do so).

• Ansgar Wiecher's helpful answer works well, but requires direct use of the .NET Framework (and reads the entire file into memory, though that could be changed). Direct use of the .NET Framework is not a problem per se, but is harder to master for novices and hard to remember in general.

• A future version of PowerShell Core will have a
  Convert-TextFile cmdlet with a -LineEnding parameter to allow in-place updating of text files with a specific newline style, as being discussed on GitHub.

In PSv5+, PowerShell-native solutions are now possible, because Set-Content now supports the -NoNewline switch, which prevents undesired appending of a platform-native newline^[1] :

# Convert CRLFs to LFs only.
# Note:
#  * (...) around Get-Content ensures that $file is read *in full*
#    up front, so that it is possible to write back the transformed content
#    to the same file.
#  * + "`n" ensures that the file has a *trailing LF*, which Unix platforms
#     expect.
((Get-Content $file) -join "`n") + "`n" | Set-Content -NoNewline $file

The above relies on Get-Content's ability to read a text file that uses any combination of CR-only, CRLF, and LF-only newlines line by line.

Caveats:

• You need to specify the output encoding to match the input file's in order to recreate it with the same encoding. The command above does NOT specify an output encoding; to do so, use -Encoding; without -Encoding:

  • In Windows PowerShell, you'll get "ANSI" encoding, your system's single-byte, 8-bit legacy encoding, such as Windows-1252 on US-English systems.
  • In PowerShell Core, you'll get UTF-8 encoding without a BOM.

• The input file's content as well as its transformed copy must fit into memory as a whole, which can be problematic with large input files.

• There's a risk of file corruption, if the process of writing back to the input file gets interrupted.

^{[1] In fact, if there are multiple strings to write, -NoNewline also doesn't place a newline between them; in the case at hand, however, this is irrelevant, because only one string is written.}

1. Add a ToolTip component to your form
2. Select one of the controls that you want a tool tip for
3. Open the property grid (F4), in the list you will find a property called "ToolTip on toolTip1" (or something similar). Set the desired tooltip text on that property.
4. Repeat 2-3 for the other controls
5. Done.

The trick here is that the ToolTip control is an extender control, which means that it will extend the set of properties for other controls on the form. Behind the scenes this is achieved by generating code like in Svetlozar's answer. There are other controls working in the same manner (such as the HelpProvider).

If you want to use the primitive wrapper classes, this will work, but all java types are signed by default.

public static void main(String[] args) {
    Integer i=5;
    Byte b = Byte.valueOf(i+""); //converts i to String and calls Byte.valueOf()
    System.out.println(b);
    System.out.println(Integer.valueOf(b));
}

This can be considered as bit tricky way as in my situation, I can't use a CTE table, so decided to join with sys.all_objects and then created row numbers and added that to start date till it reached the end date.

See the code below where I generated all dates in Jul 2018. Replace hard coded dates with your own variables (tested in SQL Server 2016):

select top (datediff(dd, '2018-06-30', '2018-07-31')) ROW_NUMBER() 
over(order by a.name) as SiNo, 
Dateadd(dd, ROW_NUMBER() over(order by a.name) , '2018-06-30') as Dt from sys.all_objects a

No, you shouldn't do this. Without an ORDER BY clause you shouldn't rely on the order of the results being the same from query to query. It might work nicely during testing but the order is indeterminate and could break later. Use an order by.

SELECT * FROM table1 ORDER BY id LIMIT 5

By the way, another way of getting the last 3 rows is to reverse the order and select the first three rows:

SELECT * FROM table1 ORDER BY id DESC LIMIT 3

This will always work even if the number of rows in the result set isn't always 8.

This condition check

if (!!foo) {
    //foo is defined
}

is all you need.

I nailed it by using sudo port install py27-Pillow

You can use below approach. With this, You don't need to create temp table OR txt/csv file for further select and load respectively.

INSERT INTO TABLE tablename SELECT value1,value2 FROM tempTable_with_atleast_one_records LIMIT 1.

Where tempTable_with_atleast_one_records is any table with atleast one record.

But problem with this approach is that If you have INSERT statement which inserts multiple rows like below one.

INSERT INTO yourTable values (1 , 'value1') , (2 , 'value2') , (3 , 'value3') ;

Then, You need to have separate INSERT hive statement for each rows. See below.

INSERT INTO TABLE yourTable SELECT 1 , 'value1' FROM tempTable_with_atleast_one_records LIMIT 1;
INSERT INTO TABLE yourTable SELECT 2 , 'value2' FROM tempTable_with_atleast_one_records LIMIT 1;
INSERT INTO TABLE yourTable SELECT 3 , 'value3' FROM tempTable_with_atleast_one_records LIMIT 1;

Because of the triviality of the scenario I would actually have the UI thread poll for the status. I think you will find that it can be quite elegant.

public class MyForm : Form
{
  private volatile string m_Text = "";
  private System.Timers.Timer m_Timer;

  private MyForm()
  {
    m_Timer = new System.Timers.Timer();
    m_Timer.SynchronizingObject = this;
    m_Timer.Interval = 1000;
    m_Timer.Elapsed += (s, a) => { MyProgressLabel.Text = m_Text; };
    m_Timer.Start();
    var thread = new Thread(WorkerThread);
    thread.Start();
  }

  private void WorkerThread()
  {
    while (...)
    {
      // Periodically publish progress information.
      m_Text = "Still working...";
    }
  }
}

The approach avoids the marshaling operation required when using the ISynchronizeInvoke.Invoke and ISynchronizeInvoke.BeginInvoke methods. There is nothing wrong with using the marshaling technique, but there are a couple of caveats you need to be aware of.

• Make sure you do not call BeginInvoke too frequently or it could overrun the message pump.
• Calling Invoke on the worker thread is a blocking call. It will temporarily halt the work being done in that thread.

The strategy I propose in this answer reverses the communication roles of the threads. Instead of the worker thread pushing the data the UI thread polls for it. This a common pattern used in many scenarios. Since all you are wanting to do is display progress information from the worker thread then I think you will find that this solution is a great alternative to the marshaling solution. It has the following advantages.

• The UI and worker threads remain loosely coupled as opposed to the Control.Invoke or Control.BeginInvoke approach which tightly couples them.
• The UI thread will not impede the progress of the worker thread.
• The worker thread cannot dominate the time the UI thread spends updating.
• The intervals at which the UI and worker threads perform operations can remain independent.
• The worker thread cannot overrun the UI thread's message pump.
• The UI thread gets to dictate when and how often the UI gets updated.

from two tables with foreign key you can try this Query:

DELETE T1, T2
FROM T1
INNER JOIN T2 ON T1.key = T2.key
WHERE condition

Your count never equals the value 100 so your loop will continue until that is true

Replace your while clause with

def gukan(count):
    while count < 100:
      print(count)
      count=count+3;
gukan(0)

and this will fix your problem, the program is executing correctly given the conditions you have given it.

I have found this to be the easiest way by far.

Use this method:

public static String getJSON(String url) {
        HttpsURLConnection con = null;
        try {
            URL u = new URL(url);
            con = (HttpsURLConnection) u.openConnection();

            con.connect();


            BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));
            StringBuilder sb = new StringBuilder();
            String line;
            while ((line = br.readLine()) != null) {
                sb.append(line + "\n");
            }
            br.close();
            return sb.toString();


        } catch (MalformedURLException ex) {
            ex.printStackTrace();
        } catch (IOException ex) {
            ex.printStackTrace();
        } finally {
            if (con != null) {
                try {
                    con.disconnect();
                } catch (Exception ex) {
                    ex.printStackTrace();
                }
            }
        }
        return null;
    }

And use it like this:

String json = getJSON(url);
JSONObject obj;
   try {
         obj = new JSONObject(json);
         JSONArray results_arr = obj.getJSONArray("results");
         final int n = results_arr.length();
            for (int i = 0; i < n; ++i) {
                // get the place id of each object in JSON (Google Search API)
                String place_id = results_arr.getJSONObject(i).getString("place_id");
            }


   }

This will work with every browser

div {
 -khtml-opacity:.50; 
 -moz-opacity:.50; 
 -ms-filter:"alpha(opacity=50)";
  filter:alpha(opacity=50);
  filter: progid:DXImageTransform.Microsoft.Alpha(opacity=0.5);
  opacity:.50; 
}

If you don't want transparency to affect the entire container and its children, check this workaround. You must have an absolutely positioned child with a relatively positioned parent.

Say this is your xml with spinner entries (ie. titles) and values:

<resources>
    <string-array name="size_entries">
        <item>Small</item>
        <item>Medium</item>
        <item>Large</item>
    </string-array>

    <string-array name="size_values">
        <item>12</item>
        <item>16</item>
        <item>20</item>
    </string-array>
</resources>

and this is your spinner:

<Spinner
    android:id="@+id/size_spinner"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:entries="@array/size_entries" />

Then in your code to get the entries:

Spinner spinner = (Spinner) findViewById(R.id.size_spinner);
String size = spinner.getSelectedItem().toString(); // Small, Medium, Large

and to get the values:

int spinner_pos = spinner.getSelectedItemPosition();
String[] size_values = getResources().getStringArray(R.array.size_values);
int size = Integer.valueOf(size_values[spinner_pos]); // 12, 16, 20

For understanding templates, it's of huge advantage to get the terminology straight because the way you speak about them determines the way to think about them.

Specifically, Area is not a template class, but a class template. That is, it is a template from which classes can be generated. Area<int> is such a class (it's not an object, but of course you can create an object from that class in the same ways you can create objects from any other class). Another such class would be Area<char>. Note that those are completely different classes, which have nothing in common except for the fact that they were generated from the same class template.

Since Area is not a class, you cannot derive the class Rectangle from it. You only can derive a class from another class (or several of them). Since Area<int> is a class, you could, for example, derive Rectangle from it:

class Rectangle:
  public Area<int>
{
  // ...
};

Since Area<int> and Area<char> are different classes, you can even derive from both at the same time (however when accessing members of them, you'll have to deal with ambiguities):

class Rectangle:
  public Area<int>,
  public Area<char>
{
  // ...
};

However you have to specify which classed to derive from when you define Rectangle. This is true no matter whether those classes are generated from a template or not. Two objects of the same class simply cannot have different inheritance hierarchies.

What you can do is to make Rectangle a template as well. If you write

template<typename T> class Rectangle:
  public Area<T>
{
  // ...
};

You have a template Rectangle from which you can get a class Rectangle<int> which derives from Area<int>, and a different class Rectangle<char> which derives from Area<char>.

It may be that you want to have a single type Rectangle so that you can pass all sorts of Rectangle to the same function (which itself doesn't need to know the Area type). Since the Rectangle<T> classes generated by instantiating the template Rectangle are formally independent of each other, it doesn't work that way. However you can make use of multiple inheritance here:

class Rectangle // not inheriting from any Area type
{
  // Area independent interface
};

template<typename T> class SpecificRectangle:
  public Rectangle,
  public Area<T>
{
  // Area dependent stuff
};

void foo(Rectangle&); // A function which works with generic rectangles

int main()
{
  SpecificRectangle<int> intrect;
  foo(intrect);

  SpecificRectangle<char> charrect;
  foo(charrect);
}

If it is important that your generic Rectangle is derived from a generic Area you can do the same trick with Area too:

class Area
{
  // generic Area interface
};

class Rectangle:
  public virtual Area // virtual because of "diamond inheritance"
{
  // generic rectangle interface
};

template<typename T> class SpecificArea:
  public virtual Area
{
  // specific implementation of Area for type T
};

template<typename T> class SpecificRectangle:
  public Rectangle, // maybe this should be virtual as well, in case the hierarchy is extended later
  public SpecificArea<T> // no virtual inheritance needed here
{
  // specific implementation of Rectangle for type T
};

Lots of good answers here, here's my addition along with several unit tests that can be used to help test correctness, my solution is similar to @Rianne's above but uses an ISet to provide O(1) lookup time on the replacement characters (and also similar to @Albin Sunnanbo's Linq solution).

    using System;
    using System.Collections.Generic;
    using System.Linq;

    /// <summary>
    /// Returns a string with the specified characters removed.
    /// </summary>
    /// <param name="source">The string to filter.</param>
    /// <param name="removeCharacters">The characters to remove.</param>
    /// <returns>A new <see cref="System.String"/> with the specified characters removed.</returns>
    public static string Remove(this string source, IEnumerable<char> removeCharacters)
    {
        if (source == null)
        {
            throw new  ArgumentNullException("source");
        }

        if (removeCharacters == null)
        {
            throw new ArgumentNullException("removeCharacters");
        }

        // First see if we were given a collection that supports ISet
        ISet<char> replaceChars = removeCharacters as ISet<char>;

        if (replaceChars == null)
        {
            replaceChars = new HashSet<char>(removeCharacters);
        }

        IEnumerable<char> filtered = source.Where(currentChar => !replaceChars.Contains(currentChar));

        return new string(filtered.ToArray());
    }

You can simply do the following :

$fi = new FilesystemIterator(__DIR__, FilesystemIterator::SKIP_DOTS);
printf("There were %d Files", iterator_count($fi));

$('#navigation ul li').css({'display' : 'inline-block'});

It seems a typo there ...syntax mistake :))

The possibility could be, the SSH might not be enabled on your server/system.

1. Check sudo systemctl status ssh is Active or not.
2. If it's not active, try installing with the help of these commands

sudo apt update

sudo apt install openssh-server

Now try to access the server/system with following command

ssh username@ip_address

OpenSSL has a horrible documentation with no code examples, but here you are:

#include <openssl/sha.h>

bool simpleSHA256(void* input, unsigned long length, unsigned char* md)
{
    SHA256_CTX context;
    if(!SHA256_Init(&context))
        return false;

    if(!SHA256_Update(&context, (unsigned char*)input, length))
        return false;

    if(!SHA256_Final(md, &context))
        return false;

    return true;
}

Usage:

unsigned char md[SHA256_DIGEST_LENGTH]; // 32 bytes
if(!simpleSHA256(<data buffer>, <data length>, md))
{
    // handle error
}

Afterwards, md will contain the binary SHA-256 message digest. Similar code can be used for the other SHA family members, just replace "256" in the code.

If you have larger data, you of course should feed data chunks as they arrive (multiple SHA256_Update calls).

How about building a Queue with the elements you want to iterate over; when you want to add elements, enqueue them at the end of the queue, and keep removing elements until the queue is empty. This is how a breadth-first search usually works.

Just a minor point; put the following in the header

using namespace std;

then

std::cout << std::fixed << std::setprecision(2) << d;

becomes simplified to

cout << fixed << setprecision(2) << d;

Assume a network environment where a "user" (aka you) has to logon. Usually this is a User ID (UID) and a Password (PW). OK then, what is your Identity, or who are you? You are the UID, and this gleans that "name" from your logon session. Simple! It should also work in an internet application that needs you to login, like Best Buy and others.

This will pull my UID, or "Name", from my session when I open the default page of the web application I need to use. Now, in my instance, I am part of a Domain, so I can use initial Windows authentication, and it needs to verify who I am, thus the 2nd part of the code. As for Forms Authentication, it would rely on the ticket (aka cookie most likely) sent to your workstation/computer. And the code would look like:

string id = HttpContext.Current.User.Identity.Name;

// Strip the domain off of the result
id = id.Substring(id.LastIndexOf(@"\", StringComparison.InvariantCulture) + 1);

Now it has my business name (aka UID) and can display it on the screen.

I believe the sprintf is the right function for you. I's in the standard library, like printf. Follow the link below for more information:

Ask your DBA about auditing. He can start an audit with a simple command like :

AUDIT INSERT ON user.table

Then you can query the table USER_AUDIT_OBJECT to determine if there has been an insert on your table since the last export.

google for Oracle auditing for more info...

There are also some properties you can set to force a control to fill its available space when it would otherwise not do so. For example, you can say:

HorizontalContentAlignment="Stretch"

... to force the contents of a control to stretch horizontally. Or you can say:

HorizontalAlignment="Stretch"

... to force the control itself to stretch horizontally to fill its parent.

As others have said you are "tainting" the canvas by loading from a cross origins domain.

https://developer.mozilla.org/en-US/docs/HTML/CORS_Enabled_Image

However, you may be able to prevent this by simply setting:

img.crossOrigin = "Anonymous";

This only works if the remote server sets the following header appropriately:

Access-Control-Allow-Origin "*"

The Dropbox file chooser when using the "direct link" option is a great example of this. I use it on oddprints.com to hoover up images from the remote dropbox image url, into my canvas, and then submit the image data back into my server. All in javascript

I am using this function for describe table.

If you have a ConstraintLayout with some size, and a child View with some smaller size, you can achieve centering by constraining the child's two edges to the same two edges of the parent. That is, you can write:

app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"

or

app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"

Because the view is smaller, these constraints are impossible. But ConstraintLayout will do the best it can, and each constraint will "pull" at the child view equally, thereby centering it.

This concept works with any target view, not just the parent.

Below is XML that achieves your desired UI with no nesting of views and no Guidelines (though guidelines are not inherently evil).

To get all values of all sections from appsettings.json

        public static string[] Sections = { "LogDirectory", "Application", "Email" };
        Dictionary<string, string> sectionDictionary = new Dictionary<string, string>();

        List<string> sectionNames = new List<string>(Sections);
        
        sectionNames.ForEach(section =>
        {
            List<KeyValuePair<string, string>> sectionValues = configuration.GetSection(section)
                    .AsEnumerable()
                    .Where(p => p.Value != null)
                    .ToList();
            foreach (var subSection in sectionValues)
            {
                sectionDictionary.Add(subSection.Key, subSection.Value);
            }
        });
        return sectionDictionary;

While yourTextField.requestFocus() is A solution, it is not the best since in the official Java documentation this is discourage as the method requestFocus() is platform dependent.

The documentation says:

Note that the use of this method is discouraged because its behavior is platform dependent. Instead we recommend the use of requestFocusInWindow().

Use yourJTextField.requestFocusInWindow() instead.

For PHP, Java, C++, C, Perl, JavaScript, CSS you can try:

http://www.prettyprinter.de/index.php

Try this,

1.Rename your index.html to “main.html”

2.Create a new “index.html” and put the following content into it:

<!doctype html>
<html>
  <head>
   <title>tittle</title>
   <script>
     window.location='./main.html';
   </script>
  <body>
  </body>
</html>

3.Rebuild your app! No more errors!

This is an elegant solution that I quite appreciate because it uses zero data bytes:

some_flag CHAR(0) DEFAULT NULL

To set it to true, set some_flag = '' and to set it to false, set some_flag = NULL.

Then to test for true, check if some_flag IS NOT NULL, and to test for false, check if some_flag IS NULL.

(This method is described in "High Performance MySQL: Optimization, Backups, Replication, and More" by Jon Warren Lentz, Baron Schwartz and Arjen Lentz.)

srand doesn't return anything so you can't initialize a with its return value because, well, because it doesn't return a value. Did you mean to call rand as well?

Just to expand on @DRAX's answer, I'd do this:

function isWhitespaceEmptyString(str)
{
    //RETURN:
    //      = 'true' if 'str' is empty string, null, undefined, or consists of white-spaces only
    return str ? !(/\S/.test(str)) : (str === "" || str === null || str === undefined);
}

It will account also for nulls and undefined types, and it will take care of non-string types, such as 0.

If you are mocking the behavior (with something like doNothing()) there should really be no need to call to verify*(). That said, here's my stab at re-writing your test method:

@PrepareForTest({InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest { //Note the renaming of the test class.
   public void testProcessOrder() {
        //Variables
        InternalService is = new InternalService();
        Order order = mock(Order.class);

        //Mock Behavior
        when(order.isSuccessful()).thenReturn(true);
        mockStatic(Internalutils.class);
        doNothing().when(InternalUtils.class); //This is the preferred way
                                               //to mock static void methods.
        InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());

        //Execute
        is.processOrder(order);            

        //Verify
        verifyStatic(InternalUtils.class); //Similar to how you mock static methods
                                           //this is how you verify them.
        InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());
   }
}

I grouped into four sections to better highlight what is going on:

1. Variables

I choose to declare any instance variables / method arguments / mock collaborators here. If it is something used in multiple tests, consider making it an instance variable of the test class.

2. Mock Behavior

This is where you define the behavior of all of your mocks. You're setting up return values and expectations here, prior to executing the code under test. Generally speaking, if you set the mock behavior here you wouldn't need to verify the behavior later.

3. Execute

Nothing fancy here; this just kicks off the code being tested. I like to give it its own section to call attention to it.

4. Verify

This is when you call any method starting with verify or assert. After the test is over, you check that the things you wanted to have happen actually did happen. That is the biggest mistake I see with your test method; you attempted to verify the method call before it was ever given a chance to run. Second to that is you never specified which static method you wanted to verify.

Additional Notes

This is mostly personal preference on my part. There is a certain order you need to do things in but within each grouping there is a little wiggle room. This helps me quickly separate out what is happening where.

I also highly recommend going through the examples at the following sites as they are very robust and can help with the majority of the cases you'll need:

• https://github.com/powermock/powermock/wiki/Mockito (PowerMock Overview / Examples)
• http://site.mockito.org/mockito/docs/current/org/mockito/Mockito.html (Mockito Overview / Examples)

The downside of NULL in C++ is that it is a define for 0. This is a value that can be silently converted to pointer, a bool value, a float/double, or an int.

That is not very type safe and has lead to actual bugs in an application I worked on.

Consider this:

void Foo(int i);
void Foo(Bar* b);
void Foo(bool b);


main()
{
     Foo(0);         
     Foo(NULL); // same as Foo(0)
} 

C++11 defines a nullptr that is convertible to a null pointer but not to other scalars. This is supported in all modern C++ compilers, including VC++ as of 2008. In older versions of GCC there is a similar feature, but then it was called __null.

I followed the below Steps. It worked for me.

In Jenkins execute shell under Build, creating a file and trying to push that file from Jenkins workspace to GitHub.

Download Git Publisher Plugin and Configure as shown below snapshot.

Click on Save and Build. Now you can check your git repository whether the file was pushed successfully or not.

If you have password for your dB then

mysql -u <username> -p <DBName> < yourfile.sql

Here's a complete example of how it can be done. However you need flashback query privileges on the child table.

Here's the setup.

create table parent_tab
  (parent_id number primary key,
  val varchar2(20));

create table child_tab
    (child_id number primary key,
    parent_id number,
    child_val number,
     constraint child_par_fk foreign key (parent_id) references parent_tab);

insert into parent_tab values (1,'Red');
insert into parent_tab values (2,'Green');
insert into parent_tab values (3,'Blue');
insert into parent_tab values (4,'Black');
insert into parent_tab values (5,'White');

insert into child_tab values (10,1,100);
insert into child_tab values (20,3,100);
insert into child_tab values (30,3,100);
insert into child_tab values (40,4,100);
insert into child_tab values (50,5,200);

commit;

select * from parent_tab
where parent_id not in (select parent_id from child_tab);

Now delete a subset of the children (ones with parents 1,3 and 4 - but not 5).

delete from child_tab where child_val = 100;

Then get the parent_ids from the current COMMITTED state of the child_tab (ie as they were prior to your deletes) and remove those that your session has NOT deleted. That gives you the subset that have been deleted. You can then delete those out of the parent_tab

delete from parent_tab
where parent_id in
  (select parent_id from child_tab as of scn dbms_flashback.get_system_change_number
  minus
  select parent_id from child_tab);

'Green' is still there (as it didn't have an entry in the child table anyway) and 'Red' is still there (as it still has an entry in the child table)

select * from parent_tab
where parent_id not in (select parent_id from child_tab);

select * from parent_tab;

It is an exotic/unusual operation, so if i was doing it I'd probably be a bit cautious and lock both child and parent tables in exclusive mode at the start of the transaction. Also, if the child table was big it wouldn't be particularly performant so I'd opt for a PL/SQL solution like Rajesh's.

You can get the spark version by using the following command:

spark-submit --version

spark-shell --version

spark-sql --version

You can visit the below site to know the spark-version used in CDH 5.7.0

There isn't a magic bullet solution for what you're looking for, unfortunately. Here's what you can do:

• create an Interface class using this command in the Visual Studio Command Prompt window:

  wsdl.exe yourFile.wsdl /l:CS /serverInterface
  Use VB or CS for your language of choice. This will create a new .cs or .vb file.

• Create a new .NET Web Service project. Import Existing File into your project - the file that was created in the step above.

• In your .asmx.cs file in Code-View, modify your class as such:

 public class MyWebService : System.Web.Services.WebService, IMyWsdlInterface
 {    
     [WebMethod]
     public string GetSomeString()
     {
         //you'll have to write your own business logic 
         return "Hello SOAP World";
     }
 }

u just used attribute

• android:background="#ColorCode" for colors

  if your image save in drawable folder then used :-

• android:background="@drawable/ImageName" for image setting

here is a portion of a procedure I use on my system to find text....

DECLARE @Search varchar(255)
SET @Search='[10.10.100.50]'

SELECT DISTINCT
    o.name AS Object_Name,o.type_desc
    FROM sys.sql_modules        m 
        INNER JOIN sys.objects  o ON m.object_id=o.object_id
    WHERE m.definition Like '%'+@Search+'%'
    ORDER BY 2,1

There is a big difference. Tasks are scheduled on the ThreadPool and could even be executed synchronous if appropiate.

If you have a long running background work you should specify this by using the correct Task Option.

You should prefer Task Parallel Library over explicit thread handling, as it is more optimized. Also you have more features like Continuation.

The basic difference between interface and abstract class is, interface supports multiple inheritance but abstract class not.

In abstract class also you can provide all abstract methods like interface.

why abstract class is required?

In some scenarios, while processing user request, the abstract class doesn't know what user intention. In that scenario, we will define one abstract method in the class and ask the user who extending this class, please provide your intention in the abstract method. In this case abstract classes are very useful

Why interface is required?

Let's say, I have a work which I don't have experience in that area. Example, if you want to construct a building or dam, then what you will do in that scenario?

1. you will identify what are your requirements and make a contract with that requirements.
2. Then call the Tenders to construct your project
3. Who ever construct the project, that should satisfy your requirements. But the construction logic is different from one vendor to other vendor.

Here I don't bother about the logic how they constructed. The final object satisfied my requirements or not, that only my key point.

Here your requirements called interface and constructors are called implementor.

The way to do this is via the bracket notation.

var test = {_x000D_
    "id": "109",_x000D_
    "No. of interfaces": "4"_x000D_
}_x000D_
alert(test["No. of interfaces"]);

onCreate() method gets called when activity gets created, and its called only once in whole Activity life cycle. where as onStart() is called when activity is stopped... I mean it has gone to background and its onStop() method is called by the os. onStart() may be called multiple times in Activity life cycle.More details here

Another way to go about it, besides the nice answers already mentioned, depends upon the fact that you can pass optional named arguments by position. For example,

def f(x,y=None):
    print(x)
    if y is not None:
        print(y)

Yields

In [11]: f(1,2)
1
2

In [12]: f(1)
1

Since PHP 5.5, you can use array_column:

$ids = array_column($users, 'id');

This is the preferred option on any modern project. However, if you must support PHP<5.5, the following alternatives exist:

Since PHP 5.3, you can use array_map with an anonymous function, like this:

$ids = array_map(function ($ar) {return $ar['id'];}, $users);

Before ^{_{(Technically PHP 4.0.6+)}}, you must create an anonymous function with create_function instead:

$ids = array_map(create_function('$ar', 'return $ar["id"];'), $users);

This might help //Printing The Array

for (int i = 0; i < n; i++)
{cout << numbers[i];}

n is the size of the array

Changing text color of button

Because this method is now deprecated

button.setTextColor(getResources().getColor(R.color.your_color));

I use the following:

button.setTextColor(ContextCompat.getColor(mContext, R.color.your_color));

Just modify one of the returned entities:

Customer c = (from x in dataBase.Customers
             where x.Name == "Test"
             select x).First();
c.Name = "New Name";
dataBase.SaveChanges();

Note, you can only update an entity (something that extends EntityObject, not something that you have projected using something like select new CustomObject{Name = x.Name}

In my case I was trying to create my dialog like this:

new Dialog(getApplicationContext());

So I had to change for:

new Dialog(this);

And it works fine for me ;)

CharField has max_length of 255 characters while TextField can hold more than 255 characters. Use TextField when you have a large string as input. It is good to know that when the max_length parameter is passed into a TextField it passes the length validation to the TextArea widget.

I could achieve a button using jQueryMobile with following code:

<label for="ppt" data-role="button" data-inline="true" data-mini="true" data-corners="false">Upload</label>
<input id="ppt" type="file" name="ppt" multiple data-role="button" data-inline="true" data-mini="true" data-corners="false" style="opacity: 0;"/>

Above code creates a "Upload" button (custom text). On click of upload button, file browse is launched. Tested with Chrome 25 & IE9.

well this is simple one to show back button

actionBar.setDisplayHomeAsUpEnabled(true);

and then you can custom the back event at onOptionsItemSelected

case android.R.id.home:
this.finish();
return true;

Right now (as of 2008), all the SOAP libraries available for Python suck. I recommend avoiding SOAP if possible. The last time we where forced to use a SOAP web service from Python, we wrote a wrapper in C# that handled the SOAP on one side and spoke COM out the other.

EDIT 2017-04-29: As pointed to by some of the commenters, the JoinTable example does not need the mappedBy annotation attribute. In fact, recent versions of Hibernate refuse to start up by printing the following error:

org.hibernate.AnnotationException: 
   Associations marked as mappedBy must not define database mappings 
   like @JoinTable or @JoinColumn

Let's pretend that you have an entity named Project and another entity named Task and each project can have many tasks.

You can design the database schema for this scenario in two ways.

The first solution is to create a table named Project and another table named Task and add a foreign key column to the task table named project_id:

Project      Task
-------      ----
id           id
name         name
             project_id

This way, it will be possible to determine the project for each row in the task table. If you use this approach, in your entity classes you won't need a join table:

@Entity
public class Project {

   @OneToMany(mappedBy = "project")
   private Collection<Task> tasks;

}

@Entity
public class Task {

   @ManyToOne
   private Project project;

}

The other solution is to use a third table, e.g. Project_Tasks, and store the relationship between projects and tasks in that table:

Project      Task      Project_Tasks
-------      ----      -------------
id           id        project_id
name         name      task_id

The Project_Tasks table is called a "Join Table". To implement this second solution in JPA you need to use the @JoinTable annotation. For example, in order to implement a uni-directional one-to-many association, we can define our entities as such:

Project entity:

@Entity
public class Project {

    @Id
    @GeneratedValue
    private Long pid;

    private String name;

    @JoinTable
    @OneToMany
    private List<Task> tasks;

    public Long getPid() {
        return pid;
    }

    public void setPid(Long pid) {
        this.pid = pid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public List<Task> getTasks() {
        return tasks;
    }

    public void setTasks(List<Task> tasks) {
        this.tasks = tasks;
    }
}

Task entity:

@Entity
public class Task {

    @Id
    @GeneratedValue
    private Long tid;

    private String name;

    public Long getTid() {
        return tid;
    }

    public void setTid(Long tid) {
        this.tid = tid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

This will create the following database structure:

The @JoinTable annotation also lets you customize various aspects of the join table. For example, had we annotated the tasks property like this:

@JoinTable(
        name = "MY_JT",
        joinColumns = @JoinColumn(
                name = "PROJ_ID",
                referencedColumnName = "PID"
        ),
        inverseJoinColumns = @JoinColumn(
                name = "TASK_ID",
                referencedColumnName = "TID"
        )
)
@OneToMany
private List<Task> tasks;

The resulting database would have become:

Finally, if you want to create a schema for a many-to-many association, using a join table is the only available solution.

This would be a good candidate for MetaWhere if you're using Rails 3.0+, but it doesn't work on Rails 3.1. You might want to try out squeel instead. It's made by the same author. Here's how'd you'd perform an OR based chain:

Person.where{(name == "John") | (lastname == "Smith")}

You can mix and match AND/OR, among many other awesome things.

How to import a commons-library into netbeans.

1. Evaluate the error message in NetBeans:

   java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
   

2. NoClassDeffFoundError means somewhere under the hood in the code you used, a method called another method which invoked a class that cannot be found. So what that means is your code did this: MyFoobarClass foobar = new MyFoobarClass() and the compiler is confused because nowhere is defined this MyFoobarClass. This is why you get an error.

3. To know what to do next, you have to look at the error message closely. The words 'org/apache/commons' lets you know that this is the codebase that provides the tools you need. You have a choice, either you can import EVERYTHING in apache commons, or you could import JUST the LogFactory class, or you could do something in between. Like for example just get the logging bit of apache commons.

4. You'll want to go the middle of the road and get commons-logging. Excellent choice, fire up the google and search for apache commons-logging. The first link takes you to http://commons.apache.org/proper/commons-logging/. Go to downloads. There you will find the most up-to-date ones. If your project was compiled under ancient versions of commons-logging, then use those same ancient ones because if you use the newer ones, the code may fail because the newer versions are different.

5. You're going to want to download the commons-logging-1.1.3-bin.zip or something to that effect. Read what the name is saying. The .zip means it's a compressed file. commons-logging means that this one should contain the LogFactory class you desire. the middle 1.1.3 means that is the version. if you are compiling for an old version, you'll need to match these up, or else you risk the code not compiling right due to changes due to upgrading.

6. Download that zip. Unzip it. Search around for things that end in .jar. In netbeans right click your project, click properties, click libraries, click "add jar/folder" and import those jars. Save the project, and re-run, and the errors should be gone.

The binaries don't include the source code, so you won't be able to drill down and see what is happening when you debug. As programmers you should be downloading "the source" of apache commons and compiling from source, generating the jars yourself and importing those for experience. You should be smart enough to understand and correct the source code you are importing. These ancient versions of apache commons might have been compiled under an older version of Java, so if you go too far back, they may not even compile unless you compile them under an ancient version of java.

@AlexCuse I wanted to add this as comment to your answer but gave up after making multiple failed attempt to add newlines in comments.

That said, t1ID is unique in table_1 but that doesn't makes it unique in INFO table as well.

For example:

Table_1 has:
Id Field
1 A
2 B

Table_2 has:
Id Field
1 X
2 Y

INFO then can have:
t1ID t2ID field
1 1 some
1 2 data
2 1 in-each
2 2 row

So in INFO table to uniquely identify a row you need both t1ID and t2ID

Although this shouldn't be a bottle neck as branching issues on modern processors isn't normally a problem, but in the case of integers you could go for a branch-less solution as outlined here: http://graphics.stanford.edu/~seander/bithacks.html#IntegerAbs.

(x + (x >> 31)) ^ (x >> 31);

This does fail in the obvious case of Integer.MIN_VALUE however, so this is a use at your own risk solution.

The accepted answer is good enough.But my solution is more simple.I just test in Linux, use gcc (Ubuntu 7.2.0-8ubuntu3.2) 7.2.0.

Alse use gettimeofday, the tv_sec is the part of second, and the tv_usec is microseconds, not milliseconds.

long currentTimeMillis() {
  struct timeval time;
  gettimeofday(&time, NULL);

  return time.tv_sec * 1000 + time.tv_usec / 1000;
}

int main() {
  printf("%ld\n", currentTimeMillis());
  // wait 1 second
  sleep(1);
  printf("%ld\n", currentTimeMillis());
  return 0;
 }

It print:

1522139691342
1522139692342, exactly a second.
^

I found this problem too. Because centos service depend on multi-user.target for none desktop Cenots 7.2. so I delete multi-user.target from my .service file. It had missed.

Prevent Default

Calling preventDefault() during any stage of event flow cancels the event, meaning that any default action normally taken by the implementation as a result of the event will not occur. You can use Event.

return false

return false inside a callback prevents the default behaviour. For example, in a submit event, it doesn't submit the form. return false also stops bubbling, so the parents of the element won't know the event occurred. return false is equivalent to event.preventDefault() + event.stopPropagation()

Many firewalls drop outbound connections which are not to ports 80 or 443 (http & https); some even drop connections to those ports that are not HTTP(S). FTP may or may not be allowed, not to speak of the active/PASV modes.

Also, HTTP/1.1 allows for much better partial requests ("only send from byte 123456 to the end of file"), conditional requests and caching ("only send if content changed/if last-modified-date changed") and content compression (gzip).

HTTP is much easier to use through a proxy.

From my anecdotal evidence, HTTP is easier to make work with dropped/slow/flaky connections; e.g. it is not needed to (re)establish a login session before (re)initiating transfer.

OTOH, HTTP is stateless, so you'd have to do authentication and building a trail of "who did what when" yourself.

The only difference in speed I've noticed is transferring lots of small files: HTTP with pipelining is faster (reduces round-trips, esp. noticeable on high-latency networks).

Note that HTTP/2 offers even more optimizations, whereas the FTP protocol has not seen any updates for decades (and even extensions to FTP have insignificant uptake by users). So, unless you are transferring files through a time machine, HTTP seems to have won.

(Tangentially: there are protocols that are better suited for file transfer, such as rsync or BitTorrent, but those don't have as much mindshare, whereas HTTP is Everywhere™)

Did you set the section header height in the viewDidLoad?

self.tableView.sectionHeaderHeight = 70

Plus you should replace

self.view.addSubview(view)

by

view.addSubview(label)

Finally you have to check your frames

let view = UIView(frame: CGRect.zeroRect)

and eventually the desired text color as it seems to be currently white on white.

'<option value=''.$key.'">'

should be

'<option value="'.$key.'">'

Looking at the documentation for JSON, it seems that the regex can simply be three parts if the goal is just to check for fitness:

1. The string starts and ends with either [] or {}
   • [{\[]{1}...[}\]]{1}
2. and
   1. The character is an allowed JSON control character (just one)
      • ...[,:{}\[\]0-9.\-+Eaeflnr-u \n\r\t]...
   2. or The set of characters contained in a ""
      • ...".*?"...

All together: [{\[]{1}([,:{}\[\]0-9.\-+Eaeflnr-u \n\r\t]|".*?")+[}\]]{1}

If the JSON string contains newline characters, then you should use the singleline switch on your regex flavor so that . matches newline. Please note that this will not fail on all bad JSON, but it will fail if the basic JSON structure is invalid, which is a straight-forward way to do a basic sanity validation before passing it to a parser.

Keep it simple

dataGridView1.Columns.Add("newColumnName", "Column Name in Text");

To add rows

dataGridView1.Rows.Add("Value for column#1"); // [,"column 2",...]

Use the not function instead:

var lastOpenSite = $(this).siblings().not('.closedTab');

hasClass only tests whether an element has a class, not will remove elements from the selected set matching the provided selector.

if you have a dataframe where some columns are numeric and some are other (character or factor) and you only want to do the correlations for the numeric columns, you could do the following:

x$L1 = letters[1:10]
x$L2 = letters[11:20]

cor(x)

If using Python 2.7 or higher (especially prior to Python 3.5) you can use the following:

import subprocess

• subprocess.call(args, *, stdin=None, stdout=None, stderr=None, shell=False) Runs the command described by args. Waits for command to complete, then returns the returncode attribute.
• subprocess.check_call(args, *, stdin=None, stdout=None, stderr=None, shell=False) Runs command with arguments. Waits for command to complete. If the return code was zero then returns, otherwise raises CalledProcessError. The CalledProcessError object will have the return code in the returncode attribute

Example: subprocess.check_call([r"C:\pathToYourProgram\yourProgram.exe", "your", "arguments", "comma", "separated"])

In regular Python strings, the \U character combination signals a extended Unicode code point escape.

Here is the link to the documentation: http://docs.python.org/3.2/library/subprocess.html

For Python 3.5+ you can now use run() in many cases: https://docs.python.org/3.5/library/subprocess.html#subprocess.run

Short answer, unpacking tuples from a list in a for loop works. enumerate() creates a tuple using the current index and the entire current item, such as (0, ('bob', 3))

I created some test code to demonstrate this:

    list = [('bob', 3), ('alice', 0), ('john', 5), ('chris', 4), ('alex', 2)]

    print("Displaying Enumerated List")
    for name, num in enumerate(list):
        print("{0}: {1}".format(name, num))

    print("Display Normal Iteration though List")
    for name, num in list:
        print("{0}: {1}".format(name, num))

The simplicity of Tuple unpacking is probably one of my favourite things about Python :D

In your 'test' directive Html tag, the attribute name of the function should not be camelCased, but dash-based.

so - instead of :

<test color1="color1" updateFn="updateFn()"></test>

write:

<test color1="color1" update-fn="updateFn()"></test>

This is angular's way to tell the difference between directive attributes (such as update-fn function) and functions.

The connector section has the parameter

maxPostSize

The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes).

Another Limit is:

maxHttpHeaderSize The maximum size of the request and response HTTP header, specified in bytes. If not specified, this attribute is set to 4096 (4 KB).

You find them in

$TOMCAT_HOME/conf/server.xml

        <table id="table_id" class="table table-hover">
          <thead>
            <tr>
             ...
             ...
            </tr>
          </thead>
        </table>

use this command to clear the body of that table: $("#table_id tbody").empty()

I use jquery to load the table content dynamically, and use this command to clear the body when doing the refreshing.

hope this helps you.

I do also have a huge masochistic streak as that I've written yet another JSON parser. This one uses a procedural approach. It uses a similat SQL hierarchy list table to store the parsed data. Also in the package are:

• Reverse process: from hierarchy to JSON
• Querying functions: to fetch particular values from a JSON object

Please feel free to use and have fun with it

An extract from my blog post on coupling:

What is Tight Coupling:-

As par above definition a Tightly Coupled Object is an object that needs to know about other objects and are usually highly dependent on each other's interfaces.

When we change one object in a tightly coupled application often it requires changes to a number of other objects. There is no problem in a small application we can easily identify the change. But in the case of a large applications these inter-dependencies are not always known by every consumer or other developers or there is many chance of future changes.

Let’s take a shopping cart demo code to understand the tight coupling:

namespace DNSLooseCoupling
{
    public class ShoppingCart
    {
        public float Price;
        public int Quantity;

        public float GetRowItemTotal()
        {
            return Price * Quantity;
        }
    }

    public class ShoppingCartContents
    {
        public ShoppingCart[] items;

        public float GetCartItemsTotal()
        {
            float cartTotal = 0;
            foreach (ShoppingCart item in items)
            {
                cartTotal += item.GetRowItemTotal();
            }
            return cartTotal;
        }
    }

    public class Order
    {
        private ShoppingCartContents cart;
        private float salesTax;

        public Order(ShoppingCartContents cart, float salesTax)
        {
            this.cart = cart;
            this.salesTax = salesTax;
        }

        public float OrderTotal()
        {
            return cart.GetCartItemsTotal() * (2.0f + salesTax);
        }
    }
}

Problems with the above example

Tight Coupling creates some difficulties.

Here, OrderTotal() methods is give us complete amount for the current items of the carts. If we want to add the discount features in this cart system. It is very hard to do in above code because we have to make changes at every class as it is very tightly coupled.

Basically I use Fiddler or Postman for testing API's.

In fiddler, in request header you need to specify instead of xml, html you need to change it to json. Eg: Accept: application/json. That should do the job.

Assuming you are already in the directory, and that the "first 8 characters" from your comment hold true always. (Although "CHEESE_" is 7 characters... ? If so, change the 8 below to 7)

from glob import glob
from os import rename
for fname in glob('*.prj'):
    rename(fname, fname[8:])

You have to add

<script>jQuery.noConflict();</script>

after

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>

You can go to LESS CSS website http://lesscss.org/

Their dockable menu is light and performs well. The only caveat is that the effect takes place after the scroll is complete. Just do a view source to see the js.

Update Sept. 2016: Docker 1.13: PR 26108 and commit 86de7c0 introduce a few new commands to help facilitate visualizing how much space the docker daemon data is taking on disk and allowing for easily cleaning up "unneeded" excess.

docker system prune will delete ALL dangling data (i.e. In order: containers stopped, volumes without containers and images with no containers). Even unused data, with -a option.

You also have:

• docker container prune
• docker image prune
• docker network prune
• docker volume prune

For unused images, use docker image prune -a (for removing dangling and ununsed images).
Warning: 'unused' means "images not referenced by any container": be careful before using -a.

As illustrated in A L's answer, docker system prune --all will remove all unused images not just dangling ones... which can be a bit too much.

Combining docker xxx prune with the --filter option can be a great way to limit the pruning (docker SDK API 1.28 minimum, so docker 17.04+)

The currently supported filters are:

• until (<timestamp>) - only remove containers, images, and networks created before given timestamp
• label (label=<key>, label=<key>=<value>, label!=<key>, or label!=<key>=<value>) - only remove containers, images, networks, and volumes with (or without, in case label!=... is used) the specified labels.

See "Prune images" for an example.

Original answer (Sep. 2016)

I usually do:

docker rmi $(docker images --filter "dangling=true" -q --no-trunc)

I have an alias for removing those [dangling images]13: drmi

The dangling=true filter finds unused images

That way, any intermediate image no longer referenced by a labelled image is removed.

I do the same first for exited processes (containers)

alias drmae='docker rm $(docker ps -qa --no-trunc --filter "status=exited")'

As haridsv points out in the comments:

Technically, you should first clean up containers before cleaning up images, as this will catch more dangling images and less errors.

Jess Frazelle (jfrazelle) has the bashrc function:

dcleanup(){
    docker rm -v $(docker ps --filter status=exited -q 2>/dev/null) 2>/dev/null
    docker rmi $(docker images --filter dangling=true -q 2>/dev/null) 2>/dev/null
}

To remove old images, and not just "unreferenced-dangling" images, you can consider docker-gc:

A simple Docker container and image garbage collection script.

• Containers that exited more than an hour ago are removed.
• Images that don't belong to any remaining container after that are removed.

In a Python interpreter or script, you can do

import site
site.getsitepackages() # List of global package locations

and

site.getusersitepackages() # String for user-specific package location

For locations third-party packages (those not in the core Python distribution) are installed to.

On my Homebrew-installed Python on macOS, the former outputs

['/usr/local/Cellar/python/3.7.4/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages'],

which canonicalizes to the same path output by pip show, as mentioned in a previous answer:

$ readlink -f /usr/local/Cellar/python/3.7.4/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages
/usr/local/lib/python3.7/site-packages

Here is working code that defines a subroutine make_3d_array to allocate a multidimensional 3D array with N1, N2 and N3 elements in each dimension, and then populates it with random numbers. You can use the notation A[i][j][k] to access its elements.

#include <stdio.h>
#include <stdlib.h>
#include <time.h>


// Method to allocate a 2D array of floats
float*** make_3d_array(int nx, int ny, int nz) {
    float*** arr;
    int i,j;

    arr = (float ***) malloc(nx*sizeof(float**));

    for (i = 0; i < nx; i++) {
        arr[i] = (float **) malloc(ny*sizeof(float*));

        for(j = 0; j < ny; j++) {
            arr[i][j] = (float *) malloc(nz * sizeof(float));
        }
    }

    return arr;
} 



int main(int argc, char *argv[])
{
    int i, j, k;
    size_t N1=10,N2=20,N3=5;

    // allocates 3D array
    float ***ran = make_3d_array(N1, N2, N3);

    // initialize pseudo-random number generator
    srand(time(NULL)); 

    // populates the array with random numbers
    for (i = 0; i < N1; i++){
        for (j=0; j<N2; j++) {
            for (k=0; k<N3; k++) {
                ran[i][j][k] = ((float)rand()/(float)(RAND_MAX));
            }
        }
   }

    // prints values
    for (i=0; i<N1; i++) {
        for (j=0; j<N2; j++) {
            for (k=0; k<N3; k++) {
                printf("A[%d][%d][%d] = %f \n", i,j,k,ran[i][j][k]);
            }
        }
    }

    free(ran);
}

>>> from bson import Binary, Code
>>> from bson.json_util import dumps
>>> dumps([{'foo': [1, 2]},
...        {'bar': {'hello': 'world'}},
...        {'code': Code("function x() { return 1; }")},
...        {'bin': Binary("")}])
'[{"foo": [1, 2]}, {"bar": {"hello": "world"}}, {"code": {"$code": "function x() { return 1; }", "$scope": {}}}, {"bin": {"$binary": "AQIDBA==", "$type": "00"}}]'

Actual example from json_util.

Unlike Flask's jsonify, "dumps" will return a string, so it cannot be used as a 1:1 replacement of Flask's jsonify.

But this question shows that we can serialize using json_util.dumps(), convert back to dict using json.loads() and finally call Flask's jsonify on it.

Example (derived from previous question's answer):

from bson import json_util, ObjectId
import json

#Lets create some dummy document to prove it will work
page = {'foo': ObjectId(), 'bar': [ObjectId(), ObjectId()]}

#Dump loaded BSON to valid JSON string and reload it as dict
page_sanitized = json.loads(json_util.dumps(page))
return page_sanitized

This solution will convert ObjectId and others (ie Binary, Code, etc) to a string equivalent such as "$oid."

JSON output would look like this:

{
  "_id": {
    "$oid": "abc123"
  }
}

This is how I was able to trigger a button click when the page loads.

<li ng-repeat="a in array">
  <a class="button" id="btn" ng-click="function(a)" index="$index" on-load-clicker>
    {{a.name}}
  </a>
</li>

A simple directive that takes the index from the ng-repeat and uses a condition to call the first button in the index and click it when the page loads.

angular
    .module("myApp")
        .directive('onLoadClicker', function ($timeout) {
            return {
                restrict: 'A',
                scope: {
                    index: '=index'
                },
                link: function($scope, iElm) {
                    if ($scope.index == 0) {
                        $timeout(function() {

                            iElm.triggerHandler('click');

                        }, 0);
                    }
                }
            };
        });

This was the only way I was able to even trigger an auto click programmatically in the first place. angular.element(document.querySelector('#btn')).click(); Did not work from the controller so making this simple directive seems most effective if you are trying to run a click on page load and you can specify which button to click by passing in the index. I got help through this stack-overflow answer from another post reference: https://stackoverflow.com/a/26495541/4684183 onLoadClicker Directive.

The general idea is to sweep the function across. You have many options, one is apply():

R> set.seed(42)
R> M <- matrix(rnorm(40),ncol=4)
R> apply(M, 2, sd)
[1] 0.835449 1.630584 1.156058 1.115269
R> 

Python 3 has this:

from typing import List

def isit(value):
    return isinstance(value, List)

isit([1, 2, 3])  # True
isit("test")  # False
isit({"Hello": "Mars"})  # False
isit((1, 2))  # False

So to check for both Lists and Tuples, it would be:

from typing import List, Tuple

def isit(value):
    return isinstance(value, List) or isinstance(value, Tuple)

aptitude show postgresql | grep Version worked for me

You can use the minDate property, like this:

$("input.DateFrom").datepicker({
    changeMonth: true, 
    changeYear: true, 
    dateFormat: 'yy-mm-dd',
    minDate: 0, // 0 days offset = today
    maxDate: 'today',
    onSelect: function(dateText) {
        $sD = new Date(dateText);
        $("input#DateTo").datepicker('option', 'minDate', min);
    }
});

You can also specify a date, like this:

minDate: new Date(), // = today

Try git checkout -f master.

-f or --force

When switching branches, proceed even if the index or the working tree differs from HEAD. This is used to throw away local changes.

When checking out paths from the index, do not fail upon unmerged entries; instead, unmerged entries are ignored.

Use nested dictionaries. Take a look:

INI File: example.ini

[Section]
Key = Value

Code:

class IniOpen:
    def __init__(self, file):
        self.parse = {}
        self.file = file
        self.open = open(file, "r")
        self.f_read = self.open.read()
        split_content = self.f_read.split("\n")

        section = ""
        pairs = ""

        for i in range(len(split_content)):
            if split_content[i].find("[") != -1:
                section = split_content[i]
                section = string_between(section, "[", "]")  # define your own function
                self.parse.update({section: {}})
            elif split_content[i].find("[") == -1 and split_content[i].find("="):
                pairs = split_content[i]
                split_pairs = pairs.split("=")
                key = split_pairs[0].trim()
                value = split_pairs[1].trim()
                self.parse[section].update({key: value})

    def read(self, section, key):
        try:
            return self.parse[section][key]
        except KeyError:
            return "Sepcified Key Not Found!"

    def write(self, section, key, value):
        if self.parse.get(section) is  None:
            self.parse.update({section: {}})
        elif self.parse.get(section) is not None:
            if self.parse[section].get(key) is None:
                self.parse[section].update({key: value})
            elif self.parse[section].get(key) is not None:
                return "Content Already Exists"

Apply code like so:

ini_file = IniOpen("example.ini")
print(ini_file.parse) # prints the entire nested dictionary
print(ini_file.read("Section", "Key") # >> Returns Value
ini_file.write("NewSection", "NewKey", "New Value"

Although I do like and appreciate Suragch's answer, I would like to leave a note because I found that coding the Adapter (MyRecyclerViewAdapter) to define and expose the Listener method onItemClick isn't the best way to do it, due to not using class encapsulation correctly. So my suggestion is to let the Adapter handle the Listening operations solely (that's his purpose!) and separate those from the Activity that uses the Adapter (MainActivity). So this is how I would set the Adapter class:

MyRecyclerViewAdapter.java

public class MyRecyclerViewAdapter extends RecyclerView.Adapter<MyRecyclerViewAdapter.ViewHolder> {

    private String[] mData = new String[0];
    private LayoutInflater mInflater;

    // Data is passed into the constructor
    public MyRecyclerViewAdapter(Context context, String[] data) {
        this.mInflater = LayoutInflater.from(context);
        this.mData = data;
    }

    // Inflates the cell layout from xml when needed
    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = mInflater.inflate(R.layout.recyclerview_item, parent, false);
        ViewHolder viewHolder = new ViewHolder(view);
        return viewHolder;
    }

    // Binds the data to the textview in each cell
    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        String animal = mData[position];
        holder.myTextView.setText(animal);
    }

    // Total number of cells
    @Override
    public int getItemCount() {
        return mData.length;
    }

    // Stores and recycles views as they are scrolled off screen
    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        public TextView myTextView;

        public ViewHolder(View itemView) {
            super(itemView);
            myTextView = (TextView) itemView.findViewById(R.id.info_text);
            itemView.setOnClickListener(this);
        }

        @Override
        public void onClick(View view) {
            onItemClick(view, getAdapterPosition());
        }
    }

    // Convenience method for getting data at click position
    public String getItem(int id) {
        return mData[id];
    }

    // Method that executes your code for the action received
    public void onItemClick(View view, int position) {
        Log.i("TAG", "You clicked number " + getItem(position).toString() + ", which is at cell position " + position);
    }
}

Please note the onItemClick method now defined in MyRecyclerViewAdapter that is the place where you would want to code your tasks for the event/action received.

There is only a small change to be done in order to complete this transformation: the Activity doesn't need to implement MyRecyclerViewAdapter.ItemClickListener anymore, because now that is done completely by the Adapter. This would then be the final modification:

MainActivity.java

public class MainActivity extends AppCompatActivity {

    MyRecyclerViewAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

It is “old-fashioned” way to specify ranges of revisions you wish to merge. With 1.5+ you can use:

svn merge HEAD url/of/trunk path/to/branch/wc

The answers provided did not work for me (Chrome or Firefox) while creating PWA for local development and testing. DO NOT USE FOR PRODUCTION! I was able to use the following:

1. Online certificate tools site with the following options:
   • Common Names: Add both the "localhost" and IP of your system e.g. 192.168.1.12
   • Subject Alternative Names: Add "DNS" = "localhost" and "IP" = <your ip here, e.g. 192.168.1.12>
   • "CRS" drop down options set to "Self Sign"
   • all other options were defaults
2. Download all links
3. Import .p7b cert into Windows by double clicking and select "install"/ OSX?/Linux?
4. Added certs to node app... using Google's PWA example
   • add const https = require('https'); const fs = require('fs'); to the top of the server.js file
   • comment out return app.listen(PORT, () => { ... }); at the bottom of server.js file
   • add below https.createServer({ key: fs.readFileSync('./cert.key','utf8'), cert: fs.readFileSync('./cert.crt','utf8'), requestCert: false, rejectUnauthorized: false }, app).listen(PORT)

I have no more errors in Chrome or Firefox

Here is a literal pure Python translation of the Welford's algorithm implementation from http://www.johndcook.com/standard_deviation.html:

https://github.com/liyanage/python-modules/blob/master/running_stats.py

import math

class RunningStats:

    def __init__(self):
        self.n = 0
        self.old_m = 0
        self.new_m = 0
        self.old_s = 0
        self.new_s = 0

    def clear(self):
        self.n = 0

    def push(self, x):
        self.n += 1

        if self.n == 1:
            self.old_m = self.new_m = x
            self.old_s = 0
        else:
            self.new_m = self.old_m + (x - self.old_m) / self.n
            self.new_s = self.old_s + (x - self.old_m) * (x - self.new_m)

            self.old_m = self.new_m
            self.old_s = self.new_s

    def mean(self):
        return self.new_m if self.n else 0.0

    def variance(self):
        return self.new_s / (self.n - 1) if self.n > 1 else 0.0

    def standard_deviation(self):
        return math.sqrt(self.variance())

Usage:

rs = RunningStats()
rs.push(17.0)
rs.push(19.0)
rs.push(24.0)

mean = rs.mean()
variance = rs.variance()
stdev = rs.standard_deviation()

print(f'Mean: {mean}, Variance: {variance}, Std. Dev.: {stdev}')

I had forgotten to set headers: {"Content-Type": "application/json"} in the request. Changing it solved the problem.

Overlapping occurences:

    l = len(pattern)
    ct = 0
    for c in range(0,len(string)):
        if string[c:c+l] == pattern:
            ct += 1
    return ct

test = 'my maaather lies over the oceaaan'

It also disturb me a lot but now it is fine The solution is very simple (written blow) [window (android studio)]

1. go to C:\Users\your user name.gradle
2. open wrapper/dists and delete the folder that is distrubing you in my case --gradle-6.5--
3. then go back to .gradle folder and this time open daemon folder and delete the folder with same number that is disturbing you in my case --6.5--
4. Then again go back to .gradle folder and this time open caches folder and delete the folder with same number that is disturbing you in my case --6.5--
5. now if your android studio is open then close it and again start it but this time with administrator mode by right clicking on the icon of android studio icon it is important
6. you should have internet connection and now your android studio will setup every thing by its own (please don't distrub it while it is doing its operation)

For your actual form, if you were to just post the results to your same page, it should probably work out all right. Try something like:

<form action=<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?> method="POST>

Just add:

left: calc(-50vw + 50%);
right: calc(-50vw + 50%);
margin-left: auto;
margin-right: auto;

You could use IIF statement like in the next example:

SELECT
   IIF(test_expression, value_if_true, value_if_false) AS FIELD_NAME
FROM
   TABLE_NAME

You could also use

print(tbl_df(df), n=40)

or with the help of the pipe operator

df %>% tbl_df %>% print(n=40)

To print all rows specify tbl_df %>% print(n = Inf)

Sometimes, you have to send message from another Thread to UI thread. This type of scenario occurs when you can't execute Network/IO operations on UI thread.

Below example handles that scenario.

1. You have UI Thread
2. You have to start IO operation and hence you can't run Runnable on UI thread. So post your Runnable to handler on HandlerThread
3. Get the result from Runnable and send it back to UI thread and show a Toast message.

Solution:

1. Create a HandlerThread and start it
2. Create a Handler with Looper from HandlerThread:requestHandler
3. Create a Handler with Looper from Main Thread: responseHandler and override handleMessage method
4. post a Runnable task on requestHandler
5. Inside Runnable task, call sendMessage on responseHandler
6. This sendMessage result invocation of handleMessage in responseHandler.
7. Get attributes from the Message and process it, update UI

Sample code:

    /* Handler thread */

    HandlerThread handlerThread = new HandlerThread("HandlerThread");
    handlerThread.start();
    Handler requestHandler = new Handler(handlerThread.getLooper());

    final Handler responseHandler = new Handler(Looper.getMainLooper()) {
        @Override
        public void handleMessage(Message msg) {
            //txtView.setText((String) msg.obj);
            Toast.makeText(MainActivity.this,
                    "Runnable on HandlerThread is completed and got result:"+(String)msg.obj,
                    Toast.LENGTH_LONG)
                    .show();
        }
    };

    for ( int i=0; i<5; i++) {
        Runnable myRunnable = new Runnable() {
            @Override
            public void run() {
                try {

                    /* Add your business logic here and construct the 
                       Messgae which should be handled in UI thread. For 
                       example sake, just sending a simple Text here*/

                    String text = "" + (++rId);
                    Message msg = new Message();

                    msg.obj = text.toString();
                    responseHandler.sendMessage(msg);
                    System.out.println(text.toString());

                } catch (Exception err) {
                    err.printStackTrace();
                }
            }
        };
        requestHandler.post(myRunnable);
    }

Try doing something like the following in main:

public static void main(String[] args) {
     PropertyConfigurator.configure(args[0]);
    //... your code

you need to tell log4j what its configuration should be.

It would be beneficial to verify the form's data before sending it via POST. You should create a JavaScript function to check the form for errors and then send the form. This would prevent the data from being sent over and over again, possibly slowing the browser and using transfer volume on the server.

Edit:

If security is a concern, performing an AJAX request to verify the data would be the best way. The response from the AJAX request would determine whether the form should be submitted.

You can try to use that class. The limitation is that it can't be used outside of one process.

Inside the workbench right click the table in question and click "Select Rows - Limit 1000." It's the first option in the pop-up menu.

Avoid direct references to '@@ERROR'. It's a flighty little thing that can be lost.

Declare @ErrorCode int;
... perform stuff ...
Set @ErrorCode = @@ERROR;
... other stuff ...
if @ErrorCode ...... 

You would find the array keys with "${!foo[@]}" (reference), so:

for i in "${!foo[@]}"; do 
  printf "%s\t%s\n" "$i" "${foo[$i]}"
done

Which means that indices will be in $i while the elements themselves have to be accessed via ${foo[$i]}

Be aware, that your code is quite noisy. I know the thread is old, but a lot of people will read it anyway. You could do the same thing using the guava library with:

    }

Update your working copy to the selected revision. Useful if you want to have your working copy reflect a time in the past, or if there have been further commits to the repository and you want to update your working copy one step at a time. It is best to update a whole directory in your working copy, not just one file, otherwise your working copy could be inconsistent. This is used to test a specific rev purpose, if your test has done, you can use this command to test another rev or use SVN Update to get HEAD

If you want to undo an earlier change permanently, use Revert to this revision instead.

-- from TSVN help doc

If you Update your working copy to an earlier rev, this is only affect your own working copy, after you do some change, and want to commit, you will fail,TSVN will alert you to update your WC to latest revision first If you Revert to a rev, you can commit to repository.everyone will back to the rev after they do an update.

You should use getActivity() method in order to finish the activity from the fragment.

In here you can save the phone number as international formatted phone number

internationalFormatPhoneNumber = phoneUtil.format(givenPhoneNumber, PhoneNumberFormat.INTERNATIONAL);

it return the phone number as International format +94 71 560 4888

so now I have get country code as this

String countryCode = internationalFormatPhoneNumber.substring(0,internationalFormatPhoneNumber.indexOf('')).replace('+', ' ').trim();

Hope this will help you

You did not install the correct Eclipse distribution. Try install the one labeled "Eclipse IDE for Java EE Developers".

I wound up writing my own command-line tool to take care of this. It's similar to cut, except it knows what to do with quoted fields, etc. This tool, paired with @Jimothy's answer, allows me to get a headerless CSV from a remote MySQL server I have no filesystem access to onto my local machine with this command:

$ mysql -N -e "select people, places from things" | csvm -i '\t' -o ','

To answer the question. stringstream basically allows you to treat a string object like a stream, and use all stream functions and operators on it.

I saw it used mainly for the formatted output/input goodness.

One good example would be c++ implementation of converting number to stream object.

Possible example:

template <class T>
string num2str(const T& num, unsigned int prec = 12) {
    string ret;
    stringstream ss;
    ios_base::fmtflags ff = ss.flags();
    ff |= ios_base::floatfield;
    ff |= ios_base::fixed;
    ss.flags(ff);
    ss.precision(prec);
    ss << num;
    ret = ss.str();
    return ret;
};

Maybe it's a bit complicated but it is quite complex. You create stringstream object ss, modify its flags, put a number into it with operator<<, and extract it via str(). I guess that operator>> could be used.

Also in this example the string buffer is hidden and not used explicitly. But it would be too long of a post to write about every possible aspect and use-case.

Note: I probably stole it from someone on SO and refined, but I don't have original author noted.

If anyone like me is searching to read only a specific line, example only line 18 here is the code:

filename = "C:\log.log"

Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)

For i = 1 to 17
    f.ReadLine
Next

strLine = f.ReadLine
Wscript.Echo strLine

f.Close

An entity manager can only be injected in classes running inside a transaction. In other words, it can only be injected in a EJB. Other classe must use an EntityManagerFactory to create and destroy an EntityManager.

Since your TestService is not an EJB, the annotation @PersistenceContext is simply ignored. Not only that, in JavaEE 5, it's not possible to inject an EntityManager nor an EntityManagerFactory in a JAX-RS Service. You have to go with a JavaEE 6 server (JBoss 6, Glassfish 3, etc).

Here's an example of injecting an EntityManagerFactory:

package com.test.service;

import java.util.*;
import javax.persistence.*;
import javax.ws.rs.*;

@Path("/service")
public class TestService {

    @PersistenceUnit(unitName = "test")
    private EntityManagerFactory entityManagerFactory;

    @GET
    @Path("/get")
    @Produces("application/json")
    public List get() {
        EntityManager entityManager = entityManagerFactory.createEntityManager();
        try {
            return entityManager.createQuery("from TestEntity").getResultList();
        } finally {
            entityManager.close();
        }
    }
}

The easiest way to go here is to declare your service as a EJB 3.1, assuming you're using a JavaEE 6 server.

Related question: Inject an EJB into JAX-RS (RESTful service)

def transpose(matrix):
    listOfLists = []
    for row in range(len(matrix[0])):
        colList = []

Using HTTP status codes would be a RESTful way to do it, but that would suggest you make the rest of the interface RESTful using resource URIs and so on.

In truth, define the interface as you like (return an error object, for example, detailing the property with the error, and a chunk of HTML that explains it, etc), but once you've decided on something that works in a prototype, be ruthlessly consistent.

"[1-9][0-9]*|0"

I'd just use "[0-9]+" to represent positive whole numbers.

A simple for loop?

for i in range(3):

Or, if you're interested in the results and want to collect them, with the bonus of being a 1 liner:

vals = [do() for _ in range(3)]

the colums "avm" and "fre" tell you the total memory and free memery.

a "man vmstat" should get you the gory details.

} 

There are JDK versions available from the base CentOS repositories. Depending on your version of CentOS, and the JDK you want to install, the following as root should give you what you want:

OpenJDK Runtime Environment (Java SE 6)

yum install java-1.6.0-openjdk

OpenJDK Runtime Environment (Java SE 7)

yum install java-1.7.0-openjdk

OpenJDK Development Environment (Java SE 7)

yum install java-1.7.0-openjdk-devel

OpenJDK Development Environment (Java SE 6)

yum install java-1.6.0-openjdk-devel

Update for Java 8

In CentOS 6.6 or later, Java 8 is available. Similar to 6 and 7 above, the packages are as follows:

OpenJDK Runtime Environment (Java SE 8)

yum install java-1.8.0-openjdk

OpenJDK Development Environment (Java SE 8)

yum install java-1.8.0-openjdk-devel

There's also a 'headless' JRE package that is the same as the above JRE, except it doesn't contain audio/video support. This can be used for a slightly more minimal installation:

OpenJDK Runtime Environment - Headless (Java SE 8)

yum install java-1.8.0-openjdk-headless

It's as simple as it name.

• Make your first pivot table.

• Select the first top left cell.

• Create a range name using offset:

  OFFSET(Sheet1!$A$3,0,0,COUNTA(Sheet1!$A:$A)-1,COUNTA(Sheet1!$3:$3))

• Make your second pivot with your range name as source of data using F3.

If you change number of rows or columns from your first pivot, your second pivot will be update after refreshing pivot

I just want to add, if you get this error because you are using Cygwin make and auto-generated files, you can fix it with the following sed,

sed -e 's@\\\([^ ]\)@/\1@g' -e 's@[cC]:@/cygdrive/c@' -i filename.d

You may need to add more characters than just space to the escape list in the first substitution but you get the idea. The concept here is that /cygdrive/c is an alias for c: that cygwin's make will recognize.

And may as well throw in

-e 's@^ \+@\t@'

just in case you did start with spaces on accident (although I /think/ this will usually be a "missing separator" error).

If you want your UIView shift properly and your active textfield should accurately position to user need so that he/she can see whatever they are input .

For that you must use Scrollview . This suppose to be your UIView hierarchy . ContainerView -> ScrollView -> ContentView -> Your View .

If you have made UIView design as per above discuss hierarchy, now in your controller class you need add notifications observer in viewwillappear and remove observer in viewwilldissappear .

But this approach needs to add on every controller where ever UIView need to shifts . I have been using 'TPKeyboardAvoiding' pod . It is reliable and easily handle shift of UIView for every possible case wether if you are Scrollview , TableView or CollectionView . You just need to pass class to your 'scrolling view' .

You can change this class if you are tableview to 'TPKeyboardAvoidingTableView'. You can find complete running project Project Link

This robust approach I've been followed for development . Hope this helps!

It's Quite easy using Google Distance Matrix service

First step is to activate Distance Matrix service from google API console. it returns distances between a set of locations. And apply this simple function

function initMap() {
        var bounds = new google.maps.LatLngBounds;
        var markersArray = [];

        var origin1 = {lat:23.0203, lng: 72.5562};
        //var origin2 = 'Ahmedabad, India';
        var destinationA = {lat:23.0436503, lng: 72.55008939999993};
        //var destinationB = {lat: 23.2156, lng: 72.6369};

        var destinationIcon = 'https://chart.googleapis.com/chart?' +
            'chst=d_map_pin_letter&chld=D|FF0000|000000';
        var originIcon = 'https://chart.googleapis.com/chart?' +
            'chst=d_map_pin_letter&chld=O|FFFF00|000000';
        var map = new google.maps.Map(document.getElementById('map'), {
          center: {lat: 55.53, lng: 9.4},
          zoom: 10
        });
        var geocoder = new google.maps.Geocoder;

        var service = new google.maps.DistanceMatrixService;
        service.getDistanceMatrix({
          origins: [origin1],
          destinations: [destinationA],
          travelMode: 'DRIVING',
          unitSystem: google.maps.UnitSystem.METRIC,
          avoidHighways: false,
          avoidTolls: false
        }, function(response, status) {
          if (status !== 'OK') {
            alert('Error was: ' + status);
          } else {
            var originList = response.originAddresses;
            var destinationList = response.destinationAddresses;
            var outputDiv = document.getElementById('output');
            outputDiv.innerHTML = '';
            deleteMarkers(markersArray);

            var showGeocodedAddressOnMap = function(asDestination) {
              var icon = asDestination ? destinationIcon : originIcon;
              return function(results, status) {
                if (status === 'OK') {
                  map.fitBounds(bounds.extend(results[0].geometry.location));
                  markersArray.push(new google.maps.Marker({
                    map: map,
                    position: results[0].geometry.location,
                    icon: icon
                  }));
                } else {
                  alert('Geocode was not successful due to: ' + status);
                }
              };
            };

            for (var i = 0; i < originList.length; i++) {
              var results = response.rows[i].elements;
              geocoder.geocode({'address': originList[i]},
                  showGeocodedAddressOnMap(false));
              for (var j = 0; j < results.length; j++) {
                geocoder.geocode({'address': destinationList[j]},
                    showGeocodedAddressOnMap(true));
                //outputDiv.innerHTML += originList[i] + ' to ' + destinationList[j] + ': ' + results[j].distance.text + ' in ' +                    results[j].duration.text + '<br>';
                outputDiv.innerHTML += results[j].distance.text + '<br>';
              }
            }

          }
        });
      }

Where origin1 is your location and destinationA is destindation location.you can add above two or more data.

Simply add class="img-responsive" to the video tag. I'm doing this on a current project, and it works. It doesn't need to be wrapped in anything.

<video class="img-responsive" src="file.mp4" autoplay loop/>

By simply adding fiddler to the url

http://localhost.fiddler:8081/

Traffic is routed through fiddler and therefore being displayed on fiddler.

Use this example

System.Globalization.CultureInfo culInfo = new System.Globalization.CultureInfo("en-GB",true);

decimal currency_usd = decimal.Parse(GetRateFromCbrf("usd"),culInfo);
decimal currency_eur = decimal.Parse(GetRateFromCbrf("eur"), culInfo);

you can use

Array.forEach

example:

function logArrayElements(element, index, array) {  
    console.log("a[" + index + "] = " + element);  
}  
[2, 5, 9].forEach(logArrayElements)

or with jQuery

$.each([52, 97], function(index, value) { 
  alert(index + ': ' + value); 
});

http://api.jquery.com/jQuery.each/

Try this one. Hope this is working fine.. :)

You didn't bind all your bindings here

$sql = "SELECT SQL_CALC_FOUND_ROWS *, UNIX_TIMESTAMP(publicationDate) AS publicationDate     FROM comments WHERE articleid = :art 
ORDER BY " . mysqli_escape_string($order) . " LIMIT :numRows";

$st = $conn->prepare( $sql );
$st->bindValue( ":art", $art, PDO::PARAM_INT );

You've declared a binding called :numRows but you never actually bind anything to it.

UPDATE 2019: I keep getting upvotes on this and that reminded me of another suggestion

Double quotes are string interpolation in PHP, so if you're going to use variables in a double quotes string, it's pointless to use the concat operator. On the flip side, single quotes are not string interpolation, so if you've only got like one variable at the end of a string it can make sense, or just use it for the whole string.

In fact, there's a micro op available here since the interpreter doesn't care about parsing the string for variables. The boost is nearly unnoticable and totally ignorable on a small scale. However, in a very large application, especially good old legacy monoliths, there can be a noticeable performance increase if strings are used like this. (and IMO, it's easier to read anyway)

I used LinearLayout instead of Button. The OnClickListener, which I need to use works fine also for LinearLayout.

<LinearLayout
    android:id="@+id/my_button"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/selector"
    android:gravity="center"
    android:orientation="horizontal"
    android:clickable="true">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="15dp"
        android:adjustViewBounds="true"
        android:scaleType="fitCenter"
        android:src="@drawable/icon" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="Text" />

</LinearLayout>

While most people blindly follow the advice of the javadoc, there are very specific situations where you want to actually avoid toString(). For example, I'm using enums in my Java code, but they need to be serialized to a database, and back again. If I used toString() then I would technically be subject to getting the overridden behavior as others have pointed out.

Additionally one can also de-serialize from the database, for example, this should always work in Java:

MyEnum taco = MyEnum.valueOf(MyEnum.TACO.name());

Whereas this is not guaranteed:

MyEnum taco = MyEnum.valueOf(MyEnum.TACO.toString());

By the way, I find it very odd for the Javadoc to explicitly say "most programmers should". I find very little use-case in the toString of an enum, if people are using that for a "friendly name" that's clearly a poor use-case as they should be using something more compatible with i18n, which would, in most cases, use the name() method.

There are two possible ways to implement it. The easiest way is direct result to dev/null

exec("run_baby_run > /dev/null 2>&1 &");

But in case you have any other operations to be performed you may consider ignore_user_abort In this case the script will be running even after you close connection.

For those receiving this warning for the first time, it is due to a bleeding edge feature called Passive Event Listeners that has been implemented in browsers fairly recently (summer 2016). From https://github.com/WICG/EventListenerOptions/blob/gh-pages/explainer.md:

Passive event listeners are a new feature in the DOM spec that enable developers to opt-in to better scroll performance by eliminating the need for scrolling to block on touch and wheel event listeners. Developers can annotate touch and wheel listeners with {passive: true} to indicate that they will never invoke preventDefault. This feature shipped in Chrome 51, Firefox 49 and landed in WebKit. For full official explanation read more here.

See also: What are passive event listeners?

You may have to wait for your .js library to implement support.

If you are handling events indirectly via a JavaScript library, you may be at the mercy of that particular library's support for the feature. As of December 2019, it does not look like any of the major libraries have implemented support. Some examples:

• jQuery.js - ongoing issue: https://github.com/jquery/jquery/issues/2871
• React.js - ongoing issue: https://github.com/facebook/react/issues/6436
• Hammer.js - closed due to no follow up: https://github.com/hammerjs/hammer.js/pull/987
• perfect-scrollbar - closed: https://github.com/noraesae/perfect-scrollbar/issues/560
• AngularJS - closed due to won't fix: https://github.com/angular/angular.js/issues/15901

I had done something that relates to this... Below is a sample javascript with what you need. There is a demo on this here: http://codersfolder.com/2016/07/crud-with-php-mysqli-bootstrap-datatables-jquery-plugin/

//global the manage member table 
var manageMemberTable;

function updateMember(id = null) {
    if(id) {
        // click on update button
        $("#updatebutton").unbind('click').bind('click', function() {
            $.ajax({
                url: 'webdesign_action/update.php',
                type: 'post',
                data: {member_id : id},
                dataType: 'json',
                success:function(response) {
                    if(response.success == true) {                      
                        $(".removeMessages").html('<div class="alert alert-success alert-dismissible" role="alert">'+
                              '<button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>'+
                              '<strong> <span class="glyphicon glyphicon-ok-sign"></span> </strong>'+response.messages+
                            '</div>');

                        // refresh the table

                        manageMemberTable.ajax.reload();

                        // close the modal
                        $("#updateModal").modal('hide');

                    } else {
                        $(".removeMessages").html('<div class="alert alert-warning alert-dismissible" role="alert">'+
                              '<button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">&times;</span></button>'+
                              '<strong> <span class="glyphicon glyphicon-exclamation-sign"></span> </strong>'+response.messages+
                            '</div>');

                        // refresh the table                        
                        manageMemberTable.ajax.reload();

                        // close the modal
                        $("#updateModal").modal('hide');
                    }
                }
            });
        }); // click remove btn
    } else {
        alert('Error: Refresh the page again');
    }
}

yes, supposing your variable is in the global namespace:

<button onclick="myVar += 1;alert('myVar now equals ' + myVar)">Increment!!</button>

The replace method in Javascript returns a value, and does not act upon the existing string object. See: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/replace

In your example, you will have to do

$(this).attr("src", $(this).attr("src").replace(...))

Git version 2.9.2

If you want to change the name of the local branch you are on:

git branch -m new_name

If you want to change the name of a different branch:

git branch -m old_name new_name

If you want to change the name of a different branch to a name that already exists:

git branch -M old_name new_name_that_already_exists

Note: The last command is destructive and will rename your branch, but you will lose the old branch with that name and those commits because branch names must be unique.

Another potential cause for this error: Attempting to get permission for a Facebook app in sandbox mode when the Facebook user is not listed in the app's admins, developers or testers.

A convinient way is using the package python-dotenv: It reads out a .flaskenv file where you can store environment variables for flask.

• pip install python-dotenv
• create a file .flaskenv in the root directory of your app

Inside the file you specify:

FLASK_APP=application.py
FLASK_RUN_HOST=localhost
FLASK_RUN_PORT=80

After that you just have to run your app with flask run and can access your app at that port.

Please note that FLASK_RUN_HOST defaults to 127.0.0.1 and FLASK_RUN_PORT defaults to 5000.

There's no need to use a lambda, when you can remove all the null ones, and put one back if the input size changes:

input = [Object(name=""), Object(name="fake_name"), Object(name="")] 
output = [x for x in input if x.name]
if(len(input) != len(output)):
    output.append(Object(name=""))

You can actually provide implementations of pure virtual functions in C++. The only difference is all pure virtual functions must be implemented by derived classes before the class can be instantiated.

You can use the below Code

public static class ExtensionMethods
{
    public static IEnumerable<T> GetAll<T>(this Control control)
    {
        var controls = control.Controls.Cast<Control>();

        return controls.SelectMany(ctrl => ctrl.GetAll<T>())
                                  .Concat(controls.OfType<T>());
    }
}

The Global.asax can be used to handle events arising from the application. This link provides a good explanation: http://aspalliance.com/1114

If you don't have a 3.7 for @dataclass and need mutability, the following code might work for you. It's quite self-documenting and IDE-friendly (auto-complete), prevents writing things twice, is easily extendable and it is very simple to test that all instance variables are completely initialized:

class Params():
    def __init__(self):
        self.var1 : int = None
        self.var2 : str = None

    def are_all_defined(self):
        for key, value in self.__dict__.items():
            assert (value is not None), "instance variable {} is still None".format(key)
        return True


params = Params()
params.var1 = 2
params.var2 = 'hello'
assert(params.are_all_defined)

You could add \singlespacing near the beginning of your table. See the setspace instructions for more options.

CORRECTION: I found out that the above solution is terrible. Especially when your phone is slow. And here, I found another solution: calculate out the px value of the element, including the margins and paddings: dp to px: https://stackoverflow.com/a/6327095/1982712

or dimens.xml to px: https://stackoverflow.com/a/16276351/1982712

sp to px: https://stackoverflow.com/a/9219417/1982712 (reverse the solution)

or dimens to px: https://stackoverflow.com/a/16276351/1982712

and that's it.

The only thing about using telnet to test postfix, or other SMTP, is that you have to know the commands and syntax. Instead, just use swaks :)

It's just one easy command.

You can define a Headers object with a dictionary of HTTP key/value pairs, and then pass it in as an argument to http.get() and http.post() like this:

const headerDict = {
  'Content-Type': 'application/json',
  'Accept': 'application/json',
  'Access-Control-Allow-Headers': 'Content-Type',
}

const requestOptions = {                                                                                                                                                                                 
  headers: new Headers(headerDict), 
};

return this.http.get(this.heroesUrl, requestOptions)

Or, if it's a POST request:

const data = JSON.stringify(heroData);
return this.http.post(this.heroesUrl, data, requestOptions);

Since Angular 7 and up you have to use HttpHeaders class instead of Headers:

const requestOptions = {                                                                                                                                                                                 
  headers: new HttpHeaders(headerDict), 
};

Assuming the changes you want are at the head of the branch you want the changes from, use git checkout

for a single file :

git checkout branch_that_has_the_changes_you_want path/to/file.rb

for multiple files just daisy chain :

git checkout branch_that_has_the_changes_you_want path/to/file.rb path/to/other_file.rb

Another way is to pass the file into mongo in your terminal prompt.

$ mongo < myjstest.js

This will start a mongo session, run the file, then exit. Not sure about calling a 2nd file from the 1st however. I haven't tried it.

The default keyword parameter should be given to the Column object.

Example:

Column(u'timestamp', TIMESTAMP(timezone=True), primary_key=False, nullable=False, default=time_now),

The default value can be a callable, which here I defined like the following.

from pytz import timezone
from datetime import datetime

UTC = timezone('UTC')

def time_now():
    return datetime.now(UTC)

ObjectReader reader = new ObjectMapper().readerFor(Map.class);

Map<String, String> map = reader.readValue("{\"foo\":\"val\"}");

Note that reader instance is Thread Safe.

no such table exists: error is coming because once you create database with one table after that whenever you create table in same database it gives this error.

To solve this error you must have to create new database and inside the onCreate() method you can create multiple table in same database.
