Another thing on linux is:

send does not allow to operate on non-socket fd. Thus, for example to write on usb port, write is necessary.

Create your own BaseAdapter class and use it as following.

 public class NotificationScreen extends Activity
{

@Override
protected void onCreate_Impl(Bundle savedInstanceState)
{
    setContentView(R.layout.notification_screen);

    ListView notificationList = (ListView) findViewById(R.id.notification_list);
    NotiFicationListAdapter notiFicationListAdapter = new NotiFicationListAdapter();
    notificationList.setAdapter(notiFicationListAdapter);

    homeButton = (Button) findViewById(R.id.home_button);

}

}

Make your own BaseAdapter class and its separate xml file.

public class NotiFicationListAdapter  extends BaseAdapter
{
private ArrayList<HashMap<String, String>> data;
private LayoutInflater inflater=null;


public NotiFicationListAdapter(ArrayList data)
{
this.data=data;        
    inflater =(LayoutInflater)baseActivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}



public int getCount() 
{
 return data.size();
}



public Object getItem(int position) 
{
 return position;
}



public long getItemId(int position) 
{
    return position;
}



public View getView(int position, View convertView, ViewGroup parent) 
{
View vi=convertView;
    if(convertView==null)

    vi = inflater.inflate(R.layout.notification_list_item, null);

    ImageView compleatImageView=(ImageView)vi.findViewById(R.id.complet_image);
    TextView name = (TextView)vi.findViewById(R.id.game_name); // name
    TextView email_id = (TextView)vi.findViewById(R.id.e_mail_id); // email ID
    TextView notification_message = (TextView)vi.findViewById(R.id.notification_message); // notification message



    compleatImageView.setBackgroundResource(R.id.address_book);
    name.setText(data.getIndex(position));
    email_id.setText(data.getIndex(position));
    notification_message.setTextdata.getIndex(position));

    return vi;
}

  }

BaseAdapter xml file.

Change it accordingly and use.

>>> import numpy
>>> x = numpy.zeros((3,4))
>>> x
array([[ 0.,  0.,  0.,  0.],
       [ 0.,  0.,  0.,  0.],
       [ 0.,  0.,  0.,  0.]])
>>> y = numpy.zeros(5)   
>>> y
array([ 0.,  0.,  0.,  0.,  0.])

x is a 2-d array, and y is a 1-d array. They are both initialized with zeros.

If your context is an activity you can call overridePendingTransition:

Call immediately after one of the flavors of startActivity(Intent) or finish to specify an explicit transition animation to perform next.

So, programmatically:

this.startActivity(new Intent(v.getContext(), newactivity.class));
this.overridePendingTransition(0, 0);

The selector would be label[for=email], so in CSS:

label[for=email]
{
    /* ...definitions here... */
}

...or in JavaScript using the DOM:

var element = document.querySelector("label[for=email]");

...or in JavaScript using jQuery:

var element = $("label[for=email]");

It's an attribute selector. Note that some browsers (versions of IE < 8, for instance) may not support attribute selectors, but more recent ones do. To support older browsers like IE6 and IE7, you'd have to use a class (well, or some other structural way), sadly.

(I'm assuming that the template {t _your_email} will fill in a field with id="email". If not, use a class instead.)

Note that if the value of the attribute you're selecting doesn't fit the rules for a CSS identifier (for instance, if it has spaces or brackets in it, or starts with a digit, etc.), you need quotes around the value:

label[for="field[]"]
{
    /* ...definitions here... */
}

They can be single or double quotes.

Lets take fibonacci series as an example

1,1,2,3,5,8,13,21....

first number: 1
Second number: 1
Third Number: 2

Another way to put it,

Bottom(first) number: 1
Top (Eighth) number on the given sequence: 21

In case of first five fibonacci number

Bottom(first) number :1
Top (fifth) number: 5 

Now lets take a look of recursive Fibonacci series algorithm as an example

public int rcursive(int n) {
    if ((n == 1) || (n == 2)) {
        return 1;
    } else {
        return rcursive(n - 1) + rcursive(n - 2);
    }
}

Now if we execute this program with following commands

rcursive(5);

if we closely look into the algorithm, in-order to generate fifth number it requires 3rd and 4th numbers. So my recursion actually start from top(5) and then goes all the way to bottom/lower numbers. This approach is actually top-down approach.

To avoid doing same calculation multiple times we use Dynamic Programming techniques. We store previously computed value and reuse it. This technique is called memoization. There are more to Dynamic programming other then memoization which is not needed to discuss current problem.

Top-Down

Lets rewrite our original algorithm and add memoized techniques.

public int memoized(int n, int[] memo) {
    if (n <= 2) {
        return 1;
    } else if (memo[n] != -1) {
        return memo[n];
    } else {
        memo[n] = memoized(n - 1, memo) + memoized(n - 2, memo);
    }
    return memo[n];
}

And we execute this method like following

   int n = 5;
    int[] memo = new int[n + 1];
    Arrays.fill(memo, -1);
    memoized(n, memo);

This solution is still top-down as algorithm start from top value and go to bottom each step to get our top value.

Bottom-Up

But, question is, can we start from bottom, like from first fibonacci number then walk our way to up. Lets rewrite it using this techniques,

public int dp(int n) {
    int[] output = new int[n + 1];
    output[1] = 1;
    output[2] = 1;
    for (int i = 3; i <= n; i++) {
        output[i] = output[i - 1] + output[i - 2];
    }
    return output[n];
}

Now if we look into this algorithm it actually start from lower values then go to top. If i need 5th fibonacci number i am actually calculating 1st, then second then third all the way to up 5th number. This techniques actually called bottom-up techniques.

Last two, algorithms full-fill dynamic programming requirements. But one is top-down and another one is bottom-up. Both algorithm has similar space and time complexity.

Just edit the Project name by single click on the Top of project navigator window, will work in this case. You need not to try any other thing. :)

Using dplyr:

library(dplyr)

# exclude ID column then get mean
DF %>%
  transmute(ID,
            Mean = rowMeans(select(., -ID)))

Or

# select the columns to include in mean
DF %>%
  transmute(ID,
            Mean = rowMeans(select(., C1:C3)))

#   ID     Mean
# 1  A 3.666667
# 2  B 4.333333
# 3  C 3.333333
# 4  D 4.666667
# 5  E 4.333333

The CURL extension ext/curl is not installed or enabled in your PHP installation. Check the manual for information on how to install or enable CURL on your system.

DateTime.now.new_offset(0)

will work in standard Ruby (i.e. without ActiveSupport).

* Parameter order in the connection string is sometimes important. * The Provider parameter's location can break the recordset cursor after adding a row. We saw this behavior with the SQLOLEDB provider.

After a row is added, the row fields are not available, UNLESS the Provider is specified as the first parameter in the connection string. When the provider is anywhere in the connection string except as the first parameter, the newly inserted row fields are not available. When we moved the the Provider to the first parameter, the row fields magically appeared.

First of all, your variable "isLeapYear" is the same name as the method. That's just bad practice.

Second, you're not declaring "isLeapYear" as a variable. Java is strongly typed so you need a boolean isLeapYear; in the beginning of your method.

This call: System.out.println(boolean isLeapYear); is just wrong. There are no declarations in method calls.

Once you have declared isLeapYear to be a boolean variable, you can call System.out.println(isLeapYear);

UPDATE: I just saw it's declared as a field. So just remove the line System.out.println(boolean isLeapYear); You should understand that you can't call isLeapYear from the main() method. You cannot call a non static method from a static method with an instance. If you want to call it, you need to add

booleanfun myBoolFun = new booleanfun();
System.out.println(myBoolFun.isLeapYear);

I really suggest you use Eclipse, it will let you know of such compilation errors on the fly and its much easier to learn that way.

Your model is @Messages, change it to @message.

To change it like you should use migration:

def change   rename_table :old_table_name, :new_table_name end 

Of course do not create that file by hand but use rails generator:

rails g migration ChangeMessagesToMessage 

That will generate new file with proper timestamp in name in 'db dir. Then run:

rake db:migrate 

And your app should be fine since then.

1.84E-07 is the exact value, represented using scientific notation, also known as exponential notation.

1.845E-07 is the same as 0.0000001845. Excel will display a number very close to 0 as 0, unless you modify the formatting of the cell to display more decimals.

C# however will get the actual value from the cell. The ToString method use the e-notation when converting small numbers to a string.

You can specify a format string if you don't want to use the e-notation.

The code below will produce this plot:

# Split list
n = 6
data = [l[i:i + n] for i in range(0, len(l), n)]

# A dataframe
df = pd.DataFrame(data)

def CorrMtx(df, dropDuplicates = True):

    # Your dataset is already a correlation matrix.
    # If you have a dateset where you need to include the calculation
    # of a correlation matrix, just uncomment the line below:
    # df = df.corr()

    # Exclude duplicate correlations by masking uper right values
    if dropDuplicates:    
        mask = np.zeros_like(df, dtype=np.bool)
        mask[np.triu_indices_from(mask)] = True

    # Set background color / chart style
    sns.set_style(style = 'white')

    # Set up  matplotlib figure
    f, ax = plt.subplots(figsize=(11, 9))

    # Add diverging colormap from red to blue
    cmap = sns.diverging_palette(250, 10, as_cmap=True)

    # Draw correlation plot with or without duplicates
    if dropDuplicates:
        sns.heatmap(df, mask=mask, cmap=cmap, 
                square=True,
                linewidth=.5, cbar_kws={"shrink": .5}, ax=ax)
    else:
        sns.heatmap(df, cmap=cmap, 
                square=True,
                linewidth=.5, cbar_kws={"shrink": .5}, ax=ax)


CorrMtx(df, dropDuplicates = False)

I put this together after it was announced that the outstanding seaborn corrplot was to be deprecated. The snippet above makes a resembling correlation plot based on seaborn heatmap. You can also specify the color range and select whether or not to drop duplicate correlations. Notice that I've used the same numbers as you, but that I've put them in a pandas dataframe. Regarding the choice of colors you can have a look at the documents for sns.diverging_palette. You asked for blue, but that falls out of this particular range of the color scale with your sample data. For both observations of 0.95173379, try changing to -0.95173379 and you'll get this:

Don't worry. But you should still use the second solution (plus an extra check for none of those variables existing), because there are security issues with $_REQUEST (since $_GET and $_POST aren't the only sources for that array).

There was a post about the problems with $_REQUEST yesterday, I believe. Let me go find it.

EDIT: Oh well, not directly a post, but here it is anyway: http://kuza55.blogspot.com/2006/03/request-variable-fixation.html

Possibly, most easy way will be to use:

https://github.com/ukushu/DataExporter

especially in case of your data of datatable containing /r/n characters or separator symbol inside of your dataTable cells. Almost all of other answers will not work with such cells.

only you need is to write the following code:

Csv csv = new Csv("\t");//Needed delimiter 

var columnNames = dt.Columns.Cast<DataColumn>().
    Select(column => column.ColumnName).ToArray();

csv.AddRow(columnNames);

foreach (DataRow row in dt.Rows)
{
    var fields = row.ItemArray.Select(field => field.ToString()).ToArray;
    csv.AddRow(fields);   
}

csv.Save();

One solution to this problem is to use the Handler.postDelayed() method. Some Google training materials suggest the same solution.

@Override
public void onClick(View v) {
    my_button.setBackgroundResource(R.drawable.icon);

    Handler handler = new Handler(); 
    handler.postDelayed(new Runnable() {
         @Override 
         public void run() { 
              my_button.setBackgroundResource(R.drawable.defaultcard); 
         } 
    }, 2000); 
}

However, some have pointed out that the solution above causes a memory leak because it uses a non-static inner and anonymous class which implicitly holds a reference to its outer class, the activity. This is a problem when the activity context is garbage collected.

A more complex solution that avoids the memory leak subclasses the Handler and Runnable with static inner classes inside the activity since static inner classes do not hold an implicit reference to their outer class:

private static class MyHandler extends Handler {}
private final MyHandler mHandler = new MyHandler();

public static class MyRunnable implements Runnable {
    private final WeakReference<Activity> mActivity;

    public MyRunnable(Activity activity) {
        mActivity = new WeakReference<>(activity);
    }

    @Override
    public void run() {
        Activity activity = mActivity.get();
        if (activity != null) {
            Button btn = (Button) activity.findViewById(R.id.button);
            btn.setBackgroundResource(R.drawable.defaultcard);
        }
    }
}

private MyRunnable mRunnable = new MyRunnable(this);

public void onClick(View view) {
    my_button.setBackgroundResource(R.drawable.icon);

    // Execute the Runnable in 2 seconds
    mHandler.postDelayed(mRunnable, 2000);
}

Note that the Runnable uses a WeakReference to the Activity, which is necessary in a static class that needs access to the UI.

I know it's old, but you can:

• Create a service layer
• Move method there
• Call method in both controllers

In my case it was solved just passing proxy to connection. Thanks to @Andreas Panagiotidis.

Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("<YOUR.HOST>", 80)));
HttpsURLConnection con = (HttpsURLConnection) url.openConnection(proxy);

I had some problems with http.get; so I switched to the lib request:

var request = require('request');

var url = 'http://blog.mynotiz.de/';

var options = {
    url: url,
    method: 'HEAD'
};

request(options, function (error, response, body) {
        if (error) {
            return console.error('upload failed:', error);
        }

        if (response.headers['content-length']) {
            var file_size = response.headers['content-length'];
            console.log(file_size);
        }
    }
);

None of the previous answers (to this date) gives the correct difference in days between two dates.

The one that comes closest is by thatdankent. A full answer would convert to_i and then divide:

(Time.now.to_i - 23.hours.ago.to_i) / 86400
>> 0

(Time.now.to_i - 25.hours.ago.to_i) / 86400
>> 1

(Time.now.to_i - 1.day.ago.to_i) / 86400
>> 1

In the question's specific example, one should not parse to Date if the time passed is relevant. Use Time.parse instead.

Update queueAll() method as below:

public Cursor queueAll() {

     String selectQuery = "SELECT * FROM " + MYDATABASE_TABLE;
     Cursor cursor = sqLiteDatabase.rawQuery(selectQuery, null);

     return cursor;
}

Update readFileFromSQLite() method as below:

public ArrayList<String> readFileFromSQLite() {

    fileName = new ArrayList<String>();

    fileSQLiteAdapter = new FileSQLiteAdapter(FileChooser.this);
    fileSQLiteAdapter.openToRead();

    cursor = fileSQLiteAdapter.queueAll();

    if (cursor != null) {
        if (cursor.moveToFirst()) {
            do 
            {
                String name = cursor.getString(cursor.getColumnIndex(FileSQLiteAdapter.KEY_CONTENT1));
                fileName.add(name);
            } while (cursor.moveToNext());
        }
        cursor.close();
    }

    fileSQLiteAdapter.close();

    return fileName;
}

$('elemId').length doesn't work for me.

You need to put # before element id:

$('#elemId').length
---^

With vanilla JavaScript, you don't need the hash (#) e.g. document.getElementById('id_here') , however when using jQuery, you do need to put hash to target elements based on id just like CSS.

For python 3.6

class SomeClass:

    def attr_list(self, should_print=False):

        items = self.__dict__.items()
        if should_print:
            [print(f"attribute: {k}    value: {v}") for k, v in items]

        return items

Try this

{
    "to" : "DEVICE-TOKEN",

    "notification" : {
      "body"  : "NOTIFICATION BODY",
      "title" : "NOTIFICATION TITILE",
      "sound" : "default"
    }
  }

@note for custom notification sound:-> "sound" : "MyCustomeSound.wav"

I used 'extern "C"' before for dll(dynamic link library) files to make etc. main() function "exportable" so it can be used later in another executable from dll. Maybe an example of where I used to use it can be useful.

DLL

#include <string.h>
#include <windows.h>

using namespace std;

#define DLL extern "C" __declspec(dllexport)
//I defined DLL for dllexport function
DLL main ()
{
    MessageBox(NULL,"Hi from DLL","DLL",MB_OK);
}

EXE

#include <string.h>
#include <windows.h>

using namespace std;

typedef LPVOID (WINAPI*Function)();//make a placeholder for function from dll
Function mainDLLFunc;//make a variable for function placeholder

int main()
{
    char winDir[MAX_PATH];//will hold path of above dll
    GetCurrentDirectory(sizeof(winDir),winDir);//dll is in same dir as exe
    strcat(winDir,"\\exmple.dll");//concentrate dll name with path
    HINSTANCE DLL = LoadLibrary(winDir);//load example dll
    if(DLL==NULL)
    {
        FreeLibrary((HMODULE)DLL);//if load fails exit
        return 0;
    }
    mainDLLFunc=(Function)GetProcAddress((HMODULE)DLL, "main");
    //defined variable is used to assign a function from dll
    //GetProcAddress is used to locate function with pre defined extern name "DLL"
    //and matcing function name
    if(mainDLLFunc==NULL)
    {
        FreeLibrary((HMODULE)DLL);//if it fails exit
        return 0;
    }
    mainDLLFunc();//run exported function 
    FreeLibrary((HMODULE)DLL);
}

This worked for me:

Based off this TechNet Article:

https://technet.microsoft.com/en-us/library/ms144259(v=sql.90).aspx

I had the same issue. I just closed and reopened the terminal, and it worked. That was because I installed anaconda with the terminal open.

The h helper method:

<%=h "<p> will be preserved" %>

Moq version 4.8 (or later) has much improved support for by-ref parameters:

public interface IGobbler
{
    bool Gobble(ref int amount);
}

delegate void GobbleCallback(ref int amount);     // needed for Callback
delegate bool GobbleReturns(ref int amount);      // needed for Returns

var mock = new Mock<IGobbler>();
mock.Setup(m => m.Gobble(ref It.Ref<int>.IsAny))  // match any value passed by-ref
    .Callback(new GobbleCallback((ref int amount) =>
     {
         if (amount > 0)
         {
             Console.WriteLine("Gobbling...");
             amount -= 1;
         }
     }))
    .Returns(new GobbleReturns((ref int amount) => amount > 0));

int a = 5;
bool gobbleSomeMore = true;
while (gobbleSomeMore)
{
    gobbleSomeMore = mock.Object.Gobble(ref a);
}

The same pattern works for out parameters.

It.Ref<T>.IsAny also works for C# 7 in parameters (since they are also by-ref).

You would need to say which version of Ant and which JVM version.

You can run ant -v to see which settings Ant is using as per the doc

Ant 1.8* requires JDK 1.4 or higher.

The 'Unsupported major.minor version 51.0' means somewhere code was compiled for a version of the JDK, and that you are trying to run those classes under an older version of the JDK. (see here)

Looks like they have moved away from bitbucket and are now on github (https://github.com/pypa/setuptools)

Command to run is:

wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python

Your questions:

Q 1.) I would like to know why it returns all the texts that following the div?
It should not and I think in will not. It returns all div with 'id' attribute value equal 'containter' (and all children of this). But you are printing the results with ele.getText() Where getText will return all text content of all children of your result.

Get the visible (i.e. not hidden by CSS) innerText of this element, including sub-elements, without any leading or trailing whitespace.
Returns:
The innerText of this element.

Q 2.) how should I modify the code so it just return first or first few nodes that follow the parent note
This is not really clear what you are looking for. Example:

<p1> <div/> </p1 <p2/> 

The following to parent of the div is p2. This would be:

 //div[@id='container'][1]/parent::*/following-sibling::* 

or shorter

 //div[@id='container'][1]/../following-sibling::* 

If you are only looking for the first one extent the expression with an "predicate" (e.g [1] - for the first one. or [position() < 4]for the first three)

If your are looking for the first child of the first div:

//div[@id='container'][1]/*[1]

If there is only one div with id an you are looking for the first child:

   //div[@id='container']/*[1]

and so on.

If you look for POSIX compliant solution:

cd DirsRoot && find . -type f -print -o -name . -o -prune

-maxdepth is not POSIX compliant option.

The Standard Library provides an input function called ws, which consumes whitespace from an input stream. You can use it like this:

std::string s;
std::getline(std::cin >> std::ws, s);

Swift 5 extension:

extension UIImageView{
    func setImage(_ image: UIImage?, animated: Bool = true) {
        let duration = animated ? 0.3 : 0.0
        UIView.transition(with: self, duration: duration, options: .transitionCrossDissolve, animations: {
            self.image = image
        }, completion: nil)
    }
}
 

Use File.ReadAllText passing file location as an argument.

However, if your real goal is to parse html then I would recommend using Html Agility Pack.

Depending on what you want the file to contain:

• touch /path/to/file for an empty file

• somecommand > /path/to/file for a file containing the output of some command.

    eg: grep --help > randomtext.txt
        echo "This is some text" > randomtext.txt
  

• nano /path/to/file or vi /path/to/file (or any other editor emacs,gedit etc)
  It either opens the existing one for editing or creates & opens the empty file to enter, if it doesn't exist

Create the file using cat

$ cat > myfile.txt

Now, just type whatever you want in the file:

Hello World!

CTRL-D to save and exit

There are several possible solutions:

Create an empty file

touch file

>file

echo -n > file

printf '' > file

The echo version will work only if your version of echo supports the -n switch to suppress newlines. This is a non-standard addition. The other examples will all work in a POSIX shell.

Create a file containing a newline and nothing else

echo '' > file

printf '\n' > file

This is a valid "text file" because it ends in a newline.

Write text into a file

"$EDITOR" file

echo 'text' > file

cat > file <<END \
text
END

printf 'text\n' > file

These are equivalent. The $EDITOR command assumes that you have an interactive text editor defined in the EDITOR environment variable and that you interactively enter equivalent text. The cat version presumes a literal newline after the \ and after each other line. Other than that these will all work in a POSIX shell.

Of course there are many other methods of writing and creating files, too.

Simplest solution would be to use tool which allows you to directly specify ranges, like gnu shuf

shuf -i1-10 -n1

If you want to use $RANDOM, it would be more precise to throw out the last 8 numbers in 0...32767, and just treat it as 0...32759, since taking 0...32767 mod 10 you get the following distribution

0-8 each: 3277 
8-9 each: 3276

So, slightly slower but more precise would be

while :; do ran=$RANDOM; ((ran < 32760)) && echo $(((ran%10)+1)) && break; done 

i think it always boils to the classpath. having said that if you run from the same folder where your .class is then change Scanner input = new Scanner(new File("word.txt")); to Scanner input = new Scanner(new File("./word.txt")); that should work

Also add local account + rename computer at prompt + join to domain at promt

#Set A local admin account
$computername = $env:computername   # place computername here for remote access
$username = 'localadmin'
$password = 'P@ssw0rd1'
$desc = 'Local admin account'
$computer = [ADSI]"WinNT://$computername,computer"
$user = $computer.Create("user", $username)
$user.SetPassword($password)
$user.Setinfo()
$user.description = $desc
$user.setinfo()
$user.UserFlags = 65536
$user.SetInfo()
$group = [ADSI]("WinNT://$computername/administrators,group")
$group.add("WinNT://$username,user")

# Set computer name 
$computerName = Get-WmiObject Win32_ComputerSystem 
[System.Reflection.Assembly]::LoadWithPartialName('Microsoft.VisualBasic') | Out-Null 
$name = [Microsoft.VisualBasic.Interaction]::InputBox("Enter Desired Computer Name ")
$computername.rename("$name")

#Now Join to Domain
Add-Computer -DomainName [domainname] -Credential [user\domain]  -Verbose
Restart-Computer

Use genfromtxt instead. It's a much more general method than loadtxt:

import numpy as np
print np.genfromtxt('col.txt',dtype='str')

Using the file col.txt:

foo bar
cat dog
man wine

This gives:

[['foo' 'bar']
 ['cat' 'dog']
 ['man' 'wine']]

If you expect that each row has the same number of columns, read the first row and set the attribute filling_values to fix any missing rows.

The function time.NewTicker makes a channel that sends a periodic message, and provides a way to stop it. Use it something like this (untested):

ticker := time.NewTicker(5 * time.Second)
quit := make(chan struct{})
go func() {
    for {
       select {
        case <- ticker.C:
            // do stuff
        case <- quit:
            ticker.Stop()
            return
        }
    }
 }()

You can stop the worker by closing the quit channel: close(quit).

this.WindowState = FormWindowState.Maximized;

Easiest way to get the column names of the most recently executed SELECT is to use the cursor's description property. A Python example:

print_me = "("
for description in cursor.description:
    print_me += description[0] + ", "
print(print_me[0:-2] + ')')
# Example output: (inp, output, reason, cond_cnt, loop_likely)

git remote add origin <remote_repo_url>
git push --all origin

If you want to set all of your branches to automatically use this remote repo when you use git pull, add --set-upstream to the push:

git push --all --set-upstream origin

I imagine that trygetvalue is doing something more like:

if(myDict.ReallyOptimisedVersionofContains(someKey))
{ 
  someVal = myDict[someKey];
  return true;
}
return false;

So hopefully no try/catch anywhere.

I think it is just a method of convenience really. I generally use it as it saves a line of code or two.

If you are using Guava, you statically import newArrayList method from Lists class:

List<String> l = newArrayList(setOfAuthors);

Per the documentation:

And while the module doesn’t directly support parsing strings, it can easily be done:

import csv
for row in csv.reader(['one,two,three']):
    print row

Just turn your string into a single element list.

Importing StringIO seems a bit excessive to me when this example is explicitly in the docs.

The most popular option is to use some third party library distributed as npm package like ng2-bootstrap project https://github.com/valor-software/ng2-bootstrap or Angular UI Bootstrap library.

I personally use ng2-bootstrap. There are many ways to configure it, because configuration depends on how your Angular project is build. Underneath I post example configuration based on Angular 2 QuickStart project https://github.com/angular/quickstart

Firstly we add dependencies in our package.json

    { ...
"dependencies": {
    "@angular/common": "~2.4.0",
    "@angular/compiler": "~2.4.0",
    "@angular/core": "~2.4.0",

    ...

    "bootstrap": "^3.3.7",
    "ng2-bootstrap": "1.1.16-11"
  },
... }

Then we have to map names to proper URL's in systemjs.config.js

(function (global) {
  System.config({
    ...
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
      app: 'app',

      // angular bundles
      '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
      '@angular/common': 'npm:@angular/common/bundles/common.umd.js',
      '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
      '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
      '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
      '@angular/http': 'npm:@angular/http/bundles/http.umd.js',
      '@angular/router': 'npm:@angular/router/bundles/router.umd.js',
      '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',

      //bootstrap
      'moment': 'npm:moment/bundles/moment.umd.js',
      'ng2-bootstrap': 'npm:ng2-bootstrap/bundles/ng2-bootstrap.umd.js',

      // other libraries
      'rxjs':                      'npm:rxjs',
      'angular-in-memory-web-api': 'npm:angular-in-memory-web-api/bundles/in-memory-web-api.umd.js'
    },
...
  });
})(this);

We have to import bootstrap .css file in index.html. We can get it from /node_modules/bootstrap directory on our hard drive (because we added bootstrap 3.3.7 dependency) or from web. There we are obtaining it from web:

<!DOCTYPE html>
<html>
  <head>
    ...
    <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet">
    ...
  </head>

  <body>
    <my-app>Loading...</my-app>
  </body>
</html>

We should edit our app.module.ts file from /app directory

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

//bootstrap alert import part 1
import {AlertModule} from 'ng2-bootstrap';

import { AppComponent }  from './app.component';


@NgModule({
  //bootstrap alert import part 2
  imports:      [ BrowserModule, AlertModule.forRoot() ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

And finally our app.component.ts file from /app directory

import { Component } from '@angular/core';

@Component({
    selector: 'my-app',
    template: `
    <alert type="success">
        Well done!
    </alert>
    `
})

export class AppComponent {

    constructor() { }

}

Then we have to install our bootstrap and ng2-bootstrap dependencies before we run our app. We should go to our project directory and type

npm install

Finally we can start our app

npm start

There are many code samples on ng2-bootstrap project github showing how to import ng2-bootstrap to various Angular 2 project builds. There is even plnkr sample. There is also API documentation on Valor-software (authors of the library) website.

You have to give like this:

echo  $json_a['John']['status']; 

echo "<>"

echo  $json_a['Jennifer']['status'];

br inside <>

Which gives the result :

wait
active

You can use display:inline-block instead of float and vertical-align:middle with this CSS:

.col-lg-4, .col-lg-8 {
    float:none;
    display:inline-block;
    vertical-align:middle;
    margin-right:-4px;
}

Found the solution myself in the end. The problem was not with the LinearLayout, but with the ScrollView (seems weird, considering the fact that the ScrollView was expanding, while the LinearLayout wasn't).

The solution was to use android:fillViewport="true" on the ScrollView.

This worked for me in swift:

Create a subclass of UITableViewCell (make sure you link up your cell in the storyboard)

class MyTableCell:UITableViewCell{
    override func layoutSubviews() {
        super.layoutSubviews()

        if(self.imageView?.image != nil){

            let cellFrame = self.frame
            let textLabelFrame = self.textLabel?.frame
            let detailTextLabelFrame = self.detailTextLabel?.frame
            let imageViewFrame = self.imageView?.frame

            self.imageView?.contentMode = .ScaleAspectFill
            self.imageView?.clipsToBounds = true
            self.imageView?.frame = CGRectMake((imageViewFrame?.origin.x)!,(imageViewFrame?.origin.y)! + 1,40,40)
            self.textLabel!.frame = CGRectMake(50 + (imageViewFrame?.origin.x)! , (textLabelFrame?.origin.y)!, cellFrame.width-(70 + (imageViewFrame?.origin.x)!), textLabelFrame!.height)
            self.detailTextLabel!.frame = CGRectMake(50 + (imageViewFrame?.origin.x)!, (detailTextLabelFrame?.origin.y)!, cellFrame.width-(70 + (imageViewFrame?.origin.x)!), detailTextLabelFrame!.height)
        }
    }
}

In cellForRowAtIndexPath , dequeue the cell as your new cell type:

    let cell = tableView.dequeueReusableCellWithIdentifier("MyCell", forIndexPath: indexPath) as! MyTableCell

Obviously change number values to suit your layout

You need to implement RefreshTokenProvider. First create class for RefreshTokenProvider ie.

public class ApplicationRefreshTokenProvider : AuthenticationTokenProvider
{
    public override void Create(AuthenticationTokenCreateContext context)
    {
        // Expiration time in seconds
        int expire = 5*60;
        context.Ticket.Properties.ExpiresUtc = new DateTimeOffset(DateTime.Now.AddSeconds(expire));
        context.SetToken(context.SerializeTicket());
    }

    public override void Receive(AuthenticationTokenReceiveContext context)
    {
        context.DeserializeTicket(context.Token);
    }
}

Then add instance to OAuthOptions.

OAuthOptions = new OAuthAuthorizationServerOptions
{
    TokenEndpointPath = new PathString("/authenticate"),
    Provider = new ApplicationOAuthProvider(),
    AccessTokenExpireTimeSpan = TimeSpan.FromSeconds(expire),
    RefreshTokenProvider = new ApplicationRefreshTokenProvider()
};

An accrual ledger should note zeroes, even if that is the hyphen displayed with an Accounting style number format. However, if you want to leave the line blank when there are no values to calculate use a formula like the following,

 =IF(COUNT(F16:G16), SUM(G16, INDEX(H$1:H15, MATCH(1e99, H$1:H15)), -F16), "")

That formula is a little tricky because you seem to have provided your sample formula from somewhere down into the entries of the ledger's item rows without showing any layout or sample data. The formula I provided should be able to be put into H16 and then copied or filled to other locations in column H but I offer no guarantees without seeing the layout.

If you post some sample data or a publicly available link to a screenshot showing your data layout more specific assistance could be offered. http://imgur.com/ is a good place to host a screenshot and it is likely that someone with more reputation will insert the image into your question for you.

I solve it putting a "p" tag inside of my "td" tag like this:

<td><p class="">This is my loooooooong paragraph</p></td>

Then add this properties to the class, using max-width to define how wide you want your field to be

.p-wrap {
  max-width: 400px;
  word-wrap: break-word;
  white-space: pre-wrap;
  font-size: 12px;
}

I had similar problem extracting certificates from a file. This might not be the most best way to do it but it worked for me.

openssl pkcs7 -inform DER -print_certs -in <path of the file> | awk 'split_after==1{n++;split_after=0} /-----END CERTIFICATE-----/ {split_after=1} {print > "cert" n ".pem"}'

Just for completion, the best solution here is often to require a factory function argument:

T GetObject<T>(Func<T> factory)
{  return factory(); }

and call it something like this:

string s = GetObject(() => "result");

You can use that to require or make use of available parameters, if needed.

On the same note - VS 2015, .vs\config\applicationhost.config not visible or not available.

By default .vs folder is hidden (at least in my case).

If you are not able to find the .vs folder, follow the below steps.

1. Right click on the Solution folder
2. select 'Properties'
3. In Attributes section, click Hidden check box(default unchecked),
4. then click the 'Apply' button
5. It will show up confirmation window 'Apply changes to this folder, subfolder and files' option selected, hit 'Ok'.
   
   Repeat step 1 to 5, except on step 3, this time you need to uncheck the 'Hidden' option that you checked previously.

Now should be able to see .vs folder.

After returning from a function, all identifiers are destroyed instead of kept values in a memory location and we can not locate the values without having an identifier.But that location still contains the value stored by previous function.

So, here function foo() is returning the address of a and a is destroyed after returning its address. And you can access the modified value through that returned address.

Let me take a real world example:

Suppose a man hides money at a location and tells you the location. After some time, the man who had told you the money location dies. But still you have the access of that hidden money.

You forgot to close the Class bracket.

This article on CodeProject "An INI file handling class using C#" should help.

The author created a C# class "Ini" which exposes two functions from KERNEL32.dll. These functions are: WritePrivateProfileString and GetPrivateProfileString. You will need two namespaces: System.Runtime.InteropServices and System.Text.

Steps to use the Ini class

In your project namespace definition add

using INI;

Create a INIFile like this

INIFile ini = new INIFile("C:\\test.ini");

Use IniWriteValue to write a new value to a specific key in a section or use IniReadValue to read a value FROM a key in a specific Section.

Note: if you're beginning from scratch, you could read this MSDN article: How to: Add Application Configuration Files to C# Projects. It's a better way for configuring your application.

I have never done so, but it seems like

MATCH (head, head, body) AGAINST ('some words' IN BOOLEAN MODE)

Should give a double weight to matches found in the head.

Just read this comment on the docs page, Thought it might be of value to you:

Posted by Patrick O'Lone on December 9 2002 6:51am

It should be noted in the documentation that IN BOOLEAN MODE will almost always return a relevance of 1.0. In order to get a relevance that is meaningful, you'll need to:

SELECT MATCH('Content') AGAINST ('keyword1 keyword2') as Relevance 
FROM table 
WHERE MATCH ('Content') AGAINST('+keyword1+keyword2' IN BOOLEAN MODE) 
HAVING Relevance > 0.2 
ORDER BY Relevance DESC 

Notice that you are doing a regular relevance query to obtain relevance factors combined with a WHERE clause that uses BOOLEAN MODE. The BOOLEAN MODE gives you the subset that fulfills the requirements of the BOOLEAN search, the relevance query fulfills the relevance factor, and the HAVING clause (in this case) ensures that the document is relevant to the search (i.e. documents that score less than 0.2 are considered irrelevant). This also allows you to order by relevance.

This may or may not be a bug in the way that IN BOOLEAN MODE operates, although the comments I've read on the mailing list suggest that IN BOOLEAN MODE's relevance ranking is not very complicated, thus lending itself poorly for actually providing relevant documents. BTW - I didn't notice a performance loss for doing this, since it appears MySQL only performs the FULLTEXT search once, even though the two MATCH clauses are different. Use EXPLAIN to prove this.

So it would seem you may not need to worry about calling the fulltext search twice, though you still should "use EXPLAIN to prove this"

<img id="output_image" height=50px width=50px\
<input type="file" accept="image/*" onchange="preview_image(event)">

<script type"text/javascript">
  function preview_image(event) {
    var reader = new FileReader();
    reader.onload = function(){
      var output = document.getElementById('output_image');
      output.src = reader.result;
    }
    reader.readAsDataURL(event.target.files[0]);

You should try this. It starts the program with no window. It actually flashes up for a second but goes away fairly quickly.

start "name" /B myprogram.exe param1

I know this is a late answer but you could manually change the 7 font declarations in the latest version of Bootstrap:

html {
  font-family: sans-serif;
}

body {
  font-family: sans-serif;
}

pre, code, kbd, samp {
  font-family: monospace;
}

input, button, select, optgroup, textarea {
  font-family: inherit;
}

.tooltip {
  font-family: sans-serif;
}

.popover {
  font-family: sans-serif;
}

.text-monospace {
  font-family: monospace;
}

Good luck.

I figured out how to do this with InjectionTokens (see example below), and if your project was built using the Angular CLI you can use the environment files found in /environments for static application wide settings like an API endpoint, but depending on your project's requirements you will most likely end up using both since environment files are just object literals, while an injectable configuration using InjectionToken's can use the environment variables and since it's a class can have logic applied to configure it based on other factors in the application, such as initial http request data, subdomain, etc.

Injection Tokens Example

/app/app-config.module.ts

import { NgModule, InjectionToken } from '@angular/core';
import { environment } from '../environments/environment';

export let APP_CONFIG = new InjectionToken<AppConfig>('app.config');

export class AppConfig {
  apiEndpoint: string;
}

export const APP_DI_CONFIG: AppConfig = {
  apiEndpoint: environment.apiEndpoint
};

@NgModule({
  providers: [{
    provide: APP_CONFIG,
    useValue: APP_DI_CONFIG
  }]
})
export class AppConfigModule { }

/app/app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { AppConfigModule } from './app-config.module';

@NgModule({
  declarations: [
    // ...
  ],
  imports: [
    // ...
    AppConfigModule
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

Now you can just DI it into any component, service, etc:

/app/core/auth.service.ts

import { Injectable, Inject } from '@angular/core';
import { Http, Response } from '@angular/http';
import { Router } from '@angular/router';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';
import 'rxjs/add/observable/throw';

import { APP_CONFIG, AppConfig } from '../app-config.module';
import { AuthHttp } from 'angular2-jwt';

@Injectable()
export class AuthService {

  constructor(
    private http: Http,
    private router: Router,
    private authHttp: AuthHttp,
    @Inject(APP_CONFIG) private config: AppConfig
  ) { }

  /**
   * Logs a user into the application.
   * @param payload
   */
  public login(payload: { username: string, password: string }) {
    return this.http
      .post(`${this.config.apiEndpoint}/login`, payload)
      .map((response: Response) => {
        const token = response.json().token;
        sessionStorage.setItem('token', token); // TODO: can this be done else where? interceptor
        return this.handleResponse(response); // TODO:  unset token shouldn't return the token to login
      })
      .catch(this.handleError);
  }

  // ...
}

You can then also type check the config using the exported AppConfig.

You should definitely encapsulate this logic into a method.

There is no benefit to repeating identical code multiple times.

Also, if you place the logic in a method and it changes, you only need to modify your code in one place.

Whether or not you want to use a 3rd party library is an entirely different decision.

Array Filter method

var arr = [1, 2, 3]_x000D_
_x000D_
// ES5 syntax_x000D_
arr = arr.filter(function(item){ return item != 3 })_x000D_
_x000D_
// ES2015 syntax_x000D_
arr = arr.filter(item => item != 3)_x000D_
_x000D_
console.log( arr )

this is just a shot in the dark : when you call connect without a bind first, the system allocates your local port, and if you have multiple threads connecting and disconnecting it could possibly try to allocate a port already in use. the kernel source file inet_connection_sock.c hints at this condition. just as an experiment try doing a bind to a local port first, making sure each bind/connect uses a different local port number.

Python has docstrings and ruby doesn't... Or if it doesn't, they are not accessible as easily as in python.

Ps. If im wrong, pretty please, leave an example? I have a workaround that i could monkeypatch into classes quite easily but i'd like to have docstring kinda of a feature in "native way".

@Ludwig 's solution was brilliant. A couple of fixes (which didn't have to do with operating system, and I couldn't place as a comment on his original posting because this is too long):

1. IE 11 no longer identifies itself as MS IE.
2. Chrome on IOS spoofs itself as Safari

You could add a method to String to make it more semantic:

String.metaClass.getNotBlank = { !delegate.allWhitespace }

which let's you do:

groovy:000> foo = ''
===> 
groovy:000> foo.notBlank
===> false
groovy:000> foo = 'foo'
===> foo
groovy:000> foo.notBlank
===> true

It means that the query you wrote returns more than one element(result) while your code expects a single result.

The first thing you should know is most of the locale config file located path can be get from localedef --help :

$ localedef --help | tail -n 5
System's directory for character maps : /usr/share/i18n/charmaps
                       repertoire maps: /usr/share/i18n/repertoiremaps
                       locale path    : /usr/lib/locale:/usr/share/i18n
For bug reporting instructions, please see:
<https://bugs.launchpad.net/ubuntu/+source/glibc/+bugs>

See the last /usr/share/i18n ? This is where your xx_XX.UTF-8 config file located:

$ ls /usr/share/i18n/locales/zh_*
/usr/share/i18n/locales/zh_CN  /usr/share/i18n/locales/zh_HK  /usr/share/i18n/locales/zh_SG  /usr/share/i18n/locales/zh_TW

Now what ? We need to compile them into archive binary. One of the way, e.g. assume I have /usr/share/i18n/locales/en_LOVE, I can add it into compile list, i.e. /etc/locale-gen file:

$ tail -1 /etc/locale.gen 
en_LOVE.UTF-8 UTF-8

And compile it to binary with sudo locale-gen:

$ sudo locale-gen 
Generating locales (this might take a while)...
  en_AG.UTF-8... done
  en_AU.UTF-8... done
  en_BW.UTF-8... done
  ...
  en_LOVE.UTF-8... done
Generation complete.

And now update the system default locale with desired LANG, LC_ALL ...etc with this update-locale:

sudo update-locale LANG=en_LOVE.UTF-8

update-locale actually also means to update this /etc/default/locale file which will source by system on login to setup environment variables:

$ head /etc/default/locale 
#  File generated by update-locale
LANG=en_LOVE.UTF-8
LC_NUMERIC="en_US.UTF-8"
...

But we may not want to reboot to take effect, so we can just source it to environment variable in current shell session:

$ . /etc/default/locale

How about sudo dpkg-reconfigure locales ? If you play around it you will know this command basically act as GUI to simplify the above steps, i.e. Edit /etc/locale.gen -> sudo locale-gen -> sudo update-locale LANG=en_LOVE.UTF-8

For python, as long as /etc/locale.gen contains that locale candidate and locale.gen get compiled, setlocale(category, locale) should work without throws locale.Error: unsupoorted locale setting. You can check the correct string en_US.UTF-8/en_US/....etc to be set in setlocale(), by observing /etc/locale.gen file, and then uncomment and compile it as desired. zh_CN GB2312 without dot in that file means the correct string is zh_CN and zh_CN.GB2312.

I came across another solution here that is so simple: add padding-right to the textarea's container. This keeps the margin, border, and padding on the textarea, which avoids the problem that Beck pointed out about the focus highlight that chrome and safari put around the textarea.

The container's padding-right should be the sum of the effective margin, border, and padding on both sides of the textarea, plus any padding you may otherwise want for the container. So, for the case in the original question:

textarea{
    border:1px solid #999999;
    width:100%;
    margin:5px 0;
    padding:3px;
}
.textareacontainer{
    padding-right: 8px; /* 1 + 3 + 3 + 1 */
}

<div class="textareacontainer">
    <textarea></textarea>
</div>

Are you using qmake projects? If so, you can add an external library using the LIBS variable. E.g:

win32:LIBS += path/to/Psapi.lib

The name of the spyder executable was changed to spyder3.exe in python version 3. I install pyqt5 and spyder via pip and was able to launch spyder3. I first tried without installing pyqt5 and nothing happened. Once I installed pyqt5, then spyder 3 opened.

Try the following from a windows cmd.exe prompt:

    C:\Users\..>pip install pyqt5
    C:\Users\..>pip install spyder
    C:\Users\..>spyder3

I have to quote Jon (the master of c#) Skeet:

Well, the easiest way would be to open a file stream and then use:

byte[] data = memoryStream.ToArray(); fileStream.Write(data, 0, data.Length);

That's relatively inefficient though, as it involves copying the buffer. It's fine for small streams, but for huge amounts of data you should consider using:

fileStream.Write(memoryStream.GetBuffer(), 0, memoryStream.Position);

I use the InvokeOnClick() method. It takes two arguments: Control and EventArgs. If you need the EventArgs, then create an instance of it and pass it in, else use InvokeOnClick(controlToClick, null);. You can use a variety of Mouse event related arguments that derive from EventArgs such as MouseEventArgs.

    }

    public void AddSeconds(uint s)
    {
        this.Seconds += (int)s;
        while(this.Seconds > 59)

There is also at least one library for doing native threading from within Node.js: node-webworker-threads

https://github.com/audreyt/node-webworker-threads

This basically implements the Web Worker browser API for node.js.

Simple way without using Regex:

Adding an extra character check for dot '.' will solve the requirement:

public static String getOnlyNumerics(String str) {
    if (str == null) {
        return null;
    }
    StringBuffer strBuff = new StringBuffer();
    char c;
    for (int i = 0; i < str.length() ; i++) {
        c = str.charAt(i);
        if (Character.isDigit(c) || c == '.') {
            strBuff.append(c);
        }
    }
    return strBuff.toString();
}

It's possible that you've run out of memory or some space elsewhere and it prompted the system to mount an overflow filesystem, and for whatever reason, it's not going away.

Try unmounting the overflow partition:

umount /tmp

or

umount overflow

For static declaration I think you could use:

T myarray[100] = {0};

For dynamic declaration I suggest the same way: memset

If others who view this question only have a JSON string (not in an object), then you can put it into a HashMap and still get the ObjectMapper to work. The result variable is your JSON string.

import com.fasterxml.jackson.core.JsonParseException;
import com.fasterxml.jackson.databind.JsonMappingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import java.util.HashMap;
import java.util.Map;

// Pretty-print the JSON result
try {
    ObjectMapper objectMapper = new ObjectMapper();
    Map<String, Object> response = objectMapper.readValue(result, HashMap.class);
    System.out.println(objectMapper.writerWithDefaultPrettyPrinter().writeValueAsString(response));
} catch (JsonParseException e) {
    e.printStackTrace();
} catch (JsonMappingException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
} 

The first case is telling the web server that you are posting JSON data as in:

{ Name : 'John Smith', Age: 23}

The second option is telling the web server that you will be encoding the parameters in the URL as in:

Name=John+Smith&Age=23

SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA='SCHEMA_NAME' AND COLUMN_KEY='PRI'; WHERE COLUMN_KEY='PRI';

The linux.org reference page explains the mechanics, but doesn't explain any of the motivation behind it :-(

For that, see Sun Linker and Libraries Guide

In addition, note that "external versioning" is largely obsolete on Linux, because symbol versioning (a GNU extension) allows you to have multiple incompatible versions of the same function to be present in a single library. This extension allowed glibc to have the same external version: libc.so.6 for the last 10 years.

this will prevent any zoom action by the user in ios safari and also prevent the "zoom to tabs" feature:

document.addEventListener('gesturestart', function(e) {
    e.preventDefault();
    // special hack to prevent zoom-to-tabs gesture in safari
    document.body.style.zoom = 0.99;
});

document.addEventListener('gesturechange', function(e) {
    e.preventDefault();
    // special hack to prevent zoom-to-tabs gesture in safari
    document.body.style.zoom = 0.99;
});

document.addEventListener('gestureend', function(e) {
    e.preventDefault();
    // special hack to prevent zoom-to-tabs gesture in safari
    document.body.style.zoom = 0.99;
});

You should be able to simply do this:

Context context = new InitialContext();
dataSource = (javax.sql.DataSource) context.lookup("jdbc/myDataSource");

If you are looking it up from a remote destination you need to use the WL initial context factory like this:

Hashtable<String, String> h = new Hashtable<String, String>(7);
h.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
h.put(Context.PROVIDER_URL, pURL); //For example "t3://127.0.0.1:7001"
h.put(Context.SECURITY_PRINCIPAL, pUsername);
h.put(Context.SECURITY_CREDENTIALS, pPassword);

InitialContext context = new InitialContext(h);
dataSource = (javax.sql.DataSource) context.lookup("jdbc/myDataSource");

weblogic.jndi.WLInitialContextFactory

private void PostForm()
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://dork.com/service");
    request.Method = "POST";
    request.ContentType = "application/x-www-form-urlencoded";
    string postData ="home=Cosby&favorite+flavor=flies";
    byte[] bytes = Encoding.UTF8.GetBytes(postData);
    request.ContentLength = bytes.Length;

    Stream requestStream = request.GetRequestStream();
    requestStream.Write(bytes, 0, bytes.Length);

    WebResponse response = request.GetResponse();
    Stream stream = response.GetResponseStream();
    StreamReader reader = new StreamReader(stream);

    var result = reader.ReadToEnd();
    stream.Dispose();
    reader.Dispose();
}

First of all convert your set to Array. Then, get item by index of array .

Set uniqueItem = new HashSet() ;
uniqueItem.add("0");
uniqueItem.add("1");
uniqueItem.add("0");

Object[] arrayItem = uniqueItem.toArray(); 
for(int i = 0; i < uniqueItem.size();i++){
    System.out.println("Item "+i+" "+arrayItem[i].toString());
}

You cannot use a variable in a create table statement. The best thing I can suggest is to write the entire query as a string and exec that.

Try something like this:

declare @query varchar(max);
set @query = 'create database TEST...';

exec (@query);

From the "View" menu, select "Workspaces". You'll see all of the workspaces you've created. Select the workspaces you want to delete and click "Edit" -> "Delete Workspace", or right-click and select "Delete Workspace". If the workspace is "locked" to prevent changes, you'll get an error message.

To unlock the workspace, click "Edit" (or right-click and click "Edit Workspace") to pull up the workspace editor, uncheck the "locked" checkbox, and save your changes. You can delete the workspace once it's unlocked.

In my experience, the workspace will continue to be shown in the drop-down list until you click on it, at which point p4v will figure out you've deleted it and remove it from the list.

Even better use implicit remoting to use a module from another Machine!

$s = New-PSSession Server-Name
Invoke-Command -Session $s -ScriptBlock {Import-Module ActiveDirectory}
Import-PSSession -Session $s -Module ActiveDirectory -Prefix REM

This will allow you to use the module off a remote PC for as long as the PSSession is connected.

Simply pass the BSTR directly to the wstring constructor, it is compatible with a wchar_t*:

BSTR btest = SysAllocString(L"Test");
assert(btest != NULL);
std::wstring wtest(btest);
assert(0 == wcscmp(wtest.c_str(), btest));

Converting BSTR to std::string requires a conversion to char* first. That's lossy since BSTR stores a utf-16 encoded Unicode string. Unless you want to encode in utf-8. You'll find helper methods to do this, as well as manipulate the resulting string, in the ICU library.

Here is some code from above added with actual action code (point 1 and 2);

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let deleteAction = UIContextualAction(style: .destructive, title: "Delete") { _, _, completionHandler in

        // 2. reload the table, otherwise you get an index out of bounds crash
        self.tableView.reloadData()

        completionHandler(true)
    }
    deleteAction.backgroundColor = .systemOrange
    let configuration = UISwipeActionsConfiguration(actions: [deleteAction])
    configuration.performsFirstActionWithFullSwipe = true

Looking at this official google link: Youtube Live encoder settings, bitrates and resolutions they have this table:

                   240p       360p        480p        720p        1080p
Resolution      426 x 240   640 x 360   854x480     1280x720    1920x1080
Video Bitrates                   
Maximum         700 Kbps    1000 Kbps   2000 Kbps   4000 Kbps   6000 Kbps
Recommended     400 Kbps    750 Kbps    1000 Kbps   2500 Kbps   4500 Kbps
Minimum         300 Kbps    400 Kbps    500 Kbps    1500 Kbps   3000 Kbps

It would appear as though this is the case, although the numbers dont sync up to the google table above:

// the bitrates, video width and file names for this clip
      bitrates: [
        { url: "bbb-800.mp4", width: 480, bitrate: 800 }, //360p video
        { url: "bbb-1200.mp4", width: 720, bitrate: 1200 }, //480p video
        { url: "bbb-1600.mp4", width: 1080, bitrate: 1600 } //720p video
      ],

You'll likely need to check the SQL Server error logs to determine the actual state (it's not reported to the client for security reasons.) See here for details.

It sounds like you might need to create and query linked database servers in SQL Server

At the moment you've created a query that's going between different databases using a 3 part name mydatabase.dbo.mytable but you need to go up a level and use a 4 part name myserver.mydatabase.dbo.mytable, see this post on four part naming for more info

edit
The four part naming for your existing query would be as shown below (which I suspect you may have already tried?), but this assumes you can "get to" the remote database with the four part name, you might need to edit your host file / register the server or otherwise identify where to find database.windows.net.

INSERT INTO [DATABASE.WINDOWS.NET].[basecampdev].[dbo].[invoice]
       ([InvoiceNumber]
       ,[TotalAmount]
       ,[IsActive]
       ,[CreatedBy]
       ,[UpdatedBy]
       ,[CreatedDate]
       ,[UpdatedDate]
       ,[Remarks])
SELECT [InvoiceNumber]
       ,[TotalAmount]
       ,[IsActive]
       ,[CreatedBy]
       ,[UpdatedBy]
       ,[CreatedDate]
       ,[UpdatedDate]
       ,[Remarks] FROM [BC1-PC].[testdabse].[dbo].[invoice]

If you can't access the remote server then see if you can create a linked database server:

EXEC sp_addlinkedserver [database.windows.net];
GO
USE tempdb;
GO
CREATE SYNONYM MyInvoice FOR 
    [database.windows.net].basecampdev.dbo.invoice;
GO

Then you can just query against MyEmployee without needing the full four part name

In Bluetooth, all objects are identified by UUIDs. These include services, characteristics and many other things. Bluetooth maintains a database of assigned numbers for standard objects, and assigns sub-ranges for vendors (that have paid enough for a reservation). You can view this list here:

https://www.bluetooth.com/specifications/assigned-numbers/

If you are implementing a standard service (e.g. a serial port, keyboard, headset, etc.) then you should use that service's standard UUID - that will allow you to be interoperable with devices that you didn't develop.

If you are implementing a custom service, then you should generate unique UUIDs, in order to make sure incompatible third-party devices don't try to use your service thinking it is something else. The easiest way is to generate random ones and then hard-code the result in your application (and use the same UUIDs in the devices that will connect to your service, of course).

I used encoding filter which has solved my all encoding problem...

    public class EncodingFilter implements Filter {

        private String encoding = "utf-8";

        public void doFilter(ServletRequest request,ServletResponse response, FilterChain filterChain) throws IOException, ServletException {
            request.setCharacterEncoding(encoding);
    //                response.setContentType("text/html;charset=UTF-8");
                    response.setCharacterEncoding(encoding);
            filterChain.doFilter(request, response);

        }

        public void init(FilterConfig filterConfig) throws ServletException {
            String encodingParam = filterConfig.getInitParameter("encoding");
            if (encodingParam != null) {
                encoding = encodingParam;
            }
        }

        public void destroy() {

Yes you can do it yourself. It is just a matter of grabbing the sources of the page and parsing them the way you want.

There are various possibilities. A good combo is using python-requests (built on top of urllib2, it is urllib.request in Python3) and BeautifulSoup4, which has its methods to select elements and also permits CSS selectors:

import requests
from BeautifulSoup4 import BeautifulSoup as bs
request = requests.get("http://foo.bar")
soup = bs(request.text) 
some_elements = soup.find_all("div", class_="myCssClass")

Some will prefer xpath parsing or jquery-like pyquery, lxml or something else.

When the data you want is produced by some JavaScript, the above won't work. You either need python-ghost or Selenium. I prefer the latter combined with PhantomJS, much lighter and simpler to install, and easy to use:

from selenium import webdriver
client = webdriver.PhantomJS()
client.get("http://foo")
soup = bs(client.page_source)

I would advice to start your own solution. You'll understand Scrapy's benefits doing so.

ps: take a look at scrapely: https://github.com/scrapy/scrapely

pps: take a look at Portia, to start extracting information visually, without programming knowledge: https://github.com/scrapinghub/portia

I usually loop over the array and attach a comma after every entry in the string. After the loop I delete the last comma again.

Maybe not the best way, but less expensive than checking every time if it's the last object in the loop I guess.

Set $JAVA_HOME environment variable on latest or older Mac OSX.

Download & Install install JDK

1. First, install JDK
2. Open terminal check java version

$ java -version

Set JAVA_HOME environment variable

1. Open .zprofile file

$ open -t .zprofile

Or create . zprofile file

$ open -t .zprofile

2. write in .zprofile

export JAVA_HOME=$(/usr/libexec/java_home)

Save .zprofile and close the bash file & then write in the terminal for work perfectly.

$ source .zprofile

Setup test in terminal

$ echo $JAVA_HOME  
/Library/Java/JavaVirtualMachines/jdk-13.0.1.jdk/Contents/Home

CATALINA_HOME vs CATALINA_BASE

If you're running multiple instances, then you need both variables, otherwise only CATALINA_HOME.

In other words: CATALINA_HOME is required and CATALINA_BASE is optional.

CATALINA_HOME represents the root of your Tomcat installation.

Optionally, Tomcat may be configured for multiple instances by defining $CATALINA_BASE for each instance. If multiple instances are not configured, $CATALINA_BASE is the same as $CATALINA_HOME.

See: Apache Tomcat 7 - Introduction

Running with separate CATALINA_HOME and CATALINA_BASE is documented in RUNNING.txt which say:

The CATALINA_HOME and CATALINA_BASE environment variables are used to specify the location of Apache Tomcat and the location of its active configuration, respectively.

You cannot configure CATALINA_HOME and CATALINA_BASE variables in the setenv script, because they are used to find that file.

For example:

(4.1) Tomcat can be started by executing one of the following commands:

  %CATALINA_HOME%\bin\startup.bat         (Windows)

  $CATALINA_HOME/bin/startup.sh           (Unix)

or

  %CATALINA_HOME%\bin\catalina.bat start  (Windows)

  $CATALINA_HOME/bin/catalina.sh start    (Unix)

Multiple Tomcat Instances

In many circumstances, it is desirable to have a single copy of a Tomcat binary distribution shared among multiple users on the same server. To make this possible, you can set the CATALINA_BASE environment variable to the directory that contains the files for your 'personal' Tomcat instance.

When running with a separate CATALINA_HOME and CATALINA_BASE, the files and directories are split as following:

In CATALINA_BASE:

• bin - Only: setenv.sh (*nix) or setenv.bat (Windows), tomcat-juli.jar
• conf - Server configuration files (including server.xml)
• lib - Libraries and classes, as explained below
• logs - Log and output files
• webapps - Automatically loaded web applications
• work - Temporary working directories for web applications
• temp - Directory used by the JVM for temporary files>

In CATALINA_HOME:

• bin - Startup and shutdown scripts
• lib - Libraries and classes, as explained below
• endorsed - Libraries that override standard "Endorsed Standards". By default it's absent.

How to check

The easiest way to check what's your CATALINA_BASE and CATALINA_HOME is by running startup.sh, for example:

$ /usr/share/tomcat7/bin/startup.sh
Using CATALINA_BASE:   /usr/share/tomcat7
Using CATALINA_HOME:   /usr/share/tomcat7

You may also check where the Tomcat files are installed, by dpkg tool as below (Debian/Ubuntu):

dpkg -L tomcat7-common

function get_col_names(){  
    $sql = "SHOW COLUMNS FROM tableName";  
    $result = mysql_query($sql);     
    while($record = mysql_fetch_array($result)){  
     $fields[] = $record['0'];  
    }
    foreach ($fields as $value){  
      echo 'column name is : '.$value.'-';  
}  
 }  

return get_col_names();

getSupportFragmentManager() used when you are in activity and want to get a fragment but in the fragment you can access

getSupportFragmentManager()

by use another method called getFragmentMangaer() works the same like getSupportFragmentManager() and you can use it like you used to:

fragmentTransaction =getFragmentManager().beginTransaction();

If you use divmod, you are immune to different flavors of integer division:

# show time strings for 3800 seconds

# easy way to get mm:ss
print "%02d:%02d" % divmod(3800, 60)

# easy way to get hh:mm:ss
print "%02d:%02d:%02d" % \
    reduce(lambda ll,b : divmod(ll[0],b) + ll[1:],
        [(3800,),60,60])


# function to convert floating point number of seconds to
# hh:mm:ss.sss
def secondsToStr(t):
    return "%02d:%02d:%02d.%03d" % \
        reduce(lambda ll,b : divmod(ll[0],b) + ll[1:],
            [(round(t*1000),),1000,60,60])

print secondsToStr(3800.123)

Prints:

63:20
01:03:20
01:03:20.123

The problem with your solution is you're putting a scrollbar around a ListBox where you probably want to put it inside the ListBox.

If you want to force a scrollbar in your ListBox, use the ScrollBar.VerticalScrollBarVisibility attached property.

<ListBox 
    ItemsSource="{Binding}" 
    ScrollViewer.VerticalScrollBarVisibility="Visible">
</ListBox>

Setting this value to Auto will popup the scrollbar on an as needed basis.

Although, I'm a big fan of Kanban Tool service (it has everything you need except free of charge) and therefore it's difficult for me to stay objective, I think that should go for Trello or Kanban Flow. Both are free and both provide basic features that are essential for agile process managers and their teams.

Better to return HttpResponseMessage with StreamContent inside of it.

Here is example:

public HttpResponseMessage GetFile(string id)
{
    if (String.IsNullOrEmpty(id))
        return Request.CreateResponse(HttpStatusCode.BadRequest);

    string fileName;
    string localFilePath;
    int fileSize;

    localFilePath = getFileFromID(id, out fileName, out fileSize);

    HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.OK);
    response.Content = new StreamContent(new FileStream(localFilePath, FileMode.Open, FileAccess.Read));
    response.Content.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment");
    response.Content.Headers.ContentDisposition.FileName = fileName;
    response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/pdf");

    return response;
}

UPD from comment by patridge: Should anyone else get here looking to send out a response from a byte array instead of an actual file, you're going to want to use new ByteArrayContent(someData) instead of StreamContent (see here).

Your code scope (this) will be your window object, not your react component, and that is why setTimeout(this.setState({position: 1}), 3000) will crash this way.

That comes from javascript not React, it is js closure

So, in order to bind your current react component scope, do this:

setTimeout(function(){this.setState({position: 1})}.bind(this), 3000);

Or if your browser supports es6 or your projs has support to compile es6 to es5, try arrow function as well, as arrow func is to fix 'this' issue:

setTimeout(()=>this.setState({position: 1}), 3000);

The XMLHttpRequest.timeout property represents a number of milliseconds a request can take before automatically being terminated. The default value is 0, which means there is no timeout. An important note the timeout shouldn't be used for synchronous XMLHttpRequests requests, used in a document environment or it will throw an InvalidAccessError exception. You may not use a timeout for synchronous requests with an owning window.

IE10 and 11 do not support synchronous requests, with support being phased out in other browsers too. This is due to detrimental effects resulting from making them.

More info can be found here.

If you wish to see if there is any duplicate rows in your table, I used below Query:

create table my_table(id int, name varchar(100), email varchar(100));

insert into my_table values (1, 'shekh', '[email protected]');
insert into my_table values (1, 'shekh', '[email protected]');
insert into my_table values (2, 'Aman', '[email protected]');
insert into my_table values (3, 'Tom', '[email protected]');
insert into my_table values (4, 'Raj', '[email protected]');


Select COUNT(1) As Total_Rows from my_table 
Select Count(1) As Distinct_Rows from ( Select Distinct * from my_table) abc 

In your case, the error is that you're trying to generate an Error instance. Error in Swift 3 is a protocol that can be used to define a custom error. This feature is especially for pure Swift applications to run on different OS.

In iOS development the NSError class is still available and it conforms to Error protocol.

So, if your purpose is only to propagate this error code, you can easily replace

var errorTemp = Error(domain:"", code:httpResponse.statusCode, userInfo:nil)

with

var errorTemp = NSError(domain:"", code:httpResponse.statusCode, userInfo:nil)

Otherwise check the Sandeep Bhandari's answer regarding how to create a custom error type

The problem is hard to implement if the input data is too large (say millions of strings). I used elastic search to solve this.

Quick start : https://www.elastic.co/guide/en/elasticsearch/client/net-api/6.x/elasticsearch-net.html

Just insert all the input data into DB and you can search any string based on any edit distance quickly. Here is a C# snippet which will give you a list of results sorted by edit distance (smaller to higher)

var res = client.Search<ClassName>(s => s
    .Query(q => q
    .Match(m => m
        .Field(f => f.VariableName)
        .Query("SAMPLE QUERY")
        .Fuzziness(Fuzziness.EditDistance(5))
    )
));

Or you could just pass a string of delimited items and put it into an array or list on the receiving end.

Following is the code that i used to have black border. Note that i have not used extra xml file for border.

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/red_minus_icon"
    android:background="#000000"
    android:padding="1dp"/>

If you are using Visual Studio, there is a GUI solution as well:

1. From Toolbox add a ContextMenuStrip
2. Select the context menu and add the right click items
3. For each item set the click events to the corresponding functions
4. Select the form / button / image / etc (any item) that the right click menu will be connected
5. Set its ContextMenuStrip property to the menu you have created.

In the parent table, try setting

border-collapse:separate; 
border-spacing:5em;

Plus a border declaration, and see if this achieves your desired effect. Beware, though, that IE doesn't support the "separated borders" model.

This script will resize an image (somepic.jpg) using PIL (Python Imaging Library) to a width of 300 pixels and a height proportional to the new width. It does this by determining what percentage 300 pixels is of the original width (img.size[0]) and then multiplying the original height (img.size[1]) by that percentage. Change "basewidth" to any other number to change the default width of your images.

from PIL import Image

basewidth = 300
img = Image.open('somepic.jpg')
wpercent = (basewidth/float(img.size[0]))
hsize = int((float(img.size[1])*float(wpercent)))
img = img.resize((basewidth,hsize), Image.ANTIALIAS)
img.save('somepic.jpg')

nltk have its pre-trained tokenizer models. Model is downloading from internally predefined web sources and stored at path of installed nltk package while executing following possible function calls.

E.g. 1 tokenizer = nltk.data.load('nltk:tokenizers/punkt/english.pickle')

E.g. 2 nltk.download('punkt')

If you call above sentence in your code, Make sure you have internet connection without any firewall protections.

I would like to share some more better alter-net way to resolve above issue with more better deep understandings.

Please follow following steps and enjoy english word tokenization using nltk.

Step 1: First download the "english.pickle" model following web path.

Goto link "http://www.nltk.org/nltk_data/" and click on "download" at option "107. Punkt Tokenizer Models"

Step 2: Extract the downloaded "punkt.zip" file and find the "english.pickle" file from it and place in C drive.

Step 3: copy paste following code and execute.

from nltk.data import load
from nltk.tokenize.treebank import TreebankWordTokenizer

C:\Users\<_username>\.gradle\wrapper\dists\gradle-<_version>-all\<_number_random_maybe>\gradle-<_version>

\Android studio\gradle didn't worked for me.

And "Default gradle wrapper" wasn't configured while importing (cloning) the project from bitbucket

If it causes problem to figure out the path, here is my path :

C:\Users\prabs\.gradle\wrapper\dists\gradle-5.4.1-all\3221gyojl5jsh0helicew7rwx\gradle-5.4.1

To suppress warnings while leaving all other error reporting enabled:

thanks to @thusharaK I could reset the root password without knowing the old password.

On ubuntu I did the following:

sudo service mysql stop
sudo mysqld_safe --skip-grant-tables --skip-syslog --skip-networking

Then run mysql in a new terminal:

mysql -u root

And run the following queries to change the password:

UPDATE mysql.user SET authentication_string=PASSWORD('password') WHERE User='root';
FLUSH PRIVILEGES;

In MySQL 5.7, the password field in mysql.user table field was removed, now the field name is 'authentication_string'.

Quit the mysql safe mode and start mysql service by:

mysqladmin shutdown
sudo service mysql start

Also note that using the "foreach" method in the original question does have some limitations, such as not being able to remove items from the list during the iteration.

The new for-loop is easier to read and removes the need for a separate iterator, but is only really usable in read-only iteration passes.

WinForms

Add an event handler for the Control.DoubleClick event for your ListBox, and in that event handler open up a MessageBox displaying the selected item.

E.g.:

 private void ListBox1_DoubleClick(object sender, EventArgs e)
 {
     if (ListBox1.SelectedItem != null)
     {
         MessageBox.Show(ListBox1.SelectedItem.ToString());
     }
 }

Where ListBox1 is the name of your ListBox.

Note that you would assign the event handler like this:

ListBox1.DoubleClick += new EventHandler(ListBox1_DoubleClick);

WPF
Pretty much the same as above, but you'd use the MouseDoubleClick event instead:

ListBox1.MouseDoubleClick += new RoutedEventHandler(ListBox1_MouseDoubleClick);

And the event handler:

 private void ListBox1_MouseDoubleClick(object sender, RoutedEventArgs e)
 {
     if (ListBox1.SelectedItem != null)
     {
         MessageBox.Show(ListBox1.SelectedItem.ToString());
     }
 }

Edit: Sisya's answer checks to see if the double-click occurred over an item, which would need to be incorporated into this code to fix the issue mentioned in the comments (MessageBox shown if ListBox is double-clicked while an item is selected, but not clicked over an item).

Hope this helps!

Can you try this?

SELECT [Title], [Firstname], [Surname], [Company_name], [Interest] 
FROM [dbo].[EXTRANET_users] 
WHERE CAST(Submission_date AS DATE) = CAST(GETDATE() AS DATE)

T-SQL doesn't really have the "implied" casting like C# does - you need to explicitly use CAST (or CONVERT).

Also, use GETDATE() or CURRENT_TIMESTAMP to get the "now" date and time.

Update: since you're working against SQL Server 2000 - none of those approaches so far work. Try this instead:

SELECT [Title], [Firstname], [Surname], [Company_name], [Interest] 
FROM [dbo].[EXTRANET_users] 
WHERE DATEADD(dd, 0, DATEDIFF(dd, 0, submission_date)) = DATEADD(dd, 0, DATEDIFF(dd, 0, GETDATE()))

Ascx-files are called User Controls and are meant for reusability and also for making complex aspx-pages less complex (lift out some part of the page). They could also be beneficial for something called donut caching, that is when you would like to cache a certain part of a page.

I have reproduced the issue in my system,

postgres=# alter user my-sys with password 'pass11';
ERROR:  syntax error at or near "-"
LINE 1: alter user my-sys with password 'pass11';
                       ^

Here is the issue,

psql is asking for input and you have given again the alter query see postgres-#That's why it's giving error at alter

postgres-# alter user "my-sys" with password 'pass11';
ERROR:  syntax error at or near "alter"
LINE 2: alter user "my-sys" with password 'pass11';
        ^

Solution is as simple as the error,

postgres=# alter user "my-sys" with password 'pass11';
ALTER ROLE

You cannot use a variable to access a property via dot notation, instead use the array notation.

var obj= {
     'name' : 'jroi'
};
var a = 'name';
alert(obj.a); //will not work
alert(obj[a]); //should work and alert jroi'

This answer applies when a string is manually entered, not when it's read from somewhere.

A traditional variable-width CSV is unreadable for storing data as a string variable. Especially for use inside a .py file, consider fixed-width pipe-separated data instead. Various IDEs and editors may have a plugin to format pipe-separated text into a neat table.

Using read_csv

Store the following in a utility module, e.g. util/pandas.py. An example is included in the function's docstring.

import io
import re

import pandas as pd


def read_psv(str_input: str, **kwargs) -> pd.DataFrame:
    """Read a Pandas object from a pipe-separated table contained within a string.

    Input example:
        | int_score | ext_score | eligible |
        |           | 701       | True     |
        | 221.3     | 0         | False    |
        |           | 576       | True     |
        | 300       | 600       | True     |

    The leading and trailing pipes are optional, but if one is present,
    so must be the other.

    `kwargs` are passed to `read_csv`. They must not include `sep`.

    In PyCharm, the "Pipe Table Formatter" plugin has a "Format" feature that can 
    be used to neatly format a table.

    Ref: https://stackoverflow.com/a/46471952/
    """

    substitutions = [
        ('^ *', ''),  # Remove leading spaces
        (' *$', ''),  # Remove trailing spaces
        (r' *\| *', '|'),  # Remove spaces between columns
    ]
    if all(line.lstrip().startswith('|') and line.rstrip().endswith('|') for line in str_input.strip().split('\n')):
        substitutions.extend([
            (r'^\|', ''),  # Remove redundant leading delimiter
            (r'\|$', ''),  # Remove redundant trailing delimiter
        ])
    for pattern, replacement in substitutions:
        str_input = re.sub(pattern, replacement, str_input, flags=re.MULTILINE)
    return pd.read_csv(io.StringIO(str_input), sep='|', **kwargs)

Non-working alternatives

The code below doesn't work properly because it adds an empty column on both the left and right sides.

df = pd.read_csv(io.StringIO(df_str), sep=r'\s*\|\s*', engine='python')

As for read_fwf, it doesn't actually use so many of the optional kwargs that read_csv accepts and uses. As such, it shouldn't be used at all for pipe-separated data.

Remove the display:none, and use ng-show instead:

<ul class="procedures">
    <li ng-repeat="procedure in procedures | filter:query | orderBy:orderProp">
        <h4><a href="#" ng-click="showDetails = ! showDetails">{{procedure.definition}}</a></h4>

            <p>Average total payments: {{procedure.payments}}</p>
         </div>
    </li>
</ul>

Here's the fiddle: http://jsfiddle.net/asmKj/

You can also use ng-class to toggle a class:

<div class="procedure-details" ng-class="{ 'hidden': ! showDetails }">

I like this more, since it allows you to do some nice transitions: http://jsfiddle.net/asmKj/1/

Truncating the table wont be possible even if you disable the foreign keys.so you can use delete command to remove all the records from the table,but be aware if you are using delete command for a table which consists of millions of records then your package will be slow and your transaction log size will increase and it may fill up your valuable disk space.

If you drop the constraints it may happen that you will fill up your table with unclean data and when you try to recreate the constraints it may not allow you to as it will give errors. so make sure that if you drop the constraints,you are loading data which are correctly related to each other and satisfy the constraint relations which you are going to recreate.

so please carefully think the pros and cons of each method and use it according to your requirements

It should be a problem in your version of grep.

Your test cases are working correctly here on my machine:

$ echo "abc" | grep -io abc
abc
$ echo "ABC" | grep -io abc
ABC

And my version is:

$ grep --version
grep (GNU grep) 2.10

The standard associative-container erase idiom:

for (auto it = m.cbegin(); it != m.cend() /* not hoisted */; /* no increment */)
{
  if (must_delete)
  {
    m.erase(it++);    // or "it = m.erase(it)" since C++11
  }
  else
  {
    ++it;
  }
}

Note that we really want an ordinary for loop here, since we are modifying the container itself. The range-based loop should be strictly reserved for situations where we only care about the elements. The syntax for the RBFL makes this clear by not even exposing the container inside the loop body.

Edit. Pre-C++11, you could not erase const-iterators. There you would have to say:

for (std::map<K,V>::iterator it = m.begin(); it != m.end(); ) { /* ... */ }

Erasing an element from a container is not at odds with constness of the element. By analogy, it has always been perfectly legitimate to delete p where p is a pointer-to-constant. Constness does not constrain lifetime; const values in C++ can still stop existing.

None of the above work on OSX.

Do the following:

perl -pi -w -e 's/SEARCH_FOR/REPLACE_WITH/g;' *.txt

You could use bash string substitution for any relative path $line:

line=$(echo ${line/#..\//`cd ..; pwd`\/})
line=$(echo ${line/#.\//`pwd`\/})
echo $line

The basic front-of-string substitution follows the formula
${string/#substring/replacement}
which is discussed well here: https://www.tldp.org/LDP/abs/html/string-manipulation.html

The \ character negates the / when we want it to be part of the string that we find/replace.

In MVC4 WebAPI 404 can be handle in the following way,

COURSES APICONTROLLER

    // GET /api/courses/5
    public HttpResponseMessage<Courses> Get(int id)
    {
        HttpResponseMessage<Courses> resp = null;

        var aCourse = _courses.Where(c => c.Id == id).FirstOrDefault();

        resp = aCourse == null ? new HttpResponseMessage<Courses>(System.Net.HttpStatusCode.NotFound) : new HttpResponseMessage<Courses>(aCourse);

        return resp;
    }

HOME CONTROLLER

public ActionResult Course(int id)
{
    return View(id);
}

VIEW

<div id="course"></div>
<script type="text/javascript">
    var id = @Model;
    var course = $('#course');
    $.ajax({    
        url: '/api/courses/' + id,
        success: function (data) {
            course.text(data.Name);
        },
        statusCode: {
            404: function() 
            {
                course.text('Course not available!');    
            }
        }
    });
</script>

GLOBAL

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{id}",
        defaults: new { id = RouteParameter.Optional }
    );

    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
    );
}

RESULTS

This will work:

/^(()?\d{3}())?(-|\s)?\d{3}(-|\s)?\d{4}$/

The ? character signifies that the preceding group should be matched zero or one times. The group (-|\s) will match either a - or a | character. Adding ? after the second occurrence of this group in your regex allows you to match a sequence of 10 consecutive digits.

Try using a wildcard like this

=VLOOKUP(LEFT(A1,3)&"*",B$2:B$22,1,FALSE)

so if A1 is "barry" that formula will return the first value in B2:B22 that starts with "bar"

Using openCV and numpy it is as easy as this:

import cv2

img = cv2.imread('path/to/img',0)
height, width = img.shape[:2]

There are several different ways you can handle this. You could add a RequiredFieldValidator as well as a RangeValidator (if that works for your case) or you could add a CustomFieldValidator.

The three things that get installed that you will need to delete are:

1. Packages/modules
2. Scripts
3. Data files

Now on my linux system these live in:

1. /usr/lib/python2.5/site-packages
2. /usr/bin
3. /usr/share

But on a windows system they are more likely to be entirely within the Python distribution directory. I have no idea about OSX except it is more likey to follow the linux pattern.

An enum is only guaranteed to be large enough to hold int values. The compiler is free to choose the actual type used based on the enumeration constants defined so it can choose a smaller type if it can represent the values you define. If you need enumeration constants that don't fit into an int you will need to use compiler-specific extensions to do so.

LD_LIBRARY_PATH is searched when the program starts, LIBRARY_PATH is searched at link time.

caveat from comments:

• When linking libraries with ld (instead of gcc or g++), the LIBRARY_PATH or LD_LIBRARY_PATH environment variables are not read.
• When linking libraries with gcc or g++, the LIBRARY_PATH environment variable is read (see documentation "gcc uses these directories when searching for ordinary libraries").

The 500 code would normally indicate an error on the server, not anything with your code. Some thoughts

• Talk to the server developer for more info. You can't get more info directly.
• Verify your arguments into the call (values). Look for anything you might think could cause a problem for the server process. The process should not die and should return you a better code, but bugs happen there also.
• Could be intermittent, like if the server database goes down. May be worth trying at another time.

If you’re not opposed to jquery, this can be done in one line:

jQuery 1.7+

$("#myEl").off()

jQuery < 1.7

$('#myEl').replaceWith($('#myEl').clone());

Here’s an example:

http://jsfiddle.net/LkfLezgd/3/

Take a look at numpy.reshape .

>>> arr = numpy.zeros((50,100,25))
>>> arr.shape
# (50, 100, 25)

>>> new_arr = arr.reshape(5000,25)
>>> new_arr.shape   
# (5000, 25)

# One shape dimension can be -1. 
# In this case, the value is inferred from 
# the length of the array and remaining dimensions.
>>> another_arr = arr.reshape(-1, arr.shape[-1])
>>> another_arr.shape
# (5000, 25)

Well, its true that we can use Vb Script for what you intended to do. We can open an application through the code like Internet Explorer. We can navigate to site you intend for. Later we can check the element names of Text Boxes which require username and password; can set then and then Login. It works fine all of using code.

No manual interaction with the website. And eventually you will end up signing in by just double clicking the file.

To get you started :

Set objIE = CreateObject("InternetExplorer.Application")

Call objIE.Navigate("https://gmail.com")

This will open an instance of internet explore and navigate to gmail. Rest you can learn and apply.

For rendering my models in JSON in django 1.9 I had to do the following in my views.py:

from django.core import serializers
from django.http import HttpResponse
from .models import Mymodel

def index(request):
    objs = Mymodel.objects.all()
    jsondata = serializers.serialize('json', objs)
    return HttpResponse(jsondata, content_type='application/json')

You can do it with 2 ways. In template and in Controller. In template you can set your filtered array to another variable, then use it like you want. Here is how to do it:

<ul>
  <li data-ng-repeat="user in usersList = (users | gender:filterGender)" data-ng-bind="user.name"></li>
</ul>
 ....
<span>{{ usersList.length | number }}</span>

If you need examples, see the AngularJs filtered count examples/demos

Actually what u did is also not wrong your declaration is right . With your declaration JVM will create a ArrayList of integer arrays i.e each entry in arraylist correspond to an integer array hence your add function should pass a integer array as a parameter.

For Ex:

list.add(new Integer[3]);

In this way first entry of ArrayList is an integer array which can hold at max 3 values.

Another Java 8 one-liner:

List<String> newList = Stream.of(listOne, listTwo)
                            .flatMap(Collection::stream)
                            .collect(Collectors.toList());

As a bonus, since Stream.of() is variadic, you may concatenate as many lists as you like.

List<String> newList = Stream.of(listOne, listTwo, listThree)
                            .flatMap(Collection::stream)
                            .collect(Collectors.toList());

I have been investigating these ideas and here is my five cents worth. It avoids calling BoundaryNorm as well as specifying norm as an argument to scatter and colorbar. However I have found no way of eliminating the rather long-winded call to matplotlib.colors.LinearSegmentedColormap.from_list.

Some background is that matplotlib provides so-called qualitative colormaps, intended to use with discrete data. Set1, e.g., has 9 easily distinguishable colors, and tab20 could be used for 20 colors. With these maps it could be natural to use their first n colors to color scatter plots with n categories, as the following example does. The example also produces a colorbar with n discrete colors approprately labelled.

import matplotlib, numpy as np, matplotlib.pyplot as plt
n = 5
from_list = matplotlib.colors.LinearSegmentedColormap.from_list
cm = from_list(None, plt.cm.Set1(range(0,n)), n)
x = np.arange(99)
y = x % 11
z = x % n
plt.scatter(x, y, c=z, cmap=cm)
plt.clim(-0.5, n-0.5)
cb = plt.colorbar(ticks=range(0,n), label='Group')
cb.ax.tick_params(length=0)

which produces the image below. The n in the call to Set1 specifies the first n colors of that colormap, and the last n in the call to from_list specifies to construct a map with n colors (the default being 256). In order to set cm as the default colormap with plt.set_cmap, I found it to be necessary to give it a name and register it, viz:

cm = from_list('Set15', plt.cm.Set1(range(0,n)), n)
plt.cm.register_cmap(None, cm)
plt.set_cmap(cm)
...
plt.scatter(x, y, c=z)

IF exists

IF exists (select * from table_1 where col1 = 'value')
BEGIN
    -- one or more
    insert into table_1 (col1) values ('valueB')
END
ELSE
    -- zero
    insert into table_1 (col1) values ('value') 

Everyone is correct. However, if you're also busy testing your code your own application might still "own" the socket if it starts and stops relatively quickly. Try SO_REUSEADDR as a socket option:

What exactly does SO_REUSEADDR do?

This socket option tells the kernel that even if this port is busy (in the TIME_WAIT state), go ahead and reuse it anyway. If it is busy, but with another state, you will still get an address already in use error. It is useful if your server has been shut down, and then restarted right away while sockets are still active on its port. You should be aware that if any unexpected data comes in, it may confuse your server, but while this is possible, it is not likely.

It has been pointed out that "A socket is a 5 tuple (proto, local addr, local port, remote addr, remote port). SO_REUSEADDR just says that you can reuse local addresses. The 5 tuple still must be unique!" by Michael Hunter ([email protected]). This is true, and this is why it is very unlikely that unexpected data will ever be seen by your server. The danger is that such a 5 tuple is still floating around on the net, and while it is bouncing around, a new connection from the same client, on the same system, happens to get the same remote port. This is explained by Richard Stevens in ``2.7 Please explain the TIME_WAIT state.''.

Are you using MySQL or PostgreSQL?

You want to use JOIN syntax, not UNION. For example, using INNER JOIN:

CREATE VIEW V AS
SELECT POP.country, POP.year, POP.pop, FOOD.food, INCOME.income
FROM POP
INNER JOIN FOOD ON (POP.country=FOOD.country) AND (POP.year=FOOD.year)
INNER JOIN INCOME ON (POP.country=INCOME.country) AND (POP.year=INCOME.year)

However, this will only show results when each country and year are present in all three tables. If this is not what you want, look into left outer joins (using the same link above).

If you want to be able to call the func with or without the parameter you can create a second func of the same name which calls the other.

func test(firstThing: Int?) {
    if firstThing != nil {
        print(firstThing!)
    }
    print("done")
}

func test() {
    test(firstThing: nil)
}

now you can call a function named test without or without the parameter.

// both work
test()
test(firstThing: 5)

request.remote_ip is an interpretation of all the available IP address information and it will make a best-guess. If you access the variables directly you assume responsibility for testing them in the correct precedence order. Proxies introduce a number of headers that create environment variables with different names.

Taking a uniform random variable as the value of RGB may generate a large amount of gray, white, and black, which are often not the colors we want.

The cv::applyColorMap can easily generate a random RGB palette, and you can choose a favorite color map from the list here

Example for C++11:

#include <algorithm>
#include <numeric>
#include <random>
#include <opencv2/opencv.hpp>

std::random_device rd;
std::default_random_engine re(rd());

// Generating randomized palette
cv::Mat palette(1, 255, CV_8U);
std::iota(palette.data, palette.data + 255, 0);
std::shuffle(palette.data, palette.data + 255, re);
cv::applyColorMap(palette, palette, cv::COLORMAP_JET);

// ...

// Picking random color from palette and drawing
auto randColor = palette.at<cv::Vec3b>(i % palette.cols);
cv::rectangle(img, cv::Rect(0, 0, 100, 100), randColor, -1);

Example for Python3:

import numpy as np, cv2

palette = np.arange(0, 255, dtype=np.uint8).reshape(1, 255, 1)
palette = cv2.applyColorMap(palette, cv2.COLORMAP_JET).squeeze(0)
np.random.shuffle(palette)
# ...

rand_color = tuple(palette[i % palette.shape[0]].tolist())
cv2.rectangle(img, (0, 0), (100, 100), rand_color, -1)

If you don't need so many colors, you can just cut the palette to the desired length.

@klode's answer is right.

However, you are supposed to set another response header to make your header accessible to others.

Example:

First, you add 'page-size' in response header

response.set('page-size', 20);

Then, all you need to do is expose your header

response.set('Access-Control-Expose-Headers', 'page-size')

It happens when you are trying to access secure Website like Https.

I hope you missed 's'

Try Changing URL to curl -sS -u "username:password" https://www.example.com/backup.php

NSLocale* currentLocale = [NSLocale currentLocale];
[[NSDate date] descriptionWithLocale:currentLocale];  

or use

NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
// or @"yyyy-MM-dd hh:mm:ss a" if you prefer the time with AM/PM 
NSLog(@"%@",[dateFormatter stringFromDate:[NSDate date]]);

You could use the Tkinter module, which is the standard Python interface to the Tk GUI toolkit and you don't need extra download. See https://docs.python.org/2/library/tkinter.html.

(For Python 3, Tkinter is renamed to tkinter)

Here is how to set RGB values:

#from http://tkinter.unpythonic.net/wiki/PhotoImage
from Tkinter import *

root = Tk()

def pixel(image, pos, color):
    """Place pixel at pos=(x,y) on image, with color=(r,g,b)."""
    r,g,b = color
    x,y = pos
    image.put("#%02x%02x%02x" % (r,g,b), (y, x))

photo = PhotoImage(width=32, height=32)

pixel(photo, (16,16), (255,0,0))  # One lone pixel in the middle...

label = Label(root, image=photo)
label.grid()
root.mainloop()

And get RGB:

#from http://www.kosbie.net/cmu/spring-14/15-112/handouts/steganographyEncoder.py
def getRGB(image, x, y):
    value = image.get(x, y)
    return tuple(map(int, value.split(" ")))

All these answers with .ReadAllBytes(). Another, similar (I won't say duplicate, since they were trying to refactor their code) question was asked on SO here: Best way to read a large file into a byte array in C#?

A comment was made on one of the posts regarding .ReadAllBytes():

File.ReadAllBytes throws OutOfMemoryException with big files (tested with 630 MB file 
and it failed) – juanjo.arana Mar 13 '13 at 1:31

A better approach, to me, would be something like this, with BinaryReader:

public static byte[] FileToByteArray(string fileName)
{
    byte[] fileData = null;

    using (FileStream fs = File.OpenRead(fileName)) 
    { 
        var binaryReader = new BinaryReader(fs); 
        fileData = binaryReader.ReadBytes((int)fs.Length); 
    }
    return fileData;
}

But that's just me...

Of course, this all assumes you have the memory to handle the byte[] once it is read in, and I didn't put in the File.Exists check to ensure the file is there before proceeding, as you'd do that before calling this code.

private void indBoxProject_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    int NewProjID = (e.AddedItems[0] as kProject).ProjectID;
    this.MyProject = new kProject(NewProjID);
    LoadWorkPhase();
}

The use of the e.AddedItems[0] as kProject where kProject is a class that holds the data worked for me as it was defaulting to the RemovedItems[0] before I have made this explicit distinction. Thanks SwDevMan81 for the initial information that answered this question for me.

In a POST request, the parameters are sent in the body of the request, that's why you don't see them in the URL.

If you want to see them, change

    type: 'POST',

to

    type: 'GET',

Note that browsers have development tools which lets you see the complete requests that your code issues. In Chrome, it's in the "Network" panel.

If you just have included a layout file at the beginning of onCreate() inside setContentView and want to get this layout to add new elements programmatically try this:

ViewGroup linearLayout = (ViewGroup) findViewById(R.id.linearLayoutID);

then you can create a new Button for example and just add it:

Button bt = new Button(this);
bt.setText("A Button");
bt.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, 
                                    LayoutParams.WRAP_CONTENT));
linerLayout.addView(bt);

Use IFERROR(value, value_if_error)

This works for me. Tested in codeigniter 3.1.11, PHP 5.6.40 I use a virtualhost in my apache2 config in testing server.

<VirtualHost *:80>
     ServerAdmin [email protected]
     DocumentRoot (__DIR__)
     ServerName mydomain
     ##ErrorLog "logs/dummy-host2.example.com-error.log"
     ##CustomLog "logs/dummy-host2.example.com-access.log" common
     <Directory "(__DIR__)">
        Require all granted
        AllowOverride All
   </Directory>
</VirtualHost>

And /.htaccess content

    <IfModule mod_rewrite.c>
       RewriteEngine On
       RewriteCond %{REQUEST_FILENAME} !-f
       RewriteCond %{REQUEST_FILENAME} !-d
       RewriteRule ^(.*)$ index.php/$1 [L] 
    </IfModule>

(question) Don't you get that info in

select * from pg_user;

or using the view pg_stat_activity:

select * from pg_stat_activity;

Added:

the view says:

One row per server process, showing database OID, database name, process ID, user OID, user name, current query, query's waiting status, time at which the current query began execution, time at which the process was started, and client's address and port number. The columns that report data on the current query are available unless the parameter stats_command_string has been turned off. Furthermore, these columns are only visible if the user examining the view is a superuser or the same as the user owning the process being reported on.

can't you filter and get that information? that will be the current users on the Database, you can use began execution time to get all queries from last 5 minutes for example...

something like that.

The following commands (modified after those found here) worked for me on my WSL install of Ubuntu after hours of trial and error:

sudo service mysql stop
sudo mysqld --skip-grant-tables &
mysql -u root mysql
UPDATE mysql.user SET authentication_string=null WHERE User='root';
flush privileges;
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your_new_password_here';
flush privileges;
exit;

Use the new viewWillTransitionToSize(_:withTransitionCoordinator:)

Here's my symfony 1.4 virtual host file on debian, which works fine.

  <Directory /var/www/sf_project/web/>
    Options All Indexes FollowSymLinks    
    AllowOverride All
    Order allow,deny
    Allow from all
  </Directory>

If you wan't to restrict access to a specific ip range, e.g. localhost use this:

Allow from 127.0.0.0/8

The mod_authz_host is responsible for filtering ip ranges. You can look up detailed things in there.

But maybe the problem could be related to some kind of misconfiguration in your "apache2.conf".

On what OS is the apache running?

You have to convert input x and y into int like below.

x=int(x)
y=int(y)

issue is with the /var/lib/jenkins/.ssh/known_hosts. It exists in the first case, but not in the second one. This means you are running either on different system or the second case is somehow jailed in chroot or by other means separated from the rest of the filesystem (this is a good idea for running random code from jenkins).

Next steps are finding out how are the chroots for this user created and modify the known hosts inside this chroot. Or just go other ways of ignoring known hosts, such as ssh-keyscan, StrictHostKeyChecking=no or so.

I doubt whether the people enthusiastically shouting "HTTP Authentication" ever tried making a browser-based application (instead of a machine-to-machine web service) with REST (no offense intended - I just don't think they ever faced the complications).

Problems I found with using HTTP Authentication on RESTful services that produce HTML pages to be viewed in a browser are:

• user typically gets an ugly browser-made login box, which is very user-unfriendly. you cannot add password retrieval, help boxes, etcetera.
• logging out or logging in under a different name is a problem - browsers will keep sending authentication information to the site until you close the window
• timeouts are difficult

A very insightful article that tackles these point by point is here, but this results in a lot of browser-specific javascript hackery, workarounds for workarounds, et cetera. As such, it is also not forward-compatible so will require constant maintenance as new browsers are released. I do not consider that clean and clear design, plus I feel it is a lot of extra work and headache just so that I can enthusiastically show my REST-badge to my friends.

I believe cookies are the solution. But wait, cookies are evil, aren't they? No, they're not, the way cookies are often used is evil. A cookie itself is just a piece of client-side information, just like the HTTP authentication info that the browser would keep track of while you browse. And this piece of client-side information is sent to the server at every request, again just like the HTTP Authentication info would be. Conceptually, the only difference is that the content of this piece of client-side state can be determined by the server as part of its response.

By making sessions a RESTful resource with just the following rules:

• A session maps a key to a user id (and possibly a last-action-timestamp for timeouts)
• If a session exists, then that means that the key is valid.
• Login means POSTing to /sessions, a new key is set as a cookie
• Logout means DELETEing /sessions/{key} (with the overloaded POST, remember, we're a browser, and HTML 5 is a long way to go yet)
• Authentication is done by sending the key as a cookie at every request and checking whether the session exists and is valid

The only difference to HTTP Authentication, now, is that the authentication key is generated by the server and sent to the client who keeps sending it back, instead of the client computing it from the entered credentials.

converter42 adds that when using https (which we should), it is important that the cookie will have its secure flag set so that authentication info is never sent over a non-secure connection. Great point, hadn't seen it myself.

I feel that this is a sufficient solution that works fine, but I must admit that I'm not enough of a security expert to identify potential holes in this scheme - all I know is that hundreds of non-RESTful web applications use essentially the same login protocol ($_SESSION in PHP, HttpSession in Java EE, etc.). The cookie header contents are simply used to address a server-side resource, just like an accept-language might be used to access translation resources, etcetera. I feel that it is the same, but maybe others don't? What do you think, guys?

What about the shortcut CTRL+L?

It works for all shells e.g. Python, Bash, MySQL, MATLAB, etc.

When there is one commit only in the branch, I usually do

git merge branch_name --ff

Here is simplified and more expressive solution. It works for both value and reference types. The approach of lifting is taken from @HepaKKes answer.

Association code:

import ObjectiveC

final class Lifted<T> {
    let value: T
    init(_ x: T) {
        value = x
    }
}

private func lift<T>(_ x: T) -> Lifted<T>  {
    return Lifted(x)
}

func associated<T>(to base: AnyObject,
                key: UnsafePointer<UInt8>,
                policy: objc_AssociationPolicy = .OBJC_ASSOCIATION_RETAIN,
                initialiser: () -> T) -> T {
    if let v = objc_getAssociatedObject(base, key) as? T {
        return v
    }

    if let v = objc_getAssociatedObject(base, key) as? Lifted<T> {
        return v.value
    }

    let lifted = Lifted(initialiser())
    objc_setAssociatedObject(base, key, lifted, policy)
    return lifted.value
}

func associate<T>(to base: AnyObject, key: UnsafePointer<UInt8>, value: T, policy: objc_AssociationPolicy = .OBJC_ASSOCIATION_RETAIN) {
    if let v: AnyObject = value as AnyObject? {
        objc_setAssociatedObject(base, key, v, policy)
    }
    else {
        objc_setAssociatedObject(base, key, lift(value), policy)
    }
}

Example of usage:

1) Create extension and associate properties to it. Let's use both value and reference type properties.

extension UIButton {

    struct Keys {
        static fileprivate var color: UInt8 = 0
        static fileprivate var index: UInt8 = 0
    }

    var color: UIColor {
        get {
            return associated(to: self, key: &Keys.color) { .green }
        }
        set {
            associate(to: self, key: &Keys.color, value: newValue)
        }
    }

    var index: Int {
        get {
            return associated(to: self, key: &Keys.index) { -1 }
        }
        set {
            associate(to: self, key: &Keys.index, value: newValue)
        }
    }

}

2) Now you can use just as regular properties:

    let button = UIButton()
    print(button.color) // UIExtendedSRGBColorSpace 0 1 0 1 == green
    button.color = .black
    print(button.color) // UIExtendedGrayColorSpace 0 1 == black

    print(button.index) // -1
    button.index = 3
    print(button.index) // 3

More details:

1. Lifting is needed for wrapping value types.
2. Default associated object behavior is retain. If you want to learn more about associated objects, I'd recommend checking this article.
