dir /s /b /a:d>output.txt will port it to a text file

type NUL > EmptyFile.txt

After reading the previous two posts, this blend of the two is what I came up with. It seems a little cleaner. There is no need to worry about redirecting the "1 file(s) copied." message to NUL, like the previous post does, and it looks nice next to the ECHO OutputLineFromLoop >> Emptyfile.txt that will usually follow in a batch file.

Make sure there are no 'echo off' statements in the scripts and call 'echo on' after calling each script to reset any you have missed.

The reason is that if echo is left on, then the command interpreter will output each command (after parameter processing) before executing it. Makes it look really bad for using in production, but very useful for debugging purposes as you can see where output has gone wrong.

Also, make sure you are checking the ErrorLevels set by the called batch scripts and programs. Remember that there are 2 different methods used in .bat files for this. If you called a program, the Error level is in %ERRORLEVEL%, while from batch files the error level is returned in the ErrorLevel variable and doesn't need %'s around it.

set TEXT_T="myfile.txt"
set /a c=1

FOR /F "tokens=1 usebackq" %%i in (%TEXT_T%) do (
    set /a c+=1
    set OUTPUT_FILE_NAME=output_%c%.txt
    echo Output file is %OUTPUT_FILE_NAME%
    echo %%i, %c%
)

Try dir /b, for bare format.

dir /? will show you documentation of what you can do with the dir command. Here is the output from my Windows 7 machine:

C:\>dir /?
Displays a list of files and subdirectories in a directory.

DIR [drive:][path][filename] [/A[[:]attributes]] [/B] [/C] [/D] [/L] [/N]
  [/O[[:]sortorder]] [/P] [/Q] [/R] [/S] [/T[[:]timefield]] [/W] [/X] [/4]

  [drive:][path][filename]
              Specifies drive, directory, and/or files to list.

  /A          Displays files with specified attributes.
  attributes   D  Directories                R  Read-only files
               H  Hidden files               A  Files ready for archiving
               S  System files               I  Not content indexed files
               L  Reparse Points             -  Prefix meaning not
  /B          Uses bare format (no heading information or summary).
  /C          Display the thousand separator in file sizes.  This is the
              default.  Use /-C to disable display of separator.
  /D          Same as wide but files are list sorted by column.
  /L          Uses lowercase.
  /N          New long list format where filenames are on the far right.
  /O          List by files in sorted order.
  sortorder    N  By name (alphabetic)       S  By size (smallest first)
               E  By extension (alphabetic)  D  By date/time (oldest first)
               G  Group directories first    -  Prefix to reverse order
  /P          Pauses after each screenful of information.
  /Q          Display the owner of the file.
  /R          Display alternate data streams of the file.
  /S          Displays files in specified directory and all subdirectories.
  /T          Controls which time field displayed or used for sorting
  timefield   C  Creation
              A  Last Access
              W  Last Written
  /W          Uses wide list format.
  /X          This displays the short names generated for non-8dot3 file
              names.  The format is that of /N with the short name inserted
              before the long name. If no short name is present, blanks are
              displayed in its place.
  /4          Displays four-digit years

Switches may be preset in the DIRCMD environment variable.  Override
preset switches by prefixing any switch with - (hyphen)--for example, /-W.

In command prompt go to the main directory you want the list for ... and type the command tree /f

Use xcopy /s I:\*.* N:\

This is should do.

If you want to add REM at the beginning of each line instead of using GOTO, you can use Notepad++ to do this easily following these steps:

1. Select the block of lines
2. hit Ctrl-Q

Repeat steps to uncomment

copy *.csv new.csv

No need for /b as csv isn't a binary file type.

A little bit late for the party, but it's an interessting question.

You can write your own inc.bat for incrementing a number.
It can increment numbers from 0 to 9998.

@echo off
if "%1"==":inc" goto :increment

call %0 :inc %counter0%
set counter0=%_cnt%
if %_overflow%==0 goto :exit 

call %0 :inc %counter1%
set counter1=%_cnt%
if %_overflow%==0 goto :exit 

call %0 :inc %counter2%
set counter2=%_cnt%
if %_overflow%==0 goto :exit 

call %0 :inc %counter3%
set counter3=%_cnt%
goto :exit

:increment
set _overflow=0
set _cnt=%2

if "%_cnt%"=="" set _cnt=0

if %_cnt%==9 goto :overflow
if %_cnt%==8 set _cnt=9
if %_cnt%==7 set _cnt=8
if %_cnt%==6 set _cnt=7
if %_cnt%==5 set _cnt=6
if %_cnt%==4 set _cnt=5
if %_cnt%==3 set _cnt=4
if %_cnt%==2 set _cnt=3
if %_cnt%==1 set _cnt=2
if %_cnt%==0 set _cnt=1
goto :exit

:overflow
set _cnt=0
set _overflow=1
goto :exit

:exit
set count=%counter3%%counter2%%counter1%%counter0%

A sample for using it is here

@echo off
set counter0=0
set counter1=
set counter2=
set counter3=

:loop
call inc.bat
echo %count%
if not %count%==250 goto :loop

You can do it with the pause command, example:

dir
pause
echo Now about to end...
pause

C:\test>find /c "string" file | find ": 0" 1>nul && echo "execute command here"

It seems that the queries are not exactly the same. At least for MySQL.

Compare:

1. describe select distinct productname from northwind.products
2. describe select productname from northwind.products group by productname

The second query gives additionally "Using filesort" in Extra.

This is my function. Works with all currencies..

function toFloat(num) {
    dotPos = num.indexOf('.');
    commaPos = num.indexOf(',');

    if (dotPos < 0)
        dotPos = 0;

    if (commaPos < 0)
        commaPos = 0;

    if ((dotPos > commaPos) && dotPos)
        sep = dotPos;
    else {
        if ((commaPos > dotPos) && commaPos)
            sep = commaPos;
        else
            sep = false;
    }

    if (sep == false)
        return parseFloat(num.replace(/[^\d]/g, ""));

    return parseFloat(
        num.substr(0, sep).replace(/[^\d]/g, "") + '.' + 
        num.substr(sep+1, num.length).replace(/[^0-9]/, "")
    );

}

Usage : toFloat("$1,100.00") or toFloat("1,100.00$")

Use String.valueOf(integer).

It returns a string representation of integer.

You have a lot of type-mismatches in your code such as trying to put an int value where BigDecimal is required. The corrected version of your code:

public class Payment
{
    BigDecimal itemCost  = BigDecimal.ZERO;
    BigDecimal totalCost = BigDecimal.ZERO;

    public BigDecimal calculateCost(int itemQuantity, BigDecimal itemPrice)
    {
        itemCost  = itemPrice.multiply(new BigDecimal(itemQuantity));
        totalCost = totalCost.add(itemCost);
        return totalCost;
    }
}

Java has a method for this, "convertStringArrayToIntArray".

String numbers = sc.nextLine();
int[] intArray = convertStringArrayToIntArray(numbers.split(", "));

The ViewPager doesn't remove your fragments with the code above because it loads several views (or fragments in your case) into memory. In addition to the visible view, it also loads the view to either side of the visible one. This provides the smooth scrolling from view to view that makes the ViewPager so cool.

To achieve the effect you want, you need to do a couple of things.

1. Change the FragmentPagerAdapter to a FragmentStatePagerAdapter. The reason for this is that the FragmentPagerAdapter will keep all the views that it loads into memory forever. Where the FragmentStatePagerAdapter disposes of views that fall outside the current and traversable views.

2. Override the adapter method getItemPosition (shown below). When we call mAdapter.notifyDataSetChanged(); the ViewPager interrogates the adapter to determine what has changed in terms of positioning. We use this method to say that everything has changed so reprocess all your view positioning.

And here's the code...

private class MyPagerAdapter extends FragmentStatePagerAdapter {

    //... your existing code

    @Override
    public int getItemPosition(Object object){
        return PagerAdapter.POSITION_NONE;
    }

}

@echo off & setlocal EnableDelayedExpansion
set Var=finding the length of strings
for /l %%A in (0,1,10000) do if not "%Var%"=="!Var:~0,%%A!" (set /a Length+=1) else (echo !Length! & pause & exit /b)

set the var to whatever you want to find the length of it or change it to set /p var= so that the user inputs it. Putting this here for future reference.

Stumbled upon this thread a couple years later. In 2016, most Android devices will have API level >= 18 and should thus rely on Location.isFromMockProvider() as pointed out by Fernando.

I extensively experimented with fake/mock locations on different Android devices and distros. Unfortunately .isFromMockProvider() is not 100% reliable. Every once in a while, a fake location will not be labeled as mock. This seems to be due to some erroneous internal fusion logic in the Google Location API.

I wrote a detailed blog post about this, if you want to learn more. To summarize, if you subscribe to location updates from the Location API, then switch on a fake GPS app and print the result of each Location.toString() to the console, you will see something like this:

Notice how, in the stream of location updates, one location has the same coordinates as the others, but is not flagged as a mock and has a much poorer location accuracy.

To remedy this problem, I wrote a utility class that will reliably suppress Mock locations across all modern Android versions (API level 15 and up):

LocationAssistant - Hassle-free location updates on Android

Basically, it "distrusts" non-mock locations that are within 1km of the last known mock location and also labels them as a mock. It does this until a significant number of non-mock locations have arrived. The LocationAssistant can not only reject mock locations, but also unburdens you from most of the hassle of setting up and subscribing to location updates.

To receive only real location updates (i.e. suppress mocks), use it as follows:

public class MyActivity extends Activity implements LocationAssistant.Listener {

    private LocationAssistant assistant;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ...
        // You can specify a different accuracy and interval here.
        // The last parameter (allowMockLocations) must be 'false' to suppress mock locations.  
        assistant = new LocationAssistant(this, this, LocationAssistant.Accuracy.HIGH, 5000, false);
    }

    @Override
    protected void onResume() {
        super.onResume();
        assistant.start();
    }

    @Override
    protected void onPause() {
        assistant.stop();
        super.onPause();
    }

    @Override
    public void onNewLocationAvailable(Location location) {
        // No mock locations arriving here
    }

    ...
}

onNewLocationAvailable() will now only be invoked with real location info. There are some more listener methods you need to implement, but in the context of your question (how to prevent GPS spoofing) this is basically it.

Of course, with a rooted OS you can still find ways of spoofing location info that are impossible for normal apps to detect.

The easiest way to overwrite a text file is to use a public static field.

this will overwrite the file every time because your only using false the first time through.`

public static boolean appendFile;

Use it to allow only one time through the write sequence for the append field of the write code to be false.

// use your field before processing the write code

appendFile = False;

File fnew=new File("../playlist/"+existingPlaylist.getText()+".txt");
String source = textArea.getText();
System.out.println(source);
FileWriter f2;

try {
     //change this line to read this

    // f2 = new FileWriter(fnew,false);

    // to read this
    f2 = new FileWriter(fnew,appendFile); // important part
    f2.write(source);

    // change field back to true so the rest of the new data will
    // append to the new file.

    appendFile = true;

    f2.close();
 } catch (IOException e) {
       // TODO Auto-generated catch block
       e.printStackTrace();
 }           

A solution that do not require a lot of CSS, nor tweaking bootstrap default 12col layout:

http://jsfiddle.net/0ufdyeur/1/

HTML:

<div class="stretch">

  <div class="col-lg-2"></div>
  <div class="col-lg-2"></div>
  <div class="col-lg-2"></div>
  <div class="col-lg-2"></div>
</div>

CSS:

@media (min-width: 1200px) { /*if not lg, change this criteria*/
  .stretch{
    width: 120%; /*the actual trick*/
  }
}

GUID is Microsoft's implementation of the UUID standard.

Per Wikipedia:

The term GUID usually refers to Microsoft's implementation of the Universally Unique Identifier (UUID) standard.

An updated quote from that same Wikipedia article:

RFC 4122 itself states that UUIDs "are also known as GUIDs". All this suggests that "GUID", while originally referring to a variant of UUID used by Microsoft, has become simply an alternative name for UUID…

There is a statement you can issue at the module level:

Option Compare Text

This makes all "text comparisons" case insensitive. This means the following code will show the message "this is true":

Option Compare Text

Sub testCase()
  If "UPPERcase" = "upperCASE" Then
    MsgBox "this is true: option Compare Text has been set!"
  End If
End Sub

See for example http://www.ozgrid.com/VBA/vba-case-sensitive.htm . I'm not sure it will completely solve the problem for all instances (such as the Application.Match function) but it will take care of all the if a=b statements. As for Application.Match - you may want to convert the arguments to either upper case or lower case using the LCase function.

I would like to suggest a much cleaner way. This will be useful when we have multiple storyboards

1.Create a structure with all your storyboards

struct Storyboard {
      static let main = "Main"
      static let login = "login"
      static let profile = "profile" 
      static let home = "home"
    }

2. Create a UIStoryboard extension like this

extension UIStoryboard {
  @nonobjc class var main: UIStoryboard {
    return UIStoryboard(name: Storyboard.main, bundle: nil)
  }
  @nonobjc class var journey: UIStoryboard {
    return UIStoryboard(name: Storyboard.login, bundle: nil)
  }
  @nonobjc class var quiz: UIStoryboard {
    return UIStoryboard(name: Storyboard.profile, bundle: nil)
  }
  @nonobjc class var home: UIStoryboard {
    return UIStoryboard(name: Storyboard.home, bundle: nil)
  }
}

Give the storyboard identifier as the class name, and use the below code to instantiate

let loginVc = UIStoryboard.login.instantiateViewController(withIdentifier: "\(LoginViewController.self)") as! LoginViewController

No Class Definition Exception occurs when the intended class is not found in the Class Path. At Compile Time Class : Class was generated from Java Compiler, But Somehow at Run Time the Dependent Class is not found.

Lets go through one Simple Example :

public class ClassA{
public static void main(String args[]){
     //Some gibberish Code...
     String text = ClassB.getString();
     System.out.println("Text is :" + text);
}

}

public class ClassB{
    public static String getString(){
      return "Testing Some Exception";
 }
}

Now Lets assume that the above two Java Source Code are placed in some Folder let say "NoClassDefinationFoundExceptionDemo"

Now open a shell(Assuming Java is already being setup correctly)

1. Go to Folder "NoClassDefinationFoundExceptionDemo"
2. Compile Java Source Files javac ClassB javac ClassA
3. Both Files are Compiled Sucessfully and generated Class files in the same Folder as ClassA.class and ClassB.class
4. Now Since we are overiding ClassPath to current working directory therefore we execute the following command java -cp . ClassA and It worked Successfully and you will see the Output in the screen
5. Now Lets say, You removed ClassB.class file from Present Directory. and now you execute the command again. java -cp . ClassA Now it will greet you with NoClassDefFoundException. as ClassB which is a dependency for ClassA is not found in the classpath(i.e present working directory).

You can also use INT_MAX:

http://www.cplusplus.com/reference/climits/

it's equivalent to using numeric_limits.

spoulson has it nearly right, but you need to create a List<string> from string[] first. Actually a List<int> would be better if uid is also int. List<T> supports Contains(). Doing uid.ToString().Contains(string[]) would imply that the uid as a string contains all of the values of the array as a substring??? Even if you did write the extension method the sense of it would be wrong.

[EDIT]

Unless you changed it around and wrote it for string[] as Mitch Wheat demonstrates, then you'd just be able to skip the conversion step.

[ENDEDIT]

Here is what you want, if you don't do the extension method (unless you already have the collection of potential uids as ints -- then just use List<int>() instead). This uses the chained method syntax, which I think is cleaner, and does the conversion to int to ensure that the query can be used with more providers.

var uids = arrayofuids.Select(id => int.Parse(id)).ToList();

var selected = table.Where(t => uids.Contains(t.uid));

$("#h273yrjdfhgsfyiruwyiywer").children('[value="' + i + '"]').prop("selected", true);

There is another alternative: using setAttribute rather than adding an event listener. Like this:

<!DOCTYPE html>_x000D_
<html>_x000D_
<head>_x000D_
    <meta charset="utf-8">_x000D_
    <title>Demo innerHTML and event listeners</title>_x000D_
<style>_x000D_
    div {_x000D_
        border: 1px solid black;_x000D_
        padding: 10px;_x000D_
    }_x000D_
</style>_x000D_
</head>_x000D_
<body>_x000D_
    <div>_x000D_
        <span>Click here.</span>_x000D_
    </div>_x000D_
    <script>_x000D_
        document.querySelector('span').setAttribute("onclick","alert('Hi.')");_x000D_
        document.querySelector('div').innerHTML += ' Added text.';_x000D_
    </script>_x000D_
</body>_x000D_
</html>

• If you use STS. You must have Lombok installed in your Eclipse by running lombok-xyz.jar

• Please Try the Following the Steps:

  1. Include pom in Maven .
  2. Exit/Shutdown STS
  3. Find lombok Jar in ~/.m2/repository/org/projectlombok/lombok/version.x

  4. From Command Prompt/Shell java -jar lombok-1.x.y.jar

  5. Start STS

Thats all.

EDIT: I did this and was still showing errors, as mentioned in the comments. So I updated the project: right-click on project -> Maven -> Update Project and the errors disappeared.

Also, if you had multiple event handlers attached to the same selector executing the same function, you could use

$('table.planning_grid').on('mouseenter mouseleave', function() {
    //JS Code
});

Prefix the call with Module2 (ex. Module2.IDLE). I'm assuming since you asked this that you have IDLE defined multiple times in the project, otherwise this shouldn't be necessary.

 var xxxx : { [key:number]: MyType };

You don't need a derived table at all for this.

Just put the INTO after the first SELECT

SELECT top(100)*

UNION All
SELECT top(100)*

UNION All
SELECT top(100)* 
FROM CustomerAsia
UNION All
SELECT top(100)*

In addition to the line.separator property, if you are using java 1.5 or later and the String.format (or other formatting methods) you can use %n as in

Calendar c = ...;
String s = String.format("Duke's Birthday: %1$tm %1$te,%1$tY%n", c); 
//Note `%n` at end of line                                  ^^

String s2 = String.format("Use %%n as a platform independent newline.%n"); 
//         %% becomes %        ^^
//                                        and `%n` becomes newline   ^^

See the Java 1.8 API for Formatter for more details.

Since you have an object, not a jQuery wrapper, you need to use a different variant of $.each()

$.each(json, function (key, data) {
    console.log(key)
    $.each(data, function (index, data) {
        console.log('index', data)
    })
})

Demo: Fiddle

This is because of using integer indices (ix selects those by label over -3 rather than position, and this is by design: see integer indexing in pandas "gotchas"*).

*In newer versions of pandas prefer loc or iloc to remove the ambiguity of ix as position or label:

df.iloc[-3:]

see the docs.

As Wes points out, in this specific case you should just use tail!

I know, that question has been asked a long long time ago...

I was looking for a short and elegant solution, but couldn't find satisfaction for two reasons:

First, most of the existing solutions replace a list of characters by a list of other characters. Unfortunately, it require to use a specific encoding for the php script file itself which might be unwanted.

Second, using iconv seems to be a good way, but it's not enough as the result of a converted character could be one or two characters, or a Fatal Exception.

So I wrote that small function which does the job :

function replaceAccent($string, $replacement = '_')
{
    $alnumPattern = '/^[a-zA-Z0-9 ]+$/';

    if (preg_match($alnumPattern, $string)) {
        return $string;
    }

    $ret = array_map(
        function ($chr) use ($alnumPattern, $replacement) {
            if (preg_match($alnumPattern, $chr)) {
                return $chr;
            } else {
                $chr = @iconv('ISO-8859-1', 'ASCII//TRANSLIT', $chr);
                if (strlen($chr) == 1) {
                    return $chr;
                } elseif (strlen($chr) > 1) {
                    $ret = '';
                    foreach (str_split($chr) as $char2) {
                        if (preg_match($alnumPattern, $char2)) {
                            $ret .= $char2;
                        }
                    }
                    return $ret;
                } else {
                    // replace whatever iconv fail to convert by something else
                    return $replacement;
                }
            }
        },
        str_split($string)
    );

    return implode($ret);
}

Here is what a model should look like: Make sure yours is like this.

    <?php
    class Logon_model extends CI_Model {

    function __construct()
    {
         parent::__construct();
    }

    function myFunc()
    {
      // do something
    }
}

note the upper-case class name.

To load it use:

$this->load->model('logon_model');

note all lower case.

To retrieve the information when the DomainController exists in a Domain in which your machine doesn't belong, you need something more.

  DirectoryContext domainContext =  new DirectoryContext(DirectoryContextType.Domain, "targetDomainName", "validUserInDomain", "validUserPassword");

  var domain = System.DirectoryServices.ActiveDirectory.Domain.GetDomain(domainContext);
  var controller = domain.FindDomainController();

catch function in your api should either return some data which could be handled by Api call in React class or throw new error which should be caught using a catch function in your React class code. Latter approach should be something like:

return fetch(url)
.then(function(response){
  return response.json();
})
.then(function(json){
  return {
    city: json.name,
    temperature: kelvinToF(json.main.temp),
    description: _.capitalize(json.weather[0].description)
  }
})
.catch(function(error) {
console.log('There has been a problem with your fetch operation: ' + error.message);
 // ADD THIS THROW error
  throw error;
});

Then in your React Class:

Api(region.latitude, region.longitude)
  .then((data) => {
    console.log(data);
    this.setState(data);
  }).catch((error)=>{
     console.log("Api call error");
     alert(error.message);
  });

isset() is used to check if the variable is set with the value or not and Empty() is used to check if a given variable is empty or not.

isset() returns true when the variable is not null whereas Empty() returns true if the variable is an empty string.

I think the easiest way is creating a new XML file. In this case, let's call it "example.xml" in the drawable folder, and put in the follow code:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/blue"
          android:state_pressed="true" />

</selector>

But before that you have to set the colors in the colors.xml file, in the values folder, like this:

<resources>
    <color name="blue">#0000FF</color>
</resources>

That made, you just set the Button / ImageButton to use the new layout, like this:

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/example"
/>

Then when you click that image, it will change to the color set in

<item android:drawable="@color/blue"
      android:state_pressed="true" />

giving the feedback that you want...

you can also use vertice :

private static final int verticesColors[] = {
    Color.LTGRAY, Color.LTGRAY, Color.LTGRAY, 0xFF000000, 0xFF000000, 0xFF000000
};
float verts[] = {
    point1.x, point1.y, point2.x, point2.y, point3.x, point3.y
};
canvas.drawVertices(Canvas.VertexMode.TRIANGLES, verts.length, verts, 0, null, 0, verticesColors,   0, null, 0, 0, new Paint());

i don't konw why all of the answers here make a very simple work very hard!

when there is a request on HTTP, actually a client will send a HTTP_MESSAGE to server (read about what is a HTTP_MESSAGE) and you can make a server in just 2 simple step:

1. install netcat:

in many unix-based systems you have this already installed and if you have windows just google it , the installation process is really simple, you just need a nc.exe file and then you should copy the path of this nc.exe file to your path environmet variable and check if every think is ok with nc -h

2. make a server which is listening on localhost:12345:

just type nc -l -p 12345 on your terminal and everything is done! (in mac nc -l 12345 tnx Silvio Biasiol)

now you have a server which is listening on http://localhost:12345 make a post request with axios.post('http://localhost:12345', { firstName: 'Fred' }) if you are a js develper or make your own xhr or make a form in a html file and submit it to server, sth like <form action="http://localhost:12345" method="post"> or make a request with curl or wget or etc. and then check your terminal, a raw HTTP_MESSAGE should be appear on your terminal and you can start your happy hacking ;)

$ a=(1 2 3 4)
$ echo ${#a[@]}

Here is an example using css3:

CSS:

html, body {
    height: 100%;
    margin: 0;
}
#wrap {
    padding: 10px;
    min-height: -webkit-calc(100% - 100px);     /* Chrome */
    min-height: -moz-calc(100% - 100px);     /* Firefox */
    min-height: calc(100% - 100px);     /* native */
}
.footer {
    position: relative;
    clear:both;
}

HTML:

<div id="wrap">
    body content....
</div>
<footer class="footer">
    footer content....
</footer>

jsfiddle

Update
As @Martin pointed, the ´position: relative´ is not mandatory on the .footer element, the same for clear:both. These properties are only there as an example. So, the minimum css necessary to stick the footer on the bottom should be:

html, body {
    height: 100%;
    margin: 0;
}
#wrap {
    min-height: -webkit-calc(100% - 100px);     /* Chrome */
    min-height: -moz-calc(100% - 100px);     /* Firefox */
    min-height: calc(100% - 100px);     /* native */
}

Also, there is an excellent article at css-tricks showing different ways to do this: https://css-tricks.com/couple-takes-sticky-footer/

You can use rename_axis, for removing set to None:

d = {'Index Title': ['Apples', 'Oranges', 'Puppies', 'Ducks'],'Column 1': [1.0, 2.0, 3.0, 4.0]}
df = pd.DataFrame(d).set_index('Index Title')
print (df)
             Column 1
Index Title          
Apples            1.0
Oranges           2.0
Puppies           3.0
Ducks             4.0

print (df.index.name)
Index Title

print (df.columns.name)
None

The new functionality works well in method chains.

df = df.rename_axis('foo')
print (df)
         Column 1
foo              
Apples        1.0
Oranges       2.0
Puppies       3.0
Ducks         4.0

You can also rename column names with parameter axis:

d = {'Index Title': ['Apples', 'Oranges', 'Puppies', 'Ducks'],'Column 1': [1.0, 2.0, 3.0, 4.0]}
df = pd.DataFrame(d).set_index('Index Title').rename_axis('Col Name', axis=1)
print (df)
Col Name     Column 1
Index Title          
Apples            1.0
Oranges           2.0
Puppies           3.0
Ducks             4.0

print (df.index.name)
Index Title

print (df.columns.name)
Col Name

print df.rename_axis('foo').rename_axis("bar", axis="columns")
bar      Column 1
foo              
Apples        1.0
Oranges       2.0
Puppies       3.0
Ducks         4.0

print df.rename_axis('foo').rename_axis("bar", axis=1)
bar      Column 1
foo              
Apples        1.0
Oranges       2.0
Puppies       3.0
Ducks         4.0

From version pandas 0.24.0+ is possible use parameter index and columns:

df = df.rename_axis(index='foo', columns="bar")
print (df)
bar      Column 1
foo              
Apples        1.0
Oranges       2.0
Puppies       3.0
Ducks         4.0

Removing index and columns names means set it to None:

df = df.rename_axis(index=None, columns=None)
print (df)
         Column 1
Apples        1.0
Oranges       2.0
Puppies       3.0
Ducks         4.0

If MultiIndex in index only:

mux = pd.MultiIndex.from_arrays([['Apples', 'Oranges', 'Puppies', 'Ducks'],
                                  list('abcd')], 
                                  names=['index name 1','index name 1'])


df = pd.DataFrame(np.random.randint(10, size=(4,6)), 
                  index=mux, 
                  columns=list('ABCDEF')).rename_axis('col name', axis=1)
print (df)
col name                   A  B  C  D  E  F
index name 1 index name 1                  
Apples       a             5  4  0  5  2  2
Oranges      b             5  8  2  5  9  9
Puppies      c             7  6  0  7  8  3
Ducks        d             6  5  0  1  6  0

print (df.index.name)
None

print (df.columns.name)
col name

print (df.index.names)
['index name 1', 'index name 1']

print (df.columns.names)
['col name']

df1 = df.rename_axis(('foo','bar'))
print (df1)
col name     A  B  C  D  E  F
foo     bar                  
Apples  a    5  4  0  5  2  2
Oranges b    5  8  2  5  9  9
Puppies c    7  6  0  7  8  3
Ducks   d    6  5  0  1  6  0

df2 = df.rename_axis('baz', axis=1)
print (df2)
baz                        A  B  C  D  E  F
index name 1 index name 1

Ducks        d             6  5  0  1  6  0

df2 = df.rename_axis(index=('foo','bar'), columns='baz')
print (df2)

Puppies c    7  6  0  7  8  3
Ducks   d    6  5  0  1  6  0

Removing index and columns names means set it to None:

df2 = df.rename_axis(index=(None,None), columns=None)
print (df2)

           A  B  C  D  E  F
Apples  a  6  9  9  5  4  6

Puppies c  6  3  6  3  5  1
Ducks   d  4  9  1  3  0  5

For MultiIndex in index and columns is necessary working with .names instead .name and set by list or tuples:

mux1 = pd.MultiIndex.from_arrays([['Apples', 'Oranges', 'Puppies', 'Ducks'],
                                  list('abcd')], 
                                  names=['index name 1','index name 1'])


mux2 = pd.MultiIndex.from_product([list('ABC'),
                                  list('XY')], 
                                  names=['col name 1','col name 2'])

df = pd.DataFrame(np.random.randint(10, size=(4,6)), index=mux1, columns=mux2)
print (df)
col name 1                 A     B     C   
col name 2                 X  Y  X  Y  X  Y
index name 1 index name 1                  
Apples       a             2  9  4  7  0  3
Oranges      b             9  0  6  0  9  4
Puppies      c             2  4  6  1  4  4
Ducks        d             6  6  7  1  2  8

Plural is necessary for check/set values:

print (df.index.name)
None

print (df.columns.name)
None

print (df.index.names)
['index name 1', 'index name 1']

print (df.columns.names)
['col name 1', 'col name 2']

df1 = df.rename_axis(('foo','bar'))
print (df1)
col name 1   A     B     C   
col name 2   X  Y  X  Y  X  Y
foo     bar                  
Apples  a    2  9  4  7  0  3
Oranges b    9  0  6  0  9  4
Puppies c    2  4  6  1  4  4
Ducks   d    6  6  7  1  2  8

df2 = df.rename_axis(('baz','bak'), axis=1)
print (df2)
baz                        A     B     C   
bak                        X  Y  X  Y  X  Y
index name 1 index name 1                  
Apples       a             2  9  4  7  0  3
Oranges      b             9  0  6  0  9  4
Puppies      c             2  4  6  1  4  4
Ducks        d             6  6  7  1  2  8

df2 = df.rename_axis(index=('foo','bar'), columns=('baz','bak'))
print (df2)
baz          A     B     C   
bak          X  Y  X  Y  X  Y
foo     bar                  
Apples  a    2  9  4  7  0  3
Oranges b    9  0  6  0  9  4
Puppies c    2  4  6  1  4  4
Ducks   d    6  6  7  1  2  8

Removing index and columns names means set it to None:

df2 = df.rename_axis(index=(None,None), columns=(None,None))
print (df2)

           A     B     C   
           X  Y  X  Y  X  Y
Apples  a  2  0  2  5  2  0
Oranges b  1  7  5  5  4  8
Puppies c  2  4  6  3  6  5
Ducks   d  9  6  3  9  7  0

And @Jeff solution:

df.index.names = ['foo','bar']
df.columns.names = ['baz','bak']
print (df)

baz          A     B     C   
bak          X  Y  X  Y  X  Y
foo     bar                  
Apples  a    3  4  7  3  3  3
Oranges b    1  2  5  8  1  0
Puppies c    9  6  3  9  6  3
Ducks   d    3  2  1  0  1  0

I faced similar problem on windows server 2012 STD 64 bit , my problem is resolved after updating windows with all available windows updates.

Provide the source image (img) size as the first rectangle:

ctx.drawImage(img, 0, 0, img.width,    img.height,     // source rectangle
                   0, 0, canvas.width, canvas.height); // destination rectangle

The second rectangle will be the destination size (what source rectangle will be scaled to).

In Access 2013. Drop a "Text Box" control onto your form. On the Property Sheet for the control under the Format tab find the Format property. Set this to one of the date format options. Job's done.

If d is a dictionary, then d.get(k, v) means, give me the value of k in d, unless k isn't there, in which case give me v. It's being used here to get the current count of the character, which should start at 0 if the character hasn't been encountered before.

The stringr package provides the str_sub function, which is a bit easier to use than substr, especially if you want to extract right portions of your string :

R> str_sub("leftright",1,4)
[1] "left"
R> str_sub("leftright",-5,-1)
[1] "right"

Answer

You can't according to the PHP manual:

Once the cookies have been set, they can be accessed on the next page load with the $_COOKIE or $HTTP_COOKIE_VARS arrays.

This is because cookies are sent in response headers to the browser and the browser must then send them back with the next request. This is why they are only available on the second page load.

Work around

But you can work around it by also setting $_COOKIE when you call setcookie():

if(!isset($_COOKIE['lg'])) {
    setcookie('lg', 'ro');
    $_COOKIE['lg'] = 'ro';
}
echo $_COOKIE['lg'];

Responding to the Forum Thread for the sake of completeness. Amazon has stopped using the the ECU - Elastic Compute Units and moved on to a vCPU based measure. So ignoring the ECU you pretty much can start comparing the EC2 Instances' sizes as CPU (Clock Speed), number of CPUs, RAM, storage etc.

Every instance families' instance configurations are published as number of vCPU and what is the physical processor. Detailed info and screenshot obstained from here http://aws.amazon.com/ec2/instance-types/#instance-type-matrix

The difference in assignment operators is clearer when you use them to set an argument value in a function call. For example:

median(x = 1:10)
x   
## Error: object 'x' not found

In this case, x is declared within the scope of the function, so it does not exist in the user workspace.

median(x <- 1:10)
x    
## [1]  1  2  3  4  5  6  7  8  9 10

In this case, x is declared in the user workspace, so you can use it after the function call has been completed.

There is a general preference among the R community for using <- for assignment (other than in function signatures) for compatibility with (very) old versions of S-Plus. Note that the spaces help to clarify situations like

x<-3
# Does this mean assignment?
x <- 3
# Or less than?
x < -3

Most R IDEs have keyboard shortcuts to make <- easier to type. Ctrl + = in Architect, Alt + - in RStudio (Option + - under macOS), Shift + - (underscore) in emacs+ESS.

If you prefer writing = to <- but want to use the more common assignment symbol for publicly released code (on CRAN, for example), then you can use one of the tidy_* functions in the formatR package to automatically replace = with <-.

library(formatR)
tidy_source(text = "x=1:5", arrow = TRUE)
## x <- 1:5

The answer to the question "Why does x <- y = 5 throw an error but not x <- y <- 5?" is "It's down to the magic contained in the parser". R's syntax contains many ambiguous cases that have to be resolved one way or another. The parser chooses to resolve the bits of the expression in different orders depending on whether = or <- was used.

To understand what is happening, you need to know that assignment silently returns the value that was assigned. You can see that more clearly by explicitly printing, for example print(x <- 2 + 3).

Secondly, it's clearer if we use prefix notation for assignment. So

x <- 5
`<-`(x, 5)  #same thing

y = 5
`=`(y, 5)   #also the same thing

The parser interprets x <- y <- 5 as

`<-`(x, `<-`(y, 5))

We might expect that x <- y = 5 would then be

`<-`(x, `=`(y, 5))

but actually it gets interpreted as

`=`(`<-`(x, y), 5)

This is because = is lower precedence than <-, as shown on the ?Syntax help page.

Your mock is raising the exception just fine, but the error.resp.status value is missing. Rather than use return_value, just tell Mock that status is an attribute:

barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')

Additional keyword arguments to Mock() are set as attributes on the resulting object.

I put your foo and bar definitions in a my_tests module, added in the HttpError class so I could use it too, and your test then can be ran to success:

>>> from my_tests import foo, HttpError
>>> import mock
>>> with mock.patch('my_tests.bar') as barMock:
...     barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
...     result = my_test.foo()
... 
404 - 
>>> result is None
True

You can even see the print '404 - %s' % error.message line run, but I think you wanted to use error.content there instead; that's the attribute HttpError() sets from the second argument, at any rate.

There is a way that's pretty memory inefficient.

single file:

import hashlib
def file_as_bytes(file):
    with file:
        return file.read()

print hashlib.md5(file_as_bytes(open(full_path, 'rb'))).hexdigest()

list of files:

[(fname, hashlib.md5(file_as_bytes(open(fname, 'rb'))).digest()) for fname in fnamelst]

Recall though, that MD5 is known broken and should not be used for any purpose since vulnerability analysis can be really tricky, and analyzing any possible future use your code might be put to for security issues is impossible. IMHO, it should be flat out removed from the library so everybody who uses it is forced to update. So, here's what you should do instead:

[(fname, hashlib.sha256(file_as_bytes(open(fname, 'rb'))).digest()) for fname in fnamelst]

If you only want 128 bits worth of digest you can do .digest()[:16].

This will give you a list of tuples, each tuple containing the name of its file and its hash.

Again I strongly question your use of MD5. You should be at least using SHA1, and given recent flaws discovered in SHA1, probably not even that. Some people think that as long as you're not using MD5 for 'cryptographic' purposes, you're fine. But stuff has a tendency to end up being broader in scope than you initially expect, and your casual vulnerability analysis may prove completely flawed. It's best to just get in the habit of using the right algorithm out of the gate. It's just typing a different bunch of letters is all. It's not that hard.

Here is a way that is more complex, but memory efficient:

import hashlib

def hash_bytestr_iter(bytesiter, hasher, ashexstr=False):
    for block in bytesiter:
        hasher.update(block)
    return hasher.hexdigest() if ashexstr else hasher.digest()

def file_as_blockiter(afile, blocksize=65536):
    with afile:
        block = afile.read(blocksize)
        while len(block) > 0:
            yield block
            block = afile.read(blocksize)


[(fname, hash_bytestr_iter(file_as_blockiter(open(fname, 'rb')), hashlib.md5()))
    for fname in fnamelst]

And, again, since MD5 is broken and should not really ever be used anymore:

[(fname, hash_bytestr_iter(file_as_blockiter(open(fname, 'rb')), hashlib.sha256()))
    for fname in fnamelst]

Again, you can put [:16] after the call to hash_bytestr_iter(...) if you only want 128 bits worth of digest.

I use the line:

export JAVA_HOME=$(readlink -f $(dirname $(readlink -f $(which java) ))/../)

to my ~/.profile so it uses the base of the default java directory at login time. This is for bash.

You are declaring a local variable, not a class variable. To set an instance variable (attribute), use

class Example(object):
    def the_example(self):
        self.itsProblem = "problem"  # <-- remember the 'self.'

theExample = Example()
theExample.the_example()
print(theExample.itsProblem)

To set a class variable (a.k.a. static member), use

class Example(object):
    def the_example(self):
        Example.itsProblem = "problem"
        # or, type(self).itsProblem = "problem"
        # depending what you want to do when the class is derived.

Async functions are not supported by Node versions older than version 7.6.

You'll need to transpile your code (e.g. using Babel) to a version of JS that Node understands if you are using an older version.

That said, the current (2018) LTS version of Node.js is 8.x, so if you are using an earlier version you should very strongly consider upgrading.

import sys

try:
  print("stuff")
except:
  sys.exit(1) # exiing with a non zero value is better for returning from an error

It's as simple as this:

unsigned int foo;
int bar = 10;

foo = (unsigned int)bar;

Or vice versa...

You have to store the content as a fact:

- set_fact:
    string_to_echo: "{{ command_output.stdout }}"

Rule of three in C++ is a fundamental principle of the design and the development of three requirements that if there is clear definition in one of the following member function, then the programmer should define the other two members functions together. Namely the following three member functions are indispensable: destructor, copy constructor, copy assignment operator.

Copy constructor in C++ is a special constructor. It is used to build a new object, which is the new object equivalent to a copy of an existing object.

Copy assignment operator is a special assignment operator that is usually used to specify an existing object to others of the same type of object.

There are quick examples:

// default constructor
My_Class a;

// copy constructor
My_Class b(a);

// copy constructor
My_Class c = a;

// copy assignment operator
b = a;

window.location.hash = '#tries';

This will scroll to the element in question, essentially "focus"ing it.

Keep() method marks the specified key in the dictionary for retention

You can use Keep() when prevent/hold the value depends on additional logic.

when you read TempData one’s and want to hold for another request then use keep method, so TempData can available for next request as above example.

You should keep class and function definitions organized in files.

Use require_once() to load dependencies (classes, functions, constants).

Use require() to load template-like files.

Use include_once() to load optional dependencies (classes, functions, constants).

Use include() to load optional template-like files.

Plugin eregex.vim handles Perl-style non-greedy operators *? and +?

May be using List comprehension

import pandas as pd
import numpy as np
df=pd.DataFrame(['ONE','Two', np.nan],columns=['Name']})
df['Name'] = [str(i).lower() for i in df['Name']] 

print(df)

Comparison expressions should each be in their own brackets:

{% if (a == 'foo') or (b == 'bar') %}
    ...
{% endif %}

Alternative if you are inspecting a single variable and a number of possible values:

{% if a in ['foo', 'bar', 'qux'] %}
    ...
{% endif %}

You can also use OPENROWSET to import excel file in sql server.

SELECT * INTO Your_Table FROM OPENROWSET('Microsoft.ACE.OLEDB.12.0',
                        'Excel 12.0;Database=C:\temp\MySpreadsheet.xlsx',
                        'SELECT * FROM [Data$]')

UPDATE

In Android Studio Version 3.5 and Above

Now Instant Run is removed, It has "Apply Changes". See official blog for more about the change.

we removed Instant Run and re-architectured and implemented from the ground-up a more practical approach in Android Studio 3.5 called Apply Changes.Apply Changes uses platform-specific APIs from Android Oreo and higher to ensure reliable and consistent behavior; unlike Instant Run, Apply Changes does not modify your APK. To support the changes, we re-architected the entire deployment pipeline to improve deployment speed, and also tweaked the run and deployment toolbar buttons for a more streamlined experience.

Now, As per stable available version 3.0 of Android studio,

If you need to turn off Instant Run, go to

File ? Settings ? Build, Execution, Deployment ? Instant Run and uncheck Enable Instant Run.

For me the problem was the execution of clone via sudo.

If you clone to a directory where you have user permission ( /home/user/git) it will work fine.

(Explanation: Running a command as superuser will not work with the same public key as running a command as user. Therefore Github refused the connection.)

This solution requires a SSH key already to be set up: https://help.github.com/articles/generating-ssh-keys

The way of dknaack does not work for me, I found this solution as well:

@Html.DropDownList("Chapters", ViewBag.Chapters as SelectList, 
                    "Select chapter", new { @onchange = "location = this.value;" })

where

@Html.DropDownList(controlName, ViewBag.property + cast, "Default value", @onchange event)

In the controller you can add:

DbModel db = new DbModel();    //entity model of Entity Framework

ViewBag.Chapters = new SelectList(db.T_Chapter, "Id", "Name");

In order to call this you will have to store a reference to your form and pass the reference to the run method. Then you can call this in an actionhandler.

public partial class Form1 : Form
{
    public void ChangeSize(int width, int height)
    {
        this.Size = new Size(width, height);
    }
}

Create a custom Collector

public static <T> Collector<T, ?, T> toSingleton() {
    return Collectors.collectingAndThen(
            Collectors.toList(),
            list -> {
                if (list.size() != 1) {
                    throw new IllegalStateException();
                }
                return list.get(0);
            }
    );
}

We use Collectors.collectingAndThen to construct our desired Collector by

1. Collecting our objects in a List with the Collectors.toList() collector.
2. Applying an extra finisher at the end, that returns the single element — or throws an IllegalStateException if list.size != 1.

Used as:

User resultUser = users.stream()
        .filter(user -> user.getId() > 0)
        .collect(toSingleton());

You can then customize this Collector as much as you want, for example give the exception as argument in the constructor, tweak it to allow two values, and more.

An alternative — arguably less elegant — solution:

You can use a 'workaround' that involves peek() and an AtomicInteger, but really you shouldn't be using that.

What you could do istead is just collecting it in a List, like this:

LinkedList<User> users = new LinkedList<>();
users.add(new User(1, "User1"));
users.add(new User(2, "User2"));
users.add(new User(3, "User3"));
List<User> resultUserList = users.stream()
        .filter(user -> user.getId() == 1)
        .collect(Collectors.toList());
if (resultUserList.size() != 1) {
    throw new IllegalStateException();
}
User resultUser = resultUserList.get(0);

The below code is a solution to the question in Python 3. Before running the code, make sure you have installed the PyPDF2 library in your environment. If not installed, open the command prompt and run the following command:

pip3 install PyPDF2

Solution Code:

import PyPDF2
pdfFileObject = open('sample.pdf', 'rb')
pdfReader = PyPDF2.PdfFileReader(pdfFileObject)
count = pdfReader.numPages
for i in range(count):
    page = pdfReader.getPage(i)
    print(page.extractText())

Use the constructor Date(year,month,date) in Java 8 it is deprecated:

Date date = new Date(1990, 10, 26, 0, 0);

The best way is to use SimpleDateFormat

DateFormat format = new SimpleDateFormat("dd/MM/yyyy");
Date date = format.parse("26/10/1985");

you need to import import java.text.SimpleDateFormat;

Just ot note: Pycharm's to spaces function only works on indent tabs at the beginning of a line, not interstitial tabs within a line of text. for example, when you are trying to format columns in monospaced text.

truncate tableName

That is what you are looking for.

Truncate will delete all records in the table, emptying it.

Following code works on my machine

1. you probably have something missing in your code.
2. please also check the code files's encoding.

3. make sure you have PIL package installed

   import Tkinter as tk
   from PIL import ImageTk, Image
   
   path = 'C:/xxxx/xxxx.jpg'
   
   root = tk.Tk()
   img = ImageTk.PhotoImage(Image.open(path))
   panel = tk.Label(root, image = img)
   panel.pack(side = "bottom", fill = "both", expand = "yes")
   root.mainloop()
   

AJAX requests are no different from GET and POST requests initiated through a <form> element. Which means you can use $_GET and $_POST to retrieve the data.

When you're making an AJAX request (jQuery example):

// JavaScript file

elements = [1, 2, 9, 15].join(',')
$.post('/test.php', {elements: elements})

It's (almost) equivalent to posting this form:

<form action="/test.php" method="post">
  <input type="text" name="elements" value="1,2,9,15">
</form>

In both cases, on the server side you can read the data from the $_POST variable:

// test.php file

$elements = $_POST['elements'];
$elements = explode(',', $elements);

For the sake of simplicity I'm joining the elements with comma here. JSON serialization is a more universal solution, though.

Steps to install curl in windows

Install cURL on Windows

There are 4 steps to follow to get cURL installed on Windows.

Step 1 and Step 2 is to install SSL library. Step 3 is to install cURL. Step 4 is to install a recent certificate

Step One: Install Visual C++ 2008 Redistributables

From https://www.microsoft.com/en-za/download/details.aspx?id=29 For 64bit systems Visual C++ 2008 Redistributables (x64) For 32bit systems Visual C++ 2008 Redistributables (x32)

Step Two: Install Win(32/64) OpenSSL v1.0.0k Light

From http://www.shininglightpro.com/products/Win32OpenSSL.html For 64bit systems Win64 OpenSSL v1.0.0k Light For 32bit systems Win32 OpenSSL v1.0.0k Light

Step Three: Install cURL

Depending on if your system is 32 or 64 bit, download the corresponding** curl.exe.** For example, go to the Win64 - Generic section and download the Win64 binary with SSL support (the one where SSL is not crossed out). Visit http://curl.haxx.se/download.html

Copy curl.exe to C:\Windows\System32

Step Four: Install Recent Certificates

Do not skip this step. Download a recent copy of valid CERT files from https://curl.haxx.se/ca/cacert.pem Copy it to the same folder as you placed curl.exe (C:\Windows\System32) and rename it as curl-ca-bundle.crt

If you have already installed curl or after doing the above steps, add the directory where it's installed to the windows path:

1 - From the Desktop, right-click My Computer and click Properties.
2 - Click Advanced System Settings .
3 - In the System Properties window click the Environment Variables button.
4 - Select Path and click Edit.
5 - Append ;c:\path to curl directory at the end.
5 - Click OK.
6 - Close and re-open the command prompt

Have you tried using the DataTable.Select(filterExpression, sortExpression) method?

"[a-zA-Z]" matches only one character. To match multiple characters, use "[a-zA-Z]+".

Since a dot is a joker for any character, you have to mask it: "abc\." To make the dot optional, you need a question mark: "abc\.?"

If you write the Pattern as literal constant in your code, you have to mask the backslash:

System.out.println ("abc".matches ("abc\\.?"));
System.out.println ("abc.".matches ("abc\\.?"));
System.out.println ("abc..".matches ("abc\\.?"));

Combining both patterns:

System.out.println ("abc.".matches ("[a-zA-Z]+\\.?"));

Instead of a-zA-Z, \w is often more appropriate, since it captures foreign characters like äöüßø and so on:

System.out.println ("abc.".matches ("\\w+\\.?"));   

For current ActiveRecord (4.2.4+) there is a method to_hash on the Result object that returns an array of hashes. You can then map over it and convert to symbolized hashes:

# Get an array of hashes representing the result (column => value):
result.to_hash
# => [{"id" => 1, "title" => "title_1", "body" => "body_1"},
      {"id" => 2, "title" => "title_2", "body" => "body_2"},
      ...
     ]

result.to_hash.map(&:symbolize_keys)
# => [{:id => 1, :title => "title_1", :body => "body_1"},
      {:id => 2, :title => "title_2", :body => "body_2"},
      ...
     ]

See the ActiveRecord::Result docs for more info.

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes.

Instead you could try the following approach. Change your markup to the following:

<div ng-controller="myAppController" style="text-align:center">
  <p style="font-size:28px;">Enter Quantity:
      <input type="text" ng-model="quantity"/>
  </p>
  <button ng-click="calculateQuantity()">Calculate</button>
  <h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>

Next, update your controller:

myAppModule.controller('myAppController', function($scope,calculateService) {
  $scope.quantity=1;
  $scope.quantityResult = 0;

  $scope.calculateQuantity = function() {
    $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  };
});

Here's a JSBin example that demonstrates the above approach.

The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity changes.

This would involve updating the template to add an ng-change on the input, and an ng-if on the result:

<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>

and

<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>

In the controller add:

$scope.showQuantityResult = false;

$scope.calculateQuantity = function() {
  $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  $scope.showQuantityResult = true;
};

$scope.hideQuantityResult = function() {
  $scope.showQuantityResult = false;
}; 

These updates can be seen in this JSBin demo.

I don't know why this question was reopened but here is a tidyverse option.

x %>% 
  arrange(desc(value)) %>%
  mutate(variable=fct_reorder(variable,value)) %>% 
ggplot(aes(variable,value,fill=variable)) + geom_bar(stat="identity") + 
  scale_y_continuous("",label=scales::percent) + coord_flip() 

If everyone agrees that

1. return is not necessary at the end of a function's body
2. not using return is marginally faster (according to @Alan's test, 4.3 microseconds versus 5.1)

should we all stop using return at the end of a function? I certainly won't, and I'd like to explain why. I hope to hear if other people share my opinion. And I apologize if it is not a straight answer to the OP, but more like a long subjective comment.

My main problem with not using return is that, as Paul pointed out, there are other places in a function's body where you may need it. And if you are forced to use return somewhere in the middle of your function, why not make all return statements explicit? I hate being inconsistent. Also I think the code reads better; one can scan the function and easily see all exit points and values.

Paul used this example:

foo = function() {
 if(a) {
   return(a)
 } else {
   return(b)
 }
}

Unfortunately, one could point out that it can easily be rewritten as:

foo = function() {
 if(a) {
   output <- a
 } else {
   output <- b
 }
output
}

The latter version even conforms with some programming coding standards that advocate one return statement per function. I think a better example could have been:

bar <- function() {
   while (a) {
      do_stuff
      for (b) {
         do_stuff
         if (c) return(1)
         for (d) {
            do_stuff
            if (e) return(2)
         }
      }
   }
   return(3)
}

This would be much harder to rewrite using a single return statement: it would need multiple breaks and an intricate system of boolean variables for propagating them. All this to say that the single return rule does not play well with R. So if you are going to need to use return in some places of your function's body, why not be consistent and use it everywhere?

I don't think the speed argument is a valid one. A 0.8 microsecond difference is nothing when you start looking at functions that actually do something. The last thing I can see is that it is less typing but hey, I'm not lazy.

The scrolling effect is cause by specifying the generic 'background' property in your css instead of the more specific background-image. By setting the background property, the animation will transition between all properties.. Background-Color, Background-Image, Background-Position.. Etc Thus causing the scrolling effect..

E.g.

a {
-webkit-transition-property: background-image 300ms ease-in 200ms;
-moz-transition-property: background-image 300ms ease-in 200ms;
-o-transition-property: background-image 300ms ease-in 200ms;
transition: background-image 300ms ease-in 200ms;
}

First: what the others said. Forget the echo statement and just write your navbar.php as a regular HTML file.

Second: your include paths are probably messed up. To make sure you include files that are in the same directory as the current file, use __DIR__:

include __DIR__.'/navbar.php'; // PHP 5.3 and later
include dirname(__FILE__).'/navbar.php'; // PHP 5.2

You can try something like this:

    <script type="text/javascript">
        function simulateLogin(userName)
        {
            var userNameField = document.getElementById("username");
            userNameField.value = userName;
            var goButton = document.getElementById("go");
            goButton.click();
        }

        simulateLogin("testUser");
</script>

I caught this error a few days ago.

IN my case it was because I was using a Transaction on a Singleton.

.Net does not work well with Singleton as stated above.

My solution was this:

public class DbHelper : DbHelperCore
{
    public DbHelper()
    {
        Connection = null;
        Transaction = null;
    }

    public static DbHelper instance
    {
        get
        {
            if (HttpContext.Current is null)
                return new DbHelper();
            else if (HttpContext.Current.Items["dbh"] == null)
                HttpContext.Current.Items["dbh"] = new DbHelper();

            return (DbHelper)HttpContext.Current.Items["dbh"];
        }
    }

    public override void BeginTransaction()
    {
        Connection = new SqlConnection(Entity.Connection.getCon);
        if (Connection.State == System.Data.ConnectionState.Closed)
            Connection.Open();
        Transaction = Connection.BeginTransaction();
    }
}

I used HttpContext.Current.Items for my instance. This class DbHelper and DbHelperCore is my own class

What is the difference between Attribute and Property?
What is the difference between Feature and Function? What is the difference between Characteristic and Character? What is the difference between Act and Behavior?

Its just a change in context.

Neither of the answers resolved the issue for me. Even after I had installed a new version of Tortoise SVN + Ccleaner.

Seems that there is a folder in AppData\Roaming\Subversion that contains all configuration of Tortoise SVN. You need to delete it all and restart Tortoise SVN.

There is also the MATLAB Engine for Python by MathWorks itself. If you have MATLAB, this might be worth considering (I haven't tried it myself but it has a lot more functionality than just reading MATLAB files). However, I don't know if it is allowed to distribute it to other users (it is probably not a problem if those persons have MATLAB. Otherwise, maybe NumPy is the right way to go?).

Also, if you want to do all the basics yourself, MathWorks provides (if the link changes, try to google for matfile_format.pdf or its title MAT-FILE Format) a detailed documentation on the structure of the file format. It's not as complicated as I personally thought, but obviously, this is not the easiest way to go. It also depends on how many features of the .mat-files you want to support.

I've written a "small" (about 700 lines) Python script which can read some basic .mat-files. I'm neither a Python expert nor a beginner and it took me about two days to write it (using the MathWorks documentation linked above). I've learned a lot of new stuff and it was quite fun (most of the time). As I've written the Python script at work, I'm afraid I cannot publish it... But I can give some advice here:

• First read the documentation.
• Use a hex editor (such as HxD) and look into a reference .mat-file you want to parse.
• Try to figure out the meaning of each byte by saving the bytes to a .txt file and annotate each line.
• Use classes to save each data element (such as miCOMPRESSED, miMATRIX, mxDOUBLE, or miINT32)
• The .mat-files' structure is optimal for saving the data elements in a tree data structure; each node has one class and subnodes

if you have this already and use jquery this will be your answer:

$($(this)[0].selectedOptions[0]).text()

T(n)=T(n/2)+1

T(n/2)= T(n/4)+1+1

Put the value of The(n/2) in above so T(n)=T(n/4)+1+1 . . . . T(n/2^k)+1+1+1.....+1

=T(2^k/2^k)+1+1....+1 up to k

=T(1)+k

As we taken 2^k=n

K = log n

So Time complexity is O(log n)

No need to re-assign.

Vincent, I'll answer again using your new requirements. Since you don't care about the content being hidden if it's too long, you don't need to float the header. Just put overflow hidden on the html and body tags, and set #content height to 100%. The content will always be longer than the viewport by the height of the header, but it'll be hidden and won't cause scrollbars.

From the PHP Manual:

Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:

mysqli_connect()

PDO::__construct()

use MySQLi or PDO

<?php
$con = mysqli_connect('localhost', 'username', 'password', 'database');

When you want to check the condition at the beginning of the loop, simply negate the condition on a standard while loop:

while(!cond) { ... }

If you need it at the end, use a do ... while loop and negate the condition:

do { ... } while(!cond);

How about this:

find /some/directory -maxdepth 1 -type f -exec cmd option {} \; > results.out

• -maxdepth 1 argument prevents find from recursively descending into any subdirectories. (If you want such nested directories to get processed, you can omit this.)
• -type -f specifies that only plain files will be processed.
• -exec cmd option {} tells it to run cmd with the specified option for each file found, with the filename substituted for {}
• \; denotes the end of the command.
• Finally, the output from all the individual cmd executions is redirected to results.out

However, if you care about the order in which the files are processed, you might be better off writing a loop. I think find processes the files in inode order (though I could be wrong about that), which may not be what you want.

you have to import this files into the <head></head> of your html.

In case you get this error message in this situation:

• using github for entreprise
• using credential.helper=wincred in git config
• using your windows credentials which you changed recently

Then look at this answer: https://stackoverflow.com/a/39608906/521257

Windows stores credentials in a credentials manager, clear it or update it.

There are two steps:

1. Convert interface to JSON Byte
2. Convert JSON Byte to struct

Below is an example:

dbByte, _ := json.Marshal(dbContent)
_ = json.Unmarshal(dbByte, &MyStruct)

In window 10 there is already a path present in env as C:\>ProgramData\Oracle\Java\javapath that holds symlinks to the executables.

When I install a new version and remove that from my environment variable, my all project start showing it.

I am using eclipse oxygen in window 10

To resolve it:-

1. I just remove path C:\>ProgramData\Oracle\Java\javapath from environment variable and added new env as JAVA_HOME and %JAVA_HOME%/bin in path

2. I reinstall the jdk with admin privileges (delete the previous JRE folder)

3. Open your eclipse project > right click > Goto Proprieties> In Libraries > Now remove JRE System Library > Click on Add Library > select "JRE System Library" > Click on Next > Select "Workspace default JRE(jre1.8.x_xxx)" > finish

My issue is resolved :) Hope it will help you :)

Since the text that you are escaping will appear in an HTML attribute, you must be sure to escape not only HTML entities but also HTML attributes:

var ESC_MAP = {
    '&': '&',
    '<': '&lt;',
    '>': '&gt;',
    '"': '&quot;',
    "'": '&#39;'
};

function escapeHTML(s, forAttribute) {
    return s.replace(forAttribute ? /[&<>'"]/g : /[&<>]/g, function(c) {
        return ESC_MAP[c];
    });
}

Then, your escaping code becomes var user_id = escapeHTML(id, true).

For more information, see Foolproof HTML escaping in Javascript.

You can continue chaining them like you've done.

results = results.Where (o => o.OrderStatus == OrderStatus.Open);
results = results.Where (o => o.InvoicePaid);

This represents an AND.

Java 8 and above

Using Java 8+ lambda expressions, if you have a class or interface with only a single abstract method (sometimes called a SAM type), for example:

public interface MyInterface {
    String doSomething(int param1, String param2);
}

then anywhere where MyInterface is used, you can substitute a lambda expression:

class MyClass {
    public MyInterface myInterface = (p1, p2) -> { return p2 + p1; };
}

For example, you can create a new thread very quickly:

new Thread(() -> someMethod()).start();

And use the method reference syntax to make it even cleaner:

new Thread(this::someMethod).start();

Without lambda expressions, these last two examples would look like:

new Thread(new Runnable() { someMethod(); }).start();

Before Java 8

A common pattern would be to 'wrap' it within an interface, like Callable, for example, then you pass in a Callable:

public T myMethod(Callable<T> func) {
    return func.call();
}

This pattern is known as the Command Pattern.

Keep in mind you would be best off creating an interface for your particular usage. If you chose to go with callable, then you'd replace T above with whatever type of return value you expect, such as String.

In response to your comment below you could say:

public int methodToPass() { 
        // do something
}

public void dansMethod(int i, Callable<Integer> myFunc) {
       // do something
}

then call it, perhaps using an anonymous inner class:

dansMethod(100, new Callable<Integer>() {
   public Integer call() {
        return methodToPass();
   }
});

Keep in mind this is not a 'trick'. It's just java's basic conceptual equivalent to function pointers.

The .NET garbage collector takes care of all this for you.

It is able to determine when objects are no longer referenced and will (eventually) free the memory that had been allocated to them.

grid is not a global, it is local to the main function. Change this:

int nonrecursivecountcells(color[ROW_SIZE][COL_SIZE], int row, int column)

to this:

int nonrecursivecountcells(color grid[ROW_SIZE][COL_SIZE], int row, int column)

Basically you forgot to give that first param a name, grid will do since it matches your code.

• Context Menu key (one one with the menu on it, next to the right Windows key)
• Then choose "Resolve" from the menu. That can be done by pressing "s".

Regular javascript can be used to trap the backspace key. You can use the event.keyCode method. The keycode is 8, so the code would look something like this:

if (event.keyCode == 8) {
    // Do stuff...
}

If you want to check for both the [delete] (46) as well as the [backspace] (8) keys, use the following:

if (event.keyCode == 8 || event.keyCode == 46) {
    // Do stuff...
}

Both if (one.length() > 0) {} and if (!"".equals(one)) {} will check against an empty foo parameter, and an empty parameter is what you'd get if the the form is submitted with no value in the foo text field.

If there's any chance you can use the Expression Language to handle the parameter, you could access it with empty param.foo in an expression.

<c:if test='${not empty param.foo}'>
    This page code gets rendered.
</c:if>

BUT WHY try to set $_session with js? any JS variable can be modified by a player with some 3rd party tools (firebug), thus any player can mod the $_session[]! And PHP cant give js any secret codes (or even [rolling] encrypted) to return, it is all visible. Jquery or AJAX can't help, it's all js in the end.

This happens in online game design a lot. (Maybe a bit of Game Theory? forgive me, I have a masters and love to put theory to use :) ) Like in crimegameonline.com, I initialize a minigame puzzle with PHP, saving the initial board in $_SESSION['foo']. Then, I use php to [make html that] shows the initial puzzle start. Then, js takes over, watching buttons and modding element xy's as players make moves. I DONT want to play client-server (like WOW) and ask the server 'hey, my player want's to move to xy, what should I do?'. It's a lot of bandwidth, I don't want the server that involved.

And I can just send POSTs each time the player makes an error (or dies). The player can block outgoing POSTs (and alter local JS vars to make it forget the out count) or simply modify outgoing POST data. YES, people will do this, especially if real money is involved.

If the game is small, you could send post updates EACH move (button click), 1-way, with post vars of the last TWO moves. Then, the server sanity checks last and cats new in a $_SESSION['allMoves']. If the game is massive, you could just send a 'halfway' update of all preceeding moves, and see if it matches in the final update's list.

Then, after a js thinks we have a win, add or mod a button to change pages:

document.getElementById('but1').onclick=Function("leave()");
...
function leave() {
    var line='crimegameonline-p9b.php';
    top.location.href=line;
}

Then the new page's PHP looks at $_SESSION['init'] and plays thru each of the $_SESSION['allMoves'] to see if it is really a winner. The server (PHP) must decide if it is really a winner, not the client (js).

All hover is doing behind the scenes is binding to the mouseover and mouseout property. I would bind and unbind your functions from those events individually.

For example, say you have the following html:

<a href="#" class="myLink">Link</a>

then your jQuery would be:

$(document).ready(function() {

  function mouseOver()
  {
    $(this).css('color', 'red');
  }
  function mouseOut()
  {
    $(this).css('color', 'blue');
  }

  // either of these might work
  $('.myLink').hover(mouseOver, mouseOut); 
  $('.myLink').mouseover(mouseOver).mouseout(mouseOut); 
  // otherwise use this
  $('.myLink').bind('mouseover', mouseOver).bind('mouseout', mouseOut);


  // then to unbind
  $('.myLink').click(function(e) {
    e.preventDefault();
    $('.myLink').unbind('mouseover', mouseOver).unbind('mouseout', mouseOut);
  });

});

Be aware, IBOutletCollection should be @property (strong, nonatomic).

You have Integer#to_s(base) and String#to_i(base) available to you.

Integer#to_s(base) converts a decimal number to a string representing the number in the base specified:

9.to_s(2) #=> "1001"

while the reverse is obtained with String#to_i(base):

"1001".to_i(2) #=> 9

You can also do //div[@id='..' or @class='...] and you can have parenthesized expressions inside //div[@id='..' and (@class='a' or @class='b')].

(I) Super Key – An attribute or a combination of attribute that is used to identify the records uniquely is known as Super Key. A table can have many Super Keys.

E.g. of Super Key

1. ID
2. ID, Name
3. ID, Address
4. ID, Department_ID
5. ID, Salary
6. Name, Address
7. Name, Address, Department_ID

So on as any combination which can identify the records uniquely will be a Super Key.

(II) Candidate Key – It can be defined as minimal Super Key or irreducible Super Key. In other words an attribute or a combination of attribute that identifies the record uniquely but none of its proper subsets can identify the records uniquely.

E.g. of Candidate Key

1. ID
2. Name, Address

For above table we have only two Candidate Keys (i.e. Irreducible Super Key) used to identify the records from the table uniquely. ID Key can identify the record uniquely and similarly combination of Name and Address can identify the record uniquely, but neither Name nor Address can be used to identify the records uniquely as it might be possible that we have two employees with similar name or two employees from the same house.

(III) Primary Key – A Candidate Key that is used by the database designer for unique identification of each row in a table is known as Primary Key. A Primary Key can consist of one or more attributes of a table.

E.g. of Primary Key - Database designer can use one of the Candidate Key as a Primary Key. In this case we have “ID” and “Name, Address” as Candidate Key, we will consider “ID” Key as a Primary Key as the other key is the combination of more than one attribute.

(IV) Foreign Key – A foreign key is an attribute or combination of attribute in one base table that points to the candidate key (generally it is the primary key) of another table. The purpose of the foreign key is to ensure referential integrity of the data i.e. only values that are supposed to appear in the database are permitted.

E.g. of Foreign Key – Let consider we have another table i.e. Department Table with Attributes “Department_ID”, “Department_Name”, “Manager_ID”, ”Location_ID” with Department_ID as an Primary Key. Now the Department_ID attribute of Employee Table (dependent or child table) can be defined as the Foreign Key as it can reference to the Department_ID attribute of the Departments table (the referenced or parent table), a Foreign Key value must match an existing value in the parent table or be NULL.

(V) Composite Key – If we use multiple attributes to create a Primary Key then that Primary Key is called Composite Key (also called a Compound Key or Concatenated Key).

E.g. of Composite Key, if we have used “Name, Address” as a Primary Key then it will be our Composite Key.

(VI) Alternate Key – Alternate Key can be any of the Candidate Keys except for the Primary Key.

E.g. of Alternate Key is “Name, Address” as it is the only other Candidate Key which is not a Primary Key.

(VII) Secondary Key – The attributes that are not even the Super Key but can be still used for identification of records (not unique) are known as Secondary Key.

E.g. of Secondary Key can be Name, Address, Salary, Department_ID etc. as they can identify the records but they might not be unique.

There is no explicit way to change the favicon globally using CSS that I know of. But you can use a simple trick to change it on the fly.

First just name, or rename, the favicon to "favicon.ico" or something similar that will be easy to remember, or is relevant for the site you're working on. Then add the link to the favicon in the head as you usually would. Then when you drop in a new favicon just make sure it's in the same directory as the old one, and that it has the same name, and there you go!

It's not a very elegant solution, and it requires some effort. But dropping in a new favicon in one place is far easier than doing a find and replace of all the links, or worse, changing them manually. At least this way doesn't involve messing with the code.

Of course dropping in a new favicon with the same name will delete the old one, so make sure to backup the old favicon in case of disaster, or if you ever want to go back to the old design.

java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to [Ljava.lang.Integer;

you try to cast an Array of Object to cast into Array of Integer. You cant do it. This type of downcast is not permitted.

You can make an array of Integer, and after that copy every value of the first array into second array.

Now this may include more than you need (and may not even work for command line applications in a non-graphical environment, I don't know), but there is nw.js. It's Blink (i.e. Chromium/Webkit) + io.js (i.e. Node.js).

You can use node-webkit-builder to build native executable binaries for Linux, OS X and Windows.

If you want a GUI, that's a huge plus. You can build one with web technologies. If you don't, specify "node-main" in the package.json (and probably "window": {"show": false} although maybe it works to just have a node-main and not a main)

I haven't tried to use it in exactly this way, just throwing it out there as a possibility. I can say it's certainly not an ideal solution for non-graphical Node.js applications.

As quoted above, "If you don't test your private methods, how do you know they won't break?"

This is a major issue. One of the big points of unit tests is to know where, when, and how something broke ASAP. Thus decreasing a significant amount of development & QA effort. If all that is tested is the public, then you don't have honest coverage and delineation of the internals of the class.

I've found one of the best ways to do this is simply add the test reference to the project and put the tests in a class parallel to the private methods. Put in the appropriate build logic so that the tests don't build into the final project.

Then you have all the benefits of having these methods tested and you can find problems in seconds versus minutes or hours.

So in summary, yes, unit test your private methods.

@AlaxDean's #7 answer, Argonaut is the only one that I was able to get working quickly with sbt and intellij. Actually json4s also took little time but dealing with a raw AST is not what I wanted. I got argonaut to work by putting in a single line into my build.st:

libraryDependencies += "io.argonaut" %% "argonaut" % "6.0.1"

And then a simple test to see if it I could get JSON:

package mytest


import scalaz._, Scalaz._
import argonaut._, Argonaut._

object Mytest extends App {

  val requestJson  =
    """
    {
      "userid": "1"
    }
    """.stripMargin

  val updatedJson: Option[Json] = for {
    parsed <- requestJson.parseOption
  } yield ("name", jString("testuser")) ->: parsed

  val obj = updatedJson.get.obj
  printf("Updated user: %s\n", updatedJson.toString())
  printf("obj : %s\n", obj.toString())
  printf("userid: %s\n", obj.get.toMap("userid"))
}

And then

$ sbt
> run
Updated user: Some({"userid":"1","name":"testuser"})
obj : Some(object[("userid","1"),("name","testuser")])
userid: "1"

Make sure you are familiar with Option which is just a value that can also be null (null safe I guess). Argonaut makes use of Scalaz so if you see something you don't understand like the symbol \/ (an or operation) it's probably Scalaz.

How to create database in MySQL Workbench 6.3

(I was going to leave this as a comment on @jldupont's answer, but I don't have enough reputation.)

I've seen answers like @jldupont's answer in other places as well. FWIW, I think it's important to note that this:

except Exception as e:
    print(e)

will print the error output to sys.stdout by default. A more appropriate approach to error handling in general would be:

except Exception as e:
    print(e, file=sys.stderr)

(Note that you have to import sys for this to work.) This way, the error is printed to STDERR instead of STDOUT, which allows for the proper output parsing/redirection/etc. I understand that the question was strictly about 'printing an error', but it seems important to point out the best practice here rather than leave out this detail that could lead to non-standard code for anyone who doesn't eventually learn better.

I haven't used the traceback module as in Cat Plus Plus's answer, and maybe that's the best way, but I thought I'd throw this out there.

I will add my own version, based on the answers here, just for reference. My code takes into consideration sizeof(char) and adds a few comments to it.

// Open the file in read mode.
FILE *file = fopen(file_name, "r");
// Check if there was an error.
if (file == NULL) {
    fprintf(stderr, "Error: Can't open file '%s'.", file_name);
    exit(EXIT_FAILURE);
}
// Get the file length
fseek(file, 0, SEEK_END);
long length = ftell(file);
fseek(file, 0, SEEK_SET);
// Create the string for the file contents.
char *buffer = malloc(sizeof(char) * (length + 1));
buffer[length] = '\0';
// Set the contents of the string.
fread(buffer, sizeof(char), length, file);
// Close the file.
fclose(file);
// Do something with the data.
// ...
// Free the allocated string space.
free(buffer);

First of all, create a Github account and project in Github. Go to the root folder and follow steps.

The most important thing we forgot here is ignoring the file. Every time we run Gradle or build it creates new files that are changeable from build to build and pc to pc. We do not want all the files from Android Studio to be added to Git. Files like generated code, binary files (executables) should not be added to Git (version control). So please use .gitignore file while uploading projects to Github. It also reduces the size of the project uploaded to the server.

1. Go to root folder.
2. git init

3. Create .gitignore txt file in root folder. Place these content in the file. (this step not required if the file is auto-generated)

   *.iml .gradle /local.properties /.idea/workspace.xml /.idea/libraries .idea .DS_Store /build /captures .externalNativeBuild

4. git add .
5. git remote add origin https://github.com/username/project.git
6. git commit - m "My First Commit"
7. git push -u origin master

Note : As per suggestion from different developers, they always suggest to use git from the command line. It is up to you.

You need to alias the subquery. Thus, your statement should be:

Select Z.id
From    (
        Select id, time
        From dbo.tablea
        Union All
        Select id, time
        From dbo.tableb
        ) As Z
Group By Z.id

I want to import existing maven project into eclipse. I found 2 ways to do it, one is through running from command line mvn eclipse:eclipse and another is to install maven eclipse plugin from eclipse. What is the difference between the both and which one is preferable?

The maven-eclipse-plugin is a Maven plugin and has always been there (one of the first plugin available with Maven 1, one of the first plugin migrated to Maven 2). It has been during a long time the only decent way to integrateimport an existing maven project with Eclipse. Actually, it doesn't provide real integration, it just generates the .project and .classpath files (it has also WTP support) from a Maven project. I've used this plugin during years and was very happy with it (and very unsatisfied at this time by Eclipse plugins for Maven like m2eclipse).

The m2eclipse plugin is one of the Eclipse plugins for Maven. It's actually the first and most mature of the projects aimed at integrating Maven within the Eclipse IDE (this has not always been the case, it was not really usable ~2 years ago, see the feedback in Mevenide vs. M2Eclipse, Q for Eclipse/IAM). But, even if I do not use things like creating a Maven project from Eclipse or the POM editor or other fancy wizards, I have to say that this plugin is now totally usable, provides very smooth integration, has nice features... In other words, I finally switched to it :) I'd now recommend it to any user (advanced or beginners).

If I install maven eclipse plugin through the eclipse menu Help -> Install New Software, do I still need to modify my pom.xml to include the maven eclipse plugin in the plugins section?

This question is a bit confusing but the answer is no. With the m2eclipse plugin installed, just right-click the package explorer and Import... > Maven projects to import an existing maven project into Eclipse.

Like explained in other answers you need to provide a comparison function. If you would like to keep the definition of that function close to the sort call (e.g. if it only makes sense for this sort) you can define it right there with boost::lambda. Use boost::lambda::bind to call the member function.

To e.g. sort by member variable or function data1:

#include <algorithm>
#include <vector>
#include <boost/lambda/bind.hpp>
#include <boost/lambda/lambda.hpp>
using boost::lambda::bind;
using boost::lambda::_1;
using boost::lambda::_2;

std::vector<myclass> object(10000);
std::sort(object.begin(), object.end(),
    bind(&myclass::data1, _1) < bind(&myclass::data1, _2));

You can import svg and it use it like a image

import chatSVG from '../assets/images/undraw_typing_jie3.svg'

And ise it in img tag

<img src={chatSVG} className='iconChat' alt="Icon chat"/>

You have a constructor which takes 2 parameters. You should write something like:

new ErrorEventArg(errorMsv, lastQuery)

It's less code and easier to read.

EDIT

Or, in order for your way to work, you can try writing a default constructor for ErrorEventArg which would have no parameters, like this:

public ErrorEventArg() {}

Here's a succinct and generic solution to use a seaborn color palette.

First find a color palette you like and optionally visualize it:

sns.palplot(sns.color_palette("Set2", 8))

Then you can use it with matplotlib doing this:

# Unique category labels: 'D', 'F', 'G', ...
color_labels = df['color'].unique()

# List of RGB triplets
rgb_values = sns.color_palette("Set2", 8)

# Map label to RGB
color_map = dict(zip(color_labels, rgb_values))

# Finally use the mapped values
plt.scatter(df['carat'], df['price'], c=df['color'].map(color_map))

As stated by @Will, the decay happens during the parameter passing. One way to get around it is to pass the number of elements. To add onto this, you may find the _countof() macro useful - it does the equivalent of what you've done ;)

.centerDiv {
    position: absolute;
    left: 0;
    right: 0;
    margin: 0 auto;
    text-align:center;
}

I've read this whole thread, and I just want to point out what seems like an inconsistency to me.

The compiler prevents you from doing the assignment with Lists:

List<Tiger> myTigersList = new List<Tiger>() { new Tiger(), new Tiger(), new Tiger() };
List<Animal> myAnimalsList = myTigersList;    // Compiler error

But the compiler is perfectly fine with arrays:

Tiger[] myTigersArray = new Tiger[3] { new Tiger(), new Tiger(), new Tiger() };
Animal[] myAnimalsArray = myTigersArray;    // No problem

The argument about whether the assignment is known to be safe falls apart here. The assignment I did with the array is not safe. To prove that, if I follow that up with this:

myAnimalsArray[1] = new Giraffe();

I get a runtime exception "ArrayTypeMismatchException". How does one explain this? If the compiler really wants to prevent me from doing something stupid, it should have prevented me from doing the array assignment.

I know this is an old question, but this solution has not been mentioned yet, hopefully it may help someone even today, after 8 years.

So, what about wrapping a wrapper? Let's assume one cannot change the decorator neither decorate those methods in init (they may be @property decorated or whatever). There is always a possibility to create custom, class-specific decorator that will capture self and subsequently call the original decorator, passing runtime attribute to it.

Here is a working example (f-strings require python 3.6):

import functools

# imagine this is at some different place and cannot be changed
def check_authorization(some_attr, url):
        def decorator(func):
                @functools.wraps(func)
                def wrapper(*args, **kwargs):
                        print(f"checking authorization for '{url}'...")
                        return func(*args, **kwargs)
                return wrapper
        return decorator

# another dummy function to make the example work
def do_work():
        print("work is done...")

###################
# wrapped wrapper #
###################
def custom_check_authorization(some_attr):
        def decorator(func):
                # assuming this will be used only on this particular class
                @functools.wraps(func)
                def wrapper(self, *args, **kwargs):
                        # get url
                        url = self.url
                        # decorate function with original decorator, pass url
                        return check_authorization(some_attr, url)(func)(self, *args, **kwargs)
                return wrapper
        return decorator
        
#############################
# original example, updated #
#############################
class Client(object):
        def __init__(self, url):
                self.url = url
    
        @custom_check_authorization("some_attr")
        def get(self):
                do_work()

# create object
client = Client(r"https://stackoverflow.com/questions/11731136/class-method-decorator-with-self-arguments")

# call decorated function
client.get()

output:

$date_old = '23-5-2016 23:15:23';

The reason why your full-width-div doesn't stretch 100% to your screen it's because of its parent "container" which occupies only about 80% of the screen.

If you want to make it stretch 100% to the screen either you make the "full-width-div" position fixed or use the "container-fluid" class instead of "container".

There is a package called eclipse-cdt in the Ubuntu 12.10 repositories, this is what you want. If you haven't got g++ already, you need to install that as well, so all you need is:

sudo apt-get install eclipse eclipse-cdt g++

Whether you messed up your system with your previous installation attempts depends heavily on how you did it. If you did it the safe way for trying out new packages not from repositories (i.e., only installed in your home folder, no sudos blindly copied from installation manuals...) you're definitely fine. Otherwise, you may well have thousands of stray files all over your file system now. In that case, run all uninstall scripts you can find for the things you installed, then install using apt-get and hope for the best.

If you use native sql, you can refer to my code, otherwise just ignore my answer.

SELECT * FROM table WHERE tags LIKE "%banana%";

from sqlalchemy import text

bar_tags = "banana"

# '%' attention to spaces
query_sql = """SELECT * FROM table WHERE tags LIKE '%' :bar_tags '%'"""

# db is sqlalchemy session object
tags_res_list = db.execute(text(query_sql), {"bar_tags": bar_tags}).fetchall()

Function

Public Function ArrayLen(arr As Variant) As Integer
    ArrayLen = UBound(arr) - LBound(arr) + 1
End Function

Usage

Dim arr(1 To 3) As String  ' Array starting at 1 instead of 0: nightmare fuel
Debug.Print ArrayLen(arr)  ' Prints 3.  Everything's going to be ok.

Setting

dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

will prevent dialog to cast a shadow.

Solution is to use

dialog.getWindow().setBackgroundDrawableResource(R.drawable.dialog_rounded_background);

where is R.drawable.dialog_rounded_background

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <shape android:shape="rectangle" android:padding="10dp">
            <solid
                android:color="@color/dialog_bg_color"/>
            <corners
                android:radius="30dp" />
        </shape>
    </item>

</layer-list>

Yet another alternative: 

Select FORMAT(date,'MM.yy')
...
...
group by FORMAT(date,'MM.yy')

This is one way to do it:

string = "this is a string"
ssplit = string.split()
for word in ssplit:
    print (word)

Output:

this
is
a
string

The code below was tested on iPhone, iPad (iOS13), Safari (Catalina). It was able to autoplay the YouTube video on all devices. Make sure the video is muted and the playsinline parameter is on. Those are the magic parameters that make it work.

I had the same problem when I submitted data using jQuery AJAX:

$.ajax({
   url:...
   success:function(data){
      //server response's data is JSON
      //I use jQuery's parseJSON method 
      $.parseJSON(data);//it's ERROR
   }
});

If the response is JSON, and you use this method, the data you get is a JavaScript object, but if you use dataType:"text", data is a JSON string. Then the use of $.parseJSON is okay.

Try this,

<?php  if ( ($cart->count_product) > 0) { ?>
         <div class="my_class"><?php print $cart->count_product; ?></div>
<?php } else { 
          print ''; 
}  ?>

Another option is where you have tables like 'type' or 'status', for example, OrderStatus, where you always want to control the Id value, create the Id (Primary Key) column without it being an Identity column is the first place.

If this isn't a good solution for any reason, please let me know. It worked fine for me.

What I did is to hide the Sidebar and then make appear the navbar with breakpoints

@media screen and (max-width: 771px) {
    #fixed-sidebar {
        display: none;
    }
    #navbar-superior {
        display: block !important;
    }
}

Heredoc may be an option, see example 2 here: http://php.net/manual/en/language.types.string.php

i have resolved this by following steps.

1) Go to customise icon in the top right corner chrome.
2) click on more tools option.
3) Click task manager.
4) Kill/end process GPU process

This has resolved my issue of black screen in chrome.

I think you're looking for export - though I could be wrong.. I've never played with tcsh before. Use the following syntax:

export VARIABLE=value

These are automatic variables, like $null, $true, $false etc.

about_Automatic_Variables, see https://technet.microsoft.com/en-us/library/hh847768.aspx?f=255&MSPPError=-2147217396

$NULL
$null is an automatic variable that contains a NULL or empty value. You can use this variable to represent an absent or undefined value in commands and scripts.

Windows PowerShell treats $null as an object with a value, that is, as an explicit placeholder, so you can use $null to represent an empty value in a series of values.

For example, when $null is included in a collection, it is counted as one of the objects.

C:\PS> $a = ".dir", $null, ".pdf"
C:\PS> $a.count
3

If you pipe the $null variable to the ForEach-Object cmdlet, it generates a value for $null, just as it does for the other objects.

PS C:\ps-test> ".dir", $null, ".pdf" | Foreach {"Hello"}
Hello
Hello
Hello

As a result, you cannot use $null to mean "no parameter value." A parameter value of $null overrides the default parameter value.

However, because Windows PowerShell treats the $null variable as a placeholder, you can use it scripts like the following one, which would not work if $null were ignored.

$calendar = @($null, $null, “Meeting”, $null, $null, “Team Lunch”, $null)
$days = Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"
$currentDay = 0

foreach($day in $calendar)
{
    if($day –ne $null)
    {
        "Appointment on $($days[$currentDay]): $day"
    }

    $currentDay++
}

output:

Appointment on Tuesday: Meeting
Appointment on Friday: Team lunch

void main ()
 {
    int temp,integer,count=0,i,cnd=0;
    char ascii[10]={0};
    printf("enter a number");
    scanf("%d",&integer);
     if(integer>>31)
     {
     /*CONVERTING 2's complement value to normal value*/    
     integer=~integer+1;    
     for(temp=integer;temp!=0;temp/=10,count++);    
     ascii[0]=0x2D;
     count++;
     cnd=1;
     }
     else
     for(temp=integer;temp!=0;temp/=10,count++);    
     for(i=count-1,temp=integer;i>=cnd;i--)
     {

        ascii[i]=(temp%10)+0x30;
        temp/=10;
     }
    printf("\n count =%d ascii=%s ",count,ascii);

 }

In the case of RStudio for Windows I succeeded in changing the language following the instructions found in R for Windows FAQ, in particular I wrote:

language = EN

inside the file Rconsole (in my installation it is C:\Program Files\R\R-2.15.2\etc\Rconsole); this works also for the command Rscript.

For example you can locate the Rconsole file with this two commands from a command prompt:

cd \

dir Rconsole /s

The first one make the root as the current directory, the second one looks for the Rconsole file.

In the following screenshot you have that Rconsole file is in the folder C:\Program Files\R\R-3.4.1\etc.

You may have more than one location, in that case you may edit all the Rconsole files.

After that you can open the Rconsole file with your favorite editor and look for the line language = and then append EN at the end of that line.

In the following screenshot the interesting line is the number 70 and you have to append EN at the end of it.

**It is Simple, just follow 2 steps. Step #1. Fire query "Delete from tableName", It will delete all records from table.

Step #2. There is table named "sqlite_sequence" in Sqlite Database, just browse it and you can set sequence table wise to "0" so it will start from auto id "1".** See the screenshot attached.

As this Spring's Jira ticket, it is an intentional design. But the following code works for me.

public static Map<String, Object> getAllKnownProperties(Environment env) {
    Map<String, Object> rtn = new HashMap<>();
    if (env instanceof ConfigurableEnvironment) {
        for (PropertySource<?> propertySource : ((ConfigurableEnvironment) env).getPropertySources()) {
            if (propertySource instanceof EnumerablePropertySource) {
                for (String key : ((EnumerablePropertySource) propertySource).getPropertyNames()) {
                    rtn.put(key, propertySource.getProperty(key));
                }
            }
        }
    }
    return rtn;
}

You can try RuneCountInString from the utf8 package.

returns the number of runes in p

that, as illustrated in this script: the length of "World" might be 6 (when written in Chinese: "??"), but its rune count is 2:

package main
    
import "fmt"
import "unicode/utf8"
    
func main() {
    fmt.Println("Hello, ??", len("??"), utf8.RuneCountInString("??"))
}

Phrozen adds in the comments:

Actually you can do len() over runes by just type casting.
len([]rune("??")) will print 2. At leats in Go 1.3.

And with CL 108985 (May 2018, for Go 1.11), len([]rune(string)) is now optimized. (Fixes issue 24923)

The compiler detects len([]rune(string)) pattern automatically, and replaces it with for r := range s call.

Adds a new runtime function to count runes in a string. Modifies the compiler to detect the pattern len([]rune(string)) and replaces it with the new rune counting runtime function.

RuneCount/lenruneslice/ASCII        27.8ns ± 2%  14.5ns ± 3%  -47.70%
RuneCount/lenruneslice/Japanese     126ns ± 2%   60  ns ± 2%  -52.03%
RuneCount/lenruneslice/MixedLength  104ns ± 2%   50  ns ± 1%  -51.71%

Stefan Steiger points to the blog post "Text normalization in Go"

What is a character?

As was mentioned in the strings blog post, characters can span multiple runes.
For example, an 'e' and '?´?´' (acute "\u0301") can combine to form 'é' ("e\u0301" in NFD). Together these two runes are one character.

The definition of a character may vary depending on the application.
For normalization we will define it as:

• a sequence of runes that starts with a starter,
• a rune that does not modify or combine backwards with any other rune,
• followed by possibly empty sequence of non-starters, that is, runes that do (typically accents).

The normalization algorithm processes one character at at time.

Using that package and its Iter type, the actual number of "character" would be:

package main
    
import "fmt"
import "golang.org/x/text/unicode/norm"
    
func main() {
    var ia norm.Iter
    ia.InitString(norm.NFKD, "école")
    nc := 0
    for !ia.Done() {
        nc = nc + 1
        ia.Next()
    }
    fmt.Printf("Number of chars: %d\n", nc)
}

Here, this uses the Unicode Normalization form NFKD "Compatibility Decomposition"

Oliver's answer points to UNICODE TEXT SEGMENTATION as the only way to reliably determining default boundaries between certain significant text elements: user-perceived characters, words, and sentences.

For that, you need an external library like rivo/uniseg, which does Unicode Text Segmentation.

That will actually count "grapheme cluster", where multiple code points may be combined into one user-perceived character.

package uniseg
    
import (
    "fmt"
    
    "github.com/rivo/uniseg"
)
    
func main() {
    gr := uniseg.NewGraphemes("!")
    for gr.Next() {
        fmt.Printf("%x ", gr.Runes())
    }
    // Output: [1f44d 1f3fc] [21]
}

Two graphemes, even though there are three runes (Unicode code points).

You can see other examples in "How to manipulate strings in GO to reverse them?"

? alone is one grapheme, but, from unicode to code points converter, 4 runes:

• : women (1f469)
• dark skin (1f3fe)
• ZERO WIDTH JOINER (200d)
• red hair (1f9b0)

You should be able to do this in N operations, meaning in just one pass, O(n) time.

Use a map or int[] (if the problem is only for ints) to increment the counters, and also use a variable that keeps the key which has the max count seen. Everytime you increment a counter, ask what the value is and compare it to the key you used last, if the value is bigger update the key.

public class Mode {
public static int mode(final int[] n) {
    int maxKey = 0;
    int maxCounts = 0;

    int[] counts = new int[n.length];

    for (int i=0; i < n.length; i++) {
        counts[n[i]]++;
        if (maxCounts < counts[n[i]]) {
            maxCounts = counts[n[i]];
            maxKey = n[i];
        }
    }
    return maxKey;
}

public static void main(String[] args) {
    int[] n = new int[] { 3,7,4,1,3,8,9,3,7,1 };
    System.out.println(mode(n));
}
}

You're close. This should do the trick:

new {items = new [] {
    new {name = "command" , index = "X", optional = "0"}, 
    new {name = "command" , index = "X", optional = "0"}
}}

If your source was an enumerable of some sort, you might want to do this:

new {items = source.Select(item => new 
{
    name = item.Name, index = item.Index, options = item.Optional
})};

Set Primary Key then save Table and Refresh then go to Model.edmx delete Table and get again .

1. Decide how long the number will be.
2. take a delta 0.000000000000.......000001
3. see if the (sqrt(x))^2 - x is greater / equal /smaller than delta and decide based on the delta error.

You can also do something like this...

<input @input="myHandler('foo', 'bar', ...arguments)">

Evan You himself recommended this technique in one post on Vue forum. In general some events may emit more than one argument. Also as documentation states internal variable $event is meant for passing original DOM event.

Unlike what the spring-boot states, to get my spring-boot jar to serve the content: I had to add specifically register my src/main/resources/static content through this config class:

@Configuration
public class StaticResourceConfiguration implements WebMvcConfigurer {

    private static final String[] CLASSPATH_RESOURCE_LOCATIONS = {
            "classpath:/META-INF/resources/", "classpath:/resources/",
            "classpath:/static/", "classpath:/public/" };

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**")
            .addResourceLocations(CLASSPATH_RESOURCE_LOCATIONS);
    }
}

always use with statement like ;WITH then you'll never get this error. The WITH command required a ; between it and any previous command, by always using ;WITH you'll never have to remember to do this.

see WITH common_table_expression (Transact-SQL), from the section Guidelines for Creating and Using Common Table Expressions:

When a CTE is used in a statement that is part of a batch, the statement before it must be followed by a semicolon.

The main intention is for keeping your application's database file(s) in.

And no this will not be accessable from the web by default.

Here is a robust function for using UTL_File.putline that includes the necessary error handling. It also handles headers, footers and a few other exceptional cases.

I prefer to this way:

   /**
     *
     * @param host
     * @return true means ping success,false means ping fail.
     * @throws IOException
     * @throws InterruptedException
     */
    private static boolean ping(String host) throws IOException, InterruptedException {
        boolean isWindows = System.getProperty("os.name").toLowerCase().contains("win");

        ProcessBuilder processBuilder = new ProcessBuilder("ping", isWindows? "-n" : "-c", "1", host);
        Process proc = processBuilder.start();
        return proc.waitFor(200, TimeUnit.MILLISECONDS);
    }

This way can limit the blocking time to the specific time,such as 200 ms.

It works well in MacOS?Android and Windows, but should used in JDK 1.8.

This idea comes from Mohammad Banisaeid,but I can't comment. (You must have 50 reputation to comment)

Now both these methods fail at times when the log file is empty (has no content), yet the file size is not zero (2 bytes).

Actually, I think you will find that the file is NOT empty. Rather I think that you will find that those two characters are a CR and a NL; i.e. the file consists of one line that is empty.

If you want to test if a file is either empty or has a single empty line then a simple, relatively efficient way is:

try (BufferedReader br = new BufferedReader(FileReader(fileName))) {
    String line = br.readLine();
    if (line == null || 
        (line.length() == 0 && br.readLine() == null)) {
        System.out.println("NO ERRORS!");
    } else {
        System.out.println("SOME ERRORS!");
    }
}

Can we do this more efficiently? Possibly. It depends on how often you have to deal with the three different cases:

• a completely empty file
• a file consisting of a single empty line
• a file with a non-empty line, or multiple lines.

You can probably do better by using Files.length() and / or reading just the first two bytes. However, the problems include:

• If you both test the file size AND read the first few bytes then you are making 2 syscalls.
• The actual line termination sequence could be CR, NL or CR NL, depending on the platform. (I know you say this is for Windows, but what happens if you need to port your application? Or if someone sends you a non-Windows file?)
• It would be nice to avoid setting up stream / reader stack, but the file's character encoding could map CR and NL to something other than the bytes 0x0d and 0x0a. (For example ... UTF-16)
• Then there's the annoying habit of some Windows utilities have putting BOM markers into UTF-8 encoded files. (This would even mess up the simple version above!)

All of this means that the most efficient possible solution is going to be rather complicated.

What worked for me in Windows 7 is to remove the Host-only Network (in Oracle virtual box Preferences menu [CTRL+G] -> Network -> Host-only Networks). Genymotion will recreate it automatically at the next virtual device start. For the record; I'm using a Nexus S 2.3.7 virtual device.

In MySQL, It should be like this

INSERT INTO this_table_archive (col1, col2, ..., coln)
SELECT col1, col2, ..., coln
FROM this_table
WHERE entry_date < '2011-01-01 00:00:00';

You need to use objcopy to separate the debug information:

objcopy --only-keep-debug "${tostripfile}" "${debugdir}/${debugfile}"
strip --strip-debug --strip-unneeded "${tostripfile}"
objcopy --add-gnu-debuglink="${debugdir}/${debugfile}" "${tostripfile}"

I use the bash script below to separate the debug information into files with a .debug extension in a .debug directory. This way I can tar the libraries and executables in one tar file and the .debug directories in another. If I want to add the debug info later on I simply extract the debug tar file and voila I have symbolic debug information.

This is the bash script:

#!/bin/bash

scriptdir=`dirname ${0}`
scriptdir=`(cd ${scriptdir}; pwd)`
scriptname=`basename ${0}`

set -e

function errorexit()
{
  errorcode=${1}
  shift
  echo $@
  exit ${errorcode}
}

function usage()
{
  echo "USAGE ${scriptname} <tostrip>"
}

tostripdir=`dirname "$1"`
tostripfile=`basename "$1"`


if [ -z ${tostripfile} ] ; then
  usage
  errorexit 0 "tostrip must be specified"
fi

cd "${tostripdir}"

debugdir=.debug
debugfile="${tostripfile}.debug"

if [ ! -d "${debugdir}" ] ; then
  echo "creating dir ${tostripdir}/${debugdir}"
  mkdir -p "${debugdir}"
fi
echo "stripping ${tostripfile}, putting debug info into ${debugfile}"
objcopy --only-keep-debug "${tostripfile}" "${debugdir}/${debugfile}"
strip --strip-debug --strip-unneeded "${tostripfile}"
objcopy --add-gnu-debuglink="${debugdir}/${debugfile}" "${tostripfile}"
chmod -x "${debugdir}/${debugfile}"

Actually it depends on what kind of uses. If you want to use it in a test-framework I highly recommend selenium-python. It is a great tool for testing automation related to web-browsers.

from selenium import webdriver

driver = webdriver.Firefox()
driver.get("http://www.python.org")
