For anyone struggling with similar cases

No index signature with a parameter of type 'string' was found on type X

trying to use it with simple objects (used as dicts) like:

DNATranscriber = {
   G:"C",
   C: "G",
   T: "A",
   A: "U"
}

and trying to dynamically access the value from a calculated key like:

const key = getFirstType(dnaChain);
const result = DNATranscriber[key];

and you faced the error as shown above, you can use the keyof operator and try something like

const key = getFirstType(dnaChain) as keyof typeof DNATranscriber;

certainly you will need a guard at the result but if it seems more intuitive than some custom types magic, it is ok.

Without Error Handeling

//Load background texture
 new THREE.TextureLoader();
loader.load('https://images.pexels.com/photos/1205301/pexels-photo-1205301.jpeg' , function(texture)
            {
             scene.background = texture;  
            });

With Error Handling

// Function called when download progresses
var onProgress = function (xhr) {
  console.log((xhr.loaded / xhr.total * 100) + '% loaded');
};

// Function called when download errors
var onError = function (error) {
  console.log('An error happened'+error);
};

//Function  called when load completes.
var onLoad = function (texture) {
  var objGeometry = new THREE.BoxGeometry(30, 30, 30);
  var objMaterial = new THREE.MeshPhongMaterial({
    map: texture,
    shading: THREE.FlatShading
  });

  var boxMesh = new THREE.Mesh(objGeometry, objMaterial);
  scene.add(boxMesh);

  var render = function () {
    requestAnimationFrame(render);
    boxMesh.rotation.x += 0.010;
    boxMesh.rotation.y += 0.010;
      sphereMesh.rotation.y += 0.1;
    renderer.render(scene, camera);
  };

  render();
}


//LOAD TEXTURE and on completion apply it on box
var loader = new THREE.TextureLoader();
    loader.load('https://upload.wikimedia.org/wikipedia/commons/thumb/9/97/The_Earth_seen_from_Apollo_17.jpg/1920px-The_Earth_seen_from_Apollo_17.jpg', 
                onLoad, 
                onProgress, 
                onError);

In case You are using the VSC's screen terminal, The error might be due to the fact that you already runserver in some other shell.

Just click on the dropbox on the left of the + sign in the header of the terminal of VSC and select some other shell and check if the server is already running there. Quit that server and you are ready to launch a another server.

This should do it:

cat ~/Desktop/myfile.txt | sed s/:/\\n/g

Before installing the missing dependency, you need to check which version of PHP is installed on your system.

You can now proceed to installing the missing dependency by running:

If you have your data in a text-file, you can use LOAD DATA INFILE.

When loading a table from a text file, use LOAD DATA INFILE. This is usually 20 times faster than using INSERT statements.

Optimizing INSERT Statements

You can find more tips on how to speed up your insert statements on the link above.

The following code works for me.

//escape the double quotes in json string
String payload="{\"jsonrpc\":\"2.0\",\"method\":\"changeDetail\",\"params\":[{\"id\":11376}],\"id\":2}";
String requestUrl="https://git.eclipse.org/r/gerrit/rpc/ChangeDetailService";
sendPostRequest(requestUrl, payload);

method implementation:

public static String sendPostRequest(String requestUrl, String payload) {
    try {
        URL url = new URL(requestUrl);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();

        connection.setDoInput(true);
        connection.setDoOutput(true);
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Accept", "application/json");
        connection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
        OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");
        writer.write(payload);
        writer.close();
        BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        StringBuffer jsonString = new StringBuffer();
        String line;
        while ((line = br.readLine()) != null) {
                jsonString.append(line);
        }
        br.close();
        connection.disconnect();
        return jsonString.toString();
    } catch (Exception e) {
            throw new RuntimeException(e.getMessage());
    }

}

If I understand correctly that you want to play the animation on A only once youu have to add

animation-iteration-count: 1

to the style for the a.

Try this code. This seems working in my case.

$this->db->where(array('id !='=> $id))

I had the same problem with a spring boot project. The solution was to downgrade the spring-boot-starter-parent dependency version from 2.0.0.RELEASE to 1.5.10.RELEASE(you can move to any stable version)

from:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.0.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

to

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.10.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

Can use Extension Code Runner to run code with play icon on top Right ans by shortcut key :Ctrl+Alt+N and to abort Ctrl+Alt+M. But by default it only shows output of program but for receiving input you need to follow some steps:

Ctrl+, and then settings menu opens and Extensions>Run Code Configuration scroll down its attributes and find Edit in settings.json click on it and add following code insite it :

{ "code-runner.runInTerminal": true }

That is because in Python 3, they have replaced the print statement with the print function.

The syntax is now more or less the same as before, but it requires parens:

From the "what's new in python 3" docs:

Old: print "The answer is", 2*2
New: print("The answer is", 2*2)

Old: print x,           # Trailing comma suppresses newline
New: print(x, end=" ")  # Appends a space instead of a newline

Old: print              # Prints a newline
New: print()            # You must call the function!

Old: print >>sys.stderr, "fatal error"
New: print("fatal error", file=sys.stderr)

Old: print (x, y)       # prints repr((x, y))
New: print((x, y))      # Not the same as print(x, y)!

SELECT COUNT(*)
  FROM INFORMATION_SCHEMA.COLUMNS
 WHERE table_catalog = 'database_name' -- the database
   AND table_name = 'table_name'

Permanent:

UPDATE
  MyTable
SET
  MyColumn = UPPER(MyColumn)

Temporary:

SELECT
  UPPER(MyColumn) AS MyColumn
FROM
  MyTable

Figured I would post the snippet right here instead:

Make sure you declare support for the UITextViewDelegate protocol.

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {

    if([text isEqualToString:@"\n"]) {
        [textView resignFirstResponder];
        return NO;
    }

    return YES;
}

Swift 4.0 update:

func textView(_ textView: UITextView, shouldChangeTextIn range: NSRange, replacementText text: String) -> Bool {
    if text == "\n" {
        textView.resignFirstResponder()
        return false
    }
    return true
}

I'm usually facing this problem when dealing with events from an input field, like key up. But remember that the event could stem from anywhere, e.g. from a keyup listener on document, where there is no associated value. So in order to correctly provide the information I'd provide an additional type:

interface KeyboardEventOnInputField extends KeyboardEvent {
  target: HTMLInputElement;
}
...

  onKeyUp(e: KeyboardEventOnInputField) {
    const inputValue = e.target.value;
    ...
  }

If the input to the function has a type of Event, you might need to tell typescript what it actually is:

  onKeyUp(e: Event) {
    const evt = e as KeyboardEventOnInputField;
    const inputValue = evt.target.value;
    this.inputValue.next(inputValue);
  }

This is for example required in Angular.

Here is a work around I found if you want to only shuffle a subset of the DataFrame:

shuffle_to_index = 20
df = pd.concat([df.iloc[np.random.permutation(range(shuffle_to_index))], df.iloc[shuffle_to_index:]])

Shorthand for accepted answer

function str_lreplace($search, $replace, $subject){ 
    return is_numeric($pos=strrpos($subject,$search))?
    substr_replace($subject,$replace,$pos,strlen($search)):$subject;
}

If you instead have a jQuery object you want to render instead of the existing content: Then just reset the content and append the new.

var itemtoReplaceContentOf = $('#regTitle');
itemtoReplaceContentOf.html('');
newcontent.appendTo(itemtoReplaceContentOf);

Or:

$('#regTitle').empty().append(newcontent);

See for the protocols HTTPS and HTTP

Sometimes if you are using mixed protocols [this happens mostly with JSONP callbacks ] you can end up in this ERROR.

Make sure both the web-page and the resource page have the same HTTP protocols.

I was facing a similar problem. The solution that I found out was :

1. Declare an interface in your DialogFragment just like James McCracken has explained above.

2. Implement the interface in your activity (not fragment! That is not a good practice).

3. From the callback method in your activity, call a required public function in your fragment which does the job that you want to do.

Thus, it becomes a two-step process : DialogFragment -> Activity and then Activity -> Fragment

You need convert list to numpy array and then reshape:

df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)
   a  b  c
0  1  2  3
1  4  5  6
2  7  8  9

This isn't a single JSON object. You have an array of JSON objects. You need to loop over array first and then access each object. Maybe the following kickoff example is helpful:

var arrayOfObjects = [{
  "id": 28,
  "Title": "Sweden"
}, {
  "id": 56,
  "Title": "USA"
}, {
  "id": 89,
  "Title": "England"
}];

for (var i = 0; i < arrayOfObjects.length; i++) {
  var object = arrayOfObjects[i];
  for (var property in object) {
    alert('item ' + i + ': ' + property + '=' + object[property]);
  }
  // If property names are known beforehand, you can also just do e.g.
  // alert(object.id + ',' + object.Title);
}

If the array of JSON objects is actually passed in as a plain vanilla string, then you would indeed need eval() here.

var string = '[{"id":28,"Title":"Sweden"}, {"id":56,"Title":"USA"}, {"id":89,"Title":"England"}]';
var arrayOfObjects = eval(string);
// ...

To learn more about JSON, check MDN web docs: Working with JSON .

Yes, quite straight forward:

Private _name As String

Public Property Name() As String
    Get
        Return _name
    End Get
    Private Set(ByVal value As String)
        _name = value
    End Set
End Property

use this code 100% fix your problem

enter this code in firstFragment

public static yourNameParentFragment newInstance() {

    Bundle args = new Bundle();
    args.putBoolean("yourKey",yourValue);
    YourFragment fragment = new YourFragment();
    fragment.setArguments(args);
    return fragment;
}

this sample send boolean data

and in SecendFragment

yourNameParentFragment name =yourNameParentFragment.newInstance();
   Bundle bundle;
   bundle=sellDiamondFragments2.getArguments();
  boolean a= bundle.getBoolean("yourKey");

must value in first fragment is static

happy code

You can pass any number of arguments to the function that apply is calling through either unnamed arguments, passed as a tuple to the args parameter, or through other keyword arguments internally captured as a dictionary by the kwds parameter.

For instance, let's build a function that returns True for values between 3 and 6, and False otherwise.

s = pd.Series(np.random.randint(0,10, 10))
s

0    5
1    3
2    1
3    1
4    6
5    0
6    3
7    4
8    9
9    6
dtype: int64

s.apply(lambda x: x >= 3 and x <= 6)

0     True
1     True
2    False
3    False
4     True
5    False
6     True
7     True
8    False
9     True
dtype: bool

This anonymous function isn't very flexible. Let's create a normal function with two arguments to control the min and max values we want in our Series.

def between(x, low, high):
    return x >= low and x =< high

We can replicate the output of the first function by passing unnamed arguments to args:

s.apply(between, args=(3,6))

Or we can use the named arguments

s.apply(between, low=3, high=6)

Or even a combination of both

s.apply(between, args=(3,), high=6)

I recommend you to use an unordered list for your image gallery.

You should use my code unless you want the image to gain instantly 50% opacity after you hover out. You will have a smoother transition.

#photos li {
    opacity: .5;
    transition: opacity .5s ease-out;
    -moz-transition: opacity .5s ease-out;
    -webkit-transition: opacity .5s ease-out;
    -o-transition: opacity .5s ease-out;
}

#photos li:hover {
    opacity: 1;
}

This is how you get rid of that notice and be able to open those grid cells for edit

1) click "STRUCTURE"

2) go to the field you want to be a primary key (and this usually is the 1st one ) and then click on the "PRIMARY" and "INDEX" fields for that field and accept the PHPMyadmin's pop-up question "OK".

3) pad yourself in the back.

ok figured it out:

<string name="sample_string"><![CDATA[some test line 1 <br />some test line 2]]></string>

so wrap in CDATA is necessary and breaks added inside as html tags

Well, you may try this '.*[0-9]'

IIF is not a standard SQL construct, but if it's supported by your database, you can achieve a more elegant statement producing the same result:

SELECT JobId, JobName,

COUNT(IIF (Priority=1, 1, NULL)) AS Priority1,
COUNT(IIF (Priority=2, 1, NULL)) AS Priority2,
COUNT(IIF (Priority=3, 1, NULL)) AS Priority3,
COUNT(IIF (Priority=4, 1, NULL)) AS Priority4,
COUNT(IIF (Priority=5, 1, NULL)) AS Priority5

FROM TableName
GROUP BY JobId, JobName

Tuples are immutable; you can't change which variables they contain after construction. However, you can concatenate or slice them to form new tuples:

a = (1, 2, 3)
b = a + (4, 5, 6)  # (1, 2, 3, 4, 5, 6)
c = b[1:]  # (2, 3, 4, 5, 6)

And, of course, build them from existing values:

name = "Joe"
age = 40
location = "New York"
joe = (name, age, location)

how will I know that some tables are locked?

You can use SHOW OPEN TABLES command to view locked tables.

how do I unlock tables manually?

If you know the session ID that locked tables - 'SELECT CONNECTION_ID()', then you can run KILL command to terminate session and unlock tables.

Probably my solution will suit for a lot of users, I hope so.

What I am suggesting it is making TextView with your style. It works for me perfectly, and has got all features, like a button.

First of all lets make button style, which you can use everywhere...I am creating button_with_hover.xml

    <?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" >
        <shape android:shape="rectangle"  >
            <corners android:radius="3dip" />
            <stroke android:width="1dip" android:color="#8dbab3" />
            <gradient android:angle="-90" android:startColor="#48608F" android:endColor="#48608F"  />
        </shape>

        <!--#284682;-->
        <!--border-color: #223b6f;-->
    </item>
    <item android:state_focused="true">
        <shape android:shape="rectangle"  >
            <corners android:radius="3dip" />
            <stroke android:width="1dip" android:color="#284682" />
            <solid android:color="#284682"/>
        </shape>
    </item>
    <item >
        <shape android:shape="rectangle"  >
            <corners android:radius="3dip" />
            <stroke android:width="1dip" android:color="@color/ControlColors" />
            <gradient android:angle="-90" android:startColor="@color/ControlColors" android:endColor="@color/ControlColors" />
        </shape>
    </item>

</selector>

Secondly, Lets create a textview button.

    <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginBottom="20dip"
    android:layout_gravity="right|bottom"
    android:gravity="center"
    android:padding="12dip"
    android:background="@drawable/button_with_hover"
    android:clickable="true"
    android:drawableLeft="@android:drawable/btn_star_big_off"
    android:textColor="#ffffffff"
    android:text="Golden Gate" />

And this is a result. Then style your custom button with any colors or any other properties and margins. Good luck

.remove() is deprecated. instead we can use deleteMany

DateTime.deleteMany({}, callback).

So one does not have to find and replace the Object.keys method, another approach would be this code early in the execution of the script:

if(!Object.keys)
{
  Object.keys = function(obj)
  {
    return $.map(obj, function(v, k)
    {
      return k;
    });
  };
 }

Rather than using Ctrl + K, X you can also just type prop and then hit Tab twice.

Simple Invalidate/Restart fixed it for me. No other actions were taken

<input id="typeahead-input" type="text" data-provide="typeahead" />

<script type="text/javascript">

I use command:

openssl x509 -inform PEM -in certificate.cer -out certificate.crt

But CER is an X.509 certificate in binary form, DER encoded. CRT is a binary X.509 certificate, encapsulated in text (base-64) encoding.

Because of that, you maybe should use:

openssl x509 -inform DER -in certificate.cer -out certificate.crt

And then to import your certificate:

Copy your CA to dir:

/usr/local/share/ca-certificates/

Use command:

sudo cp foo.crt /usr/local/share/ca-certificates/foo.crt

Update the CA store:

sudo update-ca-certificates

I don't have enough reputation to comment, so I'll leave my version of Salil Dwahan's version here. Works for Swift 5, XCode 11.3.

First place your button on IB, select type "Custom" and create an outlet and an action with the Assistant Layout (Ctrl + Drag). Include the following code and it should end like this:

class YourViewController: UIViewController {
    @IBOutlet weak var checkbox: UIButton!
    @IBAction func checkboxTapped(_ sender: UIButton) {
        checkbox.isSelected = !checkbox.isSelected
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        checkbox.setImage(UIImage.init(named: "checkMark"), for: .selected)
    }
}

Don't forget to add the image to Assets and change the name to match!

checkbox.isSelected is the way to check

For Laravel 5.2 (previous versions I did not use)

Paste the code into the file app\Http\Controllers\Auth\AurhController.php

   /**
 * Overrides method in class 'AuthenticatesUsers'
 *
 * @return \Illuminate\Contracts\View\Factory|\Illuminate\View\View
 */
public function showLoginForm()
{
    $view = property_exists($this, 'loginView')
        ? $this->loginView : 'auth.authenticate';
    if (view()->exists($view)) {
        return view($view);
    }
    /**
     * seve the previous page in the session
     */
    $previous_url = Session::get('_previous.url');
    $ref = isset($_SERVER['HTTP_REFERER']) ? $_SERVER['HTTP_REFERER'] : '';
    $ref = rtrim($ref, '/');
    if ($previous_url != url('login')) {
        Session::put('referrer', $ref);
        if ($previous_url == $ref) {
            Session::put('url.intended', $ref);
        }
    }
    /**
     * seve the previous page in the session
     * end
     */
    return view('auth.login');
}
/**
 * Overrides method in class 'AuthenticatesUsers'
 *
 * @param Request $request
 * @param $throttles
 *
 * @return \Illuminate\Http\RedirectResponse
 */
protected function handleUserWasAuthenticated(Request $request, $throttles)
{
    if ($throttles) {
        $this->clearLoginAttempts($request);
    }
    if (method_exists($this, 'authenticated')) {
        return $this->authenticated($request, Auth::guard($this->getGuard())->user());
    }
    /*return to the previous page*/
    return redirect()->intended(Session::pull('referrer'));
    /*return redirect()->intended($this->redirectPath()); /*Larevel default*/
}

And import namespace: use Session;

If you have not made any changes to the file app\Http\Controllers\Auth\AurhController.php, you can just replace it with the file from the GitHub

The fragment identifier (also known as: Fragment IDs, Anchor Identifiers, Named Anchors) introduced by a hash mark # is the optional last part of a URL for a document. It is typically used to identify a portion of that document.

<a href="http://www.someuri.com/page#fragment">Link to fragment identifier</a>

Syntax for URIs also allows an optional query part introduced by a question mark ?. In URIs with a query and a fragment the fragment follows the query.

<a href="http://www.someuri.com/page?query=1#fragment">Link to fragment with a query</a>

When a Web browser requests a resource from a Web server, the agent sends the URI to the server, but does not send the fragment. Instead, the agent waits for the server to send the resource, and then the agent (Web browser) processes the resource according to the document type and fragment value.

Named Anchors <a name="fragment"> are deprecated in XHTML 1.0, the ID attribute is the suggested replacement. <div id="fragment"></div>

it clears stdin buffer before reading. From the man page:

For output streams, fflush() forces a write of all user-space buffered data for the given output or update stream via the stream's underlying write function. For input streams, fflush() discards any buffered data that has been fetched from the underlying file, but has not been consumed by the application.

Note: This is Linux-specific, using fflush() on input streams is undefined by the standard, however, most implementations behave the same as in Linux.

You are going to need to call the SmsManager class. You are probably going to need to use the STATUS_ON_ICC_READ constant and maybe put what you get there into your apps local db so that you can keep track of what you have already read vs the new stuff for your app to parse through. BUT bear in mind that you have to declare the use of the class in your manifest, so users will see that you have access to their SMS called out in the permissions dialogue they get when they install. Seeing SMS access is unusual and could put some users off. Good luck.

Here is the link that goes into depth on the Sms Manager

    curl_multi_add_handle($cmi, $curl);

    $running = null;
    do {
        curl_multi_exec($cmi, $running);
        sleep(.1);
        if(!$waitResult)
        break;
    } while ($running > 0);

The significant differences between the two methods are the class of the objects they return when used for extraction and whether they may accept a range of values, or just a single value during assignment.

Consider the case of data extraction on the following list:

foo <- list( str='R', vec=c(1,2,3), bool=TRUE )

Say we would like to extract the value stored by bool from foo and use it inside an if() statement. This will illustrate the differences between the return values of [] and [[]] when they are used for data extraction. The [] method returns objects of class list (or data.frame if foo was a data.frame) while the [[]] method returns objects whose class is determined by the type of their values.

So, using the [] method results in the following:

if( foo[ 'bool' ] ){ print("Hi!") }
Error in if (foo["bool"]) { : argument is not interpretable as logical

class( foo[ 'bool' ] )
[1] "list"

This is because the [] method returned a list and a list is not valid object to pass directly into an if() statement. In this case we need to use [[]] because it will return the "bare" object stored in 'bool' which will have the appropriate class:

if( foo[[ 'bool' ]] ){ print("Hi!") }
[1] "Hi!"

class( foo[[ 'bool' ]] )
[1] "logical"

The second difference is that the [] operator may be used to access a range of slots in a list or columns in a data frame while the [[]] operator is limited to accessing a single slot or column. Consider the case of value assignment using a second list, bar():

bar <- list( mat=matrix(0,nrow=2,ncol=2), rand=rnorm(1) )

Say we want to overwrite the last two slots of foo with the data contained in bar. If we try to use the [[]] operator, this is what happens:

foo[[ 2:3 ]] <- bar
Error in foo[[2:3]] <- bar : 
more elements supplied than there are to replace

This is because [[]] is limited to accessing a single element. We need to use []:

foo[ 2:3 ] <- bar
print( foo )

$str
[1] "R"

$vec
     [,1] [,2]
[1,]    0    0
[2,]    0    0

$bool
[1] -0.6291121

Note that while the assignment was successful, the slots in foo kept their original names.

The following POSIX program will print the names of the files in the current directory:

#define _XOPEN_SOURCE 700
#include <stdio.h>
#include <sys/types.h>
#include <dirent.h>

int main (void)
{
  DIR *dp;
  struct dirent *ep;     
  dp = opendir ("./");

  if (dp != NULL)
  {
    while (ep = readdir (dp))
      puts (ep->d_name);

    (void) closedir (dp);
  }
  else
    perror ("Couldn't open the directory");

  return 0;
}

I saw a question the other day where someone inadvertently used an incomplete type by specifying something like

struct a {
    int q; 
}; 
struct A *x; 
x->q = 3;

The compiler knew that struct A was a struct, despite A being totally undefined, by virtue of the struct keyword.

That was in C++, where such usage of struct is atypical (and, it turns out, can lead to foot-shooting). In C if you do

typedef struct a {
    ...
} a;

then you can use a as the typename and omit the struct later. This will lead the compiler to give you an undefined identifier error later, rather than incomplete type, if you mistype the name or forget a header.

Heres an easy way to do find the keys of a given value:

    clients = {
      "yellow"=>{"client_id"=>"2178"}, 
      "orange"=>{"client_id"=>"2180"}, 
      "red"=>{"client_id"=>"2179"}, 
      "blue"=>{"client_id"=>"2181"}
    }

    p clients.rassoc("client_id"=>"2180")

...and to find the value of a given key:

    p clients.assoc("orange") 

it will give you the key-value pair.

I have implemented Alert Dialog for exception throwing on to the current activitty view.Whenever I had given like this

AlertDialog.Builder builder = new AlertDialog.Builder(context);

Given same Window Exception.I write code for alert out of onCreate().So simple I used context = this; after setContentView() statement in onCreate() method.Taken context variable as global like Context context;

Code sample is

static Context context;

 public void onCreate(Bundle savedInstanceState)  { 
        super.onCreate(savedInstanceState); 


        setContentView(R.layout.network); 
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

        context = this;
.......

Alert Method Sample is

private void alertException(String execMsg){
        Log.i(TAG,"in alertException()..."+context);
        Log.e(TAG,"Exception :"+execMsg);
        AlertDialog.Builder builder = new AlertDialog.Builder(context);
.......

It works fine for me.Actually I searched for this error on StackOverflow I found this query.After reading all responses of this post, I tried this way so It works .I thought this is a simple solution for overcome the exception.

Thanks, Rajendar

Honestly I followed these examples to a tee and they simply didn't work. What I ended up doing after struggling pointlessly trying to get Excel to work was to just copy the entire contents of my column to NotePad++ where I was able to find an easy solution within minutes. Take a look at this: Removing duplicate rows in Notepad++

Edit: Here is a brief overview of how to do it in TextFX:

Plugins -> Plugin Manager -> Show Plugin Manager -> Available tab -> TextFX -> Install

After TextFX is installed in NotePad++, then you select all your text you want to remove duplicates from, then make sure to check: TextFX -> TextFX Tools -> Sort outputs only UNIQUE lines

Then click "sort lines case sensitive" or "sort lines case insensitive" and it will perform the unique sort.

To output an object to the console, you have to stringify the object first:

success:function(data){
     console.log(JSON.stringify(data));
}

There is 3 rapid examples with pure CSS and without javascript where the content appears "on click", with a "maintained click" and a third "onhover" (all only tested in Chrome). Sorry for the up of this post but this question are the first seo result and maybe my contribution can help beginner like me

I think (not tested) but the advantage of argument "content" that you can add great icon like from Font Awesome (its \f-Code) or an hexadecimal icon in place of the text "Hide" and "Show" to internationalize the trick.

You can use git rebase -i (against the branch you branched from) 'i' for interactive.

Replace the pick next to the commit comment you wish to change with r (or reword), save and exit and upon doing so you'll be able to make the edit.

git push once again and you're done!

The thing is that you are using the option -t when running your container.

Could you check if enabling the tty option (see reference) in your docker-compose.yml file the container keeps running?

Some CSS :

table td, table td * {
    vertical-align: top;
}

In the listing provided by PenguinTD, I do not understand why the ranges are reversed, it works without having to reverse the ranges. Linear range conversion is based upon the linear equation Y=Xm+n, where m and n are derived from the given ranges. Rather than refer to the ranges as min and max, it would be better to refer to them as 1 and 2. So the formula would be:

Y = (((X - x1) * (y2 - y1)) / (x2 - x1)) + y1

Where Y=y1 when X=x1, and Y=y2 when X=x2. x1, x2, y1 & y2 can be given any positive or negative value. Defining the expression in a macro makes it more useful,it can then be used with any argument names.

#define RangeConv(X, x1, x2, y1, y2) (((float)((X - x1) * (y2 - y1)) / (x2 - x1)) + y1)

The float cast would ensure floating point division in the case where all the arguments are integer values. Depending on the application it may not be necessary to check the ranges x1=x2 and y1==y2.

Yes, you can do this in three steps:

1. Place the files you want to protect in a subdirectory of the directory where your code is running.

   www.foo.com/player.html
   www.foo.com/videos/video.mp4
   

2. Save a file in that subdirectory named ".htaccess" and add the lines below.

   www.foo.com/videos/.htaccess

   #Contents of .htaccess
   
   RewriteEngine on
   RewriteCond %{HTTP_REFERER} !^http://foo.com/.*$ [NC]
   RewriteCond %{HTTP_REFERER} !^http://www.foo.com/.*$ [NC]
   RewriteRule .(mp4|mp3|avi)$ - [F]
   

Now the source link is useless, but we still need to make sure any user attempting to download the file cannot be directly served the file.

3. For a more complete solution, now serve the video with a flash player (or html canvas) and never link to the video directly. To just remove the right click menu, add to your HTML:

   <body oncontextmenu="return false;">
   

The Result:

www.foo.com/player.html will correctly play video, but if you visit www.foo.com/videos/video.mp4:

Error Code 403: FORBIDDEN

This will work for direct download, cURL, hotlinking, you name it.

This is a complete answer to the two questions asked and not an answer to the question: "can I stop a user from downloading a video they have already downloaded."

struct TestStruct {
        int id;
        TestStruct() : id(42)
        {
        }
};

Unless I'm misunderstanding, you lost your .ssh directory containing your private key on your local machine and so you want to remove the public key which was on a server and which allowed key-based login.

In that case, it will be stored in the .ssh/authorized_keys file in your home directory on the server. You can just edit this file with a text editor and delete the relevant line if you can identify it (even easier if it's the only entry!).

I hope that key wasn't your only method of access to the server and you have some other way of logging in and editing the file. You can either manually add a new public key to authorised_keys file or use ssh-copy-id. Either way, you'll need password authentication set up for your account on the server, or some other identity or access method to get to the authorized_keys file on the server.

ssh-add adds identities to your SSH agent which handles management of your identities locally and "the connection to the agent is forwarded over SSH remote logins, and the user can thus use the privileges given by the identities anywhere in the network in a secure way." (man page), so I don't think it's what you want in this case. It doesn't have any way to get your public key onto a server without you having access to said server via an SSH login as far as I know.

Make sure that the database is created. I got the same error when I applied the migration to the wrong project in the solution. When I applied the migration to the right project, it created the database and that solved the error.

First rollback your previous migration

php artisan migrate:rollback

After that, you can modify your existing migration file (add new , rename or delete columns) then Re-Run your migration file

php artisan migrate

You can try following sample http://jsfiddle.net/xKJB8/3/

Does WHERE-clause can be actually used with INSERT-INTO-VALUES in any case?

The answer is definitively no.

Adding a WHERE clause after INSERT INTO ... VALUES ... is just invalid SQL, and will not parse.

The error returned by MySQL is:

mysql> INSERT INTO Users( weight, desiredWeight ) VALUES ( 160, 145 ) WHERE id = 1;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE id = 1' at line 1

The most important part of the error message is

... syntax to use near 'WHERE id = 1' ...

which shows the specific part the parser did not expect to find here: the WHERE clause.

You can use the following code to both work with the command line and a web browser. Put this code above your PHP code. It creates a $_GET variable for each command line parameter.

In your code you only need to check for $_GET variables then, not worrying about if the script is called from the web browser or command line.

if(isset($argv))
    foreach ($argv as $arg) {
        $e=explode("=",$arg);
        if(count($e)==2)
            $_GET[$e[0]]=$e[1];
        else
            $_GET[$e[0]]=0;
    }

The flexbox approach!

In supported browsers, you can use the following:

Example Here

.parent {
  display: flex;
  flex-direction: column;
}
.child {
  margin-top: auto;
}

.parent {_x000D_
  height: 100px;_x000D_
  border: 5px solid #000;_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
}_x000D_
.child {_x000D_
  height: 40px;_x000D_
  width: 100%;_x000D_
  background: #f00;_x000D_
  margin-top: auto;_x000D_
}

<div class="parent">_x000D_
  <div class="child">Align to the bottom</div>_x000D_
</div>

The solution above is probably more flexible, however, here is an alternative solution:

Example Here

.parent {
  display: flex;
}
.child {
  align-self: flex-end;
}

.parent {_x000D_
  height: 100px;_x000D_
  border: 5px solid #000;_x000D_
  display: flex;_x000D_
}_x000D_
.child {_x000D_
  height: 40px;_x000D_
  width: 100%;_x000D_
  background: #f00;_x000D_
  align-self: flex-end;_x000D_
}

<div class="parent">_x000D_
  <div class="child">Align to the bottom</div>_x000D_
</div>

As a side note, you may want to add vendor prefixes for additional support.

.*

. is any char, * means repeated zero or more times.

This is what I did for bulk update:

UPDATE tableName SET isDeleted = 1 where columnName in ('430903GW4j683537882','430903GW4j667075431','430903GW4j658444015')

To create an environment named py37 with python 3.7, using the channel conda-forge and a list of packages:

conda create -y --name py37 python=3.7
conda install --force-reinstall -y -q --name py37 -c conda-forge --file requirements.txt
conda activate py37
...
conda deactivate

Flags explained:

• -y: Do not ask for confirmation.
• --force-reinstall: Install the package even if it already exists.
• -q: Do not display progress bar.
• -c: Additional channel to search for packages. These are URLs searched in the order

The ansible-role dockpack.base_miniconda can manage conda environments and can be used to create a docker base image.

Alternatively you can create an environment.yml file instead of requirements.txt:

name: py37
channels:
  - conda-forge
dependencies:
  - python=3.7
  - numpy=1.9.*
  - pandas

Use this command to list the environments you have:

conda info --envs

Use this command to remove the environment:

conda env remove -n py37

As @Ninefingers mentioned, pthreads are unix-only. Posix only, really.

That said, Microsoft does have a library that duplicates pthreads:

Or mayby even more simple with convert from hablar:

library(hablar)

dat %>% 
  convert(fct(fac1, fac2, fac3),
          num(dbl1, dbl2, dbl3))

or combines with tidyselect:

dat %>% 
  convert(fct(contains("fac")),
          num(contains("dbl")))

Use the Soot Java Optimization framework to directly modify the bytecode. http://www.sable.mcgill.ca/soot/

Soot is completely written in Java and works with new Java versions.

After observing number of viewers to this question I decided to conclude an answer from Vikramaditya and Sandeep.

To build the production code the first thing you have to create is production configuration with optimization packages like,

  new webpack.optimize.CommonsChunkPlugin('common.js'),
  new webpack.optimize.DedupePlugin(),
  new webpack.optimize.UglifyJsPlugin(),
  new webpack.optimize.AggressiveMergingPlugin()

Then in the package.json file you can configure the build procedure with this production configuration

"scripts": {
    "build": "NODE_ENV=production webpack --config ./webpack.production.config.js"
},

now you have to run the following command to initiate the build

npm run build

As per my production build configuration webpack will build the source to ./dist directory.

Now your UI code will be available in ./dist/ directory. Configure your server to serve these files as static assets. Done!

In bash version 4 associative arrays were introduced.

declare -A arr

arr["key1"]=val1

arr+=( ["key2"]=val2 ["key3"]=val3 )

The arr array now contains the three key value pairs. Bash is fairly limited what you can do with them though, no sorting or popping etc.

for key in ${!arr[@]}; do
    echo ${key} ${arr[${key}]}
done

Will loop over all key values and echo them out.

Note: Bash 4 does not come with Mac OS X because of its GPLv3 license; you have to download and install it. For more on that see here

Please check your project/module language levels (Project Structure | Project; Project Structure | Modules | module-name | Sources). You might also want to take a look at Settings | Compiler | Java Compiler | Per-module bytecode version.

Set also this:

File -> Project Structure -> Modules :: Sources (next to Paths and Dependencies) and that has a "Language level" option which also needs to be set correctly.

For multiple lines

xposition = [0.3, 0.4, 0.45]

I may be simplifying the issue, but does td {border-right: 1px solid red;} work for your table setup?

@echo off

for /F "tokens=1,2,3*" %%a in ( 'echo(!array!' ) do (

 echo(vehicle[!index!]=%%a color[!index!]=%%b 
 set vehicle[!index!]=%%a
 set color[!index!]=%%b
 set /a index=!index!+1   

)

echo use the arrays

To get information about the current store from anywhere in Magento, use:

<?php
$store = Mage::app()->getStore();

This will give you a Mage_Core_Model_Store object, which has some of the information you need:

<?php
$name = $store->getName();

As for your other question about line number, I'm not sure what you mean. If you mean that you want to know what line number in the code you are on (for error handling, for instance), try:

<?php
$line      = __LINE__;
$file      = __FILE__;
$class     = __CLASS__;
$method    = __METHOD__;
$namespace = __NAMESPACE__;

As an alternative to rewriting history, consider using git replace as in this article from the Pro Git book. The example discussed involves replacing a parent commit to simulate the beginning of a tree, while still keeping the full history as a separate branch for safekeeping.

Its quite old question, and I'm not sure if it was an option at that time, but this is the reason why I always prefer DependencyInjection by the constructor than by the value.

I can imagine that your class might look like this:

class ExampleClass{

   @Autowired
   private Dog dog;

   @Value("${this.property.value}") 
   private String thisProperty;

   ...other stuff...
}

You can change it to:

class ExampleClass{

   private Dog dog;
   private String thisProperty;

   //optionally @Autowire
   public ExampleClass(final Dog dog, @Value("${this.property.value}") final String thisProperty){
      this.dog = dog;
      this.thisProperty = thisProperty;
   }

   ...other stuff...
}

With this implementation, the spring will know what to inject automatically, but for unit testing, you can do whatever you need. For example Autowire every dependency wth spring, and inject them manually via constructor to create "ExampleClass" instance, or use only spring with test property file, or do not use spring at all and create all object yourself.

I had similar issue and just wanted to post an answer for others in my situation.

I have a solution running a ASP.NET Web Application with multiple other C# class lib projects.

My ASP.NET Web Application wasn't using json, but other projects where.

This is how I fixed it:

1. I made sure all projects where using latest version (6) using NuGet Update on all projects currently using any version of json - this didn't fix the issue
2. I added json to the web application using NuGet - this fixed the issue (let me dive into why):

Step 2 was first of all adding a configuration information for json, that suggest that all projects, use the latest version (6) no matter what version they have. Adding the assembly binding to Web.Config is most likely the fix.

However, step 2 also cleaned up som legacy code. It turned out we have previously used an old version (5) of json in our Web Application and the NuGet folders wasn't deleted when the reference was (I suspect: manually) removed. Adding the latest json (6), removed the old folders (json v5). This might be part of the fix as well.

The function could be called as if it was in the same JS File as long as the file containing the definition of the function has been loaded before the first use of the function.

I.e.

File1.js

function alertNumber(number) {
    alert(number);
}

File2.js

function alertOne() {
     alertNumber("one");
}

HTML

<head>
....
    <script src="File1.js" type="text/javascript"></script> 
    <script src="File2.js" type="text/javascript"></script> 
....
</head>
<body>
....
    <script type="text/javascript">
       alertOne();
    </script>
....
</body>

The other way won't work. As correctly pointed out by Stuart Wakefield. The other way will also work.

HTML

<head>
....
    <script src="File2.js" type="text/javascript"></script> 
    <script src="File1.js" type="text/javascript"></script> 
....
</head>
<body>
....
    <script type="text/javascript">
       alertOne();
    </script>
....
</body>

What will not work would be:

HTML

<head>
....
    <script src="File2.js" type="text/javascript"></script> 
    <script type="text/javascript">
       alertOne();
    </script>
    <script src="File1.js" type="text/javascript"></script> 
....
</head>
<body>
....
</body>

Although alertOne is defined when calling it, internally it uses a function that is still not defined (alertNumber).

I didn't verify this myself, but you can look at this JavaScript implementation of Java's String.hashCode() method. Seems reasonably short.

With this prototype you can simply call .hashCode() on any string, e.g. "some string".hashCode(), and receive a numerical hash code (more specifically, a Java equivalent) such as 1395333309.

String.prototype.hashCode = function() {
    var hash = 0;
    if (this.length == 0) {
        return hash;
    }
    for (var i = 0; i < this.length; i++) {
        var char = this.charCodeAt(i);
        hash = ((hash<<5)-hash)+char;
        hash = hash & hash; // Convert to 32bit integer
    }
    return hash;
}

just install any package you want with -g

npm install -g express

Say util.R produces a function foo(). You can check if this function is available in the global environment and source the script if it isn't:

if(identical(length(ls(pattern = "^foo$")), 0))
    source("util.R")

That will find anything with the name foo. If you want to find a function, then (as mentioned by @Andrie) exists() is helpful but needs to be told exactly what type of object to look for, e.g.

if(exists("foo", mode = "function"))
    source("util.R")

Here is exists() in action:

> exists("foo", mode = "function")
[1] FALSE
> foo <- function(x) x
> exists("foo", mode = "function")
[1] TRUE
> rm(foo)
> foo <- 1:10
> exists("foo", mode = "function")
[1] FALSE

Hello Everyone in Android programming... I have same issue Android emulator gets killed but get rid of this issue successfully and android emulator run properly by doing following things...

1. Firstly, I updated my SDKs from android studio SDK manager but issue does not resolved.
2. Secondly, I have faced problems regarding my computer C Drive space where path of SDK folder is located. My C Drive space is running very low and does not allow me to update SDK from android studio showing me error and my Android emulator gets killed then I moved my SDK folder from C Drive to another drive D which have huge space available, then Changed my sdk folder path form android studio and restart it and matter resolved successfully. Cheers...
   Best Regards

Lucas on PHP.net provided a reliable way to check if a variable exists. In his example, he iterates through a copy of the global variable array (or a scoped array) of variables, changes the value to a randomly generated value, and checks for the generated value in the copied array.

function variable_name( &$var, $scope=false, $prefix='UNIQUE', $suffix='VARIABLE' ){
    if($scope) {
        $vals = $scope;
    } else {
        $vals = $GLOBALS;
    }
    $old = $var;
    $var = $new = $prefix.rand().$suffix;
    $vname = FALSE;
    foreach($vals as $key => $val) {
        if($val === $new) $vname = $key;
    }
    $var = $old;
    return $vname;
}

Then try:

$a = 'asdf';
$b = 'asdf';
$c = FALSE;
$d = FALSE;

echo variable_name($a); // a
echo variable_name($b); // b
echo variable_name($c); // c
echo variable_name($d); // d

Be sure to check his post on PHP.net: http://php.net/manual/en/language.variables.php

Because if you don't make a copy then the indices can still be manipulated elsewhere even if you assign the dataFrame to a different name.

For example:

df2 = df
func1(df2)
func2(df)

func1 can modify df by modifying df2, so to avoid that:

df2 = df.copy()
func1(df2)
func2(df)

You'll find that instances of list do not provide a __hash__ --rather, that attribute of each list is actually None (try print [].__hash__). Thus, list is unhashable.

The reason your code works with list and not set is because set constructs a single set of items without duplicates, whereas a list can contain arbitrary data.

     protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        int index = GridView1.SelectedIndex;
        int id = Convert.ToInt32(GridView1.DataKeys[index].Value);
        SqlConnection con = new SqlConnection(str);
        SqlCommand com = new SqlCommand("spDelete", con);
        com.Parameters.AddWithValue("@PatientId", id);
        con.Open();
        com.ExecuteNonQuery();

Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

A solution that does not ignore changes in directory properties

I tried to use the solution based on changelist, but I have a couple of issues with it. First my repository has thousand of files, so the changelist to be committed is huge, and my svn status output became way too long and needed to be parsed to be useful. Most important is that I wanted to commit changes that came from a merge, which means they include property changes. When committing a changelist, the svn properties attached to the directory are not committed, so I had to do an extra commit:

svn ci --cl work -m "this commits files from the work changelist only"
svn up
svn ci --depth empty DIR . -m "record merge properties"

You may have to do that for several directories (here I record the properties of DIR and of the current dir .), basically those with a M in the second column when issuing the svn status command.

Solution

I used patches and svn patch. In pseudo-code:

svn diff $IGNORE_FILES > MYPATCH   # get the mods to ignore
svn patch --reverse-diff MYPATCH   # remove the mods
svn ci -m "message"                # check-in files and directory properties
svn patch MYPATCH                  # re-apply the mods

Like other posters, I end up using a script to maintain the list of files to ignore:

#! /usr/bin/env bash

finish() {
    svn patch MYPATCH               # re-apply the mods
}
trap finish EXIT

IGNORE_FILES="\
sources/platform/ecmwf-cca-intel-mpi.xml \
runtime/classic/platform/ecmwf-cca.job.tmpl \
runtime/classic/platform/ecmwf-cca-intel.xml"

svn diff $IGNORE_FILES > MYPATCH # get the mods to ignore
svn patch --reverse-diff MYPATCH # remove the mods

svn "$@"

I typically used it with ci and revert -R ..

What is the difference?

From the documentation:

- (Boolean) instance_of?(class)

Returns true if obj is an instance of the given class.

and:

- (Boolean) is_a?(class)
- (Boolean) kind_of?(class)

Returns true if class is the class of obj, or if class is one of the superclasses of obj or modules included in obj.

If that is unclear, it would be nice to know what exactly is unclear, so that the documentation can be improved.

When should I use which?

Never. Use polymorphism instead.

Why are there so many of them?

I wouldn't call two "many". There are two of them, because they do two different things.

This isn't exactly what's asked, but here's an important note: When running Java on a Windows machine, the Oracle installer puts a "java.exe" into C:\Windows\system32, and this is what acts as the launcher for the Java application (UNLESS there's a java.exe earlier in the PATH, and the Java app is run from the command-line). This is why File(".") keeps returning C:\Windows\system32, and why running examples from macOS or *nix implementations keep coming back with different results from Windows.

Unfortunately, there's really no universally correct answer to this one, as far as I have found in twenty years of Java coding unless you want to create your own native launcher executable using JNI Invocation, and get the current working directory from the native launcher code when it's launched. Everything else is going to have at least some nuance that could break under certain situations.

ls by default previews the files sorted by name. (ls options can be used to sort by date, size, ...)

files = list(os.popen("ls"))
files = [file.strip("\n") for file in files]

Using ls would have much better performance when the directory contains so many files.

using latest jquery mutation

                        var attributeValue = jQuery(mutation.target).prop(mutation.attributeName);
                        if (attributeValue.indexOf("search-class") >= 0){

A couple things

(a) you cant have both background-color and background, background will always win. in the example below, i combined them through shorthand, but this will produce the color only as a fallback method when the image does not show.

(b) no-scroll does not work, i don't believe it is a valid property of a background-image. try something like fixed:

.button:after {
    content: "";
    width: 30px;
    height: 30px;
    background:red url("http://www.gentleface.com/i/free_toolbar_icons_16x16_black.png") no-repeat -30px -50px fixed;
    top: 10px;
    right: 5px;
    position: absolute;
    display: inline-block;
}

I updated your jsFiddle to this and it showed the image.

Just adding my answer for the case where there are multiple versions of PHP installed in your system, and you are sure that you have already installed the php-curl package, and yet Apache is still giving you the same error.

curl_init() undefined even if php-curl is enabled in Php 7.

Also be sure your app is subclassing MultiDexApplication

import android.support.multidex.MultiDexApplication

class App : MultiDexApplication()

or if not subclassing Application class, add to AndroidManifest.xml

<application
  android:name="android.support.multidex.MultiDexApplication"

i had the same problem before

the error code 3417 : the SQL SERVER cannot start the master database, without master db SQL SERVER can't start MSSQLSERVER_3417

The master database records all the system-level information for a SQL Server system. This includes instance-wide metadata such as logon accounts, endpoints, linked servers, and system configuration settings. In SQL Server, system objects are no longer stored in the master database; instead, they are stored in the Resource database. Also, master is the database that records the existence of all other databases and the location of those database files and records the initialization information for SQL Server. Therefore, SQL Server cannot start if the master database is unavailable MSDN Master DB so you need to reconfigure all settings after restoring master db

solutions

• replace master mdf and ldf files with the same files from another instance of sql Server as long as its the same version reference
• Rebuild System Databases refrence
• reinstall sql server

Explicitly specifying the max_iter resolves the warning as the default max_iter is 100. [For Logistic Regression].

 logreg = LogisticRegression(max_iter=1000)

Mac OS X uses large amounts of C++ inside some libraries, but it isn't exposed as they're afraid of the ABI breaking.

Cast the operands to floats:

float ans = (float)a / (float)b;

a.h:

#ifndef A_H
#define A_H

struct a { 
    int i;
    struct b {
        int j;
    }
};

#endif

there you go, now you just need to include a.h to the files where you want to use this structure.

Thanks for the clues provided by you guys, especially @SmartLemon, I got the solution. In case someone else need it, I put my final solution here( to find the first listed external SD card ):

public File getExternalSDCardDirectory()
{
    File innerDir = Environment.getExternalStorageDirectory();
    File rootDir = innerDir.getParentFile();
    File firstExtSdCard = innerDir ;
    File[] files = rootDir.listFiles();
    for (File file : files) {
        if (file.compareTo(innerDir) != 0) {
            firstExtSdCard = file;
            break;
        }
    }
    //Log.i("2", firstExtSdCard.getAbsolutePath().toString());
    return firstExtSdCard;
}

If no external SD card there, then it returns the on board storage. I will use it if the sdcard is not exist, you may need to change it.

This provided a simple solution: Set data in Select2 after insert with AJAX

$("#select2").select2('data', {id: newID, text: newText});      

Based on your folder structure, try import like this in index.js:

import { AppContainer } from './App/AppContainer';

If you are using a named export, that is if you are doing:

export class AppContainer [...]

If you are using a default export, such as:

export default class AppContainer [...]

The object destructuring will fail. You have to do instead:

import AppContainer from './App/AppContainer';

Do i really have to copy all constructors from Foo into Bar and Bah? And then if i change a constructor signature in Foo, do i have to update it in Bar and Bah?

Yes, if you use constructors to create instances.

Is there no way to inherit constructors?

Nope.

Is there no way to encourage code reuse?

Well, I won't get into whether inheriting constructors would be a good or bad thing and whether it would encourage code reuse, since we don't have them and we're not going to get them. :-)

But here in 2014, with the current C#, you can get something very much like inherited constructors by using a generic create method instead. It can be a useful tool to have in your belt, but you wouldn't reach for it lightly. I reached for it recently when faced with needing to pass something into the constructor of a base type used in a couple of hundred derived classes (until recently, the base didn't need any arguments, and so the default constructor was fine — the derived classes didn't declare constructors at all, and got the automatically-supplied one).

It looks like this:

// In Foo:
public T create<T>(int i) where: where T : Foo, new() {
    T obj = new T();
    // Do whatever you would do with `i` in `Foo(i)` here, for instance,
    // if you save it as a data member;  `obj.dataMember = i;`
    return obj;
}

That says that you can call the generic create function using a type parameter which is any subtype of Foo that has a zero-arguments constructor.

Then, instead of doing Bar b new Bar(42), you'd do this:

var b = Foo.create<Bar>(42);
// or
Bar b = Foo.create<Bar>(42);
// or
var b = Bar.create<Bar>(42); // But you still need the <Bar> bit
// or
Bar b = Bar.create<Bar>(42);

There I've shown the create method being on Foo directly, but of course it could be in a factory class of some sort, if the information it's setting up can be set by that factory class.

Just for clarity: The name create isn't important, it could be makeThingy or whatever else you like.

Full Example

using System.IO;
using System;

class Program
{
    static void Main()
    {
        Bar b1 = Foo.create<Bar>(42);
        b1.ShowDataMember("b1");

        Bar b2 = Bar.create<Bar>(43); // Just to show `Foo.create` vs. `Bar.create` doesn't matter
        b2.ShowDataMember("b2");
    }

    class Foo
    {
        public int DataMember { get; private set; }

        public static T create<T>(int i) where T: Foo, new()
        {
            T obj = new T();
            obj.DataMember = i;
            return obj;
        }
    }

    class Bar : Foo
    {
        public void ShowDataMember(string prefix)
        {
            Console.WriteLine(prefix + ".DataMember = " + this.DataMember);
        }
    }
}

setInterval(
  function(){ widget.Rotator.rotate() },
  5000
);

Or:

setInterval(
  widget.Rotator.rotate.bind(widget.Rotator),
  5000
);

Even though there is a bool (short for boolean) data type in C++. But in C++, any nonzero value is a true value including negative numbers. A 0 (zero) is treated as false. Where as in JAVA there is a separate data type boolean for true and false.

Try looking here: Best way to get application folder path

To quote from there:

System.IO.Directory.GetCurrentDirectory() returns the current directory, which may or may not be the folder where the application is located. The same goes for Environment.CurrentDirectory. In case you are using this in a DLL file, it will return the path of where the process is running (this is especially true in ASP.NET).

in jquery we have to use selector($) to declare variables

var test=$("<%=ddl.ClientId%>");

here we can get the id of drop down to j query variable

How about

apply(df, 1, function(r) any(r %in% c("M017", "M018")))

The ith element will be TRUE if the ith row contains one of the values, and FALSE otherwise. Or, if you want just the row numbers, enclose the above statement in which(...).

You may also use this

divID = "question-" + (i*1+1); 

to be sure that i is converted to integer.

In Bootstrap the active class needs to be applied to the <li> element and not the <a>. See the first example here: http://getbootstrap.com/components/#navbar

The way you handle your UI style based on what is active or not has nothing to do with ASP.NET MVC's ActionLink helper. This is the proper solution to follow how the Bootstrap framework was built.

<ul class="nav navbar-nav">
    <li class="active">@Html.ActionLink("Home", "Index", "Home")</li>
    <li>@Html.ActionLink("About", "About", "Home")</li>
    <li>@Html.ActionLink("Contact", "Contact", "Home")</li>
</ul>

Edit:

Since you will most likely be reusing your menu on multiple pages, it would be smart to have a way to apply that selected class automatically based on the current page rather than copy the menu multiple times and do it manually.

The easiest way is to simply use the values contained in ViewContext.RouteData, namely the Action and Controller values. We could build on what you currently have with something like this:

<ul class="nav navbar-nav">
    <li class="@(ViewContext.RouteData.Values["Action"].ToString() == "Index" ? "active" : "")">@Html.ActionLink("Home", "Index", "Home")</li>
    <li class="@(ViewContext.RouteData.Values["Action"].ToString() == "About" ? "active" : "")">@Html.ActionLink("About", "About", "Home")</li>
    <li class="@(ViewContext.RouteData.Values["Action"].ToString() == "Contact" ? "active" : "")">@Html.ActionLink("Contact", "Contact", "Home")</li>
</ul>

It's not pretty in code, but it'll get the job done and allow you to extract your menu into a partial view if you like. There are ways to do this in a much cleaner way, but since you're just getting started I'll leave it at that. Best of luck learning ASP.NET MVC!

Late edit:

This question seems to be getting a bit of traffic so I figured I'd throw in a more elegant solution using an HtmlHelper extension.

Edit 03-24-2015: Had to rewrite this method to allow for multiple actions and controllers triggering the selected behavior, as well as handling for when the method is called from a child action partial view, thought I'd share the update!

public static string IsSelected(this HtmlHelper html, string controllers = "", string actions = "", string cssClass = "selected")
{
    ViewContext viewContext = html.ViewContext;
    bool isChildAction = viewContext.Controller.ControllerContext.IsChildAction;

    if (isChildAction)
        viewContext = html.ViewContext.ParentActionViewContext;

    RouteValueDictionary routeValues = viewContext.RouteData.Values;
    string currentAction = routeValues["action"].ToString();
    string currentController = routeValues["controller"].ToString();

    if (String.IsNullOrEmpty(actions))
        actions = currentAction;

    if (String.IsNullOrEmpty(controllers))
        controllers = currentController;

    string[] acceptedActions = actions.Trim().Split(',').Distinct().ToArray();
    string[] acceptedControllers = controllers.Trim().Split(',').Distinct().ToArray();

    return acceptedActions.Contains(currentAction) && acceptedControllers.Contains(currentController) ?
        cssClass : String.Empty;
}

Works with .NET Core:

public static string IsSelected(this IHtmlHelper htmlHelper, string controllers, string actions, string cssClass = "selected")
{
    string currentAction = htmlHelper.ViewContext.RouteData.Values["action"] as string;
    string currentController = htmlHelper.ViewContext.RouteData.Values["controller"] as string;

    IEnumerable<string> acceptedActions = (actions ?? currentAction).Split(',');
    IEnumerable<string> acceptedControllers = (controllers ?? currentController).Split(',');

    return acceptedActions.Contains(currentAction) && acceptedControllers.Contains(currentController) ?
        cssClass : String.Empty;
}

Sample usage:

<ul>
    <li class="@Html.IsSelected(actions: "Home", controllers: "Default")">
        <a href="@Url.Action("Home", "Default")">Home</a>
    </li>
    <li class="@Html.IsSelected(actions: "List,Detail", controllers: "Default")">
        <a href="@Url.Action("List", "Default")">List</a>
    </li>
</ul>

Brand new to programming in general and working through an online tutorial. I was asked to do this as well, but only using the methods I had learned so far (basically strings and loops). Not sure if this adds any value here, and I know this isn't how you would do it, but I got it to work with this:

needle = input()
haystack = input()
counter = 0
n=-1
for i in range (n+1,len(haystack)+1):
   for j in range(n+1,len(haystack)+1):
      n=-1
      if needle != haystack[i:j]:
         n = n+1
         continue
      if needle == haystack[i:j]:
         counter = counter + 1
print (counter)

Building up on Dmitri Pavlutin and joshua.paling answers, here's an extended version that extracts the base64 content (removes the metadata at the beginning) and also ensures padding is done correctly.

function getBase64(file) {
  return new Promise((resolve, reject) => {
    const reader = new FileReader();
    reader.readAsDataURL(file);
    reader.onload = () => {
      let encoded = reader.result.toString().replace(/^data:(.*,)?/, '');
      if ((encoded.length % 4) > 0) {
        encoded += '='.repeat(4 - (encoded.length % 4));
      }
      resolve(encoded);
    };
    reader.onerror = error => reject(error);
  });
}

I had a similar error with the following code:-

foreach($myvar as $key => $value){
    $query = "SELECT stuff
            FROM table
            WHERE col1 = '$criteria1'
            AND col2 = '$criteria2'";

    $result = mysql_query($query) or die('Could not execute query - '.mysql_error(). __FILE__. __LINE__. $query);               
    $point_values = mysql_fetch_assoc($result);
    $top_five_actions[$key] += $point_values; //<--- Problem Line       
}

It turned out that my $point_values variable was occasionally returning false which caused the problem so I fixed it by wrapping it in mysql_num_rows check:-

if(mysql_num_rows($result) > 0) {
        $point_values = mysql_fetch_assoc($result);
        $top_five_actions[$key] += $point_values;
}

Not sure if this helps though?

Cheers

Map reduce is a framework that was developed to process massive amounts of data efficiently. For example, if we have 1 million records in a dataset, and it is stored in a relational representation - it is very expensive to derive values and perform any sort of transformations on these.

For Example In SQL, Given the Date of Birth, to find out How many people are of age > 30 for a million records would take a while, and this would only increase in order of magnitute when the complexity of the query increases. Map Reduce provides a cluster based implementation where data is processed in a distributed manner

Here is a wikipedia article explaining what map-reduce is all about

Another good example is Finding Friends via map reduce can be a powerful example to understand the concept, and a well used use-case.

Personally, found this link quite useful to understand the concept

Copying the explanation provided in the blog (In case the link goes stale)

Finding Friends

MapReduce is a framework originally developed at Google that allows for easy large scale distributed computing across a number of domains. Apache Hadoop is an open source implementation.

I'll gloss over the details, but it comes down to defining two functions: a map function and a reduce function. The map function takes a value and outputs key:value pairs. For instance, if we define a map function that takes a string and outputs the length of the word as the key and the word itself as the value then map(steve) would return 5:steve and map(savannah) would return 8:savannah. You may have noticed that the map function is stateless and only requires the input value to compute it's output value. This allows us to run the map function against values in parallel and provides a huge advantage. Before we get to the reduce function, the mapreduce framework groups all of the values together by key, so if the map functions output the following key:value pairs:

3 : the
3 : and
3 : you
4 : then
4 : what
4 : when
5 : steve
5 : where
8 : savannah
8 : research

They get grouped as:

3 : [the, and, you]
4 : [then, what, when]
5 : [steve, where]
8 : [savannah, research]

Each of these lines would then be passed as an argument to the reduce function, which accepts a key and a list of values. In this instance, we might be trying to figure out how many words of certain lengths exist, so our reduce function will just count the number of items in the list and output the key with the size of the list, like:

3 : 3
4 : 3
5 : 2
8 : 2

The reductions can also be done in parallel, again providing a huge advantage. We can then look at these final results and see that there were only two words of length 5 in our corpus, etc...

The most common example of mapreduce is for counting the number of times words occur in a corpus. Suppose you had a copy of the internet (I've been fortunate enough to have worked in such a situation), and you wanted a list of every word on the internet as well as how many times it occurred.

The way you would approach this would be to tokenize the documents you have (break it into words), and pass each word to a mapper. The mapper would then spit the word back out along with a value of 1. The grouping phase will take all the keys (in this case words), and make a list of 1's. The reduce phase then takes a key (the word) and a list (a list of 1's for every time the key appeared on the internet), and sums the list. The reducer then outputs the word, along with it's count. When all is said and done you'll have a list of every word on the internet, along with how many times it appeared.

Easy, right? If you've ever read about mapreduce, the above scenario isn't anything new... it's the "Hello, World" of mapreduce. So here is a real world use case (Facebook may or may not actually do the following, it's just an example):

Facebook has a list of friends (note that friends are a bi-directional thing on Facebook. If I'm your friend, you're mine). They also have lots of disk space and they serve hundreds of millions of requests everyday. They've decided to pre-compute calculations when they can to reduce the processing time of requests. One common processing request is the "You and Joe have 230 friends in common" feature. When you visit someone's profile, you see a list of friends that you have in common. This list doesn't change frequently so it'd be wasteful to recalculate it every time you visited the profile (sure you could use a decent caching strategy, but then I wouldn't be able to continue writing about mapreduce for this problem). We're going to use mapreduce so that we can calculate everyone's common friends once a day and store those results. Later on it's just a quick lookup. We've got lots of disk, it's cheap.

Assume the friends are stored as Person->[List of Friends], our friends list is then:

A -> B C D
B -> A C D E
C -> A B D E
D -> A B C E
E -> B C D

Each line will be an argument to a mapper. For every friend in the list of friends, the mapper will output a key-value pair. The key will be a friend along with the person. The value will be the list of friends. The key will be sorted so that the friends are in order, causing all pairs of friends to go to the same reducer. This is hard to explain with text, so let's just do it and see if you can see the pattern. After all the mappers are done running, you'll have a list like this:

For map(A -> B C D) :

(A B) -> B C D
(A C) -> B C D
(A D) -> B C D

For map(B -> A C D E) : (Note that A comes before B in the key)

(A B) -> A C D E
(B C) -> A C D E
(B D) -> A C D E
(B E) -> A C D E
For map(C -> A B D E) :

(A C) -> A B D E
(B C) -> A B D E
(C D) -> A B D E
(C E) -> A B D E
For map(D -> A B C E) :

(A D) -> A B C E
(B D) -> A B C E
(C D) -> A B C E
(D E) -> A B C E
And finally for map(E -> B C D):

(B E) -> B C D
(C E) -> B C D
(D E) -> B C D
Before we send these key-value pairs to the reducers, we group them by their keys and get:

(A B) -> (A C D E) (B C D)
(A C) -> (A B D E) (B C D)
(A D) -> (A B C E) (B C D)
(B C) -> (A B D E) (A C D E)
(B D) -> (A B C E) (A C D E)
(B E) -> (A C D E) (B C D)
(C D) -> (A B C E) (A B D E)
(C E) -> (A B D E) (B C D)
(D E) -> (A B C E) (B C D)

Each line will be passed as an argument to a reducer. The reduce function will simply intersect the lists of values and output the same key with the result of the intersection. For example, reduce((A B) -> (A C D E) (B C D)) will output (A B) : (C D) and means that friends A and B have C and D as common friends.

The result after reduction is:

(A B) -> (C D)
(A C) -> (B D)
(A D) -> (B C)
(B C) -> (A D E)
(B D) -> (A C E)
(B E) -> (C D)
(C D) -> (A B E)
(C E) -> (B D)
(D E) -> (B C)

Now when D visits B's profile, we can quickly look up (B D) and see that they have three friends in common, (A C E).

If I understand the question correctly, you want to detect when the h_no doesn't increase and then increment the class. (I'm going to walk through how I solved this problem, there is a self-contained function at the end.)

Working

We only care about the h_no column for the moment, so we can extract that from the data frame:

> h_no <- data$h_no

We want to detect when h_no doesn't go up, which we can do by working out when the difference between successive elements is either negative or zero. R provides the diff function which gives us the vector of differences:

> d.h_no <- diff(h_no)
> d.h_no
 [1]  1  1  1 -3  1  1  1  1  1  1 -6  1  1  1

Once we have that, it is a simple matter to find the ones that are non-positive:

> nonpos <- d.h_no <= 0
> nonpos
 [1] FALSE FALSE FALSE  TRUE FALSE FALSE FALSE FALSE FALSE FALSE  TRUE FALSE
[13] FALSE FALSE

In R, TRUE and FALSE are basically the same as 1 and 0, so if we get the cumulative sum of nonpos, it will increase by 1 in (almost) the appropriate spots. The cumsum function (which is basically the opposite of diff) can do this.

> cumsum(nonpos)
 [1] 0 0 0 1 1 1 1 1 1 1 2 2 2 2

But, there are two problems: the numbers are one too small; and, we are missing the first element (there should be four in the first class).

The first problem is simply solved: 1+cumsum(nonpos). And the second just requires adding a 1 to the front of the vector, since the first element is always in class 1:

 > classes <- c(1, 1 + cumsum(nonpos))
 > classes
  [1] 1 1 1 1 2 2 2 2 2 2 2 3 3 3 3

Now, we can attach it back onto our data frame with cbind (by using the class= syntax, we can give the column the class heading):

 > data_w_classes <- cbind(data, class=classes)

And data_w_classes now contains the result.

Final result

We can compress the lines together and wrap it all up into a function to make it easier to use:

classify <- function(data) {
   cbind(data, class=c(1, 1 + cumsum(diff(data$h_no) <= 0)))
}

Or, since it makes sense for the class to be a factor:

classify <- function(data) {
   cbind(data, class=factor(c(1, 1 + cumsum(diff(data$h_no) <= 0))))
}

You use either function like:

> classified <- classify(data) # doesn't overwrite data
> data <- classify(data) # data now has the "class" column

(This method of solving this problem is good because it avoids explicit iteration, which is generally recommend for R, and avoids generating lots of intermediate vectors and list etc. And also it's kinda neat how it can be written on one line :) )

found one more way to do it using the boto:

from boto.s3.connection import S3Connection, Bucket, Key

conn = S3Connection(AWS_ACCESS_KEY, AWS_SECERET_KEY)

b = Bucket(conn, S3_BUCKET_NAME)

k = Key(b)

k.key = 'images/my-images/'+filename

b.delete_key(k)

I had this error message when trying "hello world" like things with Qt. The problems went away by correctly running the qt moc (meta object compiler) and compiling+including these moc-generated files correctly.

If the project came with a Visual Studio project file, then that should already be configured to find the headers for you. If not, you'll have to add the include file directory to the project settings by right-clicking the project and selecting Properties, clicking on "C/C++", and adding the directory containing the include files to the "Additional Include Directories" edit box.

the provided solutions seem a little complex? this might help:

https://msdn.microsoft.com/en-us/library/ms174420.aspx

select
   mystuff,
   DATEPART ( year, MyDateColumn ) as yearnr,
   DATEPART ( week, MyDateColumn ) as weeknr
from mytable
group by ...etc

i found another solution:

1. start session in TEAM
2. go to SOURCE CONTROL and select WORKSPACE (mark in red)
3. then Add new Workspace... why?
4. because you dont work in the same workspace whey you change your account in TFS (i dont know why)
5. and ready to MAP your project again.

Its 100% guaranteed to work.

The new Chosen libraries don't use the liszt. I used the following:

document.getElementById('autoship_option').selectedIndex = 0;
$("#autoship_option").trigger("chosen:updated");

It's /public_html/stats/*.

$ ~/myrepo> ls public_html/stats/
bar baz foo
$ ~/myrepo> cat .gitignore

# Initial commit
#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#   .gitignore
nothing added to commit but untracked files present (use "git add" to track)

This was already mentioned in a comment by benvoliot above. But, I think it's worth a top-level post because it sure had me scratching my head. I'm posting this in case it helps someone else out.

I wrote a simple test client and the CoreConnectionPNames.CONNECTION_TIMEOUT timeout works perfectly in that case. The request gets canceled if the server doesn't respond.

Inside the server code I was actually trying to test however, the identical code never times out.

Changing it to time out on the socket connection activity (CoreConnectionPNames.SO_TIMEOUT) rather than the HTTP connection (CoreConnectionPNames.CONNECTION_TIMEOUT) fixed the problem for me.

Also, read the Apache docs carefully: http://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/params/CoreConnectionPNames.html#CONNECTION_TIMEOUT

Note the bit that says

Please note this parameter can only be applied to connections that are bound to a particular local address.

I hope that saves someone else all the head scratching I went through. That will teach me not to read the documentation thoroughly!

I had this issue upgrading from Java 8 to 11. After adding this dependency, my app launched without issue:

<dependency>

    <version>3.25.0-GA</version>
</dependency>

Ok, adding to the answers stated you might be also looking for

IEnumerable<string> m_oEnum = Enumerable.Empty<string>();

or

IEnumerable<string> m_oEnum = new string[]{};

This problem appear if two software use same port for connecting to the server
try to close the port by cmd according to your operating system
then reboot your Android studio or your Eclipse or your Software.

The simplest is using the OpenCV Mat class:

img=cv::Scalar(blue_value, green_value, red_value);

where img was defined as a cv::Mat.

MYISAM:

1. MYISAM supports Table-level Locking
2. MyISAM designed for need of speed
3. MyISAM does not support foreign keys hence we call MySQL with MYISAM is DBMS
4. MyISAM stores its tables, data and indexes in diskspace using separate three different files. (tablename.FRM, tablename.MYD, tablename.MYI)
5. MYISAM not supports transaction. You cannot commit and rollback with MYISAM. Once you issue a command it’s done.
6. MYISAM supports fulltext search
7. You can use MyISAM, if the table is more static with lots of select and less update and delete.

INNODB:

1. InnoDB supports Row-level Locking
2. InnoDB designed for maximum performance when processing high volume of data
3. InnoDB support foreign keys hence we call MySQL with InnoDB is RDBMS
4. InnoDB stores its tables and indexes in a tablespace
5. InnoDB supports transaction. You can commit and rollback with InnoDB

Doxygen creates inheritance diagrams but I dont think it will create an entire class hierachy. It does allow you to use the GraphViz tool. If you use the Doxygen GUI frontend tool you will find the relevant options in Step2: -> Wizard tab -> Diagrams. The DOT relation options are under the Expert Tab.

As simple as this

x = "some data you want to return"
return x, 200, {'Content-Type': 'text/css; charset=utf-8'}

Hope it helps

Update: Use this method because it will work with both python 2.x and python 3.x

and secondly it also eliminates multiple header problem.

from flask import Response
r = Response(response="TEST OK", status=200, mimetype="application/xml")
r.headers["Content-Type"] = "text/xml; charset=utf-8"
return r

To create all intermediate-level destination directories you could use os.makedirs() before copying:

import os
import shutil

srcfile = 'a/long/long/path/to/file.py'
dstroot = '/home/myhome/new_folder'


assert not os.path.isabs(srcfile)
dstdir =  os.path.join(dstroot, os.path.dirname(srcfile))

os.makedirs(dstdir) # create all directories, raise an error if it already exists
shutil.copy(srcfile, dstdir)

See "Is there a way to define variables of two types in for loop?" for another way involving nesting multiple for loops. The advantage of the other way over Georg's "struct trick" is that it (1) allows you to have a mixture of static and non-static local variables and (2) it allows you to have non-copyable variables. The downside is that it is far less readable and may be less efficient.

select DATEDIFF(dd, '12/30/1899', mydatefield)

If you don't want to add id's to your data, you could track by the index in the array, which will cause the items to be keyed by their position in the array instead of their value.

Like this:

var myArray = [1,1,1,1,1];

<li ng-repeat="item in myArray track by $index">

In Python, you can't just embed arbitrary Python expressions into literal strings and have it substitute the value of the string. You need to either:

sys.stderr.write("Usage: " + sys.argv[0])

or

sys.stderr.write("Usage: %s" % sys.argv[0])

Also, you may want to consider using the following syntax of print (for Python earlier than 3.x):

print >>sys.stderr, "Usage:", sys.argv[0]

Using print arguably makes the code easier to read. Python automatically adds a space between arguments to the print statement, so there will be one space after the colon in the above example.

In Python 3.x, you would use the print function:

print("Usage:", sys.argv[0], file=sys.stderr)

Finally, in Python 2.6 and later you can use .format:

print >>sys.stderr, "Usage: {0}".format(sys.argv[0])

The way that Magento themes handle actual url's is as such (in view partials - phtml files):

echo $this->getSkinUrl('images/logo.png');

If you need the actual base path on disk to the image directory use:

echo Mage::getBaseDir('skin');

Some more base directory types are available in this great blog post:

http://alanstorm.com/magento_base_directories

position: absolute will position the element by coordinates, relative to the closest positioned ancestor, i.e. the closest parent which isn't position: static.

Have your four divs nested inside the target div, give the target div position: relative, and use position: absolute on the others.

Structure your HTML similar to this:

<div id="container">
  <div class="top left"></div>
  <div class="top right"></div>
  <div class="bottom left"></div>
  <div class="bottom right"></div>
</div>

And this CSS should work:

#container {
  position: relative;
}

#container > * {
  position: absolute;
}

.left {
  left: 0;
}

.right {
  right: 0;
}

.top {
  top: 0;
}

.bottom {
  bottom: 0;
}

...

As far as I can tell there is no upper limit in 2008.

In SQL Server 2005 the code in your question fails on the assignment to the @GGMMsg variable with

Attempting to grow LOB beyond maximum allowed size of 2,147,483,647 bytes.

the code below fails with

REPLICATE: The length of the result exceeds the length limit (2GB) of the target large type.

However it appears these limitations have quietly been lifted. On 2008

DECLARE @y VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),92681); 

SET @y = REPLICATE(@y,92681);

SELECT LEN(@y) 

Returns

8589767761

I ran this on my 32 bit desktop machine so this 8GB string is way in excess of addressable memory

Running

select internal_objects_alloc_page_count
from sys.dm_db_task_space_usage
WHERE session_id = @@spid

Returned

internal_objects_alloc_page_co 
------------------------------ 
2144456    

so I presume this all just gets stored in LOB pages in tempdb with no validation on length. The page count growth was all associated with the SET @y = REPLICATE(@y,92681); statement. The initial variable assignment to @y and the LEN calculation did not increase this.

The reason for mentioning this is because the page count is hugely more than I was expecting. Assuming an 8KB page then this works out at 16.36 GB which is obviously more or less double what would seem to be necessary. I speculate that this is likely due to the inefficiency of the string concatenation operation needing to copy the entire huge string and append a chunk on to the end rather than being able to add to the end of the existing string. Unfortunately at the moment the .WRITE method isn't supported for varchar(max) variables.

I've also tested the behaviour with concatenating nvarchar(max) + nvarchar(max) and nvarchar(max) + varchar(max). Both of these allow the 2GB limit to be exceeded. Trying to then store the results of this in a table then fails however with the error message Attempting to grow LOB beyond maximum allowed size of 2147483647 bytes. again. The script for that is below (may take a long time to run).

DECLARE @y1 VARCHAR(MAX) = REPLICATE(CAST('X' AS VARCHAR(MAX)),2147483647); 
SET @y1 = @y1 + @y1;
SELECT LEN(@y1), DATALENGTH(@y1)  /*4294967294, 4294967292*/


DECLARE @y2 NVARCHAR(MAX) = REPLICATE(CAST('X' AS NVARCHAR(MAX)),1073741823); 
SET @y2 = @y2 + @y2;
SELECT LEN(@y2), DATALENGTH(@y2)  /*2147483646, 4294967292*/

I want to share my solution for those who are using react-router-dom v5 since none of these v4 solutions did the work for me.

What solved my problem was installing react-router-scroll-top and put the wrapper in the <App /> like this:

const App = () => (
  <Router>
    <ScrollToTop>
      <App/>
    </ScrollToTop>
  </Router>
)

and that's it! it worked!

If you are a developer, this is what you need to do:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />

If you just want to see your DB & Tables then the esiest way is to use Stetho. Pretty cool tool for every Android developer who uses SQLite buit by Facobook developed.

Steps to use the tool

1. Add below dependeccy in your application`s gradle file (Module: app)

'compile 'com.facebook.stetho:stetho:1.4.2'

2. Add below lines of code in your Activity onCreate() method

@Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 Stetho.initializeWithDefaults(this);
 setContentView(R.layout.activity_main);
 }

Now, build your application & When the app is running, you can browse your app database, by opening chrome in the url:

chrome://inspect/#devices

Screenshots of the same are as below_

Hope this will help to all! :)

For most software that isn't actually string-processing software, program logic ought not to depend on the content of string variables. Whenever I see something like this in a program:

if (s == "value")

I get a bad feeling. Why is there a string literal in this method? What's setting s? Does it know that logic depends on the value of the string? Does it know that it has to be lower case to work? Should I be fixing this by changing it to use String.Compare? Should I be creating an Enum and parsing into it?

From this perspective, one gets to a philosophy of code that's pretty simple: you avoid examining a string's contents wherever possible. Comparing a string to String.Empty is really just a special case of comparing it to a literal: it's something to avoid doing unless you really have to.

Knowing this, I don't blink when I see something like this in our code base:

string msg = Validate(item);
if (msg != null)
{
   DisplayErrorMessage(msg);
   return;
}

I know that Validate would never return String.Empty, because we write better code than that.

Of course, the rest of the world doesn't work like this. When your program is dealing with user input, databases, files, and so on, you have to account for other philosophies. There, it's the job of your code to impose order on chaos. Part of that order is knowing when an empty string should mean String.Empty and when it should mean null.

(Just to make sure I wasn't talking out of my ass, I just searched our codebase for `String.IsNullOrEmpty'. All 54 occurrences of it are in methods that process user input, return values from Python scripts, examine values retrieved from external APIs, etc.)

My solution. The JSONServer is a class I wrote for running an HttpListener server in a console window.

class Program
{
    public static JSONServer srv = null;

    static void Main(string[] args)
    {
        Console.WriteLine("NLPS Core Server");

        srv = new JSONServer(100);
        srv.Start();

        InputLoopProcessor();

        while(srv.IsRunning)
        {
            Thread.Sleep(250);
        }

    }

    private static async Task InputLoopProcessor()
    {
        string line = "";

        Console.WriteLine("Core NLPS Server: Started on port 8080. " + DateTime.Now);

        while(line != "quit")
        {
            Console.Write(": ");
            line = Console.ReadLine().ToLower();
            Console.WriteLine(line);

            if(line == "?" || line == "help")
            {
                Console.WriteLine("Core NLPS Server Help");
                Console.WriteLine("    ? or help: Show this help.");
                Console.WriteLine("    quit: Stop the server.");
            }
        }
        srv.Stop();
        Console.WriteLine("Core Processor done at " + DateTime.Now);

    }
}

There are some more actions you should consider:

• Remove Registry Entries for MS Distributed Transaction Coordinator (MSDTC)

  Note: on the Internet I found this step only at a single (private) page. I don't know if it is required/working or if it breaks anything on your PC.

  • Open Regedit
  • Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\MSDTC\MTxOCI
  • Add an x before each string for OracleOciLib, OracleSqlLib, and OracleXaLib
  • Navigate to HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\MSDTC\MTxOCI
  • Add an x before each string for OracleOciLib, OracleSqlLib, and OracleXaLib

  Otherwise these files, if they exist, will still be in use next time you reboot, and unable to be deleted.

• Remove environment variable ORACLE_HOME, ORACLE_BASE, TNS_ADMIN, NLS_LANG if exist

  Check also Oracle doc to find all Oracle related environment variables, however apart from variables listed above they are very rarely used on Windows Client: Oracle Environment Variables

• Unregister oci.dll

  • Open a command line window (Start Menu -> Run... -> cmd)

  • Enter regsvr32 /u oci.dll, resp. %windir%\SysWOW64\regsvr32 /u oci.dll

  • In some cases the file %ORACLE_HOME%\bin\oci.dll is locked and you cannot delete it. In such case rename the file (e.g. to oci.dll.x) and reboot the PC, afterwards you can delete it.

• Remove Oracle .NET assemblies from Global Assembly Cache (GAC). You do this typically with the gacutil utility, if available on your system. Would be like this:

  gacutil /u Policy.10.1.Oracle.DataAccess
  gacutil /u Policy.10.2.Oracle.DataAccess
  gacutil /u Policy.1.102.Oracle.DataAccess
  gacutil /u Policy.1.111.Oracle.DataAccess
  
  gacutil /u Policy.2.102.Oracle.DataAccess
  gacutil /u Policy.2.111.Oracle.DataAccess
  gacutil /u Policy.2.112.Oracle.DataAccess
  gacutil /u Policy.2.121.Oracle.DataAccess
  gacutil /u Policy.2.122.Oracle.DataAccess
  
  gacutil /u Policy.4.112.Oracle.DataAccess
  gacutil /u Policy.4.121.Oracle.DataAccess
  gacutil /u Policy.4.122.Oracle.DataAccess
  
  gacutil /u Oracle.DataAccess
  gacutil /u Oracle.DataAccess.resources
  
  gacutil /u Policy.4.121.Oracle.ManagedDataAccess
  gacutil /u Policy.4.122.Oracle.ManagedDataAccess
  gacutil /u Oracle.ManagedDataAccess
  gacutil /u Oracle.ManagedDataAccess.resources
  gacutil /u Oracle.ManagedDataAccessDTC
  gacutil /u Oracle.ManagedDataAccessIOP
  gacutil /u Oracle.ManagedDataAccess.EntityFramework
  

  • Entry System.Data.OracleClient should not be removed, this one is installed by Microsoft - not an Oracle component!

  • Instead of gacutil /u ... you can also use OraProvCfg /action:ungac /providerpath:... if OraProvCfg is still available on your system. You may find it at %ORACLE_HOME%\odp.net\managed\x64\OraProvCfg.exe.

• With a text editor, open XML Config file %SYSTEMROOT%\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config and delete branch <oracle.manageddataaccess.client>, if existing.

  • Do the same with:

    %SYSTEMROOT%\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config
    %SYSTEMROOT%\Microsoft.NET\Framework\v4.0.30319\Config\machine.config
    %SYSTEMROOT%\Microsoft.NET\Framework64\v4.0.30319\Config\web.config
    %SYSTEMROOT%\Microsoft.NET\Framework\v4.0.30319\Config\web.config
    

  Instead of editing the XML Config file manually you can also run (if OraProvCfg.exe is still available on your system):

  %ORACLE_HOME%\odp.net\managed\x64\OraProvCfg.exe /action:unconfig /product:odpm /frameworkversion:v4.0.30319 
  %ORACLE_HOME%\odp.net\managed\x86\OraProvCfg.exe /action:unconfig /product:odpm /frameworkversion:v4.0.30319
  %ORACLE_HOME%\odp.net\managed\x64\OraProvCfg.exe /action:unconfig /product:odp /frameworkversion:v4.0.30319 
  %ORACLE_HOME%\odp.net\managed\x86\OraProvCfg.exe /action:unconfig /product:odp /frameworkversion:v4.0.30319
  

• Check following Registry Keys and delete them if existing

  HKLM\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v2.0.50727\AssemblyFoldersEx\ODP.Net
  HKLM\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319\AssemblyFoldersEx\ODP.Net

• Delete the Inventory folder, typically C:\Program Files\Oracle\Inventory and C:\Program Files (x86)\Oracle\Inventory

• Delete temp folders %TEMP%\deinstall\, %TEMP%\OraInstall\ and %TEMP%\CVU* (e.g %TEMP%\CVU_11.1.0.2.0_domscheit) if existing.

in Winforms, there is a Screen class you can use to get data about screen dimensions and color depth for all displays connected to the computer. Here's the docs page: http://msdn.microsoft.com/en-us/library/system.windows.forms.screen.aspx

CHANGING the screen resolution is trickier. There is a Resolution third party class that wraps the native code you'd otherwise hook into. Use its CResolution nested class to set the screen resolution to a new height and width; but understand that doing this will only work for height/width combinations the display actually supports (800x600, 1024x768, etc, not 817x435).

__file__ is absolute since Python 3.4, except when executing a script directly using a relative path:

Module __file__ attributes (and related values) should now always contain absolute paths by default, with the sole exception of __main__.__file__ when a script has been executed directly using a relative path. (Contributed by Brett Cannon in bpo-18416.)

Not sure if it resolves symlinks though.

Example of passing a relative path:

$ python script.py

I encountered the same error, and was able to solve it as follows:

1. composer diagnose to see if something is wrong with the version of composer installed
2. composer self-update to install the latest version
3. composer update to update your composer.json file.

All of the answers is true.This is another way. And I like this One

SqlCommand cmd = conn.CreateCommand()

you must notice that strings concat have a sql injection problem. Use the Parameters http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlcommand.parameters.aspx

You're probably mistaking what PHP.ini you need to edit. first, add a PHPinfo(); to a info.php, and run it from your browser.

Write down the PHP ini directory path you see in the variables list now! You will probably notice that it's different from your PHP-CLI ini file.

Enable the extension

You're done :-)

Get-Content has bad performance; it tries to read the file into memory all at once.

C# (.NET) file reader reads each line one by one

Best Performace

foreach($line in [System.IO.File]::ReadLines("C:\path\to\file.txt"))
{
       $line
}

Or slightly less performant

[System.IO.File]::ReadLines("C:\path\to\file.txt") | ForEach-Object {
       $_
}

The foreach statement will likely be slightly faster than ForEach-Object (see comments below for more information).

Now in latest pandas you can directly use df.plot.scatter function

df = pd.DataFrame([[5.1, 3.5, 0], [4.9, 3.0, 0], [7.0, 3.2, 1],
                   [6.4, 3.2, 1], [5.9, 3.0, 2]],
                  columns=['length', 'width', 'species'])
ax1 = df.plot.scatter(x='length',
                      y='width',
                      c='DarkBlue')

Probably you haven't injected $http service to your controller. There are several ways of doing that.

Please read this reference about DI. Then it gets very simple:

function MyController($scope, $http) {
   // ... your code
}

Could be due to the TCP protocol turned off.

To extrapolate a bit on the other answers (in as Beginner-friendly a way as possible):

• String objects that point to valid paths can be converted to DirectoryInfo/FileInfo objects via functions like Get-Item and Get-ChildItem.
• .Parent can only be used on a DirectoryInfo object.
• .Directory converts FileInfo object to a DirectoryInfo object, and will return null if used on any other type (even another DirectoryInfo object).
• .DirectoryName converts a FileInfo object to a String object, and will return null if used on any other type (even another String object).
• .FullName converts a DirectoryInfo/FileInfo object to a String object, and will return null if used on any other type (even another DirectoryInfo/FileInfo object).

Check the object type with the GetType Method to see what you're working with: $scriptPath.GetType()

Lastly, a quick tip that helps with making one-liners: Get-Item has the gi alias and Get-ChildItem has the gci alias.

Here is a function using recursion which will work on any arbitrary nested list.

def flatten(nested_lst):
    """ Return a list after transforming the inner lists
        so that it's a 1-D list.

    >>> flatten([[[],["a"],"a"],[["ab"],[],"abc"]])
    ['a', 'a', 'ab', 'abc']
    """
    if not isinstance(nested_lst, list):
        return(nested_lst)

    res = []
    for l in nested_lst:
        if not isinstance(l, list):
            res += [l]
        else:
            res += flatten(l)


    return(res)

>>> flatten([[[],["a"],"a"],[["ab"],[],"abc"]])
['a', 'a', 'ab', 'abc']

It's hard to give a generic answer to this. It really depends on number of factors:

• what size your row is
• what kind of data you store (strings, blobs, numbers)
• what do you do with your data (just keep it as archive, query it regularly)
• do you have indexes on your table - how many
• what's your server specs

etc.

As answered elsewhere here, 100,000 a day and thus per table is overkill - I'd suggest monthly or weekly perhaps even quarterly. The more tables you have the bigger maintenance/query nightmare it will become.

here is the correct way of using proxy along with creds..

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);

IWebProxy proxy = request.Proxy;                    
if (proxy != null)
{
    Console.WriteLine("Proxy: {0}", proxy.GetProxy(request.RequestUri));
}
else
{
    Console.WriteLine("Proxy is null; no proxy will be used");
}

WebProxy myProxy = new WebProxy();
Uri newUri = new Uri("http://20.154.23.100:8888");
// Associate the newUri object to 'myProxy' object so that new myProxy settings can be set.
myProxy.Address = newUri;
// Create a NetworkCredential object and associate it with the 
// Proxy property of request object.
myProxy.Credentials = new NetworkCredential("userName", "password");
request.Proxy = myProxy;

Thanks everyone for help... :)

The language standard simply doesn't allow for it. Labels can only be followed by statements, and declarations do not count as statements in C. The easiest way to get around this is by inserting an empty statement after your label, which relieves you from keeping track of the scope the way you would need to inside a block.

#include <stdio.h>
int main () 
{
    printf("Hello ");
    goto Cleanup;
Cleanup: ; //This is an empty statement.
    char *str = "World\n";
    printf("%s\n", str);
}

Before answering, I would like to give you some data from Wiki

Data structure alignment is the way data is arranged and accessed in computer memory. It consists of two separate but related issues: data alignment and data structure padding.

When a modern computer reads from or writes to a memory address, it will do this in word sized chunks (e.g. 4 byte chunks on a 32-bit system). Data alignment means putting the data at a memory offset equal to some multiple of the word size, which increases the system's performance due to the way the CPU handles memory.

To align the data, it may be necessary to insert some meaningless bytes between the end of the last data structure and the start of the next, which is data structure padding.

gcc provides functionality to disable structure padding. i.e to avoid these meaningless bytes in some cases. Consider the following structure:

typedef struct
{
     char Data1;
     int Data2;
     unsigned short Data3;
     char Data4;

}sSampleStruct;

sizeof(sSampleStruct) will be 12 rather than 8. Because of structure padding. By default, In X86, structures will be padded to 4-byte alignment:

typedef struct
{
     char Data1;
     //3-Bytes Added here.
     int Data2;
     unsigned short Data3;
     char Data4;
     //1-byte Added here.

}sSampleStruct;

We can use __attribute__((packed, aligned(X))) to insist particular(X) sized padding. X should be powers of two. Refer here

typedef struct
{
     char Data1;
     int Data2;
     unsigned short Data3;
     char Data4;

}__attribute__((packed, aligned(1))) sSampleStruct;  

so the above specified gcc attribute does not allow the structure padding. so the size will be 8 bytes.

If you wish to do the same for all the structures, simply we can push the alignment value to stack using #pragma

#pragma pack(push, 1)

//Structure 1
......

//Structure 2
......

#pragma pack(pop)

If you are intending on passing those integers to a function or method, consider this example:

sum(int(x) for x in numbers)

This construction is intentionally remarkably similar to list comprehensions mentioned by adamk. Without the square brackets, it's called a generator expression, and is a very memory-efficient way of passing a list of arguments to a method. A good discussion is available here: Generator Expressions vs. List Comprehension

Quick solution: Update package.json

"devDependencies": {
   ...
   "typescript": "~3.7.4",
 }

In tsconfig.json

{
    ...,
    "angularCompilerOptions": {
       ...,
       "disableTypeScriptVersionCheck": true
    }
}

then remove node_modules folder and reinstall with

npm install

__init__ does act like a constructor. You'll need to pass "self" to any class functions as the first argument if you want them to behave as non-static methods. "self" are instance variables for your class.

Does this work?

[0-9]{2}.[0-9]{2}

Unless you really want to keep the dictionary, I think the best solution is to use the csv Python module to read the file. Then, you get rows of data and you can change member_phone or whatever you want ; finally, you can use the csv module again to save the file in the same format as you opened it.

Code for reading:

import csv

with open("my_input_file.txt", "r") as f:
   reader = csv.reader(f, delimiter=":")
   lines = list(reader)

Code for writing:

with open("my_output_file.txt", "w") as f:
   writer = csv.writer(f, delimiter=":")
   writer.writerows(lines)

Of course, you need to adapt your change() function:

def change(lines):
    a = input('ID')
    for line in lines:
      if line[0] == a:
        d=str(input("phone"))
        line[3]=d
        break
    else:
      print "not"

ill find easy way to find first element in Dictionary :)

 Dictionary<string, Dictionary<string, string>> like = 
 newDictionary<string,Dictionary<string, string>>();

 foreach(KeyValuePair<string, Dictionary<string, string>> _element in like)

   break;
 }

You could use a VBA script that changes the conditional formatting of a selection (you might have to adjust the condition & formatting accordingly):

For Each i In Selection
i.FormatConditions.Delete
i.FormatConditions.Add Type:=xlCellValue, Operator:=xlLess, Formula1:="=" & i.Offset(0, -1).Address
With i.FormatConditions(1).Font
    .Bold = True
End With
Next i

Not easily done I am afraid. The problem is Css cannot replace the arrow in a select as this is rendered by the browser. But you can build a new control from div and input elements and Javascript to perform the same function as the select.

Try looking at some of the autocomplete plugins for Jquery for example.

Otherwise there is some info on the select element here:

http://www.devarticles.com/c/a/Web-Style-Sheets/Taming-the-Select/

You might consider turning your python script into a proper python daemon, as described here.

python-daemon is a good tool that can be used to run python scripts as a background daemon process rather than a forever running script. You will need to modify existing code a bit but its plain and simple.

If you are facing problems with python-daemon, there is another utility supervisor that will do the same for you, but in this case you wont have to write any code (or modify existing) as this is a out of the box solution for daemonizing processes.

When is something considered so obscene as to be something that can be regulated despite the 1st Amendment guarantee to free speech? According to Justice Potter Stewart, "I know it when I see it." The same holds here.

I hate making hard and fast rules like this because the answer changes not only depending on the size and scope of your project, but I think it changes even down to the module level. Depending on what your method is doing, or what the class is supposed to represent, it's quite possible that 2 arguments is too many and is a symptom of too much coupling.

I would suggest that by asking the question in the first place, and qualifying your question as much as you did, that you really know all of this. The best solution here is not to rely on a hard and fast number, but instead look towards design reviews and code reviews among your peers to identify areas where you have low cohesion and tight coupling.

Never be afraid to show your colleagues your work. If you are afraid to, that's probably the bigger sign that something is wrong with your code, and that you already know it.

I had trouble deleting a cookie made via JavaScript and after I added the host it worked (scroll the code below to the right to see the location.host). After clearing the cookies on a domain try the following to see the results:

if (document.cookie.length==0)
{
 document.cookie = 'name=example; expires='+new Date((new Date()).valueOf()+1000*60*60*24*15)+'; path=/; domain='+location.host;

 if (document.cookie.length==0) {alert('Cookies disabled');}
 else
 {
  document.cookie = 'name=example; expires=Thu, 01 Jan 1970 00:00:00 GMT; path=/; domain='+location.host;

  if (document.cookie.length==0) {alert('Created AND deleted cookie successfully.');}
  else {alert('document.cookies.length = '+document.cookies.length);}
 }
}

You can just do git merge <commit-number> or git cherry-pick <commit> <commit> ...

As suggested by Ryan Stewart you may also create a branch from the current HEAD:

git branch brand-name

Or just a tag:

git tag tag-name

@Ryan Cavanaugh's answer is totally ok and still valid. Still it worth to add that as of Fall'16 when we can claim that ES6 is supported by the majority of platforms it almost always better to stick to Map whenever you need associate some data with some key.

When we write let a: { [s: string]: string; } we need to remember that after typescript compiled there's not such thing like type data, it's only used for compiling. And { [s: string]: string; } will compile to just {}.

That said, even if you'll write something like:

class TrickyKey  {}

let dict: {[key:TrickyKey]: string} = {}

This just won't compile (even for target es6, you'll get error TS1023: An index signature parameter type must be 'string' or 'number'.

So practically you are limited with string or number as potential key so there's not that much of a sense of enforcing type check here, especially keeping in mind that when js tries to access key by number it converts it to string.

So it is quite safe to assume that best practice is to use Map even if keys are string, so I'd stick with:

let staff: Map<string, string> = new Map();

The variable '$$' contains the PID.

The metacharacter \b is an anchor like the caret and the dollar sign. It matches at a position that is called a "word boundary". This match is zero-length.

There are three different positions that qualify as word boundaries:

• Before the first character in the string, if the first character is a word character.
• After the last character in the string, if the last character is a word character.
• Between two characters in the string, where one is a word character and the other is not a word character.

\B is the negated version of \b. \B matches at every position where \b does not. Effectively, \B matches at any position between two word characters as well as at any position between two non-word characters.
