First is understanding that RFID is very generic term. NFC is subset of RFID technology. NFC is used for prox card, credit cards, tap and go payment system. Your phones can read and emulate NFC (Apple pay, Google pay, etc.), if they support NFC. NFC is very short distance and low power - which is why you see tap and go type usage.

The more common RFID are the tags you see here and there. They come in a wide ranges of styles, uses and frequency.

HF - high frequency tags are what they use for "chipping" animals - cattle, dogs, cats. Read range is about 12 inches and requires an external antenna that is powered the bigger the antenna the more power it needs and the further it can read.

UFH tags look similar to HF tags but have a read range of several feet.

Also HF tags come single read and multi read. UFH is exclusviely multi read.

Mutiread means when a reader is active, you can litterally read about 1700 tags in under 10 seconds.

But this is a function of the size of the antenna and how much power you can push through the reader.

As to the direct question about Android and RFID - the best way to go is to get an external handheld reader that connects to your mobile device via Bluetooth. Bluetooth libraries exist for all mobile devices - Android, Apple, Windows. From there its just a matter of the manufacturer documentation about how to open a socket to the reader and how to decode the serial information.

The TSL line of readers is very popular because you don't have to deal with reading bytes and all that low level serial jazz that other manufactures do. They have a nice set of commands that are easy to use to control the reader.

Other manufactures are basic in that you open a serial socket and then read the output like you would see in terminal app like PuTTY.

The iPhone6/6s/6+ are NOT designed to read passive NFC tags (aka Discovery Mode). There's a lot of misinformation on this topic, so I thought to provide some tangible info for developers to consider. The lack of NFC tag read support is not because of software but because of hardware. To understand why, you need to understand how NFC works. NFC works by way of Load Modulation. That means that the interrogator (PCD) emits a carrier magnetic field that energizes the passive target (PICC). With the potential generated by this carrier field, the target then is able to demodulate data coming from the interrogator and respond by modulating data over top of this very same field. The key here is that the target never creates a field of its own.

If you look at the iPhone6 teardown and parts list you will see the presence of a very small NFC loop antenna as well as the use of the AS3923 booster IC. This design was intended for custom microSD or SIM cards to enable mobile phones of old to do payments. This is the type of application where the mobile phone presents a Card Emulated credential to a high power contactless POS terminal. The POS terminal acts as the reader, energizing the iPhone6 with help from the AS3923 chip. The AS3923 block diagram clearly shows how the RX and TX modulation is boosted from a signal presented by a reader device. In other words the iPhone6 is not meant to provide a field, only to react to one. That's why it's design is only meant for NFC Card Emulation and perhaps Peer-2-Peer, but definitely not tag Discovery.

There are some alternatives to achieving tag Discovery with an iPhone6 using HW accessories. I talk about these integrations and how developers can architect solutions in this blog post. Our low power reader designs open interesting opportunities for mobile engagement that few developers are thinking about.

Disclosure: I'm the founder of Flomio, Inc., a TechStars company that delivers proximity ID hardware, software, and services for applications ranging from access control to payments.

Update: This rumor, if true, would open up the possibility for the iPhone to practically support NFC tag Discovery mode. An all glass design would not interfere with the NFC antenna as does the metal back of the current iPhone. We've attempted this design approach --albeit with cheaper materials-- on some of our custom reader designs with success so looking forward to this improvement.

Update: iOS11 has announced support for "NFC reader mode" for iPhone7/7+. Details here. API only supports reading NDEF messages (no ISO7816 APDUs) while an app is in the foreground (no background detection). Due out in the Fall, 2017... check the screenshot from WWDC keynote:

We have recently started looking into RFID solutions at my work place and we found a cheap solution for testing purposes.

One of the units from here:

http://www.sdid.com/products.shtml

Plugs into any windows mobile device with an SD slot and allows reading / writing. There is also a development kit to get you on your way with your own apps.

Hope this helps

I have used this code and it responds correctly, only the output value is nullable.

var packesCount = await botContext.Sales.Where(s => s.CustomerId == cust.CustomerId && s.Validated)
                                .SumAsync(s => (int?)s.PackesCount);
                            if(packesCount != null)
                            {
                                // your code
                            }
                            else
                            {
                                // your code
                            }

I think that you can bind the load event of the iframe, the event fires when the iframe content is fully loaded.

At the same time you can start a setTimeout, if the iFrame is loaded clear the timeout alternatively let the timeout fire.

Code:

var iframeError;

function change() {
    var url = $("#addr").val();
    $("#browse").attr("src", url);
    iframeError = setTimeout(error, 5000);
}

function load(e) {
    alert(e);
}

function error() {
    alert('error');
}

$(document).ready(function () {
    $('#browse').on('load', (function () {
        load('ok');
        clearTimeout(iframeError);
    }));

});

Demo: http://jsfiddle.net/IrvinDominin/QXc6P/

Second problem

It is because you miss the parens in the inline function call; try change this:

<iframe id="browse" style="width:100%;height:100%" onload="load" onerror="error"></iframe>

into this:

<iframe id="browse" style="width:100%;height:100%" onload="load('Done func');" onerror="error('failed function');"></iframe>

Since seangwright's solution (Edit 3) appears to be very useful, I also found it a pain to pack this feature into base component, and hint other project teammates to remember to call super() on ngOnDestroy to activate this feature.

This answer provide a way to set free from super call, and make "componentDestroyed$" a core of base component.

class BaseClass {
    protected componentDestroyed$: Subject<void> = new Subject<void>();
    constructor() {

        /// wrap the ngOnDestroy to be an Observable. and set free from calling super() on ngOnDestroy.
        let _$ = this.ngOnDestroy;
        this.ngOnDestroy = () => {
            this.componentDestroyed$.next();
            this.componentDestroyed$.complete();
            _$();
        }
    }

    /// placeholder of ngOnDestroy. no need to do super() call of extended class.
    ngOnDestroy() {}
}

And then you can use this feature freely for example:

@Component({
    selector: 'my-thing',
    templateUrl: './my-thing.component.html'
})
export class MyThingComponent extends BaseClass implements OnInit, OnDestroy {
    constructor(
        private myThingService: MyThingService,
    ) { super(); }

    ngOnInit() {
        this.myThingService.getThings()
            .takeUntil(this.componentDestroyed$)
            .subscribe(things => console.log(things));
    }

    /// optional. not a requirement to implement OnDestroy
    ngOnDestroy() {
        console.log('everything works as intended with or without super call');
    }

}

Below code will hide your text with fixed width you decide. but not quite right for responsive designs.

.CropLongTexts {
  width: 170px;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

Update

I have noticed in (mobile) device(s) that the text (mixed) with each other due to (fixed width)... so i have edited the code above to become hidden responsively as follow:

.CropLongTexts {
  max-width: 170px;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

The (max-width) ensure the text will be hidden responsively whatever the (screen size) and will not mixed with each other.

When you export your project as a 'Runnable jar' (Right mouse on project -> Export -> Runnable jar) you have the option to package all dependencies into the generated jar. It also has two other ways (see screenshot) to export your libraries, be aware of the licences when deciding which packaging method you will use.

The 'launch configuration' dropdown is populated with classes containing a main(String[]) method. The selected class is started when you 'run' the jar.

Exporting as a runnable jar uses the dependencies on your build path (Right mouse on project -> Build Path -> Configure Build Path...). When you export as a 'regular' (non-runnable) jar you can select any file in your project(s). If you have the libraries in your project folder you can include them but external dependencies, for example maven, cannot be included (for maven projects, search here).

For CentOS 7.8 & PHP 7.3

yum install rh-php73-php-mysqlnd

And then restart apache/php.

string dateInString = "01.10.2009";

DateTime startDate = DateTime.Parse(dateInString);
DateTime expiryDate = startDate.AddDays(30);
if (DateTime.Now > expiryDate) {
  //... trial expired
}

You can also use numpy.subtract

It has the advantage over the difference operator, -, that you do not have to transform the sequences (list or tuples) into a numpy arrays — you save the two commands:

array1 = np.array([1.1, 2.2, 3.3])
array2 = np.array([1, 2, 3])

Example: (Python 3.5)

import numpy as np
result = np.subtract([1.1, 2.2, 3.3], [1, 2, 3])
print ('the difference =', result)

which gives you

the difference = [ 0.1  0.2  0.3]

Remember, however, that if you try to subtract sequences (lists or tuples) with the - operator you will get an error. In this case, you need the above commands to transform the sequences in numpy arrays

Wrong Code:

print([1.1, 2.2, 3.3] - [1, 2, 3])

Compiler It converts the source code into the object code.

Linker It combines the multiple object files into a single executable program file.

Loader It loads the executable file into main memory.

1. git checkout my_other_branch
2. git add my_file my_other_file
3. git commit -m

And provide your commit message.

In short: Replace badge-important with either alert-danger or progress-bar-danger.

It looks like this: Bootply Demo.

You might combine the CSS class badge with alert-* or progess-bar-* to color them:

With class="badges alert-*"

  <span class="badge alert-info">badge</span> Info
  <span class="badge alert-success">badge</span> Success 
  <span class="badge alert-danger">badge</span> Danger   
  <span class="badge alert-warning">badge</span> Warning

Alerts Docu: http://getbootstrap.com/components/#alerts

With class="badges progress-bar-*" (as suggested by @clami219)

  <span class="badge progress-bar-info">badge</span> Info
  <span class="badge progress-bar-success">badge</span> Success
  <span class="badge progress-bar-danger">badge</span> Danger
  <span class="badge progress-bar-warning">badge</span> Warning

Using a cookie would probably be the best way to do this.

You could have a checkbox for 'Remember me?' and have the form create a cookie to store the //user's login// info. EDIT: User Session Information

To create a cookie, you'll need to process the login form with PHP.

I ran into the same problem.

I downloaded the 'popper.min.js' file from the CDN on the bootstrap website.

See here: https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js

Easier than compiling the project.

Important: You must include popper after jquery but BEFORE bootstrap.

If you are going to include specific path in most of the files in your application, create a Global variable to your root folder.

define("APPLICATION_PATH", realpath(dirname(__FILE__) . '/../app'));
or 
define("APPLICATION_PATH", realpath(DIR(__FILE__) . '/../app'));

Now this Global variable "APPLICATION_PATH" can be used to include all the files instead of calling realpath() everytime you include a new file.

EX:

include(APPLICATION_PATH ."/config/config.ini";

Hope it helps ;-)

There is a UDF that will do that described here:

User Defined Function to Strip HTML

CREATE FUNCTION [dbo].[udf_StripHTML] (@HTMLText VARCHAR(MAX))
RETURNS VARCHAR(MAX) AS
BEGIN
    DECLARE @Start INT
    DECLARE @End INT
    DECLARE @Length INT
    SET @Start = CHARINDEX('<',@HTMLText)
    SET @End = CHARINDEX('>',@HTMLText,CHARINDEX('<',@HTMLText))
    SET @Length = (@End - @Start) + 1
    WHILE @Start > 0 AND @End > 0 AND @Length > 0
    BEGIN
        SET @HTMLText = STUFF(@HTMLText,@Start,@Length,'')
        SET @Start = CHARINDEX('<',@HTMLText)
        SET @End = CHARINDEX('>',@HTMLText,CHARINDEX('<',@HTMLText))
        SET @Length = (@End - @Start) + 1
    END
    RETURN LTRIM(RTRIM(@HTMLText))
END
GO

Edit: note this is for SQL Server 2005, but if you change the keyword MAX to something like 4000, it will work in SQL Server 2000 as well.

For those looking for a one-liner:

grep xyz abc.txt | while read -r line; do echo "Processing $line"; done

Maybe you're looking for something like this:

def tableize(df):
    if not isinstance(df, pd.DataFrame):
        return
    df_columns = df.columns.tolist() 
    max_len_in_lst = lambda lst: len(sorted(lst, reverse=True, key=len)[0])
    align_center = lambda st, sz: "{0}{1}{0}".format(" "*(1+(sz-len(st))//2), st)[:sz] if len(st) < sz else st
    align_right = lambda st, sz: "{0}{1} ".format(" "*(sz-len(st)-1), st) if len(st) < sz else st
    max_col_len = max_len_in_lst(df_columns)
    max_val_len_for_col = dict([(col, max_len_in_lst(df.iloc[:,idx].astype('str'))) for idx, col in enumerate(df_columns)])
    col_sizes = dict([(col, 2 + max(max_val_len_for_col.get(col, 0), max_col_len)) for col in df_columns])
    build_hline = lambda row: '+'.join(['-' * col_sizes[col] for col in row]).join(['+', '+'])
    build_data = lambda row, align: "|".join([align(str(val), col_sizes[df_columns[idx]]) for idx, val in enumerate(row)]).join(['|', '|'])
    hline = build_hline(df_columns)
    out = [hline, build_data(df_columns, align_center), hline]
    for _, row in df.iterrows():
        out.append(build_data(row.tolist(), align_right))
    out.append(hline)
    return "\n".join(out)


df = pd.DataFrame([[1, 2, 3], [11111, 22, 333]], columns=['a', 'b', 'c'])
print tableize(df)

In my case it was related to vs-code running on my Linux machine. I ignored a warning which popped up about file watcher bla bla. The solution is on the vs-code docs page for linux https://code.visualstudio.com/docs/setup/linux#_visual-studio-code-is-unable-to-watch-for-file-changes-in-this-large-workspace-error-enospc

The solution is almost same (if not same) as the accepted answers, just has more explanation for anyone who gets here after running into the issues from vs-code.

The error is in this line: (% load pygmentize %}, an invalid tag. Change it to {% load pygmentize %}

pdfDoc.Open();
Paragraph para = new Paragraph("Hello World", new Font(Font.FontFamily.HELVETICA, 22));

That's the platform toolset for VS2015. You uninstalled it, therefore it is no longer available.

To change your Platform Toolset:

1. Right click your project, go to Properties.
2. Under Configuration Properties, go to General.
3. Change your Platform Toolset to one of the available ones.

Your CSS must be like this:

@media print {
   body {
      -webkit-print-color-adjust: exact;
   }
}

.vendorListHeading th {
   background-color: #1a4567 !important;
   color: white !important;   
}

Best solution for me, paste your class

@Override
public void onResume() {
    this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
    super.onResume();
}

@Override
public void onStart() {
    this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
    super.onStart();
}

I don't know if you can change the size at runtime but you can allocate the size at runtime. Try using this code:

class MyClass {
    void myFunction () {
        Scanner s = new Scanner (System.in);
        int myArray [];
        int x;

        System.out.print ("Enter the size of the array: ");
        x = s.nextInt();

        myArray = new int[x];
    }
}

this assigns your array size to be the one entered at run time into x.

Here is working solution:

Question:

Is it possible to change the thread principal to an user with no account on the local machine?

Answer:

Yes, you can change a thread principal even if the credentials you are using are not defined locally or are outside the "forest".

I just ran into this problem when trying to connect to an SQL server with NTLM authentication from a service. This call uses the credentials associated with the process meaning that you need either a local account or a domain account to authenticate before you can impersonate. Blah, blah...

But...

Calling LogonUser(..) with the attribute of ????_NEW_CREDENTIALS will return a security token without trying to authenticate the credentials. Kewl.. Don't have to define the account within the "forest". Once you have the token you might have to call DuplicateToken() with the option to enable impersonation resulting in a new token. Now call SetThreadToken( NULL, token ); (It might be &token?).. A call to ImpersonateLoggedonUser( token ); might be required, but I don't think so. Look it up..

Do what you need to do..

Call RevertToSelf() if you called ImpersonateLoggedonUser() then SetThreadToken( NULL, NULL ); (I think... look it up), and then CloseHandle() on the created handles..

No promises but this worked for me... This is off the top of my head (like my hair) and I can't spell!!!

Another pure Bash solution:

while IFS=':' read a b ; do
  echo "$a"
done < "$infile" > "$outfile"

Modern Solution

The result is that the circle never gets distorted and the text stays exactly in the middle of the circle - vertically and horizontally.

.circle {
  background: gold;
  width: 40px; 
  height: 40px;
  border-radius: 50%;
  display: flex; /* or inline-flex */
  align-items: center; 
  justify-content: center;
}

<div class="circle">text</div>

Simple and easy to use. Enjoy!

Even if its old question, for me in Eclipse I just right click on Src folder and properties (Alt+Enter) and the check for the Ignore optional compile problems removed the error.

doc.id gets the UID.

Combine with the rest of the data for one object like so:

Object.assign({ uid: doc.id }, doc.data())

My case was that i was using RDS (mysql db verion 8) of AWS and was connecting my application through EC2 (my php code 5.6 was in EC2).

Here in this case since it is RDS there is no my.cnf the parameters are maintained by PARAMETER Group of AWS. Refer: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_WorkingWithParamGroups.html

so what i did was:

1. Created a new Parameter group and then edited them.

2. Searched all character-set parameters. These are blank by default. edit them individually and select utf8 from drop down list.

character_set_client, character_set_connection, character_set_database, character_set_server

3. SAVE

And then most important, Rebooted RDS instance.

This has solved my problem and connection from php5.6 to mysql 8.x was working great.

hope this helps.

I have a scenario where I use the BannerViewController written by Apple to display my ads and a ScrollViewController embedded in the BannerViewController.

To prevent the navigation bar from hiding my content, I had to make two changes.

1) Modify BannerViewController.m

- (void)viewDidLoad
{
   [super viewDidLoad];
   float systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];
   if (systemVersion >= 7.0) {
      self.edgesForExtendedLayout = UIRectEdgeNone;
   }
}

2) Modify my ScrollViewContoller

- (void)viewDidLoad
{
    [super viewDidLoad];
    float systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];
    if (systemVersion >= 7.0) {
        self.edgesForExtendedLayout = UIRectEdgeBottom;
    }
}

Now the ads show up correctly at the bottom of the view instead of being covered by the Navigation bar and the content on the top is not cut off.

First we'll install @babel/cli, @babel/core and @babel/preset-env.

$ npm install --save-dev @babel/cli @babel/core @babel/preset-env

Then we'll create a .babelrc file for configuring babel.

$ touch .babelrc

This will host any options we might want to configure babel with.

{
  "presets": ["@babel/preset-env"]
}

With recent changes to babel, you will need to transpile your ES6 before node can run it.

So, we'll add our first script, build, in package.json.

"scripts": {
  "build": "babel index.js -d dist"
}

Then we'll add our start script in package.json.

"scripts": {
  "build": "babel index.js -d dist", // replace index.js with your filename
  "start": "npm run build && node dist/index.js"
}

Now let's start our server.

$ npm start

  Boolean condition=false;  //Instance variable declaration.

 //-----------------Inside oncreate--------------------------------------------------- 
  start =(Button)findViewById(R.id.id_start);
        start.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                starthandler();

                if(condition=true)
                {
                    condition=false;
                }


            }
        });

        stop=(Button) findViewById(R.id.id_stoplocatingsmartplug);

        stop.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                stophandler();

            }
        });


    }

//-----------------Inside oncreate---------------------------------------------------

 public void starthandler()
    {

        handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {


                if(!condition)
                {
                    //Do something after 100ms 


                }

            }
        }, 5000);

    }


    public void stophandler()
    {
        condition=true;
    }

I have written detailed tutorial covering current location here on demonuts.com.You can find more description here and also you can download whole demo source code for better understanding.

There are already many answers there but I want to show latest way to get location using Google API, so new programmers can use new method:

First of all, put this in gradle file

compile 'com.google.android.gms:play-services:8.4.0'

then implement necessary interfaces

public class MainActivity  extends BaseActivitiy implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, com.google.android.gms.location.LocationListener

declare instances

  private GoogleApiClient mGoogleApiClient;
  private Location mLocation;
  private LocationManager locationManager;
  private LocationRequest mLocationRequest;

put this in onCreate()

 mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

At last, override necessary methods

 @Override
    public void onConnected(Bundle bundle) {
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        mLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
        if(mLocation == null){
            startLocationUpdates();
        }
        if (mLocation != null) {
            double latitude = mLocation.getLatitude();
            double longitude = mLocation.getLongitude();
        } else {
            // Toast.makeText(this, "Location not Detected", Toast.LENGTH_SHORT).show();
        }
    }

    protected void startLocationUpdates() {
        // Create the location request
        mLocationRequest = LocationRequest.create()
                .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
                .setInterval(UPDATE_INTERVAL)
                .setFastestInterval(FASTEST_INTERVAL);
        // Request location updates
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient,
                mLocationRequest, this);
        Log.d("reque", "--->>>>");
    }

    @Override
    public void onConnectionSuspended(int i) {
        Log.i(TAG, "Connection Suspended");
        mGoogleApiClient.connect();
    }

    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {
        Log.i(TAG, "Connection failed. Error: " + connectionResult.getErrorCode());
    }

    @Override
    public void onStart() {
        super.onStart();
        mGoogleApiClient.connect();
    }

    @Override
    public void onStop() {
        super.onStop();
        if (mGoogleApiClient.isConnected()) {
            mGoogleApiClient.disconnect();
        }
    }
    @Override
    public void onLocationChanged(Location location) {

    }

Don't forget to start GPS in your device before running app.

API Documentation

According to the Android developers guide for android.hardware.Camera, they state:

We recommend using the new android.hardware.camera2 API for new applications.

On the information page about android.hardware.camera2, (linked above), it is stated:

The android.hardware.camera2 package provides an interface to individual camera devices connected to an Android device. It replaces the deprecated Camera class.

The problem

When you check that documentation you'll find that the implementation of these 2 Camera API's are very different.

For example getting camera orientation on android.hardware.camera

@Override
public int getOrientation(final int cameraId) {
    Camera.CameraInfo info = new Camera.CameraInfo();
    Camera.getCameraInfo(cameraId, info);
    return info.orientation;
}

Versus android.hardware.camera2

@Override
public int getOrientation(final int cameraId) {
    try {
        CameraManager manager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
        String[] cameraIds = manager.getCameraIdList();
        CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraIds[cameraId]);
        return characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);
    } catch (CameraAccessException e) {
        // TODO handle error properly or pass it on
        return 0;
    }
}

This makes it hard to switch from one to another and write code that can handle both implementations.

Note that in this single code example I already had to work around the fact that the olde camera API works with int primitives for camera IDs while the new one works with String objects. For this example I quickly fixed that by using the int as an index in the new API. If the camera's returned aren't always in the same order this will already cause issues. Alternative approach is to work with String objects and String representation of the old int cameraIDs which is probably safer.

One away around

Now to work around this huge difference you can implement an interface first and reference that interface in your code.

Here I'll list some code for that interface and the 2 implementations. You can limit the implementation to what you actually use of the camera API to limit the amount of work.

In the next section I'll quickly explain how to load one or another.

The interface wrapping all you need, to limit this example I only have 2 methods here.

public interface CameraSupport {
    CameraSupport open(int cameraId);
    int getOrientation(int cameraId);
}

Now have a class for the old camera hardware api:

@SuppressWarnings("deprecation")
public class CameraOld implements CameraSupport {

    private Camera camera;

    @Override
    public CameraSupport open(final int cameraId) {
        this.camera = Camera.open(cameraId);
        return this;
    }

    @Override
    public int getOrientation(final int cameraId) {
       Camera.CameraInfo info = new Camera.CameraInfo();
       Camera.getCameraInfo(cameraId, info);
       return info.orientation;
    }
}

And another one for the new hardware api:

public class CameraNew implements CameraSupport {

    private CameraDevice camera;
    private CameraManager manager;

    public CameraNew(final Context context) {
        this.manager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);
    }

    @Override
    public CameraSupport open(final int cameraId) {
        try {
            String[] cameraIds = manager.getCameraIdList();
            manager.openCamera(cameraIds[cameraId], new CameraDevice.StateCallback() {
                @Override
                public void onOpened(CameraDevice camera) {
                    CameraNew.this.camera = camera;
                }

                @Override
                public void onDisconnected(CameraDevice camera) {
                    CameraNew.this.camera = camera;
                    // TODO handle
                }

                @Override
                public void onError(CameraDevice camera, int error) {
                    CameraNew.this.camera = camera;
                    // TODO handle
                }
            }, null);
        } catch (Exception e) {
            // TODO handle
        }
        return this;
    }

    @Override
    public int getOrientation(final int cameraId) {
        try {
            String[] cameraIds = manager.getCameraIdList();
            CameraCharacteristics characteristics = manager.getCameraCharacteristics(cameraIds[cameraId]);
            return characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);
        } catch (CameraAccessException e) {
            // TODO handle
            return 0;
        }
    }
}

Loading the proper API

Now to load either your CameraOld or CameraNew class you'll have to check the API level since CameraNew is only available from api level 21.

If you have dependency injection set up already you can do so in your module when providing the CameraSupport implementation. Example:

@Module public class CameraModule {

    @Provides
    CameraSupport provideCameraSupport(){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            return new CameraNew(context);
        } else {
            return new CameraOld();
        }
    } 
}

If you don't use DI you can just make a utility or use Factory pattern to create the proper one. Important part is that the API level is checked.

I do not have experience with version 7 of JBoss but with 5 I often had issues when redeploying apps which went away when I cleaned the work and tmp folder. I wrote a script for that which was executed everytime the server shut down. Maybe executing it before startup is better considering abnormal shutdowns (which weren't uncommon with Jboss 5 :))

The linked list holds operations on the shared data structure.

For example, if I have a stack, it will be manipulated with pushes and pops. The linked list would be a set of pushes and pops on the pseudo-shared stack. Each thread sharing that stack will actually have a local copy, and to get to the current shared state, it'll walk the linked list of operations, and apply each operation in order to its local copy of the stack. When it reaches the end of the linked list, its local copy holds the current state (though, of course, it's subject to becoming stale at any time).

In the traditional model, you'd have some sort of locks around each push and pop. Each thread would wait to obtain a lock, then do a push or pop, then release the lock.

In this model, each thread has a local snapshot of the stack, which it keeps synchronized with other threads' view of the stack by applying the operations in the linked list. When it wants to manipulate the stack, it doesn't try to manipulate it directly at all. Instead, it simply adds its push or pop operation to the linked list, so all the other threads can/will see that operation and they can all stay in sync. Then, of course, it applies the operations in the linked list, and when (for example) there's a pop it checks which thread asked for the pop. It uses the popped item if and only if it's the thread that requested this particular pop.

Have a look at the example in this link :

http://docs.angularjs.org/api/ngSanitize.$sanitize

Basically, angular has a directive to insert html into pages. In your case you can insert the html using the ng-bind-html directive like so :

If you already have done all this :

// My magic HTML string function.
function htmlString (str) {
    return "<h1>" + str + "</h1>";
}

function Ctrl ($scope) {
  var str = "HELLO!";
  $scope.htmlString = htmlString(str);
}
Ctrl.$inject = ["$scope"];

Then in your html within the scope of that controller, you could

<div ng-bind-html="htmlString"></div>

Ctrl+C is what you need. If it didn't work, hit it harder. :-) Of course, you can also just close the shell window.

Edit: You didn't mention the circumstances. As a last resort, you could write a batch file that contains taskkill /im python.exe, and put it on your desktop, Start menu, etc. and run it when you need to kill a runaway script. Of course, it will kill all Python processes, so be careful.

Use conditional formatting (Home tab, styles section) and apply highlight cells rule (putting 0 in the Format cells that are equal to box) but select custom format then the Number tab. Select Category custom and in the type box put:

0;-0;;@

Sounds complicated but is actually simple.

This gives the advantage that the cell looks empty but 0 is still the underlying value, so any formulas you use against that cell/selection will still see it as being numeric and saves on lots of messing around with chained IF statements.

Partials can be used to make new derived functions that have some input parameters pre-assigned

To see some real world usage of partials, refer to this really good blog post:
http://chriskiehl.com/article/Cleaner-coding-through-partially-applied-functions/

A simple but neat beginner's example from the blog, covers how one might use partial on re.search to make code more readable. re.search method's signature is:

search(pattern, string, flags=0) 

By applying partial we can create multiple versions of the regular expression search to suit our requirements, so for example:

is_spaced_apart = partial(re.search, '[a-zA-Z]\s\=')
is_grouped_together = partial(re.search, '[a-zA-Z]\=')

Now is_spaced_apart and is_grouped_together are two new functions derived from re.search that have the pattern argument applied(since pattern is the first argument in the re.search method's signature).

The signature of these two new functions(callable) is:

is_spaced_apart(string, flags=0)     # pattern '[a-zA-Z]\s\=' applied
is_grouped_together(string, flags=0) # pattern '[a-zA-Z]\=' applied

This is how you could then use these partial functions on some text:

for text in lines:
    if is_grouped_together(text):
        some_action(text)
    elif is_spaced_apart(text):
        some_other_action(text)
    else:
        some_default_action()

You can refer the link above to get a more in depth understanding of the subject, as it covers this specific example and much more..

You can just create your own .white class and add it to the glyphicon element.

.white, .white a {
  color: #fff;
}

<i class="glyphicon glyphicon-home white"></i>

Heres a nicer way using closures

usort($your_data, function($a, $b)
{
    return strcmp($a->name, $b->name);
});

Please note this is not in PHP's documentation but if you using 5.3+ closures are supported where callable arguments can be provided.

How to auto increment by one, starting at 10 in MySQL:

create table foobar(
  id             INT PRIMARY KEY AUTO_INCREMENT,
  moobar         VARCHAR(500)
); 
ALTER TABLE foobar AUTO_INCREMENT=10;

INSERT INTO foobar(moobar) values ("abc");
INSERT INTO foobar(moobar) values ("def");
INSERT INTO foobar(moobar) values ("xyz");

select * from foobar;

'10', 'abc'
'11', 'def'
'12', 'xyz'

This auto increments the id column by one starting at 10.

Auto increment in MySQL by 5, starting at 10:

drop table foobar
create table foobar(
  id             INT PRIMARY KEY AUTO_INCREMENT,
  moobar         VARCHAR(500)
); 
SET @@auto_increment_increment=5;
ALTER TABLE foobar AUTO_INCREMENT=10;

INSERT INTO foobar(moobar) values ("abc");
INSERT INTO foobar(moobar) values ("def");
INSERT INTO foobar(moobar) values ("xyz");

select * from foobar;
'11', 'abc'
'16', 'def'
'21', 'xyz'

This auto increments the id column by 5 each time, starting at 10.

Tried all these methods for conversion ->

    public static void main(String[] args) {

    Object myObj = 10.101;
    System.out.println("Cast to Double: "+((Double)myObj)+10.99);   //concates

    Double d1 = new Double(myObj.toString());
    System.out.println("new Object String - Cast to Double: "+(d1+10.99));  //works

    double d3 = (double) myObj;
    System.out.println("new Object - Cast to Double: "+(d3+10.99));     //works

    double d4 = Double.valueOf((Double)myObj);
    System.out.println("Double.valueOf(): "+(d4+10.99));        //works

    double d5 = ((Number) myObj).doubleValue();
    System.out.println("Cast to Number and call doubleValue(): "+(d5+10.99));       //works

    double d2= Double.parseDouble((String) myObj);
    System.out.println("Cast to String to cast to Double: "+(d2+10));       //works
}

Just call window.location.href = new_url from your javascript and it will redirect the browser to that URL as it the user had typed that into the address bar

To see a visual diff of all differences between two branches I like to merge the two branches - WITHOUT committing the merge - and then use git gui or git Extensions to get an overview of the differences.

Git command line for merging without commiting:

git checkout branchA
git merge --no-commit --no-ff branchB

Then when done, you can undo the merge with

git merge --abort

(h/t to @jcugat's for the comment)

Or for what seems like rampant overkill, but is actually simplistic ... Pretty much covers all of your cases, and no empty string or unary concerns.

In the case the first arg is '-v', then do your conditional ps -ef, else in all other cases throw the usage.

#!/bin/sh
case $1 in
  '-v') if [ "$1" = -v ]; then
         echo "`ps -ef | grep -v '\['`"
        else
         echo "`ps -ef | grep '\[' | grep root`"
        fi;;
     *) echo "usage: $0 [-v]"
        exit 1;; #It is good practice to throw a code, hence allowing $? check
esac

If one cares not where the '-v' arg is, then simply drop the case inside a loop. The would allow walking all the args and finding '-v' anywhere (provided it exists). This means command line argument order is not important. Be forewarned, as presented, the variable arg_match is set, thus it is merely a flag. It allows for multiple occurrences of the '-v' arg. One could ignore all other occurrences of '-v' easy enough.

#!/bin/sh

usage ()
 {
  echo "usage: $0 [-v]"
  exit 1
 }

unset arg_match

for arg in $*
 do
  case $arg in
    '-v') if [ "$arg" = -v ]; then
           echo "`ps -ef | grep -v '\['`"
          else
           echo "`ps -ef | grep '\[' | grep root`"
          fi
          arg_match=1;; # this is set, but could increment.
       *) ;;
  esac
done

if [ ! $arg_match ]
 then
  usage
fi

But, allow multiple occurrences of an argument is convenient to use in situations such as:

$ adduser -u:sam -s -f -u:bob -trace -verbose

We care not about the order of the arguments, and even allow multiple -u arguments. Yes, it is a simple matter to also allow:

$ adduser -u sam -s -f -u bob -trace -verbose

In ASP.Net you can use System.Web.HttpUtility to safely encode the cookie value before writing to the cookie and convert it back to its original form on reading it out.

// Encode
HttpUtility.UrlEncode(cookieData);

// Decode
HttpUtility.UrlDecode(encodedCookieData);

This will stop ampersands and equals signs spliting a value into a bunch of name/value pairs as it is written to a cookie.

Servlet-mapping has two child tags, url-pattern and servlet-name. url-pattern specifies the type of urls for which, the servlet given in servlet-name should be called. Be aware that, the container will use case-sensitive for string comparisons for servlet matching.

First specification of url-pattern a web.xml file for the server context on the servlet container at server .com matches the pattern in <url-pattern>/status/*</url-pattern> as follows:

http://server.com/server/status/synopsis               = Matches
http://server.com/server/status/complete?date=today    = Matches
http://server.com/server/status                        = Matches
http://server.com/server/server1/status                = Does not match

Second specification of url-pattern A context located at the path /examples on the Agent at example.com matches the pattern in <url-pattern>*.map</url-pattern> as follows:

 http://server.com/server/US/Oregon/Portland.map    = Matches
 http://server.com/server/US/server/Seattle.map     = Matches
 http://server.com/server/Paris.France.map          = Matches
 http://server.com/server/US/Oregon/Portland.MAP    = Does not match, the extension is uppercase
 http://example.com/examples/interface/description/mail.mapi  =Does not match, the extension is mapi rather than map`

Third specification of url-mapping,A mapping that contains the pattern <url-pattern>/</url-pattern> matches a request if no other pattern matches. This is the default mapping. The servlet mapped to this pattern is called the default servlet.

The default mapping is often directed to the first page of an application. Explicitly providing a default mapping also ensures that malformed URL requests into the application return are handled by the application rather than returning an error.

The servlet-mapping element below maps the server servlet instance to the default mapping.

<servlet-mapping>
  <servlet-name>server</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

For the context that contains this element, any request that is not handled by another mapping is forwarded to the server servlet.

And Most importantly we should Know about Rule for URL path mapping

1. The container will try to find an exact match of the path of the request to the path of the servlet. A successful match selects the servlet.
2. The container will recursively try to match the longest path-prefix. This is done by stepping down the path tree a directory at a time, using the ’/’ character as a path separator. The longest match determines the servlet selected.
3. If the last segment in the URL path contains an extension (e.g. .jsp), the servlet container will try to match a servlet that handles requests for the extension. An extension is defined as the part of the last segment after the last ’.’ character.
4. If neither of the previous three rules result in a servlet match, the container will attempt to serve content appropriate for the resource requested. If a “default” servlet is defined for the application, it will be used.

Reference URL Pattern

The other answers above have answered your first question. As for your second question, how to detect an error of getting a value that is not set, I am not sure which of the following situation you mean:

1. Accessing an array element using an invalid index:
   If you use std::vector, you can use vector::at function instead of [] operator to get the value, if the index is invalid, an out_of_range exception will be thrown.

2. Accessing a valid index, but the element has not been set yet: As far as I know, there is no direct way of it. However, the following common practices can probably solve you problem: (1) Initializes all elements to a value that you are certain that is impossible to have. For example, if you are dealing with positive integers, set all elements to -1, so you know the value is not set yet when you find it being -1. (2). Simply use a bool array of the same size to indicate whether the element of the same index is set or not, this applies when all values are "possible".

[DataContract] and [DataMember] attribute are found in System.ServiceModel namespace which is in System.ServiceModel.dll .

System.ServiceModel uses the System and System.Runtime.Serialization namespaces to serialize the datamembers.

For Notepad++ 64-bit:

There is an unreleased 64-bit version of this plugin. You can download the DLL from here, drop it under Notepad++/plugins/NppTextFX directory and restart Notepad++. You will need to create the NppTextFX directory first though.

As per this GitHub issue, there might be some bugs lurking around. If you run into any, feel free to raise a GitHub ticket for each, as the author (HQJaTu) is recommending. As per the author, the code behind this binary is found on this branch.

Tested on Notepad++ v7.5.8 (64-bit, Build time: Jul 23 2018)

If you need a weak reference to the cell value:

object field = d.Rows[0][3]

or

object field = d.Rows[0].ItemArray[3]

Should do it

If you need a strongly typed reference (string in your case) you can use the DataRowExtensions.Field extension method:

string field = d.Rows[0].Field<string>(3);

(make sure System.Data is in listed in the namespaces in this case)

Indexes are 0 based so we first access the first row (0) and then the 4th column in this row (3)

1. Create Folder “resources” under Java Resources folder if your project doesn’t have it.
   2. create config.properties file with below value.

/Java Resources/resources/config.properties

for loading properties.

Properties prop = new Properties();
InputStream input = null;

try {

      input = getClass().getClassLoader().getResourceAsStream("config.properties");


    // load a properties file
    prop.load(input);

    // get the property value and print it out
    System.out.println(prop.getProperty("database"));
    System.out.println(prop.getProperty("dbuser"));
    System.out.println(prop.getProperty("dbpassword"));

} catch (IOException ex) {
    ex.printStackTrace();
} finally {
    if (input != null) {
        try {
            input.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

You say

I mean that it is not in use by any other application. If an application is using a port others can't use it until it becomes free.

But you can always connect to a port while others are using it if something's listening there. Otherwise, http port 80 would be a mess.

If your

   c = new TcpClient(ip, port);

fails, then nothing's listening there. Otherwise, it will connect, even if some other machine/application has a socket open to that ip and port.

I would recommend enforcing a strict format for phone numbers in the database. I use the following format. (Assuming US phone numbers)

Database: 5555555555x555

Display: (555) 555-5555 ext 555

Input: 10 digits or more digits embedded in any string. (Regex replacing removes all non-numeric characters)

This answer is about object creation with/without an explicit constructor since it is not covered in the other answers.

Consider the following class without an explicit constructor:

class Foo
{
public:
    Foo(int x) : m_x(x)
    {
    }

private:
    int m_x;
};

Objects of class Foo can be created in 2 ways:

Foo bar1(10);

Foo bar2 = 20;

Depending upon the implementation, the second manner of instantiating class Foo may be confusing, or not what the programmer intended. Prefixing the explicit keyword to the constructor would generate a compiler error at Foo bar2 = 20;.

It is usually good practice to declare single-argument constructors as explicit, unless your implementation specifically prohibits it.

Note also that constructors with

• default arguments for all parameters, or
• default arguments for the second parameter onwards

can both be used as single-argument constructors. So you may want to make these also explicit.

An example when you would deliberately not want to make your single-argument constructor explicit is if you're creating a functor (look at the 'add_x' struct declared in this answer). In such a case, creating an object as add_x add30 = 30; would probably make sense.

Here is a good write-up on explicit constructors.

There is a small difference between both.

Second declaration assignates the reference associated to the constant SOMEto the variable str

First declaration creates a new String having for value the value of the constant SOME and assignates its reference to the variable str.

In the first case, a second String has been created having the same value that SOME which implies more inititialization time. As a consequence, you should avoid it. Furthermore, at compile time, all constants SOMEare transformed into the same instance, which uses far less memory.

As a consequence, always prefer second syntax.

A simplest fix would be:

x = input("Give starting number: ")
y = input("Give ending number: ")

x = int(x)  # parse string into an integer
y = int(y)  # parse string into an integer

for i in range(x,y):
    print(i)

input returns you a string (raw_input in Python 2). int tries to parse it into an integer. This code will throw an exception if the string doesn't contain a valid integer string, so you'd probably want to refine it a bit using try/except statements.

If you're familiar with Ruby, its ||= seems akin to C#'s ?? to me. Here's some Ruby:

irb(main):001:0> str1 = nil
=> nil
irb(main):002:0> str1 ||= "new value"
=> "new value"
irb(main):003:0> str2 = "old value"
=> "old value"
irb(main):004:0> str2 ||= "another new value"
=> "old value"
irb(main):005:0> str1
=> "new value"
irb(main):006:0> str2
=> "old value"

And in C#:

string str1 = null;
str1 = str1 ?? "new value";
string str2 = "old value";
str2 = str2 ?? "another new value";

I found the answer to use double and triple quotation marks unsatisfactory. I used a nested DO...LOOP to write an ASP segment of code. There are repeated quotation marks within the string. When I ran the code:

thestring = "<asp:RectangleHotSpot Bottom=""" & bottom & """ HotSpotMode=""PostBack"" Left="""& left & """    PostBackValue=""" &xx & "." & yy & """ Right=""" & right & """ Top=""" & top & """/>"

the output was: <`asp:RectangleHotSpot Bottom="28

 'Changing the code to the explicit chr() call worked:

thestring = "<asp:RectangleHotSpot Bottom=""" & bottom & chr(34) & " HotSpotMode=""PostBack"" Left="""& left & chr(34) & " PostBackValue=""" &xx & "." & yy & chr(34) & " Right=""" & right & chr(34) & " Top=""" & top & chr(34) &"/>"

The output:

<asp:RectangleHotSpot Bottom="28" HotSpotMode="PostBack" Left="0" PostBackValue="0.0" Right="29" Top="0"/>

Here is code to get line number and column position

function getLineNumber(tArea) {

    return tArea.value.substr(0, tArea.selectionStart).split("\n").length;
}

function getCursorPos() {
    var me = $("textarea[name='documenttext']")[0];
    var el = $(me).get(0);
    var pos = 0;
    if ('selectionStart' in el) {
        pos = el.selectionStart;
    } else if ('selection' in document) {
        el.focus();
        var Sel = document.selection.createRange();
        var SelLength = document.selection.createRange().text.length;
        Sel.moveStart('character', -el.value.length);
        pos = Sel.text.length - SelLength;
    }
    var ret = pos - prevLine(me);
    alert(ret);

    return ret; 
}

function prevLine(me) {
    var lineArr = me.value.substr(0, me.selectionStart).split("\n");

    var numChars = 0;

    for (var i = 0; i < lineArr.length-1; i++) {
        numChars += lineArr[i].length+1;
    }

    return numChars;
}

tArea is the text area DOM element

<script type="text/javascript">
function report(func)
{
    func();
}

function daily()
{
    alert('daily');
}

function monthly()
{
    alert('monthly');
}
</script>

you can use:

First convert the value in a string to iterate it, Them each value can be convert to a Integer value = 12345

l = [ int(item) for item in str(value) ]

The modular crypt format for bcrypt consists of

• $2$, $2a$ or $2y$ identifying the hashing algorithm and format
• a two digit value denoting the cost parameter, followed by $
• a 53 characters long base-64-encoded value (they use the alphabet ., /, 0–9, A–Z, a–z that is different to the standard Base 64 Encoding alphabet) consisting of:
  • 22 characters of salt (effectively only 128 bits of the 132 decoded bits)
  • 31 characters of encrypted output (effectively only 184 bits of the 186 decoded bits)

Thus the total length is 59 or 60 bytes respectively.

As you use the 2a format, you’ll need 60 bytes. And thus for MySQL I’ll recommend to use the CHAR(60) BINARYor BINARY(60) (see The _bin and binary Collations for information about the difference).

CHAR is not binary safe and equality does not depend solely on the byte value but on the actual collation; in the worst case A is treated as equal to a. See The _bin and binary Collations for more information.

Instead of using the conditions syntax from Rails 2, use Rails 4's where method instead:

def self.search(search, page = 1 )
  wildcard_search = "%#{search}%"

  where("name ILIKE :search OR postal_code LIKE :search", search: wildcard_search)
    .page(page)
    .per_page(5)
end

NOTE: the above uses parameter syntax instead of ? placeholder: these both should generate the same sql.

def self.search(search, page = 1 )
  wildcard_search = "%#{search}%"

  where("name ILIKE ? OR postal_code LIKE ?", wildcard_search, wildcard_search)
    .page(page)
    .per_page(5)
end

NOTE: using ILIKE for the name - postgres case insensitive version of LIKE

Top Tip: making the change in my BIOS to enable virtualization and then using "restart" did not enable virtualization. Doing a cold boot (i.e. shutdown and restart) suddenly made it appear.

Not exactly making the cell a link, but the table itself. I use this as a button in e-mails, giving me div-like controls.

Regular expressions work pretty well for HTML scraping as well ;-) Though after looking at Beautiful Soup, I can see why this would be a valuable tool.

Very Simple way to create an object in Java using Class<?> with constructor argument(s) passing:

Case 1:- Here, is a small code in this Main class:

import java.lang.reflect.Constructor;
import java.lang.reflect.InvocationTargetException;

public class Main {

    public static void main(String args[]) throws ClassNotFoundException, NoSuchMethodException, SecurityException, InstantiationException, IllegalAccessException, IllegalArgumentException, InvocationTargetException {

        // Get class name as string.
        String myClassName = Base.class.getName();
        // Create class of type Base.
        Class<?> myClass = Class.forName(myClassName);
        // Create constructor call with argument types.
        Constructor<?> ctr = myClass.getConstructor(String.class);
        // Finally create object of type Base and pass data to constructor.
        String arg1 = "My User Data";
        Object object = ctr.newInstance(new Object[] { arg1 });
        // Type-cast and access the data from class Base.
        Base base = (Base)object;
        System.out.println(base.data);
    }

}

And, here is the Base class structure:

public class Base {

    public String data = null;

    public Base() 
    {
        data = "default";
        System.out.println("Base()");
    }

    public Base(String arg1) {
        data = arg1;
        System.out.println("Base("+arg1+")");
    }

}

Case 2:- You, can code similarly for constructor with multiple argument and copy constructor. For example, passing 3 arguments as parameter to the Base constructor will need the constructor to be created in class and a code change in above as:

Constructor<?> ctr = myClass.getConstructor(String.class, String.class, String.class);
Object object = ctr.newInstance(new Object[] { "Arg1", "Arg2", "Arg3" }); 

And here the Base class should somehow look like:

public class Base {

    public Base(String a, String b, String c){
        // This constructor need to be created in this case.
    }   
}

Note:- Don't forget to handle the various exceptions which need to be handled in the code.

I had to do this:

npx tsc app.ts

You can also try closing other programs. :)

It's pretty simple, but worked for me. In my case the VM just don't had enough memory to run, and i got the same message. So i had to clean up the ram, by closing unnecessary programs.

You need to get the HttpRequestMessage from the current OperationContext. Using OperationContext you can do it like so

OperationContext context = OperationContext.Current;
MessageProperties messageProperties = context.IncomingMessageProperties;

HttpRequestMessageProperty requestProperty = messageProperties[HttpRequestMessageProperty.Name] as HttpRequestMessageProperty;

string customHeaderValue = requestProperty.Headers["Custom"];

the main method should be declared in the your class like this :

public class derivativeQuiz_source{
    // bunch of methods .....

    public static void main(String args[])
    {
        // code 
    }
}

I found that none of the answers here applied to my specific use case, so I thought I would share my solution.

I was looking to redirect an unauthentciated user to public version of an app page with any possible URL params. Example:

/app/4903294/my-great-car?email=coolguy%40gmail.com to

/public/4903294/my-great-car?email=coolguy%40gmail.com

Here's the solution that worked for me.

return redirect(url_for('app.vehicle', vid=vid, year_make_model=year_make_model, **request.args))

Hope this helps someone!

If you are using ArrayAdapter or BaseAdapter to populate the list items. Override the isEnabled method and return false.

 @Override
  public boolean isEnabled (int position) {
    return false;
  }

<a href="javascript:history.back(1)">Back</a>

this one (by Eiko) is perfect, use css to make a button of <a>... eg you can use this css class in <a> as `

<a class=".back_button" href="javascript:history.back(1)">Back</a>`

.back_button {
display:block;

PowerShell has really wacky return semantics - at least when viewed from a more traditional programming perspective. There are two main ideas to wrap your head around:

• All output is captured, and returned
• The return keyword really just indicates a logical exit point

Thus, the following two script blocks will do effectively the exact same thing:

$a = "Hello, World"
return $a

$a = "Hello, World"
$a
return

The $a variable in the second example is left as output on the pipeline and, as mentioned, all output is returned. In fact, in the second example you could omit the return entirely and you would get the same behavior (the return would be implied as the function naturally completes and exits).

Without more of your function definition I can't say why you are getting a PSMethod object. My guess is that you probably have something a few lines up that is not being captured and is being placed on the output pipeline.

It is also worth noting that you probably don't need those semicolons - unless you are nesting multiple expressions on a single line.

You can read more about the return semantics on the about_Return page on TechNet, or by invoking the help return command from PowerShell itself.

Following solution is working fine.

With Spring boot , the spring.config.location does work,just provide comma separated properties files.

see the below code

@PropertySource(ignoreResourceNotFound=true,value="classpath:jdbc-${spring.profiles.active}.properties")
public class DBConfig{

     @Value("${jdbc.host}")
        private String jdbcHostName;
     }
}

one can put the default version of jdbc.properties inside application. The external versions can be set lie this.

java -jar target/myapp.jar --spring.config.location=classpath:file:///C:/Apps/springtest/jdbc.properties,classpath:file:///C:/Apps/springtest/jdbc-dev.properties

Based on profile value set using spring.profiles.active property, the value of jdbc.host will be picked up. So when (on windows)

set spring.profiles.active=dev

jdbc.host will take value from jdbc-dev.properties.

for

set spring.profiles.active=default

jdbc.host will take value from jdbc.properties.

According to the w3 spec section 4.6.3 for XMLHttpRequest a user agent should honor the Set-Cookie header. So the answer is yes you should be able to.

If the user agent supports HTTP State Management it should persist, discard and send cookies (as received in the Set-Cookie response header, and sent in the Cookie header) as applicable.

If the memory of the Mat mat is continuous (all its data is continuous), you can directly get its data to a 1D array:

std::vector<uchar> array(mat.rows*mat.cols*mat.channels());
if (mat.isContinuous())
    array = mat.data;

Otherwise, you have to get its data row by row, e.g. to a 2D array:

uchar **array = new uchar*[mat.rows];
for (int i=0; i<mat.rows; ++i)
    array[i] = new uchar[mat.cols*mat.channels()];

for (int i=0; i<mat.rows; ++i)
    array[i] = mat.ptr<uchar>(i);

UPDATE: It will be easier if you're using std::vector, where you can do like this:

std::vector<uchar> array;
if (mat.isContinuous()) {
  // array.assign(mat.datastart, mat.dataend); // <- has problems for sub-matrix like mat = big_mat.row(i)
  array.assign(mat.data, mat.data + mat.total()*mat.channels());
} else {
  for (int i = 0; i < mat.rows; ++i) {
    array.insert(array.end(), mat.ptr<uchar>(i), mat.ptr<uchar>(i)+mat.cols*mat.channels());
  }
}

p.s.: For cv::Mats of other types, like CV_32F, you should do like this:

std::vector<float> array;
if (mat.isContinuous()) {
  // array.assign((float*)mat.datastart, (float*)mat.dataend); // <- has problems for sub-matrix like mat = big_mat.row(i)
  array.assign((float*)mat.data, (float*)mat.data + mat.total()*mat.channels());
} else {
  for (int i = 0; i < mat.rows; ++i) {
    array.insert(array.end(), mat.ptr<float>(i), mat.ptr<float>(i)+mat.cols*mat.channels());
  }
}

UPDATE2: For OpenCV Mat data continuity, it can be summarized as follows:

• Matrices created by imread(), clone(), or a constructor will always be continuous.
• The only time a matrix will not be continuous is when it borrows data (except the data borrowed is continuous in the big matrix, e.g. 1. single row; 2. multiple rows with full original width) from an existing matrix (i.e. created out of an ROI of a big mat).

When the user presses the tab button the user will be taken through the form in the order 1, 2, and 3 as indicated in the example below.

Email: <input name="email" tabindex="2"  />

When using sp_rename which works like in above answers, check also which objects are affected after renaming, that reference that table, because you need to change those too

I took a code example for table dependencies at Pinal Dave's blog here

USE AdventureWorks
GO
SELECT
referencing_schema_name = SCHEMA_NAME(o.SCHEMA_ID),
referencing_object_name = o.name,
referencing_object_type_desc = o.type_desc,
referenced_schema_name,
referenced_object_name = referenced_entity_name,
referenced_object_type_desc = o1.type_desc,
referenced_server_name, referenced_database_name
--,sed.* -- Uncomment for all the columns
FROM
sys.sql_expression_dependencies sed
INNER JOIN
sys.objects o ON sed.referencing_id = o.[object_id]
LEFT OUTER JOIN
sys.objects o1 ON sed.referenced_id = o1.[object_id]
WHERE
referenced_entity_name = 'Customer'

So, all these dependent objects needs to be updated also

Or use some add-in if you can, some of them have feature to rename object, and all depend,ent objects too

That's the screenshot of the answer for your question.

I realise this is an old question but for anyone who does come across it this can be done using contenteditable as shown in this JSFiddle.

Kudos to Alex who mentioned this in the comments (I didn't see that until now!)

Here's a solution to the general case that doesn't involve needing to know the length of the array ahead of time, using collect, or using udfs. Unfortunately this only works for spark version 2.1 and above, because it requires the posexplode function.

Suppose you had the following DataFrame:

df = spark.createDataFrame(
    [
        [1, 'A, B, C, D'], 
        [2, 'E, F, G'], 
        [3, 'H, I'], 
        [4, 'J']
    ]
    , ["num", "letters"]
)
df.show()
#+---+----------+
#|num|   letters|
#+---+----------+
#|  1|A, B, C, D|
#|  2|   E, F, G|
#|  3|      H, I|
#|  4|         J|
#+---+----------+

Split the letters column and then use posexplode to explode the resultant array along with the position in the array. Next use pyspark.sql.functions.expr to grab the element at index pos in this array.

import pyspark.sql.functions as f

df.select(
        "num",
        f.split("letters", ", ").alias("letters"),
        f.posexplode(f.split("letters", ", ")).alias("pos", "val")
    )\
    .show()
#+---+------------+---+---+
#|num|     letters|pos|val|
#+---+------------+---+---+
#|  1|[A, B, C, D]|  0|  A|
#|  1|[A, B, C, D]|  1|  B|
#|  1|[A, B, C, D]|  2|  C|
#|  1|[A, B, C, D]|  3|  D|
#|  2|   [E, F, G]|  0|  E|
#|  2|   [E, F, G]|  1|  F|
#|  2|   [E, F, G]|  2|  G|
#|  3|      [H, I]|  0|  H|
#|  3|      [H, I]|  1|  I|
#|  4|         [J]|  0|  J|
#+---+------------+---+---+

Now we create two new columns from this result. First one is the name of our new column, which will be a concatenation of letter and the index in the array. The second column will be the value at the corresponding index in the array. We get the latter by exploiting the functionality of pyspark.sql.functions.expr which allows us use column values as parameters.

df.select(
        "num",
        f.split("letters", ", ").alias("letters"),
        f.posexplode(f.split("letters", ", ")).alias("pos", "val")
    )\
    .drop("val")\
    .select(
        "num",
        f.concat(f.lit("letter"),f.col("pos").cast("string")).alias("name"),
        f.expr("letters[pos]").alias("val")
    )\
    .show()
#+---+-------+---+
#|num|   name|val|
#+---+-------+---+
#|  1|letter0|  A|
#|  1|letter1|  B|
#|  1|letter2|  C|
#|  1|letter3|  D|
#|  2|letter0|  E|
#|  2|letter1|  F|
#|  2|letter2|  G|
#|  3|letter0|  H|
#|  3|letter1|  I|
#|  4|letter0|  J|
#+---+-------+---+

Now we can just groupBy the num and pivot the DataFrame. Putting that all together, we get:

df.select(
        "num",
        f.split("letters", ", ").alias("letters"),
        f.posexplode(f.split("letters", ", ")).alias("pos", "val")
    )\
    .drop("val")\
    .select(
        "num",
        f.concat(f.lit("letter"),f.col("pos").cast("string")).alias("name"),
        f.expr("letters[pos]").alias("val")
    )\
    .groupBy("num").pivot("name").agg(f.first("val"))\
    .show()
#+---+-------+-------+-------+-------+
#|num|letter0|letter1|letter2|letter3|
#+---+-------+-------+-------+-------+
#|  1|      A|      B|      C|      D|
#|  3|      H|      I|   null|   null|
#|  2|      E|      F|      G|   null|
#|  4|      J|   null|   null|   null|
#+---+-------+-------+-------+-------+

All tables within the bootstrap stretch according to their container, which you can easily do by placing your table inside a .span* grid element of your choice. If you wish to remove this property you can create your own table class and simply add it to the table you want to expand with the content within:

.table-nonfluid {
   width: auto !important;
}

You can add this class inside your own stylesheet and simply add it to the container of your table like so:

<table class="table table-nonfluid"> ... </table>

This way your change won't affect the bootstrap stylesheet itself (you might want to have a fluid table somewhere else in your document).

This example does not swap two int pointers. It swaps the value of the integers that pa and pb are pointing to. Here's an example of what's going on when you call this:

void Swap1 (int *pa, int *pb){
    int temp = *pa;
    *pa = *pb;
    *pb = temp;
}

int main()
{
    int a = 42;
    int b = 17;


    int *pa = &a;
    int *pb = &b;

    printf("--------Swap1---------\n");
    printf("a = %d\n b = %d\n", a, b);
    swap1(pa, pb);
    printf("a = %d\n = %d\n", a, a);
    printf("pb address =  %p\n", pa);
    printf("pa address =  %p\n", pb);
}

The output here is:

a = 42
b = 17
pa address =  0x7fffdf933228
pb address =  0x7fffdf93322c
--------Swap---------
pa = 17
pb = 42
a = 17
b = 42
pa address =  0x7fffdf933228
pb address =  0x7fffdf93322c

Note that the values swapped, but the pointer's addresses did not swap!

In order to swap addresses we need to do this:

void swap2 (int **pa, int **pb){
    int temp = *pa;
    *pa = *pb;
    *pb = temp;
}

and in main call the function like swap2(&pa, &pb);

Now the addresses are swapped, as well as the values for the pointers. a and b have the same values that the are initialized with The integers a and b did not swap because it swap2 swaps the addresses being being pointed to by the pointers!:

a = 42
b = 17
pa address =  0x7fffddaa9c98
pb address =  0x7fffddaa9c9c
--------Swap---------
pa = 17
pb = 42
a = 42
b = 17
pa address =  0x7fffddaa9c9c
pb address =  0x7fffddaa9c98

Since Strings in C are char pointers, and you want to swap Strings, you are really swapping a char pointer. As in the examples with an int, you need a double pointer to swap addresses.

The values of integers can be swapped even if the address isn't, but Strings are by definition a character pointer. You could swap one char with single pointers as the parameter, but a character pointer needs to be a double pointer in order to swap the strings.

I had two controllers with the same name defined in two different javascript files. Irritating that angular can't give a clearer error message indicating a namespace conflict.

I think you've missed the point of access control.

A quick recap on why CORS exists: Since JS code from a website can execute XHR, that site could potentially send requests to other sites, masquerading as you and exploiting the trust those sites have in you(e.g. if you have logged in, a malicious site could attempt to extract information or execute actions you never wanted) - this is called a CSRF attack. To prevent that, web browsers have very stringent limitations on what XHR you can send - you are generally limited to just your domain, and so on.

Now, sometimes it's useful for a site to allow other sites to contact it - sites that provide APIs or services, like the one you're trying to access, would be prime candidates. CORS was developed to allow site A(e.g. paste.ee) to say "I trust site B, so you can send XHR from it to me". This is specified by site A sending "Access-Control-Allow-Origin" headers in its responses.

In your specific case, it seems that paste.ee doesn't bother to use CORS. Your best bet is to contact the site owner and find out why, if you want to use paste.ee with a browser script. Alternatively, you could try using an extension(those should have higher XHR privileges).

What kind of document library information do you want in the view? How do you want the user to filter the view?

In general the most powerful way of creating views in sharepoint is with the data view web part. http://office.microsoft.com/en-us/sharepointdesigner/HA100948041033.aspx

You will need Microsoft Office SharePoint Designer.

You can present different views of you folders using the data view filter and sorting controls.

You can use web part connections to filter a dataview. You can use any datasource linked to say a drop down to filter a dataview. How to tie a dropdown list to a gridview in Sharepoint 2007?

Fedora, did it via iptables

sudo iptables -I INPUT -p tcp --dport 3030 -j ACCEPT
sudo service iptables save

Seems to work

You could convert your integer into a string. As the minus sign will not match the digits, you will have no negative years.

Another solution to the problem could be the following set of CSS rules:

.ellipsis{
 white-space:nowrap;
 overflow:hidden;
}

.ellipsis:after{
  content:'...';
}

The only drawback with the above CSS is that it would add the "..." irrespective of whether the text-overflows the container or not. Still, if you have a case where you have a bunch of elements and are sure that content will overflow, this one would be a simpler set of rules.

My two cents. Hats off to the original technique by Justin Maxwell

The div element has its own alignment attribute, align.

<div align="center">

/etc/services is only advisory, it's a listing of well-known ports. It doesn't mean that anything is actually running on that port or that the named service will run on that port.

In PostgreSQL's case it's typical to use port 5432 if it is available. If it isn't, most installers will choose the next free port, usually 5433.

You can see what is actually running using the netstat tool (available on OS X, Windows, and Linux, with command line syntax varying across all three).

This is further complicated on Mac OS X systems by the horrible mess of different PostgreSQL packages - Apple's ancient version of PostgreSQL built in to the OS, Postgres.app, Homebrew, Macports, the EnterpriseDB installer, etc etc.

What ends up happening is that the user installs Pg and starts a server from one packaging, but uses the psql and libpq client from a different packaging. Typically this occurs when they're running Postgres.app or homebrew Pg and connecting with the psql that shipped with the OS. Not only do these sometimes have different default ports, but the Pg that shipped with Mac OS X has a different default unix socket path, so even if the server is running on the same port it won't be listening to the same unix socket.

Most Mac users work around this by just using tcp/ip with psql -h localhost. You can also specify a port if required, eg psql -h localhost -p 5433. You might have multiple PostgreSQL instances running so make sure you're connecting to the right one by using select version() and SHOW data_directory;.

You can also specify a unix socket directory; check the unix_socket_directories setting of the PostgreSQL instance you wish to connect to and specify that with psql -h, e.g.psql -h /tmp.

A cleaner solution is to correct your system PATH so that the psql and libpq associated with the PostgreSQL you are actually running is what's found first on the PATH. The details of that depend on your Mac OS X version and which Pg packages you have installed. I don't use Mac and can't offer much more detail on that side without spending more time than is currently available.

JSON is the JavaScript Object Notation. There is no such thing as a JSON object. JSON is just a way of representing a JavaScript object in text.

So what you're after is a way of updating a in in-memory JavaScript object. qiao's answer shows how to do that simply enough.

I'd suggest try the change event? test to see if it has a value if it does then you can continue with your code. jQuery has

.bind("change", function(){ ... });

Or

.change(function(){ ... }); 

which are equivalents.

http://api.jquery.com/change/

for a unique selector change your name attribute to id and then jQuery("#imafile") or a general jQuery('input[type="file"]') for all the file inputs

If you are using ES6 you can:

var sample = [1, 2, 3]

var result = sample.filter(elem => elem !== 2)

/* output */
[1, 3]

Also take notice filter does not update the existing array it will return a new filtered array every time.

On Debian WSL (Windows Subsystem for Linux) I had to use:

sudo chmod -R 775 /var/log/nginx

For the folder name and drive, you can use:

echo %~dp0

You can get a lot more information using different modifiers:

%~I         - expands %I removing any surrounding quotes (")
%~fI        - expands %I to a fully qualified path name
%~dI        - expands %I to a drive letter only
%~pI        - expands %I to a path only
%~nI        - expands %I to a file name only
%~xI        - expands %I to a file extension only
%~sI        - expanded path contains short names only
%~aI        - expands %I to file attributes of file
%~tI        - expands %I to date/time of file
%~zI        - expands %I to size of file

The modifiers can be combined to get compound results:
%~dpI       - expands %I to a drive letter and path only
%~nxI       - expands %I to a file name and extension only
%~fsI       - expands %I to a full path name with short names only

This is a copy paste from the "for /?" command on the prompt. Hope it helps.

The node-mysql library automatically performs escaping when used as you are already doing. See https://github.com/felixge/node-mysql#escaping-query-values

You just need to declare a as a global in thread2, so that you aren't modifying an a that is local to that function.

def thread2(threadname):
    global a
    while True:
        a += 1
        time.sleep(1)

In thread1, you don't need to do anything special, as long as you don't try to modify the value of a (which would create a local variable that shadows the global one; use global a if you need to)>

def thread1(threadname):
    #global a       # Optional if you treat a as read-only
    while a < 10:
        print a

You may have spaces or tabs in your "empty" line. Use POSIX classes with sed to remove all lines containing only whitespace:

sed '/^[[:space:]]*$/d'

A shorter version that uses ERE, for example with gnu sed:

sed -r '/^\s*$/d'

(Note that sed does NOT support PCRE.)

There's actually an easier way than exporting and unsetting or sourcing again (at least in bash, as long as you're ok with passing the environment variables manually):

let a.sh be

#!/bin/bash
secret="winkle my tinkle"
echo Yo, lemme tell you \"$secret\", b.sh!
Message=$secret ./b.sh

and b.sh be

#!/bin/bash
echo I heard \"$Message\", yo

Observed output is

[rob@Archie test]$ ./a.sh
Yo, lemme tell you "winkle my tinkle", b.sh!
I heard "winkle my tinkle", yo

The magic lies in the last line of a.sh, where Message, for only the duration of the invocation of ./b.sh, is set to the value of secret from a.sh. Basically, it's a little like named parameters/arguments. More than that, though, it even works for variables like $DISPLAY, which controls which X Server an application starts in.

Remember, the length of the list of environment variables is not infinite. On my system with a relatively vanilla kernel, xargs --show-limits tells me the maximum size of the arguments buffer is 2094486 bytes. Theoretically, you're using shell scripts wrong if your data is any larger than that (pipes, anyone?)

You can create an extension for UIView to access these values in the design editor

extension UIView{

    @IBInspectable var shadowOffset: CGSize{
        get{
            return self.layer.shadowOffset
        }
        set{
            self.layer.shadowOffset = newValue
        }
    }

    @IBInspectable var shadowColor: UIColor{
        get{
            return UIColor(cgColor: self.layer.shadowColor!)
        }
        set{
            self.layer.shadowColor = newValue.cgColor
        }
    }

    @IBInspectable var shadowRadius: CGFloat{
        get{
            return self.layer.shadowRadius
        }
        set{
            self.layer.shadowRadius = newValue
        }
    }

    @IBInspectable var shadowOpacity: Float{
        get{
            return self.layer.shadowOpacity
        }
        set{
            self.layer.shadowOpacity = newValue
        }
    }
}

This is because you define your "doc" variable outside of your click event. The first time you click the button the doc variable contains a new jsPDF object. But when you click for a second time, this variable can't be used in the same way anymore. As it is already defined and used the previous time.

change it to:

$(function () {

    var specialElementHandlers = {
        '#editor': function (element,renderer) {
            return true;
        }
    };
 $('#cmd').click(function () {
        var doc = new jsPDF();
        doc.fromHTML(
            $('#target').html(), 15, 15, 
            { 'width': 170, 'elementHandlers': specialElementHandlers }, 
            function(){ doc.save('sample-file.pdf'); }
        );

    });  
});

and it will work.

I have done this way:

Get Compressed Bitmap from Singleton class:

ImageView imageView = (ImageView)findViewById(R.id.imageView);
Bitmap bitmap = ImageUtils.getInstant().getCompressedBitmap("Your_Image_Path_Here");
imageView.setImageBitmap(bitmap);

ImageUtils.java:

public class ImageUtils {

    public static ImageUtils mInstant;

    public static ImageUtils getInstant(){
        if(mInstant==null){
            mInstant = new ImageUtils();
        }
        return mInstant;
    }

    public  Bitmap getCompressedBitmap(String imagePath) {
        float maxHeight = 1920.0f;
        float maxWidth = 1080.0f;
        Bitmap scaledBitmap = null;
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        Bitmap bmp = BitmapFactory.decodeFile(imagePath, options);

        int actualHeight = options.outHeight;
        int actualWidth = options.outWidth;
        float imgRatio = (float) actualWidth / (float) actualHeight;
        float maxRatio = maxWidth / maxHeight;

        if (actualHeight > maxHeight || actualWidth > maxWidth) {
            if (imgRatio < maxRatio) {
                imgRatio = maxHeight / actualHeight;
                actualWidth = (int) (imgRatio * actualWidth);
                actualHeight = (int) maxHeight;
            } else if (imgRatio > maxRatio) {
                imgRatio = maxWidth / actualWidth;
                actualHeight = (int) (imgRatio * actualHeight);
                actualWidth = (int) maxWidth;
            } else {
                actualHeight = (int) maxHeight;
                actualWidth = (int) maxWidth;

            }
        }

        options.inSampleSize = calculateInSampleSize(options, actualWidth, actualHeight);
        options.inJustDecodeBounds = false;
        options.inDither = false;
        options.inPurgeable = true;
        options.inInputShareable = true;
        options.inTempStorage = new byte[16 * 1024];

        try {
            bmp = BitmapFactory.decodeFile(imagePath, options);
        } catch (OutOfMemoryError exception) {
            exception.printStackTrace();

        }
        try {
            scaledBitmap = Bitmap.createBitmap(actualWidth, actualHeight, Bitmap.Config.ARGB_8888);
        } catch (OutOfMemoryError exception) {
            exception.printStackTrace();
        }

        float ratioX = actualWidth / (float) options.outWidth;
        float ratioY = actualHeight / (float) options.outHeight;
        float middleX = actualWidth / 2.0f;
        float middleY = actualHeight / 2.0f;

        Matrix scaleMatrix = new Matrix();
        scaleMatrix.setScale(ratioX, ratioY, middleX, middleY);

        Canvas canvas = new Canvas(scaledBitmap);
        canvas.setMatrix(scaleMatrix);
        canvas.drawBitmap(bmp, middleX - bmp.getWidth() / 2, middleY - bmp.getHeight() / 2, new Paint(Paint.FILTER_BITMAP_FLAG));

        ExifInterface exif = null;
        try {
            exif = new ExifInterface(imagePath);
            int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 0);
            Matrix matrix = new Matrix();
            if (orientation == 6) {
                matrix.postRotate(90);
            } else if (orientation == 3) {
                matrix.postRotate(180);
            } else if (orientation == 8) {
                matrix.postRotate(270);
            }
            scaledBitmap = Bitmap.createBitmap(scaledBitmap, 0, 0, scaledBitmap.getWidth(), scaledBitmap.getHeight(), matrix, true);
        } catch (IOException e) {
            e.printStackTrace();
        }
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        scaledBitmap.compress(Bitmap.CompressFormat.JPEG, 85, out);

        byte[] byteArray = out.toByteArray();

        Bitmap updatedBitmap = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);

        return updatedBitmap;
    }

    private int calculateInSampleSize(BitmapFactory.Options options, int reqWidth, int reqHeight) {
        final int height = options.outHeight;
        final int width = options.outWidth;
        int inSampleSize = 1;

        if (height > reqHeight || width > reqWidth) {
            final int heightRatio = Math.round((float) height / (float) reqHeight);
            final int widthRatio = Math.round((float) width / (float) reqWidth);
            inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;
        }
        final float totalPixels = width * height;
        final float totalReqPixelsCap = reqWidth * reqHeight * 2;

        while (totalPixels / (inSampleSize * inSampleSize) > totalReqPixelsCap) {
            inSampleSize++;
        }
        return inSampleSize;
    }
}

Dimensions are same after compressing Bitmap.

How did I checked ?

Bitmap beforeBitmap = BitmapFactory.decodeFile("Your_Image_Path_Here");
Log.i("Before Compress Dimension", beforeBitmap.getWidth()+"-"+beforeBitmap.getHeight());

Bitmap afterBitmap = ImageUtils.getInstant().getCompressedBitmap("Your_Image_Path_Here");
Log.i("After Compress Dimension", afterBitmap.getWidth() + "-" + afterBitmap.getHeight());

Output:

Before Compress : Dimension: 1080-1452
After Compress : Dimension: 1080-1452

Hope this will help you.

Here is a guide by @CTS_AE on how to use NPM with standalone node.exe: https://stackoverflow.com/a/31148216/228508

1. Download the node.exe stand-alone from nodejs.org
2. Grab an NPM release zip off of github https://github.com/npm/npm/releases
3. Create a folder named: node_modules in the same folder as node.exe
4. Extract the NPM zip into the node_modules folder
5. Rename the extracted npm folder to npm and remove any versioning ie: npm-3.3.4 –> npm.
6. Copy npm.cmd out of the /npm/bin/ folder into the root folder with node.exe

You can’t use \s in Java to match white space on its own native character set, because Java doesn’t support the Unicode white space property — even though doing so is strictly required to meet UTS#18’s RL1.2! What it does have is not standards-conforming, alas.

Unicode defines 26 code points as \p{White_Space}: 20 of them are various sorts of \pZ GeneralCategory=Separator, and the remaining 6 are \p{Cc} GeneralCategory=Control.

White space is a pretty stable property, and those same ones have been around virtually forever. Even so, Java has no property that conforms to The Unicode Standard for these, so you instead have to use code like this:

String whitespace_chars =  ""       /* dummy empty string for homogeneity */
                        + "\\u0009" // CHARACTER TABULATION
                        + "\\u000A" // LINE FEED (LF)
                        + "\\u000B" // LINE TABULATION
                        + "\\u000C" // FORM FEED (FF)
                        + "\\u000D" // CARRIAGE RETURN (CR)
                        + "\\u0020" // SPACE
                        + "\\u0085" // NEXT LINE (NEL) 
                        + "\\u00A0" // NO-BREAK SPACE
                        + "\\u1680" // OGHAM SPACE MARK
                        + "\\u180E" // MONGOLIAN VOWEL SEPARATOR
                        + "\\u2000" // EN QUAD 
                        + "\\u2001" // EM QUAD 
                        + "\\u2002" // EN SPACE
                        + "\\u2003" // EM SPACE
                        + "\\u2004" // THREE-PER-EM SPACE
                        + "\\u2005" // FOUR-PER-EM SPACE
                        + "\\u2006" // SIX-PER-EM SPACE
                        + "\\u2007" // FIGURE SPACE
                        + "\\u2008" // PUNCTUATION SPACE
                        + "\\u2009" // THIN SPACE
                        + "\\u200A" // HAIR SPACE
                        + "\\u2028" // LINE SEPARATOR
                        + "\\u2029" // PARAGRAPH SEPARATOR
                        + "\\u202F" // NARROW NO-BREAK SPACE
                        + "\\u205F" // MEDIUM MATHEMATICAL SPACE
                        + "\\u3000" // IDEOGRAPHIC SPACE
                        ;        
/* A \s that actually works for Java’s native character set: Unicode */
String     whitespace_charclass = "["  + whitespace_chars + "]";    
/* A \S that actually works for  Java’s native character set: Unicode */
String not_whitespace_charclass = "[^" + whitespace_chars + "]";

Now you can use whitespace_charclass + "+" as the pattern in your replaceAll.

Sorry ’bout all that. Java’s regexes just don’t work very well on its own native character set, and so you really have to jump through exotic hoops to make them work.

And if you think white space is bad, you should see what you have to do to get \w and \b to finally behave properly!

Yes, it’s possible, and yes, it’s a mindnumbing mess. That’s being charitable, even. The easiest way to get a standards-comforming regex library for Java is to JNI over to ICU’s stuff. That’s what Google does for Android, because OraSun’s doesn’t measure up.

If you don’t want to do that but still want to stick with Java, I have a front-end regex rewriting library I wrote that “fixes” Java’s patterns, at least to get them conform to the requirements of RL1.2a in UTS#18, Unicode Regular Expressions.

Depending on what you mean, either redirect or use curl.

Have been using DBCP for a couple of years now in production. It is stable, survives DB server reboot. Just configure it properly. It only requires a handful of parameters to be specified so don't be lazy. Here is a snippet from our system production code which lists parameters that we explicitly set to make it work:

DriverAdapterCPDS driverAdapterCPDS = new DriverAdapterCPDS();
driverAdapterCPDS.setUrl(dataSourceProperties.getProperty("url"));
driverAdapterCPDS.setUser(dataSourceProperties.getProperty("username"));
driverAdapterCPDS.setPassword(dataSourceProperties.getProperty("password"));
driverAdapterCPDS.setDriver(dataSourceProperties.getProperty("driverClass"));

driverAdapterCPDS.setMaxActive(Integer.valueOf(dataSourceProperties.getProperty("maxActive")));
driverAdapterCPDS.setMaxIdle(Integer.valueOf(dataSourceProperties.getProperty("maxIdle")));
driverAdapterCPDS.setPoolPreparedStatements(Boolean.valueOf(dataSourceProperties.getProperty("poolPreparedStatements")));

SharedPoolDataSource poolDataSource = new SharedPoolDataSource();
poolDataSource.setConnectionPoolDataSource(driverAdapterCPDS);
poolDataSource.setMaxWait(Integer.valueOf(dataSourceProperties.getProperty("maxWait")));
poolDataSource.setDefaultTransactionIsolation(Integer.valueOf(dataSourceProperties.getProperty("defaultTransactionIsolation")));
poolDataSource.setDefaultReadOnly(Boolean.valueOf(dataSourceProperties.getProperty("defaultReadOnly")));
poolDataSource.setTestOnBorrow(Boolean.valueOf(dataSourceProperties.getProperty("testOnBorrow")));
poolDataSource.setValidationQuery("SELECT 0");

Make sure you are in the correct VirtualEnvironment. I updated PyCharm and for some reason had to point my project at my VE again. Opening the terminal, I was not in my VE when attempting zappa update (and got this error). Restarting PyCharm, all back to normal.

You use the word initialize so it's unclear if this is one-time assignment or can happen multiple times.

If you just need a one time initialization, you can put it in the constructor and use the two iterator vector constructor:

Foo::Foo(double* w, int len) : w_(w, w + len) { }

Otherwise use assign as previously suggested:

void set_data(double* w, int len)
{
    w_.assign(w, w + len);
}

_stats/indices gives the result with indices.

$ curl -XGET "localhost:9200/_stats/indices?pretty=true"
{
  "_shards" : {
    "total" : 10,
    "successful" : 5,
    "failed" : 0
  },
  "_all" : {
    "primaries" : { },
    "total" : { }
  },
  "indices" : {
    "visitors" : {
      "primaries" : { },
      "total" : { }
    }
  }
}

In some cases, static methods can be difficult to test, especially if they need to be mocked, which is why most mocking frameworks don't support them. I found this blog post to be very useful in determining how to mock static methods and classes.

You can't. That member is private, it's not visible outside the class. That's the whole point of the public/protected/private modifiers.

(You could probably use dirty pointer tricks though, but my guess is that you'd enter undefined behavior territory pretty fast.)

I figured it out. I was using a bad example I found in the past of how to map query string to the method parameters.

In case anyone else needs it, in order to have optional parameters in a query string such as:

• ~/api/products/filter?apc=AA&xpc=BB
• ~/api/products/filter?sku=7199123

you would use:

[Route("products/filter/{apc?}/{xpc?}/{sku?}")]
public IHttpActionResult Get(string apc = null, string xpc = null, int? sku = null)
{ ... }

It seems odd to have to define default values for the method parameters when these types already have a default.

Try realpath.

~ $ sudo apt-get install realpath  # may already be installed
~ $ realpath .bashrc
/home/username/.bashrc

To avoid expanding symlinks, use realpath -s.

The answer comes from "bash/fish command to print absolute path to a file".

if you use a negative translateX/Y width and height are not necessary and the style is really short

#form_login {
    left      : 50%;
    top       : 50%;
    position  : absolute;
    transform : translate(-50%, -50%);
}

<form id="form_login">
  <p> 
      <input type="text" id="username" placeholder="username" />
  </p>
  <p>
      <input type="password" id="password" placeholder="password" />
  </p>
  <p>
      <input type="text" id="server" placeholder="server" />
  </p>
  <p>
      <button id="submitbutton" type="button">Se connecter</button>
  </p>
</form>

Alternatively you could use display: grid (check the full page view)

body {
   margin        : 0;
   padding       : 0;
   display       : grid;
   place-content : center;
   min-height    : 100vh;
}

<form id="form_login">
  <p> 
      <input type="text" id="username" placeholder="username" />
  </p>
  <p>
      <input type="password" id="password" placeholder="password" />
  </p>
  <p>
      <input type="text" id="server" placeholder="server" />
  </p>
  <p>
      <button id="submitbutton" type="button">Se connecter</button>
  </p>
</form>

In Centos 6.7, in my case the library file /usr/lib64/php/modules/sqlite3.so was missing.

yum install php-pdo 

vim /etc/php.d/sqlite3.ini
; Enable sqlite3 extension module
extension=sqlite3.so

sudo service httpd restart

You could change the @RequestParam type to an Integer and make it not required. This would allow your request to succeed, but it would then be null. You could explicitly set it to your default value in the controller method:

@RequestMapping(value = "/test", method = RequestMethod.POST)
@ResponseBody
public void test(@RequestParam(value = "i", required=false) Integer i) {
    if(i == null) {
        i = 10;
    }
    // ...
}

I have removed the defaultValue from the example above, but you may want to include it if you expect to receive requests where it isn't set at all:

http://example.com/test

Please find the require.js module that I wrote for Offline.

define(['offline'], function (Offline) {
    //Tested with Chrome and IE11 Latest Versions as of 20140412
    //Offline.js - http://github.hubspot.com/offline/ 
    //Offline.js is a library to automatically alert your users 
    //when they've lost internet connectivity, like Gmail.
    //It captures AJAX requests which were made while the connection 
    //was down, and remakes them when it's back up, so your app 
    //reacts perfectly.

    //It has a number of beautiful themes and requires no configuration.
    //Object that will be exposed to the outside world. (Revealing Module Pattern)

    var OfflineDetector = {};

    //Flag indicating current network status.
    var isOffline = false;

    //Configuration Options for Offline.js
    Offline.options = {
        checks: {
            xhr: {
                //By default Offline.js queries favicon.ico.
                //Change this to hit a service that simply returns a 204.
                url: 'favicon.ico'
            }
        },

        checkOnLoad: true,
        interceptRequests: true,
        reconnect: true,
        requests: true,
        game: false
    };

    //Offline.js raises the 'up' event when it is able to reach
    //the server indicating that connection is up.
    Offline.on('up', function () {
        isOffline = false;
    });

    //Offline.js raises the 'down' event when it is unable to reach
    //the server indicating that connection is down.
    Offline.on('down', function () {
        isOffline = true;
    });

    //Expose Offline.js instance for outside world!
    OfflineDetector.Offline = Offline;

    //OfflineDetector.isOffline() method returns the current status.
    OfflineDetector.isOffline = function () {
        return isOffline;
    };

    //start() method contains functionality to repeatedly
    //invoke check() method of Offline.js.
    //This repeated call helps in detecting the status.
    OfflineDetector.start = function () {
        var checkOfflineStatus = function () {
            Offline.check();
        };
        setInterval(checkOfflineStatus, 3000);
    };

    //Start OfflineDetector
    OfflineDetector.start();
    return OfflineDetector;
});

Please read this blog post and let me know your thoughts. http://zen-and-art-of-programming.blogspot.com/2014/04/html-5-offline-application-development.html It contains a code sample using offline.js to detect when the client is offline.

you can find if one has been initialized by comparing the references with the default instance:

GRPCContainer container = myGrpcResponseBean.getContainer();
if (container.getDefaultInstanceForType() != container) {
...
}

You can access the $_SERVER['DOCUMENT_ROOT'] variable :

<?php 
   $path = $_SERVER['DOCUMENT_ROOT'];
   $path .= "/subdir1/yourdocument.txt";
?>

There are two ways to run tomcat in debug mode

1. Using jdpa run

2. Using JAVA_OPTS

I ended up finding MinimalistTelnet and adapted it to my uses. I ended up needing to be able to heavily modify the code due to the unique** device that I am attempting to attach to.

** Unique in this instance can be validly interpreted as brain-dead.

Try adding this class

class="pager"

<p class="pager" style="line-height: 70px;">
    <button type="submit" class="btn">Confirm</button>
</p>

I tried mine within a <div class=pager><button etc etc></div> which worked well

See http://getbootstrap.com/components/ look under Pagination -> Pager

This looks like the correct bootstrap class to center this, text-align: center; is meant for text not images and blocks etc.

JLabel is actually capable of displaying some rudimentary HTML, which is why it is not responding to your use of the newline character (unlike, say, System.out).

If you put in the corresponding HTML and used <BR>, you would get your newlines.

Swift 3

You can simply use this method to remove all normal spaces in a string (doesn't consider all types of whitespace):

let myString = " Hello World ! "
let formattedString = myString.replacingOccurrences(of: " ", with: "")

The result will be:

HelloWorld!

shutil.rmtree() for most cases. But it doesn't work for in Windows for readonly files. For windows import win32api and win32con modules from PyWin32.

def rmtree(dirname):
    retry = True
    while retry:
        retry = False
        try:
            shutil.rmtree(dirname)
        except exceptions.WindowsError, e:
            if e.winerror == 5: # No write permission
                win32api.SetFileAttributes(dirname, win32con.FILE_ATTRIBUTE_NORMAL)
                retry = True

You can use OnClientClick event to call a JavaScript function:

<asp:Button ID="Button1" runat="server" Text="Button" onclientclick='redirect()' />

JavaScript code:

function redirect() {
  location.href = 'page.aspx';
}

But i think the best would be to style a hyperlink with css.

Example :

.button {
  display: block;
  height: 25px;
  background: #f1f1f1;
  padding: 10px;
  text-align: center;
  border-radius: 5px;
  border: 1px solid #e1e1e2;
  color: #000;
  font-weight: bold;
}

Instead of WorksheetFunction.Vlookup, you can use Application.Vlookup. If you set a Variant equal to this it returns Error 2042 if no match is found. You can then test the variant - cellNum in this case - with IsError:

Sub test()
Dim ws As Worksheet: Set ws = Sheets("2012")
Dim rngLook As Range: Set rngLook = ws.Range("A:M")
Dim currName As String
Dim cellNum As Variant

'within a loop
currName = "Example"
cellNum = Application.VLookup(currName, rngLook, 13, False)
If IsError(cellNum) Then
    MsgBox "no match"
Else
    MsgBox cellNum
End If
End Sub

The Application versions of the VLOOKUP and MATCH functions allow you to test for errors without raising the error. If you use the WorksheetFunction version, you need convoluted error handling that re-routes your code to an error handler, returns to the next statement to evaluate, etc. With the Application functions, you can avoid that mess.

The above could be further simplified using the IIF function. This method is not always appropriate (e.g., if you have to do more/different procedure based on the If/Then) but in the case of this where you are simply trying to determinie what prompt to display in the MsgBox, it should work:

cellNum = Application.VLookup(currName, rngLook, 13, False)
MsgBox IIF(IsError(cellNum),"no match", cellNum)

Consider those methods instead of On Error ... statements. They are both easier to read and maintain -- few things are more confusing than trying to follow a bunch of GoTo and Resume statements.

Now a days is really easy to set app-icon, just go to https://makeappicon.com/ add your image, they will send you all size of App-icon (Also for watch & itunes as well), now Click Assets.xcassets in the Project navigator and then choose AppIcon. Now you just have to drag n drop the icon as required.

This will keep its space, but not show anything;

opacity: 0.0;

This will hide the object fully, plus its (reserved) space;

display: none;

__call__ allows to return arbitrary values, while __init__ being an constructor returns the instance of class implicitly. As other answers properly pointed out, __init__ is called just once, while it's possible to call __call__ multiple times, in case the initialized instance is assigned to intermediate variable.

>>> class Test:
...     def __init__(self):
...         return 'Hello'
... 
>>> Test()
Traceback (most recent call last):
  File "<console>", line 1, in <module>
TypeError: __init__() should return None, not 'str'
>>> class Test2:
...     def __call__(self):
...         return 'Hello'
... 
>>> Test2()()
'Hello'
>>> 
>>> Test2()()
'Hello'
>>> 

For Ubuntu 14.04 and Android try:

hcitool scan #get hardware address
sudo bluetooth-agent PIN HARDWARE-ADDRESS

PIN dialog pops up on Android device. Enter same PIN.

Note: sudo apt-get install bluez-utils might be necessary.

Note2: If PIN dialog does not appear, try pairing from Android first (will fail because of wrong PIN). Then try again as described above.

If you don't want to implement IEquatable, you can always use Reflection to compare all the properties: - if they're value type, just compare them -if they are reference type, call the function recursively to compare its "inner" properties.

I'm not thinking about performace, but about simplicity. It depends, however on the exact design of your objects. It could get complicated depending on your objects shape (for example if there are cyclic dependencies between properties). There are, however, several solutions out there that you can use, like this one:

• Compare .NET objects

Another option is to serialize the object as text, for example using JSON.NET, and comparing the serialization result. (JSON.NET can handle Cyclic dependencies between properties).

I don't know if by fastest you mean the fastest way to implement it or a code that runs fast. You should not optimize before knowing if you need to. Premature optimization is the root of all evil

in your apps plist file add a row call it "View controller-based status bar appearance" and set it to NO

Note that this simply does not work, if you are using UIImagePickerController in the app.

Do you need to keep your collection sorted at all times? When retrieving the pairs, do you need them to be always sorted, or it's only for a few times (maybe just for presenting)? How big do you expect your collection to be? There are a lot of factors that can help you decide witch method to use.

If you need the collection to be sorted at all times, even when you insert or delete elements and insertion speed is not a problem maybe you should implement some kind of SortedObservableCollection like @Gerrie Schenck mentioned or check out this implementation.

If you need your collection sorted just for a few times use:

my_collection.OrderBy(p => p.Key);

This will take some time to sort the collection, but even so, it might be the best solution depending on what your doing with it.

Don't want to create a drawable resource?

  <FrameLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@android:color/black"
    android:minHeight="128dp">

    <FrameLayout
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:layout_margin="1dp"

You don't need function overloading, as you have the *args and **kwargs arguments.

The fact is that function overloading is based on the idea that passing different types you will execute different code. If you have a dynamically typed language like Python, you should not distinguish by type, but you should deal with interfaces and their compliance with the code you write.

For example, if you have code that can handle either an integer, or a list of integers, you can try iterating on it and if you are not able to, then you assume it's an integer and go forward. Of course it could be a float, but as far as the behavior is concerned, if a float and an int appear to be the same, then they can be interchanged.

Try just =COUNTIF(A2:A51,"iPad")

I had to move the folders inside a folder named "default" to the android-## folder so Eclipse could see the images.

The following PHP worked for me (using mysqli extension but queries should be the same for other extensions):

$db = new mysqli( 'localhost', 'user', 'pass', 'dbname' );
// to get the max_allowed_packet
$maxp = $db->query( 'SELECT @@global.max_allowed_packet' )->fetch_array();
echo $maxp[ 0 ];
// to set the max_allowed_packet to 500MB
$db->query( 'SET @@global.max_allowed_packet = ' . 500 * 1024 * 1024 );

So if you've got a query you expect to be pretty long, you can make sure that mysql will accept it with something like:

$sql = "some really long sql query...";
$db->query( 'SET @@global.max_allowed_packet = ' . strlen( $sql ) + 1024 );
$db->query( $sql );

Notice that I added on an extra 1024 bytes to the length of the string because according to the manual,

The value should be a multiple of 1024; nonmultiples are rounded down to the nearest multiple.

That should hopefully set the max_allowed_packet size large enough to handle your query. I haven't tried this on a shared host, so the same caveat as @Glebushka applies.

if anyone faced problem even after using return false; . then use the below.

setTimeout(function(){document.location.href = "index.php"},500);

Try this:

Write-Host ($obj | Format-Table | Out-String)

or

Write-Host ($obj | Format-List | Out-String)

Use an array for this.

var markers = [];
for (var i = 0; i < coords.length; ++i) {
    markers[i] = "some stuff";
}

Int -->String :

public enum Country {

    US("US",0),
    UK("UK",2),
    DE("DE",1);


    private static Map<Integer, String> domainToCountryMapping; 
    private String country;
    private int domain;

    private Country(String country,int domain){
        this.country=country.toUpperCase();
        this.domain=domain;
    }

    public String getCountry(){
        return country;
    }


    public static String getCountry(String domain) {
        if (domainToCountryMapping == null) {
            initMapping();
        }

        if(domainToCountryMapping.get(domain)!=null){
            return domainToCountryMapping.get(domain);
        }else{
            return "US";
        }

    }

     private static void initMapping() {
         domainToCountryMapping = new HashMap<Integer, String>();
            for (Country s : values()) {
                domainToCountryMapping.put(s.domain, s.country);
            }
        }

I haven't ever seen such a thing, but there is this dev tool that includes a syntax checker for oracle, mysql, db2, and sql server... http://www.sqlparser.com/index.php

However this seems to be just the library. You'd need to build an app to leverage the parser to do what you want. And the Enterprise edition that includes all of the databases would cost you $450... ouch!

EDIT: And, after saying that - it looks like someone might already have done what you want using that library: http://www.wangz.net/cgi-bin/pp/gsqlparser/sqlpp/sqlformat.tpl

The online tool doesn't automatically check against each DB though, you need to run each manually. Nor can I say how good it is at checking the syntax. That you'd need to investigate yourself.

Try this:

DateTime.Now.ToString("yyyy-MM-ddThh:mm:sszzz");

zzz is the timezone offset.

You can use insert to specify where you want to new column to be. In this case, I use 0 to place the new column at the left.

df.insert(0, 'Name', 'abc')

  Name        Date  Open  High  Low  Close
0  abc  01-01-2015   565   600  400    450

conn.escape_string()

Adding to Winnie's great answer,

If anyone is not able to find the postgresql.conf file location in your setup, you can always ask the postgres itself.

SHOW config_file;

For me changing the max_connections alone made the trick.

For multiple times of execution of our model, random state make sure that data values will be same for training and testing data sets. It fixes the order of data for train_test_split

If you are using CocoaPods, the most likely problem is because your Pods project Build Settings for Build Active Architecture Only is set to Yes for Debug.

The solution is simple. Change it to No.

Similarly, change to No for your application project.

#container-of-boxes {
    display: table;
    width: 1158px;
}
#box-1 {
    width: 578px;
}
#box-2 {
    width: 386px;
}
#box-3 {
    width: 194px;
}
#box-1, #box-2, #box-3 {
    min-height: 210px;
    padding-bottom: 20px;
    display: table-cell;
    height: auto;
    overflow: hidden;
}

• The container must have display:table
• The boxes inside container must be: display:table-cell
• Don't put floats.

1) Remember the main reason to separate .h and .cpp files is to hide the class implementation as a separately-compiled Obj code that can be linked to the user’s code that included a .h of the class.

2) Non-template classes have all variables concretely and specifically defined in .h and .cpp files. So the compiler will have the need information about all data types used in the class before compiling/translating ? generating the object/machine code Template classes have no information about the specific data type before the user of the class instantiate an object passing the required data type:

        TClass<int> myObj;

3) Only after this instantiation, the complier generate the specific version of the template class to match the passed data type(s).

4) Therefore, .cpp Can NOT be compiled separately without knowing the users specific data type. So it has to stay as source code within “.h” until the user specify the required data type then, it can be generated to a specific data type then compiled

What about the ansicolors library? You can simple do:

from colors import color, red, blue

# common colors
print(red('This is red'))
print(blue('This is blue'))

# colors by name or code
print(color('Print colors by name or code', 'white', '#8a2be2'))

In the case you are on something else then windows and your boss is forcing you to use azure devops, and you don't want to use SSH, and you want to use to plain old way, do the following.

You have to enable 'Alternate credentials' (I know it's annoying) or you need to create an access token. Creating an access token in this case is more like a temporary random password. If you use the windows tooling it is done for you.

Any way, go to Security in the profile context menu in the right upper corner.

Then if your boss/manager/dude that has the admin rights is favoring you the 'Alternate credentials' are enabled. Otherwise accept your fate and generate a 'Personal access token'.

$(window).scroll( function() { 
 var scrolled_val = $(document).scrollTop().valueOf();
 alert(scrolled_val+ ' = scroll value');
});

This is another way of getting the value of scroll.

I had the following error message Port 80 in use by "Unable to open process" with PID 4! Apache WILL NOT start without the configured ports free! You need to uninstall/disable/reconfigure the blocking application or reconfigure Apache and the Control Panel to listen on a different port Starting Check-Timer Control Panel Ready

opened the httpd.conf and changed the listen port from 80 to 1234 in both places

Listen 12.34.56.78:1234

Listen 1234

Then go to Config for the xampp control panel and go to service and port setting and changed the port from 80 to 1234

That worked.

I may as well add another OS X entry, this one using plain old find with exec (which I prefer over using xargs, as I have seen odd results from very large find result sets with xargs in the past).

Because this is for OS X, I also added in the filtering to either .h or .m files - make sure to copy all the way to the end!

find ./ -type f -name "*.[mh]" -exec wc -l {}  \; | sed -e 's/[ ]*//g' | cut -d"." -f1 | paste -sd+ - | bc

Actually,,i found a simple answer,, Jst adding the object to String Builder instead of String worked ;)

StringBuilder jsonString= new StringBuilder.append("http://www.json-.com/j/cglqaRcMSW?=4");    
JSON json= new JSON(jsonString.toString);

select max( 1 )
  into my_if_has_data
  from MY_TABLE    X
 where X.my_field   = my_condition
   and rownum       = 1;

Not iterating through all records.

If MY_TABLE has no data, then my_if_has_data sets to null.

A SysOps guy once taught me the Three-Fingered Claw technique:

yell() { echo "$0: $*" >&2; }
die() { yell "$*"; exit 111; }
try() { "$@" || die "cannot $*"; }

These functions are *NIX OS and shell flavor-robust. Put them at the beginning of your script (bash or otherwise), try() your statement and code on.

Explanation

(based on flying sheep comment).

• yell: print the script name and all arguments to stderr:
  • $0 is the path to the script ;
  • $* are all arguments.
  • >&2 means > redirect stdout to & pipe 2. pipe 1 would be stdout itself.
• die does the same as yell, but exits with a non-0 exit status, which means “fail”.
• try uses the || (boolean OR), which only evaluates the right side if the left one failed.
  • $@ is all arguments again, but different.

A bad feature of Anil's function above is that it requires the user to always manually specify the second argument to be an empty list []. This should instead be a default. Due to the way Python objects work, these should be set inside the function, not in the arguments.

Here's a working function:

def list_flatten(l, a=None):
    #check a
    if a is None:
        #initialize with empty list
        a = []

    for i in l:
        if isinstance(i, list):
            list_flatten(i, a)
        else:
            a.append(i)
    return a

Testing:

In [2]: lst = [1, 2, [3], [[4]],[5,[6]]]

In [3]: lst
Out[3]: [1, 2, [3], [[4]], [5, [6]]]

In [11]: list_flatten(lst)
Out[11]: [1, 2, 3, 4, 5, 6]

MarginTop should be marginTop.

You're synchronizing twice, which is pointless and possibly slows down the code: changes while iterating over the list need a synchronnization over the entire operation, which you are doing with synchronized (in_queue_list) Using Collections.synchronizedList() is superfluous in that case (it creates a wrapper that synchronizes individual operations).

However, since you are emptying the list completely, the iterated removal of the first element is the worst possible way to do it, sice for each element all following elements have to be copied, making this an O(n^2) operation - horribly slow for larger lists.

Instead, simply call clear() - no iteration needed.

Edit: If you need the single-method synchronization of Collections.synchronizedList() later on, then this is the correct way:

List<Record> in_queue_list = Collections.synchronizedList(in_queue);
in_queue_list.clear(); // synchronized implicitly, 

But in many cases, the single-method synchronization is insufficient (e.g. for all iteration, or when you get a value, do computations based on it, and replace it with the result). In that case, you have to use manual synchronization anyway, so Collections.synchronizedList() is just useless additional overhead.

$("#year").datepicker( {
    format: "yyyy",
    viewMode: "years", 
    minViewMode: "years"
}).on('changeDate', function(e){
    $(this).datepicker('hide');
});

Here is a function to do it and seems reasonably fast.

endv<-function(vec,val) 
{
if(val>length(vec))
{
stop("Length of value greater than length of vector")
}else
{
vec[((length(vec)-val)+1):length(vec)]
}
}

USAGE:

test<-c(0,1,1,0,0,1,1,NA,1,1)
endv(test,5)
endv(LETTERS,5)

BENCHMARK:

                                                    test replications elapsed relative
1                                 expression(tail(x, 5))       100000    5.24    6.469
2 expression(x[seq.int(to = length(x), length.out = 5)])       100000    0.98    1.210
3                       expression(x[length(x) - (4:0)])       100000    0.81    1.000
4                                 expression(endv(x, 5))       100000    1.37    1.691

Reading files using Java NIO's FileChannel and MappedByteBuffer will most likely result in a solution that will be much faster than any solution involving FileInputStream. Basically, memory-map large files, and use direct buffers for small ones.

I had the same problem, and none of the above solutions worked. Actually, the file include/boost/version.hpp could not be read (by the cmake script launched by jenkins).

I had to manually change the permission of the (boost) library (even though jenkins belongs to the group, but that is another problem linked to jenkins that I could not figure out):

chmod o+wx ${BOOST_ROOT} -R # allow reading/execution on the whole library
#chmod g+wx ${BOOST_ROOT} -R # this did not suffice, strangely, but it is another story I guess

Find the custom validator for min number validation. The selector name of our directive is customMin.

custom-min-validator.directive.ts

import { Directive, Input } from '@angular/core';
import { NG_VALIDATORS, Validator, FormControl } from '@angular/forms';

@Directive({
  selector: '[customMin][formControlName],[customMin][formControl],[customMin][ngModel]',
  providers: [{provide: NG_VALIDATORS, useExisting: CustomMinDirective, multi: true}]
})
export class CustomMinDirective implements Validator {
  @Input()
  customMin: number;

  validate(c: FormControl): {[key: string]: any} {
      let v = c.value;
      return ( v < this.customMin)? {"customMin": true} : null;
  }
} 

Find the custom validator for max number validation. The selector name of our directive is customMax.

custom-max-validator.directive.ts

import { Directive, Input } from '@angular/core';
import { NG_VALIDATORS, Validator, FormControl } from '@angular/forms';

@Directive({
  selector: '[customMax][formControlName],[customMax][formControl],[customMax][ngModel]',
  providers: [{provide: NG_VALIDATORS, useExisting: CustomMaxDirective, multi: true}]
})
export class CustomMaxDirective implements Validator {
  @Input()
  customMax: number;

  validate(c: FormControl): {[key: string]: any} {
      let v = c.value;
      return ( v > this.customMax)? {"customMax": true} : null;
  }
} 

We can use customMax with formControlName, formControl and ngModel attributes.

Using Custom Min and Max Validator in Template-driven Form

We will use our custom min and max validator in template-driven form. For min number validation we have customMin attribute and for max number validation we have customMax attribute. Now find the code snippet for validation.

<input name="num1" [ngModel]="user.num1" customMin="15" #numberOne="ngModel">
<input name="num2" [ngModel]="user.num2" customMax="50"  #numberTwo="ngModel"> 

We can show validation error messages as following.

<div *ngIf="numberOne.errors?.customMin"> 
     Minimum required number is 15.
</div>  

<div *ngIf="numberTwo.errors?.customMax"> 
     Maximum number can be 50.
</div> 

To assign min and max number we can also use property biding. Suppose we have following component properties.

minNum = 15;
maxNum = 50; 

Now use property binding for customMin and customMax as following.

<input name="num1" [ngModel]="user.num1" [customMin]="minNum" #numberOne="ngModel">
<input name="num2" [ngModel]="user.num2" [customMax]="maxNum"  #numberTwo="ngModel"> 

UPDATE 4

Same like update 3 but with modern css (=less rules) so that no special positioning on the pseudo element is required.

#box {_x000D_
    background-color: #3D6AA2;_x000D_
    width: 160px;_x000D_
    height: 90px;_x000D_
    position: absolute;_x000D_
    top: calc(10% - 10px);_x000D_
    left: calc(50% - 80px);_x000D_
}_x000D_
_x000D_
.box-shadow:after {_x000D_
    content:"";_x000D_
    position:absolute;_x000D_
    width:100%;_x000D_
    bottom:1px;_x000D_
    z-index:-1;_x000D_
    transform:scale(.9);_x000D_
    box-shadow: 0px 0px 8px 2px #000000;_x000D_
}

<div id="box" class="box-shadow"></div>

UPDATE 3

All my previous answers have been using extra markup to get create this effect, which is not necessarily needed. I think this a much cleaner solution... the only trick is playing around with the values to get the right positioning of the shadow as well as the right strength/opacity of the shadow. Here's a new fiddle, using pseudo-elements:

http://jsfiddle.net/UnsungHero97/ARRRZ/2/

HTML

<div id="box" class="box-shadow"></div>

CSS

#box {
    background-color: #3D6AA2;
    width: 160px;
    height: 90px;
    margin-top: -45px;
    margin-left: -80px;
    position: absolute;
    top: 50%;
    left: 50%;
}

.box-shadow:after {
    content: "";
    width: 150px;
    height: 1px;
    margin-top: 88px;
    margin-left: -75px;
    display: block;
    position: absolute;
    left: 50%;
    z-index: -1;
    -webkit-box-shadow: 0px 0px 8px 2px #000000;
       -moz-box-shadow: 0px 0px 8px 2px #000000;
            box-shadow: 0px 0px 8px 2px #000000;
}

UPDATE 2

Apparently, you can do this with just an extra parameter to the box-shadow CSS as everyone else just pointed out. Here's the demo:

http://jsfiddle.net/K88H9/821/

CSS

-webkit-box-shadow: 0 4px 4px -2px #000000;
   -moz-box-shadow: 0 4px 4px -2px #000000;
        box-shadow: 0 4px 4px -2px #000000;

This would be a better solution. The extra parameter that is added is described as:

The fourth length is a spread distance. Positive values cause the shadow shape to expand in all directions by the specified radius. Negative values cause the shadow shape to contract.

UPDATE

Check out the demo at jsFiddle: http://jsfiddle.net/K88H9/4/

What I did was create a "shadow element" that would hide behind the actual element that you would want to have a shadow. I made the width of the "shadow element" to be exactly less wide than the actual element by 2 times the shadow you specify; then I aligned it properly.

HTML

<div id="wrapper">
    <div id="element"></div>
    <div id="shadow"></div>
</div>

CSS

#wrapper {
    width: 84px;
    position: relative;
}
#element {
    background-color: #3D668F;
    height: 54px;
    width: 100%;
    position: relative;
    z-index: 10;
}
#shadow {
    background-color: #3D668F;
    height: 8px;
    width: 80px;
    margin-left: -40px;
    position: absolute;
    bottom: 0px;
    left: 50%;
    z-index: 5;
    -webkit-box-shadow: 0px 2px 4px #000000;
       -moz-box-shadow: 0px 2px 4px #000000;
            box-shadow: 0px 2px 4px #000000;
}

Original Answer

Yes, you can do this with the same syntax you have provided. The first value controls the horizontal positioning and the second value controls the vertical positioning. So just set the first value to 0px and the second to whatever offset you'd like as follows:

-webkit-box-shadow: 0px 5px #000000;
   -moz-box-shadow: 0px 5px #000000;
        box-shadow: 0px 5px #000000;

I hope this helps.

I'm posting this just in case someone need it..

Just create a button:

<button type="button" href="javascript:void(0);" onclick="mytable.fnDraw();">Refresh</button>

but don't forget to add this when calling the datatable:

mytable = $("#mytable").dataTable();

Convert from any classic base to any base in C#

String number = "100";
int fromBase = 16;
int toBase = 10;

String result = Convert.ToString(Convert.ToInt32(number, fromBase), toBase);

// result == "256"

Supported bases are 2, 8, 10 and 16

DATE_FORMAT(FROM_UNIXTIME(`orderdate`), '%Y-%m-%d %H:%i:%s') as "Date" FROM `orders`

This is the ultimate solution if the given date is in encoded format like 1300464000
