Use pass for no-op:

if x == 0:
  pass
else:
  print "x not equal 0"

And here's another example:

def f():
  pass

Or:

class c:
  pass

You could try something like the code below to be able to work with choices from the variable 'accepted' show here:

print( 'accepted: {}'.format(accepted) )
# accepted: {'yes': ['', 'Yes', 'yes', 'YES', 'y', 'Y'], 'no': ['No', 'no', 'NO', 'n', 'N']}

Here is the code ..

#!/usr/bin/python3

def makeChoi(yeh, neh):
    accept = {}
    # for w in words:
    accept['yes'] = [ '', yeh, yeh.lower(), yeh.upper(), yeh.lower()[0], yeh.upper()[0] ]
    accept['no'] = [ neh, neh.lower(), neh.upper(), neh.lower()[0], neh.upper()[0] ]
    return accept

accepted = makeChoi('Yes', 'No')

def doYeh():
    print('Yeh! Let\'s do it.')

def doNeh():
    print('Neh! Let\'s not do it.')

choi = None
while not choi:
    choi = input( 'Please choose: Y/n? ' )
    if choi in accepted['yes']:
        choi = True
        doYeh()
    elif choi in accepted['no']:
        choi = True
        doNeh()
    else:
        print('Your choice was "{}". Please use an accepted input value ..'.format(choi))
        print( accepted )
        choi = None

Do you mean like this

int index = 2;
string s = "hello";
Console.WriteLine(s[index]);

string also implements IEnumberable<char> so you can also enumerate it like this

foreach (char c in s)
    Console.WriteLine(c);

The reason why your code is slow is that your LDAP query retrieves every single user object in your domain even though you're only interested in one user with a common name of "Adit":

dSearcher.Filter = "(&(objectClass=user))";

So to optimize, you need to narrow your LDAP query to just the user you are interested in. Try something like:

dSearcher.Filter = "(&(objectClass=user)(cn=Adit))";

In addition, don't forget to dispose these objects when done:

• DirectoryEntry dEntry
• DirectorySearcher dSearcher

As I wrote in my comment, the solution to your problem is to write the following:

Set hyperLinkText = hprlink.Range

Set is needed because TextRange is a class, so hyperLinkText is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.

Use atoi() from <stdlib.h>

http://linux.die.net/man/3/atoi

Or, write your own atoi() function which will convert char* to int

int a2i(const char *s)
{
  int sign=1;
  if(*s == '-'){
    sign = -1;
    s++;
  }
  int num=0;
  while(*s){
    num=((*s)-'0')+num*10;
    s++;   
  }
  return num*sign;
}

WHERE DATEDIFF(day, tstamp, @dateParam) = 0

This should get you there if you don't care about time.

This is to answer the meta question of comparing the dates of two values when you don't care about the time.

our project surely is configured as "library" thats why you get the message : "Android library projects cannot be launched."

right-click in your project and select Properties. In the Properties window -> "Android" -> uncheck the option "is Library" and apply -> Click "ok" to close the properties window.

Loop through the file.

f = open("masters.txt")
lines = f.readlines()
for line in lines:
    print line

I used below ms sql script pattern several times successfully which uses Try-Catch,Commit Transaction- Rollback Transaction,Error Tracking.

Your TRY block will be as follows

 BEGIN TRY
 BEGIN TRANSACTION T
 ----
 //your script block
 ----
 COMMIT TRANSACTION T 
 END TRY

Your CATCH block will be as follows

BEGIN CATCH
DECLARE @ErrMsg NVarChar(4000), 
        @ErrNum Int, 
        @ErrSeverity Int, 
        @ErrState Int, 
        @ErrLine Int, 
        @ErrProc NVarChar(200)
 SELECT @ErrNum = Error_Number(), 
       @ErrSeverity = Error_Severity(), 
       @ErrState = Error_State(), 
       @ErrLine = Error_Line(), 
       @ErrProc = IsNull(Error_Procedure(), '-')
 SET @ErrMsg = N'ErrLine: ' + rtrim(@ErrLine) + ', proc: ' + RTRIM(@ErrProc) + ', 
       Message: '+ Error_Message()

Your ROLLBACK script will be part of CATCH block as follows

IF (@@TRANCOUNT) > 0 
BEGIN
PRINT 'ROLLBACK: ' + SUBSTRING(@ErrMsg,1,4000)
ROLLBACK TRANSACTION T
END
ELSE
BEGIN
PRINT SUBSTRING(@ErrMsg,1,4000);   
END

END CATCH

Above different script blocks you need to use as one block. If any error happens in the TRY block it will go the the CATCH block. There it is setting various details about the error number,error severity,error line ..etc. At last all these details will get append to @ErrMsg parameter. Then it will check for the count of transaction (@@TRANCOUNT >0) , ie if anything is there in the transaction for rollback. If it is there then show the error message and ROLLBACK TRANSACTION. Otherwise simply print the error message.

We have kept our COMMIT TRANSACTION T script towards the last line of TRY block in order to make sure that it should commit the transaction(final change in the database) only after all the code in the TRY block has run successfully.

shared folders VS synced folders

Basically shared folders are renamed to synced folder from v1 to v2 (docs), under the bonnet it is still using vboxsf between host and guest (there is known performance issues if there are large numbers of files/directories).

Vagrantfile directory mounted as /vagrant in guest

Vagrant is mounting the current working directory (where Vagrantfile resides) as /vagrant in the guest, this is the default behaviour.

See docs

NOTE: By default, Vagrant will share your project directory (the directory with the Vagrantfile) to /vagrant.

You can disable this behaviour by adding cfg.vm.synced_folder ".", "/vagrant", disabled: true in your Vagrantfile.

Why synced folder is not working

Based on the output /tmp on host was NOT mounted during up time.

Use VAGRANT_INFO=debug vagrant up or VAGRANT_INFO=debug vagrant reload to start the VM for more output regarding why the synced folder is not mounted. Could be a permission issue (mode bits of /tmp on host should be drwxrwxrwt).

I did a test quick test using the following and it worked (I used opscode bento raring vagrant base box)

config.vm.synced_folder "/tmp", "/tmp/src"

output

$ vagrant reload

How about using this method?

HashSet<Integer> zipcodeSet = new HashSet<Integer>(Arrays.asList(zipcodeList));
duplicates = zipcodeSet.size()!=zipcodeList.length;

Bear in mind that I speak ASFAC++B. :) I've put the most important differentiating factor first.

Garbage Collection

Garbage Collection (GC) is the single most important factor in differentiating between these languages.

While C and C++ can be used with GC, it is a bolted-on afterthought and cannot be made to work as well (the best known is here) - it has to be "conservative" which means that it cannot collect all unused memory.

C# is designed from the ground up to work on a GC platform, with standard libraries also designed that way. It makes an absolutely fundamental difference to developer productivity that has to be experienced to be believed.

There is a belief widespread among C/C++ users that GC equates with "bad performance". But this is out-of-date folklore (even the Boehm collector on C/C++ performs much better than most people expect it to). The typical fear is of "long pauses" where the program stops so the GC can do some work. But in reality these long pauses happen with non-GC programs, because they run on top of a virtual memory system, which occasionally interrupts to move data between physical memory and disk.

There is also widespread belief that GC can be replaced with shared_ptr, but it can't; the irony is that in a multi-threaded program, shared_ptr is slower than a GC-based system.

There are environments that are so frugal that GC isn't practical - but these are increasingly rare. Cell phones typically have GC. The CLR's GC that C# typically runs on appears to be state-of-the-art.

Since adopting C# about 18 months ago I've gone through several phases of pure performance tuning with a profiler, and the GC is so efficient that it is practically invisible during the operation of the program.

GC is not a panacea, it doesn't solve all programming problems, it only really cleans up memory allocation, if you're allocating very large memory blocks then you will still need to take some care, and it is still possible to have what amounts to a memory leak in a sufficiently complex program - and yet, the effect of GC on productivity makes it a pretty close approximation to a panacea!

Undefined Behaviour

C++ is founded on the notion of undefined behaviour. That is, the language specification defines the outcome of certain narrowly defined usages of language features, and describes all other usages as causing undefined behaviour, meaning in principle that the operation could have any outcome at all (in practice this means hard-to-diagnose bugs involving apparently non-deterministic corruption of data).

Almost everything about C++ touches on undefined behaviour. Even very nice forthcoming features like lambda expressions can easily be used as convenient way to corrupt the stack (capture a local by reference, allow the lambda instance to outlive the local).

C# is founded on the principle that all possible operations should have defined behaviour. The worst that can happen is an exception is thrown. This completely changes the experience of software construction.

(There's unsafe mode, which has pointers and therefore undefined behaviour, but that is strongly discouraged for general use - think of it as analogous to embedded assembly language.)

Complexity

In terms of complexity, C++ has to be singled out, especially if we consider the very-soon-to-be standardized new version. C++ does absolutely everything it can to make itself effective, short of assuming GC, and as a result it has an awesome learning curve. The language designers excuse much of this by saying "Those features are only for library authors, not ordinary users" - but to be truly effective in any language, you need to build your code as reusable libraries. So you can't escape.

On the positive side, C++ is so complex, it's like a playground for nerds! I can assure you that you would have a lot of fun learning how it all fits together. But I can't seriously recommend it as a basis for productive new work (oh, the wasted years...) on mainstream platforms.

C keeps the language simple (simple in the sense of "the compiler is easy to write"), but this makes the coding techniques more arcane.

Note that not all new language features equate with added complexity. Some language features are described as "syntactic sugar", because they are shorthand that the compiler expands for you. This is a good way to think of a great deal of the enhancements to C# over recent years. The language standard even specifies some features by giving the translation to longhand, e.g. using statement expands into try/finally.

At one point, it was possible to think of C++ templates in the same way. But they've since become so powerful that they are now form the basis of a whole separate dimension of the language, with its own enthusiastic user communities and idioms.

Libraries

The strangest thing about C and C++ is that they don't have a standard interchangeable form of pre-compiled library. Integrating someone else's code into your project is always a little fiddly, with obscure decisions to be made about how you'll be linking to it.

Also, the standard library is extremely basic - C++ has a complete set of data structures and a way of representing strings (std::string), but that's still minimal. Is there a standard way of finding a list of files in a directory? Amazingly, no! Is there standard library support for parsing or generating XML? No. What about accessing databases? Be serious! Writing a web site back-end? Are you crazy? etc.

So you have to go hunting further afield. For XML, try Xerces. But does it use std::string to represent strings? Of course not!

And do all these third-party libraries have their own bizarre customs for naming classes and functions? You betcha!

The situation in C# couldn't be more different; the fundamentals were in place from the start, so everything inter-operates beautifully (and because the fundamentals are supplied by the CLR, there is cross-language support).

It's not all perfect; generics should have been in place from the start but wasn't, which does leave a visible scar on some older libraries; but it is usually trivial to fix this externally. Also a number of popular libraries are ported from Java, which isn't as good a fit as it first appears.

Closures (Anonymous Methods with Local Variable Capture)

Java and C are practically the last remaining mainstream languages to lack closures, and libraries can be designed and used much more neatly with them than without (this is one reason why ported Java libraries sometimes seem clunky to a C# user).

The amusing thing about C++ is that its standard library was designed as if closures were available in the language (container types, <algorithm>, <functional>). Then ten years went by, and now they're finally being added! They will have a huge impact (although, as noted above, they leak underfined behaviour).

C# and JavaScript are the most widely used languages in which closures are "idiomatically established". (The major difference between those languages being that C# is statically typed while JavaScript is dynamically typed).

Platform Support

I've put this last only because it doesn't appear to differentiate these languages as much as you might think. All these languages can run on multiple OSes and machine architectures. C is the most widely-supported, then C++, and finally C# (although C# can be used on most major platforms thanks to an open source implementation called Mono).

My experience of porting C++ programs between Windows and various Unix flavours was unpleasant. I've never tried porting anything very complex in C# to Mono, so I can't comment on that.

No. There is no such option available from Oracle SQL Developer.

You have to execute a query by hand or use other tool (For instance PLSQL Developer has such option). The following SQL is that one used by PLSQL Developer:

select table_name, constraint_name, status, owner
from all_constraints
where r_owner = :r_owner
and constraint_type = 'R'
and r_constraint_name in
 (
   select constraint_name from all_constraints
   where constraint_type in ('P', 'U')
   and table_name = :r_table_name
   and owner = :r_owner
 )
order by table_name, constraint_name

Where r_owner is the schema, and r_table_name is the table for which you are looking for references. The names are case sensitive

Be careful because on the reports tab of Oracle SQL Developer there is the option "All tables / Dependencies" this is from ALL_DEPENDENCIES which refers to "dependencies between procedures, packages, functions, package bodies, and triggers accessible to the current user, including dependencies on views created without any database links.". Then, this report have no value for your question.

Please check your hosts file in etc folder and add below comments then run wamp server.

127.0.0.1 localhost

Path : C:\Windows\System32\drivers\etc

You can use .toString method to convert Uri to String in java

Uri uri = Uri.parse("Http://www.google.com");

String url = uri.toString();

This method convert Uri to String easily

To Save your bitmap in sdcard use the following code

Store Image

private void storeImage(Bitmap image) {
    File pictureFile = getOutputMediaFile();
    if (pictureFile == null) {
        Log.d(TAG,
                "Error creating media file, check storage permissions: ");// e.getMessage());
        return;
    } 
    try {
        FileOutputStream fos = new FileOutputStream(pictureFile);
        image.compress(Bitmap.CompressFormat.PNG, 90, fos);
        fos.close();
    } catch (FileNotFoundException e) {
        Log.d(TAG, "File not found: " + e.getMessage());
    } catch (IOException e) {
        Log.d(TAG, "Error accessing file: " + e.getMessage());
    }  
}

To Get the Path for Image Storage

/** Create a File for saving an image or video */
private  File getOutputMediaFile(){
    // To be safe, you should check that the SDCard is mounted
    // using Environment.getExternalStorageState() before doing this. 
    File mediaStorageDir = new File(Environment.getExternalStorageDirectory()
            + "/Android/data/"
            + getApplicationContext().getPackageName()
            + "/Files"); 

    // This location works best if you want the created images to be shared
    // between applications and persist after your app has been uninstalled.

    // Create the storage directory if it does not exist
    if (! mediaStorageDir.exists()){
        if (! mediaStorageDir.mkdirs()){
            return null;
        }
    } 
    // Create a media file name
    String timeStamp = new SimpleDateFormat("ddMMyyyy_HHmm").format(new Date());
    File mediaFile;
        String mImageName="MI_"+ timeStamp +".jpg";
        mediaFile = new File(mediaStorageDir.getPath() + File.separator + mImageName);  
    return mediaFile;
} 

EDIT From Your comments i have edited the onclick view in this the button1 and button2 functions will be executed separately.

public onClick(View v){

switch(v.getId()){
case R.id.button1:
//Your button 1 function
break;
case R.id. button2:
//Your button 2 function
break;
} 
}

If you use Vundle, :PluginList.

Enable "resolveJsonModule": true in tsconfig.json file and implement as below code, it's work for me:

const config = require('./config.json');

You should check if you have any other github account marked as "default". When trying to clone a new repo, the client (in my case BitBucket) will try to get the credentials that you have set "as default". Just mark your new credentials "as default" and it will allow you to clone the repo, it worked for me.

REPLACE INTO table(column_list) VALUES(value_list);

is a shorter form of

INSERT OR REPLACE INTO table(column_list) VALUES(value_list);

For REPLACE to execute correctly your table structure must have unique rows, whether a simple primary key or a unique index.

REPLACE deletes, then INSERTs the record and will cause an INSERT Trigger to execute if you have them setup. If you have a trigger on INSERT, you may encounter issues.

This is a work around.. not checked the speed..

INSERT OR IGNORE INTO table (column_list) VALUES(value_list);

followed by

UPDATE table SET field=value,field2=value WHERE uniqueid='uniquevalue'

This method allows a replace to occur without causing a trigger.

Note the "" at the beginning and at the end!

Run a program and pass a Long Filename

cmd /c write.exe "c:\sample documents\sample.txt"

Spaces in Program Path

cmd /c ""c:\Program Files\Microsoft Office\Office\Winword.exe""

Spaces in Program Path + parameters

cmd /c ""c:\Program Files\demo.cmd"" Parameter1 Param2

Spaces in Program Path + parameters with spaces

cmd /k ""c:\batch files\demo.cmd" "Parameter 1 with space" "Parameter2 with space""

Launch Demo1 and then Launch Demo2

cmd /c ""c:\Program Files\demo1.cmd" & "c:\Program Files\demo2.cmd""

CMD.exe (Command Shell)

In addition, you can simply convert byte array to Bitmap.

var bmp = new Bitmap(new MemoryStream(imgByte));

You can also get Bitmap from file Path directly.

Bitmap bmp = new Bitmap(Image.FromFile(filePath));

I have been working with IBM DB2 database for more then decade and now trying to learn PostgreSQL.

It works on PostgreSQL 9.3.4, but does not work on DB2 10.5:

UPDATE B SET
     COLUMN1 = A.COLUMN1,
     COLUMN2 = A.COLUMN2,
     COLUMN3 = A.COLUMN3
FROM A
WHERE A.ID = B.ID

Note: Main problem is FROM cause that is not supported in DB2 and also not in ANSI SQL.

It works on DB2 10.5, but does NOT work on PostgreSQL 9.3.4:

UPDATE B SET
    (COLUMN1, COLUMN2, COLUMN3) =
               (SELECT COLUMN1, COLUMN2, COLUMN3 FROM A WHERE ID = B.ID)

FINALLY! It works on both PostgreSQL 9.3.4 and DB2 10.5:

UPDATE B SET
     COLUMN1 = (SELECT COLUMN1 FROM A WHERE ID = B.ID),
     COLUMN2 = (SELECT COLUMN2 FROM A WHERE ID = B.ID),
     COLUMN3 = (SELECT COLUMN3 FROM A WHERE ID = B.ID)

Use Int32.TryParse as follows.

  int test;
  bool result = Int32.TryParse(value, out test);
  if (result)
  {
     Console.WriteLine("Sucess");         
  }
  else
  {
     if (value == null) value = ""; 
     Console.WriteLine("Failure");
  }

FOR NESTED FRAGMENTS (for example, when using a ViewPager)

In your main activity:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
}

In your main top level fragment(ViewPager fragment):

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    YourFragment frag = (YourFragment) getChildFragmentManager().getFragments().get(viewPager.getCurrentItem());
    frag.yourMethod(data);  // Method for callback in YourFragment
    super.onActivityResult(requestCode, resultCode, data);
}

In YourFragment (nested fragment):

public void yourMethod(Intent data){
    // Do whatever you want with your data
}

This is Oracle bug, memory leak in shared_pool, most likely db managing lots of partitions. Solution: In my opinion patch not exists, check with oracle support. You can try with subpools or en(de)able AMM ...

it's probably better to override the backbutton so you can handle the event before the view is popped for things such as user confirmation.

in viewDidLoad create a UIBarButtonItem and set self.navigationItem.leftBarButtonItem to it passing in a sel

- (void) viewDidLoad
{
// change the back button to cancel and add an event handler
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@”back”
style:UIBarButtonItemStyleBordered
target:self
action:@selector(handleBack:)];

self.navigationItem.leftBarButtonItem = backButton;
[backButton release];

}
- (void) handleBack:(id)sender
{
// pop to root view controller
[self.navigationController popToRootViewControllerAnimated:YES];

}

Then you can do things like raise an UIAlertView to confirm the action, then pop the view controller, etc.

Or instead of creating a new backbutton, you can conform to the UINavigationController delegate methods to do actions when the back button is pressed.

In response to others:

You don't need to specify case in BASH4 just use the ',,' to make a var lowercase. Also I strongly dislike putting code inside of the read block, get the result and deal with it outside of the read block IMO. Also include a 'q' for quit IMO. Lastly why type 'yes' just use -n1 and have the press y.

Example: user can press y/n and also q to just quit.

ans=''
while true; do
    read -p "So is MikeQ the greatest or what (y/n/q) ?" -n1 ans
    case ${ans,,} in
        y|n|q) break;;
        *) echo "Answer y for yes / n for no  or q for quit.";;
    esac
done

echo -e "\nAnswer = $ans"

if [[ "${ans,,}" == "q" ]] ; then
        echo "OK Quitting, we will assume that he is"
        exit 0
fi

if [[ "${ans,,}" == "y" ]] ; then
        echo "MikeQ is the greatest!!"
else
        echo "No? MikeQ is not the greatest?"
fi

This happens at times while using Xcode 9.

There are multiple solution to this as mentioned below :

Note : Make sure that your device is not locked when Xcode is trying to install app.

Solution 1 :

i. Disconnect device and connect again

Solution 2 :

i. Restart you device

Solution 3 :

i. Disconnect device

ii. Quit Xcode (Shortcut key : cmd + Q)

iii. Open your project

iv. Clean project (Shortcut key : cmd + shift + K)

v. Now connect device

vi. Run your project

For me Solution 3 worked perfectly

...and Array.fill() comes to the rescue!

Used to write it all manually before knowing this one ???

Array(length).fill(value)



Array(5).fill('')   =>  ['','','','','']

Array(3).fill({ value: 2 })   =>  [{ value: 2 },{ value: 2 },{ value: 2 }]

Perhps this is what you are looking for.

var pos = 0;
window.onload = function start() {
    setTimeout(slide, 3000);
}
function slide() {
   pos -= 600;
   if (pos === -2400)
     pos = 0;
   document.getElementById('container').style.marginLeft= pos + "px";
   setTimeout(slide, 3000);
}

Just run graphics.off() before plotting your data. This instruction solved my error. So, it's harmless to try it before taking a more complex solution.

One thing I don't think anyone has mentioned, and a stupid mistake I've made in the past (especially when dynamically populating selects). jQuery's .val() won't work for a select input if there isn't an option with a value that matches the value supplied.

Here's a fiddle explaining -> http://jsfiddle.net/go164zmt/

<select id="example">
    <option value="0">Test0</option>
    <option value="1">Test1</option>
</select>

$("#example").val("0");
alert($("#example").val());
$("#example").val("1");
alert($("#example").val());

//doesn't exist
$("#example").val("2");
//and thus returns null
alert($("#example").val());

Just go to your app/storage/logs there logs of error available. Go to filename of today's date time and you will find latest error in your application.

OR

Open app/config/app.php and change setting

'debug' => false,

To

'debug' => true, 

OR

Go to .env file to your application and change the configuratuion

APP_LOG_LEVEL=debug

If you keep in mind that Docker is still running in a VM, the system paths are relative to the VM and not from the Mac Osx system. As it says all is contained in a VM file :

/Users/MyUserName/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/Docker.qcow2

Try to run Alpine image with this volume option and the ls command you are able to list the VM host:

docker run --rm -it -v /:/vm-root alpine:edge ls -l /vm-root

After this just try :

docker run --rm -it -v /:/vm-root alpine:edge ls -l /vm-root/var/lib/docker

Now, you are able to list the docker folder from the VM host

Create a DSN something like this (ASEDEV) for your connection and try to use DSN instead of DRIVER like below:

enter code here
import pyodbc
cnxn = pyodbc.connect('DSN=ASEDEV;User ID=sa;Password=sybase123')
mycur = cnxn.cursor()
mycur.execute("select * from master..sysdatabases")
row = mycur.fetchone()
while row:
    print(row)
    row = mycur.fetchone()`

You cannot change a table while the INSERT trigger is firing. The INSERT might do some locking which could result in a deadlock. Also, updating the table from a trigger would then cause the same trigger to fire again in an infinite recursive loop. Both of these reasons are why MySQL prevents you from doing this.

However, depending on what you're trying to achieve, you can access the new values by using NEW.fieldname or even the old values--if doing an UPDATE--with OLD.

If you had a row named full_brand_name and you wanted to use the first two letters as a short name in the field small_name you could use:

CREATE TRIGGER `capital` BEFORE INSERT ON `brandnames`
FOR EACH ROW BEGIN
  SET NEW.short_name = CONCAT(UCASE(LEFT(NEW.full_name,1)) , LCASE(SUBSTRING(NEW.full_name,2)))
END

I wouldn't advise this, it goes against standard practices, and doesn't offer that much in return. You want to keep the body for content, not options.

You use the JSON class and then call the GetData() function.

Thanks to thetalkingwalnut with answer Windows batch command(s) to read first line from text file I came up with the following solution:

@echo off
for /f "delims=" %%a in ('type sample.txt') do (
echo %%a
exit /b
)

To disable the resize property, use the following CSS property:

resize: none;

• You can either apply this as an inline style property like so:

  <textarea style="resize: none;"></textarea>
  

• or in between <style>...</style> element tags like so:

  textarea {
      resize: none;
  }
  

As mentioned in the comments, there cannot be a continuous scale on variable of the factor type. You could change the factor to numeric as follows, just after you define the meltDF variable.

meltDF$variable=as.numeric(levels(meltDF$variable))[meltDF$variable]

Then, execute the ggplot command

  ggplot(meltDF[meltDF$value == 1,]) + geom_point(aes(x = MW, y =   variable)) +
     scale_x_continuous(limits=c(0, 1200), breaks=c(0, 400, 800, 1200)) +
     scale_y_continuous(limits=c(0, 1200), breaks=c(0, 400, 800, 1200))

And you will have your chart.

To rename any repository of your GitHub account:

1. Go to that particular repository which you want to rename
2. Navigate to the settings tab
3. There, in the repository name section, type the new name you want to put and click Rename

Because you have multiple versions of NumPy installed.

Try pip uninstall numpy and pip list | grep numpy several times, until you see no output from pip list | grep numpy.

Then pip install numpy will get you the newest version of NumPy.

The reason on using the return:false; is well explained on this other question.

For the other issue, you can check for the referrer to see if it is empty:

    function backAway(){
        if (document.referrer == "") { //alternatively, window.history.length == 0
            window.location = "http://www.example.com";
        } else {
            history.back();
        }
    }

<a href="#" onClick="backAway()">Back Button Here.</a>

If you want a destructive backspace, you'll need something like

"\b \b"

i.e. a backspace, a space, and another backspace.

Edit your AndroidManifest.xml to add RECEIVE_BOOT_COMPLETED permission

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

Edit your AndroidManifest.xml application-part for below Permission

<receiver android:enabled="true" android:name=".BootUpReceiver"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
    <intent-filter>
        <action android:name="android.intent.action.BOOT_COMPLETED" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>

Now write below in Activity.

public class BootUpReceiver extends BroadcastReceiver{
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent i = new Intent(context, MyActivity.class);  
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);  
    }
}

I prefer to limit the number of retries, so that if there's a problem with that specific item you will eventually continue onto the next one, thus:

for i in range(100):
  for attempt in range(10):
    try:
      # do thing
    except:
      # perhaps reconnect, etc.
    else:
      break
  else:
    # we failed all the attempts - deal with the consequences.

Has Con Posidielov said, the current route is present in this.props.location.pathname.

But if you want to match a more specific field like a key (or a name), you may use matchPath to find the original route reference.

import { matchPath } from `react-router`

const routes = [{
  key: 'page1'
  exact: true,
  path: '/page1/:someparam/',
  component: Page1,
},
{
  exact: true,
  key: 'page2',
  path: '/page2',
  component: Page2,
},
]

const currentRoute = routes.find(
  route => matchPath(this.props.location.pathname, route)
)

console.log(`My current route key is : ${currentRoute.key}`)

The easiest way for me is doing this:

import datetime
from unittest.mock import Mock, patch

def test():
    datetime_mock = Mock(wraps=datetime.datetime)
    datetime_mock.now.return_value = datetime.datetime(1999, 1, 1)
    with patch('datetime.datetime', new=datetime_mock):
        assert datetime.datetime.now() == datetime.datetime(1999, 1, 1)

CAUTION for this solution: all functionality from datetime module from the target_module will stop working.

$http({
    url: '/api/user',
    method: "POST",
    data: angular.toJson(yourData)
}).success(function (data, status, headers, config) {
    $scope.users = data.users;
}).error(function (data, status, headers, config) {
    $scope.status = status + ' ' + headers;
});

select partition_name,column_name,high_value,partition_position
from ALL_TAB_PARTITIONS a , ALL_PART_KEY_COLUMNS b 
where table_name='YOUR_TABLE' and a.table_name = b.name;

This query lists the column name used as key and the allowed values. make sure, you insert the allowed values(high_value). Else, if default partition is defined, it would go there.

EDIT:

I presume, your TABLE DDL would be like this.

CREATE TABLE HE0_DT_INF_INTERFAZ_MES
  (
    COD_PAIS NUMBER,
    FEC_DATA NUMBER,
    INTERFAZ VARCHAR2(100)
  )
  partition BY RANGE(COD_PAIS, FEC_DATA)
  (
    PARTITION PDIA_98_20091023 VALUES LESS THAN (98,20091024)
  );

Which means I had created a partition with multiple columns which holds value less than the composite range (98,20091024);

That is first COD_PAIS <= 98 and Also FEC_DATA < 20091024

Combinations And Result:

98, 20091024     FAIL
98, 20091023     PASS
99, ********     FAIL
97, ********     PASS
 < 98, ********     PASS

So the below INSERT fails with ORA-14400; because (98,20091024) in INSERT is EQUAL to the one in DDL but NOT less than it.

SQL> INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
                                  VALUES(98, 20091024, 'CTA');  2

            *
ERROR at line 1:

But, we I attempt (97,20091024), it goes through

  2                                    VALUES(97, 20091024, 'CTA');

class LinksParser(HTMLParser.HTMLParser):
  def __init__(self):
    HTMLParser.HTMLParser.__init__(self)
    self.recording = 0
    self.data = []

  def handle_starttag(self, tag, attributes):
    if tag != 'div':
      return
    if self.recording:
      self.recording += 1
      return
    for name, value in attributes:
      if name == 'id' and value == 'remository':
        break
    else:
      return
    self.recording = 1

  def handle_endtag(self, tag):
    if tag == 'div' and self.recording:
      self.recording -= 1

  def handle_data(self, data):
    if self.recording:
      self.data.append(data)

self.recording counts the number of nested div tags starting from a "triggering" one. When we're in the sub-tree rooted in a triggering tag, we accumulate the data in self.data.

The data at the end of the parse are left in self.data (a list of strings, possibly empty if no triggering tag was met). Your code from outside the class can access the list directly from the instance at the end of the parse, or you can add appropriate accessor methods for the purpose, depending on what exactly is your goal.

The class could be easily made a bit more general by using, in lieu of the constant literal strings seen in the code above, 'div', 'id', and 'remository', instance attributes self.tag, self.attname and self.attvalue, set by __init__ from arguments passed to it -- I avoided that cheap generalization step in the code above to avoid obscuring the core points (keep track of a count of nested tags and accumulate data into a list when the recording state is active).

The FailedPreconditionError arises because the program is attempting to read a variable (named "Variable_1") before it has been initialized. In TensorFlow, all variables must be explicitly initialized, by running their "initializer" operations. For convenience, you can run all of the variable initializers in the current session by executing the following statement before your training loop:

tf.initialize_all_variables().run()

Note that this answer assumes that, as in the question, you are using tf.InteractiveSession, which allows you to run operations without specifying a session. For non-interactive uses, it is more common to use tf.Session, and initialize as follows:

init_op = tf.initialize_all_variables()

sess = tf.Session()
sess.run(init_op)

The pattern matching for "gone" in most of the other solutions was a little scary for me. To be safer, this uses the --format flag to pull out each branch's upstream tracking status.

I needed a Windows-friendly version, so this deletes all branches that are listed as "gone" using Powershell:

git branch --list --format "%(if:equals=[gone])%(upstream:track)%(then)%(refname:short)%(end)" | 
    ? { $_ -ne "" } | 
    % { git branch -D $_ }

The first line lists the name of local branches whose upstream branch is "gone". The next line removes blank lines (which are output for branches that aren't "gone"), then the branch name is passed to the command to delete the branch.

What you are trying to do is an extension of string slicing in Python:

Say all strings are of length 10, last char to be removed:

>>> st[:9]
'abcdefghi'

To remove last N characters:

>>> N = 3
>>> st[:-N]
'abcdefg'

To answer the original question:

HTMLDocument doc = new HTMLDocument();
IHTMLDocument2 doc2 = (IHTMLDocument2)doc;
doc2.write(fileText);
// now use doc

Then to convert back to a string:

doc.documentElement.outerHTML;

Here is a possible solution the solution #3 on my comments to blubill's answer:

    $dir = '/home/user/Pictures';
    $file_display = array('jpg', 'jpeg', 'png', 'gif');

    if (file_exists($dir) == false)

        echo 'Directory "', $dir, '" not found!';
    } 
    else 
    {
        $dir_contents = scandir($dir);

        foreach ($dir_contents as $file)

There is also a GUI tool that allows visual JKS creation and certificates importing.

Portecle is a user friendly GUI application for creating, managing and examining keystores, keys, certificates, certificate requests, certificate revocation lists and more.

My approach:

• define a default constraint on the ModDate column with a value of GETDATE() - this handles the INSERT case

• have a AFTER UPDATE trigger to update the ModDate column

Something like:

CREATE TRIGGER trg_UpdateTimeEntry
ON dbo.TimeEntry
AFTER UPDATE
AS
    UPDATE dbo.TimeEntry
    SET ModDate = GETDATE()
    WHERE ID IN (SELECT DISTINCT ID FROM Inserted)

The story of %2F vs / was that, according to the initial W3C recommendations, slashes «must imply a hierarchical structure»:

The slash ("/", ASCII 2F hex) character is reserved for the delimiting of substrings whose relationship is hierarchical. This enables partial forms of the URI.

Example 2

The URIs

http://www.w3.org/albert/bertram/marie-claude

and

http://www.w3.org/albert/bertram%2Fmarie-claude

are NOT identical, as in the second case the encoded slash does not have hierarchical significance.

This is in addition to @phil mccull's accepted answer.

I use his method but I also automate the process by creating a T4 template to be run pre-build.

It all depends on what you want to do, and what you want the derived classes to be able to see.

class A
{
private:
    int _privInt = 0;
    int privFunc(){return 0;}
    virtual int privVirtFunc(){return 0;}
protected:
    int _protInt = 0;
    int protFunc(){return 0;}
public:
    int _publInt = 0;
    int publFunc()
    {
         return privVirtFunc();
    }
};

class B : public A
{
private:
    virtual int privVirtFunc(){return 1;}
public:
    void func()
    {
        _privInt = 1; // wont work
        _protInt = 1; // will work
        _publInt = 1; // will work
        privFunc(); // wont work
        privVirtFunc(); // wont work
        protFunc(); // will work
        publFunc(); // will return 1 since it's overridden in this class

1. Open Vs Code
2. Go to view
3. Click on terminal to open a terminal in VS Code
4. Copy the link for your existing repository from your GitHub page.
5. Type “git clone” and paste the link in addition i.e “git clone https://github.com/...”
6. This will open the repository in your Vs Code Editor.

In addition to the solution with 'aaaaaaaa' LIKE '%' || tag_name || '%' there are position (reversed order of args) and strpos.

SELECT id FROM TAG_TABLE WHERE strpos('aaaaaaaa', tag_name) > 0

Besides what is more efficient (LIKE looks less efficient, but an index might change things), there is a very minor issue with LIKE: tag_name of course should not contain % and especially _ (single char wildcard), to give no false positives.

Technically, it is possible to change the color of anything with CSS. As mentioned, you can't change the background-color or color but you can use CSS filters. For example:

input[type="checkbox"] { /* change "blue" browser chrome to yellow */
  filter: invert(100%) hue-rotate(18deg) brightness(1.7);
}

If you are really looking for design control over checkboxes though, your best bet is to do the "hidden" checkbox and style an adjacent element such as a div.

Just define the target page in the action attribute of the <form> containing the submit button.

So, in page1.jsp:

<form action="page2.jsp">
    <input type="submit">
</form>

Unrelated to the problem, a JSP is not the best place to do business stuff, if you need to do any. Consider learning servlets.

Here is a solutions for MAC PC:

Open terminal and type following command to show hidden files:

defaults write com.apple.finder AppleShowAllFiles YES

after that go to current user folder using finder, then you can see the Library folder in it which is hidden type

suppose in my case the username is 'Delta' so the folder path is:

OS X: ~Delta/Library/Preferences/SmartGit/<main-smartgit-version>

Remove settings file and change option to Non Commercial..

If you want "Socks Proxy", inform the "socksProxyHost" and "socksProxyPort" VM arguments.

e.g.

java -DsocksProxyHost=127.0.0.1 -DsocksProxyPort=8080 org.example.Main

Maybe you'll be able to set the event handlers programmatically, using something like (pseudocode)

sub myhandler(eventsource)
  process(eventsource.value)
end sub

for each cell
  cell.setEventHandler(myHandler)

But i dont know the syntax for achieving this in VB/VBA, or if is even possible.

$("ul").empty() should work and clear the childrens. you can see it here:

http://jsfiddle.net/ZKFA5/

Use the pattern . to match any character once, .* to match any character zero or more times, .+ to match any character one or more times.

for (int i = 0; i < a.length; i++) {
    for (int k = 0; k < a.length; k++) {
        if (a[i] != a[k]) {
            System.out.println(a[i] + " not the same with  " + a[k + 1] + "\n");
        }
    }
}

You can start from k=1 & keep "a.length-1" in outer for loop, in order to reduce two comparisions,but that doesnt make any significant difference.

The issue caused by the docker container which exits as soon as the "start" process finishes. i added a command that runs forever and it worked. This issue mentioned here

var item = (from something in someList
       select x).firstordefault();

Would get the item, and then you could do item.prop1=5; to change the specific property.

Or are you wanting to get a list of items from the db and have it change the property prop1 on each item in that returned list to a specified value? If so you could do this (I'm doing it in VB because I know it better):

dim list = from something in someList select x
for each item in list
    item.prop1=5
next

(list will contain all the items returned with your changes)

Use getDeclaredMethod() to get a private Method object and then use method.setAccessible() to allow to actually call it.

Try:

require(Hmisc)
sapply(name, function(x) {
  paste(sapply(strsplit(x, ' '), capitalize), collapse=' ')
})

As others have stated, if you don't want to save the index column in the first place, you can use df.to_csv('processed.csv', index=False)

However, since the data you will usually use, have some sort of index themselves, let's say a 'timestamp' column, I would keep the index and load the data using it.

So, to save the indexed data, first set their index and then save the DataFrame:

df.set_index('timestamp')
df.to_csv('processed.csv')

Afterwards, you can either read the data with the index:

pd.read_csv('processed.csv', index_col='timestamp')

or read the data, and then set the index:

pd.read_csv('filename.csv')
pd.set_index('column_name')

See How to: Determine Which .NET Framework Versions Are Installed (MSDN).

MSDN proposes one function example that seems to do the job for version 1-4. According to the article, the method output is:

v2.0.50727  2.0.50727.4016  SP2
v3.0  3.0.30729.4037  SP2
v3.5  3.5.30729.01  SP1
v4
  Client  4.0.30319
  Full  4.0.30319

Note that for "versions 4.5 and later" there is another function.

Use this code with a closure (introduced in PHP 5.3), it's a bit faster than the accepted answer and for me, the intention to cast it to an integer, is clearer:

// if you have your values in the format '1,2,3,4', use this before:
// $stringArray = explode(',', '1,2,3,4');

$stringArray = ['1', '2', '3', '4'];

$intArray = array_map(
    function($value) { return (int)$value; },
    $stringArray
);

var_dump($intArray);

Output will be:

array(4) {
  [0]=>
  int(1)
  [1]=>
  int(2)
  [2]=>
  int(3)
  [3]=>
  int(4)
}

What is it exactly?

An FCM Token, or much commonly known as a registrationToken like in google-cloud-messaging. As described in the GCM FCM docs:

An ID issued by the GCM connection servers to the client app that allows it to receive messages. Note that registration tokens must be kept secret.

How can I get that token?

Update: The token can still be retrieved by calling getToken(), however, as per FCM's latest version, the FirebaseInstanceIdService.onTokenRefresh() has been replaced with FirebaseMessagingService.onNewToken() -- which in my experience functions the same way as onTokenRefresh() did.

Old answer:

As per the FCM docs:

On initial startup of your app, the FCM SDK generates a registration token for the client app instance. If you want to target single devices or create device groups, you'll need to access this token.

You can access the token's value by extending FirebaseInstanceIdService. Make sure you have added the service to your manifest, then call getToken in the context of onTokenRefresh, and log the value as shown:

@Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    Log.d(TAG, "Refreshed token: " + refreshedToken);

    // TODO: Implement this method to send any registration to your app's servers.
    sendRegistrationToServer(refreshedToken);
}

The onTokenRefreshcallback fires whenever a new token is generated, so calling getToken in its context ensures that you are accessing a current, available registration token. FirebaseInstanceID.getToken() returns null if the token has not yet been generated.

After you've obtained the token, you can send it to your app server and store it using your preferred method. See the Instance ID API reference for full detail on the API.

From the manual: The SELECT ... INTO OUTFILE statement is intended primarily to let you very quickly dump a table to a text file on the server machine. If you want to create the resulting file on some client host other than the server host, you cannot use SELECT ... INTO OUTFILE. In that case, you should instead use a command such as mysql -e "SELECT ..." > file_name to generate the file on the client host."

http://dev.mysql.com/doc/refman/5.0/en/select.html

An example:

mysql -h my.db.com -u usrname--password=pass db_name -e 'SELECT foo FROM bar' > /tmp/myfile.txt

How to properly -filter multiple strings in a PowerShell copy script

You have to use -Include flag for Get-ChildItem

My Example:

$Location = "C:\user\files" 
$result = (Get-ChildItem $Location\* -Include *.png, *.gif, *.jpg)

Dont forget put "*" after path location.

If you are using SQL Server 2016 or newer, you can also select it as JSON result and display it in JSON Visualizer, it's much easier to read it than in XML and allows you to filter results.

DECLARE @v nvarchar(max) = (SELECT * FROM Suppliers FOR JSON AUTO)

currently reopquery is integrated into dnf and yum, so typing:

dnf repoquery -l <pkg-name>

will list package contents from a remote repository (even for the packages that are not installed yet)

meaning installing a separate dnf-utils or yum-utils package is no longer required for the functionality as it is now being supported natively.

for listing installed or local (*.rpm files) packages' contents there is rpm -ql

i don't think it is possible with yum org dnf (not repoquery subcommand)

With the upcoming release of iOS 7 you will notice that the "standard" icon radius has been increased. So try to do what Apple and I suggested with this answer.

It appears that for a 120px icon the formula that best represents its shape on iOS 7 is the following superellipse:

|x/120|^5 + |y/120|^5 = 1

Obviously you can change the 120 number with the desired icon size to get the corresponding function.

Original

You should provide an image that has 90° corners (it’s important to avoid cropping the corners of your icon—iOS does that for you when it applies the corner-rounding mask) (Apple Documentation)

The best approach is not rounding the corners of your icons at all. If you set your icon as a square icon, iOS will automatically overlay the icon with a predefined mask that will set the appropriate rounded corners.

If you manually set rounded corners for your icons, they will probably look broken in this or that device, because the rounding mask happens to slightly change from an iOS version to another. Sometimes your icons will be slightly larger, sometimes (sigh) slightly smaller. Using a square icon will free you from this burden, and you will be sure to have an always up-to-date and good looking icon for your app.

This approach is valid for each icon size (iPhone/iPod/iPad/retina), and also for the iTunes artwork. I followed this approach a couple of times, and if you want I can post you a link to an app that uses native square icons.

Edit

To better understand this answer, please refer to the official Apple documentation about iOS icons. In this page it is clearly stated that a square icon will automatically get these things when displayed on an iOS device:

1. Rounded corners
2. Drop shadow
3. Reflective shine (unless you prevent the shine effect)

So, you can achieve whatever effect you want just drawing a plain square icon and filling content in it. The final corner radius will be something similar to what the other answers here are saying, but this will never be guaranteed, since those numbers are not part of the official Apple documentation on iOS. They ask you to draw square icons, so ... why not?

Like this:

<c:forEach var="entry" items="${myMap}">
  Key: <c:out value="${entry.key}"/>
  Value: <c:out value="${entry.value}"/>
</c:forEach>

Most probably you won't be able to read Word documents without COM.

Writing was covered in this topic

My 10 cents contribution.

I still have this problem occasionally on VS 2015 Update 2.

I found that switching compilation target solves the problem.

Try this: if you are in DEBUG switch to RELEASE and build, then back to DEBUG. The problem is gone.

If you are staying in vanilla Javascript, please note keyCode is now deprecated and will be dropped:

This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Avoid using it and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any tim

https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/keyCode

Instead use either: .key or .code depending on what behavior you want: https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/code https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key

Both are implemented on modern browsers.

This is what I'm using to get the running jobs (principally so I can kill the ones which have probably hung):

SELECT
    job.Name, job.job_ID
    ,job.Originating_Server
    ,activity.run_requested_Date
    ,datediff(minute, activity.run_requested_Date, getdate()) AS Elapsed
FROM
    msdb.dbo.sysjobs_view job 
        INNER JOIN msdb.dbo.sysjobactivity activity
        ON (job.job_id = activity.job_id)
WHERE
    run_Requested_date is not null 
    AND stop_execution_date is null
    AND job.name like 'Your Job Prefix%'

As Tim said, the MSDN / BOL documentation is reasonably good on the contents of the sysjobsX tables. Just remember they are tables in MSDB.

Nested with statements will do the same job, and in my opinion, are more straightforward to deal with.

Let's say you have inFile.txt, and want to write it into two outFile's simultaneously.

with open("inFile.txt", 'r') as fr:
    with open("outFile1.txt", 'w') as fw1:
        with open("outFile2.txt", 'w') as fw2:
            for line in fr.readlines():
                fw1.writelines(line)
                fw2.writelines(line)

EDIT:

I don't understand the reason of the downvote. I tested my code before publishing my answer, and it works as desired: It writes to all of outFile's, just as the question asks. No duplicate writing or failing to write. So I am really curious to know why my answer is considered to be wrong, suboptimal or anything like that.

In the term of SEO , 301 and 302 both are good it is depend on situation,

If only one version can be returned (i.e., the other redirects to it), that’s great! This behavior is beneficial because it reduces duplicate content. In the particular case of redirects to trailing slash URLs, our search results will likely show the version of the URL with the 200 response code (most often the trailing slash URL) -- regardless of whether the redirect was a 301 or 302.

Bootstrap has predefined classes that we use for styling. If you are familiar with CSS, you'd know what padding, margin and spacing etc. are.

mb-0 = margin-bottom:0;

OK now moving a little further in knowledge, bootstrap has more classes for margin including:

mt- = margin-top
mb- = margin-bottom
ml- = margin-left
mr- = margin-right
my- = it sets margin-left and margin-right at the same time on y axes
mX- = it sets margin-bottom and margin-top at the same time on X axes

This and much more is explained here https://getbootstrap.com/docs/5.0/utilities/spacing/ The best way to learn is through https://getbootstrap.com site itself. It explains a lot obout its built in classes.

Bind & protected-mode both are the essential steps. But if ufw is enabled then you will have to make redis port allow in ufw.

1. Check ufw status ufw status if Status: active then allow redis-port ufw allow 6379
2. vi /etc/redis/redis.conf
3. Change the bind 127.0.0.1 to bind 0.0.0.0
4. change the protected-mode yes to protected-mode no

If you are using Swift, the Just library does this for you. Example from it's readme file:

//  talk to registration end point
Just.post(
    "http://justiceleauge.org/member/register",
    data: ["username": "barryallen", "password":"ReverseF1ashSucks"],
    files: ["profile_photo": .URL(fileURLWithPath:"flash.jpeg", nil)]
) { (r)
    if (r.ok) { /* success! */ }
}

You don't need jQuery for that. Use regular javascript

var arr = new Array();
// or var arr = [];
arr.push('value1');
arr.push('value2');

Note: In javascript, you can also use Objects as Arrays, but still have access to the Array prototypes. This makes the object behave like an array:

var obj = new Object();
Array.prototype.push.call(obj, 'value');

will create an object that looks like:

{
    0: 'value',
    length: 1
}

You can access the vaules just like a normal array f.ex obj[0].

Node is complaining because there is no function called define, which your code tries to call on its very first line.

define comes from AMD, which is not used in standard node development.

It is possible that the developer you got your project from used some kind of trickery to use AMD in node. You should ask this person what special steps are necessary to run the code.

This has been reverse-engineered by Pierre87 on the FrAndroid forum, but I can't find anywhere official that describes it, so it's has to be treated as undocumented and liable to stop working at any moment:

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setClassName("com.facebook.katana", "com.facebook.katana.ProfileTabHostActivity");
intent.putExtra("extra_user_id", "123456789l");
this.startActivity(intent);

I know that I'm not answering the xargs question directly but it's worth mentioning find's -exec option.

Given the following file system:

[root@localhost bokeh]# tree --charset assci bands
bands
|-- Dream\ Theater
|-- King's\ X
|-- Megadeth
`-- Rush

0 directories, 4 files

The find command can be made to handle the space in Dream Theater and King's X. So, to find the drummers of each band using grep:

[root@localhost]# find bands/ -type f -exec grep Drums {} +
bands/Dream Theater:Drums:Mike Mangini
bands/Rush:Drums: Neil Peart
bands/King's X:Drums:Jerry Gaskill
bands/Megadeth:Drums:Dirk Verbeuren

In the -exec option {} stands for the filename including path. Note that you don't have to escape it or put it in quotes.

The difference between -exec's terminators (+ and \;) is that + groups as many file names that it can onto one command line. Whereas \; will execute the command for each file name.

So, find bands/ -type f -exec grep Drums {} + will result in:

grep Drums "bands/Dream Theater" "bands/Rush" "bands/King's X" "bands/Megadeth"

and find bands/ -type f -exec grep Drums {} \; will result in:

grep Drums "bands/Dream Theater"
grep Drums "bands/Rush"
grep Drums "bands/King's X"
grep Drums "bands/Megadeth"

In the case of grep this has the side effect of either printing the filename or not.

[root@localhost bokeh]# find bands/ -type f -exec grep Drums {} \;
Drums:Mike Mangini
Drums: Neil Peart
Drums:Jerry Gaskill
Drums:Dirk Verbeuren

[root@localhost bokeh]# find bands/ -type f -exec grep Drums {} +
bands/Dream Theater:Drums:Mike Mangini
bands/Rush:Drums: Neil Peart
bands/King's X:Drums:Jerry Gaskill
bands/Megadeth:Drums:Dirk Verbeuren

Of course, grep's options -h and -H will control whether or not the filename is printed regardless of how grep is called.

xargs

xargs can also control how man files are on the command line.

xargs by default groups all the arguments onto one line. In order to do the same thing that -exec \; does use xargs -l. Note that the -t option tells xargs to print the command before executing it.

[root@localhost bokeh]# find ./bands -type f  | xargs -d '\n' -l -t grep Drums
grep Drums ./bands/Dream Theater 
Drums:Mike Mangini
grep Drums ./bands/Rush 
Drums: Neil Peart
grep Drums ./bands/King's X 
Drums:Jerry Gaskill
grep Drums ./bands/Megadeth 
Drums:Dirk Verbeuren

See that the -l option tells xargs to execute grep for every filename.

Versus the default (i.e. no -l option):

[root@localhost bokeh]# find ./bands -type f  | xargs -d '\n'  -t grep Drums
grep Drums ./bands/Dream Theater ./bands/Rush ./bands/King's X ./bands/Megadeth 
./bands/Dream Theater:Drums:Mike Mangini
./bands/Rush:Drums: Neil Peart
./bands/King's X:Drums:Jerry Gaskill
./bands/Megadeth:Drums:Dirk Verbeuren

xargs has better control on how many files can be on the command line. Give the -l option the max number of files per command.

[root@localhost bokeh]# find ./bands -type f  | xargs -d '\n'  -l2 -t grep Drums
grep Drums ./bands/Dream Theater ./bands/Rush 
./bands/Dream Theater:Drums:Mike Mangini
./bands/Rush:Drums: Neil Peart
grep Drums ./bands/King's X ./bands/Megadeth 
./bands/King's X:Drums:Jerry Gaskill
./bands/Megadeth:Drums:Dirk Verbeuren
[root@localhost bokeh]# 

See that grep was executed with two filenames because of -l2.

You can use Marcus's answer (* wildcards) outside a case statement, too, if you use double brackets:

string='My long string'
if [[ $string == *"My long"* ]]; then
  echo "It's there!"
fi

Note that spaces in the needle string need to be placed between double quotes, and the * wildcards should be outside. Also note that a simple comparison operator is used (i.e. ==), not the regex operator =~.

void p(String l){
System.out.println(l);
}

Shortest. Go for it.

I had the same requirements to create a kind of step progress tracker so I created a JavaScript plugin for that purpose. Here is the JsFiddle for the demo for this step progress tracker. You can access its code on GitHub as well.

What it basically does is, it takes the json data(in a particular format described below) as input and creates the progress tracker based on that. Highlighted steps indicates the completed steps.

It's html will somewhat look like shown below with default CSS but you can customize it as per the theme of your application. There is an option to show tool-tip text for each steps as well.

Here is some code snippet for that:

//container div 
<div id="tracker1" style="width: 700px">
</div>

//sample JSON data
var sampleJson1 = {
ToolTipPosition: "bottom",
data: [{ order: 1, Text: "Foo", ToolTipText: "Step1-Foo", highlighted: true },
    { order: 2, Text: "Bar", ToolTipText: "Step2-Bar", highlighted: true },
    { order: 3, Text: "Baz", ToolTipText: "Step3-Baz", highlighted: false },
    { order: 4, Text: "Quux", ToolTipText: "Step4-Quux", highlighted: false }]
};    

//Invoking the plugin
$(document).ready(function () {
        $("#tracker1").progressTracker(sampleJson1);
    });

Hopefully it will be useful for somebody else as well!

If the variable can only ever take on boolean values, then it's reasonable to use the shorter syntax.

If it can potentially be assigned other types, and you need to distinguish true from 1 or "foo", then you must use === true.

There are different ways for this:

1.Building C# Applications Using csc.exe

While it is true that you might never decide to build a large-scale application using nothing but the C# command-line compiler, it is important to understand the basics of how to compile your code files by hand.

2.Building .NET Applications Using Notepad++

Another simple text editor I’d like to quickly point out is the freely downloadable Notepad++ application. This tool can be obtained from http://notepad-plus.sourceforge.net. Unlike the primitive Windows Notepad application, Notepad++ allows you to author code in a variety of languages and supports

3.Building .NET Applications Using SharpDevelop

As you might agree, authoring C# code with Notepad++ is a step in the right direction, compared to Notepad. However, these tools do not provide rich IntelliSense capabilities for C# code, designers for building graphical user interfaces, project templates, or database manipulation utilities. To address such needs, allow me to introduce the next .NET development option: SharpDevelop (also known as "#Develop").You can download it from http://www.sharpdevelop.com.

I was running into this error while converting from nvarchar to float.
What I had to do was to use the LEFT function on the nvarchar field.

Example: Left(Field,4)

Basically, the query will look like:

Select convert(float,left(Field,4)) from TABLE

Just ridiculous that SQL would complicate it to this extent, while with C# it's a breeze!
Hope it helps someone out there.

function listselect() {
                var selected = [];
                $('.SelectPhone').prop('checked', function () {

                    selected.push($(this).val());
                });

                alert(selected.length);

     <input type="checkbox" name="SelectPhone" class="SelectPhone"  value="1" />
         <input type="checkbox" name="SelectPhone" class="SelectPhone"  value="2" />
         <input type="checkbox" name="SelectPhone" class="SelectPhone"  value="3" />
        <button onclick="listselect()">show count</button>

here's a simple one

    private boolean isFirst = true;
private void setAdapter() {
    final ArrayList<String> spinnerArray = new ArrayList<String>();     
    spinnerArray.add("Select your option");
    spinnerArray.add("Option 1");
    spinnerArray.add("Option 2");
    spin.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
            TextView tv = (TextView)selectedItemView;
            String res = tv.getText().toString().trim();
            if (res.equals("Option 1")) {
            //do Something
        } else if (res.equals("Option 2")) {
            //do Something else
        }
        }

        @Override
        public void onNothingSelected(AdapterView<?> parentView) { }

    });

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.my_spinner_style,spinnerArray) {
         public View getView(int position, View convertView, ViewGroup parent) {
             View v = super.getView(position, convertView, parent);
             int height = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 25, getResources().getDisplayMetrics());                  
             ((TextView) v).setTypeface(tf2);
             ((TextView) v).getLayoutParams().height = height;
             ((TextView) v).setGravity(Gravity.CENTER);
             ((TextView) v).setTextSize(TypedValue.COMPLEX_UNIT_SP, 19);
             ((TextView) v).setTextColor(Color.WHITE);
             return v;
         }

         public View getDropDownView(int position, View convertView,
                 ViewGroup parent) {
             if (isFirst) {
                 isFirst = false;
                 spinnerArray.remove(0);
             }
             View v = super.getDropDownView(position, convertView, parent);                  
             ((TextView) v).setTextColor(Color.argb(255, 70, 70, 70));
             ((TextView) v).setTypeface(tf2);
             ((TextView) v).setGravity(Gravity.CENTER);
             return v;
         }
     };
     spin.setAdapter(adapter);
}

Ignoring the smooth interpolation between points in your example graph (that would require doing some manual interpolation, or just have a higher resolution of your data), you can use pyplot.fill_between():

from matplotlib import pyplot as plt
import numpy as np

x = np.linspace(0, 30, 30)
y = np.sin(x/6*np.pi)
error = np.random.normal(0.1, 0.02, size=y.shape)
y += np.random.normal(0, 0.1, size=y.shape)

plt.plot(x, y, 'k-')
plt.fill_between(x, y-error, y+error)
plt.show()

See also the matplotlib examples.

I faced the same problem today. You need to enable the intl PHP extension in your PHP configuration (.ini).

Solution Xampp (Windows)

1. Open /xampp/php/php.ini
2. Change ;extension=php_intl.dll to extension=php_intl.dll (remove the semicolon)
3. Copy all the /xampp/php/ic*.dll files to /xampp/apache/bin
4. Restart apache in the Xampp control panel

Solution Linux (thanks to Annamalai Somasundaram)

1. Install the php5-intl extension sudo apt-get install php5-intl

   1.1. Alternatively use sudo yum install php5-intl if you are on CentOS or Fedora.

2. Restart apache sudo service apache2 restart

Solution Mac/OSX (homebrew) (thanks to deizel)

1. Install the php5-intl extension brew install php56-intl
2. If you get No available formula for php56-intl follow these instructions.
3. Restart apache sudo apachectl restart

Eventually you can run composer install to check if it's working. It will give an error if it's not.

I found that the answer by cballou was no longer working in Firefox as of Jan. 2014. Specifically, if (self.pageYOffset) didn't trigger if the client had scrolled right, but not down - because 0 is a falsey number. This went undetected for a while because Firefox supported document.body.scrollLeft/Top, but this is no longer working for me (on Firefox 26.0).

Here's my modified solution:

var getPageScroll = function(document_el, window_el) {
  var xScroll = 0, yScroll = 0;
  if (window_el.pageYOffset !== undefined) {
    yScroll = window_el.pageYOffset;
    xScroll = window_el.pageXOffset;
  } else if (document_el.documentElement !== undefined && document_el.documentElement.scrollTop) {
    yScroll = document_el.documentElement.scrollTop;
    xScroll = document_el.documentElement.scrollLeft;
  } else if (document_el.body !== undefined) {// all other Explorers
    yScroll = document_el.body.scrollTop;
    xScroll = document_el.body.scrollLeft;
  }
  return [xScroll,yScroll];
};

Tested and working in FF26, Chrome 31, IE11. Almost certainly works on older versions of all of them.

Firebug debug process

Array initializer support for type inference were changed in Visual Basic 10 vs Visual Basic 9.

In previous version of VB it was required to put empty parens to signify an array. Also, it would define the array as object array unless otherwise was stated:

' Integer array
Dim i as Integer() = {1, 2, 3, 4} 

' Object array
Dim o() = {1, 2, 3} 

Check more info:

For .NET Core 2.0, you can simply:

Declare your key/value pairs in appsettings.json:

{
  "MyKey": "MyValue"
}

Inject the configuration service in startup.cs, and get the value using the service

using Microsoft.Extensions.Configuration;

public class Startup
{
    public void Configure(IConfiguration configuration,
                          ... other injected services
                          )
    {
        app.Run(async (context) =>
        {
            string myValue = configuration["MyKey"];
            await context.Response.WriteAsync(myValue);
        });

AddressSanitizer (ASan) is a fast memory error detector. It finds use-after-free and {heap,stack,global}-buffer overflow bugs in C/C++ programs. It finds:

• Use after free (dangling pointer dereference)
• Heap buffer overflow
• Stack buffer overflow
• Global buffer overflow
• Use after return
• Initialization order bugs

This tool is very fast. The average slowdown of the instrumented program is ~2x.

You need to set ulimit -c. If you have 0 for this parameter a coredump file is not created. So do this: ulimit -c unlimited and check if everything is correct ulimit -a. The coredump file is created when an application has done for example something inappropriate. The name of the file on my system is core.<process-pid-here>.

I don't think adb pull handles wildcards for multiple files. I ran into the same problem and did this by moving the files to a folder and then pulling the folder.

I found a link doing the same thing. Try following these steps.

As shown in the image attached:

The simplest way is just adding a transparent border to the div that contains the image and setting its display property to inline-block just like this:

CSS:

div{
margin: 2rem;
height: 100vh;
overflow: hidden;
display: inline-block;
border: 1px solid #00000000;
}

img {
-webkit-filter: blur(2rem);
filter: blur(2rem);
}

Here's a codepen depicting the same: https://codepen.io/arnavozil/pen/ExPYKNZ

Since PostgreSQL 9.1 there is the convenient FOREACH:

DO
$do$
DECLARE
   m   varchar[];
   arr varchar[] := array[['key1','val1'],['key2','val2']];
BEGIN
   FOREACH m SLICE 1 IN ARRAY arr
   LOOP
      RAISE NOTICE 'another_func(%,%)',m[1], m[2];
   END LOOP;
END
$do$

Solution for older versions:

DO
$do$
DECLARE
   arr varchar[] := '{{key1,val1},{key2,val2}}';
BEGIN
   FOR i IN array_lower(arr, 1) .. array_upper(arr, 1)
   LOOP
      RAISE NOTICE 'another_func(%,%)',arr[i][1], arr[i][2];
   END LOOP;
END
$do$

Also, there is no difference between varchar[] and varchar[][] for the PostgreSQL type system. I explain in more detail here.

The DO statement requires at least PostgreSQL 9.0, and LANGUAGE plpgsql is the default (so you can omit the declaration).

The differences are covered at the PostgreSQL documentation for date/time types. Yes, the treatment of TIME or TIMESTAMP differs between one WITH TIME ZONE or WITHOUT TIME ZONE. It doesn't affect how the values are stored; it affects how they are interpreted.

The effects of time zones on these data types is covered specifically in the docs. The difference arises from what the system can reasonably know about the value:

• With a time zone as part of the value, the value can be rendered as a local time in the client.

• Without a time zone as part of the value, the obvious default time zone is UTC, so it is rendered for that time zone.

The behaviour differs depending on at least three factors:

• The timezone setting in the client.
• The data type (i.e. WITH TIME ZONE or WITHOUT TIME ZONE) of the value.
• Whether the value is specified with a particular time zone.

Here are examples covering the combinations of those factors:

foo=> SET TIMEZONE TO 'Japan';
SET
foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP;
      timestamp      
---------------------
 2011-01-01 00:00:00
(1 row)

foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP WITH TIME ZONE;
      timestamptz       
------------------------
 2011-01-01 00:00:00+09
(1 row)

foo=> SELECT '2011-01-01 00:00:00+03'::TIMESTAMP;
      timestamp      
---------------------
 2011-01-01 00:00:00
(1 row)

foo=> SELECT '2011-01-01 00:00:00+03'::TIMESTAMP WITH TIME ZONE;
      timestamptz       
------------------------
 2011-01-01 06:00:00+09
(1 row)

foo=> SET TIMEZONE TO 'Australia/Melbourne';
SET
foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP;
      timestamp      
---------------------
 2011-01-01 00:00:00
(1 row)

foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP WITH TIME ZONE;
      timestamptz       
------------------------
 2011-01-01 00:00:00+11
(1 row)

foo=> SELECT '2011-01-01 00:00:00+03'::TIMESTAMP;
      timestamp      
---------------------
 2011-01-01 00:00:00
(1 row)

foo=> SELECT '2011-01-01 00:00:00+03'::TIMESTAMP WITH TIME ZONE;
      timestamptz

To change the remote upstream: git remote set-url origin <url>

To add more upstreams: git remote add newplace <url>

So you can choose where to work git push origin <branch> or git push newplace <branch>

I'm guessing that you want something like

SELECT tab1.a, tab2.b, tab3.c, tab4.d
  FROM table1 tab1 
       JOIN table2 tab2 ON (tab1.fg = tab2.fg)
       LEFT OUTER JOIN table4 tab4 ON (tab1.ss = tab4.ss)
       LEFT OUTER JOIN table3 tab3 ON (tab4.xya = tab3.xya and tab3.desc = 'XYZ')
       LEFT OUTER JOIN table5 tab5 on (tab4.kk = tab5.kk AND
                                       tab3.dd = tab5.dd)

Use the "import android.app.AlertDialog;" import and then you write

    String[] items = {"...","...."};             
    AlertDialog.Builder build = new AlertDialog.Builder(context);
    build.setItems(items, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            //do stuff....
        }
    }).create().show();

I am late, but a simple list slicing will do the work

today_date = date.today().strftime('%d %b %Y')
if today_date[0] == '0':
    today_date = today_date[1:]

A possible way to achieve this is the following.

if (!Object.prototype.merge){
    Object.prototype.merge = function(obj){
        var self = this;
        Object.keys(obj).forEach(function(key){
            self[key] = obj[key]
        });
    }
};

I don't know if it's better then the other answers. In this method you add the merge function to Objects prototype. This way you can call obj1.merge(obj2);

Note : you should validate your argument to see if its an object and 'throw' a proper Error. If not Object.keys will 'throw' an 'Error'

var yearStart = 2000;
var yearEnd = 2040;

var arr = [];

for (var i = yearStart; i <= yearEnd; i++) {

     arr.push(i);
}

Of course the answers above all do the job, but still i would like to use something like

gradle run path1 path2

well this can't be done, but what if we can:

gralde run --- path1 path2

If you think it is more elegant, then you can do it, the trick is to process the command line and modify it before gradle does, this can be done by using init scripts

The init script below:

1. Process the command line and remove --- and all other arguments following '---'
2. Add property 'appArgs' to gradle.ext

So in your run task (or JavaExec, Exec) you can:

if (project.gradle.hasProperty("appArgs")) {
                List<String> appArgs = project.gradle.appArgs;

                args appArgs

 }

The init script is:

import org.gradle.api.invocation.Gradle

Gradle aGradle = gradle

StartParameter startParameter = aGradle.startParameter

List tasks = startParameter.getTaskRequests();

List<String> appArgs = new ArrayList<>()

tasks.forEach {
   List<String> args = it.getArgs();


   Iterator<String> argsI = args.iterator();

   while (argsI.hasNext()) {

      String arg = argsI.next();

      // remove '---' and all that follow
      if (arg == "---") {
         argsI.remove();

         while (argsI.hasNext()) {

            arg = argsI.next();

            // and add it to appArgs
            appArgs.add(arg);

            argsI.remove();

        }
    }
}

}


   aGradle.ext.appArgs = appArgs

Limitations:

1. I was forced to use '---' and not '--'
2. You have to add some global init script

If you don't like global init script, you can specify it in command line

gradle -I init.gradle run --- f:/temp/x.xml

Or better add an alias to your shell:

gradleapp run --- f:/temp/x.xml

# Original code
df = pd.DataFrame({'a': [1, 2, 3, 'bad', 5],
                   'b': [0.1, 0.2, 0.3, 0.4, 0.5],
                   'item': ['a', 'b', 'c', 'd', 'e']})
df = df.set_index('item')

Convert to numeric using 'coerce' which fills bad values with 'nan'

a = pd.to_numeric(df.a, errors='coerce')

Use isna to return a boolean index:

idx = a.isna()

Apply that index to the data frame:

df[idx]

output

Returns the row with the bad data in it:

        a    b
item          
d     bad  0.4

@kit's answer is okay, but remember to add ROUTER_PROVIDERS to providers in the component. Then you can redirect to another page within ngOnInit method:

import {Component, OnInit} from 'angular2/core';
import {Router, ROUTER_PROVIDERS} from 'angular2/router'

@Component({
    selector: 'loginForm',
    templateUrl: 'login.html',
    providers: [ROUTER_PROVIDERS]
})

export class LoginComponent implements OnInit {

    constructor(private router: Router) { }

    ngOnInit() {
        this.router.navigate(['./SomewhereElse']);
    }

}

.clearfix is defined in less/mixins.less. Right above its definition is a comment with a link to this article:

A new micro clearfix hack

The article explains how it all works.

UPDATE: Yes, link-only answers are bad. I knew this even at the time that I posted this answer, but I didn't feel like copying and pasting was OK due to copyright, plagiarism, and what have you. However, I now feel like it's OK since I have linked to the original article. I should also mention the author's name, though, for credit: Nicolas Gallagher. Here is the meat of the article (note that "Thierry’s method" is referring to Thierry Koblentz’s “clearfix reloaded”):

This “micro clearfix” generates pseudo-elements and sets their display to table. This creates an anonymous table-cell and a new block formatting context that means the :before pseudo-element prevents top-margin collapse. The :after pseudo-element is used to clear the floats. As a result, there is no need to hide any generated content and the total amount of code needed is reduced.

Including the :before selector is not necessary to clear the floats, but it prevents top-margins from collapsing in modern browsers. This has two benefits:

• It ensures visual consistency with other float containment techniques that create a new block formatting context, e.g., overflow:hidden

• It ensures visual consistency with IE 6/7 when zoom:1 is applied.

N.B.: There are circumstances in which IE 6/7 will not contain the bottom margins of floats within a new block formatting context. Further details can be found here: Better float containment in IE using CSS expressions.

The use of content:" " (note the space in the content string) avoids an Opera bug that creates space around clearfixed elements if the contenteditable attribute is also present somewhere in the HTML. Thanks to Sergio Cerrutti for spotting this fix. An alternative fix is to use font:0/0 a.

Legacy Firefox

Firefox < 3.5 will benefit from using Thierry’s method with the addition of visibility:hidden to hide the inserted character. This is because legacy versions of Firefox need content:"." to avoid extra space appearing between the body and its first child element, in certain circumstances (e.g., jsfiddle.net/necolas/K538S/.)

Alternative float-containment methods that create a new block formatting context, such as applying overflow:hidden or display:inline-block to the container element, will also avoid this behaviour in legacy versions of Firefox.

This error was generated for me by having an incorrectly formatted NLog.config file.

Start your activity with request code :

StartActivityForResult(intent,1234);

And you can close it from any other activity like this :

finishActivity(1234);

You can't do it with pure PHP. You must do it with JavaScript. There are several articles written on how to do this.

Essentially, you can set a cookie or you can even do some Ajax to send the info to a PHP script. If you use jQuery, you can do it something like this:

jquery:

$(function() {
    $.post('some_script.php', { width: screen.width, height:screen.height }, function(json) {
        if(json.outcome == 'success') {
            // do something with the knowledge possibly?
        } else {
            alert('Unable to let PHP know what the screen resolution is!');
        }
    },'json');
});

PHP (some_script.php)

<?php
// For instance, you can do something like this:
if(isset($_POST['width']) && isset($_POST['height'])) {
    $_SESSION['screen_width'] = $_POST['width'];
    $_SESSION['screen_height'] = $_POST['height'];
    echo json_encode(array('outcome'=>'success'));
} else {
    echo json_encode(array('outcome'=>'error','error'=>"Couldn't save dimension info"));
}
?>

All that is really basic but it should get you somewhere. Normally screen resolution is not what you really want though. You may be more interested in the size of the actual browser's view port since that is actually where the page is rendered...

The main scenario where JAX-WS RPC and Document style are used as follows:

• The Remote Procedure Call (RPC) pattern is used when the consumer views the web service as a single logical application or component with encapsulated data. The request and response messages map directly to the input and output parameters of the procedure call.

  Examples of this type the RPC pattern might include a payment service or a stock quote service.

• The document-based pattern is used in situations where the consumer views the web service as a longer running business process where the request document represents a complete unit of information. This type of web service may involve human interaction for example as with a credit application request document with a response document containing bids from lending institutions. Because longer running business processes may not be able to return the requested document immediately, the document-based pattern is more commonly found in asynchronous communication architectures. The Document/literal variation of SOAP is used to implement the document-based web service pattern.

Run these codes in thread or AsyncTask. In order to avoid duplicated callings of same _url(one time for getContentLength(), one time of openStream()), use IOUtils.toByteArray of Apache.

void downloadFile(String _url, String _name) {
    try {
        URL u = new URL(_url);
        DataInputStream stream = new DataInputStream(u.openStream());
        byte[] buffer = IOUtils.toByteArray(stream);
        FileOutputStream fos = mContext.openFileOutput(_name, Context.MODE_PRIVATE);
        fos.write(buffer);
        fos.flush();
        fos.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
        return;
    } catch (IOException e) {
        e.printStackTrace();
        return;
    }
}

My team moved away from Bower and migrated to npm because:

• Programmatic usage was painful
• Bower's interface kept changing
• Some features, like the url shorthand, are entirely broken
• Using both Bower and npm in the same project is painful
• Keeping bower.json version field in sync with git tags is painful
• Source control != package management
• CommonJS support is not straightforward

For more details, see "Why my team uses npm instead of bower".

I don't have enough rep to put this under comments to the existing answers:

unescape is only deprecated for working with URIs (or any encoded utf-8) which is probably the case for most people's needs. encodeURIComponent converts a js string to escaped UTF-8 and decodeURIComponent only works on escaped UTF-8 bytes. It throws an error for something like decodeURIComponent('%a9'); // error because extended ascii isn't valid utf-8 (even though that's still a unicode value), whereas unescape('%a9'); // © So you need to know your data when using decodeURIComponent.

decodeURIComponent won't work on "%C2" or any lone byte over 0x7f because in utf-8 that indicates part of a surrogate. However decodeURIComponent("%C2%A9") //gives you © Unescape wouldn't work properly on that // © AND it wouldn't throw an error, so unescape can lead to buggy code if you don't know your data.

If you do not want to configure the message converters yourself, you can use either @EnableWebMvc or <mvc:annotation-driven />, add Jackson to the classpath and Spring will give you both JSON, XML (and a few other converters) by default. Additionally, you will get some other commonly used features for conversion, formatting and validation.

grep's -A 1 option will give you one line after; -B 1 will give you one line before; and -C 1 combines both to give you one line both before and after, -1 does the same.

I am using visual studio 2010 to make a program on SMSC Server. What you have to do is go to build-->publish. you will be asked be asked to few simple things and the location where you want to store your application, browse the location where you want to put it.

I hope this is what you are looking for

The syntax a if b else c is a ternary operator in Python that evaluates to a if the condition b is true - otherwise, it evaluates to c. It can be used in comprehension statements:

>>> [a if a else 2 for a in [0,1,0,3]]
[2, 1, 2, 3]

So for your example,

table = ''.join(chr(index) if index in ords_to_keep else replace_with
                for index in xrange(15))

DateTime values in T-SQL are stored as floats. You can just subtract the dates from each other and you now have a new date that is the timespan between them.

declare @birthdate datetime
set @birthdate = '6/15/1974'

--age in years - short version
print year(getdate() - @birthdate) - year(0)

--age in years - visualization
declare @mindate datetime
declare @span datetime

set @mindate = 0
set @span = getdate() - @birthdate

print @mindate
print @birthdate
print getdate()
print @span
--substract minyear from spanyear to get age in years
print year(@span) - year(@mindate)
print month(@span)
print day(@span)

yes, sql server doesn't allow to insert single quote in table field due to the sql injection attack. so we must replace single appostrophe by double while saving.

I would just use the FindAll method on the List class. i.e.:

List<Person> filteredResults = 
    people.FindAll(p => return !exclusions.Contains(p));

Not sure if the syntax will exactly match your objects, but I think you can see where I'm going with this.

One way to do it is to use flexbox in order to align the text on the middle. The way I found to do it, is the following:

HTML:

<div class="circle-without-text">
  <div class="text-inside-circle">
    The text
  </div>
</div>

CSS:

.circle-without-text {
    border-radius: 50%;
    width: 70vh;
    height: 70vh;
    background-color: red;
    position: relative;
 }

.text-inside-circle {
    position: absolute;
    top: 0;
    bottom: 0;
    width: 100%;
    display: flex;
    align-items: center;
    justify-content: center;
 }

Here's the quote on AssemblyInfo.cs from MSDN:

You can specify all the values or you can accept the default build number, revision number, or both by using an asterisk (). For example, [assembly:AssemblyVersion("2.3.25.1")] indicates 2 as the major version, 3 as the minor version, 25 as the build number, and 1 as the revision number. A version number such as [assembly:AssemblyVersion("1.2.")] specifies 1 as the major version, 2 as the minor version, and accepts the default build and revision numbers. A version number such as [assembly:AssemblyVersion("1.2.15.*")] specifies 1 as the major version, 2 as the minor version, 15 as the build number, and accepts the default revision number. The default build number increments daily. The default revision number is random

This effectively says, if you put a 1.1.* into assembly info, only build number will autoincrement, and it will happen not after every build, but daily. Revision number will change every build, but randomly, rather than in an incrementing fashion.

This is probably enough for most use cases. If that's not what you're looking for, you're stuck with having to write a script which will autoincrement version # on pre-build step

The most simple solution for me has been to:

1)Select the Range and copy it (ctrl+c)

2)Create a new text file (anywhere, it will be deleted soon), open the text file and then paste in the excel information (ctrl+v)

3)Now that the information in Excel is in the text file, perform a select all in the text file (ctrl+a), and then copy (ctrl+c)

4)Go to the beginning of the original range in step 1, and paste over that old information from the copy in step 3.

DONE! No more false blanks! (you can now delete the temp text file)

Quentin's answer clearly states that i tag should not be used to define icons.

But, Holly suggested that span has no meaning in itself and voted in favor of i instead of span tag.

Few suggested to use img as it's semantic and contains alt tag. But, we should not also use img because even empty src sends a request to server. Read here

I think, the correct way would be,

<span class="icon-fb" role="img" aria-label="facebook"></span>

This solves the issue of no alt tag in span and makes it accessible to vision-impaired users. It's semantic and not misusing ( hacking ) any tag.

Just add a . to it:

svn checkout file:///home/landonwinters/svn/waterproject/trunk .

That means: check out to current directory.

It's worth noting that if your error is due to .htaccess, for example a missing rewrite_module, you'll still see the 500 internal server error.

Piggybacking on what the other answers say, since you don't know how to do them at all, here's an example of how you might do it in JavaScript:

var charactersOnly = "This contains only characters";
var nonCharacters = "This has _@#*($()*@#$(*@%^_(#@!$ non-characters";

if (charactersOnly.search(/[^a-zA-Z]+/) === -1) {
  alert("Only characters");
}

if (nonCharacters.search(/[^a-zA-Z]+/)) {
  alert("There are non characters.");
}

The / starting and ending the regular expression signify that it's a regular expression. The search function takes both strings and regexes, so the / are necessary to specify a regex.

From the MDN Docs, the function returns -1 if there is no match.

Also note: that this works for only a-z, A-Z. If there are spaces, it will fail.

OK, let's go a bit more comprehensive and start with what's Map for those who don't know this feature in JavaScript... MDN says:

The Map object holds key-value pairs and remembers the original insertion order of the keys.
Any value (both objects and primitive values) may be used as either a key or a value.

As you mentioned, you can easily create an instance of Map using new keyword... In your case:

let myMap = new Map().set('a', 1).set('b', 2);

So let's see...

The way you mentioned is an OK way to do it, but yes, there are more concise ways to do that...

Map has many methods which you can use, like set() which you already used to assign the key values...

One of them is keys() which returns all the keys...

In your case, it will return:

MapIterator {"a", "b"}

and you easily convert them to an Array using ES6 ways, like spread operator...

const b = [...myMap.keys()];

I think all the above do not answer this question due to following reasons,

1. Since same functionality can be achieved by using other collections such as TreeSet, Collections, PriorityQueue..etc (but this is an alternative which will also impose their constraints i.e. Set will remove duplicate elements. Simply saying even if it does not impose any constraint, it does not answer the question why SortedList was not created by java community)
2. Since List elements do not implements compare/equals methods (This holds true for Set & Map also where in general items do not implement Comparable interface but when we need these items to be in sorted order & want to use TreeSet/TreeMap,items should implement Comparable interface)
3. Since List uses indexing & due to sorting it won't work (This can be easily handled introducing intermediate interface/abstract class)

but none has told the exact reason behind it & as I believe these kind of questions can be best answered by java community itself as it will have only one & specific answer but let me try my best to answer this as following,

As we know sorting is an expensive operation and there is a basic difference between List & Set/Map that List can have duplicates but Set/Map can not. This is the core reason why we have got a default implementation for Set/Map in form of TreeSet/TreeMap. Internally this is a Red Black Tree with every operation (insert/delete/search) having the complexity of O(log N) where due to duplicates List could not fit in this data storage structure.

Now the question arises we could also choose a default sorting method for List also like MergeSort which is used by Collections.sort(list) method with the complexity of O(N log N). Community did not do this deliberately since we do have multiple choices for sorting algorithms for non distinct elements like QuickSort, ShellSort, RadixSort...etc. In future there can be more. Also sometimes same sorting algorithm performs differently depending on the data to be sorted. Therefore they wanted to keep this option open and left this on us to choose. This was not the case with Set/Map since O(log N) is the best sorting complexity.

In jQuery, the $ sign is just an alias to jQuery(), then an alias to a function.

This page reports:

Basic syntax is: $(selector).action()

• A dollar sign to define jQuery
• A (selector) to "query (or find)" HTML elements
• A jQuery action() to be performed on the element(s)

            u8arr = new Uint8Array(n);_x000D_
            _x000D_
        while(n--){_x000D_
            u8arr[n] = bstr.charCodeAt(n);_x000D_
        }_x000D_
        _x000D_
        return new File([u8arr], filename, {type:mime});_x000D_
    }_x000D_
    _x000D_
    //Usage example:_x000D_
    var file = dataURLtoFile('data:text/plain;base64,aGVsbG8gd29ybGQ=','hello.txt');_x000D_
    console.log(file);

Way 2: works for any type of url, (http url, dataURL, blobURL, etc...)

 //return a promise that resolves with a File instance_x000D_
    function urltoFile(url, filename, mimeType){_x000D_
        return (fetch(url)_x000D_
            .then(function(res){return res.arrayBuffer();})_x000D_
            .then(function(buf){return new File([buf], filename,{type:mimeType});})_x000D_
        );_x000D_
    }_x000D_
    _x000D_
    //Usage example:_x000D_
    urltoFile('data:text/plain;base64,aGVsbG8gd29ybGQ=', 'hello.txt','text/plain')_x000D_
    .then(function(file){ console.log(file);});

If the method of this code is not static, you can get a work-around in 5.2 by using get_class($this).

class A {
    public function create1() {
        $class = get_class($this);
        return new $class();
    }
    public function create2() {
        return new static();
    }
}

class B extends A {

}

$b = new B();
var_dump(get_class($b->create1()), get_class($b->create2()));

The results:

string(1) "B"
string(1) "B"

In my case, I turned off X-Content-Type-Options on nginx then works fine. But make sure this declines your security level a little. Would be a temporally fix.

# Not work
add_header X-Content-Type-Options nosniff;
# OK (comment out)
#add_header X-Content-Type-Options nosniff;

It'll be the same for apache.

<IfModule mod_headers.c>
  #Header set X-Content-Type-Options nosniff
</IfModule>

Renders a view and sends the rendered HTML string to the client.

res.render('index');

Or

res.render('index', function(err, html) {
  if(err) {...}
  res.send(html);

I found this blog post very helpful. It saved my day. http://www.techsirius.com/2014/05/simple-geo-tracking-system.html

Basically you need to install the IP database table and then do mysql query for the IP for location.

<?php
include 'config.php';
mysql_connect(DB_HOST, DB_USER, DB_PASSWORD) OR die(mysql_error());
mysql_select_db(DB_NAME) OR die(mysql_error());
$ip =  $_SERVER['REMOTE_ADDR'];
$long = sprintf('%u', ip2long($ip));
$sql = "SELECT * FROM `geo_ips` WHERE '$long' BETWEEN `ip_start` AND `ip_end`";
$result = mysql_query($sql) OR die(mysql_error());
$ip_detail = mysql_fetch_assoc($result);
if($ip_detail){
    echo $ip_detail['country']."', '".$ip_detail['state']."', '".$ip_detail['city'];
}
else{
    //Something wrong with IP
}

Add to your settings.py:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'file': {
            'level': 'DEBUG',
            'class': 'logging.FileHandler',
            'filename': 'debug.log',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['file'],
            'level': 'DEBUG',
            'propagate': True,
        },
    },
}

And it will create a file called debug.log in the root of your. https://docs.djangoproject.com/en/1.10/topics/logging/

For those using CloudFormation template. You can set AWS_DEFAULT_REGION environment variable using UserData and AWS::Region. For example,

MyInstance1:
    Type: AWS::EC2::Instance                
    Properties:                           
        ImageId: ami-04b9e92b5572fa0d1 #ubuntu
        InstanceType: t2.micro
        UserData: 
            Fn::Base64: !Sub |
                    #!/bin/bash -x

                    echo "export AWS_DEFAULT_REGION=${AWS::Region}" >> /etc/profile

Effects are always executed after the render phase is completed even if you setState inside the one effect, another effect will read the updated state and take action on it only after the render phase.

Having said that its probably better to take both actions in the same effect unless there is a possibility that b can change due to reasons other than changing a in which case too you would want to execute the same logic

Using python3 pathlib library:

import re
from pathlib import Path
import shutil

shutil.copy2("/tmp/test.xml", "/tmp/test.xml.bak") # create backup
filepath = Path("/tmp/test.xml")
content = filepath.read_text()
filepath.write_text(re.sub(r"<string>ABC</string>(\s+)<string>(.*)</string>",r"<xyz>ABC</xyz>\1<xyz>\2</xyz>", content))

Similar method using different approach to backups:

from pathlib import Path

filepath = Path("/tmp/test.xml")
filepath.rename(filepath.with_suffix('.bak')) # different approach to backups
content = filepath.read_text()
filepath.write_text(re.sub(r"<string>ABC</string>(\s+)<string>(.*)</string>",r"<xyz>ABC</xyz>\1<xyz>\2</xyz>", content))

Safer.

$galleries = array(1,2,5);
array_walk($galleries , 'intval');
$ids = implode(',', $galleries);
$sql = "SELECT * FROM galleries WHERE id IN ($ids)";

Let's take a normal list (implemented by the ArrayList class) and make it synchronized. This is shown in the SynchronizedListExample class. We pass the Collections.synchronizedList method a new ArrayList of Strings. The method returns a synchronized List of Strings. //Here is SynchronizedArrayList class

package com.mnas.technology.automation.utility;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Iterator;
import java.util.List;
import org.apache.log4j.Logger;
/**
* 
* @author manoj.kumar
* @email [email protected]
* 
*/
public class SynchronizedArrayList {
    static Logger log = Logger.getLogger(SynchronizedArrayList.class.getName());
    public static void main(String[] args) {    
        List<String> synchronizedList = Collections.synchronizedList(new ArrayList<String>());
        synchronizedList.add("Aditya");
        synchronizedList.add("Siddharth");
        synchronizedList.add("Manoj");
        // when iterating over a synchronized list, we need to synchronize access to the synchronized list
        synchronized (synchronizedList) {
            Iterator<String> iterator = synchronizedList.iterator();
            while (iterator.hasNext()) {
                log.info("Synchronized Array List Items: " + iterator.next());
            }
        }    
    }
}

Notice that when iterating over the list, this access is still done using a synchronized block that locks on the synchronizedList object. In general, iterating over a synchronized collection should be done in a synchronized block

If you want to have control over where they are placed separate from source code order:

Demo: http://jsfiddle.net/NmL2W/

<div id="NW"></div>
<div id="NE"></div>
<div id="SE"></div>?
<div id="SW"></div>

html, body { height:100%; margin:0; padding:0 }
div { position:fixed; width:50%; height:50% }
#NW { top:0;   left:0;   background:orange  }
#NE { top:0;   left:50%; background:blue    }
#SW { top:50%; left:0;   background:green   }
#SE { top:50%; left:50%; background:red     }    ?

Note: if you want padding on your regions, you'll need to set the box-sizing to border-box:

div {
  /* ... */
  padding:1em;
  box-sizing:border-box;
  -moz-box-sizing:border-box;
  -webkit-box-sizing:border-box;
}

…otherwise your "50%" width and height become "50% + 2em", which will lead to visual overlaps.

See C# specification. There are three types of division operators

• Integer division
• Floating-point division
• Decimal division

In your case we have Integer division, with following rules applied:

The division rounds the result towards zero, and the absolute value of the result is the largest possible integer that is less than the absolute value of the quotient of the two operands. The result is zero or positive when the two operands have the same sign and zero or negative when the two operands have opposite signs.

I think the reason why C# use this type of division for integers (some languages return floating result) is hardware - integers division is faster and simpler.

Your code below is zooming the map to fit the specified bounds:

addMarker(27.703402,85.311668,'New Road');
center = bounds.getCenter();
map.fitBounds(bounds);

If you only have 1 marker and add it to the bounds, that results in the closest zoom possible:

function addMarker(lat, lng, info) {
  var pt = new google.maps.LatLng(lat, lng);
  bounds.extend(pt);
}

If you keep track of the number of markers you have "added" to the map (or extended the bounds with), you can only call fitBounds if that number is greater than one. I usually push the markers into an array (for later use) and test the length of that array.

If you will only ever have one marker, don't use fitBounds. Call setCenter, setZoom with the marker position and your desired zoom level.

function addMarker(lat, lng, info) {
  var pt = new google.maps.LatLng(lat, lng);
  map.setCenter(pt);
  map.setZoom(your desired zoom);
}

As far as I can tell after reading the docs for javadoc there is no such feature.

Don't use <code>foo</code> as recommended in other answers; you can use {@code foo}. This is especially good to know when you refer to a generic type such as {@code Iterator<String>} -- sure looks nicer than <code>Iterator&lt;String&gt;</code>, doesn't it!

Old question, but none of the answers satisfies me. One of my systems is running Ubuntu 12.04 LTS and for some reason there's no package python3-pip or python-pip for Python 3. So here is what I've done (all commands were executed as root):

• Install setuptools for Python3 in case you haven't.

  apt-get install python3-setuptools
  

  or

  aptitude install python3-setuptools
  

• With Python 2.4+ you can invoke easy_install with specific Python version by using python -m easy_install. So pip for Python 3 could be installed by:

  python3 -m easy_install pip
  

• That's it, you got pip for Python 3. Now just invoke pip with the specific version of Python to install package for Python 3. For example, with Python 3.2 installed on my system, I used:

  pip-3.2 install [package]
  

I usually create a dictionary containing a DataFrame for every sheet:

xl_file = pd.ExcelFile(file_name)

dfs = {sheet_name: xl_file.parse(sheet_name) 
          for sheet_name in xl_file.sheet_names}

Update: In pandas version 0.21.0+ you will get this behavior more cleanly by passing sheet_name=None to read_excel:

dfs = pd.read_excel(file_name, sheet_name=None)

In 0.20 and prior, this was sheetname rather than sheet_name (this is now deprecated in favor of the above):

dfs = pd.read_excel(file_name, sheetname=None)

Calendar.getInstance().get(Calendar.DAY_OF_WEEK)

or

new GregorianCalendar().get(Calendar.DAY_OF_WEEK);

Just the same as in Java, nothing particular to Android.

1. In vim, you save a file with :wEnter while in the normal mode (you get to the normal mode by pressing Esc).
2. You close your file with :q while in the normal mode.

You can combine both these actions and do Esc:wqEnter to save the commit and quit vim.

As an alternate to the above, you can also press ZZ while in the normal mode, which will save the file and exit vim. This is also easier for some people as it's the same key pressed twice.

Use

__DIR__

to get the current path of the script and this should fix your problem.

So:

require_once(__DIR__.'/../class/user.php');

This will prevent cases where you can run a PHP script from a different folder and therefore the relatives paths will not work.

Edit: slash problem fixed

Because the number can be up to 15 digits, you'll need to cast to an 64 bit (8-byte) integer. Try this:

SELECT * FROM table
WHERE myint = mytext::int8

The :: cast operator is historical but convenient. Postgres also conforms to the SQL standard syntax

myint = cast ( mytext as int8)

If you have literal text you want to compare with an int, cast the int to text:

SELECT * FROM table
WHERE myint::varchar(255) = mytext

random.shuffle should work. Here's an example, where the objects are lists:

from random import shuffle
x = [[i] for i in range(10)]
shuffle(x)

# print(x)  gives  [[9], [2], [7], [0], [4], [5], [3], [1], [8], [6]]
# of course your results will vary

Note that shuffle works in place, and returns None.

read last 3 characters from string [Initially asked question]

You can use string.Substring and give it the starting index and it will get the substring starting from given index till end.

myString.Substring(myString.Length-3)

Retrieves a substring from this instance. The substring starts at a specified character position. MSDN

Edit, for updated post

Remove last 3 characters from string [Updated question]

To remove the last three characters from the string you can use string.Substring(Int32, Int32) and give it the starting index 0 and end index three less than the string length. It will get the substring before last three characters.

myString = myString.Substring(0, myString.Length-3);

String.Substring Method (Int32, Int32)

Retrieves a substring from this instance. The substring starts at a specified character position and has a specified length.

You can also using String.Remove(Int32) method to remove the last three characters by passing start index as length - 3, it will remove from this point to end of string.

myString = myString.Remove(myString.Length-3)

String.Remove Method (Int32)

Returns a new string in which all the characters in the current instance, beginning at a specified position and continuing through the last position, have been deleted

It is .shape:

ndarray.shape
Tuple of array dimensions.

Thus:

>>> a.shape
(2, 2)

In a latest Jenkins (1.639 and above) you can:

1. just specify name of tag in a field 'Branches to build'.
2. in a parametrized build you can use parameter as variable in a same field 'Branches to build' i.e. ${Branch_to_build}.
3. you can install Git Parameter Plugin which will provide to you functionality by listing of all available branches and tags.

I solved this question with solution below

  import org.joda.time.LocalDate;
  Date myDate = new Date();
  LocalDate localDate = LocalDate.fromDateFields(myDate);
  System.out.println("My date using Date" Nov 18 11:23:33 BRST 2016);
  System.out.println("My date using joda.time LocalTime" 2016-11-18);

In this case localDate print your date in this format "yyyy-MM-dd"

If "budget" has any NaN values but you don't want it to sum to NaN then try:

def fun (b, a):
    if math.isnan(b):
        return a
    else:
        return b + a

f = np.vectorize(fun, otypes=[float])

df['variance'] = f(df['budget'], df_Lp['actual'])

It'd be better to use List<T>.RemoveAll to accomplish this.

authorsList.RemoveAll((x) => x.firstname == "Bob");

First of all, you lack parentheses to call GetType. What you see is the MethodInfo describing the GetType method on [DayOfWeek]. To actually call GetType, you should do:

$a.GetType();
$b.GetType();

You should see that $a is a [DayOfWeek], and $b is a custom object generated by the Select-Object cmdlet to capture only the DayOfWeek property of a data object. Hence, it's an object with a DayOfWeek property only:

C:\> $b.DayOfWeek -eq $a
True
