Spring Data is a convenience library on top of JPA that abstracts away many things and brings Spring magic (like it or not) to the persistence store access. It is primarily used for working with relational databases. In short, it allows you to declare interfaces that have methods like findByNameOrderByAge(String name); that will be parsed in runtime and converted into appropriate JPA queries.

Its placement atop of JPA makes its use tempting for:

1. Rookie developers who don't know SQL or know it badly. This is a recipe for disaster but they can get away with it if the project is trivial.

2. Experienced engineers who know what they do and want to spindle up things fast. This might be a viable strategy (but read further).

From my experience with Spring Data, its magic is too much (this is applicable to Spring in general). I started to use it heavily in one project and eventually hit several corner cases where I couldn't get the library out of my way and ended up with ugly workarounds. Later I read other users' complaints and realized that these issues are typical for Spring Data. For example, check this issue that led to hours of investigation/swearing:

 public TourAccommodationRate createTourAccommodationRate(
        @RequestBody TourAccommodationRate tourAccommodationRate
    ) {
        if (tourAccommodationRate.getId() != null) {
            throw new BadRequestException("id MUST NOT be specified in a body during entry creation");
        }

        // This is an ugly hack required for the Room slim model to work. The problem stems from the fact that
        // when we send a child entity having the many-to-many (M:N) relation to the containing entity, its
        // information is not fetched. As a result, we get NPEs when trying to access all but its Id in the
        // code creating the corresponding slim model. By detaching the entity from the persistence context we
        // force the ORM to re-fetch it from the database instead of taking it from the cache

        tourAccommodationRateRepository.save(tourAccommodationRate);
        entityManager.detach(tourAccommodationRate);
        return tourAccommodationRateRepository.findOne(tourAccommodationRate.getId());
    }

I ended up going lower level and started using JDBI - a nice library with just enough "magic" to save you from the boilerplate. With it, you have complete control over SQL queries and almost never have to fight the library.

To remove just a few specific files from being tracked:

git update-index --assume-unchanged path/to/file

If ever you want to start tracking it again:

git update-index --no-assume-unchanged path/to/file                      

A solution without your indentation:

for path, dirs, files in os.walk(given_path):
  print path
  for f in files:
    print f

os.walk already does the top-down, depth-first walk you are looking for.

Ignoring the dirs list prevents the overlapping you mention.

Try:

NSComparisonResult order = [[UIDevice currentDevice].systemVersion compare: @"3.1.3" options: NSNumericSearch];
if (order == NSOrderedSame || order == NSOrderedDescending) {
    // OS version >= 3.1.3
} else {
    // OS version < 3.1.3
}

>>> import math
>>> import numpy as np
>>> import scipy
>>> math.pi == np.pi == scipy.pi
True

So it doesn't matter, they are all the same value.

The only reason all three modules provide a pi value is so if you are using just one of the three modules, you can conveniently have access to pi without having to import another module. They're not providing different values for pi.

If running Windows 10:

1. Open the start menu
2. Type path
3. Click Edit the system environment variables (usually, it's the top search result) and continue on step 6 below.

If on older Windows:

1. Show Desktop.

2. Right Click My Computer shortcut in the desktop.

3. Click Properties.

4. You should see a section of control Panel - Control Panel\System and Security\System.

5. Click Advanced System Settings on the Left menu.

6. Click Enviornment Variables towards the bottom of the System Properties window.

7. Select PATH in the user variables list.

8. Append your PHP Path (C:\myfolder\php) to your PATH variable, separated from the already existing string by a semi colon.

9. Click OK

10. Open your "cmd"

11. Type PATH, press enter

12. Make sure that you see your PHP folder among the list.

That should work.

Note: Make sure that your PHP folder has the php.exe. It should have the file type CLI. If you do not have the php.exe, go ahead and check the installation guidelines at - http://www.php.net/manual/en/install.windows.manual.php - and download the installation file from there.

What you could do is have the selected attribute on the <select> tag be an attribute of this.state that you set in the constructor. That way, the initial value you set (the default) and when the dropdown changes you need to change your state.

constructor(){
  this.state = {
    selectedId: selectedOptionId
  }
}

dropdownChanged(e){
  this.setState({selectedId: e.target.value});
}

render(){
  return(
    <select value={this.selectedId} onChange={this.dropdownChanged.bind(this)}>
      {option_id.map(id =>
        <option key={id} value={id}>{options[id].name}</option>
      )}
    </select>
  );
}

If your intention was to find a way to represent null in an enumeration of singleton objects, then it's a bad idea to (de)reference null (it C++11, nullptr).

Why not declare static singleton object that represents NULL within the class as follows and add a cast-to-pointer operator that returns nullptr ?

Edit: Corrected several mistypes and added if-statement in main() to test for the cast-to-pointer operator actually working (which I forgot to.. my bad) - March 10 2015 -

// Error.h
class Error {
public:
  static Error& NOT_FOUND;
  static Error& UNKNOWN;
  static Error& NONE; // singleton object that represents null

public:
  static vector<shared_ptr<Error>> _instances;
  static Error& NewInstance(const string& name, bool isNull = false);

private:
  bool _isNull;
  Error(const string& name, bool isNull = false) : _name(name), _isNull(isNull) {};
  Error() {};
  Error(const Error& src) {};
  Error& operator=(const Error& src) {};

public:
  operator Error*() { return _isNull ? nullptr : this; }
};

// Error.cpp
vector<shared_ptr<Error>> Error::_instances;
Error& Error::NewInstance(const string& name, bool isNull = false)
{
  shared_ptr<Error> pNewInst(new Error(name, isNull)).
  Error::_instances.push_back(pNewInst);
  return *pNewInst.get();
}

Error& Error::NOT_FOUND = Error::NewInstance("NOT_FOUND");
//Error& Error::NOT_FOUND = Error::NewInstance("UNKNOWN"); Edit: fixed
//Error& Error::NOT_FOUND = Error::NewInstance("NONE", true); Edit: fixed
Error& Error::UNKNOWN = Error::NewInstance("UNKNOWN");
Error& Error::NONE = Error::NewInstance("NONE");

// Main.cpp
#include "Error.h"

Error& getError() {
  return Error::UNKNOWN;
}

// Edit: To see the overload of "Error*()" in Error.h actually working
Error& getErrorNone() {
  return Error::NONE;
}

int main(void) {
  if(getError() != Error::NONE) {
    return EXIT_FAILURE;
  }

  // Edit: To see the overload of "Error*()" in Error.h actually working
  if(getErrorNone() != nullptr) {
    return EXIT_FAILURE;
  }
}

Using lodash:

function csvToJson(csv) {
  const content = csv.split('\n');
  const header = content[0].split(',');
  return _.tail(content).map((row) => {
    return _.zipObject(header, row.split(','));
  });
}

If you're using Kotlin, I achieved this by using a Kotlin extension:

fun TextView.htmlText(text: String){
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        setText(Html.fromHtml(text, Html.FROM_HTML_MODE_LEGACY))
    } else {
        setText(Html.fromHtml(text))
    }
}

Then call it like:

textView.htmlText(yourHtmlText)

Updated Answer: Up Navigation Design

You have to declare which activity is the appropriate parent for each activity. Doing so allows the system to facilitate navigation patterns such as Up because the system can determine the logical parent activity from the manifest file.

So for that you have to declare your parent Activity in tag Activity with attribute

android:parentActivityName

Like,

<!-- The main/home activity (it has no parent activity) -->
    <activity
        android:name="com.example.app_name.A" ...>
        ...
    </activity>
    <!-- A child of the main activity -->
    <activity
        android:name=".B"
        android:label="B"
        android:parentActivityName="com.example.app_name.A" >
        <!-- Parent activity meta-data to support 4.0 and lower -->
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.example.app_name.A" />
    </activity>

With the parent activity declared this way, you can navigate Up to the appropriate parent like below,

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    // Respond to the action bar's Up/Home button
    case android.R.id.home:
        NavUtils.navigateUpFromSameTask(this);
        return true;
    }
    return super.onOptionsItemSelected(item);
}

So When you call NavUtils.navigateUpFromSameTask(this); this method, it finishes the current activity and starts (or resumes) the appropriate parent activity. If the target parent activity is in the task's back stack, it is brought forward as defined by FLAG_ACTIVITY_CLEAR_TOP.

And to display Up button you have to declare setDisplayHomeAsUpEnabled():

@Override
public void onCreate(Bundle savedInstanceState) {
    ...
    getActionBar().setDisplayHomeAsUpEnabled(true);
}

Old Answer: (Without Up Navigation, default Back Navigation)

It happen only if you are starting Activity A again from Activity B.

Using startActivity().

Instead of this from Activity A start Activity B using startActivityForResult() and override onActivtyResult() in Activity A.

Now in Activity B just call finish() on button Up. So now you directed to Activity A's onActivityResult() without creating of Activity A again..

why do you ever want to use out?

To let others know that the variable will be initialized when it returns from the called method!

As mentioned above: "for an out parameter, the calling method is required to assign a value before the method returns."

example:

Car car;
SetUpCar(out car);
car.drive();  // You know car is initialized.

Presenting the Cadillac of Diffs as an SP. See within for the basic template that was based on answer by @erikkallen. It supports

• Duplicate row sensing (most other answers here do not)
• Sort results by argument
• Limit to specific columns
• Ignore columns (e.g. ModifiedUtc)
• Cross database tables names
• Temp tables (use as workaround to diff views)

Usage:

exec Common.usp_DiffTableRows '#t1', '#t2';

exec Common.usp_DiffTableRows 
    @pTable0          = 'ydb.ysh.table1',
    @pTable1          = 'xdb.xsh.table2',
    @pOrderByCsvOpt   = null,  -- Order the results
    @pOnlyCsvOpt      = null,  -- Only compare these columns
    @pIgnoreCsvOpt    = null;  -- Ignore these columns (ignored if @pOnlyCsvOpt is specified)

Code:

alter proc [Common].[usp_DiffTableRows]    
    @pTable0          varchar(300),
    @pTable1          varchar(300),
    @pOrderByCsvOpt   nvarchar(1000) = null,  -- Order the Results
    @pOnlyCsvOpt      nvarchar(4000) = null,  -- Only compare these columns
    @pIgnoreCsvOpt    nvarchar(4000) = null,  -- Ignore these columns (ignored if @pOnlyCsvOpt is specified)

The Best way:

1. Disconnect the Iphone.
2. Clean xcode by command+ shift + k or by going to Product -> Clean

Connect again

Run again

According to Apple-doc

• Weak references are always of an optional type, and automatically become nil when the instance they reference is deallocated.

• If the captured reference will never become nil, it should always be captured as an unowned reference, rather than a weak reference

Example -

    // if my response can nil use  [weak self]
      resource.request().onComplete { [weak self] response in
      guard let strongSelf = self else {
        return
      }
      let model = strongSelf.updateModel(response)
      strongSelf.updateUI(model)
     }

    // Only use [unowned self] unowned if guarantees that response never nil  
      resource.request().onComplete { [unowned self] response in
      let model = self.updateModel(response)
      self.updateUI(model)
     }

The FileNameExtensionFilter class is intended for Swing to be used in a JFileChooser.

Try using a FilenameFilter instead. For example:

File dir = new File("/users/blah/dirname");
File[] files = dir.listFiles(new FilenameFilter() {
    public boolean accept(File dir, String name) {
        return name.toLowerCase().endsWith(".txt");
    }
});

int x = -1;
Calendar cal = ...;
cal.add(Calendar.DATE, x);

See java.util.Calendar#add(int,int)

• $_ last argument of last command
• $# number of arguments passed to current script
• $* / $@ list of arguments passed to script as string / delimited list

off the top of my head. Google for bash special variables.

Few steps that helped me (some of them are mentioned above):

Open project structure by:

command + ; (mac users) OR right click on the project -> Open Module Settings

1. Facets -> + -> Python -> <your-project> -> OK
2. Modules -> Python -> <select python interpreter>
3. Project -> Project SDK -> <select relevant SDK>
4. SDKs -> <make sure it's the right one>

Click OK.

Open Run/Debug Configurations by: Run -> Edit Configurations

5. Python Interpreter -> <make sure it's the right one>

Click OK.

function bootstrap_alert() {
        create = function (message, color) {
            $('#alert_placeholder')
                .html('<div class="alert alert-' + color
                    + '" role="alert"><a class="close" data-dismiss="alert">×</a><span>' + message
                    + '</span></div>');
        };
        warning = function (message) {
            create(message, "warning");
        };
        info = function (message) {
            create(message, "info");
        };
        light = function (message) {
            create(message, "light");
        };
        transparent = function (message) {
            create(message, "transparent");
        };
        return {

When dealing with a hash {}, use both the key and value to the block inside the ||.

details.map {|key,item|"" == item}

=>[false, false, true, false, false]

Both are correct. Oracle allows the use of both.

since I have no enough reputation to comment after the highest post, so I add here.

hope this help!

There are two ways:

1. If you are patient (requires Ubuntu corral pc and Android SDK and some heavy terminal work to get it all set up). See Using the 3.0 SDK without paying for the priviledge.

2. If you are immoral (requires Mac OS X Leopard and virtualization, both only obtainable through great expense or pirating) - remove space from the following link. htt p://iphonewo rld. codinghut.com /2009/07/using-the-3-0-sdk-without-paying-for-the-priviledge/

I use the Ubuntu method myself.

You should enable the Server authentication mode to mixed mode as following: In SQL Studio, select YourServer -> Property -> Security -> Select SqlServer and Window Authentication mode.

Just note the difference between the range operators:

3..10  # includes 10
3...10 # doesn't include 10

Personally I used this batch file, but it does require CygWin installed (64-bit as shown). Just associate the file type .SH with this batchfile (ExecSH.BAT in my case) and you can double-click on the .SH and it runs.

@echo off
setlocal

if not exist "%~dpn1.sh" echo Script "%~dpn1.sh" not found & goto :eof

set _CYGBIN=C:\cygwin64\bin
if not exist "%_CYGBIN%" echo Couldn't find Cygwin at "%_CYGBIN%" & goto :eof

:: Resolve ___.sh to /cygdrive based *nix path and store in %_CYGSCRIPT%
for /f "delims=" %%A in ('%_CYGBIN%\cygpath.exe "%~dpn1.sh"') do set _CYGSCRIPT=%%A
for /f "delims=" %%A in ('%_CYGBIN%\cygpath.exe "%CD%"') do set _CYGPATH=%%A

:: Throw away temporary env vars and invoke script, passing any args that were passed to us
endlocal & %_CYGBIN%\mintty.exe -e /bin/bash -l -c 'cd %_CYGPATH%;  %_CYGSCRIPT% %*'

Based on this original work.

How about something like this?

val newDF = df.filter($"B" === "").take(1) match {
  case Array() => df
  case _ => df.withColumn("D", $"B" === "")
}

Using take(1) should have a minimal hit

This will submit the right form response (i.e. Select value most of the time, and Input value when the Select box is set to "others"). Uses jQuery:

  $("select[name="color"]").change(function(){
    new_value = $(this).val();
    if (new_value == "others") {
      $('input[name="color"]').show();      
    } else {
      $('input[name="color"]').val(new_value);
      $('input[name="color"]').hide();
    }
  });

Asp.net is pretty good at automatically converting .net objects to json. Your List object if returned in your webmethod should return a json/javascript array. What I mean by this is that you shouldn't change the return type to string (because that's what you think the client is expecting) when returning data from a method. If you return a .net array from a webmethod a javaScript array will be returned to the client. It doesn't actually work too well for more complicated objects, but for simple array data its fine.

Of course, it's then up to you to do what you need to do on the client side.

I would be thinking something like this:

[WebMethod]
public static List GetProducts()
{
   var products  = context.GetProducts().ToList();   
   return products;
}

There shouldn't really be any need to initialise any custom converters unless your data is more complicated than simple row/col data

$(".radioValue").css({"background-color":"-webkit-linear-gradient(#e9e9e9,rgba(255, 255, 255, 0.43137254901960786),#e9e9e9)","color":"#454545", "padding": "8px"});

If you need a progmatic solution this should work in jQuery:

$(".abc.xyz").css("width", 200);

Found the code that I referred to in my comment above. To test it, do this:

1. In Sheet1 change the cell height and width of say A1 as shown in the snapshot below.
2. Format the cell by right clicking on it to show time format
3. Add two buttons (form controls) on the worksheet and name them as shown in the snapshot
4. Paste this code in a module
5. Right click on the Start Timer button on the sheet and click on Assign Macros. Select StartTimer macro.
6. Right click on the End Timer button on the sheet and click on Assign Macros. Select EndTimer macro.

Now click on Start Timer button and you will see the time getting updated in cell A1. To stop time updates, Click on End Timer button.

Code (TRIED AND TESTED)

Public Declare Function SetTimer Lib "user32" ( _
ByVal HWnd As Long, ByVal nIDEvent As Long, _
ByVal uElapse As Long, ByVal lpTimerFunc As Long) As Long

Public Declare Function KillTimer Lib "user32" ( _
ByVal HWnd As Long, ByVal nIDEvent As Long) As Long

Public TimerID As Long, TimerSeconds As Single, tim As Boolean
Dim Counter As Long

'~~> Start Timer
Sub StartTimer()
    '~~ Set the timer for 1 second
    TimerSeconds = 1
    TimerID = SetTimer(0&, 0&, TimerSeconds * 1000&, AddressOf TimerProc)
End Sub

'~~> End Timer
Sub EndTimer()
    On Error Resume Next
    KillTimer 0&, TimerID
End Sub

Sub TimerProc(ByVal HWnd As Long, ByVal uMsg As Long, _
ByVal nIDEvent As Long, ByVal dwTimer As Long)
    '~~> Update value in Sheet 1
    Sheet1.Range("A1").Value = Time
End Sub

SNAPSHOT

Generally RuntimeExceptions are exceptions that can be prevented programmatically. E.g NullPointerException, ArrayIndexOutOfBoundException. If you check for null before calling any method, NullPointerException would never occur. Similarly ArrayIndexOutOfBoundException would never occur if you check the index first. RuntimeException are not checked by the compiler, so it is clean code.

EDIT : These days people favor RuntimeException because the clean code it produces. It is totally a personal choice.

First you have to sort the dataframe by the count column max to min if it's not sorted that way already. In your post, it is in the right order already but I will sort it anyways:

dataframe.sort_index(by='count', ascending=[False])
    col     count
0   apple   5
1   sausage 2
2   banana  2
3   cheese  1 

Then you can output the col column to a list:

dataframe['col'].tolist()
['apple', 'sausage', 'banana', 'cheese']

How about using lambda?

 if reduce( (lambda x, y: x and foo.has_key(y) ), [ True, "foo", "bar"] ): # do stuff

You can do it in a single command line:

cut -d: -f1,4 /etc/passwd | grep $(getent group <groupname> | cut -d: -f3) | cut -d: -f1

Above command lists all the users having groupname as their primary group

If you also want to list the users having groupname as their secondary group, use following command

getent group <groupname> | cut -d: -f4 |  tr ',' '\n'

The other solutions cite a lot of external code bases. If you would prefer to do it yourself, here is some code for a cross-platform solution that uses the respective file locking tools on Linux / DOS systems.

try:
    # Posix based file locking (Linux, Ubuntu, MacOS, etc.)
    #   Only allows locking on writable files, might cause
    #   strange results for reading.
    import fcntl, os
    def lock_file(f):
        if f.writable(): fcntl.lockf(f, fcntl.LOCK_EX)
    def unlock_file(f):
        if f.writable(): fcntl.lockf(f, fcntl.LOCK_UN)
except ModuleNotFoundError:
    # Windows file locking
    import msvcrt, os
    def file_size(f):
        return os.path.getsize( os.path.realpath(f.name) )
    def lock_file(f):
        msvcrt.locking(f.fileno(), msvcrt.LK_RLCK, file_size(f))
    def unlock_file(f):
        msvcrt.locking(f.fileno(), msvcrt.LK_UNLCK, file_size(f))


# Class for ensuring that all file operations are atomic, treat
# initialization like a standard call to 'open' that happens to be atomic.
# This file opener *must* be used in a "with" block.
class AtomicOpen:
    # Open the file with arguments provided by user. Then acquire
    # a lock on that file object (WARNING: Advisory locking).
    def __init__(self, path, *args, **kwargs):
        # Open the file and acquire a lock on the file before operating
        self.file = open(path,*args, **kwargs)
        # Lock the opened file
        lock_file(self.file)

    # Return the opened file object (knowing a lock has been obtained).
    def __enter__(self, *args, **kwargs): return self.file

    # Unlock the file and close the file object.
    def __exit__(self, exc_type=None, exc_value=None, traceback=None):        
        # Flush to make sure all buffered contents are written to file.
        self.file.flush()
        os.fsync(self.file.fileno())
        # Release the lock on the file.
        unlock_file(self.file)
        self.file.close()
        # Handle exceptions that may have come up during execution, by
        # default any exceptions are raised to the user.
        if (exc_type != None): return False
        else:                  return True        

Now, AtomicOpen can be used in a with block where one would normally use an open statement.

WARNINGS:

• If running on Windows and Python crashes before exit is called, I'm not sure what the lock behavior would be.
• The locking provided here is advisory, not absolute. All potentially competing processes must use the "AtomicOpen" class.
• As of (Nov 9th, 2020) this code only locks writable files on Posix systems. At some point after the posting and before this date, it became illegal to use the fcntl.lock on read-only files.

If you want to match the two words in either order, use:

gci C:\Logs| select-string -pattern '(VendorEnquiry.*Failed)|(Failed.*VendorEnquiry)'

If Failed always comes after VendorEnquiry on the line, just use:

gci C:\Logs| select-string -pattern '(VendorEnquiry.*Failed)'

I don't see any answer with reference to CSS flex property, but it can be very useful too.

Use:

$filelist = @("11", "1", "2")
$filelist | sort @{expression={[int]$_}} | % {$newName = [string]([int]$_ + 1)}
New-Item $newName -ItemType Directory

public class Outer {
   public static class Inner {}
}

... it can be declared static - as long as it is a member class.

From the JLS:

Member classes may be static, in which case they have no access to the instance variables of the surrounding class; or they may be inner classes (§8.1.3).

and here:

The static keyword may modify the declaration of a member type C within the body of a non-inner class T. Its effect is to declare that C is not an inner class. Just as a static method of T has no current instance of T in its body, C also has no current instance of T, nor does it have any lexically enclosing instances.

A static keyword wouldn't make any sense for a top level class, just because a top level class has no enclosing type.

The new official AWS CLI natively supports most of the functionality of s3cmd. I'd previously been using s3cmd or the ruby AWS SDK to do things like this, but the official CLI works great for this.

[Late answer in response to a bounty asking for newer responses]

Looking over earlier answers,

• Fetching and deleting all items, as suggested by @Grouchal and others, is still an effective and useful solution. If you have very large data stores then it might be slow, but it still works very well.
• Simply removing the data store is, as you and @groundhog note, no longer effective. It's obsolete even if you don't use external binary storage because iOS 7 uses WAL mode for SQLite journalling. With WAL mode there may be (potentially large) journal files sitting around for any Core Data persistent store.

But there's a different, similar approach to removing the persistent store that does work. The key is to put your persistent store file in its own sub-directory that doesn't contain anything else. Don't just stick it in the documents directory (or wherever), create a new sub-directory just for the persistent store. The contents of that directory will end up being the persistent store file, the journal files, and the external binary files. If you want to nuke the entire data store, delete that directory and they'll all disappear.

You'd do something like this when setting up your persistent store:

NSURL *storeDirectoryURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"persistent-store"];
if ([[NSFileManager defaultManager] createDirectoryAtURL:storeDirectoryURL
        withIntermediateDirectories:NO
        attributes:nil
        error:nil]) {
    NSURL *storeURL = [storeDirectoryURL URLByAppendingPathComponent:@"MyApp.sqlite"];
    // continue with storeURL as usual...
}

Then when you wanted to remove the store,

[[NSFileManager defaultManager] removeItemAtURL:storeDirectoryURL error:nil];

That recursively removes both the custom sub-directory and all of the Core Data files in it.

This only works if you don't already have your persistent store in the same folder as other, important data. Like the documents directory, which probably has other useful stuff in it. If that's your situation, you could get the same effect by looking for files that you do want to keep and removing everything else. Something like:

NSString *docsDirectoryPath = [[self applicationDocumentsDirectory] path];
NSArray *docsDirectoryContents = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:docsDirectoryPath error:nil];
for (NSString *docsDirectoryItem in docsDirectoryContents) {
    // Look at docsDirectoryItem. If it's something you want to keep, do nothing.
    // If it's something you don't recognize, remove it.
}

This approach may be error prone. You've got to be absolutely sure that you know every file you want to keep, because otherwise you might remove important data. On the other hand, you can remove the external binary files without actually knowing the file/directory name used to store them.

function instanceOf(object) {
  var type = typeof object

  if (type === 'undefined') {
    return 'undefined'
  }

  if (object) {
    type = object.constructor.name
  } else if (type === 'object') {
    type = Object.prototype.toString.call(object).slice(8, -1)
  }

  return type.toLowerCase()
}

instanceOf(false)                  // "boolean"
instanceOf(new Promise(() => {}))  // "promise"
instanceOf(null)                   // "null"
instanceOf(undefined)              // "undefined"
instanceOf(1)                      // "number"

Just add the display:block to the thead > tr and tbody. check the below example

There is an event Page.Unload. At that moment page is already rendered in HTML and HTML can't be modified. Still, all page objects are available.

I got stuck on this issue for a long time following all the different remedies without avail.

I noticed that when adding a forward slash [/] to the end of the URL containing the dots [.], it did not throw a 404 error and it actually worked.

I finally solved the issue using a URL rewriter like IIS URL Rewrite to watch for a particular pattern and append the training slash.

My URL looks like this: /Contact/~firstname.lastname so my pattern is simply: /Contact/~(.*[^/])$

I got this idea from Scott Forsyth, see link below: http://weblogs.asp.net/owscott/handing-mvc-paths-with-dots-in-the-path

Another simple example from here..

SELECT * FROM dbo.Employee
ORDER BY 
 CASE WHEN Gender='Male' THEN EmployeeName END Desc,
 CASE WHEN Gender='Female' THEN Country END ASC

Here's an example of applying dropshadow to some svg using the 'filter' property. If you want to control the opacity of the dropshadow have a look at this example. The slope attribute controls how much opacity to give to the dropshadow.

Relevant bits from the example:

<filter id="dropshadow" height="130%">
  <feGaussianBlur in="SourceAlpha" stdDeviation="3"/> <!-- stdDeviation is how much to blur -->
  <feOffset dx="2" dy="2" result="offsetblur"/> <!-- how much to offset -->
  <feComponentTransfer>
    <feFuncA type="linear" slope="0.5"/> <!-- slope is the opacity of the shadow -->
  </feComponentTransfer>
  <feMerge> 
    <feMergeNode/> <!-- this contains the offset blurred image -->
    <feMergeNode in="SourceGraphic"/> <!-- this contains the element that the filter is applied to -->
  </feMerge>
</filter>
<circle r="10" style="filter:url(#dropshadow)"/>

Box-shadow is defined to work on CSS boxes (read: rectangles), while svg is a bit more expressive than just rectangles. Read the SVG Primer to learn a bit more about what you can do with SVG filters.

For those who created rating bar programmatically and want set small rating bar instead of default big rating bar

    private LinearLayout generateRatingView(float value){
        LinearLayout linearLayoutRating=new LinearLayout(getContext());
        linearLayoutRating.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
        linearLayoutRating.setGravity(Gravity.CENTER);
        RatingBar ratingBar = new RatingBar(getContext(),null, android.R.attr.ratingBarStyleSmall);
        ratingBar.setEnabled(false);
        ratingBar.setStepSize(Float.parseFloat("0.5"));//for enabling half star
        ratingBar.setNumStars(5);
        ratingBar.setRating(value);
        linearLayoutRating.addView(ratingBar);
        return linearLayoutRating;
    }

I think the annotation you are looking for is:

public class CompanyName implements Serializable {
//...
@JoinColumn(name = "COMPANY_ID", referencedColumnName = "COMPANY_ID", insertable = false, updatable = false)
private Company company;

And you should be able to use similar mappings in a hbm.xml as shown here (in 23.4.2):

http://docs.jboss.org/hibernate/core/3.3/reference/en/html/example-mappings.html

I've tested this very thoroughly on a fairly complex, mildly nested multi-hash with all kinds of data in it (string, NULL, integers), and serialize/unserialize ended up much faster than json_encode/json_decode.

The only advantage json have in my tests was it's smaller 'packed' size.

These are done under PHP 5.3.3, let me know if you want more details.

Here are tests results then the code to produce them. I can't provide the test data since it'd reveal information that I can't let go out in the wild.

I had this problem yesterday. @Quentin's answer is ok:

No, you cannot reference one rule-set from another.

but I made a javascript function to simulate inheritance in css (like .Net):

    var inherit_array;_x000D_
    var inherit;_x000D_
    inherit_array = [];_x000D_
    Array.from(document.styleSheets).forEach(function (styleSheet_i, index) {_x000D_
        Array.from(styleSheet_i.cssRules).forEach(function (cssRule_i, index) {_x000D_
            if (cssRule_i.style != null) {_x000D_
                inherit = cssRule_i.style.getPropertyValue("--inherits").trim();_x000D_
            } else {_x000D_
                inherit = "";_x000D_
            }_x000D_
            if (inherit != "") {_x000D_
                inherit_array.push({ selector: cssRule_i.selectorText, inherit: inherit });_x000D_
            }_x000D_
        });_x000D_
    });_x000D_
    Array.from(document.styleSheets).forEach(function (styleSheet_i, index) {_x000D_
        Array.from(styleSheet_i.cssRules).forEach(function (cssRule_i, index) {_x000D_
            if (cssRule_i.selectorText != null) {_x000D_
                inherit_array.forEach(function (inherit_i, index) {_x000D_
                    if (cssRule_i.selectorText.split(", ").includesMember(inherit_i.inherit.split(", ")) == true) {_x000D_
                        cssRule_i.selectorText = cssRule_i.selectorText + ", " + inherit_i.selector;_x000D_
                    }_x000D_
                });_x000D_
            }_x000D_
        });_x000D_
    });

Array.prototype.includesMember = function (arr2) {_x000D_
    var arr1;_x000D_
    var includes;_x000D_
    arr1 = this;_x000D_
    includes = false;_x000D_
    arr1.forEach(function (arr1_i, index) {_x000D_
        if (arr2.includes(arr1_i) == true) {_x000D_
            includes = true;_x000D_
        }_x000D_
    });_x000D_
    return includes;_x000D_
}

and equivalent css:

.test {_x000D_
    background-color: yellow;_x000D_
}_x000D_
_x000D_
.productBox, .imageBox {_x000D_
    --inherits: .test;_x000D_
    display: inline-block;_x000D_
}

and equivalent HTML :

<div class="imageBox"></div>

I tested it and worked for me, even if rules are in different css files.

Update: I found a bug in hierarchichal inheritance in this solution, and am solving the bug very soon .

ActiveXObject is available only on IE browser. So every other useragent will throw an error

On modern browser you could use instead File API or File writer API (currently implemented only on Chrome)

See,

There are two ways to convert an RDD to DF in Spark.

toDF() and createDataFrame(rdd, schema)

I will show you how you can do that dynamically.

toDF()

The toDF() command gives you the way to convert an RDD[Row] to a Dataframe. The point is, the object Row() can receive a **kwargs argument. So, there is an easy way to do that.

from pyspark.sql.types import Row

#here you are going to create a function
def f(x):
    d = {}
    for i in range(len(x)):
        d[str(i)] = x[i]
    return d

#Now populate that
df = rdd.map(lambda x: Row(**f(x))).toDF()

This way you are going to be able to create a dataframe dynamically.

createDataFrame(rdd, schema)

Other way to do that is creating a dynamic schema. How?

This way:

from pyspark.sql.types import StructType
from pyspark.sql.types import StructField
from pyspark.sql.types import StringType

schema = StructType([StructField(str(i), StringType(), True) for i in range(32)])

df = sqlContext.createDataFrame(rdd, schema)

This second way is cleaner to do that...

So this is how you can create dataframes dynamically.

I had this problem and tried everything here but it didn't help. Then I noticed that the cord I was using was a little frayed, so I tried a new cord and it worked.

1. Highlight the column with the name
2. Data > Pivot Table and Pivot Chart
3. Next, Next layout
4. drag the column title to the row section
5. drag it again to the data section
6. Ok > Finish

Solution:
Instead of using setHeader method I have used addHeader.

response.addHeader("Access-Control-Allow-Origin", "*");

* in above line will allow access to all domains, For allowing access to specific domain only:

response.addHeader("Access-Control-Allow-Origin", "http://www.example.com");

For issues related to IE<=9, Please see here.

I think you mean SqlServer but on Oracle you have a hard limit how many IN elements you can specify: 1000.

set the variable on window:

window.a_href = a_href;

Use std::make_pair:

revenue.push_back(std::make_pair("string",map[i].second));

Check this:

<?php
if (mysqli_num_rows(mysqli_query($con, sqlselectquery)) > 0)
{
    echo "found";
}
else
{
    echo "not found";
}
?>

<!----comment ---for select query to know row matching the condition are fetched or not--->

This is essentially the answer that Yishai provided above, re-written in Kotlin :

@RunWith(Parameterized::class)
class MyTest {

    companion object {

        private const val numberOfTests = 200

        @JvmStatic
        @Parameterized.Parameters
        fun data(): Array<Array<Any?>> = Array(numberOfTests) { arrayOfNulls<Any?>(0) }
    }

    @Test
    fun testSomething() { }
}

Which method is used to check if SESSION exists or not? Answer:

isset($_SESSION['variable_name'])

Example:

isset($_SESSION['id'])

Content insets solve the problem of having content that goes underneath other parts of the User Interface and yet still remains reachable using scroll bars. In other words, the purpose of the Content Inset is to make the interaction area smaller than its actual area.

Consider the case where we have three logical areas of the screen:

TOP BUTTONS

TEXT

BOTTOM TAB BAR

and we want the TEXT to never appear transparently underneath the TOP BUTTONS, but we want the Text to appear underneath the BOTTOM TAB BAR and yet still allow scrolling so we could update the text sitting transparently under the BOTTOM TAB BAR.

Then we would set the top origin to be below the TOP BUTTONS, and the height to include the bottom of BOTTOM TAB BAR. To gain access to the Text sitting underneath the BOTTOM TAB BAR content we would set the bottom inset to be the height of the BOTTOM TAB BAR.

Without the inset, the scroller would not let you scroll up the content enough to type into it. With the inset, it is as if the content had extra "BLANK CONTENT" the size of the content inset. Blank text has been "inset" into the real "content" -- that's how I remember the concept.

A problem with all of the above is that the conversion returns the incorrect number of days as specified in the TimeSpan.
Using the above, the below returns 3 and not 2.

Ideas on how to preserve the 2 days in the TimeSpan arguments and return them as the DateTime day?

public void should_return_totaldays()
{
    _ts = new TimeSpan(2, 1, 30, 10);
    var format = "dd";
    var returnedVal = _ts.ToString(format);
    Assert.That(returnedVal, Is.EqualTo("2")); //returns 3 not 2
}

Use ldapsearch to authenticate. The opends version might be used as follows:

ldapsearch --hostname hostname --port port \
    --bindDN userdn --bindPassword password \
    --baseDN '' --searchScope base 'objectClass=*' 1.1

I find converting to the binary representation easier to grasp this problem.

float f = 0.27f;
double d2 = (double) f;
double d3 = 0.27d;

System.out.println(Integer.toBinaryString(Float.floatToRawIntBits(f)));
System.out.println(Long.toBinaryString(Double.doubleToRawLongBits(d2)));
System.out.println(Long.toBinaryString(Double.doubleToRawLongBits(d3)));

You can see the float is expanded to the double by adding 0s to the end, but that the double representation of 0.27 is 'more accurate', hence the problem.

Just adding

left:15%; 

into my css menu of

#menu li {
float: left;
position:relative;
left: 15%;
list-style:none;
}

did the centering trick too

Here is answer for your question.

db.getCollection('users').aggregate([
    {$match : {admin : 1}},
    {$lookup: {from: "posts",localField: "_id",foreignField: "owner_id",as: "posts"}},
    {$project : {
            posts : { $filter : {input : "$posts"  , as : "post", cond : { $eq : ['$$post.via' , 'facebook'] } } },
            admin : 1

        }}

])

Or either you can go with mongodb group option.

db.getCollection('users').aggregate([
    {$match : {admin : 1}},
    {$lookup: {from: "posts",localField: "_id",foreignField: "owner_id",as: "posts"}},
    {$unwind : "$posts"},
    {$match : {"posts.via":"facebook"}},
    { $group : {
            _id : "$_id",
            posts : {$push : "$posts"}
    }}
])

Remove both http and https setting by using commands.

git config --global --unset http.proxy

git config --global --unset https.proxy

I found that:

git log --reverse

shows commits from start.

The simplest way to produce these dummy variables is something like the following:

> print(year)
[1] 1956 1957 1957 1958 1958 1959
> dummy <- as.numeric(year == 1957)
> print(dummy)
[1] 0 1 1 0 0 0
> dummy2 <- as.numeric(year >= 1957)
> print(dummy2)
[1] 0 1 1 1 1 1

More generally, you can use ifelse to choose between two values depending on a condition. So if instead of a 0-1 dummy variable, for some reason you wanted to use, say, 4 and 7, you could use ifelse(year == 1957, 4, 7).

You could try a global table:

create table ##global_var
            (var1 int
            ,var2 int)

USE "DB_1"
GO
SELECT * FROM "TABLE" WHERE "COL_!" = (select var1 from ##global_var) 

AND "COL_2" = @GLOBAL_VAR_2

USE "DB_2"
GO

SELECT * FROM "TABLE" WHERE "COL_!" = (select var2 from ##global_var) 

For some reason, the above answer did not work for me; I did not return to the command prompt after running it as I expected with the trailing &. Instead, I simply tried with

nohup some_command > nohup2.out&

and it works just as I want it to. Leaving this here in case someone else is in the same situation. Running Bash 4.3.8 for reference.

1) If the Map can be immutable:

Collections.emptyMap()

// or, in some cases:
Collections.<String, String>emptyMap()

You'll have to use the latter sometimes when the compiler cannot automatically figure out what kind of Map is needed (this is called type inference). For example, consider a method declared like this:

public void foobar(Map<String, String> map){ ... }

When passing the empty Map directly to it, you have to be explicit about the type:

foobar(Collections.emptyMap());                 // doesn't compile
foobar(Collections.<String, String>emptyMap()); // works fine

2) If you need to be able to modify the Map, then for example:

new HashMap<String, String>()

(as tehblanx pointed out)

Addendum: If your project uses Guava, you have the following alternatives:

1) Immutable map:

ImmutableMap.of()
// or:
ImmutableMap.<String, String>of()

Granted, no big benefits here compared to Collections.emptyMap(). From the Javadoc:

This map behaves and performs comparably to Collections.emptyMap(), and is preferable mainly for consistency and maintainability of your code.

2) Map that you can modify:

Maps.newHashMap()
// or:
Maps.<String, String>newHashMap()

Maps contains similar factory methods for instantiating other types of maps as well, such as TreeMap or LinkedHashMap.

Update (2018): On Java 9 or newer, the shortest code for creating an immutable empty map is:

Map.of()

...using the new convenience factory methods from JEP 269.

Stumbled upon this one but you can get it by using the following as long as you import numpy.

import numpy as np

[y, x] = np.shape(img[:,:,0])

It works because you ignore all but one color and then the image is just 2D so shape tells you how bid it is. Still kinda new to Python but seems like a simple way to do it.

For string delimiter

Split string based on a string delimiter. Such as splitting string "adsf-+qwret-+nvfkbdsj-+orthdfjgh-+dfjrleih" based on string delimiter "-+", output will be {"adsf", "qwret", "nvfkbdsj", "orthdfjgh", "dfjrleih"}

#include <iostream>
#include <sstream>
#include <vector>

using namespace std;

// for string delimiter
vector<string> split (string s, string delimiter) {
    size_t pos_start = 0, pos_end, delim_len = delimiter.length();
    string token;
    vector<string> res;

    while ((pos_end = s.find (delimiter, pos_start)) != string::npos) {
        token = s.substr (pos_start, pos_end - pos_start);
        pos_start = pos_end + delim_len;
        res.push_back (token);
    }

    res.push_back (s.substr (pos_start));
    return res;
}

int main() {
    string str = "adsf-+qwret-+nvfkbdsj-+orthdfjgh-+dfjrleih";
    string delimiter = "-+";
    vector<string> v = split (str, delimiter);

    for (auto i : v) cout << i << endl;

    return 0;
}

Output

adsf
qwret
nvfkbdsj
orthdfjgh
dfjrleih

For single character delimiter

Split string based on a character delimiter. Such as splitting string "adsf+qwer+poui+fdgh" with delimiter "+" will output {"adsf", "qwer", "poui", "fdg"h}

#include <iostream>
#include <sstream>
#include <vector>

using namespace std;

vector<string> split (const string &s, char delim) {
    vector<string> result;
    stringstream ss (s);
    string item;

    while (getline (ss, item, delim)) {
        result.push_back (item);
    }

    return result;
}

int main() {
    string str = "adsf+qwer+poui+fdgh";
    vector<string> v = split (str, '+');

    for (auto i : v) cout << i << endl;

    return 0;
}

Output

adsf
qwer
poui
fdgh

Another workaround, not beautiful buy workable.

I have an XML file with an element called "MEMDES" with two attribute as "GRADE" and "SPD" to record the RAM module information. There are lot of dupelicate items in SPD.

So here is the code I use to remove the dupelicated items:

        IEnumerable<XElement> MList =
            from RAMList in PREF.Descendants("MEMDES")
            where (string)RAMList.Attribute("GRADE") == "DDR4"
            select RAMList;

        List<string> sellist = new List<string>();

        foreach (var MEMList in MList)
        {
            sellist.Add((string)MEMList.Attribute("SPD").Value);
        }

        foreach (string slist in sellist.Distinct())
        {
            comboBox1.Items.Add(slist);
        }

hwloc (http://www.open-mpi.org/projects/hwloc/) is worth looking at. Though requires another library integration into your code but it can provide all the information about your processor (number of cores, the topology, etc.)

This would change all the occurrences of those letters in all names:

 names(x) <- gsub("q", "A", gsub("e", "B", names(x) ) )

Data-Binding

You go around making your webpage, and keep on putting {{data bindings}} whenever you feel you would have dynamic data. Angular will then provide you a $scope handler, which you can populate (statically or through calls to the web server).

This is a good understanding of data-binding. I think you've got that down.

DOM Manipulation

For simple DOM manipulation, which doesnot involve data manipulation (eg: color changes on mousehover, hiding/showing elements on click), jQuery or old-school js is sufficient and cleaner. This assumes that the model in angular's mvc is anything that reflects data on the page, and hence, css properties like color, display/hide, etc changes dont affect the model.

I can see your point here about "simple" DOM manipulation being cleaner, but only rarely and it would have to be really "simple". I think DOM manipulation is one the areas, just like data-binding, where Angular really shines. Understanding this will also help you see how Angular considers its views.

I'll start by comparing the Angular way with a vanilla js approach to DOM manipulation. Traditionally, we think of HTML as not "doing" anything and write it as such. So, inline js, like "onclick", etc are bad practice because they put the "doing" in the context of HTML, which doesn't "do". Angular flips that concept on its head. As you're writing your view, you think of HTML as being able to "do" lots of things. This capability is abstracted away in angular directives, but if they already exist or you have written them, you don't have to consider "how" it is done, you just use the power made available to you in this "augmented" HTML that angular allows you to use. This also means that ALL of your view logic is truly contained in the view, not in your javascript files. Again, the reasoning is that the directives written in your javascript files could be considered to be increasing the capability of HTML, so you let the DOM worry about manipulating itself (so to speak). I'll demonstrate with a simple example.

This is the markup we want to use. I gave it an intuitive name.

<div rotate-on-click="45"></div>

First, I'd just like to comment that if we've given our HTML this functionality via a custom Angular Directive, we're already done. That's a breath of fresh air. More on that in a moment.

Implementation with jQuery

live demo here (click).

function rotate(deg, elem) {
  $(elem).css({
    webkitTransform: 'rotate('+deg+'deg)', 
    mozTransform: 'rotate('+deg+'deg)', 
    msTransform: 'rotate('+deg+'deg)', 
    oTransform: 'rotate('+deg+'deg)', 
    transform: 'rotate('+deg+'deg)'    
  });
}

function addRotateOnClick($elems) {
  $elems.each(function(i, elem) {
    var deg = 0;
    $(elem).click(function() {
      deg+= parseInt($(this).attr('rotate-on-click'), 10);
      rotate(deg, this);
    });
  });
}

addRotateOnClick($('[rotate-on-click]'));

Implementation with Angular

live demo here (click).

app.directive('rotateOnClick', function() {
  return {
    restrict: 'A',
    link: function(scope, element, attrs) {
      var deg = 0;
      element.bind('click', function() {
        deg+= parseInt(attrs.rotateOnClick, 10);
        element.css({
          webkitTransform: 'rotate('+deg+'deg)', 
          mozTransform: 'rotate('+deg+'deg)', 
          msTransform: 'rotate('+deg+'deg)', 
          oTransform: 'rotate('+deg+'deg)', 
          transform: 'rotate('+deg+'deg)'    
        });
      });
    }
  };
});

Pretty light, VERY clean and that's just a simple manipulation! In my opinion, the angular approach wins in all regards, especially how the functionality is abstracted away and the dom manipulation is declared in the DOM. The functionality is hooked onto the element via an html attribute, so there is no need to query the DOM via a selector, and we've got two nice closures - one closure for the directive factory where variables are shared across all usages of the directive, and one closure for each usage of the directive in the link function (or compile function).

Two-way data binding and directives for DOM manipulation are only the start of what makes Angular awesome. Angular promotes all code being modular, reusable, and easily testable and also includes a single-page app routing system. It is important to note that jQuery is a library of commonly needed convenience/cross-browser methods, but Angular is a full featured framework for creating single page apps. The angular script actually includes its own "lite" version of jQuery so that some of the most essential methods are available. Therefore, you could argue that using Angular IS using jQuery (lightly), but Angular provides much more "magic" to help you in the process of creating apps.

This is a great post for more related information: How do I “think in AngularJS” if I have a jQuery background?

General differences.

The above points are aimed at the OP's specific concerns. I'll also give an overview of the other important differences. I suggest doing additional reading about each topic as well.

Angular and jQuery can't reasonably be compared.

Angular is a framework, jQuery is a library. Frameworks have their place and libraries have their place. However, there is no question that a good framework has more power in writing an application than a library. That's exactly the point of a framework. You're welcome to write your code in plain JS, or you can add in a library of common functions, or you can add a framework to drastically reduce the code you need to accomplish most things. Therefore, a more appropriate question is:

Why use a framework?

Good frameworks can help architect your code so that it is modular (therefore reusable), DRY, readable, performant and secure. jQuery is not a framework, so it doesn't help in these regards. We've all seen the typical walls of jQuery spaghetti code. This isn't jQuery's fault - it's the fault of developers that don't know how to architect code. However, if the devs did know how to architect code, they would end up writing some kind of minimal "framework" to provide the foundation (achitecture, etc) I discussed a moment ago, or they would add something in. For example, you might add RequireJS to act as part of your framework for writing good code.

Here are some things that modern frameworks are providing:

• Templating
• Data-binding
• routing (single page app)
• clean, modular, reusable architecture
• security
• additional functions/features for convenience

Before I further discuss Angular, I'd like to point out that Angular isn't the only one of its kind. Durandal, for example, is a framework built on top of jQuery, Knockout, and RequireJS. Again, jQuery cannot, by itself, provide what Knockout, RequireJS, and the whole framework built on top them can. It's just not comparable.

If you need to destroy a planet and you have a Death Star, use the Death star.

Angular (revisited).

Building on my previous points about what frameworks provide, I'd like to commend the way that Angular provides them and try to clarify why this is matter of factually superior to jQuery alone.

DOM reference.

In my above example, it is just absolutely unavoidable that jQuery has to hook onto the DOM in order to provide functionality. That means that the view (html) is concerned about functionality (because it is labeled with some kind of identifier - like "image slider") and JavaScript is concerned about providing that functionality. Angular eliminates that concept via abstraction. Properly written code with Angular means that the view is able to declare its own behavior. If I want to display a clock:

<clock></clock>

Done.

Yes, we need to go to JavaScript to make that mean something, but we're doing this in the opposite way of the jQuery approach. Our Angular directive (which is in it's own little world) has "augumented" the html and the html hooks the functionality into itself.

MVW Architecure / Modules / Dependency Injection

Angular gives you a straightforward way to structure your code. View things belong in the view (html), augmented view functionality belongs in directives, other logic (like ajax calls) and functions belong in services, and the connection of services and logic to the view belongs in controllers. There are some other angular components as well that help deal with configuration and modification of services, etc. Any functionality you create is automatically available anywhere you need it via the Injector subsystem which takes care of Dependency Injection throughout the application. When writing an application (module), I break it up into other reusable modules, each with their own reusable components, and then include them in the bigger project. Once you solve a problem with Angular, you've automatically solved it in a way that is useful and structured for reuse in the future and easily included in the next project. A HUGE bonus to all of this is that your code will be much easier to test.

It isn't easy to make things "work" in Angular.

THANK GOODNESS. The aforementioned jQuery spaghetti code resulted from a dev that made something "work" and then moved on. You can write bad Angular code, but it's much more difficult to do so, because Angular will fight you about it. This means that you have to take advantage (at least somewhat) to the clean architecture it provides. In other words, it's harder to write bad code with Angular, but more convenient to write clean code.

Angular is far from perfect. The web development world is always growing and changing and there are new and better ways being put forth to solve problems. Facebook's React and Flux, for example, have some great advantages over Angular, but come with their own drawbacks. Nothing's perfect, but Angular has been and is still awesome for now. Just as jQuery once helped the web world move forward, so has Angular, and so will many to come.

If you are using Java, you could just replace the x00 characters before the insert like following:

myValue.replaceAll("\u0000", "")

The solution was provided and explained by Csaba in following post:

https://www.postgresql.org/message-id/1171970019.3101.328.camel%40coppola.muc.ecircle.de

Respectively:

in Java you can actually have a "0x0" character in your string, and that's valid unicode. So that's translated to the character 0x0 in UTF8, which in turn is not accepted because the server uses null terminated strings... so the only way is to make sure your strings don't contain the character '\u0000'.

You could use the Add-Content cmdlet. Maybe it is a little faster than the other solutions, because I don't retrieve the content of the first file.

gc .\file2.txt| Add-Content -Path .\file1.txt

Maybe I'm missing something, but why try to parse the file? Why not just load the YAML and examine the object(s) that result?

If your sample YAML is in some.yml, then this:

require 'yaml'
thing = YAML.load_file('some.yml')
puts thing.inspect

gives me

{"javascripts"=>[{"fo_global"=>["lazyload-min", "holla-min"]}]}

Do not use @@fetch_status - this will return status from the last cursor in the current connection. Use the example below:

declare @sqCur cursor;
declare @data varchar(1000);
declare @i int = 0, @lastNum int, @rowNum int;
set @sqCur = cursor local static read_only for 
    select
         row_number() over (order by(select null)) as RowNum
        ,Data -- you fields
    from YourIntTable
open @cur
begin try
    fetch last from @cur into @lastNum, @data
    fetch absolute 1 from @cur into @rowNum, @data --start from the beginning and get first value 
    while @i < @lastNum
    begin
        set @i += 1

        --Do your job here
        print @data

        fetch next from @cur into @rowNum, @data
    end
end try
begin catch
    close @cur      --|
    deallocate @cur --|-remove this 3 lines if you do not throw
    ;throw          --|
end catch
close @cur
deallocate @cur

You can try the %v, %+v or %#v verbs of go fmt:

fmt.Printf("%v", projects)

If your array (or here slice) contains struct (like Project), you will see their details.
For more precision, you can use %#v to print the object using Go-syntax, as for a literal:

%v  the value in a default format.
    when printing structs, the plus flag (%+v) adds field names
%#v a Go-syntax representation of the value

For basic types, fmt.Println(projects) is enough.

Note: for a slice of pointers, that is []*Project (instead of []Project), you are better off defining a String() method in order to display exactly what you want to see (or you will see only pointer address).
See this play.golang example.

Have you tried using a icon font like http://fortawesome.github.io/Font-Awesome/

Bootstrap comes with their own library, but it doesn't have as many icons as Font Awesome.

http://getbootstrap.com/components/#glyphicons

I used https://iconifier.net I uploaded my image, downloaded images zip file, added images to my server, followed the directions on the site including adding the links to my index.html and it worked. My favicon now shows on my iPhone in Safari when 'Add to home screen'

If you do not find interest in overriding save method, you can do

  model_fields = [f.name for f in YourModel._meta.get_fields()]
  valid_data = {
        key: new_data[key]
        for key in model_fields
        if key in new_data.keys()
  }

  for (key, value) in valid_data.items():
        if getattr(instance, key) != value:
           print ('Data has changed')

        setattr(instance, key, value)

 instance.save()

One possible reason of why scroll.fullScroll(View.FOCUS_DOWN) might not work even wrapped in .post() is that the view is not laid out. In this case View.doOnLayout() could be a better option:

scroll.doOnLayout(){
    scroll.fullScroll(View.FOCUS_DOWN)
}

Or, something more elaborated for the brave souls: https://chris.banes.dev/2019/12/03/suspending-views/

This works for me, I hope helps to someone.

var frm = $('#frm');
let formData = new FormData(frm[0]);
axios.post('your-url', formData)
    .then(res => {
        console.log({res});
    }).catch(err => {
        console.error({err});
    });

Boost has something to help: the Boost.Iterator library.

More precisely this page: boost::iterator_adaptor.

What's very interesting is the Tutorial Example which shows a complete implementation, from scratch, for a custom type.

template <class Value>
class node_iter
  : public boost::iterator_adaptor<
        node_iter<Value>                // Derived
      , Value*                          // Base
      , boost::use_default              // Value
      , boost::forward_traversal_tag    // CategoryOrTraversal
    >
{
 private:
    struct enabler {};  // a private type avoids misuse

 public:
    node_iter()
      : node_iter::iterator_adaptor_(0) {}

    explicit node_iter(Value* p)
      : node_iter::iterator_adaptor_(p) {}

    // iterator convertible to const_iterator, not vice-versa
    template <class OtherValue>
    node_iter(
        node_iter<OtherValue> const& other
      , typename boost::enable_if<
            boost::is_convertible<OtherValue*,Value*>
          , enabler
        >::type = enabler()
    )
      : node_iter::iterator_adaptor_(other.base()) {}

 private:
    friend class boost::iterator_core_access;
    void increment() { this->base_reference() = this->base()->next(); }
};

The main point, as has been cited already, is to use a single template implementation and typedef it.

I have done below steps. finally it's working fine.

Steps

1) git init

2) git status (for checking status)

3) git add . (add all the change file (.))

4) git commit -m "<pass your comment>"

5) git remote add origin "<pass your project clone url>"

6) git pull --allow-unrelated-histories "<pass your project clone url>" master

7) git push -u "<pass your project clone url>" master

You cannot use the datetime function using the Java wrapper "ContentValues". Either you can use :

• SQLiteDatabase.execSQL so you can enter a raw SQL query.

  mDb.execSQL("INSERT INTO "+DATABASE_TABLE+" VALUES (null, datetime()) ");
  

• Or the java date time capabilities :

  // set the format to sql date time
  SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 
  Date date = new Date();
  ContentValues initialValues = new ContentValues(); 
  initialValues.put("date_created", dateFormat.format(date));
  long rowId = mDb.insert(DATABASE_TABLE, null, initialValues);
  

I had the same problem except I did not know in advance what were the thousands separators and the decimal separator. I ended up writing a library to do this. If you are interested it here it is : https://github.com/GuillaumeLeclerc/number-parsing

If you have several threads executing the methods m1 and m2 in the code below:

class SomeClass {
    private int i = 0;

    public void m1() { i = 5; }
    public int m2() { return i; }
}

you have the guarantee that any thread calling m2 will either read 0 or 5.

On the other hand, with this code (where i is a long):

class SomeClass {
    private long i = 0;

    public void m1() { i = 1234567890L; }
    public long m2() { return i; }
}

a thread calling m2 could read 0, 1234567890L, or some other random value because the statement i = 1234567890L is not guaranteed to be atomic for a long (a JVM could write the first 32 bits and the last 32 bits in two operations and a thread might observe i in between).

The most widely compatible way of doing this is likely going to be creating a second div under your auto-suggest box the same size as the box itself, nudged a few pixels down and to the right. You can use JS to create and position it, which shouldn't be terribly difficult if you're using a fairly modern framework.

If the keystore is for tomcat then, after creating the keystore with the above answers, you must add a final step to create the "tomcat" alias for the key:

keytool -changealias -alias "1" -destalias "tomcat" -keystore keystore-file.jks

You can check the result with:

keytool -list -keystore keystore-file.jks -v

I had a similar problem and solved it by checking the threads that are running. To see the running threads use the following command in mysql command line interface:

SHOW PROCESSLIST;

It can also be sent from phpMyAdmin if you don't have access to mysql command line interface.
This will display a list of threads with corresponding ids and execution time, so you can KILL the threads that are taking too much time to execute. In phpMyAdmin you will have a button for stopping threads by using KILL, if you are using command line interface just use the KILL command followed by the thread id, like in the following example:

KILL 115;

This will terminate the connection for the corresponding thread.

Just run below command with admin access

npm install --global --production windows-build-tools

By using regular expression: $string = preg_replace('/\s+By.*$/', '', $string)

give width as 0dp to make sure its size is exactly as per its weight this will make sure that even if content of child views get bigger, they'll still be limited to exactly half(according to is weight)

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:weightSum="1"
     >

    <Button
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:text="click me"
    android:layout_weight="0.5"/>


    <TextView
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:text="Hello World"
    android:layout_weight="0.5"/>
  </LinearLayout>

When using the $array.Add()-method, you're trying to add the element into the existing array. An array is a collection of fixed size, so you will receive an error because it can't be extended.

$array += $element creates a new array with the same elements as old one + the new item, and this new larger array replaces the old one in the $array-variable

You can use the += operator to add an element to an array. When you use it, Windows PowerShell actually creates a new array with the values of the original array and the added value. For example, to add an element with a value of 200 to the array in the $a variable, type:

    $a += 200

Source: about_Arrays

+= is an expensive operation, so when you need to add many items you should try to add them in as few operations as possible, ex:

$arr = 1..3    #Array
$arr += (4..5) #Combine with another array in a single write-operation

$arr.Count
5

If that's not possible, consider using a more efficient collection like List or ArrayList (see the other answer).

Use this:

document.getElementById(target).value = newVal.replace(/[^0-9.]/g, '');

CREATE FUNCTION ActionState_Preassigned()
RETURNS tinyint
AS
BEGIN
    RETURN 0
END

GO

CREATE FUNCTION ActionState_Unassigned()
RETURNS tinyint
AS
BEGIN
    RETURN 1
END

-- etc...

Where performance matters, still use the hard values.

Just one space or all consecutive spaces? If the second, then strings already have a .strip() method:

>>> ' Hello '.strip()
'Hello'
>>> ' Hello'.strip()
'Hello'
>>> 'Bob has a cat'.strip()
'Bob has a cat'
>>> '   Hello   '.strip()  # ALL consecutive spaces at both ends removed
'Hello'

If you only need to remove one space however, you could do it with:

def strip_one_space(s):
    if s.endswith(" "): s = s[:-1]
    if s.startswith(" "): s = s[1:]
    return s

>>> strip_one_space("   Hello ")
'  Hello'

Also, note that str.strip() removes other whitespace characters as well (e.g. tabs and newlines). To remove only spaces, you can specify the character to remove as an argument to strip, i.e.:

>>> "  Hello\n".strip(" ")
'Hello\n'

you can do it as follow:

 $("#addButton").click(function () {

    if(counter>10){
            alert("Only 10 textboxes allow");
            return false;
    }   

    var newTextBoxDiv = $(document.createElement('div'))
         .attr("id", 'TextBoxDiv' + counter);

    newTextBoxDiv.after().html('<label>Textbox #'+ counter + ' : </label>' +
          '<input type="text" name="textbox' + counter + 
          '" id="textbox' + counter + '" value="" >');

    newTextBoxDiv.appendTo("#TextBoxesGroup");


    counter++;
     });

     $("#removeButton").click(function () {
    if(counter==1){
          alert("No more textbox to remove");
          return false;
       }   

    counter--;

        $("#TextBoxDiv" + counter).remove();

     });

If you're trying to query an Oracle database, you might want to use

select owner, table_name 
from all_tab_columns
where column_name = 'ColName';

Just use standard CSS variables:

Your global css (eg: styles.css)

body {
  --my-var: #000
}

In your component's css or whatever it is:

span {
  color: var(--my-var)
}

Then you can change the value of the variable directly with TS/JS by setting inline style to html element:

document.querySelector("body").style.cssText = "--my-var: #000";

Otherwise you can use jQuery for it:

$("body").css("--my-var", "#fff");

There is not really any other way in JavaScript to concatenate strings.
You could theoretically use .concat(), but that's way slower than just +

Libraries are more often than not slower than native JavaScript, especially on basic operations like string concatenation, or numerical operations.

Simply put: + is the fastest.

Use #pragma warning ( push ), then #pragma warning ( disable ), then put your code, then use #pragma warning ( pop ) as described here:

#pragma warning( push )
#pragma warning( disable : WarningCode)
// code with warning
#pragma warning( pop ) 

I've found that in the majority of cases doing block clauses on one line is a bad idea.

It will, again as a generality, reduce the quality of the form of the code. High quality code form is a key language feature for python.

In some cases python will offer ways todo things on one line that are definitely more pythonic. Things such as what Nick D mentioned with the list comprehension:

newlist = [splitColon.split(a) for a in someList]

although unless you need a reusable list specifically you may want to consider using a generator instead

listgen = (splitColon.split(a) for a in someList)

note the biggest difference between the two is that you can't reiterate over a generator, but it is more efficient to use.

There is also a built in ternary operator in modern versions of python that allow you to do things like

string_to_print = "yes!" if "exam" in "example" else ""
print string_to_print

or

iterator = max_value if iterator > max_value else iterator

Some people may find these more readable and usable than the similar if (condition): block.

When it comes down to it, it's about code style and what's the standard with the team you're working on. That's the most important, but in general, i'd advise against one line blocks as the form of the code in python is so very important.

Open the CSV file with a decent text editor like Notepad++ and add the following text in the first line:

sep=,

Now open it with excel again.

This will set the separator as a comma, or you can change it to whatever you need.

For this to work, your font also needs to be set to monospace.
If you think about it, lines can't otherwise line up perfectly perfectly.

How to generate a random point within a circle of radius R:

r = R * sqrt(random())
theta = random() * 2 * PI

(Assuming random() gives a value between 0 and 1 uniformly)

If you want to convert this to Cartesian coordinates, you can do

x = centerX + r * cos(theta)
y = centerY + r * sin(theta)

Why sqrt(random())?

Let's look at the math that leads up to sqrt(random()). Assume for simplicity that we're working with the unit circle, i.e. R = 1.

The average distance between points should be the same regardless of how far from the center we look. This means for example, that looking on the perimeter of a circle with circumference 2 we should find twice as many points as the number of points on the perimeter of a circle with circumference 1.

Since the circumference of a circle (2πr) grows linearly with r, it follows that the number of random points should grow linearly with r. In other words, the desired probability density function (PDF) grows linearly. Since a PDF should have an area equal to 1 and the maximum radius is 1, we have

So we know how the desired density of our random values should look like. Now: How do we generate such a random value when all we have is a uniform random value between 0 and 1?

We use a trick called inverse transform sampling

1. From the PDF, create the cumulative distribution function (CDF)
2. Mirror this along y = x
3. Apply the resulting function to a uniform value between 0 and 1.

Sounds complicated? Let me insert a blockquote with a little side track that conveys the intuition:

Suppose we want to generate a random point with the following distribution:

                

That is

• 1/5 of the points uniformly between 1 and 2, and
• 4/5 of the points uniformly between 2 and 3.

The CDF is, as the name suggests, the cumulative version of the PDF. Intuitively: While PDF(x) describes the number of random values at x, CDF(x) describes the number of random values less than x.

In this case the CDF would look like:

                

To see how this is useful, imagine that we shoot bullets from left to right at uniformly distributed heights. As the bullets hit the line, they drop down to the ground:

                

See how the density of the bullets on the ground correspond to our desired distribution! We're almost there!

The problem is that for this function, the y axis is the output and the x axis is the input. We can only "shoot bullets from the ground straight up"! We need the inverse function!

This is why we mirror the whole thing; x becomes y and y becomes x:

                

We call this CDF^-1. To get values according to the desired distribution, we use CDF^-1(random()).

…so, back to generating random radius values where our PDF equals 2x.

Step 1: Create the CDF:

Since we're working with reals, the CDF is expressed as the integral of the PDF.

CDF(x) = ? 2x = x²

Step 2: Mirror the CDF along y = x:

Mathematically this boils down to swapping x and y and solving for y:

CDF:     y = x²
Swap:   x = y²
Solve:   y = √x
CDF^-1:  y = √x

Step 3: Apply the resulting function to a uniform value between 0 and 1

CDF^-1(random()) = √random()

Which is what we set out to derive :-)

var timestamp = DateTime.Now.ToFileTime();

//output: 132260149842749745

This is an alternative way to individuate distinct transactions. It's not unix time, but windows filetime.

From the docs:

A Windows file time is a 64-bit value that represents the number of 100- 
nanosecond intervals that have elapsed since 12:00 midnight, January 1, 1601 
A.D. (C.E.) Coordinated Universal Time (UTC).

var Text = File.ReadAllLines("Path"); foreach (var i in Text) {    var SplitText = i.Split().Where(x=> x.Lenght>1).ToList();    //@Array1 add SplitText[0]    //@Array2 add SpliteText[1]   }  

I prefer using HTTP Headers for this kind of contextual information.

For the total number of elements, I use the X-total-count header.
For links to next, previous page, etc. I use HTTP Link header:
http://www.w3.org/wiki/LinkHeader

Github does it the same way: https://developer.github.com/v3/#pagination

In my opinion, it's cleaner since it can be used also when you return content that doesn't support hyperlinks (i.e binaries, pictures).

JPA is just a specification which needs concrete implementation. The default implementation oracle provide is "Eclipselink" now. (Toplink is donated by Oracle to Eclipse foundation to merge with eclipselink)

(Reference : http://www.oracle.com/technetwork/middleware/toplink/index-085257.html http://www.eclipse.org/org/press-release/20080317_Eclipselink.php )

Using Eclipselink, one can be sure that the code is portable to any implementation if need arises. Hibernate is also a full JPA implementation + MORE ( Sort of JPA Plus). Hibernate is super set of JPA with some extra Hibernate specific functionality. So app developed in Hibernate may not be compatible when switched to other implementation. Still hibernate is choice of majority of developers as JPA implementation and widely used.

Another JPA implementation is OpenJPA (openjpa.apache.org) which is an extension of Kodo implementation.

Directed graph:

Question: What's the maximum number of edges in a directed graph with n vertices?

• Assume there are no self-loops.
• Assume there there is at most one edge from a given start vertex to a given end vertex.

Each edge is specified by its start vertex and end vertex. There are n choices for the start vertex. Since there are no self-loops, there are n-1 choices for the end vertex. Multiplying these together counts all possible choices.

Answer: n(n-1)

Undirected graph

Question: What's the maximum number of edges in an undirected graph with n vertices?

• Assume there are no self-loops.
• Assume there there is at most one edge from a given start vertex to a given end vertex.

In an undirected graph, each edge is specified by its two endpoints and order doesn't matter. The number of edges is therefore the number of subsets of size 2 chosen from the set of vertices. Since the set of vertices has size n, the number of such subsets is given by the binomial coefficient C(n,2) (also known as "n choose 2"). Using the formula for binomial coefficients, C(n,2) = n(n-1)/2.

Answer: (n*(n-1))/2

Update: Given that this post is quite old, and I've modified this utility a lot for my own use during that time, I thought I should post a new version. My newest code can be found on The MathWorks File Exchange: dirPlus.m. You can also get the source from GitHub.

I made a number of improvements. It now gives you options to prepend the full path or return just the file name (incorporated from Doresoom and Oz Radiano) and apply a regular expression pattern to the file names (incorporated from Peter D). In addition, I added the ability to apply a validation function to each file, allowing you to select them based on criteria other than just their names (i.e. file size, content, creation date, etc.).

NOTE: In newer versions of MATLAB (R2016b and later), the dir function has recursive search capabilities! So you can do this to get a list of all *.m files in all subfolders of the current folder:

dirData = dir('**/*.m');

Old code: (for posterity)

Here's a function that searches recursively through all subdirectories of a given directory, collecting a list of all file names it finds:

function fileList = getAllFiles(dirName)

  dirData = dir(dirName);      %# Get the data for the current directory
  dirIndex = [dirData.isdir];  %# Find the index for directories
  fileList = {dirData(~dirIndex).name}';  %'# Get a list of the files
  if ~isempty(fileList)
    fileList = cellfun(@(x) fullfile(dirName,x),...  %# Prepend path to files
                       fileList,'UniformOutput',false);
  end
  subDirs = {dirData(dirIndex).name};  %# Get a list of the subdirectories
  validIndex = ~ismember(subDirs,{'.','..'});  %# Find index of subdirectories
                                               %#   that are not '.' or '..'
  for iDir = find(validIndex)                  %# Loop over valid subdirectories
    nextDir = fullfile(dirName,subDirs{iDir});    %# Get the subdirectory path
    fileList = [fileList; getAllFiles(nextDir)];  %# Recursively call getAllFiles
  end

end

After saving the above function somewhere on your MATLAB path, you can call it in the following way:

fileList = getAllFiles('D:\dic');

I highly recommend the book "Pro Git" by Scott Chacon. Take time and really read it, while exploring an actual git repo as you do.

HEAD: the current commit your repo is on. Most of the time HEAD points to the latest commit in your current branch, but that doesn't have to be the case. HEAD really just means "what is my repo currently pointing at".

In the event that the commit HEAD refers to is not the tip of any branch, this is called a "detached head".

master: the name of the default branch that git creates for you when first creating a repo. In most cases, "master" means "the main branch". Most shops have everyone pushing to master, and master is considered the definitive view of the repo. But it's also common for release branches to be made off of master for releasing. Your local repo has its own master branch, that almost always follows the master of a remote repo.

origin: the default name that git gives to your main remote repo. Your box has its own repo, and you most likely push out to some remote repo that you and all your coworkers push to. That remote repo is almost always called origin, but it doesn't have to be.

HEAD is an official notion in git. HEAD always has a well-defined meaning. master and origin are common names usually used in git, but they don't have to be.

While the question involves Git for Windows, this seems to be the top result even when searching for Visual Studio Tools For Git (extension in VS 2012, native support in VS 2013).

Using the solutions above as a guide I determined that Visual Studio Git Tools makes moving repos (or even entire directory structure for all repos) locally very easy.

1) Close Visual Studio. 2) Move the Repo folder(s) to new location. 3) Open Visual Studio. Open Team Explorer. Switch to "Connect" view (plug icon at top). 3a) If Repos still show old path, click Refresh to force an update. 4) Repos that were moved locally should no longer be showing in "Local Git Repositories". 5) Click Add (not new or clone) and select the repo folder to add.

In step 5 you really are just providing a search path and the search automatically includes all subfolders. If you have multiple repos organized under a single root (independent repos just having the same parent folder) then selecting the parent will include all repos found below that.

Example: E:\Repos\RepoA E:\Repos\RepoB E:\Repos\RepoC

In Visual Studio Team Explorer [Add] > "E:\Repos\" > [Add] will return all three to the Local Repositories.

$.getJSON is an asynchronous request, meaning the code will continue to run even though the request is not yet done. You should trigger the second request when the first one is done, one of the choices you seen already in ComFreek's answer.

Alternatively you could use jQuery's $.when/.then(), similar to this:

var input = "netuetamundis";  var sID;  $(document).ready(function () {     $.when($.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/" + input + "?api_key=API_KEY_HERE", function () {         obj = name;         sID = obj.id;         console.log(sID);     })).then(function () {         $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function (stats) {             console.log(stats);         });     }); }); 

This would be more open for future modification and separates out the responsibility for the first call to know about the second call.

The first call can simply complete and do it's own thing not having to be aware of any other logic you may want to add, leaving the coupling of the logic separated.

I prefer fork + execlp for "more fine-grade" control as doron mentioned. Example code shown below.

Store you command in a char array parameters, and malloc space for the result.

int fd[2];
pipe(fd);
if ( (childpid = fork() ) == -1){
   fprintf(stderr, "FORK failed");
   return 1;
} else if( childpid == 0) {
   close(1);
   dup2(fd[1], 1);
   close(fd[0]);
   execlp("/bin/sh","/bin/sh","-c",parameters,NULL);
}
wait(NULL);
read(fd[0], result, RESULT_SIZE);
printf("%s\n",result);

IF both POS_History_bim_data_*.zip and POS_History_bim_data_*.zip.trg exists in  Y:\ExternalData\RSIDest\ Folder then Delete File Y:\ExternalData\RSIDest\Target_slpos_unzip_done.dat

Probably simplest explanation the difference between apply and applymap:

apply takes the whole column as a parameter and then assign the result to this column

applymap takes the separate cell value as a parameter and assign the result back to this cell.

NB If apply returns the single value you will have this value instead of the column after assigning and eventually will have just a row instead of matrix.

Data transfer between two platform requires a common data format. JSON is a common global format to send cross platform data.

drawChart(600/50, JSON.parse('<?php echo json_encode($day); ?>'), JSON.parse('<?php echo json_encode($week); ?>'), JSON.parse('<?php echo json_encode($month); ?>'), JSON.parse('<?php echo json_encode(createDatesArray(cal_days_in_month(CAL_GREGORIAN, date('m',strtotime('-1 day')), date('Y',strtotime('-1 day'))))); ?>'))

This is the answer to your question. The answer may look very complex. You can see a simple example describing the communication between server side and client side here

$employee = array(
 "employee_id" => 10011,
   "Name" => "Nathan",
   "Skills" =>
    array(
           "analyzing",
           "documentation" =>
            array(
              "desktop",
                "mobile"
             )
        )
);

Conversion to JSON format is required to send the data back to client application ie, JavaScript. PHP has a built in function json_encode(), which can convert any data to JSON format. The output of the json_encode function will be a string like this.

{
    "employee_id": 10011,
    "Name": "Nathan",
    "Skills": {
        "0": "analyzing",
        "documentation": [
            "desktop",
            "mobile"
        ]
    }
}

On the client side, success function will get the JSON string. Javascript also have JSON parsing function JSON.parse() which can convert the string back to JSON object.

$.ajax({
        type: 'POST',
        headers: {
            "cache-control": "no-cache"
        },
        url: "employee.php",
        async: false,
        cache: false,
        data: {
            employee_id: 10011
        },
        success: function (jsonString) {
            var employeeData = JSON.parse(jsonString); // employeeData variable contains employee array.
    });

Use:

-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;

The use-case for CORS is simple. Imagine the site alice.com has some data that the site bob.com wants to access. This type of request traditionally wouldn’t be allowed under the browser’s same origin policy. However, by supporting CORS requests, alice.com can add a few special response headers that allows bob.com to access the data. In order to understand it well, please visit this nice tutorial.. How to solve the issue of CORS

EDIT: I see now by the comments that you are asking about the button text, and not the file path. My bad. I'll leave my original answer below in case someone else who stumbles upon this question interprets it the way I originally did.

2nd EDIT: I had deleted this answer because I decided that I misunderstood the question and my answer was not relevant. However, comments in another answer indicated that people still wanted to see this answer so I'm undeleting it.

MY ORIGINAL ANSWER (I thought the OP was asking about the path, not the button text):

This is not a supported feature for security reasons. The Opera web browser used to support this but it was removed. Think about what would be possible if this were supported; You could make a page with a file upload input, pre-populate it with a path to some sensitive file and then auto-submit the form using javascript triggered by the onload event. This would happen too fast for the user to do anything about it.

If your menu height is variable (for responsiveness or because it's loaded dynamically), you can set the top margin to where the fixed div ends. For example:

CSS

.fixed-header {
    width: 100%;
    margin: 0 auto;
    position: fixed;
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    -ms-box-sizing: border-box;
    box-sizing: border-box;
    z-index: 999;
}

Javascript

$(document).ready(function() {
    var contentPlacement = $('#header').position().top + $('#header').height();
    $('#content').css('margin-top',contentPlacement);
});

HTML

...
<div id="header" class="fixed-header"></div>
<div id="content">...</div>
...

Here's a fiddle (https://jsfiddle.net/632k9xkv/5/) that goes a little beyond this with both a fixed nav menu and header in an attempt to hopefully make this a useful sample.

At my last job we ran statistics once a week. If I remember correctly, we scheduled them on a Thursday night, and on Friday the DBAs were very careful to monitor the longest running queries for anything unexpected. (Friday was picked because it was often just after a code release, and tended to be a fairly low traffic day.) When they saw a bad query they would find a better query plan and save that one so it wouldn't change again unexpectedly. (Oracle has tools to do this for you automatically, you tell it the query to optimize and it does.)

Many organizations avoid running statistics out of fear of bad query plans popping up unexpectedly. But this usually means that their query plans get worse and worse over time. And when they do run statistics then they encounter a number of problems. The resulting scramble to fix those issues confirms their fears about the dangers of running statistics. But if they ran statistics regularly, used the monitoring tools as they are supposed to, and fixed issues as they came up then they would have fewer headaches, and they wouldn't encounter them all at once.

The most likely explanations for that error are:

1. The file you are attempting to load is not an executable file. CreateProcess requires you to provide an executable file. If you wish to be able to open any file with its associated application then you need ShellExecute rather than CreateProcess.
2. There is a problem loading one of the dependencies of the executable, i.e. the DLLs that are linked to the executable. The most common reason for that is a mismatch between a 32 bit executable and a 64 bit DLL, or vice versa. To investigate, use Dependency Walker's profile mode to check exactly what is going wrong.

Reading down to the bottom of the code, I can see that the problem is number 1.

This is the simplest way

np.random.uniform(start,stop,(rows,columns))

$(this).closest('div') is same as $(this).parents('div').eq(0).

CharField has max_length of 255 characters while TextField can hold more than 255 characters. Use TextField when you have a large string as input. It is good to know that when the max_length parameter is passed into a TextField it passes the length validation to the TextArea widget.

With ASP.NET Web Pages you can do this on a single page as a basic GET example (the simplest possible thing that can work.

var json = Json.Encode(new {
    orientation = Cache["orientation"],
    alerted = Cache["alerted"] as bool?,
    since = Cache["since"] as DateTime?
});
Response.Write(json);

$("a").each(function() {

Configure Fiddler as a 'reverse proxy' on Windows

(for Mac, see the link in Partizano's comment below)

I know there's already an answer suggesting this, however I want to provide the explanation and instructions for this that Telerik should have provided, and also cover some of the 'gotchas', so here goes:

What does it mean to configure Fiddler as a 'reverse proxy'?

• By default, Fiddler only monitors outgoing requests from the machine on which you're running Fiddler
• To monitor incoming requests, you need to configure Fiddler to work as a 'reverse proxy'
• What this means is that you need to set Fiddler up as a 'proxy' that will intercept incoming http requests that are sent to a specific port (8888) on the machine where you want to listen to the incoming requests. Fiddler will then forward those requests to the web server on the same machine by sending them to the usual port for http requests (usually port 80 or 443 for https). It's actually very quick and easy to do!
• The standard way to set this up with Fiddler is to get Fiddler to intercept all request sent to Port '8888' (since this won't normally be used by anything else, although you could just as easily use another port)
• You then need to use the registry editor to get Fiddler to forward any http requests that Fiddler receives on port 8888, so that they're forwarded to the standard http port (port 80, port 443 for an https request, or another custom port that your web server is set to listen on)

NOTE: For this to work, any request you want to intercept must be sent to port 8888

You do this by appending :8888 to your hostname, for example like this for an MVC route:

http://myhostname:8888/controller/action

Walkthrough

Ensure Fiddler can accept remote http requests on port 8888:

Run Fiddler as administrator Go to Tools > Fiddler Options > Connections, and ensure that 'Allow remote computers to connect' is checked, and 'Fiddler listens on port' is set to 8888:

Configure Fiddler to forward requests received on port 8888 to port 80

• Close Fiddler
• Start REGEDIT
• Create a new DWORD named ReverseProxyForPort inside HKEY_CURRENT_USER\SOFTWARE\Microsoft\Fiddler2.
  • Now set the DWORD value to the local port you'd like to re-route inbound traffic to (generally port 80 for a standard HTTP server)
• To do this, right-click the DWORD you created and select 'Modify'. Ensure 'Base' is set to 'Decimal' and enter '80' (or another port) as the 'Value data':

Ensure that port 8888 is opened on the firewall

• You must ensure that port 8888 is open to external requests (it won't be by default if your server is firewall-protected)

That's it! Fiddler should now be set up as a reverse proxy, to intercept all requests from port 8888 (so that you can view them in Fiddler), and it will then forward them to your web server to actually be handled.

Test a request

• Restart Fiddler
• To test that Fiddler is intercepting external requests, open a browser on the same machine where you've set up Fiddler as a reverse proxy. Navigate your browser to http://127.0.0.1:8888
• This tests making a basic request to to port 8888
• You should see the request intercepted by Fiddler
• Now you can test a request from another machine, for example by making a request from a browser on another machine like this (where 'remoteHostname' is a hostname on the machine where you've set up Fiddler as a reverse proxy) :

http://remoteHostname:8888/controller/action

• Alternatively, you can compose a request by using another instance of Fiddler on a remote machine, using a URL similar to the one above. This will allow you to make either a GET or a POST request.

IMPORTANT: Once you've finished viewing your request(s), go back to Tools > Fiddler Options > Connections and remove the 'Allow remote computers to connect' option, otherwise 3rd parties will be able to bounce traffic through your server

If you don't wan't to disable long click because you need to perform some functionality on long click than returning true is a better option to do so.

Your edittext long click will be like this.

edittext.setOnLongClickListener(new View.OnLongClickListener() {
      @Override
      public boolean onLongClick(View v) {
            //  Do Something or Don't
            return true;
      }
});

As per documentation Returning "True" will indicate that long click have been handled so no need to perform default operations.

I tested this on API level 16, 22 and 25. Its working fine for me. Hope this will help.

In the Visual Studio, if you define a property X in a class and you want to use this class only as a type, after building your project you will get a warning that says "Field X is never assigned to, and will always has its default value".

By adding a { get; set; } to X property, you will not get this warning.

In addition in Visual Studio 2013 and upper versions, by adding { get; set; } you are able to see all references to that property.

Multiply the number and then divide it by what you multiplied it by before.

For example,

perc = double.Parse("3.555)*1000;
result = perc/1000

For checking Safari I used this:

$.browser.safari = ($.browser.webkit && !(/chrome/.test(navigator.userAgent.toLowerCase())));
if ($.browser.safari) {
    alert('this is safari');
}

It works correctly.

It's not built in, but I've seen / used this code. This allows you to use this:

[mapView setCenterCoordinate:myCoord zoomLevel:13 animated:YES];

Note: This is not my code, I did not write it, so therefore can't take credit for it

Check if your activity layout overrides the theme, look for your activity layout located at layout/*your_activity*.xml and look for TextView that contains android:textColor="(some hex code") something like that on activity layout, and remove it. Then run your code again.

Here you go:

InputStream is = new ByteArrayInputStream( myString.getBytes() );

Update For multi-byte support use (thanks to Aaron Waibel's comment):

InputStream is = new ByteArrayInputStream(Charset.forName("UTF-16").encode(myString).array());

Please see ByteArrayInputStream manual.

It is safe to use a charset argument in String#getBytes(charset) method above.

After JDK 7+ you can use

java.nio.charset.StandardCharsets.UTF_16

instead of hardcoded encoding string:

InputStream is = new ByteArrayInputStream(StandardCharsets.UTF_16.encode(myString).array());

Instead of hitting "F5" Just hit:

"Ctrl + F5"

Try sending the UTF-8 Charset header:

<?php header ('Content-type: text/html; charset=utf-8'); ?>

And the HTML meta:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

If you just want the list, then you should ask here: http://unix.stackexchange.com

The answer is: cd / && find -name *.js

If you want to implement this, you have to specify the language.

Using a js file you can capture the following, that can be used in the codebehind as well:

<script type="text/javascript">
    alert('Server: ' + window.location.hostname);
    alert('Full path: ' + window.location.href);
    alert('Virtual path: ' + window.location.pathname);
    alert('HTTP path: ' + 
        window.location.href.replace(window.location.pathname, ''));    
</script>

I get a compile time error with Bob's (i.e. the questioner's) code. Stream.Length is a long whereas BinaryReader.ReadBytes takes an integer parameter. In my case, I do not expect to be dealing with Streams large enough to require long precision, so I use the following:

Stream s;
byte[] b;

if (s.Length > int.MaxValue) {
  throw new Exception("This stream is larger than the conversion algorithm can currently handle.");
}

using (var br = new BinaryReader(s)) {
  b = br.ReadBytes((int)s.Length);
}

A sorting algorithm is said to be stable if two objects with equal keys appear in the same order in sorted output as they appear in the input array to be sorted. Some sorting algorithms are stable by nature like Insertion sort, Merge Sort, Bubble Sort, etc. And some sorting algorithms are not, like Heap Sort, Quick Sort, etc.

Background: a "stable" sorting algorithm keeps the items with the same sorting key in order. Suppose we have a list of 5-letter words:

peach
straw
apple
spork

If we sort the list by just the first letter of each word then a stable-sort would produce:

apple
peach
straw
spork

In an unstable sort algorithm, straw or spork may be interchanged, but in a stable one, they stay in the same relative positions (that is, since straw appears before spork in the input, it also appears before spork in the output).

We could sort the list of words using this algorithm: stable sorting by column 5, then 4, then 3, then 2, then 1. In the end, it will be correctly sorted. Convince yourself of that. (by the way, that algorithm is called radix sort)

Now to answer your question, suppose we have a list of first and last names. We are asked to sort "by last name, then by first". We could first sort (stable or unstable) by the first name, then stable sort by the last name. After these sorts, the list is primarily sorted by the last name. However, where last names are the same, the first names are sorted.

You can't stack unstable sorts in the same fashion.

May I recommend you to Beautiful Soup. Soup is a very good lib to parse all of your html document.

soup = BeatifulSoup(html_doc)
titleName = soup.title.name

'some+multi+word+string'.replace(/\+/g, ' ');
                                   ^^^^^^

If you're using an IntelliJ editor, under

• Preferences/Settings
  • Javascript
    • Code Quality Tools
      • JSHint
        • Predefined (at bottom), click Set

You can type in anything, for instance console:false, and it will add that to the list (.jshintrc) as well - as a global.

1. First think you should create object $res = new \stdClass();

2. then assign object with key and value thay $res->success = false;

There are a js-free solution.

Set type=submit to the button you'd like to be default and type=button to other buttons. Now in the form below you can hit Enter in any input fields, and the Render button will work (despite the fact it is the second button in the form).

Example:

    <button id='close_renderer_button' class='btn btn-success'
            title='??????? ? ?????????????? ?????????'
            type=button>
      <span class='glyphicon glyphicon-edit'> </span> Edit program
    </button>
    <button id='render_button' class='btn btn-primary'
            title='????????? ???????'
            type=submit
            formaction='javascript:alert("Bingo!");'>
      <span class='glyphicon glyphicon-send'> </span> Render
    </button>

Tested in FF24 and Chrome 35 (formaction is html5 feature, but type is not).

In bootstrap you can use .text-centerto align center. also add .row and .col-md-* to your code.

align= is deprecated,

Added .col-xs-* for demo

UPDATE(OCT 2017)

For those who are reading this and want to use the new version of bootstrap (beta version), you can do the above in a simpler way, using Boostrap Flexbox utilities classes

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css" rel="stylesheet" />
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet" />
<div class="container footer">
  <div class="d-flex justify-content-between">
    <div class="p-1">
      <p>Hello there</p>
    </div>
    <div class="p-1">
      <a href="#" class="btn btn-warning" onclick="changeLook()">Re</a>
      <a href="#" class="btn btn-warning" onclick="changeBack()">Rs</a>
    </div>
    <div class="p-1">
      <a href="#"><i class="fa fa-facebook-square fa-2x"></i></a>
      <a href="#"><i class="fa fa-twitter fa-2x"></i></a>
      <a href="#"><i class="fa fa-google-plus fa-2x"></i></a>

The above answers require you to malloc a new stream object.

public <T>
boolean containsByLambda(Collection<? extends T> c, Predicate<? super T> p) {

    for (final T z : c) {
        if (p.test(z)) {
            return true;
        }
    }
    return false;
}

public boolean containsTabById(TabPane tabPane, String id) {
    return containsByLambda(tabPane.getTabs(), z -> z.getId().equals(id));
}
...
if (containsTabById(tabPane, idToCheck))) {
   ...
}

You can either

fig, ax = plt.subplots()  #create figure and axes
candlestick(ax, quotes, ...)

or

candlestick(plt.gca(), quotes) #get the axis when calling the function

The first gives you more flexibility. The second is much easier if candlestick is the only thing you want to plot

For linux/unix OS, you can use the shell syntax

const shell = require('child_process').execSync ; 

const currentPath= `/path/to/name.png`;
const newPath= `/path/to/another_name.png`;

shell(`mv ${currentPath} ${newPath}`);

That's it!

Table variables are just like int or varchar variables.

You don't need to drop them. They have the same scope rules as int or varchar variables

The scope of a variable is the range of Transact-SQL statements that can reference the variable. The scope of a variable lasts from the point it is declared until the end of the batch or stored procedure in which it is declared.

Also note the calendar.timegm() function as described by this blog entry:

import calendar
calendar.timegm(utc_timetuple)

The output should agree with the solution of vaab.

1. You don't need:

   @Configuration
   @ComponentScan("com.company.praktikant")
   

   @EnableWebSecurity already has @Configuration in it, and I cannot imagine why you put @ComponentScan there.

2. About CORS filter, I would just put this:

   @Bean
   public FilterRegistrationBean corsFilter() {
       UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
       CorsConfiguration config = new CorsConfiguration();
       config.setAllowCredentials(true);
       config.addAllowedOrigin("*");
       config.addAllowedHeader("*");
       config.addAllowedMethod("*");
       source.registerCorsConfiguration("/**", config);
       FilterRegistrationBean bean = new FilterRegistrationBean(new CorsFilter(source));
       bean.setOrder(0); 
       return bean;
   }
   

   Into SecurityConfiguration class and remove configure and configure global methods. You don't need to set allowde orgins, headers and methods twice. Especially if you put different properties in filter and spring security config :)

3. According to above, your "MyFilter" class is redundant.

4. You can also remove those:

   final AnnotationConfigApplicationContext annotationConfigApplicationContext = new AnnotationConfigApplicationContext();
   annotationConfigApplicationContext.register(CORSConfig.class);
   annotationConfigApplicationContext.refresh();
   

   From Application class.

5. At the end small advice - not connected to the question. You don't want to put verbs in URI. Instead of http://localhost:8080/getKunden you should use HTTP GET method on http://localhost:8080/kunden resource. You can learn about best practices for design RESTful api here: http://www.vinaysahni.com/best-practices-for-a-pragmatic-restful-api

You can use the familiar Matplotlib style calling a figure and subplot, but you simply need to specify the current axis using plt.gca(). An example:

plt.figure(1)
plt.subplot(2,2,1)
df.A.plot() #no need to specify for first axis
plt.subplot(2,2,2)
df.B.plot(ax=plt.gca())
plt.subplot(2,2,3)
df.C.plot(ax=plt.gca())

etc...

Please note that PrimeFaces supports the standard JSF 2.0+ keywords:

• @this Current component.
• @all Whole view.
• @form Closest ancestor form of current component.
• @none No component.

and the standard JSF 2.3+ keywords:

• @child(n) nth child.
• @composite Closest composite component ancestor.
• @id(id) Used to search components by their id ignoring the component tree structure and naming containers.
• @namingcontainer Closest ancestor naming container of current component.
• @parent Parent of the current component.
• @previous Previous sibling.
• @next Next sibling.
• @root UIViewRoot instance of the view, can be used to start searching from the root instead the current component.

But, it also comes with some PrimeFaces specific keywords:

• @row(n) nth row.
• @widgetVar(name) Component with given widgetVar.

And you can even use something called "PrimeFaces Selectors" which allows you to use jQuery Selector API. For example to process all inputs in a element with the CSS class myClass:

process="@(.myClass :input)"

See:

• https://primefaces.github.io/primefaces/10_0_0/#/core/searchexpression

     layout.setBackgroundDrawable(getResources().getDrawable(R.drawable.ready));

     layout.setBackground(getResources().getDrawable(R.drawable.ready));
else
     layout.setBackground(ContextCompat.getDrawable(this, R.drawable.ready));

It is an old question but i want to add that if you want to resize image according to viewport size only with css; you can use viewport units "vh (viewport height) or vw (viewport width)".

.img {
width: 100vw;
height: 100vh;
}

You aren't actually sending JSON. You are passing an object as the data, but you need to stringify the object and pass the string instead.

Your dataType: "json" only tells jQuery that you want it to parse the returned JSON, it does not mean that jQuery will automatically stringify your request data.

Change to:

$.ajax({
        type: "POST",
        url: hb_base_url + "consumer",
        contentType: "application/json",
        dataType: "json",
        data: JSON.stringify({
            first_name: $("#namec").val(),
            last_name: $("#surnamec").val(),
            email: $("#emailc").val(),
            mobile: $("#numberc").val(),
            password: $("#passwordc").val()
        }),
        success: function(response) {
            console.log(response);
        },
        error: function(response) {
            console.log(response);
        }
});

My 3 cents, though this is not a complete match to what the op wants. Here is the relevant reference.

namespace enums
{

template <typename T, T I, char ...Chars>
struct enums : std::integral_constant<T, I>
{
  static constexpr char const chars[sizeof...(Chars)]{Chars...};
};

template <typename T, T X, typename S, std::size_t ...I>
constexpr auto make(std::index_sequence<I...>) noexcept
{
  return enums<T, X, S().chars[I]...>();
}

#define ENUM(s, n) []() noexcept{\
  struct S { char const (&chars)[sizeof(s)]{s}; };\
  return enums::make<decltype(n), n, S>(\
    std::make_index_sequence<sizeof(s)>());}()

#define ENUM_T(s, n)\
  static constexpr auto s ## _tmp{ENUM(#s, n)};\
  using s ## _enum_t = decltype(s ## _tmp)

template <typename T, typename ...A, std::size_t N>
inline auto map(char const (&s)[N]) noexcept
{
  constexpr auto invalid(~T{});

  auto r{invalid};

  return
    (
      (
        invalid == r ?
          r = std::strncmp(A::chars, s, N) ? invalid : A{} :
          r
      ),
      ...
    );
}

}

int main()
{
  ENUM_T(echo, 0);
  ENUM_T(cat, 1);
  ENUM_T(ls, 2);

  std::cout << echo_enum_t{} << " " << echo_enum_t::chars << std::endl;

  std::cout << enums::map<int, echo_enum_t, cat_enum_t, ls_enum_t>("ls")) << std::endl;

  return 0;
}

So you generate a type, that you can convert to an integer and/or a string.

There's no standard for the layout of the LIST response. You'd have to write code to handle the most popular layouts. I'd start with Linux ls and Windows Server DIR formats. There's a lot of variety out there, though.

Fall back to the nlst method (returning the result of the NLST command) if you can't parse the longer list. For bonus points, cheat: perhaps the longest number in the line containing a known file name is its length.

I've found a one-liner solution on ETH Zurich Department of Physics wiki page (close to the end of that page). Just do a git gc to remove stale junk, and then

git rev-list --objects --all \
  | grep "$(git verify-pack -v .git/objects/pack/*.idx \
           | sort -k 3 -n \
           | tail -10 \
           | awk '{print$1}')"

will give you the 10 largest files in the repository.

There's also a lazier solution now available, GitExtensions now has a plugin that does this in UI (and handles history rewrites as well).

You should take care with readLines(...) and big files. Reading all lines at memory can be risky. Below is a example of how to read file and process just one line at time:

processFile = function(filepath) {
  con = file(filepath, "r")
  while ( TRUE ) {
    line = readLines(con, n = 1)
    if ( length(line) == 0 ) {
      break
    }
    print(line)
  }

  close(con)
}

Understand the risk of reading a line at memory too. Big files without line breaks can fill your memory too.

try

const MyFunctionnalComponent: React.FC = props => {_x000D_
  useEffect(() => {_x000D_
    // Using an IIFE_x000D_
    (async function anyNameFunction() {_x000D_
      await loadContent();_x000D_
    })();_x000D_
  }, []);_x000D_
  return <div></div>;_x000D_
};

You are doing it totally wrong, because you're depending on numbers, not characters and I am not sure if you want the random output to be just numbers, if so why the need to get all the alphabetic letters and all numbers and extract their length? Why not you just use rand(0, 62)?, even though you've forgot to initialize your variable $randstring before you declare the function.

Anyway, PHP offers you a very handy function for this purpose. It's str_shuffle(). Here is an example that suits your need.

<?php_x000D_
_x000D_
function randomString() {_x000D_
    $characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';_x000D_
    return str_shuffle($characters);_x000D_
}_x000D_
echo randomString();

Got this from Bing. Seems Microsoft has removed some features from the core framework and added it to a separate optional(?) framework component.

To quote from MSDN (http://msdn.microsoft.com/en-us/library/cc656912.aspx)

The .NET Framework 4 Client Profile does not include the following features. You must install the .NET Framework 4 to use these features in your application:

* ASP.NET
* Advanced Windows Communication Foundation (WCF) functionality
* .NET Framework Data Provider for Oracle
* MSBuild for compiling

In ExtJs, you can use

xtype: 'image'

to render a image.

Here is a fiddle showing rendering of binary data with extjs.

The simplest solution is to add this CSS to the children:

}

I've had this problem after installing the genymotion (another android amulator) plugin. A closer inspection reveled that gradle needs SDK tools version 19.1.0 in order to run (I had 19.0.3 previously).

To fix it, I had to edit build.gradle and under android I changed to: buildToolsVersion 19.1.0

Then I had to rebuild again, and the error was gone.

You could use a SUM (not COUNT!) combined with a CASE statement, like this:

SELECT SUM(CASE WHEN myColumn=1 THEN 1 ELSE 0 END)
FROM AD_CurrentView

Note: in my own test NULLs were not an issue, though this can be environment dependent. You could handle nulls such as:

SELECT SUM(CASE WHEN ISNULL(myColumn,0)=1 THEN 1 ELSE 0 END)
FROM AD_CurrentView

I had the same problem with slash in url get param, in my case following php code works:

$value = "hello/world"
$value = str_replace('/', '/', $value;?>
$value = urlencode($value);?>
# $value is now hello%26%2347%3Bworld

I first replace the slash by html entity and then I do the url encoding.

Another way,

SELECT ACCOUNT,

      MAX(CASE WHEN Period = '2001' THEN Value ELSE NULL END) [2001],

I believe that

nzd$date <- as.Date(nzd$date, format = "%d/%m/%Y")

is sufficient.

Don't use exit(0); That's bad practice at the best of times. Use Yii::$app->end();

So your code would look like

$this->redirect(['index'], 302);
Yii::$app->end();

That said though the actual problem was stopping POST requests, this is the wrong solution to that problem (although it does work). To stop POST requests you need to use access control.

public function behaviors()
{
    return [
        'access' => [
            'class' => \yii\filters\AccessControl::className(),
            'only' => ['create', 'update'],

React Native 0.62 Released - The Official solution is Flipper

Flipper is Android & iOS Mobile debugging tools without using debug mode in react native.

Since RN 0.62 (See this link), Flipper is initialized with default project.

Flipper has a few of plugins for debugging. The plugins include Layout, Network, Shared preferences

The greatest benefit of Flipper is not also many plugins but you can see Android / iOS device console debugging easily too.

The Flipper alert you about crash or network rejection too.

Layout plugin includes accessibility mode and target mode.

You can also see raw network request / response in your Application.

From the documentation:

The BuildAction property indicates what Visual Studio does with a file when a build is executed. BuildAction can have one of several values:

None - The file is not included in the project output group and is not compiled in the build process. An example is a text file that contains documentation, such as a Readme file.

Compile - The file is compiled into the build output. This setting is used for code files.

Content - The file is not compiled, but is included in the Content output group. For example, this setting is the default value for an .htm or other kind of Web file.

Embedded Resource - This file is embedded in the main project build output as a DLL or executable. It is typically used for resource files.
