I had the same problem and in my case the problem was missing and/or incorrect equals implementation on some types of fields in the entity object. At commit time, Hibernate checks ALL entities loaded in the session to check if they are dirty. If any of the entities are dirty, hibernate tries to persist them - no matter of the fact that the actual object that is requested a save operation is not related to the other entities.

Entity dirtiness is done by comparing every property of given object (with their equals methods) or UserType.equals if property has an associated org.Hibernate.UserType.

Another thing that surprised me was, in my transaction (using Spring annotation @Transactional), I was dealing with a single entity. Hibernate was complaining about some random entity that's unrelated to that entity being saved. What I realized is there is an outermost transaction we create at REST controller level, so the scope of the session is too big and hence all objects ever loaded as part of request processing get checked for dirtiness.

Hope this helps someone, some day.

Thanks Rags

In most cases, optimistic locking is more efficient and offers higher performance. When choosing between pessimistic and optimistic locking, consider the following:

• Pessimistic locking is useful if there are a lot of updates and relatively high chances of users trying to update data at the same time. For example, if each operation can update a large number of records at a time (the bank might add interest earnings to every account at the end of each month), and two applications are running such operations at the same time, they will have conflicts.

• Pessimistic locking is also more appropriate in applications that contain small tables that are frequently updated. In the case of these so-called hotspots, conflicts are so probable that optimistic locking wastes effort in rolling back conflicting transactions.

• Optimistic locking is useful if the possibility for conflicts is very low – there are many records but relatively few users, or very few updates and mostly read-type operations.

I was able to get my similar command working using the following approach:

msdeploy.exe -verb=sync "-source=dbFullSql=Server=THESERVER;Database=myDB;UID=sa;Pwd=saPwd" -dest=dbFullSql=c:\temp\test.sql

For your command (not that it helps much now), things would look something like this:

msdeploy.exe -verb=sync "-source=dbfullsql=Server=mysource;Trusted_Connection=false;UID=sa;Pwd=sapass!;Database=mydb;" "-dest=dbfullsql=Server=mydestsource;Trusted_Connection=false;UID=sa;Pwd=sapass!;Database=mydb;",computername=10.10.10.10,username=administrator,password=adminpass

The key points are:

• Use quotes around the source argument, and remove the embedded quotes around the connection string
• Use the alternative key names in building the SQL connection string that don't have spaces in them. For example, use "UID" instead of "User Id", "Server" instead of "Data Source", "Trusted_Connection" instead of "Integrated Security", and so forth. I was only able to get it to work once I removed all spaces from the connection string.

I didn't try adding the "computername" part at the end of the command line, but hopefully this info will help others reading this now get closer to their desired result.

Use a custom UINavigationController subclass, which implements the shouldPop method.

In Swift:

class NavigationController: UINavigationController, UINavigationBarDelegate
{
    var shouldPopHandler: (() -> Bool)?

    func navigationBar(_ navigationBar: UINavigationBar, shouldPop item: UINavigationItem) -> Bool
    {
        if let shouldPopHandler = self.shouldPopHandler, !shouldPopHandler()
        {
            return false
        }
        self.popViewController(animated: true) // Needed!
        return true
    }
}

When set, your shouldPopHandler() will be called to decide whether the controller will be pop or not. When not set it will just get popped as usual.

It is a good idea to disable UINavigationControllers interactivePopGestureRecognizer as the gesture won't call your handler otherwise.

As the other answers point out, once the resources are inside a jar file, things get really ugly. In our case, this solution:

https://stackoverflow.com/a/13227570/516188

works very well in the tests (since when the tests are run the code is not packed in a jar file), but doesn't work when the app actually runs normally. So what I've done is... I hardcode the list of the files in the app, but I have a test which reads the actual list from disk (can do it since that works in tests) and fails if the actual list doesn't match with the list the app returns.

That way I have simple code in my app (no tricks), and I'm sure I didn't forget to add a new entry in the list thanks to the test.

There are several tools which can import Excel to SQL Server.

I am using DbTransfer (http://www.dbtransfer.com/Products/DbTransfer) to do the job. It's primarily focused on transfering data between databases and excel, xml, etc...

I have tried the openrowset method and the SQL Server Import / Export Assitant before. But I found these methods to be unnecessary complicated and error prone in constrast to doing it with one of the available dedicated tools.

//You can use this ...

Step 1. The first step is to make sure that you declare support for the UITextViewDelegate protocol. This is done in your header file, as example here is the header called

EditorController.h:

@interface EditorController : UIViewController  {
  UITextView *messageTextView;
}

@property (nonatomic, retain) UITextView *messageTextView;

@end

Step 2. Next you will need to register the controller as the UITextView’s delegate. Continuing from the example above, here is how I have initialize the UITextView with EditorController as the delegate …

- (id) init {
    if (self = [super init]) {
        // define the area and location for the UITextView
        CGRect tfFrame = CGRectMake(10, 10, 300, 100);
        messageTextView = [[UITextView alloc] initWithFrame:tfFrame];
        // make sure that it is editable
        messageTextView.editable = YES;

        // add the controller as the delegate
        messageTextView.delegate = self;
    }

Step 3. And now the final piece of the puzzle is to take action in response to the shouldCahngeTextInRange message as follows:

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range 
  replacementText:(NSString *)text
{
    // Any new character added is passed in as the "text" parameter
    if ([text isEqualToString:@"\n"]) {
        // Be sure to test for equality using the "isEqualToString" message
        [textView resignFirstResponder];

        // Return FALSE so that the final '\n' character doesn't get added
        return FALSE;
    }
    // For any other character return TRUE so that the text gets added to the view
    return TRUE;
}

Unfortunately, for some reasons probably linked with HTTPS and certificates, the native .NET HttpListener requires admin privileges, and even for HTTP only protocol...

The good point

It is interesting to note that HTTP protocol is on top of TCP protocol, but launching a C# TCP listener doesn't require any admin privileges to run. In other words, it is conceptually possible to implement an HTTP server which do not requires admin privileges.

Alternative

Below, an example of project which doesn't require admin privileges: https://github.com/EmilianoElMariachi/ElMariachi.Http.Server

        var q = from b in listOfBoxes
                group b by b.Owner into g
                select new
                           {
                               Owner = g.Key,
                               Boxes = g.Count(),
                               TotalWeight = g.Sum(item => item.Weight),
                               TotalVolume = g.Sum(item => item.Volume)
                           };

I couldn't possibly explain it better than wikipedia does: http://en.wikipedia.org/wiki/MIME_type

In addition to e-mail applications, Web browsers also support various MIME types. This enables the browser to display or output files that are not in HTML format.

IOW, it helps the browser (or content consumer, because it may not just be a browser) determine what content they are about to consume; this means a browser may be able to make a decision on the correct plugin to use to display content, or a media player may be able to load up the correct codec or plugin.

The mail server on CentOS 6 and other IPv6 capable server platforms may be bound to IPv6 localhost (::1) instead of IPv4 localhost (127.0.0.1).

Typical symptoms:

[root@host /]# telnet 127.0.0.1 25
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused

[root@host /]# telnet localhost 25
Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 host ESMTP Exim 4.72 Wed, 14 Aug 2013 17:02:52 +0100

[root@host /]# netstat -plant | grep 25
tcp        0      0 :::25                       :::*                        LISTEN      1082/exim           

If this happens, make sure that you don't have two entries for localhost in /etc/hosts with different IP addresses, like this (bad) example:

[root@host /]# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost localhost4.localdomain4 localhost4
::1       localhost localhost.localdomain localhost6 localhost6.localdomain6

To avoid confusion, make sure you only have one entry for localhost, preferably an IPv4 address, like this:

[root@host /]# cat /etc/hosts
127.0.0.1 localhost  localhost.localdomain   localhost4.localdomain4 localhost4
::1       localhost6 localhost6.localdomain6

Saw this thread but I wanted to search for IDs that did not match my search. Code to do that:

found = $filter('filter')($scope.fish, {id: '!fish_id'}, false);

1)A primary key is a set of one or more attributes that uniquely identifies tuple within relation.

2)A foreign key is a set of attributes from a relation scheme which can be uniquely identify tuples fron another relation scheme.

One of the answers in this question might help you. There seems to be a platform agnostic version for python, but I haven't tried it yet.

Why not use an object¹?

var dict = { "a": 1, "b": 2, "c": 3 };

Then you can update it like so

dict.a = 23;

or

dict["a"] = 23;

If you wan't to delete² a particular key, it's as simple as:

delete dict.a;

_{¹ See Objects vs arrays in Javascript for key/value pairs.
² See the delete operator.}

First create a method :

public void hideNavigationBar() {
        final View decorView = this.getWindow().getDecorView();
        final int uiOptions =
                View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_STABLE;

        Timer timer = new Timer();
        TimerTask task = new TimerTask() {
            @Override
            public void run() {
                YourActivityName.this.runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        decorView.setSystemUiVisibility(uiOptions);

                    }
                });
            }
        };

        timer.scheduleAtFixedRate(task, 1, 2);

    }

Then you call it on onCreate() method of your activity. Call it again on the onResume() method. Then you may add another method in your activity like this:

@Override
    public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
        hideNavigationBar();
    }

That will be it. Do remember it will lock the screen till the next time user touches the screen, in Timer class you can change the delay and it will allow you change things for that instance.Then it will lock the screen again.

Method overriding is when a child class redefines the same method as a parent class, with the same parameters. For example, the standard Java class java.util.LinkedHashSet extends java.util.HashSet. The method add() is overridden in LinkedHashSet. If you have a variable that is of type HashSet, and you call its add() method, it will call the appropriate implementation of add(), based on whether it is a HashSet or a LinkedHashSet. This is called polymorphism.

Method overloading is defining several methods in the same class, that accept different numbers and types of parameters. In this case, the actual method called is decided at compile-time, based on the number and types of arguments. For instance, the method System.out.println() is overloaded, so that you can pass ints as well as Strings, and it will call a different version of the method.

First)

1. Goto menu: Project -> WindowsFormsApplication16 Properties/
2. write MyName in Assembly name and Default namespace textbox, then save.

Second)

1. open one old .cs file ( a class or a form)
2. right click on WindowsFormsApplication16 in front of namespace, goto Refactor -> Rename .
3. write MyName in New name textbox, in Rename Message Box.
4. press Ok, then Apply

When your activity is recreated after it was previously destroyed, you can recover your saved state from the Bundle that the system passes your activity. Both the onCreate() and onRestoreInstanceState() callback methods receive the same Bundle that contains the instance state information.

Because the onCreate() method is called whether the system is creating a new instance of your activity or recreating a previous one, you must check whether the state Bundle is null before you attempt to read it. If it is null, then the system is creating a new instance of the activity, instead of restoring a previous one that was destroyed.

static final String STATE_USER = "user";
private String mUser;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // Check whether we're recreating a previously destroyed instance
    if (savedInstanceState != null) {
        // Restore value of members from saved state
        mUser = savedInstanceState.getString(STATE_USER);
    } else {
        // Probably initialize members with default values for a new instance
        mUser = "NewUser";
    }
}

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
    savedInstanceState.putString(STATE_USER, mUser);
    // Always call the superclass so it can save the view hierarchy state
    super.onSaveInstanceState(savedInstanceState);
}

This should work for all IE8 minor versions

if ($.browser.msie  && parseInt($.browser.version, 10) === 8) {

Please note that $.browser is removed from jQuery 1.9

It is obvious but still it was hard to figure out for me,

Please check if your mobile device has enough space to install the apk. and it is not full.

>>> t = [1, 2, 3, 1, 2, 5, 6, 7, 8]
>>> t
[1, 2, 3, 1, 2, 5, 6, 7, 8]
>>> s = []
>>> for i in t:
       if i not in s:
          s.append(i)
>>> s
[1, 2, 3, 5, 6, 7, 8]

The minimum ranges you can rely on are:

• short int and int: -32,767 to 32,767
• unsigned short int and unsigned int: 0 to 65,535
• long int: -2,147,483,647 to 2,147,483,647
• unsigned long int: 0 to 4,294,967,295

This means that no, long int cannot be relied upon to store any 10 digit number. However, a larger type long long int was introduced to C in C99 and C++ in C++11 (this type is also often supported as an extension by compilers built for older standards that did not include it). The minimum range for this type, if your compiler supports it, is:

• long long int: -9,223,372,036,854,775,807 to 9,223,372,036,854,775,807
• unsigned long long int: 0 to 18,446,744,073,709,551,615

So that type will be big enough (again, if you have it available).

A note for those who believe I've made a mistake with these lower bounds - I haven't. The C requirements for the ranges are written to allow for ones' complement or sign-magnitude integer representations, where the lowest representable value and the highest representable value differ only in sign. It is also allowed to have a two's complement representation where the value with sign bit 1 and all value bits 0 is a trap representation rather than a legal value. In other words, int is not required to be able to represent the value -32,768.

input[type=text]
{
   height: 15px; 
   line-height: 15px;
}

this is correct way to set vertical-middle position.

The issue seems to be that you are adding the deffered.promise when deffered is itself the promise you should be adding:

Try changing to promises.push(deffered); so you don't add the unwrapped promise to the array.

 UploadService.uploadQuestion = function(questions){

            var promises = [];

            for(var i = 0 ; i < questions.length ; i++){

                var deffered  = $q.defer();
                var question  = questions[i]; 

                $http({

                    url   : 'upload/question',
                    method: 'POST',
                    data  : question
                }).
                success(function(data){
                    deffered.resolve(data);
                }).
                error(function(error){
                    deffered.reject();
                });

                promises.push(deffered);
            }

            return $q.all(promises);
        }

You need the :not() selector:

$('div[class^="first-"]:not(.first-bar)')

or, alternatively, the .not() method:

$('div[class^="first-"]').not('.first-bar');

server.address=10.20.20.10
server.port=8080
database.user=username
database.password=password
spring.datasource.url=jdbc:postgresql://${server.address}/${server.port}?user=${database.user}&password=${database.password}

To whoever is reading this, check out createMany() method.

/**
 * Create a Collection of new instances of the related model.
 *
 * @param  array  $records
 * @return \Illuminate\Database\Eloquent\Collection
 */
public function createMany(array $records)
{
    $instances = $this->related->newCollection();

    foreach ($records as $record) {
        $instances->push($this->create($record));
    }

    return $instances;

On MacOSX lldb needs to be code signed. The Debug and Release builds are set to code sign using a code signing certificate named lldb_codesign.

If you don't have one yet you will need to:
- Launch /Applications/Utilities/Keychain Access.app

- In Keychain Access select the "login" keychain in the "Keychains"
  list in the upper left hand corner of the window.

- Select the following menu item:

    Keychain Access->Certificate Assistant->Create a Certificate...

- Set the following settings

    Name = lldb_codesign
    Identity Type = Self Signed Root
    Certificate Type = Code Signing

- Click Continue
- Click Continue
- Click Done
- Click on the "My Certificates"
- Double click on your new lldb_codesign certificate
- Turn down the "Trust" disclosure triangle

    Change:
        When using this certificate: Always Trust

- Enter your login password to confirm and make it trusted

The next steps are necessary on SnowLeopard, but are probably because of a bug
how Keychain Access makes certificates.

- Option-drag the new lldb_codesign certificate from the login keychain to
  the System keychain in the Keychains pane of the main Keychain Access window
  to make a copy of this certificate in the System keychain.  You'll have to
  authorize a few more times, set it to be "Always trusted" when asked.
- Switch to the System keychain, and drag the copy of lldb_codesign you just
  made there onto the desktop.
- Switch to Terminal, and run the following:

sudo security add-trust -d -r trustRoot -p basic -p codeSign -k /Library/Keychains/System.keychain ~/Desktop/lldb_codesign.cer

- Right click on the "lldb_codesign" certificate in the "System" keychain (NOT
  "login", but the one in "System"), and select "Delete" to delete it from
  the "System" keychain.
- Reboot
- Clean and rebuild lldb and you should be able to debug.

That should do it.

[Note: - lldb is used in mac as gdb.]

Not yet, but there is the experimental :matches() pseudo-class function that does just that:

:matches(.a .b) .c {
  /* stuff goes here */
}

You can find more info on it here and here. Currently, most browsers support its initial version :any(), which works the same way, but will be replaced by :matches(). We just have to wait a little more before using this everywhere (I surely will).

bool IsDigitsOnly(string str)
{
    foreach (char c in str)
    {
        if (c < '0' || c > '9')
            return false;
    }

    return true;
}

Will probably be the fastest way to do it.

esp is as you say it is, the top of the stack.

ebp is usually set to esp at the start of the function. Function parameters and local variables are accessed by adding and subtracting, respectively, a constant offset from ebp. All x86 calling conventions define ebp as being preserved across function calls. ebp itself actually points to the previous frame's base pointer, which enables stack walking in a debugger and viewing other frames local variables to work.

Most function prologs look something like:

push ebp      ; Preserve current frame pointer
mov ebp, esp  ; Create new frame pointer pointing to current stack top
sub esp, 20   ; allocate 20 bytes worth of locals on stack.

Then later in the function you may have code like (presuming both local variables are 4 bytes)

mov [ebp-4], eax    ; Store eax in first local
mov ebx, [ebp - 8]  ; Load ebx from second local

FPO or frame pointer omission optimization which you can enable will actually eliminate this and use ebp as another register and access locals directly off of esp, but this makes debugging a bit more difficult since the debugger can no longer directly access the stack frames of earlier function calls.

EDIT:

For your updated question, the missing two entries in the stack are:

var_C = dword ptr -0Ch
var_8 = dword ptr -8
var_4 = dword ptr -4
*savedFramePointer = dword ptr 0*
*return address = dword ptr 4*
hInstance = dword ptr  8h
PrevInstance = dword ptr  0C
hlpCmdLine = dword ptr  10h
nShowCmd = dword ptr  14h

This is because the flow of the function call is:

• Push parameters (hInstance, etc.)
• Call function, which pushes return address
• Push ebp
• Allocate space for locals

You may not have permission to dba_sequences. So you can always just do:

select * from user_sequences;

    }
})

Taken from: http://www.w3.org/Style/Examples/007/units:

The em is simply the font size. In an element with a 2in font, 1em thus means 2in. Expressing sizes, such as margins and paddings, in em means they are related to the font size, and if the user has a big font (e.g., on a big screen) or a small font (e.g., on a handheld device), the sizes will be in proportion. Declarations such as 'text-indent: 1.5em' and 'margin: 1em' are extremely common in CSS.

em is basically CSS property for font sizes.

I'd suggest perl. (\d+.\d+.\d+.\d+) should probably do the trick.

EDIT: Just to make it more like a complete program, you could do something like the following (not tested):

#!/usr/bin/perl -w
use strict;

while (<>) {
    if (/(\d+\.\d+\.\d+\.\d+)/) {
        print "$1\n";
    }
}

This handles one IP per line. If you have more than one IPs per line, you need to use the /g option. man perlretut gives you a more detailed tutorial on regular expressions.

\tag also works in align*. Example:

\begin{align*}
  a(x)^{2} &= bx\tag{1}\\ 
  a(x)^{2} &= b\tag{2}\\ 
  ax &= b\tag{3}\\ 
  a(x)^{2}+bx &= c\tag{4}\\ 
  a(x)^{2}+c &= bx\tag{5}\\ 
  a(x)^{2} &= bx+c\tag{6}\\ \\ 
  Where\quad a, b, c \, \in N
\end{align*}

Output:

mhh. I got another solution which helped me, 'cause I just have two different sates:

• either the item is not clicked

And in my onCreate I call:

final ImageButton ib = (ImageButton) value.findViewById(R.id.imageButton);

    OnClickListener ocl =new OnClickListener() {
        @Override
        public void onClick(View button) {
            if (button.isSelected()){
                button.setSelected(false);
            } else {
                ib.setSelected(false);
                //put all the other buttons you might want to disable here...
                button.setSelected(true);
            }
        }
    };

ib.setOnClickListener(ocl);
//add ocl to all the other buttons

done. hope this helps. took me a while to figure out.

I believe using --no-index is what you're looking for:

git diff [<options>] --no-index [--] <path> <path>

as mentioned in the git manual:

This form is to compare the given two paths on the filesystem. You can omit the --no-index option when running the command in a working tree controlled by Git and at least one of the paths points outside the working tree, or when running the command outside a working tree controlled by Git.

Add this to your main CSS:

table td {
    border-top: none !important;
}

Use this for newer versions of bootstrap:

.table th, .table td { 
     border-top: none !important; 
 }

Try like this

#testdiv{
  border-left:1px solid;

}

Actually, as long as the parent element is positioned, you can set the child's height to 100%. Namely, in case you don't want the parent to be absolutely positioned. Let me explain further:

<style>
    #outer2 {
        padding-left: 23px;
        position: relative; 
        height:auto; 
        width:200px; 
        border: 1px solid red; 
    }
    #inner2 {
        left:0;
        position:absolute; 
        height:100%; 
        width:20px; 
        border: 1px solid black; 
    }
</style>

<div id='outer2'>
    <div id='inner2'>
    </div>
</div>

Although this post is old already, I'd like to add a much more simple solution and don't know why only such huge and/or complex solutions have been provided.

Here's a simple function to get what is needed:

function resizeInput() {
    const input = document.getElementById('myInput');
    input.style.width = `${input.scrollWidth}px`;
};

So, your goal is to search and replace?
According to the Official Visual Studio's keyboard shotcuts pdf, you can press Ctrl + H on Windows and Linux, or ??F on Mac to enable search and replace tool:

If you mean to disable the code, you just have to put <h1> in search, and replace to ####.

But if you want to use this regex instead, you may enable it in the icon: and use the regex: <h1>(.+?)<\/h1> and replace to: #### $1.

And as @tpartee suggested, here is some more information about Visual Studio's engine if you would like to learn more:

• Find and Replace Window (documentation)
• Quick Replace, Find and Replace Window (documentation)
• What flavor of Regex does Visual Studio Code use?

Check your servers error log, typically /var/log/apache2/error.log.

You should have access to the POST dictionary on the request object.

Use the glob function in a foreach loop to do whatever is an option. I also used the file_exists function in the example below to check if the directory exists before going any further.

$directory = 'my_directory/';
$extension = '.txt';

if ( file_exists($directory) ) {
   foreach ( glob($directory . '*' . $extension) as $file ) {
      echo $file;
   }
}
else {
   echo 'directory ' . $directory . ' doesn\'t exist!';
}

  if (e.KeyCode.ToString() == "Return")
  { 
      //do something
  }

The exception occurs due to this statement,

called_from.equalsIgnoreCase("add")

It seem that the previous statement

String called_from = getIntent().getStringExtra("called");

returned a null reference.

You can check whether the intent to start this activity contains such a key "called".

Rather than making a custom layout to get a small size and if you want to use Android's internal small size LAYOUT for the spinner, you should use:

"android.R.layout.simple_gallery_item" instead of "android.R.layout.simple_spinner_item".

ArrayAdapter<CharSequence> madaptor = ArrayAdapter
            .createFromResource(rootView.getContext(),
                                R.array.String_visitor,
                                android.R.layout.simple_gallery_item);

It can reduce the size of spinner's layout. It's just a simple trick.

If you want to reduce the size of a drop down list use this:

madaptor.setDropDownViewResource(android.R.layout.simple_gallery_item);

Not sure exactly what you try to denote with that syntax, but in almost all RDBMS-es you can use a subquery in the FROM clause (sometimes called an "inline-view"):

SELECT..
FROM (
     SELECT ...
     FROM ...
     ) my_select
WHERE ...

In advanced "enterprise" RDBMS-es (like oracle, SQL Server, postgresql) you can use common table expressions which allows you to refer to a query by name and reuse it even multiple times:

-- Define the CTE expression name and column list.
WITH Sales_CTE (SalesPersonID, SalesOrderID, SalesYear)
AS
-- Define the CTE query.
(
    SELECT SalesPersonID, SalesOrderID, YEAR(OrderDate) AS SalesYear
    FROM Sales.SalesOrderHeader
    WHERE SalesPersonID IS NOT NULL
)
-- Define the outer query referencing the CTE name.
SELECT SalesPersonID, COUNT(SalesOrderID) AS TotalSales, SalesYear
FROM Sales_CTE
GROUP BY SalesYear, SalesPersonID
ORDER BY SalesPersonID, SalesYear;

(example from http://msdn.microsoft.com/en-us/library/ms190766(v=sql.105).aspx)

Its usually better to whitelist characters you allow, rather than to blacklist characters you don't allow. both from a security standpoint, and from an ease of implementation standpoint.

If you do go down the blacklist route, here is an example, but be warned, the syntax is not simple.

http://groups.google.com/group/regex/browse_thread/thread/0795c1b958561a07

If you want to whitelist all the accent characters, perhaps using unicode ranges would help? Check out this link.

http://www.regular-expressions.info/unicode.html

Joins can only be used when there is an association between entities. Your Employee entity should not have a field named id_team, of type int, mapped to a column. It should have a ManyToOne association with the Team entity, mapped as a JoinColumn:

@ManyToOne
@JoinColumn(name="ID_TEAM")
private Team team;

Then, the following query will work flawlessly:

select e from Employee e inner join e.team

Which will load all the employees, except those that aren't associated to any team.

The same goes for all the other fields which are a foreign key to some other table mapped as an entity, of course (id_boss, id_profession).

It's time for you to read the Hibernate documentation, because you missed an extremely important part of what it is and how it works.

If the relation must not be bidirectional then an @ElementCollection might be easier than using a lazy One2Many collection.

The basic way to get the min/max value of an Array. If you need the unsorted array, you may create a copy or pass it to a method that returns the min or max. If not, sorted array is better since it performs faster in some cases.

public class MinMaxValueOfArray {
    public static void main(String[] args) {
        int[] A = {2, 4, 3, 5, 5};
        Arrays.sort(A);
        int min = A[0];
        int max = A[A.length -1];
        System.out.println("Min Value = " + min);        
        System.out.println("Max Value = " + max);
    }
}

This works for me:

@echo OFF

setlocal ENABLEEXTENSIONS
set KEY_NAME="HKEY_CURRENT_USER\Software\Microsoft\Command Processor"
set VALUE_NAME=DefaultColor

FOR /F "usebackq skip=4 tokens=1-3" %%A IN (`REG QUERY %KEY_NAME% /v %VALUE_NAME% 2^>nul`) DO (
    set ValueName=%%A
    set ValueType=%%B
    set ValueValue=%%C
)

if defined ValueName (
    @echo Value Name = %ValueName%
    @echo Value Type = %ValueType%
    @echo Value Value = %ValueValue%
) else (
    @echo %KEY_NAME%\%VALUE_NAME% not found.
)

usebackq is needed since the command to REG QUERY uses double quotes.

skip=4 ignores all the output except for the line that has the value name, type and value, if it exists.

2^>nul prevents the error text from appearing. ^ is the escape character that lets you put the > in the for command.

When I run the script above as given, I get this output:

Value Name = DefaultColor
Value Type = REG_DWORD
Value Value = 0x0

If I change the value of VALUE_NAME to BogusValue then I get this:

"HKEY_CURRENT_USER\Software\Microsoft\Command Processor"\BogusValue not found.

Annotation Approach

@ComponentScan({ "x.y.z", "x.y.z.dao" })

for php7 you can do that:

sudo apt-get install php-gd php-xml php7.0-mbstring

Since the original post was regarding the consequences of using the .bat or .cmd suffix, not necessarily the commands inside the file...

One other difference between .bat and .cmd is that if two files exist with the same file name and both those extensions, then:

• entering filename or filename.bat at the command line will run the .bat file

• to run the .cmd file, you have to enter filename.cmd

Note that RFC 6266 supersedes the RFCs referenced below. Section 7 outlines some of the related security concerns.

The authority on the content-disposition header is RFC 1806 and RFC 2183. People have also devised content-disposition hacking. It is important to note that the content-disposition header is not part of the HTTP 1.1 standard.

The HTTP 1.1 Standard (RFC 2616) also mentions the possible security side effects of content disposition:

15.5 Content-Disposition Issues

RFC 1806 [35], from which the often implemented Content-Disposition
(see section 19.5.1) header in HTTP is derived, has a number of very
serious security considerations. Content-Disposition is not part of
the HTTP standard, but since it is widely implemented, we are
documenting its use and risks for implementors. See RFC 2183 [49]
(which updates RFC 1806) for details.

Use minDate as string:

$('#datePickerId').datepicker({minDate: '0'});

This would set today as minimum selectable date .

Use Entry.insert. For example:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
e = Entry(root)
e.insert(END, 'default text')
e.pack()
root.mainloop()

Or use textvariable option:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
v = StringVar(root, value='default text')
e = Entry(root, textvariable=v)
e.pack()
root.mainloop()

//this is the code you have to use in you controller 

        $config['upload_path'] = './uploads/';  

// directory (http://localhost/codeigniter/index.php/your directory)

        $config['allowed_types'] = 'gif|jpg|png|jpeg';  
//Image type  

        $config['max_size'] = 0;    

 // I have chosen max size no limit 
        $new_name = time() . '-' . $_FILES["txt_file"]['name']; 

//Added time function in image name for no duplicate image 

        $config['file_name'] = $new_name;

//Stored the new name into $config['file_name']

        $this->load->library('upload', $config);

        if (!$this->upload->do_upload() && !empty($_FILES['txt_file']['name'])) {
            $error = array('error' => $this->upload->display_errors());
            $this->load->view('production/create_images', $error);
        } else {
            $upload_data = $this->upload->data();   
        }

I was getting the same error with jQuery formvaliadator, but when I removed a console.log inside success: function, it worked.

Using the data points from the accepted answer you can use polynomial interpolation to obtain a formula.

WolframAlpha Input: interpolating polynomial {{1,.63},{2,.82}, {3,1}, {4,1.13}, {5,1.5}, {6, 2}, {7,3}}

Formula: 0.00223611x^6 - 0.0530417x^5 + 0.496319x^4 - 2.30479x^3 + 5.51644x^2 - 6.16717x + 3.14

And use in Groovy code:

import java.math.*
def convert = {x -> (0.00223611*x**6 - 0.053042*x**5 + 0.49632*x**4 - 2.30479*x**3 + 5.5164*x**2 - 6.167*x + 3.14).setScale(2, RoundingMode.HALF_UP) }
(1..7).each { i -> println(convert(i)) }

Yes, you can do this. The knack you need is the concept that there are two ways of getting tables out of the table server. One way is ..

FROM TABLE A

The other way is

FROM (SELECT col as name1, col2 as name2 FROM ...) B

Notice that the select clause and the parentheses around it are a table, a virtual table.

So, using your second code example (I am guessing at the columns you are hoping to retrieve here):

SELECT a.attr, b.id, b.trans, b.lang
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, a.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)

Notice that your real table attribute is the first table in this join, and that this virtual table I've called b is the second table.

This technique comes in especially handy when the virtual table is a summary table of some kind. e.g.

SELECT a.attr, b.id, b.trans, b.lang, c.langcount
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, at.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)
JOIN (
 SELECT count(*) AS langcount,  at.attribute
 FROM attributeTranslation at
 GROUP BY at.attribute
) c ON (a.id = c.attribute)

See how that goes? You've generated a virtual table c containing two columns, joined it to the other two, used one of the columns for the ON clause, and returned the other as a column in your result set.

style="padding-top: 8px"

Use this to shift your div up or down in your row. Works wonders for me.

Yes, Java SE is where to start. All the tasks you mention can be handled with it.

Java ME is the Mobile Edition, and EE is Enterprise Edition; these are specialized / extended versions of Standard Edition.

You can pass small bits of key/value pair data via the query string:

res.redirect('/?error=denied');

And javascript on the home page can access that and adjust its behavior accordingly.

Note that if you don't mind /category staying as the URL in the browser address bar, you can just render directly instead of redirecting. IMHO many times people use redirects because older web frameworks made directly responding difficult, but it's easy in express:

app.post('/category', function(req, res) {

  // Process the data received in req.body

  res.render('home.jade', {error: 'denied'});
});

As @Dropped.on.Caprica commented, using AJAX eliminates the URL changing concern.

In terms of entities (or objects) you have a Class object which has a collection of Students and a Student object that has a collection of Classes. Since your StudentClass table only contains the Ids and no extra information, EF does not generate an entity for the joining table. That is the correct behaviour and that's what you expect.

Now, when doing inserts or updates, try to think in terms of objects. E.g. if you want to insert a class with two students, create the Class object, the Student objects, add the students to the class Students collection add the Class object to the context and call SaveChanges:

using (var context = new YourContext())
{
    var mathClass = new Class { Name = "Math" };
    mathClass.Students.Add(new Student { Name = "Alice" });
    mathClass.Students.Add(new Student { Name = "Bob" });

    context.AddToClasses(mathClass);
    context.SaveChanges();
}

This will create an entry in the Class table, two entries in the Student table and two entries in the StudentClass table linking them together.

You basically do the same for updates. Just fetch the data, modify the graph by adding and removing objects from collections, call SaveChanges. Check this similar question for details.

Edit:

According to your comment, you need to insert a new Class and add two existing Students to it:

using (var context = new YourContext())
{
    var mathClass= new Class { Name = "Math" };
    Student student1 = context.Students.FirstOrDefault(s => s.Name == "Alice");
    Student student2 = context.Students.FirstOrDefault(s => s.Name == "Bob");
    mathClass.Students.Add(student1);
    mathClass.Students.Add(student2);

    context.AddToClasses(mathClass);
    context.SaveChanges();
}

Since both students are already in the database, they won't be inserted, but since they are now in the Students collection of the Class, two entries will be inserted into the StudentClass table.

For phpmydamin you can use following step

1. Go to python install path like

    cd C:\Users\Enamul\AppData\Local\Programs\Python\Python37-32\Scripts
   

2. Run the command pip install PyMySQL

3. In the python shell import library like import pymysql

4. connection to databasbe

    db = pymysql.connect(host='localhost',user='root',passwd='yourpassword', database="bd")
   

5. get cursor cursor = db.cursor()

6. Create table like

   cursor.execute("CREATE TABLE customers (name VARCHAR(255), address VARCHAR(255))")
   

You can also use the interface builder to create these effects easily for simple situations. Since the z-values of the views will depend on the order they are listed in the Document Outline, you can drag a UIVisualEffectView onto the document outline before the view you want to blur. This automatically creates a nested UIView, which is the contentView property of the given UIVisualEffectView. Nest things within this view that you want to appear on top of the blur.

You can also easily take advantage of the vibrancy UIVisualEffect, which will automatically create another nested UIVisualEffectView in the document outline with vibrancy enabled by default. You can then add a label or text view to the nested UIView (again, the contentView property of the UIVisualEffectView), to achieve the same effect that the "> slide to unlock" UI element.

For Decryption:

     def decrypt(my_key=KEY, my_iv=IV, encryptText=encrypttext):

        key = binascii.unhexlify(my_key)
        iv = binascii.unhexlify(my_iv)
        encryptor = AES.new(key, AES.MODE_CBC, iv, segment_size=128)  # Initialize encryptor
        result = encryptor.decrypt(binascii.a2b_hex(encryptText))
        padder = PKCS7Padder()
        decryptText=padder.decode(result)  

           return {
          "plain": encryptText,
          "key": binascii.hexlify(key),
          "iv": binascii.hexlify(iv),
          "decryptedTest": decryptText
}

There sure is (in gnuplot 4.4+):

plot for [i=1:1000] 'data'.i.'.txt' using 1:2 title 'Flow '.i

The variable i can be interpreted as a variable or a string, so you could do something like

plot for [i=1:1000] 'data'.i.'.txt' using 1:($2+i) title 'Flow '.i

if you want to have lines offset from each other.

Type help iteration at the gnuplot command line for more info.

Also be sure to see @DarioP's answer about the do for syntax; that gives you something closer to a traditional for loop.

The suggested causes are now proven to be mostly impossible. I'm running SSMS V17.9.2 against SS 2014 and still have the problem. Memory problems have existed with this tool since at least 2006 when I started using SSMS.

Yes, MS 'wants' to get rid of diagramming but users won't let them. I have a feeling they will never fix any of these issues because they want users to be so fed up with the tool that enough of them quit using it and they can abandon it entirely.

Restarting is still a workaround if you can stand doing so numerous times per day.

iOS 14

For me, view.window is null on iOS 14.

extension UIViewController {
    var topBarHeight: CGFloat {
        var top = self.navigationController?.navigationBar.frame.height ?? 0.0
        if #available(iOS 13.0, *) {
            top += UIApplication.shared.windows.first?.windowScene?.statusBarManager?.statusBarFrame.height ?? 0
        } else {
            top += UIApplication.shared.statusBarFrame.height
        }
        return top
    }
}

Another way to achieve this:

const [Name, setName] = useState({val:"", callback: null});_x000D_
React.useEffect(()=>{_x000D_
  console.log(Name)_x000D_
  const {callback} = Name;_x000D_
  callback && callback();_x000D_
}, [Name]);_x000D_
setName({val:'foo', callback: ()=>setName({val: 'then bar'})})

There are at least these two issues I have observed for this problem: 1) It could be either because your sender username or password might not be correct 2) Or it could be as answered by Avinash above, the security condition on the account. Once you try SendMail using SMTP, you normally get a notification in to your account that it may be an unauthorized attempt to access your account, if not user can follow the link to turn the settings to lessSecureApp. Once this is done and smtp SendMail is tried again, it works.

public class SortingArray {

An alternative approach is to use numpy.resize() as in:

In [37]: shp = (50,100,25)
In [38]: arr = np.random.random_sample(shp)
In [45]: resized_arr = np.resize(arr, (np.prod(shp[:2]), shp[-1]))
In [46]: resized_arr.shape
Out[46]: (5000, 25)

# sanity check with other solutions
In [47]: resized = np.reshape(arr, (-1, shp[-1]))
In [48]: np.allclose(resized_arr, resized)
Out[48]: True

UPDATE: The latest version of Compare-Net-Objects is located on GitHub , has NuGet package and Tutorial. It can be called like

//This is the comparison class
CompareLogic compareLogic = new CompareLogic();

ComparisonResult result = compareLogic.Compare(person1, person2);

//These will be different, write out the differences
if (!result.AreEqual)
    Console.WriteLine(result.DifferencesString);

Or if you need to change some configuration, use

CompareLogic basicComparison = new CompareLogic() 
{ Config = new ComparisonConfig()
   { MaxDifferences = propertyCount 
     //add other configurations
   }
};

Full list of configurable parameters is in ComparisonConfig.cs

Original answer:

The limitations I see in your code:

• The biggest one is that it doesn't do a deep object comparison.

• It doesn't do an element by element comparison in case properties are lists or contain lists as elements (this can go n-levels).

• It doesn't take into account that some type of properties should not be compared (e.g. a Func property used for filtering purposes, like the one in the PagedCollectionView class).

• It doesn't keep track of what properties actually were different (so you can show in your assertions).

I was looking today for some solution for unit-testing purposes to do property by property deep comparison and I ended up using: http://comparenetobjects.codeplex.com.

It is a free library with just one class which you can simply use like this:

var compareObjects = new CompareObjects()
{
    CompareChildren = true, //this turns deep compare one, otherwise it's shallow
    CompareFields = false,
    CompareReadOnly = true,
    ComparePrivateFields = false,
    ComparePrivateProperties = false,
    CompareProperties = true,
    MaxDifferences = 1,
    ElementsToIgnore = new List<string>() { "Filter" }
};

Assert.IsTrue(
    compareObjects.Compare(objectA, objectB), 
    compareObjects.DifferencesString
);

Also, it can be easily re-compiled for Silverlight. Just copy the one class into a Silverlight project and remove one or two lines of code for comparisons that are not available in Silverlight, like private members comparison.

First, JavaScript's switch is no faster than if/else (and sometimes much slower).

Second, the only way to use switch with multiple variables is to combine them into one primitive (string, number, etc) value:

var stateA = "foo";
var stateB = "bar";
switch (stateA + "-" + stateB) {
    case "foo-bar": ...
    ...
}

But, personally, I would rather see a set of if/else statements.

Edit: When all the values are integers, it appears that switch can out-perform if/else in Chrome. See the comments.

This is similar to Solution 1 from @JSuar...

Assume your original city data is a named range called dataCity. In a new sheet, enter the following:

    A                 | B
  ----------------------------------------------------------
1 | =UNIQUE(dataCity) | Count
2 |                   | =DCOUNTA(dataCity,"City",{"City";$A2})
3 |                   | [copy down the formula above]
4 |                   | ...
5 |                   | ...

Depending on your project, you might want to consider using EditorConfig (https://editorconfig.org/). There's a Notepad++ plugin which will load an .editorconfig where you can specify "lf" as the mandatory line ending.

I've only started using it, but it's nice so far, and open source projects I've worked on have included .editorconfig files for years. The "EOL Conversion" setting isn't changed, so it can be a bit confusing, but if you "View > Show Symbol > Show End of Line", you can see that it's adding LF instead of CRLF, even when "EOL Conversion" and the lower bottom corner shows something else (e.g. Windows (CR LF)).

If you are looking to create an instant messenger for Android, this code should get you started somewhere.

Excerpt from the source :

This is a simple IM application runs on Android, application makes http request to a server, implemented in php and mysql, to authenticate, to register and to get the other friends' status and data, then it communicates with other applications in other devices by socket interface.

EDIT : Just found this! Maybe it's not related to WhatsApp. But you can use the source to understand how chat applications are programmed.

There is a website called Scringo. These awesome people provide their own SDK which you can integrate in your existing application to exploit cool features like radaring, chatting, feedback, etc. So if you are looking to integrate chat in application, you could just use their SDK. And did I say the best part? It's free!

*UPDATE : * Scringo services will be closed down on 15 February, 2015.

When an iFrame loads, it initially contains the #document, so checking the load state might best work by checking what's there now..

if ($('iframe').contents().find('body').children().length > 0) {
    // is loaded
} else {
    // is not loaded
}

This worked for me:

Go to

Control Panel\System and Security\System

select

Advanced system settings from the left panel
from Advanced tab click on Environment Variables

In the System variables section search for (create if doesn't exist)

PYTHONPATH

and set

C:\Python27\;C:\Python27\Scripts;

or your desired version

You need to restart CMD.

In case it still doesn't work you might want to leave in the PATH variable only your desired version.

This all depends on what sort of access you have to your SAP system. An ABAP program that exports the data and/or an RFC that your macro can call to directly get the data or have SAP create the file is probably best.

However as a general rule people looking for this sort of answer are looking for an immediate solution that does not require their IT department to spend months customizing their SAP system.

In that case you probably want to use SAP GUI Scripting. SAP GUI scripting allows you to automate the Windows SAP GUI in much the same way as you automate Excel. In fact you can call the SAP GUI directly from an Excel macro. Read up more on it here. The SAP GUI has a macro recording tool much like Excel does. It records macros in VBScript which is nearly identical to Excel VBA and can usually be copied and pasted into an Excel macro directly.

Example Code

Here is a simple example based on a SAP system I have access to.

Public Sub SimpleSAPExport()
  Set SapGuiAuto  = GetObject("SAPGUI") 'Get the SAP GUI Scripting object
  Set SAPApp = SapGuiAuto.GetScriptingEngine 'Get the currently running SAP GUI 
  Set SAPCon = SAPApp.Children(0) 'Get the first system that is currently connected
  Set session = SAPCon.Children(0) 'Get the first session (window) on that connection

  'Start the transaction to view a table
  session.StartTransaction "SE16"

  'Select table T001
  session.findById("wnd[0]/usr/ctxtDATABROWSE-TABLENAME").Text = "T001"
  session.findById("wnd[0]/tbar[1]/btn[7]").Press

  'Set our selection criteria
  session.findById("wnd[0]/usr/txtMAX_SEL").text = "2"
  session.findById("wnd[0]/tbar[1]/btn[8]").press

  'Click the export to file button
  session.findById("wnd[0]/tbar[1]/btn[45]").press

  'Choose the export format
  session.findById("wnd[1]/usr/subSUBSCREEN_STEPLOOP:SAPLSPO5:0150/sub:SAPLSPO5:0150/radSPOPLI-SELFLAG[1,0]").select
  session.findById("wnd[1]/tbar[0]/btn[0]").press

  'Choose the export filename
  session.findById("wnd[1]/usr/ctxtDY_FILENAME").text = "test.txt"
  session.findById("wnd[1]/usr/ctxtDY_PATH").text = "C:\Temp\"

  'Export the file
  session.findById("wnd[1]/tbar[0]/btn[0]").press
End Sub

Script Recording

To help find the names of elements such aswnd[1]/tbar[0]/btn[0] you can use script recording. Click the customize local layout button, it probably looks a bit like this:
Then find the Script Recording and Playback menu item.

Within that the More button allows you to see/change the file that the VB Script is recorded to. The output format is a bit messy, it records things like selecting text, clicking inside a text field, etc.

Edit: Early and Late binding

The provided script should work if copied directly into a VBA macro. It uses late binding, the line Set SapGuiAuto = GetObject("SAPGUI") defines the SapGuiAuto object.

If however you want to use early binding so that your VBA editor might show the properties and methods of the objects you are using, you need to add a reference to sapfewse.ocx in the SAP GUI installation folder.

Plugin DebugKit for cake will do the job as well. https://github.com/cakephp/debug_kit

None of the other answers worked for me. For me the device registered with eclipse after I rebooted the phone. Process for that is going to vary by phone model.

The striping/replacement/scaping of single quotes from user input (input sanitation), has to be done before the SQL statement reaches the database.

with many functions in matlab, you don't need to iterate at all.

for example, to multiply by it's position in the list:

m = [1:numel(list)]';
elm = list.*m;

vectorized algorithms in matlab are in general much faster.

In addition to the answers above, you can check the type of object using type(plt.subplots()) which returns a tuple, on the other hand, type(plt.subplot()) returns matplotlib.axes._subplots.AxesSubplot which you can't unpack.

I had a different variation on this question where I only had a single DATETIME field and needed a limit after a group by or distinct after sorting descending based on the datetime field, but this is what helped me:

select distinct (column) from
(select column from database.table
order by date_column DESC) as hist limit 10

In this instance with the split fields, if you can sort on a concat, then you might be able to get away with something like:

select name,date,time from
(select name from table order by concat(date,' ',time) ASC)
as sorted

Then if you wanted to limit you would simply add your limit statement to the end:

select name,date,time from
(select name from table order by concat(date,' ',time) ASC)
as sorted limit 10

Here is my preferred quickest and easiest solution. Works well if all slides have the same background color that you want to remove.

Step 1. In Powerpoint, "Save As" (shortcut F12) PNG, "All Slides".

Now you have a folder full of these PNG images of all your slides. The problem is that they still have a background. So now:

Step 2. Batch remove background color of all the PNG images, for example by following the steps in this SE answer.

From See Java Static Variable Methods:

• It is a variable which belongs to the class and not to object(instance)
• Static variables are initialized only once , at the start of the execution. These variables will be initialized first, before the initialization of any instance variables
• A single copy to be shared by all instances of the class
• A static variable can be accessed directly by the class name and doesn’t need any object.

Instance and class (static) variables are automatically initialized to standard default values if you fail to purposely initialize them. Although local variables are not automatically initialized, you cannot compile a program that fails to either initialize a local variable or assign a value to that local variable before it is used.

What the compiler actually does is to internally produce a single class initialization routine that combines all the static variable initializers and all of the static initializer blocks of code, in the order that they appear in the class declaration. This single initialization procedure is run automatically, one time only, when the class is first loaded.

In case of inner classes, they can not have static fields

An inner class is a nested class that is not explicitly or implicitly declared static.

...

Inner classes may not declare static initializers (§8.7) or member interfaces...

Inner classes may not declare static members, unless they are constant variables...

See JLS 8.1.3 Inner Classes and Enclosing Instances

final fields in Java can be initialized separately from their declaration place this is however can not be applicable to static final fields. See the example below.

final class Demo
{
    private final int x;
    private static final int z;  //must be initialized here.

    static 
    {
        z = 10;  //It can be initialized here.
    }

    public Demo(int x)
    {
        this.x=x;  //This is possible.
        //z=15; compiler-error - can not assign a value to a final variable z
    }
}

This is because there is just one copy of the static variables associated with the type, rather than one associated with each instance of the type as with instance variables and if we try to initialize z of type static final within the constructor, it will attempt to reinitialize the static final type field z because the constructor is run on each instantiation of the class that must not occur to static final fields.

I would like to add that this problem is similar to common Java memory leaks.

When the JVM garbage collector is unable to clear the "waste" memory of your Java / Java EE application over time, OutOfMemoryError: Java heap space will be the outcome.

It is important to perform a proper diagnostic first:

• Enable verbose:gc. This will allow you to understand the memory growing pattern over time.
• Generate and analyze a JVM Heap Dump. This will allow you to understand your application memory footprint and pinpoint the source of the memory leak(s).
• You can also use Java profilers and runtime memory leak analyzer such as Plumbr as well to help you with this task.

I ran into the same issue and found another way to do this. It worked for in my case as it was a relatively small application.

First, the user will a click button in the component which needs to be printed. This will set a flag that can be accessed by the app component. Like so

.html file

<button mat-button (click)="printMode()">Print Preview</button>

.ts file

  printMode() {
    this.utilities.printMode = true;
  }

In the html of the app component, we hide everything except the router-outlet. Something like below

<div class="container">       
  <app-header *ngIf="!utilities.printMode"></app-header>
  <mat-sidenav-container>
    <mat-sidenav *ngIf="=!utilities.printMode">
      <app-sidebar></app-sidebar>
    </mat-sidenav>
    <mat-sidenav-content>
      <router-outlet></router-outlet>
    </mat-sidenav-content>
  </mat-sidenav-container>
</div>

With similar ngIf conidtions, we can also adjust the html template of the component to only show or hide things in printMode. So that the user will see only what needs to get printed when print preview is clicked.

We can now simply print or go back to normal mode with the below code

.html file

<button mat-button class="doNotPrint" (click)="print()">Print</button>
<button mat-button class="doNotPrint" (click)="endPrint()">Close</button>

.ts file

  print() {
    window.print();
  }

  endPrint() {
    this.utilities.printMode = false;
  } 

.css file (so that the print and close button's don't get printed)

@media print{
   .doNotPrint{display:none !important;}
 }

I am using JsonProperty attributes when serializing but ignoring them when deserializing using this ContractResolver:

public class IgnoreJsonPropertyContractResolver: DefaultContractResolver
    {
        protected override IList<JsonProperty> CreateProperties(Type type, MemberSerialization memberSerialization)
        {
            var properties = base.CreateProperties(type, memberSerialization);
            foreach (var p in properties) { p.PropertyName = p.UnderlyingName; }
            return properties;
        }
    }

The ContractResolver just sets every property back to the class property name (simplified from Shimmy's solution). Usage:

var airplane= JsonConvert.DeserializeObject<Airplane>(json, 
    new JsonSerializerSettings { ContractResolver = new IgnoreJsonPropertyContractResolver() });

trim() is your choice, but if you want to use replace method -- which might be more flexiable, you can try the following:

String stripppedString = myString.replaceAll("(^ )|( $)", "");

Please try this in your linear layout

android:layout_centerHorizontal="true"
android:layout_centerVertical="true"

You can do in this in Angular with ECMAScript6 by using the spread operator:

let copy = {...myObject};

If you know, that your results implements a certain interface you could use the interface as datatype:

public void LogEmployees<T>(IEnumerable<T> list)
{
    foreach (T item in list)
    {

    }
}

Your problem is this

<button type="button" value=" Send" class="btn btn-success" type="submit" id="submit" />

You've set the type twice. Your browser is only accepting the first, which is "button".

<button type="submit" value=" Send" class="btn btn-success" id="submit" />

your fadeIn() function calls the fadeOut() function, which calls the fadeIn() function again. the recursion is in the JS.

Sometimes, all that's required is to stop the dev server before installing/updating packages.

Although this issue is quite old, i think this is relevant news / the most recent answer: Microsoft open-sourced XAML Behaviours and posted a blog post how to update to this version: https://devblogs.microsoft.com/dotnet/open-sourcing-xaml-behaviors-for-wpf/

To save you a click, this is the main steps to migrate:

1. Remove reference to “Microsoft.Expression.Interactions” and “System.Windows.Interactivity”
2. Install the Microsoft.Xaml.Behaviors.Wpf NuGet package.
3. XAML files – replace the xmlns namespaces http://schemas.microsoft.com/expression/2010/interactivity and http://schemas.microsoft.com/expression/2010/interactions with http://schemas.microsoft.com/xaml/behaviors
4. C# files – replace the usings in c# files “Microsoft.Xaml.Interactivity” and “Microsoft.Xaml.Interactions” with “Microsoft.Xaml.Behaviors”

handle = open(path.rstrip("/") + "/" + filename.lstrip("/"), 'wb')
ftp.retrbinary('RETR %s' % filename, handle.write)

Numpy arrays have an astype method. Just do y.astype(int).

Note that it might not even be necessary to do this, depending on what you're using the array for. Bool will be autopromoted to int in many cases, so you can add it to int arrays without having to explicitly convert it:

>>> x
array([ True, False,  True], dtype=bool)
>>> x + [1, 2, 3]
array([2, 2, 4])

set style="height:300px !important;" and "imgBanner" for img tag.

<img src="/image/1.jpg" class="imgBanner" style="width:100%; height:300px !important;">

then if you want responsive image, so you can use jquery as:

$.(function(){
   $(window).resize(respWhenResize);
   respWhenResize();
 })



respWhenResize(){
 
       if (pagesize < 578) {
         $('.imgBanner').css('height','200px')
        } else if (pagesize > 578 ) {
            $('.imgBanner').css('height','300px')
        }
     }

you also use preg_replace_callback function . and this function is identical to its sibling preg_replace except for it can take a callback function which gives you more control on how you manipulate your output.

$str = "this is a   string";

echo preg_replace_callback(
        '/\s+/',
        function ($matches) {
            return "";
        },
        $str
      );

In addition to @senderle's here, some might also be wondering how to use the functionality of multiprocessing.Pool.

The nice thing is that there is a .Pool() method to the manager instance that mimics all the familiar API of the top-level multiprocessing.

from itertools import repeat
import multiprocessing as mp
import os
import pprint

def f(d: dict) -> None:
    pid = os.getpid()
    d[pid] = "Hi, I was written by process %d" % pid

if __name__ == '__main__':
    with mp.Manager() as manager:
        d = manager.dict()
        with manager.Pool() as pool:
            pool.map(f, repeat(d, 10))
        # `d` is a DictProxy object that can be converted to dict
        pprint.pprint(dict(d))

Output:

$ python3 mul.py 
{22562: 'Hi, I was written by process 22562',
 22563: 'Hi, I was written by process 22563',
 22564: 'Hi, I was written by process 22564',
 22565: 'Hi, I was written by process 22565',
 22566: 'Hi, I was written by process 22566',
 22567: 'Hi, I was written by process 22567',
 22568: 'Hi, I was written by process 22568',
 22569: 'Hi, I was written by process 22569',
 22570: 'Hi, I was written by process 22570',
 22571: 'Hi, I was written by process 22571'}

This is a slightly different example where each process just logs its process ID to the global DictProxy object d.

This is in case you need both classes present. For either or logic just use ||

$('el').hasClass('first-class') || $('el').hasClass('second-class')

Feel free to optimize as needed

None of these worked for me. My Bootstrap setup navigates to separate pages (so I can't do it on a click action, but the active class is removed on the navigation to a new page), and my urls don't match exactly. So here's what I did, based on my exception-based situation. Hope it helps others:

//Adding the active class to Twitter bootstrap navs, with a few alternate approaches

$(document).ready(function() {
  var rawhref = window.location.href; //raw current url 
  var newpage = ((window.location.href.match(/([^\/]*)\/?$/)[1]).substring(1)); //take only the last part of the url, and chop off the first char (substring), since the contains method below is case-sensitive. Don't need to do this if they match exactly.
  if (newpage == 'someNonMatchingURL') {  //deal with an exception literally
    newpage = 'matchingNavbarText'
    }
  if (rawhref.indexOf('somePartofURL') != -1) { //look for a consistent part of the path in the raw url to deal with variable urls, etc.
    newpage = "moreMatchingNavbarText"
    }
  $(".nav li a:contains('" + newpage + "')").parent().addClass('active'); //add the active class. Note that the contains method requires the goofy quote syntax to insert a variable.

});

I tried using a CLR function and it was more than twice as fast as BCP. Here's my code.

Original Method:

SET @bcpCommand = 'bcp "SELECT blobcolumn FROM blobtable WHERE ID = ' + CAST(@FileID AS VARCHAR(20)) + '" queryout "' + @FileName + '" -T -c'
EXEC master..xp_cmdshell @bcpCommand

CLR Method:

declare @file varbinary(max) = (select blobcolumn from blobtable WHERE ID = @fileid)
declare @filepath nvarchar(4000) = N'c:\temp\' + @FileName
SELECT Master.dbo.WriteToFile(@file, @filepath, 0)

C# Code for the CLR function

using System;
using System.Data;
using System.Data.SqlTypes;
using System.IO;
using Microsoft.SqlServer.Server;

namespace BlobExport
{
    public class Functions
    {
      [SqlFunction]
      public static SqlString WriteToFile(SqlBytes binary, SqlString path, SqlBoolean append)
      {        
        try
        {
          if (!binary.IsNull && !path.IsNull && !append.IsNull)
          {         
            var dir = Path.GetDirectoryName(path.Value);           
            if (!Directory.Exists(dir))              
              Directory.CreateDirectory(dir);            
              using (var fs = new FileStream(path.Value, append ? FileMode.Append : FileMode.OpenOrCreate))
            {
                byte[] byteArr = binary.Value;
                for (int i = 0; i < byteArr.Length; i++)
                {
                    fs.WriteByte(byteArr[i]);
                };
            }
            return "SUCCESS";
          }
          else
             "NULL INPUT";
        }
        catch (Exception ex)
        {          
          return ex.Message;
        }
      }
    }
}

And for all input and select:

$("input[required], select[required]").attr("oninvalid", "this.setCustomValidity('Required!')");
$("input[required], select[required]").attr("oninput", "setCustomValidity('')");

If you don't know the row number, but do know some values then you can use subset

x <- structure(list(A = c(5,    3.5, 3.25, 4.25,  1.5 ), 
                    B = c(4.25, 4,   4,    4.5,   4.5 ),
                    C = c(4.5,  2.5, 4,    2.25,  3   )
               ),
               .Names    = c("A", "B", "C"),
               class     = "data.frame",
               row.names = c(NA, -5L)
     )

subset(x, A ==5 & B==4.25 & C==4.5)

Use a CASE statement and do it like this:

SELECT 
    T1.Id [Id]
    ,CASE WHEN T2.Id IS NOT NULL THEN 'TRUE' ELSE 'FALSE' END [Has Foreign Key in T2]
FROM
    TABLE1 [T1]
    LEFT OUTER JOIN
        TABLE2 [T2]
        ON
        T2.Id = T1.Id

Here in simpler words:

DOM

• Tree model parser (Object based) (Tree of nodes).

• DOM loads the file into the memory and then parse- the file.

• Has memory constraints since it loads the whole XML file before parsing.

• DOM is read and write (can insert or delete nodes).

• If the XML content is small, then prefer DOM parser.

• Backward and forward search is possible for searching the tags and evaluation of the information inside the tags. So this gives the ease of navigation.

• Slower at run time.

SAX

• Event based parser (Sequence of events).

• SAX parses the file as it reads it, i.e. parses node by node.

• No memory constraints as it does not store the XML content in the memory.

• SAX is read only i.e. can’t insert or delete the node.

• Use SAX parser when memory content is large.

• SAX reads the XML file from top to bottom and backward navigation is not possible.

• Faster at run time.

Constant variables cannot be changed. Static variable are private to the file and only accessible within the program code and not to anyone else.

I think that it's not supported. If you have a look at this DefaultValueAccessor directive (see https://github.com/angular/angular/blob/master/modules/angular2/src/common/forms/directives/default_value_accessor.ts#L23). You will see that the value used to update the bound element is $event.target.value.

This doesn't apply in the case of inputs with type file since the file object can be reached $event.srcElement.files instead.

For more details, you can have a look at this plunkr: https://plnkr.co/edit/ozZqbxIorjQW15BrDFrg?p=info:

The answer to your problem is easy: replace the current Fragment with the new Fragment and push transaction onto the backstack. This preserves back button behaviour...

Creating a new Activity really defeats the whole purpose to use fragments anyway...very counter productive.

@Override
public void onClick(View v) {
    // Create new fragment and transaction
    Fragment newFragment = new chartsFragment(); 
    // consider using Java coding conventions (upper first char class names!!!)
    FragmentTransaction transaction = getFragmentManager().beginTransaction();

    // Replace whatever is in the fragment_container view with this fragment,
    // and add the transaction to the back stack
    transaction.replace(R.id.fragment_container, newFragment);
    transaction.addToBackStack(null);

    // Commit the transaction
    transaction.commit(); 
}

Workaround:

template<class T, size_t N>
struct simple_array { // like std::array in C++0x
   T arr[N];
};


class C : private simple_array<int, 3> 
{
      static simple_array<int, 3> myarr() {
           simple_array<int, 3> arr = {1,2,3};
           return arr;
      }
public:
      C() : simple_array<int, 3>(myarr()) {}
};

I assume that the text "username1" is just a placeholder for what will eventually be an actual username. Assuming that,

• If the username is not allowed to have spaces, then just search for everything before the first space or comma (thus finding both "u1 likes this" and "u1, u2, and u3 like this").
• If it is allowed to have a space, it would probably be easier to wrap each username in it's own span tag server-side, before sending it to the client, and then just working with the span tags.

GRANT USAGE ON SCHEMA schema_name TO user;

• If your SDK location path in Eclipse is in C:\Program Files (x86)\ change to C:\PROGRA~2\.
• If you are running 32-bit Windows, C:\Program Files\, change the path to C:\PROGRA~1\.

I think that what you're after is DESCRIBE

DESCRIBE table;

You can also use SHOW TABLES

SHOW TABLES;

to get a list of the tables in your database.

tl;dr script to update all installed packages

If you only want to upgrade one package, refer to @borgr's answer. I often find it necessary, or at least pleasing, to upgrade all my packages at once. Currently, pip doesn't natively support that action, but with sh scripting it is simple enough. You use pip list, awk (or cut and tail), and command substitution. My normal one-liner is:

for i in $(pip list -o | awk 'NR > 2 {print $1}'); do sudo pip install -U $i; done

This will ask for the root password. If you do not have access to that, the --user option of pip or virtualenv may be something to look into.

Try this definitely work.

SELECT p.PersonID AS person_id,
   p.Name, p.SS, 
   f.FearID AS fear_id,
   f.Fear 
   FROM person_fear AS pf 
      LEFT JOIN persons AS p ON pf.PersonID = p.PersonID 
      LEFT JOIN fears AS f ON pf.PersonID = f.FearID 
   WHERE f.FearID = pf.FearID AND p.PersonID = pf.PersonID

the whole if should be enclosed in brackets and the or operator is || an not !!, so

if ((Type == 2 && PageCount == 0) || (Type == 2 && PageCount == '')) { ...

I prefer Consolas.

"Inflating" a view means taking the layout XML and parsing it to create the view and viewgroup objects from the elements and their attributes specified within, and then adding the hierarchy of those views and viewgroups to the parent ViewGroup. When you call setContentView(), it attaches the views it creates from reading the XML to the activity. You can also use LayoutInflater to add views to another ViewGroup, which can be a useful tool in a lot of circumstances.

As we read in this answer, HTML5 will solve this for you if you're open to that route. HTML5 audio is supported in all modern browsers.

Here's a copy of the example:

var snd = new Audio("file.wav"); // buffers automatically when created
snd.play();

You can check instance of Traversable with a simple function. This would work for all this of Iterator because Iterator extends Traversable

function canLoop($mixed) {
    return is_array($mixed) || $mixed instanceof Traversable ? true : false;
}

• 401 (Unauthorized) response header -> Request authentication header

• Here are several WWW-Authenticate response headers. (The full list is at IANA: HTTP Authentication Schemes.)

  • WWW-Authenticate: Basic-> Authorization: Basic + token - Use for basic authentication
  • WWW-Authenticate: NTLM-> Authorization: NTLM + token (2 challenges)
  • WWW-Authenticate: Negotiate -> Authorization: Negotiate + token - used for Kerberos authentication
    • By the way: IANA has this angry remark about Negotiate: This authentication scheme violates both HTTP semantics (being connection-oriented) and syntax (use of syntax incompatible with the WWW-Authenticate and Authorization header field syntax).

You can set the Authorization: Basic header only when you also have the WWW-Authenticate: Basic header on your 401 challenge.

But since you have WWW-Authenticate: Negotiate this should be the case for Kerberos based authentication.

Here's a more robust procedure for altering the next value returned by a sequence, plus a whole lot more.

• First off it protects against SQL injection attacks since none of the strings passed in are used to directly create any of the dynamic SQL statements,
• Second it prevents the next sequence value from being set outside the bounds of the min or max sequence values. The next_value will be != min_value and between min_value and max_value.
• Third it takes the current (or proposed) increment_by setting as well as all the other sequence settings into account when cleaning up.
• Fourth all parameters except the first are optional and unless specified take on the current sequence setting as defaults. If no optional parameters are specified no action is taken.
• Finally if you try altering a sequence that doesn't exist (or is not owned by the current user) it will raise an ORA-01403: no data found error.

Here's the code:

If anyone is interested, here are some one-liners (and a note on loss of type information in CSV):

require 'csv'

rows = [[1,2,3],[4,5]]                    # [[1, 2, 3], [4, 5]]

# To CSV string
csv = rows.map(&:to_csv).join             # "1,2,3\n4,5\n"

# ... and back, as String[][]
rows2 = csv.split("\n").map(&:parse_csv)  # [["1", "2", "3"], ["4", "5"]]

# File I/O:
filename = '/tmp/vsc.csv'

# Save to file -- answer to your question
IO.write(filename, rows.map(&:to_csv).join)

# Read from file
# rows3 = IO.read(filename).split("\n").map(&:parse_csv)
rows3 = CSV.read(filename)

rows3 == rows2   # true
rows3 == rows    # false

Note: CSV loses all type information, you can use JSON to preserve basic type information, or go to verbose (but more easily human-editable) YAML to preserve all type information -- for example, if you need date type, which would become strings in CSV & JSON.

Though I would give an update using the new composition api.

Component

<template>
  <div @mouseenter="hovering = true" @mouseleave="hovering = false">
    {{ hovering }}
  </div>
</template>

<script>
  import { ref } from '@vue/compsosition-api'

  export default {
    setup() {
      const hovering = ref(false)
      return { hovering }
    }
  })
</script>

Reusable Composition Function

Creating a useHover function will allow you to reuse in any components.

export function useHover(target: Ref<HTMLElement | null>) {
  const hovering = ref(false)

  const enterHandler = () => (hovering.value = true)
  const leaveHandler = () => (hovering.value = false)

  onMounted(() => {
    if (!target.value) return
    target.value.addEventListener('mouseenter', enterHandler)
    target.value.addEventListener('mouseleave', leaveHandler)
  })

  onUnmounted(() => {
    if (!target.value) return
    target.value.removeEventListener('mouseenter', enterHandler)
    target.value.removeEventListener('mouseleave', leaveHandler)
  })

  return hovering
}

Here's a quick example calling the function inside a Vue component.

<template>
  <div ref="hoverRef">
    {{ hovering }}
  </div>
</template>

<script lang="ts">
  import { ref } from '@vue/compsosition-api'
  import { useHover } from './useHover'

  export default {
    setup() {
      const hoverRef = ref(null)
      const hovering = useHover(hoverRef)
      return { hovering, hoverRef }
    }
  })
</script>

You can also use a library such as @vuehooks/core which comes with many useful functions including useHover.

How about a simple Bash alias that you stick in your .bash_profile ?

You can remove the white space padding by setting bbox_inches="tight" in savefig:

plt.savefig("test.png",bbox_inches='tight')

You'll have to put the argument to bbox_inches as a string, perhaps this is why it didn't work earlier for you.

For Ruby programmers here is how you can assert. Have to include Minitest to get the asserts

    assert(@driver.find_element(:tag_name => "body").text.include?("Name"))

Just remove the .val(). Like:

if ( $('html').attr('lang') == 'fr-FR' ) {
    // do this
} else {
    // do that
}

I would do something like this

<div class="container">
  <div class="text">
    <p>text yay!</p>
  </div>
</div>

CSS:

.container {
    position: relative;
}

.container::before {
    position: absolute;
    top: 0;
    left: 0;
    bottom: 0;
    right: 0;
    background: url('/path/to/image.png');
    opacity: .4;
    content: "";
    z-index: -1;
}

It should work. This is assuming you are required to have a semi-transparent image BTW, and not a color (which you should just use rgba for). Also assumed is that you can't just alter the opacity of the image beforehand in Photoshop.

If you store the padding in resource files, you can simply call

int padding = getResources().getDimensionPixelOffset(R.dimen.padding);

It does the conversion for you.

Floating point numbers are represented in scientific notation as a number of only seven significant digits multiplied by a larger number that represents the place of the decimal place. More information about it on Wikipedia:

I also had trouble overruling a dependency in a third party library. I used scot's approach with the exclusion but I also added the dependency with the newer version in the pom. (I used Maven 3.3.3)

So for the stAX example it would look like this:

<dependency>
  <groupId>a.group</groupId>
  <artifactId>a.artifact</artifactId>
  <version>a.version</version>
  <exclusions>
    <!--  STAX comes with Java 1.6 -->
    <exclusion>
      <artifactId>stax-api</artifactId>
      <groupId>javax.xml.stream</groupId>
    </exclusion>
    <exclusion>
      <artifactId>stax-api</artifactId>
      <groupId>stax</groupId>
    </exclusion>
  </exclusions>

For some reasons, Webkit-based browsers don't follow the spec for the dialog box. An almost cross-working example would be close from the below example.

window.addEventListener("beforeunload", function (e) {
  var confirmationMessage = "\o/";

  (e || window.event).returnValue = confirmationMessage; //Gecko + IE
  return confirmationMessage;                            //Webkit, Safari, Chrome
});

There is already a string handling function Series.str.startswith(). You should try foo[foo.b.str.startswith('f')].

Result:

    a   b
1   2   foo
2   3   fat

I think what you expect.

Alternatively you can use contains with regex option. For example:

foo[foo.b.str.contains('oo', regex= True, na=False)]

Result:

    a   b
1   2   foo

na=False is to prevent Errors in case there is nan, null etc. values

Normally, that is not an error per se; it is a warning that the first file it found that matches the -lPI-Http argument to the compiler/linker is not valid. The error occurs when no other library can be found with the right content.

So, you need to look to see whether /dvlpmnt/libPI-Http.a is a library of 32-bit object files or of 64-bit object files - it will likely be 64-bit if you are compiling with the -m32 option. Then you need to establish whether there is an alternative libPI-Http.a or libPI-Http.so file somewhere else that is 32-bit. If so, ensure that the directory that contains it is listed in a -L/some/where argument to the linker. If not, then you will need to obtain or build a 32-bit version of the library from somewhere.

To establish what is in that library, you may need to do:

mkdir junk
cd junk
ar x /dvlpmnt/libPI-Http.a
file *.o
cd ..
rm -fr junk

The 'file' step tells you what type of object files are in the archive. The rest just makes sure you don't make a mess that can't be easily cleaned up.

Yes, Java (similar to other mainstream languages) uses lazy evaluation short-circuiting which means it evaluates as little as possible.

This means that the following code is completely safe:

if(p != null && p.getAge() > 10)

Also, a || b never evaluates b if a evaluates to true.

String[] namesArray = {"Sam","Pamela", "Dave", "Pascal", "Erik"};
String completeString
         =  IntStream.range(0,namesArray.length)
           .mapToObj(i -> namesArray[i]) // Converting each array element into Object
           .map(String::valueOf) // Converting object to String again
           .collect(Collectors.joining(",")); // getting a Concat String of all values
        System.out.println(completeString);

OUTPUT : Sam,Pamela,Dave,Pascal,Erik

String[] namesArray = {"Sam","Pamela", "Dave", "Pascal", "Erik"};

IntStream.range(0,namesArray.length)
               .mapToObj(i -> namesArray[i]) // Converting each array element into Object
               .map(String::valueOf) // Converting object to String again
               .forEach(s -> {
                //You can do various operation on each element here
                System.out.println(s);
               }); // getting a Concat String of all 

To Collect in the List:

String[] namesArray = {"Sam","Pamela", "Dave", "Pascal", "Erik"};
 List<String> namesList
                =  IntStream.range(0,namesArray.length)
                .mapToObj(i -> namesArray[i]) // Converting each array element into Object
                .map(String::valueOf) // Converting object to String again
                .collect(Collectors.toList()); // collecting elements in List
        System.out.println(listWithIndex);

No, there's no jQuery (or CSS) selector that does that.

You can readily use filter:

$("p").filter(function() {
    return $(this).text() === "hello";
}).css("font-weight", "bold");

It's not a selector, but it does the job. :-)

If you want to handle whitespace before or after the "hello", you might throw a $.trim in there:

return $.trim($(this).text()) === "hello";

For the premature optimizers out there, if you don't care that it doesn't match <p><span>hello</span></p> and similar, you can avoid the calls to $ and text by using innerHTML directly:

return this.innerHTML === "hello";

...but you'd have to have a lot of paragraphs for it to matter, so many that you'd probably have other issues first. :-)

As per James Newton King: If you create the serializer yourself rather than using JavaScriptConvert there is a NullValueHandling property which you can set to ignore.

Here's a sample:

JsonSerializer _jsonWriter = new JsonSerializer {
                                 NullValueHandling = NullValueHandling.Ignore
                             };

Alternatively, as suggested by @amit

JsonConvert.SerializeObject(myObject, 
                            Newtonsoft.Json.Formatting.None, 
                            new JsonSerializerSettings { 
                                NullValueHandling = NullValueHandling.Ignore
                            });

I was getting same error because of configuration issue in intellij. As shown in screenshot. Main and test module was pointing to two different JDK. (Press F12 on the intellij project to open module settings)

Also all my dto's were using @lombok.Builder which I changed it to @Data.

I needed all that, but I also needed python devel installed:

sudo yum install python-devel

openecry.com is a broker with plenty of information on an API and instructions on how to do yours. There are also other brokers with the OEC platform and all the bells and whistles a pro could ask for.

script/runner and rake tasks are perfectly fine to run as cron jobs.

Here's one very important thing you must remember when running cron jobs. They probably won't be called from the root directory of your app. This means all your requires for files (as opposed to libraries) should be done with the explicit path: e.g. File.dirname(__FILE__) + "/other_file". This also means you have to know how to explicitly call them from another directory :-)

Check if your code supports being run from another directory with

# from ~
/path/to/ruby /path/to/app/script/runner -e development "MyClass.class_method"
/path/to/ruby /path/to/rake -f /path/to/app/Rakefile rake:task RAILS_ENV=development

Also, cron jobs probably don't run as you, so don't depend on any shortcut you put in .bashrc. But that's just a standard cron tip ;-)

This function works to arrays and objects. obs: it works like array_column php function. It means that an optional third parameter can be passed to define what column will correspond to the indices of return.

function array_column(list, column, indice){
    var result;

    if(typeof indice != "undefined"){
        result = {};

        for(key in list)
            result[list[key][indice]] = list[key][column];
    }else{
        result = [];

        for(key in list)
            result.push( list[key][column] );
    }

    return result;
}

This is a conditional version:

function array_column_conditional(list, column, indice){
    var result;

    if(typeof indice != "undefined"){
        result = {};

        for(key in list)
            if(typeof list[key][column] !== 'undefined' && typeof list[key][indice] !== 'undefined')
                result[list[key][indice]] = list[key][column];
    }else{
        result = [];

        for(key in list)
            if(typeof list[key][column] !== 'undefined')
                result.push( list[key][column] );
    }

    return result;
}

usability:

var lista = [
  [1, 2, 3],
  [4, 5, 6],
  [7, 8, 9]
];

var obj_list = [
  {a: 1, b: 2, c: 3},
  {a: 4, b: 5, c: 6},
  {a: 8, c: 9}
];

var objeto = {
  d: {a: 1, b: 3},
  e: {a: 4, b: 5, c: 6},
  f: {a: 7, b: 8, c: 9}
};

var list_obj = {
  d: [1, 2, 3],
  e: [4, 5],
  f: [7, 8, 9]
};

console.log( "column list: ", array_column(lista, 1) );
console.log( "column obj_list: ", array_column(obj_list, 'b', 'c') );
console.log( "column objeto: ", array_column(objeto, 'c') );
console.log( "column list_obj: ", array_column(list_obj, 0, 0) );

console.log( "column list conditional: ", array_column_conditional(lista, 1) );
console.log( "column obj_list conditional: ", array_column_conditional(obj_list, 'b', 'c') );
console.log( "column objeto conditional: ", array_column_conditional(objeto, 'c') );
console.log( "column list_obj conditional: ", array_column_conditional(list_obj, 0, 0) );

Output:

/*
column list:  Array [ 2, 5, 8 ]
column obj_list:  Object { 3: 2, 6: 5, 9: undefined }
column objeto:  Array [ undefined, 6, 9 ]
column list_obj:  Object { 1: 1, 4: 4, 7: 7 }

column list conditional:  Array [ 2, 5, 8 ]
column obj_list conditional:  Object { 3: 2, 6: 5 }
column objeto conditional:  Array [ 6, 9 ]
column list_obj conditional:  Object { 1: 1, 4: 4, 7: 7 }

First you most get record count from

 Declare @TableRowsCount Int
 select @TableRowsCount= COUNT(*) from <Your_Table>

And then :

In SQL Server 2012

SELECT *
FROM  <Your_Table> As L
ORDER BY L.<your Field>
OFFSET <@TableRowsCount-@N> ROWS
FETCH NEXT @N ROWS ONLY;

In SQL Server 2008

SELECT *
FROM 
(
SELECT ROW_NUMBER() OVER(ORDER BY ID) AS sequencenumber, *
FROM  <Your_Table>
    Order By <your Field>
) AS TempTable
WHERE sequencenumber > @TableRowsCount-@N 

How about using Request — Simplified HTTP client.

Edit February 2020: Request has been deprecated so you probably shouldn't use it any more.

Here's a GET:

var request = require('request');
request('http://www.google.com', function (error, response, body) {
    if (!error && response.statusCode == 200) {
        console.log(body) // Print the google web page.
     }
})

OP also wanted a POST:

request.post('http://service.com/upload', {form:{key:'value'}})

From the function's definition (http://www.w3schools.com/jsref/jsref_replace.asp):

The replace() method searches a string for a specified value, or a regular expression, and returns a new string where the specified values are replaced.

This method does not change the original string.

Hence, the line: tt.replace(/,/g, '.') does not change the value of tt; it just returns the new value.

You need to replace this line with: tt = tt.replace(/,/g, '.')

Whoa. You're really over-complicating it by a very long distance. Try:

>>> print hex(0x12ef ^ 0xabcd)
0xb922

You seem to be ignoring these handy facts, at least:

• Python has native support for hexadecimal integer literals, with the 0x prefix.
• "Hexadecimal" is just a presentation detail; the arithmetic is done in binary, and then the result is printed as hex.
• There is no connection between the format of the inputs (the hexadecimal literals) and the output, there is no such thing as a "hexadecimal number" in a Python variable.
• The hex() function can be used to convert any number into a hexadecimal string for display.

If you already have the numbers as strings, you can use the int() function to convert to numbers, by providing the expected base (16 for hexadecimal numbers):

>>> print int("12ef", 16)
4874

So you can do two conversions, perform the XOR, and then convert back to hex:

>>> print hex(int("12ef", 16) ^ int("abcd", 16))
0xb922

You're multipling your "1 + 0.01" times the growthRate list, not the item in the list you're iterating through. I've renamed i to rate and using that instead. See the updated code below:

def nestEgVariable(salary, save, growthRates):
    SavingsRecord = []
    fund = 0
    depositPerYear = salary * save * 0.01
    #    V-- rate is a clearer name than i here, since you're iterating through the rates contained in the growthRates list
    for rate in growthRates:  
        #                           V-- Use the `rate` item in the growthRate list you're iterating through rather than multiplying by the `growthRate` list itself.
        fund = fund * (1 + 0.01 * rate) + depositPerYear
        SavingsRecord += [fund,]
    return SavingsRecord 


print nestEgVariable(10000,10,[3,4,5,0,3])

You can do it programatically:

import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;

public class ActivityName extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // remove title
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.main);
    }
}

Or you can do it via your AndroidManifest.xml file:

<activity android:name=".ActivityName"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen">
</activity>

Edit: I added some lines so that you can show it in fullscreen, as it seems that's what you want.

F5 to run the current query is an easy win, after that, the generic MS editor commands of CTRL + K + C to comment out the selected text and then CTRL + K + U to uncomment.

Change permission for the key file with :

chmod 400 key-file-name.pem

Yes, ensure ENSURES it is run every time, so you don't need the file.close in the begin block.

By the way, a good way to test is to do:

begin
  # Raise an error here
  raise "Error!!"
rescue
  #handle the error here
ensure
  p "=========inside ensure block"
end

You can test to see if "=========inside ensure block" will be printed out when there is an exception. Then you can comment out the statement that raises the error and see if the ensure statement is executed by seeing if anything gets printed out.

Specifying a float by placing a '.' after the number will also cause it to default to float.

>>> 1 / 2
0

>>> 1. / 2.
0.5

As @Bruno suggested, using pytest fixtures is another solution that is accessible for both test classes or even just simple test functions. Here's an example testing python2.7 functions:

import pytest

@pytest.fixture(scope='function')
def some_resource(request):
    stuff_i_setup = ["I setup"]

    def some_teardown():
        stuff_i_setup[0] += " ... but now I'm torn down..."
        print stuff_i_setup[0]
    request.addfinalizer(some_teardown)

    return stuff_i_setup[0]

def test_1_that_needs_resource(some_resource):
    print some_resource + "... and now I'm testing things..."

So, running test_1... produces:

I setup... and now I'm testing things...
I setup ... but now I'm torn down...

Notice that stuff_i_setup is referenced in the fixture, allowing that object to be setup and torn down for the test it's interacting with. You can imagine this could be useful for a persistent object, such as a hypothetical database or some connection, that must be cleared before each test runs to keep them isolated.

Syntax to change column name in MySql:

alter table table_name change old_column_name new_column_name data_type(size);

Example:

alter table test change LowSal Low_Sal integer(4);

The 'Access-Control-Allow-Origin' header contains multiple values

when i received this error i spent tons of hours searching solution for this but nothing works, finally i found solution to this problem which is very simple. when ''Access-Control-Allow-Origin' header added more than one time to your response this error occur, check your apache.conf or httpd.conf (Apache server), server side script, and remove unwanted entry header from these files.

Note:

• Duration in milliseconds (1000ms = 1s)
• Second script uses the cos function. Example curve:

Angular itself doesn't provide if/else functionality, but you can get it by including this module:

https://github.com/zachsnow/ng-elif

In its own words, it's just "a simple collection of control flow directives: ng-if, ng-else-if, and ng-else." It's easy and intuitive to use.

Example:

<div ng-if="someCondition">
    ...
</div>
<div ng-else-if="someOtherCondition">
    ...
</div>
<div ng-else>
    ...
</div>

Its a very customizable to display PDF's directly in your browser. It basically hosts the PDF in a flash object if you are not opposed to that sort of thing.

Here is a sample from our corporate website.

The JPA 2.0 Specification states that:

• The entity class must have a no-arg constructor. It may have other constructors as well. The no-arg constructor must be public or protected.
• The entity class must a be top-level class. An enum or interface must not be designated as an entity.
• The entity class must not be final. No methods or persistent instance variables of the entity class may be final.
• If an entity instance is to be passed by value as a detached object (e.g., through a remote interface), the entity class must implement the Serializable interface.
• Both abstract and concrete classes can be entities. Entities may extend non-entity classes as well as entity classes, and non-entity classes may extend entity classes.

The specification contains no requirements about the implementation of equals and hashCode methods for entities, only for primary key classes and map keys as far as I know.

In your pattern, you simply want to match all text between the two tags. Thus, you could use for example a [\w\W] to match all characters.

function getTextBetweenTags($string, $tagname) {
    $pattern = "/<$tagname>([\w\W]*?)<\/$tagname>/";
    preg_match($pattern, $string, $matches);
    return $matches[1];
}
