Maybe you should assign the public key to the authorized_keys, the simple way to do this is using ssh-copy-id -i your-pub-key-file user@dest.

The server first tries to authenticate you by public key. That doesn't work (I guess you haven't set one up), so it then falls back to 'keyboard-interactive'. It should then ask you for a password, which presumably you're not getting right. Did you see a password prompt?

Another solution when a file pretends another extension

I use php inside of var.js file with this .htaccess.

<Files var.js>
    AddType application/x-httpd-php .js
</Files>

Then I write php code in the .js file

<?php
// This is a `.js` file but works with php
echo "var js_variable = '$php_variable';";

When I got the MIME type warning on Chrome, I fixed it by adding a Content-Type header line in the .js(but php) file.

<?php
header('Content-Type: application/javascript');        // <- Add this line
// This is a `.js` file but works with php
...

A browser won't execute .js file because apache sends the Content-Type header of the file as application/x-httpd-php that is defined in .htaccess. That's a security reason. But apache won't execute php as far as htaccess commands the impersonation, it's necessary. So we need to overwrite apache's Content-Type header with the php function header(). I guess that apache stops sending its own header when php sends it instead of apache before.

This is very much implementation specific, but the general idea is to allow providers to issue short term access tokens with long term refresh tokens. Why?

• Many providers support bearer tokens which are very weak security-wise. By making them short-lived and requiring refresh, they limit the time an attacker can abuse a stolen token.
• Large scale deployment don't want to perform a database lookup every API call, so instead they issue self-encoded access token which can be verified by decryption. However, this also means there is no way to revoke these tokens so they are issued for a short time and must be refreshed.
• The refresh token requires client authentication which makes it stronger. Unlike the above access tokens, it is usually implemented with a database lookup.

It is configured to use localhost:25 for the mail server.

The error message says that it can't connect to localhost:25.

Therefore you have two options:

1. Install / Properly configure an SMTP server on localhost port 25
2. Change the configuration to point to some other SMTP server that you can connect to

"The $.browser property is deprecated in jQuery 1.3, and its functionality may be moved to a team-supported plugin in a future release of jQuery."

See the MDN documentation on border.

I had the same issue. Changing

$.ajax(...)

to

jQuery.ajax(...)

did not work. But then I found that jQuery was included twice and removing one of them fixed the problem.

Edit: I misunderstood your question, I thought you were asking how to pad with spaces.

What you are asking is not possible using the string.Format alignment component; string.Format always pads with whitespace. See the Alignment Component section of MSDN: Composite Formatting.

According to Reflector, this is the code that runs inside StringBuilder.AppendFormat(IFormatProvider, string, object[]) which is called by string.Format:

int repeatCount = num6 - str2.Length;
if (!flag && (repeatCount > 0))
{
    this.Append(' ', repeatCount);
}
this.Append(str2);
if (flag && (repeatCount > 0))
{
    this.Append(' ', repeatCount);
}

As you can see, blanks are hard coded to be filled with whitespace.

I've tried all the possibilities. Nothing worked for me except the following. var element = document.querySelectorAll("input[id=btn1]"); element[0].setAttribute("disabled",true);

if [ ! -d directory ]; then
  mkdir directory
fi

or

mkdir -p directory

-p ensures creation if directory does not exist

You need to consider that GROUP BY happens after the WHERE clause conditions have been evaluated. And the WHERE clause always considers only one row, meaning that in your query, the meta_key conditions will always prevent any records from being selected, since one column cannot have multiple values for one row.

And what about the redundant meta_value checks? If a value is allowed to be both smaller and greater than a given value, then its actual value doesn't matter at all - the check can be omitted.

According to one of your comments you want to check for places less than a certain distance from a given location. To get correct distances, you'd actually have to use some kind of proper distance function (see e.g. this question for details). But this SQL should give you an idea how to start:

SELECT items.* FROM items i, meta_data m1, meta_data m2
    WHERE i.item_id = m1.item_id and i.item_id = m2.item_id
    AND m1.meta_key = 'lat' AND m1.meta_value >= 55 AND m1.meta_value <= 65
    AND m2.meta_key = 'lng' AND m2.meta_value >= 20 AND m2.meta_value <= 30

A small improvement to @FishBoy's suggestion is to use the id projection, so you don't have to hard-code the identifier property name.

criteria.setProjection(Projections.distinct(Projections.id()));

Use DATALENGTH method, for example:

SELECT length = DATALENGTH(myField)
FROM myTABLE

To copy all files, including hidden files use:

cp -r /home/server/folder/test/. /home/server/

#include<iostream>
#include<vector>
#include<string>
using namespace std;
int main()
{
    vector<string>V;
    int num;
    cin>>num;
    string input;
    while (cin>>input && num != 0) //enter any non-integer to end the loop!
{
    //cin>>input;
   V.push_back(input);
   num--;
   if(num==0)
   {
   vector<string>::iterator it;
    for(it=V.begin();it!=V.end();it++)
        cout<<*it<<endl;
   };

}
return 0;

};

Use the android.webkit.URLUtil on android:

URLUtil.isValidUrl(URL_STRING);

Note: It is just checking the initial scheme of URL, not that the entire URL is valid.

use CHAR(10) for New Line in SQL
char(9) for Tab
and Char(13) for Carriage Return

To encrypt:

byte[] encrpt= text.getBytes("UTF-8");
String base64 = Base64.encodeToString(encrpt, Base64.DEFAULT);

To decrypt:

byte[] decrypt= Base64.decode(base64, Base64.DEFAULT);
String text = new String(decrypt, "UTF-8");

The mimetypes module just recognise an file type based on file extension. If you will try to recover a file type of a file without extension, the mimetypes will not works.

You can simply use cells.select to select all cells in the worksheet. You can get a valid address by saying Range(Cells.Address).

If you want to find the last Used Range where you have made some formatting change or entered a value in you can call ActiveSheet.UsedRange and select it from there. Hope that helps

This is what I got from oracle documentation, but it is for oracle 10g release 2:

When you define a NUMBER variable, you can specify its precision (p) and scale (s) so that it is sufficiently, but not unnecessarily, large. Precision is the number of significant digits. Scale can be positive or negative. Positive scale identifies the number of digits to the right of the decimal point; negative scale identifies the number of digits to the left of the decimal point that can be rounded up or down.

The NUMBER data type is supported by Oracle Database standard libraries and operates the same way as it does in SQL. It is used for dimensions and surrogates when a text or INTEGER data type is not appropriate. It is typically assigned to variables that are not used for calculations (like forecasts and aggregations), and it is used for variables that must match the rounding behavior of the database or require a high degree of precision. When deciding whether to assign the NUMBER data type to a variable, keep the following facts in mind in order to maximize performance:

• Analytic workspace calculations on NUMBER variables is slower than other numerical data types because NUMBER values are calculated in software (for accuracy) rather than in hardware (for speed).
• When data is fetched from an analytic workspace to a relational column that has the NUMBER data type, performance is best when the data already has the NUMBER data type in the analytic workspace because a conversion step is not required.

I am using the following code in one of my current projects where i download data from the internet. It is all inside my activity class.

private class GetData extends AsyncTask<String, Void, JSONObject> {

        @Override
        protected void onPreExecute() {
            super.onPreExecute();

            progressDialog = ProgressDialog.show(Calendar.this,
                    "", "");

        }

        @Override
        protected JSONObject doInBackground(String... params) {

            String response;

            try {

                HttpClient httpclient = new DefaultHttpClient();

                HttpPost httppost = new HttpPost(url);

                HttpResponse responce = httpclient.execute(httppost);

                HttpEntity httpEntity = responce.getEntity();

                response = EntityUtils.toString(httpEntity);

                Log.d("response is", response);

                return new JSONObject(response);

            } catch (Exception ex) {

                ex.printStackTrace();

            }

            return null;
        }

        @Override
        protected void onPostExecute(JSONObject result) 
        {
            super.onPostExecute(result);

            progressDialog.dismiss();

            if(result != null)
            {
                try
                {
                    JSONObject jobj = result.getJSONObject("result");

                    String status = jobj.getString("status");

                    if(status.equals("true"))
                    {
                        JSONArray array = jobj.getJSONArray("data");

                        for(int x = 0; x < array.length(); x++)
                        {
                            HashMap<String, String> map = new HashMap<String, String>();

                            map.put("name", array.getJSONObject(x).getString("name"));

                            map.put("date", array.getJSONObject(x).getString("date"));

                            map.put("description", array.getJSONObject(x).getString("description"));

                            list.add(map);
                        }

                        CalendarAdapter adapter = new CalendarAdapter(Calendar.this, list);

                        list_of_calendar.setAdapter(adapter);
                    }
                }
                catch (Exception e) 
                {
                    e.printStackTrace();
                }
            }
            else
            {
                Toast.makeText(Calendar.this, "Network Problem", Toast.LENGTH_LONG).show();
            }
        }

    }

and execute it in OnCreate Method like new GetData().execute();

where Calendar is my calendarActivity and i have also created a CalendarAdapter to set these values to a list view.

Make use of Parameter Grouping (Laravel 4.2). For your example, it'd be something like this:

Model::where(function ($query) {
    $query->where('a', '=', 1)
          ->orWhere('b', '=', 1);
})->where(function ($query) {
    $query->where('c', '=', 1)
          ->orWhere('d', '=', 1);
});

Ember-Data's ActiveRecord adapter expects 422 UNPROCESSABLE ENTITY to be returned from server. So, if you're client is written in Ember.js you should use 422. Only then DS.Errors will be populated with returned errors. You can of course change 422 to any other code in your adapter.

h2 { display: inline }

If you get your local repo into a complete mess, then a reliable way to throw away local commits in Git is to...

1. Use "git config --get remote.origin.url" to get URL of remote origin
2. Rename local git folder to "my_broken_local_repo"
3. Use "git clone <url_from_1>" to get fresh local copy of remote git repository

In my experience Eclipse handles the world changing around it quite well. However, you may need to select affected projects in Eclipse and clean them to force Eclipse to rebuild them. I guess other IDEs may need a forced rebuild too.

A side benefit of the above procedure is that you will find out if your project relies on local files that were not put into git. If you find you are missing files then you can copy them in from "my_broken_local_repo" and add them to git. Once you have confidence that your new local repo has everything you need then you can delete "my_broken_local_repo".

To the people who might be searching for this issue still, are looking at this page only.

This will help you remove cached index files, and then only add the ones you need, including changes to your .gitignore file.

1. git rm -r --cached .  
2. git add .
3. git commit -m 'Removing ignored files'

Here is a little bit more info.

1. This command will remove all cached files from index.
2. This command will add all files except those which are mentioned in gitignore.
3. This command will commit your files again and remove the files you want git to ignore, but keep them in your local directory.

For me, the problem was having nested EAGER fetches.

One solution is to set the nested fields to LAZY and use Hibernate.initialize() to load the nested field(s):

x = session.get(ClassName.class, id);
Hibernate.initialize(x.getNestedField());

MVVM + WinForms FolderBrowserDialog as behavior

public class FolderDialogBehavior : Behavior<Button>
{
    public string SetterName { get; set; }

    protected override void OnAttached()
    {
        base.OnAttached();
        AssociatedObject.Click += OnClick;
    }

    protected override void OnDetaching()
    {
        AssociatedObject.Click -= OnClick;
    }

    private void OnClick(object sender, RoutedEventArgs e)
    {
        var dialog = new FolderBrowserDialog();
        var result = dialog.ShowDialog();
        if (result == DialogResult.OK && AssociatedObject.DataContext != null)
        {
            var propertyInfo = AssociatedObject.DataContext.GetType().GetProperties(BindingFlags.Instance | BindingFlags.Public)
            .Where(p => p.CanRead && p.CanWrite)
            .Where(p => p.Name.Equals(SetterName))
            .First();

            propertyInfo.SetValue(AssociatedObject.DataContext, dialog.SelectedPath, null);
        }
    }
}

Usage

     <Button Grid.Column="3" Content="...">
            <Interactivity:Interaction.Behaviors>
                <Behavior:FolderDialogBehavior SetterName="SomeFolderPathPropertyName"/>
            </Interactivity:Interaction.Behaviors>
     </Button>

Might be a bit odd or bad practice but this is one way of going about it.

(arg1, arg2, arg3) = (1, 2, 3)

if (arg1 == 1)*(arg2 == 2)*(arg3 == 3):
    print('Example.')

Anything multiplied by 0 == 0. If any of these conditions fail then it evaluates to false.

You can delete the archive files and executable binaries that go install (or go get) produces for a package with go clean -i importpath.... These normally reside under $GOPATH/pkg and $GOPATH/bin, respectively.

Be sure to include ... on the importpath, since it appears that, if a package includes an executable, go clean -i will only remove that and not archive files for subpackages, like gore/gocode in the example below.

Source code then needs to be removed manually from $GOPATH/src.

go clean has an -n flag for a dry run that prints what will be run without executing it, so you can be certain (see go help clean). It also has a tempting -r flag to recursively clean dependencies, which you probably don't want to actually use since you'll see from a dry run that it will delete lots of standard library archive files!

A complete example, which you could base a script on if you like:

$ go get -u github.com/motemen/gore

$ which gore
/Users/ches/src/go/bin/gore

$ go clean -i -n github.com/motemen/gore...
cd /Users/ches/src/go/src/github.com/motemen/gore
rm -f gore gore.exe gore.test gore.test.exe commands commands.exe commands_test commands_test.exe complete complete.exe complete_test complete_test.exe debug debug.exe helpers_test helpers_test.exe liner liner.exe log log.exe main main.exe node node.exe node_test node_test.exe quickfix quickfix.exe session_test session_test.exe terminal_unix terminal_unix.exe terminal_windows terminal_windows.exe utils utils.exe
rm -f /Users/ches/src/go/bin/gore
cd /Users/ches/src/go/src/github.com/motemen/gore/gocode
rm -f gocode.test gocode.test.exe
rm -f /Users/ches/src/go/pkg/darwin_amd64/github.com/motemen/gore/gocode.a

$ go clean -i github.com/motemen/gore...

$ which gore

$ tree $GOPATH/pkg/darwin_amd64/github.com/motemen/gore
/Users/ches/src/go/pkg/darwin_amd64/github.com/motemen/gore

0 directories, 0 files

# If that empty directory really bugs you...
$ rmdir $GOPATH/pkg/darwin_amd64/github.com/motemen/gore

$ rm -rf $GOPATH/src/github.com/motemen/gore

Note that this information is based on the go tool in Go version 1.5.1.

You can use DataGridViewColoumnHeaderMouseClick event like this :

Private string order = String.Empty;
private void dgvDepartment_ColumnHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
    if (order == "d")
{
        order = "a";                
dataGridView1.DataSource = students.Select(s => new { ID = s.StudentId, RUDE = s.RUDE, Nombre = s.Name, Apellidos = s.LastNameFather + " " + s.LastNameMother, Nacido = s.DateOfBirth })   .OrderBy(s => s.Apellidos).ToList();
    }
    else
    {
        order = "d";
        dataGridView1.DataSource = students.Select(s => new { ID = s.StudentId, RUDE = s.RUDE, Nombre = s.Name, Apellidos = s.LastNameFather + " " + s.LastNameMother, Nacido = s.DateOfBirth }.OrderByDescending(s => s.Apellidos)  .ToList()
    }
}

From official documentation

Warning: Do not filter files with binary content like images! This will most likely result in corrupt output.

If you have both text files and binary files as resources it is recommended to have two separated folders. One folder src/main/resources (default) for the resources which are not filtered and another folder src/main/resources-filtered for the resources which are filtered.

<project>
  ...
  <build>
    ...
    <resources>
      <resource>
        <directory>src/main/resources-filtered</directory>
        <filtering>true</filtering>
      </resource>
      ...
    </resources>
    ...
  </build>
  ...
</project>

Now you can put those files into src/main/resources which should not filtered and the other files into src/main/resources-filtered.

As already mentioned filtering binary files like images,pdf`s etc. could result in corrupted output. To prevent such problems you can configure file extensions which will not being filtered.

Most certainly, You have in your directory files that cannot be filtered. So you have to specify the extensions that has not be filtered.

The dangling images are ghosts from the previous builds and pulls, simply delete them with : docker rmi $(docker images -f "dangling=true" -q)

The problem with your macro is that once you have opened your destination Workbook (xlw in your code sample), it is set as the ActiveWorkbook object and you get an error because TextBox1 doesn't exist in that specific Workbook. To resolve this issue, you could define a reference object to your actual Workbook before opening the other one.

Sub UploadData()
    Dim xlo As New Excel.Application
    Dim xlw As New Excel.Workbook
    Dim myWb as Excel.Workbook

    Set myWb = ActiveWorkbook
    Set xlw = xlo.Workbooks.Open("c:\myworkbook.xlsx")
    xlo.Worksheets(1).Cells(2, 1) = myWb.ActiveSheet.Range("d4").Value
    xlo.Worksheets(1).Cells(2, 2) = myWb.ActiveSheet.TextBox1.Text

    xlw.Save
    xlw.Close
    Set xlo = Nothing
    Set xlw = Nothing
End Sub

If you prefer, you could also use myWb.Activate to put back your main Workbook as active. It will also work if you do it with a Worksheet object. Using one or another mostly depends on what you want to do (if there are multiple sheets, etc.).

OR

sudo apt-get remove mongodb* --purge

It will remove complete mongodb

It is also very important to distinguish a SENDING multicast socket from a RECEIVING multicast socket.

I agree with all the answers above regarding RECEIVING multicast sockets. The OP noted that binding a RECEIVING socket to an interface did not help. However, it is necessary to bind a multicast SENDING socket to an interface.

For a SENDING multicast socket on a multi-homed server, it is very important to create a separate socket for each interface you want to send to. A bound SENDING socket should be created for each interface.

  // This is a fix for that bug that causes Servers to pop offline/online.
  // Servers will intermittently pop offline/online for 10 seconds or so.
  // The bug only happens if the machine had a DHCP gateway, and the gateway is no longer accessible.
  // After several minutes, the route to the DHCP gateway may timeout, at which
  // point the pingponging stops.
  // You need 3 machines, Client machine, server A, and server B
  // Client has both ethernets connected, and both ethernets receiving CITP pings (machine A pinging to en0, machine B pinging to en1)
  // Now turn off the ping from machine B (en1), but leave the network connected.
  // You will notice that the machine transmitting on the interface with
  // the DHCP gateway will fail sendto() with errno 'No route to host'
  if ( theErr == 0 )
  {
     // inspired by 'ping -b' option in man page:      
     //      -b boundif
     //             Bind the socket to interface boundif for sending.
     struct sockaddr_in bindInterfaceAddr;
     bzero(&bindInterfaceAddr, sizeof(bindInterfaceAddr));
     bindInterfaceAddr.sin_len = sizeof(bindInterfaceAddr);
     bindInterfaceAddr.sin_family = AF_INET;
     bindInterfaceAddr.sin_addr.s_addr = htonl(interfaceipaddr);
     bindInterfaceAddr.sin_port = 0; // Allow the kernel to choose a random port number by passing in 0 for the port.
     theErr = bind(mSendSocketID, (struct sockaddr *)&bindInterfaceAddr, sizeof(bindInterfaceAddr));
     struct sockaddr_in serverAddress;
     int namelen = sizeof(serverAddress);  
     if (getsockname(mSendSocketID, (struct sockaddr *)&serverAddress, (socklen_t *)&namelen) < 0) {
        DLogErr(@"ERROR Publishing service... getsockname err");
     }
     else
     {
        DLog( @"socket %d bind, %@ port %d", mSendSocketID, [NSString stringFromIPAddress:htonl(serverAddress.sin_addr.s_addr)], htons(serverAddress.sin_port) );
     }

Without this fix, multicast sending will intermittently get sendto() errno 'No route to host'. If anyone can shed light on why unplugging a DHCP gateway causes Mac OS X multicast SENDING sockets to get confused, I would love to hear it.

Yacoby's answer inspires me to write an adaptor for encapsulating the functor boilerplate.

template< class T, bool (*comp)( T const &, T const & ) >
class set_funcomp {
    struct ftor {
        bool operator()( T const &l, T const &r )
            { return comp( l, r ); }
    };
public:
    typedef std::set< T, ftor > t;
};

// usage

bool my_comparison( foo const &l, foo const &r );
set_funcomp< foo, my_comparison >::t boo; // just the way you want it!

Wow, I think that was worth the trouble!

yourlabel.text = yourvariable

or self is use for when you are in async {brackets} or in some Extension

DispatchQueue.main.async{

var query = source.GroupBy(x => new { x.Column1, x.Column2 });

For those who have this problem with collection of enums here is how to solve it:

@Enumerated(EnumType.STRING)
@Column(name = "OPTION")
@CollectionTable(name = "MY_ENTITY_MY_OPTION")
@ElementCollection(targetClass = MyOptionEnum.class, fetch = EAGER)
Collection<MyOptionEnum> options;

FileNotFound in this case means you got a 404 from your server

You Have to Set the Request Content-Type Header Parameter Set “content-type” request header to “application/json” to send the request content in JSON form.

This parameter has to be set to send the request body in JSON format.

Failing to do so, the server returns HTTP status code “400-bad request”.

con.setRequestProperty("Content-Type", "application/json; utf-8");

Looks like what you want is Deep Copy of the object. Why not use Object.assign()? No libaries needed, and its a one-liner :)

getGenericItems(selected: Item) {
    this.itemService.getGenericItems(selected).subscribe(
        result => {
            this.genericItems = result;
            this.backupDate = Object.assign({}, result); 
            //this.backupdate WILL NOT share the same memory locations as this.genericItems
            //modifying this.genericItems WILL NOT modify this.backupdate
        });
}

Try Portable UTF-8:

$str = utf8_chr( 0x1000 );
$str = utf8_chr( '\u1000' );
$str = utf8_chr( 4096 );

All work exactly the same way. You can get the codepoint of a character with utf8_ord(). Read more about Portable UTF-8.

Using Java Streams you can just use an IntStream mapping the objects:

JSONArray array = new JSONArray(jsonString);
List<String> result = IntStream.range(0, array.length())
        .mapToObj(array::get)
        .map(Object::toString)
        .collect(Collectors.toList());

It could be improved upon in many ways, but it might get you started.

The index method of a list will do this for you. If you want to guarantee order, sort the list first using sorted(). Sorted accepts a cmp or key parameter to dictate how the sorting will happen:

a = [5, 4, 3]
print sorted(a).index(5)

Or:

a = ['one', 'aardvark', 'a']
print sorted(a, key=len).index('a')

If the underlying goal is "How can I start a container when Docker starts?"

We can use Docker's restart policy

To add a restart policy to an existing container:

Docker: Add a restart policy to a container that was already created

Example:

docker update --restart=always <container>

You can go to IE Tools -> Internet options -> Advanced Tab. Under Advanced, check for security and put a check on the 1st 2 options which says,"Allow active content from CDs to run on My Computer* and Allow active content to run in files on My Computer*"

Restart your browser and the ActiveX scripts will not be shown.

To really understand what we're talking about when we talk about self versus $this, we need to actually dig into what's going on at a conceptual and a practical level. I don't really feel any of the answers do this appropriately, so here's my attempt.

Let's start off by talking about what a class and an object is.

Classes And Objects, Conceptually

So, what is a class? A lot of people define it as a blueprint or a template for an object. In fact, you can read more About Classes In PHP Here. And to some extent that's what it really is. Let's look at a class:

class Person {
    public $name = 'my name';
    public function sayHello() {
        echo "Hello";
    }
}

As you can tell, there is a property on that class called $name and a method (function) called sayHello().

It's very important to note that the class is a static structure. Which means that the class Person, once defined, is always the same everywhere you look at it.

An object on the other hand is what's called an instance of a Class. What that means is that we take the "blueprint" of the class, and use it to make a dynamic copy. This copy is now specifically tied to the variable it's stored in. Therefore, any changes to an instance is local to that instance.

$bob = new Person;
$adam = new Person;
$bob->name = 'Bob';
echo $adam->name; // "my name"

We create new instances of a class using the new operator.

Therefore, we say that a Class is a global structure, and an Object is a local structure. Don't worry about that funny -> syntax, we're going to go into that in a little bit.

One other thing we should talk about, is that we can check if an instance is an instanceof a particular class: $bob instanceof Person which returns a boolean if the $bob instance was made using the Person class, or a child of Person.

Defining State

So let's dig a bit into what a class actually contains. There are 5 types of "things" that a class contains:

1. Properties - Think of these as variables that each instance will contain.

   class Foo {
       public $bar = 1;
   }
   

2. Static Properties - Think of these as variables that are shared at the class level. Meaning that they are never copied by each instance.

   class Foo {
       public static $bar = 1;
   }
   

3. Methods - These are functions which each instance will contain (and operate on instances).

   class Foo {
       public function bar() {}
   }
   

4. Static Methods - These are functions which are shared across the entire class. They do not operate on instances, but instead on the static properties only.

   class Foo {
       public static function bar() {}
   }
   

5. Constants - Class resolved constants. Not going any deeper here, but adding for completeness:

   class Foo {
       const BAR = 1;
   }
   

So basically, we're storing information on the class and object container using "hints" about static which identify whether the information is shared (and hence static) or not (and hence dynamic).

State and Methods

Inside of a method, an object's instance is represented by the $this variable. The current state of that object is there, and mutating (changing) any property will result in a change to that instance (but not others).

If a method is called statically, the $this variable is not defined. This is because there's no instance associated with a static call.

The interesting thing here is how static calls are made. So let's talk about how we access the state:

Accessing State

So now that we have stored that state, we need to access it. This can get a bit tricky (or way more than a bit), so let's split this into two viewpoints: from outside of an instance/class (say from a normal function call, or from the global scope), and inside of an instance/class (from within a method on the object).

From Outside Of An Instance/Class

From the outside of an instance/class, our rules are quite simple and predictable. We have two operators, and each tells us immediately if we're dealing with an instance or a class static:

• -> - object-operator - This is always used when we're accessing an instance.

  $bob = new Person;
  echo $bob->name;
  

  It's important to note that calling Person->foo does not make sense (since Person is a class, not an instance). Therefore, that is a parse error.

• :: - scope-resolution-operator - This is always used to access a Class static property or method.

  echo Foo::bar()
  

  Additionally, we can call a static method on an object in the same way:

  echo $foo::bar()
  

  It's extremely important to note that when we do this from outside, the object's instance is hidden from the bar() method. Meaning that it's the exact same as running:

  $class = get_class($foo);
  $class::bar();
  

Therefore, $this is not defined in the static call.

From Inside Of An Instance/Class

Things change a bit here. The same operators are used, but their meaning becomes significantly blurred.

The object-operator -> is still used to make calls to the object's instance state.

class Foo {
    public $a = 1;
    public function bar() {
        return $this->a;
    }
}

Calling the bar() method on $foo (an instance of Foo) using the object-operator: $foo->bar() will result in the instance's version of $a.

So that's how we expect.

The meaning of the :: operator though changes. It depends on the context of the call to the current function:

• Within a static context

  Within a static context, any calls made using :: will also be static. Let's look at an example:

  class Foo {
      public function bar() {
          return Foo::baz();
      }
      public function baz() {
          return isset($this);
      }
  }
  

  Calling Foo::bar() will call the baz() method statically, and hence $this will not be populated. It's worth noting that in recent versions of PHP (5.3+) this will trigger an E_STRICT error, because we're calling non-static methods statically.

• Within an instance context

  Within an instance context on the other hand, calls made using :: depend on the receiver of the call (the method we're calling). If the method is defined as static, then it will use a static call. If it's not, it will forward the instance information.

  So, looking at the above code, calling $foo->bar() will return true, since the "static" call happens inside of an instance context.

Make sense? Didn't think so. It's confusing.

Short-Cut Keywords

Because tying everything together using class names is rather dirty, PHP provides 3 basic "shortcut" keywords to make scope resolving easier.

• self - This refers to the current class name. So self::baz() is the same as Foo::baz() within the Foo class (any method on it).

• parent - This refers to the parent of the current class.

• static - This refers to the called class. Thanks to inheritance, child classes can override methods and static properties. So calling them using static instead of a class name allows us to resolve where the call came from, rather than the current level.

Examples

The easiest way to understand this is to start looking at some examples. Let's pick a class:

class Person {
    public static $number = 0;
    public $id = 0;
    public function __construct() {
        self::$number++;
        $this->id = self::$number;
    }
    public $name = "";
    public function getName() {
        return $this->name;
    }
    public function getId() {
        return $this->id;
    }
}

class Child extends Person {
    public $age = 0;
    public function __construct($age) {
        $this->age = $age;
        parent::__construct();
    }
    public function getName() {
        return 'child: ' . parent::getName();
    }
}

Now, we're also looking at inheritance here. Ignore for a moment that this is a bad object model, but let's look at what happens when we play with this:

$bob = new Person;
$bob->name = "Bob";
$adam = new Person;
$adam->name = "Adam";
$billy = new Child;
$billy->name = "Billy";
var_dump($bob->getId()); // 1
var_dump($adam->getId()); // 2
var_dump($billy->getId()); // 3

So the ID counter is shared across both instances and the children (because we're using self to access it. If we used static, we could override it in a child class).

var_dump($bob->getName()); // Bob
var_dump($adam->getName()); // Adam
var_dump($billy->getName()); // child: Billy

Note that we're executing the Person::getName() instance method every time. But we're using the parent::getName() to do it in one of the cases (the child case). This is what makes this approach powerful.

Word Of Caution #1

Note that the calling context is what determines if an instance is used. Therefore:

class Foo {
    public function isFoo() {
        return $this instanceof Foo;
    }
}

Is not always true.

class Bar {
    public function doSomething() {
        return Foo::isFoo();
    }
}
$b = new Bar;
var_dump($b->doSomething()); // bool(false)

Now it is really weird here. We're calling a different class, but the $this that gets passed to the Foo::isFoo() method is the instance of $bar.

This can cause all sorts of bugs and conceptual WTF-ery. So I'd highly suggest avoiding the :: operator from within instance methods on anything except those three virtual "short-cut" keywords (static, self, and parent).

Word Of Caution #2

Note that static methods and properties are shared by everyone. That makes them basically global variables. With all the same problems that come with globals. So I would be really hesitant to store information in static methods/properties unless you're comfortable with it being truly global.

Word Of Caution #3

In general you'll want to use what's known as Late-Static-Binding by using static instead of self. But note that they are not the same thing, so saying "always use static instead of self is really short-sighted. Instead, stop and think about the call you want to make and think if you want child classes to be able to override that static resolved call.

TL/DR

Too bad, go back and read it. It may be too long, but it's that long because this is a complex topic

TL/DR #2

Ok, fine. In short, self is used to reference the current class name within a class, where as $this refers to the current object instance. Note that self is a copy/paste short-cut. You can safely replace it with your class name, and it'll work fine. But $this is a dynamic variable that can't be determined ahead of time (and may not even be your class).

TL/DR #3

If the object-operator is used (->), then you always know you're dealing with an instance. If the scope-resolution-operator is used (::), you need more information about the context (are we in an object-context already? Are we outside of an object? etc).

The way to do was looking at the code in code/core/Mage/Catalog/Model/Resource/Category/Flat/Collection.php at line 380 in Magento 1.7.2 on the function setPage($pageNum, $pageSize)

 $collection = Mage::getModel('model')
     ->getCollection()
     ->setCurPage(2) // 2nd page
     ->setPageSize(10); // 10 elements per pages

I hope this will help someone.

It May be due to some exceptions like (Parsing NUMERIC to String or vise versa).

Please verify cell values either are null or do handle Exception and see.

Ok, I don't normally answer my own questions but after a bit of tinkering, I have figured out definitively how Oracle stores the result of a DATE subtraction.

When you subtract 2 dates, the value is not a NUMBER datatype (as the Oracle 11.2 SQL Reference manual would have you believe). The internal datatype number of a DATE subtraction is 14, which is a non-documented internal datatype (NUMBER is internal datatype number 2). However, it is actually stored as 2 separate two's complement signed numbers, with the first 4 bytes used to represent the number of days and the last 4 bytes used to represent the number of seconds.

An example of a DATE subtraction resulting in a positive integer difference:

select date '2009-08-07' - date '2008-08-08' from dual;

Results in:

DATE'2009-08-07'-DATE'2008-08-08'
---------------------------------
                              364

select dump(date '2009-08-07' - date '2008-08-08') from dual;

DUMP(DATE'2009-08-07'-DATE'2008
-------------------------------
Typ=14 Len=8: 108,1,0,0,0,0,0,0

Recall that the result is represented as a 2 seperate two's complement signed 4 byte numbers. Since there are no decimals in this case (364 days and 0 hours exactly), the last 4 bytes are all 0s and can be ignored. For the first 4 bytes, because my CPU has a little-endian architecture, the bytes are reversed and should be read as 1,108 or 0x16c, which is decimal 364.

An example of a DATE subtraction resulting in a negative integer difference:

select date '1000-08-07' - date '2008-08-08' from dual;

Results in:

DATE'1000-08-07'-DATE'2008-08-08'
---------------------------------
                          -368160

select dump(date '1000-08-07' - date '2008-08-08') from dual;

DUMP(DATE'1000-08-07'-DATE'2008-08-0
------------------------------------
Typ=14 Len=8: 224,97,250,255,0,0,0,0

Again, since I am using a little-endian machine, the bytes are reversed and should be read as 255,250,97,224 which corresponds to 11111111 11111010 01100001 11011111. Now since this is in two's complement signed binary numeral encoding, we know that the number is negative because the leftmost binary digit is a 1. To convert this into a decimal number we would have to reverse the 2's complement (subtract 1 then do the one's complement) resulting in: 00000000 00000101 10011110 00100000 which equals -368160 as suspected.

An example of a DATE subtraction resulting in a decimal difference:

select to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS'
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS') from dual;

TO_DATE('08/AUG/200414:00:00','DD/MON/YYYYHH24:MI:SS')-TO_DATE('08/AUG/20048:00:
--------------------------------------------------------------------------------
                                                                             .25

The difference between those 2 dates is 0.25 days or 6 hours.

select dump(to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS')
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS')) from dual;

DUMP(TO_DATE('08/AUG/200414:00:
-------------------------------
Typ=14 Len=8: 0,0,0,0,96,84,0,0

Now this time, since the difference is 0 days and 6 hours, it is expected that the first 4 bytes are 0. For the last 4 bytes, we can reverse them (because CPU is little-endian) and get 84,96 = 01010100 01100000 base 2 = 21600 in decimal. Converting 21600 seconds to hours gives you 6 hours which is the difference which we expected.

Hope this helps anyone who was wondering how a DATE subtraction is actually stored.

You get the syntax error because the date math does not return a NUMBER, but it returns an INTERVAL:

SQL> SELECT DUMP(SYSDATE - start_date) from test;

DUMP(SYSDATE-START_DATE)
-------------------------------------- 
Typ=14 Len=8: 188,10,0,0,223,65,1,0

You need to convert the number in your example into an INTERVAL first using the NUMTODSINTERVAL Function

For example:

SQL> SELECT (SYSDATE - start_date) DAY(5) TO SECOND from test;

(SYSDATE-START_DATE)DAY(5)TOSECOND
----------------------------------
+02748 22:50:04.000000

SQL> SELECT (SYSDATE - start_date) from test;

(SYSDATE-START_DATE)
--------------------
           2748.9515

SQL> select NUMTODSINTERVAL(2748.9515, 'day') from dual;

NUMTODSINTERVAL(2748.9515,'DAY')
--------------------------------
+000002748 22:50:09.600000000

SQL>

Based on the reverse cast with the NUMTODSINTERVAL() function, it appears some rounding is lost in translation.

If .java file contains top level (not nested) public class, it have same name as that public class. So if you have class like public class A{...} it needs to be placed in A.java file. Because of that we can't have two public classes in one .java file.

If having two public classes would be allowed then, and lets say aside from public A class file would also contain public class B{} it would require from A.java file to be also named as B.java but files can't have two (or more) names (at least in all systems on which Java can be run).

So assuming your code is placed in StaticDemoShow.java file you have two options:

1. If you want to have other class in same file make them non-public (lack of visibility modifier will represent default/package-private visibility)

   class StaticDemo { // It can no longer public
   
       static int a = 3;
       static int b = 4;
   
       static {
           System.out.println("Voila! Static block put into action");
       }
   
       static void show() {
           System.out.println("a= " + a);
           System.out.println("b= " + b);
       }
   
   }
   
   public class StaticDemoShow { // Only one top level public class in same .java file
       public static void main() {
           StaticDemo.show();
       }
   }
   

2. Move all public classes to their own .java files. So in your case you would need to split it into two files:

   • StaticDemo.java

     public class StaticDemo { // Note: same name as name of file
     
         static int a = 3;
         static int b = 4;
     
         static {
             System.out.println("Voila! Static block put into action");
         }
     
         static void show() {
             System.out.println("a= " + a);
             System.out.println("b= " + b);
         }
     
     }
     

   • StaticDemoShow.java

     public class StaticDemoShow { 
         public static void main() {
             StaticDemo.show();
         }
     }
     

The trick to triggering an asynchronous stylesheet download is to use a <link> element and set an invalid value for the media attribute (I'm using media="none", but any value will do). When a media query evaluates to false, the browser will still download the stylesheet, but it won't wait for the content to be available before rendering the page.

<link rel="stylesheet" href="css.css" media="none">

Once the stylesheet has finished downloading the media attribute must be set to a valid value so the style rules will be applied to the document. The onload event is used to switch the media property to all:

<link rel="stylesheet" href="css.css" media="none" onload="if(media!='all')media='all'">

This method of loading CSS will deliver useable content to visitors much quicker than the standard approach. Critical CSS can still be served with the usual blocking approach (or you can inline it for ultimate performance) and non-critical styles can be progressively downloaded and applied later in the parsing / rendering process.

This technique uses JavaScript, but you can cater for non-JavaScript browsers by wrapping the equivalent blocking <link> elements in a <noscript> element:

<link rel="stylesheet" href="css.css" media="none" onload="if(media!='all')media='all'"><noscript><link rel="stylesheet" href="css.css"></noscript>

I've join some informations posted here and the possibility of personalize components with Angular Material and this is my contribution without external libs and feedback with the name of the chosen file into field:

HTML

<mat-form-field class="columns">
    <mat-label *ngIf="selectedFiles; else newFile">{{selectedFiles.item(0).name}}</mat-label>
    <ng-template #newFile>
        <mat-label>Choose file</mat-label>
    </ng-template>
    <input matInput disabled>
    <button mat-icon-button matSuffix (click)="fileInput.click()">
        <mat-icon>attach_file</mat-icon>
    </button>
    <input hidden (change)="selectFile($event)" #fileInput type="file" id="file">
</mat-form-field>

TS

selectFile(event) {
    this.selectedFiles = event.target.files;
}

By 'return non-false', they mean to return any value which would not work out to boolean false. So you could return true, 1, 'non-false', or whatever else you can think up.

You can use the contains selector to search for elements containing a specific text

var elem = $('div.text_div:contains("This div contains some text")')?;
elem.text(elem.text().replace("contains", "Hello everyone"));

Add a vertical-align property to the TD, like this:

<td style="width: 259px; vertical-align: top;">
main page
</td>

As it was said already @INC is an array and you're free to add anything you want.

My CGI REST script looks like:

#!/usr/bin/perl
use strict;
use warnings;
BEGIN {
    push @INC, 'fully_qualified_path_to_module_wiht_our_REST.pm';
}
use Modules::Rest;
gone(@_);

Subroutine gone is exported by Rest.pm.

error_reporting(E_ALL ^ E_WARNING);

Had the same problem. The solution is to add a \ at the end of %ANT_HOME%\bin so it became %ANT_HOME%\bin\

Worked for me. (Should be system var)

I open a text editor, in my case I used Atom. Paste this code

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(1337, '127.0.0.1');
console.log('Server running at http://127.0.0.1:1337/');

and save as

helloworld.js

in

c:\xampp\htdocs\myproject 

directory. Next I open node.js commamd prompt enter

cd c:\xampp\htdocs\myproject

next

node helloworld.js

next I open my chrome browser and I type

http://localhost:1337

and there it is.

Some times If you touch the keyboard accidentally and removed a space.

if [ "$myvar" = "something"]; then
    do something
fi

Will trigger this error message. Note the space before ']' is required.

Here is a very quick and simple solution:

self.navigationController.hidesBarsOnTap = YES;

This will work on single tap instead of double tap. Also it will change the behavior for the navigation controller even after pushing or popping the current view controller.

You can always modify this behavior in your controller within the viewWillAppear: and viewWillDisappear: actions if you would like to set the behavior only for a single view controller.

Here is the documentation:

As addition to the other answers, in a cpanel installation, the mysql root password is stored in a file named /root/.my.cnf. (and the cpanel service resets it back on change, so the other answers here won't help)

What basically happens is,According to default updatePolicy of maven.Maven will fetch the jars from repo on daily basis.So if during 1st attempt your internet was not working then it would not try to fetch this jar again untill 24hours spent.

Resolution :

Either use

mvn -U clean install

where -U will force update the repo

or use

<profiles>
    <profile>
      ...
      <repositories>
        <repository>
          <id>myRepo</id>
          <name>My Repository</name>
          <releases>
            <enabled>false</enabled>
            <updatePolicy>always</updatePolicy>
            <checksumPolicy>warn</checksumPolicy>
          </releases>
         </repository>
      </repositories>
      ...
    </profile>
  </profiles>

in your settings.xml

@Controller
public abstract class AbstractController {
    @ModelAttribute("loggedUser")
    public User getLoggedUser() {
        return (User)SecurityContextHolder.getContext().getAuthentication().getPrincipal();

}

Use RAII

• Forget Garbage Collection (Use RAII instead). Note that even the Garbage Collector can leak, too (if you forget to "null" some references in Java/C#), and that Garbage Collector won't help you to dispose of resources (if you have an object which acquired a handle to a file, the file won't be freed automatically when the object will go out of scope if you don't do it manually in Java, or use the "dispose" pattern in C#).
• Forget the "one return per function" rule. This is a good C advice to avoid leaks, but it is outdated in C++ because of its use of exceptions (use RAII instead).
• And while the "Sandwich Pattern" is a good C advice, it is outdated in C++ because of its use of exceptions (use RAII instead).

This post seem to be repetitive, but in C++, the most basic pattern to know is RAII.

Learn to use smart pointers, both from boost, TR1 or even the lowly (but often efficient enough) auto_ptr (but you must know its limitations).

RAII is the basis of both exception safety and resource disposal in C++, and no other pattern (sandwich, etc.) will give you both (and most of the time, it will give you none).

See below a comparison of RAII and non RAII code:

void doSandwich()
{
   T * p = new T() ;
   // do something with p
   delete p ; // leak if the p processing throws or return
}

void doRAIIDynamic()
{
   std::auto_ptr<T> p(new T()) ; // you can use other smart pointers, too
   // do something with p
   // WON'T EVER LEAK, even in case of exceptions, returns, breaks, etc.
}

void doRAIIStatic()
{
   T p ;
   // do something with p
   // WON'T EVER LEAK, even in case of exceptions, returns, breaks, etc.
}

About RAII

To summarize (after the comment from Ogre Psalm33), RAII relies on three concepts:

• Once the object is constructed, it just works! Do acquire resources in the constructor.
• Object destruction is enough! Do free resources in the destructor.
• It's all about scopes! Scoped objects (see doRAIIStatic example above) will be constructed at their declaration, and will be destroyed the moment the execution exits the scope, no matter how the exit (return, break, exception, etc.).

This means that in correct C++ code, most objects won't be constructed with new, and will be declared on the stack instead. And for those constructed using new, all will be somehow scoped (e.g. attached to a smart pointer).

As a developer, this is very powerful indeed as you won't need to care about manual resource handling (as done in C, or for some objects in Java which makes intensive use of try/finally for that case)...

Edit (2012-02-12)

"scoped objects ... will be destructed ... no matter the exit" that's not entirely true. there are ways to cheat RAII. any flavour of terminate() will bypass cleanup. exit(EXIT_SUCCESS) is an oxymoron in this regard.

– wilhelmtell

wilhelmtell is quite right about that: There are exceptional ways to cheat RAII, all leading to the process abrupt stop.

Those are exceptional ways because C++ code is not littered with terminate, exit, etc., or in the case with exceptions, we do want an unhandled exception to crash the process and core dump its memory image as is, and not after cleaning.

But we must still know about those cases because, while they rarely happen, they can still happen.

(who calls terminate or exit in casual C++ code?... I remember having to deal with that problem when playing with GLUT: This library is very C-oriented, going as far as actively designing it to make things difficult for C++ developers like not caring about stack allocated data, or having "interesting" decisions about never returning from their main loop... I won't comment about that).

Changing the IDENTITY property is really a metadata only change. But to update the metadata directly requires starting the instance in single user mode and messing around with some columns in sys.syscolpars and is undocumented/unsupported and not something I would recommend or will give any additional details about.

For people coming across this answer on SQL Server 2012+ by far the easiest way of achieving this result of an auto incrementing column would be to create a SEQUENCE object and set the next value for seq as the column default.

Alternatively, or for previous versions (from 2005 onwards), the workaround posted on this connect item shows a completely supported way of doing this without any need for size of data operations using ALTER TABLE...SWITCH. Also blogged about on MSDN here. Though the code to achieve this is not very simple and there are restrictions - such as the table being changed can't be the target of a foreign key constraint.

Example code.

Set up test table with no identity column.

CREATE TABLE dbo.tblFoo 
(
bar INT PRIMARY KEY,
filler CHAR(8000),
filler2 CHAR(49)
)


INSERT INTO dbo.tblFoo (bar)
SELECT TOP (10000) ROW_NUMBER() OVER (ORDER BY (SELECT 0))
FROM master..spt_values v1, master..spt_values v2

Alter it to have an identity column (more or less instant).

BEGIN TRY;
    BEGIN TRANSACTION;

    /*Using DBCC CHECKIDENT('dbo.tblFoo') is slow so use dynamic SQL to
      set the correct seed in the table definition instead*/
    DECLARE @TableScript nvarchar(max)
    SELECT @TableScript = 
    '
    CREATE TABLE dbo.Destination(
        bar INT IDENTITY(' + 
                     CAST(ISNULL(MAX(bar),0)+1 AS VARCHAR) + ',1)  PRIMARY KEY,
        filler CHAR(8000),
        filler2 CHAR(49)
        )

        ALTER TABLE dbo.tblFoo SWITCH TO dbo.Destination;
    '       
    FROM dbo.tblFoo
    WITH (TABLOCKX,HOLDLOCK)

    EXEC(@TableScript)


    DROP TABLE dbo.tblFoo;

    EXECUTE sp_rename N'dbo.Destination', N'tblFoo', 'OBJECT';


    COMMIT TRANSACTION;
END TRY
BEGIN CATCH
    IF XACT_STATE() <> 0 ROLLBACK TRANSACTION;
    PRINT ERROR_MESSAGE();
END CATCH;

Test the result.

INSERT INTO dbo.tblFoo (filler,filler2) 
OUTPUT inserted.*
VALUES ('foo','bar')

Gives

bar         filler    filler2
----------- --------- ---------
10001       foo       bar      

Clean up

DROP TABLE dbo.tblFoo

If you want something like global constants; a quick an dirty way is to put the constant declarations into the pch file.

Using a fadeTo() that is fading to an opacity of 500 in 2 seconds in "I Can Has Kittenz"'s code isn't readable to me. I think it's better using other options like a delay()

$(".alert").delay(4000).slideUp(200, function() {
    $(this).alert('close');
});

To remove specific values: SharedPreferences.Editor.remove() followed by a commit()

To remove them all SharedPreferences.Editor.clear() followed by a commit()

If you don't care about the return value and you're using this from your application's main thread, consider using apply() instead.

The only way not to capture something is using look-around assertions:

(?<=123-)((apple|banana)(?=-456)|(?=456))

Because even with non-capturing groups (?:…) the whole regular expression captures their matched contents. But this regular expression matches only apple or banana if it’s preceded by 123- and followed by -456, or it matches the empty string if it’s preceded by 123- and followed by 456.

|Lookaround  |    Name      |        What it Does                       |
-----------------------------------------------------------------------
|(?=foo)     |   Lookahead  | Asserts that what immediately FOLLOWS the |
|            |              |  current position in the string is foo    |
-------------------------------------------------------------------------
|(?<=foo)    |   Lookbehind | Asserts that what immediately PRECEDES the|
|            |              |  current position in the string is foo    |
-------------------------------------------------------------------------
|(?!foo)     |   Negative   | Asserts that what immediately FOLLOWS the |
|            |   Lookahead  |  current position in the string is NOT foo|
-------------------------------------------------------------------------
|(?<!foo)    |   Negative   | Asserts that what immediately PRECEDES the|
|            |   Lookbehind |  current position in the string is NOT foo|
-------------------------------------------------------------------------

Assuming you have a form like this:

<form id="myForm" action="foo.php" method="post">
   <input type="text" value="" />
   <input type="submit" value="submit form" />

</form>

You can attach a onsubmit-event with jQuery like this:

$('#myForm').submit(function() {
  alert('Handler for .submit() called.');
  return false;
});

If you return false the form won't be submitted after the function, if you return true or nothing it will submit as usual.

See the jQuery documentation for more info.

You can't mix in stored procedures with ordinary SQL, whilst with stored function you can.

e.g. SELECT get_foo(myColumn) FROM mytable is not valid if get_foo() is a procedure, but you can do that if get_foo() is a function. The price is that functions have more limitations than a procedure.

I would implement a simple function to wrap the host system's sleep function in C.

I have this same problem, and I have successfully solved this problem. All you have to do is just change the elevation to 0 floating point value in that activity in which you want to remove the elevation.

If you want to change it in an activity called MyActivity.java so you have to get the ActionBar first.

First import the ActionBar class

import android.support.v7.app.ActionBar;

after importing you have to initialize a variable of action bar and set its elevation to 0.

 private ActionBar toolbar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    .
    .
    toolbar=getSupportActionBar();
    toolbar.setElevation(0);
    .
    .
    }

You can find that row with

DataRow row = table.Select("Product_id=2").FirstOrDefault();

and update it

row["Product_name"] = "cde";

Another nice way to time things is to use the with python structure.

with structure is automatically calling __enter__ and __exit__ methods which is exactly what we need to time things.

Let's create a Timer class.

from time import time

class Timer():
    def __init__(self, message):
        self.message = message
    def __enter__(self):
        self.start = time()
        return None  # could return anything, to be used like this: with Timer("Message") as value:
    def __exit__(self, type, value, traceback):
        elapsed_time = (time() - self.start) * 1000
        print(self.message.format(elapsed_time))

Then, one can use the Timer class like this:

with Timer("Elapsed time to compute some prime numbers: {}ms"):
    primes = []
    for x in range(2, 500):
        if not any(x % p == 0 for p in primes):
            primes.append(x)

there is no way to specifically target an element with php, you can either embed the php code between a div tag or use jquery which would be longer.

I had this problem earlier and this was my solution.

With Worksheets("Sheet1").Columns(5)
    .NumberFormat = "0"
    .Value = .Value
End With

I have tried all the solutions and this one worked for me

let temp = base64String.components(separatedBy: ",")
let dataDecoded : Data = Data(base64Encoded: temp[1], options: 
 .ignoreUnknownCharacters)!
let decodedimage = UIImage(data: dataDecoded)

yourImage.image = decodedimage

Replace a Fragment using following code:

Fragment fragment = new AddPaymentFragment();
getSupportFragmentManager().beginTransaction().replace(R.id.frame, fragment, "Tag_AddPayment")
                .addToBackStack("Tag_AddPayment")
                .commit();

Activity's onBackPressed() is :

  @Override
public void onBackPressed() {
    android.support.v4.app.FragmentManager fm = getSupportFragmentManager();
    if (fm.getBackStackEntryCount() > 1) {

        fm.popBackStack();
    } else {


        finish();

    }
    Log.e("popping BACKSTRACK===> ",""+fm.getBackStackEntryCount());

}

If you got only one column in the range to clean, just add "(1)" to the end. It indicates in wich column of the range Excel will remove the duplicates. Something like:

 Sub norepeat()

    Range("C8:C16").RemoveDuplicates (1)

End Sub

Is it possible to make a search by querySelectorAll using multiple unrelated conditions?

Yes, because querySelectorAll accepts full CSS selectors, and CSS has the concept of selector groups, which lets you specify more than one unrelated selector. For instance:

var list = document.querySelectorAll("form, p, legend");

...will return a list containing any element that is a form or p or legend.

CSS also has the other concept: Restricting based on more criteria. You just combine multiple aspects of a selector. For instance:

var list = document.querySelectorAll("div.foo");

...will return a list of all div elements that also (and) have the class foo, ignoring other div elements.

You can, of course, combine them:

var list = document.querySelectorAll("div.foo, p.bar, div legend");

...which means "Include any div element that also has the foo class, any p element that also has the bar class, and any legend element that's also inside a div."

You need to change permissions on the folder bootstrap/css. Your super user may be able to access it but it doesn't mean apache or nginx have access to it, that's why you still need to change the permissions.

Tip: I usually make the apache/nginx's user group owner of that kind of folders and give 775 permission to it.

As previously mentioned, this issue can be seen if you have multiple files with the same name, but in different groups (yellow folders) in the project navigator. In my case, this was intentional as I had multiple subdirectories each with a "preview.jpg" that I wanted copying to the app bundle:

In this situation, you need to ensure that Xcode recognises the directory reference (blue folder icon), not just the groups.

Remove the offending files and choose "Remove Reference" (so we don't delete them entirely):

Re-add them to the project by dragging them back into the project navigator. In the dialog that appears, choose "Create folder references for any added folders":

Notice that the files now have a blue folder icon in the project navigator:

If you now look under the "Copy Bundle Resources" section of the target's build phases, you will notice that there is a single entry for the entire folder, rather than entries for each item contained within the directory. The compiler will not complain about multiple build commands for those files.

Any variable declared outside of a function is assumed to be global, it's only when declaring them from inside of functions (except constructors) that you must specify that the variable be global.

Adding a few more points to Jason's Answer :

For taking all user provided arguments : user_args = sys.argv[1:]

Consider the sys.argv as a list of strings as (mentioned by Jason). So all the list manipulations will apply here. This is called "List Slicing". For more info visit here.

The syntax is like this : list[start:end:step]. If you omit start, it will default to 0, and if you omit end, it will default to length of list.

Suppose you only want to take all the arguments after 3rd argument, then :

user_args = sys.argv[3:]

Suppose you only want the first two arguments, then :

user_args = sys.argv[0:2]  or  user_args = sys.argv[:2]

Suppose you want arguments 2 to 4 :

user_args = sys.argv[2:4]

Suppose you want the last argument (last argument is always -1, so what is happening here is we start the count from back. So start is last, no end, no step) :

user_args = sys.argv[-1]

Suppose you want the second last argument :

user_args = sys.argv[-2]

Suppose you want the last two arguments :

user_args = sys.argv[-2:]

Suppose you want the last two arguments. Here, start is -2, that is second last item and then to the end (denoted by ":") :

user_args = sys.argv[-2:]

Suppose you want the everything except last two arguments. Here, start is 0 (by default), and end is second last item :

user_args = sys.argv[:-2]

Suppose you want the arguments in reverse order :

user_args = sys.argv[::-1]

Hope this helps.

Non-numpy functions like math.abs() or math.log10() don't play nicely with numpy arrays. Just replace the line raising an error with:

m = np.log10(np.abs(x))

Apart from that the np.polyfit() call will not work because it is missing a parameter (and you are not assigning the result for further use anyway).

For Windows 7:

To install Pycrypto in Windows,

Assumed you have data frame as below

df1
     A    B    C    D
4 -1.0 -1.0 -1.0 -1.0
5 -1.0 -1.0 -1.0 -1.0
6 -1.0 -1.0 -1.0 -1.0
6 -1.0 -1.0 -1.0 -1.0

When you would like create another df2 which is identical to df1, without copy

df2=df1
df2
     A    B    C    D
4 -1.0 -1.0 -1.0 -1.0
5 -1.0 -1.0 -1.0 -1.0
6 -1.0 -1.0 -1.0 -1.0
6 -1.0 -1.0 -1.0 -1.0

And would like modify the df2 value only as below

df2.iloc[0,0]='changed'

df2
         A    B    C    D
4  changed -1.0 -1.0 -1.0
5       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0

At the same time the df1 is changed as well

df1
         A    B    C    D
4  changed -1.0 -1.0 -1.0
5       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0

Since two df as same object, we can check it by using the id

id(df1)
140367679979600
id(df2)
140367679979600

So they as same object and one change another one will pass the same value as well.

If we add the copy, and now df1 and df2 are considered as different object, if we do the same change to one of them the other will not change.

df2=df1.copy()
id(df1)
140367679979600
id(df2)
140367674641232

df1.iloc[0,0]='changedback'
df2
         A    B    C    D
4  changed -1.0 -1.0 -1.0
5       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0

Good to mention, when you subset the original dataframe, it is safe to add the copy as well in order to avoid the SettingWithCopyWarning

Oracle optimizer chooses join order of tables for inner join. Optimizer chooses the join order of tables only in simple FROM clauses . U can check the oracle documentation in their website. And for the left, right outer join the most voted answer is right. The optimizer chooses the optimal join order as well as the optimal index for each table. The join order can affect which index is the best choice. The optimizer can choose an index as the access path for a table if it is the inner table, but not if it is the outer table (and there are no further qualifications).

The optimizer chooses the join order of tables only in simple FROM clauses. Most joins using the JOIN keyword are flattened into simple joins, so the optimizer chooses their join order.

The optimizer does not choose the join order for outer joins; it uses the order specified in the statement.

When selecting a join order, the optimizer takes into account: The size of each table The indexes available on each table Whether an index on a table is useful in a particular join order The number of rows and pages to be scanned for each table in each join order

I had this problem in a fledgling Express API project.

The offending server code in src/server/server.js:

import express from 'express';
import {initialDonationItems, initialExpenditureItems} from "./DemoData";

const server = express();

server.get('/api/expenditures', (req, res) => {
  res.type('json');
  res.send(initialExpenditureItems);
});

server.get('/api/donations', (req, res) => {
  res.type('json');
  res.send(initialDonationItems);
});

server.listen(4242, () => console.log('Server is running...'));

Here were my dependencies:

{
  "name": "contributor-api",
  "version": "0.0.1",
  "description": "A Node backend to provide storage services",
  "scripts": {
    "dev-server": "nodemon --exec babel-node src/server/server.js --ignore dist/",
    "test": "jest tests"
  },
  "license": "ISC",
  "dependencies": {
    "@babel/core": "^7.9.6",
    "@babel/node": "^7.8.7",
    "babel-loader": "^8.1.0",
    "express": "^4.17.1",
    "mysql2": "^2.1.0",

  },
  "devDependencies": {
    "jest": "^25.5.4",
    "nodemon": "^2.0.3"
  }
}

And here was the runner that threw the error:

nodemon --exec babel-node src/server/server.js --ignore dist

This was frustrating, as I had a similar Express project that worked fine.

The solution was firstly to add this dependency:

npm install @babel/preset-env

And then to wire it in using a babel.config.js in the project root:

module.exports = {
  presets: ['@babel/preset-env'],
};

I don't fully grok why this works, but I copied it from an authoritative source, so I am happy to stick with it.

What is the difference between them?

Image: the generic Linux kernel binary image file.

zImage: a compressed version of the Linux kernel image that is self-extracting.

uImage: an image file that has a U-Boot wrapper (installed by the mkimage utility) that includes the OS type and loader information.
A very common practice (e.g. the typical Linux kernel Makefile) is to use a zImage file. Since a zImage file is self-extracting (i.e. needs no external decompressors), the wrapper would indicate that this kernel is "not compressed" even though it actually is.

Note that the author/maintainer of U-Boot considers the (widespread) use of using a zImage inside a uImage questionable:

Actually it's pretty stupid to use a zImage inside an uImage. It is much better to use normal (uncompressed) kernel image, compress it using just gzip, and use this as poayload for mkimage. This way U-Boot does the uncompresiong instead of including yet another uncompressor with each kernel image.

(quoted from https://lists.yoctoproject.org/pipermail/yocto/2013-October/016778.html)

Which type of kernel image do I have to use?

You could choose whatever you want to program for.
For economy of storage, you should probably chose a compressed image over the uncompressed one.
Beware that executing the kernel (presumably the Linux kernel) involves more than just loading the kernel image into memory. Depending on the architecture (e.g. ARM) and the Linux kernel version (e.g. with or without DTB), there are registers and memory buffers that may have to be prepared for the kernel. In one instance there was also hardware initialization that U-Boot performed that had to be replicated.

ADDENDUM

I know that u-boot needs a kernel in uImage format.

That is accurate for all versions of U-Boot which only have the bootm command.
But more recent versions of U-Boot could also have the bootz command that can boot a zImage.

struct and typedef are two very different things.

The struct keyword is used to define, or to refer to, a structure type. For example, this:

struct foo {
    int n;
};

creates a new type called struct foo. The name foo is a tag; it's meaningful only when it's immediately preceded by the struct keyword, because tags and other identifiers are in distinct name spaces. (This is similar to, but much more restricted than, the C++ concept of namespaces.)

A typedef, in spite of the name, does not define a new type; it merely creates a new name for an existing type. For example, given:

typedef int my_int;

my_int is a new name for int; my_int and int are exactly the same type. Similarly, given the struct definition above, you can write:

typedef struct foo foo;

The type already has a name, struct foo. The typedef declaration gives the same type a new name, foo.

The syntax allows you to combine a struct and typedef into a single declaration:

typedef struct bar {
    int n;
} bar;

This is a common idiom. Now you can refer to this structure type either as struct bar or just as bar.

Note that the typedef name doesn't become visible until the end of the declaration. If the structure contains a pointer to itself, you have use the struct version to refer to it:

typedef struct node {
    int data;
    struct node *next; /* can't use just "node *next" here */
} node;

Some programmers will use distinct identifiers for the struct tag and for the typedef name. In my opinion, there's no good reason for that; using the same name is perfectly legal and makes it clearer that they're the same type. If you must use different identifiers, at least use a consistent convention:

typedef struct node_s {
    /* ... */
} node;

(Personally, I prefer to omit the typedef and refer to the type as struct bar. The typedef save a little typing, but it hides the fact that it's a structure type. If you want the type to be opaque, this can be a good thing. If client code is going to be referring to the member n by name, then it's not opaque; it's visibly a structure, and in my opinion it makes sense to refer to it as a structure. But plenty of smart programmers disagree with me on this point. Be prepared to read and understand code written either way.)

(C++ has different rules. Given a declaration of struct blah, you can refer to the type as just blah, even without a typedef. Using a typedef might make your C code a little more C++-like -- if you think that's a good thing.)

Since the image is a linux, one thing to check is to make sure any shell scripts used in the container have unix line endings. If they have a ^M at the end then they are windows line endings. One way to fix them is with dos2unix on /usr/local/start-all.sh to convert them from windows to unix. Running the docker in interactive mode can help figure out other problems.

Create a .bash_profile file for your environment variables

• Open the Terminal app
• Go to your home directory via cd ~
• Create the file with touch .bash_profile

Add the PATH variable to your .bash_profile

• Open the file via open .bash_profile

• Add export PATH=$PATH: [your SDK location] /platform-tools to the file and hit ?s to save it. By default it's:

  export PATH=$PATH:/Users/yourUserName/Library/Android/sdk/platform-tools

• Go back to your Terminal App and load the variable with source ~/.bash_profile

If you have installed Java through brew in Mac then chances are you will find your Java Home Directory here:

/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home

The next step now would be to find which Java Home directory maven is pointing to. To find it type in the command:
mvn -version

The fields we are interested in here is: Java version and runtime.

Maven is currently pointing to Java 13. Also, you can see the Java Home path under the key runtime, which is:
/usr/local/Cellar/openjdk/13.0.2+8_2/libexec/openjdk.jdk/Contents/Home

To change the Java version of the maven, we need to add the Java 8 home path to the JAVA_HOME env variable.

To do that we need to run the command:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home in the terminal.

Now if we check the maven version, we can see that it is pointing to Java 8 now.

The problem with this is if you check the maven version again in the new terminal, you will find that it is pointing to the Java 13. To avoid this I would suggest adding the JAVA_HOME variable in the ~/.profile file.

This way whenever your terminal is loading it will take up the value you defined in the JAVA_HOME by default. This is the line you need to add in the ~/.profile file:
export JAVA_HOME=/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home

You can open up a new terminal and check the Maven version, (mvn -version) and you will find it is pointing to the Java 8 this time.

Better to use change event on input field.

Updated source:

var myfile="";

$('#resume_link').click(function( e ) {
    e.preventDefault();
    $('#resume').trigger('click');
});

$('#resume').on( 'change', function() {
   myfile= $( this ).val();
   var ext = myfile.split('.').pop();
   if(ext=="pdf" || ext=="docx" || ext=="doc"){
       alert(ext);
   } else{
       alert(ext);
   }
});

Updated jsFiddle.

Just make sure you don't have any dependencies on the current state in there.

When onMeasure is called the view gets its measured width/height. After this, you can call layout.getMeasuredHeight().

You can access the window object as an associative array and set it that way

window["onlyVideo"] = "TEST";
document.write(onlyVideo);

After git commit command, you entered to the editor, so first hit i then start typing. After committing your message hit Ctrl + c then :wq

This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.

There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.

The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like

1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host

EDIT

Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication

-a and -o are the older and/or operators for the test command. && and || are and/or operators for the shell. So (assuming an old shell) in your first case,

[ "$1" = 'yes' ] && [ -r $2.txt ]

The shell is evaluating the and condition. In your second case,

[ "$1" = 'yes' -a $2 -lt 3 ]

The test command (or builtin test) is evaluating the and condition.

Of course in all modern or semi-modern shells, the test command is built in to the shell, so there really isn't any or much difference. In modern shells, the if statement can be written:

[[ $1 == yes && -r $2.txt ]]

Which is more similar to modern programming languages and thus is more readable.

Works for me too, here is a better solution::

fiddle demo

<form id="myForm">
  <input type="radio" name="radioName" value="1" />one<br />
  <input type="radio" name="radioName" value="2" />two 
</form>

<script>
$('#myForm input[type=radio]').change(function() {       
    alert(this.value);
});
</script>

You must make sure that you initialized jquery above all other imports and javascript functions. Because $ is a jquery function. Even

$(function(){
 <code>
}); 

will not check jquery initialised or not. It will ensure that <code> will run only after all the javascripts are initialized.

Use the DO statement, a new option in version 9.0:

DO LANGUAGE plpgsql
$$
BEGIN
CREATE TABLE "Logs"."Events"
    (
        EventId BIGSERIAL NOT NULL PRIMARY KEY,
        PrimaryKeyId bigint NOT NULL,
        EventDateTime date NOT NULL DEFAULT(now()),
        Action varchar(12) NOT NULL,
        UserId integer NOT NULL REFERENCES "Office"."Users"(UserId),
        PrincipalUserId varchar(50) NOT NULL DEFAULT(user)
    );

    CREATE TABLE "Logs"."EventDetails"
    (
        EventDetailId BIGSERIAL NOT NULL PRIMARY KEY,
        EventId bigint NOT NULL REFERENCES "Logs"."Events"(EventId),
        Resource varchar(64) NOT NULL,
        OldVal varchar(4000) NOT NULL,
        NewVal varchar(4000) NOT NULL
    );

    RAISE NOTICE 'Task completed sucessfully.';    
END;
$$;

You can use StreamReader.ReadToEnd(),

using (Stream stream = response.GetResponseStream())
{
   StreamReader reader = new StreamReader(stream, Encoding.UTF8);
   String responseString = reader.ReadToEnd();
}

Try add !important to your css. Its working for me.

.panel {
  float: right;
  width: 120px;
  height: auto;
  background: #fff;
  border-radius: 7px!important;
}

This feature is in pre-release now and works with Visual Studio 2015.

For example:

[TestClass]
public class UnitTest1
{
    [TestMethod]
    [DataRow(1, 2, 2)]
    [DataRow(2, 3, 5)]
    [DataRow(3, 5, 8)]
    public void AdditionTest(int a, int b, int result)
    {
        Assert.AreEqual(result, a + b);
    }
}

Maybe using pytest_collect_file() hook you can parse the content of a .txt o .yaml file where the tests are specify as you want, and return them to the pytest core.

A nice example is shown in the pytest documentation. I think what you are looking for.

To modify the results under pivot, you can put the columns in the selected fields and then modify them accordingly. May be you can use DECODE for the columns you have built using pivot function.

Is there a way to do this?

If npm libraries can be used as a solution, object-merge-advanced from yours truly allows to merge objects deeply and customise/override every single merge action using a familiar callback function. The main idea of it is more than just deep merging — what happens with the value when two keys are the same? This library takes care of that — when two keys clash, object-merge-advanced weighs the types, aiming to retain as much data as possible after merging:

First input argument's key is marked #1, second argument's — #2. Depending on each type, one is chosen for the result key's value. In diagram, "an object" means a plain object (not array etc).

When keys don't clash, they all enter the result.

From your example snippet, if you used object-merge-advanced to merge your code snippet:

const mergeObj = require("object-merge-advanced");
const x = { a: { a: 1 } };
const y = { a: { b: 1 } };
const res = console.log(mergeObj(x, y));
// => res = {
//      a: {
//        a: 1,
//        b: 1
//      }
//    }

It's algorithm recursively traverses all input object keys, compares and builds and returns the new merged result.

The short answer to 2nd part of the question is simply that CString class doesn't provide a direct typecast conversion by design and what you are doing is kind of cheat.

A longer answer is the following:

The reason you can typcast CString to LPCTSTR is because CString provides this facility by overriding operator=. By design it provides conversion to only LPCTSTR pointer so the string value can't be modified with this pointer.

In other words, it simply doesn't provide an overload operator= to convert the CString into LPSTR for the same reason as above. They don't want to allow altering the string value this way.

So essentially, the trick is to use the operator CString provide and get this:

LPTSTR lptstr = (LPCTSTR) string; // CString provide this operator overload

Now LPTSTR can be further type casted to LPSTR :)

dispinfo.item.pszText = LPTSTR( lpfzfd); // accomplish the cheat :P

The correct way to get LPTSTR from 'CString' is this though (complete example):

CString str = _T("Hello");
LPTSTR lpstr = str.GetBuffer(str.GetAllocLength());
str.ReleaseBuffer(); // you must call this function if you change the string above with the pointer

Again because the GetBuffer() returns LPTSTR for that reason that now you can modify :)

You could use str.split to do this.

s = "<alpha.Customer[cus_Y4o9qMEZAugtnW] active_card=<alpha.AlphaObject[card]\
 ...>, created=1324336085, description='Customer for My Test App',\
 livemode=False>"
val = s.split('[', 1)[1].split(']')[0]

Then we have:

>>> val
'cus_Y4o9qMEZAugtnW'

1. Download cURL (Win64 ia64 zip binary with SSL)
2. Extract curl.exe into "C:\Windows\System32"
3. Done

Even more easier:

Download the Win64 2000/XP x86_64 MSI installer provided by Edward LoPinto.

At the time of writing file curl-7.46.0-win64.exe was the most recent. Tested with Windows 10.

It is session-based, when set the way you did in your question.

https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html

According to this, FOREIGN_KEY_CHECKS is "Both" for scope. This means it can be set for session:

SET FOREIGN_KEY_CHECKS=0;

or globally:

SET GLOBAL FOREIGN_KEY_CHECKS=0;

If you just want to extract something from existing commit and keep the original one, you can use

git reset --patch HEAD^

instead of git reset HEAD^. This command allows you to reset just chunks you need.

After you chose the chunks you want to reset, you'll have staged chunks that will reset changes in previous commit after you do

git commit --amend --no-edit

and unstaged chunks that you can add to the separate commit by

git add .
git commit -m "new commit"

Off topic fact:

In mercurial they have hg split - the second feature after hg absorb I'd like to see in git.

r = read mode only
r+ = read/write mode
w = write mode only
w+ = read/write mode, if the file already exists override it (empty it)

So yes, if the file already exists w+ will erase the file and give you an empty file.

I am in same situation, I want to merge a file from a branch which has many commits on it on 2 branch. I tried many ways above and other I found on the internet and all failed (because commit history is complex) so I decide to do my way (the crazy way).

git merge <other-branch>
cp file-to-merge file-to-merge.example
git reset --hard HEAD (or HEAD^1 if no conflicts happen)
cp file-to-merge.example file-to-merge

There is a bundled collection of Vim plugins for Python development: http://www.vim.org/scripts/script.php?script_id=3770

According to the official site. These are the two ways

<div>
  {/* Comment goes here */}
  Hello, {name}!
</div>

Second Example:

<div>
    {/* It also works 
    for multi-line comments. */}
    Hello, {name}! 
</div>

As far as I can tell, GitHub does not provide shell access, so I'm curious about how you managed to log in in the first place.

$ ssh -T [email protected]
Hi username! You've successfully authenticated, but GitHub does not provide
shell access.

You have to clone your repository locally, make the change there, and push the change to GitHub.

$ git clone [email protected]:username/reponame.git
$ cd reponame
$ git mv README README.md
$ git commit -m "renamed"
$ git push origin master

Also, search on "javascript base64 encoding" turns a lot of other options, the above was the first one.

Solution posted by Denys S. in the question post:

I quite messed it up with c to c++ conversion (basically env variable stuff), but I got it working with the following code for C++:

#include <string.h>
#include <stdio.h>
#include <jni.h>

jstring Java_the_package_MainActivity_getJniString( JNIEnv* env, jobject obj){

    jstring jstr = (*env)->NewStringUTF(env, "This comes from jni.");
    jclass clazz = (*env)->FindClass(env, "com/inceptix/android/t3d/MainActivity");
    jmethodID messageMe = (*env)->GetMethodID(env, clazz, "messageMe", "(Ljava/lang/String;)Ljava/lang/String;");
    jobject result = (*env)->CallObjectMethod(env, obj, messageMe, jstr);

    const char* str = (*env)->GetStringUTFChars(env,(jstring) result, NULL); // should be released but what a heck, it's a tutorial :)
    printf("%s\n", str);

    return (*env)->NewStringUTF(env, str);
}

And next code for java methods:

    public class MainActivity extends Activity {
    private static String LIB_NAME = "thelib";

    static {
        System.loadLibrary(LIB_NAME);
    }

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        TextView tv = (TextView) findViewById(R.id.textview);
        tv.setText(this.getJniString());
    }

    // please, let me live even though I used this dark programming technique
    public String messageMe(String text) {
        System.out.println(text);
        return text;
    }

    public native String getJniString();
}

I don't think you can. This is because if a variable is undefined (not set) in the twig template, it looks like NULL or none (in twig terms). I'm pretty sure this is to suppress bad access errors from occurring in the template.

Due to the lack of a "identity" in Twig (===) this is the best you can do

{% if var == null %}
    stuff in here
{% endif %}

Which translates to:

if ((isset($context['somethingnull']) ? $context['somethingnull'] : null) == null)
{
  echo "stuff in here";
}

Which if your good at your type juggling, means that things such as 0, '', FALSE, NULL, and an undefined var will also make that statement true.

My suggest is to ask for the identity to be implemented into Twig.

Protocol Buffers seems to have a more compact representation, but that's only an impression I get from reading the Thrift whitepaper. In their own words:

We decided against some extreme storage optimizations (i.e. packing small integers into ASCII or using a 7-bit continuation format) for the sake of simplicity and clarity in the code. These alterations can easily be made if and when we encounter a performance-critical use case that demands them.

Also, it may just be my impression, but Protocol Buffers seems to have some thicker abstractions around struct versioning. Thrift does have some versioning support, but it takes a bit of effort to make it happen.

If you accidentally reset your keychain, this can occur due to missing Apple certificates in the keychain. I followed this to solve my problem.

I had the same issue and was able to fix by re-downloading the WWDR (Apple Worldwide Developer Relations Certification Authority). Download from here: http://developer.apple.com/certificationauthority/AppleWWDRCA.cer

<script>
function checkusers()
{
   var shouldEnable = document.getElementById('checkbox').value == 0;
   document.getElementById('add_button').disabled = shouldEnable;
}
</script>

You may want to use:

SELECT Name, 'Unpaid' AS Status FROM table;

The SELECT clause syntax, as defined in MSDN: SELECT Clause (Transact-SQL), is as follows:

SELECT [ ALL | DISTINCT ]
[ TOP ( expression ) [ PERCENT ] [ WITH TIES ] ] 
<select_list> 

Where the expression can be a constant, function, any combination of column names, constants, and functions connected by an operator or operators, or a subquery.

It looks like the one-liner got even simpler along the line (currently using R 3.5.3):

# generate original data.frame
df <- data.frame(a = letters[1:10], b = 1:10, c = LETTERS[1:10])
# use first column for row names
df <- data.frame(df, row.names = 1)

The column used for row names is removed automatically.

Make sure that you aren't still in the mounted device when you are trying to umount.

Or you can use this:

^(?:part[12]|(part)1,\12)$

Can't tell how long it would take, it really depends on your existing knowlege. I managed to learn the C#/.NET 2.0 core basics in about 2 months. My suggestion to you: Try to learn towards exams, they make sure your learning covers all important parts and also guide you through this new technology. See Microsoft Learning.

Although not part of Django, Airflow is a more recent project (as of 2016) that is useful for task management.

Airflow is a workflow automation and scheduling system that can be used to author and manage data pipelines. A web-based UI provides the developer with a range of options for managing and viewing these pipelines.

Airflow is written in Python and is built using Flask.

Airflow was created by Maxime Beauchemin at Airbnb and open sourced in the spring of 2015. It joined the Apache Software Foundation’s incubation program in the winter of 2016. Here is the Git project page and some addition background information.

To correct this mistake very easily, If you read logs. The problem occurs because of the sudden shutdown of the IDEA. And the log files do not correctly write data. Just delete the file on the path

C:/Users/{UserName}/.Gradle/demon/{gradleVersion}/registry.bin.lock. 

Try the following:

select distinct city 
from station 
where city like '%[aeuio]'and city like '[aeuio]%' Order by City;

You found the way: create a function instead of an alias. The C shell has a mechanism for doing arguments to aliases, but bash and the Korn shell don't, because the function mechanism is more flexible and offers the same capability.

I solved it in my site making this in functions.php

add_action("template_redirect", "start_buffer");
add_action("shutdown", "end_buffer", 999);

function filter_buffer($buffer) {
    $buffer = replace_insecure_links($buffer);
    return $buffer;
}
function start_buffer(){
    ob_start("filter_buffer");
}

function end_buffer(){
    if (ob_get_length()) ob_end_flush();
}

function replace_insecure_links($str) {

   $str = str_replace ( array("http://www.yoursite.com/", "https://www.yoursite.com/") , array("/", "/"), $str);

   return apply_filters("rsssl_fixer_output", $str);

}

I took part of one plugin, cut it into pieces and make this. It replaced ALL links in my site (menus, css, scripts etc.) and everything was working.

As far as I'm aware this is the only answer here that works correctly with spaces:

space:= 
space+=

CURRENT_PATH := $(subst $(lastword $(notdir $(MAKEFILE_LIST))),,$(subst $(space),\$(space),$(shell realpath '$(strip $(MAKEFILE_LIST))')))

It essentially works by escaping space characters by substituting ' ' for '\ ' which allows Make to parse it correctly, and then it removes the filename of the makefile in MAKEFILE_LIST by doing another substitution so you're left with the directory that makefile is in. Not exactly the most compact thing in the world but it does work.

You'll end up with something like this where all the spaces are escaped:

$(info CURRENT_PATH = $(CURRENT_PATH))

CURRENT_PATH = /mnt/c/Users/foobar/gDrive/P\ roje\ cts/we\ b/sitecompiler/

just use bash

while read -r line
do
  case "$line" in
    *MYSQL_ROLE=master*)
       echo "do your stuff";;
    *) echo "doesn't exist";;      
  esac
done <"/etc/aws/hosts.conf"

$foo = array('a' => 'apple', 'b' => 'ball', 'c' => 'coke');

foreach($foo as $key => $item) {
  echo $item.' is begin with ('.$key.')';
}

Another crazy solution is (without converting in a string):

number = 123.456
temp = 1

while (number*temp)%10 != 0:
    temp = temp *10
    print temp
    print number

temp = temp /10
number = number*temp
number_final = number%temp
print number_final

As mentioned in one of the other answers, you can use putc(int c, FILE *stream), putchar(int c) or fputc(int c, FILE *stream) for this purpose.

What's important to note is that using any of the above functions is from some to signicantly faster than using any of the format-parsing functions like printf.

Using printf is like using a machine gun to fire one bullet.

MySQL documentation covers this topic.

Here is a synopsis. When using join or inner join, the on condition is optional. This is different from the ANSI standard and different from almost any other database. The effect is a cross join. Similarly, you can use an on clause with cross join, which also differs from standard SQL.

A cross join creates a Cartesian product -- that is, every possible combination of 1 row from the first table and 1 row from the second. The cross join for a table with three rows ('a', 'b', and 'c') and a table with four rows (say 1, 2, 3, 4) would have 12 rows.

In practice, if you want to do a cross join, then use cross join:

from A cross join B

is much better than:

from A, B

and:

from A join B -- with no on clause

The on clause is required for a right or left outer join, so the discussion is not relevant for them.

If you need to understand the different types of joins, then you need to do some studying on relational databases. Stackoverflow is not an appropriate place for that level of discussion.

The above answer is already satisfying the topic. Anyway, if you need all the data in memory - have a look at bcolz. Its compressing the data in memory. I have had really good experience with it. But its missing a lot of pandas features

Edit: I got compression rates at around 1/10 or orig size i think, of course depending of the kind of data. Important features missing were aggregates.

You are most probably missing a file called rt.jar in your installation which has the class file for java.lang.Object. Check your install files etc.

In particular, note that a 64-bit intsaller overlays (or installs "next to") an existing 32-bit installation. In other words, to get a fully working 64-bit installation, you must first run the 32-bit installation, and follow that up with a 64-bit installation if you have a 64bit capable machine...

If instead you do just a 64-bit installation you will be missing certain files in the installation and will get errors such as the one above.

wget -r http://mysite.com/configs/.vim/

works for me.

Perhaps you have a .wgetrc which is interfering with it?

My suggestion:

using System.Linq;

string myStringOutput = String.Join(",", myArray.Select(p => p.ToString()).ToArray());

Though @Test(expected = MyException.class) and the ExpectedException rule are very good choices, there are some instances where the JUnit3-style exception catching is still the best way to go:

@Test public void yourTest() {
  try {
    systemUnderTest.doStuff();
    fail("MyException expected.");
  } catch (MyException expected) {

    // Though the ExpectedException rule lets you write matchers about
    // exceptions, it is sometimes useful to inspect the object directly.

    assertEquals(1301, expected.getMyErrorCode());
  }

  // In both @Test(expected=...) and ExpectedException code, the
  // exception-throwing line will be the last executed line, because Java will
  // still traverse the call stack until it reaches a try block--which will be
  // inside the JUnit framework in those cases. The only way to prevent this
  // behavior is to use your own try block.

  // This is especially useful to test the state of the system after the
  // exception is caught.

  assertTrue(systemUnderTest.isInErrorState());
}

Another library that claims to help here is catch-exception; however, as of May 2014, the project appears to be in maintenance mode (obsoleted by Java 8), and much like Mockito catch-exception can only manipulate non-final methods.

or is not exclusive (e.g. xor) so or is the same thing as and/or.

For your input data:

let widthRange = new Array()
widthRange[46] = { min:0,  max:52 }
widthRange[61] = { min:52, max:70 }
widthRange[62] = { min:52, max:70 }
widthRange[63] = { min:52, max:70 }
widthRange[66] = { min:52, max:70 }
widthRange[90] = { min:70, max:94 }

Declarative approach:

const relevantKeys = [46,66,90]
const relevantValues = Object.keys(widthRange)
    .filter(index => relevantKeys.includes(parseInt(index)))
    .map(relevantIndex => widthRange[relevantIndex])

Object.keys to get the keys, using parseInt to cast them as numbers. filter to get only ones you want. map to build an array from the original object of just the indices you're after, since Object.keys loses the object values.

Debug:

console.log(widthRange)
console.log(relevantKeys)
console.log(relevantValues)

I had the same issue with my Android development using Android studio. Solutions provided are general and did not help me ( at least for me). After hours of research I found following solution and may help to android developers who are doing development using android studio. modify the setting as below Preferences ->Build, Execution, Deployment -> Instant Run -> un-check the first option.

With this change I am up and running. Hope this will help my dev friends.

In my case it was solved by doing this:

Go to your 'Runtime Configuration' and configure your JRE to an JDK.

I copied answer just in case it is deleted for some reason, but the source is here

You can use JSONPath

Doing something like this:

results = JSONPath(null, TestObj, "$..[?(@.id=='A')]")

Note that JSONPath returns an array of results

(I have not tested the expression "$..[?(@.id=='A')]" btw. Maybe it needs to be fine-tuned with the help of a browser console)

I'd do it like this jsFiddle example.

JavaScript:

function check(elem) {
    document.getElementById('mySelect1').disabled = !elem.selectedIndex;
}

HTML:

<form>
<select id="mySelect" onChange="check(this);">
<option>No</option>
<option>Yes</option>
</select>

<select id="mySelect1" disabled="disabled" >
<option>Dep1</option>
<option>Dep2</option>
<option>Dep3</option>
<option>Dep4</option>
</select>
</form>

You can use livequery plugin for jQuery. You can provide a selector expression such as:

$("input[type=button].removeItemButton").livequery(function () {
    $("#statusBar").text('You may now remove items.');
});

Every time a button of a removeItemButton class is added a message appears in a status bar.

In terms of efficiency you might want avoid this, but in any case you could leverage the plugin instead of creating your own event handlers.

Revisited answer

The answer above was only meant to detect that an item has been added to the DOM through the plugin.

However, most likely, a jQuery.on() approach would be more appropriate, for example:

$("#myParentContainer").on('click', '.removeItemButton', function(){
          alert($(this).text() + ' has been removed');
});

If you have dynamic content that should respond to clicks for example, it's best to bind events to a parent container using jQuery.on.

For PyCharm 2017

We can follow below: File >> Settings >> Editor >> Code Style.

Then provide values for Hard Wrap & Visual Guides for wrapping while typing, tick the checkbox.

NB: look at other tabs as well, viz. Python, HTML, JSON etc.

It may be late to answer this question but I hope to document 2 good features from Pandas: pandas.Series.str.split() with regular expression and pandas.Series.explode().

import pandas as pd
import numpy as np

df = pd.DataFrame(
    {'CustNum': [32363, 31316],
     'CustomerName': ['McCartney, Paul', 'Lennon, John'],
     'ItemQty': [3, 25],
     'Item': ['F04', 'F01'],
     'Seatblocks': ['2:218:10:4,6', '1:13:36:1,12 1:13:37:1,13'],
     'ItemExt': [60, 360]
    }
)

print(df)
print('-'*80+'\n')

df['Seatblocks'] = df['Seatblocks'].str.split('[ :]')
df = df.explode('Seatblocks').reset_index(drop=True)
cols = list(df.columns)
cols.append(cols.pop(cols.index('CustomerName')))
df = df[cols]


print(df)
print('='*80+'\n')
print(df[df['CustomerName'] == 'Lennon, John'])

The output is:

   CustNum     CustomerName  ItemQty Item                 Seatblocks  ItemExt

You also have the shortcut option of

Dir["/path/to/search/*"]

and if you want to find all Ruby files in any folder or sub-folder:

Dir["/path/to/search/**/*.rb"]

You can solve it in these steps

1. Right-click on the project in the left toolbar.
2. Click on properties.
3. Click on Run
4. Click the browse button on the right side.(select your main class)
5. Click ok

Try this:

public void LoadData()
        {
            SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=Stocks;Integrated Security=True;Pooling=False");
            SqlDataAdapter sda = new SqlDataAdapter("Select * From [Stocks].[dbo].[product]", con);
            DataTable dt = new DataTable();
            sda.Fill(dt);
            DataGridView1.Rows.Clear();

        foreach (DataRow item in dt.Rows)
        {
            int n = DataGridView1.Rows.Add();
            DataGridView1.Rows[n].Cells[0].Value = item["ProductCode"].ToString();
            DataGridView1.Rows[n].Cells[1].Value = item["Productname"].ToString();
            DataGridView1.Rows[n].Cells[2].Value = item["qty"].ToString();                
            if ((bool)item["productstatus"])
            {
                DataGridView1.Rows[n].Cells[3].Value = "Active";
            }
            else
            {
                DataGridView1.Rows[n].Cells[3].Value = "Deactive";
            }

You could use Reflection to get the value of the property.

list = list.OrderBy( x => TypeHelper.GetPropertyValue( x, sortBy ) )
           .ToList();

Where TypeHelper has a static method like:

public static class TypeHelper
{
    public static object GetPropertyValue( object obj, string name )
    {
        return obj == null ? null : obj.GetType()
                                       .GetProperty( name )
                                       .GetValue( obj, null );
    }
}

You might also want to look at Dynamic LINQ from the VS2008 Samples library. You could use the IEnumerable extension to cast the List as an IQueryable and then use the Dynamic link OrderBy extension.

 list = list.AsQueryable().OrderBy( sortBy + " " + sortDirection );

For nestjs users, the simple alternative is to use,

npm test -t <name of the spec file to run>

Nestjs comes preconfigured with the regex of the test files to search for incase of jest A simple example is -

npm test -t app-util.spec.ts

(that is my spec file name)

The complete path need not be given since jest searches for spec files based on the confuguration which is available by default incase of nestjs

"jest": {
    "moduleFileExtensions": [
      "js",
      "json",
      "ts"
    ],
    "rootDir": "src",
    "testRegex": ".spec.ts$",
    "transform": {
      "^.+\\.(t|j)s$": "ts-jest"
    },
    "coverageDirectory": "../coverage",
    "testEnvironment": "node"
  }
}

You can use mysql_errno() for this too.

$result = mysql_query($query);

if(mysql_errno()){
    echo "MySQL error ".mysql_errno().": "
         .mysql_error()."\n<br>When executing <br>\n$query\n<br>";
}

Basically you can't access variables from parent directly. You do this by events. Component's output property is responsible for this. I would suggest reading https://angular.io/docs/ts/latest/guide/template-syntax.html#input-and-output-properties

What you should also do when you truncate the string to ten characters is add the actual html ellipses entity: …, rather than three periods.

if you already have the desired table on your database, first delete it and then run the command below:

 mysql -u username -p  databasename  < yourtable.sql

On newer versions of Symfony2 (using a parameters.yml instead of parameters.ini), you can store objects or arrays instead of key-value pairs, so you can manage your globals this way:

config.yml (edited only once):

# app/config/config.yml
twig:
  globals:
    project: %project%

parameters.yml:

# app/config/parameters.yml
project:
  name:       myproject.com
  version:    1.1.42

And then in a twig file, you can use {{ project.version }} or {{ project.name }}.

Note: I personally dislike adding things to app, just because that's the Symfony's variable and I don't know what will be stored there in the future.

The standard approach is to give the centered element fixed dimensions, and place it absolutely:

<div class='fullscreenDiv'>
    <div class="center">Hello World</div>
</div>?

.center {
    position: absolute;
    width: 100px;
    height: 50px;
    top: 50%;
    left: 50%;
    margin-left: -50px; /* margin is -0.5 * dimension */
    margin-top: -25px; 
}?
