Some good solutions on here!

Here's my version.

• It's strongly typed
• It works with IDE auto-completion
• Enums are defined by a code and a description, where the code can be an integer, a binary value, a short string, or basically anything else you want. The pattern could easily be extended to support orther properties.
• It asupports value (==) and reference (===) comparisons and works in switch statements.

I think the main disadvantage is that enum members do have to be separately declared and instantiated, due to the descriptions and PHP's inability to construct objects at static member declaration time. I guess a way round this might be to use reflection with parsed doc comments instead.

The abstract enum looks like this:

<?php

abstract class AbstractEnum
{
    /** @var array cache of all enum instances by class name and integer value */
    private static $allEnumMembers = array();

    /** @var mixed */
    private $code;

    /** @var string */
    private $description;

    /**
     * Return an enum instance of the concrete type on which this static method is called, assuming an instance
     * exists for the passed in value.  Otherwise an exception is thrown.
     *
     * @param $code
     * @return AbstractEnum
     * @throws Exception
     */
    public static function getByCode($code)
    {
        $concreteMembers = &self::getConcreteMembers();

        if (array_key_exists($code, $concreteMembers)) {
            return $concreteMembers[$code];
        }

        throw new Exception("Value '$code' does not exist for enum '".get_called_class()."'");
    }

    public static function getAllMembers()
    {
        return self::getConcreteMembers();
    }

    /**
     * Create, cache and return an instance of the concrete enum type for the supplied primitive value.
     *
     * @param mixed $code code to uniquely identify this enum
     * @param string $description
     * @throws Exception
     * @return AbstractEnum
     */
    protected static function enum($code, $description)
    {
        $concreteMembers = &self::getConcreteMembers();

        if (array_key_exists($code, $concreteMembers)) {
            throw new Exception("Value '$code' has already been added to enum '".get_called_class()."'");
        }

        $concreteMembers[$code] = $concreteEnumInstance = new static($code, $description);

        return $concreteEnumInstance;
    }

    /**
     * @return AbstractEnum[]
     */
    private static function &getConcreteMembers() {
        $thisClassName = get_called_class();

        if (!array_key_exists($thisClassName, self::$allEnumMembers)) {
            $concreteMembers = array();
            self::$allEnumMembers[$thisClassName] = $concreteMembers;
        }

        return self::$allEnumMembers[$thisClassName];
    }

    private function __construct($code, $description)
    {
        $this->code = $code;
        $this->description = $description;
    }

    public function getCode()
    {
        return $this->code;
    }

    public function getDescription()
    {
        return $this->description;
    }
}

Here's an example concrete enum:

<?php

require('AbstractEnum.php');

class EMyEnum extends AbstractEnum
{
    /** @var EMyEnum */
    public static $MY_FIRST_VALUE;
    /** @var EMyEnum */
    public static $MY_SECOND_VALUE;
    /** @var EMyEnum */
    public static $MY_THIRD_VALUE;

    public static function _init()
    {
        self::$MY_FIRST_VALUE = self::enum(1, 'My first value');
        self::$MY_SECOND_VALUE = self::enum(2, 'My second value');
        self::$MY_THIRD_VALUE = self::enum(3, 'My third value');
    }
}

EMyEnum::_init();

Which can be used like this:

<?php

require('EMyEnum.php');

echo EMyEnum::$MY_FIRST_VALUE->getCode().' : '.EMyEnum::$MY_FIRST_VALUE->getDescription().PHP_EOL.PHP_EOL;

var_dump(EMyEnum::getAllMembers());

echo PHP_EOL.EMyEnum::getByCode(2)->getDescription().PHP_EOL;

And produces this output:

1 : My first value

array(3) {  
  [1]=>  
  object(EMyEnum)#1 (2) {  
    ["code":"AbstractEnum":private]=>  
    int(1)  
    ["description":"AbstractEnum":private]=>  
    string(14) "My first value"  
  }  
  [2]=>  
  object(EMyEnum)#2 (2) {  
    ["code":"AbstractEnum":private]=>  
    int(2)  
    ["description":"AbstractEnum":private]=>  
    string(15) "My second value"  
  }  
  [3]=>  
  object(EMyEnum)#3 (2) {  
    ["code":"AbstractEnum":private]=>  
    int(3)  
    ["description":"AbstractEnum":private]=>  
    string(14) "My third value"  
  }  
}

My second value

if you are using express framework to node.js

install npm ejs

then add config file

app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router)

;

render the page from exports module form.js have the html file in the views dir with extension of ejs file name as form.html.ejs

then create the form.js

res.render('form.html.ejs');

I tried the code provided above, but it gave an error 9 for me. I made this code, and it worked fine for my purposes. I hope others find it useful as well.

Function mergeArrays(ByRef arr1() As Variant, arr2() As Variant) As Variant

    Dim returnThis() As Variant
    Dim len1 As Integer, len2 As Integer, lenRe As Integer, counter As Integer
    len1 = UBound(arr1)
    len2 = UBound(arr2)
    lenRe = len1 + len2
    ReDim returnThis(1 To lenRe)
    counter = 1

    Do While counter <= len1 'get first array in returnThis
        returnThis(counter) = arr1(counter)
        counter = counter + 1
    Loop
    Do While counter <= lenRe 'get the second array in returnThis
        returnThis(counter) = arr2(counter - len1)
        counter = counter + 1
    Loop

mergeArrays = returnThis
End Function

final ListView lv = (ListView) findViewById(R.id.ListView01);

lv.setOnItemClickListener(new OnItemClickListener() {
      public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) {
        String selectedFromList =(String) (lv.getItemAtPosition(myItemInt));

      }                 
});

I hope this fixes your problem.

I am assuming Linux experience in my answer; I found that there are three prerequisites to getting pip install scipy to proceed nicely.

Go here: Installing SciPY

Follow the instructions to download, build and export the env variable for BLAS and then LAPACK. Be careful to not just blindly cut'n'paste the shell commands - there will be a few lines you need to select depending on your architecture, etc., and you'll need to fix/add the correct directories that it incorrectly assumes as well.

The third thing you may need is to yum install numpy-f2py or the equivalent.

Oh, yes and lastly, you may need to yum install gcc-gfortran as the libraries above are Fortran source.

From http://codecorner.galanter.net/2012/06/04/solution-for-operation-is-not-valid-due-to-the-current-state-of-the-object-error/

Issue happens because Microsoft Security Update MS11-100 limits number of keys in Forms collection during HTTP POST request. To alleviate this problem you need to increase that number.

This can be done in your application Web.Config in the <appSettings> section (create the section directly under <configuration> if it doesn’t exist). Add 2 lines similar to the lines below to the section:

<add key="aspnet:MaxHttpCollectionKeys" value="2000" />
<add key="aspnet:MaxJsonDeserializerMembers" value="2000" />

The above example set the limit to 2000 keys. This will lift the limitation and the error should go away.

try the class-name

Query query = session.createQuery("from Employee");

instead of the table name

Query query = session.createQuery("from EMPLOYEE");

This is how I baseically think of the problem.

my.df <- data.frame(group = rep(c(1,2), each = 3), 
        score = runif(6), info = letters[1:6])
my.agg <- with(my.df, aggregate(score, list(group), max))
my.df.split <- with(my.df, split(x = my.df, f = group))
my.agg$info <- unlist(lapply(my.df.split, FUN = function(x) {
            x[which(x$score == max(x$score)), "info"]
        }))

> my.agg
  Group.1         x info
1       1 0.9344336    a
2       2 0.7699763    e

If you don't know there exist any data in your table or not, you can use following query:

SELECT cons_value FROM table_name;

For an Example:

SELECT 1 FROM employee;

1. It will return a column which contains the total number of rows & all rows have the same constant value 1 (for this time it returns 1 for all rows);
2. If there is no row in your table it will return nothing.

So, we use this SQL query to know if there is any data in the table & the number of rows indicates how many rows exist in this table.

You could use a map function that allows multiple arguments, as does the fork of multiprocessing found in pathos.

>>> from pathos.multiprocessing import ProcessingPool as Pool
>>> 
>>> def add_and_subtract(x,y):
...   return x+y, x-y
... 
>>> res = Pool().map(add_and_subtract, range(0,20,2), range(-5,5,1))
>>> res
[(-5, 5), (-2, 6), (1, 7), (4, 8), (7, 9), (10, 10), (13, 11), (16, 12), (19, 13), (22, 14)]
>>> Pool().map(add_and_subtract, *zip(*res))
[(0, -10), (4, -8), (8, -6), (12, -4), (16, -2), (20, 0), (24, 2), (28, 4), (32, 6), (36, 8)]

pathos enables you to easily nest hierarchical parallel maps with multiple inputs, so we can extend our example to demonstrate that.

>>> from pathos.multiprocessing import ThreadingPool as TPool
>>> 
>>> res = TPool().amap(add_and_subtract, *zip(*Pool().map(add_and_subtract, range(0,20,2), range(-5,5,1))))
>>> res.get()
[(0, -10), (4, -8), (8, -6), (12, -4), (16, -2), (20, 0), (24, 2), (28, 4), (32, 6), (36, 8)]

Even more fun, is to build a nested function that we can pass into the Pool. This is possible because pathos uses dill, which can serialize almost anything in python.

>>> def build_fun_things(f, g):
...   def do_fun_things(x, y):
...     return f(x,y), g(x,y)
...   return do_fun_things
... 
>>> def add(x,y):
...   return x+y
... 
>>> def sub(x,y):
...   return x-y
... 
>>> neato = build_fun_things(add, sub)
>>> 
>>> res = TPool().imap(neato, *zip(*Pool().map(neato, range(0,20,2), range(-5,5,1))))
>>> list(res)
[(0, -10), (4, -8), (8, -6), (12, -4), (16, -2), (20, 0), (24, 2), (28, 4), (32, 6), (36, 8)]

If you are not able to go outside of the standard library, however, you will have to do this another way. Your best bet in that case is to use multiprocessing.starmap as seen here: Python multiprocessing pool.map for multiple arguments (noted by @Roberto in the comments on the OP's post)

It looks like your longs are seconds, and not milliseconds. Date constructor takes time as millis, so

Date d = new Date(timeInSeconds * 1000);

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

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

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

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

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

My bible for JPA work is the Java Persistence wikibook. It has a section on unidirectional OneToMany which explains how to do this with a @JoinColumn annotation. In your case, i think you would want:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE")
private Set<Text> text;

I've used a Set rather than a List, because the data itself is not ordered.

The above is using a defaulted referencedColumnName, unlike the example in the wikibook. If that doesn't work, try an explicit one:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE", referencedColumnName="DATREG_META_CODE")
private Set<Text> text;

tblless in the Tabulator package wraps the unix column command, and also aligns numeric columns.

Apart from the suggestions from @arcain I had to add the following Windows Azure Content Delivery Network url to our proxy server's the white-list:

.msecnd.net

You can achieve your goal by ViewModel and Live Data which is cleared by Arnav Rao. Now I put an example to clear it more neatly.

First, the assumed ViewModel is named SharedViewModel.java.

public class SharedViewModel extends ViewModel {
    private final MutableLiveData<Item> selected = new MutableLiveData<Item>();

    public void select(Item item) {
        selected.setValue(item);
    }
    public LiveData<Item> getSelected() {
        return selected;
    }
}

Then the source fragment is the MasterFragment.java from where we want to send a data.

public class MasterFragment extends Fragment {
    private SharedViewModel model;

    public void onViewCreated(@NonNull View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        model = new ViewModelProvider(requireActivity()).get(SharedViewModel.class);
        itemSelector.setOnClickListener(item -> {

            // Data is sent

            model.select(item);
        });
    }
}

And finally the destination fragment is the DetailFragment.java to where we want to receive the data.

public class DetailFragment extends Fragment {

    public void onViewCreated(@NonNull View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        SharedViewModel model = new ViewModelProvider(requireActivity()).get(SharedViewModel.class);
        model.getSelected().observe(getViewLifecycleOwner(), { item ->

           // Data is received 

        });
    }
}

The number of distinct words (i.e. count of entries in the dictionary) can be found using the len() function.

> a = {'foo':42, 'bar':69}
> len(a)
2

To get all the distinct words (i.e. the keys), use the .keys() method.

> list(a.keys())
['foo', 'bar']

If you're looking for some ESP alternatives, you should have a look at Mailjet for Microsoft Azure too! As a global email service and infrastructure provider, they enable you to send, deliver and track transactional and marketing emails via their APIs, SMTP Relay or UI all from one single platform, thought both for developers and emails owners.

This post pertains to R proxy issues on *nix. You should know that R has many libraries/methods to fetch data over internet.

For 'curl', 'libcurl', 'wget' etc, just do the following:

1. Open a terminal. Type the following command:

   sudo gedit /etc/R/Renviron.site
   

2. Enter the following lines:

   http_proxy='http://username:[email protected]:port/'
   https_proxy='https://username:[email protected]:port/'
   

   Replace username, password, abc.com, xyz.com and port with these settings specific to your network.

3. Quit R and launch again.

This should solve your problem with 'libcurl' and 'curl' method. However, I have not tried it with 'httr'. One way to do that with 'httr' only for that session is as follows:

library(httr)
set_config(use_proxy(url="abc.com",port=8080, username="username", password="password"))

You need to substitute settings specific to your n/w in relevant fields.

You need to declare your clients variable as public, e.g.

public string clients;

but you should probably do it as a Property, e.g.

private string clients;
public string Clients{ get{ return clients; } set {clients = value;} }

And then you can call it in your .aspx page like this:

<%=Clients%>

Variables in C# are private by default. Read more on access modifiers in C# on MSDN and properties in C# on MSDN

I understood your problem, change your jdk from your jdk to greaterthan 1.5

I would recommend using the visual designer built into VS2008, as updating the dbml also updates the code that is generated for you. Modifying the dbml outside of the visual designer would result in the underlying code being out of sync.

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

df.shape, where df is your DataFrame.

The problem is WHEN the event is added and EXECUTED via triggering (the document onload property modification can be verified by examining the properties list).

When does this execute and modify onload relative to the onload event trigger:

document.addEventListener('load', ... );

before, during or after the load and/or render of the page's HTML?
This simple scURIple (cut & paste to URL) "works" w/o alerting as naively expected:

data:text/html;charset=utf-8,
    <html content editable><head>
          <script>
                document.addEventListener('load', function(){ alert(42) } );
          </script>
          </head><body>goodbye universe - hello muiltiverse</body>
    </html>

Does loading imply script contents have been executed?

A little out of this world expansion ...
Consider a slight modification:

data:text/html;charset=utf-8,
    <html content editable><head>
          <script>
              if(confirm("expand mind?"))document.addEventListener('load', function(){ alert(42) } );
          </script>
        </head><body>goodbye universe - hello muiltiverse</body>
    </html>

and whether the HTML has been loaded or not.

Rendering is certainly pending since goodbye universe - hello muiltiverse is not seen on screen but, does not the confirm( ... ) have to be already loaded to be executed? ... and so document.addEventListener('load', ... ) ... ?

In other words, can you execute code to check for self-loading when the code itself is not yet loaded?

Or, another way of looking at the situation, if the code is executable and executed then it has ALREADY been loaded as a done deal and to retroactively check when the transition occurred between not yet loaded and loaded is a priori fait accompli.

So which comes first: loading and executing the code or using the code's functionality though not loaded?

onload as a window property works because it is subordinate to the object and not self-referential as in the document case, ie. it's the window's contents, via document, that determine the loaded question err situation.

PS.: When do the following fail to alert(...)? (personally experienced gotcha's):

caveat: unless loading to the same window is really fast ... clobbering is the order of the day
so what is really needed below when using the same named window:

window.open(URIstr1,"w") .
   addEventListener('load', 
      function(){ alert(42); 
         window.open(URIstr2,"w") .
            addEventListener('load', 
               function(){ alert(43); 
                  window.open(URIstr3,"w") .
                     addEventListener('load', 
                        function(){ alert(44); 
                 /*  ...  */
                        } )
               } )
      } ) 

alternatively, proceed each successive window.open with:
alert("press Ok either after # alert shows pending load is done or inspired via divine intervention" );

data:text/html;charset=utf-8,
    <html content editable><head><!-- tagging fluff --><script>

        window.open(
            "data:text/plain, has no DOM or" ,"Window"
         ) . addEventListener('load', function(){ alert(42) } )

        window.open(
            "data:text/plain, has no DOM but" ,"Window"
         ) . addEventListener('load', function(){ alert(4) } )

        window.open(
            "data:text/html,<html><body>has DOM and", "Window"
         ) . addEventListener('load', function(){ alert(2) } )

        window.open(
            "data:text/html,<html><body>has DOM and", "noWindow"
         ) . addEventListener('load', function(){ alert(1) } )

        /* etc. including where body has onload=... in each appropriate open */

    </script><!-- terminating fluff --></head></html>

which emphasize onload differences as a document or window property.

Another caveat concerns preserving XSS, Cross Site Scripting, and SOP, Same Origin Policy rules which may allow loading an HTML URI but not modifying it's content to check for same. If a scURIple is run as a bookmarklet/scriplet from the same origin/site then there maybe success.

ie. From an arbitrary page, this link will do the load but not likely do alert('done'):

    <a href="javascript:window.open('view-source:http://google.ca') . 
                   addEventListener( 'load',  function(){ alert('done') }  )"> src. vu </a>

but if the link is bookmarked and then clicked when viewing a google.ca page, it does both.

test environment:

 window.navigator.userAgent = 
   Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.4) Gecko/2008102920 Firefox/3.0.4 (Splashtop-v1.2.17.0)

This is probably what you wanted:

$('#elem').fadeTo('slow', 0.3, function()
{
    $(this).css('background-image', 'url(' + $img + ')');
}).fadeTo('slow', 1);

With a 1 second delay:

$('#elem').fadeTo('slow', 0.3, function()
{
    $(this).css('background-image', 'url(' + $img + ')');
}).delay(1000).fadeTo('slow', 1);

.onclick should be set to a function instead of a string. Try

elemm.onclick = function() { alert('blah'); };

instead.

You can use .indexOf():

if(str.indexOf(substr) > -1) {

}

Encryption is easy: as others have pointed out, there are classes in the System.Security.Cryptography namespace that do all the work for you. Use them rather than any home-grown solution.

But decryption is easy too. The issue you have is not the encryption algorithm, but protecting access to the key used for decryption.

I would use one of the following solutions:

• DPAPI using the ProtectedData class with CurrentUser scope. This is easy as you don't need to worry about a key. Data can only be decrypted by the same user, so no good for sharing data between users or machines.

• DPAPI using the ProtectedData class with LocalMachine scope. Good for e.g. protecting configuration data on a single secure server. But anyone who can log into the machine can encrypt it, so no good unless the server is secure.

• Any symmetric algorithm. I typically use the static SymmetricAlgorithm.Create() method if I don't care what algorithm is used (in fact it's Rijndael by default). In this case you need to protect your key somehow. E.g. you can obfuscate it in some way and hide it in your code. But be aware that anyone who is smart enough to decompile your code will likely be able to find the key.

You can also specify context location relatively to current classpath, which may be preferable

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:applicationContext*.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

The problem might originate from a macro instruction in SDL_main.h

In that macro your main(){} is renamed to SDL_main(){} because SDL needs its own main(){} on some of the many platforms they support, so they change yours. Mostly it achieves their goal, but on my platform it created problems, rather than solved them. I added a 2nd line in SDL_main.h, and for me all problems were gone.

#define main SDL_main    //Original line. Renames main(){} to SDL_main(){}. 

#define main main        //Added line. Undo the renaming.

If you don't like the compiler warning caused by this pair of lines, comment both lines out.

If your code is in WinApp(){} you don't have this problem at all. This answer only might help if your main code is in main(){} and your platform is similar to mine.

I have: Visual Studio 2019, Windows 10, x64, writing a 32 bit console app that opens windows using SDL2.0 as part of a tutorial.

This?

str = str.replace(/\s/g, '');

Example

var str = '/var/www/site/Brand new document.docx';_x000D_
_x000D_
document.write( str.replace(/\s/g, '') );

Update: Based on this question, this:

str = str.replace(/\s+/g, '');

is a better solution. It produces the same result, but it does it faster.

The Regex

\s is the regex for "whitespace", and g is the "global" flag, meaning match ALL \s (whitespaces).

A great explanation for + can be found here.

As a side note, you could replace the content between the single quotes to anything you want, so you can replace whitespace with any other string.

No, an architect has a different job than a programmer. The architect is more concerned with nonfunctional ("ility") requirements. Like reliability, maintainability, security, and so on. (If you don't agree, consider this thought experiment: compare a CGI program written in C that does a complicated website, versus a Ruby on Rails implementation. They both have the same functional behavior; choosing an RoR architecture has what advantages.)

Generally, a "solution architect" is about the whole system -- hardware, software, and all -- which an "application architect" is working within a fixed platform, but the terms aren't that rigorous or well standardized.

Remove the parentheses:

List<string> nameslist = new List<string> {"one", "two", "three"};

I had problem setting imageView.highlighted = NO; (setting YES worked properly and the image changed to the highlighted one).

The solution was calling [imageView setHighlighted:NO];

Everything worked properly.

There may be two causes:

1. It is case-sensitive: DataFrame .... Dataframe, dataframe will not work.

2. You have not install pandas (pip install pandas) in the python path.

Swift 4

var isModal: Bool {
    return presentingViewController != nil ||
           navigationController?.presentingViewController?.presentedViewController === navigationController ||
           tabBarController?.presentingViewController is UITabBarController
}

You can gtk-server for this. Gtk-server is a program that runs in background and provides text-based interface to allow other programs (including bash scripts) to control it. It has examples for Bash (http://www.gtk-server.org/demo-ipc.bash.txt, http://www.gtk-server.org/demo-fifo.bash.txt)

Shorthand is not preferred for scripts; it is less readable. The %{} operator is considered shorthand. Here's how it should be done in a script for readability and reusability:

Variable Setup

PS> $hash = @{
    a = 1
    b = 2
    c = 3
}
PS> $hash

Name                           Value
----                           -----
c                              3
b                              2
a                              1

Option 1: GetEnumerator()

Note: personal preference; syntax is easier to read

The GetEnumerator() method would be done as shown:

foreach ($h in $hash.GetEnumerator()) {
    Write-Host "$($h.Name): $($h.Value)"
}

Output:

c: 3
b: 2
a: 1

Option 2: Keys

The Keys method would be done as shown:

foreach ($h in $hash.Keys) {
    Write-Host "${h}: $($hash.Item($h))"
}

Output:

c: 3
b: 2
a: 1

Additional information

Be careful sorting your hashtable...

Sort-Object may change it to an array:

PS> $hash.GetType()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     Hashtable                                System.Object


PS> $hash = $hash.GetEnumerator() | Sort-Object Name
PS> $hash.GetType()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     Object[]                                 System.Array

This and other PowerShell looping are available on my blog.

It is a bit of a "brute force" but works ;)

=IF(E4/1000<1;CONCATENATE(E4;" bps");IF(E4/1000<1000;CONCATENATE(ROUND(E4/1000;2);" kbps");IF(E4/1000000<1000;CONCATENATE(ROUND(E4/1000000;2);" mbps");IF(E4/1000000000<1000;CONCATENATE(ROUND(E4/1000000000;2);" gbps")))))

Am I doing something wrong here?

Yes, you are. One servlet container is already running on port 8080 and you are trying to run another one on port 8080 again.

Either restart the server (If there is button for that in STS) or stop and start it

According to the documentation, $lookup can join only one external collection.

What you could do is to combine userInfo and userRole in one collection, as provided example is based on relational DB schema. Mongo is noSQL database - and this require different approach for document management.

Please find below 2-step query, which combines userInfo with userRole - creating new temporary collection used in last query to display combined data. In last query there is an option to use $out and create new collection with merged data for later use.

db.sivaUser.insert(

            "role" :1,
            "email" : "$user.email",
            "userName" : "$user.userName"
        }
    }
])

There are two options:

First

You can also use like is()

$('#dropDownId').is(':disabled');

Second

Using == true by checking if the attributes value is disabled. attr()

$('#dropDownId').attr('disabled');

whatever you feel fits better , you can use :)

Cheers!

EDIT: As of ~March 2016, Microsoft offers a C/C++ extension for Visual Studio Code and therefor the answer I originally gave is no longer valid.

Visual Studio Code doesn't support C/C++ very well. As such it doesn't >naturally support gcc or gdb within the Visual Studio Code application. The most it will do is syntax highlighting, the advanced features like >intellisense aren't supported with C. You can still compile and debug code >that you wrote in VSC, but you'll need to do that outside the program itself.

The easiest way to do it is to use the End method, which is gives you the cell that you reach by pressing the end key and then a direction when you're on a cell (in this case B6). This won't give you what you expect if B6 or B7 is empty, though.

Dim start_cell As Range
Set start_cell = Range("[Workbook1.xlsx]Sheet1!B6")
Range(start_cell, start_cell.End(xlDown)).Copy Range("[Workbook2.xlsx]Sheet1!A2")

If you can't use End, then you would have to use a loop.

Dim start_cell As Range, end_cell As Range

Set start_cell = Range("[Workbook1.xlsx]Sheet1!B6")
Set end_cell = start_cell

Do Until IsEmpty(end_cell.Offset(1, 0))
    Set end_cell = end_cell.Offset(1, 0)
Loop

Range(start_cell, end_cell).Copy Range("[Workbook2.xlsx]Sheet1!A2")

According to this, you need to assign a height to the element in which the div is contained in order for 100% height to work. Does that work for you?

Just another viewpoint. Performing an "or" in Prolog can also be done with the "disjunct" operator or semi-colon:

registered(X, Y) :-
    X = ct101; X = ct102; X = ct103.

Not entirely an answer to the original post, but a quick and dirty solution for posting a json-object to the server and dynamically generating a download.

Client side jQuery:

var download = function(resource, payload) {
     $("#downloadFormPoster").remove();
     $("<div id='downloadFormPoster' style='display: none;'><iframe name='downloadFormPosterIframe'></iframe></div>").appendTo('body');
     $("<form action='" + resource + "' target='downloadFormPosterIframe' method='post'>" +
      "<input type='hidden' name='jsonstring' value='" + JSON.stringify(payload) + "'/>" +
      "</form>")
      .appendTo("#downloadFormPoster")
      .submit();
}

..and then decoding the json-string at the serverside and setting headers for download (PHP example):

$request = json_decode($_POST['jsonstring']), true);
header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename=export.csv');
header('Pragma: no-cache');

For Ubuntu, you can try:

sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6

For Cent OS/RHEL try :

sudo yum install zlib.i686 ncurses-libs.i686 bzip2-libs.i686 

Then, re-install the Android Studio and get success.

When I try to build docker image zeppelin-highcharts, I find that the base image openjdk:8 also does not have pandas installed. I solved it with this steps.

The c variable already contains the char code!

the simple way I believe is to import it then export it, using the certificate manager in Windows Management Console.

Several ways to do so, here are some possible one-line approaches:

2. Use getch() (need #include <conio.h>).

3. Use getchar() (expected for Enter, need #include <iostream>).

4. Use cin.get() (expected for Enter, need #include <iostream>).

5. Use system("pause") (need #include <iostream>).

   PS: This method will also print Press any key to continue . . . on the screen. (seems perfect choice for you :))

Edit: As discussed here, There is no completely portable solution for this. Question 19.1 of the comp.lang.c FAQ covers this in some depth, with solutions for Windows, Unix-like systems, and even MS-DOS and VMS.

The return type of a procedure is int.

You can also return result sets (as your code currently does) (okay, you can also send messages, which are strings)

Those are the only "returns" you can make. Whilst you can add table-valued parameters to a procedure (see BOL), they're input only.

Edit:

(Or as another poster mentioned, you could also use a Table Valued Function, rather than a procedure)

To view Theme files for ST3, install PackageResourceViewer via PackageControl.

Then, you can use the Ctrl + Shift + P >> PackageResourceViewer: Open Resource to view theme files.

To edit a specific background color, you need to create a new file in your user packages folder Packages/User/SublimeLinter with the same name as the theme currently applied to your sublime text file.

However, if your theme is a 3rd party theme package installed via package control, you can edit the hex value in that file directly, under background. For example:

<dict>
  <dict>
    <key>background</key>
    <string>#073642</string>
  </dict>
</dict>

Otherwise, if you are trying to modify a native sublime theme, add the following to the new file you create (named the same as the native theme, such as Monokai.sublime-color-scheme) with your color choice

{
  "globals":
  {
      "background": "rgb(5,5,5)"
  }
}

Then, you can open the file you wish the syntax / color to be applied to and then go to Syntax-Specific settings (under Preferences) and add the path of the file to the syntax specific settings file like so:

{
    "color_scheme": "Packages/User/SublimeLinter/Monokai.sublime-color-scheme"
}

Note that if you have installed a theme via package control, it probably has the .tmTheme file extension.

If you are wanting to edit the background color of the sidebar to be darker, go to Preferences > Theme > Adaptive.sublime-theme

This my answer based on my personal experience and info gleaned from the accepted answer on this page, if you'd like more information.

it is not possible to pragmatically get the permission... but ill suggest you to put that line of code in try{} catch{} which make your app unfortunately stop... and in catch body make a dialog box which will navigate the user to small tutorial to enable the draw over other apps permission... then on yes button click put this code...

 Intent callSettingIntent= new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION);
            startActivity(callSettingIntent);

this intent is to directly open the list of draw over other apps to manage permissions and then from here it is one click to the draw over other apps Permissions ... i know this is Not the answer you're looking for... but Im doing this in my apps...

It is not an issue it is because of caching...

To overcome this add a timestamp to your endpoint call, e.g. axios.get('/api/products').

After timestamp it should be axios.get(/api/products?${Date.now()}.

It will resolve your 304 status code.

So it seems your best option is going with the padding-bottom countered by negative margin-bottom strategy.

I made two examples. One with <header> inside .container, and another with it outside.

Both versions should work properly. Note the use of the following @media query so that it removes the extra padding on smaller screens...

@media screen and (max-width:991px) {
    .content { padding-top:0; }
}

Other than that, those examples should fix your problem.

I think it's because you didn't specify the width and height for the item.

If you only want to have 2 images in a row, you can try something like this instead of using flex:

item: {
    width: '50%',
    height: '100%',
    overflow: 'hidden',
    alignItems: 'center',
    backgroundColor: 'orange',
    position: 'relative',
    margin: 10,
},

This works for me, hope it helps.

I uninstalled ASP.NET MVC 4 using the Windows Control Panel, then reinstalled it by running AspNetMVC4Setup.exe (which I got from https://www.microsoft.com/en-us/download/details.aspx?id=30683), and that fixed the issue for me.

In other words, I didn't need to use Nuget or Visual Studio.

The most obvious way is:

foreach(var kvp in NewAnimals)
   Animals.Add(kvp.Key, kvp.Value); 
  //use Animals[kvp.Key] = kvp.Value instead if duplicate keys are an issue

Since Dictionary<TKey, TValue>explicitly implements theICollection<KeyValuePair<TKey, TValue>>.Addmethod, you can also do this:

var animalsAsCollection = (ICollection<KeyValuePair<string, string>>) Animals;

foreach(var kvp in NewAnimals)
   animalsAsCollection.Add(kvp);

It's a pity the class doesn't have anAddRangemethod likeList<T> does.

You could use rond

cost_per_person = round(150 / 2, 2)

Note: This answer is outdated. See the answer for newer versions of Flutter.

You can dismiss the keyboard by taking away the focus of the TextFormField and giving it to an unused FocusNode:

FocusScope.of(context).requestFocus(FocusNode());

I would recommend against mixing camel case and underscore separation (like you proposed for struct members). This is confusing. You'd think, hey I have get_length so I should probably have make_subset and then you find out it's actually makeSubset. Use the principle of least astonishment, and be consistent.

I do find CamelCase useful to type names, like structs, typedefs and enums. That's about all, though. For all the rest (function names, struct member names, etc.) I use underscore_separation.

1. Open your Java source code document and navigate to the JTable object you have created inside of your Swing class.

2. Create a new TableModel object that holds a DatePickerTable. You must create the DatePickerTable with a range of date values in MMDDYYYY format. The first value is the begin date and the last is the end date. In code, this looks like:

   TableModel datePicker = new DatePickerTable("01011999","12302000");
   

3. Set the display interval in the datePicker object. By default each day is displayed, but you may set a regular interval. To set a 15-day interval between date options, use this code:

   datePicker.interval = 15;
   

4. Attach your table model into your JTable:

   JTable newtable = new JTable (datePicker);
   

   Your Java application now has a drop-down date selection dialog.

There isn't a 'friend' keyword in C# but one option for testing private methods is to use System.Reflection to get a handle to the method. This will allow you to invoke private methods.

Given a class with this definition:

public class Class1
{
    private int CallMe()
    {
        return 1;
    }
}

You can invoke it using this code:

Class1 c = new Class1();
Type class1Type = c.GetType();
MethodInfo callMeMethod = class1Type.GetMethod("CallMe", BindingFlags.Instance | BindingFlags.NonPublic);

int result = (int)callMeMethod.Invoke(c, null);

Console.WriteLine(result);

If you are using Visual Studio Team System then you can get VS to automatically generate a proxy class with private accessors in it by right clicking the method and selecting "Create Unit Tests..."

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

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

Then you can output the col column to a list:

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

In my humble opinion the best way is to just add a full day in milliseconds, depending on how you factor your code it can mess up if your on the last day of the month.

for example Feb 28 or march 31.

Here is an example of how i would do it:

var current = new Date(); //'Mar 11 2015' current.getTime() = 1426060964567
var followingDay = new Date(current.getTime() + 86400000); // + 1 day in ms
followingDay.toLocaleDateString();

imo this insures accuracy

here is another example i Do not like that can work for you but not as clean that dose the above

var today = new Date('12/31/2015');
var tomorrow = new Date(today);
tomorrow.setDate(today.getDate()+1);
tomorrow.toLocaleDateString();

imho this === 'POOP'

So some of you have had gripes about my millisecond approach because of day light savings time. So Im going to bash this out. First, Some countries and states do not have Day light savings time. Second Adding exactly 24 hours is a full day. If the date number dose not change once a year but then gets fixed 6 months later i don't see a problem there. But for the purpose of being definite and having to deal with allot the evil Date() i have thought this through and now thoroughly hate Date. So this is my new Approach

var dd = new Date(); // or any date and time you care about 
var dateArray =  dd.toISOString().split('T')[0].split('-').concat( dd.toISOString().split('T')[1].split(':') );
// ["2016", "07", "04", "00", "17", "58.849Z"] at Z 

Now for the fun part!

var date = { 
    day: dateArray[2],
    month: dateArray[1],
    year: dateArray[0],
    hour: dateArray[3],
    minutes: dateArray[4],
    seconds:dateArray[5].split('.')[0],
    milliseconds: dateArray[5].split('.')[1].replace('Z','')
}

now we have our Official Valid international Date Object clearly written out at Zulu meridian. Now to change the date

  dd.setDate(dd.getDate()+1); // this gives you one full calendar date forward
  tomorrow.setDate(dd.getTime() + 86400000);// this gives your 24 hours into the future. do what you want with it.

I would add an useful side note and a general suggestion to minimize JPG and PNG.

First of all, ImageMagick reads (or better "guess"...) the input jpeg compression level and so if you don't add -quality NN at all, the output should use the same level as input. Sometimes could be an important feature. Otherwise the default level is -quality 92 (see www.imagemagick.org)

The suggestion is about a really awesome free tool ImageOptim, also for batch process.
You can get smaller jpgs (and pngs as well, especially after the use of the free ImageAlpha [not batch process] or the free Pngyu if you need batch process).
Not only, these tools are for Mac and Win and as Command Line (I suggest installing using Brew and then searching in Brew formulas).

Thread thread = new Thread(Work);
thread.Start(Parameter);

private void Work(object param)
{
    string Parameter = (string)param;
}

The parameter type must be an object.

EDIT:

While this answer isn't incorrect I do recommend against this approach. Using a lambda expression is much easier to read and doesn't require type casting. See here: https://stackoverflow.com/a/1195915/52551

This is how I finally did it! You can put a layer (full sized) over your body with high z-index and, of course hidden. You will make it visible when the window is open, make it focused on click over parent window (the layer), and finally will disappear it when the opened window is closed or submitted or whatever.

      .layer
  {
        position: fixed;
        opacity: 0.7;
        left: 0px;
        top: 0px;
        width: 100%;
        height: 100%;
        z-index: 999999;
        background-color: #BEBEBE;
        display: none;
        cursor: not-allowed;
  }

and layer in the body:

                <div class="layout" id="layout"></div>

function that opens the popup window:

    var new_window;
    function winOpen(){
        $(".layer").show();
        new_window=window.open(srcurl,'','height=750,width=700,left=300,top=200');
    }

keeping new window focused:

         $(document).ready(function(){
             $(".layout").click(function(e) {
                new_window.focus();
            }
        });

and in the opened window:

    function submit(){
        var doc = window.opener.document,
        doc.getElementById("layer").style.display="none";
         window.close();
    }   

   window.onbeforeunload = function(){
        var doc = window.opener.document;
        doc.getElementById("layout").style.display="none";
   }

I hope it would help :-)

You could try something like this if you want to use cut:

echo "1:2:3:4:5" | cut -d ":" -f5

You can also use grep try like this :

echo " 1:2:3:4:5" | grep -o '[^:]*$'

That's because operator overloading is something they specifically left out of the language deliberately. They "cheated" a bit with string concatenation, but beyond that, such functionality doesn't exist.

(disclaimer: I haven't worked with the last 2 major releases of java, so if it's in now, I'll be very surprised)

One approach is to combine the search strings into a regex pattern as in this answer.

Next to the maybe useful, but maybe too symptomatic answers, here is one which tries to help to find the cause of the problem.

Maven is a command-line java tool. That means, it is not a standalone binary, it is a collection of java .jars, interpreted by a jvm (java.exe on windows, java on linux).

The mvn command, is a script. On windows, it is a script called mvn.cmd and on linux, it is a shell script. Thus, if you write: mvn install, what will happen:

1. a command interpreter (/bin/sh or cmd.exe) is called for the actual invoking script
2. this script sets the needed environment variables
3. and finally, it calls a java interpreter with the the required classpath which contain the maven functionality.

The problem is with (2). Fortunately, this script is simply, very simple. For a java programmer it shouldn't be a big trouble to debug a script around 20 lines, even if it is a little bit alien language.

On linux, you can debug shellscripts giving the -x flag to your shell interpreter (which is most probably bash). On windows, you have to find some other way to debug a cmd.exe script. So, instead of mvn install, give the command bash -x mvn install.

The result be like:

+ '[' -z '' ']'
+ '[' -f /etc/mavenrc ']'
+ '[' -f /home/picsa/.mavenrc ']'
+ cygwin=true
+ darwin=false

...not so many things...

+ MAVEN_PROJECTBASEDIR='C:\peter\bin'
+ export MAVEN_PROJECTBASEDIR
+ MAVEN_CMD_LINE_ARGS=' '
+ export MAVEN_CMD_LINE_ARGS
+ exec '/cygdrive/c/Program Files/Java/jdk1.8.0_66/bin/java' -classpath 'C:\peter/boot/plexus-classworlds-*.jar' '-Dclassworlds.conf=C:\peter/bin/m2.conf' '-Dmaven.home=C:\peter' '-Dmaven.multiModuleProjectDirectory=C:\peter\bin' org.codehaus.plexus.classworlds.launcher.Launcher
Fehler: Hauptklasse org.codehaus.plexus.classworlds.launcher.Launcher konnte nicht gefunden oder geladen werden

At the end, you can easily test, which environment variable gone bad, and you can very easily fix your script (or set it what is needed).

This is the best and easy way to import font from google and
this is also a standard method to import font

Paste this code on your index page or on header

<link href='http://fonts.googleapis.com/css?family=Oswald:400,300,700' rel='stylesheet' type='text/css'>

other method is to import on css like this:

@import url(http://fonts.googleapis.com/css?family=Oswald:400,300,700);

on your Css file as this code

body {
  font-family: 'Oswald', sans-serif !important;
}

Note : The @import code line will be the first lines in your css file (style.css, etc.css). They can be used in any of the .css files and should always be the first line in these files. The following is an example:

Take a look at this one: http://code.google.com/p/xswingx/

It is not very difficult to implement it by yourself, btw. A couple of listeners and custom renderer and voila.

If you are using a mac and sublime text 3, this is what you do.

Go to your /Packages/User/ and create a file called Python.sublime-settings.

Typically /Packages/User is inside your ~/Library/Application Support/Sublime Text 3/Packages/User/Python.sublime-settings if you are using mac os x.

Then you put this in the Python.sublime-settings.

{
    "tab_size": 4,
    "translate_tabs_to_spaces": false
}

Credit goes to Mark Byer's answer, sublime text 3 docs and python style guide.

This answer is mostly for readers who had the same issue and stumble upon this and are using sublime text 3 on Mac OS X.

You should be using a class to achieve what you want:

css:

#topbar { width: 100%; height: 40px; background-color: #000; }
#topbar.hide { height: 10px; }

javascript:

  $(document).ready(function(){
    $("#topbar").click(function(){
      if($(this).hasClass('hide')) {
        $(this).animate({height:40},200).removeClass('hide');
      } else { 
        $(this).animate({height:10},200).addClass('hide');
      }
    });
  });

The page you linked states

If an explicit array size is specified, but an shorter initiliazation list is specified, the unspecified elements are set to zero.

Speed issue: Any differences would be negligible for arrays this small. If you work with large arrays and speed is much more important than size, you can have a const array of the default values (initialized at compile time) and then memcpy them to the modifiable array.

you are using incorrect format specifier you should use %% for printing %. Your code should be:

printf("hello%%");

Comparing

# =====================================
x
# Decimal('40800000000.00000000000000')
y
# 40800000000.0

type(x)
# <class 'decimal.Decimal'>
type(y)
# <class 'float'>

x == y
# True
type(x) == type(y)
# False

x
# Decimal('40800000000.00000000000000')
y
# 40800000000.0

So for Python 3, you can switch between any of the three for now.

My Fav:

print("{0:.2E}".format(y))

There is indeed such a tool, Comeau's C++ compiler. . It will generate C code which you can't manually maintain, but that's no problem. You'll maintain the C++ code, and just convert to C on the fly.

Whereas @jbarrueta answer is perfect, in the 2.12 version of Jackson was introduced a new long-awaited type for the @JsonTypeInfo annotation, DEDUCTION.

It is useful for the cases when you have no way to change the incoming json or must not do so. I'd still recommend to use use = JsonTypeInfo.Id.NAME, as the new way may throw an exception in complex cases when it has no way to determine which subtype to use.

Now you can simply write

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import com.fasterxml.jackson.annotation.JsonSubTypes;
import com.fasterxml.jackson.annotation.JsonTypeInfo;

@JsonIgnoreProperties(ignoreUnknown = true)
@JsonTypeInfo(use = JsonTypeInfo.Id.DEDUCTION)
@JsonSubTypes({
    @JsonSubTypes.Type(Dog.class),
    @JsonSubTypes.Type(Cat.class) }
)
public abstract class Animal {

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

And it will produce {"name":"ruffus", "breed":"english shepherd"} and {"name":"goya", "favoriteToy":"mice"}

Once again, it's safer to use NAME if some of the fields may be not present, like breed or favoriteToy.

Just a quick little function I drummed up that moves DIVs from their current spot to a target spot, one pixel step at a time. I tried to comment as best as I could, but the part you're interested in, is in example 1 and example 2, right after [$(function() { // jquery document.ready]. Put your bounds checking code there, and then exit the interval if conditions are met. Requires jQuery.

First the Demo: http://jsfiddle.net/pnYWY/

First the DIVs...

<style>
  .moveDiv {
    position:absolute;
    left:20px;
    top:20px;
    width:10px;
    height:10px;
    background-color:#ccc;
  }

  .moveDivB {
    position:absolute;
    left:20px;
    top:20px;
    width:10px;
    height:10px;
    background-color:#ccc;
  }
</style>


<div class="moveDiv"></div>
<div class="moveDivB"></div>

example 1) Start

// first animation (fire right away)
var myVar = setInterval(function(){
    $(function() { // jquery document.ready

        // returns true if it just took a step
        // returns false if the div has arrived
        if( !move_div_step(55,25,'.moveDiv') )
        {
            // arrived...
            console.log('arrived'); 
            clearInterval(myVar);
        }

    });
},50); // set speed here in ms for your delay

example 2) Delayed Start

// pause and then fire an animation..
setTimeout(function(){
    var myVarB = setInterval(function(){
        $(function() { // jquery document.ready
            // returns true if it just took a step
            // returns false if the div has arrived
            if( !move_div_step(25,55,'.moveDivB') )
            {
                // arrived...
                console.log('arrived'); 
                clearInterval(myVarB);
            }
        });
    },50); // set speed here in ms for your delay
},5000);// set speed here for delay before firing

Now the Function:

function move_div_step(xx,yy,target) // takes one pixel step toward target
{
    // using a line algorithm to move a div one step toward a given coordinate.
    var div_target = $(target);

    // get current x and current y
    var x = div_target.position().left; // offset is relative to document; position() is relative to parent;
    var y = div_target.position().top;

    // if x and y are = to xx and yy (destination), then div has arrived at it's destination.
    if(x == xx && y == yy)
        return false;

    // find the distances travelled
    var dx = xx - x;
    var dy = yy - y;

    // preventing time travel
    if(dx < 0)          dx *= -1;
    if(dy < 0)          dy *= -1;

    // determine speed of pixel travel...
    var sx=1, sy=1;

    if(dx > dy)         sy = dy/dx;
    else if(dy > dx)    sx = dx/dy;

    // find our one...
    if(sx == sy) // both are one..
    {
        if(x <= xx) // are we going forwards?
        {
            x++; y++;
        }
        else  // .. we are going backwards.
        {
            x--; y--;
        }       
    }
    else if(sx > sy) // x is the 1
    {
        if(x <= xx) // are we going forwards..?
            x++;
        else  // or backwards?
            x--;

        y += sy;
    }
    else if(sy > sx) // y is the 1 (eg: for every 1 pixel step in the y dir, we take 0.xxx step in the x
    {
        if(y <= yy) // going forwards?
            y++;
        else  // .. or backwards?
            y--;

        x += sx;
    }

    // move the div
    div_target.css("left", x);
    div_target.css("top",  y);

    return true;
}  // END :: function move_div_step(xx,yy,target)

Kinda late, but you need to access the original event, not the jQuery massaged one. Also, since these are multi-touch events, other changes need to be made:

$('#box').live('touchstart', function(e) {
  var xPos = e.originalEvent.touches[0].pageX;
});

If you want other fingers, you can find them in other indices of the touches list.

UPDATE FOR NEWER JQUERY:

$(document).on('touchstart', '#box', function(e) {
  var xPos = e.originalEvent.touches[0].pageX;
});

The java.net blog had a class the other day that might have done what you want (but it is down right now so I cannot check).

This code here could probably be modified to do what you want:

http://svn.apache.org/repos/asf/incubator/shindig/trunk/java/common/src/main/java/org/apache/shindig/common/uri/UriBuilder.java

Here is the one I was thinking of from java.net: https://urlencodedquerystring.dev.java.net/

Download https://github.com/douglascrockford/JSON-js/blob/master/json2.js, include it and do

var json_data = JSON.stringify(obj);

I built an extension called Checkpoints, an alternative to Local History. Checkpoints has support for viewing history for all files (that has checkpoints) in the tree view, not just the currently active file. There are some other minor differences aswell, but overall they are pretty similar.

Your question about performance is moot—both functions are very fast. The speed of your code will be determined by what you do with the random numbers.

However it's important you understand the difference in behaviour of those two functions. One does random sampling with replacement, the other does random sampling without replacement.

You can't remove, nor can you add to a fixed-size-list of Arrays.

But you can create your sublist from that list.

list = list.subList(0, list.size() - (list.size() - count));

public static String SelectRandomFromTemplate(String template, int count) {
   String[] split = template.split("\\|");
   List<String> list = Arrays.asList(split);
   Random r = new Random();
   while( list.size() > count ) {
      list = list.subList(0, list.size() - (list.size() - count));
   }
   return StringUtils.join(list, ", ");
}

*Other way is

ArrayList<String> al = new ArrayList<String>(Arrays.asList(template));

this will create ArrayList which is not fixed size like Arrays.asList

If you need async: false in your ajax, you should use success instead of .done. Else you better to use .done. This is from jQuery official site:

As of jQuery 1.8, the use of async: false with jqXHR ($.Deferred) is deprecated; you must use the success/error/complete callback options instead of the corresponding methods of the jqXHR object such as jqXHR.done().

The main difference between statement level trigger is below :

statement level trigger : based on name it works if any statement is executed. Does not depends on how many rows or any rows effected.It executes only once. Exp : if you want to update salary of every employee from department HR and at the end you want to know how many rows get effected means how many got salary increased then use statement level trigger. please note that trigger will execute even if zero rows get updated because it is statement level trigger is called if any statement has been executed. No matters if it is affecting any rows or not.

Row level trigger : executes each time when an row is affected. if zero rows affected.no row level trigger will execute.suppose if u want to delete one employye from emp table whose department is HR and u want as soon as employee deleted from emp table the count in dept table from HR section should be reduce by 1.then you should opt for row level trigger.

Vue definitely has some bugs around this. I find that although registering a component like so

components: { MyComponent }

will work most of the time, and can be used as MyComponent or my-component automatically, sometimes you have to spell it out as such

components: { 'my-component' : MyComponent }

And use it strictly as my-component

Driver for Huawei was not found. So I've been using the universal ADB driver:

• Download this:
• Extract ADBDriverInstaller and Run the file. Make sure you have connected your device through USB to your computer.
• A window is displayed.
• Click Install.
• A dialog box will appear. It will ask you to press the Restart button.

Before doing that read this link:

(The above. in brief, says to press Restart button in the dialog box. Select Troubleshoot. Select Advance Option. Select Startup Setting. Press Restart. After system's been restarted, on the appearing screen press 7)

• When PC has been Restarted, Run the ADBDriverInstaller file again. Select your device from the options. Press install.

And it's done :)

An interesting project which could help you out in your task is JSS.

JSS is a better abstraction over CSS. It uses JavaScript as a language to describe styles in a declarative and maintainable way. It is a high performance JS to CSS compiler which works at runtime in the browsers and server-side.

JSS library allows you to inject in the DOM/head section using the .attach() function.

Repl online version for evaluation.

Further information on JSS.

An example:

// Use plugins.
jss.use(camelCase())

// Create your style.
const style = {
  myButton: {
    color: 'green'
  }
}

// Compile styles, apply plugins.
const sheet = jss.createStyleSheet(style)

// If you want to render on the client, insert it into DOM.
sheet.attach()

If you want to keep your \t equal to 8 spaces then consider setting:

   set softtabstop=2 tabstop=8 shiftwidth=2

This will give you two spaces per <TAB> press, but actual \t in your code will still be viewed as 8 characters.

Where is this list of products that you're trying to determine the existence of? If that list exists within another table you could do this

declare @are_equal bit
declare @products int

SELECT @products = 
     count(pl.id)
FROM ProductList pl
JOIN Products p
ON pl.productId = p.productId

select @are_equal = @products == select count(id) from ProductList

Edit:

Then do ALL the work in C#. Cache the actual list of products in your application somewhere, and do a LINQ query.

var compareProducts = new List<Product>(){p1,p2,p3,p4,p5};
var found = From p in GetAllProducts()
            Join cp in compareProducts on cp.Id equals p.Id
            select p;

return compareProducts.Count == found.Count;

This prevents constructing SQL queries by hand, and keeps all your application logic in the application.

I had the same problem with mediawiki, this was because the server denied embedding the page into an iframe for security reasons.

I solved it writing

$wgEditPageFrameOptions = "SAMEORIGIN"; 

into the mediawiki php config file.

Hope it helps.

It depends on what you are developing.

A content-oriented website will have its content changing frequently and a Website is better for that.

An application tends to have its data stored in a database and its pages and code change rarely. In this case it's better to have a Web application where deployment of assemblies is much more controlled and has better support for unit testing.

Read this https://docs.djangoproject.com/en/dev/howto/static-files/:

For local development, if you are using runserver or adding staticfiles_urlpatterns to your URLconf, you’re done with the setup – your static files will automatically be served at the default (for newly created projects) STATIC_URL of /static/.

And try:

~/tmp$ django-admin.py startproject myprj
~/tmp$ cd myprj/
~/tmp/myprj$ chmod a+x manage.py
~/tmp/myprj$ ./manage.py startapp myapp

Then add 'myapp' to INSTALLED_APPS (myprj/settings.py).

~/tmp/myprj$ cd myapp/
~/tmp/myprj/myapp$ mkdir static
~/tmp/myprj/myapp$ echo 'alert("hello!");' > static/hello.js
~/tmp/myprj/myapp$ mkdir templates
~/tmp/myprj/myapp$ echo '<script src="{{ STATIC_URL }}hello.js"></script>' > templates/hello.html

Edit myprj/urls.py:

from django.conf.urls import patterns, include, url
from django.views.generic import TemplateView

class HelloView(TemplateView):
    template_name = "hello.html"

urlpatterns = patterns('',
    url(r'^$', HelloView.as_view(), name='hello'),
)

And run it:

~/tmp/myprj/myapp$ cd ..
~/tmp/myprj$ ./manage.py runserver

It works!

In my case it was pretty much what Mayank Shukla's top answer says. The only detail was that my state was lacking completely the property I was defining.

For example, if you have this state:

state = {
    "a" : "A",
    "b" : "B",
}

If you're expanding your code, you might want to add a new prop so, someplace else in your code you might create a new property c whose value is not only undefined on the component's state but the property itself is undefined.

To solve this just make sure to add c into your state and give it a proper initial value.

e.g.,

state = {
    "a" : "A",
    "b" : "B",
    "c" : "C", // added and initialized property!
}

Hope I was able to explain my edge case.

Using a cookie to provide the CSRF token to the client does not allow a successful attack because the attacker cannot read the value of the cookie and therefore cannot put it where the server-side CSRF validation requires it to be.

The attacker will be able to cause a request to the server with both the auth token cookie and the CSRF cookie in the request headers. But the server is not looking for the CSRF token as a cookie in the request headers, it's looking in the payload of the request. And even if the attacker knows where to put the CSRF token in the payload, they would have to read its value to put it there. But the browser's cross-origin policy prevents reading any cookie value from the target website.

The same logic does not apply to the auth token cookie, because the server is expects it in the request headers and the attacker does not have to do anything special to put it there.

URI (Uniform Resource Identifier) according to Wikipedia:

a string of characters used to identify a resource.

URL (Uniform Resource Locator) is a URI that implies an interaction mechanism with resource. for example https://www.google.com specifies the use of HTTP as the interaction mechanism. Not all URIs need to convey interaction-specific information.

URN (Uniform Resource Name) is a specific form of URI that has urn as it's scheme. For more information about the general form of a URI refer to https://en.wikipedia.org/wiki/Uniform_Resource_Identifier#Syntax

IRI (International Resource Identifier) is a revision to the definition of URI that allows us to use international characters in URIs.

The best is to check like:

    let someArray: string[] = [];
    let hasAny1: boolean = !!someArray && !!someArray.length;
    let hasAny2: boolean = !!someArray && someArray.length > 0; //or like this
    console.log("And now on empty......", hasAny1, hasAny2);

I copied you code and made some minor modifications, and it seems to work fine. I can set the viewmodels PhoneBookEnty property and the selected item in the combobox changes, and I can change the selected item in the combobox and the view models PhoneBookEntry property is set correctly.

Here is my XAML content:

<Window x:Class="WpfApplication6.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Window1" Height="300" Width="300">
<Grid>
    <StackPanel>
        <Button Click="Button_Click">asdf</Button>
        <ComboBox ItemsSource="{Binding Path=PhonebookEntries}"
                  DisplayMemberPath="Name"
                  SelectedValuePath="Name"
                  SelectedValue="{Binding Path=PhonebookEntry}" />
    </StackPanel>
</Grid>
</Window>

And here is my code-behind:

namespace WpfApplication6
{

    /// <summary>
    /// Interaction logic for Window1.xaml
    /// </summary>
    public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();
            ConnectionViewModel vm = new ConnectionViewModel();
            DataContext = vm;
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            ((ConnectionViewModel)DataContext).PhonebookEntry = "test";
        }
    }

    public class PhoneBookEntry
    {
        public string Name { get; set; }

        public PhoneBookEntry(string name)
        {
            Name = name;
        }

        public override string ToString()
        {
            return Name;
        }
    }

    public class ConnectionViewModel : INotifyPropertyChanged
    {
        public ConnectionViewModel()
        {
            IList<PhoneBookEntry> list = new List<PhoneBookEntry>();
            list.Add(new PhoneBookEntry("test"));
            list.Add(new PhoneBookEntry("test2"));
            _phonebookEntries = new CollectionView(list);
        }

        private readonly CollectionView _phonebookEntries;
        private string _phonebookEntry;

        public CollectionView PhonebookEntries
        {
            get { return _phonebookEntries; }
        }

        public string PhonebookEntry
        {
            get { return _phonebookEntry; }
            set
            {
                if (_phonebookEntry == value) return;
                _phonebookEntry = value;
                OnPropertyChanged("PhonebookEntry");
            }
        }

        private void OnPropertyChanged(string propertyName)
        {
            if (PropertyChanged != null)
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
        public event PropertyChangedEventHandler PropertyChanged;
    }
}

Edit: Geoffs second example does not seem to work, which seems a bit odd to me. If I change the PhonebookEntries property on the ConnectionViewModel to be of type ReadOnlyCollection, the TwoWay binding of the SelectedValue property on the combobox works fine.

Maybe there is an issue with the CollectionView? I noticed a warning in the output console:

System.Windows.Data Warning: 50 : Using CollectionView directly is not fully supported. The basic features work, although with some inefficiencies, but advanced features may encounter known bugs. Consider using a derived class to avoid these problems.

Edit2 (.NET 4.5): The content of the DropDownList can be based on ToString() and not of DisplayMemberPath, while DisplayMemberPath specifies the member for the selected and displayed item only.

I collected some information on the internet and prepared the script that requires no external tool: See my response here. Hope it's helpful.

The code that is written in the question has a bug in it

Your arraylist contains strings of " 1" " 3" " 4" " 9" and " 2" (note the spaces)

So IndexOf(4) will find nothing because 4 is an int, and even "tostring" would convert it to of "4" and not " 4", and nothing will get removed.

An arraylist is the correct way to go to do what you want.

public OnClickListener moreListener = new OnClickListener() {

    @Override
      public void onClick(View v) {
          adapter.add("aaaa")
      }
}

For educational purposes, let me add two more Numpy solutions (which are slower than the cumsum solution):

import numpy as np
from numpy.lib.stride_tricks import as_strided

def ra_strides(arr, window):
    ''' Running average using as_strided'''
    n = arr.shape[0] - window + 1
    arr_strided = as_strided(arr, shape=[n, window], strides=2*arr.strides)
    return arr_strided.mean(axis=1)

def ra_add(arr, window):
    ''' Running average using add.reduceat'''
    n = arr.shape[0] - window + 1
    indices = np.array([0, window]*n) + np.repeat(np.arange(n), 2)
    arr = np.append(arr, 0)
    return np.add.reduceat(arr, indices )[::2]/window

Functions used: as_strided, add.reduceat

It is most likely due to a cross-origin request, but it may not be. For me, I had been debugging an API and had set the Access-Control-Allow-Origin to *, but it appears that recent versions of Chrome are requiring an extra header. Try prepending the following to your file if you are using PHP:

header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");

Make sure that you haven't already used header in another file, or you will get a nasty error. See the docs for more.

no such table found is mainly when you have not opened the SQLiteOpenHelper class with getwritabledata() and before this you also have to call make constructor with databasename & version. And OnUpgrade is called whenever there is upgrade value in version number given in SQLiteOpenHelper class.

Below is the code snippet (No such column found may be because of spell in column name):

public class database_db {
    entry_data endb;
    String file_name="Record.db";
    SQLiteDatabase sq;
    public database_db(Context c)
    {
        endb=new entry_data(c, file_name, null, 8);
    }
    public database_db open()
    {
        sq=endb.getWritableDatabase();
        return this;
    }
    public Cursor getdata(String table)
    {
        return sq.query(table, null, null, null, null, null, null);
    }
    public long insert_data(String table,ContentValues value)
    {
        return sq.insert(table, null, value);
    }
    public void close()
    {
        sq.close();
    }
    public void delete(String table)
    {
        sq.delete(table,null,null);
    }
}
class entry_data extends SQLiteOpenHelper
{

    public entry_data(Context context, String name, SQLiteDatabase.CursorFactory factory,
                      int version) {
        super(context, name, factory, version);
        // TODO Auto-generated constructor stub
    }

    @Override
    public void onCreate(SQLiteDatabase sqdb) {
        // TODO Auto-generated method stub

        sqdb.execSQL("CREATE TABLE IF NOT EXISTS 'YOUR_TABLE_NAME'(Column_1 text not null,Column_2 text not null);");

    }

    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
          onCreate(db);
    }

}

Make sure ~/.ssh/known_hosts is writable. That fixed it for me.

I wrote a module that handles colors in Linux, OS X, and Windows. It supports all 16 colors on all platforms, you can set foreground and background colors at different times, and the string objects give sane results for things like len() and .capitalize().

I know this is old but none of the above solutions worked for me. After extensive debugging, I figured out the issue. The solution is setting the android:windowTranslucentStatus attribute to false in my styles.xml

From a usability perspective, it's usually better to leave the button enabled but show an error message if someone tries to submit an incomplete form. It drives me nuts when the button I want to click is disabled and there is no clue to why.

val navigationView: NavigationView =  findViewById(R.id.nv)
val header: View = navigationView.getHeaderView(0)
val tv: TextView = header.findViewById(R.id.profilename)
tv.text = "Your_Text"

This will fix your problem <3

The problem is on this line:

oShell.run "cmd.exe /C copy "S:Claims\Sound.wav" "C:\WINDOWS\Media\Sound.wav"

Your first quote next to "S:Claims" ends the string; you need to escape the quotes around your files with a second quote, like this:

oShell.run "cmd.exe /C copy ""S:\Claims\Sound.wav"" ""C:\WINDOWS\Media\Sound.wav"" "

You also have a typo in S:Claims\Sound.wav, should be S:\Claims\Sound.wav.

I also assume the apostrophe before Dim oShell and after Set oShell = Nothing are typos as well.

As of iOS 11 this is publicly available in UITableViewDelegate. Here's some sample code:

The universal tool for string formatting, sprintf:

$stamp = sprintf('%s%02s', $year, $month);

http://php.net/manual/en/function.sprintf.php

Basically:

$lastDate = date("Y-m-t", strtotime($query_d));

Date t parameter return days number in current month.

You are trying to use . as a . not as the wildcard for any character. Use \. instead to indicate a period.

ad 1. It does not implement its methods.

ad 4. The purpose of one interface extending, not implementing another, is to build a more specific interface. For example, SortedMap is an interface that extends Map. A client not interested in the sorting aspect can code against Map and handle all the instances of for example TreeMap, which implements SortedMap. At the same time, another client interested in the sorted aspect can use those same instances through the SortedMap interface.

In your example you are repeating the methods from the superinterface. While legal, it's unnecessary and doesn't change anything in the end result. The compiled code will be exactly the same whether these methods are there or not. Whatever Eclipse's hover says is irrelevant to the basic truth that an interface does not implement anything.

You can, in Firefox it works, add the attribute target="_newtab" to the anchor to force the opening of a new tab.

<a href="some url" target="_newtab">content of the anchor</a>

In javascript you can use

window.open('page.html','_newtab');

Said that, I partially agree with Sam. You shouldn't force user to open new pages or new tab without showing them a hint on what is going to happen before they click on the link.

Let me know if it works on other browser too (I don't have a chance to try it on other browser than Firefox at the moment).

Edit: added reference for ie7 Maybe this link can be useful

You can also add a converter to your JsonSerializer if you don't want to use JsonConverter attribute:

string SerializedResponse = JsonConvert.SerializeObject(
     objToSerialize, 
     new Newtonsoft.Json.Converters.StringEnumConverter()
); 

It will work for every enum it sees during that serialization.

1. If you want to scroll the page vertically to perform some action, you can do it using the following JavaScript. ((JavascriptExecutor)driver).executeScript(“window.scrollTo(0, document.body.scrollHeight)”);

       Where ‘JavascriptExecutor’ is an interface, which helps executing JavaScript through Selenium WebDriver. You can use the following code to import.
   

import org.openqa.selenium.JavascriptExecutor;

2.If you want to scroll at a particular element, you need to use the following JavaScript.

WebElement element = driver.findElement(By.xpath(“//input [@id=’email’]”));((JavascriptExecutor) driver).executeScript(“arguments[0].scrollIntoView();”, element);

Where ‘element’ is the locator where you want to scroll.

3.If you want to scroll at a particular coordinate, use the following JavaScript.
((JavascriptExecutor)driver).executeScript(“window.scrollBy(200,300)”); Where ‘200,300’ are the coordinates.

4.If you want to scroll up in a vertical direction, you can use the following JavaScript. ((JavascriptExecutor) driver).executeScript(“window.scrollTo(document.body.scrollHeight,0)”);

5. If you want to scroll horizontally in the right direction, use the following JavaScript. ((JavascriptExecutor)driver).executeScript(“window.scrollBy(2000,0)”);

6. If you want to scroll horizontally in the left direction, use the following JavaScript. ((JavascriptExecutor)driver).executeScript(“window.scrollBy(-2000,0)”);

Using count(*) over(partition by...) provides a simple and efficient means to locate unwanted repetition, whilst also list all affected rows and all wanted columns:

SELECT
    t.*
FROM (
    SELECT
        s.*
      , COUNT(*) OVER (PARTITION BY s.name, s.city) AS qty
    FROM stuff s
    ) t
WHERE t.qty > 1
ORDER BY t.name, t.city

While most recent RDBMS versions support count(*) over(partition by...) MySQL V 8.0 introduced "window functions", as seen below (in MySQL 8.0)

CREATE TABLE stuff(
   id   INTEGER  NOT NULL
  ,name VARCHAR(60) NOT NULL
  ,city VARCHAR(60) NOT NULL
);

INSERT INTO stuff(id,name,city) VALUES 
  (904834,'jim','London')
, (904835,'jim','London')
, (90145,'Fred','Paris')
, (90132,'Fred','Paris')
, (90133,'Fred','Paris')

, (923457,'Barney','New York') # not expected in result
;

SELECT
    t.*
FROM (
    SELECT
        s.*
      , COUNT(*) OVER (PARTITION BY s.name, s.city) AS qty
    FROM stuff s
    ) t
WHERE t.qty > 1
ORDER BY t.name, t.city

    id | name | city   | qty

Window functions. MySQL now supports window functions that, for each row from a query, perform a calculation using rows related to that row. These include functions such as RANK(), LAG(), and NTILE(). In addition, several existing aggregate functions now can be used as window functions; for example, SUM() and AVG(). For more information, see Section 12.21, “Window Functions”.

This service is the best in online image map editing I found so far : http://www.image-maps.com/

... but it is in fact a bit weak and I personnaly don't use it anymore. I switched to GIMP and it is indeed pretty good.

The answer from mobius is not wrong but in some cases you must use imagemaps even if it seems a bit old and rusty. For instance, in a newsletter, where you can't use HTML/CSS to do what you want.

There are multiple ways to do it. The actual solution depends on the purpose.

The variable values are usually stored in either a list of assignments or a shell script that is run at the start of the system or user session. In case of the shell script you must use a specific shell syntax and export or set commands.

System wide

1. /etc/environment List of unique assignments, allows references. Perfect for adding system-wide directories like /usr/local/something/bin to PATH variable or defining JAVA_HOME. Used by PAM and SystemD.
2. /etc/environment.d/*.conf List of unique assignments, allows references. Perfect for adding system-wide directories like /usr/local/something/bin to PATH variable or defining JAVA_HOME. The configuration can be split into multiple files, usually one per each tool (Java, Go, NodeJS). Used by SystemD that by design do not pass those values to user login shells.
3. /etc/xprofile Shell script executed while starting X Window System session. This is run for every user that logs into X Window System. It is a good choice for PATH entries that are valid for every user like /usr/local/something/bin. The file is included by other script so use POSIX shell syntax not the syntax of your user shell.
4. /etc/profile and /etc/profile.d/* Shell script. This is a good choice for shell-only systems. Those files are read only by shells in login mode.
5. /etc/<shell>.<shell>rc. Shell script. This is a poor choice because it is single shell specific. Used in non-login mode.

User session

1. ~/.pam_environment. List of unique assignments, no references allowed. Loaded by PAM at the start of every user session irrelevant if it is an X Window System session or shell. You cannot reference other variables including HOME or PATH so it has limited use. Used by PAM.
2. ~/.xprofile Shell script. This is executed when the user logs into X Window System system. The variables defined here are visible to every X application. Perfect choice for extending PATH with values such as ~/bin or ~/go/bin or defining user specific GOPATH or NPM_HOME. The file is included by other script so use POSIX shell syntax not the syntax of your user shell. Your graphical text editor or IDE started by shortcut will see those values.
3. ~/.profile, ~/.<shell>_profile, ~/.<shell>_login Shell script. It will be visible only for programs started from terminal or terminal emulator. It is a good choice for shell-only systems. Used by shells in login mode.
4. ~/.<shell>rc. Shell script. This is a poor choice because it is single shell specific. Used by shells in non-login mode.

Notes

Gnome on Wayland starts user login shell to get the environment. It effectively uses login shell configurations ~/.profile, ~/.<shell>_profile, ~/.<shell>_login files.

As of jquery 3.0 you can use $.uniqueSort(ARRAY)

Example

array = ["1","2","1","2"]
$.uniqueSort(array)
=> ["1", "2"]

For Python 2 try:

print unicode(string, 'unicode-escape')

For Python 3 try:

import os
string = "002 Could've Would've Should've"
os.system('echo ' + string)

pip install win-unicode-console
py -mrun your_script.py

    for (id in response.data) { 
        var homie=response.data[id].id         
        FB.api(homie+'/albums?access_token='+accessToken, function (aresponse) {
          for (album in aresponse.data) {
            if (aresponse.data[album].name == "Profile Pictures") {                      
              FB.api(aresponse.data[album].id + "/photos", function(aresponse) {
                console.log(aresponse.data[0].images[0].source); 
              });                  
            }
          }   
        });
    }
  });
}

See the MDN section on Promises. In particular, look at the return type of then().

To log in, the user-agent has to submit a request to the server and wait to receive a response. Since making your application totally stop execution during a request round-trip usually makes for a bad user experience, practically every JS function that logs you in (or performs any other form of server interaction) will use a Promise, or something very much like it, to deliver results asynchronously.

Now, also notice that return statements are always evaluated in the context of the function they appear in. So when you wrote:

let AuthUser = data => {
  return google
    .login(data.username, data.password)
    .then( token => {
      return token;
    });
};

the statement return token; meant that the anonymous function being passed into then() should return the token, not that the AuthUser function should. What AuthUser returns is the result of calling google.login(username, password).then(callback);, which happens to be a Promise.

Ultimately your callback token => { return token; } does nothing; instead, your input to then() needs to be a function that actually handles the token in some way.

The below snippet works fine for me(I used the size())

String itemId;
            for (int i = 0; i < itemList.size(); i++) {
            JSONObject itemObj = (JSONObject)itemList.get(i);
            itemId=(String) itemObj.get("ItemId");
            System.out.println(itemId);
            }

If it is wrong to use use size() kindly advise

As simple as that.

var str = '{"id":1,"name":"Test1"},{"id":2,"name":"Test2"}';
 dataObj = JSON.parse(str);

use MYSQL as Example: 1) use database connection pools: for Example: Apache Commons DBCP , also, you need basicDataSource jar package in your classpath

@Bean
public BasicDataSource dataSource() {
    BasicDataSource ds = new BasicDataSource();
    ds.setDriverClassName("com.mysql.jdbc.Driver");
    ds.setUrl("jdbc:mysql://localhost:3306/gene");
    ds.setUsername("root");
    ds.setPassword("root");
    return ds;
}

2)use JDBC-based Driver it is usually used if you don't consider connection pool:

@Bean
public DataSource dataSource(){
    DriverManagerDataSource ds = new DriverManagerDataSource();
    ds.setDriverClassName("com.mysql.jdbc.Driver");
    ds.setUrl("jdbc:mysql://localhost:3306/gene");
    ds.setUsername("root");
    ds.setPassword("root");
    return ds;
}

You can use set -e as a prefix for the for-loop. Example:

all:
    set -e; for a in 1 2 3; do /bin/false; echo $$a; done

make will exit immediately with an exit code <> 0.

To catch errors with subprocess.check_output(), you can use CalledProcessError. If you want to use the output as string, decode it from the bytecode.

# \return String of the output, stripped from whitespace at right side; or None on failure.
def runls():
    import subprocess
    try:
        byteOutput = subprocess.check_output(['ls', '-a'], timeout=2)
        return byteOutput.decode('UTF-8').rstrip()
    except subprocess.CalledProcessError as e:
        print("Error in ls -a:\n", e.output)
        return None

In webpack.config.js replace loaders: [..] with rules: [..] It worked for me.

I disagree with this kind of path

GET /companies/{companyId}/departments

If you want to get departments, I think it's better to use a /departments resource

GET /departments?companyId=123

I suppose you have a companies table and a departments table then classes to map them in the programming language you use. I also assume that departments could be attached to other entities than companies, so a /departments resource is straightforward, it's convenient to have resources mapped to tables and also you don't need as many endpoints since you can reuse

GET /departments?companyId=123

for any kind of search, for instance

GET /departments?name=xxx
GET /departments?companyId=123&name=xxx
etc.

If you want to create a department, the

POST /departments

resource should be used and the request body should contain the company ID (if the department can be linked to only one company).

You can use the HTMLOptionsCollection.namedItem() That means that you have to define your select options to have a name attribute and have the value of the displayed text. e.g California

Have you considered just doing whatever you want to do in the if rather than looking before you leap?

I.e., if you want to check for the existence of a directory before you enter it, try just doing this:

if pushd /path/you/want/to/enter; then
    # Commands you want to run in this directory
    popd
fi

If the path you give to pushd exists, you'll enter it and it'll exit with 0, which means the then portion of the statement will execute. If it doesn't exist, nothing will happen (other than some output saying the directory doesn't exist, which is probably a helpful side-effect anyways for debugging).

It seems better than this, which requires repeating yourself:

if [ -d /path/you/want/to/enter ]; then
    pushd /path/you/want/to/enter
    # Commands you want to run in this directory
    popd
fi

The same thing works with cd, mv, rm, etc... if you try them on files that don't exist, they'll exit with an error and print a message saying it doesn't exist, and your then block will be skipped. If you try them on files that do exist, the command will execute and exit with a status of 0, allowing your then block to execute.

Every maven project should stop depending on xerces, they probably don't really. XML APIs and an Impl has been part of Java since 1.4. There is no need to depend on xerces or XML APIs, its like saying you depend on Java or Swing. This is implicit.

If I was boss of a maven repo I'd write a script to recursively remove xerces dependencies and write a read me that says this repo requires Java 1.4.

Anything that actually breaks because it references Xerces directly via org.apache imports needs a code fix to bring it up to Java 1.4 level (and has done since 2002) or solution at JVM level via endorsed libs, not in maven.

I'm using python 3.4, requests 2.19.1:

'urllib3' is the logger to get now (no longer 'requests.packages.urllib3'). Basic logging will still happen without setting http.client.HTTPConnection.debuglevel

This is a property setting rather than a valued attribute

These property settings are values per see and don't need any assignments to them. When they are present, an element has this boolean property set to true, when they're absent they're false.

<input type="text" readonly />

It's actually browsers that are liberal toward value assignment to them. If you assign any value to them it will simply get ignored. Browsers will only see the presence of a particular property and ignore the value you're trying to assign to them.

This is of course good, because some frameworks don't have the ability to add such properties without providing their value along with them. Asp.net MVC Html helpers are one of them. jQuery used to be the same until version 1.6 where they added the concept of properties.

There are of course some implications that are related to XHTML as well, because attributes in XML need values in order to be well formed. But that's a different story. Hence browsers have to ignore value assignments.

Anyway. Never mind the value you're assigning to them as long as the name is correctly spelled so it will be detected by browsers. But for readability and maintainability it's better to assign meaningful values to them like:

readonly="true" <-- arguably best human readable
readonly="readonly"

as opposed to

readonly="johndoe"
readonly="01/01/2000"

that may confuse future developers maintaining your code and may interfere with future specification that may define more strict rules to such property settings.

Unpopular opinion from 2020:

When it comes to ASP.NET apps I still prefer WebClient over HttpClient because:

1. The modern implementation comes with async/awaitable task-based methods
2. Has smaller memory footprint and 2x-5x faster (other answers already mention that)
3. It's suggested to "reuse a single instance of HttpClient for the lifetime of your application". But ASP.NET has no "lifetime of application", only lifetime of a request.

You need to use WebConfigurationManager.OpenWebConfiguration(): For Example:

Dim myConfiguration As Configuration = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~")
myConfiguration.ConnectionStrings.ConnectionStrings("myDatabaseName").ConnectionString = txtConnectionString.Text
myConfiguration.AppSettings.Settings.Item("myKey").Value = txtmyKey.Text
myConfiguration.Save()

I think you might also need to set AllowLocation in machine.config. This is a boolean value that indicates whether individual pages can be configured using the element. If the "allowLocation" is false, it cannot be configured in individual elements.

Finally, it makes a difference if you run your application in IIS and run your test sample from Visual Studio. The ASP.NET process identity is the IIS account, ASPNET or NETWORK SERVICES (depending on IIS version).

Might need to grant ASPNET or NETWORK SERVICES Modify access on the folder where web.config resides.

you can simply add a method (setAttributes, with "s" at the end) to "Element" prototype like:

Element.prototype.setAttributes = function(obj){
  for(var prop in obj) {
    this.setAttribute(prop, obj[prop])
  }
}

you can define it in one line:

Element.prototype.setAttributes = function(obj){ for(var prop in obj) this.setAttribute(prop, obj[prop]) }

and you can call it normally as you call the other methods. The attributes are given as an object:

elem.setAttributes({"src": "http://example.com/something.jpeg", "height": "100%", "width": "100%"})

you can add an if statement to throw an error if the given argument is not an object.

I fixed all my asp.net problems simply by creating a new user called IUSER with a password and added it the Network Service and User Groups. Then create all your virtual sites and applications set authentication to IUSER with its password.. set high level file access to include IUSER and BAM it fixed at least 3-4 issues including this one..

Supervised learning: say a kid goes to kinder-garden. here teacher shows him 3 toys-house,ball and car. now teacher gives him 10 toys. he will classify them in 3 box of house,ball and car based on his previous experience. so kid was first supervised by teachers for getting right answers for few sets. then he was tested on unknown toys.

Unsupervised learning: again kindergarten example.A child is given 10 toys. he is told to segment similar ones. so based on features like shape,size,color,function etc he will try to make 3 groups say A,B,C and group them.

The word Supervise means you are giving supervision/instruction to machine to help it find answers. Once it learns instructions, it can easily predict for new case.

Unsupervised means there is no supervision or instruction how to find answers/labels and machine will use its intelligence to find some pattern in our data. Here it will not make prediction, it will just try to find clusters which has similar data.

<a class="btn btn-large btn-success" id="fire" href="http://twitter.github.io/bootstrap/examples/marketing-narrow.html#">Send Email</a>

You can put two figures inside one figure environment. For example:

\begin{figure}[p]
\centering
\includegraphics{fig1}
\caption{Caption 1}
\includegraphics{fig2}
\caption{Caption 2}
\end{figure}

Each caption will generate a separate figure number.

You can do it without writing any code at all :) You just need to set the default value for the column in the database. You can do this in your migrations. For example:

create_table :projects do |t|
  t.string :status, :null => false, :default => 'P'
  ...
  t.timestamps
end

Hope that helps.

If you don't mind introducing a dependency, CliWrap can simplify this for you:

using CliWrap;
using CliWrap.Buffered;

var result = await Cli.Wrap("target.exe")
   .WithArguments("arguments")
   .ExecuteBufferedAsync();

var stdout = result.StandardOutput;

Since Array(3) will create an un-iterable array, it must be populated to allow the usage of the map Array method. A way to "convert" is to destruct it inside Array-brackets, which "forces" the Array to be filled with undefined values, same as Array(N).fill(undefined)

<table>
    { [...Array(3)].map((_, index) => <tr key={index}/>) }
</table>

Another way would be via Array fill():

<table>
    { Array(3).fill(<tr/>) }
</table>

?? Problem with above example is the lack of key prop, which is a must.
(Using an iterator's index as key is not recommended)

Nested Nodes:

const tableSize = [3,4]
const Table = (
    <table>
        <tbody>
        { [...Array(tableSize[0])].map((tr, trIdx) => 
            <tr key={trIdx}> 
              { [...Array(tableSize[1])].map((a, tdIdx, arr) => 
                  <td key={trIdx + tdIdx}>
                  {arr.length * trIdx + tdIdx + 1}
                  </td>
               )}
            </tr>
        )}
        </tbody>
    </table>
);

ReactDOM.render(Table, document.querySelector('main'))

The mysql_* functions are deprecated and unsafe. The code in your question in vulnerable to injection attacks. It is highly recommended that you use the PDO extension instead, like so:

session_start();

$query = "SELECT 'id' FROM Users WHERE username = :name LIMIT 1";
$statement = $PDO->prepare($query);
$params = array(
    'name' => $_GET["username"]
);
$statement->execute($params);
$user_data = $statement->fetch();

$_SESSION['myid'] = $user_data['id'];

Where $PDO is your PDO object variable. See https://www.php.net/pdo_mysql for more information about PHP and PDO.

For extra help:

Here's a jumpstart on how to connect to your database using PDO:

$database_username = "YOUR_USERNAME";
$database_password = "YOUR_PASSWORD";
$database_info = "mysql:host=localhost;dbname=YOUR_DATABASE_NAME";
try
{
    $PDO = new PDO($database_info, $database_username, $database_password);
}
catch(PDOException $e)
{
    // Handle error here
}

            String[] fileData = extractor.getParagraphText();
            for (int i = 0; i < fileData.length; i++)
            {
                if (fileData[i] != null)
                    System.out.println(fileData[i]);
            }

Here is a ready to run source code for random number generator using c taken from this site: http://www.random-number.com/random-number-c/ . The implementation here is more general (a function that gets 3 parameters: min,max and number of random numbers to generate)

#include <time.h>
#include <stdlib.h>
#include <stdio.h>

// the random function
void RandomNumberGenerator(const int nMin, const int nMax, const int  nNumOfNumsToGenerate)
{
  int nRandonNumber = 0;
  for (int i = 0; i < nNumOfNumsToGenerate; i++)
  {
    nRandonNumber = rand()%(nMax-nMin) + nMin;
    printf("%d ", nRandonNumber);
  }
  printf("\n");
}

void main()
{
  srand(time(NULL));
  RandomNumberGenerator(1,70,5);
}

Set the image to be the background of a div, then set the background size to be half the width of the image.

<div class="myimage"></div>

Then in your css, if your image is 300px x 200px:

.myimage {
    background: url('images/myimage.png') no-repeat;
    background-size:150px;
    width:150px;
    height:100px;
}

Here is a list of what can be pickled. In particular, functions are only picklable if they are defined at the top-level of a module.

This piece of code:

import multiprocessing as mp

class Foo():
    @staticmethod
    def work(self):
        pass

if __name__ == '__main__':   
    pool = mp.Pool()
    foo = Foo()
    pool.apply_async(foo.work)
    pool.close()
    pool.join()

yields an error almost identical to the one you posted:

Exception in thread Thread-2:
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 552, in __bootstrap_inner
    self.run()
  File "/usr/lib/python2.7/threading.py", line 505, in run
    self.__target(*self.__args, **self.__kwargs)
  File "/usr/lib/python2.7/multiprocessing/pool.py", line 315, in _handle_tasks
    put(task)
PicklingError: Can't pickle <type 'function'>: attribute lookup __builtin__.function failed

The problem is that the pool methods all use a mp.SimpleQueue to pass tasks to the worker processes. Everything that goes through the mp.SimpleQueue must be pickable, and foo.work is not picklable since it is not defined at the top level of the module.

It can be fixed by defining a function at the top level, which calls foo.work():

def work(foo):
    foo.work()

pool.apply_async(work,args=(foo,))

Notice that foo is pickable, since Foo is defined at the top level and foo.__dict__ is picklable.

While you should keep your NuGet packages.config file, you should exclude the packages folder:

#NuGet
packages/

I typically don't store binaries, or anything generated from my source, in source control. There are differing opinions on this however. If it makes things easier for your build system, do it! I would however, argue that you are not versioning these dependencies, so they will just take up space in your repository. Storing the binaries in a central location, then relying on the packages.config file to indicate which version is needed is a better solution, in my opinion.

The solution given from "Nott Responding" seems to fire both events, click and dblclick when doubleclicked. However I think it points in the right direction.

I did a small change, this is the result :

$("#clickMe").click(function (e) {
    var $this = $(this);
    if ($this.hasClass('clicked')){
        $this.removeClass('clicked'); 
        alert("Double click");
        //here is your code for double click
    }else{
        $this.addClass('clicked');
        setTimeout(function() { 
            if ($this.hasClass('clicked')){
                $this.removeClass('clicked'); 
                alert("Just one click!");
                //your code for single click              
            }
        }, 500);          
    }
});

Try it

If you are using Java 8:

test.removeIf(t -> t.i == 1);

Java 8 has a removeIf method in the collection interface. For the ArrayList, it has an advanced implementation (order of n).

You can use StringBuilder:

    StringBuilder sb = new StringBuilder();
    sb.append('a');
    sb.append('b');
    sb.append('c');
    String str = sb.toString()

Or if you already have the characters, you can pass a character array to the String constructor:

String str = new String(new char[]{'a', 'b', 'c'});

Although this is not a general solution for every host, someone may find it useful. If you know where you are based (UK for me) then look at tianon's answer here.

FROM alpine:3.6
RUN apk add --no-cache tzdata
ENV TZ Europe/London

This is what I added to my Dockerfile ^ and the timezone problem was fixed.

If you want the caret down symbol, remove the "appearence: none" it implies to remove webkit and moz- as well from select in css.

Simpler way:

.then( resp=> {
  let resultFromDb= Object.values(resp)[0]
  console.log(resultFromDb)
}

In my example I received an object in response. When I use Object.values I have the value of the property as a response, however it comes inside an array, using [0] access the first index of this array, now i have the value to use it where I need it.

Only primitive types are supported for serialization by config parser. I would use JSON or YAML for that kind of requirement.

To augment LazyOne's answer, here is an annotated version of the answer.

<rewrite>
  <rules>
     <clear />
     <rule name="Redirect all requests to https" stopProcessing="true">
       <match url="(.*)" />
         <conditions logicalGrouping="MatchAll">
           <add input="{HTTPS}" pattern="off" ignoreCase="true" />
         </conditions>
         <action 
            type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" 
            redirectType="Permanent" appendQueryString="false" />
     </rule>
  </rules>
</rewrite>

Clear all the other rules that might already been defined on this server. Create a new rule, that we will name "Redirect all requests to https". After processing this rule, do not process any more rules! Match all incoming URLs. Then check whether all of these other conditions are true: HTTPS is turned OFF. Well, that's only one condition (but make sure it's true). If it is, send a 301 Permanent redirect back to the client at http://www.foobar.com/whatever?else=the#url-contains. Don't add the query string at the end of that, because it would duplicate the query string!

This is what the properties, attributes, and some of the values mean.

• clear removes all server rules that we might otherwise inherit.
• rule defines a rule.
  • name an arbitrary (though unique) name for the rule.
  • stopProcessing whether to forward the request immediately to the IIS request pipeline or first to process additional rules.
• match when to run this rule.
  • url a pattern against which to evaluate the URL
• conditions additional conditions about when to run this rule; conditions are processed only if there is first a match.
  • logicalGrouping whether all the conditions must be true (MatchAll) or any of the conditions must be true (MatchAny); similar to AND vs OR.
• add adds a condition that must be met.
  • input the input that a condition is evaluating; input can be server variables.
  • pattern the standard against which to evaluate the input.
  • ignoreCase whether capitalization matters or not.
• action what to do if the match and its conditions are all true.
  • type can generally be redirect (client-side) or rewrite (server-side).
  • url what to produce as a result of this rule; in this case, concatenate https:// with two server variables.
  • redirectType what HTTP redirect to use; this one is a 301 Permanent.
  • appendQueryString whether to add the query string at the end of the resultant url or not; in this case, we are setting it to false, because the {REQUEST_URI} already includes it.

The server variables are

• {HTTPS} which is either OFF or ON.
• {HTTP_HOST} is www.mysite.com, and
• {REQUEST_URI} includes the rest of the URI, e.g. /home?key=value
  • the browser handles the #fragment (see comment from LazyOne).

Try with this script, maybe will be useful:

SELECT CAST('TRUE' as bit) -- RETURN 1
SELECT CAST('FALSE' as bit) --RETURN 0

Anyway I always would use a value of 1 or 0 (not TRUE or FALSE). Following your example, the update script would be:

Update Table Set BitField=CAST('TRUE' as bit) Where ID=1

For a deep clone I use reflection as follows:

public List<T> CloneList<T>(IEnumerable<T> listToClone) {
    Type listType = listToClone.GetType();
    Type elementType = listType.GetGenericArguments()[0];
    List<T> listCopy = new List<T>();
    foreach (T item in listToClone) {
        object itemCopy = Activator.CreateInstance(elementType);
        foreach (PropertyInfo property in elementType.GetProperties()) {
            elementType.GetProperty(property.Name).SetValue(itemCopy, property.GetValue(item));
        }
        listCopy.Add((T)itemCopy);
    }
    return listCopy;
}

You can use List or IEnumerable interchangeably.

Question: Where is application-specific cache located on Android?

Answer: /data/data

For me, it worked very simply. At first, I made an empty data.frame, then in each iteration I added one column to it. Here is my code:

df <- data.frame(modelForOneIteration)
for(i in 1:10){
  model <- # some processing
  df[,i] = model
}

mmap is great if you have multiple processes accessing data in a read only fashion from the same file, which is common in the kind of server systems I write. mmap allows all those processes to share the same physical memory pages, saving a lot of memory.

mmap also allows the operating system to optimize paging operations. For example, consider two programs; program A which reads in a 1MB file into a buffer creating with malloc, and program B which mmaps the 1MB file into memory. If the operating system has to swap part of A's memory out, it must write the contents of the buffer to swap before it can reuse the memory. In B's case any unmodified mmap'd pages can be reused immediately because the OS knows how to restore them from the existing file they were mmap'd from. (The OS can detect which pages are unmodified by initially marking writable mmap'd pages as read only and catching seg faults, similar to Copy on Write strategy).

mmap is also useful for inter process communication. You can mmap a file as read / write in the processes that need to communicate and then use synchronization primitives in the mmap'd region (this is what the MAP_HASSEMAPHORE flag is for).

One place mmap can be awkward is if you need to work with very large files on a 32 bit machine. This is because mmap has to find a contiguous block of addresses in your process's address space that is large enough to fit the entire range of the file being mapped. This can become a problem if your address space becomes fragmented, where you might have 2 GB of address space free, but no individual range of it can fit a 1 GB file mapping. In this case you may have to map the file in smaller chunks than you would like to make it fit.

Another potential awkwardness with mmap as a replacement for read / write is that you have to start your mapping on offsets of the page size. If you just want to get some data at offset X you will need to fixup that offset so it's compatible with mmap.

And finally, read / write are the only way you can work with some types of files. mmap can't be used on things like pipes and ttys.

This was for my own project and I'm sharing it here too.

The difference between BCNF and 3NF

Using the BCNF definition

If and only if for every one of its dependencies X ? Y, at least one of the following conditions hold:

• X ? Y is a trivial functional dependency (Y ? X), or
• X is a super key for schema R

and the 3NF definition

If and only if, for each of its functional dependencies X ? A, at least one of the following conditions holds:

• X contains A (that is, X ? A is trivial functional dependency), or
• X is a superkey, or
• Every element of A-X, the set difference between A and X, is a prime attribute (i.e., each attribute in A-X is contained in some candidate key)

We see the following difference, in simple terms:

• In BCNF: Every partial key (prime attribute) can only depend on a superkey,

whereas

• In 3NF: A partial key (prime attribute) can also depend on an attribute that is not a superkey (i.e. another partial key/prime attribute or even a non-prime attribute).

Where

1. A prime attribute is an attribute found in a candidate key, and
2. A candidate key is a minimal superkey for that relation, and
3. A superkey is a set of attributes of a relation variable for which it holds that in all relations assigned to that variable, there are no two distinct tuples (rows) that have the same values for the attributes in this set.Equivalently a superkey can also be defined as a set of attributes of a relation schema upon which all attributes of the schema are functionally dependent. (A superkey always contains a candidate key/a candidate key is always a subset of a superkey. You can add any attribute in a relation to obtain one of the superkeys.)

That is, no partial subset (any non trivial subset except the full set) of a candidate key can be functionally dependent on anything other than a superkey.

A table/relation not in BCNF is subject to anomalies such as the update anomalies mentioned in the pizza example by another user. Unfortunately,

• BNCF cannot always be obtained, while
• 3NF can always be obtained.

3NF Versus BCNF Example

An example of the difference can currently be found at "3NF table not meeting BCNF (Boyce–Codd normal form)" on Wikipedia, where the following table meets 3NF but not BCNF because "Tennis Court" (a partial key/prime attribute) depends on "Rate Type" (a partial key/prime attribute that is not a superkey), which is a dependency we could determine by asking the clients of the database, the tennis club:

Today's Tennis Court Bookings (3NF, not BCNF)

Court   Start Time  End Time    Rate Type
------- ----------  --------    ---------
1       09:30       10:30       SAVER
1       11:00       12:00       SAVER
1       14:00       15:30       STANDARD
2       10:00       11:30       PREMIUM-B
2       11:30       13:30       PREMIUM-B
2       15:00       16:30       PREMIUM-A

The table's superkeys are:

S1 = {Court, Start Time}
S2 = {Court, End Time}
S3 = {Rate Type, Start Time}
S4 = {Rate Type, End Time}
S5 = {Court, Start Time, End Time}
S6 = {Rate Type, Start Time, End Time}
S7 = {Court, Rate Type, Start Time}
S8 = {Court, Rate Type, End Time}
ST = {Court, Rate Type, Start Time, End Time}, the trivial superkey

The 3NF problem: The partial key/prime attribute "Court" is dependent on something other than a superkey. Instead, it is dependent on the partial key/prime attribute "Rate Type". This means that the user must manually change the rate type if we upgrade a court, or manually change the court if wanting to apply a rate change.

• But what if the user upgrades the court but does not remember to increase the rate? Or what if the wrong rate type is applied to a court?

(In technical terms, we cannot guarantee that the "Rate Type" -> "Court" functional dependency will not be violated.)

The BCNF solution: If we want to place the above table in BCNF we can decompose the given relation/table into the following two relations/tables (assuming we know that the rate type is dependent on only the court and membership status, which we could discover by asking the clients of our database, the owners of the tennis club):

Rate Types (BCNF and the weaker 3NF, which is implied by BCNF)

Rate Type   Court   Member Flag
---------   -----   -----------
SAVER       1       Yes
STANDARD    1       No
PREMIUM-A   2       Yes
PREMIUM-B   2       No

Today's Tennis Court Bookings (BCNF and the weaker 3NF, which is implied by BCNF)

Member Flag     Court     Start Time   End Time
-----------     -----     ----------   --------
Yes             1         09:30        10:30
Yes             1         11:00        12:00
No              1         14:00        15:30
No              2         10:00        11:30
No              2         11:30        13:30
Yes             2         15:00        16:30

Problem Solved: Now if we upgrade the court we can guarantee the rate type will reflect this change, and we cannot charge the wrong price for a court.

(In technical terms, we can guarantee that the functional dependency "Rate Type" -> "Court" will not be violated.)

Where it is documented:

From the API documentation under the has_many association in "Module ActiveRecord::Associations::ClassMethods"

collection.build(attributes = {}, …) Returns one or more new objects of the collection type that have been instantiated with attributes and linked to this object through a foreign key, but have not yet been saved. Note: This only works if an associated object already exists, not if it‘s nil!

The answer to building in the opposite direction is a slightly altered syntax. In your example with the dogs,

Class Dog
   has_many :tags
   belongs_to :person
end

Class Person
  has_many :dogs
end

d = Dog.new
d.build_person(:attributes => "go", :here => "like normal")

or even

t = Tag.new
t.build_dog(:name => "Rover", :breed => "Maltese")

You can also use create_dog to have it saved instantly (much like the corresponding "create" method you can call on the collection)

How is rails smart enough? It's magic (or more accurately, I just don't know, would love to find out!)

Stopping Skype from using port 80: http://forum.skype.com/lofiversion/index.php/t15582.html

I linked to the login form by passing the current page as a GET parameter and then used 'next' to redirect to that page. Thanks!

By convention C strings are 'null-terminated'. That means that there's an extra byte at the end with the value of zero (0x00). Any function that does something with a string (like printf) will consider a string to end when it finds null. This also means that if your string is not null terminated, it will keep going until it finds a null character, which can produce some interesting results!

As the first item in your array is 0x00, it will be considered to be length zero (no characters).

If you defined your string to be:

char a[7]={0xdc,0x01,0x04,0x00};

e.g. null-terminated

then you can use strlen to measure the length of the string stored in the array.

sizeof measures the size of a type. It is not what you want. Also remember that the string in an array may be shorter than the size of the array.

In addition to the several programatic approaches discussed, another option is to redirect standard output from the shell. Here are several Unix and DOS examples.

I solved it by doing the following:

In Visual studio I went in Project -> Project Dependencies

I selected the XXX.Test solution and told it that it also depends on the XXX solution to make the post-build events in the XXX.Test solution not generate this error (exit with code 4).

If you combine time.sleep, threading.Thread, and sys.stdin.read you can easily wait for a specified amount of time for input and then continue, also this should be cross-platform compatible.

t = threading.Thread(target=sys.stdin.read(1) args=(1,))
t.start()
time.sleep(5)
t.join()

You could also place this into a function like so

def timed_getch(self, bytes=1, timeout=1):
    t = threading.Thread(target=sys.stdin.read, args=(bytes,))
    t.start()
    time.sleep(timeout)
    t.join()
    del t

Although this will not return anything so instead you should use the multiprocessing pool module you can find that here: how to get the return value from a thread in python?

An ioctl, which means "input-output control" is a kind of device-specific system call. There are only a few system calls in Linux (300-400), which are not enough to express all the unique functions devices may have. So a driver can define an ioctl which allows a userspace application to send it orders. However, ioctls are not very flexible and tend to get a bit cluttered (dozens of "magic numbers" which just work... or not), and can also be insecure, as you pass a buffer into the kernel - bad handling can break things easily.

An alternative is the sysfs interface, where you set up a file under /sys/ and read/write that to get information from and to the driver. An example of how to set this up:

static ssize_t mydrvr_version_show(struct device *dev,
        struct device_attribute *attr, char *buf)
{
    return sprintf(buf, "%s\n", DRIVER_RELEASE);
}

static DEVICE_ATTR(version, S_IRUGO, mydrvr_version_show, NULL);

And during driver setup:

device_create_file(dev, &dev_attr_version);

You would then have a file for your device in /sys/, for example, /sys/block/myblk/version for a block driver.

Another method for heavier use is netlink, which is an IPC (inter-process communication) method to talk to your driver over a BSD socket interface. This is used, for example, by the WiFi drivers. You then communicate with it from userspace using the libnl or libnl3 libraries.

    string ConvertStringArrayToString(string[] array)
    {
        //
        // Concatenate all the elements into a StringBuilder.
        //
        StringBuilder strinbuilder = new StringBuilder();
        foreach (string value in array)
        {
            strinbuilder.Append(value);
            strinbuilder.Append(' ');
        }
        return strinbuilder.ToString();
    }

For Development purpose you can just export the required tables data into a single HTML and make a direct search on it.
