Ok so this one works. Just in case anybody wants it, here's the version that works for me :)

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Base64;


public class HttpBasicAuth {

    public static void main(String[] args) {

        try {
            URL url = new URL ("http://ip:port/login");
            String encoding = Base64.getEncoder().encodeToString(("test1:test1").getBytes(?"UTF??-8"?));

            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setDoOutput(true);
            connection.setRequestProperty  ("Authorization", "Basic " + encoding);
            InputStream content = (InputStream)connection.getInputStream();
            BufferedReader in   = 
                new BufferedReader (new InputStreamReader (content));
            String line;
            while ((line = in.readLine()) != null) {
                System.out.println(line);
            }
        } catch(Exception e) {
            e.printStackTrace();
        }

    }

}

It seems there must be at least one local commit on the master branch to do:

git push -u origin master

So if you did git init . and then git remote add origin ..., you still need to do:

git add ...
git commit -m "..."

Since everyone has given you the JavaScript answer you've asked for, I'll throw in that the CSS property text-transform: capitalize will do exactly this.

I realize this might not be what you're asking for - you haven't given us any of the context in which you're running this - but if it's just for presentation, I'd definitely go with the CSS alternative.

Use the sizing utility classes...

• h-50 = height 50%
• h-100 = height 100%

When you send bytes from a buffer with a normal TCP socket, the send function returns the number of bytes of the buffer that were sent. If it is a non-blocking socket or a non-blocking send then the number of bytes sent may be less than the size of the buffer. If it is a blocking socket or blocking send, then the number returned will match the size of the buffer but the call may block. With WebSockets, the data that is passed to the send method is always either sent as a whole "message" or not at all. Also, browser WebSocket implementations do not block on the send call.

But there are more important differences on the receiving side of things. When the receiver does a recv (or read) on a TCP socket, there is no guarantee that the number of bytes returned corresponds to a single send (or write) on the sender side. It might be the same, it may be less (or zero) and it might even be more (in which case bytes from multiple send/writes are received). With WebSockets, the recipient of a message is event-driven (you generally register a message handler routine), and the data in the event is always the entire message that the other side sent.

Note that you can do message based communication using TCP sockets, but you need some extra layer/encapsulation that is adding framing/message boundary data to the messages so that the original messages can be re-assembled from the pieces. In fact, WebSockets is built on normal TCP sockets and uses frame headers that contains the size of each frame and indicate which frames are part of a message. The WebSocket API re-assembles the TCP chunks of data into frames which are assembled into messages before invoking the message event handler once per message.

• One simple way is replace \n(newline) with ","(double-quote comma double-quote) after this append double-quote in the start and end of file.

example:

      AliceBlue
      AntiqueWhite
      Aqua
      Aquamarine
      Beige

• Replcae \n with ","

    AliceBlue","AntiqueWhite","Aqua","Aquamarine","Beige
  

• Now append "(double-quote) at the start and end

   "AliceBlue","AntiqueWhite","Aqua","Aquamarine","Beige"
  

If your text contains blank lines in between you can use regular expression \n+ instead of \n

example:

      AliceBlue

      AntiqueWhite
      Aqua


      Aquamarine
      Beige

• Replcae \n+ with "," (in regex mode)

    AliceBlue","AntiqueWhite","Aqua","Aquamarine","Beige
  

• Now append "(double-quote) at the start and end

   "AliceBlue","AntiqueWhite","Aqua","Aquamarine","Beige"
  

I prefer this method for it's accuracy and succinctness:

var x
if (x === void 0) {
  console.log(`x is undefined`)
} else {
  console.log(`x is defined`)
}

As has been mentioned in other comments and answers, undefined isn't guaranteed to be undefined. Because it's not a keyword, it can be redefined as a variable in scopes other than the global scope. Here's little example that demonstrates this nuance:

var undefined = 'bar'
console.log(`In the global scope: ${undefined}`)

function foo() {
  var undefined = 'defined'
  var x
  if (x === undefined) {
    console.log(`x === undefined`)
  } else {
    console.log(`x !== undefined`)
  }
  if (x === void 0) {
    console.log(`x === void 0`)
  } else {
    console.log(`x !== void 0`)
  }
}

foo()

See void for compatibility (supported in IE5!?!! Wow!).

    returnValue = datetime.timedelta(minutes=5).total_seconds() + timestamp

The filter function wasn't working for me at all; maybe the more recent version of jquery doesn't perform as the version used in above code. Regardless; I used:

    var black = $('.black');
    var white = $('.white');

The selector will find every element classed under black or white. Button functions stay as stated above:

    $('#showBlackButton').click(function() {
           black.show();
           white.hide();
    });

    $('#showWhiteButton').click(function() {
           white.show();
           black.hide();
    });

Why not run something like Nexus, your own maven repo that you can upload 3rd party proprietary jar files, and also proxy other public repositories, to save on bandwith?

This also has some good reasons to run your own maven repository manager.

main_string = input()
sub_string = input()

count = counter = 0

for i in range(len(main_string)):
    if main_string[i] == sub_string[0]:
        k = i + 1
        for j in range(1, len(sub_string)):
            if k != len(main_string) and main_string[k] == sub_string[j]:
                count += 1
                k += 1
        if count == (len(sub_string) - 1):
            counter += 1
        count = 0

print(counter) 

This program counts the number of all substrings even if they are overlapped without the use of regex. But this is a naive implementation and for better results in worst case it is advised to go through either Suffix Tree, KMP and other string matching data structures and algorithms.

(There are good answers above regarding the SQL nature of your question, but this may also be relevant if you are new to PHP.)

Perhaps it is important to mention that PHP handles single and double quoted strings differently...

Single-quoted strings are 'literals' and are pretty much WYSIWYG strings. Double-quoted strings are interpreted by PHP for possible variable-substitution (backticks in PHP are not exactly strings; they execute a command in the shell and return the result).

Examples:

$foo = "bar";
echo 'there is a $foo'; // There is a $foo
echo "there is a $foo"; // There is a bar
echo `ls -l`; // ... a directory list

First To Enable ONCascade property:

1.Drop the existing foreign key constraint

2.add a new one with the ON DELETE CASCADE setting enabled

Ex:

IF EXISTS(SELECT 1 FROM sys.foreign_keys WHERE parent_object_id = OBJECT_ID(N'dbo.Response'))
 BEGIN 

ALTER TABLE [dbo].[Response] DROP CONSTRAINT [FK_Response_Request]  

ALTER TABLE [dbo].[Response] WITH CHECK ADD CONSTRAINT [FK_Response_Request]  FOREIGN KEY([RequestId])
REFERENCES [dbo].[Request] ([RequestId])
ON DELETE CASCADE
END

ELSE

 BEGIN 
 ALTER TABLE [dbo].[Response] WITH CHECK ADD CONSTRAINT [FK_Response_Request]  FOREIGN KEY([RequestId])
REFERENCES [dbo].[Request] ([RequestId])
ON DELETE CASCADE
END

Second To Disable ONCascade property:

1.Drop the existing foreign key constraint

2.Add a new one with the ON DELETE NO ACTION setting enabled

Ex:

IF EXISTS(SELECT 1 FROM sys.foreign_keys WHERE parent_object_id = OBJECT_ID(N'dbo.Response'))
 BEGIN 
ALTER TABLE [dbo].[Response] DROP CONSTRAINT [FK_Response_Request]  

ALTER TABLE [dbo].[Response] WITH CHECK ADD CONSTRAINT [FK_Response_Request]  FOREIGN KEY([RequestId])
REFERENCES [dbo].[Request] ([RequestId])
ON DELETE CASCADE
END

ELSE

 BEGIN 
 ALTER TABLE [dbo].[Response] WITH CHECK ADD CONSTRAINT [FK_Response_Request]  FOREIGN KEY([RequestId])
REFERENCES [dbo].[Request] ([RequestId])
ON DELETE NO ACTION 
END

Since C++17 you can use range-based for loops together with structured bindings for iterating over your map. This improves readability, as you reduce the amount of needed first and second members in your code:

std::map<std::string, std::pair<std::string, std::string>> myMap;
myMap["x"] = { "a", "b" };
myMap["y"] = { "c", "d" };

for (const auto &[k, v] : myMap)
    std::cout << "m[" << k << "] = (" << v.first << ", " << v.second << ") " << std::endl;

Output:

m[x] = (a, b)
m[y] = (c, d)

Several good solutions here. If you're still on Win2K and can't install anything on the remote computer, this also works:

Open the Computer Management Console (right click My Computer, choose Manage; open from Administrative Tools in the Start Menu; or open from the MMC using the snap-in).

Right click on your computer name and choose "Connect to Remote Computer"

Put in the computer name and credentials and you have full access to many admin functions including the services control panel.

Technically, ANSI should be the same as US-ASCII. It refers to the ANSI X3.4 standard, which is simply the ANSI organisation's ratified version of ASCII. Use of the top-bit-set characters is not defined in ASCII/ANSI as it is a 7-bit character set.

However years of misuse of the term by the DOS and subsequently Windows community has left its practical meaning as “the system codepage of whatever machine is being used”. The system codepage is also sometimes known as ‘mbcs’, since on East Asian systems that can be a multiple-byte-per-character encoding. Some code pages can even use top-bit-clear bytes as trailing bytes in a multibyte sequence, so it's not even strict compatible with plain ASCII... but even then, it's still called “ANSI”.

On US and Western European default settings, “ANSI” maps to Windows code page 1252. This is not the same as ISO-8859-1 (although it is quite similar). On other machines it could be anything else at all. This makes “ANSI” utterly useless as an external encoding identifier.

I always put my scripts in the header. My reasons:

1. I like to separate code and (static) text
2. I usually load my script from external sources
3. The same script is used from several pages, so it feels like an include file (which also goes in the header)

my opinion is that:

<link rel="stylesheet" href="{{ URL::to('/css/app.css') }}">

is the best method to route to your css files.

The URL::to() also works for js

An simpler alternative to Hokyo's "Non-Sequential enums" answer, based on using designators to instantiate the string array:

#define NAMES C(RED, 10)C(GREEN, 20)C(BLUE, 30)
#define C(k, v) k = v,
enum color { NAMES };
#undef C

#define C(k, v) [v] = #k,    
const char * const color_name[] = { NAMES };

This is the core idiom for reference-counted objects.

Reference-counting is a strong form of deterministic garbage collection- it ensures objects manage their OWN lifetime instead of relying on 'smart' pointers, etc. to do it for them. The underlying object is only ever accessed via "Reference" smart pointers, designed so that the pointers increment and decrement a member integer (the reference count) in the actual object.

When the last reference drops off the stack or is deleted, the reference count will go to zero. Your object's default behavior will then be a call to "delete this" to garbage collect- the libraries I write provide a protected virtual "CountIsZero" call in the base class so that you can override this behavior for things like caching.

The key to making this safe is not allowing users access to the CONSTRUCTOR of the object in question (make it protected), but instead making them call some static member- the FACTORY- like "static Reference CreateT(...)". That way you KNOW for sure that they're always built with ordinary "new" and that no raw pointer is ever available, so "delete this" won't ever blow up.

If you are using Java 6 or higher you can use wildcards of this form:

java -classpath ".;c:\mylibs\*;c:\extlibs\*" MyApp

If you would like to add all subdirectories: lib\a\, lib\b\, lib\c\, there is no mechanism for this in except:

java -classpath ".;c:\lib\a\*;c:\lib\b\*;c:\lib\c\*" MyApp

There is nothing like lib\*\* or lib\** wildcard for the kind of job you want to be done.

Intellij User, make sure you have 3 things,

1. Lombok dependency

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.8</version>
            <scope>provided</scope>
        </dependency>

2. IntelliJ plugin for Lombok

3. Lombok annotation, like @Getter @Setter (make sure it is coming from lombok and not from somewhere else)

and it should work.

This is definitely a bug.Laravel offers predefined code in routes/api.php

Route::middleware('auth:api')->get('/user', function (Request $request) { 
     return $request->user(); 
});

which is unabled to be processed by:

php artisan route:cache

This definitely should be fixed by Laravel team.(check the link),

simply if you want to fix it you should replace routes\api.php code with some thing like :

Route::middleware('auth:api')->get('/user', 'UserController@AuthRouteAPI');

and in UserController put this method:

 public function AuthRouteAPI(Request $request){
    return $request->user();
 }

Inspired by Nathanael Smith's answer and Eric Freese's comment, it could be as simple as:

var exec = require('child_process').exec;
exec('coffee -cw my_file.coffee').stdout.pipe(process.stdout);

The compatibility table given in the tensorflow site does not contain specific minor versions for cuda and cuDNN. However, if the specific versions are not met, there will be an error when you try to use tensorflow.

For tensorflow-gpu==1.12.0 and cuda==9.0, the compatible cuDNN version is 7.1.4, which can be downloaded from here after registration.

You can check your cuda version using
nvcc --version

cuDNN version using
cat /usr/include/cudnn.h | grep CUDNN_MAJOR -A 2

tensorflow-gpu version using
pip freeze | grep tensorflow-gpu

UPDATE: Since tensorflow 2.0, has been released, I will share the compatible cuda and cuDNN versions for it as well (for Ubuntu 18.04).

• tensorflow-gpu = 2.0.0
• cuda = 10.0
• cuDNN = 7.6.0

Actually, the entire approach would be cleaner if you only had to use one instance of StringBuffer, instead of creating one in every recursive call... I would go for:

private String getWhoozitYs(){
     StringBuffer sb = new StringBuffer();
     while (generator.nextBoolean()) {
         sb.append("y");
     }

     return sb.toString();
}

IF() in MySQL is a ternary function, not a control structure -- if the condition in the first argument is true, it returns the second argument; otherwise, it returns the third argument. There is no corresponding ELSEIF() function or END IF keyword.

The closest equivalent to what you've got would be something like:

IF(qty_1<='23', price,
  IF('23'>qty_1 && qty_2<='23', price_2,
    IF('23'>qty_2 && qty_3<='23', price_3,
      IF('23'>qty_3, price_4, 1)
    )
  )
)

The conditions don't all make sense to me (it looks as though some of them may be inadvertently reversed?), but without knowing what exactly you're trying to accomplish, it's hard for me to fix that.

I am so glad to solve this problem:

HttpPost httppost = new HttpPost(postData); 
CookieStore cookieStore = new BasicCookieStore(); 
BasicClientCookie cookie = new BasicClientCookie("JSESSIONID", getSessionId());

//cookie.setDomain("your domain");
cookie.setPath("/");

cookieStore.addCookie(cookie); 
client.setCookieStore(cookieStore); 
response = client.execute(httppost); 

So Easy!

Example URL: /rest/{keyword}

This URL is an example for path parameters. We can get this URL data by using @PathParam.

Example URL: /rest?keyword=java&limit=10

This URL is an example for query parameters. We can get this URL data by using @Queryparam.

If a dedicated script seems like too much overhead, you can spawn separate processes explicitly with sh -c. For example:

CMD sh -c 'mini_httpd -C /my/config -D &' \
 && ./content_computing_loop

I also just ran in to a similar problem, that is service apache2 reload fails but prints no useful information. This is because the script in /etc/init.d/apache (on Debian, at least) eats the output of the apache2ctl configtest command it runs to sanitize the Apache config.

An easy solution to get a more meaningful explanation for the failure is to run apache2ctl configtest again yourself, which will print the (hopefully useful) error messages to the console.

Really depends on your requirement, although lately I have seen a trend for classes with at least one bare constructor defined.

The upside of posting your parameters in via constructor is that you know those values can be relied on after instantiation. The downside is that you'll need to put more work in with any library that expects to be able to create objects with a bare constructor.

My personal preference is to go with a bare constructor and set any properties as part of the declaration.

Person p=new Person()
{
   Name = "Han Solo",
   Age = 39
};

This gets around the "class lacks bare constructor" problem, plus reduces maintenance ( I can set more things without changing the constructor ).

Use mktemp -d. It creates a temporary directory with a random name and makes sure that file doesn't already exist. You need to remember to delete the directory after using it though.

If you want to use fetch instead:

var myImage = document.querySelector('img');

fetch('flowers.jpg').then(function(response) {
  return response.blob();
}).then(function(myBlob) {
  var objectURL = URL.createObjectURL(myBlob);
  myImage.src = objectURL;
});

Angular 10 now I am using. After manually deleting all files and references then I re-run "ng serve", it worked.

Another extension method for Linq-to-Objects, without using GroupBy:

    /// <summary>
    /// Returns the set of items, made distinct by the selected value.
    /// </summary>
    /// <typeparam name="TSource">The type of the source.</typeparam>
    /// <typeparam name="TResult">The type of the result.</typeparam>
    /// <param name="source">The source collection.</param>
    /// <param name="selector">A function that selects a value to determine unique results.</param>
    /// <returns>IEnumerable&lt;TSource&gt;.</returns>
    public static IEnumerable<TSource> Distinct<TSource, TResult>(this IEnumerable<TSource> source, Func<TSource, TResult> selector)
    {
        HashSet<TResult> set = new HashSet<TResult>();

        foreach(var item in source)
        {
            var selectedValue = selector(item);

            if (set.Add(selectedValue))
                yield return item;
        }
    }

You can put the username() function in another page, and send the form to that page...

Are you mixing C and C++? One issue that can occur is that the declarations in the .h file for a .c file need to be surrounded by:

#if defined(__cplusplus)
  extern "C" {                 // Make sure we have C-declarations in C++ programs
#endif

and:

#if defined(__cplusplus)
  }
#endif

Note: if unable / unwilling to modify the .h file(s) in question, you can surround their inclusion with extern "C":

extern "C" {
#include <abc.h>
} //extern

JB hit the nail on the head. The only thing I can add is that Java 8 doesn't do pure parallel processing, it does paraquential. Yes I wrote the article and I've been doing F/J for thirty years so I do understand the issue.

The answer given by Simon works fine for me but you have to do it in the right sequence: First you have to be in the server that you want to insert data into which is [DATABASE.WINDOWS.NET].[basecampdev] in your case.

You can try to see if you can select some data out of the Invoice table to make sure you have access.

Select top 10 * from [DATABASE.WINDOWS.NET].[basecampdev].[dbo].[invoice]

Secondly, execute the query given by Simon in order to link to a different server. This time use the other server:

EXEC sp_addlinkedserver [BC1-PC]; -- this will create a link tempdb that you can access from where you are
GO
USE tempdb;
GO
CREATE SYNONYM MyInvoice FOR 
    [BC1-PC].testdabse.dbo.invoice; -- Make a copy of the table and data that you can use
GO

Now just do your insert statement.

INSERT INTO [DATABASE.WINDOWS.NET].[basecampdev].[dbo].[invoice]
       ([InvoiceNumber]
       ,[TotalAmount]

Worked for me perfectly as this:

Trims all selected cells. Beware of selecting full columns/rows :P.

Sub TrimSelected()    
Dim rng As Range, cell As Range    
Set rng = Selection   

For Each cell In rng    
cell = Trim(cell)   

Next cell    

End Sub

I used the Sebastien Horin function getIp and request()->ip() (at global request), because to localhost the getIp function return null:

$this->getIp() ?? request()->ip();

The getIp function:

public function getIp(){
foreach (array('HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED', 'REMOTE_ADDR') as $key){
    if (array_key_exists($key, $_SERVER) === true){
        foreach (explode(',', $_SERVER[$key]) as $ip){
            $ip = trim($ip); // just to be safe
            if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) !== false){
                return $ip;
            }
        }
    }
}

}

Same error occurs in localhost, i'm just changing the mysql port (8080 into localhost mysql port 5506). it works for me.

Try this:

var itemsInCart = from o in db.OrderLineItems
                  where o.OrderId == currentOrder.OrderId
                  select o.WishListItem.Price;

return Convert.ToDecimal(itemsInCart.Sum());

I think it's more simple!

I know the answer is in reply to a question asked 6 years ago ...

But I was looking for something similar for a few hours and then found out that: cut -c does exactly that, with an added bonus that you could also specify an offset.

cut -c 1-5 will return Hello and cut -c 7-11 will return world. No need for any other command

I have tried your example and it works just fine:

var app = 'AirFare';
var d1 = new Date();
var d2 = new Date();

$http({
    url: '/api/test',
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    data: {application: app, from: d1, to: d2}
});

Output:

Are you using the latest version of AngularJS?

You can't really. You'll have to have both the drop down, and the text box, and have them pick or fill in the form. Without javascript you could create a separate radio button set where they choose dropdown or text input, but this seems messy to me. With some javascript you could toggle disable one or the other depending on which one they choose, for instance, have an 'other' option in the dropdown that triggers the text field.

Seems your selector is wrong, try using:

a.button:hover{
     background: #383;
}

Your code

a.button a:hover

Means it is going to search for an a element inside a with class button.

You can use VBScript regular expression features using OLE Automation. This is way better than the overhead of creating and maintaining an assembly. Please make sure you go through the comments section to get a better modified version of the main one.

http://blogs.msdn.com/b/khen1234/archive/2005/05/11/416392.aspx

DECLARE @obj INT, @res INT, @match BIT;
DECLARE @pattern varchar(255) = '<your regex pattern goes here>';
DECLARE @matchstring varchar(8000) = '<string to search goes here>';
SET @match = 0;

-- Create a VB script component object
EXEC @res = sp_OACreate 'VBScript.RegExp', @obj OUT;

-- Apply/set the pattern to the RegEx object
EXEC @res = sp_OASetProperty @obj, 'Pattern', @pattern;

-- Set any other settings/properties here
EXEC @res = sp_OASetProperty @obj, 'IgnoreCase', 1;

-- Call the method 'Test' to find a match
EXEC @res = sp_OAMethod @obj, 'Test', @match OUT, @matchstring;

-- Don't forget to clean-up
EXEC @res = sp_OADestroy @obj;

If you get SQL Server blocked access to procedure 'sys.sp_OACreate'... error, use sp_reconfigure to enable Ole Automation Procedures. (Yes, unfortunately that is a server level change!)

More information about the Test method is available here

Happy coding

you also might want to take a look at SharpOS which is an operating system that they're writing in c#.

Mine also was funny. While copypasting " manifest.json" from the tutorial, i also managed to copy a leading space. Couldn't get why it's not finding it.

readable output!

echo json_encode($array);     //outputs--->    "name1":"value1",  "name2":"value2",  ...

OR

echo print_r($array, true);

I've made a gist with THE perfect method to manage fragment replacement and lifecycle.

It only replace the current fragment by a new one, if it's not the same and if it's not in backstack (in this case it will pop it).

It contain several option as if you want the fragment to be saved in backstack.

=> See Gist here

Using this and a single Activity, you may want to add this to your activity:

@Override
public void onBackPressed() {
    int fragments = getSupportFragmentManager().getBackStackEntryCount();
    if (fragments == 1) {
            finish();
            return;
    }

    super.onBackPressed();
}

It makes it easier for static typed languages (CLR) to interoperate with dynamic ones (python, ruby ...) running on the DLR (dynamic language runtime), see MSDN:

For example, you might use the following code to increment a counter in XML in C#.

Scriptobj.SetProperty("Count", ((int)GetProperty("Count")) + 1);

By using the DLR, you could use the following code instead for the same operation.

scriptobj.Count += 1;

MSDN lists these advantages:

• Simplifies Porting Dynamic Languages to the .NET Framework
• Enables Dynamic Features in Statically Typed Languages
• Provides Future Benefits of the DLR and .NET Framework
• Enables Sharing of Libraries and Objects
• Provides Fast Dynamic Dispatch and Invocation

See MSDN for more details.

This is the way how to check whether a given character is alphabet or not

public static void main(String[] args) {

    Scanner sc = new Scanner(System.in);
    char c = sc.next().charAt(0); 
    if((c >= 'a' && c <= 'z') || (c >= 'A' && c <= 'Z'))
         System.out.println(c + " is an alphabet.");
    else
        System.out.println(c + " is not an alphabet.");
}

I was also confused by this, and below is what I have learned.

When you clone a repository, for example from GitHub:

• origin is the alias for the URL from which you cloned the repository. Note that you can change this alias.

• There is one master branch in the remote repository (aliased by origin). There is also another master branch created locally.

Further information can be found from this SO question: Git branching: master vs. origin/master vs. remotes/origin/master

In latest version, mySQL uses auth_socket, so to login you've to know about the auto generated user credentials. or if you download binary version, while installation process, you can choose lagacy password.

To install SQL in linux debian versions

sudo apt install mysql-server

to know about the password

sudo cat /etc/mysql/debian.cnf

Now login

mysql -u debian-sys-maint -p

use the password from debian.cnf

How to see available user records:

USE mysql
SELECT User, Host, plugin FROM mysql.user;

Now you can create a new user. Use the below commands:

use mysql;
CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
GRANT ALL ON *.* TO 'username'@'localhost';
flush privileges;

To list the grants for the particular mysql user

SHOW GRANTS FOR 'username'@'localhost';

How to revoke all the grants for the particular mysql user

REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'username'@'localhost';

To delete/remove particular user from user account list

DROP USER 'username'@'localhost';

For more commands:

$ man 1 mysql

Please don't reset the password for root, instead create a new user and grant rights. This is the best practice.

For anyone looking to use this and keep the 'click' functionality (as John Landheer mentions in his comment), you can do it with just a couple of modifications:

Add a couple of globals:

var clickms = 100;
var lastTouchDown = -1;

Then modify the switch statement from the original to this:

var d = new Date();
switch(event.type)
{
    case "touchstart": type = "mousedown"; lastTouchDown = d.getTime(); break;
    case "touchmove": type="mousemove"; lastTouchDown = -1; break;        
    case "touchend": if(lastTouchDown > -1 && (d.getTime() - lastTouchDown) < clickms){lastTouchDown = -1; type="click"; break;} type="mouseup"; break;
    default: return;
}

You may want to adjust 'clickms' to your tastes. Basically it's just watching for a 'touchstart' followed quickly by a 'touchend' to simulate a click.

The other big difference is Abandon does not remove items immediately, but when it does then cleanup it does a loop over session items to check for STA COM objects it needs to handle specially. And this can be a problem.

Under high load it's possible for two (or more) requests to make it to the server for the same session (that is two requests with the same session cookie). Their execution will be serialized, but since Abandon doesn't clear out the items synchronously but rather sets a flag it's possible for both requests to run, and both requests to schedule a work item to clear out session "later". Both these work items can then run at the same time, and both are checking the session objects, and both are clearing out the array of objects, and what happens when you have two things iterating over a list and changing it?? Boom! And since this happens in a queueuserworkitem callback and is NOT done in a try/catch (thanks MS), it will bring down your entire app domain. Been there.

This is the error line:

if (called_from.equalsIgnoreCase("add")) {  --->38th error line

This means that called_from is null. Simple check if it is null above:

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

if(called_from == null) {
    called_from = "empty string";
}
if (called_from.equalsIgnoreCase("add")) {
    // do whatever
} else {
    // do whatever
}

That way, if called_from is null, it'll execute the else part of your if statement.

Request timed out means that the local host did not receive a response from the destination host, but it was able to reach it. Destination host unreachable means that there was no valid route to the requested host.

I'm not an expert, but I did a lot of looking to implement this for myself. I found something different, but modified it to accomplish this. It's really quite simple:

The function takes two arguments, a div containing only the words "show more" [or whatever] and a div containing the originally hidden text and the words "show less." The function displays the one div and hides the other.

NOTE: If more than one show/hide on page, assign different ids to divs Colors can be changed

<p>Here is text that is originally displayed</p>

<div id="div1">
<p style="color:red;" onclick="showFunction('div2','div1')">show more</p></div>
<div id="div2" style="display:none">

<p>Put expanded text here</p>

<p style="color:red;" onclick="showFunction('div1','div2')">show less</p></div>

<p>more text</p>

Here is the Script:

<script>
function showFunction(diva, divb) {
    var x = document.getElementById(diva);
    var y = document.getElementById(divb);
          x.style.display = 'block';
          y.style.display = 'none';
}
</script>

mod_php is a PHP interpreter.

From docs, one important catch of mod_php is,

"mod_php is not thread safe and forces you to stick with the prefork mpm (multi process, no threads), which is the slowest possible configuration"

I strongly suggest you to read this blog post which appeared on HackerNews recently: How HashMap works in Java

In short, the answer is

What will happen if two different HashMap key objects have same hashcode?

They will be stored in same bucket but no next node of linked list. And keys equals () method will be used to identify correct key value pair in HashMap.

The volatile keyword is used:

• to make non atomic 64-bit operations atomic: long and double. (all other, primitive accesses are already guaranteed to be atomic!)
• to make variable updates guaranteed to be seen by other threads + visibility effects: after writing to a volatile variable, all the variables that where visible before writing that variable become visible to another thread after reading the same volatile variable (happen-before ordering).

The java.util.concurrent.atomic.* classes are, according to the java docs:

A small toolkit of classes that support lock-free thread-safe programming on single variables. In essence, the classes in this package extend the notion of volatile values, fields, and array elements to those that also provide an atomic conditional update operation of the form:

boolean compareAndSet(expectedValue, updateValue);

The atomic classes are built around the atomic compareAndSet(...) function that maps to an atomic CPU instruction. The atomic classes introduce the happen-before ordering as the volatile variables do. (with one exception: weakCompareAndSet(...)).

From the java docs:

When a thread sees an update to an atomic variable caused by a weakCompareAndSet, it does not necessarily see updates to any other variables that occurred before the weakCompareAndSet.

To your question:

Does this mean that whosoever takes lock on it, that will be setting its value first. And in if meantime, some other thread comes up and read old value while first thread was changing its value, then doesn't new thread will read its old value?

You don't lock anything, what you are describing is a typical race condition that will happen eventually if threads access shared data without proper synchronization. As already mentioned declaring a variable volatile in this case will only ensure that other threads will see the change of the variable (the value will not be cached in a register of some cache that is only seen by one thread).

What is the difference between AtomicInteger and volatile int?

AtomicInteger provides atomic operations on an int with proper synchronization (eg. incrementAndGet(), getAndAdd(...), ...), volatile int will just ensure the visibility of the int to other threads.

There's no need to declare new variables in Python. If we're talking about variables in functions or modules, no declaration is needed. Just assign a value to a name where you need it: mymagic = "Magic". Variables in Python can hold values of any type, and you can't restrict that.

Your question specifically asks about classes, objects and instance variables though. The idiomatic way to create instance variables is in the __init__ method and nowhere else — while you could create new instance variables in other methods, or even in unrelated code, it's just a bad idea. It'll make your code hard to reason about or to maintain.

So for example:

class Thing(object):

    def __init__(self, magic):
        self.magic = magic

Easy. Now instances of this class have a magic attribute:

thingo = Thing("More magic")
# thingo.magic is now "More magic"

Creating variables in the namespace of the class itself leads to different behaviour altogether. It is functionally different, and you should only do it if you have a specific reason to. For example:

class Thing(object):

    magic = "Magic"

    def __init__(self):
        pass

Now try:

thingo = Thing()
Thing.magic = 1
# thingo.magic is now 1

Or:

class Thing(object):

    magic = ["More", "magic"]

    def __init__(self):
        pass

thing1 = Thing()
thing2 = Thing()
thing1.magic.append("here")
# thing1.magic AND thing2.magic is now ["More", "magic", "here"]

This is because the namespace of the class itself is different to the namespace of the objects created from it. I'll leave it to you to research that a bit more.

The take-home message is that idiomatic Python is to (a) initialise object attributes in your __init__ method, and (b) document the behaviour of your class as needed. You don't need to go to the trouble of full-blown Sphinx-level documentation for everything you ever write, but at least some comments about whatever details you or someone else might need to pick it up.

Just a note, file isn't supported in Python 3 and was removed. You can do the same with the open built-in function.

f = open('test.txt', 'w')
f.write('test\n')

This worked for me:

foreach (var item in FirmNameList){
    if (FirmNames != "")
    {
        FirmNames += ",\r\n"
    }

    FirmNames += item;
}

You cannot multiply an integer by a string. To be sure, you could try using the int (short for integer which means whole number) command, like this for example -

firstNumber = int(9)
secondNumber = int(1)
answer = (firstNumber*secondNumber)

Hope that helped :)

if you need to change your column output date format just use to_char this well get you a string, not a date.

I got same problem if i understand your question correctly, I want to know the last inserted id after every insert performance in SQLite operation. i tried the following statement:

select * from table_name order by id desc limit 1

The id is the first column and primary key of the table_name, the mentioned statement show me the record with the largest id.

But the premise is u never deleted any row so the numbers of id equal to the numbers of rows.

Mysqli makes use of object oriented programming. Try using this approach instead:

function dbCon() {
        if($mysqli = new mysqli('$hostname','$username','$password','$databasename')) return $mysqli; else return false;
}

if(!dbCon())
exit("<script language='javascript'>alert('Unable to connect to database')</script>");
else $con=dbCon();

if (isset($_GET['part'])){
    $partid = $_GET['part'];
    $sql = "SELECT * 
        FROM $usertable 
        WHERE PartNumber = $partid";

    $result=$con->query($sql_query);
    $row = $result->fetch_assoc();

    $partnumber = $partid;
    $nsn = $row["NSN"];
    $description = $row["Description"];
    $quantity = $row["Quantity"];
    $condition = $row["Conditio"];
}

Let me know if you have any questions, I could not test this code so you might need to tripple check it!

I would simply use:

stream.count()>0

                                FinalExpandCollapseAnimation.EXPAND,
                                SpecialOfferHeight, "linear", this);
                        findViewById(R.id.ll_specailoffer_show_hide)
                                .startAnimation(finalExpandCollapseAnimation);
                        ((View) findViewById(R.id.ll_specailoffer_show_hide).getParent()).invalidate();
                    }

You can use updateMany() methods of mongodb to update multiple document

Simple query is like this

db.collection.updateMany(filter, update, options)

For more doc of uppdateMany read here

As per your requirement the update code will be like this:

User.updateMany({"created": false}, {"$set":{"created": true}});

here you need to use $set because you just want to change created from true to false. For ref. If you want to change entire doc then you don't need to use $set

This question isn't thinking in terms of how canvas works. If you want a line break just simply adjust the coordinates of your next ctx.fillText.

ctx.fillText("line1", w,x,y,z)
ctx.fillText("line2", w,x,y,z+20)

Always try to use parametrized sql query to keep safe from malicious occurrence, so you could rearrange you code as below:

Also make sure that your table has column name matches to Name, PhoneNo ,Address.

using (SqlConnection connection = new SqlConnection(connectionString))
{
    SqlCommand cmd = new SqlCommand("INSERT INTO Data (Name, PhoneNo, Address) VALUES (@Name, @PhoneNo, @Address)");
    cmd.CommandType = CommandType.Text;
    cmd.Connection = connection;
    cmd.Parameters.AddWithValue("@Name", txtName.Text);
    cmd.Parameters.AddWithValue("@PhoneNo", txtPhone.Text);
    cmd.Parameters.AddWithValue("@Address", txtAddress.Text);
    connection.Open();
    cmd.ExecuteNonQuery();
}

FWIW, I had exactly the same question, but I could not find the answer here. It's probably not portable, but at least for gitolite, I can run the following to get what I want:

$ ssh [email protected] info
hello akim, this is gitolite 2.3-1 (Debian) running on git 1.7.10.4
the gitolite config gives you the following access:
     R   W     android
     R   W     bistro
     R   W     checkpn
...

find -regex ".*\.\(jpg\|gif\|png\|jpeg\)"

Exporting without default means it's a "named export". You can have multiple named exports in a single file. So if you do this,

class Template {}
class AnotherTemplate {}

export { Template, AnotherTemplate }

then you have to import these exports using their exact names. So to use these components in another file you'd have to do,

import {Template, AnotherTemplate} from './components/templates'

Alternatively if you export as the default export like this,

export default class Template {}

Then in another file you import the default export without using the {}, like this,

import Template from './components/templates'

There can only be one default export per file. In React it's a convention to export one component from a file, and to export it is as the default export.

You're free to rename the default export as you import it,

import TheTemplate from './components/templates'

And you can import default and named exports at the same time,

import Template,{AnotherTemplate} from './components/templates'

As per the documentation provided by PHP manual.

On each iteration, the value of the current element is assigned to $v and the internal
array pointer is advanced by one (so on the next iteration, you'll be looking at the next element).

So as per your first example:

$array = ['foo'=>1];
foreach($array as $k=>&$v)
{
   $array['bar']=2;
   echo($v);
}

$array have only single element, so as per the foreach execution, 1 assign to $v and it don't have any other element to move pointer

But in your second example:

$array = ['foo'=>1, 'bar'=>2];
foreach($array as $k=>&$v)
{
   $array['baz']=3;
   echo($v);
}

$array have two element, so now $array evaluate the zero indices and move the pointer by one. For first iteration of loop, added $array['baz']=3; as pass by reference.

In bootstrap 4 you can simply override default value of bootstrap variable $popover-max-width in your styles.scss file like so:

$popover-max-width: 300px;

@import "node_modules/bootstrap/scss/functions";
@import "node_modules/bootstrap/scss/variables";
@import "node_modules/bootstrap/scss/mixins";
@import "node_modules/bootstrap/scss/popover";

More on overriding bootstrap 4 defaults https://getbootstrap.com/docs/4.0/getting-started/theming/#variable-defaults

I was struggling and Found this Easy and Effective way from IntelliJ IDEA suggestion

<select id="country" formControlName="country"  >
  <option [defaultSelected]=true [value]="default" >{{default}}</option>
  <option *ngFor="let c of countries" [value]="c" >{{ c }}</option>
</select> 

And On your ts file assign the values

 countries = ['USA', 'UK', 'Canada'];
 default = 'UK'

Just make sure your formControlName accepts string, because you already assigned it as a string.

I have this method for deserializing an XML and converting the type:

public <T> Object deserialize(String xml, Class objClass ,TypeReference<T> typeReference ) throws IOException {
    XmlMapper xmlMapper = new XmlMapper();
    Object obj = xmlMapper.readValue(xml,objClass);
    return  xmlMapper.convertValue(obj,typeReference );   
}

and this is the call:

List<POJO> pojos = (List<POJO>) MyUtilClass.deserialize(xml, ArrayList.class,new TypeReference< List< POJO >>(){ });

In my case, it was because of low RAM memory, when a photo compression library was unable to process bigger photos.

This is not an error, it is a warning from your Microsoft compiler.

Select your project and click "Properties" in the context menu.

In the dialog, chose Configuration Properties -> C/C++ -> Preprocessor

In the field PreprocessorDefinitions add ;_CRT_SECURE_NO_WARNINGS to turn those warnings off.

Try getting the input stream from this you can then get the text data as so:-

    URL url;
    HttpURLConnection urlConnection = null;
    try {
        url = new URL("http://www.mysite.se/index.asp?data=99");

        urlConnection = (HttpURLConnection) url
                .openConnection();

        InputStream in = urlConnection.getInputStream();

        InputStreamReader isw = new InputStreamReader(in);

        int data = isw.read();
        while (data != -1) {
            char current = (char) data;
            data = isw.read();
            System.out.print(current);
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        if (urlConnection != null) {
            urlConnection.disconnect();
        }    
    }

You can probably use other inputstream readers such as buffered reader also.

The problem is that when you open the connection - it does not 'pull' any data.

Acording to http://dev.mysql.com/doc/refman/5.0/en/storage-requirements.html, the limit is L + 2 bytes, where L < 2^16, or 64k.

You shouldn't need to concern yourself with limiting it, it's automatically broken down into chunks that get added as the string grows, so it won't always blindly use 64k.

In my case when I use something like result.class.name I got something like Module1::class_name. But if we only want class_name, use

result.class.table_name.singularize

Late reply, but adding that Mongoose also has the concept of Subdocuments

With this syntax, you should be able to reference your userSchema as a type in your postSchema like so:

var userSchema = new Schema({
    twittername: String,
    twitterID: Number,
    displayName: String,
    profilePic: String,
});

var postSchema = new Schema({
    name: String,
    postedBy: userSchema,
    dateCreated: Date,
    comments: [{body:"string", by: mongoose.Schema.Types.ObjectId}],
});

Note the updated postedBy field with type userSchema.

This will embed the user object within the post, saving an extra lookup required by using a reference. Sometimes this could be preferable, other times the ref/populate route might be the way to go. Depends on what your application is doing.

In your case, ('AND' and 'OR' and 'NOT') evaluates to "NOT", which may or may not be in your list...

while 'AND' not in MyList and 'OR' not in MyList and 'NOT' not in MyList:
    print 'No Boolean Operator'

Try this

<div class="row">
    <div class="col-xs-2 col-xs-offset-5"></div>
</div>

You can use other col as well like col-md-2, etc.

Neither. You should NOT use a KeyLIstener.

Swing was designed to be used with Key Bindings. Read the section from the Swing tutorial on How to Use Key Bindings.

I was having same problem while installing tomcat in docker. I have solved by adding "^.*$" instead of "127.\d+.\d+.\d+|::1|0:0:0:0:0:0:0:1|123.123.123.123"

Restart the tomcat.

The issue can also be due to lack of hard drive space. The installation will succeed but on startup, oracle won't be able to create the required files and will fail with the same above error message.

First install without -g (global) on root. After try using -g (global) It worked for me.

The function here returns the parameter by name. With tiny changes you will be able to return base url, parameter or anchor.

function getUrlParameter(name) {
    var urlOld          = window.location.href.split('?');
    urlOld[1]           = urlOld[1] || '';
    var urlBase         = urlOld[0];
    var urlQuery        = urlOld[1].split('#');
    urlQuery[1]         = urlQuery[1] || '';
    var parametersString = urlQuery[0].split('&');
    if (parametersString.length === 1 && parametersString[0] === '') {
        parametersString = [];
    }
    // console.log(parametersString);
    var anchor          = urlQuery[1] || '';

    var urlParameters = {};
    jQuery.each(parametersString, function (idx, parameterString) {
        paramName   = parameterString.split('=')[0];
        paramValue  = parameterString.split('=')[1];
        urlParameters[paramName] = paramValue;
    });
    return urlParameters[name];
}

The AS in this case is an optional keyword defined in ANSI SQL 92 to define a <<correlation name> ,commonly known as alias for a table.

<table reference> ::=
            <table name> [ [ AS ] <correlation name>
                [ <left paren> <derived column list> <right paren> ] ]
          | <derived table> [ AS ] <correlation name>
                [ <left paren> <derived column list> <right paren> ]
          | <joined table>

     <derived table> ::= <table subquery>

     <derived column list> ::= <column name list>

     <column name list> ::=
          <column name> [ { <comma> <column name> }... ]


     Syntax Rules

     1) A <correlation name> immediately contained in a <table refer-
        ence> TR is exposed by TR. A <table name> immediately contained
        in a <table reference> TR is exposed by TR if and only if TR
        does not specify a <correlation name>.

It seems a best practice NOT to use the AS keyword for table aliases as it is not supported by a number of commonly used databases.

^\s*([0-9a-zA-Z]*)\s*$

or, if you want a minimum of one character:

^\s*([0-9a-zA-Z]+)\s*$

Square brackets indicate a set of characters. ^ is start of input. $ is end of input (or newline, depending on your options). \s is whitespace.

The whitespace before and after is optional.

The parentheses are the grouping operator to allow you to extract the information you want.

EDIT: removed my erroneous use of the \w character set.

I just had to implement a RESTfull api where I need to pass parameters. I did this by passing the parameters in the query string in the same style as described by Mark's first example "api/controller?start=date1&end=date2"

In the controller I used a tip from URL split in C#?

// uri: /api/courses
public IEnumerable<Course> Get()
{
    NameValueCollection nvc = HttpUtility.ParseQueryString(Request.RequestUri.Query);
    var system = nvc["System"];
    // BL comes here
    return _courses;
}

In my case I was calling the WebApi via Ajax looking like:

$.ajax({
        url: '/api/DbMetaData',
        type: 'GET',
        data: { system : 'My System',
                searchString: '123' },
        dataType: 'json',
        success: function (data) {
                  $.each(data, function (index, v) {
                  alert(index + ': ' + v.name);
                  });
         },
         statusCode: {
                  404: function () {
                       alert('Failed');
                       }
        }
   });

I hope this helps...

The cleanest way is use a function of janitor package that is built for exactly this purpose.

janitor::row_to_names(DF,1)

If you want to use any other row than the first one, pass it in the second parameter.

Instead, try:

var now = new Date();
current = new Date(now.getFullYear(), now.getMonth()+1, 1);

Basically you have two ways to iterate over all elements:

1. Using recursion (the most common way I think):

public static void main(String[] args) throws SAXException, IOException,
        ParserConfigurationException, TransformerException {

    DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory
        .newInstance();
    DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
    Document document = docBuilder.parse(new File("document.xml"));
    doSomething(document.getDocumentElement());
}

public static void doSomething(Node node) {
    // do something with the current node instead of System.out
    System.out.println(node.getNodeName());

    NodeList nodeList = node.getChildNodes();
    for (int i = 0; i < nodeList.getLength(); i++) {
        Node currentNode = nodeList.item(i);
        if (currentNode.getNodeType() == Node.ELEMENT_NODE) {
            //calls this method for all the children which is Element
            doSomething(currentNode);
        }
    }
}

2. Avoiding recursion using getElementsByTagName() method with * as parameter:

public static void main(String[] args) throws SAXException, IOException,
        ParserConfigurationException, TransformerException {

    DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory
            .newInstance();
    DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
    Document document = docBuilder.parse(new File("document.xml"));

    NodeList nodeList = document.getElementsByTagName("*");
    for (int i = 0; i < nodeList.getLength(); i++) {
        Node node = nodeList.item(i);
        if (node.getNodeType() == Node.ELEMENT_NODE) {
            // do something with the current element
            System.out.println(node.getNodeName());
        }
    }
}

I think these ways are both efficient.
Hope this helps.

I found out an easier way.

• go to File -> Settings -> Keymap
• Search for Execute Selection in Console and reassign it to a new shortcut, like Crl + Enter.

This is the same shortcut to the same action in Spyder and R-Studio.

Am I the only one who finds unwinding lists boring? ;-)

Let's try with objects. Real world example by the way.

Given: Object representing repetitive task. About important task fields: reminders are starting to ring at start and repeat every repeatPeriod repeatUnit(e.g. 5 HOURS) and there will be repeatCount reminders in total(including starting one).

Goal: achieve a list of task copies, one for each task reminder invocation.

List<Task> tasks =
            Arrays.asList(
                    new Task(
                            false,//completed sign
                            "My important task",//task name (text)
                            LocalDateTime.now().plus(2, ChronoUnit.DAYS),//first reminder(start)
                            true,//is task repetitive?
                            1,//reminder interval
                            ChronoUnit.DAYS,//interval unit
                            5//total number of reminders
                    )
            );

tasks.stream().flatMap(
        x -> LongStream.iterate(
                x.getStart().toEpochSecond(ZoneOffset.UTC),
                p -> (p + x.getRepeatPeriod()*x.getRepeatUnit().getDuration().getSeconds())
        ).limit(x.getRepeatCount()).boxed()
        .map( y -> new Task(x,LocalDateTime.ofEpochSecond(y,0,ZoneOffset.UTC)))
).forEach(System.out::println);

Output:

Task{completed=false, text='My important task', start=2014-10-01T21:35:24, repeat=false, repeatCount=0, repeatPeriod=0, repeatUnit=null}
Task{completed=false, text='My important task', start=2014-10-02T21:35:24, repeat=false, repeatCount=0, repeatPeriod=0, repeatUnit=null}
Task{completed=false, text='My important task', start=2014-10-03T21:35:24, repeat=false, repeatCount=0, repeatPeriod=0, repeatUnit=null}
Task{completed=false, text='My important task', start=2014-10-04T21:35:24, repeat=false, repeatCount=0, repeatPeriod=0, repeatUnit=null}
Task{completed=false, text='My important task', start=2014-10-05T21:35:24, repeat=false, repeatCount=0, repeatPeriod=0, repeatUnit=null}

P.S.: I would appreciate if someone suggested a simpler solution, I'm not a pro after all.

UPDATE: @RBz asked for detailed explanation so here it is. Basically flatMap puts all elements from streams inside another stream into output stream. A lot of streams here :). So, for each Task in initial stream lambda expression x -> LongStream.iterate... creates a stream of long values that represent task start moments. This stream is limited to x.getRepeatCount() instances. It's values start from x.getStart().toEpochSecond(ZoneOffset.UTC) and each next value is calculated using lambda p -> (p + x.getRepeatPeriod()*x.getRepeatUnit().getDuration().getSeconds(). boxed() returns the stream with each long value as a Long wrapper instance. Then each Long in that stream is mapped to new Task instance that is not repetitive anymore and contains exact execution time. This sample contains only one Task in input list. But imagine that you have a thousand. You will have then a stream of 1000 streams of Task objects. And what flatMap does here is putting all Tasks from all streams onto the same output stream. That's all as I understand it. Thank you for your question!

how can i return a array in a c++ method and how must i declare it? int[] test(void); ??

This sounds like a simple question, but in C++ you have quite a few options. Firstly, you should prefer...

• std::vector<>, which grows dynamically to however many elements you encounter at runtime, or

• std::array<> (introduced with C++11), which always stores a number of elements specified at compile time,

...as they manage memory for you, ensuring correct behaviour and simplifying things considerably:

std::vector<int> fn()
{
    std::vector<int> x;
    x.push_back(10);
    return x;
}

std::array<int, 2> fn2()  // C++11
{
    return {3, 4};
}

void caller()
{
    std::vector<int> a = fn();
    const std::vector<int>& b = fn(); // extend lifetime but read-only
                                      // b valid until scope exit/return

    std::array<int, 2> c = fn2();
    const std::array<int, 2>& d = fn2();
}

The practice of creating a const reference to the returned data can sometimes avoid a copy, but normally you can just rely on Return Value Optimisation, or - for vector but not array - move semantics (introduced with C++11).

If you really want to use an inbuilt array (as distinct from the Standard library class called array mentioned above), one way is for the caller to reserve space and tell the function to use it:

void fn(int x[], int n)
{
    for (int i = 0; i < n; ++i)
        x[i] = n;
}

void caller()
{
    // local space on the stack - destroyed when caller() returns
    int x[10];
    fn(x, sizeof x / sizeof x[0]);

    // or, use the heap, lives until delete[](p) called...
    int* p = new int[10];
    fn(p, 10);
}

Another option is to wrap the array in a structure, which - unlike raw arrays - are legal to return by value from a function:

struct X
{
    int x[10];
};

X fn()
{
    X x;
    x.x[0] = 10;
    // ...
    return x;
}

void caller()
{
    X x = fn();
}

Starting with the above, if you're stuck using C++03 you might want to generalise it into something closer to the C++11 std::array:

template <typename T, size_t N>
struct array
{
    T& operator[](size_t n) { return x[n]; }
    const T& operator[](size_t n) const { return x[n]; }
    size_t size() const { return N; }
    // iterators, constructors etc....
  private:
    T x[N];
};

Another option is to have the called function allocate memory on the heap:

int* fn()
{
    int* p = new int[2];
    p[0] = 0;
    p[1] = 1;
    return p;
}

void caller()
{
    int* p = fn();
    // use p...
    delete[] p;
}

To help simplify the management of heap objects, many C++ programmers use "smart pointers" that ensure deletion when the pointer(s) to the object leave their scopes. With C++11:

std::shared_ptr<int> p(new int[2], [](int* p) { delete[] p; } );
std::unique_ptr<int[]> p(new int[3]);

If you're stuck on C++03, the best option is to see if the boost library is available on your machine: it provides boost::shared_array.

Yet another option is to have some static memory reserved by fn(), though this is NOT THREAD SAFE, and means each call to fn() overwrites the data seen by anyone keeping pointers from previous calls. That said, it can be convenient (and fast) for simple single-threaded code.

int* fn(int n)
{
    static int x[2];  // clobbered by each call to fn()
    x[0] = n;
    x[1] = n + 1;
    return x;  // every call to fn() returns a pointer to the same static x memory
}

void caller()
{
    int* p = fn(3);
    // use p, hoping no other thread calls fn() meanwhile and clobbers the values...
    // no clean up necessary...
}

As mentioned elsewhere, you can just iterate over the array and it will produce all results in order across all dimensions. However, if you want to know the indices as well, then how about using this - http://blogs.msdn.com/b/ericlippert/archive/2010/06/28/computing-a-cartesian-product-with-linq.aspx

then doing something like:

var dimensionLengthRanges = Enumerable.Range(0, myArray.Rank).Select(x => Enumerable.Range(0, myArray.GetLength(x)));
var indicesCombinations = dimensionLengthRanges.CartesianProduct();

foreach (var indices in indicesCombinations)
{
    Console.WriteLine("[{0}] = {1}", string.Join(",", indices), myArray.GetValue(indices.ToArray()));
}

1. Open file with Xcode and press Command + Shift + J
2. Right click file name in left pane
3. Open as -> Hex

document.getElementById("aaa").href; //for example: http://example.com/sec/IF00.html

In environment.ts file set production to true

export const environment = {
  production: true
};

var result = from cx in CustomerList
         group cx by cx.GroupID into cxGroup
     orderby cxGroup.Key
     select cxGroup; 

foreach (var cxGroup in result) { 
Console.WriteLine(String.Format("GroupID = {0}", cxGroup.Key)); 
  foreach (var cx in cxGroup) { 
    Console.WriteLine(String.Format("\tUserID = {0}, UserName = {1}, GroupID = {2}", 
      new object[] { cx.ID, cx.Name, cx.GroupID })); 
  }
}

For small tables DELETE is often faster and needs less aggressive locking (for heavy concurrent load):

DELETE FROM tbl;

With no WHERE condition.

For medium or bigger tables, go with TRUNCATE tbl, like @Greg posted.

I recently had a need to do this. I came up with the following function that will allow bash to sleep forever without calling any external program:

snore()
{
    local IFS
    [[ -n "${_snore_fd:-}" ]] || { exec {_snore_fd}<> <(:); } 2>/dev/null ||
    {
        # workaround for MacOS and similar systems
        local fifo
        fifo=$(mktemp -u)
        mkfifo -m 700 "$fifo"
        exec {_snore_fd}<>"$fifo"
        rm "$fifo"
    }
    read ${1:+-t "$1"} -u $_snore_fd || :
}

NOTE: I previously posted a version of this that would open and close the file descriptor each time, but I found that on some systems doing this hundreds of times a second would eventually lock up. Thus the new solution keeps the file descriptor between calls to the function. Bash will clean it up on exit anyway.

This can be called just like /bin/sleep, and it will sleep for the requested time. Called without parameters, it will hang forever.

snore 0.1  # sleeps for 0.1 seconds
snore 10   # sleeps for 10 seconds
snore      # sleeps forever

There's a writeup with excessive details on my blog here

Before Android 4.4

What you are trying to do is simply not possible from an app (at least not on a non-rooted/non-modified device). The message "NFC tag type not supported" is displayed by the Android system (or more specifically the NFC system service) before and instead of dispatching the tag to your app. This means that the NFC system service filters MIFARE Classic tags and never notifies any app about them. Consequently, your app can't detect MIFARE Classic tags or circumvent that popup message.

On a rooted device, you may be able to bypass the message using either

1. Xposed to modify the behavior of the NFC service, or

2. the CSC (Consumer Software Customization) feature configuration files on the system partition (see /system/csc/. The NFC system service disables the popup and dispatches MIFARE Classic tags to apps if the CSC feature <CscFeature_NFC_EnableSecurityPromptPopup> is set to any value but "mifareclassic" or "all". For instance, you could use:

   <CscFeature_NFC_EnableSecurityPromptPopup>NONE</CscFeature_NFC_EnableSecurityPromptPopup>
   

   You could add this entry to, for instance, the file "/system/csc/others.xml" (within the section <FeatureSet> ... </FeatureSet> that already exists in that file).

Since, you asked for the Galaxy S6 (the question that you linked) as well: I have tested this method on the S4 when it came out. I have not verified if this still works in the latest firmware or on other devices (e.g. the S6).

Since Android 4.4

This is pure guessing, but according to this (link no longer available), it seems that some apps (e.g. NXP TagInfo) are capable of detecting MIFARE Classic tags on affected Samsung devices since Android 4.4. This might mean that foreground apps are capable of bypassing that popup using the reader-mode API (see NfcAdapter.enableReaderMode) possibly in combination with NfcAdapter.FLAG_READER_SKIP_NDEF_CHECK.

You can use :not(.class) selector as mentioned before.

If you care about Internet explorer compatibility I recommend you to use http://selectivizr.com/.

But remember to run it under apache otherwise you won't see the effect.

You can use this and it should be working --> You must use toList before making the new list using select:

db.Products
    .where(x=>x.CategoryID == categoryID).ToList()
    .select(x=>new Product { Name = p.Name}).ToList(); 

If you have control over the server, I would strongly recommend resizing the images server side with ImageMagik. Downloading large images and resizing them on the phone is a waste of many precious resources - bandwidth, battery and memory. All of which are scarce on phones.

The body's size is dynamic, it is only as large as the size of its contents. In the css file you could use: * {background-color: black} // All elements now have a black background.

or

html {background-color: black} // The page now have a black background, all elements remain the same.

Use WebClient.DownloadFile:

using (WebClient client = new WebClient())
{
    client.DownloadFile("http://csharpindepth.com/Reviews.aspx", 
                        @"c:\Users\Jon\Test\foo.txt");
}

I found a simpler solution with a dummy index file.

Create a Servlet (or use the one you wanted to respond to "/") which maps to "/index.html" (Solutions mentioned here use the mapping via XML, I used the 3.0 version with annotation @WebServlet) Then create a static (empty) file at the root of the static content named "index.html"

I was using Jetty, and what happened was that the server recognized the file instead of listing the directory but when asked for the resource, my Servlet took control instead. All other static content remained unaffected.

iOS 11 , Swift 4
And you can try this code:

if #available(iOS 11.0, *) {
   element.clipsToBounds = true
   element.layer.cornerRadius = CORNER_RADIUS
   element.layer.maskedCorners = [.layerMaxXMaxYCorner]
} else {
   // Fallback on earlier versions
}

And you can using this in table view cell.

EXPLAIN PLAN FOR

In SQL Developer, you don't have to use EXPLAIN PLAN FOR statement. Press F10 or click the Explain Plan icon.

It will be then displayed in the Explain Plan window.

If you are using SQL*Plus then use DBMS_XPLAN.

For example,

SQL> EXPLAIN PLAN FOR
  2  SELECT * FROM DUAL;

Explained.

SQL> SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);

You need to put the full path in the php ini when loading the mysql dll, i.e :-

extension=c:/php54/ext/php_mbstring.dll
extension=c:/php54/ext/php_mysql.dll

Then you don't need to move them to the windows folder.

You would use the command Mechanical snail listed. Notice the uppercase O. Full command line to use could be:

wget www.examplesite.com/textfile.txt --output-document=newfile.txt

or

wget www.examplesite.com/textfile.txt -O newfile.txt

Hope that helps.

Example:

function Foo () { console.log('Foo function'); }_x000D_
var Bar = function () { console.log('Bar function'); };_x000D_
var Abc = function Xyz() { console.log('Abc function'); };_x000D_
_x000D_
var f = new Foo();_x000D_
var b = new Bar();_x000D_
var a = new Abc();_x000D_
_x000D_
console.log('f', f.constructor.name); // -> "Foo"_x000D_
console.log('b', b.constructor.name); // -> "Function"_x000D_
console.log('a', a.constructor.name); // -> "Xyz"

In the following httpd.conf file, configure the ServerName properly.

/etc/httpd/conf/httpd.conf

Like below:

ServerName 127.0.0.1:80

or

ServerName sitename

This resolved similar issue I was facing.

Use read with a heredoc as shown below:

read -d '' sql << EOF
select c1, c2 from foo
where c1='something'
EOF

echo "$sql"

If you need to perform complex operation on URL, you can take a look to the jQuery url parser plugin.

Spinlock and Mutex synchronization mechanisms are very common today to be seen.

Let's think about Spinlock first.

Basically it is a busy waiting action, which means that we have to wait for a specified lock is released before we can proceed with the next action. Conceptually very simple, while implementing it is not on the case. For example: If the lock has not been released then the thread was swap-out and get into the sleep state, should do we deal with it? How to deal with synchronization locks when two threads simultaneously request access ?

Generally, the most intuitive idea is dealing with synchronization via a variable to protect the critical section. The concept of Mutex is similar, but they are still different. Focus on: CPU utilization. Spinlock consumes CPU time to wait for do the action, and therefore, we can sum up the difference between the two:

In homogeneous multi-core environments, if the time spend on critical section is small than use Spinlock, because we can reduce the context switch time. (Single-core comparison is not important, because some systems implementation Spinlock in the middle of the switch)

In Windows, using Spinlock will upgrade the thread to DISPATCH_LEVEL, which in some cases may be not allowed, so this time we had to use a Mutex (APC_LEVEL).

Here's another way of doing the code above using the openpyxl module that's compatible with xlsx. From what I've seen so far, it also keeps formatting.

from openpyxl import load_workbook
wb = load_workbook('names.xlsx')
ws = wb['SheetName']
ws['A1'] = 'A1'
wb.save('names.xlsx')

All the answers talk about horizontal align.

For vertical aligning multiple content elements, take a look at this approach:

<div style="display: flex; align-items: center; width: 200px; height: 140px; padding: 10px 40px; border: solid 1px black;">_x000D_
    <div>_x000D_
        <p>Paragraph #1</p>_x000D_
        <p>Paragraph #2</p>_x000D_
    </div>_x000D_
</div>

You can use the filter function to apply more complicated regex matching.

Here's an example which would just match the first three divs:

$('div')_x000D_
  .filter(function() {_x000D_
    return this.id.match(/abc+d/);_x000D_
  })_x000D_
  .html("Matched!");

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
<div id="abcd">Not matched</div>_x000D_
<div id="abccd">Not matched</div>_x000D_
<div id="abcccd">Not matched</div>_x000D_
<div id="abd">Not matched</div>

Another way to use itertools.ifilter. This checks truthiness and process (using lambda)

Sample-

for x in itertools.ifilter(lambda x: x[2] == 0, my_list):
    print x

Mesos and Kubernetes both are container orchestration tools.

When you say "Google Kubernetes"?

Google Kubernetes Engine provides a managed environment for deploying, managing, and scaling your containerized applications using Google infrastructure.

Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications.” Kubernetes was built by Google based on their experience running containers in production over the last decade.

The major components in a Kubernetes cluster are:

pods — a way to group containers together replication controllers — a way to handle the lifecycle of containers labels — a way to find and query containers, and services — a set of containers performing a common function

Mesos is an open-source cluster management project by Apache, designed to scale to very large clusters, from hundreds to thousands of hosts. Mesos supports diverse kinds of workloads such as Hadoop tasks, cloud native applications etc. It gives you the ability to run both containerized, and non-containerized workloads in a distributed manner.

It was initially written as a research project at Berkeley and was later adopted by Twitter as an answer to Google’s Borg (Kubernetes’ predecessor). To combat its high degree of complexity (Mesos is super complicated and hard to manage!), Mesosphere came into the picture to try and make Mesos into something regular human beings can use.

Mesosphere supplied the superb Marathon “plugin” to Mesos, which provides users with an easy way to manage container orchestration over Mesos.

In mid-2016, DC/OS (Data Center Operating System) — an open source project backed by Mesosphere — was introduced, which simplifies Mesos even further and allows you to deploy your own Mesos cluster, with Marathon, in a matter of minutes.

Now, if we compare kubernetes and Mesos(DC/OS)

kubernetes is a cluster manager for containers while mesos is a distributed system kernel that will make your cluster look like one giant computer system to all supported frameworks and apps that are built to be run on mesos.

Mesos was born for a world where you own a lot of physical resources to create a big static computing cluster. The great thing about it is that lots of modern scalable data processing application runs very well on Mesos (Hadoop, Kafka, Spark) and it is nice because you can run them all on the same basic resource pool, along with your new age container packaged apps.

Mesos cluster also runs alongside the Marathon cluster. Marathon, created by Mesosphere, is designed to start, monitor and scale long-running applications, including cloud native apps. Clients interact with Marathon through a REST API.

Also, a point to be noted is that you can actually run Kubernetes on top of DC/OS and schedule containers with it instead of using Marathon. This implies the biggest difference of all — DC/OS, as it name suggests, is more similar to an operating system rather than an orchestration framework. You can run non-containerized, stateful workloads on it. Container scheduling is handled by the Marathon.

In case someone is looking for a solution for Bootstrap v2.X.X here. I am leaving the solution I was using. This is not fully tested on all browsers however it could be a good start.

1) make sure the media attribute of bootstrap-responsive.css is screen.

<link href="/css/bootstrap-responsive.min.css" rel="stylesheet" media="screen" />

2) create a print.css and make sure its media attribute print

<link href="/css/print.css" rel="stylesheet" media="print" />

3) inside print.css, add the "width" of your website in html & body

html, 
body {
    width: 1200px !important;
}

4.) reproduce the necessary media query classes in print.css because they were inside bootstrap-responsive.css and we have disabled it when printing.

.hidden{display:none;visibility:hidden}
.visible-phone{display:none!important}
.visible-tablet{display:none!important}
.hidden-desktop{display:none!important}
.visible-desktop{display:inherit!important}

Here is full version of print.css:

html, 
body {
    width: 1200px !important;
}

.hidden{display:none;visibility:hidden}
.visible-phone{display:none!important}
.visible-tablet{display:none!important}
.hidden-desktop{display:none!important}
.visible-desktop{display:inherit!important}

After much fighting, this is what worked for me:

.pre {
    font-weight: 500;
    font-family: Courier New, monospace;
    white-space: pre-wrap;
    word-wrap: break-word;
    word-break: break-all;
    -webkit-hyphens: auto;
    -moz-hyphens: auto;
    hyphens: auto;
}

Works in the latest versions of Chrome, Firefox and Opera.

Note that I excluded many of the white-space properties the others suggested -- that actually broke the pre indentation for me.

No, how you are doing it is correct.

Cache-Control: private

Indicates that all or part of the response message is intended for a single user and MUST NOT be cached by a shared cache, such as a proxy server.

From RFC2616 section 14.9.1

If you're making a dictionary only to make a list of tuples, as creating dicts like you are may be a pain, you might look into using zip()

Its especialy useful if you've got one heading, and multiple rows. For instance if I assume that you want Olympics stats for countries:

headers = ['Capital', 'Food', 'Year']
countries = [
    ['London', 'Fish & Chips', '2012'],
    ['Beijing', 'Noodles', '2008'],
]

for olympics in countries:
    print zip(headers, olympics)

gives

[('Capital', 'London'), ('Food', 'Fish & Chips'), ('Year', '2012')]
[('Capital', 'Beijing'), ('Food', 'Noodles'), ('Year', '2008')]

Don't know if thats the end goal, and my be off topic, but it could be something to keep in mind.

The link you are referring to seems to work with strings generated at runtime. The strings from strings.xml are not created at runtime. You can get them via

String mystring = getResources().getString(R.string.mystring);

getResources() is a method of the Context class. If you are inside a Activity or a Service (which extend Context) you can use it like in this snippet.

Also note that the whole language dependency can be taken care of by the android framework. Simply create different folders for each language. If english is your default language, just put the english strings into res/values/strings.xml. Then create a new folder values-ru and put the russian strings with identical names into res/values-ru/strings.xml. From this point on android selects the correct one depending on the device locale for you, either when you call getString() or when referencing strings in XML via @string/mystring. The ones from res/values/strings.xml are the fallback ones, if you don't have a folder covering the users locale, this one will be used as default values.

See Localization and Providing Resources for more information.

Increase your CSS Specificity

Example:

.parent-class .flex-control-thumbs li {
  width: auto;
  float: none;
}

Demo:

.sample-class {
  height: 50px;
  width: 50px;
  background: red;
}

.inner-page .sample-class {
  background: green;
}

<div>
  <div class="sample-class"></div>
</div>

<div class="inner-page">
  <div class="sample-class"></div>
</div>

The wb indicates that the file is opened for writing in binary mode.

When writing in binary mode, Python makes no changes to data as it is written to the file. In text mode (when the b is excluded as in just w or when you specify text mode with wt), however, Python will encode the text based on the default text encoding. Additionally, Python will convert line endings (\n) to whatever the platform-specific line ending is, which would corrupt a binary file like an exe or png file.

Text mode should therefore be used when writing text files (whether using plain text or a text-based format like CSV), while binary mode must be used when writing non-text files like images.

If your code must run under Python2 and Python3, use the 2to3 six library like this:

import six

six.next(g)  # on PY2K: 'g.next()' and onPY3K: 'next(g)'

Whenever you are using require_once() can be use in a file to include another file when you need the called file only a single time in the current file. Here in the example I have an test1.php.

<?php  
echo "today is:".date("Y-m-d");  
?>  

and in another file that I have named test2.php

<?php  
require_once('test1.php');  
require_once('test1.php');  
?>

as you are watching the m requiring the the test1 file twice but the file will include the test1 once and for calling at the second time this will be ignored. And without halting will display the output a single time.

Whenever you are using 'include_once()` can be used in a file to include another file when you need the called file more than once in the current file. Here in the example I have a file named test3.php.

<?php  
echo "today is:".date("Y-m-d");  
?> 

And in another file that I have named test4.php

<?php  
include_once('test3.php');  
include_once('test3.php');  
?>

as you are watching the m including the test3 file will include the file a single time but halt the further execution.

use this css for height

height: calc(100vh) !important;

This will make the video to have 100% vertical height available.

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

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

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

The options discussed above won't work because they are not part of the CSS specification (it is jQuery extension). Having spent 2-3 days digging around for information, I found that the only way to select the Text of the selected option from the drop down is:

{ $("select", id:"Some_ID").find("option[selected='selected']")}

Refer to additional notes below: Because :selected is a jQuery extension and not part of the CSS specification, queries using :selected cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :selected to select elements, first select the elements using a pure CSS selector, then use .filter(":selected"). (copied from: http://api.jquery.com/selected-selector/)

In SQL, this problem could be solved by several methods:

select * from df1 where exists (select * from df2 where df2.user_id = df1.user_id)
union all
select * from df2 where exists (select * from df1 where df1.user_id = df2.user_id)

or join and then unpivot (possible in SQL server)

select
    df1.user_id,
    c.rating
from df1
    inner join df2 on df2.user_i = df1.user_id
    outer apply (
        select df1.rating union all
        select df2.rating
    ) as c

Second one could be written in pandas with something like:

>>> df1 = pd.DataFrame({"user_id":[1,2,3], "rating":[10, 15, 20]})
>>> df2 = pd.DataFrame({"user_id":[3,4,5], "rating":[30, 35, 40]})
>>>
>>> df4 = df[['user_id', 'rating_1']].rename(columns={'rating_1':'rating'})
>>> df = pd.merge(df1, df2, on='user_id', suffixes=['_1', '_2'])
>>> df3 = df[['user_id', 'rating_1']].rename(columns={'rating_1':'rating'})
>>> df4 = df[['user_id', 'rating_2']].rename(columns={'rating_2':'rating'})
>>> pd.concat([df3, df4], axis=0)
   user_id  rating
0        3      20
0        3      30

To get the list of the enum values you have to use:

enum AnimalEnum {
  DOG = "dog", 
  CAT = "cat", 
  MOUSE = "mouse"
}

Object.values(AnimalEnum);

It's possible that you have a problem with two filenames differing only by uppercase. If you ran into this problem, creating another working copy directory does not solve the problem.

Current Windows (i.e. crappy) filesystems simply do not grok the difference between Filename and FILEname. You have two possible fixes:

1. Check out at platform with a real filesystem (Unix-based), rename the file, and commit changes.
2. When you are stocked to Windows you can rename files in the Eclipse SVN repository browser which does recognise the difference and rename the file there.
3. You can rename the problematic files also remotely from any command-line SVN client using svn rename -m "broken filename case" http://server/repo/FILEname http://server/repo/filename

Your comparison function is not even wrong.

Its arguments should be the type stored in the range, i.e. std::pair<K,V>, not const void*.

It should return bool not a positive or negative value. Both (bool)1 and (bool)-1 are true so your function says every object is ordered before every other object, which is clearly impossible.

You need to model the less-than operator, not strcmp or memcmp style comparisons.

See StrictWeakOrdering which describes the properties the function must meet.

Just complementing Hovercraft Full Of Eels's solution:

I reworked his code, tweaked it a bit, adding a grid, axis labels and now the Y-axis goes from the minimum value present up to the maximum value. I planned on adding a couple of getters/setters but I didn't need them, you can add them if you want.

It looks like this:

You need to give a function to be called after the time delay as the second argument to after:

after(delay_ms, callback=None, *args)

Registers an alarm callback that is called after a given time.

So what you really want to do is this:

tiles_letter = ['a', 'b', 'c', 'd', 'e']

def add_letter():
    rand = random.choice(tiles_letter)
    tile_frame = Label(frame, text=rand)
    tile_frame.pack()
    root.after(500, add_letter)
    tiles_letter.remove(rand)  # remove that tile from list of tiles


root.after(0, add_letter)  # add_letter will run as soon as the mainloop starts.
root.mainloop()

You also need to schedule the function to be called again by repeating the call to after inside the callback function, since after only executes the given function once. This is also noted in the documentation:

The callback is only called once for each call to this method. To keep calling the callback, you need to reregister the callback inside itself

Note that your example will throw an exception as soon as you've exhausted all the entries in tiles_letter, so you need to change your logic to handle that case whichever way you want. The simplest thing would be to add a check at the beginning of add_letter to make sure the list isn't empty, and just return if it is:

def add_letter():
    if not tiles_letter:
        return
    rand = random.choice(tiles_letter)
    tile_frame = Label(frame, text=rand)
    tile_frame.pack()
    root.after(500, add_letter)
    tiles_letter.remove(rand)  # remove that tile from list of tiles

Live-Demo: repl.it

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

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

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

Here's another approach, in case you want split a string with a delimiter.

import pyspark.sql.functions as f

df = spark.createDataFrame([("1:a:2001",),("2:b:2002",),("3:c:2003",)],["value"])
df.show()
+--------+
|   value|
+--------+
|1:a:2001|
|2:b:2002|
|3:c:2003|
+--------+

df_split = df.select(f.split(df.value,":")).rdd.flatMap(
              lambda x: x).toDF(schema=["col1","col2","col3"])

df_split.show()
+----+----+----+
|col1|col2|col3|
+----+----+----+
|   1|   a|2001|
|   2|   b|2002|
|   3|   c|2003|
+----+----+----+

I don't think this transition back and forth to RDDs is going to slow you down... Also don't worry about last schema specification: it's optional, you can avoid it generalizing the solution to data with unknown column size.

You cannot define a variable of an incomplete type. You need to bring the whole definition of Cat into scope before you can create the local variable in main. I recommend that you move the definition of the type Cat to a header and include it from the translation unit that has main.

x = [i for i in x if len(i)==2]

From Java 1.5 it's always a good Idea to consider java.util.concurrent package. They are the state of the art locking mechanism in java right now. The synchronize mechanism is more heavyweight that the java.util.concurrent classes.

The example would look something like this:

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

public class Sample {

    private final Lock lock = new ReentrantLock();

    private String message = null;

    public void newmsg(String msg) {
        lock.lock();
        try {
            message = msg;
        } finally {
            lock.unlock();
        }
    }

    public String getmsg() {
        lock.lock();
        try {
            String temp = message;
            message = null;
            return temp;
        } finally {
            lock.unlock();
        }
    }
}

$observe() is a method on the Attributes object, and as such, it can only be used to observe/watch the value change of a DOM attribute. It is only used/called inside directives. Use $observe when you need to observe/watch a DOM attribute that contains interpolation (i.e., {{}}'s).
E.g., attr1="Name: {{name}}", then in a directive: attrs.$observe('attr1', ...).
(If you try scope.$watch(attrs.attr1, ...) it won't work because of the {{}}s -- you'll get undefined.) Use $watch for everything else.

$watch() is more complicated. It can observe/watch an "expression", where the expression can be either a function or a string. If the expression is a string, it is $parse'd (i.e., evaluated as an Angular expression) into a function. (It is this function that is called every digest cycle.) The string expression can not contain {{}}'s. $watch is a method on the Scope object, so it can be used/called wherever you have access to a scope object, hence in

• a controller -- any controller -- one created via ng-view, ng-controller, or a directive controller
• a linking function in a directive, since this has access to a scope as well

Because strings are evaluated as Angular expressions, $watch is often used when you want to observe/watch a model/scope property. E.g., attr1="myModel.some_prop", then in a controller or link function: scope.$watch('myModel.some_prop', ...) or scope.$watch(attrs.attr1, ...) (or scope.$watch(attrs['attr1'], ...)).
(If you try attrs.$observe('attr1') you'll get the string myModel.some_prop, which is probably not what you want.)

As discussed in comments on @PrimosK's answer, all $observes and $watches are checked every digest cycle.

Directives with isolate scopes are more complicated. If the '@' syntax is used, you can $observe or $watch a DOM attribute that contains interpolation (i.e., {{}}'s). (The reason it works with $watch is because the '@' syntax does the interpolation for us, hence $watch sees a string without {{}}'s.) To make it easier to remember which to use when, I suggest using $observe for this case also.

To help test all of this, I wrote a Plunker that defines two directives. One (d1) does not create a new scope, the other (d2) creates an isolate scope. Each directive has the same six attributes. Each attribute is both $observe'd and $watch'ed.

<div d1 attr1="{{prop1}}-test" attr2="prop2" attr3="33" attr4="'a_string'"
        attr5="a_string" attr6="{{1+aNumber}}"></div>

Look at the console log to see the differences between $observe and $watch in the linking function. Then click the link and see which $observes and $watches are triggered by the property changes made by the click handler.

Notice that when the link function runs, any attributes that contain {{}}'s are not evaluated yet (so if you try to examine the attributes, you'll get undefined). The only way to see the interpolated values is to use $observe (or $watch if using an isolate scope with '@'). Therefore, getting the values of these attributes is an asynchronous operation. (And this is why we need the $observe and $watch functions.)

Sometimes you don't need $observe or $watch. E.g., if your attribute contains a number or a boolean (not a string), just evaluate it once: attr1="22", then in, say, your linking function: var count = scope.$eval(attrs.attr1). If it is just a constant string – attr1="my string" – then just use attrs.attr1 in your directive (no need for $eval()).

See also Vojta's google group post about $watch expressions.

What you're looking at is called a Ternary Operator, and you can find the PHP implementation here. It's an if else statement.

if (isset($_GET['something']) == true) {
    thing = isset($_GET['something']);
} else {
    thing = "";
}

You can do

$('.page-address-edit').addClass('test1 test2');

More here:

More than one class may be added at a time, separated by a space, to the set of matched elements, like so:

$("p").addClass("myClass yourClass");

An answer to Kandha problem above :

It throws the "java.io.IOException service not available" i already gave those permission and include the library...i can get map view...it throws that IOException at geocoder...

I just added a catch IOException after the try and it solved the problem

    catch(IOException ioEx){
        return null;
    }

Adding to above answers, take a look at following. AppointmentForm's date column is annotated with couple of annotations. By having @Valid annotation that triggers validations on the AppointmentForm (in this case @NotNull and @Future). These annotations could come from different JSR-303 providers (e.g, Hibernate, Spring..etc).

    @RequestMapping(value = "/appointments", method = RequestMethod.POST)
    public String add(@Valid AppointmentForm form, BindingResult result) {
        ....
    }

    static class AppointmentForm {

        @NotNull @Future
        private Date date;
    }

1)Yes it is, when there is style then it is styling your code(css).2) is belong to html it is like a container that keep your css.

I used the following for a drawable image with a border.

First make a .xml file with this code in drawable folder:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape android:shape="oval">
        <solid android:color="@color/orange"/>
    </shape>
</item>
<item
    android:top="2dp"
    android:bottom="2dp"
    android:left="2dp"
    android:right="2dp">
    <shape android:shape="oval">
        <solid android:color="@color/white"/>
    </shape>
</item>
<item
    android:drawable="@drawable/messages" //here messages is my image name, please give here your image name.
    android:bottom="15dp"
    android:left="15dp"
    android:right="15dp"
    android:top="15dp"/>

Second make a view .xml file in layout folder and call the above .xml file with this way

<ImageView
   android:id="@+id/imageView2"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:src="@drawable/merchant_circle" />  // here merchant_circle will be your first .xml file name

It may help if you're less specific. Your expression there is "greedy", which may be interpreted different ways by different programs. Try this in vim:

%s/^<[^>]+>//

Strongly typed enums aiming to solve multiple problems and not only scoping problem as you mentioned in your question:

1. Provide type safety, thus eliminating implicit conversion to integer by integral promotion.
2. Specify underlying types.
3. Provide strong scoping.

Thus, it is impossible to implicitly convert a strongly typed enum to integers, or even its underlying type - that's the idea. So you have to use static_cast to make conversion explicit.

If your only problem is scoping and you really want to have implicit promotion to integers, then you better off using not strongly typed enum with the scope of the structure it is declared in.

Use an image editor to cut out a portion of the background, then apply CSS's background-repeat property to make the small image fill the area where it is used.

In some cases, background-repeat creates seams where the image repeats. A solution is to use an image editor as follows: starting with the background image, copy the image, flip (mirror, not rotate) the copy left-to-right, and paste it to the right edge of the original, overlapping 1 pixel. Crop to remove 1 pixel from the right edge of the combined image. Now repeat for the vertical: copy the combined image, flip the copy top-to-bottom, paste it to the bottom of the combined, overlapping one pixel. Crop to remove 1 pixel from the bottom. The resulting image should be seam-free.

The expression df1$id %in% idNums1 produces a logical vector. To negate it, you need to negate the whole vector:

!(df1$id %in% idNums1)

RandomStringUtils from Apache commons-lang might help:

RandomStringUtils.randomAlphanumeric(17).toUpperCase()

2017 update: RandomStringUtils has been deprecated, you should now use RandomStringGenerator.

EDIT Until such time as StackOverflow allows us to version our answers, this is an answer that works for Android 3 and below. Please don't downvote it because it's not working for you now, because it definitely works with older Android versions.

You should only need to add one line to your onCreateDialog() method:

@Override
protected Dialog onCreateDialog(int id) {
    //all other dialog stuff (which dialog to display)

    //this line is what you need:
    dialog.getWindow().setFlags(LayoutParams.FLAG_FULLSCREEN, LayoutParams.FLAG_FULLSCREEN);

    return dialog;
}

Not to compete with any of the great minds here, but a simple suggestion slightly different that the accepted answer above.

select dateadd(day, -(datepart(day,@date)+1,@date)

You can do this in very simple way using size property of angular modal.

var modal = $modal.open({
                    templateUrl: "/partials/welcome",
                    controller: "welcomeCtrl",
                    backdrop: "static",
                    scope: $scope,
                    size:'lg' // you can try different width like 'sm', 'md'
                });

Add step="0.01" to the <input type="number" /> parameters:

<input type="number" min="0.01" step="0.01" max="2500" value="25.67" />

Demo: http://jsfiddle.net/uzbjve2u/

But the Dollar sign must stay outside the textbox... every non-numeric or separator charachter will be cropped automatically.

Otherwise you could use a classic textbox, like described here.

The 'u' in front of the string values means the string is a Unicode string. Unicode is a way to represent more characters than normal ASCII can manage. The fact that you're seeing the u means you're on Python 2 - strings are Unicode by default on Python 3, but on Python 2, the u in front distinguishes Unicode strings. The rest of this answer will focus on Python 2.

You can create a Unicode string multiple ways:

>>> u'foo'
u'foo'
>>> unicode('foo') # Python 2 only
u'foo'

But the real reason is to represent something like this (translation here):

>>> val = u'???????????? ? ?????????????'
>>> val
u'\u041e\u0437\u043d\u0430\u043a\u043e\u043c\u044c\u0442\u0435\u0441\u044c \u0441 \u0434\u043e\u043a\u0443\u043c\u0435\u043d\u0442\u0430\u0446\u0438\u0435\u0439'
>>> print val
???????????? ? ?????????????

For the most part, Unicode and non-Unicode strings are interoperable on Python 2.

There are other symbols you will see, such as the "raw" symbol r for telling a string not to interpret backslashes. This is extremely useful for writing regular expressions.

>>> 'foo\"'
'foo"'
>>> r'foo\"'
'foo\\"'

Unicode and non-Unicode strings can be equal on Python 2:

>>> bird1 = unicode('unladen swallow')
>>> bird2 = 'unladen swallow'
>>> bird1 == bird2
True

but not on Python 3:

>>> x = u'asdf' # Python 3
>>> y = b'asdf' # b indicates bytestring
>>> x == y
False

I realise this is a little late but you could add the following to your code. This won't work for transparent pngs though, you'd need a cropping mask for that. Which I'm now going to see about.

outerLink {
    overflow: hidden;
    position: relative;
}

outerLink:hover:after {
    background: #000;
    content: "";
    display: block;
    height: 100%;
    left: 0;
    opacity: 0.5;
    position: absolute;
    top: 0;
    width: 100%;
}

You asked about performance. See this perf test comparing 'concat', '+' and 'join' - in short the + operator wins by far.

I needed to figure out the system host IP address for the emulator "Nox App Player". Here is how I figured out it was 172.17.100.2.

1. Installed Android Terminal Emulator from the app store
2. Issue ip link show command to show all network interfaces. Of particular interest was the eth1 interface
3. Issue ifconfig eth1 command, shows net as 172.17.100.15/255.255.255.0
4. Begin pinging addresses starting at 172.17.100.1, got a hit on `172.17.100.2'. Not sure if a firewall would interfere but it didn't in my case

Maybe this can help someone else figure it out for other emulators.

The 'pidof' command will not display pids of shell/perl/python scripts. So to find the process id’s of my Perl script I had to use the -x option i.e. 'pidof -x perlscriptname'

I did most of the suggested stuff here, still didnt work. Tried this and it worked: Open your XAMPP Control Panel, locate the Config button for the Apache module. Click on the Config button and Select PHP (php.ini). Open with any text editor and remove the semi-column before php_openssl. Save and Restart Apache. That should do!

?legend will tell you:

Arguments

x, y
the x and y co-ordinates to be used to position the legend. They can be specified by keyword or in any way which is accepted by xy.coords: See ‘Details’.

Details:

Arguments x, y, legend are interpreted in a non-standard way to allow the coordinates to be specified via one or two arguments. If legend is missing and y is not numeric, it is assumed that the second argument is intended to be legend and that the first argument specifies the coordinates.

The coordinates can be specified in any way which is accepted by xy.coords. If this gives the coordinates of one point, it is used as the top-left coordinate of the rectangle containing the legend. If it gives the coordinates of two points, these specify opposite corners of the rectangle (either pair of corners, in any order).

The location may also be specified by setting x to a single keyword from the list bottomright, bottom, bottomleft, left, topleft, top, topright, right and center. This places the legend on the inside of the plot frame at the given location. Partial argument matching is used. The optional inset argument specifies how far the legend is inset from the plot margins. If a single value is given, it is used for both margins; if two values are given, the first is used for x- distance, the second for y-distance.

I left a review asking for a fix. You can also do a bug report via the extension (after you install it) here. Instructions for doing so are here: https://support.google.com/chromecast/answer/3187017?hl=en

I hope Google gets on this. I need my console to show my errors, etc. Not theirs.

Yes, you can by using DBlink (postgresql only) and DBI-Link (allows foreign cross database queriers) and TDS_LInk which allows queries to be run against MS SQL server.

I have used DB-Link and TDS-link before with great success.

Try to use this command :

date | cut -d " " -f2-4 | tr " " "-" 

The output would be like: 21-Feb-2021

For a checked exception:

public class MyCustomException extends Exception { }

Technically, anything that extends Throwable can be an thrown, but exceptions are generally extensions of the Exception class so that they're checked exceptions (except RuntimeException or classes based on it, which are not checked), as opposed to the other common type of throwable, Errors which usually are not something designed to be gracefully handled beyond the JVM internals.

You can also make exceptions non-public, but then you can only use them in the package that defines them, as opposed to across packages.

As far as throwing/catching custom exceptions, it works just like the built-in ones - throw via

throw new MyCustomException()

and catch via

catch (MyCustomException e) { }

Just to point out that there is an approach using functions from the tidyverse, which I find more readable than gsub:

a %>% stringr::str_remove(pattern = ".*_")
