[Works On VIM 7.4 (2016) and 8.0 (2018)]

Certainly a corner case for this error, but I received it in a different situation, when attempting to overload the assignment operator=. It was a bit cryptic IMO (from g++ 8.1.1).

#include <cstdint>

enum DataType
{
  DT_INT32,
  DT_FLOAT
};

struct PrimitiveData
{
  union MyData
  {
    int32_t i;
    float f;
  } data;

  enum DataType dt;

  template<typename T>
  void operator=(T data)
  {
    switch(dt)
    {
      case DT_INT32:
      {
        data.i = data;
        break;
      }
      case DT_FLOAT:
      {
        data.f = data;
        break;
      }
      default:
      {
        break;
      }
    }
  }
};

int main()
{
  struct PrimitiveData pd;
  pd.dt = DT_FLOAT;
  pd = 3.4f;

  return 0;
}

I received 2 "identical" errors

error: request for member ‘i’ [and 'f'] in ‘data’, which is of non-class type ‘float’

(The equivalent error for clang is: error: member reference base type 'float' is not a structure or union)

for the lines data.i = data; and data.f = data;. Turns out the compiler was confusing local variable name 'data' and my member variable data. When I changed this to void operator=(T newData) and data.i = newData;, data.f = newData;, the error went away.

To summarize the excellent detailed explanations above, and in the simplest way I can think of, this is due to the limitations of the JVM built-in monitor, which 1) is acquired on the entire synchronization unit (block or object) and 2) does not discriminate about the specific condition being waited/notified on/about.

This means that if multiple threads are waiting on different conditions and notify() is used, the selected thread may not be the one which would make progress on the newly fulfilled condition - causing that thread (and other currently still waiting threads which would be able to fulfill the condition, etc..) not to be able to make progress, and eventually starvation or program hangup.

In contrast, notifyAll() enables all waiting threads to eventually re-acquire the lock and check for their respective condition, thereby eventually allowing progress to be made.

So notify() can be used safely only if any waiting thread is guaranteed to allow progress to be made should it be selected, which in general is satisfied when all threads within the same monitor check for only one and the same condition - a fairly rare case in real world applications.

In bash, I used this libreoffice command to convert all my xlsx files in the current directory:

for i   in *.xlsx; do  libreoffice --headless --convert-to csv "$i" ; done

It takes care of spaces in the filename.

Tried again some years later, and it didn't work. This thread gives some tips, but the quickiest solution was to run as root (or running a sudo libreoffice). Not elegant, but quick.

Use the command scalc.exe in Windows

I see my problem is a little bit different from yours, but I'll post this answer in case it helps someone else. I was using MB as shorthand instead of M when defining my memory_limit, and php was silently ignoring it. I changed it to an integer (in bytes) and the problem was solved.

My php.ini changed as follows: memory_limit = 512MB to memory_limit = 536870912. This fixed my problem. Hope it helps with someone else's! You can read up on php's shorthand here.

Good luck!

Edit

As Yaodong points out, you can just as easily use the correct shorthand, "M", instead of using byte values. I changed mine to byte values for debugging purposes and then didn't bother to change it back.

This should technically be achievable using window.location.reload():

HTML:

<button (click)="refresh()">Refresh</button>

TS:

refresh(): void {
    window.location.reload();
}

Update:

Here is a basic StackBlitz example showing the refresh in action. Notice the URL on "/hello" path is retained when window.location.reload() is executed.

java.io.NotSerializableException can occur when you serialize an inner class instance because:

serializing such an inner class instance will result in serialization of its associated outer class instance as well

Serialization of inner classes (i.e., nested classes that are not static member classes), including local and anonymous classes, is strongly discouraged

Ref: The Serializable Interface

The ugly system option

ptf <- function (txtToPrint,outFile){system(paste(paste(paste("echo '",cat(txtToPrint),sep = "",collapse = NULL),"'>",sep = "",collapse = NULL),outFile))}
#Prints txtToPrint to outFile in cwd. #!/bin/bash echo txtToPrint > outFile

If you (or a helpful admin) runs Set-ExecutionPolicy as administrator, the policy will be set for all users. (I would suggest "remoteSigned" rather than "unrestricted" as a safety measure.)

NB.: On a 64-bit OS you need to run Set-ExecutionPolicy for 32-bit and 64-bit PowerShell separately.

NOTE: This answer is for SQL Server 2005. For SQL Server 2008 and later, there are much better methods as seen in the other answers.

You can use INSERT with SELECT UNION ALL:

INSERT INTO MyTable  (FirstCol, SecondCol)
    SELECT  'First' ,1
    UNION ALL
SELECT  'Second' ,2
    UNION ALL
SELECT  'Third' ,3
...

Only for small datasets though, which should be fine for your 4 records.

Even though this an older question I stumbled here looking for a solution to a similar issue. After trying some of the solutions here I ended up going a different direction and thought I would add my solution for anyone else who ends up here.

In express 4.x you can get an instance of the router object and import another file that contains more routes. You can even do this recursively so your routes import other routes allowing you to create easy to maintain url paths. For example if I have a separate route file for my '/tests' endpoint already and want to add a new set of routes for '/tests/automated' I may want to break these '/automated' routes out into a another file to keep my '/test' file small and easy to manage. It also lets you logically group routes together by URL path which can be really convenient.

Contents of ./app.js:

var express = require('express'),
    app = express();

var testRoutes = require('./routes/tests');

// Import my test routes into the path '/test'
app.use('/tests', testRoutes);

Contents of ./routes/tests.js

var express = require('express'),
    router = express.Router();

var automatedRoutes = require('./testRoutes/automated');

router
  // Add a binding to handle '/tests'
  .get('/', function(){
    // render the /tests view
  })

  // Import my automated routes into the path '/tests/automated'
  // This works because we're already within the '/tests' route so we're simply appending more routes to the '/tests' endpoint
  .use('/automated', automatedRoutes);
 
module.exports = router;

Contents of ./routes/testRoutes/automated.js:

var express = require('express'),
    router = express.Router();

router
   // Add a binding for '/tests/automated/'
  .get('/', function(){
    // render the /tests/automated view
  })

module.exports = router;

UeberDB provides abstraction for various databases

Using jQuery it is very simple assuming the URL you wish to post to is on the same server or has implemented CORS

$(function() {
  $("#employeeLink").on("click",function(e) {
    e.preventDefault(); // cancel the link itself
    $.post(this.href,function(data) {
      $("#someContainer").html(data);
    });
  });
});

If you insist on using frames which I strongly discourage, have a form and submit it with the link

<form action="employee.action" method="post" target="myFrame" id="myForm"></form>

and use (in plain JS)

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the link
     document.getElementById("myForm").submit(); // but make sure nothing has name or ID="submit"
   });
 });

Without a form we need to make one

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the actual link
     var myForm = document.createElement("form");
     myForm.action=this.href;// the href of the link
     myForm.target="myFrame";
     myForm.method="POST";
     myForm.submit();
   });
 });

With OS > 3.0 you can do this:

//you need this import
#import <QuartzCore/QuartzCore.h>

[imageView.layer setBorderColor: [[UIColor blackColor] CGColor]];
[imageView.layer setBorderWidth: 2.0];

Where ever you use a <button> element by default it considers that button type="submit" so if you define the button type="button" then it won't consider that <button> as submit button.

with lombak 1.8.12, this worked for me

@Getter(value = lombok.AccessLevel.NONE)
@Setter(value = lombok.AccessLevel.NONE)

private int password;

you can make a shell script with those commands, and then chmod +x <scriptname.sh>, and then just run it by

./scriptname.sh

Its very simple to write a bash script

Mockup sh file:

#!/bin/sh
sudo command1
sudo command2 
.

.
sudo commandn

Yes you only need $() when you're using jQuery. If you want jQuery's help to do DOM things just keep this in mind.

$(this)[0] === this

Basically every time you get a set of elements back jQuery turns it into a jQuery object. If you know you only have one result, it's going to be in the first element.

$("#myDiv")[0] === document.getElementById("myDiv");

And so on...

if (-not ([string]::IsNullOrEmpty($version)))
{
    $request += "/" + $version
}

You can also use ! as an alternative to -not.

@ian this is not 100% accurate. If you have several iframes in a page you will have multiple onPageFinished (and onPageStarted). And if you have several redirects it may also fail. This approach solves (almost) all the problems:

boolean loadingFinished = true;
boolean redirect = false;

mWebView.setWebViewClient(new WebViewClient() {

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String urlNewString) {
        if (!loadingFinished) {
            redirect = true;
        }

        loadingFinished = false;
        webView.loadUrl(urlNewString);
        return true;
    }

    @Override
    public void onPageStarted(WebView view, String url) {
        loadingFinished = false;
        //SHOW LOADING IF IT ISNT ALREADY VISIBLE  
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        if (!redirect) {
           loadingFinished = true;
            //HIDE LOADING IT HAS FINISHED
        } else {
            redirect = false; 
        }
    }
});

UPDATE:

According to the documentation: onPageStarted will NOT be called when the contents of an embedded frame changes, i.e. clicking a link whose target is an iframe.

I found a specific case like that on Twitter where only a pageFinished was called and messed the logic a bit. To solve that I added a scheduled task to remove loading after X seconds. This is not needed in all the other cases.

UPDATE 2:

Now with current Android WebView implementation:

boolean loadingFinished = true;
boolean redirect = false;

    mWebView.setWebViewClient(new WebViewClient() {

        @Override
        public boolean shouldOverrideUrlLoading(
                WebView view, WebResourceRequest request) {
            if (!loadingFinished) {
               redirect = true;
            }

            loadingFinished = false;
            webView.loadUrl(request.getUrl().toString());
            return true;
        }

        @Override
        public void onPageStarted(
                WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
            loadingFinished = false;
            //SHOW LOADING IF IT ISNT ALREADY VISIBLE  
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            if (!redirect) {
               loadingFinished = true;
                //HIDE LOADING IT HAS FINISHED
            } else {
                redirect = false; 
            }
        }
    });

import requests

site_request = requests.get("https://abhiunix.in")

site_response = str(site_request.content)

print(site_response)

You can do it either way.

Because break can only be used inside a loop. It is used to break out of a loop (stop the loop).

<html>

    <body>

        <p>Enter some text in the fields below, and then press the "Submit form" button to submit the form.</p>

        <form id="myForm" action="/action_page.php">
          First name: <input type="text" name="fname"><br>
          Last name: <input type="text" name="lname"><br><br>
          <input type="button" onclick="myFunction()" value="Submit form">
        </form>

        <script>
            function myFunction() {
                document.getElementById("myForm").submit();
            }
        </script>

    </body>
</html>

In Ubuntu the file path is ./opt/lampp/var/mysql

Maybe a good starting point:

isChecked  = driver.findElement((By.id("idOftheElement"))).getAttribute("name");
if(!isChecked.contains("chkOptions$1"))
{
    driver.FindElement(By.Id("idOfTheElement")).Click();
}

I just wrote a quick function to do this. I needed it to handle many forms so I made it so it will accept a string separated by ','.

//function to make sure that all of the required fields of a post are sent. Returns True for error and False for NO error  
//accepts a string that is then parsed by "," into an array. The array is then checked for empty values.
function errorPOSTEmpty($stringOfFields) {
        $error = false;
            if(!empty($stringOfFields)) {
                // Required field names
                $required = explode(',',$stringOfFields);
                // Loop over field names
                foreach($required as $field) {
                  // Make sure each one exists and is not empty
                  if (empty($_POST[$field])) {
                    $error = true;
                    // No need to continue loop if 1 is found.
                    break;
                  }
                }
            }
    return $error;
}

So you can enter this function in your code, and handle errors on a per page basis.

$postError = errorPOSTEmpty('login,password,confirm,name,phone,email');

if ($postError === true) {
  ...error code...
} else {
  ...vars set goto POSTing code...
}

Limit is very simple, example limit first 50 rows

val df_subset = data.limit(50)

well... with 5.3 on the horizon, all will be better, because with 5.3, we'll get closures and with them anonymous functions

You can also override onContentChanged() which is among others fired when setContentView() has been called.

Download Microsoft Drivers for PHP for SQL Server. Extract the files and use one of:

File                             Thread Safe         VC Bulid
php_sqlsrv_53_nts_vc6.dll           No                  VC6
php_sqlsrv_53_nts_vc9.dll           No                  VC9
php_sqlsrv_53_ts_vc6.dll            Yes                 VC6
php_sqlsrv_53_ts_vc9.dll            Yes                 VC9

You can see the Thread Safety status in phpinfo().

Add the correct file to your ext directory and the following line to your php.ini:

extension=php_sqlsrv_53_*_vc*.dll

Use the filename of the file you used.

As Gordon already posted this is the new Extension from Microsoft and uses the sqlsrv_* API instead of mssql_*

Update:
On Linux you do not have the requisite drivers and neither the SQLSERV Extension.
Look at Connect to MS SQL Server from PHP on Linux? for a discussion on this.

In short you need to install FreeTDS and YES you need to use mssql_* functions on linux. see update 2

To simplify things in the long run I would recommend creating a wrapper class with requisite functions which use the appropriate API (sqlsrv_* or mssql_*) based on which extension is loaded.

Update 2: You do not need to use mssql_* functions on linux. You can connect to an ms sql server using PDO + ODBC + FreeTDS. On windows, the best performing method to connect is via PDO + ODBC + SQL Native Client since the PDO + SQLSRV driver can be incredibly slow.

Exact same thing, just omit the -c option. Apache's docs on it here.

htpasswd /etc/apache2/.htpasswd newuser

Also, htpasswd typically isn't run as root. It's typically owned by either the web server, or the owner of the files being served. If you're using root to edit it instead of logging in as one of those users, that's acceptable (I suppose), but you'll want to be careful to make sure you don't accidentally create a file as root (and thus have root own it and no one else be able to edit it).

Launch4j works on both Windows and Linux/Mac. But if you're running Linux/Mac, there is a way to embed your jar into a shell script that performs the autolaunch for you, so you have only one runnable file:

exestub.sh:

#!/bin/sh
MYSELF=`which "$0" 2>/dev/null`
[ $? -gt  0 -a -f "$0" ] && MYSELF="./$0"
JAVA_OPT=""
PROG_OPT=""
# Parse options to determine which ones are for Java and which ones are for the Program
while [ $# -gt 0 ] ; do
    case $1 in
        -Xm*) JAVA_OPT="$JAVA_OPT $1" ;;
        -D*)  JAVA_OPT="$JAVA_OPT $1" ;;
        *)    PROG_OPT="$PROG_OPT $1" ;;
    esac
    shift
done
exec java $JAVA_OPT -jar $MYSELF $PROG_OPT

Then you create your runnable file from your jar:

$ cat exestub.sh myrunnablejar.jar > myrunnable
$ chmod +x myrunnable

It works the same way launch4j works: because a jar has a zip format, which header is located at the end of the file. You can have any header you want (either binary executable or, like here, shell script) and run java -jar <myexe>, as <myexe> is a valid zip/jar file.

You can also use a function within stat_summary to calculate the mean and the hjust argument to place the text, you need a additional function but no additional data frame:

fun_mean <- function(x){
  return(data.frame(y=mean(x),label=mean(x,na.rm=T)))}


ggplot(PlantGrowth,aes(x=group,y=weight)) +
geom_boxplot(aes(fill=group)) +
stat_summary(fun.y = mean, geom="point",colour="darkred", size=3) +
stat_summary(fun.data = fun_mean, geom="text", vjust=-0.7)

A useful extension is to collect the results in a Dictionary for fast lookup (e.g. in a loop):

var resultDict = _dbContext.Projects
    .Where(p => p.Status == ProjectStatus.Active)
    .GroupBy(f => f.Country)
    .Select(g => new { country = g.Key, count = g.Count() })
    .ToDictionary(k => k.country, i => i.count);

In case you need short unique IDs as your filename, try shortuuid, shortuuid uses lowercase and uppercase letters and digits, and removing similar-looking characters such as l, 1, I, O and 0.

>>> import shortuuid
>>> shortuuid.uuid()
'Tw8VgM47kSS5iX2m8NExNa'
>>> len(ui)
22

compared to

>>> import uuid
>>> unique_filename = str(uuid.uuid4())
>>> len(unique_filename)
36
>>> unique_filename

A web service, as used by software developers, generally refers to an operation that is performed on a remote server and invoked using the XML/SOAP specification. As with all definitions, there are nuances to it, but that's the most common use of the term.

Another answer would be the NodeJS!

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Using terminal you will be able to start it using node command.

$ node
> 2 + 4
6
> 

Note: If you want to exit just type

.exit

You can also run a JavaScript file like this:

node file.js

You are trying to load a XIB named DetailViewController, but no such XIB exists or it's not member of your current target.

I had this error come up today due to a defect in code that was posting back a tremendous amount of times causing IIS to be flooded with requests. This essentially locked up IIS and so when I tried to debug, it 'timed out' trying to start the debugger. I simply restarted IIS, which took a few minutes, and it solved the issue.

I sure do wish this error was less generic, seems like there are several different ways to produce it.

In JavaScript, the type of key/value store you are attempting to use is an object literal, rather than an array. You are mistakenly creating a composite array object, which happens to have other properties based on the key names you provided, but the array portion contains no elements.

Instead, declare valueToPush as an object and push that onto cookie_value_add:

// Create valueToPush as an object {} rather than an array []
var valueToPush = {};

// Add the properties to your object
// Note, you could also use the valueToPush["productID"] syntax you had
// above, but this is a more object-like syntax
valueToPush.productID = productID;
valueToPush.itemColorTitle = itemColorTitle;
valueToPush.itemColorPath = itemColorPath;

cookie_value_add.push(valueToPush);

// View the structure of cookie_value_add
console.dir(cookie_value_add);

I tried everything and what worked best for my solution was to always have the vertical scrollbar show, and then add some negative margin to hide it.

This worked for IE11, FF60.9 and Chrome 80

body {
  -ms-overflow-style: none; /** IE11 */
  overflow-y: scroll;
  overflow-x: hidden;
  margin-right: -20px;
}

import java.util.*You can gethour and minute using calendar and formatter class. Calendar cal = Calendar.getInstance() and Formatter fmt=new Formatter() and set a format for display hour and minute fmt.format("%tl:%M",cal,cal)and print System.out.println(fmt) output shows like 10:12

If you're happy you know what you're doing and can accept the portability problems, on GCC for example you can disable the warning on the command line:

-Wno-multichar

I use this for my own apps to work with AVI and MP4 file headers for similar reasons to you.

In Eclipse:

• Right click on your build.xml

• click "Run As", click on "External Tool Configurations..."

• Select tab JRE. Select the JRE you are using.

Re-run the task, it should be fine now.

For Temporal Tables it is a bit more complicated due to the fact there may be some foreign keys and also exception:

Drop table operation failed on table XXX because it is not a supported operation on system-versioned temporal tables

What you can use is:

-- Disable constraints (foreign keys)
EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
GO

-- Disable system versioning (temporial tables)
EXEC sp_MSForEachTable '
 IF OBJECTPROPERTY(object_id(''?''), ''TableTemporalType'') = 2
  ALTER TABLE ? SET (SYSTEM_VERSIONING = OFF)
'
GO

-- Removing tables
EXEC sp_MSForEachTable 'DROP TABLE ?'
GO

Update PHP 7.4

Curly brace access syntax is deprecated since PHP 7.4

Update 2019

Moving on to the best practices of OOPS, @MrTrick's answer must be marked as correct, although my answer provides a hacked solution its not the best method.

Simply iterate its using {}

Example:

$videos{0}->id

This way your object is not destroyed and you can easily iterate through object.

For PHP 5.6 and below use this

$videos{0}['id']

Both array() and the stdClass objects can be accessed using the current() key() next() prev() reset() end() functions.

So, if your object looks like

object(stdClass)#19 (3) {
  [0]=>
  object(stdClass)#20 (22) {
    ["id"]=>
    string(1) "123"
  etc...

Then you can just do;

$id = reset($obj)->id; //Gets the 'id' attr of the first entry in the object

If you need the key for some reason, you can do;

reset($obj); //Ensure that we're at the first element
$key = key($obj);

Hope that works for you. :-) No errors, even in super-strict mode, on PHP 5.4

2022 Update:
After PHP 7.4, using current(), end(), etc functions on objects is deprecated.

In newer versions of PHP, use the ArrayIterator class:

$objIterator = new ArrayIterator($obj);

$id = $objIterator->current()->id; // Gets the 'id' attr of the first entry in the object

$key = $objIterator->key(); // and gets the key

Random number between 0 and 9 inclusive.

echo $((RANDOM%10))

    df.dropna(inplace=True)
    indices_to_keep = ~df.isin([np.nan, np.inf, -np.inf]).any(1)

I wrapped Jsch with some utility methods to make it a bit friendlier and called it

Jscp

Available here: https://github.com/willwarren/jscp

SCP utility to tar a folder, zip it, and scp it somewhere, then unzip it.

Usage:

// create secure context
SecureContext context = new SecureContext("userName", "localhost");

// set optional security configurations.
context.setTrustAllHosts(true);
context.setPrivateKeyFile(new File("private/key"));

// Console requires JDK 1.7
// System.out.println("enter password:");
// context.setPassword(System.console().readPassword());

Jscp.exec(context, 
           "src/dir",
           "destination/path",
           // regex ignore list 
           Arrays.asList("logs/log[0-9]*.txt",
           "backups") 
           );

Also includes useful classes - Scp and Exec, and a TarAndGzip, which work in pretty much the same way.

Your question says "Internet Explorer," but for those interested in other browsers, you can now use all: unset on buttons to unstyle them.

It doesn't work in IE, but it's well-supported everywhere else.

https://caniuse.com/#feat=css-all

Old Safari color warning: Setting the text color of the button after using all: unset can fail in Safari 13.1, due to a bug in WebKit. (The bug is fixed in Safari 14 and up.) "all: unset is setting -webkit-text-fill-color to black, and that overrides color." If you need to set text color after using all: unset, be sure to set both the color and the -webkit-text-fill-color to the same color.

Accessibility warning: For the sake of users who aren't using a mouse pointer, be sure to re-add some :focus styling, e.g. button:focus { outline: orange auto 5px } for keyboard accessibility.

And don't forget cursor: pointer. all: unset removes all styling, including the cursor: pointer, which makes your mouse cursor look like a pointing hand when you hover over the button. You almost certainly want to bring that back.

button {
  all: unset;
  color: blue;
  -webkit-text-fill-color: blue;
  cursor: pointer;
}

button:focus {
  outline: orange 5px auto;
}

<button>check it out</button>

How can I declare a class type, so that I ensure the object is a constructor of a general class?

A Constructor type could be defined as:

 type AConstructorTypeOf<T> = new (...args:any[]) => T;

 class A { ... }

 function factory(Ctor: AConstructorTypeOf<A>){
   return new Ctor();
 }

const aInstance = factory(A);

From my limited experience, this happens for two main reasons:

1. The lookup_value (arg1) is not present in the table_array (arg2)

The simple solution here is to use an error handler ending with Resume Next

2. The formats of arg1 and arg2 are not interpreted correctly

If your lookup_value is a variable you can enclose it with TRIM()

cellNum = wsFunc.VLookup(TRIM(currName), rngLook, 13, False)

Now For AppCompatEditText

Note: We need to use app:backgroundTint instead of android:backgroundTint

<android.support.v7.widget.AppCompatEditText
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:hint="Underline color change"
    app:backgroundTint="@color/blue_gray_light" />

(optional) Install git for windows (https://git-scm.com/) to get git bash. Git bash is much more similar to Linux terminal than Windows cmd.

Install Anaconda 3

https://www.anaconda.com/download/

It should set itself into Windows PATH. Restart your PC. Then pip should work in your cmd

Then in cmd (or git bash), run command

pip install openpyxl

There was a Python enhancement proposal PEP 299 which aimed to replace if __name__ == '__main__': idiom with def __main__:, but it was rejected. It's still a good read to know what to keep in mind when using if __name__ = '__main__':.

The standard Python library module random has what you want:

normalvariate(mu, sigma)
Normal distribution. mu is the mean, and sigma is the standard deviation.

For the algorithm itself, take a look at the function in random.py in the Python library.

The manual entry is here

Because int is a ValueType then you can use the following code:

if(Age == default(int) || Age == null)

or

if(Age.HasValue && Age != 0) or if (!Age.HasValue || Age == 0)

If you can live with pixel-sized margins, just add font-size: 1px; to the .frame. But remember, that now on the .frame 1em = 1px, which means, you need to set the margin in pixels too.

I don't recommend storing passwords in a script, but this is a way to what you indicate:

use 5.010;
my %user_table = ( tom => '123!', frank => '321!' );

say ( $user_table{ $name } eq $password ? 'You have gained access.'
    :                                     'Access denied!'
    );

Any time you want to enforce an association like this, it's a good idea to think of a table, and the most common form of table in Perl is the hash.

UPDATE mytbl
SET a = ABS(a)
where a < 0

I think that @Siva is on the right track (using DAYS()), but the nested CONCAT()s are making me dizzy. Here's my take.
Oh, there's no point in referencing sysdummy1, as you need to pull from a table regardless.
Also, don't use the implicit join syntax - it's considered an SQL Anti-pattern.

I'be wrapped the date conversion in a CTE for readability here, but there's nothing preventing you from doing it inline.

WITH Converted (convertedDate) as (SELECT DATE(SUBSTR(chdlm, 1, 4) || '-' ||
                                               SUBSTR(chdlm, 5, 2) || '-' ||    
                                               SUBSTR(chdlm, 7, 2))
                                   FROM Chcart00
                                   WHERE chstat = '05')

SELECT DAYS(CURRENT_DATE) - DAYS(convertedDate)
FROM Converted

You cannot remove an IDENTITY specification once set.

To remove the entire column:

ALTER TABLE yourTable
DROP COLUMN yourCOlumn;

Information about ALTER TABLE here

If you need to keep the data, but remove the IDENTITY column, you will need to:

• Create a new column
• Transfer the data from the existing IDENTITY column to the new column
• Drop the existing IDENTITY column.
• Rename the new column to the original column name

If u want to set background of the list then place the image before the < Textview>

< ImageView
android:background="@drawable/image_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>

and if u want to change color then put color code on above textbox like this

 android:textColor="#ffffff"

Confusing as it might be, the error also happens when a cpp file included in the project does not exist.

If you list your source files in CMakeLists.txt and mistakenly type a file name then you get this error.

I can see some people have asked, so on OSX you can still go to navigate->test or use cmd+shift+T

Remember you have to be focused in the class for this to work

this is not a regex solution.

alist={"I love ":""He loves"","Je t'aime ":"Il aime","Ich liebe ":"Er liebt"}

       print alist[k],statement.split(k)[1:]

If you put something like this in your .ssh/config:

Host githost
HostName git.host.de

then you should be able to use the basic syntax:

git push githost:/var/cache/git/project.git master

In Swift 3 use:

yourTextField.frame.size.height = 30

There are 2 options:

set serveroutput on format wrapped;

or

Open the 'view' menu and click on 'dbms output'. You should get a dbms output window at the bottom of the worksheet. You then need to add the connection (for some reason this is not done automatically).

The error is exactly what it says it is; you're trying to take sumall[0] when sumall is an int and that doesn't make any sense. What do you believe sumall should be?

Sometimes you have what appears to be a tuple with a leading underscore as in

def foo(bar):
    return _('my_' + bar)

In this case, what's going on is that _() is an alias for a localization function that operates on text to put it into the proper language, etc. based on the locale. For example, Sphinx does this, and you'll find among the imports

from sphinx.locale import l_, _

and in sphinx.locale, _() is assigned as an alias of some localization function.

SCENARIO 1 - wait for async task completion: I agree that WaitHandle/Auto|ManualResetEvent should be used in scenario where a thread is waiting for task on another thread to complete.

SCENARIO 2 - timing while loop: However, as a crude timing mechanism (while+Thread.Sleep) is perfectly fine for 99% of applications which does NOT require knowing exactly when the blocked Thread should "wake up*. The argument that it takes 200k cycles to create the thread is also invalid - the timing loop thread needs be created anyway and 200k cycles is just another big number (tell me how many cycles to open a file/socket/db calls?).

So if while+Thread.Sleep works, why complicate things? Only syntax lawyers would, be practical!

$('#userZipFiles option').prop('selected', function() {
        return this.defaultSelected;
    });     

See this question: Converting data.frame to xts order.by requires an appropriate time-based object, which suggests looking at argument to order.by,

Currently acceptable classes include: ‘Date’, ‘POSIXct’, ‘timeDate’, as well as ‘yearmon’ and ‘yearqtr’ where the index values remain unique.

And further suggests an explicit conversion using order.by = as.POSIXct,

df$Date <- as.POSIXct(strptime(df$Date,format),tz="UTC")
xts(df[, -1], order.by=as.POSIXct(df$Date))

Where your format is assigned elswhere,

format <- "%m/%d/%Y" #see strptime for details

Any binary-to-text encoding will do the trick. I use something like that

<data encoding="yEnc>
<![CDATA[ encoded binary data ]]>

Updated 10-second countdown using Hooks (a new feature proposal that lets you use state and other React features without writing a class. They’re currently in React v16.7.0-alpha).

import React, { useState, useEffect } from 'react';
import ReactDOM from 'react-dom';

const Clock = () => {
    const [currentCount, setCount] = useState(10);
    const timer = () => setCount(currentCount - 1);

    useEffect(
        () => {
            if (currentCount <= 0) {
                return;
            }
            const id = setInterval(timer, 1000);
            return () => clearInterval(id);
        },
        [currentCount]
    );

    return <div>{currentCount}</div>;
};

const App = () => <Clock />;

ReactDOM.render(<App />, document.getElementById('root'));

This should do the trick:

<% if (typeof(date) !== "undefined") { %>
    <span class="date"><%= date %></span>
<% } %>

Remember that in underscore.js templates if and for are just standard javascript syntax wrapped in <% %> tags.

Not an answer here and more like a comment, sorry but I can't comment.

In node V10, you can use the flag --experimental-modules to tell Nodejs you want to use import. But your entry script should end with .mjs.

Note this is still an experimental thing and should not be used in production.

// main.mjs
import utils from './utils.js'
utils.print();

// utils.js
module.exports={
    print:function(){console.log('print called')}
}

The best way is to check the type, because undefined/null/false are a tricky thing in JS. So:

if(typeof obj !== "undefined") {
    // obj is a valid variable, do something here.
}

Note that typeof always returns a string, and doesn't generate an error if the variable doesn't exist at all.

This post has a method to achieve this

from (zvrba) You can do it by redirecting the output to a file first. For example:

echo zz > bla.txt
set /p VV=<bla.txt
echo %VV%

You need to use parentheses: myList.insert([1, 2, 3]). When you leave out the parentheses, python thinks you are trying to access myList.insert at position 1, 2, 3, because that's what brackets are used for when they are right next to a variable.

WAMP uses different php.ini files in the CLI and for Apache. when you enable php_openssl through the WAMP UI, you enable it for Apache, not for the CLI. You need to modify C:\wamp\bin\php\php-5.4.3\php.ini to enable it for the CLI.

I had a similar problem, needed to trim trailing zeros from numbers like xx0000,x00000,xxx000

I used:

select LEFT(code,LEN(code)+1 - PATINDEX('%[1-Z]%',REVERSE(code))) from Tablename

Code is the name of the field with the number to be trimmed. Hope this helps someone else.

After replacing the character, you need to be asign to the variable.

var tt = "88,9827";
tt = tt.replace(/,/g, '.')
alert(tt)

In the alert box it will shows 88.9827

As of version 1.3 there's a service in module ng: $interval

function countController($scope, $interval){
    $scope.countDown = 10;    
    $interval(function(){console.log($scope.countDown--)},1000,0);
}??

Use with caution:

Note: Intervals created by this service must be explicitly destroyed when you are finished with them. In particular they are not automatically destroyed when a controller's scope or a directive's element are destroyed. You should take this into consideration and make sure to always cancel the interval at the appropriate moment. See the example below for more details on how and when to do this.

From: Angular's official documentation.

Ok, I just solved this issue on my own too. It is more important your JAVA_HOME, if you don't have a lower or no version compared to source/target properties from the Maven plugin, you will get this error.

Be sure to have a good version in your JAVA_HOME and have it included in your PATH.

Not in one line of code, there's nothing for dealing with dates in the C standard library. It would be fairly simple to write a function based on the Doomsday algorithm, or similar, though.

Just check the bootstrap. CSS and search for the class panel-heading and copy the default code.

Copy the default CSS to your personal CSS but vive it a diference classname like my-panel-header for example.

Edit the css Code from the new clones class created.

you can also pass the parameters through the command line. Command line arguments are stores in the array ARGV. so ARGV[0] is the first number and ARGV[1] the second number

#!/usr/bin/ruby

first_number = ARGV[0].to_i
second_number = ARGV[1].to_i

puts first_number + second_number

and you call it like this

% ./plus.rb 5 6
==> 11

FileInputStream will load a the file path you pass to the constructor as relative from the working directory of the Java process. Usually in a web container, this is something like the bin folder.

getResourceAsStream() will load a file path relative from your application's classpath.

To call a function inside a same controller in any laravel version follow as bellow

$role = $this->sendRequest('parameter');
// sendRequest is a public function

This is one of the best way to do so:

<script>
$(window).on('beforeunload', function() {
  $('body').hide();
  $(window).scrollTop(0);
});
</script>

This did the trick for me:Just remove all the libraries and then compile and run. It would prompt their are errors in your project confirm. Rerun the project after applying the libraries.

Simple class to support icon attribted placeholders in UITextView PlaceholderTextView

@IBOutlet weak var tvMessage: PlaceholderTextView!
//  TODO: - Create Icon Text Attachment
let icon: NSTextAttachment = NSTextAttachment()
icon.image = UIImage(named: "paper-plane")
let iconString = NSMutableAttributedString(attributedString: NSAttributedString(attachment: icon))

tvMessage.icon = icon

//  TODO: - Attributes
let textColor = UIColor.gray
let lightFont = UIFont(name: "Helvetica-Light", size: tvMessage.font!.pointSize)
let italicFont = UIFont(name: "Helvetica-LightOblique", size: tvMessage.font!.pointSize)

//  TODO: - Placeholder Attributed String
let message = NSAttributedString(string: " " + "Personal Message", attributes: [ NSFontAttributeName: lightFont!,   NSForegroundColorAttributeName: textColor])
iconString.append(message)
// TODO: - Italic Placeholder Part
let option = NSAttributedString(string: " " + "Optional", attributes: [ NSFontAttributeName: italicFont!, NSForegroundColorAttributeName: textColor])
iconString.append(option)

tvMessage.attributedPlaceHolder = iconString

tvMessage.layoutSubviews()

You must use

list.remove(indexYouWantToReplace);

first.

Your elements will become like this. [zero, one, three]

then add this

list.add(indexYouWantedToReplace, newElement)

Your elements will become like this. [zero, one, new, three]

You can use in your template.j2 {{ ansible_eth0.ipv4.address }} the same way you use {{inventory_hostname}}.

If you have more than this in javascript consider some javascript library, e.g. jquery which takes away a little speed, but gives you more readable code.

Your question's code via jquery:

$("td").hide();

Of course there are other javascript libraries out there, as this comparison on wikipedia shows.

I think a quick way to change the options of a widget is using the configure method.

In your case, it would look like this:

self.x.configure(state=NORMAL)

In Visual Studio 2012 you have to use (I think in Visual Studio 2010, too)

if $(Configuration) == Debug xcopy

$(ConfigurationName) was listed as a macro, but it wasn't assigned.

I'm pretty sure that the join doesn't even do what you want. If there are 100 records in table a with a null qid and 100 records in table b with a null qid, then the join as written should make a cross join and give 10,000 results for those records. If you look at the following code and run the examples, I think that the last one is probably more the result set you intended:

create table #test1 (id int identity, qid int)
create table #test2 (id int identity, qid int)

Insert #test1 (qid)
select null
union all
select null
union all
select 1
union all
select 2
union all
select null

Insert #test2 (qid)
select null
union all
select null
union all
select 1
union all
select 3
union all
select null


select * from #test2 t2
join #test1 t1 on t2.qid = t1.qid

select * from #test2 t2
join #test1 t1 on isnull(t2.qid, 0) = isnull(t1.qid, 0)


select * from #test2 t2
join #test1 t1 on 
 t1.qid = t2.qid OR ( t1.qid IS NULL AND t2.qid IS NULL )


select t2.id, t2.qid, t1.id, t1.qid from #test2 t2
join #test1 t1 on t2.qid = t1.qid
union all
select null, null,id, qid from #test1 where qid is null
union all
select id, qid, null, null from #test2  where qid is null

Yes you can do that.

Here is an example:

a{
    background:IMAGE-URL;
    display:block;
    height:IMAGE-HEIGHT;
    width:IMAGE-WIDTH;
}

Of course you can modify the above example to your need. The important thing is to make it appear as a block (display:block) or an inline block (display:inline-block).

Another option is Sheet1.Rows(x & ":" & Sheet1.Rows.Count).ClearContents (or .Clear). The reason you might want to use this method instead of .Delete is because any cells with dependencies in the deleted range (e.g. formulas that refer to those cells, even if empty) will end up showing #REF. This method will preserve formula references to the cleared cells.

Write the code:

  @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);

        Thread welcomeThread = new Thread() {

            @Override
            public void run() {
                try {
                    super.run();
                    sleep(10000)  //Delay of 10 seconds
                } catch (Exception e) {

                } finally {

                    Intent i = new Intent(SplashActivity.this,
                            MainActivity.class);
                    startActivity(i);
                    finish();
                }
            }
        };
        welcomeThread.start();
    }

If you are using C function fgetc then you should check a next character whether it is equal to the new line character or to EOF. For example

unsigned int count = 0;
while ( 1 )
{
   int c = fgetc( FileStream );

   if ( c == EOF || c == '\n' )
   {
      printF( "The length of the line is %u\n", count );
      count = 0;
      if ( c == EOF ) break;
   }
   else
   {
      ++count;
   }
}    

or maybe it would be better to rewrite the code using do-while loop. For example

unsigned int count = 0;
do
{
   int c = fgetc( FileStream );

   if ( c == EOF || c == '\n' )
   {
      printF( "The length of the line is %u\n", count );
      count = 0;
   }
   else
   {
      ++count;
   }
} while ( c != EOF );

Of course you need to insert your own processing of read xgaracters. It is only an example how you could use function fgetc to read lines of a file.

But if the program is written in C++ then it would be much better if you would use std::ifstream and std::string classes and function std::getline to read a whole line.

Is there any way to access to the $VAR by just executing export.bash without sourcing it ?

Quick answer: No.

But there are several possible workarounds.

The most obvious one, which you've already mentioned, is to use source or . to execute the script in the context of the calling shell:

$ cat set-vars1.sh 
export FOO=BAR
$ . set-vars1.sh 
$ echo $FOO
BAR

Another way is to have the script, rather than setting an environment variable, print commands that will set the environment variable:

$ cat set-vars2.sh
#!/bin/bash
echo export FOO=BAR
$ eval "$(./set-vars2.sh)"
$ echo "$FOO"
BAR

A third approach is to have a script that sets your environment variable(s) internally and then invokes a specified command with that environment:

$ cat set-vars3.sh
#!/bin/bash
export FOO=BAR
exec "$@"
$ ./set-vars3.sh printenv | grep FOO
FOO=BAR

This last approach can be quite useful, though it's inconvenient for interactive use since it doesn't give you the settings in your current shell (with all the other settings and history you've built up).

Your program will continue with the second if statement in the case of y == x, causing a ZeroDivisionError. You need to make the statements mutually exclusive; the way to do that is to use elif ("else if") instead of if:

import math
x = int(input("Enter a value for x: "))
y = int(input("Enter a value for y: "))
if y == x:
    print(1)
elif y == 1:         # see georg's comment
    print(x)
elif y > x:          # will be executed only if y != 1 and y != x
    print(0)
else:                # will be executed only if y != 1 and y != x and x <= y
    a = math.factorial(x)
    b = math.factorial(y)
    c = math.factorial(x-y)  # that appears to be useful to get the correct result
    div = a // (b * c)
    print(div)  

array_shift the only parameter is an array passed by reference. The return value of explode(".", $value) does not have any reference. Hence the error.

You should store the return value to a variable first.

    $arr = explode(".", $value);
    $extension = strtolower(array_pop($arr));   
    $fileName = array_shift($arr);

From PHP.net

The following things can be passed by reference:

- Variables, i.e. foo($a)
- New statements, i.e. foo(new foobar())
- [References returned from functions][2]

No other expressions should be passed by reference, as the result is undefined. For example, the following examples of passing by reference are invalid:

MongoDB needs data directory to store data. Default path is /data/db

When you start MongoDB engine, it searches this directory which is missing in your case. Solution is create this directory and assign rwx permission to user.

If you want to change the path of your data directory then you should specify it while starting mongod server like,

mongod --dbpath /data/<path> --port <port no> 

This should help you start your mongod server with custom path and port.

In terms of networking and security, the Backend is by far the most (should be) secure node.

The middle-end portion, usually being a web server, will be somewhat in the wild and cut off in many respects from a company's network. The middle-end node is usually placed in the DMZ and segmented from the network with firewall settings. Most of the server-side code parsing of web pages is handled on the middle-end web server.

Getting to the backend means going through the middle-end, which has a carefully crafted set of rules allowing/disallowing access to the vital nummies which are stored on the database (backend) server.

You will have to open the file in one way or another if you want to access the data within it. Obviously, one way is to open it in your Excel application instance, e.g.:-

(untested code)

Dim wbk As Workbook
Set wbk = Workbooks.Open("C:\myworkbook.xls")

' now you can manipulate the data in the workbook anyway you want, e.g. '

Dim x As Variant
x = wbk.Worksheets("Sheet1").Range("A6").Value

Call wbk.Worksheets("Sheet2").Range("A1:G100").Copy
Call ThisWorbook.Worksheets("Target").Range("A1").PasteSpecial(xlPasteValues)
Application.CutCopyMode = False

' etc '

Call wbk.Close(False)

Another way to do it would be to use the Excel ADODB provider to open a connection to the file and then use SQL to select data from the sheet you want, but since you are anyway working from within Excel I don't believe there is any reason to do this rather than just open the workbook. Note that there are optional parameters for the Workbooks.Open() method to open the workbook as read-only, etc.

I would make your final select as:

SELECT    EmplID
        , EmplName
        , InTime
        , [TimeOut]
        , [DateVisited]
        , CONVERT(varchar(3),DATEDIFF(minute,InTime, TimeOut)/60) + ':' +
          RIGHT('0' + CONVERT(varchar(2),DATEDIFF(minute,InTime,TimeOut)%60),2)
          as TotalHours
from times
Order By EmplID, DateVisited 

Any solution trying to use DATEDIFF(hour,... is bound to be complicated (if it's correct) because DATEDIFF counts transitions - DATEDIFF(hour,...09:59',...10:01') will return 1 because of the transition of the hour from 9 to 10. So I'm just using DATEDIFF on minutes.

The above can still be subtly wrong if seconds are involved (it can slightly overcount because its counting minute transitions) so if you need second or millisecond accuracy you need to adjust the DATEDIFF to use those units and then apply suitable division constants (as per the hours one above) to just return hours and minutes.

 Try this:- SELECT Case WHEN COLUMNNAME=0 THEN 'sex'
              ELSE WHEN COLUMNNAME=1 THEN 'Female' END AS YOURGRIDCOLUMNNAME FROM YOURTABLENAME

in your query for only true or false column

You do not need to use ORDER BY in inner query after WHERE clause because you have already used it in ROW_NUMBER() OVER (ORDER BY VRDATE DESC).

SELECT 
    * 
FROM (
    SELECT 
        Stockmain.VRNOA, 
        item.description as item_description, 
        party.name as party_name, 
        stockmain.vrdate, 
        stockdetail.qty, 
        stockdetail.rate, 
        stockdetail.amount, 
        ROW_NUMBER() OVER (ORDER BY VRDATE DESC) AS RowNum  --< ORDER BY
    FROM StockMain 
    INNER JOIN StockDetail 
        ON StockMain.stid = StockDetail.stid 
    INNER JOIN party 
        ON party.party_id = stockmain.party_id 
    INNER JOIN item 
        ON item.item_id = stockdetail.item_id 
    WHERE stockmain.etype='purchase' 
) AS MyDerivedTable
WHERE 
    MyDerivedTable.RowNum BETWEEN 1 and 5 

If anyone is also looking for how to get the name of the HTML tag, you can use "tagName": $(this)[0].tagName

You have a numpy array of strings, not floats. This is what is meant by dtype('<U9') -- a little endian encoded unicode string with up to 9 characters.

try:

return sum(np.asarray(listOfEmb, dtype=float)) / float(len(listOfEmb))

However, you don't need numpy here at all. You can really just do:

return sum(float(embedding) for embedding in listOfEmb) / len(listOfEmb)

Or if you're really set on using numpy.

return np.asarray(listOfEmb, dtype=float).mean()

if(success == true)
{
  //For wait 5 seconds
  setTimeout(function() 
  {
    location.reload();  //Refresh page
  }, 5000);
}

I don't know if there is a direct bash command to do this, but I usually do

normalDir="`cd "${dirToNormalize}";pwd`"
echo "${normalDir}"

and it works well.

For editing this is possible in nano via +n from command line, e.g.,

nano +16 file.txt

To open file.txt to line 16.

W3C doc says regarding "border-radius" property: "supported in IE9+, Firefox, Chrome, Safari, and Opera".

Hence I assume you're testing on IE8 or below.

For "regular elements" there is a solution compatible with IE8 & other old/poor browsers. See below.

HTML:

<div class="myWickedClass">
  <span class="myCoolItem">Some text</span> <span class="myCoolItem">Some text</span> <span class="myCoolItem"> Some text</span> <span class="myCoolItem">Some text</span>
</div>

CSS:

.myWickedClass{
  padding: 0 5px 0 0;
  background: #F7D358 url(../img/roundedCorner_right.png) top right no-repeat scroll;
  -moz-border-radius: 10px;
  -webkit-border-radius: 10px;
  border-radius: 10px;
  font: normal 11px Verdana, Helvetica, sans-serif;
  color: #A4A4A4;
}
.myWickedClass > .myCoolItem:first-child {
  padding-left: 6px;
  background: #F7D358 url(../img/roundedCorner_left.png) 0px 0px no-repeat scroll;
}
.myWickedClass > .myCoolItem {
  padding-right: 5px;
}

You need to create both roundedCorner_right.png & roundedCorner_left.png. These are work around for IE8 (& below) to fake the rounded corner feature.

So in this example above we apply the left rounded corner to the first span element in the containing div, & we apply the right rounded corner to the containing div. These images overlap the browser-provided "squary corners" & give the illusion of being part of a rounded element.

The idea for inputs would be to do the same logic. However, input is an empty element, " element is empty, it contains attributes only", in other word, you cannot wrap a span into an input such as <input><span class="myCoolItem"></span></input> to then use background images like in the previous example.

Hence the solution seems to be to do the opposite: wrap the input into another element. see this answer rounded corners of input elements in IE

One notice. On Windows, place your _curlrc in '%APPDATA%' or '%USERPROFILE%\Application Data'.

(\d+)\s+(\(.*?\))?\s?Z

Note the escaped parentheses, and the ? (zero or once) quantifiers. Any of the groups you don't want to capture can be (?: non-capture groups).

I agree about the spaces. \s is a better option there. I also changed the quantifier to insure there are digits at the beginning. As far as newlines, that would depend on context: if the file is parsed line by line it won't be a problem. Another option is to anchor the start and end of the line (add a ^ at the front and a $ at the end).

$(document).ready(function() {
  $.ajaxSetup({ cache: false }); // This part addresses an IE bug.  without it, IE will only load the first number and will never refresh
  setInterval(function() {
    $('#notice_div').load('response.php');
  }, 3000); // the "3000" 
});

If you want to use special character in javascript variable value, Escape Character (\) is required.

Backslash in your example is special character, too.

So you should do something like this,

var ttt = "aa ///\\\\\\"; // --> ///\\\

or

var ttt = "aa ///\\"; // --> ///\

But Escape Character not require for user input.

When you press / in prompt box or input field then submit, that means single /.

I meant in the template() call..

You just need to pass the results as an object. So instead of calling

var html = template(data);

do

var html = template({apidata: data});

and use {{#each apidata}} in your template code

demo at http://jsfiddle.net/KPCh4/4/
(removed some leftover if code that crashed)

Perhaps an example will help:

git rm --cached asd
git commit -m "the file asd is gone from the repository"

versus

git reset HEAD -- asd
git commit -m "the file asd remains in the repository"

Note that if you haven't changed anything else, the second commit won't actually do anything.

I personally use these following alias in bash

in ~/.gitconfig file

[alias]
    pushup = "!git push --set-upstream origin $(git symbolic-ref --short HEAD)"

and in ~/.bashrc or ~/.zshrc file

alias gpo="git pushup"
alias gpof="gpo -f"
alias gf="git fetch"
alias gp="git pull"

Word boundary \b is used where one word should be a word character and another one a non-word character. Regular Expression for negative number should be

--?\b\d+\b

Thou the above answer is widely accepted and well documented, I found some of the reason to post my answer here :-

    doNothing().when(InternalUtils.class); //This is the preferred way
                                           //to mock static void methods.
    InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());

Here, I dont understand why we are calling InternalUtils.sendEmail ourself. I will explain in my code why we don't need to do that.

mockStatic(Internalutils.class);

So, we have mocked the class which is fine. Now, lets have a look how we need to verify the sendEmail(/..../) method.

@PrepareForTest({InternalService.InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest {

    @Mock
    private InternalService.Order order;

    private InternalService internalService;

    @Before
    public void setup() {
        MockitoAnnotations.initMocks(this);
        internalService = new InternalService();
    }

    @Test
    public void processOrder() throws Exception {

        Mockito.when(order.isSuccessful()).thenReturn(true);
        PowerMockito.mockStatic(InternalService.InternalUtils.class);

        internalService.processOrder(order);

        PowerMockito.verifyStatic(times(1));
        InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());
    }

}

These two lines is where the magic is, First line tells the PowerMockito framework that it needs to verify the class it statically mocked. But which method it need to verify ?? Second line tells which method it needs to verify.

PowerMockito.verifyStatic(times(1));
InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());

This is code of my class, sendEmail api twice.

public class InternalService {

    public void processOrder(Order order) {
        if (order.isSuccessful()) {
            InternalUtils.sendEmail("", new String[1], "", "");
            InternalUtils.sendEmail("", new String[1], "", "");
        }
    }

    public static class InternalUtils{

        public static void sendEmail(String from, String[]  to, String msg, String body){

        }

    }

    public class Order{

        public boolean isSuccessful(){
            return true;
        }

    }

}

As it is calling twice you just need to change the verify(times(2))... that's all.

Here my example ssl socket server threads (multiple connection) https://github.com/breakermind/CppLinux/blob/master/QtSslServerThreads/breakermindsslserver.cpp

#include <pthread.h>
#include <stdio.h>
#include <stdlib.h>
#include <string>
#include <unistd.h>
#include <iostream>

#include <breakermindsslserver.h>

using namespace std;

int main(int argc, char *argv[])
{
    BreakermindSslServer boom;
    boom.Start(123,"/home/user/c++/qt/BreakermindServer/certificate.crt", "/home/user/c++/qt/BreakermindServer/private.key");
    return 0;
}

When retrying due to error, you should always:

• implement a retry limit, or you may get blocked on an infinite loop
• implement a delay, or you'll hammer resources too hard, such as your CPU or the already distressed remote server

A simple generic way to solve this problem while covering those concerns would be to use the backoff library. A basic example:

import backoff

@backoff.on_exception(
    backoff.expo,
    MyException,
    max_tries=5
)
def make_request(self, data):
    # do the request

This code wraps make_request with a decorator which implements the retry logic. We retry whenever our specific error MyException occurs, with a limit of 5 retries. Exponential backoff is a good idea in this context to help minimize the additional burden our retries place on the remote server.

I had the same problem so I invested the possible solution given but at the end I decided to implement my ';' separated list of String.

so I have

// a ; separated list of arguments
String arguments;

public List<String> getArguments() {
    return Arrays.asList(arguments.split(";"));
}

This way the list is easily readable/editable in the database table;

Try /me/taggable_friends?limit=5000 using your JavaScript code

Or

try the Graph API:

https://graph.facebook.com/v2.3/user_id_here/taggable_friends?access_token=

It might be an easiest way-

    String recipientList = mEditTextTo.getText().toString();
    String[] recipients = recipientList.split(",");

    String subject = mEditTextSubject.getText().toString();
    String message = mEditTextMessage.getText().toString();

    Intent intent = new Intent(Intent.ACTION_SEND);
    intent.putExtra(Intent.EXTRA_EMAIL, recipients);
    intent.putExtra(Intent.EXTRA_SUBJECT, subject);
    intent.putExtra(Intent.EXTRA_TEXT, message);

    intent.setType("message/rfc822");
    startActivity(Intent.createChooser(intent, "Choose an email client"));

"exec nohup setsid your_command"

the nohup allows your_command to continue even though the process that launched may terminate first. If it does, the the SIGNUP signal will be sent to your_command causing it to terminate (unless it catches that signal and ignores it).

Select *  from  emp where joindate between date1 and date2;

But this query not show proper data.

Eg

1-jan-2013 to 12-jan-2013.

But it's show data

1-jan-2013 to 11-jan-2013.

zoom: 145%;
-moz-transform: scale(1.45);

use this to be on the safer side

I'm running Eclipse Indigo 64 bit on Windows 7 64 bit and I kept getting missing dependency errors associated with Maven and other plugins using the JBoss Tools 3.3.X latest download. Here is the link.

So, I opted to only install Hibernate Tools with nothing else by typing in "hibernate" at the top of the install software dialog in eclipse. Only 4 items showed up, so that is all I installed. It worked fine with no problems. Here is the tutorial that I used to get it installed properly after several failed attempts.

I don't know if part of this was due to having a lot of plugins already installed or if this is the best solution or not, but I thought I'd share it with everyone.

_{Additional details to the previous answer:}

While React's setState is asynchronous (both classes and hooks), and it's tempting to use that fact to explain the observed behavior, it is not the reason why it happens.

TLDR: The reason is a closure scope around an immutable const value.

Solutions:

• read the value in render function (not inside nested functions):

    useEffect(() => { setMovies(result) }, [])
    console.log(movies)
  

• add the variable into dependencies (and use the react-hooks/exhaustive-deps eslint rule):

    useEffect(() => { setMovies(result) }, [])
    useEffect(() => { console.log(movies) }, [movies])
  

• use a mutable reference (when the above is not possible):

    const moviesRef = useRef(initialValue)
    useEffect(() => {
      moviesRef.current = result
      console.log(moviesRef.current)
    }, [])
  

Explanation why it happens:

If async was the only reason, it would be possible to await setState().

However, both props and state are assumed to be unchanging during 1 render.

Treat this.state as if it were immutable.

With hooks, this assumption is enhanced by using constant values with the const keyword:

const [state, setState] = useState('initial')

The value might be different between 2 renders, but remains a constant inside the render itself and inside any closures (functions that live longer even after render is finished, e.g. useEffect, event handlers, inside any Promise or setTimeout).

Consider following fake, but synchronous, React-like implementation:

// sync implementation:

let internalState
let renderAgain

const setState = (updateFn) => {
  internalState = updateFn(internalState)
  renderAgain()
}

const useState = (defaultState) => {
  if (!internalState) {
    internalState = defaultState
  }
  return [internalState, setState]
}

const render = (component, node) => {
  const {html, handleClick} = component()
  node.innerHTML = html
  renderAgain = () => render(component, node)
  return handleClick
}

// test:

const MyComponent = () => {
  const [x, setX] = useState(1)
  console.log('in render:', x) // ?
  
  const handleClick = () => {
    setX(current => current + 1)
    console.log('in handler/effect/Promise/setTimeout:', x) // ? NOT updated
  }
  
  return {
    html: `<button>${x}</button>`,
    handleClick
  }
}

const triggerClick = render(MyComponent, document.getElementById('root'))
triggerClick()
triggerClick()
triggerClick()

<div id="root"></div>

You should use :first-child instead of :first:

Sounds like you're wanting to iterate through them. You can do this using .each().

Example:

$('td:first-child').each(function() {
    console.log($(this).text());
});

Result:

nonono
nonono2
nonono3

Alernatively if you're not wanting to iterate:

$('td:first-child').css('background', '#000');

JSFiddle demo.

which(df==my.val, arr.ind=TRUE)

var inputs = document.getElementsByTagName('input');
for (var i = 0; i < inputs.length; ++i) {
  // ...
}

Send the data from the form:

$("#change_section_type").live "change", ->
url = $(this).attr("data-url")
postData = $(this).parents("#contract_setting_form").serializeArray()
$.ajax
  type: "PUT"
  url: url
  dataType: "script"
  data: postData

You can write DateTime? newdate = null;

To load an external file from spark-shell simply do

Just in case what happened to me is happening to somebody else, I need to say this:
I was in my .git directory within my project when I was getting this error.
I searched and scoured for answers, but nothing worked.
All I had to do was get back to the right directory ( cd .. ).
It was kind of a face-palm moment for me.
In case there's anyone else out there as silly as me, I hope you found this answer helpful.

Rather than going the harder route of downloading specific packages. I prefer to go the faster route of using Conda. pip has its issues.

I've had luck recovering the commit by looking at the reflog, which was located at .git/logs/HEAD

I then had to scoll down to the end of the file, and I found the commit I just lost.

Fix of this problem is add SVN directory(C:\Program Files\TortoiseSVN\bin) to Path system property

In order to navigate to a different drive/directory you can do it in convenient way (instead of typing cd /e/Study/Codes), just type in cd[Space], and drag-and-drop your directory Codes with your mouse to git bash, hit [Enter].

I think this should be fine.

static boolean addWillOverFlow(int a, int b) {
    return (Integer.signum(a) == Integer.signum(b)) && 
            (Integer.signum(a) != Integer.signum(a+b)); 
}

Basically, you need to include the Wordpress loop in your search.php template to loop through the search results and show them as part of the template.

Below is a very basic example from The WordPress Theme Search Template and Page Template over at ThemeShaper.

<?php
/**
 * The template for displaying Search Results pages.
 *
 * @package Shape
 * @since Shape 1.0
 */

get_header(); ?>

        <section id="primary" class="content-area">
            <div id="content" class="site-content" role="main">

            <?php if ( have_posts() ) : ?>

                <header class="page-header">
                    <h1 class="page-title"><?php printf( __( 'Search Results for: %s', 'shape' ), '<span>' . get_search_query() . '</span>' ); ?></h1>
                </header><!-- .page-header -->

                <?php shape_content_nav( 'nav-above' ); ?>

                <?php /* Start the Loop */ ?>
                <?php while ( have_posts() ) : the_post(); ?>

                    <?php get_template_part( 'content', 'search' ); ?>

                <?php endwhile; ?>

                <?php shape_content_nav( 'nav-below' ); ?>

            <?php else : ?>

                <?php get_template_part( 'no-results', 'search' ); ?>

            <?php endif; ?>

            </div><!-- #content .site-content -->
        </section><!-- #primary .content-area -->

<?php get_sidebar(); ?>
<?php get_footer(); ?>

Use these sizes 57x57, 72x72, 114x114, 144x144 then do this in the head of your document:

<link rel="apple-touch-icon" href="apple-touch-icon-iphone.png" />
<link rel="apple-touch-icon" sizes="72x72" href="apple-touch-icon-ipad.png" />
<link rel="apple-touch-icon" sizes="114x114" href="apple-touch-icon-iphone4.png" />

This will look good on all apple devices. ;)

You're using span6 and span2. Both of these classes are "float:left" meaning, if possible they will always try to sit next to each other. Twitter bootstrap is based on a 12 grid system. So you should generally always get the span**#** to add up to 12.

E.g.: span4 + span4 + span4 OR span6 + span6 OR span4 + span3 + span5.

To force a span down though, without listening to the previous float you can use twitter bootstraps clearfix class. To do this, your code should look like this:

<ul class="nav nav-tabs span2">
  <li><a href="./index.html"><i class="icon-black icon-music"></i></a></li>
  <li><a href="./about.html"><i class="icon-black icon-eye-open"></i></a></li>
  <li><a href="./team.html"><i class="icon-black icon-user"></i></a></li>
  <li><a href="./contact.html"><i class="icon-black icon-envelope"></i></a></li>
</ul>
<!-- Notice this following line -->
<div class="clearfix"></div>
<div class="well span6">
  <h3>I wish this appeared on the next line without having to gratuitously use BR!</h3>
</div>

This is similar to qntmfred's solution, but using a direct table dump. This option is slightly faster (see BCP docs):

to export:

bcp "[MyDatabase].dbo.Customer " out "Customer.bcp" -N -S localhost -T -E

to import:

bcp [MyDatabase].dbo.Customer in "Customer.bcp" -N -S localhost -T -E -b 10000

Now, it's very much simplified in Visual Studio 2015 and later. You can do downgrade / upgrade within the User interface itself, without executing commands in the Package Manager Console.

1. Right click on your project and *go to Manage NuGet Packages.

2. Look at the below image.

   • Select your Package and Choose the Version, which you wanted to install.

Very very simple, isn't it? :)

A simple way to make it work is to run your script from the parent directory using python's -m flag, e.g. python -m packagename.scriptname. Obviously in this situation you need an __init__.py file to turn your directory into a package.

Connect to a database and execute the command:

SHOW data_directory;

There are two options. The first (and better) one is using the Fetch as Google option in Webmaster Tools that Mike Flynn commented about. Here are detailed instructions:

1. Go to: https://www.google.com/webmasters/tools/ and log in
2. If you haven't already, add and verify the site with the "Add a Site" button
3. Click on the site name for the one you want to manage
4. Click Crawl -> Fetch as Google
5. Optional: if you want to do a specific page only, type in the URL
6. Click Fetch
7. Click Submit to Index
8. Select either "URL" or "URL and its direct links"
9. Click OK and you're done.

With the option above, as long as every page can be reached from some link on the initial page or a page that it links to, Google should recrawl the whole thing. If you want to explicitly tell it a list of pages to crawl on the domain, you can follow the directions to submit a sitemap.

Your second (and generally slower) option is, as seanbreeden pointed out, submitting here: http://www.google.com/addurl/

Update 2019:

1. Login to - Google Search Console
2. Add a site and verify it with the available methods.
3. After verification from the console, click on URL Inspection.
4. In the Search bar on top, enter your website URL or custom URLs for inspection and enter.
5. After Inspection, it'll show an option to Request Indexing
6. Click on it and GoogleBot will add your website in a Queue for crawling.

CDATA is necessary in any XML dialect, because text within an XML node is treated as a child element before being evaluated as JavaScript. This is also the reason why JSLint complains about the < character in regexes.

The following example using the iris dataset works fine:

dat = melt(subset(iris, select = c("Sepal.Length","Sepal.Width", "Species")),
      id.vars = "Species")
ggplot(aes(x = 1:nrow(iris), y = value, color = variable), data = dat) +  
      geom_point() + geom_line()

If it doesn't matter the order of the elements. you can swap between the elements foo[x] and foo[0], then call foo.drop(1).

foo.drop(n) removes (n) first elements from the array.

I guess this is the simplest and resource efficient way to do.

PS: indexOf can be implemented in many ways, this is my version.

Integer indexOf(String[] arr, String value){
    for(Integer i = 0 ; i < arr.length; i++ )
        if(arr[i] == value)
            return i;         // return the index of the element
    return -1                 // otherwise -1
}

while (true) {
   Integer i;
   i = indexOf(foo,"a")
   if (i == -1) break;
   foo[i] = foo[0];           // preserve foo[0]
   foo.drop(1);
}

from help (spec -h):

-l, --line LINE_NUMBER           Execute example group or example at given line.
                                 (does not work for dynamically generated examples)

Example: spec spec/runner_spec.rb -l 162

This command will show also if the file is hidden adb shell ls -laR | grep filename

Each image has a resource-number, which is an integer. Pass this number to "setImageResource" and you should be ok.

Check this link for further information:
http://developer.android.com/guide/topics/resources/accessing-resources.html

e.g.:

imageView.setImageResource(R.drawable.myimage);

You are trying to access the class as opposed to the object. That statement can be confusing to beginners, but you are effectively trying to open your house door by picking up the door on your house plans.

If you actually wanted to access the form components directly from a class (which you don't) you would use the variable that instantiates your form.

Depending on which way you want to go you'd be better of either sending the text of a control or whatever to a method in your classes eg

public void DoSomethingWithText(string formText)
{
   // do something text in here
}

or exposing properties on your form class and setting the form text in there - eg

string SomeProperty
{
   get 
   {
      return textBox1.Text;
   }
   set
   {
      textBox1.Text = value;
   }
}

You can like:

window.open('url', 'window name', 'window settings')

jQuery:

$('a#link_id').click(function(){
  window.open('url', 'window name', 'window settings');
  return false;
});

You could also set the target to _blank actually.

>>> df.groupby('id').first()
     value
id        
1    first
2    first
3    first
4   second
5    first
6    first
7   fourth

If you need id as column:

>>> df.groupby('id').first().reset_index()
   id   value
0   1   first
1   2   first
2   3   first
3   4  second
4   5   first
5   6   first
6   7  fourth

To get n first records, you can use head():

>>> df.groupby('id').head(2).reset_index(drop=True)
    id   value
0    1   first
1    1  second
2    2   first
3    2  second
4    3   first
5    3   third
6    4  second
7    4   fifth
8    5   first
9    6   first
10   6  second
11   7  fourth
12   7   fifth

What is the best place is your question. The best place is inside the Controller.Initialize method. MSDN writes that it is called after the constructor and before the action method. In contrary of overriding OnActionExecuting, placing your code in the Initialize method allow you to benefit of having all custom data annotation and attribute on your classes and on your properties to be localized.

For example, my localization logic come from an class that is injected to my custom controller. I have access to this object since Initialize is called after the constructor. I can do the Thread's culture assignation and not having every error message displayed correctly.

 public BaseController(IRunningContext runningContext){/*...*/}

 protected override void Initialize(RequestContext requestContext)
 {
     base.Initialize(requestContext);
     var culture = runningContext.GetCulture();
     Thread.CurrentThread.CurrentUICulture = culture;
     Thread.CurrentThread.CurrentCulture = culture;
 }

Even if your logic is not inside a class like the example I provided, you have access to the RequestContext which allow you to have the URL and HttpContext and the RouteData which you can do basically any parsing possible.

You can use:

<input (input)="saverange()>

Editing a Parameter The set method of the URLSearchParams object sets the new value of the parameter.

After setting the new value you can get the new query string with the toString() method. This query string can be set as the new value of the search property of the URL object.

The final new url can then be retrieved with the toString() method of the URL object.

var query_string = url.search;

var search_params = new URLSearchParams(query_string); 

// new value of "id" is set to "101"
search_params.set('id', '101');

// change the search property of the main url
url.search = search_params.toString();

// the new url string
var new_url = url.toString();

// output : http://demourl.com/path?id=101&topic=main
console.log(new_url);

Small update due to golang api change, please omit .UTC() :

time.Now().UTC().UnixNano() -> time.Now().UnixNano()

import (
    "fmt"
    "math/rand"
    "time"
)

func main() {
    rand.Seed(time.Now().UnixNano())
    fmt.Println(randomInt(100, 1000))
}

func randInt(min int, max int) int {
    return min + rand.Intn(max-min)
}

This is TypeScript version of @Joel's answer. It is usable after Node 11.0:

import { promises as fs } from 'fs';

async function loadMonoCounter() {
    const data = await fs.readFile('monolitic.txt', 'binary');
    return Buffer.from(data);
}

By default you use UNICODE so I suggest using faulty's method

int bar = int.Parse(foo.ToString());

Even though the numeric values under are the same for digits and basic Latin chars.

For WINDOWS users

"standard" packaging tools situation is improving recently:

• on pypi itself, there are now 48% of wheel packages as of sept. 11th 2015 (up from 38% in may 2015 , 24% in sept. 2014),

• the wheel format is now supported out-of-the-box per latest python 2.7.9,

"standard"+"tweaks" packaging tools situation is improving also:

• you can find nearly all scientific packages on wheel format at http://www.lfd.uci.edu/~gohlke/pythonlibs,

• the mingwpy project may bring one day a 'compilation' package to windows users, allowing to install everything from source when needed.

"Conda" packaging remains better for the market it serves, and highlights areas where the "standard" should improve.

(also, the dependency specification multiple-effort, in standard wheel system and in conda system, or buildout, is not very pythonic, it would be nice if all these packaging 'core' techniques could converge, via a sort of PEP)

    private void TurnOnAutocomplete()
    {
        textBox.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
        textBox.AutoCompleteSource = AutoCompleteSource.CustomSource;
        AutoCompleteStringCollection collection = new AutoCompleteStringCollection();
        string[] arrayOfWowrds = new string[];

        try
        {
            //Read in data Autocomplete list to a string[]
            string[] arrayOfWowrds = new string[];
        }
        catch (Exception err)
        {
            MessageBox.Show(err.Message, "File Missing", MessageBoxButtons.OK, MessageBoxIcon.Error);
        }

        collection.AddRange(arrayOFWords);
        textBox.AutoCompleteCustomSource = collection;
    }

You only need to call this once after you have your data needed for the autocomplete list. Once bound it stays with the textBox. You do not need to or want to call it every time the text is changed in the textBox, that will kill your program.

Starting with Java 11, you can use the repeat(...) method:

"0".repeat(Integer.numberOfLeadingZeros(i) - 16) + Integer.toBinaryString(i)

Or, if you need 32-bit representation of any integer:

"0".repeat(Integer.numberOfLeadingZeros(i != 0 ? i : 1)) + Integer.toBinaryString(i)

Login to your WHM panel if you have access to

Then go to Software -> MultiPHP INI Editor

Then select the php version from the dropdown, then scroll down for the upload_max_filesize which will be 2M by default, now increase it according to your need.

Also enable the file_uploads for HTTP file uploads for convenience.

If you don't have access to WHM, then follow the .htaccess method.

Description

There are many ways to validate your TextBox. You can do this on every keystroke, at a later time, or on the Validating event.

The Validating event gets fired if your TextBox looses focus. When the user clicks on a other Control, for example. If your set e.Cancel = true the TextBox doesn't lose the focus.

MSDN - Control.Validating Event When you change the focus by using the keyboard (TAB, SHIFT+TAB, and so on), by calling the Select or SelectNextControl methods, or by setting the ContainerControl.ActiveControl property to the current form, focus events occur in the following order

Enter

GotFocus

Leave

Validating

Validated

LostFocus

When you change the focus by using the mouse or by calling the Focus method, focus events occur in the following order:

Enter

GotFocus

LostFocus

Leave

Validating

Validated

Sample Validating Event

private void textBox1_Validating(object sender, CancelEventArgs e)
{
    if (textBox1.Text != "something")
        e.Cancel = true;
}

Update

You can use the ErrorProvider to visualize that your TextBox is not valid. Check out Using Error Provider Control in Windows Forms and C#

I also think chart.Boxplot is the best option, it gives you the position of the mean but if you have a matrix with returns all you need is one line of code to get all the boxplots in one graph.

Here is a small ETF portfolio example.

library(zoo)
library(PerformanceAnalytics)
library(tseries)
library(xts)

VTI.prices = get.hist.quote(instrument = "VTI", start= "2007-03-01", end="2013-03-01",
                        quote = c("AdjClose"),provider = "yahoo",origin ="1970-01-01", 
                        compression = "m", retclass = c("zoo"))

VEU.prices = get.hist.quote(instrument = "VEU", start= "2007-03-01", end="2013-03-01",
                        quote = c("AdjClose"),provider = "yahoo",origin ="1970-01-01", 
                        compression = "m", retclass = c("zoo"))

VWO.prices = get.hist.quote(instrument = "VWO", start= "2007-03-01", end="2013-03-01",
                        quote = c("AdjClose"),provider = "yahoo",origin ="1970-01-01", 
                        compression = "m", retclass = c("zoo"))

TLT.prices = get.hist.quote(instrument = "TLT", start= "2007-03-01", end="2013-03-01",
                        quote = c("AdjClose"),provider = "yahoo",origin ="1970-01-01", 
                        compression = "m", retclass = c("zoo"))

TIP.prices = get.hist.quote(instrument = "TIP", start= "2007-03-01", end="2013-03-01",
                         quote = c("AdjClose"),provider = "yahoo",origin ="1970-01-01", 
                         compression = "m", retclass = c("zoo"))

index(VTI.prices) = as.yearmon(index(VTI.prices))
index(VEU.prices) = as.yearmon(index(VEU.prices))
index(VWO.prices) = as.yearmon(index(VWO.prices))

index(VNQ.prices) = as.yearmon(index(VNQ.prices))
index(TLT.prices) = as.yearmon(index(TLT.prices))
index(TIP.prices) = as.yearmon(index(TIP.prices))

Prices.z=merge(VTI.prices, VEU.prices, VWO.prices, VNQ.prices, 
           TLT.prices, TIP.prices)

colnames(Prices.z) = c("VTI", "VEU", "VWO" , "VNQ", "TLT", "TIP")

returnscc.z = diff(log(Prices.z))

start(returnscc.z)
end(returnscc.z)
colnames(returnscc.z) 
head(returnscc.z)

Return Matrix

ret.mat = coredata(returnscc.z)
class(ret.mat)
colnames(ret.mat)
head(ret.mat)

Box Plot of Return Matrix

chart.Boxplot(returnscc.z, names=T, horizontal=TRUE, colorset="darkgreen", as.Tufte =F,
          mean.symbol = 20, median.symbol="|", main="Return Distributions Comparison",
          element.color = "darkgray", outlier.symbol = 20, 
          xlab="Continuously Compounded Returns", sort.ascending=F)

You can try changing the mean.symbol, and remove or change the median.symbol. Hope it helped. :)

To avoid some of the problems mentioned above (not robust for nulls etc etc), to get first and last element in a list an approach could be

import java.util.List;

public static final <A> A getLastElement(List<A> list) {
    return list != null ? getElement(list, list.size() - 1) : null;
}

public static final <A> A getFirstElement(List<A> list) {
    return list != null ? getElement(list, 0) : null;
}   

private static final <A> A getElement(List<A> list, int pointer) {
    A res = null;
    if (list.size() > 0) {
        res = list.get(pointer);            
    }
    return res;
}

The convention adopted is that the first/last element of an empty list is null...

In C#:

private string studentName;

At the end of line after semicolon(;) Just Press

Ctrl + R + E

It will show a popup window like this: On click of Apply or pressing of ENTER it will generate the following code of property:

public string StudentName
        {
            get
            {
                return studentName;
            }

            set
            {
                studentName = value;
            }
        }

In VB:

Private _studentName As String

At the end of line (after String) Press, Make sure you place _(underscore) at the start because it will add number at the end of property:

Ctrl + R + E

The same window will appear:

On click of Apply or pressing of ENTER it will generate the following code of property with number at the end like this:

Public Property StudentName As String
        Get
            Return _studentName
        End Get
        Set(value As String)
            _studentName = value
        End Set
    End Property

With number properties are like this:

Private studentName As String
 Public Property StudentName1 As String
        Get
            Return studentName
        End Get
        Set(value As String)
            studentName = value
        End Set
    End Property

The tibble package now has a dedicated function that converts row names to an explicit variable.

library(tibble)
rownames_to_column(mtcars, var="das_Auto") %>% head

Gives:

           das_Auto  mpg cyl disp  hp drat    wt  qsec vs am gear carb
1         Mazda RX4 21.0   6  160 110 3.90 2.620 16.46  0  1    4    4
2     Mazda RX4 Wag 21.0   6  160 110 3.90 2.875 17.02  0  1    4    4
3        Datsun 710 22.8   4  108  93 3.85 2.320 18.61  1  1    4    1
4    Hornet 4 Drive 21.4   6  258 110 3.08 3.215 19.44  1  0    3    1
5 Hornet Sportabout 18.7   8  360 175 3.15 3.440 17.02  0  0    3    2

In practice, you will often want to act differently depending on whether a variable is an Array or a Hash, not just mere tell. In this situation, an elegant idiom is the following:

case item
  when Array
   #do something
  when Hash
   #do something else
end

Note that you don't call the .class method on item.

You can check the User-Agent string. In JavaScript, that's really easy, it's just a property of the navigator object.

var useragent = navigator.userAgent;

You can check if the device if iPhone or Blackberry in JS with something like

var isIphone = !!agent.match(/iPhone/i),
    isBlackberry = !!agent.match(/blackberry/i);

if isIphone is true you are accessing the site from an Iphone, if isBlackBerry you are accessing the site from a Blackberry.

You can use "UserAgent Switcher" plugin for firefox to test that.

If you are also interested, it may be worth it checking out my script "redirection_mobile.js" hosted on github here https://github.com/sebarmeli/JS-Redirection-Mobile-Site and you can read more details in one of my article here:

http://blog.sebarmeli.com/2010/11/02/how-to-redirect-your-site-to-a-mobile-version-through-javascript/

First you need to sort your array using:

Collections.sort(myArray);

Then you need to reverse the order from ascending to descending using:

Collections.reverse(myArray);

For python2, It's better to use e.message to get the exception message, this will avoid possible UnicodeDecodeError. But yes e.message will be empty for some kind of exceptions like OSError, in which case we can add a exc_info=True to our logging function to not miss the error.
For python3, I think it's safe to use str(e).

Just had same issue. In Python 3, Binary modes 'wb', 'rb' must be specified whereas in Python 2x, they are not needed. When you follow tutorials that are based on Python 2x, that's why you are here.

import pickle

class MyUser(object):
    def __init__(self,name):
        self.name = name

user = MyUser('Peter')

print("Before serialization: ")
print(user.name)
print("------------")
serialized = pickle.dumps(user)
filename = 'serialized.native'

with open(filename,'wb') as file_object:
    file_object.write(serialized)

with open(filename,'rb') as file_object:
    raw_data = file_object.read()

deserialized = pickle.loads(raw_data)


print("Loading from serialized file: ")
user2 = deserialized
print(user2.name)
print("------------")

You would basically want something along the lines of:

SELECT e.*, v.Score
  FROM Evaluation e
LEFT JOIN Value v
ON v.CaseNum = e.CaseNum AND
v.FileNum = e.FileNum AND
v.ActivityNum = e.ActivityNum;

I tried the answer described here but it doesn´t worked for me. I have the last Android SDK tools ver. 23.0.2 and Android SDK Platform-tools ver. 20

The support library android-support-v4.jar is causing this conflict, just delete the library under /libs folder of your project, don´t be scared, the library is already contained in the library appcompat_v7, clean and build your project, and your project will work like a charm!

If you are on MAMP

Check your port number as well generally it is

Host localhost

Port 8889

User root

Password root

Socket /Applications/MAMP/tmp/mysql/mysql.sock

The problem is probably somewhere else. Try this code for example:

Sub test()

  origNum = "006260006"
  creditOrDebit = "D"

  If (origNum = "006260006" Or origNum = "30062600006") And creditOrDebit = "D" Then
    MsgBox "OK"
  End If

End Sub

And you will see that your Or works as expected. Are you sure that your ElseIf statement is executed (it will not be executed if any of the if/elseif before is true)?

I had this too, after running brew install yarn yesterday. At least, everything was fine up until then.

I ran rm -rf node_modules and tried to reinstall, but no npm command was working.

In the end I took the rather simple step of reinstalling Node via the official Node installer for Mac OS X.

https://nodejs.org/en/download/

Everything is fine now. Just went back to the directory, ran npm install and it's done the trick.
