Programs & Examples On #Ecopy

I would suggest TARGET_FILE_DIR if you want the file to be copied to the same folder as your .exe file.

$ Directory of main file (.exe, .so.1.2, .a).

add_custom_command(
  TARGET ${PROJECT_NAME} POST_BUILD
  COMMAND ${CMAKE_COMMAND} -E copy 
    ${CMAKE_CURRENT_SOURCE_DIR}/input.txt 
    $<TARGET_FILE_DIR:${PROJECT_NAME}>)

In VS, this cmake script will copy input.txt to the same file as your final exe, no matter it's debug or release.

If you want to use Imagick out of the box (included with most PHP distributions), it's as easy as...

$image = new Imagick();
$image_filehandle = fopen('some/file.jpg', 'a+');
$image->readImageFile($image_filehandle);

$image->scaleImage(100,200,FALSE);

$image_icon_filehandle = fopen('some/file-icon.jpg', 'a+');
$image->writeImageFile($image_icon_filehandle);

You will probably want to calculate width and height more dynamically based on the original image. You can get an image's current width and height, using the above example, with $image->getImageHeight(); and $image->getImageWidth();

To check for the existence of a directory using Dir, you need to specify vbDirectory as the second argument, as in something like:

If Dir("C:\2013 Recieved Schedules" & "\" & client, vbDirectory) = "" Then

Note that, with vbDirectory, Dir will return a non-empty string if the specified path already exists as a directory or as a file (provided the file doesn't have any of the read-only, hidden, or system attributes). You could use GetAttr to be certain it's a directory and not a file.

Attributed String Programming Guide:

UIFont *font = [UIFont fontWithName:@"Palatino-Roman" size:14.0];
NSDictionary *attrsDictionary = [NSDictionary dictionaryWithObject:font
                                forKey:NSFontAttributeName];
NSAttributedString *attrString = [[NSAttributedString alloc] initWithString:@"strigil" attributes:attrsDictionary];

Update: I tried to use addAttribute: method in my own app, but it seemed to be not working on the iOS 6 Simulator:

NSLog(@"%@", textView.attributedText);

The log seems to show correctly added attributes, but the view on iOS simulator was not display with attributes.

IF...ELSE IF constructs work very well in batch files, in particular when you use only one conditional expression on each IF line:

IF %F%==1 (
    ::copying the file c to d
    copy "%sourceFile%1" "%destinationFile1%"
) ELSE IF %F%==0 (
    ::moving the file e to f
    move "%sourceFile2%" "%destinationFile2%" )

In your example you use IF...AND...IF type construct, where 2 conditions must be met simultaneously. In this case you can still use IF...ELSE IF construct, but with extra parentheses to avoid uncertainty for the next ELSE condition:

IF %F%==1 (IF %C%==1 (
    ::copying the file c to d
    copy "%sourceFile1%" "%destinationFile1%" )
) ELSE IF %F%==1 (IF %C%==0 (
    ::moving the file e to f
    move "%sourceFile2%" "%destinationFile2%"))

The above construct is equivalent to:

IF %F%==1 (
    IF %C%==1 (
    ::copying the file c to d
    copy "%sourceFile1%" "%destinationFile1%"
    ) ELSE IF %C%==0 (
    ::moving the file e to f
    move "%sourceFile2%" "%destinationFile2%"))

Processing sequence of batch commands depends on CMD.exe parsing order. Just make sure your construct follows that logical order, and as a rule it will work. If your batch script is processed by Cmd.exe without errors, it means this is the correct (i.e. supported by your OS Cmd.exe version) construct, even if someone said otherwise.

You are using ASIHTTPRequest so you need to setup your project. Read the second part here

I used this single line of code to create a new UIImage which is scaled. Set the scale and orientation params to achieve what you want. The first line of code just grabs the image.

    // grab the original image
    UIImage *originalImage = [UIImage imageNamed:@"myImage.png"];
    // scaling set to 2.0 makes the image 1/2 the size. 
    UIImage *scaledImage = 
                [UIImage imageWithCGImage:[originalImage CGImage] 
                              scale:(originalImage.scale * 2.0)
                                 orientation:(originalImage.imageOrientation)];

If you are trying to generate thumbnails, you must first resize the image using imagecopyresampled();. You must resize the image so that the size of the smaller side of the image is equal to the corresponding side of the thumb.

For example, if your source image is 1280x800px and your thumb is 200x150px, you must resize your image to 240x150px and then crop it to 200x150px. This is so that the aspect ratio of the image won't change.

Here's a general formula for creating thumbnails:

$image = imagecreatefromjpeg($_GET['src']);
$filename = 'images/cropped_whatever.jpg';

$thumb_width = 200;
$thumb_height = 150;

$width = imagesx($image);
$height = imagesy($image);

$original_aspect = $width / $height;
$thumb_aspect = $thumb_width / $thumb_height;

if ( $original_aspect >= $thumb_aspect )
{
   // If image is wider than thumbnail (in aspect ratio sense)
   $new_height = $thumb_height;
   $new_width = $width / ($height / $thumb_height);
}
else
{
   // If the thumbnail is wider than the image
   $new_width = $thumb_width;
   $new_height = $height / ($width / $thumb_width);
}

$thumb = imagecreatetruecolor( $thumb_width, $thumb_height );

// Resize and crop
imagecopyresampled($thumb,
                   $image,
                   0 - ($new_width - $thumb_width) / 2, // Center the image horizontally
                   0 - ($new_height - $thumb_height) / 2, // Center the image vertically
                   0, 0,
                   $new_width, $new_height,
                   $width, $height);
imagejpeg($thumb, $filename, 80);

Haven't tested this but it should work.

EDIT

Now tested and working.

In IE you have to use attachEvent rather than the standard addEventListener.

A common practice is to check if the addEventListener method is available and use it, otherwise use attachEvent:

if (el.addEventListener){
  el.addEventListener('click', modifyText, false); 
} else if (el.attachEvent){
  el.attachEvent('onclick', modifyText);
}

You can make a function to do it:

function bindEvent(el, eventName, eventHandler) {
  if (el.addEventListener){
    el.addEventListener(eventName, eventHandler, false); 
  } else if (el.attachEvent){
    el.attachEvent('on'+eventName, eventHandler);
  }
}
// ...
bindEvent(document.getElementById('myElement'), 'click', function () {
  alert('element clicked');
});

You can run an example of the above code here.

The third argument of addEventListener is useCapture; if true, it indicates that the user wishes to initiate event capturing.

you are asking about Geocoder. Google provide an API for this. so does another provider for this.

For me the major difference is all the ancilliary files that TFS will add to your solution (.vssscc) to 'support' TFS - we've had recent issues with these files ending up mapped to the wrong branch, which lead to some interesting debugging...

if it's background, use background-size: cover;

body{_x000D_
    background-image: url('http://i.stack.imgur.com/kx8MT.gif');_x000D_
    background-size: cover;_x000D_
    _x000D_
    _x000D_
    _x000D_
    height: 100vh;_x000D_
    padding:0;_x000D_
    margin:0;_x000D_
}

@adeneo answer works for Firefox and chrome... For IE the below can be used.

if (window.navigator.msSaveOrOpenBlob) {_x000D_
  var blob = new Blob([decodeURIComponent(encodeURI(result.data))], {_x000D_
    type: "text/csv;charset=utf-8;"_x000D_
  });_x000D_
  navigator.msSaveBlob(blob, 'FileName.csv');_x000D_
}

Usually, we define classes for this.

class XClass( object ):
   def __init__( self ):
       self.myAttr= None

x= XClass()
x.myAttr= 'magic'
x.myAttr

However, you can, to an extent, do this with the setattr and getattr built-in functions. However, they don't work on instances of object directly.

>>> a= object()
>>> setattr( a, 'hi', 'mom' )
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'object' object has no attribute 'hi'

They do, however, work on all kinds of simple classes.

class YClass( object ):
    pass

y= YClass()
setattr( y, 'myAttr', 'magic' )
y.myAttr

Don't forget to seed the RNG with srand() first.

I was trying the git push --all bitbucket call and it was throwing back the "fatal: Authentication failed for 'https://..." response. The solution that worked for me was to change the command to:

git push --all https://{username}@{url}

On Windows, this popped up a dialog that allowed me to enter my password and the push worked.

Use an empty object literal isn't necessary here, you can use null or undefined:

$scope.items = null;

In this way, ng-show should keep working, and in your controller you can just do:

if ($scope.items) {
    // items have value
} else {
    // items is still null
}

And in your $http callbacks, you do the following:

$http.get(..., function(data) {
    $scope.items = {
        data: data,
        // other stuff
    };
});

These answers do help explain this, but it still isn't perfectly intuitive for a non-programmer (i.e. someone like me who is learning Python for the first time in context of data science coursework). I still find using the terms "along" or "for each" wrt to rows and columns to be confusing.

What makes more sense to me is to say it this way:

• Axis 0 will act on all the ROWS in each COLUMN
• Axis 1 will act on all the COLUMNS in each ROW

So a mean on axis 0 will be the mean of all the rows in each column, and a mean on axis 1 will be a mean of all the columns in each row.

Ultimately this is saying the same thing as @zhangxaochen and @Michael, but in a way that is easier for me to internalize.

The root directory of a web application has a special significance and certain content can be present on in that folder. It can have a special file called as “Global.asax”. ASP.Net framework uses the content in the global.asax and creates a class at runtime which is inherited from HttpApplication. During the lifetime of an application, ASP.NET maintains a pool of Global.asax derived HttpApplication instances. When an application receives an http request, the ASP.Net page framework assigns one of these instances to process that request. That instance is responsible for managing the entire lifetime of the request it is assigned to and the instance can only be reused after the request has been completed when it is returned to the pool. The instance members in Global.asax cannot be used for sharing data across requests but static member can be. Global.asax can contain the event handlers of HttpApplication object and some other important methods which would execute at various points in a web application

Push object into your array. Try this:

export class FormComponent implements OnInit {
    name: string;
    empoloyeeID : number;
    empList: Array<{name: string, empoloyeeID: number}> = []; 
    constructor() {}
    ngOnInit() {}
    onEmpCreate(){
        console.log(this.name,this.empoloyeeID);
        this.empList.push({ name: this.name, empoloyeeID: this.empoloyeeID });
        this.name = "";
        this.empoloyeeID = 0;
    }
}

import shutil 
import os 
import logging

source = '/var/spools/asterisk/monitor' 
dest1 = '/tmp/'

logging.basicConfig(filename='app.log', filemode='w', format='%(name)s

logging.info('directories moved')

A little bit cooked code with log feature. You can also configure this to run at some period of time using crontab.

Instead of recommending the usual "turn off the JSHint globals", I recommend using the module pattern to fix this problem. It keeps your code "contained" and gives a performance boost (based on Paul Irish's "10 things I learned about Jquery").

I tend to write my module patterns like this:

(function (window) {
    // Handle dependencies
    var angular = window.angular,
        $ = window.$,
        document = window.document;

    // Your application's code
}(window))

You can get these other performance benefits (explained more here):

• When minifying code, the passed in window object declaration gets minified as well. e.g. window.alert() become m.alert().
• Code inside the self-executing anonymous function only uses 1 instance of the window object.
• You cut to the chase when calling in a window property or method, preventing expensive traversal of the scope chain e.g. window.alert() (faster) versus alert() (slower) performance.
• Local scope of functions through "namespacing" and containment (globals are evil). If you need to break up this code into separate scripts, you can make a submodule for each of those scripts, and have them imported into one main module.

I am assuming you mean using XSD files. Surprisingly there aren't many python XML libraries that support this. lxml does however. Check Validation with lxml. The page also lists how to use lxml to validate with other schema types.

No, it's not possible. If it runs on the client browser, it must be downloaded by the client browser. It's pretty trivial to use Fiddler to inspect the HTTP session and get any downloaded js files.

There are tricks you can use. One of the most obvious is to employ a javascript obfuscator.

Then again, obfuscation only prevents casual snooping, and doesnt prevent people from lifting and using your code.

You can try compiled action script in the form of a flash movie.

You can use an array

$something = array(
   'key' => 'value',
   'key2' => 'value2'
);

or with standard object.

$something = new StdClass();

$something->key = 'value';
$something->key2 = 'value2';

You just need to run:
$ set +o history

To see more, run:
$ man set

As well as /etc/profile which others have mentioned, some Linux systems now use a directory /etc/profile.d/; any .sh files in there will be sourced by /etc/profile. It's slightly neater to keep your custom environment stuff in these files than to just edit /etc/profile.

Use the propfull keyword.

It will generate a property and a variable.

Type keyword propfull in the editor, followed by two TABs. It will generate code like:

private data_type var_name;

public data_type var_name1{ get;set;}

Video demonstrating the use of snippet 'propfull' (among other things), at 4 min 11 secs.

Consider fwrite():

<?php
$fp = fopen('lidn.txt', 'w');
fwrite($fp, 'Cats chase mice');
fclose($fp);
?>

Function Pointers can have very different sizes, from 4 to 20 Bytes on an X86 machine, depending on the compiler. So the answer is NO - sizes can vary.

Another example: take an 8051 program, it has three memory ranges and thus has three different pointer sizes, from 8 bit, 16bit, 24bit, depending on where the target is located, even though the target's size is always the same (e.g. char).

I have used a different USB cable and it started working. This is weird because the USB cable (which was not detected in android studio) was charging the phone. This made me feel like there was a problem on my Mac.

However changing the cable worked for me. Just check this option as well if you got stuck with this problem.

Answers suggesting to disable CURLOPT_SSL_VERIFYPEER should not be accepted. The question is "Why doesn't it work with cURL", and as correctly pointed out by Martijn Hols, it is dangerous.

The error is probably caused by not having an up-to-date bundle of CA root certificates. This is typically a text file with a bunch of cryptographic signatures that curl uses to verify a host’s SSL certificate.

You need to make sure that your installation of PHP has one of these files, and that it’s up to date (otherwise download one here: http://curl.haxx.se/docs/caextract.html).

Then set in php.ini:

curl.cainfo = <absolute_path_to> cacert.pem

If you are setting it at runtime, use:

curl_setopt ($ch, CURLOPT_CAINFO, dirname(__FILE__)."/cacert.pem");

git add -u

-u --update Only match against already tracked files in the index rather than the working tree. That means that it will never stage new files, but that it will stage modified new contents of tracked files and that it will remove files from the index if the corresponding files in the working tree have been removed.

If no is given, default to "."; in other words, update all tracked files in the current directory and its subdirectories.

Using Google Collections, assuming K is your key type:

Maps.filterKeys(treeMap, new Predicate<K>() {
  @Override
  public boolean apply(K key) {
    return false; //return true here if you need the entry to be in your new map
  }});

You can use filterEntries instead if you need the value as well.

There is a fs.readFileSync( path, options ) method, which is synchronous.

there are lots of compression methods that work recursively command line and its good to know who the end audience is.

i.e. if it is to be sent to someone running windows then zip would probably be best:

zip -r file.zip folder_to_zip

unzip filenname.zip

for other linux users or your self tar is great

tar -cvzf filename.tar.gz folder

tar -cvjf filename.tar.bz2 folder  # even more compression

#change the -c to -x to above to extract

One must be careful with tar and how things are tarred up/extracted, for example if I run

cd ~
tar -cvzf passwd.tar.gz /etc/passwd
tar: Removing leading `/' from member names
/etc/passwd


pwd

/home/myusername

tar -xvzf passwd.tar.gz

this will create /home/myusername/etc/passwd

unsure if all versions of tar do this:

 Removing leading `/' from member names

In your specific case, you can set the containing a element to be:

a {
    display: block;
    text-align: center;
}

One thing .attr() can do that .prop() can't: affect CSS selectors

Here's an issue I didn't see in the other answers.

CSS selector [name=value]

• will respond to .attr('name', 'value')
• but not always to .prop('name', 'value')

.prop() affects only a few attribute-selectors

• input[name] (thanks @TimDown)

.attr() affects all attribute-selectors

• input[value]
• input[naame]
• span[name]
• input[data-custom-attribute] (neither will .data('custom-attribute') affect this selector)

    string fileAndPath = @"c:\webserver\public\myCompany\configs\promo.xml";

    string currentDirectory = Path.GetDirectoryName(fileAndPath);

    string fullPathOnly = Path.GetFullPath(currentDirectory);

currentDirectory: c:\webserver\public\myCompany\configs

fullPathOnly: c:\webserver\public\myCompany\configs

A slight variation on glenn jackman's answer using paste: if the value for the -d delimiter option contains more than one character, paste cycles through the characters one by one, and combined with the -s options keeps doing that while processing the same input file.

This means that we can use whatever we want to have as the separator plus the escape sequence \n to merge two lines at a time.

Using a comma:

$ paste -s -d ',\n' infile
KEY 4048:1736 string,3
KEY 0:1772 string,1
KEY 4192:1349 string,1
KEY 7329:2407 string,2
KEY 0:1774 string,1

and the dollar sign:

$ paste -s -d '$\n' infile
KEY 4048:1736 string$3
KEY 0:1772 string$1
KEY 4192:1349 string$1
KEY 7329:2407 string$2
KEY 0:1774 string$1

What this cannot do is use a separator consisting of multiple characters.

As a bonus, if the paste is POSIX compliant, this won't modify the newline of the last line in the file, so for an input file with an odd number of lines like

KEY 4048:1736 string
3
KEY 0:1772 string

paste won't tack on the separation character on the last line:

$ paste -s -d ',\n' infile
KEY 4048:1736 string,3
KEY 0:1772 string

Try to add this:

^[^a-zA-Z\d\s:]*$

This has worked for me... :)

window.open didn't work for me... just a blank page rendered... but I was able to make the png appear on the page by replacing the src attribute of a pre-existing img element created as the target.

$("#btn_screenshot").click(function(){_x000D_
     element_to_png("container", "testhtmltocanvasimg");_x000D_
});_x000D_
_x000D_
_x000D_
function element_to_png(srcElementID, targetIMGid){_x000D_
    console.log("element_to_png called for element id " + srcElementID);_x000D_
    html2canvas($("#"+srcElementID)[0]).then( function (canvas) {_x000D_
        var myImage = canvas.toDataURL("image/png");_x000D_
        $("#"+targetIMGid).attr("src", myImage);_x000D_
  console.log("html2canvas completed.  png rendered to " + targetIMGid);_x000D_
    });_x000D_
}

<div id="testhtmltocanvasdiv" class="mt-3">_x000D_
   <img src="" id="testhtmltocanvasimg">_x000D_
</div>

I can then right-click on the rendered png and "save as". May be just as easy to use the "snipping tool" to capture the element, but html2canvas is an certainly an interesting bit of code!

In IIS you can declare the mime type for WOFF2 font files by adding the following to your project's web.config:

<system.webServer>
  <staticContent>
    <remove fileExtension=".woff2" />
    <mimeMap fileExtension=".woff2" mimeType="font/woff2" />
  </staticContent>
</system.webServer>

Update: The mime type may be changing according to the latest W3C Editor's Draft WOFF2 spec. See Appendix A: Internet Media Type Registration section 6.5. WOFF 2.0 which states the latest proposed format is font/woff2

Swift 3/4 with @IBDesignable

While almost all the above solutions work fine but I would suggest an @IBDesignable custom class for this.

@IBDesignable
class CustomLabel: UILabel {

    /*
    // Only override draw() if you perform custom drawing.
    // An empty implementation adversely affects performance during animation.
    override func draw(_ rect: CGRect) {
        // Drawing code
    }
    */

    @IBInspectable var borderColor: UIColor = UIColor.white {
        didSet {
            layer.borderColor = borderColor.cgColor
        }
    }

    @IBInspectable var borderWidth: CGFloat = 2.0 {
        didSet {
            layer.borderWidth = borderWidth
        }
    }

    @IBInspectable var cornerRadius: CGFloat = 0.0 {
        didSet {
            layer.cornerRadius = cornerRadius
        }
    }
}

The original post was asking how to center the collapsed navbar. To center elements on the normal navbar, try this:

}

.navbar-nav > li {

So, eventually I did that thing that all developers hate doing. I went and checked the server log files and found a report of a syntax error in line n.

tail -n 20 /var/log/apache2/error.log

Using Date object guarantees that. For eg if you try to create April 31st :

new Date(2014,3,31)        // Thu May 01 2014 00:00:00

Please note that it's zero indexed, so Jan. is 0, Feb. is 1 etc.

A bootstrap v3 solution (where the events have different names), also using only one jQuery selector (as seen here):

$('.accordion').on('hide.bs.collapse show.bs.collapse', function (n) {
    $(n.target).siblings('.panel-heading').find('i.glyphicon').toggleClass('glyphicon-chevron-down glyphicon-chevron-up');
});

Be careful where you set WORKDIR because it can affect the continuous integration flow. For example, setting it to /home/circleci/project will cause error something like .ssh or whatever is the remote circleci is doing at setup time.

python3: Google "list comphrension" if the square bracket syntax is new to you.

 with open('data.txt') as f:
     lines = [ line.strip( ) for line in list(f) ]

This is what I am using,

Intent intent = new Intent(android.content.Intent.ACTION_VIEW, 
Uri.parse("http://maps.google.com/maps?saddr="+latitude_cur+","+longitude_cur+"&daddr="+latitude+","+longitude));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addCategory(Intent.CATEGORY_LAUNCHER );     
intent.setClassName("com.google.android.apps.maps", "com.google.android.maps.MapsActivity");
startActivity(intent);

From here (Google is your friend):

In a DTD, PCDATA and CDATA are used to assert something about the allowable content of elements and attributes, respectively. In an element's content model, #PCDATA says that the element contains (may contain) "any old text." (With exceptions as noted below.) In an attribute's declaration, CDATA is one sort of constraint you can put on the attribute's allowable values (other sorts, all mutually exclusive, include ID, IDREF, and NMTOKEN). An attribute whose allowable values are CDATA can (like PCDATA in an element) contain "any old text."

A potentially really confusing issue is that there's another "CDATA," also referred to as marked sections. A marked section is a portion of element (#PCDATA) content delimited with special strings: to close it. If you remember that PCDATA is "parsed character data," a CDATA section is literally the same thing, without the "parsed." Parsers transmit the content of a marked section to downstream applications without hiccupping every time they encounter special characters like < and &. This is useful when you're coding a document that contains lots of those special characters (like scripts and code fragments); it's easier on data entry, and easier on reading, than the corresponding entity reference.

So you can infer that the exception to the "any old text" rule is that PCDATA cannot include any of these unescaped special characters, UNLESS they fall within the scope of a CDATA marked section.

It's a great idea to use cURL as suggested by rojoca.

Here is an example. You can monitor text.txt while the script is running in background:

<?php

function doCurl($begin)
{
    echo "Do curl<br />\n";
    $url = 'http://'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
    $url = preg_replace('/\?.*/', '', $url);
    $url .= '?begin='.$begin;
    echo 'URL: '.$url.'<br>';
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $result = curl_exec($ch);
    echo 'Result: '.$result.'<br>';
    curl_close($ch);
}


if (empty($_GET['begin'])) {
    doCurl(1);
}
else {
    while (ob_get_level())
        ob_end_clean();
    header('Connection: close');
    ignore_user_abort();
    ob_start();
    echo 'Connection Closed';
    $size = ob_get_length();
    header("Content-Length: $size");
    ob_end_flush();
    flush();

    $begin = $_GET['begin'];
    $fp = fopen("text.txt", "w");
    fprintf($fp, "begin: %d\n", $begin);
    for ($i = 0; $i < 15; $i++) {
        sleep(1);
        fprintf($fp, "i: %d\n", $i);
    }
    fclose($fp);
    if ($begin < 10)
        doCurl($begin + 1);
}

?>

Why to complicate the scenario? Its very simple and straight forward

1. Convert list to set - removes duplicates
2. Convert set to list again - which gives list in ascending order

Here is a code

mlist = [2, 3, 6, 6, 5]
mlist = list(set(mlist))
print mlist[-2]

I use HAVING for constraining a query based on the results of an aggregate function. E.G. select * in blahblahblah group by SOMETHING having count(SOMETHING)>0

You can use:

type text1.txt >> combine.txt
echo >> combine.txt
type text2.txt >> combine.txt

or something like this:

echo blah >> combine.txt
echo blah2 >> combine.txt
echo >> combine.txt
echo other >> combine.txt

One more answer to improve on: https://stackoverflow.com/a/4203897/2804197 and https://stackoverflow.com/a/25476462/1338797 (Tkinter).

Tkinter is nice, because it's either included with Python (Windows) or easy to install (Linux), and thus requires little dependencies for the end user.

Here I have a "full-blown" example, which copies the arguments or the standard input, to clipboard, and - when not on Windows - waits for the user to close the application:

import sys

try:
    from Tkinter import Tk
except ImportError:
    # welcome to Python3
    from tkinter import Tk
    raw_input = input

r = Tk()
r.withdraw()
r.clipboard_clear()

if len(sys.argv) < 2:
    data = sys.stdin.read()
else:
    data = ' '.join(sys.argv[1:])

r.clipboard_append(data)

if sys.platform != 'win32':
    if len(sys.argv) > 1:
        raw_input('Data was copied into clipboard. Paste and press ENTER to exit...')
    else:
        # stdin already read; use GUI to exit
        print('Data was copied into clipboard. Paste, then close popup to exit...')
        r.deiconify()
        r.mainloop()
else:
    r.destroy()

This showcases:

• importing Tk across Py2 and Py3
• raw_input and print() compatibility
• "unhiding" Tk root window when needed
• waiting for exit on Linux in two different ways.

Most of the answers here are way more complicated than they have to be. If you just want to copy the database of your app from your phone to your computer then you just need this command:

adb -d shell "run-as your.package.name cat databases/database.name" > target.sqlite

All you need to fill in in the above command is the package name of your app, what the database is called and optionally what/where you want the database to be copied to.

_{Please note that this specific command will only work if you have only one device connected to your computer. The -d parameter means that the only connected device will be targeted. But there are other parameters which you can use instead:}

• -e will target the only running emulator
• -s <serialnumber> will target a device with a specific serial number.

FYI, if you want to create an Installer package in VS2010, unfortunately it only targets .NET 4. To work around this, you have to add NET 4.5 as a launch condition.

Add the following in to the Launch Conditions of the installer (Right click, View, Launch Conditions).

In "Search Target Machine", right click and select "Add Registry Search".

Property: REGISTRYVALUE1
RegKey: Software\Microsoft\NET Framework Setup\NDP\v4\Full
Root: vsdrrHKLM
Value: Release

Add new "Launch Condition":

Condition: REGISTRYVALUE1>="#378389"
InstallUrl: http://www.microsoft.com/en-gb/download/details.aspx?id=30653
Message: Setup requires .NET Framework 4.5 to be installed.

Where:

378389 = .NET Framework 4.5

378675 = .NET Framework 4.5.1 installed with Windows 8.1

378758 = .NET Framework 4.5.1 installed on Windows 8, Windows 7 SP1, or Windows Vista SP2

379893 = .NET Framework 4.5.2

Launch condition reference: http://msdn.microsoft.com/en-us/library/vstudio/xxyh2e6a(v=vs.100).aspx

You can also use &, | (and/or) for more flexibility:

values between 5 and 10: A[(A>5)&(A<10)]

values greater than 10 or smaller than 5: A[(A<5)|(A>10)]

Simply restarting Visual Studio worked for me.

Also it depends if you need to use a table element or not. You can imitate a table using CSS and make an A element the row

<div class="table" style="width:100%;">
  <a href="#" class="tr">
    <span class="td">
      cell 1
    </span>
    <span class="td">
      cell 2
    </span>
  </a>
</div>

css:

.table{display:table;}
.tr{display:table-row;}
.td{display:table-cell;}
.tr:hover{background-color:#ccc;}

The accepted answer from Konstantin worked, but there were a few additional steps. After restarting Eclipse, you still have to go into software updates, find your newly available software, check the box(es) for it, and click the "install" button. Then it'll prompt you to restart again and only then will you see your new views or functionality.

Additionally, you can check the "Error Log" view for any problems with your new plugin that eclipse is complaining about.

Handle SIGPIPE Locally

It's usually best to handle the error locally rather than in a global signal event handler since locally you will have more context as to what's going on and what recourse to take.

I have a communication layer in one of my apps that allows my app to communicate with an external accessory. When a write error occurs I throw and exception in the communication layer and let it bubble up to a try catch block to handle it there.

Code:

The code to ignore a SIGPIPE signal so that you can handle it locally is:

// We expect write failures to occur but we want to handle them where 
// the error occurs rather than in a SIGPIPE handler.
signal(SIGPIPE, SIG_IGN);

This code will prevent the SIGPIPE signal from being raised, but you will get a read / write error when trying to use the socket, so you will need to check for that.

Here is the c# implementation of the this forumula

 public class DistanceAlgorithm
{
    const double PIx = 3.141592653589793;
    const double RADIO = 6378.16;

    /// <summary>
    /// This class cannot be instantiated.
    /// </summary>
    private DistanceAlgorithm() { }

    /// <summary>
    /// Convert degrees to Radians
    /// </summary>
    /// <param name="x">Degrees</param>
    /// <returns>The equivalent in radians</returns>
    public static double Radians(double x)
    {
        return x * PIx / 180;
    }

    /// <summary>
    /// Calculate the distance between two places.
    /// </summary>
    /// <param name="lon1"></param>
    /// <param name="lat1"></param>
    /// <param name="lon2"></param>
    /// <param name="lat2"></param>
    /// <returns></returns>
    public static double DistanceBetweenPlaces(
        double lon1,
        double lat1,
        double lon2,
        double lat2)
    {
        double dlon =  Radians(lon2 - lon1);
        double dlat =  Radians(lat2 - lat1);

        double a = (Math.Sin(dlat / 2) * Math.Sin(dlat / 2)) + Math.Cos(Radians(lat1)) * Math.Cos(Radians(lat2)) * (Math.Sin(dlon / 2) * Math.Sin(dlon / 2));
        double angle = 2 * Math.Atan2(Math.Sqrt(a), Math.Sqrt(1 - a));
        return (angle * RADIO) * 0.62137;//distance in miles
    }

}    

Always, always, always put disposable objects inside of using statements. I can't see how you've instantiated your DataReader but you should do it like this:

using (Connection c = ...)
{
    using (DataReader dr = ...)
    {
        //Work with dr in here.
    }
}
//Now the connection and reader have been closed and disposed.

Now, to answer your question, the reader is using the same connection as the command you're trying to ExecuteNonQuery on. You need to use a separate connection since the DataReader keeps the connection open and reads data as you need it.

List is an interface. Interfaces cannot be instantiated. Only concrete types can be instantiated. You probably want to use an ArrayList, which is an implementation of the List interface.

List<Product> products = new ArrayList<Product>();

1. Select cell B3 and click the Conditional Formatting button in the ribbon and choose "New Rule".
2. Select "Use a formula to determine which cells to format"
3. Enter the formula: =IF(B2="X",IF(B3="Y", TRUE, FALSE),FALSE), and choose to fill green when this is true
4. Create another rule and enter the formula =IF(B2="X",IF(B3="W", TRUE, FALSE),FALSE) and choose to fill red when this is true.

More details - conditional formatting with a formula applies the format when the formula evaluates to TRUE. You can use a compound IF formula to return true or false based on the values of any cells.

Another option: =MID(A1,2,LEN(A1)-2)

Or this (for fun): =RIGHT(LEFT(A1,LEN(A1)-1),LEN(LEFT(A1,LEN(A1)-1))-1)

The command has to be entered in the directory of the repository. The error is complaining that your current directory isn't a git repo

1. Are you in the right directory? Does typing ls show the right files?
2. Have you initialized the repository yet? Typed git init? (git-init documentation)

Either of those would cause your error.

ffmpeg provides this functionality. All you need to do is run someting like

ffmpeg -i <inputfilename> -s 640x480 -b 512k -vcodec mpeg1video -acodec copy <outputfilename>

For newer versions of ffmpeg you need to change -b to -b:v:

ffmpeg -i <inputfilename> -s 640x480 -b:v 512k -vcodec mpeg1video -acodec copy <outputfilename>

to convert the input video file to a video with a size of 640 x 480 and a bitrate of 512 kilobits/sec using the MPEG 1 video codec and just copying the original audio stream. Of course, you can plug in any values you need and play around with the size and bitrate to achieve the quality/size tradeoff you are looking for. There are also a ton of other options described in the documentation

Run ffmpeg -formats or ffmpeg -codecs for a list of all of the available formats and codecs. If you don't have to target a specific codec for the final output, you can achieve better compression ratios with minimal quality loss using a state of the art codec like H.264.

I Solved this problem adding @Cascade to the @ManyToOne attribute.

import org.hibernate.annotations.Cascade;
import org.hibernate.annotations.CascadeType;

@ManyToOne
@JoinColumn(name="BLOODGRUPID")
@Cascade({CascadeType.MERGE, CascadeType.SAVE_UPDATE})
private Bloodgroup bloodgroup;

Build your project and get the apk from your_project\app\build\apk

Another formula option is to use REPLACE function to replace the first n characters with nothing, e.g. if n = 4

=REPLACE(A1,1,4,"")

This question has been already answered in Unicode characters in Windows command line - how?

You missed one step -> you need to use Lucida console fonts in addition to executing chcp 65001 from cmd console.

The svnbook has a section on how Subversion allows you to revert the changes from a particular revision without affecting the changes that occured in subsequent revisions:

http://svnbook.red-bean.com/en/1.4/svn.branchmerge.commonuses.html#svn.branchmerge.commonuses.undo

I don't use Eclipse much, but in TortoiseSVN you can do this from the from the log dialogue; simply right-click on the revision you want to revert and select "Revert changes from this revision".

In the case that the files for which you want to revert "bad changes" had "good changes" in subsequent revisions, then the process is the same. The changes from the "bad" revision will be reverted leaving the changes from "good" revisions untouched, however you might get conflicts.

If you use %pylab inline you can (on a new line) insert the following command:

%pylab inline
pylab.rcParams['figure.figsize'] = (10, 6)

This will set all figures in your document (unless otherwise specified) to be of the size (10, 6), where the first entry is the width and the second is the height.

See this SO post for more details. https://stackoverflow.com/a/17231361/1419668

[Column(TypeName = "decimal(18,2)")]

this will work with EF Core code first migrations as described here.

// TypeScript

const today = new Date();
const firstDayOfYear = new Date(today.getFullYear(), 0, 1);

// Explicitly convert Date to Number
const pastDaysOfYear = ( Number(today) - Number(firstDayOfYear) );

In addition set the proxy for the command line session Open a command line where you might want to run your script

netsh winhttp set proxy YourProxySERVER:yourProxyPORT

run your script in that terminal.

import matplotlib.pyplot as plt

fig, ax = plt.subplots(2, 2)

ax[0, 0].plot(range(10), 'r') #row=0, col=0
ax[1, 0].plot(range(10), 'b') #row=1, col=0
ax[0, 1].plot(range(10), 'g') #row=0, col=1
ax[1, 1].plot(range(10), 'k') #row=1, col=1
plt.show()

from eclipse, you can select on the project, right click->team->upgrade

As @Peter Cullen answer mention, your script will meet browser timeout first. So its good idea to provide some log output, then flush(), but connection have buffer and you'll not see anything unless much output provided. Here are code snippet what helps provide reliable log:

set_time_limit(0);
...
print "log message";
print "<!--"; print str_repeat (' ', 4000); print "-->"; flush();
print "log message";
print "<!--"; print str_repeat (' ', 4000); print "-->"; flush();

You can run the sleep command before your ExecStart with ExecStartPre :

[Service]
ExecStartPre=/bin/sleep 30

I was looking for a solution to the opposite problem where I needed a fixed width div in the centre and a fluid width div on either side, so I came up with the following and thought I'd post it here in case anyone needs it.

#wrapper {_x000D_
  clear: both;_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
#wrapper div {_x000D_
  display: inline-block;_x000D_
  height: 500px;_x000D_
}_x000D_
_x000D_
#center {_x000D_
  background-color: green;_x000D_
  margin: 0 auto;_x000D_
  overflow: auto;_x000D_
  width: 500px;_x000D_
}_x000D_
_x000D_
#left {_x000D_
  float: left;_x000D_
}_x000D_
_x000D_
#right {_x000D_
  float: right;_x000D_
}_x000D_
_x000D_
.fluid {_x000D_
  background-color: yellow;_x000D_
  width: calc(50% - 250px);_x000D_
}

<div id="wrapper">_x000D_
  <div id="center">_x000D_
    This is fixed width in the centre_x000D_
  </div>_x000D_
  <div id="left" class="fluid">_x000D_
    This is fluid width on the left_x000D_
  </div>_x000D_
  <div id="right" class="fluid">_x000D_
    This is fluid width on the right_x000D_
  </div>_x000D_
</div>

If you change the width of the #center element then you need to update the width property of .fluid to:

width: calc(50% - [half of center width]px);

(Using system.IO)

You can simply use \n for newline and \t in front of the string to indent it.

For example in c#:

public string theXML() {
    string xml = "";
    xml += "<Scene>\n";
    xml += "\t<Character>\n";


    xml += "\t</Character>\n";
    xml += "</Scene>\n";
    return xml;
}

This will result in the output: http://prntscr.com/96dfqc

As Michael said check the "Requires Full Screen" checkbox under General > Targets

and also delete the 'CFBundleIcons-ipad' from the info.plst

This worked for me

This may be an old question but I have tried this method to remove query params. Seems to work smoothly for me as I needed a reload as well combined with removing of query params.

window.location.href = window.location.origin + window.location.pathname;

Also since I am using simple string addition operation I am guessing the performance will be good. But Still worth comparing with snippets in this answer

Spark 2.2 onwards

df.filter(df.location.contains('google.com'))

Spark 2.2 documentation link

Spark 2.1 and before

You can use plain SQL in filter

df.filter("location like '%google.com%'")

or with DataFrame column methods

df.filter(df.location.like('%google.com%'))

I have a list of color names in range A2:A8, in column B I want to extract a distinct list of color names.

Follow the below given steps:

• Select the Cell B2; write the formula to retrieve the unique values from a list.
• =IF(COUNTIF(A$2:A2,A2)=1,A2,””)
• Press Enter on your keyboard.
• The function will return the name of the first color.
• To return the value for the rest of cells, copy the same formula down. To copy formula in range B3:B8, copy the formula in cell B2 by pressing the key CTRL+C on your keyboard and paste in the range B3:B8 by pressing the key CTRL+V.
• Here you can see the output where we have the unique list of color names.

Here's what I had to do to get this working. This means:

1. Custom UserNamePasswordValidator (no need for a Windows account, SQLServer or ActiveDirectory -- your UserNamePasswordValidator could have username & password hardcoded, or read it from a text file, MySQL or whatever).
2. https
3. IIS7
4. .net 4.0

My site is managed through DotNetPanel. It has 3 security options for virtual directories:

1. Allow Anonymous Access
2. Enable Basic Authentication
3. Enable Integrated Windows Authentication

Only "Allow Anonymous Access" is needed (although, that, by itself wasn't enough).

Setting

proxy.ClientCredentials.Windows.AllowedImpersonationLevel =  System.Security.Principal.TokenImpersonationLevel.Impersonation;

Didn't make a difference in my case.

However, using this binding worked:

      <security mode="TransportWithMessageCredential">
        <transport clientCredentialType="Windows" />
        <message clientCredentialType="UserName" />
      </security>        

The linked list holds operations on the shared data structure.

For example, if I have a stack, it will be manipulated with pushes and pops. The linked list would be a set of pushes and pops on the pseudo-shared stack. Each thread sharing that stack will actually have a local copy, and to get to the current shared state, it'll walk the linked list of operations, and apply each operation in order to its local copy of the stack. When it reaches the end of the linked list, its local copy holds the current state (though, of course, it's subject to becoming stale at any time).

In the traditional model, you'd have some sort of locks around each push and pop. Each thread would wait to obtain a lock, then do a push or pop, then release the lock.

In this model, each thread has a local snapshot of the stack, which it keeps synchronized with other threads' view of the stack by applying the operations in the linked list. When it wants to manipulate the stack, it doesn't try to manipulate it directly at all. Instead, it simply adds its push or pop operation to the linked list, so all the other threads can/will see that operation and they can all stay in sync. Then, of course, it applies the operations in the linked list, and when (for example) there's a pop it checks which thread asked for the pop. It uses the popped item if and only if it's the thread that requested this particular pop.

You can also try -j%NUMBER_OF_PROCESSORS% as an argument it will use all your cores. Makes things super fast on my quad core.

public class Console {

    public static void Log(Object obj){
        System.out.println(obj);
    }
}

to call and use as JavaScript just do this:

Console.Log (Object)

I think that's what you mean

I had this problem, but only in Visual Studio Code, not in ISE. Turns out I was using an x86 session in VSCode. I displayed the PowerShell Session Menu and switched to the x64 session, and all the modules began working without full paths. I am using Version 1.17.2, architecture x64 of VSCode. My modules were stored in the C:\Windows\System32\WindowsPowerShell\v1.0\Modules directory.

Beautiful solution using Reflection.

<?php
class Grandpa 
{
    public function __construct()
    {
        echo "Grandpa's constructor called\n";
    }

}

class Papa extends Grandpa
{
    public function __construct()
    {
        echo "Papa's constructor called\n";

        // call Grandpa's constructor
        parent::__construct();
    }
}

class Kiddo extends Papa
{
    public function __construct()
    {
        echo "Kiddo's constructor called\n";

        $reflectionMethod = new ReflectionMethod(get_parent_class(get_parent_class($this)), '__construct');
        $reflectionMethod->invoke($this);
    }
}

$kiddo = new Kiddo();
$papa = new Papa();

If you have your radios in a container with id = radioButtonContainerId you can still use onClick and then check which one is selected and accordingly run some functions:

$('#radioButtonContainerId input:radio').click(function() {
    if ($(this).val() === '1') {
      myFunction();
    } else if ($(this).val() === '2') {
      myOtherFunction();
    } 
  });

If you want device ID information use TelephonyManager. Here is the link for that :

Go to Manage Jenkins > Configure Global Security and select the Enable Security checkbox.

For the basic username/password authentication, I would recommend selecting Jenkins Own User Database for the security realm and then selecting Logged in Users can do anything or a matrix based strategy (in case when you have multiple users with different permissions) for the Authorization.

You can call dispose() on the current window and setVisible(true) on the one you want to display.

You need to add z-index to the divs, with a positive number for the top div and negative for the div below

As far as I know python will compile all modules you "import". However python will NOT compile a python script run using: "python script.py" (it will however compile any modules that the script imports).

The real questions is why you don't want python to compile the modules? You could probably automate a way of cleaning these up if they are getting in the way.

So many good answers already. Backbone js helps to keep the code organised. Changing the model/collection takes care of the view rendering automaticallty which reduces lot of development overhead.

Even though it provides maximum flexibility for development, developers should be careful to destroy the models and remove the views properly. Otherwise there may be memory leak in the application.

It might help to see your CSS, as it sounds like a rather weird issue. But anyway, if it is happening and all else is good, you could try shifting the hover effect to javascript (you could use jquery as well). Simply, bind to the mouseover or better still mouseenter event and light up your element when the event fires.

Checkout the last example here: http://api.jquery.com/mouseover/, you could use something similar to log when the event fires and take it from there!

Just keep the following in mind.

In IIS if you have a folder for example called Pages with multiple websites in it. Website will inherit settings from the web.config file from the parent directory. So even if the folder page (in this example Pages) isn't a website but contains a web.config file, all websites listed inside of it will inherit the setting.

Google is full of information on this. As Hans Passant said, Form controls are built in to Excel whereas ActiveX controls are loaded separately.

Generally you'll use Forms controls, they're simpler. ActiveX controls allow for more flexible design and should be used when the job just can't be done with a basic Forms control.

Many user's computers by default won't trust ActiveX, and it will be disabled; this sometimes needs to be manually added to the trust center. ActiveX is a microsoft-based technology and, as far as I'm aware, is not supported on the Mac. This is something you'll have to also consider, should you (or anyone you provide a workbook to) decide to use it on a Mac.

...and to prepend (add the beginning of) each line with *,

%s/^/*/g

yield basically makes an IEnumerable<T> method behave similarly to a cooperatively (as opposed to preemptively) scheduled thread.

yield return is like a thread calling a "schedule" or "sleep" function to give up control of the CPU. Just like a thread, the IEnumerable<T> method regains controls at the point immediately afterward, with all local variables having the same values as they had before control was given up.

yield break is like a thread reaching the end of its function and terminating.

People talk about a "state machine", but a state machine is all a "thread" really is. A thread has some state (I.e. values of local variables), and each time it is scheduled it takes some action(s) in order to reach a new state. The key point about yield is that, unlike the operating system threads we're used to, the code that uses it is frozen in time until the iteration is manually advanced or terminated.

$('#datetimepicker').datetimepicker({ 
    minView: 2, 
    pickTime: false, 
    language: 'pt-BR' 
});

Please try if it works for you as well

You can fix your example with the iterator pattern by changing the parametrization of the class:

List<Room> rooms = new ArrayList<Room>();
rooms.add(room1);
rooms.add(room2);
for(Iterator<Room> i = rooms.iterator(); i.hasNext(); ) {
  String item = i.next();
  System.out.println(item);
}

or much simpler way:

List<Room> rooms = new ArrayList<Room>();
rooms.add(room1);
rooms.add(room2);
for(Room room : rooms) {
  System.out.println(room);
}

from python mailing lists: parsing millisecond thread. There is a function posted there that seems to get the job done, although as mentioned in the author's comments it is kind of a hack. It uses regular expressions to handle the exception that gets raised, and then does some calculations.

You could also try do the regular expressions and calculations up front, before passing it to strptime.

You probably should add a private __clone() method to disallow cloning of an instance.

private function __clone() {}

If you don't include this method the following gets possible

$inst1=UserFactory::Instance(); // to stick with the example provided above
$inst2=clone $inst1;

now $inst1 !== $inst2 - they are not the same instance any more.

Found an alternative way to download cocoapods is to download one of the snapshots available here. It is a bit old but the .bz2 compressed file was much faster to download. Once I had downloaded it, I copied it over to ~/.cocoapods/repos/ and then I unzipped it using bzip2 -dk *.bz2.

The unzipping took a while and once it was over, I changed the extension of the newly uncompressed file to .tar and did tar xvf *.tar to unzip that. This will show the list of files being created and will also take a while.

Finally when I ran pod repo list while inside the project folder, it showed the master folder had been added as a repo. Because I still kept getting an error that it was unable to find the specification for the pod I was looking for, I went to the master folder and did git fetch and then git merge. The git fetch took the longest, about an hour at 50 KB/s. I used fetch and merge instead of pull, as I was having issues with it, i.e. fatal: the remote end hung up unexpectedly. It is now up to date and I was able to get the pod I wanted.

Very simple approach is to assume that the entity class in question be represented in database and then in database table would you need index made up of fields of entity class? If answer is yes then implement comparable and use the index field(s) for natural sorting order. In all other cases use comparator.

<script>

function getSummary(id)
{
   $.ajax({

     type: "GET",//post
     url: 'Your URL',
     data: "id="+id, // appears as $_GET['id'] @ ur backend side
     success: function(data) {
           // data is ur summary
          $('#summary').html(data);
     }

   });

}
</script>

I had this issue on the initial view right after the launch screen. The fix for me since I didn't have a segue or logic defined was to switch the presentation from automatic to fullscreen as shown here:

The following works on all browsers for my 200 figures, for any width percentage -- despite being illegal. Jukka said 'Use it anyway.' (The class just floats the image left or right and sets margins.) I can't imagine why this isn't the standard approach!

<img class="fl" width="66%"
src="A-Images/0.5_Saltation.jpg"
alt="Schematic models of chromosomes ..." />

Change the window width and the image scales obligingly.

I can't say it's an appropriate solution but you can try this.

Steps

• I am hoping that you have already cloned your repo.
• Now copy the file somewhere outside of your project.
• Add that filename with a location in gitigonre file.
• Remove that file from your local project.
• Push your code to remote origin.
• And now add that copied file into your project it'll be ignored.

This is just a hack solution if you want to maintain the history and don't to create mass in it.

If you don't want to use this solution please kindly ignore and try to avoid devote it. Because I am really trying to increase my score on this side

Extending from YaroslavGaponov's answer, the simplest implementation is just using Math.random().

Math.random()

Mathematically, the chances of fractions being the same in a real space [0, 1] is theoretically 0. Probability-wise it is approximately close to 0 for a default length of 16 decimals in node.js. And this implementation should also reduce arithmetic overflows as no operations are performed. Also, it is more memory efficient compared to a string as Decimals occupy less memory than strings.

I call this the "Fractional-Unique-ID".

Wrote code to generate 1,000,000 Math.random() numbers and could not find any duplicates (at least for default decimal points of 16). See code below (please provide feedback if any):

random_numbers = [] 
for (i = 0; i < 1000000; i++) { 
   random_numbers.push(Math.random()); 
   //random_numbers.push(Math.random().toFixed(13)) //depends decimals default 16 
} 

if (i === 1000000) { 
   console.log("Before checking duplicate"); 
   console.log(random_numbers.length); 
   console.log("After checking duplicate"); 
   random_set = new Set(random_numbers); // Set removes duplicates
   console.log([...random_set].length); // length is still the same after removing
} 

If I understood your problem correctly, $(this).parents('.box').children('.something1') Is this what you are looking for?

The object exists in some scope, so you can almost always access the variable via this syntax:

var objname = "myobject";
containing_scope_reference[objname].some_property = 'some value';

The only place where this gets tricky is when you are in a closed scope and you want access to a top-level local variable. When you have something like this:

(function(){
    var some_variable = {value: 25};
    var x = "some_variable";
    console.log(this[x], window[x]); // Doesn't work
})();

You can get around that by using eval instead to access the current scope chain ... but I don't recommend it unless you've done a lot of testing and you know that that's the best way to go about things.

(function(){
    var some_variable = {value: 25};
    var x = "some_variable";
    eval(x).value = 42;
    console.log(some_variable); // Works
})();

Your best bet is to have a reference to a name in an always-going-to-be-there object (like this in the global scope or a private top-level variable in a local scope) and put everything else in there.

Thus:

var my_outer_variable = {};
var outer_pointer = 'my_outer_variable';
// Reach my_outer_variable with this[outer_pointer]
// or window[outer_pointer]

(function(){
    var my_inner_scope = {'my_inner_variable': {} };
    var inner_pointer = 'my_inner_variable';
    // Reach my_inner_variable by using
    // my_inner_scope[inner_pointer]
})();

Here is how I did to download quickly with cURL (I'm not sure how many files it can download though) :

setlocal EnableDelayedExpansion

cd where\to\download

set STR=
for /f "skip=2 delims=" %%F in ('P:\curl -l -u user:password ftp://ftp.example.com/directory/anotherone/') do set STR=-O "ftp://ftp.example.com/directory/anotherone/%%F" !STR!
path\to\curl.exe -v -u user:password !STR!

Why skip=2 ? To get ride of . and ..

Why delims= ? To support names with spaces

use this Reload page

success: function(data){
   if(data.success == true){ // if true (1)
      setTimeout(function(){// wait for 5 secs(2)
           location.reload(); // then reload the page.(3)
      }, 5000); 
   }
}

ARM is a RISC (Reduced Instruction Set Computing) architecture while x86 is a CISC (Complex Instruction Set Computing) one.

The core difference between those in this aspect is that ARM instructions operate only on registers with a few instructions for loading and saving data from / to memory while x86 can operate directly on memory as well. Up until v8 ARM was a native 32 bit architecture, favoring four byte operations over others.

So ARM is a simpler architecture, leading to small silicon area and lots of power save features while x86 becoming a power beast in terms of both power consumption and production.

About question on "Is the x86 Architecture specially designed to work with a keyboard while ARM expects to be mobile?". x86 isn't specially designed to work with a keyboard neither ARM for mobile. However again because of the core architectural choices actually x86 also has instructions to work directly with IO while ARM has not. However with specialized IO buses like USBs, need for such features are also disappearing.

If you need a document to quote, this is what Cortex-A Series Programmers Guide (4.0) tells about differences between RISC and CISC architectures:

An ARM processor is a Reduced Instruction Set Computer (RISC) processor.

Complex Instruction Set Computer (CISC) processors, like the x86, have a rich instruction set capable of doing complex things with a single instruction. Such processors often have significant amounts of internal logic that decode machine instructions to sequences of internal operations (microcode).

RISC architectures, in contrast, have a smaller number of more general purpose instructions, that might be executed with significantly fewer transistors, making the silicon cheaper and more power efficient. Like other RISC architectures, ARM cores have a large number of general-purpose registers and many instructions execute in a single cycle. It has simple addressing modes, where all load/store addresses can be determined from register contents and instruction fields.

ARM company also provides a paper titled Architectures, Processors, and Devices Development Article describing how those terms apply to their bussiness.

An example comparing instruction set architecture:

For example if you would need some sort of bytewise memory comparison block in your application (generated by compiler, skipping details), this is how it might look like on x86

repe cmpsb         /* repeat while equal compare string bytewise */

while on ARM shortest form might look like (without error checking etc.)

top:
ldrb r2, [r0, #1]! /* load a byte from address in r0 into r2, increment r0 after */
ldrb r3, [r1, #1]! /* load a byte from address in r1 into r3, increment r1 after */
subs r2, r3, r2    /* subtract r2 from r3 and put result into r2      */
beq  top           /* branch(/jump) if result is zero                 */

which should give you a hint on how RISC and CISC instruction sets differ in complexity.

I will recommend to use an alternative method using seaborn which more powerful tool for data plotting. You can use seaborn scatterplot and define colum 3 as hue and size.

Working code:

import pandas as pd
import seaborn as sns
import numpy as np

#creating sample data 
sample_data={'col_name_1':np.random.rand(20),
      'col_name_2': np.random.rand(20),'col_name_3': np.arange(20)*100}
df= pd.DataFrame(sample_data)
sns.scatterplot(x="col_name_1", y="col_name_2", data=df, hue="col_name_3",size="col_name_3")

Here is an example of using super():

#New-style classes inherit from object, or from another new-style class
class Dog(object):

    name = ''
    moves = []

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

    def moves_setup(self):
        self.moves.append('walk')
        self.moves.append('run')

    def get_moves(self):
        return self.moves

class Superdog(Dog):

    #Let's try to append new fly ability to our Superdog
    def moves_setup(self):
        #Set default moves by calling method of parent class
        super(Superdog, self).moves_setup()
        self.moves.append('fly')

dog = Superdog('Freddy')
print dog.name # Freddy
dog.moves_setup()
print dog.get_moves() # ['walk', 'run', 'fly']. 
#As you can see our Superdog has all moves defined in the base Dog class

        get
        {
            return _clickCommand ?? (_clickCommand = new CommandHandler( MyAction));
        }

    {
        if(message == null)

            return;
        }
        switch (message.ToString())
        {
            case "btnAdd":
                {
                    btnAdd_Click();
                    break;

                    BtnEdit_Click();
                    break;
                }

            default:
                throw new Exception($"Method {message} not defined");
                break;
        }
    }
}

  public class CommandHandler : ICommand

    private Action<object> _action;
    private Func<object, bool> _canExecute;

    /// <summary>

        _action = action;
        _canExecute = canExecute ?? (x => true);
    }
    public CommandHandler(Action<object> action) : this(action, null)

        _action(parameter);
    }
    public void Refresh()

And in xaml:

     <Button
    Command="{Binding ClickCommand}"
    CommandParameter="BtnEdit_Click"/>

I had the same problem... Had to recreate the project from scratch.

Note: my project was created in XCode 3.1 and was linking against a static library that was being built as a subproject (to a common destination). I changed this to build the source instead when I recreated the XCode project in XCode 4.

Now doing a Product/Archive/Share... gets the option of "iOS App Store Package (.ipa)" directly above "Application" (which is now greyed out) and "Archive" (which exports the .xcarchive).

you can do it by Dynamic Web Project –> RightClick –> Java EE Tools –> Generate Deployment Descriptor Stub.

You can change any header or anything in Application_EndRequest() try this

protected void Application_EndRequest()
{
    // removing excessive headers. They don't need to see this.
    Response.Headers.Remove("header_name");
}

is_numeric checks more:

Finds whether the given variable is numeric. Numeric strings consist of optional sign, any number of digits, optional decimal part and optional exponential part. Thus +0123.45e6 is a valid numeric value. Hexadecimal notation (0xFF) is allowed too but only without sign, decimal and exponential part.

It is possible! Yes

In many cases, you might want to use XAMPP with a different PHP version than the one that comes preinstalled. You might do this to get the benefits of a newer version of PHP, or to reproduce bugs using an earlier version of PHP.

To use a different version of PHP with XAMPP, follow these steps:

1. Download a binary build of the PHP version that you wish to use from the PHP website, and extract the contents of the compressed archive file to your XAMPP installation directory (usually, C:\xampp). Ensure that you give it a different directory name to avoid overwriting the existing PHP version. For example, in this tutorial, we’ll call the new directory C:\xampp\php5-6-0. NOTE : Ensure that the PHP build you download matches the Apache build (VC9 or VC11) in your XAMPP platform.

2. Within the new directory, rename the php.ini-development file to php.ini. If you prefer to use production settings, you could instead rename the php.ini-production file to php.ini.

3. Edit the httpd-xampp.conf file in the apache\conf\extra\ subdirectory of your XAMPP installation directory. Within this file, search for all instances of the old PHP directory path and replace them with the path to the new PHP directory created in Step 1. In particular, be sure to change the lines

    LoadFile "/xampp/php/php5ts.dll"
    LoadFile "/xampp/php/libpq.dll"
    LoadModule php5_module "/xampp/php/php5apache2_4.dll"

to

    LoadFile "/xampp/php5-6-0/php5ts.dll"
    LoadFile "/xampp/php5-6-0/libpq.dll"
    LoadModule php5_module "/xampp/php5-6-0/php5apache2_4.dll"

NOTE : Remember to adjust the file and directory paths above to reflect valid paths on your system.

4. Restart your Apache server through the XAMPP control panel for your changes to take effect. The new version of PHP should now be active. To verify this, browse to the URL http://localhost/xampp/phpinfo.php, which displays the output of the phpinfo() command, and check the version number at the top of the page.

Google play finds you as developer via your keystore.

and maybe your country IP is banned on Google when you generate your new keystore.

change your IP Address and generate new keystore, the problem will be fixed.

if you didn't succeed, use another Gmail in Android Studio and generate new keystore.

For nested JSON plain text

db.model.findAll({
  raw : true ,
  nest : true
})

Another way of doing this is by generating the select query. Play with this fiddle.

SELECT CONCAT('SELECT ', group_concat(`COLUMN_NAME` SEPARATOR '+'), ' FROM scorecard') 
FROM  `INFORMATION_SCHEMA`.`COLUMNS` 
WHERE `TABLE_SCHEMA` = (select database()) 
AND   `TABLE_NAME`   = 'scorecard'
AND   `COLUMN_NAME` LIKE 'mark%';

The query above will generate another query that will do the selecting for you.

1. Run the above query.
2. Get the result and run that resulting query.

Sample result:

SELECT mark1+mark2+mark3 FROM scorecard

You won't have to manually add all the columns anymore.

With SimpleDateFormat. And steps are -

1. Create your date pattern string
2. Create SimpleDateFormat Object
3. And parse with it.
4. It will return Date Object.

Recursion? Where do I start, wiki will tell you “it’s the process of repeating items in a self-similar way"

Back in day when I was doing C, C++ recursion was a god send, stuff like "Tail recursion". You'll also find many sorting algorithms use recursion. Quick sort example: http://alienryderflex.com/quicksort/

Recursion is like any other algorithm useful for a specific problem. Perhaps you mightn't find a use straight away or often but there will be problem you’ll be glad it’s available.

class PrintNumberTask implements Runnable {
Integer count;
Object lock;

PrintNumberTask(int i, Object object) {
    this.count = i;
    this.lock = object;
}

@Override
public void run() {
    while (count <= 10) {
        synchronized (lock) {
            if (count % 2 == 0) {
                System.out.println(count);
                count++;
                lock.notify();
                try {
                    lock.wait();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            } else {
                System.out.println(count);
                count++;
                lock.notify();
                try {
                    lock.wait();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

}

One option is to set a cookie in PHP.

For example: a cookie named invalid with the value of $invalid expiring in 1 day:

setcookie('invalid', $invalid, time() + 60 * 60 * 24);

Then read it back out in JS (using the JS Cookie plugin):

var invalid = Cookies.get('invalid');

if(invalid !== undefined) {
    Cookies.remove('invalid');
}

You can now access the value from the invalid variable in JavaScript.

As Yaron mentioned, there isn't any difference between where and filter.

filter is an overloaded method that takes a column or string argument. The performance is the same, regardless of the syntax you use.

We can use explain() to see that all the different filtering syntaxes generate the same Physical Plan. Suppose you have a dataset with person_name and person_country columns. All of the following code snippets will return the same Physical Plan below:

df.where("person_country = 'Cuba'").explain()
df.where($"person_country" === "Cuba").explain()
df.where('person_country === "Cuba").explain()
df.filter("person_country = 'Cuba'").explain()

These all return this Physical Plan:

== Physical Plan ==
*(1) Project [person_name#152, person_country#153]
+- *(1) Filter (isnotnull(person_country#153) && (person_country#153 = Cuba))
   +- *(1) FileScan csv [person_name#152,person_country#153] Batched: false, Format: CSV, Location: InMemoryFileIndex[file:/Users/matthewpowers/Documents/code/my_apps/mungingdata/spark2/src/test/re..., PartitionFilters: [], PushedFilters: [IsNotNull(person_country), EqualTo(person_country,Cuba)], ReadSchema: struct<person_name:string,person_country:string>

The syntax doesn't change how filters are executed under the hood, but the file format / database that a query is executed on does. Spark will execute the same query differently on Postgres (predicate pushdown filtering is supported), Parquet (column pruning), and CSV files. See here for more details.

REST is just a software architecture style for exposing resources.

• Use HTTP methods explicitly.
• Be stateless.
• Expose directory structure-like URIs.
• Transfer XML, JavaScript Object Notation (JSON), or both.

A typical REST call to return information about customer 34456 could look like:

http://example.com/customer/34456

Have a look at the IBM tutorial for REST web services

So from the android developer site on Data Storage:

User Preferences

Shared preferences are not strictly for saving "user preferences," such as what ringtone a user has chosen. If you're interested in creating user preferences for your application, see PreferenceActivity, which provides an Activity framework for you to create user preferences, which will be automatically persisted (using shared preferences).

So I think it is okay since it is simply just key-value pairs which are persisted.

To the original poster, this is not that hard. You simply just iterate through your array list and add the items. In this example I use a map for simplicity but you can use an array list and change it appropriately:

// my list of names, icon locations
Map<String, String> nameIcons = new HashMap<String, String>();
nameIcons.put("Noel", "/location/to/noel/icon.png");
nameIcons.put("Bob", "another/location/to/bob/icon.png");
nameIcons.put("another name", "last/location/icon.png");

SharedPreferences keyValues = getContext().getSharedPreferences("name_icons_list", Context.MODE_PRIVATE);
SharedPreferences.Editor keyValuesEditor = keyValues.edit();

for (String s : nameIcons.keySet()) {
    // use the name as the key, and the icon as the value
    keyValuesEditor.putString(s, nameIcons.get(s));
}
keyValuesEditor.commit()

You would do something similar to read the key-value pairs again. Let me know if this works.

Update: If you're using API level 11 or later, there is a method to write out a String Set

So, is that a behavior to expect, a bug

Truth be told I am not sure. It looks like parser is interpreting count not as a column name but a function and expects following parentheses. Looks like a bug or at least a serious limitation of the parser.

is there a canonical way to go around?

Some options have been already mentioned by Herman and mattinbits so here more SQLish approach from me:

import org.apache.spark.sql.functions.count

df.groupBy("x").agg(count("*").alias("cnt")).where($"cnt"  > 2)

I just had the same problem. It is not a network permission but rather thread issue. Below code helped me to solve it. Put is in main activity

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    if (android.os.Build.VERSION.SDK_INT > 9)
    {
        StrictMode.ThreadPolicy policy = new 
        StrictMode.ThreadPolicy.Builder().permitAll().build();
        StrictMode.setThreadPolicy(policy);
    }

Go to iOS folder in your project and install pod -

$ pod install

If you are getting any error in installation of pod type command-

$ xcode-select -p

Result should be - /Applications/Xcode.app/Contents/Developer

If the path is incorrect then open your iOS project in Xcode and go to: Xcode->preferences->command line tools-> select Xcode

And again install the pod your issue will be fixed.

Use this method:

$_product = wc_get_product( $id );

Official API-docs: wc_get_product

You can access the parent ScaffoldState using Scaffold.of(context)

Then do something like

Scaffold.of(context).showSnackBar(SnackBar(
      content: Text("Sending Message"),
    ));

Snackbars are the official "Toast" from material design. See https://material.io/design/components/snackbars.html#usage

Here is a fully working example:

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: const Home(),
    );
  }
}

class Home extends StatelessWidget {
  const Home({
    Key key,
  }) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Snack bar'),
      ),

      /// We use [Builder] here to use a [context] that is a descendant of [Scaffold]
      /// or else [Scaffold.of] will return null
      body: Builder(
        builder: (context) => Center(
              child: RaisedButton(
                child: const Text('Show toast'),
                onPressed: () => _showToast(context),
              ),
            ),
      ),
    );
  }

  void _showToast(BuildContext context) {
    final scaffold = Scaffold.of(context);
    scaffold.showSnackBar(
      SnackBar(
        content: const Text('Added to favorite'),
        action: SnackBarAction(
            label: 'UNDO', onPressed: scaffold.hideCurrentSnackBar),
      ),
    );
  }
}

you can use localStorage for storing the json data:

the example is given below:-

let JSONDatas = [
    {"id": "Open"},
    {"id": "OpenNew", "label": "Open New"},
    {"id": "ZoomIn", "label": "Zoom In"},
    {"id": "ZoomOut", "label": "Zoom Out"},
    {"id": "Find", "label": "Find..."},
    {"id": "FindAgain", "label": "Find Again"},
    {"id": "Copy"},
    {"id": "CopyAgain", "label": "Copy Again"},
    {"id": "CopySVG", "label": "Copy SVG"},
    {"id": "ViewSVG", "label": "View SVG"}
]

localStorage.setItem("datas", JSON.stringify(JSONDatas));

let data = JSON.parse(localStorage.getItem("datas"));

console.log(data);

You can use the break keyword.

I have written a small routine which copies formula from a cell to clipboard which one can easily paste in Visual Basic Editor.

    Public Sub CopyExcelFormulaInVBAFormat()
        Dim strFormula As String
        Dim objDataObj As Object

        '\Check that single cell is selected!
       If Selection.Cells.Count > 1 Then
            MsgBox "Select single cell only!", vbCritical
            Exit Sub
        End If

        'Check if we are not on a blank cell!
       If Len(ActiveCell.Formula) = 0 Then
            MsgBox "No Formula To Copy!", vbCritical
            Exit Sub
        End If

        'Add quotes as required in VBE
       strFormula = Chr(34) & Replace(ActiveCell.Formula, Chr(34), Chr(34) & Chr(34)) & Chr(34)

        'This is ClsID of MSFORMS Data Object
       Set objDataObj = CreateObject("New:{1C3B4210-F441-11CE-B9EA-00AA006B1A69}")
        objDataObj.SetText strFormula, 1
        objDataObj.PutInClipboard
        MsgBox "VBA Format formula copied to Clipboard!", vbInformation

        Set objDataObj = Nothing

    End Sub

Faster clearing than Arrays.fill is with this (From Fast Serialization Lib). I just use arrayCopy (is native) to clear the array:

static Object[] EmptyObjArray = new Object[10000];

public static void clear(Object[] arr) {
    final int arrlen = arr.length;
    clear(arr, arrlen);
}

public static void clear(Object[] arr, int arrlen) {
    int count = 0;
    final int length = EmptyObjArray.length;
    while( arrlen - count > length) {
        System.arraycopy(EmptyObjArray,0,arr,count, length);
        count += length;
    }
    System.arraycopy(EmptyObjArray,0,arr,count, arrlen -count);
}

@SuppressWarnings({ "deprecation", "unchecked" })
public void swipeTopToBottom(AppiumDriver<MobileElement> driver) 
                    throws InterruptedException {
       Dimension dimensions = driver.manage().window().getSize();
        Double screenHeightStart = dimensions.getHeight() * 0.30;
        int scrollStart = screenHeightStart.intValue();
        System.out.println("s="+scrollStart);
        Double screenHeightEnd = dimensions.getHeight()*0.90;
        int scrollEnd = screenHeightEnd.intValue();
        driver.swipe(0,scrollStart,0,scrollEnd,2000);
        CommonUtils.threadWait(driver, 3000);
    }

This error is caused by:

Y = Dataset.iloc[:,18].values

Indexing is out of bounds here most probably because there are less than 19 columns in your Dataset, so column 18 does not exist. The following code you provided doesn't use Y at all, so you can just comment out this line for now.

PHP parser will search your entire code for <?php (or <? if short_open_tag = On), so HTML comment tags have no effect on PHP parser behavior & if you don't want to parse your PHP code, you have to use PHP commenting directives(/* */ or //).

You can turn on syntax highlighting based on the contents of the file.

For example, my Makefiles regardless of their extension the first line as follows:

#-*-Makefile-*- vim:syntax=make

This is typical practice for other editors such as vim.

However, for this to work you need to modify the Makefile.tmLanguage file.

1. Find the file (for Sublime Text 3 in Ubuntu) at:

   /opt/sublime_text/Packages/Makefile.sublime-package
   

Note, that is really a zip file. Copy it, rename with .zip at the end, and extract the Makefile.tmLanguage file from it.

2. Edit the new Makefile.tmLanguage by adding the "firstLineMatch" key and string after the "fileTypes" section. In the example below, the last two lines are new (should be added by you). The <string> section holds the regular expression, that will enable syntax highlighting for the files that match the first line. This expression recognizes two patterns: "-*-Makefile-*-" and "vim:syntax=make".

   ...
   <key>fileTypes</key>
   <array>
       <string>GNUmakefile</string>
       <string>makefile</string>
       <string>Makefile</string>
       <string>OCamlMakefile</string>
       <string>make</string>
   </array>
   
   <key>firstLineMatch</key>
   <string>^#\s*-\*-Makefile-\*-|^#.*\s*vim:syntax=make</string>
   

3. Place the modified Makefile.tmLanguage in the User settings directory:

   ~/.config/sublime-text-3/Packages/User/Makefile.tmLanguage
   

All the files matching the first line rule should turn the syntax highlighting on when opened.

In Linux, run file on the Eclipse executable, like this:

$ file /usr/bin/eclipse
eclipse: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.4.0, not stripped

Use Google Search Operators to find it for you

search google with the below code..

inurl:domain.com filetype:xml click on this to view sitemap search example

change domain.com to the domain you want to find the sitemap. this should list all the xml files listed for the given domain.. including all sitemaps :)

// @HostListener('scroll', ['$event']) // for scroll events of the current element
@HostListener('window:scroll', ['$event']) // for window scroll events
onScroll(event) {
  ...
}

or

<div (scroll)="onScroll($event)"></div>

1. Primitive type variable like string,number are always pass as pass by value.

2. Array and Object is passed as pass by reference or pass by value based on these two condition.

   • if you are changing value of that Object or array with new Object or Array then it is pass by Value.

     object1 = {item: "car"}; array1=[1,2,3];

   here you are assigning new object or array to old one.you are not changing the value of property of old object.so it is pass by value.

   • if you are changing a property value of an object or array then it is pass by Reference.

     object1.item= "car"; array1[0]=9;

   here you are changing a property value of old object.you are not assigning new object or array to old one.so it is pass by reference.

Code

    function passVar(object1, object2, number1) {

        object1.key1= "laptop";
        object2 = {
            key2: "computer"
        };
        number1 = number1 + 1;
    }

    var object1 = {
        key1: "car"
    };
    var object2 = {
        key2: "bike"
    };
    var number1 = 10;

    passVar(object1, object2, number1);
    console.log(object1.key1);
    console.log(object2.key2);
    console.log(number1);

Output: -
    laptop
    bike
    10

\ is an escape character in Python. \t gets interpreted as a tab. If you need \ character in a string, you have to use \\.

Your code should be:
test_file=open('c:\\Python27\\test.txt','r')

This is why I wrote Picky: http://picky.readthedocs.io/

It's a python package that tracks packages installed with either pip or conda in either virtualenvs and conda envs.

Yes you can, using SQLite you can read from or write to a database from within the jar file, so that you won't have to extract and then re jar it, follow my post http://shoaibinamdar.in/blog/?p=313

using the syntax "jdbc:sqlite::resource:" you would be able to read and write to a database from within the jar file

Don't think of it as exclusive. Use the IDE for the benefits it provides, and switch to vim/preferred text editor when you need some serious focus.

I find the IDE better for refactoring and browsing and debugging and for figuring out what to do. Small things are then done right in the IDE, large things I flip to vim to finish the job.

to_date() returns a date at 00:00:00, so you need to "remove" the minutes from the date you are comparing to:

select * 
from table
where trunc(es_date) = TO_DATE('27-APR-12','dd-MON-yy')

You probably want to create an index on trunc(es_date) if that is something you are doing on a regular basis.

The literal '27-APR-12' can fail very easily if the default date format is changed to anything different. So make sure you you always use to_date() with a proper format mask (or an ANSI literal: date '2012-04-27')

Although you did right in using to_date() and not relying on implict data type conversion, your usage of to_date() still has a subtle pitfall because of the format 'dd-MON-yy'.

With a different language setting this might easily fail e.g. TO_DATE('27-MAY-12','dd-MON-yy') when NLS_LANG is set to german. Avoid anything in the format that might be different in a different language. Using a four digit year and only numbers e.g. 'dd-mm-yyyy' or 'yyyy-mm-dd'

I was lazy and added the loops

import java.util.Arrays;


public class Sort {
    public static void main(String args[])
    {
        int [] array = new int[10];
        for ( int i = 0 ; i < array.length ; i++ ) {
            array[i] = ((int)(Math.random()*100+1));
        }
        Arrays.sort( array );
        for ( int i = 0 ; i < array.length ; i++ ) {
            System.out.println(array[i]);
        }
    }
}

Your array has a length of 10. You need one variable (i) which takes the values from 0to 9.

for ( int i = 0  ; i < array.length ;   i++ ) 
       ^               ^                   ^
       |               |                   ------  increment ( i = i + 1 )
       |               |
       |               +-------------------------- repeat as long i < 10
       +------------------------------------------ start value of i


Arrays.sort( array );

Is a library methods that sorts arrays.

You should add namespace if you are not using it:

System.Windows.Forms.MessageBox.Show("Some text", "Some title", 
    System.Windows.Forms.MessageBoxButtons.OK, 
    System.Windows.Forms.MessageBoxIcon.Error);

Alternatively, you can add at the begining of your file:

using System.Windows.Forms

and then use (as stated in previous answers):

MessageBox.Show("Some text", "Some title", 
    MessageBoxButtons.OK, MessageBoxIcon.Error);

Just want to add one more way. Found it elsewhere, and is quite simple. Say I want to pass yes for all the prompts at command line for a command "execute_command", Then I would simply pipe yes to it.

yes | execute_command

This will use yes as the answer to all yes/no prompts.

|| is the boolean OR operator. As in javascript, undefined, null, 0, false are considered as falsy values.

It simply means

true || true = true
false || true = true
true || false = true
false || false = false

undefined || "value" = "value"
"value" || undefined = "value"
null || "value" = "value"
"value" || null = "value"
0 || "value" = "value"
"value" || 0 = "value"
false || "value" = "value"
"value" || false = "value"

For anybody who will come upon this problem and they tried all that was suggested and nothing still works, this is how I sorted my problem, instead of doing LocalBroadcastManager.getInstance(this).registerReceiver(...) I first created a local variable of type LocalBroadcastManager,

private LocalBroadcastManager lbman;

And used this variable to carry out the registering and unregistering on the broadcastreceiver, that is

lbman.registerReceiver(bReceiver);

and

lbman.unregisterReceiver(bReceiver);

Have you tried this??

$("Textbox").rules("add", { regex: "^[a-zA-Z'.\\s]{1,40}$", messages: { regex: "The text is invalid..." } })

Note: make sure to escape all the "\" of ur regex by adding another "\" in front of them else the regex wont work as expected.

Please try this

    <input type="button" value="Home" class="homebutton" id="btnHome" onClick="Javascript:window.location.href = 'http://www.website.com/index.php';" />

window.location.href example:

 window.location.href = 'http://www.google.com'; //Will take you to Google.

window.open() example:

     window.open('http://www.google.com'); //This will open Google in a new window.

Just use Array#sample:

[:foo, :bar].sample # => :foo, or :bar :-)

It is available in Ruby 1.9.1+. To be also able to use it with an earlier version of Ruby, you could require "backports/1.9.1/array/sample".

Note that in Ruby 1.8.7 it exists under the unfortunate name choice; it was renamed in later version so you shouldn't use that.

Although not useful in this case, sample accepts a number argument in case you want a number of distinct samples.

1. int and int32 are one and the same (32-bit integer)
2. int16 is short int (2 bytes or 16-bits)
3. int64 is the long datatype (8 bytes or 64-bits)

Thanks to Mike's comment, I've re-read the doc and I've realised that my current user (i.e. userA that already has the create privilege) wasn't a direct/indirect member of the new owning role...

So the solution was quite simple - I've just done this grant:

grant userB to userA;

That's all folks ;-)

Another requirement is that the object has to be owned by user userA before altering it...

input() by default takes the input in form of strings.

if (0<= vote <=24):

vote takes a string input (suppose 4,5,etc) and becomes uncomparable.

The correct way is: vote = int(input("Enter your message")will convert the input to integer (4 to 4 or 5 to 5 depending on the input)

Solution:

Set the property RetainSameConnection on the Connection Manager to True so that temporary table created in one Control Flow task can be retained in another task.

Here is a sample SSIS package written in SSIS 2008 R2 that illustrates using temporary tables.

Walkthrough:

Create a stored procedure that will create a temporary table named ##tmpStateProvince and populate with few records. The sample SSIS package will first call the stored procedure and then will fetch the temporary table data to populate the records into another database table. The sample package will use the database named Sora Use the below create stored procedure script.

USE Sora;
GO

CREATE PROCEDURE dbo.PopulateTempTable
AS
BEGIN
    
    SET NOCOUNT ON;

    IF OBJECT_ID('TempDB..##tmpStateProvince') IS NOT NULL
        DROP TABLE ##tmpStateProvince;

    CREATE TABLE ##tmpStateProvince
    (
            CountryCode     nvarchar(3)         NOT NULL
        ,   StateCode       nvarchar(3)         NOT NULL
        ,   Name            nvarchar(30)        NOT NULL
    );

    INSERT INTO ##tmpStateProvince 
        (CountryCode, StateCode, Name)
    VALUES
        ('CA', 'AB', 'Alberta'),
        ('US', 'CA', 'California'),
        ('DE', 'HH', 'Hamburg'),
        ('FR', '86', 'Vienne'),
        ('AU', 'SA', 'South Australia'),
        ('VI', 'VI', 'Virgin Islands');
END
GO

Create a table named dbo.StateProvince that will be used as the destination table to populate the records from temporary table. Use the below create table script to create the destination table.

USE Sora;
GO

CREATE TABLE dbo.StateProvince
(
        StateProvinceID int IDENTITY(1,1)   NOT NULL
    ,   CountryCode     nvarchar(3)         NOT NULL
    ,   StateCode       nvarchar(3)         NOT NULL
    ,   Name            nvarchar(30)        NOT NULL
    CONSTRAINT [PK_StateProvinceID] PRIMARY KEY CLUSTERED
        ([StateProvinceID] ASC)
) ON [PRIMARY];
GO

Create an SSIS package using Business Intelligence Development Studio (BIDS). Right-click on the Connection Managers tab at the bottom of the package and click New OLE DB Connection... to create a new connection to access SQL Server 2008 R2 database.

Click New... on Configure OLE DB Connection Manager.

Perform the following actions on the Connection Manager dialog.

• Select Native OLE DB\SQL Server Native Client 10.0 from Provider since the package will connect to SQL Server 2008 R2 database
• Enter the Server name, like MACHINENAME\INSTANCE
• Select Use Windows Authentication from Log on to the server section or whichever you prefer.
• Select the database from Select or enter a database name, the sample uses the database name Sora.
• Click Test Connection
• Click OK on the Test connection succeeded message.
• Click OK on Connection Manager

The newly created data connection will appear on Configure OLE DB Connection Manager. Click OK.

OLE DB connection manager KIWI\SQLSERVER2008R2.Sora will appear under the Connection Manager tab at the bottom of the package. Right-click the connection manager and click Properties

Set the property RetainSameConnection on the connection KIWI\SQLSERVER2008R2.Sora to the value True.

Right-click anywhere inside the package and then click Variables to view the variables pane. Create the following variables.

• A new variable named PopulateTempTable of data type String in the package scope SO_5631010 and set the variable with the value EXEC dbo.PopulateTempTable.

• A new variable named FetchTempData of data type String in the package scope SO_5631010 and set the variable with the value SELECT CountryCode, StateCode, Name FROM ##tmpStateProvince

Drag and drop an Execute SQL Task on to the Control Flow tab. Double-click the Execute SQL Task to view the Execute SQL Task Editor.

On the General page of the Execute SQL Task Editor, perform the following actions.

• Set the Name to Create and populate temp table
• Set the Connection Type to OLE DB
• Set the Connection to KIWI\SQLSERVER2008R2.Sora
• Select Variable from SQLSourceType
• Select User::PopulateTempTable from SourceVariable
• Click OK

Drag and drop a Data Flow Task onto the Control Flow tab. Rename the Data Flow Task as Transfer temp data to database table. Connect the green arrow from the Execute SQL Task to the Data Flow Task.

Double-click the Data Flow Task to switch to Data Flow tab. Drag and drop an OLE DB Source onto the Data Flow tab. Double-click OLE DB Source to view the OLE DB Source Editor.

On the Connection Manager page of the OLE DB Source Editor, perform the following actions.

• Select KIWI\SQLSERVER2008R2.Sora from OLE DB Connection Manager
• Select SQL command from variable from Data access mode
• Select User::FetchTempData from Variable name
• Click Columns page

Clicking Columns page on OLE DB Source Editor will display the following error because the table ##tmpStateProvince specified in the source command variable does not exist and SSIS is unable to read the column definition.

To fix the error, execute the statement EXEC dbo.PopulateTempTable using SQL Server Management Studio (SSMS) on the database Sora so that the stored procedure will create the temporary table. After executing the stored procedure, click Columns page on OLE DB Source Editor, you will see the column information. Click OK.

Drag and drop OLE DB Destination onto the Data Flow tab. Connect the green arrow from OLE DB Source to OLE DB Destination. Double-click OLE DB Destination to open OLE DB Destination Editor.

On the Connection Manager page of the OLE DB Destination Editor, perform the following actions.

• Select KIWI\SQLSERVER2008R2.Sora from OLE DB Connection Manager
• Select Table or view - fast load from Data access mode
• Select [dbo].[StateProvince] from Name of the table or the view
• Click Mappings page

Click Mappings page on the OLE DB Destination Editor would automatically map the columns if the input and output column names are same. Click OK. Column StateProvinceID does not have a matching input column and it is defined as an IDENTITY column in database. Hence, no mapping is required.

Data Flow tab should look something like this after configuring all the components.

Click the OLE DB Source on Data Flow tab and press F4 to view Properties. Set the property ValidateExternalMetadata to False so that SSIS would not try to check for the existence of the temporary table during validation phase of the package execution.

Execute the query select * from dbo.StateProvince in the SQL Server Management Studio (SSMS) to find the number of rows in the table. It should be empty before executing the package.

Execute the package. Control Flow shows successful execution.

In Data Flow tab, you will notice that the package successfully processed 6 rows. The stored procedure created early in this posted inserted 6 rows into the temporary table.

Execute the query select * from dbo.StateProvince in the SQL Server Management Studio (SSMS) to find the 6 rows successfully inserted into the table. The data should match with rows founds in the stored procedure.

The above example illustrated how to create and use temporary table within a package.

A better and more organized way of overriding Devise controllers and views using namespaces:

Create the following folders:

app/controllers/my_devise
app/views/my_devise

Put all controllers that you want to override into app/controllers/my_devise and add MyDevise namespace to controller class names. Registrations example:

# app/controllers/my_devise/registrations_controller.rb
class MyDevise::RegistrationsController < Devise::RegistrationsController

  ...

  def create
    # add custom create logic here
  end

  ...    

end 

Change your routes accordingly:

devise_for :users,
           :controllers  => {
             :registrations => 'my_devise/registrations',
             # ...
           }

Copy all required views into app/views/my_devise from Devise gem folder or use rails generate devise:views, delete the views you are not overriding and rename devise folder to my_devise.

This way you will have everything neatly organized in two folders.

Like this:

if ($('input[value=""]').length > 0) {
   console.log('some fields are empty!')
}

Pure-PHP implementation of Rijndael exists with phpseclib available as composer package and works on PHP 7.3 (tested by me).

There's a page on the phpseclib docs, which generates sample code after you input the basic variables (cipher, mode, key size, bit size). It outputs the following for Rijndael, ECB, 256, 256:

$decoded = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, ENCRYPT_KEY, $term, MCRYPT_MODE_ECB);

works like this with the library

$rijndael = new \phpseclib\Crypt\Rijndael(\phpseclib\Crypt\Rijndael::MODE_ECB);
$rijndael->setKey(ENCRYPT_KEY);
$rijndael->setKeyLength(256);
$rijndael->disablePadding();
$rijndael->setBlockLength(256);

$decoded = $rijndael->decrypt($term);

* $term was base64_decoded

You have several options. All these methods work on Linux as well as on Windows or Mac OS X. However, be aware that most PDFs do not include to full, complete fontface when they have a font embedded. Mostly they include just the subset of glyphs used in the document.

Using pdftops

One of the most frequently used methods to do this on *nix systems consists of the following steps:

1. Convert the PDF to PostScript, for example by using XPDF's pdftops (on Windows: pdftops.exe helper program.
2. Now fonts will be embedded in .pfa (PostScript) format + you can extract them using a text editor.
3. You may need to convert the .pfa (ASCII) to a .pfb (binary) file using the t1utils and pfa2pfb.
4. In PDFs there are never .pfm or .afm files (font metric files) embedded (because PDF viewer have internal knowledge about these). Without these, font files are hardly usable in a visually pleasing way.

Using fontforge

Another method is to use the Free font editor FontForge:

1. Use the "Open Font" dialogbox used when opening files.
2. Then select "Extract from PDF" in the filter section of dialog.
3. Select the PDF file with the font to be extracted.
4. A "Pick a font" dialogbox opens -- select here which font to open.

Check the FontForge manual. You may need to follow a few specific steps which are not necessarily straightforward in order to save the extracted font data as a file which is re-usable.

Using mupdf

Next, MuPDF. This application comes with a utility called pdfextract (on Windows: pdfextract.exe) which can extract fonts and images from PDFs. (In case you don't know about MuPDF, which still is relatively unknown and new: "MuPDF is a Free lightweight PDF viewer and toolkit written in portable C.", written by Artifex Software developers, the same company that gave us Ghostscript.)
_{(Update: Newer versions of MuPDF have moved the former functionality of 'pdfextract' to the command 'mutool extract'. Download it here: mupdf.com/downloads)}

Note: pdfextract.exe is a command-line program. To use it, do the following:

c:\>  pdfextract.exe  c:\path\to\filename.pdf         # (on Windows)
$>    pdfextract  /path/tofilename.pdf                # (on Linux, Unix, Mac OS X)

This command will dump all of the extractable files from the pdf file referenced into the current directory. Generally you will see a variety of files: images as well as fonts. These include PNG, TTF, CFF, CID, etc. The image names will be like img-0412.png if the PDF object number of the image was 412. The fontnames will be like FGETYK+LinLibertineI-0966.ttf, if the font's PDF object number was 966.

CFF (Compact Font Format) files are a recognized format that can be converted to other formats via a variety of converters for use on different operating systems.

Again: be aware that most of these font files may have only a subset of characters and may not represent the complete typeface.

Update: (Jul 2013) Recent versions of mupdf have seen an internal reshuffling and renaming of their binaries, not just once, but several times. The main utility used to be a 'swiss knife'-alike binary called mubusy (name inspired by busybox?), which more recently was renamed to mutool. These support the sub-commands info, clean, extract, poster and show. Unfortunatey, the official documentation for these tools isn't up to date (yet). If you're on a Mac using 'MacPorts': then the utility was renamed in order to avoid name clashes with other utilities using identical names, and you may need to use mupdfextract.

To achieve the (roughly) equivalent results with mutool as its previous tool pdfextract did, just run mubusy extract ....*

So to extract fonts and images, you may need to run one of the following commandlines:

c:\>  mutool.exe extract filename.pdf      # (on Windows)
$>    mutool     extract filename.pdf      # (on Linux, Unix, Mac OS X)

Downloads are here: mupdf.com/downloads

Using gs (Ghostscript)

Then, Ghostscript can also extract fonts directly from PDFs. However, it needs the help of a special utility program named extractFonts.ps, written in PostScript language, which is available from the Ghostscript source code repository.

Now use it, you need to run both, this file extractFonts.ps and your PDF file. Ghostscript will then use the instructions from the PostScript program to extract the fonts from the PDF. It looks like this on Windows (yes, Ghostscript understands the 'forward slash', /, as a path separator also on Windows!):

gswin32c.exe                  ^
  -q -dNODISPLAY              ^
   c:/path/to/extractFonts.ps ^
  -c "(c:/path/to/your/PDFFile.pdf) extractFonts quit"

or on Linux, Unix or Mac OS X:

gs                          \
  -q -dNODISPLAY            \
   /path/to/extractFonts.ps \
  -c "(/path/to/your/PDFFile.pdf) extractFonts quit"

I've tested the Ghostscript method a few years ago. At the time it did extract *.ttf (TrueType) just fine. I don't know if other font types will also be extracted at all, and if so, in a re-usable way. I don't know if the utility does block extracting of fonts which are marked as protected.

Using pdf-parser.py

Finally, Didier Stevens' pdf-parser.py: this one is probably not as easy to use, because you need to have some know-how about internal PDF structures. pdf-parser.py is a Python script which can do a lot of other things too. It can also decompress and extract arbitrary streams from objects, and therefore it can extract embedded font files too.

But you need to know what to look for. Let's see it with an example. I have a file named big.pdf. As a first step I use the -s parameter to search the PDF for any occurrence of the keyword FontFile (pdf-parser.py does not require a case sensitive search):

pdf-parser.py -s fontfile big.pdf

In my case, for my big1.pdf, I get this result:

obj 9 0
 Type: /FontDescriptor
 Referencing: 15 0 R
  <<   
    /Ascent 728
    /CapHeight 716
    /Descent -210 
    /Flags 32
    /FontBBox [ -665 -325 2000 1006 ]
    /FontFile2 15 0 R
    /FontName /ArialMT
    /ItalicAngle 0
    /StemV 87
    /Type /FontDescriptor
    /XHeight 519
  >>   

obj 11 0 
 Type: /FontDescriptor
 Referencing: 16 0 R
  <<   
    /Ascent 728
    /CapHeight 716
    /Descent -210 
    /Flags 262176
    /FontBBox [ -628 -376 2000 1018 ]
    /FontFile2 16 0 R
    /FontName /Arial-BoldMT
    /ItalicAngle 0
    /StemV 165
    /Type /FontDescriptor
    /XHeight 519
  >>   

It tells me that there are two instances of FontFile2 inside the PDF, and these are in PDF objects no. 15 and no. 16, respectively. Object no. 15 holds the /FontFile2 for font /ArialMT, object no. 16 holds the /FontFile2 for font /Arial-BoldMT.

To show this more clearly:

pdf-parser.py -s fontfile big1.pdf | grep -i fontfile
  /FontFile2 15 0 R
  /FontFile2 16 0 R

A quick peeking into the PDF specification reveals the the keyword /FontFile2 relates to a 'stream containing a TrueType font program' (/FontFile would relate to a 'stream containing a Type 1 font program' and /FontFile3 would relate to a 'stream containing a font program whose format is specified by the Subtype entry in the stream dictionary' {hence being either a Type1C or a CIDFontType0C subtype}.)

To look specifically at PDF object no. 15 (which holds the font /ArialMT), one can use the -o 15 parameter:

pdf-parser.py -o 15 big1.pdf

 obj 15 0
  Type: 
  Referencing: 
  Contains stream
   <<
     /Length1 778552
     /Length 1581435
     /Filter /ASCIIHexDecode
   >>

This pdf-parser.py output tells us that this object contains a stream (which it will not directly display) that has a length of 1.581.435 Bytes and is encoded ( == "compressed") with ASCIIHexEncode and needs to be decoded ( == "de-compressed" or "filtered") with the help of the standard /ASCIIHexDecode filter.

To dump any stream from an object, pdf-parser.py can be called with the -d dumpname parameter. Let's do it:

pdf-parser.py -o 15 -d dumped-data.ext big1.pdf

Our extracted data dump will be in the file named dumped-data.ext. Let's see how big it is:

ls -l dumped-data.ext
  -rw-r--r--  1 kurtpfeifle  staff  1581435 Apr 11 00:29 dumped-data.ext

Oh look, it is 1.581.435 Bytes. We saw this figure in the previous command's output. Opening this file with a text editor confirms that its content is ASCII hex encoded data.

Opening the file with a font reading tool like otfinfo (this is a part of the lcdf-typetools package) will lead to some disappointment at first:

otfinfo -i dumped-data.ext
  otfinfo: dumped-data.ext: not an OpenType font (bad magic number)

OK, this is because we did not (yet) let pdf-parser.py make use of its full magic: to dump a filtered, decoded stream. For this we have to add the -f parameter:

pdf-parser.py -o 15 -f -d dumped-data-decoded.ext big1.pdf

What's the size is this new file?

ls -l dumped-data-decoded.ext
  -rw-r--r--  1 kurtpfeifle  staff  778552 Apr 11 00:39 dumped-data-decoded.ext

Oh, look: that exact number was also already stored in the PDF object no. 15 dictionary as the value for key /Length1...

What does file think it is?

file dumped-data-decoded.ext
  dumped-data-decoded.ext: TrueType font data

What does otfinfo tell us about it?

otfinfo -i dumped-data-decoded.ext
  Family:              Arial
  Subfamily:           Regular
  Full name:           Arial
  PostScript name:     ArialMT

So Bingo!, we have a winner: pdf-parser.py did indeed extract a valid font file for us. Given the size of this file (778.552 Bytes), it looks like this font had been embedded even completely in the PDF...

We could rename it to arial-regular.ttf and install it as such and happily make use of it.

Caveats:

• In any case you need to follow the license that applies to the font. Some font licences do not allow free use and/or distribution. Pirating fonts is like pirating any software or other copyrighted material.

• Most PDFs which are in the wild out there do not embed the full font anyway, but only subsets. Extracting a subset of a font is only useful in a very limited scope, if at all.

Please do also read the following about Pros and (more) Cons regarding font extraction efforts:

You can also do this at the beginning of the query:

SET ARITHABORT OFF 
SET ANSI_WARNINGS OFF

So if you have something like 100/0 it will return NULL. I've only done this for simple queries, so I don't know how it will affect longer/complex ones.

I was looking for something similar and I decided to make my own version where you can also specify a different seed if wanted (list of characters) as parameter:

CREATE FUNCTION `random_string`(length SMALLINT(3), seed VARCHAR(255)) RETURNS varchar(255) CHARSET utf8
    NO SQL
BEGIN
    SET @output = '';

    IF seed IS NULL OR seed = '' THEN SET seed = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789'; END IF;

    SET @rnd_multiplier = LENGTH(seed);

    WHILE LENGTH(@output) < length DO
        # Select random character and add to output
        SET @output = CONCAT(@output, SUBSTRING(seed, RAND() * (@rnd_multiplier + 1), 1));
    END WHILE;

    RETURN @output;
END

Can be used as:

SELECT random_string(10, '')

Which would use the built-in seed of upper- and lowercase characters + digits. NULL would also be value instead of ''.

But one could specify a custom seed while calling:

SELECT random_string(10, '1234')

Another possible option would be to use Datejs

Then you can do

Date.getDaysInMonth(2009, 9)     

Although adding a library just for this function is overkill, it's always nice to know all the options you have available to you :)

If You have jar file then create bat file with:

java -jar NameOfJar.jar

Use this query:

DELETE FROM tableName;

Note: To delete some specific record you can give the condition in where clause in the query also.

OR you can use this query also:

truncate tableName;

Also remember that you should not have any relationship with other table. If there will be any foreign key constraint in the table then those record will not be deleted and will give the error.

The syntax you wrote as first is not valid. You can achieve something using the follow:

var map =  {"aaa": "rrr", "bbb": "ppp" /* etc */ };

The return value of os.system is OS-dependant.

On Unix, the return value is a 16-bit number that contains two different pieces of information. From the documentation:

a 16-bit number, whose low byte is the signal number that killed the process, and whose high byte is the exit status (if the signal number is zero)

So if the signal number (low byte) is 0, it would, in theory, be safe to shift the result by 8 bits (result >> 8) to get the error code. The function os.WEXITSTATUS does exactly this. If the error code is 0, that usually means that the process exited without errors.

On Windows, the documentation specifies that the return value of os.system is shell-dependant. If the shell is cmd.exe (the default one), the value is the return code of the process. Again, 0 would mean that there weren't errors.

For others error codes:

• on Linux
• on Windows

With a running instance of myExecutableName having a PID 15073:

hitting Tab twice after $ gdb myExecu in the command line, will automagically autocompletes to:

$ gdb myExecutableName 15073

and will attach gdb to this process. That's nice!

For example :

<div style="height:100px; width:100px; background:#000000"></div>

here.

you give css to div of height and width having 100px and background as black.

PS : try to avoid inline-css you can make external CSS and import in your html file.

you can refer here for CSS

hope this helps.

So for example if you are trying to change the text of the anchor on the current page that you are on only using CSS, then here is a simple solution.

I want to change the anchor text colour on my software page to light blue:

<div class="navbar">
    <ul>
       <a href="../index.html"><li>Home</li></a>
       <a href="usefulsites.html"><li>Useful Sites</li></a>
       <a href="software.html"><li class="currentpage">Software</li></a>
       <a href="workbench.html"><li>The Workbench</li></a>
       <a href="contact.php"><li>Contact</a></li></a>
    </ul>
</div>

And before anyone says that I got the <li> tags and the <a> tags mixed up, this is what makes it work as you are applying the value to the text itself only when you are on that page. Unfortunately, if you are using PHP to input header tags, then this will not work for obvious reasons. Then I put this in my style.css, with all my pages using the same style sheet:

.currentpage {
        color: lightblue;
}

Or use this in the JS file after your fancybox is set up:

$('#link_id').trigger('click');

I believe Fancybox 1.2.1 will use default options otherwise from my testing when I needed to do this.

EDIT: as of Java8 you'd better use Files class:

Path resultingPath = Files.createDirectories('A/B');

I don't know if this ultimately fixes your problem but class File has method mkdirs() which fully creates the path specified by the file.

File f = new File("/A/B/");
f.mkdirs();

How long does the batch process take to write the file? It may be easiest to let it go ahead and then compare the file against a copy of the file from the previous run to see if they are identical.

Use extract(datetime) function it's so easy, simple.

It returns year, month, day, minute, second

Example:

select extract(year from sysdate) from dual;

Spring works in standalone application. You are using the wrong way to create a spring bean. The correct way to do it like this:

@Component
public class Main {

    public static void main(String[] args) {
        ApplicationContext context = 
            new ClassPathXmlApplicationContext("META-INF/config.xml");

        Main p = context.getBean(Main.class);
        p.start(args);
    }

    @Autowired
    private MyBean myBean;
    private void start(String[] args) {
        System.out.println("my beans method: " + myBean.getStr());
    }
}

@Service 
public class MyBean {
    public String getStr() {
        return "string";
    }
}

In the first case (the one in the question), you are creating the object by yourself, rather than getting it from the Spring context. So Spring does not get a chance to Autowire the dependencies (which causes the NullPointerException).

In the second case (the one in this answer), you get the bean from the Spring context and hence it is Spring managed and Spring takes care of autowiring.

Redis. Let’s say you’ve written a site in php; for whatever reason, it becomes popular and it’s ahead of its time or has porno on it. You realize this php is so freaking slow, "I’m gonna lose my fans because they simply won’t wait 10 seconds for a page." You have a sudden realization that a web page has a constant url (it never changes, whoa), a primary key if you will, and then you recall that memory is fast while disk is slow and php is even slower. :( Then you fashion a storage mechanism using memory and this URL that you call a "key" while the webpage content you decide to call the "value." That’s all you have - key and content. You call it "meme cache." You like Richard Dawkins because he's awesome. You cache your html like squirrels cache their nuts. You don’t need to rewrite your crap php code. You are happy. Then you see that others have done it -- but you choose Redis because the other one has confusing images of cats, some with fangs.

Mongo. You’ve written a site. Heck you’ve written many, and in any language. You realize that much of your time is spent writing those stinking SQL clauses. You’re not a dba, yet there you are, writing stupid sql statements... not just one but freaking everywhere. "select this, select that". But in particular you remember the irritating WHERE clause. Where lastname equals "thornton" and movie equals "bad santa." Urgh. You think, "why don’t those dbas just do their job and give me some stored procedures?" Then you forget some minor field like middlename and then you have to drop the table, export all 10G of big data and create another with this new field, and import the data -- and that goes on 10 times during the next 14 days as you keep on remembering crap like salutation, title, plus adding a foreign key with addresses. Then you figure that lastname should be lastName. Almost one change a day. Then you say darnit. I have to get on and write a web site/system, never mind this data model bs. So you google, "I hate writing SQL, please no SQL, make it stop" but up pops 'nosql' and then you read some stuff and it says it just dumps data without any schema. You remember last week's fiasco dropping more tables and smile. Then you choose mongo because some big guys like 'airbud' the apt rental site uses it. Sweet. No more data model changes because you have a model you just keep on changing.

You can set a data-* attribute on an elm using attr(), and then select using that attribute:

var elm = $('a').attr('data-test',123); //assign 123 using attr()
elm = $("a[data-test=123]"); //select elm using attribute

and now for that elm, both attr() and data() will yield 123:

console.log(elm.attr('data-test')); //123
console.log(elm.data('test')); //123

However, if you modify the value to be 456 using attr(), data() will still be 123:

elm.attr('data-test',456); //modify to 456
elm = $("a[data-test=456]"); //reselect elm using new 456 attribute

console.log(elm.attr('data-test')); //456
console.log(elm.data('test')); //123

So as I understand it, seems like you probably should steer clear of intermingling attr() and data() commands in your code if you don't have to. Because attr() seems to correspond directly with the DOM whereas data() interacts with the 'memory', though its initial value can be from the DOM. But the key point is that the two are not necessarily in sync at all.

So just be careful.

At any rate, if you aren't changing the data-* attribute in the DOM or in the memory, then you won't have a problem. Soon as you start modifying values is when potential problems can arise.

Thanks to @Clarence Liu to @Ash's answer, as well as this post.

@Andrew has answered it clearly here. But as simple as this also works even if the directory is not empty:

git init .
git remote add origin <repository-url>
git pull origin master

A faster and shorter notation for null checks can be:

value == null ? "UNDEFINED" : value

This line is equivalent to:

if(value == null) {
       console.log("UNDEFINED")
} else {
    console.log(value)
}

Especially when you have a lot of null check it is a nice short notation.

Its advantages are that it simplifies the usage of WebSockets as you described in #2, and probably more importantly it provides fail-overs to other protocols in the event that WebSockets are not supported on the browser or server. I would avoid using WebSockets directly unless you are very familiar with what environments they don't work and you are capable of working around those limitations.

This is a good read on both WebSockets and Socket.IO.

No you can't use bind variables that way. In your second example :into_bind in v_query_str is just a placeholder for value of variable v_num_of_employees. Your select into statement will turn into something like:

SELECT COUNT(*) INTO  FROM emp_...

because the value of v_num_of_employees is null at EXECUTE IMMEDIATE.

Your first example presents the correct way to bind the return value to a variable.

Edit

The original poster has edited the second code block that I'm referring in my answer to use OUT parameter mode for v_num_of_employees instead of the default IN mode. This modification makes the both examples functionally equivalent.
