You can do so in Firefox and Safari (Chrome also?)

::selection { background: transparent; }
::-moz-selection { background: transparent; }

Absolutely position divs over the text area with a z-index higher and give these divs a transparent GIF background graphic.

Note after a bit more thought - You'd need to have these 'covers' be linked so clicking on them would take you to where the tab was supposed to, which means you could/should do this with the anchor element set to display:box, width and height set as well as the transparent background image.

<div 
 style="-moz-user-select: none; -webkit-user-select: none; -ms-user-select:none; user-select:none;-o-user-select:none;" 
 unselectable="on"
 onselectstart="return false;" 
 onmousedown="return false;">
    Blabla
</div>

Getting the text the user has selected is relatively simple. There's no benefit to be gained by involving jQuery since you need nothing other than the window and document objects.

function getSelectionText() {
    var text = "";
    if (window.getSelection) {
        text = window.getSelection().toString();
    } else if (document.selection && document.selection.type != "Control") {
        text = document.selection.createRange().text;
    }
    return text;
}

If you're interested in an implementation that will also deal with selections in <textarea> and texty <input> elements, you could use the following. Since it's now 2016 I'm omitting the code required for IE <= 8 support but I've posted stuff for that in many places on SO.

function getSelectionText() {_x000D_
    var text = "";_x000D_
    var activeEl = document.activeElement;_x000D_
    var activeElTagName = activeEl ? activeEl.tagName.toLowerCase() : null;_x000D_
    if (_x000D_
      (activeElTagName == "textarea") || (activeElTagName == "input" &&_x000D_
      /^(?:text|search|password|tel|url)$/i.test(activeEl.type)) &&_x000D_
      (typeof activeEl.selectionStart == "number")_x000D_
    ) {_x000D_
        text = activeEl.value.slice(activeEl.selectionStart, activeEl.selectionEnd);_x000D_
    } else if (window.getSelection) {_x000D_
        text = window.getSelection().toString();_x000D_
    }_x000D_
    return text;_x000D_
}_x000D_
_x000D_
document.onmouseup = document.onkeyup = document.onselectionchange = function() {_x000D_
  document.getElementById("sel").value = getSelectionText();_x000D_
};

Selection:_x000D_
<br>_x000D_
<textarea id="sel" rows="3" cols="50"></textarea>_x000D_
<p>Please select some text.</p>_x000D_
<input value="Some text in a text input">_x000D_
<br>_x000D_
<input type="search" value="Some text in a search input">_x000D_
<br>_x000D_
<input type="tel" value="4872349749823">_x000D_
<br>_x000D_
<textarea>Some text in a textarea</textarea>

I altered the jQuery plugin posted above so it would work on live elements.

(function ($) {
$.fn.disableSelection = function () {
    return this.each(function () {
        if (typeof this.onselectstart != 'undefined') {
            this.onselectstart = function() { return false; };
        } else if (typeof this.style.MozUserSelect != 'undefined') {
            this.style.MozUserSelect = 'none';
        } else {
            this.onmousedown = function() { return false; };
        }
    });
};
})(jQuery);

Then you could so something like:

$(document).ready(function() {
    $('label').disableSelection();

    // Or to make everything unselectable
    $('*').disableSelection();
});

I would create a comparator for the person class that can be parametrized with a certain sorting behaviour. Here I can set the sorting order but it can be modified to allow sorting for other person attributes as well.

public class PersonComparator implements Comparator<Person> {

  public enum SortOrder {ASCENDING, DESCENDING}

  private SortOrder sortOrder;

  public PersonComparator(SortOrder sortOrder) {
    this.sortOrder = sortOrder;
  }

  @Override
  public int compare(Person person1, Person person2) {
    Integer age1 = person1.getAge();
    Integer age2 = person2.getAge();
    int compare = Math.signum(age1.compareTo(age2));

    if (sortOrder == ASCENDING) {
      return compare;
    } else {
      return compare * (-1);
    }
  }
}

(hope it compiles now, I have no IDE or JDK at hand, coded 'blind')

Edit

Thanks to Thomas, edited the code. I wouldn't say that the usage of Math.signum is good, performant, effective, but I'd like to keep it as a reminder, that the compareTo method can return any integer and multiplying by (-1) will fail if the implementation returns Integer.MIN_INTEGER... And I removed the setter because it's cheap enough to construct a new PersonComparator just when it's needed.

But I keep the boxing because it shows that I rely on an existing Comparable implementation. Could have done something like Comparable<Integer> age1 = new Integer(person1.getAge()); but that looked too ugly. The idea was to show a pattern which could easily be adapted to other Person attributes, like name, birthday as Date and so on.

Right click your project, go to New > Other > Android > Android Icon Set

Then follow the instructions on the Wizard

Change your code to.

<?php
$sqlupdate1 = "UPDATE table SET commodity_quantity=".$qty."WHERE user=".$rows['user'];
?>

There was syntax error in your query.

I also found a tool called TCP/IP Test Server [Edit: no longer available from the original developer, but still available via Brothersoft] which seems to do what I need too. But I didn't try it because it is not listed on big freeware-sites (like CNET...) and no source code is published so that it won't reassure a paranoid sysadmin.

You don't need any javascript, you just need your href to be coded like this:

<a href="mailto:[email protected]">email me here!</a>

In html page for pc is easy to implement

<embed src="study/sample.pdf" type="application/pdf"   height="300px" width="100%">

but pdf show in mobile by this code is not possible you must need a plugin

if you have not responsive your site. Then above code pdf not show in mobile but you can put download option after the code

<embed src="study/sample.pdf" type="application/pdf"   height="300px" width="100%" class="responsive">
<a href="study/sample.pdf">download</a>

Make sure that Spring version and xsd version both are same.In my case I am using Spring 4.1.1 so my all xsd should be version *-4.1.xsd

Use jQuery's

$(this).addClass('showhideExtra_up_hover');

and

$(this).addClass('showhideExtra_down_hover');

You will have to make a call to the YouTube data API's video resource after you make the search call. You can put up to 50 video IDs in a search, so you won't have to call it for each element.

https://developers.google.com/youtube/v3/docs/videos/list

You'll want to set part=contentDetails, because the duration is there.

For example, the following call:

https://www.googleapis.com/youtube/v3/videos?id=9bZkp7q19f0&part=contentDetails&key={YOUR_API_KEY}

Gives this result:

{
 "kind": "youtube#videoListResponse",
 "etag": "\"XlbeM5oNbUofJuiuGi6IkumnZR8/ny1S4th-ku477VARrY_U4tIqcTw\"",
 "items": [
  {

   "id": "9bZkp7q19f0",
   "kind": "youtube#video",
   "etag": "\"XlbeM5oNbUofJuiuGi6IkumnZR8/HN8ILnw-DBXyCcTsc7JG0z51BGg\"",
   "contentDetails": {
    "duration": "PT4M13S",
    "dimension": "2d",
    "definition": "hd",
    "caption": "false",
    "licensedContent": true,
    "regionRestriction": {
     "blocked": [
      "DE"
     ]
    }
   }
  }
 ]
}

The time is formatted as an ISO 8601 string. PT stands for Time Duration, 4M is 4 minutes, and 13S is 13 seconds.

Best solution:

function startsWith(str, word) {
    return str.lastIndexOf(word, 0) === 0;
}

And here is endsWith if you need that too:

function endsWith(str, word) {
    return str.indexOf(word, str.length - word.length) !== -1;
}

For those that prefer to prototype it into String:

String.prototype.startsWith || (String.prototype.startsWith = function(word) {
    return this.lastIndexOf(word, 0) === 0;
});

String.prototype.endsWith   || (String.prototype.endsWith = function(word) {
    return this.indexOf(word, this.length - word.length) !== -1;
});

Usage:

"abc".startsWith("ab")
true
"c".ensdWith("c") 
true

With method:

startsWith("aaa", "a")
true
startsWith("aaa", "ab")
false
startsWith("abc", "abc")
true
startsWith("abc", "c")
false
startsWith("abc", "a")
true
startsWith("abc", "ba")
false
startsWith("abc", "ab")
true

If you use the command

time /T

that will print the time. (without the /T, it will try to set the time)

date /T

is similar for the date.

If cmd's Command Extensions are enabled (they are enabled by default, but in this question they appear to be disabled), then the environment variables %DATE% and %TIME% will expand to the current date and time each time they are expanded. The format used is the same as the DATE and TIME commands.

To see the other dynamic environment variables that exist when Command Extensions are enabled, run set /?.

First, use SoapUI to create your soap project from the wsdl. Try to send a request to play with the wsdl's operations. Observe how the xml request composes your data fields.

And then, if you are having problem getting SoapClient acts as you want, here is how I debug it. Set the option trace so that the function __getLastRequest() is available for use.

$soapClient = new SoapClient('http://yourwdsdlurl.com?wsdl', ['trace' => true]);
$params = ['user' => 'Hey', 'account' => '12345'];
$response = $soapClient->__soapCall('<operation>', $params);
$xml = $soapClient->__getLastRequest();

Then the $xml variable contains the xml that SoapClient compose for your request. Compare this xml with the one generated in the SoapUI.

For me, SoapClient seems to ignore the keys of the associative array $params and interpret it as indexed array, causing wrong parameter data in the xml. That is, if I reorder the data in $params, the $response is completely different:

$params = ['account' => '12345', 'user' => 'Hey'];
$response = $soapClient->__soapCall('<operation>', $params);

Kotlin

Extending the Throwable class will give you the String property error.stackTraceString:

val Throwable.stackTraceString: String
  get() {
    val sw = StringWriter()
    val pw = PrintWriter(sw)
    this.printStackTrace(pw)
    return sw.toString()
  }

To hide your status bar in iOS7:

Open Your plist-file, then add a add a row called "View controller-based status bar appearance" and set its value to NO.

From .Net 3.5 you can use LINQ extension method that (sometimes) makes code flow a bit better.

Usage looks like this:

using System.Linq; 

// ...

public void My()
{
    var myArray = new[] { "abc", "123", "zyx" };
    List<string> myList = myArray.ToList();
}

PS. There's also ToArray() method that works in other way.

void is a reserved JavaScript keyword. It evaluates the expression and always returns undefined.

Your code is working just fine, you have to declare javscript method before DOM ready.

You can also use below just simple to check:

If startDate <> Nothing Then
your logic
End If

It will check that the startDate variable of DateTime datatype is null or not.

Generating strings from (for example) lowercase characters:

import random, string

def randomword(length):
   letters = string.ascii_lowercase
   return ''.join(random.choice(letters) for i in range(length))

Results:

>>> randomword(10)
'vxnxikmhdc'
>>> randomword(10)
'ytqhdohksy'

I have come to this question and the one below several times.

how to call scalar function in sql server 2008

Each time, I try entering the Function using the syntax shown here in SQL Server Management Studio, or SSMS, to see the results, and each time I get the errors.

For me, that is because my result set is in tabular data format. Therefore, to see the results in SSMS, I have to call it like this:

SELECT * FROM dbo.Afisho_rankimin_TABLE(5);

I understand that the author's question involved a scalar function, so this answer is only to help others who come to StackOverflow often when they have a problem with a query (like me).

I hope this helps others.

Bootstrap 3

Using Bootstrap 3's grid system:

<div class="container">
  <div class="row">
    <div class="col-xs-4">Menu</div>
    <div class="col-xs-8">
      <div class="row">
        <div class="col-md-4 col-md-push-8">Right Content</div>
        <div class="col-md-8 col-md-pull-4">Content</div>
      </div>
    </div>
  </div>
</div>

Working example: http://bootply.com/93614

Explanation

First, we set two columns that will stay in place no matter the screen resolution (col-xs-*).

Next, we divide the larger, right hand column in to two columns that will collapse on top of each other on tablet sized devices and lower (col-md-*).

Finally, we shift the display order using the matching class (col-md-[push|pull]-*). You push the first column over by the amount of the second, and pull the second by the amount of the first.

This answer is for anyone encountering pdfs with images and needing to use OCR. I could not find a workable off-the-shelf solution; nothing that gave me the accuracy I needed.

Here are the steps I found to work.

1. Use pdfimages from https://poppler.freedesktop.org/ to turn the pages of the pdf into images.

2. Use Tesseract to detect rotation and ImageMagick mogrify to fix it.

3. Use OpenCV to find and extract tables.

4. Use OpenCV to find and extract each cell from the table.

5. Use OpenCV to crop and clean up each cell so that there is no noise that will confuse OCR software.

6. Use Tesseract to OCR each cell.

7. Combine the extracted text of each cell into the format you need.

I wrote a python package with modules that can help with those steps.

Repo: https://github.com/eihli/image-table-ocr

Docs & Source: https://eihli.github.io/image-table-ocr/pdf_table_extraction_and_ocr.html

Some of the steps don't require code, they take advantage of external tools like pdfimages and tesseract. I'll provide some brief examples for a couple of the steps that do require code.

2. Finding tables:

This link was a good reference while figuring out how to find tables. https://answers.opencv.org/question/63847/how-to-extract-tables-from-an-image/

import cv2

def find_tables(image):
    BLUR_KERNEL_SIZE = (17, 17)
    STD_DEV_X_DIRECTION = 0
    STD_DEV_Y_DIRECTION = 0
    blurred = cv2.GaussianBlur(image, BLUR_KERNEL_SIZE, STD_DEV_X_DIRECTION, STD_DEV_Y_DIRECTION)
    MAX_COLOR_VAL = 255
    BLOCK_SIZE = 15
    SUBTRACT_FROM_MEAN = -2

    img_bin = cv2.adaptiveThreshold(
        ~blurred,
        MAX_COLOR_VAL,
        cv2.ADAPTIVE_THRESH_MEAN_C,
        cv2.THRESH_BINARY,
        BLOCK_SIZE,
        SUBTRACT_FROM_MEAN,
    )
    vertical = horizontal = img_bin.copy()
    SCALE = 5
    image_width, image_height = horizontal.shape
    horizontal_kernel = cv2.getStructuringElement(cv2.MORPH_RECT, (int(image_width / SCALE), 1))
    horizontally_opened = cv2.morphologyEx(img_bin, cv2.MORPH_OPEN, horizontal_kernel)
    vertical_kernel = cv2.getStructuringElement(cv2.MORPH_RECT, (1, int(image_height / SCALE)))
    vertically_opened = cv2.morphologyEx(img_bin, cv2.MORPH_OPEN, vertical_kernel)

    horizontally_dilated = cv2.dilate(horizontally_opened, cv2.getStructuringElement(cv2.MORPH_RECT, (40, 1)))
    vertically_dilated = cv2.dilate(vertically_opened, cv2.getStructuringElement(cv2.MORPH_RECT, (1, 60)))

    mask = horizontally_dilated + vertically_dilated
    contours, hierarchy = cv2.findContours(
        mask, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE,
    )

    MIN_TABLE_AREA = 1e5
    contours = [c for c in contours if cv2.contourArea(c) > MIN_TABLE_AREA]
    perimeter_lengths = [cv2.arcLength(c, True) for c in contours]
    epsilons = [0.1 * p for p in perimeter_lengths]
    approx_polys = [cv2.approxPolyDP(c, e, True) for c, e in zip(contours, epsilons)]
    bounding_rects = [cv2.boundingRect(a) for a in approx_polys]

    # The link where a lot of this code was borrowed from recommends an
    # additional step to check the number of "joints" inside this bounding rectangle.
    # A table should have a lot of intersections. We might have a rectangular image
    # here though which would only have 4 intersections, 1 at each corner.
    # Leaving that step as a future TODO if it is ever necessary.
    images = [image[y:y+h, x:x+w] for x, y, w, h in bounding_rects]
    return images

3. Extract cells from table.

This is very similar to 2, so I won't include all the code. The part I will reference will be in sorting the cells.

We want to identify the cells from left-to-right, top-to-bottom.

We’ll find the rectangle with the most top-left corner. Then we’ll find all of the rectangles that have a center that is within the top-y and bottom-y values of that top-left rectangle. Then we’ll sort those rectangles by the x value of their center. We’ll remove those rectangles from the list and repeat.

def cell_in_same_row(c1, c2):
    c1_center = c1[1] + c1[3] - c1[3] / 2
    c2_bottom = c2[1] + c2[3]
    c2_top = c2[1]
    return c2_top < c1_center < c2_bottom

orig_cells = [c for c in cells]
rows = []
while cells:
    first = cells[0]
    rest = cells[1:]
    cells_in_same_row = sorted(
        [
            c for c in rest
            if cell_in_same_row(c, first)
        ],
        key=lambda c: c[0]
    )

    row_cells = sorted([first] + cells_in_same_row, key=lambda c: c[0])
    rows.append(row_cells)
    cells = [
        c for c in rest
        if not cell_in_same_row(c, first)
    ]

# Sort rows by average height of their center.
def avg_height_of_center(row):
    centers = [y + h - h / 2 for x, y, w, h in row]
    return sum(centers) / len(centers)

rows.sort(key=avg_height_of_center)

Based on your question, I believe the answer is how to trigger a blur, not just (or even) set the event:

 $('#textArea').trigger('blur');

See my answer to the question Importing modules from parent folder for related information, including why my answer doesn't use the unreliable __file__ variable. This simple solution should be cross-compatible with different operating systems as the modules os and inspect come as part of Python.

First, you need to import parts of the inspect and os modules.

from inspect import getsourcefile
from os.path import abspath

Next, use the following line anywhere else it's needed in your Python code:

abspath(getsourcefile(lambda:0))

How it works:

From the built-in module os (description below), the abspath tool is imported.

OS routines for Mac, NT, or Posix depending on what system we're on.

Then getsourcefile (description below) is imported from the built-in module inspect.

Get useful information from live Python objects.

• abspath(path) returns the absolute/full version of a file path
• getsourcefile(lambda:0) somehow gets the internal source file of the lambda function object, so returns '<pyshell#nn>' in the Python shell or returns the file path of the Python code currently being executed.

Using abspath on the result of getsourcefile(lambda:0) should make sure that the file path generated is the full file path of the Python file.
This explained solution was originally based on code from the answer at How do I get the path of the current executed file in Python?.

If you can't use the delay method as Robert Harvey suggested, you can use setTimeout.

Eg.

setTimeout(function() {$("#test").animate({"top":"-=80px"})} , 1500); // delays 1.5 sec
setTimeout(function() {$("#test").animate({"opacity":"0"})} , 1500 + 1000); // delays 1 sec after the previous one

Some of the tutorials I found that are easy to understand are:

• http://www.phpfreaks.com/tutorial/basic-pagination

It makes way more sense to break up your list into page-sized chunks, and only query your database one chunk at a time. This drastically reduces server processing time and page load time, as well as gives your user smaller pieces of info to digest, so he doesn't choke on whatever crap you're trying to feed him. The act of doing this is called pagination.

A basic pagination routine seems long and scary at first, but once you close your eyes, take a deep breath, and look at each piece of the script individually, you will find it's actually pretty easy stuff

The script:

// find out how many rows are in the table 
$sql = "SELECT COUNT(*) FROM numbers";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);
$r = mysql_fetch_row($result);
$numrows = $r[0];

// number of rows to show per page
$rowsperpage = 10;
// find out total pages
$totalpages = ceil($numrows / $rowsperpage);

// get the current page or set a default
if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) {
   // cast var as int
   $currentpage = (int) $_GET['currentpage'];
} else {
   // default page num
   $currentpage = 1;
} // end if

// if current page is greater than total pages...
if ($currentpage > $totalpages) {
   // set current page to last page
   $currentpage = $totalpages;
} // end if
// if current page is less than first page...
if ($currentpage < 1) {
   // set current page to first page
   $currentpage = 1;
} // end if

// the offset of the list, based on current page 
$offset = ($currentpage - 1) * $rowsperpage;

// get the info from the db 
$sql = "SELECT id, number FROM numbers LIMIT $offset, $rowsperpage";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);

// while there are rows to be fetched...
while ($list = mysql_fetch_assoc($result)) {
   // echo data
   echo $list['id'] . " : " . $list['number'] . "<br />";
} // end while

/******  build the pagination links ******/
// range of num links to show
$range = 3;

// if not on page 1, don't show back links
if ($currentpage > 1) {
   // show << link to go back to page 1
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=1'><<</a> ";
   // get previous page num
   $prevpage = $currentpage - 1;
   // show < link to go back to 1 page
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$prevpage'><</a> ";
} // end if 

// loop to show links to range of pages around current page
for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {
   // if it's a valid page number...
   if (($x > 0) && ($x <= $totalpages)) {
      // if we're on current page...
      if ($x == $currentpage) {
         // 'highlight' it but don't make a link
         echo " [<b>$x</b>] ";
      // if not current page...
      } else {
         // make it a link
         echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> ";
      } // end else
   } // end if 
} // end for

// if not on last page, show forward and last page links        
if ($currentpage != $totalpages) {
   // get next page
   $nextpage = $currentpage + 1;
    // echo forward link for next page 
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$nextpage'>></a> ";
   // echo forward link for lastpage
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$totalpages'>>></a> ";
} // end if
/****** end build pagination links ******/

This tutorial is intended for developers who wish to give their users the ability to step through a large number of database rows in manageable chunks instead of the whole lot in one go.

By searching for my userid in the registry, I found

Just wait some time before closing the window!

if (navigator.appName != 'Microsoft Internet Explorer') {
    newWin.close();
} else {
    window.setTimeout(function() {newWin.close()}, 3000);
}

Deletion of a topic has been supported since 0.8.2.x version. You have to enable topic deletion (setting delete.topic.enable to true) on all brokers first.

Note: Ever since 1.0.x, the functionality being stable, delete.topic.enable is by default true.

Follow this step by step process for manual deletion of topics

1. Stop Kafka server
2. Delete the topic directory, on each broker (as defined in the logs.dirs and log.dir properties) with rm -rf command
3. Connect to Zookeeper instance: zookeeper-shell.sh host:port
4. From within the Zookeeper instance:
   1. List the topics using: ls /brokers/topics
   2. Remove the topic folder from ZooKeeper using: rmr /brokers/topics/yourtopic
   3. Exit the Zookeeper instance (Ctrl+C)
5. Restart Kafka server
6. Confirm if it was deleted or not by using this command kafka-topics.sh --list --zookeeper host:port

One liner and IE11 friendly:

> (window.location.href).match('c=([^&]*)')[1]
> "m2-m3-m4-m5"

You need to account for DateTime Kind too.

public static DateTime GetTime(this DateTime d)

If your looking how to copy an Amazon AWS .pem keypair into a different region do the following:

openssl rsa -in .ssh/amazon-aws.pem -pubout > .ssh/amazon-aws.pub

Then

aws ec2 import-key-pair --key-name amazon-aws --public-key-material '$(cat .ssh/amazon-aws.pub)' --region us-west-2

I would prefer to use the strlen function as library functions are implemented in the best way.

So, I would write if(strlen(p)==0) //Empty string

const monthNames = ["Jan", "Feb", "Mar", "Apr", "May", "Jun",
 "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"
];
export function getFormattedDateAndTime(startDate) {
    if (startDate != null) {
      var launchDate = new Date(startDate);
       var day = launchDate.getUTCDate();
      var month = monthNames[launchDate.getMonth()];
      var year = launchDate.getFullYear(); 
      var min = launchDate.getMinutes();
      var hour = launchDate.getHours();
      var time = launchDate.toLocaleString('en-US', { hour: 'numeric', minute: 'numeric', hour12: true });

      return  day + " " + month + " " + year + " - " + time + ""  ;
    }
    return "";
   }

If you want to set cookie and get it outside of request, Laravel is not your friend.

Laravel cookies are part of Request, so if you want to do this outside of Request object, use good 'ole PHP setcookie(..) and $_COOKIE to get it.

Query 3.0 version

Breaking change: .load(), .unload(), and .error() removed

These methods are shortcuts for event operations, but had several API limitations. The event .load() method conflicted with the ajax .load() method. The .error() method could not be used with window.onerror because of the way the DOM method is defined. If you need to attach events by these names, use the .on() method, e.g. change $("img").load(fn) to $(img).on("load", fn).¹

$(window).load(function() {});

Should be changed to

$(window).on('load', function (e) {})

These are all equivalent:

$(function(){
}); 

jQuery(document).ready(function(){
});

$(document).ready(function(){
});

$(document).on('ready', function(){
})

"not equal" So in this case, $RESULT is tested to not be equal to zero.

However, the test is done numerically, not alphabetically:

n1 -ne n2     True if the integers n1 and n2 are not algebraically equal.

compared to:

s1 != s2      True if the strings s1 and s2 are not identical.

A cookie is basically just an item in a dictionary. Each item has a key and a value. For authentication, the key could be something like 'username' and the value would be the username. Each time you make a request to a website, your browser will include the cookies in the request, and the host server will check the cookies. So authentication can be done automatically like that.

To set a cookie, you just have to add it to the response the server sends back after requests. The browser will then add the cookie upon receiving the response.

There are different options you can configure for the cookie server side, like expiration times or encryption. An encrypted cookie is often referred to as a signed cookie. Basically the server encrypts the key and value in the dictionary item, so only the server can make use of the information. So then cookie would be secure.

A browser will save the cookies set by the server. In the HTTP header of every request the browser makes to that server, it will add the cookies. It will only add cookies for the domains that set them. Example.com can set a cookie and also add options in the HTTP header for the browsers to send the cookie back to subdomains, like sub.example.com. It would be unacceptable for a browser to ever sends cookies to a different domain.

Simply get date and convert

Declare @Date as Date =Getdate()

Select Format(@Date,'dd/MM/yyyy') as [dd/MM/yyyy] // output: 22/10/2020
Select Format(@Date,'dd-MM-yyyy') as [dd-MM-yyyy] // output: 22-10-2020

//string date
Select Format(cast('25/jun/2013' as date),'dd/MM/yyyy') as StringtoDate // output: 25/06/2013

Put static resources under the directory:

/src/main/resources/static

add this property in application.properties file

server.servlet.context-path=/pdx

You can access from http://localhost:8080/pdx/images/image.jpg

You can code as a lambda expression as the third parameter(on complete) to the subscribe method. Here I re-set the departmentModel variable to the default values.

saveData(data:DepartmentModel){
  return this.ds.sendDepartmentOnSubmit(data).
  subscribe(response=>this.status=response,
   ()=>{},
   ()=>this.departmentModel={DepartmentId:0});
}

I know this post is old but...

I was able to do this, my problem was that I forgot to make my property static.

public static class MyStaticClass
{
    private static NonStaticObject _myObject = new NonStaticObject();

    //property
    public static NonStaticObject MyObject
    {
        get { return _myObject; }
        set { _myObject = value; }
    }
}

Based on the previous answers, here is another solution which returns the same result as df2.teams.apply(pd.Series) with a much faster run time:

pd.DataFrame([{x: y for x, y in enumerate(item)} for item in df2['teams'].values.tolist()], index=df2.index)

Timings:

In [1]:
import pandas as pd
d1 = {'teams': [['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG'],
                ['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG'],['SF', 'NYG']]}
df2 = pd.DataFrame(d1)
df2 = pd.concat([df2]*1000).reset_index(drop=True)

In [2]: %timeit df2['teams'].apply(pd.Series)

8.27 s ± 2.73 s per loop (mean ± std. dev. of 7 runs, 1 loop each)

In [3]: %timeit pd.DataFrame([{x: y for x, y in enumerate(item)} for item in df2['teams'].values.tolist()], index=df2.index)

35.4 ms ± 5.22 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

If you need a simple working solution, try using DefaultTableModel.

If you have created your own table model, that extends AbstractTableModel, then you should also implement removeRow() method. The exact implementation depends on the underlying structure, that you have used to store data.

For example, if you have used Vector, then it may be something like this:

public class SimpleTableModel extends AbstractTableModel {
    private Vector<String> columnNames = new Vector<String>();
    // Each value in the vector is a row; String[] - row data;
    private Vector<String[]> data = new Vector<String[]>();

    ...

    public String getValueAt(int row, int col) {
        return data.get(row)[col];
    }

    ...

    public void removeRow(int row) {
        data.removeElementAt(row);
    }
}

If you have used List, then it would be very much alike:

// Each item in the list is a row; String[] - row data;
List<String[]> arr = new ArrayList<String[]>();

public void removeRow(int row) {
    data.remove(row);
}

HashMap:

//Integer - row number; String[] - row data;
HashMap<Integer, String[]> data = new HashMap<Integer, String[]>();

public void removeRow(Integer row) {
    data.remove(row);
}

And if you are using arrays like this one

String[][] data = { { "a", "b" }, { "c", "d" } };

then you're out of luck, because there is no way to dynamically remove elements from arrays. You may try to use arrays by storing separately some flags notifying which rows are deleted and which are not, or by some other devious way, but I would advise against it... That would introduce unnecessary complexity, and would in fact just be solving a problem by creating another. That's a sure-fire way to end up here. Try one of the above ways to store your table data instead.

For better understanding of how this works, and what to do to make your own model work properly, I strongly advise you to refer to Java Tutorial, DefaultTableModel API and it's source code.

In general I added the private Object _ temporarily to the object. You have to open the privacy exlipcitly in the "Power-constructor" for the method. If you call the method from the prototype, you will be able to overwrite the prototype-method

• Make a public method accessible in the "Power-constructor": (ctx is the object context)

  ctx.test = GD.Fabric.open('test', GD.Test.prototype, ctx, _); // is a private object
  

• Now I have this openPrivacy:

  GD.Fabric.openPrivacy = function(func, clss, ctx, _) {
      return function() {
          ctx._ = _;
          var res = clss[func].apply(ctx, arguments);
          ctx._ = null;
          return res;
      };
  };
  

To be able to build with C# 6 syntax use this in path:

C:\Program Files (x86)\MSBuild\14.0\Bin

Only works in IE

 $(function(){

        var xml = '<?xml version="1.0"?><foo><bar>bar</bar></foo>'; 

        var xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
        xmlDoc.async="false";
        xmlDoc.loadXML(xml);

        alert(xmlDoc.xml);

    });

Then push xmlDoc.xml to your java code.

I too had this error, on Windows Server 2008 IIS 7, I had no visual studio installed so a reinstall / repair of .NET 4.0 did the trick.

Use the below code to find the count of number of matches that the regex finds in your input

        Pattern p = Pattern.compile(regex, Pattern.MULTILINE | Pattern.DOTALL);// "regex" here indicates your predefined regex.
        Matcher m = p.matcher(pattern); // "pattern" indicates your string to match the pattern against with
        boolean b = m.matches();
        if(b)
        count++;
        while (m.find())
        count++;

This is a generalized code not specific one though, tailor it to suit your need

Please feel free to correct me if there is any mistake.

My syntax error was semi-hidden in an f-string

 print(f'num_flex_rows = {self.}\nFlex Rows = {flex_rows}\nMax elements = {max_elements}')

should be

 print(f'num_flex_rows = {self.num_rows}\nFlex Rows = {flex_rows}\nMax elements = {max_elements}')

It didn't have the PyCharm spell-check-red line under the error.

It did give me a clue, yet when I searched on this error message, it of course did not find the error in that bit of code above.

Had I looked more closely at the error message, I would have found the '' in the error. Seeing Line 1 was discouraging and thus wasn't paying close attention :-( Searching for

self.)

yielded nothing. Searching for

self.

yielded practically everything :-\

If I can help you avoid even a minute longer of deskchecking your code, then mission accomplished :-)

If you worked the correct way to create your migrations by using the command Add-Migration "Name_Of_Migration" then you can do the following to get a clean start (reset, with loss of data, of course):

1. Update-database -TargetMigration:0

   Normally your DB is empty now since the down methods were executed.

2. Update-database

   This will recreate your DB to your current migration

continue simply skips the rest of the code in the loop until next iteration

Just Clear the table body.

F5 is a standard shortcut to run a macro in VBA editor. I don't think you can add a shortcut key in editor itself. If you want to run the macro from excel, you can assign a shortcut from there.

In excel press alt+F8 to open macro dialog box. select the macro for which you want to assign shortcut key and click options. there you can assign a shortcut to the macro.

There is an option “unlimited scrollback buffer” which you can find under Preferences > Profiles > Terminal or you can just pump up number of lines that you want to have in history in the same place.

I would use this:

private static Random random = new Random();

public Object getRandomFromEnum(Class<? extends Enum<?>> clazz) {
    return clazz.values()[random.nextInt(clazz.values().length)];
}

As jzd says, you can use System.currentTimeMillis. If you need it in a Date object but don't want to create a new Date object, you can use Date.setTime to reuse an existing Date object. Personally I hate the fact that Date is mutable, but maybe it's useful to you in this particular case. Similarly, Calendar has a setTimeInMillis method.

If possible though, it would probably be better just to keep it as a long. If you only need a timestamp, effectively, then that would be the best approach.

I'm using the following, though it's hardcoded for gnome-terminal. It also changes the CWD and buffer for vim to be the same as your current buffer and it's directory.

:silent execute '!gnome-terminal -- zsh -i -c "cd ' shellescape(expand("%:h")) '; vim' shellescape(expand("%:p")) '; zsh -i"' <cr>

This one will calculate a HashCode for each object, optimized for string, number and virtually anything that has a getHashCode function. For the rest it assigns a new reference number.

(function() {
  var __gRefID = 0;
  window.getHashCode = function(ref)
  {
      if (ref == null) { throw Error("Unable to calculate HashCode on a null reference"); }

      // already cached reference id
      if (ref.hasOwnProperty("__refID")) { return ref["__refID"]; }

      // numbers are already hashcodes
      if (typeof ref === "number") { return ref; }

      // strings are immutable, so we need to calculate this every time
      if (typeof ref === "string")
      {
          var hash = 0, i, chr;
          for (i = 0; i < ref.length; i++) {
            chr = ref.charCodeAt(i);
            hash = ((hash << 5) - hash) + chr;
            hash |= 0;
          }
          return hash;
      }

      // virtual call
      if (typeof ref.getHashCode === "function") { return ref.getHashCode(); }

      // generate and return a new reference id
      return (ref["__refID"] = "ref" + __gRefID++);
  }
})();

You can read the binary from stdout instead of saving the png to the sdcard and then pulling it:

adb shell screencap -p | sed 's|\r$||' > screenshot.png

This should save a little time, but not much.

Have you tried to use Tomcat's Manager application? It allows you to undeploy / deploy war files with out shutting Tomcat down.

If you don't want to use the Manager application, you can also delete the war file from the webapps directory, Tomcat will undeploy the application after a short period of time. You can then copy a war file back into the directory, and Tomcat will deploy the war file.

If you are running Tomcat on Windows, you may need to configure your Context to not lock various files.

If you absolutely can't have any downtime, you may want to look at Tomcat 7's Parallel deployments You may deploy multiple versions of a web application with the same context path at the same time. The rules used to match requests to a context version are as follows:

• If no session information is present in the request, use the latest version.
• If session information is present in the request, check the session manager of each version for a matching session and if one is found, use that version.
• If session information is present in the request but no matching session can be found, use the latest version.

a='\nu + \lambda + \theta'
d=a.encode('string_escape').replace('\\\\','\\')
print(d)
# \nu + \lambda + \theta

This shows that there is a single backslash before the n, l and t:

print(list(d))
# ['\\', 'n', 'u', ' ', '+', ' ', '\\', 'l', 'a', 'm', 'b', 'd', 'a', ' ', '+', ' ', '\\', 't', 'h', 'e', 't', 'a']

There is something funky going on with your GUI. Here is a simple example of grabbing some user input through a Tkinter.Entry. Notice that the text retrieved only has a single backslash before the n, l, and t. Thus no extra processing should be necessary:

import Tkinter as tk

def callback():
    print(list(text.get()))

root = tk.Tk()
root.config()

b = tk.Button(root, text="get", width=10, command=callback)

text=tk.StringVar()

entry = tk.Entry(root,textvariable=text)
b.pack(padx=5, pady=5)
entry.pack(padx=5, pady=5)
root.mainloop()

If you type \nu + \lambda + \theta into the Entry box, the console will (correctly) print:

['\\', 'n', 'u', ' ', '+', ' ', '\\', 'l', 'a', 'm', 'b', 'd', 'a', ' ', '+', ' ', '\\', 't', 'h', 'e', 't', 'a']

If your GUI is not returning similar results (as your post seems to suggest), then I'd recommend looking into fixing the GUI problem, rather than mucking around with string_escape and string replace.

They are found on either one of the below locations depending on how chrome was installed

• When chrome is installed at the user level, it's located at:

~/Users/<username>/Library/Application\ Support/Google/Chrome/Default/Extensions

• When installed at the root level, it's at:

/Library/Application\ Support/Google/Chrome/Default/Extensions

One more thing that might be the problem in a case similar to described - X is not forwarded and $DISPLAY is not set when 'xauth' program is not installed on the remote side. You can see it searches for it when you run "ssh -Xv ip_address", and, if not found, fails, which's not seen unless you turn on verbose mode (a fail IMO). You can usually find 'xauth' in a package with the same name.

Use .text(…) when you intend to display the value as a simple text.

Use .html(…) when you intend to display the value as a html formatted text (or HTML content).

You should definitely use .text(...) when you’re not sure that your text (e.g. coming from an input control) do not contain characters/tags that has special meaning in HTML. This is really important because this could result in the text will not display properly but it could also cause that an unwanted JS script snippet (e.g. coming from another user input) to be activated.

use this actiion

$(document).ready(function () {
var a = this.id;

alert (a);
});

Got this error also....

it occurs when save to filepath contains invalid characters, in my case:

path = "C:/somefolder/anotherfolder\file.xls";

Note the existence of both \ and /

*Also may occur if trying to save to directory which doesn't already exist.

You could just specify the following property -Dhttps.protocols=TLSv1.1,TLSv1.2 at your server which configures the JVM to specify which TLS protocol version should be used during all https connections from client.

Try below code:

MessageBox.Show("Test Information Message", "Caption", MessageBoxButtons.OK, MessageBoxIcon.Information);

curl -sS https://getcomposer.org/installer | sudo php
sudo mv composer.phar /usr/local/bin/composer
export PATH="$HOME/.composer/vendor/bin:$PATH"

If you have installed by this way simply

Delete composer.phar from where you've putted it.

In this case path will be /usr/local/bin/composer

Note: There is no need to delete the exported path.

Default user for MySQL is "root", and server "localhost".

For example, say you were creating a web application to list and display recipes. You might want your customers to be able to sort the list, display features of the recipes, and so on before they choose the recipe to open. In order to do this, you need to associate things like cooking time, primary ingredient, meal position, and so on right inside the list elements for the recipes.

<li><a href="recipe1.html">Borscht</a></li>
<li><a href="recipe2.html">Chocolate Mousse</a></li>
<li><a href="recipe3.html">Almond Radiccio Salad</a></li>
<li><a href="recipe4.html">Deviled Eggs</a></li>

In order to get that information into the page, you could do many different things. You could add comments to each LI element, you could add rel attributes to the list items, you could place all the recipes in separate folders based on time, meal, and ingredient (i.e. ). The solution that most developers took was to use class attributes to store information about the current element. This has several advantages:

• You can store multiple classes on an element
• The class names can be human readable
• It’s easy to access classes with JavaScript (className)
• The class is associated with the element it’s on

But there are some major drawbacks to this method:

• You have to remember what the classes do. If you forget or a new developer takes over the project, the classes might be removed or changed without realizing that that affects how the application runs.
• Classes are also used for styling with CSS, and you might duplicate CSS classes with data classes by mistake, ending up with strange styles on your live pages.
• It’s more difficult to add on multiple data elements. If you have multiple data elements, you need to access them in some way with your JavaScript, either by the name of the class or the position in the class list. But it’s easy to mess up.

All the other methods I suggested had these problems as well as others. But since it was the only way to quickly and easily include data, that’s what we did. HTML5 Data Attributes to the Rescue

HTML5 added a new type of attribute to any element—the custom data element (data-*). These are custom (denoted by the *) attributes that you can add to your HTML elements to define any type of data you want. They consist of two parts:

Attribute Name This is the name of the attribute. It must be at least one lowercase character and have the prefix data-. For example: data-main-ingredient, data-cooking-time, data-meal. This is the name of your data.

Attribute Vaule Like any other HTML attribute, you include the data itself in quotes separated by an equal sign. This data can be any string that is valid on a web page. For example: data-main-ingredient="chocolate".

You can then apply these data attributes to any HTML element you want. For example, you could define the information in the example list above:

<li data-main-ingredient="beets" data-cooking-time="1 hour" data-meal="dinner"><a href="recipe1.html">Borscht</a></li>
<li data-main-ingredient="chocolate" data-cooking-time="30 minutes" data-meal="dessert"><a href="recipe2.html">Chocolate Mousse</a></li>
<li data-main-ingredient="radiccio" data-cooking-time="20 minutes" data-meal="dinner"><a href="recipe1.html">Almond Radiccio Salad</a></li>
<li data-main-ingredient="eggs" data-cooking-time="15 minutes" data-meal="appetizer"><a href="recipe1.html">Deviled Eggs</a></li>

Once you have that information in your HTML, you will be able to access it with JavaScript and manipulate the page based on that data.

If you want only the line number do this:

grep -n Pattern file.ext | gawk '{print $1}' FS=":"

Example:

$ grep -n 9780545460262 EXT20130410.txt | gawk '{print $1}' FS=":" 
48793
52285
54023

the pattern maybe looks like this :

substr(STRING, ( length(STRING) - (TOTAL_GET_LENGTH - 1) ),TOTAL_GET_LENGTH)

in your case , it will like this :

substr('299123456789', (length('299123456789')-(9 - 1)),9)

substr('299123456789', (12-8),9)

substr('299123456789', 4,9)

the result ? of course '123456789'

the length is dynamic , voila :)

$(":button").click(function () {                
                $("#anchor_google")[0].click();
            });

1. First, find the button by type(using ":") if id is not given.
2. Second,find the anchor tag by id or in some other tag like div and $("#anchor_google")[0] returns the DOM object.

box-shadow: -15px 0px 17px -7px rgba(0,0,0,0.75);

The first px value is the "Horizontal Length" set to -15px to position the shadow towards the left, the next px value is set to 0 so the shadow top and bottom is centred to minimise the top and bottom shadow.

The third value(17px) is known as the blur radius. The higher the number, the more blurred the shadow will be. And then last px value -7px is The spread radius, a positive value increases the size of the shadow, a negative value decreases the size of the shadow, at -7px it keeps the shadow from appearing above and below the item.

I have a better way:

http
    .authorizeRequests()
    .antMatchers("/api/v1/signup/**").permitAll()
    .anyRequest().authenticated()

angular.module('myApp').controller('myCtrl', function($scope, $rootScope) {
   var a = //something in the scope
   //put it in the root scope
    $rootScope.test = "TEST";
 });

angular.module('myApp').controller('myCtrl2', function($scope, $rootScope) {
   var b = //get var a from root scope somehow
   //use var b

   $scope.value = $rootScope.test;
   alert($scope.value);

 //    var b = $rootScope.test;
 //  alert(b);
 });

I hope this complete example will help you.

This is the TaxiInfo class which holds information about a taxi ride:

namespace Taxi.Models
{
    public class TaxiInfo
    {
        public String Driver { get; set; }
        public Double Fare { get; set; }
        public Double Distance { get; set; }
        public String StartLocation { get; set; }
        public String EndLocation { get; set; }
    }
}

We also have a convenience model which holds a List of TaxiInfo(s):

namespace Taxi.Models
{
    public class TaxiInfoSet
    {
        public List<TaxiInfo> TaxiInfoList { get; set; }

        public TaxiInfoSet(params TaxiInfo[] TaxiInfos)
        {
            TaxiInfoList = new List<TaxiInfo>();

            foreach(var TaxiInfo in TaxiInfos)
            {
                TaxiInfoList.Add(TaxiInfo);
            }
        }
    }
}

Now in the home controller we have the default Index action which for this example makes two taxi drivers and adds them to the list contained in a TaxiInfo:

public ActionResult Index()
{
    var taxi1 = new TaxiInfo() { Fare = 20.2, Distance = 15, Driver = "Billy", StartLocation = "Perth", EndLocation = "Brisbane" };
    var taxi2 = new TaxiInfo() { Fare = 2339.2, Distance = 1500, Driver = "Smith", StartLocation = "Perth", EndLocation = "America" };

    return View(new TaxiInfoSet(taxi1,taxi2));
}

The code for the view is as follows:

@model Taxi.Models.TaxiInfoSet
@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

@foreach(var TaxiInfo in Model.TaxiInfoList){
    <form>
        <h1>Cost: [email protected]</h1>
        <h2>Distance: @(TaxiInfo.Distance) km</h2>
        <p>
            Our diver, @TaxiInfo.Driver will take you from @TaxiInfo.StartLocation to @TaxiInfo.EndLocation
        </p>
        @Html.ActionLink("Home","Booking",TaxiInfo)
    </form>
}

The ActionLink is responsible for the re-directing to the booking action of the Home controller (and passing in the appropriate TaxiInfo object) which is defiend as follows:

    public ActionResult Booking(TaxiInfo Taxi)
    {
        return View(Taxi);
    }

This returns a the following view:

@model Taxi.Models.TaxiInfo

@{
    ViewBag.Title = "Booking";
}

<h2>Booking For</h2>
<h1>@Model.Driver, going from @Model.StartLocation to @Model.EndLocation (a total of @Model.Distance km) for [email protected]</h1>

Throwing my $0.02 in here since none of the answers worked, but did send me on the right path. What happened was that a previous foreign constraint was throwing the error. Obvious when you think about it.

So in your new migration's up method, first drop that original constraint, rename the column, then add the constraint again with the new column name. In the down method, you do the exact opposite so that it's back to the sold setting.

/**
 * Run the migrations.
 *
 * @return void
 */
public function up()
{
    Schema::table('proxy4s', function (Blueprint $table) {
        // Drop it
        $table->dropForeign(['server_id']);

        // Rename
        $table->renameColumn('server_id', 'linux_server_id');

        // Add it
        $table->foreign('linux_server_id')->references('id')->on('linux_servers');
    });
}

/**
 * Reverse the migrations.
 *
 * @return void
 */
public function down()
{
    Schema::table('proxy4s', function (Blueprint $table) {
        // Drop it
        $table->dropForeign(['linux_server_id']);

        // Rename
        $table->renameColumn('linux_server_id', 'server_id');

        // Add it
        $table->foreign('server_id')->references('id')->on('linux_servers');
    });
}

Hope this saves someone some time in the future!

char c = 'a';
String a = Integer.toHexString(c); // gives you---> a = "61"

<div style="specify your dimension:overflow:hidden">
    <div style="margin-top:-50px">

    </div>
</div>

The above will crop 50px from the top of the image. You may want to compute to come up wit a top margin that will fit your requirements based on the dimension of the image.

To crop from the bottom simply specify the height of the outer div and remove the inner div. Apply the same principle to crop from the sides.

Kafka stores all the information in zookeeper. You can see all the topic related information under brokers->topics. If you wish to get all the topics programmatically you can do that using Zookeeper API.

It is explained in detail in below links Tutorialspoint, Zookeeper Programmer guide

The examples to os.walk in the documentation show how to do this:

for root, dirs, filenames in os.walk(indir):
    for f in filenames:
        log = open(os.path.join(root, f),'r')

How did you expect the "open" function to know that the string "1" is supposed to mean "/home/des/test/1" (unless "/home/des/test" happens to be your current working directory)?

Is very simple. when it says 'Could not locate Gemfile' it means in the folder you are currently in or a directory you are in, there is No a file named GemFile. Therefore in your command prompt give an explicit or full path of the there folder where such file name "Gemfile" is e.g cd C:\Users\Administrator\Desktop\RubyProject\demo.

It will definitely be solved in a minute.

As a side note, you also should keep in mind that "escaping" means "using the back-slash as an indicator for special characters". You can put an end of line in a string doing that, for instance:

String foo = "Hello\

There";

Unless you're talking about base 16 numbers (for which there's a method to parse as Hex), you need to explicitly separate out the part that you are interested in, and then convert it. After all, what would be the semantics of something like 23e44e11d in base 10?

Regular expressions could do the trick if you know for sure that you only have one number. Java has a built in regular expression parser.

If, on the other hands, your goal is to concatenate all the digits and dump the alphas, then that is fairly straightforward to do by iterating character by character to build a string with StringBuilder, and then parsing that one.

That's easy! First, give your button an id such as <input type="button" value="I am a button!" id="myButton" /> Then, for height, and width, use CSS code:

.myButton {
    width: 100px;
    height: 100px;
}

You could also do this CSS:

input[type="button"] {
    width: 100px;
    height: 100px;
}

But that would affect all the buttons on the Page.

Working example - JSfiddle

Fetch both the key and the value from the dictionary in the loop:

{% for key, value in mydict.items %}
    {{ value }}
{% endfor %}

I find this easier to read and it avoids the need for special coding. I usually need the key and the value inside the loop anyway.

I understand that my comment relate with windows, but may be someone be useful. For win run in cmd:

wmic process  where "commandline like '%my_app.js%' AND name='node.exe' " CALL Terminate

then you can run your app again:

node my_app.js

Also you can use it in batch file, with escape quotes:

wmic process  where "commandline like '%%my_app.js%%' AND name='node.exe' " CALL Terminate
node my_app.js

If you could do this, it will represent a big security problem, as you can access your filesystem, and potentially act on the data available there... Luckily it's not possible to do what you're trying to do.

If you need local resources to be accessed, you can try to start a web server on your machine, and in this case your method will work. Other workarounds are possible, such as acting on Chrome settings, but I always prefer the clean way, installing a local web server, maybe on a different port (no, it's not so difficult!).

If you don't need mutability for your final map, there is Guava's ImmutableMap with its Builder and putAll method which, in contrast to Java's Map interface method, can be chained.

Example of use:

Map<String, Integer> mergeMyTwoMaps(Map<String, Integer> map1, Map<String, Integer> map2) {
  return ImmutableMap.<String, Integer>builder()
      .putAll(map1)
      .putAll(map2)
      .build();
}

Of course, this method can be more generic, use varargs and loop to putAll Maps from arguments etc. but I wanted to show a concept.

Also, ImmutableMap and its Builder have few limitations (or maybe features?):

• they are null hostile (throw NullPointerException - if any key or value in map is null)
• Builder don't accept duplicate keys (throws IllegalArgumentException if duplicate keys were added).

Figure sizes are specified in inches and can be included as a global option of the document output format. For example:

---
title: "My Document"
output:
  html_document:
    fig_width: 6
    fig_height: 4
---

And the plot's size in the graphic device can be increased at the chunk level:

```{r, fig.width=14, fig.height=12}          #Expand the plot width to 14 inches

ggplot(aes(x=mycolumn1, y=mycolumn2)) +     #specify the x and y aesthetic
geom_line(size=2) +                         #makes the line thicker
theme_grey(base_size = 25)                  #increases the size of the font
```

You can also use the out.width and out.height arguments to directly define the size of the plot in the output file:

```{r, out.width="200px", out.height="200px"} #Expand the plot width to 200 pixels

ggplot(aes(x=mycolumn1, y=mycolumn2)) +     #specify the x and y aesthetic
geom_line(size=2) +                         #makes the line thicker
theme_grey(base_size = 25)                  #increases the size of the font
```

I know this is late, but this is how I normally do it,

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();           
InputStream stream = classLoader.getResourceAsStream("../test/foo.txt");

This worked for me:

ActiveWindow.SmallScroll down:=0

or more simply:

ActiveWindow.SmallScroll 0

This might help to match balanced parenthesis.

\s*\w+[(][^+]*[)]\s*

Agree with Gray, as you may need your pattern to have both litrals (\[, \]) and meta-characters ([, ]). so with some utility you should be able to escape all character first and then you can add meta-characters you want to add on same pattern.

Use get_the_category() like this:

<?php
foreach((get_the_category()) as $category) { 
    echo $category->cat_name . ' '; 
} 
?>

It returns a list because a post can have more than one category.

The documentation also explains how to do this from outside the loop.

1. Use conditional formatting instead of VBA to highlight errors.

2. Using a VBA loop like the one you posted will take a long time to process

3. the statement If cell.Value = "#N/A" Then will never work. If you insist on using VBA to highlight errors, try this instead.

   Sub ColorCells()

   Dim Data As Range
   Dim cell As Range
   Set currentsheet = ActiveWorkbook.Sheets("Comparison")
   Set Data = currentsheet.Range("A2:AW1048576")
   
   For Each cell In Data
   
   If IsError(cell.Value) Then
      cell.Interior.ColorIndex = 3
   End If
   Next
   
   End Sub
   

4. Be prepared for a long wait, since the procedure loops through 51 million cells

5. There are more efficient ways to achieve what you want to do. Update your question if you have a change of mind.

You can use below SQL to read the BLOB Fields from table.

SELECT DBMS_LOB.SUBSTR(BLOB_FIELD_NAME) FROM TABLE_NAME;

That's how I am able to do with the help of solution given by @tdammers below. The following line will be placed inside foreach loop.

$array[] = array('power' => trim("Some value"), 'time' => "time here" );

And then encode the array with json encode function

json_encode(array('newvalue'=> $array), 200)

For those who have noticed desktop navbars flicker when using this solution:

$('.nav a').on('click', function(){
    $(".navbar-collapse").collapse('hide');
}); 

A simple solution to that problem is to reference the collapsed navbar only by checking for the presence of 'in':

$('.navbar-collapse .nav a').on('click', function(){
    if($('.navbar-collapse').hasClass('in'))
    {
        $(".navbar-collapse").collapse('hide');
    }
});

This collapses the navbar on click when the navbar is in mobile mode, but will leave alone the desktop version. This avoids the flickering many people have witnessed occurring on desktop versions.

Additionally, if you have a navbar with dropdown menus you won't be able to see these as the navbar will be hidden as soon as you click on them, so if you have dropdown menus (like I do!), use the following:

$('.nav a').on('click', function(e){
    if(!$(this).closest('li').hasClass('dropdown') & $( '.navbar-collapse').hasClass('in'))
    {
        $(".navbar-collapse").collapse('hide');
    }
});

This looks for the presence of the dropdown class above the link clicked on in the DOM, if it exists, then the link was intending to launch a drop down menu and consequently the menu isn't hidden. When you click on a link within the dropdown menu, the navbar will hide correctly.

I was only using full screen mode to hide the status bar. However, I want the app to resize when keyboard is shown. All of the other solutions (likely due to age of post) were complicated or not possible for my use (want to avoid change Java code for sack of PhoneGap Build).

Instead of using Full screen, I modified my configure for Android to be non-fullscreen:

            <preference name="fullscreen" value="false" />

And added the cordova-plugin-statusbar, via command line:

cordova plugin add cordova-plugin-statusbar

When app has loaded, I simple call a method on the plugin to hide itself, like:

    if (window.cordova && window.cordova.platformId == 'android' && window.StatusBar)
        window.StatusBar.hide();

This works like a charm. Only real downside is that the status bar is breifly visible while the app loads. For my needs, that wasn't an issue.

If you just have included a layout file at the beginning of onCreate() inside setContentView and want to get this layout to add new elements programmatically try this:

ViewGroup linearLayout = (ViewGroup) findViewById(R.id.linearLayoutID);

then you can create a new Button for example and just add it:

Button bt = new Button(this);
bt.setText("A Button");
bt.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, 
                                    LayoutParams.WRAP_CONTENT));
linerLayout.addView(bt);

What you are doing is printing the value in the array at spot [3][3], which is invalid for a 3by3 array, you need to loop over all the spots and print them.

for(int i = 0; i < 3; i++) {
    for(int j = 0; j < 3; j++) {
        printf("%d ", array[i][j]);
    }
    printf("\n");
} 

This will print it in the following format

10 23 42
1 654 0
40652 22 0

if you want more exact formatting you'll have to change how the printf is formatted.

Define these variables in the class:

int PICK_IMAGE_MULTIPLE = 1; 
String imageEncoded;    
List<String> imagesEncodedList;

Let's Assume that onClick on a button it should open gallery to select images

 Intent intent = new Intent();
 intent.setType("image/*");
 intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
 intent.setAction(Intent.ACTION_GET_CONTENT);
 startActivityForResult(Intent.createChooser(intent,"Select Picture"), PICK_IMAGE_MULTIPLE);

Then you should override onActivityResult Method

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    try {
        // When an Image is picked
        if (requestCode == PICK_IMAGE_MULTIPLE && resultCode == RESULT_OK
                    && null != data) {
            // Get the Image from data

            String[] filePathColumn = { MediaStore.Images.Media.DATA };
            imagesEncodedList = new ArrayList<String>();
            if(data.getData()!=null){

                Uri mImageUri=data.getData();

                // Get the cursor
                Cursor cursor = getContentResolver().query(mImageUri,
                            filePathColumn, null, null, null);
                // Move to first row
                cursor.moveToFirst();

                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                imageEncoded  = cursor.getString(columnIndex);
                cursor.close();

            } else {
                if (data.getClipData() != null) {
                    ClipData mClipData = data.getClipData();
                    ArrayList<Uri> mArrayUri = new ArrayList<Uri>();
                    for (int i = 0; i < mClipData.getItemCount(); i++) {

                        ClipData.Item item = mClipData.getItemAt(i);
                        Uri uri = item.getUri();
                        mArrayUri.add(uri);
                        // Get the cursor
                        Cursor cursor = getContentResolver().query(uri, filePathColumn, null, null, null);
                        // Move to first row
                        cursor.moveToFirst();

                        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                        imageEncoded  = cursor.getString(columnIndex);
                        imagesEncodedList.add(imageEncoded);
                        cursor.close();

                    }
                    Log.v("LOG_TAG", "Selected Images" + mArrayUri.size());
                }
            }
        } else {
            Toast.makeText(this, "You haven't picked Image",
                        Toast.LENGTH_LONG).show();
        }
    } catch (Exception e) {
        Toast.makeText(this, "Something went wrong", Toast.LENGTH_LONG)
                    .show();
    }

    super.onActivityResult(requestCode, resultCode, data);
}

NOTE THAT: the gallery doesn't give you the ability to select multi-images so we here open all images studio that you can select multi-images from them. and don't forget to add the permissions to your manifest

VERY IMPORTANT: getData(); to get one single image and I've stored it here in imageEncoded String if the user select multi-images then they should be stored in the list

So you have to check which is null to use the other

Wish you have a nice try and to others

Here, I put my answer and its working for swift 4.2.

MKMapView center and zoom in

git config credential.helper store

Note: While this is convenient, Git will store your credentials in clear text in a local file (.git-credentials) under your project directory (see below for the "home" directory). If you don't like this, delete this file and switch to using the cache option.

If you want Git to resume to asking you for credentials every time it needs to connect to the remote repository, you can run this command:

git config --unset credential.helper

To store the passwords in .git-credentials in your %HOME% directory as opposed to the project directory: use the --global flag

git config --global credential.helper store

It is saying the value is undefined because it is a constructor function, not a class with a constructor. In order to use it, you would need to use Customer() or customer().

First, you need to load file1.js before file2.js, like slebetman said:

<script defer src="file1.js" type="module"></script>
<script defer src="file2.js" type="module"></script>

Then, you could change your file1.js as follows:

export default class Customer(){
    constructor(){
        this.name="Jhon";
        this.getName=function(){
            return this.name;
        };
    }
}

And the file2.js as follows:

import { Customer } from "./file1";
var customer=new Customer();

Please correct me if I am wrong.

your solution is

var i;
for(i=10; i>=0; i= i-1){
   var s;
   for(s=0; s<i; s = s+1){
    document.write("*");
   }
   //printing new line
   document.write("<br>");
}

Their synchronization semantics are very different:

• mutexes allow serialization of access to a given resource i.e. multiple threads wait for a lock, one at a time and as previously said, the thread owns the lock until it is done: only this particular thread can unlock it.
• a binary semaphore is a counter with value 0 and 1: a task blocking on it until any task does a sem_post. The semaphore advertises that a resource is available, and it provides the mechanism to wait until it is signaled as being available.

As such one can see a mutex as a token passed from task to tasks and a semaphore as traffic red-light (it signals someone that it can proceed).

Disabled means that no data from that form element will be submitted when the form is submitted. Read-only means any data from within the element will be submitted, but it cannot be changed by the user.

For example:

<input type="text" name="yourname" value="Bob" readonly="readonly" />

This will submit the value "Bob" for the element "yourname".

<input type="text" name="yourname" value="Bob" disabled="disabled" />

This will submit nothing for the element "yourname".

The most safe way is probably overriding keys method that is used to generate output:

new JSONObject(){
  @Override
  public Iterator keys(){
    TreeSet<Object> sortedKeys = new TreeSet<Object>();
    Iterator keys = super.keys();
    while(keys.hasNext()){
      sortedKeys.add(keys.next());
    }
    return sortedKeys.iterator();
  }
};

Cellspacing is all around the cell and cannot be changed (i.e. if it's set to one, there will be 1 pixel of space on all sides). Padding can be specified discreetly (e.g. padding-top, padding-bottom, padding-left, and padding-right; or padding: [top] [right] [bottom] [left];).

You can use reptyr:

sudo apt install reptyr
reptyr pid

Just in case, I had similar error with bundler 2.1.2 and solved it with:

sudo gem install bundler -v 1.17.3

If you have several bundler versions installed, then you can run specific version of bundle this way: bundle _1.17.3_ exec rspec

Though seems like later bundler versions are pretty buggy (had issues on 3 different projects on 2 operation systems), having one old bundler may work the best, at least this is what I have on my Ubuntu & MacOS

Latest bundler versions may override stable bundler -v 1.17.3. It can be not easy to remove latest bundler from system, here is what helped me:

• Remove default version: https://stackoverflow.com/a/60550744/1751321
• Remove bundler.rb and bundler folder from load paths: ruby -e 'puts $LOAD_PATH'
• Then reinstall stable bundler -v 1.17.3

The filter design method in accepted answer is correct, but it has a flaw. SciPy bandpass filters designed with b, a are unstable and may result in erroneous filters at higher filter orders.

Instead, use sos (second-order sections) output of filter design.

from scipy.signal import butter, sosfilt, sosfreqz

def butter_bandpass(lowcut, highcut, fs, order=5):
        nyq = 0.5 * fs
        low = lowcut / nyq
        high = highcut / nyq
        sos = butter(order, [low, high], analog=False, btype='band', output='sos')
        return sos

def butter_bandpass_filter(data, lowcut, highcut, fs, order=5):
        sos = butter_bandpass(lowcut, highcut, fs, order=order)
        y = sosfilt(sos, data)
        return y

Also, you can plot frequency response by changing

b, a = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = freqz(b, a, worN=2000)

to

sos = butter_bandpass(lowcut, highcut, fs, order=order)
w, h = sosfreqz(sos, worN=2000)

Use MySQL's STR_TO_DATE() function to parse the string that you're attempting to insert:

INSERT INTO tblInquiry (fldInquiryReceivedDateTime) VALUES
  (STR_TO_DATE('5/15/2012 8:06:26 AM', '%c/%e/%Y %r'))

I tried to to get these suggestions to work for a textblock, but couldn't get it to work. I even tried to get it to work from the designer. (Look in Layout and expand the list by clicking the down-arrow "V" at the bottom) I tried setting the scrollviewer to Visible and then Auto, but it still wouldn't work.

I eventually gave up and changed the TextBlock to a TextBox with the Readonly attribute set, and it worked like a charm.

Error is that you are using 'ID' in lower case like 'checkbox1' but when you loop json object its return in upper case. So you need to replace checkbox1 to CHECKBOX1.

In my case :-

var response = jQuery.parseJSON(response);

$.each(response, function(key, value) {
   $.each(value, function(key, value){
        $('#'+key).val(value);
   });
});

Before

  <input type="text" name="abc" id="abc" value="">

I am getting the same error but when i replace the id in html code its work fine.

After

<input type="text" name="abc" id="ABC" value="">

what about a one-liner using String.split()?

String s = "foo,bar,c;qual=\"baz,blurb\",d;junk=\"quux,syzygy\"";
String[] split = s.split( "(?<!\".{0,255}[^\"]),|,(?![^\"].*\")" );

Bit heavy because of using pandas but works:

import pandas as pd
pd.to_datetime(msec_from_java, unit='ms').to_pydatetime()

to pass the event object:

<p id="p" onclick="doSomething(event)">

to get the clicked child element (should be used with event parameter:

function doSomething(e) {
    e = e || window.event;
    var target = e.target || e.srcElement;
    console.log(target);
}

to pass the element itself (DOMElement):

<p id="p" onclick="doThing(this)">

see live example on jsFiddle.

You can specify the name of the event as above, but alternatively your handler can access the event parameter as described here: "When the event handler is specified as an HTML attribute, the specified code is wrapped into a function with the following parameters". There's much more additional documentation at the link.

If you just want to show label below the marker, then you can extend google maps Marker to add a setter method for label and you can define the label object by extending google maps overlayView like this..

<script type="text/javascript">
    var point = { lat: 22.5667, lng: 88.3667 };
    var markerSize = { x: 22, y: 40 };


    google.maps.Marker.prototype.setLabel = function(label){
        this.label = new MarkerLabel({
          map: this.map,
          marker: this,
          text: label
        });
        this.label.bindTo('position', this, 'position');
    };

    var MarkerLabel = function(options) {
        this.setValues(options);
        this.span = document.createElement('span');
        this.span.className = 'map-marker-label';
    };

    MarkerLabel.prototype = $.extend(new google.maps.OverlayView(), {
        onAdd: function() {
            this.getPanes().overlayImage.appendChild(this.span);
            var self = this;
            this.listeners = [
            google.maps.event.addListener(this, 'position_changed', function() { self.draw();    })];
        },
        draw: function() {
            var text = String(this.get('text'));
            var position = this.getProjection().fromLatLngToDivPixel(this.get('position'));
            this.span.innerHTML = text;
            this.span.style.left = (position.x - (markerSize.x / 2)) - (text.length * 3) + 10 + 'px';
            this.span.style.top = (position.y - markerSize.y + 40) + 'px';
        }
    });
    function initialize(){
        var myLatLng = new google.maps.LatLng(point.lat, point.lng);
        var gmap = new google.maps.Map(document.getElementById('map_canvas'), {
            zoom: 5,
            center: myLatLng,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        });
        var myMarker = new google.maps.Marker({
            map: gmap,
            position: myLatLng,
            label: 'Hello World!',
            draggable: true
        });
    }
</script>
<style>
    .map-marker-label{
        position: absolute;
    color: blue;
    font-size: 16px;
    font-weight: bold;
    }
</style>

This will work.

Why invent wheels yourself while there is a car ready for you? I just find this tools super easy and intuitive to use: Advanced Installer. This one minute video should be enough to impress you. Here is the illustrative user guide.

Do you have an empty __init__.py file in both directories to let python know that the dirs are modules?

The basic outline when you are not running from within the folder (ie maybe from pylint's, though I haven't used that) is:

topdir\
  __init__.py
  functions_etc.py
  subdir\
    __init__.py
    other_functions.py

This is how the python interpreter is aware of the module without reference to the current directory, so if pylint is running from its own absolute path it will be able to access functions_etc.py as topdir.functions_etc or topdir.subdir.other_functions, provided topdir is on the PYTHONPATH.

UPDATE: If the problem is not the __init__.py file, maybe just try copying or moving your module to c:\Python26\Lib\site-packages -- that is a common place to put additional packages, and will definitely be on your pythonpath. If you know how to do Windows symbolic links or the equivalent (I don't!), you could do that instead. There are many more options here: http://docs.python.org/install/index.html, including the option of appending sys.path with the user-level directory of your development code, but in practice I usually just symbolically link my local development dir to site-packages - copying it over has the same effect.

The easiest way to for-each every char in a String is to use toCharArray():

for (char ch: "xyz".toCharArray()) {
}

This gives you the conciseness of for-each construct, but unfortunately String (which is immutable) must perform a defensive copy to generate the char[] (which is mutable), so there is some cost penalty.

From the documentation:

[toCharArray() returns] a newly allocated character array whose length is the length of this string and whose contents are initialized to contain the character sequence represented by this string.

There are more verbose ways of iterating over characters in an array (regular for loop, CharacterIterator, etc) but if you're willing to pay the cost toCharArray() for-each is the most concise.

In Java you can only import class Names, or static methods/fields.

To import class use

import full.package.name.of.SomeClass;

to import static methods/fields use

import static full.package.name.of.SomeClass.staticMethod;
import static full.package.name.of.SomeClass.staticField;

Alternative solution: A More Userfriendly solution than command line:

If you are looking for a user friendly way to send and request data using HTTP Methods other than simple GET's probably you are looking for a chrome extention just like this one http://goo.gl/rVW22f called AVANCED REST CLIENT

For guys looking to stay with command-line i recommend cygwin:

I ended up installing cygwin with CURL which allow us to Get that Linux feeling - on Windows!

Using Cygwin command line this issues have stopped and most important, the request syntax used on 1. worked fine.

Useful links:

Where i was downloading the curl for windows command line?

I hope it helps someone because i spent all morning on this.

Hemant and Vikram's answers didn't quite work for me outright in Chrome. The event.preventDefault(); script prevented the the page from submitting regardless of passing or failing the validation. Instead, I had to move the event.preventDefault(); into the if statement as follows:

    if(check if your conditions are not satisfying) 
    { 
    event.preventDefault();
    alert("validation failed false");
    returnToPreviousPage();
    return false;
    }
    alert("validations passed");
    return true;
    }

Thanks to Hemant and Vikram for putting me on the right track.

This code works for me:

import groovy.io.FileType

def list = []

def dir = new File("path_to_parent_dir")
dir.eachFileRecurse (FileType.FILES) { file ->
  list << file
}

Afterwards the list variable contains all files (java.io.File) of the given directory and its subdirectories:

list.each {
  println it.path
}

Using Java 8+ features we can write the code in few lines:

protected static Collection<Path> find(String fileName, String searchDirectory) throws IOException {
    try (Stream<Path> files = Files.walk(Paths.get(searchDirectory))) {
        return files
                .filter(f -> f.getFileName().toString().equals(fileName))
                .collect(Collectors.toList());

    }
}

Files.walk returns a Stream<Path> which is "walking the file tree rooted at" the given searchDirectory. To select the desired files only a filter is applied on the Stream files. It compares the file name of a Path with the given fileName.

Note that the documentation of Files.walk requires

This method must be used within a try-with-resources statement or similar control structure to ensure that the stream's open directories are closed promptly after the stream's operations have completed.

I'm using the try-resource-statement.

For advanced searches an alternative is to use a PathMatcher:

protected static Collection<Path> find(String searchDirectory, PathMatcher matcher) throws IOException {
    try (Stream<Path> files = Files.walk(Paths.get(searchDirectory))) {
        return files
                .filter(matcher::matches)
                .collect(Collectors.toList());

    }
}

An example how to use it to find a certain file:

public static void main(String[] args) throws IOException {
    String searchDirectory = args[0];
    String fileName = args[1];
    PathMatcher matcher = FileSystems.getDefault().getPathMatcher("regex:.*" + fileName);
    Collection<Path> find = find(searchDirectory, matcher);
    System.out.println(find);
}

Just in case: why don't you use find?

find -iname '*.mp3' -o -iname '*.exe' -o -iname '*.mp4'

If your project is on GitHub, you now (April 2013) have Pulse (see "Get up to speed with Pulse"):

It is more limited, and won't display all the stats you might need, but is readily available for any GitHub project.

Pulse is a great way to discover recent activity on projects.
Pulse will show you who has been actively committing and what has changed in a project's default branch:

You can find the link to the left of the nav bar.

Note that there isn't (yet) an API to extract that information.

Make sure of the conflict origin: if it is the result of a git merge, see Brian Campbell's answer.

But if is the result of a git rebase, in order to discard remote (their) changes and use local changes, you would have to do a:

git checkout --theirs -- .

See "Why is the meaning of “ours” and “theirs” reversed"" to see how ours and theirs are swapped during a rebase (because the upstream branch is checked out).

For MacOS Maveriks (10.9 and perhaps later versions too), Apache Ant does not come bundled with the operating system and so must be installed manually. You can use brew to easily install ant. Simply execute the following command in a terminal window to install brew:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

It's a medium sized download which took me 10min to download and install. Just follow the process which involves installing various components. If you already have brew installed, make sure it's up to date by executing:

brew update

Once installed you can simply type:

brew install ant

Ant is now installed and available through the "ant" command in the terminal.

To test the installation, just type "ant -version" into a terminal window. You should get the following output:

Apache Ant(TM) version X.X.X compiled on MONTH DAY YEAR

Source: Error executing command 'ant' on Mac OS X 10.9 Mavericks when building for Android with PhoneGap/Cordova

If you are getting errors installing Brew, try uninstalling first using the command:

rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup

The Easiest way to do it is to have good site structure and write it as a constant.

Here look at how I done it; Jsfiddle

With the Code I put in, I managed to get it working on Webkit (Chrome/Safari) and Firefox. I don't know if it works with the latest version of Opera. Yes it does work under the latest version of Opera.

#wrapper {
  width: 300px; height: 300px;
  border-radius: 100px;
  overflow: hidden;
  position: absolute; /* this breaks the overflow:hidden in Chrome/Opera */
}

#box {
  width: 300px; height: 300px;
  background-color: #cde;
  border-radius: 100px;
  -webkit-border-radius: 100px;
  -moz-border-radius: 100px;
  -o-border-radius: 100px;
}

1. make sure you have "expect" tool before, if not, do it

   # apt-get install expect

2. create the a script file with following content. (# vi /root/scriptfile)

   spawn scp /path_from/file_name user_name_here@to_host_name:/path_to

   expect "password:"

   send put_password_here\n;

   interact

3. execute the script file with "expect" tool

   # expect /root/scriptfile

Open task manager and kill adb.exe, now adb will start normally

Probably not what you want to hear, but a "feeds" table would be a great middleman for this sort of transaction, giving you a denormalized way of pivoting to all these data with a polymorphic relationship.

You could build it like this:

<?php

Schema::create('feeds', function($table) {
    $table->increments('id');
    $table->timestamps();
    $table->unsignedInteger('user_id');
    $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
    $table->morphs('target'); 
});

Build the feed model like so:

<?php

class Feed extends Eloquent
{
    protected $fillable = ['user_id', 'target_type', 'target_id'];

    public function user()
    {
        return $this->belongsTo('User');
    }

    public function target()
    {
        return $this->morphTo();
    }
}

Then keep it up to date with something like:

<?php

Vote::created(function(Vote $vote) {
    $target_type = 'Vote';
    $target_id   = $vote->id;
    $user_id     = $vote->user_id;

    Feed::create(compact('target_type', 'target_id', 'user_id'));
});

You could make the above much more generic/robust—this is just for demonstration purposes.

At this point, your feed items are really easy to retrieve all at once:

<?php

Feed::whereIn('user_id', $my_friend_ids)
    ->with('user', 'target')
    ->orderBy('created_at', 'desc')
    ->get();

wget url or curl url where url is a url of the tomcat server that should be available, for example: wget http://localhost:8080. Then check the exit code, if it's 0 - tomcat is up.

This probably doesn't really answer your question but you might find it useful anyway.

The first command creates the script that's displayed by the second command.

The third command makes that script executable.

The fourth command provides a usage example.

john@malkovich:~/tmp/so$ echo $'#!/usr/bin/env python\nimport textwrap, sys\n\ndef bash_dedent(text):\n    """Dedent all but the first line in the passed `text`."""\n    try:\n        first, rest = text.split("\\n", 1)\n        return "\\n".join([first, textwrap.dedent(rest)])\n    except ValueError:\n        return text  # single-line string\n\nprint bash_dedent(sys.argv[1])'  > bash_dedent
john@malkovich:~/tmp/so$ cat bash_dedent 
#!/usr/bin/env python
import textwrap, sys

def bash_dedent(text):
    """Dedent all but the first line in the passed `text`."""
    try:
        first, rest = text.split("\n", 1)
        return "\n".join([first, textwrap.dedent(rest)])
    except ValueError:
        return text  # single-line string

print bash_dedent(sys.argv[1])
john@malkovich:~/tmp/so$ chmod a+x bash_dedent
john@malkovich:~/tmp/so$ echo "$(./bash_dedent "first line
>     second line
>     third line")"
first line
second line
third line

Note that if you really want to use this script, it makes more sense to move the executable script into ~/bin so that it will be in your path.

Check the python reference for details on how textwrap.dedent works.

If the usage of $'...' or "$(...)" is confusing to you, ask another question (one per construct) if there's not already one up. It might be nice to provide a link to the question you find/ask so that other people will have a linked reference.

One can also use the following syntax in typescript. Note the backtick " ` "

window.location.hash = `${page_number}`

The differences are listed in the Javadoc for ListIterator

You can

• iterate backwards
• obtain the iterator at any point.
• add a new value at any point.
• set a new value at that point.

select count(*) 
from table_emp 
 where DATEPART(YEAR, ARR_DATE) = '2012' AND DATEPART(MONTH, ARR_DATE) = '01'

Use the gca ("get current axes") helper function:

ax = plt.gca()

Example:

import matplotlib.pyplot as plt
import matplotlib.finance
quotes = [(1, 5, 6, 7, 4), (2, 6, 9, 9, 6), (3, 9, 8, 10, 8), (4, 8, 8, 9, 8), (5, 8, 11, 13, 7)]
ax = plt.gca()
h = matplotlib.finance.candlestick(ax, quotes)
plt.show()

Here I'm offering a generic function for multiple set intersection trying to take advantage of the best method available:

def multiple_set_intersection(*sets):
    """Return multiple set intersection."""
    try:
        return set.intersection(*sets)
    except TypeError: # this is Python < 2.6 or no arguments
        pass

    try: a_set= sets[0]
    except IndexError: # no arguments
        return set() # return empty set

    return reduce(a_set.intersection, sets[1:])

Guido might dislike reduce, but I'm kind of fond of it :)

Its simple. Just use css.

<style>
@page { size: auto;  margin: 0mm; }
</style>

You can always use System.Resources.ResourceManager which returns the cached ResourceManager used by this class. Since chan1 and chan2 represent two different images, you may use System.Resources.ResourceManager.GetObject(string name) which returns an object matching your input with the project resources

Example

object O = Resources.ResourceManager.GetObject("chan1"); //Return an object from the image chan1.png in the project
channelPic.Image = (Image)O; //Set the Image property of channelPic to the returned object as Image

Notice: Resources.ResourceManager.GetObject(string name) may return null if the string specified was not found in the project resources.

Thanks,
I hope you find this helpful :)

Brody's solution worked perfect for me. I have had to add side views on a textfield and add additional padding. So by implementing the custom UIEdgeInsets property to a UITextField subclass I have managed to achieve the task. I'm going to use this new subclass in all of my projects.

The above is fine. Do you mind if I ask you a question - Is this causing you a problem? It seams to me you are optimizing before you know if you need to.

Now for my over engineered solution. In many (thou not all) cases you can use CharSequence instead of a String.

public class OneCharSequence implements CharSequence {
  private final char value;
  private final int length;
  public OneCharSequence(final char value, final int length) {
    this.value = value;
    this.length = length;
  }
  public char   charAt(int index)  {
     if(index < length) return value;
     throw new IndexOutOfBoundsException();
  }
  public int length() {
    return length;
  }
  public CharSequence subSequence(int start, int end) {
     return new OneCharSequence(value, (end-start));
  }
  public String toString() {
    char[] array = new char[length];
    Arrays.fill(array, value);
    return new String(array);
  }
}

Simply use this:

public static List<String> GetAllFiles(String directory)
{
    return Directory.GetFiles(directory, "*.*", SearchOption.AllDirectories).ToList();
}

And if you want every file, even extensionless ones:

public static List<String> GetAllFiles(String directory)
{
    return Directory.GetFiles(directory, "*", SearchOption.AllDirectories).ToList();
}

For raw files, you should consider creating a raw folder inside res directory and then call getResources().openRawResource(resourceName) from your activity.

If you need a conversion other than your server's location, here is a function that allows you to pass a standard offset and accounts for US Daylight Savings Times:

    set @SSM = datename(year,@UTC) + '0314' 
    set @SSM = dateadd(hour,2,dateadd(day,datepart(dw,@SSM)*-1+1,@SSM))
    set @FSN = datename(year,@UTC) + '1107'
    set @FSN = dateadd(second,-1,dateadd(hour,2,dateadd(day,datepart(dw,@FSN)*-1+1,@FSN)))

    -- add an hour to @StandardOffset if @UTC is in DST range

        set @StandardOffset = @StandardOffset + 1

    -- convert to DST
    set @DST = dateadd(hour,@StandardOffset,@UTC)

    -- return converted datetime
    return @DST

how to use

color.toHex()

I think you can use the Application class for many things, but they are all tied to your need to do some stuff BEFORE any of your Activities or Services are started. For instance, in my application I use custom fonts. Instead of calling

Typeface.createFromAsset()

from every Activity to get references for my fonts from the Assets folder (this is bad because it will result in memory leak as you are keeping a reference to assets every time you call that method), I do this from the onCreate() method in my Application class:

private App appInstance;
Typeface quickSandRegular;
...
public void onCreate() {
    super.onCreate();

    appInstance = this;
    quicksandRegular = Typeface.createFromAsset(getApplicationContext().getAssets(),
                       "fonts/Quicksand-Regular.otf");
   ...
   }

Now, I also have a method defined like this:

public static App getAppInstance() {
    return appInstance;
}

and this:

public Typeface getQuickSandRegular() {
    return quicksandRegular;
}

So, from anywhere in my application, all I have to do is:

App.getAppInstance().getQuickSandRegular()

Another use for the Application class for me is to check if the device is connected to the Internet BEFORE activities and services that require a connection actually start and take necessary action.

If you are using Toad for MySQL steps to import a file is as follows:

1. create a table in MySQL with the same columns that of the file to be imported.
2. now the table is created, goto > Tools > Import > Import Wizard
3. now in the import wizard dialogue box, click Next.
4. click Add File, browse and select the file to be imported.
5. choose the correct dilimination.("," seperated for .csv file)
6. click Next, check if the mapping is done properly.
7. click Next, select the "A single existing table" radio button also select the table that to be mapped from the dropdown menu of Tables.
8. Click next and finish the process.

Realistically for an application, more then 4000-5000 open sockets on a single machine becomes impractical. Just checking for activity on all the sockets and managing them starts to become a performance issue - especially in real-time environments.

Right now (August 2014) You could use RStudio for converting R Markdown to PDF. Basically, RStudio use pandoc to convert Rmd to PDF.

You could change metadata to:

1. Add table of contents
2. Change figure options
3. Change syntax highlighting style
4. Add LaTeX options
5. And many more...

I have looked at software protection in general for my own projects and the general philosophy is that complete protection is impossible. The only thing that you can hope to achieve is to add protection to a level that would cost your customer more to bypass than it would to purchase another license.

With that said I was just checking google for python obsfucation and not turning up a lot of anything. In a .Net solution, obsfucation would be a first approach to your problem on a windows platform, but I am not sure if anyone has solutions on Linux that work with Mono.

The next thing would be to write your code in a compiled language, or if you really want to go all the way, then in assembler. A stripped out executable would be a lot harder to decompile than an interpreted language.

It all comes down to tradeoffs. On one end you have ease of software development in python, in which it is also very hard to hide secrets. On the other end you have software written in assembler which is much harder to write, but is much easier to hide secrets.

Your boss has to choose a point somewhere along that continuum that supports his requirements. And then he has to give you the tools and time so you can build what he wants. However my bet is that he will object to real development costs versus potential monetary losses.

This seems to be the simplest regular expression of all that I found

(?:<TAG>)([\s\S]*)(?:<\/TAG>)

1. Exclude opening tag (?:<TAG>) from the matches
2. Include any whitespace or non-whitespace characters ([\s\S]*) in the matches
3. Exclude closing tag (?:<\/TAG>) from the matches

This may be created sql injection point "SQL Injection Piggy-backed Queries". attackers able to append multiple malicious sql statements. so do not append user inputs directly to the queries.

Security considerations

The API functions mysqli_query() and mysqli_real_query() do not set a connection flag necessary for activating multi queries in the server. An extra API call is used for multiple statements to reduce the likeliness of accidental SQL injection attacks. An attacker may try to add statements such as ; DROP DATABASE mysql or ; SELECT SLEEP(999). If the attacker succeeds in adding SQL to the statement string but mysqli_multi_query is not used, the server will not execute the second, injected and malicious SQL statement.

It should work. Try this

var label:UILabel = UILabel(frame: CGRectMake(10
    ,100, 300, 40));
label.textAlignment = NSTextAlignment.Center;
label.numberOfLines = 0;
label.font = UIFont.systemFontOfSize(16.0);
label.text = "First label\nsecond line";
self.view.addSubview(label);

Try this piece of code:

NSString *digit = [[sender titlelabel] text];
NSLog(@"%@", digit);

The message means that you have incorrect syntax for using the digit variable. If you're not sending it any message - you don't need any brackets.

Have you tried this?

Out = subprocess.Popen('/usr/local/bin/script hostname = actual_server_name -p LONGLIST'.split(), shell=False,stdout=subprocess.PIPE,stderr=subprocess.PIPE)

You can also specify a dependency not in a maven repository. Could be usefull when no central maven repository for your team exist or if you have a CI server

    <dependency>
        <groupId>com.stackoverflow</groupId>
        <artifactId>commons-utils</artifactId>
        <version>1.3</version>
        <scope>system</scope>
        <systemPath>${basedir}/lib/commons-utils.jar</systemPath>
    </dependency>

This solution worked for MacOS Sierra, and running MySQL version 8.0.11. Please make sure driver you have added in your build path - "add external jar" should match up with SQL version.

String url = "jdbc:mysql://localhost:3306/syscharacterEncoding=utf8&useSSL=false&serverTimezone=UTC&rewriteBatchedStatements=true";

There is a method specifically for this purpose:

data.splitlines()
['a,b,c', 'd,e,f', 'g,h,i', 'j,k,l']

You need DATE_SUB() OR DATE_ADD()

append([]int{1,2}, []int{3,4}...) will work. Passing arguments to ... parameters.

If f is variadic with a final parameter p of type ...T, then within f the type of p is equivalent to type []T.

If f is invoked with no actual arguments for p, the value passed to p is nil.

Otherwise, the value passed is a new slice of type []T with a new underlying array whose successive elements are the actual arguments, which all must be assignable to T. The length and capacity of the slice is therefore the number of arguments bound to p and may differ for each call site.

Given the function and calls

func Greeting(prefix string, who ...string)
Greeting("nobody")
Greeting("hello:", "Joe", "Anna", "Eileen")

To turn line numbers on by default in all cells at startup I recommend this link. I quote:

1. Navigate to your jupyter config directory, which you can find by typing the following at the command line:

   jupyter --config-dir
   

2. From there, open or create the custom folder.

3. In that folder, you should find a custom.js file. If there isn’t one, you should be able to create one. Open it in a text editor and add this code:

   define([
       'base/js/namespace',
       'base/js/events'
       ],
       function(IPython, events) {
           events.on("app_initialized.NotebookApp",
               function () {
                   IPython.Cell.options_default.cm_config.lineNumbers = true;
               }
           );
       }
   );
   

Assuming your json object from your GET request looks like the one you posted above simply do:

let list: string[] = [];

json.Results.forEach(element => {
    list.push(element.Id);
});

Or am I missing something that prevents you from doing it this way?

Something like this:

setUsers = function (data) {
    for (k in data) {
        user[k] = data[k];
    }
}

URL safe Base64 Encoding/Decoding

public static class Base64Url
{
    public static string Encode(string text)
    {
        return Convert.ToBase64String(Encoding.UTF8.GetBytes(text)).TrimEnd('=').Replace('+', '-')
            .Replace('/', '_');
    }

    public static string Decode(string text)
    {
        text = text.Replace('_', '/').Replace('-', '+');
        switch (text.Length % 4)
        {
            case 2:
                text += "==";
                break;
            case 3:
                text += "=";
                break;
        }
        return Encoding.UTF8.GetString(Convert.FromBase64String(text));
    }
}

You can restart the database on RDS Admin.

The default answer is to remove the item from whatever collection you're using as the GridView's DataSource.

If that option is undesirable then I recommend that you use the GridView's RowDataBound event to selectively set the row's (e.Row) Visible property to false.

1· Do I need these DLL's?

It depends since Dependency Walker is a little bit out of date and may report the wrong dependency.

2. Where can I get them?

most dlls can be found at https://www.dll-files.com

I believe they are supposed to located in C:\Windows\System32\Wer.dll and C:\Program Files\Internet Explorer\Ieshims.dll

For me leshims.dll can be placed at C:\Windows\System32\. Context: windows 7 64bit.

Please see this sample implementation of filter to understand how it works in Python 3:

def my_filter(function, iterable):
    """my_filter(function or None, iterable) --> filter object

    Return an iterator yielding those items of iterable for which function(item)
    is true. If function is None, return the items that are true."""
    if function is None:
        return (item for item in iterable if item)
    return (item for item in iterable if function(item))

The following is an example of how you might use filter or my_filter generators:

>>> greetings = {'hello'}
>>> spoken = my_filter(greetings.__contains__, ('hello', 'goodbye'))
>>> print('\n'.join(spoken))
hello

java.* packages are the core Java language packages, meaning that programmers using the Java language had to use them in order to make any worthwhile use of the java language.

javax.* packages are optional packages, which provides a standard, scalable way to make custom APIs available to all applications running on the Java platform.

PKCS#1 OAEP is an asymmetric cipher based on RSA and the OAEP padding

from Crypto.PublicKey import RSA
from Crypto import Random
from Crypto.Cipher import PKCS1_OAEP


def rsa_encrypt_decrypt():
    key = RSA.generate(2048)
    private_key = key.export_key('PEM')
    public_key = key.publickey().exportKey('PEM')
    message = input('plain text for RSA encryption and decryption:')
    message = str.encode(message)

    rsa_public_key = RSA.importKey(public_key)
    rsa_public_key = PKCS1_OAEP.new(rsa_public_key)
    encrypted_text = rsa_public_key.encrypt(message)
    #encrypted_text = b64encode(encrypted_text)

    print('your encrypted_text is : {}'.format(encrypted_text))


    rsa_private_key = RSA.importKey(private_key)
    rsa_private_key = PKCS1_OAEP.new(rsa_private_key)
    decrypted_text = rsa_private_key.decrypt(encrypted_text)

    print('your decrypted_text is : {}'.format(decrypted_text))

UPDATE: The really awesome code posted by Gabe Sechan no longer works unless you explicitly request the user to grant the necessary permissions. Here is some code that you can place in your main activity to request these permissions:

    if (getApplicationContext().checkSelfPermission(Manifest.permission.READ_PHONE_STATE)
            != PackageManager.PERMISSION_GRANTED) {
        // Permission has not been granted, therefore prompt the user to grant permission
        ActivityCompat.requestPermissions(this,
                new String[]{Manifest.permission.READ_PHONE_STATE},
                MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
    }

    if (getApplicationContext().checkSelfPermission(Manifest.permission.PROCESS_OUTGOING_CALLS)
            != PackageManager.PERMISSION_GRANTED) {
        // Permission has not been granted, therefore prompt the user to grant permission
        ActivityCompat.requestPermissions(this,
                new String[]{Manifest.permission.PROCESS_OUTGOING_CALLS},
                MY_PERMISSIONS_REQUEST_PROCESS_OUTGOING_CALLS);
    }

ALSO: As someone mentioned in a comment below Gabe's post, you have to add a little snippet of code, android:enabled="true, to the receiver in order to detect incoming calls when the app is not currently running in the foreground:

    <!--This part is inside the application-->
    <receiver android:name=".CallReceiver" android:enabled="true">
        <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
    </receiver>

There are very well answers here, but I want to add one line:

In android:onclick in XML, Android uses java reflection behind the scene to handle this.

And as explained here, reflection always slows down the performance. (especially on Dalvik VM). Registering onClickListener is a better way.

In JPA 2.1 you need to do the following

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Index;
import javax.persistence.Table;

@Entity(name="TEST_PERSON")
@Table(
    name="TEST_PERSON", 
    indexes = {
       @Index(name = "PERSON_INDX_0", columnList = "age"),
       @Index(name = "PERSON_INDX_1", columnList = "fName"),
       @Index(name = "PERSON_INDX_1", columnList = "sName")  })
public class TestPerson {

    @Column(name = "age", nullable = false)
    private int age;

    @Column(name = "fName", nullable = false)
    private String firstName;

    @Column(name = "sName", nullable = false)
    private String secondName;

    @Id
    private long id;

    public TestPerson() {
    }
}

In the above example the table TEST_PERSON will have 3 indexes:

• unique index on the primary key ID

• index on AGE

• compound index on FNAME, SNAME

Note 1: You get the compound index by having two @Index annotations with the same name

Note 2: You specify the column name in the columnList not the fieldName

Switch the order of the code: You're calling the click event before it is attached.

$(document).ready(function() {
      $("#checkbox_div input:radio").click(function() {

           alert("clicked");

      });

      $("input:radio:first").prop("checked", true).trigger("click");

});

raw_input is your helper here. From documentation -

If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised.

So your code will basically look like this.

num_array = list()
num = raw_input("Enter how many elements you want:")
print 'Enter numbers in array: '
for i in range(int(num)):
    n = raw_input("num :")
    num_array.append(int(n))
print 'ARRAY: ',num_array

P.S: I have typed all this free hand. Syntax might be wrong but the methodology is correct. Also one thing to note is that, raw_input does not do any type checking, so you need to be careful...

This is the very basic

awk '/pattern/{ print $0 }' file

ask awk to search for pattern using //, then print out the line, which by default is called a record, denoted by $0. At least read up the documentation.

If you only want to get print out the matched word.

awk '{for(i=1;i<=NF;i++){ if($i=="yyy"){print $i} } }' file

Make the list a character vector (not a vector of names)

rm(list = c('temp1','temp2'))

or

rm(temp1, temp2)

Take a look at Input handling in WinForm

I have posted my solution which uses the ProcessCmdKey and OnKeyPress events on the textbox. The comments show you how to use a Regex to verify the keypress and block/allow appropriately.
