Another option is to use the params keyword

public void DoSomething(params object[] theObjects)
{
  foreach(object o in theObjects)
  {
    // Something with the Objects…
  }
}

Called like...

DoSomething(this, that, theOther);

Write a function lensort to sort a list of strings based on length.

def lensort(a):
    n = len(a)
    for i in range(n):
        for j in range(i+1,n):
            if len(a[i]) > len(a[j]):
                temp = a[i]
                a[i] = a[j]
                a[j] = temp
    return a
print lensort(["hello","bye","good"])

Supposing you have a writable "uploads" folder in your application:

You can define a param like this:

Yii::$app->params['uploadPath'] = realpath(Yii::$app->basePath) . '/uploads/';

Then you can simply use the parameter as:

$path1 = Yii::$app->params['uploadPath'] . $filename;

Just depending on if you are using advanced or simple template the base path will be (following the link provided by phazei):

Simple @app: Your application root directory

Advanced @app: Your application root directory (either frontend or backend or console depending on where you access it from)

This way the application will be more portable than using realpath(dirname(__FILE__).'/../../'));

np.where returns a tuple of length equal to the dimension of the numpy ndarray on which it is called (in other words ndim) and each item of tuple is a numpy ndarray of indices of all those values in the initial ndarray for which the condition is True. (Please don't confuse dimension with shape)

For example:

x=np.arange(9).reshape(3,3)
print(x)
array([[0, 1, 2],
      [3, 4, 5],
      [6, 7, 8]])
y = np.where(x>4)
print(y)
array([1, 2, 2, 2], dtype=int64), array([2, 0, 1, 2], dtype=int64))

y is a tuple of length 2 because x.ndim is 2. The 1st item in tuple contains row numbers of all elements greater than 4 and the 2nd item contains column numbers of all items greater than 4. As you can see, [1,2,2,2] corresponds to row numbers of 5,6,7,8 and [2,0,1,2] corresponds to column numbers of 5,6,7,8 Note that the ndarray is traversed along first dimension(row-wise).

Similarly,

x=np.arange(27).reshape(3,3,3)
np.where(x>4)

will return a tuple of length 3 because x has 3 dimensions.

But wait, there's more to np.where!

when two additional arguments are added to np.where; it will do a replace operation for all those pairwise row-column combinations which are obtained by the above tuple.

x=np.arange(9).reshape(3,3)
y = np.where(x>4, 1, 0)
print(y)
array([[0, 0, 0],
   [0, 0, 1],
   [1, 1, 1]])

The easiest way to do this would be to put a link on your column headers, pointing to the same page. In the query string, put a variable so that you know what they clicked on, and then use ORDER BY in your SQL query to perform the ordering.

The HTML would look like this:

<th><a href="mypage.php?sort=type">Type:</a></th>
<th><a href="mypage.php?sort=desc">Description:</a></th>
<th><a href="mypage.php?sort=recorded">Recorded Date:</a></th>
<th><a href="mypage.php?sort=added">Added Date:</a></th>

And in the php code, do something like this:

<?php

$sql = "SELECT * FROM MyTable";

if ($_GET['sort'] == 'type')
{
    $sql .= " ORDER BY type";
}
elseif ($_GET['sort'] == 'desc')
{
    $sql .= " ORDER BY Description";
}
elseif ($_GET['sort'] == 'recorded')
{
    $sql .= " ORDER BY DateRecorded";
}
elseif($_GET['sort'] == 'added')
{
    $sql .= " ORDER BY DateAdded";
}

$>

Notice that you shouldn't take the $_GET value directly and append it to your query. As some user could got to MyPage.php?sort=; DELETE FROM MyTable;

Also using query builder

DB::table("rates")->get()->sum("rate_value")

To get summation of all rate value inside table rates.

To get summation of user products.

DB::table("users")->get()->sum("products")

To each his own but the right way to code this is to rename the columns inserting underscore so there are no gaps. This will ensure zero errors when coding. When printing the column names for public display you could search-and-replace to replace the underscore with a space.

Surprisingly there is no accepted answer. The issue only exists in 32-bit PHP.

From the documentation,

If the string does not contain any of the characters '.', 'e', or 'E' and the numeric value fits into integer type limits (as defined by PHP_INT_MAX), the string will be evaluated as an integer. In all other cases it will be evaluated as a float.

In other words, the $string is first interpreted as INT, which cause overflow (The $string value 2968789218 exceeds the maximum value (PHP_INT_MAX) of 32-bit PHP, which is 2147483647.), then evaluated to float by (float) or floatval().

Thus, the solution is:

$string = "2968789218";
echo 'Original: ' . floatval($string) . PHP_EOL;
$string.= ".0";
$float = floatval($string);
echo 'Corrected: ' . $float . PHP_EOL;

which outputs:

Original: 2.00
Corrected: 2968789218

To check whether your PHP is 32-bit or 64-bit, you can:

echo PHP_INT_MAX;

If your PHP is 64-bit, it will print out 9223372036854775807, otherwise it will print out 2147483647.

Inside the component put the input box in the following way.

<input className="class-name"
              type= "text"
              id="id-123"
              value={ this.state.value || "" }
              name="field-name"
              placeholder="Enter Name"
              />

I know many of the solutions mentioned above works, you can as well try flex.

But my image was rectangular and not fitting properly. so this is what i did.

.parentDivClass {
    position: relative;
    height: 100px;
    width: 100px;
    overflow: hidden;
    border-radius: 50%;
    margin: 20px;
    display: flex;
    justify-content: center;
}

and for the image inside, you can use,

child Img {
    display: block;
    margin: 0 auto;
    height: 100%;
    width: auto;
}

This is helpful when you are using bootstrap 4 classes.

The best way would be just to use a Makefile for your project and ST3 will automatically detect build system for your project. For example. If you press shift + ctrl/cmd +B you will see this:

http://vim.wikia.com/wiki/Search_and_replace

Try this search and replace:

:%s/foo/bar/gc

Change each 'foo' to 'bar', but ask for confirmation first.

Press y or n to change or keep your text.

One suggestion I'll make since no one yet has said it: PLEASE PLEASE PLEASE make a backup of your whole .xcodeproj file BEFORE you start modifying it's contents. Screwing up the project file and having no backup will lead to a very very unpleasant experience.

Being able to back out of an edit can be a godsend.

You can use stri_detect_fixed function from stringi package

        }
    }
}
else if (is_file($source) === true)
{
    $zip->addFromString(basename($source), file_get_contents($source));
}
$zip->close();

header('Content-Type: application/zip');
header('Content-disposition: attachment; filename='.$archive);
header('Content-Length: '.filesize($archive));
readfile($archive);
unlink($archive);
}

If Any Issue With the Code Let Me know.

The number in parentheses specifies the precision of fractional seconds to be stored. So, (0) would mean don't store any fraction of a second, and use only whole seconds. The default value if unspecified is 6 digits after the decimal separator.

So an unspecified value would store a date like:

TIMESTAMP 24-JAN-2012 08.00.05.993847 AM

And specifying (0) stores only:

TIMESTAMP(0) 24-JAN-2012 08.00.05 AM

See Oracle documentation on data types.

I pasted the contents of your example into a file named so.txt.

$ cat so.txt | awk '{ print $7 }' | cut -f2 -d"="
9
10

Explanation:

1. cat so.txt will print the contents of the file to stdout.
2. awk '{ print $7 }' will print the seventh column, i.e. the one containing id=n
3. cut -f2 -d"=" will cut the output of step #2 using = as the delimiter and get the second column (-f2)

If you'd rather get id= also, then:

$ cat so.txt | awk '{ print $7 }' 
id=9
id=10

Also, would I be right in concluding that a list comprehension is the most efficient way to do this?

Maybe. List comprehensions are not inherently computationally efficient. It is still running in linear time.

From my personal experience: I have significantly reduced computation time when dealing with large data sets by replacing list comprehensions (specifically nested ones) with for-loop/list-appending type structures you have above. In this application I doubt you will notice a difference.

I wouldn't push regular code into an exception block. Just check whether any rows exist that meet your condition, and proceed from there:

declare
  any_rows_found number;
begin
  select count(*)
  into   any_rows_found
  from   my_table
  where  rownum = 1 and
         ... other conditions ...

  if any_rows_found = 1 then
    ...
  else
    ...
  end if;

You can use the google docs OCR reader.

This will get your buttons and labels next to each other, at least. I believe the second part can't be done in css alone, and will need javascript. I found a page that might help you with that part as well, but I don't have time right now to try it out: http://www.webmasterworld.com/forum83/6942.htm

<style type="text/css">
.input input {
  float: left;
}
.input label {
  margin: 5px;
}
</style>
<div class="input radio">
    <fieldset>
        <legend>What color is the sky?</legend>
        <input type="hidden" name="data[Submit][question]" value="" id="SubmitQuestion" />

        <input type="radio" name="data[Submit][question]" id="SubmitQuestion1" value="1"  />
        <label for="SubmitQuestion1">A strange radient green.</label>

        <input type="radio" name="data[Submit][question]" id="SubmitQuestion2" value="2"  />
        <label for="SubmitQuestion2">A dark gloomy orange</label>
        <input type="radio" name="data[Submit][question]" id="SubmitQuestion3" value="3"  />
        <label for="SubmitQuestion3">A perfect glittering blue</label>
    </fieldset>
</div>

When you say the 'GUI Tool', I assume you're using Git For Windows.

IMPORTANT, I would highly recommend creating a new branch to do this on if you haven't already. That way your master can remain the same while you test out your changes.

With the GUI you need to 'roll back this commit' like you have with the history on the right of your view. Then you will notice you have all the unwanted files as changes to commit on the left. Now you need to right click on the grey title above all the uncommited files and select 'disregard changes'. This will set your files back to how they were in this version.

Use two single-quotes

SQL> SELECT 'D''COSTA' name FROM DUAL;

NAME
-------
D'COSTA

Alternatively, use the new (10g+) quoting method:

SQL> SELECT q'$D'COSTA$' NAME FROM DUAL;

NAME
-------
D'COSTA

You may just call the onBackPressed()and if you want some activity to display after the back button you have mention the

Intent intent = new Intent(ResetPinActivity.this, MenuActivity.class);
    startActivity(intent);
    finish();

that worked for me.

For multi-line shell scripts or those run multiple times, I would create a new bash script file (starting from #!/bin/bash), and simply run it with sh from Jenkinsfile:

sh 'chmod +x ./script.sh'
sh './script.sh'

It could be useful to change the encoding just on the command line before the file is read:

rem On MicroSoft Windows
vim --cmd "set encoding=utf-8" file.ext
# In *nix shell
vim --cmd 'set encoding=utf-8' file.ext

See starting, --cmd.

Use this

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("http://www.someplace.com");
ResponseHandler<String> resHandler = new BasicResponseHandler();
String page = httpClient.execute(httpGet, resHandler);

This can be used to grab the whole webpage as a string of html, i.e., "<html>...</html>"

If you use jqueryui (or another toolset) this is the way you do it

http://codepen.io/anon/pen/jeLhJ

html

<div id="hw" title="Empty the recycle bin?">The new way</div>

javascript

$('#hw').dialog({
    close:function(){
        alert('the old way')
    }
})

UPDATE : how to include jqueryui by pointing to cdn

<link rel="stylesheet" type="text/css" href="http://code.jquery.com/ui/1.10.0/themes/base/jquery-ui.css">
<script src="http://code.jquery.com/jquery-1.9.0.js"></script>
<script src="http://code.jquery.com/ui/1.10.0/jquery-ui.js"></script>

From the official angular documentation

// Simple GET request example :
$http.get('/someUrl').
  success(function(data, status, headers, config) {
    // this callback will be called asynchronously
    // when the response is available
  }).
  error(function(data, status, headers, config) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
  });

As you can see first parameter for error callback is data an status is second.

Michael Krelin's answer is close is not entirely safe, since it can be wrong in rare situations. The problem is that intervals in PostgreSQL do not have context with regards to things like daylight savings. Intervals store things internally as months, days, and seconds. Months aren't an issue in this case since subtracting two timestamps just use days and seconds but 'days' can be a problem.

If your subtraction involves daylight savings change-overs, a particular day might be considered 23 or 25 hours respectively. The interval will take that into account, which is useful for knowing the amount of days that passed in the symbolic sense but it would give an incorrect number of the actual hours that passed. Epoch on the interval will just multiply all days by 24 hours.

For example, if a full 'short' day passes and an additional hour of the next day, the interval will be recorded as one day and one hour. Which converted to epoch/3600 is 25 hours. But in reality 23 hours + 1 hour should be a total of 24 hours.

So the safer method is:

(EXTRACT(EPOCH FROM current_timestamp) - EXTRACT(EPOCH FROM somedate))/3600

As Michael mentioned in his follow-up comment, you'll also probably want to use floor() or round() to get the result as an integer value.

Although the advice not to parse HTML via regexp is valid, here's a expression that does pretty much what you asked:

/
   \G                     # start where the last match left off
   (?>                    # begin non-backtracking expression
       .*?                # *anything* until...
       <[Aa]\b            # an anchor tag
    )??                   # but look ahead to see that the rest of the expression
                          #    does not match.
    \s+                   # at least one space
    ( \p{Alpha}           # Our first capture, starting with one alpha
      \p{Alnum}*          # followed by any number of alphanumeric characters
    )                     # end capture #1
    (?: \s* = \s*         # a group starting with a '=', possibly surrounded by spaces.
        (?: (['"])        # capture a single quote character
            (.*?)         # anything else
             \2           # which ever quote character we captured before
        |   ( [^>\s'"]+ ) # any number of non-( '>', space, quote ) chars
        )                 # end group
     )?                   # attribute value was optional
/msx;

"But wait," you might say. "What about *comments?!?!" Okay, then you can replace the . in the non-backtracking section with: (It also handles CDATA sections.)

(?:[^<]|<[^!]|<![^-\[]|<!\[(?!CDATA)|<!\[CDATA\[.*?\]\]>|<!--(?:[^-]|-[^-])*-->)

• Also if you wanted to run a substitution under Perl 5.10 (and I think PCRE), you can put \K right before the attribute name and not have to worry about capturing all the stuff you want to skip over.

You can use numpy's slicing, simply start:stop:step.

>>> xs
array([1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4])
>>> xs[1::4]
array([2, 2, 2])

This creates a view of the the original data, so it's constant time. It'll also reflect changes to the original array and keep the whole original array in memory:

>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2]         # O(1), constant time
>>> b[:] = 0           # modifying the view changes original array
>>> a                  # original array is modified
array([0, 2, 0, 4, 0])

so if either of the above things are a problem, you can make a copy explicitly:

>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2].copy()  # explicit copy, O(n)
>>> b[:] = 0           # modifying the copy
>>> a                  # original is intact
array([1, 2, 3, 4, 5])

This isn't constant time, but the result isn't tied to the original array. The copy also contiguous in memory, which can make some operations on it faster.

If you're dividing positive integers you can shift it up, do the division and then check the bit to the right of the real b0. In other words, 100/8 is 12.5 but would return 12. If you do (100<<1)/8, you can check b0 and then round up after you shift the result back down.

When cin gets input it can't use, it sets failbit:

int n;
cin >> n;
if(!cin) // or if(cin.fail())
{
    // user didn't input a number
    cin.clear(); // reset failbit
    cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n'); //skip bad input
    // next, request user reinput
}

When cin's failbit is set, use cin.clear() to reset the state of the stream, then cin.ignore() to expunge the remaining input, and then request that the user re-input. The stream will misbehave so long as the failure state is set and the stream contains bad input.

I can't comment, but in reference to: Angular 2 optional route parameter

an update for Angular 6:

import {map} from "rxjs/operators"

constructor(route: ActivatedRoute) {
  let paramId = route.params.pipe(map(p => p.id));

  if (paramId) {
    ...
  }
}

See https://angular.io/api/router/ActivatedRoute for additional information on Angular6 routing.

Here are my two cents.

I have multiple tomcat instances running on different ports for my cluster setup. I use the following command to check each processes running on different ports.

/sbin/fuser 8080/tcp

Replace the port number as per your need.

And to kill the process use -k in the above command.

• This is much faster than the ps -ef way or any other commands where you call a command and call another grep on top of it.
• Works well with multiple installations of tomcat ,Or any other server that uses a port as a matter of fact running on the same server.

The equivalent command on BSD operating systems is fstat

There is no need to have two functions within one element, you need just one that calls the other two!

HTML

<a href="#" onclick="my_func()" >click</a>

JavaScript

function my_func() {
    my_func_1();
    my_func_2();
}

You can use the StringUtils.join() method of Apache Commons Lang:

String join = StringUtils.join(joinList, "+");

You would use data validation for this. Click in the cell you want to have a multiple drop down > DATA > Validation > Criteria (List from a Range) - here you select form a list of items you want in the drop down. And .. you are good. I have included an example to reference.

You can move Application.java to a folder under the java.

File.Copy(file_name, destination_dir + file_name.Substring(source_dir.Length), true);

This line has the error because what the code expected is the directory name + file name, not the file name.

This is the correct one

File.Copy(source_dir + file_name, destination_dir + file_name.Substring(source_dir.Length), true);

This is a solution to find files in a directory:

files = Dir["/work/myfolder/**/*.txt"]

files.each do |file_name|
  if !File.directory? file_name
    puts file_name
    File.open(file_name) do |file|
      file.each_line do |line|
        if line =~ /banco1/
          puts "Found: #{line}"
        end
      end
    end
  end
end

We can also rely on custom properties (aka CSS variables) in order to manipulate pseudo-element. We can read in the specification that:

Custom properties are ordinary properties, so they can be declared on any element, are resolved with the normal inheritance and cascade rules, can be made conditional with @media and other conditional rules, can be used in HTML’s style attribute, can be read or set using the CSSOM, etc.

Considering this, the idea is to define the custom property within the element and the pseudo-element will simply inherit it; thus we can easily modify it.

1) Using inline style:

.box:before {
  content:var(--content,"I am a before element");
  color:var(--color, red);
  font-size:25px;
}

<div class="box"></div>
<div class="box" style="--color:blue;--content:'I am a blue element'"></div>
<div class="box" style="--color:black"></div>
<div class="box" style="--color:#f0f;--content:'another element'"></div>

2) Using CSS and classes

.box:before {
  content:var(--content,"I am a before element");
  color:var(--color, red);
  font-size:25px;
}

.blue {
  --color:blue;
  --content:'I am a blue element';
}
.black {
  --color:black;
}

<div class="box"></div>
<div class="box black" ></div>
<div class="box blue"></div>

3) Using javascript

document.querySelectorAll('.box')[0].style.setProperty("--color", "blue");
document.querySelectorAll('.box')[1].style.setProperty("--content", "'I am another element'");

.box:before {
  content:var(--content,"I am a before element");
  color:var(--color, red);
  font-size:25px;
}

<div class="box"></div>
<div class="box"></div>

4) Using jQuery

$('.box').eq(0).css("--color", "blue");
/* the css() function with custom properties works only with a jQuery vesion >= 3.x
   with older version we can use style attribute to set the value. Simply pay
   attention if you already have inline style defined! 
*/
$('.box').eq(1).attr("style","--color:#f0f");

.box:before {
  content:"I am a before element";
  color:var(--color, red);
  font-size:25px;
}

<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<div class="box"></div>
<div class="box"></div>
<div class="box"></div>

It can also be used with complex values:

.box {
  --c:"content";
  --b:linear-gradient(red,blue);
  --s:20px;
  --p:0 15px;
}

.box:before {
  content: var(--c);
  background:var(--b);
  color:#fff;
  font-size: calc(2 * var(--s) + 5px);
  padding:var(--p);
}

<div class="box"></div>

You may notice that I am considering the syntax var(--c,value) where value is the default value and also called the fallback value.

From the same specification we can read:

The value of a custom property can be substituted into the value of another property with the var() function. The syntax of var() is:

var() = var( <custom-property-name> [, <declaration-value> ]? )

The first argument to the function is the name of the custom property to be substituted. The second argument to the function, if provided, is a fallback value, which is used as the substitution value when the referenced custom property is invalid.

And later:

To substitute a var() in a property’s value:

1. If the custom property named by the first argument to the var() function is animation-tainted, and the var() function is being used in the animation property or one of its longhands, treat the custom property as having its initial value for the rest of this algorithm.
2. If the value of the custom property named by the first argument to the var() function is anything but the initial value, replace the var() function by the value of the corresponding custom property.
3. Otherwise, if the var() function has a fallback value as its second argument, replace the var() function by the fallback value. If there are any var() references in the fallback, substitute them as well.
4. Otherwise, the property containing the var() function is invalid at computed-value time.

If we don't set the custom property OR we set it to initial OR it contains an invalid value then the fallback value will be used. The use of initial can be helpful in case we want to reset a custom property to its default value.

How to store inherit value inside a CSS variable (aka custom property)?

CSS custom properties (variables) for box model

you can just do

select rownum, l.* from student  l where name like %ram%

this assigns the row number as the rows are fetched (so no guaranteed ordering of course).

if you wanted to order first do:

select rownum, l.*
  from (select * from student l where name like %ram% order by...) l;

Are you using platform.system?

 system()
        Returns the system/OS name, e.g. 'Linux', 'Windows' or 'Java'.

        An empty string is returned if the value cannot be determined.

If that isn't working, maybe try platform.win32_ver and if it doesn't raise an exception, you're on Windows; but I don't know if that's forward compatible to 64-bit, since it has 32 in the name.

win32_ver(release='', version='', csd='', ptype='')
        Get additional version information from the Windows Registry
        and return a tuple (version,csd,ptype) referring to version
        number, CSD level and OS type (multi/single
        processor).

But os.name is probably the way to go, as others have mentioned.

if sys.platform == 'win32':
#---------
if os.environ.get('OS','') == 'Windows_NT':
#---------
try: import win32api
#---------
# Emulation using _winreg (added in Python 2.0) and
# sys.getwindowsversion() (added in Python 2.3)
import _winreg
GetVersionEx = sys.getwindowsversion
#----------
def system():

    """ Returns the system/OS name, e.g. 'Linux', 'Windows' or 'Java'.    
        An empty string is returned if the value cannot be determined.   
    """
    return uname()[0]

Using non-lambda, query-syntax LINQ, you can do this:

var movies = from row in _db.Movies 
             orderby row.Category, row.Name
             select row;

[EDIT to address comment] To control the sort order, use the keywords ascending (which is the default and therefore not particularly useful) or descending, like so:

var movies = from row in _db.Movies 
             orderby row.Category descending, row.Name
             select row;

As pointed out before, the problem was that the files were not visible by the fpm container. However to share data among containers the recommended pattern is using data-only containers (as explained in this article).

Long story short: create a container that just holds your data, share it with a volume, and link this volume in your apps with volumes_from.

Using compose (1.6.2 in my machine), the docker-compose.yml file would read:

version: "2"
services:
  nginx:
    build:
      context: .
      dockerfile: nginx/Dockerfile
    ports:
      - "80:80"
    links:
      - fpm
    volumes_from:
      - data
  fpm:
    image: php:fpm
    volumes_from:
      - data
  data:
    build:
      context: .
      dockerfile: data/Dockerfile
    volumes:
      - /var/www/html

Note that data publishes a volume that is linked to the nginx and fpm services. Then the Dockerfile for the data service, that contains your source code:

FROM busybox

# content
ADD path/to/source /var/www/html

And the Dockerfile for nginx, that just replaces the default config:

FROM nginx

# config
ADD config/default.conf /etc/nginx/conf.d

For the sake of completion, here's the config file required for the example to work:

server {
    listen 0.0.0.0:80;

    root /var/www/html;

    location / {
        index index.php index.html;
    }

    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass fpm:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root/$fastcgi_script_name;
    }
}

which just tells nginx to use the shared volume as document root, and sets the right config for nginx to be able to communicate with the fpm container (i.e.: the right HOST:PORT, which is fpm:9000 thanks to the hostnames defined by compose, and the SCRIPT_FILENAME).

What about a solution where the header is based on a view array :

class myViewController: UIViewController {
    var header: [UILabel] = myStringArray.map { (thisTitle: String) -> UILabel in
        let headerView = UILabel()
            headerView.text = thisTitle
    return(headerView)
}

Next in the delegate :

extension myViewController: UITableViewDelegate {
    func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        return(header[section])
    }
}

Merge - HEAD branch will generate a new commit, preserving the ancestry of each commit history. History can become polluted if merge commits are made by multiple people who work on the same branch in parallel.

Rebase - Re-writes the changes of one branch onto another without creating a new commit. The code history is simplified, linear and readable but it doesn't work with pull requests, because you can't see what minor changes someone made.

I would use git merge when dealing with feature-based workflow or if I am not familiar with rebase. But, if I want a more a clean, linear history then git rebase is more appropriate. For more details be sure to check out this merge or rebase article.

Nope. That can't be done. The best 'way' of doing that is just making the expiration date be like 2100.

A simple solution:

List<Object> lst  =listOfTypeObject;   
ArrayList<String> aryLst = new ArrayList<String>();
    for (int i = 0; i < lst.size(); i++) {
        aryLst.add(lst.get(i).toString());
    }

Note: this works when the list contains all the elements of datatype String.

os.path.isfile("bob.txt") # Does bob.txt exist?  Is it a file, or a directory?
os.path.isdir("bob")

This Blog Post describes various styling aspects of EditText and AutoCompleteTextView wrapped by TextInputLayout.

For EditText and AppCompat lib 22.1.0+ you can set theme attribute with some theme related settings:

<style name="StyledTilEditTextTheme">
   <item name="android:imeOptions">actionNext</item>
   <item name="android:singleLine">true</item>
   <item name="colorControlNormal">@color/greyLight</item>
   <item name="colorControlActivated">@color/blue</item>
   <item name="android:textColorPrimary">@color/blue</item>
   <item name="android:textSize">@dimen/styledtil_edit_text_size</item>
</style>

<style name="StyledTilEditText">
    <item name="android:theme">@style/StyledTilEditTextTheme</item>
    <item name="android:paddingTop">4dp</item>
</style>

and apply them on EditText:

<EditText
    android:id="@+id/etEditText"
    style="@style/StyledTilEditText"

For AutoCompleteTextView things are more complicated because wrapping it in TextInputLayout and applying this theme breaks floating label behaviour. You need to fix this in code:

private void setStyleForTextForAutoComplete(int color) {
    Drawable wrappedDrawable =     DrawableCompat.wrap(autoCompleteTextView.getBackground());
    DrawableCompat.setTint(wrappedDrawable, color);
    autoCompleteTextView.setBackgroundDrawable(wrappedDrawable);
}

and in Activity.onCreate:

setStyleForTextForAutoComplete(getResources().getColor(R.color.greyLight));
autoCompleteTextView.setOnFocusChangeListener((v, hasFocus) -> {
    if(hasFocus) {
        setStyleForTextForAutoComplete(getResources().getColor(R.color.blue));
    } else {
        if(autoCompleteTextView.getText().length() == 0) {  
              setStyleForTextForAutoComplete(getResources().getColor(R.color.greyLight));
        }
    }
});

Some browsers support Array.indexOf().

If not, you could augment the Array object via its prototype like so...

if (!Array.prototype.indexOf)
{
  Array.prototype.indexOf = function(searchElement /*, fromIndex */)
  {
    "use strict";

    if (this === void 0 || this === null)
      throw new TypeError();

    var t = Object(this);
    var len = t.length >>> 0;
    if (len === 0)
      return -1;

    var n = 0;
    if (arguments.length > 0)
    {
      n = Number(arguments[1]);
      if (n !== n) // shortcut for verifying if it's NaN
        n = 0;
      else if (n !== 0 && n !== (1 / 0) && n !== -(1 / 0))
        n = (n > 0 || -1) * Math.floor(Math.abs(n));
    }

    if (n >= len)
      return -1;

    var k = n >= 0
          ? n
          : Math.max(len - Math.abs(n), 0);

    for (; k < len; k++)
    {
      if (k in t && t[k] === searchElement)
        return k;
    }
    return -1;
  };
}

A hashmap works like this (this is a little bit simplified, but it illustrates the basic mechanism):

It has a number of "buckets" which it uses to store key-value pairs in. Each bucket has a unique number - that's what identifies the bucket. When you put a key-value pair into the map, the hashmap will look at the hash code of the key, and store the pair in the bucket of which the identifier is the hash code of the key. For example: The hash code of the key is 235 -> the pair is stored in bucket number 235. (Note that one bucket can store more then one key-value pair).

When you lookup a value in the hashmap, by giving it a key, it will first look at the hash code of the key that you gave. The hashmap will then look into the corresponding bucket, and then it will compare the key that you gave with the keys of all pairs in the bucket, by comparing them with equals().

Now you can see how this is very efficient for looking up key-value pairs in a map: by the hash code of the key the hashmap immediately knows in which bucket to look, so that it only has to test against what's in that bucket.

Looking at the above mechanism, you can also see what requirements are necessary on the hashCode() and equals() methods of keys:

• If two keys are the same (equals() returns true when you compare them), their hashCode() method must return the same number. If keys violate this, then keys that are equal might be stored in different buckets, and the hashmap would not be able to find key-value pairs (because it's going to look in the same bucket).

• If two keys are different, then it doesn't matter if their hash codes are the same or not. They will be stored in the same bucket if their hash codes are the same, and in this case, the hashmap will use equals() to tell them apart.

The best way is to use math.
I knew this from school.(kinda also from codewars)

def digital_sum(num):
    return (num % 9) or num and 9

Just don't know how this works in code, but I know it's maths

If a number is divisible by 9 then, it's digital_sum will be 9,
if that's not the case then num % 9 will be the digital sum.

<h1><span style="font-weight:bold;">THIS IS</span> A HEADLINE</h1>

But be sure that h1 is marked with

font-weight:normal;

You can also set the style with a id or class attribute.

The result is same for all options. Redirect.

<meta> in HTML:

• Show content of your site, and next redirect user after a few (or 0) seconds.
• Don't need JavaScript enabled.
• Don't need PHP.

window.location in JS:

• Javascript enabled needed.
• Don't need PHP.
• Show content of your site, and next redirect user after a few (or 0) seconds.
• Redirect can be dependent on any conditions if (1 === 1) { window.location.href = 'http://example.com'; }.

header('Location:') in PHP:

• Don't need JavaScript enabled.
• PHP needed.
• Redirect will be executed first, user never see what is after. header() must be the first command in php script, before output any other. If you try output some before header, will receive an Warning: Cannot modify header information - headers already sent

Once you have your Context and know the name of the database, use:

context.deleteDatabase(DATABASE_NAME);

When this line gets run, the database should be deleted.

In PySpark(python) one of the option is to have the column in unix_timestamp format.We can convert string to unix_timestamp and specify the format as shown below. Note we need to import unix_timestamp and lit function

from pyspark.sql.functions import unix_timestamp, lit

df.withColumn("tx_date", to_date(unix_timestamp(df_cast["date"], "MM/dd/yyyy").cast("timestamp")))

Now we can apply the filters

df_cast.filter(df_cast["tx_date"] >= lit('2017-01-01')) \
       .filter(df_cast["tx_date"] <= lit('2017-01-31')).show()

Use ScriptEngine.eval(java.io.Reader) to read the script

ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("JavaScript");
// read script file
engine.eval(Files.newBufferedReader(Paths.get("C:/Scripts/Jsfunctions.js"), StandardCharsets.UTF_8));

Invocable inv = (Invocable) engine;
// call function from script file
inv.invokeFunction("yourFunction", "param");

Deleting all instances of *.exd resolved it for me.

I'd use a regexp :

>>> import re
>>> re.findall(r'\d+', 'hello 42 I\'m a 32 string 30')
['42', '32', '30']

This would also match 42 from bla42bla. If you only want numbers delimited by word boundaries (space, period, comma), you can use \b :

>>> re.findall(r'\b\d+\b', 'he33llo 42 I\'m a 32 string 30')
['42', '32', '30']

To end up with a list of numbers instead of a list of strings:

>>> [int(s) for s in re.findall(r'\b\d+\b', 'he33llo 42 I\'m a 32 string 30')]
[42, 32, 30]

From Java8:

import java.time.Instant;
import java.util.Date;

Date date = Date.from(Instant.parse("2000-01-01T00:00:00.000Z"))

In the context of data storage, serialization (or serialisation) is the process of translating data structures or object state into a format that can be stored (for example, in a file or memory buffer) or transmitted (for example, across a network connection link) and reconstructed later. [...]
The opposite operation, extracting a data structure from a series of bytes, is deserialization. From Wikipedia

In Python "serialization" does nothing else than just converting the given data structure (e.g. a dict) into its valid JSON pendant (object).

• Python's True will be converted to JSONs true and the dictionary itself will then be encapsulated in quotes.
• You can easily spot the difference between a Python dictionary and JSON by their Boolean values:
  • Python: True / False,
  • JSON: true / false
• Python builtin module json is the standard way to do serialization:

Code example:

data = {
    "president": {
        "name": "Zaphod Beeblebrox",
        "species": "Betelgeusian",
        "male": True,
    }
}

import json
json_data = json.dumps(data, indent=2) # serialize
restored_data = json.loads(json_data) # deserialize

# serialized json_data now looks like:
# {
#   "president": {
#     "name": "Zaphod Beeblebrox",
#     "species": "Betelgeusian",
#     "male": true
#   }
# }

If you need to update the value in a particular table:

UPDATE TABLE-NAME SET COLUMN-NAME = REPLACE(TABLE-NAME.COLUMN-NAME, 'STRING-TO-REPLACE', 'REPLACEMENT-STRING');

where

  TABLE-NAME         - The name of the table being updated
  COLUMN-NAME        - The name of the column being updated
  STRING-TO-REPLACE  - The value to replace
  REPLACEMENT-STRING - The replacement

I don't think you properly understood what you read. If it gets compiled to the correct type, then there is no difference. When I do this:

var i = 42;

The compiler knows it's an int, and generate code as if I had written

int i = 42;

As the post you linked to says, it gets compiled to the same type. It's not a runtime check or anything else requiring extra code. The compiler just figures out what the type must be, and uses that.

Actually, you CAN get the whole Bitcoin trades history from Bitcoincharts in CSV format here : http://api.bitcoincharts.com/v1/csv/

it is updated twice a day for active exchanges, and there is a few dead exchanges, too.

EDIT: Since there are no column headers in the CSVs, here's what they are : column 1) the trade's timestamp, column 2) the price, column 3) the volume of the trade

Problem was solved by myself using tutorial of weheartswift

You have mentioned "user" twice in your FROM clause. You must provide a table alias to at least one mention so each mention of user. can be pinned to one or the other instance:

FROM article INNER JOIN section
ON article.section_id = section.id
INNER JOIN category ON article.category_id = category.id
INNER JOIN user **AS user1** ON article.author\_id = **user1**.id
LEFT JOIN user **AS user2** ON article.modified\_by = **user2**.id
WHERE article.id = '1'

(You may need something different - I guessed which user is which, but the SQL engine won't guess.)

Also, maybe you only needed one "user". Who knows?

You need to use regular expressions to identify the unwanted characters. For the most easily readable code, you want the str_replace_all from the stringr package, though gsub from base R works just as well.

The exact regular expression depends upon what you are trying to do. You could just remove those specific characters that you gave in the question, but it's much easier to remove all punctuation characters.

x <- "a1~!@#$%^&*(){}_+:\"<>?,./;'[]-=" #or whatever
str_replace_all(x, "[[:punct:]]", " ")

(The base R equivalent is gsub("[[:punct:]]", " ", x).)

An alternative is to swap out all non-alphanumeric characters.

str_replace_all(x, "[^[:alnum:]]", " ")

Note that the definition of what constitutes a letter or a number or a punctuatution mark varies slightly depending upon your locale, so you may need to experiment a little to get exactly what you want.

Here's a function that finds the dictionary's index position if it exists.

dicts = [{'id':'1234','name':'Jason'},
         {'id':'2345','name':'Tom'},
         {'id':'3456','name':'Art'}]

def find_index(dicts, key, value):
    class Null: pass
    for i, d in enumerate(dicts):
        if d.get(key, Null) == value:
            return i
    else:
        raise ValueError('no dict with the key and value combination found')

print find_index(dicts, 'name', 'Tom')
# 1
find_index(dicts, 'name', 'Ensnare')
# ValueError: no dict with the key and value combination found

Swing + SwingX + Miglayout is my combination of choice. Miglayout is so much simpler than Swings perceived 200 different layout managers and much more powerful. Also, it provides you with the ability to "debug" your layouts, which is especially handy when creating complex layouts.

Looks like the path you gave doesn't have any bootstrap files in them.

href="~/lib/bootstrap/dist/css/bootstrap.min.css"

Make sure the files exist over there , else point the files to the correct path, which should be in your case

href="~/node_modules/bootstrap/dist/css/bootstrap.min.css"

Here is a query which you can use to search for anything in from your database as a search result ,

SELECT * FROM tbl_customer 
    WHERE CustomerName LIKE '%".$search."%'
    OR Address LIKE '%".$search."%' 
    OR City LIKE '%".$search."%' 
    OR PostalCode LIKE '%".$search."%' 
    OR Country LIKE '%".$search."%'

Using this code will help you search in for multiple columns easily

This problem was solved by following steps -

1. Go to the local m2 repository and find the directory org/apache/maven/plugins/maven-surefire-plugin.
2. Delete the problematic version.
3. maven update the project, then download it again.

It's your "fault" in that that's how Or is defined, so it's the behaviour you should expect:

In a Boolean comparison, the Or operator always evaluates both expressions, which could include making procedure calls. The OrElse Operator (Visual Basic) performs short-circuiting, which means that if expression1 is True, then expression2 is not evaluated.

But you don't have to endure it. You can use OrElse to get short-circuiting behaviour.

So you probably want:

If (example Is Nothing OrElse Not example.Item = compare.Item) Then
    'Proceed
End If

I can't say it reads terribly nicely, but it should work...

You can use the test command:

test -d $(OBJDIR) || mkdir $(OBJDIR)

Internet Explorer doesn't fully support Flexbox due to:

Partial support is due to large amount of bugs present (see known issues).

_{Screenshot and infos taken from caniuse.com}

Notes

Internet Explorer before 10 doesn't support Flexbox, while IE 11 only supports the 2012 syntax.

Known issues

• IE 11 requires a unit to be added to the third argument, the flex-basis property see MSFT documentation.
• In IE10 and IE11, containers with display: flex and flex-direction: column will not properly calculate their flexed childrens' sizes if the container has min-height but no explicit height property. See bug.
• In IE10 the default value for flex is 0 0 auto rather than 0 1 auto as defined in the latest spec.
• IE 11 does not vertically align items correctly when min-height is used. See bug.

Workarounds

Flexbugs is a community-curated list of Flexbox issues and cross-browser workarounds for them. Here's a list of all the bugs with a workaround available and the browsers that affect.

1. Minimum content sizing of flex items not honored
2. Column flex items set to align-items: center overflow their container
3. min-height on a flex container won't apply to its flex items
4. flex shorthand declarations with unitless flex-basis values are ignored
5. Column flex items don't always preserve intrinsic aspect ratios
6. The default flex value has changed
7. flex-basis doesn't account for box-sizing: border-box
8. flex-basis doesn't support calc()
9. Some HTML elements can't be flex containers
10. align-items: baseline doesn't work with nested flex containers
11. Min and max size declarations are ignored when wrapping flex items
12. Inline elements are not treated as flex-items
13. Importance is ignored on flex-basis when using flex shorthand
14. Shrink-to-fit containers with flex-flow: column wrap do not contain their items
15. Column flex items ignore margin: auto on the cross axis
16. flex-basis cannot be animated
17. Flex items are not correctly justified when max-width is used

I think that the fastest way to do this is to just clone the node, which will remove all event listeners:

var old_element = document.getElementById("btn");
var new_element = old_element.cloneNode(true);
old_element.parentNode.replaceChild(new_element, old_element);

Just be careful, as this will also clear event listeners on all child elements of the node in question, so if you want to preserve that you'll have to resort to explicitly removing listeners one at a time.

As far as I know you can only join this way:

var query = from obj_i in set1
join obj_j in set2 on 
    new { 
      JoinProperty1 = obj_i.SomeField1,
      JoinProperty2 = obj_i.SomeField2,
      JoinProperty3 = obj_i.SomeField3,
      JoinProperty4 = obj_i.SomeField4
    } 
    equals 
    new { 
      JoinProperty1 = obj_j.SomeOtherField1,
      JoinProperty2 = obj_j.SomeOtherField2,
      JoinProperty3 = obj_j.SomeOtherField3,
      JoinProperty4 = obj_j.SomeOtherField4
    }

The main requirements are: Property names, types and order in the anonymous objects you're joining on must match.

You CAN'T use ANDs, ORs, etc. in joins. Just object1 equals object2.

class c1 
    {
    public int someIntField;
    public string someStringField;

class c2

    public Int64 someInt64Property {get;set;}
    private object someField;
    public string someStringFunction(){return someField.ToString();}
    }
    
void Main()
{
    var set1 = new List<c1>();
    var set2 = new List<c2>();
    
    var query = from obj_i in set1
    join obj_j in set2 on 
        new { 
                JoinProperty1 = (Int64) obj_i.someIntField,
                JoinProperty2 = obj_i.someStringField
            } 
        equals 
        new { 
                JoinProperty1 = obj_j.someInt64Property,
                JoinProperty2 = obj_j.someStringFunction()
            }
    select new {obj1 = obj_i, obj2 = obj_j};
}

Addressing names and property order is straightforward, addressing types can be achieved via casting/converting/parsing/calling methods etc. This might not always work with LINQ to EF or SQL or NHibernate, most method calls definitely won't work and will fail at run-time, so YMMV (Your Mileage May Vary). This is because they are copied to public read-only properties in the anonymous objects, so as long as your expression produces values of correct type the join property - you should be fine.

To dynamically change the color of a text box goto properties, goto font/Color and set the following expression

=SWITCH(Fields!CurrentRiskLevel.Value = "Low", "Green",
Fields!CurrentRiskLevel.Value = "Moderate", "Blue",
Fields!CurrentRiskLevel.Value = "Medium", "Yellow",
Fields!CurrentRiskLevel.Value = "High", "Orange",
Fields!CurrentRiskLevel.Value = "Very High", "Red"
)

Same way for tolerance

=SWITCH(Fields!Tolerance.Value = "Low", "Red",
Fields!Tolerance.Value = "Moderate", "Orange",
Fields!Tolerance.Value = "Medium", "Yellow",
Fields!Tolerance.Value = "High", "Blue",
Fields!Tolerance.Value = "Very High", "Green")

NSURL.h provided - (BOOL)checkResourceIsReachableAndReturnError:(NSError **)error to do so

NSURL *fileURL = [NSURL fileURLWithPath:NSHomeDirectory()];
NSError * __autoreleasing error = nil;
if ([fileURL checkResourceIsReachableAndReturnError:&error]) {
    NSLog(@"%@ exists", fileURL);
} else {
    NSLog(@"%@ existence checking error: %@", fileURL, error);
}

Or using Swift

if let url = URL(fileURLWithPath: NSHomeDirectory()) {
    do {
        let result = try url.checkResourceIsReachable()
    } catch {
        print(error)
    }
}

For this problem, as for many others involving non-trivial left joins such as left-joining on inner-joined tables, I find it convenient and somewhat more readable to split the query with a with clause. In your example,

with settings_for_char as (
  select setting_id, value from character_settings where character_id = 1
)
select
  settings.*,
  settings_for_char.value
from
  settings
  left join settings_for_char on settings_for_char.setting_id = settings.id;

[HttpPost] // it use when you write logic on button click event

public ActionResult DemoInsert(EmployeeModel emp)
{
    Employee emptbl = new Employee();    // make object of table
    emptbl.EmpName = emp.EmpName;
    emptbl.EmpAddress = emp.EmpAddress;  // add if any field you want insert
    dbc.Employees.Add(emptbl);           // pass the table object 
    dbc.SaveChanges();

    return View();
}

For example :

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

here.

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

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

you can refer here for CSS

hope this helps.

There is another simple and elegant option:

parameters.OfType<EmailParameterClass>();

This will remove all elements that are not of type EmailParameterClass which will obviously filter out any elements of type null.

Here's a test:

class Test { }
class Program
{
    static void Main(string[] args)
    {
        var list = new List<Test>();
        list.Add(null);
        Console.WriteLine(list.OfType<Test>().Count());// 0
        list.Add(new Test());
        Console.WriteLine(list.OfType<Test>().Count());// 1
        Test test = null;
        list.Add(test);
        Console.WriteLine(list.OfType<Test>().Count());// 1
        Console.ReadKey();
    }
}

You have enabled CORS and enabled Access-Control-Allow-Origin : * in the server.If still you get GET method working and POST method is not working then it might be because of the problem of Content-Type and data problem.

First AngularJS transmits data using Content-Type: application/json which is not serialized natively by some of the web servers (notably PHP). For them we have to transmit the data as Content-Type: x-www-form-urlencoded

Example :-

        $scope.formLoginPost = function () {
            $http({
                url: url,
                method: "POST",
                data: $.param({ 'username': $scope.username, 'Password': $scope.Password }),
                headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
            }).then(function (response) {
                // success
                console.log('success');
                console.log("then : " + JSON.stringify(response));
            }, function (response) { // optional
                // failed
                console.log('failed');
                console.log(JSON.stringify(response));
            });
        };

Note : I am using $.params to serialize the data to use Content-Type: x-www-form-urlencoded. Alternatively you can use the following javascript function

function params(obj){
    var str = "";
    for (var key in obj) {
        if (str != "") {
            str += "&";
        }
        str += key + "=" + encodeURIComponent(obj[key]);
    }
    return str;
}

and use params({ 'username': $scope.username, 'Password': $scope.Password }) to serialize it as the Content-Type: x-www-form-urlencoded requests only gets the POST data in username=john&Password=12345 form.

It's OK to run Docker-in-Docker (DinD) and in fact Docker (the company) has an official DinD image for this.

The caveat however is that it requires a privileged container, which depending on your security needs may not be a viable alternative.

The alternative solution of running Docker using sibling containers (aka Docker-out-of-Docker or DooD) does not require a privileged container, but has a few drawbacks that stem from the fact that you are launching the container from within a context that is different from that one in which it's running (i.e., you launch the container from within a container, yet it's running at the host's level, not inside the container).

I wrote a blog describing the pros/cons of DinD vs DooD here.

Having said this, Nestybox (a startup I just founded) is working on a solution that runs true Docker-in-Docker securely (without using privileged containers). You can check it out at www.nestybox.com.

Use set -u which will cause any unset argument reference to immediately fail the script.

Please, see the article: Writing Robust Bash Shell Scripts - David Pashley.com.

SELECT * FROM Table_Name LIMIT 5;

An equivalent alternative to "set -e" is

set -o errexit

It makes the meaning of the flag somewhat clearer than just "-e".

Random addition: to temporarily disable the flag, and return to the default (of continuing execution regardless of exit codes), just use

set +e
echo "commands run here returning non-zero exit codes will not cause the entire script to fail"
echo "false returns 1 as an exit code"
false
set -e

This precludes proper error handling mentioned in other responses, but is quick & effective (just like bash).

It's perfectly possible to update multiple columns in the same statement, and in fact your code is doing it. So why does it seem that "INV_TOTAL is not updating, only the inv_discount"?

Because you're updating INV_TOTAL with INV_DISCOUNT, and the database is going to use the existing value of INV_DISCOUNT and not the one you change it to. So I'm afraid what you need to do is this:

UPDATE INVOICE
   SET INV_DISCOUNT = DISC1 * INV_SUBTOTAL
     , INV_TOTAL    = INV_SUBTOTAL - (DISC1 * INV_SUBTOTAL)     
WHERE INV_ID = I_INV_ID;

        

Perhaps that seems a bit clunky to you. It is, but the problem lies in your data model. Storing derivable values in the table, rather than deriving when needed, rarely leads to elegant SQL.

If you are using AngularJS, and you are using Angular Bootstrap : https://angular-ui.github.io/bootstrap/

You can do this so nice like this :

HTML:

<nav id="header-navbar" class="navbar navbar-default" ng-class="{'navbar-fixed-top':scrollDown}" role="navigation" scroll-nav>
    <div class="container-fluid top-header">
        <!--- Rest of code --->
    </div>
</nav>

CSS: (Note here I use padding as bigger nav to shrink without padding you can modify as you want)

nav.navbar {
  -webkit-transition: all 0.4s ease;
  transition: all 0.4s ease;

  background-color: white;
  margin-bottom: 0;
  padding: 25px;
}

.navbar-fixed-top {
  padding: 0;
}

And then add your directive

Directive: (Note you may need to change this.pageYOffset >= 50 from 50 to more or less to fulfill your needs)

angular.module('app')
.directive('scrollNav', function ($window) {
  return function(scope, element, attrs) {
    angular.element($window).bind("scroll", function() {
      if (this.pageYOffset >= 50) {
        scope.scrollDown = true;
      } else {
        scope.scrollDown = false;
      }
      scope.$apply();
    });
  };
});

This will do the job nicely, animated and cool way.

Prevent user to enter space in textbox in Angular 6

<input type="text" (keydown.space)="$event.preventDefault();" required />

I think the correct method should be : - (void)addTarget:(id)target action:(SEL)action forControlEvents:(UIControlEvents)controlEvents

UIControl Reference

Where do you get your method from?

I see that your selector has an argument, that argument will be filled by the runtime system. It will send you back the button through that argument.

Your method should look like:

- (void)buttonPressed:(id)BUTTON_HERE { }

It looks like even thou here is so much answers no one was sufficient for me. I wanted to force orientation and then on going back go back to device orientation but [UIViewController attemptRotationToDeviceOrientation]; just did'nt work. What also did complicated whole thing is that I added shouldAutorotate to false based on some answer and could not get desired effects to rotate back correctly in all scenarios.

So this is what I did:

Before pushing of controller in call in his init constructor this:

_userOrientation = UIDevice.currentDevice.orientation;
[UIDevice.currentDevice setValue:@(UIInterfaceOrientationPortrait) forKey:@"orientation"];
[self addNotificationCenterObserver:@selector(rotated:)
                               name:UIDeviceOrientationDidChangeNotification];

So I save last device orientation and register for orientation change event. Orientation change event is simple:

- (void)rotated:(NSNotification*)notification {
    _userOrientation = UIDevice.currentDevice.orientation;
}

And on view dissmising I just force back to any orientation I have as userOreintation:

- (void)onViewDismissing {
    super.onViewDismissing;
    [UIDevice.currentDevice setValue:@(_userOrientation) forKey:@"orientation"];
    [UIViewController attemptRotationToDeviceOrientation];
}

And this has to be there too:

- (BOOL)shouldAutorotate {
    return true;
}

- (UIInterfaceOrientationMask)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}

And also navigation controller has to delegate to shouldAutorotate and supportedInterfaceOrientations, but that most people already have I believe.

PS: Sorry I use some extensions and base classes but names are quite meaningful so concept is understandable, will make even more extensions because it's not too much pretty now.

As you keep getting pages of results I'm assuming you started the session in SQL*Plus. If so, the easy thing to do is to bash ctrl + break many, many times until it stops.

The more complicated and the more generic way(s) I detail below in order of increasing ferocity / evil. The first one will probably work for you but if it doesn't you can keep moving down the list.

Most of these are not recommended and can have unintended consequences.

1. Oracle level - Kill the process in the database

As per ObiWanKenobi's answer and the ALTER SESSION documentation

alter system kill session 'sid,serial#';

To find the sid, session id, and the serial#, serial number, run the following query - summarised from OracleBase - and find your session:

select s.sid, s.serial#, p.spid, s.username, s.schemaname
     , s.program, s.terminal, s.osuser
  from v$session s
  join v$process p
    on s.paddr = p.addr
 where s.type != 'BACKGROUND'

If you're running a RAC then you need to change this slightly to take into account the multiple instances, inst_id is what identifies them:

select s.inst_id, s.sid, s.serial#, p.spid, s.username
     , s.schemaname, s.program, s.terminal, s.osuser
  from Gv$session s
  join Gv$process p
    on s.paddr = p.addr
   and s.inst_id = p.inst_id
 where s.type != 'BACKGROUND'

This query would also work if you're not running a RAC.

If you're using a tool like PL/SQL Developer then the sessions window will also help you find it.

For a slightly stronger "kill" you can specify the IMMEDIATE keyword, which instructs the database to not wait for the transaction to complete:

alter system kill session 'sid,serial#' immediate;

2. OS level - Issue a SIGTERM

kill pid

This assumes you're using Linux or another *nix variant. A SIGTERM is a terminate signal from the operating system to the specific process asking it to stop running. It tries to let the process terminate gracefully.

Getting this wrong could result in you terminating essential OS processes so be careful when typing.

You can find the pid, process id, by running the following query, which'll also tell you useful information like the terminal the process is running from and the username that's running it so you can ensure you pick the correct one.

select p.*
  from v$process p
  left outer join v$session s
    on p.addr = s.paddr
 where s.sid = ?
   and s.serial# = ?

Once again, if you're running a RAC you need to change this slightly to:

select p.*
  from Gv$process p
  left outer join Gv$session s
    on p.addr = s.paddr
 where s.sid = ?
   and s.serial# = ?

Changing the where clause to where s.status = 'KILLED' will help you find already killed process that are still "running".

3. OS - Issue a SIGKILL

kill -9 pid

Using the same pid you picked up in 2, a SIGKILL is a signal from the operating system to a specific process that causes the process to terminate immediately. Once again be careful when typing.

This should rarely be necessary. If you were doing DML or DDL it will stop any rollback being processed and may make it difficult to recover the database to a consistent state in the event of failure.

All the remaining options will kill all sessions and result in your database - and in the case of 6 and 7 server as well - becoming unavailable. They should only be used if absolutely necessary...

4. Oracle - Shutdown the database

shutdown immediate

This is actually politer than a SIGKILL, though obviously it acts on all processes in the database rather than your specific process. It's always good to be polite to your database.

Shutting down the database should only be done with the consent of your DBA, if you have one. It's nice to tell the people who use the database as well.

It closes the database, terminating all sessions and does a rollback on all uncommitted transactions. It can take a while if you have large uncommitted transactions that need to be rolled back.

5. Oracle - Shutdown the database ( the less nice way )

shutdown abort

This is approximately the same as a SIGKILL, though once again on all processes in the database. It's a signal to the database to stop everything immediately and die - a hard crash. It terminates all sessions and does no rollback; because of this it can mean that the database takes longer to startup again. Despite the incendiary language a shutdown abort isn't pure evil and can normally be used safely.

As before inform people the relevant people first.

6. OS - Reboot the server

reboot

Obviously, this not only stops the database but the server as well so use with caution and with the consent of your sysadmins in addition to the DBAs, developers, clients and users.

7. OS - The last stage

I've had reboot not work... Once you've reached this stage you better hope you're using a VM. We ended up deleting it...

Simply :

JVM is the virtual machine Java code executes on

JRE is the environment (standard libraries and JVM) required to run Java applications

JDK is the JRE with developer tools and documentation

First of all, I don't really see why you would want an object having only ID and Version, and all other props to be nulls. However, here is some code which will do that for you (which doesn't use JPA Em, but normal Hibernate. I assume you can find the equivalence in JPA or simply obtain the Hibernate Session obj from the em delegate Accessing Hibernate Session from EJB using EntityManager ):

List<T> results = session.createCriteria(entityClazz)
    .setProjection( Projections.projectionList()
        .add( Property.forName("ID") )
        .add( Property.forName("VERSION") )
    )
    .setResultTransformer(Transformers.aliasToBean(entityClazz); 
    .list();

This will return a list of Objects having their ID and Version set and all other props to null, as the aliasToBean transformer won't be able to find them. Again, I am uncertain I can think of a situation where I would want to do that.

Ted Hopp answered this quite nicely. I have been using res/raw for my opengl texture and shader files. I was thinking about moving them to an assets directory to provide a hierarchical organization.

This thread convinced me not to. First, because I like the use of a unique resource id. Second because it's very simple to use InputStream/openRawResource or BitmapFactory to read in the file. Third because it's very useful to be able to use in a portable library.

TLDR Summary

In modern MongoDB releases you can brute force this with $slice just off the basic aggregation result. For "large" results, run parallel queries instead for each grouping ( a demonstration listing is at the end of the answer ), or wait for SERVER-9377 to resolve, which would allow a "limit" to the number of items to $push to an array.

db.books.aggregate([
    { "$group": {
        "_id": {
            "addr": "$addr",
            "book": "$book"
        },
        "bookCount": { "$sum": 1 }
    }},
    { "$group": {
        "_id": "$_id.addr",
        "books": { 
            "$push": { 
                "book": "$_id.book",
                "count": "$bookCount"
            },
        },
        "count": { "$sum": "$bookCount" }
    }},
    { "$sort": { "count": -1 } },
    { "$limit": 2 },
    { "$project": {
        "books": { "$slice": [ "$books", 2 ] },
        "count": 1
    }}
])

MongoDB 3.6 Preview

Still not resolving SERVER-9377, but in this release $lookup allows a new "non-correlated" option which takes an "pipeline" expression as an argument instead of the "localFields" and "foreignFields" options. This then allows a "self-join" with another pipeline expression, in which we can apply $limit in order to return the "top-n" results.

db.books.aggregate([
  { "$group": {
    "_id": "$addr",
    "count": { "$sum": 1 }
  }},
  { "$sort": { "count": -1 } },
  { "$limit": 2 },
  { "$lookup": {
    "from": "books",
    "let": {
      "addr": "$_id"
    },
    "pipeline": [
      { "$match": { 
        "$expr": { "$eq": [ "$addr", "$$addr"] }
      }},
      { "$group": {
        "_id": "$book",
        "count": { "$sum": 1 }
      }},
      { "$sort": { "count": -1  } },
      { "$limit": 2 }
    ],
    "as": "books"
  }}
])

The other addition here is of course the ability to interpolate the variable through $expr using $match to select the matching items in the "join", but the general premise is a "pipeline within a pipeline" where the inner content can be filtered by matches from the parent. Since they are both "pipelines" themselves we can $limit each result separately.

This would be the next best option to running parallel queries, and actually would be better if the $match were allowed and able to use an index in the "sub-pipeline" processing. So which is does not use the "limit to $push" as the referenced issue asks, it actually delivers something that should work better.

Original Content

You seem have stumbled upon the top "N" problem. In a way your problem is fairly easy to solve though not with the exact limiting that you ask for:

db.books.aggregate([
    { "$group": {
        "_id": {
            "addr": "$addr",
            "book": "$book"
        },
        "bookCount": { "$sum": 1 }
    }},
    { "$group": {
        "_id": "$_id.addr",
        "books": { 
            "$push": { 
                "book": "$_id.book",
                "count": "$bookCount"
            },
        },
        "count": { "$sum": "$bookCount" }
    }},
    { "$sort": { "count": -1 } },
    { "$limit": 2 }
])

Now that will give you a result like this:

{
    "result" : [
            {
                    "_id" : "address1",
                    "books" : [
                            {
                                    "book" : "book4",
                                    "count" : 1
                            },
                            {
                                    "book" : "book5",
                                    "count" : 1
                            },
                            {
                                    "book" : "book1",
                                    "count" : 3
                            }
                    ],
                    "count" : 5
            },
            {
                    "_id" : "address2",
                    "books" : [
                            {
                                    "book" : "book5",
                                    "count" : 1
                            },
                            {
                                    "book" : "book1",
                                    "count" : 2
                            }
                    ],
                    "count" : 3
            }
    ],
    "ok" : 1
}

So this differs from what you are asking in that, while we do get the top results for the address values the underlying "books" selection is not limited to only a required amount of results.

This turns out to be very difficult to do, but it can be done though the complexity just increases with the number of items you need to match. To keep it simple we can keep this at 2 matches at most:

db.books.aggregate([
    { "$group": {
        "_id": {
            "addr": "$addr",
            "book": "$book"
        },
        "bookCount": { "$sum": 1 }
    }},
    { "$group": {
        "_id": "$_id.addr",
        "books": { 
            "$push": { 
                "book": "$_id.book",
                "count": "$bookCount"
            },
        },
        "count": { "$sum": "$bookCount" }
    }},
    { "$sort": { "count": -1 } },

        "books": { "$push": "$books" }
    }},
    { "$sort": { "count": -1 } }
])

So that will actually give you the top 2 "books" from the top two "address" entries.

But for my money, stay with the first form and then simply "slice" the elements of the array that are returned to take the first "N" elements.

Demonstration Code

The demonstration code is appropriate for usage with current LTS versions of NodeJS from v8.x and v10.x releases. That's mostly for the async/await syntax, but there is nothing really within the general flow that has any such restriction, and adapts with little alteration to plain promises or even back to plain callback implementation.

index.js

const { MongoClient } = require('mongodb');
const fs = require('mz/fs');

const uri = 'mongodb://localhost:27017';

const log = data => console.log(JSON.stringify(data, undefined, 2));

  try {
    const client = await MongoClient.connect(uri);

You have to override your ; delimiter with something like $$ to avoid this kind of error.

After your function definition, you can set the delimiter back to ;.

This should work:

DELIMITER $$
CREATE FUNCTION F_Dist3D (x1 decimal, y1 decimal) 
RETURNS decimal
DETERMINISTIC
BEGIN 
  DECLARE dist decimal;
  SET dist = SQRT(x1 - y1);
  RETURN dist;
END$$
DELIMITER ;

There are two ways to do the same instruction, that is, an empty string. The first way is to allocate an empty string on static memory:

char* my_variable = "";

or, if you want to be explicit:

char my_variable = '\0';

The way posted above is only for a character. And, the second way:

#include <string.h>
char* my_variable = strdup("");

Don't forget to use free() with this one because strdup() use malloc inside.

You could possibly use this and use jQuery to update the css height of the elements to make sure it stays in place.

MySQL 5.x specification for decimal datatype is: DECIMAL[(M[,D])] [UNSIGNED] [ZEROFILL]. The answer above is wrong (now corrected) in saying that unsigned decimals are not possible.

To define a field allowing only unsigned decimals, with a total length of 6 digits, 4 of which are decimals, you would use: DECIMAL (6,4) UNSIGNED.

You can likewise create unsigned (ie. not negative) FLOAT and DOUBLE datatypes.

Update on MySQL 8.0.17+, as in MySQL 8 Manual: 11.1.1 Numeric Data Type Syntax:

"Numeric data types that permit the UNSIGNED attribute also permit SIGNED. However, these data types are signed by default, so the SIGNED attribute has no effect.*

As of MySQL 8.0.17, the UNSIGNED attribute is deprecated for columns of type FLOAT, DOUBLE, and DECIMAL (and any synonyms); you should expect support for it to be removed in a future version of MySQL. Consider using a simple CHECK constraint instead for such columns.

if you just want to display a window when you click on a button and undisp this window when you click outside.( or on the button again ) this bellow work good

document.body.onclick = function() { undisp_menu(); };
var menu_on = 0;

function menu_trigger(event){

    if (menu_on == 0)
    {
        // otherwise u will call the undisp on body when 
        // click on the button
        event.stopPropagation(); 

        disp_menu();
    }

    else{
        undisp_menu();
    }

}


function disp_menu(){

    menu_on = 1;
    var e = document.getElementsByClassName("menu")[0];
    e.className = "menu on";

}

function undisp_menu(){

    menu_on = 0;
    var e = document.getElementsByClassName("menu")[0];
    e.className = "menu";

}

don't forget this for the button

<div class="button" onclick="menu_trigger(event)">

<div class="menu">

and the css:

.menu{
    display: none;
}

.on {
    display: inline-block;
}

MessageBox.Show(title, text, messageboxbuttons.yes/no)

This returns a DialogResult which you can check.

For example,

if(MessageBox.Show("","",MessageBoxButtons.YesNo) == DialogResult.Yes)
{
   //do something
}

One way to do this would be to pass the instance of ParentClass to the ChildClass on construction

public ChildClass
{
    private ParentClass parent;

    public ChildClass(ParentClass parent)
    {
        this.parent = parent;
    }

    public void LoadData(DateTable dt)
    {
       // do something
       parent.CurrentRow++; // or whatever.
       parent.UpdateProgressBar(); // Call the method
    }
}

Make sure to pass the reference to this when constructing ChildClass inside parent:

if(loadData){

     ChildClass childClass = new ChildClass(this); // here

     childClass.LoadData(this.Datatable);

}

Caveat: This is probably not the best way to organise your classes, but it directly answers your question.

EDIT: In the comments you mention that more than 1 parent class wants to use ChildClass. This is possible with the introduction of an interface, eg:

public interface IParentClass
{
    void UpdateProgressBar();
    int CurrentRow{get; set;}
}

Now, make sure to implement that interface on both (all?) Parent Classes and change child class to this:

public ChildClass
{
    private IParentClass parent;

    public ChildClass(IParentClass parent)
    {
        this.parent = parent;
    }

    public void LoadData(DateTable dt)
    {
       // do something
       parent.CurrentRow++; // or whatever.
       parent.UpdateProgressBar(); // Call the method
    }
}

Now anything that implements IParentClass can construct an instance of ChildClass and pass this to its constructor.

You can just use an a selector in your stylesheet to define all states of an anchor/hyperlink. For example:

a {
    color: blue;
}

Would override all link styles and make all the states the colour blue.

I somehow absolutely missed the actual command in the accepted answer, so here it is again, bit more visible in its own paragraph, to see how many people are like me

$ docker history --no-trunc <IMAGE_ID>

I had identical problem. To fix it I just changed host from localhost:3306 to just localhost. So error may acour when You sepcify unproper port for connection. It's better to leave it default.

Try this:

System.Configuration.ConfigurationFileMap fileMap = new ConfigurationFileMap(strConfigPath); //Path to your config file
System.Configuration.Configuration configuration = System.Configuration.ConfigurationManager.OpenMappedMachineConfiguration(fileMap);

The original ASCII table is encoded on 7 bits therefore it has 128 characters.

Nowadays most readers/editors use an "extended" ASCII table (from ISO 8859-1), which is encoded on 8 bits and enjoys 256 characters (including Á, Ä, Œ, é, è and other characters useful for european languages as well as mathematical glyphs and other symbols).

While UTF-8 uses the same encoding as the basic ASCII table (meaning 0x41 is A in both codes), it does not share the same encoding for the "Latin Extended-A" block. Which sometimes causes weird characters to appear in words like à la carte or piñata.

Why not to use separate func?

def func(*args, **kwargs):
    return inst.method(args, kwargs)

print pool.map(func, arr)

You're right non-jailbroken phones are limited to Apple's App store and Apple "has the right" to enforce whatever rule, it's totally nonfree territory. However while developing, one won't have to deal with Apple at all. You can use e.g. rsync to upload the code to the device and test it.

From the docs:

from .. import scriptA

You can do this in packages, but not in scripts you run directly. From the link above:

Note that both explicit and implicit relative imports are based on the name of the current module. Since the name of the main module is always "__main__", modules intended for use as the main module of a Python application should always use absolute imports.

If you create a script that imports A.B.B, you won't receive the ValueError.

Yes, something like:

Class<?> clazz = Class.forName(className);
Constructor<?> ctor = clazz.getConstructor(String.class);
Object object = ctor.newInstance(new Object[] { ctorArgument });

That will only work for a single string parameter of course, but you can modify it pretty easily.

Note that the class name has to be a fully-qualified one, i.e. including the namespace. For nested classes, you need to use a dollar (as that's what the compiler uses). For example:

package foo;

public class Outer
{
    public static class Nested {}
}

To obtain the Class object for that, you'd need Class.forName("foo.Outer$Nested").

I am starting out with python and I use id when I use the interactive shell to see whether my variables are assigned to the same thing or if they just look the same.

Every value is an id, which is a unique number related to where it is stored in the memory of the computer.

Any best practices here?

Use the Maven advanced reactor options, more specifically:

-pl, --projects
        Build specified reactor projects instead of all projects
-am, --also-make
        If project list is specified, also build projects required by the list

So just cd into the parent P directory and run:

mvn install -pl B -am

And this will build B and the modules required by B.

Note that you need to use a colon if you are referencing an artifactId which differs from the directory name:

mvn install -pl :B -am

Relational databases have a mathematical basis (set theory, relational theory), which are distilled into SQL == Structured Query Language.

NoSQL's many forms (e.g. document-based, graph-based, object-based, key-value store, etc.) may or may not be based on a single underpinning mathematical theory. As S. Lott has correctly pointed out, hierarchical data stores do indeed have a mathematical basis. The same might be said for graph databases.

I'm not aware of a universal query language for NoSQL databases.

Try using matplotlib.pyplot.ticklabel_format:

import matplotlib.pyplot as plt
...
plt.ticklabel_format(style='sci', axis='x', scilimits=(0,0))

This applies scientific notation (i.e. a x 10^b) to your x-axis tickmarks

Simply just check with the number of characters in the string

1. Add a delegate to view controller ans asign delegate

    class YorsClassName : UITextFieldDelegate {

    }

2. check the number of chars allowed for textfield

func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {
    if textField.text?.count == 1 {
        return false
    }
    return true
}

Note: Here I checked for only char allowed in textField

Just tested and QDir::currentPath() does return the path from which I called my executable.

And a symlink does not "exist". If you are executing an exe from that path you are effectively executing it from the path the symlink points to.

This will remove the last 12 lines

An alternative in Java 8:

String[] strings = list.stream().toArray(String[]::new);

Java 11+:

String[] strings = list.toArray(String[]::new);

You can also do: mydate.toLocaleDateString();

If only one checkbox should be checked in the same time use RadioButtonFor instead:

      @Html.RadioButtonFor(model => model.Type,1, new { @checked = "checked" }) fultime
      @Html.RadioButtonFor(model => model.Type,2) party
      @Html.RadioButtonFor(model => model.Type,3) next option...

If one more one could be checked in the same time use excellent extension: CheckBoxListFor:

If the machine you are on is part of the AD domain, it should have its name servers set to the AD name servers (or hopefully use a DNS server path that will eventually resolve your AD domains). Using your example of dc=domain,dc=com, if you look up domain.com in the AD name servers it will return a list of the IPs of each AD Controller. Example from my company (w/ the domain name changed, but otherwise it's a real example):

    mokey 0 /home/jj33 > nslookup example.ad
    Server:         172.16.2.10
    Address:        172.16.2.10#53

    Non-authoritative answer:
    Name:   example.ad
    Address: 172.16.6.2
    Name:   example.ad
    Address: 172.16.141.160
    Name:   example.ad
    Address: 172.16.7.9
    Name:   example.ad
    Address: 172.19.1.14
    Name:   example.ad
    Address: 172.19.1.3
    Name:   example.ad
    Address: 172.19.1.11
    Name:   example.ad
    Address: 172.16.3.2

Note I'm actually making the query from a non-AD machine, but our unix name servers know to send queries for our AD domain (example.ad) over to the AD DNS servers.

I'm sure there's a super-slick windowsy way to do this, but I like using the DNS method when I need to find the LDAP servers from a non-windows server.

During an object's de-serialization, the class responsible for de-serializing an object creates an instance of the serialized class and then proceeds to populate the serialized fields and properties only after acquiring an instance to populate.

You can make your constructor private or internal if you want, just so long as it's parameterless.

SELECT id, 
       IF(type = 'P', amount, amount * -1) as amount
FROM report

See http://dev.mysql.com/doc/refman/5.0/en/control-flow-functions.html.

Additionally, you could handle when the condition is null. In the case of a null amount:

SELECT id, 
       IF(type = 'P', IFNULL(amount,0), IFNULL(amount,0) * -1) as amount
FROM report

The part IFNULL(amount,0) means when amount is not null return amount else return 0.

Just use the -H parameter several times:

curl -H "Accept-Charset: utf-8" -H "Content-Type: application/x-www-form-urlencoded" http://www.some-domain.com

Using hamishmcn's answer as a template I was able to search for a line in a file that match my regex and replacing it with empty string.

import re 

fin = open("in.txt", 'r') # in file
fout = open("out.txt", 'w') # out file
for line in fin:
    p = re.compile('[-][0-9]*[.][0-9]*[,]|[-][0-9]*[,]') # pattern
    newline = p.sub('',line) # replace matching strings with empty string
    print newline
    fout.write(newline)
fin.close()
fout.close()

Optimizing Antonio Max answer:

$xmlfile = 'yourfile.xml';
$xmlparser = xml_parser_create();

// open a file and read data
$fp = fopen($xmlfile, 'r');
//9999999 is the length which fread stops to read.
$xmldata = fread($fp, 9999999);

// converting to XML
$xml = simplexml_load_string($xmldata, "SimpleXMLElement", LIBXML_NOCDATA);

// converting to JSON
$json = json_encode($xml);
$array = json_decode($json,TRUE);

Last resort option when nothing else seems to work: close and reopen IntelliJ.

My issue was with reverting a Git commit, which happened to change the Java SDK configured for the Project to a no longer installed version of the JDK. But fixing that back still didn't allow me to run the program. Restarting IntelliJ fixed this

If the file is in your parent folder, eg. follower.txt, you can simply use open('../follower.txt', 'r').read()

for i=1,#target do
    game.Players.target[i].Character:BreakJoints()
end

Is incorrect, if "target" contains "FakeNameHereSoNoStalkers" then the run code would be:

game.Players.target.1.Character:BreakJoints()

Which is completely incorrect.

c = game.Players:GetChildren()

Never use "Players:GetChildren()", it is not guaranteed to return only players.

Instead use:

c = Game.Players:GetPlayers()

if msg:lower()=="me" then
    table.insert(people, source)
    return people

Here you add the player's name in the list "people", where you in the other places adds the player object.

Fixed code:

local Admins = {"FakeNameHereSoNoStalkers"}

function Kill(Players)
    for i,Player in ipairs(Players) do
        if Player.Character then
            Player.Character:BreakJoints()
        end
    end
end

function IsAdmin(Player)
    for i,AdminName in ipairs(Admins) do
        if Player.Name:lower() == AdminName:lower() then return true end
    end
    return false
end

function GetPlayers(Player,Msg)
    local Targets = {}
    local Players = Game.Players:GetPlayers()

    if Msg:lower() == "me" then
        Targets = { Player }
    elseif Msg:lower() == "all" then
        Targets = Players
    elseif Msg:lower() == "others" then
        for i,Plr in ipairs(Players) do
            if Plr ~= Player then
                table.insert(Targets,Plr)
            end
        end
    else
        for i,Plr in ipairs(Players) do
            if Plr.Name:lower():sub(1,Msg:len()) == Msg then
                table.insert(Targets,Plr)
            end
        end
    end
    return Targets
end

Game.Players.PlayerAdded:connect(function(Player)
    if IsAdmin(Player) then
        Player.Chatted:connect(function(Msg)
            if Msg:lower():sub(1,6) == ":kill " then
                Kill(GetPlayers(Player,Msg:sub(7)))
            end
        end)
    end
end)

This might not be a popular option, but sometimes the scripts end up being distributed in various chunks, in that case I've found this to be a quick fix

if(window.onload != null){var f1 = window.onload;}
window.onload=function(){
    //do something

    if(f1!=null){f1();}
}

then somewhere else...

if(window.onload != null){var f2 = window.onload;}
window.onload=function(){
    //do something else

    if(f2!=null){f2();}
}

this will update the onload function and chain as needed

As an addendum to @xmechanix's answer, I noticed through writing the contents to a file:

echo | set /p dummyName=Hello World > somefile.txt

That this will add an extra space at the end of the printed string, which can be inconvenient, specially since we're trying to avoid adding a new line (another whitespace character) to the end of the string.

Fortunately, quoting the string to be printed, i.e. using:

echo | set /p dummyName="Hello World" > somefile.txt

Will print the string without any newline or space character at the end.

First, create a directory(folder) in the root of your local repo that will contain the screenshots you want added. Let’s call the name of this directory screenshots. Place the images (JPEG, PNG, GIF,` etc) you want to add into this directory.

Android Studio Workspace Screenshot

Secondly, you need to add a link to each image into your README. So, if I have images named 1_ArtistsActivity.png and 2_AlbumsActivity.png in my screenshots directory, I will add their links like so:

 <img src="screenshots/1_ArtistsActivity.png" height="400" alt="Screenshot"/> <img src=“screenshots/2_AlbumsActivity.png" height="400" alt="Screenshot"/>

If you want each screenshot on a separate line, write their links on separate lines. However, it’s better if you write all the links in one line, separated by space only. It might actually not look too good but by doing so GitHub automatically arranges them for you.

Finally, commit your changes and push it!

Change

dateFormat: 'dd/mm/yyyy'

to

format: 'dd/mm/yyyy'

Looks like you just misread some documentation!

DECLARE @source varbinary(max),  
@encoded_base64 varchar(max),  
@decoded varbinary(max) 
SET @source = CONVERT(varbinary(max), 'welcome') 
-- Convert from varbinary to base64 string 
SET @encoded_base64 = CAST(N'' AS xml).value('xs:base64Binary(sql:variable       
("@source"))', 'varchar(max)') 
  -- Convert back from base64 to varbinary 
   SET @decoded = CAST(N'' AS xml).value('xs:base64Binary(sql:variable             
  ("@encoded_base64"))', 'varbinary(max)') 

 SELECT
  CONVERT(varchar(max), @source) AS [Source varchar], 
   @source AS [Source varbinary], 
     @encoded_base64 AS [Encoded base64], 
     @decoded AS [Decoded varbinary], 
     CONVERT(varchar(max), @decoded) AS [Decoded varchar]

This is usefull for encode and decode.

If it's really required to access SessionFactory through @Autowire, I'd rather configure another EntityManagerFactory and then use it to configure the SessionFactory bean, like following:

@Configuration
public class SessionFactoryConfig {

@Autowired 
DataSource dataSource;

@Autowired
JpaVendorAdapter jpaVendorAdapter;

@Bean
@Primary
public EntityManagerFactory entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
    emf.setDataSource(dataSource);
    emf.setJpaVendorAdapter(jpaVendorAdapter);
    emf.setPackagesToScan("com.hibernateLearning");
    emf.setPersistenceUnitName("default");
    emf.afterPropertiesSet();
    return emf.getObject();
}

@Bean
public SessionFactory setSessionFactory(EntityManagerFactory entityManagerFactory) {
    return entityManagerFactory.unwrap(SessionFactory.class);
} }

No need to get too complicated. If all you need is ² then use the unicode representation.

http://en.wikipedia.org/wiki/Unicode_subscripts_and_superscripts

(which is how I assume you got the ² to appear in your question. )

try this method given below, modify to suit your need.

SELECT
  employment_status.staff_type,
  COUNT(monthly_pay_register.age),
  monthly_pay_register.BASIC_SALARY,
  monthly_pay_register.TOTAL_MONTHLY_ALLOWANCES,
  monthly_pay_register.MONTHLY_GROSS,
  monthly_pay_register.TOTAL_MONTHLY_DEDUCTIONS,
  monthly_pay_register.MONTHLY_PAY
FROM 
  (monthly_pay_register INNER JOIN deduction_logs 
ON
  monthly_pay_register.employee_info_employee_no = deduction_logs.employee_no)
INNER JOIN
  employment_status ON deduction_logs.employee_no = employment_status.employee_no
WHERE
  monthly_pay_register.`YEAR`=2017
and 
  monthly_pay_register.`MONTH`='may'

Using solve with a single parameter is a request to invert a matrix. The error message is telling you that your matrix is singular and cannot be inverted.

I had the same problem when I transferred the ownership of my repository to another user, at first I tried to use git branch --set-upstream-to origin/master master but the terminal complained so after a little bit of looking around I used the following commands
git fetch
git branch --set-upstream-to origin/master master
git pull
and everything worked again

try this:

"String goes here".PadLeft(20,' ');
"String goes here".PadRight(20,' ');

for the center get the length of the string and do padleft and padright with the necessary characters

int len = "String goes here".Length;
int whites = len /2;
"String goes here".PadRight(len + whites,' ').PadLeft(len + whites,' ');

Change your code to.

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

There was syntax error in your query.

This'll work:

<!DOCTYPE HTML>
<html>
    <head>
        <script type="text/javascript">
            function myFunc(id)
            {
                alert(id);
            }
        </script>
    </head>

    <body>
        <button id="button1" class="MetroBtn" onClick="myFunc(this.id);">Btn1</button>
        <button id="button2" class="MetroBtn" onClick="myFunc(this.id);">Btn2</button>
        <button id="button3" class="MetroBtn" onClick="myFunc(this.id);">Btn3</button>
        <button id="button4" class="MetroBtn" onClick="myFunc(this.id);">Btn4</button>
    </body>
</html>

In System.Diagnostics,

Debug.Write()
Debug.WriteLine()

etc. will print to the Output window in VS.

in keyword allows you to loop over a collection and check if there is a member in the collection that is equal to the element.

In this case string is nothing but a list of characters:

dog = "xdasds"
if "x" in dog:
     print "Yes!"

You can check a substring too:

>>> 'x' in "xdasds"
True
>>> 'xd' in "xdasds"
True
>>> 
>>> 
>>> 'xa' in "xdasds"
False

Think collection:

>>> 'x' in ['x', 'd', 'a', 's', 'd', 's']
True
>>> 

You can also test the set membership over user defined classes.

For user-defined classes which define the __contains__ method, x in y is true if and only if y.__contains__(x) is true.

This works like a charm ;)

<ul class="nav nav-pills" ng-init="selectedType = 'return'">
    <li role="presentation" ng-class="{'active':selectedType === 'return'}"
        ng-click="selectedType = 'return'"><a href="#return">return

    </a></li>
    <li role="presentation" ng-class="{'active':selectedType === 'oneway'}"
        ng-click="selectedType = 'oneway'"><a href="#oneway">oneway
    </a></li>
</ul>

There are really nice answers for this particular question, so there is no point to write my own explanation. So I will try to contribute with an excellent resource about different classes of computational complexity.

For someone who thinks that computational complexity is only about P and NP, here is the most exhaustive resource about different computational complexity problems. Apart from problems asked by OP, it listed approximately 500 different classes of computational problems with nice descriptions and also the list of fundamental research papers which describe the class.

Where the range is multiple cells:

Excel.Worksheet sheet = workbook.ActiveSheet;
Excel.Range rng = (Excel.Range) sheet.get_Range(sheet.Cells[1, 1], sheet.Cells[3,3]);

Where range is one cell:

Excel.Worksheet sheet = workbook.ActiveSheet;
Excel.Range rng = (Excel.Range) sheet.Cells[1, 1];

If your XSLT processor supports EXSLT, you can use str:tokenize, otherwise, the link contains an implementation using functions like substring-before.

Try this:

function createcodes() {

    $('.authors-list tr').each(function () {
        //processing this row
        //how to process each cell(table td) where there is checkbox
        $(this).find('td input:checked').each(function () {

             // it is checked, your code here...
        });
    });
}

The easiest way would be to specify

SELECT productid FROM product where purchase_date > sysdate-30;

Remember this sysdate above has the time component, so it will be purchase orders newer than 03-06-2011 8:54 AM based on the time now.

If you want to remove the time conponent when comparing..

SELECT productid FROM product where purchase_date > trunc(sysdate-30);

And (based on your comments), if you want to specify a particular date, make sure you use to_date and not rely on the default session parameters.

SELECT productid FROM product where purchase_date > to_date('03/06/2011','mm/dd/yyyy')

And regardng the between (sysdate-30) - (sysdate) comment, for orders you should be ok with usin just the sysdate condition unless you can have orders with order_dates in the future.

I use a generic query I call "dump" (why? I don't know) that looks like this:

SET NEWPAGE NONE
SET PAGESIZE 0
SET SPACE 0
SET LINESIZE 16000
SET ECHO OFF
SET FEEDBACK OFF
SET VERIFY OFF
SET HEADING OFF
SET TERMOUT OFF
SET TRIMOUT ON
SET TRIMSPOOL ON
SET COLSEP |

spool &1..txt

@@&1

spool off
exit

I then call SQL*Plus passing the actual SQL script I want to run as an argument:

sqlplus -S user/password@database @dump.sql my_real_query.sql

The result is written to a file

my_real_query.sql.txt

.

You could use the daff package (which wraps the daff.js library using the V8 package):

library(daff)

diff_data(data_ref = a2,
          data = a1)

produces the following difference object:

Daff Comparison: ‘a2’ vs. ‘a1’ 
  First 6 and last 6 patch lines:
   @@   a   b
1 ... ... ...
2       3   c
3 +++   4   d
4 +++   5   e
5 ... ... ...
6 ... ... ...
7       3   c
8 +++   4   d
9 +++   5   e

The tabular diff format is described here and should be pretty self-explanatory. The lines with +++ in the first column @@ are the ones which are new in a1 and not present in a2.

The difference object can be used to patch_data(), to store the difference for documentation purposes using write_diff() or to visualize the difference using render_diff():

render_diff(
    diff_data(data_ref = a2,
              data = a1)
)

generates a neat HTML output:

In the following example, eye is changed by PersonB, while leg stays the same. This is because a private variable makes a copy of itself to the method, so that its original value stays the same; while a private static value only has one copy for all the methods to share, so editing its value will change its original value.

public class test {
private static int eye=2;
private int leg=3;

public test (int eyes, int legs){
    eye = eyes;
    leg=leg;
}

public test (){
}

public void print(){
    System.out.println(eye);
    System.out.println(leg);
}

public static void main(String[] args){
    test PersonA = new test();      
    test PersonB = new test(14,8);
    PersonA.print();    
}

}

There is no way you can delete a pull request yourself -- you and the repo owner (and all users with push access to it) can close it, but it will remain in the log. This is part of the philosophy of not denying/hiding what happened during development.

However, if there are critical reasons for deleting it (this is mainly violation of Github Terms of Service), Github support staff will delete it for you.

Whether or not they are willing to delete your PR for you is something you can easily ask them, just drop them an email at [email protected]

UPDATE: Currently Github requires support requests to be created here: https://support.github.com/contact

Use SimpleNamespace:

>>> from types import SimpleNamespace   
>>> d = dict(x=[1, 2], y=['a', 'b'])
>>> ns = SimpleNamespace(**d)
>>> ns.x
[1, 2]
>>> ns
namespace(x=[1, 2], y=['a', 'b'])

Another way

_details.Sort((s1, s2) => s1.CompareTo(s2)); 

The T doesn't really stand for anything. It is just the separator that the ISO 8601 combined date-time format requires. You can read it as an abbreviation for Time.

The Z stands for the Zero timezone, as it is offset by 0 from the Coordinated Universal Time (UTC).

Both characters are just static letters in the format, which is why they are not documented by the datetime.strftime() method. You could have used Q or M or Monty Python and the method would have returned them unchanged as well; the method only looks for patterns starting with % to replace those with information from the datetime object.

Here is a block to print out unicode chars between \u00c0 to \u00ff:

char[] ca = {'\u00c0'};
for (int i = 0; i < 4; i++) {
    for (int j = 0; j < 16; j++) {
        String sc = new String(ca);
        System.out.print(sc + " ");
        ca[0]++;
    }
    System.out.println();
}

Also you may need:

• SystemParameters.VirtualScreenWidth
• SystemParameters.VirtualScreenHeight

to get the combined size of all monitors and not one in particular.

well, you could create the is_number function to call so your code works.

create or replace function is_number(param varchar2) return boolean
 as
   ret number;
 begin
    ret := to_number(param);
    return true;
 exception
    when others then return false;
 end;

EDIT: Please defer to Justin's answer. Forgot that little detail for a pure SQL call....

I thought I'd share the function I put together. Hopefully it can save you time.

It was originally used to track timing of a text-based script, so the output is in text form. But you can easily modify it to HTML if you prefer.

It will do all the calculations for you for how much time has been spent since the start of the script and in each step. It formats all the output with 3 decimals of precision. (Down to milliseconds.)

Once you copy it to the top of your script, all you do is put the recordTime function calls after each piece you want to time.

Copy this to the top of your script file:

$tRecordStart = microtime(true);
header("Content-Type: text/plain");
recordTime("Start");

function recordTime ($sName) {
  global $tRecordStart;
  static $tStartQ;
  $tS = microtime(true);
  $tElapsedSecs = $tS - $tRecordStart;
  $tElapsedSecsQ = $tS - $tStartQ;
  $sElapsedSecs = str_pad(number_format($tElapsedSecs, 3), 10, " ", STR_PAD_LEFT);
  $sElapsedSecsQ = number_format($tElapsedSecsQ, 3);
  echo "//".$sElapsedSecs." - ".$sName;
  if (!empty($tStartQ)) echo " In ".$sElapsedSecsQ."s";
  echo "\n";
  $tStartQ = $tS;
}

To track the time that passes, just do:

recordTime("What We Just Did")

For example:

recordTime("Something Else")
//Do really long operation.
recordTime("Really Long Operation")
//Do a short operation.
recordTime("A Short Operation")
//In a while loop.
for ($i = 0; $i < 300; $i ++) {
  recordTime("Loop Cycle ".$i)
}

Gives output like this:

//     0.000 - Start
//     0.001 - Something Else In 0.001s
//    10.779 - Really Long Operation In 10.778s
//    11.986 - A Short Operation In 1.207s
//    11.987 - Loop Cycle 0 In 0.001s
//    11.987 - Loop Cycle 1 In 0.000s
...
//    12.007 - Loop Cycle 299 In 0.000s

Hope this helps someone!

I had this problem not because I'm storing in different collations, but because my column type is JSON, which is binary.

Fixed it like this:

select table.field COLLATE utf8mb4_0900_ai_ci AS fieldName

As of Python 3.6 (2016) you can use f-strings to substitute variables:

>>> origin = "London"
>>> destination = "Paris"
>>> f"from {origin} to {destination}"
'from London to Paris'

Note the f" prefix. If you try this in Python 3.5 or earlier, you'll get a SyntaxError.

See https://docs.python.org/3.6/reference/lexical_analysis.html#f-strings

If you want to insert this formula =SUMIFS(B2:B10,A2:A10,F2) into cell G2, here is how I did it.

Range("G2")="=sumifs(B2:B10,A2:A10," & _

To split a line of code, add an ampersand, space and underscore.

If you are fine with non-printable symbols in your json, then add ensure_ascii=False to dumps call.

>>> json.dumps(your_data, ensure_ascii=False)

If ensure_ascii is false, then the return value will be a unicode instance subject to normal Python str to unicode coercion rules instead of being escaped to an ASCII str.

Knowing the scope of each can make things easier to remember.

process is node's global object, and .cwd() returns where node is running.

__dirname is module's property, and represents the file path of the module. In node, one module resides in one file.

Similarly, __filename is another module's property, which holds the file name of the module.

In Python 3.x, you need to import urllib.parse.quote:

>>> import urllib.parse
>>> urllib.parse.quote("châteu", safe='')
'ch%C3%A2teu'

According to Python 2.x urllib module documentation:

NOTE

The urllib module has been split into parts and renamed in Python 3 to urllib.request, urllib.parse, and urllib.error.

ValueError: Original message. My custom error message.

In Java 8, if you want to have a list of non-repeating N random integers in range (a, b), where b is exclusive, you can use something like this:

Random random = new Random();
List<Integer> randomNumbers = random.ints(a, b).distinct().limit(N).boxed().collect(Collectors.toList());

You can see all the privileges for all directories wit the following

SELECT *
from all_tab_privs
where table_name in
  (select directory_name 
   from dba_directories);

The following gives you the sql statements to grant the privileges should you need to backup what you've done or something

select 'Grant '||privilege||' on directory '||table_schema||'.'||table_name||' to '||grantee 
from all_tab_privs 
where table_name in (select directory_name from dba_directories);

Thank You! Please mark my answer if it helps you!

My preferred is:

Commenting in a Bash script

This will have some overhead, but technically it does answer your question

echo abc `#put your comment here` \
     def `#another chance for a comment` \
     xyz etc

And for pipelines specifically, there is a cleaner solution with no overhead

echo abc |        # normal comment OK here
     tr a-z A-Z | # another normal comment OK here
     sort |       # the pipelines are automatically continued
     uniq         # final comment

How to put a line comment for a multi-line command

Similar to @joe_deniable 's answer the thing I found with my own projects was that gradle would output that kind of error when there was a misconfiguration of my system.

I discovered that by running gradlew installDebug or similar command from the terminal I got better output as to what the real problem was.

e.g. initially it turns out my JAVA_HOME was not setup correctly. Then I discovered it encountered errors because I didn't have a package space setup correctly. Etc.

I have a site where a logging-script writes a new line of text to a textfile after an action from the user, who can be using any OS.

Using PHP_EOL don't seem to be optimal in this case. If the user is on Mac OS and writes to the textfile it will put \n. When opening the textfile on a windows computer it doesn't show a line break. For this reason i use "\r\n" instead which works when opening the file on any OS.

just for the record you can always compare using JSON.stringify

const arr = [1,2,3]; expect(JSON.stringify(arr)).toBe(JSON.stringify([1,2,3])); expect(JSON.stringify(arr)).toEqual(JSON.stringify([1,2,3]));

It's all meter of taste, this will also work for complex literal objects

Go to your respective git repo, then run the below command:

git diff filename

It will open the file with the changes marked, press return/enter key to scroll down the file.

P.S. filename should include the full path of the file or else you can run without the full file path by going in the respective directory/folder of the file

This is how i registered my domain:

sudo letsencrypt --apache -d mydomain.com

Then it was possible to use the same command with additional domains and follow the instructions:

sudo letsencrypt --apache -d mydomain.com,x.mydomain.com,y.mydomain.com

Instead of creating selector, Best way to create a style.

<style name="AppTheme.BottomBar">
    <item name="colorPrimary">@color/colorAccent</item> 
</style>

and to change the text size, selected or non selected.

<dimen name="design_bottom_navigation_text_size" tools:override="true">11sp</dimen>
<dimen name="design_bottom_navigation_active_text_size" tools:override="true">12sp</dimen>

Enjoy Android!
